ABSTRACT:
A print head carriage assembly is provided which is especially suitable for use in a thermal dot matrix character printer. The assembly includes a belt, which in one embodiment is formed of laminations of film. The belt is formed into a loop with a free end by a tensioning device; the belt loop tautly passes around a pair of guides, one of which is bidirectionally rotatable to transport a print head clipped to the loop between the two guides and across a platen. The control signals to the print head are passed via conductors affixed to the belt from the free end of the belt to the print head.
