摘要： According to one embodiment, a liquid discharge head includes a flexible printed circuit (FPC) connected to piezoelectric elements. The FPC has a first end in the first direction. A wiring layer of the FPC has a first region at the first end and a cover layer covering on a second region. The piezoelectric elements are spaced from each other in a second direction and each has a first electrode on a side surface facing towards the FPC. The first side has a joint surface facing the first region of the wiring layer. The first electrode is electrically connected to the wiring layer at the joint surface. The side surface includes a step portion that is recessed from the joint surface. A portion of the cover layer protrudes into a space adjacent to the step portion.

摘要： In accordance with one embodiment, an inkjet head comprises a plurality of groove-shaped pressure chambers formed on piezoelectric members of which the polarization directions are opposite, and a nozzle plate arranged at the lateral side of the pressure chambers across a lid section with high rigidity. A plurality of through holes connected to a plurality of nozzles formed on the nozzle plate is formed in the lid section. The inkjet head is set in a range of 10-25% before and after a center, that is, a length ratio where the relation between ejection voltage of ink ejected from the nozzles and a length ratio between the length of the through hole of the lid section in the longitudinal direction of the pressure chamber and the length of the pressure chamber in the longitudinal direction of the pressure chamber is minimized.

摘要： A liquid ejecting head of a side shooter type includes a plate including a plurality of nozzles arranged along a first direction and an actuator with a plurality of pressure chambers arranged along the first direction. Each pressure chamber communicates with a corresponding one of the nozzles. The actuator further includes dummy chambers, each of which is between two otherwise adjacent pressure chambers. Common chambers are provided in the actuator. The pressure and dummy chambers are arranged between the common chambers. The end portions of the pressure chambers are connected to a common chamber. The width of the end portions of each of the pressure chambers is less than the width of a portion of the pressure chamber between the end portions.
