Abstract

PURPOSE: To realize a concealment facsimile system where only a specific receiver can receive information, by fluctuating the main scanning period of transmission signals to transmit them and by detecting fluctuation of the main scanning period to control the main scanning period of a receiver in the receiving side.
CONSTITUTION: The interval of main scanning synchronizing signals of facsimile transmission signals is made irregular or is fluctuated in respect to time to transmit them. In the receiving side, inputted facsimile signals are separated into picture signals 42a and synchronizing signals 42b by synchronizing separator circuit 42. Picture signals 42a are applied to switch 44, and clock pulse 46 is received to switch successively output terminals 45a∼45n in a fixed speed. Respective outputs of output terminal 45 are applied to recording needles, which are connected to the outputs above respectively, as recording signals. Meanwhile, synchronizing signals 42b are applied to clear terminal 44b of switch 44 after waveform shaping 43, and at this time, the output of switch 44 is immediately returned to output terminal 45a to switch successively output terminals 45b, 45c... again by the clock pulse.
