とを特徴とするインクリボンカセツト。 An ink ribbon cassette having a source core and a take-up core, and in which the ink ribbon wound around the source core is wound onto the take-up core through an exposed portion for printing, the ink ribbon being wound around the source core. a first back tension member that presses the ribbon; and a second back tension member that applies back tension to the ink ribbon by pressing the ink ribbon wound between the original winding core and the exposed portion with a constant force. and a back tension member, wherein the pressing force of the first back tension member gradually decreases as the ink ribbon on the source core is wound, and is released in the middle of winding. Set.
