Abstract
An electrophotographic copying machine using a roll of sensitive paper in which the original holder for carrying the original reciprocates on the machine case of the electrophotographic copying device. While the original holder is in its backward motion, the original is illuminated so as to subject the electrophotographic-sensitive paper to a slit exposure, and the copy is obtained through subsequent steps of developing and fixing. The reciprocating motion of the original is related to the paper feed so that the paper is cut to the length of the original. An indicator is provided for indicating the size of the roll of sensitive paper in the paper-feeding unit and for indicating the maximum size original capable of being copied.
