Title:
INKJET HEAD AND INKJET RECORDING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/110035
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an inkjet head which prevents deformation of a spacer member arranged in a state not in contact with an actuator and which has a simplified assembly, and to provide an inkjet recording device. This inkjet head is provided with a pressure chamber substrate which is formed by arranging multiple pressure chambers two-dimensionally, multiple actuators 60 which are arranged corresponding to the pressure chambers and which apply pressure to the pressure chambers, multiple nozzles which allow the pressure chambers to communicate with the outside and which discharge liquid in the pressure chambers as droplets, and a spacer member 40 which is thicker than the actuators 60. The spacer member 40 has substrate areas 40a which, in a state not in contact with an actuator 60, are adhered to the pressure chamber substrate, and beam areas 40b which extend from one position to another position of a substrate 40a and are separated from the pressure chamber substrate and the actuators.
