るインクジェット記録装置。An ink supply system that pressurizes ink to a constant pressure, an ink droplet generating section that applies ultrasonic vibration to the ink from the ink supply system to separate the ink droplets that fly at regular intervals and eject them, and the ink that is ejected during printing. Equipped with a charging electrode that applies an electric charge to the ink droplets, and a vertically opposed deflection plate that generates an electric field that deflects the charged ink droplets, it prints in the forward direction of the print head and in the multiple image direction. In an inkjet recording device, at least one of the deflection plates is two, and the two deflection plates are arranged symmetrically so as to form a predetermined angle, and the deflection plates are adjusted by inputting a signal in a feeding direction tM of the print head. A switching circuit is operated to apply a voltage to only one of the deflection plates, and means is provided to generate an electric field between the deflection plates facing each other, thereby adjusting the deflection angle of the ink droplets according to the feeding direction of the print head. An inkjet recording device characterized by being changeable.
