    摘要： A photoconductive layer is formed on the entire outer peripheral surface of a light transmissive drum, and a conductive layer is formed on the photoconductive layer and is made up of a plurality of strip-like conductive portions. Provided around the drum are a tank for storing thermo-melting ink, a blade which removes surplus ink on the outer peripheral surface of the drum, a drier for drying the ink filling the gaps between the conductive portions in the conductive layers, a platen roller which presses against the outer peripheral surface of the drum with a sheet of recording paper in between, and a light source which is provided inside the drum, facing the inner peripheral surface thereof. When the light source is selectively operated in accordance with image information, current is made to flow between the conductive portions in the conductive layer via the photoconductive layer at image recording areas, thus causing the ink filling the gap to be transferred to the recording paper.

    摘要： An ink jet print head by which ink droplet ejected from all orifices are adapted to have uniform size has the following structure. Each of a plurality of ink chambers divided by partitions is communicated with a common pressure chamber with a first filter interposed. Common pressure chamber is communicated with a common ink feed path with a second filter interposed. Common pressure chamber and each of the ink chambers are covered by a pressure chamber ceiling. On pressure chamber ceiling, a piezo vibrator is provided at a position corresponding to common pressure chamber. A movable wall which is bent and deformed to the side increasing the volume is provided corresponding to each partition. By driving a piezo vibrator, a pressure wave is generated in common pressure chamber, which wave is transmitted to each ink chamber through the first filter. When movable wall is bent and deformed, the pressure wave is absorbed, so that an ink droplet is not ejected. When movable wall is not deformed, ink droplet is ejected because of the pressure wave.

    摘要： An ink jet head includes an orifice plate having a plurality of orifices disposed transversely at prescribed intervals, a vibrating plate disposed parallel to orifice plate and deformed by applying a potential difference perpendicularly to the direction of polarization, and a plurality of partitions disposed between orifice plate and vibrating plate in the space between adjacent orifices, and the space surrounded by orifice, vibrating plate and partition defines a pressure chamber to be filled with ink. Vibrating plate is provided with a groove having a rectangular cross section in a region having relatively low field intensity when signal voltage is applied. In this structure, the electric capacitance of vibrating plate is reduced without adversely affecting the electric field intensity, and the efficiency of deformation of vibrating plate is increased.

    摘要： An ink jet head, having a long life, capable of discharging ink with a strong force and at a high speed is provided at a small size. A container comprises a casing and a nozzle plate covering the upper surface of the casing and an ink discharge opening. A buckling structure is fixed at its longitudinal ends to the bottom surface of the container via an installing member, and its center portion can be deformed upward by buckling. A diaphragm is positioned above the buckling structure with a space therebetween and placed on an inner wall of the casing with its periphery fixed thereto so as to liquid-tightly partition the inside of the container into a space and an ink chamber. A connection member connects the diaphragm and the buckling structure at their center. Electrodes are provided at both ends of the buckling structure to generate thermal stress therein by supplying electric current for buckling and consequently to apply pressure to ink in the ink chamber for discharging.

    摘要： A pressure generating member applies a pressure to an ink, the member having a symmetric configuration and including a buckling body. The buckling body may include a radially extending ribbed portion on its upper surface and no buckling layer beneath it. A heater layer is interposed between insulating layers for heating the buckling body, the buckling body having its peripheral edge portion fixed on a substrate. A center portion of the buckling body is buckled by being heated. An orifice plate is arranged so as to cover the pressure generating member with interposition of a gap defining a cavity for the ink. The orifice plate is provided with a nozzle serving as an ink discharge outlet located in a portion of the orifice plate opposite to the pressure generating member.

    摘要： An ink-jet head is provided with a container having an ink-discharge opening in its wall section; a structural element that has peripheral edges at least both ends in one direction of which are secured to the wall faces inside the container, that divides the inside of the container in a fluid-separated state, and that is allowed to be distorted; and a voltage-applying unit for applying a voltage to the structural element. The structural element is constituted of a piezoelectric material, and the shape of the structural element is changed in response to the voltage applied by the voltage-applying unit so that ink is allowed to discharge from the ink-discharge opening. Therefore, the above-mentioned arrangement makes it possible to provide a greater ink-discharging force and ink-discharging speed, while maintaining a small size of the head. Moreover, it is possible to provide an ink-jet head having a good discharging efficiency with long service life.
