Title: Exposure device
Inventor: YASUDA KAZUO
IPC: G03G15/04
Filed: 1980-12-17
Abstract: PURPOSE:To prevent the degradation in the performance of a photographic receptor owing to heat generation of lamps by using non-linear light sources as  light sources for applying full surface exposure to the receptor, and applying  the light from said light sources via a mirror to the receptor. CONSTITUTION:An optical system for exposure is enclosed by a cover 4 for optical and dustproof purposes, and has a slit 5 of a rectangular strip shape in proximity to the circumferential surface of a drum 1 to limit an imaging range. Light sources 6 are two pieces of non-linear tungsten lamps, which are disposed symmetrically to the optical axis on the outside of the optical path from a projecting lens 2. The lamps 6 are lighted only at a certain time before an electrostatic charging process and at the time of erasing the electric charge in a non- image region. The light from the lamps 6 reflects on a mirror 3 for exposure and is irradiated onto the circumferential surface 1a of a photosensitive drum 1. Thereby, the sticking of the toner floating in the machine on the lamp surfaces during copying is obviated, that is, the degradation in the performance of the  electrophotographic receptor by the heat generation of the lamps is prevented.
