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。

摘要： A capacitance is detected between an ejecting electrode and an opposite electrode by a capacitance detecting circuit with a recording medium placed on the opposite electrode. An electric field strength in the ejecting electrode is calculated by a gap adjustment control circuit based upon the detected capacitance. A motor driving circuit is controlled so that the electric field strength is set to a preset value. A lead screw coupled to the ejecting electrode is rotated by a motor and a gap between the ejecting electrode and the opposite electrode is thereby adjusted. Even if the thickness of a used recording medium changes, the ejecting electric field strength is kept stable and the recording quality is stabilized.

摘要： An electrostatic ink jet recording device includes a recording head having an ink chamber receiving therein liquid ink containing electrified toner particles and a plurality of recording electrodes for ejecting the toner particles from the liquid ink. Each of the recording electrodes is applied with a bias pulse train when the recording head resides in a printing area and a non-printing area, and a selected group of the recording electrodes are applied with a constant recording signal for ejection of toner particles. Undesirable ejection of the toner particles in the non-printing area is avoided by the application of the bias pulse train.

摘要： A precision ejection ink-jet printing apparatus to prevent self-ejection. Self-ejection is an ejection of coloring agent particles from an ink-ejection opening without an application of ejection voltage to an ejection electrode. The precision ejection ink-jet printing apparatus includes an ink chamber filled with a pigment type ink, an electrophoretic electrode for causing coloring agent particles in the pigment type ink to concentrate at ink ejection openings, a plurality of ejection electrodes for causing ejection of the coloring agent particles concentrated at the ink ejection openings toward a printing medium, and voltage controller for controlling a voltage to be applied to the electrophoretic electrode. The voltage controller gradually increases the applied voltage up to a predetermined target voltage. The gradual increase in voltage moderates the electrophoretic motion of the coloring agent particles, preventing self-ejection.
