The body includes a groove and a slit portion abutting against the groove. The first scraper portion is abutting against the slit portion. The cover includes a plate portion. The second scraper portion is abutting against the plate portion, wherein the position of the second scraper portion is corresponding to the first scraper portion. The air pressure through hole is disposed on the body, in communication with the groove, and adapted to connect an air pressure connection member to input air pressure. The side cover unit is adapted to form an ink storage space between the plate portion and the groove, and form an ink output slit between the slit portion and the plate portion.
