Abstract

PURPOSE:To decrease the probability of system down and the time, by automatically selecting the full state of the first unit in response to the control instruction at least from one of the first unit and other first unit. CONSTITUTION:The unit close signal and the unit release signal are outputted by the opposing interface circuit 17 of the first unit 9 from the unit waiting signal outputted from the unit status detection circuit 13 and the unit release close status signal from other first unit 10. Further, the unit status selection circuit 18 inputs the unit close signal outputted from the circuit 17 and the unit release signal to the circuit 13 to select the state of the unit 9 itself and outputs the unit release close status signal to the unit 10. Thus, in response to the control instruction from at least one of the units 9 and 10, the full state of the unit 9 is automatically selected to reduce the probability of system down and its time.
