The main control unit is provided with a transfer arrangement for transferring a new control program to the terminal control unit through the transmission path. The terminal control unit is provided with a memory and a rewriting arrangement connected to the memory. The memory is for memorizing the first-mentioned control program as a memorized control program. The rewriting arrangement is for rewriting the memorized control program into the new control program at need.
