摘要： A method of producing a nozzle plate for use in an ink jet head includes the steps of (a) stretching a predetermined number of resin lines, each having a cross section corresponding in shape to each nozzle hole to be formed in an ink jet head, in the same arrangement as that of nozzle holes to be formed in the ink jet head, (b) plating the peripheral surface of each of the resin lines with a metal, while maintaining the arrangement of the resin lines, (c) forming a nozzle substrate so as to include the resin lines therein with the metal used in the plating of the resin lines, (d) slicing the nozzle substrate, and (e) removing the resin lines from the sliced nozzle substrate, thereby forming the nozzle plate. In the above method, the resin lines can be removed from the nozzle substrate, and then the nozzle substrate can be sliced so as to form the nozzle plate.

摘要： A piezoelectric printhead or other droplet deposition apparatus has parallel liquid containing channels defined by a base and displaceable walls, and covered by a cover number. The channels each have at least one nozzle for ejecting droplets. Each nozzle may be disposed in the base, the cover then having two ink supply parts spaced lengthwise of each channel on opposite sides of the nozzle. Alternatively two longitudinally spaced nozzles may be provided in the base of each channel. The cover may have a conductive track corrected to wall-displacing electrodes, the points of connection being outside the channels.

摘要： An ink jet recording head has an ink passage unit (1) formed by superposing a nozzle plate (3) with a plurality of nozzles (2); an ink passage plate (8) having a first and a second surfaces (8a, 8b), provided with a plurality of pressure producing chambers (5) connected to the plurality of nozzles (2), and an ink reservoir (7) communicating with the pressure, producing chambers (5) by means of ink inlet ports (6); and a cover plate (11) closely joined to the first surface (8a) of the ink passage plate (8). The cover plate (11) are deformed elastically by piezoelectric vibrators (10) to apply pressure to the ink contained in the pressure producing chambers (5). The ink passage plate (8) is a metal sheet (21) having the first and second surfaces (8a, 8b) of the ink passage plate (8). A through hole (20) for the ink reservoir (7) is formed from the first surface to the second surface in the metal sheet (21). A plurality of recesses (27) for forming the pressure producing chambers (5) are formed in the first surface of the metal sheet by press working.
