Abstract

PURPOSE: To make the device adaptable to high-speed copying machines by specifying the moving speeds and directions of image side scanning mirrors and lens.
CONSTITUTION: In the case of exposing the image light of an original surface 19 to a photosensitive drum 15 by way of a lens 16 and image side scanning mirrors 17, 18, the image side scanning mirrors 17, 18 are moved integrally in the v2 direction at a speed of 1/4V0 and the lens 16 is moved in the v1 direction opposite from the moving direction of the image side scanning mirrors 17, 18 at a speed of 1/4V0 where the peripheral speed of the photosensitive drum 15 is let V0. Thereby, the scanning is apportioned to the both of the lens 16 and the image side scanning mirrors 17, 18, the respective absolute speeds and moving amounts are reduced by half and the high-speed copying is made possible.
