If manual reception is set by the operation unit 9, even if a bell signal arrives, the CML relay 3 remains as it is, so the bell of the telephone 2 continues to ring. When the telephone 2 is taken off-hook and answered, the tone decoder 7 is set to 1100 Hz. When a CNG signal (1100 Hz) from the other party's facsimile arrives from the telephone line 1, it is detected by the tone decoder 7 and output to the control section 8. The control section 8 switches the CML relay 3 to the communication section 5 side and performs facsimile communication.

First, in step s1, it is determined whether the transmitter/receiver of the telephone 2 is in an off-hook state or not according to a detection signal from the hook state detector 4. If it is in an on-hook state, the detector 6 outputs a 16 Hz ringing signal in step s2. is detected. In the case of detecting a 16Hz ringing signal, it is determined in step s3 whether the signal has been detected a predetermined number of times (for example, 3 or 4 times), and when the 16Hz ringing signal is detected a predetermined number of times, the CML relay is activated in step s7. 3 to communication department 5
automatically performs facsimile reception processing. If the predetermined number of 16 Hz calling signals are not detected, the process proceeds to step s4, where it is determined whether or not a signal from the tone decoder 7 (1300 Hz signal detected) is detected. Then, when a signal is detected in step s4 (a signal of 1300 Hz is detected), the process proceeds to step s7, where the CML relay 3 is switched to the communication section 5 and facsimile reception processing is automatically performed.
