Claims

[Scope of utility model registration request]

A platen roller, a thermal head section provided with a line-shaped heating resistor, and a thermal head section provided in the thermal head section perpendicular to the line direction of the heating resistor of the thermal head section and corresponding to the left and right center portions thereof. It has a through hole and a shaft with a thread groove formed at the tip that is inserted into the through hole, and abutting and separating the thermal head portion from and against the platen roller.
a separating mechanism, a gimbal mechanism for bringing the line-shaped heating resistor of the thermal head into contact with the platen roller with uniform pressure, and a gimbal mechanism that penetrates the thermal head into the axis of the contact/separation mechanism. A biasing member that biases the thermal head toward the distal end of the shaft, and a biasing member that prevents the thermal head biased toward the distal end of the shaft from being removed from the shaft when A printer device comprising: a nut screwed into the thread groove of the shaft for the purpose of making a printer.
