Abstract

PURPOSE:To obtain the number plate which is hardly forged or counterfeited by forming plural visible recessed parts which are different from an identification number on the surface of a number plate base under certain conditions. CONSTITUTION:On the number plate base 11 made of, for example, aluminum, the recessed parts (groove) 12 and projection parts 13 are formed over its entire surface almost vertically. Those recessed parts 12 and projection parts 13 are formed by, for example, rolling roller machining when the number plate base is rolled. Namely, the projection parts 13 are in level with the surface of the plate base 11 and the recessed parts 12 are pressed areas. Consequently, the number plate is hardly counterfeited as compared with grooving on a plane. In this case, the projection parts 13 are preferably small in area and positioned between the recessed parts 12. The recessed parts 12 and projection parts 13 at the center part 11a are deformed slightly and indefinitely. On the surface of the number plate base 11, a vehicle registration number 15 as the characteristic identification number is printed or painted after press machining.

[Purpose of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a number plate such as a vehicle license plate.

0002

2. Description of the Related Art Conventionally, a vehicle license plate is a plate made of, for example, aluminum with a vehicle registration number formed by press processing and then painted.

[0003] However, since the above-mentioned number plate can be formed relatively easily, it is easily forged/imitation. Therefore, there was a drawback that there was a high possibility that it would be used for crimes.

0004

As described above, in the past, license plates had the disadvantage that they could be easily forged/copied and were therefore more likely to be used for crimes. Therefore, it is an object of the present invention to provide a number tag that is extremely difficult to forge/counterfeit. [Structure of the invention]

[0005]

[Means for Solving the Problems] In order to achieve the above object, in the number tag of the present invention, in which a unique identification number is written, the identification number and the number tag are provided on the surface of the tag stand. The structure is such that a plurality of different visually visible uneven portions are formed according to certain conditions.

[0006]

According to the present invention, by using the above-described means, it is possible to make the number ticket stand difficult to maintain, thereby preventing it from being easily imitated.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a license plate for a vehicle according to the present invention.

In the figure, a number plate stand 11 made of aluminum, for example, has a plurality of recesses (grooves) 12 and convex portions 13 formed substantially along the vertical direction over the entire surface thereof. These concave portions 12 and convex portions 13
is formed during rolling, for example, by rolling roller processing.

That is, the convex portion 13 is the surface of the plate stand 11 itself, and is an area where the concave portion 12 is pressed. This makes counterfeiting more difficult than providing grooves on a flat surface. In this case, it is preferable that the area of the convex portions 13 is small and that the convex portions 13 are present between the concave portions 12 . In addition,
The back surface of the number plate stand 11 is flat.

[0010] Here, the recessed portion 12 and the convex portion 13 are as follows.
Although it may have a linear shape, in this embodiment it has a curved shape. In addition, the central portion 11a
The recesses 12 and protrusions 13 of the left and right parts 11b are irregularly deformed little by little compared to the recesses 12 and protrusions 13 of the left and right parts 11b. These shapes are preferably determined by calculation using a computer, etc., in order to eliminate the possibility of forgery/imitation by mechanical processing or the like.

[0011] In this way, the shapes of the recesses 12 and the protrusions 13 can be freely configured, and as shown in FIG. s t can be set arbitrarily.

It should be noted that the convex portion 13 is not limited to a straight line or a curved line, but may be an ellipse, a hyperbola, or a figure expressed by a higher-order mathematical formula. Further, the convex portions 13 can be formed by repeating a certain pattern or by following a certain rule.

In the above-described configuration, a vehicle registration number (vehicle number) 15 as a unique identification number is printed on the surface of the license plate stand 11, or is formed by a conventional method, that is, by painting after press working. be done. In this way, a license plate with a visually visible uneven pattern is created. As mentioned above, the number plate stand is difficult to maintain.

That is, a complicated uneven pattern is formed on the surface of the number plate stand. This allows the plate stand to be made special, thereby making it possible to prevent it from being easily imitated. Therefore, a license plate that is difficult to forge or imitate can be produced at a relatively low cost.

In the above embodiment, the uneven pattern was formed along the vertical direction of the plate stand in order to reduce the adhesion of dust, etc., but the pattern is not limited to this, and the uneven pattern is formed in the horizontal direction or in the vertical x horizontal direction. It is also possible to have it in two directions. Also,
It can be applied not only to vehicle license plates, but also to, for example, equipment manufacturing numbers.

Furthermore, if the plate base is die-cut from a flat plate, by periodically repeating the uneven pattern, it is easy to obtain a large number of plate stands with similar uneven patterns. possible. It goes without saying that various other modifications can be made without departing from the gist of the invention.

[0017]

[Effects of the Invention] As described in detail above, according to the present invention, a number tag that is extremely difficult to forge/imitation can be provided.
