Problems solved by technology

In the prior art, in order to prevent the power receiving member 0212 whose third part is spherical from protruding from the flange cylinder 0210, as image 3 As shown, a barb 02107 is provided on the protrusion 02105 near the opening of the flange cylinder, and along the radial direction of the flange cylinder, the distance between the opposite barbs is smaller than the third part The diameter of 0212c, however, if the distance is too small, although it can effectively prevent the power receiving part from falling off, it will cause the third part 0212c of the power receiving part to not be easily pressed into the flange cavity; if the distance is too large , it will not be able to effectively prevent the power receiving part from falling off, therefore, the distance must be precisely controlled, that is, the size of the barb part 02107

Embodiment 1

[0079] Figure 11is a block diagram of the power supply control circuit in this embodiment. The power supply control circuit 5 includes a main power supply 50, a first switch circuit 51, a second switch circuit 52, a voltage boost circuit 53, a voltage drop circuit 54, a trigger device 55, a control circuit 56 and a forward / reverse drive circuit 57, the first The input end of the switch circuit 51 and the input end of the second switch circuit 52 are all connected with the main power supply 50; the output end of the first switch circuit 51 is connected with the input end of the booster circuit 53; the output end of the second switch circuit 52 is connected with the The input end of the control circuit 56 is connected; the input end of the step-down circuit 54 is connected with the output end of the booster circuit 53, and its output end is connected with the input end of the second switch circuit 52; the input end of the control circuit 56 is also connected with the trigger de...

Embodiment 2

[0082] Figure 12 is a block diagram of the power supply control circuit in this embodiment. In order to prevent when the battery power in the first embodiment is exhausted, Figure 11 The positive / reverse driving circuit 37 in the motor cannot work, and eventually the disadvantageous situation that the power receiving member 212 cannot be pulled back occurs. Compared with the first embodiment, the backup power supply 58 and the backup power switching circuit 59 are added in this embodiment.

[0083] Such as Figure 12 As shown, the main power supply 50 and the backup power supply 58 are connected through the backup power switching circuit 59, the backup power switching circuit 59 is also connected to the boost circuit 53, and the backup power supply 58 is connected to the forward / reverse drive circuit 57. In this implementation In an example, the voltage output by the backup power supply 58 is not only used to drive the forward / reverse drive circuit 57 to work, but also to ...

Abstract

The invention relates to a processing cartridge which comprises a processing cartridge shell and a rotating part mounted in the shell, wherein the rotating part comprises a power receiving mechanism mounted at a longitudinal tail end of the rotating part and a force application mechanism connected with the power receiving mechanism; the force application mechanism comprises a power supply control circuit with a trigger device; the trigger device goes beyond the processing cartridge shell; when the power receiving mechanism is connected with a light-sensitive cylinder positioned in the processing cartridge through a flange cylinder and transfers power, barb parts do not need to be arranged at a position, which is close to an opening of the flange cylinder, of a protruding part of the flange cylinder, and the distance between the barb parts does not need to be accurately controlled. Therefore, the requirement on the manufacturing precision of the power transmission device in the processing cartridge is low.

Description

technical field [0001] The invention relates to the field of electrophotographic imaging, in particular to a process box detachably installed in an electrophotographic imaging device and a corresponding electrophotographic imaging device. Background technique [0002] Electrophotographic imaging is the process of using the photosensitivity of the photosensitive member to charge and expose the photosensitive member, and then sequentially develop, transfer, fix and clean; the process box is a consumable in the process of electrophotographic imaging, including multiple The rotating member, in addition to the above-mentioned cylindrical photosensitive member, also includes components for charging it, such as a cylindrical charging roller, and developing components, such as a cylindrical developing roller or magnetic roller, in electrophotography Both are constantly rotating during the imaging process, therefore, during the electrophotographic imaging process, rotational power mu...
