ABSTRACT:
A drum-type transceiver facsimile machine having a plurality of light-to-electric transducers and a plurality of printing styli moved axially of the drum for scan/print operation. Shift register means and a buffer memory controlled by a programmed microprocessor provide for multiplexing of signals from the transducers having a scan operation and demultiplexing of signals during the print mode with use of a buffer memory permitting compression of the multiplexed signals and decompression of received signals prior to demultiplexing.
