BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information recording card such as an IC card and an optical card used in a payment system using a card.

[0002]

2. Description of the Related Art In recent years, as prepaid cards and the like, IC cards and other cards capable of additionally recording data have become popular in place of magnetic cards. In this type of card, it is required to be able to easily visually determine that the card is unused. This is to prevent a card sales shop or a clerk at a card shop from handling a card that has already been used or has been used (hereinafter referred to as an already-used card) as an unused card. Conventionally, a punch hole indicating a balance is punched in a card, and it is visually determined whether the card is an unused card or a used card depending on the presence or absence of the punch hole.

[0003]

However, a card such as an IC card capable of writing information may be thicker than a magnetic card or the like and may be made of a hard material. Therefore, there is a problem that a conventional punching device for punching a card cannot be used. Moreover, when a punch hole is formed in the card, dust such as punch dust generated when forming the punch hole must be collected, and the treatment of the dust is also a problem. In addition, the distinction based on punched holes is such that the punched holes made in the card are blocked and the card is made to appear as an unused card.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide an information recording card which can determine whether it is unused or unused very easily, and which is easy to dispose of dust. I am trying.

[0005]

In order to achieve the above object, the information recording card according to claim 1 is an information recording card in which a storage medium capable of reading and writing information is provided in a substrate, on the surface or back surface of said substrate, at least the power supply contacts to the storage medium, the result in writing contact information to the reading contacts and the storage medium information of the storage medium is provided, it said reading contacts
And a contact hole is formed at the position where the power supply contact is arranged.
The formed sheet is attached to the substrate by pressure bonding.

In other words, when used, the sheet must be peeled off to expose the contacts in order to read and write the information in the internal storage medium. Therefore, by checking the presence or absence of this sheet, this information can be read. It is possible to judge whether the recording card is an unused card which has not been used yet, or an already used card which has already been used or has been used. Also,
Since the sheet is attached by pressure bonding that cannot be reattached, it is possible to prevent the unused card from being pasted again to the used card whose sheet has been peeled off. In addition, the reading provided on the substrate
A contact hole is formed at the location of the contact for power supply and the contact for power supply.
The formed sheet is attached to the substrate by pressure bonding.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of an information recording card of the present invention will be described below with reference to the drawings. First of all, it has a plurality of contacts, power supply, information writing,
A contact type IC card for reading will be described as an example. In FIG. 1, reference numeral 1 is an IC card (information recording card). This IC card 1 has a substrate 1
The sheet 2 is attached to the surface of a. The sheet 2 is formed of resin, paper, or the like, which has biodegradability that naturally decomposes and has an insulating property, and is attached to the substrate 1a of the IC card 1 by pressure bonding.

In the IC card 1, as shown in FIG.
A contact point 3 is provided on the portion where the sheet 2 is attached. The contacts 3 are a writing contact 3A for recording information in a storage medium (not shown) provided in the IC card 1, a reading contact 3B for reading information recorded in the storage medium in the IC card 1, and an IC. There is a power supply contact 3C for supplying electric power for operating the storage medium in the card 1.

As described above, the plurality of contacts 3 are covered with the sheet 2 attached by pressure bonding to the surface of the substrate 1a of the IC card 1. Also,
On this sheet 2, contact holes 4 are formed at the positions where the reading contacts 3B and the power supply contacts 3C are arranged.

When using the IC card 1 described above, the card user removes the sheet 2 attached to the IC card 1 and uses it. In other words, this sheet 2
When peeled off, all the contacts 3 of the IC card 1 are exposed,
As a result, it becomes possible to read and write the information by a reading device or a depositing machine that reads and writes the record information recorded in the storage medium in the IC card 1.

Further, by peeling the sheet 2 from the IC card 1 as described above, it is possible to visually confirm that the IC card 1 is in use or has been used. That is, it is possible to determine that the IC card 1 to which the sheet 2 is attached is unused.
The IC card 1 from which the sheet 2 has been peeled off can be determined to be already used.

Here, in this IC card 1, the contents recorded in the unused IC card 1 may be confirmed after visually confirming that the IC card 1 is unused or used. In this case, this sheet is used. IC card 1 with 2 attached
To the reading device. By doing so, the IC card 1 is supplied with power from the power supply contact 3C through the contact hole 4 of the sheet 2 formed at the position where the power supply contact 3C is arranged, and also has a read contact. Information is read from the reading contact 3B through the contact hole 4 of the sheet 2 formed at the arrangement position of 3B.

At this time, since the writing contact 3A of the IC card 1 is covered with the sheet 2, it is not possible to write information to the IC card 1. In other words, the IC card 1 can read only the information recorded in the storage medium, even if the IC card 1 is an unused one to which the sheet 2 is attached.

As described above, according to the IC card 1 described above, when the IC card 1 is used, the sheet 2 must be peeled off to expose the contact 3 in order to read and write the information in the internal storage medium. By checking the presence or absence of this sheet 2, this information recording card 1
It is extremely easy to determine whether it is an unused card that has not been used yet, or an already used card that has already been used or has been used.

Moreover, since the sheet 2 is attached by pressure bonding that cannot be reattached, the used card from which the sheet 2 is once peeled off is attached again to make it look like an unused card. Can be prevented. Furthermore, by forming the contact holes 4 in the sheet 2 at the positions where the reading contacts 3B and the power supply contacts 3C are arranged, only the portion including the information writing contacts 3A is covered by the sheet 2. Therefore, only the information recorded in the storage medium can be read, and the recorded information of the unused card to which the sheet 2 is attached can be read and confirmed.

Since the sheet 2 has biodegradability, the peeled sheet 2 is naturally decomposed. That is,
The influence of the peeled sheet 2 on the environment can be suppressed.

In the above example, the reading contact 3
B, the contact holes 4 are formed in the sheet 2 at the positions where the power supply contacts 3C are arranged.
The contact 3 other than the power supply contact 3C may be covered with the sheet 2. That is, the sheet 2 may be attached so as to cover at least a part of the plurality of contacts 3 of the IC card 1 including the writing contact 3A.

Next, a non-contact type I, which has a built-in antenna, is used to generate information by this antenna and to transmit and receive information.
The C card will be described as an example. As shown in FIG. 3, this IC card 1A has a loop-shaped antenna 11 provided inside a substrate 1a, and when magnetic energy from an external device acts on the surface of this IC card 1A,
Electromotive force is generated by electromagnetic induction of the antenna 11, and the electric power is used to read information from a storage medium (not shown) provided in the substrate 1a and write information to the storage medium.

The IC card 1A has a substrate 1a.
On the surface of the substrate 1a, a sheet 12 formed of resin, paper or the like, which has biodegradability that spontaneously decomposes and is non-permeable, that is, which has the property of blocking the energy of magnetic force from the outside, It is attached by pressure bonding. The sheet 12 covers part of the arrangement position of the antenna 11 provided on the substrate 1a.

In this IC card 1A, the voltage value required for reading is different from the voltage value required for writing, and the voltage value required for writing is higher than the voltage value required for reading. Has been made larger. Since the sheet 12 partially covers the antenna 11, the voltage value of the electromotive force generated by the antenna 11 is set to be equal to or higher than the voltage value required for reading and lower than the voltage value required for writing. ing.

When using the above IC card 1A, the card user peels off the sheet 12 attached to the IC card 1A and uses it. That is, when the sheet 12 is peeled off, the antenna 12 of the IC card 1A
Electromagnetic induction is possible in all ranges of the above, and it is possible to read and write information by a reading device or a depositing machine that reads and writes recorded information recorded on the storage medium in the IC card 1. Becomes

Further, by peeling the sheet 12 from the IC card 1A, the IC card 1A is
It is possible to visually confirm that the product is in use or has already been used. That is, it can be determined that the IC card 1A to which the sheet 12 is attached is unused, and the IC card 1A from which the sheet 12 is peeled off is
It can be determined that it is already used.

Here, as described above, in this IC card 1A, the contents of the information recorded in the storage medium of the unused IC card 1A are confirmed after visually confirming that the IC card is unused or unused. In some cases, the IC card 1A to which the sheet 12 is attached is inserted into a reading device or the like. By doing this, the IC card 1A
Electric power is generated in a portion of the antenna 11 other than the portion covered by the sheet 12, and the recorded information is transmitted to the reading device by the electric power. As a result, the reading device reads the information recorded in the storage medium of the IC card 1A.

At this time, since the antenna 11 covered with the sheet 12 does not generate a voltage sufficient for writing, information cannot be written in the storage medium of the IC card 1A. That is, even if the IC card 1A is an unused one with the sheet 12 attached, it is possible to read only the recorded information by the reading device.

As described above, according to the above IC card 1A, when used, the sheet 12 is peeled off so that electromagnetic induction can be performed by the antenna 11 in order to read and write information in the internal storage medium. Therefore, by checking the presence / absence of this sheet 12, the information recording card 1A is an unused card that has not been used yet, or a used card that has already been used or has been used. Can be determined very easily.

Moreover, since the sheet 12 is attached by pressure bonding which cannot be reattached, the sheet 1 is temporarily attached.
It is possible to prevent the unused card from being peeled off by attaching the sheet 12 to the used card from which the sheet 2 has been peeled off. In addition, the unused card, antenna 1
When the power is generated by 1, only the reading can be performed by this electromotive force, so that the recorded information of the unused card to which the sheet 12 is attached can be read and confirmed.

Since the sheet 12 has biodegradability, the peeled sheet 12 is naturally decomposed. That is, the influence of the peeled sheet 12 on the environment can be suppressed.

In the above example, the sheet 12 covers a part of the position where the antenna 11 is arranged. However, as the non-contact type IC card 1A, as shown in FIG. Alternatively, a predetermined number of the antennas 11 among the plurality of antennas 11 may be installed and the positions where the antennas 11 are arranged may be covered with the sheet 12. In other words, this sheet 12 covers a predetermined number of the antennas 11 at positions where the voltage value of the electromotive force due to the electromagnetic induction of all the antennas 11 is set to be equal to or higher than the voltage value required for reading, and more By lowering
Only the reading may be performed in the unused state where the sheet 12 is attached.

Further, in the above IC card 1A, the antenna 11 which receives the energy of the magnetic force from the outside and generates the electric power by the electromagnetic induction is provided. Needless to say, it may be one that generates electric power by electric induction.

Further, as the sheets 2 and 12, a sheet in which a plurality of cuts are formed so as not to be reused and which is divided into a plurality of pieces when peeled off may be used, or they are dissolved by water, chemicals or the like. A material may be used, and the material may be dissolved to be peeled off. Alternatively, the sheets 2 and 12 may be coated with an insulating material or a material having non-permeability so that the sheets 2 and 12 have insulating properties and non-permeability. Furthermore, the contact 3 of the IC card 1 and the IC
The surface of the card 1A on the side receiving the magnetic force by the antenna 11 is
Not only the front surface but also the back surface may be used.
