Abstract
PURPOSE: To reduce the using space including the occupying space of the apparatus housing and achieve the reduction in exposure time by moving both of original platen and optical mechanism in mutually opposite directions in performing scanning.
CONSTITUTION: The moving direaction of the upper travelling portion of a photoreceptor 8 is made opposite from the moving direction of an original platen 2 and since this direction coincides with the moving direction of the optical mechanism, the upper travelling portion 8A is moved at the speed of the magnitude comprising adding the moving speed of the optical mechanism to the relative speed of the original platen 2 and optical mechanism. Since both of the original platen 2 and optical mechanism are moved in this way, the entire sufrace of the original is scanned and exposure is done by the upper travelling portion 8A to the photoreceptor 8 which is being moved in synchronization, thus the photoreceptor is evenly charged by a charging electrode 10. Thereby, the moving distance of the original platen may be reduced, the occupying area of the entire part may be reduced and the time required for exposure reduced.
