Abstract: A color image reproduction apparatus capable of producing a polychromatic reproduction of a color original is disclosed. The apparatus includes a light scanner for scanning the color original to be reproduced to thereby form a light image. A prism or a plurality of color filters are arranged for color-separating the light image into red, green and blue light images and a memory is provided for memorizing those color-separated light images. A plurality of marking units are arranged around a transfer drum carrying a copy paper thereon and cyan, magenta and yellow toner images are formed by the respective marking units and toner images are transferred onto the copy paper in substantially perfect registration. The drive timing of each marking unit in response to conveying timing of the copy paper is controlled by a system controller.

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.
