LENS STRUCTURE HAVING FOCUSE CONTROL FUNCTIONAL

摘要

PURPOSE: A lens structure is provided to produce a moving motion and a stopping motion of a mover in which a lens is fixed by creating magnetic flux density bonding force and metal magnetic bonding force between the mover and a stator. CONSTITUTION: A lens structure(1) comprises a stator(10) and a mover(20). The stator forms an installation space(11). The mover is accepted in the installation space of the stator. A coil bundle(32) and a stopper(33) of ferromagnetic body material are arranged at one exterior of the mover. A shielding plate(12) of the ferromagnetic body material is formed at one inner wall of the stator. A permanent magnet(31) of an actuator member(30) is arranged in the inner wall of the shielding plate.
