Abstract:
1. A liquid droplet jetting apparatus which jets a droplet of a liquid onto a medium, comprising: a liquid droplet jetting head which jets the droplet, including: a voltage applying mechanism which applies a voltage to the piezoelectric actuator, wherein when a voltage is applied to the first active portions and the second active portions by the voltage applying mechanism, the first active portions and the second active portions both elongate in a first direction toward the pressure chambers, and contract in a second direction which is orthogonal to the first direction, respectively, and when the voltage applying mechanism applies the voltage to the first active portions, the voltage applying mechanism does not apply the voltage to the second active portions, and when the voltage applying mechanism does not apply the voltage to the first active portions, the voltage applying mechanism applies the voltage to the second active portions.
