Title: Ink jet recording head
Inventor: OKUBO KATSUHIRO
IPC: B41J2/045
Filed: 2000-04-10
Abstract: PROBLEM TO BE SOLVED: To provide an ink jet recording head in which ejection characteristics can be prevented from deteriorating by enhancing the performance for discharging a bubble intruded into an ink storage chamber. SOLUTION: The ink jet recording head comprises a pressure generating chamber 2 communicating with a nozzle 3, a piezoelectric oscillator 6 for ejecting an ink drop from a nozzle opening 3 by generating a pressure in the pressure generating chamber 2, and a chamber 4 for storing ink being supplied to the pressure generating chamber 2. Since a circumferential groove 26 for increasing the depth dimension of the ink storage chamber 4 is made in the ceiling part at the circumferential fringe region in the vicinity of wall face of the ink storage chamber 4, pressure loss is reduced at the circumferential fringe region in the vicinity of wall face where bubbles stand easily and the dynamic pressure and current velocity of ink are enhanced in that region at the time of suction.  Consequently, the performance for discharging a bubble intruded into the ink storage chamber 4 is enhanced remarkably and ejection characteristics are prevented from deteriorating.
