Abstract:
A disk device comprising:a stock unit in which multiple disk holders are arrayed in the direction of the thickness of a disk; a selecting unit for transferring said disk holders in said direction and transferring one of the disk holders to a selecting position; a rotational driving unit for clamping a disk; and a transporting unit for transporting a disk between a disk holder at the selecting position and said rotational driving unit, wherein said transporting unit comprises a pair of nipping members for nipping a disk held by a disk holder transferred to the selecting position by the outer edge of the disk so as to provide a transporting force to said disk, a spacing setting unit for changing the spacing between said nipping members, and a position changing unit for moving the position of said rotational driving unit; further comprising a control unit for performing operations wherein, prior to said selecting unit being operated so that a disk holder is transferred, said spacing setting unit is operated so that said nipping members are separated from the outer edge of a disk, and said position changing unit is operated so that said rotational driving unit is moved to a retracted position so as not to overlap with said disk held by said disk holder, and when one of said disk holders moves to said selection position and stops, (1) the spacing between said pair of nipping members is decreased so as to nip said disk, (2) following completion of the nipping, said rotational driving unit is moved to a driving position at which said rotational driving unit is overlapped with said disk held by said disk holder, and (3) said disk held by said disk holder at said selecting position is transported to a position at which said disk is clamped by said rotational driving unit by the transporting force of said nipping members.
