2. Description of the Related Art In an automatic ticket vending machine, a prepaid card may be used for purchase. A magnetic card is generally used as the prepaid card. For example, when purchasing a ticket, the user first inserts the prepaid card into the card insertion slot. Then, the automatic ticket vending machine takes in the prepaid card by the transport mechanism and transfers it to the internal data reading section. Here, a predetermined magnetic data reading process or the like is performed, a designated ticket is issued, and the data of the prepaid card is rewritten to perform a reduction process. Then, the magnetic card is returned again using the transport mechanism.

However, in such an automatic ticket vending machine, the user needs to insert the prepaid card into the insertion slot each time, which makes the purchase operation troublesome. In addition, the prepaid card may be clogged internally due to, for example, a failure of the transport mechanism of the automatic ticket vending machine.

Therefore, in recent years, automatic ticket vending machines and the like compatible with non-contact cards have been proposed. This is, for example, when a non-contact card type prepaid card is placed in the communication area formed around the automatic ticket vending machine, the automatic ticket vending machine and the prepaid card communicate with each other and perform predetermined processing. Is.

In other words, the user does not need to insert the prepaid card into the automatic ticket vending machine, and can purchase a ticket simply by approaching the automatic ticket vending machine with the prepaid card stored in a bag or the like. Becomes The balance rewriting process of the prepaid card is also performed in a contactless communication state. Further, in such an automatic ticket vending machine corresponding to a non-contact card, there is no need to carry out the operation of transporting the inserted card, and there is an advantage that clogging of the prepaid card can be avoided.

Incidentally, such a device compatible with a contactless card is also applied to ATMs and automatic ticket gates in banks.

[0007]

The conventional non-contact card compatible device has the following problems. When the contactless card is inserted into the communication area of the automatic ticket vending machine or the like, the predetermined communication is started only by this and the ticket issuing operation is performed. Therefore, for example, when another user intrudes into the communication area with a contactless card type prepaid card, there is a problem that an interference situation occurs with the prepaid card owned by the other person, and an erroneous transaction is performed. is there. If a wrong transaction is made,
The remaining amount of money is reduced from the prepaid card of another person.

The problem of erroneous transaction due to such interference also occurs in ATMs and automatic ticket gates for contactless cards. For example, in the transaction of ATM, there is a risk of interference between a plurality of cards owned by the user, as well as interference between another person's card. That is, communication is performed with a card different from the card intended by the user, and transaction processing is performed for another account.

Therefore, an object of the present invention is to provide a non-contact storage medium compatible device capable of preventing erroneous transaction due to interference with other non-contact cards.

[0010]

A non-contact storage medium compatible device according to the present invention transmits transmission data to a non-contact storage medium located within a predetermined communication area and receives received data from the non-contact storage medium. In a non-contact storage medium compatible device, the non-contact storage medium compatible device, comprising:
The transmission / reception unit is characterized in that transmission / reception of transmission data and reception data is performed only with a non-contact storage medium located in a specific limited area.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a non-contact storage medium compatible device according to the present invention will be described by taking a ticket vending machine as an example. FIG. 1A is an external view of the automatic ticket vending machine 1. The automatic ticket vending machine 1 is provided with a coin insertion slot 6 for inserting coins and a bill insertion slot 7 for inserting bills. Further, a purchase button 4 for selecting and purchasing a ticket by pressing it is provided, and the display unit 3 displays the balance of the prepaid card, which is a non-contact medium, the expiration date, and the like. Tickets and banknote coins are discharged from the ticket issuing port / banknote coin return port 8. In this embodiment, the transmitting / receiving unit that communicates with the prepaid card 2 is provided as the mounting table 5.

FIG. 1B shows a partially enlarged view of the mounting table 5. The mounting table 5 has three loop antennas 12 in the left, right, and bottom directions.
Are arranged, and the loop antenna 12 transmits the transmission data to the prepaid card 2. Further, the mounting table 5 is provided with a light-shielding type sensor 14, and this sensor 14 detects the prepaid card when the mounting table 5 puts the prepaid card thereon. Then, based on the detection of the sensor 14, the transmission data is transmitted from the loop antenna 12. That is, in this embodiment, the transmission data is transmitted only when the prepaid card is placed on the mounting table 5.

A limited area 80 of the present invention is formed in the space on the mounting table 5 surrounded by the loop antenna 12.
That is, the transmission data from the loop antenna 12 is transmitted only to the prepaid card located in the limited area 80. Therefore, even when the prepaid card is placed on the mounting table 5 and the transmission data is transmitted, there is no interference with the prepaid card outside the limited area 80.

FIG. 2 shows a block diagram of the hardware structure of the automatic ticket vending machine 1. CPU 23, ROM 22 and RA
M21 is connected via the bus line 20 to form an arithmetic storage unit. The CPU 23 executes a calculation according to a program stored in the ROM 22 and controls each unit.
As the transmission / reception unit, the loop antenna 12 for communicating with the prepaid card 2, the transmission / reception control circuit 26 for controlling transmission / reception, and the interface 27 are provided.

Mechanism control circuit 28 and interface 2
Reference numeral 9 is for controlling a ticket discharging process at the ticket issuing slot / banknote coin return opening 7 (see FIG. 1A) and other mechanisms, which form a mechanism controller. Further, a sensor 14 provided on the mounting table 5 and a control circuit 31 for controlling subsequent processing based on the detection are also connected. Further, a communication control circuit 22 that communicates with the upper CPU is also arranged. Each of these parts is connected by a bus line 40.

A flow chart of the program stored in the ROM 21 is shown in FIG. First, the CPU 23 determines whether or not the prepaid card 2 exists in the limited area 80.
Judgment based on the output from the sensor 14 (step S
2). The sensor 14 constantly irradiates the detection light, and when the prepaid card is placed on the mounting table 5, the detection light is blocked (see FIG. 1B). When the detection light is cut off, a predetermined signal is output from the sensor 14 and taken into the CPU 23 via the control circuit 31 (see FIG. 2).

Next, when the prepaid card is discriminated in step 2, transmission data is transmitted from the loop antenna 12 (step S3). And the mounting table 5
Data is transmitted / received to / from the above prepaid card 2 (step S4). That is, unless the prepaid card 2 is placed on the mounting table 5, the transmission data is not transmitted, and it is possible to save electric power as compared with the method of transmitting the transmission data all the time. The data transmission / reception is performed based on the electromagnetic field coupling generated between the loop antenna 12 and the antenna included in the prepaid card.

It is assumed here that a third party having another prepaid card approaches the vending machine while communicating with the prepaid card on the mounting table 5. However, the limited area 80
Since communication is not performed with a card other than the ID code of the prepaid card located inside, there is no interference with other prepaid cards. Further, before the prepaid card is placed on the mounting table 5, since the transmission data itself is not transmitted from the loop antenna 12, there is no possibility of erroneous transaction.

Based on the data transmission / reception in step S4, the remaining amount of the prepaid card 2 and the expiration date are displayed on the display unit 3 (FIG. 1A) (step S6). Then, according to the selection and pressing of the purchase button 4 (FIG. 1A), balance processing is performed (steps S8 and S10), and a predetermined ticket is issued (step S12).

In this embodiment, the mounting table 5 is provided as the limited area, but as long as the transmission data is transmitted only to the prepaid card located in that area, it is not limited to the trapezoidal shape and has a different form. You may provide as a thing.

In the above embodiment, the mounting table 5 is provided with the light-shielding type sensor 14, but other detecting type sensors may be used. Further, it is possible to constantly transmit the transmission data from the loop antenna 12 without using the sensor. Even in this case, since the transmission data is transmitted only within the limited area 80, it is possible to avoid interference with other prepaid cards not placed on the mounting table 5.

Although the above embodiments have been described by taking an automatic ticket vending machine as an example, the present invention can also be applied to a bank ATM or an automatic ticket gate as long as it is a device corresponding to a contactless card.
