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.
摘要翻译：具有通孔的主墨室包含毛细管构件。中间墨水室设置在主墨水室的侧壁上。通路连通主墨室和中间墨室。第二弯液面形成构件设置在接合口中，从而防止油墨泄漏。在打印模式中，油墨通过设置在通孔中的弯液面形成部件从主油墨室流向接头端口。混入墨水的气泡通过其浮力沿着倾斜的路径上壁移动，并且累积储存在中间墨水室的上部。当墨水在主墨水室中减少为零时，气泡通过弯液面形成构件被引入中间墨水室。结果，中间墨水室的液位迅速降低，从而表示墨水被用尽的状态。

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： An ink supply passage 16 has a large cross-sectional area and ink tanks 6 are connected to the top of the ink supply passage 16. An ink supply passage 17 is a flow passage shaped like a semicylinder and has a cross-sectional area equal to or smaller than the cross-sectional area of the ink supply passage 16. Even if bubbles are mixed into the ink supply passage 17, they adhere to the upper portion of the flow passage 17 and do not flow into lower corners, so that a flow passage can be provided and the ink flow is not hindered. Since an ink supply passage 19 connected to a head chip 4 has a small diameter, bubbles mixed into the ink supply passage 19 can be removed by maintenance for sucking ink forcibly. Bubbles mixed upstream are not transported to the ink supply passage 19 because of the flow rate difference caused by the cross-sectional area difference.
摘要翻译：供墨通道16具有大的横截面积，并且墨水罐6连接到供墨通道16的顶部。供墨通道17是形状类似于半圆柱形的流动通道，其横截面积等于或小于供墨通道16的横截面积。即使气泡混入供墨通道17中，它们粘附到流动通道17的上部并且不流入下角，使得流动可以提供通道并且墨流不受阻碍。由于连接到头部芯片4的墨水供应通道19具有小的直径，所以通过维护来强制吸入墨水可以去除与供墨通道19混合的气泡。由于由横截面积差引起的流量差，上游混合的气泡不会输送到供墨通道19。

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 ink 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 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： Ink-jet recording ink improved in releasability of bubbles and the like. The ink comprises water, a colorant and a water-soluble organic solvent. The surface tension of the ink at 20.degree. C. is higher than the surface tension of a composition which comprises the components for the ink except the colorant. Ink-jet recording is effected by making use of the ink and, for example, a heating system.
