Japanese Utility Model Publication No. 64-13376 Japanese Patent Laid-Open No. 2004-9657

 However, in the conventional barcode forming method for the end face of the information card, the barcode is formed from one side of the information card to the other side (that is, over almost the entire length in the thickness direction of the information card). When reading a barcode with a reading device with two or more cards stacked, the reading device is not in contact with the end face of the information card substantially in parallel, but is in contact with the end face of the information card at an angle. There is a problem that the barcodes of a plurality of information cards are read over the information cards, and the barcodes of each information card cannot be read accurately. That is, it is difficult to individually manage information cards having barcodes formed by a conventional method in a state where a large number of information cards are stacked.

 The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an information card that can individually read a barcode formed on an end face in a stacked state, and a manufacturing method thereof.

 The information card of the present invention is an information card comprising a core substrate and a surface substrate laminated on both surfaces of the core substrate, wherein the core substrate is made of polyvinyl chloride, and the surface substrate The material is made of a base material different from the core base material, and a machine reading code is formed on at least one end surface of the core base material.

 The information card manufacturing method of the present invention includes a core base material and a surface base material laminated on both sides of the core base material, the core base material is made of polyvinyl chloride, and the surface base material is A method of manufacturing an information card comprising a base material made of a material different from a core base material and having a machine reading code formed on at least one end surface of the core base material, wherein a laser beam is applied to at least one end surface of the core base material. Irradiating and forming a machine reading code on at least one end surface of the core substrate; and a process B of laminating the surface substrate on both surfaces of the core substrate. The method of manufacturing an information card, wherein the steps B are in random order.

According to the information card of the present invention, the machine reading code is formed only on the core base material, and the surface base material is laminated on both surfaces of the core base material. Even when the reading code is read, it is possible to prevent the machine reading code from being read as one machine reading code across two or more information cards (collecting the machine reading codes of two or more information cards).
That is, when trying to read the machine reading code provided on the end face of the information card of the present invention, it is possible to read the code when the reading device comes into contact with the end face almost in parallel. When the device is in contact with the end surface at an angle, the reading device straddles two or more information cards, and a surface base material is interposed between the machine reading codes, so that a reading error (miss) is caused. Since it can be recognized, it is possible to prevent two or more machine reading codes from being erroneously read as one code.

 According to the method for manufacturing an information card of the present invention, a base material made of polyvinyl chloride is used as a core base material, and a base material different from the core base material is used as a surface base material. Since the laser beam is irradiated, the machine reading code can be formed only on the core base material. Further, even if the laser beam hits the end surface of the surface base material, the surface base material is not discolored, so that a machine reading code is not mistakenly formed on the end surface of the surface base material.

It is the schematic which shows one Embodiment of the information card | curd of this invention, (a) is a top view, (b) is a side view. It is a schematic sectional drawing which shows the management method of the information card | curd of this invention.

Embodiments of the information card and the manufacturing method thereof according to the present invention will be described.
Note that this embodiment is specifically described in order to better understand the gist of the invention, and does not limit the present invention unless otherwise specified.

"Information Card"
FIG. 1 is a schematic view showing an embodiment of an information card of the present invention, where (a) is a plan view and (b) is a side view.
The information card 10 of the present embodiment is schematically configured from a core base material 11 and surface base materials 12 and 13 laminated on both surfaces (one surface 11a and the other surface 11b) of the core base material 11.
That is, the surface base material 12 is provided so as to cover one surface 11 a of the core base material 11, and the surface base material 13 is provided so as to cover the other surface 11 b of the core base material 11. Yes.

On one end surface (side surface) 11c of the core base material 11, a machine reading code 14 is formed which is formed by irradiating the end surface 11c with laser light.
Examples of the machine reading code 14 include a bar code and a list of fine characters. When the machine reading code 14 is a bar code, for example, the bar is formed along the thickness direction of the core substrate 11.

As the core substrate 11, a substrate made of a material that changes color when irradiated with laser light is used, and specifically, a substrate made of polyvinyl chloride (PVC) is used.
As the laser light, a YAG laser (wavelength 1.064 μm) or a CO ₂ laser (wavelength 10.6 μm) is used.

 Here, the color change caused by the laser light irradiation is a color tone different from other parts on the end surface 11c of the core base 11 to such an extent that the color change part can be read as a machine reading code by a general reading device. Say to discolor.

 Note that additives such as pigments, fillers, and plasticizers may be added to the polyvinyl chloride forming the core substrate 11.

 As the surface base materials 12 and 13, a base material made of a material that does not change color even when irradiated with laser light is used. Examples of such a substrate include polyethylene terephthalate (PET) and polyethylene naphthalate (PEN).

 Next, the function of the information card 10 will be described by explaining a method of individually managing by reading the machine reading code 14 formed on each end face 11c in a state where a plurality of information cards 10 are stacked.

 As shown in FIG. 2, for example, when the reading unit 31 of the reading device is held over (contacted with) the mechanical reading code 14 of the information card 10 with two information cards 10 stacked, the reading unit When 31 is substantially parallel to the end surface 11c of the core substrate 11 (indicated by a broken line in FIG. 2), the reading unit 31 can read the machine reading code 14 of one information card 10.

 On the other hand, when the reading unit 31 is obliquely held (contacted) with respect to the end surface 11 c of the core base material 11 (indicated by a two-dot chain line in FIG. 2), the reading unit 31 has two machine reading codes 14. Since the surface base material 12 and the surface base material 13 constituting each information card 10 exist between the two machine reading codes 14, the two pieces of information that are judged as a reading error (miss) and overlapped It is possible to prevent the card 10 from reading (recognizing) the two machine reading codes 14 as one code. Accordingly, the information card 10 can be managed individually by accurately reading each machine reading code 14.

"Information card manufacturing method"
Next, a method for manufacturing the information card 10 will be described.
(1) First Embodiment First, the core substrate 11 made of polyvinyl chloride is cut so as to have a predetermined card shape.
Next, the end surface 11c of the core base material 11 is irradiated with laser light to change the color of the end surface 11c of the core base material 11 to form the machine reading code 14 (step A).

 Next, surface base materials 12 and 13 made of a material different from that of the core base material 11 are bonded to both surfaces of the core base material 11 with an adhesive or fused to both surfaces of the core base material 11. The surface base materials 12 and 13 are laminated (step B) to obtain the information card 10.

(2) Second Embodiment First, the core substrate 11 made of polyvinyl chloride is cut so as to have a predetermined card shape.
Next, surface base materials 12 and 13 made of a material different from that of the core base material 11 are bonded to both surfaces of the core base material 11 with an adhesive or fused to both surfaces of the core base material 11. The surface base materials 12 and 13 are laminated (step B).

 Next, the end surface 11c of the core base material 11 is irradiated with laser light, thereby discoloring the end surface 11c of the core base material 11 to form the machine reading code 14 (step A), and the information card 10 is obtained.

 According to the information card manufacturing method of the first and second embodiments, since a base material made of polyvinyl chloride is used as the core base material 11 and the end surface 11c of the core base material 11 is irradiated with laser light, The machine reading code 14 can be formed only on the end surface 11 c of the material 11. Further, since the base material different from the core base material 11 is used as the surface base materials 12 and 13, even if the end face (side surface) of the surface base materials 12 and 13 is irradiated with laser light, the surface base materials 12 and 13 are used. Therefore, a machine reading code is not formed on the end surfaces of the surface base materials 12 and 13 by mistake.
