ABSTRACT:
A multi-ink-jet head in which a plurality of ink distribution tubes each having a nozzle at one end thereof are extended in parallel with each other at a predetermined pitch and n piezoelectric element arrays are mounted on the tube array in such a way that each piezoelectric element array comprising a plurality of piezoelectric elements each of which is mounted on each tube group comprising n (where n is an integer greater than one) ink distribution tubes and the piezoelectric elements in one array are staggered by one ink distribution tube or one pitch from those in the preceding piezoelectric element array so that each ink distribution tube is mounted with n piezoelectric elements each belonging to each piezoelectric element array. Only when n piezoelectric elements on one ink distribution tube are excited simultaneously, a stream of ink can be emitted through the nozzle of said one ink distribution tube.
