[Industrial applications]

 The present invention relates to an electronic display mainly used for advertisement.

[0002]

[Prior art]

 Conventionally, various structures and functions of electronic indicators for advertising have been known, but the greatest feature of these electronic indicators is that they strongly appeal to people's eyes as optical information. In order to maximize these characteristics, it is not a so-called sign-type static display mode, but a so-called dynamic mode that actively attracts the attention of the viewer by changing the color or display position. Is desirable.

As a method for achieving such dynamic display, generally, a large number of light-emitting bodies such as a light bulb or a light-emitting diode are arranged on a display surface, and turning on / off of these light-emitting bodies is preset by a controller. By controlling based on the control form, for example, in the case of a character display, a plurality of characters are displayed so as to be sequentially moved from one side to the other side.

[0004]

[Problems to be solved by the device]

 However, in a dynamic display using such a light emitting diode, the light emitting diode is relatively expensive, and a large number of them are required, and further, a controller for control is required, so that the cost is high. In addition to the problem, there is a problem that the reliability of the controller remains uncertain due to vibrations, especially in the case of an on-vehicle electro-optical display.

Further, since a light emitting diode or the like exhibits a unique color and a dynamic display is performed by turning on / off the light, the color is changed unless plural kinds of light emitting diodes or the like having different colors are used. It was difficult to make the color change dynamically so that the color moved from one character toward the other character, and it was dissatisfied with respect to the attention of the observer.

Therefore, the present invention has been made as an attempt to provide an electro-optical display device that can achieve dynamic changes in color with a simpler and cheaper configuration and that is highly reliable in operation.

[0007]

[Means for Solving the Problems]

 The present invention employs the following configuration as a concrete means for solving such a problem.

In the electronic display according to the first invention of the present application, a light source for irradiating light and a translucent disc body are arranged rotatably and driveably at a position in front of the light source in the irradiation direction. A translucent member that is divided into a plurality of colors in the direction, a display plate whose surface is a display surface, and one end of which is arranged on the side opposite to the light source of the translucent member in a state of being directed to the light source and It is characterized by comprising a plurality of optical fiber cables whose ends penetrate the display plate from the back surface side thereof and are arranged in a protruding state on the display surface.

In the electronic display device according to the second invention of the present application, a light source for irradiating light and a translucent disc body are arranged rotatably and driveably at a position in front of the light source in the irradiation direction. A translucent member that is divided into a plurality of colors in the direction, a display plate whose surface is a display surface, and one end of which is arranged on the side opposite to the light source of the translucent member in a state of being directed to the light source and The display panel has a plurality of optical fiber cables whose ends penetrate the display panel from the rear surface side and are arranged in a protruding state on the display surface, and the display surface of the display panel has light reflectivity. The other end of each optical fiber cable is characterized in that the other end is processed so as to cause light diffusion.

[0010]

[Operation and effect of the device]

 According to the present invention, with such a configuration, the following actions and effects can be obtained.

According to the electronic display device of the first invention of the present application, a translucent translucent member partitioned into a plurality of colors in the rotation direction is arranged at a position in front of the light source in the irradiation direction, and When rotated, the light emitted from the light source passes through the light-transmitting member, enters one end of each optical fiber cable, passes through the optical fiber cable, and is emitted from the other end on the display surface side of the display plate. It is captured by the viewer's eyes and recognized as predetermined light information.

In this case, the color of the light incident on the optical fiber cable due to the rotation of the translucent member sequentially changes corresponding to the color section of the translucent member. Therefore, for example, by appropriately selecting the mounting position of one end of each optical fiber cable to the translucent member and the mounting position of the other end on the display surface, for example, the optical information displayed on the display surface, For example, since the color of text information can be moved continuously to the left or right or up and down, it has a greater impact on the viewer's visual sense than when the text information of a single color changes, and a stronger attention-giving action. Will be done.

Therefore, according to this electronic display, by rotating the translucent member, the light information transmitted through the translucent member and displayed on the display surface through the optical fiber cable changes with the color. Since the viewer's attention is more actively called for, it has an extremely simple and inexpensive configuration, but has a higher advertising function than, for example, the conventional dynamic display method with no color change. It has an extremely useful effect of being able to exhibit.

According to the electronic display device of the second invention of the present application, in addition to the above-described action and effect, the following unique action and effect can be obtained. That is, since the display surface of the display plate has light reflectivity and the other end of each optical fiber cable is end-treated so as to cause light diffusion, radiation from the other end of the optical fiber cable is performed. The light thus diffused appropriately not only in the directivity direction of the other end (that is, in the front direction from the display surface) but also in the surroundings and is reflected on the display surface. As a result, the observer simultaneously recognizes the real image radiated from the other end of the optical fiber cable and the virtual image reflected on the display surface as one optical information, compared with the case where no virtual image occurs, for example. In addition, it is possible to obtain optical information with higher luminous intensity and a large visual area, the alerting action is further enhanced, and a higher advertising function can be exhibited.

It is arranged (see FIG. 2).

As shown in FIGS. 1 to 3, the display plate 3 has a reflective film material 8 attached to the back surface side of a transparent acrylic plate, and the surface 3 a thereof is used as the light reflective display surface 4. On the display surface 4, a predetermined character type, for example, three character types 5, 6, and 7 of "day", "book", and "circle" in this embodiment are attached and fixed. Then, in order to make these three characters stand out more clearly by lightning and to be recognized more clearly, a plurality of optical fiber cables 15, 15 ,. The ends 15b 1, 15b, ... Are arranged at a predetermined interval.

As shown in FIG. 2, the plurality of optical fiber cables 15, 15, ... Are provided with the character patterns 5 to 7 and the bracket 13 arranged on the rear side of the display plate 3, respectively. It has such a length that it can straddle it. Then, one end 15a of the optical fiber cable 15 on the side of the bracket 13 forms an end face orthogonal to the axial direction thereof, while the other end 15b on the side of the display plate 3 is subjected to an end treatment as shown in FIG. It has a rounded end shape so that the light emitted from it can be diffused to the surroundings. The end portion of the other end 15b of the optical fiber cable 15 is treated by bringing a heating molding member such as a hot plate into contact with the end portion cut at a right angle to the axial direction to remove the covering material of the optical fiber cable 15. This is a process of exposing the core by heat shrinking in the axial direction.

The plurality of optical fiber cables 15, 15, ... Having such a configuration are bundled into corresponding character types 5, 6, and 7, respectively, and are respectively divided into a first bundle 21, a second bundle 22 and a third bundle 22. In addition to the bundle 23, the respective bundles 21 to 23 are bundled at the intermediate position 20b near the one end 15a of the optical fiber cable to form the optical fiber cable bundle 20. Then, one end 20a of the optical fiber cable bundle 20 (that is, an end portion 15a, 15a, ... Of the plurality of optical fiber cables 15, 15, ...) Is formed in an arc shape and is attached to the bracket 13. On the other hand, it is fixed with its end facing forward. When fixing the one end 20a of the optical fiber cable bundle 20, when the three letters “day”, “book”, and “circle” are made to stand out by the radiated light from the plurality of optical fiber cables 15, 15 ,. Depending on the order in which the colors are changed (“day” → “book” → “maru” or “maru” → “book” → “day”), the optical fiber cable 15, The positions of the ends 15a, 15a, ... Of 15 ... Are different in the arc direction, which will be described later.

Immediately in front of the bracket 13 (that is, in front of the directing direction of the one end 20a of the optical fiber cable bundle 20), the optical fiber cable is attached to the motor shaft 14a of the motor 14 fixed to the bracket 13. A disk-shaped light transmitting member 12 that rotates in a close state is arranged at one end 20a of the bundle 20. The translucent member 12 is composed of, for example, a colorless and transparent acrylic plate, and its entire area is divided into four sections in the rotation direction, and each divided section is given a different color, and these are respectively given a first color. The area 12a, the second color area 12b, the third color area 12c, and the fourth color area 12d. It should be noted that this color section can be easily realized by various means, for example, by separately applying paints having different translucent colors or by sticking cellophane paper of different colors.

Further, in front of the translucent member 12, a light source 11 provided with a halogen bulb or the like is arranged so as to irradiate the translucent member 12 at a portion radially deviated from its rotation center. ing.

In the electronic display 1 configured as above, when the light is radiated from the light source 11 toward the translucent member 12 while the translucent member 12 is rotated, the emitted light is the translucent member. At one end 20a of the optical fiber cable bundle 20 as colored light having a predetermined color by sequentially passing through each of the 12 color regions 12a to 12d, one end 15a, 15a ,. , And is radiated from the other ends 15b, 15b, ... through the respective optical fiber cables 15, 15, ..., and brightens the respective characters of the corresponding character patterns 5-7.

In this case, since the color of the light incident on one end 15a, 15a, ... Of each optical fiber cable 15, 15 ,. Also, in the characters "day", "book", and "circle" of the character types 5 to 7, the color of light that makes them stand out sequentially changes. Therefore, for example, one end 15a, 15a, ... Of each of the optical fiber cables 15, 15, ... Corresponding to the character 5 “day”, the character 6 “book”, and the character 7 “circle”, respectively. By arranging in order from the foremost end to the rearmost end of the translucent member 12 in the rotation direction, the display color on the display board 3 is continuous in the order of "day" → "book" → "circle". Change to run into. On the contrary, one end 15a, 15a, ... of each optical fiber cable 15, 15, ... Corresponding to the letter 5 “day”, the letter 6 “book” and the letter 7 “circle”, respectively. Are sequentially arranged from the rearmost end to the frontmost end in the rotation direction of the translucent member 12, so that the display color on the display board 3 is in the order of “circle” → “book” → “day”. It changes so that it flows continuously.

That is, in the electronic display 1 of this embodiment, the positional relationship between the one end 15a, 15a, ... And the other end 15b, 15b, ... Of each optical fiber cable 15, 15 ,. By doing so, it is possible to make the color change mode on the display surface 4 different. Although the character display is described here, the invention of the present application is not limited to this, and it is needless to say that the present invention can be applied to various display forms such as a picture display.

By the way, in the electronic display 1 of this embodiment, as described above, the optical fiber cables 15, 15, ... Which are arranged at the outer edge portions of the character patterns 5 to 7 of the display surface 4 of the display plate 3 are provided. The one end 15a, 15a, ... makes the letters appear brighter to promote the attention of the observer. The attention-giving action is further enhanced by the letters being more clearly highlighted. Specifically, the brighter the emitted light from the other end 15b of each optical fiber cable 15 and the larger the emitted light, the more clearly a character can be recognized by a viewer.

For this reason, in the electro-optical display device 1 of this embodiment, as described above, the optical fiber cables 15 attached to the display surface 4 in a protruding state while the display surface 4 is provided with light reflectivity. The other end 15b, 15b, ... Of 15, ... Is given a light diffusing action by end treatment. By doing so, as shown in FIG. 3, the light diffused from the other end 15b of the optical fiber cable 15 is reflected by the display surface 4, and the observer sees the actual light (real image) from the other end 15b and this. Both of the virtual images reflected at 4 (see reference numeral 15b ') are visually recognized. As a result, each of the above characters will be highlighted by a light amount twice as large as that in the case where a virtual image does not occur, for example. It can recognize the characters.

Although the electronic display 1 mounted on the truck 50 has been described as an example here, the present invention is not limited to this, and is widely applied as a general electronic display for advertisement. Of course you can. However, when it is applied to the vehicle-mounted electro-optical display 1 as in this embodiment, the electro-optical display 1 itself has a mechanical structure as described above even if vibration occurs due to traveling of the vehicle. For example, as compared with a conventional electro-optical display that is electrically controlled by a controller, it has the advantages of less failure and high reliability in operation.
