Abstract
A disk device includes a rotatable bar-shaped fixing element which is fixed loosely to an inner peripheral hole of each of a plurality of disks and a support element which forms a support section. The support section supports a section of a disk on a peripheral section of the fixing element. The support element is displaced in a direction of a rotational axis of the fixing element based on the rotations of the fixing element.
Claims31
A disk device comprising:
- a rotatable bar-shaped fixing means which forms a groove on an outer periphery and which is loosely fixed to an inner diameter of a disk;
- and
- a support means which abuts with a section of the surface of said disk, forms a support section which supports a section of said disk and forms a projection which engages to slide freely in said groove on an inner peripheral section and said projection slides in said groove and said support means is displaced in a direction of a rotational axis of said disk in response to rotations of said fixing means.
A disk device adapted to load a plurality of disks in said device is provided with a rotatable bar-shaped fixing means which forms a groove on an outer periphery and which is loosely fixed to an inner diameter of said plurality of disks and a plurality of support means which are provided on each disk, which abut with a section of the surface of said disk, which form respective support sections which support said disk and which form respective projections which are engaged to slide freely in said groove on an inner peripheral section and said projection slides in said groove and said plurality of support means is displaced in a direction of a rotational axis of said disk in response to rotations of said fixing means.
A disk device comprising:
- a disk loading mechanism including a rotatable bar-shaped fixing means which is loosely fixed to an inner peripheral hole of each of a plurality of disks, and a disk support means in which a support section for supporting a section of said disk is formed for each of said plurality of disks on a peripheral section of said fixing means, and said support means is displaced in a direction of a rotation shaft of said fixing means in response to the rotation of said fixing means, wherein the rotation shaft of said fixing means has a central axis perpendicular to a center of the inner peripheral hole of said plurality of disks;
- and
- a disk playing mechanism comprising a turntable and pickup, wherein when playing the disk a center of the turntable substantially matches the central axis of the rotation shaft of said fixing means in said disk loading mechanism.
A disk device comprising:
- a disk loading mechanism having a bar-shaped fixing means which holds a plurality of disks by loosely fixing with a hole formed in an inner diameter of a disk, to thereby displace said disk along the direction of a shaft of said fixing means by rotating this fixing means;
- a disk retaining mechanism for retaining a plurality of positions of an outer periphery of a disk to be played so that a shaft center of said fixing means can match substantially with the center of the inner diameter of the disk, at a position where said fixing means of this disk loading mechanism is divided;
- and
- a disk playing mechanism for playing and retaining said disk by moving from a predetermined standby position to a position of a disk retained by said disk retaining mechanism.
