Unit for screening photosensitive medium and electrophotographic image forming apparatus having the same

摘要

A unit is provided to screen a photosensitive medium (114) and an electrophotographic image forming apparatus (100) having the same. The unit for screening a photosensitive medium includes a shutter (120) elastically biased in a direction in which the photosensitive medium is screened. A first link (130), which is capable of making a straight reciprocating motion in a first direction and has a pusher (131) pressing and pushing the shutter to expose the photosensitive medium. A second link (140), which is connected to the first link and is capable of making a straight reciprocating motion in a second direction not parallel to the first direction. When a door (102) of the electrophotographic image forming apparatus is closed, the second link moves so that the first link moves in a direction in which the photosensitive medium is exposed.
