Abstract
(EN)
Provided are a recording head and an ink jet recording apparatus provided with the same capable of cleaning an ink ejection surface while preventing damage to a wiper. The recording head (17) is provided with an ink ejection surface (F1) including an ink ejection region (R1) in which a plurality of ink ejection ports (18a) for ejecting ink (22) onto a sheet (S) is opened. With respect to the ink ejection region (R1), on the upstream side in a wiping direction in which a wiper (35) wipes the ink ejection surface (F1), a plurality of concave parts (64) is provided. Inside each of the concave parts (64), two or more cleaning liquid supply ports (60a) for supplying a cleaning liquid (23) are provided in the wiping direction.

Cette invention concerne une tête d'impression et un appareil d'enregistrement à jet d'encre doté de celle-ci, apte à nettoyer une surface de projection d'encre tout en évitant l'endommagement d'une racle. La tête d'impression (17) est pourvue d'une surface de projection d'encre (F1) comprenant une région de projection d'encre (R1) dans laquelle est ménagée une pluralité d'orifices de projection d'encre (18a) pour projeter de l'encre (22) sur une feuille (S). Par rapport à la région de projection d'encre (R1), sur le côté amont dans une direction d'essuyage dans laquelle une racle (35) essuie la surface de projection d'encre (F1), une pluralité de parties concaves (64) est formée. A l'intérieur de chacune des parties concaves (64), au moins deux orifices d'alimentation en liquide de nettoyage (60a) pour fournir un liquide de nettoyage (23) sont ménagés dans la direction d'essuyage.
