Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a portable storage medium such as a multifunctional IC card.

(Prior Art) Multifunctional IC cards have conventionally been used as portable storage media containing electronic components such as a CPU and memory. This multifunctional I
The C card has convex characters (embossed characters) on the exterior surface of the card that indicate the name of the card user, the expiration date of the card, and the like. Conventionally, as a method for creating embossed characters, as shown in FIG. 4, an embossed pedestal 31 on the top 5 is adhered to the exterior panel 1 forming the card exterior using an adhesive, for example. A method has been proposed in which desired embossed characters are created by cutting this embossed base with a cutter attached to a spindle motor (see Japanese Patent Laid-Open No. 178089/1989).
.

However, with a multi-function IC card like the one configured above,
When adhering the embossed pedestal onto the exterior surface, conditions such as temperature and pressure had to be taken into consideration. Furthermore, if an external force is applied to the multifunctional IC card body, there is a risk that the embossed pedestal adhered to the exterior surface will peel off and fall off.

(Problem to be Solved by the Invention) As mentioned above, in conventional multifunctional IC cards, there is a risk that the embossed base may peel off from the outer surface of the card and fall off when external force is applied to the card body. There was a problem.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a portable storage medium in which there is no risk of the embossed pedestal peeling off from the card exterior surface and falling off from the card body.

[Structure of the Invention (Means for Solving the Problem) In order to achieve the above object, the present invention provides a portable storage device having an embossed base for creating embossed characters on the outer surface of an exterior plate constituting a card base. In the medium, the exterior plate has an opening, and the member forming the embossed pedestal is configured to be continuous with the inner surface of the exterior plate through the opening.

(Function) In the above configuration, the portable storage medium has an exterior plate, and this exterior plate is provided with an opening. An embossed pedestal formed by a continuous member from the inner surface of the exterior plate (inside the card) is fitted into the opening of the exterior plate. As a result, the embossed pedestal portion protrudes to the outside of the exterior plate of the portable storage medium.

(Example) Hereinafter, an example in which the present invention is applied to a multi-function IC card will be described in detail with reference to the drawings.

First, a multifunctional IC card 10 as a portable storage medium.
The configuration of is shown in FIGS. 1 and 2. Here, FIG. 1 is a front view of the multifunction IC card 10, and FIG. 2 is a sectional view taken along the line A-A'' of the multifunction IC card 10 shown in FIG.

The main body of the multifunctional IC card 10 has an exterior made of a metal exterior panel 1, a resin sheet 2, and a frame 3. Here, the frame 3 is made of resin, and an embossed pedestal 31 for forming embossed characters is integrally molded therein. The exterior panel 1 and the resin sheet 2 are bonded to the frame 3 using an adhesive or the like. this house,
An opening 11 is provided in the exterior panel 1 at a portion corresponding to the embossed pedestal 31 of the frame 3. This exterior panel 1 is glued to the embossing pedestal 31 side of the frame 3,
An embossed pedestal 31 provided on the frame 3 and an opening 11 provided on the exterior panel 1 are fitted together.

Inside the card 10, that is, in the space surrounded by the exterior panel 1, the resin sheet 2, and the frame 3, the LS
A board 6 on which I5 is mounted, a keyboard module 7,
An anisotropic conductive film in which electronic components such as the liquid crystal display board 8 are not shown;
They are connected and mounted by wire bonding, soldering, etc. Here, the resin sheet 2 has a numeric keypad printed on it, and also functions as a key top member of the keyboard module 7.

Now, on the embossed pedestal 31 provided on the frame 3,
"Cardholder name" is processed by cutting with a cutter attached to a spindle motor (not shown).
Embossed characters such as "card expiration date" are formed. Here, as described above, the exterior panel 1 is adhered to the frame 3, and the opening 1 provided in the exterior panel 1
1 and an embossing pedestal 31 provided on the frame 3 are fitted. That is, the members constituting the embossing base 31 continue into the card 10 through the opening of the exterior panel 1, and each row of the embossing base 31 is integrally molded within the card.

With the above configuration, the multifunctional IC card 10 of this embodiment has no fear that the embossed pedestal 31 will peel off from the card 10 and fall off even if an external force is applied to the embossed pedestal 31. . Further, since the embossing base 31 is integrally molded with the frame 3, there is no need to perform the step of gluing a member used as an embossing base onto the exterior panel as in the conventional case. Therefore, there is no need to consider conditions such as bonding temperature and pressure that were used when bonding the embossed pedestal, and the manufacturing cost when manufacturing the multifunctional IC card can be reduced.

Note that, as shown in FIG. 3, even if the opening 11 provided in the exterior panel 1 is continuous to the outer periphery of the card 10, there is no problem in obtaining the above effect.

[Effects of the Invention] As described above, in the portable storage medium of the present invention, the member constituting the embossed pedestal for forming embossed characters is continuous to the inside of the card through the opening of the exterior panel. . Thereby, it is possible to provide a portable storage medium in which there is no risk of the embossing base falling off even if an external force is applied to the embossing base.
