Description

Technical Field

[0001] The present invention relates to a three-dimensional collection card system, which is characterized in that collection cards are composed of three-dimensional (3D) cards, equipped with a three-dimensional observation device for observing such three-dimensional cards, and a case for storing such three-dimensional cards and the three-dimensional observation device is configured in the form of the structure of a book.

Background Art

[0002] Various cards such as those related to games, sports, tourist attractions, performances, theme parks, and Christmas cards, birthday cards, tourist cards, advertising cards, museum collection cards, and manga cards are published in the form of collection cards. However, such collection cards only provide 2D photos and 2D printed images, and no method for constructing collection cards that can be viewed three-dimensionally is disclosed.

[0003] It is known that three-dimensional images have a very large visual effect, such as when the image is twice as large, the visual effect is more than twice as large. However, the larger the screen, the more the center of the left and right images, the center of the left and right lenses, and the distance between the user's left and right eyes do not match, so it is impossible to provide a three-dimensional image with a large screen. As an example, as shown in the example of the reference figure in FIG. 7, a conventional three-dimensional viewing device in which a three-dimensional image is provided by a wheel-type rotating device is 80 mm thick and heavy with a weight of 100 g or more, so it could not be applied to the structure of collection cards and books.

[0004] Also, since the number of frames of the provided video is only 14 frames (7 scenes), it was only used for providing simple pictures. Furthermore, the 3D image is produced on a tiny film measuring only 12mm x 10mm. Because the image is so small and must be printed on the film surface, the resolution is poor, and the image is only visible if light passes through the back. Consequently, mass production using the printing method is not possible, and recently, the production of the film has been restricted due to the toxic chemicals it contains. The international standard for postcards, a type of collectible card, ranges from a maximum of 150mm x 105mm to a minimum of 140mm x 90mm. Furthermore, printed materials such as collectible cards and card books become difficult to bind and print as books if they deviate from the standard size specifications for publications. The typical thickness of a published book is 20-50 mm. Exceeding this thickness makes the book aesthetically unappealing and excessively heavy, making distribution and storage inconvenient.

[0005] It is well known that the standard sizes for such books are based on width x height, with 4.6x size (B5) being 257mm x 182mm, 4.6x size (B6) being 182mm x 128mm, Kikubai size (A4) being 297mm x 210mm, Kikuban size (A5) being 210mm x 148mm, and Kikuhan size (A6) being 148mm x 105mm. Conventional 3D devices have excessive volume and weight due to the length from front to back determined by the focal length of the lenses, and the length from side to side of the left and right lenses, making them unsuitable for books of the thickness and format shown above. Images in printed publications are not made of light-transmitting film or have self-illuminating capabilities like those in smartphones; therefore, stereoscopic observation is impossible without illumination from ambient light. However, existing 3D devices have a structure that blocks external light and allows light to pass through the back of the film, so they could not be applied to 3D collectible cards and other items that do not have their own light source, like printed materials.

[0007] In view of the above-mentioned problems, the present invention presents a method for constructing a three-dimensional collection card that is printed as a three-dimensional image and can be clearly observed. [Means for solving the problem]

[0008] The entire system consists of a collection of 3D cards, a 3D observation device, and a book-shaped case that houses the collection cards and the device. The collection cards form a vertical central line, with images for the left eye and right eye on both sides of the central line. The stereoscopic observation device is based on a barrier plate, with a handle at the bottom, and in front of the barrier plate, left and right lens plates, each equipped with left and right lenses, are provided so as to be folded on both the left and right sides of the barrier plate. A fixed base is constructed behind the barrier plate, allowing for the insertion and removal of three-dimensional cards. The system is configured so that a stereoscopic observation device is housed in a separate, isolated book case in order to observe the 3D collection cards in 3D. The stereoscopic observation device is equipped with a handle at the bottom, and above the handle, it is constructed as a thin plate-like barrier film that is long in the longitudinal direction from front to back, with a length equal to the focal length of the left and right lenses, and a thickness of 1 mm to less than 10 mm. The front section of the shielding membrane consists of left and right lenses and left and right lens plates that can be folded in the left-right direction, and the rear section of the shielding membrane is equipped with a fixing base for mounting three-dimensional collection cards from top to bottom in a downward direction, and is configured in combination with an elastic device. The book case consists of a card case for storing 3D collection cards inside the book cover and a 3D device case for storing the 3D observation device, both of which are designed in the form of a book. The stereoscopic observation device is configured such that the center of each of the left and right eye images on the stereoscopic collection card, the center of the left and right lenses, and the distance between the user's left and right eyes are aligned, by fixing a central fixing groove, which is located at the lower end of the stereoscopic collection card, to a fixing pin provided at the bottom of the fixing base of the stereoscopic observation device. Another way to construct a book case is to include a card case and a three-dimensional device case inside the cover of a single book. Another way to construct the book case is to use transparent plastic for the cover structure of the card case and the 3D device case. Another way to construct the book case is to use a card case for storing 3D collection cards and a 3D device case equipped with a 3D observation device. Another way to construct the book case is to use a separate book case for the three-dimensional collection cards. [Effects of the Invention]

[0009] The 3D images provided on these collectible cards are presented on a screen more than 30 times larger than conventional 3D images in film format. By making the minimum thickness of the stereoscopic observation device approximately 25 mm, the same as the standard thickness of a book, it has the advantage of being easily stored and displayed in book form, easy to carry and store, and readily available for distribution. Such card cases can hold 25 to 50 3D collection cards, and when 3D images are constructed using the front and back, up to 100 scenes (200 frames) can be provided. This allows for more than 10 times the number of 3D images compared to the 7 scenes provided by conventional 3D devices.

[0010] The stereoscopic viewing device, with its left and right sides completely open and designed to allow ambient light to illuminate the surface of the 3D collection cards, illuminates the surface of the printed 3D image on the collection cards without the need for a separate lighting device, allowing for the viewing of bright images. The 3D observation device, in which the handle and barrier membrane are constructed from a single thin plate structure, weighs only one-third the weight of conventional existing 3D devices, as shown in the reference diagram in Figure 7. Therefore, it can be easily used with one hand by children and the elderly. The handle located at the bottom of the 3D observation device allows you to use the entire structure of the device with a single hand to swap out the 3D collection cards at any time, making it possible to easily swap and utilize a large number of 3D collection cards. The structure of the fixing base of the 3D observation device, which pulls in and secures the 3D collection cards from above, has the effect of stably fixing the 3D collection cards. Furthermore, since the present invention allows for three-dimensional viewing simply by inserting a three-dimensional collection card, its usage is very simple.

[0011] Furthermore, since the present invention is provided at more than 30 times the size of conventional wheel-type 3D viewers, its audiovisual effect is significantly greater. The elastic device, which is part of the fixing mechanism for attaching the three-dimensional collection cards, has an elastic structure like a resilient circular spring, providing elasticity, durability, and stability even when the three-dimensional collection cards are changed at any time. The central fixing groove formed at the lower end of the center line of the 3D collection card or at the bottom of the 3D observation device is fixed to the central fixing pin of the mounting base, ensuring that the 3D collection card is always mounted in the center of the 3D observation device. This automatically aligns the left and right centers of the 3D collection card, the respective centers of the left and right lens plates, and the left and right eyes of the user, enabling the 3D image of the 3D collection card to be observed in 3D. The lengths before and after the blocking film of the three-dimensional observation device are configured to be the same as the focal lengths of the left and right lenses, so that the focal lengths of the left and right lenses automatically coincide without a separate focusing action during use.

[0012] Such a three-dimensional collection card is provided with an image of the maximum size within the range of the observer's viewing angle. The three-dimensional observation device is configured with the minimum volume and structure, and is configured in the form of a book by applying it to various printed formats of existing books. Therefore, it can be used, carried, and stored like a book, and has the effect of being able to circulate as a book. In addition, by unitizing a large number of three-dimensional collection cards and three-dimensional observation devices in the form of separate books respectively, the three-dimensional collection cards can be separately and repeatedly provided without duplicating the three-dimensional observation device, so that they can be continuously used, collected, and stored.

[0014] As shown in the drawings, the present invention is characterized in that a three-dimensional collection card 200, a three-dimensional observation device 300, and a book case 100 for storing them are combined into a single structure and constitute a three-dimensional collection card. The three-dimensional collection card 200 of the present invention is designed to be the size of a book, and the three-dimensional image of the collection card is constructed to be the largest size that can be viewed within the distance between a person's left and right eyes. The three-dimensional collection card 200 consists of three-dimensional pictures or photographs, and the three-dimensional observation device 300 has an open structure that allows ambient light to enter, and is designed to have the minimum volume, thickness, and weight to fit inside a book case 100 that is within the standard size specifications for publications. This will be explained in detail with reference to the drawings.

[0015] As shown in Figures 1(a) and 1(b), the 3D collection card 200 has a central line 9 displayed vertically in the center of one side of the card, and a 3D left-eye image 10 and a right-eye image 11 on both the left and right sides of the central line 9, with a finishing frame 12 around the top, bottom, left, and right edges of the left and right-eye images 10 and 11. As one example, the thickness of the 3D collection card 200 should be 0.5mm-2mm, and a card made of plastic or cardboard is recommended. The dimensions of the 3D Collection Card 200 are based on the international postcard standard of 140 x 90 mm, but are not limited to this. The distance between the centers of the left-eye image 10 and the right-eye image 11 for stereoscopic viewing is set to less than 65 mm, which is the distance between the user's left and right eyes, and the stereoscopic viewing device 300 is configured so that the centers of the left and right eye images 10 and 11 coincide with the centers of the left and right lenses 20 and 22 and the user's left and right eyes. These left and right eye images 10,11 include all printable images, such as photographs, illustrations, comics, and drawings.

[0016] To give a specific example, if the overall size of the 3D collection card 200 is 140 x 90 mm, the center line 9 of the 3D card 200 is 4 mm, the width of the left and right finishing frames 12 is 5 mm, the top finishing frame 12 is 20 mm, and the width of the bottom finishing frame 12 is 10 mm, then the size of the 3D images 10 and 11 for the left and right eyes will be 63 mm wide x 60 mm high. This type of 3D illustration measures 63 x 60 mm (3780 mm). 2 The size is 10 x 12 mm (120 mm) for a conventional 3D device's 3D film. 2 In contrast to the previous version, it will now be presented as a large, three-dimensional image approximately 31.5 times larger. The central fixing groove 13 formed at the lower end of the center line 9 of the three-dimensional collection card 200 is connected to and fixed with the central fixing pin 17a of the fixing base 17, so that the center line 9 of the three-dimensional collection card 200 always coincides with the vertical surface of the barrier film 15. Therefore, the left and right centers of the left and right eye images 10, 11, the left and right lens plates 20, 22, and the user's left and right eyes automatically align. Such a fixing groove 13 can be provided at the bottom of the stereoscopic observation device 300.

[0017] The 3D observation device 300 must be lightweight so that children can pick it up and observe with one hand, and the 3D collection cards 200 can be swapped out at any time with one hand. Therefore, its structure must be simple and robust, and its weight must be as light as possible. Therefore, the present invention provides a handle 14 below the center of gravity of the stereoscopic observation device 300, and a barrier membrane 15 above it, so that the stereoscopic collection cards 200 can be replaced at any time. The structure of this barrier membrane 15 is configured to block and separate the left and right eye images 10 and 11 of the stereoscopic collection cards 200, as shown in Figure 2(a).

[0018] Therefore, the thickness t of such a barrier film 15 is preferably 2-5 mm thick, depending on the material, and is within 1 mm to 10 mm, as shown in Figure 2(b). The vertical length of such a shielding film 15 is the same as, or less than, the vertical length of the center line 9 of the three-dimensional collection card 200, so that the shielding film 15 vertically blocks the space between the left and right eye images 10 and 11, preventing the left and right eye images from overlapping and appearing as double images.

[0019] As shown in Figures 2(a), 3 and 4, the stereoscopic observation device 300 is equipped with left and right lenses 20 and 22 in front of the shielding film 15, and consists of left and right lens plates 19 and 21 that fold to the left and right, a hinge 18, and a retraction groove 23 into which the user's nose is pulled. The downstream section of the barrier membrane 15 consists of a fixed base 17 on which the three-dimensional collection card 200 is mounted, an elastic device 16, and a handle 14, and the position of the three-dimensional observation device 300 is configured to be the center of gravity of the whole. Therefore, the stereoscopic observation device 300 is composed of a shielding membrane 15, a fixed base 17, and left and right lens plates 19 and 21 equipped with left and right lenses 20 and 22. By configuring a handle 14 at the lower position of the center of gravity of these components, the entire stereoscopic observation device 300 can be used with one hand using the handle 14, and the stereoscopic collection cards 200 can be changed at any time with the other hand. As shown in Figure 4, the entire area around the shielding film 15 of the stereoscopic observation device 300 is open, allowing ambient light to illuminate the surface of the stereoscopic collection card 200 mounted on the fixed base 17, thus enabling clear stereoscopic image observation.

[0020] As shown in Figure 2(a) and Figure 4, a fixing base 17 for mounting the three-dimensional collection card 200 is configured downstream of the barrier membrane 15. The fixing base 17 pulls the three-dimensional collection card 200 in from above and fixes it in place, and an elastic device 16 with an elastic angle of circular or right-angle or greater is configured between the fixing base 17 and the barrier membrane 15, so that the three-dimensional collection card 200 can always be fixed in an elastic manner. When the structure of this elastic device 16 is configured in a circular shape, as shown in Figure 4, it functions like a spring, constantly providing elasticity to the fixed base 17. Therefore, even when the three-dimensional collection cards 200 are repeatedly pulled in and out, the durability of the elasticity can be maintained. The structure of this fixed stand 17 is such that the 3D collection cards 200 are mounted from top to bottom. Therefore, auxiliary devices can be added as needed to mount a large number of 3D collection cards 200, and the structure can be expanded to allow for continuous viewing of 3D images by pulling them out one by one.

[0021] As shown in Figures 2 and 3, in front of the shielding film 15, a left lens plate 19 equipped with a left lens 20 and a right lens plate 21 equipped with a right lens 22 are connected by hinges 18, and are configured to rotate to the left and right of the shielding film 15, folding and unfolding. As shown in Figure 2(b), the three-dimensional observation device 300 is configured such that when folded, its maximum thickness a is within 20-50 mm, and the overall thickness of the book case 100 that houses it is also configured to be between 20 mm and 50 mm. As shown in Figure 2(b), the thickness a of the stereoscopic observation device 300 determines the thickness of the book case 100. Therefore, when the left and right lens plates 19 and 21 are folded to the left and right of the barrier film 15, it is preferable to configure the stereoscopic observation device 300 so that the thickness a is within 25 mm. The width a1 of the elastic device 16 and the fixed base 17 is also the same width as or less than a in Figure 2(b). Therefore, the maximum thickness a of all components of the stereoscopic observation device 300 must be within a, as shown in Figure 2(b).

[0022] In the structure shown in Figure 3, when not in use, the left and right lens plates 19 and 21 are folded to the left and right of the shielding film 15 by the hinge 18, as shown in Figures 2(a) and (b), resulting in the minimum thickness a. In other words, by folding the left and right lens plates 19 and 21, the thickness a of the left and right sides of the stereoscopic observation device 300 is reduced, and therefore the thickness and volume of the book case 100 are also reduced. Consequently, it becomes easier to store, ship, and keep the book.

[0023] As shown in Figure 4, the length b of the shielding film 15 is from the surface of the three-dimensional collection card 200 to the left and right lens plates 19 and 21. By configuring the length b of the shielding film 15 to be the same as the focal length c of the left and right lenses 20 and 22, the focal length c of the left and right lenses 20 and 22 is configured to automatically match the length b of the shielding film 15. The focal lengths of the left and right lenses 20 and 21 in such a stereoscopic observation device 300 are set to be between 30 mm and 150 mm. If the focal length is set to 30 mm or less, the magnification is high and the resolution of the left and right eye images 10 and 11 is impaired. If the focal length is set to 150 mm or more, the length of the shielding film 15 becomes longer, which hinders the construction of the device in book form due to the increase in overall volume. Furthermore, as shown in Figures 3 and 4, a retraction groove 23 is formed in the lower center of the left and right lens plates 19 and 21, and in the lower front section of the shielding film 15, so that the user's nose is pulled in. When the user's nose is pulled into such a retraction groove 23, the user's left and right eyes can be brought into close contact with the left and right lenses 20 and 22, thereby expanding the field of view due to the diameter of the left and right lenses 20 and 22, and allowing the user to view a large stereoscopic image. Furthermore, the handle 14 provided below the shielding membrane 15 can be configured to connect to and separate from the shielding membrane 15.

[0024] The thickness a of the stereoscopic observation device 300, as shown in Figure 2(b), determines the number of stereoscopic cards 200 that can be attached. For example, when the thickness a of the stereoscopic observation device 300 is 25 mm, the thickness of the card case 1 can be made within 30 mm, even considering the thickness of the book covers 7,7a. This card case 1, with its 25mm thickness, can hold up to 50 cards of the 0.5mm thick 3D card type 200, or up to 25 cards of the 1mm thickness type.

[0025] When images 10 and 11 for the left and right eyes are arranged on the front and back surfaces of the 3D collection card 200, it will provide twice that number, or 100 different 3D images. Therefore, it becomes possible to imbue them with a story as collectible cards, and various projects such as 3D insect encyclopedias, 3D plant encyclopedias, 3D travel guides, or 3D comics can be published. The thickness of this card case 1, including the thickness of the book cover 7, can be between 10mm and 60mm. If it is less than 10mm, the number of 3D collection cards 200 will be limited, and if it is more than 60mm, the thickness of the book will be large, making storage inconvenient.

[0026] As shown in Figures 2(a), (b), 3, and 4, the components of the stereoscopic observation device 300 are simply and robustly constructed using only the necessary elements. As a result of actual implementation, it was possible to construct a very light structure weighing only 30g. This is less than one-third the weight of existing stereoscopic viewer devices, such as the one shown in Figure 7, which weighs 110g. As shown in Figures 5(a), (b), and (c), the present invention can be configured as separate book units, consisting of a card case 1 that stores the 3D collection cards 200 in the form of a book, and a 3D device case 3 that stores the 3D observation device 300. The book case 100 consists of the card case 1 shown in Figure 5(a) and the folding surface 5 of the three-dimensional device case 3 or the book cover 7, as shown in Figure 5(b), with a coupling device 6,6a made of a magnet and magnetic material attached to one side of the book cover 7. Furthermore, such a coupling device can cover or leave the book covers 7,7a, as shown in Figures 5(a) and 5(b), and such a coupling device 6a can be made of other known structures.

[0027] As shown in Figure 6(a), the present invention incorporates the structure of a card case 1 in the upper and lower parts of the book case 100, and the structure of a three-dimensional device case 3, all within the structure of a single book. In other words, as shown in Figure 5(a), the three-dimensional collection cards 200 are stored in a separate card case 1, and the collection is organized into a separate book case 100. In other words, as shown in Figure 5(b), the stereoscopic observation device 300 is housed in a separate stereoscopic device case 3, and is comprised of a separate book case 100.

[0028] As shown in Figure 5(c), the structures of Figure 5(a) and Figure 5(b) are combined into a single book case 100 using coupling devices 6 and 6a. Since card case 1 and 3D device case 3 are separate, users who own 3D device case 3 have the advantage of being able to continuously collect only the 200 3D collection cards for card case 1 as needed. The book covers 7,7a in Figures 5(a), 5(b), and 6(a) can be made of transparent plastic so that the contents stored inside can be seen from the outside.

[0029] As an example, in order to accommodate the 3D collection card 200, which measures 140 x 90 mm in width x height, the dimensions of card case 1 and 3D device case 3 are set to 150 mm x 120 mm and 20-60 mm in thickness, thereby configuring the device to accommodate both the 3D collection card 200 and the 3D observation device 300. The size of this book-shaped card case 1 and three-dimensional device case 3 can be applied to the Chinese size (A5) of publications, which is 210 x 148 mm, and the book thickness is 20-60 mm, thus the present invention can also be applied to the size of printed materials, which is 4.6 size (B6) of 182 x 128 mm. By the same logic, book cases 100, which are 240 x 150 mm in size as shown in Figures 6(a) and 6(b), can be adapted to a size of 257 mm x 182 mm, which is the A4 size for printed materials, and can be published as a publication. When the handle 14 of the stereoscopic observation device 300 is configured to be joined and separated, it can be applied to a wider variety of book format standards.

[0030] The figures implemented above are merely examples, and the same logic will apply when new sizes or new specifications of three-dimensional collectible cards are released. The present invention is similarly applicable when the book cover structure 7,7a is constructed from transparent plastic. Furthermore, the numerical values ​​presented in this invention are not limiting, and for the sake of explanation, they can be varied and applied within the logic of this invention.

[0031] Therefore, the present invention, a stereoscopic observation device 300 composed of a thin film barrier 15, a fixing device 17 with an elastic device, and left and right lens plates 19 and 21, is mechanically robust in structure, yet is simply constructed with the minimum volume of barrier 15. As a result, the weight is reduced to one-third of that of existing stereoscopic devices, making it easy for children and the elderly to use with one hand by using the handle. Furthermore, as shown in Figures 1(a) and 1(b) and Figure 3, the three-dimensional image of the present invention provided by the printed material attached to the stereoscopic observation device 300 can be observed as a clear image using ambient light even without a self-light source or a transmitted light source, and unlike film structures, it can be mass-produced in printed form. Furthermore, as shown in Figure 4, in this invention, the length b of the shielding film 15 and the focal lengths c of the left and right lenses 20 and 22 are the same. Therefore, when the left and right lenses 20 and 22 are unfolded, the focal lengths of the left and right lenses 20 and 22 automatically coincide with the position of the 3D collection card 200, making it easy to observe a 3D image. Furthermore, as shown in Figure 5(a), a large number of 3D cards 200 and as shown in Figure 5(b), a 3D observation device 300 can be packaged as a separate product in the form of a book case 100. Alternatively, as shown in Figures 6(a) and (b), the 3D cards 200 and the 3D observation device 300 can be packaged as a single book case 100, thus packaged as a product in the form of a book. Furthermore, since the present invention is provided at 30 times the size of conventional film wheel-type stereoscopic viewing devices, the viewing angle effect is more than 30 times greater, and such a viewing angle effect is very significant when used for educational purposes.
