Title (EN) FLOW CHANNEL MEMBER, LIQUID EJECTION HEAD, AND RECORDING MEDIUM
(FR) ÉLÉMENT DE CANAL D'ÉCOULEMENT, TÊTE D'ÉJECTION DE LIQUIDE ET SUPPORT D'ENREGISTREMENT
(JA) 流路部材、液体吐出ヘッドおよび記録装置
Abstract:
(EN) This flow channel member (4) has a common flow channel (5) and a separate flow channel (14) connected to the common flow channel (5). The separate flow channel (14) has a connection port (12a), an ejection port (8), and a pressurization chamber (10). The connection port (12a) opens into the common flow channel (5). The ejection port (8) opens to the outside. The common flow channel (5) has a support part (17). The support part (17) connects two portions on an inner wall surface of the common flow channel (5) so as to traverse the inside of the common flow channel (5). The support part (17) has a through-hole (17a) or a notch in a region overlapping with the connection port (12a) when viewed in a plan view.
(FR) L'invention concerne un élément de canal d'écoulement (4) qui a un canal d'écoulement commun (5) et un canal d'écoulement séparé (14) relié au canal d'écoulement commun (5). Le canal d'écoulement séparé (14) comporte un orifice de raccordement (12a), un orifice d'éjection (8) et une chambre de mise sous pression (10). L'orifice de raccordement (12a) s'ouvre dans le canal d'écoulement commun (5). L'orifice d'éjection (8) s'ouvre vers l'extérieur. Le canal d'écoulement commun (5) a une partie de support (17). La partie de support (17) relie deux parties sur une surface de paroi interne du canal d'écoulement commun (5) de façon à traverser l'intérieur du canal d'écoulement commun (5). La partie de support (17) a un trou traversant (17a) ou une encoche dans une région se chevauchant avec l'orifice de raccordement (12a) dans une vue en plan.
(JA) 流路部材(4)は、共通流路(5)と、共通流路(5)に繋がっている個別流路(14)と、を有している。個別流路(14)は、接続口(12a)と、吐出口(8)と、加圧室(10)と、を有している。接続口(12a)は共通流路(5)内へ開口している。吐出口(8)は外部へ開口している。共通流路(5)は支持部(17)を有している。支持部(17)は、共通流路(5)の内部を横断するように共通流路(5)の内壁面における2つの部分を繋いでいる。支持部(17)は、平面視において接続口(12a)と重なる部分に貫通孔(17a)または切り欠きを有している。
