Claim Text:
1. A capacitive load drive circuit comprising: a first capacitive load group including a plurality of first capacitive loads that are supplied a first driving signal; a second capacitive load group including a plurality of second capacitive loads that are supplied a second driving signal; a first driving signal generator that generates the first driving signal from a first control signal according to characteristics of the first capacitive load group; a second driving signal generator that generates the second driving signal from a second control signal according to characteristics of the second capacitive load group; and a control signal supply portion that supplies a common control signal to the first driving signal generator and the second driving signal generator; wherein the first driving signal generator corrects the common control signal to generate the first control signal, and the second driving signal generator corrects the common control signal to generate the second control signal.
