Abstract: A disc device that performs insertion and ejection of a disc into and from a main unit by using a conveying roller includes a slider member for performing an operation of upwardly and downwardly moving the above-mentioned conveying roller, an operation of upwardly and downwardly moving an arm clamp for pressing the above-mentioned disc onto a turntable to hold the above-mentioned disc, and an operation of locking and unlocking a playback base on which the above-mentioned turntable is disposed. An engagement part for engaging with both an engagement part of the above-mentioned arm clamp and an engagement part of the above-mentioned playback base at a point is disposed in the above-mentioned slider member.

Abstract: A disk device including a first disk holder movable with disk conveyance, a second disk holder opposed to a groove portion formed in the first disk holder and holding a disk grippingly in cooperation with the first disk holder when the first disk holder holds the disk, and a supporter which supports the first disk holder and which causes a support position for the first disk holder to be shifted in accordance with the movement of the first disk holder to be shifted in accordance with movement of the first disk holder, realizes reducing in size and number of parts, prevention of damage to disks, shortening operation time for plurality of operations, improved vibration resistance and less expensive manufacturing cost.

Abstract: A disk device capable of storing a plurality of disks therein includes a disk holder capable of changing its vertical position to hold a disk, a driver to drive the disk holder, and the disk holder performs a rotational movement and the changing of its vertical height by means of the same driving mechanism of the driver. The disk device realizes a reduction in size and number of parts, prevention of damage to disks, a shortened operation time for a plurality of operations, improved vibration resistance, and a reduced manufacturing cost.

Abstract: A disk device realizing reducing in size and number of parts, prevention of damage to disks, shortening operation time for plurality of operations, improved vibration resistance and less expensive manufacturing cost is provided. The disk device capable of storing a plurality of disks includes an operation setting means to actuate the disk holding means according to an operation mode of the disk, and an operation mode switching means to switch the operation mode of the operation setting means based on contents of disk operation.

Abstract: A disk device realizing reducing in size and number of parts, prevention of damage to disks, shortening operation time for plurality operations, improved vibration resistance and less expensive manufacturing cost is provided. The disk device capable of storing a plurality of disks loosely fitted and supported at its inner diameter, including separable loose mandrel mechanisms, when the mandrel mechanism is loosely fitted to the disk, the disk holder holds the disk, and one end of the a second mandrel mechanism is connected to another end of a first mandrel mechanism in a state that the disk is raised to a height abutting upon a support of a ceiling side formed on the first mandrel mechanism.

Abstract: A disk device realizing reducing in size and number of parts, prevention of damage to disks, shortening operation time for plurality of operations, improved vibration resistance and less expensive manufacturing cost is provided. In the disk device when a disk is reproduced, a disk reproducing mechanism is moved to become a center of disk coincident with a center of turntable thereof, a first disk holding mechanism is moved downward to load the disk on the disk reproducing mechanism, then a disk clamping mechanism is moved to clamp the disk loaded on the disk reproducing mechanism, and the disk is reproduced after the first and second disk holding mechanism release the disk and are taken away from the disk.
