Abstract
Abstract A liner scanning device for a facsimile system comprises a carrier which carries a write head and a read head mounted on a belt w hich is moved linearly in both directions by a pulse motor. The read head is composed of the end of a flexible optical fiber assembly having an emission fiber for illuminating a spot on an original paper and a receiving fiber for detecting the reflected brightness of a cell in said illuminated spot. The write head is composed of the end of the other optical fiber one end of which is positioned at the output of a laser beam source, which heats a thermal printing paper selectively through the optical fiber. Thus the thermal printing paper is heated by a laser beam and the color of the paper is selectively changed according to the pattern to be printed.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
189 words
A facsimile scanning system comprising a carrier movable linearly in both directions, a flexible optical fiber assembly one end of which is supported at said carrier and the other end of which is pivotably fixed at a bearing, said flexible optical fiber assembly composing a read head for reading optical information on an original paper and a write head for printing a pattern on a thermal paper by the thermal printing principle, said read head having a plurality of thick emission fibers one end of which are positioned in front of a lamp and a thin receiving fiber one end of which is positioned in front of a photoelectric convertor, the other end of the receiving fiber receiving the reflected light beam from the original paper illuminated by the other end of said emission fiber, said write head having a long optical fiber one end of which is positioned at the output of a laser beam source generating a laser beam modulated by the pattern to be printed and the other end of which is positioned for scanning thermal printing paper for emitting said laser beam on that paper.
