UNIT FOR ADJUSTING LENS POSITION OF OPTICAL SYSTEM

摘要

PURPOSE: A position control unit of an optical system lens is provided to control the generation of a displacement motion by including a first shaft lens controller minimizing the volume of a lens cell. CONSTITUTION: A controller(40) forms a declined unit for motion conversion. A ring-shaped external flange(30) protects an optical system. A monolithic flexure hinge structure(10) comprises a lens mounting unit and a fixing unit. A fixing unit(14) is fixed and combined with the ring-shaped external flange. A top end flange unit which is extended is formed at the top end portion of a variant unit. The top end flange unit is supported to the declined unit of the controller. A rotary motion of the controller is changed into a top and bottom translation motion of the variant unit.
