It is detected whether or not the abnormal state of the printer 31 is an abnormal state in which it is necessary to stop the copying machine. Here, the abnormal state in which the copying machine needs to be temporarily stopped is, for example, a case where the recording sheet is out of paper or the recording sheet is jammed. In such an abnormal state, the abnormal state detection signal is given to the printer processing circuit 42 by the detecting means 51 or the detecting means 52. An abnormal state in which it is not necessary to temporarily stop the copying operation is, for example, the recording paper feeding cassette 3.
For example, the cover body of No. 5 is not fully closed. In such an abnormal state, the abnormal state is detected by the detecting means 53, and a detection signal notifying the abnormal state is given to the printer processing circuit 42. When an abnormal state in which it is necessary to stop the copying operation in step P7, that is, when a recording sheet is jammed, for example, the process proceeds to step P7 and then to step P8 to receive the detection signal from the detection means 52 and the printer processing circuit. An interrupt signal from 42 is given to the copy processing circuit 41. As a result, the copying operation is temporarily stopped. Then, the process proceeds from step P8 to step P9. If it is determined in step P7 that the printer 31 is in an abnormal state and it is not necessary to temporarily stop the copying operation, the process proceeds from step 7 to step P9. At step P9, an abnormal condition such as a paper jam or an open cover is repaired. When the abnormal state is cleared in this way, the process proceeds to step P10, where it is determined whether the processing circuit 42 has output an interrupt signal to the processing circuit 41,
When no interrupt signal is output, the process returns to step P3. When the interrupt signal is being output, step P
11, the return button 54 is pressed to output the return signal of the return button 54 to the copy processing circuit 41.
Then, the process returns to step P3 again.

When the printer 31 is not in an abnormal state at step P6, the process moves to step P12 and the recording paper printed on the tray 34 is discharged. Then, it is judged whether or not the printing operation is completed in step P13, and if it is not completed, the operation returns to step P2 again, and then a series of operations from step P2 to step P13 is repeated to carry out desired printing on the recording paper. Done. And step P14
