ABSTRACT:
A printer ribbon cartridge of the type employing two ribbon spools mounted in spaced relation in the cavity formed in the case of the cartridge. In this one, the ribbon is driven by a belt engaging the spools and, in turn, the belt is engaged by both of two alternately driven drive rollers. Alignment and guide devices keep the center lines of the ribbon and belt in coincident alignment and also keep the edges of the ribbon from frictional engagement with the top and bottom of the case.
