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

Specifically, as shown in Figure 16, Figure 18, in the situation that backstop protuberance 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, in the situation that backstop protuberance 80a coordinates with the second backstop recess 78b, lid 44 is positioned at the non-hidden 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 in the situation that lid 44 is positioned at hidden position A, lid 44 is accommodated in can container 42.In addition, cylinder portion 53 forms: in the situation that ink tank 43 is fixed in can container 42, the end face 52a of inlet 52 is than the receptacle of can container 42 74 height, and to be positioned at the lid 44 of hidden position A low with the aspect ratio of cylinder portion 53 chimeric packaged unit 58.

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

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

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.

As shown in figure 20, 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 21, in the present embodiment, make the height h1 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 the liquid level 51 of ink that can be when conventionally using jet head liquid 32 equates with height h1, if therefore make h1 be less than or equal to 40mm, 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 lower end (example of bottom surface) from being formed on the opening of the export mouth 59 ink chamber 50 to the height on the above-below direction Z of upper limit scale 64b.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, as long as remain ink in ink chamber 50, just can be to jet head liquid 32 supply inks.

And, make height h3 be less than or equal to 70mm, described height h3 is that the lower end of opening from being formed on the export mouth 59 ink chamber 50 is to the height on the above-below direction Z of the end face 52a of inlet 52.That is, height h3 is equivalent to be contained in the maximum amplitude of fluctuation of the ink in ink tank 43.Therefore, even for example along with user has been overflowed ink to the interior infusing ink of ink chamber 50 from inlet 52, also can suppress ink and 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 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, as shown in figure 22, the size on the left and right directions X of ink chamber 50 is made as to depth D, the size on fore-and-aft direction Y is made as to width W, the size on above-below direction Z is made as to height H.And, if derived 5% the ink that is equivalent to capacity that ink chamber 50 can hold from export mouth 59, the amplitude of fluctuation of the liquid level 51 of the ink in ink chamber 50 has the region below 5% (for example, being at least the region of height h1 in Figure 21) of the cubic root of the capacity that ink chamber 50 can hold.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 ink chamber 50 can be held 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) of the cubic root of maximum capacity ^1/3) 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 (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 device body 13 is described.

As shown in Figure 4, first from the opening of container 42b of can container 42, insert ink tank 43, make that positioning convex portion 67a, 67b and location indentations 63a, 63b are concavo-convex coordinates to carry out contraposition.Then, mounting screw 61 and tank sticking department 62 and screw part 66 are screwed togather, thereby 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, make to be fixed with the can container 42 and installed surface 13a contraposition of ink tank 43.That is, can container 42 is surrounded first ribs 34, makes boss portion 38 coordinate with auxiliary section 69 simultaneously, and makes to strengthen flank 34f and coordinate with cooperating recesses 72.

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

And as shown in figure 12, 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,, when screw 36 and container lock bonding part 68a～68e are screwed togather, each container lock bonding part 68a～68e and screw bosses portion 37 screw togather, and can container 42 is 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 be as can and protecting an example performance function of the guard block of ink tank 43 from outer side covers, and device body 13, can container 42, ink tank 43, absorption piece 39 have formed an example of liquid-supplying system.

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

And as shown in Figure 17, Figure 19, first backstop protuberance 80a matches with the second backstop recess 78b that is positioned at rear side, lid 44 is positioned at non-hidden position B.Then, when being positioned at the lid 44 of non-hidden position B and further being pushed away forward, backstop protuberance 80a climbs up the medial surface of front side of the chamfering of the second backstop recess 78b, thereby removes coordinating of backstop protuberance 80a and the second backstop recess 78b, makes to cover 44 and forwards moves.

So as shown in Figure 16, Figure 18, backstop protuberance 80a matches with the first backstop recess 78a, lid 44 is positioned at hidden position A.In addition, medial surface chamfering due to the rear side of the first backstop recess 78a, therefore when being positioned at the lid 44 of hidden position A and rearward being pushed away, backstop protuberance 80a climbs up the medial surface of the rear side through chamfering of the first backstop recess 78a, thereby releasing backstop protuberance 80a coordinates with the first backstop recess 78a's, makes to cover 44 and rearward moves.

Operation while next, illustrating to ink tank 43 infusing ink.

Once be contained in the liquid level 51 of the ink in ink tank 43, dropped to lower limit scale 64a, user rearward slides lid 44 and moves to non-hidden position B(with reference to Figure 17 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 the packaged unit 58 of the top tabling with cylinder portion 53 to mounting portion 75, simultaneously from inlet 52 infusing inks.In addition, can confirm the ink being injected into from the window portion 42a of can container 42.

In the situation that follow the injection of ink, cause ink to overflow, leak ink forms face 54 along inlet and flows to the direction away from device body 13, and is blocked protuberance 55 and tackles.And even more in the amount of leak ink, just in case crossed in the situation of interception protuberance 55, leak ink also can change leakage direction, spreads along stage portion 54a.And, even for example when ink splashes to device body 13 sides, also can absorb leak ink by the absorption piece 39 being arranged between device body 13 and tank unit 27.

And when making liquid level 51 rise to upper limit scale 64b along with the injection of ink, user stops the injection of ink, and the packaged unit 58 loading in mounting portion 75 is got back into a portion 53, and lid 44 is forwards slided and mobile it moved to hidden position A.

According to above-mentioned the first embodiment, can obtain following effect.

(1) can be from being formed at the inlet 52Xiang ink chamber 50 interior infusing inks ink tank 43.In addition, because tank unit 27 is fixed on device body 13, therefore can reduce the possibility of tank unit 27 release unit bodies 13 when user carries tape deck 12.Therefore, can improve the handlability of the tape deck 12 with tank unit 27 that can infusing ink.

(2) because lid 44 is set to the movement of can sliding, therefore with for example centered by axle swivelling cover 44 its situation mobile between hidden position and non-hidden position is compared, can reduce to cover 44 area of space that move.Therefore,, even tape deck 12 is arranged on to narrow and small place, also can open and close covering 44.

(3) when via inlet 52Xiang ink chamber 50 interior infusing ink, packaged unit 58 can be loaded in mounting portion 75.Therefore,, even if ink is attached on packaged unit 58, also can reduce the possibility that ink is attached to mounting portion 75 part in addition.

(4) because inlet 52 is formed in the cylinder portion 53 of giving prominence to the outside of ink chamber 50, during Dang Xiang ink chamber 50 interior infusing ink, can reducing a portion that is positioned at 53 parts around, to abut to the contents (large-scale ink tank etc.) of infusing ink upper and hinder the possibility that ink injects.Further, because cylinder portion 53 is to outstanding with above-below direction Z off plumb upper right, make user can easily confirm the state that ink injects.

(5) the inlet formation face 54 due to the stream as leak ink is provided with interception protuberance 55, can tackle the ink spilling from inlet 52.

(6) by suppressing liquid level 51 with respect to the amplitude of fluctuation of the amount of the ink of deriving from ink chamber 50, can reduce to the pressure variation of the ink of jet head liquid 32 supplies.Therefore, can stably the ink being contained in ink chamber 50 be 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 with above-below direction Z intersection, compare with the situation that the width of fore-and-aft direction Y is less than the height of above-below direction Z, can reduce liquid level 51 with respect to the change of the amount of the liquid of deriving.

(8) by the height h3 from export mouth 59 to inlet 52 is made as and is less than or equal to 70mm, can suppress the height from export mouth 59 to inlet 52.Therefore, can reduce to be contained in the change on above-below direction Z of ink level 51 in ink chamber 50.

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

(10) user can be using lower limit scale 64a as the benchmark to ink chamber's 50 interior infusing inks.And, by the height h1 from lower limit scale 64a to upper limit scale 64b is made as and is less than or equal to 40mm, can make the position range of the liquid level 51 in ink chamber 50 below 40mm.Therefore, can further reduce to be contained in the change on above-below direction Z of ink level 51 in ink chamber 50.

(11) lower limit scale 64a is formed at Visual Confirmation face 43a with upper limit scale 64b and above compares more close front side with the half-way of fore-and-aft direction Y, leans on the position of a side.Therefore, different with the situation that is formed at both sides, even if ink tank 43 is obliquely installed, also can reduce in a plurality of positions different with fore-and-aft direction Y, the position that is set up liquid level 51 at everybody on above-below direction Z with respect to the different possibilities of scale 64a, 64b.Therefore, make user easily Visual Confirmation be contained in the amount of the ink in ink tank 43.

(12), by forming lower limit scale 64a in export mouth 59 sides, can compare being positioned near export mouth 59 ink level 51 and lower limit scale 64a.Therefore, by user using lower limit scale 64a as the benchmark to ink chamber's 50 interior infusing inks, can reduce ink level 51 on above-below direction Z, be positioned at export mouth 59 below 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 be formed at the lower position of inlet 52, therefore, when from inlet 52 infusing ink, can easily confirm the ink injecting.

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

(15), because upper limit scale 64b is formed at inlet 52 sides, even if for example ink tank 43 is obliquely installed, by the ink level of injection 51 and upper limit scale 64b are compared, can reduce the possibility that ink overflows from inlet 52.
