Therefore, similarly to the window portion 42a, the width of the visual confirmation surface 43a in the vertical direction Z on the front side is larger than the width in the vertical direction Z on the rear side. the

The lower limit scale 64 a is closer to the outlet 59 than the halfway position in the front-back direction Y, and is formed at a position above the outlet 59 . In addition, the upper limit scale 64b is closer to the filling port 52 than the halfway position in the front-rear direction Y, and is formed at a position below the filling port 52 and the air introduction port 60 . Furthermore, the outlet port 59 and the inlet port 52 are formed on the same side (front side) in the front-rear direction Y. Therefore, the lower limit scale 64a is closer to the injection port 52 than the halfway position in the front-back direction Y, and is formed at a position below the injection port 52 and the upper limit scale 64b. Thereby, on the same side in the front-back direction Y of the visual confirmation surface 43a, a plurality of scales with intervals are formed in the up-down direction Z. the

Furthermore, the lower limit scale 64 a indicates the lower limit amount as a reference for injecting ink into the ink chamber 50 . In addition, the upper limit scale 64 b indicates the upper limit amount of ink injected from the injection port 52 and accommodated in the ink chamber 50 . the

An example of the upper opening. Also, the tank container 42 is configured to be larger than the ink tank 43 , and the container opening portion 42 b is larger than the ink tank 43 in the front-back direction Y and the up-down direction Z. the

In addition, on the inside of the right side wall part formed by the window part 42a in the tank container 42, and at a position corresponding to the tank lock part 62 of the ink tank 43, at least one screw-engageable mounting screw 61 is formed (this embodiment way is 2) threaded part 66. In addition, at least one positioning convex portion 67 a , 67 b (two in this embodiment) as an example of a positioning portion is formed at a position corresponding to the positioning concave portion 63 a , 63 b of the ink tank 43 . the

When the tank container 42 is fixed to the device body 13, at least one (5 in this embodiment) is formed on the tank container 42 as an example of a locking portion that locks the screw 36 (see FIG. 12 ) inserted and passed through. a) container locking parts 68a-68e. That is, the first to fifth container lock portions 68a to 68e are configured to correspond to the screw bosses 37 formed on the mounting surface 13a. In addition, an engaging portion 69 capable of engaging with the boss portion 38 is formed at a position corresponding to the boss portion 38 of the device main body 13 in the tank container 42 . the

In addition, as shown in FIGS. 12 and 13, a handle portion 71 is formed at a position below the window portion 42a in the tank container 42, and at a position between the fourth container locking portion 68d and the fifth container locking portion 68e. . In addition, at the position where the fourth container lock portion 68d and the fifth container lock portion 68e are formed on the lower surface of the tank container 42, an engagement recess 72 that engages with the reinforcement rib 34f on the mounting surface 13a side is formed on the container opening 42b side. . the

In addition, as shown in FIGS. 12 and 14 , at a position on the front side of the upper surface of the tank container 42 , a trough portion 42 c having a height one step lower than the upper surface in the vertical direction Z is formed. And the 1st container lock part 68a is located in this valley part 42c. In addition, a covering portion 73 that covers the first container locking portion 68a from the rear and above and is open on the right side is formed around the first container locking portion 68a. Therefore, the screw 36 screwed to the first container lock portion 68 a is covered by the cover portion 73 for a user looking down on the tank unit 27 . the

In addition, as shown in FIG. 14 , a U-shaped receiving portion 74 is formed in the valley portion 42c when viewed from above. The left side on the 42b side enters into the valley portion 42c. In addition, a mounting portion 75 is formed behind the receiving portion 74 in the trough portion 42c. The mounting portion 75 is positioned one step higher than the position formed by the receiving portion 74 and can mount the closing member 58 thereon. Therefore, the length of the tie portion 58 a is set such that the closing member 58 can be selected from the cylindrical portion 53 and the mounting portion 75 . the

The mounting portion 75 is composed of an annular portion 75a and a cross portion 75b, wherein the annular portion 75a is formed in an annular shape whose inner peripheral shape is slightly larger than the outer peripheral shape of the fitting portion 58c of the closing member 58, and the cross portion 75b is positioned at The inner side of the annular portion 75a is smaller than the inner peripheral shape of the fitting portion 58c. Moreover, the cross portion 75b is a shape in which two vertical plate portions extending in the front-rear direction Y and the left-right direction X intersect in a cross shape, and on each side surface of each vertical plate portion in the front-rear direction Y and the left-right direction X, a The protrusion 75 c extending in the up-down direction Z and having a substantially triangular shape in plan view protrudes from the side. Therefore, when the closing member 58 is placed on the mounting part 75, the fitting part 58c is located inside the annular part 75a, and is supported in a state where its inner peripheral surface abuts against the projection 75c of the cross part 75b. the

As shown in FIGS. 12 and 14 , the tank container 42 is formed with a pair of rail portions 76a, 76b extending in the front-rear direction Y, and the rail portions 76a, 76b serve as supporting members for slidably supporting the cover 44 in the front-rear direction Y. one example. Moreover, between the pair of guide rails 76a and 76b, a plurality of (three in this embodiment) convex lines 77 extending in the front-rear direction Y are formed. Furthermore, among the pair of guide rails 76a, 76b, the rear end upper surface of the first guide rail portion 76a located on the right and the rear end upper surface (omitted in the figure) of the second guide rail portion 76b located on the left side are chamfered. the

As shown in FIG. 12, a pair of stopper recessed part 78a, 78b which has space|interval in the front-back direction is formed in the 1st rail part 76a. Of the front and rear inner surfaces of each of the pair of stopper recesses 78 a and 78 b , the inner surfaces constituting the opposing recess side are chamfered. That is, the rear inner surface of the first front stopper recess 78a is chamfered, and the front inner side surface of the second rear stopper recess 78b is chamfered. the

As shown in FIG. 15, the cover 44 has the upper wall 44a, the right wall 44b connected to this upper wall 44a, the left wall 44c, and the rear wall 44d, respectively. Further, the height of the right wall 44b and the rear wall 44d in the up-down direction Z is substantially the same, whereas the height of the left wall 44c is lower than that of the right wall 44b and the rear wall 44d. the

On the inner surface of the right wall 44b on the side of the left wall 44c, a pair of sliding contact portions 80 are formed at intervals in the front-rear direction Y to engage and slide in contact with the first rail portion 76a. Further, on the inner surface of the left wall 44c on the right wall 44b side, a pair of sliding contact portions 80 are formed at intervals in the front-rear direction Y to engage and slide in contact with the second rail portion 76b. Furthermore, the respective sliding contact portions 80 are formed with positions shifted in the front-rear direction Y to be different from each other. In addition, on the sliding contact portion 80 located on the front side among the pair of sliding contact portions 80 formed on the right wall 44b, a stopper convex portion 80a capable of engaging with the stopper concave portions 78a, 78b is formed. the

Further, the cover 44 is slidable in the front-rear direction Y between a shielding position A shown in FIG. 16 and a non-shielding position B shown in FIG. 17 . In the shielding position A, the stop convex portion 80a cooperates with the stop concave portion 78a, and in the non-shielding position B, the stop convex portion 80a cooperates with the stop concave portion 78b. the

Specifically, as shown in FIGS. 16 and 18 , when the stopper convex portion 80 a is engaged with the first stopper concave portion 78 a, the cover 44 is located at a shielding position for shielding the cylinder portion 53 on which the injection port 52 is formed and the mounting portion 75 . a. the

On the other hand, as shown in FIG. 17 and FIG. 19, when the stop convex portion 80a is engaged with the second stop concave portion 78b, the cover 44 is located at a non-shielding position B different from the shielding position A, and an injection port 52 is formed at this time. The cylindrical part 53 and the mounting part 75 will be exposed. the

Moreover, as shown in FIGS. 16 and 18 , the size of the cover 44 in the front-rear direction Y is smaller than that of the tank container 42 . In addition, when the ink tank 43 is fixed in the tank container 42, the cylindrical portion 53 is configured such that the end surface 52a of the filling port 52 is higher than the receiving portion 74 of the tank container 42, and the height of the closing member 58 fitted with the cylindrical portion 53 It is lower than the cover 44 in the shielding position A. the

In addition, as shown in Figure 12, Figure 16, Figure 17, each screw 36 that is screwed with the 2nd container locking part 68b and the 3rd container locking part 68c is covered by the cover 44 that is installed on the tank container 42. Moreover, the screw 36 screwed together with the 4th container lock part 68d and the 5th container lock part 68e is covered by the tank unit 27 from the user who overlooks the tank unit 27. the

In addition, as shown in FIG. 3 , an anti-slip portion 82 is formed on the upper wall 44 a of the cover 44 . The anti-slip portion 82 has a substantially triangular shape as a whole and protrudes upward. In addition, a label 83 is attached to the back of the anti-slip portion 82 on the cover 44, and the label 83 is marked with signs such as letters and figures indicating the type of ink contained in the tank unit 27, and warnings such as warnings about the injection of different types of ink. information, information on how to inject ink and precautions, etc. Moreover, the same label 83 is also pasted on the right side of the can container 42 and on the concave portion 46 on the front surface, and on the mounting surface 13a at the place where the cover 44 is held when the cover 44 is in the shielding position A. 44, and when the cover 44 is in the non-shielding position B, it is exposed. the

Next, the maximum fluctuation range of the liquid level 51 of the ink and the state in which the ink is supplied from the ink tank 43 to the liquid ejection head 32 will be described. the

The recording device 12 of this embodiment supplies the ink contained in the ink chamber 50 to the liquid ejection head 32 using a water level difference. Therefore, if the liquid level 51 fluctuates greatly in the vertical direction Z, ink cannot be supplied from the ink tank 43 to the liquid ejection head 32 satisfactorily. Specifically, when the liquid ejection head 32 is located at a relatively low position from the liquid surface 51, there is a possibility that ink may leak from the liquid ejection head 32; position, there is a possibility that ink cannot be supplied to the liquid ejection head 32. the

Therefore, as shown in FIG. 20 , in the recording device 12 according to this embodiment, when the maximum fluctuation range of the liquid surface 51 of the ink in the vertical direction Z is 75 mm or more, the ink cannot be supplied to the liquid jet head 32 satisfactorily. . That is, for example, in the case where the liquid ejection head 32 is arranged corresponding to the time when the ink chamber 50 contains the maximum amount of ink, when the ink is consumed and the liquid level 51 drops, even if the ink remains in the ink chamber 50, it cannot be discharged. Ink is supplied to the liquid ejection head 32 . Also, for example, when the liquid ejection head 32 is arranged so that the ink in the ink chamber 50 is consumed and the liquid level 51 drops, the ink may leak from the liquid ejection head 32 when the maximum amount of ink is contained. the

On the other hand, when the maximum fluctuation range of the liquid level 51 of the ink in the vertical direction Z is set to be 70 mm or less, even if the maximum amount of ink is accommodated in the ink chamber 50, or even when the liquid level 51 of the ink in the ink chamber 50 falls , the ink can also be supplied to the liquid jet head 32 . the

However, in the case where the maximum fluctuation range of the liquid level 51 is 70 mm, the liquid ejection head 32 and the ink tank 43 have installation errors and manufacturing errors, and the ink cannot be supplied satisfactorily. Therefore, when the maximum fluctuation range is set to be 55 mm or less, ink can be supplied to the liquid ejection head 32 satisfactorily even if there are slight mounting errors and manufacturing errors. In addition, when the maximum fluctuation range is 40 mm or less, ink can be satisfactorily supplied from the ink tank 43 to the ejection head 32 even when, for example, the installation surface of the recording device 12 is slightly inclined. the

Therefore, as shown in FIG. 21 , in this embodiment, the height h1 in the vertical direction Z from the lower limit scale 64 a to the upper limit scale 64 b is set to be 40 mm or less. That is, when the ink liquid level 51 falls to the lower limit scale 64a, the user injects ink from the injection port 52, and the ink liquid level 51 rises to the upper limit scale 64b. Therefore, when the liquid ejection head 32 is normally used, the fluctuation range of the ink liquid level 51 is equal to the height h1, and the ink in the ink chamber 50 can be well supplied to the liquid ejection head 32 when the height h1 is 40 mm or less. the

In addition, the height h2 in the up-down direction Z from the lower end of the opening of the outlet port 59 formed in the ink chamber 50 to the upper limit scale 64 b is set to be 55 mm or less. Therefore, ink can be supplied to the liquid ejection head 32 even if, for example, ink remains in the ink chamber 50 when the user continues printing without noticing that the liquid level 51 of the ink has dropped to the lower limit scale 64 a. the

In addition, the height h3 in the vertical direction Z from the lower end of the opening of the outlet port 59 formed in the ink chamber 50 to the end surface 52 a of the inlet port 52 is set to be 70 mm or less. That is, the height h3 is made to correspond to the maximum fluctuation range of the ink contained in the ink tank 43 . Therefore, even when the ink overflows from the injection port 52 as the user injects ink into the ink chamber 50 , for example, ink leakage from the liquid ejection head 32 can be suppressed. the

Next, the shape of the ink chamber 50 will be described. the

Therefore, when the height of the ink chamber 50 in the vertical direction Z is restricted, ink can be supplied to the liquid ejection head 32 satisfactorily, but the amount of ink that can be accommodated in the ink chamber 50 decreases. Therefore, the ink tank 43 of this embodiment secures the amount of ink that can be accommodated in the ink chamber 50 by increasing the width in the front-rear direction Y and increasing the horizontal cross-sectional area. the

Specifically, as shown in FIG. 22, the size of the ink chamber 50 in the left-right direction X is defined as depth D, the size in the front-back direction Y is defined as width W, and the size in the vertical direction Z is defined as Let it be height H. And, when the ink chamber 50 leads out from the outlet 59 the equivalent ink of 5% of the capacity that can be accommodated in the ink chamber 50, the fluctuation range of the liquid level 51 of the ink in the ink chamber 50 has the capacity that can be accommodated in the ink chamber 50. The range below 5% of the cube root of the quantity (for example, at least the range of height h1 in Fig. 21). In addition, in the following description, the condition related to the shape of the ink chamber 50 is referred to as a shape condition, and the capacity that can be accommodated in the ink chamber 50 is referred to as a maximum capacity. the

For example, when the ink chamber 50 has a cubic shape in which the depth D along the left-right direction X, the width W along the front-back direction Y, and the height H along the up-down direction Z are respectively equal (D=W=H), the liquid surface 51 of the ink is The shape condition is satisfied in any position. Specifically, in the case of a cube shape, in the case of deriving 5% of the maximum storage capacity, the fluctuation range (0.05×D×W×H/(D×W)) of the liquid level 51 and the cube root of the maximum storage capacity 5% (0.05×(D×W×H) ^1/3 ) is equal.

Therefore, any rectangular parallelepiped shape that is longer in the front-rear direction Y or in the left-right direction X than the cubic shape satisfies the shape condition. That is, when the height H of the ink chamber 50 is smaller than the depth D and width W, the shape condition is satisfied. Specifically, the shape condition is satisfied as long as the bottom area (D×W) of the ink chamber or the area of the liquid surface 51 (horizontal cross-sectional area of the ink chamber 50 ) is at least the square of the height H. However, there are cases where the shape condition is satisfied when the height H is larger than either of the depth D and the width W. For example, even if the depth D is half of the height H, the shape condition can be satisfied if the width W is twice or more than the height H. the

Next, the fluctuation range of the liquid level 51 of the ink in the ink chamber 50 when the ink corresponding to 5% of the maximum storage capacity is drawn out will be described. the

When the ink equivalent to 5% of the maximum storage capacity is derived, the minimum fluctuation range (hereinafter referred to as the minimum fluctuation range) of the liquid level 51 of the ink in the ink chamber 50 is more than 6% of the cube root of the maximum storage capacity. The amount of ink that can be accommodated in the ink chamber 50 is sufficiently secured. the

On the other hand, when the minimum fluctuation range is 5% or less of the cube root of the maximum storage capacity, ink can be sufficiently contained in the ink chamber 50, but it is preferable that the minimum fluctuation range is 4% or less of the cubic root of the maximum storage capacity. the

Next, the action when the device main body 13 is fixed to the ink tank 43 will be described. the

As shown in FIG. 4 , first, the ink tank 43 is inserted from the container opening 42 b of the tank container 42 , and the positioning protrusions 67 a , 67 b and the positioning recesses 63 a , 63 b are concave-convexly fitted and positioned. In addition, the ink tank 43 is fixed in the tank container 42 by screwing the mounting screw 61 on the tank locking portion 62 and the screwing portion 66 . That is, the tank container 42 protects the ink tank 43 by covering the ink tank 43 from the outside. the

Next, as shown in FIG. 12 , the tank container 42 to which the ink tank 43 is fixedly mounted is fitted on the mounting surface 13 a. That is, the first rib 34 is surrounded by the tank container 42 , the boss portion 38 is engaged with the engaging portion 69 , and the reinforcing rib 34 f is engaged with the engaging recess 72 . the

In addition, as shown in FIG. 6, when the tank container 42 mounted with the ink tank 43 is positionally matched with the mounting surface 13a, the absorbing member 39 is located between the injection port 52 and the device body 13, thereby absorbing ink that adheres when the ink is injected. Ink flowing out from around the injection port 52 after being attached or around the injection port 52 . Furthermore, the absorbing member 39 has a thickness larger than that of the upper rib 34a in the left-right direction X. As shown in FIG. Therefore, the absorbing member 39 installed between the device body 13 and the ink tank 43 is pressed in between by the device body 13 and the ink tank 43 , thereby being compressed and deformed. the

In addition, as shown in FIG. 12 , the container locking portions 68 a to 68 e coincide with the screw bosses 37 in a state where the tank container 42 is aligned with the mounting surface 13 a. Therefore, when the screws 36 are screwed on the container locking portions 68a to 68e, the respective container locking portions 68a to 68e are screwed to the screw bosses 37, whereby the tank container 42 and the device main body 13 are fixedly mounted. the

Furthermore, when the tank container 42 is attached to the device body 13 , the container opening 42 b of the tank container 42 is covered by the device body 13 . Therefore, the device main body 13 and the tank container 42 realize its function as an example of a protective member that covers and can protect the ink tank 43 from the outside. An example of a system. the

Next, with the tank container 42 fixed to the device main body 13 , the cover 44 is attached from the rear of the tank container 42 so that the rail portions 76 a , 76 b and the sliding contact portion 80 fit together. the

Therefore, as shown in FIGS. 17 and 19 , first, the cover 44 is located at the non-shielding position B where the stopper convex portion 80 a cooperates with the second stopper recess 78 b located on the rear side. Then, push forward the cover 44 that is positioned at the non-shielding position B, so that the stop convex portion 80a is mounted on the inner surface of the chamfering front side of the second stop concave portion 78b, thereby releasing the stop convex portion 80a and the second stop concave portion 78b. The engagement of the stopper recess 78b moves the cover 44 forward. the

Then, as shown in FIG. 16 and FIG. 18 , the cover 44 is located at the shielding position A where the stopper protrusion 80 a and the first stopper recess 78 a cooperate. Moreover, since the inner surface on the rear side of the first stopper recess 78a is chamfered, when the cover 44 at the shielding position A is pushed backward, the stopper convex part 80a is placed on the chamfer of the first stopper recess 78a. On the inner surface of the side, the engagement between the stopper protrusion 80a and the first stopper recess 78a is released, and the cover 44 moves backward. the

Next, the operation when injecting ink into the ink tank 43 will be described. the

When the liquid level 51 of the ink contained in the ink tank 43 drops to the lower limit scale 64a, the user slides the cover 44 backward from the shielding position A to the non-shielding position B (see FIG. 17 ). Then, the closing member 58 and the mounting portion 75 covered by the cover 44 located at the blocking position A are exposed. the

Next, the user moves the closing member 58 fitted to the tip of the cylindrical portion 53 toward the mounting portion 75 and injects ink from the injection port 52 . Furthermore, the injected ink can be confirmed from the window portion 42 a of the tank container 42 . the

Even when ink spillage occurs with the injection of ink, the leaked ink flows away from the device main body 13 along the inlet forming surface 54 and is caught by the catching protrusion 55 . Moreover, even if the amount of leaked ink is large, if the ink passes over the intercepting convex portion 55, the leaked ink will expand and spread along the step portion 54a, thereby changing the direction of leakage. In addition, even if ink splashes toward the apparatus main body 13 side, the leaked ink can be absorbed by the absorbing member 39 installed between the apparatus main body 13 and the tank unit 27 . the

Then, when the liquid level 51 rises to the upper limit scale 64b with the injection of ink, the user ends the injection of ink, returns the closing member 58 placed on the mounting portion 75 to the cylindrical portion 53, and slides the cap 44 forward. , so that it moves to the sheltered position A. the

According to the first embodiment described above, the following effects can be obtained. the

(1) Ink can be injected into the ink chamber 50 from the inlet 52 formed in the ink tank 43 . In addition, since the tank unit 27 is fixed to the device body 13 , when the user carries the recording device 12 , the possibility of the tank unit 27 detaching from the device body 13 can be reduced. Therefore, the transportability of the recording device 12 including the tank unit 27 capable of filling ink can be improved. the

(2) Since the cover 44 is slidably provided, the space for changing the position of the cover 44 can be reduced compared with, for example, changing the position between the shielding position and the non-shielding position by rotating the cover about an axis. Therefore, even when the recording device 12 is installed in a narrow place, the cover 44 can be opened and closed. the

(3) When injecting ink into the ink chamber 50 through the injection port 52 , the closing member 58 can be placed on the mounting portion 75 first. Therefore, even when ink adheres to the sealing member 58 , it is possible to reduce the possibility that the ink adheres to parts other than the mounting portion 75 . the

(4) Since the injection port 52 is formed on the cylindrical portion 53 that protrudes to the outside of the ink chamber 50, when the ink is injected into the ink chamber 50, it is possible to reduce the amount of content caused by components located around the cylindrical portion 53 and the injected ink. (Large ink containers, etc.) may abut against ink injection. In addition, since the cylindrical portion 53 protrudes toward the upper right, which is not perpendicular to the vertical direction Z, the user can easily confirm the state of the ink injection. the

(5) By providing the catching protrusion 55 on the inlet forming surface 54 constituting the flow path of the leaked ink, the ink leaked from the inlet 52 can be blocked. the

(6) By suppressing the fluctuation range of the liquid level 51 with respect to the amount of ink led out from the ink chamber 50 , it is possible to reduce fluctuations in the pressure applied to the ink supplied to the liquid ejection head 32 . Therefore, the ink contained in the ink chamber 50 can be stably supplied to the liquid jet head 32 side. the

(7) Since the width of the ink chamber 50 along the front-back direction Y intersecting the up-down direction Z is larger than the height along the up-down direction Z, the width in the front-back direction Y is smaller than the height in the up-down direction Z In comparison, fluctuations in the liquid level 51 with respect to the amount of ink drawn out can be reduced. the

(8) By setting the height h3 from the outlet 59 to the inlet 52 to be 70 mm or less, the height from the outlet 59 to the inlet 52 can be suppressed, and the liquid level 51 of the ink contained in the ink chamber 50 can be lowered in the vertical direction. Changes in Z. the

(9) By setting the height h2 from the outlet 59 to the upper limit scale 64b to be 55 mm or less, the range of the position of the liquid surface 51 in the ink chamber 50 can be set to 55 mm or less, thereby further reducing the amount of water contained in the ink chamber 50. The liquid level 51 of the ink fluctuates in the up and down direction Z. the

(10) The user can use the lower limit scale 64 a as a reference for injecting ink into the ink chamber 50 . In addition, by setting the height h1 from the lower limit scale 64 a to the upper limit scale 64 b to be 40 mm or less, the range of the position of the liquid surface 51 in the ink chamber 50 can be set to 40 mm or less. Therefore, fluctuations in the vertical direction Z of the liquid level 51 of the ink contained in the ink chamber 50 can be further reduced. the

(11) The lower limit scale 64a and the upper limit scale 64b are formed on the visual confirmation surface 43a, and are located on the front side of the halfway position in the front-back direction Y, that is, on one side. Therefore, unlike the case where it is formed on both sides, even when the ink tank 43 is installed obliquely, it can be lowered at a plurality of positions different in the front-rear direction Y, and the position of the liquid surface 51 with respect to each position in each up-down direction can be lowered. Different possibilities for scales 64a, 64b on Z. Therefore, the user can easily confirm the amount of ink contained in the ink tank 43 visually. the

(12) By forming the lower limit scale 64 a on the side of the outlet 59 , it is possible to compare the ink liquid level 51 located near the outlet 59 with the lower limit scale 64 a. Therefore, when the user uses the lower limit scale 64a as a reference for injecting ink into the ink chamber 50, the possibility of supplying air from the outlet 59 due to the ink liquid level 51 being below the outlet 59 in the vertical direction Z is reduced. the

(13) Since the lower limit scale 64 a is formed on the same side as the injection port 52 and is formed below the injection port 52 , when ink is injected from the injection port 52 , the injected ink can be easily confirmed. the

(14) In the case where the ink tank 43 is installed in an inclined state in the ink tank 43 having a visually recognizable surface 43a whose width Y in the front-rear direction is larger than the height in the up-down direction Z, different positions in the front-rear direction Y On the other hand, the difference in the position of the liquid surface 51 in the up-down direction Z with respect to the scales 64a, 64b tends to increase. In this regard, since the scales 64a and 64b are formed on the front side rather than the halfway position in the horizontal direction, even when the ink tank 43 is installed obliquely, the amount of ink can be easily confirmed visually. the

(15) Since the upper limit scale 64a is formed on the injection port 52 side, for example, even if the ink tank 43 is installed at an inclination, by comparing the liquid level 51 of the injected ink with the upper limit scale 64b, ink leakage from the injection port 52 can be reduced. possibility. the

(16) Since the visual confirmation surface 43 a is formed to face rightward intersecting the vertical direction Z, the liquid surface 51 of the comparison ink and the scales 64 a and 64 b can be visually confirmed from one side. the

(17) Since the plurality of scales 64a, 64b are formed on the same side, the remaining amount of ink contained in the ink chamber 50 can be easily visually confirmed by comparing the ink liquid level 51 with each scale 64a, 64b. the

(18) Since the end surface 52 a of the injection port 52 is not perpendicular to the vertical direction Z, ink can be injected more easily than when the end surface 52 a of the injection port 52 is perpendicular to the vertical direction Z. the

(19) When the ink tank 43 is fixed to the device body 13 , the cylindrical portion 53 is formed to be inclined in a direction away from the device body 13 , so that ink can be injected more easily. the

(20) Since the injection forming surface 54 is non-perpendicular to the up-down direction Z, even if the ink leaks from the injection port 52, the ink can flow along the injection port forming surface 54, thereby reducing the tendency of the ink to flow undesired by the user. Possibility of directional flow. the

(21) Since the inclinations of the cylindrical portion 53 and the inlet forming surface 54 with respect to the vertical direction Z are the same, for example, when the ink tank 43 is injection-molded, the cylindrical portion 53 and the inlet forming surface 54 can be formed with the same mold. the

(22) Leaked ink leaked from the injection port 52 is stopped by the catch protrusion 55 on the injection port forming surface 54 constituting the leaked ink flow path, thereby reducing the possibility of the leaked ink contaminating the surroundings. the

(23) Since the blocking convex portion 55 is located above the visual confirmation surface 43 a, the possibility of contamination of the visual confirmation surface 43 a by leaked ink can be reduced. the

(24) Even when the leaked ink passes over the catching convex portion 55 , the possibility of the leaked ink flowing to the visual confirmation surface 43 a can be reduced by the step portion 54 a. the

(25) Since the width of the blocking protrusion 55 in the front-rear direction Y is larger than the width of the injection port 52 , when the ink injected from the injection port 52 leaks in any direction, it can be blocked by the blocking protrusion 55 . ink. the

(26) The injection port forming surface 54 can be used as a flow path for leaked ink. Therefore, by receiving the leaked ink with the inlet forming surface 54, the possibility of ink contaminating parts other than the inlet forming surface 54 can be reduced. the

(27) Leaked ink can be blocked by the catching protrusion 55 protruding from the inlet forming surface 54 . the

(28) Since the injection port 52 and the catching protrusion 55 are formed on the injection port forming surface 54 facing in one direction, the flow direction of the leaked ink can be set in one direction. the

(29) Since the inclinations of the filling port 52 and the blocking protrusion 55 with respect to the vertical direction Z are the same, for example, when the ink tank 43 is injection-molded, the filling port 52 and the blocking protrusion 55 can be formed with the same mold. the

(30) By installing the absorbing member 39 between the device body 13 and the ink tank 43 , the leaked ink can be absorbed even when the leaked ink leaked from the injection port 52 enters between the device body 13 and the ink tank 43 Part 39 absorbs. Therefore, it is possible to reduce the possibility that leaked ink contaminates the surroundings. the

(31) By providing the absorbing member 39 between the injection port 52 that may leak ink and the device main body 13 , the absorbing member 39 can efficiently absorb leaked ink that leaks from the injection port 52 . the

(32) The gap between the device main body 13 and the ink tank 43 can be filled with the absorbing member 39 . Therefore, it is possible to reduce the possibility of foreign matter being mixed into the gap between the device main body 13 and the ink tank 43 . the

(33) Assemblability of the tank unit 27 can be improved by designing the tank container 42 covering the ink tank 43 as an integral molding. the

(34) The ink tank 43 can be easily accommodated in the tank container 42 from the container opening 42 b formed in the tank container 42 . the

(35) Since the ink tank 43 and the tank container 42 are positioned by the positioning recessed portions 63 a , 63 b and the positioning convex portions 67 a , 67 b , the possibility of misalignment of the positions of the ink tank 43 and the tank container 42 is reduced. the

(36) Since the ink tank 43 and the tank container 42 are concavo-convexly fitted and positioned with the elongated hole-shaped positioning concave portion 63a, even if the molding accuracy of the ink tank 43 and the tank container 42 is low, the ink tank 43 and the tank container 42 can be aligned. The tank container 42 is positioned. In addition, since the positioning concave portion 63a is long in the front-rear direction Y, it is possible to suppress the inclination of the ink tank 43 and the tank container 42 in the horizontal direction and perform positioning. the

(37) Since the tank container 42 has the handle portion 71 , the tank unit 27 can be easily carried. the

(38) When the tank unit 27 is fixed on the device body 13, since the fourth container locking portion 68d and the fifth container locking portion 68e formed on both sides of the handle portion 71 lock the screw 36, the user will By placing it on the handle portion 71, the device main body 13 and the tank unit 27 can be transported stably. the

(39) Since the size of the cap 44 is smaller than that of the can container 42 , the cap 44 can be easily housed in the can container 42 . Therefore, even in the case where the tank unit 27 includes the cover 44, the possibility of the cover 44 being caught during transportation can be reduced. the

(40) By enlarging the horizontal cross-sectional area of the ink chamber 50 , it is possible to reduce the variation range of the amount of ink drawn out from the outlet 59 with respect to the liquid surface 51 . That is, since a large amount of ink can be drawn out with a small fluctuation of the liquid level 51 , the ink accommodated in the ink chamber 50 can be stably supplied to the liquid jet head 32 side. the

(41) Since the tank unit 27 is fixed to the device main body 13 , it can be downsized compared to an independent tank unit in which the tank unit 27 is detachably provided to the device main body 13 . In addition, the tank unit 27 and the device main body 13 can be given a sense of unity. the

(42) Since the cover 44 moves between the shielding position A and the non-shielding position B while being supported on the tank container 42 , the possibility of the cover 44 coming off when the multifunction device 11 is transported can be reduced. the

(43) The upper surfaces of the rear ends of the rail portions 76 a , 76 b are chamfered, and the sliding contact portions 80 of the cover 44 are formed differently in the front-rear direction. Therefore, the lid 44 can be easily attached to the tank container 42 . the

(44) Since the tank container 42 is chamfered around the window portion 42a, the entirety of the visual confirmation surface 43a can be easily visually recognized from the outside through the window portion 42a from a lateral direction that does not directly face the window portion 42a. . the

(45) Since the valve stem 47 is provided on the concave portion 46 , misoperation due to the valve stem 47 colliding with surrounding objects can be prevented when the multifunction device 11 to which the tank unit 27 is fixed is transported. the

(46) Since the tank container 42 is integrally molded and has no seams, it is possible to reduce the possibility of accidentally forming a flow path for ink leakage. the

(47) By installing the absorbing member 39 between the device main body 13 and the ink tank 43 , the film 49 can be protected by the absorbing member 39 . the

(48) Even if ink adheres to the sealing member 58 placed on the mounting portion 75 , since the sealing member 58 is placed inside the annular portion 75 a, even if the ink drips from the sealing member 58 , the ink can also be suppressed from spreading around by the annular portion 75a. the

(49) By covering the air inlet 60 with the tank container 42 , it is possible to reduce the possibility that the user injects ink into the air inlet 60 by mistake. the

(50) It is necessary to manage the water level position of the ink liquid surface 51 in the ink tank 43 on the nozzle surface of the liquid ejection head 32 where the nozzles for ejecting ink are formed. In this regard, the ink tank 43 can be mounted on the device main body 13 through the integrally formed tank container 42 including the positioning protrusions 67a, 67b. That is, the ink tank 43 can be attached to the device main body 13 while maintaining the positional relationship between the ink tank 43 and the liquid ejection head 32 with higher accuracy than when the tank container 42 is composed of a plurality of components. the
