  • Publication number: 20080121721
    Abstract: A reflective reading structure with different optical paths switch for portable computer mainly takes a portable computer as main body, the front side of which a reading end is arranged and acted as an optical path for reading barcode. A securing column, respectively arranged at upper edge of two (light and right) sides of the reading end, is respectively pivoted to a long supporting frame, which has a turning function, and front side of which is finally pivoted a casting element that is corresponded to the reading end and has a turning function whereby, applying the reflecting function of the casting element and cooperating the turning function thereof, the light irradiated from the portable computer is reflected in order to scan barcodes at different positions.

  • Publication number: 20080110737
    Abstract: A trigger device includes a retaining frame, a swing arm, a toggle switch, a resilient member and a touch component. An end of the swing arm is connected to the middle of the retaining frame, and another end of the swing arm is connected to a magnetic sensor, and an end of the toggle switch is pivotally connected to the top of the retaining frame. The swing arm forms a pressing rod disposed on the toggle switch and pressed for swinging the swing arm. The retaining frame and swing arm are connected to the resilient member, and the touch component is mounted into the retaining frame and installed at another end of the toggle switch. An elastic button is installed between the touch component and the toggle switch for pressing the toggle switch. Obvious feel and tough can be provided to enhance the operability and convenience of the trigger device.

  • Patent number: 5790508
    Abstract: The present invention relates to a multidisk changer, which can be installed in a common CD-player, CD-ROM, LD-player or Video-CD player, comprising: a disk box, a curved slot plate, a disk selector, an optical pick-up, a linear slot plate, a box holder and a bottom plate. A plurality of disk trays can be placed in the disk box to store CD disks. Through the accommodation of the configurations of the curved slots of the curved slot plate and those of the linear slot of the linear slot plate, the disk selector and optical pick-up can be driven simultaneously by a disk selection motor to move sequentially to accomplish two actions: "disk selection" and "the up-and-down motion of the optical pick-up". In the meantime, to make use of a disk loading motor to accomplish the action of "disk loading and unloading". Since the present invention uses only two drive motors, it has the advantages of lower number of components used, lower cost, lower energy consumption, being simpler in design and easier in manufacturing.
