[Technical area]

The present invention relates to a cartridge, a combination of a cartridge and a printing device (or a portion thereof), and / or a printing material supply system including the cartridge and a printing device.

[State of the art]

Various mechanisms have been proposed for attaching a cartridge to a printing device and removing a cartridge from a printing device. Examples of such mechanisms are in the US Publication No. 2005/0151811 (the the JP-A-2007-230249 corresponds), the U.S. Patent No. 7,008,053 (that the JP-A-2005-022345 corresponds), the U.S. Patent No. 6,276,780 (that the JP-A-2002-019142 corresponds), the U.S. Patent 6,955,422 , the U.S. Patent 6,074,042 and the U.S. Patent No. 7,018,030 disclosed.

[Summary]

[Technical task]

The US Publication No. 2005/0151811 discloses a cartridge with a latch 3 and electrical contact pads 102 , The lever 3 includes an anchoring section 6 for engagement with the printer. The anchoring section 6 is far away from the contact pads 102 arranged. Since the anchoring section 6 far from the cartridge ports, engagement with the printer can only provide a limited contribution to the accuracy and stability of the location of the cartridge ports with respect to the respective printer ports.

In addition, the lever needs 3 in the US Publication No. 2005/0151811 be long enough to reach a user-accessible location so that the user can operate it. It also protrudes far from the side wall of the cartridge. Such a large lever results in a larger cartridge, which also results in a larger printer to which the cartridge is attached and removed, as well as a bulky package for the transport and distribution of the cartridges, which in turn reduces costs be increased for transport and parts.

In addition, the cartridge structure includes the anchoring portion 6 connects to the cartridge-side ports, a flexible portion of the lever 3 , Even if the anchoring section 6 can firmly engage with the printer, a vibration generated during printing operations by the flexible portion of the lever 3 be transferred to the cartridge ports and so affect the arrangement of the cartridge ports with respect to the printer ports. This is particularly a problem with on-carriage ink cartridges, such as those in the US Publication No. 2005/0151811 as they are attached to a carriage of a printer to which the print head is attached. For on-carriage printers, the carriage is scanned forward and backward across the print media during printing operations. The ink cartridges in the carriage are exposed to a large accelerating force each time the scanning direction is changed, in addition to other vibrations generated during printing operations.

The lever in the US Publication No. 2005/0151811 is integrally formed with the cartridge and elastically deformable. In this construction, the material used to make the cartridge is a material having sufficient moldability to form this structure and also having sufficient flexibility and durability required for the lever to engage during engagement with the printer and release to elastically deform the printer.

The lever may deform plastically under user manipulations. Such plastic deformation of the lever can cause misalignment of position between cartridge-side ports and printer ports, which can result in poor electrical connection.

Plastic deformation also reduces the durability of the lever. In addition, must during the packaging of the cartridge special measures, such as those in the U.S. Patent No. 7,018,030 be taken to prevent creep of the lever while the cartridge is packed, especially when the cartridge is packaged in a vacuum package.

The U.S. Patent No. 6,276,780 discloses a cartridge without memory or electrical connections. Since this type of cartridge does not require electrical connection to the printer, there is no need to include a structure or structure for maintaining a stable location and orientation of cartridge ports to printer ports.

In addition, the cartridge is by a latching mechanism 132 (in 9 - 16 of U.S. Patent No. 6,276,780 ) is attached to the printer, which is arranged on the printer. Cartridge side latching ramps 220 that with the latch mechanism 132 engage, are far away from the axis of rotation of the latching mechanism 132 in the direction in which the cartridge is removed from the printer. As a result, if a resilient element 156 or a compression force seal 152 a force (indicated by the arrow X in 12 of US Pat. No. 6,276,780) in the direction toward the cartridge in which the cartridge is removed from the printer, this force is easily converted into a force which interferes with the engagement of the support portion 134 from the cartridge loading ramps 220 so that the cartridge can be disconnected from the printer while the printer is being used. Since the engagement structure disclosed in US Pat. No. 6,276,780 involves this inherent risk of the cartridge being separated from the printer, it is not intended for use with those disclosed in U.S. Pat US Publication No. 2005/0151811 disclosed constructions which require proper contact between the cartridge ports and printer ports. In addition, the contact between the cartridge and printer ports in the structures of US Publication No. 2005/0151811 exerts a force from the terminals of the printer in the lateral direction on the cartridge, so that the cartridge can move in the lateral direction. The latch mechanism 132 U.S. Patent No. 6,276,780 is not suitable for the cartridge of US Publication No. 2005/0151811, at least for the reason that it may not be adapted to accommodate the movement of the cartridge in the lateral direction, such that the latch mechanism 132 is released from the cartridge.

The U.S. Patent 6,074,042 discloses an ink cartridge with electrical contacts 54 , As in the 12A to 13B the same is shown are the electrical contacts 54 at the leading edge of the direction in which the cartridge is attached to the printer. In this construction, the electrical contacts press 54 the cartridge just against electrical contacts 104 the spring-loaded printer when the cartridge is attached to the printer. Metal oxidation, oil or other non-conductive material on the outer surface of the electrical metal contacts 54 may be introduced between the conductive metal of the cartridge and printer electrical contacts, possibly hindering the electrical connection between the cartridge and the printer.

The U.S. Patent 6,955,422 disclosed for example in the 2a to 2d a cartridge 1 containing a storage device 7 with electrodes 7a having. The electrodes 7a are aligned substantially parallel to the direction of cartridge insertion into the printer. In this construction, the printer electrodes slide 106 over a long distance over the surface of the board (at which the electrodes 7a are formed). The surface of the board is usually covered with an electrically insulating resin material. When the printer electrodes 106 scratching the board, they can damage this insulation, causing fragments of the insulation to chip off the board. The insulation fragments may be between the printer electrodes 106 and the cartridge electrodes 7a hang and cause a poor or otherwise unreliable electrical connection between the printer and the cartridge.

As in the 5 to 6B of U.S. Patent 6,955,422 is shown is the printer with a leaf spring 103 which exerts an urging force which is the surface of the storage device 7 against the printer electrodes 106 pushes when the cartridge is attached to the printer and the cartridge 1 moves upwards when the cartridge is pulled out of the printer.

The U.S. Patent No. 7,008,053 revealed in 5 an elastic piece 40 provided on the printer. When the cartridge is fully attached to the printer, the lower end is located 40a the elastic piece 40 on a flat surface 12a at the upper portion of the protrusion portion 12 at which the electrodes 14 are arranged. The concern between the lower end 40b and the flat surface 12a limits movement of the protrusion portion 12 up. However, the structure of U.S. Patent No. 7,008,053 does not include any close to the projecting portion 12 arranged means for limiting a movement of the projecting portion 12 downward. As a result, the projecting portion 12 can vibrate quite freely vertically during operation of the printer and therefore can cause the electrodes misaligned or disconnected from the printer ports.

In the presence of various attachment and detachment mechanisms, there is a need to reduce the overall size of a printer for ease of use and ease of installation. To reduce the size of the printer, it is usually necessary to reduce the sizes of a large number of components that make up the printer and relevant elements. These components and relevant elements include a cartridge mounted on the printer and a cartridge attachment structure for mounting the cartridge.

For improved use of the printer, information regarding the print material contained in the cartridge (for example, information regarding the remaining amount of print material) is often displayed on the monitor of the printer. The cartridge attached to this printer would have a board with a memory for storing the information regarding the printing material. The board has ports (cartridge-side ports) used to send information to the printer and receive information from the printer. The information regarding the printing material is transferred between the memory and a controller of the printer through the contact of these cartridge side terminals and terminals on the printer (device side terminals). Accordingly, it is necessary to maintain a stable electrical connection between the cartridge-side terminals and the device-side terminals.

As will be described below, there is no known mechanism to meet these requirements in a fully acceptable manner.

This problem is not limited to a cartridge containing ink for printing, but generally also occurs in printing apparatuses and / or cartridges adapted to supply or eject various other printing materials (for example, toner) as well as ink.

Consequently, there is a need to ensure a stable electrical connection between cartridge-side ports and device-side ports. In addition, there is a need to achieve size reduction of a cartridge, a printer and a printing material supply system including the cartridge attached to the printer.

[Solution of the task]

In order to more appropriately achieve at least part of the foregoing, the present invention provides various aspects and embodiments, which are described below.

First aspect:

A cartridge removably attached to a printing apparatus, the printing apparatus comprising a cartridge mounting structure constructed to include: (i) a device-side lower wall member; (ii) a first apparatus-side sidewall member which may be located at a front side thereof and provided so as to intersect the apparatus-side lower wall member; and (iii) a second apparatus-side sidewall member that may be located at a rear side thereof and is provided so as to intersect the apparatus-side lower wall member and confront the first apparatus-side sidewall member. The apparatus may include a printing material supply structure which may be in the form of a tube configured to have a base end provided on the apparatus side lower wall member and a peripheral end to be connected to the cartridge, and configured to receive a printing material contained in the cartridge to feed a head. The apparatus preferably includes a plurality of device-side electrical contact terminals that may be provided in a device-side corner portion where the device-side bottom wall member intersects the first (front) device side sidewall member. The apparatus may further include a lever provided on the first (front) device side sidewall member in a rotatable manner to be used for attaching the cartridge to the printing device and removing the cartridge therefrom. Here, a Z-axis represents an axis that is parallel to a center axis C of the printing material supply tube, an X-axis represents an axis along which the printing material supply tube and the device-side terminals are disposed and perpendicular to the Z-axis, and For example, a Y-axis represents an axis that is perpendicular to both the Z-axis and the X-axis. A + Z-axis direction represents a direction along the Z-axis from the base end to the circumferential end of the printing material supply tube, which may be an upward direction. An -Z axis direction represents a direction opposite to the + Z axis direction. A + X axis direction represents a direction along the X axis from the printing material supply tube to the device side terminals, which may be a forward direction. An -X axis direction represents a direction opposite to the + X axis direction A + Y axis direction represents a direction along the Y axis that is one end and may be a lateral direction, and a -Y axis direction represents a direction along the Y axis, and the other end runs. The apparatus may be constructed such that the device side terminals are in contact with the cartridge to apply a force, which may be a resilient or elastic force, in a certain direction including a + Z axis direction component in a state to the cartridge exercise in which the cartridge is attached to the cartridge attachment structure. The lever may be an actuator at the + Z axis direction end (which may be the upper end) and a first device side restricting member at the -Z axis direction end (which may be the lower end) for locking the cartridge and accordingly restricting the movement of the cartridge have the + Z-axis direction. The lever may be configured to rotate about a predetermined position between the operating member and the first apparatus-side restricting member as an axis of rotation. Herein, the X-axis, the Y-axis and the Z-axis with respect to the cartridge in the mounted state correspond to an X-axis, a Y-axis and a Z-axis of the cartridge, respectively. The cartridge may include: a first surface disposed on the -Z axis direction side and a second surface disposed on the + Z axis direction side as two surfaces opposed to each other in the Z axis direction; a third surface disposed on the + X-axis direction side and a fourth surface disposed on the -X-axis direction side as two surfaces facing each other in the X-axis direction and intersecting the first surface and the second surface; a corner portion arranged to connect the first surface to the third surface; a tapered surface provided so as to form part of the corner portion and inclined in a certain direction including the + X axis direction component and the -Z axis direction component. A printing material supply structure may be provided on the first surface to be connected to the printing material supply pipe. A plurality of cartridge side terminals may be provided corresponding to the respective device side terminals and disposed on the slanted surface to receive a force in a certain direction including the + Z axis direction component from the device side terminals. Because of the inclination at the contact area, the force may also have an -X axis direction component. The cartridge may further include a first cartridge-side restricting portion adapted to be detected by the first apparatus-side restricting member, thereby restricting movement of the cartridge in the + Z-axis direction.

The above structure may be provided with one or both of two features in the following two embodiments. In one embodiment, the additional feature is that the first cartridge-side restricting portion is provided at a predetermined position on the third surface near to a cut portion where the third surface intersects the tapered surface. In another embodiment, the cartridge-side terminals include a first terminal including a first outer part disposed at the outermost end in the + Y-axis direction; and a second terminal including a second outer part disposed at the outermost end in the -Y axis direction, wherein the first cartridge-side restricting portion is not disposed outside but within a range between the first outer part and the second outer part in the Y-axis direction is.

The cartridge according to a first aspect of the invention has the first cartridge-side restricting portion which engages with the lever of the printing device. Since the lever is not integrally formed with the cartridge, the material for making the cartridge may be different from the material used to make the lever. In addition, the material of the cartridge may be selected with less regard to flexibility and durability requirements and greater attention to other properties, such as resistance to ink. Therefore, various plastics, thermoplastics and resins can be used to form the various components.

In addition, since the lever is not disposed on the cartridge, no special care is necessary to prevent creep deformation of the lever when packing the cartridge for transportation and distribution. This simplifies the packaging requirements and improves the user-friendliness.

Since the lever is not an integral part of the cartridge, the cartridge can be made smaller. This also enables a reduction in size of the packaging material, such as a paper or a box used for packaging the cartridge for the transport or distribution of the cartridge, thereby advantageously reducing the transport costs and the part costs.

Since the lever is not integral with the cartridge, the first cartridge-side restricting portion can be small in size and easy Structure and one compared with those in the US Publication No. 2005/0151811 be described structures higher rigidity. As a result, the likelihood of plastic deformation of the first cartridge-side restricting portion is significantly reduced. In the attached condition, the cartridge can be held in the proper position in the cartridge attachment structure, thereby maintaining normal or good contact between the cartridge side ports and the device side ports and reducing the likelihood of poor continuity. In the cartridge of the first aspect, since the first cartridge-side restricting portion may have a small size and simple structure, unlike the cartridges of US Publication No. 2005/0151811, no special care is taken to prevent creeping deformation of the lever in packaging for the cartridge Transport and distribution of the cartridge required. This improves the experience of the user and the ease of use.

In the cartridge according to the first embodiment of the first aspect, the first cartridge side restricting portion may be provided on the -Z axis direction side of the rotational axis of the lever. Even if the force in the direction including the + Z-axis direction component is exerted by the jig-side terminals to move the cartridge in the + Z-axis direction, the lever serves to move the cartridge in the + Z-axis direction to restrict. This reduces the likelihood that the first cartridge side restricting portion will be released or released from the first apparatus side restricting member, thereby ensuring a stable electrical connection between the cartridge side terminals and the apparatus side terminals and reducing the likelihood of poor continuity. The first jig-side restricting member may move with the movement of the cartridge in the -X-axis direction about the rotation axis of the lever when a force in the -X-axis direction is exerted on the attached cartridge from the jig-side terminals. This reduces the likelihood that the first cartridge side restricting portion is decoupled from the first apparatus side restricting member.

In the cartridge according to the first aspect, the first cartridge-side restricting portion is provided at the predetermined position on the third surface near to the cut part. The cartridge can therefore be attached to the cartridge attachment structure at a position close to the contact between the cartridge side ports and the device side ports. This reduces the likelihood of misalignment of the cartridge-side ports relative to the device-side ports and reduces the poor continuity between the cartridge-side ports and the device-side ports. If the cartridge falls, the first cartridge-side restricting portion prevents the cartridge-side ports, for example, from hitting the ground surface directly, thus helping to protect the cartridge-side ports from damage. Especially when the cartridge-side terminals are mounted on the board with a storage unit, this protects the vulnerable storage unit from damage and increases the effect of impact resistance. The provision of the first cartridge-side restricting portion at the position close to the cut part makes it possible to arrange the lever of the cartridge mounting structure at the position closer to the first surface. This enables size reduction of the cartridge and the printer in the Z-axis direction.

Second aspect:

The cartridge according to the first aspect, wherein the first cartridge-side restricting portion is provided at a predetermined position close to a cut part where the third surface intersects the slanted surface.

In the cartridge according to the second aspect, the first cartridge-side restricting portion is provided at the specific position close to the cut part. The cartridge can therefore be attached to the cartridge attachment structure at the position close to the contact between the cartridge side ports and the device side ports. The first cartridge-side restricting portion prevents the misalignment of the cartridge-side terminals relative to the apparatus-side terminals. Therefore, the first cartridge-side restricting portion reduces the likelihood of poor continuity between the cartridge-side terminals and the apparatus-side terminals. If the cartridge falls, the first cartridge-side restricting portion reduces the likelihood that the cartridge-side ports, for example on the ground surface, will strike directly, thereby helping to protect the cartridge-side ports from damage. Especially when the cartridge-side terminals are mounted on the board with a storage unit, this protects the vulnerable storage unit from damage and increases the effect of impact resistance. When the first cartridge-side restricting portion is formed as a protrusion, the effects of impact resistance are further increased. The provision of the first cartridge-side restricting portion at the position close to the cut part enables the To arrange the lever of the cartridge attachment structure at the position closer to the first surface. This enables size reduction of the cartridge and the printer in the Z-axis direction.

Third aspect:

The cartridge according to the first aspect and / or the second aspect, wherein the first cartridge-side restricting portion is provided at a position intersecting a plane (plane Yc) passing through a center of a width or the Y-axis direction length of the cartridge and in parallel to the Z axis and the X axis.

When the cartridge is in a state attached to the printer, the cartridge receives a force from the jig-side terminals in a direction including a + Z-axis direction component, and the first cartridge-side restricting portion is pressed by this force against the first jig-side restricting portion of the lever , By providing the first cartridge-side restricting portion at a position intersected by the plane Yc, the portion of the first cartridge-side restricting portion near the position cut by the plane Yc would hardly move even if the cartridge is exerted by exerting an external force about the X-axis or move the z-axis. It should be noted that the first cartridge-side restricting portion is disposed at a position close to the cutting portion, the edge of the board, or both. By providing the first cartridge-side restricting portion which hardly moves at a position extremely close to the cartridge-side ports, the electrical connection between the cartridge-side ports and the device-side ports can be stable.

Fourth aspect:

The fourth aspect is the above-described embodiment in which the cartridge-side terminals include: a first terminal including a first outer part disposed at the outermost end in the + Y-axis direction; and a second terminal including a second outer part disposed at the outermost end in the -Y axis direction, wherein at least a part of the first cartridge-side restricting portion is disposed between the first outer part and the second outer part in the Y-axis direction, and For example, as discussed above, it may be implemented independently of, or in conjunction with, the above-described embodiments of the first aspect discussed above.

In the cartridge according to the fourth aspect, at least a part of the first cartridge-side restricting portion is disposed between the first outer part and the second outer part. This places the first cartridge-side restricted portion with little movement at the position very close to the cartridge-side terminals, thereby ensuring the stable electrical connection between the cartridge-side terminals and the contact mechanism.

Fifth aspect:

The cartridge according to the fourth aspect, wherein the first cartridge-side restricting portion is disposed not outside but within a range between the first outer part and the second outer part in the Y-axis direction.

Some of the jig-side ports may protrude further outward than the others. In the in 31 example shown is the connection 731 further outward. When the cartridge is mounted inside the printer, the cartridge-side ports receive force from the device-side ports with a + Z-axis direction component. If the cartridge is held too tight, contact with some of the device-side ports (port 734 in the example of 31 ) not be correct. By disposing the first cartridge-side restricting portion completely on the inner side of the terminals in the width direction, the cartridge may incline sufficiently to adjust the direction in which the inclined surface faces, so that the electrical connection between the cartridge-side terminals and the apparatus-side terminals even can be more stable. These advantages are also relevant to the constructions of the above-mentioned embodiments.

Sixth aspect:

The cartridge according to any one of the first to fifth aspects, further comprising a second cartridge-side restricting portion adapted to be detected by a second apparatus-side restricting member provided on the second apparatus-side side wall member and thereby to move the cartridge in the + Z-axis direction restrict, wherein the second cartridge-side restriction portion is provided on the fourth surface.

The cartridge according to the sixth aspect has the second cartridge-side restricting portion on the fourth surface to restrict the movement of the cartridge in the + Z-axis direction so as to control the movement of the cartridge in the + Z axis direction from both the + X axis direction end and the -X axis direction end. This further prevents the erroneous positional alignment of the respective cartridge side ports relative to the cartridge mounting structure and further ensures the stable electrical connection between the cartridge side ports and the device side ports.

Seventh aspect:

The cartridge according to the sixth aspect, wherein the second cartridge side restricting portion is a projection to be inserted into the second apparatus side restricting member formed as a recess or a through hole.

In the cartridge according to the seventh aspect, inserting the second cartridge-side restricting portion into the second apparatus-side restricting member provides the rotation fulcrum for rotating the cartridge by the vicinity of the second cartridge-side restricting portion. This facilitates the attachment of the cartridge to the cartridge attachment structure and removal of the cartridge from it.

Eighth aspect:

The cartridge according to any one of the first to seventh aspects, wherein the first cartridge-side restricting portion is disposed on the -X-axis direction side of the rotational axis of the lever.

In the cartridge according to the eighth aspect in the attached state, the first cartridge-side restricting portion generates a torque on the lever to turn the lever about the rotational axis of the lever in the direction opposite to the releasing direction. This reduces the likelihood that the first cartridge side restricting portion will be released from the first apparatus side restricting member, and further ensures the stable electrical connection between the cartridge side terminals and the apparatus side terminals. Even if the cartridge receives the force in the -X-axis direction from the jig-side terminals to move in the -X-axis direction, the first jig-side restriction member moves in the -X-axis direction with the movement of the cartridge. Such movement reduces the likelihood that the first cartridge side restricting portion will be released from the first apparatus side restricting member.

Ninth aspect:

The cartridge according to the eighth aspect, wherein the first cartridge-side restricting portion comprises: a first abutment member abutting against a first portion of the first apparatus-side restricting member to restrict movement of the cartridge in the + Z-axis direction, and a second abutment member abuts a second portion of the first apparatus-side restricting member to restrict movement of the cartridge in the + X-axis direction.

In the cartridge according to the ninth aspect, the first cartridge-side restricting portion has the first abutment part and the second abutment part, and therefore guarantees the generation of the torque on the lever to turn the lever about the rotational axis of the lever in the direction opposite to the releasing direction. This further reduces the likelihood that the first cartridge side restricting portion will be released from the first apparatus side restricting member, and more effectively prevents the poor continuity between the cartridge side terminals and the apparatus side terminals.

Tenth aspect:

The cartridge according to any one of the first to ninth aspects, further comprising a projection adapted to abut on the operating member of the lever and a force including the + Z-axis direction component during detachment of the cartridge attached to the cartridge attachment structure Receiving a cartridge attachment structure, wherein the projection on the + Z-axis direction side of the first cartridge-side restriction portion is provided on the third surface.

The cartridge according to the tenth aspect further comprises the projection. The cartridge can be easily detached from the cartridge attachment structure by use of the lever and projection actuator.

Eleventh aspect:

The cartridge according to any of the first to tenth aspects, wherein the corner portion has a step extending from the first surface in the + Z-axis direction, the step is disposed on the -X-axis direction side and -Z-axis direction side of the tapered surface, and the stage has a third cartridge side restricting member contacting with a third apparatus side restricting member the cartridge attachment structure is provided so as to restrict movement of the cartridge in the Y-axis direction.

In the cartridge according to the eleventh aspect, the third cartridge-side restricting member for restricting the movement of the cartridge in the Y-axis direction is provided at the corner portion with the cartridge-side ports. This restricts the movement of the side of the cartridge of the third surface in the Y-axis direction in the attached state of the cartridge.

Twelfth aspect:

The cartridge according to the eleventh aspect, wherein the third cartridge-side restricting member includes a pair of protrusion members adapted to receive the third apparatus-side restricting member projecting from the apparatus-side lower wall member in the + Z-axis direction, the pair of protrusion members being of the Stage protrudes in the + X-axis direction.

In the cartridge according to the twelfth aspect, the simple structure of providing the pair of protrusion elements projecting from the step in the + X-axis direction effectively restricts the movement of the side of the cartridge of the third surface in the Y-axis direction in the attached state Cartridge.

Thirteenth aspect:

The cartridge according to the eleventh aspect or the twelfth aspect, wherein a part of the third cartridge-side restricting member overlaps the slanted surface when the cartridge is viewed from the side of the first surface in the + Z-axis direction. In the cartridge according to the thirteenth aspect, the third cartridge-side restricting member and the slanted surface are arranged to partially overlap each other. This further restricts the movement of the side of the cartridge of the third surface in the Y-axis direction around the printing material supply tube.

Fourteenth aspect:

The cartridge according to any one of the first to thirteenth aspects, wherein the ink supply structure is provided at a predetermined position on the first surface closer to the fourth surface than to the third surface.

The cartridge according to the fourteenth aspect has the ink supply structure located closer to the fourth surface than to the third surface. This structure reduces the likelihood of sticking of the printing material to the cartridge-side terminals as compared with the structure in which the ink-feeding structure is located closer to the third surface than to the fourth surface. This reduces the poor continuity between the cartridge-side ports and the device-side ports.

Fifteenth aspect:

The cartridge according to any one of the first to fourteenth aspects, wherein the first cartridge-side restricting portion is a projection.

The cartridge according to the fifteenth aspect provides the first cartridge side restricting portion as a protrusion that may be small in size and simple in structure.

Sixteenth aspect:

The cartridge according to any one of the first to fifteenth aspects, wherein the cartridge-side ports include a cartridge side ground terminal in contact with a device side ground terminal of the device side terminal connected to a ground line, and the cartridge side ground terminal at a width center the Y-axis directional length of the cartridge is provided and adapted to contact the device side ground terminal before another cartridge side terminal in the course of mounting the cartridge on the cartridge attachment structure is in contact with a corresponding device side terminal.

In the cartridge according to the sixteenth aspect, the force first applied to the cartridge-side terminals by the cartridge attachment structure is generated at substantially the middle of the width or the Y-axis direction length of the cartridge. This prevents the force applied to the cartridge-side terminals from acting to tilt the cartridge in the Y-axis direction, thereby ensuring a stable electrical connection between the cartridge-side terminals and the device-side terminals. The cartridge-side grounding terminals contact the corresponding device-side grounding terminals before contacting the other cartridge-side terminals with the corresponding device-side terminals. The earthing function of the cartridge side ground terminal advantageously prevents or reduces the problems and disturbances caused by high voltage even when an unexpected high voltage is applied to the cartridge.

Seventeenth aspect:

The cartridge according to the sixteenth aspect, wherein a Z-axis direction length of the cartridge-side ground terminal is larger than the Z-axis direction length of the other cartridge-side terminal.

In this embodiment, the plurality of the holder 60 attached cartridges 20 in the direction along the Y-axis (left-to-right or side-to-side direction) referred to as the "Y-axis direction". Similarly, the direction along the X-axis (front-to-rear direction) and the direction along the Z-axis (vertical direction) are referred to as the "X-axis direction" and the "Z-axis direction".

A-2. Structure for attaching the cartridge 20 on the holder 60

2 and 3 are perspective views showing the holder 60 with the cartridge attached to it 20 illustrate. 4 is a plan view of the holder 60 with the cartridge attached to it 20 illustrated. In the in the 2 to 4 illustrated state is a cartridge 20 suitable at an intended mounting position of the holder 60 appropriate. The condition of "suitable attachment to an intended attachment position" and an "attached" position means that the cartridge 20 is attached or, in other words, inserted, that the cartridge-side terminals are arranged at positions respectively in contact with corresponding device-side terminals, in a contact mechanism of the printer 50 (described later) are included.

As in the 2 and 3 is shown, the holder points 60 of the printer 50 five wall elements 601 . 603 . 604 . 605 and 606 on. A recess formed by these five wall members serves as a cartridge chamber or cartridge mounting structure 602 , The patron chamber 602 is through partitions 607 in several slots (attachment spaces) for receiving the respective cartridges 20 separated. The partitions 607 serve as guides for inserting the cartridges 20 into the respective slots, but these can be omitted as appropriate. Each slot has a print material delivery tube 640 , a contact mechanism 70 , a lever 80 , a second device side restricting element 620 and a lead 636 acting as a third device-side restriction member. One side surface (+ Z-axis direction side surface, upper surface) of each slot is open and the cartridge 20 gets through this open side surface (open top surface) on the holder 60 attached and removed from this.

The bullet 20 will be in such a condition on the holder 60 attached that cartridge 20 through the lever 80 and the second device side restricting element 620 and the ink supply structure (described later) with the printing material supply tube 640 connected is. This condition is called "mounted condition of the cartridge 20 on the holder 60 , Simply "attached" state or alternatively "inserted" state. Connecting the print material supply tube 640 with the ink supply structure of the cartridge 20 allows it in the cartridge 20 as the printing material contained ink the head 540 to feed ( 1 ). The print material feed tube 640 has a circumferential end 642 (also referred to as "connection end") disposed on the + Z-axis direction side and a base end disposed on the -Z axis direction side 645 on. The base end 645 is on the lower wall element 601 provided and the perimeter end 642 is with the ink supply structure of the cartridge 20 connected. The print material feed tube 640 has a central axis C running parallel to the Z-axis. The along the central axis C from the base end 645 to the perimeter end 642 extending direction is the + Z-axis direction.

As in 2 is shown is an elastic element 648 around the printing material feed tube 640 provided around the periphery of the Tintenzuführstruktur the cartridge 20 in the attached state so as to prevent leakage of ink from the ink supply structure to the periphery. In the attached state exercises the elastic element 648 a pressing force including a + Z axis direction component on the cartridge 20 out.

In the attached (inserted) state allows an electrical connection between the on a board (described later) of the cartridge 20 provided connections and those of the contact mechanism 70 in each slot of the holder 60 a transfer of various information between the cartridge 20 and the printer 50 ,

5 is a sectional view taken along the line F4-F4 of 4 , The lead 636 is omitted from the illustration. The print material feed tube 640 of the printer 50 is so with an ink feed structure 280 the cartridge 20 connected that Ink through a printed material flow path 282 from the cartridge 20 to the head 540 ( 1 ) is supplied.

According to this embodiment, a porous filter 644 that serves to remove the from the cartridge 20 to feed supplied ink, at the peripheral end 642 the printing material supply tube 640 intended. The porous filter 644 For example, it can consist of a stainless steel grid or a stainless steel mesh. According to another embodiment, the porous filter may not be at the peripheral end 642 the printing material supply tube 640 be arranged.

The contact mechanism 70 of the printer 50 is at the + X axis direction side of the print material feed tube 640 arranged and set up with the on a circuit board 40 the cartridge 20 provided terminals to be electrically connected. In the attached state of the cartridge 20 becomes a pressing force Pt including a + Z-axis direction vector component from the terminals of the contact mechanism 70 on the board 40 exercised. In the attached state of the cartridge 20 becomes a pressing force Ps in the + Z-axis direction of the elastic member 648 to the ink supply structure 280 exercised.

One for attaching and removing the cartridge 20 used lever 80 has an actuator 830 at a + Z-axis direction end and an engaging portion 810 at an -Z axis direction end. The first apparatus-side restricting member or the engaging portion 810 (More specifically, the first apparatus-side locking surface described later) is arranged to have a first cartridge-side restricting portion 210 at a first locking position 810L to be engaged in the attached state. The first locking position 810L is on the + Z axis direction side and on the + X axis direction side of the contact between those on the board 40 provided connections and the contact mechanism 70 arranged. The engaging section 810 comes with the first cartridge-side restriction section 210 engaged to the movement of the cartridge 20 in the + Z axis direction.

The lever 80 turns around an axis 800c at the position between the actuator 830 and the engaging portion 810 , The rotation axis 800c of the lever 80 is at the + Z axis direction side and at the + X axis direction side of the first lock position 810L arranged.

The user uses the actuator 830 of the lever 80 to the cartridge 20 from the holder 60 to decrease. To remove the cartridge 20 the user presses the actuator 830 in the -X axis direction. This pressing applies a force Pr (referred to as "operating force Pr") from the + X-axis direction side toward the -X-axis direction side to the operating member 830 out. This actuating force Pr turns the lever 80 around the axis 800c and moves the engaging portion 810 from the first locking position 810L in the + X-axis direction. This releases the engagement of the first cartridge-side restricting portion 210 with the engaging portion 810 and allows the cartridge 20 from the holder 60 to decrease.

The second device-side restricting element 620 is on the sidewall element 604 provided and arranged for, with a second cartridge-side restriction section 220 at a second locking position 620L to get in touch. According to this embodiment, the second device side restricting element 620 one in the side wall element 604 of the owner 60 trained passage opening. The second locking position 620 is on the + Z axis direction side and on the -X axis direction side of the printing material feed tube 640 arranged. The second device-side restricting element 620 comes with the second cartridge-side restriction section 220 (also as the second constraint element 220 can be designated) in engagement with the movement of the cartridge 20 in the + Z axis direction. As described above, the movement of the cartridge 20 in the + Z axis direction in the attached state by both its + X axis direction end and its -X axis direction end.

The second locking position 620L at which the second cartridge-side restricting section 220 with the second device-side restriction element 620 Being in contact serves as a fulcrum to the cartridge 20 is turned to the holder 60 be attached and removed from this. In other words, the cartridge 20 around the second locking position 620L is rotated along a parallel to the Z-axis and the X-axis extending plane for attachment or detachment. The second cartridge-side restriction element 220 and the second device side restricting element 620 Accordingly, they serve as the pivot point of rotation of the cartridge 20 for attaching or removing the cartridge 20 , Attaching the cartridge 20 on the holder 60 and removing the cartridge 20 this will be described in detail later.

As in 5 is shown, in the attached state, the first locking position 810L with a distance Dz from the second locking position 620L arranged at the -Z axis direction side. This reduces the likelihood that the first cartridge-side restricting section 210 through the holder 60 on the cartridge 20 exerted Pressing forces Ps and Pt from the engaging portion 810 is solved. The cartridges 20 can therefore be stably held at the intended mounting position.

The 6A and 6B illustrate one at the first locking position 810L from the cartridge 20 on the lever 80 applied force. In the state of 6A in which the first locking position 810L at the -Z axis direction side of the second lock position 620L is arranged, a force F1 at the first locking position 810L from the cartridge 20 on the lever 80 exercised. In the state of 6B in which the first locking position 810L at the + Z-axis direction side of the second lock position 620L is arranged, a force F2 at the first locking position 810L from the cartridge 20 on the lever 80 exercised. The in the 6A shown force F1 has the same size as that in the 6B shown force F2.

The 6A and 6B show schematically the positional relationships of the first locking position 810L , the second locking position 620L and the axis of rotation 800c (also called "Drehzentrum 800c ") To each other on the X-axis and the Z-axis. The difference between those in the 6A and 6B shown two positional relationships is the difference of the second locking position 620L on the Z axis. One in the 6A and 6B arc shown RT1 shows the rotation locus of the first lock position 810L around the axis of rotation 800c , One in the 6A and 6B Arc shown RT2 shows the rotation locus of the first lock position 810L around the second locking position 620L ,

In the in the 6A illustrated example is the first locking position 810L at the -Z axis direction side of the second lock position 620L arranged so that the force F1, which is in the tangential direction of the arc RT2 at the first locking position 810L is applied, has a + X-axis direction vector component and a + Z-axis direction vector component. Accordingly, the force F1 is decomposed into a vector component Fit in the tangential direction of the arc RT1 and a vector component F1r in the radial direction of the arc RT1.

In the in the 6B illustrated example is the first locking position 810L at the + Z-axis direction side of the second lock position 620L arranged so that the force F2 acting in the tangential direction of the arc RT2 at the first locking position 810L is applied, has an -X axis direction vector component and a + Z axis direction vector component. Accordingly, the force F2 is decomposed into a vector component F2t in the tangential direction of the arc RT1 and a vector component F2r in the radial direction of the arc RT1.

How clear from the comparison between the 6A and 6B is apparent, when the magnitude of the force F1 is equal to the magnitude of the force F2 (F1 = F2), the positional relationships of the first detection position 810L , the second locking position 620L and the axis of rotation 800c to each other, "F1t <F2t" for the vector component in the tangential direction of the arc RT1 and "F1r>F2r" for the vector component in the radial direction of the arc RT1. Compared with the 6B illustrated state, the state in the 6A a larger force vector component from the cartridge 20 in the direction of the axis of rotation 800c of the lever 80 and a smaller force vector component in the direction of the lever 80 Turning clockwise, that is viewed from the + Y-axis direction about the axis of rotation 800c , on. In other words, arranging the first locking position decreases 810L at the -Z axis direction side of the second lock position 620L compared with arranging the first detection position 810L at the + Z-axis direction side of the second lock position 620L more effectively the probability that the first cartridge-side restricting section 210 from the engaging portion 810 is solved. In both states, no force acts in the + X axis direction to engage the first lock position 810L so that both states provide an advantage in reducing the likelihood that the first cartridge-side constraint section 210 from the engaging portion 810 is solved.

A-3. Accurate structure of the cartridge

7 is a perspective view showing the structure of the cartridge 20 as an example of a cartridge according to an embodiment of the invention. 8th is a bottom view of the cartridge 20 , 9 is a sectional view taken along the line F8-F8 in 8th , 10A and 10B illustrate the exact structure of the board 40 , 10A is a view of the board 40 from the arrow F9 in 9 viewed from the direction and 10B is a view of the board 40 from the arrow F10 in FIG 10A out of view. According to this embodiment, the X-axis, the Y-axis and the Z-axis set the axes on the cartridge 20 in the attached state. The + X-axis direction side in the attached state is the front surface of the cartridge 20 , One in the 8th Plane Yc shown is a plane through the center of the width or Y-axis direction length of the cartridge 20 is parallel to the Z-axis and the X-axis (that is, the ZX plane). One in the 8th level CX shown is a level through the central axis C is parallel to the Z-axis and the X-axis (that is, the ZX plane).

Like in the 7 shown includes the cartridge 20 an ink chamber containing ink 200 , a housing 22 , the ink supply structure 280 , the circuit board 40 and the first cartridge-side restricting section 210 , The bullet 20 becomes in a mounting direction SD, which is the -Z-axis direction (the vertically downward direction in the embodiment), on the holder 60 appropriate. The specific orientation or position of the cartridge 20 is usually not constant during the actual insertion of the cartridge 20 in the holder 60 , In the course of attaching the cartridge 20 on the holder 60 can the cartridge 20 inclined with respect to the Z-axis. In the state immediately before mounting and in the attached state, the ink supply structure increases 280 however, the printing material supply tube 640 on whose central axis C is parallel to the Z axis, so that the particular orientation of the cartridge 20 through the printing material feed tube 640 is restricted and thus aligned substantially in the Z-axis direction. For this reason and there the general direction of movement of the cartridge 20 while these in the holder 60 is used in the -Z-axis direction, the -Z-axis direction as the mounting direction of the cartridge 20 be considered. For the same reasons, the + Z axis direction may be referred to as a removal direction RD (FIG. 9 ) in which the cartridge 20 from the holder 60 is removed. Since the -Z axis direction and the + Z axis direction are opposite directions, the attachment direction SD and the removal direction RD can be considered to be opposite directions.

The housing 22 (Also called "cartridge body 22 "Defines) defines an internal space that the ink chamber 200 the cartridge 20 includes. The housing 22 also forms at least part of the outer wall surfaces of the cartridge 20 and may be made of a synthetic resin such as polypropylene (PP). The bullet 20 has a rectangular prism shape with congruent side surfaces or an approximately rectangular parallelepiped shape. Part of the housing 22 can consist of a resin film.

The bullet 20 has a length (X-axis direction length), a width (Y-axis direction length) and a height (Z-axis direction length), and the length, height and width decrease in this order. The size relationship of the length, the width and the height of the cartridge 20 but is not limited to this order, but can be freely determined; For example, the height, length, and width may decrease in this order, or the height, length, and width may be equal.

The first to eighth walls 201 to 208 define the inner space of the ink chamber 200 the cartridge 20 includes. In the following description, the characters associated with the first to eighth walls will be used 201 to 208 also used the outer surfaces of the housing 22 the cartridge 20 represent forming walls (that is, first to eighth surfaces 201 to 208 ). The outer surfaces (first to eighth surfaces) 201 to 208 The first to eighth walls are essentially levels. The term "substantially one plane" not only means a perfectly flat plane, but may include a plane with a partial slight irregularity. In other words, the term "substantially a plane" includes a plane that has a partial slight irregularity but still as a face or wall of the housing 22 the cartridge 20 is recognizable. The first to eighth surfaces 201 to 208 have rectangular shapes in plan view. The first surface (first wall) 201 , the second surface (second wall) 202 , the third surface (third wall) 203 , the fourth area (fourth wall) 204 , the fifth area (fifth wall) 205 and the sixth surface (sixth wall) 206 are each also called lower surface (lower wall) 201 , upper surface (upper wall) 202 , front surface (front wall) 203 , rear surface (back wall) 204 , left side surface (left wall) 205 and right side surface (right wall) 206 designated. The outer surfaces of the walls can also be considered the front 203 , the backside 204 , the upper end 202 and the bottom end 201 or as first to fourth surfaces, the first surface being the front side 203 The second surface is the backside 204 The third surface is the upper end 202 and the fourth surface is the lower end 201 designated.

The first area 201 and the second surface 202 face each other in the Z-axis direction. The first area 201 is located on the -Z axis direction side, while the second surface 202 is arranged on the + Z-axis direction side. The third area 203 and the fourth area 204 face each other in the X-axis direction. The third area 203 is located on the + X-axis direction side, while the fourth surface 204 is arranged at the -X-axis direction side. The fifth area 205 and the sixth area 206 face each other in the Y-axis direction. The fifth area 205 is located on the + Y axis direction side, while the sixth surface 206 is arranged on the -Y axis direction side.

According to this embodiment, the first surface disposed on the -Z axis-direction side forms 201 in the attached state, the lower surface. The first area 201 is an XY plane parallel to the X-axis and the Y-axis and perpendicular to the Z-axis. The first area 201 is a horizontal surface in the attached state.

The second surface located on the + Z-axis direction side 202 forms in the attached state, the upper surface. The second area 202 lies the first surface 201 opposite and lies parallel to the first surface 201 , The second area 202 is a plane parallel to the X axis and the Y axis and perpendicular to the Z axis (XY plane). The second area 202 is a horizontal surface in the attached state.

The third surface located on the + X-axis direction side 203 forms in the attached state a side surface. The third area 203 is perpendicular to the first surface 201 and the second surface 202 and is a plane parallel to the Y-axis and the Z-axis and perpendicular to the X-axis (YZ-plane). From the sides of the third area 203 become an outermost -Z-axis direction side 290 as "first page 290 And an outermost + Z-axis direction side 291 as the "second page 291 " designated. In the description thereof, the expression that "two surfaces intersect or cross each other" denotes not only the state that two surfaces actually intersect each other, but the state that one extension of one surface intersects the other surface, and the state that extensions of two Surfaces intersect each other.

The fourth surface located on the -X-axis direction side 204 forms in the attached or inserted state a side surface. The fourth area 204 is perpendicular to the first surface 201 and the second surface 202 , The fourth area 204 is parallel to the third surface 203 , The fourth area 204 is a plane parallel to the Y axis and the Z axis and perpendicular to the X axis (YZ plane).

The fifth surface located on the + Y-axis direction side 205 and the sixth surface located on the -Y axis direction side 206 form in the attached state side surfaces. The fifth area 205 and the sixth area 206 lie perpendicular to the first to fourth surfaces 201 to 204 , The fifth area 205 and the sixth area 206 are planes parallel to the X-axis and the Z-axis and planes perpendicular to the Y-axis (XZ planes). The sixth area 206 is parallel to the fifth surface 205 ,

As in 9 is shown, couple the connecting surfaces 209 the first area 201 with the third surface 203 , The seventh area 207 the connecting surfaces 209 is perpendicular to the first surface 201 and is a plane parallel to the Y-axis and the Z-axis (YZ-plane). The seventh area 207 is relative to the first surface 201 vertically angled and can also be referred to as a "step". In other words, the seventh surface extends 207 from the first surface 201 in the + Z-axis direction. The seventh area 207 is at the -X axis direction side and at the -Z axis direction side of the eighth surface 208 arranged. The eighth surface 208 couples the seventh surface 207 with the third surface 203 , The eighth surface 208 is a tapered surface inclined in a direction including a + X-axis direction vector component and a -Z axis direction vector component. The eighth surface 208 is to the first surface 201 and the third area 203 inclined. The eighth surface 208 is perpendicular to the fifth surface 205 and the sixth area 206 , In other words, the eighth surface 208 to the XY plane and the YZ plane inclined and perpendicular to the XZ plane. The eighth surface 208 has a board attachment element 208T on, that of the eighth surface 208 protrudes outwards.

The relationships of the first to sixth surfaces 201 to 206 indicate that the direction in which the first surface 201 and the second surface 202 which is Z-axis direction, the direction in which the third surface 203 and the fourth area 204 which is the X-axis direction and the direction in which the fifth surface 205 and the sixth area 206 which is Y-axis direction.

As in 7 shown is the board 40 preferably on the board attachment element 208T the eighth surface 208 appropriate. The board 40 has a connection carrier structure 408 on, like the eighth surface 208 in the direction including the + X-axis direction vector component and the -Z-axis direction vector component is inclined or, in other words, chamfered. In this embodiment, the terminal support structure comprises 408 the surface of the board 40 , The connection carrier structure 408 is to the first surface 201 and the third area 203 inclined. The connection carrier structure 408 is perpendicular to the fifth surface 205 and the sixth area 206 , In other words, the connection carrier structure 408 to the XY plane and the YZ plane inclined and perpendicular to the XZ plane. The connection carrier structure 408 is also called "beveled connection carrier structure" or " beveled surface ". Therefore, in the present embodiment, the surface of the board 40 be regarded as a "bevelled surface". The connection carrier structure 408 has cartridge-side connections 400 on, with the device-side terminals of the contact mechanism 70 ( 2 ) stay in contact. The angle of inclination is preferably between 0 degrees and 90 degrees, more preferably between 20 degrees and 50 degrees, and most preferably between approximately 25 degrees and 40 degrees.

42A and 42B show the relationship of a wiping amount of the terminal to the board 40 by a device-side connection with respect to a tilt angle phi of the board 40 , The inclination angle phi of the board 40 makes an angle between the plane 110p extending from the attachment direction leading edge of the ink delivery structure 280 extends, and a plane in which the connectors 400 the board 40 through the connections 400 defined plane is neither perpendicular nor parallel to the plane 110p , The inclination angle phi is usually an acute angle (less than 90 degrees). In this embodiment, the plane lies 110p which extends from the attachment direction leading edge, parallel to the lower surface 201 the cartridge 20 , In addition, the level lies in which the connections 400 are arranged, parallel to the board surface of the board 40 , Accordingly, in this embodiment, the inclination angle phi is equal to the angle between the lower surface 201 the cartridge 20 and the board surface of the board 40 , In the present embodiment, the board is 40 approximately 0.7 mm thick. The connections 400 are approximately 5 microns thick and on the board 40 intended. The thickness of the connections 400 is negligibly small, leaving the surface of the board 40 showing the surface of the connections 400 includes, is essentially flat. Therefore, the terminal support structure 408 in this embodiment, the surface of the board 40 substantially disposed within a terminal (contact portion) plane TP, which will be described later. Even if the board 40 would be missing, only one of the thickness of the connectors 400 corresponding unevenness exist. Therefore, for the sake of simplicity, the terminal support structure 408 can be used interchangeably with "plane defined by the ports" or "port plane". When in connection with the terminal support structure 408 on contact sections cp of the connections 431 - 439 Also, the terms "plane defined by the contact portions" or "contact portion plane" may be used interchangeably. In the course of attaching or inserting the cartridge 20 moves, as in the 24 - 27 shown is the front surface 203 (the first surface) of the cartridge 20 with a slight pivoting rotation on the rear surface 204 (the second surface) of the cartridge 20 downward. In this process, the board rotates 40 easy and comes with the device side contact formation elements (device side terminals) 731 - 739 at the connection base 709 in contact, so that the respective cartridge-side connections 431 - 439 through the device side contact formation elements 731 - 739 be wiped. Wiping the connector on the board 40 through the appropriate device-side connector suitably removes the dust or oxide coating on the surface of the connector on the board 40 so that the electrical conductivity (electrical connection) is increased.

The graphic representation of the 42A shows the wiping length (wiping amount) of the connection to the board 40 by the corresponding device side contact forming elements as the ordinate and the platinum inclination angle phi as the abscissa. The calculation is based on the assumption that the distance L0 in the X direction from the second surface (back surface) 204 the cartridge 20 to the contact portion of the ground terminal 437 connected to the corresponding device-side ground connection 737 comes in contact, 63 mm. In general, a larger platinum tilt angle phi causes the board surface to be closer to the vertical plane and increases the amount of wiping. To remove the dust or the oxide coating on the surface of the connector on the board 40 to sufficiently remove, the amount of wiping is preferably not less than 1 mm. According to the graph of 42A For example, the platinum inclination angle phi is preferably not less than 25 degrees to ensure the wiping amount of not less than 1 mm.

43A shows the relationship of the upward force F through the device side ground terminal 737 to the platinum inclination angle phi taking into consideration the prevention of half insertion of the cartridge. The calculation of 43A is based on the calculation of the 42A also on the assumption that the distance L0 is 63 mm. The weight of the cartridge (including the weight of the ink) is assumed to be 30 grams. This value is the standard weight of the cartridge for ink jet printing devices for use in a home. The "half insertion of the cartridge" refers to the state in which the engagement portion 810 of the lever 80 right next to the elastic element 682 is arranged as in the 25 is shown, that is the state immediately before the complete engagement. This half insertion condition is also referred to as "half engagement". In this state of half engagement, only the device-side ground terminal is exercised 737 from the several devices side Contact form elements 731 - 739 the upward force on the board 40 out. It should be noted that at the in 1 shown printing device of the holder 60 has no cover. If the user releases the hand in this state of half engagement, the cartridge may 20 be maintained in this state of half engagement. The graphic representation of the 43A shows the calculation result of the upward force through the device side ground terminal 737 to make such a half insertion of the cartridge 20 to prevent. The 43B shows the relationship of the upward force F to the platinum inclination angle phi.

The upward force through the device side ground connection 737 is a + Z-direction vector component (vertical-upward vector component in this embodiment) of the device-side ground terminal 737 on the board 40 (and the cartridge 20 ) in the state of half engagement of 26 applied force. If the ground connection 437 the board 40 against the device side ground connection 737 is pressed, a pressing force in a direction perpendicular to the board surface of the board 40 by the elastic force of the device side ground terminal 737 to the ground connection 437 exercised. The calculation of the upward force of the 43A is based on the assumption that a pressing force F0 of the device side ground terminal 737 in the direction perpendicular to the board surface is 0.2N. Since the upward force F (= F0 × cos phi) is the + Z-direction vector component of the pressing force F0, at the platinum inclination angle, phi = 0 degrees F = F0 = 0.2 N as indicated by the broken line in FIG 43B is shown. The upward force F changes according to the curve F = F0 × cos phi upon a change in the platinum inclination angle phi. The curve of 43A is the curve F = F0 × cos phi. As the platinum tilt angle phi (phi approaches 90 degrees) increases, the board surface approximates the XZ plane and the upward force F decreases. An upward force FB, which is the cartridge 20 with the distance L0 of 63 mm and the weight of 30 grams in equilibrium is approximately 0.15 N (the position of the thick horizontal line in FIG 43A ). This means that the upward force of not less than 0.15 N allows the cartridge 20 through the device side ground connection 737 is pushed vertically upwards. In order to ensure that the upward force is not less than 0.15 N, the platinum inclination angle phi is preferably not larger than 40 degrees, as is clear from FIG 43A is apparent.

When the user's hand in the state of half engagement of the 26 can solve the cartridge 20 be maintained in the state of half engagement. When the platinum inclination angle phi is set to not larger than 40 degrees, as in FIG 43A however, when the user releases the hand in the state of half engagement, the device side ground terminal presses 737 the front surface 203 the cartridge 20 in the + Z direction (upward direction). This clearly disengages the cartridge from the engagement portion 810 of the lever 80 and allows the user to determine the failed attachment. In this regard, it is preferable to set the platinum inclination angle phi to be not larger than 40 degrees.

44 and 45 show the characteristics of a cartridge that has a larger dimension in the x-direction than the dimension of the cartridge in the 42 and 43A having. While it is believed that the cartridge in the 42 and 43A The distance L0 = 63 mm is assumed to be the distance L0 = 80 mm in the 44 and 45 having. The calculation of the upward force of the 45 is based on the assumption that as in the calculation of 43A F0 = 0.2 N and the weight of the cartridge (including the weight of the ink) is 30 grams. How clear from the result of 44 is apparent, the platinum inclination angle phi is as in the result of 42A preferably, not less than 25 degrees to ensure the wiping amount of not less than 1 mm. Although in the calculation of 45 the distance L0 is 80 mm relative to 63 mm when calculating the 43A is the upward force FB which is the cartridge 20 with the weight of 30 grams in equilibrium, almost equal to that of the 43 and is approximately 0.15 N (the position of the thick horizontal line in FIG 45 ). How clear from the result of 45 is apparent, the platinum inclination angle phi is as in the result of 43A preferably not greater than 40 degrees to prevent half intervention of the cartridge.

Taking into account the properties discussed above 42 to 45 For example, it is preferable to set the platinum inclination angle phi to be not less than 25 degrees and not more than 40 degrees.

The increased pressure force of the device side ground connection 737 ensures the sufficient upward force even at the larger platinum tilt angle phi. In this case, it is preferable the pressing force of the device-side ground terminal 737 and adjust the platinum tilt angle phi to those values that allow the cartridge 20 by the pressing force of the device-side ground terminal 737 is pushed up and changes from the state of half engagement to the released state when the user in the state of half engagement, the hand of the cartridge 20 solves.

The seventh area 207 and the terminal support structure 408 form part of the outer surfaces of the cartridge 20 , More specifically, form the seventh surface 207 and the terminal support structure 408 a section of a corner section 265 who is the first surface 201 and the third area 203 forming part of the outer surfaces of the cartridge 20 form, couples. For a better understanding, the corner section 265 in the 9 shown by a thick line. The third area 203 and the corner section 265 lie the first device side sidewall element 603 of the owner 60 opposite in the state in which the cartridge 20 on the holder 60 appropriate ( 14 ), as will be described later. The third area 203 and the corner section 265 are therefore referred to as "first opposing outer wall surface". The fourth area 204 is the second device side sidewall element 604 of the owner 60 in the attached condition opposite ( 15 ), as will be described later. The fourth area 204 is therefore referred to as "second opposite outer wall surface".

The board 40 is through the hub groove 401 and the hub opening 402 on the eighth surface 208 the cartridge 20 attached. According to this embodiment, the keyway are 401 and the hub opening 402 provided at positions which are the plane Yc passing through the center of the width (Y-axis direction length) of the cartridge 20 runs, cut. According to a further embodiment, the keyway 401 and / or the hub opening 402 from the board 40 be omitted and the board 40 on the eighth surface 208 by an adhesive or one on the eighth surface 208 provided engagement pawl (not shown) may be attached.

As in the 10A and 10B shown includes the board 40 the cartridge-side connections 400 attached to the connection carrier structure 408 are provided, and one on a rear surface 409 provided memory unit 420 , The connection carrier structure 408 and the back surface 409 are levels. A section or side of the planar connection carrier structure 408 that in the state in which the board 40 at the cartridge 20 is mounted on the outermost + Z-axis direction side, is referred to as a board end 405 designated.

The cartridge-side connections 400 include nine ports 431 to 439 , The storage unit 420 stores information regarding the ink of the cartridge 20 (For example, the remaining amount of ink and the ink color). The cartridge-side connections 400 are electrically conductive and may be coupled to an electrical device that forms part of the cartridge 20 forms. As used herein, the electrical device may refer to a resistor, sensor, or storage device or other device that generates electricity or is powered by electricity, as will be understood by those skilled in the art.

Like in the 10A shown are the nine cartridge-side ports 431 to 439 all have an approximately rectangular shape and these are arranged in two rows, which are substantially perpendicular to the mounting direction SD. The substantially vertical rows extend in the width direction (Y-axis direction) of the cartridge 20 , The series of the two rows on the front side with respect to the attachment direction SD is referred to as the first terminal row R1 (lower row R1) and the row on the back side with respect to the attachment direction SD is referred to as the second terminal row R2 (upper row R2). The first terminal row R1 and the second terminal row R2 have different positions in the Z-axis direction. More specifically, the first terminal row R1 is disposed on the -Z axis direction side of the second terminal row R2. Each of the connections 431 to 439 has at its center on a contact portion cp, with the contact mechanism 70 in contact. The first terminal row R1 and the second terminal row R2 may be regarded as rows formed by a plurality of contact portions cp.

The connections 431 to 439 may be termed the following terms corresponding to their functions or applications. To distinguish it from the connectors on the printer 50 the term "cartridge-side" can be preceded by any name. For example, the "ground connection 437 As "cartridge-side ground connection 437 Be designated.

The contact sections cp of the connections 435 to 439 at the first terminal row R1 and the contact portions cp of the terminals 431 to 434 at the second terminal row R2 are arranged alternately or more specifically in a zigzag arrangement.

The four attachment detection connections 431 . 434 . 435 and 439 are used to make the good / bad electrical contact with the corresponding, in the contact mechanism 70 provided device-side connectors, so that the printer 50 can capture if the cartridge 20 suitable at the intended mounting position of the holder 60 is appropriate. These four connections 431 . 434 . 435 and 439 are collectively referred to as "attachment sense connections". According to this embodiment, the four cartridge-side ports 431 . 434 . 435 and 439 inside the board 40 electrically connected to each other. If the cartridge 20 on the holder 60 will be attached, these connections 431 . 434 . 435 and 439 through the ground connection 437 with a ground lead (not shown) on the printer 50 electrically connected. The method of detecting the attachment by using the four attachment detection terminals 431 . 434 . 435 and 439 will be described later.

The other five cartridge-side connectors 432 . 433 . 436 . 437 and 438 are connections for the storage unit 420 ,

These five connections 432 . 433 . 436 . 437 and 438 are therefore also referred to as "memory ports".

The reset port 432 receives a reset signal RST that the memory unit 420 is to be supplied. The clock connection 433 receives a clock signal SCK, that of the memory unit 320 is to be supplied. The power connection 436 receives a power supply voltage VDD (for example, a rated voltage of 3.3 V), that of the memory unit 420 is to be supplied.

The first connection 435 as one of the attachment detection terminals includes a first outer part 435P at the outermost + Y axis direction side of the cartridge side ports 400 is arranged. The second connection 439 as one of the attachment detection terminals includes a second outer part 439P at the outermost -Y axis direction side of the cartridge side ports 400 is arranged. The third connection 431 as one of the attachment detection terminals includes a third outer part 431P which is located at the outermost + Y-axis direction side of the second terminal line R. The fourth connection 434 as one of the attachment detection terminals includes a fourth outer part 434P which is located at the outermost -Y axis direction side of the second terminal line R. In this embodiment, the first to fourth outer parts 435P . 439P . 431P . 434P substantially straight edges of the respective terminals and extend substantially in the Z-axis direction, but this should not be considered as a limitation. For example, the edges could be curved and extend in a direction that is not parallel to the Z-axis direction, such as for the terminals 431 . 434 in the example of 41A and 41B and the outer part of the terminal could still be understood as the outermost portion of the edge in the Y-axis direction.

From the contact portions cp of the cartridge-side terminals 400 is the ground connection 437 having the contact portion cp at the center in the Y-axis direction, provided at the position which is the center of the width (Y-axis direction length) of the cartridge 20 extending plane Yc intersects. The contact sections cp of the other connections 431 to 436 . 438 and 439 are arranged to be relative to the intersection of the plane Yc and the ground terminal 437 as the axis are symmetrical. The ground connection 437 is set up with the contact mechanism 70 in the course of attaching the cartridge 20 on the holder 60 in front of the other cartridge-side connections 431 to 436 . 438 and 439 to be in contact. The first of the holder 60 on the board 40 Therefore, both before and after the cartridge is fully applied, the applied pressing force becomes substantially at the center of the width or Y-axis direction length of the cartridge 20 generated. This prevents the on the board 40 exerted compressive force acts so that it is the cartridge 20 in the Y-axis direction, thereby enabling the attachment of the cartridge 20 at the intended attachment position. Such a contact of the ground connection 437 with the contact mechanism 70 of the owner 60 in front of the other cartridge-side connections 431 to 436 . 438 and 439 prevented or reduced by the earthing function of the ground connection 437 advantageous by High voltage induced problems and disturbances, even if an unexpected high voltage to the cartridge 20 is created.

According to this embodiment, the ground terminal 437 formed along the Z-axis direction longer than the other cartridge-side ports 431 to 436 . 438 and 439 , This ensures the contact of the ground connection 437 with the contact mechanism 70 of the owner 60 , According to a further embodiment, all cartridge-side connections 431 to 439 on the board 40 be formed with the same size.

As in 9 is shown, the Tintenzuführstruktur stands 280 in the -Z axis direction from the first surface 201 out. The ink delivery structure 280 communicates with the ink chamber 200 through the printed material flow path 282 , The ink delivery structure 280 is with the print material supply tube 640 ( 5 ) of the printer 50 connected to those in the ink chamber 200 contained ink to the head 540 to feed ( 1 ). In other words, the ink supply structure is 280 open to the outside in the ink chamber 200 contained ink of the outside of the cartridge 20 supply. Again 5A can be seen, the ink supply structure 280 not from the first surface 201 protrude. Rather, in one embodiment, it may be flush or substantially flush with the first surface 201 be. In such an embodiment, the printing material delivery tube is 640 raised so that it lies close to the first surface when the cartridge 20 is appropriate.

The ink delivery structure 280 is at the position closer to the fourth surface 204 as to the third surface 203 on the first surface 201 intended. The distance between the outer surface of the ink supply structure 280 and the third area 203 in the X-axis direction is accordingly larger than the distance between the outer surface of the Tintenzuführstruktur 280 and the fourth surface 204 ,

The ink delivery structure 280 has an open peripheral end. The surface at this open perimeter end becomes an open surface 288 or alternatively referred to as a mounting direction leading edge and defines in the attached state a horizontal plane. That is, the open surface 288 is the front edge (XY plane) of the cartridge in the mounting direction SD and defines an XY axis plane which is parallel to the X-axis and the Y-axis.

A resin foam 284 is within the ink feed structure 280 at the position on the + Z-axis direction side of the open surface 288 or more specifically at the position in contact with the print material flow path 282 intended. According to this embodiment, before the transport of the cartridge 20 the open surface 288 the ink feed structure 280 sealed with a sealing member (not shown), such as a cap or foil. For attaching the cartridge 20 on the holder 60 becomes the sealing member (not shown) for sealing the open surface 288 from the cartridge 20 away.

According to this embodiment, the ink supply structure stands 280 in the -Z axis direction, with the center at the center axis C of the printing material supply tube 640 lies. According to another embodiment, the center of the ink supply structure 280 from the center axis C of the printing material supply tube 640 differ. According to this embodiment, the open surface is 288 the ink feed structure 280 viewed from the -Z-axis direction through the line-symmetric housing with respect to parallel to the X-axis and the Y-axis axes formed. According to a further embodiment, the open surface 288 the ink feed structure 280 be formed by the asymmetric housing and having a mounting direction leading edge defining a plane. The open surface 288 As viewed from the Z direction according to this embodiment, it has a rounded rectangular shape, but according to other embodiments, it may have any other suitable shape such as an accurate circle, an ellipse, an oval, a square, or a rectangle.

As in 9A is shown, the plane BP is a through the Anbringrichtungs leading edge of the open surface 288 the ink feed structure 280 educated level. The distance A is the distance between the plane BP and the engagement portion 212 of the first restriction section 210 , The distance B is the distance between the plane BP and an engagement portion of the second restriction member 220 , The distance C is the distance between the plane BP and the pivot point of the lever 80 around the axis 800c , Again 9A is to be taken, the distance B between the plane BP and an engagement portion of the second restriction member 220 greater than the distance A between the plane BP and the engagement portion 212 of the first restriction section 210 when measured in a direction perpendicular to the plane BP. The distance A between the plane BP and the engaging portion 212 of the first restriction section 210 is smaller than the distance C between the plane BP and the pivot point of the lever 80 around the axis 800c when measured in a direction perpendicular to the plane BP. In addition, like that 9A it can be seen, the plane TP through the beveled Anschlussträgerstruktur 408 formed Plane which in this embodiment is parallel to the tapered terminal support structure 408 itself, and therefore, for the sake of simplicity, may be the terminal support structure 408 used to refer to the TP level. The plane TP is neither parallel nor perpendicular to the plane BP. The connection carrier structure 408 has cartridge-side connections 400 on, with the device-side terminals of the contact mechanism 70 ( 2 ) stay in contact.

As in 7 is the first cartridge-side restriction section 210 at the third area 203 intended. The first cartridge-side restriction section 210 is at the + Z-axis direction side and at the + X-axis direction side of the ink supply structure 280 and the board 40 intended. The first cartridge-side restriction section 210 gets through the lever 80 ( 2 ), so that the movement of the cartridge 20 is limited in the attached state. The first cartridge-side restriction section 210 is as one of the third surface 203 built up in the + X-axis direction (outward) protruding projection. The first cartridge-side restriction section 210 is at the position closer to the first page 290 than to the second page 291 arranged along the Z-axis direction. According to this embodiment, the first cartridge-side restricting portion 210 next to the first page 290 arranged.

The first cartridge-side restriction section 210 includes a first section 212 which extends in the Y-axis direction (width direction), a second portion 214 moving in the + Z-axis direction (vertically upward direction) from the first section 212 extends, and a third section 215 moving in the -Z axis direction (vertical downward direction) from the first section 212 extends. As described above, the + Z-axis direction (vertically upward direction) is generally the removal direction RD and is opposite to the -Z-axis direction (vertically downward direction), which is generally the attachment direction SD. The first section or engagement section 212 acts with an engaging portion 810 of the lever 80 together to the movement of the cartridge 20 in the attached condition. The second section 214 is provided to the first section 212 through the expected part of the lever 80 when attaching the cartridge 20 on the holder 60 determine.

The first paragraph 212 includes a first cartridge-side detection surface 211 as a first abutment and a second cartridge-side detection surface 213 as a second appendage. The first cartridge-side detection surface 211 points in the + Z-axis direction. The second cartridge-side detection surface 213 points in the + X axis direction. The third section 215 stands with the first section 212 and the first page 290 in contact.

The bullet 20 further includes the at the fourth surface 204 provided second cartridge-side restriction section 220 , one on the third surface 203 provided projection 260 and one on the seventh surface 207 provided third cartridge-side restriction element 250 ,

The second cartridge-side restriction section 220 is as one of the fourth surface 204 constructed in the -X-axis protruding projection. The second cartridge-side restriction section 220 becomes the second device side restricting element 620 ( 3 ) in the shape of the through hole of the holder 60 introduced. The user turns the cartridge 20 when attaching the cartridge 20 on the holder 60 or removing the cartridge 20 from this to the second device-side restricting element 620 ( 3 ) inserted second cartridge side restriction section 220 , In other words, the second device-side restricting element is used 620 as the guide for attaching the cartridge 20 on the holder 60 or removing the cartridge 20 of this. This facilitates the attachment of the cartridge 20 on the holder 60 and removing the cartridge 20 of this. In the attached state of the cartridge 20 is the second cartridge-side restriction section 220 by the second device-side restricting element 620 noted the movement of the cartridge 20 in the attached condition. The second cartridge-side restriction section 220 is on the + Z axis direction side and on the -X axis direction side of the ink supply structure 280 and the board 40 arranged.

The lead 260 at the third area 203 is at the + Z-axis direction side of the first cartridge-side restricting portion 210 arranged. According to this embodiment, the projection 260 at the outermost + Z-axis direction position (uppermost position), which is the second side 291 at the third area 203 includes.

The third cartridge-side restriction element 250 is constructed as a pair of protrusion elements (restriction walls) extending from both Y-axis direction sides of the seventh surface 207 protruding in the + X axis direction. The pair of protrusion elements 250 takes the lead inserted in between 636 ( 2 ) and limited in cooperation with the projection 636 the movement of the cartridge 20 in the attached state in the Y-axis direction.

11 is a rear view of the cartridge 20 , The second cartridge-side restriction section 220 is related to 11 described in detail. The second cartridge-side restriction section 220 includes a restriction detection surface 222 as a restriction detecting element, a chamfered surface 224 , a first constraint face 226 and a second constraint side surface 228 ,

The restriction detection surface 222 points in the + Z-axis direction and forms a horizontal surface in the attached state. The restriction detection surface 222 is connected to the second device-side restricting element 620 ( 3 ) to serve as the fulcrum of rotation when the cartridge 20 is turned to from the holder 60 to be taken off.

The restriction detection surface 222 is through the second device-side restriction element 620 in the attached state, so as to determine the movement of the cartridge 20 in the attached state in the + Z-axis direction. The restriction detection surface 222 is provided at the position passing through the center of the width (y-axis direction length) of the cartridge 20 extending plane Yc intersects, and is perpendicular to this plane Yc. Like in the 5 is shown receiving the cartridge 20 in the attached state of the cartridge 20 the pressing forces Ps and Pt including the + Z-axis direction vector components from the holder 60 , The restriction detection surface 222 becomes due to these pressure forces Ps and Pt against the second device side restricting element 620 pressed. The second device-side restricting element 620 therefore stands with the restriction detection surface 222 in contact with the Y-axis direction. This reduces the likelihood that the cartridge 20 is tilted in the attached state about the X-axis.

The bevelled surface 224 is with the restriction detection surface 222 and inclined to the direction including the + Z axis direction vector component and the -X axis direction vector component. This allows the restriction detection surface 222 when attaching the cartridge 20 on the holder 60 easily to the second device side restricting element 620 to be led.

The first restriction side surface 226 forms a -Y axis direction side surface of the second cartridge side restricting portion 220 , The second constraint side surface 228 forms a + Y-axis direction side surface of the second cartridge-side restricting portion 220 , The first restriction side surface 226 is a plane pointing in the -Y axis direction and the second constraint side surface 228 is a plane pointing in the + Y-axis direction. The first restriction side surface 226 and the second constraint side surface 228 are planes that are parallel to the X-axis direction and the Z-axis direction, respectively. The first and second constraint faces 226 and 228 be through the second device-side restriction element 620 influences the movement of the cartridge 20 in the Y-axis direction in the attached state of the cartridge 20 to restrict.

12 is a front view of the cartridge 20 , The first cartridge-side restriction section 210 is related to 12 described in more detail. The first cartridge-side restriction section 210 is provided at the position intersecting the plane Yc. The first cartridge-side detection surface 211 is provided at the position intersecting the plane Yc and is perpendicular to this plane Yc.

The first cartridge-side detection surface 211 is not outside, but within a range 40Y between the first outer part 435P and the second outer part 439P arranged in the Y-axis direction (width direction) when the cartridge 20 from the side of the third surface 203 in the -X axis direction. According to this embodiment, the first cartridge-side restricting portion 210 , the first cartridge-side detection surface 211 includes, not outside but within the area 40Y arranged. In other words, the first cartridge-side restricting portion 210 arranged within a range passing through a first phantom line 435PL that the first outer part 435P includes, and a second phantom line 430PL that the second outer part 439P includes, is defined. The first phantom line 435PL and the second phantom line 439PL are straight lines that extend in the Z-axis direction. 13 is a left side view of the cartridge 20 , The positional relationship of the respective elements of the cartridge 20 is related to 13 described. A cutting area where the third area 203 the beveled Anschlussträgerstruktur 408 is called "cut part 295 " designated. According to the above description of the term "cut area", the cut area at which the third area includes 203 the beveled Anschlussträgerstruktur 408 cuts, not just the cutting area of the actual area 203 and the terminal support structure 408 , but also the intersection of one of the surface 203 and the terminal support structure 408 and an extension of the other of the area 203 and the connection carrier structure 408 or the intersection of extensions of the surface 203 and the terminal support structure 408 , The cut part 295 is a line parallel to the Y-axis direction. According to this embodiment, the cut part 295 arranged on a plane that extends from the third surface 203 extends in the -Z axis direction. The cut part 295 is accordingly at the -Z-axis direction side of the third surface 203 arranged. The midpoint in the Z-axis direction length on the third surface 203 (or more specifically, the midpoint between a section of the third surface 203 and the contact portion plane TP and the sectional area of the second surface 202 and the third area 203 ) becomes the center 203P designated.

The first cartridge-side restriction section 210 is close to the cut part 295 arranged. The first cartridge-side restriction section 210 can also be considered as next to the connection carrier structure 408 and close to the board end 405 be viewed arranged. This means that the first cartridge-side restricting section 210 sufficiently closer to the cartridge-side ports 400 or, more precisely, the section of the restriction section 210 which engages with the device side lever may be disposed at a position nearer to the contact portions cp than to a sectional area of the upper surface 202 and the front surface 203 , The first cartridge-side restriction section 210 is preferably at a certain part of the third surface 203 closer to the first page 290 than to the second page 291 or, more precisely, the section of the restriction section 210 which engages with the device side lever is at a position nearer to the cut part 295 as to a cutting area of the upper surface 202 and the front surface 203 that are in the area of the center 203P to the first page 290 lies, arranged. It is particularly preferred to use the first cartridge-side restricting section 210 at the position sufficiently close or close to the first page 290 provided. As used herein, "close to" may mean "close to,""near" or "to." As described above, the portion of the restriction portion is 210 which engages with the device side lever, at a position closer to the cut part 295 and / or the contact portions cp as a sectional area of the upper surface 202 and the front surface 203 arranged. Although in this embodiment, the sectional area of the upper surface 202 and the front surface 203 in the 13 by 291 As indicated above, as discussed above, the intersection region need not be where two surfaces actually cross each other, but could be where one surface intersects an extension of the other surface or where extensions of two surfaces intersect each other, such as through one dashed line in the embodiments of 35A and 35D is displayed. In this embodiment, the distance between a cutting area of the third surface 203 and the contact portion plane TP and the sectional area of the second surface 202 and the third area 203 approximately 20 mm. The distance between the first cartridge-side detection surface 211 the first cartridge side restriction section 210 and the intersection of the second surface 202 and the third area 203 is approximately 16 mm.

The effective part of the first cartridge side restriction section 210 , which specifically serves the position of the cartridge side ports 400 restrict is the first cartridge-side detection surface 211 , It is therefore preferred that the first cartridge-side detection surface 211 as close as possible to the cartridge-side connections 400 to arrange. An omission of the third section 215 the first cartridge side restriction section 210 and arranging the first section 212 in contact with the first page 290 allows the first cartridge-side detection surface 211 closer to the cut part 295 or the end of the board 405 lies.

Each of the printing material supply tubes 640 and each of the contact mechanisms 70 which include the device-side terminals are on the wall element 601 arranged in the X-axis direction. The print material feed tube 640 is on the side of the wall element 604 arranged and the contact mechanism 70 is on the side of the wall element 603 arranged. In other words, the printing material supply tube is 640 at the position closer to the wall element 604 as to the wall element 603 intended. The contact mechanism 70 is at the position closer to the wall element 603 as to the printing material feed tube 640 intended.

The elastic element 648 is on the wall element 601 around the printing material feed tube 640 provided around. As above with respect to 5 has been described seals the elastic element 648 the scope of the ink delivery structure 280 the cartridge 20 thereby preventing leakage of ink from the ink supply structure 280 to the extent in the state in which the cartridge 20 on the holder 60 is appropriate. The elastic element 648 generates the pressing force Ps in the direction of pushing back the ink supply structure 280 the cartridge 20 (in the + Z-axis direction) in the state in which the cartridge 20 on the holder 60 appropriate ( 5 ).

As in the 14 to 16 is shown, the holder points 60 an opening OP on the upper side opposite to the wall element 601 over the cartridge chamber 602 on. The bullet 20 passes through the opening OP when the cartridge 20 on the holder 60 attached or removed from this.

The wall element 603 is at the + X axis direction side of the wall element 601 relative to the wall element 601 vertically angled. According to this embodiment, the outermost + X-axis direction side of the wall member forms 603 an outer wall 603W , In the usage position of the printer 50 forms the outer wall 603W the front surface of the holder 60 , The outer wall 603W extends in the direction of the arrangement of the plurality of cartridges 20 (Y-axis direction). One for attaching and removing the cartridge 20 used lever 80 is on the wall element 603 intended. A lever 80 is in a movable manner or, more precisely, in a rotatable manner by a holder 690 on the wall element 603 attached. In other words, the lever 80 on the bracket 690 attached to a part of the wall element 603 forms. An axis of rotation of the lever 80 is parallel to the Y-axis direction.

If the user of this actuator 830 from the + X-axis direction side toward the -X-axis direction side (that is, when the user applies the operation force Pr to the operation member 830 exercise), the lever becomes 80 counterclockwise (viewed from the + Y axis direction) rotated about the axis of rotation. The lever 80 is accordingly rotated on the XZ plane parallel to the X-axis direction and the Z-axis direction.

The lever 80 is as one of the chamber forming wall elements 601 . 603 . 604 . 605 and 606 provided separate element. The lever 80 is made of a synthetic resin, special polyacetal (POM) according to this embodiment. The lever 80 has a degree of rigidity sufficient to the cartridge 20 determine. More specifically, the lever points 80 preferably a stiffness that does not significantly deform the lever 80 by one in the attached state of the cartridge 20 applied force (for example, a force of 14.4 N) causes. For example, it is preferable to deform the lever 80 by applying an external force of 14.4 N from the cartridge 20 not larger than approximately 0.5 mm. The lever 80 preferably has no elastically deformable portion. This reduces the likelihood that the lever 80 by in the attached state of the cartridge 20 from the cartridge 20 applied force is significantly deformed and ensures the stable electrical connection between the cartridge-side connections 400 and the device-side terminals of the contact mechanism 70 , The provision of the chamber forming wall elements 601 . 603 . 604 . 605 and 606 separate lever 80 advantageously increases the degree of freedom in the choice of the material of the lever 80 ,

Referring again to the 14 to 17 is the wall element 604 at the -X-axis direction side of the wall element 601 relative to the wall element 601 vertically angled. The wall element 604 lies the wall element 603 over the cartridge chamber 602 across from. According to this embodiment, the wall element forms 604 the back surface of the holder 60 in the usage position of the printer 50 , The wall element 604 extends in the direction of the arrangement of the plurality of cartridges 20 (Y-axis direction).

According to this embodiment, the second device side restricting element 620 is constructed as a through hole having the size around the second cartridge-side restricting portion 220 and has this a device-side detection surface 622 on. The device-side detection surface 622 is a plane facing in the -Z axis direction, and constitutes the restriction detection surface 222 the second cartridge side restriction section 220 firmly ( 11 ). A + X axis direction end 624 the device-side detection surface 622 stands with the second cartridge-side restriction section 220 in contact and accordingly serves as the fulcrum of rotation for removing the cartridge 20 from the holder 60 ,

Like in the 17 is shown, the second device side sidewall member 604 of the owner 60 one on the + Z-axis direction side of the second device side restricting element 620 provided space 670 on. The space 670 provides space for a rotation of the cartridge 20 around the vicinity of the second device side restricting element 620 as the pivot point of rotation to allow when the cartridge 20 on the holder 60 attached or removed from this. According to this embodiment, the space is 670 through from the second device side sidewall member 604 Steps recessed in the -X axis direction are stepped in the + Z-axis direction. According to another embodiment, the space 670 by a sloping surface of the wall element which is lowered in the -X-axis direction 604 be formed gradually in the + Z-axis direction.

As in the 14 to 16 is shown is the wall element 605 at the -Y axis direction side of the wall element 601 relative to the wall element 601 vertically angled. According to this embodiment, the wall element forms 605 the right side surface of the holder 60 in the usage position of the printer 50 , The wall element 605 is with the wall elements 603 and 604 connected. The wall element 605 extends in the X-axis direction and crosses the direction of the arrangement of the plurality of cartridges 20 (Y-axis direction).

The wall element 606 is at the + Y axis direction side of the wall element 601 relative to the wall element 601 vertically angled. The wall element 606 lies the wall element 605 over the cartridge chamber 602 across from. According to this embodiment, the wall element forms 606 the left side surface of the holder 60 in the usage position of the printer 50 , The wall element 606 is with the wall elements 603 and 604 connected. The wall element 606 extends in the X-axis direction and crosses the direction of the arrangement of the plurality of cartridges 20 (Y-axis direction).

A-4-2. Exact structure of the contact mechanism 70 :

18 is a perspective view of the contact mechanism 70 from the holder 60 is removed.

The contact mechanism 70 includes a connection base 709 and device side terminals or contact formation elements 731 to 739 at the connection base 709 are arranged. Each of the device-side connections 731 to 739 is an elastic member having electrical conductivity and has a tapered surface from a device side 708 projecting portion which is displaced by an external force. The device side connections 731 to 739 generate the pressing force or elastic force (pressing force) Pt in the direction of pushing back the board 40 the cartridge 20 (Direction including the + Z axis direction vector component and the -X axis direction vector component) in the state in which the cartridge 20 on the holder 60 appropriate ( 5 ). The elastic force (pressing force) Pt is generated as a reaction force when the cartridge 20 the from the device side beveled surface 708 protruding device-side connections 731 to 739 towards the device side beveled surface 708 suppressed. The resulting vector component is through the device side ports 731 to 739 generated elastic force Pt impinges the cartridge 20 in the removal direction RD which, as described above, is the direction opposite to the attachment direction SD.

The nine device-side connections 731 to 739 are at the nine cartridge-side ports 431 to 439 appropriate positions provided. The device side connection 731 is called "attachment detection port (third port) 731 " designated. The device side connection 732 is called "reset port 732 " designated. The device side connection 733 is called "clock connection 733 " designated. The device side connection 734 is called "attachment detection terminal (fourth terminal) 734 " designated. The device side connection 735 is called "attachment detection port (first port) 735 " designated. The device side connection 736 is called "power connection 736 " designated. The device side connection 737 is called "ground connection 737 " designated. The device side connection 738 is called "data port 738 " designated. The device side connection 739 is called "attachment detection terminal (second terminal) 739 " designated. To distinguish it from the cartridge-side connections, the term "device-side" can be preceded by any name. For example, the "ground connection 737 As "device side ground connection 737 Be designated. The nine device-side connections 731 to 739 become common as device-side ports 700 designated.

The nine device-side connections 731 to 739 are arranged in a first device-side terminal line and a second device-side terminal line with different positions in the Z-axis direction. The first device side connection line includes the five device side connections 735 to 739 and the second device side terminal line includes the four device side terminals 731 to 734 , The first device side terminal line is arranged on the -Z axis direction side of the second device side terminal line. The number of device side terminals is not limited to nine, but may be according to the structure of the board 40 be changed to any desired number greater than nine or less than nine.

From the nine device-side connections 731 to 739 is the device-side ground connection 737 which is disposed substantially at the center in the Y-axis direction, is electrically connected to a ground line (not shown). The protrusion height of the device-side ground terminal 737 from the device side beveled surface 708 is greater than the height of the other device-side ports 731 to 736 . 738 and 739 , The device-side ground connection 737 is accordingly in front of the other device-side connections 731 to 736 . 738 and 739 with the board 40 the cartridge 20 in contact.

According to this embodiment, the device side terminals 731 to 739 at the connection base 709 arranged and to the contact mechanism 70 united in the holder 60 is included to speed up the assembly of the printer. The united contact mechanism 70 who is the connection base 709 but is not essential. According to another embodiment, a suitable structure for receiving the device-side terminals 731 to 739 integral with the lower wall element 601 or the outer wall 603W of the owner 60 be formed and can the device side connections 731 to 739 in the structure be included. The connection base 709 is therefore not essential.

A-4-3. Accurate structure of the lever 80 :

19 is a perspective view showing the appearance of the lever 80 illustrated. 20 illustrates a cross section of a shaft body 850 lying on the plane parallel to the X-axis and the Z-axis (XZ-plane, plane perpendicular to the Y-axis). 21 illustrates a cross section of the lever 80 lying on the plane passing through the central area in the width direction (Y-axis direction) of the lever 80 is parallel to the X-axis and the Z-axis (XZ-plane, to the Y-axis vertical plane). The 21 shows the cross section of the lever 80 in the state in which the cartridge 20 suitable at the intended mounting position of the holder 60 is appropriate.

As in the 19 and 21 shown includes the lever 80 the actuator 830 , a pair of shaft bodies 850 , a guide element 820 and the engaging portion 810 , The lever 80 has the actuating element 830 at one end (+ Z-axis direction end) and the engaging portion 810 on the other side (-Z axis direction end). The lever 80 has an axis of rotation 800c between the actuator 830 and the engaging portion 810 on. In other words, the lever rotates 80 around the axis of rotation 800c at the position between the actuator 830 and the engaging portion 810 ,

The actuator 830 of the lever 80 receives the external force exerted by the user. Like in the 21 is shown is the actuator 830 at the + Z axis direction end of the lever 80 intended. The actuator 830 is in the state in which the cartridge 20 on the holder 60 is attached to the + Z-axis direction side of the rotation axis 800c arranged. The actuator 830 is at the + Z-axis direction side of the first apparatus-side side wall member 603 of the owner 60 arranged ( 15 ).

The actuator 830 has an actuating surface 835 and an opposite surface 831 of the actuating element. The actuating surface 835 receives by the user from the + X axis direction side to the -X axis direction side for detaching the cartridge 20 from the holder 60 exerted external force (which in 5 shown force Pr). The opposite surface 831 of the actuator is an area corresponding to the cartridge 20 in the state opposite to that in which the cartridge 20 on the holder 60 is appropriate.

Like in the 19 is shown is the pair of shaft bodies 850 essentially at the middle position between the ends of the lever 80 intended. The pair of shaft bodies 850 defines the axis of rotation 800c of the lever 80 , The rotation axis 800c is parallel to the Y-axis direction (direction of the arrangement of the cartridges 20 ). A shaft body 850a the pair of shaft bodies 850 (as "first shaft body 850a ") Stands from an outer surface 893 at the + Y axis direction side of the lever 80 in the + Y-axis direction. The other shaft body 850b the pair of shaft bodies 850 (as "second shaft body 850b ") Stands from an outer surface 891 at the -Y axis direction side of the lever 80 in the -Y axis direction. The outer surfaces 891 and 893 are also called side surfaces 891 and 893 designated. That on the lever 80 provided pair of shaft bodies 850 defines in a simple way the axis of rotation 800c by using a holder as will be described later.

According to this embodiment, each of the shaft bodies 850 an inner arcuate surface 852 , an outer arcuate surface 854 and radial side surfaces 856 and 858 on. The respective areas 852 . 854 . 856 and 858 form the peripheral surface of the shaft body 850 , The inner arcuate surface 852 and the outer arcuate surface 854 are each called the "first curved surface 852 "And" second curved surface 854 ' designated. The centers of the inner arcuate surface 852 and the outer arcuate surface 854 correspond to the axis of rotation 800c , The inner arcuate surface 852 is at the position closer to the second apparatus side sidewall member 604 as the outer arcuate surface 854 (that is, at the -X-axis direction side thereof). Like in the 20 is shown forms the inner arcuate surface 852 an arc with a radius R1a about the axis of rotation 800c at the cross section parallel to the X-axis and the Z-axis. The outer arcuate surface 854 forms an arc with a radius R2a around the axis of rotation 800c at the cross section parallel to the X-axis and the Z-axis. The radius R1a is smaller than the radius R2a. As described above, each shaft body has 850 the inner arcuate surface 852 and the outer arcuate surface 854 which are concentric as part of the peripheral surface, the former being at the position closer to the second apparatus side sidewall member 604 as the outer arcuate surface 854 is arranged. The rotation axis 800c can therefore be attached to the cartridge 20 closer position in the cartridge chamber 602 be arranged without the cartridge 20 to impair. This allows the engagement portion 212 of the first restriction section 210 the cartridge 20 through the engaging portion 810 is detected while a deviation from the first detection position 810L is reduced. When the rotation axis 800c at one of the cartridge 20 would be located distant position, a shift of the lever 80 from the mounting position, for the correct mounted condition of the cartridge 20 is provided, a significant displacement of the engaging portion 810 in the Z-axis direction. Arranging the axis of rotation 800c at the cartridge 20 closer position advantageously reduces the displacement of the engagement portion 810 in the Z-axis direction when the lever 80 in the state in which the cartridge 20 is suitably attached to the intended mounting position is moved from the standard position. Such an arrangement makes it possible for the cartridge 20 through the engaging portion 810 with less deviation from the first locking position 810L is detected. Adjusting the radius R2a of the outer arcuate surface 854 such that it is greater than the radius R1a of the inner arcuate surface 852 is advantageously prevents deterioration of the strength of the shaft body 850 , The "locked position" (first locked position) 810L "Indicates the position at which a first device-side detection surface 811 (first part of the engaging section 810 ) on the first cartridge-side detection surface 211 (First abutment of the first cartridge-side restriction section 210 ) abuts when the cartridge 20 attached to the attachment position set as the ideal intended position.

The engaging section 810 serves to the cartridge 20 in the attached state and determine the movement of the cartridge 20 to restrict. Like in the 21 is shown is the engaging portion 810 at the -Z axis direction end of the lever 80 intended. The engaging section 810 is in the state in which the cartridge 20 on the holder 60 is mounted on the -Z axis direction side of the rotation axis 800c intended.

Like in the 21 is shown, represents the engagement portion 810 the first cartridge-side restriction section 210 ( 5 ) by two parts. The engaging section 810 includes the first device-side detection surface 811 as the first part (the first device-side restricting element), a groove 815 and a second device-side detection surface 813 as the second part (the second device side restricting element). According to this embodiment, the two device side detection surfaces are 811 and 813 of the engaging portion 810 arranged so that they intersect each other.

The first device-side detection surface 811 is a curved surface with an arc shape around the axis of rotation 800c , The first device-side detection surface 811 has accordingly the arc shape around the axis of rotation 800c on the cross section parallel to the X axis and the Z axis (that is, the cross section parallel to the XZ plane, the cross section perpendicular to the Y axis). For attaching the cartridge 20 on the holder 60 This structure makes it possible to have the first device-side detection surface 811 easily to the locking position 810L is moved and the cartridge 20 finds. To remove the cartridge 20 from the holder 60 This structure makes it possible to have the first device-side detection surface 811 easily the cartridge 20 releases. This structure accordingly ensures trouble-free attachment of the cartridge 20 on the holder 60 and easy removal of the cartridge 20 of this.

At the locking position (first locking position) 810L lies the first device-side detection surface 811 in the X-axis direction close to the rotation axis 800c , In other words, according to this embodiment, at the lock position (first lock position) 810L the first device-side detection surface 811 almost below the axis of rotation 800c arranged. More specifically, at the lock position (first lock position) 810L the first device-side detection surface 811 slightly at the -X axis direction side of the rotation axis 800c arranged. Accordingly, the first device-side detection surface defines 811 at the locking position 810L a plane showing the + Z axis direction force, which is the cartridge 20 in the attached state from the device side terminals 700 and the elastic element 648 receives, approximately at a right angle intersects. According to this embodiment, the plane is in contact with the first device side detection surface 811 as the curved surface, a substantially horizontal plane at the locking position 810L , This reduces the likelihood of disengaging the engagement between the first cartridge-side detection surface 211 and the first device-side detection surface 811 while the cartridge 20 is inserted in the printer. The first locking position 810L Therefore, in the X-axis direction, the position is preferably close to the rotation axis 800c and at the -X-axis direction side of the rotation axis 800c , This makes the plane in contact with the first device-side detection surface 811 essentially horizontal, preventing the + X axis directing force from being exerted on the cartridge 20 in the attached state, to the first apparatus-side detection surface 811 , Arranging the first locking position 810L close to the axis of rotation 800c Advantageously, in the X-axis direction, deviation of the lock position in the Z-axis direction decreases even if the actual lock position of the first cartridge-side lock surface 211 and the first device side Parking surface 811 slightly from the first locking position 810L differs. In other words, this reduces the deviation of the cartridge 20 in the Z-axis direction relative to the holder 60 and ensures the good electrical connection of the cartridge side ports 400 with the device side connections 700 , For example, the first locking position should be 810L on the cross-section of the lever 80 be arranged at the plane parallel to the X-axis and the Z-axis so that an angle A between the straight line passing through the axis of rotation 800c runs and is parallel to the Z-axis direction, and the straight line, which is the axis of rotation 800c with the first locking position 810L preferably not greater than 15 degrees, more preferably not greater than 10 degrees, and even more preferably not greater than 5 degrees. The angle A is also preferably not less than 1 degree.

Like in the 19 is shown, is the guide element 820 between the actuator 830 and the engaging portion 810 is provided so as to extend from the + Z-axis direction end to the -Z-axis direction end. The guide element 820 serves to the first cartridge-side restriction section 210 (in 12 shown) to the engaging portion 810 to guide while the movement of the cartridge 20 in the Y-axis direction in the course of attaching the cartridge 20 on the holder 60 is limited. The bullet 20 Therefore, it can be suitably attached to the intended attachment position.

The guide element 820 is a lower guide wall provided along the Y-axis direction 821 and a pair of guide walls 860 coming from the lower guide wall 821 are angled vertically in the -X-axis direction, formed recess. The lower guide wall 821 and the pair of guide walls 860 form the recess in a simple manner, around the first cartridge-side restriction section constructed as the projection 210 take. The pair of guide walls 860 includes a first guide wall provided on the + Y-axis direction side 860a and a second guide wall provided on the -Y axis direction side 860b , The shaft body 850a is on the outer surface 893 the first guide wall 860a arranged while the shaft body 850b on the outer surface 891 the second guide wall 860b is arranged.

The space between the two guide walls 860a and 860b that is the distance between the inner surfaces of the two guide walls 860a and 860b , is smaller than the Y-axis direction length of the cartridge 20 but larger than the Y-axis direction length of the first cartridge-side restricting portion 210 (again 12 can be found). For attaching the cartridge 20 on the holder 60 becomes the first cartridge-side restriction section 210 through the guide element 820 taken and in a simple and secure manner to the engaging portion 810 guided while the pair of guide walls 860a and 860b the movement of the cartridge 20 limited in the Y-axis direction and the lower guide wall 821 the movement of the cartridge 20 limited in the Z-axis direction.

Part of the lower guide wall 821 at the side of the engaging portion 810 has a groove 870 which is set up for the second section 214 the first cartridge side restriction section 210 ( 12 ). The groove 870 is from the surface of the lower guide wall 821 reset in the + X axis direction. The groove 870 extends from the center in the + Z-axis direction of the lower guide wall 821 to its -Z axis direction end.

The to the holder 60 set levers 80 is set up by its own weight, the first device-side detection surface 811 to the first locking position 810L to move. The lever 80 is tilted to the first fixture-side detection surface 811 at the -X axis direction side of the rotation axis 800c ( 21 ) to arrange when the shaft body 850 through the holder 690 being held. According to one embodiment, the lever 80 by placing the center of gravity of the lever 80 on the -Z axis direction side and on the -X axis direction side of the rotation axis 800c be inclined. According to a further embodiment, the lever 80 by placing the center of gravity of the lever 80 on the + Z axis direction side and on the + X axis direction side of the rotation axis 800c be inclined.

22 is a perspective detail view of the holder 690 and a perspective view of the lever 80 , The lever 80 gets through the bracket 690 held so that it in a rotatable manner on the holder 60 is appropriate. The 22 shows a partial structure of the holder 690 for holding the lever 80 , The holder 690 is from a combination of a first support member 650 and a second support member 680 built up. The holder 690 is made of a synthetic resin, more specifically, according to this embodiment, of an ABS resin. The first support element 650 has a pair of standing sections 651 and a through hole 658 on. According to this embodiment, the first support member 650 also the lead 636 serving as the third apparatus-side restriction member.

The pair of standing sections 651 the first support member 650 is over a space for picking up the lever 80 arranged. Each of the standing sections 651 has a bearing element 654 for receiving the shaft body 850 of the lever 80 on. According to this embodiment, each of the standing sections 651 also an engagement opening 656 which serves to the second support member 680 to engage.

The second support element 680 has a pair of standing sections 681 and a through hole 688 on. According to this embodiment, the second support member 680 also an elastic element 682 on.

The pair of standing sections 681 of the second support member 680 is about the same space as the section standing between the couple 651 the first support member 650 arranged. Each of the standing sections 681 has a blocking surface 684 for blocking the bearing element 654 on, to prevent the shaft body 850 of the lever 80 unintentionally from the bearing element 654 is decoupled. According to this embodiment, each of the standing sections 681 also one in the engagement opening 656 the first support member 650 to be fitted engaging projection 686 on.

For attaching the lever 80 on the holder 60 becomes the lever 80 between the pair of standing sections 651 arranged by the respective shaft body 850 of the lever 80 in the corresponding bearing elements 654 of the pair of standing sections 651 the first support member 650 be set. Subsequently, the two support elements 650 and 680 assembled so that the bearing elements 654 with the shaft bodies fitted therein 850 of the lever 80 through the corresponding blocking surfaces 684 of the second support member 680 be blocked. The first and second support members 650 and 680 then be on the wall of the holder 60 For example, in the through holes 658 and 688 attached screws. This brings the lever 80 in a rotatable manner on the holder 60 at.

23 is a sectional view showing the structure of the circumference of the lever 80 in the state shows in which the cartridge 20 on the holder 60 is appropriate. The relationship between the shaft body 852 of the lever 80 and the bearing element 654 the first support member 650 is related to 23 described. The 23 shows the cross section of the lever 80 , the cartridge 20 determines, on the plane, the first device-side detection surface 811 runs parallel to the X-axis and the Z-axis. The dashed line in 23 shows the projected shape of the shaft body 850 of the lever 80 and the two-dot chain line shows the projected shape of the bearing element 654 and the blocking surface 684 ,

How clear from the 23 it can be seen that the axis of rotation is 800c of the lever 80 by the contact of the inner arcuate surface 852 and the outer arcuate surface 854 of the shaft body 850 with the bearing element 654 positioned. A turning of the lever 80 counterclockwise (viewed from the + Y axis direction) causes the radial side surface 856 of the shaft body 850 on the bearing element 654 is applied. This restricts further rotation of the lever 80 counterclockwise (viewed from the + Y axis direction). A turning of the lever 80 clockwise (viewed from the + Y axis direction) causes the radial side surface 858 of the shaft body 850 at the blocking surface 684 is applied. This restricts further rotation of the lever 80 clockwise (viewed from the + Y axis direction). This ensures stable rotation of the lever 80 and keeps the cartridge 20 at the intended mounting position in the stable state.

During the rotation of the lever 80 lies the elastic element 682 on a rear engagement surface 880 of the lever 80 at the -Z axis direction side of the rotation axis 800c is arranged. The elastic element 682 accordingly limits the rotatable area of the lever 80 during the installation of the cartridge 20 on the holder 60 and removing the cartridge 20 of this. When attaching the cartridge 20 on the holder 60 lies the elastic element 682 at the rear engaging surface 880 of the lever 80 on and is elastically deformed, making it the rear engagement surface 880 in the direction that includes the -X axis direction vector component. This ensures the movement of the engagement portion 810 of the lever 80 to the locking position (first locking position) 810L ,

A-5. Attaching the cartridge 20 on the holder 60 and removing the cartridge 20 of this:

24 to 27 show the procedure for attaching or inserting the cartridge 20 on the holder 60 (Mounting procedure). The 24 to 27 are the 5 and 17 corresponding sectional views and arranged in chronological order in this order.

For attaching the cartridge 20 on the holder 60 The procedure first performs the cartridge 20 through the upper surface of the holder 60 a, like in the 24 is shown. The procedure then moves the cartridge 20 in the -Z axis direction or attachment direction to cause the side of the cartridge 20 of the second cartridge side restricting portion 220 first in the holder 60 enters, and leads the second cartridge-side restriction section 220 in the second device-side restricting element 620 one. In the state of 24 is the first cartridge-side restriction section 210 the cartridge 20 at the + Z-axis direction side of the engaging portion 810 of the lever 80 in the holder 60 arranged.

The bullet 20 is clockwise (viewed from the + Y axis direction) about the second cartridge-side restricting portion 220 which enters the second device-side restriction element 620 is introduced as the fulcrum of the rotation of the state of 24 turned, leaving the side of the cartridge 20 the third area 203 towards the lower wall element 601 of the owner 60 is moved. Like in the 25 is shown, moves the first cartridge-side restriction section 210 then in the -Z axis direction, while the movement of the cartridge 20 in the Y-axis direction and in the X-axis direction by the guide member 820 of the lever 80 that is the pair of guide walls 860a and 860b , and through the lower guide wall 821 , in the 19 are shown is limited.

If the cartridge 20 from the state of 25 is further rotated to the side of the third surface 203 pushing in becomes the first cartridge-side restricting section 210 pressed further in the -Z axis direction. Like in the 26 shown is the lever 80 then through the first cartridge-side restriction section 210 in the -X axis direction, so that it rotates counterclockwise (viewed from the + Y axis direction). The lever 80 lies on the elastic element 682 and receives the pressing force from the elastic member 682 in the direction to push back the lever 80 clockwise (viewed from the + Y axis direction). This pressing force is an external force including an -X-axis direction vector component. The rotatable area of the lever 80 is accordingly by the elastic element 682 limited. This condition of 26 in which the lever 80 on the elastic element 682 is applied and by the elastic element 682 is pressed, is maintained until the cartridge 20 is further pressed in and the first cartridge-side restriction section 210 over the guide element 820 of the lever 80 to be led.

If the cartridge 20 from the state of 26 is further rotated to the side of the third surface 203 pushing in becomes the first cartridge-side restricting section 210 finally via the guide element 820 of the lever 80 guided. The lever 80 is then rotated to the first cartridge-side restriction section 210 in the -X-axis direction, as in the 27 is shown. The engaging section 810 moves accordingly to the first locking position 810L and represents the first cartridge-side restriction section 210 at the first locking position 810L firmly. More specifically, as shown by the bottom right-hand side view, the first device-side detection surface is located 811 (first part) of the engaging portion 810 on the first cartridge-side detection surface 211 (first abutment part) of the first cartridge-side restricting portion 210 so that the movement of the cartridge 20 is limited in the + Z-axis direction. The second device-side detection surface 813 (second part) of the engaging portion 810 also lies on the second cartridge-side detection surface 213 (Second abutment part) of the first cartridge-side restricting portion 210 so that the movement of the cartridge 20 is limited in the + X-axis direction. Although the first cartridge-side detection surface 211 and the second cartridge-side detection surface 213 in the close up of the 27 as two separate, substantially vertical surfaces are shown, such as 27A can be seen, the first section 212 of the first restriction section 210 be formed with a curved surface, so that the first cartridge-side detection surface 211 and the second cartridge-side detection surface 213 are constructed as separate sections of the same surface. Alternatively, like the 27B it can be seen, the first section 212 of the first restriction section 210 be formed with a flat, skewed surface or other shape, so that the first cartridge-side detection surface 211 and the second cartridge-side detection surface 213 are constructed as separate sections of the same surface. As part of the attachment, the ink supply structure becomes 280 the cartridge 20 then with the print material supply tube 640 while the second cartridge side restricting section 220 with the second device-side restriction element 620 engages and the first cartridge-side restriction section 210 with the engaging portion 810 engages. This includes attaching the cartridge 20 on the holder 60 from. The appropriate attachment of the cartridge 20 at the intended mounting position causes an electrical connection between the cartridge-side terminals 400 and the device-side terminals 700 , allowing signal transmission between the cartridge 20 and the printer 50 is possible.

According to this embodiment, as in FIGS 23 and 27 is shown, the elastic element 682 set up in the state in which the cartridge 20 on the holder 60 is attached, not on the lever 80 and thus no external force on the lever 80 exercise. This reduces the likelihood of plastic Deformation of the lever 80 by an external force and the likelihood of deviation of the engaging portion 810 from the first locking position 810L , This accordingly ensures a stable electrical connection between the cartridge side ports 400 and the device-side terminals 700 ,

According to a further embodiment, the elastic element 682 be designed so that it is in the state in which the cartridge 20 on the holder 60 is attached to the lever 80 abuts and thereby a force on the lever 80 in the direction including the -X axis direction vector component. In this application, the elastic element exercises 682 continuous force on the lever 80 in the direction including the -X axis direction vector component regardless of the position of the lever 80 , This moves the engagement portion 810 with sufficient force to the first locking position 810L for attaching the cartridge 20 on the holder 60 , This gives a hard cracking sound to the user about fixing the cartridge 20 through the engaging portion 810 to inform.

According to a further embodiment, the elastic element 682 be omitted. This application reduces the total number of parts.

The procedure of removing the cartridge 20 from the holder 60 is described. To remove the cartridge 20 from the holder 60 the user presses the actuator 830 in the -X axis direction. In other words, the user exerts the external force Pr ( 5 ) on the actuator 830 in the direction including the -X axis direction vector component. The lever 80 then moves the engagement portion 810 around the axis of rotation 800c in the direction including the + X-axis direction vector component. At the same time, the first cartridge-side detection surface rotates 211 and this moves in the direction of in 23 shown arrow Y22. This solves the first cartridge-side restriction section 210 from the engaging portion 810 and eliminates the restriction on the movement of the side of the cartridge 20 the third area 203 in the + Z-axis direction. Elimination of restriction of movement of the cartridge 20 in the + Z-axis direction causes the side of the cartridge 20 the third area 203 by the pressing force Pt from the contact mechanism 70 moved in the + Z-axis direction. This moves the cartridge 20 from the state of 27 to the state of 26 , The bullet 20 is further counterclockwise (viewed from the + Y-axis direction) about the second cartridge-side restriction portion 220 which enters the second device-side restriction element 620 is introduced as the fulcrum of rotation turned to the side of the cartridge 20 the third area 203 from the lower wall element 601 of the owner 60 to pull away. This moves the cartridge 20 from the state of 26 to the state of 25 and on to the state of 24 , The user can put a force on the projection 260 in the direction involving the -X axis direction vector component to the cartridge 20 to turn. This operation rotates the side of the cartridge 20 the third area 203 counterclockwise (viewed from the + Y axis direction) and moves the side of the cartridge 20 the third area 203 in the + Z-axis direction. The user holds the side of the cartridge 20 the third area 203 and pulls the second cartridge-side restricting portion 220 from the second device side restricting element 620 away, so the cartridge 20 from the holder 60 to decrease.

As in the close up of the 27 is shown, includes the actuating element 830 of the lever 80 the opposite surface 831 of the actuating element. To remove the cartridge 20 from the holder 60 in the attached state, when the user is the actuator 830 pushes, the opposite surface 831 the actuating element in contact with the projection 260 , The opposite surface 831 of the actuator is inclined in a direction including an -X axis direction vector component and a + Z axis direction vector component. A turning of the lever 80 around the axis of rotation 800c in the direction of the arrow Y27 causes the opposite surface 831 the actuating element with the projection 260 is in contact and the lead 260 in a direction Yh which includes the -X axis direction vector component and the + Z axis direction vector component. This allows for removal of the cartridge 20 from the holder 60 , Even if the cartridge 20 through a part of the holder 60 stuck and not in the + Z-axis direction by the movement of the first cartridge-side detection surface 211 from the first locking position 810L in the + X-axis direction, the side of the cartridge can 20 the third area 203 by using the opposite surface 831 the actuating element and the projection 260 be moved in the + Z-axis direction.

A-6. Attachment detection method using attachment detection terminals:

28 is a block diagram showing the electrical structure of the board 40 the cartridge 20 and the printer 50 illustrated according to the first embodiment. The printer 50 includes a display field 590 , a power circuit 580 , one Main control circuit 570 and a sub-control circuit 550 , The display field 590 serves as a display unit for communicating various information, for example, the operating state of the printer 50 and the mounting state of the cartridge 20 , to the user. The display field 590 can be attached to one of the outside of the printer 50 visible operating unit (not shown) may be provided. The power circuit 580 includes a first power supply unit 581 for generating a first power supply voltage VDD and a second power supply unit 582 for generating a second power supply voltage VHV. The first power supply voltage VDD is the usual power supply voltage used for logic circuits (for example, a rated voltage of 3.3V). The second power supply voltage VHV is the high voltage (for example, a rated voltage of 42 V) used to drive the head 540 ( 2 ) is used for ink ejection. These voltages VDD and VHV become the sub-control circuit 550 supplied as they are supplied to the other circuits as required basis. The main control circuit 570 includes a processor 571 and a memory 572 , The sub-control circuit 550 includes a memory control circuit 551 and a mounting detection circuit 552 , The circuit structure, which is the main control circuit 570 and the sub-control circuit 550 is referred to as "control circuit".

From the on the board 40 the cartridge 20 ( 10 ) provided nine terminals are the reset terminal 432 , the clock connection 433 , the power connection 436 , the earth connection 437 and the data port 438 electrically with the storage unit 420 connected. The storage unit 420 is a non-volatile memory without an address port. In the storage unit 420 becomes a memory cell to be accessed based on the pulse number of the clock terminal 433 input clock signal SCK and from the data terminal 438 entered command data. The storage unit 420 receives data from the data port 438 or sends data to the data port 438 synchronous with the clock signal SCK. The clock connection 433 is used to apply the clock signal SCK from the sub-control circuit 550 ( 28 ) of the storage unit 420 supply. The printer 50 sets the power supply voltage (for example, the rated voltage of 3.3 V) for driving the memory unit 420 and the ground voltage (0 V) to the power port, respectively 436 and the ground connection 437 at. The power supply voltage for driving the storage unit 420 can be directly through the printer 50 applied first power supply voltage VDD or may be generated from the first power supply voltage VDD to be lower than the first power supply voltage VDD. The data connection 438 is for the transmission of a data signal SDA between the sub-control circuit 550 and the storage unit 420 used. The reset port 432 is used for a reset signal RST from the sub-control circuit 550 the storage unit 420 supply. The four attachment detection connections 431 . 434 . 435 and 439 are through a wiring on the board 40 the cartridge 20 ( 3 ) and are all grounded. For example, the attachment detection terminals are 431 . 434 . 435 and 439 with the ground connection 437 connected to be grounded. According to another embodiment, the attachment detection terminals 431 . 434 . 435 and 439 through any connection path without the ground connection 437 be grounded. As is clear from this description, the attachment detection terminals 431 . 434 . 435 and 439 with a portion of the memory ports (or memory unit 420 ), but these are preferably not with memory ports other than the ground terminal 437 or the storage unit 420 connected. Not connecting the attachment detection terminals to the memory terminal or the memory unit causes no signal or voltage other than an attachment test signal to be applied to the attachment detection terminals, and therefore ensures the accurate attachment detection. The four attachment detection connections 431 . 434 . 435 and 439 In the illustrated example, FIGS 28 connected by a wiring, but a part of the connection path can be replaced by a resistor.

In the 28 For example, the path designations SCK, VDD, SDA, RST, OV1, OV2, DT1, and DT2 are assigned to the respective connection paths representing the device-side ports 731 to 739 with the cartridge-side connections 431 to 439 the board 40 connect. The signal designations become for the route designations with reference to the connection paths to the memory unit 420 used.

29 illustrates the connection between the board 40 and the attachment detection circuit 552 , The four attachment detection connections 431 . 434 . 435 and 439 the board 40 are through the corresponding device-side connections 731 . 734 . 735 and 739 with the attachment detection circuit 552 connected. The four attachment detection connections 431 . 434 . 435 and 439 the board 40 are grounded. The communication paths between the device-side ports 731 . 734 . 735 and 739 and the attachment detection circuit 552 are each connected to the power supply voltage VDD (rated voltage of 3.3V) in the sub-control circuit 550 connected by a pull-up resistor.

In the illustrated example of 29 have the three connections 431 . 434 and 435 of the four attachment detection terminals 431 . 434 . 435 and 439 on the board 40 a good connection with the corresponding device-side connections 731 . 734 and 735 on. The attachment detection terminal 439 however, has a bad connection with the corresponding device-side connector 739 on. The voltage level of the connection paths for the three device-side connections 731 . 734 and 735 in the good connection state, the L level (ground voltage level) is, while the voltage level of the connection path for the device side terminal 739 in the bad connection state, the H level (power supply voltage VDD level) is. The attachment detection circuit 552 can check the voltage levels of these connection paths so as to determine the good / bad connection state with respect to each of the four attachment detection terminals 731 . 734 . 735 and 739 to investigate.

The contact portions cp of the four attachment detection terminals 431 . 434 . 435 and 439 on the board 40 are outside a first range 400P arranged, the contact portions cp of the memory terminals 432 . 433 . 436 . 437 and 438 includes. The contact portions cp of the four attachment detection terminals 431 . 434 . 435 and 439 are at four corners of a quadrilateral second area 400T arranged the first area 400P includes. The first area 400P is preferably a smallest possible quadrilateral, the contact sections cp of the five memory terminals 432 . 433 . 436 . 437 and 438 includes. The second area 400T is preferably a smallest possible quadrilateral, all contact portions cp of the cartridge side ports 431 to 439 includes.

In the state of good contact for all four attachment detection connections 431 . 434 . 435 and 439 points the cartridge 20 no significant inclination and this ensures the good contact for the memory ports 432 . 433 . 436 . 437 and 438 , In the bad contact state for one or more of the four attachment detection terminals 431 . 434 . 435 and 439 on the other hand shows the cartridge 20 a significant slope and this may be the bad contact for one or more of the memory ports 432 . 433 . 436 . 437 and 438 cause. According to a preferred embodiment, in the bad contact state, one or more of the four attachment detection terminals is shown 431 . 434 . 435 and 439 the attachment detection circuit 552 an information (string or image) indicating the failed attachment to the display panel 590 to notify the user of the failed attachment.

The contact portions cp of the attachment detection terminals 431 . 434 . 435 and 439 are arranged at the four corners, which are the first area, for the following reason 400P containing the contact portions cp of the memory terminals 432 . 433 . 436 . 437 and 438 includes, surrounded. In the state in which the cartridge 20 on the holder 60 is appropriate, there is some room for tilting the cartridge 20 so the board 40 the cartridge 20 relative to the contact mechanism 70 of the owner 60 can be inclined. For example, a tilting of the cartridge 20 to the connections 431 to 434 (More specifically, their contact portions) in the upper row R2 ( 10A ) on the board 40 farther from the contact mechanism 70 to arrange as the connections 435 to 439 (More specifically, their contact portions) in the lower row R1 ( 10A ), to the bad contact for one of the connections 431 to 434 in the upper row R2 lead. A tilting of the cartridge 20 to the connections 435 to 439 (More specifically, their contact portions) in the lower row R1 on the board 40 farther from the contact mechanism 70 to arrange as the connections 431 to 434 (More specifically, their contact portions) in the upper row R2 may result in bad contact for one of the terminals 435 to 439 in the lower row R1 lead. A tilting of the cartridge 20 to the left edge of the board 40 ( 10A ) farther from the contact mechanism 70 To arrange as the right edge, can lead to the bad contact for one of the connections 431 . 432 . 435 . 436 and 437 on the left side of the board 40 to lead. A tilting of the cartridge 20 to the right edge of the board 40 farther from the contact mechanism 70 Arranging as the left edge may lead to the bad contact for one of the ports 433 . 434 . 437 . 438 and 439 on the right side of the board 40 to lead. The bad contact can make a mistake while reading data from the storage unit 420 or while writing data to the storage device 420 cause. Checking the contact portions cp of all four attachment detection terminals 431 434 . 435 and 439 at the four corners outside the first area 400P containing the contact portions cp of the memory terminals 432 . 433 . 436 . 437 and 438 Advantageously, the bad / bad contact advantageously prevents the bad contact and resulting access error in the memory unit 420 because of such a tendency of the cartridge 20 ,

A-7. Advantageous Effects of the Embodiment:

A-7-1. Certain of the beneficial effects of this embodiment compared to the structures disclosed in US Publication No. 2005/0151811 and US Patent No. 6,276,780, previously discussed.

In the printing material supply system 10 according to this embodiment, the lever 80 on the holder 60 provided and the first cartridge-side restriction section 210 at the cartridge 20 intended. The cartridge-side restriction section 210 is at the -Z axis direction side of the rotation axis 800c of the lever 80 arranged. The engagement member for engaging with the holder is different from the structures in FIG US Publication No. 2005/0151811 in which the lever is integral with the cartridge is not located at the position between the axis of rotation and the actuating element of the lever. Accordingly, there is no need to provide a relatively large distance between the lever and the cartridge side surface. The structure of the embodiment accordingly shortens the distance between the lever 80 and the third area 203 the cartridge 20 that is, the dimension in the X-axis direction while the length of the lever, that is, the dimension in the Z-axis direction, is shortened. This allows a considerable size reduction of the printer 50 and the entire printing material supply system 10 and a size reduction of the packaging for the transport and distribution of the cartridges 20 , which advantageously reduces the transport costs and the partial costs. This advantageous effect is not achieved in that, as in the U.S. Patent No. 6,276,780 is simply the lever on the printer holder instead of the cartridge is provided. This beneficial effect is achieved by the axis of rotation 800c of the lever 80 between the actuator 830 and the engaging portion 810 is provided and the cartridge-side restriction section 210 at the -Z axis direction side of the rotation axis 800c of the lever 80 is arranged.

The printing material feed system 10 according to the embodiment includes the relatively short lever 80 and the first cartridge-side restricting section 210 with the small size and the simple structure (for example, a projection). This increases the rigidity of the lever 80 and the first cartridge side restriction section 210 compared with those in the US Publication No. 2005/0151811 structures described and allows a material with relatively high stiffness for the lever 80 and the first cartridge-side restricting section 210 (the bullet 20 ) to choose. This leads to the likelihood of plastic deformation or creep deformation of the lever 80 and the first cartridge side restriction section 210 is significantly reduced. In the attached state, the cartridge can 20 at the appropriate position in the holder 60 be maintained, whereby the normal or good contact between the cartridge side ports 431 to 439 and the device-side terminals 731 to 739 is maintained and poor continuity is reduced. Since the first cartridge-side restriction section 210 This embodiment has the small size and the simple structure, unlike the cartridges of US Publication No. 2005/0151811, there is no particular care in packaging for the transportation and distribution of the cartridges 20 , especially in vacuum packaging, required to prevent plastic deformation of the lever. This improves the user-friendliness. The provision of the projection as the first cartridge-side restricting portion 210 As has been described in the embodiment, is particularly preferred for this advantageous effect.

In the printing material supply system 10 According to the embodiment, the cartridge-side restricting portion 210 at the -Z axis direction side of the rotation axis 800c of the lever 80 arranged. As previously described, the device-side ports create 731 to 739 the pressing force Pt in the direction of pushing back the board 40 (that is, in the direction including the + Z axis direction vector component and the -X axis direction vector component) in the attached state of the cartridge 20 , It can be assumed that this compressive force Pt the cartridge 20 moved in the attached state in the + Z-axis direction. In the printing material supply system 10 However, the embodiment is the axis of rotation 800c of the lever 80 at the -Z axis direction side of the first cartridge-side restricting portion 210 arranged so that the lever 80 the movement of the cartridge 20 from the + Z axis direction side to the -Z axis direction side.

According to this embodiment, the first cartridge-side restricting portion 210 on the -Z axis direction side and on the -X axis direction side of the rotation axis 800c of the lever 80 arranged. If the cartridge 20 moving in the + Z-axis direction, creates a torque on the lever 80 , like in the 5 shown by the arrow M. This moment acts to cause the first cartridge-side restriction section 210 through the engaging portion 810 firmly pressed in the -X axis direction. This moment also acts as the engaging section 810 of the lever 80 according to a movement of the cartridge 20 in the -X axis direction by the X-axis direction vector component of the pressing force Pt moves. The bullet 20 in the attached state accordingly receives the force, so that it against the device-side lower wall element 601 and the second apparatus side sidewall member 604 is pressed.

This structure of the embodiment prevents the cartridge 20 unintentionally from the holder 60 is decoupled, whereby the normal or good contact between the cartridge-side terminals 431 to 439 and the device-side terminals 731 to 739 is maintained and the likelihood of poor continuity is reduced.

Like in the 27 is shown, includes the first cartridge-side restriction section 210 the first cartridge-side detection surface 211 that at the first part 811 of the engaging portion 810 is attached to the movement of the cartridge 20 in the + Z axis direction, and the second cartridge-side detection surface 213 that at the second part 813 of the engaging portion 810 is attached to the movement of the cartridge 20 in the + X axis direction. This ensures the production of in the 5 torque shown by the arrow M and more effectively reduces the likelihood of poor continuity between the cartridge side ports 431 to 439 and the device-side terminals 731 to 739 ,

Like in the 12 is shown, according to this embodiment, the first cartridge-side restricting section 210 the second section 214 on. The first cartridge-side restriction section 210 reduces the probability that the first cartridge-side restriction section 210 when attaching the cartridge 20 on the holder 60 at the position on the -Z axis direction side of the engaging portion 810 is detected. In the course of attaching the cartridge 20 on the holder 60 the user can use the cartridge 20 in the -Z-axis deeper into the holder 60 as in the state of 27 to press. Even in this case lies the second section 214 the first cartridge side restriction section 210 at the second device-side detection surface 813 of the lever 80 on, so that prevents the first cartridge-side restriction section 210 at the -Z axis direction side of the engaging portion 810 is arranged. This reduces the likelihood that the first cartridge-side restricting section 210 through the engaging portion 810 is detected at the unintentional locking position.

A-7-2. Reduction of the effects of an external force in the attached state of the cartridge:

30 shows the mounted or inserted state on the cartridge 20 exerted external force. During a printing process of the printer 50 the holder is moving 60 and the cartridge 20 in the main scanning direction (y-axis direction or width direction of the cartridge 20 ) back and forth. The bullet 20 accordingly receives during acceleration and deceleration of the holder 60 in the width direction, an external force (inertial force). The external force receiving cartridge 20 may be about the ink delivery structure 280 ( 27 ) and the printing material supply tube 640 in the rotational direction including the width direction vector component (Y-axis direction vector component). More specifically, the side of the cartridge 20 the third area 203 turn in the direction of the arrow YR1 while the side of the cartridge 20 the fourth area 204 can rotate in the direction of the arrow YR2. The side of the cartridge 20 the second surface 202 can also turn in the direction of the arrow YR3. The direction of the arrow YR1 and the direction of the arrow YR2 are the rotational direction about the Z-axis including the Y-axis direction vector component (width direction vector component). The direction of the arrow YR3 is the rotational direction about the X-axis including the Y-axis direction vector component (width direction vector component).

Moving the cartridge 20 in the direction of the arrow YR3 causes either the fifth surface 205 or the sixth area 206 the cartridge 20 is pulled up in the + Z-axis direction. As previously described, such a movement of the cartridge 20 in the + Z-axis direction, however, by the lever 80 limited. According to this embodiment, the first cartridge-side restricting portion is located 210 close to the cut part 295 , like in the 13 is shown. In other words, the first cartridge-side restricting section is located 210 near the end of the board 405 the board 40 , The first cartridge-side restriction section 210 is as close as possible to the cartridge-side ports 400 arranged. Since the first cartridge-side restriction section 210 through the lever 80 is determined, the circumference of the first cartridge-side restriction section 210 essentially no positional shift due to the external force. The provision of the cartridge-side connections 400 at the location of the extremely small positional displacement effectively prevents the erroneous positional alignment of the respective terminals 431 to 439 the cartridge-side connections 400 relative to the holder 60 , whereby the stable electrical connection between the cartridge-side connections 400 and the device-side terminals 700 is maintained. In order to ensure this advantageous effect, it is preferable for at least a part of the first cartridge-side restricting section 210 (especially the first cartridge-side detection surface 211 ) between the first outer part 435P and the second outer part 439P ( 10A ) in the Y-axis direction (width direction) (when the cartridge 20 from the side of the third surface 203 in the -X axis direction). Like in the 7 is shown, according to this embodiment, the corner portion 265 the cartridge 20 the step (seventh surface) 207 up, extending from the first surface 201 extends in the + Z-axis direction. The seventh area 207 is at the -X axis direction side and at the -Z axis direction side of the tapered surface (eighth surface) 208 arranged. The seventh area 207 has the third cartridge-side restriction element 250 on. Like in the 2 and the 14 to 16 is shown, the holder points 60 the third device-side restricting element (the projection) 636 on. The third cartridge-side restriction element 250 stands with the lead 636 in contact. This further limits the movement of the side of the cartridge 20 the third area 203 in the width direction around the printing material supply tube 640 and the ink supply structure 280 , The third cartridge-side restriction element 250 is preferably constructed as the pair of protrusion elements extending from the seventh surface 207 protrude in the + X axis direction to the projection 636 sandwiching, as described in the embodiment. This simple structure effectively limits the movement of the side of the cartridge 20 the third area 203 in the width direction around the printing material supply tube 640 and the ink supply structure 280 ,

Like in the 13 is shown, according to this embodiment, the terminal support structure 408 the board 40 and the third cartridge-side restricting element 250 arranged so that they partially overlap each other in the X-axis direction (when the cartridge 20 from the side of the first surface 201 in the + Z-axis direction). This further effectively restricts the movement of the cartridge 20 in the direction of the arrow YR1, thereby preventing the movement (deviation) of the cartridge side ports 400 relative to the holder 60 ,

In the above description is the on the cartridge 20 applied external force in the width direction by the movement of the cartridge 20 inertial force generated in the main scanning direction. The on the cartridge 20 However, applied external force is not limited to such inertial force. For example, in the off-carriage printer, the printhead moves in the main scanning direction, but is the cartridge 20 attached to the stationary holder and therefore does not move in the main scanning direction. In the case of the off-carriage printer, the cartridge may 20 but receive an external force. More specifically, an external force (inertial force) on the cartridge 20 for example, due to vibration caused by the movement of the print head in the main scanning direction.

A-7-3. Reduction of the inclination of the cartridge 20 in the attached state:

Like in the 12 is shown, according to this embodiment, the first cartridge-side restriction portion 210 is provided so as to intersect the plane Yc passing through the center of the width (Y-axis direction length) of the cartridge 20 runs. Like in the 5 is shown receiving the cartridge 20 in the attached state, the pressing forces Ps and Pt from the holder 60 which include the + Z axis direction vector component. These pressing forces Ps and Pt press the first cartridge-side restricting portion 210 against the engaging portion 810 of the lever 80 , Even if the cartridge 20 In the attached state, when shaken by the external force about the X-axis or the Z-axis, the first cartridge-side restricting portion moves 210 hardly in the vicinity of the position which intersects the plane Yc.

The first cartridge-side restriction section 210 is close to the cut part 295 that is near the end of the board 405 arranged. The provision of the first cartridge-side restriction section 210 , which is at the position very close to the cartridge-side connections 400 very little movement, ensures a stable electrical connection between the cartridge-side connections 400 and the contact mechanism 70 ,

The effective part of the first cartridge side restriction section 210 , which specifically serves the position of the cartridge side ports 400 restrict is the first cartridge-side detection surface 211 , It is therefore preferable to have the first cartridge-side detection surface 211 as close as possible to the cartridge-side connections 400 to arrange. An omission of the third section 215 the first cartridge side restriction section 210 and arranging the first section 212 in contact with the first page 290 allow it to be the first cartridge-side detection surface 211 closer to the cut part 295 or the end of the board 405 lies. This further ensures the stable electrical connection between the cartridge side ports 400 and the contact mechanism 70 ,

According to this embodiment, as in the 10 is shown, of the contact portions cp of the respective cartridge side ports 400 the ground connection 437 is provided with the contact portion cp at the center in the Y-axis direction at the position intersecting the plane Yc. The contact sections cp of the other connections 431 to 436 . 438 and 439 are arranged so that they are with Reference to the line of the intersection of the plane Yc and the ground terminal 437 as the axis are symmetrical. The plane Yc has particularly little movement because the position of the first cartridge-side restricting portion 210 is fixed. The cartridge-side connections 400 are provided on the plane Yc which has little motion or in its vicinity. In addition to providing the first cartridge-side restricting portion 210 at the position very close to the cartridge-side connections 400 ensures the arrangement of the cartridge-side connections 400 at the level Yc or their surroundings continue the stable electrical connection between the cartridge-side terminals 400 and the contact mechanism 70 ,

A-7-4. Fine adjustment of the inclined cartridge 20 in the attached state:

According to this embodiment, the first cartridge-side restricting portion 210 (More specifically, the first cartridge-side detection surface 211 ) not outside but within the area 40Y in the Y-axis direction between the first outer part 435P at the outermost + Y axis direction side of the cartridge side ports 400 is arranged, and the second outer part 439P at the outermost -Y axis direction side of the cartridge side ports 400 is arranged. After the cartridge 20 on the holder 60 was mounted, receive the cartridge-side connections 400 the force with the + Z axis direction vector component from the device side terminals 700 , so the inclination of the cartridge 20 or more specifically, the direction of the tapered terminal support structure 408 at the the cartridge-side connections 400 are provided, fine tuned. The manufacturing error may be the positions of the respective device-side ports 731 to 739 from the device side beveled surface 708 or the horizontality of the first cartridge-side detection surface 211 the first cartridge-side restriction element 210 to change. Even in such cases, the fine adjustment ensures the direction of the tapered terminal support structure 408 the stable electrical connection between the cartridge-side connections 400 and the device-side terminals 700 ,

31 shows a fine adjustment of the direction of the tapered connection carrier structure 408 , The position of the cartridge 20 after fine adjustment of the position of the cartridge 20 is shown by the dashed line. In this example, the attachment detection terminal stands 731 the device side connections 700 in the + Z-axis direction by more than the intended amount from the device side beveled surface 708 ( 18 ). In this case, the tapered connection carrier structure receives 408 from the attachment detection terminal 731 a force Ph in a direction including the + Z-axis direction vector component. Arranging the first cartridge-side detection surface 211 within the range 40Y allows more rotation of the cartridge 20 around the X-axis. In other words, applying the force Ph to the tapered terminal support structure 408 a fine adjustment of the position of the cartridge 20 , In the illustrated example of 31 becomes the position of the cartridge 20 so finely adjusted that they are towards the side of the sixth surface 206 is inclined.

A-7-5. Advantageous effects of the second cartridge-side restriction section 220 :

The bullet 20 has the second cartridge side restriction section 220 on the fourth surface 204 ( 27 ), which serves to control the movement of the cartridge 20 from their + X axis direction sides in the + Z axis direction. This further ensures the stable electrical connection between the cartridge side ports 400 and the device-side terminals 700 ,

According to this embodiment, the second cartridge-side restricting portion 220 that of the fourth surface 204 protrusion protruding in the -X axis direction. The second cartridge-side restriction section 220 becomes the second device side restricting element 620 ( 3 ) in the shape of the through hole of the holder 60 introduced. The user turns the cartridge 20 around the surroundings of the restriction device which is in the second device-side 620 ( 3 ) introduced second cartridge side restriction section 220 for attaching the cartridge 20 on the holder 60 and removing the cartridge 20 of this. The second device-side restricting element 620 Accordingly, it serves as the guide for attaching the cartridge 20 on the holder 60 and removing the cartridge 20 of this. This structure allows the attachment of the cartridge 20 on the holder 60 and removing the cartridge 20 of this. The second cartridge-side restriction section 220 in the form of the projection can easily on the fourth surface 204 the cartridge 20 be provided.

A-7-6. Advantageous effects of the projection 260 :

Like in the 27 is shown, according to this embodiment, the cartridge 20 the lead 260 on the + Z-axis direction side of the first cartridge-side restricting portion 210 at the third area 203 on. To remove the cartridge 20 from the holder 60 causes exertion of force on the actuator 830 of the lever 80 from the + X-axis direction side to the -X- Axis direction side that the actuator 830 with the lead 260 is in contact and the lead 260 in the direction Yh which includes the + Z axis direction vector component. The lead 260 accordingly receives the force with the + Z axis direction vector component. This allows the removal of the cartridge 20 from the holder 60 by using the actuator 830 , Even if the cartridge 20 through a part of the holder 60 stuck and not by the movement of the first cartridge-side detection surface 211 from the first locking position 810L in the + X-axis direction in the + Z-axis direction, the side of the cartridge can 20 the third area 203 by using the projection 260 be moved in the + Z-axis direction.

Although the external force according to the embodiment directly from the actuator 830 on the lead 260 is exercised, the external force can not from the actuator 830 on the lead 260 be exercised. Turning the actuator 830 releases the engaging section 810 from the first cartridge-side restricting portion 210 and eliminates the restriction on the movement of the side of the cartridge of the third surface 203 in the + Z-axis direction. Eliminating the restriction on the movement of the cartridge 20 in the + Z-axis direction causes the side of the cartridge 20 the third area 203 by the pressing force Pt from the contact mechanism 70 moved in the + Z-axis direction. The lead 260 the cartridge 20 moves simultaneously in the direction Yh. The user holds the circumference of the projection moving in the direction Yh 260 and easily takes the cartridge 20 from the holder 60 from. The provision of the projection 260 improves operability to remove the cartridge 20 from the holder 60 even without direct exertion of external force from the actuator 830 on the lead 260 ,

A-7-7. Advantageous effects of the position of the ink supply structure 280 :

Like in the 27 is shown, according to this embodiment, the Tintenzuführstruktur 280 at the position closer to the fourth surface 204 as to the third surface 203 on the first surface 201 intended. The distance between the outer surface of the ink supply structure 280 and the third area 203 in the X-axis direction is accordingly larger than the distance between the outer surface of the Tintenzuführstruktur 280 and the fourth surface 204 , The cartridge-side connections 400 are on the beveled Anschlussträgerstruktur 208 next to the third area 203 intended. In other words, the ink supply structure is 280 at the of the cartridge-side connections 400 provided remote position. This reduces the likelihood of ink on the cartridge-side ports 400 adheres, and prevents the bad contact between the cartridge-side terminals 400 and the device-side terminals 700 ,

A-7-8. Advantageous effects of the ground connection 437 :

According to this embodiment, as in the 10A is shown, of the contact portions cp of the cartridge-side terminals 400 the ground connection 437 having the contact portion cp at the center in the Y-axis direction, provided at the position which is the center of the width (Y-axis direction length) of the cartridge 20 extending plane Yc intersects. The ground connection 437 is set up in the course of attaching the cartridge 20 on the holder 60 in front of the other cartridge-side connections 431 to 436 . 438 and 439 with the contact mechanism 70 to be in contact. The first of the holder 60 on the board 40 Therefore, the applied pressing force becomes substantially at the center of the width or the Y-axis direction length of the cartridge 20 generated. This prevents the on the board 40 exerted compressive force acts so that it is the cartridge 20 in the Y-axis direction, thereby enabling the attachment of the cartridge 20 at the intended attachment position. Such a contact of the ground connection 437 with the contact mechanism 70 of the owner 60 in front of the other cartridge-side connections 431 to 436 . 438 and 439 prevented or reduced by the earthing function of the ground connection 437 Advantageously, the problems caused by high voltage and interference, even if an unexpected high voltage to the cartridge 20 is created.

A-7-9. Advantageous effects of the shape of the first device-side detection surface 811 :

Like in the 21 is the first device-side detection surface 811 the curved surface with the arc shape around the rotation axis 800c on the cross-section parallel to the X-axis and the Z-axis. This ensures easy operation for attaching the cartridge 20 on the holder 60 and removing the cartridge 20 of this. Forming the first device-side detection surface 811 as the curved surface reduces the amount of back-pressing in the + Z-axis direction by the elastic member 648 ( 27 ) in the course of attaching the cartridge 20 on the holder 60 , This ensures the good electrical contact between the cartridge-side connections 400 and the device-side terminals 700 ,

An example of such an advantageous effect will be described with reference to FIGS 32A to 32F described. The vertical direction of the 32A to 32F corresponds to the Z-axis direction; the upward direction of the drawings corresponds to the + Z axis direction and the downward direction corresponds to the -Z axis direction, these directions being opposite to each other. The 32A to 32C show the attachment of a cartridge using the first device-side detection surface formed as the curved surface 811 and are arranged in chronological order in this order. The 32D to 32F show attaching a cartridge using a first device-side detection surface formed as a plane 811T and are arranged in chronological order in this order.

Like in the 32A is shown, moves to attach the cartridge 20 on the holder 60 the first cartridge-side restriction section 210 in the -Z axis direction, while at the lower guide wall 821 is applied. Like in the 32B is shown moves when the first cartridge-side restriction section 210 through the lower guide wall 821 moving further in the -Z axis direction, the first device-side detection surface 811 in the direction of the arrow Y32. If the user is the cartridge 20 firmly presses in the -Z axis direction becomes the first cartridge-side restricting portion 210 at the -Z axis direction side of the first device side detection surface 811 arranged. If the user is the cartridge 20 lets go, the cartridge becomes 20 by the compressive forces PS and Pt of the elastic element 648 and the device-side connections 700 in the + Z-axis direction pushed up. Like in the 32C is the push-up amount of the first cartridge-side restricting portion 210 the cartridge 20 D1, when the first device-side detection surface 811 as the curved surface is formed.

As in the 32D to 32F is shown, when the first device-side detection surface 811T is formed as the plane, the push-up amount of the first cartridge-side restriction portion 210 D2, which is larger than D1.

In the attached state of the cartridge 20 For example, the first device-side detection surface formed as the curved surface 811 may be disposed on the -Z axis direction side than the first device side detection surface formed as the plane 811T , This reduces the push-up amount of the first cartridge-side restricting portion 210 ,

According to this embodiment, the is at the predetermined or first locking position 810L arranged first device-side detection surface 811 close to the axis of rotation 800c in the X-axis direction ( 21 ). This reduces the moving distance of the first apparatus side detection surface 811 in the Z-axis direction, even if the actual lock position in the X-axis direction from the first lock position 810L differs. This accordingly prevents a deviation of the cartridge 20 in the Z-axis direction relative to the holder 60 ,

B. Additional Embodiment:

33 illustrates a printer 50a according to a second embodiment. The 33 shows the cross section of the cross section of the 17 according to the first embodiment. The difference to the printer 50 The first embodiment is that a holder 690a not the elastic element 682 having. Otherwise, the printer rejects 50a The second embodiment has the same structure as the printer 50 of the first embodiment. The same elements are labeled with the same characters and will not be explained separately here. The on the printer 50a attached cartridge 20 has the same structure as the one on the printer 50 the first embodiment mounted cartridge 20 on.

Like in the 33 is shown, the holder has 690a no elastic element for pressing the lever 80 in the direction including the -X axis direction vector component. The lever 80 However, it is designed so that its first device-side detection surface 811 by its own weight at the first locking position 810L is arranged so that the first cartridge-side detection surface 211 the cartridge 20 through the first device-side detection surface 811 of the lever 80 is detected.

The printer 50a The second embodiment has the similar advantageous effects as the printer 60 of the first embodiment. In addition, the structure of the bracket decreases 690 without an elastic element the possible damage or possible breakage of the holder 690 and this lowers the total number of parts to the manufacturing cost of the printer 50a to reduce.

C. Third embodiment:

34 is a perspective view showing the appearance of a cartridge 20b illustrated according to a third embodiment. The difference to the cartridge 20 the first embodiment ( 7 ) is the size of the cartridge 20b , Otherwise, the cartridge points 20b the third Embodiment the same structure as the cartridge 20 of the first embodiment. The same elements are labeled with the same characters and will not be explained separately here. A printer of the third embodiment is used for the cartridge 20b used, but has the same structure as that of the holder 60 and the respective one on the holder 60 provided elements (for example, the lever 80 ) of the first embodiment.

The bullet 20b has larger dimensions than the cartridge 20 of the first embodiment and is capable of containing a larger amount of ink. The bullet 20b is attachable to a cartridge mounting structure of a large ink jet printer capable of printing on large paper (for example, sizes A2 to A0). The bullet 20b is attached to the cartridge attachment structure of the large ink jet printer in the -Z axis direction as the attachment direction SD. According to this embodiment, the -Z axis direction is the horizontal direction. In the state in which the cartridge 20b is attached to the cartridge mounting structure, the X-axis direction is the vertical direction. More specifically, the + X axis direction is the vertically upward direction and the -X axis direction is the vertically downward direction.

D. Modifications of the Cartridge Structure:

35 to 37 show variations of the cartridge structure. These cartridges are designed for the printer, which has the same structure as the printer 50 according to the first embodiment. The elements of these cartridges, which are equal to those of the cartridge 20 of the first embodiment are designated by the same characters.

D-1. Modifications of the outer cartridge form:

35A to 35H FIG. 12 are conceptual diagrams showing outer cartridge shapes according to other embodiments. FIG. One in the 35A shown cartridge 20c has a housing with an elliptical or oval side surface. The bullet 20c has the first cartridge-side restriction section 210 and the board 40 on, which are provided on the front surface. The ink delivery structure 280 is on the bottom surface of the cartridge 20c formed and the second cartridge-side restriction section 220 is on the back surface of the cartridge 20c intended. This cartridge 20c has a fixed width when the cartridge 20c is viewed from the front surface side. This cartridge 20c is with the in the 7 shown cartridge 20 compatible, as long as the first and the second cartridge-side restriction section 210 and 220 , the circuit board 40 and the ink supply structure 280 are constructed to match the corresponding parts in the printer 50 can be connected.

One in the 35B shown cartridge 20d like the one in the 7 shown cartridge 20 an approximately rectangular parallelepiped shape. The big difference to the cartridge 20 of the 7 is that the eighth surface 208 not continuously from the lower end of the third surface 203 runs. The in the 35G shown cartridge 20l is in shape and design of the cartridge 20d Similarly, the arrangement of the first cartridge-side restriction section 210 closer to the connection carrier structure 408 is provided. The in the 35C and 35D shown cartridges 20e and 20f do not have a seventh area in the cartridge 20 of the 7 is included. One in the 35E shown cartridge 20g shows the board 40 on that at the eighth surface 208 is attached by a spring. One in the 35F shown cartridge 20h has an articulated or otherwise movable surface 208h instead of the eighth surface 208 on and the board 40 is on the movable surface 208h appropriate. While the cartridge 20h is inserted into the printer, the movable surface moves 208h from the position indicated by the broken line to the position indicated by the solid line. Once the cartridge 20h suitable inserted in the printer and the movable surface 208h in the position indicated by the solid line, the contact portions of the terminals are on the board 40 aligned at the contact portion level TP. These cartridges 20c to 20g are also in the 7 shown cartridge 20 compatible, as long as the first and the second cartridge-side restriction section 210 and 220 , the circuit board 40 and the ink supply structure 280 are constructed to match the corresponding parts in the printer 50 can be connected. One in the 35H shown cartridge 20m has an elongated element 211 on, at one end with the first cartridge-side restriction section 210 is connected and at the other end by a hinge or other rotatable mechanism with the upper end 202 the cartridge 20m connected is. Although the terminals were planar in the above embodiments, the terminals could be elongated or wireformed or have other shapes. For example, the shows 35I an embodiment with elongated connections 400n wherein the contact portions cp are aligned at the terminal level TP when the cartridge 20j inserted into the printer. When in the 35J embodiment shown includes a cartridge 20j a contact mechanism 70j which essentially has the same construction (including the construction of the connections) as the one in the 18 shown device-side contact mechanism 70 having. The contact mechanism 70j has springy connections Contact sections on when the cartridge 20j inserted into the printer, with the connectors 700 the contact mechanism 70 are in contact and are aligned substantially at the terminal level TP. In embodiments such as those of 35I and 35J in which the terminals are not planarized, the "terminal support structure" and the "bevelled surface" may be considered as the portion of the cartridge terminals carrying the contact portions, and are therefore substantially the same as the portions of the terminals formed by the contact section plane TP are displayed. In addition, the section of the restriction section 210 which engages with the device side lever, at a position closer to the position where the contact portion plane TP the front surface 203 cuts, and arranged to the contact portions cp itself as to the cutting area 1) of the upper surface 202 and the front surface 203 , 2) one of the upper surface 202 and the front surface 203 and an extension of the other of the upper surface 202 and the front surface 203 or 3) extensions of both the upper surface 202 as well as the front surface 203 (For example, when the cartridge body has an upper and a front surface which, as in the embodiments of the 35A and 35D are formed). In the embodiment of the 35J is the board 40j the cartridge 20j inside of the contact mechanism 70j arranged and contacts these the device-side contact mechanism 70 via indirect contact through the contact mechanism 70j ,

How clear from the in the 35A to 35H As shown in the examples shown, there are various other modifications of the outer cartridge mold. If the cartridge has a different outer shape than the approximately rectangular Parallelepipedform, as indicated by the dashed lines in the 35A and 35D can be shown, the six faces of the rectangular parallelepiped, that is, the lower surface 201 (first surface), the upper surface 202 (second surface), the front surface 203 (third surface), the back surface 204 (fourth surface), the left side surface 205 (fifth surface) and the right side surface 206 (sixth area) are virtually accepted. In the description hereof, the terms "area" and "level" refer to a virtual plane or the non-existent (imaginary) plane, as in FIGS 35A or 35D is shown, and the actual level, as in the 7 and 8th is shown. The terms "surface" and "plane" include both planar surfaces and curved surfaces.

G. 7 Seventh modification:

The invention may be practiced by the following descriptions and changes. The characters in parentheses after the elements in each of the descriptions correspond to the characters of the respective elements described in the first embodiment.

G-7-1. First change

An ink cartridge ( 20 ) designed to be detachable on an inkjet printing device ( 50 ), the inkjet printing device ( 50 ) a plurality of device-side contact-forming elements ( 731 - 739 ) designed and arranged to apply an elastic force (Pt) to the ink cartridge ( 20 ) when the ink cartridge ( 20 ) against the device-side contact-forming elements ( 731 - 739 ), and the inkjet printing device ( 50 ) also a lever ( 80 ) with an engaging portion ( 810 ), and the ink cartridge ( 20 ) comprises: a cartridge body ( 22 ), which has a front side ( 203 ), a back ( 204 ), an upper end ( 202 ) and a lower end ( 201 ), the front side ( 203 ) and the back ( 204 ) are opposite each other and the upper end ( 202 ) and the lower end ( 201 ) face each other; an electrical device, an ink chamber ( 200 ) for storing ink; one at the lower end ( 201 ) of the cartridge body ( 22 ) arranged ink supply structure ( 280 ) designed and arranged to remove ink from the ink chamber ( 200 ) to the inkjet printing device ( 50 ), the ink feed structure ( 280 ) an attachment direction (SD) leading edge ( 288 ) having a plane (BP) of the ink cartridge ( 20 ) Are defined; a connection carrier structure ( 408 ), which are close to the front ( 203 ) of the cartridge body ( 22 ), wherein the connection carrier structure ( 408 ) a plurality of electrically conductive connections coupled to the electrical device ( 400 ) and the connections ( 400 ) and at the connection carrier structure ( 408 ) are arranged to be connected to contact sections (cp) of the connections (cp) 400 ) with the contact-forming elements ( 731 - 739 ) and receive the elastic force (Pt) from them when the ink cartridge ( 20 ) on the printing device ( 50 ), wherein the contact sections (cp) are arranged essentially in a contact section plane (TP) which is neither parallel nor perpendicular to that through the front edge (TP). 288 ) defined level (BP); and a first restriction section ( 210 ), which is designed with the engagement section ( 810 ) of the lever ( 80 ) to engage a movement of the ink cartridge ( 20 ) in a direction opposite to the attachment direction (SD) direction (RD), wherein the engaging portion (R) ( 212 ) of the first restriction section ( 210 ) next to the connection carrier structure ( 408 ) is arranged.

Some of the advantages of the above modification of the seventh modification will now be described. The Ports must be accurately located and stably fixed while the ink cartridge is inserted into the printer to ensure a reliable electrical connection between the cartridge and the printer. Since the engaging portion of the first restricting portion is located adjacent to the terminal support structure, a positioning action of the first restricting portion comes close to the position where positioning is most needed (that is, at the terminals of the terminal support structure). The elastic force from the device side terminals can be appropriately counteracted. In addition, a positional shift of the terminals, which may occur due to vibration during printing operations, can be suppressed. Therefore, the positioning of the terminals is more stable, whereby the stable electrical connection between the cartridge-side terminals and the device-side terminals is maintained.

In addition, since the lever is not integrally formed with the cartridge, the material for producing the cartridge may be different from the material used to manufacture the lever. In addition, the material of the cartridge may be selected with less regard to flexibility and durability requirements and with a greater attention to other properties, such as resistance to ink.

In addition, since the lever is not disposed on the cartridge, no special care is required to prevent creep of the lever during packing of the cartridge for transportation and distribution. This simplifies the packaging requirements and improves the user-friendliness. Since the lever is not an integral part of the cartridge, the cartridge can be made smaller. This further enables size reduction of the packaging material, such as a paper or box, used to package the cartridge for transport or distribution of the cartridge, thereby advantageously reducing transport and component costs. In addition, since the lever is not formed integrally with the cartridge, the first cartridge-side restricting portion with a small size and simple structure and, for example, compared with those in US Publication No. 2005/0151811 described structures, higher rigidity are formed. As a result, the likelihood of plastic deformation of the first cartridge-side restricting portion is significantly reduced. In the attached or inserted state, the cartridge can be held in the proper position in the cartridge attachment structure, thereby maintaining normal or good contact between the cartridge side ports and the device side ports and reducing the likelihood of poor electrical communication. Since the first cartridge-side restricting portion may have a small size and a simple structure, unlike the cartridges of US Publication No. 2005/0151811, no special care is required in the package for transporting and distributing the cartridge to creep deformation of the lever to prevent. This reduces the packaging requirements and also improves the user-friendliness.

It is possible that the structure connecting the cartridge terminals and the engaging portion of the cartridge is only a rigid structure (which is for the flexible levers of the US Publication No. 2005/0151811 not the case). In this case, less vibration is transmitted from the engaging portion to the cartridge terminals, so that the electrical communication is more stable.

Since the contact section plane (TP) of the terminals is neither parallel nor perpendicular to that through the leading edge (FIG. 288 ) defined plane (BP), the surface of the cartridge ports can be wiped properly during insertion of the cartridge into the printer. In addition, this design reduces or eliminates insulation debris (dust) that can be generated when the printer ports rub against the board for long periods of time during the mounting of the cartridge.

Since the printer terminals exert an elastic force on the cartridge terminals, which includes a vector component in the direction in which the cartridge is detached from the printer, there is no need to use a spring like the one in FIG U.S. Patent 6,955,422 described spring 103 provided. In other words, the elastic force from the printer-side terminals serves to press both the printer-side and cartridge-side terminals against each other and to move the cartridge in the direction for detaching from the printer when the engagement between the first restricting portion and the printer lever is released. Therefore, there is no need to provide an additional spring as in the case of US Pat. No. 6,955,422, thereby allowing a simpler structure and reduced costs. As a result, since the first restricting portion is adapted to engage with the engaging portion of the lever so as to restrict the movement of the cartridge in the direction opposite to the mounting direction, the position of the cartridge terminals with respect to the mounting direction by the elastic Force of the device-side contact-forming elements and with respect to the direction opposite to the mounting direction by the first restriction portion maintained when the cartridge in the Printer is used. Since the cartridge terminals are "embedded" in this manner, they are firmly fixed against movement both in the mounting direction and in the direction opposite to the mounting direction. Therefore, there is less likelihood of misalignment or separation between the cartridge terminals and the device side contact-forming members as compared with the one-sided restriction by the elastic member 40 and the associated structure of the U.S. Patent No. 7,008,053 ,

Application 1

The ink cartridge as described above, wherein the contact portion plane (TP) is at an angle of between approximately 25 and 40 degrees to that through the leading edge (FIG. 288 ) defined level (BP).

How about the 42A - 45 is discussed, if the contact portion plane is at an angle between approximately 25 and 40 degrees relative to the plane defined by the leading edge, excessive wiping is prevented and sufficient force for preventing half insertion can be exerted.

Application 2

The ink cartridge as described above, when the front side ( 203 ) of the cartridge body ( 20 ) is considered to be such that the ink feed structure ( 280 ) downwards, the engaging portion ( 212 ) of the first restriction section ( 210 ) to the left of the rightmost contact portion of the plurality of terminals ( 400 ) and to the right of the leftmost contact portion of the plurality of terminals ( 400 ) is arranged.

If the ink cartridge is attached to the printing device, if the cartridge is held too tight, contact with some of the device-side contact forming elements (for example, port 734 in the 31 ) not sure. By disposing the engagement portion of the first restricting portion to the left of the rightmost contact portion of the plurality of terminals and to the right of the leftmost contact portion of the plurality of terminals, the ink cartridge may incline sufficiently so that the electrical connection between the plurality of terminals and the device side contact forming elements becomes even more stable can be.

Application 3

The ink cartridge as described above ( 20 ), which further comprises a second restriction section ( 220 ) on the back ( 204 ) of the ink cartridge ( 20 ), the second restriction section ( 220 ) is designed and set up with an appropriate section ( 620 ) of the inkjet printing device ( 50 ), and the distance (B) between the engaging portion of the second restricting portion (FIG. 220 ) and the front edge ( 288 ) defined plane (BP) is greater than the distance (A) between the engaging portion ( 212 ) of the first restriction section ( 210 ) and the front edge ( 288 ) defined plane (BP), when the distances in one to the through the leading edge ( 288 ) defined plane (BP) vertical direction.

When the engaging portion of the second restricting portion is located farther from the plane defined by the leading edge than the engaging portion of the first restricting portion, the likelihood that the first restricting portion is disengaged from the printer engaging portion can be further increased as compared with the case where the engaging portion of the first restricting portion is disposed away from the plane defined by the leading edge than the engaging portion of the second restricting portion, can be reduced more effectively.

Application 4

The ink cartridge as described above ( 20 ), when, when the ink cartridge ( 20 ) so from the side ( 203 ) is considered that the engaging portion ( 212 ) of the first restriction section ( 210 ) lies to the right and the ink feed structure ( 280 ) downwards, the distance (A) between the engagement portion ( 212 ) of the first restriction section ( 210 ) and the front edge ( 288 ) defined plane (BP) is smaller than the distance (C) between a pivot ( 800c ) of the lever ( 80 ) and the front edge ( 288 ) defined level (BP) when the cartridge ( 20 ) is mounted when the distances in one to the through the leading edge ( 288 ) defined plane (BP) vertical direction.

When the distance between the engaging portion of the first restricting portion and the plane defined by the leading edge is smaller than the distance between a pivot point of the lever and the plane defined by the leading edge when the cartridge is mounted, the lever serves to move the cartridge restrict. This reduces the likelihood that the first restricting portion will be released or disengaged from the engaging portion of the lever, thereby creating a stable electrical connection between the plurality of terminals and the contact forming elements and reducing the likelihood of poor continuity. The first Restrictive portion may move about the axis of rotation of the lever when a force is exerted by the contact-forming elements on the attached cartridge. This reduces the likelihood that the engaging portion of the first restricting portion is decoupled from the engaging portion of the lever.

Application 5

The ink cartridge as described above, when the ink cartridge ( 20 ) so from the side ( 203 ) is considered that the engaging portion ( 212 ) of the first restriction section ( 210 ) lies to the right and the ink feed structure ( 280 ) downwards, the engaging portion ( 212 ) of the first restriction section ( 210 ) to the left of a pivot ( 800c ) of the lever is arranged when the cartridge is mounted.

When the cartridge is mounted such that the engaging portion of the first restricting portion is to the left of a pivot point of the lever, when the cartridge is viewed from the side so that the engaging portion of the first restricting portion is right and the ink supply structure is facing down, the first restricting portion generates a torque on the lever to rotate the lever about the axis of rotation of the lever in the direction opposite to the release direction. This reduces the likelihood that the engaging portion of the first restricting portion will be released from the engaging portion of the lever, and further ensures the stable electrical connection between the plural terminals and the apparatus-side contact forming members. Even if the cartridge receives a force, the first restriction portion would move with the cartridge. Such movement reduces the likelihood that the engaging portion of the first restricting portion will be released from the engaging portion of the lever.

Application 6

The ink cartridge as described above, when the front side ( 203 ) of the cartridge body ( 22 ) is considered to be such that the ink feed structure ( 280 ), at least a portion of the engaging portion (FIG. 212 ) of the first restriction section ( 210 ) substantially at the center of the ink cartridge ( 20 ) is arranged in the width direction.

By providing the first restricting portion in such a position that at least a portion of the engaging portion of the first restricting portion is located substantially at the center of the ink cartridge in the width direction, the first restricting portion is disposed extremely close to the plurality of terminals so that the electrical connection between the plurality of terminals and the device-side contact forming elements can be stable.

Application 7

The ink cartridge as described above, in which the ink through the leading edge ( 288 ) defined plane (BP) substantially at the lower end ( 201 ) is flush.

G-7-2. Second change

An ink cartridge ( 20 ) designed to be detachable on an inkjet printing device ( 50 ), the inkjet printing device ( 50 ) a plurality of device-side contact-forming elements ( 731 - 739 ) designed and arranged to apply an elastic force (Pt) to the ink cartridge ( 20 ) when the ink cartridge ( 20 ) against the device-side contact-forming elements ( 731 - 739 ), and the inkjet printing device ( 50 ) also a lever ( 80 ) with an engaging portion ( 810 ), and the ink cartridge ( 20 ) comprises: a cartridge body ( 22 ), which has a front side ( 203 ), a back ( 204 ), an upper end ( 202 ) and a lower end ( 201 ), the front side ( 203 ) and the back ( 204 ) are opposite each other and the upper end ( 202 ) and the lower end ( 201 ) face each other; an electrical device, an ink chamber ( 200 ) for storing ink; one at the lower end ( 201 ) of the cartridge body ( 22 ) arranged ink supply structure ( 280 ) designed and arranged to remove ink from the ink chamber ( 200 ) to the inkjet printing device ( 50 ), the ink feed structure ( 280 ) an attachment direction (SD) leading edge ( 288 ) having a plane (BP) of the ink cartridge ( 20 ) Are defined; a connection carrier structure ( 408 ), which are close to the front ( 203 ) of the cartridge body ( 203 ), wherein the connection carrier structure ( 408 ) a plurality of electrically conductive connections coupled to the electrical device ( 400 ) and the connections ( 400 ) and at the connection carrier structure ( 408 ) are arranged to communicate with the contact forming elements ( 731 - 739 ) of the inkjet printing device ( 50 ) and receive the elastic force (Pt) from them when the ink cartridge ( 20 ) on the printing device ( 50 ), the connections ( 400 ) are arranged substantially in a connection plane (TP) which is neither parallel nor perpendicular to the plane of the front edge (TP). 288 ) lies; and a first restriction section ( 210 ), which is designed with the engagement section ( 810 ) of the lever ( 80 ) to engage in such a movement the ink cartridge ( 20 ) in a direction opposite to the attachment direction (SD) direction (RD), wherein the engaging portion (R) ( 212 ) of the first restriction section ( 210 ) next to the connection carrier structure ( 408 ) is arranged.

Some of the advantages of the above modification of the seventh modification will now be described. The ports must be accurately located and stably fixed while the ink cartridge is inserted into the printer to ensure reliable electrical communication between the cartridge and the printer. Since the engaging portion of the first restricting portion is located adjacent to the terminal support structure, a positioning action of the first restricting portion comes close to the position where positioning is most needed (that is, at the terminals of the terminal support structure). The elastic force from the device side terminals can be appropriately counteracted. In addition, a positional shift of the terminals, which may occur due to vibration during printing operations, can be suppressed. Therefore, the arrangement of the terminals is more stable, whereby the stable electrical connection between the cartridge-side terminals and the device-side terminals is maintained.

In addition, since the lever is not integrally formed with the cartridge, the material for producing the cartridge may be different from the material used to manufacture the lever. In addition, the material of the cartridge may be selected with less regard to flexibility and durability requirements and with a greater attention to other properties, such as resistance to ink.

In addition, since the lever is not disposed on the cartridge, no special care is required to prevent creep of the lever during packing of the cartridge for transportation and distribution. This simplifies the packaging requirements and improves the user-friendliness. Since the lever is not an integral part of the cartridge, the cartridge can be made smaller.

This further enables size reduction of the packaging material, such as a paper or box, used to package the cartridge for transport or distribution of the cartridge, thereby advantageously reducing transport and component costs. In addition, since the lever is not formed integrally with the cartridge, the first cartridge-side restricting portion with a small size and simple structure and, for example, compared with those in US Publication No. 2005/0151811 described structures, higher rigidity are formed. As a result, the likelihood of plastic deformation of the first cartridge-side restricting portion is significantly reduced. In the attached or inserted state, the cartridge can be held in the proper position in the cartridge attachment structure, thereby maintaining normal or good contact between the cartridge side ports and the device side ports and reducing the likelihood of poor electrical communication. Since the first cartridge-side restricting portion may have a small size and a simple structure, unlike the cartridges of US Publication No. 2005/0151811, no special care is required in the package for transporting and distributing the cartridge to creep deformation of the lever to prevent. This reduces the packaging requirements and also improves the user-friendliness. It is possible that the structure connecting the cartridge terminals and the engaging portion of the cartridge with each other is only a rigid structure (which is not the case for the flexible levers of US Publication No. 2005/0151811). In this case, less vibration is transmitted from the engaging portion to the cartridge terminals, so that the electrical communication is more stable.

Since the connection plane (TP) of the terminals is neither parallel nor perpendicular to that through the front edge ( 288 ) defined plane (BP), the surface of the cartridge ports can be wiped properly during insertion of the cartridge into the printer. In addition, this design reduces or eliminates insulation debris (dust) that can be generated when the printer ports rub against the board for long periods of time during the mounting of the cartridge.

Since the printer terminals exert an elastic force on the cartridge terminals, which includes a vector component in the direction in which the cartridge is detached from the printer, there is no need to use a spring like the one in FIG U.S. Patent 6,955,422 described spring 103 provided. In other words, the elastic force from the printer-side terminals serves to press both the printer-side and cartridge-side terminals against each other and to move the cartridge in the direction for detaching from the printer when the engagement between the first restricting portion and the printer lever is released. Therefore, there is no need to provide an additional spring as in the case of US Pat. No. 6,955,422, thereby allowing a simpler structure and reduced costs.

As a result, since the first restricting portion is adapted to engage with the engaging portion of the lever so as to restrict the movement of the cartridge in the direction opposite to the mounting direction, the position of the cartridge terminals with respect to the mounting direction by the elastic Maintaining force of the device-side contact-forming elements and with respect to the direction opposite to the attachment direction by the first restriction portion when the cartridge is inserted into the printer. Since the cartridge terminals are "embedded" in this manner, they are firmly fixed against movement both in the mounting direction and in the direction opposite to the mounting direction. Therefore, there is less likelihood of misalignment or separation between the cartridge terminals and the device side contact-forming members as compared with the one-sided restriction by the elastic member 40 and the associated structure of the U.S. Patent No. 7,008,053 ,

Application 1

The ink cartridge as described above, wherein the connection plane (TP) is at an angle of between approximately 25 and 40 degrees to that through the leading edge (FIG. 288 ) defined level (BP).

How about the 42A - 45 is discussed, if the terminal plane is at an angle between approximately 25 and 40 degrees relative to the plane defined by the leading edge, excessive wiping is prevented and sufficient force for preventing half insertion can be exerted.

Application 2

The ink cartridge as described above, when the front side ( 203 ) of the cartridge body ( 20 ) is considered to be such that the ink feed structure ( 280 ) downwards, the engaging portion ( 212 ) of the first restriction section ( 210 ) to the left of a right edge of a rightmost terminal of the plurality of terminals ( 400 ) and to the right of a left edge of the leftmost terminal of the plurality of terminals ( 400 ) is arranged.

If the ink cartridge is attached to the printing device, if the cartridge is held too tight, contact with some of the device-side contact forming elements (for example, port 734 in the 31 ) not sure. By disposing the engaging portion of the first restricting portion to the left of a right edge of a rightmost terminal of the plurality of terminals and to the right of a left edge of the leftmost terminal of the plurality of terminals, the ink cartridge may tilt sufficiently so that the electrical connection between the plurality of terminals and the device side contact-forming elements can be even more stable.

Application 3

The ink cartridge as described above ( 20 ), which further comprises a second restriction section ( 220 ) on the back ( 204 ) of the ink cartridge ( 20 ), the second restriction section ( 220 ) is designed and set up with an appropriate section ( 620 ) of the inkjet printing device ( 50 ), and the distance (B) between the engaging portion of the second restricting portion (FIG. 220 ) and the front edge ( 288 ) defined plane (BP) is greater than the distance (A) between the engaging portion ( 212 ) of the first restriction section ( 210 ) and the front edge ( 288 ) defined plane (BP), when the distances in one to the through the leading edge ( 288 ) defined plane (BP) vertical direction.

When the engaging portion of the second restricting portion is located farther from the plane defined by the leading edge than the engaging portion of the first restricting portion, the likelihood that the first restricting portion is disengaged from the printer engaging portion can be further increased as compared with the case where the engaging portion of the first restricting portion from the plane defined by the leading edge than the engaging portion of the second restricting portion can be reduced more effectively.

Application 4

The ink cartridge as described above ( 20 ), when, when the ink cartridge ( 20 ) so from the side ( 203 ) is considered that the engaging portion ( 212 ) of the first restriction section ( 210 ) lies to the right and the ink feed structure ( 280 ) downwards, the distance (A) between the engagement portion ( 212 ) of the first restriction section ( 210 ) and the front edge ( 288 ) defined plane (BP) is smaller than the distance (C) between a pivot ( 800c ) of the lever ( 80 ) and the front edge ( 288 ) defined level (BP) when the cartridge ( 20 ) is mounted when the distances in one to the through the leading edge ( 288 ) defined plane (BP) vertical direction.

When the distance between the engaging portion of the first restricting portion and the plane defined by the leading edge is smaller than the distance between a pivot point of the lever and the plane defined by the leading edge when the cartridge is mounted, the lever serves to restrict the movement of the cartridge. This reduces the likelihood that the first restricting portion will be released or disengaged from the engaging portion of the lever, thereby creating a stable electrical connection between the plurality of terminals and the contact forming elements and reducing the likelihood of poor continuity. The first restriction portion may move about the rotation axis of the lever when a force is applied from the contact formation members to the attached cartridge. This reduces the likelihood that the engaging portion of the first restricting portion is decoupled from the engaging portion of the lever.

Application 5

The ink cartridge as described above, when the ink cartridge ( 20 ) so from the side ( 203 ) is considered that the engaging portion ( 212 ) of the first restriction section ( 210 ) lies to the right and the ink feed structure ( 280 ) downwards, the engaging portion ( 212 ) of the first restriction section ( 210 ) to the left of a pivot ( 800c ) of the lever is arranged when the cartridge is mounted.

When the cartridge is mounted such that the engaging portion of the first restricting portion is to the left of a pivot point of the lever, when the cartridge is viewed from the side so that the engaging portion of the first restricting portion is right and the ink supply structure is facing down, the first restricting portion generates a torque on the lever to rotate the lever about the axis of rotation of the lever in the direction opposite to the release direction. This reduces the likelihood that the engaging portion of the first restricting portion will be released from the engaging portion of the lever, and further ensures the stable electrical connection between the plural terminals and the apparatus-side contact forming members. Even if the cartridge receives a force, the first restriction portion would move with the cartridge. Such movement reduces the likelihood that the engaging portion of the first restricting portion will be released from the engaging portion of the lever.

Application 6

The ink cartridge as described above, when the front side ( 203 ) of the cartridge body ( 22 ) is considered to be such that the ink feed structure ( 280 ), at least a portion of the engaging portion (FIG. 212 ) of the first restriction section ( 210 ) substantially at the center of the ink cartridge ( 20 ) is arranged in the width direction.

By providing the first restricting portion in such a position that at least a portion of the engaging portion of the first restricting portion is located substantially at the center of the ink cartridge in the width direction, the first restricting portion is disposed extremely close to the plurality of terminals so that the electrical connection between the plurality of terminals and the device-side contact forming elements can be stable.

Application 7

An ink cartridge ( 20 ) designed to be detachable on an inkjet printing device ( 50 ), the inkjet printing device ( 50 ) a plurality of device-side contact-forming elements ( 731 - 739 ) designed and arranged to apply an elastic force (Pt) to the ink cartridge ( 20 ) when the ink cartridge ( 20 ) against the device-side contact-forming elements ( 731 - 739 ), and the inkjet printing device ( 50 ) also a lever ( 80 ) with an engaging portion ( 810 ), and the ink cartridge ( 20 ) comprises: a cartridge body ( 22 ), which has a first surface ( 203 ), a second surface ( 204 ), a third surface ( 202 ) and a fourth surface ( 201 ), wherein the first surface ( 203 ) and the second surface ( 204 ) face each other and the third surface ( 202 ) and the fourth surface ( 201 ) face each other; an electrical device; an ink chamber ( 200 ) for storing ink; one on the fourth surface ( 201 ) of the cartridge body ( 22 ) arranged ink supply structure ( 280 ) designed and arranged to remove ink from the ink chamber ( 200 ) to the inkjet printing device ( 50 ), the ink feed structure ( 280 ) an attachment direction (SD) leading edge ( 288 ) having a plane (BP) of the ink cartridge ( 20 ) Are defined; a connection carrier structure ( 408 ) close to the first surface ( 203 ) of the cartridge body ( 22 ), wherein the connection carrier structure ( 408 ) a plurality of electrically conductive connections coupled to the electrical device ( 400 ), and the Contact sections (cp) designed and at the contact section structure ( 408 ) are arranged to be connected to contact sections (cp) of the connections (cp) 400 ) with the contact-forming elements ( 731 - 739 ) and receive the elastic force (Pt) from them when the ink cartridge ( 20 ) on the printing device ( 50 ), the contact sections ( 400 ) are arranged essentially in a contact section plane (TP) which is neither parallel nor perpendicular to the plane of the front edge (TP) (FIG. 288 ) lies; and a first restriction section ( 210 ), which is designed with the engagement section ( 810 ) of the lever ( 80 ) to engage a movement of the ink cartridge ( 20 ) in a direction opposite to the attachment direction (SD) direction (RD), wherein the engaging portion (R) ( 212 ) of the first restriction section ( 210 ) next to the connection carrier structure ( 408 ) is arranged.

Some of the advantages of the above modification of the seventh modification will now be described. The ports must be accurately located and stably fixed while the ink cartridge is inserted into the printer to ensure reliable electrical communication between the cartridge and the printer. Since the engaging portion of the first restricting portion is located adjacent to the terminal support structure, a positioning action of the first restricting portion comes close to the position where positioning is most needed (that is, at the terminals of the terminal support structure). The elastic force from the device side terminals can be appropriately counteracted. In addition, a positional shift of the terminals, which may occur due to vibration during printing operations, can be suppressed. Therefore, the arrangement of the terminals is more stable, whereby the stable electrical connection between the cartridge-side terminals and the device-side terminals is maintained.

In addition, since the lever is not integrally formed with the cartridge, the material for producing the cartridge may be different from the material used to manufacture the lever. In addition, the material of the cartridge may be selected with less regard to flexibility and durability requirements and with a greater attention to other properties, such as resistance to ink.

In addition, since the lever is not disposed on the cartridge, no special care is required to prevent creep of the lever during packing of the cartridge for transportation and distribution. This simplifies the packaging requirements and improves the user-friendliness. Since the lever is not an integral part of the cartridge, the cartridge can be made smaller. This further enables size reduction of the packaging material, such as a paper or box, used to package the cartridge for transport or distribution of the cartridge, thereby advantageously reducing transport and component costs. In addition, since the lever is not formed integrally with the cartridge, the first cartridge-side restricting portion with a small size and simple structure and, for example, compared with those in US Publication No. 2005/0151811 described structures, higher rigidity are formed. As a result, the likelihood of plastic deformation of the first cartridge-side restricting portion is significantly reduced. In the attached or inserted state, the cartridge can be held in the proper position in the cartridge attachment structure, thereby maintaining normal or good contact between the cartridge side ports and the device side ports and reducing the likelihood of poor electrical communication. Since the first cartridge-side restricting portion may have a small size and a simple structure, unlike the cartridges of US Publication No. 2005/0151811, no special care is required in the package for transporting and distributing the cartridge to creep deformation of the lever to prevent. This reduces the packaging requirements and also improves the user-friendliness.

It is possible that the structure connecting the cartridge terminals and the engaging portion of the cartridge is only a rigid structure (which is for the flexible levers of the US Publication No. 2005/0151811 not the case). In this case, less vibration is transmitted from the engaging portion to the cartridge terminals, so that the electrical communication is more stable.

Since the contact section plane (TP) of the terminals is neither parallel nor perpendicular to that through the leading edge (FIG. 288 ) defined plane (BP), the surface of the cartridge ports can be wiped properly during insertion of the cartridge into the printer. In addition, this design reduces or eliminates insulation debris (dust) that can be generated when the printer ports rub against the board for long periods of time during the mounting of the cartridge.

Since the printer terminals exert an elastic force on the cartridge terminals, which includes a vector component in the direction in which the cartridge is detached from the printer, there is no need to use a spring like the one in FIG U.S. Patent 6,955,422 described spring 103 provided. In other words, the elastic force from the printer-side terminals serves to press both the printer-side and cartridge-side terminals against each other and to move the cartridge in the direction for detaching from the printer when the engagement between the first restricting portion and the printer lever is released. Therefore, there is no need to provide an additional spring as in the case of US Pat. No. 6,955,422, thereby allowing a simpler structure and reduced costs.

As a result, since the first restricting portion is adapted to engage with the engaging portion of the lever so as to restrict the movement of the cartridge in the direction opposite to the mounting direction, the position of the cartridge terminals with respect to the mounting direction by the elastic Maintaining force of the device-side contact-forming elements and with respect to the direction opposite to the attachment direction by the first restriction portion when the cartridge is inserted into the printer. Since the cartridge terminals are "embedded" in this manner, they are firmly fixed against movement both in the mounting direction and in the direction opposite to the mounting direction. Therefore, there is less likelihood of misalignment or separation between the cartridge terminals and the device side contact-forming members as compared with the one-sided restriction by the elastic member 40 and the associated structure of the U.S. Patent No. 7,008,053 ,

Application 1

The ink cartridge as described above, wherein the contact portion plane (TP) is at an angle of between approximately 25 and 40 degrees to that through the leading edge (FIG. 288 ) defined level (BP).

How about the 42A - 45 is discussed, if the contact portion plane is at an angle between approximately 25 and 40 degrees relative to the plane defined by the leading edge, excessive wiping is prevented and sufficient force for preventing half insertion can be exerted.

Application 2

The ink cartridge as described above, when the first surface ( 203 ) of the cartridge body ( 20 ) is considered to be such that the ink feed structure ( 280 ) downwards, the engaging portion ( 212 ) of the first restriction section ( 210 ) to the left of the rightmost contact portion of the plurality of terminals ( 400 ) and to the right of the leftmost contact portion of the plurality of terminals ( 400 ) is arranged.

If the ink cartridge is attached to the printing device, if the cartridge is held too tight, contact with some of the device-side contact forming elements (for example, port 734 in the 31 ) not sure. By disposing the engagement portion of the first restricting portion to the left of the rightmost contact portion of the plurality of terminals and to the right of the leftmost contact portion of the plurality of terminals, the ink cartridge may incline sufficiently so that the electrical connection between the plurality of terminals and the device side contact forming elements is even more stable can be.

Application 3

The ink cartridge as described above ( 20 ), which further comprises a second restriction section ( 220 ) on the second surface ( 204 ) of the ink cartridge ( 20 ), the second restriction section ( 220 ) is designed and set up with an appropriate section ( 620 ) of the inkjet printing device ( 50 ), and the distance (B) between the engaging portion of the second restricting portion (FIG. 220 ) and the front edge ( 288 ) defined plane (BP) is greater than the distance (A) between the engaging portion ( 212 ) of the first restriction section ( 210 ) and the front edge ( 288 ) defined plane (BP), when the distances in one to the through the leading edge ( 288 ) defined plane (BP) vertical direction.

When the engaging portion of the second restricting portion is located farther from the plane defined by the leading edge than the engaging portion of the first restricting portion, the likelihood that the first restricting portion is disengaged from the printer engaging portion can be further increased as compared with the case where the engaging portion of the first restricting portion from the plane defined by the leading edge than the engaging portion of the second restricting portion can be reduced more effectively.

Application 4

The ink cartridge as described above ( 20 ), when, when the ink cartridge ( 20 ) so from the side ( 203 ) is considered that the engaging portion ( 212 ) of the first restriction section ( 210 ) lies to the right and the ink feed structure ( 280 ) downwards, the distance (A) between the engagement portion ( 212 ) of the first Restriction section ( 210 ) and the front edge ( 288 ) defined plane (BP) is smaller than the distance (C) between a pivot ( 800c ) of the lever ( 80 ) and the front edge ( 288 ) defined level (BP) when the cartridge ( 20 ) is mounted when the distances in one to the through the leading edge ( 288 ) defined plane (BP) vertical direction.

When the distance between the engaging portion of the first restricting portion and the plane defined by the leading edge is smaller than the distance between a pivot point of the lever and the plane defined by the leading edge when the cartridge is mounted, the lever serves to move the cartridge restrict. This reduces the likelihood that the first restricting portion will be released or disengaged from the engaging portion of the lever, thereby creating a stable electrical connection between the plurality of terminals and the contact forming elements and reducing the likelihood of poor continuity. The first restriction portion may move about the rotation axis of the lever when a force is applied from the contact formation members to the attached cartridge. This reduces the likelihood that the engaging portion of the first restricting portion is decoupled from the engaging portion of the lever.

Application 5

The ink cartridge as described above, when the ink cartridge ( 20 ) so from the side ( 203 ) is considered that the engaging portion ( 212 ) of the first restriction section ( 210 ) lies to the right and the ink feed structure ( 280 ) downwards, the engaging portion ( 212 ) of the first restriction section ( 210 ) to the left of a pivot ( 800c ) of the lever is arranged when the cartridge is mounted.

When the cartridge is mounted such that the engaging portion of the first restricting portion is to the left of a pivot point of the lever, when the cartridge is viewed from the side so that the engaging portion of the first restricting portion is right and the ink supply structure is facing down, the first restricting portion generates a torque on the lever to rotate the lever about the axis of rotation of the lever in the direction opposite to the release direction. This reduces the likelihood that the engaging portion of the first restricting portion will be released from the engaging portion of the lever, and further ensures the stable electrical connection between the plural terminals and the apparatus-side contact forming members. Even if the cartridge receives a force, the first restriction portion would move with the cartridge. Such movement reduces the likelihood that the engaging portion of the first restricting portion will be released from the engaging portion of the lever.

Application 6

The ink cartridge as described above, when the first surface ( 203 ) of the cartridge body ( 22 ) is considered to be such that the ink feed structure ( 280 ), at least a portion of the engaging portion (FIG. 212 ) of the first restriction section ( 210 ) substantially at the center of the ink cartridge ( 20 ) is arranged in the width direction.

By providing the first restricting portion in such a position that at least a portion of the engaging portion of the first restricting portion is located substantially at the center of the ink cartridge in the width direction, the first restricting portion is disposed extremely close to the plurality of terminals so that the electrical connection between the plurality of terminals and the device-side contact forming elements can be stable.

Application 7

The ink cartridge as described above, in which the ink through the leading edge ( 288 ) defined plane (BP) substantially with the fourth surface ( 201 ) is flush.

As a result, since the first restricting portion is engaged with the engagement portion of the lever so as to restrict the movement of the cartridge in the direction opposite to the attachment direction, the position of the cartridge ports with respect to the attachment direction is determined by the elastic force of the device side contact forming elements and with respect to the direction opposite to the mounting direction by the first restricting portion maintained when the cartridge is inserted into the printer. Since the cartridge terminals are "embedded" in this manner, they are firmly fixed against movement both in the mounting direction and in the direction opposite to the mounting direction. Therefore, there is less likelihood of misalignment or separation between the cartridge terminals and the device side contact-forming members as compared with the one-sided restriction by the elastic member 40 and the associated structure of the U.S. Patent No. 7,008,053 ,

Application 1

The combination as described above, wherein the contact portion plane (TP) is at an angle of between approximately 25 and 40 degrees to that through the leading edge (FIG. 288 ) defined level (BP).

How about the 42A - 45 is discussed, if the contact portion plane is at an angle between approximately 25 and 40 degrees relative to the plane defined by the leading edge, excessive wiping is prevented and sufficient force for preventing half insertion can be exerted.

Application 2

The combination as described above, when the front side ( 203 ) of the cartridge body ( 20 ) is considered to be such that the ink feed structure ( 280 ) downwards, the engaging portion ( 212 ) of the first restriction section ( 210 ) to the left of the rightmost contact portion of the plurality of terminals ( 400 ) and to the right of the leftmost contact portion of the plurality of terminals ( 400 ) is arranged.

If the ink cartridge is attached to the printing device, if the cartridge is held too tight, contact with some of the device-side contact forming elements (for example, port 734 in the 31 ) not sure. By disposing the engagement portion of the first restricting portion to the left of the rightmost contact portion of the plurality of terminals and to the right of the leftmost contact portion of the plurality of terminals, the ink cartridge may incline sufficiently so that the electrical connection between the plurality of terminals and the device side contact forming elements becomes even more stable can be.

Application 3

The combination as described above, further comprising a second restriction section ( 220 ) on the back ( 204 ) of the ink cartridge ( 20 ), the second restriction section ( 220 ) with a corresponding section ( 620 ) of the inkjet printing device ( 50 ), and the distance (B) between the engaging portion of the second restricting portion (FIG. 220 ) and the front edge ( 288 ) defined plane (BP) is greater than the distance (A) between the engaging portion ( 212 ) of the first restriction section ( 210 ) and the front edge ( 288 ) defined plane (BP), when the distances in one to the through the leading edge ( 288 ) defined plane (BP) vertical direction.

When the engaging portion of the second restricting portion is located farther from the plane defined by the leading edge than the engaging portion of the first restricting portion, the probability that the first restricting portion is released from the printer engaging portion can be compared with the case. that the engaging portion of the first restricting portion is farther from the plane defined by the leading edge than the engaging portion of the second restricting portion is more effectively reduced.

Application 4

The combination as described above, in which the lever ( 80 ) two ends and a pivot point ( 800c ) between the two ends and, when the ink cartridge ( 20 ) so from the side ( 203 ) is considered that the engaging portion ( 212 ) of the first restriction section ( 210 ) lies to the right and the ink feed structure ( 280 ) downwards, the distance (A) between the engagement portion ( 212 ) of the first restriction section ( 210 ) and the front edge ( 288 ) defined plane (BP) is smaller than the distance (C) between the pivot ( 800c ) of the lever ( 80 ) and the front edge ( 288 ) defined level (BP) when the cartridge ( 20 ) is mounted when the distances in one to the through the leading edge ( 288 ) defined plane (BP) vertical direction.

When the distance between the engaging portion of the first restricting portion and the plane defined by the leading edge is smaller than the distance between a pivot point of the lever and the plane defined by the leading edge when the cartridge is mounted, the lever serves to move the cartridge restrict. This reduces the likelihood that the first restricting portion will be released or disengaged from the engaging portion of the lever, thereby creating a stable electrical connection between the plurality of terminals and the contact forming elements and reducing the likelihood of poor continuity. The first restriction portion may move about the rotation axis of the lever when a force is applied from the contact formation members to the attached cartridge. This reduces the likelihood that the engaging portion of the first restricting portion is decoupled from the engaging portion of the lever.

Application 5

The combination as described above, in which the lever ( 80 ) two ends and a pivot point ( 800c ) between the two ends and, when the ink cartridge ( 20 ) so from the side ( 203 ) is considered that the engaging portion ( 212 ) of the first restriction section ( 210 ) lies to the right and the ink feed structure ( 280 ) downwards, the engaging portion ( 212 ) of the first restriction section ( 210 ) to the left of the pivot ( 800c ) of the lever is arranged.

When the cartridge is mounted such that the engaging portion of the first restricting portion is to the left of a pivot point of the lever, when the cartridge is viewed from the side so that the engaging portion of the first restricting portion is right and the ink supply structure is facing down, the first restricting portion generates a torque on the lever to rotate the lever about the axis of rotation of the lever in the direction opposite to the release direction. This reduces the likelihood that the engaging portion of the first restricting portion will be released from the engaging portion of the lever, and further ensures the stable electrical connection between the plural terminals and the apparatus-side contact forming members. Even if the cartridge receives a force, the first restriction portion would move with the cartridge. Such movement reduces the likelihood that the engaging portion of the first restricting portion will be released from the engaging portion of the lever.

Application 6

The combination as described above, when the front side ( 203 ) of the cartridge body ( 22 ) is considered to be such that the ink feed structure ( 280 ), at least a portion of the engaging portion (FIG. 212 ) of the first restriction section ( 210 ) substantially at the center of the ink cartridge ( 20 ) is arranged in the width direction.

By providing the first restricting portion in such a position that at least a portion of the engaging portion of the first restricting portion is located substantially at the center of the ink cartridge in the width direction, the first restricting portion is disposed extremely close to the plurality of terminals so that the electrical connection between the plurality of terminals and the device-side contact forming elements can be stable.

Application 7

The combination as described above, in which the front edge ( 288 ) defined plane (BP) substantially at the lower end ( 201 ) is flush.

G-7-6. Sixth change

A combination of an ink cartridge ( 20 ) and a portion of an ink jet printing device ( 50 ), the combination comprising: a portion of an ink jet printing device ( 50 ), the section comprising: a plurality of device side Contact formation elements ( 731 - 739 ), which has an elastic force (Pt) on the ink cartridge ( 20 ) exercise; and a lever ( 80 ) with an engaging portion ( 810 ); an ink cartridge ( 20 ), the ink cartridge ( 20 ) comprises: a cartridge body ( 22 ), which has a front side ( 203 ), a back ( 204 ), an upper end ( 202 ) and a lower end ( 201 ), the front side ( 203 ) and the back ( 204 ) are opposite each other and the upper end ( 202 ) and the lower end ( 201 ) face each other; an electrical device, an ink chamber ( 200 ) for storing ink; one at the lower end ( 201 ) of the cartridge body ( 22 ) arranged ink supply structure ( 280 ) designed and arranged to remove ink from the ink chamber ( 200 ) to the inkjet printing device ( 50 ), the ink feed structure ( 280 ) an attachment direction (SD) leading edge ( 288 ) having a plane (BP) of the ink cartridge ( 20 ) Are defined; a connection carrier structure ( 408 ), which are close to the front ( 203 ) of the cartridge body ( 22 ), wherein the connection carrier structure ( 408 ) a plurality of electrically conductive connections coupled to the electrical device ( 400 ), the connections ( 400 ) on the connection carrier structure ( 408 ) with the contact-forming elements ( 731 - 739 ) and receive the elastic force (Pt) from them, and the terminals ( 400 ) are arranged substantially in a connection plane (TP) which is neither parallel nor perpendicular to the plane of the front edge (TP). 288 ) lies; and a first restriction section ( 210 ) connected to the engaging section ( 810 ) of the lever ( 80 ) is engaged so as to move the ink cartridge ( 20 ) in a direction opposite to the attachment direction (SD) direction (RD), wherein the engaging portion (R) ( 212 ) of the first restriction section ( 210 ) next to the connection carrier structure ( 408 ) is arranged.

Some of the advantages of the above modification of the seventh modification will now be described. The ports must be accurately located and stably fixed while the ink cartridge is inserted into the printer to ensure reliable electrical communication between the cartridge and the printer. Since the engaging portion of the first restricting portion is located adjacent to the terminal support structure, a positioning action of the first restricting portion comes close to the position where positioning is most needed (that is, at the terminals of the terminal support structure). The elastic force from the device side terminals can be appropriately counteracted. In addition, a positional shift of the terminals, which may occur due to vibration during printing operations, can be suppressed. Therefore, the arrangement of the terminals is more stable, whereby the stable electrical connection between the cartridge-side terminals and the device-side terminals is maintained.

In addition, since the lever is not integrally formed with the cartridge, the material for producing the cartridge may be different from the material used to manufacture the lever. In addition, the material of the cartridge may be selected with less regard to flexibility and durability requirements and with a greater attention to other properties, such as resistance to ink.

In addition, since the lever is not disposed on the cartridge, no special care is required to prevent creep of the lever during packing of the cartridge for transportation and distribution. This simplifies the packaging requirements and improves the user-friendliness. Since the lever is not an integral part of the cartridge, the cartridge can be made smaller. This further enables size reduction of the packaging material, such as a paper or box, used to package the cartridge for transport or distribution of the cartridge, thereby advantageously reducing transport and component costs. In addition, since the lever is not formed integrally with the cartridge, the first cartridge-side restricting portion with a small size and simple structure and, for example, compared with those in US Publication No. 2005/0151811 described structures, higher rigidity are formed. As a result, the likelihood of plastic deformation of the first cartridge-side restricting portion is significantly reduced. In the attached or inserted state, the cartridge can be held in the proper position in the cartridge attachment structure, thereby maintaining normal or good contact between the cartridge side ports and the device side ports and reducing the likelihood of poor electrical communication. Since the first cartridge-side restricting portion may have a small size and a simple structure, unlike the cartridges of US Publication No. 2005/0151811, no special care is required in the package for transporting and distributing the cartridge to creep deformation of the lever to prevent. This reduces the packaging requirements and also improves the user-friendliness.

It is possible that the structure connecting the cartridge terminals and the engaging portion of the cartridge is only a rigid structure (which is for the flexible levers of the US Publication No. 2005/0151811 not the case). In this case, less vibration from the Transferring engagement portion to the cartridge terminals, so that the electrical communication is more stable.

Since the connection plane (TP) of the terminals is neither parallel nor perpendicular to that through the front edge ( 288 ) defined plane (BP), the surface of the cartridge ports can be wiped properly during insertion of the cartridge into the printer. In addition, this design reduces or eliminates insulation debris (dust) that can be generated when the printer ports rub against the board for long periods of time during the mounting of the cartridge.

Since the printer terminals exert an elastic force on the cartridge terminals, which includes a vector component in the direction in which the cartridge is detached from the printer, there is no need to use a spring like the one in FIG U.S. Patent 6,955,422 described spring 103 provided. In other words, the elastic force from the printer-side terminals serves to press both the printer-side and cartridge-side terminals against each other and to move the cartridge in the direction for detaching from the printer when the engagement between the first restricting portion and the printer lever is released. Therefore, there is no need to provide an additional spring as in the case of US Pat. No. 6,955,422, thereby allowing a simpler structure and reduced costs.

As a result, since the first restricting portion is engaged with the engagement portion of the lever so as to restrict the movement of the cartridge in the direction opposite to the attachment direction, the position of the cartridge ports with respect to the attachment direction is determined by the elastic force of the device side contact forming elements and with respect to the direction opposite to the mounting direction by the first restricting portion maintained when the cartridge is inserted into the printer. Since the cartridge terminals are "embedded" in this manner, they are firmly fixed against movement both in the mounting direction and in the direction opposite to the mounting direction. Therefore, there is less likelihood of misalignment or separation between the cartridge terminals and the device side contact-forming members as compared with the one-sided restriction by the elastic member 40 and the associated structure of the U.S. Patent No. 7,008,053 ,

Application 1

The combination as described above, wherein the connection plane (TP) is at an angle of between approximately 25 and 40 degrees to that through the leading edge (TP). 288 ) defined level (BP).

How about the 42A - 45 is discussed, if the terminal plane is at an angle between approximately 25 and 40 degrees relative to the plane defined by the leading edge, excessive wiping is prevented and sufficient force for preventing half insertion can be exerted.

Application 2

The combination as described above, when the front side ( 203 ) of the cartridge body ( 20 ) is considered to be such that the ink feed structure ( 280 ) downwards, the engaging portion ( 212 ) of the first restriction section ( 210 ) to the left of a right edge of a rightmost terminal of the plurality of terminals ( 400 ) and to the right of a left edge of the leftmost terminal of the plurality of terminals ( 400 ) is arranged.

If the ink cartridge is attached to the printing device, if the cartridge is held too tight, contact with some of the device-side contact forming elements (for example, port 734 in the 31 ) not sure. By disposing the engaging portion of the first restricting portion to the left of a right edge of a rightmost terminal of the plurality of terminals and to the right of a left edge of the leftmost terminal of the plurality of terminals, the ink cartridge may tilt sufficiently so that the electrical connection between the plurality of terminals and the device side contact-forming elements can be even more stable.

Application 3

The combination as described above, further comprising a second restriction section ( 220 ) on the back ( 204 ) of the ink cartridge ( 20 ), the second restriction section ( 220 ) with a corresponding section ( 620 ) of the inkjet printing device ( 50 ) and the distance (B) between the engaging portion of the second restricting portion (FIG. 220 ) and the front edge ( 288 ) defined plane (BP) is greater than the distance (A) between the engaging portion ( 212 ) of the first restriction section ( 210 ) and the front edge ( 288 ) defined plane (BP), when the distances in one to the through the leading edge ( 288 ) defined plane (BP) vertical direction.

When the engagement portion of the second restriction portion farther from that through the Front edge defined plane is arranged as the engagement portion of the first restriction portion, the probability that the first restriction portion is released from the pressure engagement portion compared to the case that the engagement portion of the first restriction portion is farther away from the plane defined by the leading edge than the Engaging portion of the second restricting portion can be reduced more effectively.

Application 4

The combination as described above, in which the lever ( 80 ) two ends and a pivot point ( 800c ) between the two ends and, when the ink cartridge ( 20 ) so from the side ( 203 ) is considered that the engaging portion ( 212 ) of the first restriction section ( 210 ) lies to the right and the ink feed structure ( 280 ) downwards, the distance (A) between the engagement portion ( 212 ) of the first restriction section ( 210 ) and the front edge ( 288 ) defined plane (BP) is smaller than the distance (C) between the pivot ( 800c ) of the lever ( 80 ) and the front edge ( 288 ) defined level (BP) when the cartridge ( 20 ) is mounted when the distances in one to the through the leading edge ( 288 ) defined plane (BP) vertical direction.

When the distance between the engaging portion of the first restricting portion and the plane defined by the leading edge is smaller than the distance between a pivot point of the lever and the plane defined by the leading edge when the cartridge is mounted, the lever serves to move the cartridge restrict. This reduces the likelihood that the first restricting portion will be released or disengaged from the engaging portion of the lever, thereby creating a stable electrical connection between the plurality of terminals and the contact forming elements and reducing the likelihood of poor continuity. The first restriction portion may move about the rotation axis of the lever when a force is applied from the contact formation members to the attached cartridge. This reduces the likelihood that the engaging portion of the first restricting portion is decoupled from the engaging portion of the lever.

Application 5

The combination as described above, in which the lever ( 80 ) two ends and a pivot point ( 800c ) between the two ends and, when the ink cartridge ( 20 ) so from the side ( 203 ) is considered that the engaging portion ( 212 ) of the first restriction section ( 210 ) lies to the right and the ink feed structure ( 280 ) downwards, the engaging portion ( 212 ) of the first restriction section ( 210 ) to the left of the pivot ( 800c ) of the lever is arranged.

When the cartridge is mounted such that the engaging portion of the first restricting portion is to the left of a pivot point of the lever, when the cartridge is viewed from the side so that the engaging portion of the first restricting portion is right and the ink supply structure is facing down, the first restricting portion generates a torque on the lever to rotate the lever about the axis of rotation of the lever in the direction opposite to the release direction. This reduces the likelihood that the engaging portion of the first restricting portion will be released from the engaging portion of the lever, and further ensures the stable electrical connection between the plural terminals and the apparatus-side contact forming members. Even if the cartridge receives a force, the first restriction portion would move with the cartridge. Such movement reduces the likelihood that the engaging portion of the first restricting portion will be released from the engaging portion of the lever.

The combination as described above, when the front side ( 203 ) of the cartridge body ( 22 ) is considered to be such that the ink feed structure ( 280 ), at least a portion of the engaging portion (FIG. 212 ) of the first restriction section ( 210 ) substantially at the center of the ink cartridge ( 20 ) is arranged in the width direction.

By providing the first restricting portion in such a position that at least a portion of the engaging portion of the first restricting portion is located substantially at the center of the ink cartridge in the width direction, the first restricting portion is disposed extremely close to the plurality of terminals so that the electrical connection between the plurality of terminals and the device-side contact forming elements can be stable.

How about the 42A - 45 is discussed, if the contact portion plane is at an angle between approximately 25 and 40 degrees relative to the plane defined by the leading edge, excessive wiping is prevented and sufficient force for preventing half insertion can be exerted.

Application 2

The combination as described above, when the first surface ( 203 ) of the cartridge body ( 20 ) is considered to be such that the ink feed structure ( 280 ) downwards, the engaging portion ( 212 ) of the first restriction section ( 210 ) to the left of the rightmost contact portion of the plurality of terminals ( 400 ) and to the right of the leftmost contact portion of the plurality of terminals ( 400 ) is arranged.

If the ink cartridge is attached to the printing device, if the cartridge is held too tight, contact with some of the device-side contact forming elements (for example, port 734 in the 31 ) not sure. By disposing the engagement portion of the first restricting portion to the left of the rightmost contact portion of the plurality of terminals and to the right of the leftmost contact portion of the plurality of terminals, the ink cartridge may incline sufficiently so that the electrical connection between the plurality of terminals and the device side contact forming elements becomes even more stable can be.

Application 3

The combination as described above, further comprising a second restriction section ( 220 ) on the second surface ( 204 ) of the ink cartridge ( 20 ), the second restriction section ( 220 ) with a corresponding section ( 620 ) of the inkjet printing device ( 50 ) and the distance (B) between the engaging portion of the second restricting portion (FIG. 220 ) and the front edge ( 288 ) defined plane (BP) is greater than the distance (A) between the Engaging section ( 212 ) of the first restriction section ( 210 ) and the front edge ( 288 ) defined plane (BP), when the distances in one to the through the leading edge ( 288 ) defined plane (BP) vertical direction.

When the engaging portion of the second restricting portion is located farther from the plane defined by the leading edge than the engaging portion of the first restricting portion, the likelihood that the first restricting portion is disengaged from the printer engaging portion can be further increased as compared with the case where the engaging portion of the first restricting portion from the plane defined by the leading edge than the engaging portion of the second restricting portion can be reduced more effectively.

Application 4

The combination as described above, in which the lever ( 80 ) two ends and a pivot point ( 800c ) between the two ends and, when the ink cartridge ( 20 ) so from the side ( 203 ) is considered that the engaging portion ( 212 ) of the first restriction section ( 210 ) lies to the right and the ink feed structure ( 280 ) downwards, the distance (A) between the engagement portion ( 212 ) of the first restriction section ( 210 ) and the front edge ( 288 ) defined plane (BP) is smaller than the distance (C) between the pivot ( 800c ) of the lever ( 80 ) and the front edge ( 288 ) defined level (BP) when the cartridge ( 20 ) is mounted when the distances in one to the through the leading edge ( 288 ) defined plane (BP) vertical direction.

When the distance between the engaging portion of the first restricting portion and the plane defined by the leading edge is smaller than the distance between a pivot point of the lever and the plane defined by the leading edge when the cartridge is mounted, the lever serves to move the cartridge restrict. This reduces the likelihood that the first restricting portion will be released or disengaged from the engaging portion of the lever, thereby creating a stable electrical connection between the plurality of terminals and the contact forming elements and reducing the likelihood of poor continuity. The first restriction portion may move about the rotation axis of the lever when a force is applied from the contact formation members to the attached cartridge. This reduces the likelihood that the engaging portion of the first restricting member is decoupled from the engaging portion of the lever.

When the cartridge is mounted such that the engaging portion of the first restricting portion is to the left of a pivot point of the lever, when the cartridge is viewed from the side so that the engaging portion of the first restricting portion is right and the ink supply structure is facing down, the first restricting portion generates a torque on the lever to rotate the lever about the axis of rotation of the lever in the direction opposite to the release direction. This reduces the likelihood that the engaging portion of the first restricting portion will be released from the engaging portion of the lever, and further ensures the stable electrical connection between the plural terminals and the apparatus-side contact forming members. Even if the cartridge receives a force, the first restriction portion would move with the cartridge. Such movement reduces the likelihood that the engaging portion of the first restricting portion will be released from the engaging portion of the lever.

G-7-8. Eighth change

A combination of an ink cartridge ( 20 ) and a portion of an ink jet printing device ( 50 ), the combination comprising: a portion of an ink jet printing device ( 50 ), the section comprising: a plurality of device-side contact-forming elements ( 731 - 739 ), which has an elastic force (Pt) on the ink cartridge ( 20 ) exercise; and a lever ( 80 ) with an engaging portion ( 810 ); an ink cartridge ( 20 ), the ink cartridge ( 20 ) comprises: a cartridge body ( 22 ), which has a first surface ( 203 ), a second surface ( 204 ), a third surface ( 202 ) and a fourth surface ( 201 ), wherein the first surface ( 203 ) and the second surface ( 204 ) face each other and the third surface ( 202 ) and the fourth surface ( 201 ) face each other; an electrical device, an ink chamber ( 200 ) for storing ink; one on the fourth surface ( 201 ) of the cartridge body ( 22 ) arranged ink supply structure ( 280 ) designed and arranged to remove ink from the ink chamber ( 200 ) to the inkjet printing device ( 50 ), the ink feed structure ( 280 ) an attachment direction (SD) leading edge ( 288 ) having a plane (BP) of the ink cartridge ( 20 ) Are defined; a connection carrier structure ( 408 ) close to the first surface ( 203 ) of the cartridge body ( 22 ), wherein the connection carrier structure ( 408 ) a plurality of electrically conductive connections coupled to the electrical device ( 400 ), the connections ( 400 ) on the connection carrier structure ( 408 ) with the contact-forming elements ( 731 - 739 ) and receive the elastic force (Pt) from them, and the terminals ( 400 ) are arranged substantially in a connection plane (TP) which is neither parallel nor perpendicular to the plane of the front edge (TP). 288 ) lies; and a first restriction section ( 210 ), which has an engagement section ( 212 ), which is connected to the engagement section ( 810 ) of the lever ( 80 ) is engaged so as to move the ink cartridge ( 20 ) in a direction opposite to the attachment direction (SD) direction (RD), wherein the engaging portion (R) ( 212 ) of the first restriction section ( 210 ) next to the connection carrier structure ( 408 ) is arranged.

Some of the advantages of the above modification of the seventh modification will now be described. The ports must be accurately located and stably fixed while the ink cartridge is inserted into the printer to ensure reliable electrical communication between the cartridge and the printer. Since the engaging portion of the first restricting portion is located adjacent to the terminal support structure, a positioning action of the first restricting portion comes close to the position where positioning is most needed (that is, at the terminals of the terminal support structure). The elastic force from the device side terminals can be appropriately counteracted. In addition, a positional shift of the terminals, which may occur due to vibration during printing operations, can be suppressed. Therefore, the arrangement of the terminals is more stable, whereby the stable electrical connection between the cartridge-side terminals and the device-side terminals is maintained.

In addition, since the lever is not integrally formed with the cartridge, the material for producing the cartridge may be different from the material used to manufacture the lever. In addition, the material of the cartridge may be selected with less regard to flexibility and durability requirements and with a greater attention to other properties, such as resistance to ink.

In addition, since the lever is not disposed on the cartridge, no special care is required to prevent creep of the lever during packing of the cartridge for transportation and distribution. This simplifies the packaging requirements and improves the user-friendliness. Since the lever is not an integral part of the cartridge, the cartridge can be made smaller. This further enables size reduction of the packaging material, such as a paper or box, used to package the cartridge for transport or distribution of the cartridge, thereby advantageously reducing transport and component costs. In addition, since the lever is not formed integrally with the cartridge, the first cartridge-side restricting portion with a small size and simple structure and, for example, compared with those in US Publication No. 2005/0151811 described structures, higher rigidity are formed. As a result, the likelihood of plastic deformation of the first cartridge-side restricting portion is significantly reduced. In the mounted or deployed state, the cartridge may be held in the proper position in the cartridge attachment structure, thereby maintaining normal or good contact between the cartridge side ports and the device side ports, and reducing the likelihood of poor electrical performance Communication is reduced. Since the first cartridge-side restricting portion may have a small size and a simple structure, unlike the cartridges of US Publication No. 2005/0151811, no special care is required in the package for transporting and distributing the cartridge to creep deformation of the lever to prevent. This reduces the packaging requirements and also improves the user-friendliness.

It is possible that the structure connecting the cartridge terminals and the engaging portion of the cartridge is only a rigid structure (which is for the flexible levers of the US Publication No. 2005/0151811 not the case). In this case, less vibration is transmitted from the engaging portion to the cartridge terminals, so that the electrical communication is more stable.

Since the connection plane (TP) of the terminals is neither parallel nor perpendicular to that through the front edge ( 288 ) defined plane (BP), the surface of the cartridge ports can be wiped properly during insertion of the cartridge into the printer. In addition, this design reduces or eliminates insulation debris (dust) that can be generated when the printer ports rub against the board for long periods of time during the mounting of the cartridge.

Since the printer terminals exert an elastic force on the cartridge terminals, which includes a vector component in the direction in which the cartridge is detached from the printer, there is no need to use a spring like the one in FIG U.S. Patent 6,955,422 described spring 103 provided. In other words, the elastic force from the printer-side terminals serves to press both the printer-side and cartridge-side terminals against each other and to move the cartridge in the direction for detaching from the printer when the engagement between the first restricting portion and the printer lever is released. Therefore, there is no need to provide an additional spring as in the case of US Pat. No. 6,955,422, thereby allowing a simpler structure and reduced costs.

As a result, since the first restricting portion is engaged with the engagement portion of the lever so as to restrict the movement of the cartridge in the direction opposite to the attachment direction, the position of the cartridge ports with respect to the attachment direction is determined by the elastic force of the device side contact forming elements and with respect to the direction opposite to the mounting direction by the first restricting portion maintained when the cartridge is inserted into the printer. Since the cartridge terminals are "embedded" in this manner, they are firmly fixed against movement both in the mounting direction and in the direction opposite to the mounting direction. Therefore, there is less likelihood of misalignment or separation between the cartridge terminals and the device side contact-forming members as compared with the one-sided restriction by the elastic member 40 and the associated structure of the U.S. Patent No. 7,008,053 ,

Application 1

The combination as described above, wherein the connection plane (TP) is at an angle of between approximately 25 and 40 degrees to that through the leading edge (TP). 288 ) defined level (BP).

How about the 42A - 45 is discussed, if the terminal plane is at an angle between approximately 25 and 40 degrees relative to the plane defined by the leading edge, excessive wiping is prevented and sufficient force for preventing half insertion can be exerted.

Application 2

The combination as described above, when the front side ( 203 ) of the cartridge body ( 20 ) is considered to be such that the ink feed structure ( 280 ) downwards, the engaging portion ( 212 ) of the first restriction section ( 210 ) to the left of a right edge of a rightmost terminal of the plurality of terminals ( 400 ) and to the right of a left edge of the leftmost terminal of the plurality of terminals ( 400 ) is arranged.

If the ink cartridge is attached to the printing device, if the cartridge is held too tight, contact with some of the device-side contact forming elements (for example, port 734 in the 31 ) not sure. By disposing the engaging portion of the first restricting portion to the left of a right edge of a rightmost terminal of the plurality of terminals and to the right of a left edge of the leftmost terminal of the plurality of terminals, the ink cartridge may tilt sufficiently so that the electrical connection between the plurality of terminals and the device side contact-forming elements can be even more stable.

Application 3

The combination as described above, further comprising a second restriction section ( 220 ) on the second surface ( 204 ) of the Ink cartridge ( 20 ), the second restriction section ( 220 ) with a corresponding section ( 620 ) of the inkjet printing device ( 50 ) and the distance (B) between the engaging portion of the second restricting portion (FIG. 220 ) and the front edge ( 288 ) defined plane (BP) is greater than the distance (A) between the engaging portion ( 212 ) of the first restriction section ( 210 ) and the front edge ( 288 ) defined plane (BP), when the distances in one to the through the leading edge ( 288 ) defined plane (BP) vertical direction.

When the engaging portion of the second restricting portion is located farther from the plane defined by the leading edge than the engaging portion of the first restricting portion, the likelihood that the first restricting portion is disengaged from the printer engaging portion can be further increased as compared with the case where the engaging portion of the first restricting portion from the plane defined by the leading edge than the engaging portion of the second restricting portion can be reduced more effectively.

Application 4

The combination as described above, in which the lever ( 80 ) two ends and a pivot point ( 800c ) between the two ends and, when the ink cartridge ( 20 ) so from the side ( 203 ) is considered that the engaging portion ( 212 ) of the first restriction section ( 210 ) lies to the right and the ink feed structure ( 280 ) downwards, the distance (A) between the engagement portion ( 212 ) of the first restriction section ( 210 ) and the front edge ( 288 ) defined plane (BP) is smaller than the distance (C) between the pivot ( 800c ) of the lever ( 80 ) and the front edge ( 288 ) defined level (BP) when the cartridge ( 20 ) is mounted when the distances in one to the through the leading edge ( 288 ) defined plane (BP) vertical direction.

When the distance between the engaging portion of the first restricting portion and the plane defined by the leading edge is smaller than the distance between a pivot point of the lever and the plane defined by the leading edge when the cartridge is mounted, the lever serves to move the cartridge restrict. This reduces the likelihood that the first restricting portion will be released or disengaged from the engaging portion of the lever, thereby creating a stable electrical connection between the plurality of terminals and the contact forming elements and reducing the likelihood of poor continuity. The first restriction portion may move about the rotation axis of the lever when a force is applied from the contact formation members to the attached cartridge. This reduces the likelihood that the engaging portion of the first restricting portion is decoupled from the engaging portion of the lever.

Application 5

The combination as described above, in which the lever ( 80 ) two ends and a pivot point ( 800c ) between the two ends and, when the ink cartridge ( 20 ) so from the side ( 203 ) is considered that the engaging portion ( 212 ) of the first restriction section ( 210 ) lies to the right and the ink feed structure ( 280 ) downwards, the engaging portion ( 212 ) of the first restriction section ( 210 ) to the left of the pivot ( 800c ) of the lever is arranged.

When the cartridge is mounted such that the engaging portion of the first restricting portion is to the left of a pivot point of the lever, when the cartridge is viewed from the side so that the engaging portion of the first restricting portion is right and the ink supply structure is facing down, the first restricting portion generates a torque on the lever to rotate the lever about the axis of rotation of the lever in the direction opposite to the release direction. This reduces the likelihood that the engaging portion of the first restricting portion will be released from the engaging portion of the lever, and further ensures the stable electrical connection between the plural terminals and the apparatus-side contact forming members. Even if the cartridge receives a force, the first restriction portion would move with the cartridge. Such movement reduces the likelihood that the engaging portion of the first restricting portion will be released from the engaging portion of the lever.

In addition, since the lever is not formed integrally with the cartridge, the first cartridge-side restricting portion with a small size and simple structure and, for example, compared with those in US Publication No. 2005/0151811 described structures, higher rigidity are formed. As a result, the likelihood of plastic deformation of the first cartridge-side restricting portion is significantly reduced. In the attached or inserted state, the cartridge can be held in the proper position in the cartridge attachment structure, thereby maintaining normal or good contact between the cartridge side ports and the device side ports and reducing the likelihood of poor electrical communication. Since the first cartridge-side restricting portion may have a small size and a simple structure, unlike the cartridges of US Publication No. 2005/0151811, no special care is required in the package for transporting and distributing the cartridge to creep deformation of the lever to prevent. This reduces the packaging requirements and also improves the user-friendliness.

It is possible that the structure connecting the cartridge terminals and the engaging portion of the cartridge is only a rigid structure (which is for the flexible levers of the US Publication No. 2005/0151811 not the case). In this case, less vibration is transmitted from the engaging portion to the cartridge terminals, so that the electrical communication is more stable.

Since the connection plane (TP) of the terminals is neither parallel nor perpendicular to that through the front edge ( 288 ) defined plane (BP), the surface of the cartridge ports can be wiped properly during insertion of the cartridge into the printer. In addition, this design reduces or eliminates insulation debris (dust) that can be generated when the printer ports rub against the board for long periods of time during the mounting of the cartridge.

Since the printer terminals exert an elastic force on the cartridge terminals, which includes a vector component in the direction in which the cartridge is detached from the printer, there is no need to use a spring like the one in FIG U.S. Patent 6,955,422 described spring 103 provided. In other words, the elastic force from the printer-side terminals serves to press both the printer-side and cartridge-side terminals together and to move the cartridge in the direction for detaching from the printer when the engagement between the first restricting portion and the printer lever is released becomes. Therefore, there is no need to provide an additional spring as in the case of US Pat. No. 6,955,422, thereby allowing a simpler structure and reduced costs.

As a result, since the first restricting portion is adapted to engage with the engaging portion of the lever so as to restrict the movement of the cartridge in the direction opposite to the mounting direction, the position of the cartridge terminals with respect to the mounting direction by the elastic Maintaining force of the device-side contact-forming elements and with respect to the direction opposite to the attachment direction by the first restriction portion when the cartridge is inserted into the printer. Since the cartridge terminals are "embedded" in this manner, they are firmly fixed against movement both in the mounting direction and in the direction opposite to the mounting direction. Therefore, there is less likelihood of misalignment or separation between the cartridge terminals and the device side contact-forming members as compared with the one-sided restriction by the elastic member 40 and the associated structure of the U.S. Patent No. 7,008,053 ,

If the ink supply system supplies ink to the printing device, if it is held too tight, contact with some of the device side contacting elements (e.g., port 734 in the 31 ) not sure. By disposing the engaging portion of the first restricting portion to the left of a right edge of a rightmost terminal of the plurality of terminals and to the right of a left edge of the leftmost terminal of the plurality of terminals, the ink cartridge may tilt sufficiently so that the electrical connection between the plurality of terminals and the device side contact-forming elements can be even more stable.

Application 3

The ink delivery system as described above, further comprising: a body ( 22 ), which has a front side ( 203 ) and a back ( 204 ), the front side ( 203 ) and the back ( 204 ) are opposite one another, a second restriction section ( 220 ) close to the back ( 204 ) of the body ( 22 ), wherein the connection carrier structure ( 408 ) close to the front ( 203 ) of the body ( 22 ), the second restriction section ( 220 ) is designed and set up with an appropriate section ( 620 ) of the inkjet printing device ( 50 ), and the distance (B) between the engaging portion of the second restricting portion (FIG. 220 ) and the front edge ( 288 ) defined plane (BP) is greater than the distance (A) between the engaging portion ( 212 ) of the first restriction section ( 210 ) and the front edge ( 288 ) defined plane (BP), when the distances in one to the through the leading edge ( 288 ) defined plane (BP) vertical direction.

When the engaging portion of the second restricting portion is located farther from the plane defined by the leading edge than the engaging portion of the first restricting portion, the likelihood that the first restricting portion is disengaged from the printer engaging portion can be further increased as compared with the case where the engaging portion of the first restricting portion from the plane defined by the leading edge than the engaging portion of the second restricting portion can be reduced more effectively.

Application 4

The ink delivery system as described above, further comprising: a body ( 22 ), which has a first surface ( 203 ) and a second surface ( 204 ), wherein the first surface ( 203 ) and the second surface ( 204 ) are opposite one another, a second restriction section ( 220 ) close to the second surface ( 204 ) of the body ( 22 ), wherein the connection carrier structure ( 408 ) Near to the first surface ( 203 ) of the body ( 22 ), the second restriction section ( 220 ) is designed and set up with an appropriate section ( 620 ) of the inkjet printing device ( 50 ), and the distance (B) between the engaging portion of the second restricting portion (FIG. 220 ) and the front edge ( 288 ) defined plane (BP) is greater than the distance (A) between the engaging portion ( 212 ) of the first restriction section ( 210 ) and the front edge ( 288 ) defined plane (BP), when the distances in one to the through the leading edge ( 288 ) defined plane (BP) vertical direction.

When the engaging portion of the second restricting portion is located farther from the plane defined by the leading edge than the engaging portion of the first restricting portion, the likelihood that the first restricting portion is disengaged from the printer engaging portion can be further increased as compared with the case where the engaging portion of the first restricting portion from the plane defined by the leading edge than the engaging portion of the second restricting portion can be reduced more effectively.

Application 5

The ink supply system as described above, wherein the distance (A) between the engaging portion (FIG. 212 ) of the first restriction section ( 210 ) and the front edge ( 288 ) defined plane (BP) is smaller than the distance (C) between a pivot ( 800c ) of the lever ( 80 ) and the front edge ( 288 ) defined plane (BP), when the ink supply system Tine to the printing device ( 50 ), when the distances in one to the through the leading edge ( 288 ) defined plane (BP) vertical direction.

When the distance between the engaging portion of the first restricting portion and the plane defined by the leading edge is smaller than the distance between a pivot point of the lever and the plane defined by the leading edge when the ink supply system supplies ink to the printing apparatus, the lever serves to move restrict. This reduces the likelihood that the first restricting portion will be released or disengaged from the engaging portion of the lever, thereby creating a stable electrical connection between the plurality of terminals and the contact forming elements and reducing the likelihood of poor continuity. The first restriction portion may move about the rotation axis of the lever when a force is applied from the contact formation members. This reduces the likelihood that the engaging portion of the first restricting portion is decoupled from the engaging portion of the lever.

When the ink supply system supplies ink to the printing apparatus, and the engaging portion of the first restricting portion is located to the left of a fulcrum of the lever and the engaging portion of the first restricting portion is right and the ink supply structure is downward, the first restricting portion generates a torque on the lever about the lever to rotate the axis of rotation of the lever in the direction opposite to the direction of release. This reduces the likelihood that the engaging portion of the first restricting portion will be released from the engaging portion of the lever, and further ensures the stable electrical connection between the plural terminals and the apparatus-side contact forming members. Further, the likelihood that the engaging portion of the first restricting portion is released from the engaging portion of the lever is reduced.

Some of the advantages of the above modification of the seventh modification will now be described. The ports must be accurately located and stably fixed while the ink cartridge is inserted into the printer to ensure reliable electrical communication between the cartridge and the printer. Since the engaging portion of the first restricting portion is located adjacent to the terminal support structure, a positioning action of the first restricting portion comes close to the position where positioning is most needed (that is, at the terminals of the terminal support structure). The elastic force from the device side terminals can be appropriately counteracted. In addition, a positional shift of the terminals, which may occur due to vibration during printing operations, can be suppressed. Therefore, the arrangement of the terminals is more stable, whereby the stable electrical connection between the cartridge-side terminals and the device-side terminals is maintained.

In addition, since the lever is not integrally formed with the cartridge, the material for producing the cartridge may be different from the material used to manufacture the lever. In addition, the material of the cartridge with less regard to flexibility and durability requirements and with a greater attention to other properties, such as resistance to ink, are selected.

In addition, since the lever is not disposed on the cartridge, no special care is required to prevent creep of the lever during packing of the cartridge for transportation and distribution. This simplifies the packaging requirements and improves the user-friendliness. Since the lever is not an integral part of the cartridge, the cartridge can be made smaller.

Since the printer terminals exert an elastic force on the cartridge terminals, which includes a vector component in the direction in which the cartridge is detached from the printer, there is no need to use a spring like the one in FIG U.S. Patent 6,955,422 described spring 103 provided. In other words, the elastic force from the printer-side terminals serves to press both the printer-side and cartridge-side terminals against each other and to move the cartridge in the direction for detaching from the printer when the engagement between the first restricting portion and the printer lever is released. Therefore, there is no need to provide an additional spring as in the case of US Pat. No. 6,955,422, thereby allowing a simpler structure and reduced costs.

As a result, since the first restricting portion is engaged with the engagement portion of the lever so as to restrict the movement of the cartridge in the direction opposite to the attachment direction, the position of the cartridge ports with respect to the attachment direction is determined by the elastic force of the device side contact forming elements and with respect to the direction opposite to the mounting direction by the first restricting portion maintained when the cartridge is inserted into the printer. Since the cartridge terminals are "embedded" in this manner, they are firmly fixed against movement both in the mounting direction and in the direction opposite to the mounting direction. Therefore, there is less likelihood of misalignment or separation between the cartridge terminals and the device side contact-forming members as compared with the one-sided restriction by the elastic member 40 and the associated structure of the U.S. Patent No. 7,008,053 ,

Application 1

The ink delivery system as described above, wherein the connection plane (TP) is at an angle of between approximately 25 and 40 degrees to that through the leading edge (16). 288 ) defined plane (BP) is when the ink supply system ink to the printing device ( 50 ) feeds.

How about the 42A - 45 is discussed, if the terminal plane is at an angle between approximately 25 and 40 degrees relative to the plane defined by the leading edge, excessive wiping is prevented and sufficient force for preventing half insertion can be exerted.

Application 2

The ink supply system as described above, wherein when the ink supply system supplies ink to the printing apparatus ( 50 ), the engaging section ( 212 ) of the first restriction section ( 210 ) to the left of a right edge of a rightmost terminal of the plurality of terminals ( 400 ) and to the right of a left edge of the leftmost terminal of the plurality of terminals ( 400 ) is arranged.

If the ink supply system supplies ink to the printing device, if it is held too tight, contact with some of the device side contacting elements (e.g., port 734 in the 31 ) not sure. By disposing the engaging portion of the first restricting portion to the left of a right edge of a rightmost terminal of the plurality of terminals and to the right of a left edge of the leftmost terminal of the plurality of terminals, the ink cartridge may tilt sufficiently so that the electrical connection between the plurality of terminals and the device side contact-forming elements can be even more stable.

Application 3

The ink delivery system as described above, further comprising: a body ( 22 ), which has a front side ( 203 ) and a back ( 204 ), the front side ( 203 ) and the back ( 204 ) are opposite one another, a second restriction section ( 220 ) close to the back ( 204 ) of the body ( 22 ), wherein the connection carrier structure ( 408 ) close to the front ( 203 ) of the body ( 22 ), the second restriction section ( 220 ) with a corresponding section ( 620 ) of the inkjet printing device ( 50 ) and the distance (B) between the engaging portion of the second restricting portion (FIG. 220 ) and the front edge ( 288 ) defined plane (BP) is greater than the distance (A) between the engaging portion ( 212 ) of the first restriction section ( 210 ) and the front edge ( 288 ) defined plane (BP), when the distances in one to the through the leading edge ( 288 ) defined plane (BP) vertical direction.

When the engaging portion of the second restricting portion is located farther from the plane defined by the leading edge than the engaging portion of the first restricting portion, the likelihood that the first restricting portion is disengaged from the printer engaging portion can be further increased as compared with the case where the engaging portion of the first restricting portion from the plane defined by the leading edge than the engaging portion of the second restricting portion can be reduced more effectively.

Application 4

The ink delivery system as described above, further comprising: a body ( 22 ), which has a first surface ( 203 ) and a second surface ( 204 ), wherein the first surface ( 203 ) and the second surface ( 204 ) are opposite one another, a second restriction section ( 220 ) close to the second surface ( 204 ) of the body ( 22 ), wherein the connection carrier structure ( 408 ) close to the first surface ( 203 ) of the body ( 22 ), the second restriction section ( 220 ) with a corresponding section ( 620 ) of the inkjet printing device ( 50 ) and the distance (B) between the engaging portion of the second restricting portion (FIG. 220 ) and the front edge ( 288 ) defined plane (BP) is greater than the distance (A) between the engaging portion ( 212 ) of the first restriction section ( 210 ) and the front edge ( 288 ) defined plane (BP), when the distances in one to the through the leading edge ( 288 ) defined plane (BP) vertical direction.

When the engaging portion of the second restricting portion is located farther from the plane defined by the leading edge than the engaging portion of the first restricting portion, the likelihood that the first restricting portion is disengaged from the printer engaging portion can be further increased as compared with the case where the engaging portion of the first restricting portion from the plane defined by the leading edge than the engaging portion of the second restricting portion can be reduced more effectively.

Application 5

The ink supply system described above, wherein the lever ( 80 ) two ends and a pivot point ( 800c ) between the two ends and the distance (A) between the engaging portion ( 212 ) of the first restriction section ( 210 ) and the front edge ( 288 ) defined plane (BP) is smaller than the distance (C) between the pivot ( 800c ) of the lever ( 80 ) and the front edge ( 288 ) defined plane (BP), when the ink supply system Tine to the printing device ( 50 ), when the distances in one to the through the leading edge ( 288 ) defined plane (BP) vertical direction.

When the distance between the engaging portion of the first restricting portion and the plane defined by the leading edge is smaller than the distance between a pivot point of the lever and the plane defined by the leading edge when the ink supply system supplies ink to the printing apparatus, the lever serves to move restrict. This reduces the likelihood that the first restricting portion will be released or disengaged from the engaging portion of the lever, thereby creating a stable electrical connection between the plurality of terminals and the contact forming elements and reducing the likelihood of poor continuity. The first restriction portion may move about the rotation axis of the lever when a force is applied from the contact formation members. This reduces the likelihood that the engaging portion of the first restricting portion is decoupled from the engaging portion of the lever.

Application 6

The ink supply system as described above, wherein the lever ( 80 ) two ends and a pivot point ( 800c ) between the two ends and, when the ink supply system of the printing device ( 50 ) Supplies ink, the engaging section ( 212 ) of the first restriction section ( 210 ) lies to the right and the ink feed structure ( 280 ) downwards, the engaging portion ( 212 ) of the first restriction section ( 210 ) to the left of the pivot ( 800c ) of the lever is arranged.

When the ink supply system supplies ink to the printing apparatus, and the engaging portion of the first restricting portion is located to the left of a fulcrum of the lever and the engaging portion of the first restricting portion is right and the ink supply structure is downward, the first restricting portion generates a torque on the lever about the lever to rotate the axis of rotation of the lever in the direction opposite to the direction of release. This reduces the likelihood that the engaging portion of the first restricting portion will be released from the engaging portion of the lever, and further ensures the stable electrical connection between the plural terminals and the apparatus-side contact forming members. Further, the likelihood that the engaging portion of the first restricting portion becomes from the Engagement portion of the lever is released, reduced.

Application 7

By providing the first restricting portion in such a position that at least a portion of the engaging portion of the first restricting portion is located substantially at the center of the body in the width direction, the first restricting portion is disposed extremely close to the plurality of terminals so that the electrical connection between the plurality of terminals and the device-side contact forming elements can be stable.

Application 8

Application 9

G-eighth Eighth Modification

The invention may be practiced by the following descriptions and changes. The characters in parentheses after the elements in each of the descriptions correspond to the characters of the respective elements described in the first embodiment or in the modification of the cartridge with the adapter.

G-8-1. First change

A cartridge ( 20 ) which is adapted to be attached to a printing device, comprising the following structures: 50 ) comprises a plurality of device-side contact-forming elements ( 731 - 739 ), which are designed to apply an elastic force (Pt) to the cartridge ( 20 ), the printing device ( 50 ) also includes a lever ( 80 ) with an engaging portion ( 810 ) and the cartridge ( 20 ) comprises: a first surface ( 203 ), a second surface ( 204 ), a third surface ( 202 ) and a fourth surface ( 201 ), the first surface ( 203 ) and the second surface ( 204 ) face each other and the third surface ( 202 ) and the fourth surface ( 201 ) face each other; an electrical device; a fluid chamber ( 200 ) for storing liquid; a liquid supply structure ( 280 ) on the fourth surface ( 201 ) and is arranged to remove a liquid from the liquid chamber ( 200 ) to the printing device ( 50 ), the liquid feed structure ( 280 ) an attachment direction (SD) leading edge ( 288 ) having a plane (BP) of the cartridge ( 20 ) Are defined; electrically conductive connections ( 400 ) closer to the first surface ( 203 ) than to the second surface ( 204 ) are arranged and coupled to the electrical device, wherein the terminals ( 400 ) are adapted to contact portions (cp) of the terminals (c) 400 ) with the contact-forming elements ( 731 - 739 ) and to receive the elastic force (Pt) from them when the cartridge ( 20 ) on the printing device ( 50 ), wherein the contact portions (cp) of the terminals (c) 400 ) are arranged substantially in a contact section plane (TP) which is neither parallel nor perpendicular to that through the leading edge (TP). 288 ) defined level (BP); and a first restriction section ( 210 ), which is designed with the engagement section ( 810 ) of Levers ( 80 ) to engage a movement of the cartridge ( 20 ) in a direction opposite to the attachment direction (SD) direction (RD), wherein the engaging portion (R) ( 212 ) of the first restriction section ( 210 ) at a position closer to the contact portions (cp) than to a cutting area (cp) 291 ) of the third surface ( 202 ) and the first surface ( 203 ) is arranged.

Some of the advantages of the above modification of the eighth modification will now be described. The terminals must be accurately located and stably fixed while the cartridge is inserted into the printing device to ensure reliable electrical communication between the cartridge and the printing device. Since the engagement portion of the first restriction portion is located at a position nearer to the contact portions than to a sectional area of the third surface and the first surface, a positioning effect of the first restriction portion comes close to the position where positioning is most needed (ie at the terminals of the terminal support structure). The elastic force from the device side terminals can be appropriately counteracted. In addition, a positional shift of the terminals, which may occur due to vibration during printing operations, can be suppressed. Therefore, the arrangement of the terminals is more stable, whereby the stable electrical connection between the cartridge-side terminals and the device-side terminals is maintained.

In addition, since the lever is not integrally formed with the cartridge, the material for producing the cartridge may be different from the material used to manufacture the lever. In addition, the material of the cartridge may be selected with less regard to flexibility and durability requirements and with a greater attention to other properties, such as resistance to fluid.

In addition, since the lever is not disposed on the cartridge, no special care is required to prevent creep of the lever during packing of the cartridge for transportation and distribution. This simplifies the packaging requirements and improves the user-friendliness. Since the lever is not an integral part of the cartridge, the cartridge can be made smaller. This further enables size reduction of the packaging material, such as a paper or box, used to package the cartridge for transport or distribution of the cartridge, thereby advantageously reducing transport and component costs. In addition, since the lever is not formed integrally with the cartridge, the first cartridge-side restricting portion with a small size and simple structure and, for example, compared with those in US Publication No. 2005/0151811 described structures, higher rigidity are formed. As a result, the likelihood of plastic deformation of the first cartridge-side restricting portion is significantly reduced. In the attached or inserted state, the cartridge can be held in the proper position in the cartridge attachment structure, thereby maintaining normal or good contact between the cartridge side ports and the device side ports and reducing the likelihood of poor electrical communication. Since the first cartridge-side restricting portion may have a small size and a simple structure, unlike the cartridges of US Publication No. 2005/0151811, no special care is required in the package for transporting and distributing the cartridge to creep deformation of the lever to prevent. This reduces the packaging requirements and also improves the user-friendliness.

It is possible that the structure connecting the cartridge terminals and the engaging portion of the cartridge is only a rigid structure (which is for the flexible levers of the US Publication No. 2005/0151811 not the case). In this case, less vibration is transmitted from the engaging portion to the cartridge terminals, so that the electrical communication is more stable.

Since the contact section plane (TP) of the terminals is neither parallel nor perpendicular to that through the leading edge (FIG. 288 ) defined plane (BP), the surface of the cartridge ports can be properly wiped during insertion of the cartridge into the printing device. In addition, this design reduces or eliminates isolation debris (dust) that can be generated when the device-side ports rub against the board over long distances during the attachment of the cartridge.

Since the jig-side terminals exert an elastic force on the cartridge terminals, which includes a vector component in the direction in which the cartridge is detached from the printing apparatus, there is no need to use a spring like the one in FIG U.S. Patent 6,955,422 described spring 103 provided. In other words, the elastic force from the device-side terminals serves to press both the device-side and cartridge-side terminals against each other as well as to move the cartridge in the direction to remove from the printing device when the engagement between the first restriction portion and the lever is released. Therefore There is no need to provide an additional spring, as in the case of US Pat. No. 6,955,422, which allows a simpler structure and reduced costs.

As a result, since the first restricting portion is adapted to engage with the engaging portion of the lever so as to restrict the movement of the cartridge in the direction opposite to the mounting direction, the position of the cartridge terminals with respect to the mounting direction by the elastic Maintain force of the device-side contact-forming elements and with respect to the direction opposite to the mounting direction by the first restricting portion when the cartridge is inserted into the printing device. Since the cartridge terminals are "embedded" in this manner, they are firmly fixed against movement both in the mounting direction and in the direction opposite to the mounting direction. Therefore, there is less likelihood of misalignment or separation between the cartridge terminals and the device side contact-forming members as compared with the one-sided restriction by the elastic member 40 and the associated structure of the U.S. Patent No. 7,008,053 ,

Application 1:

The cartridge as described above ( 20 ), in which the engaging portion ( 212 ) of the first restriction section ( 210 ) at a position closer to the contact portions (cp) than to the center ( 203P ) between a cutting area ( 295 ) of the first surface ( 203 ) and the contact portion plane (TP) and a cutting region ( 291 ) of the third surface ( 202 ) and the first surface ( 203 ) is arranged.

By arranging the engaging portion of the first restricting portion at a position closer to the contact portions than to the center, the above-described advantages can be favorably obtained.

Application 2:

The cartridge as described above ( 20 ), wherein the contact portion plane (TP) is at an angle of between 25 and 40 degrees to that through the leading edge (TP). 288 ) defined level (BP).

How about the 42A - 45 is discussed, if the contact portion plane is at an angle between approximately 25 and 40 degrees relative to the plane defined by the leading edge, excessive wiping is prevented and sufficient force for preventing half insertion can be exerted.

Application 3:

The cartridge as described above ( 20 ), when, when the first surface ( 203 ) of the cartridge ( 20 ) is considered to be such that the liquid feed structure ( 280 ) downwards, the engaging portion ( 212 ) of the first restriction section ( 210 ) to the left of an extended line ( 439PL ) of a right edge ( 439P ) of a rightmost terminal ( 439 ) of the multiple connections ( 431 - 439 ) and to the right of an extended line ( 435PL ) of a left edge ( 435P ) of a leftmost terminal ( 435 ) of the multiple connections ( 431 - 439 ) is arranged.

If the cartridge is attached to the printing device, if the cartridge is held too tight, contact with some of the device-side contact forming elements (e.g., port 734 in the 31 ) not sure. By disposing the engagement portion of the first restricting portion to the left of the rightmost contact portion of the plurality of terminals and to the right of the leftmost contact portion of the plurality of terminals, the cartridge may tilt sufficiently so that the electrical connection between the plurality of terminals and the device side contact forming elements is even more stable can be.

Application 4:

The cartridge as described above ( 20 ), which further comprises a second restriction section ( 220 ) on the second surface ( 204 ) of the cartridge ( 20 ), the second restriction section ( 220 ) is designed with a corresponding section of the printing device ( 50 ) and the distance (B) between the engaging portion (FIG. 222 ) of the second restriction section ( 220 ) and the front edge ( 288 ) defined plane (BP) is greater than the distance (A) between the engaging portion ( 212 ) of the first restriction section ( 210 ) and the front edge ( 288 ) defined plane (BP), when the distances in one to the through the leading edge ( 288 ) defined plane (BP) vertical direction.

When the engaging portion of the second Restriction portion is disposed farther away from the plane defined by the leading edge than the engagement portion of the first restriction portion, the probability that the first restriction portion of the device-side engagement portion is released compared to the case that the engagement portion of the first restriction portion further from that through the Front edge defined plane is arranged as the engagement portion of the second restriction portion, can be reduced more effectively.

Application 5:

The cartridge as described above ( 20 ), when, when the cartridge ( 20 ) is viewed from the angle at which the engagement portion ( 212 ) of the first restriction section ( 210 ) lies to the right and the liquid feed structure ( 280 ) downwards, the distance (A) between the engagement portion ( 212 ) of the first restriction section ( 210 ) and the front edge ( 288 ) defined plane (BP) is smaller than the distance (C) between a pivot ( 800c ) of the lever ( 80 ) and the front edge ( 288 ) defined level (BP) when the cartridge ( 20 ) is mounted when the distances in one to the through the leading edge ( 288 ) defined plane (BP) vertical direction.

When the distance between the engaging portion of the first restricting portion and the plane defined by the leading edge is smaller than the distance between a pivot point of the lever and the plane defined by the leading edge when the cartridge is mounted, the lever serves to move the cartridge restrict. This reduces the likelihood that the first restricting portion will be released or disengaged from the engaging portion of the lever, thereby creating a stable electrical connection between the plurality of terminals and the contact forming elements and reducing the likelihood of poor continuity. The first restriction portion may move about the rotation axis of the lever when a force is applied from the contact formation members to the attached cartridge. This reduces the likelihood that the engaging portion of the first restricting portion is decoupled from the engaging portion of the lever.

Application 6:

The cartridge as described above ( 20 ), when, when the cartridge ( 20 ) is viewed from the angle at which the engagement portion ( 212 ) of the first restriction section ( 210 ) lies to the right and the liquid feed structure ( 280 ) downwards, the engaging portion ( 212 ) of the first restriction section ( 210 ) to the left of the pivot ( 800c ) of the lever ( 80 ) is arranged when the cartridge ( 20 ) is attached.

When the cartridge is mounted so that the engaging portion of the first restricting portion is located to the left of a fulcrum of the lever, when the cartridge is viewed from the side so that the engaging portion of the first restricting portion is right and the liquid supplying structure is facing down, the first one generates Restriction section, a torque on the lever to rotate the lever about the axis of rotation of the lever in the direction opposite to the release direction. This reduces the likelihood that the engaging portion of the first restricting portion will be released from the engaging portion of the lever, and further ensures the stable electrical connection between the plural terminals and the apparatus-side contact forming members. Even if the cartridge receives a force, the first restriction portion would move with the cartridge. Such movement reduces the likelihood that the engaging portion of the first restricting portion will be released from the engaging portion of the lever.

Application 7:

The cartridge as described above ( 20 ), when, when the first surface ( 203 ) is considered to be such that the liquid feed structure ( 280 ), at least a portion of the engaging portion (FIG. 212 ) of the first restriction section ( 210 ) substantially at the center of the cartridge ( 20 ) is arranged in the width direction when the cartridge ( 20 ) is attached.

By providing the first restricting portion in such a position that at least a portion of the engaging portion of the first restricting portion is located substantially at the center of the cartridge in the width direction, the first restricting portion is disposed extremely close to the plurality of terminals so that the electrical connection between the plurality of terminals and the device-side contact forming elements can be stable.

Application 8:

The cartridge as described above ( 20 ), in which by the leading edge ( 288 ) defined plane (BP) is substantially flush with the fourth surface ( 201 ).

Application 9:

The cartridge as described above ( 20 ), which has an adapter ( 299 . 299j . 299K ), wherein the contact portions (cp) of the terminals (c) 400 ) and the first restriction section ( 210 ) are arranged on the adapter and the liquid chamber ( 200 ) is designed and arranged to be connected to the adapter.

G-8-2. Second change

A cartridge ( 20 ), which is adapted to a printing device ( 50 ), the printing device ( 50 ) a plurality of device-side contact-forming elements ( 731 - 739 ) designed to apply an elastic force (Pt) to the cartridge ( 20 ), the printing device ( 50 ) also a lever ( 80 ) with an engaging portion ( 810 ) and the cartridge ( 20 ) comprises: a first surface ( 203 ), a second surface ( 204 ), a third surface and a fourth surface ( 201 ), the first surface ( 203 ) and the second surface ( 204 ) face each other and the third surface ( 202 ) and the fourth surface ( 201 ) face each other; an electrical device; a fluid chamber ( 200 ) for storing liquid; a liquid supply structure ( 280 ) on the fourth surface ( 201 ) and is arranged to remove a liquid from the liquid chamber ( 200 ) to the printing device ( 50 ), the liquid feed structure ( 280 ) an attachment direction (SD) leading edge ( 288 ) having a plane (BP) of the cartridge ( 20 ) Are defined; electrically conductive connections ( 400 ) closer to the first surface ( 203 ) than to the second surface ( 204 ) are arranged and coupled to the electrical device, wherein the terminals ( 400 ) are adapted to contact portions (cp) of the terminals (c) 400 ) with the contact-forming elements ( 731 - 739 ) and to receive the elastic force (Pt) from them when the cartridge ( 20 ) on the printing device ( 50 ), wherein the contact portions (cp) of the terminals (c) 400 ) are arranged substantially in a contact section plane (TP) which is neither parallel nor perpendicular to that through the leading edge (TP). 288 ) defined level (BP); and a first restriction section ( 210 ), which is designed with the engagement section ( 810 ) of the lever ( 80 ) to engage a movement of the cartridge ( 20 ) in a direction opposite to the attachment direction (SD) (RD), the first restriction section (R) 210 ) at a position closer to a first cutting area ( 295 ), on which the first surface ( 203 ) intersects the contact portion plane (TP), as to a second intersection region, where the first surface (TP) 203 ) the third surface ( 202 ), is provided.

Some of the advantages of the above modification of the eighth modification will now be described. The terminals must be accurately located and stably fixed while the cartridge is inserted into the printing device to ensure reliable electrical communication between the cartridge and the printing device. Since the engaging portion of the first restricting portion is located at a position closer to a first cutting region where the first surface intersects the contact portion plane than to a second cutting region where the first surface intersects the third surface, a positioning action of the first restricting portion becomes close to the location where positioning is most needed (that is, at the terminals of the terminal support structure).

The cartridge as described above ( 20 ) in which the engaging portion of the first restricting portion is at a position closer to the first cutting portion (FIG. 295 ) than to the midpoint ( 203P ) between the first cutting area ( 295 ) and the second cutting area is arranged.

By arranging the engaging portion of the first restricting portion at a position closer to the contact portions than to the center, the above-described advantages can be favorably obtained.

Application 2

The cartridge as described above ( 20 ), wherein the contact portion plane (TP) is at an angle of between 25 and 40 degrees to that through the leading edge (TP). 288 ) defined level (BP).

How about the 42A - 45 is discussed, if the contact portion plane is at an angle between approximately 25 and 40 degrees relative to the plane defined by the leading edge, excessive wiping is prevented and sufficient force for preventing half insertion can be exerted.

Application 3

The cartridge as described above ( 20 ), when, when the first surface ( 203 ) of the cartridge ( 20 ) is considered to be such that the liquid feed structure ( 280 ) downwards, the engaging portion ( 212 ) of the first restriction section ( 210 ) to the left of an extended line ( 439PL ) of a right edge ( 439P ) of a rightmost terminal ( 439 ) of the multiple connections ( 431 - 439 ) and to the right of an extended line ( 435PL ) of a left edge ( 435P ) of a leftmost terminal ( 435 ) of the multiple connections ( 431 - 439 ) is arranged.

If the cartridge is attached to the printing device, if the cartridge is held too tight, contact with some of the device-side contact forming elements (e.g. connection 734 in the 31 ) not sure. By disposing the engagement portion of the first restricting portion to the left of the rightmost contact portion of the plurality of terminals and to the right of the leftmost contact portion of the plurality of terminals, the cartridge may tilt sufficiently so that the electrical connection between the plurality of terminals and the device side contact forming elements is even more stable can be.

Application 4

The cartridge as described above ( 20 ), which further comprises a second restriction section ( 220 ) on the second surface ( 204 ) of the cartridge ( 20 ), the second restriction section ( 220 ) is designed with a corresponding section of the printing device ( 50 ) and the distance (B) between the engaging portion (FIG. 222 ) of the second restriction section ( 220 ) and the front edge ( 288 ) defined plane (BP) is greater than the distance (A) between the engaging portion ( 212 ) of the first restriction section ( 210 ) and the front edge ( 288 ) defined plane (BP), when the distances in one to the through the leading edge ( 288 ) defined plane (BP) vertical direction.

When the engaging portion of the second restricting portion is located farther from the plane defined by the leading edge than the engaging portion of the first restricting portion, the likelihood that the first restricting portion is disengaged from the apparatus-side engaging portion can be compared with the case where the engaging portion of the first restricting portion farther away from the plane defined by the leading edge than the engaging portion of the second restricting portion is more effectively decreased.

Application 5

The cartridge as described above ( 20 ), when, when the cartridge ( 20 ) is viewed from the angle at which the engagement portion ( 212 ) of the first restriction section ( 210 ) lies to the right and the liquid feed structure ( 280 ) downwards, the distance (A) between the engagement portion ( 212 ) of the first restriction section ( 210 ) and the front edge ( 288 ) defined plane (BP) is smaller than the distance (C) between a pivot ( 800c ) of the lever ( 80 ) and the front edge ( 288 ) defined level (BP) when the cartridge ( 20 ) is mounted when the distances in one to the through the leading edge ( 288 ) defined plane (BP) vertical direction.

When the distance between the engaging portion of the first restricting portion and the plane defined by the leading edge is smaller than the distance between a pivot point of the lever and the plane defined by the leading edge when the cartridge is mounted, the lever serves to move the cartridge restrict. This reduces the likelihood that the first restricting portion will be released or disengaged from the engaging portion of the lever, thereby creating a stable electrical connection between the plurality of terminals and the contact forming elements and reducing the likelihood of poor continuity. The first restriction portion may move about the rotation axis of the lever when a force is applied from the contact formation members to the attached cartridge. This reduces the likelihood that the engaging portion of the first restricting portion is decoupled from the engaging portion of the lever.

Application 6

The cartridge as described above ( 20 ), when, when the cartridge ( 20 ) is viewed from the angle at which the engagement portion ( 212 ) of the first restriction section ( 210 ) lies to the right and the liquid feed structure ( 280 ) downwards, the engaging portion ( 212 ) of the first restriction section ( 210 ) to the left of the pivot ( 800c ) of the lever ( 80 ) is arranged when the cartridge ( 20 ) is attached.

When the cartridge is mounted so that the engaging portion of the first restricting portion is located to the left of a fulcrum of the lever, when the cartridge is viewed from the side so that the engaging portion of the first restricting portion is right and the liquid supplying structure is facing down, the first one generates Restriction section, a torque on the lever to rotate the lever about the axis of rotation of the lever in the direction opposite to the release direction. This reduces the likelihood that the engaging portion of the first restricting portion will be released from the engaging portion of the lever, and further ensures the stable electrical connection between the plural terminals and the apparatus-side contact forming members. Even if the cartridge receives a force, the first restriction portion would move with the cartridge. Such movement reduces the likelihood that the engaging portion of the first restricting portion will be released from the engaging portion of the lever.

Application 7

The cartridge as described above ( 20 ), when, when the first surface ( 203 ) is considered to be such that the liquid feed structure ( 280 ), at least a portion of the engaging portion (FIG. 212 ) of the first restriction section ( 210 ) substantially at the center of the cartridge ( 20 ) is arranged in the width direction when the cartridge ( 20 ) is attached.

By providing the first restricting portion in such a position that at least a portion of the engaging portion of the first restricting portion is located substantially at the center of the cartridge in the width direction, the first restricting portion is disposed extremely close to the plurality of terminals so that the electrical connection between the plurality of terminals and the device-side contact forming elements can be stable.

Application 8

The cartridge as described above ( 20 ), in which by the leading edge ( 288 ) defined plane (BP) is substantially flush with the fourth surface ( 201 ).

Application 9

The cartridge as described above ( 20 ), which has an adapter ( 299 . 299j . 299K ), wherein the contact portions (cp) of the terminals (c) 400 ) and the first restriction section ( 210 ) are arranged on the adapter and the liquid chamber ( 200 ) is designed and arranged to be connected to the adapter.

G-8-3. Third change

A cartridge ( 20 ), which is adapted to a printing device ( 50 ), having the following structures: the printing device ( 50 ) comprises a plurality of device-side contact-forming elements ( 731 - 739 ), which are adapted to apply an elastic force (Pt) to the cartridge ( 20 ), the printing device ( 50 ) also includes a lever ( 80 ) with an engaging portion ( 810 ) and a pivot, and the cartridge ( 20 ) comprises: a first surface ( 203 ), a second surface ( 204 ), a third surface ( 202 ) and a fourth surface ( 201 ), the first surface ( 203 ) and the second surface ( 204 ) face each other and the third surface ( 202 ) and the fourth surface ( 201 ) face each other; an electrical device; a fluid chamber ( 200 ) for storing liquid; a liquid supply structure ( 280 ) on the fourth surface ( 201 ) and is arranged to remove liquid from the liquid chamber ( 200 ) to the printing device ( 50 ), the liquid feed structure ( 280 ) an attachment direction (SD) leading edge ( 288 ) having a plane (BP) of the cartridge ( 20 ) Are defined; electrically conductive connections ( 400 ) closer to the first surface ( 203 ) than to the second surface ( 204 ) and are coupled to the electrical device, wherein the terminals ( 400 ) are adapted to contact portions (cp) of the terminals (c) 400 ) with the contact-forming elements ( 731 - 739 ) and to receive the elastic force (Pt) from them when the cartridge ( 20 ) on the printing device ( 50 ), wherein the contact portions (cp) of the terminals (c) 400 ) are arranged substantially in a contact section plane (TP) which is neither parallel nor perpendicular to that through the leading edge (TP). 288 ) defined level (BP); and a first restriction section ( 210 ), which is designed with the engagement section ( 810 ) of the lever ( 80 ) to engage a movement of the cartridge ( 20 ) in a direction opposite to the attachment direction (SD) direction (RD), wherein the engaging portion (R) ( 212 ) of the first restriction section ( 210 ) is arranged so that when the cartridge ( 20 ) on the printing device ( 50 ), the engaging portion ( 212 ) of the first restriction section ( 210 ) with the lever ( 80 ) at a position below the fulcrum ( 800c ) of the lever ( 80 ) is engaged.

Some of the advantages of the above modification of the eighth modification will now be described. The terminals must be accurately located and stably fixed while the cartridge is inserted into the printing device to ensure reliable electrical communication between the cartridge and the printing device. Since the engaging portion of the first restricting portion is located at a position below the pivot point of the lever, the lever serves to restrict the movement of the cartridge. This reduces the likelihood that the first restricting portion will be released or disengaged from the engaging portion of the lever, thereby creating a stable electrical connection between the plurality of terminals and the contact forming elements and reducing the likelihood of poor continuity. The first restriction portion may move about the rotation axis of the lever when a force is applied from the contact formation members to the attached cartridge. This reduces the likelihood that the engaging portion of the first restricting portion is decoupled from the engaging portion of the lever. Therefore, the arrangement of the terminals is more stable, whereby the stable electrical connection between the cartridge-side terminals and the device-side terminals is maintained.

In addition, since the lever is not integrally formed with the cartridge, the material for producing the cartridge may be different from the material used to manufacture the lever. In addition, the material of the cartridge may be selected with less regard to flexibility and durability requirements and with a greater attention to other properties, such as resistance to fluid.

In addition, since the lever is not disposed on the cartridge, no special care is required to prevent creep of the lever during packing of the cartridge for transportation and distribution. This simplifies the packaging requirements and improves the user-friendliness. Since the lever is not an integral part of the cartridge, the cartridge can be made smaller. This further enables size reduction of the packaging material, such as a paper or box, used to package the cartridge for transport or distribution of the cartridge, thereby advantageously reducing transport and component costs. In addition, since the lever is not formed integrally with the cartridge, the first cartridge-side restricting portion with a small size and simple structure and, for example, compared with those in US Publication No. 2005/0151811 described structures, higher rigidity are formed. As a result, the likelihood of plastic deformation of the first cartridge-side restricting portion is significantly reduced. In the attached or inserted state, the cartridge can be held in the proper position in the cartridge attachment structure, thereby maintaining normal or good contact between the cartridge side ports and the device side ports and reducing the likelihood of poor electrical communication. Since the first cartridge-side restricting portion may have a small size and a simple structure, unlike the cartridges of US Publication No. 2005/0151811, no special care is required in the package for transporting and distributing the cartridge to creep deformation of the lever to prevent. This reduces the packaging requirements and also improves the user-friendliness.

It is possible that the structure connecting the cartridge terminals and the engaging portion of the cartridge is only a rigid structure (which is for the flexible levers of the US Publication No. 2005/0151811 not the case). In this case, less vibration is transmitted from the engaging portion to the cartridge terminals, so that the electrical communication is more stable.

Since the contact section plane (TP) of the terminals is neither parallel nor perpendicular to that through the leading edge (FIG. 288 ) defined plane (BP), the surface of the cartridge ports can be properly wiped during insertion of the cartridge into the printing device. In addition, this design reduces or eliminates isolation debris (dust) that can be generated when the device-side ports rub against the board over long distances during the attachment of the cartridge.

Since the jig-side terminals exert an elastic force on the cartridge terminals, which includes a vector component in the direction in which the cartridge is detached from the printing apparatus, there is no need to use a spring like the one in FIG U.S. Patent 6,955,422 described spring 103 provided. In other words, the elastic force from the device-side terminals serves to press both the device-side and cartridge-side terminals against each other as well as to move the cartridge in the direction to remove from the printing device when the engagement between the first restriction portion and the lever is released. Therefore, there is no need to provide an additional spring as in the case of US Pat. No. 6,955,422, thereby allowing a simpler structure and reduced costs.

As a result, since the first restricting portion is adapted to engage with the engaging portion of the lever so as to restrict the movement of the cartridge in the direction opposite to the mounting direction, the position of the cartridge terminals with respect to the mounting direction by the elastic Maintain force of the device-side contact-forming elements and with respect to the direction opposite to the mounting direction by the first restricting portion when the cartridge is inserted into the printing device. Since the cartridge terminals are "embedded" in this manner, they are firmly fixed against movement both in the mounting direction and in the direction opposite to the mounting direction. Therefore, there is less likelihood of misalignment or separation between the cartridge terminals and the device side contact-forming members as compared with the one-sided restriction by the elastic member 40 and the associated structure of the U.S. Patent No. 7,008,053 ,

Application 1

The cartridge as described above ( 20 ), wherein the contact section plane (TP) at a Angle of between 25 and 40 degrees to that through the leading edge ( 288 ) defined level (BP).

By arranging the engaging portion of the first restricting portion at a position closer to the contact portions than to the center, the above-described advantages can be favorably obtained.

How about the 42A - 45 is discussed, if the contact portion plane is at an angle between approximately 25 and 40 degrees relative to the plane defined by the leading edge, excessive wiping is prevented and sufficient force for preventing half insertion can be exerted.

Application 2

The cartridge as described above ( 20 ), when, when the first surface ( 203 ) of the cartridge ( 20 ) is considered to be such that the liquid feed structure ( 280 ) downwards, the engaging portion ( 212 ) of the first restriction section ( 210 ) to the left of an extended line ( 439PL ) of a right edge ( 439P ) of a rightmost terminal ( 439 ) of the multiple connections ( 431 - 439 ) and to the right of an extended line ( 435PL ) of a left edge ( 435P ) of a leftmost terminal ( 435 ) of the multiple connections ( 431 - 439 ) is arranged.

If the cartridge is attached to the printing device, if the cartridge is held too tight, contact with some of the device-side contact forming elements (e.g., port 734 in the 31 ) not sure. By disposing the engagement portion of the first restricting portion to the left of the rightmost contact portion of the plurality of terminals and to the right of the leftmost contact portion of the plurality of terminals, the cartridge may tilt sufficiently so that the electrical connection between the plurality of terminals and the device side contact forming elements is even more stable can be.

Application 3

The cartridge as described above ( 20 ), which further comprises a second restriction section ( 220 ) on the second surface ( 204 ) of the cartridge ( 20 ), the second restriction section ( 220 ) is designed with a corresponding section of the printing device ( 50 ) and the distance (B) between the engaging portion (FIG. 222 ) of the second restriction section ( 220 ) and the front edge ( 288 ) defined plane (BP) is greater than the distance (A) between the engaging portion ( 212 ) of the first restriction section ( 210 ) and the front edge ( 288 ) defined plane (BP), when the distances in one to the through the leading edge ( 288 ) defined plane (BP) vertical direction.

When the engaging portion of the second restricting portion is located farther from the plane defined by the leading edge than the engaging portion of the first restricting portion, the likelihood that the first restricting portion is disengaged from the apparatus-side engaging portion can be compared with the case where the engaging portion of the first restricting portion farther away from the plane defined by the leading edge than the engaging portion of the second restricting portion is more effectively decreased.

Application 4

The cartridge as described above ( 20 ), when, when the cartridge ( 20 ) is viewed from the angle at which the engagement portion ( 212 ) of the first restriction section ( 210 ) lies to the right and the liquid feed structure ( 280 ) downwards, the engaging portion ( 212 ) of the first restriction section ( 210 ) to the left of the pivot ( 800c ) of the lever ( 80 ) is arranged when the cartridge ( 20 ) is attached.

When the cartridge is mounted so that the engaging portion of the first restricting portion is to the left of a fulcrum of the lever, when the cartridge is viewed from the side so that the engaging portion of the first restricting portion is right and the liquid supplying structure is facing down, the first restricting portion generates a torque on the lever to rotate the lever about the axis of rotation of the lever in the direction opposite to the release direction. This reduces the likelihood that the engaging portion of the first restricting portion will be released from the engaging portion of the lever, and further ensures the stable electrical connection between the plural terminals and the apparatus-side contact forming members. Even if the cartridge receives a force, the first restriction portion would move with the cartridge. Such movement reduces the likelihood that the engaging portion of the first restricting portion will be released from the engaging portion of the lever.

Application 5

By providing the first restricting portion in such a position that at least a portion of the engaging portion of the first restricting portion is located substantially at the center of the cartridge in the width direction, the first restricting portion is disposed extremely close to the plurality of terminals so that the electrical connection between the plurality of terminals and the device-side contact forming elements can be stable.

G-8-4. Fourth change

A cartridge ( 20 ), which is adapted to a printing device ( 50 ), the printing device ( 50 ) a plurality of device-side contact-forming elements ( 731 - 739 ) designed to apply an elastic force (Pt) to the cartridge ( 20 ), the printing device ( 50 ) also a lever ( 80 ) with an engaging portion ( 810 ) and the cartridge ( 20 ) comprises: a front side ( 203 ), a back ( 204 ), an upper end ( 202 ) and a lower end ( 201 ), the front side ( 203 ) and the back ( 204 ) are opposite each other and the upper end ( 202 ) and the lower end ( 201 ) face each other; an electrical device; a fluid chamber ( 200 ) for storing liquid; a liquid supply structure ( 280 ) at the lower end ( 201 ) and is arranged to remove liquid from the liquid chamber ( 200 ) to the printing device ( 50 ), the liquid feed structure ( 280 ) an attachment direction (SD) leading edge ( 288 ) having a plane (BP) of the cartridge ( 20 ) Are defined; electrically conductive connections ( 400 ), which are closer to the front ( 203 ) than to the back ( 204 ) are arranged and coupled to the electrical device, wherein the terminals ( 400 ) are adapted to contact portions (cp) of the terminals (c) 400 ) with the contact-forming elements ( 731 - 739 ) and to receive the elastic force (Pt) from them when the cartridge ( 20 ) on the printing device ( 50 ), and the contact portions (cp) of the terminals (c) 400 ) are arranged substantially in a contact section plane (TP) which is neither parallel nor perpendicular to that through the leading edge (TP). 288 ) defined level (BP); and a first restriction section ( 210 ), which is designed with the engaging portion ( 810 ) of the lever ( 80 ) to engage a movement of the cartridge ( 20 ) in a direction opposite to the attachment direction (SD) (RD), the first restriction section (R) 210 ) is provided at a position closer to the contact portion plane (TP) than to the upper end (FIG. 202 ) is arranged.

Some of the advantages of the above modification of the eighth modification will now be described. The terminals must be accurately located and stably fixed while the cartridge is inserted into the printing device to ensure reliable electrical communication between the cartridge and the printing device. Since the engaging portion of the first restricting portion is located at a position closer to the contact portion plane than the upper end, a positioning action of the first restricting portion comes close to the position where positioning is most needed (that is, at the terminals of the terminal support structure). , The elastic force from the device side terminals can be appropriately counteracted. In addition, a positional shift of the terminals, which may occur due to vibration during printing operations, can be suppressed. Therefore, the arrangement of the terminals is more stable, whereby the stable electrical connection between the cartridge-side terminals and the device-side terminals is maintained.

In addition, since the lever is not integrally formed with the cartridge, the material for producing the cartridge may be different from the material used to manufacture the lever. In addition, the material of the cartridge may be selected with less regard to flexibility and durability requirements and with a greater attention to other properties, such as resistance to fluid.

Therefore, there is less likelihood of misalignment or separation between the cartridge terminals and the device side contact-forming members as compared with the one-sided restriction by the elastic member 40 and the associated structure of the U.S. Patent No. 7,008,053 ,

Application 1

Application 3

The cartridge as described above ( 20 ), when, when the front ( 203 ) of the cartridge ( 20 ) is considered to be such that the liquid feed structure ( 280 ) downwards, the engaging portion ( 212 ) of the first restriction section ( 210 ) to the left of an extended line ( 439PL ) of a right edge ( 439P ) of a rightmost terminal ( 439 ) of the multiple connections ( 431 - 439 ) and to the right of an extended line ( 435PL ) of a left edge ( 435P ) of a leftmost terminal ( 435 ) of the multiple connections ( 431 - 439 ) is arranged.

If the cartridge is attached to the printing device, if the cartridge is held too tight, contact with some of the device-side contact forming elements (e.g., port 734 in the 31 ) not sure. By disposing the engagement portion of the first restricting portion to the left of the rightmost contact portion of the plurality of terminals and to the right of the leftmost contact portion of the plurality of terminals, the cartridge may tilt sufficiently so that the electrical connection between the plurality of terminals and the device side contact forming elements is even more stable can be.

Application 4

When the rotatable lever has the fulcrum above the engaging portion of the first restricting portion, the lever serves to restrict the movement of the cartridge. This reduces the likelihood that the first restricting portion will be released or disengaged from the engaging portion of the lever, thereby creating a stable electrical connection between the plurality of terminals and the contact forming elements and reducing the likelihood of poor continuity. The first restriction portion may move about the rotation axis of the lever when a force is applied from the contact formation members to the attached cartridge. This reduces the likelihood that the engaging portion of the first restricting portion is decoupled from the engaging portion of the lever.

Application 5

The cartridge as described above ( 20 ), which further comprises a second restriction section ( 220 ) on the back ( 204 ) of the cartridge ( 20 ), the second restriction section ( 220 ) is designed with a corresponding section of the printing device ( 50 ) and the distance (B) between the engaging portion (FIG. 222 ) of the second restriction section ( 220 ) and the front edge ( 288 ) defined plane (BP) is greater than the distance (A) between the engaging portion ( 212 ) of the first restriction section ( 210 ) and the front edge ( 288 ) defined plane (BP), when the distances in one to the through the leading edge ( 288 ) defined plane (BP) vertical direction.

When the engaging portion of the second restricting portion is located farther from the plane defined by the leading edge than the engaging portion of the first restricting portion, the likelihood that the first restricting portion is disengaged from the apparatus-side engaging portion compared with the case where the engaging portion of the first restricting portion farther away from the plane defined by the leading edge than the engaging portion of the second restricting portion is more effectively decreased.

Application 6

The cartridge as described above ( 20 ), when, when the cartridge ( 20 ) is considered by the angle at which the Engaging section ( 212 ) of the first restriction section ( 210 ) lies to the right and the liquid feed structure ( 280 ) downwards, the distance (A) between the engagement portion ( 212 ) of the first restriction section ( 210 ) and the front edge ( 288 ) defined plane (BP) is smaller than the distance (C) between a pivot ( 800c ) of the lever ( 80 ) and the front edge ( 288 ) defined level (BP) when the cartridge ( 20 ) is mounted when the distances in one to the through the leading edge ( 288 ) defined plane (BP) vertical direction.

When the distance between the engaging portion of the first restricting portion and the plane defined by the leading edge is smaller than the distance between a pivot point of the lever and the plane defined by the leading edge when the cartridge is mounted, the lever serves to move the cartridge restrict. This reduces the likelihood that the first restricting portion will be released or disengaged from the engaging portion of the lever, thereby creating a stable electrical connection between the plurality of terminals and the contact forming elements and reducing the likelihood of poor continuity. The first restriction portion may move about the rotation axis of the lever when a force is applied from the contact formation members to the attached cartridge. This reduces the likelihood that the engaging portion of the first restricting portion is decoupled from the engaging portion of the lever.

The cartridge as described above ( 20 ), when, when the cartridge ( 20 ) is viewed from the angle at which the engagement portion ( 212 ) of the first restriction section ( 210 ) lies to the right and the liquid feed structure ( 280 ) downwards, the engaging portion ( 212 ) of the first restriction section ( 210 ) to the left of the pivot ( 800c ) of the lever ( 80 ) is arranged when the cartridge ( 20 ) is attached.

When the cartridge is mounted so that the engaging portion of the first restricting portion is to the left of a fulcrum of the lever, when the cartridge is viewed from the side so that the engaging portion of the first restricting portion is right and the liquid supplying structure is facing down, the first restricting portion generates a torque on the lever to rotate the lever about the axis of rotation of the lever in the direction opposite to the release direction. This reduces the likelihood that the engaging portion of the first restricting portion will be released from the engaging portion of the lever, and further ensures the stable electrical connection between the plural terminals and the apparatus-side contact forming members. Even if the cartridge receives a force, the first restriction portion would move with the cartridge. Such movement reduces the likelihood that the engaging portion of the first restricting portion will be released from the engaging portion of the lever.

Application 9

The cartridge as described above ( 20 ), when, when the front ( 203 ) is considered to be such that the liquid feed structure ( 280 ), at least a portion of the engaging portion (FIG. 212 ) of the first restriction section ( 210 ) substantially at the center of the cartridge ( 20 ) is arranged in the width direction when the cartridge ( 20 ) is attached.

By providing the first restricting portion in such a position that at least a portion of the engaging portion of the first restricting portion is located substantially at the center of the cartridge in the width direction, the first restricting portion is disposed extremely close to the plurality of terminals so that the electrical connection between the plurality of terminals and the device-side contact forming elements can be stable.

Application 10

The cartridge as described above ( 20 ), in which by the leading edge ( 288 ) defined plane (BP) is substantially flush with the lower end ( 201 ).

Application 11

The cartridge as described above ( 20 ), which has an adapter ( 299 . 299j . 299K ), wherein the contact portions (cp) of the terminals (c) 400 ) and the first restriction section ( 210 ) are arranged on the adapter and the liquid chamber ( 200 ) is designed and arranged to be connected to the adapter.

Application 12

Using the cartridge as described above ( 20 ), in which the engaging portion of the cartridge ( 20 ) with a movable lever ( 80 ) a printing device ( 50 ) is engaged in such a way that the lever ( 80 ) has a pivot point above the engagement portion.

Application 13

The combination of a cartridge ( 20 ) and a printing device ( 50 ), where the Combination comprises: a cartridge as described above ( 20 ); and a printing device ( 50 ), which includes: a plurality of device-side contact-forming elements ( 731 - 739 ), which has an elastic force (Pt) on the cartridge ( 20 ) and a lever ( 80 ), which has an engagement section ( 810 ) adapted to engage with the engaging portion (10). 212 ) of the first restriction section ( 210 ) of the cartridge ( 20 ) to engage a movement of the cartridge ( 20 ) in a direction opposite to the attachment direction (SD) (RD).

Application 14

The combination as described above, in which the lever ( 80 ) has two ends and a pivot point between the two ends and the pivot point ( 800c ) of the lever ( 80 ) above the engaging portion ( 212 ) of the first restriction section ( 210 ) of the cartridge ( 20 ) is provided.

When the rotatable lever has the fulcrum above the engaging portion of the first restricting portion, the lever serves to restrict the movement of the cartridge. This reduces the likelihood that the first restricting portion will be released or disengaged from the engaging portion of the lever, thereby creating a stable electrical connection between the plurality of terminals and the contact forming elements and reducing the likelihood of poor continuity. The first restriction portion may move about the rotation axis of the lever when a force is applied from the contact formation members to the attached cartridge. This reduces the likelihood that the engaging portion of the first restricting portion is decoupled from the engaging portion of the lever.

Application 15

The combination as described above, in which the fulcrum ( 800c ) of the lever ( 80 ) to the right of the engagement section ( 212 ) of the first restriction section ( 210 ) of the cartridge ( 20 ) is provided.

When the fulcrum of the lever is provided to the right of the engaging portion of the first restricting portion of the cartridge, the first restricting portion generates a torque on the lever to rotate the lever about the rotational axis of the lever in the direction opposite to the releasing direction. This reduces the likelihood that the engaging portion of the first restricting portion will be released from the engaging portion of the lever, and further ensures the stable electrical connection between the plural terminals and the apparatus-side contact forming members. Even if the cartridge receives a force, the first restriction portion would move with the cartridge. Such movement reduces the likelihood that the engaging portion of the first restricting portion will be released from the engaging portion of the lever.

G-8-5. Fifth change

A liquid delivery system ( 20i . 20j . 20k ), which is adapted to a printing device ( 50 ) Supply liquid, the printing device ( 50 ) a plurality of device-side contact-forming elements ( 731 - 739 ) and the liquid feed system ( 20i . 20j . 20k ) comprises: an electrical device; a fluid source ( 200i . 200j . 200T ); a liquid supply structure ( 280 ) designed and arranged to deliver liquid from the liquid source ( 200i . 200j . 200T ) to the printing device ( 50 ), the liquid feed structure ( 280 ) an attachment direction (SD) leading edge ( 288 ) defining a plane (BP); an adapter ( 299 . 299j . 299K ) comprising: electrically conductive terminals coupled to the electrical device ( 400 ), the connections ( 400 ) are adapted to contact portions (cp) of the terminals (c) 400 ) with the contact-forming elements ( 731 - 739 ) and to receive an elastic force (Pt) from them when the feeding system ( 20i . 20j . 20k ) of the printing device ( 50 ) Supplies liquid, and the contact portions (cp) of the terminals ( 400 ) are arranged substantially in a contact section plane (TP) which is neither parallel nor perpendicular to that through the front edge (TP). 288 ) defined level lies; and a first restriction section ( 210 ), which is on a front side ( 203 ) of the adapter and is designed to engage with the engaging portion ( 810 ) of the lever ( 80 ), so as to restrict movement of the adapter in a direction opposite to the attachment direction (SD) (RD), the first restriction section (R) 210 ) is disposed adjacent to the contact portion plane (TP).

Some of the advantages of the above modification of the ninth modification will now be described. The terminals must be accurately located and stably fixed while the adapter is inserted into the printing device to ensure reliable electrical communication between the adapter and the printing device. Since the engaging portion of the first restricting portion is disposed adjacent to the contact portion plane, a positioning action of the first restricting portion comes close to the position where positioning is most needed (that is, at the terminals of the terminal support structure). The elastic force from the device side Connections can be counteracted suitably. In addition, a positional shift of the terminals, which may occur due to vibration during printing operations, can be suppressed. Therefore, the arrangement of the terminals is more stable, whereby the stable electrical connection between the adapter-side terminals and the device-side terminals is maintained.

In addition, since the lever is not integrally formed with the adapter, the material for making the adapter may be different from the material used to manufacture the lever. In addition, the material of the adapter may be selected with less regard to flexibility and durability requirements and with a greater attention to other properties, such as resistance to liquid.

In addition, since the lever is not disposed on the adapter, no special care is required to prevent creep deformation of the lever during packaging of the adapter for transportation and distribution. This simplifies the packaging requirements and improves the user-friendliness. Since the lever is not an integral part of the adapter, the adapter can be made smaller. This further enables a size reduction of the packaging material, such as a paper or a box, which is used for packaging the adapter for the transport or distribution of the adapter, whereby the transport and part costs are advantageously reduced. In addition, since the lever is not formed integrally with the adapter, the first adapter-side restricting element with a small size and simple structure and, for example, compared with those in the US Publication No. 2005/0151811 described structures, higher rigidity are formed. As a result, the likelihood of plastic deformation of the first adapter-side restricting element is significantly reduced. In the attached or inserted condition, the adapter may be held in the proper position in the adapter attachment structure, thereby maintaining normal or good contact between the adapter side terminals and the device side terminals and reducing the likelihood of poor electrical communication. Since the first adapter-side restricting member may have a small size and a simple structure, unlike the cartridges of US Publication No. 2005/0151811, no special care is required in the packaging for transport and distribution of the adapter to creep deformation of the lever to prevent. This reduces the packaging requirements and also improves the user-friendliness.

It is possible that the structure connecting the adapter terminals and the engaging portion of the adapter with each other is only a rigid structure (which is for the flexible lever of the US Publication No. 2005/0151811 not the case). In this case, less vibration is transmitted from the engagement portion to the adapter terminals, so that the electrical communication is more stable.

Since the contact section plane (TP) of the terminals is neither parallel nor perpendicular to that through the leading edge (FIG. 288 ) defined plane (BP), the surface of the adapter terminals during insertion of the adapter into the printing device can be wiped properly. In addition, this design reduces or eliminates insulation debris (dust) that can be generated when the device side terminals rub against the board over long distances during the mounting of the adapter.

Since the jig-side terminals exert a resilient force on the adapter terminals, which includes a vector component in the direction in which the adapter is detached from the printing apparatus, there is no need to use a spring like the one in FIG U.S. Patent 6,955,422 described spring 103 provided. In other words, the elastic force from the device side terminals serves to press both the device side and adapter side terminals against each other and to move the adapter in the direction for detaching from the printing device when the engagement between the first restriction section and the lever is released. Therefore exists. there is no need to provide an additional spring, as in the case of US Pat. No. 6,955,422, which allows a simpler structure and reduced costs.

As a result, since the first restricting portion is adapted to engage with the engaging portion of the lever so as to restrict the movement of the adapter in the direction opposite to the mounting direction, the position of the adapter terminals with respect to the mounting direction by the elastic Maintaining force of the device side contact-forming elements and with respect to the direction opposite to the mounting direction by the first restricting portion, when the adapter is inserted into the printing device. Since the adapter terminals are "embedded" in this manner, they are firmly fixed against movement in both the mounting direction and the direction opposite to the mounting direction. Therefore, there is less likelihood of misalignment or separation between the adapter terminals and the device side contact-forming elements as compared with the one-sided ones Restriction by the elastic piece 40 and the associated structure of the U.S. Patent No. 7,008,053 ,

Application 1

If the adapter is attached to the printing device, if the adapter is held too tight, contact with some of the device-side contact forming elements (e.g. 734 in the 31 ) not sure. By disposing the engaging portion of the first restricting portion to the left of the rightmost contact portion of the plurality of terminals and to the right of the leftmost contact portion of the plurality of terminals, the adapter may tilt sufficiently so that the electrical connection between the plurality of terminals and the device side contact forming elements is more stable can be.

When the engaging portion of the second restricting portion is located farther from the plane defined by the leading edge than the engaging portion of the first restricting portion, the likelihood that the first restricting portion is disengaged from the apparatus-side engaging portion compared with the case where the engaging portion of the first restricting portion farther away from the plane defined by the leading edge than the engaging portion of the second restricting portion is more effectively decreased.

When the distance between the engaging portion of the first restricting portion and the plane defined by the leading edge is smaller than the distance between a pivot point of the lever and the plane defined by the leading edge when the adapter is mounted, the lever serves to move the adapter restrict. This reduces the likelihood that the first restricting portion will be released or disengaged from the engaging portion of the lever, thereby creating a stable electrical connection between the plurality of terminals and the contact forming elements and reducing the likelihood of poor continuity. The first restricting portion may move about the rotational axis of the lever when a force is applied from the contact forming members to the attached adapter. This reduces the likelihood that the engaging portion of the first restricting portion is decoupled from the engaging portion of the lever.

When the adapter is mounted so that the engaging portion of the first restricting portion is to the left of a fulcrum of the lever, when the adapter is viewed from the side so that the engaging portion of the first restricting portion is right and the liquid supplying structure is facing down, the first restricting portion generates a torque on the lever to rotate the lever about the axis of rotation of the lever in the direction opposite to the release direction. This reduces the likelihood that the engaging portion of the first restricting portion will be released from the engaging portion of the lever, and further ensures the stable electrical connection between the plural terminals and the apparatus-side contact forming members.
