電装置。 A discharging device for a strobe inspection device for discharging and initializing the electric charge charged in a strobe light emission capacitor, in which a high voltage withstand voltage transistor for discharging and a load resistor are connected to the output side of the capacitor so as to be switchable. At the same time, a comparator is connected to compare the output voltage value from the capacitor with the set value, and when the output voltage value is higher than the set value, the charge in the capacitor is discharged through a high voltage transistor, and when it becomes lower than the set value. A discharge device in a strobe tester, wherein the switch is configured to be switchable so as to cause discharge through the load resistor.
