    • PROBLEM TO BE SOLVED: To provide an inkjet printing head of a piezoelectric system with one-way shutters. SOLUTION: The inkjet printing head is equipped with a plurality of pressure chambers to be filled with ink to be ejected, a piezoelectric actuator which provides a driving force for ejection of the ink to each of the plurality of pressure chambers, a manifold which includes the ink supplied to each of the plurality of pressure chambers, a plurality of restrictors for feeding the ink to the plurality of pressure chambers from the manifold, a plurality of nozzles for ejecting the ink from the plurality of pressure chambers, and a plurality of the one-way shutters set at respective outlets of the plurality of restrictors. The one-way shutter opens the restrictor when the ink is supplied from the restrictor to the pressure chamber, and blocks a backflow of the ink by shutting the restrictor when the ink is ejected from the pressure chamber through the nozzle.

    • PROBLEM TO BE SOLVED: To provide an inkjet printing head equipped with cantilever actuators.
      SOLUTION: The inkjet printing head is equipped with a plurality of ink chambers to be filled with ink to be ejected, a manifold which stores the ink to be supplied to the plurality of ink chambers, a plurality of restrictors for feeding the ink from the manifold to each of the plurality of ink chambers, a plurality of nozzles for ejecting the ink from the plurality of ink chambers, and the cantilever actuators set so as to each keep one end fixed to the inside of each ink chamber and the other end deformed by deflection. The cantilever actuator applies a pressure for ejection of the ink to the ink inside of the ink chamber by the deflection deformation of its other end. The cantilever actuator consists of a bimorph element, and blocks a backflow of the ink towards the restrictor side from the ink chamber at the same time as when the ink is ejected from the ink chamber through the nozzle by the deflection deformation of the other end.
