ABSTRACT:
A thermal printer has detachably attached to a frame assembly of a printer a print unit having a built-in thermal head. The print unit accommodates therein an inked ribbon. By a drive member installed within the frame assembly, the thermal head is pressed against the platen roller and consequently driven thereby. The print unit is provided with a unit case and a cover allowed to be opened or shut relative to the unit case. The inked ribbon can be attached to or detached from the interior of the unit case. The unit is capable of incorporating the platen roller therein. In this case, the opening of the cover induces formation of an opening between the platen roller and the thermal head. The unit incorporating the platen roller therein is not required to be provided in the frame assembly thereof with the drive member which would cause the thermal head to be pressed against the platen roller by virtue of a spring member and and consequently induce a displacement of the thermal head. The use of a roll of thermosensitive recording paper in the unit obviates the necessity for the inked ribbon.
