PURPOSE:To prevent a ink film from making its mistake setting when the ink film is exchanged, by a method wherein a first projection part engaged with a winding part which winds the ink film up is made higher then a second projection part engaged with a cutting part of a feed tube on which the film is wound. CONSTITUTION:In the case where a cutting part of an ink film winding side paper tube 9 is not engaged with a projection part of an ink film winding apparatus A4 when the ink film is exchanged, the ink film winding side paper tube 9 is fixed owing to back tension of the ink film 7. Then, the projection part 4a advances into the cutting part 9a by a force of a pressing spring 11, and a rotation force is transmitted to an ink film winding paper tube 9. The ink film starts to be wound thereby. Further, for an ink film feeding side, sliding occurs between an edge face D of an ink film feeding side paper tube 8 and a projection part until a cutting part 8a of the ink film feeding side paper tube 8 engages with the projection part 3a. After engagement, an initial marker 10 of the ink film is detected, and the ink film ends to be wound. |
