Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a card for a public telephone, and more particularly to a card for a public telephone incorporating an IC chip and an antenna.

[0002]

2. Description of the Related Art Conventionally, magnetic cards have been commonly used as cards for public telephones. However, magnetic cards have been relatively easily forged or remodeled, causing various troubles.
Therefore, the use of an IC card instead of a magnetic card as a card for a public telephone has been studied.

[0003]

When this IC card is used as a card for a public telephone, if it is formed in the same shape as a conventional magnetic card, it is difficult to distinguish between the IC card and the magnetic card. There is a problem that causes a problem.

[0004] It is an object of the present invention to provide a card for a public telephone in which such a disadvantage of the prior art is solved and a discrimination from a magnetic card is made clearly.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a flexible card substrate having the same shape and dimensions as a magnetic card for a public telephone, and an IC chip and an electrical connection with the IC chip. A built-in antenna for communicating signals with the public telephone and receiving power from the public telephone is provided, and a notch for distinguishing the magnetic card from the magnetic card is provided in a peripheral portion of the card board in the longitudinal direction. It is characterized by having been provided.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the present invention will be described with reference to FIG. The card for public telephone according to this embodiment includes a flexible thin card substrate 1 having substantially the same shape and dimensions as the magnetic card for public telephone, for example, the number of calls (or the number of calls), or a fake or modified product. A flaky IC chip 2 storing identification information indicating that the card is a genuine public telephone card,
An antenna 3 electrically connected to the IC chip 2 to exchange signals with a public telephone (not shown) and receive electric power from the public telephone; Are built into the card substrate 1.

The installation position of the IC chip 2 is
Near the corner of the card substrate 1 shifted from the central portion 4 in the longitudinal direction, and corresponds to a card holding portion (not shown) such as a pair of transport rollers or a pair of a magnetic head and a pad roller in a public telephone. It is specified at a position outside the portion 5.

[0010] The antenna 3 is formed of a linear body which is formed in a substantially square shape so as to be point-symmetrical about the center O of the card substrate 1 by printing. An antenna having the same shape as the antenna 3 is also provided in the public telephone, and communication and power supply are performed by electromagnetic coupling of both antennas.

If the antenna 3 is formed symmetrically with respect to the center O of the card substrate 1 as in this embodiment, the card can be turned upside down from the front or back from the public telephone. Even if inserted, communication and power supply are possible. The installation position of the antenna 3 is specified at a position deviating from the portion 5 corresponding to the card holding portion and a position deviating from a region 6 in which a through-hole indicating the usage frequency (remaining frequency) of the card is formed. .

At the center of the long edges 7, 7 on both sides of the card substrate 1, arc-shaped notches 8, 8 for distinguishing the magnetic cards for a public telephone from each other are formed so as to face each other. In the case of a magnetic card for a public telephone, the notch is formed at one short edge of the card substrate, and the notch 8 can be distinguished from a magnetic card.

The card for a public telephone according to this embodiment has a communicable frequency of 100 degrees, the notch 8 is formed in the long edge 7 on both sides as described above. A cutout 8 is formed only in the long edge 7, and the number of the cutouts 8 makes it possible to discriminate between the communicable frequencies (100 degrees and 50 degrees) and to identify the card type.

[0012] Since the card for a public telephone is flexible, it is easily subjected to deformation such as bending. For this reason, bending stress is generated in the built-in IC chip 2 or a connection portion between the built-in IC chip 2 and the antenna 3, and there is a concern that the card is broken. In the present embodiment, in order to avoid this, the IC chip 2 is located at a position away from the central portion 4 in the longitudinal direction of the card substrate 1 where the card is likely to bend frequently, preferably near the corner of the card substrate 1.
Is installed. Further, the notch 8 is provided in the central portion 4 of the card substrate 1 to reduce the mechanical strength in the vicinity of the notch 8, to specify a bent portion when an external force is applied, and to connect the IC chip 2 or the antenna 3 with the IC chip 2. So that bending stress is not generated.

In the present embodiment, the notch 8 is provided in the center 4, but the notch 8 is formed from the center 4 of the short edge 9 on the side where the IC chip 2 is not installed. The cutout 8 may be formed anywhere within the range 10 between the IC chips 2, that is, at a position as far away from the IC chip 2 as possible.

In forming the plurality of cutouts 8, the cutouts 8 are formed so as to face each other in the present embodiment. However, the cutouts 8 may be formed side by side with one long edge 7. Further, in the present embodiment, the arc-shaped notch 8 is provided, but the shape of the notch 8 may be another shape such as a polygon of a triangle or more.

[0015]

According to the first aspect of the present invention, as described above,
An IC chip and its IC are mounted on a flexible card substrate having substantially the same shape and dimensions as a magnetic card for a public telephone.
An antenna for electrically communicating with the chip and communicating with the public telephone and receiving power from the public telephone is built in, and a peripheral portion in the longitudinal direction of the card board is provided.
A notch is provided for distinguishing the magnetic card from the magnetic card. Therefore, it can be distinguished from a magnetic card for a public telephone, and no trouble occurs in use or the like.

According to the second aspect of the present invention, if the installation position of the IC chip is shifted from the central portion in the longitudinal direction of the card substrate, the generation of bending stress in the IC chip and the connection between the IC chip and the antenna can be reduced. Those damages can be prevented.

According to a third aspect of the present invention, if the notch is formed between the longitudinal center of the card substrate and the short edge on the side where the IC chip is not installed, an external force is applied to the card. Since the bent portion is specified when the IC chip is separated from the IC chip, the generation of bending stress in the IC chip and the connecting portion between the IC chip and the antenna can be reduced, and their damage can be prevented.

If the notches are provided so as to substantially oppose both long edges of the card substrate, the card is likely to be bent at the opposing portions, so that the IC chip and the antenna and the IC chip can be bent. The occurrence of bending stress at the connection with the wire can be reduced, and their damage can be prevented.

According to a fifth aspect of the present invention, if the notch also serves as a notch for discriminating the number of possible calls,
The number of notches to be formed is small, so the shape of the blade that cuts the card board from the board material is not complicated,
Less wear on the blade.

As described in the sixth and seventh aspects, if the installation position of the IC chip and the antenna deviates from the position corresponding to the card holding portion of the public telephone, the IC chip and the antenna are pressed by the pressing force of the card holding portion. Damage can be prevented.

If the installation position of the antenna is out of the area where the through-hole indicating the card usage frequency is formed, the antenna may be damaged or cut by the formation of the through-hole. It has features such as no worries.
