The IC module 7 having such a structure is held by the IC module holding layer 18, as shown in FIG. 3(a). In this case, the IC module holding layer 18 corresponds to the substrate 71 of the IC module 7, a substrate corresponding layer 18a that accommodates this substrate 71, and an IC chip body 72 including the IC chip 72a, and corresponds to the IC chip body 72. It has an IC chip compatible layer 18b that accommodates the IC chip.

Further, an antenna 60 electrically connected to the IC chip 72a of the IC module 7 is interposed between the substrate corresponding layer 18a and the IC chip corresponding layer 18b of the IC module holding layer 18. The IC module 7 and the antenna 60 electrically connected thereto via the IC chip 72a constitute a combined body 8 as shown in FIG. 3(c). This antenna 60 is made of copper, for example, and is interposed between the substrate corresponding layer 18a and the IC chip corresponding layer 18b. Note that the antenna 60 is not limited to copper, and may be made of various materials such as copper alloy, iron, and stainless steel. Furthermore, the antenna 60 in FIG. 3(c) schematically represents a loop antenna, and the combination 8 is an NFC-compatible tag that operates at 13.56 MHz, for example. The present invention is not limited to this, and may operate in the 900 MHz UHF band, for example.

Here, the function of the combined body 8 will be explained based on the configuration diagram of the combined body shown in FIG. 5(a). The combined body 8 includes an IC chip 72a built in an IC chip body 72, and an antenna 60 electrically connected to the IC chip 72a. The IC chip 72a includes a control section 74 that performs various calculations, judgments, and commands, and a power generation and holding section 77 that generates and maintains necessary operating power from radio waves received by the antenna 60. Note that a power storage device such as a secondary battery may be provided in addition to the power generation/holding section 77 so that it can operate even when no radio waves are being received.

The IC chip 72a also has an interface section 76 that obtains power from radio waves received by the antenna 60, converts received information into a decodable code, and converts information to be transmitted into radio waves. . The IC chip 72a also includes a RAM (volatile memory) that is a temporary storage device for calculations of the control unit 74, a ROM (nonvolatile memory) that is a storage location for fixed information, and an E2PROM that can be rewritten as necessary. The storage unit 75 is comprised of NVM (rewritable non-volatile memory) such as a flash memory.

The storage unit 75 stores, for example, unique information such as the name and date of birth of the owner of the passport, character information such as a unique number associated with the owner, and facial photo information, as displayed on the information page 2; Either or both of the following and related information associated with these unique information can be recorded.

Additionally, the combination body 8 basically receives a signal of a predetermined frequency from an external device, executes the instructions included therein, and transmits the result to the external device as a signal of a predetermined frequency. Can perform a series of actions. In this embodiment, non-contact communication is performed with an information display device 200, which will be described later, as an external device.

Note that the IC module holding layer 18 has an IC module storage space 30 in which the IC module 7 is stored, by an opening 31 formed in the substrate corresponding layer 18a and an opening 32 formed in the IC chip corresponding layer 18b. Further, this IC module storage space 30 is sealed from above and below by the above-mentioned intermediate layer 17 and an additional intermediate layer 19 provided on the lower surface of the IC module holding layer 18. The substrate corresponding layer 18a and the IC chip corresponding layer 18b of the IC module holding layer 18, the white layer 15, and the additional intermediate layer 19 are all made of white polycarbonate.

(iii) Laser light printing layer, first outer surface transparent layer, etc. By the way, the laser light printing layer 14 is colored and blackened by the irradiated laser light, and can display desired characters. For this reason, the laser beam printing layer 14 includes polycarbonate containing a laser beam coloring accelerator, and by irradiating the laser beam printing layer 14 with laser light, the laser beam coloring accelerator has thermal energy. In this case, the carbon contained in the polycarbonate that is in contact with the laser light coloring accelerator burns and turns black, thereby displaying characters.

Further, a first outer surface transparent layer 13 is provided on the upper surface of the laser beam printing layer 14, and a hologram 5 as shown in FIG. 1 is arranged between the laser beam printing layer 14 and the first outer surface transparent layer 13. It's okay. Note that the hologram 5 may be either a relief hologram or a volume hologram. The laser print layer 14 is made of polycarbonate containing a laser color accelerator, and the intermediate layer 17, the first outer transparent layer 13, and the second outer transparent layer 20, which will be described later, are all made of transparent polycarbonate. .

(iv) Transparent window, etc. Further, on the lower surface, that is, the inner surface, of the first outer transparent layer 13, printing 51 such as letters, patterns, etc. is applied. Furthermore, a second outer surface transparent layer 20 is provided on the lower surface of the additional intermediate layer 19, and a print 52 of characters, patterns, etc. is also applied to the upper surface, that is, the inner surface, of this second outer surface transparent layer 20. Furthermore, an aerial image is formed through the white layer 15, the core layer 16, the intermediate layer 17, the IC module holding layer 18, and the additional intermediate layer 19 into a transparent window 40 made of a transparent material and on the side closest to the laser beam printing layer 14. A film 10 is provided. When the information page 2 is viewed in plan from the normal direction of the main surface of the information page 2, the aerial imaging film 10 is formed at least in a region that overlaps with the transparent window 40. In addition, the aerial imaging film 10 is placed on the side closer to one surface of the information page 2 on which unique information such as the face photo 3 is displayed than the transparent window 40 in the thickness direction of the information page 2, that is, the side that It is formed on the side closer to the printing layer 14 and the first outer transparent layer 13.

(v) Aerial Imaging Film Next, the structure of the aerial imaging film 10 will be explained. 4(a) is a schematic perspective view of the configuration of the aerial imaging film 10, FIG. 4(b) is a partially enlarged view thereof, and FIG. 4(c) is a schematic perspective view of the configuration of the aerial imaging film 10. It is a schematic diagram for explaining.

As shown in FIG. 4(a), the aerial imaging film 10 has a plurality of substantially cubic or rectangular parallelepiped-shaped penetrations regularly arranged in the vertical and horizontal directions on one surface of a flat film base material 12, as shown in FIG. 4(a). It has a structure in which a large number of holes are formed, and a large number of two-sided reflective elements 11 forming two adjacent sides of the through hole. Among these, in FIG. 4(b), which is an enlarged view focusing on the dihedral reflective element 11 at the upper left of the paper, among the four sides of the dihedral reflective element 11 having a substantially cubic or rectangular parallelepiped through hole, The first reflective surface 11a and the second reflective surface 11b, which are two adjacent side surfaces, may be subjected to some specular reflection treatment, for example, metal plating treatment. However, even without such specular reflection treatment, it is possible to obtain the reflection characteristics of the two-sided reflection element 11 due to the characteristics of the film base material 12 itself. However, it is preferable that the surface roughness of the first reflective surface 11a and the second reflective surface 11b be mirror-like with a surface roughness of 20 nm or less.

As shown in FIG. 4B, the aerial imaging film 10 has a first reflective surface 11a and a second reflective surface 11b that are adjacent to each other and have widths Wa and Wb, and a depth d thereof, and The surface 11a and the second reflective surface 11b intersect at mutually different angles θab. Here, the film base material 12 can have a thickness of approximately 50 μm or more and 500 μm or less, for example. In this case, d is the same as the thickness of this film base material. Note that the configuration of the two-sided reflective element 11 is not limited to a through hole, but may be a recessed portion having a constant depth shallower than the film base material 12. Further, Wa and Wb can be, for example, 50 μm or more and 200 μm or less, but are not limited to this range. Further, θab is preferably around 90°, for example, but does not necessarily have to be a substantially right angle, and can be any intersection angle.

As a member of such an aerial imaging film 10, an aluminum plate, a nickel plate, or the like can be formed by electroforming, for example. Furthermore, it is also possible to form a large number of grid-shaped two-sided reflective elements 11 using a resin such as acrylic as a base using a nanoimprint method or the like. In the latter case, in order to improve the specularity of the first reflective surface 11a and the second reflective surface 11b, a metal coating can be applied, for example, by sputtering or the like.

Next, the principle by which the aerial imaging film 10 reflects light emitted from an object placed at a predetermined position and forms an image of the object in the air will be explained. The principle is that a plurality of so-called "two-sided corner reflectors" are arranged as unit optical elements, and when the light beam emitted from the object to be projected passes through each of the unit optical elements, two mirror surfaces of each of the unit optical elements It takes advantage of the fact that it reflects twice, once each time. As a result, it is possible to form an image of the object to be projected at a plane-symmetric position of the object with respect to the plane (element surface) on which each unit optical element is arranged, as described in, for example, Japanese Patent No. 4900618. Are listed.

Based on the above, the principle will be briefly explained. FIG. 4C is a schematic plan view of the aerial imaging film 10 viewed from the normal direction to the main surface of the aerial imaging film 10, that is, the surface on which the plurality of dihedral reflective elements 11 are formed. Here, as described above, in the aerial imaging film 10, a large number of two-sided reflective elements 11 having substantially the same shape are regularly arranged in the vertical and horizontal directions. Here, among the light emitted from O1 with a specific point of a certain projection object as the starting point O1, light L11 is the second reflected light of a specific two-sided reflective element 11p among the many two-sided reflective elements 11. The light L12 is specularly reflected on the surface 11b at a reflection point R1, and the reflected light L12 is further specularly reflected on the first reflection surface 11a at a reflection point R2. After that, the reflected light L13 finally reaches the original center point O1 and the imaging point O2, which is the same point in FIG. 4(c). However, the starting point O1 of L11 in space and the imaging point O2 through which the reflected light L13 passes are in a plane-symmetrical positional relationship with respect to the formation surface of the plurality of dihedral reflective elements 11 of the aerial imaging film 10. has.

Next, a description will be given of light L21, which is different from light L11, among the lights emitted from the starting point O1, which is a specific point on the object to be projected. The light L21 is also specularly reflected at the reflection point R3 on the second reflective surface 11b of a specific two-sided reflective element 11q different from the aforementioned two-sided reflective element 11p among the many two-sided reflective elements 11, and the reflected light L22 Further, the light is specularly reflected on the first reflecting surface 11a at a reflection point R4. After that, the reflected light L23 finally reaches the above-mentioned imaging point O2.

In this way, the aerial imaging film 10, in which a large number of dihedral reflective elements 11 having substantially the same shape are regularly arranged in the vertical and horizontal directions, allows light rays emitted from an object placed in a certain direction to pass through the optical element. When the light is incident on the two-sided reflective element 11, it is reflected twice on the first reflective surface 11a and the second reflective surface 11b, which are the two reflective surfaces of the two-sided reflective element 11, once each. As a result, an image of the object to be projected is formed at a position symmetrical to the surface of the object to be projected with respect to one surface of the aerial imaging film 10.

(b) Information Display Device Next, the information display device 200, which is a constituent device of the security document inspection system of this embodiment, will be explained. FIG. 5(b) is a configuration diagram regarding the configuration of the information display device 200. The information display device 200 mainly includes a control section 211, an interface section 214, an antenna 215, a power supply section 213, a display driving section 216, and a display section 202. Further, although it is preferable that the information display device 200 includes a storage unit 212, it is not necessarily necessary.

The control unit 211 has a function of performing various calculations, judgments, and commands, and may be, for example, a personal computer or a smartphone. The antenna 215 is necessary for transmitting and receiving radio waves for non-contact communication at a predetermined frequency with the above-mentioned combined body 8. Further, the interface section 214 has a function of encoding necessary information from received radio waves and converting information to be transmitted into transmission radio waves. The power supply unit 213 supplies power necessary for the operation of the control unit 211, display drive unit 216, display unit 202, etc., and may be of a type with a built-in battery or a type that supplies power from an external source using an AC adapter. Any configuration is possible.

The display driving unit 216 has a function of receiving instructions of information to be displayed from the control unit 211 and controlling the display unit 202 to perform necessary display. This can be realized by, for example, a control unit of a projector, a personal computer, a smartphone, or the like. Further, the display unit 202 is a medium that actually displays information instructed by the control unit 211 and the display driving unit 216 on a display. This can also be realized, for example, by a display unit of a projector, a personal computer, a smartphone, or the like. Further, the control section 211 may also have the function of the display driving section 216.

The information displayed on the display unit 202 is, for example, information on the face photo 3 of the passport owner, which the information display device 200 reads from the combination 8 of the security document 1. However, the information may be character information such as the name, date of birth, or unique number associated with the owner of the other passport. In other words, it may be the unique information of the passport owner itself. Alternatively, it may be related information associated with these unique information. Related information is, for example, information that cannot directly generate unique information itself, but can identify unique information, and can indirectly generate unique information by referencing another storage device, database, table, etc. This is information that can be identified.

In this way, the information display device 200 may have a mode in which the unique information read from the combined body 8 is directly displayed on the display unit 202 as being the same as the specific information corresponding to the unique information. In addition, based on the related information read from the combination body 8, by referring to its own storage device, database, table, removable storage medium such as an IC card or USB memory, or an external database by connecting to a network, etc. The specific information may be displayed on the display unit 202 as being the same as the specific information corresponding to the specific information.

Alternatively, the information display device 200 performs predetermined editing, processing, and addition on the unique information read from the combination 8 or the unique information specified from the related information, and converts this into the specific information corresponding to the unique information. The specific information may be displayed on the display unit 202. In contactless communication with the combination body 8, the information display device 200 preferably verifies the validity of the security document 1 by going through a mutual authentication process using a predetermined encryption key or the like.

Such information display device 200 may be configured as a single device, or may be configured as a system by connecting a plurality of devices. For example, it can be configured by combining a personal computer, a non-contact reader/writer, and a display, or it can be configured by a smartphone alone with a non-contact communication function with the combined body.

(c) Security Document Inspection Method Next, the security document 1 inspection method using the security document inspection system 100 including the security document 1 and the information display device 200 described above and its functions will be explained based on FIG. 6 and the like. do. FIG. 6 is a flow diagram showing the inspection work of the secure document 1.

(i) Placement of the secure document in a predetermined position First, as schematically shown in FIG. The security document 1 is fixed in a predetermined position in the space above the information display device 200 using a fixing jig (not shown) so that it is fully opened from the page 2 (S301). As will be described later, the aerial image 80 is formed at a position that is symmetrical to the display unit 202 of the information display device 200 with respect to the aerial image film 10 of the information page 2, as shown in FIG. In consideration of the fact that the information page 2 will be imaged, it is necessary to calculate backward from the location where the aerial image 80 is to be displayed and specify the fixed position and inclination of the information page 2.

(ii) Non-contact communication between the information display device and the IC chip Next, using the communication function of the information display device 200, non-contact communication with the IC chip 72a is established. Specifically, in accordance with the NFC standard or other communication standards, the information display device 200 is placed in a state where necessary instructions can be sent to the combination 8 and information returned from the combination 8 can be received. (S302).

(iii) Reading unique information etc. from the IC chip by the information display device Next, the information display device 200 uses the non-contact communication function to read the unique information recorded in advance on the IC chip 72a or the like from the combination body 8. The related information associated with is read out (S303). Normally, the IC chip 72a built into the security document 1 such as a passport records unique information and related information displayed on the information page 2 in order to improve the reliability of determining the authenticity of the information page 2.

(iv) Display of specific information on display section Next, the information display device 200 displays the specific information corresponding to the specific information or the related information from the specific information read from the combination 8 or the related information associated therewith. The information is determined and displayed on the display unit (S304). The specific information may directly refer to specific information read from the combination 8 or specific information specified from related information associated therewith. Further, the specific information may refer to specific information read from the combined body 8 or specific information specified from related information that has been edited, processed, or added in a predetermined manner. That is, the specific information is a concept that includes the specific information itself and the specific information converted into a format suitable for display.

(v) Generation of an aerial image forming image corresponding to the image on the display unit The image of the specific information displayed on the display unit 202 of the information display device 200 is generated as a projection object on the aerial image forming film 10 of the information page 2. By passing through the second reflection, an aerial image 80 is generated in a predetermined space near the security document 1, as shown in FIGS. 1 and 2 (S305). When the image on the display unit 202 is an object to be projected, the light rays emitted from the object are projected by the aerial imaging film 10 to a plane-symmetrical position of the object with respect to one surface of the aerial imaging film 10. An aerial image 80 is generated as an image corresponding to the projected object. A worker such as an inspector can easily determine the authenticity of the security document 1 by comparing this aerial image 80 with the information displayed on the information page 2 of the security document 1 fixed in the vicinity. can be done.

As described above, various effects can be achieved by employing the information page 2, the security document 1, the security document inspection system 100, and the security document inspection method of the first embodiment of the present disclosure. For example, in this embodiment, it is possible to use unique information and related information regarding display information of an information page, which is often recorded in advance on the IC chip of the combined body. Therefore, there is no need to record new additional information for inspection on the IC chip, and it is possible to suppress an increase in the load on the process of manufacturing and issuing security documents.

Furthermore, in this embodiment, it is possible to easily visually compare the unique information recorded on the IC chip and the unique information displayed on the information page. For example, the comparison target of the unique information can be a facial photograph or name information. Such information that is easy to visually determine helps reduce the burden of authentication work without having to check with various other information. Furthermore, when determining the authenticity of facial photographs as unique information, especially in passports, etc., three parties are required: the owner of the security document, the facial photograph information printed on the security document, and the facial photograph image formed in the air. Direct visual verification makes it easy to authenticate the person and determine the authenticity of the security document, and it is possible to obtain extremely high anti-counterfeiting effects.

2. Second Embodiment Next, a second embodiment of the information page, security document, etc. of the present disclosure will be described. As shown in FIGS. 1 and 2, the security document 1a of this embodiment has almost the same appearance as the security document 1 of the first embodiment. Further, the point that a predetermined aerial image 80 can be obtained using the information display device 200 is also the same as in the first embodiment. Moreover, FIG. 7(a) is a side sectional view of the information page 2a of this embodiment, which corresponds to the information page 2 of FIG. 3(a). The difference between the information page 2a according to the second embodiment and the first embodiment is that the transparent window 41 is made of a transparent material in the thickness direction of the information page 2a, such as a first transparent window 41a and a second transparent window 41b. The aerial imaging film 10a is formed between the first transparent window 41a and the second transparent window 41b.

As shown in FIG. 7A, for example, if the aerial imaging film 10a is formed approximately at the center of the first transparent window 41a and the second transparent window 41b in the thickness direction of the information page 2a, , the first transparent window 41a is provided to penetrate the white layer 15 and the core layer 16, and the second transparent window 41b is provided to penetrate the intermediate layer 17, the IC module holding layer 18, and the additional intermediate layer 19. It will be done. In this case, if an attempt is made to take out the aerial imaging film 10a sandwiched between the first transparent window 41a and the second transparent window 41b for forgery, almost all layers of the information page 2a will be destroyed. This makes counterfeiting of the aerial imaging film 10a even more difficult. Furthermore, since both surfaces of the information page 2a of the aerial imaging film 10a are protected by the transparent windows 41, damage to the aerial imaging film 10a due to external forces is suppressed.

3. Third Embodiment Next, a third embodiment of the information page, security document, etc. of the present disclosure will be described. As shown in FIGS. 1 and 2, the security document 1b of this embodiment also has an appearance that is almost the same as the security document 1 of the first embodiment, and the function using the information display device 200 is also the same as that of the security document 1b of the first embodiment. This is similar to the embodiment. Further, FIG. 7(b) is a side sectional view of the information page 2b of this embodiment, which corresponds to the information page 2 of FIG. 3(a). Note that the symbols of members similar to those in FIG. 7(a) are omitted as appropriate. The difference between the information page 2b according to the third embodiment and the first embodiment is that the aerial imaging film 10b has more unique information such as the facial photograph 3 than the transparent window 42 in the thickness direction of the information page 2b. is formed on the side far from one surface of the displayed information page 2, that is, on the side close to the second outer surface transparent layer 20.

With such a configuration, the aerial imaging film 10b is provided in the through hole of the additional intermediate layer 19 adjacent to the IC module holding layer 18, and the aerial imaging film 10b can be used for counterfeiting. If an attempt is made to take it out, there is a high possibility that the IC module holding layer 18 adjacent to the additional intermediate layer 19 and the IC module 7 will be destroyed. This makes counterfeiting of the aerial imaging film 10b more difficult. Furthermore, since the aerial imaging film 10b is placed in a recessed place when viewed from the surface on which the unique information such as the face photo 3 of the information page 2b is displayed, the aerial imaging film 10b is protected by the transparent window 42. You can expect good results.

Furthermore, since the aerial imaging film 10b can be placed slightly closer to the position of the display section 202 of the information display device 200 disposed below, the imaging position of the aerial imaging image 80 can be moved closer to the security document 1b. It can be brought close to the side.

4. Fourth Embodiment Next, a fourth embodiment of the information page, security document, etc. of the present disclosure will be described. As shown in FIGS. 1 and 2, the security document 1c of this embodiment also has an appearance that is almost the same as the security document 1 of the first embodiment, and the function using the information display device 200 is also the same as that of the security document 1c of the first embodiment. Similar to embodiment. Moreover, FIG. 8 is a side sectional view of the information page 2c of this embodiment, which corresponds to the information page 2 of FIG. 3(a). The difference between the information page 2c according to the fourth embodiment and other embodiments is that the aerial imaging film is divided into a first aerial imaging film 10c and a second aerial imaging film 10d, and information on these The layout positions of the pages 2c in the thickness direction are shifted from each other. Furthermore, when the information page 2c is viewed in plan, the first aerial imaging film 10c and the second aerial imaging film 10d are arranged in an area that overlaps at least the transparent window 43, but does not overlap with each other. There are also differences in points.

Note that in the area of the through hole on the same surface as the first aerial imaging film 10c where the first aerial imaging film 10c is not arranged, a first transparent window which is an auxiliary transparent window for filling the gap is provided. A partially transparent window 44a is arranged, and for the same purpose, a second A partially transparent window 44b is arranged.

With such a configuration, as shown in FIG. 2, the light beam L1 emitted from the display section 202 is reflected by two reflective elements on each of the first aerial imaging film 10c and the second aerial imaging film 10d. After repeated reflections, the light beam is emitted as a light beam L2, and an aerial image 80 is generated at the predetermined position. However, since the arrangement of the information page 2c in the thickness direction of the first aerial imaging film 10c and the second aerial imaging film 10d is shifted from each other, the The imaging position of the imaged image and the aerial image generated via the second aerial imaging film 10d will be slightly shifted. Therefore, by checking whether there is a slight shift in the imaging position of the aerial image, it is possible to determine the authenticity of the information page 2c or the security document 1c in more detail.

An application example of this embodiment will be explained. For example, in FIG. 8, with the transparent window 43 as a reference, the first aerial imaging film 10c is arranged above the left side of the page, and the second aerial imaging film 10d is arranged below the right side of the paper. This is the first pattern. Also, with the transparent window 43 as a reference, the first aerial imaging film 10c is placed below the left side, and the second aerial imaging film 10d is placed above the right side, which is opposite to the first pattern. The arrangement of is defined as the second pattern. Further, as in the first, second, and third embodiments, the third pattern is one in which the aerial imaging film is not arranged separately. At this time, the information pages and security documents of the first pattern, second pattern, and third pattern are created separately according to some conditions, and these are checked together when inspecting the security documents, so that the information Pages and security documents can be made more difficult to forge.

5. Fifth Embodiment Next, a fifth embodiment regarding an IC card of the present disclosure, which is different from a security document, will be described. FIG. 9A is a plan view of the IC card 400 of the fifth embodiment, viewed from the normal direction of its main surface, on the side where the external contact terminals 411 of the IC module 410 are arranged. Further, FIG. 9(b) shows that in the IC card 400 of FIG. 9(a), the IC card is 400 is a side cross-sectional view of a cross section taken along a plane perpendicular to the short side direction, as seen from the lower side of the page.

The IC card 400 illustrated in the fifth embodiment is a contact and non-contact IC card, and is also called a so-called dual interface card. However, the IC card 400 is not limited to this, and may be a contact type IC card or a non-contact type IC card. As shown in FIGS. 9(a) and 9(b), the IC card 400 has an aerial imaging film 10e visible in a partial area of the surface of the IC module 410 on the side where the external contact terminals 411 are arranged. It is configured so that it can be done. The aerial imaging film 10e has the same configuration as the aerial imaging film 10 of the first embodiment. Further, a through hole is formed in a predetermined range in the thickness direction of the IC card 400, and a transparent window 450 made of a transparent material and an aerial imaging film 10e are arranged therein.

Regarding the IC card 400 of this embodiment, as illustrated in the first to fourth embodiments, an inspection system can be constructed by combining it with the information display device 200, and it is possible to obtain an aerial image at a predetermined position. be. That is, in FIGS. 1 and 2, the arrangement of the information page 2 of the security document 1 can be replaced with the arrangement of the IC card 400. First, on the display unit 202 of the information display device 200, an image that is substantially the same as the owner's facial photograph 3 displayed on the face of the IC card 400 is displayed. As shown in FIG. 2, the image displayed on the display unit 202 is displayed on the display unit 202 with respect to the aerial imaging film 10e, due to the characteristics of the aerial imaging film 10e embedded in a part of the IC card 400. An aerial image 80 is generated at a position that is symmetrical with respect to the plane. That is, the light ray L1 emitted from the display unit 202 is repeatedly reflected twice by the later-described two-sided reflective element of the aerial imaging film 10e, and is then emitted as the light ray L2 to generate the aerial image 80 at the predetermined position. do.

This aerial image 80 is visually recognized by the worker as an image "standing out in the air" near the IC card 400, as an image that is substantially the same as the owner's face photo 3 when viewed from the direction V in FIG. be able to. In this way, the worker can visually recognize the aerial image 80 that is substantially the same as the owner's face photo 3 in the air near the owner's face photo 3 displayed on the face of the actual IC card 400. . Therefore, the operator can easily visually confirm the similarity between the aerial image 80 and the facial photograph 3. Next, details of each configuration of the IC card inspection system will be explained below.

(a) Card base The card base 401 refers to members in a card state excluding the IC module 410. Typically, as shown in FIG. 9(b), from the bottom in the thickness direction, an oversheet layer 405, a core The layer 404, the core layer 403, and the oversheet layer 402 are laminated in this order. Further, between the core layer 404 and the core layer 403, an antenna 440 wound in a loop shape and made of a coated conducting wire or the like is arranged. Furthermore, antenna end portions 440a and 440b are formed at both ends of the antenna 440.

However, the layer structure of the card base 401 is not limited to this, and may include a three-layer structure of an oversheet layer, a core layer, and an oversheet layer, a two-layer structure of a core layer, and an antenna layer. A five-layer structure including a core layer, a core layer, and an oversheet layer may be used. Further, the surface of the oversheet layer 402 or 405 of the card base 401 on the side opposite to the core layer 403 or 404 may be printed or embedded with a magnetic stripe. The surface adjacent to the surface may be printed.

(i) Core layer As the core layers 403 and 404, a wide variety of white or colored plastic sheets can be used, and the following individual films or composite films thereof can be used. For example, polyethylene terephthalate (PET), PET-G (terephthalic acid-cyclohexanedimethanol-ethylene glycol copolymer), polyvinyl chloride, vinyl chloride-vinyl acetate copolymer, polycarbonate, polyamide, polyimide, cellulose diacetate, cellulose These include triacetate, polystyrene, ABS, polyacrylic acid ester, polypropylene, polyethylene, polyurethane, and the like. The thickness of the core sheet can be appropriately selected in consideration of the overall thickness of the card, and can be, for example, about 0.25 mm or more and 0.38 mm or less. Note that, as described later, it is necessary to arrange the antenna 440 on the surface of either the core layer 403 or 404 so that it is sandwiched between both core layers.

Note that one or both of core layers 403 and 404 may be a laser beam printing layer. Alternatively, the core layer 403 and the like may be further divided into a plurality of layers, and a laser beam printing layer may be laminated on a part of the layers. The laser light printing layer is colored and blackened by the irradiated laser light, and can display desired characters. The laser beam printing layer has polycarbonate containing a laser beam coloring accelerator, and by irradiating the laser beam printing layer with a laser beam, the laser beam coloring accelerator has thermal energy. In this case, the carbon contained in the polycarbonate that is in contact with the laser light coloring accelerator burns and turns black, thereby displaying characters.

(ii) Oversheet layer The oversheet layers 402 and 405 are usually made of the same material as the core layer, but a transparent material with a thickness of approximately 0.05 mm or more and 0.10 mm or less may be used. preferable. From the viewpoint of preventing the occurrence of curling when the laminate of the core layer and oversheet layer is integrated by heat pressing or the like, it is preferable that the thicknesses of the oversheet layers 402 and 405 are the same, but they are not necessarily the same. You don't have to. The material for the oversheet layer may be any material as long as it has heat-adhesive properties, but even if the oversheet layer itself does not have heat-adhesive properties, a layer of a known adhesive that generates adhesive force by heat etc. may be used. By additionally forming the layer between the core layer and the oversheet layer, the two can be integrated. In addition, when the IC card 400 is used as a magnetic card, a magnetic tape is embedded in advance by heat transfer or the like on the main surface side opposite to the core layers 403 and 404 for either or both of the oversheet layers 402 and 405. You can leave it there.

Note that one or both of oversheet layers 402 and 405 may be a laser beam printing layer. Further, in the present embodiment, a facial photograph 3 is displayed on the surface of the oversheet layer 402. This has a predetermined facial image transferred using a thermal transfer method. The face image may be drawn using a laser beam. Alternatively, a hologram may be formed by thermal transfer on one or both of oversheet layers 402 and 405.

(iii) Antenna The antenna 440 built into the card base 401 in FIGS. 9(a) and 9(b) may be one that performs close proximity communication using, for example, the 13.56 MHz HF frequency band, or For example, the IC chip 413a may be arranged to communicate with an external reader/writer (information reading/writing device) when performing contactless communication. When the IC card 400 is held over the reader/writer, a current is generated by the antenna 440 due to a magnetic field generated by the reader/writer, and the antenna 440 supplies power to the IC chip 413a. This enables the IC chip 413a to be driven, and when performing contactless communication, transmits and receives information to and from the reader/writer, rewrites information, and the like.

Antenna 440 is typically formed of a covered conductor wire that is a copper wire whose periphery is coated with an insulating material. In addition, copper alloy wires such as Cu-Ni, Cu-Cr, Cu-Zn, Cu-Sn, and Cu-Be, or various metal wires and metal alloy wires such as iron, stainless steel, and aluminum can be selected. You can also. By using a coated conducting wire, the IC card 400 can be formed at a lower cost than, for example, a copper foil etching method. However, the antenna 440 may be formed by etching copper foil, aluminum foil, or the like.

(iv) Transparent Window In FIG. 9(b), a transparent window 450 made of a transparent material and an aerial imaging film 10e are provided in the thickness direction of the card base 401, penetrating the core layers 403 and 404.

(v) Aerial Imaging Film When the IC card 400 is viewed in plan from the direction normal to the main surface of the IC card 400, the aerial imaging film 10e is formed at least in a region overlapping with the transparent window 450. Further, the aerial imaging film 10e is placed on the side closer to one surface of the IC card 400 on which unique information such as the face photo 3 is displayed than the transparent window 450 in the thickness direction of the IC card 400, that is, the oversheet. It is formed on the side closer to layer 402. Note that the configuration of the aerial imaging film 10e and the function of generating an aerial image by reflecting an image as a projection object are the same as those of the aerial imaging film 10 of the first embodiment, so detailed explanations will not be provided. Explanation will be omitted.

(b) IC module, etc. Next, an IC module storage space 415, which is a concave portion, is formed in the card base by cutting to obtain a cut card base 401, and then the IC module 7, etc., is embedded and fixed therein. I will explain about it. The IC module 7 is embedded and fixed after a predetermined conductive adhesive 412 and 413 is applied or pasted to a predetermined position in an IC module storage space 415 formed in the card base 401, so that the IC chip 413a and Electrical connection with the antenna 440 can be achieved.

As shown in FIG. 9(a), the IC module 7 includes an approximately rectangular flat board 412 with rounded corners, an external contact terminal 411 on one surface, and connection terminals 414a and 414b on the other surface. At the same time, an IC chip body 413, which is a protruding portion, is formed by a sealing resin 413b that covers the IC chip 413a together with the wires. Each of the main components of the IC module 7 will be explained below.

(i) Substrate The substrate 412 is a flexible resin film made of glass epoxy resin, polyimide resin, etc., with copper foil pasted on the front and back sides of the resin film via an adhesive, and the copper foil pasted on the front and back surfaces of the resin film. are left to form a predetermined pattern. Specifically, a photosensitive material was applied and a predetermined pattern was formed so as to form external contact terminals 411 on one copper foil surface of the resin film and connection terminals 414a and 414b on the other copper foil surface. By sequentially placing the film plate, exposing it to light, and etching and removing non-photosensitive areas, a substrate 412 with a predetermined pattern of copper foil partially remaining on the front and back surfaces of the resin film is formed. Further, the substrate 412 is provided with a plurality of through holes (not shown) in advance for wire bonding to the external contact terminals 411.

(ii) IC Chip An IC chip 413a is bonded and fixed to the surface of the substrate 412 opposite to the surface on which the external contact terminals 411 are formed via an adhesive. The IC chip 413a includes a CPU for controlling operations of both contact and non-contact communications, a storage device such as RAM, EEPROM, and flash memory, and decoding of input signals and generation of output signals for contact and non-contact communications. It is equipped with various circuits such as interface circuits and power generation circuits. Note that the various circuits may be provided as separate elements from the IC chip. The IC chip 413a is adhesively fixed to the center of the surface of the substrate 412 on which the connection terminals 414a and 414b are formed, and the pads on the circuit surface of the IC chip 413a and the terminal sections of the external contact terminals 411 are connected by a wire such as a gold wire passing through a through hole in the substrate 412. Further, the pads of the IC chip 413a and the connection terminals 414a and 414b of the substrate 412 are similarly connected with wires.

(iii) Sealing resin, IC chip body The mounting surface of the IC chip 413a of the substrate 412 on which the above-mentioned IC chip 413a is mounted and the wires are connected protects the IC chip 413a and the wires from external force loads and environmental loads. Therefore, these are covered with a sealing resin 413b, and an IC chip body 413, which is a protruding portion, is formed. As the sealing resin 413b, an ultraviolet curable resin, a thermosetting resin, or the like is used.

(iv) Conductive Adhesive The IC module storage space 415, which is a recess for embedding the IC module 7, embeds and fixes the above-mentioned IC module 7 in the card base 401 formed by cutting with an end mill. The conductive adhesive used for connection will be explained. The conductive adhesives 412 and 413 are liquid or tape-like adhesives that are applied or pasted above the antenna end 414a in the thickness direction of the card base 401, as shown in FIG. 9(b). .

As such a conductive adhesive, a so-called conductive paste in which silver particles are dispersed as a filler in an epoxy resin can be used as a liquid, and in particular, ACP ( Anisotropic conductive paste) can also be used. Moreover, ACF (anisotropic conductive film) can be used as the tape-like adhesive. When forming the IC module storage space 415 in the card base by cutting with an end mill, the cutting depth is partially changed so that the antenna ends 440a and 440b are exposed in the IC module storage space 415.

Next, conductive adhesives 412 and 413 are applied or pasted above the exposed antenna ends 440a and 440b. Thereafter, the IC module 7 is mounted on this, and a predetermined heat pressure is applied from the surface of the external connection terminal 411 using a heat block. As a result, the conductive adhesives 412 and 413 are thermally cured, and the antenna end 440a and the connection terminal 414a are electrically connected via the conductive adhesive 412. Similarly, the antenna end portion 440b and the connection terminal 414b are also electrically connected via the conductive adhesive 413. In this way, IC card 400 is manufactured.

(c) Information Display Device The information display device 200, which is a constituent device of the IC card inspection system of this embodiment, is the same as that described in the first embodiment, and detailed explanation will be omitted. However, the step in which the information display device 200 communicates with the IC chip 413a of the IC card 400 and reads out the unique information or related information associated therewith from the IC chip 413a (S303 in FIG. 6 described above) is not necessarily a non-standard step. It is not limited to contact communication. For example, when the IC card 400 is a contact and non-contact shared IC card, or a contact IC card, the communication between the information display device 200 and the IC chip 413a of the IC card 400 may be contact communication, for example, The communication may be performed by wired communication that complies with the ISO7816 standard.

(d) IC card inspection system and inspection method The IC card inspection system of this embodiment uses the IC card 400 and the information display device 200 to inspect the security document 1 or the information shown in FIGS. 1 and 2 as described above. A similar configuration can be adopted by replacing the information page 2 with an IC card 400. Moreover, the inspection of the IC card can also be carried out in the same manner as described based on the configuration diagram of FIG.

As described above, by employing the IC card 400, the IC card inspection system, and the IC card inspection method of the fifth embodiment of the present disclosure, various effects can be achieved as with the security documents of other embodiments. can play. For example, it is possible to use unique information or related information regarding display information of an IC card, which is often recorded in advance on the IC chip of an IC card. Therefore, there is no need to record new additional information for testing on the IC chip, and an increase in the load on the IC card manufacturing and issuing process can be suppressed.

Furthermore, in this embodiment, it is possible to easily visually compare the unique information recorded on the IC chip and the unique information displayed on the IC card. For example, the comparison target of the unique information can be a facial photograph or name information. Such information that is easy to visually determine helps reduce the burden of authentication work without having to check with various other information. In particular, when the IC card is a driver's license or credit card, when determining authenticity using a face photo as unique information at a checkpoint or when paying at a store, it is necessary to identify the owner of the IC card and the information printed on the IC card. By directly and visually comparing the facial photo information and the facial photo image formed in the air, it is easy to authenticate the person and determine the authenticity of the IC card, and an extremely high anti-counterfeiting effect can be obtained.
