Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double-stripe type magnetic card having an embossed portion in the center and magnetic stripes on both sides of the embossed portion.

[0002]

2. Description of the Prior Art This type of double-stripe ID card currently in circulation has an embossed portion in which a number such as a card number is formed in a convex shape at the center of the card.
First and second magnetic stripes are arranged on both sides of the embossed portion and in parallel with the embossed portion. Here, for example, data for realizing a credit card function is recorded on the first magnetic stripe, and data for realizing a cash card function is recorded on the second magnetic stripe. In a card reader that reads data from such a magnetic card, the magnetic head is brought into contact with the first and second magnetic stripes of the magnetic card to read the data.

[0003]

In the card reader for reading data from the magnetic card having the above-described structure, the magnetic head is brought into contact with the first and second magnetic stripes of the magnetic card to read the data. . Therefore, the embossed portion sandwiched between the first and second magnetic stripes and protruding from the surface of these magnetic stripes on the surface of the card strikes against the guide of the card reader and is scraped, and the scraped powder adheres to the magnetic head of the card reader. ,
It is one of the causes of data reading failure.

Therefore, an object of the present invention is to prevent the shavings of the embossed portion from adhering to the magnetic head when reading the data with the magnetic head of the card reader, and to enable the accurate reading of the card data with the magnetic head. And

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a magnetic recording medium in which an embossed portion is formed substantially in the center of a card and data read by a magnetic head of a card reader is recorded. In a double-stripe magnetic card in which stripes are formed on both sides of the embossed portion and in parallel with the embossed portion, the pressure applied by the guide of the card reader to the embossed portion when the data of the magnetic stripe is read by the magnetic head of the card reader. A pressure reducing mechanism for reducing the pressure is provided. In this case, the pressure reducing mechanism is formed between the embossed portion and the magnetic stripe in parallel with the magnetic stripe, and is reduced when pressure is applied to the embossed portion by the guide of the card reader. A groove portion that bends in the direction is provided.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing a configuration of a double-stripe ID card with an embossing protection mechanism to which the present invention is applied. The ID card 1 is a magnetic card, and an embossed portion 2 in which a convex number representing the card number of the magnetic card 1 is formed is provided in the central portion of the card.
Further, a first magnetic stripe 3A and a second magnetic stripe 3B, on which card data such as an ID code is recorded, are provided on the one side and the other side of the ID card 1 which sandwich the embossed portion 2, respectively. It is formed parallel to 2. Further, on both sides of the embossed portion 2, in parallel with the embossed portion 2, groove portions 4A, 4B as a protection mechanism of the embossed portion 2 are provided.
Is provided. Here, for example, data for realizing a credit card function is recorded on the first magnetic stripe 3A, and data for realizing a cash card function is recorded on the second magnetic stripe 3B.

FIG. 2 is a view showing a side surface of the magnetic card 1. The magnetic card 1 has a first magnetic stripe 3A and a second magnetic stripe 3B formed on both end sides thereof, respectively. The above-mentioned embossed portion 2 protruding from the surface of the card is formed substantially in the center of the card. Further, V-shaped groove portions 4A and 4B are formed on both sides of the embossed portion 2.

Further, FIG. 3 is an enlarged view A of the part A shown in FIG.
FIG. 4 is an enlarged side view of the portion, and FIG. 4 is a side view for explaining the function of the groove portions 4A and 4B for reducing the contact pressure when the guide of the card reader comes into contact with the embossed portion 2 when reading data from the magnetic card 1.

2 to 4, this magnetic card 1
The functional operation of the main part will be specifically described. When the magnetic card 1 is inserted into the card reader 5 shown in FIG. 2, the card reader 5 takes in the magnetic card 1 inside, and the magnetic heads 6A and 6B cause the data of the first magnetic stripe 3A and the second magnetic stripe 3B to be read. Read the data. When the data of the magnetic card 1 is read by such a card reader 5, the magnetic heads 6A and 6B are connected to the magnetic stripe 3A,
Since it is necessary to contact the surface 3B, the guide 7 of the card reader 5 hits the embossed portion 2 protruding from the surface of the magnetic card, and the contact pressure P of the guide 7 is applied to the embossed portion 2 as shown in FIG.

When the contact pressure P of the guide 7 of the card reader 5 is applied to the embossed portion 2 of the magnetic card 1 as described above, the contact pressure P of the guide 7 to the embossed portion 2 is reduced as shown in FIG. The groove portions 4A and 4B provided on both sides of the embossed portion 2 are bent in the direction indicated by the arrow.

Due to the bending of the groove portions 4A and 4B, the surface of the embossed portion 2 in a protruding state is lowered from the card surface to the surface position of the magnetic card 1 (that is, the formation position of the magnetic stripes 3A and 3B). The flexure of the grooves 4A and 4B weakens the contact pressure P of the guide 7 on the embossed portion 2, and as a result, the surface of the embossed portion 2 is prevented from being scraped off by the guide 7 of the card reader 5. Therefore, since it is possible to prevent the shavings of the embossed portion 2 from adhering to the magnetic head, it is possible to accurately read the data of the magnetic card 1 by the magnetic head.

In the present embodiment, the card reader 5
When the contact pressure P of the guide 7 on the embossed portion 2 of the magnetic card 1 is weakened, V-shaped groove portions 4A and 4B are formed on both sides of the embossed portion 2, and the embossed portion 2 is bent by the bending of the groove portions 4A and 4B. Contact pressure P to the guide 7
Although the surface of the embossed portion 2 is prevented from being scraped off, the surface of the embossed portion 2 can be similarly prevented from being scraped by another means capable of reducing the contact pressure P to the embossed portion 2.

[0013]

As described above, according to the present invention, the embossed portion is formed in the substantially central portion of the card, and
In a double-stripe type magnetic card in which magnetic stripes on which data to be read by a magnetic head of a card reader is recorded are formed on both sides of the embossed portion and parallel to the embossed portion, the data of the magnetic stripe of the magnetic stripe of the magnetic head of the card reader is Since a pressure reducing mechanism that reduces the pressure applied to the embossed section by the guide of the card reader at the time of reading is provided, when the data is read by the magnetic head of the card reader, the pressure applied to the embossed section of the guide of the card reader It is possible to prevent the embossed portion from being scraped off, and to prevent the scraped powder from adhering to the magnetic head, so that the magnetic head can read the card data accurately. In this case, since the V-shaped groove is formed in parallel with the magnetic stripe as the pressure reducing mechanism, the pressure on the embossed portion of the guide of the card reader can be reduced with a simple configuration.
