The card-operated copying machine includes (a) key checking cards assigned respectively to the sections, (b) a processor for issuing a signal capable of copying operation, the processor having a random-access memory for storing total copy counts respectively for the sections with flags indicative of permission and inhibition of copying operation, (c) a copy count display for reading the data stored in the random-access memory and displaying the total copy count for each section, and (d) an inhibition card recording thereon information for setting the flags to an inhibition state. The copying operation is permitted and inhibited in response to the flag conditions.
