AI Technical Summary

Technical Problem

The existing processing cartridges have large-sized and high-precision drive gears for the developing rollers, which increases the difficulty of production. In addition, the meshing structure of the drive force output component is complex, which affects the load and production efficiency of the imaging equipment.

Method used

The drive force output component has first and second drive force output parts arranged coaxially. The action component of the combined action assembly meshes with the second drive force output part. The extension and retraction of the drive force output component is realized through linear or curvilinear motion, which reduces the rotation space of the action component and simplifies the meshing structure.

Benefits of technology

It reduces the space occupied by the active components, lowers the load on the imaging equipment, simplifies the production process, and improves the reliability of the drive force transmission and the stability of the processing box.

Abstract

The utility model provides a process cartridge detachably installed to an imaging device, the imaging device comprises a driving force output member having a retraction state and an extension state, before the process cartridge is installed to the imaging device, the driving force output member is in the retraction state, when the process cartridge is used for imaging, the driving force output member is converted from the retraction state to the extension state, and the driving force output member is in the extension state. The driving force output piece transmits driving force to the processing box; the processing box comprises a developing box, the developing box comprises an acting assembly with a first state and a second state which are different in position, and under the condition that a first driving force output part and a driving force receiving part are disengaged, when a driving force output part starts to rotate from a static state, the acting assembly forces the driving force output part to be converted from a retracted state to an extended state, in this way, the space needed when the acting piece moves can be reduced, and then the space occupied by the acting assembly is reduced.
