[advantage]

In this embodiment, because print cartridge 30 comprise be configured to by with the IC plate 74 independently test section 89 that detects of optical pickocff 114,116 and rib 88, even if the electrical connection between IC plate 74 and contact 106 can not be set up or data can not read from IC via signal electrode 77, can determine that print cartridge 30 is installed to printer 10 based on the information obtained from test section 89 and rib 88.Therefore, even if the electrical connection between IC plate 74 and contact 106 can not be set up or data can not read from IC via signal electrode 77, also print cartridge 30 can be used.

In this embodiment, because the light launched from optical pickocff 114,116 is advanced in the direction (width, left and right directions) vertical with direction of insertion 50, so test section 89 and rib 88 can enter the test point (light path) of optical pickocff 114,116 in direction of insertion 50 with the timing of hope.And, because thermode 75, earth electrode 76 can be accessed by with signal electrode 77 on the direction of in downward direction advancing with light vertical with direction of insertion 50, even if so thermode 75, earth electrode 76 and signal electrode 77 are accessed in a downward direction by contact 106, print cartridge 30 is moved in a downward direction, this movement do not affect yet test section 89 and rib 88 direction of insertion 56 enterprising enter the timing of test point (light path) of optical pickocff 114,116.This is because this timing is determined by the movement of print cartridge 30 in direction of insertion 56, instead of determined by moving down of print cartridge 30.As a rule, when event occurring on direction perpendicular to one another, such event can be independently event and can not influencing each other.

In this embodiment, because thermode 75, earth electrode 76 and signal electrode 77 are between antetheca 40 and rear wall 42, the biasing force on dismounting direction 55 from slider 135 and helical spring 139 is not directly received by thermode 75, earth electrode 76 and signal electrode 77.Therefore, excessive loads is applied to the possibility reduction of thermode 75, earth electrode 76 and signal electrode 77.And ink leaks from ink supply 34 and thermode 75, earth electrode 76 and signal electrode 77 are reduced by the possibility that ink pollutes.

If IC plate 74 is arranged on antetheca 40 place in the face of direction of insertion 56, then thermode 75, earth electrode 76 and the contact potentially unstable between signal electrode 77 and contact 106 because print cartridge 30 by dismounting direction 55, i.e. bias voltage on the direction that thermode 75, earth electrode 76 and signal electrode 77 are separated with contact 106.Therefore, in this case, the deformation range of contact 106 and the elasticity of contact 106 will have to be set larger, even if so that when thermode 75, earth electrode 76 and signal electrode 77 move away contact 106 by the biasing force of bias voltage print cartridge 30, ensure the Contact of thermode 75, earth electrode 76 and signal electrode 77 and contact 106.But 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, and namely 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 place, the ink leaked from ink supply 34 may arrive thermode 75, earth electrode 76 and signal electrode 77, and causes thermode 75, short circuit between 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 side, thermode 75, earth electrode 76 and signal electrode 77 are adjacent to location, ground, junction surface 45.Because when junction surface 45 contacts with engagement member 145, junction surface 45 determines that print cartridge 30 is relative to the position of box installation portion 110 with regard to insertion/dismounting direction 50, and being adjacent to thermode 75, earth electrode 76 and the signal electrode 77 of locating at junction surface 45 accurately can locate relative to contact 106 with regard to direction 50 with regard to insertion/dismounting.

In this embodiment, because thermode 75, earth electrode 76 and signal electrode 77 to be positioned to regard to direction of insertion 56 than composition surface 46 forward, so each and the composition surface 46 of thermode 75, earth electrode 76 and signal electrode 77 and corresponding level-crossing, this plane is parallel with depth direction (fore-and-aft direction) 53 with short transverse (above-below direction) 52, during print cartridge 30 is inserted box installation portion 110, engagement member 145 slides on thermode 75, earth electrode 76 and signal electrode 77.Therefore the dust on thermode 75, earth electrode 76 and signal electrode 77 is wiped free of, and the possibility that thermode 75, earth electrode 76 and the electrical connection between signal electrode 77 and contact 106 become instability reduces.

In this embodiment, thermode 75, earth electrode 76 and signal electrode 77 are positioned at the top at least partially of the composition surface 46 at junction surface 45.Because engagement member 145 is configured to, because it is conducted oneself with dignity or the downward pivotable by spring-biased, wipe so the dust on thermode 75, earth electrode 76 and signal electrode 77 can be engaged component 145 with stronger downward force.And, the mobile range of engagement member 145 is limited, the not downward pivotable of engagement member 145 is made to exceed latched position, if thermode 75, earth electrode 76 and signal electrode 77 are positioned at the below of composition surface 46, then engagement member 145 can not contact with signal electrode 77 with thermode 75, earth electrode 76.Thus the position being in the top at least partially of composition surface 46 of thermode 75, earth electrode 76 and signal electrode 77 is conducive to the wiping function of engagement member 145.

In this embodiment, because thermode 75, earth electrode 76 and signal electrode 77 to be positioned to regard to direction of insertion 56 than the ink supply opening 71 of ink supply 34 backward, even if the dust be inserted in box installation portion 110 and/or when removing from box installation portion 110 thermode 75, earth electrode 76 and signal electrode 77 when print cartridge 30 is wiped, the possibility that this dust is adhered to the part around ink supply opening 71 of ink supply 34 also reduces.Therefore, ink is reduced by the possibility of contamination by dust.

In this embodiment, because recess such as groove 87 to be positioned to regard to direction of insertion 56 than thermode 75, earth electrode 76 and signal electrode 77 forward, each and groove 87 of thermode 75, earth electrode 76 and signal electrode 77 intersect with respective planes, this plane is parallel with depth direction (fore-and-aft direction) 53 with short transverse (above-below direction) 52, thermode 75, earth electrode 76 and signal electrode 77 are positioned at above groove 87, fall into groove 87 from the dust of thermode 75, earth electrode 76 and signal electrode 77 erasing.Therefore, dust falls and is adhered to the possibility reduction of the part around ink supply opening 71 of ink supply 34.

In this embodiment, because ink supply 34 is positioned at antetheca 40 place and thermode 75, earth electrode 76 and signal electrode 77 are positioned at roof 39 place, the ink splashed from ink supply 34 arrives and the possibility polluting thermode 75, earth electrode 76 and signal electrode 77 reduces.
