BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a contactless pass gate system that wirelessly transmits and receives data for determining passability between a medium such as a commuter pass and a gate such as an automatic ticket gate.

0002

[Prior Art] Passgate systems, which are applied to ticket gate processing in stations and entry/exit management in companies, transmit and receive data wirelessly between media such as commuter passes and gates such as automatic ticket gates. A contactless passgate system has been proposed. In this contactless passgate system, a medium possessed by the user must be equipped with a data transmission/reception function, and it is considered that an IC card is used as a component of such a medium. By wirelessly transmitting and receiving data between the medium and the gate in this way, it is possible to simplify the handling of the medium when the user passes through the gate.

0003

[Problem to be Solved by the Invention] However, since the IC card that constitutes the medium is expensive, it is necessary to update the expiration date etc. on a single medium so that it can be used repeatedly. For issued commuter passes, it is not possible to indicate the riding section, expiration date, etc. by printing on the outside of the medium. For this reason, the user cannot know the expiration date of the medium or the balance of the usage amount during use, and does not become aware of these until the expiration date has passed or the balance has been exhausted, and the user is judged to be impassable at the gate. There was a problem that I couldn't do it. Furthermore, when a gate is determined to be impassable, the gate cannot be used for a predetermined period of time, which poses a problem in that smooth passage of users through the gate is hindered.

[0004] An object of the present invention is to display data stored on a medium, such as the expiration date of the medium and the balance of usage amount, at the gate so that the user can recognize these contents every time the user passes through the gate. An object of the present invention is to provide a non-contact pass gate system that prevents the occurrence of a state of impassability due to expiration of an expiration date or insufficient balance, and enables users to smoothly pass through a gate.

[0005]

[Means for Solving the Problems] A non-contact pass gate system of the present invention wirelessly transmits and receives data between a medium storing data for determining passability and a gate that executes a passability determination based on the data. The contactless pass gate system is characterized in that the gate is provided with display means for displaying part or all of the data transmitted from the medium.

[0006] Also, the gate is an automatic ticket gate installed in a station.

[0007]

[Operation] In this invention, part or all of the data transmitted from the medium for determining passability is displayed at the gate. This data for determining passability includes, for example, data representing the boarding section and expiration date of the commuter pass that makes up the automatic ticket gate processing system, and these data transmitted from the medium can be displayed at the gate. This allows the user to recognize the content of the data stored on the medium.

FIG. 3 is a flowchart showing the processing procedure of the automatic ticket gate and the control section of the IC card. When the IC card 21, which is a commuter pass, detects that it has been presented within the communicable area of the automatic ticket gate 1 by the user, it transmits recognition data including its own ID code (n11). A reading signal is transmitted from the automatic ticket gate 1 at regular time intervals, and the IC card 21 receives this reading signal and knows that the IC card 21 has entered the communicable area. In addition, IC card 21
If the IC card 21 is to be supplied with power by a power carrier wave transmitted from the automatic ticket gate 1, the processing procedure may be programmed so that the recognition data is transmitted after the IC card 21 is activated. When the automatic ticket gate 1 receives this recognition data, it transmits confirmation data to that effect (n1, n2), and the IC card 21 that received the confirmation data
transmits the passability determination data stored in the storage unit 23 (n12, n13).

The automatic ticket gate 1 receives data for determining passability transmitted from the IC card 21, and stores the data in the storage unit 5.
After temporarily storing the data, the predetermined data is output to the display controller 10 as display data (n3 to n5). As shown in FIG. 4, memory areas MA1 to MA6 of the storage unit 5 connected to the control unit 4 of the automatic ticket gate 1 store the boarding section, expiration date, prepaid balance, gender, start date and time of use, and user name, respectively. assigned to a storage area. Among these, memory areas MA1 to MA4 are used as display data to be displayed on the display 3. More specifically, when a user bids for a commuter pass when entering the station, the display 3 shows the boarding section and expiration date stored in the memory areas MA1 and MA2, as shown in FIG. 5(A). When bidding on a prepaid card, the balance of the usage amount stored in the memory area MA3 is displayed as shown in FIG. 5(B). In addition, when the user exits the station and the prepaid card is issued, the display 3 displays a calculation to calculate the difference between the balance at the time of ticket inspection and the amount used this time, as shown in Figure 5(C).
