摘要： A head driving apparatus including a plurality of piezoelectric elements, a switch circuit, a head driving circuit, a controller, and a determination unit. The controller supplies a control signal to the switch circuit so as to ON-OFF control the switch units every jet timing based upon jetting data. The determination unit calculates a total number of the switch units to be turned ON simultaneously in accordance with the control signal, and supplies a restriction signal to the switch circuit when the total number exceeds a predetermined number. A part of the switch units are turned OFF in spite of the control signal supplied from the controller when the switch circuit receives the restriction signal from the determination unit.
