Patent ID: 8701862

Claim:
A disk transportation device comprising: a pair of rotation arms that are rotatable respectively about a fulcrum shaft extending in the same direction as an axial direction of a center shaft of a disk-shaped recording medium on both sides thereof and that pinch a transportation passage of the disk-shaped recording medium transported between a disk changer where a plurality of the disk-shaped recording media can be stored and a disk drive device where recording or reproduction of an information signal with respect to the disk-shaped recording medium can be performed; and four transportation rollers of which two at a time are rotatably supported on the pair of rotation arms respectively, wherein the four transportation rollers contact an outer peripheral surface of the disk-shaped recording medium respectively and thereby the disk-shaped recording medium is held, and the pair of rotation arms are rotated in opposite directions to each other in a state, where one of the transportation rollers at a time is supported at the pair of rotation arms respectively, and contact the outer peripheral surface of the disk-shaped recording medium and thereby the disk-shaped recording medium is transported between the disk changer and the disk drive device.
