Patent ID: 7221526

Claim:
A lens driving device comprising: a stator having a cylindrical shape, that generates a magnetic field therein; a rotor located within said stator and having a cylindrical shape which is coaxial with said stator, said rotor being rotation-driven by the magnetic field created by said stator; a lens holder located inside said rotor, that holds a plurality of lenses so that optical axes of the lenses are arranged along a center axis of said rotor, wherein a small lens of said plurality of lenses having a relatively smaller diameter than that of other of said plurality of lenses is located at an end of the arrangement of said plurality of lenses; a converting mechanism that converts a direction of force of rotation-driving of said rotor into a direction along the optical axes of the lenses and transmits the force to said lens holder; and a rotation stopper mechanism formed beside said small lens, that prevents a rotation of said lens holder.
