Description

[Technical Field]

[0001] The present disclosure relates to a mechanism for attaching a liquid container and a method for stirring ink in an ink cartridge, and more particularly to a mechanism for attaching a liquid container, such as an ink pouch, to an apparatus such as a printer and a method for using the mechanism. [Background technology]

[0002] Patent Document 1 describes a fluid ejection device including a fluid container having a container portion for storing a fluid to be ejected and an outlet port for discharging the fluid contained in the container, a container case for storing the fluid container, a fluid outlet portion for ejecting the fluid toward an object to be ejected, a supply needle having a flow path communicating with the fluid outlet portion, a guard cover protruding to cover the supply needle, a guide for slidably guiding the fluid container to a fixed position where the outlet port is inserted into the supply needle after mating with the fluid container, and a fastening member for fastening the fluid container guided to the fixed position to the container case. The fluid container of this fluid ejection device has an engaging portion formed in the vicinity of the outlet port for engaging with the fastening member, and the guard cover has a through-hole formed at a position corresponding to the engaging portion of the fluid container guided to the fixed position. Furthermore, the fluid injection device described in Patent Document 1 includes a main body housing that houses a fluid ejection unit, and the storage case is pivotally attached to the main body housing so that it can rotate around a rotation axis to open and close, and the fluid container is inclined relative to the inner bottom surface of the storage case at an angle that holds the storage unit from below in the direction of gravity throughout the storage case's closed and open states.

[0003] Patent Document 2 describes an ink container that houses ink packs equipped with ink outlets for discharging the stored ink to the outside. This ink container is configured so that the housed ink packs can be in a first position in which they are tilted so that the ink outlets face downward, and a second position in which the inter-pack gap between the ink packs and the ink container is wider than in the first position. The ink container described in Patent Document 2 also includes a mounting member having a mounting surface on which the ink packs are placed, and the mounting member is movable between a first state in which the mounting surface is tilted relative to the horizontal plane and the ink packs are in the first position, and a second state in which the mounting surface is tilted at a gentler angle relative to the horizontal plane than in the first state and the ink packs are in the second position. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 4952655 [Patent Document 2] Japanese Patent Application Laid-Open No. 2016-196093 Summary of the Invention [Problem to be solved by the invention]

[0005] Patent document 2 features a mechanism for stirring the ink in the ink pack by switching the position of the ink pack between a first position and a second position, with the aim of homogenizing the material concentration in the ink pack when the ink contains a sedimentary pigment, such as white UV ink (see paragraph 0064 of Patent document 2).

[0006] However, as shown in Figure 7 of Patent Document 2, in a configuration in which the ink pack is set in a horizontal position, it is difficult and unrealistic to sufficiently agitate the white ink simply by shaking the ink pack by tilting the mounting member. Also, it is necessary to secure space for the position switching mechanism shown in Figure 7 of Patent Document 2, and costs increase due to the increased number of parts.

[0007] In Patent Document 1, the issue of securing space for a large-capacity ink pack (fluid container) is addressed, and the ink pack is attached to an upper casing, i.e., an upper housing, that moves around a rotation axis. However, Patent Document 1 does not mention ink agitation. Even with the configuration described in Patent Document 1, if the ink pack is set in a lying position, as shown in Figures 2 and 3 of Patent Document 1, it is difficult to sufficiently agitate the white ink, which tends to settle, just by opening and closing the upper casing around the rotation axis.

[0008] For this reason, in actual printing factories, for example, it is common for users to agitate the ink pouches containing white ink used in wide-format (WF) inkjet printers by removing and attaching the ink pouches and shaking them several times every day. This type of agitation is a common practice in the printing industry.

[0009] However, the nozzles of inexpensive ink pouches are made of plastic, and although they can withstand being removed and attached a few times, they are not designed to be removed and attached every day (tens to hundreds of times until the ink is used up), so there is a concern that the nozzle may break and ink may leak into the printer.

[0010] The present disclosure has been made in consideration of these circumstances, and aims to provide an attachment mechanism for a liquid container that can prevent damage to the nozzle and enable efficient stirring, as well as a method for stirring ink in an ink cartridge using that mechanism. [Means for solving the problem]

[0011] An attachment mechanism for a liquid container according to one aspect of the present disclosure includes a holder portion that fixes a nozzle that serves as an outlet for the liquid in the liquid container and holds the liquid container, a set portion having a fitting portion that fits with the nozzle to allow the liquid to flow out of the nozzle, a tube that communicates with the fitting portion, and a main body that is connected to the set portion using the tube, and the set portion is movable relative to the main body.

[0012] According to this aspect, when the nozzle of the liquid container held in the holder section is engaged with the fitting portion of the set section, the holder section and the set section can be moved together relative to the main body, thereby preventing damage to the nozzle and enabling efficient stirring.

[0013] In the attachment mechanism for a liquid container according to another aspect of the present disclosure, the setting portion may be detachable from the main body within a range that the tube can reach.

[0014] In an attachment mechanism for a liquid container according to another aspect of the present disclosure, the set portion may be connected to the main body via a first rotation axis, and the set portion may be rotatable relative to the main body around the first rotation axis.

[0015] In the attachment mechanism for a liquid container according to another aspect of the present disclosure, the rotation direction of the setting part about the first rotation shaft may be the up-down direction.

[0016] In the attachment mechanism for a liquid container according to another aspect of the present disclosure, it is preferable that the direction of the smallest dimension among the length, width, and thickness directions of the liquid container is parallel to the first rotation axis.

[0017] In an attachment mechanism for a liquid container according to another aspect of the present disclosure, when the length direction of the liquid container parallel to the orientation of the nozzle is defined as a first direction, the width direction of the liquid container perpendicular to the first direction is defined as a second direction, and the thickness direction of the liquid container perpendicular to the first and second directions is defined as a third direction, and the length of the liquid container in the first direction is defined as L1, the width of the liquid container in the second direction is defined as L2, and the thickness of the liquid container in the third direction is defined as L3, the relationship L1>L2>L3 is satisfied, and the first rotation axis may be configured to be parallel to the third direction.

[0018] In an attachment mechanism for a liquid container according to another aspect of the present disclosure, the holder portion may be connected to the set portion via a second rotation axis, and the holder portion may be rotatable relative to the set portion around the second rotation axis.

[0019] In the attachment mechanism for a liquid container according to another aspect of the present disclosure, the direction of rotation of the holder part about the second rotation shaft may be vertical.

[0020] In the mounting mechanism for a liquid container according to another aspect of the present disclosure, it is preferable that the nozzle and the fitting portion are fitted together by rotating the holder portion holding the liquid container around the second rotation axis.

[0021] In the attachment mechanism for the liquid container according to another aspect of the present disclosure, the first rotation axis and the second rotation axis are preferably configured to be parallel to each other.

[0022] In the mounting mechanism for a liquid container according to another aspect of the present disclosure, it is preferable to have an avoidance mechanism that avoids simultaneous rotational movement of the set part relative to the main body by the first rotation axis and rotational movement of the holder part relative to the set part by the second rotation axis.

[0023] In an attachment mechanism for a liquid container according to another aspect of the present disclosure, the avoidance mechanism may be configured to selectively realize a first state in which rotational movement of the set part relative to the main body by the first rotation axis is inhibited and rotational movement of the holder part relative to the set part by the second rotation axis is permitted, and a second state in which rotational movement of the set part relative to the main body by the first rotation axis is permitted and rotational movement of the holder part relative to the set part by the second rotation axis is inhibited.

[0024] In an attachment mechanism for a liquid container according to another aspect of the present disclosure, the avoidance mechanism may include a connecting member that selectively integrates the setting portion with either the main body or the holder portion, and the connecting member may be configured to be movable between a first position where it engages with the main body to achieve a first state, and a second position where it engages with the holder portion to achieve a second state.

[0025] In the attachment mechanism for a liquid container according to another aspect of the present disclosure, the connecting member may be configured to be rotatably supported by the setting portion via a third rotation shaft.

[0026] In the mounting mechanism for a liquid container according to another aspect of the present disclosure, it is preferable that the avoidance mechanism be configured to be able to switch, with a single operation, between a state in which the set section can be rotated relative to the main body by the first rotation axis and a state in which the holder section can be rotated relative to the set section by the second rotation axis.

[0027] In the attachment mechanism for a liquid container according to another aspect of the present disclosure, the liquid may be ink, and the liquid container may be a pouch-shaped ink cartridge.

[0028] In the attachment mechanism for a liquid container according to another aspect of the present disclosure, the liquid may be a white ink containing a white pigment.

[0029] In the attachment mechanism for the liquid container according to another aspect of the present disclosure, the mouthpiece may be made of plastic.

[0030] A method of stirring ink in an ink cartridge according to another aspect of the present disclosure includes using an ink cartridge mounting mechanism that includes: a holder portion that fixes the nozzle, which serves as the ink outlet of the ink cartridge containing ink, and holds the ink cartridge; a set portion having a fitting portion that fits with the nozzle to allow ink to flow out of the nozzle; a tube that communicates with the fitting portion; and a main body that is connected to the set portion using the tube and receives a supply of ink via the tube, and includes engaging the nozzle and the fitting portion while the ink cartridge is held in the holder portion; and moving the holder portion and the set portion together relative to the main body while the nozzle and the fitting portion are fitted together, thereby stirring the ink inside the ink cartridge. [Effects of the Invention]

[0031] According to the present invention, damage to the nozzle of the liquid container can be suppressed, and the liquid inside the liquid container can be efficiently stirred. [Brief explanation of the drawings]

[0033] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0034] <<Example of an ink pouch>> FIG. 1 is a perspective view showing an example of an ink pouch 10. The ink pouch 10 includes a sealed bag 12 that stores ink, and a nozzle 14 that serves as an ink outlet for allowing the ink to flow out of the sealed bag 12. The sealed bag 12 is made of a flexible material. The nozzle 14 may be made of plastic. The ink stored in the ink pouch 10 of this example is, for example, a white ink containing a white pigment. The white pigment may be, for example, an ink containing titanium oxide. The ink may also be an ultraviolet (UV) curable ink.

[0035] The ink pouch 10 is an ink cartridge used in a printing device (not shown). The printing device may be, for example, an inkjet printer, and as an example, may be a wide-format UV inkjet printer. The ink pouch 10 is attached to the printing device, and the printing device receives a supply of ink from the ink pouch 10 to perform printing. The ink pouch 10 is an example of a "liquid container" and a "pouch-shaped ink cartridge" in this disclosure.

[0036] <Configuration of ink pouch mounting mechanism> 2 to 4 are perspective views showing the configuration of the mounting mechanism 20 for the ink pouch 10 according to the embodiment. Fig. 2 shows the state during printing. Fig. 3 shows the state when the ink pouch 10 is set. Fig. 4 shows the state when the ink is being stirred.

[0037] The mounting mechanism 20 for the ink pouch 10 includes a holder section 22 that houses the ink pouch 10, and a setting section 24 that connects the holder section 22 to a main body 30. The main body 30 may be part of the main body of the printing device. The holder section 22 is a case that surrounds at least a portion of the ink pouch 10. The holder section 22 may have an open surface for inserting and removing the ink pouch 10, or may have an openable box-like structure.

[0038] The set part 24 is an intervening connecting part disposed between the holder part 22 and the main body 30, and functions as a mounting base for the holder part 22. The holder part 22 is configured to be connected to the main body 30 via the set part 24. The holder part 22 and the set part 24 are each configured to be movable relative to the main body 30 (see Figures 3 and 4), and the set part 24 and the main body 30 are connected using a long, thin piping tube 34 (see Figure 4).

[0039] In this embodiment, the setting unit 24 and the main body 30 are connected via a first rotation shaft 40, and the setting unit 24 is rotatable relative to the main body 30 around the first rotation shaft 40. In addition, the holder unit 22 and the setting unit 24 are connected via a second rotation shaft 42, and the holder unit 22 is rotatable relative to the setting unit 24 around the second rotation shaft 42.

[0040] As shown in Figure 2, when the ink pouch 10 is set in an upright position with the nozzle 14 of the ink pouch 10 facing downward in the direction of gravity, it is preferable that the axial directions of the first rotation shaft 40 and the second rotation shaft 42 are parallel to a direction perpendicular to the direction of gravity (horizontal direction).

[0041] In this example, the holder section 22 is rotatable in the vertical direction around the second rotation shaft 42 (see FIG. 3), and the setting section 24 is rotatable in the vertical direction around the first rotation shaft 40 (see FIG. 4).

[0042] As shown in Fig. 3, the holder part 22 is provided with a groove 23 for restricting (restraining) the position of the mouthpiece 14 when holding the ink pouch 10 (see Fig. 3). A recess 15 that engages with the edge of the groove 23 is formed on the outer periphery of the mouthpiece 14 (see Fig. 1), and by engaging the recess 15 on the outer periphery of the mouthpiece 14 with the edge of the groove 23 and inserting the mouthpiece 14 into the groove 23, the mouthpiece 14 is positioned at the end of the non-open side of the groove 23. The groove 23 functions as a mouthpiece fixing part that fixes the mouthpiece 14 at a specific position on the holder part 22.

[0043] The setting unit 24 is provided with a fitting portion 28 that fits into the mouthpiece 14 of the ink pouch 10 (see FIG. 3). The fitting portion 28 is a flow path connector that fits into the mouthpiece 14 to form an ink flow path. For example, the fitting portion 28 may be structured so that it functions as a male coupler and the mouthpiece 14 functions as a female coupler (socket). The fitting portion 28 may also have a hollow needle-like structure that is inserted into the mouthpiece 14. By rotating the holder unit 22 holding the ink pouch 10 around the second rotation axis 42 toward the setting unit 24 as shown in FIG. 3, the mouthpiece 14 fixed to the holder unit 22 and the fitting portion 28 of the setting unit 24 fit together, and the mouthpiece 14 and the fitting portion 28 are connected.

[0044] The fitting portion 28 communicates with the tube 34. That is, one end of the tube 34 is connected to the fitting portion 28, and the other end of the tube 34 is connected to the main body 30. The tube 34 is preferably a flexible soft tube. For example, a super flexible fluorine tube having a three-layer structure with an inner layer made of fluorine tube, a middle layer made of polyamide, and an outer layer made of polyurethane can be suitably used as the tube 34. The tube 34 may also be a silicone tube or the like. The main body 30 receives a supply of ink from the ink pouch 10 via the tube 34.

[0045] 4, when stirring the white ink inside the ink pouch 10, the holder part 22 and the setting part 24 to which the ink pouch 10 is attached are rotated as a unit around the first rotation shaft 40, and the ink pouch 10 together with the "holder part 22 and setting part 24" is shaken within the range of the tube 34. This rotational movement allows the white ink inside the ink pouch 10 to be sufficiently stirred.

[0046] According to the attachment mechanism 20 for the ink pouch 10 of this embodiment, the ink pouch 10 can be shaken while the mouthpiece 14 of the ink pouch 10 held in the holder portion 22 is connected to the fitting portion 28 of the setting portion 24. Therefore, once the ink pouch 10 is housed in the holder portion 22 and set in the setting portion 24, there is no need to attach or detach the mouthpiece 14 until the ink is used up. In other words, the fitting operation for the mouthpiece 14 can be limited to one time. This prevents damage to the mouthpiece 14 and also prevents ink leakage.

[0047] 2 to 4 illustrate an example of a double-hinge type rotational movement mechanism including a first rotational shaft 40 and a second rotational shaft 42. However, it is also possible to omit at least one of the first rotational shaft 40 and the second rotational shaft 42 and to configure at least one of the holder portion 22 and the setting portion 24 to be separable from the main body 30. By configuring the holder portion 22 and the setting portion 24 to be separable, the holder portion 22 can be freely moved when attaching or detaching the ink pouch 10. Furthermore, by configuring the setting portion 24 and the main body 30 to be separable within the constraints of the tube 34, the integrated body of the holder portion 22 and the setting portion 24 holding the ink pouch 10 can be freely moved within the range of movement of the tube 34 when stirring the ink, thereby stirring the ink.

[0048] On the other hand, if a structure is adopted that allows the holder part 22 and the setting part 24 to be detached from the main body 30 and moved freely, there is a concern that handling of the piping tube 34 that connects the setting part 24 and the main body 30 will become complicated. For this reason, as exemplified in Figures 2 to 4, it is preferable to use a structure including a first rotation shaft 40 and a second rotation shaft 42, or the like, that restricts the range of movement of the holder part 22 and the setting part 24, while ensuring ease of operation and stirring when attaching and detaching the ink pouch 10 and stirring the ink.

[0049] In this embodiment, in order to ensure sufficient stirring of the white ink, the rotation angle by which the setting section 24 can be rotated around the first rotation axis 40 is preferably 90 degrees or more, and more preferably 130 degrees or more.

[0050] <<About the simultaneous movement avoidance mechanism>> As described above, the mounting mechanism 20 of the ink pouch 10 in this embodiment is structured so that the holder portion 22 and the set portion 24, while holding the ink pouch 10, can move together relative to the main body 30, allowing the ink pouch 10 to be shaken to stir the ink while maintaining the mating connection between the nozzle 14 and the mating portion 28.

[0051] On the other hand, in a double hinge system equipped with a first rotating shaft 40 and a second rotating shaft 42, if a configuration is adopted that simultaneously allows rotational movement of the set section 24 by the first rotating shaft 40 and rotational movement of the holder section 22 by the second rotating shaft 42, there is a concern that force may be unintentionally applied to the fitting connection between the nozzle 14 and the fitting section 28 during the ink stirring operation, causing the fitting to loosen or the fitting section 28 to come off the nozzle 14, resulting in ink splashing.

[0052] To avoid such a situation, it is preferable that the mounting mechanism 20 of the ink pouch 10 is configured to have a simultaneous movement avoidance mechanism that avoids simultaneous rotational movement (rotational movement) of the set portion 24 by the first rotational shaft 40 and the holder portion 22 by the second rotational shaft 42.

[0053] 5 and 6 are schematic diagrams showing examples of the simultaneous movable avoidance mechanism 50. 5 1 shows the state when the ink pouch 10 is attached or detached, and FIG. 6 The simultaneous movement avoidance mechanism 50 is in a first state (FIG. 1) in which the rotational movement of the set part 24 relative to the main body by the first rotation shaft 40 is inhibited and the rotational movement of the holder part 22 relative to the set part 24 by the second rotation shaft 42 is permitted. 5 ) and a second state (see FIG. 1 ) in which rotational movement of the set part 24 relative to the main body 30 by the first rotation shaft 40 is permitted and rotational movement of the holder part 22 relative to the set part 24 by the second rotation shaft 42 is inhibited. 6 This is a mechanism that selectively realizes the following:

[0054] The simultaneous movement avoidance mechanism 50 includes a rotary connecting member 52. The connecting member 52 is an L-shaped member having a first arm 54 and a second arm 56, and the intersection of the L shape is supported by the setting unit 24 via a third rotation shaft 58. When attaching or detaching the ink pouch 10, as shown in FIG. 5 1, an engaging portion 55 provided at the tip of a first arm 54 of a connecting member 52 engages with an engaged portion 35 provided on the main body 30 side, whereby the first arm 54 is connected to the main body 30, and the setting portion 24 and the main body 30 are integrated via the first arm 54. At this time, the second arm 56 is not engaged with the holder portion 22.

[0055] That is, Fig. 5 As shown in FIG. 1, when the first arm 54 is connected to the main body 30, the setting unit 24 is constrained to the main body 30. 5 In the state shown in FIG. 1, the setting portion 24 is prevented from rotating about the first rotation shaft 40 and cannot be rotated. On the other hand, the holder portion 22 can be rotated about the second rotation shaft 42, and the ink pouch 10 can be attached or detached by moving the holder portion 22. The engaging portion 55 and the engaged portion 35 may be connected mechanically or by using magnetic force. The same applies to the engaging portion 57 and the engaged portion 59 described below.

[0056] When stirring the ink, 5 The connecting member 52 is rotated 90 degrees counterclockwise from the state shown in FIG. 6 The state shown in FIG. 1 is achieved by one operation (one motion) of rotating the connecting member 52 by 90 degrees. 5 State and diagram 6 Since the state can be switched between the above two states, the operation of selectively switching the state is simple.

[0057] figure 61, an engaging portion 57 provided at the tip of the second arm 56 of the connecting member 52 engages with an engaged portion 59 provided on the holder portion 22 side, whereby the second arm 56 is connected to the holder portion 22, and the setting portion 24 and the holder portion 22 are integrated via the second arm 56. At this time, the first arm 54 is not engaged with the main body 30.

[0058] That is, Fig. 6 As shown in FIG. 1, when the second arm 56 is connected to the holder part 22, the holder part 22 is restrained by the setting part 24. 6 In this state, the holder part 22 and the setting part 24 can be rotated together around the first rotation shaft 40, making it possible to agitate the ink. On the other hand, the holder part 22 is prevented from rotating about the second rotation shaft 42, making it impossible to move (rotate) the holder part 22 relative to the setting part 24. This makes it difficult for unnecessary force to be applied to the mating connection between the nozzle 14 and the mating part 28, making it possible to suppress the scattering of ink during agitation.

[0059] The simultaneous movable avoidance mechanism 50 is an example of the "avoidance mechanism" in this disclosure. 5 The rotational position of the connecting member 52 shown in FIG. 6 The rotational position of the connecting member 52 shown in FIG. 1 is an example of the "second position" in the present disclosure. 5 and Figure 6 Although a rotary type connecting member 52 has been exemplified, a sliding type connecting member may also be used.

[0060] <About the axial direction of the rotation axis> The axial directions of the first rotating shaft 40 and the second rotating shaft 42 are preferably designed based on the shape of the ink pouch 10. From the viewpoint of improving the agitation properties of the ink, it is desirable that the direction in which the integrated structure of the "holder part 22 and the setting part 24" rotates relative to the main body 30 during ink agitation is a direction in which the long axis of the ink pouch 10 swings significantly.

[0061] The long axis of the ink pouch 10 referred to here is the longitudinal axis of the shape of the ink pouch 10, and the longest dimension among the length direction (vertical direction), width direction (horizontal direction), and thickness direction (depth direction) of the ink pouch 10 may be called the long axis. In this example, the length direction parallel to the orientation of the nozzle 14 of the ink pouch 10 corresponds to the long axis. The orientation of the nozzle 14 refers to the direction in which ink flows out of the nozzle 14.

[0062] If the vertical length of the ink pouch 10 is L1, the width is L2, and the thickness is L3, then the ink pouch 10 of this example satisfies the relationship L1>L2>L3. It is preferable that the first rotation axis 40 is configured to be parallel to the direction of the smallest dimension (here, the thickness direction) among the various directions. The length direction (vertical direction), width direction (lateral direction), and thickness (depth direction) directions of the ink pouch 10 are examples of the "first direction," "second direction," and "third direction" in this disclosure, respectively.

[0063] For ease of explanation, the following description will be given by defining the x-axis, y-axis, and z-axis as orthogonal coordinate axes as shown in FIG. 2. Here, the z-axis is assumed to be parallel to the direction of gravity. In FIG. 2, the long axis of the ink pouch 10 is arranged parallel to the z-axis direction. In FIG. 2, the width direction of the ink pouch 10 is the x-axis direction, and the thickness direction is the y-axis direction. In order to swing the long axis of the ink pouch 10 widely, the axial direction of the first rotation shaft 40 is not limited to being parallel to the y-axis direction, but may also be parallel to the x-axis direction.

[0064] However, when a printing device uses ink packs of multiple colors, such as cyan, magenta, yellow, and black, in addition to white ink, the ink packs of the other colors may be arranged side by side, for example, in the y-axis direction of Fig. 2. In such a case, if the setting unit 24 is rotated around a rotation axis parallel to the x-axis, it may interfere with adjacent ink packs, or it may be necessary to secure a large space for rotational movement. Therefore, Figs. 2- 6As explained in the above, it is more desirable to configure the first rotation axis 40 to be parallel to the y-axis. The same applies to the second rotation axis 42, and it is desirable that the second rotation axis 42 and the first rotation axis 40 are parallel to each other.

[0065] Advantages of this embodiment According to the attachment mechanism 20 of the ink pouch 10 and the ink stirring method using the same according to this embodiment, damage to the nozzle 14 can be suppressed, and efficient ink stirring is possible.

[0066] Other application examples In the above embodiment, an example was described in which white ink was stirred, but the technology disclosed herein is not limited to an attachment mechanism for an ink pouch 10 containing white ink, and can be applied as a mechanism for attaching various types of liquid containers that contain liquids that require stirring.

[0067] <Combinations of embodiments and modifications> The configurations described in the above embodiments and the features described in the modified examples can be used in appropriate combinations, and some features can also be replaced.

[0068] "others" The present disclosure is not limited to the above-described embodiments, and various modifications are possible within the scope of the gist of the technical idea of ​​the present disclosure. [Explanation of symbols]
