LIGHT EMISSION DEVICE ARRAY FITTING STRUCTURE OF ELECTROPHOTOGRAPHIC APPARATUS

摘要

A light emission device array fitting structure of an electrophotographic apparatus for forming an electrostatic latent image by exposing a photosensitive drum to light from an array composed of a large number of light emitting diodes, etc. It is intended to keep a stable condition for a long time to expose the photosensitive drum with image-carrying light of high quality. The fitting structure comprises a fixed bracket (31) made of a rigid body fixedly disposed in the electrophotographic apparatus, a rotary bracket (33) made of a rigid body fixed to the light emission device raay (2) and connected rotatably relative to the fixed bracket (31), urging means (37) for urging the light emission device array to the outer peripheral surface of the photosensitive drum (1), and gap retaining means (38) for keeping a gap between the light emission device array (2) and the outer peripheral surface of the photosensitive drum (1) constant, when it is pushed to the outer peripheral surface of the photosensitive drum (1) by the urging force of the urging means (37).
