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.

Exposure system for electrophotographic copying apparatus

A copying machine wherein successive finished sheets issue from an opening in the front wall of the housing in such positions that the printed matter is observable from above. Successive sheets pass below an observation window which is adjacent to the opening so that the quality of printed matter can be observed from above. The sheets are thereupon inverted so that the printed matter faces downwardly, and are stacked on top of each other in a tray having a bottom panel the inner end portion of which constitutes the observation window. The sheets are inverted in a channel having an inlet below the observation window and an outlet above the end of the tray which is remote from the opening.
