Abstract: A method for assembling an ink supply section having a supply valve for allowing an ink supplying opening and an ink containing chamber to communicate with each other by allowing the ink containing chamber, the ink supplying opening and an ink supply needle to be in contact with each other, a seal member for closing the ink supplying opening and the ink containing chamber by allowing the supplying valve to be in contact, and an urging member for urging the supply valve to the seal member, wherein the method includes the steps of inserting the urging member into the ink supply section from the ink supplying opening, mounting the seal member onto the ink supplying opening and allowing the supply valve to be in contact with the seal member by the urging force of the urging member by inserting the supply valve from the insertion opening of the seal member mounted on the supplying opening in the step of mounting.

Abstract: An ink cartridge has pivotable levers connected to walls of a container, and both pawls and protruded guide portions formed on the levers. The pawls are engageable with an ink cartridge holder. The protruded guide portions contact the ink cartridge holder to move the levers in the opening direction. Further, protruded stopper portions are formed to permit pivoting movement of the levers to such a degree as to disengage the pawls from the ink cartridge holder.

Abstract: The ink cartridge includes an ink supply port formed at a position, offset to one side, of a wall configuring an ink container body; a positioning projecting portion, formed on one wall out of two opposing walls adjacent the wall, whose upper surface and side portion are regulated in position when the cartridge has been mounted on a recording apparatus; a lever, formed on the other wall out of the two walls, maintaining a normal hinged-open state and having a projection that is forcibly displaced outward when the cartridge is mounted on the recording apparatus; and electrodes that are connected to a memory unit storing information on the ink in an ink container and formed on the positioning projecting portion.

Abstract: When ink is filled into an ink pack 13 including a bag part 20 and an outlet part 21, firstly, air in the bag 20 and outlet part 21 is sucked by a suction pump P2 provided for an ink pouring apparatus 30. Further, by a first measuring pipe 43, ink supplied from a main tank 31 is poured through the outlet part 21 into the bag part 20. Further, by a second measuring pipe 52, the ink poured into the bag part 20 of the ink pack 13 is sucked and exhausted. Furthermore, the ink in the second measuring pipe 52 is mixed into a mixing tank 34 with ink previously supplied to the mixing tank 34 from the main tank 31. Next, the ink is supplied from the mixing tank 34 to a third measuring pipe 59, and filled from the third measuring pipe 59 through the outlet part 21 into the bag part 20.
