The resetting process of the detected unit 4 according to the present invention will be described in detail below with reference to fig. 13 to 15. In order for the detected unit 4 to be detected again by the detecting unit in the image forming apparatus, it is necessary to reset the detected unit 4, wherein the resetting process of the detected unit 4 includes: applying a force to the detecting member 43 in the axial direction of the detecting member 43, forcing the detecting member 43 to move away from the housing 1, at which time the stopper post 432 of the detecting member 43 enters the groove 444 of the slider 441; an external force is applied to the detection member 43 to rotate the detection member 43 in the M direction, so that the stopper post 432 located in the groove 444 abuts the first stopper wall 445 and the stopper 447. Continuing to rotate the detecting member 43 in the M direction, the detecting gear 42 is engaged with the transmitting gear 3 by the urging of the limit post 432 to follow the rotation, and at this time, the transmitting gear 3 is kept stationary by the force of the engagement between the detecting gear 42 and the transmitting gear 3, and the force is larger than the force of elastically deforming the elastic arm 4431 of the hooking portion 443, so that the elastic arm 4431 of the hooking portion 443 is deformed, the barb 4432 is disengaged from the gear teeth of the currently engaged internal cam 421 and engaged with the next gear tooth of the internal cam 421, and when the detecting member 43 drives the slider 441 to continue to rotate, the detecting member 43 drives the slider 441 to rotate relative to the detecting gear 42 by the sequential engagement and disengagement of the barb 4432 and the gear teeth of the internal cam 421, and when the guide post 431 of the detecting member 43 abuts against the initial limit portion 414 and the positioning portion 434 of the detecting member 43 and the positioning boss 417 of the protective cover 41 abut against each other, the detecting member 43 is reset to the initial position, and the reset of the detected member 43 is stopped, and the reset of the detected unit 4 can be completed. The detection gear 42 is kept not to rotate, the detection member 43 is rotated and reset, the detected unit 4 of the developing box can be reset through simple operation, the production cost is reduced, the protecting cover 41 is not required to be removed in the resetting process, the operation of a terminal user is facilitated, and the service life of the developing box is prolonged.
It should be noted that, as shown in fig. 6, the distance between the surface of the initial limiting portion 414 and the casing 1 is larger than the distance between the plane 412 and the casing 1, so that the detection member 43 can be blocked from entering the end position from the initial limiting portion 414 in the opposite direction of the detected rotation direction M, resulting in malfunction of the detected unit 4, and the developing cartridge cannot be detected. Since the detection member 43 needs to go beyond the initial limit portion 414 from the end position to reach the initial position when being reset, the guide post 431 of the detection member 43 interferes with the initial limit portion 414 in the process of going beyond the initial limit portion 414, when the detection member 43 interferes with the initial limit portion 414, a predetermined external force is continuously applied to the detection member 43, so that displacement of the detection member 43 away from the housing 1 in the axial direction jumps beyond the initial limit portion 414, and after going beyond the initial limit portion 414, the detection member 43 is displaced toward the housing 1 in the axial direction to reach the initial position.
The detected unit of the developing cartridge of this embodiment is provided with a reset member, the reset member is disposed between the detection gear and the detection member, the detection member can be in contact with the detection unit and detected by the detection unit, the detection gear can receive the driving force transmitted by the driving force receiving member and drive the detection member to rotate through the reset member, and the detection member can drive the reset member to rotate relative to the detection gear. The reset member is utilized to realize the counting function of the detected unit, the detected unit of the developing box is reset through simple operation, the production cost is reduced, the protecting cover is not required to be removed in the reset process, the operation of a terminal user is facilitated, and the service life of the developing box is prolonged.
As shown in fig. 16, on the basis of the above-mentioned developing cartridge, the present invention also provides a reset method of a developing cartridge detected unit, specifically, the developing cartridge detected unit includes a detecting gear, a detecting member and a reset member, the detecting member can reach a final position from an initial position to complete detection, the detecting member can drive the reset member to rotate relative to the detecting gear, the developing cartridge is provided with a limit portion for preventing the detecting member from reaching the initial position from the final position, the reset method of the developing cartridge detected unit is used for making the detecting member reach the initial position from the final position, the reset method of the developing cartridge detected unit includes:
step A, applying an external force to the detection member to enable the detection member to move to a first position along the axial direction;
and B, rotating the detection member to enable the detection member to drive the reset member to rotate relative to the detection gear, so that the detection member passes through the limit part from the first position to reach the initial position.
In this embodiment, in the axial direction of the detecting member, the distance between the detecting member and the housing at the end position is smaller than the distance between the detecting member and the housing at the initial position, and a stopper is formed between the end position and the initial position, which stopper blocks the detecting member from reaching the initial position from the end position in the detected rotational direction, and the detecting member is moved to the second position in the axial direction by applying an external force to the detecting member, wherein the distance between the detecting member and the housing at the second position is equal to the distance between the detecting member and the housing at the initial position, and at this time, the detecting member is rotated, so that the detecting member drives the reset member to rotate relative to the detecting gear, and the detecting member is rotated beyond the stopper to the initial position in a state where the detecting gear is kept from rotating, thereby completing the reset of the detecting member, that is, the reset of the detected unit of the developing cartridge.
Further, in step B, the detection member is interference fit with the limit portion and jumps beyond the limit portion. In this embodiment, the height of the limiting portion relative to the housing is slightly greater than the distance between the detecting member and the housing at the initial position, so that the detecting member interferes with the limiting portion in the process of rotating from the first position to the initial position, when the detecting member interferes with the limiting portion, a predetermined external force is continuously applied to the detecting member, so that displacement of the detecting member away from the housing in the axial direction jumps over the limiting portion, and after the displacement of the detecting member over the limiting portion, the detecting member is displaced toward the housing in the axial direction to reach the initial position. Wherein the detecting member rotates in the same direction of the detected rotation direction beyond the limit portion. The distance from the end position to the initial position of the detection member is short, so that the detection member can be quickly reset, the operation steps can be simplified, and the resetting operation difficulty is reduced.
