IPC: B41J2/045
Filed: 2002-01-24
Abstract: <P>PROBLEM TO BE SOLVED: To obtain an ink jet head in which lowering of driving voltage and/or high density arrangement of pressure chambers are achieved while ensuring a minimum necessary ink ejection.  <P>SOLUTION: A pressure chamber 16 is surrounded by a wall body 36 including the opposite side walls 36a and 36b and the top wall 36c. When active parts formed in piezoelectric sheets 21b-21e elongate downward, the top wall 36c elongates downward and the opposite side walls 36a and 36b buckle and bend in the inward direction of the pressure chamber. Since the opposite side walls 36a and 36b, as well as the active part, contribute to volumetric variation of the pressure chamber, volume reduction rate of the pressure chamber 16 is enhanced when a voltage is applied to individual electrodes 24.  <P>COPYRIGHT: (C)2003,JPO
