A disk device includes a disk rotation driving unitprovided movably in the direction of the Y axis to a chassisand immovably in the direction of the X axis thereto, a guide railsupported parallel to the X axis by the chassis, and an optical pickupsupported by the guide railand reciprocating in a radial direction of a disk which is rotation-driven by the disk rotation driving unit, wherein a positioning partperforming the positioning of a rotation center of the disk rotation driving unitby making contact with a rotor unitof the disk rotation driving unitis provided on the optical pickup

Disk device

A disc device is disposed to include contact parts which are relatively and respectively disposed in a roller base member and a slider member in such a way that a movement of the roller base member which receives the spring force of a pushing member to move a conveying roller to a disk conveying position causes a backward movement force to be applied to the slider member after engagement between a rack and a driving gear is released and a driving action of a cam part on the conveying roller is released while the slider member retracts to a disc insertion standby position.

Disc device

A disk device includes: a slider memberto be pushed and moved by the movement of a disk detection memberdetecting the loading of a disk when the diskis loaded in a predetermined position of a device body; a drive gearmoved in a thrust direction by the movement of the slider memberto be unmeshed from a rotation gearintegral with a conveyance roller; and a coil springthat normally urges the drive gearin a direction meshing with the rotation gear

Disk device for loading and unloading a disk with a conveyance roller

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.

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.

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.

Disk device holding a plurality of disks at its inner diameter

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.

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.
