Description

DETAILED DESCRIPTION OF THE INVENTION +a+ Field of Industrial Application This invention relates to a card issuing device that writes necessary card data to a card on which security data has been written in advance and issues the card.

(b) Prior Art FIG. 1 shows the mechanism of a general card issuing device that writes predetermined card data onto a magnetic card and issues the card.

In FIG. 1, BEI to BE4 are card transport routes for transporting cards, and form a card transport path between the card stocker and the card discharge port. These card transport healds BE1 to BE4 are each transported by a card transport motor MOT1. When the card stocker is filled with many carts in which no card data has been written yet, and the card feeding clutch CLI is turned on, the cards in the cart stocker are transferred to the card 1 general transport held B.
It is rolled out between EI and BE2. The drawn-out card is further transported between the card conveyor belts BE3 and BE4, where predetermined card data is written by the magnetic write head FHD2, and the card data is read by the magnetic read head HD1 to read the predetermined card data. A determination is made as to whether or not it has been written correctly. If the data is not written correctly, the motor M OT 1 is rotated in the reverse direction to write the predetermined data on the card again, and then the motor is rotated in the normal direction again to read the card data. If the card data is not correctly written even after several attempts, the motor MOTI is reversed and the card is collected into the collection box.

When the card data is correctly written to the card, the card is ejected from the card ejection port.

The operation described above was an example of issuing a card by simply writing card data onto a magnetic card, but recently, a so-called security card issuing function is required to prevent card forgery or tampering.

A so-called security card is a card that has security data written in advance to be used as a key when encrypting card data in a predetermined area of a magnetic cart, or a card that has encrypted card data written to this card. The security is extremely high because the data is encrypted and the card cannot be counterfeited by copying only the card data.

(C) Problems to be Solved by the Invention When such a security card is issued using a general card issuing machine as shown in FIG. 1, there are various inconveniences described below.

In other words, when writing cart data to the card, it is necessary to encrypt it using security data.
Security data must be read from the card in advance. However, while the reading head is located on the card discharge port side (downstream side) of the card transport path, the write head is located on the card stocker side (upstream side) of the card transport path.

Therefore, the card is first transported to the reading head part on the card ejection port side, and the security data is read.
Cart data to be written must be encrypted based on this security data, and the card must be transported in the opposite direction to write the encrypted card data. In this way, each time a card is issued, the card must be conveyed in forward and reverse directions; therefore, (1) the card issuance process takes a long time;

■The life of the mechanical parts of the device will be shortened.

■Since the card processing time is long, the power consumption of the entire device increases.

There was a problem.

For example, if a dedicated mechanism is provided to read security data from the card, the above problem will be resolved.
This creates new problems such as increased size and increased costs.

This invention was made by focusing on such conventional problems, and takes advantage of the fact that the security data per 10 tons of security cards loaded into a card stocker is usually the same. The purpose of the present invention is to solve the above-mentioned problems by predicting the above and performing card issuance processing.

(Means for Solving Problem d1) The card issuing device of the present invention includes a card 1 general transport means for transporting a card, on which security data has been written in advance, drawn out from a card stocker, along a transport path; a write head provided on the card stocker side to write card data on the card; a read head provided on the card ejection port side of the conveyance path to read the security data and the card data from the card; a memory for temporarily storing read security data; a card data write control means for encrypting card data to be written to the card with the contents of the memory and supplying a signal of the encrypted card data to the write head; The present invention is characterized by comprising a security data coincidence determination means for determining coincidence between the security data read from the card to be issued and the contents of the memory.

(e) Function In the card issuing device of the present invention, the card transport means transports the card, on which security data is written in advance, taken out from the card stocker, along the transport path. The write throat is provided on the card stocker side of the transport path, and the reading head is provided on the card discharge port side of the transport path. Further, the memory temporarily stores the security data read from the card during the previous card issuance as security data to be used in the current card issuance attempt. The card data write control means encrypts the card data to be written on the card using the security data stored in the memory, and writes the encrypted card data on the card by giving a signal of the encrypted card data to the write head. Furthermore, the security tag matching determination means determines whether or not the prediction of the security data was correct by determining the match between the actual security data read from the card to be issued this time and the predicted security data stored in the memory. confirm.

Generally, the same security data is written to the security card every 10 cards, so the cards loaded in the cart stocker usually have the same security data. Therefore, with the above configuration, the security data issued last time is temporarily stored in the memory, and when the card is issued this time, the card data is encrypted and written without reading the security data from the card in advance, and later the actual security data of the card is Since the data is checked, if the encrypted card data is correctly written and the security data prediction is correct, card issuance can be completed by simply transporting the card in the normal direction.

(fl Embodiment The structure of the mechanical part of the card issuing device applied to the embodiment will be explained using FIG. 1 again.

In FIG. 1, BEI-BE4 is a card transport heald that constitutes a card transport path, and a card transport motor MOT
1. When the motor MOT1 rotates normally, the card is transported from the card stocker side to the card discharge port side. If the card feeding clutch CLI is turned on while the motor MOTI is rotating normally, the card conveying bell 1-BE
A card is taken out from the card stocker between I-BE2 and conveyed between card transport bells I-BE3-BE4. In the figure, PT5 is a card ejection detection sensor, PT
3 and PT2 are write timing sensors by the magnetic write head HD2, and PTI is a card release detection sensor. If there is a card between the card transport bells hBE3 and BE4 and the card collection clutch CL2 is turned on while the motor MOT1 is rotating in reverse, the card is collected in the collection box. PT4 is a card collection detection sensor.

FIG. 2 shows the structure of the magnetic card applied to this embodiment. A magnetic layer is formed on the entire surface of the card, and stripe data is written at predetermined locations along the card transport direction (a security card is written in advance in the card stocker in FIG. 1). next,
A block diagram of the control section of the device is shown in FIG. In the figure, the CPUI supervises the entire control section. A program to be executed by the CPUI is written in the ROM 2 in advance. The RAM 3 includes an area for storing security data read when the previous card was issued, a working area for encrypting card data to be written to the card, and the like. The interface circuit 4 controls data transmission with the higher-level transmission device. The I10 boat 5 is equipped with various sensors such as the card release detection sensor PTI shown in Fig. 1, two write timing sensors PT2 and PT3, card collection detection sensor PT4 and card feeding detection sensor PT5, and a motor MOTI. , a card feed-out clutch CLI, and a card collection clutch CL2 are connected, respectively. The CPU reads the states of various sensors via the I10 boat 5, performs forward/reverse control of the motor, and also performs clutch control. The card data read/write circuit 6 generates a write signal from the encrypted card data and supplies it to the magnetic write head HD2, and also reproduces the encrypted card data from the read signal from the magnetic read head HDI. The security data reading circuit 7 reproduces security data from the read signal of the magnetic reading head HDI.

Next, FIG. 4 shows the processing procedure of the control section.

First, wait for a command to issue a card from the higher-level transmission device (
nl). If the card issue command is received, the motor MO
Rotate T1 forward, turn on the card feed clutch CLI, and turn off the card collection clutch CL2 (n 2 - n 3
-n4). After that, the card feeding detection sensor °PT5
Wait for PT3 to change from ON to ○FF, and then wait for write timing sensor PT3 to turn ON (n5→n
6). Next, security data a is loaded from a predetermined area of the RAM 3 (nl). The security data read from the card when the card was issued last time or before is written in the specified area of RAM 31, but the memory has not been hacked up and the security data is written when the card is issued for the first time after the power is turned on. If so, it means that random data has been written in the predetermined area of the RAM 3.

Next, the card data is encrypted using the security data loaded from this RAM as an encryption key, and the encrypted card data is output to the card data read/write circuit 6. As a result, the encrypted card data C is written in the cart (n8). Thereafter, the card is further conveyed, and the card data read/write circuit 6 reads the encrypted card data d read by the magnetic reading head MDI from the card league read/write circuit 6 (
n9). Further, the security data reading circuit 7 reads the security data b read by the head HDI (nlo). Thereafter, it is determined whether the security data a loaded from the RAM matches the security data b actually read from the card (n11). If they match, it is further determined whether the encrypted card data C written on the card and the encrypted card data d read from the card match (n12). If this matches, the card release detection sensor PTI turns ON and then turns ON.
By turning FF, it is detected that the card is ejected from the ejection port, and the motor MOTI is turned off (n 13-n
14-zt 15) 6 After that, a command indicating that card issuance has been completed is sent to the higher-level transmission device (n
16).

If it is determined in step rr12 that the encrypted card data d read from the card is not the predetermined data,
Write the encrypted card data again. That is, first, the number of retries (initially set to O) is incremented (n12 → n17), and this number of retries becomes 2.
If it does not exceed r+1, reverse the motor MOT1.
8→n 23), and waits for the write timing sensor PT2 to be turned on (n 24.). When PT2 is turned ON, encrypted card data is written to the card while the card is being conveyed in the reverse direction (n25). Then motor M
Rotate OT1 forward and read card data (n26-n
9). After that, similar processing is performed.

3 If the number of retries exceeds 2 as determined in step n18, the motor MOT1 is reversed, the card collection clutch CL2 is turned on, and the card collection detection sensor PT4 is activated.
Wait for the change from N to OFF (n19→n2O-n21
). Thereafter, a new card is taken out from the card stocker and the issuing process is performed from the beginning (n2-...).

If the security data read from the card is different from the expected security data in step nil, the security data in the RAM is changed to the security data actually read from the card in step nlO (nil -n22). after that,
While transporting the card in reverse, the card data is encrypted using the changed security data as the encryption key, and the encrypted data is written (n23-n24→n2
5→...).

As described above, the security data used for the next card issuance is temporarily stored in the memory, and when writing the card data, the card data is encrypted using the security data in the memory 4 as the encryption key. , write the encrypted card data,
Verify that the card data matches the security data prediction when reading it.

(g+ Effect of the invention According to this invention, encrypted card data can be written before reading the security data written in advance on the card. Normally, necessary data can be written by simply transporting the card in normal rotation. A written card can be issued.Therefore, the card issuing processing time is shortened, the life of the mechanical part of the device is extended, and the power consumption per card issuing processing is reduced. Additionally, compared to a device that requires a special mechanism to read security data from the card in advance, the device can be configured with a simple mechanism similar to conventional ones, which has the effect of not increasing the overall size of the device. .
