ABSTRACT:
A photocopying machine wherein a reflected light pattern is projected along an optical path and on to a photoreceptor surface by moving a document supported on a transport belt past a stationary illumination source and reflecting mirror structure. The light pattern impinges on the photoreceptor in a predetermined area thereof, which is provided with a uniform electrostatic charge capable of being discharged in accordance with the light pattern. The present invention is characterized by the provision of a multi-faceted reflector which is supported to one side of a document carrying belt such that illumination from the source can be reflected along the optical path to thereby discharge the photoreceptor adjacent the area struck by the light pattern.
