    • 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.
    • 在透光性鼓的整个外周面形成光电导层,在光电导层上形成导电层,并且由多个带状导电部构成。 提供在滚筒周围的是用于存储热熔油墨的罐,用于去除滚筒外周表面上的剩余油墨的刮刀,用于干燥填充导电层中的导电部分之间的间隙的油墨的干燥器, 它们用一张记录纸压在滚筒的外周表面上,与设置在滚筒内部的面对其内周表面的光源。 当根据图像信息选择性地操作光源时,使电流在图像记录区域中经由光电导层在导电层中的导电部分之间流动,从而使填充间隙的墨水被传送到记录纸。

    • 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.
    • 通过喷墨打印头,从所有孔喷射的墨滴适于具有均匀的尺寸具有以下结构。 由隔板分隔的多个墨室中的每一个都与一个具有第一过滤器的公共压力室连通。 公共压力室与普通的墨水供给路径连通,并插入第二个过滤器。 普通压力室和每个油墨室被压力室顶盖所覆盖。 在压力室天花板上,在对应于公共压力室的位置设置压电振动器。 与每个隔板对应地设置有弯曲并变形到增加体积的一侧的可动壁。 通过驱动压电振动器,在公共压力室中产生压力波,该波通过第一过滤器传送到每个墨室。 当可动壁弯曲变形时,吸收压力波,从而不会喷出墨滴。 当活动壁不变形时,由于压力波而喷射墨滴。

    • 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.
    • 喷墨头包括具有多个以规定间隔横向设置的孔的孔板,平行于孔板设置并通过垂直于偏振方向施加电位而变形的振动板,以及设置在孔板之间的多个隔板 和振动板在相邻孔之间的空间中,由孔,振动板和隔板包围的空间限定了要填充墨的压力室。 当施加信号电压时,振动板设置有在具有相对低的场强的区域中具有矩形横截面的凹槽。 在这种结构中,振动板的电容减小而不会不利地影响电场强度,并且振动板的变形效率增加。
