Abstract
The duplex copying machine according to the present invention is arranged to copy both faces of an original document onto both faces of copy papers in such manner that the front and the reverse surfaces of the original document are copied correspondingly onto those of the copy papers, without inconsistency of the copied surfaces, even when paper jamming is given rise to in the course of the operation under the verso copying mode. Further, the duplex copying machine according to the present invention has such function as to positively classify the copy papers subsequent to the jammed paper into respective proper bins.
