摘要： PROBLEM TO BE SOLVED: To rapidly discharge air bubbles existing in a fluid supply passage through which fluid is supplied to a droplet ejection head from a nozzle of the droplet ejection head, so that an amount of fluid discharged from the nozzle with the discharge of the air bubbles is suppressed to be small. SOLUTION: A printer includes an inkjet head 3 ejecting a liquid droplet, a sub tank 4 supplying ink to the inkjet head 3, and a suction pump sucking the air bubbles in the sub tank 4 together with the ink. Furthermore, a movable member 70 is arranged in a vertical channel 61 in the sub tank 4. When the movable member 70 stands by the upper end 76 of the vertical channel 61, the ink flowing out from an ink reservoir chamber flows to the downstream side of the movable member 70. When the movable member 70 separates from the upper end 76 of the vertical channel 61 to the downstream side, it peels the air bubbles 80 from the upper end 76 of the vertical channel 61.

摘要： PROBLEM TO BE SOLVED: To prevent an excessive pressure from being applied to a gas permeable film when a gas is sucked through the gas permeable film. SOLUTION: An air chamber which communicates with an ink reservoir via the gas permeable film is formed above the ink reservoir in a sub tank to which the ink from a main tank is supplied. Gas-liquid separation in the ink reservoir can be executed via the gas permeable film by making a suction pump suck the air chamber, so that inflow of the air to an inkjet head is suppressed. A pressure control unit 90 is installed between the air chamber and the suction pump. The pressure control unit 90 has an opening 91c which communicates with the outside. A valve 92 releases the opening 91c when the pressure in a pressure control chamber 91 becomes lower than a predetermined value. Thus the excessive pressure is prevented from being applied to the gas permeable film when the pressure in the air chamber becomes lower than a predetermined value. COPYRIGHT: (C)2009,JPO&INPIT
摘要翻译：要解决的问题：为了防止当通过气体渗透膜吸入气体时，过大的压力被施加到透气膜上。解决方案：通过气体渗透膜与储墨器连通的空气室形成在供给来自主罐的墨水的副罐中的墨水容器的上方。通过使抽吸泵吸入空气室，可以通过透气膜进行储墨器中的气液分离，从而抑制空气向喷墨头的流入。压力控制单元90安装在空气室和抽吸泵之间。压力控制单元90具有与外部连通的开口91c。当压力控制室91中的压力变得低于预定值时，阀92释放开口91c。因此，当空气室中的压力变得低于预定值时，防止过大的压力施加到透气膜。版权所有（C）2009，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To miniaturize a inkjet printer by narrowing its width.
SOLUTION: A movable platen 34 is provided alongside of a platen 12 and is switched from a first rotating position where a wiper 36 faces upward to a second rotating position where a movable rib 38 faces upward by rotation centered around a revolving shaft 34a. A tip of the wiper 36 at the first rotating position is disposed at a position to contact a nozzle 18 so as to be utilized for cleaning of the nozzle 18. Moreover, the movable rib 38 at the second rotating position is upward and disposed side by side with a rib 14 so as to support a paper 10 when the paper 10 passes on the movable rib 38. Since the space alongside the platen 12 is shared by the wiper 36 at the first rotating position and the movable rib 38 at the second rotating position 38, the width of the inkjet printer 1 can be made narrower for the space shared.

摘要： PROBLEM TO BE SOLVED: To provide a liquid droplet ejecting apparatus which can efficiently and surely carry out the recovery action for nozzles by a positive pressure purge system while a consumption amount of liquid is suppressed, by a simple constitution.
SOLUTION: At the normal time, a pressing roller 14 is present at a retreat position, and a mesh press member 32 is present at a position of the rest state (the first STEP). The mesh press member 32 is a plate-like member with a plurality of ink passages (holes) formed in the shape of a mesh. When the recovery action is started, first, the pressing roller 14 descends to approach a sub tank 31 and is fixed (the second STEP). Thereafter, an elastic supporting member 35 at an upper part of the sub tank 31 contacts the pressing roller 14 by the movement of a carriage 4. The elastic supporting member 35 is elastically deformed to sink downwards when receiving a load from the pressing roller 14. In consequence, the mesh press member 32 is pressed to move to the downstream side (the third STEP). The downstream side is pressured by this movement, whereby ink, foreign substance and the like are discharged from the nozzle 37.
