Abstract: A cartridge includes a printing material containing section, a plurality of printing material supply ports, and a branch communicating section. The printing material containing section is configured and arranged to contain a printing material. A detection region is configured as a part of the printing material containing section to detect the printing material in the printing material containing section. The plurality of printing material supply ports are configured and arranged to supply the printing material from the printing material containing section. The branch communicating section branches into the plurality of printing material supply ports respectively and communicates the detection region and the plurality of printing material supply ports to distribute the printing material to the plurality of printing material supply ports respectively.

Abstract: A liquid accommodating container in which a fiber member and a liquid are accommodated has a fiber ratio of the fiber member is 5% or more to 30% or less, a fiber diameter of the fiber member is 10 ?m or more to 50 ?m or less, a volume average particle diameter (D50) of a pigment included in the liquid satisfies a condition of 50 nm<D50<150 nm.

Abstract: Cartridges 4 and 5 are configured, such that first convex ribs 428a and 528a abut against second wall surfaces 762 of cartridge engagement wall surfaces 760 inclined with respect to a bottom wall 712 of a cartridge attachment structure 7 and move in friction with the second wall surfaces 762. Such abutting and moving causes contact portions of terminals 412 and 512 of circuit substrates 410 and 510 of the respective cartridges 4 and 5 to come into contact with electrode assemblies 810 of a carriage 8. This configuration enhances the reliability of electric connection between a contact portion, such as a circuit substrate, of a liquid supply unit and an electrode assembly, such as contact pins, of a carriage in the course of attachment.
