Abstract: A portable terminal device in which a case body performs sliding movement has had a problem that a groove may be exposed to the exterior when the case body is opened to a full extent of sliding amount, which will deteriorate grade of the portable terminal device and sealing ability of the case body, permitting dust or the like to enter the cases. In the portable terminal device according to the present invention in which a front side case is adapted to slide with respect to a back side case, a protruding member in a substantially T-shape in cross section is provided on the front side case, and a guide groove frame is provided on the back side case so as to enclose the protruding member, and a track along which the protruding member is adapted to move is defined in the guide groove frame.

Abstract: Mobile electronic equipment has a frame portion 8 which is formed in such a manner that the midsection of a side thereof is located at the longest distance from the surface of the liquid crystal display. Since the arched configuration can suppress deformation of the enclosure in comparison with the linear configuration as seen in arched structure of bridges, even when external pressure is applied onto the liquid crystal cover panel 2 or the enclosure cover 3, the enclosure cover 3, especially the midsection of the frame portion on that side resists deformation, and even when the frame portion of the enclosure cover or the liquid crystal display cover panel 2 comes in contact with the liquid crystal display due to deformation, a load applied onto the liquid crystal display upon contact may be reduced and cracks in the liquid crystal display may be prevented.
