Thermal printer
By using sensors to detect the contact status between the thermal printhead and the pressure roller and preventing printing when not locked, combined with the design of a lifter and a coil spring, the problem of poor printing caused by inappropriate contact force in thermal printers is solved, resulting in more reliable print quality and simplified operation.

Abstract
Embodiments of the present application relate to a thermal printer, and a thermal printer of the embodiments includes: a main body having a paper housing portion; an opening and closing cover; a printing portion having a platen roller and a thermal print head; an engaging portion engaging the opening and closing cover in a state in which the opening and closing cover closes the paper housing portion; a detection portion detecting a detected portion by a sensor to thereby detect a prescribed pressure-bonding state of the thermal print head and the platen roller; a printing control portion inhibiting printing in a case in which the prescribed pressure-bonding state is not detected by the detection portion; and a force applying member applying a force in a direction in which the main body and the opening and closing cover are mutually diverged in a state in which the opening and closing cover is not engaged to cause the sensor to not detect the detected portion.
