PURPOSE:To decrease both signal flux number and insulating circuit number by holding an interface part on the side of a second electronic instrument. CONSTITUTION:A signal transmitting line 5 is installed between a first electrinic instrument 1 and a second electronic instrument 4, signals between these both electronic instruments are transmitted with use of a time-division multiplex system. The first electronic instrument 1 is provided with a transmitting line signal connecting circuit to connect signals giving input and output tererinto to a signal transmitting line 5 with use of the time-division multiplex system. Further, the second electronic instrument 4 is provided with an interface part 2 to connect signals giving input and output thereinto to the signal transmitting line 5. The connection between the second electronic instrument 4 and the interface part 2 which ordinarily covers several thousands of pieces becomes wirings in the instrument, and it is dispensable with special insulating resistive force and drive circuitry at each input and output terminals of the interface part 2. |
