ABSTRACT:
A ribbon cassette used for both a fabric ribbon and a film ribbon has a first slit through which a fabric ribbon is passed and a second slit through which a film ribbon is passed, the slits being provided in a wall member which partitions a downstream end of a ribbon storage chamber for storing an endless ink ribbon in a meandering state. The second slit is disposed upwardly of the first slit, and a rib for applying a load to the travel of the fabric ribbon is formed on a bottom surface in the vicinity of the upstream side of the first slit at the same position as the second slit or downstream thereto. The second slit is provided at a position biased in a direction opposite to a projecting direction of the pull-out arm and the pull-in arm from the transversely central position of the ribbon storage chamber.
