オートストロボにおける発光テスト装置。At least one of the strobe device or the camera used in combination with the strobe device has an automatic light adjustment means, and when the amount of emitted light reaches a predetermined amount of light after the discharge tube emits light due to discharge of the main capacitor, the discharging operation of the main capacitor is performed. In an auto-supporting electronic flash unit configured to interrupt and stop the light emission of the discharge tube, the light emission test signal generating means outputs a light emission test signal in response to operation of an externally operable light emission test button; means for receiving the light emission test signal and causing the discharge tube to emit light; and a light emission stop signal for outputting a light emission stop signal when a predetermined time set shorter than the time for the discharge tube to fully emit light has elapsed from the time of receiving the light emission test signal. A light emission test device for an auto strobe, comprising: a generating means; and a light emission stopping means for receiving the light emission stop signal and stopping the light emission of the discharge tube by interrupting discharge of the main capacitor.
