Power transfer device, photosensitive element and processing cartridge

Abstract

The invention relates to a power transfer device, and a photosensitive element and processing cartridge having the power transfer device. The power transfer device comprises a flange having a rotation axis L1, a flange bracket, a power receiving part and a power transfer part mounted in the flange, and a moving part, wherein the flange bracket is used for supporting the flange; the power transfer part is mounted in the power receiving part; the power receiving part is penetrated through the moving part; and the moving part is mounted between the flange and the flange bracket. When the power transfer device and a power output device are connected or disconnected, the acting force of a printer door is not needed, thereby effectively ensuring that the photosensitive element or processing cartridge provided with the power transfer device can be widely used.

Description

technical field [0001] The invention relates to the field of electrophotographic imaging, in particular to a power transmission device, a photosensitive element and a process box with the power transmission device. Background technique [0002] A printer is a type of electrophotographic imaging device, and a process cartridge detachably installed in the printer is a consumable therein. The process cartridge works by receiving driving force from the printer. In order to obtain the driving force required for the process cartridge to work, Generally, a power output device is arranged in the printer, and a power transmission device is arranged in the process box. After the process box is loaded into the printer, the power transmission device is combined with the power output device to receive and transmit driving force; When it is disassembled, the power transmission device is disengaged from the power output device. [0003] figure 1 is a schematic diagram of the overall stru...

Problems solved by technology

[0006] However, after the process cartridge C is loaded into the printer, the end of the pressing rod 13 connected to the spring 18 is a free end suspended outside, and the external force F comes from the printer door, that is to say, the power receiving port 12 Extending out requires the help of the printer door. It must be ensured that the printer door is closed along the Y direction and can touch the pressing rod 13, and the printer door can continuously apply force to the pressing rod 13. When the printer door is loose, Even if the printer door can touch the pressing rod 13, it cannot provide continuous active force to the pressing rod 13, and the stretching of the power receiving port 12 will not be realized; when the closing direction of the printer door is perpendicular to the X direction and the Y direction During the -Z direction, the printer cover door will not be able to touch the pressing rod 13, therefore, the power receiving port 12 will not stretch out, and the scope of application of the process box provided with the power receiving port 12, pressing rod 13 and spring 18 is limited. extremely restrictive
