ABSTRACT:
An ink ribbon cassette with two projecting arms between which an ink ribbon is held exposed for printing. The cassette has a positioning slit in one of the arms, extended perpendicular to the running direction of the ink ribbon, and two side fixing projections. The former fixes the cassette in the running direction of the ribbon while the latter fix the cassette in the vertical direction, thus securing improved mounting of the cassette and preventing undesirable movement of the cassette.
