Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a pattern display plate in which characters, figures, patterns, etc. are displayed on a transparent plate. The displayed characters, figures, and patterns can be seen normally, and when appropriate light is incident in the up, down, left, and right directions from the end surface of the transparent plate, the characters, figures, patterns, and transparent plate can be seen through. I can't see,
The present invention relates to a pattern display plate in which characters, figures, and patterns cannot be seen at all when viewed from the back side, and the other side can be seen through.

[Conventional technology]

Conventionally, there are some which display characters, figures, and patterns from the inside of the transparent plate so that the transparent plate looks normal when viewed from the street.

[Problems to be solved by the device]

In the above-mentioned conventional example, when the transparent plate is viewed from the side, the characters, figures, and patterns displayed on it look normal, but from the room side, the characters, figures, and patterns appear to be reversed, and There was a problem that it felt uncomfortable.

This invention was devised for the purpose of solving such problems.

[Means for Solving the Problems]

As a means for solving the above-mentioned problems, the present invention displays characters, figures, patterns, etc. by a large number of dots of colors that are finely spaced on one surface of a transparent plate and Ground-colored dots are attached to the upper surface of the dots and parts other than these dots at the same fine intervals as described above, and light having arbitrary illuminance is turned on and off from the end surface of the transparent plate in the vertical and horizontal directions. A pattern display plate characterized by being configured as described above, or a pattern display plate characterized by being configured by bonding another transparent plate to one surface of the transparent plate to which the dots are attached. is there.

[Action]

According to the pattern display board of the present invention, the characters, figures, and patterns displayed on the pattern display board look normal when viewed from the front side, but the pattern display board is vertically, horizontally, and vertically from the end surface of the pattern display board. When a light having an arbitrary illuminance is incident on, the characters, figures, and patterns cannot be seen, and when the pattern display plate is viewed from the back side, the characters, figures, and patterns may appear to be reversed. Without seeing at all, you can see the other side through the gaps between many dots.

〔Example〕

FIG. 1 is a front view of the pattern display plate of the first embodiment of the present invention seen from the front surface, and FIG. 2 is a sectional view taken along line II-II of FIG.

In FIG. 1 and FIG. 2, reference numeral 1 is a pattern display plate formed of a transparent plate, and characters, figures, patterns (in this embodiment, a plurality of colored dots 2 are formed on the back surface 1a thereof at fine intervals. While displaying "L" character, etc.,
A ground color dot 3 is attached to the upper surface of the dot 2 of a certain color and a portion other than the dot with a fine interval as described above,
Further, the light source 4 is arranged so as to allow light to enter and block light from the upper, lower, left and right end surfaces of the transparent plate 1 ', thereby forming a pattern display plate.

FIG. 3 is a sectional view of a pattern display plate according to a second example of the present invention.

On the back surface 1a of the pattern display plate 1, there are dots 2 of a certain color for displaying characters, figures and patterns, and on the back surface 1a having the ground color dots 3 attached to the upper surface and the portions other than these dots, another transparent plate 1 '. Are joined together to form a pattern display plate.

When the pattern display plate 1 of the first and second embodiments of the present invention is viewed from the front surface 1b side, the characters, figures, and patterns displayed on the pattern display plate 1 (the example in the first embodiment " The L "character looks normal.

Then, when the light source 4 is turned on and light having an arbitrary illuminance is incident vertically and horizontally from the end face portion of the pattern display plate 1, the incident light is diffusely reflected in the pattern display plate 1, These characters, figures, and patterns disappear, and when the pattern display board 1 is viewed from the back surface 1a side,
Since the ground-colored dots 3 are attached to the upper surface of the dot 2 of a certain color on which the characters, figures, and patterns are displayed and the parts other than the dot with a minute interval, only the ground-colored dot 3 is attached. As a result, the characters, figures, and patterns do not appear to be reversed.

Then, it is possible to see the opposite side through the gaps between a large number of dots.

[Effect of device]

When the pattern display board according to the first embodiment of the present invention is viewed from the front side, the characters, figures, and patterns displayed on it can be seen normally, and the light source is turned on to turn on the pattern display board. When light having an arbitrary illuminance in the vertical and horizontal directions is incident from the end face portion, the incident light is diffusely reflected in the pattern display plate, and the characters, figures and patterns are completely invisible.

When viewed from the back side, the characters, figures, and patterns cannot be seen at all, and the other side can be seen through.

Further, as in the pattern display plate of the second embodiment, by connecting another transparent plate to the back surface of the pattern display plate to which dots for displaying characters, figures, patterns and dots of the background color are attached, The dots can be protected from peeling.
