A card-operated copying machine allows copying operation in response to insertion, one at a time, of key checking cards (CA) for supervising copy counts for a plurality of sections. The card-operated copying machine includes (a) key checking cards (CA) assigned respectively to the sections, (b) a processor (100) for issuing a signal capable of copying operation, the processor (100) having a random-access memory (RAM2) for storing total copy counts respectively for the sections with flags indicative of permission and inhibition of copying operation, (c) a copy count display (56) for reading the data stored in the random-access memory (RAM2) and displaying the total copy count for each section, and (d) a master checking card (CB1) for processing a plurality of supervising items. A switch (81) is operated to select the supervising Items and the processor is responsive to the master checking card to process a supervising item selected by the switch.
