However, in the technologies described in Patent Document 1 and Patent Document 2, the unevenness of the size of the container and the holder on which the container is mounted, the deviation of the mounting position when the container is mounted on the holder, the liquid supply port or the liquid introduction are not considered. There are problems such as variations in tube size, changes in the installation environment, and deterioration due to repeated disassembly and assembly. Therefore, even when one or more of these problems occur, a technology that can make the liquid supply port and the liquid introduction tube contact well has been expected.

The dimensional difference in the above-mentioned Y-axis direction is large.

According to this configuration, the dimensional difference between the effective area T and the effective area S of the container in the X-axis direction is larger than the dimensional difference between the effective area T and the effective area S in the Y-axis direction. Therefore, even if the size of the container in the X-axis direction is larger than that of the case in the Y-axis direction, the container has a structure that is more prone to dimensional errors in the X-axis direction than in the Y-axis direction. Even in the middle, the liquid supply port can be brought into good contact with the liquid introduction tube. On the other hand, the container is configured such that the size difference between the effective region T and the effective region S in the Y-axis direction, where dimensional errors are relatively difficult to occur, is smaller than the size difference between the effective region T and the effective region S in the X-axis direction. Thus, by making the size difference between the effective region T and the effective region S relatively small in the Y-axis direction where a dimensional error hardly occurs, the width of the liquid supply port of the container in the Y-axis direction can be suppressed. In addition, the width in the Y-axis direction of the liquid supply port of the printing device can be increased. By suppressing the width of the liquid supply port in the Y-axis direction, for example, the width of the container in the Y-axis direction can be reduced, and the container can be efficiently placed on the rack.

According to this configuration, the dimensional difference between the effective area T and the effective area S of the container in the X-axis direction is larger than the dimensional difference between the effective area T and the effective area S in the Y-axis direction. Therefore, even if the container is accompanied by movement in a direction including the X-axis direction component when it is mounted on the printing device, the container has a feature that errors in the mounting position are more likely to occur in the X direction than in the Y-axis direction when mounted. This structure also enables the liquid supply port to be in good contact with the liquid introduction tube when it is installed in the printing device. In addition, the container is configured such that the size difference between the effective region T and the effective region S in the Y-axis direction, where dimensional errors are relatively difficult to occur, is smaller than the size difference between the effective region T and the effective region S in the X-axis direction. Thus, by making the size difference between the effective region T and the effective region S relatively small in the Y-axis direction where a dimensional error hardly occurs, the width of the liquid supply port of the container in the Y-axis direction can be suppressed. In addition, the width of the liquid supply port of the printing device in the Y-axis direction can be increased. Thereby, for example, the width of the container in the Y-axis direction can be reduced, and the container can be efficiently arranged on the rack.

The ink supplied to the ink channel 553 through the device-side filter 554 passes through a region of the device-side filter 554 inside the annular welded portion 558 . This area is referred to as "effective area S". That is, the so-called effective area S refers to an area that effectively functions for the flow of ink in the device-side filter 554 . In the XY plane including the opening end 552 of the cylindrical portion 551 , the effective area S is equal to the area surrounded by the opening end 552 . In addition, in the XY cross-section of the cylindrical portion 551 , the effective area S is equal to the area surrounded by the inner peripheral surface 559 . That is, the effective area S is equal to the XY cross section of the ink flow path 553 . Therefore, the so-called effective region S can also be said to be a region that effectively functions for the flow of ink in the liquid introduction tube 550 . In addition, the so-called effective area S can also be said to be an area where ink can be introduced in the liquid introduction tube 550 . The effective dimension A of the effective region S in the X-axis direction is preferably larger than the effective dimension B of the effective region S in the Y-axis direction. With such a structure, it is possible to efficiently receive ink supply from the liquid supply ports 480 of a plurality of containers arranged in parallel in the Y-axis direction. The effective area S according to the present embodiment has an elliptical shape extending in the X-axis direction. Since the welded portion 558 is annularly formed on the upper surface of the device-side filter 554 , the size and area AS of the effective region S can be determined by measuring the inner side of the welded portion 558 through calculation. The area AS of the active region S is preferably set to 35.25 mm 2 . In addition, the effective dimension A of the effective region S in the X-axis direction is preferably set to 8.8 mm. In addition, the effective size B of the effective area S in the Y-axis direction is preferably set to 4.5 mm. By setting such a size, it is possible to suppress the occurrence of the following situations: the effective dimension A of the effective region S in the X-axis direction is larger than the necessary value with respect to the structure of the liquid supply port 480 of the container, and the Y dimension of the effective region S When the effective dimension B in the axial direction becomes smaller and the flow path resistance increases. The above-mentioned area and size are just one example, and the effective region S may have an area and size other than those described above.

The second front surface 407 and the slope 408 are formed at the corner between the front surface 403 and the bottom surface 401 . Each of the surfaces 401 to 408 is substantially flat. The term "approximately flat" refers to a case where the entire area of the surface is completely flat and a case where a part of the surface has unevenness. That is, the case where the surface and the wall of the box body 42 constituting the container 40 can be determined although some unevenness is present on a part of the surface is included. The outer shapes of the respective surfaces 401 to 408 are substantially rectangular. In this embodiment, each of the surfaces 401 to 408 may constitute an outer surface of an assembled body in which a plurality of components are assembled. In this embodiment, each of the surfaces 401 to 408 is formed of a plate-shaped member. In other embodiments, a part of each of the surfaces 401 to 408 may be formed of a film-shaped (film-shaped) member.

As shown in FIGS. 10 and 16 , inside the cylindrical portion 488 , a tank-side filter 473 for allowing the ink flowing through the liquid supply port 480 to flow out from the liquid storage chamber 400 to the outside is arranged. The container-side filter 473 is in contact with the device-side filter 554 provided at the tip of the cylindrical portion 551 (see FIG. 5 ) in the mounted state. As a result, the ink flows toward the cylindrical portion 551 through the tank-side filter 473 . The tank-side filter 473 is formed of a porous sheet member through which ink can flow.

As shown in FIGS. 10 and 16 , in the liquid supply port 480 , a communication port 483 serving as an opening for communicating the inside of the liquid supply port 480 with the outside is formed. When the container 40 is vertically projected on the bottom surface 401 , the communicating port 483 is provided at a position not overlapping the container-side filter 473 . Through the communication port 483 , the region where the air exists in the liquid supply port 480 (internal space) is communicated with the outside (external atmosphere), so that the pressure difference between the internal space and the outside can be kept substantially constant.

As shown in FIGS. 10 and 16 , a prism unit 460 is arranged on the bottom surface 401 . The prism unit 460 includes a so-called rectangular prism 465 . The rectangular prism 465 has two surfaces (not shown) that intersect approximately at right angles. These two surfaces are located within the liquid containment chamber 400 . The prism unit 460 is used when the control unit of the printer 20 judges the presence or absence of ink inside the container 40 . When the light emitting unit (not shown) disposed below the bracket 50 emits light toward the rectangular prism 465 , the control unit of the printer 20 determines the presence of ink according to whether the light receiving unit (not shown) receives reflected light.

As shown in FIGS. 10 and 16 , a protruding first container-side locking portion 410 is formed on the front surface 403 . The first container-side locking portion 410 has a shape in which the tip protrudes in the +X-axis direction. The first container-side locking portion 410 is locked to the operation lever 512 in the attached state. As shown in FIGS. 9 and 13 , on the rear surface 404 , a protruding second container-side locking portion 421 is formed. The second container-side locking portion 421 has a shape in which the tip protrudes toward the −X axis direction. In the mounted state, the second container-side locking portion 421 is inserted and locked into the second device-side locking portion 513 that is a recess formed in the rear wall portion 503 (see FIG. 4 ). That is, the container 40 in the mounted state is locked on both sides in the X-axis direction by the first device-side locking portion 512 c and the second device-side locking portion 513 included in the holder 51 , and is positioned relative to the holder 51 .

As shown in FIG. 10 , the circuit board 45 is provided on the slope 408 . On the surface of the circuit board 45 , a terminal group 450 that contacts the contact mechanism 525 (see FIG. 6 ) of the bracket 51 in the mounted state is formed. In addition, a storage device for storing various information (ink presence, ink color, etc.) of the container 40 is provided on the back surface of the circuit board 45 . As shown in FIG. 9 , an air vent 490 for introducing air into the container 40 is formed on the left side 405 .

As shown in FIGS. 11 to 16 , it is preferable to make the dimension E along the X-axis direction of the container 40 larger than the dimension W along the Y-axis direction (E>W). Here, the dimension E of the container 40 in the X-axis direction refers to the distance from the tip of the first container-side locking portion 410 protruding in the +X-axis direction to the second container-side locking portion 421 protruding in the −X-axis direction. The length of the tip along the X-axis. The so-called dimension W of the container 40 along the Y-axis direction refers to the length along the Y-axis direction from the left side 405 to the right side 406 , which is the same as the dimension of the box body 42 along the Y-axis direction. In addition, it is more preferable for the container 40 that the dimension D along the X-axis direction of the box body 42 is larger than the dimension W along the Y-axis direction (D>W). Here, the so-called dimension D of the box body 42 along the X-axis direction refers to the length along the X-axis direction from the front 403 to the back 404 . This is because, since the size of the container accommodating chamber 506 of the support 51 is limited in the Y-axis direction, in the case of a structure in which a plurality of containers 40 are installed side by side along the Y-axis direction on the support 51, it is necessary to make the edges of the containers 40 The width in the Y-axis direction shrinks. The dimension E of the container 40 in the X-axis direction is preferably 90 mm. Furthermore, the dimension D of the case body 42 in the X direction is preferably 84 mm. Furthermore, the dimension W of the container 40 in the Y-axis direction is preferably 12.7 mm. By adopting such dimensions, the width in the Y-axis direction can be suppressed while ensuring the capacity of the liquid storage chamber 400 inside the case 42 . The above-mentioned dimensions are just one example, and the container 40 may have dimensions other than the above-mentioned ones.

The dimension J of the container 40 in the Z-axis direction is preferably 32.5 mm. Here, the dimension J along the Z-axis direction of the container 40 refers to the length along the Z-axis direction from the top surface 402 to the opening end 489 of the cylindrical portion 488 . In addition, the dimension H of the case body 42 in the Z-axis direction is preferably 28 mm. The so-called dimension H of the box body 42 along the Z-axis direction refers to the length along the Z-axis direction from the top surface 402 to the bottom surface 201 . By setting such dimensions, it is possible to suppress the weakening of the movement of the carriage 50 due to the increase in the capacity of the liquid storage chamber 400 while ensuring the capacity of the liquid storage chamber 400 . The composition of the container 40 is: the size E, the size D, the size W, the size J, and the size H are in descending order E>D>J>H>W. In addition to the size relationship between size E and size D (E>D), and size J and size H (J>H), the size relationship between size E, size D, size J, size H, and size W can be It can be changed arbitrarily, for example, the dimensions of the container 40 can also be J>H>E>D>W in descending order, or J>E>D>H=W.

Fig. 17 is an explanatory diagram illustrating a ZX section of a container. Inside the container 40 , in addition to the liquid storage chamber 400 , a partition plate 430 for partitioning the liquid storage chamber 400 into two and a communication port 481 for communicating the liquid storage chamber 400 with the liquid supply port 480 are provided. The partition plate 430 partitions the liquid storage chamber 400 into an upper space 400a and a lower space 400b. The partition plate 430 is connected to the left side 405 , right side 406 , back 404 , and bottom 401 of the box body 42 such that the side in the +X-axis direction is lower than the side in the -X-axis direction (-Z-axis direction). tilt. Furthermore, the end portion of the partition plate 430 on the +X-axis direction side has an opening (not shown) that communicates the upper space 400 a and the lower space 400 b. The communication port 481 is provided on the bottom surface of the lower space 400 b for supplying the liquid in the lower space 400 b to the liquid supply port 480 . The communication port 481 may be one opening or may be composed of a plurality of openings. The container 40 according to this embodiment is configured such that when air (bubbles) flows in from the liquid supply port 480 through the communication port 481 , the bubbles move in the −X-axis direction along the lower surface of the partition plate 430 , so they do not move. into the upper space 400a, but stored in the lower space 400b. In addition, the partition plate 430 may also be omitted.

The detailed structure of the liquid supply port will be described with reference to FIGS. 18 to 20 . Fig. 18 is an exploded perspective view of a liquid supply port. Fig. 19 is an explanatory diagram illustrating a ZX cross section of a liquid supply port. Fig. 20 is an explanatory diagram when viewing the liquid supply port from the Z-axis direction. The liquid supply port 480 has a structure in which a leaf spring 471, a foam member 472 as a flow path forming member, and a container as a container-side porous member are arranged in a recess 470 provided on the bottom surface 401 of the case body 42. Side filter 473. A communication port 481 is arranged in a portion of the case body 42 between the recess 470 and the liquid storage chamber 400 .

The container side filter 473 is a porous member provided on the outermost surface of the liquid supply port 480 . The peripheral portion 473 a of the container-side filter 473 is welded to the outer peripheral portion 485 of the concave portion 470 of the case 42 . The central portion 473 b of the container-side filter 473 is formed in a planar shape, and protrudes outward (to the −Z-axis direction side) from the peripheral portion 473 a of the container-side filter 473 . The central portion 473b of the container side filter 473 is a rectangular flat surface extending in the X-axis direction. When the container 40 is mounted on the holder 51 , the central portion 473 b is in contact with the device-side filter 554 provided on the holder 51 . The inclined portion 473c between the peripheral portion 473a and the central portion 473b of the container side filter 473 forms a meniscus of ink without contacting the device side filter 554 when the container 40 is mounted on the holder 51 . This meniscus prevents liquid from leaking from the inclined portion 473c of the container-side filter 473 in a state where the container 40 is attached to the holder 51 . In addition, the central portion 473b of the container-side filter 473 contacts the foam member 472 , while the inclined portion 473c does not contact the foam member 472 .

As the container side filter 473, it is preferable to use a filter that can be welded to the case body 42, has a small pressure loss, and has a high meniscus pressure resistance. As such a filter material, for example, a filter having through holes formed in the membrane by press working or the like, an asymmetric membrane such as MMM membrane manufactured by PALL, or a symmetric membrane such as woven cloth can be used. In addition, "meniscus pressure resistance" refers to a pressure that can withstand the meniscus of ink (liquid) without being broken, and is also called "bubble point pressure".

In addition, regarding the forming method of the container side filter 473, before welding the filter material to the outer peripheral portion 485 of the case body 42, the filter material may be processed and shaped in advance so that the peripheral portion 473a, central portion 473b, Inclined portion 473c. In addition, when the filter material is welded to the outer peripheral portion 485 of the case 42, the filter material may be deformed so that the peripheral portion 473a, the central portion 473b, and the inclined portion 473c can be distinguished.

As described above, the ink supplied to the liquid introduction tube 550 through the container-side filter 473 passes through the central portion 473b of the container-side filter 473 as a region surrounded by the inclined portion 473c. Thus, the central portion 473b of the tank-side filter 473 is a region that effectively functions in terms of the flow of ink in the liquid supply port 480 . This area is referred to as "effective area T". That is, the so-called effective region T refers to a region in which ink can be efficiently supplied in the liquid supply port 480 . In addition, the so-called effective area T refers to an area in the liquid supply port 480 that can be in contact with the liquid introduction tube 550 . In addition, the effective region T refers to a region where ink can be supplied to the liquid introduction tube 550 when the liquid supply port 480 is in contact with the liquid introduction tube 550 . In addition, the so-called effective area T refers to an area including a contact surface with the liquid introduction tube 550 when the liquid supply port 480 comes into contact with the liquid introduction tube 550 . In addition, the so-called effective region T refers to a region in the liquid supply port 480 that is on the same plane as the contact surface with the liquid introduction pipe 550 when it comes into contact with the liquid introduction pipe 550 .

The ink supplied from the tank 40 to the print head 52 requires a certain flow rate. In order to increase the ink flow rate per unit time, it is preferable to expand the effective area T. FIG. On the other hand, since the size of the container storage chamber 506 of the holder 51 is limited, it is necessary to reduce the width of the container 40 in the Y-axis direction. Therefore, it is preferable to reduce the width in the Y-axis direction of the liquid supply port 480 located on the bottom surface 401 of the case 42 of the container 40 . Therefore, as shown in FIG. 20 , it is preferable to make the effective size L of the effective region T along the X-axis direction larger than the effective size M along the Y-axis direction (L>M). In addition, the effective area T preferably has a rectangular shape extending in the X-axis direction. Since the central portion 473b of the container-side filter 473 is exposed to the outside of the container 40, the size and area AT of the effective region T can be determined by measuring the central portion 473b through calculation. The area AT of the effective region T is preferably larger than 35.2 mm ² and not more than 176.25 mm ² . The area AT of the effective region T is more preferably 131.76 mm ² . In addition, the effective dimension L of the effective region T in the X-axis direction is preferably 13.7 mm. In addition, the effective size M of the effective area T along the Y-axis direction is preferably 5.25 mm. By setting such a size, it is possible to suppress the occurrence of the following: the effective dimension L of the effective region T along the X-axis direction is larger than the necessary value with respect to the liquid introduction tube 550 of the holder 51, and the occurrence of the situation that the effective dimension L of the effective region T along the Y axis is larger than necessary. When the effective dimension M in the axial direction becomes smaller, the flow path resistance between the liquid introduction tubes 550 increases. The above-mentioned area and size are just one example, and the effective region T may have an area and size other than those described above.

As shown in FIGS. 18 and 19 , the leaf spring 471 has an integral structure including a biasing member 474 and a supporting member 475 . The leaf spring 471 has a height substantially equal to or slightly higher than the depth of the recess 470 provided in the case body 42 . The plate spring 471 is arranged in the recessed portion 470 so that the side of the support member 475 faces the container-side filter 473 (the side in the −Z-axis direction). The urging member 474 is formed by bending legs provided at both ends of the long plate-shaped supporting member 475 so as to cross in the +Z-axis direction. A plurality of circulation holes 476 penetrating in the Z-axis direction are provided in the flat support member 475 . The urging member 474 has a function of indirectly pressing the container-side filter 473 to the device-side filter 554 through the foam member 472 while making contact with the container 40 when the container 40 is attached to the holder 51 . During this pushing process, the support member 475 indirectly supports the container-side filter 473 in a planar form via the foam member 472 so that the container-side filter 473 is in surface contact with the device-side filter 554 . The urging member 474 is preferably designed such that the surface area on the X, Y plane is equal to the area AT of the effective area T. As shown in FIG. In addition, in the present embodiment, the urging member 474 and the support member 475 are integrally formed as the leaf spring 471, but they may be configured as different members. In this case, the urging member 474 is not limited to the leaf spring 471 as long as it has a function of urging the container side filter 473 to the outside, and may be formed of other elastic bodies such as coil springs or elastic rubber.

The foam member 472 is a porous member disposed between the leaf spring 471 and the container-side filter 473 . The foam member 472 supplies the container-side filter 473 in a planar spread of the liquid supplied from the liquid storage chamber 400 through the flow hole 476 provided in the supporting member 475 of the leaf spring 471 . The thickness of the foam member 472 is set to a thickness capable of spreading the liquid supplied from the circulation hole 476 in a planar manner. The rigidity of the foam member 472 is such that the flow path in the foam member 472 is not closed when the container side filter 473 is biased toward the device side filter 554 by the plate spring 471 . Protruding portions 477 bent toward the leaf spring 471 are respectively provided on the +X-axis direction side end and the −X-axis direction side end of the foam member 472 . The protruding portion 477 is fitted into the recessed portion 478 provided at the end portion on the +X-axis direction side and the end portion on the −X-axis direction side of the plate spring 471 , respectively. Thereby, the foam member 472 is positioned relative to the leaf spring 471 .

FIG. 21 is an explanatory diagram illustrating an XZ cross section in a state where a container is attached to a holder. By locking the first container-side locking portion 410 of the container 40 to the first device-side locking portion 512c of the holder 51, the second container-side locking portion 421 of the container 40 is locked to the second device-side locking portion 513 of the holder 51. , so that the container 40 is mounted on the bracket 51. That is, the container 40 is attached to the holder 51 with its end in the +X-axis direction in contact with the lock contact mechanism 520 and its end in the −X-axis direction in contact with the chamber rear mechanism 540 . In other words, the container 40 is attached to the holder 51 in a state where both end portions along the X-axis direction are in contact with mutually different members constituting the holder 51 . When the container 40 is attached to the holder 51 , the liquid supply port 480 of the container 40 is connected to the liquid introduction pipe 550 of the holder 51 . Thus, the ink stored in the liquid storage chamber 400 of the container 40 is supplied to the ink discharge unit 573 through the liquid supply port 480 of the container 40 and the liquid introduction tube 550 of the holder 51 . Specifically, the ink stored in the liquid storage chamber 400 sequentially passes through the communication port 481, the plate spring 471, the foam member 472, the container side filter 473, the device side filter 554, the cylindrical portion 551, the flow path forming plate 542, The second board 544 , the electrical wiring board 571 , and the first board 572 are supplied to the ink discharge unit 573 . The container 40 is arranged so as to straddle the boundary portion between the holder base member 510 and the storage chamber rear mechanism portion 540 in the X-axis direction. That is, the +X-axis direction side of the container 40 is arranged above the holder base member 510 , and the −X-axis direction side is arranged above the storage chamber rear mechanism part 540 .

Referring to FIGS. 22 and 23 , the positional relationship between the liquid supply port 480 and the liquid introduction pipe 550 when the container 40 is mounted on the holder 51 will be described. Fig. 22 is an explanatory diagram illustrating a ZX cross section when the liquid supply port is in contact with the liquid introduction pipe. FIG. 23 is an explanatory diagram illustrating the positional relationship between the effective area T and the effective area S in the Z-axis direction when the liquid supply port is in contact with the liquid introduction pipe. The effective area T of the liquid supply port 480 of the container 40 refers to an area where ink can be supplied to the liquid introduction tube 550 of the holder 51 when in contact with the liquid introduction tube 550 . On the other hand, the so-called effective area S of the liquid introduction tube 550 of the holder 51 refers to an area where ink effectively flows through the liquid introduction tube 550 . Therefore, it is preferable that when the container 40 is mounted on the bracket 51 and the container side filter 473 is in close contact with the device side filter 554 as shown in FIG. 22, as shown in FIG. The inner side of the area T includes the effective area S of the liquid introduction tube 550 .

Therefore, the container 40 is configured such that the area AT of the effective area T of the liquid supply port 480 is larger than the area AS of the effective area S of the liquid introduction pipe 550 (AT>AS). In addition, the container 40 is configured such that the effective size L of the effective area T in the X-axis direction is larger than the effective size A of the effective area S in the X-axis direction (L>A), and that the effective size M of the effective area T in the Y-axis direction It is larger than the effective dimension B of the effective area S in the Y-axis direction (M>B). That is, the container 40 is configured such that the dimensional difference P between the effective regions T and S in the X-axis direction is larger than the dimensional difference R between the effective regions T and S in the Y-axis direction (P>R). Here, the size difference P refers to the difference between the effective size L of the effective region T in the X-axis direction and the effective size A of the effective region S in the X-axis direction (P=L−A). In addition, the so-called size difference R refers to the difference between the effective size M of the effective region T in the Y-axis direction and the effective size B of the effective region S in the Y-axis direction (R=MB).

With such a configuration, when the container 40 is mounted on the holder 51 and includes the effective area S inside the effective area T, the clearance Q in the X-axis direction between the effective area T and the effective area S can be made larger than that in the Y-axis direction. The clearance S is large (Q>S). The so-called clearance Q in the X-axis direction refers to the sum of gaps in the effective region T formed on both sides of the effective region S in the X-axis direction (Q=Q1+Q2). In addition, the so-called clearance S in the Y-axis direction refers to the sum of gaps between the effective regions T formed on both sides of the effective region S in the Y-axis direction (S=S1+S2).

In this way, by making the clearance Q in the X-axis direction larger than the clearance S in the Y-axis direction, even if the container 40 has a structure in which dimensional errors are more likely to occur in the X-axis direction than in the Y-axis direction, it is possible to keep the liquid The supply port 480 is in good contact with the liquid introduction tube 550 . The container 40 in which dimensional errors are more likely to occur in the X-axis direction than in the Y-axis direction refers to: for example, the container 40 in this embodiment has a case 42 with a dimension D in the X-axis direction that is larger than that in the Y-axis direction. A container 40 or the like having a large dimension W in the direction. On the other hand, by making the clearance S in the Y-axis direction smaller than the clearance Q in the X-axis direction, the dimension W of the liquid supply port 480 of the container 40 in the Y-axis direction can be suppressed. In addition, the width B in the Y-axis direction of the liquid introduction tube 550 of the holder 51 can be increased. By suppressing the dimension W of the liquid supply port 480 in the Y-axis direction, for example, the width of the container 40 in the Y-axis direction can be reduced, and the container can be efficiently placed on the rack. Furthermore, by widening the dimension B in the Y-axis direction of the liquid introduction tube 550 , it is possible to increase the flow rate of the liquid flowing between the liquid supply port 480 and the liquid introduction tube 550 .

In addition, the container 40 is configured such that the ratio Q/S of the clearance Q in the X-axis direction to the clearance S in the Y-axis direction and the ratio D/S of the dimension D of the case 42 in the X-axis direction to the dimension W in the Y-axis direction W is roughly equal. Here, "approximately equal" means that the difference between the two is about ±5%. More preferably, the difference between the two is about ±2%. For example, if the effective dimension A of the effective area S of the liquid introduction pipe 550 of the support 51 is 8.8 mm in the X-axis direction, and the effective dimension B in the Y-axis direction is 4.5 mm, the box body 42 of the container 40 is 4.5 mm in the X-axis direction. The upper dimension D is 84mm, and the dimension W in the Y-axis direction is 12.7mm, then it is preferable to set the effective dimension L in the X-axis direction of the effective area of the liquid supply port 480 as 13.7mm, and set the effective dimension L in the Y-axis direction to 13.7mm. The dimension M is set to 5.25 mm. If so, the clearance Q in the X-axis direction is 4.9mm (=13.7-8.8), and the clearance S in the Y-axis direction is 0.75mm (=5.25-4.5), so the gap between the clearance Q and the clearance S The ratio Q/S was 6.67 (4.9/0.75). Since the ratio D/W of the dimension D in the X-axis direction of the case 42 to the dimension W in the Y-axis direction is 6.61 (84/12.7), the ratio Q/S is approximately equal to the ratio D/W.

By making the ratio Q/S of the clearance Q in the X-axis direction to the clearance S in the Y-axis direction and the ratio D/W of the dimension D in the X-axis direction of the case 42 to the dimension W in the Y-axis direction approximately On the other hand, it is possible to suppress, for example, that the effective region T becomes larger than a necessary value in the X-axis direction. The dimensional error is proportional to the length of the case 42 . Therefore, the ratio D/W of the dimension D in the X-axis direction of the box body 42 to the dimension W in the Y-axis direction is similar to the ratio of the dimensional error in the X-axis direction of the box body 42 to the dimensional error in the Y-axis direction. By making the ratio Q/S of the clearance Q in the X-axis direction to the clearance S in the Y-axis direction approximately equal to the ratio of the dimensional error in the X-axis direction of the case 42 to the dimensional error in the Y-axis direction, it is possible to efficiently The effective area S is arranged inside the effective area T. As shown in FIG.

The operation (attachment operation) at the time of attaching the container to the rack will be described with reference to FIGS. 24 to 26 . In FIGS. 24 to 26 , the container 40 and the holder 51 are shown in a manner corresponding to FIGS. 6 and 17 . In FIGS. 24 to 26 , the state of attaching the container 40 to the holder 51 is shown in time series in the order of FIGS. 24 to 26 .

When attaching the container 40 to the holder 51, the container 40 is inserted from above the holder 51 as shown in FIG. 24 . And, while moving the container 40 from the second container-side locking portion 421 side to the inside of the holder 51 along the direction (the lower right direction in FIG. 2. The container-side locking portion 421 is inserted into the second device-side locking portion 513. In the state shown in FIG. 24 , the first container-side lock portion 410 of the container 40 is located on the +Z-axis direction side of the first device-side lock portion 512 c on the operating lever 512 .

Next, from the state shown in FIG. 24 , the container 40 is rotated counterclockwise when viewed from the -Y axis direction with the second container-side locking portion 421 inserted into the second device-side locking portion 513 as a fulcrum of rotation, that is, , rotate to push the front face 403 side toward the bottom wall portion 501 of the bracket 51 . Then, as shown in FIG. 25, while the first container-side locking portion 410 is restricted from moving in the Y-axis direction and the X-axis direction by the guide portion 516 of the operating lever 512, that is, the guide wall portion 517 and the guide bottom wall surface 518, One side advances in a direction (lower right direction in FIG. 25 ) including components in the −Z-axis direction and the −X-axis direction.

Furthermore, when the container 40 is rotated from the state shown in FIG. 25 and the front surface 403 side is pushed in, the 1st container side lock part 410 is further pushed in - Z axis direction side. Then, as shown in FIG. 26 , the operation lever 512 is pushed in the −X-axis direction by the first container-side locking portion 410 and rotates clockwise when viewed from the −Y-axis direction. At this time, the operating lever 512 abuts against the spring 528 and receives an urging force from the spring 528 along the direction of pushing the operating lever 512 counterclockwise when viewed from the -Y axis direction. direction. This acting force is an external force including a component in the -X axis direction. That is, the rotational area of the operating lever 512 is limited by the spring 528 . The operating lever 512 abuts against the spring 528 and is biased from the state shown in FIG. 26 , until the container 40 is further pushed in, and the first container-side locking portion 410 passes over the guide portion 516 of the operating lever 512. .

And then, rotate from the state shown in Figure 26, to push in the front 403 side of the container 40, if the first container side locking part 410 gets over the guide part 516 of the operating lever 512, the operating lever 512 rotates to make the first container The side lock portion 410 moves to the −X axis direction, and as shown in FIG. 21 , the first device side lock portion 512c moves in the −X axis direction to lock the first container side lock portion 410 . Accordingly, the movement of the container 40 in the +Z axis direction is restricted. In addition, by connecting the liquid supply port 480 of the container 40 to the liquid introduction tube 550, the second container-side locking portion 421 engages with the second device-side locking portion 513, and the first container-side locking portion 410 engages with the first device-side locking portion 512c. cooperation, thereby completing the installation of the container 40 to the bracket 51 . Furthermore, by correctly mounting the container at the designed installation position, the terminal group 450 of the circuit board 45 on the container side is electrically connected to the device-side terminal 527, thereby enabling signal transmission between the container 40 and the printer 20. As described above, when the container 40 is attached to the holder 51 , it is attached to the holder 51 while being moved in a direction including the −X axis direction component. Therefore, at the time of mounting, an error in the mounting position is more likely to occur in the X-axis direction than in the Y-axis direction. Due to the structure of the container 40, the size difference P between the effective area T and the effective area S in the X-axis direction is larger than the size difference R between the effective area T and the effective area S in the Y-axis direction (P>R), so even when the The liquid supply port 480 can be satisfactorily connected to the liquid introduction pipe 550 even if there is a positional error.

According to the container 40 of the first embodiment described above, when the container 40 is attached to the holder 51 and includes the effective region S inside the effective region T, the clearance in the X-axis direction between the effective region T and the effective region S can be reduced. Q is larger than the clearance S in the Y-axis direction (Q>S). Accordingly, even if the container 40 has a structure in which dimensional errors are more likely to occur in the X-axis direction than in the Y-axis direction, the liquid supply port 480 can be brought into good close contact with the liquid introduction tube 550 . As a result, the liquid contained in the container 40 can be stably supplied to the printer 20 . A container 40 that is more prone to dimensional errors in the X-axis direction than in the Y-axis direction refers to a container 40 other than the container 40 of this embodiment, which has a case 42 whose dimension D in the X-axis direction is larger than that in the Y-axis direction. In addition to the container 40 having a large dimension W, a container having a structure having a different expansion rate in the X-axis direction and a Y-axis direction, a container configured by combining a plurality of components in the X-axis direction, etc. wait.

In addition, even if the container 40 has a structure in which an error in the mounting position is more likely to occur in the X-axis direction than in the Y-axis direction when the container 40 is mounted on the holder 51, the liquid supply port 480 can be brought into good close contact with the liquid introduction port. Tube 550 on. The container 40 that is more likely to cause errors in the mounting position in the X-axis direction than in the Y-axis direction at the time of mounting refers to a container 40 other than the container 40 of this embodiment, which is accompanied by the direction of the X-axis when it is mounted on the printer 20. In addition to the container 40 that moves in the direction of the axis direction component, it is also possible to exemplify a container that locks both sides along the X-axis direction when mounted on the bracket, and when mounted on the bracket, the container is locked by the operating lever provided on the bracket. A container that pushes in the direction of the X axis, etc. Also, when the holder 51 is composed of a plurality of parts and the plurality of parts come into contact with the container 40 at different positions along the X-axis direction as in the present embodiment, an error in the mounting position along the X-direction is likely to occur.

In addition, according to the container 40 of the first embodiment, when the container 40 is mounted on the bracket 51, the container side filter 473 applies a force to the device side filter 554 side through the biasing member 474, so the container side filter 473 can be absorbed. The deviation of the pressing force for the device-side filter 554 . As a result, even if there are individual differences in the container 40 (liquid supply port 480 ) or the printer 20 (liquid introduction tube 550 ), environmental changes, plastic deformation due to repeated attachment and detachment, etc., the container side filter 473 can be connected to the device side. The contact state of the filter 554 becomes good. As a result, the ink in the container 40 can be stably supplied to the printer 20 . In addition, in the present embodiment, the leaf spring 471 is provided with a flat support member 475 , and the container side filter 473 is biased by the biasing member 474 via the support member 475 . Therefore, the container-side filter 473 can be uniformly brought into contact with the device-side filter 554 .

B. Second Embodiment:

Fig. 27 and Fig. 28 are explanatory diagrams illustrating examples of containers according to the second embodiment. Fig. 27 is an external perspective view of a container according to the second embodiment. Fig. 28 is a bottom view of the container according to the second embodiment. Regarding the container 40 a shown in FIGS. 27 and 28 , the parts corresponding to the respective parts of the container 40 according to the first embodiment are assigned the same reference numerals as those of the container 40 . The dimension _W2 in the Y-axis direction of the container 40a shown in FIGS. 27 and 28 is approximately twice the dimension W in the Y-axis direction of the container 40 in the first embodiment. The dimensions of other parts (dimension E, dimension D, dimension H, and dimension J) are the same as those of the first embodiment. Two liquid supply ports 480 are provided along the width direction (Y-axis direction) on the bottom surface 401 of the container 40 a. In addition, two second container-side locking portions 421 are provided along the Y-axis direction on the back surface 404 of the container 40a. The container 40a is mounted across two slots in the bracket 51 . Except for the above points, the container 40 a shown in FIGS. 27 and 28 , including the container in the modified example, is the same as the container 40 ( FIG. 10 ) of the first embodiment. Thereby, the same effect as that of the first embodiment can be obtained. In addition, three or more liquid supply ports 480 may be provided along the width direction (Y-axis direction). The container 40a of the second embodiment is a container having two effective regions T of the container 40 described in the first embodiment, and the total of the effective regions formed by the two liquid supply ports 480 does not correspond to that of the first embodiment. Effective area T.

The dimension E of the container 40a in the X-axis direction can be set to 90 mm. In addition, the dimension D of the X direction of the box body 42 may be set to 84 mm. In addition, the dimension _W2 of the Y-axis direction of the container 40a can be made into 24.7 mm. The dimension J of the Z-axis direction of the container 40a can be set to 32.5 mm. The dimension H of the box body 42 in the Z-axis direction can be set to 28 mm. By setting such dimensions, it is possible to suppress the weakening of the movement of the carriage 50 due to the increase in the capacity of the liquid storage chamber 400 while ensuring the capacity of the liquid storage chamber 400 . The above-mentioned dimensions are just one example, and the container 40a may be set to a size other than the above-mentioned ones.

The structure of the container 40a is such that the ratio Q/S of the clearance Q in the X-axis direction to the clearance S in the Y-axis direction and the half of the dimension D in the X-axis direction of the box body 42 and the dimension W in the Y _- axis direction (W ₂ /2) is approximately equal to the ratio D/(W ₂ /2). Here, "approximately equal" means that the difference between the two is about ±5%. More preferably, the difference between the two is about ±2%. For example, if the effective dimension A of the effective area S of the liquid introduction pipe 550 of the support 51 is 8.8mm in the X-axis direction, and the effective dimension B in the Y-axis direction is 4.5mm, the X-axis direction of the box body 42 of the container 40a The dimension D of is 84mm, the dimension W ₂ of the Y-axis direction is 24.7mm, then preferably the effective dimension L of the X-axis direction of the effective region of the liquid supply port 480 is set to 13.7mm, and the effective dimension M of the Y-axis direction is Set to 5.25mm. If so, the clearance Q in the X-axis direction is 4.9mm (=13.7-8.8), and the clearance S in the Y-axis direction is 0.75mm (=5.25-4.5), so the ratio of the clearance Q to the clearance S is Q/ S was 6.67 (4.9/0.75). Since the ratio D/(W ₂ /2) of the dimension D in the X-axis direction of the box body 42 to the half (W ₂ /2) of the dimension W ₂ in the Y-axis direction is 6.80 (84/(24.7/2)), so The ratio Q/S and the ratio D/W are approximately equal. By setting the ratio Q/S of the clearance Q in the X-axis direction to the clearance S in the Y-axis direction as described above and the half of the dimension D in the X-axis direction of the box body 42 and the dimension W _in the Y-axis direction (W ₂ The ratio D/(W ₂ /2) of /2) is substantially equal, and it is possible to suppress, for example, that the effective region T becomes larger than a necessary value in the X-axis direction.

According to the container 40a of the second embodiment described above, even when the container 40 is provided with a plurality of liquid supply ports 480, the effective area T and the effective area can be separated in each liquid supply port 480 and liquid introduction tube 550. The clearance Q in the X-axis direction of S is larger than the clearance S in the Y-axis direction (Q>S). Thus, even if the container 40 has a structure in which dimensional errors are more likely to occur in the X-axis direction than in the Y-axis direction, or the container 40 has a structure in which it is easier to cause dimensional errors in the X-axis direction than in the Y-axis direction when mounted on the holder 51 The structure where there is an error in the mounting position can also make the liquid supply port 480 closely adhere to the liquid introduction tube 550 . As a result, the liquid contained in the container 40 can be stably supplied to the printer 20 .

Even in such a case, a dimensional error or an error in the mounting position is more likely to occur in the X-axis direction than in the Y-axis direction when mounting as follows: for example, in the case 42 When the dimension D in the X-axis direction is larger than the dimension W in the Y-axis direction, or when the container 40 is attached to the holder 51 , it is accompanied by movement in the X-axis direction. Thus, when the container 40 is mounted on the bracket 51 and includes the effective region S inside the effective region T, by making the clearance Q in the X-axis direction between the effective region T and the effective region S larger than the clearance Q in the Y-axis direction, The gap S is large (Q>S), so that the liquid supply port 480 can be well adhered to the liquid introduction pipe 550 .
