  • Publication number: 20120063072
    Abstract: A tilting hinge is disposed on a fixed housing and includes a rotating shaft, a bearing, and a movable piece. The rotating shaft includes a protrusion. Meanwhile, a lower half of the rotating shaft has a spiral curved surface. The bearing is provided with a spiral groove following the lower half of the rotating shaft, and the rotating shaft is biased toward the groove on the bearing by use of presser bar springs. Tilting of the movable housing causes the protrusion on the rotating shaft to slide on a surface of the groove on the bearing, and a rotation center of the rotating shaft to move upward.

  • Patent number: 7682170
    Abstract: The present invention relates to a cable wiring structure of an electronic apparatus that has such a movable unit as an opening/closing unit and a rotary unit. The cable wiring structure is provided to suppress the wearing of a cable to improve the durability of the cable, and to offer other advantages. The cable wiring structure applies to an electronic apparatus having movable units (hinge mechanism, rotation mechanism). The cable according to the structure has an extra length portion, which gives the cable a length necessary for the cable, for example, to pass through the movable units, and which is housed in a cable housing unit. The cable housing unit is formed on the electronic apparatus, where the cable housing unit arranges the extra length portion in a sinuous form and allows a shift in the extra length portion caused by a move of the movable unit.
