    • A liquid droplet flight device is provided that moves an ink or the like using a comparatively low voltage and stably causes flight of even a high viscosity ink or the like. When causing droplets of a liquid inside a liquid retaining section to fly onto a medium transported between liquid droplet discharge means and an opposing electrode in the liquid droplet flight device, a high voltage is applied to the flight electrode from a bias power source to generate an electric field between the flight electrode and the opposing electrode. On/off control of flight control means is performed in this state to apply a drive voltage of a low voltage to an EW drive electrode from a drive power source such that the liquid inside a slit moves to a leading end portion of the flight electrode due to an electrowetting phenomenon, and the liquid that has moved to the leading end portion of the flight electrode flies toward the opposing electrode through the electric field such that a liquid droplet lands on the medium.
    • 提供了使用较低电压移动墨水等的液滴飞行装置,并且稳定地引起甚至高粘度墨水等的飞行。 当使液体保持部分内的液滴液滴飞溅到在液滴排出装置中的液滴排出装置和相对电极之间运送的介质上时,高压从偏压电源施加到飞行电极,以产生 飞行电极与对置电极之间的电场。 在该状态下执行飞行控制装置的开/关控制,以从驱动动力源向EW驱动电极施加低电压的驱动电压,使得狭缝内的液体移动到飞行电极的前端部,由此 并且已经移动到飞行电极的前端部的液体通过电场朝向相对电极飞行,使得液滴落在介质上。
