PURPOSE:To reduce loss time even when there are many originals to be sent and to shorten the transmission time of all originals by eliminating the need for the transmission and reception of control signals between a transmitter and a receiver which are performed every time the transmission of one original is completed. CONSTITUTION:When a discrimination signal CED which indicates a nonvoice terminal and a digital discrimination signal DIS are sent from a reception side, a transmission side receives and detects those signals to send out a digital instruction signal DCS responding to a standard function discriminated by the signal DIS and a signal TCF for allowing a receiver to make a training check. The reception side detects those signals and confirms that there is no abnormality to send out a reception preparation completion signal CFR, and then a transmitter receives and detects it and starts sending a picture signal PIX. When the transmission of all originals is completed, a picture information end signal EOM is sent out and a signal MCF showing that the reception of additional picture from the reception side is possible is received and confirmed to send out a circuit disconnection instruction signal DCN to the reception side, disconnecting the circuit. |
