PURPOSE:To use a choke coil in common and to miniaturize it by providing a flash power source circuit which charges respective capacitors by desired time difference and on an identical cycle respectively and a trigger circuit which discharges respective flash lamps by the desired time difference and on the identical cycle corresponding to the charging cycles of the respective capacitors. CONSTITUTION:The terminals of the respective flash lamps 1a and 1b are respectively connected to one terminal of the choke coil 2 in common. Simultaneously, the respective capacitors 3a and 3b are connected between the other respective terminals of the flash lamps 1a and 1b and the other terminal of the choke coil 2. Then, the flash power source circuits 4a and 4b which charge the respective capacitors 3a and 3b by the desired time difference and on the identical cycle respectively and the trigger circuits 5a and 5b which discharge the respective flash lamps 1a and 1b by the desired time difference and on the identical cycle corresponding to the charging cycles of the respective capacitors 3a and 3b are provided. Therefore, the generation of heat can be restrained in comprison with the case that a current is made to flow to the choke coil 2 at the same time. Thus, the choke coil is used in common and miniaturized. |
