The separated position is a position where the print head is separated from the platen roller than the close position. The urging member urges the head unit and applies a pressing load pressing the print head against the platen roller. The eccentric cam rotates 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 adjustment mechanism adjusts a position of heating elements of the heat sink with respect to the platen roller by rotating of the eccentric cam.
