In the jacket for books, at least one of the first sleeve 1A and the second sleeve 1B includes tongues 7A, 7B provided so as to extend in the vertical direction only in the region of the ground side, not in the region of the top side of the sleeves 1A, 1B. The tongues 7A, 7B make the ground side as a base end after the start of use and have movable parts 8A, 8B serving as a moving portion in the near side or far side of the surfaces of the sleeves 1A, 1B while extending toward the top side. The movable parts 8A, 8B have a length in the vertical direction longer than the distance between the base end and the edge of the ground side of the sleeves 1A, 1B.

Description

  The present invention relates to a book jacket and a book.

  Books sold at bookstores generally have a book jacket attached to the book body. The book body and the book jacket are separate members. In the book production process, after the book body is bound, the book jacket is attached to the book body to complete the book as a product. In such a book, the book jacket is only put on the book body, and is not necessarily in close contact with the book body. For this reason, while reading a book, the book body and the book jacket may be displaced from each other in the vertical direction, and the reader may be bothered.

  2. Description of the Related Art A book jacket in which a sleeve portion is provided with a detachment preventing portion is known as a device for preventing a deviation between a book body and a book jacket (for example, see Patent Document 1). Here, bend the tip of the stoppers provided at the top and bottom sides of the sleeves on both the front cover side and the back cover side in a total of four locations so that they wrap around the front cover side and the back cover side. This prevents the book jacket from coming off or slipping from the book body.

Japanese Utility Model Publication No. 2-150272

  However, in the above-described book jacket, since the detachment prevention portions are provided at the four places, it takes time for manufacturing and increases the cost. In particular, the detachment preventing portion provided on the top side is an obstacle to reading the information printed on the sleeve portion.

  Therefore, the present invention prevents a book body and a book jacket from being displaced in the vertical direction, reduces the manufacturing effort, and is low-cost and does not obstruct reading the information printed on the sleeve. The purpose is to provide a jacket. It is another object of the present invention to provide a book equipped with the book jacket.

  The book jacket of the present invention is a book jacket in which a first sleeve portion, a first main body portion, a back portion, a second main body portion, and a second sleeve portion are arranged in this order. At least one of the first sleeve portion and the second sleeve portion includes a tongue piece portion provided so as to extend in the top-and-bottom direction only in the ground-side region, not in the top-side region of the sleeve portion, The one part is fixed to the sleeve when not in use, and after the start of use, the movable part serving as a part moving from the ground side to the near side or the back side of the surface of the sleeve part is used as a ceiling. The movable part is configured such that the length in the top-to-bottom direction is longer than the distance between the base end and the edge on the ground side of the sleeve part.

  According to this book jacket, the length of the movable portion of the tongue piece portion in the vertical direction is longer than the distance between the proximal end of the movable portion and the ground side edge of the sleeve portion. When attached to the main body, the tongue piece portion can be bent so that the top end of the movable portion wraps around the front cover side and the back cover side of the book main body. This prevents the ground side edge of the front cover and back cover of the book body from protruding from the ground side edge of the book jacket to the ground side. That is, the vertical displacement between the book body and the book jacket can be prevented. In general, the contents of the book and the author's profile may be posted on the sleeve of the book jacket. At this time, the posted text often falls within the top side region of the sleeve, and the posted text does not necessarily reach the ground side region. For this reason, a tongue piece part does not become obstructive when reading the information printed on the sleeve part. In addition, the tongue piece portion only needs to be provided on at least one ground side of the first sleeve portion and the second sleeve portion, and is not provided on the top side, so that the labor of manufacturing is reduced and the cost is low. In addition, since the movable part is fixed to the sleeve part when not in use, it is possible to prevent the movable part from fluttering and causing unnecessary creases or tears.

  Here, the tongue piece portion has a first fold forming portion extending in a direction perpendicular to the top-and-bottom direction in the in-plane direction of the sleeve portion as a base end, and the tongue piece portion is the first fold forming portion. The second fold forming portion extending in parallel with the first fold forming portion is provided in the movable portion on the top side, and the tongue piece portion has the first fold forming portion and the second fold portion after the start of use. When the fold forming part is selected to fold or fold, the top end of the movable part goes over the edge on the ground side of the sleeve part and wraps around the surface on the opposite side of the sleeve part. It is preferable that the According to this, since both the first crease forming part and the second crease forming part extend in a direction perpendicular to the top-bottom direction, the fold forming part can be bent and moved by selecting a mountain fold or a valley fold. When the end of the top side of the part is passed over the ground side edge of the sleeve part and wraps around the surface on the opposite side of the sleeve part, the top side end part of the movable part can be accommodated with good appearance.

  The tongue piece includes a first crease formation guide provided on the first crease formation part along the first crease formation part, and a second crease formation part along the second crease formation part. A second crease formation guide provided on the top, and the distance between the first crease formation guide and the second crease formation guide is such that the first crease formation guide and the book jacket are books. It is preferable to be equal to the distance between the front side cover or the back cover side of the book main body when mounted on the main body. Since the crease formation guide has a structure for facilitating bending of the tongue piece, according to this, the mountain fold and the valley fold can be easily performed at appropriate positions. The distance between the first crease formation guide and the second crease formation guide, and the front cover or back of the book body when the first crease formation guide and the book jacket are attached to the book body. Since the distance between the cover side and the ground side is equal, the folding position of the second crease guide matches the position of the book side edge of the book jacket. According to this, since the protrusion of the movable part on the ground side of the book is minimized, the appearance of the book is good, and it is difficult to get in the way when the book is stood and stored on a bookshelf or the like.

  The tongue piece portion is composed of a part of the sleeve portion, and is defined as another region in the sleeve portion by at least one selected from the group consisting of a hole, a cut, a slit, and a perforation provided in the sleeve portion. It is preferable that it is formed. In this case, since other members for providing the tongue piece portion are unnecessary, it is easy to manufacture and resource saving.

  Here, at least one selected from the group consisting of a hole, a cut, a slit, and a perforation preferably extends continuously so as to surround the movable portion. According to this, the reader of the book equipped with the book jacket of the present invention can easily recognize that the tongue piece part and the movable part thereof are provided on the sleeve part of the book jacket.

  Moreover, it is also preferable that at least one selected from the group consisting of a hole, a cut, a slit, and a perforation extends continuously so as to surround the movable portion and has a discontinuous portion at least at one place. Having the discontinuous part allows the tongue piece to move when the tongue piece has not yet been creased (for example, when a customer picks up a book displayed at a bookstore). This prevents the part from flickering and causing unexpected creases or tears.

  Further, the tongue piece portion is made of a member having a fixing portion fixed to the sleeve portion, and the movable portion is provided continuously from the fixing portion via the proximal end and extends toward the top side, and when not in use. May be fixed to the sleeve portion, and may function as a portion that moves to the side where the tongue piece portion of the surface of the sleeve portion is fixed after the start of use. In this case, since the tongue piece portion is prepared as a member different from the sleeve portion regardless of the material of the sleeve portion, the degree of freedom in designing the strength of the movable portion is high.

  The present invention also provides a book in which the book jacket is attached to a book body.

  In this book, the crease may not be formed on the tongue piece. Further, in this book, the tongue piece portion is bent by selecting a mountain fold or a valley fold in any of the first fold forming portion and the second fold forming portion, and the top end portion of the movable portion Is sandwiched between the first body part or the second body part connected to the sleeve part and the front cover or back cover of the book body, and the front cover or back cover of the book body is movable. A state of being sandwiched between the top end portion of the head portion and the sleeve portion (hereinafter, not only the book jacket is simply attached to the book body in this way, but also the tongue piece portion is folded to A state in which the book jacket performs its function may be referred to as a “use state”).

  It is preferable that the book main body is ordinary bookbinding. In ordinary bookbinding, the cover is soft, and while reading a book, the cover is usually warped with the book jacket in the reader's hand. When the book jacket is in use, the movable portion of the tongue piece warps following the warpage of the cover. For this reason, it is prevented that the movable part is folded back during reading and the use state is released.

  According to the present invention, the book body and the book jacket can be prevented from shifting in the vertical direction, and can be manufactured at a low cost with reduced manufacturing effort, and it is difficult to read information printed on the sleeve. A book jacket can be provided. In addition, it is possible to provide a mounted book on which the book jacket is mounted.

[First Embodiment]
First, the book jacket will be described. As shown in FIG. 1, the book jacket 100 of the present embodiment has a first sleeve portion 1A, a first main body portion 2A, a back portion 3, and a second main body portion 2B, similarly to a normal book jacket. And the 2nd sleeve part 1B is connected and comprised in this order.

  Various information is printed on the surface of the book jacket 100 (Otemenen; the surface that appears as an external appearance when the book jacket is mounted). Here, as shown in FIG. 1 (a), the first sleeve portion 1A contains a book body content introduction sentence 4, the first body portion 2A and the back portion 3 contain a book title 5, and the second title portion 2A. The author's profile sentence 6 is printed on each sleeve 1B. Here, each piece of information is gathered and printed on the top side (upper side in the figure) of each part.

  On the other hand, information is not printed on the back surface of the book jacket 100 (the surface on the side facing the book body when it is mounted on the book body), as shown in FIG.

  In the present embodiment, as can be seen from the fact that the title of the book is printed on the first main body 2A, the book jacket attached to the main body of the book whose body is horizontally written (that is, the left-open book) is taken as an example. ing. Further, in FIG. 1, each boundary of the first sleeve portion 1A, the first main body portion 2A, the back portion 3, the second main body portion 2B, and the second sleeve portion 1B is indicated by a broken line. It is drawn for convenience of identification of each part in the specification, and the broken line is not actually printed on the book jacket 10.

Examples of the material of the book jacket 100 include paper or resin. As the paper, it is preferable to use, for example, coated paper, especially coated paper. The thickness of the paper is preferably 100 kg to 200 kg, more preferably 110 kg to 180 kg in terms of the continuous weight, from the viewpoint of ensuring the strength of the tongue pieces 7A and 7B described later. More specifically, 110 kg, 135 kg, and 180 kg are mentioned. The thickness of the paper is preferably from 100g ^{/ m 2} ~210g ^/ m 2 as a meters basis ^{weight, 120g / m 2 ~200g / m} 2 is more preferable.

  Tongue pieces 7A and 7B are provided in the same area as the sleeves 1A and 1B in the ground side regions of the first sleeve 1A and the second sleeve 1B, respectively. The tongue pieces 7A, 7B are respectively formed from a part of the sleeves 1A, 1B, and in the positions separated from the edges of the sleeves 1A, 1B, a U-shaped notch with the open part facing the ground side is the sleeve part. By being provided in 1A and 1B, it is formed by being demarcated from other regions in the sleeve portions 1A and 1B. As shown in FIGS. 2 (a) to 2 (c), the tongue pieces 7 </ b> A and 7 </ b> B have a portion that passes between both ends of the U-shaped cut as a base end by the U-shaped cut. , 1B, movable parts 8A, 8B that can move toward the front side or the back side are extended toward the top side. In other words, the incisions formed by separating the tongue pieces 7A and 7B from other areas of the sleeve portions 1A and 1B continuously extend so as to surround the movable portions 8A and 8B. In addition, when moving movable part 8A, 8B is moved, the trace space where movable part 8A, 8B before moving existed becomes window W. In addition, although the code | symbol of "8B", "9B", and "10B" does not appear in drawing, these codes | symbols are in the tongue piece part 7B (refer FIG. 1) provided in the 2nd sleeve part 1B. Assume that the same structure (“8A”, “9A”, “10A”) in the tongue piece 7A provided on the first sleeve 1A is indicated.

  The tongue pieces 7A and 7B have first crease forming portions 9A and 9B extending in a direction perpendicular to the top-and-bottom direction among the in-plane directions of the sleeve portions 1A and 1B, respectively, as the base ends. Then, the tongue pieces 7A and 7B are formed in the second fold forming portion extending in parallel with the first fold forming portions 9A and 9B in the movable portions 8A and 8B on the top side with respect to the first fold forming portions 9A and 9B. Each has parts 10A and 10B. In FIG. 2, the first crease forming portions 9A and 9B and the second crease forming portions 10A and 10B are indicated by broken lines, but these are drawn for convenience of identification in this specification. Actually, the broken line is not printed on the part.

  Here, the movable portions 8A and 8B have a length in the top-and-bottom direction, the base end (this is also a portion formed as the first fold forming portions 9A and 9B) and the ground side of the sleeve portions 1A and 1B. Longer than the distance between the edges. The distance between the first crease forming portions 9A and 9B and the second crease forming portions 10A and 10B (hereinafter also referred to as “distance A”) is the same as that for the first crease forming portions 9A and 9B and the book. It is set to be equal to the distance (hereinafter also referred to as “distance B”) between the front side cover of the book body and the ground side of the book body when the jacket 100 is attached to the book body. Since these length relationships are established around the tongue pieces 7A and 7B, as shown in FIG. 2 (d), the first fold forming portions 9A and 9B and the second fold forming portions 10A, 10B, when folded by valley folds, the top end of the movable part 8A, 8B goes over the edge of the sleeve 1A, 1B on the ground side and wraps around the opposite side of the sleeve 1A, 1B It is possible to make it. Here, “valley fold” refers to folding the book jacket 100 in the direction of valley fold when viewed from the surface.

  Here, the length of the distance A and the distance B is preferably 5 mm to 15 mm, more preferably 6 mm to 14 mm, still more preferably 7 mm to 13 mm, and particularly preferably 8 mm to 12 mm. The vertical length of the movable parts 8A and 8B is preferably 25 mm to 45 mm, more preferably 27 mm to 43 mm, still more preferably 28 mm to 41 mm, and particularly preferably 29 mm to 38 mm. The width in the direction perpendicular to the vertical direction of the movable parts 8A and 8B is preferably 10 mm to 40 mm, more preferably 12 mm to 35 mm, still more preferably 13 mm to 30 mm, and particularly preferably 15 mm to 25 mm. Any of the above numerical values is appropriately selected according to the ease of handling, appearance, strength, and the like of the movable parts 8A and 8B.

  The position where the movable portions 8A and 8B are provided in the sleeve portions 1A and 1B is movable when it is assumed that the sleeve portions 1A and 1B are provided with a scale that divides the width in the direction perpendicular to the vertical direction into 100 equal parts. The position of the center line in the vertical direction of the portions 8A and 8B is preferably located at a position of 20 to 80 on the scale, and more preferably located at a position of 30 to 70. This position is selected from the viewpoint of the balance that supports the book body in the usage state of the book jacket 100.

  A tongue piece portion is not provided in the top region of the first sleeve portion 1A and the second sleeve portion 1B.

  Next, a method for using the book jacket 100 will be described.

  As shown in FIG. 3A, in general, a book 300 displayed and sold at a bookstore has a book jacket 100 detachably attached to a book body 200. In the book 300, the boundary between the sleeve portions 1A, 1B and the main body portions 2A, 2B is bent, and the sleeve portions 1A, 1B are back side of the front cover 201 of the book main body 200 and the back side of the back cover 202 (book main body 200). ). Here, it is assumed that the book body 200 is an ordinary bookbinding.

  The reader of the book 300 lifts the movable part 8A of the tongue piece part 7A as shown in FIG. 2B, and then bends it by valley folding at the first crease forming part 9A. Then, the second crease forming part 10A is also bent. In this process, as shown in FIG. 3B, when the tongue piece portion 7A is bent to the limit by the first fold forming portion 9A, the first fold forming portion 9A and the second fold forming portion 9A of the movable portion 8A. The region between the crease forming part 10A faces the region between the first crease forming part 9A and the ground side edge of the first sleeve 1A. Then, the second fold formation is performed while the end portion of the movable portion 8A on the front end side of the second fold forming portion 10A is inserted between the first main body portion 2A and the front cover 201 of the book main body 200. Fold it to the limit with the valley fold at the part 10A. As a result, as shown in FIGS. 3C and 3D, the end portion that was the top end of the movable portion 8 </ b> A before being bent is the front cover 201 of the first main body portion 2 </ b> A and the book main body 200. And the cover 201 of the book body 200 is sandwiched between the end of the movable portion 8A and the first sleeve 1A.

  Then, the same bending operation as described above is also performed on the tongue piece 7B on the second sleeve 1B side. With these operations, the book jacket 100 is put into use.

  According to the book jacket 100 described above, the lengths of the movable portions 8A and 8B of the tongue pieces 7A and 7B in the vertical direction are the base ends of the tongue pieces 7A and 7B and the ground sides of the sleeve portions 1A and 1B. When the book jacket 100 is attached to the book main body 200, the top ends of the movable portions 8A and 8B are the front cover 201 side and the back cover 202 of the book main body 200 when the book jacket 100 is attached to the book main body 200. The tongue pieces 7A and 7B can be bent so as to go around. This prevents the ground side edges of the front cover 201 and back cover 202 of the book body 200 from protruding from the ground side edge of the book jacket 100 to the ground side. That is, the vertical displacement between the book body 200 and the book jacket 100 can be prevented.

  More specifically, the book body 200 is usually heavier than the book jacket 100, and the force applied to the book 300 with the fingertips when the book 300 is picked up and held during the reading, during reading. The book body 200 is relatively downward and the book jacket 100 is relatively upwardly moved and displaced from each other, which makes the reader bothersome. On the other hand, according to the book jacket 100 of the present embodiment, the ground side edges of the front cover 201 and the back cover 202 of the book main body 200 come into contact with the bent tongue pieces 7A and 7B. Since the pieces 7A and 7B can support the weight of the book body 200, it can function as a stopper for this relative displacement, and the occurrence of the displacement can be prevented.

  In the book jacket 100 of the present embodiment, since the tongue piece portion is not provided on the top side, the opposite displacement, that is, the book body 200 is relatively upward, and the book jacket 100 is relatively downward. It is not possible to prevent them from shifting to each other. Nonetheless, the above-described relationship between the weight of the book body 200 and the book jacket 100 and the amount of fingertip force in the reader's hand does not normally cause such a shift, thus eliminating the reader's annoyance. For this, the aspect of the present embodiment in which the tongue pieces 7A and 7B are provided only on the ground side is sufficient.

  Here, in the book jacket disclosed in Patent Document 1, a slip-off preventing portion (corresponding to a tongue piece) is provided not only in the ground-side region of the sleeve portion but also in the top-side region. This is considered to be considered not to cause not only “shift” in the vertical direction of the book jacket but also overall “displacement”. In Patent Document 1, only “moving up and down” is described as “shift” in the vertical direction. On the other hand, the book jacket 100 according to the present embodiment does not capture the “displacement” simply as “moving up and down”, but is asymmetric to the displacement in the vertical direction due to the action of gravity or the force of the fingertip. In particular, the book main body 200 is relatively downward and the book jacket 100 is relatively easy to move upward, and this has been prevented. .

  In addition, in the sleeve portions 1A and 1B, the content introduction sentence 4 and the author's profile sentence 6 of the book 300 are printed in close contact with the top area of the sleeve portions 1A and 1B. The tongue pieces 7A and 7B are unlikely to get in the way of reading the printed information. Further, since it is not necessary to provide the tongue pieces 7A and 7B on the top side of the sleeve portions 1A and 1B, the manufacturing effort is reduced and the cost is low. In addition, since it is not necessary to operate the top side, there is little effort when the book jacket 100 is put into use.

  Further, the tongue pieces 7A and 7B extend in the direction perpendicular to the top-and-bottom direction among the in-plane directions of the sleeve portions 1A and 1B, and are parallel to each other, the first fold forming portions 9A and 9B and the second fold forming portion 10A. , 10B, so that the end of the movable part 8A, 8B can be moved with a good external shape when the edge of the sleeve part 1A, 1B is passed over the edge of the sleeve 1A, 1B and the other side is wrapped around. The ends of the portions 8A and 8B can be accommodated.

  The distance between the first crease forming portions 9A and 9B and the second crease forming portions 10A and 10B is such that the first crease forming portions 9A and 9B and the book jacket 100 are attached to the book body 200. Since the distance between the front cover 201 or the back cover 202 of the book main body 200 is equal to the distance between the side of the book body 200 and the ground side, the folding positions at the second fold forming portions 10A and 10B are the sleeve portions 1A and 1B. It corresponds to the position of the edge of the ground side. According to this, since the protrusion of the movable parts 8A and 8B on the ground side of the book 300 is minimized, the appearance of the book is good, and it is difficult to disturb the book 300 when stood on a bookshelf or the like.

  The tongue pieces 7A and 7B are formed of a part of the sleeve portions 1A and 1B, and are formed to be separated from other regions in the sleeve portions 1A and 1B by notches provided in the sleeve portions 1A and 1B. Therefore, since other members for providing the tongue pieces 7A and 7B are unnecessary, it is easy to manufacture and saves resources. Here, since the incision continuously extends so as to surround the movable portions 8A and 8B, the reader of the book 300 with the book jacket 100 attached thereto has the tongue piece portions 7A and 7B and the movable portion 8A. , 8B can be easily recognized as being provided on the sleeve portions 1A, 1B of the book jacket 100.

  Moreover, the cover of the average bookbinding as the book body 200 is soft. For this reason, when inserting the end portions of the movable portions 8A and 8B between the first main body portion 2A and the front cover 201, the first main body portion 2A and the front cover 201 The space between can be opened widely. Therefore, the insertion operation can be easily performed as compared with the case where the book body is an upper bookbinding.

  Further, in the case of reading a book 300, the ordinary bookbinding is usually in a state where the covers 201 and 202 are warped together with the book jacket 100 in the reader's hand. When the book jacket 100 is in use, the movable portions 8A and 8B of the tongue pieces 7A and 7B warp following the warpage of the cover sheets 201 and 202. For this reason, it is prevented that movable part 8A, 8B is folded back during reading and a use condition is cancelled | released.

  Next, a modification of this embodiment will be introduced.

  In the above-described embodiment, the tongue pieces 7A and 7B are shown to be formed so as to be separated from other regions in the sleeve portions 1A and 1B by providing cuts in the sleeve portions 1A and 1B. As shown, the cuts are perforated (Fig. 4 (a)), slits (Fig. 4 (b)), continuous holes (Fig. 4 (c)), or a combination of cuts and perforations. (FIG. 4D) or the like may be used. Here, the “slit” refers to a punched gap having a width unlike a notch. In addition, in FIG. 4 and FIGS. 5-7 demonstrated below, it should be noted that in order to avoid complexity, some reference numerals are not attached.

Moreover, in the said embodiment, although the cut | notch showed the aspect extended continuously so that movable part 8A, 8B might be surrounded, it has a discontinuous part in at least one place of continuous extension. It may be. For example, as shown in FIG. 5, the apex portion on the top side may have a discontinuous portion (FIGS. 5A, 5 </ b> B, and 5 </ b> C) and discontinuous in other portions. It may have a portion (FIG. 5D). In these cases, when the crease portions 7A and 7B are not yet creased (for example, when a customer picks up a book displayed in a bookstore), the movable portions 8A and 8B flutter and move unexpectedly. It is possible to prevent unnecessary creases and tears from being generated.
5 (a), (b), (c) and (d), the tongue portions 7A and 7B are movable portions 8A when not in use (a state where they have never been used). , 8B is fixed to the sleeves 1A, 1B by the discontinuous parts, so it does not work as a part that moves to the front side or the back side of the surface of the sleeves 1A, 1B. , And after the first use), the discontinuous part is cut off to become a continuous point, and the movable parts 8A, 8B act as parts that move toward the front side or the back side of the surface of the sleeve parts 1A, 1B. Become. The usage method and effects of the book jacket after the start of use are the same as in the above embodiment.

  Further, as shown in FIG. 6, in the first sleeve portion 1A of the above embodiment, the first crease formation guide 19A is provided on the first crease formation portion 9A, and the second crease formation guide 19A is provided on the second crease formation portion 9A. The second crease formation guide 20A may be provided on the crease formation portion 10A. For example, the first crease formation guide 19A and the second crease formation guide 20A may be provided with thin portions by linear embossing (FIG. 6 (a)), lines (here broken lines) and characters (here) The characters “valley fold” may be printed (FIG. 6B), holes may be provided (FIG. 6C), or a combination thereof may be provided (FIG. 6D). . The first crease formation guide 19A and the second crease formation guide 20A make it easy to bend the tongue piece portion 7A by structurally indicating the presence of the first crease formation portion 9A and the second crease formation portion 10A. Therefore, according to these, the mountain fold or the valley fold can be easily performed at an appropriate position in the first fold forming portion 9A and the second fold forming portion 10A. At this time, similarly, also in the second sleeve portion 1B, the first crease formation guide is provided on the second crease formation portion 9B, and the second crease formation portion 10B is provided. Then, a second crease formation guide is provided thereon.

  Further, in the above-described embodiment, an aspect in which the incision is a U-shape, that is, an aspect in which the movable parts 8A and 8B are rectangular has been shown. The shape may be different. For example, as shown in FIG. 7, it may have a shape like a bottle (FIG. 7A), a shape like a rock (FIG. 7B), or a shape like a human (FIG. 7). (C)), a cat-like shape may be used (FIG. 7 (d)). In these cases, it is expected to be visually enjoyable and motivated to purchase a book equipped with the book jacket. Moreover, if a movable part or tongue piece part having these shapes is drawn or colored, it becomes more visually pleasing.

  As a modification of the method of use, there is a mode in which the folds in the first crease forming portions 9A and 9B are mountain-folded instead of valley-folded. In this case, as shown in FIG. 8, the ends of the movable portions 8A and 8B do not climb over the ground side edges of the sleeve portions 1A and 1B, but the movable portions 8A and 8B are folded so that the book body Receiving ports for 200 cover sheets 201 and 202 are formed. In the use state, the covers 201 and 202 of the book body 200 are sandwiched between the folded movable portions 8A and 8B. In FIG. 8, the first main body 2A of the book jacket 100 is omitted.

  As a modification of the method of use, the tongue pieces 7A and 7B may be folded in advance before the book jacket 100 is attached to the book body 200. In the above embodiment, even though the book body 200 is a standard bookbinding, it may take time to insert the end portions of the movable portions 8A and 8B between the main body portions 2A and 2B and the cover sheets 201 and 202. Therefore, the cover pieces 201 and 202 of the book body 200 are inserted between the end portions of the movable portions 8A and 8B and the sleeve portions 1A and 1B by previously bending the tongue pieces 7A and 7B. Thus, the book jacket 100 can be easily attached to the book body 200 and put into use.
