摘要：
A flash device (10) for a photographic camera comprises a main capacitor (328); means for receiving a DC power source (311); a DC-DC converter (113-318) for boosting a DC voltage supplied from said DC power source to charge said main capacitor (328); a constant voltage supply means including a signal processing circuit (325) for transmitting and receiving a data signal between said flash device (10) and a photographic camera (11); a regulating means (322), connected for receiving said DC voltage supplied from said DC power source (311), for supplying DC power to said constant voltage supply means; a coil (T) coupled to an oscillation transformer (313) included in said DC-DC converter; and a smoothing capacitor (327) for smoothing an induction voltage in said coil caused by oscillation of said DC-DC converter, said smoothed voltage being applied to said regulating means (322) as an input voltage.
