PROBLEM TO BE SOLVED: To provide a printer device in which a thermal head does not easily fall out nor come off even if removing and dropping a spring for pressing a thermal head to a platen roller side.SOLUTION: In a printer device which has a printer head and a platen roller, and performs printing on recording paper which is sandwiched between the printer head and the platen roller, a protrusion is formed at a side part of the printer head, and a groove into which the protrusion intrudes is formed at a side face of a frame of the printer device. The groove comprises: a region in which an inlet of the groove is formed; a positioning region which is formed in a direction intersecting with a direction in which the region extends, and positions the protrusion; and an inclined part which is formed between the first region and the positioning region. In the inclined part, inclined faces which are formed in a direction in which the protrusion moves in the region and a direction which is different from the direction in which the protrusion moves in the positioning region are formed at an edge of the groove. |
