A card-operated copying machine allows copying operation in response to insertion of one, at a time, of key checking cards for supervising copy counts for a plurality of sections. 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.
A card-operated copying machine comprising a processor responsive to information recorded on key checking cards assigned respectively to a plurality of sections for issuing signals capable of copying operation, memory means for storing total copy counts for the respective sections, display means for displaying the total copy count for each of said sections, said memory means having a flag indicative of permission and inhibition of copying operation for each of said sections, and an inhibition card recording thereon flag inhibition information for setting said flag to an inhibition state, said processor being capable of issuing a signal indicative of inhibition of copying operation in response to the key checking card for a section corresponding to a flag in the inhibition state.
A card-operated copying machine comprising a processor responsive to information recorded on key checking cards assigned respectively to a plurality of sections for issuing signals capable of copying operation, memory means for storing total copy counts for the respective sections, display means for displaying the total copy count for each of said sections, a master checking card for processing a plurality of supervising items, and a switch for selecting the supervising items, said processor being responsive to said master checking card for processing a supervising item selected by said switch.
