Title: Ink ribbon cassette
Inventor: SAYAMA HARUO
IPC: B41J33/52
Filed: 1998-07-16
Abstract: PROBLEM TO BE SOLVED: To provide an ink ribbon cassette which can stably run a ribbon used in a thermal printer or the like, thereby maintaining a high print quality. SOLUTION: This ink ribbon cassette has ribbon slack prevention ribs 28. When the ink ribbon cassette is mounted to a thermal printer and printing is carried out, a ribbon is supplied from a ribbon pan cake 22 to a printing head 3. When each line is finished to be printed, the ribbon pan cake 22 having an inertia at the print time is braked by a resistance to the ribbon slack prevention ribs 28, so that a slack of the ribbon is restricted. A ridge of the ribbon slack prevention rib 28 in a radial direction of the ribbon pan cake 22 is chamfered and therefore a damage to an end face of the ribbon can be limited. Moreover, the ribbon slack prevention ribs 28 are disposed not to overlap with a ribbon take-out path of the ribbon pan cake 22, thus preventing a take-out tension from varying.
