  • Patent number: 7665099
    Abstract: A loading device for a disk driver includes a transporting unit and a guide unit. The transporting unit includes one roller or two rollers, and the guide unit includes two symmetric or asymmetric cones. When loading a disc, two sides of the disc are individually supported on two cones of the guide unit. Two cones have different cone angles, equal cone angles but unequal lengths, or the same shape but different rotation velocities. The guide unit utilizes different arc speeds on two ends to obliquely convey the disc with any guide rails. The loading device reduces the cost of production and prevents the disc from generating collision and noisy.

  • Publication number: 20100035450
    Abstract: A docking station for a portable product is provided. The docking station has a body formed with an opening. A limiting block is formed on a bottom of the body to form a slide way. The limiting block and straight guide slots are on two opposite sides of the slide way. Through holes are formed around a connector in a docking cave. A slider of an ejection device on the slide way has oblique guide slots. A button is inserted into the opening to lean against an inclined surface of the slider. A push block is formed with a slide pin with two ends respectively inserted into the oblique and straight guide slots. A spring having both ends respectively pushing the body and fixed to the slider is for moving the slider to raise the button and locate the slide pin at a low end of the oblique guide slot.

  • Patent number: 7434236
    Abstract: A tray-type optical disc drive includes a base unit, an optical disc drive body, a front panel and a disc tray. The disc tray includes at least a retainer and a receiver. The receiver includes a horizontal bearing area, a ramp and a vertical bearing area. The ramp outwardly adjoins the horizontal bearing area while the vertical bearing area outwardly adjoins the ramp. The horizontal bearing area contacts with the outer edge of the disc when the disc is under horizontal disposition. The retainers are disposed on the receiver. When the disc is under vertical disposition, the retainers stop the disc edge for the disc to be positioned. The vertical bearing area and the retainer stop the lower edge of the disc edge. The upper edge of the disc edge leans against the horizontal bearing area.

  • Publication number: 20070288946
    Abstract: A method and apparatus for discriminating discs includes a loading mechanism transporting discs at an entrance of a disc drive. A sensor unit close to the loading mechanism starts or stops the loading mechanism according to the detection. The center of the receptor disposes a limiting pin to limit the moving distance of the receptor based on the disc size discriminated by the sensor unit. Two ends of a receptor dispose two symmetric positioning posts for positioning automatically. The disc size can be discriminated by counting sensors on for judging increases or decreases, and counting loading time for comparing with the predetermined time.

  • Publication number: 20070206467
    Abstract: A method for discriminating a disc includes the steps of: detecting that the disc is inserted into an optical drive; starting a roller motor to load the disc; counting the number of operating sensors; counting time of a disk loading procedure; judging whether all of the sensors operate to determine the disc is a primary disc; judging whether the number of the operating sensors decreases to determine the disc is a secondary disc; determining whether a disc loading time exceeds a default time by comparison; and ejecting the disc. If the number of operating sensors is kept the same as the original one and the time of the loading procedure does not exceed a default value, the method goes back to the judging steps to discriminate the disc repeatedly. If the disc loading time exceeds the default time, the disc is ejected.

  • Publication number: 20070134057
    Abstract: A pivot assembly for connecting a rotating body and a base includes a groove formed on the base, a support section formed on the rotating body, and two pivot bolts. The pivot bolts are inserted into a hole penetrating the support section from two sides of the support section respectively so as to cover a front end of each pivot bolt in the hole and expose a back end of each pivot bolt in a recess formed above the support section. The support section is inserted into the groove so that the hole corresponds to the cavity. Then, a plug is plugged into the recess to hold the back end of pivot bolts so that the pivot bolts can rotate smoothly in the cavities.
