is an auto-dial device that automatically dials the destination.

The communication control device 14 creates information for transmission control, converts it from parallel to serial, and then outputs it to the modem 13 .

FIGS. 3(a) and 3(b) respectively show G2. 3 is a sequence chart showing each transmission procedure of G3.

In FIG. 3(a)L, first, the relay side 17 makes a call and seizes the line to the other party 18, and then the other party 18 sends a CHD' (identification signal 21 indicating that it is a machine).
00Hz) for 3 seconds, then exit Gj (identification signal 1850Hz indicating that it is a 02 aircraft) for 1.5 seconds (3
second pause). Therefore, the broadcaster temporarily disconnects (19)
, Then, after the sensitization end point 20 of the 02 image signal, the call is made again and the other party sends back cap and at, and the GC (acceptance signal 2100Hz) is sent for 1.5 seconds and the phase signal (2,100Hz ) for 6 seconds each to synchronize
CFR (ready signal 1650Hz) from the other party.
) is returned for 3 seconds, PiX (image signal 21
00H2) and have the other party print it. After this, control signals are exchanged as before.

Next, in FIG. 3(b), first, by making a call from the broadcasting side 17, the other side 18 sends CED and DiS (
Since the digital identification signal (device 03) is returned, the broadcasting side temporarily disconnects at this point (19). The broadcast side makes a call again when the G3 image signal has been created (21). When CED and DiS are returned from the other party 18, the broadcasting side sends DC8 (mode setting command) and TCF (training check signal). When the other party returns CFR (ready), the broadcasting side sends out PiX (picture signal).

FIG. 4 is an operation flowchart of the main CPtJ shown in FIG.

The main CPU first determines whether or not facsimile communication has started (202), and if it has started, determines whether there is information about the other party in the memory 2 (20).
3) If not, receive and receive partner information from FCU6 (20
4) It is determined whether the other party is 62 or G3 (205).

After creating G2 data or G3 data thereby (
206, 207), and transfers the data to the local memory 10 of the FCU 6 (208). The FCU 6 takes in this data and starts communication (209).

FIG. 5 is an operation flowchart of the FCU CPU shown in FIG.

First, if communication has not been started (302).

If the other party information has not been determined (315), it is determined that if the calling signal Gi is G2 information, and if it is DiS, it is G3 information (317-320), Di.

The line is temporarily disconnected (321, 322), including in cases where there is a signal other than DiS or no return. Then, these discrimination information (G2 and G3 information) are transferred to the main CPU (323).

Then, return to the start, start 1 communication, and call the other party by dialing (301°302.3
03). G2 or G3 sends and receives control signals for the G2 procedure or G3 procedure (304 to 30g), sends the image signal, and if it ends normally, disconnects the line and completes the communication (309 to 311). . If the process does not end normally, the line is temporarily disconnected and information to that effect is transferred to the main CPU (309, 312, 313). Then, start over again from the start (314).

The above operations enable the broadcasting device to effectively utilize the connected lines.

In conventional sequential broadcast communication, for example, after one G2 communication,
After 3 minutes, move on to the next G3 communication (9600bps),
After 20 seconds, move on to the next communication.

However, in the present invention, by providing the data processor 3, the scanned monochrome signal is transferred to each local memory 10 of each FCU 6 within 2 seconds at a time in accordance with each mode. Therefore, data transfer for 10 lines is completed in 20 seconds, and each fax machine of different models (2, G3, etc.)
In the case of simultaneous broadcast communication to IO units, the process that previously took 10 communication times can be completed in 20 seconds + 1 communication time. Furthermore, if the function of the other party is unknown, only the dialer time and the time for sending Gi and DiS signals once are added.

Effects As explained above, according to the present invention, in facsimile circular communication, recipient information is automatically taken in without the user's intervention, and at the same time, data is transmitted in accordance with the recipient information. Because it can be created and sent to two different devices at once, data sending time can be shortened.
