DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a non-contact automatic ticket gate, and more particularly to a non-contact automatic ticket gate capable of excellently communicating with a non-contact card.

[0002]

2. Description of the Related Art For example, as disclosed in Japanese Patent Application Laid-Open No. 1-246687, data is transmitted and received between an automatic ticket gate main body and a commuter pass in a non-contact manner, and the data is periodically transmitted to the automatic ticket gate main body. 2. Description of the Related Art A non-contact automatic ticket gate has been proposed that can perform automatic ticket gate insertion without inserting a ticket. This non-contact automatic ticket gate has a feature that it is not necessary to insert tickets such as a commuter pass into the main body of the non-contact automatic ticket gate, thereby improving the convenience of the user.

[0003]

By the way, in the case of a contactless automatic ticket gate, a user uses a contactless card (hereinafter, referred to as "card") as a main body of the contactless automatic ticket gate (hereinafter, referred to as "body"). ) Must be held precisely over the transmitter's communication range. If the hand is held up incorrectly, for example, if the card repeatedly enters and exits the communication area, or if it does not enter the communication area at all, communication will be poor and entry and exit will be prohibited. I will.

[0004] In order to prevent such inconvenience, it is conceivable to increase the output of the transmitter to increase the communication range. However, if the communication range is too wide, communication with a card of a user of an adjacent main body may occur. A new problem occurs, such as generation of noise between the signal transmitted from the transmitter of the adjacent main body.

The present invention has been made in order to solve the above-mentioned drawbacks, and an object of the present invention is to provide a non-contact automatic ticket gate that enables a user to reliably hold a card over a communication range of a transmitter. To provide.

[0006]

To achieve the above object, a non-contact automatic ticket gate according to the present invention comprises a wireless transmitter and a non-contact card provided in a non-contact automatic ticket gate main body. In a non-contact automatic ticket gate that performs data exchange in a non-contact manner between the non-contact type and the automatic ticket gate, a stereoscopic image generating unit that generates a stereoscopic image in a communication range with the non-contact type card in the transmitter is provided. It is characterized by:

Further, the transmitter is characterized in that it starts communication when a card is inserted in the stereoscopic image.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a non-contact automatic ticket gate according to an embodiment, and shows a use state of the main body G, that is, a ticket gate P at an entrance side of a gate passage P of a housing H of the main body G. There is provided a display unit 2 for displaying to the user whether or not the vehicle can pass through. In addition, an antenna a connected to a transmitter, which will be described later, for transmitting and receiving data to and from a card C carried by a user by wireless communication faces the upper part of the front part of the housing H.

A three-dimensional image generator 3 is provided on the sensor mounting arm 2 located above the antenna a.
It is configured to generate a stereoscopic image X indicating a communication range in a communication range of the transmitter, that is, a predetermined range above the antenna a. The three-dimensional image generator 3 includes a housing H
In any case, the stereoscopic image X is positioned within the communication range of the transmitter. As the three-dimensional image generator 3, a device capable of reproducing a known three-dimensional image can be employed. For example, a stereoscopic image generator that can recognize the stereoscopic image X outside the lens (on the user side) as shown in Japanese Patent Application Laid-Open No. 59-115691, etc. can be adopted.

S, S... Are photoelectric type human detectors for detecting the entry of a user into the ticket gate passage P, the exit from the ticket gate passage P, or the passage thereof. It is attached to the arm 2. Further, a speaker 5 for broadcasting predetermined guidance to a user is attached to a side surface of the housing H.

Reference numeral 6 denotes a controller that controls the operation of the main body G, and is configured using a microcomputer. The controller 6 is connected to a transmitter T for transmitting and receiving data to and from the card C.

The transmitter T is provided with a card C from the main body via an antenna a, similarly to a known contactless automatic ticket gate.
Has a function of transmitting a transmission signal modulated with data such as a station name and a date on the same day, receiving a reflection signal reflected by the card C, and demodulating data of a boarding section and the like transmitted from the card C. doing.

FIG. 2 is a block diagram showing the electrical configuration. To explain from the main body G side, the controller 6 drives the door D in addition to the connection of the transmitter T having the antenna a. The door drive unit 7 to be controlled and the above-described stereoscopic image generator 3 are connected. The controller 6
Are connected to a sensor amplifier or the like for inputting signals from the human detectors S, S..., But are omitted here.

The card C has a receiving antenna 10a and a reflecting antenna 10b for generating a reflected signal by phase-modulating data transmitted from the card C to the main body G, similarly to a normal IC card having a wireless communication function. , Receiving antenna 1
0a, a CPU 11 having a memory for storing data from the main body G and a memory for storing data (card data) of a boarding section and the like.
A phase modulator 13 for modulating the subcarrier from the CPU 12 with the card data to modulate the phase of the reflected signal;
A battery E for driving the card C is provided.

In the above configuration, when the card C is held over the stereoscopic image X in the communication range, the transmission signal transmitted from the antenna a is received by the receiving antenna 10a. Then, from the received signal, transmission data from the main body G side is extracted by the reception unit 11 including a detection circuit, a demodulation circuit, and the like, and is stored in the memory of the CPU 12.

The CPU 12 generates a subcarrier of, for example, 500 KHz, which is sufficiently lower than the frequency of the main carrier (for example, 2.45 GHz) when generating the transmission signal of the main body G, and performs a multiplication circuit (see FIG. (Not shown) and a card data (digital signal) to be sent to the main body G by a multiplication circuit (not shown) of the phase modulation unit 13.
Output to Therefore, a signal in which the subcarrier is modulated with the card data is generated from the multiplication circuit.

The generated signal is transmitted through a phase modulation circuit (not shown) of the phase modulation section 13 to the reflection antenna 10b.
Power is supplied to Therefore, when the main carrier wave transmitted in a time-division manner from the antenna a of the transmitter T hits the reflection antenna 10b and is reflected, the phase is just modulated with the card data.

When the antenna a of the transmitter T receives the reflection signal reflected by the reflection antenna 10b, the reception circuit (not shown) performs detection processing, filter processing, and amplification processing to extract data from the card C side. Then, the extracted card data is sent to the controller 6 of the main body G and used for the automatic ticket gate calculation processing.

As a result of the arithmetic processing, when the passage of the ticket gate P can be permitted, the door D is opened (when the main body G is a normally open type), the door D is closed when the passage is not permitted.

As described above, since the card C is held over the three-dimensional image X indicating the communication range, it is possible to effectively prevent the door D from being closed due to communication failure, and to improve the ticket gate processing efficiency.

Further, a detector such as a photosensor for detecting an object in the three-dimensional image generated as a feature of the three-dimensional image generator 3 is provided, and the transmitter T can be driven and controlled based on the detection signal. . Therefore, when the transmitter T is driven when the card C is detected in the stereoscopic image X, the power saving effect can be improved and the noise to other main bodies can be reduced.
