| 1. An inkjet recording apparatus comprising:
a head unit including:
an ultrasonic wave generation unit that generates ultrasonic waves;
an ultrasonic wave focus unit that focuses the ultrasonic waves to an ultrasonic wave focus position;
an ultrasonic wave transmission unit that propagates the ultrasonic waves from the ultrasonic wave focus unit; and
a wall plate that covers the ultrasonic wave generation unit, the ultrasonic wave focus unit and the ultrasonic wave transmission
unit;
an annular film that rotates while sliding along an exterior of the head unit;
a film drive mechanism that rotates the film; and
an ink application unit that applies ink over the film to form an ink layer,
wherein the ultrasonic wave focus position of the head unit is directing to a position of the ink layer so as to eject an
ink from the ink layer.
