PURPOSE:To eliminate the production of a floating voltage at an output terminal of a high voltage power source by connecting a common oscillator to a power source line only when an input trigger pulse is applied and oscillating it. CONSTITUTION:When a negative trigger pulse is applied to one input terminal 1 of an OR circuit 24, switching transistors 26, 4 are simultaneously turned ON, an oscillator 2 and a control circuit 6 are simultaneously connected to a power source line L-L', and a high voltage is generated at an output terminal 2 through a high voltage generator 28. Similarly, when a negative trigger pulse is applied to the other input terminal 2 of the OR circuit 24, switching transistors 26, 8 are turned ON, the oscillator 2 and the control circuit 10 are simultaneously connected to the line L-L', and a high voltage is generated to the output terminal 1 through the circuit 26. |
