Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a power interruption detector which can secure the time for stabilizing a monitor when a power supply is interrupted. SOLUTION: This device is provided with an AC power supply full-wave rectification part 20, first voltage generation part 21, second voltage generation part 22, power interruption detection part 23, and microprocessor 24. The microprocessor 24 monitors the output voltage of the part 23 and stores the operation status data of the monitor during the activation power input when a constant output voltage is detected from the part 23. Thanks to such the stabilization for monitor, the readjustment of monitor usage status by an operator becomes unnecessary when a normal AC power AC is subjected to be inputted, and further the damage of a monitor itself due to that of a deflecting circuit can be prevented.
