Abstract

PURPOSE:To attain a simultaneous multi-address communication and individual communication even through a radio channel for which press transmission is necessary while using a G3 general facsimile by controlling a signal from a radio equipment and a signal from a facsimile so as not to be overlapped. CONSTITUTION:Adaptors 11 and 21 of a transmission station 1 and a reception station 2 are equipped with an incoming control function which controls an incoming call from the radio channels, press control function, and signal delay function. In the transmission station 1, a signal from a facsimile 10 is detected by the adaptor 11, and a press signal is transmitted from the adaptor 11. In the reception station 2, a channel response signal is returned from the adaptor 21 in response signal is returned request from a radio equipment 20, an activation signal is transmitted to a facsimile 22, and a signal from the facsimile 22 is transmitted to the transmission station 1 in a timing in which the signal is not overlapped with the signal outputted from the radio equipment 20. In the transmission station 1, the signal from the reception station 2 is confirmed, the start button of the facsimile 10 is pressed, and a transmitting state is obtained.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile communication system using a wireless line.

[0002]

2. Description of the Related Art FIG. 4 is a block diagram showing an outline of a system configuration for explaining a conventional facsimile communication system using a wireless line. In the figure, 1 is a transmitting station, for example, a G3 facsimile 15, It is composed of an exchange 16 and a radio 17. Reference numeral 2 denotes a receiving station, which, like the transmitting station 1, includes a wireless device 23, an exchange 24, and a G3 facsimile 25.

In the conventional facsimile communication method using a wireless line, when it is desired to use a general G3 general-purpose facsimile, the G3 facsimile has a 2W specification and does not have a press control signal. Need to use. FIG. 5 is a diagram showing a transmission procedure of a facsimile communication system using such a multiplex wireless line.

[0004]

As described above, in the conventional facsimile communication method using a wireless line, when it is desired to use a G3 general-purpose facsimile, the use is limited to only multiple wireless lines, and thus lacks versatility. There is a problem of being limited. In particular, even for requests such as easy simultaneous broadcast using the disaster prevention administrative wireless line,
In the case of the G3 facsimile, there is a problem that it has to use multiple wireless lines.

The present invention has been made to solve the above problems, and provides a facsimile communication system capable of performing simultaneous broadcast communication and individual communication even on a wireless line requiring press transmission while using a G3 general purpose facsimile. It is intended to be provided.

[0006]

A facsimile communication system according to the present invention comprises an incoming call control means for controlling an incoming call from a wireless line, a press control means and a signal delay means for each terminal station. The control is performed so that the signal and the signal from the facsimile do not overlap with each other, and the control is performed so that the response signal from the facsimile is not transmitted if necessary.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an outline of a system configuration for explaining a facsimile communication system of the present invention. In the figure, 1 is a transmitting station, for example, a G3 facsimile 10,
It is composed of an adapter 11, a wireless device 12, a simultaneous command device 13, and a wireless device 14. Reference numeral 2 denotes a receiving station, which, like the transmitting station 1, is composed of a wireless device 20, an adapter 21, and a G3 facsimile 22. The adapter of each station has an incoming call control function for controlling an incoming call from a wireless line and a press. It has a control function and a signal delay function.

FIG. 2 is a diagram for explaining the transmission procedure (individual communication) when the number of receiving stations is one in the facsimile communication system of the present invention. As shown in FIG.
Then, when the adapter 11 detects a signal from the facsimile 10, the adapter 11 sends a press signal. Further, when connecting from the transmitting station 1 to the receiving station 2 via a relay station (not shown), it is necessary to send a signal for identifying the radio device such as an ID number before and after the text transmission.
In this case, the press signal and the image signal must be delayed with respect to this specific signal, and the adapter 11 performs this delay.

In the receiving station 2, in response to the line connection request from the wireless device 20, the adapter 21 sends back a line response signal, and then sends a start signal to the facsimile 22, and signals (CED, DIS) from the facsimile 22. Is transmitted to the transmitting station 1 with timing so that it does not overlap with the signal output from the wireless device 20. The operator of the transmitting station 1 confirms the signal from the receiving station 2 and presses the start button of the facsimile 10 to put it in the transmitting state. After that, the transmitter / receiver facsimiles 10 and 22 and the adapter 1
1 and 21, communication is started according to the G3 FAX procedure, communication between the facsimiles 10 and 22 is ended after the transmission of the document is completed, and the state returns to the standby state.

FIG. 3 is a diagram for explaining a transmission procedure (simultaneous broadcast communication) in the case where the same document is simultaneously transmitted from one transmitting station 1 to a large number of receiving stations such as a disaster prevention administrative wireless line. In the case of the simultaneous broadcast communication in which a plurality of stations are connected in parallel to the same channel, the communication between the transmitting station 1 and the receiving station 2 is difficult to perform with only the G3 facsimile, so the receiving G3 facsimile 22 It is necessary to absorb the response signal from the facsimile 22 by the adapter 21 in front of.

That is, as shown in FIG. 3, a plurality of receiving stations 2 (see FIG.
Then, only one station is shown), and then a facsimile image signal is transmitted in the broadcast format.
The adapter 21 of the receiving station 2 monitors whether or not the facsimile signals of the transmitting station and the receiving station are normal until the end of communication. Then, if necessary after the end of communication, a confirmation signal is returned. Further, the broadcast command device 13 of the transmitting station 1 displays the result of the FAX broadcast and the like according to the content of the confirmation response signal from each receiving station 2, and the broadcast command device 13 receives the confirmation response signals from all the receiving stations. In this case, or after the lapse of a specified time, a broadcast end signal is sent to end the FAX broadcast communication.

Incidentally, in FIG. 2, FIG. 3 and FIG.
Is called station identification, DIS is digital
The identification signal is the DCS digital command
signal, TCF for training check, CFR for confi
rmation to receive, MPS multi-page signal
, MCF gives the massage confirmation, EOP the end
of procedure, DCN indicates disconnect.

[0013]

As described above, in the facsimile communication system of the present invention, each terminal station is provided with an incoming call control means, a press control means and a signal delay means for controlling an incoming call from a wireless line. By controlling so that the signal and the signal from the facsimile do not overlap, and controlling not to send the response signal from the facsimile if necessary, it is possible to use the G3 general-purpose facsimile to broadcast all over the wireless line that requires press transmission. Broadcast communication and individual communication are enabled, and there is an effect that the range of use of facsimile wireless communication using a general-purpose facsimile can be expanded.
