In response to the NSF%C3I, Dis from FAX-A, FAX-B sends a non-standard function command signal N5C1 in response to the NSF signal, indicating an ID such as the telephone number of the calling terminal FAX-B. In response to the terminal identification signal CIG and the Dis signal, it sends out a digital transmission command signal DTC indicating that it has a standard function.

As shown in FIG. 4(B), the non-standard function command signal NSC includes a non-standard model identification item, a relay function presence/absence item, a polling reception presence/absence item indicating presence/absence of polling reception, and a polling ID presence/absence item. , a terminal ID presence/absence field, and a polling ID field in which the respective identification numbers are entered if a polling identification number is present or if an individual identification number of the terminal device is present;
It has 10 terminal items, etc.

In response to the NSC, CIG, and DO3 from FAX-B, FAX-A sends a sending terminal identification signal TSI indicating the sending side FAX-A and a non-standard function setting signal NSS as a response signal to the non-standard function command signal NSC. Send out.

By the way, in the present invention, this non-standard function setting signal NSS includes, in addition to the model identification term, as shown in FIG. 4(C).
From FAX-A to FAX-B, a relay broadcast request manuscript field that indicates whether there is a relay broadcast request manuscript to another facsimile machine, and a broadcast number that indicates the number of relay broadcast destinations when it is a relay broadcast request destination. field, and the multicast destination data I, such as the telephone number or identification number of the multicast facsimile, for the number of multicasts. Note that the example in FIG. 4(C) shows a case where the number of broadcasts is three.

Note that FAX-A outputs a modem training check signal TCP following the TSL and NSS, and FAX-B
In response to this, sends a reception preparation confirmation signal CFR indicating that message sending may be started.

After seeing this CFR, FAX-A sends image data PIX, and when this is finished, sends out a procedure end signal EOP. FAX
-B thereby sends a message confirmation signal MCF as an acknowledgment of the EOP, indicating that the message has been completely received. FAX-A sees this and sends a disconnect command signal D.
CN is transmitted, and the relay request based on polling is terminated. If the image data consists of multiple pages and there is still image data to be sent, a multi-page signal M is sent instead of EOPO.
After sending PS and receiving MCF, image data PIX (R
TC) will be transmitted.

For FAX-B, facsimile FAX-C and D are designated as broadcast destination data 1.2.3 of the non-standard function setting signal NSS shown in FIG. 4(C).

A process is performed to output the image data requested by FAX-A to FAX-A.

For this reason, as shown in Figure 3, FAX-B is first
-Sends 1611z ringtone to FAX-C
The called terminal identification signal CED is received from the terminal, and then NSF, C3I, and DIs are received in the same manner as above. In response, FAX-B sends TSI and NSS, sends TCP, performs a modem training check, receives CFR, and then first receives the image data P from FAX-A.
Send IX and send EOP. And MO for this
When receiving F, it sends DCN and ends relay broadcast transmission of one page to FAX-C. If the image data consists of multiple pages and there is still image data to be sent,
Sends MPS instead of OP, and sends PIX after receiving MCF.

FAX-D, E, which is the recipient of the relay broadcast request,
sequentially.

Next, regarding the operation of the facsimile apparatus of the present invention shown in FIG. 2, the operations as a relay broadcast requesting side and a relay broadcast side will be explained based on FIGS. 5 to 7.

(A) Regarding the operation of the facsimile FAX-A side (1) Setting the relay broadcast destination on the FAX-A When there is data to be requested for broadcast at the time of polling, the operator on the FAX-A side sets the original to be transmitted, and selects the polling setting menu from the initial screen on the display unit 1, as shown in FIG. From this screen, select "Send" and then select "Broadcast". Then, after inputting the first telephone number rQ 4'l 3-xx-xxxxJ from the key input section 2, the user presses the cent key. As a result, the processor 15 sets the number of relay broadcasts to 1, and converts this input telephone number into a binary code I
It is converted into O-adic code BCD, AHrlolobJ is added afterwards, and it is sent to the backup RAM 9. When the broadcast destination telephone number is input in this way and the set key is input, the processor 15 increments the number of relay broadcasts by +1, converts the telephone number to BCD, adds AH to the end, and stores it in RAM 9 for back amplifier. are set sequentially. After inputting all the necessary broadcast destinations in this way, pressing the stop key on the keypad unit 2 completes the registration, and the processor 15 creates the NSS as shown in FIG. 4(C). .

(2) Operation of FAX-A in response to polling from FAX-B■ FAX-A outputs CED as described above in response to the 16Hz call signal from FAX-B, and then outputs NSF
, C3I, and DIS are sent.

Then, a response to this from FAX-B is received.

(2) If the NSC does not exist in the response reception signal from FAX-B, the processor 15 performs the corresponding reception procedure.

■ If NSC exists in the response signal from FAX-B,
The processor 15 decodes this and checks the polling ID term, and the polling ID is FAX-A.
A comparison is made to see if it matches D. If they do not match, the communication termination procedure is performed.

■ If the polling ID in the NSC and the polling ID of the FAX-A match, the processor 15 checks whether or not there is a relay broadcast request setting for the own machine as in (11) above.As a result of this check, If there is a relay broadcast request setting, the processor 15 checks whether there is a relay function in the NSC, and when the other party's FAX-B recognizes that there is a relay broadcast request, it sends the TSI and NSS to the FAX-B. do.

In this way, the broadcast destination data set in the bank-up RAM 9 is sent to the FAX-B.

(2) After transmitting TSiNSS in this manner, FAX-A transmits TCF to FAX-B to train the other party's modem. As a result, when receiving the CFR sent from FAX-B, the processor 15 recognizes that the message sending has started, reads the document set in FAX-A with the reading unit 13, and temporarily sends it to the line. After being stored in the memory 12, compressed data is created in the compression/decompression unit 11, and this compressed data is stored in the compressed data save memory 10, and then sent by FAX via the modem 3.
- Send to B. After the image data is transmitted in this manner, a communication termination procedure from FAX-A to FAX-B is performed.

(3) Operation of FAX-B in response to relay broadcast request from FAX-A■ FAX-B is NSF%C8I, DN from FAX-A
When S is received, N5CSCIGSD is sent to FAX-A.
Send TC.

(2) On the other hand, when the processor 15 receives response signals TSI and NSS from FAX-A, it checks the relay broadcast request setting item in the NSS. As a result, if there is a number of relay broadcasts, the pro sensor 15
S saves the broadcast destination data, that is, the number of broadcasts and the broadcast destination data 1.2.- in the backup RAM 9.

At this time, first write the number of broadcasts in the OFF section, then write the telephone number, and write the one-case completion flag A as a separator. Then FA
X-B is FAX- when training is OK in response to training check signal TCP sent from FAX-A.
The CFR is sent to FAX-A, and the image data sent from FAX-A is received. This image data is held as compressed data in the compressed data save memory 10.

Then, the above-described termination procedure with FAX-A, which is the polling destination, is performed.

■ Then, on FAX-B, the backup R
The number of broadcasts saved in AM9 is saved in a counter (not shown). Of course, instead of setting it in the counter, the number of broadcast destinations may be saved in a register (not shown).

■ Next, the processor 15 reads the broadcast destination data 1 which is the telephone number of the first broadcast destination (for example, FAX-C) saved in the backup RAM 9, and sends it to the NCU 4. performs the calling operation.

(2) As a result, the communication control as explained with reference to FIG. 3 is performed between FAX-B and C, and the image data PIX that was requested to be relayed by FAX-A is sent out. After the termination procedure is executed, the processor 15 calculates the number of broadcast destinations set in the counter (or register) by -
Do 1. Such processing is sequentially performed for all request destinations, and when the number of multicast destinations set in the counter (or register) reaches zero, the multicast ends.

〔Effect of the invention〕

According to the present invention, since the requested station makes a polling call, communication is not impossible because the requested station is in use when the requesting station requests relay broadcasting, and smooth relay broadcasting is possible. Can communicate. Furthermore, since the calling party pays for polling, the requesting station, which is a polling transmitting station, can request relay broadcasting without having to pay any fees.
