<p>PURPOSE:To attain a highly reliable system by removing fuzziness in the ON/ OFF of a power supply for a system having an automatic operation controller. CONSTITUTION:An automatic operation control part 1-d is provided with a system power supply monitoring circuit 2-b to monitor the existence of power supply to a system control part 1-g. Even when a power supply switch 1-j is turned on again after turning off it during the period of system operation, the generation of a trouble such as the restart of a power supply to a system body can be prevented. Thereby fuzziness in the ON/OFF of the power supply can be solved. Since a system clear signal is used as an interruption, a system state at the time of generating the clear signal can be monitored without erasing a condition set up immediately before the generation of the clear signal, so that the accuracy of control can be improved.</p> |
