PRINTING FLUID CARTRIDGE, PRINTING APPARATUS, AND USE OF PRINTING FLUID CARTRIDGE

摘要

A printing fluid cartridge includes a front face oriented toward a first direction, a printing fluid supply portion positioned at the front face, a rear face positioned opposite the front face and oriented toward a second direction opposite the first direction, at least one electrical interface positioned between the front face and the rear face, and an engagement surface facing in the second direction. The at least one electrical interface is offset from the printing supply portion with respect to a third direction perpendicular to the first direction and the second direction. The at least one electrical interface is positioned closer to the front face than the engagement surface is, and the at least one electrical interface and the engagement surface intersect a plane which is parallel with the first direction, the second direction, and the third direction.

主权项

1. A printing fluid cartridge comprising:
a front face oriented toward a first direction; a printing fluid supply portion extending in the first direction; a rear face positioned opposite the front face and oriented toward a second direction opposite the first direction; at least one electrical interface disposed between the front face and the rear face, the at least one electrical interface being offset from the printing supply portion with respect to a third direction perpendicular to the first direction and the second direction; an engagement surface; an opening positioned further in a fourth direction than the at least one electrical interface, wherein the fourth direction is opposite to the third direction, and the opening is open to an exterior of the printing fluid cartridge in the first direction and is configured to receive a rod extending in the second direction; and a spring-loaded member facing the opening in the first direction and configured to move in the second direction in response to contacting the rod received in the opening, wherein the at least one electrical interface and the engagement surface intersect a particular plane which is parallel with the first direction, the second direction, the third direction, and the fourth direction.
