Abstract

PURPOSE:To prevent unpleasant noise from being given to a concerned person during extension talking by activating an automatic reception function of a facsimile equipment section after the end of extension talking when a call comes during the extension talking. CONSTITUTION:When an incoming call is detected by an incoming call detection circuit 9, a control circuit 12 drives a bell 10 to inform the presence of the arrival of the call. In this case, the control circuit 12 detects it whether the extension talking state is in operation or not and detects to which of automatic reception and manual reception the mode is set when not in the extension talking. When a call comes during the extension talking state, the control circuit 12 does not implement reception processing till the extension talking is terminated even when the automatic reception mode is set. Thus, it is prevented that a sense of displeasure is given to the person concerned of extension talking due to a digital noise caused by facsimile reception.

First, when an incoming call is detected by the incoming call detection circuit (9),
The control circuit (12) drives the bell (10) to notify that there is an incoming call (steps S-1, S-2). At this time, the control circuit (12) detects whether or not an extension call is being made, and if it is not an extension call state, it detects whether automatic or manual reception is set (setting is done by using the automatic/manual switch key). (steps S-3, 4). If manual reception is set, the operation of the reception key is monitored, and if the operation is detected, the selector switch (7) is switched to the facsimile unit (2) side and facsimile reception is performed (step S-5-6). ). Also, if automatic reception is set, the selector switch (7) is automatically switched to the facsimile unit (2) side after a predetermined number of rings (for example, 5 times) to receive the facsimile. Step S-7, 6).

Note that the number of ringing tones can be detected by counting the pulses, since the incoming call detection circuit (9) is set to output pulses with a width corresponding to the period in which the ringing tone is generated.

When reception starts, driving of the bell (10) is stopped, and when reception ends, the changeover switch (7) is switched to the line connection switch (6) side (steps S-8, 9, 1).
