The binding tool 20 includes a substrate 22 that is a plate-like main body constituting a base member formed of a thin metal plate. The linear longitudinal end edge on one end side in the width direction of the substrate 22 is provided with a bearing portion that is an operation member fixing portion, and the bearing portion is integrally formed with a bearing plate 24 that stands upright with respect to the substrate 22 as shown in FIG. Formed. The bearing plate 24 is formed of a vertical plate formed continuously from the front side edge in the longitudinal direction of the substrate 22 to the vicinity of the far side edge. A circular through hole 26 is formed on one end side (the other side) of the bearing plate 24 in the longitudinal direction, and an operation lever described later is fixed to the other end side (the near side) of the bearing plate 24 in the longitudinal direction. A fixing convex portion 28 is formed as a fixing portion. The fixing projection 28 is formed, for example, by forming a quadrangular hole in the bearing plate 24 and extruding the upper part of the hole to the substrate 22 side.

  In the vicinity of the opposite side of the through hole 26 forming portion of the bearing plate 24, a corner portion on one end side in the longitudinal direction of the substrate 22 is cut and raised at an appropriate interval to form the pivotal support portion 30. The main surface of the pivot portion 30 is formed to be orthogonal to the main surface of the bearing plate 24. A circular through hole 32 is formed in the pivot portion 30. Further, another pivotal support portion 34 having a surface parallel to the main surface of the pivotal support portion 30 is formed in the vicinity of the front side of the fixing convex portion 28. The pivot portion 34 is formed by forming a U-shaped notch in the substrate 22 and raising this portion. A circular through hole 36 is formed in the pivot portion 34. The pivot portions 30 and the pivot portions 34 are opposed to each other, and the line connecting the through holes 32 and 36 is arranged to be parallel to the main surface of the bearing plate 24 on the substrate 22 side.

A bearing portion 38 having a smooth surface is formed. The bearing portion 38 is also formed by forming a U-shaped cut in the substrate 22 and raising this portion. A circular through hole 40 is formed in the bearing portion 38, and the through hole 26 of the bearing plate 24 and the through hole 40 of the bearing portion 38 are arranged to face each other. That is, a line connecting the through hole 32 of the pivotal support portion 30 and the through hole 36 of the pivotal support portion 34 and a line connecting the through hole 26 of the bearing plate 24 and the through hole 40 of the bearing portion 38 are orthogonal to each other. It is formed. Further, two convex portions 42 are formed on the other end side in the width direction of the substrate 22. These convex portions 42 are formed side by side in the longitudinal direction of the substrate 22 with a certain interval. A pair of through holes 44 for attaching the binding tool 20 to a file or the like are formed on both sides in the longitudinal direction of the substrate 22 on the far side and the near side.

A shaft 46 is inserted into the through hole 26 of the bearing plate 24 and the through hole 40 of the bearing portion 38, and a spring member 50 formed of a torsion coil spring and an operation lever 60 constituting an operation member are attached to the shaft 46.
The spring member 50 includes a winding portion 50a attached to the outer periphery of the shaft 38, a second end portion 50b extending from one end of the winding portion 50a to the operation lever 60 side substantially parallel to the surface of the bearing plate 24, and A first end portion 50c extending away from the bearing plate 24 in the width direction of the substrate 22 from the winding portion 50a and extending in the binding member 70 side direction.

The second end 50b of the spring member 50 extends linearly from the upper end of the winding portion 50a to the near side on the bearing plate 24 side of the winding portion 50a, and when the tip is not subjected to force, the tip is on the near side. Are formed so as to extend obliquely upward.
The first end portion 50c is substantially L-shaped and extends upward from the lower end of the front side on the bearing portion 38 side of the winding portion 50a to the opposite side of the bearing plate 24. When receiving no force, the first end portion 50c extends upward. A bridging portion 50e extends obliquely upward from the upper end of the rising portion 50d, and a locking portion 50f bent in the horizontal direction protrudes from the free end side of the bridging portion 50e.

The operation lever 60 is formed in a long shape by a metal plate or the like, and is formed in a substantially L-shaped cross section or a substantially U-shaped cross section in order to increase its strength, and the first vertical side wall 60a on the bearing plate 24 side. And a first vertical side wall 60a and a second vertical side wall 60b formed in parallel with a certain distance.
A circular through hole 62 is formed in the first vertical side wall 60 a on one end side in the longitudinal direction of the operation lever 60. The shaft 46 is attached to the bearing plate 24 and the bearing portion 38 so as to pass through the through hole 62 of the operation lever 60 and the winding portion 50a of the spring member 50.
The second end portion 50b of the spring member 50 is disposed along the inner side of the operation lever 60 and is fixed by a bent piece 64 obtained by bending a part of the first vertical side wall 60a of the operation lever 60 inward. Furthermore, a rectangular through hole 66 is formed in the first vertical side wall 60 a of the operation lever 60 at a position corresponding to the fixing convex portion 28 of the bearing plate 24. The fixing projection 28 is fitted and locked in the through hole 66, whereby the operation lever 60 is fixed to the bearing plate 24.
In addition, a wide operation portion 60c is formed on the other end side in the longitudinal direction of the operation lever 60 so that it can be easily operated with a finger.

Further, on the substrate 22, a binding member 70 having a substantially rectangular shape in a plan view extends in the longitudinal direction of the substrate 22 and is attached in parallel to the bearing plate 24, and a longitudinal edge opposite to the bearing plate 24 has a longitudinal edge on the substrate 22. It is formed so as to approach and separate from the surface.
The binding member 70 is formed of, for example, a single metal plate. The binding member 70 has a length substantially equal to the distance between the pivot portions 30 and 34, for example, and is formed in a shape that is bent so as to bulge upward in the width direction (substantially L-shaped in section).
Then, on the bearing plate 24 side in the width direction of the binding member 70, protruding pieces 72 serving as pivots protruding on both sides in the longitudinal direction are formed. These protruding pieces 72 are fitted into the through hole 32 of the pivotal support portion 30 and the through hole 36 of the pivotal support portion 34 that are pivotally supported. Therefore, the binding member 70 can be rotated about the line connecting the two protruding pieces 72 as the rotation center. The protruding piece 72 is formed to bend in the width direction so that the strength of the protruding piece 72 is increased and the protruding piece 72 can easily rotate in the through holes 32 and 36. In this way, by fitting the protruding piece 72 protruding from the binding member 70 into the through holes 32 and 36 of the pivotal support portions 30 and 34, the binding member 70 is rotatably held using a rotating shaft or the like which is a separate part. Compared to the case, the number of parts can be reduced.

  Further, the opposite side of the bearing plate 24 in the width direction of the binding member 70 is bent toward the above-described rotation center side (the protruding piece 72 side) to form a bent portion 74. The bent portion 74 is continuously formed from the near side edge of the binding member 70 to the far side edge. Furthermore, the front end side of the bent portion 74 is bent toward the substrate 22 side, and a pressing portion 76 for pressing the object to be bound X such as a document is formed. The pressing part 76 is continuously formed from the near side edge of the bent part 74 to the far side edge. The pressing portion 76 is formed so as to be inclined toward the rotation center side of the binding member 70 from the bent portion 74 toward the substrate 22 when the binding member 70 is closed to the substrate 22 side. Therefore, the bent portion 74 and the pressing portion 76 are connected in a substantially L shape. The pressing portion 76 presses the object to be bound X such as a document in a straight line. Here, when the binding member 70 is closed to the substrate 22 side, the bent portion 74 rises from the end side of the binding member 70 toward the inside of the binding member 70.

  A rectangular through hole 78 is formed in the bent portion 74, the first end portion 50 c of the spring member 50 is fitted from above, and the distal end portion of the first end portion 50 c of the spring member 50 is bent to form the through hole 78. It is made not to come off. In this embodiment, the through hole 78 is formed at a position near the winding portion 50 a wound around the shaft 46 between the protruding pieces 72 formed at the front and rear ends of the binding member 70. Further, a linear rib 80 is formed in the pressing portion 76 in order to prevent deformation due to a force when the object to be bound X such as a document is pressed.

  As shown in FIGS. 3 and 4, the distal end portion (locking portion 50 f) of the spring member 50 is formed in the width direction of the substrate 22 in both the closed state and the open state. The position in is almost unchanged. When the object to be bound X such as a document to be bound by the binding member 70 is pressed and the operation lever 60 is locked to the fixing convex portion 28, the first end portion 50c of the spring member 50 is extended from the bent state. At the same time, the distal end portion (the locking portion 50f) is twisted and the locking portion 50f is deformed downward from the horizontal state, but the through hole 78 of the bent portion 74 is allowed to allow the deformation state of the spring member 50. It extends in the longitudinal direction and the width direction.

In the locked state where the binding member 70 presses the binding object X, that is, the so-called binding object X is bound, the operation lever 60 is fixed at the lying down position in order to continue the state of pressing the binding object X. .
Further, in the state where the lock for removing the bound object X is released, the operation lever 60 is rotated from the lying down position to the upright state. Then, as the operation lever 60 is moved toward the raised position, the binding member 70 moves upward away from the upper surface of the binding object X.

  The support member 100 is fixed to the substrate 22 so as to be swingable. The assisting member 100 is fixed to the fixing convex portion 28 by the operation lever 60 fixed at the lying position in the locked state in order to continue the state in which the binding member X is pressed by the spring member 50 below the binding member 70. The force is applied in a direction away from the fixed position.

The assisting member 100 pushes the first vertical side wall 60a of the operation lever 60 in the direction away from the bearing plate 24, that is, in the lateral direction away from the fixing convex portion 28 as the fixing portion in the length direction of the operation lever 60. 102, the operation part 104 projecting upward from the lower side of the second vertical side wall 60b on the outer side (binding member side) of the second vertical side wall 60b of the operation lever 60, and the lateral pushing part 102 and the operation part 104. The connecting portion 106 to be connected, and the pivot portion 108 and the pivot portion 110 that are fixed to the substrate 22 to be swingable are provided.
The lateral pushing portion 102 is a plate having a substantially rectangular L-shaped side surface, a lower portion 102a extending obliquely upward from the pivot portions 108 and 110 toward the bearing plate 24, and an upper end of the lower portion 102 from the upper end of the operating lever 60. An upper portion 102b extending between the first vertical side wall 60a and the inner surface of the bearing plate 24 is provided, and the height of the upper portion 102b is substantially the same as the height of the bearing plate 24.
In this way, the lateral pushing portion 102 is interposed between the inner side of the bearing plate 24, that is, the binding member 70 side and the first vertical side wall 60a of the operation lever 60, and the side surface of the bearing plate 24 of the first vertical side wall 60a is the bearing plate. A height and a width for pressing toward the opposite side of 24 are provided.
The operation unit 104 is a plate that extends upward from below (lower) the second vertical side wall 60b of the operation lever 60, and is close to the upper end of the second vertical side wall 60b from a position spaced from the second vertical side wall 60b. The lower portion 104a extending obliquely upward toward the position and the tip thereof are bent toward the operation portion 68 side of the operation lever 60 so as to be easily operated by pushing with a finger, and are substantially the same height as the upper surface of the operation lever 60 The operation surface portion 104b is formed.
The connecting portion 106 has a plate shape that is bridged between the lower portions of the lateral pushing portion 102 and the operation portion 104, and is bound from the pivot portions 108, 110 on the bearing plate 24 side substantially parallel to the upper surface of the substrate 22. It extends obliquely upward on the 70 side and has a width slightly longer than the width of the operation lever 60.
The connecting portion 106 includes a lower portion 106a extending obliquely upward from the pivot portions 108 and 110 toward the opposite side of the bearing plate 24, and an obliquely upward portion extending from the lower portion 106a toward the opposite side of the bearing plate 24. The upper part 106b extends, and the upper end of the upper part 106b and the lower end of the lower part 104a of the operation unit 104 are connected and continuous.

The assisting member 100 is swingable on the upper surface of the substrate 22 and on the lower surface above the operation portion 68 (on the other side) of the operation lever 60 so as to be positioned above (beyond) the operation portion 68 of the operation lever 60. 22 is fixed.
The pivot portions 108 and 110 protrude from the lower side of the lateral pushing portion 102 to the vicinity of the lateral pushing portion 102 of the connecting portion 106 on the far side (upper side) and the near side (lower side).
The pivots 108 and 110 of the assisting member 100 are rotatably fixed to the shaft hole 112a of the pivotal support 112 and the shaft hole 114a of the pivotal support 114 provided on the substrate 22, and the assisting member 100 is a first vertical side wall. The lower part of 60a is pivotally supported so as to be swingable.
The pivot portions 112 and 114 are formed by forming a U-shaped cut in the substrate 22 and raising this portion.
In this embodiment, the pivot portion 34 and the pivot portion 112 that pivotally supports the pivot portion 108 on the upper side (the other side) of the assisting member 100 are integrally formed, and the lower end lower side (front side) of the substrate 22 is formed. A pivot portion 114 that pivots the pivot portion 110 on the lower side (near side) of the assisting member 100 is formed near the end edge.

The assisting member 100 is usually in contact with the pivoting portions 108 and 110 as the center, and the operation portion 104 side is in contact with the upper side of the substrate 22 by being lowered diagonally upward of the lower portion 106a of the connecting portion 106, and the lateral pushing portion. 102 inclines toward the direction away from the bearing plate 24.
When the operation lever 60 is locked, when the free end (operation portion 68) is pushed downward, the first vertical side wall 60a of the operation lever 60 is located on the inner side (the binding member 70 side) of the lateral pushing portion 102. It is lowered and positioned at the lower part of the fixing projection 28 and fixed at the lying position.
At this time, the lateral pushing portion 102 of the assisting member 100 is located in a state substantially parallel to the bearing plate 24, that is, in a substantially vertical shape, and fixes the operation lever 60 in the lying position.

The operation portion 104 of the assisting member 100 is formed with an operation surface portion 104b at substantially the same height as the operation portion 68 of the operation lever 60 when the operation lever 60 is fixed to the fixing convex portion 28 in the locked state. The width 104 is also formed to extend to substantially the same position as the binding member 70 side of the operation portion 68 of the operation lever 60.
The continuous portion 106 is bound from the upper surface of the substrate 22 so that the operation portion 104 is positioned at substantially the same height as the operation lever 60 when the lateral pushing portion 102 is in a position substantially parallel to the bearing plate 24. It is curved so that the 70 side is lifted upward. Then, when the operation portion 104 of the assisting member 100 is pushed downward, the lateral pushing portion 102 swings toward the first vertical side wall 60a of the operation lever 60 with the pivot portions 108 and 110 as pivot points, and the operation lever 60 1 The vertical side wall 60a is pressed to the binding member 70 side.

When the lock is released and the binding object X is removed from the binding member 70, that is, when the binding member 70 is separated from the upper surface of the binding object X, the operation portion 68 of the operation lever 60 and the operation portion 104 of the assisting member 100 are moved. If the finger is simultaneously pushed in the lateral direction (a direction substantially parallel to the upper surface of the substrate 22), the operation lever 60 is moved in the lateral direction, and the assisting member 100 is rotated to move the operation unit 104 downward and laterally push The portion 102 presses the first vertical side wall 60a of the operation lever 60 in the lateral direction (direction substantially parallel to the upper surface of the substrate). Then, the operation lever 60 moves away from the fixing convex portion 28 and gradually moves from the lying position to the rising position where the free end is lifted if the force pushing the operation lever 60 is weakened.
Accordingly, the operation lever 60 is disengaged from the fixing convex portion 28 of the bearing plate 24.

The binding member 70 is not limited to a curved shape, and may be formed in a substantially arcuate cross section formed by bending a metal plate, as shown in FIGS. 10 and 11.
Further, the portion pressed by the pressing portion 76 is not limited to one linear shape, and may be pressed at both ends in the longitudinal direction of the pressing portion 76 as shown in FIG. In this case, the tip of the pressing portion 76 is formed in a shape that is recessed from both ends in the longitudinal direction toward the center. Moreover, as shown in FIG. 13, the recessed part of the longitudinal direction of the press part 76 may be formed, and the to-be-bound objects X, such as a document, may be pressed by several points on a straight line. Further, when the object to be bound X such as a document is pressed at a plurality of locations on a straight line, as shown in FIG. As described above, the portion pressed by the pressing portion 76 may be a single straight line, or may be a point or a linear part at a plurality of locations on the straight line.

  Such a binding tool 20 is attached to a file or the like by, for example, inserting a mounting bracket into a through hole 44 formed in the substrate 22. Then, by operating the operation lever 60, the binding member 70 can be opened and closed. Here, as shown in FIG. 9, by raising the operation lever 60, the other side 50 c of the spring member 50 lifts the binding tool 20, and a gap is generated between the substrate 22 and the pressing portion 76 of the binding member 70. A binding object X such as a document is inserted into the gap, and the binding member 70 is closed by lowering the operation lever 60, and the binding object X such as a document is pressed against the substrate 22 by the pressing portion 76. That is, by lowering the operation lever 60, the winding portion 50 a of the spring member 50 is tightened, and the pressing portion 76 is biased toward the substrate 22 by the first end portion 50 c of the spring member 50.

  At this time, as shown in FIG. 15, the pressing portion 76 is obliquely pressed against the binding object X such as a document. When a force that pulls out the object to be bound X such as a document is applied, a force opposite to the inclination direction of the pressing portion 76 is applied, and the bent portion 74 and the bent portion of the pressing portion 76 are further bent. Directional force is added. Such a force that causes the deformation of the bent portion 74 and the pressing portion 76 to return to the original state adds a force that acts as a resistance force against the pull out of the binding object X such as a document from the pressing portion 76, such as a document. This makes it difficult for the object X to be detached from the binding tool 20.

  Further, since the pressing portion 76 is inclined toward the rotation center side of the binding member 70 as it goes from the bent portion 74 toward the substrate 22 side, as shown in FIG. Even if the thickness is increased, the binding portion X is slightly standing as compared with the case where the binding object X such as a document is thin, but the pressing portion 76 is less likely to be orthogonal to the surface of the binding object X such as a document. It is possible to maintain the resistance against dropping of the object to be bound X such as a document.

  The shape of the pressing portion 76 is not limited to the shape in which the end portion of the binding member 70 is bent, and the tip portion of the curved plate-shaped binding member 70 may be the pressing portion 76 as shown in FIG. In this case, if the cross-sectional shape of the binding member 70 is a semicircular shape or the like, as shown in FIG. 18, the binding object X such as a document is relative to the surface of the binding object X such as a document regardless of the thickness. There is not much change in the angle of the pressing portion 76. Therefore, the binding member 70 as a whole can counteract the force applied in the pulling direction of the binding object X such as a document, and the binding object X such as a document is difficult to come off. On the other hand, as shown in FIG. 19, when the cross-sectional shape of the binding member 70 is a shape bent into a rectangle, when the binding object X such as a document becomes thick, the pressing portion 76 causes the binding object X such as a document to become thick. Therefore, the resistance to the force applied to the binding object X such as a document is weak and the binding object X such as a document is easily detached. Therefore, when the pressing portion 74 is formed without bending the front end portion of the binding member 70, the cross-sectional shape of the binding member 70 is preferably a curved shape such as a semicircle.

  Further, when the binding member 70 is bent to form the pressing portion 76, as shown in FIG. 20, the front end portion of the binding member 70 may be bent only once to the rotation center side to form the pressing portion 76. In this case, the bent portion 74 is not formed, but when a force that pulls out the binding object X such as a document is applied, a force opposite to the inclination direction of the pressing portion 76 is applied, and the pressing portion 76 rises. It deforms as follows. For this reason, it is possible to obtain a resistance against pulling out the binding object X such as a document by the force that the deformation of the pressing portion 76 tries to return to the original state. In addition, in the binding tool 20 having the pressing portion 76 as shown in FIGS. 17, 19, 20, etc., as shown in FIGS. 12 to 14, the portion pressed by the pressing portion 76 is one linear shape. It may be a point or a linear part at a plurality of locations on a straight line.

  When the binding member 70 is opened, as shown in FIGS. 21A and 21B, if the height H of the pressing portion 76 from the substrate 22 is the same, the width of the binding member 70 is larger. On the surface, the deviation X from the closed position becomes small. Therefore, when binding the binding object X such as a document, there is little error from the position of the pressing portion 76 when the binding member 70 is opened to the binding position of the binding object X such as a document, and the binding object such as a document is obtained. Binding of X can be facilitated.

  In the above-described embodiment, the end portion 50c on the fixed side of the spring member 50 to the binding member 70 is formed at a position close to the bearing plate 24, but a force is applied as a whole in the longitudinal direction of the pressing portion 76. Therefore, the end portion 50c on the fixed side of the spring member 50 to the binding member 70 may be fixed in the vicinity of the center of the bent portion 74 in the longitudinal direction.

  As described above, in the binding tool 20 according to the embodiment of the present invention, the binding member 70 operates at the binding position of the object to be bound X such as a document, so that the document can be accurately held at a predetermined position. It is. Further, since the spring member 50 biases the vicinity of the pressing portion 76 on the distal end side of the binding member 70, the pressing force of the spring member 50 is efficiently applied to the pressing portion 76 by operating the operation lever 60. It becomes difficult to remove the binding object X such as a document.

The connecting portion 306 is a plate-like member that is spanned between the lower portions of the lateral pushing portion 302 and the operation portion 304, and is bound from the pivot portions 308 and 310 on the bearing plate 224 side substantially parallel to the upper surface of the substrate 222. It extends obliquely upward on the 270 side and has a width slightly longer than the width of the operation lever 260.
The connecting portion 306 includes a lower portion 306a extending obliquely upward from the pivot portions 308, 310 toward the opposite side of the bearing plate 224, and an obliquely upward portion extending from the lower portion 306a toward the opposite side of the bearing plate 224. The upper portion 306b extends, and the upper end of the upper portion 306b and the lower end of the lower portion 304a of the operation unit 304 are connected and continuous.

The assisting member 300 is swingable on the upper surface of the substrate 222 and on the lower surface above the operation portion 268 (on the other side) of the operation lever 260 so as to be positioned above (beyond) the operation portion 268 on the operation lever 260. 222 is fixed.
The pivot portions 308 and 310 are formed on the far side (upper side) and the near side (lower side) at a position extending from the lower portion of the lateral pushing portion 302 to the vicinity of the lateral pushing portion 302 of the connecting portion 306.
The pivoting portions 308 and 310 of the assisting member 300 are rotatably fixed to pivotal portions 312 and 314 provided on the substrate 222, and the assisting member 300 is pivotally supported at the lower portion of the first vertical side wall 260a. Has been.
The pivot portions 312 and 314 are formed by forming a U-shaped cut in the substrate 222 and cutting and raising this portion, and are formed into a substantially inverted L-shaped side surface.
In this embodiment, the pivot member 312 pivotally supports the pivot member 308 on the upper side (the other side) of the assist member 300, and the vicinity of the edge on the lower lower side (front side) of the substrate 222. The lower side (front side) pivotal support part 310 is provided so as to face the pivotal part 314 that pivots.

The assisting member 300 is in contact with the pivoting portions 308 and 310 as the center, and the operation portion 304 side is always in contact with the upper surface of the substrate 222 by being lowered diagonally above the lower portion 306b of the connecting portion 306. 302 is inclined in a direction away from the bearing plate 224.
When the operation lever 260 is locked, when the free end (operation portion 268) is pushed downward, the first vertical side wall 260a of the operation lever 260 is located on the inner side (the binding member 270 side) of the lateral push portion 302. It is lowered and is positioned at the lower part of the fixing projection 228 and fixed at the lying position.
At this time, the lateral pushing portion 302 of the assisting member 300 is positioned in a state substantially parallel to the bearing plate 224, that is, in a substantially vertical shape, and fixes the operation lever 260 in the lying down position.

The operation portion 304 of the assisting member 300 is formed with an operation surface portion 304b at a height slightly above the operation portion 268 of the operation lever 260 when the operation lever 260 is fixed to the fixing convex portion 228 in the locked state. The width of the portion 304 is formed so as to extend to substantially the same position as the binding member 270 side of the operation portion 268 of the operation lever 260.
The continuous portion 306 is positioned so that the operation portion 304 is positioned slightly above the operation portion 268 with the operation lever 260 when the lateral pushing portion 302 is in a position substantially parallel to the bearing plate 224. The binding member 270 is bent upward from the upper surface of the substrate 222 so as to be lifted upward. When the operation portion 304 of the assisting member 300 is pushed downward, the lateral pushing portion 302 swings toward the first vertical side wall 260a of the operation lever 260 with the pivot portions 308 and 310 as pivot points, and the operation lever 260 1 The vertical side wall 260a is pressed to the binding member 270 side.

When the lock is released and the binding object X is removed from the binding member 270, that is, when the binding member 270 is separated from the upper surface of the binding object X, the operation unit 268 of the operation lever 260 and the operation unit 304 of the assisting member 300 are moved. If the finger is simultaneously pushed in the lateral direction (a direction substantially parallel to the upper surface of the substrate 222), the operation lever 260 is moved in the lateral direction, the assisting member 300 is rotated and the operation unit 304 is lowered downward and the lateral pushing unit. 302 presses the first vertical side wall 260a of the operation lever 260 in the lateral direction (direction substantially parallel to the upper surface of the substrate). Then, the operating lever 260 moves away from the fixing convex portion 228 and gradually moves from the lying position to the rising position where the free end is lifted if the force pushing the operating lever 260 is weakened.
Therefore, the operation lever 260 is detached from the fixing convex portion 228 of the bearing plate 224 with good operability.

The base plate 222 is formed with a note aligning portion 290 having a surface parallel to the surface of the bearing plate 224 for aligning the edge of the object to be bound X such as a document to be bound, outside the protruding piece 272 of the pivot portion 234. Yes.
The note aligning portion 290 is also formed by forming a U-shaped cut in the substrate 222 and cutting this portion up.
The pivot portion 234 is formed so that the edge opposite to the bearing plate 224 is aligned on the same plane (imaginary) as the surface of the note aligning portion 290 opposite to the bearing plate 224.
Therefore, the edge of the pivotal support part 234 can be used as a guide, and the edge of the object to be bound X such as a document to be bound to the note aligning part 290 can be brought into contact with and bound.

  Such a binding tool 220 is attached to a file or the like by inserting a mounting bracket or the like through a through hole 244 formed in the substrate 222, for example. The binding member 270 can be opened and closed by operating the operation lever 260. Here, as shown in FIG. 22, by raising the operation lever 260, the other side 250 c of the spring member 250 lifts the binding tool 220, and a gap is generated between the substrate 222 and the pressing portion 276 of the binding member 270. A binding object X such as a document is inserted into the gap, and the binding member 270 is closed by lowering the operation lever 260, and the binding object X such as a document is pressed against the substrate 222 by the pressing portion 276. That is, by lowering the operation lever 260, the winding portion 250 a of the spring member 250 is tightened, and the pressing portion 276 is biased toward the substrate 222 by the first end portion 250 e of the spring member 250.

  At this time, as shown in FIG. 32, the pressing portion 276 is pressed obliquely against the object to be bound X such as a document. When a force that pulls out the object to be bound X such as a document is applied, a force opposite to the inclination direction of the pressing portion 276 is applied, and the bent portions 274 and the bent portions of the pressing portion 276 are further bent. Directional force is added. By such force that the deformation of the bent portion 274 and the pressing portion 276 is returned to the original state, the pressing portion 276 applies a force that resists pulling out the binding object X such as a document, and the like. This makes it difficult for the object X to be detached from the binding tool 220.

  Further, since the pressing portion 276 is inclined so as to go to the rotation center side of the binding member 270 as it goes from the bent portion 274 to the substrate 222 side, as shown in FIG. Even if the thickness of the object to be bound is thin, the pressing portion 276 is less likely to be perpendicular to the surface of the object to be bound X such as a document. It is possible to maintain the resistance against dropping of the object to be bound X such as a document.
