Abstract

PURPOSE:To simplify the constitution of the control signal generating circuit of the transmitting side and the control signal detecting circuit of the receiving side each, by identifying the control signal which is sent to the receiving side from the transmitting side from the intermittent time of the modulating carrier and its periodicity. CONSTITUTION:Facsimile signal 5 received the analog modulation such as the amplitude modulation, the amplitude or phase modulation and the like is supplied to facsimile signal demodulating circuit 1. Then demodulated signal 6 is binary-coded through binary-coding circuit 2, and binary-coded signal 7 is sampled through sampling circuit 3. After this, binary digital signal 9 is sent to control circuit 4, and circuit 4 identifies various types of control signals as the picture signals based on the on/off of signal 9, its intermittence and periodicity plus the working sequence each. And at the same time, the types of the control signals are decided. Clock signal 8 is supplied from circuit 4, and circuit 3 delivers picture signal A in the form of binary-sampled facsimile signal 10.
