PURPOSE:To make it possible to prevent a rubbing transfer phenomenon, by providing core receiving seats to an emitting side and a wind-up side in order to exclude sliding load caused by the winding disturbance of an ink ribbon and imparting viscosity resistance force to the slide surface of each receiving seat. CONSTITUTION:Even if the wind-up side ribbon 27 after transfer wound up by a ribbon wind-up core 37 is disturbed in an up-and-down direction by any cause, a core receiving seat part 40a is provided to a cassette case so as to prevent the contact of the ribbon end part 27a wound up in a disturbed state with the inner surfaces of cassette cases 39, 40. A core receiving seat part is similarly provided in an emitting side. Viscosity resistance 47 comprising grease is applied between the ribbon wind-up core 37 and the core receiving seat part 40a and the tension of the ribbon caused by the inertial thereof is reduced and the generation of a rubbing transfer phenomenon is prevented. By this method, the wasteful wind-up amount of the ink ribbon prior to head touch can be reduced and stable wind-up operation is enabled. |
