摘要： An inkjet recording apparatus includes K ejection electrodes and K gate electrodes corresponding to the K ejection electrodes, respectively, which are located at a distance from the K ejection electrodes. The K gate electrodes are divided into M blocks each having N gate electrodes electrically connected in common. A first voltage pulse is applied to a selected one of N groups each formed by electrically connecting an i.sup.th (1.ltoreq.i.ltoreq.N) ejection electrode for each block to each other and a second voltage pulse is applied to a selected one of the M blocks. A voltage difference is generated between a group and a block which are selected from the N groups and the M blocks depending on an input signal, wherein the voltage difference is equal to or greater than a minimum voltage difference which causes ejection of an ejection electrode.

摘要： In an electrostatic inkjet device having a plurality of ejection electrodes, when an ejection electrode is designated as an ejection dot, a potential of the ejection electrode is changed to an ejection level for a first time period. When the ejection electrode is not designated as an ejection dot, the potential of the ejection electrode is changed within a predetermined level different from a ground level such that ejection does not occur at the ejection electrode.

摘要： An electrostatic ink jet recorder of the type controlling charged toner particles contained in ink by using electrophoresis is disclosed. The recorder achieves a miniature and cost-effective configuration by reducing the number of drivers for driving ejection electrodes and auxiliary electrodes. The same amount of toner particles is ejected from all of ejection electrodes despite a scatter in the ejection electrode and a scatter in the position of the ejection electrode relative to auxiliary electrodes and a counter electrode.

摘要： A recording head includes an ink chamber storing ink containing electrified toner particles and having an ejection opening 7 at one end and an ejection electrodes for ejecting the toner particles from the ejection opening. A counter electrode 6 faces the ejection opening. The recording head also includes a toner, concentration detection sensor detects a potential of the ejection opening 7, and a control unit for deciding a detected toner concentration and controlling a voltage to be applied to the ejection electrodes. The surface potential nearby ejection opening or the toner concentration and a voltage applying time are made to previously correspond to each other and are stored in a ROM table. A stable printing quality is obtained by detecting the toner concentration near the ejection opening by the toner concentration detection circuit and controlling a voltage to be applied to the ejection electrodes corresponding to a detected value.

摘要： An electrostatic ink jet printing head includes a head block made of insulating material having a first surface and a second surface which are intercrossing substantially at a right angle. A plurality of ink channel grooves are formed on the first surface and the second surface in directions perpendicular to a ridge between the two surfaces. A plurality of recording electrodes are formed on convexities between the ink channel grooves and near ejection points located on the ridge. A cover is attached to the head block for covering the ink channel grooves and exposing the ejection points to the air. Ink is forcibly circulated by a forcible ink circulation means such as a pump. The recording electrodes are formed in the lower reaches of the ink stream compared to the ejection points, and a plurality of electrophoresis electrodes are formed in the ink channel grooves in the upper reaches of the ink stream compared to the ejection points. According to the electrostatic ink jet printing head, excessively higher concentration of the toner particles at the ejection points is prevented and stable ejection of the ink from each ejection point can be executed independently of history of ejection of each recording electrode, and stable ejection of the ink from definite and precise ejection points can be executed, thereby high precision clear printing is realized with a simple structure of the head and at a low cost.

摘要： The electrostatic ink-jet recording head according to the present invention comprises: recording electrodes which eject ink towards the recording paper; an opposing electrode for generating a prescribed electric field between the recording electrodes and the opposing electrode; and ink discharge end sections formed in the vicinity of the recording electrodes. The ink discharge end sections are formed closer to the opposing electrode than the end portions of the recording electrodes.In this case, the equipotential lines in the region of the ink discharge end sections when a recording voltage is applied are virtually perpendicular to the direction in which the ink is discharged. This is because, the recording electrodes are positioned slightly behind the ink discharge end sections in the ink discharge member. In this case, an electrostatic force acts on the toner particles near the ink discharge end sections in the direction of the ink discharge end sections. Therefore, even when a recording voltage is applied, there is a continuous supply of toner particles to the ink discharge end sections.As described above, in the electrostatic ink-jet recording head according to the present embodiment, a convex ink meniscus is formed in front of the recording electrodes. Therefore, toner particles gather at the discharge points, even when a recording voltage is applied, and thus a sufficient quantity of toner particles for forming a desired dot size can be supplied.

摘要翻译： 根据本发明的静电喷墨记录头包括：向记录纸喷射墨水的记录电极; 用于在记录电极和相对电极之间产生规定电场的相对电极; 以及在记录电极附近形成的排墨端部。 排墨端部比记录电极的端部更靠近对置电极。 在这种情况下，当施加记录电压时，在排墨端部区域中的等电位线实际上垂直于油墨排出的方向。 这是因为，记录电极位于墨排出部件的墨排出端部的后方。 在这种情况下，静电力作用于排墨端部附近的调色剂颗粒沿着排墨端部的方向。 因此，即使当施加记录电压时，连续向墨水排出端部供应调色剂颗粒。 如上所述，在根据本实施例的静电喷墨记录头中，在记录电极的前面形成凸起的墨水弯月面。 因此，即使施加记录电压，调色剂颗粒聚集在放电点，因此可以提供足够量的用于形成所需点尺寸的调色剂颗粒。
