Abstract
An ink cartridge and an ink cartridge holder for maintaining the relative position between the information reading section of the ink cartridge holder and the information storing unit of the ink cartridge, which should be aligned accurately, even if the ink cartridge has instability to the ink cartridge holder due to the variation in each products. The ink cartridge which supplies ink to a recording apparatus includes: a substantially rectangular parallelepiped ink cartridge main body holding the ink; a connection electrode section provided on a part of a first side of the ink cartridge main body and including a connection terminal; an ink supply unit provided in a front surface which intersects the first wall; and a positioning section guiding a positioning member of the recording apparatus to the vicinity of the connection electrode on the front surface so that the positioning member opposes to the connection electrode section in the direction parallel with the connection electrode section.

11. An ink cartridge holder that receives an ink cartridge, where the ink cartridge is detachably mounted, where the ink cartridge has a connection electrode section of an information storing section located on a part of a first wall, and has an ink supply section located on a front wall which intersects the first wall, the ink cartridge holder comprising:
-
a holder main body including an opening face through which the ink cartridge is inserted, the front surface first, said holder main body holding the ink cartridge;
an information reading section including a connection electrode section within said holder main body, the information reading section being provided at a position corresponding to the connection electrode section of the information storing section of the ink cartridge so that, when the ink cartridge is mounted, the connection electrode section of the information reading section is in electrical contact with the connection electrode section of the ink cartridge; and
a positioning member extending from said holder main body toward said opening face, and positioned in the vicinity of said information reading section in a direction parallel with the first wall and the front wall of the ink cartridge so that, viewed in a direction perpendicular to a plane in which the first wall of the ink cartridge lies, when the ink cartridge is mounted, at least a portion of the positioning member overlaps at least a portion of the information reading section of the ink cartridge. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
