2. Description of the Related Art When transmitting a facsimile document with the same content from one facsimile machine to a plurality of facsimile machines, broadcast transmission has been used to reduce communication costs and distribute communication traffic.

In normal relay broadcast transmission, when a relay broadcast requesting station sends a facsimile document and the subscriber numbers of multiple transfer stations to the relay station, the relay station transmits the facsimile document to the specified multiple transfer stations. Forward.

Furthermore, in so-called multiple relay broadcasting, when a requesting station transmits a facsimile document and the subscriber numbers of multiple transfer stations to a first relay station, some of the transfer stations function as second relay stations, and Forward the facsimile document to a registered retransfer station.

By the way, in the above-mentioned relay broadcast transmission, when the requesting station instructs the relay station to broadcast broadcast transmission, all the subscriber numbers of each transfer station must be input, so the operation is complicated. There was a problem.

[0006] For example, Japanese Patent Laid-Open No. 155669/1983
In the publication, multiple broadcast lists that can be selected by ID number are registered in advance in the relay station, and when the requesting station sends the ID number and image information to the relay station at the time of broadcast transmission, the relay station A technique has been proposed for transmitting image information to transfer stations registered in a broadcast list selected by ID number.

[0007] Furthermore, for example, Japanese Patent Laid-Open No. 194544/1999 proposes a technique for making the above-mentioned transmission method using a broadcast list applicable to multiplex relay broadcast transmission. .

On the other hand, in the relay broadcasting and multiple relay broadcasting described above, in order to enable the requesting station to confirm the completion of transmission,
The subscriber number of the requesting station is registered in advance in the terminal station, and when the terminal station receives image information, the received image information is sent back to the requesting station.

However, in such a configuration, if a communication problem occurs between the relay station and the terminal station, the image information is not returned to the requesting station, so although it is possible to recognize the occurrence of the problem, it is difficult to know how far the transmission will go. There was a problem in that it was not possible to determine whether the

[0010] Therefore, for example, Japanese Patent Laid-Open No. 189864/1986
In order to solve such problems, the following transmission method is proposed in the publication.

[0011] That is, the requesting station transfers its own subscriber number and the number of transfer destinations together with image information to the transfer station, and the transfer station transfers the subscriber number of the requesting station as is, and the number of transfer destinations is one. It is incremented or decremented and transferred to the next transfer station along with the image information. In other words, each transfer station is
Each time a transfer is made, the number of transfer destinations is incremented or decremented by one.

[0012] If the transfer to the next transfer station cannot be performed correctly at the transfer station on the way, dial the subscriber number sent from the requesting station and confirm the transfer with your own subscriber number. Reply with the number of recipients.

According to such a configuration, the requesting station can accurately recognize the station number of the final transfer station and the number of transfer destinations.

[0014]

[Problems to be Solved by the Invention] In the above-mentioned conventional technology, in a broadcast transmission method that uses a broadcast list to simplify operations, when a communication problem occurs between a relay station and a terminal station, it is difficult to transmit No method has been proposed to determine how far the process has been executed.

[0015] An object of the present invention is to solve the above-mentioned problems and to provide a multicast transmission system using a broadcast list, so that it is possible to easily determine how far the transmission has been carried out when a communication trouble occurs. The purpose of the present invention is to provide a relay broadcast transmission system with a high level of accuracy.

[0016]

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention provides a facsimile communication system including a facsimile device having a function of storing image information. The system is characterized in that a reply destination to which the broadcast results are returned to each destination is registered along with the broadcast list code and the broadcast list code.

[0017]

[Operation] According to such a configuration, a facsimile machine functioning as a relay station can know the destination for sending broadcast results by referring to the broadcast list, so it can easily send back broadcast results. This makes it easier to manage and understand communication networks.
