Abstract
A liquid container for an ink jet apparatus requires only one liquid preserving container for a single kind of liquid even when a plurality of ink jet recording elements are used and which can also be expected to improve the printing density and the printing speed. For this purpose, a plurality of liquid supplying portions are provided in a liquid container having a liquid containing portion containing therein a sponge or the like for holding a single kind of liquid, and a liquid supplying port for supplying the liquid to ink jet recording elements.
Claims28
A liquid container for an ink jet apparatus having a plurality of recording elements each provided with plural discharge ports, said liquid container being removably mountable with respect to the plurality of recording elements, said liquid container comprising:
- a liquid containing portion containing a single kind of liquid therein;
- a plurality of supplying portions provided in a number corresponding to a number of the plurality of recording elements, each for supplying the same liquid from said liquid containing portion out of said liquid container to a corresponding one of said plurality of recording elements, all of which discharge the same liquid;
- and
- an atmosphere communicating portion for communicating an interior of said liquid containing portion with the atmosphere and for enabling supply of the liquid from said plurality of supplying portions to the plurality of recording elements of the ink jet apparatus.
A liquid container for an ink jet apparatus having a plurality of recording elements each provided with plural discharge ports, said liquid container being removably mounted with respect to the plurality of recording elements, said liquid container comprising:
- a liquid containing portion containing a single kind of liquid therein;
- a plurality of supplying portions provided in a number corresponding to a number of the plurality of recording elements, each for supplying the same liquid from said liquid containing portion out of said liquid container to a corresponding one of said plurality of recording elements, all of which discharge the same liquid;
- and
- an atmosphere communicating portion for communicating an interior of said liquid containing portion with the atmosphere and for enabling supply of the liquid from said plurality of supplying portions to the plurality of recording elements of the ink jet apparatus,
- wherein said liquid containing portion comprises first and second chambers, wherein the first chamber is provided with a first plurality of said plurality of supplying portions and is further provided with said atmosphere communicating portion and a liquid holding member, and wherein the second chamber is a substantially closed space except a communication opening provided for communication with said first chamber, the second chamber communicating with said first chamber only through said communication opening and containing therein liquid to be supplied to said first chamber, and
- wherein the number of said first plurality of supplying portions disposed in said first chamber is two, said two supplying portions being juxtaposed so that distances thereof from said communication opening portion are substantially equal to each other.
A liquid container for an ink jet apparatus having a plurality of recording elements, said liquid container being removably mounted with respect to the plurality of recording elements, said liquid container comprising:
- a liquid containing portion containing a single kind of liquid therein;
- a plurality of supplying portions provided in a number corresponding to a number of the plurality of recording elements, projecting outwardly from said liquid containing portion, each supplying portion for supplying the same liquid from said liquid containing portion out of said liquid container to a corresponding one of said plurality of recording elements, all of which discharge the same liquid;
- and
- an atmosphere communicating portion for communicating an interior of said liquid containing portion with the atmosphere and for enabling supply of the liquid from said plurality of supplying portions to the plurality of recording elements of the ink jet apparatus, and for providing a negative pressure source;
- an absorbing member disposed in said liquid containing portion;
- and
- a fibrous material in contact with said absorbing member and arranged in each of said plurality of supplying portions at least in a vicinity of outward projections thereof,
- wherein said liquid containing portion comprises first and second chambers, wherein the first chamber is provided with a first plurality of said plurality of supplying portions and is further provided with said atmosphere communicating portion and said absorbing member, and wherein the second chamber is a substantially closed space except a communication opening provided for communication with said first chamber, the second chamber communicating with said first chamber only through said communication opening and containing therein liquid to be supplied to said first chamber, and
- wherein the number of said first plurality of supplying portions disposed in said first chamber is two, said two supplying portions being juxtaposed so that distances thereof from said communication opening portion are substantially equal to each other.
