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.
摘要翻译：一种具有用于在介质上打印字符的打印头和用于保持要供应到打印头的墨水的墨盒的记录装置。墨水盒包括具有墨水保持部件和墨水供给口的墨水室。第一弯液面形成构件位于供墨口中，以与油墨保持构件连通。打印头包括用于从墨水罐接收墨水的墨水引入口和位于墨水引入口中的第二弯液面形成构件。当墨水盒附接到打印头时，墨水引入口与供墨口连接。油墨通过部件位于墨水引入口与供墨口连接的部分中。油墨通过部件的端部与第一弯液面形成部件和第二弯液面形成部件接触。油墨通过部件在与油墨接触时只能稍微改变体积。

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： 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.
摘要翻译：在记录头21和墨罐1之间的接合部分设置有具有开口和平坦部分的伞形部分的弹性接合构件22.当墨水罐1附接到记录头21时，伞弹性接合构件22的类似部分被压靠在墨盒上并向内弹性变形。结果，形成气密密封的油墨通道。在将伞状部压在墨水罐上的过程中，伞形部与平坦部接触，从而防止空气滞留在墨水通道中。可以在伞形部分和平坦部分之间设置突起或凹槽。通过突起或槽，伞状部分不会粘合到平坦部分。

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.
