Abstract

PURPOSE:To prevent nozzles from being clogged with chips generated in lapping, by a method wherein a plate provided with nozzles is shaped to a predetermined nozzle length, other plates are adhered to the plate in the condition of protruding beyond a front surface of the nozzles, and the protruding plates are lapped so that the lapped surfaces are flush with the front surface of the nozzles while ejecting a fluid through the nozzles. CONSTITUTION:A sheet 1 in which the nozzle size measured from the part where the nozzles 3A, 3B,... are exposed to ink leading-out passages 4A, 4B,... is adjusted to a predetermined size is prepared. A sheet 12 to be provided with an ink-supplying pipe and piezoelectric elements in the subsequent step is laid on the sheet 11 so that it protrudes beyond the front surface of the nozzles 3A, 3B. A flat plate form sheet 13 to be a bottom plate is provided on the lower side of the sheet 11 so as to protrude beyond the front surface of the nozzles. The sheets are adhered to each other by welding. Thereafter, the sheets 12, 13 are lapped in the directions of arrows B, C, while introducing a fluid through the nozzles 3A, 3B,... so as to prevent the chips 15 from entering into the nozzles. The sheets 12, 13 are lapped to the front surface A of the nozzles 3A, 3B,... of the sheet 11 so that the nozzle surfaces of all the sheets are flush with each other.

tb+ Technology Background A voltage is applied to a piezoelectric element installed on a pressure chamber containing print recording ink to cause distortion based on the print information, and the stress caused by this distortion is transmitted to the pressure chamber to increase the pressure. An inkjet recording method is well known in which printing ink contained in a pressure chamber is ejected onto recording paper from a nozzle that communicates with the pressure chamber and is provided at one end of the pressure chamber. This inkjet recording method is a non-impact recording method, generates little noise during print recording, and has good recording quality, so it has recently become widely used for recording information output from electronic computers.
