Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a certificate issued by a local government office or its branch office, and more particularly to a certificate which is improved in display of a certified official seal to ensure reliability.

[0002]

2. Description of the Related Art A copy of a family register, an abstract, a resident's card, a seal stamp certificate, and various other types of certificates are issued at municipal offices, local offices, and the like of local governments.

In recent years, as part of the rationalization of clerical work in these local governments, data is being made online, and certificates such as certified family register and abstracts, resident's cards, and seal certificates are created by electronic devices. , Can be issued quickly.

As for the chief's seal or the like as a certified official seal to be stamped on such certificates, a colored mark with red ink such as red ink has generally been applied, but for certificates created by electronic equipment There are also cases where the seal image is stamped in black due to the electronic conversion of the certified official seal.

[0005]

By the way, according to the inventor's investigation, generally, there is a strong need for official seals as red stamps using colored ink for certificates, and some people have a resistance to black electronic official seals. Relatively many. In addition, when viewed from the viewpoint of falsification and forgery against the certified official seal, even the red ink has a problem in handling due to the recent sophistication of technology, and if it is a black stamp, the difficulty of authenticity determination further increases. , There may be a problem with the reliability of the certificates.

The importance of ensuring the credibility of the certificates tends to increase with the ease of quickly and easily creating and issuing the certificates due to the computerization of the authentication work described above. It is necessary to improve reliability and give the general public a sense of security.

As a measure against falsification and forgery of certificates, it has been practiced to use a special paper with a watermark on the paper itself or to use preprinted paper.
There are problems with paper management and cost.

The present invention has been made in view of the above circumstances, and further improves the measures for preventing falsification, forgery, etc. of the official seal portion corresponding to the production and issuance of certificates by electronic equipment, thereby further increasing the trust of citizens. It is an object of the present invention to provide a certificate that can obtain authenticity and can easily and reliably determine the authenticity of an authentication document.

[0009]

In order to achieve the above-mentioned object, the certificates according to the present invention have a luminescent certification official seal made of colored ink containing a fluorescent agent or the like on the front surface or the back surface of the certification paper. It is characterized by

[0010]

According to the present invention, since the official seal of the certification document is printed with a colored ink or the like, the reliability of the document is improved as compared with black printing, and the official seal is printed with a fluorescent ink containing a fluorescent agent or the like. Therefore, the authenticity of the authentication document can be judged by, for example, irradiation with ultraviolet rays.

Even if the authentication document is color-copied, the official seal portion of the copy document does not develop color even if it is exposed to ultraviolet rays, so that it can be easily and surely judged as a counterfeit.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a copy of a family register issued at a city office or its branch office as an example of certificates according to this embodiment.

As shown in the figure, certificates 1 of this embodiment
Then, "Certify that this copy is not different from the original copy of the original family register" on the upper surface of the certification sheet 2. , Etc. are displayed, and the date 4 proving the "issue date" and the chief's name 5 such as "the mayor's name" are displayed at the bottom, and the official official seal 6 is displayed to the right of the chief's name 5. There is.

Each of the above-mentioned displays is printed on the certification sheet 2 by an automatic authentication document preparation device which is an electronic device (not shown), and the text 3, the date 4, the chief's name 5, etc. are printed with black ink, for example. ing.

The certification official seal 6 is also printed as an electronic official seal by the same automatic certification document preparation device, but this certification official seal 6 uses fluorescent ink containing a fluorescent agent for the stamp portion of the automatic certification document preparation device. The stamp is colored red and is the same as a normal red stamp.

The seal image of the certified official seal 6 is perceived as a general red seal by the unaided eye, but it is supposed to emit fluorescence when irradiated with ultraviolet rays of a certain wavelength, for example. That is, an ultraviolet fluorescent coloring ink is applied as the coloring ink, and this ink is, for example, 15 to 35% of fluorescent pigment, 5 to 15% of water-soluble dye for coloring, and 35 to 65 of polyhydric alcohol.
%, 10 to 45% of water, and the like.

According to the certificates thus constructed,
By irradiating the seal image of the official stamp stamped with ink with ultraviolet rays for authenticity determination, it is possible to easily detect falsification or forgery by observing the reflection pattern of the ink portion due to the ultraviolet rays. As a device that emits ultraviolet light, if the emission wavelength covers the phosphor of the colored ink,
It can also be used in a normal black light emitting device and does not require a special device.

In this embodiment, the authenticity of the certification document is judged by printing the entire seal of the certified official seal with the fluorescent agent-containing colored ink or by using the fluorescent agent-containing colored ink only in a specific portion of the stamp imprint. You may do it.

[0020]

As described above, according to the present invention, by printing the official seal of the certification document with colored ink or the like, the reliability of the document is improved as compared with black printing, and the official seal of the official seal is used. By printing with colored ink etc. containing, it is possible to judge the authenticity of the authentication document by irradiating with ultraviolet rays,
Even if you make a color copy of the certification document, the official seal portion of the copy document will not develop color even if it is exposed to ultraviolet light.
It can be easily and surely judged as a fake. Therefore, it is possible to improve the prevention measures against falsification and forgery of the official seal corresponding to the production and issuance of certificates by electronic devices, and to obtain greater reliability of citizens. Excellent effects such as reliable performance can be achieved.
