PURPOSE:To obtain a copying system which permits copying within set sheet numbers by putting copying machines mounted with counters into an active state as far as the count values of the counters which are freely attachable and detachable and make down counting are not zero. CONSTITUTION:Counters 1 which are held in respective divisions and are freely attachable and detachable to and from desired copying machines 4a- make down counting from set sheet numbers at every copying and the permissible remaining sheet numbers are displayed in their display parts 2. As far as the count values thereof go zero, the count value read signal transmitting and receiving part 6 of the copying machine 4 mounted with this counter 1 outputs a high level signal and a high level signal for copying permission is applied from the AND circuit 13 of a control part 8 to the copying machine 4, whereby copying is accomplished. Hence, the copying system permitting copying within the set sheet numbers is obtained. |
