Description

[Detailed Description of the Invention] Industrial Application Field The present application compares a binding portion of a back cover having a binding piece integrally with a binding portion of a cover sheet provided with binding holes with a sheath body for comparison. Files related to binding thin documents.

2. Description of the Related Art Conventionally, a back cover and a front cover are integrally connected to each other via a fold line, and a pair of cleavable binding pieces are provided near the fold line position of the back cover, and the front cover is A pair of binding holes through which the binding piece is inserted are formed near the folding line position, and after binding the required document, insert the binding piece into the binding hole of the cover that is closed by the folding line, and display it. A file formed by bending on the surface of the cover and pressing a binding portion including the binding piece in this state with a sheath body is known, for example, from Japanese Utility Model Laid-Open No. 56-151186.

However, according to the conventional file described above, since the front cover and the back cover are integrally connected, the front cover and the back cover are limited to a single material, Therefore, for example, in order to make it easier to open a bound document, for example, when it is made of a flexible synthetic resin plate, the back cover becomes weak and inconvenient to use, and in order to make the back cover strong. When it is made of a relatively thick synthetic resin plate or thick paper, it is inconvenient to spread the document and the cost is increased. Further, in a binding device for documents and the like, when the binding piece inserted in the binding hole of the document is further inserted in the binding hole of the front cover, the front cover and the back cover are continuous, and the binding piece and the binding are Since it is close to the hole, it has a defect that it is difficult to insert the binding piece into the binding hole, and since the sheath body is simply engaged with the binding part, the sheath body moves vertically during use. There was a fear that it would be inconvenient to handle.

Means for Solving the Problems Therefore, in order to achieve the above-mentioned object, the present application integrally provides a binding portion provided on one side with a plurality of binding pieces that are long in the vertical direction, and at least the binding portion. A back cover having a foldable locking tongue extending on the back surface of the binding section at one of the outer edges of the upper and lower ends, and a plurality of sheets for inserting the binding pieces into the binding section provided on one side, respectively. A front cover having a binding hole, a front piece and a back piece, and a back portion that closes the outer edges of the front and back pieces, and the locking tongue piece is provided on the inner side of either one of the upper and lower ends of the back piece. A cutout portion that engages with a part of the front piece and the inner edge of the back piece and the front cover, and a sheath body that presses the binding portion of the back cover. In order to facilitate the engagement of the sheath body in the above, the lower edge of the locking tongue to the upper edge of the lower end locking tongue are locked from the horizontal portion and the end thereof. It is formed by an inclined portion that extends obliquely to the bending position of the tongue piece.

Function When using, however, with the back cover, the front cover and the sheath body disassembled, the locking tongue of the back cover is folded back to the back side of the binding part, and the binding piece that stands up on the front cover surface is used. After inserting the binding hole of the document into the sheet, insert the binding hole of the front cover, insert the document between the back cover and the front cover, and in this state, at the binding end, While pushing open, the binding portion of the back cover and the binding portion of the front cover are slidably inserted between the front piece and the back piece, and in this case, the binding piece is previously covered. By folding the surface of the sheet, the binding piece easily intervenes between the front and back pieces. In this state, the overlapped part where the back cover, the document and the front cover are stitched together is strongly pinched by the inner edges of the front and back pieces. The edge engages with the side edge of the binding piece, and the retaining in the vertical direction is performed by the engagement tongue engaging with the notch.
