PURPOSE:To prevent wasteful copying with simple operations by controlling the execution of copying cycles by the copying start command according to the use frequencies of copying materials. CONSTITUTION:The set output of an FF 102 by the operation signal 101 of copy button becomes a copying start command and is applied to the control circuit of the copying machine via the AND gate 107 which is opened by a mounting signal 103 when a cassette containing copying materials of a high use frequency is mounted. Copying cycle is then executed at the same instant of operating the copy button when the copying paper of a high use frequency is used. On the other hand, the set output of an FF 106 which becomes copying start command by the operation signal 105 of an assignment key for a cassette of a lower frequency size is applied to the copying controller by way of an AND gate 108 which is opened by a low use frequency cassette mounting signal 104 and an AND gate 109 which is opened by the set output of the FF 1-2 and the copying start command state is set unless there is assignment by the key of the low use frequency cassette, thus wasteful copying is prevented by the simple operations. |
