PROBLEM TO BE SOLVED: To avoid a situation that a setting work is discontinued because of the insufficient engagement due to generation of engagement sound twice in a structure wherein an ink cartridge is fixed through engagement at two points to a holder. SOLUTION: A first engagement member 21 engages only after a second engagement member 22 engages. Moreover, the sound when a projecting part 32 of the second engagement member 22 engages with a recess part 109 as an engagement part is made smaller than the engagement sound by the first engagement member 21. The user is prevented from bringing the setting work of the cartridge to an end before the first engagement member 21 engages, that is, before both engagement members 21 and 22 engage.
