Abstract

PURPOSE:To enable to call out from the transmission side to the reception side without giving a failure to facsimile communication, by providing the callout signal generating means which inserts a callout signal to the boundary adjacent to a plurality of video signals corresponding to a plurality of scanning lines. CONSTITUTION:During facsimile communication, when callout such as emergent communication from the transmission to the reception side is made, a switch 31 provided at the transmission side is operated and the output signal from a signal oscillator 32 is fed to a pair of brushes 11 for switching with a slip ring 7. When this brush 11 contacts the conductor 9 of the ring 7, the callout signal is fed to an amplifier 18, the callout signal is inserted during the time band when the video signal is stopped with the brush 10 and it is transmitted to the reception side from the line T. Further, the video signal received at an amplifier 19 at the reception side and the callout signal are divided into two, the callout signal is fed to a brush 30 via a signal line 19, it is fed to an amplifier 33 via the conductor of a slip ring 26, and it is fed to a buzzer 36 via a callout signal receiver 35, allowing to call out the reception side from the transmission side.
