To reduce the weight of a vibrator through a reduction in the weight and the size of a power source by connecting a voltage converting circuit and a voltage control circuit.

A boosting control circuit for a vibrator is provided which comprises a direct current booster circuit for converting the supply voltage from a small battery to direct current voltage of at least 3 volts or more and a high-voltage generating circuit for boosting the output from the direct current booster circuit to high voltage of at least 100 volts or more on the basis of the output from the direct current booster circuit. The high voltage generating circuit further comprises a variable pulse generating section that uses the output from the direct current booster circuit and a voltage converting section that uses the output from the direct current booster circuit as an input to an inductor. An output terminal of the inductor and a collector terminal of a transistor are connected, and the output from the variable pulse generating section is applied to the base of the transistor arranged in the voltage converting section. A condenser is arranged subsequent to the transistor.
