Inkjet head and inkjet recording apparatus with integrated nozzles and actuators
Abstract:
According to one embodiment, an inkjet head includes a substrate, a nozzle plate, and an actuator incorporated in the nozzle plate. The nozzle plate includes a nozzle provided to communicate with an ink pressure chamber, and a vibrating plate exposed to the ink pressure chamber. The actuator displaces the vibrating plate in the thickness direction to pressurize ink in the ink pressure chamber via the vibrating plate and eject the ink from the nozzle. The ink pressure chamber has a first dimension in the thickness direction of the substrate and a second dimension in a direction orthogonal to the thickness direction of the substrate. The first dimension is larger than the second dimension.
