US 2003/0112718 A1 · Changer-type disk device

Abstract

A changer-type disk device includes a disk storage section holding disks arranged in the axial direction of the disks; a drive unit for reproducing and/or recording information from/in a disk selected from the disks in the disk storage section; a drive activating mechanism for moving the drive unit back and forth between a drive position where the selected disk is driven and a retracted position where no disk is driven; and pressing members. The pressing members come into pressure contact with the circumferential edges of the waiting disks held in the disk storage section to push them toward the disk storage section from the outside in the radial direction, and are separated therefrom when the drive unit is moved from the drive position to the retracted position. Accordingly, the waiting disks can be locked in the radial direction; thus, a rattle noise occurring from the waiting disks during driving of the selected disk can be reduced.

Dependent claims

A changer-type disk device comprising:

a disk storage section holding a plurality of disks arranged in the axial direction of the disks;
a drive unit for reproducing and/or recording information from/in a disk selected from the disks in the disk storage section;
a drive activating mechanism for moving the drive unit back and forth between a drive position where said selected disk is driven and a retracted position where no disk is driven;
and
a pressing member;
wherein
when said drive unit is moved to the drive position, said pressing member is brought into pressure contact with the circumferential edges of waiting disks other than said selected disk, which are held in said disk storage section;
and
said pressing member is separated from the circumferential edges of said waiting disks with the motion of said drive activating mechanism when said drive unit is moved from the drive position to the retracted position.

A changer-type disk device comprising:

a casing;
a face member having a loading slot through which disks are loaded into and ejected from the casing and arranged on the front of said casing;
a disk storage section arranged at the back of said casing for holding a plurality of disks arranged in the axial direction of the disks;
a disk transfer mechanism for transferring the disks between said loading slot and said disk storage section;
a drive unit movably arranged between said face member and said disk storage section for reproducing and/or recording information from/in a selected disk taken out from said disk storage section to a play position with said disk transfer mechanism;
a drive activating mechanism for moving the drive unit back and forth between a drive position where said selected disk taken out to said play position and a retracted position where no disk is driven;
and
a pressing member;
wherein
when said drive unit is moved to the drive position, said pressing member is brought into pressure contact with the circumferential edges of waiting disks other than said selected disk, which are held in said disk storage section, to press the waiting disks toward said disk storage section from the outside in the radial direction;
and
when said drive unit is moved from the drive position to the retracted position, said pressing member is separated from the circumferential edges of said waiting disks with the motion of said drive activating mechanism.
