Abstract: An ink jet type recording apparatus comprises a connection member which has a passage for leading ink to a recording head from an ink cartridge. In the passage, a valve member having a magnetic body is provided. A rotation member has a permanent magnet and is rotatable between a first position and a second position. When the rotation member is located in the first position, an attraction that can move the valve member in an opening direction of the passage acts between the magnet and magnetic body, and hence, the valve member opens the passage. When the rotation member is located in the second position, the attraction that can move the valve member does not act between the magnet and magnetic body, and hence, the valve member closes the passage.

Abstract: A liquid container includes: a container body that is detachably mounted to a container mounting portion of a liquid consuming apparatus and includes a liquid containing portion storing a liquid; a connection port that is provided in the liquid containing portion and delivers the liquid; a liquid delivery portion that is provided in one surface of the container body to supply the liquid to the liquid consuming apparatus; and a plurality of positioning means into which, when the container body is mounted to the liquid consuming apparatus, a plurality of positioning members that are provided on the container mounting portion at positions facing the one surface are fitted, thereby positioning the container body, wherein the liquid delivery portion is provided close to any one of the plurality of positioning means.

Abstract: A liquid storage container includes a liquid containing body that is formed of a flexible film and contains liquid therein; a liquid lead-out member connected to the liquid containing body; and a spacer member disposed in the liquid containing body. The liquid containing body deforms in a direction in which inner wall surfaces of the flexible film facing each other are brought into contact with each other at the time of reduction in the remaining amount of the liquid as the inside liquid is taken out through the liquid lead-out member, and the spacer member regulates contact between parts of the inner wall surfaces of the flexible film facing each other at the time of reduction in the remaining amount of the liquid to thereby form a remaining liquid space where liquid remains.
