Description

[Detailed description of the invention] This invention is made of transparent plastic.

This is a book about traffic signs and other signs that use flexible round rod-shaped light guides.

# using optical fiber! Recently, various studies have been carried out as a substitute for the conventional signs that are coated on the entire display surface of nighttime paint, and this invention is one proposal in this regard. ◎ Figure 1 shows the basics of this invention. One book showing the composition, (1
) is a front plate made of opaque plate glass or plastic except for the dots (2) that form letters, etc., and (3) is a single dot that forms one dot, with one end connecting each dot. It is a round rod-shaped light guide located in the part (2), and is made of transparent plastic and has flexibility.

Note that a dot is the smallest unit of a transparent or translucent character, symbol, or figure (picture). One end of the light guide (3) is attached to the front plate (1) (dragon) <21
The other end is located at the light generating device t (41).

That is, the light generating device (4) is composed of a light source (for example, a halogen lamp) (5) and a reflector (uxyLiccToa)' (6) that reflects the light emitted from the light source (5). The other end of the light guide (3) is located at the focal point of the reflector (6).

Therefore, when the light source (5) is turned on by power from the power source (7), the light enters from the other end of the light guide (3).

Reach one end.

FIG. 2 is an example of displaying a required display based on the configuration shown in FIG. 1, and the second factor shows a traffic sign.

By the way, there are cases in which it is necessary to change the display content of a single sign every time a predetermined period of time elapses. In other words, depending on the temporal conditions of the road, the content of the regulations may have to be changed one after another.

This invention proposes a sign suitable for such a case, and Figure @3 is an example thereof. In Figure 3, (1
) is the front plate, (3-1) to (3-n) are the light guides, (
4) is a light generator, (5) is a light source, and (6) is a reflector.

(7) t:j power supply; (8-1) to (8-n) are optical switches;

A calculator (9) is installed in the middle of each light guide.
)K. QO is a timer,
The computer (9) selectively controls the optical switch based on a signal generated every time a predetermined time elapses from this timer. n]) is a memory in which various display patterns are stored, and is part of the calculator (9). Eggplant. This memory α
1) In K, information on which light switch to select according to multiple contents to be displayed, that is, one character to be displayed, etc., is stored for each display contents, and the contents are stored in a timer (10
The optical switch is read out in association with the signal generated from the optical switch and processed by a computer to selectively control the optical switch.

In other words, initially, for example, the odd-numbered optical switches are ON (the even-numbered switches are OFF at this time), but after a predetermined period of time, the even-numbered optical switches are set to ON (the odd-numbered switches are OFF at this time). be. Accordingly, light initially passes through the light guides corresponding to the odd-numbered light switches and is represented by the corresponding dots, and then light passes through the light guides corresponding to the even-numbered light switches.

The corresponding dora) [Therefore, it is displayed. The content will be displayed according to the selected combination of light switches in the following 1ml format.

Therefore, one sign IIK can display a plurality of mutually different display contents.

As described above, according to the present invention, one sign can display different display contents every time a predetermined period of time elapses, and the scope of use of the sign can be expanded.

By the way, as in this invention, the above-mentioned light guide.

Signs that combine a light source and one reflector have a smaller erasing force than the commonly used S sign that uses a light source and nine display masks (representing the shape of displayed characters, etc.), and has a Illusory images that tend to occur when the light source is not energized (in conventional signs, the light source is not lit under bright sunlight, but it appears as if it is lit due to sunlight reflection on the display mask surface) phenomenon), and it is extremely easy to see for drivers etc.! ! i
There will be 4 jobs.

[Brief explanation of the drawing]

FIG. 1 is a diagram for explaining the basic configuration of this invention,
The IEZ diagram is a diagram showing an example of display contents. FIG. 3 is a diagram showing an embodiment of the sign according to the present invention, in which (1) is a front plate, (2) is a door, (31 is a light guide),
(5) is a light source, (6) is a reflector, (7) is a power source, (8)
is a light switch, (9) is a calculator, QO is a timer, (6
) is memory. In the drawings, the same or corresponding parts are designated by the same reference numerals. Agent Shin Kuzuno − ψ Figure 1 Figure 2 Figure 2 Figure 3

Claims (1)

[Claims] A front plate made of plate-shaped glass or plastic and opaque except for a plurality of dots forming display characters, one end of each of which is located at each dot, and the other end of which is a light source. and a plurality of round bar-shaped light guides located at the focal point of the reflector of a light generating device comprising a reflector and a reflector. and a light switch provided in the said light guide. It consists of a computer that stores all of a plurality of display patterns and controls the optical switch, and it reflects the light generated from the light source on the reflector and enters it from the other end of the light guide, and directs the incident light to the light guide. The sign is characterized in that the display content of the dots is changed by guiding the dots toward one end and by causing the computer to move around a light switch every time a predetermined period of time elapses.
