Conventional fax function units (fax transmission means) 5 and 6 of each fax machine 1 and 2 are parts that perform the function of a conventional fax machine, and receive a transmission start signal from a called number verification common control unit 11 and 12, which will be described later. When this is entered, the user is ready to send a fax.

The telephone number setting unit (information holding means) 9.10 is constituted by a semi-fixed switch, and the telephone number information of each telephone 3.4, for example r 765-4321, is set by the switch.
J and r 567-1234 J are each retained.

The confirmation numeric information transmitting/receiving units 7 and 8 are parts for transmitting and receiving information with the connected fax machine. In particular, when operating as a receiving party, they function as information transmitting means, and send telephone calls to the originating fax machine. While transmitting the telephone number information held by the number setting units 9 and 10, when operating as a calling party, it functions as an information receiving means and receives telephone number information sent from a receiving party's facsimile machine.

Dial code recording unit (information recording means) 15.16 is
When a telephone number is dialed on a telephone set 3.4 connected to the device, the receiver picks up the signal and records the dial code.

The called number verification section (information verification means) 13.14 verifies the telephone number information received by the transmitting/receiving sections 7 and 8 with the telephone number information recorded in the dial code recording section 15.16, and outputs the result. It is given to the called number verification common control units 11 and 12.

The incoming number verification common control unit (control means) 11.12 sends a communication start signal to the conventional fax function unit 5.6 when the two telephone number information match in the number verification unit 13.14. Output.

In addition, the control unit 11.12 includes transmitting/receiving units 7 and 8, a number matching unit 13.14, and a recording unit dial code recording unit 15.
, 16, and instructs the start of operations.

Next, the operation will be described using as an example the case where the fax machine 1 is the sending side and the fax machine 2 is the receiving side.

When the user picks up the handset of the telephone 3 to send a fax, the control section 11 receives the signal and instructs the dial code recording section 15 to prepare for reception.

Next, when the user dials the telephone number r567-1234J of the destination fax machine 2, that is, the telephone 4, the dial code recording section 15 receives the signal and records the dial code.

In parallel with this, by operating the dial above, the conventional F.7
A general connection is made through the communication channel 17,
It is connected to the facsimile machine 2 via an exchange 19 and a communication path 18 . As a result, the fax machine 2
The control section 12 is activated via the conventional fax function section 6, and the conventional fax function section 6 instructs the information transmitting/receiving section 8 to input the telephone number information r567 held by the telephone number setting section 10.
-1234 J is sent to fax machine 1.

In the facsimile machine 1, the transmitting/receiving section 7 receives the telephone number information from the facsimile machine 2, and notifies the control section 11 of this fact. When the control unit 1■ receives this notification,
The number verification section 13 is instructed to perform verification of telephone numbers. Here, the number verification section 13 verifies the telephone number information received by the transmitting/receiving section 7 from the fax machine 2 and the telephone number information recorded by the dial code recording section 15, and notifies the control section 11 of the result. do.

The control section 11 outputs a communication start signal to the conventional facsimile function section 5 to enable facsimile transmission only when the two telephone numbers match as a result of the comparison in the number matching section 13. The control unit 11 also transmits this communication start signal to the facsimile machine 2 through the transmitting/receiving unit 7.

In the facsimile machine 2, when the transmitter/receiver section 8 receives the communication start signal, it sends it to the control section 12, and the control section 12 thereby controls the conventional facsimile function section 6 to enable facsimile reception.

On the other hand, if the two telephone numbers do not match as a result of the verification in the number verification section 13, the control section 11
causes the fax machine 1 to perform a recovery operation, and also sends a predetermined signal to the fax machine 2 to cause it to perform a similar recovery operation.

In this way, the fax machine of the present invention performs fax transmission only when the telephone number of the dialed destination matches the telephone number of the fax machine terminal of the destination actually connected through the exchange. This prevents faxes from being sent to the wrong recipient due to incorrect connection.

In this example, in order to further increase the reliability of preventing erroneous transmissions, the conventional fax function section 5 not only controls the transmission capability of the conventional fax function section 5 based on the telephone number verification result in the number verification section 13, but also controls the conventional fax function of the fax machine 2. The configuration is such that it also controls whether or not the unit 6 can receive data. However, it is not necessarily necessary for the facsimile machine 2 to also control whether reception is possible, and the object of the present invention can be achieved by simply controlling whether transmission is possible on the sending side.
