Abstract
A pair of disk holders each having a groove for holding a periphery portion of an optical disk are provided. The disk holders are supported so as to be movable in a direction crossing the insertion direction of the optical disk. The disk holders are biased by a biasing member in such a direction as to make them approach each other. The disk holders are individually biased by biasing members in such a direction as to make them apart from the optical disk. When insertion of the optical disk is started, the optical disk is gripped by the pair of disk holders from its both sides, and then drawn into and carried to a disk chucking position by a disk loading mechanism.
