Abstract
An optical system for directing a light image of a scanned original to a charged photosensitive surface of an electrophotographic copying apparatus, includes an imaging lens located between the original and the photosensitive surface. The optical axis of the imaging lens is directed normally to the original and the lens is movable in a direction substantially parallel to the original during scanning of the original. At least one mirror is disposed to receive the imaging rays from the imaging lens to reflect them onto the photosensitive surface, and each mirror is moved synchronously in a different direction from the lens to maintain the rays reflected from the original at a proper position during scanning.
