Abstract
Facsimile recording apparatus for electrically marking graphic signals line by line transversely of a recording web uses a scanning belt carrying styli which traverse a scan line along a recording zone through which the recording web is fed. The belt is composed of one or more sections each having identically spaced perforations or equivalent feed elements, and additional coupling perforations in the same predetermined relation to the feed elements in each section. By joining the belt sections with fasteners extending through the styli and coupling perforations of overlapping belt sections the styli are precisely positioned with respect to each other and to the feed perforations. The fasteners may also serve as signal conductors.
