Abstract: A printer includes a platen unit having a platen roller for advancing recording paper and a head unit detachably combined with the platen unit and having a thermal head with heating elements. A fixed blade is provided in the platen unit and a movable blade is provided in the head unit for undergoing sliding movement relative to the fixed blade to cut the recording paper. A detected member provided to the platen unit is positioned at a predetermined position of the head unit when the head unit is combined with the platen unit. The detected member engages the movable blade for movement therewith as the movable blade slides. A sensor is provided at the predetermined position of the head unit for detecting the detected member to detect that the movable blade is at an initial position and to detect a combined state between the head unit and the platen unit.

Abstract: A printing unit includes a thermal head, a platen roller, a head support member and a guide member. The platen roller is abutted against the thermal head with the recording sheet therebetween and rotated to feed the recording sheet. The head support member pivotably supports the thermal head around a pivot shaft so as to move the thermal head toward the platen roller. The head frame pivotably supports the head support member via the pivot shaft and rotatably supports the platen roller. The guide member guides the recording sheet between the thermal head and the platen roller. The thermal head and the guide member are positioned with respect to the head frame through the pivot shaft.
