Abstract

PURPOSE:To reduce the number of wirings to improve the number of degrees of freedom of terminals, by multiplexing signals between the radio machine main body and man-machine interface terminals. CONSTITUTION:The signal from radio machine main body 13 to terminal machine 14 is digitized by coder 17 and control circuit 16 in radio machine main body 13 and is multiplexed by multiplexing circuit 19 and is transmitted to signal line 23, which is used as the signal line from terminal machine 14 to radio machine main body 13 in common, by time division transmission control circuit 21. In terminal machine 14, respective signals for receiver 28, power source display circuit 30, and so on are separated from one another by multiplexing separating circuit 25. The dial signal, the transmission signal, and so on in terminal machine 14 are multiplexed also and are transmitted to radio machine main body 13 through signal line 23. Consequently, the number of degrees of freedom of terminal machine 14 can be large even in a small car because only signal line 23 is required.
