PURPOSE:To save trouble of an operator, and to facilitate operation, by providing means for a copy instruction signal, and means for detecting occurrence of trouble and inhibiting transmission of a signal from the storage, and transmitting the signal after restoration of the trouble. CONSTITUTION:A copy operation signal G is provided from the output terminal O1 of a timing control circuit 10 to a processing circuit and a reset signal producing circuit 6, and the output B of the circuit 6 is sent to the reset terminal of an FF circuit 3. A trouble processing signal D is provided from the output terminal O2 of a control circuit (timing control circuit) 10 to the trouble processing circuit and an inverter circuit 5, and the output E of the inverter circuit is fed to an AND circuit 4. The output M of a reset switch circuit 2 is fed to the input terminal T2 of the circuit 10, and the output of a trouble detection signal producing circuit 7 is provided to the input terminals T3-T5 of the circuit 10, thus permitting operation to be made easy. |
