  • Patent number: 11919316
    Abstract: 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.

  • Publication number: 20230182475
    Abstract: A liquid cartridge is configured to be inserted into a liquid consuming apparatus in a first direction along a horizontal direction against an urging force directed in a second direction opposite the first direction, and thereby to be mounted to the liquid consuming apparatus. The liquid cartridge is configured to pivot about a pivot center in the liquid consuming apparatus. The liquid cartridge includes a rear face, and the rear face includes a first portion and a second portion positioned further in an upward direction than the first portion. The first portion includes a portion positioned further in a downward direction than the pivot center, and the first portion is positioned further in the first direction than the second portion.
