Abstract:
A flash light emitting device comprising:a capacitor; a flash light emitting tube; a charging circuit for charging light emitting energy into the capacitor by boosting a power supply voltage; a light emitting circuit for causing the flash light emitting tube to emit light using the light emitting energy of the capacitor; charging completion means for stopping charging of the capacitor when the charging circuit has performed a predetermined amount of charging to the capacitor; timer means for counting a lapsed time from a point of time that charging is stopped by the charging completion means; and charging control means for controlling charging such that until the lapsed time counted by the timer means reaches a predetermined value, recharging of the capacitor by the charging circuit is prohibited except for when a light emitting operation of the flash light emitting tube is started by the light emitting circuit when the recharging of the capacitor by the charging circuit is performed immediately after light emitting irrespective of the lapsed time counted by the timer means.
