Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a reading device for a magnetic card such as a cash card or a credit card, and in particular to a magnetic card reading device for magnetic cards such as cashier cards or credit cards, and in particular for reading magnetic cards of different standards such as JISI and JIS 1. The present invention relates to a magnetic card reading device capable of reading 11 7.21 condolences.

[Technology background]

There are two standards for magnetic cards used for Cadge Island cards, credit cards, etc.: JIS I and JIS I. JIS N standard magnetic cards.

This is a format mainly used in foreign countries.

A magnetic stripe is provided on the back of the card. and 3
The second track consists of 5 bits per character. On the other hand, a JIS 1 standard magnetic card is a format mainly used in Japan, and a magnetic stripe is provided on the front side of the card. Basically, it consists of one track, and one character consists of 8 bits.

Also, both of them are data four! There are also differences in terms of cut.

By the way, recently, as the use of Cage Island cards and credit cards has expanded, the types of cards have diversified, and in addition to those that comply with the JIS N standard, there are also cards that comply with the JIa I standard or both JIS I and JI8I standards. As more and more problems arise, the commonly used JISI magnetic card reading devices and interfaces are no longer able to handle them.

Conventionally, in order to read these two types of magnetic cards, it has been necessary to provide independent magnetic card reading devices and interfaces for each standard, as illustrated in FIG.

In Figure 1, 1 is a JIS l magnetic card reader (MCR), 2 is a JIS l magnetic card reader (MCR), and 2 is a JIS l magnetic card reader (MCR).

6 is a CPU.

However, if separate magnetic card reading devices and interfaces are provided for JIS I and JIS II in this way, the overall volume becomes large, and there are problems in that the cost of the device increases and the operation becomes complicated. there were.

[Object and Structure of the Invention] An object of the present invention is to provide a magnetic card reader and an interface having a single structure that can be used commonly for different types of magnetic cards. To this end, the present invention provides a magnetic card reading device with a CPU processing function to perform interface control, and includes a means for reading recorded data for any magnetic card having a plurality of different data recording formats; processing means for converting the read data into one predetermined data recording format among the plurality of different data recording formats, and a single data recording format regardless of the data recording format of the magnetic card. It is characterized by outputting data in .

[Embodiments of the invention]

The details of the present invention will be explained below based on two examples.

This is a magnetic head that reads an I8I) magnetic stripe.

When using the device, the magnetic card 9 is inserted into one end of the card guide groove 8 and then manually moved to the other end. At this time, the recording of magnetic stripes provided on one or both sides of the magnetic card 9, depending on the format of the magnetic card 9, is read by the magnetic heads 10 and 11, respectively. The signals output from the magnetic heads 10.11 are sent to the interface control circuit shown in FIG.

In FIG. 3, 10 is a magnetic head for JIS1, 11

14 is a CPU, and 15 to 17 are NAND gates.

In addition, R and CP are pulses for data sampling, RDD is read data, Cl3 is a card insertion signal, and JIS1 [input signal] is JIS1 (second track).
The input signal, out, represents an interface-controlled output signal. In this example, JIS i

Only the tracks are read.The JI81 and JIS I signal analyzers 12 and 13 each have a magnetic head 10.
Analyze the signal waveform from 11, shape the waveform, and perform RCP
, RDD, and Cl3 are generated and output.

Signals -RC, RDD(A), and 11- are directly connected to RCPout, RDDOuf, and Cl3 out through NAND gates 15, 16, and 17, respectively. On the other hand, the signals RCP's), 几DD但), CI, 8's)

If there is Cl3(5), the timing is delayed for a predetermined period so as not to overlap with this, and the NAND gate out,
Cl3 out and naru.

FIG. 4 is a signal input/output timing chart for a card that uses both JIS 1 and JIS I image formats, that is, a magnetic card that has magnetic stripes on both sides of the card. In the figure, RCPout and 'RDDOut are shown &J, +I1. '

JIS If format signal (even if A does not exist, JIS I format signal RDD as in the case of Figure 4)
data format is converted to JI81 format. Next, the data format conversion process performed by the CPU 14 will be described.

FIG. 7(a) shows the format of the original data recorded on the second track of the JIS I format card, and FIG. 7(b) shows the format of the original data recorded on the JI8■ format card. Figure 7 (C)
is the JIS I in the same figure (a) converted to JIS 1 format.
Format 2nd track shows original data.

The main items of the conversion process are as follows.

■ Converts 5-bit/character (CH) data in JIS ■ format to 8-bit/character (CH) data in JIS 1[ format.

■ Match the start code and end code to the JI8n format.

In the converted result, JIS II converted to JIS
Since the formats of the second track data and the original JI81 data are partially different, the two must be distinguishable, and in order to be able to restore the original data on the PO8 main unit, the JISI second track data must be It is desirable to leave the starting code to LR and C.

Therefore, as shown in the upper part of FIG. 7(C), a start code X'FF' and two identification codes X'B are placed at the beginning of the converted JIS I second track original data in the lower part.
B', X' B B' are added, and finally a termination code X'FF' and LRC are added. Further, the converted JIS I second track original data in the lower row includes from the start code to the LRC.

In this way, the second track original data in JI8I format is converted to data in JI81 format and sent to the PO8 main unit, so it is sufficient to prepare only the JIS1 [format] interface. Become.

FIG. 8 is a modification of the embodiment circuit shown in FIG.
JIS1 [and JI8i image format signals are both CP]
The signal is taken into U14 and then outputted, and the output signal is the same as that of the embodiment circuit shown in FIG.

Figure 9 shows another embodiment of the present invention, in which original data in JI8I format is imported for each of three tracks, and the data selected according to instructions from the POS main unit is converted and output. shows a magnetic card reader. In the figure, reference numeral 18 denotes a selector for selecting a predetermined data area, which stores output signals from a multi-track magnetic head (not shown) that reads each of the three tracks of a JISI format magnetic stripe.

The CPU 14 of the magnetic card reader 7 determines the data area to be read from the buffer 18 according to instructions from the CPU 6 of the POS main unit 3, controls the selector 19,
Necessary data is extracted, the data format is converted in the same manner as in the embodiment described above, and the data is output to the PO8 main unit 3 as JISI format data.

There are three types of data formats in the first track of the JIS I format: Forms A, B, and C.
It is as shown in Figure (a) s (b) # +c+.

The data format of the second track is already shown in Figure 7 (σ
) is shown. The third track is the same as format C shown in FIG. 10 (cl) when using an 8-bit code.

For example, in the embodiment shown in FIG. 9, the recitation number is recorded on the first track, the account number is recorded on the second track, and the name of the owner is recorded on the third track. It is optional if necessary.

〔Effect of the invention〕

As described above, according to the present invention, any format of magnetic card can be read by a single magnetic card reading device with a simple configuration. Because you can use
It is easy to operate and costs can be reduced.
