<p>PROBLEM TO BE SOLVED: To prevent an over current from being inputted by providing a power source supplying part for impressing power supply to a DC load, door/lamp driving part for automatically opening and closing a door, and means for controlling ON/OFF only for an AC load. SOLUTION: In the state of inserting a power cord 100 into a power supply socket, the DC power source is always supplied through 1st and 2nd power source supply parts 122 and 123 to a microprocessor 121 and a motor/lamo driving part 124. When a pedal is pushed with a foot for opening or closing the door, the microprocessor 121 receives the transmission of door opening/ closing request, judges the current state of door later based on the information provided from open and close sensing sensors, turns the door motor 31 forward or backward and executes the operation for providing the state of door opposite to the current state. Then, the ordinary AC power source, whose phase is controlled, is supplied from an AC load driving part 125 to an AC load 103.</p> |
