Abstract

PURPOSE:To improve a multinozzle head in resolving power by opening a valve provided at an exhaust port communicated with one end of a pressure equalizing pipe provided for an ink chamber to exhaust air and bubbles in the ink chamber, then jetting ink and thus making the size of ink drops uniform. CONSTITUTION:If a recording switch is closed, a pump operates and an electromagnetic valve 14 opens to pressurize and supply ink from an ink tank to a pipe 10 via a supply port 5. A part of the ink flows into an ink chamber 4 through holes 11 and the rest of it passes through the pipe 10 while sucking air and bubbles staying in the ink chamber 4 from holes 11 on an exhaust port 12 side and is exhausted from the exhaust port 12. If air, etc., are removed from the ink chamber 4, the electromagnetic valve 14 is closed, and at the same time, an electrostriction vibrator 8 operates and a vibrating plate 3 is vibrated. Ink whose pressure distribution is made uniform near a nozzle 2 is jetted from the nozzle 2 in ink drops.
