Abstract
An image stabilized optical system includes a casing; an objective system and an eyepiece system; a gimbal which is connected to the casing via a shaft and is capable of oscillating; an erect prism attached to the gimbal; a motor attached to the gimbal; an inertial rotor supported by a rotating rod of the motor; an oscillating member attached to the gimbal; a caging member rotatably attached to the casing, the caging member being capable of moving between a caging position where the caging member prevents oscillation of the oscillating member and an uncaging position where the oscillating member is capable of oscillating; operating force-transmitting means for transmitting an operating force to the caging member; and an elastic member. The elastic member energizes the caging member at the caging position in a direction of pressing the caging member against the oscillating member, and energizes the caging member at the uncaging position in a direction of separating the caging member from the oscillating member. A caging mechanism is simplified and easily operated compared to a conventional one, and weight and cost reductions and easy handling of the image stabilized optical system can be attained.
