Description

[Technical Field]

[0001] The present invention relates to a three-dimensional collection card system in which collection cards are made up of three-dimensional (3D) cards, a three-dimensional observation device is provided for observing such three-dimensional cards, and a case for storing such three-dimensional cards and the three-dimensional observation device is constructed in the shape of a book. [Background technology]

[0002] Various cards are published in the form of collectible cards, including images of games, sports, tourist spots, performances, and theme parks, as well as Christmas cards, birthday cards, tourist cards, advertising cards, museum collection cards, and manga cards. However, these collectible cards only provide 2D photographs or 2D printed images, and no method for constructing collectible cards that can be viewed in three dimensions is disclosed.

[0003] It is well known that a 3D image has a great visual effect; if the image is twice as large, the visual effect is also more than twice as large. However, the larger the screen, the more the distance between the centers of the left and right images, the centers of the left and right lenses, and the user's left and right eyes does not match, making it impossible to provide a 3D image on a large screen. For example, as shown in the reference diagram of Figure 7, a conventional stereoscopic viewing device that provides a stereoscopic image using a wheel-type rotating device is thick (80 mm) and weighs more than 100 g, so it cannot be applied to the structure of collectible cards and books.

[0004] Also, since the number of frames provided was only 14 (seven scenes), it was only used to provide simple images. In addition, the 3D screen is in the form of a small film measuring just 12mm x 10mm, and because the screen is small and it has to be printed on the surface of the film, the resolution is low and the image cannot be seen unless light is transmitted through the back side. Therefore, mass production using the printing method is not possible, and recently film production has been restricted due to the toxic chemicals contained in the film. The international standard for postcards, a type of collectible card, is a maximum of 150mm x 105mm and a minimum of 140mm x 90mm. Furthermore, if printed materials such as collectible cards and card books deviate from the publication format standards, it becomes difficult to bind and print them as books. The normal thickness of a publication is 20-50 mm. If the book exceeds this thickness, the book will not look beautiful and will be too heavy, making it inconvenient to distribute and store.

[0005] It is well known that the standard sizes of such books, based on width and height, are 257mm x 182mm for the 4.6x size (B5 size), 182mm x 128mm for the 4.6x size (B6 size), 297mm x 210mm for the chrysanthemum double size (A4 size), 210mm x 148mm for the chrysanthemum half size (A5 size), and 148mm x 105mm for the chrysanthemum half size (A6 size). Conventional 3D devices could not be applied to the thickness and format of books mentioned above because the total volume and weight were excessive due to the front-to-back length caused by the focal length of the lenses and the left-to-right length of the left and right lenses. Images in printed publications are not light-transmitting films or self-luminous images like smartphones, so they cannot be viewed in three dimensions unless illuminated by external light. However, existing 3D devices are designed to block external light and allow light to pass through the back of the film, so they cannot be applied to 3D collection cards and other items that do not have their own light source like printed materials.

[0007] In view of the above problems, the present invention provides a method for printing a three-dimensional image on a collection card, which can be clearly observed. [Means for solving the problem]

[0008] The entire system is composed of a three-dimensional collection card, a three-dimensional observation device, and a book case of this form for storing the three-dimensional collection card and the three-dimensional observation device, and the three-dimensional collection card forms a center line in the vertical direction, and a picture for the left eye and a picture for the right eye are formed on both the left and right sides of the center line. The stereoscopic observation device is provided with a handle at the bottom based on the shielding plate, and left and right lens plates with left and right lenses are provided in front of the shielding plate so as to be folded to both the left and right of the shielding plate. Behind the shielding plate, a fixed base is formed that allows the 3D card to be pulled in and out. In order to observe the 3D collection cards in 3D images, the 3D observation device is housed in a separate book case. The stereoscopic observation device is provided with a handle at the bottom, and is configured to be long in the longitudinal direction from front to back above the handle, with its length being the same as the focal length of the left and right lenses, and is configured with a thin plate-structured barrier membrane with a thickness of 1 mm or more but less than 10 mm. The front stage of the blocking film is provided with left and right lenses and left and right lens plates that can be folded in the left and right direction, and the rear stage of the blocking film is provided with a fixing base on which a three-dimensional collection card is mounted downward from top to bottom, and is combined with an elastic device. The book case is composed of a card case for storing three-dimensional collection cards inside the cover of the book and a three-dimensional device case for storing the three-dimensional observation device, each of which is in the form of a book. The stereoscopic observation device is configured so that the centers of the pictures for the left and right eyes of the stereoscopic collection card, the centers of the left and right lenses, and the distance between the left and right eyes of the user coincide with each other by fixing a central fixing groove formed 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 method for constructing the book case is to provide a card case and a three-dimensional device case inside a single book cover. Another method of constructing the book case is to construct the card case and the book cover structure of the three-dimensional device case from transparent plastic. Another method of constructing the book case is to construct it from a card case for storing the 3D collection cards and a 3D device case for containing the 3D observation device. Another method of constructing the book case is to construct the 3D collection cards in a separate book case. [Effects of the Invention]

[0009] The 3D images provided by these 3D collection cards are presented on a screen that is 30 times larger than conventional 3D images in film format. The minimum thickness of the stereoscopic observation device can be set to within 25 mm, which is the standard thickness of a book, so that it can be stored in a book, displayed, carried, stored, and distributed easily. Such a card case can store up to 25-50 3D collection cards, and when creating a 3D image with the front and back panels, it can provide up to 100 scenes (200 frames), which is more than 10 times the number of 3D images that can be provided by conventional 3D devices, which provide only 7 scenes.

[0010] The stereoscopic observation device is constructed so that the left and right peripheries are all open and external light is irradiated onto the surface of the three-dimensional collection card, and bright images can be viewed because the surface of the three-dimensional image of the print collection card is irradiated without a separate lighting device. The 3D observation device, in which the handle and barrier are constructed as a single thin plate structure, is one-third the weight of the existing 3D device shown in the reference diagram of Figure 7, so that even children and the elderly can easily use it with one hand. The handle provided at the bottom of the three-dimensional observation device allows the entire structure of the three-dimensional observation device to be used with one hand, and the three-dimensional collection cards can be replaced at any time with one hand, so that a large number of three-dimensional collection cards can be replaced at any time and used. The structure of the fixing base of the 3D observation device, which pulls in and fixes the 3D collection card from above downward, has the effect of stably fixing the 3D collection card. Furthermore, the present invention is very easy to use, since it allows for a three-dimensional view simply by inserting a three-dimensional collection card.

[0011] Furthermore, the present invention is provided at a size 30 times larger than that of a conventional wheel-type stereoscopic viewer, so the audiovisual effect is great. The elastic device configured in the fixing device for mounting the three-dimensional collection cards has an elastic structure like a circular spring having elasticity, and always provides elasticity, durability and stability even when the three-dimensional collection cards are replaced 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 fixing base so that the 3D collection card is always attached to the center of the 3D observation device, so that the left and right centers of the 3D collection card, the centers of the left and right lens plates, and the left and right eyes of the user are automatically aligned, thereby enabling the 3D image of the 3D collection card to be observed in a 3D manner. The front-to-back length of the shielding film of the stereoscopic observation device is configured to be the same as the focal length of the left and right lenses, so that the focal lengths of the left and right lenses automatically match without any separate focus adjustment during use.

[0012] These 3D collection cards provide an image of maximum size within the range of the viewer's viewing angle, and the 3D observation device is configured with minimal volume and structure, and can be configured in the form of a book by applying it to various printing formats of existing books. Therefore, it can be used, carried, and kept like a book, and has the effect of being circulated as a book. In addition, by making a large number of three-dimensional collection cards and a three-dimensional observation device into separate book-like units, the three-dimensional collection cards can be repeatedly provided separately without duplicating the three-dimensional observation device, and thus the three-dimensional collection cards 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 it are combined into a single structure to form a three-dimensional collection card. The three-dimensional collection card 200 of the present invention is adapted to a book size, and is configured to have a size such that the three-dimensional image of the three-dimensional collection card can be seen at its maximum size within the distance between a person's left and right eyes. The 3D collection card 200 is made up of a 3D picture or a 3D photograph, and the 3D observation device 300 is made up of an open structure that allows external light to enter, and is made up of a minimum volume, thickness and weight, and is configured to be stored inside a book case 100 that is made up within the size standard of the publication, which will be described in detail with reference to the drawings.

[0015] As shown in Figures 1(a) and 1(b), the 3D collection card 200 has a center 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 sides of the center line 9, and a finishing frame 12 is formed around the top, bottom, left and right sides of the left and right eye images 10 and 11. In one embodiment, the thickness of the three-dimensional collectible card 200 is 0.5 mm-2 mm, and a card such as plastic or cardboard is recommended. The dimensions of the three-dimensional collection card 200 in terms of top, bottom, left and right 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 stereoscopic left eye picture 10 and the right eye picture 11 is set to be less than 65 mm, which is the distance between the left and right eyes of the user, and the stereoscopic observation device 300 is configured so that the centers of the left and right eye pictures 10, 11 coincide with the centers of the left and right lenses 20, 22 and the left and right eyes of the user. Such left and right eye pictures 10, 11 include all images that can be printed, such as photographs, illustrations, cartoons, and pictures.

[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 upper finishing frame 12 is 20 mm, and the width of the lower finishing frame 12 is 10 mm, the size of the 3D pictures 10 and 11 for the left and right eyes will be 63 mm left and right x 60 mm top and bottom. Such a 3D picture of 63 x 60 mm (3780 mm 2 The size of the 3D film of the conventional 3D device is 10 x 12 mm (120 mm 2 ) will be provided in a large 3D image that is approximately 31.5 times larger than the previous version. A central fixing groove 13 formed at the lower end of the central line 9 of the three-dimensional collection card 200 is connected to and fixed with a central fixing pin 17a of a fixing base 17, so that the central line 9 of the three-dimensional collection card 200 always coincides with the vertical surface of the blocking film 15. Therefore, the left and right centers of the left and right eye pictures 10, 11, the left and right lens plates 20, 22, and the left and right eyes of the user are automatically aligned. Such fixing grooves 13 can be provided in the lower part of the stereoscopic observation device 300.

[0017] The three-dimensional observation device 300 is light in weight so that even a child can pick it up and observe with one hand, and the three-dimensional collection cards 200 can be replaced at any time with one hand, so the structure must be simple and strong, and the weight must be as light as possible. Therefore, in the present invention, a handle 14 is provided below the center of gravity of the 3D observation device 300, and a barrier film 15 is provided above it, so that the 3D collection card 200 can be replaced at any time. The structure of this barrier film 15 is configured for the purpose of blocking and separating the images 10, 11 for the left and right eyes of the 3D collection card 200, as shown in Figure 2(a).

[0018] Therefore, the thickness t of the blocking film 15 is within the range of 1 mm to 10 mm, as shown in FIG. 2(b), and is preferably made of a thin plate of 2 to 5 mm depending on the material. The vertical length of the blocking film 15 is configured to be equal to or less than the vertical length of the center line 9 of the 3D collection card 200, and the blocking film 15 blocks the space between the left and right eye images 10, 11 vertically to prevent double images in which the left and right eye images overlap each other.

[0019] As shown in Figures 2(a), 3 and 4, the three-dimensional observation device 300 is provided with left and right lenses 20 and 22 in front of the barrier membrane 15, and is composed of left and right lens plates 19 and 21 that can be folded left and right, a hinge 18, and a retraction groove 23 into which the user's nose is retracted. The rear of the blocking film 15 is made up of a fixed base 17 on which the three-dimensional collection card 200 is attached, an elastic device 16, and a handle 14, and the three-dimensional observation device 300 is positioned at the center of gravity of the whole. Therefore, the three-dimensional observation device 300 is composed of a blocking membrane 15, a fixed base 17, and left and right lens plates 19, 21 equipped with left and right lenses 20, 22, and by configuring a handle 14 below the center of gravity of these components, it becomes possible to use the entire three-dimensional observation device 300 with one hand using the handle 14 and to replace the three-dimensional collection cards 200 at any time with the other hand. As shown in Figure 4, the periphery of the shielding film 15 of the 3D observation device 300 is entirely open, so that external light can illuminate the surface of the 3D collection card 200 attached to the fixed base 17, making it possible to observe clear 3D images.

[0020] As shown in Figure 2(a) and Figure 4, a fixed base 17 for mounting a 3D collection card 200 is provided behind the barrier film 15, and the fixed base 17 pulls the 3D collection card 200 from above downward to fix it, and an elastic device 16 having an elastic angle of a circular or right-angle structure or more is provided between the fixed base 17 and the barrier film 15, so that the 3D collection card 200 can always be fixed elastically. When the elastic device 16 is circular as shown in FIG. 4, it functions like a spring and constantly applies elastic force to the fixed base 17, so that the durability of the elastic force can be maintained even when the 3D collection card 200 is repeatedly pulled in and out. Since the structure of the fixed base 17 is such that the 3D collection cards 200 are attached from top to bottom, an auxiliary device can be added as needed to attach a large number of 3D collection cards 200 and pull them out one by one to continuously view 3D images.

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

[0022] When not in use, the structure of FIG. 3 has a minimum thickness a because the left and right lens plates 19 and 21 are folded to the left and right of the shielding film 15 by the hinges 18, as shown in FIGS. 2(a) and 2(b). In other words, by folding the left and right lens plates 19, 21, the left and right thickness a of the stereoscopic observation device 300 is reduced, which also reduces the thickness and volume of the book case 100. This makes it easier to store, ship, and keep as a book.

[0023] As shown in Figure 4, the length b of the barrier film 15 is from the surface of the 3D collection card 200 to the left and right lens plates 19, 21, and by configuring the length b of such barrier film 15 to be the same as the focal length c of the left and right lenses 20, 22, the focal length c of the left and right lenses 20, 22 automatically matches the front-to-back length b of the barrier film 15. The focal lengths of the left and right lenses 20, 21 in this stereoscopic observation device 300 are set to 30 mm or more and 150 mm or less. If the focal length is set to 30 mm or less, the magnification is high and the resolution of the images 10, 11 for the left and right eyes is impaired. If the focal length is set to 150 mm or more, the length of the shielding film 15 becomes long, which increases the overall volume and makes it difficult to configure the device in a book shape. 3 and 4, a recess 23 is formed in the lower central portions of the left and right lens plates 19 and 21 and in the lower front portion of the blocking film 15 so that the user's nose can be pulled in. When the user's nose is drawn into the drawing groove 23, the user's left and right eyes can be brought into close contact with the left and right lenses 20, 22, so that the viewing angle according to the aperture of the left and right lenses 20, 22 is expanded and a large stereoscopic image can be viewed. In addition, the handle 14 provided below the barrier film 15 may be configured to be connected to or separated from the barrier film 15 .

[0024] The thickness a of the 3D observation device 300 shown in FIG. 2(b) determines the number of 3D cards 200 that can be attached. For example, when the thickness a of the three-dimensional observation device 300 is set to 25 mm, the thickness of the card case 1 can be set to 30 mm or less, even taking into account the thickness of the book covers 7, 7a. Such a card case 1 has a thickness of 25 mm, and can accommodate up to 50 3D cards 200 having a thickness of 0.5 mm, and up to 25 cards having a thickness of 1 mm.

[0025] When the left and right eye pictures 10, 11 are arranged on the front and back surfaces of the 3D collection card 200, 100 different 3D images are provided. Therefore, it is possible to give the cards a story as a collection card, and various publication projects such as a three-dimensional insect encyclopedia, a three-dimensional plant encyclopedia, a three-dimensional tourist encyclopedia, or a three-dimensional manga can be made possible. The thickness of such a card case 1 can be 10 mm to 60 mm, including the thickness of the book cover 7. If it is less than 10 mm, the number of 3D collectible cards 200 is limited, and if it is more than 60 mm, the thickness of the book becomes too large, making it inconvenient to store.

[0026] As shown in Figures 2(a), 2(b), 3, and 4, the present invention has a simple and robust configuration of only the necessary components of the 3D observation device 300, and as a result of actual implementation, it has been possible to construct a very light structure weighing only 30g, which is less than one-third the weight of the existing 3D viewer device shown in Figure 7, which weighs 110g. This invention can be configured in the shape of a book, as shown in Figures 5(a), (b), and (c), and can be separated into a card case 1 for storing the 3D collection card 200 and a 3D device case 3 for storing the 3D observation device 300, and configured as separate book units. The book case 100 is composed of the card case 1 in Figure 5(a) and the folding surface 5 of the three-dimensional device case 3 or the book cover 7 as in Figure 5(b), and is composed of a coupling device 6, 6a on one side of the book cover 7, which is composed of a magnet, a magnetic material, etc. In addition, such a coupling device can cover or open the book cover 7, 7a as shown in Figures 5(a) and 5(b), and such a coupling device 6a can be configured with other known structures.

[0027] In the present invention, as shown in FIG. 6(a), the structure of the card case 1 and the structure of the three-dimensional device case 3 are configured in the upper and lower parts of the inside of the book case 100 in a single book structure. That is, as shown in FIG. 5(a), the three-dimensional collection card 200 is housed in a separate card case 1, and a separate book case 100 is configured. That is, as shown in FIG. 5(b), the three-dimensional observation device 300 is housed in a separate three-dimensional observation device case 3, and is configured in a separate book case 100.

[0028] As shown in FIG. 5(c), the structures of FIG. 5(a) and FIG. 5(b) are combined into one book case 100 by means of connecting devices 6, 6a. Since the card case 1 and the 3D device case 3 are separated, a user who owns the 3D device case 3 can continuously collect the 3D collection cards 200 of the card case 1 in a series as needed. The book covers 7, 7a of 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 store the 3D collection card 200, which has a width x height of 140 x 90 mm, the size of the card case 1 and the 3D device case 3 are set to 150 mm x 120 mm and 20-60 mm thick, so that the 3D collection card 200 and the 3D observation device 300 can be stored. The size of such a book-shaped card case 1 and a three-dimensional device case 3 can be applied to the Chinese version of publications (A5 sheets) of 210 x 148 mm, and the thickness of the book is 20-60 mm, so the present invention can also be applied to the 4.6 version (B6) of printed matter of 182 x 128 mm. By the same logic, a book case 100 of 240 x 150 mm size as shown in Figures 6(a) and 6(b) can be adapted to a size of up to 257 mm x 182 mm, which is the A4 size of printed matter, and can be published as a publication. When the handle 14 of the stereoscopic observation device 300 is configured in a form that can be combined and separated, it can be applied to various book sizes.

[0030] The above numerical values ​​are merely examples, and the same logic will be applied when new sizes or standards of 3D collectible cards are released. The present invention is similarly applicable when the book cover 7, 7a is made of transparent plastic. Furthermore, the numerical values ​​presented in the present invention are not limiting and may be varied within the logic of the present invention as presented for the convenience of explanation.

[0031] Therefore, the present invention's 3D observation device 300, which is composed of a thin barrier membrane 15, a fixing device 17 with an elastic device attached, and left and right lens plates 19, 21, has a mechanically strong structure and is simply constructed with a minimum volume barrier membrane 15, so that the weight is reduced to one-third of the weight of existing 3D observation devices, and children and the elderly can easily use it with one hand by using the handle. In addition, the stereoscopic image of the present invention provided by the printed material attached to the stereoscopic observation device 300 as shown in Figures 1(a) and 1(b) and 3 can be observed as a clear image using the surrounding external light without the need for a self-light source or a transmitted light source, and unlike a film structure, can be mass-produced in printed form. Furthermore, as shown in Figure 4, in the present invention, the front-to-back length b of the blocking film 15 and the focal length c of the left and right lenses 20, 22 are configured to be the same. When the left and right lenses 20, 22 are unfolded, the focal lengths of the left and right lenses 20, 22 automatically match the position of the 3D collection card 200, making it easy to observe a 3D image. In addition, as shown in Figure 5(a), a number of 3D cards 200 and a 3D observation device 300 can be combined into a separate book case 100 as a product unit, as shown in Figure 5(b), or by combining the 3D cards 200 and the 3D observation device 300 into a single book case 100 as shown in Figures 6(a) and 6(b), the product unit can be a book. In addition, the present invention is 30 times larger than the conventional film wheel type stereoscopic viewing device, so the viewing angle effect is more than 30 times larger, and this viewing angle effect is very effective when used for educational purposes.
