Claims

[Claims for Utility Model Registration] 1. A booster circuit that boosts electrical energy from a power supply unit;
A capacitor that stores boosted electrical energy, a flash tube that emits light by the electrical energy stored in the capacitor, a trigger circuit that starts the flash tube to emit light, and an output line from the booster circuit that connects the capacitor to the capacitor. and a wiring portion exposed on the circuit board that is a high-voltage output line leading to each input line of the flash tube and the trigger circuit;
The entire periphery or most of the wiring section is provided with a low voltage line, and the entire circumference or most of the wiring section is provided with a low voltage line, so that water that has entered the circuit board is necessarily electrically connected to the low voltage line before it travels on the circuit board and reaches the wiring section and the outside of the circuit board. An electronic flash light emitting device having an electric shock prevention device characterized in that a low voltage line is arranged so as to surround the electronic flash light emitting device. 2. Electric shock prevention according to claim 1 of the utility model registration claim, characterized in that the low-voltage line is arranged near the entire outer periphery of the wiring section of the high-voltage output line so as to surround most of the wiring section. An electronic flash light emitting device having a device. 3. Claim 1 of the utility model registration, characterized in that the low voltage line is arranged so as to surround the entire periphery of the wiring section of the high voltage output line.
An electronic flash light emitting device having an electric shock prevention device as described in 1.
