Abstract

PURPOSE:To prevent the aggregation of printing charged drops with noncharged drops and increase the printing accuracy by applying a potential of equivalent polarity with that applied to a charge electrode to a deflecting electrode at the side where charged ink drops deflects, and rendering other deflecting electrode at a ground potential. CONSTITUTION:When a minus high potential is afforded to one electrode 4 of deflecting electrodes 4 and 4' and other electrode 4' is a rendered into a ground potential, an electric field formed by deflecting electrodes 4 and 4' and a shielding plate 9 acts to accelerate printing charged drops and decelerate noncharged drops. An insulating plate 8 in which a shielding plate is buried is provided between the charge electrode 3 and deflecting electrodes 4 and 4', and the charge electrode 3 and deflecting electrodes 4 and 4' are drawn near to each other without causing discharge to accelerate the deflection of printing charged drops.
