<p><P>PROBLEM TO BE SOLVED: To provide the shielding structure of a radio terminal shielding electromagnetic waves emitted from the inside while reducing a thickness, weight, and a cost, and being capable of maintaining structural strength as a whole. <P>SOLUTION: The key structure and the shielding structure of the radio terminal 1 have a substrate 11 in common with both the structures, electrical parts 16 mounted on the substrate 11, a bored shielding case 15 being fitted to the substrate 11 while surrounding the electrical parts 16 for shielding emitted electromagnetic waves and having an opening on the inside of a top face fitted to the substrate 11 and a key substrate 14 in which a key pad is disposed. The key structure and the shielding structure further have a key frame 12 mounted on the substrate 11 and supporting the key substrate 14 and a conductive sheet 13 secured between the periphery of the opening of the top face of the bored shielding case 15 and the underside of the key frame 12. The conductive sheet 13 is stuck to the rear side of the key frame 12, and a structure fast stuck to the bored shielding case 15 is formed, thus obtaining functions of the shielding case and the key frame by one sheet metal. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
