Abstract

PURPOSE:To make copying image of good quality by making use of the change in the relative position relation of reflecting means even for the correct ratio of approach-run distance with respect to each magnification. CONSTITUTION:The 1st and the 2nd mirrors 5, 6 are the movable mirrors which scan the original 2. Both mirrors 5, 6 move in the same direction at a speed ratio of 1:1/2 and parallel to the original platen to maintain the optical path length to be set at the specified length constant with respect to the magnification selected between a lens 7 and original 2. At the time when the mirrors 5, 6 move upper leftward, they scan the original 2, at which time the original images are slit-exposed to an electrophotographic receptor 1. By this exposure, the electrostatic images are formed on the photoreceptor 1 and these electrostatic images are developed. The developed images are transferred and fixed.
