Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram for explaining the principle of the present invention. As shown in the figure, when a signal is transmitted from the other party FAX 1, the signal is received by the key telephone system control main unit 3 via the analog exchange 2. The incoming call signal is detected by the 16 Hz incoming call detection circuit 4, and the incoming call is transmitted to the extension telephones 7 and 8 via the centralized control circuit 5 and the data transmission circuit 6. Then, the first extension telephone 7 (extension number 1) or the second extension telephone 8 (extension number 2) having an answering machine support function responds. At the same time responding,
Since the FAX signal detection circuit 10 of the FAX connection adapter 9 (extension number 3) is connected in parallel to the extension telephones 7 and 8, the FAX connection adapter 9 causes the switching relay 18 to pass through the FAX signal detection circuit 10 side. The FAX signal detection waits.

When the line on the receiving side responds in this way, the partner FAX 1 starts transmitting a FAX signal. Then FA
The X signal detection circuit 10 detects the signal and transmits the signal to the serve control circuit 12 via the data transmission circuit 11,
Disconnect the extension telephone 7 or the second extension telephone 8
The line is connected to the stand-alone FAX 13 so that the FAX signal can be received.

As described above, according to the present invention, by providing the FAX signal detection circuit 10 in the FAX connection adapter 9,
The reception of the AX signal is automatically transferred to the standalone FAX 13. In this respect, the first extension telephone 7 or the second extension telephone 8 responds to the signal from the other party's FAX 1,
Smooth fax communication becomes possible as compared with the conventional operation in which a person confirms FAX reception by the signal or verbally, temporarily suspends it, and transfers it to the FAX connection adapter 9. The extension telephone that responds to the signal from the other party's FAX1 is released from the communication line, and a display device such as a liquid crystal display is provided on the extension telephone to notify the responder of this, or the extension telephone is completed. If a method of providing a sound generator is adopted, convenience in use can be achieved.

FIG. 2 and FIG. 3 continuously show the first embodiment, and are block diagrams of operation modes based on the principle configuration diagram shown in FIG. 1 (of the portion corresponding to FIG. 1). The same symbols are attached to the operation displays, and the same applies to the following drawings). As shown in the figure, when the other party's FAX 1 makes a call, a 16 Hz incoming signal is sent from the analog switch 2 on the receiving side. This 16 Hz incoming call signal is detected by the 16 Hz incoming call detection circuit 4 of the key telephone system control main unit 3, and passes through the centralized control circuit 5 and the data transmission circuit 6 to the extension telephone 7 (8).
The incoming call is delivered to.

Then, the extension telephone set 7 (8) passes through the data transmission circuit 14 (15) and the sub control circuit 16 (17).
To send a signal to ringing and answer the line. In this case, if there is a person on the side of the first extension telephone 7, the person responds,
When not present, the second extension telephone 8 responds. When answering, button telephone system control main unit 3
The centralized control circuit 5 stores the response of the extension telephone 7 (8) as data and, at the same time, instructs the FAX connection adapter 9 to detect a FAX signal.
At this time, the switching relay 18 (FIG. 1) faces the FAX signal detection circuit 10 and waits for detection.

Then, the FAX signal detection circuit 10
When the signal is detected, the sub control circuit 12 determines that the incoming call is from the other party's FAX 1 via the data transmission circuit 11.
A signal is transmitted to the key telephone system control main unit 3.
Then, the centralized control circuit 5 of the key telephone system control main unit 3 enters an automatic transfer sequence.

On the other hand, when the FAX signal detection circuit 10 of the FAX connection adapter 9 does not detect the FAX signal, it is determined that the call is a general call and the first extension telephone 7 is timed out.
Alternatively, the second extension telephone set 8 is put into a call state. When the automatic transfer sequence is entered as described above, the line loop circuit 19 temporarily loops to release the line from the extension telephone 7 (8) that responded and connect it to the FAX connection adapter 9 The extension telephone 7 (8) is instructed to open and the FAX connection adapter 9 is instructed to connect the FAX.

When a FAX connection is instructed, the FA
The sub-control circuit 12 of the X connection adapter 9 switches the switching relay 18 (FIG. 1) to the single FAX 13 side, and requests the line connection. And the line is a standalone FAX13
When the line loop circuit 19 connected to the side is opened, the FAX communication with the standalone FAX 13 and the partner FAX 1 is started. During the line opening operation of the extension telephone 7 (8), the responder is informed of that fact through the display and a completion tone is sent out. When the FAX communication is completed, the line is disconnected, the FAX connection adapter 9 confirms the completion, and the fact is transmitted to the centralized control circuit 5 of the key telephone system control main unit 3 to wait the system again. Put in a state.

FIG. 4 shows a second embodiment, and is a block diagram showing an operation mode based on the configuration of FIG. As shown in FIG. 1, the signal from the FAX network 20 is transmitted to the analog exchange 2 on the receiving side, and the incoming signal is F of the key telephone system control main unit 3.
The data is transmitted to the AX network incoming circuit 21 and further centralized control circuit 5
It is supposed to be transmitted to.

With such a configuration, when a network incoming signal is input from the FAX network 20, it is transmitted to the FAX network incoming circuit 21 of the key telephone system control main unit 3 via the analog exchange 2 and the signal is detected. . In this case,
It goes without saying that unlike the signal from the other party's FAX1, the 16 Hz incoming signal does not come. Then, the centralized control circuit 5 of the key telephone system control main unit 3 judges that it is a signal from the FAX network 20 and does not issue a ringing instruction to the extension telephones 7 and 8 directly, but directly to the FAX connection adapter 9 as a single FAX 13.
Enter the automatic transfer sequence to connect the line to.

In this way, the FAX connection adapter 9 instructed to operate via the data transmission circuit 6 is a single FAX 1
Ring to 3 Then, the standalone FAX 13 responds and connects the line. Then, when the switching relay 18 is switched to the single FAX 13 side and set to the automatic response state, the FAX communication becomes possible. On the other hand, when the FAX communication is completed, the standalone FAX 13 disconnects the line, the FAX connection adapter 9 confirms the completion, and transmits it to the centralized control circuit 5 of the button telephone system control main unit 3,
Put the system in standby again.
