Abstract
The present invention is applied to a device for driving optical component parts, such as an objective lens, in accordance with displacement of a disk. A mobile body, on which the optical component parts are mounted, is supported by at least two plate springs that are not parallel with the disk, in such a manner that the mobile body can be driven in a focusing direction and a tracking direction. The plate springs can have an electric wiring function so that no wires extend from the mobile body.
