Next, maximum amplitude of fluctuation and the state from ink tank 43 to jet head liquid 32 supply inks of the liquid level 51 of ink are described.
The tape deck 12 of present embodiment utilizes water-head to be contained in ink feed in ink chamber 50 to jet head liquid 32.Therefore,, when liquid level 51 changes significantly on above-below direction Z, cannot to jet head liquid 32, supply well ink from ink tank 43.Specifically, when jet head liquid 32 is positioned at than the much lower position of liquid level 51, may be from jet head liquid 32 leak ink, on the other hand, when jet head liquid 32 is positioned at than liquid level 51 high a lot position, may be by ink feed to jet head liquid 32.
In the tape deck 12 of present embodiment, when the liquid level 51(of ink is with reference to Fig. 6) above-below direction Z on maximum amplitude of fluctuation while being more than or equal to 75mm, cannot supply well ink to jet head liquid 32.; the situation of for example having held the ink of maximum in Yu ink chamber 50 correspondingly configures in the situation of jet head liquid 32; while causing liquid level 51 to decline when ink is consumed, even if remain ink in ink chamber 50, also cannot be by ink feed to jet head liquid 32.In addition, for example the ink in Yu ink chamber 50 is consumed and the situation that causes liquid level 51 to decline correspondingly configures jet head liquid 32, and in the situation that held the ink of maximum, ink can leak from jet head liquid 32.
On the other hand, if make the maximum amplitude of fluctuation on the above-below direction Z of liquid level 51 of ink be less than or equal to 70mm, even in the situation that held the ink of maximum in ink chamber 50, even if or in the situation that the liquid level 51 of the ink in ink chamber 50 declines, also ink feed can be arrived to jet head liquid 32.
But, in the situation that the maximum amplitude of fluctuation of liquid level 51 is 70mm, sometimes due to the assembly error of jet head liquid 32 and ink tank 43 or foozle and cannot supply well ink.Therefore,, if make maximum amplitude of fluctuation be less than or equal to 55mm, even if how much there is some assembly errors or foozle, also ink can be fed to jet head liquid 32 well.And, in the situation that making maximum amplitude of fluctuation be less than or equal to 40mm, even if for example how many installation surfaces of tape deck 12 exists some to tilt, also can to jet head liquid 32, supply well ink from ink tank 43.
Therefore, as shown in figure 10, in the present embodiment, make the height the above-below direction Z from lower limit scale 64a to upper limit scale 64b be less than or equal to 40mm.That is,, when the liquid level 51 of ink drops to lower limit scale 64a, user, from inlet 52 infusing inks, makes the liquid level 51 of ink rise to upper limit scale 64b.Therefore,, because the amplitude of fluctuation of ink level 51 that can be when conventionally using jet head liquid 32 is set as being less than or equal to 40mm, therefore the ink in ink chamber 50 can be supplied to jet head liquid 32 well.
In addition, by the lower end (example of bottom surface) from being formed on the opening of the export mouth 59 ink chamber 50 to the height setting on the above-below direction Z of upper limit scale 64b for being less than or equal to 55mm.Therefore, even if for example user does not notice that the liquid level 51 of ink has dropped to lower limit scale 64a and proceeded printing, the in the situation that of remaining ink in ink chamber 50, also can be to jet head liquid 32 supply inks.
Next, the shape of ink chamber 50 is described.
If the height on the above-below direction Z of limit ink chamber 50, can be fed to jet head liquid 32 well by ink, the amount that is still contained in the ink in ink chamber 50 can tail off.Therefore, the ink tank 43 of present embodiment, by increasing the size on fore-and-aft direction Y and increasing horizontal sectional area, has been guaranteed to be contained in the quantity of ink in ink chamber 50.
Specifically, the size on the left and right directions X of ink chamber 50 is assumed to depth D, the size on fore-and-aft direction Y is assumed to width W, the size on above-below direction Z is assumed to height H.So, ink chamber 50 has following region: when having derived 5% ink of the saturation that is equivalent to be contained in ink chamber 50 from export mouth 59, the 5%(that the amplitude of fluctuation of the liquid level 51 of the ink in ink chamber 50 is less than or equal to the cubic root that can be contained in the saturation in ink chamber 50 for example, is at least the region of the height the above-below direction Z from lower limit scale 64a to upper limit scale 64b in Figure 10).In addition, in the following description, the condition that the shape of Jiang Yu ink chamber 50 is relevant is called shape condition, and the saturation that can be contained in ink chamber 50 is called maximum capacity.
For example, in the situation that ink chamber 50 is depth D, the width W on fore-and-aft direction Y, the height H on above-below direction Z on left and right directions X, all equate the cube shaped of (D=W=H), no matter where the liquid level 51 of ink is positioned at, and all meets shape condition.Specifically, in the situation that being cube shaped, derived maximum capacity 5% time the amplitude of fluctuation (0.05 * D * W * H/(D * W) of liquid level 51) with 5%(0.05 * (D * W * H) 1/3 of the cubic root of maximum capacity) equate.
Therefore,, if compare longer rectangular shape on fore-and-aft direction Y or left and right directions X with cube shaped, meet shape condition.That is,, in the situation that the height H of ink chamber is less than depth D and width W, meet shape condition.Specifically, the area of the floor space of ink chamber 50 (D * W) or liquid level 51 (horizontal sectional area of ink chamber 50) is more than or equal to the quadratic power of height H, meets shape condition.But, even if height H is greater than one in depth D and width W, sometimes also meet shape condition.For example,, even if half that depth D is height H, if width W is more than or equal to the twice of height H, meets shape condition.
Next, the amplitude of fluctuation of the ink level 51 in the ink chamber 50 while having derived 5% the ink that is equivalent to maximum capacity is described.
If while having derived 5% the ink that is equivalent to maximum capacity, the minimum change amplitude of the ink level 51 in ink chamber 50 is (following, referred to as " minimum change amplitude ") be more than or equal to maximum capacity cubic root 6%, cannot guarantee to be fully contained in the amount of the ink in ink chamber 50.
On the other hand, if minimum change amplitude be less than or equal to maximum capacity cubic root 5%, can in ink chamber 50, hold fully ink, but preferably minimum change amplitude be less than or equal to maximum capacity cubic root 4%.
Below, operation when ink tank 43 is fixed on apparatus main body 13 is described.
As shown in Fig. 5, Figure 16, first from the opening of container 42b of can container 42, insert ink tank 43, make the concavo-convex chimeric contraposition of carrying out of positioning convex portion 67a, 67b and location indentations 63a, 63b.Now, the part in the left side of film 49 is folded puts in can container 42.And, mounting screw 61 and tank sticking department 62 and screw part 66 are screwed togather, ink tank 43 is fixed in can container 42.That is, thus can container 42 by from outer side covers ink tank 43 protection ink tanks 43.And, by being inserted into and having passed, manage 31 choke valve 45 and be arranged in can container 42, and the top of pipe 31 is inserted in export mouth 59.
Then, as shown in figure 23, the can container 42 and installed surface 13a contraposition of ink tank 43 will have been fixed.That is, make can container 42 surround first rib 34 is installed, make boss portion 38 coordinate with auxiliary section 69 simultaneously, and reinforcement installation flank 34f is coordinated with cooperating recesses 72.
In addition, as shown in Figure 7, when making to have installed after the can container 42 and installed surface 13a contraposition of ink tank 43, the position of absorption piece 39 between inlet 52 and apparatus main body 13.In addition, absorption piece 39 has the thickness that is greater than installation flank 34a on left and right directions X.Therefore the absorption piece 39, being arranged between apparatus main body 13 and ink tank 43 is compressed and generation compression by apparatus main body 13 and ink tank 43 clampings.
And as shown in figure 23, under the state of can container 42 and installed surface 13a contraposition, container lock bonding part 68a-68e is consistent with screw bosses portion 37.Therefore,, after screw 36 and container lock bonding part 68a-68e are screwed togather, each container lock bonding part 68a-68e and screw bosses portion 37 are screwed together, and can container 42 is fixedly connected with apparatus main body 13.
Like this, be fixedly connected with under the state of can container 42 and apparatus main body 43, the region exterior position 49a from housing peristome 48a to the film 49 exposing outside, 49b, 49c(are with reference to Figure 13) gap that is arranged between ink tank 43 and can container 42 holds.The region exterior position 49d(of the film 49 exposing to the outside of can container 42 in addition, is with reference to Figure 14) under the folded state of putting in the gap being arranged between ink tank 43 and can container 42, be received (with reference to Fig. 4).Therefore, in can container 42, be fixedly connected under the state on apparatus main body 13, film 49 is not exposed to the outside of can container 42.
In addition, when can container 42 is installed on apparatus main body 13, the opening of container 42b of can container 42 is covered by apparatus main body 13.Therefore, apparatus main body 13 and can container 42 be as can be from an example performance function of the guard block of outer side covers, protection ink tank 43, and apparatus main body 13, can container 42, ink tank 43, absorption piece 39 have formed an example of liquid delivery system.
Then, in can container 42, be fixedly connected under the state on apparatus main body 13 the mode mounting cover 44 coordinating with sliding contacting part 80 with rail portion 76a, 76b from the rear of can container 42.
In addition, as shown in Figure 28, Figure 30, first the backstop protuberance 80a of lid 44 coordinates with the second backstop recess 78b that is positioned at rear side, and lid 44 is positioned at non-hidden position B.Then, when the lid 44 that is positioned at non-hidden position B is further forwards pushed away, backstop protuberance 80a climbs up the medial surface of front side of the chamfering of the second backstop recess 78b, thereby removes the cooperation of backstop protuberance 80a and the second backstop recess 78b, makes to cover 44 and forwards moves.
So as shown in Figure 27, Figure 29, the backstop protuberance 80a of lid 44 coordinates with the first backstop recess 78a, lid 44 is positioned at hidden position A.In addition, medial surface chamfering due to the first backstop recess 78a rear side, therefore in the situation that be positioned at the lid 44 of hidden position A and be pushed rearward, backstop protuberance 80a climbs up the medial surface of rear side of the chamfering of the first backstop recess 78a, thereby remove the cooperation of backstop protuberance 80a and the first backstop recess 78a, make to cover 44 and rearward move.
Next, illustrate to operation during infusing ink in ink tank 43.
When the liquid level 51 of the ink in being contained in ink tank 43 has dropped to lower limit scale 64a, user makes to cover 44 and slides and move to non-hidden position B(with reference to Figure 28 from hidden position A).So, be positioned at packaged unit 58 and the mounting portion 75 that the lid 44 of hidden position A covers and reveal.
Then, user moves to mounting portion 75 by the chimeric packaged unit 58 in the top with cylinder portion 53, and from inlet 52 infusing inks.In addition, can confirm the ink being injected into from the window portion 42a of can container 42.
The in the situation that of causing overflowing injecting along with ink, leak ink forms face 54 via inlet and flows and be blocked protuberance 55 interceptions to the direction away from apparatus main body 13.In addition, even if the amount of leak ink is many, just in case crossed interception protuberance 55, leak ink also can, along stage portion 54a diffusion, be leaked direction and change.In addition, even for example in the situation that ink disperses to apparatus main body 13 sides, also can absorb the ink leaking by the absorption piece 39 being arranged between apparatus main body 13 and tank unit 27.
And when liquid level 51 has risen to upper limit scale 64b along with the injection of ink, user finishes the injection of ink, the packaged unit 58 that makes to be positioned in mounting portion 75 is back to a portion 53, and makes to cover 44 and forwards slide and move and move to hidden position A.
Next, the operation in the ink chamber 50 that is injected into ink is described.
As shown in figure 13, when having injected ink from inlet 52, ink is intersected flank 101-103 interception rearward being guided.In addition, on intersection flank 101-103, be formed with the first extension 104.Therefore, by the first extension 104, suppressed ink and flowed to the direction of crossing intersection flank 101-103 towards front side, ink is more easily rearward flowed.
Then, ink rearward flows by the gap between vertical flank 111-118 and step bottom surface 50b.Therefore,, when the liquid level 51 in ink chamber 50 rises along with the injection of ink (with reference to Fig. 6) and arrived the position that is formed with vertical flank 111-118, first rearward the flowing of ink hindered by the first vertical flank 111.Therefore, the rearward mobile change of ink.
That is, upper at the mobile flow direction of ink (being along step bottom surface 50b towards rearward direction in the present embodiment), than the rearward position of vertical flank 111-118 downstream, ink generation vortex.Therefore, ink produces mobile to the direction (top) of intersecting with step bottom surface 50b.Therefore, for example, in the situation that minute having injected ink several times, the ink first injecting, because the vortex of the mobile generation of the ink along with rear injection is stirred, mixes with the ink of rear injection simultaneously.
Ink tank 43 can be held ink in large quantities, from infusing ink before to next needing the needed time of infusing ink longer.Therefore, for example,, in the situation that the paint ink of an example as ink is contained in ink chamber 50, the pigment composition of ink can precipitate sometimes.But owing to having stirred by injecting new ink from inlet 52 ink remaining in ink chamber 50, so the deviation of the concentration in ink chamber 50 reduces.
Next, illustrate at ink and be contained in and under the state that can use in ink tank 43, carry multifunctional equipment 11(tape deck 12) time operation.
The multifunctional equipment 11(tape deck 12 that has held ink in carrying ink tank 43), time, first make choke valve 45 become and close valve state.Then, when under this state, such as turned upside down packing, have multifunctional equipment 11(tape deck 12) corrugated fibre box etc. time, as shown in figure 31, ink tank 43 becomes ink chamber 50 and compares the attitude that is positioned at top with air chamber 200.
So ink is because water-head starts from ink chamber's 50 sides of ink tank 43 via connected entrance 210 to air chamber 200(the first air cell 200a specifically) side flow.Then, in normal circumstances, due to the negative-pressure balancing of water-head and ink chamber 50 in the near future, so ink mobile stopping to air chamber 200 sides via connected entrance 210 from ink chamber's 50 sides.
; as shown in figure 31; in air chamber 200 sides; the ink that the first air cell 200a being directly communicated with ink chamber 50 via connected entrance 210 is flowed into fills up; and shown in figure 32; in the communication path 221 of the sinuous extension corresponding with the first 213a of elongated slot portion, be now positioned at the ink that the circuit portion 221a of below is flowed into and fill up.So due in this communication path 221, the circuit portion 221a below being arranged in cannot carry out gas-liquid exchange, therefore in the interior generation negative pressure of ink chamber 50, result, this negative pressure and water-head balance, ink stops to air chamber 200 side flow.
In addition, as shown in Figure 33 and Figure 35, when the ink tank 43 in inversion state has further been applied the vibration with the acceleration on fore-and-aft direction Y, as shown in Figure 34 and Figure 36, the ink in the communication path 221 shown in Figure 32 moves in the interior direction to applying acceleration of this communication path 221.But, in this case, ink in communication path 221 is only according to the direction of acceleration, to move back and forth between one distolateral (the first opening 211 sides) in this communication path 221 and another distolateral (the second opening 212 sides), can in the second air cell 200b as atmospheric air open port 60 sides, not flow out from the second opening 212.The length of the first 213a of elongated slot portion of this communication path 221 is set to than the distance between the first opening 211 and the second opening 212, and described the first 213a of elongated slot portion is along the part in the direction of spaced walls 48b.By the length of further growth the first 213a of elongated slot portion, can further suppress to arrive the second opening 212 because the vibration on fore-and-aft direction Y causes ink.
And, during attitude when the inverted attitude that is positioned at the upside of air chamber 200 when the ink chamber 50 shown in the attitude of ink tank 43 waits from Figure 31 is back to the air chamber 200 of Figure 13 shown in waiting and is positioned at the use of ink chamber's 500 upsides, the ink flowing in communication path 221 turns back to each air cell 200a, 200b from the first opening 211 and the second opening 212.Therefore, can avoid ink to remain in the communication path 221 that flow path cross sectional area is little and dry solidification.
Next, operation when choke valve 45 is switched to out to valve state from closing valve state is described.
In the present embodiment, as shown in figure 37, when choke valve 45 is when closing valve state, the groove 344 being formed on the handle part 341 of valve rod 47 is configured in the position bottom in the circular path centered by rotating shaft 331.
In this case, as shown in figure 38, the position, top of the raised line 317 of slide block 310 is configured in the valve position that closes with tabular surface 348 butts of the outer peripheral face of cam 345.And slide block 310 is pressed to the interior dark thruster of container unit 303 by the tabular surface 348 of cam 345.
Therefore the outer surface of pipe 31 of interior dark side that, is inserted through up and down container unit 303 is by the position, top of the 315a of pushing portion, the 315b of slide block 310 pushing and flatten.As a result, pipe 31 suppressed ink by the position of being flattened by the 315a of pushing portion, the 315b of slide block 310 from ink tank 43 side direction jet head liquid 32 side flow.
Then, as shown in figure 39, by valve rod 47 centered by rotating shaft 331 to the clockwise direction rotary manipulation shown in Figure 39.So the raised line 317 of slide block 310 is climbed up flexure plane 355 and is configured in centre position from the tabular surface of cam 345.
In this case, the rotational resistance of outer peripheral face that acts on cam 345 from slide block 310 is different under following two kinds of situations, situation is the raised line 317 of slide block 310 while climbing up flexure plane 355 from the tabular surface 348 of cam 345, and another kind of situation is that the raised line 317 of slide block 310 when slide on the flexure plane 355 of cam 345.Therefore, the resistance sense based on valve rod 47 is rotated to when operation to valve opening position changes, and can easily recognize that choke valve 45 starts to be switched to out valve state from closing valve state.
Then, as shown in figure 40, valve rod 47 is further rotated to operation to the clockwise direction shown in Figure 40 centered by rotating shaft 331.Now, the distance between the flexure plane 355 of cam 345 and the axle center J of rotating shaft 331 is along with little by little diminishing from tabular surface nearly protuberance 350 sides of 348 side joint.Therefore,, along with the rotation of cam 345, from the flexure plane 355 of cam 345, to the directive effect of flattening pipe 31, in the pushing force of slide block 310, reduce gradually.Now, slide block 310 is pushed back owing to managing 31 elastic restoring force with the position, top of the 315a of pushing portion of the outer surface butt of pipe 31.Therefore, the raised line 317 of slide block 310 maintains the state with flexure plane 355 sliding-contacts of cam 345 when cam 345 rotation.
Then, when valve rod 47 is further rotated to operation to the clockwise direction shown in Figure 40 centered by rotating shaft 331, the raised line 317 of slide block 310 is climbed up the protuberance 350 of cam 345.
So, as shown in Figure 21, Figure 22, the position, top of the raised line 317 of slide block 310 be configured in the outer peripheral face with cam 345, approach rotating shaft 331 most surface portion 356(with reference to Figure 22) butt drive valve position.That is, in the present embodiment, cam 345 has protuberance 350 in following surface portion, described surface portion slide block 310 from middle change in location when driving valve position and raised line 317 sliding-contacts of slide block 310.And, from the outer peripheral face of cam 345, to the directive effect that pushes pipe 31, in the pushing force of slide block 310, reduce gradually.As a result, pipe 31 is not flattened by the 315a of pushing portion of slide block 310 substantially.Therefore, choke valve 45 becomes permission ink from the valve state of opening of ink tank 43 side direction jet head liquid 32 side flow.
Here, when climbing up the protuberance 350 of cam 345, the raised line 317 of slide block 310 acts on the rotational resistance of outer peripheral face of cam 345 from slide block 310 larger when the flexure plane 355 of cam 345 slides than the raised line of slide block 310 317.Therefore, the resistance sense based on valve rod 47 is rotated to when operation to valve opening position changes, and can easily recognize that choke valve 45 has been switched to the valve state of opening.
In addition, when the raised line 317 of slide block 310 has been climbed up the protuberance 350 of cam 345, raised line 317 is sounded with the outer peripheral face collision of cam 345.Therefore, can easily recognize that valve rod 47 has been switched to the valve state of opening.
In addition, when choke valve 45 has been switched to while opening valve state, the protuberance 350 of cam 345 is by raised line 317 lockings of slide block 310, so choke valve 45 is fixed on out valve state for the time being.Therefore,, even valve rod 47 has been removed for the applying of the external force of rotary manipulation, also can choke valve 45 be maintained out to valve state with good reliability.
And, as shown in figure 20, when choke valve 45 is positioned at out valve state, be formed on the position that groove 344 on the handle part 341 of valve rod 47 is configured in the top in the circular path centered by rotating shaft 331.
Choke valve 45 is switched to while closing valve state too from opening valve state, and the raised line 317 of slide block 310 is climbed up the protuberance 350 of cam 345.But, when choke valve 45 is switched to out valve state from closing valve state, in protuberance 350, be concavity bending with the flexure plane 351 of raised line 317 sliding-contacts of slide block 310.On the other hand, when choke valve 45 is switched to while closing valve state from opening valve state, in protuberance 350, be convex curvature with the flexure plane 352 of raised line 317 sliding-contacts of slide block 310.
The rotational resistance acting on the outer peripheral face of cam 345 from slide block 310 while as a result, climbing up the protuberance 350 of cam 345 about the raised line 317 when slide block 310 has following relation: this rotational resistance when choke valve 45 is switched to out to valve state from closing valve state is greater than choke valve 45 is switched to this rotational resistance while closing valve state from opening valve state.Therefore,, when choke valve 45 is switched to out to valve state, the size that acts on the turning moment on cam 345 is relatively large.Therefore, the variable quantity of the resistance sense during due to cam 345 rotary manipulation is large, can recognize more easily that choke valve 45 has been switched to the valve state of opening.
Next, the operation of the ink tank 43 while being obliquely installed multifunctional equipment 11 is described.In addition, Fig. 4 and Fig. 5 illustrate the structure of ink tank 43.
In multifunctional equipment 11, when its installation surface tilt or at tank unit 27(with reference to Fig. 1) while being arranged on apparatus main body 13 under the state that tilts, ink tank 43 can become the state of inclination sometimes.
So when ink tank 43 becomes heeling condition and the step bottom surface 50b side that makes ink chamber 50 during higher than basal surface 50a side, ink is from step bottom surface 50b side direction basal surface 50a side flow.In this case, be contained in ink in ink chamber 50 concentrating on liquid collecting with after in recess 50d, by export mouth 59, flow out.
On the other hand, as shown in figure 41, when ink chamber 50 becomes heeling condition and the basal surface 50a side that makes ink chamber 50 during higher than step bottom surface 50b side, can suppress ink to step bottom surface 50b side flow by step side 50c.So because export mouth 59 is arranged on the basal surface 50a side (in Figure 41 for right-hand member side) on the length direction (fore-and-aft direction Y) of bottom, therefore by step side 50c interception, the ink in basal surface 50a side flows out from export mouth 59.
Now, if step bottom surface 50b and step side 50c are not set in ink tank 43, as shown in the double dot dash line in Figure 41, the ink of the bottom side having stockpiled at step-down can not flow out and can remain from export mouth 59.On the other hand, in the present embodiment, after step side 50c interception is in the ink of basal surface 50a side concentrates on liquid collecting use recess 50d, from export mouth 59, flow out.
As a result, stockpile at the ink of step bottom surface 50b side and can not flow out and remain from export mouth 59, but this surplus be few when step bottom surface 50b and step side 50c are not set.That is,, in ink tank 43, if become heeling condition to be provided with the first distolateral mode uprising export mouth 59, on length direction, the amount of ink that remains in the bottom of ink chamber 50 can tail off.
In addition, in tape deck 12, when by being arranged on housing container 48(with reference to Fig. 1) on Visual Confirmation face 43a(with reference to Fig. 1) Visual Confirmation has been when declined to the liquid level 51 in ink chamber 50, by supplementing ink from inlet 52 infusing inks.
But, if ink does not remain in the bottom of ink chamber 50 from export mouth 59 outflows, although can be from being arranged on the Visual Confirmation face 43a Visual Confirmation liquid level 51 housing container 48, likely cannot be by this ink feed to jet head liquid 32(with reference to Fig. 1).
So, may under the state by export mouth 59 supply inks, not spray ink, thereby it is bad that printing occurs.In addition, even add up to manage the ink surplus in ink chamber 50 by the emitted dose of the ink to from jet head liquid 32, if ink does not remain in the bottom of ink chamber 50 from export mouth 59 outflows, may there is same printing bad.About this point, in the present embodiment, owing to remaining in the amount of ink of the bottom of ink chamber 50, reduce, so this possibility is lowered.
In addition, in tape deck 12, owing to utilizing water-head to be contained in ink feed in ink chamber 50 to jet head liquid 32, therefore ink tank 43 is formed to width on fore-and-aft direction Y increases and above-below direction Z on the shape of growing crosswise that reduces of height.Therefore, in Dang Xiang ink chamber 50, during infusing ink, the ink splashing in the bottom of ink chamber 50 etc. may overflow from inlet 52.About this point, in the present embodiment, because inlet 52 is configured in the top being positioned at than the basal surface 50a of 50bDi position, step bottom surface, so ink is difficult to overflow from inlet 52.
Next, the operation when being contained in ink in ink chamber 50 and deriving from export mouth 59 is described.
As mentioned above, although the ink being contained in ink chamber 50 is stirred when infusing ink, the deviation of concentration reduces, and along with the process of time, pigment composition can precipitate sometimes, and the concentration of ink can produce deviation.That is, be positioned at the concentration meeting retrogradation (following, to be called " thick ink ") of the ink of below, be positioned at the concentration meeting thinning (following, to be called " rare ink ") of the ink of top.
Therefore, when the liquid level 51 of ink is positioned at than the high position of the first intersection flank 101, rare ink by the first interconnecting part 106 intersecting between flank 101 and end face 50e to export mouth 59 side flow.On the other hand, the interconnecting part 105 of lower end of thick ink by being positioned at the first intersection flank 101 is to export mouth 59 side flow.Therefore under the state that, ink mixes with rare ink at thick ink, from export mouth 59, derive.
And when ink is derived, the change in location of liquid level 51 is when than low position, the upper end of the first intersection flank 101, rare ink intersects between flank 102 and end face 50e to export mouth 59 side flow by second.On the other hand, the interconnecting part 105 of lower end of thick ink by being positioned at the second intersection flank 102 is to export mouth 59 side flow.And ink is derived from export mouth 59 by the first interconnecting part 105 that intersects flank 101 under the state of thick ink and the mixing of rare ink.
And, when ink is derived, the change in location of liquid level 51 when than low position, the upper end of the second intersection flank 102, rare ink by the 3rd interconnecting part 106 intersecting between flank 103 and end face 50e to export mouth 59 side flow.On the other hand, thick ink intersects the interconnecting part 105 of lower end of flank 103 to export mouth 59 side flow by being positioned at the 3rd.That is, ink is derived from export mouth 59 by the interconnecting part 105 of the second intersection flank 102 and the interconnecting part 105 of the first intersection flank 101 under the state of thick ink and the mixing of rare ink.
According to above-mentioned the first embodiment, can obtain following effect.
(1) when for film 49 being arranged on the housing peristome 48a of housing container 48, while for example keeping the film 49 by keeping utensil to keep and moving, such as using the through hole 49H that can insert the positioning elements such as pin, can be easily with respect to keeping utensil to position.Therefore, after film 49 being transported to the position of housing peristome 48a of sealing housing container 48 not produce the predetermined state of dislocation, such as installing with respect to housing container 48 by welding etc.Therefore, can suppress to seal the film 49 that the mode of the housing peristome 48a of housing container 48 is arranged on housing container 48 misplaces with respect to housing peristome 48a.
(2) even if film 49 is for having the shape of the length direction of relatively easy generation dislocation, owing to can utilizing the through hole 49H of at least two positions that are separated from each other on this length direction to carry out orientation film 49, the film 49 that therefore can suppress to be arranged on housing container 48 misplaces with respect to housing peristome 48a.
(3) in ink tank 43, because the region exterior position 49a of the film 49 that the housing peristome 48a from housing container 48 can be exposed laterally, 49b, 49c, 49d take in by folding put into etc., so that its be not exposed to and can container 42 between gap in, therefore for example can obtain the tank unit 27 of good appearance.
(4) owing to can suppressing to be arranged on the dislocation with respect to housing peristome 48a of film 49 on housing container 48, therefore can realize the tape deck 12(liquid consuming device with following tank unit 27), described tank unit 27 has the good ink chamber of closure 50.
(5) because the ink chamber 50 from tank unit 27 supplies inks via pipe 31 to jet head liquid 32, therefore for example can realize the tape deck 12(liquid consuming device that a large amount of inks is supplied to constantly to jet head liquid 32).
(6) owing to film 49 being installed to housing container 48, can suppress film 49 misplaces with respect to housing peristome 48a, therefore for example can suppress due to and housing container 48 between the decline of the power that is adjacent to that causes of the minimizing of welding area, thereby can obtain the good seal of ink tank 43.
(7) due to ink chamber 50 in step bottom surface 50b separate and be provided with vertical flank 111-118, therefore from inlet 52, be injected into ink ink chamber 50 with mobile between this step bottom surface 50b and vertical flank 111-118 along the mobile mode of step bottom surface 50b.And when the trailing flank 50g is intersected by the step bottom surface 50b with vertical flank 111-118, ink chamber 50 when flowing of ink etc. has hindered, ink produces mobile in the direction of intersecting with step bottom surface 50b.Therefore, even if the ink being contained in ink chamber 50 has produced concentration deviation, also can be by being newly injected into the mobile ink being contained in ink chamber 50 that stirs of the ink in ink chamber 50.That is, even on fore-and-aft direction Y away from the position of inlet 52, also can produce flowing upward.Therefore,, by infusing ink in ink chamber 50, can easily eliminate the concentration deviation of the ink being contained in ink chamber 50.
(8) ink injecting from inlet 52 is derived from export mouth 59.Therefore, being positioned at the position of a side contrary with export mouth 59 when inlet 52 is observed, compare with the position between export mouth 59 with inlet 52, be difficult to along with deriving ink and produce flowing of ink from export mouth 59.About this point, owing to being positioned at a side contrary with export mouth 59 when from inlet 52 observation, be provided with vertical flank 111-118, therefore can be along with stirring and be positioned at the ink that is difficult to produce along with derivation the mobile position of ink from inlet 52 infusing inks.Therefore,, by the interior infusing ink of ink chamber 50, can eliminate efficiently the concentration deviation of the ink being contained in ink chamber 50.
(9) by outstanding formation of the right flank 50f in ink chamber 50, indulge flank 111-118, can easily form vertical flank 111-118.And, by forming at least two vertical flank 111-118, can increase the region that can stir, therefore can make the size of ink chamber 50 larger.
(10) by the upwardly extending vertical flank 111-118 in side intersecting with step bottom surface 50b, can make ink along leave inlet 52 direction, be that fore-and-aft direction Y is mobile.That is,, by making ink produce vortex-like flowing, can stir ink.
(11) because intersection flank 101-103 is arranged between inlet 52 and export mouth 59, therefore can hinder ink and flow to export mouth 59 from inlet 52.Therefore,, even for example from inlet 52 infusing ink in large quantities or rapidly, also can reduce to be applied to the pressure near ink export mouth 59.
(12) when having derived by export mouth 59 ink being contained in ink chamber 50, ink can produce by the flowing of interconnecting part 105,106, and described interconnecting part 105,106 is positioned at different positions on above-below direction Z.Therefore,, even if the ink being contained in ink chamber 50 has produced concentration deviation, also can make the ink of variable concentrations flow by each interconnecting part 105,106.And because the position of interconnecting part 105,106 is different, therefore at least two intersection flank 101-103 can make the ink that is positioned at diverse location on above-below direction Z flow.Therefore, even if the ink being contained in ink chamber 50 is exported, liquid level 51 has declined, and also can make near near the rare liquid of the concentration of the liquid level 51 thick liquid of concentration with basal surface 50a mix and derive.
(13) by increase, be positioned at and leave locational first of inlet 52 and intersect flank 101 from the outstanding height of basal surface 50a, can further hinder ink and flow to export mouth 59 from inlet 52.On the other hand, owing to being positioned at, approaching locational second of inlet 52 to intersect flank 102 little from the outstanding height of basal surface 50a, therefore allow to be highlighted the first highly large ink that intersects flank 101 interceptions and flow to the rear of leaving export mouth 59.Therefore,, leave a side of export mouth 59 when inlet 52 is observed, can further stir ink.
(14) because intersection flank 101-103 has the first extension 104, the ink that therefore can reduce to inject from inlet 52 is crossed the possibility of intersection flank 101-103.Therefore, can further reduce the pressure being applied near the ink of export mouth 59.
(15) can use following tape deck 12, described tape deck 12 can easily be eliminated the concentration deviation of the ink being contained in ink chamber 50.
(16) under the attitude when the use of ink tank 43, air chamber 200 is positioned at the top of ink chamber 50, and ink is difficult to by connected entrance 210, enter into air chamber 200 sides from ink chamber's 50 sides, and therefore can suppress ink leaks into outside by atmospheric air open port 60.
(17) in addition,, even the attitude when using is inverted by ink tank 43, because the ink in ink chamber 50 can temporarily enter in the inner space of air chamber 200 by connected entrance 210, therefore can suppresses ink and directly leak out from ink chamber 50.Therefore,, even in the situation that being inverted, also can suppressing to be contained in inner ink and leak into outside by atmospheric air open port 60.
(18) even if ink has flow in an air cell 200a who is communicated with by connected entrance 210 from ink chamber 50, owing to need to just flowing in the next air cell 200b being communicated with this air cell 200a by thering is the communication path 221 of little flow path cross sectional area, therefore can suppress ink to the air cell 200j side flow that is formed with atmospheric air open port 60.Therefore, can further suppress to be contained in inner ink and leak into outside by atmospheric air open port 60.
(19) Dang Cong ink chamber 50 side inflows to the ink in the first air cell 200a will be further when the first air cell 200a flow to the second air cell 200b, ink need to flow to the second opening 212 from the first opening 211 in communication path 221, and described communication path 221 has than the distance of the distance between the first air cell 200a and the second air cell 200b.Therefore,, because the distance of this length has increased the flow path resistance for the ink from the first air cell 200a to the second air cell 200b side flow, therefore can further suppress to be contained in inner ink leaks into outside by atmospheric air open port 60.
(20) though ink because ink tank 43 is inverted Er Cong ink chamber 50 side inflows to air chamber 200 sides and further flow in the communication path 221 of connection the first air cell 200a and the second air cell 200b, when revert to while using attitude time, the ink in communication path 221 can be by the first opening 211 and the second opening 212 from the interior outflow of communication path 221.Therefore, can avoid because ink remains in communication path 221 and dry causing at the interior generation solidfied material of communication path 221.
(21) even be inverted ink tank 43 under near state gas-liquid interface arrives the first opening 211, the communication path 221 that connects this first opening 211 and the second opening 212 also has circuit portion 221a, this circuit portion 221a due to than the first opening 211 and the second opening 212 more away from spaced walls 48b, therefore away from gas-liquid cross section.Therefore,, even in the situation that being inverted, at the circuit portion 221a place that becomes the position of lower side, also can make air and ink cannot carry out gas-liquid exchange.Therefore, can make to produce negative pressure than the part of the more close ink chamber of communication path 221 50 sides, thereby can make ink stop leaking from ink chamber's 50 sides.
(22) owing to becoming the mode junction film 214 of the opening of the 213a-213c of elongated slot portion that wriggle to extend shape with enclosed shape, form communication path 221,223,225, therefore can realize simply following communication path 221,223,225, described communication path 221,223,225, in the inverted situation of ink tank 43, can have been given play to rightly and can suppress the effect that ink leaks from ink chamber 50.
(23), when making slide block 310 change in location when driving valve position, because slide block 310 need to be crossed the protuberance 350 of cam 345, the torque that therefore acts on cam 345 increases.Therefore,, when slide block 310 is along with cam 345 is rotated while changing to out valve position according to manual operation, resistance sense when cam 345 is rotated to operation changes.Therefore, can easily recognize the slide block 310 that occurrence positions changes in order to switch the circulation status of ink, according to having changed to and driven valve position according to manual operation.
(24) when along with make cam 345 rotation make slide block 310 from driving valve position when closing valve position and change by manual operation, and when making slide block 310 from closing valve position when driving valve position and change, the protuberance 350 of crossing cam 345 due to slide block 310 acts on the varying in size of torque of cam 345.Therefore, can easily recognize cam 345 is in order to make slide block 310 to which direction of driving valve position and close in valve position change and rotate.
(25), when making cam 345 rotation make slide block 310 change to out valve position by manual operation, the size of torque that acts on cam 345 in order to make the flexure plane 351 of protuberance 350 cross slide block 310 is relatively large.Therefore, when slide block 310 changes to out valve position, the variable quantity of resistance sense that cam 345 is rotated to when operation is larger, therefore can recognize more easily that slide block 310 has changed to drive valve position.
(26), when making slide block 310 change to centre position from closing valve position, cam 345 is from being switched to the state with slide block 310 butts by flexure plane 355 by tabular surface 348 and the state of slide block 310 butts.Therefore,, when making slide block 310 change to centre position from closing valve position, the torque that acts on cam 345 changes.Therefore, the variation of the resistance sense while operating by cam 345 is rotated, can easily recognize that slide block 310 has changed to centre position from closing valve position.
(27), because choke valve 45 is arranged on the medial surface of can container 42, even if therefore applied impact from the outside of can container 42 to choke valve 45, also can suppress this impact and be delivered to ink tank 43 from choke valve 45.In addition, because choke valve 45 is arranged on the medial surface of can container 42, therefore can prevent that vibration that the opening and closing operations due to valve produces etc. is directly delivered to ink tank 43, thereby can prevent the generation that the vibration due to ink tank 43 causes the liquid level of ink to vibrate and produce the unfavorable conditions such as bubble.In addition, from choke valve 45 is arranged on to the inner bottom surface of can container 42 on time different, because needs are used in, choke valve 45 is fixed by screws in to support 361 on the inner bottom surface of can container 42 thickness direction from choke valve 45 to can container 42 extends, therefore can reduce the size on the thickness direction of can container 42.In addition, owing to choke valve 45 and ink tank 43 can being assembled in can container 42 independently, therefore can improve choke valve 45 with respect to the assembleability of can container 42.
(28), in ink tank 43, when ink chamber 50 has become step bottom surface 50b side higher than the heeling condition of basal surface 50a side, can make ink flow out from step bottom surface 50b side direction basal surface 50a side flow and from export mouth 59.On the other hand, when ink chamber 50 has become basal surface 50a side higher than the heeling condition of step bottom surface 50b side, can suppress ink to step bottom surface 50b side flow by step side 50c.And, because export mouth 59 is arranged on the position of basal surface 50a side on the length direction (fore-and-aft direction Y) of bottom, therefore can make the ink in basal surface 50a side by step side 50c interception flow out from export mouth 59.That is, can avoid in the situation that ink tank 43 has become heeling condition, the ink in ink chamber 50 all do not flow out and remain in bottom.Therefore,, even in the situation that having become heeling condition, also can reduce the amount of the ink of the bottom that remains in ink chamber 50.
(29) choke valve 45 is arranged between front surface 43b and can container 42, described front surface 43b form ink tank 43 except bottom surface 43c and side the end face 43d relative with this bottom surface 43c.Therefore, compare with the situation between can container 42 with the bottom surface 43c or the end face 43d that choke valve 45 are configured in to ink tank 43, can suppress the height of tank unit 27.
(30) choke valve 45 is configured between front surface 43b and can container 42, described front surface 43b be ink tank 43 except bottom surface 43c and the narrowest surface of width in side the end face 43d relative with this bottom surface 43c.Therefore,, owing to choke valve 45 can being accommodated in the scope of width of the narrowest front surface 43b of width in the side of ink tank 43, the width that therefore can suppress tank unit 27 maximizes.
(31) in ink tank 43, because the Length Ratio step bottom surface 50b on the fore-and-aft direction Y of basal surface 50a is short, therefore in the situation that basal surface 50a has become heeling condition, can reduce not from export mouth 59 and flow out and the amount of residual ink, described export mouth 59 is arranged on the end side on the fore-and-aft direction Y of basal surface 50a.
(32) in ink tank 43, when ink chamber 50 has become the first distolateral heeling condition uprising on length direction, because step side 50c is near the first distolateral configuration, therefore it is higher that the upper end position of step side 50c just becomes, and can be arranged near the high liquid level position of maintenance the first distolateral export mouth 59.Therefore,, even in the situation that the angle of inclination of ink chamber 50 becomes large, also can make the ink in basal surface 50a side by step side 50c interception flow out from export mouth 59.
(33), in ink tank 43, the ink of being tackled in basal surface 50a side can be concentrated in liquid collecting use recess 50d, and by export mouth 59, ink is flowed out by step side 50c.Therefore, the bottom in ink chamber 50, can reduce the amount that remains in the ink of basal surface 50a side due to step side 50c.
(34), in ink tank 43, because inlet 52 is configured in the top being positioned at than the basal surface 50a of 50bDi position, step bottom surface, therefore, when infusing ink, ink is difficult to overflow.
Therefore (35), in ink tank 43, because basal surface 50a tilts in the mode of export mouth 59 side step-downs, can make by step side 50c interception at the ink of basal surface 50a side along inclined-plane to export mouth 59 side flow.Therefore,, even in the situation that having become heeling condition, also can reduce the amount of the ink of the bottom that remains in ink chamber 50.
(the second embodiment)
Next, with reference to accompanying drawing, the second embodiment of the present utility model is described.In addition, this second embodiment do not have in scanner unit 14 this point different from the first embodiment.In addition, due to roughly the same with the first embodiment in other respects, therefore identical structure is marked to identical label, the repetitive description thereof will be omitted thus.
As shown in figure 42, the tape deck 85 as an example of liquid consuming device has action button 86 in front surface side.In tape deck 85, in the position being positioned at below action button 86, be provided with for discharge the outlet 88 of paper P from apparatus main body 87.In addition, below the outlet 88 in tape deck 12, accommodate the ADF platform 89 that can extract out.And, in the rear side of tape deck 85, the dielectric support body 90 of the rotary type that can load multiple paper P is installed.
In addition, as shown in Figure 42, Figure 43, in apparatus main body 87, in the forward position that the installed surface 87a of tank unit 27 is installed, be formed with the extension 87b that is wedge-like while overlooking.In addition, extension 87b forwards forms from top agley in the mode in the gap between landfill apparatus main body 87 and tank unit 27, and the front surface of the front surface of extension 87b and tank unit 27 forms same plane.
And as shown in figure 44, tank unit 27 is fixed on apparatus main body 87 by distance piece 91, the gap of the lower portion of described distance piece 91 landfill tank unit 27 and apparatus main body 87, and cross section is L word shape.In addition, distance piece 91 is set to the cooperating recesses 72 corresponding with the 4th container lock bonding part 68d from extension 87b on fore-and-aft direction Y.And distance piece 91 coordinates with the cooperating recesses 72 that is formed with the 4th container lock bonding part 68d.
Next, operation when tank unit 27 is arranged on tape deck 85 is described.
As shown in figure 44, first by the can container 42 that is fixed with ink tank 43 under the state across distance piece 91 with installed surface 87a contraposition.In addition, now, the not shown auxiliary section of distance piece 91 coordinates with boss portion 38, and coordinates contraposition thus with the cooperating recesses 72 that is formed with the 4th container lock bonding part 68d.
Then, under the state of can container 42 and installed surface 87a contraposition, screw 36 and container lock bonding part 68a-68e are screwed togather, thereby can container 42 is fixedly connected with apparatus main body 87.
Then, in can container 42, be fixedly connected under the state on apparatus main body 87 the mode mounting cover 44 coordinating with sliding contacting part 80 with rail portion 76a, 76b from the rear of can container 42.
According to above-mentioned the second embodiment, can obtain the effect identical with above-mentioned the first embodiment.
(the 3rd embodiment)
Next, with reference to accompanying drawing, the 3rd embodiment of the present utility model is described.In addition, the shape of the housing container 125 of the 3rd embodiment is different from the first embodiment.In addition, because other aspects are basic identical with the first embodiment, even the therefore structure of the inside of housing container 125, also the repetitive description thereof will be omitted also same component part to be marked to same label.
As shown in figure 45, housing container 125 form there is housing peristome 125a have a under casing shape.And, on housing container 125, at least one (being in the present embodiment two) tank sticking department 126 of locking mounting screw 61 is formed on the downside of housing container 125, and described mounting screw 61 was mounted when upper being fixed on can container (omit diagram).On the other hand, in not shown can container, on the position corresponding with tank sticking department 126, be formed with the screw part (omitting diagram) that can screw togather with mounting screw 61.
As shown in Figure 45-Figure 47, in ink chamber 50, be formed with at least two (being in the present embodiment six) as the 131-136 of cross rib portion of an example of first rib.The 131-136 of cross rib portion extends towards the direction along step bottom surface 50b.The 131-136 of cross rib portion extends along fore-and-aft direction Y and left and right directions X, and the 131-136 of cross rib portion is arranged on the position of a side contrary with export mouth 59 when from inlet 52 observation on fore-and-aft direction Y.
In addition, the 131-136 of cross rib portion has compartment of terrain and forms at least one row (being two row in the present embodiment) on above-below direction Z.And, the 131-136 of cross rib portion on gravity direction between inlet and step bottom surface 50b.In addition, the cross rib portion that forms each row (being in the present embodiment three) mutually has interval on fore-and-aft direction Y, and also has interval at the trailing flank 50g of fore-and-aft direction Y Shang Yu ink chamber 50.That is, the first cross rib portion 131 to the 3rd cross rib portion 133 has interval on fore-and-aft direction Y, and the 4th cross rib portion 134 to the 6th cross rib portion 136 compares with the first cross rib portion 131 to the 3rd cross rib portion 133 and is positioned at top, and on fore-and-aft direction Y, mutually has interval.
That is, the 131-136 of cross rib portion and step bottom surface 50b and spaced walls 125b have gap, therefore the side of being located thereon with step bottom surface 50b partition distance.In addition, both sides up and down at the 131-136 of each cross rib portion, be formed with three extension 137 vertical with right flank 50f, described the 3rd extension 137 along with the mode that the housing peristome 125a side joint nearly right flank 50f side (right side) from housing container 125 broadens gradually, is approximate right angle triangular shaped with the width on fore-and-aft direction Y in front view.
And the 131-136 of cross rib portion is vertical with the right flank 50f with housing container 125 with the 3rd extension 137, and one-body molded from right flank 50f side direction housing peristome 125a side-prominent mode and housing container 125.In other words, the 131-136 of cross rib portion and the 3rd extension 137 form from right flank 50f is outstanding.
And on left and right directions X, the width of the 131-136 of cross rib portion and width from the right flank 50f of housing container 125 to housing peristome 125a are about equally.Therefore,, when having engaged film 49 on housing peristome 125a, film 49 is also bonded on the composition surface 131a-136a of left end of the 131-136 of cross rib portion.
Next, the operation in the ink chamber 50 that is injected into ink is described.
As shown in figure 45, the ink injecting from inlet 52 is rearward to flow along the mobile mode of step bottom surface 50b.Therefore, when the liquid level in ink chamber 50 (omitting diagram) rises along with the injection of ink and has arrived the position that is formed with the 131-136 of cross rib portion, the downside of ink by the 131-136 of cross rib portion be rearward to flow and changes into the flowing upward along trailing flank 50g, and described trailing flank 50g intersects with the flow direction of ink.And ink forwards flows by being positioned at the upside of the first 131-the 3rd cross rib portion 133 of cross rib portion of downside.
Therefore, in ink chamber 50, hinder mobile situation and compare with being formed with vertical flank 111-118, ink is with flow rate faster.Therefore, for example, in the situation that ink being divided to injection several times, the ink that the ink first injecting is injected afterwards promotes and flows.That is, due to from the new infusing ink of inlet 52, the ink remaining in ink chamber 50 is stirred, even if the ink therefore in ink chamber 50 has produced concentration deviation, also can reduce the deviation of body.
And, when having injected ink, when the liquid level 51 of ink is positioned at upside, except the flowing of the liquid of the upside by the first 131-the 3rd cross rib portion 133 of cross rib portion, also can produce flowing of upside by the 4th 134-the 6th cross rib portion 136 of cross rib portion
According to above-mentioned the 3rd embodiment, can obtain following effect.
(34), by the upwardly extending cross rib 131-136 of portion in the side along step bottom surface 50b, after the flow direction of the mobile ink of step bottom surface 50b is changed into the top intersecting with step bottom surface 50b, can make ink flow along the 131-136 of cross rib portion.Therefore,, owing to can suppressing the mobile collision of ink, therefore can improve the flow velocity of ink mobile in the direction along step bottom surface 50b.
In addition, above-mentioned each embodiment also can change as follows.
In above-mentioned each embodiment, also can not arrange and will be contained in ink feed in the ink chamber 50 of tank unit 27 pipe 31 to jet head liquid 32.For example, also tank unit 27 can be configured on bracket 29.
In above-mentioned each embodiment, between ink tank 43 and can container 42, also can not arrange and can hold region exterior position 49a, 49b, the 49c of film 49, the gap of 49d.For example, if the width that the region exterior position 49a of film 49,49b, 49c, 49d expose from housing peristome 48a is narrow and can not cause apparent problem, between ink tank 43 and can container 42 without the need for gap.
In above-mentioned each embodiment, through hole 49H also can not be arranged on two positions of film 49 spaced apart from each other on the length direction of housing peristome 48a.For example, also can be arranged on two positions of film 49 spaced apart from each other on the width of housing peristome 48a.For example, and through hole 49H also can be arranged on the position of two above (three).
In above-mentioned each embodiment, through hole 49H also can only be arranged on a position in region exterior position 49a, 49b, 49c, 49d.In addition, the shape of through hole 49H is such as being rectangular openings such as quadrangle except circular hole etc.Or, can be also mutually different shape and size.In a word, can be any shape that can locate.
In above-mentioned each embodiment, as shown in figure 48, in ink chamber 50, also can form first 141(of diagonal rib portion the first variation tilting with respect to step bottom surface 50b).That is, the first diagonal rib portion 141 extends upward in the side along left and right directions X, and the mode that is positioned at the front side of lower end with upper end tilts with respect to above-below direction Z.In addition, the first diagonal rib portion 141 is provided with at least one or at least two (in Figure 48, being six), spaced apart with step bottom surface 50b and spaced walls 48b, and on fore-and-aft direction Y, mutually has interval.In addition, the trailing flank 50g of the first diagonal rib Bu141Yu ink chamber 50 also has interval on fore-and-aft direction Y.
In above-mentioned each embodiment, as shown in figure 49, in ink chamber 50, also can form second 142(of diagonal rib portion the second variation tilting with respect to step bottom surface 50b).That is, the second diagonal rib portion 142 extends upward in the side along left and right directions X, and the mode that is positioned at front side, upper end with lower end tilts with respect to above-below direction Z.In addition, the second diagonal rib portion 142 is provided with at least one or at least two (in Figure 49, being six), spaced apart with step bottom surface 50b and spaced walls 48b, and on fore-and-aft direction Y, mutually has interval.In addition, the trailing flank 50g of the second diagonal rib Bu142Yu ink chamber 50 also has interval on fore-and-aft direction Y.
In above-mentioned each embodiment, as shown in figure 50, first vertical flank the 111, second vertical flank 112, the second cross rib portion 132, the 3rd cross rib portion 133, the 5th cross rib portion 135, the 6th 136(of cross rib portion the 3rd variation also can be set in ink chamber 50).That is, also can at random combine, arrange vertical flank 111-118, the 131-136 of cross rib portion.In addition, also can at random select the quantity of vertical flank 111-118, the 131-136 of cross rib portion.That is, for example also can be arranged on rear side by indulging flank, and cross rib portion is arranged on to front side.In addition, on fore-and-aft direction Y, vertical flank and cross rib portion also can alternatively arrange.
In above-mentioned each embodiment, as shown in Figure 51, also can make the size different (the 4th variation) of the Z along the vertical direction of vertical flank 111-118.; for example also the size on the above-below direction Z of vertical flank 111-118 can be set as: be positioned at the first vertical flank 111 maximums of the position (front side) that approaches inlet 52, from this first vertical flank 111, to the 8th vertical flank 118 being positioned at away from the position (rear side) of inlet 52, reduce gradually.And the size on the above-below direction Z of vertical flank 111-118 is less, arranges away from step bottom surface 50b.
Be positioned at vertical flank 111-118 away from the position of inlet 52 owing to having very large interval with step bottom surface 50, therefore can produce vortex in the position away from step bottom surface 50b.Therefore, in the position of leaving the concentration deviation inlet 52 that easily change is large of ink, can stir near the thick ink of the concentration of step bottom surface 50b and near the rare ink of concentration liquid level 51, therefore can further reduce the concentration deviation of ink.
In above-mentioned each embodiment, as shown in Figure 52, also can make the interval different (the 5th variation) between vertical flank 111-117 adjacent on fore-and-aft direction Y.That is, vertical flank 111-117 is set to: the first vertical flank 111 and the interval between the second vertical flank 112 in front side are minimum, is positioned at the vertical flank of rear side, and its interval is larger.That is,, about the interval of vertical flank adjacent on fore-and-aft direction Y, the interval between the vertical flank of front side is less than the interval between the vertical flank at rear side.In addition, if the quantity of vertical flank is more than or equal to 3, can at random select.
Between vertical flank 111-117, produce vortex-like the flowing that is hindered by vertical flank 111-117 and produce along with flowing, described vertical flank 111-117 is adjacent on the fore-and-aft direction Y as ink flow direction.And the interval between vertical flank 111-117 is larger, can produce larger vortex-like flowing.About this point, because the interval between vertical flank 111-117 adjacent on the position away from inlet 52 is large, therefore in the position away from inlet 52, can produce larger vortex-like flowing.Therefore,, in the position of the inlet 52 that easily change is large of the concentration deviation away from ink, the ink rare due near concentration liquid level 51 also flows in this position, therefore can further reduce the concentration deviation of ink.
In above-mentioned each embodiment, as shown in Figure 53, the face of front side that also can protuberance 121,122 is set to intersect as follows with step bottom surface 50b: to the rear away from inlet 52, form acute angle (the 6th variation).The face of rear side that in addition, also can protuberance 121,122 is set to intersect as follows with step bottom surface 50b: to the place ahead that approaches inlet 52 sides, form acute angle.
The ink injecting from inlet 52 flows along step bottom surface 50b.And the face of the front side of protuberance 121 intersects as follows with step bottom surface 50b: form acute angle to the rear as ink flow direction.That is, because flow path resistance reduces, therefore can be when guaranteeing the rigidity of ink tank 43, the ink that makes to be injected in ink chamber 50 flows well to the rear away from inlet 52.In addition, because the face of the rear side of protuberance 121 intersects with step bottom surface 50b in the acutangulate mode of shape forwards, therefore can further reduce flow path resistance.
In above-mentioned each embodiment, as shown in Figure 53, in the situation that protuberance 21 is set, also can not be arranged on the vertical flank that is positioned at the position that approaches the first protuberance 121 on fore-and-aft direction Y.That is, for example also can be at interior the first vertical flank 111, the 4th vertical flank 114, the 7th vertical flank 117, the 8th vertical flank 118 of arranging of ink chamber 50.In this case, on fore-and-aft direction Y, across the first vertical flank 111 of the first protuberance 121 configurations and the interval between the interval between the 4th vertical flank 114 and the 4th vertical flank 114 and the 7th vertical flank 117, be greater than other the 7th vertical flank 117 and the interval of the 8th vertical flank 118.
By increasing the interval between the vertical flank of protuberance 121 configurations, can reduce the possibility of the vertical flank obstruction of mobile quilt of flow direction altered ink due to protuberance 121.That is, compare with the interval reducing between the vertical flank of protuberance 121 configurations, can reduce to the mobile flow path resistance in the rear away from inlet 52.Therefore, can guarantee the rigidity of ink tank 43, and the ink that can make to be injected in ink chamber 50 flows well to the direction away from inlet 52.
In above-mentioned each embodiment, also can at random change the height of intersection flank 101-103.For example, as shown in Figure 54, in intersection flank 101-103, be positioned at the intersection flank of front side, the height outstanding from basal surface 50a less (the 7th variation).That is, also can make the projecting height of the second intersection flank 102 larger than the projecting height of the first intersection flank 101, and less than the projecting height of the 3rd intersection flank 103.
In addition, also can as shown in Figure 55, make the projecting height of the first intersection flank 101 less than the projecting height of the second intersection flank 102, and than the projecting height large (the 8th variation) of the 3rd intersection flank 103.
Even in the situation that changed the height of intersection flank 101-103, the ink being contained in ink chamber 50 also can pass through according to the height of liquid level 51 interconnecting part 105 and 106 of each intersection flank 101-103.Therefore, even in the situation that change has occurred liquid level, also can make the ink that is positioned at diverse location on above-below direction Z pass through.
In above-mentioned each embodiment, also protuberance 121,122 can be set.In addition, protuberance 121 is arranged on basal surface 50a or step bottom surface 50b is upper, if outstanding from basal surface 50a or step bottom surface 50b, no matter be along what direction to extend, can both improve the rigidity of ink tank 43.That is, for example also can form protuberance 121 along fore-and-aft direction Y and above-below direction Z.In addition, also can be formed obliquely protuberance 121 with respect to above-below direction Z.
In above-mentioned each embodiment, the first extension 104, the second extension 119, the 3rd extension 137 also can be set.
In above-mentioned each embodiment, also intersection flank 101-103 can be formed to bending or bended.In addition, in this case, preferably intersect rearward bending of flank 101-103 or warpage.By making to intersect the upper end of flank 101-103, be positioned at the rear side of lower end, the ink that can reduce to inject from inlet 52 is crossed and is intersected the possibility of flank 101-103, and flowing of ink guided to rear side.
In above-mentioned each embodiment, also can make the 101-103 of diagonal ribs portion identical from the outstanding height of basal surface 50a.
In above-mentioned each embodiment, also can make the 101-103 of diagonal ribs portion and the spaced apart setting of basal surface 50a.That is, also can on fore-and-aft direction Y, be arranged between inlet 52 and export mouth 59 indulging flank 111-118.
In above-mentioned each embodiment, an intersection flank 101-103 also can be set.In addition, in the situation that an intersection flank 101-103 is set, the first intersection flank 101 that is positioned at the position that approaches export mouth 59 is preferably set.In addition, the first flank 101 and the second flank 102 also can not arrange the second interconnecting part 106.That is, also can make the first intersection flank 101 and second intersect flank 102 from the outstanding formation of end face 50e.Outstanding from end face 50e by making the first intersection flank 101 and second intersect flank 102, the ink that can further reduce to inject from inlet 52 is crossed the first intersection flank 101 and second and is intersected the possibility that flank 102 goes out to export mouth 59 effluents.And the second interconnecting part 106 also can be separately positioned on end face 50e and first and intersect between flank 101 and end face 50e intersects between flank 102 with second.By the second interconnecting part 106 is arranged on to end face 50e side, the position of the liquid level 51 that can make ink on above-below direction is in first area with consistent in second area, and described first area and second area are intersected flank 102 by the first intersection flank 101 and second to be separated.
In above-mentioned each embodiment, also can similarly by being recessed to form, intersecting the composition surface 101a-103a of flank 101-103 the second interconnecting part 106 is set with the first interconnecting part 105.In addition, also can similarly in ink chamber 50, spread all over right and left with the second interconnecting part 106 the first interconnecting part 105 is always set.
In above-mentioned each embodiment, vertical flank 111-118 also can be outstanding from spaced walls 48b.In addition, intersecting flank 101-103 also can be outstanding from the end face 50e of ink chamber 50.In addition, in this case, preferably in by vertical flank 111-118 and the intersection isolated region of flank 101-103, form the interconnecting part that air can back and forth pass through.
In above-mentioned each embodiment, intersection flank 101-103 also can be set.
In above-mentioned each embodiment, also can on fore-and-aft direction Y, two vertical flanks be set partition distance, and two vertical flanks are arranged on the upper different position of above-below direction Z.That is, for example also can make the measure-alike vertical flank on above-below direction different from the spacing distance between basal surface 50a.
In the above-described 3rd embodiment, a row cross rib 131-136 of portion also can be set.In addition, the 131-136 of cross rib portion of same row can be also a cross rib portion continuous on fore-and-aft direction.In addition, the 111-118 of cross rib portion also can only arrange one.
In above-mentioned each embodiment, vertical flank 111-118 or the 131-136 of cross rib portion also can be fixedly connected on the right flank 50f of housing container 48,125 by engage or cooperation etc.In addition, vertical flank 111-118 or the 131-136 of cross rib portion also can be set on film 49.
In above-mentioned each embodiment, the first opening 211 and the second opening 212 also can be respectively formed at for example, in the surface portion of interior dark side separately of adjacent two air cells (the first air cell 200a and the second air cell 200b), sow discord near next door 48b end face farthest.; also can the 9th variation shown in Figure 56; be formed near each position at for example, the turning wall of for example, spaced walls (the first spaced walls 201) between two air cells (the first air cell 200a and the second air cell 200b), and be formed on and take each position that this spaced walls 201 is the linear symmetry of benchmark.
In addition, in this case, the elongated slot portion on the lateral surface of sidewall 48c of housing container 48 of being formed on also can form the 230a-230c of elongated slot portion of linearity as shown in Figure 57.Even in the situation that form such structure, if ink tank 43 is inverted, as shown in Figure 58, in air chamber 200 sides, the ink that the first air cell 200a being directly communicated with ink chamber 50 by connected entrance 210 is flowed into is full of.And ink also flow in the second air cell 200b bit by bit from the first air cell 200a side, this second air cell 200b is communicated with the first air cell 200a by the communication path 221 of the linearity corresponding with the 230a of elongated slot portion.
But, in this case, due to below the part of the communication path 221 of linearity under inverted state is also positioned at, therefore, when the part of this communication path 221 has been full of by ink, in this communication path 221, also cannot carry out gas-liquid exchange.As a result, in ink chamber 50, produce negative pressure, this negative pressure and water-head balance, ink stops to the inflow of air chamber 200 sides.
In addition, even if applied the vibration with the acceleration on fore-and-aft direction Y under this state, as shown in Figure 59 and Figure 60, flow into the first air cell 200a of being communicated with by communication path 221 and the ink in the second air cell 200b also just applying in the direction of acceleration back and forth, can further not flow out in the 3rd air cell 200c as atmospheric air open port 60 sides.
In above-mentioned each embodiment, the distance between the first opening 211 and the second opening 212 and spaced walls 48b also can be unequal.For example, the tenth variation that also can be is as shown in Figure 61 such, the first opening 211 is formed on and is sowed discord near next door 48b end face farthest, and the second opening 212 is formed near spaced walls 48b.In addition, in this case, as shown in Figure 62, the elongated slot portion on the lateral surface of side 48c of housing container 48 of being formed on also can form the 230a-230c of elongated slot portion of the linearity of inclination.
In this case, under inversion state, in communication path 221 corresponding to the 230a of elongated slot portion with linearity, the part of the first opening 211 is positioned at below, therefore when ink is filled to the part of the first opening 211 of this communication path 221, in this communication path 221, cannot carry out gas-liquid exchange.Therefore, in ink chamber 50, produce negative pressure, this negative pressure and water-head balance, ink stops to the inflow of air chamber 200 sides.
In above-mentioned each embodiment, the communication path 221,223,225 that is communicated with respectively the first air cell 200a and the second air cell 200b, the 3rd air cell 200c and the 4th air cell 200d, the 5th air cell 200e and the 6th air cell 200f also can run through in the spaced walls 201,203,205 that is formed on this each air cell of division.For example, also can not as shown in Figure 63, with the first, the 3rd, the 5th each divide on the side of inner side of wall 201,203, two air cells that 205Wei circle is adjacent and form the first opening 211 and the second opening 212, but as shown in Figure 64 (a) and (b), be to run through on upper two the adjacent division walls of fore-and-aft direction Y form from spaced walls 48b between the different communication path of distance.
Incidentally, Figure 64 (a) illustrates following state: near the spaced walls 48b dividing on wall 202 at the even number (second) second since the first air cell 200a side number, at the corner part place as housing peristome 48a side, communication path 222 runs through formation on fore-and-aft direction Y.In addition, Figure 64 (b) illustrates following state: near the end face farthest of the distance spaced walls 48b on odd number (the 5th) the 5th division wall 205 since the first air cell 200a side number, at the corner part place of the interior dark side as the 5th air cell 200e, communication path 225 runs through formation on fore-and-aft direction Y.
In other words, as the communication path 221,223,225 of an example of the first communication path, in a bight that forms rectangular-shaped odd number and divide the wall of wall, run through formation.On the other hand, communication path 222,224,226 as an example of the second communication path is formed on following bight, described bight is: when odd number being divided to the wall of wall and projects on fore-and-aft direction Y relatively and form equally rectangular-shaped even number and divide on the wall of wall, on this wall with another bight in diagonal position, the bight being projected.
In the situation that forming like this, when being formed on odd number and dividing communication path 221,223,225 on wall as the first communication path running through, to run through when being formed on even number and dividing communication path 222,224,226 on wall as the second communication path, under the inverted state of ink tank 43, the part of a communication path in the first communication path and the second communication path is away from gas-liquid interface.Therefore, in this case, in ink chamber 50, also can produce negative pressure, thereby can suppress ink, from ink chamber 50, flow out.In addition, be not limited to each division wall 201-209 continuous on fore-and-aft direction Y alternately to form the first communication path and the second communication path, for example also can be to form the first communication path on upper at least two the continuous division walls of fore-and-aft direction Y, and be to form the second communication path on upper other at least one the division walls that continue to keep continuous of fore-and-aft direction Y.
In addition, in this case, do not need form to connect the 213a-213c of elongated slot portion of the first opening 211 and the second opening 212 etc., need to not carry out junction film 214 to seal the mode of the opening of the 213a-213c of this elongated slot portion etc. in addition yet, therefore can easily obtain the structure of communication path.And, because the corner part at the diagonal position of rectangular-shaped division wall only forms communication path, so can easily realize the structure of the ink leakage in the time of can suppressing to be inverted.
And, in this case, the first communication path (for example communication path 225) and the second communication path (for example communication path 222) are upper in the direction parallel with spaced walls 48b with the first division wall (as an example, i.e. above-below direction Z and left and right directions X), are mutually configured in different positions.Therefore, not only when turned upside down, for example, under the state of laying across, in the part of the communication path away from gas-liquid interface one side in the first communication path and the second communication path, also can make to carry out gas-liquid exchange, thereby can suppress ink from ink chamber's 50 leakages by produce negative pressure in ink chamber 50.
In the 11 variation shown in Figure 63 and Figure 64, the first communication path and the second communication path are not limited to the diagonal positions of the division wall of rectangle, as long as be formed at respectively different position on above-below direction Z and left and right directions X.In addition, due to when being inverted, a position being positioned at away from gas-liquid interface in the first communication path and the second communication path, therefore this meaning, the first communication path and the second communication path are formed at respectively positions different on above-below direction Z, can make in this case any communication path wherein be positioned at upside.
In the tenth variation shown in Figure 61 and Figure 62, the first opening 211 and the second opening 212 also can be configured to the upside that the second opening 212 under attitude is in use positioned at the first opening 211.
In above-mentioned each embodiment and variation, wriggle and extend the 213a-213c of elongated slot portion of shape and the groove that the sinuous stria 219 that extends shape also can form the curve shapes such as circular-arc or V word shape, in addition, the 230a-230c of elongated slot portion of the stria 215 of linearity and linearity also can form the groove of the non-linear shapes such as extending shape or curved shape of wriggling.And, to cover coating member that the mode of these grooves engages except film, can be also thin resin sheet material or plate etc.
In above-mentioned each embodiment and variation, running through the communication path of division wall 201-209 formation except the mode with rectangular-shaped excision is formed on the corner part of this division wall, can be also the through hole that runs through the surface portion except corner part of dividing wall on thickness direction.
