Abstract
A main body includes a second movable member that is movable and that has a first recess portion. The second movable member is moved from a first position where a first projecting portion of a first cartridge can enter the first recess portion to a second position by a movement of the first projecting portion, thereby allowing a second cartridge to be moved to an attachment position of the main body. The second movable member also allows a third projecting portion of the second cartridge to enter the first recess portion at the first position. The second movable member is moved to the second position when the third projecting portion enters the first recess portion, thereby allowing the second cartridge to be moved to the attachment position.
