Description

The present invention relates to a transmissive sign effect system that displays characters or figures by projecting an image or an image.

Conventionally, as an advertising sign for stores, for example, a blinking pattern of light or a video has been used to attract the attention of passers-by. As such a dynamically appealing advertising method, for example, a method of projecting an image on a floor or a screen is known, but as an advertisement in which a passerby can visually recognize such a method from a storefront. When used, there was a problem that it was difficult to secure a place to install the projector.

An example of the background technique of such an advertising method is disclosed in Patent Document 1. The projection device of the background technique is configured to project an advertisement image from a projector 2 installed indoors to a signboard 15 installed on the outer surface or the outer surface of the building B through the image guide tube 4.

However, in the method using a guide tube as in Patent Document 1, it is necessary to process the wall surface in order to pull out the guide tube to the outside, and the appearance of the window made of glass or acrylic is greatly impaired, and installation or removal is performed. There was a problem that the construction was difficult and large-scale. Further, when applied to a so-called window display, there is a problem that a member such as a guide tube is located on the front side of the transmissive surface, and the designability is greatly impaired. Furthermore, when applied to signboards, advertisements, etc., members such as guide pipes are located in front of the signboards, etc., and a part of the signboard (advertisement) is hidden, so that the visibility of the advertisement is reduced and it becomes an advertisement. There was also the problem that the value of was impaired.

In this embodiment, the design of "DA" is applied as the design unit 22. The transmissive sign effect plate 2 in this embodiment has a predetermined thickness, and as shown in FIG. 2, has a smooth one surface (back surface) 24 located on the side where the projector 3 is arranged, and It is a plate-shaped transparent plate having a smooth other surface (surface) 23 facing one surface 24. Further, a milky white glass film is attached to the back surface 24 of the transparent plate in the shape of "DA" to form the design portion 22. That is, the back surface 24 of the transmission portion 21 in this embodiment is a transparent smooth surface formed on the transparent plate. It is preferable that the transmissive sign effect plate 2 has a flat plate shape, and not only the back surface 24 but also the front surface 23 is a smooth surface, and the front surface 23 and the back surface 24 are parallel surfaces (parallel surfaces).

The transmissive portion 21 sandwiches the transmissive sign effect plate 2 so that the viewer viewed from the front surface 23 side can visually recognize the background on the back surface 24 side, and the transmissive unit 21 allows the viewer viewed from the back surface 24 side to see the background on the front surface 23 side. To be visually recognized. The transmissive portion 21 is a part of the transmissive sign effect plate 2. Further, the transmissive portion 21 (outer shell of the transmissive portion 21) preferably occupies an area equal to or larger than the design portion 22 when viewed from the front (when viewed from the back). In this embodiment, almost the entire transmissive sign effect plate 2 excluding the design portion 22 is the transmissive portion 21.

The design portion 22 is provided on the back surface 24, on the front surface 23, and at least one of the space between the back surface 24 and the front surface 23 in the transmissive sign effect plate 2, is translucent, and has a lower light transmittance than the transmissive unit 21. Has. When the design portion 22 is provided on the back surface 24 or the front surface 23, the surface processing or the diffusion transmission sheet may be attached, but when the design portion 22 is provided between the back surface 24 and the front surface 23, a transmission type such as transparent glass is used. It is preferable to provide a portion (a portion that looks white) through which light is diffused and transmitted by laser irradiation or the like inside the sign effect plate 2.

The design unit 22 disperses the light including the image or the image projected from the projector 3 on the back surface 24 of the transmissive sign effect plate 2 in the design unit 22 and transmits it to the surface 23 side, and the surface 23 side. Make it visible from. That is, the design unit 22 functions as a light diffusing unit that diffuses the projected light internally. It is preferable that the design portion 22 is arranged so that the projector 3 is arranged and is detachably arranged on the back surface 24 corresponding to the incident surface. Detachable arrangement may mean that only the design portion 22 is detachably attached from the transmissive sign effect plate 2, or the transparent portion 21 including the design portion 22 can be detachably attached. .. The design portion 22 is preferably formed by being attached to a back surface 24, which is a side on which the projector 3 is arranged, by an adhesive substance such as a seal on a smooth surface. Further, it is preferable that the shape of the design portion 22 has design characteristics such as characters and patterns. The design portion 22 of this embodiment is formed by attaching a milky white glass film in the shape of "DA" to the back surface 24 of the transparent plate constituting the transmissive sign effect plate 2.

As shown in FIG. 3, the design unit 22 is a portion that is arranged in the projectable region 220 and is composed of a diffusion transmission sheet or the like that functions as a light diffusion transmission region 221. Inside the portion, a virtual line is shown in the figure. It has a projection area 222 shown by.

The projectable area 220 is a range in which an image or an image projected by the projector 3 can be projected. The projectable region 220 is set on the transmissive portion 21, and includes at least a part of the transmissive portion 21 and a part of the design portion 22. That is, the design portion 22 is formed in a part or a plurality of parts in the projectable area 220, which is not all. The projectable region 220 preferably includes the design portion 22. The projectable area 220 is set in a range that does not cover the products arranged inside the store, for example, in a show window.

The projection area 222 is a range in which an image or an image projected from the projector 3 is projected. In the present embodiment, the projection region 222 is configured so that its outer shell is contained (enclosed) in the outer shell of the design portion 22 (light diffusion transmission region 221). That is, in this embodiment, the projection region 222 is configured to be one size smaller than the design portion 22 (light diffusion transmission region 221), and the design portion 22 (light diffusion transmission region 221) is one size larger than the projection region 222. It is configured. The inner shell of the projection region 222 (the line forming the blank inside the “DA”) is not particularly limited, but is contained (included) in the inner shell of the light diffusion transmission region 221 as in the present embodiment. It is preferably configured. That is, the projection region 222 is provided in the region of the light diffusion transmission region 221. In other words, the projection region 222 is provided so as to overlap the light diffusion transmission region 221. It should be noted that the term “fitting within the outer shell (inner shell)” as used herein means that the overlapping state (a part or the whole of the outer shell or the inner shell of the projection region 222 is one of the outer shell or the inner shell of the light diffusion transmission region 221). A state that overlaps with a part or the whole) is also included. Further, the projection region 222 may have a shape different from that of the light diffusion transmission region 221. The projection area 222 in this embodiment is a part of the design unit 22. Further, the projection area 222 may be one size larger than the design portion 22. However, the projection area 222 is set so as to be within the projectable area 220 in any case.

Further, the light transmittance of the design portion 22 (light diffusion transmission region 221) is lower than that of the transmission portion 21, and the image or image projected from the projector 3 on the back surface 24 of the transmission type sign effect plate 2 is displayed. It diffuses and permeates the surface 23 so that it can be visually recognized from the surface 23 side. Further, the light transmittance of the design portion 22 (light diffusion transmission region 221) is such that the image or image projected from the projector 3 on the back surface 24 of the transmissive sign effect plate 2 is transmitted to the front surface 23 to the front surface 23 side. It is preferable that the transmitted image or image is not projected on the floor surface, the wall surface, the ceiling, etc., which is an extension line of the projection destination. For evaluation of such light transmittance, for example, total luminous flux transmittance, visible light transmittance, gloss value, and Log haze value can be used. The thickness of the design portion 22 (light diffusion transmission region 221) is preferably 50 to 150 μm.

The total luminous flux transmittance is a ratio indicating how much all the incident light is transmitted in the incident direction. The total luminous flux transmittance of the design portion 22 (light diffusion transmission region 221) is preferably 60 to 98%, more preferably 70 to 95%.

The visible light transmittance is a ratio indicating how much visible light other than ultraviolet rays and infrared rays is transmitted in the incident direction among the incident light. The visible light transmittance of the design portion 22 (light diffusion transmission region 221) is preferably 40 to 95%, more preferably 50 to 90%.

The gloss value is a value indicating the degree of glossiness of the surface of the target, and corresponds to the mirror surface glossiness (gloss value) defined in JIS Z 8741. The gloss value of the design portion 22 (light diffusion transmission region 221) is preferably 2 to 30, and more preferably 3 to 15. As a method for measuring the gloss value, for example, it can be measured using a handy gloss meter (HORIBA IG-320 or the like) as a measuring device.

The Log haze value is expressed using a haze value for evaluating the degree of cloudiness of the object (Log haze = 1285 × lоg [(haze value / 20) +1]). The Log haze value of the design portion 22 (light diffusion transmission region 221) can be 120 to 350, preferably 120 to 300, and more preferably 120 to 200. The unit of these Log haze values is HULog. As a method for measuring the haze value and the Log haze value, for example, a triple-angle gloss meter (Elcometer 408 or the like) can be used as a measuring device for measurement.

Further, among these evaluation values, it is more preferable to set the Log haze value to a preferable range and the visible light transmittance to a preferable range.

The projector 3 is, for example, a projector installed on the ceiling, and projects an image or an image on the projection area 222 of the design unit 22. The projector 3 is connected to a computer (not shown) including, for example, a control unit, a storage unit, and a communication unit by wire or wirelessly, and the computer controls the execution of projection and the content of the video or image to be projected. May be good. In this case, the control unit of the computer projects the video or image stored in the storage unit onto the projection area 222 of the design unit 22, or the video or image received from the outside by the communication unit is projected onto the projection area 222 of the design unit 22. Project to. The projector 3 is the same projection that projects an image or an image having a shape that matches the design shape of the design unit 22, a reduced projection that projects an image or an image that is one size smaller than the design shape of the design unit 22, and the design unit 22. At least one of the magnified projections for projecting an image or an image having a shape one size larger than the design shape of the above is performed.

An example of the trajectory of the projected light is shown in FIGS. 1 and 2 as a projection line 31. The position of the projector 3 is preferably an arrangement in which an image or an image is projected onto the design unit 22 from the upper side to the lower side of the back surface 24 of the design unit 22 or from the lower side to the upper side of the back surface 24. That is, it is preferable that the projection line 31 is arranged so that the ground, the floor surface, and the ceiling (top surface) are located on the extension line from the intersection with the design portion 22. The projector 3 is arranged so as not to overlap with the design portion 22 at least in front view or rear view (a position away from the design portion 22, that is, outside the design portion 22). In other words, the projector 3 is arranged so as to project onto the design unit 22 from a direction having an appropriate angle from a vertical line with respect to the plane of the design unit 22. The appropriate angle can be 10 degrees or more in the range of 80 degrees or less, preferably 20 degrees or more, and more preferably 45 degrees or more. Further, the projector 3 is arranged so as not to overlap the transmissive sign effect plate 2 in front view or rear view (at a position away from the transmissive sign effect plate 2, that is, outside the transmissive sign effect plate 2). Is preferable. Further, the projector 3 is preferably a projector provided with a single focus lens. As a result, even if the projector 3 is installed on the ceiling or floor (or the ground), the distance from the projector 3 to the design unit 22 can be shortened, for example, a short distance in the display space where a mannequin or the like is displayed in a store. It is possible to project a sufficiently appropriate image or image even at a distance.

FIG. 4 is an explanatory diagram of the course of the projected light beam on the transmissive sign effect plate 2.
The projection ray 32 for displaying the image or the image projected from the projector 3 is incident on the projection area 222 of the design unit 22. At this time, the incident projected light 32 is dispersed in the transmitted light 321 that passes through the design portion 22 as it is according to the total light transmittance of the design portion 22 and in the design portion 22 according to the Log haze value of the design portion 22. It is decomposed into the dispersed light 322 and the reflected light 323 that is reflected when it is incident on the design unit 22 according to the gloss value of the design unit 22. However, since the total luminous flux transmittance is evaluated even for invisible light rays, it is the visible light transmittance that affects the actual visual recognition.

That is, the amount of light of the transmitted light ray 321 is smaller than the amount of light of the projected light ray 32, and is controlled (adjusted) and changed by the total luminous flux transmittance, the gloss value, and the Log haze value of the design unit 22. Further, the amount of light of the transmitted light 321 when actually visually recognized is controlled (adjusted) and changed by the visible light transmittance, the gloss value, and the Log haze value of the design unit 22.

Subsequently, the behavior of the image and the image projected from the projector 3 will be described. The image or image projected from the projector 3 is projected onto the projection area 222 of the design unit 22. At this time, the distributed light 322 dispersed in the design unit 22 causes the design unit 22 to emit light according to an image or an image. Therefore, the image or image transmitted through the design portion 22 can be visually recognized from the front surface 23 side, which is not the back surface 24 side on which the projector 3 is arranged. On the other hand, since the amount of transmitted light is smaller than the amount of projected light, no image or image is projected on the surface on the extension line of the projection line 31, or the brightness (brightness) is so low that the image or image cannot be recognized. It is projected.

FIG. 5 is a photograph of an embodiment of the transmissive sign effect system 1, and FIG. 6 is a photograph of a part of the floor surface of the projection destination in the embodiment of FIG.
As shown in FIG. 5, the transmissive sign effect plate 2 of the present embodiment has a transmissive portion 21, a design portion 22, and a projectable region 220 that includes a part of the transmissive portion 21 and the entire design portion 22. .. Further, the design unit 22 has a light diffusion transmission region 221 labeled as “WELCOME TO DAIKAN”. In this embodiment, the design portion 22 is a glass film attached to the back surface 24 of the transmissive sign effect plate 2. Further, the projector 3 projects an image or an image as the projection area 222, which is at least one size larger than the design shape of the design unit 22 “WELCOME TO DAIKAN”.

As a result, as shown in FIG. 6, on the floor surface 225, the design edge light 223 projected along the edge of the "WELCOME TO DAIKAN" of the design unit 22 and the "WELCOME" framed by the design edge light 223. A blank design shadow 224 with a "TO DAIKAN" design is projected. With such a configuration, it is possible to produce an effect such that the design portion 22 having a shining edge is projected onto the floor surface 225. At this time, the design unit 22 projects an image or an image projected from the projector 3 onto the characters "WELCOME TO DAIKAN" and appears to shine.

In Table 1, each material of Examples 1 to 4 and Comparative Examples 1 to 4 is made into a sheet having the same shape, attached to the back surface 24 of the transmission portion 21 as the design portion 22, and the same image is projected from the same projector 3. This is the result of evaluating the transparency of the case. The evaluation of transparency is "○" for "when the image is transmitted so that it can be seen from the surface 23 side and the image is not projected on the surface on the extension line of the projection line 31", and "so that it can be seen from the surface 23 side". When the image is transmitted to the surface and the image is hardly projected on the surface on the extension line of the projection line 31 (it is shining but the image cannot be clearly recognized visually), "△" and "the image from the surface 23 side". "When is not visible" or "when the image is clearly projected on the surface on the extension line of the projection line 31" is defined as "x". In addition, for each Example and Comparative Example, the thickness, Log haze value, specular reflection peak value, gloss value, shielding coefficient, visible light transmittance, and total luminous flux transmittance were measured. A triple-angle gloss meter (Elcometer 408) was used to measure the Log haze value and the specular reflection peak value. A handy gloss meter (HORIBA IG-320) was used to measure the gloss value.

The specular reflection peak value is a gloss peak value measured at an angle very close to the specular reflection angle. The specular reflection peak value fluctuates depending on the unevenness of the surface of the measurement target, and when it is equal to the gloss value, it shows a smooth state without even fine unevenness on the surface. Further, the coarser the surface of the measurement target, the lower the value. That is, the lower the specular reflection peak value, the smaller the amount of reflected light 323.

The shielding coefficient is a coefficient indicating how much the solar radiation projected from the sun is blocked, with the amount of solar heat gained by the transparent float glass having a thickness of 3 mm as 1. The smaller the value of the shielding coefficient, the more it means that the solar rays from the sun are shielded.

In the first embodiment, the image clearly projected from the surface 23 side could be recognized in the design portion 22. Further, no image was projected on the surface on the extension line of the projection line 31, and the surface did not receive the transmitted light and emit light.

In the second embodiment, the image clearly projected from the surface 23 side could be recognized by the design unit 22. Further, as compared with Example 1, the surface on the extension line of the projection line 31 emitted a small amount of light, but the light emission was not so visually noticeable that the image was not projected.

In Example 3, the design unit 22 could recognize the image clearly projected from the surface 23 side. Further, as compared with Example 1, the surface on the extension line of the projection line 31 emitted a small amount of light, but the light emission was not so visually noticeable that the image was not projected.

In Example 4, the design unit 22 could recognize the image clearly projected from the surface 23 side. Further, as compared with Examples 1 to 3, the surface on the extension line of the projection line 31 emitted light, but the light emission was not so high that the image could be clearly confirmed.

In Comparative Example 1, the image clearly projected from the surface 23 side could be recognized in the design portion 22. In Comparative Example 1, the Log haze value is not within the preferable range. In Comparative Example 1, the image transmitted through the surface on the extension line of the projection line 31 was projected to the extent that it could be visually confirmed.

In Comparative Example 2, the design unit 22 could not recognize the image projected from the surface 23 side. That is, in Comparative Example 2, the image or image projected from the back surface 24 side on the design portion 22 could not be recognized from the front surface 23 side.

In Comparative Example 3, a transmissive screen film was used as the design unit 22. In Comparative Example 3, the visible light transmittance, the total luminous flux transmittance, and the gloss value are not within the preferable ranges. In Comparative Example 3, a clearly transmitted image was projected on the surface on the extension line of the projection line 31.

In Comparative Example 4, a transmissive screen film different from that of Comparative Example 3 was used as the design unit 22. In Comparative Example 4, the Log haze value is not within the preferable range. In Comparative Example 4, as in Comparative Example 3, a clearly transmitted image was projected on the surface on the extension line of the projection line 31.

With the above configuration, it is possible to provide a transparent sign effect system having an excellent appearance.
The transmissive sign effect plate 2 includes a design unit 22 on which light including an image or an image is partially projected from the projector 3, and the design unit 22 emits light including an image or an image projected from the projector 3. It is diffused and transmitted to the extent that it can be visually recognized from the other side (surface 23 side) of the projector 3, and the light including the image or the image is directly transmitted and the image or the image is projected on the floor surface, the ground, or the ceiling surface beyond it. It is a light diffusing part that never happens. With this configuration, when the transmissive sign effect board 2 is used as a window of a store or the like, the projected image or image can be clearly visually recognized, and the sign effect having an excellent appearance can be obtained. That is, when the projector 3 is installed in the store and an image or an image is projected onto the transmissive sign effect plate 2 which is a window, the image or image is projected by the design unit 22 provided on the transmissive sign effect plate 2. The light can be diffused and transmitted to the viewer outside the store. At this time, the light projected on the design unit 22 is diffused and transmitted, so that the light is not projected onto the floor surface or the ground beyond it. Therefore, no extra projection is performed on the floor surface, the ground, or the like, and an image or an image can be projected only on the design portion 22 to produce an advertisement or the like.

In addition, the viewer can check the inside of the store through the transparent portion 21. Therefore, it is possible to perform a more effective effect by combining the product placed in the store with the projected image or image. Further, the installation location of the projector 3 is not limited, and the projector 3 can be installed on the ceiling or the floor surface to project from diagonally above or diagonally below the transmissive sign effect plate 2. That is, when the window is viewed from outside the store, the transmissive sign effect plate 2 on which the image or image having a design is projected can be visually recognized without visually recognizing the projector 3. Further, since the projector 3 can be installed inside the store and the effect projected on the design portion 22 of the transmissive sign effect plate 2 can be visually recognized from outside the store, the projector 3 is installed outdoors with waterproof treatment. It can be installed without any special construction.

Further, the outer shell of the light diffusion transmission region 221 includes the outer shell of the projection region 222 on which an image or an image is projected (inside or overlapping state). With this configuration, all the light projected on the projection region 222 (design portion 22) is diffused and transmitted in the light diffusion transmission region 221 and the light directly transmitted from the projector 3 through the transmission portion 21 is the floor surface, the ground or the ceiling surface. It is possible to prevent it from being reflected in the image, maintain a good appearance, and produce a beautiful effect.

Further, the design portion 22 is a diffusion transmission sheet, and is detachably arranged on the back surface 24, which is the surface on which the projector 3 is arranged. With this configuration, the shape of the design portion 22 can be easily changed, and after the change, it is possible to easily switch to an effect using an image or an image having a matching shape. That is, by changing the shape of the design unit 22 (light diffusion transmission region 221) and the effect content and projection range of the projected image or image, various effects such as changing the effect according to the season or event can be obtained. It can be carried out.

Further, the transmissive portion 21 is composed of a smooth surface, and the design portion 22 is placed on the smooth surface of the transmissive portion 21 on the side on which the projector 3 is arranged, that is, on the back surface 24, which is the incident surface, by an adhesive substance such as a seal. It is pasted and formed. With this configuration, the design portion 22 can be easily attached and detached. Also, the image or image can be projected without distortion. Further, even when the transparent sign effect board 2 is installed in a high altitude place, management and maintenance can be easily performed.

Further, the shape of the design portion 22 has design characteristics such as characters and patterns. With this configuration, good appearance can be maintained even when no video or image is projected.

Further, the design unit 22 has a lower transmittance than the transmissive unit 21, and diffuses and transmits the image or image projected from the projector 3 on the back surface 24 of the transmissive sign effect plate 2 to the front surface 23 side. Make it visible from. With this configuration, a viewer such as a passerby can enjoy the production from the surface 23 side. Moreover, since the light transmitted through the design unit 22 is diffused, it is possible to prevent the image or image from being transmitted through the design unit 22 and being reflected on the floor surface, the ground surface, or the ceiling surface. Therefore, it is possible to prevent the effect of the design unit 22 from being reflected on the floor surface, the ground, or the ceiling surface in the same manner, and it is possible to enhance the effect and presence of the effect of the design unit 22.

The total luminous flux transmittance of the design unit 22 is 60 to 98%. With this configuration, the amount of light transmitted through the design unit 22 (projection region 222) (the amount of light distributed and transmitted within the design unit 22) can be set to an appropriate amount, and the image projected by the projector 3 can be clearly displayed from the opposite side. It is visible. Further, if the total luminous flux transmittance is 70 to 95%, the amount of transmitted light (the amount of light dispersed and transmitted in the design unit 22) can be made more optimum, and the image projected by the projector 3 is reversed. It can be seen more clearly from the side.

The visible light transmittance of the design unit 22 is 40 to 95%. With this configuration, the amount of visible light transmitted through the design portion 22 (projection region 222) can be set to an appropriate amount, and the image projected by the projector 3 can be clearly seen from the opposite side. That is, the amount of light is such that viewers such as passers-by can recognize that it is not dazzling and attracts attention, and it is possible to enjoy the production using images or images. Further, if the visible light transmittance is set to 50 to 90%, the amount of transmitted visible light (the amount of light dispersed and transmitted within the projection region 222) can be made more optimum.

The gloss value of the design unit 22 is 2 to 30. With this configuration, the amount of light reflected or dispersed by the design unit 22 (projection region 222) can be set to an appropriate amount. That is, the amount of light transmitted and the amount of light dispersed in the design unit 22 can be set to an appropriate amount, and it is possible to more clearly provide a viewer such as a passerby with an effect using an image or an image. Further, if the gloss value is set to 3 to 15, the amount of reflected or dispersed light can be set to a more optimum amount.

The Log haze value of the design unit 22 is 120 to 350. With this configuration, the projected light incident on the design portion 22 (projection region 222) can be appropriately dispersed. That is, the amount of transmitted light transmitted through the design portion 22 can be set to an appropriate amount, and the appearance of the transmission type sign effect plate 2 can be improved. In addition, the projected light can be appropriately dispersed in the design unit 22, and a more beautiful effect can be provided to a viewer such as a passerby. Further, if the Log haze value is 120 to 300, the amount of transmitted light transmitted through the design unit 22 can be made more appropriate, and if it is 120 to 200, the amount of transmitted light transmitted through the design unit 22 can be increased. It can be the optimum amount.

Further, the design unit 22 has a Log haze value of 120 to 350 and a visible light transmittance of 40 to 95%. With this configuration, the balance between the amount of visible light transmitted through the design unit 22 (projection region 222) and the light dispersed in the design unit 22 can be set to an appropriate amount. That is, the amount of light can be set so that viewers such as passers-by can recognize that it is not dazzling and attracts attention.

Further, the thickness of the design portion 22 can be 1 μm or more and 150 μm or less. The thickness of the design portion 22 refers to the thickness of the portion where the surface of the transparent material is appropriately surface-treated, such as blasting, to form the design portion 22, which is processed to diffuse and project light. If the design portion 22 is an appropriate sheet, it refers to the thickness of the sheet. When the design portion 22 is a sheet, the thickness can be 50 μm to 150 μm. With this configuration, the amount of light transmitted through the design portion 22 can be set to an appropriate amount. Further, it is possible to sufficiently secure a distance in the thickness direction for dispersing the projected light. For example, when a transparent design body having the same shape as the design portion 22 is adhered to the surface of the transparent glass and the design portion 22 is provided on the surface of the transparent design body, the transparent glass and the transparent design body are combined. It becomes the transmission portion 21.

Further, the projector 3 is arranged to project an image or an image toward the design unit 22 from the front upper direction or the front lower direction of the design unit 22. That is, in the projection line 31, the ground, the floor surface, and the ceiling (top surface) are arranged so as to be located on the extension line from the intersection with the design portion 22. With this configuration, it is possible to provide a viewer such as a passerby with an effect using an image or an image without visually recognizing the projector 3.

Further, the projector 3 is the same projection that projects an image or an image having a shape that matches the design shape of the design unit 22, a reduced projection that projects an image or an image that is one size smaller than the design shape of the design unit 22, and a design. At least one of the magnified projections that project an image or image that is one size larger than the design shape of part 22 is projected. With this configuration, it is possible to project an image or an image on the design unit 22 and select whether to project light on a surface that is an extension of the projection line 31.

It should be noted that the present invention is not limited to the configuration of the above-described embodiment, and many embodiments can be obtained.
For example, in this embodiment, the design portion 22 is provided on the back surface 24 side, but may be provided on the front surface 23 side or between these surfaces in the thickness direction. When the design portion 22 is arranged between the back surface 24 and the front surface 23 in the thickness direction, for example, the design portion 22 can be manufactured so as to be sandwiched between the two transmission portions 21. With such a configuration, the design portion 22 can be protected from dirt, scratches, and the like.

Further, for example, the design portion 22 may be in a form of being fitted into the hollowed out portion of the transparent portion 21 which is partially hollowed out. In such a form, the design portion 22 is less likely to fall off from the transmissive portion 21, and the life of the transmissive sign effect plate 2 can be extended.

The present invention can be used in the industry of transmissive sign staging boards used in show windows.
