Abstract
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.
