Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a display device using optical fibers that allows displays of different systems to be illuminated repeatedly on a common display board.

Display devices that use optical fibers to illuminate light or images have recently become popular because they provide a wide variety of decorative effects and require only one or a limited number of light sources. Many of these display devices have a structure in which the proximal ends of a plurality of optical fibers are focused and positioned near the light source, and the distal ends on the opposite side are fixed from the back of the display panel. By the way, the display in such a display device is changed by rotating a disc-shaped filter provided in the light source, but in order to make the device even more varied, the disc-shaped filter is enlarged and the divisions are increased. Proposals have been made to use endless filters.
However, even in such a proposal, since there is a one-to-one correspondence between the light source and the display on the display board,
There is a limit to the number of changes that can be made, and improvements in this respect have been desired.

The present invention was developed in view of this situation, and its gist is a light source equipped with a focusing end made of multiple optical fibers and a filter that transmits light, does not transmit light, or is partially colored. using a plurality of illumination units arranged facing each other, disposing the tips of the optical fibers on a common display board so that the displays constituted by the other ends of the optical fibers in the illumination units partially intersect; The display device is characterized in that it is equipped with a chain mechanism for synchronously driving the filters in each illumination unit so that the filters transmit or non-transmit light or are colored differently.

The present invention will be described below with reference to drawings of embodiments.

The drawings are a perspective view of the display device of the present invention with the housing removed, FIGS. 2 and 3.
Each figure is a perspective view seen from the direction of the display board.
In this embodiment, two illumination units, which will be described later, are used, and for convenience of explanation, one is designated as U and the other as U'. The illumination units U, U' consist of a plurality of optical fibers 1 and a light source 2 equipped with a filter 22, and the proximal end 12 of the optical fiber 1 is focused to be located near the light source 2. ing.
The light source 2 in the illustrated example includes a lamp 21 and a transmission section 2.
2a and a non-transparent part 22b.
, and one light source 2 has a motor 2.
3 is installed. The other lighting unit
The configuration of U' is also the same as that of one unit U, except that the motor 23 is not included. Here, as the optical fibers 1 and 1' in the present invention, plastic optical fibers such as acrylic or styrene, or glass optical fibers are used, but there are certain points such as bending durability, workability, fiber thickness, and price. Therefore, the former plastic optical fiber is preferred.

Reference numeral 3 denotes a display board made of plastic, metal, wood, etc., on which displays 31, 31' corresponding to each illumination unit U, U' are provided, and the tips 11, 11' of the optical fibers mentioned above are provided. They are arranged so as to correspond to each display and so that some parts intersect with each other. That is, if this situation is explained with reference to FIGS. 2 and 3 showing the illuminated state, the display 31 ("A" in this example) corresponding to one illumination unit U will be as shown in FIG. The display 31' (in this example, "A, I, U") corresponding to the other illumination unit U' is placed on a common display board so that a part of each optical fiber 1, 1' intersects, as shown in FIG. It is located at 3. Note that 4 in the figure is a chain mechanism for synchronously rotating the filters 31, 31' in each illumination unit U, U'. This chain mechanism includes filter rotation shafts 24a and 24'.
a, gears 24b, 24'b, and a chain 24c, and this chain mechanism is attached to filter rotation shafts 24a, 24'a,
4'b are connected by a chain 24c, and when the motor 23 is driven, the filters 22, 22' are rotated in synchronization.

When using the display device of this embodiment, in advance, the transmitting parts 22a, 22'a and the non-transmitting parts 22b, 22'b of the filters 22, 22' in each illumination unit U, U' are aligned directly above the lamp 21. This light source 2,
2' is turned on and synchronously rotated by the chain mechanism 4. In this way, the symbol "A" of one illumination unit U is first illuminated as shown in FIG. 2, but at this time, the filter 22' of the other illumination unit U' becomes a non-transparent part 22'b. The display 31' is not illuminated. On the contrary, filter 22'
When the transparent part 22'a is positioned above the lamp 21' after rotating 180 degrees, the display 31' in this illumination unit U' is illuminated as "A, I, U" as shown in FIG.
"A" in one illumination unit U is not illuminated. As described above, in the present invention, it is possible to illuminate the same display board 3 with different systems of displays 31, 31' by the illumination units U, U'. In addition, in this example, a combination of light transmission and non-transmission is used, but this can also be a combination of a colored part - a non-colored part, or a combination of a colored part - a non-colored part - a non-transparent part, etc. by dividing the filter into three parts. It is also possible to perform a combination of these, and it is also possible to combine these with illumination of an image such as a pattern. Furthermore, the optical fibers in each illumination unit are not limited to being intertwined partially, but can also be intertwined over almost the entire surface of the display board.

Since the present invention has the configuration described in detail above, it is possible to repeatedly display two or more different systems on a common display board using multiple illumination units, so the decoration and display can be changed. In addition to being rich in content and increasing the appeal effect,
This can be achieved by synchronously driving the filters in each illumination unit, which has the advantage of simplifying the configuration.
