Claims

[Scope of utility model registration request]

A platen roller for winding photographic paper is rotatably fixed, and the platen roller is attached to both side walls of the platen roller so as to be movable back and forth in the direction of the rotation center of the platen roller. a clamping means that forms a photographic paper insertion gap between both ends of the body wall surface of the roller and presses against both ends of the body wall surface of the platen roller to grip the photographic paper when moved toward the rotation center of the platen roller; a clamp operation means that reciprocates the clamp means when operated; and a platen roller that rotates the platen roller so that when the platen roller is stopped, the photographic paper insertion gap is located at a predetermined position in the circumferential direction of the body wall surface of the platen roller. roller operation stopping means for stopping the rotation of the roller;
A photographic paper guide means for guiding photographic paper into a photographic paper insertion gap located at a predetermined position when the platen roller is stopped, a thermal head, and a thermal head that is supported and operated on the body wall surface of the platen roller. The head operating means is provided with a head operating means for press-contacting the clamp operating means, and an operating means consisting of a plurality of integrally formed cams for operating the head operating means and the clamp operating means, and the clamp operating means is operated by operating the operating means. a first state in which the thermal head is moved away from the platen roller by operating the clamping means to form a photographic paper insertion gap and separating the thermal head from the platen roller; and a first state in which the clamping means is inactivated and the thermal head is pressed against the platen roller body wall surface. and a third state in which the thermal head is separated from the platen roller body wall surface while maintaining the clamp operating means in an inoperative state.
