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.
Claims9
In graphic recording of electric signals on a web fed through a recording zone, means for scanning the zone comprising:
- a belt having a plurality of equally spaced feed elements between belt ends, and mutually registered coupling perforations at each end in predetermined relation to the equal feed element spacing,
- a signal marking stylus having apertures registerable with the belt coupling perforations, and
- means extending through the stylus apertures and coupling perforations for fastening the stylus to the belt and also joining the belt ends with the feed elements of the joined ends at the aforesaid equal feed element spacing and in predetermined relation to the stylus.
