摘要： The back pressure of an ink tank is controlled. A porous body is arranged inside the ink tank, the lower end of the porous body contacts an ink, and the ink ascends inside the porous body due to a capillary force. The upper end of the porous body is not immersed in the ink, and a maximum ascending force acts upon the ink stored in the ink tank. Therefore, the ink does not leak from a discharge head located lower than the ink tank. Further, because the ink is accumulated under the porous body and the amount of the ink contacting the porous body is small, components of the ink are less susceptible to deterioration.
摘要翻译：控制墨水罐的背压。多孔体设置在墨槽的内部，多孔体的下端与油墨接触，油墨由于毛细管力而在多孔体的内部上升。多孔体的上端没有浸入墨水中，并且最大上升力作用在储存在墨水罐中的墨水上。因此，墨水不会从位于低于墨水罐的排出头泄漏。此外，由于油墨积聚在多孔体下面并且与多孔体接触的油墨量少，所以油墨的成分不易劣化。

摘要： The backing pressure of an ink tank is controlled. The ink tank is connected to a pressure control apparatus. The pressure control apparatus has first and second check valves. When the internal pressure of the ink tank becomes smaller than that of outside atmosphere by a first predetermined pressure or more, the first check valve is switched into an open state to connect the outside atmosphere and the ink tank. To the contrary, when the internal pressure of the ink tank becomes larger than that of outside atmosphere by a second predetermined pressure or more, the second check valve is switched to an open state to connect the ink tank with the outside atmosphere. Therefore, the internal pressure of the ink tank is controlled precisely enough to stabilize the meniscus.

摘要： Vibration is prevented from being transmitted via a common ink chamber or a fixed substrate. A porous member is disposed between the common ink chamber and a pressure generation chamber so that a discharge liquid passes through the interior of the porous member to move from the common ink chamber to the pressure generation chamber. Vibration generated in one pressure generation chamber is attenuated through the porous member when the vibration is transmitted to another pressure generation chamber via the common ink chamber; and thus, no cross-talk is generated. Furthermore, when piezoelectric vibrators having different lengths are mounted on the same fixed substrate and have the resonance frequencies different from each other, vibration is not transmitted to another pressure generation chamber via the fixed substrate and the piezoelectric vibrator; and therefore, the cross-talk is much less likely to be generated.

摘要： Vibration is prevented from being transmitted via a fixed substrate. In order to set the resonance frequencies of the vibration of piezoelectric vibrators to be different from each other, the piezoelectric vibrators having different lengths are attached to the same fixed substrate. Even if residual vibration of a pressure generation chamber, which is expanded/contracted by a piezoelectric vibrator to which a voltage is applied, is transmitted to the fixed substrate; and even if the vibration is transmitted to another piezoelectric vibrator via the fixed substrate; another piezoelectric vibrator does not vibrate because the resonance frequencies between the piezoelectric vibrators are different from each other. Consequently, the pressure generation chamber in contact with the piezoelectric vibrator is not expanded or contracted by the vibration.
摘要翻译：防止振动通过固定基板传递。为了将压电振动器的振动的共振频率设定为不同，将具有不同长度的压电振动器安装在同一固定基板上。即使由施加有电压的压电振动器进行膨胀/收缩的压力产生室的残留振动传递到固定基板; 并且即使振动经由固定基板传递到另一个压电振动器; 另一个压电振动器由于压电振动器之间的谐振频率彼此不同而不振动。因此，与压电振动器接触的压力产生室不会因振动而膨胀或收缩。
