When the G signal is detected and the CNG signal is detected, F is detected.
When the AX reception operation is started and the CNG signal is not detected, it is determined that the telephone is received, and an operation of ringing a bell to call the operator is performed.

Here, the CNG signal is a signal indicating that the calling station is a non-voice terminal, and is a tone signal of 1100 Hz, which is transmitted at intervals of 0.5 second ON and 0.3 second OFF. It is a signal.

In such a method of switching between facsimile reception and telephone reception, a problem occurs when the CNG signal cannot be detected within a short time after the incoming call. That is,
If the CNG signal cannot be detected within a short time after the incoming call, it is necessary to continue the detection of the CNG signal and ring the bell to call the operator.
When the CNG signal is detected after the bell is sounded, the FAX reception is performed despite the bell being sounded, resulting in unnecessary call to the operator.

If the ringing of the bell is delayed in order to avoid this, in the case of telephone reception, the time from when the caller starts calling until the ringing of the receiving side begins to take longer. , It is more likely that the caller hangs up by the time the receiving operator picks up the handset.

An object of the present invention is to provide a fax machine which has both a fax function and a telephone function, in a fax machine.
It is an object of the present invention to provide a facsimile device that can quickly switch between reception and telephone reception.
