The present invention relates to a binding device to be held.

[0002]

2. Description of the Related Art FIG. 25 is an illustrative view showing a file using a conventional binding device as a background of the present invention. FIG.
FIG. 26 is a front view of a conventional binding device used for the file shown in FIG. 25. FIG. 27 is an illustrative view showing a state of assembling the file shown in FIG. This file includes the binding device 1. The binding device 1 includes a pair of holding members 2a and 2b for holding an object to be held such as a sheet. The pair of holding members 2a and 2b are arranged to face each other in the thickness direction. One end of the pair of sandwiching members 2a and 2b in the width direction is a connecting member 3
Are connected together. A pair of holding members 2a, 2b
The connection member 3 is integrally formed of an elastic and flexible material such as plastic or metal.
At the other end in the width direction of the pair of holding members 2a and 2b, an insertion portion 4 for inserting an object to be held is formed.
In the insertion portion 4, the edges of the pair of holding members 2a and 2b are opposed to each other. When the object to be clamped is inserted from the insertion portion 4 into the pair of clamping members 2a, 2b, the distance between the pair of clamping members 2a, 2b is expanded. Then, a restoring force is applied to the pair of holding members 2a and 2b so as to return to the original state, and the object to be held becomes the pair of holding members 2a and 2b.
2b sandwiches both sides in the thickness direction. A pivoting portion 5 is formed at one longitudinal end of one of the holding members 2b. As shown in FIGS. 26 and 27, the pivot portion 5 is rotatably pivotally attached to a file cover 7 described later by an eyelet 5a.

As shown in FIG. 26, one holding member 2a
The insertion portion 4 is provided at the corner 2c on the side of the pivot portion 5 at the other end in the width direction.
A guide portion 6 is formed so as to be continuous with the insertion portion 4 so as to easily introduce an object to be clamped. This corner portion 2c is a portion that first overlaps with the file cover 7 when the binding tool 1 pivotally attached to the file cover 7 is rotated, as shown by a two-dot broken line in FIG. When there is no guide portion 6, when the binding tool 1 is rotated, a pair of holding members 2a,
It is difficult to introduce an object between 2b. Therefore, the guide portion 6 is formed at the corner 2c.

As shown in FIG. 26, the distance between the guide portion 6 and the other holding member 2b facing in the thickness direction is larger than the distance between the pair of holding members 2a and 2b in the insertion portion 4. It is formed as follows. Thus, the guide part 6
Is formed so as to have a large space between the holding member 2b and the other holding member 2b. Then, by successively rotating the binding tool 1 and inserting the held object from the insertion portion 4 between the pair of holding members 2a, 2b, the pair of holding members 2a, 2b can be easily formed.
An object to be clamped can be inserted between b.

On the other hand, the conventional file cover 7 includes a first main surface member 7a and a second main surface member 7b as shown in FIG. First main surface member 7a and second main surface member 7b
Are integrally formed via the hinge portion 8a. Further, as shown in FIG. 27, a strip-shaped holding piece 7c is formed integrally with the first main surface member 7a via another hinge portion 8b at the center of the file cover 7. The holding piece 7c is
This is for holding an object to be held such as paper between the first main surface member 7a which is bent at the hinge portion 8b and is opposed to the first main surface member 7a. The above-described binding device 1 is pivotally attached to the first main surface member 7a at the pivot portion 5 by, for example, eyelets 5a. In the conventional file cover 7,
FIG. 2 shows a passage for holding an object to be held by the binding device 1.
As shown in FIG. 7, a flat rectangular binding passage 9 is formed. The binding device 1 is rotated as shown by a two-dot chain line in FIG. 25, and passes through the binding device passage 9 to integrally hold the first main surface member 7a, the holding pieces 7c, and the paper held therebetween. .
Further, by rotating the binding device 1 in the opposite direction to that described above, it is possible to release the holding of the held object.

[0006]

However, in the conventional binding device 1 described above, since the guide portion 6 is fixedly provided, even after the object to be clamped is clamped between the pair of clamping members 2a and 2b. The guide portion 6 remains unnecessarily protruding in the thickness direction. Therefore, it is difficult to stack files using the binding device in the thickness direction, and the guide portion is likely to be caught or bumped during use. Also, the appearance is poor.

SUMMARY OF THE INVENTION Therefore, a main object of the present invention is to provide a binding device which is less likely to be caught or hit by a guide portion and which has a good appearance.

[0008]

A binding device according to the present invention comprises a pair of holding members for holding an object to be held, such as paper, and an insertion portion for inserting the object to be held between the pair of holding members. And a connecting portion formed on a side of the pair of holding members facing the insertion portion, for connecting the pair of holding members integrally,
A pivot portion for rotatably pivoting the pair of clamping members to the file cover, and an object to be clamped is first inserted into the insertion portion when the pair of clamping members are pivoted about the pivot portion. And a guide member provided on the coming part and facilitating introduction of the object to be inserted into the insertion portion, wherein the guide member is swingably engaged with the holding member. It is a binding tool. In the binding device of the present invention, the object to be clamped is introduced into the insertion portion according to the guidance of the guide member, and the object to be clamped is inserted between the pair of clamping members to be clamped. Then, the guide member swings, and does not protrude along the surface of the held object as before. As a result, when this binding tool is used, the guide portion is less likely to be caught or hit when using the file. Also, it looks better.

Further, in the binding device according to the present invention, the guide member has, on one main surface, an engaging portion which is engaged with one of the holding members and serves as a fulcrum of swinging, and the other main surface has the other principal surface. The distance between the substrate, which is arranged to face the holding member and is formed to be in contact with the surface of the held object inserted into the insertion portion, and the other opposing holding member is between a pair of holding members in the insertion portion. The guide piece is formed to extend from one end of the board so as to be wider than the gap, and a guide piece for facilitating the introduction of the object to be inserted into the insertion portion, and is formed on the opposite side of the guide piece of the board, and the engaging portion is a fulcrum It is preferable to include a weight for making the opposite side of the substrate heavier than one side of the guide. In this case, before inserting the held object between the pair of holding members,
The weight portion side of the guide member fixed to the holding member hangs downward with the fixed portion as a fulcrum. Therefore, when the pair of holding members are placed substantially horizontally, the guide member is in a state in which one side of the guide extends obliquely upward with respect to the horizontal plane and jumps up. Then, the space between the guide piece and the opposing holding member becomes wider, and the object to be held can be easily inserted from the insertion portion between the pair of holding members. When inserting the object to be clamped between the pair of clamping members, the object to be clamped can be introduced into the insertion portion along the surface of the guide piece facing the clamping member. Since the guide member is swingably engaged with the holding member, when the held object is inserted between the pair of holding members, the weight portion is pushed up by the thickness of the held object. As a result, the guide member swings around the engagement portion, and the substrate becomes substantially parallel along the main surface of the held object,
The direction in which the guide pieces extend also approaches the horizontal direction. That is,
The guide member can be simultaneously swung simply by inserting the object to be held between the pair of holding members. Then, the main surface of the held object comes into contact with the other main surface of the substrate of the guide member.
Therefore, the held object is also held between the holding member facing the substrate of the guide member. Then, when the object to be clamped is taken out from the binding device, there is no longer anything to push up the guide member, so the guide member swings in the opposite direction to the above,
The weight part hangs down, and the guide piece returns to a state in which the guide piece jumps up diagonally upward.

Further, in the binding device according to the present invention, the substrate of the guide member is disposed between the pair of holding members, is swingably engaged with one of the holding members, and faces the weight portion of the holding member. It is preferable that a recess for accommodating the weight is formed at the position. In this case, when the object to be clamped is inserted between the pair of clamping members, the substrate of the guide member and the clamped object are integrally clamped by the pair of clamping members, and the clamping member facing the substrate of the guide member and Is more firmly gripped by the object. In addition, since a concave portion for accommodating the weight portion is formed at a position facing the weight portion of the holding member,
Even when the substrate of the guide member swings, the weight portion does not hit the holding member. For this reason, after the guide member has clamped the object to be clamped, the guide member easily follows the main surface of the object to be clamped, and the above-described operation is easily obtained.

Further, in the binding device according to the present invention, an engagement receiving portion for swingably engaging the engagement portion is formed at a position of the one holding member facing the engagement portion, and the other is provided. In a position of the holding member facing the substrate, a through hole serving as a passage for pressing the internal substrate from the outside of the holding member toward one of the holding members and fitting the engagement portion to the engagement receiving portion is provided. Preferably, a hole is formed. When manufacturing the binding tool according to the present invention, a pair of holding members and a guide member are separately prepared. The guide member is inserted between the pair of holding members. Then, the engaging portion of the guide member is fitted to the engaging receiving portion of the holding member by pressing the inner guide member toward the opposing holding member from the outside of the holding member through the through hole. If the other holding member does not have a through hole, this operation is difficult to perform. However, by forming the through hole as described above, the operation of engaging the guide member with the holding member becomes easy, and Manufacturing becomes easier.

Further, in the binding device according to the present invention, a protruding piece for preventing one of the holding members from coming out of the pair of holding members is provided on one holding member toward the other holding member opposed in the thickness direction. The protrusion may be formed. By forming the projecting piece in this manner, when the object to be clamped is sandwiched between the pair of clamping members, the projecting piece comes into a state of protruding from the object to be clamped, and the object to be clamped from the binding tool is freely. It becomes difficult to escape. In addition, by engaging the projecting piece with the file cover, careless rotation of the pair of holding members is prevented.

The above and other objects, features and advantages of the present invention will become more apparent from the following detailed description of embodiments of the present invention with reference to the accompanying drawings.

[0014]

The binding device 10 includes a binding body 12 for clamping an object to be clamped and a binding body 1 for clamping the object to be clamped.
And a guide member 14 for guiding to the second member. The guide member 14 is arranged at a corner 12 a of the binding device main body 12 on the side of the pivot portion.

First, the binding device main body 12 will be described with reference to FIGS. The binding body 12 includes a pair of holding members 16 for holding an object to be held such as paper.
a, 16b. The pair of holding members 16a, 16b
Each is formed in the shape of a strip, and is arranged to face each other in the thickness direction. At one end in the longitudinal direction of the holding member 16a, for example, a rib 18a extending in the longitudinal direction of the holding member is formed so as to protrude from the surface as shown in FIGS. The corner 12a at the other end in the longitudinal direction and the other end in the width direction of the holding member 16a is cut into a triangular shape in order to arrange a guide piece 48 described later. A concave portion 18b is provided at a position corresponding to the rib 18a at one end in the longitudinal direction of the holding member 16b.
Is formed. The ribs 18a and the concave portions 18b prevent the fingertips from slipping when the user rotates the binding device 10. Note that the shapes of the ribs 18a and the concave portions 18b are not limited to this.

One end of the pair of holding members 16a and 16b in the width direction is integrally connected by an elongated rectangular piece-like connecting member 20. As shown in FIGS. 6 and 8, the connection member 20 is formed to extend substantially perpendicular to the main surface of the holding member 16b. The pair of holding members 16a and 16b and the connecting member 20 are integrally formed of a material having elasticity and flexibility, such as plastic or metal.
In the embodiment, for example, it is formed of POM. The other end in the width direction of one holding member 16a extends so as to approach the other end in the width direction of the other holding member 16b as shown in FIGS. Moreover, one of the holding members 16a is
It is formed by a gentle curve with a bow in the width direction. Therefore, as is clear from FIGS. 6 and 8, the cross-sectional shape of the binding tool main body 12 is formed in a substantially triangular shape. Hereinafter, the holding member 16a side will be referred to as the front side of the binding device 10, and the holding member 16b side will be referred to as the back surface side of the binding device 10.

At the other end in the width direction of the pair of holding members 16a, 16b, as shown in FIGS. 6 and 8, an insertion portion 22 for inserting a held object is formed. This insertion part 2
Reference numeral 2 denotes a pair of edges of the pair of holding members 16a and 16b facing each other. When the object to be clamped is inserted from the insertion portion 22 into the pair of clamping members 16a, 16b, the interval between the pair of clamping members 16a, 16b is expanded.
Then, a restoring force is applied to the pair of holding members 16a and 16b to return to the original state, and the object to be held is held from both sides in the thickness direction by the edges of the pair of holding members 16a and 16b. In addition, in the binding device 10, for example, three protruding pieces 23a are formed on the periphery of one holding member 16a as shown in FIGS. Is done. The protruding pieces 23a are formed so as to protrude toward the edge of the other holding member 16b. In addition, a concave portion 23b for accommodating the distal end portion of the protruding piece 23a is formed at an edge of the other holding member 16b facing the protruding piece 23a. When the object to be clamped is clamped by the binding body 12, the projecting piece 23a is urged toward the recess 23b by the restoring force of the pair of clamping members 16a, 16b, so that the tip of the projecting piece 23a is clamped. It protrudes from the surface of the object and tries to fit into the recess 23b. Therefore, the object to be held is reliably held so as to be bitten between the projecting piece 23a and the concave part 23b. Therefore,
It is difficult for the held object held by the binding device 10 to come out of the space between the pair of holding members 16a and 16b.

The holding member 16 on the back side of the binding device 10
A pivot piece 24 is integrally formed at one end in the longitudinal direction of b. The pivot piece 24 is formed so as to extend outward from one end in the longitudinal direction of the holding member 16b. And
A pivot hole 26 as a pivot portion is formed in the pivot piece 24 in the thickness direction. The pivot hole 26 is a hole for attaching an eyelet to a file cover described later. As shown in FIGS. 4 and 8, an eyelet receiving portion 28 for accommodating a head portion of an eyelet, which will be described later, is formed on the back side of the pivotal piece 24, as shown in FIGS. 4 and 8. I have.

Furthermore, the holding member 1 on the front side of the binding device 10
In the vicinity of one end in the longitudinal direction of 6a, as shown in FIG.
An oblong attachment hole 30 extending obliquely is formed penetrating the holding member 16a in the thickness direction. An engagement receiving portion 32 is formed in the engagement hole 30 for swingably supporting a guide member described later. The engagement receiving portion 32 of the binding device 10 is shown in FIG.
As shown in FIG.
It is formed so as to protrude inward from the contour of 0. The engagement receiving portion 32 is formed corresponding to an engagement portion 46 of the guide member described later. As is apparent from FIG. 3, the engagement receiving portions 32 are not formed at both ends in the length direction of the engagement hole 30. The cross-sectional shape of the engagement receiving portion 32 is shown in FIG.
As shown in the figure, in the thickness direction of the holding member 16a, the length of the holding member 16a protruding inside the hole increases toward the other holding member 16b. In addition, the surface of the engagement receiving portion 32 exposed on the front surface side of the binding tool 10 is formed to have a curved surface shape that wraps the circular body from below. As shown in FIG. 2, this is for swingably supporting the substantially arc-shaped surface of the engaging portion 46 of the guide member 14 described below so as to be received from below.

The holding member 16 on the front side of the binding device 10
As shown in FIG. 3, the holding member 1 has an elongated weight storage hole 34 extending obliquely in parallel with the above-described engagement hole 30.
6a in the thickness direction. Weight storage hole 34
As shown in FIGS. 23 and 24, is a recess for accommodating a later-described weight portion so as not to hinder swinging of a later-described guide member. Therefore, the weight portion storage hole 34 is formed at a position facing the second protrusion 50 as a weight portion of the guide member described later. Furthermore, binding device 1
As shown in FIGS. 2, 4 and 5, a through hole 36 penetrates through the holding member 16b in the thickness direction at a position facing the engaging hole 30 on the front side, as shown in FIGS. Formed. As shown in FIG. 13, the through-holes 36 are provided so that the guide member 14 from the outside to the inside of the binding tool main body 12 can be easily engaged with the fastening holes 30 when the binding tool 10 is manufactured. It becomes a passage for pushing up.

Next, the guide member 14 of the binding device 10 will be described with reference to FIGS. The guide member 14 is for facilitating introduction of the object to be inserted into the insertion section 22 described above. Guide member 14
Includes a planar trapezoidal substrate 40 as shown in FIG. A first projection 42 is formed on one main surface of the substrate 40.
The first protrusion 42 is formed so as to protrude from one main surface of the substrate 40, as shown in FIG. As shown in FIG. 12, a substrate 40 is provided on both sides of the center of the first projection 42, respectively.
Rectangular hole-shaped engaging portion forming hole 44 penetrating in the thickness direction of
Is formed. Further, the first connecting portion 44 connected to the engaging portion forming hole 44 is formed.
The surface of the projection 42 is formed to have a curved surface having a substantially arc-shaped cross section as shown in FIG. Therefore, the first projection 42
A concave portion having a curved surface is formed on both sides of the central portion of the central portion, and the concave portion functions as an engaging portion 46 for engaging the protruding portion of the engaging receiving portion 32. In other words, as shown in FIGS. 10 and 12, the constricted portion at the center of the first projection 42 becomes the engaging portion 46. Then, the engaging portion 46
Is supported by the engagement receiving portion 32 of the holding member 16a while having play so that the substrate 40 can swing. The other main surface of the substrate 40 functions as a pressing surface 40a for pressing the main surface of an object to be held such as paper.

As shown in FIG. 10, a guide piece 48 having, for example, a plane triangular shape is formed integrally with one end of the substrate 40. When the guide member 14 is engaged with the holding member 16a, the guide piece 48 complements the cut off portion of the holding member 16a, and the guide piece 48 and the holding member 1
6a are formed in such a size and shape that a strip shape is completed when viewed together. When viewed from the front, the guide piece 48 is formed in a bowed manner as shown in FIG. Then, the other main surface side of the guide piece 48 functions as a guide surface 48a for abutting and guiding the held object.

On one main surface of the other end of the substrate 40, FIG.
As shown in FIG. 5, a second projection 50 as a weight portion is formed in parallel with the first projection 42. The outer shape of the second projection 50 is formed in substantially the same shape as the first projection 42. However, the second projection 50 is larger in volume and heavier than the first projection 42 because the engagement portion forming hole 44 and the engagement portion 46 are not formed. Therefore, the guide member 1
4 is engaged with the holding member 16a, the other end of the substrate 40 is heavier than the one end. Therefore, the guide member 1
When the binding device main body 12 is placed horizontally after swingably engaging the holding member 4 with the holding member 16a, the guide member 14 swings in the direction indicated by the solid arrow in FIG. I do. As a result, as is clear from FIG.
The distance between the holding member 16b and the opposed holding member 16b increases.
Therefore, it is easy to introduce the object to be held between the pair of holding members 16a and 16b along the guide surface 48a. When the object to be clamped is inserted between the pair of clamping members 16a and 16b, the main surface of the object to be clamped becomes the pressing surface 4 on the back surface of the substrate 40.
0a, and pushes up the substrate 40 in the direction of the holding member 16a. Then, as shown by a chain line in FIG.
Swings and becomes substantially parallel along the main surface of the held object. Then, the held object is held between the holding surface 40a on the back surface of the substrate 40 and the holding member 16b facing the holding member.

Next, a method of engaging the guide member 14 with the binding device main body 12 will be described with reference to FIG. The guide member 14 is provided at the corner 12a of the binding device main body 12 shown in FIG.
Placed in The substrate 40 is arranged between the pair of holding members 16a and 16b as shown in FIG. Guide piece 4
8 extends outward from between the pair of holding members 16a and 16b. Then, the position of the guide member 14 is adjusted such that the first projection 42 faces the engagement hole 30 and the second projection 50 faces the weight portion storage hole 34. Then, the pressing rod S is inserted into the through hole 36 and the substrate 4 of the guide member 14 is
0 is pushed up in the direction of the holding member 16a. Nipping member 16a
Is formed of a material having elasticity and flexibility as described above, so that the first projections 42 are inserted into the engagement holes 30 while pushing between the narrow engagement receiving portions 32. Is done. At the same time, the second protrusion 50 is housed in the weight housing hole 34. The guide member 14 is shown by a two-dot chain line in FIG. 13 by fitting the engagement receiving portion 32 projecting in the center direction of the engagement hole 30 into the engagement portion 46 at the center of the first projection 42. In this way, it is engaged with the binding device main body 12. The guide member 14 includes an engagement portion 46 supported by the engagement receiving portion 32.
Can be swung around the fulcrum.

Next, a file cover to which the above-described binding device 10 is attached will be described with reference to FIG. The file cover 60 shown in FIG. 14 includes, for example, a rectangular base sheet 62. The base sheet 62 is made of, for example, a synthetic resin material such as polypropylene, polyethylene, or polyvinyl chloride. In the embodiment, the transparent or translucent polypropylene is used. The base sheet 62 includes main surface members 64a and 64b. The main surface member 64a and the main surface member 64b are integrally formed via a hinge 66 at the center of the base sheet 62. The hinge portion 66 is composed of two parallel fold lines at a predetermined interval from each other. The hinge portion 66 is connected to the base sheet 62.
Is punched out from a raw material in the form of a plate or a roll, and is simultaneously formed by press working. The hinge portion 66 is not limited to forming two fold lines, but may be formed in other numbers. For example, when forming three fold lines,
In order to make the main surface members 64a, 64b easy to turn back,
The middle one of the three fold lines may be formed by pressing more strongly than the two fold lines.

At the center of the base sheet 62, the main surface member 6
A binding passage 68 to be a passage of the binding device 10 is formed by penetrating the binding device 4b in the thickness direction. This binding device passage 68
For example, it is formed in a flat rectangular shape slightly larger than the outer shape of the binding device 10. A substantially triangular end passage 70 is formed at the upper end of the binding passage 68 to serve as a passage at the end of the binding device 10 on the guide member 14 side. Therefore, when the binding member passage 68 and the end portion passage 70 are viewed integrally, a trapezoidal through hole is formed as shown in FIG.
The end passage 70 connects the main surface members 64b and 64a in FIG.
To the binding device 10 in the unfolded state as shown in FIG.
When the is rotated as shown in FIG. 20, the corner 12b facing the guide member 14 of the binding device 10 in the width direction is prevented from hitting the main surface member 64b to prevent the main surface member 64b from being damaged. It is for doing. Note that the shape of the end passage 70 is not limited to that of this embodiment.
For example, as shown in FIG. 15, the end passage 70 may be formed in a substantially rectangular shape only on the main surface member 64a side in the width direction at the upper end of the binding device passage 68.

In the binding member passage 68, a strip-shaped holding piece 72 for holding a central portion at one end side in the width direction of an object to be held such as a sheet between the main surface member 64a is arranged. The size of the holding piece 72 is slightly smaller than the size of the binding passage 68, for example. One end of the holding piece 72 in the width direction is integrally connected to the main surface member 64a via the hinge portion 74. As shown in FIG. 14, the hinge 74 is formed closer to the main surface member 64a than the hinge 66 described above. At this time, the hinge part 66 and the hinge part 74
Is formed to be substantially the same as the thickness of the connecting member 20 of the binding device 10. Therefore, the holding piece 72 is connected to the hinge 7
4, when the main surface member 64b is folded back at the hinge 66, a step corresponding to the thickness of the connecting member 20 of the binding device 10 is generated between the back of the hinge 74 and the back of the hinge 66. Therefore, as described later, the holding piece 7 is
When the main surface member 64b is folded back at the hinge portion 74 and overlapped with the main surface member 64a while holding the binding device 2, the binding device 10
And the back of the file cover 60 are arranged in a straight line. Therefore, it looks good.

As shown in FIG. 14, for example, three rectangular through holes 76 are formed in the holding piece 72 at predetermined intervals in the longitudinal direction of the holding piece 72.
These through holes 76 are provided corresponding to three projecting pieces 23a of the binding device 10 described later. These through holes 76
Is for engaging the projecting piece 23a to prevent the binding tool 10 from being inadvertently detached from the holding piece 72. In addition, these through holes 76 allow the protruding piece 23a of the binding device 10 to be inserted in the thickness direction of the holding piece 72 to abut on the object to be held, so that the object to be held is a pair of the holding members 16a,
This is also to make it difficult for the user to escape from the space between 16b without permission.

The binding member passage 68, the end passage 70, and the holding piece 7
2 and the through hole 76 are formed by punching the central portion of the base sheet 62 into a predetermined shape at the same time as punching the base sheet 62 from a plate-shaped or roll-shaped raw material. At this time, the hinge portion 74 is simultaneously formed by press working. Each of the hinge portions 66 and 74 described above is formed by recessing the main surface of the base sheet 62 into a substantially concave shape in cross-section, similarly to a conventional method for forming a hinge. Things.

As shown in FIG. 14, the main surface member 64a is formed with a mounting hole 78 for pivotally attaching the binding device 10. The attachment hole 78 is formed corresponding to the pivot hole 26 of the binding device 10 to be pivotally connected. On the other hand, an eyelet working hole 80 is formed in the main surface member 64b so as to correspond to the mounting hole 78. As shown in FIG. 16, when the main surface member 64b and the main surface member 64a are overlapped with each other, the eyelet working hole 80 is attached to the main surface member 64b from the front side to the rear surface side of the main surface member 64b. The eyelets 82 can be attached to the holes 78.

Next, with reference to FIG.
0 and the file 100 using the file cover 60 will be described. When assembling the file 100, the main surface member 64b of the file cover 60 is attached to the hinge 66
To overlap the main surface member 64a. Next, the pivot hole 26 of the holding device 10 is attached to the attachment hole 78 of the file cover 60.
Overlaid. Then, the eyelet 82 as a pivot member is passed through the eyelet working hole 80 from the surface side of the main surface member 64b.
