Preferably, one end of elastic component is connected with detected component, and the other end of elastic component is connected with protecting cover, so that It is easy to carry out assembly and disassembly to Delevoping cartridge.

According to another specific embodiment of the present utility model, detected portion can have and the portion of elastic deformation can occur Point.It is such to be advantageous in that, can reduce when detected portion is contacted with the detection unit of imaging device and the detection unit is rushed (when detection unit uses contact measurement mode) is hit, and is prevented caused by detected portion and other objects collide It is detected component damage.

According to another specific embodiment of the present utility model, transmission mechanism also includes around parallel with first rotation axis The central rotational component of the 4th pivot axis, central rotational component directly drives inspection in the presence of driving force receiving member Drive member is surveyed to rotate；Under the drive of central rotational component, detection drive member turns to the second place from first position, and When the second place is turned to, detection drive member will be rotated no longer with central rotational component.Selectively, driving force receives structure Part can directly coordinate with detection drive member and drive drive member to rotate.

More specifically, detection drive member is included in its rotation direction the multiple trigger units being spaced apart successively, in inspection Survey in the rotation process of drive member, multiple trigger units apply force to detected component successively so that be detected component and exist Moved back and forth between initial position and test position.

In the utility model, the information related to Delevoping cartridge can be represented by being detected the detected number of times of component. For example, when detected component is carried out 1 detection, carbon dust amount that Delevoping cartridge accommodated is represented as " high power capacity " (can be beaten Printed page number is more), when detected component is carried out 2 detections, carbon dust amount that Delevoping cartridge accommodated is represented as " low capacity " (can Number of print pages is less).

In above-mentioned technical proposal, touched because detection drive member is included in the multiple being spaced apart successively in its rotation direction Hair portion so that be detected component and moved back and forth between initial position and test position, even if therefore when the quantity of detected portion For one when, the detected portion can also be by repeated detection so that can be without such as prior art (such as Chinese patent literature CN 1828446 B) in equally need to set multiple detected portions and realize repeated detection being detected on component, so as to quilt can be simplified The structure of detection means.

In the utility model, various transmission fit systems can be used between central rotational component and detection drive member. For example, referring to disclosed in Chinese patent literature CN100470394C, central rotational component includes complete gear, and detection drives structure Part includes partial gear, and under the drive of central rotational component, detection drive member turns to the second place from first position, And when the second place is turned to, detection drive member will be rotated no longer with central rotational component.And for example, with reference to Chinese patent text Offer disclosed in the B of CN 102331699, central rotational component includes complete gear, detection drive member includes castle wheel, clutch Wheel has the path part and the large diameter portion with the tooth top interference fit of complete gear coordinated with the tip clearance of complete gear, Large diameter portion, by elastic-friction layer and the tooth top interference fit of gear, detects drive member circumferentially arranged with elastic-friction layer The second place is turned to from first position, and when the second place is turned to, detection drive member will no longer with central rotational structure Part is rotated.

Used as a kind of preferred embodiment, central rotational component has around the arc-shaped convex surface of the 4th pivot center (i.e. Arc-shaped convex surface is set with central rotational component coaxial), detect that drive member has and be formed as what is be engaged with arc-shaped convex surface Arc-shaped concave surface；Wherein, in central rotational component and detection drive member has pin, and central rotational component and detection are driven Another in dynamic component has groove；When pin card is together in groove, central rotational component drives detection drive member to rotate；When pin is de- During from groove, arc-shaped convex surface engages with arc-shaped concave surface, to prevent detection drive member from rotating.

Wherein, during detection drive member turns to the second place from first position, pin and groove both can only block Close 1 time, it is also how multiple (such as 3 times, 5 times) with engaging.That is, detection drive member can routinely by first position Turn to the second place (when pin and groove engage 1 time), it is also possible to the second place is intermittently turned to by first position and (works as pin When repeatedly engaging and groove between).

In above-mentioned technical proposal, on the one hand, because central rotational component drives detection by the engaging between groove and pin Drive member is rotated, therefore is capable of achieving stable drive between central rotational component and detection drive member, so as to realize Delevoping cartridge Reliable and stable detection；On the other hand, due to not including gear drive between central rotational component and detection drive member, Therefore the cost of Delevoping cartridge can effectively be reduced.

On the other hand, in the B of Chinese patent literature CN 102331699, between gear and the large diameter portion of castle wheel It is driven by frictional force, but due to the unstability of frictional force, the program exists and passed between gear and the large diameter portion of castle wheel The dynamic defect being not sufficiently stable；In Chinese patent literature CN100470394C, using the detection with toothless portion) and contact protrusion Gear detects whether Delevoping cartridge is new and/or Delevoping cartridge carbon dust capacity, but the program exist detection gear manufacture it is difficult The deficiency that degree is big, installation accuracy requirement is high.

Protecting cover 3 and the transmission mechanism 4 covered by protecting cover 3 are provided with the first side wall 11, transmission mechanism 4 includes driving force Receiving member 41, developer roll drive gear 42, the first idler gear 43, the second idler gear 44 and detection drive member 45.Its In, driving force receiving member 41 is rotated around first rotation axis parallel with the longitudinal direction of box body 1, and stretch out in protecting cover 3 it Outward, for receiving driving force from electrophotographic image forming；The gear of developer roll drive gear 42 and driving force receiving member 41 Engage in portion；First idler gear 43 is two-stage gear, and its inner toothed portion is engaged with the gear part of driving force receiving member 41, external tooth The second idler gear of part 44 is meshed；Detection drive member 45 and the phase of the second idler gear 44 around the 4th pivot axis Coordinate, and around second rotation axis rotation, the 4th pivot center and second rotation axis under the drive of the second idler gear 44 It is parallel with first rotation axis.Thus, by the transmission of the first idler gear 43 and the second idler gear 44, detection drives structure Part 45 is rotated under the drive of driving force receiving member 41.

Fig. 3 is the stereogram of protecting cover 3, it illustrates the structure of the inner side of protecting cover 3.Fig. 4-5 is the second idler gear 44, detection The stereogram of drive member 45 and detected component 5.Understood with reference to Fig. 1-5, be formed with protecting cover 3 for for being detected component 5 The opening portion 31 extending out to outside protecting cover 3 and pivotal axis 32 substantially perpendicular with first rotation axis, are detected component 5 Base portion 52 be rotatably connected on pivotal axis 32, and be detected component 5 around perpendicular substantially with first rotation axis Third rotation axis are rotated.It is provided between protecting cover 3 and detected component 5 as the spring 6 of elastic component, the one of spring 6 End is connected on protecting cover 3, and the other end is connected on detected component 5；Spring 6 is configured to apply active force to detected component 5, To cause that be detected component 5 rotates or be maintained at the initial position to its initial position.The inner side of protecting cover 3 is additionally provided with positioning Support shaft 33, position support shaft 33 is engaged with the axis hole 454 of detection drive member 45, is driven with positioning simultaneously Auxiliary support detection Component 45.

With continued reference to Fig. 4-5, the second idler gear 44 is included in what is be spaced apart on the direction of the 4th pivot center Multiple pins 441 and multiple (i.e. axis on arc-shaped convex surface 442 and the 4th of arc-shaped convex surface 442 around the 4th pivot center Pivot center is conllinear), and pin 441 and arc-shaped convex surface 442 be arranged alternately successively.Thus, the second idler gear 44 has sheave The structure of driver plate in mechanism.It is readily appreciated that, the quantity on pin 441 and arc-shaped convex surface 442 can be one or more.

Detection drive member 45 includes that multiple grooves 451 and the multiple arc-shapeds between two adjacent grooves 451 are recessed Face 452, and groove 451 is configured to coordinate with pin 441, arc-shaped concave surface 452 is configured to be engaged with arc-shaped convex surface 442.Thus, Detection drive member 45 has the structure of sheave in Geneva mechanism, and is configured to incomplete sheave.It is readily appreciated that, the number of groove 451 Amount can also be one.

That is, the second idler gear 44 and detection drive member 45 constitute incomplete Geneva mechanism, and the second idler gear 44 Detection drive member 45 is driven to rotate as central rotational component.Specifically, when pin 441 is sticked in groove 451, the second center tooth Wheel 44 drives detection drive member 45 to rotate；When 441 releasing slots 451 of pin, arc-shaped convex surface 442 is blocked with arc-shaped concave surface 452 Close, to prevent detection drive member 45 from rotating.Under the drive of the second idler gear 44, drive member 45 from first position is detected The second place is intermittently turned to, and when the second place is turned to, detection drive member 45 will no longer with detection second Between gear 44 rotate.

Fig. 6 is the front of the second idler gear 44, detection drive member 45 and detected component 5 (i.e. in face of the one of protecting cover 3 Face) view, Fig. 6 is the back side of the second idler gear 44, detection drive member 45 and detected component 5 (i.e. in face of the first side wall 11 one side) view；Wherein, shown by Fig. 6 and 7 be detect drive member 45 be located at first position when state.

As shown in Fig. 4 to 7, (when Delevoping cartridge is new), Duo Gexiao when detecting that drive member 45 is located at first position One in 441 fastens with the groove 441 that most downstream side is located in the rotation direction of detection drive member 45 just so that the Two idler gear 44 drives detection drive member 45 intermittently to be rotated from first position to the second place；When pin 441 and in inspection When surveying in the rotation direction of drive member 45 phase separation of groove 441 for being located at most upstream side, detection drive member 45 turns to second Position (not shown).Because detection drive member 45 is configured to incomplete sheave, thus when detection drive member 45 turns to the Behind two positions, it no longer will be rotated with the second idler gear 44, and (but detection drive member 45 may be because of itself in second position Gravity and make the deflection of low-angle, to reach gravitational equilibrium position).

During detection drive member 45 turns to the second place by first position, the triggering of drive member 45 is detected Portion 453 applies force to the forced section 53 of detected component 5 so that be detected the elasticity resistance that component 5 overcomes spring 6 to be applied Power, test position is moved to the detected portion 51 for driving detected component 5 by initial position.Matched somebody with somebody due to being detected component 5 It is set to and is rotated around the pivotal axis 32 substantially perpendicular to first rotation axis, thus in detected component 5 around third rotation axis While rotating (namely being rotated around pivotal axis 32), detected portion 51 has remote on the direction parallel to first rotation axis From the component motion of the first side wall 11.Wherein, trigger unit 453 is configured in the downstream by the rotation direction of detection drive member 45 Onto the direction of upstream side, its surface in detection drive member 45 radially is gradually distance from the rotary shaft of detection drive member 45 Line, to cause the motion for being detected component 5 more steady.It is readily appreciated that, trigger unit can also can be driven tested using other Structure and shape that component is rotated are surveyed, for example with the cam being coaxially disposed with detection drive member.

Fig. 8 is the top view of the second idler gear 44, detection drive member 45 and detected component 5.Wherein, it is shown in solid The detected component 5 for going out is the position when detected portion 51 is located at original state, and the detected component 5 shown by dotted line is to work as Detected portion 51 is located at the position during state of being detected.As seen from Figure 8, on the direction parallel to first rotation axis, it is detected Survey portion 51 is in initial position ratio in test position closer to the first side wall 11.When test position is reached, detected portion 51 will Detected by the detection unit of electrophotographic imaging forming apparatus, the information of Delevoping cartridge is related to obtain (for example, being detected component 5 The detection unit of detected portion 51 and electrophotographic image forming come in contact or be detected unit and sensed).

Although shown in Fig. 8 is that first rotation axis and third rotation axis are vertical (angle of the two is 90 degree) Situation, but it should be readily apparent to one skilled in the art that when first rotation axis and third rotation axis are intersecting, for example therebetween Angle be more than or equal to 30 degree, less than 90 degree, or more than or equal to 60 degree, less than or equal to 90 degree, or more than or equal to 80 degree, be less than Deng 90 degree, during detected component 5 is rotated, detected portion 51 can be equally controlled parallel to first rotation axis Gradually increase with the distance between the first side wall 11 on direction.

In the present embodiment, detected portion 51 has and the part (such as elastomer block) of elastic deformation can occur, tested to reduce To the impact of the detection unit (when detection unit uses contact measurement side when survey portion 51 contacts with the detection unit of imaging device During formula), and prevent the detected component 5 caused by detected portion 51 may collide with other objects from damaging.
