The technology of an inkjet printer is expected to be used in digital printing and in printing to various kinds of materials. Consequently, fast and stable ink-ejection technology is required to meet the diversified needs. The conventional droplet discharge was performed by applying a momentarily higher pressure using a piezoelectric element.In this study, we focused on the generation process of pressure in the pressure chamber and the possibility of generating an ink droplet by experimentally making a liquid droplet ejection device using multiple actuatorsKey Words :Multiple actuators,Inkjet,Piezoelectric elements
