PROBLEM TO BE SOLVED: To smoothly and easily remove a cartridge through an opening from an inner space and ensure a superior operability when the cartridge is to be removed. SOLUTION: One side surface of a storing case comprised of an upper case 20 and a lower case 21 is formed such that the upper case 20 and the lower case 21 are properly slidingly contacted and rotated around one corner part, thereby a desired opening 34 capable of storing or discharging a cartridge 10 is formed. In this case, a cartridge pressing rib 35 arranged at the upper case 20 forcedly discharges the cartridge 10 stored in an inner space 27 toward the opening 34 and then the cartridge 10 is popped up from the inner space 27 through the opening 34 in a direction of an arrow I.
