Abstract

An ink container for supplying through an ink supply port ink accommodated in a main body of the container, the ink container including a substrate mounted on a surface of the main body of the container, and a contact portion and a storing element electrically connected with contact the portion, the contact portion and the storing element being provided on the substrate, Characterized In That the contact portion is disposed at a position more remote from the ink supply port than the storing element.

Claims

1. An ink container for supplying through an ink supply port ink accommodated in a main body of said container, said ink container including a substrate mounted on a surface of the main body of said container, and a contact portion and a storing element electrically connected with contact said portion, said contact portion and said storing element being provided on said substrate, the improvement residing in that:

said contact portion is disposed at a position more remote from said ink supply port than said storing element.

2. An ink container according to claim 1, wherein said contact portion is disposed on an outer surface of said substrate, and said storing element is disposed on an inner surface of said substrate.

3. An ink container according to claim 2, wherein the position of said contact portion and the position of said storing element are at least partly overlapped with each other as seen in a direction perpendicular to the outer surface.

4. An ink container according to claim 2, wherein the position of said contact portion is deviated from a center of the outer surface away from said ink supply port, and wherein the position of said storing element is deviated from a center of the inner surface toward said ink supply port.

5. An ink container according to claim 2, wherein a surface of said main body of said container is provided with a recess engaged with said storing element.

6. An ink container according to claim 5, wherein said surface of said main body of said container is provided with a cap mounting recess to which a cap is mountable to seal said ink supply port, and wherein said cap mounting recess is continuous with said recess engaged with said storing element.

7. An ink container according to claim 1, wherein the main body of said container is mountable to a recording device through a holder having a recording head capable of ejecting the ink.

8. An ink container according to claim 7, wherein said main body of said container is mountable to said holder with rotation.

9. An ink container according to claim 2, wherein the main body of said ink container contains the ink.

10. An ink container holder to which an ink container for supplying through ink supply port ink accommodated in a main body of a container, said ink container including a contact portion and a storing element electrically connected with the contact portion, said ink container holder comprising an ink introduction opening for receiving ink from said ink container through said ink supply port and a contactable portion for electrical connection with said contact portion, the improvement residing in that:

said ink container including a substrate mounting to a surface of the main body of the container, a storing element provided on a back side of the substrate;

said contact portion is disposed on an outer surface of said substrate at a position more remote from said ink supply port than said storing element, wherein said contactable portion is contacted to said contact portion after contacting to said outer surface when said ink container is mounted to said holder.

11. An ink container holder according to claim 10, wherein the ink container is mountable to said ink container holder with rotation of said ink container.
