Description

Liquid supply unit

The present invention relates to a liquid supply unit.

As a liquid supply unit that can supply a liquid to a liquid ejecting apparatus, an ink cartridge (also referred to simply as "匣") for supplying ink to a printer as an example of a liquid ejecting apparatus has been known. For example, as described in Japanese Laid-Open Patent Publication No. 2000-33707, and JP-A-2008-74100, a porous ink holding member that accommodates ink is usually housed in a sealed casing. The inside of the body is mounted on the carriage of the printer, and the ink is supplied from the ink supply hole of the bottom wall of the casing.

The enthalpy proposed in Japanese Laid-Open Patent Publication No. 2000-33707 is formed by tapering the side surface of the crucible to the bottom thereof, and the ink holding member is held so as to be compressed toward the side of the bottom wall of the casing. Thereby, the pores of the ink holding member become smaller on the side of the bottom wall of the casing, and the capillary force associated with the movement of the ink increases, so that it is preferable from the viewpoint of stable ink supply. However, the positioning of the yoke toward the bracket is performed on the side of the tapered shape, so that there is room for improvement in the positioning of the yoke along the moving direction of the yoke.

On the other hand, in the rib shape of the rib provided in the bracket as the restricting portion of the cymbal, the side surface of the cymbal is uniformly formed as a vertical surface on the bottom side thereof, as proposed in Japanese Laid-Open Patent Publication No. 2008-74100. Thereby, the positioning along the moving direction of the carriage can be improved. However, the area of the abutment with the rib as the ridge restricting portion extends over the entire area of the front and rear directions, and thus When the cymbal is mounted on the bracket, it is necessary to adopt a squatting posture along the extending direction of the rib, and there is room for improvement in the mounting property. According to the above, it is required to compress and hold the holding member of the liquid such as ink, thereby realizing the improvement of the positioning and the mountability of the crucible.

The relationship between the liquid introduction portion 710b and the like and the crucible is described below.

As shown in FIG. 7, the crucible 4 is provided with a circuit board 410 on one end side in the +Y direction. The circuit board 410 is fixed to the board mounting portion 411 that is inclined with respect to the second end wall 424. The case where the circuit board 410 is fixed to the board mounting portion 411, the arrangement position, and the like are described below. Further, the circuit board 410 provided on the crucible 4 has the following terminal 412. In a state where the crucible 8 is attached to the bracket 8, the contact portion of the terminal 412 is in electrical contact with the electrode provided in the electrode assembly 810 of the bracket 8. Further, the crucible 4 is provided with an end portion of the substrate placing portion 411 as an engaging portion 405 in the Y-axis direction in the drawing. The engaging portion 405 is engaged with the weir engaging arm 801 of the bracket 8 in a state in which the bracket 8 is attached to the bracket 8. Furthermore, the bracket 8 may also include an electrode assembly 810 and is referred to as a carrier unit.

Fig. 7 shows a state in which the cymbal 4 is attached to the bracket 8. The crucible 4 includes a supply port side liquid holding member 406 and a liquid holding member 460 having a function of absorbing and holding a liquid. The supply port side liquid holding member 406 is in contact with the liquid holding member 460.

In addition, the cymbal 5 is provided with the circuit board 510 or the like similarly to the cymbal 4, and is attached to the cradle 8 as described above.

The crucible 4 is provided with a liquid supply hole 407 which is covered by the supply hole side liquid holding member 406. The crucible mounting portion 7 is an elastic member 705 having a liquid-tight property at a base portion of the liquid introduction base portion 703. The elastic member 705 is in contact with the peripheral recessed portion 407b (see FIG. 11) around the liquid supply hole 407, and is sealed to prevent leakage of ink from the liquid supply hole 407 at the time of mounting. At the time of mounting in this manner, the liquid supply hole 407 is connected to the liquid introduction portion 710b described below to supply black ink. Further, the structure of the cymbal mounting portion 7 in which the cymbal 4 is assembled to the bracket 8 will be described later.

A cymbal mounting portion 7 is attached to the bottom of the bracket 8. As shown in FIGS. 4 to 5, the cymbal mounting portion 7 includes an inter sill protruding portion 721 extending in the Y-axis direction, a guiding protrusion portion 723, and a side wall side protruding portion 724. In FIG. 4, the side wall side protruding portion 724 is shown on the inner side of the bracket side wall 82 on the back side of the paper. However, the bracket 8 has the same configuration as the side wall side protruding portion 724 on the inner side of the bracket side wall 81 on the near side of the paper surface. The inter-turn protruding portion 721 and the side wall side protruding portion 724 extend from the end wall portion 730 of the 匣 mounting portion 7 toward the side of the 匣 engaging arm 801, and are divided in the middle.

The guide protrusion 723 extends from the end wall portion 730 toward the liquid introduction portion 710y and extends between the liquid introduction portion 710m and the liquid introduction portion 710c. In other words, the guide protrusion 723 is formed between the liquid introduction portion 710m adjacent to the X-axis direction and the liquid introduction portion 710c, and is located between the liquid introduction portion 710m and the liquid introduction portion 710c and between the liquid introduction portion 710y. . Further, in the portion of the guide protrusion portion 723 on the side of the end wall portion 730, the protruding height from the bottom surface of the mounting portion 7 is lower than the portion between the liquid introduction portion 710m and the liquid introduction portion 710c. The 匣4 is inserted into the mounting region between the side wall projecting portion 724 (not shown) on the side of the bracket side wall 81 and the inter-turning projecting portion 721, and then attached to the cymbal mounting portion 7 of the bracket 8. The 匣5 series enters between the inter-turn projection 721 and the side wall side projection 724 on the side of the bracket side wall 82. After the mounting area, it is mounted on the mounting portion 7 of the bracket 8. The guide protrusion 723 enters the following first groove 580 (see FIG. 20) of the crucible 5 attached as described above.

The cymbal mounting portion 7 is provided with a first engagement projection 741 and a second engagement projection 742. The first engagement projection 741 protrudes from the inter-turn projection 721 and the side-side projection 724 in the direction along the X-axis. For example, the first engaging projection 741 protruding from the side wall side protruding portion 724 toward the guiding projection portion 723 in the -X direction is in the mounting region of the above-described crucibles 4, 5, and the electrode assembly is located in the side wall side protruding portion 724. The 810 is further to the side of the end wall portion 730. The first engagement projection 741 that protrudes from the inter-turn projection 721 toward the guide projection 723 in the +X direction is located closer to the end wall portion 730 than the electrode assembly 810 in the inter-turn projection 721. Further, the two first engaging projections 741 are opposed to each other. In this case, in FIGS. 4 and 5, the side wall side protruding portion 724 in the mounting region of the crucible 4 and the first engaging projection 741 of the crucible protruding portion 721 are opposed to each other in the oblique direction. The first engagement projections 741 are not shown. Further, in the attachment region of the cymbal 5, the first engagement projection 741 is not shown in the yoke between the side wall-side projections 724 and the first engagement projection 741.

The second engagement projection 742 is not provided in the cymbal attachment portion 7, but is provided on the attachment base of the electrode assembly 810 provided in the bracket 8. Further, the second engagement projection 742 is attached to the attachment regions of the cymbals 4 and 5, and protrudes in the direction of the X-axis, and abuts against the cymbals 4 and 5 from the +X direction or the -X direction.

The first engaging projection 741 and the second engaging projection 742 function to position the attached arm in the X-axis direction. The first engagement projection 741 is provided in the cymbal attachment portion 7. Therefore, for example, the accuracy of the contact between the liquid introduction portion 710b provided in the crucible mounting portion 7 and the crucible 4 in the X-axis direction can be improved. On the other hand, the second engagement projection 742 is provided on the attachment base of the electrode assembly 810. Therefore, for example, the accuracy of the contact between the electrode assembly 810 and the terminal 412 of the crucible 4 in the X-axis direction can be improved. Since the cymbal mounting portion 7 is screwed to the bracket 8, an assembly error occurs between the cymbal mounting portion 7 and the bracket 8. Therefore, if only the first engagement projection 741 is used, it is difficult to improve the accuracy of the contact between the terminal 412 of the crucible 4 and the electrode assembly 810. Therefore, by using The second engaging projection 742 can improve the accuracy of the mounting of the crucible 4 to the bracket 8.

Further, the cymbal mounting portion 7 is provided with an engagement hole 750 in the end wall portion 730. The engagement hole 750 is provided for each of the 匣4 and the 匣5, and is inserted into the following engagement projections 423t and 523t when the yoke is mounted. Further, the case of the mounting or positioning of the crucible, and the relationship between the guiding protrusions 723 and the crucible 5 are described below.

The cover 401 includes an atmosphere communication hole 434 and a plurality of sealing member support seats 437 in addition to the through holes 402a, 402b, and 402c and the air groove 403. The seal member support base 437 protrudes from the upper surface of the cover 401 at the same height as the peripheral wall of the through holes 402a, 402b, and 402c or the peripheral wall of the air groove 403, and serves as an engagement support for the seal member 404.

The atmosphere communication hole 434 is formed in an outer edge of the cover portion extending in the Y-axis direction of one of the cover portions 430, and penetrates the cover 401 at the outer edge of the cover portion. Further, the atmosphere communication hole 434 is attached to the back surface of the cover 401, and is connected to the through hole 402b by an air groove (not shown). The lid rear side opening of the air groove and the atmosphere communication hole 434 and the lid back side opening of the through hole 402b are sealed by the lid back surface sealing member 436. Thereby, the recessed portion 421 of the casing 420 blocked by the cover 401 can be opened to the atmosphere through the through-hole 402a, the air groove 403, and the through-hole 402b through the atmosphere communication hole 434. The opening of the atmosphere is described in association with the liquid holding member 460.

The liquid holding member 460 is housed in the concave portion 421 of the casing 420. The bottom wall 422 of the casing 420 is provided with a stepped semicircular projection 427 around the liquid supply hole 407, and a supply hole side liquid holding member 406 is placed on the step portion of the semicircular projection 427 (refer to FIG. 7). ). Thereby, the liquid supply hole 407 is covered by the supply hole side liquid holding member 406. Further, the bottom wall 422 is provided with an arcuate projection 429 which is open in an arc shape in a plan view at the periphery of each corner portion. The liquid holding member 460 is housed in the casing 420 so as to be supported by the upper surfaces of the arcuate projections 429 and the semicircular projections 427 of the respective corners. When the liquid holding member 460 is housed as described above, the lid 401 to which the lid back surface sealing member 436 or the sealing member 404 has been joined is welded and fixed to the casing 420, and the crucible 4 shown in Fig. 7 or Fig. 8 is obtained.

A porous resin material can be used for both the supply hole side liquid holding member 406 and the liquid holding member 460. The porous resin material is not particularly limited as long as it has a function of retaining a liquid, and for example, it may be a foam member such as a urethane foam, or a polypropylene may be formed into a fiber and formed into a bundle. And the fiber components. The supply hole side liquid holding member 406 and the liquid holding member 460 are different in the characteristics for holding the liquid. The micropore density of the supply port side liquid holding member 406 indicating the density of formation of the micropores is larger than that of the liquid holding member 460. The capillary force of the supply port side liquid holding member 406 is larger than the capillary force of the liquid holding member 460 in accordance with the magnitude of the above-described micropore density.

Since the supply hole side liquid holding member 406 and the liquid holding member 460 have the above-described magnitude relationship with respect to the capillary force, the ink stored in the liquid holding member 460 flows in the order described below. That is, the ink is caused to flow from a member having a small capillary force to a member having a large capillary force. As shown in FIG. 7, when the ink accommodated in the supply-hole-side liquid holding member 406 is sucked and consumed through the liquid introduction base 703, the liquid that has been accommodated in the upper surface of the liquid-holding member 406 on the supply-hole side is held. The ink of the member 460 is moved to the supply port side liquid holding member 406. The driving force of such ink movement is mainly the capillary force of the liquid holding member 406 on the supply port side. Moreover, the air is passed through the through hole 402a corresponding to the storage position of the liquid holding member 460 and the air groove 403 connected to the through hole 402a. The atmosphere of the communication hole 434 is in communication without impeding the movement of the above ink.

As described above, the supply hole side liquid holding member 406 and the liquid holding member 460 having different characteristics are accommodated in the concave portion 421 of the casing 420, and the liquid supply member 406 has a larger capillary force than the supply hole side liquid holding member 406. The metal mesh 703s can efficiently consume the ink contained in the liquid holding member 460. That is, the remaining amount of unused ink in the liquid holding member 460 can be reduced.

In addition, as long as the capillary force of the supply-hole-side liquid holding member 406 and the liquid holding member 460 becomes smaller as it goes away from the liquid introduction base 703, the relationship between the micropore density of each of the liquid holding members 406 and 460 is It is not limited to this embodiment. For example, even when the supply hole side liquid holding member 406 and the liquid holding member 460 have the same micropore density, the liquid holding members 406 and 460 may have the above-mentioned capillary force by water-repellent treatment or hydrophilic treatment. relationship.

A-5. Installation posture:

Fig. 25 is an explanatory view schematically showing a state in which the crucibles 4 and the crucibles 5 are attached to the bracket 8. As shown in the figure, when the crucible is mounted, both the crucible 4 and the crucible 5 are inserted into the crucible mounting portion 7 of the bracket 8 in an inclined posture like the outer wall faces of the first end walls 423 and 523 facing the -Z direction. Then, the cymbals 4, 5 are in the state of maintaining the tilting posture, and as shown by the symbol A in the figure, the engaging projections 423t and 523t of the two cymbals 4 and 5 enter the cymbal mounting portion 7 of the bracket 8. The engagement hole 750 (see FIGS. 4 and 5) is pressed.

Simultaneously with the engagement projections 423t, 523t entering the engagement hole 750, the first side wall regions 425a1, 525a1 of the first side wall portions 425a, 525a of the crucibles 4, 5 and the first side wall region 426a1 of the first side wall portions 426a, 526a 526a1 is engaged with the liquid introduction part 710b, etc. Then, the first engagement projection 741 (see FIGS. 4 and 5) is disposed opposite to the side surface of the engagement hole 750 in the attachment portion 7. Thereafter, in a state where the engaging projections 423t and 523t enter the engaging hole 750, the turns 4 and 5 are swung from the inclined posture as indicated by a symbol B in Fig. 25 . During the shaking, the first side wall regions 425c1 and 525c1 of the third side wall portions 425c and 525c of the crucibles 4 and 5 and the first side wall regions 426c1 and 526c1 of the third side wall portions 426c and 526c are engaged with each other. The second engagement projection 742 (see FIGS. 4 and 5) is opposite to the side surface of the frame engagement arm 801 of the frame 8. Finally, as shown in FIG. 7, before the engagement portions 405 and 505 are engaged with the 匣 合 arm 801, the cymbals 4 and 5 are pressed against the cymbal mounting portion 7 in the -Z direction.

The fourth embodiment of the present embodiment having the above-described configuration includes a bottom wall 422 located at the bottom and a cover 401 facing the bottom wall 422 when attached to the bracket 8 of the printer 10, and the bottom wall 422 and the above The first end wall 423 and the like constitute a casing 420 (see FIG. 10 ), and the recessed portion 421 is stacked and accommodated, and includes a supply hole side liquid holding member 406 and a liquid holding member 460 . Further, as shown in FIG. 10 to FIG. 12, the first side wall 425 includes the first side wall portion 425a and the first side wall 425 in the first direction from the first end wall 423 toward the second end wall 424. The second side wall portion 425b. Further, in the crucible 4 of the present embodiment, as shown in FIGS. 13 to 14, the first side wall portion 425a is formed as a first side wall portion 425a1 having a side perpendicular to the bottom wall 422 on the side of the bottom wall 422. And the second side wall region 425a2 inclined with respect to the bottom 422 on the side of the cover 401, and the second side wall portion 425b is inclined with respect to the bottom wall 422.

As shown in FIG. 25, when the crucible 4 is attached to the bracket 8 of the printer 10, the first side wall region 425a1 substantially perpendicular to the bottom wall 422 is brought into contact with the crucible. The first engagement projection 741 of the portion 7 may be such that the second side wall portion 425b that is aligned with the first side wall portion 425a in the first direction from the first end wall 423 toward the second end wall 424 does not need to be in contact with the crucible. The first engagement projection 741 is attached to the mounting portion 7. Thereby, it is not necessary to make the entire area of the first side wall 425 abut against the top mounting portion 7 of the bracket 8 in the printer 10. As a result, according to the crucible 4 of the present embodiment, when the printer 10 is mounted, the degree of freedom of the posture of the crucible is increased, and the mountability is improved. Also, since the first sidewall region can be substantially perpendicular to the bottom wall 422 Since the 425a1 is in contact with the printer 10, the crucible 4 can be surely positioned according to the crucible 4 of the present embodiment. Further, the second side wall region 425a2 which is closer to the side of the cover 401 than the first side wall region 425a1 of the first engagement projection 741 which is in contact with the printer 10 and in detail in the cymbal attachment portion 7 And the second side wall portion 425b that is parallel to the first side wall portion 425a in the first direction is inclined with respect to the bottom wall 422. Thus, according to the crucible 4 of the present embodiment, the liquid holding member 460 is held so as to be compressed toward the side closer to the bottom wall 422. The same applies to the fifth embodiment of the present embodiment.

As described above, the first side wall region 425a1 of the first side wall portion 425a of the first side wall 425 abuts against the first engaging projection 741 that protrudes from the side wall side protruding portion 724 of the cymbal mounting portion 7. Thereby, even if a force is applied to the -X direction in the mounted state shown in FIG. 3, the positional shift of the crucible 4 in the -X direction can be suppressed. Here, the first side wall portion 425a and the top surface of the first engaging projection 741 are formed to be substantially perpendicular to the bottom wall of the cymbal mounting portion 7 or the bottom wall 422 of the cymbal 4. In other words, the angle formed by the first side wall portion 425a with respect to the bottom wall 422 is substantially perpendicular. Therefore, when an external force is applied to the 匣4 in the -X direction, the first side wall portion 425a of the crucible 4 receives the external force by the first engagement projection 741 in the -X direction, but the first engagement projection is utilized by the cymbal. The 741 generates a force against the external force, so that a vector for applying a force in the -X direction is not generated with respect to the 匣4. Therefore, it is possible to suppress the problem that the crucible 4 floats upward from the bottom wall of the cymbal mounting portion 7. Further, when an external force is applied to the 匣4 in the -X direction, the first side wall portion 425a can be brought into contact with the first side as long as the bottom wall of the mounting portion 7 does not float upward. The engagement protrusion 741 can be used. When the first side wall portion 425a and the first first engagement projection 741 are formed, strictly speaking, there is a variation in the formation of the surface. Therefore, the angle formed by the first side wall portion 425a with respect to the bottom wall 422 is not limited to 90 degrees, as long as it is possible to float the bottom wall of the cymbal 4 from the cymbal mounting portion 7 upward as described above. The scope of the function can be angled. In the present embodiment, the angle of such a range is referred to as substantially vertical.

In the fourth embodiment of the present embodiment, the first side wall portion 425a is set as the third side wall region. 425a3 is located between the first side wall region 425a1 and the second side wall region 425a2, and the thickness of the wall of the third side wall region 425a3 is thinner than the thickness of the walls of the first side wall region 425a1 and the second side wall region 425a2. Thus, according to the crucible 4 of the present embodiment, the first side wall 425 surrounding the liquid holding member 460 is connected to the first side wall region 425a1, the third side wall region 425a3, and the second side wall region 425a2 from the side of the bottom wall 422. The side wall region 425a3 thins the wall thickness, so that the volume of the concave portion 421 accommodating the liquid holding member 460 can be increased. Further, even if the shape of the outer wall side of the first side wall portion 425a is uneven due to the connection of the first side wall portion 425a1, the third side wall portion 425a3, and the second side wall portion 425a2, the inner wall side of the first side wall 425 can be formed. The shape is machined into a uniform, or nearly uniform shape. The same applies to the fifth embodiment of the present embodiment.

As shown in FIG. 13 to FIG. 15, the inner wall surface of the second side wall 426 (see FIG. 10) facing the first side wall 425 is made uniform so that the opening side of the concave portion 421 is widened. The angle is inclined. Thus, according to the crucible 4 of the present embodiment, regardless of the shape of the wall side of the second side wall 426, the liquid holding member 460 can be held so as to be compressed toward the side closer to the bottom wall 422. Moreover, the shape of the inner wall side of the second side wall 426 is uniform regardless of the shape of the outer wall side of the second side wall 426, so that the shape of the molding die can be simplified. The same applies to the fifth embodiment of the present embodiment.

In the crucible 4 of the present embodiment, as shown in FIGS. 13 to 15, the inner wall surface of the second side wall 426 (see FIG. 10) facing the first side wall 425 is inclined and formed into a flat surface. Thus, according to this aspect, the shape of the forming mold can also be simplified.

In the case of the crucible 4 of the present embodiment, as shown in FIG. 16, the supply hole side liquid holding member 406 is positioned between the second side wall portion 425b and the second side wall 426 when viewed from the direction in which the cover 401 faces the bottom wall 422. Thus, the crucible 4 of the present embodiment is such that the supply-hole-side liquid holding member 406 is spaced apart from the first side wall portion 425a of the first side wall 425, and is located in the center or near the center of the liquid holding member 460. As a result, according to the crucible 4 of the present embodiment, the black ink can be made to reach the supply hole side liquid holding member from substantially the entire area of the liquid holding member 460. 406.

The 匣4 of the present embodiment is such that the width of the second side wall portion 425b is wider than the width of the first side wall portion 425a in the first direction from the first end wall 423 toward the second end wall 424. Thus, there are the following advantages. Since the first side wall portion 425a has the first side wall region 425a1 and the second side wall region 425a2, the shape is complicated, and there is little room for performing the treatment for ensuring the strength of the crucible 4. On the other hand, the second side wall portion 425b does not need to have the first side wall portion 425a1 and the second side wall portion 425a2 as in the first side wall portion 425a, and may be inclined with respect to the bottom wall 422. Therefore, the shape is simple. The strength ensures the processing of the room. Thus, according to the crucible 4 of the present embodiment, the width of the second side wall portion 425b corresponding to the simple shape is wider, which is advantageous in terms of strength securing. Specifically, in the fourth embodiment of the present embodiment, the strength is ensured by providing the ribs 428 in the second side wall portion 425b. The same applies to the fifth embodiment of the present embodiment.

In the crucible 4 of the present embodiment, as shown in FIGS. 13 to 14, the angle θ3 formed by the second side wall region 425b2 of the second side wall portion 425b with respect to the bottom wall 422 is larger than the second side wall region of the first side wall portion 425a. The angle θ2 formed by 425a2 with respect to the bottom wall 422. Thus, there are the following advantages. The second sidewall region 425a2 is connected to the first sidewall portion 425a, and is connected to the first sidewall region 425a1 extending from the bottom wall 422 and inclined with respect to the bottom wall 422. The second sidewall region 425b2 and the first sidewall of the second sidewall portion 425b. The portions 425a are positioned side by side in the first direction and are inclined from the bottom wall 422 relative to the bottom wall 422. In this manner, the angle θ3 between the angle θ3 (see FIG. 14 ) formed by the second side wall region 425 b 2 of the second side wall portion 425 b with respect to the bottom wall 422 and the second side wall region 425 a 2 of the first side wall portion 425 a (refer to Similarly to Fig. 13), the peripheral edge portion of the first side wall portion 425a of the lid 401 is shifted from the peripheral edge portion of the second side wall portion 425b. On the other hand, in the fourth embodiment of the present embodiment, the angle θ3 formed by the second side wall region 425b2 with respect to the bottom wall 422 is larger than the angle θ2 formed by the second side wall region 425a2 with respect to the bottom wall 422. The offset between the peripheral edge portion of the first side wall portion 425a and the peripheral edge portion of the second side wall portion 425b in the cover 401 is small. As a result, according to the fourth embodiment of the present embodiment, the cover 401 can be realized. The shape of the second side wall portion 425b is monotonous, and the shape of the lid 401 can be monotonous.

In the fourth embodiment of the present embodiment, the angle θ1 formed by the second side wall portion 425b on the side of the cover 401 with respect to the bottom wall 422 is equal to the angle θ1 formed by the second side wall region 425a2 with respect to the bottom wall 422, and the second The side wall region 425a2 is continuously formed in the first direction described above. Therefore, according to the crucible 4 of the present embodiment, the peripheral edge portion of the second side wall portion 425b of the first side wall 425 on the side of the cover 401 and the peripheral portion of the second side wall portion 425a2 of the first side wall portion 425a are not displaced. Therefore, the shape of the first side 425 on the side of the cover 401 can be monotonous, and the shape of the cover 401 can be monotonous.

In the fourth embodiment of the present embodiment, the first side wall 425 has the first side wall portion 425a, the second side wall portion 425b, and the third side which are arranged in the first direction from the first end wall 423 toward the second end wall 424. Side wall portion 425c. Further, in the first embodiment, the second side wall portion 425b is located between the first side wall portion 425a and the third side wall portion 425c in the first direction, so that the third side wall portion 425c is as shown in FIG. A first sidewall region 425c1 that is substantially perpendicular to the bottom wall 422 is provided on a side of the bottom wall 422. Further, in the fourth embodiment of the present embodiment, as shown in FIG. 25, in the final stage of attaching the crucible 4 to the bracket 8, the first side wall region 425c1 substantially perpendicular to the bottom wall 422 is brought into contact with the electrode assembly 810. The second engagement protrusion 742 is attached to the base. Therefore, according to the crucible 4 of the present embodiment, the first side wall region 425a1 can be brought into contact with the mounting base portion of the electrode assembly 810 in addition to the first side wall region 425a1. The cymbal 4 is positioned more surely on the printer 10, and the mounting posture of the cymbal 4 after installation can be stabilized. The same applies to the fifth embodiment of the present embodiment.

In the fourth embodiment of the present embodiment, the second side wall 426 opposed to the first side wall 425 is also provided with the first side wall portion 426a, the second side wall portion 426b, and the third side wall portion 426c. The side wall portion 426a and the third side wall portion 426c are provided with first side wall regions 426a1 and 426c1 substantially perpendicular to the bottom wall 422 on the side of the bottom wall 422. Further, the first side wall regions 426a1 and 426c1 of the second side wall 426 are placed in a positional relationship with the first side wall regions 425a1 and 425c1 of the first side wall 425 with the bottom wall 422 interposed therebetween, and are in contact with the bracket 8 The first engagement projection 741 and the second engagement projection 742 are formed. Thereby, according to the crucible 4 of the present embodiment, the crucible 4 can be more reliably positioned on the printer 10, and the mounting posture of the crucible 4 after mounting can be further stabilized. The same applies to the fifth embodiment of the present embodiment.
