PURPOSE:To obtain the captioned device capable of adjusting an ink jet direction in a uniform manner and at a prearranged precision through observation of an indication by providing an electrode stand formed with a plural number of microelectrodes at a prearranged pitch, an electric charge detection circuit connected to an electrode surface and an indication circuit which responds to a detection signal. CONSTITUTION:After closing FET instantaneously, a luminous diode Dp1 on a measurement operating board is watched while a screw 143 and pins 193, 203 are turned. The said diode will continue to be adjusted until it becomes luminous. If the luminous diode Dp1 becomes luminous, that signifies that ink has been ejected from a head 93 and ink particles electrically charged by the electric field of an electric charge electrode 9 have collided with the lower surface (electrode surface) of a wire 23, and the ink ejection direction is appropriate. |
