Description

【0001】
【発明の属する技術分野】
本発明は、盤状をなす綴じ具に紙葉類を綴じるようにしたファイルに関するものである。
【0002】
【従来の技術】
従来より、紙葉類を綴じるためのファイルの一種として、表表紙部、裏表紙部、及び背表紙部を備えた表紙本体と、背表紙部に形成したスリットに例えば円盤状等の盤状をなす一又は複数の綴じ具たるリングとを備え、このリングの盤面に、紙葉類の綴じ側の縁部に形成した切り込みを差し込んで係合させるようにしたものが考えられている。
【0003】
このようなファイルでは、リングの周縁部の肉厚をそれよりも内側の盤面部よりも厚くするとともに、背表紙部に形成したスリットの両側端部の開口をリングの肉厚に対応させ且つ両側端部間を盤面部に対応させて両側端部の開口よりも幅狭に開口させることで、このスリットに対してリングを起立姿勢で保持するように構成してある。ここでスリットの開口長さは、リングの直径よりも短く設定してあるので、リングはスリットに挟まった通常の状態よりも深く係合することはない。一方、紙葉類の側縁部には、反綴り側に向けて切り込みを形成するとともに、その切り込みの終端部にリングの周縁部の肉厚に対応させた開口を形成し、盤面部に切り込みを挿入することによって紙葉類を綴じるように構成している。そして、このようにリングを保持した背表紙部は、略全域が平らであるのが通例である。
【0004】
【発明が解決しようとする課題】
ところが、このようなファイルにおいて背表紙部が平らであると、リングとスリットとの係合関係は略一直線状であり、しかもリングの下半部分がスリットに挿入させた状態にあるため、リングに対してその肉厚方向に外力が加わるとリングが容易に倒れてしまうという不具合が生じやすい。また、平面的な背表紙部は肉厚方向に撓みが生じ易いので、リングがスリットから簡単に抜け落ちてしまうという不具合も有している。
【0005】
そこで本発明は、以上のような問題に鑑みて、上述のような構成のファイルにおいて、簡素な構成でありながら背表紙部のリングに対する安定した保持状態を維持できるようなものを提供することを主たる目的としている。
【0006】
【課題を解決するための手段】
すなわち、本発明のファイルは、表表紙部、裏表紙部及び背表紙部を連続的に有する表紙本体と、背表紙部の幅方向へ延びるように形成したスリットに挿入して起立姿勢で支持され紙葉類を係合させて綴じる盤状の綴じ具とを有するものであって、背表紙部をその高さ方向に沿って表表紙部及び裏表紙部の内面側へ凸形状となるように変形させた状態を保持する保持手段を具備していることを特徴とするものである。
【0007】
このような構成のファイルであれば、保持手段によって表表紙部及び裏表紙部の内面側に凸形状に保持された背表紙部のスリットに綴じ具が保持されることになる。すなわち、背表紙部と共に二次元的に変形されたスリットに綴じ具の盤面部が係合されるため、一次元的な直線状のスリットに綴じ具を保持する場合と比較して、綴じ具の肉厚方向への倒れを好適に防止することができる。また、二次元的に変形した状態を保持された背表紙部自体は、その肉厚方向への外力に対して強いものとなるため、綴じ具の抜け落ちも容易に防止することができるようになり、以上の結果、紙葉類の保持を確実に行い、且つ綴じ具の脱落も有効に防止できる使い勝手の優れたファイルを構成することが可能となる。
【0008】
ここで、スリットの開口長さを綴じ具の最大径よりも短く設定しておくと綴じ具の脱落防止を確実なものとできるのは、従来通りである。
【0009】
このように有用な保持手段は、表紙本体に取り付けられ該表紙本体とは別体をなす保持部材からなるものとすることで、背表紙部の変形を簡易に保持することができる。
【0010】
背表紙部の凸形状を容易に形成するためには、背表紙部の幅方向中央部に、該背表紙部の高さ方向に延びる折り曲げ線を形成し、この折り曲げ線に沿って背表紙部を表表紙部及び裏表紙部の内面側へ折り曲げ得るように構成することが好ましく、この場合、背表紙部を山形に変形させた状態を前記保持部材によって保持することになる。なお、背表紙部の凸形状は、前記山形の他にも、例えば断面視アーチ形、台形状、「M」字形など、種々のものとすることができる。
【0011】
簡素な構成の保持部材としては、背表紙部を挟んで表表紙部及び裏表紙部の外面側に取り付けるようにしたシート状をなす保持部材や、背表紙部の外面側に取り付けるようにしたシート状をなす保持部材を挙げることができる。
【0012】
特に、表紙本体と保持部材とが別体である場合、背表紙部の外面側から見れば凹形状となった背表紙部と保持部材との間の空間に別途の機能を付与するには、保持部材を背表紙部の外面側を覆う大きさを有するものとして、背表紙部と保持部材との間にポケット部を形成するとよい。この場合、保持部材の一部又は全部が、透明又は半透明であると、ポケット部に収容した物を、保持部材を通じて視認可能とすることができる。すなわち、例えばポケット部において保持部材の透明部又は半透明部と対応する部位に、紙葉類の表題などを表記した表示札を挿入し得るようにすることで、凹形状をなした背表紙部の外側にも表題等を表すことが可能となる。
【0013】
【発明の実施の形態】
以下、本発明の一実施形態を、図面を参照して説明する。
【0014】
図1及び図2に示す本実施形態のファイル1は、表紙本体2と綴じ具たるリング3とを基本的構成要素として備え、図3に示すような紙葉類6をリング3に係合させて綴じるようにしたものである。以下、各部の具体的構成について説明する。
【0015】
表紙本体2は、例えばA4,B5等の所定の規格及び紙葉類6の最大綴り枚数に対応して、表表紙部21、裏表紙部22、及び背表紙部23を一体且つ連続的に形成した合成樹脂製シートからなるものである。図4にこの表紙本体2の展開図を内面側から見た状態で示すように、表表紙部21と背表紙部23との境界部分、及び裏表紙部22と背表紙部23との境界部分は、他の部位よりも若干薄肉としてヒンジ機能を設け、その部位で折り曲げ可能としている。また、背表紙部23の幅方向中央部には、高さ方向に沿ってその周囲よりも若干薄肉とした一直線状の折り曲げ線23zを設け、この折り曲げ線23zに沿って背表紙部23自体を表表紙部21及び裏表紙部の内面21a、22a側へ山折りにできるようにしている。さらに、背表紙部23には、この折り曲げ線23zに跨って幅方向に延び厚み方向に貫通させた直線状のスリット23sを、高さ方向へ所定ピッチで複数形成しており、各スリット23sの両側端部23saを、スリット23sの主要部の開口幅よりも大きい径で半円形状をなすように開口させている。なお、表紙本体2は、合成樹脂の他にも紙製シートや金属製シートから構成することができ、また、それぞれ別体のシート材からなる表表紙部、裏表紙部、背表紙部を連続的に接合したものとしてもよい。
【0016】
リング3は、背表紙部23に形成した各スリット23sに挿入されるものであり、例えば合成樹脂一体成形により形成された円盤状をなし、その直径はスリット23sの開口長さ寸法よりも若干大きくしてある。特にリング3の周縁部31の肉厚は、図2、図3、及び図5に示すように、それよりも内側の閉じた盤面部32の肉厚よりも若干大きく設定している。すなわち、盤面部32の肉厚寸法は、スリット23sの開口幅寸法に略対応し、また周縁部31の肉厚はスリット23sの開口幅よりも大きく且つ両側端部23saの開口よりも若干小さい。なお、盤面部32の略中心部には丸い貫通孔が形成されているが、これは部材の軽量化や素材の少量化のためのものである。
【0017】
そして、図6(a)に示すように、リング3を背表紙部23の内面23a側からスリット23sに挿入すると、リング3の周縁部31の一部がスリット23sの両側端部23saを通過した位置で、スリット23sの間にリング3の盤面部32が挟まれて起立した姿勢でリング3が当該スリット23sに係合する。その状態からさらに、同図(b)に示すように、背表紙部23を折り曲げ線23zに沿って内面23a側へ凸形状すなわち山形に折り曲げて変形したうえで、その変形させた背表紙部23の形状を保持する保持手段としての機能を有する保持部材4によって維持するようにしている。そしてこのように内側へ凸となった背表紙部23の形状は、同図(c)に示すように、表表紙部21及び裏表紙部22又はそれらの何れか一方を、背表紙部23に対して折り曲げた場合にも変わることなく維持される。
【0018】
ここで保持部材4は、透明又は半透明の合成樹脂製シート材からなるものであり、表紙本体2の外面側、具体的には背表紙23に跨って表表紙部21と裏表紙部22の外面21b、22bに取り付けられる。この保持部材4は、背表紙部23よりも幅広な長方形シート状をなすものであり、長手方向に沿った両側端部41を、表表紙部21及び裏表紙部22のそれぞれ背表紙部23と連続する端部に溶着等の接着又はリベットを用いる等の適宜の手段により取り付けている。したがって、図1、図2及び図6(b)、(c)に示すように、背表紙部23の外面23bと保持部材4の内面4aとの間には、断面視概略二等辺三角形状をなす空間が、背表紙部23の高さ方向に連続的に形成されることになり、この空間を本実施形態ではポケット部Pとしている。そして、このポケット部Pには、図1に示すように、綴じ込んだ紙葉類6の表題等を記した例えば長方形状の紙や樹脂製等の表示札5を挿入することで、保持部材4に保持的な背表紙としての機能を発揮させるとともに、透明又は半透明の保持部材4を通じてポケット部P内の表示札5の表記が外部から視認し得るようにしている。なお、表示札5は、適宜の手段によってポケット部P内で保持される用にしておくとよいが、そのためには例えば、表示札5を保持部材4の内面側に貼り付ける方法、表示札5の側縁部を表表紙部21及び裏表紙部22と保持部材4の側縁部41との間に挟み込む方法、表表紙部21及び裏表紙部22へ保持部材4と同時に取り付ける方法などを採用することができる。
【0019】
ここで、紙葉類6のファイル1への綴り方について簡単に説明する。図3に示すように、紙葉類6の綴り側の縁部6aに沿ってその縁部6aから反綴り側の縁部へ向けて短い切り込み61をリング3と略同一のピッチで形成しておくとともに、その切り込み61の終端部61aを前記スリット23sの端部23saと同様に概略半円弧状に開口しておく。そして、紙葉類6の綴り側の縁部6aを撓ませるようにして切り込み61を開きながらリング3に斜め上方から引っ掛けると、切り込み61がリング3の盤面部32と係合するとともに、切り込み61の終端部61aが周縁部31と係合する。この状態では、紙葉類6を半綴り方向へ引っ張っても、切り込み61の終端部61aがリング3の周縁部31と係合しているためリング3から外れることはないが、上述した綴り方と逆の操作すなわち紙葉類6の綴り側の縁部6aを捲るようにすると、紙葉類6をリング3から簡単に外すことができる。なお、紙葉類6としては、用紙類や、内部に用紙類等を収容できる袋体等を適用することができる。
【0020】
以上のように、本実施形態のファイル1によれば、背表紙部23を内側へ凸形状である山形をなすように変形させた状態を、表紙本体2とは別体の保持部材4によって恒常的に維持するようにしているため、背表紙部23のスリット23sに起立姿勢で挿入したリング3を極めて安定的に保持することができる。すなわち、リング3の盤面部32が二次元的に折り曲げられたスリット23s内に挟まれた状態にあり、リング3の周縁部31がスリット23sの両側端部23saに嵌まった状態にあるため、リング3の肉厚方向への倒れをスリット23sによって防止できる。さらに、背表紙23自体も角度がついて撓みにくい形状となっていることから、リング3の抜け落ちも確実に防止することができる。したがって、リング3を表紙本体2上に安定させるとともに、紙葉類6をもリング3に安定して綴じ込むことができる、極めて使い勝手の優れたファイル1とすることが可能である。また、内面側へ山形に変形させた背表紙部23と、背表紙部23を跨いで表表紙部21及び裏表紙部22に固定した保持部材4との間に形成されるポケット部Pを利用して、そのポケット部P内に表示札5を挿入可能とし、透明又は半透明の保持部材4を通じて表示札5の表記を外方から視認できるようにしているため、外部から見える位置にある保持部材4を背表紙部の代用として、従来のファイルと同様の使い方をすることができる。
【0021】
なお、上記実施形態では、変形させた背表紙部の形状を内面側に凸となる山形をなすものとしたが、これに限らず例えば図7に示す変形例のように、背表紙部23の幅方向中央部における折り曲げ線23zに加えてその両側方にもさらに折り曲げ線23yを形成し、背表紙部23の両側端部側が折り曲げた表表紙部21及び裏表紙部22と略直角となるようにしてもよい。この場合、折り曲げ線23z上の任意の部位を頂点として内面側に凸となる断面視三角形状に背表紙部23が変形されるが、保持部材140は、その内面側を背表紙部23の外面23bにおける両側端部に外方から取り付けられることになる。そして、この変形例の場合にも、背表紙部23と保持部材140との間には、表示札等を挿入し得るポケット部P’が形成されることになる。また、この変形例以外にも、背表紙部23を内面側にアーチ形や台形状等の適宜の形状に変形させ、その形状を保持部材によって保持するようにすることができる。
【0022】
さらに、背表紙部の変形させた形状を保持する保持手段としては、上述した一枚のシート状の保持部材以外にも、複数枚のシート状の保持部材を間欠的に表し本体に取り付けるようにしたものや、紐状をなす保持部材を表紙本体に取り付けるようにしたものなど、適宜のものを採用することができ、さらにいえば、表紙本体の一部を舌片状に切りあける等してそれを保持手段として利用することもできる。その他、綴じ具を円形以外の盤状をなすものとするなど、各部の具体的構成についても上記実施形態や変形例に限られるものではなく、本発明の趣旨を逸脱しない範囲で種々変形が可能である。
【0023】
【発明の効果】
本発明は、以上に詳述したように、表紙本体の背表紙部を、表表紙部及び裏表紙部の内面側に凸形状をなすように変形させ、この変形した背表紙部の形状を保持手段によって保持するように構成したものであり、背表紙部に形成したスリットに盤状の綴じ具を係合させている。このため、盤状の綴じ具が背表紙部と共に凸形状に変形したスリットと二次元的に係合することになり、綴じ具の肉厚方向への倒れが適正に防止される。また、保持手段に保持された背表紙部が変形した形状から開くことがなく、背表紙部が平面的である場合と比べて、背表紙部自体の歪みや撓みに対する対抗力も大きくなるため、綴じ具がスリットから抜け落ちてしまうこともない。したがって、綴じ具に綴じ込んだ紙葉類を正確に捲ることができ、しかも紙葉類が簡単には脱落することがないという、極めて使用感の優れたファイルを提供することができる。また、保持手段と背表紙部との間に形成されるポケット部に表示札等を挿入すれば、従来のファイルと同様に、ファイルの背に表題等を表示することもできる。

TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a file in which paper sheets are bound to a binding tool having a disk shape.
[0002]
[Prior art]
Conventionally, as a type of file for binding sheets, a cover body having a front cover part, a back cover part, and a back cover part, and a disk shape such as a disk shape in a slit formed in the back cover part. One or a plurality of rings serving as a binding tool is provided, and a cut formed in a binding side edge of a paper sheet is inserted into and engaged with a board surface of the ring.
[0003]
In such a file, the thickness of the peripheral edge of the ring is made thicker than the inner surface of the ring, and the openings at both ends of the slit formed in the spine are made to correspond to the thickness of the ring and both sides are formed. The ring is held in an upright position with respect to the slit by opening the end portion narrower than the opening at both end portions corresponding to the board surface portion. Here, since the opening length of the slit is set shorter than the diameter of the ring, the ring does not engage more deeply than in a normal state sandwiched between the slits. On the other hand, a notch is formed in the side edge of the paper sheet toward the reverse binding side, and an opening corresponding to the thickness of the peripheral portion of the ring is formed at the end of the notch, and the notch is formed in the board surface. Is inserted so as to bind paper sheets. The spine portion holding the ring in this manner is generally flat over substantially the entire area.
[0004]
[Problems to be solved by the invention]
However, in such a file, if the spine is flat, the engagement between the ring and the slit is substantially linear, and the lower half of the ring is inserted into the slit. On the other hand, when an external force is applied in the thickness direction, the ring is likely to fall down easily. In addition, since the flat spine portion tends to bend in the thickness direction, there is also a disadvantage that the ring easily falls out of the slit.
[0005]
Accordingly, the present invention has been made in view of the above-described problems, and provides a file having the above-described configuration that can maintain a stable holding state with respect to the ring of the spine portion while having a simple configuration. Its primary purpose.
[0006]
[Means for Solving the Problems]
That is, the file of the present invention is supported in an upright posture by being inserted into a cover body having a front cover portion, a back cover portion and a spine portion continuously, and a slit formed to extend in the width direction of the spine portion. A disc-shaped binding tool that engages and binds paper sheets so that the spine is convex toward the inner surface of the front cover and the back cover along the height direction. It has a holding means for holding the deformed state.
[0007]
In the case of a file having such a configuration, the binding device is held in the slit of the spine portion held in a convex shape on the inner surface side of the front cover portion and the back cover portion by the holding means. That is, since the board surface of the binding device is engaged with the two-dimensionally deformed slit together with the spine, the binding device of the binding device is compared with the case where the binding device is held in the one-dimensional linear slit. Falling in the thickness direction can be suitably prevented. In addition, the spine portion itself, which is held in a two-dimensionally deformed state, is strong against external force in the thickness direction, so that the binding tool can be easily prevented from falling off. As a result, it is possible to form a file having excellent usability that can securely hold paper sheets and can effectively prevent the falling off of the binding tool.
[0008]
Here, if the opening length of the slit is set shorter than the maximum diameter of the binding device, it is possible to reliably prevent the binding device from falling off, as in the conventional case.
[0009]
Since the useful holding means is constituted by a holding member attached to the cover body and formed separately from the cover body, the deformation of the spine can be easily held.
[0010]
In order to easily form the convex shape of the spine portion, a folding line extending in the height direction of the spine portion is formed at the center in the width direction of the spine portion, and the spine portion along the folding line is formed. Is preferably configured to be able to be bent toward the inner surface side of the front cover part and the back cover part. In this case, the state in which the spine part is deformed into a mountain shape is held by the holding member. The convex shape of the spine portion may be various shapes other than the mountain shape, such as an arch shape in cross section, a trapezoidal shape, and an “M” shape.
[0011]
As a holding member having a simple configuration, a sheet-shaped holding member that is attached to the outer surface side of the front cover portion and the back cover portion with the spine portion therebetween, and a sheet that is attached to the outer surface side of the spine portion Holding member in the shape of a sphere.
[0012]
In particular, when the cover body and the holding member are separate bodies, in order to provide a separate function to the space between the spine portion and the holding member that are concave when viewed from the outer surface side of the spine portion, The holding member may be large enough to cover the outer surface of the spine portion, and a pocket may be formed between the spine portion and the holding member. In this case, if a part or the whole of the holding member is transparent or translucent, the object accommodated in the pocket portion can be made visible through the holding member. That is, for example, in the pocket portion, a display tag describing a title of a paper sheet or the like can be inserted into a portion corresponding to the transparent portion or the translucent portion of the holding member, so that a spine portion having a concave shape is formed. , Etc., can be displayed outside the box.
[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[0014]
The file 1 of the present embodiment shown in FIGS. 1 and 2 includes a cover body 2 and a ring 3 serving as a binding device as basic components, and a paper sheet 6 as shown in FIG. It is intended to be bound. Hereinafter, a specific configuration of each unit will be described.
[0015]
The cover body 2 integrally and continuously forms a cover part 21, a back cover part 22, and a back cover part 23 in accordance with predetermined standards such as A4 and B5 and the maximum number of sheets to be sewn. Of a synthetic resin sheet. FIG. 4 shows a developed view of the cover body 2 as viewed from the inner side, where a boundary portion between the front cover portion 21 and the spine portion 23 and a boundary portion between the back cover portion 22 and the spine portion 23 are shown. Is provided with a hinge function that is slightly thinner than other parts, and can be bent at that part. In the center of the spine portion 23 in the width direction, a straight folding line 23z which is slightly thinner than the periphery thereof is provided along the height direction, and the spine portion 23 itself is formed along the folding line 23z. The front cover portion 21 and the back cover portion can be folded in a mountain direction toward the inner surfaces 21a and 22a. Further, in the spine 23, a plurality of linear slits 23s extending in the width direction and extending in the thickness direction across the bending line 23z are formed at a predetermined pitch in the height direction. Both side ends 23sa are opened so as to form a semicircular shape with a diameter larger than the opening width of the main part of the slit 23s. The cover body 2 can be made of a paper sheet or a metal sheet in addition to the synthetic resin, and a cover part, a back cover part, and a spine part made of a separate sheet material are continuously formed. It is good also as what was joined together.
[0016]
The ring 3 is inserted into each of the slits 23s formed in the spine 23, and has a disk shape formed by, for example, synthetic resin integral molding, and has a diameter slightly larger than the opening length of the slit 23s. I have. In particular, as shown in FIGS. 2, 3 and 5, the thickness of the peripheral edge portion 31 of the ring 3 is set to be slightly larger than the thickness of the closed board surface portion 32 inside it. That is, the thickness of the board surface portion 32 substantially corresponds to the opening width of the slit 23s, and the thickness of the peripheral portion 31 is larger than the opening width of the slit 23s and slightly smaller than the openings of both side end portions 23sa. A round through-hole is formed at a substantially central portion of the board surface portion 32 for the purpose of reducing the weight of the member and the amount of the material.
[0017]
Then, as shown in FIG. 6A, when the ring 3 is inserted into the slit 23s from the inner surface 23a side of the spine 23, a part of the peripheral edge 31 of the ring 3 has passed through both side ends 23sa of the slit 23s. At this position, the ring 3 engages with the slit 23s in an upright posture with the board surface portion 32 of the ring 3 sandwiched between the slits 23s. From this state, as shown in FIG. 2B, the spine 23 is bent and deformed along the folding line 23z toward the inner surface 23a in a convex shape, that is, a mountain shape, and the deformed spine 23 is deformed. Is maintained by a holding member 4 having a function as a holding means for holding the shape of. The shape of the spine 23 protruding inward as described above is such that the front cover 21 and the back cover 22 or one of them is formed into the spine 23 as shown in FIG. On the other hand, it is maintained unchanged even when bent.
[0018]
Here, the holding member 4 is made of a transparent or translucent synthetic resin sheet material, and is formed on the outer surface side of the cover body 2, specifically, over the spine 23, between the cover 21 and the back cover 22. It is attached to the outer surfaces 21b and 22b. The holding member 4 is in the form of a rectangular sheet wider than the spine portion 23, and has both side end portions 41 along the longitudinal direction, and the spine portion 23 of the front cover portion 21 and the back cover portion 22. It is attached to a continuous end by an appropriate means such as adhesion such as welding or using a rivet. Therefore, as shown in FIGS. 1 and 2 and FIGS. 6B and 6C, a substantially isosceles triangular cross section is formed between the outer surface 23 b of the spine 23 and the inner surface 4 a of the holding member 4. The space to be formed is formed continuously in the height direction of the spine 23, and this space is defined as a pocket P in the present embodiment. As shown in FIG. 1, a display member 5 made of, for example, rectangular paper or resin is inserted into the pocket portion P, and the title of the bound paper sheet 6 is inserted into the pocket member P. In addition to the function of the spine 4 as a retaining spine, the notation of the display tag 5 in the pocket portion P can be visually recognized from outside through the transparent or translucent holding member 4. The display tag 5 may be held in the pocket portion P by an appropriate means.

Here, how to spell the paper sheet 6 into the file 1 will be briefly described. As shown in FIG. 3, short cuts 61 are formed at substantially the same pitch as the ring 3 along the edge 6 a on the spelling side of the paper sheet 6 from the edge 6 a to the edge on the non-spelling side. At the same time, the end portion 61a of the cut 61 is opened in a substantially semicircular shape like the end 23sa of the slit 23s. When the sheet 6 is hooked on the ring 3 obliquely from above while opening the notch 61 so as to bend the spelling side edge 6 a of the paper sheet 6, the notch 61 engages with the board surface portion 32 of the ring 3 and the notch 61. End portion 61a engages with the peripheral edge portion 31. In this state, even if the paper sheet 6 is pulled in the semi-spelling direction, the end portion 61a of the cut 61 does not come off the ring 3 because the end portion 61a is engaged with the peripheral edge portion 31 of the ring 3. If the reverse operation is performed, that is, the edge 6a on the spelling side of the paper sheet 6 is turned, the paper sheet 6 can be easily removed from the ring 3. In addition, as the paper sheet 6, a paper sheet or a bag body capable of storing paper sheet or the like can be applied.

As described above, according to the file 1 of the present embodiment, the state in which the spine portion 23 is deformed so as to form an inwardly convex mountain shape is constantly maintained by the holding member 4 separate from the cover body 2. The ring 3 inserted in the upright posture into the slit 23s of the spine 23 can be held extremely stably. That is, since the board surface portion 32 of the ring 3 is sandwiched between the slits 23s that are bent two-dimensionally, and the peripheral portion 31 of the ring 3 is fitted to both side end portions 23sa of the slit 23s, The fall of the ring 3 in the thickness direction can be prevented by the slit 23s. Further, since the spine 23 itself has an angle and is hardly bent, the ring 3 can be reliably prevented from falling off. Accordingly, it is possible to stabilize the ring 3 on the cover main body 2 and stably bind the paper sheets 6 to the ring 3, and it is possible to provide the file 1 with excellent usability. In addition, a pocket portion P formed between the spine portion 23 deformed inwardly into an angle and the holding member 4 fixed to the front cover portion 21 and the back cover portion 22 across the spine portion 23 is used. Then, the display tag 5 can be inserted into the pocket portion P, and the notation of the display tag 5 can be visually recognized from the outside through the transparent or translucent holding member 4, so that the display tag 5 can be held at a position visible from the outside. The member 4 can be used in the same manner as a conventional file, instead of the spine.

In the above-described embodiment, the shape of the deformed spine portion is formed into a mountain shape that is convex toward the inner surface side. However, the present invention is not limited to this. For example, as in a modified example illustrated in FIG. In addition to the bending line 23z at the center in the width direction, bending lines 23y are further formed on both sides thereof so that both end sides of the backstrip 23 are substantially perpendicular to the bent front cover 21 and the back cover 22. It may be. In this case, the backstrip portion 23 is deformed into a triangular cross-sectional shape that is convex on the inner surface side with an arbitrary portion on the folding line 23z as the vertex. 23b will be attached from both sides to both ends. Also in the case of this modification, a pocket portion P ′ into which a display tag or the like can be inserted is formed between the spine 23 and the holding member 140. In addition to this modified example, the spine portion 23 can be deformed into an appropriate shape such as an arch shape or a trapezoidal shape on the inner surface side, and the shape can be held by the holding member.
[0022]
Further, as holding means for holding the deformed shape of the spine portion, in addition to the above-described one sheet-like holding member, a plurality of sheet-like holding members may be intermittently represented and attached to the main body. Or a suitable one such as one in which a string-shaped holding member is attached to the cover body, and more specifically, by cutting a part of the cover body into a tongue-like shape. It can also be used as holding means. In addition, the specific configuration of each part is not limited to the above-described embodiment and modified examples, such as making the binding tool a disk shape other than a circle, and various modifications can be made without departing from the spirit of the present invention. It is.

【The invention's effect】
As described in detail above, the present invention deforms the spine portion of the cover body so as to form a convex shape on the inner surface side of the front cover portion and the back cover portion, and retains the shape of the deformed spine portion. It is configured to be held by means, and a disc-shaped binding tool is engaged with a slit formed in the spine portion. For this reason, the disc-shaped binding tool is two-dimensionally engaged with the slit deformed into a convex shape together with the spine, and the binding tool is properly prevented from falling in the thickness direction. Further, since the spine portion held by the holding means does not open due to the deformed shape, and the spine portion itself has a greater resistance to distortion and bending as compared to the case where the spine portion is planar, the The tool does not fall out of the slit. Therefore, it is possible to provide a file having an excellent usability, in which the paper sheets bound to the binding device can be accurately turned, and the paper sheets do not easily fall off. If a display tag or the like is inserted in a pocket formed between the holding means and the spine, a title or the like can be displayed on the back of the file as in the case of a conventional file.
