<P>PROBLEM TO BE SOLVED: To provide a liquid cartridge which does not uselessly eject the indispensable liquid to be inhaled in restoration operation of an ejection head. <P>SOLUTION: The liquid cartridge has a liquid ejection portion 1 for ejecting liquid droplets, a reservoir E1 for storing liquid, and a communicating member 3 for providing communication between both of them. The reservoir E1 has first and second storage portions 10a, 10b isolated by films 6 to 8 arranged spaced from each other and an atmospheric release portion. When a small diameter portion 5a is inserted into an applied concave portion 4 of the liquid ejection portion 1, a tip 3a of the communicating member 3 breaks through the first to third films 6 to 8 sequentially in the period from the beginning to the end of insertion. Consequently, the ejection head 2 is filled with liquid in the first storage portion 10a and thereafter is filled with liquid stored in the second storage portion 10b. <P>COPYRIGHT: (C)2009,JPO&INPIT |
