Abstract
On a loading block LB, there are provided a wire 1 having spring properties and two rollers (disk pressing sections) 2 made of rubber that are capable of rotating about this wire 1 as their rotary shaft. One end of the wire 1 is coupled with a cam hole 4a provided in a large-diameter gear (rotary member) 4 of the loading block LB through a linking plate (operating member) 3 and a coupling pin 3a provided on this linking plate 3, so that the rollers 2 are subjected to drive control between a pressing position and a release position by the operation of this cam hole 4a. During disk feeding or clamping action, the disk D can be pressed against the disk holder DH by pressing the rollers 2 against the disk D.
