In the first embodiment, the visual recognition part 50 is formed on two surfaces, ie, the front surface 43 and the upper surface 45 of the container body 41 respectively. Therefore, in the first embodiment, the visual recognition portion 50 provided on the front surface 43 of the container body 41 is referred to as the first visual recognition portion 51 , and the visual recognition portion 50 provided on the upper surface 45 of the container main body 41 is referred to as the second visual recognition portion 52 .

The first visual recognition portion 51 is formed at a position near the bottom surface 46 and the left side surface 48 on the front surface 43 of the container body 41 . The second visual recognition portion 52 is formed on the upper surface 45 of the container body 41 at a position closer to the front surface 43 and closer to the left side surface 48 . The second visual recognition portion 52 is formed on the upper surface 45 at a position adjacent to the concave portion 45a. The visual recognition portion 50 may be provided on the rear surface 44, the right side surface 47, or the like.

The visual recognition part 50 is preferably provided on the surface of the container body 41 that corresponds to the surface of the housing 12 on which the opening 30 is provided. For example, if the housing 12 has the opening 30 on its front surface 13 , the visual recognition part 50 is preferably provided on the front surface 43 of the container body 41 . If the housing 12 has the opening 30 on its upper surface 15 , the viewing portion 50 is preferably provided on the upper surface 45 of the container body 41 . This makes it easier to visually recognize the remaining amount of liquid contained in the container body 41 through the opening 30 and the visual recognition portion 50 .

The viewing portion 50 is preferably positioned so as to correspond to the position of the opening 30 when the carriage 23 is positioned at the home position. For example, when the carriage 23 is positioned at the home position, the first viewing portion 51 is preferably located so as to overlap the first opening 31 when the first opening 31 is viewed from the front of the housing 12 . That is, it is preferable that the first visual recognition portion 51 be positioned so as to overlap the first opening 31 in the depth direction Y when the carriage 23 is positioned at the home position.

The second visual recognition part 52 is preferably positioned so as to overlap the second opening 32 when the second opening 32 is viewed from above the housing 12 when the carriage 23 is positioned at the home position. That is, it is preferable that the second visual recognition portion 52 is positioned so as to overlap the second opening 32 in the width direction X when the carriage 23 is positioned at the home position. This makes it easier to visually recognize the remaining amount of the liquid contained in the container body 41 .

The visual recognition part 50 may be formed, for example, on the right side surface 47 of the container body 41 . When the third opening 33 is formed on the right side surface 17 of the housing 12 , the visual recognition part 50 is preferably formed on the right side surface 47 of the container body 41 . In the first embodiment, the visual recognition portion 50 provided on the right side surface 47 of the container body 41 is called a third visual recognition portion 53 . The third visual recognition portion 53 is formed, for example, at a position indicated by a two-dot chain line in FIG. The third viewing portion 53 is preferably located so as to overlap the third opening 33 when the third opening 33 is viewed from the right side of the housing 12 when the carriage 23 is at the home position. That is, it is preferable that the third visual recognition portion 53 be positioned so as to overlap the third opening 33 in the width direction X when the carriage 23 is positioned at the home position.

The container body 41 may be entirely made of a transparent material. In this case, since the entire container body 41 is formed transparent, all surfaces of the container body 41 function as the visual recognition portion 50 . By doing so, the remaining amount of the liquid contained in the liquid container 22 can be visually recognized from any of the first opening 31 , the second opening 32 and the third opening 33 . If the entire container body 41 is made transparent, light incident from the opening 30 can easily reach the inside of the container body 41, and the remaining amount of the liquid contained in the container body 41 can be easily visually recognized.

Next, the action and effect of the liquid storage container 22 of the first embodiment will be described.
(1) At least part of the container body 41 is made of a transparent material. Therefore, the inside of the container body 41 can be visually recognized through the portion formed of the transparent material in the container body 41 . By looking inside the container body 41, the liquid contained in the container body 41 can be visually recognized. Therefore, according to the first embodiment, the remaining amount of liquid contained in the container main body 41 can be visually recognized through the portion of the container main body 41 formed of the transparent material.

(2) When the inside of the housing 12 is viewed from outside the housing 12 through the opening 30 of the housing 12, the visual recognition portion 50 of the container body 41 can be visually recognized. That is, the remaining amount of liquid contained in the liquid container 22 can be visually recognized from outside the housing 12 through the opening 30 of the housing 12 .

(Second embodiment)
Next, a second embodiment of the liquid storage container 22 will be described. In the second embodiment, differences from the first embodiment will be mainly described. In the second embodiment, the shape of the container body 41 is different from that in the first embodiment.

As shown in FIGS. 10 , 11 , 12 , 13 , 14 , 15 and 16 , the container body 41 of the second embodiment has an inclined surface 56 . That is, at least one of the plurality of surfaces forming the container body 41 is the inclined surface 56 . The inclined surface 56 is a surface that slopes toward the inside of the container body 41 from below to above when the container body 41 is mounted on the carriage 23 . That is, the inclined surface 56 is a surface facing upward in the container body 41 . The inclined surface 56 extends vertically in the container body 41 . A plurality of inclined surfaces 56 may be provided on the container body 41 .

The container body 41 has a front surface 43 , a rear surface 44 , a top surface 45 , a bottom surface 46 , a right side 47 and a left side 48 . The perspective view of the liquid storage container 22 shown in FIG. 10 shows the front surface 43 , upper surface 45 and right side surface 47 of the container body 41 . The perspective view of the liquid storage container 22 shown in FIG. 11 shows the rear surface 44 , the lower surface 46 and the left side surface 48 of the container body 41 . The front view of the liquid storage container 22 shown in FIG. 12 shows the front surface 43 of the container body 41 . The rear view of the liquid storage container 22 shown in FIG. 13 is a view showing the rear surface 44 of the container body 41. As shown in FIG. The plan view of the liquid storage container 22 shown in FIG. 14 is a view showing the upper surface 45 of the container body 41. As shown in FIG. The right side view of the liquid storage container 22 shown in FIG. 15 shows the right side 47 of the container body 41 . The left side view of the liquid storage container 22 shown in FIG. 16 shows the left side 48 of the container body 41 . The lower surface 46 of the container body 41 is a rectangular flat surface, like the lower surface 46 of the container body 41 in the first embodiment.

The inclined surface 56 faces forward and upward of the container body 41 when the container body 41 is attached to the carriage 23 . Therefore, in the second embodiment, the inclined surface 56 is composed of the front surface 43 and the upper surface 45 . In other words, the inclined surface 56 constitutes the front surface 43 and the upper surface 45 .

The inclined surface 56 in the second embodiment constitutes the front surface 43 and part of the upper surface 45 . The upper surface 45 has a horizontal portion extending in the width direction X and the depth direction Y and a portion inclined with respect to the horizontal portion. The inclined portion of the upper surface 45 is both the inclined surface 56 and the front surface 43 . The inclined surface 56 is positioned toward the front of the container body 41 on the upper surface 45 . The recessed portion 45 a is located in a horizontal portion extending in the width direction X and the depth direction Y on the upper surface 45 .

An angled surface 56 may be provided to define the rear surface 44 , the right side 47 or the left side 48 . The inclined surface 56 faces rearwardly and upwardly of the container body 41 when forming the rear surface 44 . When forming the right side surface 47 , the inclined surface 56 faces upward and rightward of the container body 41 . When forming the left side surface 48 , the inclined surface 56 faces upward and leftward of the container body 41 .

The sloping surfaces 56 may be provided to form the front surface 43 , the top surface 45 and the right side surface 47 , for example. In this case, the inclined surface 56 is inclined to face forward, upward and rightward of the container body 41 . In this way, the inclined surface 56 may be a surface inclined in three directions on the container body 41 . The shape of the container body 41 having the inclined surface 56 may be changed arbitrarily.

The inclined surface 56 faces at least one of the front, rear, right and left sides of the container body 41 and upward. Therefore, the inclined surface 56 is a surface that can be visually recognized with respect to the container body 41 from directions other than above and below, and from above. In the second embodiment, the inclined surface 56 is visible from the front and above the container body 41 . The inclined surface 56 preferably forms at least one of the front surface 43 , the right side surface 47 and the left side surface 48 and the upper surface 45 .

At least a portion of the inclined surface 56 is made of a transparent material. Therefore, the viewing portion 50 is provided on the inclined surface 56 . In the second embodiment, the area of the inclined surface 56 excluding the edge portion is formed of a transparent material. Thereby, the inside of the container main body 41 can be visually recognized through the inclined surface 56 . In the second embodiment, since the inclined surface 56 forms the front surface 43 and the upper surface 45 , the visual recognition portion 50 provided on the inclined surface 56 is both the first visual recognition portion 51 and the second visual recognition portion 52 . The entire inclined surface 56 may be made of a transparent material. In the second embodiment, the third visual recognition portion 53 may or may not be provided.

The liquid level of the liquid contained in the container main body 41 descends as the remaining amount of the liquid decreases. Therefore, by looking at the level of the liquid contained in the container body 41, it is easy to grasp the remaining amount of the liquid. In this specification, the liquid level position refers to the position of the liquid level in the vertical direction Z.

When the inclined surface 56 is viewed from the front of the container body 41 , the liquid surface position can be visually recognized through the visual recognition portion 50 provided on the inclined surface 56 . As a result, for example, in FIG. 12, when the liquid surface position of the liquid contained in the container body 41 is located near the upper side of the inclined surface 56, it can be grasped that the remaining amount of liquid is large. In FIG. 12, when the liquid surface position of the liquid is positioned toward the lower side of the inclined surface 56, it can be understood that the remaining amount of liquid is small.

When the inclined surface 56 is viewed from above the container body 41 , the edge of the liquid surface can be visually recognized through the visual recognition portion 50 provided on the inclined surface 56 . At this time, the position of the liquid surface can be visually recognized by observing the position of the edge of the liquid surface on the inclined surface 56 . For example, in FIG. 14, when the edge of the liquid surface of the liquid contained in the container body 41 is positioned toward the rear of the container body 41 on the inclined surface 56, it can be visually recognized that the liquid surface position of the liquid is at a high position. That is, it can be grasped that the remaining amount of liquid is large. In FIG. 14, when the edge of the liquid surface of the liquid is positioned toward the front of the container body 41 on the inclined surface 56, it can be visually recognized that the liquid surface position is at a low position. That is, it can be grasped that the remaining amount of liquid is small.

In the second embodiment, the inclined surface 56 can be visually recognized when the container body 41 is viewed from above. Looking at the inclined surface 56 , the liquid surface position of the liquid contained in the container body 41 can be visually recognized through the visual recognition portion 50 provided on the inclined surface 56 . This makes it easy to visually recognize the remaining amount of liquid not only when the container body 41 is viewed from the front but also when viewed from above.

The visual recognition portion 50 may be provided with a scale 57 indicating the remaining amount of the liquid contained in the container body 41 . The scale 57 is formed by drawing with paint or by carving grooves. By comparing the liquid surface position of the liquid with the scale 57, it is easy to visually recognize the remaining amount of the liquid.

According to the second embodiment, the following effects can be obtained in addition to the effects (1) and (2).
(3) The inclined surface 56 is inclined toward the inside of the container body 41 from below to above. Therefore, in the container body 41, the inclined surface 56 faces upward. Since the inclined surface 56 faces upward, the inclined surface 56 can be visually recognized when the container body 41 is viewed from above. Since the inclined surface 56 is made of a transparent material, the level of the liquid contained in the container body 41 can be visually recognized from above through the inclined surface 56 . By looking at the liquid surface position of the liquid, the remaining amount of the liquid can be visually recognized. As described above, according to the second embodiment, the remaining amount of liquid contained in the container body 41 can be easily visually recognized from above the container body 41 .

The perspective view of the liquid container 22 shown in FIG. 18 shows the rear surface 44 , the lower surface 46 and the left side surface 48 of the container body 41 . The front view of the liquid storage container 22 shown in FIG. 19 shows the front surface 43 of the container body 41 . The plan view of the liquid storage container 22 shown in FIG. 20 shows the upper surface 45 of the container body 41. As shown in FIG. The right side view of the liquid storage container 22 shown in FIG. 21 shows the right side 47 of the container body 41 . The left side view of the liquid storage container 22 shown in FIG. 22 shows the left side 48 of the container body 41 . The rear surface 44 and the lower surface 46 of the container body 41 are rectangular flat surfaces, like the rear surface 44 and the lower surface 46 of the container body 41 in the first embodiment.

The step surface 59 faces forward and upward of the container body 41 when the container body 41 is attached to the carriage 23 . Therefore, in the third embodiment, the stepped surface 59 is composed of the front surface 43 and the upper surface 45 . In other words, the step surface 59 constitutes the front surface 43 and the upper surface 45 . The stepped surface 59 of the third embodiment constitutes the front surface 43 and part of the upper surface 45 . The step surface 59 is formed by alternately arranging a portion of the front surface 43 and a portion of the upper surface 45 in the depth direction Y in the container body 41 . As a result, the step surface 59 has a stepped shape.

The front surface 43 has a first front surface 431, a second front surface 432, a third front surface 433, and a fourth front surface 434 in order from the bottom to the top. The top surface 45 has a first top surface 451 , a second top surface 452 , a third top surface 453 , and a fourth top surface 454 in order in the depth direction Y. As shown in FIG.

The step surface 59 is formed by a first front surface 431 , a first upper surface 451 , a second front surface 432 , a second upper surface 452 , a third front surface 433 , a third upper surface 453 and a fourth front surface 434 . By arranging the first front surface 431, the first upper surface 451, the second front surface 432, the second upper surface 452, the third front surface 433, the third upper surface 453, and the fourth front surface 434 in this order in the container body 41, the step surface 59 has a stepped shape. form. The fourth upper surface 454 is provided with the injection part 42 and the recess 45a.

The step surface 59 may be provided to form the rear surface 44 , the right side surface 47 or the left side surface 48 . When forming the rear surface 44 , the stepped surface 59 faces rearwardly and upwardly of the container body 41 . When forming the right side surface 47 , the step surface 59 faces upward and to the right side of the container body 41 . When forming the left side surface 48 , the stepped surface 59 faces upward and leftward of the container body 41 . The shape of the container body 41 having the step surface 59 may be changed arbitrarily.

The step surface 59 is a surface facing at least one of the front, rear, right and left sides of the container body 41 and upward. Therefore, the step surface 59 is a surface that can be visually recognized from above the container body 41 as well as from directions other than above and below. In the third embodiment, the step surface 59 is visible from the front and above the container body 41 . The step surface 59 preferably forms at least one of the front surface 43 , the right side surface 47 and the left side surface 48 and the upper surface 45 .

At least a portion of the step surface 59 is made of a transparent material. Therefore, the visual recognition portion 50 is provided on the step surface 59 . In the third embodiment, the area of the step surface 59 excluding the edge portion is formed of a transparent material. For example, on the stepped surface 59, the portions indicated by the two-dot chain lines in FIGS. 17, 19 and 20 are made of a transparent material. As a result, the inside of the container body 41 can be visually recognized through the step surface 59 . The entire step surface 59 may be made of a transparent material.

The visual recognition part 50 is provided over the first front surface 431 , the first upper surface 451 , the second front surface 432 , the second upper surface 452 , the third front surface 433 , the third upper surface 453 , and the fourth front surface 434 on the step surface 59 . The visual recognition part 50 provided on the first front surface 431 , the second front surface 432 , the third front surface 433 and the fourth front surface 434 is the first visual recognition part 51 . The visible portions 50 provided on the first upper surface 451 , the second upper surface 452 and the third upper surface 453 are the second visible portions 52 . Therefore, the visual recognition portion 50 is formed so that the first visual recognition portions 51 and the second visual recognition portions 52 are alternately arranged on the step surface 59 . The visual recognition portion 50 may be provided on the fourth upper surface 454 . In the third embodiment, the third visual recognition portion 53 may or may not be provided.

As shown in FIG. 19, when the stepped surface 59 is viewed from the front of the container body 41, the first front surface 431, the second front surface 432, the third front surface 433, and the fourth front surface 434 are continuously arranged from the bottom to the top. looks like. Therefore, the first visual recognition portions 51 respectively provided on the first front surface 431, the second front surface 432, the third front surface 433, and the fourth front surface 434 appear to be continuously arranged vertically. At this time, the liquid surface position of the liquid contained in the container body 41 can be visually recognized via the first visual recognition portion 51 . Accordingly, in FIG. 19, when the liquid surface position of the liquid contained in the container main body 41 is positioned near the upper side of the step surface 59, it can be grasped that the remaining amount of liquid is large. In FIG. 19, when the liquid surface position of the liquid is positioned toward the lower side of the step surface 59, it can be grasped that the remaining amount of liquid is small.

As shown in FIG. 20, when the stepped surface 59 is viewed from above the container body 41, the first upper surface 451, the second upper surface 452, the third upper surface 453, and the fourth upper surface 454 are arranged continuously in the depth direction Y. appear. Therefore, the second visual recognition portions 52 provided on the first upper surface 451, the second upper surface 452, and the third upper surface 453 appear to be continuously arranged in the depth direction Y. As shown in FIG. At this time, the appearance of the liquid when the inside of the container body 41 is viewed through the second visual recognition portion 52 varies depending on the remaining amount of the liquid contained in the container body 41 .

When the remaining amount of the liquid contained in the container body 41 is large, for example, when the liquid level is higher than the third upper surface 453, the first upper surface 451, the second upper surface 452, the third upper surface 453, and the liquid surface position are substantially the same in the vertical direction Z. Therefore, when the inside of the container body 41 is viewed through the second visual recognition portion 52 of the first upper surface 451, the second upper surface 452, and the third upper surface 453, the appearance of the liquid becomes uniform. That is, when the appearance of the liquid when viewing the inside of the container body 41 through the second visual recognition portion 52 is uniform, it is possible to visually recognize that the liquid level is at a high position in the container body 41 .

When the remaining amount of the liquid contained in the container body 41 is small, for example, when the liquid surface position is lower than the first upper surface 451, the first upper surface 451, the second upper surface 452, the third upper surface 453, and the liquid surface position are different from each other in the vertical direction Z. Specifically, in the vertical direction Z, the distance between the first upper surface 451 and the liquid level position is shorter than the distance between the second upper surface 452 and the liquid level position. In the vertical direction Z, the distance between the second upper surface 452 and the liquid level position is shorter than the distance between the third upper surface 453 and the liquid level position.

Normally, the longer the distance between the second visual recognition portion 52 and the liquid surface position, the lower the visibility of the liquid when viewing the inside of the container body 41 through the second visual recognition portion 52 . Therefore, when the remaining amount of the liquid is small, the visibility of the liquid through the second visual recognition portion 52 of the first upper surface 451 is high, but the visibility of the liquid through the second visual recognition portion 52 of the third upper surface 453 is low. . That is, when the remaining amount of the liquid is small, the visibility of the liquid visually recognized through the second visual recognition portion 52 decreases as it goes in the depth direction Y. As shown in FIG. In this way, it is possible to visually recognize that the liquid level is at a low position in the container body 41 .

As described above, the liquid surface position of the liquid can be visually recognized by the difference in appearance of the liquid when the inside of the container body 41 is viewed through the second visual recognition portion 52 . That is, the liquid surface position of the liquid can be visually recognized through the stepped surface 59 not only when the container body 41 is viewed from the front but also when viewed from above.

According to the third embodiment, the following effects can be obtained in addition to the effects (1) and (2).
(4) Since the step surface 59 has a stepped shape from the bottom to the top, the step surface 59 can be visually recognized when the container body 41 is viewed from above. Since the step surface 59 is made of a transparent material, the level of the liquid contained in the container body 41 can be visually recognized from above through the step surface 59 . As described above, according to the third embodiment, it is possible to easily visually recognize the remaining amount of the liquid contained in the container body 41 .

(Fourth embodiment)
Next, a fourth embodiment of the liquid storage container 22 will be described. In the fourth embodiment, differences from the first to third embodiments will be mainly described.

As shown in FIGS. 23, 24, 25, 26, 27 and 28, the container body 41 of the fourth embodiment has columns 61. As shown in FIGS. The column 61 is positioned inside the container body 41 and provided to extend vertically when the container body 41 is attached to the carriage 23 . In the fourth embodiment, the post 61 is shaped like a truncated cone. The pillar 61 is not limited to a truncated cone shape, and may be a truncated pyramid shape. The pillar 61 may be conical, pyramidal, cylindrical, or prismatic. The shape of the pillar 61 may be changed arbitrarily.

The column 61 extends upward from the inner bottom surface of the container body 41 . The column 61 of the fourth embodiment is formed such that a portion of the lower surface 46 of the container body 41 is recessed toward the interior of the container body 41 . The pillar 61 is located at a position that can be visually recognized through the visual recognition portion 50 . In the fourth embodiment, the column 61 is positioned closer to the front surface 43 and closer to the left side surface 48 inside the container body 41 . The pillar 61 is positioned so as to overlap the first visual recognition portion 51 in the depth direction Y. As shown in FIG. That is, the column 61 is positioned so as to overlap the first visual recognition portion 51 when the container body 41 is viewed from the front. In this way, when the container body 41 is viewed from the front, the columns 61 can be visually recognized through the first visual recognition portion 51 .

The pillar 61 is positioned so as to overlap the second visual recognition portion 52 in the vertical direction Z. As shown in FIG. That is, the column 61 is positioned so as to overlap the second visual recognition portion 52 when the container body 41 is viewed from above. In this way, when the container body 41 is viewed from above, the column 61 can be visually recognized through the second visual recognition portion 52 .

It is preferable that the pillar 61 has a size that allows its outer shape to be grasped through the first visual recognition portion 51 and the second visual recognition portion 52 . In other words, it is preferable that the first visual recognition portion 51 and the second visual recognition portion 52 have a size that allows the outline of the column 61 to be grasped. The first visual recognition portion 51 in the third embodiment has a rectangular shape extending in the vertical direction Z on the front surface 43 . The second visual recognition portion 52 has a square shape on the upper surface 45 . In the fourth embodiment, the third visual recognition portion 53 may or may not be provided.

When the inside of the container body 41 is viewed through the viewing portion 50, the liquid and the column 61 can be viewed. At this time, a part of the column 61 protrudes from the surface of the liquid inside the container body 41 . The amount of protrusion of the columns 61 protruding from the liquid surface varies depending on the position of the liquid surface. Therefore, it is easy to visually recognize the remaining amount of the liquid by looking at the protrusion amount of the column 61 protruding from the liquid surface of the liquid.

When viewing the container body 41 from the front, the liquid and the column 61 can be visually recognized through the first visual recognition portion 51 . When the amount of protrusion of the column 61 visually recognized through the first visual recognition portion 51 is small, that is, when only the top end portion of the column 61 protrudes from the liquid surface, it is possible to visually recognize that the liquid level is high. . This makes it possible to visually recognize that there is a large amount of liquid remaining.

When the amount of protrusion of the column 61 visually recognized through the first visual recognition portion 51 is large, that is, when the portion closer to the base end on the side opposite to the tip of the column 61 protrudes from the liquid surface, the position of the liquid surface changes. You can see that it's low. This makes it possible to visually recognize that the remaining amount of liquid is small. By providing the pillars 61 in the container body 41 in this way, it is possible to easily visually recognize the remaining amount of the liquid.

The pillars 61 are preferably formed in the shape of a frustum or pyramid. This makes it easier to visually recognize the remaining amount of liquid even when the container body 41 is viewed from above. When the container body 41 is viewed from above, the liquid and the column 61 can be visually recognized through the second visual recognition portion 52 . When the remaining amount of liquid is large, that is, when the liquid level is high, only the tips of the pillars 61 with small diameters protrude from the liquid level. Therefore, the amount of area of the column 61 visually recognized through the second visual recognition part 52 is small. Thereby, it can be visually recognized that the amount of protrusion of the column 61 is small.

When the remaining amount of liquid is small, that is, when the liquid level is low, the portion of the column 61 near the base end, which has a large diameter, protrudes from the liquid level. Therefore, the amount of area of the column 61 visually recognized through the second visual recognition part 52 is large. Thereby, it can be visually recognized that the amount of protrusion of the column 61 is large. The position of the liquid surface can be visually recognized by observing the projection amount of the column 61 projecting from the liquid surface through the second visual recognition portion 52 . By looking at the liquid surface position, the remaining amount of the liquid can be grasped.

When the inside of the container main body 41 is viewed through the viewing portion 50, the column 61 may not protrude from the liquid surface. In this case, the liquid surface position is higher than the tip of the column 61 . Therefore, when the column 61 does not protrude from the liquid surface, it is possible to visually recognize that there is a large amount of liquid remaining.

A light emitter 62 , for example an LED, may be arranged inside the column 61 . In this way, the column 61 is illuminated from the inside by the light emitted from the light emitter 62, so that the amount of protrusion of the column 61 can be easily recognized.

A scale 57 may be provided on the pillar 61 . The scale 57 is preferably formed along the peripheral surface of the pillar 61 . By providing the scale 57 on the column 61, it becomes easier to visually recognize the remaining amount of the liquid.
According to the fourth embodiment, the following effects can be obtained in addition to the effects (1) and (2).

(5) When the inside of the container body 41 is viewed through the viewing portion 50, the projection amount of the columns 61 projecting from the liquid surface of the liquid contained in the container body 41 can be visually recognized. When the amount of protrusion of the column 61 is large, it can be visually recognized that the remaining amount of liquid is small. When the amount of protrusion of the column 61 is small, it can be visually recognized that there is a large amount of remaining liquid. By providing the pillars 61 in this way, it is possible to easily visually recognize the remaining amount of the liquid.

The partition plate 64 is positioned inside the container body 41 and is provided so as to extend vertically when the container body 41 is attached to the carriage 23 . The partition plate 64 partitions the interior of the container body 41 . The partition plate 64 extends upward from the front to the rear of the container body 41 . Therefore, the partition plate 64 is inclined with respect to the front surface 43 , rear surface 44 , upper surface 45 and lower surface 46 of the container body 41 . It can be said that the partition plate 64 is inclined so that its surface faces upward.

The partition plate 64 extends upward from the inner bottom surface of the container body 41 . The partition plate 64 is positioned at a position that can be visually recognized through the visual recognition portion 50 . In the fifth embodiment, the partition plate 64 is positioned closer to the left side surface 48 inside the container body 41 .

The partition plate 64 is positioned so as to overlap the first visual recognition portion 51 in the depth direction Y. As shown in FIG. That is, the partition plate 64 is positioned so as to overlap the first visual recognition portion 51 when the container body 41 is viewed from the front. By doing so, the partition plate 64 can be visually recognized through the first visual recognition portion 51 when the container body 41 is viewed from the front.

The partition plate 64 is positioned so as to overlap the second visual recognition portion 52 in the vertical direction Z. As shown in FIG. That is, the partition plate 64 is positioned so as to overlap the second visual recognition portion 52 when the container body 41 is viewed from above. In this way, the partition plate 64 can be visually recognized through the second visual recognition portion 52 when the container body 41 is viewed from above.

The second visual recognition portion 52 has a rectangular shape extending in the depth direction Y on the upper surface 45 . In the fifth embodiment, the third visual recognition portion 53 may or may not be provided.

When the inside of the container body 41 is viewed through the viewing portion 50, the liquid and the partition plate 64 can be viewed. At this time, a part of the partition plate 64 protrudes from the liquid surface in the container main body 41 . The amount of protrusion of the partition plate 64 that protrudes from the liquid surface varies depending on the position of the liquid surface. Therefore, it is easy to visually recognize the remaining amount of the liquid by looking at the amount of protrusion of the partition plate 64 that protrudes from the surface of the liquid.

When viewing the container body 41 from the front, the liquid and the partition plate 64 can be visually recognized through the first visual recognition portion 51 . When the protrusion amount of the partition plate 64 visually recognized through the first visual recognition part 51 is small, it can be visually recognized that the liquid surface position of the liquid is high. This makes it possible to visually recognize that there is a large amount of liquid remaining.

When the protrusion amount of the partition plate 64 visually recognized through the first visual recognition part 51 is large, it is possible to visually recognize that the liquid level is low. This makes it possible to visually recognize that the remaining amount of liquid is small. By providing the partition plate 64 in the container main body 41 in this way, it is possible to easily visually recognize the remaining amount of the liquid. That is, the partition plate 64 is a member for making it easy to visually recognize the remaining amount of liquid, like the column 61 in the fourth embodiment.

When the container body 41 is viewed from above, the liquid and the partition plate 64 can be visually recognized through the second visual recognition portion 52 . At this time, since the surface of the partition plate 64 faces upward, the edge of the liquid can be visually recognized on the partition plate 64 . The position of the liquid surface can be visually recognized by observing the position of the edge of the liquid surface on the partition plate 64 . In other words, by seeing where the edge of the liquid is on the partition plate 64, the amount of protrusion of the partition plate 64 from the liquid surface can be visually recognized.

In FIG. 32, when the edge of the liquid surface of the liquid contained in the container body 41 is located on the partition plate 64 toward the rear of the container body 41, it can be visually recognized that the liquid surface position of the liquid is at a high position. At this time, it can be visually recognized that the amount of protrusion of the partition plate 64 protruding from the liquid surface is small. That is, it can be grasped that the remaining amount of liquid is large.

In FIG. 32, when the edge of the liquid surface is located on the partition plate 64 toward the front of the container body 41, it can be visually recognized that the liquid surface position is at a low position. At this time, it can be visually recognized that the amount of protrusion of the partition plate 64 protruding from the liquid surface is large. That is, it can be grasped that the remaining amount of liquid is small.

A scale 57 may be provided on the partition plate 64 . If the partition plate 64 is provided with a scale 57, it becomes easier to visually recognize the remaining amount of the liquid.
According to the fifth embodiment, the following effects can be obtained in addition to the effects (1) and (2).

(6) When the inside of the container body 41 is viewed through the viewing portion 50, the protrusion amount of the partition plate protruding from the liquid surface of the liquid contained in the container body 41 can be visually recognized. When the protruding amount of the partition plate is large, it can be visually recognized that the remaining amount of liquid is small. When the protrusion amount of the partition plate is small, it is possible to visually recognize that there is a large amount of remaining liquid. By providing the partition plate in this way, it is possible to easily visually recognize the remaining amount of the liquid.

(Sixth embodiment)
Next, a sixth embodiment of the liquid storage container 22 will be described. In the sixth embodiment, differences from the first to fifth embodiments will be mainly described.

As shown in FIGS. 33, 34, 35 and 36, the container body 41 of the sixth embodiment has partition plates 66. As shown in FIGS. The partition plate 66 is positioned inside the container body 41 and is provided so as to extend vertically when the container body 41 is attached to the carriage 23 . The partition plate 66 is located at a position visible through the first visual recognition portion 51 . The partition plate 66 is positioned so as to overlap the first visual recognition portion 51 in the depth direction Y. As shown in FIG. That is, the partition plate 66 is positioned so as to overlap the first visual recognition portion 51 when the container body 41 is viewed from the front. By doing so, the partition plate 66 can be visually recognized through the first visual recognition portion 51 when the container body 41 is viewed from the front.

The partition plate 66 of the sixth embodiment is formed integrally with the first visual recognition portion 51 . Therefore, the partition plate 66 is made of a transparent material such as glass, plastic, or ceramic, like the first visual recognition portion 51 . In the sixth embodiment, the second visual recognition portion 52 and the third visual recognition portion 53 may or may not be provided.

As shown in FIGS. 37 and 38, the first visual recognition portion 51 has a front surface 67 forming the front surface 43 of the container body 41 and a rear surface 68 on the opposite side. The partition plate 66 extends from the back surface 68 of the first visual recognition portion 51 so as to be curved in an arch shape. 37 is an end view of section AA of FIG. 35 at section C-C' of FIG. 35 and section D-D' of FIG. 36; FIG. 38 is an end view of section BB of FIG. 35 at section C-C' of FIG. 35 and section D-D' of FIG.

The partition plate 66 extends in the vertical direction Z on the rear surface 68 of the first visual recognition portion 51 . In the vertical direction Z, the length of the partition plate 66 is the same as the length of the first visual recognition portion 51 . The partition plate 66 has an arch shape in the width direction X. As shown in FIG. The partition plate 66 curves into a semicircular shape when viewed from above or below the container body 41 . The partition plate 66 is positioned near the center in the width direction X on the rear surface 68 of the first visual recognition portion 51 . Therefore, in the width direction X, the length of the partition plate 66 is shorter than the length of the first visual recognition portion 51 .

The upper and lower ends of the vertically extending partition plate 66 are open. That is, the first visual recognition part 51 and the partition plate 66 form a cylindrical shape extending vertically inside the container body 41 . The liquid contained in the container body 41 flows through the space S formed by the first visual recognition portion 51 and the partition plate 66 . This space S is part of the space within the container body 41 . Therefore, the partition plate 66 partitions the interior of the container body 41 .

When the inside of the container body 41 is viewed through the viewing portion 50, the liquid and the partition plate 66 can be viewed. At this time, a part of the partition plate 66 protrudes from the surface of the liquid inside the container main body 41 . The amount of protrusion of the partition plate 66 protruding from the liquid surface varies depending on the position of the liquid surface. Therefore, it is easy to visually recognize the remaining amount of the liquid by looking at the amount of protrusion of the partition plate 66 that protrudes from the liquid surface.

The inner peripheral surface 69 of the partition plate 66 facing the space S may be textured, for example. Light is easily reflected on the surface of the transparent material that has undergone texturing. The transparency of the inner peripheral surface 69 of the partition plate 66 is reduced by texturing. Thereby, the inner peripheral surface 69 of the partition plate 66 becomes easy to reflect light.

As shown in FIGS. 33, 34, 35, 36, 37, and 38, the partition plate 66 is positioned in the container body 41 on the surface where the visual recognition portion 50 is provided, i.e., at a position closer to the front surface 43. do. Therefore, in the container body 41 , the distance between the surface on which the visual recognition portion 50 is provided and the partition plate 66 is shorter than the distance between the surface opposite to the surface on which the visual recognition portion 50 is provided and the partition plate 66 . Specifically, in the container body 41 , the distance between the front surface 43 and the partition plate 66 is shorter than the distance between the rear surface 44 and the partition plate 66 .

When the inside of the container body 41 is viewed through the first viewing portion 51 , the remaining amount of the liquid contained in the container body 41 can be visually recognized by reflecting the light that has entered the container body 41 inside the container body 41 . In general, the intensity of light decreases as the distance from the light source increases. Therefore, the shorter the distance until the light incident from the first visual recognition portion 51 is reflected in the container body 41, the higher the intensity of the reflected light. That is, the shorter the distance until the incident light from the first visual recognition portion 51 is reflected in the container body 41, the higher the intensity of the light passing through the first visual recognition portion 51 from the inside of the container body 41 toward the outside of the container body 41. growing. Therefore, it is preferable to arrange the partition plate 66 at a position close to the visual recognition portion 50 inside the container body 41 . This makes it easier to visually recognize the liquid surface position of the liquid positioned between the partition plate 66 and the visual recognition portion 50 . As a result, it becomes easier to visually recognize the remaining amount of the liquid.

In the sixth embodiment, part of the light entering the container body 41 from the first visual recognition portion 51 is reflected by the inner peripheral surface 69 of the partition plate 66 . Therefore, by positioning the partition plate 66 closer to the front surface 43 , the liquid surface position of the liquid positioned between the partition plate 66 and the first visual recognition portion 51 , that is, the liquid positioned in the space S becomes easier to visually recognize.

The partition plate 66 may not be made of a transparent material, and may be made of another material. If the partition plate 66 is made of a material that easily reflects light, texturing on the inner peripheral surface 69 becomes unnecessary. The partition plate 66 may not be formed integrally with the first visual recognition portion 51 and may be formed separately from the first visual recognition portion 51 . In this case, the partition plate 66 is formed separately from the first visual recognition portion 51 with the part indicated by the two-dot chain line in FIG. 38 as a boundary.

Even if the partition plate 66 is made of a transparent material, the inner peripheral surface 69 may not be textured. Realistically, it is difficult to form the partition plate 66 from a material with a transmittance of 100%. Therefore, if the partition plate 66 made of a transparent material is arranged near the first visual recognition portion 51 , the inner peripheral surface 69 of the partition plate 66 reflects a considerable amount of light. By providing the partition plate 66 inside the container body 41 , the remaining amount of the liquid can be visually recognized more easily than when the partition plate 66 is not provided inside the container body 41 .

A scale 57 may be provided on the first visual recognition portion 51 . By providing the scale 57 on the first visual recognition portion 51, it becomes easier to visually recognize the remaining amount of the liquid. The scale 57 is preferably formed at a position overlapping the partition plate 66 when the container body 41 is viewed from the front.

According to the sixth embodiment, the following effects can be obtained in addition to the effects (1), (2) and (6).
(7) In the container main body 41, the partition plate is arranged near the surface where the visual recognition portion 50 is provided. Therefore, the partition plate reflects light incident from the visual recognition portion 50 at a position closer to the visual recognition portion 50 . This makes it easier to visually recognize the remaining amount of the liquid.

(Seventh embodiment)
Next, a seventh embodiment of the liquid storage container 22 will be described. In the seventh embodiment, differences from the first to sixth embodiments will be mainly described.

As shown in FIGS. 39, 40 and 41, the container body 41 of the seventh embodiment has partition plates 71. As shown in FIGS. In the seventh embodiment, only the size of the partition plate 71 is different from that of the partition plate 66 in the sixth embodiment, and the rest of the configuration is the same as in the sixth embodiment.

The partition plate 71 is located at a position closer to the first visual recognition portion 51 inside the container body 41 . The length of the partition plate 71 in the vertical direction Z is the same as the length of the first visual recognition portion 51 . The partition plate 71 has an arch shape in the width direction X. As shown in FIG. That is, the partition plate 71 is curved in a semicircular shape when viewed from above or below the container body 41 . In the width direction X, the length of the partition plate 71 is equivalent to the length of the first visual recognition portion 51 . Therefore, in the width direction X, the length of the partition plate 71 in the seventh embodiment is longer than the length of the partition plate 66 in the sixth embodiment. Accordingly, the curvature of the arch-shaped partition plate 71 in the seventh embodiment is smaller than the curvature of the arch-shaped partition plate 66 in the sixth embodiment.

The partition plate 71 is provided so as to extend from both end portions in the width direction X of the first visual recognition portion 51 . Therefore, the tubular shape formed by the first visual recognition portion 51 and the partition plate 71 forms a D shape when viewed from above or below the container body 41 .

According to the seventh embodiment, effects similar to those of the sixth embodiment can be obtained. That is, according to the seventh embodiment, effects (1), (2), (6) and (7) are obtained.
(Eighth embodiment)
Next, an eighth embodiment of the liquid storage container 22 will be described. In the eighth embodiment, differences from the first embodiment will be mainly described.

As shown in FIGS. 42, 43, 44 and 45, the container body 41 of the eighth embodiment has partition plates 73. As shown in FIGS. The partition plate 73 is positioned inside the container body 41 and is provided to extend vertically when the container body 41 is attached to the carriage 23 . The partition plate 73 partitions the interior of the container body 41 . The partition plate 73 is provided so as to extend upward from the inner bottom surface of the container body 41 .

The partition plate 73 is located at a position visible through the first visual recognition portion 51 . The partition plate 73 is positioned so as to overlap the first visual recognition portion 51 in the depth direction Y. As shown in FIG. That is, the partition plate 73 is positioned so as to overlap the first visual recognition portion 51 when the container body 41 is viewed from the front. By doing so, the partition plate 66 can be visually recognized through the first visual recognition portion 51 when the container body 41 is viewed from the front. In the eighth embodiment, the second visual recognition portion 52 and the third visual recognition portion 53 may or may not be provided.

When the inside of the container body 41 is viewed through the viewing portion 50, the liquid and the partition plate 73 can be viewed. At this time, a part of the partition plate 73 protrudes from the liquid surface in the container main body 41 . The amount of protrusion of the partition plate 73 protruding from the liquid surface varies depending on the position of the liquid surface. Therefore, it is easy to visually recognize the remaining amount of the liquid by looking at the amount of protrusion of the partition plate 73 that protrudes from the liquid surface.

When the container body 41 is viewed from the front, the liquid and the partition plate 73 can be visually recognized through the first visual recognition portion 51 . When the protrusion amount of the partition plate 73 visually recognized through the first visual recognition part 51 is small, it can be visually recognized that the liquid surface position of the liquid is high. This makes it possible to visually recognize that there is a large amount of liquid remaining.

When the protrusion amount of the partition plate 73 visually recognized through the first visual recognition part 51 is large, it can be visually recognized that the liquid surface position of the liquid is low. This makes it possible to visually recognize that the remaining amount of liquid is small. By providing the partition plate 73 in the container body 41 in this way, it is possible to easily visually recognize the remaining amount of the liquid.

The partition plate 73 is positioned in the container body 41 at a position closer to the surface where the visual recognition portion 50 is provided, that is, closer to the front surface 43 . Therefore, in the container body 41 , the distance between the surface on which the visual recognition portion 50 is provided and the partition plate 73 is shorter than the distance between the surface opposite to the surface on which the visual recognition portion 50 is provided and the partition plate 73 . Specifically, in the container body 41 , the distance between the front surface 43 and the partition plate 73 is shorter than the distance between the rear surface 44 and the partition plate 73 .

Part of the light entering the container body 41 from the first visual recognition portion 51 is reflected by the partition plate 73 . Therefore, the position of the partition plate 73 closer to the front surface 43 makes it easier to visually recognize the level of the liquid positioned between the partition plate 73 and the first visual recognition portion 51 .

The partition plate 73 of the eighth embodiment is made of, for example, a white plastic material so as to easily reflect the light incident from the first visual recognition portion 51 . This makes it easier to visually recognize the liquid surface position of the liquid positioned between the partition plate 73 and the visual recognition portion 50 .

As shown in FIGS. 42, 44 and 46, grooves 74 are formed in the partition plate 73 . FIG. 46 is an end view of section EE of FIG. 44 at FF' of FIG. 44 and G-G' of FIG. 45; The groove 74 is formed on the surface of the partition plate 73 that is closer to the visual recognition portion 50 . That is, the grooves 74 are formed on the surface of the partition plate 73 that is visually recognized through the first visual recognition portion 51 . The groove 74 is formed in the partition plate 73 so as to extend in the vertical direction Z while meandering. The shape of groove 74 may be changed arbitrarily. A plurality of grooves 74 are formed in the width direction X in the partition plate 73 . By providing the grooves 74, the liquid adhering to the partition plate 73 can easily flow downward.

When the inside of the container body 41 is viewed through the first visual recognition portion 51 , if the surface of the partition plate 73 is covered with liquid, it becomes difficult to visually recognize the protrusion amount of the partition plate 73 protruding from the liquid surface. That is, it becomes difficult to visually recognize the liquid surface position. Therefore, by providing the grooves 74 in the partition plate 73 , it is possible to prevent the liquid from remaining on the surface of the partition plate 73 . As a result, it is suppressed that the liquid surface position of the liquid becomes difficult to visually recognize. As a result, it becomes easier to visually recognize the remaining amount of the liquid.

A scale 57 may be provided on the first visual recognition portion 51 . By providing the scale 57 on the first visual recognition portion 51, it becomes easier to visually recognize the remaining amount of the liquid. The scale 57 is preferably formed at a position overlapping the partition plate 73 when the container body 41 is viewed from the front.

According to the eighth embodiment, the effects (1), (2), (6) and (7) are obtained.
(Ninth embodiment)
Next, a ninth embodiment of the liquid storage container 22 will be described. In the ninth embodiment, differences from the first to eighth embodiments will be mainly described.

The partition plate 76 is located at a position visible through the first visual recognition portion 51 . The partition plate 76 is positioned so as to overlap the first visual recognition portion 51 in the depth direction Y. As shown in FIG. That is, the partition plate 76 is positioned so as to overlap the first visual recognition portion 51 when the container body 41 is viewed from the front. By doing so, the partition plate 76 can be visually recognized through the first visual recognition portion 51 when the container body 41 is viewed from the front. In the ninth embodiment, the second visual recognition portion 52 and the third visual recognition portion 53 may or may not be provided.

The partition plate 76 is arranged in the container main body 41 at a position closer to the surface where the visual recognition portion 50 is provided, that is, the front surface 43 side. Therefore, in the container body 41 , the distance between the surface on which the visual recognition portion 50 is provided and the partition plate 76 is shorter than the distance between the surface on which the visual recognition portion 50 is provided and the surface opposite to the partition plate 76 . Specifically, in the container body 41 , the distance between the front surface 43 and the partition plate 76 is shorter than the distance between the rear surface 44 and the partition plate 76 .

In the ninth embodiment, part of the light entering the container body 41 from the first visual recognition portion 51 is reflected by the partition plate 76 . Therefore, the position of the partition plate 76 closer to the front surface 43 makes it easier to visually recognize the level of the liquid positioned between the partition plate 76 and the first visual recognition portion 51 .

The partition plate 76 is formed so that the length in the vertical direction Z is shorter than the length in the width direction X. As shown in FIG. Therefore, when the inside of the container body 41 is viewed through the first viewing portion 51 , the partition plate 76 may not protrude from the liquid surface depending on the remaining amount of liquid contained in the container body 41 .

The upper end of the partition plate 76 protrudes from the liquid surface when the remaining amount of the liquid contained in the container body 41 becomes small. The partition plate 76 can be visually recognized when the liquid surface position of the liquid falls below the position of the upper end of the partition plate 76 . That is, when the partition plate 76 is visible through the first visual recognition portion 51, it can be visually recognized that the remaining amount of the liquid is low. If the partition plate 76 cannot be visually recognized, it can be visually recognized that the remaining amount of liquid is large.

According to the ninth embodiment, the effects (1), (2), (6) and (7) are obtained.

The scale band 78 may be positioned closer to the right side surface 47 in the first visual recognition portion 51 . The scale band 78 may be attached to either the surface forming the front surface 13 (surface 67 ) or the surface located inside the container body 41 (back surface 68 ) in the first visual recognition portion 51 .

The scale band 78 has a rectangular shape extending in the vertical direction Z. As shown in FIG. The length of the scale band 78 in the vertical direction Z is substantially the same as the length of the first visual recognition portion 51 . In the width direction X, the length of the scale band 78 is shorter than the length of the first visual recognition portion 51 . In the tenth embodiment, the second visual recognition portion 52 and the third visual recognition portion 53 may or may not be provided. The scale band 78 may be attached to a region of the front surface 43 excluding the first visual recognition portion 51 . In this case, it is preferable that the scale band 78 is positioned so as to be adjacent to the first visual recognition portion 51 in the width direction X. As shown in FIG. For example, the scale band 78 may be located at the position indicated by the two-dot chain line in FIG.

When viewing the liquid surface position of the liquid through the first visual recognition portion 51 , it is easy to visually recognize the remaining amount of the liquid by also viewing the scale band 78 .
