  • Patent number: 7448054
    Abstract: An apparatus for clamping a disk comprises a clamper and a turntable. The clamper having a first cushion member is disposed on a bottom side of the clamper. The turntable is movably disposed relative to the clamper thereby clamping the disk between the turntable and the clamper. When the turntable is moved toward the bottom side of the clamper, one of the turntable and the disk touches the first cushion member first and then the clamper attaches to the turntable tightly for clamping the disk between the clamper and the turntable, therefore a striking force generated from the impact of one of the turntable and the disk on the clamper is reduced by the first cushion member.

  • Patent number: 7360224
    Abstract: A springing device including a moveable piece and an elastic object is provided. The moveable piece is disposed between the aperture and the tray and is able to swing. The first end of the moveable piece is pivotally connected to the internal of the casing and the pivotal connection is used as a supporting point of swinging, the second end of the moveable piece is pivotally connected to the baffler. The elastic object is connected to the moveable piece. When the tray is disposed within the optical disc drive, the elastic object sustains the moveable piece and the baffler, enabling the baffler to close the aperture. When the tray moves towards the aperture until touching the moveable piece, the moveable piece, which receives a force and swings, will apply a force onto the elastic object and move the baffler to slide, enabling the baffler to open the aperture.

  • Patent number: 6990673
    Abstract: A disc loading device for an optical disc drive that discriminates between standard sized optical discs and other objects. In the disc-loading device, two one-degree-of-freedom detecting arms are disposed near the slot of the optical disc drive. An edge sensor including an emitting component and a receiving component is disposed between two detecting arms. A control unit receives data from the detecting arms and the edge sensor when the edge sensor detects the periphery of an object inserted into the optical disc drive. The data is used to calculate the size of the inserted object. By comparing the measured size with the standard sizes of optical discs, the disc loading device can determine whether or not the inserted object is an optical disc or another object. If the control unit determines that the inserted object is not an optical disc, the object is unloaded.
