ABSTRACT:
A thermal printer includes a main frame having side plates, a platen roller rotatably supported in the main frame, a print head unit supported in the main unit so as to be pivotable between an image-forming state and a non-image forming state, a sheet case adapted to accommodate a sheet, and a contact portion that is attached to the print head unit so as to pivot together with the print head unit. The print head unit is pressed against the platen roller to convey a sheet therebetween when the print head unit is in the image-forming state. The sheet case is mounted in the main frame through an insertion part formed in one of the side plates. The contact portion contacts the sheet case from a second side plate side when the print head unit is in the image-forming state. It is possible to reduce the occurrence of printing defects.
