<p><P>PROBLEM TO BE SOLVED: To provide an information processing apparatus capable of transmitting and receiving signals of a plurality of kinds of radio communication systems simultaneously through one cable. <P>SOLUTION: A mixing/distributing device 124 on the side of a computer body 11 converts transmitted signals of radio frequencies outputted from radio communication modules 126, 127, 128 to intermediate frequencies whose frequency bands do not overlap with one another, and mixes and outputs transmitted signals of those intermediate frequencies to one cable 301. A mixing/distributing device 123 on the side of a display unit 12 separates the mixed transmitted signals inputted from the cable 301, converts the separated transmitted signals of the intermediate frequencies to the original radio frequencies, and outputs the transmitted signals of the radio frequencies to corresponding antennas 1, 2 and 3. Received signals received by the antennas 1, 2 and 3 are also similarly mixed by the mixing/distributing device 123, and distributed by the mixing/distributing device 124 through the cable 301. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
