fig. 7B is a schematic view showing the positions of the respective parts of the counting assembly after the developing cartridge according to the present invention is mounted and counted.
As shown in the drawing, before the developing cartridge 10 is mounted to the drum assembly 20, the abutting portion 1532 is located outside the second through hole 132, the blocking portion 151e is not opposed to the urging portion 1533, and the toothed portion 151b of the counter 151 is engaged with the intermediate gear 16; when the developing cartridge 10 is mounted to the drum assembly 20 and the power receiving member 14 receives the driving force, the counting member 151 rotates in the direction indicated by r to start counting, at which time the abutting portion 1532 abuts against the first plate 21 of the drum assembly 20 and the urging portion 1533 moves in the second through hole 132 in a direction substantially parallel to the vertical direction; when the counting member 151 completes counting, the toothless portion 151c of the counting member 151 is opposed to the intermediate gear 16, and even if the power receiving member 14 continues to receive the driving force from the outside, the counting member 151 does not continue to rotate, and at the same time, the blocking portion 151e is blocked by the force applying portion 1533.
When the developing cartridge 10 is taken out of the drum assembly 20, the abutting portion 1532 is no longer abutted by the first side 21 of the drum assembly and returns to the state of being located outside the second through hole 132, and at the same time, the urging portion 1533 no longer blocks the blocking portion 151e, and under the elastic urging force of the elastic member 152, the counting member 151 rotates in the direction indicated by r by a certain angle so that the blocking portion 151e is opposed to the urging portion 1533, and at this time, the toothed portion 151b of the counting member 151 is not yet engaged with the intermediate gear 16; when the developing cartridge 10 is mounted to the drum assembly 20 again, under the action of the first side 21 of the drum assembly, the abutting portion 1532 drives the force application portion 1533 to move into the second through hole 132 in a direction substantially parallel to the vertical direction of the developing cartridge, the force application portion 1533 applies a restoring force to the blocking portion 151e, the counting member 151 continues to rotate by a certain angle in the direction indicated by r, at this time, the toothed portion 151b of the counting member 151 is engaged with the intermediate gear 16, and once the power receiving member 14 starts to rotate, the counting member 151 starts to rotate in the direction released by r under the driving of the intermediate gear 16, so that the counting is completed.
As described above, the reset operation lever 153 is provided in the third through hole 134 of the cap 13, and preferably, the reset operation lever 153 is formed integrally with the cap 13, and the same material is used for both, and in general, the cantilever-shaped reset operation lever 153 made of the material of the cap 13 can generate a certain amount of elastic deformation, but compared with an elastic member such as a spring, a tension spring, etc., the amount of elastic deformation generated by the cantilever-shaped reset operation lever 153 according to the present invention is small, and in order to overcome this defect of the cantilever-shaped reset operation lever 153, the protruding height for the blocking portion 151e combined therewith is set to be higher, and even if the amount of elastic deformation of the reset operation lever 153 is small, a predetermined operation can be completed in cooperation with the blocking portion 151e, and conversely, if the protruding height of the blocking portion 151e is insufficient, the movement of the cantilever-shaped reset operation lever 153 will not trigger the movement of the blocking portion 151e, and at this time, the reset operation lever 153 can be newly designed, it is common to change the material of the base portion 1531, so that the base portion 1531 can generate a larger elastic deformation, obviously, when the material of the base portion 1531 is different from that of the end cap 13, the end cap 13 and the reset action rod 153 are integrally formed, which cannot be realized, and the whole structure of the reset action rod 153 is complicated, which is not favorable for reducing the whole cost of the process cartridge.
According to the developing cartridge 10 and the processing cartridge provided by the invention, when the developer in the developing cartridge 10 is completely consumed and taken out, after a terminal user adds new development and installs the developing cartridge 10 to office equipment such as a printer or a copier again, the counting element 151 in the developing cartridge 10 can be automatically reset, the counting element 151 does not need to be manually reset by the terminal user, the use experience of the terminal user is improved, the terminal user is more willing to achieve the purpose of reusing the developing cartridge 10 by supplementing the new developer to the developing cartridge 10, and the purpose of utilizing the developing cartridge 10 to the maximum extent is achieved.
