ABSTRACT:
A facsimile system includes a transmitter having a light source, which provides pulses of light, scans an original copy. The pulses of light impinge on the copy during each scan. A light responsive device spacially related to the copy receives pulses of light from the copy in accordance with the copy, and provides electrical pulses. A circuit in the transmitter provides output signals in accordance with the electrical pulses from the device. A pulse source in the transmitter provides synchronization pulses. The system also includes a receiver which has a network receiving the output signals and the synchronization pulses. The network provides electrical data pulses in accordance with the received output signals and electrical synchronization pulses in accordance with the received synchronization pulses. A control circuit connected to the network provides a control signal in accordance with the data pulses from the network. A laser in the receiver scans light sensitive material and provides pulses of light which strike the material in accordance with the control signal. The receiver further includes apparatus for developing material so as to provide a printed copy of the original copy.
