摘要： Travelling oscillation waves are generated in a lens assembly at an oscillation element by impressing a voltage to an electro-restriction element or elements, whereupon a lens driving operation is performed by frictionally driving a moving element which is pressed in contact with the oscillation element. In the case of manual operation, an oscillation ring operating as the oscillation element is separated from a rotation ring which constitutes the moving element by a clutch device and then the rotation ring is manually rotated for effecting the lens driving operation.

摘要： In a diaphragm device, a progressive oscillation wave is generated at a vibrating member by electrically energizing electrostriction members while a movable member which is arranged to actuate diaphragm blades is pressed into contact with the vibrating member by means of an urging member. The movable member is then frictionally driven by the oscillation wave to drive the diaphragm.

摘要： A lens mounting includes a movable cam having a cam portion formed to a convex shape, an axially movable member having a cam follower portion sliding on one of side surfaces of the convex cam portion of the cam in which a cam lift is formed. A lens is arranged to move axially in response to axial movement of the axially movable member, and a leaf spring pressing the other side surface of the convex cam portion urges the cam follower portion toward the one side surface of the convex cam portion. The leaf spring has its pressing portion at a position of the convex cam portion and is fixed to the axially movable member at a position displaced to a direction almost perpendicular to the optical axis from the pressing portion.
