Description

Ink supply method reaches to realizing the used ink supply device of this method

The present invention relates to the print cartridge used to ink-jet printer etc. supply with ink ink supply method and can the best ink supply device that uses for implementing this method.

In recent years, ink-jet printer obtains extensively to popularize. and in this ink-jet printer, the print cartridge that freely loads and unloads of filling ink is installed, supplies with ink to printhead by this print cartridge.

Present present situation is that print cartridge is using the ink of being filled basically, is about to it and abandons.

Yet the price of print cartridge is quite high, concerning the user; the like this print cartridge of high price of conversion continually; be one one kinds of huge financial burden. also have, this has become in recent years the saving resource and the dangerous act of protection environment, so the user also holds dislike to it.

Particularly, full color with print cartridge for cyan (c), fuchsin (M), ink of yellow (Y) three looks or nearest multi-color ink more than three looks is separated in a print cartridge accommodate, because each colored ink amount of accommodating is few, in any case and consumption figure of all kinds also can change, therefore, although the few ink of consumption figure has been left, also also have situation about needing more also, thereby more strengthened above-mentioned sensation.

Also have, though print cartridge is just accommodated the ink of having accommodated, box body itself can re-use toward contact.

Therefore, just the someone proposes: with the problem that providing ink has used the print cartridge that is over to re-use, the ink supply device 9 that for example illustrates on Figure 15 etc. are exactly one one kinds of commercially available prod.

Such ink supply device 9 is to be arranged on the top of print cartridge 8 at the injection aciculiform injection part of being installed by the bottom of the military retractile plastic ink tank 9l of snake abdomen 92, and when insert making under the state of filling ink with hole 80 (sticking sealings such as film usually) etc., press among the figure shown in the white arrow, press...with one's finger and press ink tank 91 and in print cartridge 8, inject ink.

For when printing the limit regulate by print cartridge and supply with the amount of ink to printhead, perhaps the ink that suppresses in the print cartridge of limit moves freely (fluctuation etc.) or ink leak water, shown in two chain-dotted lines among the figure, the print cartridge of the felt 8a type that impregnated with ink is housed in print cartridge 8 is arranged.

In such print cartridge 8, if when using the ink supply device 9 of described figure to supply with ink, especially, when felt 8a is high compression, then ink supplied is owing to the air that is subjected in the felt 8a is hindered, and fully do not soak in this felt 8a and overflowed, the anxiety that can not supply with the quantity sufficient ink is just arranged.

Also have, because below felt 8a, air is left near the zone of ink outlet 8l that is print cartridge 8, therefore become the state that ink can not directly come out from above-mentioned outlet 8l, again print cartridge 8 is put into ink-jet printer, restart the initial stage of its use at it, owing to the unfavorable condition that produces ink cartridge low etc. has the anxiety that can not correctly print.

Also have, because below felt 8a, promptly near the ink outlet 81 of print cartridge 8, leave air, so just become the state that can not directly provide ink by above-mentioned outlet 81, again print cartridge 8 is installed to ink-jet printer, when restarting its use again, because bad phenomenon such as generation ink cartridge low also have the anxiety that produces bad printing.

Also have, the bad phenomenon of ink cartridge low can be by twice or thrice solving the cleaning of printhead repeatedly, but, cleaning mainly is to be undertaken by a large amount of ink that spues, therefore just produce and more increase wash number, then the consumption of printhead and ink is stronger, the problem that the life-span of printhead is shorter than common printhead.

The objective of the invention is to, provide a kind of print cartridge that the felt type is housed to supply with the new ink supply method of ink well, and for implementing the best novel ink feeder that uses of this method.

Ink supply method of the present invention is characterized in that making under the state that reduces pressure in the print cartridge by the decompression device, supplies with ink by filling the ink tank of supplying with ink.

According to this kind ink supply method of the present invention, for example, even the felt of high compression is housed in print cartridge, reduce pressure by the decompression device, remove the most of air in print cartridge that contains at this felt, under this kind state, supply with ink, therefore can make the ink of quantity sufficient promptly be impregnated into respectively all dividing in the felt from ink tank.

Therefore,, can supply with the ink of quantity sufficient well, so that restarting to use the print cartridge initial stage, the situation such as bad of ink cartridge low does not take place yet according to the present invention.

Secondly, for implementing the ink supply device of the above-mentioned ink supply method of the present invention, it is characterized in that the piston that has cylinder and freely plug at this cylinder, has the ink tank function that under the state that specified rate supply ink is filled, is connected and supplies with ink to this print cartridge with print cartridge, but also have under above-mentioned state by attract the air in the print cartridge by the cylinder jigger lifting piston, and be housed in the ink level upper area of isolating by space in ink in the cylinder and the print cartridge, make the function of the decompression device of decompression in the print cartridge.

This ink supply device of the present invention has ink tank and decompression device as mentioned above concurrently, and is therefore simple in structure, operation easily, and can implement ink supply method of the present invention best.

Implement best mode of the present invention

(b) example of key diagram 1 and Fig. 2 (a) at first.

As shown in these figures, this routine ink supply device 1 is made with syringe shape, is made by synthetic resin, and it includes cylinder 2 and the piston 3 that freely plugs at this cylinder 2.

That is to say that cylinder 2 integral body form with cylindrical shape, simultaneously, its other end can load and unload the injection part 4 that freely connects as have the ascending pipe 42 of metal control, compares with main part to be path.And be provided with providing ink hole 2a at this minor diameter part.

Also have, piston 3 has the sealing of limit maintenance and cylinder 2 at its front end, the limit can make the seal 3a that is made by flexible materials such as rubber that slides in this cylinder 2, and at its flange part 3b that becomes handle when the other end then has cylinder 2 these pistons 3 of plug operation longitudinally, slightly is cylindricality

Front end at piston 3 is provided with by the sealing of limit maintenance with cylinder 2, the seal 3a that the limit can make flexible materials such as rubber of slip in this cylinder 2 make.

Also have, the injection part 4 that is connected with the minor diameter part of the front end of cylinder 2 has the ascending pipe of being made up of foregoing metal tube etc. 42, and the while is provided with the seal 43 that is formed by flexible materials such as rubber at the middle part of this ascending pipe 42.

So, by such seal 43 is pressed into print cartridge 8 that be provided with above, when making filling ink with hole 80, make the sky of cylinder 2 hear with print cartridge 8 in by the through holes (not shown) of supply hole 2a with ascending pipe 42, the sealing strip connection the when limit keeps decompression.

Under the situation of illustrated example, ascending pipe 42 forms with near insert the felt 8a in the print cartridge 8 and reach print cartridge 8 bottoms length. like this, if it is the length of ascending pipe 42 is long, then can better ink supplied be supplied to the bottom of print cartridge 8, can be further prevent from when foregoing initial stage of restarting to use print cartridge 8, to take place unfavorable condition such as ink cartridge low on the spot.

But the length of ascending pipe 42 can be set suitable length according to the structure of print cartridge 8 or ink supply method etc.

Be not particularly limited at the capacity of ink from feeder 1 intermediate roll 2. still, have the supply ink I that can accommodate specified rate and by by cylinder 2 jigger lifting pistons 3 by the capacity of 1-20 times air of the above-mentioned ink I volumes that attract in the print cartridge 8, be desirable.

At the capacity of cylinder 2 is that above-mentioned scope is when following, promptly accommodating the supply ink I of specified rate only, under the situation of the capacity of the air below a times of the volume of this ink I, owing to can not make decompression in the print cartridge 8 fully, otherwise can not in the print cartridge of the felt 8a type that high compression is housed, supply with ink well so just have., when the capacity of cylinder 2 surpasses above-mentioned scope, promptly can accommodate the supply ink I of specified rate, under the situation of the air containment of 20 times of the volumes that surpasses this ink I, the size of ink supply device 1 becomes excessive, just has keeping or carrying etc. mostly to be the anxiety of inconvenience.

Problem such as size, shape as for other is not particularly limited, but for example under the situation of the cylinder 2 of same capability, it is big that its diameter more becomes, its length more shortens, and when attracting air by cylinder 2 jigger lifting pistons 3, needs very big power, otherwise, its diameter is littler, and the power when then attracting air more reduces, and the length of cylinder 2 is more elongated.Therefore, can consider that these factors set size, shape.

When using above-mentioned ink supply device 1 in the print cartridge 8 that high compression felt 8a is housed as shown in the figure, to supply with ink, at first block ink outlet 81 with encapsulant etc., simultaneously foregoing be arranged on hole 80 print cartridge 8 above, that filling ink is used during manufacturing for the film shown in the figure that blocks this hole and stick on perforate, perhaps, expose film by only throwing off the part in above-mentioned hole 80.

Also have, the main body of print cartridge 8 is made into two parts up and down usually, portion installs after the felt 8a within it, through welding forming, yet under the incomplete situation of welding, if by its surperficial 82 invading airs, then have and can not make in the print cartridge 8 the fully anxieties of decompressions. therefore, for example, absorb with water gaging feeder 1 and to lack etc., if by surperficial 82 invading airs, then available sealant tape is blocked this surface 82.

Secondly, prepare one has supplied with specified rate ink I and has been filled into ink supply device 1 in the cylinder 2.

Also the ink I of specified rate can be pre-charged with in the cylinder 2. still, when under untapped state, existing for ink supply device 1, aging for the seal 3a that prevents ink leak water or piston 3 front ends, when using each time, can specified rate ink I be filled in the cylinder 2 by the ink tank of specially preparing (not shown), be desirable.

For the ink I with specified rate is filled in the cylinder 2, will be by the main points of syringe, the front end of ascending pipe 42 that also can earlier piston 3 be pressed into the lowermost ink supply device 1 of cylinder 2 is impregnated in the ink tank under the ink level, and jigger lifting piston 3 then, and ink is sucked in the cylinder 2.

Also have, when filling ink, note not making as much as possible air to enter in the cylinder 2, if have an air to enter a little, then can not produce such problem, still, as long as there is air to enter, then in next technology, pass through by cylinder 2 jigger lifting pistons 3, reduce from the print cartridge 8 interior air capacities that can attract, thereby cause decompression degree step-down.

Also have, for any can accomplishing per capita all can be filled in the cylinder 2 being substantially an a certain amount of ink I, the position of jigger lifting piston 3 is the graticule of target when being provided with the suction ink in the outside of cylinder 2, is desirable.

Secondly, as mentioned above, with above-mentioned ink supply device 1 by being pressed into to the hole 80 of seal 43, sealing when the limit keeps decompression, the limit is connected with print cartridge 8, then, and under the state that ink supply device 1 is being stood with approximate vertical, go up shown in the white arrow according to Fig. 1 and Fig. 2 (a), piston 3 is pulled to the top by cylinder 2.

Like this, air in the print cartridge 8 are attracted, and by ascending pipe 42, and then make and produce bubble B in the ink I and rise, and be housed in by the ink I liquid level upper area [Fig. 2 (b)] of the ink I in the cylinder 2 and the space isolation of print cartridge 8 so., be decompression state in the print cartridge 8.

Also have, for any attraction a certain amount of air substantially of can accomplishing per capita, identical with the situation of above-mentioned ink, the position of jigger lifting piston 3 is the graticule of target when the setting of the outside of cylinder 2 attracts with air, is desirable.

Secondly, when this kind state is set about from piston 3 departure motions, owing to become in the print cartridge 8 of decompression state pressure differential with atmosphere, as Fig. 2 [b) shown in the black arrow, piston 3 is pressed into the below, the air A that accommodated by this ink I liquid level upper area of ink I in the cylinder 2 is extruded thereupon, and supplies with in the print cartridge 8 of decompression states by ascending pipe 42.

At this moment in order to help the injection of ink, also available hand is pressed to the below with piston 3.

Also have, be raised piston 3 extracts out from cylinder 2 fully even will attract air, because the effect of external and internal pressure difference, same as described above, also ink I can be supplied with in the print cartridge 8. in this case, there is not frictional resistance when descending, so might more successfully supply with ink I. still owing to piston 3, should be noted that: the vibration during owing to extraction piston 3 has the ink I in the cylinder 2 to fly shallow anxiety.

Therefore, can consider that also piston 3 is provided with the hole of exhaust on the position that cylinder 2 promotes to a certain degree, do not extract piston 3 and can obtain result same as described above yet.

Ink supplied I, especially is impregnated near the ink I outlet 81 of print cartridge 8 so even the felt 8a of high compression is not hindered by air, the ink of its quantity sufficient can promptly be impregnated into its inner various piece owing to become decompression state in the print cartridge 8.

After having supplied with specified rate ink I, take off ink supply device 1 by print cartridge 8, also the encapsulant (not shown) of making other purposes and preparing can be attached to print cartridge 8 above, block hole 80.

As mentioned above, 3 in the piston that will be pre-charged with the ink supply device 1 of specified rate ink I according to legend is perhaps only depressed after promoting by the specified rate lifting, just may well ink I be supplied with in this print cartridge 8.

Therefore, by use supplying with the print cartridge 8 of ink I, unfavorable conditions such as ink cartridge low can not take place from the initial period of restarting its use, and can carry out good printing.

Secondly, key diagram 3 one Fig. 5 (a) are example (b).

As shown in Figure 3, this routine ink supply device l makes with syringe shape, and it is to be formed by synthetic resin etc., and comprises cylinder 2 and the piston 3 that freely plugs on this cylinder 2.

That is to say, cylinder 2, it is whole, and its front end can load and unload and freely be connected with injection part 4 simultaneously in order to be cylindrical shape formation, and its footpath is littler than main part, and this minor diameter part is provided with providing ink hole 2a.

Also have, piston 3 is equipped with at its front end and keeps with the sealing of cylinder 2 and can make seal 3a slip this cylinder 2 in, that made by flexible materials such as rubber, and, slightly be cylindricality at its flange part 3b that becomes handle when another end is equipped with cylinder 2 these pistons 3 of plug operation longitudinally.

Also have, the injection part 4 that is connected with the minor diameter part of the front end of cylinder 2 is equipped with ascending pipe 42, still as previously mentioned, this ascending pipe is made of institutes such as metal tubes, be inserted into the felt 8a in the print cartridge 8, have near the length that can reach print cartridge 8 bottoms, be equipped with by the formed seal 43 of flexible materials such as rubber at the middle part of this ascending pipe 42 simultaneously.

Then, as shown in Figure 4, by the through holes (not shown) of supply hole 2a with ascending pipe 42, the limit keeps the sealing strip connection of reducing pressure in the hole 80 that filling ink is used when such seal 43 being pressed into the manufacturing that print cartridge 8 is provided with above, the space in the cylinder 2 and print cartridge 8.

In such cases, the length of ascending pipe 42 also can be set suitable length according to the structure of print cartridge 8 or ink supply method etc.

So far, the example with former is identical.

This example is with former example difference, form on the piston 3 in above-mentioned by the front end face of seal 3a rear end face to flange part 3b, there is its footpath direction central part to connect, like this, is formed with connection ink level upper area and the outside passage 3c that is connected in the space in cylinder 2.

So, above-mentioned passage 3c constitutes in the following manner, promptly, as previously mentioned, switch is carried out in the outside by at the key c1 of its flange part 3b side opening loading and unloading as switch block. that is to say, as shown in Figure 4, spigot c1 is pressed into the opening of the side of flange part 3b side, then blocks passage 3c, as shown in Figure 3, if take off from above-mentioned opening, then passage 3c is open.

Such spigot c1 is when being pressed into above-mentioned opening, and in order to block passage 3c on the spot, then the integral body of this spigot is made with soft synthetic resins such as polyethylene or rubber etc.

Also have, on spigot c1, go out spigot cla can be set, shown in a chain-dotted line among Fig. 3, when this spigot is taken out this spigot c1 by the opening of passage 3c and do not lose, and bolt obtains protecting on piston 3 and earns such spigot cla and can use and key Cl identical materials monolithic molding.

In order to utilize this routine ink supply device l with above-mentioned each parts, supply with ink to the print cartridge that high compression felt 8a is housed shown in Figure 48, at first same as described above, block the outlet 81 of ink with encapsulant, the hole 80 that filling ink is used during the manufacturing that is provided with on print cartridge 8 simultaneously is perforate on the not shown film of blocking this hole and sticking, perhaps film is exposed by the part of only throwing off above-mentioned hole 80. also have, when the welding on the surface 82 of print cartridge 8 is incomplete, block this surface 82 with sealant tape etc.

Secondly, prepare an ink supply device 1 in the cylinder 2 of the ink I of specified rate having been filled.

Also the ink I of specified rate can be pre-charged with in the cylinder 2. when using each time, also can be according to the main points of syringe, the ink I with specified rate sucks or is filled in the cylinder 2 by ready ink tank (not shown) specially.

Also have, when filling ink, need be pressed into spigot cl certainly and block passage 3c. in addition,, do not allow air enter in the cylinder 2 possibly although will note in order to prevent the decompression degree step-down in next technology.

For any can accomplishing per capita is filled into cylinder 2 with an a certain amount of ink substantially, same as described above, be provided with in the outside of cylinder 2 that the position of jigger lifting piston 3 is the graticule of target when absorbing ink, be desirable.

Secondly, as mentioned above, by the hole 80 of above-mentioned ink supply device 1 to seal 43 is pressed into, sealing in the time of can keeping reducing pressure also is connected with print cartridge 8, then, under the state that ink supply device 1 is being stood with approximate vertical, press Fig. 4 and Fig. 5 (a) and go up shown in the white arrow, piston 3 is promoted upward by cylinder 2.

Like this, air in the print cartridge 8 are attracted, and by ascending pipe 42, and then make and produce bubble B in the ink I and rise, and be housed in by the liquid level upper area [Fig. 5 (b)] of the ink I of the space isolation in ink I in the cylinder 2 and the print cartridge 8 so., be decompression state in the print cartridge 8.

Also having, can accomplish to attract substantially air in certain amount per capita for any, so the position of jigger lifting piston 3 is the graticule of target when still being provided with absorption of air in the outside of cylinder 2 in such cases, is desirable.

So far technology is to carry out being pressed under the state that key c1 blocks passage 3c

Secondly, shown in Fig. 5 (b), if take off the open passage 3c of spigot c1, then shown in the arrow of double dot dash line among this figure, flow into air by passage 3c by outside ink I liquid level upper area in cylinder 2, become atmospheric pressure thereby make in this zone, owing to the print cartridge 8 that becomes decompression state in pressure differential make the ink I in the cylinder 2 press to the below, and supply with in the print cartridge 8 of decompression states by ascending pipe 42.

And this moment, if take off the piston 3 of lifting fully, then will more promptly carry out the supply of ink I by cylinder 2.

Owing to become decompression state in the print cartridge 8,, especially be impregnated near the ink I outlet 81 of print cartridge 8 so even the felt 8a of high compression is not hindered by air yet, the ink I that supplies with quantity sufficient can promptly be impregnated into its inner various piece.

After having supplied with specified rate ink I, take off ink supply device 1 by print cartridge 8, also the encapsulant (not shown) of making other purposes and preparing can be attached to China ink close 8 above, block hole 80.

As mentioned above, after the piston 3 that is pre-charged with specified rate ink worker's ink supply device 1 according to legend promotes by specified rate, take off key c1 and only open passage 3c, perhaps take off after the key c1, only withdraw from piston 3 again, all can well ink I be supplied with print cartridge 8.

Therefore, by using the print cartridge 8 supplied with ink I, unfavorable conditions such as ink cartridge low can not take place from the initial period of restarting its use, can carry out good printing.

Also have, do not open passage 3c and directly block, promptly under the state identical, use the hand piston, perhaps make it to advance automatically, all within the ink I supply print cartridge 8 that can cylinder 2 is interior owing to inside and outside pressure differential with preceding Fig. 1 example by key c1.

Also have, for example the people a little less than strength such as woman, have lifting directly to block the piston 3 of passage 3c by key c1, making becomes the very difficult situation of decompression state in the print cartridge 8. also have, under the situation of the felt 8a that does not accommodate high compression, never need print cartridge 8 is made decompression state.

Therefore, in these cases, as shown in Figure 4, under the ink supply device l that will fill specified rate ink I and state that print cartridge 8 is connected, if directly taking off key c1 opens passage 3c, then ink I falls naturally, supplies with print cartridge 8.

Also have, in this case, the seal 43 with injection part 4 is not pressed into the hole 80 of print cartridge 8 and makes space etc., prevents that the interior pressure of print cartridge 8 uprises along with the supply of ink I, can more successfully supply with ink yet.

As mentioned above, according to this routine ink supply device 1, how variety classes can adopt the whole bag of tricks the ink of quantity sufficient can be supplied with print cartridge 8 well, and in the initial stage of bringing into use again bad phenomenon such as ink cartridge low does not take place.

Also have, passage is not arranged on the piston, can be arranged on the cylinder yet. and, also can passage be set two sides of piston and cylinder.

Switch block is not limited to spigot, also can adopt valve etc.

Below, key diagram 6--Fig. 8 (a) is example (b).

As shown in Figure 6, this routine ink supply device 1 is also made with syringe shape, the plug 3 that it comprises cylinder 2, freely plugs at this cylinder 2, and the injection part 4 used of the injection ink that is connected with the front end of described cylinder 2.

Its intermediate roll 2 is entirely by global formations such as synthetic resin, it has the cylindrical body portion 2l that an end makes the opening 21a that is used to plug piston 3, block the bowl-type end plate 22 of another end of this main part 21, and be provided with by the central part of this end plate 22 below in figure is outstanding, connect injection part 4 and have the locking part 23a in big slightly footpath for freely loading and unloading with coaxial path tubular connecting portion 23. these connecting portions 23 of main part 21, this locking part should be prevented lifting when connecting injection part 4, though be difficult to judge from figure, middle part outside it and the inner peripheral surface of the described flange part 41a in back lock together and prevent injection part 4 to break away from.

The whole of piston 3 also are integrally formed by synthetic resin etc. it has: an end is made to the opening 31a of ink chamber and the other end is plugged, its inside makes ink chamber 30 cylindrical-shaped main body 31; Two

groove

31b, 31b that form in the periphery of the opening 31a of this main part 31 side one end sealing ring sr, sr chimeric respectively, that the limit keeps and the sealing strip of cylinder 2 makes these cylinder 2 slips and made by flexible materials such as rubber and soft resins; Aforementioned body 31 by the other end of blocking to outstanding be provided with, the flange part 32 that becomes handle when cylinder 2 plugged operated piston 3 of direction foreign side radially.

In the case of this example, hydroecium 30 formation of above-mentioned China and Mexico can be filled the above volume of supplying with ink twice.

Injection part 4 is to be made by synthetic resin etc., it has the connecting portion 4l that can be connected with the connecting portion 23 of cylinder 2, the ascending pipe 42 of the metal control of installing at the front end of this connecting portion 41, and the seal of making by flexible materials such as rubber or soft resins 43 that keeps sealing at (with reference to the Fig. 7) in the hole 80 that be provided with, that be pressed into print cartridge 8, middle part of this ascending pipe 42, for the time in decompression.

Also have, end at above-mentioned connecting portion 41 is provided with flange part 41a, as previously mentioned, and when this flange part connects at the connecting portion 23 of cylinder 2, this inner peripheral surface and locking part 23a are sealed and have and prevent the function that breaks away from, simultaneously when removing above-mentioned connection and have a handle function.

In this case, ascending pipe 42, the formation of its length remains and can reach the felt 8b that inserts in the print cartridge 8, is inserted near the bottom of print cartridge 8, but can sets suitable length according to the structure of print cartridge 8 or ink supply method etc.

In order to utilize this routine ink supply device 1 with above-mentioned each parts, in the print cartridge 8 of as shown in Figure 7 the felt 8a that high compression is housed, supply with ink, at first same as described above, block ink outlet 8l with encapsulant, filling ink is perforate on the not shown film of blocking this mouthful and pasting with hole 80 during the manufacturing that is provided with on print cartridge 8 simultaneously, perhaps film is exposed by the part of only throwing off above-mentioned hole 80. also have, when surface 82 welding is incomplete, block this surface 82 with sealant tape etc.

Secondly, prepare a kind of like this ink supply device l, as shown in the figure,, be filled in the ink chamber 30 of piston 3 with the supply ink I of specified rate (being more than twice as previously mentioned) in advance at the stop position that piston 3 is pressed into cylinder 2.

So, as mentioned above, by the hole 80 of this ink supply device 1 to seal 43 is pressed into, sealing in the time of can keeping reducing pressure also is connected with print cartridge 8, then, under the state that ink supply device l is being stood with approximate vertical, press shown in Fig. 7 and Fig. 8 (a) white arrow, piston 3 is promoted upward by cylinder 2.

Like this, air in the print cartridge 8 is attracted, hand-hole 42 by injection part 4, and then make and produce bubble B in the ink I and rise, and be housed in by the ink worker's of the space isolation in ink I in the ink chamber 30 and the print cartridge 8 liquid level upper area [Fig. 8 (b)] so. be decompression state in the print cartridge 8.

Ink supplied I is owing to become decompression state in the print cartridge 8, even the felt 8a of high compression and not hindered by air, can promptly be impregnated into its inner various piece so supply with the ink I of quantity sufficient, especially be impregnated near the outlet 81 of ink I of print cartridge 8.

After the ink I of specified rate supplies with, also the off-the-shelf encapsulant (not shown) of other purposes can be attached on the print cartridge 8, block hole 80.

Also have, as mentioned above, if ink supply device l supplies with specified rate ink I, then piston 3 returns to the A-stage that is pressed into stop position on cylinder 2, therefore at this moment in ink chamber 30, leave under the situation of the later ink supplied I of secondary, also can add bolt, perhaps take injection part 4 at the front end of ascending pipe, connecting portion 23 at cylinder 2 directly adds bolt, is saved in providing ink next time.

In addition, also have when being pressed into piston 3 automatically by atm difference, and before returning to above-mentioned A-stage, the situation that piston 3 stops.Its reason can think that preliminary vacuum is insufficient, and pair anxiety of ink I quantity delivered deficiency is arranged this moment, till therefore also available hand begins to be depressed into A-stage with piston 3 from stop position.

As mentioned above, in legend, need only the piston 3 that promotes or after promoting, press again the ink supply device 1 that is pre-charged with specified rate ink worker by specified rate, just can be well with in the providing ink print cartridge 8.

Therefore, utilize the print cartridge 8 supplied with ink, just can be from beginning that again unfavorable conditions such as ink cartridge low are not taken place the initial stage of its use, and can carry out good printing.

And, in this example, as previously mentioned, piston 3 is being filled under the state of cylinder 2 stop positions, owing in the ink chamber 30 of this piston 3, accommodate specified rate ink supplied I, even so in keeping, when packing and transportation etc. are handled to piston 3 reinforcings, the also anxiety that spills of the ink of unmatchful packing, and be easy to handle. therefore, can be with the state that is pre-charged with specified rate ink I to market supply, thus the workload of supplying with ink can be reduced, also can reduce user's burden.

In addition, ink chamber 30 also can form the capacity of only filling one inks. and in such cases, to supply with ink each time, must buy feeder. ink supply device is compared with legend, and the further advantage of miniaturization is arranged.

Also have, on piston 3, be provided with and make ink chamber 30 and the outside passage that is connected, the while also available spigot etc. as this passage of free switch.

In such cases, its advantage is, under the state with spigot closed vent hole, after carrying out reducing pressure in the print cartridge 8, remove spigot and open passage, piston 3 is descended, that is to say the resistance of friction when not producing piston 3 descends, can more successfully ink I be supplied with print cartridge 8.

But, if in ink chamber 30, leave for the second time later ink I, if after supplying with end, then under the state of directly opening passage, need press lower piston 3 with hand, therefore adopt such formation, preferably use foregoing small-sized ink supply device that once is filled into ink chamber 30 with ink.

Ink chamber also can be arranged on the cylinder 2. and for example, the brake of piston 3 is set at the middle part of cylinder 2, also the brake forward part of cylinder 2 can be dressed up ink chamber.Perhaps the outside of cylinder 2 install with cylinder 2 in the ink chamber that is connected. still, in order to make whole feeder 1 miniaturization, shown in legend, it is desirable that ink chamber 30 is set on piston 3.

Shown in legend; when piston 3 is provided with ink chamber 30; cylinder 2 is at least owing to decompression has the volume of jigger lifting piston 3 just passable in the print cartridge 8 in order to make; therefore compare with existing feeder; so also can make whole feeder 1 miniaturization., make whole feeder 1 not too big typeization, for example twice above supply ink I can be filled in the ink chamber 30; can more advance one by one the step alleviates user's burden, also can make contributions to saving resource and protection environment etc. simultaneously.
