Abstract
In an actuating device for a lens assembly, the lens system of the assembly is mounted in a lens holding member which must be axially moved for focusing the lens assembly. In order to effect axial movement of the holding member, an operating member is fitted on the outer diameter of a cylindrical lens barrel of the assembly to be rotatable about the optical axis of the assembly, with the operating member having an inner peripheral surface wherein there is formed a cam recess for controlling the degree of axial movement of the lens holding member. A cam follower member mounted on the lens holding member is fitted in the cam recess of the operating member and rotative motion of the operating member is converted into axial motion of the lens holding member.
