Sends GI signal. The facsimile transmitter T receives and detects this GI signal, and if it is a facsimile receiver that can receive the transmitted signal, it will receive the signal within a certain period of time.
Sends GC signal and then sends PHS signal.
The facsimile receiver R receives the GC signal, sets the reception mode to the transmission mode, receives the PHS signal, and performs phase matching. When the phase alignment is completed and preparations for receiving the image signal are completed, the CFR signal is transmitted. When the facsimile transmitter receives the CFR, it sends out an image signal, and when it has finished sending out the image signals for one page of the transmitted original, it sends out the EOM signal following the image signals. The facsimile receiver R receives the image signal,
When it receives an EOM signal, it sends out an MCF signal, and after a certain timing, it sends out a GI signal in preparation for the next reception. The facsimile transmitter T receives the MCF signal and recognizes that the image signal for one page has been correctly received. It continues to receive the GI signal, and if there is a second page of the original to be transmitted, it sends out the GC signal and repeats the above operation. When a facsimile receiver cannot receive a GC signal within a certain period of time, it abandons reception and returns to its initial state.

にしたものである。 Next, the operation will be explained using FIGS. 2 and 3. Set the reception destination for each line on the operation panel JKL and start it up. The control circuit CONT is an auto dial circuit from each network control circuit based on the information on the operation panel JKL.
Send dial pulse via AD. When the communication line network NW receives the dial pulse, it calls the receiver R using a known procedure, and when the receiver responds, it sends back a polarity inversion signal (hereinafter referred to as reverse signal) to the transmitter T indicating completion of the line setting. network control circuit
When the NCU receives the lever signal, the control circuit
Contact c of the line that received the reverse signal is closed via CONT, a hold signal is sent from the hold signal source S1, and the responding receiver is temporarily put on hold. After completion of sending dial pulses to multiple lines, relays C1 to CN (not shown) are restored all at once after a certain timing to stop sending out hold signals, and a plurality of receivers are started from the same state all at once. Here, the explanation will be continued using an example in which the sequence starts from the GI signal transmission state of the sequence described above. control circuit
In preparation for receiving the GI signal from the receiver, CONT operates relays D1 to DN (not shown) to switch their contacts d1 to dn to the detection circuits DET1 to DETn. When one or more of the detection circuits DET1 to DETn detects a GI signal within a predetermined timing, the control circuit CONT operates relay B (not shown) and connects its contact b to the control signal source S.
Switch to side 3 and send a GI signal to transmitter T for a predetermined period of time to restore relay B (not shown). When the transmitter T receives the GI signal, it transmits the GI signal as described above.
Sends GC signal and PHS signal. Broadcast device DT
AMP amplifies the GC signal and PHS signal from the transmitter
After sending signals to multiple signal lines simultaneously through AMPn, operate relays D1 to DN (not shown) and switch their contacts d1 to dn to the detection circuit side.
Detects the control signal (CFR signal) from receiver R. The detection circuit DET1 within a predetermined timing
~ When a CFR signal is received at DETn, it operates relay A (not shown) in the same way as the GI signal, switches its contact a to the control signal source S2, and transmits the CFR signal to transmitter T for a predetermined period of time. It is sent to restore relay A (not shown). The MCF signal is also sent to the transmitter T in a similar manner. As described above, in this embodiment, if even one receiver among the plurality of receivers returns a predetermined signal within a predetermined timing, the transmitter is configured to transmit the signal from the broadcasting device. This is what I did.

である。 Note that in this embodiment, the detection circuits DET1 to DETn
is the total signal sent out from the receiver, i.e. GI,
The explanation was given using an example in which all CFR and MCF signals can be detected, but the circuit is designed to be able to detect only particularly important signals such as CFR signals (receivers that do not transmit CFR cannot receive images), and other signals are broadcast. A method of forcibly sending out the information from the device at a predetermined timing is also possible.

て済む等の利点並びに効果がある。 As is clear from the above-mentioned embodiments, according to the present invention, if at least one of the plurality of receivers is operating in the normal procedure, image transmission is possible. Increased completion rate,
In addition, since the control signal from the receiver can be detected in correspondence with the communication line, it is possible to restore the line when the control signal from the receiver cannot be detected within a predetermined timing, eliminating the need to hold the line invalid. Economical. Furthermore, since the system does not require one-to-one communication between the transmitter and the receiver, both the transmitter and the receiver can be standard facsimile machines, and there are advantages and effects such as less hardware required.
