Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a facsimile machine incorporating a so-called cordless telephone.

2. Description of the Related Art Conventionally, in order to effectively utilize one telephone line, there has been a facsimile machine in which a facsimile machine and a telephone are integrally configured and selectively connected to one telephone line. There are also facsimile machines that can be connected to commercially available telephones in addition to the built-in telephone, and facsimile machines that have a built-in or connected cordless telephone in addition to the built-in telephone have also been developed.

Such a facsimile device with a cordless telephone can not only send and receive facsimiles and make calls to outside lines using the telephone, but also make calls between built-in telephones, so-called extension calls.

Problems to be Solved by the Invention In the above-mentioned facsimile machine with a cordless telephone, when making an internal call, that is, a call between the handset of the cordless telephone and a telephone connected to the main body of the facsimile machine, the telephone line is connected to the telephone and the facsimile machine. It is in a state where it is not connected to either side of the equipment, the so-called open state, and even if it detects an incoming signal from the exchange, it does not have a means to notify the caller on the extension, so it should have the highest priority. I had no choice but to ignore extremely important outside calls.

SUMMARY OF THE INVENTION An object of the present invention is to provide a facsimile apparatus that can notify an extension caller of the detection of an incoming call signal from an exchange during a so-called extension call.

Means for Solving the Problems The present invention comprises: a facsimile communication unit connected to a telephone line and configured to send and receive facsimiles; first and second telephone units configured to make telephone calls; and the first and second telephone units connected to the telephone line. A connecting means for connecting to a line or connecting between the first and second telephone parts, an incoming signal detecting means for detecting an incoming signal from an exchange, and an operating means driven in a predetermined driving state, The facsimile apparatus is characterized in that when an incoming call signal is detected while the first and second telephone parts are connected, the actuating means is driven.

According to the present invention, when an incoming call signal is detected by the incoming signal detecting unit while the first and second telephone units are connected by the connecting unit and a so-called extension call is being carried out, the actuating unit operates. It is driven in a predetermined driving state. This allows the extension station to know that there is an incoming external call, that is, a call from the calling station.

As a result, the extension caller can terminate the extension call, connect the first and second telephone parts to the telephone edge by means of the connecting means, and receive a call from the outside line, that is, communication from the calling station. Furthermore, if the communication from the calling party is by facsimile, it can be received by the facsimile communication unit. This allows you to make so-called extension calls without ignoring outside R calls, which should have the highest priority.
A facsimile machine can be used effectively.
