Inner wall surfaces of the pair of side walls which are continuously and integrally extended from an opening of an ink tank and confront each other in an ink cartridge have a flat shape. In each side wall, a thickness of a lower portion of the wall is set to be smaller than a thickness of an upper portion. Each cartridge is mounted with the lower portion of the ink tank on a cartridge mount portion between respective partition walls formed on a bottom plate of a head holder. Further, the width of the upper portion of the cartridge is larger than the width of the lower portion. Therefore, the ink cartridge cannot be mounted on the cartridge mount portion incorrectly. <IMAGE> |
