Abstract

PURPOSE: To simplify the structure and lower the cost by a method wherein in a device in which a volume of an ink flow path is changed by a piezoelectric transducer for jetting ink, the ink flow paths are radially disposed on the flat surface of the piezoelectric transducer.
CONSTITUTION: A piezoelectric transducer 1 formed by laminating two disk-form piezoelectric ceramics plates 2, 3 is provided rotatably about a rotation center. Ink flow paths 6 to be filled with ink and side walls 60 are disposed radially about a rotating shaft 30 of the piezoelectric transducer 1. On the periphery of the transducer 1, an orifice plate ring 12 having orifices 10 connecting to the ink flow paths 6 is provided. Under the upper piezoelectric ceramics plate 2, an LSI chip 16 covered with an insulating layer 32 is loaded. The ink flow path 6 has a rectangular cross section which is reduced in width toward the rotation center 7. On the surface of each of the side walls 60 inside the flow path, an electrode 4 treated to be insulated from ink is provided.
