Abstract
A cartridge attachment structure includes: a cover whose one end is attached to a pivot shaft for opening and closing a storage space; a support member attached to the pivot shaft and supporting a cartridge; and a pair of lifting-up members attached to the cover such that the cartridge can be sandwiched along the side surface of the cartridge. A groove is formed on each of the opposing inner surfaces of the lifting-up members to receive a projection 16 formed on the side surface of the cartridge. The groove is curved such that the bottom surface of the cartridge moves away from the support member when the protrusion slides along the groove as the cover rotates about the pivot shaft.
