Description

  The present invention relates to a viewer for performing a stereoscopic view using at least two images representing the same subject at different angles.

  Conventionally, viewers for stereoscopically viewing images representing the same subject with different angles have been proposed. In other words, humans recognize objects as solids because they are seeing them with their left and right eyes at different angles, and in this way, the same angle is set to the same angle as the parallax between human eyes. If at least two images represented by changing the angle of the subject are presented separately to the left and right eyes, the images of both eyes can be perceived and synthesized simultaneously in the brain, so that a three-dimensional sensation can be obtained. It is.

Here, at least two images representing the same subject used for stereoscopic viewing at different angles (hereinafter referred to as at least two images representing the same subject at different angles and “image”). The transmission article and the reflection article are roughly classified. The main transmissive article is a film, that is, a photographic image developed positively, and the main reflective article is a photographic negative developed or conceptually driven visible information printed on paper or the like. Examples include printed materials. In addition, as the image is divided into a reflective article and a transmissive article, the viewer is divided into a reflective article and a transmissive article. Because, when stereoscopically viewing the transmissive article, it will be difficult to see the three-dimensional unless the light is transmitted through the transmissive article, so that the reflected light does not enter from other than the image bulletin board and the lens. However, when the reflective article is stereoscopically viewed, the reflected light can be seen three-dimensionally so that the reflected light can enter from other than the image display unit and the lens. This is because it must be configured to enter.
However, in this case, when both the reflective article and the transmissive article are to be stereoscopically viewed, each viewer has to be used, and thus there is a problem that the usability is poor.

Furthermore, since conventional viewers that stereoscopically view transparent articles are box-shaped made of metal or plastic, there are booklets (for example, books, books, magazines, brochures, catalogs, booklets, etc.) as supplements. (It is not limited.)) It was difficult to attach to. To be attached to a booklet, it can be developed into a single sheet and must be ready to be assembled. In addition, since it is made of metal or plastic, the manufacturing cost has been increased. Therefore, there has been a demand for a stereo viewer that can be assembled inexpensively and can be stereoscopically viewed in both the reflective article and the transmissive article.
Japanese Patent Application No. 7-281127

  The present invention has been made in order to solve the above problems, and the problem is to present a viewer that has a simple structure and can stereoscopically view both the transmissive article and the reflective article. To do.

  In order to solve the above-mentioned problem, claim 1 of the present invention presents a lens substrate provided with at least two lenses, and at least two images that face the lens substrate and represent the same subject from different viewpoints, at least An image bulletin board having one image bulletin board, an image fixing part for fixing an image for posting an image on the image bulletin board, a lower side of the lens board, and a table connected via a lens substrate lower mountain fold line part The lower support substrate, the side of the front and lower support substrate facing the lens substrate lower mountain fold line portion, and the lower support mountain fold line portion protruding downward, and connected to the lower side of the image display substrate, and the image On the lens substrate, a lower back support substrate connected via the posting substrate lower fold line portion, an upper side of the lens substrate, an upper support substrate connected via the lens substrate upper fold line portion, and the upper support substrate A back support substrate connected via a side facing the fold line portion, an upper protruding mountain fold line portion protruding upward, and connected via an upper side fold line portion of the image posting substrate; A right side of the lens substrate, a front right support substrate connected via a lens substrate right mountain fold line portion, a side of the front right support substrate facing the lens substrate right mountain fold line portion, and a mountain fold And through the right turn curve part that can be bent in a valley fold, and the right side of the image posting board, the back right support board connected through the image posting board right mountain fold line part, the front right support board, A right-turned portion provided over the right-turn curve portion and the back right support substrate, the maximum length in the longitudinal direction being equal to or greater than the diameter of the lens, and the maximum length in the lateral direction being equal to or greater than the diameter of the lens; The left side of the lens substrate and the lens substrate left mountain fold line are connected A front left support substrate, a side of the front left support substrate that faces the lens substrate left mountain fold line portion, and a back left support substrate that is connected via a left turn curve portion that can be bent into a mountain fold and a valley fold. The maximum length in the vertical direction is equal to or greater than the diameter of the lens, and the maximum length in the horizontal direction is equal to or greater than the diameter of the lens. A left window portion, a lighting window portion provided on the back support substrate, which can be freely opened and closed, the image display substrate, the front support substrate, the back support substrate, the top support substrate, the back support substrate, the front support substrate, A viewer comprising: a right support substrate, a back right support substrate, a front left support substrate, and an absorption layer that is provided inside each of the back left support substrate and absorbs light.

  In the invention of claim 1 of the present application, a front right support substrate, a back right support substrate connected to the front right support substrate via a bendable right turn curve portion, a right window portion, a front left support substrate, Since it has a back left support substrate, a left window portion, a daylighting window portion, and an absorption layer, which are connected to the front left support substrate via a bendable left turn curve portion, the reflective article is stereoscopically viewed. When doing this, it is possible to make a mountain fold, and when viewing the transmission article stereoscopically, by folding it in a valley fold, both the transmission article and the reflection article can be stereoscopically viewed with a single viewer.

  That is, when stereoscopically viewing the reflective article, the reflected light must be applied to the reflective article. In the present invention, since the right-turn curve portion and the left-turn curve portion can be folded into mountain folds, the reflective article can be easily stereoscopically viewed. In other words, by folding the right-turn curve portion and the left-turn curve portion into mountain folds, the lower support substrate, the back lower support substrate, the upper support substrate, the back upper support substrate, the front right support substrate, the back right support substrate, the front left support Each of the substrate and the back left support substrate protrudes outward, and as a result, between the upper side of the front right support substrate and the right side of the front support substrate, the upper side of the back right support substrate and the back upper support Between the right side of the substrate, between the lower side of the front right support substrate and the right side of the front support substrate, between the lower side of the back right support substrate and the right side of the back support substrate, and the upper side and top of the front left support substrate Between the left side of the support substrate, between the upper side of the back left support substrate and the left side of the back support substrate, between the lower side of the front left support substrate and the left side of the front support substrate, and the lower side of the front left support substrate And the left side of the back support substrate (hereinafter, between the top side of the front right support substrate and the right side of the top support substrate, the top side of the back right support substrate and the back top support plate). Between the right side of the substrate, between the lower side of the front right support substrate and the right side of the front support substrate, between the lower side of the back right support substrate and the right side of the back support substrate, and the upper side and top of the front left support substrate Between the left side of the support substrate, between the upper side of the back left support substrate and the left side of the back support substrate, between the lower side of the front left support substrate and the left side of the front support substrate, and the lower side of the front left support substrate And the left side of the lower support substrate are called “between the support substrates”), and reflected light can be taken in from this. It is possible to apply reflected light to the existing image, and the reflective article can be stereoscopically viewed.

  In the viewer according to the present invention, the right-turn curve portion and the left-turn curve portion are folded into mountain folds, so that reflected light can be further taken into the viewer. Even if the right-turn curve portion and the left-turn curve portion are valley-folded, a gap is formed between the support substrates. However, the size of the gap formed when the right-turn curve portion and the left-turn curve portion are valley-folded is smaller than the size of the gap formed when the right-turn curve portion and the left-turn curve portion are mountain-folded. Then, it becomes difficult for reflected light to enter, and it becomes difficult to stereoscopically view the reflective article. Furthermore, if the right turn curve part and the left turn curve part are valley-folded, the reflected light may be blocked by the front right support substrate, the back right support substrate, the front left support substrate, and the back left support substrate. Conceivable. In general, when viewing stereoscopically using a viewer, the viewer often has left and right viewers, so if the right-turn curve part and the left-turn curve part are valley-folded, it can be formed between the support substrates by the hand holding the viewer. It is also conceivable that the gap is closed and the reflected light is blocked. That is, if the right turn curve part and the left turn curve part are valley-folded, the front right support substrate, the back right support substrate, the front left support substrate, and the back left support substrate are directed to the inside of the viewer, so that the viewer is provided. In this case, hold the lens substrate right mountain fold line near the lens substrate side and the lens substrate left mountain fold line part near the lens substrate side with the thumbs of the left and right hands, respectively. Hold the viewer by holding the vicinity of the board side and the vicinity of the image bulletin board side of the image bulletin board left mountain fold line with one of the fingers other than the thumbs of the left and right hands. This closes the gap and blocks the reflected light from entering the viewer. Eventually, if the right-turn curve portion and the left-turn curve portion are folded into a valley fold, the reflected light does not enter sufficiently for the reasons described above, and it becomes difficult to stereoscopically view the three-dimensional article. However, if the right turn curve part and the left turn curve part are mountain-folded, the front right support board, the back right support board, the front left support board, and the back left support board face outward, so the front right By having a support substrate, back right support substrate, front left support substrate, and back left support substrate, it becomes possible to prevent the gap formed between the support substrates from being blocked with palms or fingers, and to reflect light. It becomes possible to incorporate it sufficiently inside the viewer. That is, by folding the right-turn curve portion and the left-turn curve portion into mountain folds, the front right support substrate, the back right support substrate, the front left support substrate, and the back left support substrate face the outside of the viewer. Hold with the thumb of the right hand, hold the front left support board with the thumb of the left hand, hold the back right support board with a finger other than the thumb holding at least the front right support board, and hold the back left support board with at least the thumb holding the front left support board If the finger is pressed, it becomes possible to have a viewer without closing the gap with a finger or palm, so that reflected light can be taken in more and the reflected article can be more stereoscopically viewed. In addition, since the viewer of the present invention can fold the right-turn curve portion and the left-turn curve portion into mountain folds, the lens substrate and the image display substrate can be brought closer to or away from each other, and focusing is easily performed. It becomes possible.

  In addition, depending on the size of the front support substrate, the back support substrate, the front support substrate, the back support substrate, the front right support substrate, the back right support substrate, the front left support substrate, and the back left support substrate, The gap formed between the support substrates is reduced, and as a result, it may be difficult to sufficiently take in reflected light. For example, if you want to provide a viewer for children, you can hold it with your child's hand, and it is necessary to make it so that it can be stereoscopically viewed, so the front right support substrate, the back right support substrate, the front left As the support substrate, the back left support substrate, the front support substrate, the back support substrate, the front support substrate, and the back support substrate are reduced, the gap formed between the support substrates is also reduced. It may be difficult to take in enough reflected light. However, in the present invention, because the back support substrate is provided with an openable and closable lighting window portion, if the reflected light is not sufficient only by the gap formed between the support substrates, the lighting window portion is opened. Since the reflected light can be sufficiently taken in, the reflective article can be easily stereoscopically viewed.

  Furthermore, since the viewer of the present invention is provided with the daylighting window portion on the back support substrate, the reflected light can be more taken into the viewer. That is, when the daylighting window part is provided on the front support substrate, even if the daylighting window part is open, the human forehead hits the daylighting window part, and the reflected light is blocked by the human head. This is also the case. However, since the viewer according to claim 1 of the present invention has the daylighting window portion provided on the back support substrate, it is possible to prevent the reflected light from being blocked by the human head, and the reflected light can be further reduced. It becomes possible to incorporate it into the viewer.

  Further, when viewing the transmissive article in three dimensions, it is necessary to block the reflected light because the transmitted light must be applied to the transmissive article. In the viewer of the present invention, the right-turn curve portion and the left-turn curve portion can be flattened so as not to be bent, or the right-turn curve portion and the left-turn curve portion can be folded into a valley fold, so that the reflected light is blocked. Thus, the transmission article can be viewed stereoscopically.

That is, when stereoscopically viewing the transmission article, without bending the right-turn curve portion and the left-turn curve portion, the lower support substrate, the back lower support substrate, the upper support substrate, the back upper support substrate, the front right support substrate, By flattening the back right support substrate, the front left support substrate, and the back left support substrate, it becomes possible to prevent the viewer from becoming a substantially cylindrical shape and forming a gap between the support substrates. Therefore, it becomes possible to block the reflected light from entering the viewer, and the transmission article can be stereoscopically viewed. Of course, since the support substrates are not connected, depending on how the viewer is held, a gap may be formed between the support substrates and reflected light may enter. Therefore, for example, each substrate may be fixed with a tape or the like so that no gap is formed between the support substrates, and further, the upper support substrate, the back support substrate, the lower support substrate, and The front right support substrate and the back right support substrate are sandwiched in the vicinity of the right side of each of the bottom back support substrate, and the left side of each of the top support substrate, the back top support substrate, the front bottom support substrate, and the back bottom support substrate The front left support substrate and the back left support substrate may be sandwiched in the vicinity. In addition, when pinching, it is good to fix an upper protrusion mountain fold line part and a lower protrusion mountain fold line part.
It should be noted that if the right-turn curve portion and the left-turn curve portion are flattened so as not to be bent, there may be a case where the focus is not achieved and stereoscopic viewing is impossible. However, since the viewer of the present invention can fold the right-turn curve portion and the left-turn curve portion into a valley fold, by folding the right-turn curve portion and the left-turn curve portion into a valley fold, the upper protruding mountain fold line portion and the lower protrusion Since the mountain fold line portion is also mountain-folded, the lens substrate and the image display substrate can be brought close to or away from each other, and the focus can be easily adjusted. Note that when the right-turn curve portion and the left-turn curve portion are folded into valleys, a gap is formed between the support substrates, and thus reflected light enters the viewer. However, in the present invention, as described above, when it is folded in a valley, it is possible to form a small gap formed between the support substrates, and the front right support substrate, back right support substrate, front left support Since the substrate and the back left supporting substrate enter the viewer and play a role of blocking the reflected light, it is not difficult to stereoscopically view the transmissive article. Furthermore, when viewing stereoscopically using a viewer, there are many cases where the viewer has left and right viewers. Therefore, when the right and left turn curve portions are folded into valley folds, the lens substrate right mountain fold line vicinity in the lens substrate Hold with the thumb of the right hand, hold the lens board near the left fold line in the lens board with the thumb of the left hand, and press the area around the image fold board right fold line in the image display board with any finger other than the thumb of the right hand. In order to have a viewer by pressing the left side of the left side of the image display board in the image display board with a finger other than the thumb of the left hand, the gap formed between the support board with the palm or fingers It becomes possible to block, and more reflected light can be prevented from entering the viewer. When stereoscopically viewing the transmission article, it is necessary to close the daylighting window provided on the back substrate.

  Note that any method can be employed for opening and closing the daylighting window. For example, the daylighting window part is composed of a window part obtained by punching the back support substrate into an arbitrary shape and a lid part that covers the window part, and when the reflective article is stereoscopically viewed, the lid part is removed. When the reflected light enters the viewer and the transmission article is stereoscopically viewed, the window portion may be covered with a lid portion to block the reflected light. For example, you may provide so that the arbitrary sides of a lighting window part may be connected with a back support substrate. When connecting the back support board and the daylighting window part, it is possible to open the daylighting window part by folding the lighting window part folding part which is the part connecting to the back support board in the daylighting window part. It is possible to close the daylighting window part by not folding the folding window part of the daylighting window part or making a valley fold. In the case of providing an arbitrary side of the daylighting window portion so as to be connected to the back support substrate, it is possible to select an arbitrary direction as to which direction it can be opened and closed. For example, it may be right-opening or left-opening. However, in the present invention, when stereoscopically viewing the transmission article, it is necessary to close the daylighting window portion. This is preferable because it can be closed not only easily but also difficult to open. It should be noted that a locking means capable of locking the daylighting window part to the daylighting window part or the back support substrate so that the daylighting window part can be kept open and closed. Although it is preferable to provide, it does not necessarily limit to this.

  Further, in the present invention, an image display substrate, a front and lower support substrate, a back and bottom support substrate, a top and bottom support substrate, a back and top support substrate, a front and right support substrate, a back and right support substrate, a front and left support substrate, and a back and left support Absorbing layer that absorbs light is provided inside each substrate, so that even if reflected light enters inside the viewer by forming a gap between the support substrates by making a valley fold, it absorbs light The transmission article can be stereoscopically viewed. In other words, when viewing the transmission article with the right-turn curve portion and the left-turn curve portion as a valley fold, for example, when the surrounding environment is very bright, strong reflected light enters the viewer, resulting in transmission. There may be a case where stereoscopic viewing of the article becomes difficult. However, the viewer of the present invention includes an image display substrate, a lower support substrate, a back lower support substrate, a front support substrate, a back support substrate, a front right support substrate, a back right support substrate, a front left support substrate, and a back support substrate. Since an absorption layer that absorbs light is provided inside each substrate of the left support substrate, even if the right-turn curve portion and the left-turn curve portion are valley-folded, even if reflected light enters the viewer, the absorption layer Since the reflected light is absorbed, the transmissive article can be stereoscopically viewed. In addition, although it is preferable to provide an absorption layer also on the inner surface of the lens substrate, it may not be provided.

  Here, the absorbing layer may be any layer as long as it can absorb reflected light. In general, the darker the color, the easier it is to absorb light. Therefore, a dark color such as strawberry, purple, or dark brown is preferable, and a black color is more preferable. In addition, an arbitrary method can be adopted for providing the absorption layer. For example, paper coated in black may be pasted, or black paint may be provided by a printing method. When an absorption layer is provided by a printing method, a known printing method such as offset printing, gravure printing, or screen printing can be adopted. Generally, gravure printing or waterless offset printing is more suitable for ink. Since it is possible to increase the density, it becomes possible to print the paint more darkly.

  Note that if the right turn curve part and the left turn curve part are valley-folded, the front right support board, the back right support board, the front left support board, and the back left support board enter the inside of the viewer. And at least the right side or the left side of the image to be stereoscopically viewed is hidden by the front right support substrate, the back right support substrate, the front left support substrate, and the back left support substrate. It may be necessary to limit the size of. However, in the present invention, since it has a right window portion and a left window portion, the front right support substrate, the back right support substrate, the front left support substrate, and the back left support substrate may become an obstacle when stereoscopically viewing. It becomes possible to prevent. That is, in the viewer of the present invention, since it has a right window portion and a left window portion, by turning the right turn curve portion and the left turn curve portion into a valley fold, the front right support substrate, the back right support substrate, the front left support substrate, And even if the back left support board enters the viewer and blocks the field of view, it is possible to see the left and right of the image to be viewed stereoscopically from the right window part and the left window part. It is possible to prevent the substrate, the front left support substrate, and the back left support substrate from becoming obstacles when stereoscopically viewed. As a result, it is not necessary to limit the size of the image, and an image having an arbitrary shape can be stereoscopically viewed. Therefore, it is possible to provide a viewer that can make the user more interesting. .

  In addition, the size of the right and left windows is such that the maximum length in the vertical direction is greater than or equal to the diameter of the lens, and the maximum length in the horizontal direction is greater than or equal to the diameter of the lens. The front right support substrate, the back right support substrate, the front left support substrate, and the back left support substrate are not obstructed. The vertical lengths of the right window portion and the left window portion are the height direction when the front and lower support substrates and the back lower support substrate are placed downward, that is, the horizontal length, and the horizontal length. The length in the direction is the length in the horizontal direction when the lower and upper support substrates are placed face down, that is, the length in the direction perpendicular to the length in the vertical direction. When the right and left turn curves are valley-folded, it is most likely that the field of view is blocked when looking at the lens from the point where the approximate center of each pupil is located toward the image display board. The point where the drawn horizontal line intersects the right-turn curve part and the left-turn curve part (hereinafter, the point where the horizontal line drawn from the center of the lens substrate toward the image display board intersects the right-turn curve part is called the “right obstacle point”, and , The point where the horizontal line drawn from the center of the lens substrate toward the image display board intersects with the left turn curve portion is referred to as the “left obstacle point”), and its vicinity, so this right obstacle point, left obstacle point, And it is preferable to provide each of the right window part and the left window part so that the vicinity does not become an obstacle when the valley is folded, specifically, the longest part of each window part in the longitudinal direction The intersection of the longest parts in the horizontal direction is on the right Located in the vicinity of the fault point and the left point of failure, and the longest portion in the longitudinal direction is preferably provided so as to be located respectively on the left curved portion and turn right curved portion. However, the present invention is not limited to this.

  The right window part and the left window part are arbitrary on the front right support board, the right turn curve part and the back right support board, and over the front left support board, the left turn curve part and the back left support board, respectively. It is possible to provide it in a shape, but if it is provided so that each side of the right window part and the left window part is substantially coincident when the right turn curve part and the left turn curve part are valley-folded, the beauty when stereoscopically viewing Can be improved, which is preferable. In other words, a part of the right window part provided on the front right table right support board and a part of the right window part provided on the back right support board are substantially matched when the right turn curve part is valley-folded, If a part of the left window part provided on the front left support substrate and a part of the left window part provided on the back left support substrate are substantially coincided when the left turn curve part is folded, a stereoscopic view is obtained. It is possible to improve the beauty of the occasion. For example, when the front right support substrate, the back right support substrate, the front left support substrate, and the back left support substrate have the same size, the right window portion is bilaterally symmetrical with the right turn curve portion as the center. Thus, it is possible to improve the aesthetics when viewing stereoscopically because the sides are approximately the same when the valley is folded when the front right support substrate, the right turn curve part and the back right support substrate are provided. Become. Similarly, the left window part has a left turn curve part as its center, and it is symmetrical to the left and right support boards, the left turn curve part and the back left support board. Since the sides substantially coincide with each other, it is possible to improve the aesthetics when stereoscopic viewing.

Further, since the viewer of the present invention has a simple structure, it can be easily assembled and attached to a booklet. The front right support substrate, the back right support substrate, the front left support substrate, and the back left support substrate can be made of any material as long as they can be folded and folded. It is preferable to form by. Furthermore, the lens substrate, the image display substrate, the image fixing unit, the front and lower support substrate, the back and bottom support substrate, the top and bottom support substrate, and the back and top support substrate can adopt any material, but paper If it is formed, it is possible to reduce the manufacturing cost, which is preferable. That is, a paper lens substrate, a paper lens substrate, a paper image display substrate, a paper image fixing portion, a paper bottom support substrate, a paper back bottom support substrate, a paper top support Easily by making a substrate, a paper front and lower support substrate, a paper front right support substrate, a paper back right support substrate, a paper front left support substrate, and a paper back left support substrate It is possible to provide a viewer that can be assembled and can reduce manufacturing costs, and can be attached to a booklet as an appendix. Also, if the front right support substrate, back right support substrate, front left support substrate, and back left support substrate are formed of paper, the left turn curve will be worn by the flexibility of the paper, and the front left support side and the back left support side Can be prevented, and the right-turn curve portion can be prevented from being worn and the front right support side and the back right support side can be separated. That is, the viewer of the present invention performs the right turn curve portion and the left turn curve portion in a mountain fold when stereoscopically viewing the reflective article, and the right turn curve portion and the left turn curve portion when the transparent article is stereoscopically viewed. Because it is necessary to fold the right and left turn curves from a mountain fold to a valley fold, or from a valley fold to a mountain fold, the right turn curve and the left turn curve are easy to wear. is there. Therefore, as a result of repeated folding, the left turn curve part was worn and the front left support side and the back left support side were separated, and the undefined folding part was worn and the front right support side It is conceivable that the back right support side is separated. However, if the front right support substrate, the back right support substrate, the front left support substrate, and the back left support substrate are formed of paper, the flexibility of the paper minimizes the wear of the right turn curve portion and the left turn curve portion. It is possible to prevent the support sides from being separated. After all, if the viewer of the present invention is made of paper, it can be easily attached to a booklet, and further, a viewer capable of minimizing the deterioration of the right turn curve portion and the left turn curve portion is provided. Is possible.
When the viewer is formed of paper, for example, any paper such as art paper or coated paper can be used. However, it is preferable to use elastic paper because the viewer is fixed. . For example, if it is art paper, if the continuous amount is 180 g / mm or more, it is preferable because of elasticity, and if it is coated paper, it is elastic if the continuous amount is 180 g / mm or more. preferable. Note that it is not necessary to limit to art paper or coated paper, and any type of paper can be used, and any continuous amount of paper can be used. In addition, when attaching the developed version of the viewer of the present invention to a booklet, it is attached to any booklet regardless of how it is bound by setting its thickness to 3 mm or less, further 2 mm to 3 mm. It is preferable because it becomes possible.

  In addition, at least two lenses are required on the lens substrate. This is because stereoscopic vision is performed using the illusion of the right eye and the left eye, and is caused by the need for a right eye lens and a left eye lens. Here, when forming the lens substrate, rather than providing at least two lenses directly on the substrate, the lens is fixed to the lens outer fixing portion that is attached to the outer periphery of the lens to fix the lens, and the lens is fixed. In addition, when the lens substrate is formed by providing the lens outer fixing portion on the substrate, it becomes possible to form a lens substrate that can surely achieve stereoscopic viewing at a reduced cost. That is, in order to realize stereoscopic viewing, the lens substrate must be formed so that the center of the right-eye lens where the right eye is located and the center of the left-eye lens where the left eye is located are horizontal. However, when the lens for the right eye and the lens for the left eye are directly provided on the substrate, a high level of technology is required to form the lens substrate so that the center of each lens is horizontal, so that the manufacturing efficiency is lowered. In addition, there is a problem that the manufacturing cost is increased. This problem is particularly noticeable when paper is used for the substrate. In other words, because paper is easily distorted, forming the lens substrate so that the center of the lens for the right eye and the lens for the left eye is horizontal requires very advanced technology, resulting in lower manufacturing efficiency. The manufacturing cost has increased. Therefore, if the lens is fixed to the lens outer fixing part that is attached to the outer periphery of the lens to fix the lens, and the lens substrate is shaped so that the lens outer fixing part to which the lens is fixed is provided on the substrate, the lens outer fixing is performed. The lens is fixed so that the center of the lens for the right eye and the center of the lens for the left eye are substantially horizontal by the lens outer fixing part, so that the lens substrate is not required for advanced technology. Thus, it becomes possible to improve the manufacturing efficiency, so that it becomes possible to manufacture the lens substrate without incurring manufacturing costs. It is preferable that the lens outer fixing portion is formed together when forming the lens, so that the center of the right eye lens and the center of the left eye lens can be made more horizontal. Here, forming together means that the lens and the respective molds forming the lens outer fixing portion are integrated, and a state in which the lens is provided on the lens outer fixing portion is formed by a single pouring. . By doing so, it is possible to make the center of the lens for the right eye and the center of the lens for the left eye more horizontal. Furthermore, since the process of fixing the lens to the lens outer fixing portion can be reduced, the number of times the lens is touched can be reduced, and the lens can be prevented from being damaged. In addition, since it is possible to reduce the process of providing a lens on the lens outer fixing portion, it is possible to reduce the manufacturing cost. In forming the lens, a known material can be used. Also, the lens outer fixing portion can be formed using a known material as long as the lens can be fixed.

Also, the main transmissive article is a film, that is, a photographic image developed positively, and the main reflective article is a photographic image developed negative or printed on paper or the like. Printed materials. In addition, when a printed matter is used for the reflective article, the number of lines of the halftone screen is 500 or more per inch, more preferably 750 or more so that the halftone dots cannot be seen when magnified by the lens. Although it is preferable to use a high-density thing, it is not necessarily limited to this. In addition, when the reflective article is formed by a printing method, any printing method can be adopted, for example, gravure printing, offset printing, or the like. Note that the stereoscopic image may have any shape as long as stereoscopic vision is possible. In general, an image at the time of stereoscopic viewing is often expressed in a rectangle such as a square or a rectangle, but can be expressed in an arbitrary shape such as a heart shape or a circle.
Further, according to a second aspect of the present invention, the lens substrate includes a lens support substrate provided with at least two lenses, and a lens forming substrate attached to the lens support substrate and provided with at least one lens hole. The viewer according to claim 1, wherein:

  That is, according to the second aspect of the present invention, since the lens substrate includes the lens support substrate and the lens forming substrate, the lens can be further fixed, and the lens substrate can be further strengthened. Therefore, it is possible to prevent the lens substrate from being deformed by the pressure applied to the lens substrate when the right-turn curve portion and the left-turn curve portion are folded into a mountain fold and a valley fold, or a force that suppresses the viewer when stereoscopically viewing. It becomes possible. That is, when the lens substrate is a single substrate, which is a form included in claim 1, the lens substrate supports and fixes the lens, and is connected to other substrates on the upper, lower, left and right sides. In addition, since it plays two roles of configuring the viewer, it may be impossible to withstand the weight of the lens. For example, the thicker the lens, the easier it is to process, so the lens often becomes thicker when trying to increase the working efficiency. However, when the lens is heated, the lens becomes heavier, and as a result, the lens substrate cannot withstand the weight of the lens, and the lens may be detached from the lens substrate when the viewer is used. However, in the viewer according to claim 2 of the present invention, since the lens substrate is a lens supporting substrate and a lens forming substrate that are adhered to each other, the lens supporting substrate plays a role of supporting and fixing the lens, and forming the lens. Since the board plays the role of connecting the other boards on the top, bottom, left, and right sides to form the viewer, it is possible to fix the lens more, and no matter what size lens is used, the lens It becomes possible to prevent from taking off.

  Further, in the invention according to claim 2 of the present application, since the lens support substrate and the lens forming substrate are attached to each other and their roles are separated, the lens substrate can be made stronger. Become.

  That is, when the lens substrate is a single substrate, which is a form included in claim 1 of the present application, the lens substrate supports and fixes the lens, and is connected to other substrates on the upper, lower, left and right sides. Since the two roles of constituting the viewer are taken, there is a problem that the lens substrate may be bent during stereoscopic viewing depending on the lens to be provided. That is, the viewer of the present invention is a viewer capable of stereoscopically viewing both the reflection article and the transmission article, and the right turn curve portion and the left turn curve portion are folded into a mountain fold or a valley fold, and a lens substrate and an image are displayed. This is because the focus can be adjusted by bringing the substrate close to or away from the substrate. That is, the viewer of the present invention is a viewer capable of stereoscopically viewing both the reflective article and the transmissive article. When the reflective article is stereoscopically viewed, the right turn curve portion and the left turn curve portion are folded in a mountain fold. When stereoscopically viewing the transparent article, the right-turn curve portion and the left-turn curve portion are folded into a valley fold, so the right-turn curve portion and the left-turn curve portion are folded from a mountain fold to a valley fold, or from a valley fold to a mountain fold. Action is required. At this time, there is no problem if only the front right support substrate, the back right support substrate, the front left support substrate, and the back left support substrate are folded, but the lens substrate right mountain fold line portion and the lens substrate left mountain fold line portion It is also conceivable to fold back while holding the vicinity of. That is, the thumb of each hand holds the lens board right mountain fold line part and the lens board left mountain fold line part, respectively, and the image display board right mountain fold line part and the image bulletin board with any finger other than the thumb of each hand. After pressing the vicinity of the left mountain fold line, the right hand pulls the front right support board or back right support board, and the left hand pulls the front left support board or back left support board with the middle finger or index finger, respectively. It is conceivable that the right-turn curve portion and the left-turn curve portion that are folded in turn are folded back into mountain folds. Also, when turning the right and left curve sections folded in a mountain fold into a valley fold, press the right hand support board or back right support board with the middle finger or index finger with the right hand and the middle finger or index finger with the left hand. By pressing the left support substrate or the back left support substrate, it is conceivable that the right turn curve portion and the left turn curve portion folded in a mountain fold are folded back into a valley fold. As a result, the lens substrate may be bent.

  In addition, the viewer of the present invention has a lens substrate and an image display substrate by folding the right-turn curve portion and the left-turn curve portion into a mountain fold or a valley fold and simultaneously folding the upper protruding mountain fold line portion and the lower protruding mountain fold line portion into a mountain fold. Can be moved closer to or away from each other, and the focus can be adjusted. At this time, in order to bring the lens substrate and the image display substrate closer, hold the vicinity of the lens substrate side of the lens substrate right mountain fold line portion and the vicinity of the lens substrate side of the lens substrate left mountain fold line portion with the right and left thumbs, Hold the lens board in the vicinity of the image bulletin board side of the image bulletin board right mountain fold line part and the image bulletin board side of the image bulletin board left mountain folding line part with one of the fingers other than the right and left thumbs. It is necessary to push it closer to the image board. As a result, it is considered that pressure is applied to the lens substrate and the lens substrate is bent.

  If the lens substrate is bent, the center of the lens for the right eye where the right eye is located and the center of the lens for the left eye where the left eye is located will not be horizontal, making it difficult to focus and making stereoscopic viewing difficult. End up. However, in the invention according to claim 2 of the present application, since the lens support substrate and the lens forming substrate constituting the lens substrate are attached to each other and their roles are separated, the lens substrate is made stronger. It becomes possible to do. That is, the lens support substrate that constitutes the lens substrate plays a role of supporting and fixing the lens, and the lens forming substrate that constitutes the lens substrate is connected to other substrates at the upper, lower, left, and right sides to constitute a viewer. Therefore, the lens substrate can be made stronger. As a result, it is possible to prevent the lens substrate from being bent even when pressure is applied to the lens substrate when the right-turn curve portion and the left-turn curve portion are turned into a mountain or valley, or when focusing is performed.

  The size of the lens support substrate and the lens formation substrate can be arbitrarily set, but the size of the lens support substrate and the lens formation substrate is substantially the same as that of the lens support substrate or the lens formation substrate. Smaller than the substrate, the lens forming substrate lower fold line portion, the lens forming substrate upper fold line portion, the lens forming substrate right mountain fold line portion, and the lens forming substrate left mountain fold line portion can be easily folded into mountain folds. Therefore, it is preferable.

  Furthermore, if the lens support substrate and the lens forming substrate are approximately the same size, the above-described effects can be made more prominent. That is, if the lens support substrate and the lens forming substrate are made substantially the same size, the pressure due to having the lens substrate upper mountain fold line portion and the lens substrate lower mountain fold line portion of the lens substrate in the three-dimensional view is applied to the lens substrate. Even if it is applied, it is possible to further prevent the lens substrate from being bent. In other words, when using the viewer of the present invention, it is preferable to have the left and right of the viewer, but infants who can not support the viewer by holding the viewer for the first time or because the hand is small use the viewer In this case, the viewer may have a viewer with the upper and lower sides of the lens substrate. For example, as a result of holding the vicinity of the upper support substrate side of the lens substrate upper fold line portion and the vicinity of the lower support fold line portion of the lens substrate lower fold line portion with the index finger and thumb, respectively, the lens substrate is held vertically. Cases can be considered. In this case, if the lens substrate according to the first aspect of the present invention is a single lens substrate, the lens substrate is bent in the vertical direction because a force to push the lens substrate in the vertical direction works. Can be considered. However, if the lens substrate has a lens support substrate and a lens forming substrate that are attached to each other, and the lens support substrate and the lens forming substrate are substantially the same size, the lens substrate is sandwiched in the vertical direction. This makes it possible to prevent the lens substrate from being bent even when a force pushing the lens substrate in the vertical direction is applied. After all, the lens substrate is a lens support substrate provided with at least two lens substrates, and a lens forming substrate that is attached to the lens support substrate and is provided with at least one lens hole. By having it, it is possible to fix the lens more and to prevent the lens substrate from being bent no matter how the pressure is applied to the lens substrate.

  Here, the lens hole is a hole provided so that at least two lenses provided on the lens support substrate can be viewed. And at least one lens hole is sufficient. For example, the lens hole may be provided in an elliptical shape so that at least two lenses provided on the lens support substrate are located in one lens hole. For example, one lens is located in one lens hole. As described above, at least two lens holes may be provided in the lens forming substrate. The size of the lens hole provided in the lens forming substrate can be set to any size as long as it can be viewed stereoscopically by looking at at least two lenses provided on the lens support substrate. For example, in the case where at least two lens holes are provided at a position corresponding to the lens provided on the lens support substrate of the lens forming substrate, each lens hole may be substantially the same size as the lens, You may enlarge it. In addition, if it is possible to look through the lens and stereoscopically view it, the lens can be made smaller than the lens. For example, the lens may be a circle having a diameter of 3 cm, the lens hole provided in the lens forming substrate may be a circle having a diameter of 1 cm, and the lens center and the center of the lens hole may be attached to match each other. Further, the shape of the lens hole is not limited to a circle or an ellipse, and any shape can be adopted.

  Note that the lens support substrate and the lens forming substrate can be attached so that they can be easily peeled off. By attaching the lens support substrate and the lens forming substrate so that they can be easily peeled off, it becomes possible to protect only the lens substrate, so it is easier to protect the lens from scratches. It becomes possible to do. The lens supporting substrate and the lens forming substrate can be formed by using any desired one, but it is preferable to form the lens as described above.

  Further, according to the present invention, the right window part and the left window part are hexagonal shapes obtained by combining two trapezoids at the bottom base, and the bottom base is located at the right turn curve part and the left turn curve part, respectively. The viewer according to claim 1, wherein

  That is, according to the invention of claim 3 of the present application, the right window portion and the left window portion are hexagons obtained by combining two trapezoids at the lower base, respectively, and the lower base is formed into a right turn curve portion and a left turn curve portion. Since each is located, it is possible to form the right window and left window that can obtain a sufficient field of view with a minimum area, so that the reflected light enters the viewer from the right window and the left window. It is possible to further prevent entry, and the transmission article can be stereoscopically viewed more clearly.

  That is, when the right window part and the left window part having the length in the vertical direction and the length in the horizontal direction set to an arbitrary length equal to or larger than the diameter of the lens are included in the first aspect of the present invention. It is possible to prevent the view from being blocked by making the right turn curve part and the left turn curve part into a valley fold, but the right window part and the left window part are large because the right window part and the left window part are large. Therefore, the reflected light may enter the viewer, making it difficult to view the transmission article beautifully and stereoscopically. The viewer according to claim 3 of the present application is provided such that the right window portion and the left window portion are hexagons each having two trapezoids at the lower base, and the lower base is located at the right turn curve portion and the left turn curve portion, respectively. Therefore, it becomes possible to make the right window part and the left window part have the smallest area without obstructing the view, and it is possible to further prevent the reflected light from entering the viewer from the right window part and the left window part. It becomes possible.

  The hexagons of the right window and left window are two trapezoids combined at the lower base, but the upper base of each of the two trapezoids is the back of the front right support substrate on the right window side. It is located on the right support substrate, and on the left window portion side, it is located on the front left support substrate and the back left support substrate. The height of each trapezoid is not less than the radius of the lens, and the length of the lower base is not less than the diameter of the lens. After all, in the invention according to claim 3, the upper base forms the maximum in the vertical direction of the right window portion and the left window portion, and the front right support substrate, the back right support substrate, the front left support substrate, and the back left The support substrate plays a role of solving the problem of hiding at least the right side or the left side of the image, and the lower base plays a role of minimizing the areas of the right window portion and the left window portion. As a result, it is possible to minimize the right and left window areas without obstructing the field of view, and to prevent the reflected light from entering the viewer from the right and left window areas. Is possible. Note that the trapezoids provided on the respective substrates do not have to be bilaterally symmetric, and may be asymmetric depending on the shape of the stereoscopically viewed image and the purpose of use of the viewer. Moreover, what connects an upper base and a lower base does not need to be a straight line, respectively, and can be made into arbitrary shapes according to the shape of the image to be viewed stereoscopically and the purpose of use of the viewer. For example, a curved line such as an arc or a free curve may be used, or a broken line may be used. Eventually, in claim 3 of the present invention, the trapezoid forms the maximum of the vertical length of the right window portion and the left window portion, and the front right support substrate, the back right support substrate, the front left support substrate, and , An upper base that plays the role of solving the problem that the back left support substrate hides at least the right side or the left side of the image, and a lower base that plays a role of minimizing the area of the right window part and the left window part As long as there is a portion corresponding to, any of them may be used. For example, the upper base and the lower base may not be parallel, and the portions corresponding to the upper base and the lower base may be curved. The trapezoidal shape provided on the front right support substrate, back right support substrate, front left support substrate, and back left support substrate is arbitrary for each substrate depending on the shape of the image to be stereoscopically viewed and the purpose of use of the viewer. It is possible to make this shape. For example, a trapezoid having a different shape may be provided on each substrate, or a trapezoid having the same shape may be provided on all the substrates. When it is desired to make the appearance beautiful, the trapezoids provided on the front left support substrate and the front left support substrate are preferably the same shape, and the trapezoids provided on the back left support substrate and the back left support substrate are preferably the same shape, Furthermore, it is more preferable that the trapezoids provided on all the substrates have the same shape. If the height of each trapezoid is equal to or greater than the radius of the lens, it is possible to prevent the field of view from being blocked. The height of each trapezoid can be arbitrarily determined. For example, it is not necessary to make all the heights the same, but to make it higher is to incorporate reflected light into the viewer unnecessarily. Therefore, it is preferable that each height is the same. The trapezoidal height refers to the maximum value of the length of a line segment cut at a point where a straight line extending vertically from an arbitrary point on the lower base toward the upper base intersects the upper base.

  In addition, the present invention has a nasal window of a size capable of inserting a nose, provided over the lens substrate and the lower and upper support substrates at substantially the center of the lower fold line portion of the lens substrate. The viewer according to any one of claims 1 to 3.

Furthermore, since it becomes possible to put the nose into the nostril, it is possible to prevent the surface of the viewer from being soiled.

  In other words, because the nose head has a lot of oil, if the viewer is used many times and the head of the nose gets attached to the viewer many times, only the part with the head of the nose will be discolored. Appearance deteriorates. In the invention according to claim 4 of the present application, since a nostril for inserting the nose is provided and the nose can be inserted, the head of the nose can be in direct contact with the viewer. Can be prevented.

  In addition, a fifth aspect of the present invention is a booklet attached with the viewer according to any one of the first to fifth aspects.

A trapezoid 67 is provided such that its bottom is located at the right turn curve 24, and a back right support substrate side trapezoid 68 is provided on the back right support substrate 26, and a bottom right is located at the right turn curve 24. The support substrate side trapezoid 67 is provided so as to overlap the bottom base, and the front left support substrate 28 is provided with a front left support substrate side trapezoid 76 so that the bottom base is located at the left turn curve portion 29. On the support substrate 31, a back left support substrate side trapezoid 77 is provided so that its lower base overlaps with the lower base of the front left support substrate side trapezoid 76 located at the left turn curve portion 29. In addition, the length of each trapezoid lower base 69 located in the right turn curve portion 24 and the length of each trapezoid lower base 78 located in the left turn curve portion 29 are equal to or greater than the diameter of the lens, and the front right support substrate side. The height 72 of the trapezoid 67, the height 73 of the back right support substrate side trapezoid 68, the height 81 of the front left support substrate side trapezoid 76, and the height 82 of the back left support substrate side trapezoid 77 are each equal to or greater than the radius of the lens. Therefore, the field of view when the valley is folded is such that the right and left sides of the image 83 posted on the image posting unit 9 can be seen through the right window portion 32 and the left window portion 33 provided on the respective substrates. Yes. Further, the front right support substrate side trapezoid 67, the back right support substrate side trapezoid 68, the front left support substrate side trapezoid 76, and the back left support substrate side trapezoid 77 have the same shape, and the bottom bases thereof coincide. Therefore, when the right turn curve portion 24 and the left turn curve portion 29 are valley-folded, the sides of the front right support substrate side trapezoid 67 and the back right support substrate side trapezoid 68 substantially coincide with each other. Since the sides of the right support substrate side trapezoid 67 and the back right support substrate side trapezoid 68 substantially coincide with each other, the field of view is made beautiful. As shown in FIG. 7, even when the right window portion 32 and the left window portion 33 are provided, the image 83 posted on the image posting portion 9 on the upper portion and the lower portion of the right window portion 32 and the left window portion 33. In some cases, there is an image shielding portion 85 that hides the image, but generally, when viewing stereoscopically, the right eye that is the intersection of the horizontal line drawn from the center 37 of the right-eye lens 2 and the image display unit 9 is used. The focal point 86 of the left eye and the focal point 87 of the left eye, which is the intersection of the horizontal line drawn from the center 38 of the lens 3 for the left eye and the image posting unit 9, are the boundary for the right and left eyes of the image 83 posted on the image posting unit 9. Since the stereoscopic vision becomes possible by approaching the vicinity of the line 84, the image shielding portion 85 formed on the upper and lower portions of the right window portion 32 and the left window portion 33 can be viewed stereoscopically due to a shift in the angle between the right eye and the left eye. The image is distorted, or what is visible to the right eye but not the left eye is depressed Or, conversely, things that are visible to the left eye but not visible to the right eye may occur, and this is a part that causes obstacles in the stereoscopic image, so it is not the main part for stereoscopic viewing There are many cases. That is, in stereoscopic viewing, the right-eye image main portion 88 near the right-eye focal point 86 and the left-eye image main portion 89 near the left-eye focal point 876 are the most beautifully stereoscopic portions. Since the concealment portion 85 is often not a main portion for stereoscopic viewing, the right-eye image main portion 88 that is in the vicinity of the right-eye focus 86 and the left-eye image main portion 89 that is in the vicinity of the left-eye focus 87. Can be seen stereoscopically, and the image shielding portion 85 that hides the images present in the upper and lower portions of the right window portion 32 and the left window portion 33 has an effect on stereoscopic viewing. It is thought that there are few. After all, in the viewer 1 of the present invention, the right window portion 32 and the left window portion 33 each have a maximum in the vertical direction that is equal to or larger than the diameter of the lens. Since the main image portion 89 can be viewed, the user who uses the viewer 1 can perform stereoscopic viewing without giving a sense of discomfort or discomfort. The right window portion 32 and the left window portion 33 are preferably provided so as not to hide the right-eye image main portion 88 and the left-eye image main portion 89. The right-eye image main portion 88 and the left-eye image main portion 89 indicate a portion that is particularly desired to be stereoscopically viewed among the stereoscopically viewed images, and can be arbitrarily determined depending on the stereoscopically viewed image. In the present embodiment, the right-eye image main portion 88 and the left-eye image main portion 89 are set in the vicinity of the right-eye focus 86 and the left-eye focus 87. This is because the vicinity of the focal point 87 of the left eye is the range that can be stereoscopically viewed without any obstacles, and there are many cases in which objects to be stereoscopically viewed are often placed in this range, but it is necessary to limit to this. It can be arbitrarily determined depending on the stereoscopic image. In the present embodiment, the image 83 is displayed on the entire surface of the image posting unit 9 for easy understanding. However, the image displayed on the image posting unit 9 is for stereoscopic viewing, that is, the same subject. As long as it is at least two images represented from different angles, the images may not be displayed on the entire image posting unit 9.
