装置。 A rotary drive shaft that engages with a center hole located at the center of the disk, a turntable that is attached to this rotary drive shaft and rotates together with it, and a turntable that is slidable in the plane of the disk with respect to the turntable. A leaf spring that is supported and has an arm portion extending in a direction surrounding the rotational drive shaft, and is fixed to the arm portion of the leaf spring and provided at a position eccentric from the center of the disk through a through hole drilled in the turntable. What is claimed is: 1. A disk support device comprising: a drive pin that is engaged with a drive hole formed in the drive hole; and an elastic member that biases the leaf spring in a direction in which the drive pin moves away from the rotational drive shaft.
