  • Patent number: 7707596
    Abstract: A device and method for simultaneously manipulating multiple data storage cartridges or other storage elements in a storage library. The device housing includes an opening for receiving data storage cartridges. A gripping mechanism extends from the opening. The gripping mechanism is adapted to grip a data storage cartridge to be retrieved and to urge the data storage cartridge into the opening. One or more transport mechanisms are attached to one or more inner walls of the housing. The transport mechanisms are adapted such that once a data storage cartridge moves into the opening, the transport mechanisms will urge the data storage cartridge further into the opening until the data storage cartridge is held within the housing. The data storage cartridge can be moved further into the housing such that the gripping mechanism is free to collect additional cartridges.

  • Patent number: 7706360
    Abstract: An optical disk drive of a slot-in type is loadable with any of two optical disks different in the diameter, and has an insertion slot formed in a case chassis for disk loading. A disk entered through the insertion slot is received by a disk support arm set in a ready position. A loading mechanism is actuated when the disk support arm is pressed by the disk. In response to this, plural arms and the disk support arm cooperate to support the disk, which is moved to a chuck position for writing and reading information. For disk unloading, the disk, supported by the plural arms, is moved by the disk support arm to an ejection position. The disk support arm is shifted from an advance position for pressing the disk to the ejection position, to the ready position which is offset toward the chuck position.

  • Publication number: 20090300665
    Abstract: The disc device includes a casing, a drive unit, a disc processor swingably supported in the casing, and a first shift cam that swings the disc processor. The first shift cam restricts the swing of the disc processor to place the disc processor to each of an escape state, a clamp state, and a standby state. The standby state is a state in which the optical disc clamped to the turntable is allowed to keep a position apart from the opposing face of the casing while the disc processor is swung from the escape state to the clamp state. Accordingly, with no need to detect the position in the standby state with an arrangement such as separately-provided sensor, the disc processor can be placed in such a swinging state that the turntable can be controlled to be slightly rotated during the double clamp operation in a simplified arrangement. While preventing clamp failures, the optical disc can be favorably processed.

Further, the sliding plate functions to keep a positioning pin disposed on top surface of the holding rod in place, thereby causing the holding rods to be away from the optical disk when the optical disk reading device is in use.

  • Patent number: 7013471
    Abstract: The present invention relates to restrict a disk playing base plate against movement in back-and-forth directions, lateral directions and vertical directions relative to a housing by making use of the movement of a roller holder supporting a disk carrier roller. A pair of (i.e., left and right) side plates 11 of the roller holder has roller holder contact parts for restricting movement in the back-and-forth, lateral and vertical directions, and the top and bottom plates of the housing have housing contact parts corresponding to the roller holder contact parts. When a disk carrier roller is in a disk carrying position, the front part of the disk playing base plate is restricted against movement in the back-and-forth, lateral and vertical directions relative to the housing.

  • Patent number: 6963519
    Abstract: A disc device comprising a transfer unit operable to provide a transferring force to a disc inserted from the outside to transfer the disc into a storage area in the device, a sensor unit for detecting the position of the inserted disc, and a control unit for controlling a operational speed of the transfer unit. The control unit controls the operational speed of the transfer unit in the disc loading direction at a low-speed until the disc inserted from the outside reaches the transfer unit. The control unit then adjusts the operational speed of the transfer unit in the disc loading direction from a low-speed to a high-speed when the sensor unit detects that the disc is inserted into the position in which a transferring force from the transfer unit is given to the disc, or after a predetermined period of time has elapsed. Accordingly, the disc device reduces operation noise and resistance when the disc is inserted.

  • Patent number: 6941564
    Abstract: A disk insertion position setting device that can be compactly arranged. First and second sliding members 31 and 32, with disk contacting parts 39 and 41, are provided in a manner enabling sliding in directions that intersect a central line O of a disk insertion direction F. Sliding members 31 and 32 are urged by a spring 33 in directions in which disk contacting parts 39 and 41 approach central line O. A rotating member 34 is disposed in a rotatable manner between sliding members 31 and 32. By means of rotating member 34, the sliding of sliding members 31 and 32 in synchronization in mutually opposite directions is allowed and the sliding of just one of either sliding member 31 or 32 alone is restricted. A compact arrangement is realized by the use of sliding members 31 and 32 that slide in directions that intersect central line O.

  • Patent number: 6918127
    Abstract: A disk loading apparatus may include a first retaining device that is arranged in a slot for a disk to be inserted and thereby retains the outer edge of the disk so as to permit it to pass through the slot. A transferring device transfers the disk retained by the first retaining device to a predetermined position. A second retaining device is arranged in the interior from the slot and thereby retains the outer edge of the disk retained by the first retaining device and transferred by the transferring device. A rotating device rotates the disk at the predetermined position. Also, each of the first and second retaining devices has a contact section for contacting with the outer edge, upper surface, and lower surface of the disk in a slidable manner.

  • Patent number: 6826766
    Abstract: In a disk apparatus in which either a large-diameter disk or a small-diameter disk can be loaded, a pair of detecting projections and a pair of positioning projections are provided in a disk loading path, and a pair of selection grooves are formed in a chassis. Each of the selection grooves includes a first guide groove and a second guide groove. The positioning projections operate inside the first grooves when the opposing distance between the detecting projections is increased by a small-diameter disk, and they are pressed into the second guide grooves by the peripheral edge of the large-diameter disk when the opposing distance is increased by a large-diameter disk. The small-diameter disk is positioned by the positioning projections placed in the first guide grooves, and the large-diameter disk is positioned by the positioning projections placed in the second guide grooves.
