Claims

[Scope of Claim for Utility Model Registration] The apparatus main body is equipped with a supply-side transfer paper rewinding mechanism including a motor that rotates a supply-side roll in a direction to wind up the transfer paper in order to locate the beginning of the transfer paper, and the above-mentioned supply A transfer paper cartridge having a side roll supported by a shaft having a gear and a take-up side roll supported by another shaft is attached to the apparatus main body with the gear engaged with the supply side transfer rewinding mechanism, and the platen roller In a thermal transfer printing device that performs thermal transfer printing on recording paper by pulling out the transfer paper from the supply roll according to the rotation of the gear, the transfer paper of the supply roll of the gear is placed between the gear and the shaft. A one-way clutch is provided, which is brought into an engaged state by rotation in the winding direction and transmits the rotation of the gear to the shaft, and which becomes disengaged by rotation of the gear in the opposite direction; . A thermal transfer printing device configured to cause the motor to rotate the gear in the opposite direction at a speed faster than the rotational speed of the shaft corresponding to the withdrawal of the transfer paper.
