A facsimile transmitter receiver system comprising a carrier having a read head and a write head movable linearly in both directions by a pulse motor for main scanning of a printing paper and an original paper, a control circuit for applying a predetermined number of pulses to said pulse motor for each main scanning cycle. A synchronization signal is generated in each scanning cycle in both the directions in the transmission mode, and said synchronization signal received by the corresponding facsimile system in the receiving mode initiates the operation of said control circuit, thus the facsimile systems in communication are synchronized to each other.

Facsimile transmitter receiver system

A linear scanning device for a facsimile system comprises a carrier which carries a write-head and a read-head, mounted on a belt which is moved in both directions by a pulse motor. Said read-head is composed of the end of a flexible optical fibre assembly having an emission fibre for illuminating a spot on an original paper and a receiving fibre for detecting the reflected brightness of a cell in said illuminated spot. Said optical fibre assembly is supported near each end of the same by a bearing, thus said read-head can move linearly in accordance with the movement of said carrier.
