Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
126 words
An ink jet printing device for recording medium comprising a printing head adapted to move back and forth along said recording medium and provided with a plurality of output nozzles through which ink droplets are propelled onto the recording medium to selectively form indicia thereon, a pumping chamber for each nozzle being in communication therewith, an ink reservoir, at least one channel connecting said ink reservoir with said pumping chambers, means mounting said ink reservoir for movement which follows the movement of said printing head, said reservoir continuously feeding the pump chambers with ink through said channel, and a fixed liquid supply device arranged to co-act with said reservoir in one or both end positions of said printing head in order to automatically refill said reservoir.
Claim 2
Dependent Claim
126 words
An ink jet printing device for recording medium comprising a printing head adapted to move back and forth along said recording medium and provided with a plurality of output nozzles through which ink droplets are propelled onto the recording medium to selectively form indicia thereon, a pumping chamber for each nozzle being in communication therewith, an ink reservoir, at least one channel connecting said ink reservoir with said pumping chambers, means mounting said ink reservoir for movement which follows the movement of said printing head, said reservoir continuously feeding the pump chambers with ink through said channel, and a fixed liquid supply device arranged to co-act with said reservoir in one or both end positions of said printing head in order to automatically refill said reservoir.
Claim 3
Dependent Claim
17 words
The combination as claimed in claim 1 further comprising a liquid absorbing material in said ink reservoir.
Claim 4
Dependent Claim
16 words
The combination as claimed in claim 2 wherein said liquid absorbing material fills said ink reservoir.
Claim 5
Dependent Claim
31 words
The combination as claimed in claim 2 wherein said liquid supply device comprises a wick that communicates with the liquid stored therein and co-acts with an opening in the ink reservoir.
Claim 6
Dependent Claim

The combination as claimed in claim 6 wherein the end of said wick projects from said liquid supply device and is adapted to be inserted in said opening to deliver liquid to said reservoir.
Claim 9
Dependent Claim
38 words
The combination as claimed in claim 6 wherein said liquid supply device comprises a receptacle and a flexible disposable container therein, the latter being provided with the printing liquid for the printing head of said ink jet printer.
Claim 10
Dependent Claim
23 words
The combination as claimed in claim 8 further comprising a wick having one end projecting through a side wall of said disposable container.
Claim 11
Dependent Claim
33 words
The combination as claimed in claim 9 wherein said receptacle is provided with an opening through which the end of said wick protrudes, said receptacle functioning as a holder for said disposable container.
