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.
