Abstract

A piezoelectric element driving circuit drives a plurality of piezoelectric elements having common electrodes and independent electrodes which are driven independently. The piezoelectric element driving circuit includes a first switch circuit (25; 25-1 to 25-n) enabling each of a plurality of piezoelectric elements of a first piezoelectric element group (34) having the common electrodes coupled in common in response to a first enable signal, a second switch circuit (26) enabling each of a plurality of piezoelectric elements of a second piezoelectric element group (35) in response to a second enable signal, where the piezoelectric elements of the second piezoelectric element group are different from the piezoelectric elements of the first piezoelectric element group, and a driving circuit part (31, 32, 33-1 to 33-n) driving in common the independent electrodes of the corresponding piezoelectric elements of the first and second piezoelectric element groups based on recording data.
