DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be now described in more detail with reference to the illustrated embodiments.

However, the present invention is not limited to these embodiments.

Figs. I and 2 are sectional views showing an embodiment of a process of producing the present invention, and Fig. 3 is a perspective view showing the state in which a passport is open.

First, a face photograph display sheet 12 is formed in the same shape as each sheet 11 in a passport 10 shown in Fig. 3 by using a synthetic resin sheet approximately 0.1 to 0.2mm in thickness. Then, an engraved face photograph with density gradation is engraved at a proper portion of the face photograph display sheet 12 by means of a conventional known engraving apparatus, described below, based on a photograph 13 attached in the same manner as on a conventional passport. As a result, a passport in which the engraved face photograph display sheet is inserted and fastened can be produced.

In the above case, the face photograph is directly o engraved on a surface layer at a predetermined portion of the synthetic resin sheet. Next, the case, in which a colored engraving base layer is unitedly buried in a synthetic resin sheet and a face photograph is engraved on the colored engraving base layer, will be described.

In the same manner as above, a face photograph display sheet 12 is formed in the same shape as each sheet 11 in a I, n passport 10 by using a synthetic resin sheet 1 of approximately 0.1 to 0.2mm in thickness. Then, as shown in Fig. 1, a colored engraving base layer 2 is mounted on the face photograph display sheet 12 (the synthetic resin sheet In order to mount the colored engraving base layer, a method of applying paints, ink composite or the like or a printing method, such as offset printing, can be used.

Next, as shown in Fig. 2, the face photograph display sheet 12 provided with the colored engraving base layer 2 is applied with heat and pressure by means of a heating plate, a heating roller or the like so as to bury the colored engraving base layer 2 into the face photograph display sheet 12 (the synthetic resin sheet 1) and form a smooth plane unitedly composed of the colored engraving base layer 2 and the face photograph display sheet 12 (the synthetic resin sheet 1).

After that, a face photograph 16, which is a black and white shaded image with density gradation, is engraved at a proper portion 14 of such face photograph display sheet 12 by means of a conventional known engraving apparatus, described below, according to a photograph 13 attached in the same manner as in a conventional passport, so that a passport in which the face photograph display sheet is inserted an fastened can be produced.

Fig. 4 is a structural view of a conventional known -6-

engraving apparatus and shows the mechanism for engraving an engraved face photograph or a face photograph at a proper portion of a sheet according to a photograph document. The apparatus is disclosed in Japanese Patent Publication (Kokoku) No.54-31410, No.54-25451 and so on.

As shown in Fig. 4, numeral 21 denotes a scanning head provided with a light source lamp and a multiplication tube, and numeral 22 denotes an engraving head provided with an engrav:ing stylus which vibrates up and down. A document pedestal 23 for laying a photograph document 28 thereon and an ecigraving pedestal 24 for laying a sheet 29 thereon are respectively disposed under both heads 21 and 22 and connected to a swing arm 26 through a swing lever In the above arrangement, a spotlight from the light sour ce in the scanning head 21. shines a point on the photograph document 28, the light reflected from the point enters the light multiplication tube, and photoelectric current in accordance with the amount of the light reflected from the photograph document 28, that is, the shade of the photograph document 28 arises. The photoelectric current passes through a proper calculation amplification circuit and controls the degree to which the stylus of the engraving head 22 cuts into the sheet 29 (precisely, the colored engraving base layer disposed on a proper portion of the sheet 29).

Since the tip of the stylus is pyramidal, if the stylus cuts deep into the sheet 29, the area of a concave portion is large and the area of the remained portion of the sheet 29 is small. In other words, that corresponds to a highlight portion of the photograph document 28. On the other hand, if the stylus cuts shallowly, the area of the concave portion is small, the area of the remained portion is large, and that corresponds to a shadow portion of the photograph document 28. Thus, an engraved image with density gradation, such as a face photograph, is formed.

The number of lines in the direction of the reciprocation movement of the engraving pedestal 24 is determined by adding a periodical intermittent movement in accordance with the desired number of line,, md the speed of the reciprocation movement of the pedest.Ail to the up and down movement of the stylus in accordance with the shades.

When a line is cut in a reciprocation movement of the engraving pedestal 24, the engraving head 22 and the scanning head 21 connected to the engraving head 22 through a lateral transport lever 27 are laterally moved by a pitch in accordance with the number of lines. Then, another line is cut by a reciprocation movement of the engraving pedestal 24.

According to such operations, it is possible to cut the surface layer at a proper portion of an optional face photograph display sheet 12 (the synthetic resin sheet 1) or a portion of the colored engraving base layer 2 buried in the sheet 12 and to produce an engraved image or a black and white shaded image of an optional face photograph on the photograph document 28.

The kind of the synthetic resin -hecet 1 forming the face photograph display sheet 12 is particularly not limited, the sheet may be made of a conventional plastic material, such polyvinyl chloride resin, polyolefine resin 10 or the like.

Furthermore, as a coloring agent in the paints or the ink compositce used to mount the colored engraving base layer 2, a conventional inorganic pigment, a conventional organic dye or pigment or the like can be used.

As described above, according to the engraved face photograph display sheet, the face photograph display sheet and the certificate for use with the sheets, even if the attached photograph is exchanged for another photograph, since it is impossible to exchange the engraved face photograph, which is a black and white shaded image, of the present invention, identification can be easily and certainly performed. Therefore, it is possible to extremely effectively utilize an identification notebook, such as a passport, a certificate and so on.
