Abstract: An optical disk device is capable of reducing a thickness of a loading portion equipped with plural sheets of trays. Trays installed in a main body are energized to put an optical disk between them in the thickness direction. Therefore, a thickness of plural sheets of trays can be reduced by cutting down a clearance between the tray and the optical disk. Also, plural sheets of trays are energized by spring members to be put elastically between them in the thickness direction. Therefore, an excessive pushing force is not applied to the optical disk loaded on the tray. Also, a hollow portion of the tray is formed such that projection portions protruded in excess of a standard thickness dimension of the optical disk do not interfere with the tray. Therefore, even when the projection portions are protruded from an adapter, such adapter can be loaded on the tray.

Abstract: Disclosed herein is a recording medium drive system including: a casing provided in a front face thereof with a slot through which to insert and discharge a recording medium having a principal surface and an opposite surface; and a sheet-formed member provided so as to close the slot and having a loop-formed deflected part which, while being deformed, is capable of making contact with at least one of the principal surface and the opposite surface of the recording medium at the times of insertion and discharge of the recording medium.

Abstract: A disk unit wherein a disk is inserted by a plurality of arms, the arms being able to convey two types of disks different in diameter while supporting an outer periphery edge of each of the disks. A disk is loaded to the interior of the disk unit by automatic loading, and a disk accommodated in the interior of the disk unit is unloaded to the exterior of the disk unit. The disk unit comprises a limit switch, the limit switch being actuated by an arm that is pressed by an outer periphery edge of a large diameter disk or a small diameter disk upon insertion of the disk from a slot of a bezel. The insertion of the large diameter disk or the small diameter disk is determined on the basis of the state of operation of the limit switch.

Abstract: A disc holder (16) rack and 2 moving disk drives (14). The disk holder (16) holds disks (18) from top via vacuum. The discs (18) get released by air entering the vacuum area, thus pushing the disc (18) down. The other part of the invention is the disc drive (14) that is mounted on a vertical drive mechanism (10, 46). By mounting the disc drive (14) directly on the vertical drive mechanism (10, 46), the intermediate transfer robot is eliminated. The drive mount(46) complies with the standard one in the computer industry, thus upgrading disc drives (14) is simplified.

Abstract: The invention includes a slot-in disk drive with a release device, wherein a side of a traverse is pivoted to a casing. A spindle motor disposed on the traverse rotates an optical disk with a non-data area. The release device is set on the traverse adjacent to the spindle motor. A first hole is formed on the traverse and located in a position corresponding to the non-data area. A release bar protrudes from a bottom of the casing for inserting into the first hole. A buffer is installed between the release bar and the traverse for isolating vibration.

Abstract: A disc apparatus includes a player and a holder. The player is configured for reading an optical disc, the player comprising a first latching portion. The holder is configured for holding extra optical discs, the holder comprising a second latching portion. The first latching portion and the second latching portion are capable of attaching the holder to the player cooperatively.

Abstract: A disc drive device includes a disc conveyance mechanism, a slide cam and a trigger slider. The disc conveyance mechanism has a cam driven element protruded on a movement route of the slide cam and a conveyance roller energized in a direction coming into pressure-contact with a disc by an elastic member. The slide cam has a cam contour part moving the conveyance roller in a direction being spaced apart from the disc against an elastic force of the elastic member while pressing the cam driven element. The cam contour part has a flat surface part formed in parallel to a moving direction of the slide cam, in order to move only the trigger slider, while restraining the slide cam by contact pressure of the cam driven element to stop the slide cam temporary, when conveying the disc inside a cabinet toward an aperture side of the cabinet.

Abstract: There is provided a disk apparatus having a clamp structure, which can fix a disk in a stable manner with a simple construction. More specifically, the disk apparatus includes a hub having a disk inserting portion having a cylindrical plane in the outer part of one end and a disk receiving portion having a flat part and being pivotably supported, a head having an inner hole through which the disk inserting portion is fitted, facing toward one face of a disk, levitating and scanning above the disk and reading a signal recorded on the disk or recording a signal on the disk, the disk being held by the disk receiving portion, and a clamp unit holding the disk with the disk receiving portion. In this case, the disk receiving portion has an inclined or declined plane. Thus, the amount and direction of deformation of the disk, which is caused by clamping, are defined, and obtaining a stable amount of head levitation independently of temperature changes can prevent the occurrence of a distortion of the disk.

Abstract: An optical disc device includes a budging mechanism, a transmission assembly, a disc holding down plate, and a lock gate structure. The budging mechanism is moved by mechanically interfering with the optical disc entering the working area of the optical disc device to drive the transmission assembly mounted on one side of the optical device so as to further operate the disc holding down plate and the lock gate structure. In such mechanical connections, the working timing of all the device and mechanisms can be controlled so as to drive the lock gate to open or close the loading slot in the right time.

The switch mechanism includes a plurality of switches, a rotary cam rotatable in ganged relation to angular movement of the turn arms, and a switch operating lever interposed between the rotary cam and the switches for successively pressing the switches in response to rotation of the rotary cam.

Abstract: A disk recording-and-reproducing device includes a box-like casing and a lid hinged to the casing to rotate about its pivot for opening and closing the casing. The lid has a disk holder and a swingable L-shaped lever both fixed to its rear side. The swingable lever has an upper flat shelf to support a disk when inserted in the disk holder. Also, the swingable lever has a rubber boss fixed to its lower end, thereby making the lever stand upright in parallel with a rear side of the lid when the lid is opened. On the other hand, the casing has a counter projection formed in confronting relation with the lower end of the lever, thus making the lever swing about its pivot apart from a lower end of the disk holder when the lid shuts.
