ABSTRACT:
A photocopying machine wherein a reflected light pattern is projected along an optical path and onto a photoreceptor surface by scanning a document with an illumination source and reflecting mirror arrangement. Thus, a latent electrostatic image remains on the photoreceptor in a predetermined area thereof. The present invention is characterized by the provision of a multi-facetted reflector built into a platen cover such that it overlies the document from which the light image is reflected when the platen cover is closed. Light rays impinge upon those facets of the reflector which extend beyond the edges of the document and are reflected along the optical path to thereby discharge the photoreceptor adjacent said predetermined area to thereby prevent subsequent development thereof.
