<p>PURPOSE:To place copying papers in line at a fixed position in a both-side duplicating machine by providing a stopper for stopping copying papers accumulated on an intermediate tray at a position where the top of the copying papers are extended by a fixed length from the intermediate tray. CONSTITUTION:A copying paper P2 copy-printed on one side is guided by a guide plate 26 to be extended from the top of an intermediate tray 12, and brought in contact with a stopper member 50 to be placed on the intermediate tray 12. When a paper sensor 53 detects the contact of a paper P2, a solenoid is operated to move the stopper member 50 to be pushed to the top of the intermediate tray 12, and the top of the paper P2 is lined up with the top of the intermediate tray 12. After the final paper leaf is accumulated on the intermediate tray 12, when copy-printing on another side is started, the stopper member 50 is retreated from a paper-conveying route by the starting signal, and a pick up roller 27 is brought down to send papers successively into a conveying roller pair 10. This construction permits to line up papers at the top by a simple construction.</p> |
