Abstract
A thermal head is swingably supported by a shaft. Arm members are swingably attached to the shaft. The arm member presses a head base of the thermal head via a pressure spring. Above the arm members, cam disks are rotatably arranged. The cam disk presses the arm member toward the thermal head. When printing is performed on a color thermosensitive recording paper having a narrow width, the inside cam disks press the arm members to press the thermal head against the recording paper. When printing is performed on another recording paper having a broad width, all the cam disks press the arm members to press the thermal head against the recording paper.
