Abstract
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.
