<p>An actuator control device controls an actuator having an attached sensor, said actuator causing reciprocating motion of a movable section between a first drive end at which the detection sensor is attached, and a second drive end. Said device contains: a drive duration measurement section that measures a forward-path drive duration, being the duration from the start of the movement of the movable section toward the first drive end, until a detection signal is output by the detection sensor; an intermediate duration measurement section that moves the movable section positioned at the first drive end toward the second drive end, reverses the movement direction of the movable section at the point in time at which a first intermediate drive duration elapses, said first intermediate drive duration starting from the start of the movement of the movable section toward the second drive end, and measures a second intermediate drive duration starting from the reversal of the movement direction and lasting until the detection signal is output by the detection sensor; and a drive duration computation section that on the basis of the formula below, computes and outputs a return-path drive duration, being the duration needed for the movable section positioned at the first drive end to move to the second drive end. (Return-path drive duration) = (Forward-path drive duration) × (First intermediate drive duration) / (Second intermediate drive duration)</p> |
