DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention reads the format information of a start-up card on which format information comprising fixed data that cannot be rewritten and a variable data recording area that can be freely input is read, so that the fixed data matches. The present invention relates to a magnetic card encoder capable of setting a variable mode of a magnetic card to a rewritable write mode.

[0002]

2. Description of the Related Art Magnetic cards are widely used for financial cards such as credit cards and cash cards, company ID cards, student ID cards, sports club membership ID cards, and the like. When issuing such a magnetic card, in order to eliminate the trouble of inputting the same data every time the magnetic card is issued, the present applicant uses a fixed data that cannot be rewritten and a variable data recording area that can be freely rewritten. A magnetic card encoder using a start-up card on which format information is recorded has been proposed (JP-A-61-39268).

[0003] When starting up the apparatus, format information of a start-up card is stored in advance, variable data different for each card is input to a portion of a variable data recording area from a keyboard or the like, and the variable data and fixed data are input. Is written on the magnetic card, thereby reducing the trouble of inputting the same data.

[0004] Therefore, for example, when a magnetic card is used as a point ticket for a membership club or as a service card for a department store, the start-up card is common to all cards such as sports club names and department store names. The format information F is read using fixed data composed of data to be recorded and format information F composed of a freely inputtable variable data recording area, and the address of the user is stored in the variable data recording area of the magnetic card. , Name, date of birth, telephone number, etc. Then, when a user who has a magnetic card enters a sports club, the points recorded in the variable data recording area are reduced according to the number of uses, or when shopping at a department store, the purchase price is It is rewritten to increase the score accordingly.

[0005]

However, the frequency of rewriting such point data is higher than the frequency of issuing a new card, and when rewriting points, the cursor usually moves to the left end of the variable data. Therefore, the cursor must be rewritten after adjusting the cursor to the number of leading digits of the recorded data. If the cursor position is input incorrectly, there is a possibility that other variable data may be rewritten. If the recording position of the score is determined in advance, it is possible to create a program that positions the cursor at the beginning of the recording position, but the data recording position of the score can be determined by each sports club or magnetic club that issues a magnetic card. Not only does it differ from department store, but also within a sports club or department store, it may differ depending on the facility or sales floor, and each time a dedicated machine with a different program must be used, increasing costs. There is. Thus, the present invention provides a method for rewriting a cursor to rewrite specific data of a magnetic card on which the same individual data as that of the start-up card is recorded without changing the program by one device. It is an object of the present invention to make it possible to easily rewrite only data at the first digit without performing unnecessary cursor operation.

[0006]

In order to solve this problem, a magnetic card encoder according to the present invention, as shown in the basic configuration diagram of FIG. 1, records non-rewritable fixed data and freely inputtable variable data. A magnetic card encoder capable of setting the variable data of a magnetic card (C) having the same fixed data to a rewritable write mode by reading the format information of a start-up card (SC) in which format information comprising an area is recorded. In the start-up card (SC), the number of leading digits of specific data to be rewritten among data recorded in the variable data recording area is recorded as digit number data (DT), and the start-up card (SC) Reading means (a) for reading the digit number data (DT) when a
And a cursor control means (c) for positioning the cursor of the display device (b) at the digit based on the digit number data (DT) when the writing mode is set.

[0007]

According to the present invention, the start-up card has the number of leading digits of specific data to be rewritten among the data recorded in the variable data recording area recorded as digit number data. When the start-up card is inserted into the device, the digit number data is read by the reading means (a). Then, when the writing mode is set, the cursor of the display device (c) is positioned at that digit by the cursor control means (c) based on the digit number data. Then, when new data is input from the input means (d) such as a keyboard, for example, the cursor is not operated, and
New data is input to the specific data portion to be rewritten. Then, the specific data before rewriting recorded on the magnetic card is rewritten by the writing means (e) to new data. Further, since the digit number data (DT) designating the cursor position is supplied from the start-up card, even when specific data having different recording positions are recorded at a plurality of positions, the digit number data (DT) is not changed. By preparing different start-up cards, the cursor can be adjusted to different recording positions with one device without changing the program.

And a magnetic head 8 slidably in contact with the magnetic stripe 7 for writing / reading desired data.

The start-up card SC used in the present invention has, on its magnetic stripe 3, for example, as shown in FIG. 3A, non-rewritable fixed data in the second to 70th digits of the data recording area. Format information F including a DP and a freely rewritable variable data recording area DV is recorded, and the first and 71st digits are initial codes which also serve as identification codes for identifying the start-up card SC. AC ₁ and end code AC ₂ (for example, “＄
EE ”and“ $ FF ”are recorded. And 7
73 after the horizontal redundancy code LRC recorded in the second digit
In the digit, the number of leading digits (for example, “67”) of the specific data DK to be rewritten is recorded as digit number data DT.

On the other hand, as shown in FIG. 4, the magnetic card encoder is provided with a control device 10 comprising a microcomputer having an interface circuit 11, an arithmetic processing device 12, and a storage device 13. A keyboard 2 and a key switch 4 are connected to the input side of the interface circuit 11 and a read signal from the magnetic head 8 is input to the interface circuit 11. Motor 14 and magnetic head 8 of card transport mechanism 9
And an external printer 16 and the like. The arithmetic processing unit 12 performs a predetermined arithmetic processing based on the magnetic recording data read when the startup card SC is inserted and the key input data, and records the format information F and the input data. Then, a writing process for writing the data on the magnetic stripe 7 of the magnetic card C is executed, or a reading process for the written data is executed.

Further, when executing the writing process, the initial position of the cursor displayed on the liquid crystal display panel is adjusted to the number of digits based on the digit number data DT recorded on the startup card SC. I have. Storage device 13
Together with stores a predetermined code matching the first code AC ₁ and the end code AC ₂ startup card SC, a program necessary for processing, storing and necessary processing data and the calculation result Remember temporarily.

Hereinafter, the processing procedure of the arithmetic processing unit 12 will be described with reference to the flowchart shown in FIG. When the key switch 4 is turned on, the apparatus is started up and the execution of the arithmetic processing shown in FIG. 5 is started. Then, in step (1), a reading process of the startup card SC is performed.
When C ₁ and the end code AC ₂ is collated, the process goes to step (2), the format information recorded on the card SC F and digits data DT is stored in a predetermined storage area of the storage device 13 You.

Next, the process proceeds to step (3) to perform a reading process of the magnetic card C whose data is to be rewritten. At this time, among the data of the magnetic card C, if the data corresponding to the fixed data DP of the format information F coincide with each other, the magnetic recording data is stored in a predetermined storage area of the storage device, and then the process proceeds to step (4). The mode is shifted to the write mode.

Then, when the process proceeds to step (5),
The variable data recorded in the portion corresponding to the variable data recording area DV of the format information F is displayed on the liquid crystal display panel 3, and at the same time, the digit number data DT input from the start-up card SC is read, and the cursor is moved. The position is aligned with the head of the data DK to be rewritten, and the process proceeds to step (6). In step (6), if data is input from the keyboard 2 or the like, the cursor is located at the first digit of the data DK, and is rewritten with new data, and the new data is stored in a predetermined storage area of the storage device 13. Is done. At this time, if the cursor is moved to a predetermined position of the variable data other than the data DK, the other variable data can be freely rewritten.

Finally, the process proceeds to step (7), in which the magnetic card C is inserted into the card insertion section 5 to obtain the new data DK input in step (6).
And other variable data and fixed data DP, together with written in the magnetic stripe of the magnetic card C, the startup card preparative early code AC ₁ and the end code AC ₂ of the SC code BC ₂ is written differs beginning code BC ₁ and the end , The magnetic card C before rewriting shown in FIG.
Is rewritten only in the specific data DK as shown in FIG.

As described above, when rewriting data,
Since the cursor is located at the first digit of the specific data, there is no need to perform a cursor operation at all, and it is possible to reduce the trouble of inputting and prevent an erroneous operation. Further, since the digit number data is supplied by the start-up card SC, even if the recording position of the specific data to be rewritten differs depending on the place of use or the user, the program can be prepared simply by preparing each start-up card. The cursor can be adjusted to each required position with one device without changing the cursor.

FIG. 6 is a flowchart showing another embodiment.
FIGS. 7A and 7B are explanatory diagrams showing magnetic recording data of a start-up card and a magnetic card used therein. In this example, various controls are performed in addition to controlling the cursor position. The data storage area between the beginning of the code AC ₁ and the end code AC ₂ startup card SC, as shown in FIG. 7 (a), together with the fixed data DP is recorded, the variable stator recording region D
V is formed of various control characters.

In this case, for example, "%" is a character indicating a variable data recording area in which usable characters can be freely written, and "@" is masked when a magnetic card is read and its contents are displayed. Character indicating the area,
“*” Is a character indicating an area in which only numerical data can be recorded, “#” is a character indicating a numerical recording area for performing a digit check, and “｛” or “｝” is a character for setting a position and a method as a result of the digit check. . For example, “｛” records the last digit of the numerical data in the numerical recording area where the digit check is to be performed by doubling the odd digits and adding the even digits, and “｝” is doubling the even digits. The last digit of the sum of the one and the odd digit is recorded.

Further, "!" Indicates that the variable data recorded using another startup card having the same fixed data DP is erroneously erased or freely rewritten, and the card on which the data is recorded cannot be freely issued. This is a character for setting an area in which a part of the variable data cannot be rewritten or displayed. Then, a portion where numbers, alphabets, kana and other characters other than those described above are recorded is treated as fixed data DP.

The format information F is, for example, 2 characters in accordance with the maximum number of characters defined in JIS.
Data is recorded in the first to 70th digits, and thereafter, data necessary for processing the program of the magnetic card encoder is recorded. For example, in the 71st to 76th digits, control data for disabling a specific routine of the program and limiting functions according to the responsibility of the operator is recorded.

The 71st digit restricts the display function.
When "0", the fixed data is displayed, and when "1", the fixed data is masked and displayed. The 72nd digit restricts the reading mode. When it is "0", the reading mode can be set. When it is "1", the reading mode cannot be set. For example, writing only for issuing a new card Machine is set. The 73rd digit restricts the writing mode.
When it is "0", it is set as a read-only machine, and when it is "1", it shifts to the write mode after the end of the read mode. The 74th digit restricts the function of the write button (not shown).
When the value is "0", the write mode can be set by pressing the write button. When the value is "1", the write button is invalidated, and the issuance of a new card becomes impossible. The 75th digit restricts the confirmation reading process for confirming the recorded contents of the card before performing the writing process in the writing mode. When the value is "0", the confirmation reading process is not performed. When the confirmation reading process is performed.
The 76th digit controls the release of the write mode, and is "0"
In the case of, the writing mode is not released and continuous writing is possible, and in the case of "1", the writing mode is released and returns to the reading mode.

In the 77th and 78th digits, a security code recorded after the horizontal redundancy code LRC of the magnetic card C to be issued is recorded, and in the 79th digit, the security code is recorded on the magnetic card C to be issued. The number of digits indicating the position of the horizontal redundant code is recorded, and the record length is selected according to the data amount of the format information F. In the 80th digit, the start position of the specific data DK to be rewritten (for example, “6
1)) is recorded and used as initial position setting data when controlling the cursor. Further, the upper digit of the data area for recording the serial number is recorded in the 81st digit, and the lower digit of the data area for recording the serial number is recorded in the 82nd digit. Then, 83 digit and 84 digit at the end code AC ₂ and longitudinal redundancy code LRC is recorded.

The processing procedure of the arithmetic processing unit 12 when issuing a magnetic card C using such a startup card SC or rewriting data of the issued magnetic card C will be described with reference to the flowchart shown in FIG. . When the key switch 4 is turned on, the arithmetic processing shown in FIG. 6 is started. First, when the start-up card SC is inserted in step (1), the process proceeds to step (2). The process moves to (3).

In step (2), the magnetic recording data recorded on the magnetic stripe 7 of the start-up card SC is read, and in step (4), the read initial code AC ₁ and end code AC ₂ are read. By comparing the card with the code stored in the device, it is determined whether or not the card is the startup card SC. When it is determined that the card is not the startup card SC, the process proceeds to step (5), an error display and an alarm sound are issued, and the process returns to step (1). When it is determined that the card is the startup card SC, step (6) is performed. Then, the read format information F and other data are displayed for about 1 second, and then the storage device 1 such as an electric erasable ROM is displayed.
3 and the process proceeds to step (7).

On the other hand, if a password is input in step (1), the process proceeds to step (3) to check whether the password matches a previously stored password. ), An error display and an alarm sound are emitted, and the process returns to step (1). If the values match, the process goes to step (9) to reduce the format information F and other data of the start-up card SC that was previously input. After displaying for one second, the process proceeds to step (7).

In step (7), the data in the 72nd digit of the start-up card SC is referred to. If the value is "0", the flow shifts to step (10) to set the apparatus to the reading mode and the reading mode. Then, the monitor lamp for displaying the fact is turned on, and when it is "1", the process goes to step (11) to display the format information F, and then goes to step (12) to set the apparatus to the write mode and A monitor lamp for indicating that the mode is the writing mode is turned on. In step (11), the format information F
Is displayed, the data in the 71st digit of the start-up card SC is referred to. When the value is "0", the fixed data DP is displayed in a hidden character, and when it is "1", the fixed data DP is displayed as it is.

When the reading mode is set in step (10), the process proceeds to step (13) to determine whether or not the write button of the keyboard 3 has been pressed. When the button is pressed, the process proceeds to step (11) via step (14). In this step (14), the data in the 74th digit of the startup card SC is referred to. If the value is "0", the process proceeds to step (11), and writing is possible. If the value is "1", the process proceeds to step (10). And the write button is disabled.

Next, if the write button is not depressed in the step (13), the flow shifts to the step (15) and waits until the magnetic card C is inserted. If the magnetic card C is inserted, the process proceeds to the step (16). Magnetic recording data is read,
In step (17), it is checked against the format information F of the startup card SC. This collation is performed, for example, by checking whether the fixed data DP matches or not, by checking the variable data recording area DV.
Each control character "%""*""#""｛""
This is performed by checking whether data corresponding to “｝” or the like is recorded.

If it does not match the format information F, the process proceeds to step (18), where an error message and an alarm sound are emitted, and the process returns to step (15).
If they match, the process proceeds to step (19) where the read magnetic recording data is displayed. At this time, when the 71st digit of the startup card SC is “1”, the fixed data DP is masked, and the portion where “さ れ” and “!” Are recorded in the variable data recording area DV of the format information F is also included. Masked. Next, the process proceeds to step (20), where the 73rd digit data of the startup card SC is referred to. If the value is "0", the process returns to step (15) to be used as a write-only machine, and if the value is "1". Goes to step (12) and is set to the write mode.

When the writing mode is set in step (12), the monitor lamp is turned on, and the process proceeds to step (21) to perform cursor control. This cursor control refers to the digit number data DT recorded at the 80th digit of the startup card SC, and moves the cursor to the variable data recording area D.
Match the number of digits, not the left end of V. Therefore,
If the number-of-digits data of the cursor is recorded in accordance with the position of the update data, the cursor initial position is always set at the beginning.

Then, the process proceeds to a step (22) to input desired variable data from the keyboard. At this time,
Each control character "%" in the variable data recording area DV
If data other than the data corresponding to “*”, “#”, etc. is input, an error message and an alarm sound are emitted. Also, if there is a digit check "#",
Numerical data of the digits represented by “｛” and “｝” are automatically calculated and input based on the numerical data written in the “#” portion without inputting from the keyboard 3.

Further, the startup card SC 81
When predetermined numerical data is input to the continuous number recording area defined by the digits and the 82nd digit, the serial numbers are automatically added one by one when performing a continuous writing process described later. Upon completion of the input, the flow shifts to step (23) where the data in the 75th digit of the startup card SC is referred to, and
If it is "0", the process proceeds to step (29) without performing the confirmation reading process, and if it is "1", it proceeds to step (24).
And the confirmation reading process is performed.

In the confirmation reading process, it is determined whether or not the data has been written to the card C on which the data is to be written in accordance with the format information F so that the magnetic card cannot be copied without permission based on the rewritten data. In step (24), the process waits until the magnetic card C is inserted. When the magnetic card C is inserted, the process goes to step (25) to read the magnetic recording data, and goes to step (26) where the fixed data DP matches. Then, it is determined whether or not data corresponding to the control character in the variable data recording area DV is recorded.

At this time, in order to make a more precise determination, it may be determined whether or not all the magnetic recording data matches the data read in step (16). If they do not match, step (27)
Then, an error message and an alarm sound are issued, and the process returns to step (24). If they match, the process proceeds to step (28), where the read magnetic recording data is displayed for several seconds, and then the rewritten data is displayed. Be done. In addition,
In this case, as in step (19), a predetermined portion is masked based on the data recorded on the startup card SC.

Then, the process proceeds to a step (29), wherein
The magnetic card C is reciprocated in the card insertion section 6, and the writing process is performed in step (30). The writing process, as shown in FIG. 7 (b), 1 digit initially code BD ₁
Is recorded from the second digit, the fixed data DP and the rewritten variable data are recorded, and the last digit data (the 72nd digit in this example) recorded at the 79th digit of the startup card SC is a horizontal redundant code LRC, one. record the code BD ₂ end before digit (column 71), is further recorded security code after the horizontal redundancy code LRC.

In this case, first, the code BD₁And end sign
BD_TwoIs, for example, "@EE" or "@EE".
Initial code AD of the card SC₁And end sign
AD _TwoA magnetic card with a code different from that recorded and issued
To use as a startup card SC
ing.

Then, the process proceeds to step (31), where the magnetic recording data of the magnetic card C to which the data has been written in step (30) is read again, and the written data is compared with the read data. Emits an error message and an alarm sound, and if they match, goes to step (32) to display the data and end the writing process. In this case, as in step (19), a predetermined portion is masked based on the data recorded on the startup card SC.

Next, the process proceeds to step (33), where it is determined whether or not to perform the continuous writing process based on the data in the 76th digit of the startup card SC. In this case, the process proceeds to step (34), and if there is a continuous number recording area, 1 is added to the numerical data.
Is added, and the process returns to step (12). If "1" is recorded, the process returns to step (7).

According to the present embodiment, first, the start-up card SC is read and the magnetic recording data such as the format information F is stored (steps (1) to (6)). When a new card is issued, a write mode is set by pressing a write button (step (1)).
2)). At this time, the position of the cursor is not at the head of the variable data, but is initialized to the position of the digit number data DT recorded at the 80th digit of the startup card SC (step (21)). Move to
The user inputs personal data such as a name and a password (steps (21) to (22)).

When a new card is issued, the confirmation reading process (steps (23) to (28)) is not required. Therefore, in order to avoid this, "0" is placed in the 75th digit of the startup card SC. Is recorded, the writing process is performed without performing the confirmation reading (steps (29) to (32)).

If only card reading processing is performed at the reception of a membership club, etc., the startup card SC
If "0" is recorded in the 72nd digit, "0" is recorded in the 73rd digit _, and "1" is recorded in _the 74th digit, the writing process is prohibited. When this startup card SC is used, it becomes a read-only machine that performs only the reading process (steps (15) to (20)).
Since only the magnetic card C that matches the fixed data of C can be read, there is no risk of misuse.

In addition to the card reading process, for example, in the case where a score is recorded as data on the magnetic card C, the score is rewritten each time the card is used. If "1" is recorded in the digit and the writing process can be performed after the reading process is completed, and the digit number data DT of the leading digit for recording the score is recorded in the 80th digit, the writing mode is set. When this happens, the cursor is positioned at the head of the data to be rewritten, so that the trouble of moving the cursor can be saved. When it is necessary to rewrite other variable data, the cursor may be moved to write desired data.

Further, a student card or a member number is written in a data area of a credit card which is issued by a credit card company and a joint card for giving a credit card function to a student card or another member card is issued. If so, as a startup card SC,
As shown in FIG. 7A, the fixed data DP common to the credit card is recorded, and “!” Is recorded in the variable data portion recorded on the credit card, so that the startup card cannot be rewritten and cannot be read. It is made impossible, and the data in which "%" or "*" is recorded in the part where the student number or the like is input as the specific data DK is used.

In addition, the 80th of the startup card SC
The first digit of the position where the student number or the like is recorded in the digit is recorded as digit number data DT, and the upper and lower digits of the student number recording area recorded as the serial number in the 81st and 82nd digits The number of digits is recorded, and “1” is recorded in the 72nd digit so that it can be used as a write-only device for the additional recording portion.
"1" is recorded in the digit, so that confirmation reading is performed, and "0" is recorded in the 76th digit, so that continuous writing can be performed.

Then, when the startup card SC is inserted, the 72nd digit is "1", so that the apparatus is set to the write mode (step (12)). Then
Since the cursor is set at the head position of the student number recording area, the first student number is input without moving the cursor as it is (step (22)). A magnetic card C serving as a credit card is inserted in the order of student numbers.

The magnetic card C is firstly read for confirmation.
It is determined whether or not the fixed data DP matches the fixed data of the startup card SC.
As shown in FIG. 7B, the currently read fixed data DP and variable data and the previously input student number are written on the magnetic stripe 7 of the magnetic card C (steps (23) to (32)). . When the students are inserted one after another in the order of the student numbers, the student numbers are added one by one as a continuous number (step (34)). The number is recorded, and a large number of joint cards can be issued in a short time.

[0047]

As described above, according to the present invention, when the apparatus is set in the writing mode, the cursor of the display device is not positioned at the left end of the variable data and the specific data to be rewritten is not changed. Since the position can be set to the first digit of the data, it is possible to easily rewrite the necessary parts without troublesome cursor movement and mistakes in the input position, and the cursor position is the digit recorded on the startup card. Since it is set based on numerical data, even if the recording position of the specific data to be rewritten differs depending on the place of use or the user, each start-up according to the recording position of the specific data to be rewritten By preparing the card, you can move the cursor to each required position with one device without having to change the program. It has a very excellent effect of that.
