PROBLEM TO BE SOLVED: To provide an ink ribbon cartridge which is of such a compact constitution that a specified back tension is applied to a supply spool of an ink ribbon cartridge, and can be attached to/detached from an imaging device, and secures essential components so as not to allow them to fall. SOLUTION: This ink ribbon cartridge comprises a frame, a feeder shaft connecting member 39 and a take-up shaft connecting member 38. The frame is equipped with a first bearing member 50 and a second bearing member 4, and the feeder shaft connecting member 39 rotatively connects a feeder shaft with the first bearing member 50 and the second bearing member 40, while the take-up shaft connecting member 38 rotatively connects a take-up shaft with the first bearing member 50 and the second bearing member 40. The feeder shaft connecting member 39 revolves around a first shaft, while the take-up shaft connecting member 38 revolves around a second shaft. In addition, an interval between the first shaft and the second shaft is a specified value so that an appropriate amount of an ink ribbon 30 is exposed, and the imaging device using the ink ribbon cartridge is reduced in size.
