Description

  The present invention relates to a book and a bookbinding method capable of opening pages between pages at a wide angle and allowing a printed matter such as continuous photographs to be substantially continuous at the throat.

A book is usually bound in a state where paper pieces are overlapped at a binding margin portion having a required width. For this reason, it becomes difficult to widen the throat part, and it becomes difficult to arrange continuous prints such as continuous photographs in a spread.
In order to make the spread wide and wide, for example, it is possible to attach the end face of the stack of paper pieces to a bendable back member with an adhesive and cover the outside with a flexible spine. (Registered Utility Model Publication No. 3104521: FIG. 6).
Registered Utility Model Publication No. 3104521

According to the technique disclosed in Japanese Patent Application Laid-Open No. H10-260260, the space between pages can be widened, so that a continuous photo or the like can be arranged almost continuously on a spread page.
However, there is a problem that the strength of the book is lowered because the end face of a group of paper pieces stacked in large numbers is merely adhered to the back member. That is, there is a conflicting problem that the strength must be sacrificed instead of widening as long as a binding margin of the required width is not provided.
Accordingly, the present invention has been made to solve the above-described problems, and an object of the present invention is to provide a book and a bookbinding method capable of widely opening between spread pages without sacrificing strength. .

In order to achieve the above object, the present invention comprises the following arrangement.
That is, the book according to the present invention is a book in which a plurality of paper pieces are bound, and the paper pieces are arranged in parallel with a print piece on which a printing unit such as a photograph is printed, and the print piece at a predetermined interval. A transparent resin sheet is adhered to the binding margin piece from both sides with the gap therebetween, whereby the printed piece covered with the resin sheet and the binding margin piece are connected by a connecting portion of the transparent resin sheet. A plurality of the paper pieces are overlapped and bound by the binding margin piece, covering the outside of the binding margin piece portion and the transparent resin sheet connecting portion portion, A spine having a letter shape is fixed to the binding margin piece.

Further, both end edge portions of the spine having a U-shaped cross section are bent support edges of the connecting portion of the paper piece.
Further, the spine is formed of cardboard having a strength sufficient to serve as the bent support edge.
Further, the present invention is characterized in that photographs are printed on the printing section, and both photographs on the facing paper piece are substantially continuous in the throat section.

Further, a front cover and a back cover are continuously provided at an end edge portion of the U-shaped spine cover through a bent portion.
The transparent resin sheet is a polypropylene resin sheet, and is thermally bonded to the printed piece and the binding margin piece.

  Further, the bookbinding method according to the present invention includes a step of forming a printed piece on which a printing portion is printed leaving a necessary margin on the binding margin side, and an elongated opening along the printing portion on the binding margin side of the printing piece. A step of forming a portion, a step of covering the front and back surfaces of the printed piece including the opening, and attaching a transparent resin sheet, and cutting the printed piece attached with the transparent resin sheet at a required location for printing. Forming a portion of a printed piece on which a portion is printed and a binding margin piece of a required width on a piece of paper connected by a connecting portion of a transparent resin sheet attached from both sides at the opening, and the formed A process of laminating a plurality of paper pieces, binding a plurality of paper pieces at the laminated binding piece portions, covering the outside of the bound binding piece portions and the connecting portion of the transparent resin sheet, Fixing a U-shaped spine to the binding margin piece. And wherein the door.

According to the present invention, since the paper piece is fixed at the portion of the binding margin piece having the required width, it is possible to bind firmly.
Further, since the printed piece of the paper piece is connected to the binding margin piece via the thin connecting piece, the paper piece bends at the thin connecting portion and opens largely outward. The other opposing paper piece is also greatly opened outward. That is, the connecting portion is thinner than the printed piece, and there is a gap between the connecting portions, and thus there is a space, so the paper piece can be bent with a small radius of curvature at the connecting portion, and without bending. Open outward. Therefore, the paper pieces opened outwardly are in a state where the bent portions are almost abutted. When the print portion of a photo or the like is printed up to the edge of the piece of paper, the photo of the spread page is continuous and the continuous photo is easy to see, such as a continuous photo of mountains.

DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is an explanatory view of a paper piece 10 to be bound into a book, and FIG. 2 is an explanatory view in which the paper piece 10 is closed to make a book.
The paper piece 10 is viewed from both sides with a gap A between a print piece 12 on which a printing unit 12a such as a photograph is printed, and a binding margin piece 14 arranged in parallel with the print piece 12 at a predetermined gap A. The transparent resin sheet 16 is stuck, and thereby the printed piece 12 covered with the resin sheet 16 and the binding margin piece 14 are formed on a piece of paper connected by the connecting portion 18 of the transparent resin sheet 16. The connecting portion 18 is a portion where the transparent resin sheets 16 on the front and back sides are adhered as they are at a portion in the interval A. The width | variety of the binding margin piece 14 is not specifically limited, What is necessary is just to be able to ensure a required intensity | strength when binding.

  Then, a plurality of the paper pieces 10 are stacked and bound at the binding margin piece 14. The means for binding the binding margin piece 14 is not particularly limited. Between the binding margin pieces 14 may be fixed with an adhesive, and various means such as fixing with a known fixed needle or using an adhesive and a fixed needle together may be used. Thus, since the paper piece 10 is fixed at the portion of the binding margin piece 14 having the required width, it is possible to bind firmly.

As described above, a plurality of sheets 10 bound by the spine cover 20 having a U-shaped cross-section, as shown in FIG. 2, are attached to the portion of the binding margin piece 14 and the portion of the connecting portion 18 of the transparent resin sheet 16. It is formed on the book 22 by fixing the spine cover 20 to the binding margin piece 14 so as to cover the outside.
Note that a front cover 20b and a back cover 20c are connected to the end edge portion of the spine cover 20 having a U-shaped cross section via a bent portion 20a, and are formed as an integral cover. The back cover 20, the bent portion 20a, the front cover 20b, and the back cover 20c are preferably formed integrally with relatively thick thick paper.

In the present embodiment, the front cover 20b and the back cover 20c can be replaced with the outermost sheet 10. In this case, the binding margin piece 14 and the connecting portion 18 may be covered only by the spine cover 20 having a U-shaped cross section.
It is preferable to use a polypropylene resin sheet for the transparent resin sheet 16, and it is preferable that the printed piece 12 and the binding margin piece 14 be thermocompression bonded.

Both edge portions (parts of the bent portion 20a) of the spine cover 20 having a U-shaped cross section serve as bent support edges at the connecting portion 18 of the paper piece 10.
Since the connecting portion 18 is formed by bonding the two transparent resin sheets 16, the connecting portion 18 is thin and easily bent.
Therefore, the paper piece 10 that is supported (becomes a fulcrum) at the edge of the spine cover 20 (part of the bent part 20a) and bent at the part of the thin connecting part 18 opens greatly outward. Similarly, the paper piece 10 on the other side is greatly opened to the other side.

In this case, as shown in FIG. 3, there may be a case where a plurality of the paper pieces 10 on the other side bend to the other side at the same time, but the connecting portions 18 are thinner than the printed pieces 12, and between the connecting portions 18. Since there is a gap and there is sufficient space in this way, the paper piece 10 on the other side can be bent with a small radius of curvature at the connecting portion 18 and opens largely outward in a state where the whole overlaps without bending. Therefore, the paper pieces 10 that are opened outwardly are in a state where the bent portions thereof are almost in contact with each other, and when the printing part such as a photo is printed up to the edge part of the paper piece 10, the photo of the spread page Will be continuous, and will be easy to view, such as mountains.
As described above, since both edge portions of the spine cover 20 are bent support edges of the paper piece 10, the spine cover 20 is preferably formed of thick paper having such strength.

Next, a bookbinding procedure (bookbinding method) will be described.
First, as shown in FIG. 4, a printing piece 12 is formed on which a printing portion 12a is printed leaving a necessary margin on the binding margin side, and the printing piece 12 is elongated along the printing portion 12a on the binding margin side. Opening 24 is formed.
Next, as shown in FIG. 5, the front and back surfaces of the printed piece 12 including the opening 24 are covered with the transparent resin sheet 16, and the transparent resin sheet 16 is adhered to the front and back surfaces of the printed piece 12 (FIG. 6).
As the transparent resin sheet 16, a polypropylene resin sheet is used, and it may be bonded to the front and back surfaces of the printed piece 12 by thermocompression bonding.
In the opening 24, the transparent resin sheets 16 are directly pasted together.

  Next, as shown in FIG. 7, the printed piece 12 to which the transparent resin sheet 16 is adhered is cut at the broken line portion B, and the portion of the printed piece 12 on which the printed portion 12 a is printed and the binding margin piece 14 having the required width, However, it forms in the paper piece 10 (FIG. 1) connected by the connection part 18 of the transparent resin sheet bonded by the opening part 24. FIG. Since the portions of the paper piece 10 on both sides of the opening 24 are also cut and removed, the printed piece 12 and the binding margin piece 14 are connected by only the connecting portion 18 to which the two transparent resin sheets 16 are bonded. Become.

  Next, as described above (FIG. 2), a plurality of the formed paper pieces 10 are stacked, and the plurality of paper pieces 10 are bound at the portion of the stacked binding margins 14 to form a U-shaped spine cover 20 having a U-shaped cross section. Thus, the spine cover 20 is fixed to the binding margin piece 14 so as to cover the outside of the binding margin piece 14 and the connecting portion 18 portion of the transparent resin sheet 16, thereby completing the bookbinding.
