Abstract: A portable telephone to which additional function units, such as a flip unit and a slide unit, that provide additional functions for the main body of a portable telephone, are easily mounted on the case of a basic unit that includes only the essential units required for speech. One or more of an LCD bezel 40, a flip cover 50, a keypad bezel 60, grips 70, a keypad slide cover 80 and a slide cover 90, which are additional function units, are mounted on a basic unit 20. Therefore, this arrangement can cope with a request from a user who desires to alter a portable telephone he or she purchased to obtain a model he or she favors.

Abstract: A card connector includes a base member and two sets of contact members which are provided on the base member. One ends of the contact members serve as joining portions with respect to a circuit board of a portable telephone. The other ends of the contact members serve as contact portions with respect to a card. The joining portions are respectively disposed at mutually opposite ends of the base member. The contact portions are bent in a chevron shape and have terminations in a card fitting direction.

With such a construction, the BGA packages are prevented from being peeled off from the printed circuit board (13).

Abstract: Without housing a bare chip type liquid crystal driver within a package, to surely shield or absorb the light which reaches the liquid crystal driver so that erroneous display due to the photoelectric effect can be prevented. A light shielding tape 109 is affixed to the top surface of an upper panel 101 of a liquid crystal display panel 10 at an area which is opposite to the mounting area of a liquid crystal driver 107 mounted on the bottom surface of the upper panel 101. The light shielding tape 109 serves to shield the outer light incident on the liquid crystal driver 107. A diffusion sheet 40 composed of a light diffusing area 401 and a light absorbing area 402 located on the outer periphery thereof is arranged below the liquid display panel 10. The light diffusing area 401 serves to diffuse illumination light from a light source 202 to the liquid crystal display panel 10, and the light absorbing area 402 serves to absorb the extraneous light incident on the liquid crystal driver 107.

Abstract: The invention is to provide an antenna holding device, capable of achieving easy assembly and enlarging freedom in the assembling process. An antenna can be held by a screw so as to be mounted onto an antenna holder. The antenna holder is mounted onto a main body case by the outserting mount method. The main body case is provided with a groove, capable of holding an antenna terminal by itself. According to the configuration, freedom in the order of assembling process can be enlarged, and the process can be divided into smaller steps. Furthermore, operativity in assembly can be improved.

Abstract: A cover plate is attached to a switch portion of a coaxial connector. With this construction, even when the rising of flux due to surface tension occurs during a surface-mounting operation by reflow soldering, the flux is prevented from reaching the switch portion, thus preventing a disadvantage that the contact resistance is increased by the flux.
