PROBLEM TO BE SOLVED: To prevent image recording at the time of receiving failure. SOLUTION: A receiving detecting circuit 26 detects the level of receiving carrier of a signal that is sent from a spread spectrum receiving circuit 12. A recording part control circuit 18 compares an output of the circuit 26 with a threshold, detects whether or not receiving is successful, and instructs a recording unit 14 to stop its recording operation when the failure of receiving continues for a fixed time. When the receiving is recovered, the circuit 18 frees the stop of the recording operation of the unit 14 and makes the unit 14 to carry out the recording operation. |
