    摘要： To accurately position and fix an ink cartridge on an ink cartridge mounting unit, a first engaging depression is formed in the bottom wall of the ink cartridge and a corresponding protrusion is formed in the mounting unit. Also, an ink supply port is formed in the bottom wall. When the ink cartridge is mounted on the mounting unit, the ink supply port is engaged first with an ink supply channel formed in the mounting unit and fluidly connected to the head unit. Then, the first engaging depression is brought into engagement with the corresponding protrusion in the mounting unit. A second engaging depression is further formed in the top. The engaging pawl of a locking arm engages the second engaging depression when the locking arm locks the ink cartridge to the head unit. Further, a pair of ribs is provided on the rear side wall of the ink cartridge. The ribs oppose each other with a prescribed interval. A corresponding protrusion protrudes from the head unit and fits into the space between the interval of the ribs when the ink cartridge is mounted in the head unit.

    摘要翻译： 为了将墨盒精确地定位和固定在墨盒安装单元上，在墨盒的底壁中形成第一接合凹部，并且在安装单元中形成相应的突起。 此外，在底壁中形成供墨口。 当墨盒安装在安装单元上时，墨水供应口首先与形成在安装单元中的墨水供应通道接合并且流体地连接到头部单元。 然后，第一接合凹部与安装单元中的相应突起接合。 第二接合凹陷进一步形成在顶部。 当锁定臂将墨盒锁定到头单元时，锁定臂的接合爪接合第二接合凹部。 此外，在墨盒的后侧壁上设置一对肋。 肋骨以规定的间隔相互对置。 当墨盒安装在头单元中时，对应的突出部从头单元突出并且配合到肋的间隔之间的空间中。
