<p>PURPOSE:To make it possible to connect and disconnect a power supply without providing an independent controller to each compound system, by connecting a power controller to a single system and a compound system. CONSTITUTION:When either start or stop signal is inputted from receiver circuits 30 or 31, control circuit 33 operates to input a clock signal from originating circuit 32, and consequently control circuit 35 is operated to apply an output signal to drive circuit 36, so that circuit 36 will transfer a start or stop signal to a post-stage power controller. Then, switch SW1 assigning whether control is exercised by a single pair of start and stop signals or several pairs of start and stop signals is connected to control circuit 34: when an assignment signal is inputted from switch SW1, circuit 34 is actuated to stop the operation of circuit 35 and when assignment for several pair of start and stop signals is made, one of inputted start and stop signals is stopped, thereby interrupting the transmission of a signal outputted by circuit 36 corresponding to the signal. Then, control over the power connection and disconnection to and from the compound system is exercised.</p> |
