PROBLEM TO BE SOLVED: To suppress axial oscillation and uneven rotation of an ink ribbon shaft, and to facilitate attachment and detachment of the ink ribbon shaft. SOLUTION: The printer 1 is a printer which performs printing to a recording paper while moving an ink ribbon to a head by rotatably driving the ink ribbon shaft 10 with the long ink ribbon wound in a roll shape. The printer comprises an ink ribbon cassette 5 which pivots the ink ribbon shaft 10 to freely rotate and supports the ink ribbon shaft to freely slide in the axial direction of the ink ribbon shaft, a driving part 30 which supports the ink ribbon cassette to freely slide and rotatably drives at least the ink ribbon shaft supported by the ink ribbon cassette, a moving mechanism 20 which moves by sliding the ink ribbon shaft in the axial direction of the ink ribbon shaft, a supporting part 3 which supports at least the driving part and the moving mechanism, and a case 5 which covers at least a part of the supporting part. The moving mechanism 20 moves by sliding the ink ribbon shaft in the axial direction by relative movement of the supporting part and the case. COPYRIGHT: (C)2008,JPO&INPIT
