Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a magnetic card encoder for writing recorded information onto a magnetic card having a magnetic recording section.

[Prior art and its problems]

Magnetic cards are generally used for ID cards, time cards, room entry control cards, etc. Recorded information such as company name, personal name, registration number, etc. recorded in the magnetic recording part of the magnetic card can be read using a magnetic card reader. By reading the data, predetermined data processing is performed.

By the way, when issuing a new magnetic card, a magnetic card encoder is used to write recorded information into the magnetic recording section of an unused magnetic card, but what if anyone could operate the magnetic card encoder? There is a great concern that magnetic cards may be forged or copied without permission.

In addition, we manage and forge products so that only specific people can operate them.
Even in the case of preventing duplication, etc., it is extremely troublesome to input all of the recorded information one by one, and there is a new problem in that it increases the number of erroneous operations.

Therefore, in the conventional magnetic card encoder, it does not operate unless the rD card dedicated to the operator is inserted, and fixed data A that does not actually require rewriting is read in advance from among the recorded information Kl shown in Fig. 5. Generally, only the variable data B', which is stored in the only memory and requires input of different data for each card, such as the registration number, is entered using a keyboard.

However, in such conventional magnetic card encoders, fixed data is stored in read-only memory in advance, so it is impossible to change the fixed data once written. In order to store the rotation data, the storage capacity of the memory must be increased, which poses a problem of increasing costs.

In order to solve this problem, the applicant did not store fixed data in a read-only memory, but recorded it on a separate master magnetic card, and by preparing multiple types of master magnetic cards, the applicant increased the memory capacity. proposed a magnetic card encoder that made it possible to change fixed data without increasing data (see Japanese Patent Application No. 152,111/1982).

However, the content recorded on a newly issued card by this magnetic card encoder is no different from the content recorded on the master magnetic card except for variable data, so you can use the magnetic card without using the master magnetic card. By using this, it becomes possible to duplicate the same card.

Therefore, in order to completely prevent forgery and duplication, it is inconvenient that at least two aim cards, the master magnetic card and the operator-dedicated TD card, must be managed.

[Purpose of the invention]

Therefore, the present invention makes it possible to prevent copying and counterfeiting of magnetic cards by providing a master magnetic card on which fixed data is recorded with the function of an ID card for exclusive use of the operator, and also makes it possible to easily change the fixed data. The purpose is to provide a magnetic force decoder that can be used.

[Structure of the invention]

In order to achieve this object, the present invention provides a magnetic card encoder that writes recorded information on a magnetic card having a magnetic recording section, in which fixed data that cannot be rewritten and a variable data recording area that can be input freely are formatted. A master magnetic card on which a predetermined encryption code is recorded for recording information and determining whether the magnetic card is a master magnetic card, and a reading means for reading the format information and encryption code of the master magnetic card. a determining means for determining whether or not the encrypted code read by the reading means matches a predetermined code; a storage means for storing the format information when the determining means determines that the code matches the predetermined code; It is characterized by comprising an input section for inputting desired data into a variable data recording area of format information stored in a storage means, and a writing means for writing the data input from the input section and the fixed data onto a magnetic card. do.

[Action of the invention]

According to the present invention, writing to a new card can be performed only when the encryption code recorded on the master magnetic card matches a predetermined code, so that the master magnetic card must be used. In this case, a new card cannot be issued, and since the encryption code is not written on the new card, the magnetic card encoder cannot be operated with the new card.

In addition, since fixed data that cannot be rewritten is recorded on the master magnetic card, by preparing multiple types of master magnetic cards, it is possible to easily change a large amount of fixed data without increasing the memory storage capacity. .

When the magnetic card 6 is inserted, the process moves to step (4) to read the data recorded in the magnetic recording section 6a of the magnetic card 6 and temporarily store it in the buffer memory in the storage device 10. Proceeding to step (5), it is determined whether the encryption code D recorded in the predetermined area of the data matches a predetermined code stored in advance.

Then, if the encryption code D does not match the predetermined code, that is, if it is determined that the magnetic card 6 is not the master magnetic card 6M, step.

The process moves to step (6), displays an error on the character display section 3, erases the contents of the buffer memory, and then proceeds to step +2.
Return to 1.

Further, in step (5), if the encryption code D matches the predetermined code, that is, if it is determined that the magnetic card 6 is the master magnetic card 6M, the process moves to step (7) and the data is stored in the buffer memory. Among the stored contents, only the formant information [1] is stored in a predetermined storage area of the memory bag W10, and after proceeding to step (8) and displaying the format information FT for a predetermined period of time (for example, 1 second), rc indicating completion of registration of format report F1 in step (9).

Display the message such as piedJ and step (10)

At this time, the format information FI is fixed to the recording device 10, so unless the key switch 4 is turned off, the format information FI will not be changed even if another master magnetic card is inserted. There isn't.

In step (10), the drive circuit 12 is connected to the magnetic head 5.
It is determined whether the write switch 2C for switching to a write mode in which recording information is written from b is pressed.

If the write switch 2C is pressed, the process proceeds to step (11), where the drive circuit 12 is switched to the write mode, and the process proceeds to step (12), where the format information FI stored in the storage device 10 is The storage contents of the buffer memory corresponding to the variable data storage area therein are displayed on the character display section 3, and predetermined cursor control is performed to move the cursor position to the beginning position of the variable data storage area.

Next, the process proceeds to step (13), in which variable data based on key input from the keyboard 2 is sequentially stored in the buffer memory in the storage device 10 and displayed on the character display section 3.

Next, the process moves to step (14), and it is determined whether input from the keyboard 2 has been completed. In this case, the determination is made based on whether or not a predetermined write completion key indicating that the input of variable data has been completed is pressed. If it is not pressed, the system waits until it is pressed, and when it is pressed, the The storage contents of the buffer memory are stored in a predetermined storage area of the storage device 10, and the process moves to step (15).

In this step (15), it is determined whether or not an unused magnetic card 6N has been inserted. If the magnetic card 6N is not inserted, the process waits until it is inserted, and when it is inserted, the process moves to step (16).

In this step (16), fixed data A and variable data are written into the unused magnetic card 6N, and the process moves to step (17).

In step (17), a confirmation mode is set to confirm the written information written in step (16), and the drive circuit 12 of the magnetic head 5b is switched to the continuous output side.

Next, proceed to step (18) and insert the magnetic card 6N.
After displaying on the character display section 3 a re-insertion instruction (for example, the characters r6=VerifyJ) for reinserting the card into the magnetic card insertion section 5, the process moves to step (19).

In this step (19), similarly to step (15), it is determined whether or not the magnetic card 6N is inserted into the magnetic card insertion part 5. If the magnetic card 6N is in the non-loading state, the magnetic card 6N is inserted. When the magnetic card 6N is inserted, the process moves to step (20).

In this step (20), the write information written on the magnetic card 6N is read out via the magnetic head 5b and stored in the temporary buffer memory, and the storage device 10
The format information and the recorded information consisting of the variable data stored in the memory are called and compared and verified to determine whether or not they match.

At this time, if the two match, the process moves to step (22), and if they do not match, the process moves to step (23).

In step (22), the written information (=continuation information) is displayed as is on the character display section 3, and a check display (for example, the characters "0=CheckJ") is displayed, and the process proceeds to step (24), where the key is pressed. It is determined whether the switch 4 continues to be in the on state, and if it is in the off state, the process moves to step (10) to issue a new magnetic card 6, and if it is in the off state, the process ends.

In addition, in step (23), in addition to displaying the check, a specific symbol (for example, "?" or a shaded area indicates "mouth") is displayed on the character display section 3 to indicate where the recorded information and the corresponding written information do not match. At the same time, emit an error sound consisting of continuous sounds such as "bi-hepi-hepino" and then step (
24).

Note that if the write switch 1° is not pressed in step (10), the process moves to step (25) and waits until the magnetic card 6 is inserted.

Then, when the magnetic card 6 is inserted, step (
26), reads the recorded information KI recorded in the magnetic recording section 6a of the magnetic card 6, and stores it in the storage device 10.
The data is temporarily stored in the internal buffer memory and the process moves to step (27).

In this step (27), the recorded information Kl stored in the step (26) and the formant information FT stored in the step (7) are compared, and if the fixed data A of both coincide, the step ( 28) to display the recorded information KI on the character display section 3, and then return to step (10). If they do not match, step (28) is executed.
Step 9) displays an error message and erases the contents of the buffer memory, and then returns to step (10).

Here, the processing of steps (11 to (4)) is a specific example of the reading means, the processing of step (5) is a specific example of the determining means, the processing of steps (7) to (9) is a specific example of the storage device, and the processing of step ( Processes 10) to (16) are specific examples of the writing means.

The above is an example of the configuration of the present invention, and the operation thereof will be explained next.

First, by turning on the key switch 4, the arithmetic processing unit 9 of the control device 7 starts executing the process shown in FIG. , Master magnetic card insertion instruction r In5ert 5 tartup card
! J is displayed (Step (21) - In this state, if the desired master magnetic card 6M is selected and inserted into the magnetic card insertion part 5, the process moves from Step (3) to Step (4). The format information Fl and the encryption code D recorded in the magnetic recording section 6a of the master magnetic card 6M are read via the magnetic head 5b, and are temporarily stored in the buffer memory.

Next, proceed to step (5) and insert the master magnetic card 6.
It is determined whether the encryption code D, which also serves as the start code and the end code of the data recorded in M, matches the codes r$F, El, and r$FFJ stored in advance in the storage device 10.

If they match, the process moves to step (7), where only the format information FI stored in the buffer memory is stored in a predetermined storage area of the storage device IO, and step (8)
) and displays the format information FI for, for example, one second, and then moves to step (9) to display the characters rcopiedJ on the character display section 3 indicating completion of format information registration.

Next, the process moves to step (10), and the write switch 2c is turned on.
It is determined whether or not has been pressed, and if it has been pressed, the process moves to step (11) to switch the drive circuit 12 to write mode, and the process moves to step (12) to write the formant stored in the storage device 10. Fixed data A of information F■ is "-
'' and the contents of the buffer memory corresponding to the variable data recording area are displayed on the character display section 3, and the cursor is moved to the beginning of the variable data recording area.

At this time, nothing is stored in the variable data storage area of the buffer memory, so for example, only that part is
"Rorororo" is displayed.

In this state, when desired variable data is input using the keyboard 2, the input data is temporarily stored in the buffer memory and displayed on the character display section 3 (step (13)).

Thereafter, by pressing a predetermined key input completion key, the contents of the buffer memory are stored in a predetermined storage area of the storage device 10 (step (14)), and step (1)
Move on to 5).

Here, insert an unused magnetic card 6N into the magnetic card insertion part 5.
Step (15) to Step (16)
As shown in FIG.
A magnetic head 5b is attached to the magnetic recording section 6a of the magnetic card as l.
At the same time, the initial code r$EEJ and the ending code [$
A code D' (for example, r$EEJ and r$EEJ) different from FFJ is written and the write process is completed.

When the writing process is completed, the process moves to step (17), where the confirmation mode (continuous output mode) is set, and the drive circuit 12 of the magnetic field 5b is switched to the continuous output side, and then the process moves to step (18). , a magnetic card 6 insertion instruction r6=VerifyJ is displayed on the character display section 3.

/ In this state, when the magnetic card 6 is inserted into the magnetic card insertion part 5 again, the process moves from step (I9) to step (20), and the written ↑ information in the magnetic recording part 6a of the magnetic card 6 is read out. The read information and the step (7) and step (1) are temporarily stored in the buffer memory.
It is determined whether or not the recorded information recorded in step 6) matches (step (21)).

If the two match, the process moves to step (22), where the written report is displayed as is on the character display section 3, and a check mark "<-CheckJ" is displayed, and then, in step (24), the key switch is displayed. It is determined whether or not the Z switch 4 is in the on state, and if it continues to be in the on state, the process moves to step (10), and if it is in the off state, the process ends.

Further, if the determination result in step (21) is that the written report and the subsequent information do not match, the process moves to step (23), and the character display section 3 displays "6-Check J".
is displayed, a specific symbol is displayed at the character position corresponding to the mismatched part to clearly visually indicate that there is a mismatch, and an error sound "Bi-hepi-pi-no" is emitted to call for attention.

To correct the discrepancy here, return to step (10) and press the write switch 2C to proceed to step (12).
In step (13), the content of the buffer memory at that time, that is, the same display as in step (23), is displayed, so move the cursor to the corrected part and input the correct data again (step (13)), and then perform the writing process in the same way. Just go.

The above is the case where a new card is issued using the unused magnetic card 6N.Next, the case where the contents of a previously issued card are changed, such as when updating an expired card, will be explained.

In this case, in step (10), insert the magnetic card 6 to be updated into the magnetic card insertion part 5 without pressing the write switch 2c (step (25)).
Since the drive circuit 12 is in continuous output mode, the recording part NKI recorded in the magnetic recording part 6a of the magnetic card 6 is read and temporarily stored in the buffer memory (step (
26) ).

Then, the fixed data A of the magnetic card 6 and the step (
If the fixed data A of the master magnetic card 6M stored in step 7) matches, the contents of the buffer memory are displayed and the process returns to step (10).

In this step (10), if the write switch 2C is pressed, the contents of the buffer memory, that is, the variable data recorded on the magnetic card 6 to be updated will be displayed (step (12)), and the expiration date will be Step (13)) Move the cursor to the location that requires changes, etc., and enter the desired data.If you perform the writing process in the same way as when issuing a new card, the contents of the previously issued magnetic card 6 will be updated. can be rewritten.

In the above embodiment, the master magnetic card 6M
Although the case has been described in which the encryption code D is used as both the start code and the end code of data, the present invention is not limited to this. For example, the four digits 67 to 7o may be used as the encryption code D area.

However, if the start code and end code are used together as the encryption code D, all of the arbitrary data area can be used as the format information FM.
It has the advantage that it can be used as an area.

Further, in the embodiment, a case has been described in which the magnetic card 6 is used as an ID card, but the present invention is not limited to this. It can be used for various purposes such as issuing management cards or restaurant membership cards.

Furthermore, the magnetic card encoder can of course be used online, and can also be used as a terminal by connecting online to a host computer via an interface.

〔Effect of the invention〕

As described above, according to the present invention, writing to a new card can be performed only when the encryption code recorded on the master magnetic card matches a predetermined code. New cards cannot be issued without the use of magnetic cards, and magnetic card counterfeiting and

Detailed Description of the Invention Field of Application] The present invention relates to a magnetic card encoder for writing recorded information on a magnetic card having a magnetic recording section. [Prior art and its problems] Magnetic cards are generally used for identification cards, time cards, room access control cards, etc., and are used to store company names, individual names, registration numbers, etc. recorded in the magnetic recording section of the magnetic card. Predetermined data processing is performed by reading recorded information using a magnetic card league. By the way, when issuing a new magnetic card, a magnetic card encoder is used to write recorded information into the magnetic recording section of an unused magnetic card, but if anyone can operate the magnetic card encoder, There is a great concern that magnetic cards will be counterfeited or copied without permission. In addition, we manage and forge products so that only specific people can operate them.
? 3 [Even when preventing manufacturing, etc., it is extremely troublesome to input all of the recorded information one by one, and there are new problems such as frequent erroneous operations. Therefore, in the conventional magnetic card encoder, the operation In addition, among the recorded information Kl shown in Fig. 5, fixed data A that does not require actual rewriting is stored in a read-only memory in advance, and registration numbers, etc. Generally, only variable data B', which requires inputting different data for each card, is input using a key fob.However, with such conventional magnetic card encoders, Since fixed data is stored in read-only memory in advance, it is impossible to change the fixed data once it has been written. There was a problem in that the storage capacity had to be increased, which caused an increase in costs.In order to solve this problem, the applicant did not store fixed data in read-only memory, but instead created a separate master memory. We proposed a magnetic card encoder that enables fixed data to be changed without increasing memory capacity by recording on a magnetic card and preparing multiple types of master magnetic cards (see Japanese Patent Application No. 152,111/1982). ).However, the contents recorded on a newly issued card by this magnetic card encoder are no different from the contents recorded on the master magnetic card except for variable data, so the magnetic card encoder can record the magnetic card without using the master magnetic card. Using a card makes it possible to duplicate the same card. Therefore, in order to completely prevent forgery and duplication, it is necessary to manage at least two types of cards: a master magnetic card and an operator-specific ID card. [Objective of the Invention] Therefore, the present invention makes it possible to prevent copying and counterfeiting of magnetic cards by providing a master magnetic card on which fixed data is recorded with the function of an ID card exclusively for the operator. An object of the present invention is to provide a magnetic card encoder that can easily change fixed data. [Structure of the Invention] A magnetic card encoder for writing recorded information records non-rewritable fixed data of the recorded information and a freely inputtable variable data recording area as format information, and also determines whether or not the magnetic card is a master magnetic card. A master magnetic card on which a predetermined encryption code is recorded, a reading means for reading the formant information and the encryption code of the master magnetic card, and whether the encryption code read by the reading means matches the predetermined code. a determining means for making such a determination; a storage means for storing the format information when it is determined by the determining means that they match; and a storage means for inputting desired data into a variable data recording area of the formant information stored in the storage means. It is characterized by comprising an input section and a writing means for writing the data inputted from the input section and the fixed data onto a magnetic card. [Operation of the Invention] According to the present invention, writing to a new card can be performed only when the encryption code recorded on the master magnetic card matches a predetermined code. Since a new card cannot be issued without using the card, and the encryption code is not written on the new card, the magnetic card encoder cannot be operated by the new card. In addition, since fixed data that cannot be rewritten is recorded on the master magnetic card, by preparing multiple types of master magnetic cards, it is possible to easily change a large amount of fixed data without increasing the memory storage capacity. .

After setting the drive circuit 12 to the continuous printing mode so that b is on the continuous printing side, in step (2), for example, rInsert 5 tartup card! is displayed on the character display section 3. J
Display the master magnetic card repository instructions such as
3) and waits until the magnetic card 6 is inserted. When the magnetic card 6 is inserted, the process moves to step (4), where the data recorded in the magnetic recording section 6a of the magnetic card 6 is read and temporarily stored in the buffer memory in the storage device 1o. Next, the process moves to step (5), and it is determined whether the encryption code D recorded in the predetermined area of the data matches a predetermined code stored in advance. Then, if the encryption code D does not match the predetermined code, that is, if it is determined that the magnetic card 6 is not the master magnetic card 6M, the process moves to step f6),
After displaying an error on the character display gTS3, the contents of the buffer memory are erased and the process returns to step (2). Further, in step (5), if the encryption code D matches the predetermined code, that is, if it is determined that the magnetic card 6 is the master magnetic card 6M, the process moves to step (7) and the data is stored in the buffer memory. Among the stored contents, only the format information FI is stored in a predetermined storage area of the storage device 10, and after proceeding to step (8) and displaying the format information Fr for a predetermined period of time (for example, 1 second), step ( 9) rc indicating completion of registration of format information Fl. Display the message such as piedJ and step (10)
Move to. At this time, since the formant information FI is fixed to the storage device 10, the format information Fl will not be rewritten even if another master magnetic card is inserted, unless the key switch 4 is turned off. In step (10), the drive circuit 12 of the magnetic herad 5b
It is determined whether the write switch 2C, which sets the device to write mode, has been pressed. If the write switch 2C is pressed, the process proceeds to step (11), where the drive circuit 12 is switched to the write mode, and the process proceeds to step (12), where the format information Fl stored in the storage device 10 is The storage contents of the buffer memory corresponding to the variable data storage area therein are displayed on the character display section 3, and predetermined cursor control is performed to move the cursor position to the beginning position of the variable data storage area. Next, the process proceeds to step (13), in which variable data based on key input from the keyboard 2 is sequentially stored in the buffer memory in the storage device 10 and displayed on the character display section 3. Next, the process moves to step (14), and it is determined whether input from the keyboard 2 has been completed. In this case, the determination is made based on whether or not a predetermined write completion key indicating that the input of variable data has been completed is pressed. If it is not pressed, the system waits until it is pressed, and if it is pressed, then The storage contents of the buffer memory are stored in a predetermined storage area of the storage device 10, and the process moves to step (15). In this step (15), it is determined whether or not an unused magnetic card 6N has been inserted. If the magnetic card 6N is not inserted, the process waits until it is inserted, and when it is inserted, the process moves to step (16). In this step (16), fixed data A and variable data are written into the unused magnetic card 6N, and the process moves to step (17). In this step (17), a confirmation mode is set to confirm the written information written in the step (1B), and the drive circuit 12 of the magnetic helad 5b is switched to the continuous output side. Next, proceed to step (18) and insert the magnetic card 6N.
After displaying on the character display section 3 a re-insertion instruction (for example, the characters r6-VerifyJ) for re-inserting the magnetic card into the magnetic card insertion section 5, the process moves to step (19). In this step (19), it is determined whether or not the magnetic card 6N has been inserted into the magnetic card insertion part 5 in the same way as the steering knob (15), and when the magnetic card 6N is in a non-volatile state, the magnetic card 6N The process waits until the magnetic card 6N is inserted, and when the magnetic card 6N is inserted, the process moves to step (20). In this step (20), the write information previously written on the magnetic card 6N is read out from the magnetic card 5b, and is temporarily stored in the backup memory, before proceeding to step (21). In step (21), the format information and the recorded information consisting of variable data stored in the storage device 10 are called up, and the two are compared and verified to determine whether or not they match. At this time, if the two match, the process moves to step (22), and if they do not match, the process moves to step (23). In step (22), the written information (-read information) is displayed as is on the character display section 3, and a check mark (for example, the characters r 6 = CheckJ) is displayed, and the process proceeds to step (24), where the key is pressed. The above step (10) determines whether the switch 4 continues to be in the on state, and if it is in the on state, a new magnetic card 6 is issued.
and when it is in the off state, the process ends. In addition, in step (23), in addition to displaying the check, a specific symbol (for example, "?" or a shaded area indicates "mouth") is displayed on the character display section 3 to indicate where the recorded information and the corresponding written information do not match. For example, "pin, bottle,
After emitting an error sound consisting of a continuous sound of "ping", the process moves to step (24). In addition, steps (25) to (28) are performed in order to confirm the recorded information Kl recorded on the magnetic card 6 when rewriting some of the contents of the already issued magnetic card 6 and reissuing it. This is a loop displayed on the display unit 3. That is, if the write switch 2C is not lowered in step (10), the process moves to step (25) and waits until the magnetic card 6 is inserted. Then, when the magnetic card 6 is inserted, step (
26), reads the recorded information KI recorded in the magnetic recording section 6a of the magnetic card 6, and stores it in the storage device 10.
The data is temporarily stored in the internal buffer memory and the process moves to step (27). In this step (27), the recorded information KI stored in the step (26) and the format information Fl stored in the step (7) are compared, and if the fixed data A of both matches, the recorded information KI stored in the step (26) is compared with the format information Fl stored in the step (7). After displaying the recorded information Kl on the character display section 3, the process returns to step (10). If they do not match, step (2)
Step 9) displays an error message and erases the contents of the buffer memory, and then returns to step (10). Here, the processing of steps fl) to (4) is a specific example of the reading means, the processing of step (5) is a specific example of the determining means, the processing of steps (7) to (9) is a specific example of the storage means, The processes (10) to (16) are specific examples of the writing means. The above is an example of the configuration of the present invention, and the operation thereof will be explained next. First, by turning on the key switch 4, the arithmetic processing unit 9 of the control device 7 starts executing the process shown in FIG. At the same time, insert the master magnetic card.
! J is displayed (step (2)) - In this state, when the desired master magnetic card 6M is selected and inserted into the magnetic card insertion section 5, the process moves from step (3) to step (4). Then, the format information Fl and the encryption code D recorded in the magnetic recording section 6a of the master magnetic card 6M are read via the magnetic head 5b, and are temporarily stored in the buffer memory. Next, proceed to step (5) and insert the master magnetic card 6.
It is determined whether the encryption code D, which also serves as the start code and the end code of the data recorded in M, matches the codes r$EEJ and r$FFJ stored in advance in the storage device 10. If they match, the process moves to step (7), where only the format information FI stored in the buffer memory is stored in a predetermined storage area of the storage device 10, and step (8)
) and displays the format information FI for, for example, one second, and then moves to step (9) to display the characters rcopiedJ on the character display section 3 indicating completion of format information registration. Next, proceed to step (10) and turn on the write switch 2C.
It is determined whether or not the button has been pressed, and if it has been pressed, the process moves to step (11), the drive circuit 12 is switched to the write mode, and the process moves to step (12), where the memory is stored in the storage device 10. The fixed data A of the format information FI is
-" and the contents of the buffer memory corresponding to the variable data recording area are displayed on the character display section 3, and the cursor is moved to the beginning of the cough variable data recording area. At this time, since nothing has been stored in the variable data storage area of the buffer memory yet, only that part is displayed as "rorororo", for example. In this state, when desired variable data is input using the keyboard 2, the input data is temporarily stored in the buffer memory and displayed on the character display section 3 (step (13)). Thereafter, by pressing a predetermined key input completion key, the contents of the buffer memory are stored in a predetermined storage area of the storage device 10 (step (14)), and step (1)
Move on to 5). Here, insert an unused magnetic card 6N into the magnetic card insertion part 5.
Step (15) to Step (16)
5, the fixed data A and variable data B' stored in the storage device 10 are converted into recorded information K.
A magnetic helad 5b is attached to the magnetic recording section 6a of the magnetic card as l.
At the same time, as the beginning code and ending code of the magnetic card 6N, the beginning code r$EEJ and the ending code "$EEJ" which become the encryption code D of the master magnetic card 6M are written.
A code D' different from FFl (e.g. r $-E E
J and r$EEJ) to complete the write process. When the writing process is completed, the process moves to step (17), the confirmation mode is set, the drive circuit 12 of the magnetic helad 5b is switched to the continuous output side, and then the process moves to step (18), where the character display section 3 Insert instruction for magnetic card drawer r6-V
erifyJ is displayed. In this state, when the magnetic card 6 is inserted into the magnetic card insertion part 5 again, steps (19) to (20)
), the write information from the magnetic recording section 6a of the magnetic card 6 is read out and temporarily stored in the buffer memory, and the read information matches the recorded information recorded in steps (7) and (16). It is determined whether or not to do so (step (21)). If the two match, the process moves to step (22), where the written information is displayed as is on the character display section 3, and a check mark rk CheckJ is displayed, and then, in step (24), the key switch 4 is turned on. It is determined whether the switch is in the ON state or not, and if the ON state continues, the process moves to step (10), and if the ON state is continued, the process ends. In addition, if the judgment result in step (21) is that the written report and the subsequent information do not match, the process moves to step (23), and a check mark "伽CheckJ" is displayed on the character display section 3, and A specific symbol is displayed at the character position corresponding to the location to clearly visually indicate that there is a mismatch, and an error sound "Beep, Beep, 7. Ping" is emitted to call attention. To correct the discrepancy here, return to step (10) and press the write switch 2c to proceed to step (12).
In step (13), the content of the buffer memory at that time, that is, the same display as in step (23), is displayed, so move the cursor to the corrected part and input the correct data again (step (13)), and then perform the writing process in the same way. Just go. The above is the case where a new card is issued using the unused magnetic card 6N.Next, the case where the contents of a previously issued card are changed, such as when updating an expired card, will be explained. In this case, in step (1o), if the magnetic card 6 to be updated is inserted into the magnetic card insertion part 5 without pressing the write switch 2c (step (25)), the drive circuit 12 enters the continuous output mode. Therefore, the recorded information Kl recorded in the magnetic recording section 6a of the magnetic card 6 is read and temporarily stored in the buffer memory (step (2)
6) ). Then, the fixed data A of the magnetic card 6 and the step (
If the fixed data A of the master magnetic card 6 stored in step 7) matches, the contents of the buffer memory are displayed and the process returns to step (1o). . In this step (10), if the write switch 2C is pressed, the contents of the buffer memory, i.e., the variable data recorded on the magnetic card 6 to be updated, are displayed (step (12)). ), move the cursor to the area where you need to change the expiry date, etc., and enter the desired data. The contents of the magnetic card 6 can be rewritten. In the above embodiment, the master magnetic card 6M
Although the case has been described in which the encryption code D is used as both the start code and the end code of data, the present invention is not limited to this. For example, the 4-digit 67th to 70th digits may be used as the encryption code D area. However, if the start code and end code are used together as the encryption code D, the entire arbitrary data area can be used as the format information Fl.
It has the advantage that it can be used as an area. Further, in the embodiment, a case has been described in which the magnetic card 6 is used as an ID card, but the present invention is not limited to this. For example, the present invention is not limited to this. It can be used for various purposes such as issuing membership cards. Furthermore, the magnetic card encoder can of course be used online, and can also be used as a terminal by connecting online to a host computer via an interface. [Effects of the Invention] As described above, according to the present invention, writing to a new card can be performed only when the encryption code recorded on the master magnetic card matches a predetermined code. Therefore, new cards cannot be issued without using a master magnetic card, and magnetic card counterfeiting and
It has the excellent effect of preventing duplication,
In addition, since fixed data that cannot be rewritten is recorded on the master magnetic card, by preparing multiple types of master magnetic cards, it is possible to easily change a large amount of fixed data without increasing the memory storage capacity. This has an excellent effect. 4.
