Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutting blade of a binding machine that does not use a metal needle among binding machines that integrally bind the ends of a plurality of stacked sheets.

  Conventionally, various types of binding machines that do not use metal needles have been considered. As an example of such a binding machine, for example, a cut hole is punched in a plurality of sheets, an adhesive tape coated with an adhesive is inserted into the cut hole, and the ends of the adhesive tape are bonded with an adhesive. By fixing, a plurality of sheets can be bound so as to form a closed loop passing through the outer edges of the plurality of sheets and the cut holes (see, for example, Patent Document 1).

  That is, the binding machine described in Patent Document 1 uses an adhesive tape in which an adhesive is applied to at least a part of one surface as a binding member that passes through a cut hole for binding a plurality of sheets. And this adhesive tape is hold | maintained so that peeling is possible in the state which followed the predetermined dimension for the strip | belt-shaped separation tape by which the peeling process was given to the surface, for example.

  As another example of a binding machine that does not use a metal needle, a punching blade that forms a punching hole while forming cut and raised pieces on a plurality of sheets of paper, and provided adjacent to the punching blade, A cutting blade for forming a cut hole for locking the leading end side of the cut and raised piece, a binding machine main body for holding the punching blade and the cutting blade, and a paper insertion gap in the binding machine main body And a stage provided with a stage (see, for example, Patent Document 2).

  That is, in the binding machine described in Patent Document 2, a binding member that passes through a cut hole to bind a plurality of sheets is a cut and raised piece that is a part of the same sheet.

  By the way, in each of the above binding machines, the cutting blade is provided with a binding member insertion window that can be engaged with the binding member, and the binding member is engaged with the binding member insertion window. In the combined state, when performing the operation of extracting the cutting blade from the cut hole, the cut and raised pieces are inserted through the cut hole.

  Here, in the binding machine as described above, in the former case, the adhesive applied to the adhesive tape as the binding member touches the cut edge of the cut hole, or in the latter case, a plurality of sheets. In some cases, the thickness of the cut-and-raised piece as the binding member formed by the above becomes large. At this time, in any case, since a load generated when the binding member is passed through the cut hole and led to the front surface side of the sheet becomes large, a large extraction force may be required. In other words, as described above, a manual operation type binding machine may require a large operating force. In other words, in the manual operation type, the cutting blade is penetrated through the paper against the elastic force of the spring, and the cutting blade is extracted from the paper by the elastic force of the spring. When the load of the motor temporarily increases, a spring having a large repulsive force must be used, and a large force may be required even during manual operation.

  In addition, when using a spring with a large repulsive force, the operating force required when drilling the cut hole is not only the force required for the cutting edge to pass through the paper, A force for operating the cutting blade against the repulsive force is also required.

  The above problems are that the cutting blade has a window with which the binding member can be engaged, and the binding member engaged with this window is inserted into the cut hole during the operation of extracting the cutting blade from the cut hole. It exists in all binding machines that are configured to pass.

  That is, in order to effectively reduce the operation force necessary for using the binding machine, it is necessary to reduce the force required to pass the binding member through the cut hole or to drill the cut hole. There is a need to reduce power.

Japanese Patent No. 3122807 JP 2011-189547 A

  This invention pays attention to such a malfunction, and it aims at providing the cutting blade used for the binding machine which can reduce effectively the operation force required in order to use a binding machine. .

  In order to achieve such an object, the present invention takes the following measures.

  That is, the cutting blade of the binding machine according to the present invention includes a blade body having a blade tip for forming a cut hole in the paper by reciprocating relative to the paper and penetrating the paper, Inserted in the cut hole through the cut hole in a state where the band main body is provided so as to penetrate the blade main body in the thickness direction, and a band-like binding member for binding paper when the blade main body is extracted from the cut hole is engaged. A binding member insertion window, and a cutting edge forming a pair facing the cut hole when the binding member insertion window passes through the cut hole by being raised in the thickness direction from the blade body, thereby separating a gap. And a gap-forming raised portion to be formed.

  In such a case, when the binding member passes through the cut hole, the opposing cutting edges of the cut hole are separated from each other, in other words, the cut hole is in an expanded state so that the binding member is cut. It becomes possible to avoid effectively interfering with. That is, according to this invention, the cutting blade used for the binding machine which can reduce effectively the operation force required in order to use a binding machine can be provided.

  And as a structure which can expand a cut hole effectively, the structure by which the protruding part is formed in the width direction both sides of the binding member penetration window can be mentioned.

  Further, as a configuration capable of effectively expanding the cut hole at the timing when the binding member passes through the paper, a configuration in which the raised portion is provided at least partially on the base end side with respect to the front end edge of the binding member insertion window. Can be mentioned.

  In particular, the timing at which the binding member is most likely to interfere with the cut hole is the timing at which the binding member passes through the cut hole while being lifted by the leading edge of the binding member insertion window, and effectively avoids the interference of the binding member with the cut hole. In order to achieve this, it is desirable to have a configuration in which the raised portion extends to the tip side from the binding member insertion window.

In order to greatly expand the cut hole without damaging the cut hole itself, the raised portion has an inclined surface provided to be inclined from the most raised raised end toward the edge in the width direction of the blade body.

As a configuration capable of effectively expanding the cut hole, the raised portions are formed on both the back surface side facing the binding source side of the paper and the front surface side facing the binding destination side of the paper in the blade body.

Blade body, and Na sectional shape curved so as to form a cut hole which bulges toward the binding tip side of the paper. Since the cut edge of the cut hole on the lower side of the bulge is turned up and down by the raised portion, the cut hole can be expanded more effectively.

<Thickness structure of the blade edge>
Further, in order to solve the same problem as that of the present invention, the following means can be taken separately. That is, the cutting blade of the binding machine according to the present invention has the following configuration.

The blade edge has a shape in which the width and thickness are gradually increased from the tip toward the base, and a narrow region having a width smaller than the width of the cut hole and a thin region in which the thickness gradually changes. A cutting blade for a binding machine, characterized in that the thin region includes the narrow region.

  If it is such, the increase of the cross-sectional area of the location where a blade edge | tip passes a paper can be made slower than before. As a result, the cut hole can be drilled with a small operating force. That is, according to this invention, the cutting blade used for the binding machine which can reduce effectively the operation force required in order to use a binding machine can be provided.

  (2) A gap-forming raised portion that forms a gap by separating a pair of cut edges that form opposed pairs of the cut holes by protruding in the thickness direction from the blade body on the base end side with respect to the thin region. The cutting blade of the binding machine according to (1), which has

As a result, a gap is formed between the blade body and the cutting edge of the cut hole, so that the portion in contact with the paper when the cutting blade passes can be made small and the cutting blade can be operated with a small force. .
(3) The cutting blade of the binding machine according to (1) or (2), wherein the raised portion has a tapered surface that increases the raised dimension from the distal end edge to the proximal end side of the raised portion.

Thereby, it can contribute to the smooth drilling operation | movement of a cutting blade.

(7) The cutting blade of the binding machine according to (6), wherein a lower end edge of the binding member insertion window is curved along a cross-sectional shape of the blade body.

  If the thin blade body is used, the edge of the binding member insertion window is naturally made thin, and there may be a problem that the acting force is locally concentrated on the binding member and bent. However, with the above-described configuration, when the binding member is pulled up, it can be pulled up with a large dimension in the thickness direction. As a result, it is possible to avoid the occurrence of creases and damage to the binding member due to local concentration of force on the binding member, and to prevent the binding member from being damaged or undesirably broken.

Is possible.

  The front tape guide 17f corresponds to a binding tip side guide that guides the adhesive tape 81 in front of the cutting blade 3, that is, on the binding tip side. The front tape guide 17f is pressed before the paper P is placed on the stage 9 and during the operation of placing the paper P on the stage 9, and the pressure-sensitive adhesive tape 81 inserted through the cut hole P1 is pressed by the compression roller 17b. Even at the previous timing, the adhesive tape 81 can be guided in the width direction. The front tape guide 17f is a lateral guide 17f1 that can guide the side end of the adhesive tape 81, and a lower end of a curved portion that is spaced upward from the side view stage 9 between the lateral guides 17f1. And a lower end guide 17f2 positioned slightly above the lateral guide 17f1. In this embodiment, the lower end of the lower end guide 17f2 is positioned further to the front end side than the front end of the cutting blade 3 before the binding operation.

  With the configuration of the binding mechanism 1 described above, when the handle 12 is moved by a user's operation, the sliding shaft portion 14a2 of the first link 14a is moved according to the operation of the handle 12, as shown in FIGS. The lower link is lowered along the twelve link support holes 12b and the lower link lowers the second link 14b.

As a result, the adhesive tape 81 can be peeled off from the separation tape 82 by a length corresponding to a predetermined dimension between the openings 80 and used for the operation of the binding mechanism 1. In the present embodiment, the dimension between the openings 80 and the dimension between the perforations 85 are set so as to be always smaller than the operation distance of the operation tape 8 that can be operated by the operation stroke of the rack member 44.

  Further, in the present embodiment, when the opening 80 is provided, a substantially C-shaped slit 83 s is formed without providing a hole in the spacing tape 82. By forming the slit 83s, an opening 80, which is a recess communicating with the front and back, is formed by contacting a projection 54b, which will be described later, on the stopper member 54 side. In the present embodiment, the shape of the slit 83 s is approximately C-shaped, but any shape may be used as long as a concave portion that penetrates the front and back of the separation tape 82 can be formed in the convex portion by contacting the convex portion.

  In the present embodiment, the perforation 85 is provided at a position separated from the slit 83s. Of course, the position of the perforation 85 is not limited to the position of the opening 80 or the slit 83s.

  Next, the configuration of each part of the refill 5 will be described with reference to FIGS. The reel support plate 51 is configured so that the operation tape 8 and the separation tape 82 and the adhesive tape 81 can be separated from the operation reel receiver 51 a and the take-up reel receiver 51 b for supporting the operation reel 52 and the take-up reel 53. A supporting separation inducing portion 51c, a stopper fixing portion 51d for fixing the stopper member 54, an operation side sag preventing claw 51e that engages with the operation reel 52 to prevent the operation reel 52 from sagging, and winding It has a winding side reverse rotation preventing claw 51f that allows only rotation in the winding direction of the reel 53, and a plurality of tape guide shafts 51g. The separation inducing portion 51c is for urging the adhesive tape 81 from being separated from the separation tape 82 by folding and supporting the operation tape 8. In this embodiment, by positioning the separation inducing portion 51c in the vicinity of one end edge of the reel support plate 51, the tip of the adhesive tape 81 partially separated from the separation tape 82 by the separation inducing portion 51c passes through the stage 9 and the front tape. The guide 17f is positioned at a predetermined position. In this embodiment, the reel support plate 51 is provided with a plurality of tape guide shafts 51g for guiding the operating tape 8 to a required path as shown in FIG. The tape guide shaft 51g can be provided at an appropriate location according to the setting of the path of the operating tape 8.

  The operation reel 52 has an operation side sag prevention surface 52e that engages with the operation side sag prevention claw 51e of the reel support plate 51 in order to prevent the operation tape 8 from sagging while the operation tape 8 is wound and held. ing.

  The take-up reel 53 winds and holds the operating tape 8 after passing through the separation inducing portion 51c, and the winding side of the reel support plate 51 in order to inhibit the separation tape 82 from rotating in the direction opposite to the take-up direction. It has a winding side reverse rotation prevention surface 53f that engages with the reverse rotation prevention claw 51f. That is, the take-up reel 53 and the reel support plate 51 constitute a reverse rotation prevention mechanism that can prohibit the rotation related to the operation of the separation tape 82 in the opposite direction. In this embodiment, the take-up reel 53 serves as a tape operating unit that operates the operating tape 8 by an operating force applied to the operating lever 42 that constitutes the operating unit. In addition, the take-up reel 53 plays a role as a separation tape accommodating portion that can accommodate the separation tape 82 fed together with the reel support plate 51 through the separation inducing portion 51c in the case.

  The stopper member 54 is for engaging the opening 80, which is a recess provided in the operating tape 8, during the operation of the operating tape 8, and accurately stopping the operation of the operating tape 8 when the operation of the operating tape 8 is performed by a predetermined dimension. The stopper member 54 includes an operating shaft 54a that is rotatably supported at one end side at a position where the separation inducing portion 51c is provided, and an operating tape 8 that extends along the operating tape 8 from the operating shaft 54a.

<Operation description of tape feeding mechanism>
By the tape delivery mechanism 2 described above, a part of the adhesive tape 81, which is a binding member on which the refill 5 is wound and held, is accurately delivered to a predetermined position located in the vicinity of the front tape guide 17f partly beyond the stage 9. be able to. Hereinafter, the operation of the tape delivery mechanism 2 will be described with reference to FIGS.

  7 and 8 show operations of the operation lever 42, the curved link 43, the rack member 44, and the pinion member 45 constituting the operation unit in the lower unit 4. FIG. As shown in the figure, when the operation lever 42 is pressed with a finger or the like, the rack link 44 is pushed downward by operating the curved link 43. At this time, the pinion member 45 rotates when the rack member 44 operates in a state where the rack teeth 44 a of the rack member 44 are engaged with the pinion teeth 45 a of the pinion member 45. Further, when the rack teeth 44a and the pinion teeth 45a are engaged with each other, the retrograde prevention protrusions 44c of the rack member 44 are in contact with the retrograde prevention teeth 41c of the lower case 41 and the retrograde prevention teeth 48c of the rack cover 48, respectively. Yes. Therefore, if the operating force is released in the state shown in the figure, the operation start is biased by the action of the expansion and contraction spring 47. At this time, the anti-reverse teeth 41c, 48c and the anti-reverse protrusion 44c are engaged, and the rack member 44 is Stop in the state shown in the figure. FIG. 8 shows a state in which the rack member 44 is at or near the operation end. At this time, the anti-reverse protrusion 44c is separated from the anti-reverse teeth 41c and 48c. Therefore, when the operation force is released, the operation lever 42 curved link 43 and the rack member 44 are moved toward the operation start end by the action of the expansion spring 47. Works. That is, in the present embodiment, the rack member 44 is in an intermediate position until the end of operation by the retrograde prevention protrusions 44c of the rack member 44 and the retrograde prevention teeth 41c and 48c provided on the lower case 41 and the rack cover 48, respectively. In some cases, a return prevention mechanism for prohibiting the return operation to the operation start end is configured.

  12 and 13 show the positions of the rack member 44 and the refill 5 at the operation start end of the operation lever 42 and in the vicinity thereof. For convenience of explanation, only the stopper member 54 and the stopper receiver 55 of the refill 5 are shown in FIG. In FIG. 13, the separation tape 82 in a state in which the opening 80 formed by the slit 83 s is inserted into the protrusion 54 b of the stopper member 54 is indicated by an imaginary line, and a part of the stopper member 54 and the stopper receiver 55 are shown in cross section. Show. When the operation lever 42 is operated, the lock release surface 44f of the rack member 44 first presses the lock release portion 54d provided on the stopper member 54 of the refill 5, so that the projection 54b is opposed to the elastic biasing portion 54c. Retract from the stopper receiver 55. At this time, the protrusion 54b quickly retracts from the protrusion receiving hole 55a. However, as the rack member 44 continues to operate, the unlocking surface 44f moves away from the unlocking portion 54d, and the return taper 44g is quickly positioned at the position of the unlocking portion 54d. As a result, the unlocking portion 54d is retracted from the opening 80 at one end by the operation of the rack member 44, but before the separation tape 82 further operates and the next slit 83s reaches the position of the unlocking portion 54d. The protrusion 54b is again urged by the elastic urging portion 54c. Specifically, the protrusion 54b retracted from the one-end opening 80 continues to urge the back surface of the spacing tape 82 until the next slit 83s comes. That is, in this embodiment, the operation force is transmitted to the take-up reel 53, which is the tape operating portion, by the operation force before the force is transmitted to the take-up reel 53, which is the tape operation unit, by the lock release surface 44f of the rack member 44, the return taper 44g and the lock release portion 54d. A starting-time release portion that releases the engaged state between the protrusion 54b and the opening 80 is configured.

  14 to 19 schematically show a series of operations of the rack member 44 operated by being guided by the rail 41b, and operations of the pinion member 45 and the clutch 46. FIG. 14 shows a state in which the rack member 44 is at the operation start end. In such a state, the rack teeth 44a are separated from the pinion teeth 45a.

  Then, when the operating force is applied from the state shown in FIG. 14, the rack member 44 moves obliquely downward in the drawing as shown in FIG. 15, and the engagement guide surface 44d1 of the guided projection 44d is the guide projection 41b2. Engagement of the rack teeth 44a and the pinion teeth 45a starts by hitting the engagement guide surface 41b3. Further, at the timing shown in FIG. 15, the unlocking portion 54d provided on the stopper member 54 of the refill 5 is pressed against the unlocking surface 44f, and the operation of the separation tape 82 is permitted.

  When further operating force is applied from the state shown in FIG. 15, the guided projection 44d is guided along the engagement maintaining surface 41b4 of the rail 41b, so that the rack teeth 44a move linearly in the tangential direction of the pinion teeth 45a. As a result, the pinion member 45 rotates, and the clutch 46 rotates together with the take-up reel 53 in accordance with the rotation.

  Here, the dimension at which the separation tape 82 can be sent out by one operation of the operation lever 42 is the length dimension of the adhesive tape 81 even when the separation tape 82 is not wound around the take-up reel 53 and the diameter is the smallest. It is set larger than the dimension between the openings 80. That is, as shown in FIG. 16, at any timing when the pinion member 45 rotates while the rack teeth 44a and the pinion teeth 45a mesh with each other, the protrusion 54b of the stopper member 54 is in the process of being formed on the separation tape 82 during the feeding operation. It is inserted into the opening 80 by the elastic biasing force of the elastic biasing portion 54c, and the operation of the separation tape 82 and the operation of the take-up reel 53 are prohibited.

  In other words, the operation of the take-up reel 53 is prohibited during the rotation of the pinion member 45 as shown in FIG. Then, as shown in FIG. 17, although the clutch 46 supporting the take-up reel 53 is prohibited from rotating, the pinion member 45 that is in contact with the sliding surface 46b slides and continues to rotate. That is, if the separation tape 82 is fed out by a predetermined dimension, the pinion member 45 is idled appropriately by the action of making the clutch 46 slip. As a result, by operating the operation lever 42, the separation tape 82 is accurately fed out by a predetermined dimension set by the arrangement of the slits 83s. In other words, in this embodiment, the clutch 46 is operated by the separating tape 82, which is the operating tape 8, when the operation force continuously applied after the elastic biasing portion 54c is brought into the engaged state in which the protrusion 54b and the opening 80 are engaged. It plays the role of a transmission prohibition unit that prohibits conversion.

  FIG. 17 shows the rack member 44 at the operation end. Here, when the operating force is released, the rack teeth 44a and the pinion teeth 45a are separated while the separation guide surface 44d2 of the guided projection 44d is in contact with the separation guide surface 41b5 of the guide projection 41b2. That is, the separation guide surface 44d2 of the guided protrusion 44d and the separation guide surface 41b5 of the rail 41b are separated by a separation mechanism that separates the rack member 44 and the pinion member 45 during a return operation caused by the biasing of the expansion spring 47 that is a return member. Is configured.

  Thereafter, as shown in FIGS. 18 and 19, the guided projection 44d performs a return operation along the separation maintaining surface 41b6. At this time, the anti-reverse protrusion 44c is disengaged from the anti-reverse teeth 41c and 48c, so that the rack member 44 is smoothly urged and positioned by the expansion and contraction spring 47 to the operation start end.

<Operation description of the binding mechanism>
Next, an operation in which the binding mechanism 1 binds a plurality of sheets P using the adhesive tape 81 which is the binding member sent out as described above will be described with reference to FIGS. 20 to 24 are perspective views showing the main parts of the binding mechanism 1 and the operation tape 8. 25 to 30 are central right sectional views showing the main part of the binding mechanism 1 and the adhesive tape 81.

  20 and 25 show a state before the paper P to be bound with the adhesive tape 81 positioned at a predetermined position is inserted. At this time, the upper end side of the adhesive tape 81 is guided from the rear by the front tape guide 17f, and it is effectively avoided that it contacts the cutting blade 3.

  When the paper P is inserted toward the set position (st) as shown in FIGS. 21 and 26, the adhesive tape 81 is inserted into the front tape guide 17f and the rear tape guide 16d as shown in FIG. While being guided in the width direction, the adhesive tape 81 operates while simultaneously contacting the lower end guide 17f2 of the front tape guide 17f, the pressing surface 16b1 of the paper presser 16b, and the rear tape guide 16d. Since the lower end guide 17f2 and the pressing surface 16b1 of the paper pressing member 16b are positioned below the forefront of the cutting edge 31, the cutting blade 3 does not touch the adhesive tape 81. Then, when the paper P is moved from the state shown in FIG. 21 to the set position (st) shown in FIG. 22, the adhesive tape 81 is fixed to the paper P so as to wind the binding source side. At the same time, the edge portion P4 on the binding source P3 side of the paper P starts to contact the paper guide 15. In other words, the edge P4 of the sheet P on the binding source P3 side contacts the expansion operation guide surface 15a1 of the guide member 15a in the standby posture (Q2), whereby the rotation operation of the guide member 15a is started. During the rotating operation, the guide member 15a continues the expanding operation while the expanding operation guiding surface 15a1 changes the contact position with the paper P.

  22 and 27 show the time when the cutting blade 3 is lowered by operating the handle 12. FIG. At this time, the lower end side of the adhesive tape 81 passes through the binding member insertion window 32. At this time, since the guide member 15a does not exist on the lower side of the concave surface 16b5, the paper presser 16b continues to descend until it comes into contact with the paper P along with the operation of the blade support portion 16a1. At this time, when the paper presser 16b comes close to the surface of the paper P, the guide body 16d1 of the rear tape guide 16d contacts the paper P prior to the press surface 16b1 and is accommodated in the slit 16b4 against the reaction force spring 16c. The entire pressing surface 16b1 presses the paper P. At this time, as shown particularly in FIG. 27, a cut hole P1 is formed in the paper P through which the blade edge 31 is inserted, and the cut hole P1 is cut at the raised portion 33 provided in the cutting blade 3 at the cutting edge. P2 is expanded and a gap s is formed.

  As shown in FIG. 28, when the cutting blade 3 is raised, the adhesive tape 81 passes through the gap s formed by the expansion, so that the coated adhesive 84 is almost at the cutting edge P2. As shown in FIGS. 23 and 29, the cut hole P1 passes from below to above without touching.

  As shown in FIGS. 30 and 24, when the paper P is moved forward from the set position (st), the adhesive tape 81 that has passed through the cut hole P1 from below to the top is guided to the lateral guide 17f1 of the front tape guide 17f. In addition, it is compressed by the compression roller 17b while being in contact with the lower end guide 17f2 and being prevented from shifting in the lateral direction. Thereby, the closed loop by the adhesive tape 81 is formed in the state which penetrated the edge P4 by the side of the cut hole P1 and the binding origin P3. That is, at this time, the plurality of sheets P are bound by the adhesive tape 81 as a binding member. The guide member 15a only needs to be in a standby posture (Q2) by an elastic member (not shown), and the paper guide 15 separated from the paper P takes the standby posture (Q2) again.

  Through the series of binding operations so far, in the present embodiment, the handle 12, the paper guide 15, and the front and rear tape guides 17f and 16d are configured to operate independently. However, of course, this embodiment does not prevent the configuration in which the operations of these components are linked or the operation posture of any component affects the operations of other components.

<Explanation of cutting blade action>
In addition, in this embodiment, in order to perform the above-described binding operation smoothly, the cutting edge 31 gradually increases in width dimension and thickness from the distal end toward the proximal end as shown in FIGS. 5, 6, and 31 to 35. The shape is designed to increase the size. The cutting edge 31 has a narrow area 31a having a width dimension smaller than the width dimension of the cut hole P1 and a thin area 31b in which the thickness dimension gradually changes, and the patterns are shown in FIGS. The thinned region 31b shown here is shaped to include the narrow region 31a. Accordingly, as shown in FIGS. 32 to 35, the thickness dimension other than the blade edge 31 in the blade body 30 before the width dimension for forming the cut hole P <b> 1 reaches the width dimension of the cut hole P <b> 1 in a cross-sectional view passing through the paper P. The thickness of the part is never reached. As a result, the process of lowering the cutting blade 3 can contribute to the formation of the cut hole P1 by the smooth lowering of the cutting blade 3 without passing through a timing at which an operating force is suddenly required. In addition, after the cut hole P1 is formed, the raised portion 33 gradually expands the cut edge P2 of the cut hole P1 while passing through the taper surface 33b, whereby the cutting blade 3 after the cut hole P1 is formed. By reducing the area in contact with the cut hole P1 and reducing the friction between the cutting edge P2 and the cutting blade 3, it can contribute to the binding operation with a small operating force.

  In this embodiment, the adhesive tape 81 as a binding member passes through the gap s formed by providing the raised portion 33 so that the binding operation by the binding mechanism 1 can be performed smoothly. In addition, in this embodiment, both side edges 36 of the cutting blade 3 are further provided with a polishing surface 36a having a tapered shape, and the side edges 36 themselves can cut the paper P. This makes it difficult for the cutting blade 3 to be caught on the paper P at the side edge 36 during the vertical movement of the cutting blade 3. That is, the side edge 36 effectively reduces friction between the cutting blade 3 that performs the up and down operation and the paper P.

  Also, as shown in FIG. 36, in this embodiment, the shape of the cut hole P1 is formed so as to bulge toward the binding source side, so that the cut hole is handled by handling the paper P on the binding destination side after binding. The force applied to P1 and the adhesive tape 81 can be effectively dispersed, and the state where the paper P is bound can be stably maintained. Further, in the case of the cut hole P1 as shown in the figure, the cut edge P2 formed on the binding tip side has a bulging shape, so that when the raised portion 33 passes, it is easily turned up and down.

  By setting it as the above structures, the cutting blade 3 which concerns on this embodiment WHEREIN: When the adhesive tape 81 which is the adhesive tape 81 penetrates the cut hole P1, the cutting edge P2 which the cut hole P1 opposes spaced apart In other words, the cut hole P1 is expanded. Thereby, it can be effectively avoided that the adhesive tape 81 interferes with the cut hole P1 when passing the paper. That is, according to the present embodiment, by effectively suppressing the friction between the adhesive tape 81 and the cut hole P1 during the binding operation, it is possible to effectively reduce the operation force necessary for using the binding machine. Yes.

  In the present embodiment, a configuration in which the raised portions 33 are formed on both sides in the width direction of the binding member insertion window 32 is applied as a configuration capable of effectively expanding the cut hole P1.

  Further, in the present embodiment, the adhesive tape 81 is actually cut hole so that the raised portion 33 is provided at least partially on the base end edge 32a side with respect to the front end edge 32b of the binding member insertion window 32. The cut hole P1 is expanded in accordance with the timing of passing through.

  In addition, in this embodiment, the protruding portion 33 is provided so as to extend from the proximal end edge 32a side to the distal end side 32b rather than the distal end edge 32b of the binding member insertion window 32 to the distal end side. The cut edge P2 is effectively pressed in accordance with the timing at which the tape 81 passes, and the cut hole P1 is suitably expanded.

  Further, in this embodiment, the bulging portion 33 is provided so as to be inclined in plan view from the most raised bulging end toward the edge in the width direction of the blade body 30 in order to greatly expand the cut hole P1 itself without damaging it. An inclined surface 33a is provided.

  Furthermore, in order to make the cut hole P1 to be effectively expanded and allow the adhesive tape 81 to pass more easily, in this embodiment, the raised portions 33 are formed on both the back surface 30b side and the front surface 30a side of the blade body 30. The configuration is applied.

  In particular, in the present embodiment, the blade body 30 has a curved cross-sectional shape so as to form a cut hole P1 that bulges toward the binding destination side of the paper P. Therefore, the blade body 30 bulges in the cut hole P1. Since the cut edge P2 on the side is easily turned up and down by the raised portion 33, the cut hole P1 can be expanded more effectively. Of course, a cutting blade having a linear shape in plan view may be applied to form the linear cut hole P1.

<Thickness structure of the blade edge>
Here, the cutting blade 3 used in the binding machine according to the present embodiment has a cutting edge 31 for forming a cut hole P1 in the paper P by reciprocating relative to the paper P and penetrating the paper P. A blade body 30 provided at the tip of the blade body 30 is provided so as to penetrate through the blade body 30 in the thickness direction, and an adhesive tape 81 for binding the paper P when the blade body 30 is extracted from the cut hole P1 is engaged. The binding member insertion window 32 for inserting the adhesive tape 81 into the cut hole P1 in the state, the cutting blade 3 of the binding machine, the cutting edge 31 gradually from the distal end toward the proximal end side It has a shape that increases the width dimension and the thickness dimension, and has a narrow area 31a that has a width dimension smaller than the width dimension of the cut hole P1 and a thin area 31b that gradually changes in thickness dimension. The thin area 31b is narrow. Includes region 31a It is characterized in.

  By setting it as the above structures, the cutting blade 3 of the binding machine which concerns on this embodiment can make the cross-sectional area of the location where the blade edge | tip 31 passes the paper P increase more slowly than before. As a result, the cut hole P1 can be drilled with a small operating force. That is, according to this invention, the cutting blade 3 used for the binding machine which can reduce effectively the operation force required in order to use a binding machine is implement | achieved.

  In the present embodiment, in order to make the cutting blade operate with a small force by reducing the portion that comes into contact with the paper when the cutting blade 3 passes, in the present embodiment, it protrudes from the blade body 30 in the thickness direction on the proximal side from the thin region 31b. Thus, the gap forming bulge 33 is formed to form the gap s by separating the cut end edges P2 that form the opposing pairs of the cut holes P1. That is, with such a configuration, the gap s is formed between the blade body 30 and the cutting edge P2 of the cut hole P1, so that friction between the cutting blade 3 and the paper P during operation can be reduced.

  And in order to implement | achieve the smooth drilling operation | movement of the cutting blade 3, in this embodiment, the protruding part 33 had the taper surface 33b which enlarges a protruding dimension from the front end edge of the said protruding part 33 toward a base end side. The configuration is applied.

  In particular, in the present embodiment, the tip edge of the tapered surface 33b and the base edge of the thin region 31b are made continuous so as to realize a smooth operation of the cutting blade 3 through the entire punching operation of the cut hole P1. The cutting blade 3 is applied.

  Further, in order to further reduce the friction during drilling by further reducing the contact between the cutting edge P2 and the cutting blade 3, in this embodiment, the raised portion 33 is provided on both the back surface 30b and the front surface 30a of the blade body 30. To be formed.

  In this embodiment, the blade body 30 has a curved cross-sectional shape so that the curved cut hole P1 can be formed. Even if it reduces, the intensity | strength of the cutting blade 3 itself is effectively securable by raising the bending rigidity of the blade main body 30. FIG. Of course, a cutting blade having a linear shape in plan view may be applied to form the linear cut hole P1.

  In addition, in the present embodiment, the lower end edge of the binding member insertion window 32 is curved along the cross-sectional shape of the blade body 30.

  The binding machine according to this embodiment having the above-described cutting blade 3 includes the cutting blade 3 and a stage 9 that holds the paper P, and the paper P held by the stage 9 has a cutting blade. 3 is a binding machine configured to bind the paper P with the adhesive tape 81 by pulling out the paper 3 and pulling it out.
