Complete print cartridge 30 is installed to box installation portion 110 after, printer 10 begins to print.When the China ink of storage in black chamber 36 was finished by printer 10, the print cartridge 30 of using was removed from box installation portion 110, and new print cartridge 30 is installed to box installation portion 110.
[print cartridge 30 is removed from box installation portion 110]
When intention was removed print cartridge 30 from box installation portion 110, the rearward end 82 of pivot member 80 was pushed downwards by the user.Therefore, the leading section 81 of pivot member 80 moves up and separates with roof 39.When this happens, engagement member 145 is by the upwards pushing of the leading section 81 of pivot member 80, and the abutting end 146 of engagement member 145 moves to the position of composition surface 46 tops, namely moves to the position of separating with composition surface 46.So, engagement member 145 moves to unlocked position from latched position, and print cartridge 30 is by the status releasing from being kept by engagement member 145.
When abutting end 146 separated with composition surface 46, the biasing force that is applied to external force, for example helical spring 139 of print cartridge 30 made print cartridge 30 move removing on direction 55.Yet, because user's finger still contacts with the rearward end of depressing 82 of pivot member 80, so removing print cartridge 30 mobile on direction 55 by user's stop.The biasing force of helical spring 139 is received by user's finger via pivot member 80.
When the user moved his/her finger on dismounting direction 55, print cartridge 30 was by slider 135 and helical spring 139 pushings and follow the finger movement.When this happens, the IC plate 74 that is arranged on carriage 90 is removed by the downward bias pressure from the contact 106 of box installation portion 110.When print cartridge 30 is being removed the finger of following the user on direction 55 and is being moved, the slidingsurface 148 of engagement member 145 above recess 78 through and slide on IC plate 74 and slope 49.When slidingsurface 148 slided on thermode 75, earth electrode 76 and signal electrode 77, dust was wiped from thermode 75, earth electrode 76 and signal electrode 77.After sliding on slope 49, slidingsurface 148 passes through above groove 87.When this happens, the dust of being wiped by slidingsurface 148 is fallen in groove 87.Therefore, the dust possibility around the part of ink supply opening 71 that falls and be adhered to ink supply section 34 reduces.
Simultaneously, the outer surface of bar 125 separates with the inner surface 98 of the restriction opening 96 of carriage 90, makes carriage 90 be moved down into initial position with respect to main body 31, and carriage 90 is supported by the upper surface of the front portion of main body 31 in this initial position.China ink pipe 122 is drawn out ink supply section 34.So, print cartridge 30 is removed from box installation portion 110.
[advantage]
In this embodiment, because print cartridge 30 comprise be configured to by with IC plate 74 test section 89 and the ribs 88 that detect of optical pickocff 114,116 independently, even the electrical connection between IC plate 74 and contact 106 can not be set up or data can not be read from IC via signal electrode 77, based on determining that from the information of test section 89 and rib 88 acquisitions print cartridge 30 is installed to printer 10.Therefore, even the electrical connection between IC plate 74 and contact 106 can not be set up or data can not be read from IC via signal electrode 77, also can use print cartridge 30.
In this embodiment, because advance in the direction vertical with direction of insertion 50 (width, left and right directions) from the light of optical pickocff 114,116 emissions, so test section 89 and rib 88 can be on direction of insertion 50 entered optical pickocff 114,116 test point (light path) with the timing of hope.And, because thermode 75, earth electrode 76 and signal electrode 77 can be accessible on the direction that the downward direction vertical with direction of insertion 50 and light are advanced, so even thermode 75, earth electrode 76 and signal electrode 77 are accessed on downward direction by contact 106, make print cartridge 30 move up downwards, this movement does not affect test section 89 and rib 88 in the enterprising timing that enters optics sensor 114,116 test point (light path) of direction of insertion 56 yet.This is because this timing is determined by the movement of print cartridge 30 on direction of insertion 56, rather than moving down by print cartridge 30 determined.As a rule, when event occured on the direction that is being perpendicular to one another, such event can be event and can not influencing each other independently.
In this embodiment, because thermode 75, earth electrode 76 and signal electrode 77 be between antetheca 40 and rear wall 42, directly do not received by thermode 75, earth electrode 76 and signal electrode 77 from the biasing force removing on direction 55 of slider 135 and helical spring 139.Therefore, the excessive loads possibility that is applied to thermode 75, earth electrode 76 and signal electrode 77 reduces.And China ink is reduced by the possibilities that China ink pollutes from ink supply section's 34 leakages and thermode 75, earth electrode 76 and signal electrode 77.
If IC plate 74 is arranged on antetheca 40 places in the face of direction of insertion 56, contact potentially unstable between thermode 75, earth electrode 76 and signal electrode 77 and contact 106 because print cartridge 30 by remove on direction 55, i.e. bias voltage on thermode 75, earth electrode 76 and signal electrode 77 and the direction that separates contact 106.Therefore, in this case, the elasticity of the deformation range of contact 106 and contact 106 will have to be set greatlyr, so that when even the biasing force by bias voltage print cartridge 30 moves away contact 106 when thermode 75, earth electrode 76 and signal electrode 77, guarantee to contact between thermode 75, earth electrode 76 and signal electrode 77 and contact 106.Yet the moderate finite deformation scope of contact 106 and larger elasticity may apply large biasing force to thermode 75, earth electrode 76 and signal electrode 77, i.e. excessive load may be applied to thermode 75, earth electrode 76 and signal electrode 77.And if IC plate 74 is arranged on antetheca 40 places, the China ink that has leaked from ink supply section 34 may arrive thermode 75, earth electrode 76 and signal electrode 77, and causes short circuit between thermode 75, earth electrode 76 and signal electrode 77.
In this embodiment, because thermode 75, earth electrode 76 and signal electrode 77 and junction surface 45 are arranged on the same side of print cartridge 30, i.e. roof 39 sides, thermode 75, earth electrode 76 and signal electrode 77 are adjacent to 45 location, ground, junction surface.Because when junction surface 45 contacts with engagement member 145, junction surface 45 determines that print cartridge 30 is with respect to the position of box installation portion 110 with regard to inserting/remove direction 50, and the thermode 75, earth electrode 76 and the signal electrode 77 that are adjacent to 45 location, junction surface can accurately be located with respect to contact 106 with regard to inserting/remove direction 50.
