のサーマルヘッド装置。[Claims for Utility Model Registration] 1. Photographic paper is wound around the outer peripheral surface of a platen, and as the platen rotates, the thermal head is separated from the platen in a rotation range in which the end of the photographic paper faces the thermal head. The thermal head device is configured to print by pressing the thermal head against the platen in a rotation range from a printing start position to a printing end position of the photographic paper, the thermal head device having a rotating cam that rotates integrally with the platen. , a thermal head device characterized in that a cam surface of the rotating cam causes the thermal head to be separated from the platen when the platen comes to a rotation range in which an end of the photographic paper faces the thermal head. . 2 The thermal head is locked by the locking means in the spaced apart state, and the locking by the locking means is released by a solenoid when the platen reaches the printing start position, and the thermal head is pressed against the platen. A thermal head device according to claim 1, which is a utility model.
