    • An ink-jet head having a passage unit including pressure chambers each having one end coupled to a nozzle and the other end to be coupled to an ink supply source. The pressure chambers are arranged along a plane to neighbor each other. The ink-jet head further includes actuator units attached to a surface of the passage unit for changing the volume of each pressure chamber. Each actuator unit includes pressure generation portions respectively corresponding to pressure chambers, and is formed to extend over the pressure chambers. The actuator units are arranged along the longitudinal direction of the passage unit so that each neighboring actuator units partially overlap each other in the lateral direction of the passage unit. Each actuator unit has a basic region where many pressure generation portions are formed in a matrix, and an additional region neighboring the basic region in the lateral direction of the passage unit. In the additional region, pressure generation portions are formed to correspond to a gap portion between the pressure generation portions in the basic region of the actuator unit and the pressure generation portions in the basic region of another actuator unit neighboring that actuator unit.
    • 一种具有通道单元的喷墨头,该通道单元包括压力室,每个压力室的一端连接到喷嘴,另一端连接到墨水供应源。 压力室沿着平面布置以彼此相邻。 喷墨头还包括附接到通道单元的表面的致动器单元,用于改变每个压力室的体积。 每个致动器单元包括分别对应于压力室的压力产生部分,并且形成为在压力室上延伸。 致动器单元沿着通道单元的纵向布置,使得每个相邻的致动器单元在通道单元的横向上部分地彼此重叠。 每个致动器单元具有基本区域,其中许多压力产生部分以矩阵形成,以及与通道单元的横向方向上的基本区域相邻的附加区域。 在附加区域中,压力产生部分形成为对应于致动器单元的基本区域中的压力产生部分之间的间隙部分和与该致动器单元相邻的另一致动器单元的基本区域中的压力产生部分。
