Abstract

See full text

There is provided a drive controller including a determination part that compares a target stop position of a movable body, which is driven by a piezoelectric actuator driven by a piezoelectric element expanded and contracted in response to an applied voltage, with a real position of the movable body acquired on the basis of a position sensor, and determines whether or not the target stop position matches with the real position, and a drive control part that turns off energization of the piezoelectric actuator when the target stop position matches with the real position while the movable body is being driven by the piezoelectric actuator.
