利点がある。Next, when a phase OK signal indicating that synchronization for transmission and reception has been established is sent from the facsimile receivers 1 and 2 to the facsimile tonal control procedure circuits 9 and 10, the corresponding switches 7 and 8 are switched to the image signal 15. and notifies the facsimile image signal broadcasting device control circuit 14 that synchronization has been established with the facsimile receiver. Further, the image signal 15 sent out in this case is a white signal from the white signal generation circuit 12 selected by the image signal selection switch 11. Broadcast device control circuit 1 for facsimile image signals
4, if the synchronization of all facsimile receivers 1 and 2 is not completed by the time a certain period of time has elapsed, all the facsimile receivers are synchronized again at the time of timeout after the elapse of a certain period of time. If so, at the moment the image signal selection switch 11 is set to the image signal accumulation memo 1J13.
The image signals stored in the memory are simultaneously transmitted to all synchronized facsimile receivers. At this time, the control circuit 14 instructs the tonal control procedure circuit for the facsimile receiver that has not been synchronized by the timeout point to forcibly abandon the procedure, and the facsimile tonal control procedure circuit that has been instructed to do so Then, either disconnect the line at the line connection terminal or send an emergency stop signal to the facsimile receiver. As explained above, according to the present invention, there is no difference in the time it takes for each facsimile receiver connected to the broadcasting device for facsimile image signals to complete synchronization with the broadcasting device. If it is within a certain period of time, it can be covered by sending out a specific image signal (white signal in the embodiment) during that period, so a buffer memory is provided for facsimile receivers as in conventional devices. This has the advantage of simplifying the circuit configuration.
