PURPOSE:To save waste of time, and to avoid occurrence of trouble, by sending the last copying paper which is not to be copied in making copies with a both side automatic copying machine using a single-side original, to the outlet of a copying paper after the completion of copying on the surface without executing a normal copying cycle to obtain this blank copy. CONSTITUTION:A first sensor for detecting presence of an original G on an original tray 2 and a second sensor 14 for detecting presence of a sheet on a buffer tray 13 send each sheet detection signal to a controller 15. The controller 15 sends signals for operating branch gates 9, 90, etc., when the contents of the signals of the sensors 1, 14 show both the absence of the sheet, changing the cource of the copied paper to deliver it to a paper discharge cource 11A or that 11B. |
