Patent ID: 7024164

Claim:
A radio communication apparatus, comprising: a transmission section for transmitting an information signal; and a reception section for receiving the information signal transmitted from said transmission section; said transmission section and said reception section being attachable to each other and being detachable from each other; wherein said transmission section further comprises: a transmitter for modulating the information signal to generate a high frequency signal; a transmission antenna for wirelessly transmitting the high frequency signal; and an output terminal for outputting the information signal to said reception section via a non-wireless coupling; said reception section further comprises: a reception antenna for receiving the high frequency signal transmitted from said transmission antenna; a receiver for demodulating the high frequency signal received by said reception antenna to generate an information signal; and an input terminal to which the information signal outputted from said output terminal of said transmission section is inputted; at least one of said transmission section and said reception section further comprising: a sensor for sensing an attached condition between said transmission section and said reception section, wherein the sensed condition is determined by a location of an applied voltage; and a switch for selectively switching, in accordance with the sensed condition of attachment between the transmission section and the reception section, between wireless transmission and non-wireless transmission when communicating said information signal from said transmission section to said reception section.
