Zusammenfassung:	PURPOSE:To eliminate clogging by providing a sound collecting body so as to sink under the ink of an ink sump. CONSTITUTION:The piezoelectric element 5 provided to the bottom part of each sound collecting body 2 is driven by applying a pulse signal to a driver circuit 4. The strain generated by the electrostriction phenomenon of the piezoelectric element 5 travels through the sound collecting body 2 in the form of a traveling wave of condensation and rarefaction while the amplitude thereof is amplified. The advance wave of large amplitude collected by the sound collecting body 2 is struck by ink 1 and, when the vertical wave thereof reaches the surface of the ink, the surface of the ink is pushed up and an ink particle 1a is discharged to the air. By this method, a print head enhanced in drying resistance and prevented from clogging is obtained.
