PROBLEM TO BE SOLVED: To shorten intervals between cartridges by providing a knob at one end part of an ink cartridge and arranging a plurality of ink cartridges such that the one end part will be stepwise when they are mounted on a mounting part. SOLUTION: A recessed finger hooking part 2d is provided in the rear on the right side face of a cartridge 2. More specifically, the finger hooking side of the finger hooking part 2d is formed on the side where one end part, i.e., the rear end part, does not face an adjacent cartridge 2. A plurality of such ink cartridges are mounted stepwise, in plan view, on a mounting part. Since the end parts of the cartridges 2 having the finger hooking part 2d are arranged stepwise, a finger can be hooked easily to the finger hooking part 2d using a space S1 formed on the side thereof and the cartridge 2 can be picked and drawn out easily without increasing the interval between the cartridges 2. |
