Patent ID: 7716689

Claim:
A disk-storing disk device comprising a casing, the casing comprising: a driving unit comprising a rotational driving unit for rotating a disk; a plurality of supporting members operative to support a disk, the plurality of supporting members disposed in a stacked manner in an axial direction of the disk; a supporting member selecting mechanism operative to spread a spacing between a selected supporting member of the plurality of supporting members and another supporting member of the plurality of supporting members that is adjacent to the selected supporting member; a motive force transmission mechanism operative to move the driving unit from a retracted position away from a perimeter of a disk supported by one of the plurality of supporting members to an intervention position to clamp the disk supported by the one of the plurality of supporting members with the rotational driving unit; a transporting mechanism operative to transport a disk inserted from an insertion opening of the casing to the selected supporting member; a plurality of holding members movably supported by each of said supporting members, the plurality of holding members operative to hold a disk between the plurality of holding members and each of the supporting members when said supporting member selecting mechanism moves the plurality of supporting members in said axial direction of the disk; a holding switchover mechanism operative to move each of the plurality of holding members from a holding position for holding a disk to a holding disengaged position for disengaging the holding of the disk; wherein following a motive force of the motive force transmission mechanism moving the driving unit from the retracted position to the intervention position, the holding switchover mechanism is operated by a driving force of a driving source of the motive force transmission mechanism, whereby the plurality of holding members are moved from the holding position to the holding disengaged position; first and second side walls of the casing; and first and second holding switchover members for moving along the first and second side walls, the first and second holding switchover members being provided to the holding switchover mechanism; wherein a first holding member of the plurality of holding members is positioned to face the first side wall of the casing, and a second holding member of the plurality of holding members is positioned to face the second wall of the said casing; and wherein the first and second holding members are moved to the holding disengaged position by the first holding switchover member provided on the inner side of the first side wall and the second holding switchover member provided on the inner side of the second side wall.
