Description

本発明は、樹脂材料からなるシート材を用いて形成された表紙と裏表紙との間に書類を収納する書類収納ファイルに関する。 The present invention relates to a document storage file that stores a document between a front cover and a back cover formed by using a sheet material made of a resin material.

従来より、樹脂材料からなるシート材を用いて形成された書類収納ファイル（ホルダ）として、様々な構成が提案されている。簡素なものでは、シート材を折曲した後、一辺を溶着して表紙と裏表紙との間に書類を収納する構成が知られている（特許文献１参照）。また、このような構成をベースとして、収納する書類の落下防止を図るための押え片を備える構成も知られている（特許文献２参照）。 Conventionally, various configurations have been proposed as a document storage file (holder) formed by using a sheet material made of a resin material. As a simple one, a configuration is known in which after bending a sheet material, one side is welded and a document is stored between a front cover and a back cover (see Patent Document 1). Further, based on such a configuration, there is also known a configuration including a pressing piece for preventing a stored document from falling (see Patent Document 2).

しかし、上記の特許文献１：実用新案登録第３０２８８９３号公報、特許文献２：特開２００１−２３２９８１号公報に例示される構成においては、書類を収納するスペースが一つであるため、内容や目的等に応じて複数の書類もしくは書類群（以下、単に「書類」と称する）を仕訳して収納することができないという課題があった。このような課題の解決を図るものとして、例えば、複数の収納部を設けることにより、複数の書類を仕訳して収納することが可能な構成が知られている（特許文献３：実用新案登録第３０３８７５２号公報参照）。 However, in the configurations illustrated in the above-mentioned Patent Document 1: Utility Model Registration No. 3028893 and Patent Document 2: Japanese Patent Application Laid-Open No. 2001-232981, there is only one space for storing documents, so the content and purpose are There is a problem that a plurality of documents or a group of documents (hereinafter, simply referred to as "documents") cannot be sorted and stored according to the situation. As a solution to such a problem, for example, a configuration is known in which a plurality of documents can be sorted and stored by providing a plurality of storage units (Patent Document 3: Utility Model Registration No. 1). (See Japanese Patent No. 3038752).

製造コストの観点からすれば特許文献１に例示されるような折曲・溶着した単純な構成が有利である。また、さらに収納した書類の落下防止を図ることが可能な機構が追加された特許文献２に例示されるような構成であっても、大幅なコスト増加は生じない。しかしながら、これらの構成では、複数の書類を仕訳して収納することができない。一方、複数の書類を仕訳して収納することを可能とするために、特許文献３に例示されるような複数枚のシートを用いて複数の収納部を設ける構成とした場合には、原材料コストおよび加工コストのいずれもが増加してしまうため、製造コストが大幅に増加してしまうという課題が生じ得る。 From the viewpoint of manufacturing cost, the simple structure of bending and welding as illustrated in Patent Document 1 is advantageous. Further, even with the configuration illustrated in Patent Document 2 in which a mechanism capable of preventing the stored documents from falling is added, a significant increase in cost does not occur. However, with these configurations, a plurality of documents cannot be sorted and stored. On the other hand, in the case where a plurality of sheets are used to form a plurality of storage units so that a plurality of documents can be sorted and stored, raw material costs can be reduced. In addition, both the manufacturing cost and the processing cost increase, which may cause a problem that the manufacturing cost significantly increases.

本発明は、上記事情に鑑みてなされ、きわめて簡素な構成により製造コストの増加を抑えつつ、複数の書類を仕訳して収納することが可能な書類収納ファイルを提供することを目的とする。 The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a document storage file capable of sorting and storing a plurality of documents while suppressing an increase in manufacturing cost with an extremely simple configuration.

本発明は、以下に記載するような解決手段により、前記課題を解決する。 The present invention solves the above-mentioned problems by the following solution means.

本発明に係る書類収納ファイルは、樹脂材料からなるシート材を用い、少なくとも一辺が折曲もしくは溶着によって閉じられた表紙と裏表紙との間に書類を収納する書類収納ファイルであって、前記裏表紙は、前記閉じられた一辺と対向する位置の開口した一辺寄りの端部領域において、外縁部側に設けられた起点から内方側へ進んでから外縁部側に設けられた終点に戻る連続線で切込みが入れられて、該起点と該終点とを結ぶ線を基線として、該起点および該終点から最も離れた位置である頂部が前記表紙側へ向かう方向に、起立可能に形成されている主保持部を有し、前記主保持部は、前記開口した一辺と平行に所定の間隔をあけて複数個並設されており、前記複数個の主保持部は、並設されている順に前記基線と前記頂部との間の長さ寸法が段階的に小さくもしくは大きくなるように形成されていることを要件とする。 A document storage file according to the present invention is a document storage file that uses a sheet material made of a resin material and stores a document between a front cover and a back cover whose at least one side is closed by bending or welding. In the end area near the one side of the opening where the cover sheet faces the closed one side, the cover sheet continuously advances from the starting point provided on the outer edge side to the inner side and then returns to the end point provided on the outer edge side. A notch is formed by a line, and with the line connecting the starting point and the ending point as a base line, the top part that is the farthest position from the starting point and the ending point is formed so as to be able to stand in the direction toward the cover side. A plurality of main holding parts, the main holding parts are arranged in parallel at a predetermined interval in parallel with the opened one side, and the plurality of main holding parts are arranged in the order in which they are arranged.

Hereinafter, the first embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic diagram (front view) showing an example of a document storage file 1 according to the present embodiment. Further, FIG. 2 is a schematic view (front view) in a state where the cover 2 of the document storage file 1 is opened (turned over). Further, FIG. 3 is a perspective view for explaining the configuration (action) of the main holding unit 20 of the document storage file 1. In the text, for convenience, the description will be given using the words on the left side, the right side, the upper side, and the lower side at the positions shown in FIG. In addition, in all the drawings for explaining the embodiments, members having the same function are designated by the same reference numeral, and the repeated description thereof may be omitted.

書類収納ファイル１は、図１、図２に示すように、シート材からなる表紙２と裏表紙３との間に書類を挟み込んで収納する収納具である。本実施形態においては、１枚の矩形のシート材が中央で折曲されることによって、閉じられた一辺（図１の左辺）１１により連結された表紙２および裏表紙３が形成されている。これと共に、当該左辺１１と対向する位置には、書類の出し入れ部となる開口した一辺（図１の右辺）１３が形成されている。あるいは、変形例として、２枚の矩形のシート材が溶着もしくは接着されることによって、閉じられた一辺（左辺）１１が形成される構成としてもよい（不図示）。なお、シート材には、ポリプロピレン等の樹脂材料が用いられているが、透明度、色彩、模様等については特に限定されるものではない。 As shown in FIGS. 1 and 2, the document storage file 1 is a storage device that stores a document by sandwiching a document between a front cover 2 and a back cover 3 made of a sheet material. In the present embodiment, one rectangular sheet material is bent at the center to form the front cover 2 and the back cover 3 which are connected by the closed one side (the left side in FIG. 1) 11. At the same time, an open side (right side in FIG. 1) 13 serving as a document loading/unloading portion is formed at a position facing the left side 11. Alternatively, as a modified example, the closed one side (left side) 11 may be formed by welding or adhering two rectangular sheet materials (not shown). A resin material such as polypropylene is used for the sheet material, but the transparency, color, pattern, etc. are not particularly limited.

一方、上方の辺（図１の上辺）１４は、書類の出し入れを容易にするために、開口した辺として形成されている。ただし、これに限定されず、閉じられた辺としてもよい（不図示）。また、下方の辺（図１の下辺）１２は、書類の落出を防止するために、閉じられた辺として形成されている。ただし、これに限定されず、開口した辺としてもよい（不図示）。なお、一例として、下辺１２は溶着（熱溶着）によって形成されているが、これに限定されるものではなく、接着等によって形成される構成としてもよい。 On the other hand, the upper side (upper side of FIG. 1) 14 is formed as an open side to facilitate the taking in and out of documents. However, it is not limited to this, and may be a closed side (not shown). The lower side (lower side of FIG. 1) 12 is formed as a closed side to prevent the document from falling out. However, the present invention is not limited to this and may be an open side (not shown). Note that, as an example, the lower side 12 is formed by welding (heat welding), but the present invention is not limited to this and may be formed by adhesion or the like.

ここで、本実施形態に特徴的な構成として、裏表紙３には、書類の端部を挟み込むように保持する主保持部２０が設けられている。より具体的には、図２、図３に示すように、主保持部２０は、裏表紙３の右辺１３（１３Ｂ）寄りの端部領域において、外縁部３ａ側に設けられた起点２０ａから内方３ｂ側へ進んでから外縁部３ａ側に設けられた終点２０ｂに戻る連続線（切込み線）２０ｃで切込みが入れられることによって、当該連続線（切込み線）２０ｃと、起点２０ａと終点２０ｂとを結ぶ基線２０ｄとで囲まれる領域として形成されている。この構成によれば、基線２０ｄの位置を支点として、基線２０ｄの位置から最も離れた位置となる頂部２０ｅが表紙２側へ向かう方向に起立する動作が可能となる。したがって、表紙２と裏表紙３との間に書類を挟み込んだ後、主保持部２０を起立させてから戻すように動作させることによって、主保持部２０で書類の端部を挟み込んで保持することができる。 Here, as a characteristic configuration of this embodiment, the back cover 3 is provided with a main holding portion 20 that holds the end portion of the document so as to sandwich it. More specifically, as shown in FIGS. 2 and 3, the main holding portion 20 is located inside the starting point 20a provided on the outer edge portion 3a side in the end region of the back cover 3 near the right side 13 (13B). The continuous line (cut line) 20c, the starting point 20a, and the end point 20b are formed by making a cut on the continuous line (cut line) 20c that proceeds to the side 3b and then returns to the end point 20b provided on the outer edge 3a side. Is formed as a region surrounded by a base line 20d that connects the two. With this configuration, it is possible to perform an operation in which the top portion 20e, which is the farthest position from the position of the base line 20d, stands up in the direction toward the cover sheet 2 with the position of the base line 20d as the fulcrum. Therefore, after the document is sandwiched between the front cover 2 and the back cover 3, the main holding unit 20 is operated so as to stand up and then returned so that the main holding unit 20 sandwiches and holds the end of the document. You can

そのため、主保持部２０の配設位置は、収納する書類の対応寸法に適合するように設定されている。具体的には、閉じられた左辺１１と基線２０ｄとの間の長さ寸法が、収納する書類の対応寸法よりも大きく、且つ、閉じられた左辺１１と頂部２０ｅとの間の長さ寸法が、収納する書類の対応寸法よりも小さくなるように設けられている。 Therefore, the arrangement position of the main holding portion 20 is set so as to match the corresponding size of the documents to be stored. Specifically, the length dimension between the closed left side 11 and the base line 20d is larger than the corresponding dimension of the documents to be stored, and the length dimension between the closed left side 11 and the top portion 20e is , Smaller than the corresponding size of the documents to be stored.

上記の構成を備える主保持部２０は、開口した右辺１３（１３Ｂ）に沿って（すなわち、右辺１３（１３Ｂ）と平行の方向に）所定の間隔をあけて複数個並設されている（符号２０Ａ、２０Ｂ、２０Ｃで示す）。この構成によれば、表紙２と裏表紙３とで挟まれる単一の空間内に複数の書類を仕訳して収納することが可能となる。本実施形態においては、主保持部２０が３個（２０Ａ、２０Ｂ、２０Ｃ）である場合を例に挙げて説明するが、２個もしくは４個以上としてもよい（不図示）。 A plurality of main holding portions 20 having the above configuration are arranged side by side at a predetermined interval along the opened right side 13 (13B) (that is, in the direction parallel to the right side 13 (13B)) (reference numeral). 20A, 20B, 20C). According to this configuration, it is possible to sort and store a plurality of documents in a single space sandwiched between the front cover 2 and the back cover 3. In the present embodiment, the case where the number of the main holding portions 20 is three (20A, 20B, 20C) will be described as an example, but the number may be two or four or more (not shown).

また、主保持部２０（２０Ａ、２０Ｂ、２０Ｃ）が設けられる位置に対応して、裏表紙３の外縁部３ａには、外方側へ突出させたインデックス部２２（２２Ａ、２２Ｂ、２２Ｃ）が設けられている。これにより、仕訳して収納した複数の書類の内容をそれぞれ表示（記載）することができるため、書類の管理を確実に行うことができる。 In addition, index portions 22 (22A, 22B, 22C) protruding outward are provided on the outer edge portion 3a of the back cover 3 at positions corresponding to the positions where the main holding portions 20 (20A, 20B, 20C) are provided. It is provided. As a result, the contents of a plurality of documents that have been journalized and stored can be displayed (written), so that the documents can be managed reliably.

ここで、具体的な収納方法について、図４〜図６を用いて説明する。
先ず、図４（ａ）に示すように、第１の書類（書類群）Ｐ１を表紙２と裏表紙３との間に収納する。次いで、図４（ｂ）に示すように、閉じられた下辺１２側から１番目の第１の主保持部２０（２０Ａ）を第１の書類Ｐ１（ここでは最上面の書類）よりも上まで起立させてから戻すことによって、第１の書類Ｐ１の端部（ここでは右端部）を挟み込んで保持を行う。 Here, a specific storage method will be described with reference to FIGS. 4 to 6.
First, as shown in FIG. 4A, the first document (document group) P1 is housed between the front cover 2 and the back cover 3. Next, as shown in FIG. 4B, the first first main holding portion 20 (20A) from the closed lower side 12 side is positioned above the first document P1 (here, the uppermost document). By standing and then returning, the end (here, the right end) of the first document P1 is sandwiched and held.

次いで、図５（ａ）に示すように、第２の書類（書類群）Ｐ２を表紙２と先に第１の主保持部で保持された第１の書類Ｐ１（ここでは最上面の書類）との間に収納する。次いで、図５（ｂ）に示すように、閉じられた下辺１２側から２番目の第２の主保持部２０（２０Ｂ）を第２の書類Ｐ２（ここでは最上面の書類）よりも上まで起立させてから戻すことによって、第２の書類Ｐ２の端部（ここでは右端部）を挟み込んで保持を行う。 Next, as shown in FIG. 5A, the second document (document group) P2 and the first document P1 previously held by the first main holding unit on the cover 2 (here, the uppermost document). Store between and. Next, as shown in FIG. 5B, the second main holding portion 20 (20B), which is the second from the side of the closed lower side 12, is located above the second document P2 (here, the top document). By standing and then returning, the end portion (here, the right end portion) of the second document P2 is sandwiched and held.

次いで、図６（ａ）に示すように、第３の書類（書類群）Ｐ３を表紙２と先に第２の主保持部で保持された第２の書類Ｐ２（ここでは最上面の書類）との間に収納する。次いで、図６（ｂ）に示すように、閉じられた下辺側から３番目の第３の主保持部を第３の書類Ｐ３（ここでは最上面の書類）よりも上まで起立させてから戻すことによって、第３の書類Ｐ３の端部（ここでは右端部）を挟み込んで保持を行う。 Next, as shown in FIG. 6A, the third document (document group) P3 is attached to the cover 2 and the second document P2 previously held by the second main holding unit (here, the uppermost document). Store between and. Next, as shown in FIG. 6(b), the closed third third main holding portion from the lower side is raised up above the third document P3 (here, the uppermost document), and then returned. Thus, the end portion (here, the right end portion) of the third document P3 is sandwiched and held.

このように、上記構成による収納方法によれば、表紙２と裏表紙３との間に形成される単一空間において、複数の書類を仕訳して収納することが可能となる。すなわち、複数個の例として３個の主保持部２０（２０Ａ、２０Ｂ、２０Ｃ）を有する場合には、第１の書類Ｐ１が裏表紙３と第１の主保持部２０Ａとの間に仕訳して収納でき、第２の書類Ｐ２が第１の主保持部２０Ａと第２の主保持部２０Ｂとの間に仕訳して収納でき、第３の書類Ｐ３が第２の主保持部２０Ｂと第３の主保持部２０Ｃとの間に仕訳して収納できる。なお、図示を省略するが、第３の主保持部２０Ｃと表紙２との間に第４の書類を仕訳して収納することも構造上可能となっている。 As described above, according to the storage method having the above configuration, it is possible to sort and store a plurality of documents in a single space formed between the front cover 2 and the back cover 3. That is, in the case of having three main holding units 20 (20A, 20B, 20C) as a plurality of examples, the first document P1 is journalized between the back cover 3 and the first main holding unit 20A. The second document P2 can be stored by being journaled between the first main holding portion 20A and the second main holding portion 20B, and the third document P3 can be stored between the second main holding portion 20B and the second main holding portion 20B. It can be sorted and stored between the main holding unit 20C and the main holding unit 20C. Although illustration is omitted, it is structurally possible to sort and store the fourth document between the third main holding portion 20C and the cover 2.

したがって、複数の書類を収納するに際して、特許文献３に例示されるように複数のシートを溶着等して内部を仕切る構成を設ける必要がないため、原材料コストは増加せず、加工コストも主保持部の形成つまり切込み線の追加のみで対応でき、コスト増を抑制できるため、製造コストの増加という前述の課題の解決が可能となる。 Therefore, when accommodating a plurality of documents, it is not necessary to provide a structure for partitioning the inside by welding a plurality of sheets as exemplified in Patent Document 3, so that the raw material cost does not increase and the processing cost is mainly maintained. This can be dealt with only by forming a portion, that is, by adding a score line, and an increase in cost can be suppressed, so that the above-mentioned problem of an increase in manufacturing cost can be solved.

さらに、本実施形態に特徴的な構成として、複数個（ここでは３個）の主保持部２０（２０Ａ、２０Ｂ、２０Ｃ）は、閉じられた下辺１２側から並設されている順に基線２０ｄと頂部２０ｅとの間の長さ寸法が段階的に大きくなるように形成されている。具体的には、閉じられた下辺１２側から並設されている順に、１番目の第１の主保持部２０Ａの基線２０ｄと頂部２０ｅとの長さＬ１が最も小さく、２番目の第２の主保持部２０Ｂの基線２０ｄと頂部２０ｅとの長さＬ２が２番目に小さく、３番目の第３の主保持部２０Ｃの基線２０ｄと頂部２０ｅとの長さＬ３が最も大きくなるように構成されている。 Further, as a characteristic configuration of this embodiment, a plurality of (here, three) main holding portions 20 (20A, 20B, 20C) are provided with a base line 20d in the order arranged in parallel from the closed lower side 12 side. It is formed such that the length dimension between the top portion 20e and the top portion 20e gradually increases. Specifically, the length L1 between the base line 20d and the top portion 20e of the first first main holding portion 20A is the smallest in the order of being arranged in parallel from the closed lower side 12 side, and the second second The length L2 between the base line 20d and the top portion 20e of the main holding portion 20B is the second smallest, and the length L3 between the base line 20d and the top portion 20e of the third third main holding portion 20C is the largest. ing.

この構成によれば、第１の書類Ｐ１のみを保持する第１の主保持部２０Ａの長さＬ１は、保持書類の厚さが相対的に薄いため、相対的に小さく形成して、保持操作を容易に行えるようにしている。仮に、大きく形成してしまうと、閉じられた下辺１２に近い位置であって表紙２と裏表紙３との距離を大きく取る（開口する）ことができない位置であるため、保持操作が行い難いものとなる。一方、第１の書類Ｐ１、第２の書類Ｐ２、および第３の書類Ｐ３の全てを保持する第３の主保持部２０Ｃの長さＬ３は、保持書類の厚さが相対的に厚いため、相対的に大きく形成して、書類が厚い場合であっても確実に保持を行えるようにしている。仮に、小さく形成してしまうと、挟み込む領域が小さくなり、保持が不十分となってしまうため、書類の仕訳ができない、あるいは書類が落出してしまう等の不具合が生じ得る。なお、中間位置となる第２の主保持部２０Ｂの長さＬ２は、第１の主保持部２０Ａの長さＬ１と、第３の主保持部２０Ｃの長さＬ３との中間値に設定すればよい。 According to this configuration, the length L1 of the first main holding portion 20A that holds only the first document P1 is relatively small because the thickness of the held document is relatively small, and the holding operation is performed. To make it easy. If it is formed to be large, it is a position close to the closed lower side 12 and a position where the distance between the front cover 2 and the back cover 3 cannot be set large (opened), so that the holding operation is difficult to perform. Becomes On the other hand, the length L3 of the third main holding portion 20C that holds all of the first document P1, the second document P2, and the third document P3 is relatively thick because the held documents are relatively thick. It is made relatively large so that it can be held securely even if the document is thick. If it is formed small, the sandwiched area becomes small and the holding becomes insufficient, so that problems such as not being able to sort the document or dropping the document may occur. The length L2 of the second main holding portion 20B at the intermediate position may be set to an intermediate value between the length L1 of the first main holding portion 20A and the length L3 of the third main holding portion 20C. Good.

このように、収納作業（保持操作）を容易に行うために、複数個の主保持部２０（２０Ａ、２０Ｂ、２０Ｃ）は、閉じられた下辺１２側から並設されている順に基線２０ｄと頂部２０ｅとの間の長さ寸法が段階的に大きくなるように形成されていることが好ましい。ただし、図示を省略するが、下辺１２が開口した一辺として形成されている場合には、閉じられた下辺１２側から並設されている順に基線２０ｄと頂部２０ｅとの間の長さ寸法が段階的に小さくなるように形成してもよい。 In this way, in order to easily perform the storing operation (holding operation), the plurality of main holding portions 20 (20A, 20B, 20C) are arranged in parallel from the closed lower side 12 side in the order of the base line 20d and the top portion. It is preferable that the length between 20e and 20e is formed so as to increase stepwise. However, although illustration is omitted, when the lower side 12 is formed as an open side, the length dimension between the base line 20d and the top portion 20e is stepped in the order in which the lower side 12 is arranged side by side. You may form so that it may become small.

ここで、複数個の主保持部２０（２０Ａ、２０Ｂ、２０Ｃ）は、それぞれの基線２０ｄの位置が同一線上となるように配設されていることが好ましい。これによれば、複数の書類を仕訳して収納する際に、各書類の端部位置を揃えた状態で保持することできるため、整然とした状態での収納が可能となる。さらに、基線２０ｄの位置がばらつかないため、裏表紙３の外縁部３ａに設けられるインデックス部２２（２２Ａ、２２Ｂ、２２Ｃ）の形状（特に、横方向寸法）を統一することができ、且つ、裏表紙３の形状（特に、横方向寸法）をコンパクトに形成することができる。 Here, it is preferable that the plurality of main holding portions 20 (20A, 20B, 20C) are arranged such that the positions of the respective base lines 20d are on the same line. According to this, when a plurality of documents are sorted and stored, the end positions of the respective documents can be held in a aligned state, so that the documents can be stored in an orderly state. Furthermore, since the position of the base line 20d does not vary, the shape (in particular, the lateral dimension) of the index portion 22 (22A, 22B, 22C) provided on the outer edge portion 3a of the back cover 3 can be made uniform, and The shape of the back cover 3 (in particular, the lateral dimension) can be made compact.

More specifically, on the opened right side 13 (13B), the first main holding portion 20A is disposed at a position on the opened upper side 14 orthogonal to the right side 13 (13B). Further, in the opened right side 13 (13B), the second main holding portion 20B is disposed at a position on the closed lower side 12 side orthogonal to the right side 13 (13B) (the lower side is opened as described above. It may be a side). In addition, it is also possible to apply to a modification in which the main holding portions 20 are three or more (not shown).

ここで、第１の主保持部２０Ａは、基線２０ｄと頂部２０ｅとの長さＬ１が相対的に小さく形成されており、第２の主保持部２０Ｂは、基線２０ｄと頂部２０ｅとの長さＬ２が相対的に大きく形成されている。 Here, the first main holding portion 20A is formed such that the length L1 between the base line 20d and the top portion 20e is relatively small, and the second main holding portion 20B is formed in the length between the base line 20d and the top portion 20e. L2 is formed relatively large.

また、主保持部２０（２０Ａ、２０Ｂ）が設けられる位置に対応して、裏表紙３の外縁部３ａには、外方側へ突出させたインデックス部２２（２２Ａ、２２Ｂ）が設けられている。 Further, index portions 22 (22A, 22B) protruding outward are provided on the outer edge portion 3a of the back cover 3 corresponding to the positions where the main holding portions 20 (20A, 20B) are provided. ..

一方、本実施形態においては、表紙２に、補助保持部２６が１個設けられている。なお、一例として、補助保持部２６における基線２６ｄと頂部２６ｅとの長さＬ４は、第２の主保持部２０Ｂにおける基線２０ｄと頂部２０ｅとの長さＬ２と同じ長さに設定している。ただし、これに限定されるものではない。 On the other hand, in the present embodiment, the cover 2 is provided with one auxiliary holding portion 26. In addition, as an example, the length L4 between the base line 26d and the top portion 26e of the auxiliary holding portion 26 is set to be the same as the length L2 between the base line 20d and the top portion 20e of the second main holding portion 20B. However, it is not limited to this.

また、外縁部２ａが設けられる位置に対応して、表紙２の外縁部２ａには、外方側へ突出させたインデックス部３０が設けられている。 Further, the outer edge portion 2a of the cover 2 is provided with an index portion 30 protruding outward, corresponding to the position where the outer edge portion 2a is provided.

ここで、本実施形態に特徴的な構成として、表紙２に直交する方向（図９における紙面に直交する方向）に視て、第１の主保持部２０Ａ、補助保持部２６、第２の主保持部２０Ｂがその順に、上辺１４側から下辺１２側へ向かう方向に所定間隔をあけて配設される構成を有している。 Here, as a characteristic configuration of this embodiment, the first main holding portion 20A, the auxiliary holding portion 26, and the second main holding portion 20A when viewed in a direction orthogonal to the cover sheet 2 (direction orthogonal to the paper surface in FIG. 9). The holding portions 20B are arranged in that order at predetermined intervals in the direction from the upper side 14 side toward the lower side 12 side.

上記の構成によれば、書類の３分類、すなわち書類を３つに仕訳して収納することを好適に行うことができる。以下、収納動作について具体的に説明する。
先ず、図１１（ａ）に示すように、第１の書類（書類群）Ｐ１を表紙２と裏表紙３との間に収納する。次いで、図１１（ｂ）に示すように、上辺１４側の第１の主保持部２０（２０Ａ）を第１の書類Ｐ１（ここでは最上面の書類）よりも上まで起立させてから戻すことによって、第１の書類Ｐ１の端部（ここでは右端部）を挟み込んで保持を行う。 According to the above configuration, it is possible to preferably perform three classifications of documents, that is, to sort and store documents into three. Hereinafter, the storing operation will be specifically described.
First, as shown in FIG. 11A, the first document (document group) P1 is housed between the front cover 2 and the back cover 3. Then, as shown in FIG. 11(b), the first main holding portion 20 (20A) on the upper side 14 side is raised up above the first document P1 (here, the uppermost document) and then returned. Thus, the end portion (here, the right end portion) of the first document P1 is sandwiched and held.

次いで、図１２（ａ）に示すように、第２の書類（書類群）Ｐ２を表紙２と先に第１の主保持部で保持された第１の書類Ｐ１（ここでは最上面の書類）との間に収納する。このままの状態でも分類は可能であるが、落出防止を図るストッパとして機能させる観点からも、図１２（ｂ）に示すように、下辺１２側の第２の主保持部２０（２０Ｂ）を第２の書類Ｐ２（ここでは最上面の書類）よりも上まで起立させてから戻すことによって、第２の書類Ｐ２の端部（ここでは右端部）を挟み込んで保持を行う（このとき、同時に第１の書類Ｐ１の端部（ここでは右端部）も挟み込んで保持を行うこととなる）。 Then, as shown in FIG. 12A, the second document (document group) P2 and the first document P1 (here, the uppermost document) held by the first main holding unit in front of the cover 2 are attached. Store between and. Although the classification can be performed in this state, the second main holding portion 20 (20B) on the lower side 12 side is set to the first side as shown in FIG. 12(b) from the viewpoint of functioning as a stopper for preventing falling. The second document P2 (here, the topmost document) is erected up and returned to sandwich and hold the end (here, right end) of the second document P2 (at this time, simultaneously The end portion (here, the right end portion) of the first document P1 is also sandwiched and held).

次いで、図１３（ａ）に示すように、第３の書類（書類群）Ｐ３を表紙２と先に収納された状態の第２の書類Ｐ２（ここでは最上面の書類）との間に収納する。次いで、図１３（ｂ）に示すように、表紙２における補助保持部２６を第３の書類Ｐ３（ここでは最下面の書類）よりも下まで起立させてから戻すことによって、第３の書類Ｐ３の端部（ここでは右端部）を挟み込んで保持を行う。 Next, as shown in FIG. 13A, the third document (document group) P3 is stored between the cover 2 and the previously stored second document P2 (here, the uppermost document). To do. Next, as shown in FIG. 13B, the auxiliary holding portion 26 on the cover 2 is raised to a position lower than the third document P3 (here, the document on the bottom surface), and then returned to the third document P3. The end portion (here, the right end portion) is sandwiched and held.

このように、上記構成による収納方法によれば、表紙２と裏表紙３との間に形成される単一空間において、複数の書類を仕訳して収納することが可能となる。特に、２個の主保持部２０（２０Ａ、２０Ｂ）と補助保持部２６とを有する構成によって、第１の書類Ｐ１が裏表紙３と第１の主保持部２０Ａとの間に仕訳して収納でき、第２の書類Ｐ２が第１の主保持部２０Ａと補助保持部２６との間に仕訳して収納でき、第３の書類Ｐ３が補助保持部２６と表紙２との間に仕訳して収納できる。なお、前述の通り、第２の主保持部２０Ｂによって第２の書類Ｐ２を（同時に第１の書類Ｐ１も）保持させることによって、落出防止効果を得ることもできる。 As described above, according to the storage method having the above configuration, it is possible to sort and store a plurality of documents in a single space formed between the front cover 2 and the back cover 3. Particularly, due to the configuration having the two main holding portions 20 (20A, 20B) and the auxiliary holding portion 26, the first document P1 is sorted and stored between the back cover 3 and the first main holding portion 20A. Yes, the second document P2 can be sorted and stored between the first main holding unit 20A and the auxiliary holding unit 26, and the third document P3 can be sorted between the auxiliary holding unit 26 and the cover 2. Can be stored. As described above, by holding the second document P2 (and at the same time, the first document P1) by the second main holding portion 20B, it is possible to obtain the falling prevention effect.

したがって、特許文献３に例示されるように複数のシートを溶着等して内部を仕切る構成を設ける必要がないため、原材料コストは増加せず、加工コストも主保持部の形成つまり切込み線の追加のみで対応でき、コスト増を抑制できる。すなわち、きわめて簡素な構造によって、書類を３分類して仕訳可能な書類収納ファイルを好適に実現することが可能となる。 Therefore, since it is not necessary to provide a structure for partitioning the inside by welding a plurality of sheets as exemplified in Patent Document 3, the raw material cost does not increase, and the processing cost also increases the formation of the main holding portion, that is, the addition of the score line. It can be dealt with only by suppressing the cost increase. That is, with a very simple structure, it is possible to suitably realize a document storage file that can be classified into three documents.

なお、本実施形態においても、前述の第２の実施形態と同様の構成を備えてもよい。すなわち、表紙２におけるインデックス部２２、３０の対応位置に、筆記具（ボールペン等）による直接記入が可能な印刷が施されたメモ欄２８を設けてもよい（図７と同様に構成すればよい）。また、インデックス部２２、３０に、筆記具（ボールペン等）による直接記入が可能な印刷（表面処理）を施してもよい（図７と同様に構成すればよい）。 Note that this embodiment may also have the same configuration as that of the second embodiment described above. That is, a printed memo field 28 that can be directly written by a writing instrument (ballpoint pen or the like) may be provided at a position corresponding to the index portions 22 and 30 on the cover sheet 2 (the configuration may be the same as in FIG. 7). .. Further, the index portions 22 and 30 may be subjected to printing (surface treatment) that allows direct writing with a writing instrument (ballpoint pen or the like) (the configuration may be the same as in FIG. 7).

以上説明した通り、本発明によれば、きわめて簡素な構成により製造コスト、すなわち原材料コストおよび加工コストの増加を抑えつつ、複数の書類を仕訳して収納することが可能な書類収納ファイルを実現することができる。 As described above, according to the present invention, it is possible to realize a document storage file capable of sorting and storing a plurality of documents while suppressing an increase in manufacturing cost, that is, raw material cost and processing cost with an extremely simple configuration. be able to.

なお、本発明は、以上説明した実施例に限定されることなく、本発明を逸脱しない範囲において種々変更可能である。特に、収納対象として書類を例に挙げて説明したが、シート状の物品であれば書類と同様に収納することが可能である。 The present invention is not limited to the embodiments described above, and various modifications can be made without departing from the present invention. In particular, a document has been described as an example of a storage object, but a sheet-like article can be stored in the same manner as a document.
