PIEZOELECTRIC INK JET PRINTER HEAD AND METHOD FOR MANUFACTURING THE SAME FOR SIMPLIFYING PROCESS BY CONSTRUCTING NOZZLE AS ONE PLATE

摘要

PURPOSE: A piezoelectric ink jet printer head and a method for manufacturing the same are provided to simplify the structure of the ink jet head by integrally constructing an ink storage part and a chamber. CONSTITUTION: A piezoelectric ink jet printer head includes an actuator part, an ink distribution part, and an ink supplying part. The piezoelectric ink jet printer has plural stacked plates. The actuator part includes a piezoelectric plate(62), a protection layer(66), and an elastic plate(70). The piezoelectric plate(62) is inserted between an upper electrode(68) and a lower electrode(60). The protection layer(66) is positioned at an upper side of the upper electrode(68). The elastic plate(70) is arranged at a lower side of a lower electrode(60). The ink distribution part includes a spacer, a channel plate(56), and a nozzle plate(52). The spacer is arranged at a lower part of the elastic plate(70) and forms a side part of a chamber. The channel plate forms an ink passage while extending the chamber.
