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.
摘要翻译：用于在主墨水盒一侧补充墨水的端口前进，并且管体主体的鼻端或尖端进入副墨槽侧面的墨补充口。当管体主体中的阀体和副油墨罐侧面的阀被彼此挤压时，通过阀体打开连通口。当管子的主体进一步插入墨水补充口时，阀与衬垫的突出部分分开，并且其间的间隔开始变宽。在这个阶段，由于垫圈的唇部不与管的主体的外周部分接触，所以墨水通道向大气开放，留在或附着在外周部分上的墨水或墨水补充口的内部被吸收到副墨罐染料中，副墨盒中的负压。即，本发明提供一种能够可靠地防止油墨补充引起的油墨污染的墨水补充装置和设置有墨水补充装置的喷墨记录装置。

摘要： The present invention provides an ink jet recording apparatus which can prevent problems such as image defects caused by shortage of ink, and decreases in the printing speed from occurring. When execution of a print job is instructed, a printing processing for the print job is started. The number of pixels which have been actually printed is added to a current pixel count C1, and it is determined whether or not the print job is finished. When it is determined that the print job is finished and the pixel count C1 exceeds a predetermined number of pixels X1, an ink supply unit is controlled so that ink of a predetermined proportion A (%) of the amount of ink used, which amount corresponds to the pixel count C1, is supplied to a sub-ink tank.

摘要： A main ink chamber with a through-hole contains a capillary member. An intermediate ink chamber is provided on the side wall of the main ink chamber. A path communicatively interconnects the main ink chamber and the intermediate ink chamber. A second meniscus forming member is disposed in a joint port, to thereby prevent ink leakage. In a print mode, ink flows from the main ink chamber to the joint port, through a meniscus forming member that is disposed in the through-hole. Air bubbles mingled into the ink move along the slanting upper wall of the path by their buoyant force, and are accumulatively stored in the upper part of the intermediate ink chamber. When ink is reduced to zero in the main ink chamber, air bubbles are introduced into the intermediate ink chamber through the meniscus forming member. As a result, the liquid level of the intermediate ink chamber is quickly reduced, thereby indicating a state that ink is used up.

摘要： An ink jet printer is disclosed which, only when ink is to be supplied, supplies ink from a main tank disposed outside a carriage and which can effect the supply of ink stably without the leakage of ink. When it is detected by an ink level sensor that the ink level in a second ink chamber of an ink tank has become lower than a predetermined position, pipes in ports are inserted respectively into slit valves provided in the second ink chamber. Then, by operating a pump, the air present in the second ink chamber is discharged by suction to increase a negative pressure in the second ink chamber, allowing ink to be supplied from a main tank into the second ink chamber. Thus, since the supply of ink is performed by a negative pressure, it is possible to prevent the leakage of ink from the portion where the pipe is inserted into the slit valve.

摘要： The present invention provides a liquid jet printing head, a method of manufacturing the same, and a liquid jet printing apparatus, which allow stable, high speed, and continuous printing. A liquid jet printing head provides an inflow of liquid from an inlet to a common chamber, then along with the surface of heating elements of a heating element substrate and with a wall of a housing to separate channels. Liquid drops will be ejected by heating the heating elements. Since liquid may flow linearly from the inlet to the separate channels in accordance with the present invention, smooth flow promotes evacuation of bubbles through a nozzle, while cooling the heating element substrate with liquid flowing along with the substrate. The present invention provides thereby stable printing with high speed, continuous ejection (printing) of liquid drops.

摘要： Considering the differential pressure .DELTA.P between pressures applied to both faces of a meniscus formation member, the differential pressure .DELTA.P becomes the maximum when an ink supply unit is left standing with the meniscus formation member placed upward. At this time, water head PH of ink attempting to fall due to gravity is applied to the inner face of the meniscus formation member in the same direction as negative pressure PR of a capillary member. Thus, the differential pressure .DELTA.P becomes .DELTA.P=PR+PH. The bubble point pressure PB of the meniscus formation member is set greater than the maximum value of the differential pressure, .DELTA.P=PR+PH, whereby air does not enter an ink tank through the meniscus formation member.
摘要翻译：考虑到施加到弯液面形成构件的两个面上的压力之间的压差DELTA P，当向上放置弯液面形成构件而使供墨单元立起时，压差DELTA P变为最大值。此时，试图由于重力而下降的油墨的水头PH以与毛细管构件的负压PR相同的方向施加到弯液面形成构件的内表面。因此，压差DELTA P变为DELTA P = PR + PH。弯液面形成构件的泡点压力PB被设定为大于压差的最大值DELTA P = PR + PH，由此空气不会通过弯液面形成构件进入墨罐。

摘要： The present invention provides an inkjet recording head cartridge and an inkjet recording apparatus that have a simple structure and high reliability. Since individual flow passages in which ink emission orifices are formed are communicated directly with a rectangular ink supply chamber, it is prevented that a bubble of such a size as to cause printing defects rises through an ink supply chamber and blocks the individual flow passages. Also, since ink heated within the ink supply chamber is moved upward to the ink tank chamber by convection and grows an air lump sealed beforehand, it is prevented that a bubble will grow in the ink supply chamber. Furthermore, by allocating a large cross-sectional area to the ink supply chamber, it is prevented that meniscus oscillation of the ink emission orifices is amplified by pressure oscillation caused by ink emission and causes a printing defect. Therefore, reliable printing can be performed with a simple construction.
