At present, the importance of cards in society is increasing day by day, and their functions and types are also diversifying. Magnetic cards have been commercialized since the mid-1900s, and IC cards, which have been commercialized and used in France since 1977, have been developed and used as financial and communication cards. In addition, the bank's cash card or credit card, which is a representative magnetic card, includes not only a transportation card function but also a bonus card function, and is also a global mobile telecommunication (GSM) which currently accounts for more than half of the world's demand. Subscriber Identification Module (SIM) cards are not only used in mobile phone applications, but also in various fields such as finance, medical insurance, broadcasting, transportation, and access control.

As compared with other IT media, magnetic cards and IC cards have been rapidly spread in the short history of less than 50 years, and the fields of application are also diversified, and the demand is continuously increasing. In addition, many private and corporate businesses such as financial institutions, department stores, hospitals, and beauty salons easily produce and issue their own cards to achieve customer satisfaction through customer management. In line with this, card readers / writers are commercially available and commonly used so that individual and corporate businesses can easily produce and issue membership cards and mileage cards.

Hereinafter, a card encoding process using a general card issuer will be described with reference to the accompanying drawings.

1 is a block diagram schematically illustrating the configuration of a general card writer.

Referring to this, when a card such as an IC card or a magnetic card is inserted into the insertion hole 50, it is transported to the control unit 104, 106 or 108, and the control unit 104, 106 or 108 is a magnetic surface. Alternatively, after reading and confirming the information recorded in the IC module, the encoding operation is performed according to the command of the user terminal 90.

The user terminal 90 may be a general personal computer (personal computer, desktop, laptop, etc.) and is connected to the card issuer 100 through a PC interface unit 110 such as an RS232C interface or a USB interface. The user may enable the controller 104 of the card issuer 100 to encode the card through an application program (GUI) or a hardware / firmware control program (HW / FW Control Program) on the terminal to operate the card issuer 100. do.

The card interface unit 102 inserts the card from the insertion port 50, checks whether the inserted card is a magnetic card or an IC card, and if the magnetic card is MS card control unit 106, if the IC card IC card control unit Transfer the card to 108. In the past, the card dispenser has a structure that can be inserted through the card insertion slot of the card dispenser regardless of the shape or type of the card, so that foreign substances such as abnormal cards and toothpicks having a smaller size than the normal cards are inserted. In contrast to the failure, the recent card issuer has a tendency to include various standard sensing devices 60 such as a photo sensor in the card interface in order to prevent the above problem.

In the control unit 104, the inserted card is classified into the card interface unit 102 and the IC module or the magnetic of the card transferred to the corresponding MS card control unit 106 or the IC card control unit 108 according to the type of the card. Read the information recorded on the screen, and receives the command (Command) transmitted from the user terminal 90 through the PC interface unit 110, performs the above command and to perform the encoding according to the type of each card do.

The power supply 112 receives a commercial AC power or a power supply through a connector connected to the user terminal 90, and a card issuer through a commercial regulator such as a switching mode power supply (SMPS). Stable power is supplied to (100). Finally, the display unit 114 may display various error codes or error messages that may occur when inserting, transferring, encoding, or ejecting a card, and commands input through the user terminal 90. The result of the command is shown through an LED or buzzer or an electronic display device 70 such as an LCD provided in the card issuer 100.

2 is a schematic overall perspective view of a general card writer described above.

Referring to FIG. 2, when the card is inserted into the insertion hole 50 of the card issuing machine 100 during the conventional encoding operation, the card issuing machine 100 measures the standard detecting sensor 60 around the insertion hole 50. The twist or abnormal specification of the inserted card is determined, and if the shooting is judged to be normal, it is classified and classified as a magnetic card or an IC card.

Then, as the rotating shaft 122 of the drive motor rotates, the pair of feed rollers 150, 152, and 154 provided in the conveying unit rotates, so that the classified card is used as the corresponding IC card control unit 106 or MS card control unit 108. ), And the control unit 104, 106 or 108 reads and confirms the information recorded on the IC module or the magnetic surface, and if there is no error, the encoding operation continues.

Decelerate the rotating shaft 122 of the drive motor 120 using a plurality of gears or rubber belts 130, 132, 134 and fleeces 140, 142, 144 to adjust the speed when performing the above encoding operation. Then, the reduced rotation is transmitted to the pair of upper and lower feed rollers 150, 152, and 154 for conveying the card, and the reduction gear and the pleats 140, 142, and 144 are frictionally rotated to convey the card. The distance was counted.

However, in the prior art as described above, a lot of noise is generated when driving an operation to decelerate the gears, the rubber belt (130, 132, 134) is worn by a long time operation, irregular jitter by friction (Jitter) is generated so that it is not possible to form the correct bit on the card, and because of this, the distance measured by the above process and the distance actually transferred by the card do not coincide. There was a problem of not being.

In addition, since the backlash is generated by the repulsive force when the gears are rotated by the gears as described above, this causes a problem that the error rate is increased, thereby lowering the reliability of the card issuer. .

The present invention has been proposed to solve the above problems, when inserting the IC card or magnetic card into the card issuer, when performing the encoding operation, the slits in the idle frame rotated with the rotation axis of the drive motor, and the slit By attaching a sensing sensor to calculate the speed of the card, it receives feedback, and adjusts the encoding speed of the drive motor, thereby reducing jitter and backlash caused by friction that occurred during conventional encoding. The purpose is to reduce the error rate.

And by using the system as described above, by adjusting the speed more accurately to encode the card can also achieve the purpose of increasing the reliability of the card issuing machine and maximize the production efficiency.

In order to achieve the above object, the present invention describes a speed adjusting method of the card issuer, and also proposes an apparatus such as an idle frame and a slit, a slit sensor for explaining the method.

The apparatus for speed regulation of a card issuer includes the steps of: inserting, transferring, etc. for encoding, and setting a speed reference value; Adjusting the encoding speed by counting the number of slits detected by the slit sensor according to the speed of the rotating shaft of the driving motor to obtain a speed measurement, and feeding back the calculated speed measurement. Wow; After the encoding operation is finished, verifying that encoding is normally completed, and then ejecting the card.

Preferably, the speed reference value may be input through an application program (GUI) or a hardware / firmware control program of the user terminal before encoding, or may be directly input through a keypad of a card issuer at the time of encoding, and the slit sensor If the speed measurement value measured by the (Slit Sensor) is larger than the speed reference value, the difference (△ = speed reference value-speed measurement value) is added. If the speed measurement value is smaller than the speed reference value, the difference (△ = speed reference value) Adjust the speed by adding -speed measurement value.

Also, in the present invention, when the card is encoded is determined to be an error (Error), the present invention emits an error code (Error Code) or an error message (Error Code) or an error message (Error) Message).

Hereinafter, the preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

3A to 3B are perspective views of an idle frame for showing the operation of the slit sensor before and after driving the rotary shaft of the motor of the card writer according to the present invention.

The slit sensor 206 is connected to the rotating shaft 122 of the drive motor and is located in the idle frame 202 which is rotated as the rotating shaft rotates. The slit 204 is formed on the idle frame 202. The number of slits passing through the slit sensor 206 per track is counted according to the speed of the rotating shaft. The counted number may be calculated in mm / s, which controls the speed of encoding the magnetic card or the IC card in comparison with a reference speed preset by the user.

3A shows the positions of the slit 204 and the slit sensor 206 of the idle frame 202 before the rotation shaft 122 of the motor is driven. The slit sensor 206 may be composed of one or more sensors for more accurate measurement.

3B shows the positions of the slit 204 and the slit sensor 206 of the idle frame 202 after the rotation shaft 122 of the motor is driven. If the idle frame 202 rotates in the counterclockwise direction, the slit 204 also rotates in the direction of the idle frame 202 as shown in the figure, and the slit 204 is moved from the sensor located below the slit sensor 206. Will be detected.

For example, if there is a card dispenser in which 8 bits have been written for one track and 0.4 seconds have been passed through the slit sensor 206, the slit 204 having a length of 10 mm between the slits 204 has passed. The speed of the axis of rotation is (10 * 8) /0.4 = 200 mm / s. At this time, if the set speed reference value is 250 mm / s, △ = 250 mm / s-200 mm / s = 50 mm / s speed should be fed back and added.

Figure 4 is a flow chart for explaining the speed adjustment process of the rotation shaft of the motor of the card issuer according to the present invention.

Referring to Figure 4, first, when the card is inserted into the insertion slot of the card issuing machine, foreign matters such as abnormal cards and toothpicks smaller than the standard card is inserted to detect this, so as to prevent the failure caused by this in advance, For this purpose, a standard detecting sensor such as a photo sensor or a width detecting sensor provided around the insertion hole checks the size of the card.

Subsequently, when it is confirmed that there is no abnormality in the specification, the inserted card is transferred to the IC card control unit or the MS card control unit by rotating the pair of feed rollers provided in the conveying unit while the rotating shaft of the drive motor rotates. The corresponding control unit reads and confirms the information recorded on the IC module or the magnetic surface and is transferred to a position where encoding can be performed (S102).

When the initialization for encoding through the above operation is completed, a speed reference value for adjusting the encoding speed is set (S104). In this case, the speed reference value is input through an application program (GUI) or a hardware interface program (HW / FW Control Program) for driving the card issuer in the user terminal before the encoding operation, or the keypad of the card issuer is used during the encoding operation. Allow direct input via

Next, when the encoding is started, the idle frame rotates at the same speed as the rotation axis of the motor rotates, and the sensor of the idle frame counts the number of slits of the idle frame passing per track, and counts the counted number. It calculates in mm / s unit (S106).

Next, the control unit compares the speed measurement value obtained above with the speed reference value (S108). If the speed measurement value is more than the speed reference value, the speed of writing a bit is faster, so it is slowed down by adding the difference (△ = speed reference value-speed measurement value), and if the speed measurement value is smaller than the speed reference value, Since the speed of writing a bit is slow, the speed is increased by adding the difference (△ = speed reference value-speed measurement value) (S110). Through the feedback process, it is possible to control the speed as fast or slow as possible.

When the encoding process is completed through the above process (S112), it is checked whether the encoding is normally performed (S114). If the encoding process is normally completed, the card is released with a message that the operation is normally completed. If an error occurs during the encoding operation (ERROR A), an error code corresponding to an electronic display device such as an LED or an LCD of the display unit 114 of the user terminal 90 and the card issuer 100 or An error message is displayed, and the inserted card is ejected (S116) to end the above operation.                     

As mentioned above, although this invention was demonstrated in detail using the preferable embodiment, the scope of the present invention is not limited to a specific embodiment and should be interpreted by the attached claim. In addition, those skilled in the art should understand that many modifications and variations are possible without departing from the scope of the present invention.

As described above, according to the present invention, when encoding a card issuer that manufactures an IC card, a magnetic card, or the like, the jitter caused by friction is controlled by receiving a feedback of the current card speed and adjusting the speed of the rotating shaft of the driving motor. By reducing the error rate due to jitter and backlash, the speed can be adjusted more precisely, and the card can be encoded to increase the reliability of the card issuer and maximize the production efficiency.

By using the system as described above, customer satisfaction by supplying more reliable and stable card issuer to individual or corporate business that needs member management and customer satisfaction service in financial sector such as bank, department store, large mart, beauty salon, etc. Can increase the effect.
