Abstract

The invention relates to a power transmission device of a printer. The device comprises a photosensitive element, a power reception port within the photosensitive element, a driving head separable from the power reception port, and shrapnels installed between the driving head and the power reception port to transmit power to the photosensitive element circumferentially along the driving head of the printer. Due to the shrapnels between the driving head and the power reception port for transmitting power to the photosensitive element circumferentially along the driving head of the printer, power transmission between the driving head and the power reception port becomes more flexible. Not only is the torque relatively reduced, but also the driving head is more stably engaged with the power reception port, thus providing a solution to the present technical problem that great torque is needed for the printer driving head of a printer power transmission device to drive the power reception port and the problem for realization of stable engagement of a power transmission mechanism.

Description

technical field [0001] The present invention relates to an image forming device, and more particularly to a power transmission device in the image forming device. Background technique [0002] An electrophotographic image forming device such as a laser printer is a device that uses the principle of electrophotography to form an image on an image forming medium such as paper through at least the processes of charging, exposure, development, transfer, and fixing. [0003] In the charging process, through the charging device, the surface of the photosensitive component such as the photosensitive element is charged with a uniform predetermined charge by means of corona discharge; in the exposure process, the surface of the photosensitive element that has been charged with a uniform predetermined charge is selectively exposed. In the exposed place, due to the photosensitive characteristics of the photosensitive element, the resistance drops, so the charge on the exposed place is ...
