本発明は道路標識に使用される再帰反射板を利用した偽

Although they are widely used for member's cards, transportation commuter passes and tickets, identification cards, etc., troubles related to cards (theft, forgery, modification, etc.) occur frequently, and measures to prevent these troubles are desired. Among these, counterfeiting is expected to be relatively easy if carried out by someone with specialized knowledge, by decoding the magnetic signal with the current configuration of magnetic cards and recording the same signal on another card.

もって本発明の詳細な説明する。The present invention has succeeded in making counterfeiting virtually impossible by using a metal or thin metal film pattern and a retroreflective plate on an ordinary m-card to check it with both magnetic recording and optical identification patterns. It is. The present invention will be described in detail below with reference to the drawings.

場合もある事は言うまでもない。Needless to say, the magnetic recording layer 2 may be provided partially as shown in FIG. 1, or may be provided entirely as in a commuter pass for public transportation.

されてもよい。Figure 2 shows a hard plastic sheet 1 (transparent or opaque) according to the present invention, which has the same structure as the one shown in Figure 1 up to the magnetic recording layer 2 and printing layer 3, but on the opposite side of the magnetic recording layer 2. The main constituent elements are a layer 5 containing a pattern 4 made of a thin film of metal or metal oxide (hereinafter referred to as a pattern layer), on which a layer 7 containing glass beads 6 is further layered. A focal layer 8 and a protective layer 9 may be further laminated thereon.

〜５００Åの厚さで蒸着する。Glass beads 6 having a size of about 20 μm to 88 μm are arranged on the surface of the focal layer by an electrostatic method or the like in a substantially straight line, that is, so that no uneven surface appears on the surface. In this case, a similar transparent resin layer 7 may be formed on the surface of the focal layer 8. Furthermore, if necessary, use transparent colorless or transparent colored ink on this surface,
A protective coating having a thickness of 0.05 nm to 0.1 nm may be formed. For example, a thin film containing indium oxide as a main component (for example, indium oxide/tin oxide = 0.9810.02 to 0.8510.
15 weight ratio) to a film thickness of 50A by vacuum evaporation, sputtering, or ion derating method.

The product of the present invention is produced by bonding the retroreflector plate on which the indium oxide pattern obtained as described above is vapor-deposited to the surface opposite to the magnetic recording layer of an ordinary magnetic card.

大きくなり過ぎて、特に光線を照射せずともパターンが
釘眼で容易に認識されるため好ましくない。To explain the anti-counterfeiting effect of the product of the present invention, the vapor-deposited thin film of indium oxide has good transparency, and in particular, a thin film with a thickness of 50λ to 50X cannot be seen visually unless you look carefully, but it is visible when compared with the non-vapor-deposited part. In the light region, the reflectance is improved by 3 to 20%. It is also easy to irradiate a light beam onto the Mal pattern on the card using an appropriate electro-optical device, extract the reflected light as an electrical signal, and determine the authenticity of the card. As explained above, the thickness of the deposited film is 50
If it is smaller than X, the reflectance is too small, making it difficult to recognize the pattern, while if the film thickness is greater than 500λ, the reflectance becomes too large, making it easy to recognize the pattern with a fixed eye even without irradiating it with a light beam. This is not desirable because it causes

中間層にパターンが設けであるので仮にパターンを認識
出来ても偽造は事実上不可能になるものである。In addition to magnetic signals, the magnetic card according to the present invention can extract optical signals by depositing a transparent reflective layer, and the pattern cannot be easily recognized with the naked eye. Furthermore, since a pattern is provided in the intermediate layer, even if the pattern can be recognized, counterfeiting is virtually impossible.
パターン４は文字、図形、バーコード等のいづれでもよ

The present invention also includes a case in which a pattern made of a thin film of metal or metal oxide is directly provided and the whole is covered with a transparent resin layer, that is, the pattern layer 5 and the glass beads layer 7 are not clearly distinguished.
