PURPOSE: The reliability and the unit cost and noise performance are improved by reducing the number of signal wiring or the signal wire which the connecting apparatus for the multiple application instrument passes hinge. CONSTITUTION: An audio amplifier and processor(48) at least make A as an interface with microphone and speaker(46). According to a parallelizing unit(24) is the first cascade signal, the first parallel signal is outputted to the display device, the audio amplifier and processor. According to the serializing unit(22) is keypad, camera, and the second parallel signal from the audio amplifier and processor, the second serial signal is outputted.
