## Background
BACKGROUND
1. Technical Field
The present invention relates to a liquid ejecting apparatus capable of ejecting liquid supplied from a liquid container.
2. Related Art
In recent years, an ink-jet type printer (hereinafter, simply referred to as a printer) which performs printing by ejecting ink accommodated in an ink cartridge onto a medium, such as a paper sheet, has been known as a liquid ejecting apparatus capable of ejecting liquid.
In such a printer, the ink cartridge is detachably mounted in a casing body. Therefore, replenishment of ink is generally carried out by replacing the ink cartridge with a new one.
However, it is necessary for the ink cartridge to have a size enabling it to be accommodated in the casing body, and therefore it is difficult to increase the size of the ink cartridge. Thus, when a large quantity of printing is conducted, it is necessary to interrupt the printing and perform a replacement each time the ink in the ink cartridge runs out.
In order to reduce the frequency of the replacement of an ink cartridge, a printer has been disclosed in which the replenishment of ink is conducted by injecting ink from an ink pack provided outside a casing body into an ink cartridge mounted to the casing body, via an ink tube (see JP-A-2009-202346, for example).
However, when the ink pack provided outside the casing body is connected with the casing body of the printer, there is a possibility that the ink pack may be disconnected from the casing body by a collision between the ink pack or the ink tube and a person, an object or the like. Further, when the ink pack is disconnected from the casing body, there is a problem in that supplying ink is not possible or the ink leaks out.
Such a problem is not limited to a printer in which ink is supplied from an ink pack provided outside a casing body but is generally common to a liquid ejecting apparatus equipped with a liquid container which is mounted in a state where at least a part thereof is exposed to the outside of a casing body.
SUMMARY
An advantage of some aspects of the invention is to provide a liquid ejecting apparatus in which the influence of an external force on a liquid container can be suppressed.
Hereinafter, means for solving the problem described above and operation effects thereof will be described.
According to an aspect of the invention, there is provided a liquid ejecting apparatus including: a liquid ejecting portion capable of ejecting liquid; a casing body for accommodating the liquid ejecting portion; a liquid container which is mounted on the casing body in a state where at least a part thereof is exposed to the outside of the casing body; and a protecting portion which protects a part of the liquid container exposed to the outside of the casing body from an external force.
According to the configuration described above, the external force acting on a part of the liquid container exposed to the outside of the casing body is reduced by the protecting portion. Therefore, it is possible to suppress the influence of an external force on the liquid container.
In the liquid ejecting apparatus, it is preferable that a space be provided between a part of the liquid container exposed to the outside of the casing body and the protecting portion.
According to the configuration described above, a space is provided between a part of the liquid container exposed to the outside of the casing body and the protecting portion. Therefore, it is difficult for the influence of the external force acting on the protecting portion to be transmitted to the liquid container. Thus, it is possible to suppress the influence of an external force on the liquid container.
It is preferable that the liquid ejecting apparatus further include a liquid supply mechanism for supplying liquid accommodated in the liquid container to the liquid ejecting portion. Further, the liquid container may have a connecting portion which is connected with the liquid supply mechanism in the casing body, and a protruding portion which protrudes from the casing body and constitutes a part of the liquid container exposed to the outside of the casing body. In addition, a container support portion for supporting the protruding portion may be provided in the casing body.
According to the configuration described above, the protruding portion of the liquid container is supported by the container support portion. Therefore, the displacement of the connecting portion is suppressed even when an external force acts on the protruding portion. Thus, it is possible to maintain a favorable connecting state between the liquid container and the liquid supply mechanism.
In the liquid ejecting apparatus, it is preferable that the protruding portion of the liquid container protrude from the casing body in a protruding direction intersecting an up-down direction, and the container support portion have an adjustment mechanism for adjusting a position of the protruding portion in the up-down direction.
According to the configuration described above, it is possible to adjust the position of the protruding portion in the up-down direction by the adjustment mechanism so that the protruding portion side of the liquid container is not lowered than the connecting portion side. Therefore, the displacement of the connecting portion caused by the leaning of the liquid container is suppressed. Thus, it is possible to maintain a favorable connecting state between the liquid container and the liquid supply mechanism.
In the liquid ejecting apparatus, it is preferable that the protecting portion have a pair of side walls which are aligned in a width direction intersecting both the up-down direction and the protruding direction so as to interpose the protruding portion of the liquid container therebetween.
According to the configuration described above, an external force acting on the protruding portion of the liquid container is reduced by the side walls of the protecting portion. Therefore, it is possible to suppress the influence of an external force on the liquid container.
In the liquid ejecting apparatus, it is preferable that an injection port for liquid be provided in the protruding portion of the liquid container, and the protecting portion have a plate-shaped liquid reception portion which is disposed on a lower side of the protruding portion in a state of being inclined so as to be gradually lowered from the casing body side in the protruding direction.
According to the configuration described above, the external force acting on the protruding portion of the liquid container is reduced by the liquid reception portion. Therefore, it is possible to suppress the influence of the external force on the liquid container. Furthermore, when liquid leaks out at the time of injecting the liquid into the liquid container through the injection port, the leaked liquid is received by the liquid reception portion disposed on the lower side of the protruding portion. Therefore, it is possible to suppress contamination by the liquid leaked at the time of injection. Furthermore, the liquid reception portion is disposed in a state of being inclined so as to be gradually lowered from the casing body side in the protruding direction, and therefore the received liquid is collected in the lower end side of the liquid reception portion. Thus, it is easy to remove the leaked liquid.
In the liquid ejecting apparatus, it is preferable that a liquid storage portion capable of storing liquid be provided on a lower end side of the liquid reception portion.
According to the configuration described above, the liquid storage portion is provided on the lower end side of the liquid reception portion. Therefore, it is possible to store the liquid, which is received by the liquid reception portion, in the liquid storage portion. Thus, it is possible to reduce the frequency of removing the liquid leaked at the time of injection.
It is preferable that the liquid ejecting apparatus further include a leg portion which is disposed on a lower side of the casing body for supporting the casing body, and a support member which has a joining portion to be joined to the liquid reception portion at a position located closer to the casing body side than the injection port in the protruding direction, and is fixed to the leg portion to support the protecting portion.
According to the configuration described above, the support member supporting the protecting portion is fixed to the leg portion separate from the casing body. Therefore, even when an external force acts on the protecting portion, it is possible to suppress the influence of the external force on the liquid container mounted to the casing body. Furthermore, the joining portion of the support member is joined to a part of the liquid reception portion, which is located closer to the casing body side than the injection port in the protruding direction. Thus, even when a screw hole or the like used for joining is provided on the liquid reception portion, the leakage of the liquid received by the liquid reception portion is suppressed.

A plurality (four in the embodiment) of liquid containers 24 are provided corresponding to types or colors of ink. Further, the plurality of liquid containers 24 are mounted to the casing body 14 in a state of being aligned in the width direction X. The mounted liquid containers 24 constitute a liquid accommodating unit 25.
The liquid ejecting apparatus 11 includes a protecting portion 26 which surrounds the liquid accommodating unit 25 for protecting the liquid container 24. Furthermore, the protecting portion 26 is disposed so as to provide a space between the protecting portion 26 and the liquid container 24. In addition, a waste liquid tank 27 is fixed to one (a right side one in FIG. 1) of the leg portions 13.
A roll body R1 which is an unused paper sheet S wound in a cylindrical shape is held in the feeding portion 15, as shown in FIG. 2. In addition, a pair of transporting rollers 28, which transports the paper sheet S sent from the feeding portion 15, and a carriage 29, which reciprocates in a main scanning direction (the width direction X in the embodiment) perpendicular to the transporting direction of the paper sheet S is accommodated in the casing body 14. Furthermore, a liquid ejecting portion 30 capable of ejecting ink is held on the lower portion of the carriage 29.
In the liquid container 24, an end portion on a base end side (a rear end side in the embodiment) accommodated in the casing body 14 is connected to a liquid supply mechanism 31 for supplying ink to the liquid ejecting portion 30. Furthermore, recording (printing) is carried out by causing the liquid ejecting portion 30 to eject the ink supplied from the liquid container 24 onto the paper sheet S transported along the transporting path.
In addition, heaters 17a for drying the ink adhered to the paper sheet S are provided on a rear side of the support member 17. Further, the printed paper sheet S is guided obliquely downward along the support member 17. Then the printed paper sheet S is wound by the winding portion 16 and forms a roll body R2.
The liquid container 24 includes a liquid accommodating body 32 in which an accommodation chamber 24a for accommodating ink is formed, and a slider 33 moving slidably in the front-rear direction Y along an upper surface of the liquid accommodating body 32, as shown in FIG. 3.
In the slider 33, a part thereof on a front end side forms a pivot type lid portion 33a. The lid portion 33a of the slider 33 moves from a closed position shown by a two-dot chain line in FIG. 3 to an opened position shown by a solid line by pivoting upwardly.
When the lid portion 33a of the slider 33 is disposed at the closed position, an injection recess portion 34 which is formed on an upper surface side of the liquid accommodating body 32 and an injection port 35 which is formed on an inner bottom portion of the injection recess portion 34 and used to inject ink are exposed. In addition, the injection port 35 communicates with the accommodation chamber 24a. 
When refilling the liquid container 24 with ink, ink accommodated in a refilling container BT having a pouring port SP is injected through the injection port 35. Further, an opening size of the pouring port SP of the refilling container BT is set to be 20% to 80% of an opening size of the injection port 35.
The liquid accommodating body 32 has a base end portion 32a accommodated in the casing body 14 and a protruding portion 32b. The protruding portion 32b protrudes from the casing body 14 in a protruding direction (a front direction in the embodiment) intersecting the up-down direction Z. Furthermore, in the liquid accommodating body 32, a connecting portion 32c which is connected with the liquid supply mechanism 31 in the casing body 14 so as to enable ink to be supplied is provided in the base end portion 32a. In addition, a bottom portion of the base end portion 32a of the liquid container 24 is supported inside the casing body 14.
The protruding portion 32b of the liquid accommodating body 32 extends downward further than the base end portion 32a. Further, a bottom portion of the protruding portion 32b in the liquid container 24 is disposed at a position located further downward than a bottom portion of the casing body 14. Additionally, in the liquid accommodating body 32, a stepped bottom portion 36 is formed on a lower portion of a rear side of the protruding portion 32b. Further, a screw fastening projection portion 37 projects from the lower end portion of the protruding portion 32b in the liquid accommodating body 32. Specifically, the screw fastening projection portion 37 is positioned on the front side of the stepped bottom portion 36 in the front-rear direction Y.
The protruding portion 32b of the liquid accommodating body 32 is supported by a container support portion 38 provided in the casing body 14. The container support portion 38 includes a fixing member 39 and a placing member 40 installed on a tip side of the fixing member 39. A base end side, namely a rear end side, of the fixing member 39 is fixed to a lower surface side of the casing body 14.
The placing member 40 has a screw fastening portion 42 which is positioned on the front end side and extends in the up-down direction Z and the width direction X, a placing portion 43 which intersects the upper end side of the screw fastening portion 42 and extends in the width direction X and the front-rear direction Y, and a pair of side wall portions 44 which intersects end portions of the screw fastening portion 42 in the width direction X.
The stepped bottom portion 36 of the liquid accommodating body 32 is placed on the placing portion 43 of the placing member 40. Then, the liquid accommodating body 32 is fixed to the casing body 14 by screwing the screw fastening projection portion 37 to the screw fastening portion 42 of the placing member 40 using a screw C1. Further, the protruding portion 32b side of the liquid container 24 is supported by the container support portion 38. In other words, a part of the liquid container 24 on the base end portion 32a side is supported inside the casing body 14, and a part of the liquid container 24 on the protruding portion 32b side is supported outside the casing body 14.
A plurality of (four in the embodiment) screw fastening holes 42a for fastening the screws C1 are formed on the screw fastening portion 42 of the placing member 40, as shown in FIG. 4. In addition, screw holes 44a are respectively formed on both side wall portions 44. Furthermore, a space is provided between the side wall portion 44 of the placing member 40 and the placing portion 43, in the up-down direction Z. Further, the placing portion 43 protrudes more than the screw fastening portion 42, in the width direction X.
As shown in FIG. 5, a pair of support side walls 39a is provided on a tip side of the fixing member 39 so as to face each other. In addition, insertion holes 39b are respectively formed on both support side walls 39a. 
As shown in FIG. 6, the placing member 40 is combined with the fixing member 39 such that the placing portion 43 is disposed above the support side walls 39a of the fixing member 39 and the pair of side wall portions 44 is disposed inside the pair of support side walls 39a of the fixing member 39. Then, the placing member 40 is screwed to the fixing member 39 by a screw C2 and a washer Wa. The screw C2 is inserted into a screw hole 44a of the placing member 40 and the insertion hole 39b of the fixing member 39.
At this time, a pair of adjusting members 45 is installed on the container support portion 38 by the screw C2. The adjusting member 45 has a first adjustment portion 46 and a second adjustment portion 47 which have a plate shape and intersect (perpendicularly, in the embodiment) each other. Subsequently, the first adjustment portion 46 or the second adjustment portion 47 of the adjusting member 45 is interposed between the support side wall 39a of the fixing member 39 and the placing portion 43 of the placing member 40. Thus, the position (a height) of the placing portion 43 is adjusted.
Furthermore, when the adjusting member 45 is installed as shown in FIG. 6, it is considered that the placing portion 43 is disposed at a reference position. Further, the adjusting member 45 and the washer Wa are not included in FIG. 3 to place more focus on the configuration of the fixing member 39.
A first insertion hole 46a is formed on the first adjustment portion 46 of the adjusting member 45, as shown in FIG. 7. In addition, a second insertion hole 47a is formed on the second adjustment portion 47 of the adjusting member 45. Further, in the adjusting member 45, a thickness D1 of the first adjustment portion 46 is set to be greater (thicker) than a thickness D2 of the second adjustment portion 47 (D1>D2). If the thickness D1 of the first adjustment portion 46 is 8 mm, the thickness D2 of the second adjustment portion 47 can be set to 4 mm, for example.
By interposing the first adjustment portion 46 of the adjusting member 45 between the support side wall 39a and the placing portion 43, a position of the protruding portion 32b side of the liquid container 24 is raised, from the reference position shown by a two-dot chain line in FIG. 8, in the up-down direction Z as much as the thickness D1, as shown in FIG. 8. In addition, a space provided between the side wall portion 44 and the placing portion 43 of the placing member 40 is greater than the thickness D1 so as to enable the first adjustment portion 46 of the adjusting member 45 to be inserted thereto.
By interposing the second adjustment portion 47 of the adjusting member 45 between the support side wall 39a and the placing portion 43, a position of the protruding portion 32b side of the liquid container 24 is raised, from the reference position shown by a two-dot chain line in FIG. 9, in the up-down direction Z as much as the thickness D2, as shown in FIG. 9.
When the adjusting member 45 is placed at the reference position, the adjusting member 45 is not disposed between the support side wall 39a of the fixing member 39 and the placing portion 43 of the placing member 40. In this case, the adjusting member 45 is simply installed on the container support portion 38, as shown by two-dot chain lines in FIGS. 8 and 9. Therefore, by changing the position of the adjusting member 45 so as to change the height of the placing portion 43, the height of the front end side of the liquid container 24 which is placed on the placing portion 43 is adjusted in plural stages (three stages in which the distance from the reference position is 0 mm, 4 mm or 8 mm are provided in the embodiment). As described above, the fixing member 39, the placing member 40 and the adjusting member 45 constitute an adjustment mechanism for adjusting the position of the protruding portion 32b in the up-down direction.
Next, a configuration of the protecting portion 26 will be described in detail.
As shown in FIG. 10, the protecting portion 26 is supported by one (a right-side leg portion in FIG. 10) of the leg portions 13 via a support unit 48 as an example of the support member. Furthermore, the protecting portion 26 has a liquid reception portion 49 having a plate shape and a pair of side walls 50 which extends upwardly from both end portions of the liquid reception portion 49 in the width direction X.
The liquid reception portion 49 is disposed on a lower side of the protruding portion 32b, which is a part of the liquid container 24. The liquid reception portion 49 is inclined so as to be gradually lowered from the casing body 14 side toward the front side (in the protruding direction). Further, the pair of side walls 50 is aligned in the width direction X so as to interpose the protruding portion 32b of the liquid accommodating body 32 therebetween. In addition, the protecting portion 26 has a reinforcing member 51 which connects front end sides of the pair of side walls 50.
In the liquid reception portion 49, an inclined surface 49a, which is an example of an inclined portion and inclined downward, is provided on an upper surface side. In addition, a wall portion 49b erected upwardly is provided on the front end side of the liquid reception portion 49. Furthermore, in the front end side of the liquid reception portion 49, notched portions 49c are respectively formed on both end sides thereof in the width direction X. Additionally, in a portion which is the lower end side of the liquid reception portion 49 and the lower end side of the protecting portion 26, a liquid storage member 52 constituting a liquid storage portion capable of storing ink is provided on a lower side of the notched portion 49c. 
The liquid storage member 52 has a bottom wall portion 52a, a side wall portion 52b and a mounting portion 52c intersecting the side wall portion 52b. Further, in a state where the bottom wall portion 52a is disposed on a lower side of the notched portion 49c, the mounting portion 52c of the liquid storage member 52 is fixed to the wall portion 49b of the protecting portion 26 and one of the side walls 50.
The bottom wall portion 52a of the liquid storage member 52 has a plate shape and intersects the side wall portion 52b and a lower end side of the mounting portion 52c, as shown in FIG. 11. Further, a recess portion surrounded by the bottom wall portion 52a, the side wall portion 52b and the mounting portion 52c is formed on the liquid storage member 52. The recess portion can store ink.
The support unit 48 includes a fixing plate 53 fixed to the leg portion 13, a pair of joining members 54 of which base end sides are fixed to the fixing plate 53, and a reinforcing plate 55 connecting the pair of joining members 54, as shown in FIG. 12. In addition, joining portions 54a are respectively formed on upper portions of both joining members 54.
In the liquid reception portion 49 of the protecting portion 26, a pair of notched portions 49c is formed on a front end side, and screw holes 49d are formed on a rear end side. Furthermore, the liquid reception portion 49 of the protecting portion 26 is fixed to the joining portion 54a of the joining member 54 by a screw C3 inserted into the screw hole 49d. 
Next, an operation of the liquid ejecting apparatus 11 configured as described above will be described.
The liquid container 24 of which the protruding portion 32b is exposed to the outside of the casing body 14 is connected with the liquid supply mechanism 31, as shown in FIG. 3. However, a part of the liquid container 24 exposed to the outside of the casing body 14 is surrounded by the protecting portion 26. Therefore, the liquid container 24 is protected from an external force by the protecting portion 26. In addition, the protecting portion 26 is fixed to the leg portion 13 separate from the casing body 14 and is disposed so as to interpose a space between the protecting portion 26 and the protruding portion 32b of the liquid container 24. Therefore, it is possible to suppress the influence of an external force on the liquid container 24 even when a person or an object collides with the protecting portion 26.
Particularly, since the leg portion 13 for supporting the casing body 14 is disposed on the lower side of the casing body 14 and the liquid container 24 is provided on the lower portion of the casing body 14, there is possibility that the protruding portion 32b may collide with the knee of a person, a bag carried by a person or the like. Furthermore, in the liquid container 24, the width direction X is a short direction. Therefore, when an external force acts on the protruding portion 32b from the lateral direction, the front end side of the liquid container 24 may pivot in the width direction X. Thus, there is a possibility that a connection failure may be caused between the liquid supply mechanism 31 and the connecting portion 32c positioned on the rear end side of the liquid container 24. However, since the protecting portion 26 has the side wall 50, the collision impact is absorbed by the side wall 50 instead of the protruding portion 32b. Therefore, it is possible to suppress the influence of an external force, which is applied from the lateral direction, on the liquid container 24.
Further, although the protecting portion 26 does not surround the upper side of the liquid container 24, the lower end side of the protruding portion 32b of the liquid container 24 is supported by the container support portion 38. Therefore, the displacement of the protruding portion 32b is suppressed even when an external force acts on the protruding portion 32b from the upper side.
Further, when the liquid container 24 is incompletely fixed to the container support portion 38, there is a possibility that the liquid container 24 may be affected greatly by an external force. However, when the adjusting member 45 is interposed between the liquid container 24 and the container support portion 38, the liquid container 24 is securely fixed to the container support portion 38, as shown in FIGS. 8 and 9. Therefore, the impact caused by the collision is suppressed. Further, the liquid container 24 is supported by the casing body 14 at two places of the inside and outside of the casing body 14. Therefore, the liquid container 24 is more firmly mounted to the casing body 14.
Furthermore, in the liquid container 24, the front-rear direction Y is a longitudinal direction, as shown in FIG. 3. Also, in the up-down direction Z, a length of the protruding portion 32b protruding from the casing body 14 is longer than a length of the base end portion 32a accommodated in the casing body 14. In other words, the amount of ink accommodated in the protruding portion 32b of the liquid container 24 is larger than the amount in the base end portion 32a thereof. Therefore, there is a possibility that the front end side may be inclined downward by the weight of the ink. However, the height of the front end side of the liquid container 24 is adjusted by the adjusting member 45. Also, the inclination of the liquid container 24 which is caused by tolerance in the design is adjusted by the adjusting member 45.
In some cases, it is possible to inject the ink in the refilling container BT into the liquid container 24. In this case, the opening size of the pouring port SP of the refilling container BT is set to be 20% to 80% of the opening size of the injection port 35, and thus the ink hardly leaks out from the injection port 35 or the injection recess portion 34, during the injection.
In addition, the liquid reception portion 49 inclined downward is disposed on a lower side of the protruding portion 32b and injection port 35 of the liquid container 24. Therefore, when the ink leaks out at the time of injecting the ink into the liquid container 24, the leaked ink is received by the liquid reception portion 49. In other words, since the protecting portion 26 which surrounds the protruding portion 32b provided with the injection port 35 is disposed between the transporting path of a paper sheet S and the injection port 35, the leaked ink is prevented from scattering around or adhering to the paper sheet S.
In addition, the ink received by the liquid reception portion 49 flows along the inclined surface 49a. Then, the ink passes through the notched portion 49c provided on the front end side of the liquid reception portion 49 and is collected in the liquid storage member 52 provided on the front side of the casing body 14. Thus, when removing the leaked ink, it is sufficient to clean only the liquid storage member 52. Therefore, it is easy to remove the leaked ink. Further, the protecting portion 26 is disposed so as to interpose a space between the protecting portion 26 and the liquid container 24. Therefore, the contamination of the liquid container 24 by the ink, which is adhered to the liquid reception portion 49 or the side wall 50 of the protecting portion 26, is suppressed.
In addition, the support unit 48 is installed on a rear-side portion of the liquid reception portion 49, which is located closer to the casing body 14 side than the injection port 35 in the front-rear direction Y (the protruding direction). In other words, the screw hole 49d of the liquid reception portion 49 is positioned at a portion which is further upward in the up-down direction Z than a part of the inclined surface 49a located just below the injection port 35. Thus, when the ink is received by the liquid reception portion 49, the ink is prevented from leaking out through the screw hole 49d provided on the liquid reception portion 49.
In addition, the protecting portion 26 is disposed between the liquid container 24 and the support member 17, as shown in FIG. 1. In other words, the heat emitted from the heater 17a is hardly transmitted to the liquid container 24 side, because the protecting portion 26 is disposed between the liquid container 24 and the heater 17a positioned on the rear side of the support member 17. Thus, the influence of heat, which is emitted from the heater 17a, on the ink in the liquid container 24 is suppressed.
According to the first embodiment described above, it is possible to achieve the following effects.
(1) The external force acting on a part (the protruding portion 32b) of the liquid container 24 exposed to the outside of the casing body 14 is reduced by the protecting portion 26. Therefore, it is possible to suppress the influence of the external force on the liquid container 24.
(2) A space is provided between the protecting portion 26 and a part (protruding portion 32b) of the liquid container 24 exposed to the outside of the casing body 14. Therefore, the liquid container 24 is hardly affected by an external force acting on the protecting portion 26. Thus, it is possible to suppress the influence of the external force on the liquid container 24.
(3) The protruding portion 32b of the liquid container 24 is supported by the container support portion 38. Therefore, the displacement of the connecting portion 32c is suppressed even when an external force acts on the protruding portion 32b. Thus, it is possible to maintain a favorable connecting state between the liquid container 24 and the liquid supply mechanism 31. As a result, the ink is prevented from leaking out through the connecting portion 32c of the liquid container 24.
(4) It is possible to adjust the position of the protruding portion 32b in the up-down direction Z by the adjusting member 45 constituting the adjustment mechanism so that the protruding portion 32b side of the liquid container 24 is not lowered than the connecting portion 32c side. Therefore, the displacement of the connecting portion 32c caused by an inclination of the liquid container 24 is suppressed. Thus, it is possible to maintain a favorable connecting state between the liquid container 24 and the liquid supply mechanism 31. As a result, the ink is prevented from leaking out through the connecting portion 32c of the liquid container 24.
(5) An external force acting on the protruding portion 32b of the liquid container 24 from the lateral direction is reduced by the side walls 50 of the protecting portion 26. Therefore, it is possible to suppress the influence of the external force on the liquid container 24.
(6) The external force acting on the protruding portion 32b of the liquid container 24 from below is reduced by the liquid reception portion 49. Therefore, it is possible to suppress the influence of an external force on the liquid container 24. Furthermore, when ink leaks out at the time of injecting the ink into the liquid container 24 through the injection port 35, the leaked ink is received by the liquid reception portion 49 disposed on the lower side of the protruding portion 32b. Therefore, it is possible to suppress contamination by the ink leaked at the time of injection. Furthermore, the liquid reception portion 49 is disposed in a state of being inclined from the casing body 14 side in the protruding direction, and therefore the received ink is collected in the lower end side of the liquid reception portion 49. Thus, it is easy to remove the leaked ink.
(7) The liquid storage member 52 is provided on the lower end side of the liquid reception portion 49 of the protecting portion 26. Therefore, it is possible to store the ink, which is received by the liquid reception portion 49, in the liquid storage member 52. Thus, it is possible to reduce the frequency of removing the ink leaked at the time of injection.
(8) The support unit 48 supporting the protecting portion 26 is fixed to the leg portion 13 separate from the casing body 14. Therefore, even when an external force acts on the protecting portion 26, it is possible to suppress the influence of the external force on the liquid container 24 mounted to the casing body 14.
(9) The joining portion 54a of the support unit 48 is joined to the rear end side of the liquid reception portion 49, which is located closer to the casing body 14 side than the injection port 35 in the protruding direction (the front-rear direction Y). Thus, even when the screw hole 49d used for joining is provided on the liquid reception portion 49, the leakage of the ink received by the liquid reception portion 49 is suppressed.
(10) The ink leaked at the time of injection is received by the liquid reception portion 49 disposed on the lower side of the injection port 35 which is provided in the liquid container 24. Therefore, it is possible to suppress the downward scattering of the ink leaked at the time of being injected into the liquid container 24.
(11) The ink received by the liquid reception portion 49 flows along the inclined surface 49a and is collected in the lower side of the liquid reception portion 49. Therefore, it is possible to easily remove the leaked ink.
(12) It is possible to store the ink, which is received by the liquid reception portion 49, flows along the inclined surface 49a and is collected, in the liquid storage member 52. Thus, it is possible to reduce the frequency of removing the leaked ink.
(13) The injection port 35 is provided in the protruding portion 32b of the liquid container 24, which is disposed outside the casing body 14. Therefore, it is possible to easily conduct the injection of ink. Furthermore, even when the ink leaks out at the time of injection, it is possible to suppress the internal contamination of the casing body 14 by the leaked ink. In addition, the liquid reception portion 49 is disposed on the lower side of the protruding portion 32b. Therefore, it is possible to receive the ink which leaks out at the time of injection and falls along the liquid container 24.
(14) It is possible to suppress the leakage of the ink at the time of injection, by stabilizing the protruding portion 32b using the container support portion 38.
(15) Since a space is provided between the liquid container 24 and the liquid reception portion 49, it is possible to suppress the adhesion of the ink, which is received by the liquid reception portion 49, to the liquid container 24.
(16) Since the protecting portion 26 is disposed between the transporting path of a paper sheet S and the injection port 35, it is possible to suppress the scattering of the leaked ink, which leaks out at the time of injection, over the transporting path of a paper sheet S. Therefore, it is possible to suppress contamination by the ink leaked at the time of being injected into the liquid container 24.
(17) Since a space is provided between the liquid container 24 and the protecting portion 26, it is possible to suppress the contamination of the liquid container 24 by the ink adhered to the protecting portion 26.
(18) Since the ink falling from the liquid container 24 at the time of injection is received by the liquid reception portion 49, the contamination is suppressed with respect to a member and the paper sheet S positioned on the lower side of the liquid container 24. Furthermore, since the ink received by the liquid reception portion 49 flows along the inclined surface and is collected in the lower side of the liquid reception portion 49, it is possible to easily remove the leaked ink.
(19) Since the protecting portion 26 surrounds the protruding portion 32b, it is possible to suppress the scattering of the ink leaked at the time of injection.

An operation panel 64 for conducting a setting operation or an input operation is provided on an upper portion of the casing body 60. Specifically, the operation panel 64 is positioned on one end side (a right end side in FIG. 13) of the upper portion in the width direction X, which is outside the transporting path of a paper sheet S. In addition, a liquid container 24 capable of accommodating ink as an example of the liquid is provided on the lower portion of the casing body 60. Specifically, the liquid container 24 is positioned on one end side (the right end side in FIG. 13) of the lower portion in the width direction X, which is outside the transporting path of a paper sheet S.
A plurality (four in the embodiment) of liquid containers 24 are provided corresponding to types or colors of ink. Further, the plurality of liquid containers 24 are mounted to the casing body 60 in a state of being aligned in the width direction X. The mounted liquid containers 24 constitute the liquid accommodating unit 25.
The liquid ejecting apparatus 11A includes the protecting portion 26 which surrounds the protruding portion 32b of the liquid container 24. Furthermore, a liquid storage portion 59 is recessed on the front end side (lower end side) of the liquid reception portion 49 of the protecting portion 26. However, the notched portion 49c and the liquid storage member 52 are not provided in the liquid reception portion 49 of the embodiment.
In addition, a carriage 65 which reciprocates in the scanning direction (the width direction X in the embodiment) perpendicular to the transporting direction of the paper sheet S is accommodated in the casing body 60. Furthermore, the liquid ejecting portion 30 capable of ejecting ink is held on the lower portion of the carriage 65. Furthermore, recording (printing) is carried out by causing the liquid ejecting portion 30 to eject the ink supplied from the liquid container 24 onto the paper sheet S.
In the lower portion of the front side of the casing body 60, a medium receiving unit 66 constituting a downstream-side part of the transporting path of a paper sheet S is installed on the leg portion 13. Further, the paper sheet S discharged from the casing body 60 through the discharging port 63 is received by the medium receiving unit 66.
Next, an operation of the liquid ejecting apparatus 11A constituted as described above will be described.
The protecting portion 26 is disposed between the injection port 35 and the medium receiving unit 66 constituting the transporting path of a paper sheet S so as to surround the protruding portion 32b of the liquid container 24 provided with the injection port 35. Therefore, the ink leaked at the time of being injected into the liquid container 24 is received by the protecting portion 26, and thus the scattering of the ink over the medium receiving unit 66 is suppressed. As a result, the contamination of the paper sheet S by the ink leaked at the time of injection is suppressed.
In addition, the ink received by the liquid reception portion 49 is collected in the liquid storage portion 59 provided on the front end side of the liquid reception portion 49. Thus, when removing the leaked ink, it is sufficient to clean only the liquid storage portion 59. Therefore, it is easy to remove the leaked ink.
According to the second embodiment described above, it is possible to achieve the following effect, in addition to the effects (1) to (19).
(20) Since the liquid storage portion 59 is recessed on the front end side of the liquid reception portion 49 of the protecting portion 26, it is possible to store the ink in the liquid storage portion 59 that has a simple configuration.
