[Industrial applications]

 The present invention relates to a card data reading device connected to a prepaid card terminal, an online terminal, a vending machine, and the like. Specifically, it is prepared by pasting a used card such as a prepaid card (prepayment card). The present invention relates to a card data reader that detects fraudulent cards.

[0002]

[Prior Art]

 Magnetic cards are widely used today as a convenient medium for handling simple data. And, for example, prepaid cards are used for various purposes because they can be used as a substitute for payment. In addition, since the above prepaid card can be used as a cash substitute, standard use is not publicly announced.

[0003]

[Problems to be solved by the device]

 However, recently, some people have come up to use modified cards by cutting and pasting used cards such as the above prepaid cards. In the conventional card data reading device, illegal cards created by pasting used cards together were dealt with by detecting the thickness, etc., but this is within the error range of detection accuracy. However, it could not be detected as a fraudulent card. Then, it is clear that the fraudulent card can be accurately detected by detecting the difference in strength due to the pasting of the fraudulent cards created by pasting. An object of the present invention is to detect a fraudulent card based on the difference in strength and to prohibit the use of the fraudulent card.

[0004]

Means for Solving the Problems The means of the present invention are as follows. The reading means 1 (see the functional block diagram of FIG. 1, the same applies hereinafter) is for reading the data recorded on the carried card, for example, a carrying roller for reading the magnetic data recorded on the inserted card, For example, a magnetic head. The card bending mechanism 2 is a rotating member or a solenoid that rotates by rotating one end of the conveyed card to bend the card. The storage means 3 is a ROM or the like that stores flexure state data indicating a flexing condition when a normal card (regular card) is flexed. The flexure state detecting means 4 detects the flexure state when the conveyed card is flexed by the card flexure mechanism 2. For example, a plurality of light emitting elements and light generated from the light emitting elements are located at positions where card flexure can be detected. A light receiving element for receiving the light is arranged in an array, and the bending condition of the card is detected by the light receiving state when the card is bent. The discriminating means 5 discriminates an unauthorized card by comparing the flexure state detected by the flexure state detecting means 4 with the flexure state data read from the storage means 3, and is executed by, for example, a CPU. The control means 6 performs predetermined data processing based on the output of the reading means 1 and, when the discrimination means 5 discriminates that the card is an illegal card, controls the execution of the predetermined data processing. It is executed by the CPU.

[0005]

[Action]

 The operation of the means of the present invention is as follows. First, it is assumed that the storage unit 3 stores the bending state data when a normal card is bent. When the card is moved at a constant speed, the data recorded in the card is read by the reading means 1 and output to the control means 6. When the card is moved to the card bending mechanism 2, the card bending mechanism 2 bends the card, and the bending state is detected by the bending state detecting means 4 and output to the discriminating means 5. The discriminating means 5 compares the detected card flexure state with the normal card flexure state data stored in the storage means 3 to discriminate whether or not the card is an illegal card, and outputs the result to the control means 6. To do. The control means 6 executes normal data processing based on the output of the reading means 1, and controls so as not to perform the processing when the card is an illegal card. Therefore, it is possible to detect a fraudulent card based on the difference in strength and prohibit the use of the fraudulent card.

【Example】

 An embodiment will be described below with reference to FIGS. 2 to 12 are views showing a card data reading device.

First, the configuration will be described. 2 is a diagram showing the overall configuration of the card data reading device 11, FIG. 3 is a sectional view taken along the line AA ′ of FIG. 2, FIG. 4 is a sectional view taken along the line BB ′ of FIG. 2, and FIG. It is a perspective view. 2 to 5, reference numeral 11 denotes a card data reading device, and a card insertion port 11b for inserting a card into the main body 11a of the card data reading device 11 and ejecting after reading the data is formed. A card insertion sensor 12 for detecting the insertion of the card 30 is installed in the card insertion opening 11b of the main body 11a, and inside the conveyance rollers 13 and 14 for pulling the card 30 deep and ejecting it, and conveyance rollers 13, Roller driving motors 15 and 16 for driving 14, a magnetic head 17 for reading and writing the magnetic data recorded in the inserted card 30, and one end of the card conveyed to the inside are sandwiched and rotated. A light emitting portion 19 having a bending mechanism 18 for bending the card and a plurality of light emitting elements (for example, light emitting diodes) 19a arranged along the bending shape of the card and emitting light when the card is bent (see FIG. 6) and a light receiving section 20 (FIG. 6) having a plurality of light receiving elements (for example, phototransistors) 20a for receiving light from the light emitting element 19a of the light emitting section 19 are installed. That.

The card insertion sensor 12 is composed of, for example, a light shielding sensor, and when the card 30 passes the card insertion sensor 12, the insertion / ejection of the card 30 is detected by the presence or absence of light shielding.

The bending mechanism 18 includes a “U” -shaped rotating member 41 that is rotatable when the conveyed card is stopped and bent, and a rotating member that is attached to the upper end of the rotating member 41. The support shaft 42 supporting 41, the crank 43 attached to the lower end of the rotating member 41, the bending solenoid 44 rotating the crank 43, and the conveyed card contact the inside of the rotating member 41. And a contact sensor 45 for detecting the stop. Therefore, when the bending solenoid 44 is energized and the rod 44a is pulled in as shown in FIG. 5, the crank 43 causes the rotating member 41 to rotate about the support shaft 42 in the direction shown in the figure. When the card contact signal from the contact sensor 45 is received, the bending solenoid 44 is energized, and at the same time, the roller driving motor 16 is stopped so that the transport roller 14 does not move. Will be able to bend.

The light emitting section 19 emits light from one side surface of the card 30 when the card is bent by the bending mechanism 18, and the light receiving section 20 receives the light from the other side surface. The bending state is detected, and the light emitting section 19 and the light receiving section 20 function as a bending sensor 21 as a whole. The arrangement of the light emitting element 19a of the light emitting section 19 and the light receiving element 20a of the light receiving section 20 is shown in FIG. As shown in this figure, the light emitting element 19a and the light receiving element 20a are arranged so as to match the degree of bending when the regular card is bent by the bending mechanism 18. Since the degree of bending by the regular card is approximate to a parabola, the data based on the degree of bending by the regular card is called parabolic data (see FIG. 8) and is stored in the ROM 52 described later in this embodiment.

FIG. 7 is a block diagram showing a control unit of the card data reading device 11. In this figure, reference numeral 51 denotes a CPU that controls the entire apparatus and performs various data processing including data reading processing and data arithmetic processing, which will be described later. The CPU 51 and the RAM 53 according to a microprogram stored in the ROM 52. While exchanging data between them, values required for various operations are calculated, and various operations of the card data reader 11 are controlled by the controller 51a. The CPU 51 has a ROM 52 for storing a predetermined program and fixed data, a RAM 53 for temporarily storing data used for calculation and a calculation result, and an input / output of external terminals and data based on an I / O command. The external interface 54 for outputting, the magnetic head 17 for reading the data stored in the card or writing predetermined data, and the drive for driving the transfer rollers 13, 14 for transferring the inserted card at a constant speed. Sensor 15, a card insertion sensor 12, a bending sensor 21 for detecting the bending state of the card, and a contact sensor 45 for detecting contact with the inside of the card bending mechanism 18 And the bending mechanism 18 for bending the card are connected.

In the ROM 52, the bending data corresponding to the bending condition of the regular card is stored as parabolic data 52a as shown in FIG.

Further, the RAM 53 is used as a so-called working memory for temporarily storing the write data 53a, the deflection sensor data 53b detected by the deflection sensor 21, the calculation result and the like. FIG. 9 is a view showing the bending data 53b detected by the bending sensor 21. In this case, the number of bits of the flexure data 52a by the regular card and the flexure data 53b detected by the flexure sensor 21 correspond to the number 14 of the light emitting elements 19a (light receiving elements 20a) and become the bit data of 14 bits. All the bits of the flexure data 52a are "1", and some bits of the flexure data 53b detected by the flexure sensor 21 are "0".

Next, the operation of this embodiment will be described. FIG. 10 is a flowchart showing a card data reading process, and this flow starts when the insertion sensor 12 of the card 30 detects the process.

First, in step S1, it is determined whether or not the card 12 is inserted, and when the card insertion is detected, the forward rotation control of the drive motors 15 and 16 is performed in step S2. As a result, the drive motors 15 and 16 rotate in the forward direction to rotate the conveying rollers 13 and 14 and convey the magnetic card 30 in the depth direction at a constant speed. Next, in step S3, magnetic data is read from the magnetic card 30 being conveyed, and in step S4, the contact sensor 45 detects whether or not the magnetic card 30 contacts the rotating member 41 of the bending mechanism 18. .. When the magnetic card 30 abuts, it is determined that the magnetic card 30 has been transported to a predetermined position for bending, and the drive motors 15 and 16 are stopped in step S5, and the bending solenoid 44 is turned on in step S6. When the bending solenoid 44 is energized, the rod 44a of the bending solenoid 44 retracts, and the crank 43 and the rotating member 41 rotate by a predetermined amount accordingly to bend the magnetic card 30. If the magnetic card 30 is not in contact, it is determined that the card is in the middle of being conveyed and is not in a condition for bending, and the process returns to step S2.

In step S7, it is determined whether or not a predetermined time has elapsed since the drive motors 15 and 16 were stopped and the bending solenoid 44 was turned on. If the predetermined time has elapsed, the card bends to a predetermined value. It is determined that the state is in the state, the data detected by the deflection sensor 21 is stored in the RAM 53 in step S8, and the energization of the deflection solenoid 44 is turned off in step S9. Next, in step S10, the flexure data detected by the flexure sensor 21 is compared with the flexure data (parabolic data) obtained by the regular card, and it is determined whether or not the difference is a predetermined value or more (for example, four or more). If the difference in flexure data is less than 4, it is determined that the inserted magnetic card 30 is not an illegal card, and it is determined in step S11 whether or not there is data to be written in the magnetic card 30, and the write data is written. If there is, the drive motors 15 and 16 are reversely rotated in step S12, and the transport rollers 13 and 14 are transported in the reverse direction. That is, the card data reading device 11 is actually connected to a data processing device on the center side (not shown), and whether the writing data is sent from the device on the center side to the card data reading device 11 (for example, the card). If 30 is a prepaid card, the data read in step S3 is held in the device on the center side, and when shopping or the like, the data obtained by subtracting the amount is sent to the card data reading device 11) When the data is sent, the process proceeds to step S12. In step S13, the magnetic head 17 writes data to the magnetic card 30 conveyed to the ejection side, and in step S14, the insertion sensor 12 determines whether or not the card 30 is ejected. When the card 30 is not ejected, the process returns to step S12, and when the card 30 is ejected, the process proceeds to step S17. That is, when the difference in the flexure data is less than 4 in step S10, the flexure of the card 30 is the same as or very close to the flexure of the regular card as shown in FIG. ..

On the other hand, when the number of bits of the flexure data is different by 4 or more in step S10, it is determined that the card is an illegal card such as when the card is bent halfway as shown in FIG. In step S15, error processing is performed, and in step S16, the drive motors 15 and 16 are reversely rotated to reversely rotate the transport rollers 13 and 14, and the card 30 is discharged as it is. In this way, when it is determined that the card is a fraudulent card, the transaction is not processed by the error processing and the card is discharged as it is.

In step S17, the above-mentioned respective controls (controls for driving the drive motors 15 and 16) are stopped, the flexure data and the like detected by the sensor 21 are cleared, and the process returns to step S1 to finish the present process.

By performing the above processing, the following operations are performed in terms of hardware. First, when the card 30 is inserted into the insertion port 11b of the card data reading device 11, the insertion is detected by the insertion sensor 12, and the drive motors 15 and 16 operate to rotate the respective conveyance rollers 13 and 14 to convey the paper. The roller 14 pulls the card 30 to the position shown in FIG. At this time, the magnetic head 17 reads the data. The card 30 that has been pulled all the way hits the bending sensor 45 provided at the back of the rotating member 41 of the bending mechanism 18 and stops. Then, the bending mechanism 18 moves to bend the card 30. When bent, light is emitted from the light emitting portion 19 on the side surface of the card 30, and the light receiving portion 20 receives the light to detect the degree of bending. In the case of a regular card, the bending condition draws a parabola as shown in FIG. The deflection data of this regular card is stored in advance as parabolic data and is compared with the deflection data of the insertion card. If the cards are pasted together in the middle, they will be bent as shown in FIG. 12 * and will not match the stored flexure data, so it can be determined as an illegal card.

As described above, the card data reading device 11 of the present embodiment records on the conveying rollers 13 and 14, the roller driving motors 15 and 16 that drive the conveying rollers 13 and 14, and the inserted card 30. The magnetic head 17 for reading and writing the stored magnetic data, the bending mechanism 18 for bending the card by rotating the card 30 by resting one end of the conveyed card 30, and the card is bent by the bending mechanism 18. At this time, the light emitting section 19 emits light from the side surface of the card, and the light receiving section 20 receives the light to provide a bending sensor 21 for detecting the bending state, and the bending state detected by the bending sensor 21 is stored in advance. Since the comparison is made with the bending condition of a legitimate card that is present, it is possible to detect a forged card that has been pasted together with high accuracy, and it is possible to perform security against unauthorized cards Can be increased.

In this embodiment, the card is bent in the vertical direction. However, by adding a new bending sensor and bending mechanism to improve the holding of the card, the bending condition in the horizontal direction is also increased. Can be detected. In this way, it is possible to identify illegal cards with different bonding directions.

Further, in the present embodiment, the solenoid 44 is used as the bending mechanism 18 for bending the card, but any device that can bend the card may be used. For example, the roller is used to move the card to the side plate. You may read it by pressing it.

Furthermore, in the present embodiment, a plurality of (14) light emitting elements / light receiving elements are used as the deflection sensor, but it goes without saying that the types and the number of such members are not limited to those in the above-described embodiments. .. Further, a micro switch may be used instead of the optical sensor.
