Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a signboard which is suitable for use in roads and public facilities, and has excellent attractiveness and visibility even in the case of backlight.

[0002]

2. Description of the Related Art Conventionally, various marking boards have been used in roads and public facilities. This signboard is a square, triangle, circle, etc. board with one or both sides with figures to be recognized, such as figures showing linear guidance, traveling direction, parking lot, etc. Since it is necessary to identify the figure, the shape and color tone of the figure are determined in consideration of the attractiveness and the visibility. by the way,
These signboards can be easily identified when viewed from the same side as the sunlight, but when viewed from the side opposite to the sunlight, for example, when the signboard is in the direction of the western day. In this case, there is a problem that it is difficult to identify the sign because the sign is shaded by the sun due to the backlight. Further, at night, it is remarkable especially when there is no lighting around, but there is a problem that it is difficult to instantly identify the figure because it is too dark. Therefore, various types of signboards such as reflective type, internal illuminated type, and external illuminated type have been proposed and put into practical use.

The reflection type is a sheet in which a sheet having a high light reflectance is attached to the marking surface, and particularly, the visibility of the figure is improved at night. Further, the internal lighting type is, for example, a marking surface on which the graphic is formed is a semitransparent plastic plate or the like, a light source serving as a backlight is arranged inside the marking plate, and the marking surface is illuminated by the light source. As a result, the visibility of the figure is improved. Further, the external illumination type is, for example, one in which a light source is arranged above the marking surface on which the graphic is formed and the visibility of the graphic is improved by illuminating the marking surface with the light source.

[0004]

However, in the above reflection type, it is effective when the light source is in front of the marking surface, but when the marking surface is in the direction of the western day. In the same manner as the conventional marking plate, the marking surface is shaded by the western sun, and the marking plate cannot be identified. Further, in the internally illuminated type, the visibility of the figure is improved as compared with the conventional non-illuminated type, but when the marking plate is particularly strong in the direction of the western day, Because the sun was too strong, I overcame the light source and the marking surface was shaded,
There is a problem that the figure cannot be easily identified. Further, the external illumination type has the same problems as the internal illumination type.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a signboard having excellent attractiveness and visibility even in the case of backlight.

[0006]

In order to solve the above problems, the present invention employs the following marking plates. That is, the marking plate according to claim 1 is characterized in that, in a marking plate having a figure to be recognized formed on at least one surface, a large number of holes are formed on the entire surface of the marking plate.

The sign board according to claim 2 is characterized in that, in the sign board having a figure to be recognized formed on at least one surface, a large number of holes are formed in the figure part.

The sign board according to claim 3 is the same as that according to claim 2.
In the described marking plate, the holes are evenly distributed in the figure.

Further, the sign board according to claim 4 is characterized in that, in the sign board in which a figure to be recognized is formed on at least one surface, a large number of holes are formed in a portion other than the figure on the surface. .

Further, the sign board according to claim 5 is the sign board according to claim 1, 2, 3 or 4, characterized in that a reflective sheet having a light-transmitting property is attached to the surface.
