Abstract
A transmitter for a facsimile system of run-length type, which comprises a facsimile signal generator, a pulse generator for producing a sampling pulse train, a sampler for sampling each of the space and mark signals with the sampling pulse train, and a coder for converting the sampled space and mark signals into successive binary code signals, the coder including at least two counters and means for selectively operating the two counters. A receiver for facsimile system of run-length type, which comprises a timing pulse generator for producing timing pulses, a demodulator for demodulating modulated binary code signals, a decoder for decoding the binary code signals into binary codes each representing a run-length of one of mark and space signals, a memory circuit for memorizing the binary codes, said memory circuit including at least two registers and means for selectively operating the two registers, and a reconverting circuit for reconverting the binary codes from the memory circuit into one of the mark and space signals.
