PROBLEM TO BE SOLVED: To meet a requirement for positioning multiple heads with high accuracy using a simple structure in a head unit where the multiple heads are aligned.SOLUTION: Each of multiple heads 1, where multiple nozzles for discharging droplets are aligned, is held by a first plate member 10, and the first plate member 10 is held by a second plate member 20. The second plate member 20 is held by an array base 40. The first plate member 10 may rotate around a Z axis, which is perpendicular to a nozzle surface of the head 1, relative to the second plate member 20. The second plate member 20 may rotate in an X axis direction, which is parallel with the nozzle surface of the head 1 and corresponds to a nozzle alignment direction, relative to the array base 40. |
