［産業上の利用分野］
本発明は記録装置に関し、特に直接記録媒体に記録する
静電式記録装置である。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a recording device, and particularly to an electrostatic recording device that directly records on a recording medium.

か大型化してしまうという欠点があった。[Problems to be Solved by the Invention] The former recording method using a photoreceptor has disadvantages such as a complicated device and lack of reliability. Another disadvantage is that the developing device and thus the apparatus become large in size because powdered toner as a recording agent is attached to the circumferential surface of the magnetic 1-1-ru and this is adsorbed onto the recording medium IJ to perform recording.

があった。In the latter type of inkjet recording, clogging may occur due to vibration caused by the pressure of the piezo vibrator, or air may enter the nozzle due to vibration of the nozzle.
There were problems such as 1 jamming, and there was an important drawback in reliability.
本発明の目的は静電気の吸引作用を利用して直接記録媒
体に記録を１−１う静電記録装置を提供することにある
。SUMMARY OF THE INVENTION An object of the present invention is to provide an electrostatic recording device that directly records information on a recording medium using the attraction effect of static electricity.

とする静電記録装置である。[Means for Solving the Problems] The present invention provides a charger for charging the recording medium on one side of the recording medium transport path, and a nozzle and the nozzle on the opposite side of the charger and the recording medium. This is an electrostatic recording device characterized in that a pair of electrodes facing each other is installed, and conductive ink is filled between the nozzle and the electrode.

電源７に接続しである。In FIG. 1, a charger 1 for charging a recording medium 2 is installed on one side of a conveyance path 8 on which the recording medium travels, and a nozzle 3
A power-saving recording head 6 consisting of a pair of a charger 1 and an electrode 5 facing the nozzle 3 is installed on the opposite side of the charger 1 and the recording medium 2. A conductive liquid ink 4 is filled between the nozzle 3 and the electrode 5, and the electrode 5 is connected to a power source 7 that generates a pulsed voltage.

ンク滴が形成されて記録媒体２に飛び記録される。In the embodiment, when a pulse voltage is applied to the electrode 5 of the conductive ink 4, a charge corresponding to the applied voltage is injected into the recording medium 2, and a charge opposite to the charge of the ink 4 is applied to the charger. Since the ink 4 is injected by the electric charge of the recording medium, ink droplets are formed from the holes 3a of the nozzle 3, and are splashed onto the recording medium 2 to be recorded.
