Description

  The present invention relates to a method of displaying a plurality of related images by lighting / extinguishing a light source, shielding / releasing, and dimming.

  An electric signboard that displays a single image drawn on a translucent material by irradiating light from the back to a passage of a station or a shopping center is widely used. As the light source, fluorescent lamps, LED lamps, EL sheets and the like are common.

  Also, Patent Document 1 proposes an image scroll unit that can easily change a display image. As described above, an apparatus having a light source on the back side is also known in which a translucent material in which a plurality of images are arranged or a translucent material on which an endless pattern is formed is scrolled.

  A sheet having a lenticular lens in which a different image can be seen depending on the viewing angle is also known. A lenticular lens is lined with lenticular lenses, and the left and right eyes see the same image at the same time, and the effect of switching images and animation can be obtained. 3D images can be viewed using the sheet placed in Furthermore, if image data of a frame is created by using software for morphing composition, morphing expression in which one image changes to a different one can be performed.

  On the other hand, the inventor applied for a patent (Patent Document 2) for a multiple image display method and apparatus for displaying two or more types of images on one surface by turning on and off the light source or by shielding and releasing light. Yes. Depending on the presence or absence of light from the light source, the back image formed on the translucent material and the front image formed on the light-blocking multiple holes or slit material can be switched to express movement, surprise, fun, etc. Is the method. When a light-blocking porous substrate such as a one-way vision material with a front image is installed on the light source, the front image can be seen when the light from the light source does not hit, and when the light hits, many holes or transparent from the rear side Since light comes out through the stripes, the front side becomes a shadow, and only a dark color is perceived visually. When an image formed on a translucent substrate that can transmit light sufficiently is sandwiched between a light source and a light-shielding porous substrate, this illumination image can be seen through a hole in the light-shielding porous substrate when exposed to light. . This is the principle of giving a motion by continuously projecting different images visually by waiting for the relevance of the image and repeatedly shielding and releasing the light.

In addition, the inventor has applied for a patent for an image sheet used in the multi-image display method and apparatus for displaying two types of images on one surface by turning on / off the light source or shielding / releasing light (patent) Reference 3). A surface image consisting of three layers of a light-shielding dark color layer, a white color layer, and an image layer is formed on the surface of a translucent or transparent substrate with an aperture ratio of 25% to 70%. This is an image sheet that is formed. Instead of preparing two images by forming an image on a light-shielding porous substrate and a light-transmitting material, the effect of switching two images on one side depending on the presence or absence of light from a light source Is made possible by forming two images on one material.
Patent Publication 2003-114628 Patent application 2007-94402, 341651 International application PCT / JP2008 / 053610 Patent application 2008-106204

However, the various conventional techniques described above have the following drawbacks. Although the conventional electric signboard can display an image beautifully, it displays a single still image and cannot exhibit an effect that attracts attention by switching the image.
A display device having an image scroll unit can move an image on a translucent material and has a relatively high degree of attention, but cannot express more than the sequential display of images.
In addition, the lenticular lens method can display images by switching them, but a lenticular lens sheet is required for each display unit, which requires a complicated operation of cutting out and synthesizing a plurality of images. In order to view these images, there are restrictions such as moving the lenticular lens sheet or moving the viewer.
The multi-image display method and apparatus for which the present inventor has applied for a patent (Patent Documents 2 and 3) is surprised because the rear image can be displayed or hidden by changing the front image depending on the presence or absence of light from the light source. Although it can produce enjoyment, the content and types that can be changed are limited. The motion that can be obtained visually by the afterimage was not smooth, and it was possible to move only like a frame drop.

  Therefore, an object of the present invention is to produce surprise and fun by switching images on two different materials on one side, and at the same time, images on different materials appear to interfere with each other instead of switching completely. Expression, morphing-like expression that changes the degree of interference steplessly or stepwise to change the image smoothly to another image, increase the number of images that can be switched by scrolling, smooth change of the background, etc. It is to provide a way to make it.

In order to achieve the above object, the present invention according to claim 1 arranges the second image (back image) formed on the translucent material on the rear side of the first image (front image) formed on the fluoroscopic substrate. A first porous image (front image) waiting for light-shielding properties is formed behind the two image sheet sets or on one side of the translucent material, and a second image (back image) is formed on the back side. A flashable light source or a light source capable of controlling the amount of light passing is arranged behind the formed image sheet, and the front image is displayed when the light does not hit the light transmissive material. The back image is displayed when the maximum amount of light hits the screen, and when the intermediate amount of light hits the translucent material, the interference image between the front image and the back image is displayed. This is a multi-image display method for displaying a moving image.

The operation of the present invention according to claim 1 is as follows. That is, the second light source formed on the translucent material on the rear side of the first image (front image) formed on the fluoroscopic base material, above or in front of the blinking light source or the light source capable of controlling the light passage amount. When two image sheet sets on which images (back images) are arranged are installed, or a first porous image (front image) waiting for light-shielding properties is formed on one side of a translucent material, and a second image is formed on the back side. When one image sheet on which an image (back image) is formed is installed, the light on the translucent material or the image on the front side can be seen.
When the maximum amount of light hits the translucent material, light comes out from the rear side through many holes or transparent stripes, so that the front side becomes a shadow, and only a dark color is visually recognized. The situation is exactly the same as when a bright room is seen through from a dark room. When an image formed on a light-transmitting material capable of sufficiently transmitting light is sandwiched between the light source and the fluoroscopic base material, the image can be seen through a large number of holes or transparent stripes on the fluoroscopic base material when the light source is turned on.
Each time the light source is blinked, or the light is blocked / opened, a different image can be instantaneously projected.
If the amount of light hitting the translucent material is reduced, the light coming out from the rear side through many holes or transparent stripes becomes weak, so switching is incomplete. Instead of completely erasing the front image, it can be shown to interfere with the back image. In the case of color, if the front image is yellow and the back image is blue, green can be expressed.

The fluoroscopic base material includes not only those having a large number of holes such as round holes but also those having a large number of slits (stripes) formed therein. The holes and slits in the base material include those printed on a transparent base material so that a large number of circular portions and slit portions remain as transparent portions in addition to the through holes. The translucent material is a transparent or translucent substrate. Examples of the translucent substrate include a milky white translucent substrate and a white coat transparent substrate. The perforated base material, the translucent material, and the light source that can be seen through may be disposed in contact (overlapping) or may be disposed with a gap therebetween.
Further, the see-through base material and the translucent material are not limited to a planar shape, and may be installed in a circumferential surface shape, a conical surface shape, or the like.
The light source may be a point light source, a line light source, or a surface light source. The blinking interval of the light source is selected in such a range that the front image and the back image are continuously viewed as moving images. Generally, about 0.25 seconds to 10 seconds is preferable. However, the lighting time and non-lighting time of the light source need not be the same, and the blinking interval may be irregular. The brightness of the dimmed light source is set according to the desired degree of interference. To reduce the degree of interference, the brightness is increased extremely, but conversely, it should be decreased extremely. The light source can be dimmed by adjusting the voltage for an incandescent bulb, using an inverter transformer for a fluorescent lamp, and using a general method such as software PWM for an EL sheet or LED lamp. If the passage amount is controlled (dimming) with the luminance of the light source as it is, the opening amount of the passage amount control device may be adjusted.

  The present invention according to claim 2 is the multi-image display method according to claim 1, wherein the second image (back image) formed on the translucent material on the back side of the first image (front image) formed on the fluoroscopic substrate. ) Is used, a second image (back image) is formed on the back surface of the translucent substrate using a translucent substrate as the translucent material. This is a multiple image display method.

  The operation of the present invention according to claim 2 is as follows. In the case of using two image sheet sets, the second image (back image) may be formed on either the front or back side of the translucent material, but a translucent base material is adopted as the translucent material, If an image (back image) is formed on the back surface of the translucent substrate, it is difficult to see the image from the viewer side, and the first image (front image) can be more clearly viewed when not exposed to light. Note that the second image (back image) formed on the back surface of the translucent material is not a normal image but is always an inverted mirror image so as to be viewed as a normal image from the viewer side.

According to a third aspect of the present invention, in the multiple image display method according to the first or second aspect, in the light source dimming step or the light passing amount control step, the luminance or the passing light amount is continuously or stepwise. This is a multi-image display method characterized in that the degree of interference between the front image and the back image is changed continuously or stepwise by changing them continuously.

  The operation of the present invention according to claim 3 is as follows. If the light is turned on after setting the intermediate brightness of the light source, the displayed table image instantly changes to the set interference image, but if the brightness is changed continuously or stepwise when the light is turned on, the degree of interference of the image gradually increases. Can be made smaller or smaller.

  According to a fourth aspect of the present invention, in the multiple image display method according to any one of the first to third aspects, instead of blinking the light source, the passage amount of the light emitted from the continuously lit light source is controlled. As a means for changing the display image by the above, a multi-image display method characterized by adopting a shutter device made of an openable / closable shielding material divided into a plurality of small pieces installed between the translucent material and the light source.

  The operation of the present invention according to claim 4 is as follows. By adopting a shutter device consisting of multiple small pieces as a device for repeatedly shielding and releasing light emitted from a light source that continuously lights up, it is possible to switch images faster than devices that move a large shutter that covers the entire image. To do. In addition, the selection range of the light source can be expanded to a light source such as a phosphorescent material that cannot blink, or a fluorescent lamp that is slow in blinking or has a remarkable shortening of life due to blinking. Furthermore, if the opening of the shutter is adjusted, the amount of light hitting the translucent material can be increased or decreased without changing the brightness of the light source. If this is used as the light control means, the electrical light control device can be omitted. Note that the shutter device is installed between the translucent material and the light source at a position sufficiently away from the image to the extent that the shadows of the opened small pieces do not hit the image.

  The plurality of small pieces of openable / closable shielding materials may be a material in which a plurality of porous materials with light-shielding multi-row slits are stacked in front of the light source. If the slit overlap is adjusted by sliding, the amount of light hitting the translucent material can be increased or decreased. In the example in which the shutter is composed of two porous materials, the width of the slit (light passage opening) of the porous material is 50% or less. When the slit width is 4 mm and the light shielding part width is 6 mm, if the two slit parts are completely overlapped, light will pass through the slit of 4 mm width, and if the slit part center is aligned with the light shielding part center, the light shielding part width will be However, the light is completely shielded. If it is between these two positions, an intermediate amount of light is transmitted. If the number of porous materials to be stacked is increased to reduce the necessary light shielding width per sheet, the amount of light transmitted from the slit can be increased. For example, with three sheets, the slit width of the porous material can be 60%. When the slit width is 6 mm and the light shielding part width is 4 mm, if the three slit parts are completely overlapped, light passes through the 6 mm wide slit, and when the light shielding part 4 mm is joined, the light shielding part width becomes 12 mm. Since is wider than the slit pitch of 10 mm, light can be completely blocked.

According to a fifth aspect of the present invention, in the multi-image display method according to any one of the first to fourth aspects, a portion in the front image that is desired to be continuously displayed even when light from a light source hits the back image When there is an image, in the method using two image sheet sets, the same image as the partial image is formed on a light-shielding base material without a hole, and is pasted on the front or back surface of the front image or the back image Or a dark material having a light-shielding property having no holes of the same shape as that of the partial image is pasted on the front or back surface of the front image or the back image, and in the method using one image sheet, The same image as the image is formed on a light-shielding base material without a hole and pasted on the upper side of the front image (front side of the light-transmitting material), or the light-shielding material without a hole having the same shape as the partial image On the upper side of the back image (the back side of the translucent material) Or only the partial image of the front image is formed into a complete image without an opening, or the opening of the partial image of the front image is filled with a shading dark color layer, or the back image In the multi-image display method, only the partial image is formed into a dark solid image.

According to the fifth aspect of the present invention, even when the light source is turned on or when light from the light source is released, the partial image is viewed as an image on an opaque material, not as a semi-transparent illumination image. That is. That is, in the method using two image sheet sets, the same image as the partial image on the fluoroscopic base material is printed on a light-shielding material without a fluoroscopic part, cut out, and attached to the front surface or the back surface thereof to shield the light. When pasted on the front surface, the back side of the partial image becomes the adhesive surface, and when pasted on the back surface, the partial image front side becomes the adhesive surface. Thereby, even when the light source is turned on or the light from the light source is released, the partial image on the fluoroscopic substrate can be continuously displayed. The same effect can be obtained even if a dark cut-off light-shielding material of the same shape and size, not an image, is attached to the rear surface of the transparent base material, or the front or back surface of the light-transmitting material. Further, the partial image on the translucent substrate may be solidly painted.
In the method using one image sheet, a complete image without a hole of the partial image is printed on a light-shielding material without a fluoroscopic part and cut out and pasted on the front image, or only the partial image is completely printed. A partial image is formed and shielded from light. Thereby, the partial image can be continuously displayed even when the light source is turned on or when the light from the light source is released. The same effect can be obtained by pasting a cut-out light shielding material of the same shape and size instead of an image on the back image, or by filling the front image opening with a light-shielding dark color layer only in the area of the partial image.
When the interference image is displayed with reduced light brightness, only the partial image can be shown as a complete image.

  According to a sixth aspect of the present invention, in the multi-image display method according to any one of the first to fifth aspects, the translucent material is provided behind the first image (front image) formed on the fluoroscopic substrate. In the case of using two image sheet sets in which the formed second image (back image) is used, the translucent material can be scrolled.

The operation of the present invention according to claim 6 is as follows. That is, by scrolling the light-transmitting material on which the back image is formed while the light source is on or light is released, the images formed on the light-transmitting material can be sequentially shown. Examples of the scroll device include a motor control of two sets of rollers arranged at both ends of the translucent film. As the scroll method, in addition to step feed such as frame advance, continuous feed may be performed so as to flow. The speed may be changed in the middle, or the scroll direction may be changed in the reverse direction. For these movements, if a partial image that can be viewed even when the light as described in claim 5 hits from behind is prepared, the stationary front partial image seems to move relative to the back background image. It is also possible to show to. If the light source is turned off or the light is shielded before or after scrolling, the back image disappears and the front image appears, or if the light intensity is changed, the degree of image interference changes. The width expands.
When the image is not flat, but formed in a cylindrical shape, for example, the image may be connected to the cylindrical shape and rotated instead of being taken up by rollers disposed at both ends of the light-transmitting material film.

  The present invention according to claim 7 is the multiple image display method according to any one of claims 1 to 6, wherein the partial light of the light source that hits the light-transmitting material is scrollable. Is the method.

The operation of the present invention according to claim 7 is as follows.
That is, when the light source is turned on or light is released, light is not applied to the entire surface of the translucent material, but a partial image on the translucent material that appears in the front image flows by scrolling the light. Change. Furthermore, if a partial image that can be visually recognized even from the back as described in claim 5 is prepared, the stationary front partial image moves in the opposite direction to the background image that changes so as to flow. It will be possible to look like As the scroll method, in addition to step feed such as frame advance, continuous feed may be performed so as to flow. The speed may be changed in the middle, or the scroll direction may be changed in the reverse direction. The intensity of the light applied partially may not be uniform throughout the entire part but may be distributed differently depending on the location. If the light source is turned off or the light is shielded before the start of scrolling, after stopping, or in the middle of scrolling, the back part image disappears and the front image appears.

  According to an eighth aspect of the present invention, in the multiple image display method according to the seventh aspect of the present invention, the partial light scroll of the light source that hits the light transmissive material may be the light transmissive material and the light source, or the light transmissive base material and the light transmissive material. This is a multi-image display method that is performed by scrolling a partially light-shielding material having an opening placed between the two.

The operation of the present invention according to claim 8 is as follows. That is,
The method of partial light scrolling by partially applying light to the translucent material is also a method of arranging LED lamps directly under the translucent material as light sources and sequentially selecting the lamps by program control to turn on / off / dim the light. good. This method has a high degree of freedom, but the cost is high. Instead of this, if a light-shielding material and a light source, or a partial light-shielding material having an opening between the transparent base material and the translucent material is placed and scrolled, the light-transmitted light can be transmitted without program control. It is moved so as to flow through the visible portion of the light material image. That is, the same effect can be obtained at low cost. Further, if the light shielding degree of the partial light shielding material is changed not depending on the entire surface but depending on the location, not only the image on the translucent material but also the flow of the image including the interference image with the surface image can be created. As the scroll method, in addition to step feed such as frame advance, continuous feed may be performed so as to flow. The speed may be changed in the middle, or the scroll direction may be changed in the reverse direction. If a part of the arranged partial light blocking material is provided with a completely open surface of light that can irradiate the entire surface of the image portion, the back image on the translucent material can be completely shown by stopping at that location. In an apparatus capable of scrolling a plurality of substrates, this place is selected and placed when scrolling the translucent material to show the entire image sequentially.

  The present invention according to claim 9 is the multiple image display method according to any one of claims 1 to 8, wherein the fluoroscopic substrate on which the first image (front image) is formed, and the second image (back side). This is a multi-image display method characterized in that, in the case of using two image sheet sets in which a translucent material on which an image is formed is arranged on the rear side, the fluoroscopic substrate can be scrolled.

  The operation of the present invention according to claim 9 is as follows. That is, by scrolling the fluoroscopic substrate on which the front image is formed while the light source is turned off or while the light is shielded, the images formed on the fluoroscopic substrate can be sequentially shown. Furthermore, by scrolling while the light source is turned on or when the light is released, the partial image that can be seen even when the light hits from behind is moved with the back image formed on the translucent material as the background. be able to. Examples of the scroll device include a motor control of two sets of rollers arranged at both ends of the fluoroscopic base film using a controller. As the scroll method, in addition to step feed such as frame advance, continuous feed may be performed so as to flow. The speed may be changed in the middle, or the scroll direction may be changed in the reverse direction. If the light source is turned off or the light is shielded before or after scrolling, the back image disappears and the front image appears, or if the light intensity is changed, the degree of image interference changes. The width expands. The range of expression can be further expanded by scrolling not only the see-through substrate but also the light-transmitting material or partial light.

  The present invention according to claim 10 is the multi-image display method according to any one of claims 1 to 9, wherein a translucent filter (mesh having no image) is provided between the fluoroscopic substrate and the translucent material. A material or a translucent material).

  According to the tenth aspect of the present invention, when the light source is not turned on or when the light is shielded, the image on the translucent material can be seen from the multiple holes or the striped fluoroscopic part and interfere with the image on the fluoroscopic substrate. May be unsightly. In such a case, it is difficult to see the image on the translucent material by inserting a mesh base material without an image or a translucent base material without an image between the translucent material on which the image is formed and the fluoroscopic base material. Thus, the image on the fluoroscopic substrate disposed on or in front is made to appear more clearly.

  The present invention according to claim 11 is the multi-image display method according to claim 10, wherein the semi-transparent filter without the image is a transparent film on which a net pattern, a dot pattern, or a line pattern for reducing transparency is formed. This is a multi-image display method characterized by the above.

  According to the eleventh aspect of the present invention, a net pattern, dot pattern, or line pattern is formed by a technique such as printing with a thin ink film thickness so as to have the same light shielding performance as a completely opaque mesh base material. It is difficult. However, if a net pattern is formed with printing ink, the effect of making the image on the translucent material difficult to see when not lit or when shielding light is obtained.

  In the present invention according to claim 11, one of the advantages over insertion of a mesh substrate without an image or a translucent substrate without an image is that the density or density of a net pattern, a dot pattern, or a line pattern can be changed. That is. When a mesh base material or a translucent base material is partially inserted, the base material end face is easily recognized at the boundary between where the mesh base material and the translucent base material exist. On the other hand, in the case of a net pattern, a dot pattern, or a line pattern formed with printing ink, an intermediate density of 50% can be easily expressed as 0% or 100%. Furthermore, if gradation expression is taken, the density difference boundary line cannot be visually recognized.

  The second advantage is that the shape and density of the net pattern, dot pattern, or line pattern can be changed according to the color, density, and shape in the image. For the portion where it is desired to make the image on the translucent material more difficult to see, the pattern density may be increased. If changing the color has the effect of making the image on the translucent material more difficult to see, the color of the pattern can also be changed.

  According to the twelfth aspect of the present invention, the mesh material or semi-translucent material having no image, or various patterns for lowering the transparency may be a color with saturation, but these are a plurality of images. Change the hue of. On the other hand, by setting these to achromatic colors, the hue does not change only by reducing the lightness. Furthermore, by using a metallic glossy color, the mesh or semi-transparent material with no image or various patterns for reducing the transparency can be reflected, making the image on the translucent material more difficult to see. Can do. The net pattern, dot pattern, or line pattern can be formed of a transfer foil or an etching metal film.

  The present invention according to claim 13 is the multiple image display method according to any one of claims 1 to 12, wherein a mesh material or a semi-transparent material without an image is arranged on the front side of the fluoroscopic base material, In the multi-image display method, the second image (back image) can be clearly seen even when the ambient illuminance is high when the light source is turned on or when light from the light source is opened.

  According to the thirteenth aspect of the present invention, the mesh material or the semi-translucent material is disposed on or in front of the image on the fluoroscopic substrate, so that the translucent material that is difficult to see in a place where the ambient illuminance is high even when the light is applied The upper image can be seen more clearly. This is because the arrangement of the mesh material or the semi-transparent material causes the image of the transparent base material to be shaded, thereby facilitating the recognition of the image of the translucent material. On the other hand, when the light source is not turned on or when the light from the light source is shielded, the image on the fluoroscopic substrate is slightly difficult to see, but the visible light transmittance is in the range of 40% or more and the mesh substrate or translucent If a base material is selected, a range that does not have a problem in recognition can be obtained as a whole. In addition, it is preferable that the mesh base material or semi-transparent base material without an image is an achromatic color.

Since an interference image such as a morphing expression in which one image changes from switching to a different one can be displayed, a device with a high degree of attention can be provided. An expensive mechanical drive device can be omitted, and it is thinner and lighter than a conventional device that moves one large image. Each member becomes inexpensive. Replacing work for attaching and detaching the translucent material or fluoroscopic substrate on which the image is drawn can be simplified and shortened. Even in the morphing expression, a special lens sheet necessary for image switching in the lenticular system or an image driving device required when the viewer does not move is unnecessary. Furthermore, if a thin planar light emitter such as an EL film is used as the light source, the thickness becomes very thin and load resistance is enhanced even when three or two members are stacked. For this reason, if it is used as a floor covering for a floor advertisement, a high degree of attention can be collected. Moreover, since these members can be bent, it is needless to say that they can be installed on the cylinder side surface, the vehicle exterior surface, and the window glass surface. In addition, it is possible to use three types of members without hanging them in the storage (frame) or hanging them.

  According to the fourth aspect of the present invention, an openable / closable shielding member is provided, which irradiates and shields light from the light source. Therefore, there is an advantage that a fluorescent lamp can be adopted as the light source. Therefore, the present invention can be applied to existing fluorescent lamp light source type lighting boards that are already installed in the market. Moreover, a light source such as a phosphorescent material that cannot blink can be used as the light source.

  According to the fifth aspect of the present invention, the partial image on the fluoroscopic base material that is desired to be displayed even when the light from the light source hits the translucent material is drawn on the base material having a light shielding property, and this is drawn on the fluoroscopic base material (hole Since the partial image is made less susceptible to light coming out of a large number of holes or striped fluoroscopic parts by attaching it to an opening material, slit material, or translucent material (translucent material), the following effects are obtained. It is done. The image drawn on the fluoroscopic base material becomes difficult to see when light hits the translucent material due to the influence of light coming out of a large number of holes and striped fluoroscopic parts. Or it looks thin. However, if a part of the image drawn on the fluoroscopic base material is drawn on the base material having light-shielding properties and pasted on the fluoroscopic base material, it can be seen even when the light source is turned on. Thereby, the calm appearance of the deep shadow of the partial image obtained by the light around the installation location is maintained, and an entire image representation having a wide density region with the background of the electric decoration image on the translucent material is obtained. The partial image with the background of the illumination image can also give perspective to the viewer. Further, if the brightness of light hitting the translucent material is reduced, only the partial image portion can be viewed as a complete image in the interference image. The partial image portion can be formed on a commercially available inexpensive printing substrate, not a special material with holes.

According to the invention of claim 6, by allowing the translucent material on which the back image is formed to be scrollable, the range of expression of the multi-image display method of the present invention is widened, and various contents and narrative properties can be provided. That is, by scrolling the light-transmitting material on which the back image is formed while the light source is turned on or when the light is released, not only the images formed on the light-transmitting material are sequentially displayed, but also the light as described in claim 5 is emitted. If a partial image that can be seen even from behind is arranged, the scroll image can be used as the background. For example, in the case of an image in which the scenery can be seen from the car window, it is possible to provide a feeling like riding on a train by scrolling through the scenery image seen from the window, with the car window and the person being always fixed as partial images. . If the scenery is stopped, the train stops, and if the light intensity is reduced, an interference image between the image of the car window portion on the fluoroscopic substrate and the stop image on the translucent material can be seen. Here, if the light source is turned off or the light is blocked, a complete image of the vehicle window portion on the fluoroscopic base material can be seen. If this is an image inside the station, it can be seen as if the train is stopped at the station. On the other hand, if the car window part on the fluoroscopic base material is formed in a dark shade, scrolling the daytime landscape image at the maximum illuminance results in movement of the daytime landscape, but the light intensity is slightly reduced and scrolled. For example, if you move the evening landscape, and if you reduce the intensity of light, you can express the movement of the evening landscape.
As another example, let us give an example of a jet flying. If the ground image seen from the sky that is the background is formed on the translucent material and scrolled, the jet aircraft arranged as a partial image on the fluoroscopic substrate will be in the direction opposite to the scroll direction. Looks like you are moving to. In addition, an example in which an image appears to flow in a direction perpendicular to the scroll direction when scrolling by forming a repeated diagonal line pattern can be seen in a barber symbol, a rotating sign pole, and the like. If a jet image is left in the front image with a similar diagonal line pattern as a background, the jet appears to move in a direction perpendicular to the scroll direction.

  According to the seventh aspect of the present invention, the partial light of the light source that hits the translucent material can be scrolled, so that the range of expression of the multi-image display method of the present invention is widened, and diversity can be given to movement. That is, the light from the light source partially hits the translucent material, and the partial light is scrolled so that the images formed on the translucent material are flown one after another. By disposing a partial image that can be visually recognized even when the light as described above hits from behind, the partial image can be seen to move in the direction opposite to the partial light scroll direction.

  According to the eighth aspect of the present invention, the scrolling of the partial light hitting the light transmissive material is performed by the scroll of the light shielding material placed between the light transmissive material and the light source, so that the method is greatly compared with the method of controlling the light source. Cost can be reduced. The degree of freedom is not as high as the program control of the light source, but to change the shape of the partial light, it is only necessary to change the shape of the light transmission aperture of the light shielding material. The light transmission port of the light shielding material is formed with a hole or a transparent material. A number of holes or slits may be provided in the light-shielding portion to produce the same effect as that of the light source.

  According to the invention of claim 9, by allowing the fluoroscopic substrate on which the back image is formed to be scrollable, the range of expression of the multi-image display method of the present invention is widened, and various contents and narrative properties can be provided. That is, not only the front images formed on the fluoroscopic base material are sequentially displayed, but also a partial image that can be visually recognized even when the light hits from behind is arranged, and the light source is turned on or the light is opened. If the fluoroscopic substrate is scrolled, the partial image can be moved with the back image as the background. For example, in an image example in which a landscape can be seen from a car window, a landscape image that can be seen from the window is a fixed image as a partial image that moves between the car window and a person. It can provide the feeling that the train passes. If this is one kind of story expression, the number of story types that give a sense of movement can be increased by alternately scrolling and stopping the partial table image and the landscape back image. The interference image expression with the light intensity reduced, the image change width by turning off the light source or blocking the light, and the like are the same as the effect of the invention described in claim 7.

  A combination example with a partial light scroll is also given. The scenery seen from the car window, which is the front image, is darkened as a night view. If a completely open surface of the scrollable partial light shielding material to be inserted in front of the light source is selected and light passes through, a vehicle window (front partial image) with the back image of the translucent material as a background can be seen. If the translucent material back image is a blue sky scenery, it can give a feeling of train movement in the daytime. Next, if you continue to scroll the back image of the translucent material and turn on and off the light source while scrolling the partial light-shielding material with a lightning pattern a little late, the train will pass through the night scene where lightning falls. It appears to be moving.

  According to the invention of claim 10, since the translucent filter (mesh material or translucent material) on which no image is drawn is inserted between the fluoroscopic base material and the translucent material, the following effects are obtained. That is, the semi-transparent filter without an image inserted between the upper and lower substrates restricts the appearance of the lower image and weakens the interference between the two images. For this reason, the degree of freedom of color and shade combination of a set of images is widened, and the restriction on the installation location of a plurality of images is reduced. In addition, it is possible to use a fluoroscopic base material having a large aperture ratio of the fluoroscopic part of the fluoroscopic member. For example, since the second image can be easily seen when the aperture ratio is 50%, the aperture ratio needs to be about 40%. However, by inserting such a base material, it can be used even if the aperture ratio is 50%.

  According to the eleventh aspect of the present invention, the transparent film is designed so as to reduce the transparency and weaken the interference between the upper and lower images, so that the lower image can be seen according to the partial image for each location. Can be restricted at different levels. In addition, the border between the portions where the patterns with different densities touch each other can be made inconspicuous, and the degree of freedom in combining colors and shades of a set of images is further expanded. Furthermore, if a pattern is drawn on a transparent or translucent substrate, a cheap and easy-to-handle substrate can be obtained.

  According to the twelfth aspect of the present invention, since the pattern drawn on the mesh base material, the semi-transparent material or the transparent film having no image has a metallic luster, the second image can be made more difficult to see.

  According to the invention of claim 13, since the mesh base material or the semi-transparent material without an image is disposed on the front side of the transparent base material, the image of the transparent base material appears to be shaded. You can make the image more visible. For this reason, even if it installs in the place where ambient illumination intensity is high, the image on the translucent material at the time of light source lighting can be shown clearly. Thereby, the installation possible environment range of the multiple image display object of this invention can be expanded. Moreover, it can be used also in a time zone with high illuminance such as daytime.

  According to the invention of claim 14, the light-transmitting material on which the front image and the back image are formed, or the two image sheet sets of the transparent base material on which the front image is formed and the light-transmitting material on which the back image is formed, It is compact and can be easily carried by storing it together. The positional relationship of images is also maintained. In addition, a device that can switch various images only with a blinking circuit of a light source and a light control device that can adjust brightness is useful at a low cost.

  According to the fifteenth aspect of the present invention, even if the light source is continuously lit, the multi-image expression of the present invention can be realized by the existing electric display by disposing the openable / closable shielding material in front of the light source. It is useful because it can replace the blinking circuit of the light source and the light control device for adjusting the brightness.

  According to the invention of claim 16, since the back image becomes a long material that can be scrolled, various image types can be prepared as the back image, and the back image is scrolled with respect to the fluoroscopic substrate on which the front image is formed. This enables a wide range of expression between the front and back images.

  According to the invention of claim 17, in the multiple image display device according to any one of claims 14 to 16, the partial light of the light source that hits the light-transmitting material can be scrolled so that it can be widened between front and back images. Allows expression.

  According to an eighteenth aspect of the present invention, in the multiple image display device according to any one of the fourteenth to seventeenth aspects, the fluoroscopic substrate on which the first image (front image) is formed, and the second image (back side) In the case of using two image sheet sets in which the translucent material on which the image is formed is arranged on the rear side, a wide expression can be made between the front and back images by scrolling the fluoroscopic substrate.

BEST MODE FOR CARRYING OUT THE INVENTION

  Next, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows two image sheet sets of a first image (front image) sheet and a second image (back image) sheet in the first embodiment of the present invention (the inventions of claims 1 to 3). It is a disassembled perspective view explaining the structure of the example of the multiple image display apparatus which installed A. FIG. 2 is a side view of an image sheet and a light source in the case of claim 2 in the multiple image display device of FIG. FIG. 3 is a side view for explaining an image sheet configuration for displaying a plurality of images in which a first image (front image) and a second image (back image) used in the present invention are formed on one sheet.

  In the multi-image display device, when a light source (fluorescent lamp, halogen lamp, etc.) other than the surface light source is used, the transparent base material 4 and the transparent material 3 can be formed into a cylindrical shape or a conical shape.

  As shown in FIG. 1, the multi-image display device has a frame 1, and an advertisement and a light source are accommodated between the frame 1 and the transparent cover 5. The advertisement is composed of a light-transmitting material 3 and a transparent base material (slit material) 4 in which a large number of circular holes 4a are opened, which are stacked in order from the frame 1 side, below (the frame 1 side). A light source 2 that can blink is inserted. As shown in FIG. 2, the first image P1 (front image) is drawn on the surface of the fluoroscopic substrate 4, and the second image PA (back image) is formed on either the front or back side of the translucent material. However, in this example, it is drawn on a more preferable back surface in combination with a translucent translucent material. The see-through substrate 4 may be a substrate in which a large number of slits are opened instead of holes. The translucent material 3 is a transparent or translucent substrate.

  When the light source 2 is not lit, a front image P1 drawn on the fluoroscopic substrate 4 is visible. When the light source 2 is turned on, light is emitted from the light source 2 through the hole 4a of the light-transmitting material 3 and the transparent base material 4 as shown by a one-dot chain line in FIG. For this reason, the front side of the fluoroscopic base material 4 becomes a shadow, and only a dark color is visually reflected. Then, as shown by a broken line in FIG. 2, the back image PA drawn on the translucent material 3 can be seen through the hole 4 a of the fluoroscopic substrate 4. Thus, by blinking the light source 2, two types of images can be displayed instantaneously. The blinking interval of the light source 2 varies depending on the content of the image, but is selected within a range where the front image P1 and the back image PA can be seen continuously. Generally, 0.25 to 10 seconds are preferable.

  Further, if the luminance is adjusted when the light source 2 is turned on, an interference image between the front image P1 drawn on the fluoroscopic base material 4 and the back image PA drawn on the translucent material 3 can be observed. That is, the back image PA can be seen at the maximum brightness, but the front image P1 gradually appears as the brightness is lowered. Although it differs depending on the opening degree of the fluoroscopic substrate 4 and the light source, when the brightness falls below a certain level, it is completely switched and only the front image P1 can be visually recognized. It is possible to entertain morphing changes in which a person image gradually changes to a wolf image.

  The image sheet shown in FIG. 3 is obtained by forming the functions of the translucent material 3 and the see-through base material (slit material) 4 shown in FIG. 1 on a single sheet. In this example, the functions of the large number of circular holes 4a through which light passes are substituted by a non-image portion and a light-transmitting material. An opaque first image P1 (front image) consisting of three layers is formed on one surface of the translucent material 3. The three-layer configuration includes an uppermost image layer P1a, an intermediate white layer P1b, and a lowermost light-shielding dark color layer P1c. The light-shielding dark color layer P <b> 1 c is in close contact with the surface of the translucent material 3. On the other surface of the translucent material 3, a second image PA (back image) is formed as a mirror image inverted. The range of the aperture ratio of the opening is approximately 25% to 70%. A desirable range is 30% to 50%. As the base material of the translucent material 3, a milky white translucent base material, a white coat transparent base material, a transparent base material, or the like can be used. When the white layer P1b has sufficient light shielding properties, the lowermost light shielding dark color layer P1c can be omitted. When the light source 2 is not lit, a table image P1 drawn on the surface of the translucent material 3 can be seen. During lighting, light is emitted from the light source 2 through the hole 4a of the translucent material 3 as shown by a one-dot chain line in FIG. Come. For this reason, the front side becomes a shadow, and only a dark color appears in the sight. Then, as shown by the broken line in FIG. 3, the back image PA drawn on the light transmissive material 3 can be seen through the hole 4a.

  FIG. 4 is a side view for explaining a multi-image display apparatus according to a second embodiment (invention of claim 4) of the present invention. FIG. 5 is a side view illustrating multiple image display using an openable / closable shielding material in which a plurality of slit-containing porous materials are stacked as the shutter of FIG.

  The multi-image display apparatus of this example has substantially the same configuration as the multi-image display apparatus of FIG. 1, but is different in that a light source other than a light source that is easy to blink is used as the light source 2. Examples of the light source other than the light source that easily blinks include a light source such as a phosphorescent material that cannot blink, and a fluorescent lamp that is slow in blinking or has a remarkable shortening of life due to blinking.

  In the example of FIG. 4, an openable / closable shutter 6 (openable / closable shielding material) is provided between the light source 2 and the translucent material 3. The shutter 6 includes, for example, a large number of elongated shielding pieces 7 that can be opened and closed. By opening and closing the shutter 6, the light can be repeatedly turned on and off even when the light source 2 that is continuously lit is used. Since such a shielding piece 7 has a small moving stroke, it can be switched at high speed. The shape of the shielding piece 7 is not limited to an elongated shape, and it may be such that small pieces such as fish scales are arranged side by side. If the opening of the shielding piece 7 is adjusted, the amount of light passing therethrough is adjusted, and the electrical dimmer can be omitted. The problem that the shadow of the shielding piece 7 hits the translucent material 3 depending on how it is opened is that the number of shielding pieces 7 is increased to narrow the width of one piece (for example, 6 pieces in the figure are changed to 8 pieces) This can be solved by increasing the distance from the material 3.

In the example of FIG. 5, the openable / closable shutter 6 (open / close type shielding material) of FIG. 4 is configured by stacking three (6a, 6b, 6c) porous substrates with light-shielding multi-row slits. That is, if the three pieces are moved relative to each other and the respective slit open portions are covered with the shielding portions, the light can be blocked. If the three shielding portions are completely overlapped, the maximum amount of light can be transmitted from the slits.
Since the moving stroke is small, high-speed switching is possible. If the overlapping amount of the shielding portion 13 is adjusted, the amount of light passing therethrough can be adjusted and the effect of omitting the electric dimmer is the same. The solution to the problem that the shadow of the shielding portion hits the light-transmitting material 3 by adjusting the opening is the same as the shutter 6 of FIG.
The light-blocking multi-row slit porous substrate placed in front of the light source in a plurality of layers is preferably thin so as not to leak light. Since a property that does not collapse is required, a transparent film in which a light shielding portion is formed of a metal thin film such as aluminum is suitable.
When the shutter 6 is composed of two films, the light shielding layers of the slit porous base materials (6a, 6c) are used facing each other. In the case of three sheets, as shown in the figure, 6b added in the middle may form a shielding layer on one side, but it is advantageous for light diffraction to form a shielding layer on both sides.

  FIG. 6 is a side view for explaining a multi-image display method according to the third embodiment of the present invention (the invention of claim 5). The multi-image display device of this example has the same configuration as the device of FIG. 1, but a part of the image P1 drawn on the fluoroscopic base material 4 regardless of whether or not light strikes the translucent material. (Partial image) This is for displaying P10 at all times. In other words, it is for displaying a partial image (partial image) of the image PA when the light hits the translucent material. FIG. 7 is a side view for explaining a method for obtaining the invention effect of claim 5 using the image sheet shown in FIG.

In the example of FIG. 6 using two image sheet sets consisting of a front image and a back image,
The partial image P10 is drawn on a light-shielding base material 15 different from the fluoroscopic base material 4, and the base material 15 is attached to the front or back of the fluoroscopic base material 4 at the position of the partial image P10 via an adhesive. When light does not strike the translucent material, an image P1 drawn on the fluoroscopic base material 4 and a partial image P10 on the base material 15 can be seen. And even if light strikes, since the base material 15 has light-shielding property, the light of a light source does not pass and the image P10 on the base material 15 can be seen. Therefore, when the light hits the translucent material, the image P10 can be seen together with the image PA on the translucent material 3. Note that a dark solid image having the same shape as that of the partial image P10 may be attached to the back surface of the transparent base material 4 at the position of the partial image P10, or to the front surface or the back surface of the translucent material 3. Further, the partial image P10 in the image of the translucent material 3 may be painted in a dark solid color.

  Even in the case of using one image sheet on which a front image and a back image are formed, the partial image P10 is drawn on the light-shielding base material 15, and the base material 15 is attached to the front surface of the partial image P10 via an adhesive. Or by pasting a solid image similar to the partial image P10 behind the position of the partial image P10, the image P10 on the base material 15 together with the image PA on the translucent material 3 when the light source is turned on. You can see the same.

  The example of FIG. 7 is a side view for explaining another method of obtaining the invention effect of claim 5 in the case of using one image sheet on which a front image and a back image are formed. Instead of attaching the light-shielding base material 15, only the partial image P10 is formed without holes during image formation. That is, only the partial image P10 portion is formed with three layers with the complete image (FIG. 7B), or the light-shielding dark color layer P10c, which is the lowest layer of the three layers, is formed with only the partial image P10 portion with the complete image (FIG. 7A). The three layers of the partial image include an uppermost partial image layer P10a, an intermediate white layer P10b, and a lowermost light-shielding dark color layer P10c. When the light does not hit the translucent material, the image P1 and the partial image P10 drawn on the translucent material 3 can be seen. And even if it hits light, since the lowermost light shielding dark color layer P10c has a light-shielding property, the light of a light source does not pass and the image P10 on the translucent material 3 can be seen. Therefore, when the light source is turned on, the image P10 can be seen together with the image PA on the translucent material 3.

  FIG. 8 is a side view for explaining a multi-image display device in which a translucent material according to a fourth embodiment (invention of claim 6) of the present invention can be scrolled. The multi-image display device of this example is for enabling the translucent material 3 on which the image P1 is drawn to be scrolled up and down.

  This multi-image display device has a frame 1 in which advertisements and light sources are stored, a transparent base material 4 protected by a transparent cover 5 on the front side, and a light guide plate 2b in which LED lamps 2a are arranged at both upper and lower ends. The light source 2 which consists of these, and the translucent translucent material 3 in the middle of these are accommodated. The light transmitting material 3 is scrolled by a motor connected to the upper and lower winding / unwinding rollers 7. In this example, the long translucent material is taken up, unwound and scrolled. However, the translucent material may be coupled on the loop and rotated. When the light does not hit the translucent material, the image P1 and the partial image P10 drawn on the fluoroscopic base material 4 can be seen. When the light hits, the image P10 can be seen with the image PA on the translucent material 3 as the background. . Therefore, if the image PA on the translucent material 3 is scrolled when the light source is turned on. The image P10 appears to move in the opposite direction.

  FIG. 9 is a side view for explaining a multi-image display device capable of scrolling partial light of a light source corresponding to a light transmissive material according to a fifth embodiment (inventions of claims 7 and 8) of the present invention. In the multi-image display device of this example, the partial light is scrolled by scrolling the partial light shielding material 10 having an opening.

In this multi-image display device, a transparent cover 5, a transparent base material 4, and a translucent material 3 are set on the image installation portion of the frame 1 in order from the front side, and a partially light-shielding material 10 that can be scrolled to the rear thereof. The light source 2 (the light guide plate 2b in which the LED lamps 2a are arranged at both upper and lower ends) is accommodated at the end.
The opening part of the partial light shielding material 10 can take various shapes such as a square, a circle, and a star. The scrolling is performed by a motor connected to the upper and lower winding / unwinding rollers 7. In this example, the long partial light shielding material is taken up and unwound to scroll the partial light from the light source. However, the partial light shielding material may be combined and rotated on the loop.

  When the light does not hit the translucent material, the image P1 and the partial image P10 drawn on the fluoroscopic base material 4 can be seen, and when the light hits, the part of the partial light shielding material 10 is unwound. If it is stopped and matched with the image PA on the translucent material 3, the image P10 can be seen with the image PA as the background (FIG. 9A). Next, if the partial light shielding material 10 starts scrolling and moves in a shape that partially transmits light, the image P10 appears to move in the opposite direction (FIG. 9B).

  FIG. 10 is a side view for explaining a multi-image display device capable of scrolling a fluoroscopic substrate according to a sixth embodiment (invention of claim 9) of the present invention. The multi-image display device of this example is for enabling the fluoroscopic substrate 4 on which the image P1 is formed to be scrolled up and down.

In the multi-image display device, a transparent cover 5 that protects an image is fixed to the front side of the frame 1,
On the rear side, a scrollable transparent base material 4 on which a large number of front images P1 are formed is arranged, and on the rear side, a translucent material 3 on which a back image PA is formed is arranged. A light guide plate 2b) in which LED lamps 2a are arranged at both upper and lower ends is housed. The fluoroscopic substrate 4 is scrolled by a motor connected to the upper and lower winding and unwinding rollers 7. In this example, the fluoroscopic base material 4 is taken up, unwound and scrolled. However, the fluoroscopic base material 4 may be coupled and rotated on a loop.

  If the transparent base material 4 is scrolled when no light is applied to the translucent material, the front image P1 can be sequentially displayed. When the light is applied, the front image P1 becomes invisible, but the image PA on the translucent material 3 is displayed in the background. The partial image P10 on the fluoroscopic substrate 4 can be moved.

In the above description, the holes (slits, see-through portions) of the fluoroscopic base material have many holes or multi-row rectangular holes penetrating therethrough. However, a transparent base material that is printed on a transparent film so that a large number of circular portions and slit portions remain transparent may be used. In any case, the range of the aperture ratio of the hole (slit, see-through portion) is approximately 25% to 70%. A desirable range is 30% to 50%.
Further, in the apparatus for displaying two types of images shown in FIG. 1, the back side of the transparent base material may be provided with adhesiveness and attached to a transparent material (translucent base material).

  As the translucent material, a translucent or transparent resin film such as polyester or vinyl can be used. When the brightness of the light source arranged on the lower side is low, the appearance of the image on the transparent material is weakened. Therefore, it is preferable to use a transparent resin film. If the light source is sufficiently bright, a translucent resin film can also be used. The thickness range is generally 20 to 500 μm, and the desirable thickness range is 25 to 200 μm.

  As the surface light source, it is possible to use a lineup of multiple fluorescent lamps, a light guide plate that spreads LED light over the entire emission surface, a flat light emitting surface with optical fibers arranged, and a plasma display, but the thickness, price, weight, and usage range In view of the above, an EL light-emitting film having an emission value of 800 to 3000 lux or an LED light guide plate of 1500 lux or more is preferable. When using the shutter shown in Fig. 2, various light sources such as fluorescent lamps, non-flashing lamps, fluorescent lamps, phosphor light sources, incandescent lamps, halogen lamps, arc discharge lamps including mercury lamps can be used. Become.

  In the case of a device that displays two types of images, the fluoroscopic base material, the translucent material, and the light source do not necessarily need to be in close contact with each other. Even if there is a space between each member, the effect of the present invention can be obtained. Therefore, the member may not be housed in a frame, and may be hung in a short-distance space, for example. Accordingly, a transparent glass plate or resin plate may be interposed between the members for the purpose of preventing wear.

  Such a member to be inserted for various purposes (image quality improvement, wear prevention) between the transparent base material and the light transmitting material or between the light transmitting material and the light source will be described.

  FIG. 11 is a side view illustrating a multiple image display device according to claims 10 to 13. In this example, a mesh material or translucent material 11 is inserted between the see-through substrate 4 and the translucent material 3.

  When the light source is not turned on, the image PA drawn on the translucent material 3 may be seen from the hole 4a of the fluoroscopic base material 4 and interfere with the image P1 drawn on the fluoroscopic base material 4 and may be difficult to see. In such a case, when a translucent filter (mesh material or translucent material) 11 is inserted between the see-through substrate 4 and the translucent material 3, the image PA on the translucent material 3 becomes difficult to see. The image 4a on the material looks clear.

  The translucent filter 11 is preferably an achromatic color, and more preferably an achromatic color having a metallic luster. When a transparent or translucent substrate having a net pattern, dot pattern or line pattern is used as the translucent filter 11, it is preferable to form an achromatic pattern having a metallic luster by a method such as foil transfer. The mesh material is a thin metal wire or fiber knitted in a lattice shape. Since the metal wire has a light shielding property, the effect of making the image PA on the light transmitting material 3 difficult to see is high.

The net pattern is a lattice pattern composed of lines intersecting in the vertical direction and the horizontal direction. The dot pattern is a dot pattern such as a halftone dot in various printing methods, and the shape is not limited to a circle or a quadrangle. An example of a line pattern is a grain pattern in a printing method halftone dot. In the case of inkjet printing, a grain pattern by an error diffusion method is well known. The fineness of the halftone dots to be employed is affected by the accuracy of the porous pitch formed on the fluoroscopic substrate. As the porous pitch accuracy increases, the fineness of the halftone dots also needs to be increased. When a general one-way vision film is used, the hole diameter is about 1.5 mm to 2 mm and the porous pitch is about 2 mm to 3 mm. In this case, fineness of about 1 to 10 lines or 20 lines can be sufficiently used for each pattern.
The fineness of the halftone dots is not too high and does not become a big problem.

  Furthermore, since the transparent or translucent base material on which the pattern is formed can change the density or density of the pattern, there is an advantage over the mesh material or the translucent material as described below. When a mesh material or a translucent material is partially inserted, the end surfaces of these inserted materials are easily recognized at the boundary between the portion where these mesh materials and the semi-transparent material do not exist. On the other hand, in the case of a transparent or translucent substrate on which a pattern is formed, the boundary can be blurred by taking an intermediate density, so that the pattern breaks cannot be visually recognized. Moreover, if a metal foil pattern is formed by a method such as transfer, an insert having a metallic luster that is easier to handle than a wire mesh or the like can be obtained.

  Furthermore, the shape and density of the pattern can be changed according to the color, density and shape of the image. In order to make the image on the translucent material more difficult to see, the density of the pattern corresponding to the portion of the image may be increased. If changing the color has the effect of making the image on the translucent material less visible, change the color of the pattern.

  Moreover, as shown by the imaginary line of FIG. 11, another mesh material or translucent material 12 can also be arrange | positioned ahead of the fluoroscopic base material 4 (invention based on Claim 13). The mesh material or translucent material 12 is preferably achromatic. In places where the surrounding illuminance is high, an image on the translucent material 3 may be difficult to see when the light source is turned on. Therefore, when the mesh material or the translucent material 12 is arranged in front of the transparent base material 4, the table image P1 on the transparent base material 4 is placed in a shaded place, and the light-transmitting material 3 is turned on when turned on. This is because it becomes easier to see the back image PA. When the light source is not turned on, the image on the fluoroscopic substrate 4 is slightly difficult to see, but the opening degree of the mesh material and the concentration of the semi-translucent material may be selected to such an extent that the image can be seen.

Next, specific examples of the present invention will be described.

Example 1
A transparent base material was prepared by printing a front image on a paper one-way vision sheet “PanoRamaVision” (trademark, manufactured by Continental Grafix) having a hole diameter of 1.5 mm and an aperture ratio of 50% by inkjet. In addition, a transparent image was printed on a transparent polyester film “Kimoart series / transparent PET” (trademark, manufactured by Kimoto Co., Ltd.) having a thickness of 100 μm by inkjet to prepare a translucent material. A translucent material was placed below the fluoroscopic base material, and an EL sheet “FlexLit” (trademark, manufactured by MASCOT TECHNOLOGY) having a thickness of 0.6 mm and a brightness of 1000 lux was laid below the translucent material. These were stored in a floor advertisement protection rug “Floor Wind” (trademark, manufactured by FloorWind International). When the EL sheet was turned off, the front image on the one-way vision sheet was seen, and when turned on, the back image on the transparent polyester film was seen. Next, when the brightness of the EL sheet was lowered to 600 to 700 lux using a light control device, the front image appeared, and at 300 to 400 lux, the back image became stronger.

(Example 2)
Using a super wide format printer VUTEK QS2000 (trademark, manufactured by EF Corporation) equipped with UV curable pigment ink, a transparent polyester film “PET white coat” (trademark, manufactured by Sanryu Corporation) with a thickness of 188 μm, Three films of 188 μm thick milk white polyester film “U298W” (trademark, manufactured by Teijin DuPont Films) and 188 μm thick transparent polyester film “PET white coat” (trademark, manufactured by Sanryu Co., Ltd.) with white coating on one side A front image was formed by inkjet printing. The PET white coat formed a front image on the side on which the white coating was applied. A table image consisting of three layers of a white layer and an image layer on a dark color layer that has been improved by adding three colors of CMY to black has a porous opening with a hole diameter of 1 mm and an aperture ratio of 40%. Let On the opposite side (back side) from the front image forming side, a reverse back image without a porous opening was formed by sublimation transfer printing. The sublimation transfer print image is obtained by mounting a sublimation ink “HANAE-D type” (trademark, manufactured by Sanryu Co., Ltd.) on a JV-4 printer (trademark, manufactured by Mimaki Engineering Co., Ltd.), and transfer paper “HTR-4000” (trademark, Coldenhove). It was formed by printing at 180 ° C. for 2 minutes under a thermal transfer condition. The completed image sheet was inserted into an LED light panel “B1-LED-W” (trademark, manufactured by Lumi Techno Co., Ltd.) having a brightness of 2200 lux to confirm the appearance of the image. When the LED panel was turned off, a front image was visible. Only the front image of the transparent polyester film looked unsightly due to the interference of the reverse image on the back side. The milk white polyester film was thick, and the transferred penetrating image was not clearly visible up to the front image side (the opposite side of the transfer), so the interference between the front and back images was not noticeable. On the other hand, a polyester film coated with a white coating has a transfer penetrating image formed on a transparent layer, and therefore cannot be seen through the white coating when the light is extinguished. The interference between the front and back images was the least. When the LED panel was turned on, the back image was seen as an electrical decoration image. All three films were deep and vivid.

(Example 3)
Using the fluoroscopic base material and the translucent material prepared in Example 1, the appearance of the front image on the fluoroscopic base material when the EL sheet was not lit was checked. In the dark part of the front image on the fluoroscopic substrate, the back image on the translucent material was seen through the hole of the fluoroscopic substrate and the image interfered. Therefore, a white or black polyester high-density mesh cloth “Cross Cabin” (trademark, manufactured by Teijin Nestex) with a mesh size of 80 microns and a transparency of about 60% was inserted between the transparent base material and the transparent material. . Then, it became difficult to see the back image, and the image interference was greatly improved. The black mesh cloth has a greater effect of hiding the back image than the white mesh cloth, but the white mesh cloth hardly decreased the illuminance when the EL sheet was lit, and the back image on the translucent material was easier to see. In this example, the mesh cloth is inserted over the entire surface of the image, but it may be inserted only into a portion where the effect is obtained. Even if a translucent black or milky white film or glass plate is inserted, the same effect as that of mesh cloth insertion can be obtained.

Example 4
The high-density mesh cloth “Cross Cabin” used in Example 3 is a mesh having a mesh size larger than that of the cloth, and a black polyester mesh cloth “Cross Cabin VT” having a mesh space of 600 microns (trademark, manufactured by Teijin Nestex). Replaced. Although the ability to hide the back image is reduced as much as the mesh is large, the effect of making it difficult to see was obtained. Furthermore, instead of this mesh cloth, a stainless steel mesh wire mesh of mesh No. 24 (wire diameter 0.25 mm, aperture ratio 58.6%) and mesh No. 40 (wire diameter 0.18 mm, aperture ratio 51.3%) “ The effect was confirmed by sequentially inserting “Stainless steel 304 plain weave wire mesh” (trademark, manufactured by Netchu Wire Mesh Co., Ltd.). Compared to the mesh cloth, in the case of these metal meshes, the incident light is reflected by the metallic luster of the line visible from the hole of the fluoroscopic base material, so that the concealing effect of the lower image is the greatest. At the same time, it reflects without absorbing light, so the back image also appeared bright when the EL sheet was lit. In order to obtain the same effect as that of a wire mesh, a mesh cloth covered with a metal by a technique such as vapor deposition or sputtering can be used.

(Example 5)
The following sports gym advertisement images were created using the various members used in Example 1. First, as a front image, an image of a body builder holding a dumbbell and lowering his arm was used. As a back image, an image of a body builder lifting a dumbbell was used. When the blinking of the EL sheet light source was set to repeat at 1 second intervals, it seemed that the bodybuilder continued to move up and down the dumbbell.

(Example 6)
With the various members used in Example 1, the following residential advertisement images were created. As a front image, an image depicting a blue sky, the ground, and a house was used. As the back image, we used an image that darkens the back of the same house and lightning falls into the sky. When the EL sheet light source blinks repeatedly at intervals of 1 second and 2 seconds, it became a landscape where a storm came for 1 second after a quiet landscape for 2 seconds, and I felt a story. If the house and the ground portion are arranged on a light-transmitting material in the same manner as the transparent base material, it can be viewed as an electric decoration image. However, the density difference between the lightning thunder is not large and the impact on the viewer is small. Therefore, when a dark solid print image having the same shape as the house and the ground part was pasted on the back image, the house and the ground part on the fluoroscopic substrate were seen when the light source was turned on. This exceeded the density range of the electric decoration image, and the impact on the viewer was slightly increased, but it appeared lighter than the original due to the influence of light transmitted through the black solid print image. Finally, when a sheet with a light-shielding dark paste having the same shape as the house and the ground portion was pasted on the back side of the fluoroscopic substrate, the image on the fluoroscopic substrate was seen at the original deep density when the light source was turned on. With the illuminated image as the background in the distance, the house with a sense of density and the ground part looked closer.

(Example 7)
When the floor advertisement protection rug “floor window” storing a plurality of images and EL sheets prepared in Example 1 was placed on the floor near the window, the illuminance in the vicinity was too high, and it was difficult to see the back image when the EL sheet was lit. Therefore, a 0.5 mm thick smoke color PVC sheet “Uni Sunday” (trademark, manufactured by Kogyo Co., Ltd.) was placed on the fluoroscopic substrate. Although it was a semi-transparent plate with a light brown taste, the effect on the hue was not noticed, and the appearance of the front image was kept sufficiently, and at the same time, the back image was also easily visible when the EL sheet was lit.

(Example 8)
An inner panel with an illuminance of 5000 lux using a fluorescent lamp as the light source was attached to the wall surface. At the front, a blind-fixing headbox is attached to the wall so that the horizontal blind with high light-shielding function “Sereno 25 high-light-shielding type (Hikalist)” (trademark, manufactured by Nichibay) is attached to the wall. Was surrounded by a blackout frame to prevent light from leaking. The same see-through base material and translucent material as in Example 1 were stacked and hung in front of the horizontal blind. Next, the inner illuminating panel was turned on to open and close the slat blades of the horizontal blind. Since only the slat blades with a width of 25 mm were rotated, it was possible to easily perform a high-speed repeated operation at a low load close to the blinking of the light source, and to quickly shield and release the light hitting the entire image. Each time I saw two images switched. In the embodiment, a slat blade opening / closing operation was manually performed by pulling a string using a horizontal blind for a general house as a light shutter device. However, the actual light shutter device is electrically operated and irradiation required by the content of the image is performed. What is necessary is just to perform the opening-and-closing operation according to timing.

Example 9
Various members used in Example 1 and a banner stand “roll poster” (trademark, Environment & Graphic) that rolls a sheet connected in a belt shape in the vertical direction, and an LED light panel “B1-LED-W” ( Using a trademark (manufactured by Lumi Techno Co., Ltd.), scroll confirmation was carried out on three types of base materials: a back image on a translucent material, a partial light shielding material having an opening, and a front image on a fluoroscopic base material.
First, the translucent material sheet was rolled. An LED light panel light source with a transparent base material with a front image formed on the foreground, a rear image formed later, and a translucent material sheet connected in a belt shape hung on a banner stand, with the light emitting part facing the front image side On the inside of the belt. When the light source was not lit, the front image was seen in the foreground, and when turned on, the back image was seen. If the upper motor was turned on while the light source was on and the belt was rolled, the back image moved smoothly. When the motor was turned off with the attached switch, a stop image of the back image could be seen. As a partial image with a light-shielding property in the table image that can be seen when the light source is not lit, if you prepare a jet aircraft anchored at the airfield, when you turn on the light source, the runway will show the ground image seen from the sky where you can see countless small houses It changed to the back image that I drew, and if I started rolling at the same time, the ground eventually changed to the sea level. When the ground image was prepared again around the time of one rotation of the belt and the light source was turned off after the rolling stopped, the jet appeared to have stopped on the runway.

(Example 10)
Next, the light blocking material provided with a circular opening was moved to roll the partial light. A transparent base material with a front image and a translucent material with a back image are installed on the front, and a partial light-shielding material sheet that connects a light-shielding material with a circular opening in a belt shape is hung with a banner stand, and the light-emitting part is imaged Install the LED light panel light source facing the side inside the belt. When a fireworks with a diameter smaller than the circular opening is drawn as the transparent material back image and a dark shade material is pasted on the other part, the night view prepared as the top image on the transparent base material disappears only when the light source is turned on. In other words, except for the fireworks where the light hits, it remains as a partial image to be displayed. The opening on the partial light shielding material is larger than the fireworks and is formed according to the position of the fireworks. If you turn on the light source when you roll and the opening matches the position of the fireworks, you can express the fireworks in the night view. If you continue rolling down, the fireworks will disappear from above. At this time, if the brightness of the LED light itself is gradually reduced, the feeling that fireworks disappear into the night sky can be expressed delicately. Instead of dimming the light source by dimming, if a large number of holes such as screen dots are opened above the opening of the dark shade material and the degree is gradually reduced, the transmitted light will decrease and disappear completely as the rolling progresses. The same effect as dimming can be obtained.

Example 11
In the next example, a fluoroscopic base material having a front image formed on the foremost surface is connected in a belt shape, suspended by a banner stand and scrolled, and an LED light panel on which a translucent material having a back image is set is installed on the rear side. The outer space is drawn as a translucent material back image, and a human or a spaceship wearing a space suit is placed as a partial image on the front image. When the belt-shaped fluoroscopic base material is scrolled when the light source is turned on, a human or a spaceship moves downward (or upward) so as to flow in outer space. When the lights were turned off when the scrolling was stopped, a complete table image with advertising texts suddenly appeared on people and spaceships, which caught my eye. When scrolling resumed, the brightness of the light source was gradually increased to reach the maximum brightness, and then scrolling resumed, and the ad text and its background disappeared into outer space, and I felt like watching a movie scene .

  In Examples 9 to 11, the three types of base materials, that is, the back image on the translucent material, the partial light shielding material having an opening, and the front image on the fluoroscopic base material were scrolled independently. If you do this, you can increase the expression and the effect of increasing attention. In addition, when a translucent material in which a front image and a back image are formed on a single image sheet is scrolled, the front image and the back image cannot be freely replaced, but both images combined with a single scroll drive unit. It is possible to obtain an advantage that the expression can be switched one after another.

  The product of the present invention can display information, advertisements, and other designs that can only be seen from one side by switching multiple images at a single location to increase the attention level and display a lot of information. , Used to enjoy the change. The method and apparatus of the present invention can be used for floors, wall surfaces, pillar side surfaces, independent signboards, partitions, ceilings, vehicle exterior surfaces, window glass surfaces, advertising towers, game machine panel surfaces, accessories, electrical / electronic devices, and the like.
