Pickup device for a disk drive device |
摘要 |
A first adjusting base made of a leaf spring material is supported on a holder in such a manner that the first adjusting base crosses the moving direction of the holder and is slightly pivotable about a first pivot axis which is parallel to a disk surface. A second adjusting base made of a leaf spring material is supported on the first adjusting base in such a manner that the second adjusting base crosses the first pivot axis and is slightly pivotable about a second pivot axis. The first and second adjusting bases are biased in a slightly pivoting direction by their own elasticity and, by turning screws which restrict the biasing, the first and second bases are pivoted to adjust the direction of an optical axis of a pickup head. Shaking of the pickup head is prevented and shock to the pickup head is absorbed by elasticity of the first and second adjusting bases whereby the device can be made compact and light.
