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 printer designed to make users free from any danger when an inktank is replaced and to prevent ink from leaking out when the inktank is detached. The joint part of an inktank is pressed against the ink guide of a print head to couple the inktank and the print head together, so that ink is supplied from the inktank to the print head. The joint part is supplied with a porous material. When the inktank is attached, the porous material is compressed and contained in the joint part. When the inktank is detached from the print head, the volume of the porous material increases thereby raising its porosity. The ink remaining in the joint part is absorbed by the porous material whose porosity has been raised, so that ink is prevented from flowing out in the vicinity of the joint part when the inktank is removed.
摘要翻译：一种墨水打印机，旨在使用户在更换墨水时不会有任何危险，并防止墨水分离时墨水泄漏。墨槽的接合部分被压靠在打印头的墨水引导件上，以将墨槽和打印头连接在一起，使得墨水从墨水池供应到打印头。接头部分配有多孔材料。当安装墨槽时，多孔材料被压缩并包含在接合部分中。当墨水从打印头分离时，多孔材料的体积增加，从而提高其孔隙率。残留在接合部分中的油墨被孔隙率升高的多孔材料吸收，从而防止墨水在去除墨水时在接合部分附近流出。

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： A recording apparatus having a print head for printing characters on a medium and an ink tank for holding ink to be supplied to the print head. The ink tank includes an ink chamber having an ink holding member and an ink supplying port. A first meniscus forming member is located in the ink supplying port so as to be in communication with the ink holding member. The print head includes an ink introducing port for receiving ink from the ink tank and a second meniscus forming member located in the ink introducing port. When the ink tank is attached to the print head, the ink introducing port is coupled with the ink supplying port. An ink passing member is located in the portion where the ink introducing port is coupled with the ink supplying port. The ends of the ink passing member are in contact with the first meniscus forming member and the second meniscus forming member. The ink passing member is subject to only minor changes in volume upon contact with ink.

摘要： A joint part of an ink tank has a connection part capillary member. A filter is placed at the tip of an ink introduction part on the side of a recording head. The ink tank is connected by bringing a face of the filter into contact with the connection part capillary member; liquid connection is made without entry of air. At this time, a force of pressing the connection part capillary member against the inside of the ink tank occurs. However, since the connection part capillary member is provided with a presser part on the rear side, the presser part absorbs the press pressure and the contact state is stable, preventing the connection part capillary member from being detached to the inside of the ink tank. Additionally, the ink tank has a seal material for sealing the ink supply hole in a state in which the tank joint part is detached from the recording head joint part.

摘要： An elastic jointing member 22 with an umbrella-like portion with an opening and a flat part is provided in a jointing portion between a recording head 21 and an ink tank 1. When the ink tank 1 is attached to the recording head 21, the umbrella-like portion of the elastic jointing member 22 is pressed against the ink tank and elastically deformed inward. As a result, an ink passage is formed which is airtightly sealed. In the process of pressing the umbrella-like portion against the ink tank, the umbrella-like portion comes in contact with the flat part, to thereby prevent air from staying in the ink passage. Protrusions or grooves may be provided between the umbrella-like portion and the flat part. With the protrusions or the groove, the umbrella-like portion is not glued to the flat part.

摘要： In an ink tank, there are provided a main ink chamber containing a capillary vessel member, and an intermediate ink chamber. When the ink is consumed, the ink held by capillary force of a capillary vessel member is supplied via a communication port from a joint port. The same amount of air as the amount of the consumed ink is conducted from the atmospheric communication port into the main ink chamber. The conducted air is supplied via a groove formed in a lid to an upper surface of the capillary vessel member. As a result, the air is entered into the capillary vessel member under better condition. In a plane portion of the lid, the ink is in contact with only the capillary vessel member, and the ink remaining this portion is reduced. Thus, the ink using efficiency is increased.

摘要： An ink tank 1 includes a main ink chamber 11 and a intermediate chamber 16. A second meniscus forming member 17 is provided in a joint portion 2 to be coupled with a printhead 3. A filter 22 is provided in an ink introducing portion 4 of the printhead 3, which is to be coupled with the ink tank 1. The open-space diameter of the second meniscus forming member 17 is selected to be equal to that of the filter 22. With such a construction, the number of foreign materials flowing from the ink tank 1 to the filter 22 is reduced. The result is to reduce a frequency of occurrence of the filter clogging and to elongate a normally operable time of the printer. A fluid resistance in the ink passage ranging from the filter 22 to the nozzle is high. Therefore, air that is left in the jointing portion flows through the second meniscus forming member 17 into the intermediate chamber 16 of the ink tank 1. Therefore, there is eliminated such an unwanted situation that air bubbles enter the printhead and given rise to defects in a printed picture.
