Abstract

A stapler used to bind paper sheets etc., having a structure capable of accurately striking a staple with a small force. Pushing down a handle causes a trigger member (10) to move a puller member (20) backward, and the movement of the puller member causes a fulcrum (B) to move backward, causing an angle formed by a fulcrum (A), the fulcrum (B), and a fulcrum (C) of a toggle mechanism to approach 180°. This causes one end of a driver spring (30) to move upward to cause force to be accumulated in the driver spring. When the handle is further pushed down to release engagement between a head end A (12) of the trigger member and a stopper (22) of the puller member, force that moves the fulcrum B disappears. This makes the fulcrum B move forward, causing the fulcrum A to lower. As a result, a blade (35) attached to the one end of the driver spring is lowered to strike a staple.

発明が解決しょうとする課題  Problems to be solved by the invention
[0003] 用紙等を綴じるのに用いるステープラであって、ハンドルに与える力が小さいにもか かわらず的確に針を打つことができるステープラを得ること、ハンドルに与える小さ ヽ にもかかわらず大きな力で針を打つことができるステープラを得ることを課題とする。  [0003] It is a stapler used for binding paper or the like, and obtains a stapler that can strike the needle accurately even though the force applied to the handle is small. The objective is to obtain a stapler that can be used to strike a needle.
[0004] また、部品点数が少なく構造が単純であるステープラを得ることを課題とする。  [0004] Another object is to obtain a stapler with a small number of parts and a simple structure.
[0005] また、針が強い力で飛び出す結果、針交換の際に針が誤って飛び出すといった事 故が生じないようなステープラを得ることを課題とする。すなわち、針交換の際には、 針を押し出す機構が機能しないような構造のステープラを得ることを課題とする。  [0005] It is another object of the present invention to obtain a stapler that does not cause the needle to jump out accidentally when the needle is replaced as a result of the needle jumping out with a strong force. That is, it is an object to obtain a stapler having such a structure that the mechanism for pushing out the needle does not function when replacing the needle.
[0006] 用紙等を綴じるのに用いるステープラにおいて、ハンドルに与える力が小さいにも かかわらず的確に針を打つことができるようにする、という課題は、常に求められてき た。これまでに、そのような課題を解決させるための機構として多くの先行技術が開 示されている。  [0006] In a stapler used for binding paper or the like, there has always been a problem of being able to accurately strike the needle even though the force applied to the handle is small. Up to now, many prior arts have been disclosed as mechanisms for solving such problems.
[0007] いわゆるタッカー式のステープラであって、小さな力で針を打つことができるステー プラとして、 USP6, 145, 728に記載のもの力 Sある。し力し、 USP6, 145, 728に記 載のステープラにあっては、針補充の際に、ステーブルがフィーダによって押圧され た状態でベースを開く構造になっており、このために、ハンドルの下降によってステー プルが突出する可能性があって非常に危険であった。また、 USP6, 145, 728よりも 大きな力で針を打つことができれば、綴じる対象の枚数を増やすことができる点で優 れている。  [0007] A so-called Tucker-type stapler that can strike a needle with a small force is the force S described in USP6, 145, 728. However, the stapler described in USP6, 145, 728 has a structure that opens the base while the staple is pressed by the feeder when refilling the needle. It was very dangerous because the staples could protrude by the descent. Also, if the needle can be hit with a force greater than USP6, 145, 728, it is advantageous in that the number of objects to be bound can be increased.
課題を解決するための手段 [0008] ハンドル部材と、前記ハンドル部材と後端が軸着されるフレーム部材と、前記フレー ム部材と後端が軸着されており、ガイド部材が取り付けられたベース部材と、前記ガイ ド部材とスプリングを介して結合しており、前記フレーム部材に設けたレールと係合し 前記ガイド部材を跨いで前後方向に摺動することによって、ガイドに沿って摺動する ステーブルを前方に押圧するフィーダ部材と、 Means for solving the problem [0008] A handle member, a frame member on which the handle member and the rear end are pivotally attached, a base member on which the frame member and the rear end are pivotally attached and a guide member is attached, and the guide member And is engaged with a rail provided on the frame member, and slides in the front-rear direction across the guide member, thereby pushing the stable moving forward along the guide. A feeder member;
一端にブレード部材が取り付けてあり他端が前記フレーム部材に取り付けられている ドライバスプリング部材と、一端が支点 Aであり他端が支点 Bであるジョイント aと 一端 が前記支点 Bであり他端が支点 Cであるジョイント bとからなり前記ジョイント aの他端と 前記ジョイント bの一端とが軸着するトグル機構と、前記支点 Bと一端が係合するブー ラ部材と、一端が前記ハンドル部材と軸着し他端の末端が前記プーラ部材と係合す るトリガ部材とを有し、前記ドライバスプリング部材がその一端と他端の間で前記支点 Aと係合しており、前記ハンドルが押し下げられることによって前記トリガ部材が回動 して前記プーラ部材を押し進め、前記プーラ部材が進むことによって支点 Bが移動し その結果支点 Aと支点 Cとの距離が大きくなり、それに伴って前記ドライバスプリング の一端が上方に移動して前記ドライバスプリングに力が蓄えられ、さらに前記ハンド ルが押し下げられることによって前記トリガ部材の末端と前記プーラ部材との係合が 外れ前記ドライバスプリングに蓄えられた力が一時に解放されて前記支点 Aが下降し 、前記支点 Aの下降によりドライノスプリングの一端に取り付けたブレードが下降する ことを特徴とするステープラによって課題を解決する。  A driver spring member having a blade member attached to one end and the other end attached to the frame member, a joint a having one end as a fulcrum A and the other end being a fulcrum B, and one end being the fulcrum B and the other end being A toggle mechanism that includes a joint b that is a fulcrum C, and the other end of the joint a and one end of the joint b are pivotally attached to each other; a boiler member that engages the fulcrum B and one end; A trigger member that engages with the puller member at the other end, and the driver spring member is engaged with the fulcrum A between one end and the other end, and the handle is pushed down As a result, the trigger member rotates to push the puller member forward, and the puller member advances to move the fulcrum B. As a result, the distance between the fulcrum A and the fulcrum C increases. At the same time, one end of the driver spring moves upward to accumulate force in the driver spring, and further, the handle is pushed down to disengage the end of the trigger member from the puller member. The problem is solved by a stapler characterized in that the force stored in is released at a time so that the fulcrum A is lowered, and the blade attached to one end of the dryino spring is lowered by the lowering of the fulcrum A.
[0009] ガイド部材とベース部材とが係合することによって、針を交換する際には、ベースと ガイドが一体となって開く。これにより、ハンドルが不用意に下降しステーブルが飛び 出す、という事故を防ぐことができる。  When the guide member and the base member are engaged, the base and the guide are integrally opened when the needle is exchanged. This prevents an accident that the handle is inadvertently lowered and the stable jumps out.
[0010] また、前記ハンドルが押し下げられることによって前記トリガ部材が回動して前記プ 一ラ部材を後進せしめ、前記プーラ部材が後進することによって支点 Bが後進して支 点 Aと支点 Cとの距離が大きくなることを特徴とするステープラによって課題を解決す る。この機構は、例えば、実施例 1に示されている。  [0010] Further, when the handle is pushed down, the trigger member rotates to move the puller member backward, and when the puller member moves backward, the fulcrum B moves backward to move the fulcrum A and the fulcrum C. The problem is solved by a stapler characterized by a large distance. This mechanism is shown, for example, in Example 1.
[0011] また、支点 Bが、常に、支点 Aと支点 Cを結ぶ線よりも前方に位置することを特徴と するステープラによって課題を解決する。 [0012] 支点 Bが、常に、支点 Aと支点 Cを結ぶ線よりも前方に位置するとは、すなわトグル 機構が図 3から図 12に示すような、後方に向けて開いた横向きの V字を描く状態をい う。このような構成となることにより、ステープラは、打針後に、打針前の状態に戻るこ とがでさる。 [0011] Further, the problem is solved by a stapler characterized in that the fulcrum B is always located in front of the line connecting the fulcrum A and the fulcrum C. [0012] The fact that the fulcrum B is always located in front of the line connecting the fulcrum A and the fulcrum C means that the toggle mechanism is a V-shaped sideways that opens backward as shown in Figs. The state of drawing. With this configuration, the stapler can return to the state before hitting after hitting.
[0013] また、前記トリガ部材の他端の、前記末端よりも前方に下方突端が備えてあり、前記 トリガ部材の末端と前記プーラ部材との係合が外れた後も前記トリガ部材の前記下方 突端と前記プーラ部材とが引き続き係合しており、前記ハンドルを押し下げる力が消 滅することにより、前記ハンドルの前方が上昇し、前記ハンドルの前方が上昇するの に伴って、前記トリガ部材の一端を軸に前記トリガ部材が回動して前記トリガ部材の 他端が下降し、前記トリガ部材の他端の下降に伴って、前記トリガ部材と前記プーラ 部材との係合位置が前方に移動し、前記トリガ部材の末端と前記プーラ部材とが再 び係合することを特徴とするステープラによって課題を解決する。  [0013] Further, the lower end of the trigger member is provided with a lower protrusion forward of the end, and the lower end of the trigger member is disengaged from the end of the trigger member and the puller member. The protrusion and the puller member are continuously engaged, and the force that pushes down the handle is extinguished so that the front of the handle rises and the front of the handle rises. The trigger member rotates about the axis and the other end of the trigger member descends, and the engagement position between the trigger member and the puller member moves forward as the other end of the trigger member descends. The problem is solved by a stapler characterized in that the end of the trigger member and the puller member are engaged again.
[0014] トリガ部材の「他端」の語はトリガ部材の「一端」に対する語として用いて 、る。すな わちトリガ部材の 2つの端部のうち、ハンドルに軸着されていない側である。「下方端」 とは、トリガ部材を図 11に示すような状態で特定する場合の下方に位置する端部を 示す。実施例では符号 13に示す部位が下方端に相当する。  The term “other end” of the trigger member is used as a term for “one end” of the trigger member. In other words, the two ends of the trigger member are the sides that are not attached to the handle. The “lower end” indicates an end portion located below when the trigger member is specified in the state shown in FIG. In the embodiment, the part indicated by reference numeral 13 corresponds to the lower end.
[0015] また、前記ハンドルが押し下げられることによって前記トリガ部材が回動して前記プ 一ラ部材を前進せしめ、前記プーラ部材が前進することによって支点 Bが前進して支 点 Aと支点 Cとの距離が大きくなることを特徴とするステープラによって、課題を解決 する。この機構は、例えば、実施例 2に示されている。  Further, when the handle is pushed down, the trigger member rotates to advance the puller member, and when the puller member moves forward, the fulcrum B advances and the fulcrum A and the fulcrum C The problem is solved by a stapler that is characterized by an increased distance. This mechanism is illustrated, for example, in Example 2.
[0016] また、支点 Bが、常に、支点 Aと支点 Cを結ぶ線よりも後方に位置することを特徴と するステープラによって、課題を解決する。  [0016] The problem is solved by a stapler characterized in that the fulcrum B is always located behind the line connecting the fulcrum A and the fulcrum C.
[0017] 支点 Bが、常に、支点 Aと支点 Cを結ぶ線よりも後方に位置するとは、すなわち、トグ ル機構が図 14〜図 16に示すような、前方に向けて開いた横向きの V字を描く状態を いう。このような構成をなることにより、ステープラは、打針後に、打針前の状態に戻る ことができる。  [0017] The fact that the fulcrum B is always located behind the line connecting the fulcrum A and the fulcrum C means that the toggle mechanism has a lateral V that opens forward as shown in Figs. The state of drawing a character. With such a configuration, the stapler can return to the state before hitting after the hitting.
[0018] 前記トリガ部材の他端の、前記末端よりも後方に下方突端が備えてあり、前記トリガ 部材の末端と前記プーラ部材との係合が外れた後も前記トリガ部材の前記下方突端 と前記プーラ部材とが引き続き係合しており、前記ハンドルを押し下げる力が消滅す ることにより、前記ハンドルの前方が上昇し、前記ハンドルの前方が上昇するのに伴 つて、前記トリガ部材の一端を軸に前記トリガ部材が回動して前記トリガ部材の他端 が下降し、前記トリガ部材の他端の下降に伴って、前記トリガ部材と前記プーラ部材 との係合位置が前方に移動し、前記トリガ部材の末端と前記プーラ部材とが再び係 合することを特徴とするステープラによって、課題を解決する。 [0018] A lower protruding end is provided at the other end of the trigger member behind the end, and the lower protruding end of the trigger member is disengaged even after the end of the trigger member is disengaged from the puller member. And the puller member are continuously engaged, and the force to push down the handle disappears, so that the front of the handle rises and the front of the handle rises. The trigger member rotates about the axis and the other end of the trigger member descends, and the engagement position between the trigger member and the puller member moves forward as the other end of the trigger member descends. The problem is solved by a stapler in which the end of the trigger member and the puller member are engaged again.

[0026] 図 2及び図 3を参照して、ドライバスプリング(30)の後方部分がフレーム (4)に固着 [0026] Referring to FIGS. 2 and 3, the rear part of the driver spring (30) is fixed to the frame (4).
(図ではねじ止め)されている。ドライノスプリング(30)は、橈る素材で構成されており 、板パネとして機能する。ドライバスプリング (30)の前方突起(32)がブレード (35)の ブレード孔(36)と係合し、ブレードの上方のブレード係合(37)がドライバスプリング の前方突起(32)と係合することにより、ブレード(35)はドライバスプリング力 外れ難 いようになっている。  (It is screwed in the figure). The dryino spring (30) is made of a material that can be beaten and functions as a panel panel. The front protrusion (32) of the driver spring (30) engages with the blade hole (36) of the blade (35), and the blade engagement (37) above the blade engages with the front protrusion (32) of the driver spring. This prevents the blade (35) from coming off the driver spring force.
[0027] ドライバスプリング(30)の上方突起(31)には、トグル機構(50)が軸着されている。  A toggle mechanism (50) is pivotally attached to the upper protrusion (31) of the driver spring (30).

Has been. A puller (20) is attached to the toggle shaft (54). The puller (20) has a stopper (22) on its upper surface.
[0028] ハンドル(3)の内壁にトリガ(10)が軸着されている。トリガ(10)はハンドル(3)と軸 着する基部(11)、作動によりプーラ(20)のストツバ(22)と係合する突端 A (12)、お よび作動によりプーラ(20)の上面と係合する突端 B (13)を有する。トリガ(10)の上 面とハンドル(3)の内壁の間にはトーシヨンパネ(図示せず)が設けてある。トーシヨン パネによって、トリガ(10)とハンドル (3)が離れる方向に力が働 ヽて 、る。  [0028] A trigger (10) is attached to the inner wall of the handle (3). The trigger (10) has a base (11) that is pivotally attached to the handle (3), a protruding end A (12) that engages with the stagger (22) of the puller (20) by operation, and an upper surface of the puller (20) by operation. Has engaging tip B (13). A torsion panel (not shown) is provided between the upper surface of the trigger (10) and the inner wall of the handle (3). The torsion panel applies a force in the direction away from the trigger (10) and the handle (3).
[0029] 図 3から図 11にステーブルの作用を示す。図 3は、作用開始前の状態である。図 4 はハンドルを矢印 Aの方向に押し下げた状態でありトリガ(10)の先端の突端 A(12) がプーラ(20)の上面を後方に少し摺り動き、突端 A(12)がプーラ(20)のストツバ(2 2)と係合するに至っている。その後、ハンドル(3)を矢印 Aの方向にさらに押し下げ ることにより、トリガの先端の突端 Aがストツバ(22)を、すなわちプーラ(20)を後方に 押す。プーラ(20)の側壁は、フレームの孔(77) (図 13)を摺動する。図 5では、ハン ドルを押し下げることによりトリガの基部(11)とフレームの垂直距離が 5mm接近した ときのプーラ(20)の状態、図 6では同距離が 10mm接近したときの状態、図 7では同 距離が 15mm接近したときの状態、図 8では同距離が 20mm接近したときの状態、 図 9では同距離が 25mm接近したときの状態、図 10では同距離が 30mm接近したと きの状態を示す。トリガ(10)の突端 A (12)がプーラ(20)のストツバ(22)を後方に押 し下げるのに対応して、プーラ(20)の基部(21)がトグルシャフト(54)を後方に導き、 その結果、くの字型に折れ曲がつていたトグル機構の折れ曲がりが伸びていく。トグ ル機構の折れ曲がりが伸びるのに対応してトグルドライバスプリングシャフト(53)が上 方に移動する。トグルドライバスプリングシャフト(53)が上方に移動するのに伴ってド ライノスプリング(30)の前方が上昇し、これに伴ってブレード(35)が上方に移動す る。ブレード(35)は、ステープル 1個分の厚さなので、ブレード(35)が上方に移動し たことによってステーブル(38)がフィーダ (40)による押圧で、一個分、前進する。 [0029] FIGS. 3 to 11 show the action of the stable. Fig. 3 shows the state before the start of action. Fig. 4 shows the handle pushed down in the direction of arrow A. The tip A (12) at the tip of the trigger (10) slid slightly back on the upper surface of the puller (20), and the tip A (12) moved toward the puller (20 ) And the stagger (22). After that, by further pushing down the handle (3) in the direction of arrow A, the protrusion A at the tip of the trigger moves the stagger (22), that is, puller (20) backward. Push. The side wall of the puller (20) slides through the hole (77) in the frame (Fig. 13). Figure 5 shows the state of the puller (20) when the vertical distance between the trigger base (11) and the frame approaches 5mm by pushing down the handle. Figure 6 shows the state when the distance approaches 10mm. Figure 8 shows the condition when the distance is 15mm, Figure 8 shows the condition when the distance is 20mm, Figure 9 shows the condition when the distance is 25mm, and Figure 10 shows the condition when the distance is 30mm. Show. The base (21) of the puller (20) moves the toggle shaft (54) backwards in response to the tip A (12) of the trigger (10) pushing down the stagger (22) of the puller (20) backwards. As a result, the folding of the toggle mechanism, which was bent in the shape of a square, is extended. The toggle driver spring shaft (53) moves upward in response to the bending of the toggle mechanism extending. As the toggle driver spring shaft (53) moves upward, the front of the draino spring (30) rises, and as a result, the blade (35) moves upward. Since the blade (35) is as thick as one staple, when the blade (35) moves upward, the stable (38) moves forward by one press by the feeder (40).
[0030] 図 8に示す状態のときに、トリガ(10)の突端 B (13)がプーラ(20)の上面と係合し、 ハンドル (3)をさらに押し下げることによってトリガ(10)の突端 A(12)は突端 B (13) を支点として持ち上がる方向に移動し(図 8、図 9、図 10)、図 10に示す状態の直後 に突端 A (12)とストッパ(22)との係合がはずれる。トリガ(10)とストッパ(22)の係合 が外れたことによりプーラ(20)は前進してドライノスプリング(30)の前方が撥ね落ち る。これによつて、ドライノスプリング(30)の前方と係合するブレード(35)が、強い力 でステーブル(38)を一個押し出し、打針が完了する。このときの、ドライバスプリング (30)に蓄えられている力は、ハンドルを押し下げる力に基づくものである力 その大 きさは、トグル機構によってハンドルを押し下げる力よりも数倍大きくなつている。  [0030] In the state shown in FIG. 8, the tip B (13) of the trigger (10) engages the upper surface of the puller (20), and the handle (3) is further pushed down to push the tip A of the trigger (10). (12) moves in the direction of lifting with the tip B (13) as a fulcrum (Figs. 8, 9, and 10). Immediately after the state shown in Fig. 10, the tip A (12) engages with the stopper (22). Will come off. When the engagement between the trigger (10) and the stopper (22) is disengaged, the puller (20) moves forward and the front of the dryino spring (30) falls off. As a result, the blade (35) engaged with the front of the dryino spring (30) pushes out one stable (38) with a strong force, and the hitting is completed. The force stored in the driver spring (30) at this time is based on the force that pushes down the handle. The magnitude of the force is several times larger than the force that pushes down the handle by the toggle mechanism.
[0031] その後、ハンドルを矢印 Aの方向に押し下げるのをやめることにより、トーシヨンパネ  [0031] After that, by pressing down the handle in the direction of arrow A, the torsion panel
(図示せず)とスプリング(図示せず)によって、ステープラは作用前の状態(図 3)に戻 る。このとき、前記の通り、これまでノヽンドルを押し下げることによりトグルのトグルドライ バスプリングシャフト(53)が上昇し、くの字型の折れ曲がりは伸びていくが、折れ曲 力 Sりが伸びきる前にトリガがプーラを後進させる力が働かなくなるので、その時点での くの字の角度は、後方が 180度より小さくなるようになつている。すなわち、くの字の折 れ曲がる方向は維持されている。このことにより、ドライバスプリング(30)が下降する ことによってトグルドライバスプリングシャフトが下降する際にプーラ(20)は「前進」す ることができ、ステープラは初めの状態に戻るのである。 (Not shown) and spring (not shown) return the stapler to its pre-action state (Figure 3). At this time, as described above, the toggle driver spring shaft (53) of the toggle is lifted by pushing down the needle until now, and the bent portion of the U-shape is extended, but before the bending force S is fully extended. Since the trigger does not apply the force to move the puller backward, the angle of the character at that point is such that the backward angle is smaller than 180 degrees. In other words, The direction of bending is maintained. This allows the puller (20) to “advance” when the toggle driver spring shaft is lowered by the lowering of the driver spring (30), and the stapler returns to its initial state.
[0032] 図 12に、ステープラ 1の針を補充する場合の作用を示す。針を補充する際には、ベ ース(2)とガイド (45)を、フレーム (4)との軸着部分を軸に回動せしめて開く。このと き、フィーダ (40)のフィーダ スプリング係合具 (41)とガイド (45)のガイドースプリン グ係合具 (46)とがスプリングで結ばれて 、るため(図示せず)、ガイド (45)がフレー ム (4)から離れるのに伴って、スプリングによってフィーダ (40)が後方に移動する。こ れにより、使い残したステーブルがあった場合にあっても、またステーブルを装填する 最中においても、万が一ハンドルが下降した場合にステーブルが飛び出すことはな い。 FIG. 12 shows the operation when the staple of the stapler 1 is replenished. When replenishing the needle, open the base (2) and guide (45) by rotating the shaft (4) with the frame (4). At this time, the feeder spring engaging member (41) of the feeder (40) and the guide spring engaging member (46) of the guide (45) are connected by a spring (not shown), so that the guide ( As 45) moves away from the frame (4), the feeder (40) is moved backward by the spring. This prevents the stable from popping out if the handle is lowered even if there is a remaining stable or during loading of the stable.
[0033] 図 13〜図 16に実施例 2を示す。実施例 1では、プーラ一が後進してトグル機構の 中央部を後方に引くことによりトグル機構を介してドライバースプリングに力が蓄えら れたのに対し、実施例 2では、プッシヤーが前進してトグル機構の中央部を前方に押 すことによりトグル機構を介してドライバースプリングに力が蓄えられる構造になって いる。その他の点については、概略的に、実施例 1と実施例 2に相違点はない。  [0033] Example 13 is shown in Figs. In Example 1, the puller moves backward and pulls the central part of the toggle mechanism backward, so that force is stored in the driver spring via the toggle mechanism, whereas in Example 2, the pusher moves forward. By pushing the center of the toggle mechanism forward, the force is stored in the driver spring via the toggle mechanism. In other respects, there is generally no difference between Example 1 and Example 2.

As a result, the toggle mechanism bent in the shape of a dogleg before the start of the action extends in a direction in which the bending is eliminated by the pusher (60) pressing the center portion forward. In response to this, the toggle driver spring shaft (53) moves upward. As the toggle driver spring shaft (53) moves upward, the front of the driver spring (30) rises, and as a result, the blade (35) moves upward. Since the blade (35) is as thick as one staple, the staple (38) is advanced by one by the pressing by the feeder (40) when the blade (35) moves upward. [0040] Immediately after the state shown in FIG. 15, the engagement between the tip A (72) and the stopper (62) is released. When the engagement between the trigger (70) and the stopper (62) is disengaged, the pusher (60) moves backward and the front of the driver spring (30) falls off. As a result, the blade (35) engaged with the front of the driver spring (30) pushes out one stable (38) with a strong force, and the hitting is completed. The force stored in the driver spring (30) at this time is based on the force that pushes down the handle. The magnitude of the force is several times larger than the force that pushes down the handle by the toggle mechanism.
[0041] その後、ハンドルを矢印 Aの方向に押し下げるのを止めることにより、トーシヨンパネ  [0041] After that, by pushing down the handle in the direction of arrow A, the torsion panel is stopped.
(図示せず)とスプリング(図示せず)によって、ステープラは初めの状態(図 14)に戻 る。このとき、前記の通り、これまでノヽンドルを押し下げることによりトグルのトグルドライ バスプリングシャフト(53)が上昇し、くの字型の折れ曲がりは伸びていくが、折れ曲 力 Sりが伸びきる前にトリガがプッシヤーを前進させる力が働かなくなるので、その時点 でのくの字の角度は、前方が 180度より小さくなるようになつている。すなわち、くの字 の折れ曲がる方向は維持されている。このことにより、ドライノスプリング(30)が下降 することによってトグルドライバスプリングシャフトが下降する際にプッシヤー(60)は「 後進」することができ、ステープラは初めの状態に戻るのである。  (Not shown) and spring (not shown) return the stapler to its initial state (Figure 14). At this time, as described above, the toggle driver spring shaft (53) of the toggle is raised by pushing down the needle until now, and the bent portion of the dogleg-shaped portion extends, but before the bending force S is fully extended. Since the trigger does not apply the force to advance the pusher, the angle of the square at that point is such that the front is smaller than 180 degrees. In other words, the direction in which the K-shape is bent is maintained. This allows the pusher (60) to “reverse” when the toggle driver spring shaft is lowered by the lowering of the dryno spring (30), and the stapler returns to the initial state.
