ABSTRACT:
The present invention provides a simple disk drive and drive unit driving mechanism with compact size in which each part is able to operate smoothly. The disk drive and drive unit driving mechanism comprise a disk holder10that has a plurality of holder plates11that individually hold disks D, a drive unit62that plays back disks D, disk selectors41A and41B that form a space above and below a desired disk D by raising and lowering the holder plates11, and a drive base60that moves the drive unit62into a space that is formed by raising and lowering the holder plates11. The disk selectors41A and41B are provided with flat cams41Aa to41Ac and41Ba to41Bc in which the protrusion14a provided on the holder plate11is inserted so as to be capable of performing a sliding movement, such that the tips of the cams are wedge-shaped. The holder plates11above and below the desired disk D rise and fall in accordance with the sliding movement of the disk selectors41A and41B.
