Abstract

A document drum and a transparent drum are mounted on a common shaft. The two drums are coaxial with each other and with the shaft. An optical system is provided for forming an image of a slit-like rectangular area of a document mounted on the external surface of the document drum onto a similar slit-like imaging area on the imaging drum. The optical system comprises a first mirror for reflecting light rays from the document drum to a lens, and second and third mirrors for reflecting light rays from the lens through the transparent drum. The optical axis of the lens is tilted relative to the light paths of the first mirror and the second mirror so that the light rays can be directed around the shaft.
