背景技術 Background art
複数枚の綴じ用紙を貫通させたコ字状のステープルの脚部を、 綴じ用紙の下面 側で綴じ用紙の裏面に沿わせて折り曲げるようにしたステープラーにおいては、 ステープ の脚部に当接して脚部を折り曲げるためのクリンチヤが上下方向に可 動に支持されており、 ステープルの脚が綴じ用紙を貫通した後でステーブルの脚 をクリンチヤと係合させることにより折り曲げるようにされている。 図 6に示す ように、 クリンチヤ 1は用紙载置部材 2に形成された開口に収容されて用紙載置 部材 2に対して上下方向に移動できるように配置されており、 クリンチヤ 1の下 面とアームカバー 3の底面との間に介装されているパネ 4によって上方に向けて 付勢されている。  In a stapler in which a U-shaped staple leg through which a plurality of sheets of binding paper penetrates is bent along the back surface of the binding paper on the lower surface side of the binding paper, the leg comes in contact with the leg portion of the stapler. A clincher for bending the portion is movably supported in the vertical direction, and is bent by engaging the legs of the staple with the clincher after the legs of the staple have passed through the binding paper. As shown in FIG. 6, the clincher 1 is housed in an opening formed in the paper placing member 2 and is arranged so as to be movable up and down with respect to the paper placing member 2. It is urged upward by a panel 4 interposed between the arm cover 3 and the bottom surface.
用紙載置部材 2は、 クリンチヤアーム 5に沿って前後方向にスライド可能なス ライダ 6がアームカバー 3に形成された支持片 7と用紙載置部材 2の間に介在さ れていることによって、 綴じ操作の開始時にはアームカバー 3に対して上方位置 に保持されており、 クリンチヤ 1の上端面のステーブル誘導溝 8が用紙載置部材 2に形成された開口 9の上端縁に望んだ位置に配置されている。  The paper placing member 2 is formed by a slider 6 slidable in the front-rear direction along the clincher arm 5 between the support piece 7 formed on the arm cover 3 and the paper placing member 2. At the start of the binding operation, it is held at an upper position with respect to the arm cover 3, and the stable guide groove 8 on the upper end surface of the clincher 1 is located at a desired position on the upper edge of the opening 9 formed in the paper placing member 2. Are located in
用紙載置部材 2の上面に配置された綴じ用紙に対してステーブルが打ち込まれ て、 ステーブルの脚先端が綴じ用紙を貫通して綴じ用紙の裏面側に貫通すると、 ステーブルの先端がクリンチヤ 1の上端面と当接してクリンチヤ 1を用紙載置部 材 2に対して下方へ移動させる。 用紙載置部材 2上に支持されている綴じ用紙を ステーブルが貫通した後、 スライダ 6が後方側に作動されて用紙载置部材 2が下 側へ揺動自由となり、 ステープルが更に下方へ移動されて、 ステープルの脚部が クリンチヤ 1によって一気に折り曲げられるようにされている。 When the stable is driven into the binding paper arranged on the upper surface of the paper placing member 2, and the leading end of the stable penetrates the binding paper and penetrates to the back side of the binding paper, the leading end of the stable is clinched. The clincher 1 is moved downward with respect to the paper placing member 2 in contact with the upper end surface of the first. The binding paper supported on the paper After the staple has penetrated, the slider 6 is actuated to the rear side, and the paper placing member 2 is free to swing downward, the staple is further moved downward, and the staple leg is bent at once by the clincher 1. It has been like that.
図 7 ( a ) に示すように、 従来のクリンチヤ 1はアームカバー 3の側壁の内側 に配置されて上下方向に揺動可能な用紙載置部材 2に形成されている開口 9内に 収容されており、 クリンチヤ 1の下端部の幅方向の寸法を大きくすることができ ない。 このため、 クリンチヤがアームカバーの底面に着いたときにステ^"プルに よる偏荷重でクリンチヤにモーメントが発生して図7 ( b ) のように、 クリンチ ャが傾いたままになってしまい、 従ってクリンチヤのステープル誘導溝が傾いた 状態となって、 この結果、 スライダが後方へ移動して用紙载置部材とともにステ 一プルが下方向に下降した際にステープルの脚部を座屈させてしまうことがあつ た。 発明の開示 As shown in FIG. 7 (a), the conventional clincher 1 is disposed inside the side wall of the arm cover 3 and is housed in an opening 9 formed in the paper placing member 2 which can swing vertically. As a result, the width dimension of the lower end of the clincher 1 cannot be increased. As a result, when the clincher reaches the bottom of the arm cover, a moment is generated in the clincher due to the eccentric load due to the step pull, and the clincher remains inclined as shown in FIG. 7 (b). Accordingly, the staple guide groove of the clincher is inclined, and as a result, when the slider moves rearward and the staple descends together with the paper placing member, the leg of the staple buckles.

図 2に示すように、 タリンチヤ 2 2の下部は前記用紙载置部材 2 4の両側へ突 出されるように両側面方向に張り出されて幅広く形成されており、 この両側の張 り出し部 2 2 aがアームカバー 2 1の両側壁 3 1の内壁面に形成されているガイ ド溝 3 2 (案内部） に収容されて、 このガイド溝 3 2によってクリンチヤ 2 2が 上下方向への移動の案内が行われるようにされている。 なお、 クリンチヤ 2 2の 上部を用紙載置部材 2 4の開口 2 5によって案内させてもよい。  As shown in FIG. 2, the lower portion of the tarincher 22 is formed so as to protrude toward both sides so as to protrude to both sides of the paper placing member 24 and is formed widely. 2a is housed in guide grooves 32 (guide portions) formed on the inner walls of both side walls 31 of the arm cover 21. The guide grooves 32 allow the clincher 22 to move in the vertical direction. Guidance is provided. The upper portion of the clincher 22 may be guided by the opening 25 of the paper placing member 24.
図 4及び図 5により、 クリンチヤ 2 2の下部の張り出し部 2 2 aの寸法設定に ついて説明する。 傾いたクリンチヤ 2 2がアームカバー 2 1の底面に着座してス テープノレ Sの傾きを矯正させる作用は、 クリンチヤ 2 2の上面に形成されている クリンチヤ溝 2 3の高さ hと、 前記クリンチヤ溝 2 3に傾いたステーブル Sの脚 が接地 （着地） する位置から下部の張り出し部 2 2 aの側端 （すなわち、 クリン チヤ 2 2の側縁部） までの寸法 dとの寸法比に関係する。 実験で求めた結果によ れば、 図 5のグラフ図に示すように、 張り出し部の寸法 d = 0 . 3 2 'クリンチ ャの高さ hの関係を境にして、 張り出し部 2 2 aの張り出し寸法 dがこれより小 さいと座屈の発生頻度が多くなることが判明した。 従って張り出し部 2 2 aの張 り出し寸法 dをクリンチヤの高さ hの 0 . 3 2倍以上に設定することにより座屈 の発生を防止することができる。 なお、 張り出し寸法 dの上限値は特に限定され ないが、 ステープラーのアームカバー 2 1を取り扱う上で支障がない大きさとす ればよい。 With reference to FIG. 4 and FIG. 5, the dimension setting of the projecting portion 22a at the lower portion of the clincher 22 will be described. The function of the inclined clincher 22 to be seated on the bottom surface of the arm cover 21 to correct the inclination of the stapler S is based on the height h of the clincher groove 23 formed on the upper surface of the clincher 22 and the clincher groove. It is related to the dimension ratio to the dimension d from the position where the leg of the stable S inclined at 23 to the ground (landing) to the side edge of the lower overhang 22 a (that is, the side edge of the clincher 22). I do. According to the results obtained in the experiment, as shown in the graph of FIG. 5, the dimension of the overhang portion d = 0.32 'clinch It has been found that the frequency of buckling increases when the overhang dimension d of the overhang portion 22a is smaller than this, based on the relationship of the height h of the shaft. Therefore, buckling can be prevented by setting the overhang dimension d of the overhang portion 22a to be at least 0.32 times the height h of the clincher. The upper limit of the overhang dimension d is not particularly limited, but may be a size that does not hinder the handling of the stapler arm cover 21.
以下、 図 3 ( a ) から 3 ( d ) に基づいて上記実施例の作動状態を説明する。 図 3 ( a ) に示すように用紙載置部材 2 4の上面に配置された綴じ用紙 Pにステ 一プル Sが打ち込まれると、 綴じ用紙 Pを貫通したステープル Sの脚がクリンチ ャ 2 2の上面と当接して、 クリンチヤ 2 2をバネ 2 6の付勢力に抗して下方向に 移動させる。 なお、 上記綴じ操作の初期においては、 用紙載置部材 2 4とタリン チヤアーム 1 4の間にスライダ 2 8が配置されており、 用紙載置部材 2 4は上方 位置に支持されている。  The operation of the above embodiment will be described below with reference to FIGS. 3 (a) to 3 (d). As shown in FIG. 3 (a), when the staple S is driven into the binding paper P arranged on the upper surface of the paper placing member 24, the legs of the staple S penetrating the binding paper P are attached to the clincher 22. The clincher 22 is moved downward against the urging force of the spring 26 by contacting the upper surface. In the initial stage of the binding operation, the slider 28 is disposed between the paper placing member 24 and the talincher arm 14, and the paper placing member 24 is supported at an upper position.
図 3 ( b ) に示すように、 ステープノレ Sの脚が綴じ用紙 Pを貫通する際にステ 一プル Sに傾きが発生した場合には、 ステープル Sの一方の脚がクリンチヤ 2 2 と係合してクリンチヤ 2 2の片側を下側へ押圧して傾かせるようにして下方向に 作動させるが、 クリンチヤ 2 2の下部はアームカバー 2 1の両側壁 3 1に形成さ れたガイド溝 3 2内で案内されているため、 クリンチヤ 2 2の傾きが大きくなる ことなく下方向に移動される。 クリンチヤ 2 2がステープル Sの偏荷重による回 転モーメントにより回転しないように張り出し部 2 2 aが幅広く形成されている ため、 クリンチヤ 2 2は傾かずにアームカバー 2 1の底面と水平になろうとする 図 3 ( c ) に示すように、 ステーブル Sの脚部が綴じ用紙 Pを貫通した後、 ス ライダ 2 8が後方側へ作動されて用紙載置部材 2 4とタリンチヤアーム 1 4の間 力 ら退避し、 これによつて用紙載置部材 2 4が下方向へ揺動可能となる。  As shown in FIG. 3 (b), if the staple S is inclined when the legs of the staple S pass through the binding paper P, one leg of the staple S engages the clincher 22. Pressing one side of the clincher 22 downward and tilting it to operate downward, the lower part of the clincher 22 is in the guide groove 3 2 formed in both side walls 3 1 of the arm cover 21. The clincher 22 is moved downward without increasing the inclination. The overhanging portion 22a is formed wide so that the clincher 22 does not rotate due to the rotational moment due to the eccentric load of the staple S. As shown in FIG. 3 (c), after the legs of the stable S have penetrated the binding paper P, the slider 28 is actuated to the rear side so that the space between the paper placing member 24 and the tarinchi arm 14 is formed. The sheet placement member 24 is allowed to swing downward by retracting from the force.
図 3 ( d ) に示すように、 図 3 ( c ) の偏荷重を受けた状態で更にステープノレ Sと綴じ用紙 Pが下方向へ押圧された場合であっても、 クリンチヤ 2 2は傾くこ となく綴じ用紙 Pの下面に貫通したステーブル sの脚が座屈せず、 クリンチヤ溝 2 3によって互いに内側に向けて誘導されて綴じ用紙 Pの下面に沿って折り曲げ られて綴じ用紙 Pが綴じられる。 As shown in Fig. 3 (d), even when the stapler S and the binding paper P are further pressed downward under the biased load shown in Fig. 3 (c), the clincher 22 is inclined. The legs of Stable s penetrating the lower surface of binding paper P do not buckle and clinch grooves The binding paper P is guided inward by 23 and is bent along the lower surface of the binding paper P to bind the binding paper P.
