ABSTRACT:
An electrophotographic copying apparatus wherein the original is placed face down onto a stationary transparent holder which is located above a reciprocating carriage for a lens element. The latter images the original onto a light receiving surface which travels along a straight path while the carriage moves in the same direction as the light receiving surface. The carriage can be moved by an eccentric drive, by a wiper which is attached to an endless belt or chain, or by a cam and follower assembly. The original is illuminated by flash lamps which are fired automatically while the carriage moves in the same direction as the light receiving surface.
