摘要： An objective lens driving apparatus having a lens holder, elastic supports, and a drive unit. The lens holds an objective lens. The elastic supports are secured at one end to the lens holder and at the other end to a fixed section, thereby allowing the lens holder to move. The drive unit drives the lens holder in a direction parallel to an optical axis of the objective lens and in a plane perpendicular to the direction parallel to the optical axis. The drive unit has at least two magnets provided on the lens holder, a coil section secured to the fixed section, and a yoke. The yoke constitutes, a closed magnetic circuit, along with the magnets. In the drive unit, said at least two magnets are arranged, opposing each other, the coil section is located in a gap between said at least two magnets, and a center of the gap is aligned with a center of the coil section.

摘要： This device has an optical pickup section, a first rack portion provided on the optical pickup section, a slide member having an opening/closing portion for opening/closing a facing surface of the objective lens to the optical disc and a second rack portion provided to be slidable on the first rack portion, and a driving mechanism having a driving gear which meshes with the first rack portion and the second rack portion. In this device, when the optical pickup section is moved to a predetermined position, the meshing state of the first rack portion with the driving gear is canceled and the second rack portion is driven by the driving gear to move the slide member, thereby moving the opening/closing portion from a position for opening the facing surface side of the objective lens to a position for closing the facing surface side.
