An ink cartridge attachment/detachment device (1) includes a cartridge holding mechanism (30) that holds an ink cartridge (11) upon insertion of the ink cartridge (11) by a first predetermined stroke, and a power transmitting and converting mechanism (32) that ensures pressing force required for loading the ink cartridge (11) by using rotation of a lever arm (163) and leverage principle, and converts the rotation of the lever arm (163) into movement of a second predetermined stroke (S) required for loading the ink cartridge (11) held by the cartridge holding mechanism (30). The power transmitting and converting mechanism (32) includes a first cam portion (172) for moving the cartridge holding mechanism (30) by the second predetermined stroke (S).
