Abstract

PURPOSE:To increase a degree of freedom in selecting an insertion of a card to a card applied terminal. CONSTITUTION:On an IC card 1, two or more modules 2, 3 having electric contact terminals are mounted. An IC is mounted on one of the modules. The corresponding electric contact terminals of the respective modules are connected to each other. In this manner, the same function as that obtained by mounting a plurality of ICs is obtained. Therefore, an insertion direction of the IC card to an IC card applied terminal is increased in number by the number of modules, and an insertion error is reduced.

[Detailed description of the invention]

0001

[Industrial Application Field] This invention relates to integrated circuits (hereinafter referred to as IC).
This relates to an IC card that has a built-in card.

2. Description of the Related Art FIG. 6 is a plan view showing a conventional IC card disclosed in, for example, Japanese Patent Publication No. 53-6491. In the figure, 1 is an IC card body, 2 is a module having an IC and electrical contact electrodes It is. In FIG. 7, a and b are a plan view and a sectional view showing an example of a module, and in the figure, 4
is an IC built in the module 2, and 5 is an electric contact electrode. FIG. 8 shows an application terminal 6 into which an IC card is inserted and applied, and 7 is a terminal that makes electrical contact with the electrode 5 of the IC card.

[0003] That is, each IC card 1 has a built-in module 2 with an electrode, and such an IC card must be inserted into an application terminal 6 in order to activate its built-in functions. This supplies the necessary power and signals to the IC card, and the IC card operates based on the operation of the built-in IC. This requires that the electrodes 5 of the IC card and the terminals 7 of the application terminal 6 come into electrical contact, but the application terminal 6 usually has a built-in set of terminals 7, and the electrodes of the IC card come into contact with each other. It is necessary to determine the direction and insert it. Current ISO (International Organization for Standardization)
In this case, the electrode positions on the IC card are determined, and are eccentrically located on both the left and right sides from the center line of the card.

0004

[Problem to be solved by the invention] As described above, the conventional I
Since the C card has one module with electrodes mounted on one IC card, only one direction is allowed for insertion into the application terminal, and no other I/O card can be inserted into the application terminal.
If you insert the C card in the direction of the
There was a problem in that the original function of the C card could not be used.

[0005] This invention was made in order to solve the above-mentioned problems, and its purpose is to obtain an IC card that allows insertion in at least two directions instead of the conventional one direction. There is.

[0006]

[Means for Solving the Problems] An IC card according to the present invention has one module consisting of an IC and an electric contact terminal, and a separate module consisting of only an electric contact terminal mounted on one IC card. , these modules are electrically connected.

[0007]

[Operation] In this invention, a module consisting of an IC and an electric contact terminal and a module consisting only of an electric contact terminal without an IC are connected to each other with the same contact terminals by wiring, so that one IC has two electric contacts. It will be electrically connected to the contact terminal, and when the electrical contact terminal of one of the two modules comes into contact with the electrode of the application terminal,
Can have the same functionality.

[0008]

[Example] Example 1. FIG. 1 shows an embodiment in which module 2 and module 3 are mounted in symmetrical positions rotated 180 degrees around the longitudinal center line C1 of the card, and I
C is mounted on either module 1 or 3, and when the electrical contact terminal of either module 2 or 3 comes into contact with the electrode terminal of the application terminal, it can have the function of an IC card. That is, in this case, the degree of freedom in the direction of inserting the IC card into the application terminal is twice that of the conventional method. In this case, the position and electrical function of each of the electrical contact terminals of module 2 and module 3 are 1 with the center line C1 as the axis.
If you rotate it 80 degrees, it will be in the same position, and its functions will also correspond.

FIG. 2 shows how the electrical contact terminals of modules 2 and 3 have the same function and positional relationship, and are connected by a circuit. That is, in FIG. 2, the electrical contact terminals 11 and 12 and 13 and 14 are in the same positional relationship when rotated by 180 degrees. These terminals 11 and 12 and 13 and 1
4 are connected by a circuit and have exactly the same electrical functions. Note that the other six electrical contact terminals are also connected in the same way, so even if the modules are different, each electrical contact terminal can have the same function. Note that the circuit connections between the modules 2 and 3 employ highly densely bundled wiring as shown at 8 in FIG. For example, flexible wiring made of polyimide resin plated with copper foil is used.

Example 2. Next, Figure 3 shows modules 2 and 3.
An embodiment is shown in which the card is mounted so that it is located at the same position when rotated by 180 degrees around the longitudinal center line C2 of the card.

Example 3. Further, FIG. 4 shows an embodiment in which the card is mounted in the same position when rotated 180 degrees around a center line perpendicular to the card surface.

Example 4. FIG. 5 shows an embodiment in which four modules are mounted, an IC is mounted on one of them, and the four modules are connected by a circuit. Since each of the four modules can have the same function, all insertion directions (four directions) are allowed when this IC card is inserted into an application terminal. This eliminates the hassle of inserting the IC card into the application terminal after confirming the position of the electrical contact terminals of the module.

[0013]

[Effects of the Invention] As described above, according to the present invention, since a card having a plurality of modules and one IC mounted thereon is configured, the degree of freedom in selecting a card to be inserted into an application terminal is increased by the number of modules. Therefore, it has the effect of making it extremely easy to use.
