Abstract

PURPOSE:To make possible displaying of numbers of copied sheet of reiterative copying paper even when the originals are put still in the specific position by resetting paper feed counters according to the specified plural switch operations. CONSTITUTION:The pulses at every feeding of copying paper are applied to an automatic shut-off signal generator AS and when the next feed pulse is not generated for longer than the specified time, a generator AS generates a shut-off signal. On the other hand, the pulse which an automatic pring signal generator AP generates at every insertion of the originals at every push of the pushbutton of the copying machine by a switch SW2 is applied together with the clear signal and the shut-off signal output by the generator AS to an OR circuit OR2 via AND gate AND1 which opens together with the closing of switches SW3. Hence, counters C1-C3 are cleared by any of these signals and the number of copying sheets may be displayed in an ordinary copying sheet number display device at the reiterative copying.
