Abstract
An ink package has a shape restoring ability and is made of a laminated structure film material in which multiple film sheets of polyethylene or similar material are laminated. Therefore, the ink supplying pressure for ink supplied to the print head is kept at a negative pressure. Since the ink extracting member is formed into a needle-like hollow body, the member can be easily stuck into a recess formed at the ink package.
