  An embodiment of the book cover of the present invention will be described.

  FIG. 1 shows a book cover according to the first embodiment of the present invention, and FIG. 2 shows a book to which the book cover is attached. The book cover 10 of the present invention includes a book cover main body 16 and a light emitting member 17. First, the book cover body 16 has a back part 11 located on the back 21 of the book 20, a front cover part 12 and a back cover part 13 respectively located on the front cover 22 and back cover 23 of the book, and the front and back cover parts 14. Each of the folds 15 is connected to each other. The book cover 10 is attached to the book 20 by folding each folding part 15 into the back side of the front / back cover 24 of the book 20.

  On the other hand, the light emitting member 17 is provided on the back portion 11 of the book cover main body 16. The light emitting member 17 includes a light emitting element 18 provided on the base material 19, a power source (not shown), and a switch (not shown). A drive circuit and / or an electromagnetic wave sensor is provided on the base material 19 as necessary. Provided on top. By providing the light emitting member 17 on the back portion 11, light is emitted from the back portion 11 toward the outer front side of the back portion. By attaching the book cover of the present invention to the target book, this light emission becomes a mark, and the target book can be easily found in various storage and installation states of the book.

  In all the embodiments of the book cover of the present invention, the light emitting member may be provided on both the back portion and the cover portion. In this case, even when the book is placed with the cover facing up, the book can be easily found by using the light emitted from the cover as a mark. The structure of the light emitting member will be described in detail separately.

  The book cover body is formed of a material such as paper, cloth, or flexible resin, and any material that is transparent or opaque can be used.

  As shown in FIG. 1, the structure of the folded portion is simply folded into the back side of the cover 24, and the top and bottom edges of the folded portion and the top and bottom edges of the folded portion are joined to form a bag portion. A structure may be adopted in which a book cover is inserted into the bag portion and fixed.

  In the present embodiment, the book cover main body 16 and the light emitting member 17 are integrally formed. That is, the light emitting member 17 is formed directly on the book cover main body 16 or formed on another resin base material, and then adhered to the book cover main body 16. Thus, by integrally forming the book cover main body and the light emitting member, the light emitting member can be easily handled without falling off. For this reason, the operation | work attached to a book can be performed efficiently.

  In addition, when attaching the book cover of this invention to the book with this accessory cover, as shown in FIG. 3, this book cover 30 is attached to the outer side of the book 20, and also the book cover 10 of this invention is provided on the outer side. Is installed. The book cover shown in FIG. 1 wraps around the entire back and cover of the book. However, as shown in FIG. 4, a part of the back and cover of the book may be wrapped by forming a belt-like book cover 40.

  The book to which the book cover of the present invention is attached can be arbitrarily set by a person who handles the book. For example, if it is a bookstore, the best-selling books, articles introduced in newspaper articles, if it is a library, school recommended books, new collections, etc., if it is an individual, frequently read books, commemorative books, etc. The book cover of the present invention can be set as an attachment target.

  Here, when a transparent material is used for the book cover body, the light emitting member is provided at a position close to the upper end of the back portion as shown in FIG. It is preferable to form an area that does not hide. If the book cover has such a configuration, the book-specific information printed on the back or cover of the book can be read through the transparent book cover body. This is because it is possible to prevent a situation in which it is difficult to identify a book or to hide the aesthetics or intellectual impression given by the book-specific information. For this reason, the book cover having such a configuration is particularly preferably used when books are stored in a library or a bookstore.

  Further, in all embodiments of the book cover of the present invention, the planar shape of light emitted from the light emitting element is reminiscent of the pattern irrelevant to the book specific information of the book to which the book cover is attached, or the purpose of attaching the book cover. A pattern is preferred. The pattern can be displayed by forming the light emitting element itself in a shape corresponding to the pattern. Or it can display by taking out light emission from the light emitting element in the shape according to the said pattern. Examples of a method for extracting light emission in a shape corresponding to the pattern include a method of disposing a sheet having a light transmission pattern corresponding to the pattern on the upper surface of the light emitting element. Patterns that are not related to this specific information include geometric patterns such as rectangles, circles, polygons, and spot shapes, simple numbers, letters, symbols, or combinations thereof that do not have any special meaning in themselves. It is said. The book cover of the present invention can be used universally for any book as long as it is a pattern unrelated to the book unique information. FIG. 1 shows a square light emission shape. On the other hand, as a pattern reminiscent of the purpose of attaching the book cover, it can be arbitrarily set by the person who handles the book, but it may be a number, a letter, a symbol, or a combination of these, or a book recommended by a bookstore. It may be a phrase or a sentence such as “Recommended” for a birthday or “Happy birthday” for a book to be given on a birthday. As described above, if the pattern is reminiscent of the purpose of attaching the book cover, the purpose can be known only by looking at the light emission.

  The inventions of the second embodiment and the third embodiment are characterized by comprising means for attaching / detaching the light emitting member to / from the book cover main body. Since the light emitting member can be attached to and detached from the book cover body, the light emitting member can be attached and detached as necessary. For example, when reading a novel or referring to an academic book to write a paper, the book is read frequently over a certain period of time, and it is almost impossible to read after a certain period. In such a case, by attaching the light emitting member only for a period of high frequency of reading, even if the book that has been read is once returned to the bookshelf, the target book can be easily found when reading next time. is there. For this reason, the book cover of the embodiment provides convenience for the reader of the book.

  First, the book cover of the second embodiment will be described. The second embodiment is a book cover provided with means for attaching and detaching a light emitting member to the front side of the book cover main body.

  A first example of the second embodiment is shown in FIG. In FIG. 5, slits 50 are provided in the surface of the cover portion 14 of the book cover main body 16 and in the vicinity of both sides of the back portion 11. Insertion portions 51 that engage with the slits 50 are formed at both left and right ends of the light emitting member 17. The light emitting member 17 is attached to the book cover main body 16 by inserting the insertion portion 51 into the slit 50. Here, in the overlap part of the cover part 14 and the light emitting member 17, the insertion part 51 protrudes in the back side of the cover part 14, and it is only necessary to become thick only for the base material thickness of the light emitting member. For this reason, when putting a book in and out of the narrow gap of a bookshelf, the operation | movement which puts in / out is prevented or a light emitting member does not remove | deviate. In addition, since only the shapes of the book cover main body and the light emitting member are processed, the attaching / detaching means can be provided easily and inexpensively.

  A second example of the second embodiment is shown in FIG. In FIG. 6, a hook-and-loop fastener 60 is provided around the light emitting member 17, and a hook-and-loop fastener 60 is provided on the back portion 11 of the book cover main body 16 so as to engage with the hook-and-loop fastener 60. This makes it possible to attach and detach the light emitting member from the outside of the book cover main body. As a means for attaching and detaching the light emitting member, a hook can be used in addition to the slit and the hook-and-loop fastener.

  Next, a third embodiment will be described. The book cover of the third embodiment is a book cover provided with means for attaching and detaching the light emitting member to the back side of the book cover main body.

  FIG. 7 is a diagram illustrating a first example of the third embodiment. In FIG. 7, a bag portion 70 is formed in a predetermined region on the back side of the book cover main body 16 and extending from the back portion 11 to the front and back cover portion 14. The top end of the bag portion 70 is an opening 71. The width W1 of the opening is formed to be smaller than the width W2 of the bag portion and the light emitting member. The light emitting member 17 has a shape corresponding to the shape of the bag portion 70. As a base material of the light emitting member 17, a flexible resin sheet is used. The light emitting member 17 is attached to the bag portion 70 by being inserted into the opening 71 in a direction in which light is emitted outward from the back portion 11. At this time, the area of the book cover main body corresponding to the position of the light emitting element is a light transmissive area 72 so that light emitted from the light emitting member 17 can be observed from the outside. The light-transmitting region 72 is formed so as to transmit all or part of the emitted light by an opening, a transparent film, a translucent film, Japanese paper, a colored film, matte paper, or the like. In FIG. 7, the light emitting member can be attached to the book cover main body by a simple operation of inserting the book cover into the bag while the book cover is still attached to the book. Also, when the book cover is attached to the book, the light emitting member is bent and fixed along the back of the book and the opening width of the bag is narrower than the width of the light emitting member, so hold the book upside down. However, there is no risk of the light emitting member dropping off.

  FIG. 8 is a diagram illustrating a second example of the third embodiment. In FIG. 8, a bag portion 70 is formed continuously on one side of the top side of the book cover main body 16. The light emitting member 17 having a shape corresponding to the shape of the bag portion is inserted into the bag portion 70 from the direction of the arrow A. Thereafter, the bag portion 70 is folded back to the back side of the book cover main body 16 along the fold line 83 in the direction of arrow B, whereby the mounting of the light emitting member 17 to the book cover main body 16 is completed. In the state where the mounting of the light emitting member is completed, the area of the book cover main body corresponding to the position of the light emitting element is a light transmissive area 72, so that the light emitted from the light emitting member can be observed from the outside. Yes. Here, notches 81 and 82 are provided at one corner of each of the light emitting member and the bag portion. As a result, the light emitting member 17 can be inserted into the bag portion 70 in the correct orientation. At the stage where the mounting of the light emitting member is completed, the light emitting member is in a state where the upper part is blocked over its entire width. For this reason, when the book is held upside down, the light emitting member can be reliably prevented from falling off.

  FIG. 9 is a diagram illustrating a third example of the third embodiment. 9A, the back portion 11 of the book cover main body 16 is formed by overlapping two book cover materials. The width of these two materials is longer on the outside than on the inside. As a result, the light emitting member mounting gap 90 is secured in the back portion 11, and the light emitting member shown in FIG. 9B is mounted in the light emitting member mounting gap 90. FIG. 9C shows a DD cross section of the light emitting member 17. As shown in FIG. 9C, the light emitting member 17 leaves the region where the light emitting element 18, the power source, the switch and other components are provided, and the cushioning sheet 94 surrounds the periphery of the base material 19. It is fixed. The light emitting member 17 is inserted into the light emitting member mounting gap 90 while the cushioning sheet 94 is compressed. At this time, the light emitting member 17 is fixed to the light emitting member mounting gap 90 by utilizing the repulsive force of the cushioning sheet 94 to return to the original shape. The cushioning sheet may be provided in the light emitting member mounting gap. Here, light emission can be observed from the outside through the light-transmitting region 72 provided on the back portion corresponding to the position of the light emitting member. In the book cover of FIG. 9, since the light emitting member mounting gap having a predetermined thickness is provided on the back, the book cover may be wrinkled or torn due to the thickness of the light emitting member or the surface irregularities. Can be prevented.

  Further, a light transmission pattern sheet 91 (shown in FIG. 9D) that transmits light in a specific pattern shape is prepared, and the light transmission pattern sheet 91 is mounted between the light transmission region 72 and the light emitting member 17. Thus, a desired light emission pattern can be obtained. The light transmissive pattern sheet 91 includes a light transmissive portion 92 and a light shielding portion 93 having a specific shape. As a method for forming the light transmitting portion 92, an opening corresponding to the shape of the light emission pattern is formed in the light shielding film, the light shielding film provided on the entire surface of the transparent film is removed according to the light emission pattern shape, or the light emission pattern shape. For example, a method such as sticking an adhesive seal having the above to a transparent film can be used.

  In the third embodiment, since the light emitting member is hidden behind the book cover main body, the appearance is the same as that of a normal book cover. For this reason, even in a state where the light emitting member is still attached to the book cover, the book can be read in a train or a restaurant without worrying about the eyes and without feeling strange to others. Here, if you do not want others to know the book you are reading, the book cover body may be made of an opaque material. Of course, if the light emitting member is removed, the same usability as a normal book cover can be realized.

  The fourth embodiment is a book cover main body used for the book cover according to any one of the second and third embodiments, and the book specific information of the book to be attached is printed on the book cover main body. And a book equipped with the book cover as a standard. This unique information may be printed on any of the back portion, the cover portion, and the folded portion of the book cover. A book sales form can be made with the book cover on which the book-specific information is printed mounted on the book. That is, the book cover according to the present embodiment is provided as a standard on a book as a book cover or a book band. For this reason, the appearance and usability of the book in the state in which the book is purchased are the same as those of the conventional book, but the light emitting function is exhibited by attaching only the light emitting member separately. This provides additional convenience for book readers.

  Next, an embodiment of the light emitting member of the present invention will be described.

  As shown in FIG. 10, in the light emitting member of the fifth embodiment, the light emitting member 16 includes a base material 19, a light emitting element 18 formed on the base material 19, a switch 102, and a power source 101.

  As the base material 19, a resin sheet, a ceramic substrate, a glass substrate, or the like can be used, but a flexible resin sheet is preferable because it is not easily damaged when an impact or a continuous bending stress is applied.

  As the light-emitting element, a light-emitting diode, an organic electroluminescent element, an inorganic electroluminescent element, a field emission element, a fluorescent display tube, or a liquid crystal display element with a backlight light source can be used. A luminescence element or an inorganic electroluminescence element is preferable from the viewpoint of miniaturization and thickness reduction. Of these, organic electroluminescent elements are particularly preferred. This is because the organic electroluminescence element has low power consumption, can emit light with high brightness, and has many kinds of emission colors.

  The structure of the organic electroluminescence element is shown in FIG. A structure that emits light from one surface of the substrate 121 where the organic light emitting layer 123 is formed will be described with reference to FIG. First, the back electrode 122 is formed on the substrate 121. A conductive material having a high reflectance such as aluminum, silver, chromium, nickel, or copper is used for the back electrode 122 in order to extract light emitted from the organic light emitting layer 123 to the observation side. The electrode shape is a shape corresponding to the light emission pattern. In other words, the pattern has a shape according to a pattern reminiscent of the purpose of attaching a pattern or book cover unrelated to the unique information. In particular, a pattern having no special meaning in itself such as a geometric pattern such as a circle, a polygon, or a star, a simple number, a simple letter, or a combination thereof is particularly preferable. After forming the back side electrode 122, the organic light emitting layer 123 and the light extraction side electrode 124 are sequentially formed on the back side electrode 122. As the light extraction side electrode 124, a metal oxide transparent conductive film such as ITO, ZnO, IZO, or SnO 2 processed into the same outer shape as the pattern of the back side electrode 122 is used. FIG. 13A is a diagram in which the light extraction side electrode is formed in a solid and square shape. Here, as shown in FIGS. 13B and 13C, instead of the transparent conductive film, an electrode in which conductive ink is formed in a mesh-like pattern or a comb-like pattern may be used. The electrode pattern by the conductive ink is not particularly limited as long as it exhibits a transmittance to such an extent that light emission from the organic light emitting layer can be observed, and even a pattern other than the above pattern can be used. Conductive ink is less expensive than a transparent conductive film made of a metal oxide because it is inexpensive, does not require a vacuum film formation device, and can be formed by a printing method such as screen printing, gravure printing, or inkjet. Since an electrode can be formed cheaply and easily, it is preferable. Next, the organic electroluminescence device 120 is completed by covering the entire device with the transparent sealing layer 125 from the upper surface of the light extraction side electrode 124.

  As the power source 101, a storage battery, a battery, a solar cell, or the like can be used. Among them, a lithium ion battery, an alkaline manganese battery, an organic radical battery, a flexible battery using a polymer or liquid electrolyte, and the like are used. The shape is preferably a thin and small battery represented by a button battery. A battery holder (not shown) for mounting the battery is fixed at a predetermined position on the substrate so as to be positioned on the back of the book cover so that the battery can be replaced. Here, if the battery is thin and small, the battery will not protrude, making it difficult to handle the book cover, or giving an uncomfortable appearance. In addition, by providing the battery only on the back, there is no inconvenience that occurs when the battery is provided on the cover. That is, when a book is stored in the bookshelf, there is no inconvenience that the book is damaged or the battery is damaged by the pressure applied from the book adjacent to the protruding battery. When the size of the battery extends from the back part to the cover part, the above disadvantage can be prevented by using a flexible thin battery that can be bent.

  The switch 102 is preferably a flat switch. As the flat switch, various types of touch sensors of resistance film type, capacitance type, ultrasonic type or infrared type, or flat type or emboss type membrane switch can be used. A membrane switch is preferable when the switch and the light emitting element are formed at different positions on the plane. Since the membrane switch is turned on and off by the force of a finger, it is unlikely to cause an unintended malfunction. An embossed membrane switch is particularly preferred for applications such as large print books and Braille books for visually impaired people. The embossed membrane switch has an embossed part whose upper part is processed into a convex shape. For this reason, since the embossed part moves up and down when pressed with a finger, the position of the switch can be specified by tactile sense and the switching operation can be confirmed.

  In the sixth embodiment, the membrane switch and the light emitting element are stacked. Note that the order of stacking may be either.

  FIG. 14 shows an embodiment in which the membrane switch 140 and the organic electroluminescence element 120 are stacked. In FIG. 14, the organic electroluminescent element 120 is laminated on the membrane switch 140 so that light emission can be observed from the organic electroluminescent element 120 side. The embodiment of FIG. 14 is preferable because the switch can be turned on and off by a simple operation by simply pressing the light emitting surface. Furthermore, since the light emitting surface also serves as a switch, the area of the light emitting member can be reduced as compared with the case where the light emitting element and the switch are provided at different positions on the substrate. Here, as shown in FIG. 14, the base material 145 located at the boundary between the membrane switch 140 and the organic electroluminescence element 120 has an upper electrode 144 of the membrane switch and the organic electroluminescence on both surfaces of the base material 145, respectively. Since the one formed with the back electrode 122 of the sense element is used, the boundary substrate is one. This achieves a reduction in the thickness of the laminated portion of the switch and the light emitting element.

  In the structure in which the organic electroluminescent element is laminated on the membrane switch, light emission with higher luminance can be obtained. In this case, the membrane switch is preferably a flat type. In the flat type, since the vertical movement width of the switch accompanying the on / off operation is small, the amount of deflection of the organic electroluminescent element stacked on the switch is also small, resulting in deterioration of the organic electroluminescent element. Can be prevented. In the use of books for visually handicapped persons such as large print books and Braille books, it is particularly preferable to provide a convex portion having a height that can be recognized by the tactile sense of a finger on the upper surface or the periphery of the switch. This is because a visually impaired person can easily recognize the position of the switch. The convex portion can be provided by a method of arranging a plurality of spot-like projections on the upper surface of the switch or forming a frame-shaped wall-like convex portion around the switch. What is necessary is just to make the width | variety and height of the said convex part comparable as the Braille normally used.

  On the other hand, the structure in which the membrane switch is laminated on the organic electroluminescence element has an advantage that the position of the switch can be easily recognized because an embossed membrane switch can be used. In addition, in this structure, the lifetime of the organic electroluminescent element can be extended because of less deflection. Instead of the embossed membrane switch, a resistive film type or capacitive type touch sensor may be used in which a convex part having a height recognizable by a finger touch is provided around the sensor. Here, the electrode of the touch sensor is formed of a transparent conductive film, so that even if the switch is stacked on the light emitting element, light emission is not blocked by the switch, so that high luminance light emission is obtained. be able to.

  In the seventh embodiment, as shown in FIG. 11, a drive circuit 111 for driving the light emitting element 18 is provided on the substrate. An embodiment using a drive circuit is shown below. If the driving circuit is operated so that the light emitting element emits light intermittently, the consumption of the battery can be suppressed. That is, it is possible to emit light for a long time. Also, it is possible to drive a plurality of types of light emission profiles according to the combination of the light emission time and the light extinction time, and to select the light emission profile according to the situation where the book cover is attached. Can be suppressed.

  FIG. 15 shows a selection example of the light emission profile. In this example, as shown in FIG. 15A, three types of light emission profiles (light emission profile 1, light emission profile 2, and light emission profile 3) can be driven. Here, each time the switch is pressed once, as shown in FIG. 15B, the three light emission profiles are switched in order. In this way, it is preferable that a desired light emission profile can be selected. With such a configuration, when the book cover is attached for a short period, the light emission profile 1 that continuously emits light is selected, and when the attachment period is long, the light emission is repeated for short time emission and long time extinction. Use such as selecting the profile 3 becomes possible.

  In the eighth embodiment, an electromagnetic wave sensor is provided on the substrate so that light emission can be remotely controlled by a remote control device. By providing the electromagnetic wave sensor, the light emitting member can be made to emit light by operating the remote control device only when it is desired to find the target book, so that unnecessary light emission is prevented. As a result, the battery consumption of the light emitting member can be suppressed to the minimum necessary. As a combination of a transmission device and an electromagnetic wave sensor for performing remote operation, an infrared remote control device and an infrared sensor, an RFID reader / writer, an RFID tag, or other wireless communication means can be used.

  Here, an embodiment in which an RFID tag is used as the electromagnetic wave sensor will be described with reference to FIG. First, the RFID tag 160 is provided on the base material 19 of the light emitting member 17. The RFID tag 160 is connected to the light emitting element 18 through the drive circuit 111 by electric wiring (not shown) formed on the base material 19. Furthermore, inside the RFID tag 160, book cover attachment target identification information associated with the light emitting member 17 provided with the tag 160 is stored in advance.

  The book cover attachment target identification information has the following meaning. For example, when a book cover of this embodiment is attached to five different books in a library, three of the five books are attached with book covers for the purpose of showing school recommended books, and the remaining two books are new collections. For the purpose of showing. The above-mentioned “school recommended books” and “new collections” mean information that can be distinguished between these two types is book cover attachment target identification information. Thus, the book cover attachment target identification information preferably includes at least information that can identify the purpose of attaching the book cover. In addition, the book cover attachment target identification information includes book-specific information that can identify individual books. May be.

  Next, a light emission instruction signal is transmitted from the reader / writer. This light emission instruction signal includes book cover attachment target identification information corresponding to a target book to be emitted. When receiving the light emission instruction signal, the RFID tag collates the book cover attachment target identification information included in the light emission instruction signal with the book cover attachment target identification information stored in advance in the tag, thereby obtaining two pieces of information. Are the same, a light emission control signal is transmitted via the electrical wiring. If the two pieces of information are different, no light emission control signal is transmitted. In this way, light emission is controlled.

  According to the light emitting member of this embodiment, the light emitting member can emit light for each purpose of attaching the book cover. For this reason, even when books for a plurality of purposes are mixed and stored in the bookshelf, only books for a specific purpose can be emitted, so that the life of the power source can be extended and the time for searching for books can be saved. It can be shortened. In addition, the light emitting member of this embodiment receives a light emission instruction signal wirelessly and transmits a light emission control signal by wire. For this reason, compared with the operation range of the RFID tag by the conventional two-way wireless communication, operation in a wider range is possible. For this reason, even if the target book is scattered in the room in a library or a bookstore, these books can be easily found.
