Abstract

PURPOSE:To adjust nozzle pitch and ink jet direction in a uniform manner and at a prearranged precision by arranging an electric charge detection electrode stand having an indication circuit right after an electric charge electrode and stopping adjustment of a deflected ink jet direction when the indication circuit indicates a detected electric charge. CONSTITUTION:An electrode stand 1 equipped with a plural number of wire- shaped or bar-shaped electric charge detection electrodes 21, 22, 23... arranged in a deflection direction at a prearranged pitch, is installed right after an electric charge electrode. Electric charge detection circuits 51... are connected to the electric charge detection electrodes 21.... Indication circuits 71... are connected to the electric charge detection circuit 51.... Ink ejected from an ink jet nozzle 93 will be electrically charged and FET be closed instantaneously. Then pins 193, 203 will be turned so that an ink jet direction may be slided toward a deflection direction. If a luminous diode Dp1 becomes luminous, that signifies that ink particles collide with the lower surface (electrode surface) of wire 23 the ink ejection direction is appropriate.
