Description

【０００１】
【発明の属する技術分野】
本発明は、綴じ具及びこれを用いたファイルに係り、更に詳しくは、表紙体に対して容易に着脱することのできる綴じ具と、この綴じ具を用いたファイルに関する。
【０００２】
【従来の技術】
従来より、表紙体の内面側に綴じ具を備えてなるファイルが広く利用されている。このファイルに用いられる綴じ具は、表紙体の内面側に配置されるベースと、このベースに設けられた綴じ部材とを備えて構成されている。この綴じ具を表紙体に取り付ける場合には、表紙体とベースに穴をそれぞれ設けておき、この穴を利用してリベット等を打ち込んで固定する構成が一般的に採用されている。
【０００３】
しかしながら、このような構成では、綴じ具がリベットによって表紙体に固定されているため、表紙体と綴じ具とを分離することが非常に困難となる。
【０００４】
そこで、最近では、表紙体と綴じ具との分離を容易に行うことのできるタイプのファイルが出現するに至っている。このファイルにおける綴じ具は、表紙体の外面側に配置される外側部材と、前記ベース上に配置される抜け止め部材とを用いて固定される構成が採用されている。すなわち、外側部材は、表紙体と綴じ具のベースを部分的に貫通する爪部材を備えている一方、抜け止め部材は、爪部材に引っ掛けられて当該爪部材の脱落を防止する構成となっている。従って、抜け止め部材を取り外すことによって、外側部材がベースと表紙体の穴から抜け出ることができ、これによって表紙体と綴じ具との分離が可能となる。
【０００５】
【発明が解決しようとする課題】
しかしながら、表紙体と綴じ具との分離を可能とするファイルにあっては、綴じ具自体が完成品であり、これとは別個の部品、すなわち、前述した外側部材や、抜け止め部材等を用いなければ綴じ具を表紙体に固定することはできない。そのため、綴じ具自体を完成させる組み立て工程と、綴じ具を表紙体に装着するファイル組み立て工程とがそれぞれ独立したものとなり、また、全体として、部品点数も多くなるという不都合を招来する。
【０００６】
【発明の目的】
本発明は、このような不都合に着目して案出されたものであり、その目的は、綴じ具を構成する部品を用いて表紙体を挟み込むことができ、この挟み込みによって綴じ具とファイルとを同時に完成させることのできる綴じ具及びこれを用いたファイルを提供することにある。
【０００７】
【課題を解決するための手段】
前記目的を達成するため、本発明は、所定の表紙体の外面側に位置する外側綴じ具形成部材と、前記表紙体の内面側に位置して前記外側綴じ具形成部材との間に表紙体を挟み込む内側綴じ具形成部材とを備え、
前記外側綴じ具形成部材は、前記表紙体を貫通して当該表紙体の内面側に位置する第１の綴じ部材を備える一方、
前記内側綴じ具形成部材は、前記第１の綴じ部材と相互に作用して閉ループを形成可能な第２の綴じ部材を備える、という構成を採っている。このような構成によれば、各綴じ具形成部材で表紙体をサンドイッチするように組み合わせることで綴じ具が形成されることとなり、この綴じ具の形成と同時にファイルも形成されることとなる。従って、従来のような綴じ具固定用の部品を一切必要とすることなく綴じ具が形成でき、コスト的にも大幅な低減を図ることが可能となる。
【０００８】
【発明の実施の形態】
本発明において、前記外側綴じ具形成部材は、前記表紙体と係り合う脱落防止部を備えた構成とすることが好ましい。このような脱落防止部を設ければ、表紙体と外側綴じ具形成部材との相対的な固定位置が安定した状態に保たれ、外側綴じ具形成部材がぐらついたりする虞を効果的に防止することができる。この際、外側綴じ具形成部材の端部は前記表紙体の内面側に位置する連結部を備え、この連結部に前記内側綴じ具形成部材の端部が回転可能に連結されて前記閉ループの形成及び解除が可能に設けられる、という構成を採用するとよい。これによれば、外側綴じ具形成部材が表紙体から抜け落ちることなく当該外側綴じ具形成部材に対して内側綴じ具形成部材を回転させることができる。
【０００９】
更に、前記内側綴じ具形成部材と表紙体との間には中間部材が設けられ、この中間部材と前記外側綴じ具形成部材とが相互に連結される、という構成も採用することができる。このような構成を採れば、外側綴じ具形成部材が表紙体に対して更に強固に固定されることとなる。しかも、前記中間部材を平坦に形成すれば、前記閉ループを解除した際に、表紙体の内面側に凹凸面が表れることもなくなって外観上の体裁を良好に保つことができ、且つ、書類の端部が引っ掛かるような虞も防止することができる。
【００１０】
また、本発明に係るファイルは、表紙体と、当該表紙体に着脱自在に装着される綴じ具とからなり、
前記綴じ具は、前記表紙体の外面側に位置するとともに一部が表紙体を貫通して当該表紙体の内面側に位置する第１の綴じ部材を備えた外側綴じ具形成部材と、前記表紙体の内面側に位置して前記外側綴じ具形成部材との間に表紙体を挟み込むとともに、前記第１の綴じ部材と相互に作用して閉ループを形成可能な第２の綴じ部材とを備えた内側綴じ具形成部材とにより構成される、という構成を採っている。これにより、前述したように、綴じ具とファイルとを同時に完成できる他、表紙体と綴じ具とを難なく分離することができるため、表紙体が老朽化しても、当該表紙体のみを新たなものに交換することができ、綴じ具が使用可能な状態である限り、当該綴じ具の永続的な利用が可能となる。しかも、表紙体と綴じ具とが異種材料からなる場合の分別廃棄も難なく行うことができる。
【００１１】
前記ファイルにおいて、表紙体には、前記外側綴じ具形成部材の一部を受容する開放部が形成されている一方、前記外側綴じ具形成部材には、前記開放部内に位置して当該開放部の形成縁と係り合う脱落防止部が設けられる、という構成を採ることが好ましい。このようなファイルによれば、開放部に脱落防止部を引っ掛けることにより、外側綴じ具形成部材を表紙体に容易に保持させることができ、外側綴じ具形成部材の固定位置を安定化させることが可能となる。特に、表紙体と外側綴じ具形成部材とを相互に組み合わせた後工程で、内側綴じ具形成部材を表紙体の内面側に装着するという生産ラインを構築することが可能となり、生産効率も飛躍的に向上させることができる。
【００１２】
更に、前記表紙体は、外側綴じ具形成部材と内側綴じ具形成部材との間で相互に突き合う二分割構造とすることができる。このような構成では、表表紙と裏表紙とを色違いとした斬新な表紙構造を種々採用することが容易となり、従って、利用者のニーズに応じたファイルの提供が可能となる。しかも、表紙体の上下幅と綴じ具の上下幅を同程度にすることで、前記突き合わせ領域を完全に隠すことができ、外観上は、一枚の表紙体によって形成されているように表すことが可能となる。
【００１３】
また、前記内側綴じ具形成部材と表紙体との間には中間部材が設けられ、この中間部材と前記外側綴じ具形成部材とが相互に連結される、という構成を採るとよい。
【００１４】
なお、本明細書において、位置若しくは方向を示す用語は、特に明示しない限り、図３を基準として用いるものとする。
【００１５】
【実施例】
以下、本発明の実施例を図面を参照しながら説明する。
【００１６】
［第１実施例］
図１には、第１の実施例に係るファイルの概略斜視図が示され、図２には、図１の分解斜視図が示されている。また、図３には、ファイルの要部平面図が示されている。これらの図において、ファイル１０は、中間に背表紙１１を介して左右両側に連なる表表紙１２及び裏表紙１３を有する表紙体１５と、前記背表紙１１の領域内において当該背表紙１１の上下方向に沿って装着されるとともに、背表紙１１の上下幅と略同程度の上下幅を有する綴じ具１６とを備えて構成されている。
【００１７】
前記背表紙１１は、図２に示されるように、当該背表紙１１の上下方向、すなわち長手方向に沿って所定間隔を隔てて三箇所に形成された開放部としての撥形穴部１９と、背表紙１１の一端部近傍に形成された台形穴部２０と、背表紙１１の他端部に形成された開放部としての凹状切欠部２１とを備えた形状に設けられている。
【００１８】
前記綴じ具１６は、背表紙１１の外面側に位置する外側綴じ具形成部材２４と、背表紙１１の内面側に位置する内側綴じ具形成部材２５との組み合わせによって構成されている。外側綴じ具形成部材２４は、略長方形状をなして背表紙１１の外面側に位置するとともに、外面に見出し表示用の凹部２７Ａ（図４参照）が形成された外側平面部２７と、この外側平面部２７の内面側に設けられるとともに、前記撥形穴部１９内にそれぞれ受容される台状部２８と、前記台形穴部２０内に受容されるとともに、前記内側綴じ具形成部材２５の自由端側と係り合い可能な略Ｌ字状の爪部２９と、前記凹状切欠部２１内に受容される連結部３０とを備えて構成されている。
【００１９】
前記台状部２８は、前記撥形穴部１９の開口形状に対応した基部２８Ａと、この基部２８Ａの一端側に位置して当該基部２８Ａとの間に隙間を形成する屈曲爪状部２８Ｂとからなる。これら台状部２８のうち、中央の台状部２８を除く両側の台状部２８には、第１の綴じ部材を構成する略半円弧状の綴じ足３１が一体的に設けられている。また、台状部２８において、前記外側平面部２７の短寸幅方向に沿う両端部には、図４に示されるように、撥形穴部１９の形成縁に係り合う脱落防止部としての溝部２８Ｃ,２８Ｃがそれぞれ形成されている。
【００２０】
前記連結部３０は、図５にも示されるように、平面状をなす基面部３４と、この基面部３４の一端に連なって当該基面部３４との間に隙間を形成する内面部３５とにより構成されている。ここで、基面部３４には、前記台状部２８に形成されたのと同様に、凹状切欠部２１の左右形成縁に係り合う脱落防止部としての溝部３４Ａが形成されている。また、内面部３５には、内側綴じ具形成部材１６の回転中心を形成する軸受穴３５Ａが形成されている。
【００２１】
前記内側綴じ具形成部材１６は、前記背表紙１１の内面側に位置する内側平面部３６と、この内側平面部３６の短寸幅方向一端側に沿って二箇所に設けられた第２の綴じ部材としての綴じ足３７を備えて構成されている。これら綴じ足３７は略半円弧状をなし、前記第１の綴じ部材を構成する綴じ足３１と相互に作用して閉ループを形成可能となっている。
【００２２】
前記内側平面部３６において、綴じ足３７の基部位置とは反対側には前記台状部２８の屈曲爪状部２８Ｂを受容する凹状の切欠部３８と、前記爪部２９を受容して当該爪部２９に係脱する面形状を備えたストッパ片部３９が形成されている。内側平面部３６の長手方向一端部には、当該内側平面部３６の面よりも若干面位置が低い陥没面部４１が形成され、この陥没面部４１の領域内に前記軸受穴３５Ａに挿入される軸４２が形成されている。また、内側平面部３６の他端側、すなわち、前記ストッパ片部３９に隣接する端部側には、滑り止め用のリブが複数設けられた操作部４４が形成されている。
【００２３】
以上の構成において、ファイル１０を完成させるには、先ず、背表紙１１の外面側に外側綴じ具形成部材２４を位置させ、前記綴じ足３１,３１を撥形穴部１９内に挿入して貫通させる。この際、台状部２８を撥形穴部１９内に収まるように完全に押し込むことで、各台状部２８に形成された溝部２８Ｃが撥形穴部１９の形成縁に係り合うこととなり、また、連結部３０の溝部３４Ａも凹状切欠部２１の左右形成縁に係り合い、これによって、外側綴じ具形成部材２４の安定した位置を維持して当該外側綴じ具形成部材２４を背表紙１１に保持させることができる。
【００２４】
次いで、前記内側綴じ具形成部材２５を背表紙１１の内面側に装着すればよい。この装着は、前記陥没面部４１を、連結部３０の基面部３４及び内面部３５間の隙間内に差し込んで軸４２を内面部３５の軸受穴３５Ａに強制的に嵌め込むことによって行うことができる。これにより、内側綴じ具形成部材２５は、その内側平面部３６が、図７中矢印で示されるように、背表紙１１と略平行な面内で回転可能となり、綴じ足３７,３７の各先端を対応する綴じ足３１,３１の各先端に突き当てることで閉ループが形成でき、同時に、内側平面部３６の自由端側に位置するストッパ片部３９が爪部２９に係り合って前記閉ループを維持するようになっている。この閉ループを解除する場合には、前記操作部４４を押圧して爪部２９とストッパ片部３９との係り合いを解除し、この状態で、内側綴じ具形成部材２５を回転させればよい。
【００２５】
従って、このような実施例によれば、綴じ具１６を構成する外側綴じ具形成部材２４と内側綴じ具形成部材２５とによって背表紙１１を挟み込むように組み合わせるだけで綴じ具１６が完成し、且つ、ファイル１０も同時に完成することが可能となる。
【００２６】
次に、本発明の前記以外の実施例について説明する。なお、以下の説明において、前記第１の実施例と同一若しくは同等の構成部分については必要に応じて同一符号を用いるものとし、説明を省略若しくは簡略にする。
【００２７】
[第２実施例]
図８ないし図１３には、第２の実施例が示されている。この第２の実施例は、内側綴じ具形成部材２５と背表紙１１との間に中間部材５０を設け、この中間部材５０と外側綴じ具形成部材２４とによって背表紙１１を挟み込むようにした点に主な特徴を有する。
【００２８】
すなわち、外側綴じ具形成部材２４の長手方向一端縁には、短寸幅方向に沿って延びる突条部５１が設けられ、この突条部５１の内縁側にガイド溝５２が形成されている。この一方、前記長手方向他端側に設けられた連結部３０の内縁にガイド溝５３が設けられるとともに、綴じ足３１,３１をそれぞれ支持する各台状部２８の基部２８Ａにも、ガイド溝５４がそれぞれ形成されている。ここで、外側綴じ具形成部材２４には、第１の実施例で示した爪部２９が一方の台状部２８と一体型に設けられ、背表紙１１に形成された穴部１９の開放形状もこれに対応した形状に設けられている。また、外側綴じ具形成部材２４の中央部には背表紙１１の中央に形成された角穴６３に受容される突起５５が形成されている。
【００２９】
前記中間部材５０は、全体的に平坦な板状部材からなり、その長手方向両端側における背表紙１１側の面には、前記外側綴じ具形成部材２４の長手方向両側に位置するガイド溝５２,５３にスライド操作で嵌り込むレール片５８,５９が形成され、また、中間領域には、前記台状部２８の各ガイド溝５４に嵌り込むレール片６１が形成されている。
【００３０】
前記中間部材５０は、外側綴じ具形成部材２４を背表紙１１の外側から装着した状態で、前記各レール片５８,５９,６１を対応するガイド溝５２,５３,５８にスライド操作で嵌め込むことで、外側綴じ具形成部材２４が背表紙１１に強固に固定されることとなる。
【００３１】
なお、前記第１の実施例では、内側綴じ具形成部材２５の回転中心となる軸４２が内側綴じ具形成部材２５側に設けられているが、この第２の実施例では、内側綴じ具形成部材２５の端部に穴６５を形成する一方、前記外側綴じ具形成部材２４の連結部３０に割り軸６６を形成し、この割り軸６６を穴６５内に強制的に嵌め込むことによって内側綴じ具形成部材２５が回転可能に連結されている。また、内側綴じ具形成部材２５は、その操作部４４の内方にストッパ穴６９が形成され、このストッパ穴６９に外側綴じ具形成部材２４の爪部２９が係脱可能とされている。その他の構成は、実質的に前記第１の実施例と略同様となっている。
【００３２】
従って、このような第２の実施例によれば、外側綴じ具形成部材２４を背表紙１１に対して一層強固に固定することができる一方、中間部材５０を取り外すだけで表紙体１５と綴じ具１６とを相互に分離することができる。しかも、中間部材５０が平坦な面に設けられているため、内側綴じ具形成部材２５を開放位置に回転させた場合でも凹凸が表出することは殆どない。
【００３３】
[第３実施例]
図１４ないし図１６には、本発明の第３の実施例が示されている。この第３の実施例は、表紙体１５を二分割構造とした点に特徴を有する。
【００３４】
すなわち、表紙体１５は、１／２幅背表紙片１１Ａを一端に備えた表表紙１２と、１／２幅背表紙片１１Ｂを一端に備えた裏表紙１３とにより構成され、前記背表紙片１１Ａ,１１Ｂにより背表紙１１が形成されている。各背表紙片１１Ａ,１１Ｂの略中央部には、丸穴７０が形成されており、これらの丸穴７０に挿入される凸部７１が外側綴じ具形成部材２４の内面側に形成されている。なお、背表紙片１１Ａ,１１Ｂには、図１５に示されるように、外側綴じ具形成部材２４の台状部２８、連結部３０及び後述するフック部を受容する開放部としての切欠部７５が複数箇所に形成されている。
【００３５】
外側綴じ具形成部材２４の端部には、内側綴じ具形成部材２５の自由端の裏面側を受け入れてこれに係脱可能となるフック部７２が設けられており、このフック部７２と前記自由端とが係り合ったときに、綴じ足３１,３７が閉ループを形成するようになっている。なお、外側綴じ具形成部材２４の略中央部には、図１５及び図１６に示されるように、面位置を陥没させた凹部７５が形成されている。
【００３６】
この第３の実施例では、図１６（Ｂ）に示されるように、外側綴じ具形成部材２４の短寸幅方向（左右方向）両側から表表紙１２及び裏表紙１３を突き合わせるように矢印方向に差し込むことで背表紙片１１Ａ,１１Ｂの各丸穴７０に凸部７１を嵌め込むことができ、この嵌め込みにより、表紙体１５は上下及び左右に移動不能に保たれる。従って、綴じ具１６が完成された状態であっても、当該綴じ具１６に表表紙１２及び裏表紙１３を組み込むことが可能となる。
【００３７】
なお、表紙体１５と綴じ具１６とを分離するときは、図１６（Ｃ）に示されるように、スクリュードライバ等の先端を背表紙片１１Ａ,１１Ｂの突合せ端部間から前述した凹部７５まで差し込み、梃子の原理を利用してドライバの先端を回転させることで丸穴７０と凸部７１との嵌め合わせを強制的に解除すればよい。その他の構成は、実質的に、前記第１及び第２の実施例と部分的に略共通した構造となっており、同一符号のみを示して説明を省略する。
【００３８】
従って、このような第３の実施例によれば、表表紙１２と裏表紙１３とを種々選択して色、質等が異なる各種外観形態を表出する表紙構造となるファイルを提供することができる。また、このように表表紙１２と裏表紙１３とを突き合わせる構造であっても、当該突き合わせ領域が綴じ具１６によって覆われるため、外観上は恰も一枚の表紙によって構成されているように表出させることができ、色違い、或いは質感を異ならせる種々の組み合わせによって、斬新性に富んだファイルを提供することができる。
【００３９】
なお、前記各実施例では、綴じ具１６の装着部位が背表紙１１の内面である場合を図示、説明したが、本発明はこれに限定されるものではなく、裏表紙１３の内面側を装着部位としてもよい。また、綴じ足の数も限定されるものではなく、必要に応じて増加させることもできる。要するに、本発明は、外側綴じ具形成部材２４と内側綴じ具形成部材２５によって表紙体１５を挟み込みでき、且つ、綴じ具１６が表紙体１５と分離可能となる構造を採用する限りにおいて、種々の設計変更をすることができる。
【００４０】
【発明の効果】
以上説明したように、本発明に係る綴じ具は、第１の綴じ部材を備えた外側綴じ具形成部材と、当該外側綴じ具形成部材と相互に作用して表紙体を挟み込むとともに第１の綴じ部材と相互に作用して閉ループを形成可能な第２の綴じ部材を備えた内側綴じ具形成部材とによって形成されているから、各綴じ具形成部材で表紙体を挟み込むように組み合わせるだけで綴じ具が完成され、且つ、これと同時にファイルも完成されるという効果を得る。
【００４１】
また、外側綴じ具形成部材は、前記表紙体と係り合う脱落防止部を備えているため、表紙体と外側綴じ具形成部材との固定位置が安定することとなり、外側綴じ具形成部材がぐらついたりする虞も防止することができる。また、外側綴じ具形成部材の端部に内側綴じ具形成部材の端部が回転可能に連結された構成では、表紙体を挟み込んだ状態を維持しながら各綴じ具形成部材の端部側において綴じ部材の開閉を行うことができる。
【００４２】
更に、前記内側綴じ具形成部材と表紙体との間に中間部材を設けて当該中間部材と外側綴じ具形成部材とが相互に連結される構成とした場合には、第１及び第２の綴じ部材を開放したときに、前記中間部材が表出する状態となって凹凸面が表れることのない設計が可能となり、書類の端部が引っ掛かるような虞も防止することができる。
【００４３】
また、本発明に係るファイルは、綴じ具を構成する外側綴じ具形成部材と内側綴じ具形成部材とを分離可能な状態で相互に組み合わせるだけで構成されるため、表紙体のみを新たなものに交換することができ、綴じ具が使用可能な状態である限り、当該綴じ具の永続的な利用が可能となる。しかも、表紙体と綴じ具とが異種材料からなる場合の分別廃棄も難なく行うことができる。
【００４４】
更に、前記ファイルにおける表紙体は、外側綴じ具形成部材の一部を受容する開放部が形成されている一方、前記外側綴じ具形成部材には、前記開放部内に位置して当該開放部の形成縁と係り合う脱落防止部が設けられる構成としたから、開放部に脱落防止部を引っ掛けることにより、外側綴じ具形成部材を表紙体に容易に保持させることができ、外側綴じ具形成部材の固定位置を安定化させることが可能となる。特に、表紙体と外側綴じ具形成部材とを相互に組み立てた後工程で、内側綴じ具形成部材を表紙体の内面側に装着するという生産ラインを構築することが可能となり、生産効率も飛躍的に向上させることができる。
【００４５】
また、前記表紙体を二分割構造とした構成では、表表紙と裏表紙とを色違いとした斬新な表紙構造を種々採用することが容易となり、従って、利用者のニーズに応じたファイルの提供が可能となる。

BACKGROUND OF THE INVENTION
The present invention relates to a binding tool and a file using the binding tool, and more particularly to a binding tool that can be easily attached to and detached from a cover body and a file using the binding tool.
[0002]
[Prior art]
Conventionally, a file having a binding tool on the inner surface side of a cover body has been widely used. The binding tool used in this file includes a base disposed on the inner surface side of the cover body and a binding member provided on the base. When attaching the binding tool to the cover body, a structure is generally employed in which holes are provided in the cover body and the base, and rivets or the like are driven and fixed using the holes.
[0003]
However, in such a configuration, since the binding tool is fixed to the cover body by rivets, it is very difficult to separate the cover body and the binding tool.
[0004]
Therefore, recently, a file of a type that can easily separate the cover body and the binding tool has appeared. The binding tool in this file employs a structure that is fixed using an outer member disposed on the outer surface side of the cover body and a retaining member disposed on the base. In other words, the outer member includes a claw member that partially penetrates the cover body and the base of the binding tool, while the retaining member is configured to be hooked on the claw member to prevent the claw member from falling off. Yes. Therefore, by removing the retaining member, the outer member can come out of the hole of the base and the cover body, and thus the cover body and the binding tool can be separated.
[0005]
[Problems to be solved by the invention]
However, in a file that allows separation of the cover body and the binding tool, the binding tool itself is a finished product, and separate parts, that is, the above-described outer member, retaining member, etc. are used. Without this, the binding tool cannot be fixed to the cover. For this reason, the assembly process for completing the binding tool itself and the file assembly process for mounting the binding tool on the cover body are independent of each other, and the number of parts is increased as a whole.
[0006]
OBJECT OF THE INVENTION
The present invention has been devised by paying attention to such inconveniences, and the object of the present invention is to be able to sandwich the cover body using the components constituting the binding tool, and the binding tool and the file can be sandwiched by this sandwiching. It is to provide a binding tool that can be completed simultaneously and a file using the binding tool.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a cover body between an outer binding tool forming member positioned on the outer surface side of a predetermined cover body and an outer binding tool forming member positioned on the inner surface side of the cover body. An inner binding tool forming member sandwiching
While the outer binding tool forming member includes a first binding member that penetrates the cover body and is located on the inner surface side of the cover body,
The inner binding tool forming member includes a second binding member that can interact with the first binding member to form a closed loop. According to such a configuration, the binding tool is formed by combining the binding members so that the cover body is sandwiched between the binding tool forming members, and the file is formed simultaneously with the formation of the binding tool. Therefore, the binding tool can be formed without requiring any conventional parts for fixing the binding tool, and the cost can be greatly reduced.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
In the present invention, it is preferable that the outer binding tool forming member includes a drop-off preventing portion that engages with the cover body.
