Abstract

A dual imaging scanning system for simultaneously projecting an image of an object onto a photoreceptor drum 1 at two exposure stations 2 and 3. A platen 4 supports an original to be copied. Below the platen there is provided an optical scanning system having a full-rate mirror 5 directing a light image of the original onto two half-ratemirrors 6 and 7. The half-rate mirrors are at right angles to one another and in turn, direct the image to a lens 8. From the lens 8 an image of the document is reflected by mirror 9 onto the photo-receptor at exposure station 2. Simultaneously, the identical image of the document is reflected from mirror 10 to mirrors 12 and 11 and onto the photoreceptor at exposure station 3.
