Verfahren zur Herstellung einer Tintenstrahlaufzeichnungsvorrichtung

摘要

A multinozzle ink jet recording device having a dense arrangement and a method of producing the same are disclosed. Two electrodes (8) for applying a voltage to the side walls (2) of a piezoelectric plate lie in the range of a pressure chamber (1), so that an electric field is prevented from acting on portions which do not contribute to the ejection of an ink drop. This obviates the waste of voltage and thereby realizes low voltage drive which reduces the size of the pressure chamber. All the grooves serve as pressure chambers without any slit or similar wasteful space intervening between them. This implements a multinozzle print head having a dense configuration. With such a print head, the recording device achieves a miniature and compact arrangement.
