    • 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. SOLUTION: A mixing/distributing device 124 on the side of a computer body 11 converts transmitted signals of radio frequencies output from radio communication modules 126, 127 and 128 respectively to signals of intermediate frequencies whose frequency bands do not overlap with one another, and mixes the transmitted signals of the intermediate frequencies to output them to the one cable 301. A mixing/distributing device 123 on the side of a display unit 123 separates the mixed transmitted signals input from the cable 301, converts the separated transmitted signals of the intermediate frequencies to signals of the original radio frequencies respectively, 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 similarly mixed by the mixing/distributing device 123, passed through the cable 301, and distributed by the mixing/distributing device 124.
