Abstract

PURPOSE:To surely operate the 1st and 2nd electric discharge tubes by so constituting the device that trigger pulses are applied nearly simultaneously to the 1st and 2nd discharge tubes. CONSTITUTION:When an electric power source switch 2 is turned ON, high voltage is generated in the secondary side coil 5c of a transformer 5, causing a neon tube 12 to light and charges to be charged in capacitors 16, 34 simultaneously. When a synchronizing switch 14 is turned ON in this state, a trigger pulse is generated on the high voltage side of a trigger coil 18, and an electric discharge tube 18 emits light 19. At the same instant when the trigger pulse is generated in the trigger coil 18 in this way, a trigger pulse is generated in a detecting coil 17 as well and the charges of the capacitor 34 are applied to a trigger transformer 35, by which a trigger pulse is generated, causing an electric discharge tube 36 to emit light nearly simultaneously with the discharge tube 19. Since in this way the device is so constituted that the trigger pulses are generated nearly simultaneously by the trigger coils 18, 35, the 1st and 2nd discharge tubes may be operated surely.
