Abstract
PURPOSE: To increase te copying speed by turning the reflecting mirror of a mirror lens by 180 degrees about the optical axis of the rear lens for the forward and backward scanning opreations so that an erect image mdy be focused on the surface of a photosensitive element for the forward and backward scanning operations.
CONSTITUTION: A plane mirror 2 follows another plane mirror 1 at a half speed of the latter to move in the directions of arrows A and B in synchronism with the movements of a photosensitive element 8 so that the image of an original may be focused upon the surface of the photosensitive element 8 through a mirror lens 3 having its optical axes intersecting at a right angle. The morror lens 3 is composed of front and rear lenses 3f and 3b having their optical axes intersecting at a right angle, and a reflecting mirror 4 for reflecting the light flux from the front lens 3f to the rear lens 3b. By turning the reflecting mirror 4 by 180 degrees about the optical axis of the front lens for the forward and backward scanning oprations, the erect image of the original can be foxused upon the surface of the element 8 not only during the forward scanning operation but also during the backward scanning operation.
