Abstract:
An ink-jet recording device to selectively eject ink to form an image on a recording medium, said recording device comprising:(a) a first wall member arranged adjacent to an ink material to be ejected;(b) a second wall member arranged adjacent to an ink material to be ejected, said second wall member has an elasticity different from that of said first wall member;(c) a first piezoelectric member arranged adjacent to said first wall member, said first wall member separating the first piezoelectric member from said ink material that is adjacent to said first wall member, said first piezoelectric member being deformable and adapted to deform said first wall member to eject an ink droplet of said ink material adjacent to said first wall member; and(d) a second piezoelectric member arranged adjacent said second wall member, said second wall member separating the second piezoelectric member from said ink material that is adjacent to said second wall member, said second piezoelectric member being deformable and adapted to deform said second wall member to eject an ink droplet of said ink material adjacent to said second wall member.
