PROBLEM TO BE SOLVED: To obtain a bobbin for an ink film in which oblique traveling of the ink film is prevented and travelling performance is enhanced while lessening the burden on a user at the time of replacing the ink film, and the cost of the ink film is reduced by decreasing the number of components thereof. SOLUTION: At the opposite end parts of a bobbin 12 for the feeding side ink film and a bobbin 13 for the winding side ink film having the same shape, guide shafts 12b and 13b being fitted in the flange parts 12a and 13a and the bearing parts 14a and 14b are formed integrally. Since the dimension L between the flange parts 12a and 13a is kept constant and the direction of the rotational axis of the guide shafts 12b and 13b is aligned constantly with the direction of the rotational axis of the bobbin 12 for the feeding side ink film and the bobbin 13 for the winding side ink film, travelling performance of the ink film can be enhanced. Furthermore, the number of components is decreased through integration formation and thereby the cost can be reduced. COPYRIGHT: (C)2004,JPO
