Description

  The present invention relates to a binding machine referred to as a so-called stapleless stapler that does not use a metal needle among binding machines that integrally bind the ends of a plurality of stacked sheets.

  Conventionally, as a binding machine of this type, a plurality of sheets of paper are arranged between an anvil and a cutting blade and a cutting blade, and the cutting blade and the cutting blade are moved in the anvil direction so as to penetrate the paper. A punching hole and a cut hole are formed in the paper by the cooperation of the punching blade and the cutting blade and the anvil, and the cut and raised pieces cut out from the punching hole are inserted into the cut hole so that the paper is mutually connected. A binding machine that can perform binding is known (for example, see Patent Document 1).

  In such a binding machine, there is a demand for making a cut hole or a punched hole in a complicated shape in order to make various variations of the binding method. When it is going to satisfy this demand, it is anticipated that the operation | movement which inserts a cutting-and-raising piece into a cut hole will be prevented by presence of an anvil, and it may be unable to implement. If the shape of the anvil is simplified in order to solve this problem, there is a dilemma that the backing of the paper is not sufficiently maintained when the cut holes and punched holes are drilled, and the cut holes and punched holes cannot be formed well. Yes, some countermeasure was desired.

The tip of each arm portion 631 is connected to the movable anvil portion 92 via the connect pin 971. The connecting portion 632 is formed with a slit 637 extending in the advancing and retracting direction of the punching blade 7 and the cutting blade 8. The slit 637 is open to the upper end side of the connection portion 632. The shaft 64 can move freely along the long hole 635 in a region until the cutting blade 8 and the cutting blade 7 reach the switching position (L), and the long hole 635 in the switching position (L). It is set so that it abuts on the one end portion 636.

  As shown in FIGS. 3, 5, 6, 8, 9, and 14 to 17, the movable anvil portion operation restriction mechanism 62 is configured so that the cutting blade 8 and the cutting blade 7 are in the switching position (L The engagement member 65 that engages with the connector 61 in the region up to () and prohibits the movement of the connector 61 and the engagement of the engagement member 65 with the connector 61 in the region beyond the switching position (L) are released. And a disengagement portion 66 that performs. The locking member 65 has a claw portion 651 that engages with the upper end of the connection portion 632 in the connector main body 63. The locking member 65 is attached to the base portion 2 via a shaft, and is always biased by a torsion coil spring S4 that is a biasing means in a direction in which the claw portion 651 is engaged with the connector 61. The disengagement portion 66 has an inclined surface 661 provided on the locking member 65 and a connector detaching the claw portion 651 of the locking member 65 against the urging force of the torsion coil spring S4 by contacting the inclined surface 661.

Specifically, the release member 662 has a convex shape that extends integrally from the rear end of the slide member 31, and is provided so as to be movable in a slit 637 provided in the connector 61 without interfering with the connector 61. It is a thing.

  Note that the inner cam rotation mechanism K1 in the present invention means that the inner cam 32 is extracted until the cam rotation start position (R) at which the punching blade 7 and the cutting blade 8 penetrate the sheet P reaches a predetermined value. The inner cam 32 is rotated in a region where the amount of penetration exceeds a predetermined value, and the cut and raised piece P11 is inserted into the window 85 provided in the cutting blade 8. In this embodiment, the inner cam 32, a shaft 71 that rotatably supports the inner cam 32, a locking portion 332 that is provided on the pusher 33 and locks the arm 322 of the inner cam 32, and the inner cam 32 A coil spring S3 that biases the arm 322 of the cam 32 in the initial posture (F) direction is mainly configured, and the upper surface of the arm 322 is in contact with the locking portion 332 at the cam rotation start position (R). It is adapted to be abutted and locked.

  Further, the binding machine 1 of the present embodiment includes a blade driving mechanism K2, and the blade driving mechanism K2 uses the operation force applied to the operation handle 4 to move the punching blade 7 and the cutting blade 8 in the vertical direction. It is intended to operate. More specifically, a slide member 31 that holds the punching blade 7 and the cutting blade 8 and can be moved up and down with respect to the base portion 2, and an operating force applied to the operation handle 4 for the slide member 31. A blade driving mechanism K3 that causes the punching blade 7 and the cutting blade 8 to move upward to a punching position (C) that penetrates the paper P, and the sliding blade 31 and the cutting blade 8 are extracted from the paper P. And a blade extraction mechanism K4 for returning to the retracted position (S).

  More specifically, the blade driving mechanism K3 uses the operation force applied to the operation handle 4 to move the slide blade 31 holding the cutting blade 7 and the cutting blade 8 upward, so that the cutting blade 7 and the cutting blade 8 are made to penetrate the paper P set in the gap 253 on the upward surface 252 side of the base portion 2, and the slide member 31 that holds the cutting blade 7 and the cutting blade 8, An operation handle 4 for raising the slide member 31 by an operating force applied from the outside and a drive shaft 313 for transmitting the operation to the operation handle 4 to the slide member 31 are mainly configured.

  Further, the blade extraction mechanism K4 of the present embodiment includes a plurality of coil springs that are elastic members that urge the slide member 31 holding the extraction blade 7 and the cutting blade 8 downward with the base portion 2 as a scaffold. S1 is the main component.

  Note that if the slide member 31 and the operation handle 4 are connected by the drive shaft 313 as in this embodiment, the performance of the blade extraction mechanism K4 can be further improved. That is, even when the number of sheets P increases and the cut and raised piece P11 cannot be pulled out to the one surface Pa side of the sheet P only by the force of the coil spring S1, an upward operating force is applied to the operation handle 4. Thus, the drawing can be completed.

  Next, the operation of the binding machine 1 will be described with reference to FIGS. 14 and FIG. 18, FIG. 15 and FIG. 19, FIG. 16 and FIG. 20, and FIG.

  In a state where the operation handle 4 is not operated, as shown in FIGS. 14 and 18, the slide member 31 is positioned at the lower limit position, and the punching blade 7 and the cutting blade 8 are held at the retracted position (S). The inner cam 32 maintains the initial posture (F) accommodated in the punching blade 7 held at the retracted position (S). Further, the claw portion 651 is engaged with the upper end of the connector main body 63, and the movable anvil portion 92 is held at the drilling position (C) where it overlaps the stationary anvil portion 91. Further, the shaft 64 of the anvil portion driving means 6 is movably disposed in the long hole 635 of the connector main body 63, and a certain distance is secured between the upper end portion of the long hole 635.

  In this state, a plurality of overlapped sheets P are inserted to the back of the sheet insertion gap 253 formed between the upward surface 252 of the base portion 2 and the downward surface of the stationary anvil portion 91. When the operation handle 4 is operated downward, the force applied to the operation portion 41 of the operation handle 4 is converted into an upward movement of the slide member 31 through the arm 42 of the operation handle 4 and transmitted. More specifically, when the operation handle 4 is operated downward, the arm 42 of the operation handle 4 rotates about the shaft 44. As a result, the base end portion on the rotating end side of the arm 42 moves forward and upward. And the force which operated the operation handle 4 below is transmitted to the drive shaft 313 pivotally attached to this base end part, and the urging force of the coil spring S1 arranged between the base part 2 and the slide member 31 is transmitted. Accordingly, the slide member 31 is moved upward.

  When the slide member 31 starts to move upward, the entire blade unit 3 including the punching blade 7 and the cutting blade 8 held by the slide member 31 is raised while compressing the coil springs S1 and S2.

  Thereafter, when the slide member 31 is raised, the pusher 33 is urged upward via the coil spring S2 to press the paper P. As a result, the paper P is pressed against the anvil 9 by the paper presser 331 of the pusher 33. Then, in a state where the paper P is pressed against the anvil 9 by the paper presser 331, the leading edge of the punching blade 7 and the cutting blade 8 attached to the slide member 31 rises to a position where the leading edge of the paper P abuts against one surface Pa of the paper P. To do. At this time, the movable anvil portion 92 of the anvil 9 is located at the punching position (C), and the stationary anvil portion 91 and the movable anvil 9 cooperate to support the paper P.

  When the operation handle 4 is further moved downward from this position, as shown in FIGS. 15 and 19, the paper P in the vicinity where the punching blade 7 and the cutting blade 8 penetrate is firmly fixed by the paper presser 331. In this state, the punching blade 7 and the cutting blade 8 penetrate the paper P, and a punching hole P1 and a cut hole P2 are punched in the paper P.

  As the slide member 31 moves upward, the shaft 64 provided on the slide member 31 and engaged with the elongated hole 635 of the connector main body 63 also moves upward. The shaft 64 moves up and down along a long hole 635 provided in the connector main body 63 in a region until the cutting blade 8 and the cutting blade 7 reach the switching position (L). Therefore, the movable anvil part 92 is not actively driven upward. In addition, when the punching blade 7 and the cutting blade 8 pass through the paper P, an upward force is also applied to the movable anvil portion 92, but the connector 61 is locked by the locking member 65. The movable anvil portion 92 is prohibited from moving upwardly during drilling. In other words, the locking member 65 which is a part of the movable anvil portion movement restricting mechanism 62 is engaged with the connector 61 in a region until the cutting blade 8 and the cutting blade 7 reach the switching position (L). Since the movement of the connector 61 is prohibited, even if the slide member 31 moves upward, the connector 61 starts moving until just before the cutting blade 8 and the cutting blade 7 reach the switching position (L). There is no. More specifically, the anvil 9 holds the movable anvil portion 92 at the punching position (C) until the switching position (L) where the amount of penetration of the punching blade 7 and the cutting blade 8 with respect to the paper P reaches a certain value. It keeps the state.

  16 and 20, immediately before the punching blade 7 and the cutting blade 8 reach the switching position (L), that is, the penetration amount of the punching blade 7 and the cutting blade 8 with respect to the paper P becomes a constant value. Slightly before reaching, the restriction by the movable anvil part movement restriction mechanism 62 is released. Specifically, as the slide member 31 is raised, the release member 662 provided on the slide member 31 moves upward in the slit 637 of the connector body 63, and the release member 662 is moved to the locking member. By pressing the inclined surface 661 of 65, the biasing of the torsion coil spring S4 of the locking member 65 is released, and the engagement of the locking member 65 with the connector 61 is released. And the upward prohibition state of the movable anvil part 92 is cancelled | released.

  After the restriction by the movable anvil portion operation restriction mechanism 62 is released, the shaft 64 is inserted into the long hole of the connector body 63 when the penetration amount of the punching blade 7 and the cutting blade 8 with respect to the paper P exceeds a certain value. It abuts on one end 636 of 635, that is, the upper end of the long hole 635. That is, at this stage, the punching blade 7 and the cutting blade 8 reach the switching position (L).

  Then, after the movable anvil portion operation restricting mechanism 62 is released and the cutting blade 7 and the cutting blade 8 reach the switching position (L), the blade unit 3 including the cutting blade 7 and the cutting blade 8, and the connector 61 and the movable anvil part 92 move together with respect to the base part 2 in conjunction with each other. More specifically, when the slide member 31 is lifted while keeping the shaft 64 in contact with the upper end of the long hole 635 provided in the connector main body 63, the slide member 31 moves upward. Is transmitted to the connector 61 via the shaft 64, and the connector 61 moves upward. The movable anvil portion 92 attached to one end portion 633 of the arm portion 631 of the connector 61 via the connect pin 971 is separated from the stationary anvil portion 91 and allows the cut and raised piece P11 to be inserted into the cut hole P2. It is moved upward to a separation position (S) that does not impede this. In this way, until the switching position (L) is reached, the movable anvil portion operation restriction mechanism 62 restricts, and the restriction is released near the switching position (L), and the movable anvil portion 92 is interlocked with the slide member 31. By doing so, the movable anvil part 92 can be reliably moved from the drilling position (C) to the separation position (S) at an appropriate time.

  After the drilling, when the punching blade 7 and the cutting blade 8 are raised and reach the cam rotation start position (R), the inner cam 32 is rotated and the cut and raised piece P11 is moved to the window of the cutting blade 8. The operation of inserting into 85 begins. At that time, the movable anvil portion 92 is raised to the separation position (S) where it does not interfere with the inner cam 32. Specifically, at the cam rotation start position (R), the arm 322 of the inner cam 32 disposed inside the punching blade 7 abuts on the locking portion 332 of the pusher 33. In this state, when the slide member 31 is further raised and the punching blade 7 and the cutting blade 8 reach the upper limit position (U), as shown in FIGS. 17 and 21, the inner cam 32 is rotated (R) ). As a result, the leading end portion P12 side of the cut and raised piece P11 cut and raised from the punching hole P1 to the other side Pb of the paper P is pressed by the pushing portion 323 of the inner cam 32 and inserted into the window 85 of the cutting blade 8. Is done. At this time, the movable anvil portion 92 including the movable opening 95 for the cutting blade and the movable opening 96 for the cutting blade having complicated shapes corresponding to the shapes of the cutting blade 7 and the cutting blade 8 are separated from each other (S). Therefore, the inner cam 32 does not hinder the rotation of the inner cam 32 to the rotation posture (R).

  Next, when the operation on the operation handle 4 is released, the reverse operation of the above-described operation is performed and the initial state is restored. Therefore, when the inner cam 32 returns from the rotational posture (R) to the initial posture (F). The inner cam 32 and the movable anvil portion 92 do not interfere with each other.

  Specifically, when the operation on the operation handle 4 is released, the slide member 31 moves downward due to the repulsive force of the coil springs S1 and S2, and the inner cam 32 starts to return to the initial posture (F). And when the cutting blade 8 descends to the cam rotation start position (R), it returns to the initial posture (F). The urging force for the inner cam 32 to return to the initial position is due to the repulsive force of the coil spring S3 provided on the slide member 31.

  Then, the cutting blade 8 and the cutting blade 7 are extracted from the paper P in a state where the paper P is pressed in the direction of the stationary anvil portion 91 by the paper presser 331 of the pusher 33. More specifically, the punching blade 7 and the cutting blade 8 are moved downward by the repulsive force of the coil springs S1 and S2, and the paper P is being pulled away from the stationary anvil portion 91 of the anvil 9 as shown in FIG. The cutting blade 7 and the cutting blade 8 are extracted from the paper P. At that time, the cut and raised piece P11 inserted in the window 85 of the cutting blade 8 passes through the cut hole P2 and is extracted to the one surface Pa side of the paper P, and the plurality of paper P is fed by this cut and raised piece P11. It is bound. If the paper P is extracted from the binding machine 1 in this state, the booklet B described above is completed. In the case where the extraction blade 7 and the cutting blade 8 cannot be pulled out to the one surface Pa side of the paper P only by the elastic force of the coil springs S1 and S2, the operation handle 4 is operated upward to pull it out. You can help.

  In the middle of the above operation, that is, when the punching blade 7 and the cutting blade 8 are lowered downward beyond the switching position (L), the restriction by the movable anvil part movement restriction mechanism 62 is resumed. That is, the state in which the release member 662 provided on the slide member 31 presses the inclined surface 661 of the locking member 65 ends at a position slightly lower than the switching position (L), and the locking member 65 is twisted by the torsion coil spring S4. The self-reset to the position engaged with the upper end of the connection portion 632 of the connector main body 63 by the urging force.

  In FIG. 21, the retracted position (S), switching position (L), cam rotation start position (R), and upper limit position (U) taking the tip of the blade body 72 of the punching blade 7 as an example on the right side. Although the relationship is shown, the retracted position (S), switching position (L), cam rotation start position (R), and upper limit position (U) of the cutting blade 7 and the cutting blade 8 described above correspond to this. Is.

  As described above, the binding machine 1 according to the present embodiment includes a plurality of sheets P disposed between the anvil 9 and the cutting blade 7 and the cutting blade 8, and the cutting blade 7 and the cutting blade. 8 is moved in the direction of the anvil 9 to penetrate the paper P, and the punching hole P1 and the cut hole P2 are formed in the paper P by the cooperation of the punching blade 7 and the cutting blade 8 and the anvil 9, and the punching hole Since the cut and raised pieces P11 cut and raised from P1 are inserted into the cut holes P2, the paper P can be bound to each other. Therefore, the cut and raised pieces P11 cut and raised from the punched holes P1. A plurality of sheets of paper P are joined together, and the cut and raised pieces P11, which serve as staples, and the paper P are made of the same quality of paper, so there is no need to remove the staples when discarding the paper. Metal needles from P Fine work that support is not required, it is possible to waste without requiring a lot of and a great deal of effort even in the case of discarding the paper P time.

  In particular, the binding machine 1 includes the stationary anvil portion 91 in which the anvil 9 is held at a fixed position, and the punching position (C) where the paper P can be supported by backing in cooperation with the stationary anvil portion 91. A movable anvil portion 92 that is movable away from the stationary anvil portion 91 and can be moved to a separation position (S) that does not obstruct the insertion of the cut and raised piece P11 into the cut hole P2, and the punching blade 7 and The movable anvil portion 92 is held at the punching position (C) until the switching position (L) where the amount of penetration of the cutting blade 8 with respect to the paper P reaches a constant value, and in the region where the amount of penetration exceeds a certain value. Since the anvil part driving means 6 for moving the movable anvil part 92 to the separation position (S) is provided, the stationary anvil part 91 and the movable anvil part 92 cooperate with each other until the switching position (L). Support backing Therefore, the punching blades 7 and cutting blade 8 can be reliably penetrated in a state where the sheet P is sufficiently backed up. At the same time, in the region beyond the switching position (L), the movable anvil portion 92 is moved to the separation position (S), so that interference between the movable anvil portion 92 and other members can be avoided. That is, since the relative position of the movable anvil part 92 with respect to the stationary anvil part 91 can be changed, the opening shape of the anvil 9 can be made an appropriate shape up to the switching position (L), and the switching position ( In the region exceeding L), the opening shape of the anvil 9 can be made to be a shape that does not interfere with the rotation operation of the inner cam 32. In the present embodiment, until the switching position (L), the shape of the opening for the punching blade 7 can be substantially S-shaped, and in the region beyond the switching position (L), the anvil The opening shape can be a large rectangular shape surrounding the S-shaped portion.

  The punching blade 7 used in the binding machine 1 has an inner cam 32 disposed inside the punching blade 7, and a cam in which the penetration amount of the punching blade 7 and the cutting blade 8 with respect to the paper P reaches a predetermined value. Until the rotation start position (R), the inner cam 32 is held in the extraction blade 7, and the inner cam 32 is rotated in a region where the penetration amount exceeds a certain value, so that the cut and raised piece P11 is moved to the cutting blade. 8 is provided with an inner cam rotation mechanism K1 that is inserted into a window 85 provided in FIG. 8, so that the inner cam 32 can be rotated even if the movable anvil portion 92 has a complicated shape corresponding to the shape of the punching blade 7. There is no risk of interference.

  Further, the cutting blade 8 is provided so that a plurality of cut holes P2 can be formed by a single drilling operation, and the punching blade 7 is inserted into the cut holes P2. Since P11 can be formed, the bonding strength can be increased as compared with the case where the bonding portion P3 is provided at only one place. In particular, in the present embodiment, since the leading end portion of the cut and raised piece P11 is bound in the opposite direction, the reliability of the engagement state of the cut and raised piece P11 with respect to the cut hole P2 can be increased. Further, since a plurality of sheets P are bound at the corner P4 of the sheet P, when the user turns the sheet P, a force is applied in the direction of the side of the cut and raised piece P11. Since the direction in which this force is applied is the longitudinal direction of the cut and raised piece P11, that is, the direction perpendicular to the direction extending from the base end portion P13 to the base end portion P12 of the cut and raised piece P11, this engaged state can be maintained. .

  Further, in the present embodiment, the two cutting blades 8 and the two inner cams 32 are arranged with the same shape facing away from each other, so that the number of parts can be reduced.

  The punching blade 7 and the cutting blade 8 are held by the slide member 31 and are provided so as to be able to advance and retract between the drilling position (C) and the retracted position (S). In a region where the punching blade 7 and the cutting blade 8 reach the switching position (L) and the penetration amount exceeds a certain value, the movement of the slide member 31 is transmitted to the movable anvil portion 92 and the movable anvil portion 92 is moved away from the position. A connector 61 to be moved to (S), a movable anvil portion operation restriction mechanism 62 that prohibits the movement of the movable anvil portion 92 in a region until the cutting blade 8 and the cutting blade 7 reach the switching position (L); Therefore, the operation force applied to the operation part 41 of the operation handle 4 to move the slide member 31 up and down can be converted into the movement of the movable anvil part 92.

  The connector 61 includes a connector main body 63 having one end portion 633 pivotally attached to the movable anvil portion 92, and the other end portion 634 provided with a long hole 635 extending in the advancing and retreating direction of the cutting blade 8 and the cutting blade 7. 31 is provided with a shaft 64 engaged with a long hole 635 of the connector main body 63 until the shaft 64 reaches the switching position (L). And is set so as to be in contact with one end 636 of the long hole 635 at the switching position (L), so that it can reach the switching position (L). In the region, the force transmitted to the shaft 64 is not converted into a force for moving the connector 61. On the other hand, after reaching the switching position (L), the force transmitted to the shaft 64 is not connected. 61 is converted into a force that moves the. Therefore, even if the slide member 31 moves by a certain distance, the movable anvil part 92 does not move, and the movement distance of the slide member 31 and the movement distance of the movable anvil part 92 are linked only after reaching the switching position (L). Can do. Therefore, at the moment when the punching blade 7 and the cutting blade 8 are inserted into the paper P, the slide member 31 is raised, and the movable anvil portion 92 is positioned at the punching position (C) in cooperation with the stationary anvil portion 91. By doing so, the paper P can be firmly backed up, and the punching blade 7 and the cutting blade 8 are inserted into the paper P for a certain distance, and the inner cam 32 of the punching blade 7 is rotated from the initial posture (F) to the rotating posture (R). ), The slide member 31 is raised and the inner cam 32 is rotated, and the movable anvil part 92 is moved to the separation position (S) separated upward from the stationary anvil part 91 to thereby move the inner member. It is possible to prevent the rotating operation of the cam 32 from being obstructed by the movable anvil portion 92, specifically, the anvil body 93 and the anvil case 94. Therefore, the paper P can be bound smoothly.

  The movable anvil portion operation restricting mechanism 62 engages with the connector 61 in a region until the cutting blade 8 and the punching blade 7 reach the switching position (L) and inhibits the movement of the connector 61. And an engagement release portion 66 for releasing the engagement of the locking member 65 with respect to the connector 61 in a region beyond the switching position (L). If the locked state is released, the connector main body 63 can be moved via the shaft 64 engaged with the elongated hole 635 of the connector main body 63. In particular, in the present embodiment, the locking member 65 has the claw portion 651 biased by the torsion coil spring S4. Therefore, when the connector 61 returns to the initial state, the torsion coil spring S4. By the urging, the claw portion 651 is engaged with the connector 61, and the original locking state can be restored.

  Further, when the user performs a series of operations such as pressing and releasing the operation handle 4 provided in the binding machine 1, a punching hole P1 for a plurality of sheets P is formed and cut out from the punching hole P1. A booklet B in which the plurality of sheets P are joined to each other can be made using the raised and raised pieces P11.

  Moreover, since the stationary anvil part 92 is fixed to the base part 2, the rigidity of the binding machine 1 as a whole can be increased, and a stable operation can be performed.

  The cutting blade 8 is formed by bending the first sub-blade 83 and the second sub-blade 84 with the both sides of the window 85 as a boundary, so that the size of the main slit L and the paper P The total width dimension of the two cut and raised pieces P11 punched out from can be set to substantially the same dimension. Even when the paper P is relatively thick or the number of the paper P is large, the portion surrounded by the main slit L and the sub slits L1 and L2 is the paper P when the cutting blade 8 is pulled out. Therefore, the operation handle 4 can be pulled up with a lighter operating force. That is, it is not necessary to make the coil spring S1 that gives a repulsive force to the operation handle 4 so strong.

  Furthermore, since this punching blade 7 has the blade main body 73 not only on the tip side but also on the side end side, the shape of the punching hole P1 can be made beautiful. That is, since the blade body 73 on the side end side of the punching blade 7 is provided along the punching direction of the paper P, the punching hole P1 formed by such a punching blade 7 is the blade on the side end side. Compared with a punched hole formed by a punching blade that does not have a main body, the end of the punched hole P1 can be formed more precisely. Therefore, when the inner cam 32 presses the cut and raised piece P11, the occurrence of the problem that the cut and raised piece P11 becomes unnecessarily long so as not to pass through the window 85 of the cutting blade 8 is effectively suppressed or It is possible to prevent or prevent the base end portion P13 of the cut and raised piece P11 from being broken and torn from the base end portion P13 of the punching hole P1.

  The present invention is not limited to the embodiment described above.

  The shapes of the punching hole, the punching blade corresponding to this, the movable opening for punching blades, and the stationary opening for punching blades are not limited to those described above. For example, the tip of the cut and raised piece may be arcuate, triangular, or the shape of an arrowhead, etc., and a cutting blade for forming such a cut and raised piece, A movable opening for a punching blade and a stationary opening for a punching blade may be used. An example is shown in FIG. 23 and FIG. Hereinafter, the components corresponding to the above-described embodiment are denoted by the same reference numerals with “A” at the head, and detailed description thereof is omitted.

  The punching blade A7 shown in FIGS. 23 and 24 has an S-shape corresponding to the shape of the punching blade A7 immediately after drilling by the punching blade A7, and is substantially rectangular after the cut and raised piece AP11 is cut and raised. It is for forming the hole AP1, and is shown in a perspective view in FIG. 23 and in a plan view in FIG. This punching blade A7 is formed by bending a single sheet metal material, and the blade body A72 provided at the tip thereof is continuous in an S-shape in a plan view that is smoother than in the above-described embodiment. It has a cutting edge. This blade body A72 is provided with a blade tip end portion A721 that first penetrates the paper AP at one central portion. The blade body A72 has a double-edged structure having a blade edge in the center of the thickness direction of the material.

  As the anvil A9 used together with the punching blade A7, a stationary anvil portion A91 schematically shown in FIG. 24 and a movable opening for the punching blade arranged corresponding to the stationary opening portion A911 for the punching blade of the stationary anvil portion A91. It is preferable to use one provided with a movable anvil part A92 provided with a part A95.

  Moreover, the shape of the cut hole, the corresponding cutting blade, the movable opening for the cutting blade, and the stationary opening for the cutting blade is not limited to that described above. For example, a straight line having only a main slit or a curved line, a substantially U-shaped one having sub-slits extending in only one direction from both ends of the main slit, and substantially H shown in the present embodiment. Various modifications such as those in which the angle formed between the main slit and the sub slit is other than 90 degrees can be used as modified examples of the cut hole having a letter shape. In particular, in the present embodiment, the shape of the movable opening for the cutting blade provided in the movable anvil portion is made rectangular with respect to the substantially H-shaped cut hole. The shape of the opening may be an H shape corresponding to the cut hole. If the shape of the cutting blade movable opening is H-shaped, when the cut hole is punched by the cooperation of the cutting blade and the cutting blade movable opening, The backing can be supported, and the shape of the cut hole can be formed neatly.

  Furthermore, in the present embodiment, the anvil portion driving means is configured to move the movable anvil portion using the handle operation, but may be driven using an operation force other than the handle operation.

  Further, the anvil portion driving means holds the movable anvil portion at the punching position until the switching position as described above, and moves the movable anvil portion to the separation position in a region where the penetration amount exceeds a certain value. It is not limited to things. That is, the anvil is separated from the stationary anvil portion from a stationary anvil portion that is held at a fixed position, and a punching position capable of backing and supporting paper in cooperation with the stationary anvil portion, and the cut and raised pieces are cut. If it is provided with a movable anvil part that can move to a separated position that does not impede insertion through the hole, it is suitable for a binding machine that can sufficiently secure the backing of the paper during punching as described above. In addition, the moving timing and moving range of the movable anvil portion can be designed to be most suitable for forming the punched hole and the cut hole. Therefore, as compared with the conventional one in which the anvil is composed only of the stationary anvil portion, the degree of design freedom can be increased, and more demands can be met.

  Further, the positions where the punched holes and the cut holes are provided in the paper are not limited to the corners, but may be positions along the sides of the paper. Further, the number of punched holes and cut holes is not limited to one for the booklet, and may include a plurality of punched holes and cut holes, but only one punched hole as shown in the present embodiment is provided. In this case, it is particularly effective because a lateral shift is likely to occur. When forming a plurality of punch holes and cut holes, for example, if two punch holes are formed corresponding to the pitch of the binding rod of a binding tool such as a file, the punch hole is formed into a file having two binding rods. It can be used as a binding hole for binding a booklet. Further, the size and shape of the punched hole and the cut hole can be variously changed.

  As long as the paper is in sheet form, various changes such as paper or plastic can be made. In addition, if a plurality of sheet bodies made of the same quality material are bound, it is possible to reduce the trouble in sorting and discarding.

  The blade unit may have not only a three-piece structure of a cutting blade, a cutting blade and an inner cam, but also a two-piece structure of a cutting blade and a cutting blade. At this time, it is preferable that the punching blade is provided so as to be rotatable between a punching posture and a rotating posture, and a punching hole can be formed in the punching posture. That is, the punching mechanism allows the punching blade to penetrate the paper disposed on the lower surface side of the anvil from one side, and the punching blade penetrating the paper is rotated to the rotating position to rotate the punching hole to the other side. What is necessary is just to provide the blade extraction mechanism which makes the cutting blade holding the cutting and raising piece cut and raised to the one surface side of the paper together with the cutting and raising piece.

  Further, the projecting and retracting direction of the slide member is not limited to the up and down direction shown in the present embodiment. For example, the projecting side of the punching blade and the cutting blade is set to the lower side, and the immersion side is set to the upper side. It is also possible.

  In addition, various changes may be made without departing from the spirit of the present invention.
