Abstract

PURPOSE:To automatically check the tickets by communicating with cards of plural communication forms through a single main body with use of plural transmitters corresponding to the types of signals used by the cards. CONSTITUTION:The transmitters T1 and T2 transmit the prescribed call signals, i.e., the polling command signals to the cards C1 and C2 from a main body G via the antennas a1 and a2 alternately and at each prescribed time like a widely known non-contact automatic ticket checking machine. At the same time, the communication started with one of both cards C1 and C2 is continued and the entering/leaving data, i.e., the data on the station names, the effective dates, etc., can be transmitted and received. Then the data are transferred between both cards C1 and C2 of different communication forms, and the communication is carried on between both cards until a series of ticket checking processing are completed. Thus the crosstalk can be effectively prevented.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a contactless automatic ticket gate, and more particularly to a contactless automatic ticket gate which can communicate with a plurality of contactless cards having different communication modes.

[0002]

2. Description of the Related Art Currently, the automatic ticket gates that are widely used are automatic ticket gates by inserting a ticket or a commuter ticket into the main body of the automatic ticket gate (hereinafter, the main body of the contactless automatic ticket gate) Is configured to be performed. However, this insertion-type automatic ticket gate has a problem that the commuter ticket user has to insert and remove the commuter ticket from the commuter ticket compartment each time the commuter ticket user passes through the ticket gate.

Therefore, in order to solve such a problem, a non-contact type card (hereinafter referred to as a card) of an IC card having a communication function is used as the commuter pass, and the commuter pass is contactless with the card. A contactless automatic ticket gate has been proposed that can exchange data and perform automatic ticket wicket without inserting a commuter pass into the main body (for example, JP-A-1-246).
687).

[0004]

When a non-contact type automatic ticket gate is adopted, there is a concern that the communication format between the main body and the card differs between railway companies.

For example, it is conceivable that the A railway company uses the 200 KHz medium wave and the B railway company uses the 400 KHz medium wave. Also, at the C railway company, 2.
The microwave of 45 GHz is used, and in addition, the D railway company differs from the microwave of the C railway company in 2.44 GHz.
It is also conceivable that the microwave of

No matter what communication mode is adopted, if the user (passenger) uses only one railway company's route, since the communication mode is single, he / she must carry a card for that railway company. Therefore, the following problems do not occur.

[0007] At present, the transit boarding is generally carried out. At this time, if the communication form is different for each railway company as described above, one card C as a communication commuter pass corresponds to a plurality of communication forms. Although it is possible to have a function that can be done, this is not possible in implementation, so that each communication mode, that is, each route has a plurality of cards.

Since it is inconvenient for the user to carry a plurality of cards, in order to eliminate such inconvenience, it is necessary to install a plurality of types of main bodies for each communication mode at the ticket gate. Can also be considered.

However, it is not realistic to install a plurality of types of main bodies because not only a large installation space is required but also the cost is increased.

Therefore, an object of the present invention is to provide a non-contact type automatic ticket gate which can deal with contact commuter pass type cards having different communication modes.

[0011]

In order to achieve the above object, a contactless automatic ticket gate according to the present invention performs data transfer between a transmitter and a card provided in the main body to perform an automatic ticket gate. In the non-contact type automatic ticket gate, the transmitter is a plurality of transmitters according to the types of signals used in the card. Further, the plurality of transmitters are alternately driven in sequence, and once the communication with the card is started, the transmitter continues the communication until a predetermined series of ticket gate processing is completed. .

[0012]

In the above structure, the main body has a plurality of transmitters, and data is exchanged with cards having different communication modes. Once the communication with the card is made, the communication with the card is continued until the series of ticket processing is completed, and the interference is effectively prevented.

As described above, the non-contact type automatic ticket gate according to this embodiment is provided with the transmitters T1 and T2, so that it is possible to process two cards C1 and C2 having different communication modes, and different for each railway company. Even if the communication form is adopted, it is possible to make a contact ticket gate with a single main body.

Although two transmitters are provided in the above-mentioned embodiment, when the card used in the main body G is a card having three or more communication modes, three transmitters corresponding to the three or more communication modes are used. More than one transmitter is used.

[0029]

Since the non-contact type automatic ticket gate according to the present invention has a plurality of transmitters according to the types of signals used in the card, a single main body automatically communicates with a plurality of communication mode cards. The ticket gate can be performed, which is particularly convenient for connecting passengers on routes with different communication modes.

Further, the plurality of transmitters are alternately driven in sequence, and once the communication with the card is started, the transmitter continues the communication until a predetermined series of ticket gate processing is completed, Interference can be effectively prevented and automatic ticket gates can be performed.
