PURPOSE:To favorably apply a tension to an ink ribbon without damaging an ink-coated surface, by pressing an elastic member disposed near a payout-side reel against the back side of the ribbon by a columnar body, irrespective of the direction in which an ink ribbon cartridge is fitted to a main body of a printer. CONSTITUTION:A leaf spring 35 which applies a tension to an ink ribbon 39 when being pushed outward by a columnar body 66 is pressed against the back side of the ribbon 39. Therefore, the ink-coated face side of the ribbon will not make frictional contact with the spring 35, and the face side of the ribbon will never be damaged. When printing is again conducted by refitting an ink ribbon cartridge to a carriage 61 in the state of being inverted upside down or face side back after completion of a printing operation, a leaf spring 36 near a reel 38 on the ink ribbon payout side is pushed by the columnar body 66 of the carriage 61, and is pressed against the back side of the ribbon 39, whereby a tension is applied to the ribbon 39, and favorable printing is conducted without any slack of the ribbon. In this case, also, only the back side of the ribbon 39 is pressed, so that the ink-coated side of the ribbon is not damaged.
