Abstract
PURPOSE:To achieve the prevention of false light emission and the common use of one end of synchronizing contacts and the earth of a strobe by performing the operation controlling of a trigger thyristor by the charged charges of a capacitor from the power source of a DC-DC converter circuit. CONSTITUTION:A capacitor 14 which becomes a kind of power source which performs the operation control of a trigger thyristor 5 is provided and the operation control of the thyristor 5 is performed by discharging through the synchronizing contact 4 of this capacitor 14, and therefore, one end of the synchronizing contact 4 and the earth (cathode side of a power source 3) of the strobe are connected and are constituted as a common line. In addition, the capacitor 14 is not charged by closing of the synchronizing contact and therefore the false emission of light owing to the operation of a power source switch 2 does not occur.
