Herein, with reference to Fig. 5, transmission mechanism is described.

As shown in Figure 5, in connecting portion 43, the film 61 of liquid chamber 53 forms and can be pushed by spring 62 via compression plate 63 so that the structure that the volume of liquid chamber 53 increases.Therefore,, along with the increase of the volume of liquid chamber 53, the ink in liquid container 33 is by inflow entrance 65 influent chambers 53.On the other hand, attracted to and supply with pin 44 from flow export 52 by supply unit 32 inks, the ink in liquid chamber 53 flows out from liquid chamber 53 via flowing out stream 55 thus.Now, in the present embodiment, be set as greatlyr than the internal diameter of inflow entrance 65 by flowing out the internal diameter of stream 55, the quantity of ink therefore flowing out from liquid chamber 53 is unable to catch up with the quantity of ink of influent chamber 53, thereby in the interior formation negative pressure of liquid chamber 53.So the elastic force that film 61 resists spring 62 deforms with the state being inhaled in liquid chamber 53.What by the way, Fig. 5 represented is that film 61 is inhaled into the state in liquid chamber 53.

The negative pressure that liquid chamber 53 produces, along with the ink in liquid container 33 is slowly eliminated via inflow entrance 65 influent chambers 53.Then, due to the elastic force of spring 62, film 61 is extruded again to the outside of liquid chamber 53, and the volume of liquid chamber 53 restores thus.Therefore, in supply unit 32, supply with ink to fluid jetting head 24 from stopping, after the regular hour, return to again and start to supply with the original state before ink to fluid jetting head 24.In addition, if again supply with ink to fluid jetting head 24 sides from supply unit 32, liquid chamber 53 is interior can form negative pressure, and formation film 61 is inhaled into the state of the inner side of liquid chamber 53.And if ink in liquid container 33 is depleted, even if be negative pressure in liquid chamber 53, ink can influent chamber 53 yet in.That is, from supply unit 32 stops supplying with ink, after the regular hour, the negative pressure in liquid chamber 53 also can not be eliminated, and film 61 maintains the state of the inner side that is inhaled into liquid chamber 53.

On surplus test bar 45, force application spring is installed, so that surplus test bar 45 is crimped on (not shown) on mobile member 64.In addition in surplus test bar 45, with another end 45b of the 45a opposition side, end contacting with mobile member 64, be the detected object position of spill sensor 68.The light-sensitive device that sensor 68 is transmission-type, not shown light accepting part and illuminating part arrange in opposite directions.Carry out the nil case that has of tracer liquid host body 33 interior inks by the detection signal of being exported by this sensor 68.

That is, if there is no ink in liquid container 33, ink can be in the interior influent of liquid container 33 chamber 53, and therefore film 61 maintains to the state being out of shape in the direction that liquid chamber 53 volumes are reduced.Therefore, by not shown spring energized surplus test bar 45, one end 45a extruding mobile member 64 of surplus test bar 45, mobile member 64 is rotated centered by rotating fulcrum, and surplus test bar 45 is to liquid container 33 side shiftings, thereby another end 45b of surplus test bar 45 is inserted between the illuminating part and light accepting part of sensor 68.Therefore, sensor 68 is maintained at blocked state constitutes based on light, carrys out the situation that exhausts of the ink in tracer liquid host body 33.

Next get back to Fig. 2 and Fig. 3, slide block 34 is described.

As shown in Figure 3, in liquid container 33, on the 1st position being positioned at outside printer 11, on the upper surface 39 of liquid container 33, be provided with the inlet (injection oral area) 73 to liquid container 33 interior infusing inks.In the present embodiment, the 1st accommodates body 37 is equivalent to the 1st position, and inlet 73 is arranged on the 1st and accommodates on body 37.And, exposing in order not make to be positioned in inlet 73 outside printer 11 time outside infusing ink, this inlet is designed to the structure that can be hidden by slide block 34.

That is, slide block 34 is for having the essentially rectangular shape of length direction, forms and roughly overlapping outer shape of the upper surface 39 of liquid container 33.And, thereby the upper surface 39 that makes itself and liquid container 33 in one end of slide block 34 is inserted into installation portion 31 is roughly under overlapping installment state, slide block 34 covers the top of the ink inlet 73 that is arranged at liquid container 33 by opening and closing open-close lid 74 freely.Particularly, slide block 34 has open-close lid 74 in the end of its length direction, and this open-close lid 74 can be shifted covering the position of inlet 73 and open between the position of inlet 73.Should illustrate, in the following description, " direction of insertion " unless otherwise prescribed, expression be " direction of insertion " of slide block 34 with respect to installation portion 31.

Further, on the bottom surface 152a of the 2nd ink chamber 152, on left and right directions X, on two positions of the front side corresponding with the location division 204 of inner side, be formed with jut 205, this jut 205 can be the bottom that nearly hand side is sticked in the sidewall 196a of restriction case 183 nearly hand sides from the open side of host body case 130, and the inside side walls 196a of this restriction case 183 is connected to location division 204.This jut 205 be extend towards the inner side oblique upper of host body case 130 can strain structure, and it is designed to heeling condition, in the time the flange part 200 of restriction case 183 being inserted to engaging track 203 and moves to the inside, the lower edge of each sidewall 196a, in nearly hand side direction inner slide, can be crossed this jut 205.And after the sidewall 196a of nearly hand side crosses, jut 205 elastic resets, to original heeling condition, engage with the face of the nearly hand side of this sidewall 196a, making to limit case 183 cannot extract from the inner side of host body case 130 towards nearly hand side.

Below, the effect of the fluid storage container 21 to present embodiment describes.Should illustrate, in Figure 24 (a), (b), (c), omit slide block 34 and liquid container 33.

As shown in figure 23, in fluid storage container 21, if sliding button 94 is shifted upward, sliding button 94 is disengaged with the engaging of recess 95 of slide block 34, aforesaid liquid accepting container 21, its the 2nd part of accommodating body 38 is positioned at installation portion 31, and cannot be fixed on movably on printer 11.Like this, user, by slide block 34 is slided towards the direction contrary with direction of insertion along its length direction, can extract slide block 34 from printer 11 (installation portion 31).

Extract by this, slide block 34 is positioned at the position of printer 11,, in the upper surface 39 of liquid container 33, accommodate overlapping position, the position that is positioned at printer 11 (the 2nd position) in body 38 with thering is the 2nd of connecting portion 43, to the outer movement of printer 11.Slide block 34 in the present embodiment, as shown in double dot dash line in Figure 23, the user outside printer 11, by the chip carrier 76 being installed on the end 34a of slide block 34 direction of insertion inner sides, moves to the position that can extract from a seat installation portion 86 for slide block 34.Therefore, in the upper surface 39 of liquid container 33, be positioned at the position of the overlapping slide block 34 in the position (the 2nd position) of printer 11 in accommodating body 38 with comprising the 2nd of connecting portion 43, have an effect as the mobile position of movement printer 11 in and between outside printer 11.

Its result is that user extracts from slide block 34 (seat installation portion 86) chip carrier 76 of shifting to outside printer 11 unload.And, for example, when being placed with on chip carrier 76 while recording chip 75, replaceablely for example, record chip 75 for what the relevant relevant information of ink that the inlet 73 of liquid container 33 is injected (, the kind of the viscosity of the form and aspect of ink, chroma, lightness and ink or the solute of ink etc.) recorded.User inserts and is installed to slide block 34 (seat installation portion 86) afterwards again by the chip carrier 76 that is placed with the chip 75 of having changed, and inserts slide block 34 along the upper surface 39 of liquid container 33 in printer 11 (installation portion 31).

By the insertion of this slide block 34, tilt and be positioned in and record chip 75 on chip carrier 76 with respect to direction of insertion, contact and be electrically connected with the electric terminal 78 of the Department of Communication Force 77 that is arranged at supply unit 32, be recorded in the relevant information recording in chip 75 and be passed to printer 11 sides.In connecting, record chip 75 and be positioned with respect to electric terminal 78.Be passed (reading) in the state of printer 11 sides being recorded in this relevant information that records chip 75, chip carrier 76 is positioned at the inside of printer 11, and a part (the 1st position) for slide block 34 is positioned at the outside of printer 11.In other words, record under the state that the relevant information of chip 75 read by printer 11 sides being recorded in, record on the position that hand that chip 75 and chip carrier 76 be positioned at user do not reach.

; as shown in Figure 24 (a); be arranged on the Department of Communication Force 77 of supply unit 32; be provided with portion of terminal 114 and protruding part 115; this portion of terminal 114 has and the electric terminal 78 that is formed at multiple electrode 75a of recording on chip 75 and contacts; this protruding part 115, in the both sides of width, extends along direction of insertion outstanding to width time.Portion of terminal 114 engages with the recess (holding section) 97 of chip carrier 76, and protruding part 115 engages with the groove-like portion 107 of chip carrier 76.On the face of wall that forms chip carrier 76 and recording on the face of chip 75 sides and be formed with above-mentioned recess 97.

Now, as shown in Figure 24 (b), in the time that slide block 34 is inserted into installation portion 31, chip carrier 76 is not departing under the state of slide block 34, in being fixed on leaf spring 79 on upper ledge 35 and pushing its protruding part 80 downwards, moves to Department of Communication Force 77.In this moves, the protruding part 115 of Department of Communication Force 77 imports chamfered section 106 and is inserted into engaging with it in groove-like portion 107, and chip carrier 76 is positioned with respect to Department of Communication Force 77.Now, the groove-like portion 107 of chip carrier 76 is as an example of the location shape portion being positioned in printer 11 and play a role.

Result is as shown in Figure 24 (a), (c), load in the chip 75 that records of chip carrier 76 and be positioned with respect to the portion of terminal 114 of Department of Communication Force 77, the multiple electric terminals 78 that are arranged at portion of terminal 114 suitably contact with multiple (being 9 herein) the electrode 75a that records chip 75.Should illustrate, when this contact occurs, because the electrode 75a that records chip 75 becomes the downward-sloping state in direction of insertion top, the therefore electric terminal 78 surface contact with it simultaneously of electrode 75a that rubs.

Below, the dependent interaction ink in fluid storage container 21 being injected describes.

To in liquid container 33 when infusing ink, as shown in Fig. 9 (a), in open-close lid 74 being displaced to uncap position, as shown in Fig. 9 (b), on the 74a of the back side of open-close lid 74, loading cladding 120 and inlet 73 is exposed.

Now, user is after inlet 73 takes off cladding 120, make coated member 121 and rotate arbitrarily angled (in present embodiment, being 180 degree) taking fixed part 123 as pivot with respect to holding liquid level 116, thereby cladding 120 is positioned on the back side 74a of open-close lid 74.In addition, in state as shown in Fig. 9 (b), the back side 74a of open-close lid 74 is in above-below direction Z than holding the position that liquid level 116 is high, therefore cladding 120 is being loaded under the state of the back side of open-close lid 74 74a to the state of connection part 125 in slightly upholding.Like this, follow connection part 125 strain (extension) and produce restoring force, forwards act on cladding 120 from open-close lid 74.About this point, in the present embodiment, hook position 110 butts of cladding 120 and open-close lid 74, therefore can suppress that cladding 120 drops from open-close lid 74 etc.In addition, be positioned at the back side 74a of the open-close lid 74 of the position of uncapping, minimum in a side that is formed with hook position 110, therefore, be positioned on the back side 74a of open-close lid 74 even if be for example attached with the cladding 120 of ink, also can suppress whole (the especially rearward region) diffusion to open-close lid 74 of this ink.

And, as shown in Figure 25 and Figure 26, inject source 126 to liquid container 33 infusing inks from liquid, when this liquid injects edge part that source 126 weldings have overlapping film etc. 128, be formed with coupler 127.In the time of infusing ink, insert and butt fluting 118 by near coupler 127 edge parts 128 that liquid injected to source 126, locate with respect to liquid container 33 thereby make liquid inject source 126, this fluting 118 is formed in the surrounding wall portion 117 of liquid container 33.As shown in figure 26, the abutment of injecting source 126 and liquid container 33 taking liquid is as inclination center, inject source 126 by inject the mode downward of coupler 127 in source 126 this liquid that tilts with liquid, thereby the ink that liquid is injected in source 126 is injected in the 1st ink chamber 151 via the inlet 73 of liquid container 33.

Now, if user's over-tilting liquid injects source 126, sometimes inject from liquid the ink that the coupler 127 in source 126 flows out and can depart from inlet 73, flow to the inlet 73 that holds in liquid level 116 around.In this case, surround and hold liquid level 116 surrounding wall portion 117 around and can stop and flow to the ink that holds liquid level 116, can suppress thus this ink and flow to outside from holding liquid level 116.And, tilt downwards towards inlet 73 respectively on left and right directions X and fore-and-aft direction Y owing to holding liquid level 116, be therefore attached to the ink holding on liquid level 116 and led re-injection entrance 73 along this inclination.

If the injection of ink finishes, as shown in Fig. 9 (a), with loading in the inlet 73 of the cladding 120 Covering Liguid host bodies 33 of the back side of open-close lid 74 74a, as shown in Figure 2, open-close lid 74 is displaced to close cover position, the injection end of job simultaneously.

In addition, as shown in figure 27, be arranged side by side under the state that uses multiple fluid storage containers 21, the fixed part 123 (fixing hole 124) of for example, coated member 121 from a fluid storage container 21 (left end) is to the distance L 6 of inlet 73, is less than the distance L 7 of the inlet 73 from the fixed part 123 of a fluid storage container 21 to other fluid storage containers 21 that are arranged side by side with this fluid storage container 21.Like this, as shown in figure 27, even taking fixed part 123 as pivot, make and the cladding 120 of coated member 121 of the corresponding setting of liquid container 33 that is positioned at left end, inlet 73 towards the liquid container 33 being arranged side by side rotates (as shown in double dot dash line in Figure 27), and this cladding 120 can not be coated this inlet 73.Should illustrate, distance L 6, L7 represent, the distance in plan view as shown in figure 27, the center of fixed part 123 (fixing hole 124) being connected with the center of inlet 73.

Below, the effect in the liquid container 33 when from inlet 73 infusing ink describes.

As shown in figure 14, if from inlet 73 infusing inks, the liquid level of the 1st ink chamber 151 can rise, and ink flows into the 2nd ink chamber 152 via wall open communication 155 simultaneously.Should illustrate, be formed at the recess 154 of the 1st ink chamber 151, on fore-and-aft direction Y, form with inlet 73 staggered positions, even when therefore foreign matter is deposited in recess 154, also can suppress flying upward of foreign matter.

Should illustrate, the 1st ink chamber 151 is communicated with via wall vent openings 156 with the 2nd ink chamber 152.Therefore, the pressure in the 1st ink chamber 151 and the 2nd ink chamber 152 is roughly the same, thereby the liquid level of ink in the 1st ink chamber 151 and the 2nd ink chamber 152 rises to roughly the same height at above-below direction Z.

The 3rd flank 158c and the 4th crosswise on flank 158d crosswise, be formed with flank open communication 161 at two ends, therefore ink flows through flank open communication 161, the liquid level of ink the 3rd crosswise flank 158c and the 4th in the both sides of flank 158d, be positioned on roughly the same position crosswise.Further, ink flows through the 1st gap that flank 158a and the 2nd forms between flank 158b and film 133 crosswise crosswise, and the liquid level of ink moves to than the 1st flank 158a and the 2nd more position of top of flank 158b crosswise crosswise.And if the liquid level of ink further rises, ink diffusion is so that ramped bottom surface 152a when rising, ink flows through the 4th～9th flank open communication 161 of intersecting flank 157d～157i rises liquid level.

Further, on intersection flank 157a～157i, be formed with respectively flank vent openings 160.Therefore,, in the 2nd ink chamber 152, the pressure in intersection space, flank 157a～157i both sides is roughly the same.Therefore, the liquid level of the ink in the 2nd ink chamber 152 also rises to height roughly the same in above-below direction Z.

Have the liquid container 33 of inlet 73, the foreign matter such as dust can be sneaked into and causes the accumulation of foreign matter itself from inlet 73 sometimes, or occurs dry etc. and cause ink itself also to become foreign matter at gas-liquid interface ink.Should illustrate, in the 1st ink chamber 151, foreign matter is deposited in subtend face 153 and recess 154.And, because wall open communication 155 separates and forms with recess 154, therefore flow into the 2nd ink chamber 152 compared with suppressing ink, more can suppress entering of foreign matter.,, the foreign matter entering from inlet 73, the foreign matter that especially size or weight are large can be trapped in the 1st ink chamber 151 than being easier to.

In addition, in the 2nd ink chamber 152, As time goes on, in front area, foreign matter can be deposited in that flank 158a～158d is upper crosswise, and meanwhile, in posterior region, foreign matter can be deposited on the 152a of bottom surface.And, 158a～the 158d of flank crosswise and the bottom surface 152a that pile up foreign matter intersect and tilt with fore-and-aft direction Y, if therefore derive ink from export mouth 69, the liquid level of ink is reduced,, along with the movement of liquid level, the foreign matter of accumulation can be mobile to a direction (descent direction).

Further, if from inlet 73 infusing inks, bubble can enter along with the injection of ink sometimes.And if bubble enters in the 2nd ink chamber 152, or dissolved gases becomes bubble in the 2nd ink chamber 152, bubble is moved upward, and arrives flank 158a～158d crosswise.About this point, in the present embodiment, because flank 158a～158d crosswise intersects with respect to fore-and-aft direction Y, so bubble can move along the 158a～158d of flank crosswise tilting, be directed into liquid level.

In addition, the ink of the 2nd ink chamber 152 flow to and derives in stream 138 from stream opening 162, then is derived from export mouth 69.Foreign matter the ink of, first deriving from stream opening 162 or bubble are caught by filter 166.Then, ink connects the 164b of stream portion and the 3rd via the 2nd and connects the 164c of stream portion and flow to bending stream portion 163.

Should illustrate, in bending stream portion 163, the flow direction of ink can change, and therefore in ink, dissolved gases can easily become bubble.About this point, by this structure, because the area of section of bending stream portion 163 is greater than the 3rd area of section that connects the 164c of stream portion, bubble the flowing to inclination stream portion 165 side shiftings along with ink therefore generating.Further, the area of section of inclination stream portion 165 is greater than the 3rd and connects the area of section of the 164c of stream portion, and forms rising ramp towards export mouth 69 sides.Therefore, the bubble producing in bending stream portion 163 moves to export mouth 69 sides along inclination stream portion 165, is exported together with ink from export mouth 69.

Below, the effect of float-controlled valve 131 is described.

State is as shown in figure 19, the state of the line EL top when far away from threshold value surplus of the ink level line IL in ink chamber 137, what represent is for from fluid jetting head 24 to paper S, thereby injection ink can print continuously, and the surplus of ink chamber's 137 interior inks is in very sufficient state.Therefore, under the state shown in this Figure 19, the 1st elastic force the 2nd elastic force of helical spring 195 and the buoyancy of float member 181 and that be more than or equal to helical spring 184, therefore float member 181 makes valve body 182 be connected to valve port 192 below can not being expressed to by the 1st elastic force of helical spring 184.

That is, in this case, as shown in figure 19, the buoyancy that each gas compartment 187 of float member 181 produces and be greater than the 1st elastic force of helical spring 184, float member 181 is in the state swimming in the position that separates upward from valve body 182.On the one hand, valve body 182 can not pushed downwards by helical spring 184 via float member 181, therefore the 2nd elastic force upward that valve body 182 is only subject to being produced by helical spring 195, leaves upward and is positioned at from valve port 192 and open the valve position of opening of deriving stream 138.

Then, proceed printing from state as shown in figure 19, the surplus of ink chamber's 137 interior inks can reduce gradually thus, line EL when if the metal line IL of ink approaches threshold value surplus, as shown in figure 28, that formed the buoyancy of float member 181 and the 2nd elastic force of helical spring 195 and form balanced state each other with the 1st elastic force of helical spring 184.Therefore, float member 181 is pushed downwards under the effect of the 1st elastic force of helical spring 184, and the press section 189 of its lower surface is positioned at out the valve body 182 of valve position from top butt.Should illustrate, now, float member 181 is connected to valve body 182 from top, but does not also reach this valve body 182 degree of closing valve position displacement downwards that makes.

Then, proceed printing from state as shown in figure 28, the surplus of the ink in ink chamber 137 can further reduce thus, be positioned at the below of threshold value surplus line EL once the metal line IL of ink, as shown in figure 29, the 1st elastic force the 2nd elastic force of the buoyancy of float member 181 and helical spring 195 and that be less than helical spring 184.Therefore, float member 181 is further pushed downwards under the effect of the 1st elastic force of helical spring 184, and the press section 189 of lower surface pushes the valve body 182 in driving valve position downwards.Finally, valve body 182 is shifted towards the valve position that closes of inaccessible valve port 192.

Like this, clog because valve port 192 is blocked, therefore derive stream 138 also by obturation, so that ink does not flow to the downstream of valve port 192.Therefore, ink can not flow in the liquid chamber 53 that is disposed in the downstream of deriving stream 138, cause surplus test bar 45 to be moved and be maintained at the state of the light between illuminating part and the light accepting part that covers sensor 68, the surplus that therefore sensor 68 detects ink is less than threshold value surplus.And, once receive this testing result, new ink is injected in ink chamber 137 from inlet 73, the metal line IL of the ink in ink chamber 137 top of line EL in the time of threshold value surplus again, therefore the buoyancy of float member 181 has exceeded the 1st elastic force of helical spring 184, thereby float member 181 is floated with the state separating upward from valve body 182.

Now, float member 181 is by the 1st elastic force application of force downwards of helical spring 184, pushed and be positioned at the valve body that closes valve position 182 of obstruction valve port 192 downwards by the press section 189 of float member 181, when it is for a long time in the time closing valve position, even because of after float member 181 is disengaged from the extruding of top, this valve body 182 is still attaching state with respect to valve port 192 sometimes.About this point, in the present embodiment, the 2nd elastic force of helical spring 195 is driven valve position to valve body 182 application of forces in closing valve position, even if therefore valve body 182 is temporarily attached at valve port 192 towards top, also can depart from from valve port 192, thereby this attaching state is disengaged.

In addition,, if crossed suddenly from inlet 73 to the interior infusing ink of ink chamber 137, the feed pressure that while injection, ink flows in ink chamber 137 may strengthen.Therefore, thus the peristome 185a that blocks framework 185 in float-controlled valve 131 forms the film member 186 of gas compartment 187, if directly bear this strong feed pressure, probably can be damaged etc.About this point, in the present embodiment, and be formed with in the 2nd ink chamber 152 being separated by next door 150 between the 1st ink chamber 151 of inlet 73 and dispose float-controlled valve 131.Therefore, float-controlled valve 131 can avoid the ink injecting from inlet 73 directly to fall from top.

In addition, cross suddenly when being formed on wall open communication 155 on next door 150 from the 1st ink chamber's 151 side inflows the 2nd ink chamber 152 side when ink, this feed pressure probably also can make the film member 186 of the float member 181 in float-controlled valve 131 suffer damage.About this point, in the present embodiment, with the state not relative with the fore-and-aft direction Y of inflow direction that flows into the ink in the 2nd ink chamber 152 via wall open communication 155, i.e. the state along fore-and-aft direction Y with film member 186, is configured in float member 181 in the 2nd ink chamber 152.Therefore, flow into the feed pressure of the ink in the 2nd ink chamber 152 from wall open communication 155, act on the film member 186 of float member 181 in the mobile mode on fore-and-aft direction Y of the face along film member 186.

It is worth mentioning that, due to aging, in the film member 186 in float member 181, have part damage etc., in multiple (in present embodiment being 4) gas compartment 187, have and severally cannot form again closed structure.And in this case, the buoyancy of float member 181 entirety can diminish, therefore the valve function of float-controlled valve 131 may produce fault.But, in present embodiment, even the in the situation that of a surplus gas compartment only 187, the buoyancy that this gas compartment 187 produces and the 2nd elastic force of helical spring 195 with, in the time that the surplus of ink is more than or equal to threshold value surplus, also can be set as being more than or equal to the 1st elastic force of helical spring 184.Therefore,, even in the situation that gas compartment 187 only remains one, float-controlled valve 131 also can be brought into play its function as valve without barrier.

In addition,, when float member 181 is floated on above-below direction Z along with the variation of ink chamber's 137 interior ink remaining amounts, by bar-shaped portion 190 being inserted in the jack 198a of cylindrical portion 198, can make float member 181 be aligned at fore-and-aft direction Y and left and right directions X.And from the two sides, front and back of framework 185, outstanding protuberance 188 is inserted into the guiding slotted hole 201 of restriction case 183, therefore can limit float member 181 and rotate centered by bar-shaped portion 190.Further, be placed with the float member 181 of helical spring 184, because the upper wall of the cylindrical portion 198 in restriction case 183 is limited to float to the valve position position closer to the top of opening than valve body 182.

Further, while floating on the fore-and-aft direction Y of float member 181 in ink chamber 137 and left and right directions X, for example film member 186 contacts with the face of the relative sidewall 196a in restriction case 183, can be restricted because of the medial surface of criss-cross plate-like portion 191 and cylindrical portion 198 mutual butt in a horizontal direction.; in float member 181; in the jack 198a of cylindrical portion 198, insert under the state of bar-shaped portion 190; spacing distance between the top edge of the radiation direction of plate-like portion 191 and the medial surface of cylindrical portion 198, is less than the spacing distance between film member 186 and the inner face of the each sidewall 196a in left and right of restriction case 183.Therefore, the film member 186 of float member 181 contacts and can be restricted with the face of restriction two side 196a relative with film member 186 in case 183.About this point, plate-like portion 191 plays a role as an example of restriction abutting part, this restriction abutting part to restriction case 183 and float member 181 in the horizontal direction mutually the face between relative opposite face contact and limit.

In addition, in this case, about the sidewall 196a of control cabinet relative on left and right directions X 183 and the thin film component 186 of float part 181, owing to being formed with the notch 199 of rectangle on the sidewall 196a at restriction case 183, therefore can prevent that film member 186 from sliding and being damaged to the inner face of the sidewall 196a of restriction case 183.

In addition, if particularly float member 181 is floated upward in restriction case 183, the ink that may limit in case 183 is pushed from below by float member 181, causes ink pressure to raise.About this point, in the present embodiment, due to the rising of this ink pressure, can make ink flow out from the through hole 202 and the notch 199 that are formed at multiple places of limiting case 183, therefore can suppress the unnecessary rising of ink pressure.

By above embodiment, the present invention can obtain following effect.

(1) fluid storage container 21, it is upper that its inlet 73 is formed at the 1st position (the 1st accommodates body 37) outside the printer 11 that is arranged in liquid container 33, therefore can be fixed in infusing ink under the state of printer 11 at liquid container 33.So can prevent infusing ink time, liquid container is damaged or inner remaining liquid spills.In addition,, owing to being positioned at the 2nd position (the 2nd accommodates body 38) of printer 11 in liquid container 33, in the time that stationary state is removed, can improve liquid container 33 and can not fall but remain on the probability on printer 11.

(2) fluid storage container 21, can adopt the slide block 34 sliding with respect to liquid container 33 to make to record chip 75 and from printer 11, move in printer 11, this records chip 75 and is recording to be injected into and be fixed and the relevant information of ink in irremovable liquid container 33.Therefore, when recording chip and move in liquid consuming device, if this records chip and is for example set in advance as with electric terminal 78 grades that are arranged in liquid consuming device and contacts, can correctly transmit to printer 11 relevant information of the ink that is injected into liquid container 33.In addition, the chip carrier 76 having for the mobile position of slide block 34, by record chip 75 be positioned in printer 11 outer after, can easily the chip 75 that records of mounting be inserted in printer 11 by the slip of slide block 34.

(3), because slide block 34 has covered inlet 73, the lid that therefore need not design in addition other inlet 73 use just can suppress foreign matter and enter inlet 73.

(4) cover in the state of inlet 73 at slide block 34, immediately do not make slide block slide, also can realize the open and close of inlet 73 by the displacement of set open-close lid 74.

(5) cover displacement at open-close lid 74 to the state of the position of uncapping from closing, open-close lid 74 is positioned at printer 11 sides with respect to inlet 73.Therefore,, in the time of the operation of carrying out to inlet 73 infusing inks, open-close lid 74 can not become obstruction.

(6) cover position because open-close lid 74 can stably maintain to close, therefore can prevent from opening because of carelessness open-close lid 74 and inlet 73 is exposed.

(7), because chip carrier 76 is positioned in the direction of intersecting with the moving direction at mobile position in printer 11, therefore load recording chip 75 and also can accurately locate at the interior quilt of printer 11 in chip carrier 76.Therefore, for example, be arranged at electric terminal 78 in printer 11 and under the state that chip 75 can not misplace, recording chip 75 with this and contact with respect to recording, can be delivered in printer 11 with high-accuracy so be recorded in the relevant information that records chip 75.

(8) chip carrier 76 can be suppressed to the movement of the glide direction of slide block 34, therefore can in printer 11, the glide direction with respect to slide block 34 accurately be located.In addition, load in chip carrier 76 to record chip 75 inclined with respect to the glide direction of slide block 34, move and electrical connection with it on the electric terminal 78 friction limit, limit on record chip 75 (electrode 75a) being therefore for example arranged in printer 11.Therefore, the reliability of conductivity improves.

(9) user is by inlet 73 during to the 1st ink chamber 151 (ink chamber 137) infusing ink of liquid container 33, even if this ink flows to inlet 73 around, this ink also can be held liquid level 116 and accept.And, due to hold liquid level 116 towards inlet 73 downwards (gravity direction) tilt, can be trickled and be imported into inlet 73 along the liquid level 116 that holds tilting thereby hold ink that liquid level 116 catches.Therefore, in the inlet 73 to fluid storage container 21 when infusing ink, even if the surrounding of inlet 73 has under ink droplet, also can prevent this ink from the surrounding of inlet 73 flow to fluid storage container 21 outside and around polluting.

(10), by surrounding the surrounding wall portion 117 of the surrounding of holding liquid level 116, in the time of the 1st ink chamber 151 infusing ink to liquid container 33, can prevent that this ink from overflowing the outside of holding liquid level 116.

(11) user injects source 126 via inlet 73 during to the 1st ink chamber 151 infusing ink from liquid, thereby can locate liquid and inject source 126 by making liquid inject fluting 118 that source 126 is connected to surrounding wall portion 117.Like this, when user injects source 126 to the 1st ink chamber 151 infusing ink from liquid, can stablize and inject this ink.

(12) cladding 120 of covering inlet 73 is fixed on liquid container 33 via connection part 125 and fixed part 123.Therefore, can reduce the risk of losing this cladding 120 in the time that inlet 73 takes off cladding 120.In addition,, by with the coated inlet 73 of cladding 120, can suppress ink and evaporate and sneak into foreign matter the 1st ink chamber 151 from the 1st ink chamber 151.

(13), when infusing ink, can on the back side 74a of open-close lid 74 that is positioned at the position of uncapping, load cladding 120.Like this, user when infusing ink, for example, can prevent because one hand is held cladding 120 infusing ink under the occupied state of this hand in the 1st ink chamber 151.

(14), in the time loading cladding 120 on the open-close lid 74 in the position of uncapping, even if there is ink to be attached on this cladding 120, also can suppresses this ink by shielding portion and leak to the outside of open-close lid 74.

(15) cladding 120 can be positioned in the region of back side 74a of the open-close lid 74 in the position of uncapping with the state of being accommodated.Further, even adhered to ink on the cladding 120 of mounting, due to the back side 74a of open-close lid 74 towards inlet downwards (gravity direction) tilt, therefore also can prevent the whole regional diffusion of this ink to back side 74a.

(16) connection part 125 bendings of coated member, therefore it can storage property be placed on well and holds on liquid level 116.In addition, compare the straight situation of connection part 125 shape, be attached with the situation of ink at this cladding 120 when inlet 73 unloads cladding 120, this ink can more be difficult to flow to connection part 125.

(17) fixed part 123 is fixed on and holds place higher than inlet 73 on liquid level 116, during therefore to liquid container 33 infusing ink, is difficult to be attached on the fixed part 123 of coated member 121 holding ink mobile on liquid level 116.Like this, for example, can prevent from occurring to solidify because ink ink on fixed part 123 adheres to, cause affecting the stationary state of fixed part 123.

(18) in the time that user wants the ink of multiple kinds to be injected into multiple fluid storage containers 21 (ink chamber 137), the cladding 120 that can prevent the design corresponding to a fluid storage container 21, can cover in the inlet 73 of other fluid storage containers 21 that are arranged side by side with this fluid storage container 21.Thus, can prevent from covering due to the cladding 120 designing corresponding to a fluid storage container 21 inlet 73 of other fluid storage container 21, and cause ink to be sneaked into by cladding 120 in other the ink chamber 137 of fluid storage container 21.

(19) on the position of wall open communication 155 in reversing with respect to inlet 73, and be positioned on the position of leaving subtend face 153.Therefore, the ink injecting from inlet 73 flows in the 2nd ink chamber 152 by wall open communication 155, and the foreign matter of sneaking into from inlet 73 or at the foreign matter of the 1st ink chamber 151 interior generations is more difficult by wall open communication 155 than ink.That is, owing to can easily foreign matter being stayed to the 1st ink chamber 151, so in the 2nd ink chamber 152 flow into be to have suppressed the ink that foreign matter is sneaked into.Therefore, sneaking into the situation of foreign matter or the situation at inside generation foreign matter from inlet 73, can both reduce from export mouth 69 and derive the risk of the foreign matter of sneaking into, can derive well ink no matter be simultaneously.

(20) subtend face 153 is formed with to the recess 154 of gravity direction depression, even if the foreign matter being therefore detained in the 1st ink chamber 151 deposits in time, also can make this foreign matter be deposited in recess 154., under the state in foreign matter is deposited in recess 154, during from inlet 73 infusing ink, the foreign matter that can suppress to pile up flies upward recess 154 in recess 154.

(21) foreign matter that can make to sneak into or produce is deposited in recess 154.And because recess 154 is arranged on the position of staggering with inlet 73 in the direction of intersecting with gravity direction, therefore, can further suppress from inlet 73 infusing ink time, the foreign matter of recess 154 interior accumulations flies upward.

(22) by making stream opening 162 and the distance L 1 in next door 150 be less than the distance L 2 of upper end and wall open communication 155 lower ends of recess 154, thereby can form stream opening 162 near on the position in next door 150.Therefore, can reduce and enter the risk that derives stream 138 from the 1st ink chamber's 151 sides via wall open communication 155 to the foreign matter of the 2nd ink chamber's 152 sides in the interior deposition of stream opening 162 together with ink.

(23), even if having foreign matter to enter in the 2nd ink chamber 152 or in the time of the 2nd ink chamber 152 interior generation foreign matter, also can make the foreign matter of the 2nd ink chamber's 152 interior depositions be deposited in crosswise on flank 158a～158d.Therefore, can further suppress from exporting to the ink of deriving stream 138 and sneak into foreign matter than the stream opening 162 of the more close gravity direction side of flank 158a～158d crosswise.

(24) flank 158a～158d extends along the direction of intersecting with respect to above-below direction Z and fore-and-aft direction Y crosswise, therefore, be accompanied by the minimizing that is contained in the ink in the 2nd ink chamber 152, be piled up in the foreign matter of flank 158a～158d crosswise and also can be concentrated in one direction.

(25) adopt the float-controlled valve 131 that unsteady float member 181 is shifted valve body 182 with the variation of ink remaining amount, if for example there is foreign matter to pile up,, due to the weight of the foreign matter of piling up, probably can produce faulty operation in float member 181.About this point, upper than the 158a～158d of flank crosswise of the more close antigravity direction of float-controlled valve 131 side owing to can making foreign matter be deposited in to be arranged at, therefore can suppress the foreign matter of deposition in the 2nd ink chamber 152 in the interior accumulation of float member 181.

(26) even along with being contained in the variation of the ink remaining amount in the 2nd ink chamber 152, be piled up in the 3rd crosswise flank 158c and the 4th crosswise the foreign matter of flank 158d be moved and from the 3rd crosswise flank 158c and the 4th crosswise flank 158d fall, also can make foreign matter avoid float-controlled valve 131 and fall.

(27) can make the ink of deriving from stream opening 162 by backward float-controlled valve 131 side flow of filter 166., for example, in the foreign matter the ink in inlet 73 is sneaked into the 1st ink chamber 151, the larger foreign body retention of relative size, in the 1st ink chamber 151, is deposited on the 158a～158d of flank crosswise of the 2nd ink chamber 152 simultaneously.So to derive the relative size of the foreign matter of sneaking into the ink of stream 138 less owing to exporting to from stream opening 162, therefore, compare and sneak into large foreign matter, even enter foreign matter from stream opening 162, also can suppress to derive stream 138 blocked.And, by being flowed through, ink is arranged at the filter 166 of deriving stream 138, can further reduce the foreign matter of sneaking into the ink of deriving from export mouth 69.

(28) area of wall open communication 155 is less than the area of inlet 73, while therefore sneaking into the large foreign matter of size from inlet 73, can reduce the risk that foreign matter is crossed wall open communication 155 and entered the 2nd ink chamber 152.

(29) bubble in ink is easily trapped in the sweep of deriving in stream 138.About this point, the bubble that is positioned at bending stream portion 163 is directed to export mouth 69 sides by inclination stream portion 165.Therefore, for example can reduce bubble because being stranded in bending stream portion 163 and become and blocks greatly the risk that derives stream 138, thereby can in reduction aeration, derive ink.

(30) by make the ink filter 166 of flowing through before flowing to the bending stream portion 163 of easy delay bubble, can catch in advance the bubble having generated.

(31) bubble producing in ink chamber 137, to the upper side shifting of gravity direction, therefore by making stream opening 162 at bottom surface 152a opening, can reduce bubble and enter the risk that derives stream 138 from stream opening 162.

(32) by forming flank 158a～158d crosswise, can strengthen ink chamber 137.Further, flank 158a～158d extends along the direction of intersecting with horizontal direction crosswise, is therefore contained in while producing bubble in the ink of ink chamber 137, and bubble can move along flange part 158a～158d crosswise., can reduce bubble by flank 158a～158d catches crosswise risk.

(33) can make the bottom surface 152a of ink chamber 137 tilt along inclination stream portion 165.That is, stream opening 162 sides of inclination stream portion 165 are lower, therefore the ink in ink chamber 137 can be concentrated on to stream opening 162 sides.

(34) area of section of inclination stream portion 165 is large, therefore can reduce the risk because causing inclination stream portion 165 to get clogged at bending stream portion 163 interior generation bubbles.

(35), even produce bubble in wall open communication 155, because the upper surface 155c0 of antigravity direction side tilts, therefore can reduce bubble and be trapped in the risk of wall open communication 155.

(36) by being formed at the wall vent openings 156 in next door 150, can reduce the pressure differential of the 1st ink chamber 151 and the 2nd ink chamber 152.Further, be formed at the wall vent openings 156 in next door 150 than the more close end face 137b of flank vent openings 160 that is formed at intersection flank 157a～157i, the ink that therefore can reduce in the 2nd ink chamber 152 enters the risk in the 1st ink chamber 151 from wall vent openings 156.

(37) by forming positioning convex strip 141, can suppress the skew of air flue formation film 147, it is easily bonded on snake ditch 142,143.

(38) by the 1st stream formation recess 168a of lower surface 40 that is formed at host body case 130, filter 166 being installed, can easily change filter 166.

(39) be disposed at the float-controlled valve 131 in the 2nd ink chamber 152 of liquid container 33, when the film member 186 of the peristome 185a of its barrier gas chamber 187 can directly not be subject to infusing ink, flow into from inlet 73 feed pressure that the ink in the 2nd ink chamber 152 produces., the feed pressure of ink is applied to it along the face of film member 186.Therefore, even via inlet 73 from outside the 1st interior mistake of ink chamber 151 infusing ink suddenly to ink chamber 137, the feed pressure that also can prevent this ink via the 1st ink chamber 151 towards the direction strong effect of the film member 186 of the float member 181 in extruding the 2nd ink chamber 152 on this film member 186.Therefore, be disposed at inner float-controlled valve 131 and can, because the feed pressure of the ink from outside injection suffers damage, can not maintain appropriate valve events.

(40) because float-controlled valve 131 is configured in the 2nd ink chamber 152, the 2nd ink chamber 152 and the 1st ink chamber 151 that is formed with inlet 73 are separated by next door 150, therefore can avoid the ink injecting via inlet 73 from outside directly to fall facing to float-controlled valve 131, about this point, also can further reduce the risk that float-controlled valve 131 is damaged.

(41) for example, cause that air-tight state is destroyed even if suppose that 1 gas compartment 187 in multiple (being 4) gas compartment is damaged etc., as long as the volume summation of remaining other gas compartments 187 is designed to can produce to the volume of the gas compartment 187 of required buoyancy in float member 181, just can maintain well the function of float-controlled valve 131.

(42) especially after long-time, be less than threshold value surplus and valve body 182 is positioned at the state that closes valve position from ink remaining amount, change into while making ink remaining amount reach state more than threshold value surplus via inlet 73 infusing inks, can suppress valve body 182 and be attached at and close valve position, and can make this valve body 182 from closing valve position to opening valve position rapid traverse.

(43) can prevent that by the annular wall portion 196 of restriction case 183 feed pressure of the ink that flows into the 2nd ink chamber 152 from directly acting on float member 181, can reduce float member 181 simultaneously in the time that above-below direction Z floats, with annular wall portion 196 surface contact states of restriction case 183 under, because slip produces the risk of moving resistance.

(44) can reduce float member 181 in the time that above-below direction floats, film member 186 slides and the risk that is damaged in the annular wall portion 196 of restriction case 183.

(45) float member 181 is in the time that above-below direction Z floats, can allow ink to flow between the inner side of annular wall portion 196 of restriction case 183 and outside via through hole 202, therefore can change the quick condition flexibly that guarantee float member 181 according to the surplus of ink.

(46) can reduce restriction case 183 and float member 181 in a horizontal direction between relative subtend face,, film member 186 and the risk that sidewall 196a is close to because of the surface tension of ink, therefore can maintain the appropriate valve events of float-controlled valve 131 well.

(47) only make float member 181 be extruded with less stroke with respect to valve body 182, can make valve body 182 be shifted driving valve position and close between valve position, therefore can contribute to the miniaturization of float-controlled valve 131.
