PURPOSE:To prevent the adhesion of impurity to solid ink by simply and certainly replenishing an ink tank with the solid ink and preventing the exposure of the solid ink to the outside. CONSTITUTION:When ring outside key parts 30 are matched with replenishing hole key parts, a ring 18 is fixed to an ink tank and, when a cylindrical case 20 is rotated by the hand, the positioning lock locking the cylindrical case 20 and the ring 18 is released and the cylindrical case 20 becomes rotatable. Since the crossed protruding part 36 of the cylindrical case 20 is matched with the crossed hole part 16 of solid ink 10, the solid ink 10 and the cylindrical case 20 are integrally rotated. During a period when the cylindrical case 20 is allowed to make one revolution, the ink key parts 12 provided to the cylindrical outer peripheral part of the solid ink 10 are matched with the ring inside key parts 14 of the ring 18 and the solid ink 10 passes through an ink replenishing part to freely fall in the ink tank. |
