Abstract
PURPOSE: To enhance copying efficiency without complicating a device by providing 2 scanners and by enabling exposure of a photoreceptor even during movement of movable parts of optical systems.
CONSTITUTION: First plane mirror 1 is movalby arranged along the surface of original 0, and in forward scanning the original surface is scanned by moving from the position of a full line to position 1a an alternate long the short dash line. Second plane mirror 2 follows mirror 1 at a moving speed of 1/2 of that of mirror 1 when mirror 1 moves, and mirror 2 moves from the position of a full line to position 2a of an alternate long and short dash line. A light flux reflected from original 0 is reflected by mirrors 1 and 2, falls on through lens 3, further reflected by plane mirrors 4 and 5, and forms the image on surface 50 of photoreceptor 9. In backward scanning, the light flux reflected from original 0 is reflected by third plane mirror 11 combined with mirror 1 in a roof shape, further reflected fourth plane mirror 22 moving at a speed of that of mirror 11, falls on through lens 3, reflected by reflective faces 44 and 55 of prism 45, further reflected by plane mirrors 66 and 77, and forms the image on circumferential surface 770 of photoreceptor 9.
