Description

[Technical Field]

[0001] The present invention relates to a binder and a file. [Background technology]

[0002] Some files are equipped with rings for binding paper sheets (e.g., writing paper). For example, there is a ring notebook that uses a single spirally extending wire ring that is inserted into multiple holes formed in the cover and writing paper. If the ring is made of metal or a hard resin material, it can interfere with writing. There is also concern that the ring may put pressure on the hand when writing. To solve this problem, for example, Patent Document 1 discloses a ring notebook that has rings made of a flexible material that is flexible enough to be deformed freely when a predetermined pressure is applied. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2000-141973 Summary of the Invention [Problem to be solved by the invention]

[0004] For example, the ring notebook described in Patent Document 1 has binding rings made of a soft material, which means that the binding rings are less likely to put pressure on the hand and make writing easier than when the binding rings are made of metal or hard resin material. However, with the ring notebook described in Patent Document 1, for example, the cover and writing paper that are bound by the binding rings cannot be replaced.

[0005] In view of the above problems, the present invention aims to provide a binder or file that allows for interchangeable paper and covers, puts less strain on the hands, and is easy to write in. [Means for solving the problem]

[0006] In order to solve the above problem, a binding device for binding papers etc. is made of a deformable material, and by deforming it can be inserted and removed through binding holes of papers etc. In detail, the binding device according to the present invention is a binding device for binding objects including at least one of paper and a cover, and is made of a deformable material, and includes a support part that is inserted into the binding holes of the objects to be bound to support the objects to be bound in a bound state in which the objects to be bound are bound, and an insertion and removal part that appears when the binding device is deformed and can be inserted and removed freely through the binding holes in a replacement state in which the objects to be bound are replaced.

[0007] The binding device according to the present invention has an inlet / outlet section where the binding device deforms to appear, allowing the bound object, such as paper or cover, to be replaced. In addition, the binding device according to the present invention has a support section that supports the bound object made of a deformable material, which reduces pressure on the hand and makes writing easier.

[0008] The object to be bound includes at least one of paper and a cover. The paper is, for example, writing paper. The cover includes at least one of a front cover and a back cover. The binding device can be made of a deformable material, for example, resin. The binding device is deformable and has a bound state in which the object to be bound is bound, and a replacement state in which the object to be bound is replaced. In the bound state, the area constituting the binding device is continuous and annular. In the replacement state, a discontinuous area such as a gap is formed in part of the area constituting the binding device. In the bound state, the area constituting the binding device is continuous and annular, and the support part is inserted into the binding hole of the object to be bound and supports the object to be bound at the continuous area. In other words, the support part supports the object to be bound with a surface. There may be one or more binding holes. The in / out portion is a discontinuous area such as a gap that appears when the binding device is deformed in the replacement state. The in / out portion appears in the replacement state and does not appear in the bound state. The in / out portion is a discontinuous area such as a gap that appears in the replacement state and can be freely inserted into and removed from the binding hole.

[0009] Here, the support portion is cylindrical in the binding state and has a discontinuous portion that becomes a discontinuous area in the replacement state, and when the binding device is deformed in the replacement state, an in / out portion appears in the discontinuous portion as a gap that can be freely inserted and removed from the binding hole.

[0010] The binding tool can be freely inserted into and removed from the binding hole through the inlet / outlet portion, which serves as a gap that appears in the discontinuous portion. As a result, the binding tool can freely replace the object to be bound. The discontinuous portion is a notch or the like that is discontinuous in the replacement state and continuous in the bound state.

[0011] The discontinuous portion may be formed in a spiral shape. The in / out portions can be formed at both ends of the discontinuous portion. When removing the binding device from the binding holes, the binding device is removed from the binding holes through the gap as one of the in / out portions, and when the binding device is rotated, the support by the support portions is gradually released. In other words, the binding device moves away from the binding holes. By continuing to rotate the binding device, the support by the support portions is completely released. In other words, the binding device can be removed from the binding holes. When attaching the binding device to the binding holes (when binding objects with the binding device), the reverse operation to the above is performed. Specifically, when attaching the binding device to the binding holes, the binding hole is inserted into the gap as one of the in / out portions, and when the binding device is rotated, the binding hole is gradually supported by the support portions. In other words, the binding device is fastened to the binding holes. By continuing to rotate the binding device, the binding hole support is supported by the support portions. In other words, the object to be bound can be bound by the binder. The discontinuous portion may be, for example, linear, as long as it can form a discontinuous area in the replacement state.

[0012] Moreover, the binding device according to the present invention may further include a movement restricting portion that restricts movement of the binding device relative to the binding holes in the bound state.

[0013] In the bound state, there is a risk that the edge of the binding hole may enter the entry / exit portion. If the edge of the binding hole enters the entry / exit portion, the bound object may move up and down, making it impossible to bind the bound object in the proper position. Furthermore, if the edge of the binding hole enters the entry / exit portion further, there is a risk that the bound state may be released. The binding device according to the present invention is provided with a movement restriction portion, thereby restricting the movement of the binding device. In detail, the edge of the binding hole is prevented from entering the entry / exit portion, making it possible to bind the bound object in the proper position. Furthermore, since the edge of the binding hole is unlikely to enter the entry / exit portion, the bound state is not released.

[0014] The movement restricting portion may be a thin-plate-shaped flag portion provided near the entrance / exit portion and protruding outward from the surface of the binding device.

[0015] The binding device according to the present invention is provided with a flag portion, thereby restricting rotation. As a result, the edge of the binding hole is prevented from entering the inlet / outlet portion. In addition, by preventing the edge of the binding hole from entering the inlet / outlet portion, the bound object can be bound at the appropriate position. The flag portion can be provided on at least one of the ends of the discontinuous portion. By providing it on both ends, rotation of the binding device can be more effectively restricted. The movement restricting portion is not limited to a flag portion as long as it can restrict movement of the binding device relative to the binding hole in the bound state.

[0016] Here, the present invention may be specified as a file including a bound body and a binding device. In detail, the present invention is a file including a bound body including at least one of paper and a cover, and a binding device that binds the bound body, the binding device being made of a deformable material, and including: a support portion that is inserted into the binding hole of the bound body to support the bound body in a bound state in which the bound body is bound; and an inlet / outlet portion that appears when the binding device is deformed and can be freely inserted into and removed from the binding hole in a replacement state in which the bound body is replaced.

[0017] The file of the present invention has an entrance / exit section where the binding device deforms and appears, allowing the bound object, such as paper or cover, to be replaced. Also, the support section of the file of the present invention that supports the bound object is made of a deformable material, so it puts less pressure on the hand and is easy to write in.

[0018] In the file according to the present invention, the object to be bound may have binding holes, and the binding holes may include elongated holes having a length from one end to the other end of the binding tool.

[0019] In the file according to the present invention, the object to be bound has a long hole as a binding hole, so that the contact area between the support part and the binding hole is increased, compared to when the binding hole at the same position is configured by arranging multiple holes that are shorter in the longitudinal direction than the long hole, and the object to be bound can be bound more stably. Also, compared to when the long hole is configured by multiple holes, it is easier to replace the object to be bound.

[0020] The long holes may be provided near one end and the other end of the object to be bound.

[0021] By providing long holes as binding holes near one end and the other end of the bound body, the binding device is also provided near one end and the other end of the bound body. In other words, there is no need to provide the binding device near the center of the bound body. As a result, the hand is less likely to come into contact with the binding device, which reduces pressure on the hand and makes writing easier. [Effects of the Invention]

[0022] According to the present invention, it is possible to provide a binder or file that allows for interchangeable paper and covers, puts less strain on the hands, and is easy to write in. [Brief explanation of the drawings]

[0024] Next, an embodiment of the binder and file according to the present invention will be described with reference to the drawings. In this specification, unless otherwise specified, "top," "bottom," "left," and "right" refer to the top, bottom, left, and right as seen in Figure 1. The following description is an example, and the present invention is not limited to the following content.

[0025] First Embodiment <Configuration> As shown in FIGS. 1 to 3, the file 1 according to the first embodiment includes a bound body 2 and a binder 5. The bound body 2 includes writing paper 23 (an example of paper according to the present invention), a front cover 21, and a back cover 22. The writing paper 23 is a type of paper known as loose-leaf paper. The writing paper 23 is a rectangle that is long in the vertical direction, and a plurality of binding holes 6 are provided linearly at predetermined intervals near one of the long sides. The binding holes 6 include a regular hole 62 and an elongated hole 61. The regular hole 62 is substantially square and is provided near one of the long sides and in a portion (near the center) excluding both ends. The regular hole 62 may have another shape, such as a rectangle or a substantially circle. The elongated hole 61 is a rectangle that is long in the vertical direction and has a length from one end to the other end of the longitudinal direction (vertical direction) of the binder 5, and is provided near one end and the other end of the bound body 2. The slot 61 is provided on one long side of the slot 61 and has a slot projection 61a that protrudes inward and a slot recess 61b that is continuous with the slot projection 61a. In this embodiment, the slot projections 61a are provided in two locations at a fixed interval (the same interval as the regular holes 62). The slot recesses 61b are provided in three locations at a fixed interval (the same interval as the regular holes 62). The slot projections 61a and the slot recesses 61b are provided on the long side of the two long sides of the slot 61 that does not have the binding holes 6 of the object 2. The binding holes 6 may have a simpler configuration by omitting the regular holes 62. On the other hand, a configuration including the regular holes 62 allows use with conventional filing tools, thereby increasing versatility. The binding holes 6 may have other shapes, such as a circle. The elongated hole 61 may have the protruding portion 61a and the recessed portion 61b on the other long side or on both long sides. Also, the elongated hole 61 may have a simpler configuration by omitting the protruding portion 61a and the recessed portion 61b.

[0026] The front cover 21 and back cover 22 cover the writing paper 23. The front cover 21 and back cover 22 are rectangular and formed to fit the shape of the writing paper 23, and are slightly larger than the writing paper 23. The front cover 21 and back cover 22 may be the same size as the writing paper. The front cover 21 and back cover 22 according to this embodiment are made of transparent resin, allowing the lines of the writing paper 23 to be seen through. The front cover 21 and back cover 22 may be made of opaque resin, or may be made of other materials such as paper. The front cover 21 and back cover 22 have a plurality of linear binding holes 6 spaced at predetermined intervals near one long side to correspond to the binding holes 6 of the writing paper 23. The binding holes 6 have regular holes 62 and elongated holes 61, just like the writing paper 23. The regular holes 62 and elongated holes are similar to those of the writing paper 23, and therefore will not be described here.

[0027] 4 to 12 show the binding device 5 according to the first embodiment. The binding device 5 includes a support portion 51, a discontinuous portion 54, an in / out portion 52, and flag portions 53a and 53b as movement restricting portions 53.

[0028] The binding device 5 is made of a deformable resin, and has a bound state in which the object 2 is bound, as shown in Figs. 1 to 4 and 12, and a replacement state in which the object 2 is replaced, as shown in Figs. 5 to 11. In the binding state, the area constituting the binding device 5 is continuous and annular, more specifically, cylindrical. In the replacement state, the binding device 5 has a gap as a discontinuous area, more specifically, a discontinuous portion 54, formed in part of the area constituting the binding device.

[0029] In the bound state, the support portion 51 has a continuous cylindrical region that constitutes the binding device 5, and contacts the binding holes 6 of the bound body 2 to support the bound body 2 in the continuous region. In other words, the support portion 51 supports the bound body 2 on a surface.

[0030] The discontinuous portion 54 is composed of a spirally formed notch. In the bound state, the adjacent edges of the notch are in contact with each other and are continuous, but in the replacement state, the binding device 5 is deformed, for example, when a force is applied in the vertical direction, and the discontinuous portion 54 becomes a discontinuous region.

[0031] The inlet / outlet portion 52 is formed as a gap formed at both ends of the discontinuous portion 54. The inlet / outlet portion 52 appears as a gap that can be freely inserted and removed from the elongated hole 61 serving as the binding hole 6 when the binding device is deformed, for example, when a force is applied in the vertical direction or when a force is applied so as to pull apart the ends of the discontinuous portion 54. The inlet / outlet portion 52a (lower side in FIG. 6 ) located on the center side of the bound body 2 is formed as a linear cutout parallel to the central axis of the binding device 5 and is provided at a position overlapping with the central axis of the binding device 5 in a side view. The inlet / outlet portion 52a is an end of the linear cutout and has a triangular cutout portion 52a1 at the end on the center side of the bound body 2. The triangular cutout portion 52a1 functions as a relief that suppresses interference between the binding device 5 and the end of the bound body 2, for example, when using the file 1 (when turning over the bound body 2). In addition, the triangular cutout portion 52a1 can make it easier to insert and remove the binding hole 6. The in / out portion 52b (upper side in FIG. 6) located on the end side of the bound body 2 is made of a linear cutout parallel to the central axis of the binding device 5, and is provided at a position eccentric to the central axis of the binding device 5 in side view. On both sides of the linear cutout as the in / out portion 52b, flag portions 53a and 53b are provided as the movement restricting portion 53. Conversely, the in / out portion 52a may be provided at a position eccentric to the central axis of the binding device 5 in side view, and the in / out portion 52b (upper side in FIG. 6) may be provided at a position overlapping with the central axis of the binding device 5 in side view.

[0032] The flag portions 53a and 53b serving as the movement restricting portion 53 restrict movement of the binding device 5 relative to the binding holes 6 in the bound state. The flag portions 53a and 53b are provided near the entrance / exit portion 52b and are made of plate-like portions that protrude outward from the surface of the binding device 5. The flag portions 53a and 53b include the flag portion 53a (on the right side in FIG. 6) and the flag portion 53b (on the left side in FIG. 6). The flag portion 53b is formed to be slightly larger than the flag portion 53a, but the flag portion 53a may also be formed to be slightly larger than the flag portion 53b.

[0033] <How to use> Next, a method for using the binder 5 and the file 1 will be described. The following method of use is an example, and the order of steps can be changed as appropriate. In the following explanation, an example will be given in which the binder 5 is fastened to the long hole 61 on the top side of the file 1.

[0034] First, a description will be given of the case where the binding device 5 is attached to the file 1. Fig. 8 shows the file 1 equipped with the binding device 5 according to the first embodiment in use, with the binding device 5 removed from the bound body 2. The bound body 2 has the front cover 21, writing paper 23, and back cover 22 arranged in this order from the top, with the inside of the front cover 21 positioned at the top.

[0035] FIG. 9 shows a state in which the file 1 including the binding device 5 according to the first embodiment is in use, and shows a state in which the inlet / outlet portion 52 of the binding device 5 begins to be inserted into the elongated hole 61 of the object to be bound 2. The binding device 5 is deformed, and the inlet / outlet portion 52a of the binding device 5 appears (a gap is created), and the inlet / outlet portion 52a is inserted below the elongated hole 61. That is, in this inserted state, the inlet / outlet portion 52a is located on the opposite side of the object to be bound 2 visible in FIG. 9, and is therefore not shown here. More specifically, the edge portion 61c of the elongated hole formed between the long side of the object to be bound 2 and the elongated hole 61 is inserted into the inlet / outlet portion 52a. Next, the binding device 5 is rotated clockwise around its axis when the binding device 5 is viewed from above in a plan view (the same applies hereinafter in this specification) (the arrows in FIGS. 9 and 10 indicate the direction of rotation). As the binding device 5 rotates, the edge 61c of the slot gradually advances toward the upper side of the binding device 5 along the spiral discontinuous portion .

[0036] 10 and 11 show a state in which a file equipped with the binding device according to the first embodiment is in use, with the binding device 5 rotated. As the binding device 5 rotates, the edge 61c of the slot gradually moves upward along the spiral discontinuous portion 54 of the binding device 5. As the binding device 5 continues to rotate, the flag portions 53a and 53b come into contact with a position in the vicinity of the upper side of the slot 61 on the object 2 to be bound, restricting the rotation. The binding device 5 is deformed so that the flag portion 53a (the rear side in FIG. 11) of the flag portions 53a and 53b is positioned on the rear side of the object 2 to be bound. Next, the flag portion 53a is passed through the slot 61 from the rear side of the binding device, and the flag portions 53a and 53b are positioned on the uppermost surface of the object 2 to be bound, and the edge 61c of the slot fits inside the tubular binding device 5 (see FIG. 12). As a result, the support portion 51 comes into contact with the long hole 61 of the object 2 to be bound, and the object 2 to be bound is supported.

[0037] Next, a case where the binding device 5 is removed from the file 1 will be described. First, the binding device 5 is deformed, and of the flag portion 53a and flag portion 53b located on the top surface of the binding body 2, the flag portion 53a (on the rear side in FIG. 11 ) is passed through the elongated hole 61 so that the flag portion 53a is located on the rear side of the bound body 2. Next, the binding device 5 is rotated counterclockwise when viewed from above. As the binding device 5 rotates, the binding device 5 gradually comes out of the elongated hole 61. As the rotation of the binding device 5 continues, the binding device 5 eventually comes out completely from the elongated hole 61. Note that the clockwise and counterclockwise relationship in the attachment and detachment operation of the binding device 5 described above may be reversed. In other words, the binding device 5 may be configured so that when it is rotated counterclockwise when viewed from above, the insertion and removal portion 52 enters the elongated hole 61 of the bound body 2, and when it is rotated clockwise, the binding device 5 comes out of the elongated hole 61.

[0038] <Effects> In the file 1 equipped with the binding device 5 according to the first embodiment, the binding device 5 is made of a deformable resin, and the binding object 2 can be freely replaced by including the discontinuous portion 54 and the in-and-out portion 52. More specifically, the edge portion 61c of the slot can be freely inserted and removed from the in-and-out portion 52, which serves as a gap that appears at the end of the discontinuous portion 54, which is a slit. By inserting the edge portion 61c of the slot into the in-and-out portion 52 and rotating the binding device 5, the edge portion 61c of the slot advances along the spiral discontinuous portion 54, making it possible to attach the binding device 5 to or remove the binding device 5 from the slot 61. In other words, the binding device 5 allows the binding object 2 to be freely replaced. Furthermore, because the binding device 5 according to the first embodiment is made of a deformable resin, it puts less pressure on the hand and is easy to write on.

[0039] Furthermore, the binding device 5 according to the first embodiment is provided with a movement restricting portion 53, which can restrict movement of the binding device 5. Specifically, in the bound state, the binding device 5 is restricted from rotating so that the edge portion 61c of the binding hole enters the in-and-out portion 52, thereby binding the bound object 2 at the appropriate position. Furthermore, since the edge portion 61c of the elongated hole does not easily enter the in-and-out portion 52, the bound state is not released. In the binding device 5 according to the first embodiment, the movement restricting portion 53 is composed of flag portions 53a and 53b, and when the file 1 is closed, the flag portions 53a and 53b are sandwiched between the back cover 22 and the writing paper 23, restricting rotation. Furthermore, when the file 1 is open, the flag portions 53a and 53b are sandwiched between the front cover 21 and the writing paper 23, restricting rotation, except when the flag portions 53a and 53b are exposed at the top. Furthermore, the positions of the inlet / outlet portions 52a and 52b are misaligned, and when the flag portions 53a and 53b are sandwiched between the front cover 21 and the writing paper 23, the inlet / outlet portion 52a is in a position where it is difficult to reach the edge portion 61c of the slot. The presence of the flag portions 53a and 53b prevents the edge portion 61c of the slot from entering the inlet / outlet portion 52b. That is, the binding device 5 according to the first embodiment prevents the edge portion 61c of the slot from entering the inlet / outlet portion 52. If the edge portion 61c of the slot enters the inlet / outlet portion 52, there is a concern that the object 2 to be bound may move in the vertical direction. However, the binding device 5 according to this embodiment restricts the movement of the object 2 to be bound in the vertical direction, and can bind the object 2 to be bound at the appropriate position. Furthermore, since the movement restricting portion 53 is provided at a position eccentric to the central axis of the binding device 5, more pieces of writing paper 23 can be bound compared to when the movement restricting portion 53 is provided on the central axis of the binding device 5.

[0040] Furthermore, in the file 1 according to the first embodiment, the long hole 61 is provided with a long hole protrusion 61a and a long hole recess 61b. By providing the long hole protrusion 61a, it is possible to restrict the movement of the bound body 2 in the left-right direction. Furthermore, by providing the long hole recess 61b, it becomes easier to pass the flag portions 53a, 53b through the long hole 61. In other words, it becomes easier to replace the bound body 2.

[0041] Second Embodiment <Configuration> Next, a file 1 equipped with a binding device 5 according to a second embodiment will be described. The same components as those in the first embodiment will be assigned the same reference numerals and will not be described again. The differences from the first embodiment will be mainly described. Fig. 13 shows a front view of a file equipped with a binding device according to the second embodiment. Fig. 14 shows a side view of the binding device according to the second embodiment (bound state). Fig. 15 shows a side view of the binding device according to the second embodiment (replaced state).

[0042] The file 1 equipped with the binding device 5 according to the second embodiment has a simpler configuration than the file 1 equipped with the binding device 5 according to the first embodiment. Specifically, the long holes 61 of the object 2 to be bound are rectangular in shape and are long in the vertical direction, and have a simple configuration without a convex portion 61a of the long holes or a concave portion 61b of the long holes.

[0043] The binding device 5 has a simple configuration without flag portions 53a and 53b. The binding device 5 includes a support portion 51, a discontinuous portion 54, and an in / out portion 52. In the bound state, the support portion 51 forms a continuous cylindrical shape across the binding device 5 and is inserted into the binding hole 6 of the object 2 to support the object 2 as a continuous region, in other words, a surface. The discontinuous portion 54 is configured as a spirally formed notch. The in / out portion 52 is configured as a gap formed at both ends of the discontinuous portion 54. The in / out portion 52 appears as a gap that can be freely inserted and removed from the elongated hole 61 when the binding device 5 is deformed, for example, when a force is applied in the vertical direction or when a force is applied to pull the ends of the discontinuous portion 54 apart. In the binding device 5 according to the second embodiment, the in / out portion 52 is formed along the notch of the spiral discontinuous portion 54. In other words, the inlet / outlet portion 52 according to the second embodiment is configured with an oblique cut. Inlet / outlet portion 52a (lower side in FIGS. 14 and 15) and inlet / outlet portion 52b (upper side in FIGS. 14 and 15) are provided with offset positions in the outer circumferential direction so that when one is visually recognized as being overlapped with the central axis of the binding device 5 in a side view, the other is visually recognized as being eccentric to the central axis of the binding device 5.

[0044] <How to use> First, the case where the binding device 5 is attached to the file 1 will be described. The binding device 5 is deformed, the inlet / outlet portion 52a of the binding device 5 appears (a gap is created), and the edge portion 61c of the slot in the object 2 is inserted into the inlet / outlet portion 52a. Next, the binding device 5 is rotated clockwise around the central axis. As the binding device 5 rotates, the edge portion 61c of the slot gradually moves upward along the spiral discontinuous portion 54. As the binding device 5 rotates further, the edge portion 61c of the slot fits inside the tubular binding device 5. As a result, the support portion 51 comes into contact with the slot 61 in the object 2, supporting the object 2.

[0045] Next, a description will be given of the case where the binding device 5 is removed from the file 1. First, the binding device 5 is deformed, and the edge portion 61c of the elongated hole is inserted into the in-and-out portion 52b. Next, the binding device 5 is rotated counterclockwise. As the binding device 5 rotates, the binding device 5 gradually comes out of the elongated hole 61. As the binding device 5 continues to rotate, the binding device 5 eventually comes out completely from the elongated hole 61. Note that since the binding device 5 according to the second embodiment does not have the flag portions 53a, 53b, the edge portion 61c of the elongated hole may be inserted through the in-and-out portion 52b, and the above procedure may be carried out.

[0046] <Effects> The file 1 equipped with the binding device 5 according to the second embodiment has a simpler configuration than the first embodiment. Moreover, in the file 1 equipped with the binding device 5 according to the second embodiment, the binding device 5 is made of a deformable resin, and by having a discontinuous portion 54 and an in-and-out portion 52, the bound object 2 can be freely replaced. The binding device 5 according to the second embodiment can be easily removed from either the in-and-out portion 52a or the in-and-out portion 52b. Moreover, since the binding device 5 according to the first embodiment is made of a deformable resin, it puts less pressure on the hand and is easy to write with.

[0047] Furthermore, if the positions of the inlet / outlet portions 52a and 52b were aligned, there would be a concern that the bound object 2 would alternately enter the inlet / outlet portions 52a and 52b, increasing the distance traveled when moving up and down. In the file 1 equipped with the binding device 5 according to the second embodiment, the positions of the inlet / outlet portions 52a and 52b in the outer circumferential direction are misaligned, making it difficult for the bound object 2 to alternately enter the inlet / outlet portions 52a and 52b. As a result, movement of the binding device 5 can be suppressed.

[0048] <Third embodiment> <Configuration> Next, a file 1 equipped with a binding device 5 according to a third embodiment will be described. The same components as those in the previously described embodiment will be assigned the same reference numerals, and a description thereof will be omitted. The following description will focus on differences from the previously described embodiment. Fig. 16 shows a side view (bound state) of the binding device according to the third embodiment. Fig. 17 shows a side view (replaced state) of the binding device according to the third embodiment.

[0049] Although not shown in the figures, the file 1 equipped with the binding device 5 according to the third embodiment is the bound body 2 according to the second embodiment, and the long hole 61 is a rectangle that is long in the vertical direction, and has a simple configuration that does not have a long hole convex portion 61a or a long hole concave portion 61b.

[0050] The binding device 5 differs from the first embodiment in flag portions 53a, 53b, 53c, and 53d. The binding device 5 includes a support portion 51, a discontinuous portion 54, an in / out portion 52, and flag portions 53a, 53b, 53c, and 53d as a movement restricting portion 53. In the bound state, the support portion 51 forms a continuous ring (tube) in the region constituting the binding device 5, and is inserted into the binding hole 6 of the bound object 2 to support the bound object 2 with a continuous region (surface). The discontinuous portion 54 is configured as a notch formed in a spiral shape. The in / out portion 52 is configured as a notch formed at both ends of the discontinuous portion 54. The in / out portion 52 appears as a gap that can be freely inserted into and removed from the binding hole when the binding device is deformed, for example, when a force is applied in the vertical direction or when a force is applied so as to pull apart the ends of the discontinuous portion 54. In the binding device 5 according to the third embodiment, the inlet / outlet portion 52 is configured by a straight incision parallel to the central axis of the binding device 5 at both ends of the incision of the spiral discontinuous portion 54. The inlet / outlet portion 52a (lower side in Figs. 16 and 17) and the inlet / outlet portion 52b (upper side in Figs. 16 and 17) are formed so as to be at the same position in the outer circumferential direction.

[0051] Flag portions 53a, 53b, 53c, and 53d serving as movement restricting portion 53 are provided in the vicinity of entrance / exit portion 52a and entrance / exit portion 52b, and are made up of protrusions that protrude in the axial direction from the end of binding device 5. Each of flag portions 53a, 53b, 53c, and 53d provided in the vicinity of entrance / exit portion 52a and entrance / exit portion 52b has flag portions 53c and 53d provided in the vicinity of entrance / exit portion 52a, and flag portions 53a and 53b provided in the vicinity of entrance / exit portion 52b.

[0052] <How to use> First, we will explain how to attach the binding device 5 to the file 1. The binding device 5 is deformed, and the entrance / exit portion 52a of the binding device 5 appears (a gap is created), and the edge portion 61c of the slot in the object 2 is inserted into the entrance / exit portion 52a. Next, the binding device 5 is rotated clockwise around its central axis. As the binding device 5 rotates, the edge portion 61c of the slot gradually moves upward along the spiral discontinuous portion 54. As the binding device 5 rotates, the flag portions 53c and 53d repeatedly pass through the slot 61. As the binding device 5 further rotates, the edge portion 61c of the slot fits inside the tubular binding device 5. At this time, the flag portions 53a, 53b, 53c, and 53d are positioned between the back cover 22 and the writing paper 23. The support portion 51 contacts the slot 61 in the object 2, supporting the object 2.

[0053] Next, a description will be given of the case where the binding device 5 is removed from the file 1. First, the binding device 5 is deformed, and the edge portion 61c of the elongated hole is inserted into the in-and-out portion 52b. Next, the binding device 5 is rotated counterclockwise. As the binding device 5 rotates, the binding device 5 gradually comes out of the elongated hole 61. As the binding device 5 rotates, the flag portions 53c and 53d repeatedly pass through the elongated hole 61. As the binding device 5 continues to rotate, the binding device 5 eventually comes out of the elongated hole 61 completely. Note that with the binding device 5 according to the third embodiment, the edge portion 61c of the elongated hole may be inserted through the in-and-out portion 52b, and the above procedure may be performed.

[0054] <Effects> In the file 1 equipped with the binding device 5 according to the third embodiment, the binding device 5 is made of a deformable resin, and by having a discontinuous portion 54 and an in / out portion 52, the bound object 2 can be freely replaced. The binding device 5 according to the third embodiment can be easily removed from either the in / out portion 52a or the in / out portion 52b. Furthermore, because the binding device 5 according to the third embodiment is made of a deformable resin, it puts less pressure on the hand and makes writing easier.

[0055] Furthermore, the binding device 5 according to the third embodiment is provided with a movement restricting portion 53, which can restrict movement of the binding device 5. Specifically, in the bound state, the edge portion 61c of the binding hole is prevented from entering the in / out portion 52, thereby allowing the bound object 2 to be bound at an appropriate position. Furthermore, since the edge portion 61c of the elongated hole is unlikely to enter the in / out portion 52, the binding state is not released. Furthermore, in the binding device 5 according to the third embodiment, when the file 1 is closed, the movement restricting portion 53 is sandwiched between the back cover 22 and the writing paper 23, restricting rotation. Furthermore, even when the file 1 is open, the movement restricting portion 53 is sandwiched between the back cover 22 and the writing paper 23, restricting rotation, except when the movement restricting portion 53 is exposed to the top surface. That is, in the binding device 5 according to the first embodiment, the edge portion 61c of the elongated hole is prevented from entering the in / out portion 52. The binding device 5 according to this embodiment can restrict the vertical movement of the bound body 2 and bind the bound body 2 at an appropriate position. The movement restricting portion 53 may be sandwiched between the front cover 21 and the writing paper 23 to restrict rotation.

[0056] <Fourth embodiment> <Configuration> Next, a file 1 equipped with a binding device 5 according to a fourth embodiment will be described. The same components as those in the previously described embodiments will be assigned the same reference numerals, and a description thereof will be omitted. The following description will focus on the differences from the previously described embodiments. Fig. 18 shows a side view (bound state) of the binding device according to the fourth embodiment. Fig. 19 shows a side view (replaced state) of the binding device according to the fourth embodiment. Fig. 20 shows an exploded view of the binding device according to the fourth embodiment. Fig. 21 shows a side view of the binding device according to the fourth embodiment when opened.

[0057] Although not shown in the figures, the file 1 equipped with the binding device 5 according to the fourth embodiment is the bound body 2 according to the second embodiment, and the long hole 61 is a rectangle that is long in the vertical direction, and has a simple configuration that does not have a convex portion 61a of the long hole or a concave portion 61b of the long hole.

[0058] The binding device 5 according to the fourth embodiment has a double-tube structure consisting of an outer portion 56a and an inner portion 56b, and does not have flag portions 53a and 53b. The binding device 5 includes the outer portion 56a and the inner portion 56b, and the outer portion 56a and the inner portion 56b have support portions 51 (51a and 51b), discontinuous portions 54 (54a and 54b), and in-and-out portions 52 (52a, 52b, and 52c). The outer portion 56a and the inner portion 56b are connected at their upper ends. In the bound state, the support portions 51 (51a and 51b) form a double-tube structure in which the areas constituting the binding device 5 are continuous, and the inner portion 56b contacts the binding hole 6 of the object 2 to support the object 2 with a continuous area (surface). The discontinuous portions 54 (54a and 54b) are formed by spirally formed notches. The discontinuous portion 54a of the outer portion 56a and the discontinuous portion 54b of the inner portion 56b are configured as spiral cuts in opposite directions. The in-and-out portions 52 (52a, 52b, 52c) include the in-and-out portion 52a of the outer portion 56a, the in-and-out portion 52c formed at the connection between the outer portion 56a and the inner portion 56b, and the in-and-out portion 52b of the inner portion 56b. The in-and-out portion 52a of the outer portion 56a and the in-and-out portion 52b of the inner portion 56b are configured to be positioned opposite each other, in other words, one in-and-out portion 52 is positioned on the opposite side of the other in-and-out portion 52. The in-and-out portion 52 appears as a gap that can be freely inserted and removed from the binding hole when the binding tool is deformed, for example, when a force is applied in the vertical direction or when a force is applied so as to pull apart the ends of the discontinuous portions 54.

[0059] <How to use> First, the attachment of the binding device 5 to the file 1 will be described. The arrows in FIG. 21 indicate the flow of the edge 61c of the slot. The outer portion 56a and the inner portion 56b overlap, but for clarity, the outer portion 56a and the inner portion 56b are shown separated in FIG. 21. The binding device 5 is deformed, and the inlet / outlet portion 52a of the binding device 5 (the inlet / outlet portion 52a of the outer portion 56a) appears (a gap is created), and the edge 61c of the slot is inserted into the inlet / outlet portion 52a. Next, the binding device 5 is rotated counterclockwise around the central axis. As the binding device 5 rotates, the edge 61c of the slot gradually moves upward along the spiral discontinuous portion 54a formed in the outer portion 56a. The binding device 5 is rotated so that the edge 61c of the slot always enters the inlet / outlet portion 52a of the outer portion 56a. As the binding device 5 further rotates, the edge 61c of the slot reaches the inlet / outlet portion 52c formed at the connection between the outer portion 56a and the inner portion 56b, and then gradually moves downward along the spiral discontinuous portion 54b formed on the inner portion 56b. When the edge 61c of the slot reaches the inlet / outlet portion 52b of the inner portion 56b, the edge 61c of the slot fits inside the binding device 5 with a double-tube structure. As a result, the support portion 51 of the inner portion 56b is inserted into the slot 61 of the object to be bound 2 and faces or contacts its end, thereby supporting the object to be bound 2.

[0060] Next, the removal of the binding device 5 from the file 1 will be described. First, the binding device 5 is deformed, and the edge 61c of the slot is inserted into the in-out portion 52b of the inner portion 56b. Next, the binding device 5 is rotated clockwise. As the binding device 5 rotates, it gradually moves upward along the spiral discontinuous portion 54b formed on the inner portion 56b. As the binding device 5 continues to rotate, the edge 61c of the slot reaches the in-out portion 52c formed at the connection between the outer portion 56a and the inner portion 56b, and then gradually moves downward along the spiral discontinuous portion 54a formed on the outer portion 56a. When the edge 61c of the slot reaches the in-out portion 52a of the outer portion 56a, the binding device 5 is released from the slot 61.

[0061] <Effects> In the file 1 equipped with the binding device 5 according to the fourth embodiment, the binding device 5 is made of a deformable resin, and by having discontinuous portions 54 (54a, 54b) and in-and-out portions 52 (52a, 52b, 52c), the bound object 2 can be freely replaced. Furthermore, in the file 1 equipped with the binding device 5 according to the fourth embodiment, the binding device 5 has a double-tube structure, so it can bind the bound object 2 more stably. Furthermore, since the binding device 5 according to the first embodiment is made of a deformable resin, it puts less pressure on the hand and is easy to write in.

[0062] Furthermore, in the file 1 equipped with the binding device 5 according to the fourth embodiment, the positions of the in-and-out portions 52a and 52b in the outer circumferential direction are misaligned, making it difficult for the binding device 5 to simultaneously enter the in-and-out portions 52a and 52b. As a result, movement of the binding device 5 can be restricted.

[0063] Fifth Embodiment Next, a file 1 equipped with a binding device 5 according to a fifth embodiment will be described. The same components as those in the previously described embodiments will be assigned the same reference numerals, and a description thereof will be omitted. The following description will focus on differences from the previously described embodiments. Figure 22 shows a perspective view (bound state) of the binding device according to the fifth embodiment. Figure 23 shows a perspective view (replaced state) of the binding device according to the fifth embodiment.

[0064] Although not shown in the figures, the file 1 equipped with the binding device 5 according to the fifth embodiment is the bound body 2 according to the second embodiment, and the long hole 61 is a rectangle that is long in the vertical direction, and has a simple configuration that does not have a convex portion 61a of the long hole or a concave portion 61b of the long hole.

[0065] The binding device 5 includes a support portion 51, a discontinuous portion 54, an in / out portion 52, and a movement restricting portion 53. In the binding state, the support portion 51 forms a continuous cylindrical shape in the region constituting the binding device 5, and contacts the long hole 61 of the object to be bound 2 to support the object to be bound 2 with a continuous region (surface). The discontinuous portion 54 is configured as a cut formed in a straight line parallel to the central axis of the binding device 5. In this embodiment, the discontinuous portion 54 becomes the in / out portion 52. That is, the in / out portion 52 appears as a linear gap that can be freely inserted and removed from the long hole 61 when the binding device is deformed and a force is applied that widens the discontinuous portion 54.

[0066] The movement restricting portion 53 is provided along the inlet / outlet portion 52, in other words, the discontinuous portion 54, and is composed of two opposing rectangular pieces 53e and 53f that protrude outward from the surface of the binding device 5.

[0067] <How to use> First, the case where the binding device 5 is attached to the file 1 will be described. The binding device 5 is deformed; specifically, the discontinuous portion 54 is widened, the entrance / exit portion 52 of the binding device 5 appears (a gap is created), and the edge portion 61c of the elongated hole in the object to be bound 2 is inserted into the entrance / exit portion 52. As a result, the edge portion 61c of the elongated hole fits inside the tubular binding device 5. At this time, the movement restricting portion 53 is positioned between the front cover 21 and the writing paper 23. The object to be bound 2 is supported by the support portion 51 being inserted into the elongated hole 61 of the object to be bound 2 and facing or contacting its end portion.

[0068] Next, we will explain how to remove the binding device 5 from the file 1. The binding device 5 is deformed, specifically, the discontinuous portion 54 is widened, the entrance / exit portion 52 of the binding device 5 appears (a gap is created), and the edge portion 61c of the long hole of the object 2 to be bound comes off from the entrance / exit portion 52.

In the binding device 5 according to the fifth embodiment, the bound object 2 can be replaced simply by widening the discontinuous portion 54. Furthermore, in the binding device 5 according to the fifth embodiment, the support portion 51 that supports the bound object 2 is made of a deformable resin, which reduces pressure on the hand and makes writing easier. Furthermore, the binding device 5 according to the fifth embodiment is equipped with pieces 53e and 53f as the movement restriction portion 53, which makes it possible to restrict the movement of the binding device 5.

[0070] Sixth Embodiment Next, a file 1 equipped with a binding device 5 according to a sixth embodiment will be described. The same components as those in the previously described embodiments will be assigned the same reference numerals, and a description thereof will be omitted. The following description will focus on differences from the previously described embodiments. Figure 24 shows a perspective view of the binding device according to the sixth embodiment (in a bound state). Figure 25 shows a perspective view of the binding device according to the sixth embodiment (in a replaced state).

[0071] Although not shown in the figures, the file 1 equipped with the binding device 5 according to the sixth embodiment is the bound body 2 according to the second embodiment, and the long hole 61 is a rectangle that is long in the vertical direction, and has a simple configuration that does not have a convex portion 61a of the long hole or a concave portion 61b of the long hole.

[0072] The binding device 5 includes a support portion 51, a discontinuous portion 54, an in / out portion 52, and a movement restricting portion 53. In the binding state, the support portion 51 forms a continuous cylindrical shape in the region constituting the binding device 5, and contacts the long hole 61 of the object to be bound 2 to support the object to be bound 2 with a continuous region (surface). The discontinuous portion 54 is configured as a cut formed in a straight line parallel to the central axis of the binding device 5. In this embodiment, the discontinuous portion 54 becomes the in / out portion 52. That is, the in / out portion 52 appears as a linear gap that can be freely inserted and removed from the long hole 61 when the binding device is deformed, specifically, when a force is applied that widens the discontinuous portion 54.

[0073] The movement restricting portion 53 is provided along the inlet / outlet portion 52, in other words, the discontinuous portion 54, and is composed of two rectangular pieces 53g and 53h that protrude outward from the surface of the binding device 5. In the sixth embodiment, unlike the fifth embodiment, the two pieces 53g and 53h do not face each other (do not overlap), but are provided alternately.

[0074] <How to use> First, the case where the binding device 5 is attached to the file 1 will be described. The binding device 5 is deformed; specifically, the discontinuous portion 54 is widened, the entrance / exit portion 52 of the binding device 5 appears (a gap is created), and the edge portion 61c of the elongated hole in the object to be bound 2 is inserted into the entrance / exit portion 52. As a result, the edge portion 61c of the elongated hole fits inside the tubular binding device 5. At this time, the movement restricting portion 53 is positioned between the front cover 21 and the writing paper 23. The object to be bound 2 is supported by the support portion 51 being inserted into the elongated hole 61 of the object to be bound 2 and facing or contacting its end portion.

[0075] Next, we will explain how to remove the binding device 5 from the file 1. The binding device 5 is deformed, specifically, the discontinuous portion 54 is widened, the entrance / exit portion 52 of the binding device 5 appears (a gap is created), and the edge portion 61c of the long hole of the object 2 to be bound comes off from the entrance / exit portion 52.

The binding device 5 according to the sixth embodiment allows the binding object 2 to be replaced simply by widening the discontinuous portion 54. Furthermore, since the binding device 5 according to the sixth embodiment is made of a deformable resin, it puts less pressure on the hand and makes writing easier. Furthermore, the binding device 5 according to the sixth embodiment includes two pieces 53g, 53h as the movement restricting portion 53, which can restrict the movement of the binding device 5. Furthermore, the two pieces 53g, 53h as the movement restricting portion 53 according to the sixth embodiment are arranged alternately so as not to overlap, and therefore the discontinuous portion 54 can be easily widened by pinching the two pieces 53g, 53h.

[0077] Seventh Embodiment <Configuration> Next, a file 1 equipped with a binding device 5 according to a seventh embodiment will be described. The same components as those in the previously described embodiments will be assigned the same reference numerals, and a description thereof will be omitted. The following description will focus on differences from the previously described embodiments. Figure 26 shows a side view (bound state) of the binding device according to the seventh embodiment. Figure 27 shows a side view (replaced state) of the binding device according to the seventh embodiment.

[0078] Although not shown in the figures, the file 1 equipped with the binding device 5 according to the seventh embodiment is the bound body 2 according to the second embodiment, and the long hole 61 is a rectangle that is long in the vertical direction, and has a simple configuration that does not have a long hole convex portion 61a or a long hole concave portion 61b.

[0079] The binding device 5 includes a support portion 51, a discontinuous portion 54, an in / out portion 52, and engagement portions 55 (55a, 55b). In the bound state, the support portion 51 forms a continuous cylindrical shape in the region constituting the binding device 5, and contacts the binding hole 6 of the object to be bound 2 to support the object to be bound 2 with a continuous region (surface). The discontinuous portion 54 is configured as a cut formed in a straight line parallel to the central axis of the binding device 5. In this embodiment, the discontinuous portion 54 becomes the in / out portion 52. That is, the in / out portion 52 appears as a linear gap that can be freely inserted and removed from the elongated hole 61 when the binding device 5 is deformed, specifically, when a force is applied to widen the discontinuous portion 54. In the binding device 5, the discontinuous portion 54 is formed thicker than other regions, and the engagement portions 55 (55a, 55b) are provided at the discontinuous portion 54. The engaging portion 55 (55a, 55b) includes a protruding engaging convex portion 55a and an engaging concave portion 55b that is recessed to engage with the engaging convex portion 55a.

[0080] <How to use> First, we will explain how to attach the binding device 5 to the file 1. The binding device 5 is deformed, specifically, the discontinuous portion 54 is widened, the in-and-out portion 52 of the binding device 5 appears (a gap is created), and the edge portion 61c of the long hole of the object 2 is inserted into the in-and-out portion 52. The engaging portions 55 (55a, 55b) are engaged, and the edge portion 61c of the long hole fits inside the tubular binding device 5.

[0081] Next, a description will be given of the case where the binding device 5 is removed from the file 1. The binding device 5 is deformed, specifically, the discontinuous portion 54 is widened, the engagement portions 55 (55a, 55b) are disengaged, the entrance / exit portion 52 of the binding device 5 appears (a gap is created), and the edge portion 61c of the elongated hole of the object 2 to be bound comes off from the entrance / exit portion 52.

The binding device 5 according to the seventh embodiment allows the bound object 2 to be replaced simply by widening the discontinuous portion 54. Furthermore, by providing the engaging portions 55 (55a, 55b), the bound state can be stably maintained. Furthermore, in the binding device 5 according to the seventh embodiment, the support portion 51 that supports the bound object 2 is made of a deformable resin, so it puts less pressure on the hand and makes writing easier.

[0083] Eighth Embodiment <Configuration> Next, a file 1 equipped with a binding device 5 according to an eighth embodiment will be described. The same components as those in the previously described embodiment will be assigned the same reference numerals, and a description thereof will be omitted. The following description will focus on differences from the previously described embodiment. Figure 28 shows a perspective view of the binding device according to the eighth embodiment (in a bound state). Figure 29 shows a perspective view of the binding device according to the eighth embodiment (in a replaced state).

[0084] Although not shown in the figures, the file 1 equipped with the binding device 5 of the eighth embodiment is the bound body 2 of the second embodiment, and the long hole 61 is a rectangle that is long in the vertical direction, and has a simple configuration that does not have a long hole convex portion 61a or a long hole concave portion 61b.

[0085] The binding device 5 according to the eighth embodiment has a double-tube structure made up of an outer portion 56a and an inner portion 56b. The binding device 5 includes the outer portion 56a and the inner portion 56b, and the outer portion 56a and the inner portion 56b have support portions 51 (51a, 51b), discontinuous portions 54 (54a, 54b), and in-and-out portions 52 (52a, 52b). Unlike the fourth embodiment, in the eighth embodiment, the outer portion 56a and the inner portion 56b are made up of separate members. In the binding state, the support portions 51 (51a, 51b) have a continuous double-tube structure in the region that constitutes the binding device 5, and the inner portion 56b contacts the elongated hole 61 of the object 2 to support the object 2 in a continuous region (surface). The discontinuous portions 54 (54a, 54b) are provided in each of the outer portion 56a and the inner portion 56b, and are configured as linearly formed cutouts parallel to the central axis of the binding device 5. In this embodiment, the discontinuous portions 54 (54a, 54b) become the in-and-out portions 52 (52a, 52b). That is, the in-and-out portions 52 (52a, 52b) appear as linear gaps that can be freely inserted and removed from the elongated holes 61 when the binding device 5 is deformed, specifically, when a force is applied that widens the discontinuous portions 54 (54a, 54b). The discontinuous portion 54a of the outer portion 56a and the discontinuous portion 54b of the inner portion 56b are arranged so as not to overlap. In this embodiment, the discontinuous portion 54a of the outer portion 56a is arranged so as to be located opposite the discontinuous portion 54b of the inner portion 56b.

[0086] <How to use> First, the case where the binding device 5 is attached to the file 1 will be described. The binding device 5 is deformed; specifically, the discontinuous portion 54b of the inner portion 56b is widened, the inlet / outlet portion 52b of the binding device 5 appears (a gap is created), and the edge portion 61c of the elongated hole in the object to be bound 2 is inserted into the inlet / outlet portion 52b of the inner portion 56b. Next, the discontinuous portion 54a of the outer portion 56a is widened, the inlet / outlet portion 52a of the binding device 5 appears (a gap is created), and the edge portion 61c of the elongated hole in the object to be bound 2 is inserted into the inlet / outlet portion 52a of the outer portion 56a. As a result, the edge portion 61c of the elongated hole in the object to be bound 2 fits inside the binding device 5 with a double-tube structure. The position is adjusted so that the discontinuous portion 54a of the outer portion 56a is positioned opposite the discontinuous portion 54b of the inner portion 56b.

[0087] Next, a case where the binding device 5 is removed from the file 1 will be described. The binding device 5 is deformed, specifically, the discontinuous portion 54a of the outer portion 56a is widened, and the edge portion 61c of the elongated hole in the object to be bound 2 is released from the in-and-out portion 52a of the outer portion 56a. Next, the discontinuous portion 54b of the inner portion 56b is widened, and the edge portion 61c of the elongated hole in the object to be bound 2 is released from the in-and-out portion 52b of the inner portion 56b.

[0088] <Effects> In the file 1 equipped with the binding device 5 according to the eighth embodiment, the binding device 5 is made of a deformable resin, and includes discontinuous portions 54 (54a, 54b) and in-and-out portions 52 (52a, 52b), allowing the bound body 2 to be freely replaced. The binding device 5 according to the eighth embodiment allows the bound body 2 to be replaced simply by widening the discontinuous portions 54 of the outer portion 56a and the inner portion 56b. Furthermore, since the binding device 5 has a double-tube structure, the bound body 2 can be bound more stably. Furthermore, since the discontinuous portion 54a of the outer portion 56a is positioned opposite the discontinuous portion 54b of the inner portion 56b, the binding device 5 is less likely to come off. Furthermore, since the binding device 5 according to the eighth embodiment is made of a deformable resin, it puts less pressure on the hand and is easy to write on.

[0089] Although the embodiments of the present invention have been described above, the above-described embodiments and other embodiments can be modified as appropriate without departing from the spirit of the present invention. Furthermore, the above-described embodiments may be combined as much as possible. [Explanation of symbols]
