Description

[Detailed Description of the Invention] [(Already needed)] Regarding a magnetic recording medium reading device that can read magnetic recording media having different coercive forces using a current value corresponding to the respective anti-coercive forces, The purpose of the present invention is to provide a magnetic recording medium reading device that can read recorded data from multiple types of magnetic recording media having different coercive forces using a magnetic head that is energized with a current corresponding to the coercive force. , comprising a measuring means for measuring the coercive force of a magnetic recording medium and a storage means for storing current values corresponding to different coercive forces of a plurality of types of magnetic recording media; A current value corresponding to the coercive force stored in the means is selected, and the magnetic head is energized with the selected current value.

[Industrial application field]

The present invention relates to a magnetic recording medium reading device for an automatic transaction device that handles multiple types of transactions in financial institutions, etc., and is particularly capable of reading magnetic recording media having different coercive forces using current values corresponding to the respective coercive forces. The present invention relates to a magnetic recording medium reading device.

In recent years, financial institutions have introduced automated teller machines that customers operate to conduct transactions.
Machines (hereinafter referred to as ATMs) and automatic teller machines (Cash Dispensers: hereinafter referred to as CDs)
The first class automatic transaction device is a magnetic card (hereinafter referred to as a card)
However, recently, devices that can handle transfers in addition to normal transactions such as deposits, payments, and bookkeeping have become popular.

In the case of a transfer, a special transfer card is provided for a specific transfer recipient, but the magnetic stripe on this card has a different magnetic coercive force than a normal transaction card, and the card issued by the financial institution using the device cannot be used by other device manufacturers. Since this cannot be used in financial institutions that use this type of device, a method that can be used with cards having different coercive forces is desired.

[Conventional technology]

Figure 4 (a) is an interbank unified card (JIS-II type), which has a magnetic stripe 1a with a coercive force of 650Hc on the surface and is used for normal transactions at financial institutions, such as payments, deposits, balance inquiries, etc. Ru.

Figure 4 (bl is an ISO card (JIS-1 type), with a coercive force of 270 Hc on the back, which is wider than a unified interbank card.
It has a magnetic stripe 1b and is used, for example, in distribution-related transactions. In other words, in relation to distribution by customers! ! l
Used for cooperative transactions where ¥2 is settled at a bank.

Figure 5 shows the main parts of a card reading device built into a transaction device such as an ATM. It consists of a card read/write (hereinafter referred to as CR/W) section equipped with heads 5a and 51), and a transport path 6.

The card detection magnetic head 3a and the R/W head 5a are energized with a current corresponding to the magnetic stripe 1a of the unified interbank card to perform CR/W.

The card detection magnetic head 3b and the R/W head 5b are
A current corresponding to the magnetic stripe 1b of the SO card is applied to perform CR/W.

Therefore, when a card is inserted through the insertion slot 2, the card detection magnetic heads 3a and 3b detect the front and back of the card.

The insertion direction and the tips of the magnetic stripes la and 1b are magnetically detected and transported through the transport path 6, and in the CR/W section 4, one of the R/W heads 5a and 5b on the detected side is provided with a magnetic strip (not shown). A current of a corresponding current value is applied from the CR/W control unit, the recorded data is read, and the transaction is proceeded based on the read data.

Now, devices that handle transfer transactions in addition to regular transactions are becoming widespread in banks, etc., and transfer-only cards with a designated transfer destination are now being used. magnetic stripe 1b
There are two types of cards in use: one with a magnetic stripe 1aG on the back, and the other with the magnetic stripe 1aG of the unified banking card on the back. This is because the supported functions differ depending on the device manufacturer.
Each adaptive device is equipped with a CR/W unit exclusively for transfers, which includes a card insertion slot exclusively for transfers.

[Problem that the invention seeks to solve]

According to the above-mentioned conventional method, since a CR/W unit compatible with a transfer-only card is added, extra space is required in the device, and moreover, it is costly.

Also, because magnetic stripes with different coercive forces are used, transactions can only be made at banks that have compatible equipment installed.
The problem is that it is extremely inconvenient.

An object of the present invention is to provide a magnetic recording medium reading device that can handle magnetic recording media having different coercive forces.
