Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an improvement in a facsimile circular communication system using a dedicated line.

[Technical background of the invention and its problems]

Conventionally, as one of the broadcast communication methods, a plurality of child facsimile machines are connected to a broadcast machine connected to a parent facsimile machine via a dedicated line, and a parent facsimile machine is connected to a parent facsimile machine. I
There is a device that broadcasts the transmission information from the J device to each child facsimile device using a relay device.

By the way, there is a demand for collecting messages in such a broadcast communication system. Collection is generally a method in which Kaneko facsimile machines are sequentially called and sent when there is information to be collected.
- Performed by ring method.

However, it has been difficult to achieve both circular reporting and collection because it takes time to collect using the polling method.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a facsimile broadcast communication system that is capable of not only broadcasting but also collecting messages.

[Summary of the invention]

In order to achieve the above object, the present invention provides means for making a call to each child facsimile device, and also provides a means for detecting and displaying the occurrence of the above call to the broadcast device,
In this system, a child facsimile IJ device issues a call and stands by, and each of the devices receiving the call is selectively connected to the parent facsimile device to collect messages.

Next, the relay communication system of this embodiment will be explained based on the above configuration. First, when the master facsimile device 1 issues a command to send a return message, the control circuit 24 of the return device 2 detects the command and activates the transmission switch 12 of the corresponding line circuit 21°2, . . . 12.・・・

Now, child fax machine fff, 4.4. When transmission information is generated from the parent 7 aximmi IJ device 1, that is, when a transmission document is set, the child facsimile devices 4, 4, . . . . sends a calling signal to the broadcast device 2. After sending out this calling signal, the device enters a calling standby state.

On the other hand, in the broadcast device 2, the child facsimile device @ 4

By the way, when a call occurs from a plurality of child facsimile devices 4, 4..., all the child facsimile devices 4, 4. . . . may need to be sent before completing the collection. In such a case, the broadcasting device 2 stops the concentrating operation and each of the corresponding child facsimile devices 4, 4. . . . and then transmits a broadcast signal. On the other hand, child facsimile devices 4, 4. ... receives a signal indicating that the above notification will be made in the transmission standby state.'
Then, the standby state is canceled and the reception standby state is entered, and the notification signal sent from the notification device 2 thereafter is received. In other words, it does not affect the broadcast transmission operation in any way.

Note that when the reception of the above-mentioned broadcast signal is completed, the child facsimile devices 4, 4. . . . will send out the ejection signal again if the original to be sent is 7 bits at that time, and will be in a standby state thereafter. On the other hand, when the broadcasting device 2 finishes the transmission of the broadcast, the child facsimile device flf that has detected the call again, 4.4. ...
Start collecting messages.

In this way, in the repeat communication method of this embodiment, the child facsimile devices 4, 4. . . . issues a paging signal and thereafter maintains a call standby state, detects and displays the paging signal on the broadcasting device 2, and according to the detection result, the child facsimile IJ device 4 * 4 + ・ receives the paging signal. . . . can also be selectively collected from the parent file, thereby further enhancing the functionality of the circulation system. Further, the child facsimile devices 4, 4. In this case, once the calling signal is sent out, the device remains in a standby state, so that the operator only needs to perform an operation to send out the calling signal, and the handling is extremely simple.

Note that the present invention is not limited to the above embodiments.

For example, the collection control operation in the broadcasting device may be such that the operator visually checks the display state of run f18 and manually connects the child factor t IJ device that performs the collection to perform the collection. Further, as an applied example of the present invention, the call once detected may be stored in the broadcast device 2, and after the broadcast transmission is completed, the collection may be restarted according to the stored call information. In addition, the configurations of the communication device and the slave facsimile device can be modified in various ways without departing from the spirit of the present invention.

〔Effect of the invention〕

As described in detail above, the present invention provides a means for calling each child facsimile device, and also provides a means for detecting and displaying the occurrence of the above-mentioned call in the relay device, so that the child facsimile device issues a call and waits. , the communication device that receives the above call is selectively connected to the parent facsimile device to collect the messages.

Therefore, according to the present invention, it is possible to perform not only broadcasting but also collection, and it is possible to provide a highly functional facsimile/return communication system.
