Patent ID: 8090249

Claim:
A position controller for an optical element that is provided in an optical system, comprising: a movable member which holds said optical element, and is supported by a support member to be movable from an anti-shake driving range in which said optical element is positioned on an optical axis of said optical system to a removed position outside of said anti-shake driving range; an image-shake correction driver which drives said movable member and controls operations thereof within said anti-shake driving range in accordance with a magnitude and a direction of vibrations applied to said optical system; and an insertion/removal operational member which moves between an insertion position corresponding to said anti-shake driving range of said movable member and a removed holding position corresponding to said removed position of said movable member by a drive source different from said image-shake correction driver, wherein said insertion/removal operational member comprises: a first press portion which presses said movable member from said anti-shake driving range to said removed position by a movement of said insertion/removal operational member from said insertion position to said removed holding position; a second press portion which presses said movable member from said removed position to said anti-shake driving range by a movement of said insertion/removal operational member from said removed holding position to said insertion position; and a displacement prevention portion which allows said movable member to move within said anti-shake driving range and prevents said movable member from moving in at least one direction beyond said anti-shake driving range when said insertion/removal operational member is in said insertion position, wherein said first press portion, second press portion and displacement prevention portion together form said insertion/removal operational member as a single member.
