OBJECTIVE LENS DRIVING DEVICE, OPTICAL PICKUP DEVICE, AND DISK DRIVE DEVICE

PROBLEM TO BE SOLVED: To rotation-drive a lens holder holding an objective lens in a simple constitution. SOLUTION: A lens holder 2 is held to a movable block 3 with suspension wires 6a-6d. The movable block 3 is held by a trapezoidal spring member 4 having a leg 41 of a chevron-shape. A driving device 5 driving this movable block 3 is constituted of a two pole magnetized magnet 51 attached to the movable block 3, and a voice coil 52 opposing to this two pole magnetized magnet 51 and attached to a fixed base part 16. When power is fed to the voice coil 52, driving force moving the movable block 3 in the almost horizontal direction is generated, but the movable block 3 is rotation-operated by the deformation of the leg 41 of the trapezoidal spring member 4. Thereby, the lens holder 2 is rotation-operated, and an objective lens 7 is tilted. COPYRIGHT: (C)2005,JPO&NCIPI
