Liquid supplying system and liquid supply container

A liquid supply system comprising:

• a negative pressure producing member accommodating chamber accommodating therein a negative pressure producing member and having a liquid supply portion for supplying liquid to outside;
• a liquid supply container connected with said negative pressure producing member accommodating chamber through a connecting portion and having a liquid reservoir portion which defines a substantially sealed space except for the connecting portion;
• an electrode extended parallel with a bottom surface of said liquid supply container, provided at least below said liquid supply container;
• and
• detecting means for detecting an amount of remaining liquid in said liquid containing portion based on an electrostatic capacity between said electrode and liquid in the liquid supply container, wherein another configuration of said liquid reservoir portion is substantially similar to an inner configuration of said liquid supply container, and constructed to provide a negative pressure corresponding to deformation of a part thereof corresponding to the bottom surface of said liquid supply container.

A liquid container comprising:

• a liquid containing portion for accommodating liquid;
• a liquid discharge portion for discharging the liquid to outside;
• wherein said liquid supply container is provided with a bottom surface which is opposed to an electrode disposed below said liquid supply container, said electrode for detecting remaining amount of the liquid in said liquid containing portion based on an electrostatic capacity between said electrode and the liquid;
• wherein the liquid supply container is inclined relative to said electrode.

A liquid supply container comprising:

• a plurality of liquid containing portions for accommodating liquid;
• and
• a plurality of liquid discharge portions for discharging the liquid from respective ones of said plurality of liquid containing portions to outside;
• wherein said liquid containing portions are disposed adjacent to one another;
• wherein said liquid containing portions are each provided with a bottom wall to which an electrode is arranged for detecting a remaining amount of the liquid in said liquid containing portions based on an impedance between the liquid and said electrode;
• and
• wherein said liquid containing portions each include a side wall opposed to the liquid containing portion adjacent thereto, said side walls having a thickness larger than that of said bottom walls.

A liquid container comprising:

• a liquid discharge portion for discharging the liquid to outside;
• wherein said liquid containing portion is provided with a bottom wall to which an electrode is arranged for detecting a remaining amount of the liquid in said liquid containing portion based on an impedance between the liquid and said electrode;
• and
• a separating structure, provided in a region of said liquid containing portion at a liquid supply portion side beyond a portion opposed the electrode, for separating liquid in a region opposed to said electrode from the liquid supply portion side when a remaining amount of liquid in said liquid containing portion is a predetermined amount.
