Patent ID: 7440201

Claim:
A lens driving device comprising: a moving body having a lens and a drive magnet that is moveable with the lens in an optical axis direction of the lens; and a fixed body that moveably supports the moving body in the optical axis direction, the fixed body including a first drive coil and a second drive coil that are disposed apart from each other in the optical axis direction so as to have a gap between the first drive coil and the second drive coil and form magnetic circuits with the drive magnet, and a first magnetic member and a second magnetic member that are disposed opposite the first drive coil and the second drive coil, respectively, wherein the drive magnet is disposed in the gap between the first drive coil and the second drive coil, and the drive magnet is moved in the optical axis direction to a first specified position which is nearer to the first drive coil and the first magnetic member or to a second specified position which is nearer to the second drive coil and the second magnetic member; and wherein the drive magnet is moved to the first specified position together with the moving body through energization of the first drive coil, and the moving body is retained at the first specified position by magnetic attraction working between the drive magnet and the first magnetic member after energization of the first drive coil is stopped.
