Patent ID: 7716690

Claim:
A disk-storing disk device comprising a casing, the casing comprising: a plurality of supporting members which are operative to support a disk, the plurality of supporting members being disposed in a stacked manner in an axial direction of the disk; a supporting member selecting mechanism operative to move one of the plurality of supporting members to a selecting position; a driving unit comprising a rotational driving unit operative to clamp the disk when the disk is held by a selected supporting member members at the selecting position, and to rotationally drive the disk; a transporting mechanism operative to transport the disk when the disk is inserted from an insertion opening of the casing to the selected supporting member at the selecting position; a restriction guide member comprising a restriction face, the restriction guide member being turnably supported between a guide attitude and a non-acting attitude; and a transmission member operative to turn the restriction guide member; wherein, when the transporting mechanism transports the disk toward the selected supporting member at the selecting position, the restriction guide member assumes the guide attitude and faces the supporting member at the selecting position, and when the disk is transported between the selected supporting member at the selecting position and the restriction face, the supporting member selection mechanism moves the selected supporting member, the restriction guide member assumes the non-acting attitude and is retracted to a position where the restriction face does not overlap with the selected supporting member and the disk, and the selected supporting member supports the disk, wherein the restriction guide member is turnably supported by a face within the casing, the face facing an edge of at least one of the supporting members and extending along a direction of movement of the at least one of the supporting members, wherein when the restriction guide member assumes the guide attitude, the orientation of the restriction face is such that the restriction face is parallel with the face of a disk face of the disk supported by the supporting member at the selecting position and faces an edge of the disk, and when the restriction guide member assumes the non-acting attitude, the orientation of the restriction face is such that the restriction face is perpendicular to the disk face of the disk supported by the selected supporting member at the selecting position and is retracted to a position to not overlap with the disk.
