Description

  The present invention introduces external light into a dark box provided with a peephole for peeping with both eyes, and represents a fictitious constellation or star cluster in a three-dimensional display of light spots in the space in front of the dark box. The present invention relates to a dark box light spot stereoscopic display toy having a function of moving a displayed light spot in a perspective direction.

  Conventionally, there have been toys that display a three-dimensional image using a mirror, prism, lens, etc., but as in the present invention, a light spot is displayed in a three-dimensional space without using an optical system such as a mirror, prism, lens or the like. In addition, there was no simple and inexpensive toy with the function of moving the light spot in the perspective direction.

  No conventional toy expresses a mysterious starry sky by displaying a light spot whose position is determined in a three-dimensional space, and there is nothing that can move the light spot in the perspective direction. By displaying a light spot with a fixed position in a three-dimensional space, it expresses a fictitious starry sky, gives it beauty and mystery that can be appreciated, and overuses it for work and study that often keeps looking at nearby places By displaying the light spots in the distance of the eyes, replacing them with the foreground and the distant view by them, working the focus adjustment function of the eyes by looking at them, and adding a mechanism to move the light spots in the perspective direction, The task was to work the focus adjustment function of the eyes just by looking at the light spot while improving mystery.

  As shown in FIG. 1, the invention of claim 1 for solving this problem includes a thin film 2 on the front surface of the dark box 1, a right peeping hole 3 peeking with a right eye on a rear surface, a left peeping hole 4 peeking with a left eye, a thin film 2 and a rear surface. A light selective separation film 5 is provided in parallel with the thin film 2, a fixed star 6 is set in front of the dark box 1 and a position to be an imaginary light spot is fixed, and a straight line connecting the fixed star 6 and the right peeping hole 3 The light selective separating film 5 is provided with a right-eye light introducing small hole 7 at the point where the thin film 2 intersects, and a right-light selecting middle hole 8 that is necessary and sufficient for the right-eye light introducing small hole 7 to be seen from the right peeping hole 3. Similarly, the left eye light introduction small hole 9 is formed at the point where the straight line connecting the fixed star 6 and the left peep hole 4 and the thin film 2 intersect, and the left eye light introduction small hole 9 is necessary and sufficient to be seen from the left peep hole 4. Are provided in the light selective separation membrane 5.

  Next, in order to solve the problem of moving the imaginary light spot in the perspective direction, a moving star 11 that is an imaginary light spot whose position moves in front of the dark box 1 is set, and the moving star 11 and the right peephole 3 are set. The right moving thin film piece 12 is provided so as to cross the connecting straight line. One end of the right moving thin film piece 12 is joined to the thin film 2 at the joining portion 14 via the stretchable portion 13 which can be stretched by bending. An operating handle 16 extending outside the dark box 1 through the through frame 15 is provided, and a right moving light introducing small hole 17 is formed at a point where the straight line connecting the moving star 11 and the right peeping hole 3 and the right moving thin film piece 12 intersect. The thin film 2 is formed as a hole having a size and shape that does not obstruct light at each position of the thin film 2 on the path for introducing light from the moving star 11 to the right peephole 3 through the right moving light introducing small hole 17 and the light selective separation film 5. The right thin film middle hole 18 and the light selective separation film 5 have the right light selective elongated hole 19. Similarly, the left moving thin film piece 20 is provided so as to cross the straight line connecting the moving star 11 and the left peeping hole 4, but one end of the left moving thin film piece 20 is bent through the expansion / contraction part 13 which can be expanded and contracted. The operation handle 16 extended to the outside of the dark box 1 through the through frame 15 is provided at the other end of the thin film 2 at the joint 14, and a straight line connecting the moving star 11 and the left peeping hole 4 and the left moving thin film piece 20 are provided. A left moving light introduction small hole 21 is opened at the intersection, and the thin film 2 and the light selective separation film 5 on the path for introducing light from the moving star 11 to the left peeping hole 4 through the left moving light introduction small hole 21 are respectively positioned. A left thin film middle hole 22 is provided in the thin film 2 and a left light selective horizontally elongated hole 23 is provided in the light selective separation film 5 as holes having a size and shape that do not obstruct light.

  In order to display the moving star 11, the purpose of the moving star 11 can be achieved even if only one of the angles of light incident on the left and right eyes is changed. Therefore, the other one is regarded as the fixed star 6. You may provide each opening part for ensuring the path | route which introduces light.

  When setting a plurality of close fixed stars 6, they are treated as one fixed star 6, and the light from these passes through one right light selection hole 8 and left light selection hole 10 in a similar manner. When setting a plurality of close moving stars 11, they are also treated as one moving star 11, and the light from these is also passed together through one right light selection horizontal hole 19 and left light selection horizontal hole 23. Even if only one of the angles of light incident on the eye is changed, the purpose as the moving star 11 can be achieved. Therefore, either one is treated as a fixed star, and the right light selection hole 8 and the left light selection hole 10 are used. You can pass either one.

  As shown in FIG. 2, the invention of claim 2 is colored transparent at any position of the thin film 2 on the straight line for introducing light from the fixed star 6 to the right peephole 3 and the left peephole 4 and the light selective separation film 5. The body 24 is attached so that a colored light spot can be expressed, and can be used for the moving star 11.

  The invention of claim 3 has a portion that uses the light of the artificial light emitter 25 such as a light emitting diode instead of external light as shown in FIG. 3, and supplies electricity to the artificial light emitter 25 through a control circuit. By doing so, it becomes possible to control the brightness of the light spot, and it is possible to display light spots of different colors by using the artificial light emitters 25 having different emission colors.

  As described above, in each figure, a path for introducing light from an imaginary light spot to the vicinity of the center of the right peeping hole 3 is a right light introduction path line display line 26, and light from an imaginary light spot is lighted to the left peephole 4. The path to be introduced to the vicinity of the center is represented as a left light introduction path streak display line 27.

  The present invention is configured as described above, and sets the imaginary light spot at the same position as the direction of light incident on the left and right eyes when the light spot is actually in front of the dark box 1, and is used for the right eye. There is no distinction in the direction of light entering the left and right eyes from the light introduction hole 7 and the light introduction hole 9 for the left eye through the opening provided in the light selective separation film 5, and the actual light at the position of the imaginary light spot. It can be recognized that a point exists.

  Also, whether the light spot is far or near is due to the difference in the direction of the light incident on the left and right eyes, and if the direction of the light incident on the left and right eyes is parallel, the distance is infinite. The light spot is recognized as being closer to the light beam so that the left and right eyes face inward. In the present invention, the right movement light introduction small hole 17 and the left movement light introduction small hole 21 are moved by moving the operation handle 16. Since the direction of light introduced into the left and right eyes from these holes changes, the display position of the imaginary light spot can be changed in the left and right and perspective directions accordingly.

  As described above, the present invention can display an imaginary light spot at a position at infinity from immediately before the eye, and can display an imaginary constellation or a plurality of light spots that are close to each other to express an imaginary star cluster. Can move, color, and blink the light spots.

  From the above, in addition to being effective as an ornamental toy, the present invention appears that each star constituting a real constellation is equidistant from the earth. The distance is different, and it can be used as a science teaching material because it can embody the difference in distance, and it is better to look at distant scenery to relieve eye tension, but it was set at a far distance It can be used as a substitute for a distant landscape with a light spot, and in addition, the present invention has an advantage that it is easy to stare because it looks at a point unlike a landscape of a surface.

  In addition, since the light spot can be moved in the perspective direction, the eye focus adjustment function can be activated by moving the light spot in the perspective direction while staring at the light spot, and further, by coloring and blinking the light spot Advantages such as making it easier to point out a light spot that suits the purpose, making it easier to point to a specific light spot when using it as a learning material for learning constellations, or when giving an appropriate stimulus to the focus adjustment function of the eye There is.

  As shown in FIG. 1, a thin film 2 is provided on the front side of the dark box 1, a right peeping hole 3 for peeping with the right eye on the rear surface, a left peeping hole 4 for peeping with the left eye, and a light selective separation film 5 provided between the thin film 2 and the rear surface. An imaginary fixed star 6 whose position is fixed in front of the dark box 1 is set, and a right-eye light introduction small hole 7 is provided at a point where the straight line connecting the fixed star 6 and the right peephole 3 and the thin film 2 intersect. External light is introduced from the light introduction small hole 7 to the right peeping hole 3, and in order to introduce the light only to the right eye, the right light selection inner hole 8 is located at a position where the light path and the light selective separation film 5 intersect. Similarly, in order to introduce light into the left eye, a left-eye light introducing small hole 9 is provided at a point where the straight line connecting the fixed star 6 and the left peeping hole 4 and the thin film 2 intersect with each other, and from the left-eye light introducing small hole 9 External light is introduced into the left viewing hole 4, but the light path and the light selective separation film 5 cross each other in order to introduce the light only to the left eye. By providing the left light-selected hole 10, and displays the fixed stars 6.

  Next, in order to move the imaginary light spot in the perspective direction, a moving star 11 that is an imaginary light spot whose position moves in front of the dark box 1 is set, and a straight line connecting the moving star 11 and the right peephole 3 is set. A right moving thin film piece 12 is provided so as to cross, but one end of the right moving thin film piece 12 is joined to the thin film 2 at the joining portion 14 via an expansion / contraction portion 13 that can be expanded and contracted, and the dark box 1 is connected to the other end. An operating handle 16 extended outside the dark box 1 through the penetrating frame 15 is provided, and the right moving light introducing small hole 17 is formed at the point where the straight line connecting the moving star 11 and the right peeping hole 3 and the right moving thin film piece 12 intersect. A hole having a size and a shape that does not obstruct light at each position of the thin film 2 and the light selective separation film 5 on the path for introducing light from the moving star 11 to the right peeping hole 3 through the right moving light introducing small hole 17. The right thin film inner hole 18 in the thin film 2 and the right light selective horizontal length in the light selective separation film 5 19 is provided, and the left moving thin film piece 20 is provided so as to cross the straight line connecting the moving star 11 and the left viewing hole 4. The operating handle 16 extended to the outside of the dark box 1 is provided through the through frame 15 that is passed through the dark box 1 at the other end, and the moving star 11 is connected to the left peeping hole 4. A thin film 2 on the path that opens the left moving light introducing small hole 21 at the point where the straight line and the left moving thin film piece 20 intersect, and introduces light from the moving star 11 to the left peeping hole 4 through the left moving light introducing small hole 21, light selection A left thin film middle hole 22 is provided in the thin film 2 and a left light selective horizontal long hole 23 is provided in the thin film 2 as a hole having a size and shape that does not block light at each position of the separation film 5.

  It should be noted that the right thin film middle hole 18, the left thin film middle hole 22, the right light selection laterally long hole 19, and the left light selective laterally long hole 23 each have a path of light passing through each opening, the right moving thin film piece 12, Since the moving thin film piece 20 moves to the left and right by the movement of the moving thin film piece 20, it is set to be long in the horizontal direction so as to correspond to the movement, but these parts have the same moving mechanism as the right moving thin film piece 12 and the left moving thin film piece 20. So that each opening can be built small.

  A plurality of right moving thin film pieces 12 and left moving thin film pieces 20 may be provided. Each of the right moving thin film pieces 12 may have a plurality of right moving light introducing small holes 17 and each of the left moving thin film pieces 20 may have a plurality of left moving thin film pieces 20. The moving light introducing small holes 21 may be provided, which makes it easy to increase the number of moving stars 11 to be displayed.

  Light from a plurality of approaching fixed stars 6 passes through one right light selection hole 8 and left light selection hole 10 together, thereby making it possible to easily display a fictitious star cluster in which the stars are dense. In the same way, the light from a plurality of close moving stars 11 has a portion through which one right thin film middle hole 18, left thin film middle hole 22, right light selective horizontal hole 19, and left selective horizontal hole 23 pass. Thus, there is a form that makes it easy to move an imaginary star cluster with dense stars. (Partly shown in FIGS. 1 and 5)

  In the present invention, the moving star 11 is displayed by changing the incident angle of the light from the light spot incident on the left and right eyes, but either one of the incident angles of the light incident on the left and right eyes is realized. Since the position of the light spot is changed and recognized only by changing the angle of, and the purpose as the moving star 11 can be achieved, one of the light from the moving star 11 incident on the left and right eyes is the same as the fixed star 6. There is a form in which the opening is not changed. (Partially shown in FIGS. 1 and 6)

  FIG. 2 shows a colored transparent material such as a cellophane which is transparent and has a color at any position of the thin film 2 on the path for introducing light into the right peeping hole 3 and the left peeping hole 4 from an imaginary light spot. In this configuration, the body 24 is provided to enable display of colored light spots.

  FIG. 3 shows a mode in which the light from the artificial light emitter 25 is introduced into the dark box 1 instead of introducing external light. A light emitting diode is used as the artificial light emitter 25 and a shielding cylinder 30 that blocks unnecessary light is put on the dark box 1. Attached to the thin film 2, the light spot is color-coded by using different light-emitting diodes, and the brightness of the light spot is changed by supplying electricity through a general control circuit. It is a form that makes it possible.

  Since the stretchable portion 13 of the present invention is bent, it can be easily deformed to allow left and right movement while suppressing unnecessary vertical movement of the right moving thin film piece 12 and the left moving thin film piece 20, and to be in close contact with the thin film 2. Thus, although unnecessary light from the outside is prevented from entering the inside, the stretchable portion 13 may be formed of an elastic body such as a thin plate-like rubber.

  Further, in FIG. 4, a plate-like sliding frame 28 having one end joined to the thin film 2 and the other end on the opposite side floating from the thin film 2 to provide a gap is provided so that the gap portions face each other, and rightward movement is performed in the gap. The thin film piece 12 is constructed so as to slide, and the right moving thin film piece 12 can be brought into close contact with the thin film 2, and the right moving thin film piece 12 is suppressed while preventing unnecessary light from entering from outside and unnecessary vertical movement. It is possible to make use of the left moving thin film piece 20 as well.

  FIG. 5 shows a structure in which a plurality of small moving thin film pieces 29 are connected via the expansion / contraction part 13 to have a function as one right moving thin film piece 12. Since the pieces 29 move by different amounts, and each moving star 11 represented by the right moving light introducing small hole 17 on each small moving thin film piece 29 shows different amounts of movement, the expression of the present invention is broadened. This is a form that is provided, and can also be used for the left moving thin film piece 20.

  In the present invention, the darker the dark box 1 is, the more the light spot is emphasized. Therefore, it is better to reduce the intrusion of unnecessary light from the portion where the operation handle 16 penetrates the dark box, but this is a common sense technique. In the related drawings, a configuration in which unnecessary light does not enter the eye directly from the outside by passing the operation handle 16 through the through frame 15 is shown.

  Furthermore, by providing a sponge-like elastic body or the like between the penetrating frame 15 and the operation handle 16, there is a form in which the entry of light from the outside can be further reduced. (Not shown)

  Also, the right moving thin film piece 12, the left moving thin film piece 20, and the parts related to them are placed outside the thin film 2 so that the light does not enter from the vicinity of the operation handle 16 and is placed in the dark box 1. There is a form in which the penetrating light is eliminated by moving the operation handle 16 using electrical means such as an electromagnet or a motor, or mechanical means such as a mainspring, thereby eliminating the portion penetrating the dark box 1. (Not shown)

  If a plurality of fixed stars 6 are dispersed and displayed on an average from a short distance to a far distance, the fictitious near and far points can be viewed according to the purpose, and the focus adjustment of the eye, which is the subject of the present invention Since the purpose of functioning can also be achieved, there is a form that can satisfy most of the problems of the present invention even if only the fixed star 6 is displayed, and can be manufactured more easily and inexpensively. (Not shown)

  A plurality of light selective separation films 5 may be provided at intervals. In a single light selective separation film 5, when the number of light spots to be displayed is increased, the number of openings in the light selective separation film 5 increases, and through the openings. The light that is to be incident on the right eye is likely to cause unnecessary light lines that are incident on the left eye and the light that is to be incident on the left eye is incident on the right eye. However, the provision of a plurality of light selective separation films 5 can reduce this problem. There is a form that can. (Not shown)

  Further, FIG. 6 shows a mode in which the light selective separation membrane 5 is installed in the direction perpendicular to the thin film 2 between the middle part of the right peeping hole 3 and the left peeping hole 4 and the middle part of the thin film 2. When an imaginary light spot is set at a position where incident light has a streak intersecting with the light selective separation film 5, the opening in the thin film 2 for introducing light at the light spot is the light selective separation film 5. However, there is a problem that unnecessary light is incident on the left eye from the opening, and the setting position of an imaginary light spot where such a problem occurs is an outside region away from the front center part of the dark box 1. Therefore, by removing these areas and setting an imaginary light spot only in the front center part of the dark box 1, there is a form that does not require an opening in the light selective separation film 5 and is easy to manufacture with a simpler structure.

  In the present invention, a star is expressed by a light spot, and it is preferable that a hole for introducing light serving as a light spot is small. However, since the hole is small, the inside of the hole for introducing light to the left and right eyes for some reason. , There is a high possibility that one of the light spots will be blocked, but when there are very few light spots compared to the number of normal light spots, light is incident only on the right or left eye and displayed. When the light spot is mixed with many normal light spots scattered in the three-dimensional space, the position is not fixed, and it seems that the thread is pulled infinitely far from immediately before the eyes, at least in either planar or three-dimensional space There is a form in which a light spot that is displayed by introducing light into only the right or left eye is positively incorporated in advance. (Not shown)

  In the present invention, when external light is introduced into the dark box 1 to display a light spot, a difference occurs in the intensity and color of light introduced into the right peeping hole 3 and the left peeping hole 4 depending on the external light condition. However, by installing a ground glass-like film that transmits and scatters light in the front part of the dark box 1, the intensity and color of the light to be introduced can be made uniform and the problem can be solved. Even when external light and artificial illuminant 25 are used in combination, they can be installed on the outside, the ground glass-like film forms the appearance of the main body, and the openings of the thin film 2 are not visible, making it difficult to guess the structure. There is a form that can give a mysterious feeling. (Not shown)

  In the present invention, the positions of the left and right eyes are determined and used. This is achieved by looking through the right peeping hole 3 and the left peeping hole 4, but the head is fixed by a common sense method. Thus, there is a form in which the positions of the left and right eyes are determined, and the right peeping hole 3 and the left peeping hole 4 are not independent openings. (Not shown)

  An apparatus for stereoscopically displaying the light spot according to the invention is useful for relieving eye tension, for ornamental purposes, for teaching materials, and can be easily industrially mass-produced by conventional techniques. With the availability of
