[0010] Thereby, at the first position, the staple positioned at the leading portion of the connected staple is cut by the connecting portion cutting blade and separated from the connecting stable, and from the left and right of the crown portion and the crown portion by the molding portion. It is molded so as to form legs that are bent at a substantially right angle. Further, the stable formed into a shape bent in the direction of the force at both ends is pushed down to the binding paper together with the insertion cutting blade by the penetrating portion at the second position and penetrates the binding paper.

[0011] The legs of the stable that have penetrated the binding sheet by the penetrating part pushed down by the pushing-down means are bent by the bending means and bonded to each other. Furthermore, the stable molded by the molding unit is moved from the first position to the second position by the moving means.

[0012] The stapler of the present invention pushes down the connecting portion cutting blade and the forming portion with respect to the staple located at the leading portion of the connected staple by the pressing means to cut and form the staple, and penetrates the binding paper. Push down the part to penetrate the stable. This makes it possible to cut and mold the stable and penetrate the staples into the binding paper by one operation.

[0013] Further, the stapler according to the present invention is cut by a cutting means that cuts a stable positioned at the head of a connecting stable in which a plurality of substantially straight paper stables are connected in parallel, and a cutting means.

[0014] The stapler described above includes a moving unit that moves the stable formed by the forming unit to a penetrating position through which the staple is penetrated by the binding unit.

[0015] Further, a transport path for transporting the connected stable and transport means for transporting the connected stable on the transport path are provided. [0016] In the stapler provided with the conveyance path described above, a peeling means for peeling the release paper attached to the back of each stable of the connection stable from the back of each of the stable at the start end of the conveyance path. Prepare.

[0017] In the stapler provided with the peeling means described above, the paper is wound in a roll shape with the release paper attached to the adhesive portion provided at the position of the leg of each of the connected stables. A storage means for storing the roll-shaped stable and a discharge path for discharging the release paper peeled from the stable by the peeling means to the outside of the stapler.

[0018] In the stapler provided with the conveyance path described above, the staple located at the leading portion and the staple located at the leading portion at the cutting position where the staple located at the leading portion of the connecting stable is cut by the cutting means. There is a holding piece that holds the adjacent table against the transport path.

[0019] The cutting means has a pair of connecting portion cutting blades arranged so that the blade edges face outward in opposite directions, and the staple located at the leading portion and the staple located at the leading portion are adjacent to each other. For each of the two connecting portions between the staples, the respective cutting edges of the connecting portion cutting blades are pressed in opposite directions from the inner side to the outer side of the connecting staples to cut each connecting portion.

[0020] Further, the molding means is fitted with a receiving base having a predetermined width on which the stable cut by the cutting means is installed, and the receiving base on which the stable is installed, and the both ends of the stable in one direction. Press the both legs of the mating part that is molded into a bent shape and the legs of the stable that are molded into a shape in which both ends are folded in one direction with the cradle and the fitting part mated. A pair of pressing members.

[0021] Further, the penetrating means has two insertion cutting blades fixed in parallel at an interval corresponding to the length of the crown portion, and a stable formed into a shape in which both ends are bent in one direction. With each of the two leg portions aligned with the two insertion cutting blades, together with the insertion cutting blade, it is pushed down against the binding paper and penetrates both the leg portions of the staple.

[0022] Further, the bending means bends the first leg of one of the legs of the stable penetrating the binding paper along the binding paper in the direction of the other second leg, and in the bent state Place the first folded part to be held and the second leg of the stable on the binding paper in the direction of the first leg. A second bent portion that is bent and overlapped with a part of the first leg portion, and held in the bent state, a first leg portion that is bent and held by the first bent portion, and a second bent portion There is a bonding portion that presses the overlapping portion with the second leg portion that is bent and held by the flange portion, and bonds the two leg portions to each other at the bonding portion.

[0023] In the stapler according to the present invention, the staple located at the leading end is cut by the cutting means from the connecting stable in which a plurality of substantially straight paper stables are connected in parallel.

[0024] Thereafter, the cut stable is molded by a molding means into a shape in which both ends are bent in one direction so that a predetermined length becomes a leg from both ends. Thereafter, both legs of the molded stable are penetrated into the binding paper by the penetrating means, and both legs of the penetrated staple are folded along the binding paper by the folding means and bonded to each other.

[0025] In the conventional stapler, the binding paper is bound by a pre-formed stable, and the stable is formed of a soft material such as paper. Therefore, the staple is deformed or the staple is deformed immediately. The table could not be passed through the binding paper securely, or after the penetration, the legs of the stable could not be folded correctly to bind the binding paper. In contrast, in the stapler of the present invention, the stable is formed into a shape in which both ends are bent in one direction, and then penetrated into the binding paper, and both legs are bent and bonded. As a result, it is possible to reliably bind the binding sheets using a paper-made stable table.

[0026] Further, the stapler according to the present invention includes a cutting means for cutting a staple located at the leading portion of the connected staple from a connected staple in which a plurality of substantially straight paper stables are connected in parallel, and a cutting unit. A molding means for molding the stable cut by the means into a shape in which both ends are bent in one direction with a predetermined length from both ends, and both legs of the stable molded by the molding means, The forming means comprises cutting means for penetrating the binding paper, and bending means for bending both legs of the stable penetrated through the binding paper by the penetrating means along the binding paper and bonding them together. Fits a cradle with a predetermined width and a cradle on which the stable is installed, and the stable is bent in both directions. And the fitting portion to be, It is good also as having a pressing member which presses both the leg parts of the staple which were formed in the shape where the cradle and the fitting part were fitted and bent at both ends force I direction.

[0027] In the stapler described above, the pressing member is molded into a shape in which both ends are bent in one direction in conjunction with the retraction of the fitting portion from the cradle after the fitting portion is fitted to the cradle. Hold both legs of the staple from both sides.

[0028] In the stapler according to the present invention, the staple located at the leading end of the connection stable is cut from the connection stable by connecting a plurality of substantially straight paper stables in parallel by the cutting means. Thereafter, the stable cut by the cutting means is formed by the forming means into a shape bent in the direction of the force at both ends so that a predetermined length from both ends becomes the leg portions. The stable is molded by the molding means as follows.

[0029] First, the cradle on which the cut stable is installed and the fitting portion are fitted, and the staple is molded into a shape in which both ends are bent in one direction. Both legs of the stable molded into a shape with both ends bent in one direction are pressed from both sides by the pressing members. For this reason, it is prevented that both legs are opened by the spring back.

[0030] After that, both legs of the molded stable are passed through the binding sheet by the penetrating means, and are bent by the both legs leg force S of the penetrating stable and the folding means, and are bonded to each other.

[0031] Now, in order to increase the number of staples that can be loaded, when using straight staples, both ends must be in one direction after cutting the staple at the beginning of the connected stable before passing through the binding paper. It is necessary to mold into a bent shape.

[0032] In this way, when the separated stable is bent into a shape bent in the direction of the force at both ends, the bending deformation is somewhat restored by the elasticity of the stable itself (this phenomenon). Is called springback). Due to this springback, it was not possible to systematically penetrate both legs into the cut hole of the binding paper.

[0033] On the other hand, in the stapler of the present invention, both legs of the stapler molded into a shape bent in the direction of the force at both ends are pressed from both sides by the pressing member, and both legs are opened by the spring back. It is prevented. As a result, the influence of the springback after molding the stable can be suppressed, and the stable can penetrate the binding paper. It becomes possible.

[0034] Further, the stapler according to the present invention includes a cutting means for cutting a staple located at the leading portion of the connected staple from a connected staple in which a plurality of substantially straight paper stables are connected in parallel; A molding means for molding the stable cut by the means so as to form a crown part and leg parts bent at substantially right angles from the left and right of the crown part, and a stable part molded by the molding means. A moving means for moving to a penetrating standby position for waiting to pass through the binding paper, a penetrating means for penetrating both legs of the stable moved to the penetrating standby position by the moving means into the binding paper, and the penetrating means Bending means that bends both legs of the stable penetrated through the binding paper along the binding paper and bonds them together. It has a pressing member that holds both legs of the stable shaped from the outside, and the moving means is the side of the stable that has both legs pressed by the holding member. It is also possible to have a pressing member that presses and urges at least the upper and lower portions of the plate to move the stable to the penetrating standby position.

In the above-described stapler, the pressing member presses and urges the upper and lower sides of both the leg portions of the staple.

[0036] The pressing member presses and urges the side of the crown portion of the staple and the side of the lower portion of both leg portions.

[0037] Further, the push member has an engagement portion that engages with an engagement hole provided in the crown portion, and engages with the engagement hole of the crown portion of the stable, in which both leg portions are pressed by the pressing member. The engaging portion presses and urges the crown portion and presses and urges the lower sides of both leg portions.

[0038] In the stapler according to the present invention, the staple located at the head is cut by the cutting means from the connected stable in which a plurality of substantially straight paper stables are connected in parallel. The stable cut by the cutting means is formed by the forming means so as to form a crown portion and leg portions bent at substantially right angles from the left and right of the crown portion. In addition, the legs of the stable formed into a shape bent in the direction of the force at both ends are pressed by the pressing member from both outer sides.

[0039] The stable formed into a shape in which both ends are bent in one direction by the forming means is transferred. By the moving means, the stable is moved to a penetrating standby position for waiting for penetrating the binding paper. The movement of the stable by the moving means is performed by pressing and urging at least the upper part and the lower part of the side surface opposite to the direction of movement of the stable. As a result, the staple is moved to the penetrating standby position without being largely inclined.

[0040] The stable moved to the penetrating standby position by the moving means has both legs penetrate the binding sheet by the penetrating means. The stables having both leg portions penetrating the binding sheet are folded by the folding means and bonded to each other.

[0041] As described above, when straight staples are used to increase the number of staples that can be loaded, the effect of springback when the separated stable is bent into a shape bent in the direction of both-end forces. In order to suppress this, it is necessary to hold the legs of the stable molded into a shape with both ends bent in one direction by pressing members.

[0042] Here, when both legs of the stable molded into a shape in which both ends are bent in one direction are pressed by the pressing member, both legs pressed by the pressing member are pressed against the pressing member by the spring back. It is stretched out. For this reason, when the stable is moved to the penetrating standby position for penetrating the binding paper, only the crown portion of the stable is pressed and urged to move the stable. The two legs that were stretched against the holding member by the back could not follow, and the staple was not able to move correctly to the penetrating standby position.

[0043] On the other hand, in the stapler according to the present invention, at least the upper and lower portions of the side surface opposite to the moving direction of the staple formed in a shape bent in the direction of the force at both ends are pressed and urged. As a result, the sheet can be moved to the penetrating standby position for penetrating the binding sheet without being largely inclined. As a result, it is possible to move the stable post molding to the penetrating standby position with high accuracy.

[0044] Further, the stapler according to the present invention includes a plurality of binding sheet mounting portions on which binding sheets to be bound are mounted, and a plurality of paper stables that are substantially straight and have adhesive portions at predetermined positions in parallel. A cutting means for cutting the staple located at the leading end of the connected staple from the connected linked staples, and a leg that is bent by the cutting means at a substantially right angle from the left and right of the crown part and the crown part. Forming means for forming the part to be formed, A penetrating means for penetrating both legs of the stable formed by the mold means into the binding paper placed on the binding paper placing portion, and a pair of legs of the stable penetrating the binding paper by the penetrating means to the binding paper And bending means for bonding together at the adhesive portion, and the bending means binds one first leg portion of both the legs of the stable penetrating the binding paper in the direction of the other second leg portion. Folded along the paper and held in the folded state, and the second leg of the stable was held by the first bent part along the binding paper in the direction of the first leg. A second bent portion that is bent so as to overlap with a part of the first leg portion and is held in the bent state, a first leg portion that is bent and held by the first bent portion, and a second bent portion. Second folded and held By pressing the overlapping portions of the parts it may be to having a bonding portion bonded to both legs to each other with an adhesive portion.

[0045] In the above-described stapler, the bending means has a holding part that holds both legs of the stable sheet penetrating the binding sheet by the penetrating means in a direction facing each other, and holds the bent part in the bent state. The first leg bent and held by a predetermined amount in the direction of the second leg is bent along the binding sheet in the direction of the second leg at the first bent part, and the first leg is bent by the holding part. The second leg portion that is bent and held in the direction of the leg portion is bent along the binding sheet at the second bending portion in the direction of the first leg portion.

[0046] Further, the penetrating means includes a pressing portion that pushes down the stable against the binding paper, and two insertion cutting blades that are arranged in parallel at intervals according to the length of the crown portion and are fixed to the pressing portion. Each of the insertion and cutting blades is bound in a state where both legs of the stable formed into a shape bent in the direction of the force ^ at both ends by the forming means are attached to the opposite surfaces of each insertion and cutting blade. And the pressing means pushes down the stable against the binding paper, and the bending means is attached to the legs of the stable that have penetrated the binding paper by the penetration means and are attached to the surfaces of the insertion cutting blades facing each other. The first leg is held in a state where the holding part is bent by a predetermined amount in a direction facing each other, separated from the insertion cutting blade, and held by the holding part away from the insertion cutting blade. At the first bend, towards the second leg The second leg that is folded in the direction along the binding sheet and held away from the insertion cutting blade force by the holding part is bent along the binding sheet in the direction of the first leg at the second bending part. [0047] Further, the first folding portion, the second folding portion, and the bonding portion are pivotally supported so as to be rotatable on the opposite side of the binding paper placement portion of the binding paper placement portion as the bending means. Rotate the first bent part to fold and hold the first leg of the stable, hold the second bent part to fold and hold the second leg of the stable, and hold the bonded part Rotating means for attaching the first leg part and the second leg part by rotating the first leg part.

[0048] Further, the bonding portion has a long hole portion at a predetermined position, and is fixed to the base portion of the stapler as a rotating means so as to be slidable in the long hole portion of the shell-separating portion. A first folding unit and a second folding unit, each of which includes a support unit that engages and supports the bonding unit with respect to the base unit, and a pressing unit that presses down the binding paper placement unit with respect to the base unit. The panel is biased upward with respect to the bonded part.

[0049] In the stapler according to the present invention, the binding paper force placed on the binding paper placement unit is bound by a paper stable as follows. First, from a connected stable in which a plurality of paper stables having adhesive portions at predetermined positions are connected in parallel, a stable located at the top of the connected stable is cut by a cutting means. To be separated.

[0050] Thereafter, the cut staple is formed into a shape in which both ends are bent in one direction so that the crown and the leg portion bent at a substantially right and left force of the crown portion are formed by the forming means. The Thereafter, both legs of the molded stable are passed through the binding paper by the penetrating means, and both legs of the penetrating stable are bent by the bending means and bonded to each other by the bonding part.

[0051] Here, bending and bonding of both legs of the stable penetrating the binding sheet by the bending means are performed as follows. First, the first leg of one of the legs of the staple that penetrates the binding sheet is folded along the binding sheet in the direction of the other second leg by the first folding section, and held in a folded state. Is done.

[0052] After that, the second leg force S of both legs of the stable penetrating the binding paper and the second folding part are held by the first folding part along the binding paper in the direction of the first leg. The first leg is folded so as to overlap a part of the first leg, and is held in a folded state.

[0053] After that, the overlapping portion of the first leg bent and held by the first bent portion and the second leg bent and held by the second bent portion is pressed by the bonding portion. Then, both the leg portions are bonded to each other at the bonding portion.

[0054] In the conventional stapler, both the legs of the stable penetrated through the binding sheet are directed to the flat center part and the outside formed on both sides of the center part. The two legs of the stable formed of a soft material such as paper were bent by being brought into contact with the stable receiving surface of the stable receiving base. For this reason, it has not been possible to reliably perform the bending and bonding of the leg portions of the staples that have penetrated the binding paper.

[0055] On the other hand, the stapler of the present invention holds both the leg portions of the staples penetrating the binding sheet in the direction facing each other in order by the bent portions, and holds both the folded and held leg portions. The overlapping portions are pressed together by the bonding portion and bonded together. As a result, the stapler of the present invention can surely bend and bond the both legs of the paper stable penetrating the binding paper.

[0056] Further, the stapler according to the present invention includes a transport path for transporting the connected stables connected to each other at the connecting portion in a state where a plurality of substantially straight paper stables are arranged in parallel, and a transport path. Cutting means for cutting the first staple located at the leading portion of the connecting stable at the predetermined cutting position of the path and the connecting portion between the first staple and the adjacent second staple, and separating the first staple; At the cutting position, the first stable and the second stable are pressed against the conveying path, and the first stable separated by the cutting means is formed into a shape bent in the direction of both ends and bound. The leg of the first stable that penetrates the paper and bends the binding paper is bent along the binding paper and pasted together, thereby eliminating the loosening means for loosening the binding paper. good.

[0057] The above-described stapler includes transport means for transporting the connected stable on the transport path.

[0058] In addition, the conveying means includes an engaging claw that engages with a feed hole provided for each of the connected stables, and the engaging claw is pressed against the conveying path by a pressing piece. After engaging the feed hole corresponding to the staple and cutting off the first stable by the cutting means, the engaging claw is moved and the connected stable is conveyed to the cutting position.

[0059] Further, the conveying means is connected to the connection stapler according to the binding operation of the cutting means and the binding means. The moving claw is provided with a moving part attached with an engaging claw that reciprocates a predetermined distance in the conveying direction and the opposite conveying direction. When the moving part is engaged with the feed hole corresponding to the stable and moves in the direction opposite to the conveying direction of the connected stable, it is disengaged from the feed hole provided in the connected stable.

[0060] Further, the engaging claw is provided on the moving portion so as to be able to take the engaging position that has entered the feed hole provided in the connection stable and the non-engagement position that has been retracted from the feed hole. When the moving part moves in the anti-carrying direction in the engaged position, the engaging slope engages with the feed hole when the moving part moves in the carrying direction. And a non-engagement slope that generates an action of retracting the moving part to the non-engagement position in cooperation with the feed hole.

[0061] In the stapler according to the present invention, a plurality of substantially straight paper stables are arranged in parallel, and the connected stables connected to each other at the connecting portion in the state of V are transported on the transport path, At a predetermined cutting position, the connecting portion between the first staple located at the leading portion of the connecting stable and the second staple adjacent to the first staple is cut by the cutting means, and the first stable is cut off.

[0062] Here, when the connecting portion between the first staple and the second staple is cut by the cutting means, the first stable and the second stable are separated from the transport path by the pressing piece. It can be pressed.

[0063] After the first stable is cut by the cutting means, the cut first stable is formed into a shape in which both ends are bent in one direction by the binding means and penetrated into the binding paper. The first stable penetrating through the binding paper is bent at both legs and pasted together.

[0064] In the conventional stapler, when the staple located at the beginning of the linked staple is pushed downward by the push plate and separated, the staple adjacent to the staple located at the beginning stores the staple! /, It is pressed against the staple magazine! For this reason, when the head-side stable is pushed with the push plate, the adjacent staple also moves together with the head-side stable, and the head-side staple is separated with high accuracy. I couldn't do it.

[0065] In contrast, in the stapler of the present invention, the cut located at the leading portion of the linked staples. When the connecting portion between the staple to be separated and the staple to be separated and the adjacent staple is cut, the staple to be separated and the staple adjacent to the staple to be separated are separated by a holding piece. Is pressed against. Therefore, it is possible to separate the stable located at the end of the connecting stable with high accuracy.

[0066] In addition, the stapler according to the present invention includes a connection stable in which a plurality of substantially straight paper stables arranged side by side are connected to each other by a plurality of connection portions, and is connected to the front of the connection stable. A cutting means for cutting the first stable, and the first stable cut by the cutting means is formed into a shape bent in the direction of the force at both ends, penetrates the binding paper, and the first staple penetrates the binding paper. The table has a binding means for binding the binding paper by bending the legs of the table along the binding paper and bonding them together, and the cutting means is a pair of couplings arranged so that the blade edges face outward in opposite directions. For each connecting part between the first staple and the second stable adjacent to the first stable, the connecting part is cut from the inside to the outside of the connecting staple. Each blade edge of the blade It is also possible to press each other in the opposite direction and cut each connecting part.

[0067] In the stapler described above, the cutting means is arranged such that the blade tips of the pair of connecting portion cutting blades correspond to the inside of the connecting staple, and the blade base portion corresponds to the outside of the connecting stable. In addition to arranging the pair of connecting part cutting blades linearly with respect to the connecting stable, each connecting part between the first stable and the second stable is directed from the inside to the outside. And a moving means for pressing the pair of connecting portion cutting blades so as to cut sequentially.

[0068] In the stapler according to the present invention, the plurality of substantially straight paper staples arranged side by side by the cutting means are connected to each other at the plurality of connecting portions, and the first stable is located at the leading portion. Is disconnected.

Here, the cutting of the first staple by the cutting means is performed as follows. For each connecting portion between the first staple located at the beginning of the connecting staple and the adjacent second staple, each cutting edge of the pair of connecting cutting blades extends from the inside to the outside of the connecting staple. Each of the connecting portions is cut by being pressed in opposite directions. As a result, when the connecting portion is cut, the opposite force is applied to the first staple and the second staple by the respective blade edges. Are added at the same time.

[0070] After the first staple located at the leading portion of the connected staples is cut by the cutting means, the first staple cut by the binding means is formed into a shape bent in the direction of both end forces ^ and bound. Penetration into the paper. The legs of the first stable penetrating through the binding paper are folded and bonded together.

[0071] In the conventional stapler, the staple located at the head in the staple magazine is separated from the other staplers by being pushed downward by the push plate. In the method of separating the stapler by pushing downward with this push plate, the height of the separated staple and other staples is greatly different after separation.

For this reason, in order to separate the staples without changing the height, it is necessary to cut the connecting portion of the stable with the cutting blade. Here, in order to stably cut the staple connecting portion by the cutting blade, it is necessary to support the staple to be cut in a wide range, and the configuration for cutting becomes complicated.

[0073] On the other hand, in the stapler of the present invention, the blade tips of the pair of connecting portion cutting blades are pressed against the connecting portions of the stable in the opposite directions from the inside to the outside of the connecting stable. Thus, each connecting portion of the staple is cut. For this reason, the staple is cut in a state in which an outward force is simultaneously applied to the staple to be cut and the staple adjacent to the staple to be cut by the blade edge in the longitudinal direction of the staple. Therefore, it is possible to stably perform the stable cutting with a simple configuration in which the staple to be cut and the staple adjacent to the staple to be cut are not supported in a wide range.

[0074] Further, the stapler according to the present invention is substantially straight, and the connected staples in which a plurality of paper staples having adhesive portions at predetermined positions on the back surface are connected in parallel are conveyed with the back surface of each staple facing downward.

In a slanting posture, the staple 3Aa and the staple 3Ab are pressed against the transport path 13 at their respective ends. Therefore, the staple 3Aa and the staple 3Ab are pressed against the conveying path 13 by the first check panel 59a and the second check panel 59b, respectively, and connected in the direction indicated by the arrows in FIGS. 24A and 24B. 2 can be moved.

[0176] Next, a method of cutting, forming and conveying the staple 3A positioned at the end of the linked staple 2 by the staple cutting and forming unit will be described with reference to Figs. 25A to 25E. FIG. 25A, FIG. 25B, FIG. 25C, FIG. 25D, and FIG. 25E are explanatory views of the method for cutting, forming, and conveying the staple 3A, with the connected staple 2, the check spring 59, and the feed catch 4 4 cut. Shown in state. In FIGS. 25A, 25B, 25C, 25D and 25E, the stable located behind the stable formed into a shape folded in the direction of the force at both ends must not be cut! /

[0177] FIG. 25A shows the staples 3A, the check springs 59, and the feed catches 44 in the standby state of the stapler 1A. As in FIGS. 24A and 24B, the staple 3Aa is the staple 3A at the leading end of the connecting staple 2, and is located on the receiving table 13c below the forming plate 15. The staple 3Ab is a staple 3A located next to the staple loading unit side of the staple 3Aa. The staple 3Ac is already formed into a shape in which both ends are bent in one direction and connected to the stable blade 2 by a cutting blade 49 described later. The staple 3A is located below the driver 18 in a state where the staple 3 is separated from the staple. In FIG. 25B and later,! /, Staple 3Ac is displayed! /, NA! / ,. [0178] FIG. 25B shows a state where the feed latch 44 is moving downward. FIG. 25C shows a state in which the connecting portion between the staple 3Aa and the staple 3Ab is cut by the cutting blade 49. FIG. FIG. 25D shows a state in which the staple 3Aa is formed by the forming plate 15. FIG. 25E shows a state in which the linked staple 2 is moved by the feed latch 44 and the staple 3Aa is moved forward by the staple pushing portion 17a of the pusher 17.

[0179] When the handle 5 is pushed down from the standby state of the stapler 1A shown in FIG. 25A, the driver 18 descends, the link 57 rotates, and the pusher 17 moves rearward. As a result, as shown in FIGS. 25B and 25C, the feed latch 44 rotates and moves backward, and the engagement portion 44c of the feed latch 44 is moved to the staple loading portion side of the staple 3Aa (see FIG. 25B). The right side) is disengaged from the feed hole 3 2 and is engaged with the feed hole 32 on the staple loading section side of the staple 3Ab.

Here, as shown in FIG. 24B, the staple 3Ab is pressed against the conveyance path 13 shown in FIG. 16 and the like by the second check spring 59b of the check spring 59. For this reason, it is possible to prevent the staple 3Ab from being lifted from the transport path 13, and the engaging portion 44c of the feeding catch 44 can be reliably engaged with the feeding hole 32 on the staple loading portion side of the staple 3Ab.

[0181] Further, during the time shown in FIG. 25A to FIG. 25C, the forming plate 15 is lowered by being pushed down by the driver 18. Details of pushing down the forming plate 15 by the driver 18 will be described later. When the forming plate 15 having the cutting blade 49 is lowered with respect to the connecting step 2, the connecting portion between the staple 3Aa and the staple 3 Ab is cut by the cutting blade 49. FIG. 26A, FIG. 26B and FIG. 26C are explanatory views showing the cutting of the staple 3A by the cutting blade 49 in time series.

[0182] As shown in Fig. 26A, Fig. 26B and Fig. 26C, the two cutting blades 49 are lowered with respect to the staple 3A, whereby the staple connecting portions 34 are cut at the cutting edges 49a of the two cutting blades 49. Is done. Here, each blade edge 49a is pressed against the staple connecting portion 34 between the staple 3Aa and the staple 3Ab in the opposite direction from the inside to the outside of the staple 3A, so that each staple connecting portion 34 is Disconnected. As a result, when each staple connecting portion 34 is cut, the staple 3A is connected to the staple 3Aa and the staple 3Ab. In the longitudinal direction, a force in the opposite direction is simultaneously applied by each blade edge 49a.

[0183] Thus, the staple 3A can be stably formed by the simple configuration in which the staple 3Aa to be cut and the staple 3Ab adjacent to the staple 3Aa to be cut are held by the check panel 59 which does not need to be supported in a wide range. Cutting can be performed.

[0184] After cutting the staple connecting portion 34 of the staple 3Aa and the staple 3Ab in Fig. 26C, the forming plate 15 is further lowered to form the staple 3Aa into a shape in which both ends are bent in one direction. 27A, 27B, and 27C, and FIGS. 28A, 28B, and 28C are explanatory views showing the formation of the staple 3A by the cradle part 13c and the forming plate 15 in time series.

[0185] As shown in FIGS. 27A, 27B, 27C, and 28A, the forming plate 15 is lowered with respect to the staple 3Aa that is installed in the cradle part 13c and separated from the adjacent staple 3A. The portion 13c and the staple forming portion 15a are fitted. As a result, the staple 3Aa is molded into a shape in which both ends are bent in one direction so as to form a crown portion 35 and a leg portion 36 bent substantially at right angles from the crown portion 35.

Further, as shown in FIG. 28A, after forming the staple 3Aa into a shape in which both ends are bent in one direction, the driver 18 rises, so that the forming plate 15 also rises. Details of the rise of the driver 18 and the forming plate 15 will be described later. Here, as shown in FIGS. 28B and 28C, when the forming plate 15 is raised, both legs 36 of the staple 3Aa formed into a shape in which both ends are bent in one direction are pressed by the flat face 15c. FIG. 29 is a perspective view showing a state in which both legs 36 of the stable 3Aa are held by the flat plate 15c of the forming plate 15 that has been lifted. In this way, by holding the both leg portions 36 from the both outer sides by the Hiratsae 15c, it is possible to prevent the both leg portions 36 of the staple 3Aa from being opened by the springback. As a result, it is possible to suppress the influence of the spring back after the staple 3Aa is formed into a shape bent in both end force directions, and to perform the next process with high accuracy.

[0187] After the forming plate 15 is raised and the legs 36 of the stable 3Aa having both ends bent in one direction by the Hirasae 15c are held, the driver 18 is further raised and linked. 57 rotates and pusher 17 biased by pusher spring 16 moves forward. Move towards. As a result, as shown by arrow 1 in FIG. 25E, the linked staple 2 is moved forward by the feed latch 44, and the staple 3Aa is pushed forward by the not-shown stable pushing portion 17a as shown by the arrow k. It is. As a result, the staple 3Aa shown in FIG. 25E is equivalent to the staple 3Ac shown in FIG. 25A.

30A, 30B and 31 are explanatory views showing a method of pushing out the staple 3A by the staple pushing portion 17a of the pusher 17. FIG. As shown in FIG. 30B, when the pusher 17 is moved forward, the staple 3A is bent in the direction of both ends by the stable pushing portion 17a, so that the two cutting blades 51 of the driver 18 from the forming plate 15 Extruded in between. At this time, the pushing out of the stable 3Aa by the stable pushing portion 17a is caused by the four protrusions 17aa provided on the staple pushing portion 17a on the back side of the both leg portions 36 of the staple 3A as shown in FIG. This is done by pressing the top and bottom.

Thereby, the staple 3A is moved between the two punching blades 51 of the driver 18 in the forming plate 15 in which the staple 3Aa is not largely inclined. Therefore, it is possible to move the staple 3A from the inside of the forming plate 15 to the two cutting blades 51 of the driver 18 with high accuracy.

FIG. 32 is an explanatory view showing a staple pushing portion 17b of another example of the pusher 17. As shown in FIG. 32, the staple pushing portion 17b may be configured to include three projecting portions 17bb. The staple pusher 17b shown in FIG. 32 causes the three protrusions 17bb force provided on the stable pusher 17b b to push the back part of the crown part of the staple 3Aa and the lower part on the back side of both leg parts 36, thereby stapling. 3Aa is extruded.

[0191] As a result, the staple 3Aa is not inclined greatly, and the internal force of the forming plate 15 is also moved between the two extraction blades 51 of the driver 18 in the same manner as the staple pushing portion 17a shown in FIG. Therefore, it is possible to move the staple 3Aa from the forming plate 15 to the space between the two punching blades 51 of the dryer 18 with high accuracy.

[0192] When the staple 3A having an engagement hole in the crown portion 35 is used, the staple pushing portion 17b of the pusher 17 is engaged with the engagement portion that engages with the crown portion 35, and the lower portion on the back side of both leg portions 36. It is also possible to push out the staple by pressing the crown portion 35 with the engaging portion and pushing the lower part of the back side of the both leg portions 36 with the pushing portion. Thus, similar to the staple pushing part 17a shown in FIG. 31 and the staple pushing part 17b shown in FIG. 32, the two punching blades 51 of the driver 18 from the inside of the forming plate 15 where the stable 3A does not largely tilt. During this time, the staple 3A is moved, and the internal force of the forming plate 15 of the staple 3A can be moved between the two extraction blades 51 of the driver 18 with high accuracy.

As a result, as shown in FIG. 25E, the linked staple 2 is conveyed forward by the feeding catch 44. At this time, as shown in FIG. 10, the release paper 30 is peeled off by the peeling block 38 from the connected stable 2 drawn out from the roll-shaped staple 4 loaded in the staple holder 11. Also, the peeled release paper 30 is discharged from the release paper discharge port 39 via the release paper discharge path 40. Further, the staple 3Aa is pushed out between the punching blades 51 of the driver 18 by the staple pushing portion 17a of the pusher 17 (not shown in FIG. 25E). The extruded staple 3Aa becomes a new staple 3Ac shown in FIG. 40 through a state shown in FIG. 60 described later.

59, 73 and 94 are explanatory views showing the state of each part of the stapler 1A in a state where the return of the sheet presser 19 is started. The driver 18 is further moved upward by the torsion coil panel 56 from the state where the pusher 17 starts to move forward as shown in FIGS. As a result, as shown in FIG.を Move up inside A46 to the specified position.

[0283] After the driver 18 has been raised to a predetermined position by the torsion coil spring 56, the tension spring 55 provided between the frame 8 and the sheet retainer 19 shown in FIG. Lifting upward with respect to 8 is started.

60, 74 and 95 are explanatory views showing the state of each part of the stapler 1A in a state immediately before the pusher 17 returns. 59, 73 and 94, from the state in which the return of the sheet presser 19 is started, the sheet presser 19 and the driver 1 8 force frame 8 are further lifted upward by the pull panel 55.

[0285] When the driver 18 moves upward, the link 57 further rotates in the direction opposite to the arrow E in FIG. 2, and the long hole 57a of the link 57 holding the pusher shaft 58 moves. Then, the pusher 17 biased by the pusher spring 16 moves to the same position as in the standby state shown in FIGS. When the driver is completely in the standby state, the front of the stable molded into a shape in which both ends are bent in one direction is released, so that the compressed state is maintained. The pusher 17 moves forward by the elasticity of the pusher spring 16. For this reason, the feeding operation of the stable formed into a shape where both ends are bent in one direction and the feeding operation of other staples are performed almost simultaneously.

[0286] By the operation of each part of the stapler 1A as described above, the binding sheet 37 set on the table 20 in the sheet tray entrance is bound by the staple 3Aa.

[0287] In the stapler 1A of the present invention, the staple 3A is molded into a shape in which predetermined both ends are folded in one direction, and then penetrated through the binding sheet 37, and both leg portions 36 are folded and bonded. This makes it possible to reliably bind the binding sheets 37 using the paper stable 3A that is easily deformed.

[0288] As shown in Fig. 8A, the stapler 1A of the present invention uses a connection stapler 2 to which a substantially straight stapler 3 is connected. Further, as shown in FIG. 9A, a connecting stapler 2 in which a plurality of substantially straight staplers 3 are connected in parallel can be wound as a roll-like staple 4 in a roll shape. Thus, the staple 1 of the present invention can be loaded with a large number of stables 3A as the roll-shaped staple 4 at a time.

[0289] According to the stapler 1A of the present invention, the sheet presser 19 includes the square window 19b that can be freely opened and closed. As a result, when the staple 3A is jammed during the stapler 1A operation, such as when moving the staple 3A to the extraction blade 51, the square window 19b is opened and the jammed staple 3A is accessed by opening the square window 19b. Removal can be easily performed

[0290] The stapler 1A of the present invention pushes down the handle 5 to push down the forming plate 15 against the staple 3Aa located at the end of the linked staple 2 to perform cutting and molding, and to the binding paper 37. Push down the screwdriver 18 to penetrate the stable 3A c. As a result, the staple 3A can be cut, molded, and penetrated into the binding sheet 37 by one operation.

[0291] Further, in the stapler 1A of the present invention, as shown in FIG. 40 and the like, the binding paper 37 in a state where the binding paper 37 set on the table 20 is pressed by the paper pressing portion 19d of the paper presser 19 is used. The stable 3A is penetrated with respect to 37, and both legs 36 that are penetrated are bent and bonded. As a result, the staple 3A penetrates and penetrates the binding paper 37. Further, it is possible to perform operations such as bending and bonding of both leg portions 36 with high accuracy.

[0292] Further, in the stapler 1A of the present invention, the driver 18 is pushed by the driver pusher 66 attached to the handle 5, and the driver 18 is pushed down with respect to the binding sheet 37. Also V? By engaging the protruding pin 18d with the lower end 46a of the flange 46, the forming plate 15 is pushed down against the staple 3A together with the driver 18.

[0293] Furthermore, in the stapler 1A of the present invention, the driver 18 is pushed upward from the binding paper 37 by being pushed by the torsion coil spring 56 provided between the driver 18 and the paper presser 19. Also V? By engaging the protruding pin 18d with the collar 48a, the forming plate 15 is pushed up from the staple 3A together with the driver 18.

[0294] Further, the protruding pin 18d is not engaged in the V 'groove 46 and the flat portion 47 other than the lower end portion 46a, only the driver 18 moves up and down, and the forming plate 15 does not move up and down. That is, in the stapler 1A of the present invention, it is possible to interlock the push-down and push-up of the driver 18 and the forming plate 15 only at predetermined positions above and below the driver 18.

[0295] Further, the stapler 1A of the present invention cuts and molds the stapler 3a by the forming plate 15 and penetrates the stapler 3c into the binding sheet 37 by the driver 18 in one operation shown in FIGS. 40 to 60. Then, the pusher 17 moves the stapler 3a cut and molded by the forming plate 15 to the driver 18. In other words, the cutting and molding for one staple 3A and the penetration to the binding paper 37 are performed in different operations at different positions.

[0296] This shortens the vertical stroke of each actuating member as compared to a configuration in which cutting and molding for one staple 3A and penetration of the binding paper 37 are performed at the same place in a single operation. Therefore, the height of the stable can be reduced.

[0297] Further, the stapler 1A of the present invention has a conveyance path groove 13a that avoids contact with the adhesive portion 31 on the back surface of each stable 3A in the conveyance path 13 in which the connection stable 2 is conveyed. For this reason, when the connected stable 2 is transported along the transport path 13, the adhesive 31 on the back surface of each stable 3A and the transport path 31 do not contact each other, and the transport of the connected stable 2 can be performed smoothly. become

Yes [0298] Further, in the stapler 1A of the present invention, when the staple 3A located at the end of the connected staple 2 and the staple 3Ab adjacent to the staple 3Ab are cut by the 34 force cutting blade 49, The staple 3Aa and the staple 3Ab are pressed against the conveyance path 13 by the check panel 59, respectively. For this reason, the stable 3Aa located at the end of the connecting stable 2 can be separated with high accuracy.

[0299] In the stapler 1A of the present invention, each staple connecting portion 34 is pressed in the opposite direction from the inner side to the outer side of each blade edge 49a 1S stable 3A, so that each staple connecting portion 34 is Disconnected. As a result, when each staple connecting portion 34 is cut, a force in the opposite direction is simultaneously applied in the longitudinal direction of each staple 3A by each blade edge 49a.

[0300] Thus, the staple 3A can be stably held by the non-return panel 59 that does not need to support the staple 3Aa to be cut and the staple 3Ab adjacent to the staple 3Aa to be cut in a wide range. Cutting can be performed.

[0301] Further, the stapler 1A of the present invention has a protruding portion 51d formed by projecting a part in the width direction as a cutting blade 51 provided with a notch hole in the binding paper 37 for penetrating the staple 3A. And a cutting blade having a shape having a linear portion connected in the longitudinal direction from one end to the other end. Thereby, the strength of the punching blade 51 when penetrating the binding paper 37 is ensured, and the staple 3A can be reliably penetrated into the binding paper 37.

[0302] In addition, according to the stapler 1A including the first punching blade 51a shown in Figs. 21A, 21B, and 21C, when the legs 36 of the stapler 3 are passed through the binding sheet 37, the stapler 1 is shown in Fig. 21D. Thus, a cut hole 52a having a wide width in the direction of the arrow is formed. As a result, both the leg portions 36 of the staple 3A can be surely passed through the binding sheet 37.

[0303] Further, according to the stapler 1A including the second punching blade 51b shown in FIGS. 22A, 22B, and 22C, when the legs 36 of the stapler 3 are passed through the binding paper 37, the stapler 1 is shown in FIG. 22D. Thus, unlike the notch hole 52a, the notch hole 52b having a wide width in the arrow direction over the entire width is formed. Accordingly, it is possible to more reliably pass both the leg portions 36 of the staple 3A with respect to the binding sheet 37 as compared with the stapler 1A including the first extraction blade 51a. [0304] The stapler 1A of the present invention bends both the leg portions 36 of the staple 3A penetrated through the binding paper 37 in order along the binding paper 37 by the clincher light 61 and the clincher left 60 in a direction facing each other. The overlapping portions of both leg portions that are held and bent are pressed by the clincher center 27 and bonded together. As a result, the stapler 1A of the present invention can reliably fold and bond the both leg portions 36 of the paper staple 3A passed through the binding paper 37.
