    • A liquid ejection head includes a plurality of orifices, a plurality of chambers in communication with the orifices, a plurality of fluid resistance portions in communication with the chambers, a plurality of liquid passages each including at least one of the chambers and at least one of the fluid resistance portions, a plurality of passage groups each including adjacent ones of the liquid passages, and a plurality of first partitions and a plurality of second partitions. The orifices eject droplets of liquid. The fluid resistance portions each are narrower than the chambers. Each of the first partitions, provided with a void, separates adjacent ones of the liquid passages. Each of the second partitions, which is not provided with the void, separates adjacent ones of the passage groups. The liquid ejection head is capable of recording a high-quality image with an increased density of liquid passages and nozzle orifices.
    • 液体喷射头包括多个孔,与孔连通的多个室,与室连通的多个流体阻力部分,多个液体通道,每个液体通道包括至少一个室和至少一个室 流体阻力部分,各自包括相邻的液体通道的多个通道组,以及多个第一分隔件和多个第二分隔件。 孔喷出液滴。 流体阻力部分各自比腔室窄。 设置有空隙的每个第一隔板分隔相邻的液体通道。 没有设置有空隙的每个第二分隔件分隔相邻的通道组。 液体喷射头能够记录具有增加的液体通道和喷嘴孔密度的高质量图像。
