As shown in Figure 12, Figure 14, in can container 42, be formed with pair of guide rails portion 76a, 76b of extending on fore-and-aft direction Y, this rail portion 76a, 76b cover the example that 44 modes can slided on fore-and-aft direction Y support the support portion of this lid 44.Further, between pair of guide rails portion 76a, 76b, multiple (being three in the present embodiment) raised line 77 that Y along the longitudinal direction extends is formed.In addition, in pair of guide rails portion 76a, 76b, rear end end face (the omitting diagram) chamfering of the rear end end face being positioned at the first rail portion 76a on right side and the second rail portion 76b being positioned at left side.

As shown in figure 12, the first rail portion 76a is formed with tool in the longitudinal direction spaced a pair backstop recess 78a, 78b.In this pair backstop recess 78a, 78b former and later two medial surfaces separately, near the medial surface chamfering of the recess side of the other side.That is, the medial surface chamfering of the rear side of the first backstop recess 78a of front side, and the medial surface chamfering of the front side of the second backstop recess 78b of rear side.

As shown in figure 15, cover 44 and there is upper wall 44a and the right wall 44b be connected with this upper wall 44a respectively, left wall 44c, rear wall 44d.In addition, right wall 44b is roughly the same with the height on the above-below direction Z of rear wall 44d, and on the other hand, the height of left wall 44c is lower than the height of right wall 44b and rear wall 44d.

On the inner surface on the surface as left wall 44c side of right wall 44b, be formed and coordinate and the pair of sliding contact site 80 slidingly contacted with the first rail portion 76a, this pair of sliding contact site 80 has interval on fore-and-aft direction Y.In addition, on the inner surface on the surface as right wall 44b side of left wall 44a, be formed and coordinate and the pair of sliding contact site 80 slidingly contacted with the second rail portion 76b, this pair of sliding contact site 80 has interval on fore-and-aft direction Y.In addition, each sliding contacting part 80 is formed on fore-and-aft direction Y staggered positions and inequality.Further, be formed in the pair of sliding contact site 80 on right wall 44b, on the sliding contacting part 80 being positioned at front side, be formed with the stop ledge 80a that can coordinate with backstop recess 78a, 78b.

And, lid 44 slides mobile between hidden position A and non-obstructing position B on fore-and-aft direction Y, described hidden position A is the position shown in Figure 16 that stop ledge 80a coordinates with backstop recess 78a, and described hidden position B is the position shown in Figure 17 that stop ledge 80a coordinates with backstop recess 78b.

Specifically, as shown in Figure 16, Figure 18, when stop ledge 80a coordinates with the first backstop recess 78a, lid 44 is positioned to cover and is formed with the cylinder portion 53 of inlet 52 and the hidden position A of mounting portion 75.

On the other hand, as shown in Figure 17, Figure 19, when stop ledge 80a coordinates with the second backstop recess 78b, lid 44 is positioned at the non-obstructing position B different from hidden position A, and the cylinder portion 53 and the mounting portion 75 that are formed with inlet 52 reveal.

In addition, as shown in Figure 16, Figure 18, the size of the lid 44 on fore-and-aft direction Y is less than the size of can container 42, and when lid 44 is positioned at hidden position A, lid 44 is accommodated in can container 42.In addition, cylinder portion 53 is formed as: when ink tank 43 is fixed in can container 42, and the end face 52a of inlet 52 is higher than the receptacle 74 of can container 42, and the lid 44 that the aspect ratio of the packaged unit 58 chimeric with cylinder portion 53 is positioned at hidden position A is low.

In addition, as shown in Figure 12, Figure 16, Figure 17, the lid 44 that each screw 36 screwed togather with second container sticking department 68b and the 3rd container lock bonding part 68c is installed in can container 42 covers.Further, the screw 36 screwed togather with the 4th container lock bonding part 68d and the 5th container lock bonding part 68e is covered by this tank unit 27 relative to the user looking down tank unit 27.

In addition, as shown in Figure 3, on the upper wall 44a of lid 44, being formed with global shape is the anti-slip section 82 that subtriangular mode is given prominence to upward.And, the position being positioned at the rear of anti-slip section 82 on lid 44 is pasted with label 83, and this label 83 records the word that represents the kind being contained in ink in tank unit 27 or figure etc., warns the warning messages such as the injection of different types of ink, about information such as the method for implanting of ink and points for attention.In addition, same label 83 is also pasted onto the place as described below on the right flank of can container 42, the recess 46 being positioned at front surface and installed surface 13a: covered by this lid 44 when lid 44 is positioned at hidden position A and the place revealed when this lid 44 is positioned at non-obstructing position B.

Next, the maximum amplitude of fluctuation of the liquid level 51 of ink is described and supplies the state of ink from ink tank 43 to jet head liquid 32.

The tape deck 12 of present embodiment utilizes water-head to be contained in the ink feed liquid injector head 32 in ink chamber 50.Therefore, when liquid level 51 changes significantly on above-below direction Z, ink cannot be supplied from ink tank 43 well to jet head liquid 32.Specifically, when jet head liquid 32 is positioned at the position more much lower than liquid level 51, may from jet head liquid 32 leak ink, on the other hand, when jet head liquid 32 is positioned at a lot of position higher than liquid level 51, possibly cannot by ink feed to jet head liquid 32.

As shown in figure 20, in the tape deck 12 of present embodiment, when the maximum amplitude of fluctuation on the above-below direction Z of the liquid level 51 (with reference to Fig. 6) of ink is more than or equal to 75mm, ink cannot be supplied well to jet head liquid 32.Namely, such as when with ink chamber 50 in contain the ink of maximum situation correspondingly configure jet head liquid 32, then when ink is consumed and causes liquid level 51 have dropped, even if remain ink in ink chamber 50, also cannot by ink feed to jet head liquid 32.In addition, the situation such as causing liquid level 51 to decline being consumed with the ink in ink chamber 50 correspondingly configures jet head liquid 32, then, when containing 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 the liquid level 51 of ink be less than or equal to 70mm, even if when then containing the ink of maximum in ink chamber 50, even if or the liquid level 51 of ink in ink chamber 50 declines, also can by ink feed to jet head liquid 32.

But, when the maximum amplitude of fluctuation of liquid level 51 is 70mm, sometimes ink cannot be supplied well due to the assembly error of jet head liquid 32 and ink tank 43 or foozle.Therefore, if make maximum amplitude of fluctuation be less than or equal to 55mm, there is some assembly errors or foozle even if then how many, also ink can be fed to jet head liquid 32 well.Further, when making maximum amplitude of fluctuation be less than or equal to 40mm, even if how many installation surfaces of such as tape deck 12 exists some, also ink can be supplied from ink tank 43 well to jet head liquid 32.

Therefore, as shown in figure 21, in the present embodiment, the height h1 from lower limit scale 64a to the above-below direction Z of upper limit scale 64b is made to be less than or equal to 40mm.That is, when the liquid level 51 of ink drops to lower limit scale 64a, user injects ink from inlet 52, makes the liquid level 51 of ink rise to upper limit scale 64b.Therefore, due to can be equal with height h1 by the amplitude of fluctuation of the liquid level 51 of ink when usually using jet head liquid 32, if therefore make h1 be less than or equal to 40mm, then the ink in ink chamber 50 can be supplied to jet head liquid 32 well.

In addition, make height h2 be less than or equal to 55mm, described height h2 is that the lower end (example of bottom surface) of opening from the export mouth 59 be formed in ink chamber 50 is to the height on the above-below direction Z of upper limit scale 64b.Therefore, even if such as user does not notice that the liquid level 51 of ink have decreased to lower limit scale 64a and proceeds printing, as long as remain ink in ink chamber 50, just ink can be supplied to jet head liquid 32.

Further, make height h3 be less than or equal to 70mm, described height h3 is the height on the above-below direction Z of end face 52a from the lower end of the opening of the export mouth 59 be formed in ink chamber 50 to inlet 52.That is, height h3 is equivalent to the maximum amplitude of fluctuation being contained in the ink in ink tank 43.Therefore, even if such as inject ink along with user in ink chamber 50 and overflowed ink from inlet 52, ink also can be suppressed to spill from jet head liquid 32.

Next, the shape of ink chamber 50 is described.

If the height on the above-below direction Z of limit ink room 50, then ink can be fed to jet head liquid 32 well, but the amount being contained in the ink in ink chamber 50 can tail off.Therefore, the ink tank 43 of present embodiment is passed through the size on increase fore-and-aft direction Y and increases horizontal sectional area, ensure that the quantity of ink that can be contained in ink chamber 50.

Specifically, as shown in figure 22, the size on the left and right directions X of ink chamber 50 is set to depth D, the size on fore-and-aft direction Y is set to width W, the size on above-below direction Z is set to height H.And, if from export mouth 59 be derived be equivalent to the capacity that ink chamber 50 can hold 5% ink, the amplitude of fluctuation of the liquid level 51 of the ink then in ink chamber 50 has the region region of height h1 (such as, be at least in figure 21) of less than 5% of the cubic root of the capacity that ink chamber 50 can hold.In addition, in the following description, the condition relevant to the shape of ink chamber 50 is called shape conditions, and the saturation that ink chamber 50 can hold is called maximum capacity.

Such as, when ink chamber 50 is cubic shaped of height H all equal (D=W=H) on the depth D on left and right directions X, the width W on fore-and-aft direction Y, above-below direction Z, no matter where the liquid level 51 of ink is positioned at, and all meets shape conditions.Specifically, when for cubic shaped, 5% (0.05 × (D × W × H) of the amplitude of fluctuation (0.05 × D × W × H/ (D × W)) of liquid level 51 when being derived 5% of maximum capacity and the cubic root of maximum capacity ^1/3) equal.

Therefore, if rectangular shape longer on fore-and-aft direction Y or left and right directions X compared with cubic shaped, then shape conditions is met.That is, when the height H of ink chamber is less than depth D and width W, shape conditions is met.Specifically, the floor space (D × W) of ink chamber or the area (horizontal sectional area of ink chamber 50) of liquid level 51 are more than or equal to the quadratic power of height H, then meet shape conditions.But, even if height H is greater than one in depth D and width W, sometimes also meet shape conditions.Such as, even if depth D is the half of height H, if width W is more than or equal to the twice of height H, then shape conditions is met.

Next, illustrate be derived be equivalent to maximum capacity 5% ink time ink chamber 50 in the amplitude of fluctuation of ink level 51.

If when being derived the ink of be equivalent to maximum capacity 5%, 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 6% of the cubic root of maximum capacity, then cannot guarantee the amount of the ink be contained in ink chamber 50 fully.

On the other hand, if minimum change amplitude is less than or equal to 5% of the cubic root of maximum capacity, then in ink chamber 50, ink can be held fully, but preferably minimum change amplitude is less than or equal to 4% of the cubic root of maximum capacity.

Below, operation when ink tank 43 being fixed on device body 13 is described.

As shown in Figure 4, first insert ink tank 43 from the opening of container 42b of can container 42, make positioning convex portion 67a, 67b and location indentations 63a, 63b male-female engagement to carry out contraposition.Then, mounting screw 61 is screwed togather with tank sticking department 62 and screw part 66, thus ink tank 43 is fixed in can container 42.That is, can container 42 is by protecting this ink tank 43 from outer side covers ink tank 43.

Then, as shown in figure 12, the can container 42 and the installed surface 13a contraposition that are fixed with ink tank 43 is made.That is, can container 42 surrounds first rib 34, makes boss portion 38 coordinate with auxiliary section 69 simultaneously, and reinforcing ribs 34f is coordinated with cooperating recesses 72.

In addition, as shown in Figure 6, when after the can container 42 making to be provided with ink tank 43 and installed surface 13a contraposition, absorption piece 39 is between inlet 52 and device body 13.In addition, absorption piece 39 has larger thickness compared with upper flank 34a on left and right directions X.Therefore, the absorption piece 39 between device body 13 and ink tank 43 is clamped by device body 13 and ink tank 43 and extrudes and compressive deformation occurs.

Further, as shown in figure 12, in can container 42 with under the state of installed surface 13a contraposition, container lock bonding part 68a ~ 68e is consistent with screw bosses portion 37.Therefore, when making screw 36 screw togather with container lock bonding part 68a ~ 68e, each container lock bonding part 68a ~ 68e and screw bosses portion 37 screw togather, and can container 42 are fixedly connected with device body 13.

In addition, when can container 42 is arranged on device body 13, the opening of container 42b of can container 42 is covered by device body 13.Therefore, device body 13 and can container 42 are as an example of the guard block of ink tank 43 being protected to play function from outer side covers, and device body 13, can container 42, ink tank 43, absorption piece 39 constitute an example of liquid-supplying system.

Then, under the state that can container 42 is fixed on device body 13, from the rear mounting cover 44 of can container 42, rail portion 76a, 76b are coordinated with sliding contacting part 80.

Further, as shown in Figure 17, Figure 19, first stop ledge 80a matches with the second backstop recess 78b being positioned at rear side, and lid 44 is positioned at non-obstructing position B.Then, when the lid 44 being positioned at non-obstructing position B is pushed away forward further, stop ledge 80a climbs up the medial surface of the front side of the chamfering of the second backstop recess 78b, thus removes coordinating of stop ledge 80a and the second backstop recess 78b, and lid 44 is forwards moved.

So as shown in Figure 16, Figure 18, stop ledge 80a matches with the first backstop recess 78a, lid 44 is positioned at hidden position A.In addition, due to the medial surface chamfering of the rear side of the first backstop recess 78a, therefore when the lid 44 being positioned at hidden position A is rearward pushed away, stop ledge 80a climbs up the medial surface of the rear side through chamfering of the first backstop recess 78a, thus remove coordinating of stop ledge 80a and the first backstop recess 78a, lid 44 is rearward moved.

Next, operation when injecting ink to ink tank 43 is described.

Once the liquid level 51 being contained in the ink in ink tank 43 have decreased to lower limit scale 64a, lid 44 rearward slides from hidden position A and moves to non-obstructing position B (with reference to Figure 17) by user.So the packaged unit 58 covered by the lid 44 being positioned at hidden position A and mounting portion 75 reveal.

Then, the packaged unit 58 of the top tabling with cylinder portion 53 moves to mounting portion 75 by user, injects ink from inlet 52 simultaneously.In addition, can confirm from the window portion 42a of can container 42 ink that is injected into.

When causing ink to overflow in the injection with ink, leak ink flows along inlet forming surface 54 to the direction away from device body 13, and is blocked protuberance 55 and tackles.Further, even if more in the amount of leak ink, just in case when having crossed interception protuberance 55, leak ink also can change has leaked direction, spreads along stage portion 54a.Further, even if such as when ink splashes to device body 13 side, also leak ink can be absorbed by the absorption piece 39 be arranged between device body 13 and tank unit 27.

Further, when making liquid level 51 rise to upper limit scale 64b when the injection along with ink, user stops the injection of ink, and the packaged unit 58 be placed in mounting portion 75 is got back into a portion 53, and movement of forwards being slided by lid 44 makes it move to hidden position A.

According to above-mentioned first embodiment, following effect can be obtained.

(1) ink can be injected from the inlet 52 be formed at ink tank 43 in ink chamber 50.In addition, because tank unit 27 is fixed on device body 13, therefore, it is possible to reduce the possibility of the tank unit 27 release unit body 13 when user carries tape deck 12.Therefore, it is possible to improve the handlability with the tape deck 12 of the tank unit 27 that can inject ink.

(2) be set to owing to covering 44 movement of can sliding, therefore with such as centered by axle swivelling cover 44 make compared with the situation of its movement between hidden position and non-obstructing position, the area of space of lid 44 movement can be reduced.Therefore, even if tape deck 12 is arranged on narrow and small place, also opening and closing can be carried out to lid 44.

(3) when injecting ink via inlet 52 in ink chamber 50, packaged unit 58 can be placed in mounting portion 75.Therefore, even if ink is attached on packaged unit 58, the possibility that ink is attached to the part beyond mounting portion 75 can also be reduced.

(4) because inlet 52 is formed in the cylinder portion 53 protruding outside of ink chamber 50, when injecting ink in ink chamber 50, the parts be positioned at around a portion 53 can be reduced and abut to the upper and possibility that hinders ink to inject of the contents (large-scale ink tank etc.) injecting ink.Further, because cylinder portion 53 is to outstanding with above-below direction Z off plumb upper right, user is enable easily to confirm the state that ink injects.

(5) because the inlet forming surface 54 of the stream as leak ink is provided with interception protuberance 55, can the ink spilt from inlet 52 be tackled.

(6) by suppressing liquid level 51 relative to the amplitude of fluctuation of the amount of the ink of deriving from ink chamber 50, the pressure change of the ink supplied to jet head liquid 32 can be reduced.Therefore, it is possible to stably the ink be contained in ink chamber 50 is supplied to jet head liquid 32.

(7) because ink chamber 50 is larger than the height of above-below direction Z at the width of the fore-and-aft direction Y intersected with above-below direction Z, the situation less than the height of above-below direction Z with the width of fore-and-aft direction Y is compared, and can reduce the variation of liquid level 51 relative to the amount of the liquid of deriving.

(8) by being less than or equal to 70mm by being set to from export mouth 59 to the height h3 of inlet 52, the height from export mouth 59 to inlet 52 can be suppressed.Therefore, it is possible to reduce the variation of ink level 51 on above-below direction Z be contained in ink chamber 50.

(9) by being less than or equal to 55mm by being set to from export mouth 59 to the height h2 of upper limit scale 64b, the position range of the liquid level 51 in ink chamber 50 can be made at below 55mm.Therefore, it is possible to reduce the variation of ink level 51 on above-below direction Z be contained in ink chamber 50 further.

(10) user can using lower limit scale 64a as the benchmark injecting ink in ink chamber 50.Further, by being less than or equal to 40mm by being set to from lower limit scale 64a to the height h1 of upper limit scale 64b, the position range of the liquid level 51 in ink chamber 50 can be made at below 40mm.Therefore, it is possible to reduce the variation of ink level 51 on above-below direction Z be contained in ink chamber 50 further.

(11) lower limit scale 64a is formed on visual confirming face 43a with upper limit scale 64b and compares closer to front side with the half-way of fore-and-aft direction Y, namely by the position of side.Therefore, different with the situation being formed at both sides, even if ink tank 43 is obliquely installed, also can reduce in the multiple positions different with fore-and-aft direction Y, in each position the position of liquid level 51 on above-below direction Z relative to the different possibility of scale 64a, 64b.Therefore, user's easily visual confirmation is enable to be contained in the amount of the ink in ink tank 43.

(12) by forming lower limit scale 64a in export mouth 59 side, can compare the ink level 51 be positioned near export mouth 59 and lower limit scale 64a.Therefore, by user using lower limit scale 64a as the benchmark injecting ink in ink chamber 50, ink level 51 can be reduced and on above-below direction Z, be positioned at the below of export mouth 59 and cause from the air fed possibility of export mouth 59.

(13) because lower limit scale 64a is formed at the homonymy of inlet 52, and being formed at the lower position of inlet 52, therefore when injecting ink from inlet 52, easily can confirming the ink injected.

(14) in the ink tank 43 with visual confirming face 43a, the width of described visual confirming face 43a on fore-and-aft direction Y is larger than the height on above-below direction Z, when ink tank 43 is set to heeling condition, diverse location on fore-and-aft direction Y, liquid level 51 easily becomes large relative to the position difference of scale 64a, 64b on above-below direction Z.In this respect, because scale 64a, 64b are formed at the position compared with the centre position of horizontal direction closer to front side, even if therefore ink tank 43 is obliquely installed, also can the amount of easily visual confirmation ink.

(15) because upper limit scale 64b is formed at inlet 52 side, even if such as ink tank 43 is obliquely installed, by the ink level 51 of injection and upper limit scale 64b being compared, the possibility that ink overflows from inlet 52 can be reduced.

(16) because visual confirming face 43a is to be formed towards the mode of the right intersected with above-below direction Z, therefore, it is possible to compare ink level 51 and scale 64a, 64b from a direction by visualization.

(17) because multiple scale 64a, 64b are formed at homonymy, therefore by ink level 51 and each scale 64a, 64b being compared, just easily visual confirmation ink surplus in ink chamber 50 can be contained in.

(18) due to end face 52a and the above-below direction Z out of plumb of inlet 52, therefore vertical with above-below direction Z with the end face 52a of inlet 52 situation is compared, and more easily can inject ink.

(19) when ink tank 43 is fixed on device body 13, because cylinder portion 53 is formed as tilting, therefore, it is possible to more easily inject ink towards the direction away from device body 13.

(20) due to inlet forming surface 54 and above-below direction out of plumb, even if therefore ink spills from inlet 52, also can flow along inlet forming surface 54.Therefore, it is possible to reduce the possibility of ink to user's undesirable direction flowing.

(21) when ink tank 43 is fixed on tape deck 13, the end face 52a due to inlet 52 is formed as tilting, therefore, it is possible to more easily inject ink towards the direction away from device body 13.

(22) because cylinder portion 53 and inlet forming surface 54 are identical relative to the respective gradient of above-below direction Z, therefore such as when ink tank 43 injection molding, identical mould molding cylinder portion 53 and inlet forming surface 54 can be used.

(23) leak ink spilt from inlet 52 is blocked protuberance 55 and tackles, and described interception protuberance 55 is positioned in the inlet forming surface 54 as leak ink stream.Therefore, it is possible to reduce surrounding environment by the possibility of inkiness spilt.

(24) because interception protuberance 55 is positioned at the top of visual confirming face 43a, therefore, it is possible to reduce the possibility that visual confirming face 43a polluted by leak ink.

(25) even if leak ink has crossed interception protuberance 55, also can reduce by stage portion 54a the possibility that leak ink flows to visual confirming face 43a.

(26) width owing to tackling the fore-and-aft direction Y of protuberance 55 is larger than the width of inlet 52, and the ink no matter injected from inlet 52, to where spilling, can both be blocked at interception protuberance 55.

(27) can using the stream of inlet forming surface 54 as leak ink.Therefore, by receiving leak ink with inlet forming surface 54, the part beyond inlet forming surface 54 can be reduced by the possibility of inkiness.

(28) by the interception protuberance 55 outstanding from inlet forming surface 54, leak ink can be tackled.

(29) because inlet 52 and interception protuberance 55 are formed in inlet forming surface 54 facing one direction, therefore, it is possible to make the flow direction of leak ink be a direction.

(30) because inlet 52 and interception protuberance 55 are identical relative to the respective gradient of above-below direction Z, therefore such as when ink tank 43 injection molding, identical mould molding inlet 52 and interception protuberance 55 can be used.

(31) by absorption piece 39 is arranged between device body 13 and ink tank 43, even if between the leak ink access to plant body 13 spilt from inlet 52 and ink tank 43, leak ink also can be made to be absorbed by absorption piece 39.Therefore, it is possible to reduce surrounding environment by the possibility of inkiness spilt.

(32) by absorption piece 39 is arranged on ink may spill between inlet 52 and device body 13, absorption piece 39 can be made to absorb the leak ink spilt from inlet 52 efficiently.

(33) absorption piece 39 can be filled in the space between device body 13 and ink tank 43.Therefore, it is possible to reduce the possibility that foreign matter is mixed into the space of device body 13 and ink tank 43.

(34) by the can container 42 covering ink tank 43 is designed to one-body molded thing, thus the drillability rate of tank unit 27 can be improved.

(35) can easily from the opening of container 42b be formed at can container 42, ink tank 43 be contained in can container 42.

(36) due to ink tank 43 and can container 42 by location indentations 63a, 63b and positioning convex portion 67a, 67b locate, therefore, it is possible to the possibility of skew occurs in the position reducing ink tank 43 and can container 42.

(37) chimericly to position because ink tank 43 and can container 42 and the location indentations 63a of elongated hole-shape are concavo-convex, even if therefore when the formed precision of ink tank 43 and can container 42 is low, also ink tank 43 and can container 42 can be positioned.Further, because location indentations 63a is longer on fore-and-aft direction Y, therefore, it is possible to suppress ink tank 43 and can container 42 inclination in the horizontal direction to position.

(38) because can container 42 has handle portion 71, therefore, it is possible to easily carry tank unit 27.
