摘要： An ink jet recording head having high printing quality which is achieved independently of ambient temperature changes. An overhang portion (22) is formed on a surface of a frame (20) in such a manner that the overhang portion extends close to an island portion (9) of a resilient plate. A front end (17) of a fixed board (14) is fixed to the overhang portion (22) so that a gap (23) is interposed between a lateral side of the fixed board (14) and the frame (20). The piezoelectric vibration elements (8) are secured to the opposite end of the fixed board and abut against each of the island portions. The thickness (L0) of the overhang portion (22) affects that thermal expansion differential derived from a difference in the materials of the frame (20) and the piezoelectric vibration element. Since the thickness is minimized, the thermal expansion differential between the frame (20) and the piezoelectric vibration elements (8) is correspondingly minimized.

摘要： An ink jet recording head formed by laminating and fixing: a flow path forming plate having through holes for defining pressure producing chambers, ink supply inlets, and a common ink chamber, a nozzle plate having nozzle openings communicating with the pressure producing chambers, and a vibration plate having diaphragm portions that are resiliently deformed in response to displacement of piezoelectric vibration elements one upon another with an adhesive so as to be watertight. The vibration plate has frame-like thick wall portions that extend as far as to the ink supply inlet side of the pressure producing chamber as well as to the inner side of the nozzle opening, and portions closer to a piezoelectric vibration element than to both ends of the pressure producing chamber are made to be supported by a base. As a result of this construction, a nonsupported region of the pressure producing chamber can be shortened, which in turn improves the rigidity of a substrate unit as a whole.

摘要： A pressurizing chamber 1 is formed as a recess by half etching of a silicon single-crystal substrate 2. A nozzle communicating hole 6 through which the pressurizing chamber 1 is connected to a nozzle opening 5 is formed as a through hole which is smaller in width than the pressurizing chamber 1. The pressurizing chamber 1 is connected to the nozzle opening 5 in the other face via the nozzle communicating hole 6 while reducing the volume of the pressurizing chamber 1 to a degree as small as possible. The silicon single-crystal substrate is used as a member constituting a spacer so that an ink drop of a reduced ink amount suitable for high density printing flies with high positioning accuracy.
