Description

The present invention relates to a process for the production of electrical card comprising a module having a circuit or sheet type information medium body.

In recent years, with the progress of the information-oriented society, information is recorded on a card, and information management and settlement using the card are performed.
Examples of such a card used for information management and settlement include an IC card with an IC chip built therein, a magnetic card on which information is written by magnetism, and the like. In these card-type information media such as IC cards and magnetic cards, information is written and read using a dedicated device.

 Such a card type information medium is provided with an emboss display in addition to a display such as printing. On the surface of the information medium, for example, display information unique to the information medium, the name of the owner of the information medium, the number of the information medium, the membership number, the expiration date of the information medium, etc. (Embossed characters) are formed. This embossed character displays information specific to the information medium and is used as visible information.

 Embossing is usually performed on a card-type information medium from the back side by using a key for embossing on which a character pattern is formed, and the card base on the front side of the information medium. This is a method in which a material is raised in a convex shape to form desired character information as an embossed character (see, for example, Patent Document 1). In this method, the character pattern is formed in a concave shape on the back side of the information medium.

 In addition, as a method of providing embossed characters on a card-type information medium, embossed characters are formed in advance by embossing the card base material, and then embossed via other built-in components (modules). A method of bonding a base material and another card base material is known (see, for example, Patent Document 2).

In the method of directly embossing the information medium, it is necessary to dispose the module while avoiding the portion to be embossed, so that the shape of the module is limited. Therefore, the original function of the information medium may be impaired.
In addition, in the method of embossing the card base material in advance, when the base material subjected to the embossing process and another card base material are bonded together, the card base material is formed on the back surface side (the inner side at the time of sticking). There is a problem that air is confined in the recess corresponding to the embossed character, and an air layer is formed in the recess. When an air layer is formed in the recess, the strength of the embossed character portion is lowered, and the portion may be depressed, resulting in poor quality.

In this step c, the second substrate 15 is superimposed on the first substrate 14 so that the other surface 14b of the first substrate 14 and the other surface 15b of the second substrate 15 face each other.
By this step, the first adhesive 20 is spread (applied) on almost the entire other surface 14 b of the first base material 14 and the other surface 15 b of the second base material 15.

Next, as shown in FIG. 17, a substantially rectangular frame 11 </ b> A that penetrates in the thickness direction and has an insertion portion 11 a having substantially the same shape as the outer shape of the module 12 is prepared.
Then, the second base material 15 is formed by superimposing the frame 11 </ b> A on the other surface 15 b of the second base material 15 via the first adhesive 20 and pressing the frame 11 </ b> A against the second base material 15. The first adhesive 20 is spread between the frame 11A and the frame 11A, and the frame 11A is bonded to the other surface 15b of the second substrate 15 (step d).

Here, the outline 10 a of the information medium 10 corresponds to the outline 19 a of the print layer 19.
In this step d, when the first adhesive 20 is developed between the second base material 15 and the frame 11A, the first adhesive 20 may be caused to flow into the fitting portion 11a of the frame 11A.
Moreover, in this process d, the excess part of the 1st adhesive agent 20 expand | deployed between the 2nd base material 15 and the flame | frame 11A is outside the outer line 10a of the information medium 10 (outer line 19a of the printing layer 19). Then, expand the hem.

 Next, as shown in FIG. 18, the module 12 is inserted into the insertion portion 11a formed inside the frame 11A (step e).

Next, as shown in FIG. 19, the surface of the frame 11 </ b> A opposite to the surface facing the second base material 15 (hereinafter referred to as “one surface”) 11 b and the second base material of the module 12. The second adhesive 21 discharged from the nozzle 32 of the adhesive application device is applied to the surface (hereinafter referred to as “one surface”) 12a opposite to the surface facing 15 (step f).
In this step f, the application position of the second adhesive 21 is preferably a position corresponding to the recesses 17A, 17B, 17C, 17D, and 17E formed on the first base material 14.

As the 2nd adhesive agent 21, the thing similar to the adhesive agent which forms said adhesive layer 13 is used.
The amount of the second adhesive 21 applied to the one surface 11b of the frame 11A and the one surface 12a of the module 12 is not particularly limited, but the frame 11A is covered with the second adhesive 21. It is appropriately adjusted according to the area, the size of the module 12, and the like.

 Next, as illustrated in FIG. 20, the surface of the first base material 14 on which the first adhesive 20 is applied to the frame 11 </ b> A and the module 12 via the second adhesive 21 applied to the frame 11 </ b> A and the module 12 ( The second adhesive 14b is placed between the frame 11A and the module 12 and the first substrate 14 by overlapping the other surface 14b) and pressing the first substrate 14 against the frame 11A and the module 12. 21 is developed (step g).
