PROBLEM TO BE SOLVED: To reduce costs by storing a recording material or a holding member holding the recording material in a box-shaped case body of a cartridge, and setting a lid member for covering an opening part of the case body and a pin member for identifying a color and a type of the recording material. SOLUTION: In a cartridge of each color of yellow, magenta, cyan and black, an opening part of a box-shaped case body 12 in which an ink bag holding ink as a recording material is stored is covered with a lid member 13, and a pin member 14 for identifying a color and a type of the recording material is set to the case body 12. The pin member 14 has four pin holes 16 formed to an upper face of the case body 12 and is pressed into the pin hole 16 corresponding to the color of the stored ink. Parts are thus shared to decrease costs. Investing in molds and jigs can be remarkably reduced. |
