Abstract
The present invention provides a liquid droplet ejecting apparatus that may cool, with a simple configuration, drive sections of piezoelectric elements. Namely, the liquid droplet ejecting apparatus has head modules that use piezoelectric elements to eject ink droplets, driver ICs that drive the piezoelectric elements, a ventilation unit that delivers dry air to the environs of the piezoelectric elements via a gas delivery passage disposed therein in order to dehumidify the environs of the piezoelectric elements, a branch tube that branches from the gas delivery passage and blows onto the driver ICs some of the air that has been delivered, and a duckbill valve that is disposed in the branch tube. Here, the ventilation unit that delivers the dry air in order to dehumidify the environs of the piezoelectric elements also cools the driver ICs, so the driver ICs can be cooled with a simple configuration.
