Abstract: According to an aspect of the present invention, a thermal printer includes a housing in which a space is formed, printing means disposed in the housing, a cover disposed in the housing and which comes into contact with and separates from the housing when rotated, thereby opening and closing the space, urging means for urging the cover in a direction away from the housing, an engaging part which is disposed in the housing and which prevents the movement of the cover in a direction away from the housing when engaged with the cover, a pressed part which is disposed rotatably in the cover and which moves the engaging part when pressed, thereby releasing engagement between the cover and the engaging part, and elastic means arranged to urge the pressed part in a direction away from the engaging part.

Abstract: A thermal printer includes a first thermal head, a first platen roller, first biasing means, a second thermal head, a second platen roller, and second biasing means. The first thermal head, the first platen roller, the first biasing means are in contact with a heat-sensitive layer of thermal recording paper. The second thermal head, the second platen roller, and the second biasing means are in contact with a heat-sensitive layer of the thermal recording paper. The second thermal head is arranged on the upstream side of the first thermal head in a paper feed direction. A paper feed speed of the first platen roller to the thermal recording paper is larger than a paper feed speed of the second platen roller. The first platen roller is in contact with the thermal recording paper while being more slippery compared with the second platen roller.
