[Industrial applications]

The present invention relates to an improvement of a polling message broadcasting method having a reverse communication function of receiving a broadcast message to a specific facsimile system and automatically returning a polling transmission message.

[Conventional technology]

Conventionally, with the spread of facsimile, a broadcast communication system has been frequently used. Broadcasting when sending one manuscript to many destinations, for example, issuing a command from the head office to each branch, and further to the terminal office, or conversely, when downloading materials from the terminal office to the head office, etc. The system is being used effectively.

One example of a conventional broadcast transmission system is to read a document to be transmitted, convert it into image data, store the image data in a memory, and sequentially connect the contents of the memory to a plurality of destinations to control transmission. The provided facsimile is used.

FIG. 6A shows an application example of a conventional broadcast communication system.
In the figure, for example, a broadcast message A is sent from a head office 1 to a branch office.
2 _1, 2 ₂ ...... or the like to feed, each sales office 3 ₁ further from each Branch 2 ₁ or the like,
It is distributed to 3 ₂ ….

As shown in FIG. 3B, when the terminal office 3 returns the request message a prepared in advance in response to the broadcast message A, the return message a is compiled at the branch 2 through the reverse route. Or to the head office each time. These communication units are transmitted from stations 1, 2 and 3 and each broadcast message or one request message is returned. One communication is required for each communication, so the charge is increased and the broadcast and return are separated. However, there is a problem that the communication may be interrupted "busy" and the yield takes a long time.

On the other hand, a reverse function (this is called a turnaround polling method) according to the polling broadcast message shown in FIG. 3C is proposed. For example, the station 2 transmits the transmission message A, and the station 3 receives the message A. , The transmission message a prepared in advance is immediately returned. For example, since A + a is performed in one communication as in a normal conversation, there is no room for other communication to interrupt, and time and cost are reduced.

[Problems to be solved by the invention]

As described with reference to FIGS. 6 (a) and (c), the conventional communication method of the broadcast message shown in FIG. 6 (a) and turnaround polling for the transmission message shown in FIG.
