Abstract

PURPOSE:To obtain a high voltage stabilizing device to obtain the stable characteristic of a high voltage control by changing the input direct current voltage of a base ground direct current amplifying circuit with a variable resistor, eliminating the dispersion of the action point (conducting point of constant voltage Zener diode) of a high voltage stabilizing circuit and enlarging the change of a detected high voltage to the change of a beam current. CONSTITUTION:The voltage of an ABL terminal 16 of a flyback transformer FBT31 is inputted to the base of a transistor 14 for converting an impedance, and an emitter output voltage is inputted through a constant voltage Zener diode 10 and a variable resistor 30 to the emitter of a direct current voltage amplifying transistor 13. By using the variable resistor 30, setting is executed to the optimum action point of a high voltage control transistor. Thus, the fluctuation of the high voltage the change of a beam current can be suppressed to about half.
