Abstract

A liquid discharging apparatus has: a discharging section that discharges a liquid when at least one of a first piezoelectric element and a second piezoelectric element is driven; In a first mode in which the driving signal is output from the second output portion, the switch control circuit controls the first switch so as not to create a continuity and controls the second switch so as to create a continuity. In a second mode in which the constant-voltage signal is output from the second output portion, the switch control circuit controls the first switch so as to create a continuity and controls the second switch so as not to create a continuity.
