DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in order from the first embodiment with reference to the accompanying drawings. 1 and 2 are explanatory views of a book to which the first embodiment is applied, (A) is a perspective view of the book in which the first and second cover pieces are closed, and (B) is the first cover piece. The open book perspective view, (C) shows the perspective view of the book which opened the 1st and 2nd cover piece. Reference numeral 1 is a book, and in the embodiment, the book 1 is a monthly or weekly magazine, and the book 1 is composed of a booklet section 2 and a cover 3. The cover sheet 3 is composed of a cover sheet 4 arranged on one surface side of the booklet section 2 and a back cover sheet 5 arranged on the other surface side of the booklet section 2, and constitutes the cover sheet 4 and the back cover sheet 5. One sheet of paper is bound on the spine 6 of the booklet section 2 by a perfect binding method or a saddle stitching method. In the drawings, an upward convex curved arrow indicates a valley fold, and a downward convex curved arrow indicates a mountain fold.

The front cover sheet 4 has a first cover sheet 7 connected to the back cover sheet 5 on the spine 6 side and a second cover sheet 2 folded back from the first cover sheet 7 via the first fold line 8 on the edge side of the booklet section 2. It is composed of a cover sheet 9. The first cover sheet 7 is the first
The fold line 8 is formed with a width smaller than that of the booklet portion 2 so as not to be cut. The second cover sheet 9 has a width almost equal to that of the first cover sheet 7 or is larger than that of the first cover sheet 7 so that the second cover sheet 9 can be smoothly folded and does not project outside the booklet portion 2 when folded back. Is also formed with a slightly smaller width. In this embodiment, the top and bottom of the first and second cover sheets 7 and 9 are formed in a size that matches the top and bottom of the booklet 2.

The second cover sheet 9 is, for example, as shown in FIG. 1C, valley-folded from the first folding line 8 to form the first cover sheet 7.
1A, and in this state, the first cover sheet 7 is folded from the spine 6 side onto the sheet piece 201 located at the uppermost position of the booklet portion 2 as shown in FIG. 1B. Therefore, the outer surface of the first cover sheet 7 becomes the outermost cover of the book 1. 2C, the second cover sheet 9 is mountain-folded from the first folding line 8 and folded on the outer surface of the first cover sheet 7, as shown in FIG.
As shown in (B), the first cover sheet 7 is placed from the spine 6 side to the booklet portion 2
2 is folded on a piece of paper 201 located on the uppermost side of FIG.
The state of (A) is established, so that the inner surface of the second cover sheet 9 becomes the outermost cover sheet of the book 1. In the book 1 having the cover having such a configuration, the second cover piece 9 is folded from the first fold line 8 into a mountain fold or a valley fold to be folded into the first cover piece 7, and then the first and second cover pieces. 7 and 9 are folded on the paper piece 201 of the booklet section 2 and then cut on three sides, and at the time of three-side cutting, the top and bottom of the back cover 5 and the first and second cover pieces 7 and 9 are placed on the booklet section 2. It is cut along with the top and bottom of.

According to the present embodiment, the cover sheet is composed of two sheet pieces, that is, the first cover sheet piece 7 and the second cover sheet piece 9 having a width slightly smaller than the width of the booklet portion 2. Compared with a cover consisting of a single piece of paper having the same width as the booklet section 2, it is possible to increase the practical value of the cover and add fun to the cover, thus increasing the purchasing power of consumers. It is possible to increase the sales volume of the book. Further, when the first cover sheet 7 and the second cover sheet 9 are opened, the width obtained by adding the width of the first cover sheet 7 and the width of the second cover sheet 9 to the first and 2 The outer surface or the inner surface of the cover sheets 7 and 9 can be configured as one surface. Similarly, in the width of the paper piece 201 of the booklet section 2, the first and second cover pieces 7,
The width obtained by adding the width of the inner surface of 9 or the width of the outer surface of the back cover sheet 5 to the width of the outer surface of the first and second cover sheets 7 and 9 is 1
It can be configured as one surface. The function of this surface, particularly the function of the inner surface of the first and second cover sheets 7 and 9 has been conventionally performed by arranging a folded page on the next page of the cover sheet, but in the present embodiment, the function of the cover sheet is the most important. A large surface can be formed in the conspicuous part, and the cover is opened at the very beginning, so that the use value and practical value of the cover itself are significantly increased. Further, the inner surfaces of the first and second cover sheets 7 and 9 can be used, for example, for special pages, gravure photo pages, table of contents pages, announcement pages, etc. By increasing the space, the size of characters, the layout of photographs, etc. The greater the degree of freedom, the easier it is for users to read by making it easier to open, and it is possible to attract more attention from consumers than conventional folding pages, motivate consumers to buy and increase the sales volume of books. can do.
