  • INK JET HEAD AND INK JET DEVICE
    Publication number: 20170225480
    Abstract: An ink jet head includes a pressure chamber, a main flow path, an actuator, a nozzle, a first communication flow path, and a filter. The pressure chamber is filled with an ink. The main flow path supplies the ink to the pressure chamber. The actuator changes the pressure of the ink filled in the pressure chamber. The nozzle is connected to the pressure chamber and ejects the ink filled in the pressure chamber by driving of the actuator. The first communication flow path connects the pressure chamber to the main flow path. The filter is disposed at a predetermined position between the nozzle and the vicinity of a first boundary of the main flow path and the first communication flow path, and the filter captures an impurity in the ink which has a size larger than the diameter of the nozzle.
