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 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： 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 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： 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。
