Abstract

In a facsimile transmitter in which original document information to be transmitted is photoelectrically converted to an analog video signal which is binary-coded through a binary-coder to be stored in a buffer memory, and the stored information is read from the buffer memory to be sent to transmission lines the transmitter is further provided with a transition detector for detecting the transition point of the binary-coded video signal read from the buffer memory, a run length signal generator for counting the number of pulses of a clock signal until the transition point of the binary-coded video signal is detected thereby to generate a run length signal, and a small computer for effecting the redundancy suppressing process on the basis of the binary-coded video signal and the run length signal.
