Description

[Detailed Description of the Invention] [Object of the Invention] (Field of Industrial Application) The present invention relates to an information recording or reproducing device for preventing unauthorized use, forgery, etc. of various cards such as cash cards and credit cards. be.

(Conventional technology) The card is currently a cash card for bank transactions.

It is widely used in the form of credit cards for product transactions.

Among such cards, a magnetic card usually has a magnetic stripe of a predetermined width formed on its front or back surface, and information unique to the card owner is recorded on the magnetic stripe in the form of magnetic data.

A conventional example of a magnetic recording system for such a magnetic card will be explained with reference to FIGS. 5(ao) and 5(b).

In FIG. 5(a), the longitudinal direction of the recording area 31 is the direction perpendicular to the longitudinal direction of the magnetic stripe 30 formed by arranging magnetic material in a strip shape on the magnetic card, and the longitudinal direction of the recording area 31 is This figure shows a state in which magnetic recording is performed with the longitudinal direction of the gap of the magnetic head aligned.

Here, the angle formed by the longitudinal direction of the recording area 31 and the longitudinal direction of the gap of the magnetic head is defined as a "magnetization angle". According to this definition, in the magnetic recording state shown in FIG. 5(a), the magnetization angle is 0 degrees.

FIG. 5(b) shows the magnetic recording state when the magnetization angle with respect to the magnetic stripe 30 is uniformly +0 degrees.

In this way, the magnetic recording method in conventional magnetic cards is
Since the magnetization angle is 0 degrees or uniformly +0 degrees, the following problems arise.

In other words, in the conventional magnetic recording method, the magnetization angle is 0 degrees or uniformly +0 degrees, so if a magnetic card is used as a cash card for bank transactions, for example, if the magnetic card is lost or stolen, it may be lost or stolen. Once in the hands of a magnetic card, the PIN number etc. recorded on the magnetic card can be easily identified by reading the magnetic card, and as a result, there is a problem in that the magnetic card becomes a target for unauthorized use such as using a cash dispenser. .

In addition, in the case of magnetic cards using the conventional magnetic recording method, it is also possible to copy the information on another person's card to another magnetic card relatively easily by using the magnetic card reading function described above. Nowadays, magnetic cards are widely used, and it is necessary to take measures to prevent unauthorized use and damage.

(Problems to be Solved by the Invention) As mentioned above, in various commercial transactions using cards using conventional recording methods, there is a high risk of fraudulent use, card forgery, and tampering due to the simplicity of the recording method. There is a problem.

To solve this problem, the present invention employs a special recording method to record or reproduce information that makes it difficult to forge or tamper with the card and prevent unauthorized use. Means) The information recording or reproducing apparatus of the present invention is an apparatus for recording or reproducing information on a recording track on a card while conveying the card, and in which the information recording or reproducing head and the gap direction of this head are varied. It has a driving means, and the driving means records or reproduces information while varying the longitudinal direction of the recording track on the card and the gap direction of the head that records with respect to the recording track according to a predetermined pattern. This is what I did.

(for production) Next, the operation of the device having the above configuration will be explained.

First, a case will be described in which specific information is recorded on a recording track provided on a card.

With a card inserted into this device, the driving means drives the head along the recording track while varying the gap direction of the head with respect to the longitudinal direction of the recording track provided on the card according to a predetermined pattern. . At the same time, the head records specific information according to the pattern!
Record it on Heratsuk.

A card on which specific information according to a predetermined pattern is recorded in this manner is inserted into this device and the information is read.

That is, the driving means drives the head according to the above-described predetermined pattern with respect to the recording track of the inserted card, and reproduces the information recorded on this recording track.

Due to the above-described operation of this device, specific information is reproduced from a genuine card, so if information based on a predetermined pattern is not recorded on the inserted card,
If information based on a different pattern is recorded, the device stops moving on to the next transaction.

(Example) Examples of the present invention will be described in detail below.

The embodiment shown in FIG. 1 includes a recording/reading means 1, an I control means 2, and a card transport means 3.

The control means 2 includes a CPU 4 that controls the entire device;
As shown in FIG. 2, a change pattern generating section 6 stores change pattern information regarding the magnetization angle with respect to the magnetic recording track (for example, magnetic stripe) 22 of the card 21 and sends it to the CPLJ bus 5 under the control of the CPU 4. It is configured with

The recording/reading means 1 includes a magnetic head 7 that records and reproduces recorded information (specific information such as an owner number and designation that differs for each card owner) on the magnetic recording track 22.
, a recording control section 8 connected to the CPU bus 5 to perform recording control on the magnetic head 7, a read control section 9 connected to the CPU bus 5 and controlling reproduction by the magnetic head 7, that is, reading control; A magnetization angle changing mechanism section 10 is connected to the CPU bus 5 and serves as a driving means for supporting the magnetic head 7 and changing the magnetization angle during recording and reading of recorded information on the magnetic recording track 22 of the magnetic head 7, and , takes in the change pattern information from the change pattern generation section 6, and based on this, the magnetization angle variation mechanism section 1
The magnetization angle control section 11 controls the magnetization angle.

The card transport means 3 is connected to a card transport mechanism section 12 for inserting and ejecting the card 21 into and out of the device, and a CPU bus 5, and is controlled by the CPU 4 to insert the card 21 into the card transport mechanism section 12. It is configured to include a card transport control section 13 that sends signals for drive and ejection drive.

The magnetization angle varying mechanism section 10 as the driving means has a third
As shown in the figure, there is a magnetic head support arm 14 whose central portion is rotatably supported by a column 20 provided on a substrate 19, and whose inner peripheral portion is fixed to one end of the magnetic head support arm 14. It has a cylindrical screw body 15 provided with a screw, and a drive motor 18 that drives a rotary screw body 16 screwed into the screw of the cylindrical screw body 15 via a reduction gear 17,
The magnetic head 7 is supported at the other end of the magnetic head support arm 14, and the entire structure is configured to be movable in the longitudinal direction of the magnetic recording track 22 (in the direction of arrow X).

When the magnetic recording track 22 is moved in the longitudinal direction, a control signal based on the change pattern information is sent from the recording angle control section 11 to the drive motor 18, thereby causing the drive motor 18 to rotate by a predetermined amount. Screw body 1
6 is rotated, and the rotation of the rotary screw body 16 causes the magnetic head support arm 14 supporting the cylindrical screw body 15 and the magnetic head 7 to be displaced in the direction of the arrow Y about the pillar 20. At this time, the magnetization angle of the magnetic head 7 with respect to the magnetic recording track 22 is determined as +θ degrees, − degrees, as shown in FIG. 4 based on the change pattern information.
It is designed to take two values of θ degrees.

Next, the operation of the embodiment apparatus having the above configuration will be explained.

First, the case where recording information is recorded on the magnetic recording track 22 of the card 21 will be explained.

When the card 21 is inserted into the card transport mechanism section 12, the card transport mechanism section 12 is controlled by the card transport control section 13, and carries the inserted card 21 to a predetermined position facing the movement area of the magnetic head 7.

In this state, the change pattern generation section 6 controlled by the CPU 4 sends the change pattern information stored in advance to the recording control section 8 and the magnetization angle control section 11 via the CPU bus 5.

The magnetization angle control section 11 first sends a control signal to the drive motor 18 based on the change pattern information to rotate it by a predetermined amount, and sets the magnetization angle of the magnetic head 7 with respect to the magnetic recording track 22 to +θ degrees. At the same time, the recording control section 8 which has taken in the change pattern information sends a change pattern code to the magnetic head 7.

Thereby, the magnetic head 7 records the changed pattern code in the pattern code recording section 23 with the magnetization angle being +θ degrees.

Next, the magnetization angle control section 11 sequentially sends control signals corresponding to predetermined change pattern information to the drive motor 18, and the recording information control section 8 sends recording information to the magnetic head 7. As a result, recorded information is recorded in the information recording portion 24 of the magnetic recording track 22 in a state having magnetization angles of +θ degrees and −θ degrees corresponding to the change pattern information, as shown in FIG.

Incidentally, the method of recording the recorded information in the information recording section 24 is as follows.
For example, when magnetizing this information recording section 24,
If the case of no magnetization is assumed to be "0 par", an F/2F method can be used in which the frequency when recording "1" is twice the frequency when recording "Oee".

Next, a case will be described in which the pattern code and the recorded information are reproduced from the card 21 on which the pattern code and the recorded information are recorded as described above.

When the owner of this card 21 inserts his/her own card 21 into the card transport mechanism 12, this card 21 is carried to a predetermined position facing the moving area of the magnetic head 7 in the same manner as in the above-mentioned recording process. be done.

In this state, the change pattern generating section 6 first sends change pattern information of +θ degrees to the magnetization angle control section 11, thereby setting the magnetic head 7 of the magnetization angle variation @ structure 10 to +θ degrees, and the CPU 4 controls reading. The change pattern code recorded in the pattern code recording section 23 is read by controlling the section 9.

The read change pattern code is passed to the magnetization angle control section 11 under the control of the CPU 4, and the magnetization angle control section 11 then controls the drive motor 18 of the magnetization angle variation mechanism section 10 as shown in FIG. Control signals representing magnetization angles of +θ degrees and -θ degrees are sent. As a result, the drive motor 18 sets the magnetization angle of the magnetic head 7 with respect to the magnetic recording track 22 to +θ degrees and -0 degrees in accordance with this control signal.

Then, in synchronization with the setting of the magnetization angle of the magnetic head 7, the magnetization angle variation mechanism section 10 itself moves in the longitudinal direction of the magnetic recording track 22, and the owner-specific record recorded in the information recording section 4 is moved. Play information.

The reproduced recorded information is judged to be true or false by CPtJ4 of the control means 2, and if it is judged to be true, the process moves to the next step.

On the other hand, if it is determined to be false by CPt, 14, or the changed pattern code of the card 21 is recorded at a magnetization angle different from that shown in FIG. 4, the magnetic head 7 cannot reproduce the changed pattern code. If so, the device aborts the transition to the next step and
1 is returned, and if necessary, an alarm is issued by an alarm means (not shown) to notify that the used card 21 is not genuine.

The present invention is not limited to the embodiments described above, and various modifications can be made within the scope of the invention.

For example, in the embodiment described above, the magnetization angle is +θ degrees.

Although we have explained the case where recorded information is recorded and reproduced as two values of -θ degrees, this is not limited to this, and the same implementation can be performed with three or more values, and in this case, tampering with the magnetic card can be more effectively prevented. .

The magnetization angle of the magnetic head can be set by the magnetization angle varying mechanism using the drive motor, for example, by turning on the electromagnet.
, OFF can also be realized.

Roughly speaking, in the above embodiment, only the magnetic card was explained, but the same method can be applied when reproducing a laser memory card using an LED (semiconductor light emitting element), CC0 (photoelectric conversion element), etc. Can be done.

[Effects of the Invention] According to the present invention detailed above, since specific information is recorded and reproduced on a card based on a predetermined pattern, it is possible to prevent forgery, falsification, etc., and prevent unauthorized use. It is possible to provide an information recording or reproducing device that can prevent damage from occurring.
