Abstract
A main body (100A) includes a second movable member (110A) that is movable and that, has a first recess portion (123). The second movable member (110A) is moved from a first position where a first projecting portion (80a) of a first cartridge (70a) can enter a first recess portion (123) to a second position by a movement of the first projecting portion (80a), thereby allowing a second cartridge (70A) to be moved to an attachment position of the main body (100A). The second movable member (110A) also allows a third projecting portion (80A) of a second cartridge (70A) to enter the first recess portion (123) at the first position. The second movable member (110A) is moved to the second position when the third projecting portion (81A) enters the first recess portion (124), thereby allowing the second cartridge (70A) to be moved to the attachment position.
