Abstract
A thermal printer with enhanced cutting performance includes a thermal head for performing printing on successively supplied recording sheets, and a platen roller for feeding the recording sheets. A cutter for cutting the recording sheets has a fixed blade and a movable blade. A main body unit supports the fixed blade, and a cover unit supports the movable blade and is removable with respect to the main body unit. A pinion gear meshes with a rack constructed integrally with the movable blade to move the movable blade. The main body unit supports the pinion gear, and the cover unit supports only the movable blade and the platen roller.
Claims18
A printer comprising:
- a main body unit which supports one of a thermal head and a platen roller and one of a movable blade constructed integrally with a rack and a fixed blade;
- a cover unit which supports another of the thermal head and the platen roller, and another of the movable blade and the fixed blade;
- and
- a movable blade drive mechanism for driving the movable blade and a platen drive mechanism for driving the platen roller, wherein:
- a pinion gear rotated by the movable blade drive mechanism is provided on a unit different from the unit supporting the movable blade;
- the cover unit is provided to be freely openable/closable with respect to the main body unit;
- and,
- when the cover unit is closed with respect to the main body unit, the pinion gear meshes with the rack and reciprocates the movable blade so that the movable blade and the fixed blade cooperate to cut a recording sheet at a predetermined position.
