摘要： An ink jet cartridge comprises an ink jet head unit (100) for discharging the ink, and an ink tank unit (200) having an ink supply port (209) for supplying the ink to the ink jet head unit. The ink tank unit has a partition portion (215) for partitioning between an ink storing portion (204) for storing the ink to be supplied to the ink jet head unit and a negative pressure generating member receiving portion (203) having a negative pressure generating member. The ink supply port (209) is provided on the negative pressure generating member receiving portion (203). And the partition portion (215) has an ink communicating portion at an end portion of the partitioning portion on the side of the negative pressure generating member receiving portion where the ink supply port (209) is provided, and makes contiguous the ink storing portion and the negative pressure generating member receiving portion in a movement direction of the ink tank unit (200) when discharging the ink.

摘要： A length (c) of a melamine foamed block (12) to be accommodated in an ink tank housing (11) as measured in the longitudinal direction is dimensioned to be larger than a length (C) of the ink tank housing (11) as measured in the longitudinal direction. Thus, while the foamed block (12) is accommodated in the ink tank housing (11), it is compressed in the direction orienting toward an ink feeding port (13) from which ink is fed to a printing head (14), i.e., in the ink feeding direction. Consequently, the ink retaining force induced by the capillary force is not intensified in the compressing direction of the melamine foamed block (12), resulting in an ink feeding capability of the printing head (14) being improved. On the contrary, the ink retaining force effective at a right angle relative to the compressing direction of the melamine foamed block (12) is intensified.
摘要翻译： 在长度方向上测量的容纳在墨罐壳体（11）中的三聚氰胺泡沫块（12）的长度（c）的尺寸设定为大于墨罐壳体（11）的长度（C），如 在纵向测量。 因此，当发泡块（12）容纳在墨罐壳体（11）中时，其沿着朝向从墨供给到印刷头（14）的供墨口（13）的方向被压缩，即， 在供墨方向。 因此，在三聚氰胺发泡块（12）的压缩方向上由毛细管力引起的油墨保持力没有增强，导致打印头（14）的供墨能力得到改善。 相反，加强了相对于三聚氰胺发泡块（12）的压缩方向成直角有效的油墨保持力。

摘要： A recording head comprises an ink container (IJC), an energy generating device (91) for discharging ink from the ink container, an ink discharge section corresponding to the energy generating device and a covering member that covers the ink discharge section and an atmosphere-communicating opening for the ink container, wherein when the recording head is out of recording, a small opening communicating with the atmosphere-communicating opening, or a valve member (22) capable of opening or closing in accordance with an internal pressure change, or an internal pressure change-absorbing member capable of absorbing an internal pressure change by changing its volume is provided on said covering member at a position corresponding to the atmosphere-communicating opening.
