摘要： An ink jet printer head includes a cavity plate and an actuator with the following configuration. The cavity plate is formed with four columns of pressure chambers. Each pressure chamber has a parallelogram shape with two acute-angle portions formed with an ink supply opening and an ink ejection nozzle opening, respectively. The pressure chambers in the center two columns are arranged with the ejection-nozzle sides interposed between each other. The pressure chambers in the outer two columns are arranged with the ejection-nozzle sides interposed between ink-supply sides of the center two columns. The pressure chambers are arranged so that, although the pressure chambers are partially interposed between each other, the principal portion of each pressure chamber in one column is shifted out of alignment from principal portions of pressure chambers in adjacent columns with respect to the direction in which the long side of the pressure chambers extend. The actuator unit is disposed across the plurality of pressure chambers and includes a plurality of pressure generating portions at positions that correspond to the pressure chambers.

摘要： 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.
