摘要： In a photographic camera provided with an electronic flash unit comprising a strobo lamp, the strobo lamp part is raised up and down by means of a small electric motor and gear link when the brightness of the object scenery is dark at a pressing of shutter release button to a midway position. The raising up of the strobo lamp part is automatically done by detection of the scenery brightness and switching on of the motor by an electronic circuit. When the strobo lamp part reaches the raised position, a limit switch causes the electronic switch circuit to stop the motor.
