Patent ID: 10350889

Abstract:
There are provided a liquid jet head and a liquid jet recording device each capable of appropriately cutting off the liquid column formed immediately after being jetted from the jet hole to prevent the satellite droplet from generating, and further achieving easier maintenance of the jet hole part. The liquid jet head includes a drive actuator, a jet hole plate, and a flow channel operating actuator. The drive actuator applies a pressure variation to a liquid filled therein. The jet hole plate is disposed on a downstream side of the drive actuator and adapted to jet the liquid having flown out from the drive actuator from the jet hole to the outside of the drive actuator. The flow channel operating actuator is disposed between the drive actuator and the jet hole plate, provided with a communication section adapted to communicate the drive actuator and the jet hole with each other, and has a configuration capable of performing a displacing operation on at least a part of the peripheral edge part of the communication section.
