Abstract: A printing unit includes a platen lock mechanism for switching between a locked state and an unlock state of the platen roller; and an urging member for urging the lock arm. The head unit has receiving grooves receiving the platen bearings through an opening. A lock arm presses the platen bearings when the operation lever is at the lock position, and is configured to allow disengagement of the platen bearings from the receiving groove through the opening by being swung from the lock position toward the unlock position side. The lock arm includes a pushing-up arm configured to push the platen bearings from the receiving groove toward the opening side along with movement of the operation lever from the lock position toward the unlock position. An urging member urges the lock arm toward the platen unit side.
