摘要:
A key switch device capable of preventing a key top from displacing in the horizontal direction when the key top is being depressed, and of minimizing wear and damage to the components thereof. A displacement restricting part, contacting each of a pair of link members, is formed by punching and bending a support plate. Further, on the back side of a trunk of each link member, an engaging portion capable of contacting the displacement restricting part is formed. When the key top is being depressed, the displacement restricting part always contacts the engaging portion, whereby the displacement of the link members in the horizontal direction or the slipping movement of the key top may be prevented.

An antenna apparatus is disclosed that includes a dielectric substrate, an antenna element pattern that is formed on an upper face of the dielectric substrate, a strip line that is formed on the upper face of the dielectric substrate and extends from the antenna element pattern, and a ground pattern that is formed on the upper face of the dielectric substrate and is arranged on either side of the strip line. The strip line, the ground pattern, and the substrate form a coplanar microwave transmission line.

An input device and a driving device able to be made thin and secure sufficiently large vibration amplitude are provided. The input device comprises an input panel, a current conducting element for conducting a driving current, and a magnetic field application unit for applying a magnetic field on the current conducting element. Both of the current conducting element and the magnetic field application unit are arranged in the peripheral region of the input panel. The magnetic field applied by the magnetic field application unit is parallel to the input panel and intersects the current conducting element. When the input panel is touched, a driving current is fed into the current conducting element, and a force is imposed on the current conducting element and the magnetic field application unit, making them move. This movement further drives the input panel to vibrate. Consequently, input operations can be recognized by feeling the vibration of the input panel.

The present invention relates to decoration techniques for providing smoothly changing iridescent color effects or glittering luster effects to resin casings. A thermoplastic resin casing having a protruding shape is fabricated by hot forming with a laminated plate made up of a thermoplastic resin plate and a polarizing film using a vacuum forming, an air-pressure forming, or a press forming technique. Alternatively, after forming a polarizing film in a mold having a prescribed shape, a thermoplastic resin is injected for molding, to produce a thermoplastic resin casing to which the polarizing film is firmly adhered. According to these fabrication methods, the polarizing film can be attached, without creases, over the entire surface of the casing.

A pointing device that can move an object in a desired direction on a display screen includes a control unit that switches between a first mode and a second mode in accordance with the contents of the display on the display screen. In the first mode, the pointing device outputs information as to the location of the object within a pointing area. In the second mode, the pointing device divides the pointing area into a plurality of areas and outputs information as to the divided area in which the object is located.
