The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "or/and" includes any and all combinations of one or more of the associated listed items.

Unless otherwise defined, terms of orientation such as "upper, lower, left, right, front, rear," and the like, as used herein, refer to the orientation as shown in the drawings. The remaining description, which is not specified with reference to the orientation of the drawings, is described with reference to the direction of gravity.

It should be noted that, since the present invention provides a plurality of matching relationships between the chip holder 100 and the ink cartridge body 200 and the chip 300, the following description of the structure will first use the ink cartridge as a main body, and the matching structure between the chip holder 100 and the ink cartridge body 200 will be clearly described.

Referring to fig. 1 to 6, an ink cartridge according to a first embodiment of the present invention includes a chip holder 100, a cartridge body 200, and a chip 300, wherein: the ink cartridge body 200 has a housing, the chip holder 100 is mounted on the housing of the ink cartridge body 200 and detachably connected thereto, and the chip 300 is mounted on the chip holder 100. When the ink cartridge is mounted to an image forming apparatus such as a printer, the ink cartridge is fixed to a cartridge holding portion of the image forming apparatus in a predetermined manner, and chip contact pins on the cartridge holding portion are made to reliably contact contacts on the chip 300, thereby enabling the ink cartridge to be recognized and driven by the image forming apparatus.

Referring to the coordinate system shown in fig. 1, the x-axis direction in the figure is defined as the width direction of the ink cartridge, the y-axis direction is defined as the length direction of the ink cartridge, and the z-axis direction is defined as the height direction of the ink cartridge; similarly, referring to fig. 2, the y-axis direction is defined as the thickness direction of the holder body 11, the x-axis direction is the width direction of the holder body 11, and the z-axis direction is the height direction of the holder body 11; further, referring to fig. 3 and 4, in the y-axis direction, the side of the cartridge body 200 mounted corresponding to the holder body 11 is a first side portion 21; the two side surfaces of the ink cartridge body 200 in the x-axis direction are a second side portion 22 and a fourth side portion 24, respectively, and the lower surface in the z-axis direction is a third side portion 23.

In addition, the meaning of "adjoining" in the present invention is similar to the meaning of the positional relationship between two faces having a common edge in a polyhedral structure. For example, considering the ink cartridge body 200 as a generally hexahedral structure, the first side portion 21 and the second side portion 22/the fourth side portion 24 and the third side portion 23 are all configured so-called "adjacent". However, in the present invention, the ink cartridge body 200 is not of a regular hexahedral structure, and there may be a bevel or the like at a position of an edge shared between two adjoining side portions, and thus "adjoining" merely defines the relative orientation between the side portions, and does not necessarily require that it satisfy the definition of adjoining in a geometric sense. Similarly, the first side 21, the second side 22, the third side 23, and the fourth side 24 are merely intended to refer to the respective orientations of the ink cartridge body 200.
