摘要： A liquid container comprises an inner wall that forms the liquid containing portion to contain liquid therein; an outer wall that forms the container to contain the liquid containing portion therein; and a liquid supply portion for supplying liquid from the liquid containing portion to the outside. Then, the inner wall is arranged to be a member to generate negative pressure in the liquid containing portion by being deformed following the leading-out of the liquid, and also, formed by the material having an elastic modulus change of 25% or less against the temperature change of use environment. With the liquid container thus structured, it is possible to implement the stable supply of liquid by stabilizing the characteristic of negative pressure in the liquid containing portion thereof irrespective of the temperature changes of use environments.

摘要： An ink supply system which includes an ink jet head for discharging ink and an ink tank retaining ink to be supplied to the ink jet head through a passage. A negative pressure generating container is provided along the passage, and generates negative pressure by a restoring force at the time of being deformed. With the ink supply system thus structured, it becomes possible to perform stable recording, because the fluctuation of flow resistance due to the fluctuation of discharge amount is made smaller, and also, there is almost no fluctuation of pressure along the carriage operation. Also, the retaining amount of ink becomes suitably greater for the performance of higher speed printing, and the replacement of ink tanks is possible, while ink still remains in the negative pressure generating container, hence making it possible to essentially prevent a complete ink depletion.
