Title (EN) INK JET HEAD AND INK JET RECORDING APPARATUS
(FR) TÊTE À JET D'ENCRE ET APPAREIL D'ENREGISTREMENT À JET D'ENCRE
(JA) インクジェットヘッド及びインクジェット記録装置
Abstract:
(EN) The present invention addresses the problem of providing an ink jet head and an ink jet recording apparatus capable of satisfactorily removing remaining air bubbles inside a pressure chamber. To solve the above problem, the present invention is provided with: a common ink chamber 41 that stores ink; at least one pressure chamber 23 that communicates with the common ink chamber 41 and causes a volume fluctuation by means of pressure generation means; a nozzle 22 that communicates with the pressure chamber 23; a nozzle-part discharge path 26a that communicates with the pressure chamber 23 near the nozzle 22 inside the pressure chamber 23 and discharges the ink inside the pressure chamber 23; and at least one discharge path that communicates with the pressure chamber 23 at a position distant from the nozzle 22 inside the pressure chamber 23 and causes the ink inside the pressure chamber 23 to be discharged.
(FR) La présente invention porte sur le problème de la fourniture d'une tête à jet d'encre et d'un appareil d'enregistrement à jet d'encre aptes à éliminer de manière satisfaisante les bulles d'air restantes à l'intérieur d'une chambre de pression. Afin de résoudre le problème ci-dessus, la présente invention comprend : une chambre d'encre commune (41) qui stocke de l'encre ; au moins une chambre de pression (23) qui communique avec la chambre d'encre commune (41) et amène une fluctuation de volume au moyen d'un moyen de génération de pression ; une buse (22) qui communique avec la chambre de pression (23) ; un trajet d'évacuation de partie buse (26a) qui communique avec la chambre de pression (23) à proximité de la buse (22) à l'intérieur de la chambre de pression (23) et évacue l'encre à l'intérieur de la chambre de pression (23) ; et au moins un trajet d’évacuation qui communique avec la chambre de pression (23) en une position éloignée de la buse (22) à l'intérieur de la chambre de pression (23) et amène l'encre à l'intérieur de la chambre de pression (23) à s’évacuer.
(JA) 本発明は、圧力室内の残留気泡を良好に排除できるようになされたインクジェットヘッド及びインクジェット記録装置の提供することを課題とし、上記課題は、インクを貯留する共通インク室41と、共通インク室41に連通し圧力発生手段によって容積変動を生ずる少なくとも1つの圧力室23と、圧力室23に連通したノズル22と、圧力室23内のノズル22の近傍において圧力室23に連通し、圧力室23内のインクを排出させるノズル部排出路26aと、圧力室23内のノズル22から離れた位置において圧力室23に連通し、圧力室23内のインクを排出させる少なくとも1つの排出路とを備えることにより解決される。
