In addition, the middle targeting part 20 of gathering sill 16 comprises and temporarily stops sidewall sections 20a, when wherein said sidewall sections 20a has been inserted into box mounting portion 101 to the enough degree of depth at print cartridge 1, will be before temporarily stopping at standing part 18 along the steady pin 112 that moves on the direction of standing part 18.Sidewall sections 20a is corresponding to the part 116a3 of peripheral wall 116a.

In addition, the standing part 18 of gathering sill 16 comprises and finally stops sidewall sections 18a, wherein said sidewall sections 18a is extracting out on the direction by when pushing back when being inserted into box mounting portion 101 to the print cartridge 1 of enough degree of depth, on the precalculated position, admit and stop that sidewall 20a unclamps and to the steady pin 112 that standing part 18 moves, stop steady pin 112 thus from temporarily stopping.Sidewall sections 18a is corresponding to the left-half of protruding 216f.

In addition, at the initiating terminal formation crooked sidewall part 21a of outlet side targeting part 21, crooked sidewall part 21a continuity and formation straight line inclined surface 21b in addition, form straight line flat 21c from inclined surface 21b continuity since then.

Therefore, gathering sill 16 comprises the first smooth bottom parts, this first bottom parts is corresponding to second bottom parts of flat 19b and guiding inclination, this second bottom parts is corresponding to the inclined surface 19a and the 3rd smooth bottom parts that leads, the 3rd bottom parts is corresponding to the end portion of entrance side targeting part 19, middle targeting part 20, the beginning part of standing part 18 and outlet side targeting part 21, and the 4th bottom parts of guiding inclination, the 4th bottom parts is corresponding to the inclined surface 21b and the 5th smooth bottom parts that leads, and the 5th bottom parts is corresponding to flat 21c.Shown in Figure 15 (A), first and second bottom parts are arranged along the first straight line L1, the 3rd bottom parts corresponding to part 20 and 18 and the part of part 21 beginning part arrange that along the second straight line L2 the 4th and the 5th bottom parts is arranged along the 3rd straight line L3 approx.The second straight line L2 and the 3rd straight line L3 are with right angle intersection.In addition, gathering sill 16 is parallel with the basal surface of print cartridge with the bottom surface of the 5th bottom parts corresponding to the first, the 3rd.

In addition, the exit portion 16b of gathering sill 16 is connected to intake section 16a, and gathering sill 16 forms a ring on the whole thus.In the coupling part between intake section 16a and exit portion 16b, the groove depth of exit portion 16b is more shallow than the groove depth of intake section 16a, has formed step part 23 (shown in Figure 16 B) thus in the coupling part.This step part 23 prevents to enter when steady pin 112 is among print cartridge 1 is inserted into box mounting portion 101 flat 21c.

Then, will be described in the operation of steady pin 112 among gathering sill 16 in the installation and removal operation of print cartridge 1 with reference to Figure 17.Should be appreciated that the arrow Z among Figure 17 represents the direction of pushing by the dwang parts 108 that bias caused of spring members 109.

Among print cartridge 1 is inserted into box mounting portion 101 and after being connected on the slider part 102, when the pushing force of resisting slider part 102 when print cartridge 1 on direction of insertion X was further promoted, the steady pin 112 of dwang parts 108 was inserted into the intake section 16a (the position A among Figure 17) of gathering sill 16 by opening portion 22a, 22b, the 22c of print cartridge front surface.

Because inlet inclined surface 22 is formed on the intake section 16a of gathering sill 16, moving in the opposite direction with groove depth side at the steady pin 112 that slides on this inlet inclined surface 22.Thus, the parts generation strain of dwang parts 108 or support dwang parts 108 is so produced the power of pushing steady pin 112 towards the basal surface of gathering sill 16.

When the front end of steady pin 112 at first contacted with inlet inclined surface 22, the top surface of pin mounting portion 111 was positioned at the position lower than the marginal water plane of gathering sill 16.When steady pin 112 was mobile on inlet inclined surface 22, groove depth changed, and made the top surface of pin mounting portion 111 exceed the marginal water plane of gathering sill 16.

When steady pin 112 is gone up (the position B in Figure 17) by the inlet inclined surface 22 and the flat 19b that arrives soon after, have only steady pin 112 to be inserted in the gathering sill 16, and pin mounting portion 111 is positioned at the outside of gathering sill 16.This is because the degree of depth of gathering sill 16 at flat 19b place is set to the length less than steady pin 112.

By being the intake section 16a outfit inlet inclined surface 22 of gathering sill 16 like this, can be when steady pin 112 be inserted among the intake section 16a of gathering sill 16, prevent that steady pin 112 from being blocked by the front surface of print cartridge 1, so can be smoothly and carry out steady pin 112 insertion among the intake section 16a of gathering sill 16 reliably.

In addition, because formed inlet inclined surface 22, and the groove depth of the flat 19b of surface 22 continuities from then on is set to the length less than steady pin 112, even the width of the groove of part 16a continuity is made narrower so be set to more greatly and since then at the width of gathering sill 16 intake section 16a, just as in this embodiment, sell the narrow width segments that mounting portion 111 can not be stuck in gathering sill 16 yet.Be provided with greatlyyer by the width with gathering sill 16 intake section 16a, steady pin 112 can be inserted in the gathering sill 16 reliably.

When print cartridge 1 was further promoted on direction of insertion X, steady pin 112 passed through flat 19b, and moves (the position C among Figure 17) on the groove depth direction, formed on the inclined surface 19a at deep trouth and slided.

When steady pin 112 formed inclined surface 19a and comes the position (the position D among Figure 17) of flat 19c by deep trouth, the peripheral part of pin mounting portion 111 top surfaces cooperated with the marginal portion of gathering sill 16, and tightly suppresses this marginal portion.This is because the lasting strain that also still exists at this moment that produces in dwang parts 108 when steady pin 112 passes through inlet inclined surface 22.Cooperate with the marginal portion of gathering sill 16 by the peripheral part that will sell mounting portion 111 top surfaces like this, can prevent that dwang parts 108 from contacting with the surface (basal surface of sunk part 17) of the marginal portion that comprises gathering sill 16, prevents that thus steady pin 112 from rising to outside the gathering sill 16.

In addition, when steady pin 112 was come the position (the position D among Figure 17) of flat 19c, the front end of steady pin 112 separated with the basal surface of gathering sill 16.This is because the groove depth of flat 19c is set to the length greater than steady pin 112.

When print cartridge 1 is further promoted on X on the direction of insertion, and when steady pin 112 surpassed near the front end at place, end that convex wall part 19d is arranged in entrance side targeting part 19 position (the position E of Figure 17), steady pin 112 moved on direction Z by the pushing force of spring members 109.So steady pin 112 is run into and is temporarily stopped sidewall 20a and stop (the position F among Figure 17).At this moment, the click sound that can hear of generation.In case hear this click sound, the user can confirm that print cartridge 1 has been inserted into enough degree of depth.

Go up when print cartridge 1 is exerted pressure when the user stops at direction of insertion X, extracting out on the direction Y (promptly towards the user) a little to pusher print cartridge 1 by the pushing force of slider part 102.Thus, steady pin 112 is with temporarily to stop to engage of sidewall 20a released, and steady pin 112 moves on direction Z in response to the pushing force of spring members 109.Subsequently, steady pin 112 collides with finally stopping sidewall 18a, and stops on the fixed position (the position G among Figure 17), and produces the click sound that can hear at this moment.By hearing this click sound, the user can confirm that print cartridge 1 has been correctly fitted on the box mounting portion 101.

, be similar to the groove depth among the flat 19c of entrance side targeting part 19 herein, the degree of depth of groove is set to the length greater than steady pin 112 in gathering sill 16 standing parts 18.In addition, by the strain that dwang parts 108 produce, push steady pin 112 when steady pin 112 passes through inlet inclined surface 22 towards the basal surface of gathering sill 16.

Therefore, for the steady pin 112 that is fixed on the predetermined fixed position that stops part 18, its whole length has entered into the inside of gathering sill 16, and the peripheral part of pin mounting portion 111 top surfaces cooperates with the marginal portion of gathering sill 16.Thus, cooperate the sidewall of gathering sill 16 can be used for preventing that steady pin 112 (its bottom specifically) from taking place by the creep that power caused that is applied on the steady pin 112 like this.Promptly under steady pin 112 is inserted in situation in the gathering sill 16 more shallowly, the power on steady pin 112 bottoms of being applied to is owing to lever principle increases.Yet, in the present embodiment,, can prevent the creep of steady pin 112 because whole length of steady pin 112 are inserted in the gathering sill 16 as mentioned above.

In addition, because steady pin 112 enough is inserted in the gathering sill 16 deeply, so steady pin 112 can not gone to outside the gathering sill 16.This effect is not limited only to standing part 18, and under the situation of sliding along the marginal portion of gathering sill 16 in the peripheral part of pin mounting portion 111 top surfaces, when steady pin 112 relatively moves, also obtains this effect in gathering sill 16.

In addition, spring members 109 is pushed steady pin 112 towards a side surface of print cartridge 1, and the electrode 8a of memory cell 8 is provided in this side surface.Therefore, the pushing force of spring members 109 is by steady pin 112 and finally stop sidewall sections 18a effect, so that the electrode 8a of memory cell 8 is pressed towards device side contact 113 (Fig. 9 and Figure 10).Thus, can guarantee the electrode 8a of memory cell 8 and the connection between the device side contact 113.

Then, when 101 dismountings are during print cartridges 1 from the box mounting portion, the user promotes print cartridge 1 slightly on direction of insertion X.So steady pin 112 is with finally to stop to engage of sidewall 18a released, and steady pin 112 moves on direction Z in response to the pushing force that is applied by spring members 109.Then, the crooked sidewall 21a collision of steady pin 112 and gathering sill 16 outlet side targeting parts 21, and temporarily stop (the position H among Figure 17).At this moment, the click sound that can hear of generation.The user hears click sound, just can confirm that print cartridge 1 is released to fixing of box mounting portion 101.

Then, the user stops on the direction of insertion X print cartridge 1 is exerted pressure.Extracting out on the direction Y when mobile in response to the pushing force of slider part 102 when print cartridge 1, steady pin 112 moves (the position I among Figure 17) along the straight line inclined surface 21b of outlet side targeting part 21.At this moment, the front end of steady pin 112 contacts with inclined surface 21b in the centre of inclined surface 21b, and steady pin 112 is moving up in the opposite direction with groove depth side.The steady pin 112 that has passed through inclined surface 21b passes through flat 21c (the position J among Figure 17), and comes out from the exit portion 16b of gathering sill 16.

The connection procedure of print cartridge 1 and ink feed pin 106 grades then, will be described when print cartridge 1 is installed on the box mounting portion 101.
