Title
(EN) INKJET PRINTING APPARATUS AND INK TANK
(FR) APPAREIL D'IMPRESSION À JET D'ENCRE ET RÉSERVOIR D'ENCRE
Abstract
(EN)
An inkjet printing apparatus includes an ink tank that contains an ink to be supplied to a printing head that ejects the ink, the ink being injected from an ink bottle. The inkjet printing apparatus further includes an injection assistance member including a first passage and a second passage. The first passage is defined by a first upper end portion opening toward the outside of the ink tank and a first lower end portion opening toward the inside of the ink tank. The second passage is defined by a second upper end portion opening toward the outside of the ink tank and projecting upward less than the first upper end portion and a second lower end portion opening toward the inside of the ink tank and larger than the first lower end portion in terms of a distance from the bottom surface of the ink tank.

La présente invention concerne un appareil d'impression à jet d'encre comprenant un réservoir d'encre qui contient une encre destinée à alimenter une tête d'impression qui éjecte l'encre, l'encre étant injectée à partir d'une bouteille d'encre. L'appareil d'impression à jet d'encre comprend en outre un élément d'assistance à l'injection comprenant un premier passage et un second passage. Le premier passage est défini par une première partie d'une extrémité supérieure s'ouvrant vers l'extérieur du réservoir d'encre et une première partie d'une extrémité inférieure s'ouvrant vers l'intérieur du réservoir d'encre. Le second passage est défini par une seconde partie de l'extrémité supérieure s'ouvrant vers l'extérieur du réservoir d'encre et faisant saillie vers le haut moins loin que la première partie de l'extrémité supérieure et une seconde partie de l'extrémité inférieure s'ouvrant vers l'intérieur du réservoir d'encre et plus grande que la première partie de l'extrémité inférieure en termes d'une distance à partir de la surface inférieure du réservoir d'encre.
