Abstract:
An ink jet recording head, comprising:a passage unit including at least one nozzle aperture, a chamber associating with said nozzle aperture, and an elastic plate serving as part of a wall of said chamber;a vibrator unit including a fixing plate, and a plurality of piezoelectric vibrators fixed at one end portion thereof to said fixing plate at a predetermined pitch and contacting said elastic plate at another end portion thereof, said piezoelectric vibrators being actuated in a longitudinal vibration mode for emitting an ink droplet by deflecting said elastic plate to expand or contract said pressure generating chamber; andan elastically deformable connecting member extending across said piezoelectric vibrators in a transverse direction and secured thereto, wherein said connecting member is fixed to a vibration area of said piezoelectric vibrators and controls the displacement of said piezoelectric vibrators.
