Patent ID: 8121467

Claim:
A position controller for an optical element that is provided in an optical system, comprising: a first movable member supported by a support member to be movable relative to said support member in a first direction that is orthogonal to an optical axis of said optical system; a second movable member which holds said optical element and is supported by said first movable member to be movable relative to said first movable member in a second direction that is orthogonal to said optical axis and that is nonparallel to said first direction; an electromagnetic actuator including at least one magnet and at least one coil which are mounted to one and the other of said support member and said second movable member to produce a driving force for moving at least said second movable member in said second direction by passage of current through said coil within a magnetic field created by said magnet; and an insertion/removal driver that is directly connected to said second movable member and directly moves said second movable member in said second direction between an anti-shake driving position, at which a position control for said second movable member can be performed using said electromagnetic actuator, and a removed position at which said second movable member is positioned outside a range of said position control that uses said electromagnetic actuator.
