Abstract
A thermal printer has a thermal head mounted on a case main body and a platen roller confronting the thermal head. A cover member mounted to the case main body undergoes swinging movement to open and close an opening of the case main body. A slider rotatably supports the platen roller and is mounted to the cover member for linear movement on a plane including a rotational center of the platen roller and a swing center of the cover member. Engagement pieces mounted to the slider engage with engagement portions of the case main body when the cover member closes the opening of the case main body and the platen roller confronts the thermal head. A biasing member biases the slider such that the engagement pieces engage with the engagement portions of the case main body and the platen roller is brought into pressure contact with the thermal head.
