PURPOSE: A device for controlling a position of an insertable/separable image blur stabilizing optical element is provided to prevent damage to a shake prevention driving actuator caused by a flow of an excessive current to a coil at the same time with moving a shake-prevention driving frame. CONSTITUTION: A device for controlling a position of an insertable/separable image blur stabilizing optical element comprises a forward/backward frame, a main actuator, a shake prevention driving frame(18), a shake prevention driving actuator, an insertable/separable frame(20), a separation driving device, a controlling member, and an input member. The forward/backward frame moves between a photographing position and an accommodation position of a photographing optical system. The main actuator drives the forward/backward frame between the photographing position and the accommodation position. The shake-prevention driving frame is supported by the forward/backward frame to be moved toward a direction perpendicular to an optical axis. The shake-prevention driving actuator drive-controls the shake prevention driving frame with respect to the forward/backward within a plane perpendicular to the optical axis. The separation driving device is hung and fitted to the insertable/separable frame when the forward/backward frame moves from the photographing position to the accommodation position by the main actuator, thereby moving the insertable/separable frame from an insertion position to a separation position. The controlling member controls the operation of the shake-prevention driving actuator and the main actuator. The input member inputs accommodation command signals to the controlling member. |
