Title (EN) INKJET RECORDING DEVICE
(FR) DISPOSITIF D'IMPRESSION À JET D'ENCRE
(JA) インクジェット記録装置
Abstract:
(EN) Provided is an inkjet recording device that suppresses recording head (22) positioning aberrations caused by temperature differences between the recording heads (22) and an attachment member (201). The inkjet recording device comprises: recording heads (22) that have a first ink flow path part that communicates with a nozzle; a thermally conductive attachment member (201) that has the recording heads (22) attached thereto; an ink storage part that stores ink that is supplied to the recording heads (22); an ink-temperature adjustment means that adjusts the temperature of the ink stored in the ink storage part; an ink circulation path that passes through the ink storage part and through a second ink flow path part (304a), which communicates with the first ink flow path parts, and that circulates the ink that is stored in the ink storage part; and a liquid delivery means that performs a liquid delivery operation that makes the ink inside the ink circulation path flow in a prescribed liquid delivery direction and thereby makes the ink in the ink storage part circulate through the ink circulation path. At least one section of the second ink flow path part (304a) directly or indirectly contacts the attachment member (201).
(FR) L'invention concerne un dispositif d'impression à jet d'encre qui supprime les aberrations de positionnement de tête d'impression (22) provoquées par les différences de température entre les têtes d'impression (22) et un élément de fixation (201). Le dispositif d'impression à jet d'encre comprend : des têtes d'impression (22) qui ont une première partie trajet d'écoulement d'encre qui communique avec une buse ; un élément de fixation thermiquement conducteur (201) sur lequel les têtes d'impression (22) sont fixées ; une partie de stockage d'encre qui stocke l'encre qui est alimentée aux têtes d'impression (22) ; un moyen de réglage de température d'encre qui règle la température de l'encre stockée dans la partie de stockage d'encre ; un trajet de circulation d'encre qui passe à travers la partie de stockage d'encre et à travers une seconde partie trajet d'écoulement d'encre (304a), qui communique avec les premières parties trajet d'écoulement d'encre et qui fait circuler l'encre qui est stockée dans la partie de stockage d'encre ; et un moyen de distribution de liquide qui réalise une opération de distribution de liquide qui amène l'encre à l'intérieur du trajet de circulation d'encre à s'écouler dans une direction de distribution de liquide prescrite et amène ainsi l'encre dans la partie de stockage d'encre à circuler à travers le trajet de circulation d'encre. Au moins une section de la seconde partie trajet d'écoulement d'encre (304a) vient directement ou indirectement en contact avec l'élément de fixation (201).
(JA) 記録ヘッド(22)と取付部材(201)との温度差に起因する記録ヘッド(22)の位置ずれを抑制するインクジェット記録装置を提供する。インクジェット記録装置は、ノズルに連通する第1のインク流路部を有する記録ヘッド(22)と、記録ヘッド(22)が取り付けられた熱伝導性を有する取付部材(201)と、記録ヘッド(22)に供給されるインクを貯留するインク貯留部と、インク貯留部に貯留されるインクの温度を調整するインク温度調整手段と、インク貯留部と第1のインク流路部に連通する第2のインク流路部(304a)とを通りインク貯留部に貯留されたインクが循環するインク循環経路と、インク循環経路内のインクを所定の送液方向に流動させてインク貯留部のインクをインク循環経路において循環させる送液動作を行う送液手段と、を備え、第2のインク流路部(304a)の少なくとも一部は、直接又は間接的に取付部材(201)に接触している。
