Title (EN) LIQUID EJECTION DEVICE AND EJECTION METHOD
(FR) DISPOSITIF D'EJECTION DE LIQUIDE ET PROCEDE D'EJECTION
Abstract:
(EN) 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.
(FR) Dispositif d'éjection de liquide comprenant : une pluralité de composants de stockage destinés à stocker des liquides ; une pluralité de composants d'alimentation en liquides reliés aux composants de stockage respectifs ; un composant d'éjection destiné à éjecter un liquide ; une pluralité de passages d'écoulement reliés à la pluralité de composants d'alimentation en liquides, respectivement ; et un composant de connexion destiné à raccorder la pluralité de passages d'écoulement et à les relier en tant que passage d'écoulement unique au composant d'éjection. La pluralité de composants d'alimentation en liquides est actionnée pour mélanger les liquides provenant de la pluralité de composants de stockage dans le passage d'écoulement unique raccordé au niveau du composant de connexion et amener un mélange des liquides au composant d'éjection pour éjecter le mélange à partir du composant d'éjection. Selon le dispositif d'éjection de la présente invention, la quantité éjectée ou les proportions du mélange peuvent être modifiés facilement d'une manière relativement précise.
