Zusammenfassung:	PROBLEM TO BE SOLVED: To eliminate wasteful power consumption while an apparatus is not used and properly grasp the state whether a frequency heating apparatus is in use or out of use. SOLUTION: A control circuit 18 sets predetermined timer time based upon turning-on of a door switch 16 due to opening of a door and starts subtraction of the timer time based upon turning-off of a door switch 26 due to closing of the door, during which when a signal of a door switch circuit 26 and a signal of a key input circuit 23 are not inputted, it turns off a relay 17 when the timer time is over to interrupt power supply to the control circuit 18 and properly grasps use or non-use of a high frequency heating apparatus associated with the opening and closing operation of the door.
