Abstract

See full text

A cartridge 5 is mounted on a carriage 8. The carriage 8 includes liquid introducing parts 710m, 710c and 710y and a guide projection 723. The guide projection 723 is extended from between the liquid introducing parts 710m and 710c toward the liquid introducing part 710y. The cartridge 5 includes an ink supply port 507m connectable with the liquid introducing part 710m to supply magenta ink to the liquid introducing part 710m, an ink supply port 507c connectable with the liquid introducing part 710c to supply cyan ink to the liquid introducing part 710c, an ink supply port 507y connectable with the liquid introducing part 710y to supply yellow ink to the liquid introducing part 710y, and a first groove 580. The first groove 580 is extended from between the ink supply port 507m and the ink supply port 507c toward the ink supply port 507y to allow for insertion of the guide projection 723. This configuration suppresses diffusion of ink leaked from any of the liquid supply ports of the cartridge.
