Patent ID: 8651639

Claim:
A printing fluid cartridge comprising: at least one electrical interface configured to be electrically connected to at least one contact; a light attenuating portion configured to attenuate light; a chamber configured to store printing fluid therein; a printing fluid supply portion configured to supply the printing fluid from an interior of the chamber to an exterior of the chamber; a front face oriented toward a first direction, wherein the printing fluid supply portion is positioned at the front face; and a rear face positioned opposite the front face and oriented toward a second direction opposite the first direction, wherein the at least one electrical interface is positioned between the front face and the rear face, and wherein the light attenuating portion is configured to attenuate light traveling in a third direction perpendicular to the first direction and the second direction, and the at least one electrical interface is accessible in a fourth direction perpendicular to the first direction, the second direction, and the third direction, wherein the at least one electrical interface comprises a first electrical interface, a second electrical interface, and a third electrical interface aligned and spaced apart from each other in the third direction, wherein the second electrical interface is positioned between the first electrical interface and the third electrical interface, and the at least one electrical interface and the light attenuating portion are positioned, such that the second electrical interface and the light attenuating portion intersect a plane which is parallel with the first direction, the second direction, and the fourth direction, and wherein a center of the second electrical interface and a center of the light attenuating portion are positioned on the plane which is parallel with the first direction, the second direction, and the fourth direction.
