A belt tension mechanism includes a tension roller disposed on a side of a photoconductive belt for pressing the photoconductive belt, a first elastic component connected to the tension roller for providing the elastic force to the tension roller, and a releasing device disposed on the other side of the photoconductive belt. The releasing device includes a actuating component for moving in a first direction and separating from the tension roller when being electrified so that the first elastic component can drive the tension roller to a position where the tension roller can press the photoconductive belt, and a second elastic component connected to the actuating component for driving the actuating component to a second direction opposite to the first direction when the actuating component is not electrified so that the actuating component can drive the tension roller to a position where the tension roller cannot press the photoconductive belt.

Belt tension mechanism of an image forming device

The present invention is directed to a shutter system for electrophotographic machines that effectively reduces the impact of ambient light on the photoreceptor, or image-bearing member. The shutter system of the present invention utilizes a shutter member that substantially covers the cartridge chamber when in a closed position. Preferably, the shutter member is disposed at the opening of the cartridge chamber. The shutter member is held in place by one or more support brackets and is biased to the closed position by one or more springs.
