Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an illumination light reflection display device that exhibits various expressive powers through rotation.

[Conventional technology]

Conventionally, although not shown in the drawings, a display device that exhibits a variety of expressive powers through rotation has been constructed by arranging triangular prisms of uniform length in a parallel manner in close contact with each other on each side of the triangular prisms. By rotating in the same direction at a limited angle around the vertical axis of Therefore, there are devices that display three different types of expressions.

[Problem that the invention attempts to solve]

The above rotating display device has the following problems.

(1) Since the display surface is made up of closely spaced triangular prisms, it is difficult to use fine display means, so only a rough representation can be made, and the display surface does not have a realistic sense of being divided.

(2) Since there is no change in the illumination light to the display surface, even if the display surface changes, the expression becomes ordinary and the display lacks appeal.

[Means for solving problems]

This idea involves coating both sides of a transparent substrate with a transparent resin coating having an optical refractive index different from that of the substrate, forming an uneven surface on one side of the substrate through preliminary treatment, and reflecting light at a desired position on the uneven surface. A single-plate light display board consisting of at least one panel provided with display means is arranged, and at least one or more light sources are arranged on the periphery of the light display board so as to be movable relative to each other by rotation or the like. The light source is configured to irradiate the light reflection display means of the substrate with restoring moving light by intermittent rotation, etc., so as to perform at least two types of corresponding display including light emission due to diffused reflection of the means.

[Effect]

When displaying at least two or more types of correspondence including light emission from a light reflective display means provided on one surface of the transparent substrate, the transparent substrate may be rotated with at least one light source disposed on the periphery side turned on. When the illumination light from this light source is intermittently irradiated into the substrate from one peripheral edge of the transparent substrate, a transparent resin coating having a light refractive index different from that of this substrate is applied to both surfaces of the transparent substrate. Therefore, the illumination light irradiated into the substrate can travel in the longitudinal direction of the substrate using an optical fiber method without leaking to the outside due to the difference in refractive index. When the illumination light traveling through the substrate reaches the light reflection display means provided on one side of the substrate, diffused reflection occurs and a light emitting display phenomenon occurs, which is emitted to the outside. Since this radiation action is performed by restoring movement such as rotation by at least one light source, it is possible to easily and reliably display two or more types of correspondence to the outside in succession.

〔Example〕

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

1 and 2 show an illumination light reflective display device according to a first embodiment of this invention. First, the configuration of the optical display board A, which is the basis of this invented device, will be explained. The optical display board A is constructed as follows. In the following explanation, in order to facilitate understanding, one side of the illustrated two-piece assembly will be explained. That is, this optical display panel A uses a transparent resin substrate 1 having good transmittance, such as an acrylic resin plate, as its base material. Both surfaces of the transparent resin substrate 1 are coated with transparent resin coatings 2 and 3 made of, for example, fluorocarbon resin or the like having an optical refractive index different from that of the substrate 1.

An uneven surface 4 is formed on one surface side of the above transparent resin substrate 1 (in the drawing, the coating 3 side where the two substrates 1 come into contact with each other) by applying a pretreatment agent. The uneven surface 4 has a size of 2 μ to 3 μ or less, so minute that it cannot be seen by the human eye, and is so small that it does not affect the background seen through the transparent resin substrate 1 from the thickness direction. At desired positions on this uneven surface 4, a light reflection display means 5 in the form of letters or pictures is provided using a special ink with good light reflectance by known screen printing or the like. (In the illustration, the substrates 1 are provided at back-to-back positions.) The transparent resin substrate 1 provided with the light reflective display means 5 by the above printing is placed in a baking furnace (not shown) and subjected to low-temperature baking. ing. In this embodiment, an adhesive-type transparent tape 7 with good transmittance is first adhered to the other peripheral edges except for one peripheral edge (the upper edge in the illustration) of the transparent resin substrate 1, and the outer peripheral edge of the transparent resin substrate 7 is An adhesive-type reflective tape 8 coated with metal plating with good light reflectivity is wrapped in layers, and a regular covering tape 9 is wrapped around the outer periphery of the reflective tape 8 to form a single package. It is formed on a single optical display board A according to.

A light source 10, such as a fluorescent light, is disposed on one peripheral edge side (the upper end side in the drawing) of the light display panel A according to this embodiment, for example, so as to be able to emit illumination light only in a downward direction. And this light source 10
With its one end connected to the rotating shaft 12 of the motor 11, the transparent resin substrate 1 is rotated in the circumferential direction around the shaft 12, perpendicular to the longitudinal direction of the transparent resin substrate 1, and periodically rotated directly downward. The display devices are arranged so that illumination light can be irradiated onto the substrate 1, and the display device as a whole is configured as a set of illumination light reflection display devices.
Note that by selecting a type of light source 10 capable of emitting colored illumination light, the display effect can be further improved.

As shown in FIG. 2, the illumination light reflective display device having the above-mentioned configuration is fixed in an upright manner, and the color light source 10 is connected to the motor 11 so that the light display panel A is attached to one periphery of the display panel A. When the motor 11 is driven with the colored light source 10 turned on, the colored illumination light from the light source 10 moves back to the substrate 1 by rotation or the like.
When the substrate reaches one peripheral edge, colored illumination light is irradiated into the substrate from this one peripheral edge side.

When colored illumination light is irradiated from the light source 10 as described above, both sides of the transparent resin substrate 1 are coated with transparent resin coatings 2 and 3 having a different optical refractive index from that of the substrate 1. Due to the difference in the optical refractive index in the substrate 1, the colored illumination light irradiated into the substrate 1 can travel parallel to the longitudinal direction of the substrate 1 using the same principle as an optical fiber without leaking to the outside. The colored illumination light traveling through the transparent resin substrate 1 is transmitted to the uneven surface 4 on one side of the substrate 1 (in the figure, the side where the substrates 1 are in contact with each other).
When reaching the light reflecting display means 5 provided in The irradiated colored illumination light causes diffuse reflection along the normal line (not shown) on the uneven surface at each position, resulting in a light emitting display phenomenon. That is, since most of the diffused reflection in the means 5 is performed substantially perpendicular to the longitudinal direction of the transparent resin substrate 1, this diffused reflection is radiated to the outside of the substrate 1 as a light emission display in the means 5. In this case, since the substrate 1 is a transparent body, the portion where the display means 5 is not provided will reflect on the uneven surface 4 at that position and exhibit a color display based on the ground color that is the same as the color of the light source 10. The part where the means 5 is provided irradiates to the outside a composite color that is a mixture of the color of the means 5 and the color of the light source 10, and thereby the background color of the substrate 1 and the composite color of the means 5 It can demonstrate expressive power that contrasts with colors.

Furthermore, since the light source 10 is rotated by the driving force of the motor 11, the contrasting light emitting display mode described above completely disappears when it passes one peripheral edge of the substrate 1, and the next light source 10 completes one rotation. The substrate 1 remains in a non-emissive state until the substrate 1 is returned to its original position on one peripheral edge of the substrate 1. In this way, the light display board A repeats a light emission display with a contrast between the ground color and the composite color when the light source 10 is irradiated, and a light extinction display when the light source 10 does not emit light until it has completed one cycle. As a result, it can be utilized as a new display medium that continuously displays two types of brightness and darkness to the outside.

In addition, in the optical display board A according to the above embodiment, when the light reflective display means 5 is a figure or a picture pattern, etc. that does not have front or back sides from either side, the same means 5 is applied to two transparent resin substrates 1. By providing this, the same figure or picture pattern can be visually recognized from the front and rear directions. However, if the figure or picture pattern has two sides, or has letters, etc., the first
As shown in the figure, by inserting an opaque intermediate material 6 between the bonding surfaces of the transparent resin substrates 1, it is possible to visually see each side as a display medium with completely different expressive power. can be doubled and diversified.

Furthermore, in the above embodiment, the light source 10 is connected to the motor 11.
Although the illumination light reflection display device according to this invention is not limited to the above-mentioned embodiment, for example, the light source 10 described above is By moving the light display board A back and forth in the front and back direction of the light source 10 or vice versa,
Similar to the above embodiment, it can be utilized as a new display medium that continuously displays two types of bright and dark correspondence to the outside.

FIG. 3 shows an illumination light reflective display device according to a second embodiment of this proposal. The structure of the optical display panel A in this second embodiment is exactly the same as that of the optical display panel A in the first embodiment described above. Therefore, a description of its configuration will be omitted. However, in the optical display panel A in this embodiment, a rotating shaft 14 may be provided at the center of the lower end side of the transparent resin substrate 1. Further, on one peripheral edge side (the upper end side in the drawing) of the substrate 1, two identical colored light sources 13A and 13B having the same configuration as described above are arranged horizontally in series. Both light sources 13A and 13B are integrally rotatably connected to a rotating shaft 12 that is vertically installed at the connecting portion of both, and can be restored by rotation in the circumferential direction about this rotating shaft 12. It is composed of Note that the above-mentioned light sources 13A and 13B are configured to emit different colors of light. Further, the optical display panel A in this embodiment is formed so that its width is wider than the length of one light source described above. Therefore, when both the light sources 13A and 13B mentioned above reach one peripheral edge side of the substrate 1, one side of the substrate 1 is illuminated with the entire amount of illumination light from one light source, and the color based on the light source on this one side is irradiated. The remaining part of the other side is configured to be illuminated with part of the illumination light from another light source and become a narrow-range reflective surface with a color based on the light source on the other side. .

In the illumination light reflective display device in the second embodiment, the light display plate A is fixed in an upright manner, and the bichromatic light source 13
The bichromatic light sources 13A, 13B are arranged on one peripheral edge side (the upper end side in the illustration) of the light display plate A in a rotatable state driven by a motor or the like (not shown).
3B is turned on, and when one of the color light sources 13A reaches directly above the light display board A, the one side of the substrate 1 corresponding to this side is
Since the entire amount of the colored illumination light is emitted from the light source 13A directly above this, the part on this side where the display means 5 is not provided exhibits a color display using the ground color that is the same as the color of the light source 13A, and the above-mentioned means The portion where 5 is provided can display a wide-area reflective surface that irradiates a composite color that is a mixture of the color of this means 5 and the color of the light source 13A. In addition, a part of the other side of the substrate 1, which is the other side, is irradiated with a part of the colored illumination light from the upper light source 13B on this side, so the part on this side where the display means 5 is not provided is The part where the means 5 is provided is partially displayed with a ground color that is the same as the color of the light source 13B, and the color of the light source 13B is the same as the color of the means 5.
It is possible to display a narrow-range reflective surface that irradiates a composite color that is a mixture of 3B colors.

What are the unique wide-area reflective surfaces and narrow-area reflective surfaces mentioned above?
Due to the restoring movement of both light sources 13A and 13B during rotation, the amount range of reflection changes moment by moment in proportion to the above-mentioned rotation angle, so it is possible to exhibit contrasting expressive power by increasing and decreasing different colors. Also in this embodiment, since both the light sources 13A and 13B are rotated, the contrasting light emission display mode described above completely disappears when both light sources 13A and 13B pass one peripheral edge of the substrate 1, and then both light sources 13A and 13B are rotated. , 13B makes a half turn and returns to rest on one peripheral edge side of the substrate 1. The substrate 1 remains in a non-emitting state. Therefore, the light display board A of this embodiment continuously displays different color combinations in which the reflection amount range changes moment by moment with the irradiation of different amounts by both the light sources 13A and 13B, thereby making it possible to change the color. You can create a variety of interesting color mixtures.

In addition, in this embodiment, two color light sources 13A, 1
3B are arranged in a single letter shape in series, but this invention is not limited to the above embodiment; for example, four colored light sources of the same shape as the above but different colors may be arranged in a cross shape in a plan view. By rotating this in the horizontal direction, it is possible to further increase the variety of color changes and the variety of color mixtures.

Further, in this embodiment, the light display plate A is simultaneously driven by a separate motor or the like (not shown) about the rotating shaft 14 at the center of the lower end, so that the light sources 13A,
By rotating it in the same direction as 13B or in a different direction, it is possible to fully demonstrate the expressive power of the light emission change of a more diversified mixture of different colors.

[Effect of idea]

This idea involves coating both sides of a transparent substrate with a transparent resin coating having an optical refractive index different from that of the substrate, forming an uneven surface on one side of the substrate through preliminary treatment, and reflecting light at a desired position on the uneven surface. A single-plate light display board consisting of at least one panel provided with display means is arranged, and at least one light source is arranged on one peripheral edge of the light display board so as to be movable relative to each other by rotation or the like. The light source is configured to irradiate the light reflection display means of the substrate with restoring moving light by intermittent rotation, etc., so as to perform at least two types of corresponding display including light emission due to diffused reflection of the means. When the above-mentioned light source placed on the peripheral edge of the transparent substrate is turned on and rotated relatively, at least two or more corresponding displays can be easily and reliably displayed, allowing for a variety of expressive power, and the display surface is transparent. The substrate is used, and the light reflective display means is provided by screen printing, etc., making it possible to display minute details.Furthermore, since the light source uses colors, a brilliant expression is reliably obtained and the display is appealing. It has the effect of being able to fully demonstrate.
