PURPOSE:To make the area of a printed board small and to reduce a cost by processing only by a circuit in a non-charge part without using the pulse of a charge part. CONSTITUTION:This blanking pulse generator uses only the circuit in the non- charge part without using the pulse in the charge part. A constant voltage power 3 obtained from the secondary winding of a flyback transformer 1 is divided, the pulse obtained from the secondary winding of the flyback transformer is applied to a capacitor 2, the divided voltage is synthesized with the pulse at the other end of the capacitor through a diode 6, thereby, the direct current voltage level of the pulse is raised and the rise of the pulse is made steep. Thereby, it is not necessary maintain an insulating distance between foils in designing a print pattern and the area of the printed board can be made small and the cost for parts can be reduced.
