ABSTRACT:
A facsimile signal converter for mutually converting to each other one of a facsimile signal of one-way scanning and a facsimile signal of two-way scanning for each scanning line, in which a first read head and a second read head are reciprocated for scanning in opposite directions along two spaced but parallel travel paths, respectively, while a write head travels together with the first read head along a travel path developed at the midway between the two travel paths and to be positioned on the same line perpendicular to each of the two parallel travel lines. A recording medium is shifted by a certain length in a direction perpendicular to the travel paths for each scanning of the first read head and the second read head. In case of using an endless recording medium, it is alternately shifted by a first length and a second length twice the first length. Each of the certain length and the first length is equal to half the space between the two travel paths.
