PURPOSE:To simplify the operation for transmission/reception by coupling two bodies, a wrist watch section and a pocket section by infrared rays and performing transmission/reception from the pocket section. CONSTITUTION:When a buzzer 318 reporting an incoming call sounds, a carrier brings a mode button 308 to the radio equipment function made to attain the transmission state. A pocket section control signal is transmitted to an infrared ray transmission/reception section 317 of the pocket section from an infrared-ray transmission/reception section 309 of the wrist watch section and demodulated, a radio wave of 900MHz band for personal radio is modulated and the signal is transmitted from an antenna 316 to an opposite station as a personal radio wave. A personal radio wave transmitted from the opposite station is demodulated, then the result modulates an infrared ray and is outputted as the sound sent from a speaker 310 of the wrist watch section. |
