摘要：A position control apparatus (optical apparatus) is disclosed which is capable ofpreventing disadvantages caused by the absence of a dead band while achieving arequired accuracy of positional control. The position control apparatus comprises a
controller which controls the drive of an object (optical member) so that the position ofthe object, which detected by a position detector, moves closer to a target position. Thecontroller has a control function which does not drive the object in a case where thedifference between the position detected by the position detector and the targetposition is within a predetermined range, and changes the predetermined rangeaccording to control modes relating to the drive of the object.
