摘要： An ink supply system which includes an ink jet head for discharging ink and an ink tank retaining ink to be supplied to the ink jet head through a passage. A negative pressure generating container is provided along the passage, and generates negative pressure by a restoring force at the time of being deformed. With the ink supply system thus structured, it becomes possible to perform stable recording, because the fluctuation of flow resistance due to the fluctuation of discharge amount is made smaller, and also, there is almost no fluctuation of pressure along the carriage operation. Also, the retaining amount of ink becomes suitably greater for the performance of higher speed printing, and the replacement of ink tanks is possible, while ink still remains in the negative pressure generating container, hence making it possible to essentially prevent a complete ink depletion.

摘要： To provide a recording liquid feed path, recording liquid container, and recording liquid feed device having the same, as well surface modifying method for the recording liquid feed device to feed efficiently a recording liquid for ejection through a feed tube. If the interior of the feed tube is not rendered hydrophilic as shown in FIG. 3A, air which has passed through a wall of the feed tube forms a bubble, which bubble adheres to an inner surface of the feed tube and obstructs a flow of the recording liquid. But if the inner surface of the feed tube is rendered hydrophilic to form a hydrophilic surface as shown in FIG. 3B, the recording liquid is conducted along the hydrophilic surface at the inner surface portion of the feed tube with the bubble adhered thereto, so that the adhesion area of the bubble to the feed tube inner surface is reduced and the bubble floats from the inner surface. Consequently, when the recording liquid is fed, the bubble can be removed easily by the flow of the recording liquid and thus the flow of the recording liquid can be prevented from being obstructed by the bubble.

摘要翻译： 为了提供一种记录液体供给路径，记录液体容器和具有该液体供给装置的记录液体供给装置，以及用于记录液体供给装置的表面改性方法，用于有效地供给通过进料管喷射的记录液体。 如图4所示，如果进料管的内部没有变成亲水性的话。 如图3A所示，已经通过供给管的壁的空气形成气泡，该气泡粘附到进料管的内表面并阻碍记录液的流动。 但是，如图4所示，如果进料管的内表面被亲水化以形成亲水表面。 如图3B所示，记录液体在进料管的内表面部分处沿着亲水表面传导，气泡粘附在其上，使得气泡与进料管内表面的粘合面积减小，并且气泡从内表面漂浮 。 因此，当记录液体被供给时，可以通过记录液体的流动容易地去除气泡，从而可以防止记录液体的流动被气泡阻挡。
