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： An ink jet printer uses a planar thermoelastic bend actuator to eject ink from a nozzle chamber. The thermal actuator includes a lower planar surface constructed from a highly conductive material such as a semiconductor metal layer interconnected to an upper planar surface constructed from an electrically resistive material such as Indium Tin Oxide (ITO), such that, upon passing a current between the planar surfaces, the thermal actuator is caused to bend towards an ink ejection port so as to thereby cause ejection of ink from the ink ejection port. The actuator is attached to a substrate and further includes a stiff paddle portion which increases the degree of bending of the actuator near the point where it is attached to the substrate. The surfaces are further coated with a passivation material as required.

摘要： A curved print head is used for generating charged particles at a number of apertures and emitting those charged particles from the apertures to a cylindrical drum. The print head has a radius of curvature larger than the radius of curvature of the drum. The difference in the radius of curvature of the print head and the radius of curvature of the drum is limited by the variation in electric field strength deposited on the drum across the width of the print head.

摘要： The recording solution in a recording solution chamber is always pressurized. The shutter is closed when recording is not conducted to prevent the recording solution from flowing out and drying up. The shutter is opened by the shutter driving section in accordance with the image information during recording to open the extrusion opening. The recording solution is extruded from the extrusion opening by the pressurizing force. After the top end of the extruded recording solution is deposited to the opposed image support, the shutter driving section closes the shutter. This discontinues the recording solution flown so far continuously from the extrusion of opening to form a not-stringing recording droplet on the image support. Recording solutions having viscosity in a wide range can be used. The recording dots can be formed accurately with low energy, and high quality images with reduced blot of recording dots can be obtained at high speed.
