Abstract

Official abstract text for this publication.

A liquid discharge apparatus includes first and second discharge sections, first and second connection paths and a voltage generation section. Each of the first and second discharge sections has a nozzle configured and arranged to discharge a liquid, a pressure chamber in communication with the nozzle, and a piezoelectric element. The first connection path selection section is arranged so as to correspond to the first discharge section and configured to selectively supply a plurality of voltages to the first discharge section. The second connection path selection section is arranged so as to correspond to the second discharge section and configured to selectively supply a plurality of voltages to the second discharge section. The voltage generation section is configured to generate and supply the voltages shared by the first connection path selection section and the second connection path selection section.
