The bottom wall 422 of the casing 420 is provided with a stepped semicircular protrusion 427 around the liquid supply hole 407, and the semicircular shape is formed in the semicircular shape. The supply hole side liquid holding member 406 (see FIG. 8) is placed on the step portion of the projection 427. 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. 8 or Fig. 9 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. 8, 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. Further, the ink is prevented from moving by the through hole 402a corresponding to the storage position of the liquid holding member 460 and the atmosphere from the atmosphere communication hole 434 of the air groove 403 connected to the through hole 402a.

As described above, the supply hole side liquid having different characteristics is accommodated in the concave portion 421 of the casing 420. The body holding member 406 and the liquid holding member 460 are used in the liquid introduction base 703, and the metal mesh 703s having a larger capillary force than the supply hole side liquid holding member 406 is used, whereby the liquid holding member 460 can be efficiently consumed. Ink. 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, when the micropore density of the liquid holding member 406 and the liquid holding member 460 is equal to each other, the liquid holding members 406 and 460 may be subjected to the water repellency treatment or the hydrophilic treatment to have the capillary force. Size relationship.

The third side wall portion 425c is such that the outer wall surface on the side of the bottom wall 422 is substantially perpendicular to the bottom wall 422. The first side wall portion 426a and the second side wall portion of the second side wall 426 The same is true for the 426b and the third side wall portion 426c. The vertical outer wall surfaces of the first side wall portion 426a and the third side wall portion 426c are separated from the first side wall portion 425a and the third side wall portion 425c of the first side wall 425 via the bottom wall 422. The vertical outer wall surface adopts a so-called back-to-back positional relationship.

The air groove 503, the atmosphere communication hole 534, and the sealing member support seat 537 of each corner are extended. The seal member support base 537 protrudes from the upper surface of the cover 501 at the same height as the peripheral wall of the through holes 502a, 502b, and 502c or the peripheral wall of the air groove 503, and serves as an engagement support for the seal member 504.

The three atmosphere communication holes 534 are located side by side in the X-axis direction at the outer edge of the cover portion 530 and pass through the cover 501. The through holes 502b for the inks of the respective colors of yellow, magenta, and cyan are formed so as to penetrate the cover 501 at the end of the air grooves 503 for the respective colors, and are formed in line with the atmospheric communication holes 534 arranged in the X-axis direction in the Y-axis direction. Further, the atmosphere communication hole 534 and the through hole 502b which are arranged in the Y-axis direction are connected to the back side of the cover 501 by an air groove (not shown). The air groove and the cover back side opening of the through hole 502b and the cover back side opening of the atmosphere communication hole 534 are sealed by the cover back surface sealing member 536. Thereby, the recessed portions 521m, 521c, and 521y of the casing 520 blocked by the cover 501 are opened to the atmosphere through the through hole 502a, the air groove 503, and the through hole 502b through the atmosphere communication hole 534. Further, the through holes 502a, 502b, and 502c and the air groove 503 are sealed on the upper surface side of the cover by the sealing member 504. By the opening of the atmosphere, the porous liquid holding member 560 that accommodates the concave portions 521m, 521c, and 521y of the inks of the respective colors of the casing 520 blocked by the cover 501 receives large Air supply is supplied to the supply hole side liquid holding member 506, the liquid introduction portion 710m of the bracket 8 (see FIG. 4), the liquid introduction portion 710c, or the liquid introduction portion 710y via the ink supply holes 507m, 507c, and 507y. Ink that has been contained. In other words, the ink supply holes 507m, 507c, and 507y in the concave portions 521m, 521c, and 521y also serve as the liquid introduction portion 710m of the ink supply hole 507m to the tray 8, the ink supply hole 507c, and the liquid introduction portion 710c and the ink supply hole 507y. The ink of the respective colors is supplied to the liquid introduction portion 710y. Moreover, the positional relationship of each of the supply holes 507m, 507c, and 507y is as follows.

Between the side walls 526. Further, the ink supply hole 507c is located between the ink supply hole 507m and the second side wall 526.

Further, as shown in FIGS. 17 to 18, the crucible 5 has a first groove 580 and a second groove 581 on the bottom surface (the wall surface on the -Z direction side) of the bottom wall 522 in which the ink supply holes 507m, 507c, and 507y are formed. . The first groove 580 is formed between the ink supply hole 507m corresponding to the magenta liquid introduction portion 710m (see FIG. 4) and the ink supply hole 507c corresponding to the cyan liquid introduction portion 710c, and is supplied from the ink supply hole 507m and the ink. The holes 507c extend toward the ink supply holes 507y. Further, the first groove 580 is formed in a recessed shape at a depth at which the guide protrusion 723 (see FIG. 4) of the cymbal mounting portion 7 is inserted in a state where the cymbal 5 is attached to the cymbal mounting portion 7, and is formed in a concave shape on the partition wall. 572 extends between the extension of the partition wall 572, that is, between the second end wall 524 and the partition wall 571.

The surrounding side wall configuration and the convex rib structure of the casing 5 with respect to the positioning of the cymbal mounting portion 7 assembled to the bracket 8 are substantially the same as those of the cymbal 4.

A-5. Installation posture:

Fig. 19 is an explanatory view schematically showing a first step in the process of attaching the crucibles 4 and 5 to the bracket 8, and Fig. 20 is a view schematically showing the second step in the mounting process of the crucibles 4 and 5. The description of the situation of the step, FIG. 21 is the third step in the installation process of the crucibles 4, 5. The case is partially enlarged and schematically illustrated. FIG. 22 is an enlarged view of the fourth step in the process of mounting the crucibles 4 and 5, and is schematically illustrated. FIG. 23 is a schematic view of the crucible. 4, 5 explanatory diagram of the case of the final step when the bracket 8 is mounted.

In the first step shown in FIG. 19, both the crucibles 4 and the crucibles 5 are inserted into the crucible mounting portion 7 of the bracket 8 in an inclined posture as the outer wall surfaces of the first end walls 423 and 523 face in the -Z direction. In the mounting process with the insertion in the inclined posture, the lower end of the rib of the second convex rib 428b, 528b on the side of the first end walls 423, 523 of the crucibles 4, 5 and the side wall side projection 724 and the first one are The top surface 724t of the protrusion 721 is in contact. In this state, the crucibles 4, 5 are pushed to the side of the end wall portion 730. At this time, the second convex ribs 428b and 528b abut against the top surface 724t and the inclined top surface 724s connected thereto. Thereby, the crucibles 4, 5 are guided to the side of the end wall portion 730 along the trajectory above the two tops.

In the second step shown in Fig. 20, the crucibles 4, 5 are further pressed to the side of the end wall portion 730 in an inclined posture. During the mounting process, the engaging projections 423t, 523t of the first end walls 423, 523 of the cymbals 4, 5 enter the engaging holes 750 in the cymbal mounting portion 7. Thereby, the first end walls 423 and 523 are engaged with the end wall portion 730 of the cymbal mounting portion 7, and thus the posture changes of the cymbals 4 and 5 are restricted during the subsequent mounting. Specifically, the first end walls 423 and 523 of the crucibles 4 and 5 can be restrained from being lifted in the +Z direction.

In the third step shown in FIG. 21, after the engaging projections 423t and 523t are engaged with the engaging holes 750, the lower ends of the ribs of the second convex ribs 428b and 528b of the cymbals 4 and 5 are in contact with the side wall side protruding portions 724. The top surface of the lowest height of the inclined top surface 724s of the first protrusion 721 between the turns, and specifically the top surface of the joint portion of the end wall portion 730. Thereby, the posture change in the -Z direction of the first end walls 423, 523 of the crucibles 4, 5 is restricted. Further, the first convex ribs 428a and 528a of the crucibles 4 and 5 enter the crucible engaging wall surface portion 760. First, the second convex ribs 428a and 528a are in contact with the second wall surface 762 which is inclined with respect to the bottom wall 712 (see FIG. 6) of the cymbal mounting portion 7 constituting the wall surface of the 匣 engaging wall surface portion 760. Next, the first convex ribs 428a and 528a are rubbed against the second wall surface 762, and are moved in the moving direction indicated by the arrow in the enlarged view of Fig. 21 . And, in In the direction equal to the moving direction, the contact portions of the terminals 412 and 512 of the circuit boards 410 and 510 are in close contact with and in contact with the electrode assembly 810. Further, the first side wall portions 425a and 525a of the crucibles 4 and 5 are attached to the first engagement projections 741 which are opposite to the side surface of the engagement hole 750 by the attachment portion 7 having the liquid introduction portion 710b or the like (see the figure). 4. Figure 5).

In the fourth step shown in FIG. 22, in a state where the contact portions of the terminals 412, 512 of the circuit boards 410, 510 are in contact with the electrode assembly 810, the crucibles 4, 5 are pressed in the -Z direction toward the crucible mounting portion 7. Arrived. At this time, the click arm 801 is pushed by the engaging portions 405 and 505 to move in the direction of the arrow (+Y direction) shown in the drawing, and after the 匣4, 5 is attached to the 匣 mounting portion 7, along the -Y The direction moves back to the original position as shown in FIG. 23, and is engaged with the engaging portions 405 and 505. In this process, the third side wall portions 425c and 525c are engaged with the second engagement projections 742 (see FIGS. 4 and 5) opposite to the side faces of the electrode attachment portions 735 of the bracket 8. Further, the first convex ribs 428a and 528a abut against the second wall surface 762 of the crucible engaging wall surface portion 760, and then start to abut against the vertical wall surface surrounding the recess 764. Further, the lower ends of the ribs of the first convex ribs 428a and 528a enter the recess 764. Further, the contact portions of the terminals 412 and 512 of the circuit boards 410 and 510 are rubbed, that is, wiped, with the electrode assembly 810. Further, the wiping is completed by the lower ends of the ribs of the first convex ribs 428a and 528a abutting against the bottom of the recess 764. The change in the position of the crucibles 4, 5 is controlled by the first convex ribs 428a, 528a abutting against the wall surface of the crucible engaging wall surface portion 760.

Further, the moving direction indicated by the arrow in the enlarged view of Fig. 21 is formed by the second wall surface 762 of the 匣-engaging wall surface portion 760 shown in the enlarged view of Fig. 21 with respect to the bottom wall 712 of the cymbal mounting portion 7. Determined by the angle θ1. When the angle θ1 is approximately 90 degrees in total with respect to the angle θ2 formed by the electrode assembly 810 of the bracket 8 with respect to the bottom wall 712 of the cymbal mounting portion 7, the circuit board 410, 510 is formed in the third step. When the contact portions of the terminals 412 and 512 approach and contact the electrode assembly 810, the contact portions of the terminals 412 and 512 are less likely to move by friction with respect to the electrode assembly 810. On the other hand, if the setting is made such that the total of the angle θ1 and the angle θ2 is greater than 90 degrees, in the third step, the contact portions of the terminals 412 and 512 are opposed to the electrode set. The resultant body 810 rubs and moves a large distance.

In the final step shown in FIG. 23, the engaging portions 405, 505 are engaged with the 匣 engaging arm 801. When the crucibles 4 and 5 are pressed toward the crucible mounting portion 7 in the -Z direction, they are lifted in the +Z direction by the reaction force from the liquid introduction portion 710b or the electrode assembly 810. Thereby, the click arm 801 is engaged with the engaging portions 405 and 505. Further, the crucibles 4 and 5 are pressed in the -Y direction by the reaction force from the electrode assembly 810. At this time, the first convex ribs 428a and 528a abut against the vertical wall surrounding the recess 764, and the movement of the crucibles 4, 5 in the -Y direction is restricted. The first convex ribs 428a and 528a are in contact with the vertical wall surface surrounding the recess 764 at the bottom of the recess 764, so that the engaging portions 405 and 505 are engaged with the 匣 engaging arm 801 to maintain the circuit substrate. The contact portions of the terminals 412 and 512 of the 410 and 510 are in contact with the electrode assembly 810. In this manner, the mounting of the crucibles 4, 5 to the crucible mounting portion 7 of the bracket 8 is completed, and the crucibles 4, 5 are in the mounting posture shown in FIG.

When the 匣4, 5 of the present embodiment having the above-described configuration is attached to the cymbal mounting portion 7 of the bracket 8, the first projection is made after the engagement projections 423t and 523t are engaged with the engagement hole 750. The ribs 428a and 528a enter the 匣 engaging wall surface portion 760 (FIG. 21: second step). As a result, in the fourth and fifth embodiments of the present embodiment, the first convex ribs 428a and 528a are in contact with the bottom wall 712 of the wall surface of the crucible engaging wall surface portion 760 with respect to the crucible mounting portion 7 (see FIG. 6). The inclined second wall surface 762 rubs and moves on the second wall surface 762. Thereby, the contact portions of the terminals 412 and 512 of the circuit boards 410 and 510 are brought close to the electrode assembly 810 of the carrier 8, and the contact portion is brought into contact with the electrode assembly 810 (FIG. 22: third step).

With respect to the crucibles 4 and 5 of the present embodiment, the first convex ribs 428a and 528a are further introduced toward the bottom of the recess 764. Thereby, after the contact portions of the terminals 412 and 512 of the circuit boards 410 and 510 are in contact with the electrode assembly 810 of the carrier 8, the contact portion moves while rubbing against the electrode assembly 810. Then, the lower end of the rib of the first convex ribs 428a and 528a abuts against the bottom of the recess 764, thereby limiting the friction of the contact portion, that is, the wiping distance to a specific range. As a result, according to the crucibles 4 and 5 of the present embodiment, the wiping of the mounting process can be improved. The contact portion between the terminals 412 and 512 of the circuit boards 410 and 510 can be electrically connected to the electrode assembly 810 with high reliability.

In the fourth embodiment of the present embodiment, when the first convex ribs 428a and 528a are brought into the bottom of the recess 764, the position of the circuit boards 410 and 510 is changed, and the positions of the circuit boards 410 and 510 are also restricted. The amount of displacement of the change. Therefore, according to the crucibles 4 and 5 of the present embodiment, the wiping range can be prevented from being unexpectedly enlarged.
