摘要： An inkjet recording device of the present invention includes an inkjet recording head, a first wiper, a first movement component and a control component. The inkjet recording head ejects ink droplets from a plurality of nozzles formed in a nozzle face. The first wiper abuts against the nozzle face and wipes the nozzle face. The first movement component relatively moves the first wiper, with respect to the nozzle face, along the nozzle face. The control component controls ejection of ink droplets from the nozzles and controls the first movement component. The control component moves the first wiper relative to the nozzle face while the control component causes ink droplets to be ejected from the nozzles at least toward the first wiper, causing the nozzle face to be wiped.

摘要： An ink jet recording apparatus according to the present invention comprises an ink jet recording head for ejecting ink drops and a differential pressure valve provided in an ink feeding line connected to the ink jet recording head, the differential pressure valve generating a head back pressure in the ink jet recording head when ejecting no ink drop. Thus, the degree of freedom for the position of arrangement of an ink reservoir such as an ink tank connected to the ink feeding line is remarkably increased. Accordingly, it is possible to realize an ink jet recording apparatus of reduced size.

摘要： A liquid droplet ejecting unit is disclosed wherein plural liquid droplet ejecting sub-units are provided which are arrayed in a direction substantially perpendicular to a conveying direction of a recording medium. Further, plural valves are provided which connect the respective liquid droplet ejecting sub-units and a liquid feed path. The valves comprise a valve body having an inlet port and an outlet port, and a floating member. The floating member is larger in radius than the inlet port and smaller in radius than the outlet port and has a lower specific gravity that the liquid. Thus, the floating member is floated in the liquid in the valve body and capable of closing the inlet port. An image forming apparatus using such a liquid droplet ejecting unit is also disclosed.

摘要： An ink supply device is provided in correspondence with a recording head unit. The recording head unit has a recording head that ejects ink drops onto a recording medium on the basis of image information. Additionally the recording head unit has a sub ink tank provided with an air communication hole. The ink supply device includes an ink supply unit that supplies ink to the sub ink tank by reducing pressure on the inside of the sub ink tank through a pressure reduction part. A sealing part at least implements sealing of the air communication hole while the ink supply unit is reducing the pressure inside the sub ink tank.

摘要： A fluid feed pump which prevents fluid from leaking or flowing back from a discharging side section into a suction side section when fluid sucked into the pump from the suction side section is to be fed into the discharging side section is disclosed. When a piston in a cylinder moves in a sucking/discharging direction, fluid flows into an inlet port side section in the inside of the cylinder through an inlet port while the inlet port side section and an outlet port side section of the inside of the cylinder are separated in an axial direction by a tubular enclosing member. Thereupon, since a lower portion of the tubular enclosing member is expanded in a radial direction to contact an outer circumferential face thereof in a water-tight condition with the inner face of the cylinder, the inlet and outlet port side sections of the cylinder are isolated in a high sealing condition from each other. Since the piston moves in the sucking/discharging direction while the inside of the cylinder is in the condition wherein the inlet and port side sections thereof are isolated from each other, fluid in the outlet port side section in the inside of the cylinder does not flow into the inlet port side section.
摘要翻译：公开了一种流体供给泵，其在从吸入侧部分吸入泵中的流体被送入排放侧部分时，防止流体从排出侧部分泄漏或回流到吸入侧部分。当气缸中的活塞在吸入/排出方向移动时，流体通过入口流入气缸内部的入口侧侧部分，而气缸内部的入口侧部分和出口侧侧部分通过管状封闭构件沿轴向分离。因此，由于管状封闭构件的下部在径向方向上膨胀，以与气缸的内表面在水密状态下接触其外周面，所以气缸的入口和出口侧部分被隔离在彼此处于高密封条件下。由于活塞在吸入/排出方向上移动，同时气缸的内部处于其入口侧和端口侧部分彼此隔离的状态，气缸内部的出口侧部分中的流体不流动进入入口侧部分。

摘要： A port for replenishing ink on the side of a main ink tank advances and the nose or tip end of a main body of a pipe enters an ink replenishing opening on the side of a sub ink tank. When a valve body in the main body of the pipe and a valve on side of the sub ink tank are pressed with each other, a communicating port is opened by the valve body. When the main body of the pipe is further inserted into the ink replenishing opening, the valve is separated from a projection portion of a gasket, and a space therebetween starts to be widened. At this stage, as a lip portion of the gasket is not in contact with an outer peripheral portion of the main body of the pipe, an ink channel is opened to the atmosphere, the ink which is remained in or adhered to the outer peripheral portion of the main body of the pipe or an inside of the ink replenishing opening is absorbed into the sub ink tank dye ti a negative pressure in the sub ink tank. Namely, the present invention provides an ink replenishing device which can reliably prevent ink dirt from being caused by ink replenishing and an ink jet recording apparatus which is provided with the ink replenishing device.
