An ink cartridge which is detachably mountable to a liquid ejection type recording device including a liquid ejecting head for ejecting liquid onto a recording material while scanning the recording material in a direction crossing with a feeding direction of the recording material, and a recovery unit for sucking the liquid through a nozzle of the liquid ejecting head. The ink cartridge includes a receiving portion for receiving the liquid discharged from the liquid ejecting head by the recovery unit; a liquid containing portion for accommodating the liquid to be supplied to the liquid ejecting head; and a connecting portion for connecting the receiving portion and the suction recovery unit, wherein the connecting portion is disposed at a position upstream of a front end surface portion of the ink cartridge with respect to an inserting direction in which the ink cartridge is inserted into the liquid ejection type recording device.

A joint member is made of an elastic member whose cross sectional shape is an almost M-character shape and which has: an inserting portion formed with an opening portion and a slit; an outer edge portion as an outer peripheral portion of the joint member; and a supporting fixing portion for coupling the inserting portion and the outer edge portion on the upper portion side. A cross sectional shape of an opening of the opening portion is a shape of a circular cone frustum in which the opening and a bottom surface are coupled via an inclined surface. The slit is formed in the rectangular bottom surface. The joint member is sandwiched between a casing and a pressing plate. The inserting portion and the supporting fixing portion exist in planes which are different in the inserting direction of a liquid supply needle.

The present invention solves problems attributable to color mixing occurring at a region where an ink container containing three or more different inks and an inkjet printing head are connected as a result of repetition of connection and disconnection of the components. An ink cartridge has a joint section which is connected to a printing head unit when the inks are supplied to the printing head unit. The printing head unit performs printing by ejecting the cyan, magenta, and yellow inks. At the joint section, a supplying part for the cyan ink, a supplying part for the magenta ink, and a supplying part for the yellow ink are arranged in the order listed. The interval between the yellow ink supplying part and the magenta ink supplying part is greater than the interval between the cyan ink supplying part and the magenta ink supplying part.

The present invention makes it possible to improve the alignment accuracy of the joint section of an ink cartridge with an ink supply route of an inkjet head. Based on this, the present invention provides an ink cartridge capable of preventing ink leakage with high reliability and constructed inexpensively in a reduced size and particularly suitable for a pit-in system. To attain this, distance (L1) is set to be shorter than distance (L2), where the distance (L1) is the one between a joint section (145) positioned in the proximity of a front surface (1A) of an ink cartridge (1) and an engage reference portion (135) serving as a reference position when the ink cartridge (1) is installed in the inkjet printing apparatus; and the distance (L2) is the one between the front surface (1A) of the ink cartridge (1) and the engage reference portion (135).
