摘要： After assembling an ink jet recording head which includes a plurality of nozzle orifices forming at least one nozzle row, pressure chambers each communicated with the associated nozzle orifice, pressure generating elements each generating pressure fluctuation in ink provided in the associated pressure chamber to eject an ink droplet from the associated nozzle orifice, a natural period of the ink pressure fluctuation in the pressure chamber of the assembled recording head is measured. Then the assembled recording head is classified into a plurality of ranks, based on the measured natural period.

摘要： A method of driving an ink jet recording head comprising the steps of: retreating a vibrating plate to a predetermined position from a nozzle opening at such a speed as to allow a meniscus at the nozzle opening to be jetted from the nozzle opening while applying a drive voltage to a piezoelectric vibrating element; holding the vibrating plate at the position; and advancing the vibrating plate toward the nozzle opening when the meniscus has returned to a position 1/3 or more of the farthest retreat position thereof. As a result, a pressure chamber contracted to thereby apply pressure to ink when inertial stream of the ink become stable and heads toward the nozzle opening, producing an ink droplet to be jetted at a predetermined speed irrespective of the position of the meniscus.

摘要： In a vibrator unit, at least one piezoelectric vibrator is fixed on a base member in a cantilevered manner, such that a first region of the piezoelectric vibrator is fixed on a first face of the base member. A resin case is formed with a housing space extending through a first end face to a second end face thereof. The housing space includes a first housing part which opens to the first end face of the case, a second housing part which continues to the first housing part, and a third housing part which continues to the second housing part. In the first housing part, a part of the piezoelectric vibrator except for the first region is housed. The second housing part is defined by a first inner face extending in a first direction which is parallel with an extending direction of the piezoelectric vibrator, on which a first part of a second face of the base member which is opposite to the first face is bonded, and a second inner face extending in a second direction which is perpendicular to the first direction, on which a part of a third face which connects the first face and the first part of the second face is bonded. The third housing part is isolated from a part of the base member which includes a second part of the second face.
