[0005] As a principle of a moving image, a moving image has been conventionally known in which a picture having a motion gradually changed in a notebook shape is flipped over.

[0006]

The above-mentioned method can be easily realized because the structure is extremely simple. On the other hand, there were the following problems. (A) Since the images are limited to two types, they are poorly developed, lack interest, and have a very narrow use range. (B) A continuous movement could not be expressed at all because of only two screen changes, so that it was difficult to use it as a moving image, and its use effect was also thin. (C) In addition, there was a point at which half the fun for that must move the shielding tool 2 _0. (D) In the note method, since the shape is not planar, the range of the person who can see the movement is limited to change the movement, so that only a small area can be applied. The present invention has been invented in order to maintain the simplicity of this method and to solve these problems, and can be widely used.

[0007]

[0014]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a plan view for explaining the basic principle of the image change display device of the present invention. At the top of a composite image sheet 10 on which a grid-like composite image E created based on four types of images is arranged,
A mask sheet 20 in which a transparent portion and a shielding portion for making only one kind of original image visible are regularly arranged.

By the operation of the mask sheet 20, only one kind of original image in the composite image can be made visible. Therefore, by changing the cross-shaped character as a unit image using the cross-shaped character as a unit image, the mask sheet 20 is moved in a circular or pseudo-circular shape as shown in FIG. Image change can be obtained.

At the top of FIG. 1A, arrows (a) for turning the mask sheet in a square shape along the cross-shaped unit image and arrows (b) for moving the mask sheet in a circular shape. )It is shown. A continuous image composed of four unit images is used, and a moving image of four frames is visually recognized as a display image.

The principle shown in FIG. 1 (2) will be described for the minimum unit. If "Technical nation" is written in the unit image 001 of the composite image, the unit mask sheet 0
02 corresponds to the unit image, and since only one-quarter cell is opened to make only one kind of original image visible, the unit mask sheet 20 is sequentially placed.
If it is moved as shown by the arrow (a) or (b) in (1) of FIG. 1, the character of the unit image 001 and the technical nation will appear sequentially. That is, as shown in FIG. 1 (2), if the pieces are overlapped and moved squarely for each square, a technical nation appears. In this example, the movement is a kanji character. However, when the image is gradually moving like a moving image, for example, when the fireworks are opened, the number of units may be increased as shown in FIG. In this case, even if the unit mask sheet 002 was not strictly moved for each square, even in a circular motion or a pseudo circular motion, it was confirmed that the characters appeared sequentially. Hereinafter, the principle will be described in detail. In the present invention, a unit image is set as the minimum one unit, and is performed over all the cells. A more detailed description is given below.

As a principle of the moving image, a moving image in which a picture having a movement gradually changed in a notebook shape is conventionally flipped is known, but the present invention expresses this in a planar manner. It can be said. In addition, illustrations, photographs, characters, figures, colors, and the like are used as specific images.

The process of creating a grid-like composite image E arranged on the composite image sheet 10 will be described in detail below with reference to the drawings. In this example, the fireworks are formed in the order of flowering.

It is understood that the smaller the size and the denser the grid used in the creation of the composite image, the more the image quality can be prevented from deteriorating by thinning out the image. Will.

FIG. 1 shows the basic principle of the mask sheet 20 in the display device 1 according to the present invention. A method for producing the mask sheet 20 will be described below.

The mask sheet 20 is a composite image sheet 10
In accordance with the cross-shaped square, which is the unit image used when creating the composite image, the unit image with any one of the squares in the transparent state and the remaining three squares in the shielded state is minimized. The required number of units are arranged vertically and horizontally and completed. As a concrete realizing method, a method of applying a shielding material to a transparent resin film or the like, or performing an impregnation process to obtain a shielding portion, or perforating an opaque material such as paper, wood, metal, or resin And the like to obtain a transmission part.

The mask sheet 20 is moved by a hand or the like in a circular motion or pseudo-circular shape on the square-shaped square on the composite image sheet 10 so that the mask sheet 2 is moved.
Since 0 is formed as a minimum unit in which one arbitrary cell is in the transmission state and the remaining three cells are in the shielding state, four types of images are sequentially shown. The motion can be a moving image using an afterimage, in addition to a case where four types of images are sequentially formed as words having a linguistic connection.

FIG. 18 shows the relationship between the mask sheet 20 and the composite image E. Here, the composite image mask sheet 20 overlaps E on the composite image sheet 10 having a through transmission portion, and shows a state where the display image A ₀₁ is a kind of four types appearing.

Next, in FIGS. 19, 20, and 21, the mask sheet 20 is moved, and the remaining three types of display images B ₀₁ and B ₀₁ are displayed.
The display image C ₀₁ and the display image D ₀₁ are shown.
Further, FIGS. 22 to 24 show display images at intermediate points when moving between the respective images.

FIG. 22 shows the _relationship between the display image A ₀₁ and the display image B ₀₁ .
23 shows the display image B ₀₁ and the display image C ₀₁ , FIG. 24 shows the display image C ₀₁ and the display image D ₀₁ , and FIG. 25 shows the display image D ₀₁ and the display image A ₀₁ at the respective movement intermediate points. 4 shows a display image. Further, FIG. 26 shows a display image of the display image A ₀₁ is an intermediate point of the display image C _01, Note and at a point which is also the intermediate value of the display image B ₀₁ and the display image D _01.

The display images A ₀₁ to D ₀₁ show the process of so-called fireworks blooming, and the state in which the fireworks bloom can be displayed.

According to the present invention, moving images or characters, and changes in patterns can be recognized by superimposing the mask sheet 20 on the composite image sheet 10 based on the above principle. By utilizing this principle, an attempt is made to obtain a change in an image or an effect of a moving image without moving the mask sheet 20 as shown in FIG.

That is, as a result of an experiment in which the synthetic image sheet 10 and the mask sheet 20 are arranged with a gap therebetween, as a result of movement of a person in a parallel movement and a vertical movement, the person moves to a circular motion or a pseudo circular motion. It becomes a close movement and can recognize the change, etc., and the person has a learning ability to perform while identifying the screen by interest and curiosity for the object, and has an adjustment ability, so that it responds to or reacts to the change, It turns out that the user adjusts the screen while performing a circular motion as needed to discover. It was also found that the discovery was more interesting. Therefore, in the present invention, it has been found that the user can recognize the mask sheet 20 without moving the mask sheet 20 with respect to the composite image sheet 10. This is because the user has understood that the adjustment is performed by himself until the displayed image is visually recognized.

Therefore, in the above embodiment, the situation in which the fireworks are blooming is depicted, so that the fireworks launched by the afterimage effect seem to open continuously.

FIG. 2 shows an embodiment of the combination of the composite image sheet 10 and the mask sheet 20. In this example,
Although the above-described fireworks may be used for moving images, the same principle can also be used to display, for example, a movement in which a boy throws onto a ball and moves like a beanbag, or a elephant moves his legs.

In FIG. 3, a synthetic image sheet 10 is stretched on the back surface of the rectangular body 3 made of transparent acrylic resin, and a mask sheet 20 is stuck on the front side with an appropriate adhesive or the like. In this configuration, it can be adopted for an appropriate display device 1, but when a person passes through the display device 1, a moving image phenomenon and a change in characters and patterns are recognized.
If it is placed on a desk or in a shop window, it can be a noticeable display device. Here, the rectangular body 3 has a role of providing a gap between the composite image sheet 10 and the mask sheet 20. On the other hand, a person who views the display device 1 can display moving images, characters, and the like in the transparent rectangular body 3. When asked for the mechanism of change in the pattern, they feel suspicious and conduct their own research, which has the effect of further raising interest.

One of the reasons is that the movement of a person is not merely a parallel movement but a vertical movement, resulting in a circular or pseudo circular movement. Can be recognized.

FIG. 4 shows an embodiment which can be assembled from a sheet. As shown in FIG. 4 (2), the folded portions 01, 01, 01, the composite image sheet portion 101, and the mask sheet are formed on the sheet. A unit 201 and stand units 03, 03 serving as stands are provided. Then, the mask sheet portion 201 and the folded image portions 01, 01 at both ends of the composite image sheet portion 101 are joined by an appropriate bonding means or the like, and the stand portions 03, 03 are raised to assemble.

FIG. 5 shows an embodiment in which the display device 1 is suspended from a ceiling or the like with a string member 5 instead of being placed on a desk or the like. In this case, it is possible to rotate the display device 1 by wind or the like and perform an interesting movement simply by suspending the display device. However, as shown in FIG. The bar 51 is further suspended from the both ends by the strings 52, 52, and the bar 51 is further suspended by the strings 50. Since the string 50 is provided with a spring 500 interposed therebetween, the display device 1 includes a horizontal rotation, a pendulum motion, and a vertical motion. Is advantageous in that it is easy to detect a motion or a character change in a moving image.

FIG. 5 (2) shows an arrangement in which the rotation in the horizontal direction is prevented, and only the movement in the horizontal pendulum and the movement in the vertical direction are performed. The string member 5 suspends the bar 51 with a string 50, and under the bar 51, springs 510, 51 are provided.
0 suspends the display device 1. There are springs 511 and 511 on the side of the display device 1 to maintain and adjust the pendulum motion. A guide member 520 is provided at a lower end of the display device 1. At the lower end of the display device 1, the display device 1 is provided with a pointing member 53 provided on an installation surface or the like with respect to the display device 1.
Since the guide member 520 moves in the inside, horizontal rotation is prevented. Thus, it is restricted to vertical and lateral movement. Therefore, it can be seen that the movement is approximated to a pseudo-circular movement. In addition, the display device 1 can be supported by various support methods. It is needless to say that various support methods are applied by those skilled in the art based on the technical idea of the present invention.

The embodiment shown in FIG.
This is another embodiment in which is supported by an elastic body. The support shown in FIG. 6 is a support of the leaf-spring-like support members 6 and 6 and is supported below, and is provided on the stand 06. What is shown in FIG.
The support bars 70, 70 are suspended by the support bars 70, 70, and the support bars 70, 70 are attached to the stand 07. In this case, due to vibrations caused by people or cars,
Since the display device 1 itself vibrates, it promotes moving images and changes in character patterns.

As shown in FIG. 8B, the sheet is provided with a folding section 800, a composite image sheet section 810, and a mask sheet section 820. Then, in the folding section 800,
The composite image sheet portion 810 is folded with a gap with respect to the mask sheet portion 820, sandwiched as shown in FIG. 8 (2), and assembled. Also in the present embodiment, since the person notices the movement of the display device and reacts, and learns to confirm the reaction by himself, the circular motion on the display device itself performs a pseudo circular motion, so・
Some ads are even more effective.

In this embodiment, although it can be easily manufactured, it is not only placed on a desk but also suspended from above as shown in FIGS. It is also possible for people to appreciate.

Another embodiment shown in FIG. 9 relates to a foldable display device 1 and is assembled and completed.

The other embodiment shown in FIG. 10 is the same as that of the embodiment shown in FIG. Equivalent to From the sheet shown in (2) of FIG. 10, the display device 1 is foldable and is assembled and completed. That is, as shown in FIG. 10B, the sheet is provided with folding portions 102 and 103 serving as the stand portion 100 at one end of the mask sheet portion 120. The folding part 102,
103, as shown in (1) of FIG. 10, is folded into a chevron to serve as a stand,
No. 2 is folded so that it can be inserted between the combined image sheet portion 110 and the mask sheet portion 120. Then, the composite image sheet section 110 is bent with respect to the stand section, and inserted between the stand section 100 and the mask sheet section 120. As shown in (1) of FIG. 10, it is sandwiched and assembled. The fixing may be performed by providing a suitable cut-and-raised portion, or by using a suitable adhesive or a cellophane tape. When assembly is complete,
It can be set up as a stand on a desk or the like.
Of course, since the length of the composite image sheet portion 110 is longer than that of the mask sheet portion 201, when the composite image sheet portion 110 is inserted, the composite image sheet portion 110 has an arc shape, and a necessary gap is provided between the two.

FIG. 11 shows an embodiment in which the display device 1 is provided in a show window of a department store or the like based on the same principle. In the figure, an elephant illustration is set and the legs are set to move. As many people pass, the effect is outstanding, as the passers-by notice the change in the show window. Further, in order to obtain a further effect, a hill-like body 11 that rises and falls is provided in advance on the road surface, and a circular motion phenomenon may be caused every time the hill-like body 11 passes, which is more interesting.

FIG. 12 shows an embodiment in which the vehicle is installed outdoors such as an automobile road. When a vehicle passes, the vehicle itself moves up and down. Video, text, and pattern changes occur. In particular, this phenomenon can often occur where there are irregularities on the road surface. There is a wavy portion 12 as a sleepy road portion at the end point of a highway or the like, but at such a point, vertical movement will occur and the power will be more exerted. In any case, in the vehicle,
Since the passenger and the vehicle themselves also move up and down lightly, the movements and changes themselves are discovered by themselves, and the display device of the present invention exerts further effects. Of course, it may be installed not only on cars but also on the tracks of trains and locomotives,
The effect is great along railway lines where commuter trains pass.

The embodiment shown in FIG. 13 uses the signboard-shaped embodiment shown in FIG. 12 to vibrate the display device 1 by using the wind or the vibration of a car to promote the animation or the change of the character pattern. The display device 1 includes support members 13, 13.
As shown in FIG. 13, it is suspended by ropes 130, 130, and the lower end is fixed via springs 131, 131. The upper part is suspended by a rope 130 so as to be easily moved in the horizontal direction, and the lower end is connected to a spring 131. In any case, it is understood that the robot is supported so as to be able to perform horizontal movement in addition to vertical movement. Of course, the lower end may be a rope instead of a spring. In the embodiment shown in FIG. 13 (2), there are spring springs 131 on the upper and lower sides to support the display device 1.

As described above, a display device in which the composite image sheet 10 and the mask sheet 20 are integrated can recognize a moving image phenomenon, a change in characters, patterns, and the like simply by installing the display device.

In each of the embodiments, the description has been made with a moving image.
Needless to say, a character array having a static meaning may be used. For example, if a character arrangement such as “Giant champion” is used, the character arrangement can be displayed even when performing a square or circular motion, so it will be more exciting, and various changes are made using four kinds of changes. Display becomes possible. Also, if you arrange various patterns,
You can also display gorgeous changes like a kaleidoscope,
Also, utilizing the above principles of the present invention, several types of display devices can be applied by those skilled in the art.
