Permeation = use; Figure 86 The stapler kicker arm 3' is completely "19", the engaging piece m of the member 19 is abutted against the other end portion 3Gb of the member 30, and the sliding member is moved away from the (four) drive to cause the slide member 19 to start moving. This form ~, you are in the hunting drive state 丨 3 will be nailed from the < use, my position timing occurs. Then, as the arm 6 is pressed down, and the V end portion 3°b causes the engaging piece (10) of the sliding member 19 to be rearward, the sliding member 19 moves backward against the compression spring 29 =. The area of the lower surface 18a of the guide member 18 is moved to the rear side by the sliding structure. Further, the bending device 16 is pressed against the urging force of the compression spring 22. Since the biasing force of the compression spring that urges the b-bend 16 upward is extremely weak, the tip end portion of the leg portion of the staple penetrates the binding paper and is used for binding from the paper. The lower side of the needle protrudes, and the foot of the needle is pressed down. Therefore, at this moment, the effect of bending the staple portion of the staple is not achieved. Then, as with the stapler of Figure 9A! As shown, by the push-down operation of the arm 6, the other side of the link member 3 is slid toward the slide member 19; After 9b, continue to slide. At this time, the slide member 19 that supports the bending guide 18 at the upper position is moved forward and backward in the region of the lower surface 18a of the curved guide 18, and is pressed by the I-retracted spring 45 shown in Fig. 7 The needle g mechanism 2, using the compression force dream 2237^9612-pf 23 200909153 4 5's force to push the curved guide 18 downward by one side of the foot of the nail cover . Further, by the sliding member 彳〇 # ^ EJt being displaced by the movement of 19, the sliding member 19's 'J wall 19d pushes the end of the compression spring watt α. Since the other of the compression springs 29 abuts against the front wall surface 23b of the five claws 23 of the bending guide 18, the load of the sliding member 19 is required to be displaced by the compression spring 2 The guide 18 propagates. However, in the >, since the projections 26 provided on both side faces of the curved guide 18 abut against the guide faces ia of the curved wall ς ^ #5, the curved member 18 does not follow the sliding ceremony, the number 1 9 Displacement and displacement, by the contraction of the compression bomb, absorb the load that wants to dry the sliding member - & As a result, 奘#田上, which is placed above the curved guide 18, n ^

The mounting paper 40 is not displaced in response to the displacement of the sliding member. The front end of the foot of the staple that has passed through the binding sheet 4 is not released from the groove portion of the bender 16 until the support portion 19a of the slide member 19 is separated from the region of the lower surface 18a of the curved guide member 18. According to the stapler shown in FIG. 9B, when the support portion 19a of the slide member is disengaged from the region of the lower surface 18a of the curved guide 18 by the further pressing operation of the arm 6 'the drive arm 3 is rotated again' The curved guide 18 can swing downward. At this time, the front end of the leg of the staple that has been struck by the driver 13 abuts against the bender groove 20a, and becomes the bender (four). In this state, when the f-curved guide 18 is swung downward, the leg portion of the staple is flatly bent along the back surface of the binding sheets J?, A40 by the test piece 20a. By this bending, the staple binding processing ends. Thus, according to the stapler i of the embodiment, in the case where the foot of the staple is flatly bent by the flat bending mechanism 2237-9612-PF 24 200909153, the horse is at least the front end of the foot of the staple. The sliding member 19 can be completely slid through the binding paper 4, so that the sliding member 19 can be slid, so that when the arm 6 is pressed, the foot of the staple can be gradually passed through the binding sheet. The peak value of the penetrating load and the link member 30 are staggered so that the value of the slanting of the slidable material is shifted. Because & 'distracts the peak value of the binding load: so it can be reduced by the driving arm 3 and the arm 6 as the main s from the month /± month 〇 X as a reaction force

Next, referring to Fig. 15 to Fig. 17, a configuration example of the bender 16 of the stapler i will be described. In the present embodiment, it is possible to provide a bender 16 which has a groove angle Θ, a depth d, and a groove width which are required for the bending of the staple 33 as shown in Fig. 7 * The curved shape of the three elements. The bending device 16 shown in Figure 15 is assembled in the needle, the J machine, and the nail

The leg of the stylus 33 is bent flat (see the 18th UD group). The bender 16 has a body portion 20 having a convex shape and a convex portion, and the upper portion of the body portion has a groove portion (hereinafter referred to as a bender groove 20a). The lower side of the main body portion 20 2237-9612-PF 29 200909153 has a bifurcation portion (protrusion), which is used when the lower force is applied from the upper portion of the bender 16 In this example, the step portion 20b is disposed between the left and right wall faces of the upper portion of the body portion 20 forming the bender groove 20a and the front and rear wall faces. For example, the bender groove 20a is formed. The left and right wall surfaces are formed with an inclined protrusion shape on the inner side, and are configured to pick up the leg portions of the staples 33 shown in Fig. 17. In this manner, when bending, it is possible to appropriately pick up and fall through. The leg portion 33 of the binding sheet 40 of the step portion 20b is inserted into the leg portion 33 of the step portion 20b. The body portion 2A shown in Fig. 16A has a thickness t of about 2 mm. The upper portion of the bender body portion 20, as shown in Fig. 6 has The upper surface of the curved shape, the wall surface of the left and right circular arc shape, and the wall surface of the front and rear inclined surface shape form the curved groove 2a by these surfaces. In this example, the step portion 20b shown in Fig. 6 6B is placed on the bender body. Between the left and right walls of the upper part of the section 2 and the inclined wall of the front and rear In Fig. 16B, Δh is the height of the step portion 2〇b. Here, the height from the first reference position P〇 to the vertex Pmax of the body portion 2〇 is set to hi 'from the reference position p〇 to When the height of the uppermost point P of the inclined wall surface of the main body portion 2 is h2, the south degree Ah, gp, Δ h = hi - h2 (1) is calculated by the equation (1) indicating the difference between the height hi and the height h2. Wherein the 'first reference position p〇, for example, when the bender 16 is placed on the reference plane', means the position belonging to the reference plane. On the other hand, 'from the reference position P to the lowest point Pmin of the bender groove 20a When the south degree is set to h3, the depth d of the bending groove 20a 2237-9612-PF 30 200909153 is calculated by the formula (2), that is, d = hl-h3 (2) The groove depth on the surface of the writing device 16 is Dl=d' Ah (3), substituting the equations (1) and (2) into the equation (3), and obtaining dl=h2 - h3. If the groove depth on the surface of the bender 16 is appropriately set When the dl is bent, the bender 16 can appropriately pick up the staples 33 that pass through the binding sheets 4〇 that fall into the step portion 2〇b (refer to the 18th βFig.), and according to the figure as shown in FIG. Comparative example The bending device 1 6 ′ is not provided with the step portion shown in FIG. 6B in the main body portion 20′′, that is, the height hl′ from the reference position p〇 to the member point Pmax of the body portion 20 to The height h3 of the bottommost point of the bender groove 20a' is calculated by d = hl - h3, and the groove depth 20a of the bender groove 20a is calculated. In the bender groove 20a of the comparative example, the groove depth d, and The groove depth dl on the surface of the curved benefit 16 of the invention has the relationship of the formula (4). Dl <d, (4) If the groove depth d' of the bender groove 2〇a' of the bender 16' of the comparative example according to the formula (4) is more than the bender of the present invention The groove depth on the surface of 16 is deep. Therefore, according to the bender 16' of the comparative example, although the flow of the staples 33 is good, but because the groove depth is deep, the distance between the back surface of the binding sheet and the upper portion of the upper portion of the bender 16 forming the bender groove 20a is large. And there are questions that are not correct in bending. Therefore, according to the present invention, the groove on the surface is made by the step portion 2〇b

2237-9612-PF 31 200909153 Zhu d 1 is shallower than the comparative example, and the groove angle is set. The groove depth d' of the curved groove 20a' is defined and penetrated through the binding sheets 4, and the shape of the bender 16 can be set to Π 9Π ^ ^ The foot of the 33 pin 33 is engaged to bend the groove 20a The foot is curved into... formed on the plan view, the rectangular shape is based on the shape, and the upper portion of the body portion 20 of the bender ib forming the bender groove 20a is in the upper part of the body portion 20 of the bender ib. The direction forms a circular arc-shaped side wall, and the two ends in the longitudinal direction have a size of 4 ^ ^ ^ m ^ $, and at the four corners thereof, the bending portion in the longitudinal direction and the wide sound 9i) h ^ w The arcuate portion of the direction is in contact via the boundary of the step portion 20b. According to the seven-character 1f curved state 16 shown in Fig. 17, the upper surface of the upper portion of the main body portion 2 of the bender 16 forming the curved groove 20a is formed into a predetermined shape. As an example of the above, the central portion of the formation of the palladium 4t4 I and the back curve of the both sides forming the depressions are formed from the lowermost portion (the bottom point Pm i η) of the curved groove 2 to the step portion 20b. The vertical distance is the depth d=( dl + Ah) of the bender groove 20a of the bend x #曲益16. Further, in the bender 16 shown in Fig. 17, the second reference position P2 is set to the main body portion 2 of the bender 16. a lower portion of the line extending from the reference position μ in a predetermined direction and an extension line extending from the inner inclined position of the upper portion of the body portion 20 of the bender 16 forming the bender groove toward the predetermined direction constitutes the bender 16 Slot angle 0. In this example, the groove angle Θ of the twister 丨6 is set to a state in which the depth d=(dl + Ah) of the bender groove of the bender 丨6 which contributes to the bending of the leg portion of the staple 33 is maintained. It contributes to the angle of the flow of the foot of the needle 33. 2237-9612-PF 32 200909153 In this manner, the shape of the bender 满足 which satisfies the three elements of the pickup of the staple 33, the flow of the leg portion of the staple 33, and the bending of the staple 33 can be set. Therefore, the bending operation of the stapler 1 to bend the leg portion of the staple 33 can be improved while maintaining the durability and the binding performance of the bender. In this example, the distance between the uppermost point P of the inclined wall surface on the left side of the bender groove 20a and the uppermost slope of the right side inclined wall surface is set as the groove of the bender slave 20a. When the width w (refer to the _ 曲 of the J7 9), the binding sheet 4q through which the staples 33 are inserted can be pushed by the month P of the needle-twisting mechanism 2, and falls into the segment ZU b. Next, referring to FIG. 18A And Fig. 18B, ^ 1 R λ,. The function example of ... 16 when the redundan paper is bent. In this example, the groove angle (four) is set to the groove depth d = dl + Ah ' required for the large b motion. By this setting, since the groove width w is narrowed, the slope (protrusion) of v:= is provided on the left and right of the bender 16. These are used as bending conditions, according to Fig. 18A: In the state before the bending of the paper for the foot and before the bending, the upper portion of the binding paper 4 of the bending device 16 is reached from the hitting fine of the needle g 9 shown in Fig. 8B.

Hole portion ? η 1. ψ 杂 / y , 丨 201 工 中 中 中 47 47 47 47 47 47 47 47 47 47 47 工 工 工 工 工 工 工 工 工 工 工 SUS SUS SUS SUS SUS SUS SUS SUS SUS SUS SUS SUS SUS SUS SUS SUS SUS SUS SUS SUS The manner in which the opening portion 201 of the protrusion portion 21b is in the middle of the process is to enter the middle sodium 47. From the inside of the curved arm 5, the wear Φ R _p r . The hollow pin 47 is pressed against the lower side of the large portion 5f and k as the top dead center. Then, the φ private one is used to smash the main shaft 41 and the hole portions 5b and 5c (the shaft hole) for the bearing. The carrier (shaft support mechanism) is assembled. In this way, the pair of openings may be provided on the bottom surface of the bending arm 5 as in the conventional example, and the number of holes through which the pin can pass is also reduced (10). In the present invention, the pin passes through the four openings. In the present invention, only one of them is simple, and it is simple to assemble. Moreover, it is not necessary to cover the cover member for preventing the hollow pin 47 from falling off. Next > ',, 25A and Fig. 25B is a view showing an operation example of the rotation restricting mechanism, which is based on the waiting rotation rotation restricting mechanism 80 shown in Fig. 25A of the Y1-Y1 arrow sectional view of the rotation restricting mechanism (10) shown in Fig. 24, from the needle s 9 The pusher guide u protruded from the bottom surface; the upper portion 21b penetrates the opening portion 201 through the hollow pin 47 which is shorter than the inner width of the curved arm 5, and the projection portion 5f provided on the inner side of the f-curved arm 5, ^, the lower side holds the hollow pin '47, so it becomes the g state in which the top dead center is stationary. The force of pressing the hollow pin 47 against the projections 5f, 5g is achieved by the urging force of the compression spring 46 shown in Fig. 2 2237-9612-PF 38 200909153 If the rotation restricting mechanism 80 is pressed in accordance with Fig. 25B, when it is bent, 'because the dream is supplied from the upper portion of the butt 9.

In the figure, the rotation of the S3 needle 9 is marked as the hollow pin 47. , and the distance between the bottom dead center and the other 'release the needle 9 ^ A, when the force is strong, use the force of the compression magazine 45, drive the arm 3, the handle", and hit 0 hand # 6 And the handle cover 36 is returned to the original position and the needle E9__25a is returned to the bending arm R, and the team core restores the protrusion 5f on the second side of the lock 4, and the lower side bears against the hollow pin 47 to remain in the The state of the top dead center is still. Thus, if the nail is rotated according to the present invention, since the horse is in the limit (4) mechanism 2, the test arm 5, and the needle machine limit mechanism 80, Between the red cymbal mechanism 2, the protrusions on the inner side of the upper portion 5 of the cymbal mechanism 2 are located: the point ..." the inner side of the arm arm 5 can limit the hollow = position. 'Because it is considered to be about the rotation of the conventional side 4 in the bending, it is also possible to prevent the pin from coming off the cover portion. 2237-9612-pp 39 200909153 In this example, the hollow pin 47 is vacant from * 4 ^ The protrusion 21b of the corner teeth, although the lunar month is applied to the protrusion 21b extending from the sliding body portion 2ja toward the buck. The situation 'is not limited to this, but it can also be applied to the opposite sides of the back of the needle 9 as in the stapler of the white method. In this case, 圩

A cut-out hole portion is formed in which both ends of the back sides of the back side of the hollow pin 4 are made of the hollow pin 4 7 so that the bent arm 5 is bent into 5 by the projections 5f, 5g钿 Abut. Next, a configuration example of the rotation restricting mechanism 90 for the drive arm of the book reader will be described with reference to FIGS. 26A and 26B. The first drawing shows a cross-sectional view when the handle is opened, and the 26B shows a partial enlarged view. The stapler i shown in Fig. 26A includes a rotation restricting mechanism 9 for the driving arm, and 'limits the rotation of the arm 5 of the driving arm 3 when the handle is opened. Here, the opening of the handle means that the arm cover 15 When the angle between the handle cover 36 and the handle cover 36 is set to the opening angle Θ2 when the handle is opened, the needle mechanism 2 on the bending arm 5 remains in the waiting position, and the drive arm 3 and the staple cover are included. Put

The handle cover 36 of the arm 6 opens the arm cover 15 to about 1 〇. ~18〇. Opening angle

The rotation restricting mechanism 9'' is constituted by the pair of projections 5k, 5m of the bending arm 5 and the pair of projections 3f, 3g of the driving arm 3. As shown in Fig. 28B, the projections 5k and 5π are provided so as to protrude inward from the lower portion at the lower left and right portions of the pivot holes 5b and 5c of the bending arm 5. X, a pair of protrusions 3f, 3g are provided above the rear end 223*7-9612-PF 40 200909153 of the drive I 3 . In this example, the projection 5 set as the bending arm 5 stands on the rotation of the projection 3 of the driving arm 3, and the projection of the f-arm 5 is located on the rotational locus of the projection 3g of the driving arm 3. When the rotation of the driving arm 3 is completed, the convex portions 3i and 5k and the protruding portion 3 are in a positional relationship, and the bending arm 5 and the driving arm 3 are assembled (see FIG. 26B). The stapler i has The arm 6' which presses the upper portion of the driving arm 3 downward does not have a handle cover 36 which is covered by the rear end portion of the driving arm 3; the arm 6 is moved from the (four) movement. In this example, the handle cover When the 36 is opened, the driver's dog 3f hits the protrusion 5k of the bending arm 5, and the dog-up portion 3g of the driving arm 3 hits the protrusion 0卩5m of the bending arm 5. In this way, the handle:: when opened 'The driving arm 3 can be engaged with the bending arm 5 in the sheet metal, and the structure of the ι can be described with reference to Fig. 27' to describe the driving arm 3 for the rotation restricting mechanism: =. Will be one of the pair of protrusions of the rotation restricting mechanism 9〇 Above the rear end portion of the driving arm 3 shown in Fig. 7, the upper portion of the hinge of the driving arm 3 shown in Fig. 27 is linearly arranged in a circular arc portion. Part 8. ° 8 The main body frame 3a, which is made of the gold plate 2 ° # 3, for example, the gold structure 1 (four), and then the plate work. At this time, in the driving arm! and the heart-shaped section [the fixed position of the glyph, Including the protrusion ❹:: on the rear end, in addition, 'becomes the drive ψ 3 parts, 3, and pulls the f member inward, and the hole for the bearing y is connected with the protrusions 3d, 2237 of the cup member. 9612-pp 41 200909153 3e. Then, for example, chrome plating or the like is applied to the entire driving arm 3, whereby the driving arm 3 having the main body frame 3a shown in Fig. 27 can be erected. Next, referring to Figs. 28A and 28B A description will be given of a structural example of a curved arm ς * 巧3. The curved arm 5 shown in Fig. 28 is a pair of protrusions ς, '5m from the left and right hole portions 5b'5c shown in Fig. 28B (hinge The lower portion of the hole protrudes inward, and the projections 5k and 5m are obtained by bending the lower portion of the curved arm 5 inward.

The bending arm 5 is, for example, formed into a main body frame 5a which is formed by drawing a curved arm into a sheet metal member, and then performing cutting processing, drilling processing, and bending into a U-shaped cross section shown in Fig. 28B. At this time, the curved arm is expanded in shape, and a pair of protrusions 5k and 5m are provided below the hole portions 5b and 5c of the main body frame 5a. The projections 5k and 5m are formed by bending the inside. Thereby, the curved arm 5 having the pair of protrusions 5k and 5m in the main body frame 5a shown in Fig. 28A and Fig. 28β can be produced. Next, an operation example of the rotation restricting mechanism 90 will be described with reference to Figs. 29A and 29B. The rotation restricting mechanism 9A shown in Fig. 29A has a pair of projections 3f, 3g provided above the rear end portion of the drive arm 3, and on one side, the projection 5k of the bending arm 5 is located at the projection 3f of the drive arm 3. On the other side, on the other side, the raised portion 5m of the curved arm 5 is placed on the rotational path of the projection 3g of the drive arm 3. For example, (7) the 'dog-up portion 5k is disposed immediately below the hole portion 5b' and is disposed at a position where the protrusion P 3f of the drive arm 3 is prevented from excessively rotating when the handle is opened. In the same way, for example, the Jiali silver land '5m is arranged directly below the hole 5c' and is disposed on the block driving arm q. The position where the protrusion 3 of the '3' is excessively rotated. 2237-9612-PF 42 200909153 In '29A ® 'to use τρ as the waiting position for the book machine ,, when 〇Ρ is used as its open position, if the waiting position is ΤΡ, the protrusion 3g (3f) of the driving arm 3 The angle between the protrusion of the curved arm 5 and the protrusion 设为 is set to an open angle and the angle of 0 2 is set to about j 7 〇. . This is used to put the handle 36 on the # cover! 5 Open opening angle 0 2 is limited to the dog opening portion 5m (5k) which does not exceed the mouth flaps #5, and is disposed in the open position 0P ° of the driving arm 3 as shown in Fig. 29B, when the handle I 36 is opened, That is, when the rotation of the drive arm 3 is completed, 'the dog portion 5 ant 5k) of the projection 3g (3f) of the drive arm 3 collides with each other on the rotation guide. At the end of the opening of the handle, the opening angle Θ2 becomes 〇. . Thereby, the opening angle 0 2 at which the handle cover is opened to the arm cover 15 can be restricted so as not to exceed j 7 。. .

Thus, the stapler of the 4 壹M κ according to the present embodiment includes a rotation restricting mechanism for restricting the excessive rotation of the driving arm 3, and the projections 5k and 5m of the bending arm 5 are formed (the inner side is curved). Part) is located at the protrusion of the handle arm 3

Therefore, when the handle cover 36 is opened, the dirty arm s "4 can open the driving arm 3 to the bending arm 5 with each other in the sheet metal, and the f ^ ^ ^ ^ #3 can be flexibly and firmly locked. The arm caps of the above-mentioned _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ In the case of sin, but not limited to this, it can also be made from the drive arm 3 to the outer I w - again, the f-curve or the nail-locking portion, etc.

2237-9612-PF 43 200909153 The projections are placed against the projections on the side of the curved arm 5 or the end faces of the plate thickness. Further, it is also possible to provide the projecting portion or the thick end portion on the driving arm 3, and to provide the protruding portion such as the stud portion to the inner side of the bending arm 5, and to abut these. Further, in this case, by providing the projections in the sheet metal member as in the present embodiment, the projections can be bent without being bent and firmly. In the present embodiment, each of the projections is provided in a pair of configurations, and the load at the time of collision is dispersed, so that it can be satisfactorily supported. Next, referring to Figure 30, the stapler is explained! The staple structure of the confirmation window is confirmed. If a long hole or a round hole such as a stapler or a folding machine is provided on the side of the needle E, it is a staple confirmation window for confirming the remaining amount of the needle, but in the visual It is difficult to confirm. " In this example, it is the work of confirming the structure of the staple portion of the staple, and the r port: confirms the remaining amount of the staple 33. It is true that the book Μ Μ == two: the book confirmation window portion 81 is set to the third. The Shushu machine shown in the picture! The needle confirming window portion 81 constitutes a long hole shape, and the sheep on the side of the actuator is swollen and the curvature on the side of the shaft supporting mechanism 70 is large. According to this m(4), when there are many remaining ,, the area of the staple can be seen from the long hole of the window, and the remaining amount of the staple is small, and the length of the staple can be seen according to the length of the window. A structural example of the part 8 of the staple 33 33 sheep. The f 3 / staple confirmation window has a long hole shape on the side of the needle (4)::; the book confirmation window 少^ is small. P 8la, the pin table confirmation window portion 81 on the side of the end portion of the needle pin 91 2237 - 9612 - Pp 44 200909153 has a large curvature on the side of the rear end portion, for example. According to the staple book, it can be seen from the window portion 81 that the remaining amount of the book needle gradually decreases, and the remaining amount of the staple pin 33 is felt. Therefore, it is possible to more clearly confirm the nail side force I: Fig.: The staple confirming window portion 82 is formed by the structure / 仏 of the ❹ 92, and the upper portion is printed with a plurality of vertical stripes (four). Between the longitudinal portions 82b, the remaining amount of the needle 33 is asked. In this example, five longitudinal stripes are imprinted from the front end portion of the needlesmith 92 toward the rear end portion side. f is set as the first to fifth vertical stripes. For example, when the position of the fifth vertical line is confirmed, the last part of the needle 33 can be confirmed, and ff can be taken, and it can be confirmed that "the remaining amount is 30". 'In the case where the last part of the staples 33 can be confirmed at the position of the 纵4 vertical line, it can be confirmed that the remaining amount is 25". The last part of the staple 33 can be confirmed at the position of the 纵3 vertical line. It is confirmed that "the remaining amount is 2", and the last part of the staple 33 can be confirmed at the position of the second vertical line, and it is confirmed that "the remaining amount is 15", and the position of the first vertical line can be confirmed. In the case of the last part of the needle 33, the "remaining amount system" can be confirmed. The staple confirming window portion 83 shown in Fig. 31C is formed by arranging a plurality of circular holes having different diameters and different diameters in the order of small to large on the side surface of the butt 93 from the front end side to the rear end side. . If it is the first round hole 8 3 a to the fourth circular hole 8 3 d ', the last part of the staple 33 can be confirmed at the position of the fourth circular hole 8 3 d, for example, the remaining amount can be confirmed. In the case where the last portion of the staples 33 can be confirmed at the position of the third circular hole 83c, it can be confirmed that "the remaining amount is about 20"" is at the position of the second circular hole 83b.

2237-9612-PF 45 200909153 When the last part of the staples 33 is confirmed, it can be confirmed that "the remaining amount is about j 5 pieces", and the last part of the staples 33 can be confirmed at the position of the first round hole 83a. It can be confirmed that "the remaining amount is about 1 〇". In the staple confirming window portion 84 shown in FIG. 31D, the long hole portion 84a is formed on the side surface of the butt 94, and a numerical value indicating the remaining amount of the staple (hereinafter referred to as a numerical portion 84b) is printed on the upper portion thereof. 〇2〇3〇』. By indicating the scale of the numerical value portion 84b or the like indicating the remaining amount of the staple, the indicator can be sensed. The setting of the staples can be confirmed by the shape of the confirmation window, and it is visually easy to know the staple confirmation window portion 8 j or the like according to the remaining amount of the stapler 1 3 3 of the present embodiment. The remaining amount of the imprinted staples of the moiré 82b, the numerical portion 84b, and the like is reduced. Therefore, the function of the staple confirming window portion 84 as an indicator can be intuitively conveyed to the user, and the staples can be visually conveyed to be gradually reduced. The above-mentioned staple confirmation window portions 81, 35 can be applied to the surface of the object without the use of a bender, and the object can be directly hit by the object. [Industrial Applicability] It is applied to a stapler including a flat bending mechanism that bends f. 〕foot.
