Abstract

PURPOSE:To provide the heat of simple constitution, small size and high performances by encircling pressure generating layers with an ink filling path provided with a deaerating hole in the upper part and adjusting the clearance of a capillary layer communicating the pressure generating layer and filling path. CONSTITUTION:When ink is supplied to an annular ink filling path 20 through supply pipe 2 by opening a deaerating hole 21, the ink is well filled without performing vacuum suction or other. The pressure generating layers 16 connecting to the orifices 18 ..., pressure propagating paths 17 ... of head body 15 are encircled by the filling path 20 and are opposed to a diaphragm 26. The holding frame 25 of this diaphragm 26 and the body 15 are integrated through a packing 29 and when the thickness of the packing 29 is selected, the clearance of the capillary layer 31 communicating between the layers 16 ... and filling path 20 is adjusted and the ink drops fly out from the nozzles 18 ... with good responsiveness. Thereby, the need for integrating single heads is eliminated.
