Patent ID: 7484229

Claim:
An optical pick-up comprising: a lens holder to which an object lens is attached, and to be moved in a focus direction in parallel to an optical axis of the object lens and in a tracking direction perpendicular to the optical axis of the object lens; a supporting block for movably supporting the lens holder in the focus direction and in the tracking direction; a supporting member formed of a bent or folded spring steel plate of uniform thickness to provide a pair of leg pieces for supporting and allowing the supporting block to be tilted by fixing front end sides of the leg pieces onto a base, the leg pieces being arranged such that spacing between the leg pieces increases as a distance from a side at which the supporting block is supported increases toward the front end side, the leg pieces including reinforcement portions whereby elastic deformation of the leg pieces is restrained; and a drive mechanism for applying a drive force to the supporting block so as to tilt the supporting block by changing the angular relationship of the pair of leg pieces, thereby tilting the lens holder which is supported by the supporting block.
