Description

[Detailed Description of the Invention] This invention relates to a card with a built-in integrated circuit used for credit cards, cash cards, ID cards, computer program cards, game cards, and the like.

In the past, many proposals have been made regarding the location of the integrated circuit and the location and shape of its input/output terminals in order to ensure that cards with built-in integrated circuits are safe when being carried and installed in a card reader/writer. However, it was not fully satisfactory in actual use.

Therefore, with this design, even if bending force is applied to the card when carrying it, it will not affect the integrated circuit or the integrated circuit terminal, and when it is set in a card reader/writer, bending force will not be applied to the card as much as possible. Furthermore, the present invention provides a card with a built-in integrated circuit that can be used safely by guiding the connector of a card reading/writing machine to the card terminal without placing any load on the integrated circuit terminal itself even if bending force is applied to the card. , Next, an explanation will be given according to the drawings based on an embodiment of this invention.

FIG. 1 shows a card with a built-in integrated circuit according to this invention. A plurality of input/output terminals 3, 3, which are the input/output terminals of the circuit 2, are built in a laminated synthetic resin material, and the top surface of the card, which corresponds to a part of the input/output terminals 3, 3, is circular. The input/output terminals 3, 3 are exposed at the notches 3', 3', and a tapered portion 4' is provided on the left short side 4 of the card 1 as shown in FIG. a surface on the input/output terminal surface side. Note that the tapered part 4' may be provided on a part of the left side of the input/output terminals 3, 3 as shown in FIG. , a printed pattern may be used.

Also, the thickness D from the surface of the input/output terminals 3 and 3 to the surface of the card 1 at the above-mentioned cutout portions 3' and 3'.
(See Figure 4) For use in an insertion-type card reader/writer to be described later, it is important that the thickness be within 0.3 mm, preferably within 0.2 mm.

In the card of this invention constructed as described above, both the integrated circuit and its input/output terminals are located approximately 1/4 inside from the short side of the card, and approximately 2 points from the same short side.
I placed it within the area surrounded by the diagonal line of the book, so
Even when a normal bending force is applied to the card, it is concentrated on the longitudinal center and diagonal lines of the card, and has little effect on the integrated circuit and its input/output terminals 3, 3. When inserting the card into a card reading/writing machine that has an insertion type connector to connect it to the input/output terminals 3 and 3 of the card, no load is applied to the card terminal, and the resistance force by the connector is weakened by the tapered surface of the tapered part. At the same time, the connector can be guided smoothly to the card terminal, and the force that bends the card itself is weakened.
Moreover, since the integrated circuit and the input/output terminals are provided within the range surrounded by the same short side and approximately two diagonal lines, the influence on them is reduced, and the safety in carrying is increased.
