a head unit configured to hold a heat sink to which is fixed a print head in which a plurality of heating elements is aligned in a first direction;
a head holding member configured to hold the head unit in a second direction intersecting the first direction;
a platen roller configured to rotate around a rotation shaft extending in the first direction;
a support shaft extending in the first direction and configured to support the head holding member to pivot between a close position and a separated position, the close position being a position where the print head is close to the platen roller, and the separated position being a position where the print head is separated from the platen roller further than the close position;
an urging member configured to urge the head unit and to apply a pressing load pressing the print head against the platen roller; and
an adjustment mechanism including an adjustment shaft and an eccentric cam and provided at the heat sink, at a position between the support shaft and an urging section in a third direction, the adjustment mechanism being configured to adjust a position of the heating elements with respect to the platen roller when the print head is at the close position, by the head unit moving relative to the head holding member as a result of rotation of the eccentric cam, the adjustment shaft protruding to a side of the head holding member and extending in the second direction, the eccentric cam being configured to rotate around the adjustment shaft and coming into contact with the head holding member in a state of being offset with respect to the adjustment shaft, the third direction being a direction intersecting the first direction and the second direction, and the urging section being a section urging the head unit, using the urging member.
