JPS602960Y2 - PIN identification set using lines - Google Patents

Description

[Detailed explanation of the idea] The present invention relates to a password revealing set using lines.

In particular, it can be used for securities that need to be prevented from forgery or counterfeiting.

In other words, the present invention consists of a PIN consisting of lines at regular intervals on a support such as paper, and a PIN with parallel and misaligned lines at the same spacing around the periphery excluding the PIN. The background of the lines is arranged in such a way that it cannot be confirmed without the use of auxiliary means, and the background is arranged in such a way that it cannot be confirmed without the use of auxiliary means. This is a password display set using multicolored greenery, characterized in that it is made of a combination with an auxiliary sheet that is provided, and that at least one of the respective supports is transparent to the extent that it can be seen through.

The password revealing set according to the present invention is used by overlapping a password formation and an auxiliary sheet, and by overlapping the password, the hidden password is revealed.

The present invention will be explained below with reference to the drawings.

The drawing is an enlarged view showing an embodiment of the present invention.

FIG. 1 shows a password formation 1 constituting one part of the present invention,
From background 2 and password 3, this back
Grand 2 and PIN 3 are more careful about the gap between each other.

On the other hand, the auxiliary sheet 4 constituting the other part of the present invention shown in FIG. 2 has uniform lines on the support.

These lines have the same spacing as the lines of the background 2 of the password formation 1.

The multi-green patterns applied to the password formation 1 and the auxiliary sheet 4 of the present invention actually have smaller intervals than shown in the drawings.

Therefore, the password 3 cannot be identified with the naked eye.

However, when these two are overlapped, password 3 is clearly revealed.
This is shown in FIG.

In other words, the lines of back ground 2 and the lines of auxiliary sheet 4 overlap, but the lines of password 3 do not overlap with the lines of auxiliary sheet 4, and the lines of password 3 and background 2 overlap. There is a difference in density, and this makes the password visible.

In addition to the above-mentioned linear Manryoku lines, it is also possible to use curved lines such as concentric Manryoku lines and spiral lines.

Furthermore, by partially changing the thickness of the green background 2 or the line 3 of the password, or by partially changing the amount of ink, it can be seen with the naked eye. It is possible to obtain code formations with other visible patterns.

An example of this is shown in FIG. 4, and since there is a pattern 5 that is visible to the naked eye, this serves as camouflage and makes the password 3 even more obvious.

When the password formation has different thicknesses in different parts,
It is preferable to use an auxiliary sheet 4 made of a multi-colored flower whose thickness is the same as or even thicker than the thickest part of the multi-colored green.

When this auxiliary sheet 4 is superimposed on the password formation 1, as shown in FIG. 5, the pattern 5 visible to the naked eye becomes partially or completely invisible, and the password 3 becomes visible.

Furthermore, in the password forming product of the present invention, not only one password but also a plurality of passwords can be formed using parallel lines that are independent from each other and are slightly spaced apart from each other.

In this case, it is preferable that the auxiliary sheet has a thickness of enough to hide the background of the other passwords while leaving only one password.

It can also be overprinted with other colors.

In particular, when printed with two similar colors, it cannot be forged by color separation using a camera.

As explained above, the password display set according to the present invention allows the password to be easily confirmed by overlapping the password forming material and the auxiliary sheet, but it cannot be seen with the naked eye and is difficult to forge. be.

Further, the password forming object can be produced only by cutting and pasting the film.

The PIN according to the present invention can be used for stock certificates, bonds, checks, promissory notes, certificates, gift certificates, etc., and since it cannot be identified from its appearance, it can also be used as a lottery ticket.

[Brief explanation of drawings]

The drawings are enlarged views showing an embodiment of the present invention, in which Fig. 1 shows the PIN code formation, Fig. 2 shows the auxiliary sheet, Fig. 3 shows the auxiliary sheet overlapped with the PIN code formation, and Fig. 4 shows the PIN code formation as seen with the naked eye. FIG. 5 shows a password formation having a pattern visible in FIG. 4 when an auxiliary sheet is superimposed on the password formation of FIG. 1...Password formation, 2...Background, 3...Password, 4...Auxiliary sheet, 5...Pattern.

Claims (1)

[Scope of utility model registration request] On a support such as paper, there is a PIN code consisting of ten green strips at regular intervals, and the surrounding area other than this PIN code is made up of parallel but misaligned lines with the same spacing as the lines forming the PIN code. A PIN code forming material in which the background background is arranged in such a manner that it cannot be confirmed without the use of auxiliary means, and an auxiliary sheet in which parallel lines having the same spacing as the above-mentioned parallel lines are uniformly provided on a support. A password display set using parallel lines, characterized in that at least one of the respective supports is transparent to the extent that it can be seen through.
