Description

Description: TECHNICAL FIELD The present invention relates to a magnetic card encoder capable of writing or reading recorded information on a magnetic card having a magnetic recording unit.

[Conventional technology]

This type of magnetic card encoder generally has one magnetic head for both writing and reading, and records predetermined recording information in a magnetic recording portion such as a magnetic stripe formed on a magnetic card by this magnetic head, Alternatively, the recording information recorded in the magnetic recording unit is read out. And
Two types of selection switches, a write selection switch and a read selection switch, are separately provided to selectively write and read recorded information, and the write mode or the read mode is selected by appropriately switching these. In general, in the read mode, a method of simply reproducing the recorded information written in the magnetic recording unit to the display unit is adopted.

[Problems to be solved by the invention]

However, in the conventional general magnetic card encoder as described above, the write mode and the read mode are selected by the two kinds of selection switches, that is, the write selection switch and the read selection switch. After writing the record information in the magnetic recording section in the embedded mode, it is very troublesome to press the read selection switch to select the read mode every time the written information is confirmed, and switching to the read mode is performed. There is a problem in that the written information cannot be confirmed if the above is neglected. In this case, it is conceivable to employ a two-head system in which a write head and a read head are arranged in parallel to perform writing and reading at the same time. However, in this two-head system, the magnetic head itself becomes very expensive and the encoder is large. It has the drawback of becoming

Further, in the past, in order to confirm the write information after writing the record information in the magnetic recording portion in the write mode, the correct write information and the read information displayed by selecting the read mode (actually, the recorded information When it is determined whether or not there is a match with the written information), the read information displayed one by one must be compared character by character with the original that is the source of the written information, which is extremely complicated. I was forced to do a lot of work.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention provides a magnetic card encoder of a magnetic card in which a predetermined recording information is written in or read from a magnetic recording unit of a magnetic card inserted in a magnetic card insertion unit. A recording information input keyboard for keying in the recording information to be written to, a mode selecting means for selecting a writing mode and a reading mode, and the end of writing the recording information when the writing mode is selected by the mode selecting means. After that, the mode is automatically switched to the read mode, and the mode switching means for displaying the message of the re-insertion instruction on the display unit to prompt the re-insertion of the magnetic card for which the recording information has been written into the magnetic card insertion section, and the re-insertion instruction. The read information read from the magnetic recording section of the magnetic card reinserted into the magnetic insertion section according to And a write information confirmation means for displaying a check display for prompting confirmation of the comparison determination result on the display unit and the comparison determination result by the write information confirmation means do not match. In this case, an error display means is provided for replacing the character corresponding to the mismatched portion with a specific symbol and displaying the replaced character.

[Operation] In the magnetic card encoder of the present invention, when the writing of the record information is completed while the writing mode is selected by the mode selecting means, the reading mode is automatically selected by the mode switching means, and at that time, the writing mode is selected. Whether or not the write information recorded in the magnetic recording portion of the magnetic card and the read information is judged by the built-in information confirmation means, and if the judgment result is an error, the error display means clearly displays the error location. It is an object of the present invention to solve the above problems of the conventional device.

The processing procedure of the arithmetic processing unit 9 will be described below with reference to the flowchart shown in FIG.

When the key switch 4 is turned on, the process shown in FIG. 3 starts to be executed. First, in step, it is determined whether or not a predetermined encryption code is input from the keyboard 2, and when the predetermined encryption code is not input, The process waits until the encryption code is input, and when the correct encryption code is input, the process proceeds to step.

In this step, it is determined whether or not the write / read selection switch 2c on the keyboard 2 has been pressed, and the selection switch
When 2c is pressed, the process moves to step.

In step, it is determined whether or not the writing mode has been set in the previous process, and when the previous process is the reading mode, the process proceeds to step.

In this step, the drive circuit 12 of the magnetic head 5b is switched to the writing side and the writing mode is set to allow the input signal from the keyboard 2, and then the process proceeds to the step where the writing information is input from the keyboard 2. It is determined whether or not the write information is not input, and the process waits until the write information is input, and when the write information is input, the write information is stored in the storage device 10 and then the process proceeds to step.

In the step, it is determined whether or not the magnetic card 6 has been inserted into the magnetic card insertion portion 5, and when the magnetic card 6 is in the non-inserted state, it waits until the magnetic card 6 is inserted and the magnetic card 6 is inserted. Then, the process moves to the step.

In the step, the write information input in the above step is magnetically recorded in the magnetic recording portion 6a of the magnetic card 6 inserted into the magnetic card insertion portion 5 via the magnetic head 5b, and then the step is performed.

In this step, the confirmation mode for confirming the write information written in the above step is set.

In this confirmation mode, the drive circuit 12 for the magnetic head 5b is
To the reading side.

Then, the process proceeds to the step, and the re-insertion instruction to re-insert the magnetic card 6 into the magnetic card insertion portion 5 (for example, "
After “Verify” is displayed on the display unit 3, the process proceeds to step.

In the step, similarly to the step, it is determined whether or not the magnetic card 6 has been inserted into the magnetic card insertion portion 5, and when the magnetic card 6 is in the non-inserted state, it waits until the magnetic card 6 is inserted and the magnetic card 6 is inserted. When 6 is inserted, the process proceeds to step.

In this step, the check mode is set, the write information written in the magnetic card 6 is read through the magnetic head 5b, the write information is read, and both are compared and collated to determine whether they match. . At this time, if they match, the process moves to step, and if they do not match, the process moves to step.

In the step, the writing information (= reading information) is displayed on the display unit 3 as it is and a check display (for example, “Ch
key switch 3 at the same time that the "eck" character is displayed.
Determines whether or not it continues to be in the on state. If it is in the on state, the process proceeds to step to set the normal read mode, and if it is in the off state, the process is terminated.

In addition, in the step, together with the check display, the display unit 3 displays the disagreement portion between the read information and the corresponding write information.
Specific symbols (for example, "?" Or shaded "□")
At the same time as is displayed with, an error sound consisting of a continuous sound of, for example, "pi, pi, pi" is emitted and then the process proceeds to step.

Further, when the write / read selection switch 2c is not pressed in the above step, the process shifts to the step, the drive circuit 12 of the magnetic head 5b is switched to the read side, and the magnetic card 6 is read.
When the card is inserted into the magnetic card insertion section 5, the recording information magnetically recorded in the magnetic recording section 6a is read out through the magnetic head 5b, and this is displayed on the display section 3 before proceeding to the step.

Similarly, when the writing mode is once set in the previous process in step, the process proceeds to step.

Here, step to step and step processing are specific examples of mode selecting means, step processing is specific example of mode switching means, and step processing is specific example of write information confirming means, Further, the processing of steps is a specific example of the error display means.

Next, the operation will be described. In order to write the record information in the magnetic recording unit 6a of the magnetic card 6, first, the key switch 4 of the magnetic card encoder is turned on. In this state, the arithmetic processing unit 9 starts executing the arithmetic processing of FIG.

Therefore, first, enter the preset encryption code into the keyboard 2
Enter from. If the entered encryption code is correct, the process moves from step to step. At this time,
If the write / read selection switch 2c is pressed within the predetermined time, the process moves to step to determine whether or not the write / read selection switch 2c is pressed an odd number of times. It is determined that the embedded mode is selected, and the process proceeds to step. Therefore, the write mode is set in this step, and the drive circuit 12 of the magnetic head 5b is switched to the write side. In this state, when a desired key of the keyboard 2 is selected and, for example, the magnetic card 6 is used as an ID card, write information such as name, identification code number, and department code is input by keying, and this writing is performed. Information is temporarily stored in the storage device 10 (step).

Then, insert the magnetic card 6 into the guide groove 5a of the magnetic card insertion portion 5.
When the magnetic recording portion 6a is inserted into the magnetic recording portion 6a and slidably contacts the magnetic head 5b, the write information is read from the storage device 10 through the step, and this is read through the magnetic head 5b. Written in 6a.

When the writing of the write information is completed, the process moves to the step and the confirmation mode (read mode) is set, and the magnetic head 5b
The drive circuit 12 of is switched to the reading side, and then the process proceeds to the step to instruct the display unit 3 to re-insert the magnetic card 6.
Verify ”is displayed.

In this state, when the magnetic card 6 is inserted into the magnetic card insertion portion 5 again, the process moves from step to step,
The write information in the magnetic recording unit 6a of the magnetic card 6 is read, and it is determined whether the read information matches the write information written in the above step. If the two match, the process proceeds to step to display the write information as it is on the display unit 3 and a check display “Check” is displayed to determine whether or not the key switch 4 is in the ON state. ,
When the ON state is continued, the process proceeds to step and then to read, and thereafter the read mode is set and the data is recorded in the magnetic recording portion 6a of the magnetic card 6 inserted into the magnetic card insertion portion 5. The recorded information is read out and displayed on the display unit 3 as it is, and if it is in the off state, the process ends.

If the determination result of the step is a mismatch between the write information and the read information, the process proceeds to step and the display unit 3
A check mark "Check" is displayed on the screen, and a specific symbol is displayed at the character position corresponding to the unmatched portion, so that the unmatched condition is clearly displayed, and an error sound "Pip, Pip, Pip" is emitted. To call attention.

In the above embodiment, the case where the magnetic card 6 is used as an ID card has been described. However, the present invention is not limited to this, for example, issuing a card for an entrance management device, issuing a magnetic reading type time card, or recording a shopping item. It can be used for any purpose such as creation.

The magnetic card encoder can be used not only online but also as a terminal by connecting online to a host computer through an interface.

It is also possible to print out the read information by connecting a printer or the like to the magnetic card encoder, and in this case, when the determination result in the above step is inconsistent, the character corresponding to the inconsistent portion is a specific symbol (for example, "?"). etc)
It may be printed with.

〔The invention's effect〕

As described above, according to the present invention, when the writing mode is selected by the mode selecting means, the reading mode is automatically set after the writing of the writing information to the magnetic recording portion of the magnetic card is completed. , Since the message of the re-insertion instruction prompting to insert the magnetic card for which writing has been completed into the magnetic card insertion portion again is displayed on the display portion, not only the switching operation from the writing mode to the reading mode is unnecessary. It is possible to notify the operator that the writing operation to the magnetic card has been performed, and at the same time, prompt the user to confirm the writing information, so that the confirming operation can be surely performed.

Then, according to the message of the re-insertion instruction, the read information read from the magnetic card inserted into the magnetic card insertion portion is compared with the write information key-input to write to the card, and the correctness determination is automatically performed. At the same time, a check display prompting the user to confirm the determination result is displayed on the display section, so that the display section does not simply display the write information read from the magnetic card, but the write information that is correct or incorrect. Since the operator is informed that is displayed, there is no fear that the write information of the magnetic card is erroneously read in the normal read mode and the error in the write information is overlooked.

Further, as a result of the correctness determination, when the write information and the read information do not match, the character corresponding to the mismatched portion is displayed by being replaced with a specific symbol, so that the operator can instantly know the errored portion. There are various excellent effects that can be corrected immediately.
