Abstract:
A liquid droplet discharging apparatus includes: a first piezoelectric element that moves a head in a first direction; a second piezoelectric element that moves the head in a second direction opposite to the first direction; a movement unit that moves a medium in the first direction in accordance with a predetermined target movement amount; a transport amount measurement unit as a movement amount measurement unit that measures a movement amount of the medium in the first direction; and a drive control unit that controls driving of the first piezoelectric element and the second piezoelectric element. The drive control unit drives either one of the first piezoelectric element or the second piezoelectric element according to a difference B−A between a target transport amount A as the target movement amount and a transport amount B as the movement amount measured from the transport amount measurement unit.
