And the message to FAXK will be sent continuously. Therefore, not only the transmission side terminal but also the reception side terminal can transmit a message to a plurality of facsimile terminals by one communication, communication efficiency is greatly improved, communication time is shortened, and communication cost can be reduced. it can.

Next, the operation will be described. 3 to 5 are views for explaining an embodiment according to the invention described in claims 1 and 2. First, the operator of the reception side terminal of the facsimile apparatus can use the ten-key pad or the like of the operation unit 2 shown in FIG. 1 to cover the terminal in advance in the same building or in the same area where the terminal is installed. The telephone number or ID code of another facsimile terminal is input and registered in the memory unit 5.

Next, when performing communication, as shown in the sequence chart of FIG. 5 (a), ringing and a calling tone signal (CNG: Calling tone) are sent from the transmitting side to the facsimile terminal on the receiving side to generate a call. A call is made, and the receiving terminal receives a called terminal identification signal (CED: Called Status).
on Identification) (step 10 in FIG. 3)
0).

Upon reception of the above reception, the receiving terminal receives the SCU.
The memory unit 5 stores the telephone numbers or ID codes of other facsimiles that can be covered by the terminal 1 registered in advance.
Read from the standard function identification signal (NSF: Non-St
andard Facilities) in a predetermined area (Step 1
01), and at the same time, the above-described function of the present invention (this function)
Set the bit in the area that declares the presence or absence of "1".

The SCU 1 then calls the NSF signal and the called terminal identification signal (CSI: Called Subscriber Identifi).
cation) and digital identification signal (DIS: Digital Id
The communication control unit 7 is instructed to send an (entification signal) to the terminal on the sending side, and sent (step 102).
As shown in FIG. 5B, the NSF signal is composed of an area showing the contents of normal NSF, an area showing the presence or absence of this function, and an area storing the telephone number and the like. .

The SCU1 of the sender terminal receives the received NSF
The presence or absence of this function of the receiving side terminal is judged by looking at the signal (step 103), and if there is no this function, it is normally received (step 104). When the function is provided, the telephone number sent to the predetermined area of the memory unit 5 and the data having the function are stored. Then, the SCU1 of the transmitting terminal is
Non-standard function setting signal (NSS: Non-Standard facilitie)
s Set-up) to instruct the communication control unit 7 to send,
The destination of the electronic message stored in the memory unit 5 is searched and it is checked whether or not there is a corresponding destination. If there is a corresponding electronic message, information about the electronic message is stored.

Next, the SCU 1 on the transmitting side instructs the communication control section 7 to send the training signal to the terminal on the receiving side. When the training signal is not accepted (step 105), the receiving side terminal sends a training failure signal (FTT: Failure to Train) (step 106). On the other hand, the receiving side terminal checks the received training signal, and if it is OK, instructs the communication control unit 7 to send out a reception preparation confirmation signal (CFR: Confirmation to Receive), and sends it out ( Step 10
7).

Next, image information (telegram) is transmitted from the transmission side terminal (FAXA) and received by the reception side terminal (FAX1) (step 108). If the message is not completed (Step 1
09), the receiving terminal receives the message confirmation signal (MCF:
Message Confirmation) is transmitted to continue receiving the image information (step 110). When the transmission and reception of the image information is completed, the SCU 1 of the transmission side terminal searches for the destination of the electronic message stored in the memory unit 5 and determines whether or not there is an electronic message addressed to the facsimile terminal covered by the reception side terminal. I will check. As a result of the check, if the electronic message to be transmitted is stored in the memory unit 5, the SCU 1 of the transmission side terminal sends the procedure end signal (EOP: End of Procedures) for this function.
Is set to instruct the communication control unit 7 to send (FIG. 5).
(See (c)).

The SCU1 of the receiving side terminal judges whether or not there is a message addressed to another facsimile terminal which can be covered by the own terminal, depending on whether or not the EOP signal is received (step 11).
1) If there is a message, an MCF signal is sent (step 112). The SCU1 of the transmission side terminal receives this MCF signal and further sends out an NSS signal in which the destination such as the telephone number of the electronic message to be transmitted is stored (FIG. 5).
(See (d)).

The SCU 1 of the receiving side terminal receives the telephone number of this destination and stores it in the memory section 5 (step 11
3) Send out the CFR signal to the terminal on the transmitting side. The SCU 1 of the transmission side terminal transmits the image information, the reception side terminal receives the image information, and stores it in the memory unit 5 (step 115). If the EOP signal is not received (step 116), the receiving side terminal sends the MCF signal (step 117) because the message has not been completed, and returns to step 115.

The SCU 1 of the transmission side terminal receives the MCF signal and repeats the transmission of the image information. When the transmission of the image information is completed, the EOP signal is set and the communication control unit 7 is instructed to transmit the signal. When the receiving side SCU1 receives the EOP signal and ends the electronic message, the process returns to step 111, and if there is no received electronic message addressed to another facsimile terminal, the receiving side SCU1 sends the MCF signal and ends the communication. (Step 118).

As described above, the image information addressed to the facsimile terminals in the same premises or in the same building which the receiving side terminal receives from the transmitting side terminal can be converted into image information for each destination from the receiving side terminal after the communication is completed. It is transmitted by the normal transmission procedure. Therefore, even if a message is sent to a facsimile terminal in the same area or in the same building with a different destination, if it is registered as a facsimile terminal that can be covered by the receiving terminal, the sending terminal Can send electronic messages to a plurality of facsimile terminals with one communication. In this way, by allowing the receiving side terminal to receive the telegram on behalf of the user, the number of times of communication seen from the transmitting side terminal can be reduced, so that the communication efficiency is improved, the communication time is shortened, and the communication cost is reduced. Can be reduced.

Next, FIGS. 6 to 8 are views for explaining one embodiment of the invention according to claims 3 and 4. First, the operator of the transmission side terminal of the facsimile apparatus installs the terminal in advance in the same building or in the same area where the terminal is installed before performing communication using the numeric keypad of the operation unit 2 shown in FIG. However, the telephone number or ID code of another facsimile terminal that can be covered is input and registered in the memory unit 5.

Next, in the case of communication, as shown in the sequence chart of FIG. 8A, the transmitting side makes a call to the receiving side facsimile terminal (step 20 in FIG. 6).
0), calling tone signal (CNG: Calling tone)
Is transmitted (step 201). The reception side terminal sends out a CED signal upon reception of the above, and instructs the communication control unit 7 to send out an NSF signal, a CSI signal and a DIS signal to the transmission side terminal, and the transmission side terminal NS
The F signal, the CSI signal and the DIS signal are received (step 202).

The SCU1 of the transmitting terminal receives the received NSF
The presence or absence of this function of the receiving side terminal is judged by looking at the signal (step 203), and if there is no this function, it is normally transmitted (step 204). If this function is provided, the telephone number of another facsimile terminal covered by the sending terminal is set in the NSS signal, and the communication control unit 7 is instructed to send it (step 205).

The SCU1 of the receiving side terminal checks whether or not the destination information received by the NSS signal is included in the destination information of the electronic message stored in the memory, and if there is, the result is checked by the receiving side terminal. It is stored in a predetermined area of the memory unit 5. Next, the SCU 1 on the transmitting side instructs the communication control unit 7 to send the training signal to the terminal on the receiving side (step 206), and the terminal on the receiving side checks the received training signal, and if it is OK. Send the CFR signal.

If the CFR signal is not received, the SCU 1 of the transmission side terminal repeats the above operation three times (step 208), and if it receives the CFR signal, it sends a message (step 209). The sending side terminal repeatedly sends the message until the sending of the message is completed (step 21).
0, 211). When all the transmission of the electronic message from the transmitting side terminal is completed, the transmitting side terminal sends out an EOP signal (step 212).

After receiving the EOP signal, the SCU1 of the receiving side terminal sets a bit in the MCF signal for transmitting a message to the destination of another facsimile terminal covered by the transmitting side terminal (FIG. 8 (b)). (See), the communication control unit 7 is instructed to transmit, and the transmission side terminal receives the MCF signal (step 213). Next, at step 214, it is judged whether or not there is a telegram addressed to the other facsimile terminal that can be covered by the sending side terminal from the receiving side terminal, and if not, a disconnection command signal (DCN: Disconnect) is issued and communication is performed. finish.

If there is a message, SCU1 of the receiving terminal
Sets an NSS signal, instructs the communication control unit 7 to send the signal, and sends it to the terminal on the transmitting side. The SCU1 of the sending terminal is
The MCF signal and the NSS signal are received (step 216), the mode is changed to the reception mode, and the reception mode is instructed to each unit. Next, the sending terminal receives the message sent from the receiving terminal to the sending terminal and sends it to the memory NS.
The data is stored in a predetermined memory area in association with the telephone number or the like stored in the S signal (step 217).

Then, the transmitting side terminal receives the electronic message from the receiving side terminal (step 218) and repeats until the electronic message reception is completed (step 219). Next, the sending side terminal reads out the destination of the message sent from the receiving side terminal from the memory unit 5 and calls another facsimile terminal covered by the sending side terminal (step 220) to perform normal protocol exchange. Is performed (step 221), and the transmission process is performed until the transmission of the electronic message is completed (steps 222 and 22).
3), the communication ends when the message transmission ends.

As a result, the facsimile apparatus of the above embodiment happens to be in the memory of the receiving side terminal in the memory of the receiving side terminal when the transmitting side terminal sends the electronic statement or in the same area as the transmitting side terminal. If there is a telegram addressed to a facsimile terminal that can be covered by the sender terminal, such as in the same building, multiple telegrams are sent and received between mutual facsimile terminals in one communication without disconnecting the line. . In other words, the line used to send a message from the sending terminal to the receiving terminal was used to send the message to the sending terminal from the receiving terminal, so the number of communications seen from both the receiving and sending sides Can be reduced. Particularly in the case of the G3 facsimile apparatus, since the protocol requires a long time, the communication efficiency improves as the number of times of communication decreases, so that the communication time can be shortened and the communication cost can be reduced.
