PURPOSE:To facilitate the stepping recording with good reproduction of the dripping liquid flow by controlling the dripping liquid quantity charging a special electric charge to the dripping liquid flow injecting between a discharging orifice and recording material. CONSTITUTION:A pressurized liquid 7 is fed to a nozzle 1 to inject it from a discharging orifice 2 and then forms a liquid dripping flow stretching forward. At this time, piezo-electric element and so on are preferably installed to the nozzle 1 and forcible vibration of the liquid column is effected through the mechanical vibration of the piezo-electric element. For example, when the signal to stepping display of one specified element is input to a voltage control means 4, voltage corresponding to the stepping mode is charged between an electrode 3 for the control of prescribed time and the liquid in such a way that the electric charge is charged to the group of the dripping liquid. Therefore, optional stepping mode can be displayed with good reproduction by effecting the electric modulation. |
