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.
Further, a rectangular engagement 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 engaging hole 66 constitutes a fixing portion together with the fixing convex portion 28, the fixing convex portion 28 is fitted into the engaging hole 66, and the lower end edge 66 a ₁ of the engaging hole 66 is the lower end of the fixing convex portion 28. The operation lever 60 is fixed to the bearing plate 24 by being engaged with the edge 28a. 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.

It rises once the lowered operating lever 60 slightly below, are configured to lower edge 66a ₁ of the engagement hole 66 is engaged.
The fixing convex portion 28 has a width so as to be disengaged from the engagement hole 66 of the operation lever 60 before the first vertical side wall 60 a and the second vertical side wall 60 b of the operation lever 60 reach the surface of the substrate 22. .

When the operation lever 60 is pushed downward toward the substrate 22 to release the lock, the operation lever 60 is in contact with the operation lever 60 and is directed toward the substrate 22 in a direction away from the fixing projection 28. A guide portion 128 is formed for guidance.
On the other hand, the engaging hole 66 of the first vertical side wall 60a, the upper edge 66a ₂ is, when depressed to unlock the locked operating lever 60 in the locked state, the top of the convex fixing part 28 The lower end edge 60a ₁ of the first vertical side wall 60a is opened so as to contact the uppermost part 128a of the guide part 128 without contacting the 28b.

The guide portion 128 is provided so as to protrude from the inner surface of the upright plane of the bearing plate 24 that fixes the shaft 46, and is inclined from the lower portion of the fixing convex portion 28 toward the upper surface of the substrate 22. It is formed so that it goes down as it goes to.
When the operation lever 60 is slid along the guide portion 128 and lowered, the guide portion 128 can guide the engaging hole 66 of the first vertical side wall 60a to a position where it is disengaged from the fixing convex portion 28. Further, the ridge line portion has a mountain-shaped guide line portion extending from the bearing plate 24 to the operation lever 60 side, with a protruding width longer than the protruding width of the fixing convex portion 28.
Further, the guide portion 128 is a length between the lower end edge 66a ₁ of the engagement hole 66 of the operation lever 60 and the lower end edge 60a ₁ of the first vertical side wall 60a of the operation lever 60 under the fixing convex portion 28. It protrudes from a position that is further lowered.
The guide portion 128 is provided with a second end portion for guiding the operation lever 60 that has started to be pushed down against the pushing force of the second end portion 50b of the spring member 50 in order to remove the guide portion 128 from the fixing convex portion 28. It is formed so as to protrude obliquely downward, which is a direction intersecting a vertical plane passing through 50 b, and the lower end of the guide portion 128 reaches a position close to the upper surface of the substrate 22.

In this embodiment, the guide portion 128 is operated by punching, for example, a U-shaped hole in the flat plate-like bearing plate 24 and operating the inside of the U-shaped punched hole, like the convex portion 28 for fixing. It is stamped on the lever 60 side and formed into a mountain shape.
The guide portion 128 is guided portion or ridge to the lower edge 60a ₁ and contact the guide of the first vertical side wall 60a of the operation lever 60 is a linear projecting upward, sliding easily planar Alternatively A guide surface portion may be formed.

Further, on the substrate 22, a binding member 70 having a substantially rectangular shape in plan view extends in the longitudinal direction of the substrate 22 and is attached in parallel with the bearing plate 24. 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 (a semicircular cross-sectional shape) that curves so as to bulge upward in the width direction.
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.

The second end portion 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, and when the tip is not subjected to an external force, the tip is on the near side. Are formed so as to extend obliquely upward.
The first end portion 50c has a substantially L-shape extending from the lower end on the front side of the winding portion 50a to the opposite side to the bearing plate 24, and extends upward when receiving no external force. 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.

  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 both when the binding member 70 is in the closed state and in 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.

  Note that the portion pressed by the pressing portion 76 is not limited to a single 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. 11, 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. Furthermore, 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. 1, 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. 13, 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.

  Furthermore, 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.

  Note that 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. 16, 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. 17, 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. 18, 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. 15, 17, 18, etc., as shown in FIGS. 6 to 8, 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. 19A and 19B, if the height H of the pressing portion 76 from the substrate 22 is the same, the larger the binding member 70 is, the larger the width of the substrate 22 is. 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 front end side of the binding member 70, the force is efficiently applied to the pressing portion 76 by operating the operation lever 60, and the object to be bound such as a document. X becomes difficult to come off.

The present invention is not limited to the above-described embodiment, and various modifications can be made based on the idea of the present invention.

It is formed. In addition, two convex portions 242 are formed on the other end side in the width direction of the substrate 222. These convex portions 242 are formed side by side with a certain interval in the longitudinal direction of the substrate 222. A pair of through holes 244 for attaching the binding tool 220 to a file or the like are formed on both sides in the longitudinal direction of the substrate 222 on the far side and the near side.

A shaft 246 is inserted through the through hole 226 of the bearing plate 224 and the through hole 240 of the bearing portion 238, and a spring member 250 made of a torsion coil spring and an operation lever 260 constituting the operation member are attached to the shaft 246.
The spring member 250 includes a winding portion 250a mounted on the outer periphery of the shaft 238, a second end portion 250b extending from one end of the winding portion 250a to the operation lever 260 side substantially parallel to the surface of the bearing plate 224, A first end portion 250c extending away from the bearing plate 224 in the width direction of the substrate 222 from the winding portion 250a and extending in the binding member 270 side direction.

The second end portion 250b of the spring member 250 linearly extends from the upper end of the winding portion 250a to the near side on the bearing plate 224 side of the winding portion 250a. Are formed so as to extend obliquely upward.
The first end portion 250c is substantially L-shaped and extends upward from the lower end on the bearing portion 238 side of the winding portion 250a on the opposite side to the bearing plate 224, and extends upward when receiving no force. A bridging portion 250e extends obliquely upward from the upper end of the rising portion 250d, and a locking portion 250f that is bent in the horizontal direction protrudes from the free end of the bridging portion 250e.

The operation lever 260 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 260a on the bearing plate 224 side. And a first vertical side wall 260a and a second vertical side wall 260b formed in parallel with a certain distance.
A circular through hole 262 is formed in the first vertical side wall 260 a on one end side in the longitudinal direction of the operation lever 260. The shaft 246 is attached to the bearing plate 224 and the bearing portion 238 so as to be inserted into the through hole 262 of the operation lever 260 and the winding portion 250 a of the spring member 250. The second end portion 250b of the spring member 250 is disposed along the inner side of the operation lever 260 and is fixed by a bent piece 264 obtained by bending a part of the first vertical side wall 260a of the operation lever 260 inward. Further, a rectangular engagement hole 266 is formed in the first vertical side wall 260 a of the operation lever 260 at a position corresponding to the fixing convex portion 228 of the bearing plate 224. The engaging hole 266 constitutes a fixing part together with the fixing convex part 228, the fixing convex part 228 is fitted into the engaging hole 266, and the lower end edge of the engaging hole 266 is the lower end of the 260 a ₁ fixing convex part 228. The operating lever 260 is fixed to the bearing plate 224 by being engaged with the edge 228a. In addition, a wide operation portion 260c is formed on the other end side in the longitudinal direction of the operation lever 260 so that it can be easily operated with a finger.
When the free end of the operating lever 260 is lowered with the shaft 246 as a pivot to push down the binding member 270 toward the binding object X, the fixing convex portion 228 is more than the lower end edge 228a of the fixing convex portion 228. The operation lever 260 once lowered downward is slightly raised so that the lower edge 266a ₁ of the engagement hole 266 is locked.
Note that the fixing convex portion 228 has a width so as to be disengaged from the engagement hole 266 of the operation lever 260 before the first vertical side wall 260a and the second vertical side wall 260b of the operation lever 260 reach the surface of the substrate 222. .

When the operation lever 260 is pushed downward toward the substrate 222 to release the lock, the operation lever 260 comes into contact with the operation lever 260 and is directed toward the substrate 22 in a direction to remove from the fixing convex portion 228. A guide portion 328 for guiding is formed.
On the other hand, when the upper end edge 266a ₂ of the engagement hole 266 of the first vertical side wall 260a pushes down the operation lever 260 locked in the locked state to release the lock, the uppermost portion of the fixing convex portion 228 is as lower edge 260a ₁ of the first vertical side wall 260a is in contact with the top of the guide portion 328 without impinge on 128a, is opened.

The guide portion 328 is provided so as to protrude from the inner surface of the upright plane of the bearing plate 224 that fixes the shaft 246, and is inclined from the lower portion of the fixing convex portion 228 toward the upper surface of the substrate 222, and is bound to the binding member 270 side. It is formed so that it goes down as it goes to.
The guide part 328 can guide the engaging hole 266 of the first vertical side wall 260a to a position where it is disengaged from the fixing convex part 228 when the operation lever 260 is slid along the guide part 328 and lowered. Further, the ridge line portion has an angled guide line portion extending from the bearing plate 224 to the operation lever 260 side, with a protruding width longer than the protruding width of the fixing convex portion 228.

It protrudes from a position that is further lowered.
The guide portion 328 has a second end portion for guiding the operation lever 260 that has started to be pushed down against the push-down force of the second end portion 250b of the spring member 250 in order to remove it from the fixing convex portion 228. It is formed so as to protrude obliquely downward, which is a direction intersecting the vertical plane passing through 250 b, and the lower end of the guide portion 328 reaches a position close to the upper surface of the substrate 222.

In this embodiment, the guide portion 328 is formed by punching, for example, a U-shaped hole in the flat plate-like bearing plate 224 and operating the inside of the U-shaped punching hole, like the fixing convex portion 228. It is stamped on the lever 260 side and formed into a mountain shape.
The guide portion 328 is a guide portion that contacts and guides the lower end edge of the first vertical side wall 260a of the operation lever 260, that is, a linear shape in which a ridge line portion protrudes upward. Instead, a planar guide surface portion that easily slides. May be formed.

Further, a binding member 270 having a substantially rectangular shape in plan view is attached to the substrate 222 so as to extend in the longitudinal direction of the substrate 222 and to be parallel to the bearing plate 224. The binding member 270 is formed of, for example, a single metal plate. The binding member 270 has a length substantially equal to the distance between the pivot portions 230 and 234, for example, and is formed in a shape that is bent so as to bulge upward in the width direction (substantially L-shaped in cross section).
Then, on the bearing plate 224 side in the width direction of the binding member 270, a protruding piece 272 that is a pivot protruding on both sides in the longitudinal direction is formed. These projecting pieces 272 are fitted into the through hole 232 of the pivotal support 230 that is a pivotal bearing and the through hole 236 of the pivotal support 234 that is a pivotal bearing. Therefore, the binding member 270 can be rotated around the line connecting the two protruding pieces 272. The protruding piece 272 is formed to bend in the width direction so that the strength of the protruding piece 272 is increased and the protruding piece 272 is easily rotated in the through holes 232 and 236. In this way, by fitting the protruding piece 272 protruding from the binding member 270 into the through holes 232 and 236 of the pivotal support portions 230 and 234, the binding member 270 is rotatably held using a rotating shaft or the like as a separate part. Compared to the case, the number of parts can be reduced.

  Further, the opposite side of the bearing plate 224 in the width direction of the binding member 270 is bent by approximately 20 ° with respect to the horizontal plane toward the above-described rotation center side (projection piece 272 side), and a bent portion 274 is formed. The bent portion 274 is continuously formed from the near side edge of the binding member 270 to the far side edge. Furthermore, the front end side of the bent portion 274 is bent toward the substrate 222 side, and a pressing portion 276 for pressing the object to be bound X such as a document is formed. The pressing part 276 is formed continuously from the near side edge of the bent part 274 to the far side edge. The pressing portion 276 is formed to be inclined toward the rotation center side of the binding member 270 as it goes from the bent portion 274 toward the substrate 222 when the binding member 270 is closed to the substrate 222 side. Therefore, the bent part 274 and the pressing part 276 are connected in a substantially L shape. By this pressing portion 276, the object to be bound X such as a document is pressed in a straight line. Here, when the binding member 270 is closed to the substrate 222 side, the bent portion 274 rises from the end side of the binding member 270 toward the inside of the binding member 270.

As shown in FIG. 29, the binding member 270 includes a rising portion 270a extending obliquely upward from the protruding piece 272 side on the side opposite to the bearing plate 224, and a diagonally lower side from the upper end of the rising portion 270a (approximately 22 with respect to the horizontal plane). ), And a bent portion 274 and a pressing portion 276 formed at the free end of the bridge portion 270b. The rising portion 270a, the bridge portion 270b, and the bent portion 274 are provided. And the press part 276 is integrally formed.
A bending portion 270c is formed at the free end of the bridging portion 270b by being bent obliquely downward (approximately 15 ° with respect to the vertical surface) from the front side edge of the binding member 270 to the far side edge. Has been. A bent portion 274 is continuously provided at the free end of the bent portion 270c, and the bent portion 274 is formed substantially parallel to the bridging portion 270b at a certain interval, and holds the object to be bound X such as a document. The pressing portion 276 is formed so as to be able to press the binding object X such as a document while being slightly bent toward the bridging portion 270b.
The rising portion 270a of the binding member 270 has an inclined surface (relative to the vertical surface) that expands toward the upper side so as to secure a space where the operation lever 260 can be removed from the fixing convex portion 228. A surface inclined by approximately 45 ° is formed.

  The spring member 250 is formed such that the first end portion 250c is similar to the inner surface of the binding member 270, the rising portion 250d of the spring member 250 is in the vicinity of the inner surface of the rising portion 270a of the binding member 270, and the spring member 250 is bridged. The binding member 270 is provided on the inner surface side so that the portion 250e is positioned near the inner surface of the bridging portion 270b of the binding member 270.

  A rectangular through hole 278 is formed in the bent portion 274, and the first end portion 250c of the spring member 250 is fitted from the bridging portion 270b side, and the tip end portion (locking) of the first end portion 250c of the spring member 250 is engaged. The portion 250f) is bent so as not to be detached from the through hole 278. In this embodiment, the through hole 278 is formed at a position close to the winding portion 250 a wound around the shaft 246 between the protruding pieces 272 formed at the front and rear ends of the binding member 270. Further, a linear rib 280 is formed on the pressing portion 276 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 FIG. 30, the distal end portion (locking portion 250 f) of the spring member 250 is positioned in the width direction of the substrate 222 both when the binding member 270 is in the closed state and in the open state. Is almost unchanged. When the object to be bound X such as a document to be bound by the binding member 270 is pressed and the operation lever 260 is locked to the fixing convex portion 228, the first end portion 250c of the spring member 250 is extended from the bent state. At the same time, the tip (locking portion 250f) is twisted and the locking portion 250f is deformed downward from the horizontal state, but the through-hole 278 is formed in the bent portion 274 so that the deformed state of the spring member 250 can be allowed. It extends in the longitudinal direction and the width direction.

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. Then, the binding member 270 can be opened and closed by operating the operation lever 260. Here, as shown in FIG. 20, 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 c of the spring member 250.

  At this time, as shown in FIGS. 31 and 32, the pressing portion 276 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 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 be directed toward the rotation center side of the binding member 270 from the bent portion 274 toward the substrate 222 side, as shown in FIGS. Even if X is thicker, it is slightly stiff compared to when the object to be bound X such as a document is thin, but the pressing portion 276 is at a position orthogonal to the surface of the object to be bound X such as a document. It is difficult to maintain the resistance against dropping of the object to be bound X such as a document.
