To provide an ink sheet cartridge 20, to which a proper torque is given, without adjusting a torque on an image forming device main body side.

Three engaging bodies 52 are protrusively provided at one shaft part 48 with a flange 48a on the take-up side of an ink sheet 21. These engaging bodies 52 are inserted from inside into the axis hole 50 of one side plate 31a of a cartridge main body 30 so as to unwithdrawably engage with three fitting holes 53 in a first rotary member 46 with a transmission gear 47. Under the state that a tubular torque limiter 56 made of a member, the coefficient of friction of which is larger, is fitted to one predetermined end of a core tube 41 on the take-up side, the core tube is fitted through the inner diametral part 56a of the torque limiter 56 to the basic part 48a of the shaft part 48. When a torque larger than the limit torque value is applied to the ink sheet cartridge, a relative slippage develops at the place of the inner diametral part 56a.
