Printing fluid cartridge, printing apparatus, and use of printing fluid cartridge
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.
1. A printing fluid cartridge comprising:
a main body including a frame defining a chamber storing printing fluid, the frame having an engagement surface;
a printing fluid supply portion extending in a frontward direction, the printing fluid supply portion being positioned at the main body;
a bracket attached to the main body, wherein the bracket includes:
a front wall facing frontward, wherein the front wall of the bracket is formed with an opening,
a top wall facing upward,
a side wall orthogonal to the front wall and the top wall, and
wherein the frame includes an engagement portion engaging with the side wall of the bracket;
an IC board including a plurality of electrodes and configured to store data, the IC board being positioned frontward of the engagement surface on the bracket and the IC board being positioned on the top wall.
2. The printing fluid cartridge of claim 1 , wherein the opening being positioned frontward of the electrical interface.
3. The printing fluid cartridge of claim 1 , wherein the plurality of electrodes is positioned closer to the front wall of the bracket than the engagement surface is.
4. The printing fluid cartridge of claim 1 , wherein the side wall is formed with an opening, and the engagement portion is positioned in the opening.
5. The printing fluid cartridge of claim 1 , wherein the main body includes a protrusion protruding upward, the protrusion including the engagement surface, and at least a part of the protrusion is positioned upward relative to the plurality of electrodes.
6. The printing fluid cartridge of claim 1 , wherein the bracket includes a light attenuating wall.
7. The printing fluid cartridge of claim 1 , wherein the bracket includes a pair of guides extending from the top wall, and wherein the IC board is positioned between the pair of guides.
8. The printing fluid cartridge of claim 7 , wherein the pair of guides are extending rearward of the plurality of electrodes.
9. The printing fluid cartridge of claim 1 , wherein the plurality of electrodes and the engagement surface are exposed to the exterior of the printing fluid cartridge upwardly.
10. The printing fluid cartridge of claim 1 , wherein the printing fluid cartridge is formed with a recess between the bracket and the main body.
11. The printing fluid cartridge of claim 1 , wherein the printing fluid cartridge is configured to be inserted into a cartridge mounting portion, and the engagement surface is configured to receive a force for retaining the printing fluid cartridge in the cartridge mounting portion.
12. The printing fluid cartridge of claim 11 , wherein the engagement surface is configured to contact an engagement member of the cartridge mounting portion such that the printing fluid cartridge is retained in the cartridge mounting portion.
