<p>PROBLEM TO BE SOLVED: To prevent a cover from being closed in a half-inserted state in which a cartridge is not mounted correctly, so as to stop supply of an ink to an image formation apparatus.SOLUTION: In a cover 10 on the side of the printer body, a protrusion-shaped part 11 opposing a cartridge 1 in a closed state is provided. In a state in which the cartridge 1 is mounted correctly, closing of the cover 10 causes the protrusion-shaped part 11 to enter a clearance 1a between a lock lever 6 and the upper surface of the cartridge 1 and can close the cover 10. If the cover 1 is to be closed in a half-inserted state of the cartridge 1, although entering the clearance 1a, the protrusion-shaped part 11 disturbs the descending of the lock lever 6, and the position of a rib 7 also does not descend and is kept in contact with a holder 5. The cartridge 1 cannot be pushed in further, preventing the cover 10 from being closed.</p> |
