PURPOSE:To obtain comparatively easily and at low cost the functon as an output printer of a digital signal by constituting an erase lamp of the collection of light emitting body consisting of small parts. CONSTITUTION:A photosensitive body is electrified uniformly, a light from a main exposure light source is irradiated to a copying original on an original platen, its reflected light is to the electrified photosensitive body and exposed, an electrostatic latent image of an original image carried on the photosenitive body is visualized, and thereafter, also it is transferred to a recording paper, and an usual copy mode of an original for obtaining a recording picture operated. In addition to each member placed around a photosensitive drum, an erase lamp 9 which is extended in the axial direction of the photosensitive drum 1 and constituted of the collection body of a small light emitting part is placed between an electrifying charger 3 and an exposing part 4. The erase lamp 9 is formed by arranging many light emitting segments 9a being a small light emitting part, by (n) rows (n>=1), and desirably, that formed by arranging two rows - about 20 rows is used in the axial direction of the photosensitive drum 1. Its array density is six - eight pieces/mm. in the axial direction. |
