Abstract: A hinge which may be used for example in portable electronic devices may raise the upper body of the device from the lower body in response to rotation of the upper body about the hinge. The need to include a half-pipe section on the upper surface of the lower body maybe avoided. Thus more internal space of the lower body may be used without having to accommodate for the hinge. In an exemplary embodiment, the hinge may include a cam surface. The cam surface may be configured to shift a longitudinal axis of the hinge on response to the rotation of the upper body. In some embodiments, the shift of the longitudinal axis may be away from the lower body allowing a rear edge of the upper body to move across a rear edge of an upper surface of the lower body.

Abstract: The invention broadly contemplates an electronic apparatus that provides improved antenna characteristics, while maintaining a thin size and light weight. The electronic apparatus of the present invention includes a display casing having a nonconductive resin region and a conductive resin region in a bottom surface thereof; a display module accommodated in the display casing; an antenna disposed in the nonconductive resin region; and a system casing accommodating a wireless module connected to the antenna. By disposing the antenna in the nonconductive resin region formed in the bottom surface of the display casing, it is possible to secure high radio wave sensitivity while preventing an antenna mounting portion from being exposed to the outside of the display casing. The casing structure of the electronic apparatus does not become thick because of butt joining even when the joint portions are in a projection area of an LCD module.
