  2. Description of the Related Art Conventionally, there has been known a liquid container that is detachably mounted on a carriage that reciprocates by mounting a liquid ejecting head in a liquid ejecting apparatus. As one of these liquid containers, a movable projection is provided on one side of the wall that intersects the direction of movement when attaching and detaching, and a fixed projection is formed to project from the other side of the wall. I have something to do. In this liquid container, the movable protrusion is locked to a part of a rotating lever provided on one side of the carriage, and the fixed protrusion is inserted into an engagement hole formed on the other side of the carriage. By being locked, the carriage is mounted in a state in which the upward movement from the carriage is restricted (see, for example, Patent Document 1).

Japanese Patent Laid-Open No. 2006-107620

  By the way, when mounting the liquid container having projections on the wall portions on one side and the other side onto the carriage, the liquid container is placed in an inclined posture with the other side having the fixed protrusions lowered, and the tips of the fixed protrusions After being inserted into the engagement hole, it is mounted by a so-called rotational mounting method in which one side of the movable projection is lowered from the inclined position to a horizontal position.

  However, in such a rotation mounting method, the tip of the fixing projection protruding obliquely downward from the wall portion on the other side of the inclined liquid container is aligned and inserted into the engagement hole provided on the carriage from obliquely upward. However, since it is rotated from that state to a horizontal posture, the operation is troublesome.

  The present invention has been made in view of such circumstances, and its purpose is to easily attach even when the wall on one side and the wall on the other side have projections in the direction intersecting with the direction of movement during attachment / detachment. An object of the present invention is to provide a liquid container that can be used.

Hereinafter, means for solving the above-described problems and the effects thereof will be described.
The liquid container that solves the above problems is
A mounting portion to which the liquid container can be attached and detached, and a head that ejects the liquid supplied from the liquid container attached to the mounting portion, and the liquid container moves at the time of attachment and detachment in the mounting portion. On the first side wall located on one side in the X direction, which is the direction intersecting the vertical direction, there is a first engaged portion capable of engaging a part of the liquid container mounted on the mounting portion. A liquid provided with a second engaged portion that can be engaged with a part of the liquid container mounted on the mounting portion on a second side wall located on the other side in the X direction. A liquid container detachably attached to the mounting portion in the ejection device, wherein the first wall faces the first side wall in the X direction when the mounting portion is mounted with the liquid container. And a second wall portion facing the second side wall in the X direction The liquid container is provided on the main body portion and the first wall portion, and is engaged with the first engaged portion in the mounted state, so that the liquid container moves in a direction to be removed from the mounting portion. A direction in which the liquid container is removed from the mounting portion by being provided on the second wall portion that can be regulated and engaging with the second engaged portion in the mounting state. A second protrusion capable of restricting movement to at least one of the first protrusion and the second protrusion is urged from the inside to the outside of the main body. In conjunction with the attachment / detachment operation of the liquid container with respect to the mounting part, the liquid container is configured to be movable between a position protruding outside the main body part and a position immersing inside the main body part.

  According to this configuration, when the liquid container is mounted on the mounting portion, the first protrusion and the second side wall with respect to the first side wall in the X direction that intersects the vertical direction. On the other hand, the second protrusions are aligned with each other and moved from the state toward the mounting portion vertically below without rotating the posture of the main body. Then, during the movement, the liquid container has the first and second protrusions that are biased from the inside to the outside of the main body and are aligned with the protrusions in the X direction. While sliding on the side wall, it moves between a position protruding outside the main body and a position immersed inside the main body. Then, when the biased protrusion is in a position facing the engaged portion in the X direction, the liquid container is mounted because it protrudes based on the biasing force and automatically engages the engaged portion. The movement in the direction to be removed from the part is restricted. Therefore, the liquid container can be easily mounted even when the one side wall portion and the other side wall portion have projections in the direction intersecting with the direction of movement during attachment / detachment.

  Further, in the liquid container, the lower surface of the first protrusion and the second protrusion that are biased from the inner side to the outer side of the main body portion is directed toward the tip of the protrusion. It is preferable that an ascending slope or curved surface is provided.

  According to this configuration, when the liquid container is moved vertically downward in order to mount the liquid container in the mounting portion, the projection that was biased from the inside of the main body portion toward the outside and protruded from the main body portion is The liquid container can be smoothly mounted in the mounting portion because the inclined surface or curved surface having an upward slope toward the tip of the lower surface is slid into the inside of the main body while sliding on a part of the side wall located below.

  Further, in the liquid container, an upper surface of the first protrusion and the second protrusion that are biased from the inside to the outside of the main body portion is directed toward the tip of the protrusion. It is preferable that a slope or curved surface with a downward slope is provided.

  According to this configuration, when the liquid container is lifted vertically to remove the liquid container from the mounting portion, the protrusion that is biased from the inside of the main body portion to the outside and engaged with the engaged portion is The liquid container can be smoothly removed from the mounting portion because the inclined surface or curved surface having a downward slope toward the tip of the upper surface is slid into the engaged portion while sliding on the engaged portion.

  In addition, the liquid container is disposed in the mounting portion so as to descend from vertically above, and then slides in the Y direction, which is a direction intersecting both the vertical direction and the X direction. On the other hand, the liquid can be supplied to the head, and the tip of the first protrusion and the second protrusion, which is biased from the inside to the outside of the main body, is attached to the head. It is preferable that a hook portion that protrudes in the Y direction so as to be locked with respect to the engaged portion with which the protrusion is engaged is provided.

  According to this configuration, in the liquid container that is slid in the Y direction after being disposed in the mounting portion, the hook portion of the protrusion that is engaged with the engaged portion is in the X direction with respect to the engaged portion. Therefore, it is possible to reduce the possibility that the liquid container is unintentionally removed from the mounting portion by releasing the engagement of the protrusion with the engaged portion.

  In the liquid container, the first protrusion is a movable protrusion urged from the inside to the outside of the main body, and the hook is provided at the tip of the first protrusion. The second protrusion is a fixed protrusion protruding from the second wall portion, and does not come into contact with the second engaged portion when the liquid container is attached to or detached from the mounting portion. It is preferable that the container can be engaged when the container is slid in the Y direction after being disposed in the mounting portion.

  For example, in the case of a configuration in which the second protrusion is engaged with the second engaged portion configured by the lower end of the rotating lever after sliding over the inclined surface of the rotating lever when mounted. When the liquid container is removed from the mounting portion, it is necessary to operate the rotation lever. In this regard, according to the above configuration, the second protrusion does not come into contact with the second engaged portion during attachment / detachment, so that such an operation can be eliminated, and the liquid container can be easily removed from the mounting portion. Can do.

That is, the liquid container 28 is divided into a plurality of partition walls 31 in the mounting portion 27 so that the width in the Y direction is slightly larger than the thickness (dimension in the Y direction) of each liquid container 28. The mounting region 32 is disposed above the mounting region 32 where the liquid container 28 is to be mounted. In this case, in the liquid container 28, the first protrusion 70 is aligned with the −X direction side where the first side wall 57 is located, and the first X side is located on the + X direction side where the second side wall 58 is located. Two protrusions 69 are aligned.

  In this case, the liquid container 28 is arranged in a horizontal posture in which the + Z direction side wall portion 41 and the −Z direction side wall portion 42 are along the X direction without tilting the posture. As shown in FIG. 8, the liquid container 28 includes a main body 28 a having a slope 70 b on the lower surface of the first protrusion 70 that protrudes from the main body 28 a toward the −X direction and the upper end of the first side wall 57. The second protrusion 69 protruding in the + X direction side from the portion 28a is arranged so as to be displaced from the rotation lever 33 in the Y direction. From that state, the liquid container 28 held by the user is moved vertically downward while maintaining the horizontal posture.

  Then, as shown in FIGS. 9 and 10, the liquid container 28 has the first protrusion 70 that slides the inclined surface 70 b on the lower surface to the upper end of the first side wall 57, thereby attaching the urging member 56. It begins to immerse inside the main body portion 28a against the force, and further moves to immerse inside the main body portion 28a by sliding the tip portion on the guide surface 53 on the inner surface of the first side wall 57. . Then, when the liquid container 28 is further moved vertically downward from the state, the first protrusion 70 faces the first engaged portion 65 formed on the first side wall 57 in the X direction. become. Then, the first protrusion 70 protrudes to the outside of the main body portion 28a based on the urging force of the urging member 56, and the tip end portion is automatically inserted into the hole-shaped first engaged portion 65 as shown in FIG. And is brought into contact with and engaged with the first engaged portion 65 from the −Z direction side.

  As shown in FIG. 11, in this case, the hook portion 55 formed at the tip of the first protrusion 70 has not yet engaged with the hole edge of the first engaged portion 65. Further, the second protrusion 69 remains displaced in the + Y direction with respect to the rotation lever 33 in the Y direction. Therefore, the second protrusion 69 does not contact the rotation lever 33 when moving in the vertical direction for attachment / detachment, and the second engaged portion 33b at the lower end of the rotation lever 33 in the vertical direction when mounted. It moves to the position which becomes lower than. At this time, the liquid supply part 47 of the side wall part 42 in the −Z direction of the liquid container 28 is displaced in the + Y direction with respect to the liquid introduction part 38 of the mounting part 27, so The liquid is not ready to be supplied to the head 25. Therefore, the liquid container 28 is further moved in the −Y direction from the state shown in FIG.

  Then, as shown in FIG. 12, the first protrusion 70 that is in contact with and engaged with the first engaged portion 65 from the −Z direction side has the hook portion 55 at the tip end of the first projection 70. It is possible to restrict the liquid container 28 from moving to the + X direction and being detached from the mounting portion 27 by being locked to the hole edge of the first engaged portion 65. Further, the second protrusion 69 moves to a position immediately below the second engaged portion 33b at the lower end of the rotation lever 33, and comes into contact with the second engaged portion 33b from the −Z direction side. Engage. As a result, the liquid container 28 has the first protrusion 70 engaged with the first engaged portion 65 and the second protrusion 69 engaged with the second engaged portion 33b. The movement in the + Z direction is restricted. Then, the liquid container 28 is in an appropriate mounting state in which the liquid supply unit 47 can supply the liquid in the liquid storage chamber 59 to the head 25 with respect to the liquid introduction unit 38 in the mounting unit 27.

On the other hand, as shown in FIGS. 13 and 14, when removing the liquid container 28 from the mounting portion 27, the user first slides the liquid container 28 in the + Y direction.
Then, in the liquid container 28, the hook portion 55 of the first protrusion 70 is released from the locked state with respect to the hole edge of the first engaged portion 65, while the second protrusion 69 is turned on the rotating lever 33. The position is shifted in the + Y direction from the position directly below the second engaged portion 33b. Then, from this state, as shown in FIG. 14, the liquid container 28 is slightly displaced in the + X direction and then moved vertically upward while maintaining its horizontal posture.

  Then, the liquid container 28 resists the urging force of the urging member 56 by causing the first protrusion 70 to slide the slope 70 a on the upper surface to the hole edge of the hole-shaped first engaged portion 65. Then, it begins to immerse inside the main body portion 28a, and further, the tip portion slides on the inner surface of the first side wall 57, thereby moving further to immerse inside the main body portion 28a. When the liquid container 28 is further moved vertically upward from that state, the first protrusion 70 is released from the contact state with the first side wall 57, and the liquid container 28 is allowed to move in the + Z direction. Therefore, it can be easily detached from the mounting portion 27.

According to the above embodiment, the following effects can be obtained.
(1) When mounting the liquid container 28 on the mounting portion 27, the liquid protrusion 28 is positioned above the mounting portion 27 and the first protrusion 70 is positioned on the −X direction side where the first side wall 57 is positioned. After being arranged in a horizontal position, the first protrusion 70 urged outward from the main body 28a is automatically engaged with the first engaged portion 65 simply by moving vertically downward without rotating as it is. Yes. That is, after the first protrusion 70 biased so as to protrude from the main body portion 28a is immersed inside the main body portion 28a by sliding with the first side wall 57, the first engaged portion 65 and When in the opposing position state, the liquid container 28 protrudes based on the urging force and automatically engages with the first engaged portion 65, so that the liquid container 28 is restricted from moving in the direction of being detached from the mounting portion 27. It becomes a state. Accordingly, the liquid container 28 has a first convex shape on each of the −X direction side wall portion 44 and the other side + X direction side wall portion 43 in the X direction that intersects the Z direction that moves when the mounting portion 27 is attached and detached. Even when the projection 70 and the second projection 69 are provided, they can be easily mounted without using a complicated rotational mounting method.

  (2) Further, when the liquid container 28 is moved vertically downward at the time of mounting, the first protrusion 70 that has been biased so as to protrude from the main body 28a is directed toward the tip of the lower surface. The liquid container 28 can be smoothly mounted in the mounting portion 27 because the upward inclined surface 70b is slid into a part of the first side wall 57 positioned below and immersed inside the main body portion 28a.

  (3) On the other hand, when removing the liquid container 28 from the mounting part 27, when the liquid container 28 is lifted vertically upward from the mounting part 27, the liquid container 28 is urged so as to protrude from the main body part 28a. The first protrusion 70 that has been engaged with the engaging portion 65 slides the slope 70a having a downward slope toward the tip of the upper surface of the first protrusion 70 while sliding the first engaged portion 65 on the inner side of the main body portion 28a. Immerse yourself in. Therefore, the liquid container 28 can be removed from the mounting portion 27 smoothly.

  (4) Further, the liquid container 28 that has been lowered from above the mounting portion 27 and placed in the mounting portion 27 and has been slid in the −Y direction is inserted into the hole-shaped first engaged portion 65. The hook portion 55 of the first protrusion 70 in the state of being locked is engaged with the hole edge of the first engaged portion 65 so as to restrict the movement of the liquid container 28 in the + X direction. Therefore, it is possible to reduce the possibility that the first projection 70 is disengaged from the first engaged portion 65 and the liquid container 28 is unintentionally removed from the mounting portion 27.

  (5) For example, the second protrusion 69, which is a fixed protrusion, slides over the inclined portion 33d of the rotation lever 33 and gets over the second engaged portion 33b at the lower end of the rotation lever 33. In the case of a configuration in which the liquid container 28 is detached from the mounting portion 27, it is necessary to operate the rotation lever 33. However, the second protrusion 69 in the above embodiment is unevenly distributed in the + Y direction side in the Y direction with respect to the second engaged portion 33b, and does not contact the second engaged portion 33b at the time of attachment / detachment. The operation of the rotating lever 33 can be made unnecessary, and the liquid container 28 can be easily detached from the mounting portion 27.

In addition, you may change the said embodiment as follows.
As shown in FIG. 15, the liquid container 28 may have a configuration in which the hook portion 55 is not provided at the distal end portion of the first protrusion 70 urged so as to protrude from the main body portion 28 a. In this case, it is not necessary to slide the liquid container 28 disposed in the mounting portion 27 in the Y direction. Even when configured in this way, the same effects as (1) to (3) and (5) in the above embodiment can be enjoyed.

  The liquid container 28 may be configured such that the hook portion 55 protrudes in the + Y direction from the distal end portion of the first protrusion 70 biased so as to protrude from the main body portion 28a. . In this case, the liquid container 28 disposed while being lowered in the mounting portion 27 is slid in the + Y direction. Even when configured in this manner, the same effects as in (4) and (5) in the above embodiment can be enjoyed.

  When the liquid container 28 is mounted on the mounting portion 27, the second protrusion 69 slides on the inclined portion 33 d of the rotation lever 33 from the upper side to the lower side and climbs over the lower end of the rotation lever 33 to the lower side. The structure which engages with the to-be-engaged part 33b of 2 may be sufficient. Even when configured in this way, the same effects as (1) to (3) in the above embodiment can be enjoyed.

  The liquid container 28 is not provided with a slope 70a having a downward slope on the top surface of the first protrusion 70 biased so as to protrude from the main body 28a toward the tip of the first protrusion 70. Also good. Even in such a configuration, the liquid container 28 can be smoothly removed from the mounting portion 27 as long as an oblique guide surface is provided at the hole edge of the first engaged portion 65 in the first side wall 57. be able to.

  The liquid container 28 is not provided with a slope 70b having an upward slope toward the tip of the first protrusion 70 on the lower surface of the first protrusion 70 biased so as to protrude from the main body 28a. Also good. Even in such a configuration, the liquid container 28 can be easily mounted on the mounting portion 27 as long as the oblique guide surface 53 is provided on the inner surface of the first side wall 57.

  The first engaged portion 65 is limited to a hole shape as long as the first protrusion 70 having a convex shape has an engagement surface along the X direction that can be engaged by being brought into contact with the −Z direction. Not. In other words, the inner surface of the first side wall 57 of the mounting portion 27 may be formed to have a step shape or a concave shape. Or the structure which made the convex part shape which protruded in the + X direction side from the inner surface of the 1st side wall 57 of the mounting part 27, and the lower surface was made into the engagement surface along a X direction may be sufficient. Even in such a configuration, it is possible to engage the first projection 70 having a convex shape from the −Z direction side by contact.

  The second engaged portion 33 b may be configured other than the lower end portion of the rotation lever 33. For example, as in the case of the first engaged portion 65, a hole-shaped second engaged portion 33 b may be provided on the second side wall 58. In this case, the rotation lever 33 may not be provided on the mounting portion 27.

  As in the case of the first protrusion 70, the second protrusion 69 may also be composed of a movable protrusion that is biased so as to protrude from the main body 28 a instead of the fixed protrusion. In this case, a hook portion protruding in the Y direction from the tip end portion of the second protrusion 69 may be provided.

  The first protrusion 70 may be a fixed protrusion, and the second protrusion 69 may be a movable protrusion that is urged by the urging member 56 so as to protrude from the main body 28a. In this case, it is preferable that the second engaged portion with which the second protrusion 69 is engaged has a hole shape.

  The urging member 56 that urges the first protrusion 70 in the direction of projecting to the outside of the main body 28a is not limited to a coil spring, and may be a leaf spring, a bamboo shoot spring, or an elastic sponge member. .
