Abstract
PURPOSE: To easily raise the processing accuracy of a head by a method wherein a needle electrode is arranged in an orifice provided in front of an ink chamber and the voltage of reverse polarity is impressed on an electrode arranged on the back side of recording paper, thereby an outputted picture of high quality and without shear of printing being surely obtained.
CONSTITUTION: An orifice 2 is made in front of an ink chamber 1, while a needle electrode 3 is provided in the center of the orifice 2 in such a manner that the pointed tip thereof is somewhat projected forward. Meanwhile, on an electrode 5 located on the back side of recording paper 4, provided in correspondence to a head part, is impressed the voltage of reverse polarity to the needle electrode 3. To the ink 7 positioned at the tip part of the needle electrode 3 are applied the force due to dielectric polarization and that due to indroduced change, thereby the ink at the tip part of the needle electrode 3 being turned to be particles and pulled to the side of the electrode 5 to fly, thus dot printing on the surface of the recording paper 4 being performed.
