    摘要： An ink jet type recording head composed of a plurality of head units and having a large number of nozzles without greatly increasing the width of the recording head. Outer walls 1a, 1b of a spacer 1 of the heat unit are inclined at an angle .theta. with respect to the arrangement lines A--A, B--B of pressure generating chambers 2, 3. A plurality of head units (e.g., 40, 41) are arranged so that end surfaces of the head units in the arrangement direction of the pressure generating chambers 2, 3 are adjacent to each other. The head units are fixed to a base board 28 such that they are shifted in a direction roughly perpendicular to the arrangement direction of then pressure generating chambers 2, 3 and so that an interval between the pressure generating chambers 2, 3 of the adjacent head units is the same as the pitch between the pressure generating chambers 2, 3 on each individual head unit. Accordingly, it is possible to arrange the nozzle openings of the plurality of head units at a uniform pitch even over several head units and nonetheless maintain the width of the entire recording head as narrow as possible.

    摘要： An actuator for an ink jet printer includes: an ink tank comprising a thick substrate having a cavity structure and a vibrating plate covering a cavity; and a piezoelectric/electrostrictive working portion comprising an upper electrode layer, a lower electrode layer, and a piezoelectric/electrostrictive layer between the electrode layers, the piezoelectric/electrostrictive working portion being disposed on the ink tank so that the lower electrode layer contacts with the vibrating plate. The upper electrode is trimmed only in the portion where the piezoelectric/electro-strictive layer covers the vibrating plate so as to control an effective electrode area and adjust an ink jet volume to be appropriate. The upper electrode layer is trimmed with the piezoelectric/electrostrictive layer covering the vibrating plate at least near the portion to be trimmed of the upper electrode layer so as to control an effective electrode area and adjust an ink jet volume.
