Therefore, maintenance of the printing apparatus 1 becomes easier.
- the transfer roller 36 includes an outer cover member 50 that covers the outer peripheral surface of the core member 49. Therefore, in this embodiment, if the outer cover member 50 to which the ink has been transferred is replaced, the transferred roller 36 can be reused. Therefore, in this embodiment, the running cost of the printing apparatus 1 can be reduced.
- the distance from the fourth lever portion 71d detected by the sensor 72 to the center of the fixed shaft 75 is fixed from the portion where the through hole 71f of the first lever portion 71a that engages with the roller holding portion 51 is formed.
- the distance to the center of the shaft 75 is longer. Therefore, even if the amount of change in the outer diameter of the transferred roller 36 that changes due to the transfer of the ink on the ink ribbon 3 is small (for example, about 0.5 mm), the outer surface of the transferred roller 36 is outside. A change in diameter can be detected with high accuracy by the sensor 72.

Therefore, in this embodiment, for example, even when the ink ribbon 3 is stuck to the transfer roller 36 and the winding torque of the ink ribbon 3 by the winding core 91 is increased, the winding 91 is between the winding core 91 and the transfer roller 36. It is possible to prevent the ink ribbon 3 from being broken. Further, in this embodiment, when the torque limiter 93 acts and the moving speed of the ink ribbon 3 wound around the core 91 becomes slow, the power of the ribbon feeding motor 27 is transmitted to the transfer roller 36 and the transfer roller. Since 36 feeds the ink ribbon 3 toward the core 91, even if the ink ribbon 3 is stuck to the transfer roller 36, the sticking of the ink ribbon 3 to the transfer roller 36 can be eliminated. .
