Abstract: A disc changer apparatus includes a casing. A plurality of trays are contained in the casing for carrying discs respectively. The trays are held and arranged in a stack. A region between a designated one of the trays and a tray immediately above the designated tray is expanded. A disc on the designated tray is pushed. A drive mechanism moves a turntable into the expanded region to place the turntable below the pushed disc. The drive mechanism includes a shaft, a base plate supported within the casing via the shaft, a damper, and a chassis connected to the base plate via the damper and carrying the turntable.

Abstract: Herein disclosed is a disc drive apparatus for driving an optical disc having a central portion formed with a central hole, comprising: a frame member, a disc retaining member rotatably supported by the frame member, a cam member supported by the disc retaining member and rockable with respect to the disc retaining member, a plurality of disc holding members each supported by the disc retaining member and operatively coupled with the cam member, each of the disc holding members being movable with respect to the disc retaining member to assume two different operation positions including a disc holding position in which each of the disc holding members is held in contact with the central portion of the optical disc, and a disc releasing position in which each of the disc holding members is held out of contact with the central portion of the optical disc, and a resilient member intervening between the disc retaining member and each of the disc holding members to have each of the disc holding members resiliently

Abstract: A disk recording/reproducing device includes a power transmitting mechanism which transmits movement of a pickup while engaging with the pickup, and a disk retaining mechanism which, in response to the movement of the pickup transmitted by the power transmitting mechanism, retains a disk on a turntable or releases retention of the disk. Radially inward movement of the pickup causes the disk retaining mechanism to retain the disk on the turntable, while radially outward movement of the pickup causes the disk retaining mechanism to release retention of the disk. For accomplishing the release of the retention of the disk upon the radially outward movement of the pickup, an operation switching mechanism is provided for changing a position of the power transmitting mechanism to cause the power transmitting mechanism to engage with the pickup upon the radially outward movement of the pickup.

Abstract: A disc changer apparatus includes a casing. A plurality of trays are contained in the casing for carrying discs respectively. The trays are held and arranged in a stack. A region between a designated one of the trays and a tray immediately above the designated tray is expanded. A disc on the designated tray is pushed. A region between the designated tray and the disc on the designated tray is expanded after the disc on the designated tray is pushed. A drive mechanism moves a turntable into the expanded region between the designated tray and the disc on the designated tray to place the turntable below the pushed disc. The drive mechanism includes a shaft, a base plate supported within the casing via the shaft, a damper, and a chassis connected to the base plate via the damper and carrying the turntable.
