Abstract

PURPOSE:To enable to exchange the information softly, and elevate the operation rate in the double system, by providing a coupling part for changing an information transmission route in accordance with the operation state, on one of two coupled double systems. CONSTITUTION:A coupling part C is provided on the system A side, the coupling part C has a system C1 and a system C2, both of them are constituted so that sending and receiving the information to and from a system A1 and a system A2 of the system A can be switched, and the system C1 and the system C2 are coupled with a system B1 and a system B2, respectively. Also, the system C1 and the system C2 are constituted so that the information of a switching state can be sent and received mutually. In this way, the combination of each mode of the A and B systems can be coupled freely. That is to say, data are always transmitted to the system C1 and the system C2 from the system A1 and the system A2, and the system C1 and the system C2 transmit the data to the system B in accordance with the operation state of the system A1 and the system A2. In this way, the system B is able to continue its operation without considering the operation state of the system A.
