LIQUID EJECTION DEVICE AND EJECTION METHOD

摘要

A liquid ejection device, includes: a plurality of storing parts for storing liquids; a plurality of liquid-feeding parts connected to the respective storing parts; a ejection part for ejecting a liquid; a plurality of flow paths connected to the plurality of liquid-feeding parts, respectively; and a connection part for joining the plurality of flow paths and connecting them as a single flow path to the ejection part. The plurality of liquid-feeding parts are actuated to mix the liquids from the plurality of storing parts in the single flow path joined at the connection part and feed a mixture of the liquids to the ejection part to eject the mixture from the ejection part. According to the ejection device of the present invention, the ejection amount or the mixing ratio can be easily changed in a comparatively precise manner.
