  • Patent number: 5870358
    Abstract: A disk recording/reproducing apparatus has an improved structure such that a disk seated on a disk seating unit is inserted between rollers for transferring the disk to a magazine without a separate extracting lever between the rollers and the disk seating unit, thereby simplifying the structure. A tray position changing mechanism is provided which horizontally moves the tray, having the disk seating unit thereon, from a first position to a second position where the disk is inserted between the rollers.

  • Patent number: 5828645
    Abstract: A disk reproducing apparatus having a disk changing function is provided and includes a clutch mechanism for switching power to selectively drive a clamping mechanism for securing a selected disk and an elevating mechanism for lifting and lowering a stocker receiving a plurality of subtrays by using a single driving source. The clutch mechanism includes a motor installed on a main deck and having a motor gear, for generating power, a driving gear connected to the motor gear and which is rotated, a first connecting gear rotatably installed on the main deck and connected to the clamping mechanism, and a second connecting gear rotatably installed on the main deck, connected to the elevating mechanism, and located at a relative position lower than the first connecting gear.

  • Patent number: 5768247
    Abstract: A disk transferring device for transferring a disk to be extracted from and inserted into a magazine which can contain a plurality of disks and is built in a disk changer. In particular, the disk transferring device includes structure to suppress the hanging-down of the disk while transferring the disk. The disk transferring device of the disk changer can easily ensure that hanging down of the disk is suppressed since a pair of rollers for rotatingly transferring the disk is installed so that the rollers move relative to each other, to effectively support a rear portion of the disk being transferred.

  • Patent number: 5764616
    Abstract: A disk reproducing apparatus having a disk changing function is provided where non-selected disks can be exchanged with other disks which are not preloaded as a selected disk is being reproduced, and subtrays remaining on the upper side of a subtray transported from a stocker can be lifted. The lifting mechanism includes a fixing plate having a plurality of guide holes, positioned on the upper side of the stocker and fixed on first and second chassis members, a support plate slidably installed on the upper surface of the fixing plate and having a plurality of support pieces which are provided with support portions at the ends thereof, for supporting the subtrays, respectively, and combined with a plurality of guide holes, respectively, and a manipulating mechanism for transporting a support plate to move the support portions from a first position separated from the subtrays to a second position contacting the bottom surface of the subtrays.
