    Abstract: A platen roller is disposed opposite to a thermal head. In a head cleaning operation, a cleaning sheet rubs the vicinity area of a partial glaze, as pushed by the platen roller. Two types of bearings, a normal bearing with no eccentricity and an eccentric bearing, are attached to a rotary axis of the platen roller. The eccentric bearing is applied in the head cleaning operation. When the platen roller rotates, the rotary axis eccentrically rotates and reciprocates the platen roller in a vertical and a sub-scanning directions.
