摘要： In an electrostatic acceleration type ink jet recording apparatus, when a voltage is preliminarily applied to ink to adjust the width of ink raises, a dedicated drive circuit has been necessary or dedicated electrodes have been necessary for forming the ink raises. According to a recording apparatus of the present invention, machining such as chamfering or steps is provided to a support body having a slit-like opening portion or, alternatively, a surface treatment such as coating an oil repellent solvent to a portion to be machined. Due to such a constitution, the width of the ink raises in the lateral direction of the opening portions can be made constant without using a method such as an electric driving so that a stable printing of dots is ensured. Further, by increasing the ink raise width in the vicinity of a central portion of the opening portion than at end portions of the opening portion, it becomes possible to prevent the diameter of dots to be printed from becoming non-uniform in the longitudinal direction of the opening portion.

摘要： There is provided a recording apparatus capable of outputting an image which is not provided with nonuniformity of printing, stable and provided with high quality by realizing a recording head for maintaining a shape of a meniscus of ink always in a proper state without carrying out highly accurate back pressure control. Hence, a shape of front ends of base plates forming a slit-like opening portion is constituted by a shape of a wedge directing a sharpened front portion thereof to a recorded medium. Further, an inclined face portion in the shape of the wedge is subjected to a water repellant or an oil repellant processing. Or, there is constructed a constitution of providing an ink discharge mechanism for discharging extra ink at an end face portion at outside of a printing area of the base plate constituting the slit-like opening portion.

摘要： In an ink jet recording head for an ink jet recording apparatus, insulating members are arranged between adjacent ones of a plurality of recording electrodes so that electric discharge is made less likely to occur across the recording electrodes. Thus, even where the density of the recording electrodes in the head is set high in order to achieve high resolution, ink can be stably jetted. Further, the ink can be supplied to the front end of the head without increasing a static pressure which acts on the ink in such a manner that the insulating members are disposed only in the vicinities of the front ends of the recording electrodes while the discharge withstand voltage across the adjacent recording electrodes is increased.

摘要： A print head has a reduced power size or increased print speed that can be operated at a lower voltage or higher speed and can maintain high-quality output printing free from thinned portions. During intervals between printing operations while a print paper is being fed, pulses are applied to all print electrodes to maintain a uniform potential difference between each of the print electrodes and a counter electrode so that an electric charge is supplied to the ink meniscus. Consequently, a sufficient Coulomb force to permit ink droplets to be ejected is obtained. Therefore, during printing operations, the supplied energy can be reduced and electric charge on the ink surface can be retained. Hence, ink droplets can be ejected stably without nonuniformities.
