PURPOSE:To reduce the occurrence of noise having possibility of causing the malfunction of an electronic circuit by consisting a trigger means which allows a flash light discharge tube to emit light of a light emitting source and an optical generating body. CONSTITUTION:When a trigger switch 18 is turned on in a state where a main discharge capacitor 14 is charged to be ready to emit light, power is supplied to the light emitting sources 19a and 19b by a battery power source 11 in response to turning on the switch 18 so as to emit the light. Therefore, the optical generating body 20 to which the light is projected from the light emitting sources 19a and 19b generates high voltages and the flash light discharge tube 15 which receives the high voltage in an excitation electrode 16 becomes in a low impedance so as to emit the flash light by discharging the charged charges of the main discharge capacitor 14. Thus, the occurrence of noises which is the cause of the malfunction of the electronic driving circuit of a camera can be reduced. |
