  • Patent number: 8200300
    Abstract: A sliding electronic device includes a first component, a second component, a connecting element and a torsion element. The second component faces the first component. The connecting element is disposed between the first component and the second component, and has a first end and a second end, wherein the first end is rotatably disposed within the first component, and the second end is movably disposed within the second component. The torsion element connecting the first component to the connecting element is for providing torque to drive the connecting element. When a relative movement between the first component and the second component is generated under an applied force, the connecting element and the torsion element cause the second component to move between a close location and an open location on the first component.

  • Patent number: 7746626
    Abstract: A moving element having secondary keyboard for a portable electronic device is placed between a first member and a second member of the device for providing different keyboard sets to improve readability of text when in different operating configurations. When the second member slides out laterally relative to the first member, the moving element remains stayed in the first member, not moving with the second member. When the second member slides out vertically relative to the first member, the moving element slides with the second member along the sliding groove on the first member, and the moving element is exposed on top of the second member to present a concise dialing keyboard. The secondary keyboard contacts corresponding buttons of a primary keyboard directly. Thus, there is no need to provide additional circuit module exclusively for the secondary keyboard such that the cost and volume can be reduced.

  • Patent number: 7440150
    Abstract: A flatbed scanner includes a housing, a glass plate fixed to the housing, a front rib formed at a bottom face of a front part of the housing and extending downward, a back rib formed at a bottom face of the back part of the housing and extending downward, and side ribs formed at two sides of the housing and extending toward the center of the housing. The inner distance from the back rib to the front rib is not smaller than the length of the glass plate. The side ribs are under the bottom faces of the front part and the back part so as to form a fastening gap. Because the distance between the side ribs is smaller than the width of the glass plate, when the glass plate is inserted into the fastening gap, the glass plate is held.

  • Patent number: 7408684
    Abstract: A light source device capable of repressing light surges is fixed in a flatbed scanner to provide a light beam for scanning a document. The light source device includes a bent lamp with bent parts for generating the light beam and compensating for the brightness at two ends of the bent lamp; and a set of obscuring units fixed at the two bent parts to partially obscure the light of the lamp. Hence, the light source device can repress the light surge caused on two ends of the image sensor even if the bent parts at two ends of the lamp are very close to the sides of the scanning window. Therefore, the length of the light source device can be shortened and the width of the flatbed scanner using the light source device can also be narrowed.
