  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the drawings attached to the present specification, for the sake of illustration and ease of understanding, the scale, the vertical / horizontal dimension ratio, and the like are appropriately changed and exaggerated from those of the actual product.

  1-18 is a figure for demonstrating one embodiment of this invention. Among these, FIG. 11 to FIG. 18 are diagrams for explaining a manufacturing method and a manufacturing apparatus of a personal information display body according to an embodiment of the present invention. FIG. 1 to FIG. FIG. 19 is a diagram for explaining an example of a personal information display body that can be manufactured by the manufacturing method and the manufacturing apparatus of FIGS.

  As shown in FIG. 1, the personal information display 10 is a medium on which personal information is recorded. Specific applications of the personal information display 10 can include passports, driver's licenses, health insurance cards, cash cards, credit cards, employee cards, membership cards, and the like. Here, the personal information recorded on the personal information display 10 is information related to an individual, and is typically information related to a specific person who is given the personal information display 10. This personal information is not limited to information widely used in general society such as name, date of birth, gender, etc., but related to individuals used in connection with specific organizations such as employee numbers and membership numbers. Information, information assigned to individuals only for a certain period, and the like are also included. Further, the personal information displayed by the personal information display 10 may be a part of information related to these individuals. Therefore, from the issuer of the personal information display 10, the personal information recorded on the personal information display 10 is information that must be individually handled for each personal information display 10 given to each individual. Become.

  Such a personal information display body 10 is given to the specific person, for example, in order to prove the identity or qualification of the specific person. The issuer of the personal information display body 10 can manage the owner of the personal information display body 10 based on the information displayed on the personal information display body 10. As a specific example, a certain organization, for example, a company gives a personal information display body 10, for example, an employee ID card, as a medium for proving that the organization belongs to the organization, for example, an employee of the company. . Based on the owner's personal information displayed by the personal information display 10, the organization manages entry / exit in the premises and indoors, specifically entry / exit restrictions, entry / exit records, and attendance management Etc. can be performed. Therefore, for the personal information display 10, it is easy to authenticate the owner, in other words, it is easy to determine the authenticity of the personal information display 10, and imitation and falsification are difficult. Requested.

  As shown in FIG. 1, the personal information display body 10 has a display element for displaying the personal information of a specific person to which the personal information display body 10 should be given. In the example shown in FIG. 1, the first to fourth display elements 41, 42, 43, 44 are provided in the personal information display 10, and in the other examples shown in FIGS. 2 and 3, Fifth display elements 411, 421, 43, 44, 45 are provided on the personal information display body 10. As shown in FIGS. 1 and 4, the personal information display 10 is formed in a card shape. The personal information display 10 includes a card-like display body 20 and a cover layer 34 stacked on the display body 20. The display elements 41, 42, 43, 44, 45 are provided in the display body main body 20 and are positioned between the display body main body 20 and the cover layer 34 or inside the display body main body 20.

  In the example described here, the display body 20 before the display element is formed has a common configuration among all the personal information display bodies 10 to be issued. As shown in FIG. 4, the display body 20 includes a first core layer 22 and a second core layer 23 that are stacked on each other and a first overprint printed on both sides of the core layers 22 and 23. A sheet layer 28 and a second oversheet layer 29. A first background print layer 25 and a second background print layer 26 are printed on the surfaces of the core layers 22 and 23, respectively.

  The background print layers 25 and 26 have patterns common to the issued personal information display 10 such as a background pattern except for a special case such as a mode in which personal information is recorded by laser engraving described later. Is the printed layer. The oversheet layers 28 and 29 function as a protective layer. In particular, in the example shown in FIG. 4, the second oversheet layer 29 forms the outermost surface of the card-like personal information display body 10. The oversheet layers 28 and 29 protect the patterns printed on the background print layers 25 and 26. The oversheet layers 28 and 29 may be colorless or colored in order to make the patterns printed on the background print layers 25 and 26 visible, but are preferably transparent or translucent. Further, the cover layer 34 provided on the first oversheet layer 28 may be colorless or colored so that the personal information displayed by the display element and the pattern printed on the background print layer 25 can be visually recognized. It is translucent.

  Each layer and the cover layer 34 constituting the display body 20 can be produced by a known method using a known material used for a card body of an ID card, for example. However, the first oversheet layer 28 of the display body 20 that forms the surface on which the display elements 41, 42, 43, 44, 45 are formed has the display elements 41, 42 as shown in FIGS. 5 to 7. , 43, 44, 45 can take various forms. This point will be described later in correspondence with the description of the display elements 41, 42, 43, 44, 45.

  Next, the display elements 41, 42, 43, 44, and 45 will be described in detail. As described above, the personal information display 10 includes display elements 41, 42, 43, 44, and 45 for displaying personal information of a specific person who should be the owner of the personal information display 10. 20 or inside the display body 20. The cover layer 34 laminated on the first oversheet layer 28 of the display body 20 covers the display elements 41, 42, 43, 44, 45 and protects the display elements 41, 42, 43, 44, 45.

  In the example shown in FIG. 1, the first display element 41 and the second display element 42 display the upper body including the face as an image of a specific person. The third display element 43 displays the identification number as symbol information such as letters and numbers. The fourth display element 44 displays the name, gender, date of birth as character information. When the personal information display 10 displays an image of the owner, particularly an image including a face, as in the illustrated example, the authentication of the owner and the personal authentication of the personal information display based on the authentication result are performed. It can be done easily and accurately.

  The first display element 41 is formed using the diffractive optical variable element 50. Here, the diffractive optically variable image device (DOVID) 50 is an element whose observation method, for example, brightness, color, or the like changes depending on the observation direction by using a diffraction phenomenon. As a typical example of the diffractive optical variable element 50, a hologram and a diffraction grating can be exemplified. The diffractive optical variable element 50 formed of a hologram or a diffraction grating may be formed as a relief type or may be formed as a volume type. In the case of the relief type diffractive optical variable element 50, since it is realized by forming irregularities on the optical element, it can be manufactured relatively easily. On the other hand, in the case of the volume type diffractive optical variable element 50, since a very advanced manufacturing technique is required, the forgery prevention property can be improved. The diffractive optical variable element 50 made of a hologram or a diffraction grating may be a transmission type or a reflection type. In the case of the reflective diffractive optical variable element 50, the core layers 22 and 23 and the background print layers 25 and 26 may not be formed transparently. The diffractive optical variable element 50 may be opaque, or may be transparent or translucent regardless of color or colorless.

  As a specific example, in the personal information display body 10 shown in FIG. 10, the diffractive optical variable element 50 is provided on the first oversheet layer 28 of the display body 20 via the bonding layer 56. The diffractive optical variable element 50 is configured as a relief type computer-generated hologram or diffraction grating. As shown in FIG. 10, the diffractive optical variable element 50 includes a concavo-convex forming layer 52 having a concavo-convex surface and a reflective layer 54 covering the concavo-convex surface of the concavo-convex forming layer 52. The unevenness forming layer 52 is formed using, for example, a transparent resin. On the other hand, the reflective layer 54 can be formed as a thin film deposited on the concavo-convex surface of the concavo-convex forming layer 52. The reflective layer 54 can be formed using a metal-containing material having a refractive index different from that of the unevenness forming layer 52, such as titanium oxide, zinc sulfide, and tin oxide. The reflective layer 54 does not need to be opaque, and may be transparent or translucent.

  The first display element 41 displays personal information according to the arrangement pattern of the diffractive optical variable element 50. For example, by transferring the sheet-like diffractive optical variable element 50 in a desired arrangement pattern, the first display element 41 can display personal information grasped depending on the arrangement pattern of the diffractive optical variable element 50. it can. In other words, according to the personal information display 10 described here, the first display element 41 has the specific information of the specific person, typically, depending on the arrangement pattern of the diffractive optical variable element 50 that requires advanced manufacturing technology. The personal information of the owner of the personal information display body 10 is displayed. Thus, since the 1st display element 41 is formed using the diffractive optical variable element 50, forgery of the personal information display body 10 can be made difficult. On the other hand, since it is only necessary to display the personal information in the arrangement pattern of the diffractive optical variable element 50, it is not necessary to record the personal information on the diffractive optical variable element 50 itself, for example, as an uneven structure or interference fringes. Therefore, the personal information display 10 can be manufactured relatively easily and can exhibit excellent anti-counterfeiting properties.

  In addition, in the example shown in FIG. 1, the first display element 41 displays an image of a specific person who should become the owner of the personal information display body 10 by the arrangement pattern of the diffractive optical variable element 50. In general, in order to authenticate the owner of the personal information display body 10 based on the personal information display body 10, it is preferable that an image of the owner, particularly a face, is displayed on the personal information display body 10. When the image of the owner, in particular, the face is recorded on the personal information display body, the authentication of the owner and the authenticity determination of the personal information display body 10 based on the authentication result can be easily and accurately performed. . In particular, according to the example described here, the first display element 41 displays the image of the owner, particularly the face, by the arrangement pattern of the diffractive optical variable element 50 that requires advanced manufacturing techniques. Therefore, the personal information display body 10 that can be manufactured relatively easily can be provided with extremely excellent anti-counterfeiting properties, and the authentication of the owner using the personal information display body 10 and the personal information The authenticity determination of the display body 10 can be performed very easily and accurately.

  The diffractive optical variable element 50 itself has a pattern that does not display personal information. The pattern possessed by the diffractive optical variable element 50 itself is not limited to the one showing specific information or meaning the specific information, and is not particularly limited to the arrangement of figures, characters, symbols, marks and the like, the pattern, the pattern and the like. That is, the diffractive optical variable element 50 can display the personal information of a specific person according to the arrangement pattern, but the diffractive optical variable element 50 itself may display a pattern unrelated to the personal information. . Therefore, the pattern possessed by the diffractive optical variable element 50 itself is common to all the issued personal information display bodies 10 irrespective of the personal information to be displayed using the diffractive optical variable element 50. Can do. Thereby, the personal information display body 10 can be produced more easily.

  In addition, a minute concealment image can be included in a pattern irrelevant to the personal information displayed by the diffractive optical variable element 50 itself. In this case, it is possible to give a better anti-counterfeiting property to the personal information display 10 that can be manufactured relatively easily, and it is very easy and more accurate to determine the authenticity of the personal information display. It can be carried out.

  As shown in FIGS. 8 and 9, the diffractive optical variable element 50 has a gradation of binary or higher for each of the plurality of unit regions 48 defined on the surface on which the first display element 41 is to be provided. Can be arranged in In this case, the first display element 41 is formed as an aggregate of diffractive optical variable elements 50 arranged in the predetermined unit region 48. In the binary gradation, as shown in FIG. 8, the plurality of unit regions 48 are divided into two types: a region where the diffractive optical variable element 50 is disposed and a region where the diffractive optical variable element 50 is not disposed. Is done. In the example shown in FIG. 8, the surface on which the first display element 41 is to be provided, for example, the surface of the display body 20 in FIGS. 5 to 7 is divided into a matrix and arranged in a grid adjacent to each other. A plurality of unit regions 48 are defined. According to this embodiment, personal information can be displayed with excellent design by the first display element 41 using the diffractive optical variable element 50.

  Furthermore, as shown in FIG. 9, if the arrangement of the diffractive optical variable elements 50 in each unit region 48 is determined with three or more gradations greater than binary, an excellent design is achieved by the first display element 41. Personal information can be displayed by gender. For example, as shown in the figure, the first display element 41 can clearly display an image of the owner of the personal information display body, particularly a face image, in many gradations. As a result, the personal information display body 10 that can be manufactured relatively easily can be provided with a better anti-counterfeit property, and the personal information display body 10 can be authenticated and the personal information display can be performed. The authenticity determination of the body 10 can be performed very easily and more accurately. It should be noted that various known methods such as dithering can be employed as a method for realizing gradations having more than binary values.

  As an example, in the example shown in FIG. 9, the unit area 48 is divided into four sub-unit areas 49. Whether or not the diffractive optical variable element 50 is arranged is determined for each sub-unit region 49. As a result, as shown in FIG. 9, the plurality of unit regions 48 include a zero-stage region 48 a in which none of the four sub-unit regions 49 is provided with the diffractive optical variable element 50 and four sub-unit regions 49. The diffractive optical variable element 50 is provided in the one-stage region 48b in which the diffractive optical variable element 50 is provided only in one of the sub unit regions 49, and the two sub unit regions 49 of the four sub unit regions 49. The two-stage region 48c, the three-stage region 48d in which the diffractive optical variable element 50 is provided in three of the four subunit regions 49, and the four subunit regions 49 are diffracted. And a four-step region 48e where the optical variable element 50 is provided. In other words, in the example shown in FIG. 9, the first display element 41 is formed as a collection of diffractive optical variable elements 50 arranged in each of the plurality of unit regions 48 with a five-value area gradation. The personal information is displayed by the arrangement pattern of the aggregate of the diffractive optical variable elements 50 arranged in the area gradation.

  Note that the first display element 41 as an aggregate of the diffractive optical variable elements 50 arranged in the unit region 48 is obtained by attaching the diffractive optical variable element 50 formed in a sheet shape to the unit region 48 using an adhesive or the like. It can be produced by transferring. Typically, as will be described in detail later, the first display element 41 can be manufactured by thermal transfer using the thermal heads 62 and 67. In the example shown in FIG. 1, the arrangement of the diffractive optical variable elements 50 in each unit region 48 is controlled, and the human face is displayed by the controlled arrangement pattern of the diffractive optical variable elements 50. When the face is displayed as a so-called ghost image separately from the face displayed by the second display element 42 as in the example shown in FIG. 1, the size of the general ghost image in the ID card and In consideration of the number of pixels necessary for discriminating a human face with this size, the length of one side of the unit region 48 is preferably 20 μm or more and 300 μm or less. Transfer of the diffractive optical variable element 50 to the unit region 48 having such a size can be sufficiently realized by thermal transfer using a thermal head incorporated in a thermal transfer printer.

  Next, the second to fourth display elements 42 to 44 will be described. Similarly to the first display element 41, the second to fourth display elements 42 to 44 display personal information of a specific person who should own the personal information display body 10. As already described, in the personal information display 10 shown in FIG. 1, the third display element 43 displays the identification number as symbol information such as letters and numbers. The fourth display element 44 displays the name, sex, date of birth as character information. Similar to the first display element 41, the second display element 42 displays the upper body including the face of a specific person who should own the personal information display body 10. However, the second to fourth display elements 42 to 44 are formed without using a diffractive optical variable element. In other words, the second to fourth display elements 42 to 44 are different from the first display element 41 in at least one of the material used and the forming method.

  As described above, since the personal information display body 10 includes a plurality of display elements that are different in at least one of the material and the formation method, the forgery prevention property of the personal information display body 10 can be effectively enhanced. In addition, in the example shown in FIG. 1, the first display element 41 and the second display element 42 which are different in at least one of the material and the forming method both display the same personal information. In particular, the displayed personal information is an image of a person that facilitates authentication, and the first display element 41 as one display element exhibits excellent anti-counterfeiting properties as described above. In such a personal information display 10, first, based on a clear image displayed by the second display element 42, authentication of the owner of the personal information display 10 and authentication of the personal information display 10 are performed. The determination can be made more easily and accurately. In addition, by comparing the personal information displayed by the first display element 41 with the personal information displayed by the second display element 42, the authenticity determination of the personal information display body 10 can be performed more accurately. As a result, the personal information display body 10 has better anti-counterfeiting properties.

  The second to fourth display elements 42 to 44 can be manufactured by various known methods. As an example, the second to fourth display elements 42 to 44 can be formed on the display body 20 by transferring the coloring material to the first oversheet layer 28 of the display body 20 by sublimation heat transfer printing. it can. The color material thermally transferred to the display body 20 can include various colors corresponding to the second to fourth display elements 42 to 44 to be manufactured. In the personal information display 10 for displaying personal information by a full-color image, four color materials of yellow, magenta, cyan, and black, or four color materials of red, green, blue, and black are used. Will be thermally transferred. As a result, the diffractive optical variable element 50 and one or more of yellow, magenta, and cyan color materials, or one or more of red, green, and blue materials are formed between the display body 20 and the cover layer 34. A color layer 36 and a black layer 37 made of black are formed.

  In the personal information display body 10 shown in FIGS. 5 and 6, the second to fourth display elements 42 to 44 are formed from a color layer 36 and a black layer 37 provided on the display body 20 by thermal transfer printing. Yes. In the personal information display body 10 shown in FIG. 5, the first oversheet layer 28 of the display body 20 to which the color material is transferred includes a body layer 28a made of, for example, polyethylene terephthalate (PET) or polycarbonate (PC). A receiving layer 28b laminated on the main body layer 28a. In the example shown in FIG. 5, the color layer 36 is formed in the receiving layer 28b, and the black layer 37 and the diffractive optical variable element 50 are formed on the surface of the receiving layer 28b. On the other hand, in the personal information display 10 shown in FIG. 6, the first oversheet layer 28 to which the color material is transferred is a single material that can receive a dye that forms a color color material such as polychlorinated chloride (PVC). It is formed as a layer. Therefore, in the personal information display body 10 shown in FIG. 6, the color layer 36 is formed in the surface layer of the first oversheet layer 28, and the black layer 37 and the diffractive optical variable element are formed on the surface of the first oversheet layer 28. 50 is formed.

  As another example, at least one of the second to fourth display elements 42 to 44 can be formed by a laser engraving method. Further, the second to fourth display elements 42 to 44 may be formed by different methods. In the example shown in FIG. 7, the first oversheet layer 28 includes a main body layer 28 a that functions as a support material, and a laser coloring layer 28 c and a receiving layer 28 b that are sequentially stacked on the main body layer 28 a. Yes. A color material can be transferred to the receiving layer 28b by thermal transfer printing. Then, a black layer 37 along the scanning path of the laser light can be formed on the laser coloring layer 28c by irradiating the laser coloring layer 28c with a laser beam in a wavelength range in which the laser coloring layer 28c exhibits sensitivity. As yet another example, the first background print layer 25 of the display body 20 is formed as a laser coloring layer, and personal information is recorded on the first background print layer 25 of the display body 20 by a laser engraving method. You may make it do.

  By the way, although the personal information display body 10 has been described based on the example shown in FIG. 1, the personal information display body 10 shown in FIG. 1 can be manufactured according to the present embodiment. This is just one example. For example, the second to fourth display elements 42 to 44 may display personal information different from the example described above. Furthermore, instead of the first to fourth display elements 41 to 44 or in addition to the first to fourth display elements 41 to 44, other display elements may be provided on the personal information display body 10.

  Here, with reference to FIG. 2 and FIG. 3, another example of the personal information display 10 that can be manufactured according to the present embodiment will be described. The personal information display 10 shown in FIGS. 2 and 3 has first to fifth display elements 411, 421, 43, 44, 45. Among these, the first display element 411, the third display element 43, and the fourth display element 44 of the personal information display body 10 shown in FIGS. 2 and 3 are respectively the personal information display body 10 shown in FIG. The first display element 41, the third display element 43, and the fourth display element 44 are the same. Further, the fifth display element 45 of the personal information display 10 shown in FIGS. 2 and 3 is the same as the second display element 42 of the personal information display 10 shown in FIG. Each part of the personal information display 10 shown in FIGS. 2 and 3 is the same as the corresponding part of the personal information display 10 shown in FIG. 1 except for the second display element 421 described in detail below. It can be configured identically.

  In the personal information display body 10 shown in FIGS. 2 and 3, the second display element 421 displays personal information of a specific person who should own the personal information display body 10, similarly to the first display element 411. More specifically, like the first display element 411, the second display element 421 displays the upper body including the face of a specific person who should own the personal information display body 10. In particular, in the example shown in FIGS. 2 and 3, the image displayed by the second display element 421 displays the same image as the image displayed by the first display element 411 with the same size. Further, the image displayed by the first display element 411 and the image displayed by the second display element 421 overlap at the same position along the surface direction of the personal information display surface of the personal information display body 10. Is arranged.

  Since the first display element 411 and the second display element 421 manufactured by different methods are at least partially overlapped, forgery of the personal information display body 10 can be effectively made difficult. In particular, in the personal information display 10 shown in FIG. 2 and FIG. 3, the first display element 411 exhibits excellent anti-counterfeiting alone, as described above, and the first display element 411 has the first display element 411. The image and the image of the second display element 421 overlap and are observed. For this reason, forgery of the personal information display body 10 can be made extremely difficult. Further, since the first display element 411 and the second display element 421 can display the same personal information at the same position, the personal information displayed by the first display element 411 and the second display element 421 are displayed. It becomes possible to more accurately determine the authenticity of the personal information display body by comparison with the personal information to be displayed.

  In order to expect such an effect, it is preferable that at least one of the first display element 411 and the second display element 421 is formed to be transparent or translucent. For example, the first display element 411 is arranged on the surface side of the personal information display body 10, that is, the viewer side, and is formed to be transparent or translucent as described above, and the second display element 421 is the first display element. You may make it arrange | position to the back side of 411, ie, the inner side of the personal information display body 10. FIG. In this case, it becomes possible to observe the image displayed by the second display element 421 through the transparent or translucent first display element 411, and the effects described here can be obtained.

  In addition, in the personal information display body 10 shown in FIGS. 2 and 3, the second display element 421 may be formed using a fluorescent material. Here, the fluorescent light emitting material is a material that exhibits sensitivity to light in a certain wavelength range and emits light when receiving light in the wavelength range. According to such a personal information display 10, personal information displayed by the second display element 421 can be observed under special conditions. Under normal conditions, the second display element 421 It is possible to prevent the displayed personal information from being visually recognized.

  As an example, the second display element 421 may be manufactured using a fluorescent material that emits visible light when irradiated with invisible light such as infrared rays or ultraviolet rays. According to such a personal information display 10, since it contains personal information that cannot be displayed under normal conditions or is difficult to view, the forgery prevention property of the personal information display 10 can be greatly improved. . Further, since the image displayed by the first display element 411 can be observed more accurately under normal conditions, the owner can be authenticated and the authenticity determination of the personal information display can be performed more accurately. On the other hand, under a special environment where only the fluorescent light emitting material is irradiated with sensitive invisible light, only personal information displayed by the second display element 421 is observed as shown in FIG. . Thereby, the authentication of the owner and the authenticity determination of the personal information display body 10 can be easily and accurately performed also by the personal information image displayed by the second display element 421.

  Note that the second display element 421 can be manufactured by various known methods. As an example, the second display element 421 can be provided on the surface layer of the display body 20 or on the display body 20 by thermally transferring the fluorescent material to the first oversheet layer 28 by a thermal transfer printing method. Further, at least one of the display elements 42 to 44 of the personal information display body 10 shown in FIG. 1 and the display elements 43 to 45 of the personal information display body 10 shown in FIGS. The fluorescent color-developing layer 38 shown in FIGS. 5 to 7 may be formed using the described fluorescent light-emitting material.

  Next, a manufacturing method and a manufacturing apparatus according to an embodiment of the present invention capable of manufacturing the above-described personal information display body 10 will be described. The manufacturing method of the personal information display described here includes the step of preparing the display body 20 and the diffractive optical variable element region 85 of the thermal transfer sheet 80 so as to face the display body 20 to display personal information. By transferring the diffractive optical variable element 50 to the display body main body 20 in the obtained arrangement pattern, the color material is displayed in the process of providing the first display element 41 on the display body main body 20 and the arrangement pattern capable of displaying personal information And transferring the second to fourth display elements 42 to 44 to the display body main body 20 by transferring them to the body main body 20. On the other hand, as shown in FIG. 11, the personal information display manufacturing apparatus 60 arranges the diffractive optical variable element region 85 of the transfer sheet 80 so as to face the display body 20 and can display personal information. The transfer device 61 for transferring the diffractive optical variable element 50 to the display body main body 20 is provided, and the first display element 41 is provided on the display body main body 20 by the transfer device 61.

  First, the display body 20 can be manufactured by a known method. Specifically, the background printing layers 25 and 26 are printed on the core layers 22 and 23 described above, respectively, and a plurality of sheet-like materials that form the oversheet layers 28 and 29 are stacked on each other, thereby laminating. Create a body. Then, the display body 20 is obtained by cutting the obtained laminated body into a desired size. In addition, it is preferable from a viewpoint of production efficiency that the laminated body, which is an intermediate when the display body 20 is manufactured, is formed in such a size that a plurality of display bodies 20 having a desired size can be taken out.

  Next, the process of providing the first to fourth display elements 41 to 44 on the display body 20 and the transfer device 61 used in this process will be described mainly with reference to FIGS.

  First, the transfer device 61 will be described in detail. In the example shown in FIGS. 11 to 13, the second to fourth display elements 42 to 44 are provided on the display body 20 by transferring the color material to the display body 20 by thermal transfer printing. Similarly, the first display element 41 is provided in the display body 20 by transferring the diffractive optical variable element 50 to the display body 20 in a desired arrangement pattern by thermal transfer printing. In the example shown in FIG. 11, the transfer device 61 is configured as a thermal transfer device having a thermal head 62.

  The thermal transfer device 61 is configured as a so-called thermal transfer printer. In the illustrated example, the thermal transfer device 61 heats a support means 63 that supports a display body 20 as a transfer target, and a thermal transfer sheet 80 that is disposed on the support means 63 at a position facing the display body 20. A thermal head 62 that pressurizes, a thermal transfer sheet supply unit 64 that can supply the thermal transfer sheet 80 so that the diffractive optical variable element region 85 or the color material regions 81 to 84 face the display body 20 on the support unit 63, and have. The thermal transfer sheet supply means 64 has a feed roll 64a for feeding out the thermal transfer sheet 80 and a recovery roll 64b for collecting the thermal transfer sheet 80 after the thermal transfer. The thermal transfer sheet 80 fed from the feed roll 64a passes between the thermal head 62 and the support means 63 and is collected by the collection roll 64b. In the illustrated example, the display body 20 is supplied one by one from a display body supply means (not shown). The support means 63 is formed as a support table that supports a single card-like display body 20.

  FIG. 12 shows an example of the thermal transfer sheet 80 supplied from the thermal transfer sheet supply means 64. The illustrated thermal transfer sheet 80 includes a long base sheet 89 and a color material region 81 containing a color material for forming the second to fourth display elements 42 to 44 provided on the base sheet 89. , 82, 83, 84, a diffractive optical variable element region 85 for forming the first display element 41, and a cover layer region 86 for forming the cover layer 34. In the illustrated example, as a color material region including a color material, a yellow region 81 including a yellow dye as a color material, a magenta region 82 including a magenta dye as a color material, and a cyan dye are used. A cyan region 83 including a color material and a black region 84 including a black color material are provided. As shown in FIGS. 12 and 13, a yellow region 81, a magenta region 82, a cyan region 83, a black region 84, a diffractive optical variable element region 85, and a cover layer region 86 are repeatedly arranged on the base sheet 89. Has been. However, the color material region included in the thermal transfer sheet 80 can be changed as appropriate in accordance with the display elements of the personal information display body 10 to be manufactured.

  By the way, as shown in FIG. 13, in the diffractive optical variable element region 85 of the illustrated thermal transfer sheet 80, the release layer 85a, the concavo-convex formation layer 85b, the reflection layer 85c, and the heat seal layer 85d are sequentially arranged from the base sheet 89 side. Are stacked on the base sheet 89. In this thermal transfer sheet 80, the thermal head 62 contacts the base sheet 89 and presses the heat seal layer 85 d against the display body 20. Then, the heat seal layer 85d forms the bonding layer 56 of the personal information display body 10 shown in FIG. The reflective layer 85c of the thermal transfer sheet 80 forms the reflective layer 54 of the personal information display body 10 shown in FIG. 10, and the concave / convex forming layer 85b of the thermal transfer sheet 80 becomes the personal information display shown in FIG. The unevenness forming layer 52 of the body 10 is formed. That is, in the illustrated thermal transfer sheet 80, the reflective layer 85 c and the unevenness forming layer 85 b form a diffractive optical variable element layer including the diffractive optical variable element 50 that forms the first display element 41. Moreover, the peeling layer 85a is a layer which has peelability with respect to the adjacent uneven | corrugated formation layer 85b.

  As described above, the diffractive optical variable element 50 can be formed from various elements whose manner of observation, for example, brightness, color, etc., changes depending on the observation direction by using the diffraction phenomenon. For this reason, the configuration of the diffractive optical variable element region 85 of the thermal transfer sheet 80, in particular, the concavo-convex forming layer 85b and the reflective layer 85c of the diffractive optical variable element region 85 of the diffractive optical variable element 50 to be transferred onto the display body 20 is provided. It can change suitably according to a structure. For example, the diffractive optical variable element region 85 of the thermal transfer sheet 80 may include a transmissive hologram or diffraction grating, or may include a volume hologram or diffraction grating.

  As shown in FIG. 13, in the illustrated cover layer region 86 of the thermal transfer sheet 80, a release layer 86a, a protective layer 86b, an ultraviolet absorbing layer 86c, and a heat seal layer 86d are sequentially formed from the base sheet 89 side. It is overlaid on the base material sheet 89. The cover layer region 86 comes into contact with the display body 20 from the heat seal layer 86 d side when the thermal head 62 contacts the base sheet 89. When the cover layer 34 of the personal information display body 10 shown in FIG. 10 is formed using the thermal transfer sheet 80, the cover layer 34 includes a heat seal layer 86d, an ultraviolet absorbing layer 86c, and a protective layer 86b. The protective layer 86b is a layer that forms the outermost surface of the personal information display body 10, and preferably has transparency, scratch resistance, and the like. The ultraviolet absorbing layer 86c is a layer located inside the protective layer 86b, that is, on the diffractive optical variable element 50 side in the personal information display body 10, and absorbs ultraviolet rays. Thereby, it can prevent effectively that the display elements 41, 42, and 43 of the personal information display body 10 located inside the ultraviolet absorption layer 86c are deteriorated by ultraviolet rays. The ultraviolet absorbing layer 86c can be omitted as necessary.

  In addition, the personal information display manufacturing apparatus 60 of the present embodiment includes a recording unit 65 that records personal information of a specific person. Specifically, the recording unit 65 records an image of a specific person corresponding to the personal information displayed by the first display element 41 and the second display element 42 as an image, or the personal information displayed by the third display element 43. Is recorded as symbol information such as letters and numbers, and the name, gender, and date of birth corresponding to the personal information displayed by the fourth display element 44 are recorded as character information. In the example shown in FIG. 1, the first display element 41 and the second display element 42 display the upper body including the face based on the same image recorded in the recording means 65. According to such a recording unit 65, the first display element 41 and the second display element 42 can be produced based on one piece of personal information recorded in the recording unit 65.

  Using the thermal transfer device 61 and the thermal transfer sheet 80 of the manufacturing apparatus 60 as described above, the display elements 41, 42, 43, 44 and the cover layer 34 are formed on the display body 20 as follows.

  First, the display body 20 to be processed next is supplied onto the support means 63. The thermal transfer sheet 80 is supplied between the thermal head 62 and the support means 63 by the thermal transfer sheet supply means 64 in accordance with the supply of the display body 20. The thermal transfer sheet 80 is positioned so that the yellow area 81 faces the display body 20 on the support means 63. In this state, based on the personal information recorded in the recording means 65, the thermal head 62 sublimates and transfers the yellow dye in the yellow region 81 to the display body 20 in an arrangement pattern capable of displaying the personal information. . Next, in a state where the display body 20 is held on the support means 63, the thermal transfer sheet 80 is conveyed, and the magenta area 82 located next to the yellow area 81 where the thermal transfer process is completed faces the display body 20. become. In this state, the thermal head 62 performs sublimation thermal transfer of the magenta dye in the magenta region 82 to the display body 20 in an arrangement pattern capable of displaying the personal information based on the personal information recorded in the recording unit 65. . In the same process, the cyan dye and the black color material in the cyan region 83 are thermally transferred to the display body 20 in a pattern capable of displaying personal information. As described above, the color layer 36 and the black layer 37 are formed on the display body 20.

  Thereafter, the thermal transfer sheet 80 is conveyed, and the diffractive optical variable element region 85 of the thermal transfer sheet 80 faces the display body 20 on the support means 63. In this state, the diffractive optical variable element 50 is arranged with a gradation of binary or higher for each of the plurality of unit regions 48 virtually defined on the display body 20. For example, in the binary gradation, the thermal head 62 corresponds to the thermal transfer sheet 80 so that the diffractive optical variable element region 85 of the thermal transfer sheet 80 contacts the predetermined unit region 48 among the many unit regions 48. Push in the heating position. Due to the heating from the thermal head 62, the heat seal layer 85d of the diffractive optical variable element region 85 has adhesiveness at a position where it abuts on the display body 20. For this reason, the unevenness forming layer 85b is peeled off from the release layer 85a having releasability, and the reflective layer 85c and the unevenness forming layer 85b are removed from the base sheet 89 of the thermal transfer sheet 80 via the heat seal layer 85d. Transcribed above. In this way, the diffractive optical variable element 50 including the reflective layer 85c and the unevenness forming layer 85b is thermally transferred onto the display body 20. Finally, based on the personal information recorded in the recording means 65, the diffractive optics is variable on the display body 20 in an arrangement pattern capable of displaying the personal information of the specific person to whom the personal information display body 10 is to be given. An element 50 is provided. As described above, the first display element 41 including the diffractive optical variable element 50 is formed on the display body 20.

  Next, the thermal transfer sheet 80 is conveyed, and the cover layer region 86 of the thermal transfer sheet 80 faces the display body 20 on the support means 63. The cover layer region 86 is transferred to the entire area on the display body 20 by heat and pressure from the thermal head 62. Accordingly, the first to fourth display elements 41 to 44 provided in the display body 20 are covered with the cover layer 34 including the ultraviolet absorbing layer 86c and the protective layer 86b joined through the heat seal layer 86d. Become.

  As described above, according to the manufacturing method and the manufacturing apparatus of the present embodiment, the personal information of a specific person, for example, the owner is displayed by the arrangement pattern of the diffractive optical variable element 50 that requires advanced manufacturing technology. The personal information display 10 including the display element 41 can be manufactured relatively easily. According to the personal information display 10 manufactured in this way, the first display element 41 is formed using the diffractive optical variable element 50, which makes it difficult to forge the personal information display 10. it can. On the other hand, personal information only needs to be displayed in the arrangement pattern of the diffractive optical variable element 50, so that there is no need to record the personal information on the diffractive optical variable element 50 itself, for example, as an uneven structure or interference fringes. Therefore, according to the manufacturing method and manufacturing apparatus of the present embodiment, the personal information display 10 having excellent anti-counterfeiting properties can be manufactured relatively easily.

  Further, according to the manufacturing method and the manufacturing apparatus of the present embodiment, as described above, the thermal transfer sheet 80 is heated and pressurized using the thermal head 62, whereby the diffractive optics can be varied in an arrangement pattern that can display personal information. The element 50 is thermally transferred to the display body 20. In this case, the diffractive optical variable element 50 can be thermally transferred to each display body 20 in different arrangement patterns that can display desired personal information.

  Furthermore, in the manufacturing method and manufacturing apparatus of the present embodiment, one thermal transfer sheet 80 is used for the first display element 41, the second display element 42, the third display element 43, and the fourth display of one personal information display body 10. The diffractive optical variable element region 85 and the color material regions 81 to 84 for forming the element 44 and the cover layer 34 are all included. Therefore, the first display element 41, the second display element 42, the third display element 43, and the fourth display element 44 can be accurately positioned with respect to each other.

  In addition, according to the personal information display body 10 of FIG. 1 manufactured by the manufacturing method and manufacturing apparatus according to the present embodiment, the first display element 41 displays an image of a specific person by the arrangement pattern of the diffractive optical variable element 50. indicate. In general, in order to authenticate the owner of the personal information display body 10 based on the personal information display body 10, it is preferable that an image of the owner, particularly a face, is displayed on the personal information display body 10. When the image of the owner, in particular, the face is recorded on the personal information display body 10, the authentication of the owner and the authentication of the personal information display body 10 based on the authentication result can be easily and accurately performed. it can. In addition, the first display element 41 displays the image of the owner, particularly the face, according to the arrangement pattern of the diffractive optical variable element 50 that requires advanced manufacturing technology. Therefore, according to the personal information display 10 of FIG. 1, the personal information display 10 that can be manufactured relatively easily can be provided with extremely excellent anti-counterfeiting properties, and the personal information display 10 10 can be used to authenticate the owner and to determine the authenticity of the personal information display 10 very easily and accurately.

  However, the above manufacturing method is merely an example, and various modifications can be made. For example, in the manufacturing method described above, the first display element 41, the second display element 42, the third display element 43, the fourth display element 44, and the cover layer 34 are formed on the display body 20 by thermal transfer. An example is shown, but the present invention is not limited to this. The first display element 41, the second display element 42, the third display element 43, and the fourth display element 44 are formed by thermal transfer on the cover layer 34 that is supplied so as to face the thermal head 62. Even when the cover layer 34 on which the first display element 41, the second display element 42, the third display element 43, and the fourth display element 44 are formed is laminated on the display body main body 20, the personal information display body 10 is produced. Good. In this case, as shown in FIG. 19, the yellow region 81, the magenta region 82, the cyan region 83, the black region 84, and the diffractive optical variable element region 85 are repeatedly arranged on the base sheet 89 of the thermal transfer sheet 80. The In the diffractive optical variable element region 85, the peeling layer 85 a, the reflective layer 85 c, the unevenness forming layer 85 b, and the heat seal layer 85 d are stacked on the base sheet 89 in order from the base sheet 89 side.

  Although not particularly mentioned in the above manufacturing method, the receiving layer 28b that can receive the dye may be thermally transferred onto the display body 20 prior to the sublimation thermal transfer of the coloring material containing the dye. In this case, the thermal transfer sheet 80 may have an area including the receiving layer between the cover layer area 86 and the yellow area 81.

  Furthermore, each region included in the thermal transfer sheet 80 can be appropriately changed according to the configuration of the display element to be formed on the display body 20. As an example, in the personal information display body 10 shown in FIGS. 2 and 3, a second display element 421 using a fluorescent material is provided on the display body 20. Therefore, as shown in FIG. 14, if the thermal transfer sheet 80 further includes a fluorescent light emitting material region 88 containing a fluorescent light emitting material, the second information of the personal information display body 10 shown in FIG. 2 and FIG. The display element 421 can be formed on the display body 20 by thermal transfer. In the thermal transfer sheet 80 shown in FIG. 14, the diffractive optical variable element region 85 for forming the first display element 411 and the fluorescent light emitting material region 88 for forming the second display element 421 are the same base. Since they are arranged side by side on the material sheet 89, the first display element 411 and the second display element 421 can be aligned with respect to each other with high accuracy. Thereby, the personal information display body 10 including the first display element 411 and the second display element 421 that display the same image at the same position can be manufactured relatively easily without difficulty.

  Further, a thermal transfer sheet for forming the color layer 36 on the display body 20 and a thermal transfer sheet for forming the diffractive optical variable element 50 and the cover layer 34 on the display body 20 are prepared separately. May be. FIG. 16 shows a first thermal transfer sheet 80a in which a yellow region 81, a magenta region 82, a cyan region 83, and a black region 84 are repeatedly formed in order on a base sheet 89. Such a first thermal transfer sheet 80a is widely used in normal sublimation thermal transfer printing without being limited to application to the personal information display 10, and is available at low cost. On the other hand, FIG. 17 shows a second thermal transfer sheet 80 b in which a diffractive optical variable element region 85 and a cover layer region 86 are repeatedly formed in order on a base sheet 89.

  FIG. 15 shows a method and apparatus for manufacturing the personal information display 10 using the first thermal transfer sheet 80a shown in FIG. 16 and the second thermal transfer sheet 80b shown in FIG. In the manufacturing method and the manufacturing apparatus shown in FIG. 15, the personal information display body manufacturing apparatus 60 is arranged downstream of the thermal transfer apparatus 61 along the transport direction of the display body 20 in addition to the thermal transfer apparatus 61 described above. A second thermal transfer device 66 is further provided. The second thermal transfer device 66 can be composed of a thermal transfer printer similar to the thermal transfer device 61. The thermal transfer sheet supply means 64 of the thermal transfer device 61 supplies the first thermal transfer sheet 80a. Therefore, the thermal transfer device 61 forms the color layer 36 and the black layer 37 on the display body 20.

  On the other hand, the second thermal transfer device 66 includes a second thermal transfer sheet supply unit 69 that supplies the second thermal transfer sheet 80b, and a second support unit 68 that supports the display body 20 on which the color layer 36 and the black layer 37 are formed. And a second thermal head 67 that heats and presses the second thermal transfer sheet 80b toward the display body 20 on the second support means 68. The second thermal transfer sheet supply means 69 has a feed roll 69a for feeding out the second thermal transfer sheet 80b and a recovery roll 69b for collecting the second thermal transfer sheet 80b after the thermal transfer. The second thermal transfer sheet 80b fed from the feed roll 69a passes between the second thermal head 67 and the second support means 68 and is collected by the collection roll 69b.

  In the illustrated example, the display body 20 is supplied to the first thermal transfer device 61 one by one from a display body supply means (not shown). Then, in the first thermal transfer device 61, the color layer 36 and the black layer 37 are thermally transferred to the display body 20. The display body 20 on which the color layer 36 and the black layer 37 are formed is then transported to the second thermal transfer device 66, where the diffractive optical variable element 50 and the cover layer 34 are placed on the display body 20. Thermally transferred.

  Further, in the personal information display 10 shown in FIGS. 1 to 3, the area where the diffractive optical variable element 50 is transferred on the display body 20 is small. Therefore, as shown in FIG. 18 as an example, the size of the diffractive optical variable element region 85 in the thermal transfer sheet 80 and the second thermal transfer sheet 80b is small considering the size of the diffractive optical variable element 50 to be transferred. May be used. In this case, the cost of the thermal transfer sheet 80 and the second thermal transfer sheet 80b can be effectively reduced. In connection with this, the manufacturing cost of the personal information display body 10 can be reduced effectively.

  In addition, according to the manufacturing method and manufacturing apparatus of the personal information display 10 according to the present embodiment described above, for example, as shown in FIGS. 20 and 21 in addition to the personal information display 10 shown in FIGS. The personal information display 10 to be manufactured can also be manufactured. 20 and 21 are views corresponding to FIG. 1 and are plan views showing still other examples of the personal information display body.

  The personal information display body 10 shown in FIG. 20 has first to fourth and sixth display elements 412, 422, 43, 44, 46. Among these, the second to fourth display elements 422, 43 and 44 of the personal information display body 10 shown in FIG. 20 are the second to fourth display elements of the personal information display body 10 shown in FIG. 1, respectively. 42 to 44 may be configured identically.

It can be configured identically.

  The first display element 413 displays the personal information as a negative depending on the arrangement pattern of the diffractive optical variable element 50. Here, “displaying personal information in a negative manner according to the arrangement pattern of the diffractive optical variable element 50” means displaying the information in reverse, in other words, adjacent to the region where the diffractive optical variable element 50 is disposed. It represents a symbol or image indicating personal information in an area. According to such a form, even if the region where the diffractive optical variable element 50 is disposed does not represent personal information, by expressing a symbol or image indicating personal information in a region adjacent to the region, The first display element 413 can display personal information. The first display element 413 shown in FIG. 21 displays the background of the image of the specific person displayed by the second display element 423.

  In addition, as shown in FIG. 21, at least a part of the outer contour of the arrangement pattern of the first display element 413 extends along at least a part of the outer contour of the second display element 423. In other words, at least a part of the outline of the first display element 413 and at least a part of the outline of the second display element 423 have complementary shapes that are related to each other. Since the first display element 413 and the second display element 423 manufactured by different methods extend at least partially along the outer contour of each other, it is difficult to effectively counterfeit the personal information display body 10. can do. In particular, in the personal information display 10 shown in FIG. 21, the first display element 413 is displayed by the first display element 413 in addition to exhibiting excellent anti-counterfeiting properties alone as described above. The personal information and the personal information displayed by the second display element 423 are observed in association with each other. For this reason, forgery of the personal information display body 10 can be made extremely difficult.

  As mentioned above, although this invention was demonstrated based on embodiment shown in figure, this invention is not limited to these embodiment, In addition, it can implement in a various aspect.
