ABSTRACT:
A system for feeding originals one by one from a stack of them to the illumination station of a copying machine and finally back to the top of the stack, so as to enable automatic production of sets of correctly sequenced copies of double-sided and/or single-sided originals, comprises a holder for stacking originals, means for removing the bottom original from the holder, a first transport path for transporting the original from the holder to the illumination station via its inlet side with the side of the original that faced downward in the holder in position for copying, means for transporting the original from the exit side of the illumination station into a reversing path and from the reversing path again via the inlet side to the illumination station, and means including at least part of the reversing path and a final transport path for returning the original from the exit side of the illumination station to the holder and placing it in its original orientation on top of the stack.
