Abstract: A drainage system is provided for draining liquid accidentally spilled on a casing having a plurality of pushbuttons on a surface of the casing. An electronic apparatus may comprise a casing and a drainage system. The drainage system may be connected with the casing. The drainage system may include a liquid collecting basin, a drainage exit, and a liquid passageway. The liquid passageway may have a capillary surface and may lead the liquid from the liquid collecting basin to the drainage exit.

Abstract: The invention provides a casing structure for an electronic apparatus that achieves a thin size and light weight. The casing structure is capable of accommodating a display module, and comprises a sidewall and a bottom surface in which a conductive resin region and a nonconductive resin region are butt joined in a curved line. The casing structure of the electronic apparatus does not become thick due to the butt joining even when the joint portions are in a projection area of the display module. Furthermore, on the display side of the casing structure, there is no need to have special frame members for securing strength in addition to the display casing. The display casing accommodates and protects the display module from an external pressing force and also has a design function that the outer surface of the casing resembles that of an outer surface of a conventional notebook PC.

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.
