Abstract
PURPOSE: To make high speed recording without recording noises possible, in an apparatus wherein a magnetic fluid is flown to a recording paper to perform recording, by providing an electrode for discharging the electric charge on the recording paper to restore quickly the voltage on the recording paper to the original state.
CONSTITUTION: Magnetic ink is supplied via a supply path 3 to a needle electrode 2, and high voltage pulses from a high voltage switching circuit 9 controlled by a needle electrode controlling circuit 10 are supplied to the needle electrode 2 to electrify the ink on the tip of the needle. High voltage pulses from a high voltage switching circuit 7 controlled by a picture signal controlling circuit 8 are applied to a gate electrode 1 thereby the ink on the needle tip is flown to perform recording on the recording paper 6. When the pulses are cut off, the voltage of the gate electrode 1 is decreased, and the electric charge on the recording paper is quickly discharged by a discharge electrode 14 in contact with the recording paper, so that that before the next picture signal the electric charge would not be accumulated, and therefore recording noises are prevented.
