| 发明名称 | Inkjet head having high mechanical strength and method of manufacturing the same | ||
| 摘要 | According to one embodiment, an inkjet head includes a nozzle plate including a first surface, a second surface opposite to the first surface, a through hole configured to make the first surface communicate with the second surface, and a cylindrical member integrally extending from the second surface by extending the through hole. An ink pressure chamber communicating with the cylindrical member and the through hole is provided on the second surface side of the nozzle plate. This inkjet head also includes an actuator which discharges ink in the ink pressure chamber from the through hole by displacing the nozzle plate. | ||

| 主权项 | 1. An inkjet head comprising: a nozzle plate including a first surface, a second surface opposite to the first surface, a through hole configured to make the first surface communicate with the second surface, and a cylindrical member continuously and integrally extending from the second surface by extending the through hole; an ink pressure chamber provided on the second surface side of the nozzle plate and communicating with the cylindrical member and the through hole; and an actuator configured to discharge ink in the ink pressure chamber from the through hole by displacing the nozzle plate, wherein the cylindrical member includes a tapered ink channel whose sectional area gradually decreases toward the through hole. | ||
