Abstract

PURPOSE:To control the estimate required for the number of copying papers of copies by restricting the number of sheets with an addition type counter of freely detachable for each user unit of a copying machine. CONSTITUTION:When a counter 1 is mounted to a mounting part 4, content of a memory 6 and content of the counter 1 are compared by a coparator 9, if a numerical value of the counter is smaller than that of the memory an output signal is issued, copying by the stated number of sheets is performed at a copying part 10 and a pulse from a pulse generator 11 indicates with addition a numerical value of the counter 1. Therefore the overall number of sheets copied is always indicated on the counter 1. Further, when the number of sheets of this display and the number of setting coincide, from the comparator 9 a coincidence signal is outputted and copying at the copying part 10 stops. When copying over that is required, an alteration of memory contents is permitted. Accordingly, copying more than set previously at each user unit is prohibited and control of estimate is performed exactly.
