Abstract
A copy machine having a plane stationary platen for holding an original and having also capability in facsimile transmitter and receiver is disclosed. A first scanning mirror is driven in parallel with the platen surface at the same speed as a photosensitive medium. A second scanning mirror is driven synchronously at half the speed of the first scanning mirror and in the same direction. An in-mirror lens comprises a reflex mirror and a spherical lens system and a fourth fixed reflex mirror is located on the same side of both scanning mirrors vis-a-vis the in-mirror lens. It serves to reflect an image forming beam from the in-mirror lens forwards the photosensitive medium. The facsimile function uses a beam deflector comprising an in-mirror lens, a rotary polygonal mirror and a polygonal mirror driving mechanism. This additional system is disposed at a position optically equivalent to the nodal point of half of the in-mirror lens. An incident optical system directs a laser beam from a source toward the beam deflector. The beam deflected by the beam deflector is selectively directed toward either the platen surface or the photosensitive medium surface.
