Definitions
- the invention generally relates to ink jet printing, and in particular to apparatus for securing a print cartridge in an ink jet printer.
- BACKGROUND OF THE INVENTION Inkjet printers are well known.
- One common type of ink jet printer uses a replaceable print cartridge that is loaded into a scanning carriage in an ink jet printer. The scanning carriage scans across a paper sheet to print a swath of ink on the sheet, using a print head on the cartridge.
- a print cartridge which in one embodiment has a porous ink-absorbent, such as a sponge, and a print head in ink communication with the porous ink-absorbent.
- the print cartridge is refilled with the print ink by vertically lowering an ink supply into a nest in the print cartridge.
- An ink conduit needle erect at the bottom of the nest vertically pierces a septum at the bottom of the ink supply. This enables the print ink to flow from the ink supply to the porous ink-absorbent via a capillary tube in the print cartridge.
- an ink jet printer including a replaceable print cartridge which is vertically lowered into a stall on the scanning carriage.
- an ink conduit needle on the cartridge vertically pierces an upstanding septum on the scanning carriage. This allows a flexible ink delivery tube interconnecting the septum and a stationary ink supply source separate from the scanning carriage to flow the print ink to the print cartridge.
- An ink jet printer apparatus for securing a print cartridge which includes: an open container having a top opening; a porous ink-absorbent in the container; a print head in ink communication with the porous ink-absorbent; a top cover lid adapted to be placed on the container, over the top opening, to close the container; and an ink conduit needle mounted on the top cover lid to longitudinally extend in a horizontal orientation above the porous ink-absorbent when the cover lid is placed on the container, so that a print ink can descend freely by the force of gravity from the ink conduit needle onto the porous ink-absorbent and from the porous ink-absorbent down to the print head, said apparatus comprising: a resilient septum; an ink delivery connection to the septum; a stall for receiving the print cartridge in a substantially horizontal direction so that the ink conduit needle mounted on the top cover lid is horizontally inserted through or pierces the septum; and a cover door
- FIG. 1 is an exploded perspective view of a print cartridge
- FIG. 2 is an assembled perspective view of the print cartridge
- FIG. 3 is a side perspective view of an ink jet printer scanning carriage, including a stall for receiving the print cartridge
- FIG. 4 is an exploded perspective view of an ink delivery assemblage on the scanning carriage for flowing a print ink to the print cartridge from a stationary ink supply source separate from the scanning carriage, and of a cover door that when closed secures the print cartridge in place on the scanning carriage; and
- FIG. 5 is a side elevation view in cross-section of the print cartridge and the ink delivery assemblage.
- DETAILED DESCRIPTION OF THE INVENTION The invention is depicted as embodied in an ink jet printer. Because the features of such a printer are generally known, the detailed description which follows is directed only to those elements forming part of or cooperating with the invention. It is to be understood, however, that other elements not described may take various forms known to a person of ordinary skill in the art.
- a box-like container 12 of the print cartridge 10 has a pair of parallel planar side walls 14 and 16, a pair of parallel planar end walls 18 and 20, and a stepped bottom wall 22. There is no top wall, so that there is a rectangular- shaped top opening 24 as shown in FIG. 1.
- a porous ink-absorbent 26, such as a foam or sponge block, is fitted tightly in the container 12 to abut the side, end and bottom walls 14, 16 18, 20 and 22 of the container, and also to be adjacent the top opening 24 of the container, as shown in FIGS. 1 and 5.
- a print head 28 at an opening 30 in the bottom wall 22 of the container 12 is in gravity- flow ink communication with the porous ink-absorbent 26 in the container.
- a top cover lid 32 is adapted to be placed on the container 12, over the top opening 24 in the container, to close the container at the top opening. See FIGS. 2 and 5.
- a hollow ink conduit needle 34 is mounted in the top cover lid 32 to be positioned spaced above the porous ink-absorbent 26 in the container 12 when the top cover lid is placed on the container as shown in FIG. 5. This allows a print ink 38 to vertically descend freely by the force of gravity from the ink conduit needle 34, through the top opening 24 in the container 12, onto the porous ink-absorbent 26, in order for the print ink to accumulate vertically on the porous ink-absorbent to a maximum ink level 40 as shown in FIG. 5.
- the ink conduit needle 34 longitudinally extends in a horizontal orientation above the ink absorbent 26 when the top cover lid 32 is on the container 12.
- the top cover lid 32 forms an air chamber 42 between the ink conduit needle 34 and the porous ink-absorbent 26 when the top cover lid is on the container 12. See FIG. 5.
- the top cover lid 32 has an open shroud 44 for the ink conduit needle 34.
- Scanning Carriage A scanning carriage 46 in an ink jet printer is movable along a slide rod 48 to scan across a paper sheet (not shown), in order to print a swath of the print ink 38 on the paper sheet as in prior art U.S. Patent No. 5,980,032 issued Nov. 9, 1999. See FIG. 3.
- the scanning carriage 46 includes a resilient rubber horizontally pierceable septum 50, a rigid tubular or cylindrical support 54 for the septum, and a mounting support or bracket 56 for the tubular support, as shown in FIGS. 3-5.
- the septum 50 is fixed to the tubular support 54.
- the tubular support 54 longitudinally extends through a wall hole 58 in the mounting support 56 and is secured to the mounting support via a c-shaped fastener clip 60. See FIG. 4.
- the mounting support 56 is secured to the scanning carriage 46 by a pair of fastener detents or clips 61 , 61 that extend into respective holes (not shown) in the scanning carriage.
- a flexible ink delivery tube 64 is connected at one end to the tubular support 54 and at another end to a stationary ink reservoir (not shown) which is separate from the scanning carriage 48.
- a stall 66 on the scanning carriage 48 is configured to receive the print cartridge 10 in a substantially horizontal direction 68, so that the ink conduit needle 34 mounted in the top cover lid 32 of the print cartridge is horizontally inserted through or pierces the septum 50 as shown in FIG. 5. If the horizontal direction 68 is considered to be along an X-axis, the tubular support 54 is fixed along that axis, but may slightly adjust (0.025") along Y- and Z-axis. When the ink conduit needle 34 extends longitudinally through the septum 50 as shown in FIG.
- the septum 50 can have some known means (not shown) to facilitate insertion of the ink conduit needle 34 through the septum 50, such as a pre-pierced cylindrical hole in the septum which has a diameter that is less than the diameter of the needle, or a pre-pierced center slit in the septum, or a leading indentation. It is important that the septum 50 snugly embraces the needle 34 when the needle longitudinally extends through the septum, so that there can be no air between the needle and the septum.
- the ink conduit needle 34 has an ink ingress opening 74 and an ink egress opening 76 as shown in FIG. 5, in order for the print ink 38 to flow into and out of the needle and then gravity descend from the ink egress opening, through the top opening 24 in the container 12, onto the porous ink-absorbent 26 in the container.
- the print ink 38 then drains to the print head 28 at the bottom opening 30 in the bottom wall 22 of the container 12
- a flexible (ribbon) electrical circuit 78 supported on a spring pad 80 on the scanning carriage 46 contacts a corresponding circuit 82 on the end wall 20 of the container 12 of the print cartridge 10, when the print cartridge is loaded in the stall 60. See FIG. 4.
- the print cartridge 10 is supported in the stall 60 at (at least) three datum surfaces Dl, D2 and D3 on the container 12. See FIG. 5.
- a pair of pins 83, 83 project at one of their ends through bottom holes (not shown) in the mounting support 56 and project at opposite ends into top holes 85, 85 in the flexible circuit 78.
- a cover door 84 has coaxial projections 86, 86 that protrude into respective wall holes 88, 88 in the mounting support 56 to pivotally support the cover door on the mounting support as shown in FIG. 4. When the cover door 84 is pivoted down counter-clockwise in FIG. 3, it closes to firmly hold or secure the print cartridge 10 in the stall 66.
- the cover door 84 includes a spring-urged cartridge retainer 90 that is pivotally supported on the cover door, such as by coaxial pins in respective slots (not shown), and is urged to pivot counterclockwise by a helical compression spring 92 in FIG. 4 for this purpose.
- the retainer 90 is brought to bear firmly against an inclined face or surface 94 on the top cover lid 32 of the print cartridge 10. See FIG. 3. This acts to ensure that the ink conduit needle 34 mounted in the top cover lid 32 cannot be dislodged from the septum 50 and that the print cartridge 10 is properly positioned in the stall 66 by being supported at the datum surfaces Dl, D2 and D3 on the container 12.
- the retainer 90 acts to ensure that the flexible circuit 78 supported on the spring pad 80 on the scanning carriage 46 remains in contact with the corresponding circuit 82 on the print cartridge 10.
- the retainer 90 has an inclined face or surface 96 that complements the inclined face 94 on the top cover lid 44.
