PROBLEM TO BE SOLVED: To protect a head and a face of the user from an electromagnetic wave, especially a brain and eyes from the electromagnetic wave through shield from a transmission electromagnetic wave by adding an electromagnetic wave shield interposed between an antenna and the head of the user to a box. SOLUTION: A box 1 contains a digital system transmission reception circuit and has a transmission section and a reception section, and also a whip antenna 2 provided retractively and adopting vertical sliding type and a push dial 3. Then an electromagnetic wave shield plate 4 is interposed between a head of the user and the antenna 2 when the telephone set is in use to shield the brain and eyes from the electromagnetic wave. The electromagnetic wave shield plate 4 is fitted to a front side of the box 1 slidably vertically by a guide frame 41 and used for a cover of the dial 3 when the telephone set is not in used. Thus, the transmission electromagnetic wave radiated from the antenna 2 is prevented from acting on the brain and eyes of the user of the telephone set. |
