CONSTITUTION:A face photograph display paper sheet 12 is formed in the same shape as each paper sheet of a passport 10 from a synthetic resin sheet 1 with thickness of about 0.1-0.2mm. Subsequently, a colored carving pedestal layer 2 is provided on the face photograph display paper sheet 12 (synthetic resin sheet 1) and both of them are bonded under heating and pressure using a heating plate or a heating roll to embed the face photograph display paper sheet 12 in the colored carving pedestal layer 2 to form a smooth surface wherein both of them are integrated. A face photograph 16 is carved in and expressed on the appropriate place 14 of the formed face photograph display paper sheet 12 as a black and white variable density image having density gradation from a photograph 13 bonded as is conventional by a carving apparatus to make it possible to prepare a passport having the face photograph display paper sheet kept therein.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to paper sheets displaying watermarked facial photographs, paper sheets displaying facial photographs, and certificate documents using them, which are used for checking facial photographs for identification. , More specifically, watermarked facial photo display sheets, facial photo display sheets, and certificates using them, which are used in ID notebooks such as passports, certificate documents, etc., which are used together with each sheet of paper in which required information is written. Regarding documents.

In the present invention, certificate documents include passports,
You can list stock certificates, bankbooks, personal checks, car registration certificates, etc.

[Prior Art and Problems to be Solved by the Invention] Conventionally, facial photographs attached to various types of certificates such as passports have been taken by the applicant or themselves and glued onto a designated sheet of paper of each type of certificate. It is used by attaching a stamp, stamping it with a seal to prevent counterfeiting, and pasting a transparent sticker on top of it.

However, since the photo attachment method described above peels off easily, there is a possibility that it may be replaced with another photo and be forged or altered.For example, if a passport, etc. is stolen or given away, it may be misused. Occasionally, unexpected damage may occur.

[Means for Solving the Problems] Therefore, the present inventor conducted various studies in order to solve the conventional problems as described above.

By engraving the face photo at the time of application for issuance on a synthetic resin sheet with a watermark or engraving it in two colors (for example, a combination of two colors such as white and black, white and brown, etc.), the sticky face photo can be removed from the photo. The present invention has been completed based on the discovery that even if it is replaced with a photograph, it can be easily identified and counterfeiting can be completely prevented.

That is, according to the present invention, there is a watermarked face photo display paper sheet used for checking with a face photo for identification, in which the watermarked face photo has a density gradation on the surface layer of a predetermined portion of a synthetic resin sheet. A watermarked face photo display paper leaf, characterized by a statue representation, is provided.

Further, according to the present invention, there is provided a face photo display paper leaf used for checking a face photo for identification, which has a smooth surface integrated with a synthetic resin sheet with a colored engraved pedestal layer embedded in the sheet. There is provided a facial photo display paper sheet, characterized in that the colored sculpture pedestal layer has a facial photo expressed as a statue with density gradation.

Further, according to the present invention, there are provided various certificate documents such as watermarked facial photo display paper sheets having the above-described configuration or passports formed by inserting facial photo display paper sheets.

[Function] In the watermarked face photo display paper sheet of the present invention, a watermarked face photo with density gradation is directly engraved (watermark engraving) on the surface layer of a predetermined portion of the synthetic resin sheet. In the face photo display sheet, a colored sculptural pedestal layer is embedded in a synthetic resin sheet to form a smooth surface integrated with the sheet, and the colored engraved pedestal layer has a sculptural representation (black and white) of the facial photo with density gradation. etc.) is engraved in two colors.

Therefore, even if the adhesive face photo is replaced with another photo, the face photo can be compared with the watermarked face photo display sheet of the present invention or the watermarked face photo displayed on the face photo display sheet of the present invention. By comparing and contrasting (checking in the same way as normal watermark printing) or comparing and contrasting with a face photo, it is easy to accurately determine whether the person is the real person, and counterfeiting can be completely prevented. can do.

In addition, in the present invention, a transparent face photograph is expressed as a statue directly on the surface layer of a predetermined portion of the synthetic resin sheet, and a two-color image (face photograph) such as black and white that is expressed as a statue on the colored sculpture pedestal layer is Because it is embedded in a synthetic resin sheet to form an integrated smooth surface, it has excellent durability and can withstand long-term use without causing friction damage compared to when photos are pasted together. It's coming.

[Examples] Hereinafter, the present invention will be explained in more detail based on illustrated embodiments, but the present invention is not limited to these embodiments.

1 and 2 are cross-sectional views showing an example of the manufacturing process of the present invention, and FIG. 3 is a perspective view showing the passport in an open state.

First, a synthetic resin sheet with a thickness of about 0.1 ms+ to 0.2 mm is used to make
A face photo display paper sheet 12 is formed in the same shape as each paper sheet 11. Next, a watermarked facial photograph 15 with density gradation is created from the photograph 13 attached in the conventional manner at an appropriate location 14 on the facial photograph display sheet 12 using a conventionally known engraving device to be described later.
By expressing it as a statue, it is possible to create a passport containing paper sheets showing a watermarked face photo.

The above is a case in which a transparent face photograph is directly expressed as a sculpture on the surface layer of a predetermined location of a synthetic resin sheet.Next, a colored sculpture pedestal layer is embedded and integrated into a synthetic resin sheet, and the colored sculpture pedestal layer is Explain the case of expressing a face photo as a statue.

Similarly to the above, face photo display sheets 12 are formed in the same shape as each sheet 11 of the passport 10 using a synthetic resin sheet 1 having a thickness of about 0.1 mm to 0.2 mm.

Next, as shown in FIG. 1, a colored engraving pedestal layer 2 is provided on the face photo display paper sheet 12 (synthetic resin sheet 1). As a method for providing the colored engraving pedestal layer 2, a method of applying a paint, an ink composition, etc., a printing method such as offset printing, etc. can be used. Next, as shown in FIG.
(Synthetic resin sheet 1) is thermocompressed using a heating plate or a heating roll, etc., so that facial photo display paper sheet 12 (
A colored sculpture pedestal layer 2 is embedded in a synthetic resin sheet 1),
Both form an integrated smooth surface.

Hereinafter, a face, which is a black-and-white gradation image with density gradation, will be created by a conventionally known engraving device, which will be described later, from the photograph 13 attached in a conventional manner at an appropriate location 14 on the face photograph display sheet 12 formed in this manner. By expressing the photograph 16 as a statue, it is possible to produce a passport containing paper sheets displaying a facial photograph.

Fig. 4 shows a conventionally known engraving device, and is a block diagram illustrating a mechanism for expressing a watermarked face photograph or a face photograph as a statue from a photographic manuscript at appropriate locations on a sheet of paper.
This is disclosed in Japanese Patent Publication No. 410, Japanese Patent Publication No. 54-25451, and the like.

In FIG. 4, 21 is a scanning head having a light source lamp and a light multiplier tube, and 22 is an engraving head having an engraving needle that vibrates vertically. Below both heads, there are an original table 23 on which a photo original 28 is placed and an engraving table 24 on which a sheet of paper 29 is placed, respectively, and the two tables are connected by a swing arm 26 through a swing lever 25.

In the above configuration, the spot from the light source in the scanning head 21 illuminates one point on the photographic original 28, and the reflected light from this point enters the photomultiplier tube, and the light intensity reflected from the photographic original 28 is reflected from the photomultiplier tube. In other words, a photocurrent corresponding to the density of the photographic original 28 is generated, and this photocurrent passes through an appropriate calculation amplification circuit to the needle of the engraving head 22 on the sheet of paper 29 (more precisely, it is placed at an appropriate location on the sheet of paper 29). Control the depth of the cut into the colored engraving pedestal layer).

Since the tip of the needle is in the shape of a pyramid, the deeper it cuts, the larger the area of the recessed hole becomes, and the smaller the area cut into the paper sheet 29. That is, if the hole is made shallower, the area of the recess will be smaller, and the remaining area will be larger, which will represent the shadow portion of the photographic original 28. As a result, an engraved image such as a watermarked face photograph having density gradation is formed.

The "number of lines" in the direction of the reciprocating movement of the engraving table 24 is determined by adding an intermittent movement with a constant period according to the desired number of lines and the speed of the reciprocating movement of the table to the vertical movement of the needle corresponding to the shade. do.

When one line is cut with one reciprocating motion of the engraving table 24, the engraving head 22 and the scanning head 21, which is connected to this by a transverse feed lever 27, move laterally by one pitch corresponding to the number of lines on the plate. , the engraving table 24 reciprocates again to cut a line.

By such an operation, the surface layer portion or the paper sheet 1 of an arbitrary face photo display sheet 12 (synthetic resin sheet 1) is removed.
By cutting a portion of the colored engraving pedestal layer 2 embedded in the photographic original 28, a watermark image of an arbitrary face photograph on the photographic original 28 or a black-and-white grayscale image can be created.

The synthetic resin sheet 1 forming the face photo display sheet 12 is not particularly limited in type.

A sheet made of a conventionally known plastic material such as polyvinyl chloride resin or polyolefin resin is used.

Furthermore, as the colorant of the paint or ink composition used when providing the colored engraving pedestal layer 2, various conventionally known inorganic pigments, organic dyes or pigments, etc. can be used.

[Effects of the Invention] As explained above, according to the watermarked facial photo display paper sheet, facial photo display paper sheet, and certificate documents using them of the present invention,
Even if you replace the attached photo, the watermarked facial photo that is expressed as a statue or the black and white shading image of the present invention cannot be replaced, so your identity can be easily and reliably verified. It can be used extremely effectively for notebooks, certificate documents, etc.
