すなわち、開閉部材４０の弾性により、第１の作動片３０は、綴杆係止部５０を外す方向（Ｏ₁方向）に移動し、第２の作動片３２は、綴杆係止部５０を外す方向（Ｏ₂方向）に移動する。 Then, due to the elasticity of the opening / closing member 40, the first operating piece 30 and the second operating piece 32 constituting the operating member 18 start to open the first binding rod 12 and the second binding rod 14 by hand. That is, when the first binding rod 12 and the second binding rod 14 are removed from the binding hook locking portions 50, the half split rod 12a and the half split rod 12b of the first binding rod 12 are separated from each other. (Half crack 12a is in the O ₁ direction, half crack 12b is in the O ₂ direction (shown in FIG. 13) and the direction in which the half crack 14a and the half crack 14b of the second binding 14 are separated (half split) The collar 14a moves in the O ₁ direction, and the half-cotton 14b moves in the O ₂ direction (shown in FIG. 13). The twisted opening / closing member 40 tries to return to the original state. The split 12b and the half split 14a and the half split 14b are connected in the circumferential direction of the winding portion 44 (half split 12a and half split 1 a is O ₃ directions, half rod 12b and half rod 14b acts to detach the O ₄ directions).
That is, the elasticity of the opening and closing member 40, the first operating piece 30 moves in a direction (O ₁ direction) disengaging the binding rod latching portion 50, the second operating piece 32, the binding rod latching portion 50 Move in the direction to remove (O ₂ direction).

そして、開閉部材４０の弾性により、作動部材１８を構成する第１の作動片３０と第２の作動片３２は、谷折り状態から徐々に平面状態となり、そして平面状態から山折り状態に変わる。
そして、開閉部材４０は、第１の綴杆１２と第２の綴杆１４とを開いた状態にしたとき、第１の作動片３０の突き合わせ縁３０ａと第２の作動片３２の突き合わせ縁３２ａとが山折り状態、すなわち、保持部材１６の被綴じ物載置部２２の内側面に近づいた状態に保持するように作用する。 Then, due to the elasticity of the opening / closing member 40, the first operating piece 30 and the second operating piece 32 constituting the operating member 18 gradually change from the valley folded state to the planar state, and change from the planar state to the mountain folded state.
The opening / closing member 40 has the butting edge 30a of the first working piece 30 and the butting edge 32a of the second working piece 32 when the first binding rod 12 and the second binding rod 14 are opened. Acts to be held in a mountain-folded state, that is, in a state of approaching the inner surface of the binding object mounting portion 22 of the holding member 16.

保持部材１６の被綴じ物載置部２２には、係合部３０ｄ及び３２ｅとが上側に向いて回転したときに被綴じ物載置部２２の内面と当接しないようにするための膨出部２２ａが長手方向に延びて形成され、係合部３０ｅ及び３２ｄとが上側に向いて回転したときに被綴じ物載置部２２の内面と当接しないようにするための膨出部２２ｂが長手方向に延びて形成されている。
また、保持部材１６の被綴じ物載置部２２には、開閉部材４０が上側に向いて移動したときに被綴じ物載置部２２の内面と当接しないようにするための膨出部２２ｃが長手方向に延びて形成されている。 The swelled object mounting portion 22 of the holding member 16 bulges so as not to come into contact with the inner surface of the bound object mounting portion 22 when the engaging portions 30d and 32e rotate upward. A bulging portion 22b is formed so that the portion 22a extends in the longitudinal direction and prevents the engagement portions 30e and 32d from contacting the inner surface of the binding object mounting portion 22 when the engagement portions 30e and 32d rotate upward. It extends in the longitudinal direction.
Further, the binding object mounting portion 22 of the holding member 16 has a bulging portion 22c for preventing the opening / closing member 40 from coming into contact with the inner surface of the binding object mounting portion 22 when the opening / closing member 40 moves upward. Is formed extending in the longitudinal direction.

第１の綴杆１２は、略円環状の綴杆となるように、半円弧状の半割杆１２ａと半割杆１２ｂとから構成され、第２の綴杆１４は、略円環状の綴杆となるように、半円弧状の半割杆１４ａと半割杆１４ｂとから構成されている。そして、被綴じ物Ｐに予め穿設された綴じ孔に挿通して、被綴じ物Ｐを綴じることができるように、半割杆１２ａおよび半割杆１２ｂと、半割杆１４ａと半割杆１４ｂの先端、すなわち第１の綴杆１２および第２の綴杆１４の頂部において、綴杆係止部５０が形成されている。
第１の綴杆１２を構成する半割杆１２ａと半割杆１２ｂとは、半割杆１２ａの綴杆係止部５０と、半割杆１２ｂの綴杆係止部５０とを係止することにより、環状に連結される。
また、第２の綴杆１４を構成する半割杆１４ａと半割杆１４ｂとは、半割杆１４ａの綴杆係止部５０と半割杆１４ｂの綴杆係止部５０とを係止することにより、環状に連結される。 The first binding rod 12 is composed of a semicircular arc-shaped half split rod 12a and a half split rod 12b so as to be a substantially annular binding rod, and the second binding rod 14 is a substantially annular binding rod. It is comprised from the semicircular arc shaped half split rod 14a and the half split rod 14b so that it may become a kite. Then, the half split bar 12a, the half split bar 12b, the half split bar 14a, and the half split bar so that the binding target P can be bound by being inserted into a binding hole previously drilled in the binding target P. At the tip end of 14b, that is, at the tops of the first binding rod 12 and the second binding rod 14, a binding binding portion 50 is formed.
The half split bar 12a and the half split bar 12b constituting the first binding bar 12 lock the binding bar locking part 50 of the half split bar 12a and the binding bar locking part 50 of the half split bar 12b. Thus, they are connected in a ring shape.
Further, the half split bar 14a and the half split bar 14b constituting the second binding bar 14 lock the binding bar locking part 50 of the half split bar 14a and the binding bar locking part 50 of the half split bar 14b. By doing so, they are connected in a ring shape.

前記綴杆を構成する第１の綴杆１２及び第２の綴杆１４は、断面円形状金属製線材を、綴杆係止部５０を外す方向（図１３のＯ₁及びＯ₂の方向）にのばし、且つ中央部分を押さえることによって綴杆を閉じる方向に対してわん曲させて形成されている。そして、第１の綴杆１２及び第２の綴杆１４は、中央が綴杆を開く方向（半割杆１２ａ及び半割杆１４ａは、図１３のＯ₃方向、半割杆１２ｂ及び半割杆１４ｂは、図１３のＯ₄方向）に膨み且つ両端が綴杆を閉じる方向にわん曲した断面略空豆（ビーンズ）型の形状に形成されている。
すなわち、環状の第１の綴杆１２及び第２の綴杆１４を開閉方向に見て、第１の綴杆１２及び第２の綴杆１４の内側は波状起伏面が形成され、第１の綴杆１２及び第２の綴杆１４の外側は半円弧状に形成されている。そして、第１の綴杆１２及び第２の綴杆１４は、綴杆を外す方向に見て、両外側が、半円弧状に形成されている。
従来の断面形状丸型の綴杆は、小径だと変形に弱く、大径にすれば断面積が増して材料費がかさみ、従来の断面形状略長方形の綴杆は、用紙にあける綴じ穴には丸穴が多いので、用紙の綴じ穴に対応しにくく、用紙の綴じ穴を傷つけるおそれがある。
ところが、綴杆を構成する第１の綴杆１２及び第２の綴杆１４は、細いならば綴杆係止部５０の嵌合がうまくゆかないときがある。
そのために、第１の綴杆１２及び第２の綴杆１４の幅を広げたいが、元の線材として断面積の小さいものを使用しても、元の金属製線材を加工することにより綴杆としては必要な幅が確保されるようにしたい。
そこで、本願発明にかかる綴杆は、それを形成する線材の中央部分を押さえて線材を空豆（ビーンズ）型につぶすことにより全体としての幅を広げ、すなわち、綴杆の全体の幅を綴杆係止部５０を外す方向に広げて、綴杆係止部５０の嵌合を完全にできるように形成している。 The first binding rod 12 and the second binding rod 14 constituting the binding rod are directions in which the binding wire locking portion 50 is removed from the circular cross-section metal wire (directions O ₁ and O _{2 in} FIG. 13). It is formed to bend with respect to the direction in which the binding is closed by extending and holding down the central portion. The first binding rod 12 and the second binding rod 14 are in the direction in which the center opens the binding rod (the half split rod 12a and the half split rod 14a are the O ₃ direction, half split rod 12b and half split in FIG. rod 14b is bulging and both ends are formed in the shape of a substantially broad beans (beans) type in which curved in a direction of closing the binding rods in O ₄ direction) in FIG. 13.
That is, when the annular first binding rod 12 and the second binding rod 14 are viewed in the opening / closing direction, a wavy undulating surface is formed inside the first binding rod 12 and the second binding rod 14, The outer sides of the binding rod 12 and the second binding rod 14 are formed in a semicircular arc shape. And the 1st binding rod 12 and the 2nd binding rod 14 are formed in the semicircular arc shape on both outer sides seeing in the direction which removes a binding staple.
Conventional cross-section round staples are less susceptible to deformation if they have a small diameter, and if the diameter is large, the cross-sectional area increases and material costs increase. Since there are many round holes, it is difficult to correspond to the binding holes of the paper, and there is a risk of damaging the binding holes of the paper.
However, if the first binding rod 12 and the second binding rod 14 constituting the binding rod are thin, the binding of the binding rod locking portion 50 may not be successful.
Therefore, although it is desired to increase the width of the first binding rod 12 and the second binding rod 14, even if the original wire rod having a small cross-sectional area is used, the binding rod can be obtained by processing the original metal wire rod. I want to ensure the necessary width.
Therefore, the binding rod according to the present invention increases the overall width by pressing the central portion of the wire rod forming the wire rod and crushing the wire rod into a bean shape. The locking portion 50 is widened in the direction to remove it, and is formed so that the binding of the binding lock portion 50 can be completed completely.

第１の綴杆１２と第２の綴杆１４とは、それぞれの基部が第１の作動片３０と第２の作動片３２に固着された部分（４箇所）を通る左右軸Ｙ₁，Ｙ₂および前後軸Ｘ₁，Ｘ₂（第１３図図示）を含む平面Ｐ_XYと垂直な平面を構成するように、第１の作動片３０と第２の作動片３２より立設されている。そして、第１の綴杆１２の軸Ｚ₁（第１３図図示）が構成する円形面と第２の綴杆１４の軸Ｚ₂（第１３図図示）が構成する円形面とは、平行で、且つ、第１の綴杆１２と第２の綴杆１４が第１の作動片３０と第２の作動片３２と固着された部位を通る平面Ｐ_XYと垂直となるように構成されている。 The first binding rod 12 and the second binding rod 14 have left and right axes Y ₁ and Y passing through portions (four locations) where the respective base portions are fixed to the first working piece 30 and the second working piece 32. ₂ and the first working piece 30 and the second working piece 32 so as to form a plane perpendicular to the plane P _XY including the front and rear axes X ₁ and X ₂ (shown in FIG. 13). The circular surface formed by the axis Z ₁ (shown in FIG. 13) of the first binding rod 12 and the circular surface formed by the axis Z ₂ (shown in FIG. 13) of the second binding rod 14 are parallel to each other. and, the first binding rod 12 and the second binding rod 14 are configured such that the first operating piece 30 and the plane P _XY perpendicular through the anchored portion and the second operating piece 32 .

綴杆を閉じるとき、第１の作動片３０及び第２の作動片３２は、山折り状態（図２１参照）から徐々に平面状態（中立状態）となり、更に平面状態（中立状態）から谷折り状態（図１６参照）に変わるとともに、同列に並んだ状態から、一旦綴杆係止部５０の外れる方向（第１の作動片３０はＯ₁方向、第２の作動片３２はＯ₂方向）に移動して、たがいちがいに並んだ状態となり（図１７参照）、その後逆戻りして同列に並ぶ。
それによって、移動規制部を構成する第１の作動片３０の規制凸起３０ｇが第２の作動片３２の規制凹部３２ｆ内を移動して、規制凹部３２ｆにおける綴杆係止部５０の外れる方向とは反対側の端縁に当接し、且つ移動規制部を構成する第２の作動片３２の規制凸起３２ｇが第１の作動片３０の規制凹部３０ｆ内を移動して、規制凹部３０ｆにおける綴杆係止部５０の外れる方向とは反対側の端縁に当接する（図１７参照）。 When closing the binding, the first working piece 30 and the second working piece 32 gradually change from the mountain-folded state (see FIG. 21) to the flat state (neutral state), and further from the flat state (neutral state) to the valley fold. The state (see FIG. 16) is changed, and from the state of being arranged in the same row, the direction in which the binding lock portion 50 is once removed (the first operating piece 30 is in the O ₁ direction, the second operating piece 32 is in the O ₂ direction). To the state where they are lined up in a line (see FIG. 17), and then go back and line up in the same row.
Thereby, the restriction protrusion 30g of the first operating piece 30 constituting the movement restricting portion moves in the restricting recess 32f of the second actuating piece 32, and the binding lock portion 50 is released from the restricting recess 32f. The regulating protrusion 32g of the second operating piece 32 that contacts the edge opposite to the side and that constitutes the movement restricting portion moves in the restricting recess 30f of the first operating piece 30, and in the restricting recess 30f. It abuts on the edge opposite to the direction in which the binding lock 50 is removed (see FIG. 17).

そして、第１の綴杆１２と第２の綴杆１４とは、同一方向に向けて、その綴杆係止部５０を指で外すことができるように構成されている。
第１の綴杆１２を構成する半割杆１２ａの先端に形成された綴杆係止部５０を構成する先端の凸部５２ａ及びその凸部５２ａに続く凹部５２ｂと、半割杆１２ｂの綴杆係止部５０を構成する先端の凸部５４ａ及びその先端の凸部５４ａに続く凹部５４ｂとは、第１の綴杆１２を閉じたとき係合するように逆方向に向けて突き出しあるいは凹み形成されている。凸部５２ａと凸部５４ａとは、それぞれ先端から内側に向けて傾斜縁を備えており、すべりながら、第１の綴杆１２および第２の綴杆１４を開閉することができるように形成されている。
また、第２の綴杆１４を構成する半割杆１４ａの先端に形成された綴杆係止部５０を構成する凸部５６ａ及びその凸部５６ａに続く凹部５６ｂと、半割杆１４ｂの綴杆係止部５０を構成する先端の凸部５８ａ及びその先端の凸部５８ａに続く凹部５８ｂとは、第２の綴杆１４を閉じたとき係合するように逆方向に向けて突き出しあるいは凹み形成されている。
また、半割杆１２ａの綴杆係止部５０を構成する凸部５２ａと半割杆１４ａの綴杆係止部５０を構成する凸部５６ａとは、同一方向に向けて突き出し設けられている。

A convex portion 52a at the distal end constituting the binding rod locking portion 50 formed at the distal end of the half split rod 12a constituting the first binding rod 12, a concave portion 52b following the convex portion 52a, and a binding of the half split rod 12b The protrusion 54a at the tip constituting the hook locking portion 50 and the recess 54b following the protrusion 54a at the tip protrude or dent in the opposite direction so as to be engaged when the first staple 12 is closed. Is formed. The convex portion 52a and the convex portion 54a are each provided with an inclined edge inward from the tip, and are formed so that the first binding rod 12 and the second binding rod 14 can be opened and closed while sliding. ing.
Moreover, the convex part 56a which comprises the binding hook latching part 50 formed in the front-end | tip of the half split hook 14a which comprises the 2nd binding rod 14, the recessed part 56b following the convex part 56a, and the binding of the half split hook 14b The protrusion 58a at the tip constituting the hook locking portion 50 and the recess 58b following the protrusion 58a at the tip protrude or dent in the opposite direction so as to engage when the second binding rod 14 is closed. Is formed.
Moreover, the convex part 52a which comprises the binding hook locking part 50 of the half split hook 12a, and the convex part 56a which comprises the binding hook locking part 50 of the half split hook 14a are protruded and provided toward the same direction. .
Moreover, the recessed part 54b which comprises the binding hook locking part 50 of the half split hook 12b, and the recessed part 58b which comprises the binding hook locking part 50 of the half split hook 14b are recessedly formed toward the same direction.

したがって、第１の綴杆１２の綴杆係止部５０を、第１の綴杆１２の頂部を指でねじることにより外すことができ、第１の綴杆１２の綴杆係止部５０を指で外すと、第１の作動片３０と第２の作動片３２とが、開閉部材４０が元の状態に戻ろうとする力、すなわち一方の固定先端部４２ａと他方の固定先端部４２ｂとが平行となるように力が働くことにより第１の作動片３０と第２の作動片３２とが逆方向に移動する。すなわち、第２の綴杆１４を構成する半割杆１４ａの凸部５６ａと半割杆１４ｂの凸部５８ａとを引き離す方向に作用して、第１の綴杆１２の半割杆１２ａの凸部５２ａと半割杆１２ｂの凸部５４ａとを引き離す方向に作用するとともに、第２の綴杆１４を構成する半割杆１４ａの凸部５６ａと半割杆１４ｂの凸部５８ａとを引き離すように作用する。 Therefore, the binding lock 50 of the first binding 12 can be removed by twisting the top of the first binding 12 with a finger, and the binding locking 50 of the first binding 12 can be removed. When removed with a finger, the first working piece 30 and the second working piece 32 cause the force that the opening / closing member 40 returns to the original state, that is, one fixed tip 42a and the other fixed tip 42b. The first working piece 30 and the second working piece 32 move in opposite directions by the force acting so as to be parallel. That is, the convex portion 56a of the first binding rod 12 acts so as to separate the convex portion 56a of the half split rod 14a and the convex portion 58a of the half split rod 14b constituting the second binding rod 14.

したがって、綴杆を構成する第１の綴杆２１２及び第２の綴杆２１４の開閉時において、第１の作動片２３０及び第２の作動片２３２が突き合わせ縁２３０ａ及び突き合わせ縁２３２ａを枢軸として揺動するときにおいて、第１の作動片２３０の幅と第２の作動片２３２の幅との和が最大になったとき、すなわち、第１の作動片２３０と第２の作動片２３２とが平面状態（中立状態）になったときにおいても、第１の作動片２３０の最も外側の縁と保持部材２１６の保持壁２２４ａとの間及び第２の作動片２３２の最も外側の縁と保持部材２１６の保持壁２２４ｂとの間に適宜な間隙が生じ、保持部材２１６の保持空間内において作動部材２１８の第１の作動片２３０及び第２の作動片２３２が円滑に移動できる。 The fixed tip portion 242a and the fixed tip portion 242b have the fixed portions 246a and 246b having a fixed length, the intermediate portion 247a is the support portion 236c of the operating member 218, and the intermediate portion 247b is the support portion 238c of the operating member 218. Between the first working piece 230 and the second working piece 232 abutted at the butting edge 230a of the first working piece 230 and the butting edge 232a of the second working piece 232. The distance is kept constant, and the first working piece 230 and the second working piece 232 are pulled close to keep their positional relationship in an optimum state.
Therefore, when the first binding pin 212 and the second binding rod 214 constituting the binding rod are opened and closed, the first operating piece 230 and the second operating piece 232 swing around the butting edge 230a and the butting edge 232a as pivots. When moving, when the sum of the width of the first working piece 230 and the width of the second working piece 232 is maximized, that is, the first working piece 230 and the second working piece 232 are flat. Even when the state (neutral state) is reached, the outermost edge of the first operating piece 230 and the holding wall 224a of the holding member 216 and the outermost edge of the second operating piece 232 and the holding member 216 are arranged. An appropriate gap is generated between the first working piece 230 and the second working piece 232 of the working member 218 within the holding space of the holding member 216.

前記半割杆が組み合わされて第１の綴杆２１２及び第２の綴杆２１４が形成されているとき、前記保持部材２１６の長手方向における前記開閉部材２４０の両側の先端部間の距離（固定先端部２４２ａの係止端部２４８ａと固定先端部２４２ｂの係止端部２４８ｂとの間の距離）は、前記巻線部２４４の両端の距離と略々同一に形成されている。
そして、１対の前記第１の作動片２３０及び第２の作動片２３２は、前記保持部材２１６の長手方向において互いに逆方向に移動させることにより、前記半割杆の組み合わせによる前記第１の綴杆２１２及び第２の綴杆２１４が分離され、前記第１の綴杆２１２及び第２の綴杆２１４が分離されたときに、前記開閉部材２４０の両先端部が平面視略平行な状態から互いにやや離れる方向にわん曲した後に略平行となった状態で、前記開閉部材２４０は、前記第１の作動片２３０と第２の作動片２３２とを付勢して、前記第１の半割杆２１２ａと第２の半割杆２１２ｂ及び第３の半割杆２１４ａと第４の半割杆２１４ｂとを開放させる。 When the first binding rod 212 and the second binding rod 214 are formed by combining the half splits, the distance (fixed) between the tip portions on both sides of the opening / closing member 240 in the longitudinal direction of the holding member 216 The distance between the locking end portion 248a of the front end portion 242a and the locking end portion 248b of the fixed front end portion 242b is formed to be substantially the same as the distance between both ends of the winding portion 244.
Then, the pair of the first working piece 230 and the second working piece 232 are moved in the opposite directions in the longitudinal direction of the holding member 216, so that the first binding by the combination of the half splits is performed. When the collar 212 and the second staple 214 are separated and the first staple 212 and the second staple 214 are separated, the both ends of the opening / closing member 240 are substantially parallel to each other in plan view. The opening / closing member 240 urges the first operating piece 230 and the second operating piece 232 in a state of being substantially parallel after bending in a direction slightly away from each other, and thereby the first half. The barb 212a and the second half-barrel 212b and the third half-barrel 214a and the fourth half-barrel 214b are opened.

開閉部材固定部２３６ｂ及び開閉部材固定部２３８ｂは、直線状の突き合わせ縁２３０ａ及び突き合わせ縁２３２ａに一直線状に並ぶように、空隙部２３６ａ及び空隙部２３８ａの中央に向けて突き出され、開閉部材２４０の巻線部２４４の内側に形成された貫通孔内に挿入される太さと長さを有するように形成されている。 The opening / closing member fixing portion 236b and the opening / closing member fixing portion 238b are projected toward the center of the gap portion 236a and the gap portion 238a so as to be aligned with the straight abutting edge 230a and the abutting edge 232a. It is formed so as to have a thickness and a length to be inserted into a through hole formed inside the winding portion 244.

支持部２３６ｃ及び支持部２３８ｃは、第１の作動片２３０及び第２の作動片２３２の長手方向（第１の作動片２３０はＯ₁方向、第２の作動片２３２はＯ₂方向（図３７図示））にのびる細孔であり、固定先端部２４２ａ及び固定先端部２４２ｂを第１の作動片２３０及び第２の作動片２３２の一方主面から他方主面に向けて挿入するための挿入孔２３６ｄ及び挿入孔２３８ｄに連続して設けられている。 The support part 236c and the support part 238c are arranged in the longitudinal direction of the first working piece 230 and the second working piece 232 (the first working piece 230 is in the O ₁ direction, and the second working piece 232 is in the O ₂ direction (FIG. 37). The insertion hole for inserting the fixed tip portion 242a and the fixed tip portion 242b from one main surface of the first working piece 230 and the second working piece 232 toward the other main surface. 236d and the insertion hole 238d are provided continuously.

一方の固定先端部２４２ａと他方の固定先端部２４２ｂとは、図３３（Ａ）に示すように元々平行状態にあったが、固定先端部２４２ａ及び固定先端部２４２ｂは、第１の作動片２３０および第２の作動片２３２のそれぞれの長手方向、すなわち第１の作動片２３０の第１の半割杆２１２ａを固定する部位と第３の半割杆２１４ａを固定する部位とを結ぶ線（Ｘ₁（第３４図図示））および第２の作動片２３２の第２の半割杆２１２ｂを固定する部位と第４の半割杆２１４ｂを固定する部位とを結ぶ線（Ｘ₂（第３４図図示））と略々直交する方向に架け渡されている。
さらに、開閉部材２４０が開き始めたときは、元々ほぼ平行に接近していた固定先端部２４２ａ（特に固定部２４６ａ）と固定先端部２４２ｂ（特に固定部２４６ｂ）とは、図４１において示すようにわずかに引き離されて、固定先端部２４２ａが第２の作動片２３２に係止され且つ固定先端部２４２ｂが第１の作動片２３０に係止されてねじられた状態になる。 One fixed tip 242a and the other fixed tip 242b were originally in a parallel state as shown in FIG. 33A, but the fixed tip 242a and the fixed tip 242b are the first operating piece 230. And a line connecting the longitudinal direction of each of the second operating pieces 232, that is, the portion fixing the first half-split 212a of the first operating piece 230 and the portion fixing the third half-split 214a (X ₁ (shown in FIG. 34) and a line (X ₂ (see FIG. 34) connecting a portion for fixing the second half-split 212b of the second operating piece 232 and a portion for fixing the fourth half-split 214b. (Illustrated)).
Furthermore, when the opening / closing member 240 starts to open, the fixed tip portion 242a (particularly the fixed portion 246a) and the fixed tip portion 242b (particularly the fixed portion 246b) that were originally approaching substantially parallel are shown in FIG. The fixed tip 242a is locked to the second operating piece 232 and the fixed tip 242b is locked to the first operating piece 230 to be twisted by being slightly separated.

固定先端部２４２ａは、第２の作動片２３２の空隙部２３８ａの側から開閉部材固定部２３８ｂの下面を通り第１の作動片２３０の下面より支持部２３６ｃの上面に至るように架け渡されている。
固定先端部２４２ｂは、第１の作動片２３０の空隙部２３６ａの側から開閉部材固定部２３６ｂの下面を通り第２の作動片２３２の下面より支持部２３８ｃの上面に至るように架け渡されている。
したがって、固定先端部２４２ａは、第１の作動片２３０に装填し易く第１の作動片２３０を下面側に向けて強い力で回転して開くように機能し、固定先端部２４２ｂは、第２の作動片２３２に装填し易く第２の作動片２３２を下面側に向けて強い力で回転して開くように機能する。 The fixed distal end portion 242a is bridged from the gap portion 238a side of the second working piece 232 through the lower surface of the opening / closing member fixing portion 238b to reach the upper surface of the support portion 236c from the lower surface of the first working piece 230. Yes.
The fixed distal end portion 242b is bridged from the gap portion 236a side of the first operating piece 230 through the lower surface of the opening / closing member fixing portion 236b to reach the upper surface of the support portion 238c from the lower surface of the second operating piece 232. Yes.
Accordingly, the fixed tip 242a functions so as to be easily loaded into the first working piece 230 and to rotate and open the first working piece 230 toward the lower surface side with a strong force, and the fixed tip 242b The second operating piece 232 functions so as to be rotated and opened with a strong force toward the lower surface side.

そして、開閉部材２４０の弾性により、作動部材２１８を構成する第１の作動片２３０及び第２の作動片２３２は、第１の綴杆２１２と第２の綴杆２１４を手で開き始めたとき、すなわち、第１の綴杆２１２と第２の綴杆２１４のそれぞれの綴杆係止部２５０を外したとき、第１の綴杆２１２の第１の半割杆２１２ａと第２の半割杆２１２ｂとが離れる方向（第１の半割杆２１２ａはＯ₁方向で、第２の半割杆２１２ｂはＯ₂方向（第３４図図示））および第２の綴杆２１４の第３の半割杆２１４ａと第４の半割杆２１４ｂとが離れる方向（第３の半割杆２１４ａはＯ₁方向で、第４の半割杆２１４ｂはＯ₂方向（第３４図図示））に移動するとともに、ねじられていた開閉部材２４０が元の状態に戻ろうとして、第１の半割杆２１２ａと第２の半割杆２１２ｂとをおよび第３の半割杆２１４ａと第４の半割杆２１４ｂとを巻線部２４４の円周方向（第１の半割杆２１２ａおよび第３の半割杆２１４ａはＯ₃方向、第２の半割杆２１２ｂおよび第４の半割杆２１４ｂはＯ₄方向）に引き離すように作用する。
すなわち、開閉部材２４０の弾性により、第１の作動片２３０は、綴杆係止部２５０を外す方向（Ｏ₁方向）に移動し、第２の作動片２３２は、綴杆係止部２５０を外す方向（Ｏ₂方向）に移動する。 Then, due to the elasticity of the opening / closing member 240, the first operating piece 230 and the second operating piece 232 constituting the operating member 218 start to open the first binding pin 212 and the second binding pin 214 by hand. That is, when the first staple 212 and the second staple 214 are removed, the first half 212a and the second half of the first staple 212 are removed. The direction in which the collar 212b is separated (the first half collar 212a is in the O ₁ direction, the second half collar 212b is in the O ₂ direction (shown in FIG. 34)) and the third half of the second staple 214 The cracker 214a and the fourth half crack 214b move away from each other (the third half crack 214a is in the O ₁ direction and the fourth half crack 214b is in the O ₂ direction (shown in FIG. 34)). At the same time, the twisted opening / closing member 240 tries to return to the original state, and the first half-split 212a and the second Half rod 212b and the and the third half rod 214a and the fourth half rod 214b and a circumferential winding portion 244 (first half rod 212a and the third half rod 214a is O _three directions, the second half rod 212b and the fourth half rod 214b acts to detach the O ₄ directions).
That is, due to the elasticity of the opening / closing member 240, the first operating piece 230 moves in a direction (O ₁ direction) in which the binding hook locking portion 250 is removed, and the second operating piece 232 moves the binding hook locking portion 250. Move in the direction to remove (O ₂ direction).

そして、開閉部材２４０の弾性により、作動部材２１８を構成する第１の作動片２３０は、綴杆係止部２５０を閉じる位置の方向（Ｏ₁とは反対の方向）に移動し、且つ、第２の作動片２３２は、綴杆係止部２５０を閉じる位置の方向（Ｏ₂とは反対の方向）に移動する。
すなわち、第１の作動片２３０及び第２の作動片２３２は、谷折り状態から徐々に平面状態（中立状態）となり、更に平面状態から山折り状態に変わる。第１の綴杆２１２及び第２の綴杆２１４は、開く方向（第１の半割杆２１２ａ及び第３の半割杆２１４ａはＯ₃方向、第２の半割杆２１２ｂ及び第４の半割杆２１４ｂはＯ₄方向）に回転して開く。
開閉部材２４０は、第１の綴杆２１２と第２の綴杆２１４とを開いた状態にしたとき、第１の作動片２３０の突き合わせ縁２３０ａと第２の作動片２３２の突き合わせ縁２３２ａとが山折り状態、すなわち、保持部材２１６の被綴じ物載置部２２２の内側面に近づいた状態に保持するように作用する。 Then, due to the elasticity of the opening / closing member 240, the first operating piece 230 constituting the operating member 218 moves in the direction of closing the binding lock portion 250 (the direction opposite to O ₁ ), and the first The second actuating piece 232 moves in the direction of closing the binding lock 250 (the direction opposite to O ₂ ).
That is, the first working piece 230 and the second working piece 232 gradually change from the valley folded state to the planar state (neutral state), and further change from the planar state to the mountain folded state. The first binding rod 212 and the second binding rod 214 are in the opening direction (the first half-split 212a and the third half-split 214a are in the O ₃ direction, the second half-split 212b and the fourth half-split Wari杆214b is opened by rotating the O ₄ directions).
When the first binding rod 212 and the second binding rod 214 are opened, the opening / closing member 240 has a butt edge 230a of the first working piece 230 and a butt edge 232a of the second working piece 232. It acts to hold in a mountain-folded state, that is, a state approaching the inner surface of the binding object mounting portion 222 of the holding member 216.

保持部材２１６の被綴じ物載置部２２２には、被綴じ物載置部２２２の長手方向に延びる膨出部２２２ａが形成され、膨出部２２２ａは、係合部２３０ｄ及び２３２ｅが上側に向いて回転し且つ係合部２３０ｅ及び２３２ｄが上側に向いて回転するとともに、開閉部材２４０が上側に向いて移動したときに、被綴じ物載置部２２２の内面と当接しないようにするために、被綴じ物載置部２２２の長手方向に延びて形成されている。 A bulging portion 222a extending in the longitudinal direction of the binding object mounting portion 222 is formed in the binding material mounting portion 222 of the holding member 216. In the bulging portion 222a, the engaging portions 230d and 232e face upward. And the engaging portions 230e and 232d rotate upward, and when the opening / closing member 240 moves upward, the engaging portions 230e and 232d do not come into contact with the inner surface of the binding object mounting portion 222. In addition, it is formed to extend in the longitudinal direction of the binding object mounting portion 222.

第１の綴杆２１２は、略円環状の綴杆となるように、半円弧状の第１の半割杆２１２ａと第２の半割杆２１２ｂとから構成され、第２の綴杆２１４は、略円環状の綴杆となるように、半円弧状の第３の半割杆２１４ａと第４の半割杆２１４ｂとから構成されている。そして、用紙Ｐに予め穿設された綴じ孔に挿通して、用紙Ｐを綴じることができるように、第１の半割杆２１２ａおよび第２の半割杆２１２ｂと、第３の半割杆２１４ａと第４の半割杆２１４ｂの先端、すなわち第１の綴杆２１２および第２の綴杆２１４の頂部において、綴杆係止部２５０が形成されている。 The first binding rod 212 includes a semicircular arc-shaped first half split collar 212a and a second half split collar 212b so as to be a substantially annular binding staple. The semicircular arc-shaped third half split bar 214a and the fourth half split bar 214b are formed so as to form a substantially annular binding bar. Then, the first half split 212a and the second half split 212b, and the third half split so that the paper P can be bound by being inserted into a binding hole previously formed in the paper P. A staple binding portion 250 is formed at the tips of 214a and the fourth half-cut collar 214b, that is, at the tops of the first staple 212 and the second staple 214.

前記綴杆を構成する第１の綴杆２１２及び第２の綴杆２１４は、断面円形状金属製線材を、綴杆係止部２５０を外す方向（図３４のＯ₁及びＯ₂の方向）にのばし、且つ中央部分を押さえることによって綴杆を閉じる方向に対してわん曲させて形成されている。そして、第１の綴杆２１２及び第２の綴杆２１４は、中央が綴杆を開く方向（第１の半割杆２１２ａ及び第３の半割杆２１４ａは、図３４のＯ₃方向、第２の半割杆２１２ｂ及び第４の半割杆２１４ｂは、図３４のＯ₄方向）に膨み且つ両端が綴杆を閉じる方向にわん曲した断面略空豆（ビーンズ）型の形状に形成されている。
すなわち、環状の第１の綴杆２１２及び第２の綴杆２１４を開閉方向に見て、第１の綴杆２１２及び第２の綴杆２１４の内側は波状起伏面が形成され、第１の綴杆２１２及び第２の綴杆２１４の外側は半円弧状に形成されている。そして、第１の綴杆２１２及び第２の綴杆２１４は、綴杆を外す方向に見て、両外側が、半円弧状に形成されている。
従来の断面形状丸型の綴杆は、小径だと変形に弱く、大径にすれば断面積が増して材料費がかさみ、従来の断面形状略長方形の綴杆は、用紙にあける綴じ穴には丸穴が多いので、用紙の綴じ穴に対応しにくく、用紙の綴じ穴を傷つけるおそれがある。
ところが、綴杆を構成する第１の綴杆２１２及び第２の綴杆２１４は、細いならば綴杆係止部２５０の嵌合がうまくゆかないときがある。
そのために、第１の綴杆２１２及び第２の綴杆２１４の幅を広げたいが、元の線材として断面積の小さいものを使用しても、元の金属製線材を加工することにより綴杆としては必要な幅が確保されるようにしたい。
そこで、本願発明にかかる綴杆は、それを形成する線材の中央部分を押さえて線材を空豆（ビーンズ）型につぶすことにより全体としての幅を広げ、すなわち、綴杆の全体の幅を綴杆係止部２５０を外す方向に広げて、綴杆係止部２５０の嵌合を完全にできるように形成している。 The first binding rod 212 and the second binding rod 214 constituting the binding rod are directions in which the binding wire locking portion 250 is removed from the circular cross-section metal wire (directions O ₁ and O _{2 in} FIG. 34). It is formed to bend with respect to the direction in which the binding is closed by extending and holding down the central portion. The first binding rod 212 and the second binding rod 214, center opening the binding rod direction (first half rod 212a and the third half rod 214a is O ₃ direction of Figure 34, the 2 of half rod 212b and the fourth half rod 214b is bulging and both ends are formed in the shape of a substantially broad beans (beans) type in which curved in a direction of closing the binding rods in O ₄ direction) in FIG. 34 ing.
That is, when the annular first binding rod 212 and the second binding rod 214 are viewed in the opening and closing direction, a wavy undulating surface is formed inside the first binding rod 212 and the second binding rod 214, and the first The outer sides of the binding rod 212 and the second binding rod 214 are formed in a semicircular arc shape. And the 1st binding rod 212 and the 2nd binding rod 214 are formed in the semicircular arc shape in the both outer sides seeing in the direction which removes a binding staple.
Conventional cross-section round staples are less susceptible to deformation if they have a small diameter, and if the diameter is large, the cross-sectional area increases and material costs increase. Since there are many round holes, it is difficult to correspond to the binding holes of the paper, and there is a risk of damaging the binding holes of the paper.
However, if the first binding pin 212 and the second binding rod 214 constituting the binding rod are thin, the binding of the binding rod locking portion 250 may not be successful.
Therefore, although it is desired to widen the width of the first binding rod 212 and the second binding rod 214, even if the original wire rod having a small cross-sectional area is used, the binding rod is processed by processing the original metal wire rod. I want to ensure the necessary width.
Therefore, the binding rod according to the present invention increases the overall width by pressing the central portion of the wire rod forming the wire rod and crushing the wire rod into a bean shape, that is, the entire width of the binding rod is bound to the binding rod. The locking portion 250 is widened in the direction to be removed, so that the binding of the binding lock portion 250 can be completed completely.

この実施の形態においては、第１の綴杆２１２を構成する第１の半割杆２１２ａ及び第２の半割杆２１２ｂと第２の綴杆２１４を構成する第３の半割杆２１４ａ及び第４の半割杆２１４ｂとは、同じ形状、すなわち曲率（曲率半径）が同じものである。

また、第２の綴杆２１４を構成する第３の半割杆２１４ａと第４の半割杆２１４ｂとは、第３の半割杆２１４ａの自由端の綴杆係止部２５０と、第４の半割杆２１４ｂの自由端の綴杆係止部２５０とを係止することにより、環状に連結される。 In this embodiment, the first half-cotton 212a and the second half-cotton 212b constituting the first binding rod 212 and the third half-cotton 214a and the second half-cotton 214 constituting the second binding rod 214 are used. The 4 half-cut bowl 214b has the same shape, that is, the same curvature (curvature radius).
The first half-split 212a and the second half-split 212b that constitute the first staple 212 are composed of the first half-split 212a and a second half-split. By engaging the binding end locking portion 250 at the free end of the collar 212b, it is connected in an annular shape.

主綴杆たる第１の綴杆２１２を２本の指で挟んで綴杆を閉じ始めるとき、第２の綴杆２１４の第３の半割杆２１４ａの凸部２５６ａと第２の綴杆２１４の第４の半割杆２１４ｂの凹部２５８ｂとが当接する前に（図４６参照）、第１の綴杆２１２の第１の半割杆２１２ａの凸部２５２ａと第１の綴杆２１２の第２の半割杆２１２ｂの凸部２５４ａとが当接し、更に第１の綴杆２１２を閉じるように作動させると、第１の綴杆２１２の第１の半割杆２１２ａの凹部２５２ｂが第２の半割杆２１２ｂの凸部２５４ａ上を摺動するとともに、第１の綴杆２１２の第１の半割杆２１２ａの凸部２５２ａが第２の半割杆２１２ｂの凹部２５４ｂに嵌合される正規の係止位置を通り過ぎて、第１の半割杆２１２ａの凸部２５２ａが第２の半割杆２１２ｂの凹部２５４ｂの傾斜対向面上を摺動してずり上がる（図４７参照）。
このように、第１の綴杆２１２を閉じる方向に作動させると、第２の綴杆２１４の第３の半割杆２１４ａの凸部２５６ａと第２の綴杆２１２の第４の半割杆２１４ｂの凸部２５８ａとが当接し、更に、第１の綴杆２１２を閉じるように作動させると、第２の綴杆２１４の第３の半割杆２１４ａの凸部２５６ａが第４の半割杆２１４ｂの凸部２５８ａの傾斜対向面２５８ｃ上を摺動し（図４６参照）、更に第１の綴杆２１２の第１の半割杆２１２ａの凸部２５２ａが第２の半割杆２１２ｂの凹部２５４ｂの傾斜対向面をずり上がると、第２の綴杆２１４の第３の半割杆２１４ａの凸部２５６ａ（第４の半割杆２１４ｂの凸部２５８ａ）が第４の半割杆２１４ｂの凹部２５８ｂ（第３の半割杆２１４ａの凹部２５６ｂ）に嵌まり込み嵌合する（図４７参照）。
その後、綴杆２１２から指を離し閉じる力を解放すると、開閉部材２４０の作用により第１の綴杆２１２はわずかに開く方向に逆戻りして、第１の綴杆２１２は、第２の綴杆２１４と同様に、第１の半割杆２１２ａの凸部２５２ａ（第２の半割杆２１２ｂの凸部２５４ａ）が第２の半割杆２１２ｂの凹部２５４ｂ（第１の半割杆２１２ａの凹部２５２ｂ）に嵌まり込み嵌合する（図４８参照）。 When the first binding pin 212 that is the main binding rod is sandwiched between two fingers and the binding rod starts to close, the convex portion 256a of the third half-split 214a of the second binding rod 214 and the second binding rod 214 Before the concave part 258b of the fourth half-split bar 214b comes into contact (see FIG. 46), the convex part 252a of the first half-split bar 212a of the first binding bar 212 and the first part of the first binding bar 212 When the convex portion 254a of the second half-cotton 212b is brought into contact with and further operated to close the first binding rod 212, the concave portion 252b of the first half-cotton 212a of the first binding rod 212 becomes the second. And the convex portion 252a of the first half collar 212a of the first binding rod 212 is fitted into the concave portion 254b of the second half collar 212b. After passing through the normal locking position, the convex portion 252a of the first half-cotton 212a becomes the second half-cotton 212b. Ride up the inclined opposing face on parts 254b to slide (see Fig. 47).
In this way, when the first binding rod 212 is operated in the closing direction, the convex portion 256a of the third half-split 214a of the second binding rod 214 and the fourth half-split of the second binding pin 212 are arranged. When the convex portion 258a of 214b is brought into contact with and further operated to close the first binding rod 212, the convex portion 256a of the third half split collar 214a of the second binding rod 214 becomes the fourth half split. It slides on the inclined opposing surface 258c of the convex portion 258a of the collar 214b (see FIG. 46), and the convex portion 252a of the first half collar 212a of the first binding collar 212 further has the second half collar 212b. When the inclined facing surface of the concave portion 254b is lifted, the convex portion 256a of the third half-split 214a of the second binding rod 214 (the convex portion 258a of the fourth half-split 214b) becomes the fourth half-split 214b. Is fitted into the recess 258b (the recess 256b of the third half-cut flange 214a) (see FIG. See 7).
Thereafter, when the finger is released from the binding pin 212 to release the closing force, the opening and closing member 240 causes the first binding pin 212 to reverse slightly in the opening direction, so that the first binding pin 212 is moved to the second binding pin. Similarly to 214, the convex portion 252a (the convex portion 254a of the second half-split plate 212b) of the first half-split plate 212a is the concave portion 254b (the concave portion of the first half-split plate 212a). 252b) (see FIG. 48).

綴杆を閉じるとき、第１の作動片２３０及び第２の作動片２３２は、山折り状態（図４２参照）から徐々に平面状態（中立状態）となり、更に平面状態（中立状態）から谷折り状態（図３７参照）に変わるとともに、同列に並んだ状態から、一旦綴杆係止部２５０の外れる方向（第１の作動片２３０はＯ₁方向、第２の作動片２３２はＯ₂方向）に移動して、たがいちがいに並んだ状態となり（図４７参照）、その後逆戻りして同列に並ぶ。
それによって、移動規制部を構成する第１の作動片２３０の規制凸起２３０ｇが第２の作動片２３２の規制凹部２３２ｆ内を移動して、規制凹部２３２ｆにおける綴杆係止部２５０の外れる方向とは反対側の端縁に当接し、且つ移動規制部を構成する第２の作動片２３２の規制凸起２３２ｇが第１の作動片２３０の規制凹部２３０ｆ内を移動して、規制凹部２３０ｆにおける綴杆係止部２５０の外れる方向とは反対側の端縁に当接する（図４７参照）。そのために、綴杆を閉じるとき、第１の綴杆２１２の第１の半割杆２１２ａの凸部２５２ａが第２の半割杆２１２ｂの凹部２５４ｂに嵌合される正規の停止位置を通り過ぎて、第１の半割杆２１２ａの凸部２５２ａが第２の半割杆２１２ｂの凹部２５４ｂの傾斜対向面上を摺動してずり上がりオーバーランするとき、第１の綴杆２１２の移動距離を規制して適宜な位置でオーバーランが停止され、第１の綴杆２１２の綴杆係止部２５０から指を外せば開閉部材２４０の元の状態に戻ろうとする力が作用して、第１の作動片２３０及び第２の作動片２３２は、一旦綴杆係止部２５０の外れる方向（第１の作動片２３０はＯ₁方向、第２の作動片２３２はＯ₂方向）に移動してたがいちがいに並んだ状態から、逆戻りして同列に並び、綴杆係止部２５０が嵌合する（図３６及び３７参照）。 When closing the binding, the first working piece 230 and the second working piece 232 gradually change from the mountain-folded state (see FIG. 42) to the flat state (neutral state), and further from the flat state (neutral state) to the valley fold. The state is changed to the state (see FIG. 37), and from the state of being aligned in the same row, once the binding lock portion 250 is released (the first operating piece 230 is in the O ₁ direction and the second operating piece 232 is in the O ₂ direction). To the state where they are lined up in a line (see FIG. 47), and then reverse and line up in the same row.
Thereby, the restriction protrusion 230g of the first operating piece 230 constituting the movement restricting portion moves in the restricting recess 232f of the second actuating piece 232, and the binding staple locking portion 250 in the restricting recess 232f is released. The control protrusion 232g of the second working piece 232 that contacts the edge opposite to the side and that constitutes the movement restricting portion moves in the restricting recess 230f of the first actuating piece 230, and in the restricting recess 230f. It abuts on the edge opposite to the direction in which the binding lock portion 250 comes off (see FIG. 47). For this reason, when closing the binding rod, the convex portion 252a of the first half collar 212a of the first binding rod 212 passes through the regular stop position where the convex portion 254b of the second half collar 212b is fitted. When the convex portion 252a of the first half-cut collar 212a slides on the inclined opposing surface of the concave portion 254b of the second half-cut collar 212b and overruns, the movement distance of the first staple 212 is increased. The overrun is stopped at an appropriate position by restricting, and if a finger is removed from the binding hook locking portion 250 of the first binding rod 212, a force to return the opening / closing member 240 to its original state acts, The first operating piece 230 and the second operating piece 232 are moved once in the direction in which the binding latch 250 is disengaged (the first operating piece 230 is in the O ₁ direction and the second operating piece 232 is in the O ₂ direction). From the state in which they are arranged in a row, they are reversed and arranged in the same row, and the binding lock portion 2 50 fits (see FIGS. 36 and 37).

このように、主綴杆たる第１の綴杆２１２を閉じ始めると、直接指で閉じられない副綴杆たる第２の綴杆２１４が閉じる方向に移動を始め、更に第１の綴杆２１２が閉じて正規の係止位置を通り過ぎるまで移動すると、第２の綴杆２１４の係合が進み第１の綴杆２１２より先に第２の綴杆２１４が完全に係止されるので、直接指で閉じられない副綴杆たる第２の綴杆２１４が確実に係止された後、主綴杆たる第１の綴杆２１２が確実に係止される。
したがって、第１の綴杆２１２を指で摘んで先に閉じる方向に移動させたときに、オーバーランするように第１の綴杆２１２を摘まめば、確実に第２の綴杆２１４を正規の位置に係止でき、第１の綴杆２１２の操作のみで、閉じることができる。
このように、第１の綴杆２１２を指で操作することにより第２の綴杆２１４を閉じることができるので、ワンタッチ綴具としての利便性が高い。 In this way, when the first binding 212 as the main binding starts to close, the second binding 214 as the secondary binding that cannot be closed directly with a finger starts to move in the closing direction, and further the first binding 212 Is closed and moved until it passes the normal locking position, the engagement of the second binding rod 214 advances, and the second binding rod 214 is completely locked before the first binding rod 212. After the second binding rod 214, which is a secondary binding rod that cannot be closed by a finger, is securely locked, the first binding rod 212, which is the main binding rod, is securely locked.
Therefore, when the first binding pin 212 is picked with a finger and moved in the first closing direction, if the first binding pin 212 is picked so as to overrun, the second binding pin 214 is surely properly connected. And can be closed only by operating the first binding 212.
Thus, since the 2nd binding pin 214 can be closed by operating the 1st binding pin 212 with a finger | toe, the convenience as a one-touch binding tool is high.

また、第１の綴杆２１２の頂部を指でねじることにより第１の綴杆２１２の綴杆係止部２５０を外したとき、第１の作動片２３０と第２の作動片２３２には、開閉部材２４０が元の状態に戻ろうとする力、すなわち一方の固定先端部２４２ａと他方の固定先端部２４２ｂとが、図３３（Ａ）に示すように、巻線部２４４の円周方向に平行であった元の状態に戻ろうとするように力が働くことにより、第１の綴杆２１２は開く。
そして、第１の綴杆２１２及び第２の綴杆２１４は、その綴杆係止部２５０が外され（図３８参照）、第１の作動片２３０及び第２の作動片２３２は、谷折り状態から徐々に平面状態（中立状態）となり更に平面状態から山折り状態に変わるとともに、綴杆係止部２５０の外れる方向（第１の作動片２３０はＯ₁方向、第２の作動片２３２はＯ₂方向）に移動する。それによって、移動規制部を構成する第１の作動片２３０の規制凸起２３０ｇが第２の作動片２３２の規制凹部２３２ｆ内を移動して、規制凹部２３２ｆにおける綴杆係止部２５０の外れる方向とは反対側の端縁に突き当たり、且つ移動規制部を構成する第２の作動片２３２の規制凸起２３２ｇが第１の作動片２３０の規制凹部２３０ｆ内を移動して、規制凹部２３０ｆにおける綴杆係止部２５０の外れる方向とは反対側の端縁に突き当たる。
第１の綴杆２１２から手を離すと、第１の綴杆２１２及び第２の綴杆２１４は、開閉部材２４０の一方の固定先端部２４２ａと他方の固定先端部２４２ｂとが、図３３（Ａ）に示すように、巻線部２４４の円周方向に平行であった元の状態に戻ろうとするように第１の作動片２３０及び第２の作動片２３２に力を働かせることにより、更に開き（第１の半割杆２１２ａ及び第３の半割杆２１４ａはＯ₃方向、第２の半割杆２１２ｂ及び第４の半割杆２１４ｂはＯ₄方向）、且つ、開閉部材２４０の固定先端部２４２ａと他方の固定先端部２４２ｂとを平面視平行とするように力が働くことにより、第１の作動片２３０と第２の作動片２３２とは、逆方向に移動する（図４１参照）。
すなわち、作動部材２１８及び開閉部材２４０は、第２の綴杆２１４を構成する第３の半割杆２１４ａの凸部２５６ａと第４の半割杆２１４ｂの凸部２５８ａとを開く方向に作用し、そして、第１の綴杆２１２の第１の半割杆２１２ａの凸部２５２ａと第２の半割杆２１２ｂの凸部２５４ａとを引き離す方向に作用するとともに、第２の綴杆２１４を構成する第３の半割杆２１４ａの凸部２５６ａと第４の半割杆２１４ｂの凸部２５８ａとを引き離すように作用する。 In addition, when the binding hook locking portion 250 of the first binding rod 212 is removed by twisting the top of the first binding rod 212 with a finger, the first operating piece 230 and the second operating piece 232 include As shown in FIG. 33 (A), the force at which the opening / closing member 240 returns to the original state, that is, one fixed tip 242a and the other fixed tip 242b are parallel to the circumferential direction of the winding 244. When the force works to return to the original state, the first binding pin 212 is opened.
Then, the first binding pin 212 and the second binding pin 214 are removed from the binding pinching portion 250 (see FIG. 38), and the first working piece 230 and the second working piece 232 are valley-folded.
