Description

  The present invention relates to a card manufacturing method and a card in which information is recorded so as to be recognizable from the outside.

  2. Description of the Related Art In recent years, with the development of an information-oriented society, predetermined information is recorded on a card, and a service for performing personal authentication, a service for enabling shopping, and the like are performed using the card on which the information is recorded. In such a service, information determined according to its use is recorded in advance on a predetermined card, and when using the service, the information recorded on the card is read, and the read information is used for the service. Is provided.

  There are various types of cards on which such information can be recorded, but ICs are embedded as structurally complex from the one with the simplest structure that displays information on the surface. IC card etc. In these cards, the recorded information is read by a reading method corresponding to the information recording method for the card. For example, in a card with barcode information displayed on the surface, information recorded as a barcode is read by flicking a barcode reader on the surface, and in a card with a magnetic stripe attached on the surface, Information recorded on the magnetic stripe is read by a dedicated reading device that reads information by magnetism, and further, in a card embedded with an IC, the information is recorded on the IC by a dedicated reading device that electrically reads information from the IC. Information is read.

  As described above, the card having the barcode information displayed on the front surface and the card having the identification information such as numerals and alphabets displayed on the front surface, in addition to the information printed on the card base material, a laser beam Some of these information is recorded so that they can be recognized from the outside. In the case where information is recorded using laser light, it is possible to prevent the information from being erased due to rubbing or the like, as compared with the case where information is printed.

  When recording information on a card using laser light, for example, a YAG laser is irradiated on the card, and a pattern such as characters can be formed by sublimating only the printed layer laminated on the lower part of the transparent film layer. (For example, refer to Patent Document 1). Since the YAG laser has a characteristic of transmitting a transparent material, it is possible to sublimate only the printed layer laminated below the transparent film layer without sublimating the transparent film layer. However, when only the printed layer laminated on the lower part of the transparent film layer is sublimated in this way, the film layer does not sublime, so the gas generated by sublimation of the printed layer accumulates at the lower part of the film layer, It swells up.

Therefore, it is considered to display information on the card by irradiating the card with a CO ₂ laser and sublimating a transparent film layer laminated on the upper surface together with the printed layer. In this way, when the card is irradiated with the CO ₂ laser, the transparent film layer is sublimated together with the print layer, so that the gas generated by sublimation of the print layer is not accumulated below the film layer.
JP 2002-352932 A

As described above, when a card is irradiated with a CO ₂ laser and a transparent film layer is sublimated together with the print layer to display information on the card, the print layer and the film layer are sublimated simultaneously. It is necessary to increase the output of the laser or to reduce the speed of scanning the surface with the laser beam. However, when the output of the laser beam is increased, the cost of the apparatus increases and the speed of scanning the surface with the laser beam is decreased. In this case, there is a problem that productivity is lowered.

  In addition, in order to sublimate the substrate by irradiating the laser beam, it is necessary to focus the laser beam on the surface of the substrate, so that the focus is adjusted to either the film layer or the printing layer. However, there is a problem in that the processing quality of the layer that is out of focus is deteriorated.

  In addition, it is difficult to adjust the output of the laser beam for sublimating the print layer and the film layer at the same time. If the output of the laser beam is increased too much, the print layer may be burnt, and if the output of the laser beam is decreased too much, If the edge is not processed cleanly and the displayed information requires high definition for reading, for example, barcode information, there is a problem that the quality of the product is degraded.

  The present invention has been made in view of the problems of the conventional techniques as described above, and improves the quality of information display without increasing the apparatus cost or reducing the productivity. An object of the present invention is to provide a card manufacturing method and a card that can be used.

In order to achieve the above object, the present invention provides:
A printed layer is formed on at least a part of the first layer made of an opaque material, and a second layer made of a transparent material is laminated on the surface of the first layer on which the printed layer is formed, The printed layer and the second layer are a method for manufacturing a card on which the information is displayed by removing the printed layer and the second layer in a pattern according to the shape of the information to be displayed,
The second layer is irradiated with a pattern corresponding to the shape of the information with a CO ₂ laser focused on the second layer with respect to a region of the _second layer facing the print layer. Sublimating with a pattern according to the shape of the information,

In the present invention configured as described above, first, the second layer is sublimated in a pattern according to the shape of the information to be displayed by irradiating the second layer with a focus on the CO ₂ laser, Thereafter, the printed layer is sublimated in a pattern corresponding to the shape of information to be displayed by irradiating the region where the second layer is sublimated with a CO ₂ laser focused on the printed layer. In this way, the pattern corresponding to the shape of the information to be displayed is obtained by irradiating the second layer and the printing layer with the CO ₂ laser focusing on the second layer and the printing layer in separate steps. Therefore, processing suitable for each of the second layer for displaying information and the printed layer is performed, and the quality of information display is improved.

  As information to be displayed, barcode information can be considered. Barcode information requires fineness for reading, but because the quality of information display is improved by the above-described process, even if fineness is required for reading barcode information or the like, Can be read reliably.

In the card in which the first layer made of an opaque material and the second layer made of a transparent material are laminated,

  In the present invention configured as described above, although an information storage unit capable of writing and / or reading information is provided, the second layer and the printing layer have patterns corresponding to the shape of information to be displayed. Since the information is displayed by being removed in step (b), the information can be displayed without being limited by the shape or arrangement area of the information storage unit and without being erased by rubbing or the like.

As described above, in the present invention, information to be displayed by irradiating the second layer and the printed layer with the CO ₂ laser focused on the second layer and the printed layer in separate steps, respectively. Since it is configured to be removed with a pattern according to the shape of the material, processing suitable for each of the second layer for displaying information and the printing layer is performed, which increases the apparatus cost and decreases the productivity. Therefore, the quality of information display can be improved.

  In addition, when an information storage unit capable of writing and / or reading information is provided, the information is displayed by removing the second layer and the printing layer in a pattern corresponding to the shape of the information to be displayed. By adopting such a configuration, the information can be displayed without being limited by the shape and arrangement area of the information storage unit and without being erased by rubbing or the like.

  Embodiments of the present invention will be described below with reference to the drawings.

  1A and 1B are diagrams showing an embodiment of a card manufactured by the card manufacturing method of the present invention. FIG. 1A is an external surface view, and FIG. 1B is an AA ′ cross section shown in FIG. FIG.

  In this embodiment, as shown in FIG. 1, a printing layer 30 is formed on a part of the back sheet 20 which is a first layer made of opaque white PET by silk printing, and the printing layer 30 of the back sheet 20 is formed. A top sheet 10 as a second layer made of transparent PET is laminated on the entire surface. A part of the surface sheet 10 and the printing layer 30 is sublimated and removed by irradiating the laser beam, whereby the identification information 31 to be displayed information and the barcode information 32 representing the identification information 32 as a barcode. The identification information 31 and the barcode information 32 are displayed so as to be recognizable from the surface. In addition, in the surface sheet 10, not only what consists of PET but if it is transparent, you may select appropriate materials, such as what consists of PET-G. Similarly, the back sheet 20 is not limited to a material made of PET, and an appropriate material such as a material made of PET-G may be selected as long as it is opaque.

  In the card 1 configured as described above, the identification information 31 displayed so as to be identifiable from the front surface is visually recognized, or the barcode information 32 is read by flicking a barcode reader. Authentication using can be performed.

  Below, the manufacturing method of the card | curd 1 mentioned above is demonstrated.

  FIG. 2 is a diagram for explaining a method of manufacturing the card 1 shown in FIG. 3 is a diagram showing a detailed shape of the processed part in the step shown in FIG. 2, and (a) is a diagram showing a detailed shape of the processed part in the step shown in FIG. FIG. 3B is a diagram showing a detailed shape of a processed part in the step shown in FIG.

  First, the printing layer 30 is formed with black ink by silk printing in a predetermined region on one surface of the back sheet 20 made of opaque white PET (FIG. 2A).

  Next, the top sheet 10 made of transparent PET is laminated on the entire surface of the back sheet 20 on which the printed layer 30 is formed, and the top sheet 10 and the back sheet 20 are bonded to each other with an adhesive (not shown) ( FIG. 2 (b)).

Next, the region facing the printing layer 30 in the top sheet 10 is irradiated with a CO ₂ laser in a pattern corresponding to the shapes of the identification information 31 and the barcode information 32. At this time, the CO ₂ laser irradiates the top sheet 10 with a focus. Thereby, only the top sheet 10 is sublimated in a pattern corresponding to the shapes of the identification information 31 and the barcode information 32 and removed (FIG. 2C). At this time, in the surface sheet 10, as shown in FIG. 3A, the edge portion of the sublimation caused by the irradiation of the CO ₂ laser has an inclination.

Thereafter, the CO ₂ laser is irradiated with a pattern corresponding to the shapes of the identification information 31 and the barcode information 32 while focusing on the printing layer 30. Since the surface sheet 10 has already been sublimated in a pattern corresponding to the shape of the identification information 31 and the barcode information 32 by the above-described process, the surface area 10 is irradiated with the CO ₂ laser. It will be. As a result, the print layer 20 is sublimated in a pattern corresponding to the shapes of the identification information 31 and the barcode information 32 and removed (FIG. 2D). At this time, since only the print layer 30 focused on the print layer 30 is sublimated, the output adjustment of the laser beam is facilitated, and the print layer 30 is not burnt. Moreover, since the thickness of the inclined portion of the topsheet 10 shown in FIG. 3A is thin, as shown in FIG. 3B, it is sublimated together with the printing layer 20 to be removed. The edge portions of the identification information 31 and the barcode information 32 become clean, and the quality of information display of the card 1 is improved.

  Through the series of steps described above, the top sheet 10 and the printing layer 30 are removed in a pattern according to the shape of the identification information 31 and the barcode information 32, and the black color of the printing layer 30 is used as the background, and the back sheet 20 is displayed in white. Thus, the identification information 31 and the barcode information 32 can be recognized from the front surface, and the card 1 with improved quality of display of the identification information 31 and the barcode information 32 is manufactured. In particular, even barcode information 32 that requires high definition can be reliably read by improving the quality of information display as described above. The colors of the back sheet 20 and the printing layer 30 are not limited to the above-described white and black, but may be different from each other as long as the identification information 31 and the barcode information 32 can be recognized.

  Here, the productivity of the card 1 in the manufacturing method of the card 1 described above will be described in detail.

In the card 1 manufacturing method described above, the surface sheet 10 is sublimated in a pattern corresponding to the shape of the identification information 31 and the barcode information 32, and the printing layer 30 is matched to the shape of the identification information 31 and the barcode information 32. The sublimation process is performed in a separate process. Therefore, in each of the processes, a process for sublimating one layer with a pattern according to the shape of the identification information 31 and the barcode information 32 may be performed. Therefore, the speed at which the surface of the card 1 is scanned by the CO ₂ laser. Can be made faster than when the topsheet 10 and the printing layer 30 are sublimated simultaneously. For example, when sublimating the top sheet 10 and the printing layer 30 simultaneously, the scanning speed is 1000 mm / sec, whereas one layer is sublimated with a pattern according to the shape of the identification information 31 and the barcode information 32. In this case, the scanning speed can be 2500 mm / sec.

  Accordingly, the formation speed of the identification information 31 and the barcode information 32 can be improved. For example, when sublimating the top sheet 10 and the printing layer 30 simultaneously, 1358 mS is required to form the identification information 31 and the barcode information 32, whereas the identification information 31 and the barcode information 32 are used for one layer. In the case of sublimation with a pattern corresponding to the shape of the image, 542 nS per layer is required to form the identification information 31 and the barcode information 32, and 542 mS × 2 = 1084 mS is sufficient.

  Thus, in this embodiment, productivity can be improved compared with the case where the surface sheet 10 and the printing layer 30 are sublimated simultaneously.

  In the present embodiment, the print layer 30 is formed on a part of the back sheet 20, but the print layer 30 may be formed on the entire surface of the back sheet 20 to be bonded to the top sheet 10.

(Other embodiments)
4A and 4B are diagrams showing another embodiment of a card manufactured by the card manufacturing method of the present invention. FIG. 4A is an external surface view, FIG. 4B is a diagram showing an internal structure, and FIG. It is AA 'sectional drawing shown to (a), (b).

  In the present embodiment, as shown in FIG. 4, an inlet 140 is laminated on a back sheet 120, which is a first layer made of opaque white PET, and silk printing is performed on the entire surface of the inlet 140 opposite to the back sheet 120. Thus, the print layer 130 is formed, and the top sheet 110 as the second layer made of transparent PET is laminated on the entire surface of the inlet 140 on which the print layer 130 is formed. The surface sheet 110 and the printing layer 130 are partially sublimated and removed by irradiation with laser light, whereby the identification information 131 as information to be displayed and the barcode information 132 representing the identification information 132 as a barcode. The identification information 131 and the barcode information 132 are displayed so as to be recognizable from the surface. In addition, in the surface sheet 110, you may select appropriate materials, such as not only what consists of PET but what consists of PET-G if it is transparent. Similarly, the back sheet 120 is not limited to a material made of PET, and an appropriate material such as a material made of PET-G may be selected as long as it is opaque. In addition, the inlet 140 is configured by forming a coiled antenna 142 on a resin sheet 143 and connecting an IC chip 141 to both ends of the coiled antenna 142. The identification information 131 and the barcode information 132 are displayed in a region facing a part of the antenna 142.

  In the non-contact type IC card 101 configured as described above, the identification information 131 displayed so as to be identifiable from the front surface is visually recognized, or the barcode information 132 is read by turning the barcode reader. Thus, authentication using the non-contact type IC card 101 can be performed. Also, by bringing the information writing / reading device provided outside close to the antenna 142, a current flows to the antenna 142 by electromagnetic induction from the information writing / reading device, and this current is supplied from the antenna 142 to the IC chip 141. Thereby, in a non-contact state, information is written from the information writing / reading device to the IC chip 141 via the antenna 142, or information written to the IC chip 141 is sent via the antenna 142 to the information writing / reading device. Or read out. That is, the IC chip 141 and the antenna 142 serve as an information storage unit in the present invention. The information storage unit may have a function of only writing information or reading information.

  Below, the manufacturing method of the non-contact type IC card 101 mentioned above is demonstrated.

  FIG. 5 is a diagram for explaining a method of manufacturing the non-contact type IC card 101 shown in FIG.

  First, an inlet 140 in which an antenna 142 is formed on a resin sheet 143 on one surface of a back sheet 120 made of opaque white PET and an IC chip 141 is mounted so as to be connected to the antenna 142. Are bonded together with an adhesive (not shown) (FIG. 5A).

  Next, a printing layer 130 is formed with black ink by silk printing on the entire surface of the inlet 140 bonded to the back sheet 120 on the side opposite to the back sheet 120 (FIG. 5B).

  Next, a surface sheet 110 made of transparent PET is laminated on the entire surface of the inlet 140 on which the printing layer 130 is formed, and the surface sheet 110 and the inlet 140 are bonded with an adhesive (not shown) (FIG. 5). (C)).

Next, the surface sheet 110 is irradiated with a CO ₂ laser in a pattern corresponding to the shapes of the identification information 131 and the barcode information 132. At this time, the CO ₂ laser irradiates the top sheet 110 with a focus. As a result, only the top sheet 110 is sublimated in a pattern according to the shape of the identification information 131 and the barcode information 132 and removed (FIG. 5D). At this time, in the surface sheet 110, the edge portion of the sublimation by the irradiation of the CO ₂ laser has an inclination.

Thereafter, the CO ₂ laser is irradiated with a pattern corresponding to the shapes of the identification information 131 and the barcode information 132 while focusing on the printing layer 130. Since the surface sheet 110 has already been sublimated in a pattern corresponding to the shape of the identification information 131 and the barcode information 132 by the above-described steps, the CO ₂ laser is irradiated to the area where the surface sheet 110 is sublimated. It will be. Thereby, the print layer 120 is sublimated in a pattern corresponding to the shapes of the identification information 131 and the barcode information 132 and removed (FIG. 5E). At this time, since only the print layer 130 focused on the print layer 130 is sublimated, the output adjustment of the laser light becomes easy, and the print layer 130 is not burnt. In addition, the inclined portion of the surface sheet 110 generated by sublimation of the surface sheet 110 is thinned and removed by sublimation together with the printing layer 120, thereby the identification information 131 and the barcode information 132. The edge portion becomes clean, and the quality of information display of the non-contact type IC card 101 is improved.

  Through the series of steps described above, the top sheet 110 and the print layer 130 are removed in a pattern corresponding to the shapes of the identification information 131 and the barcode information 132, and the resin sheet 143 constituting the inlet 140 with the black color of the print layer 130 as the background Is transparent, the back sheet 120 is displayed in white, and when the resin sheet 143 is opaque, the identification information 131 and barcode information 132 displayed in the color of the resin sheet 143 can be recognized from the front surface. The non-contact type IC card 101 with improved quality for displaying the identification information 131 and the barcode information 132 is manufactured. In particular, even barcode information 132 that requires high definition can be reliably read by improving the quality of information display as described above.

  Further, although the identification information 131 and the barcode information 132 overlap with a part of the antenna 142, the top sheet 110 and the printed layer 130 are removed in a pattern corresponding to the shape of the identification information 131 and the barcode information 132. Therefore, the area where the identification information 131 and the barcode information 132 are displayed is limited by the shape and the arrangement area of the IC chip 141 and the antenna 142 as in the case of displaying the information by embossing or the like. In addition, it is possible to prevent the identification information 131 and the barcode information 132 from being erased due to rubbing or the like, as in the case where information is printed on the surface.

  In this embodiment, the case where the identification information 131 and the barcode information 132 overlap with part of the antenna 142 has been described as an example. However, the identification information 131 and the barcode information 132 overlap with the IC chip 141. May be.

  In this embodiment, the print layer 130 is formed on the entire surface of the inlet 140. However, the print layer 130 may be formed only in a region where the identification information 131 and the barcode information 132 of the inlet 140 are displayed.

  In this embodiment, the non-contact type IC card 101 having an inlet 140 formed with an IC chip 141 mounted on the resin sheet 143 so as to be connected to the antenna 142 is taken as an example. As described above, the present invention can also be applied to a magnetic card in which a magnetic stripe is formed on the back sheet 120 and laminated with the top sheet 110.
