[0007]

By the way, in recent years, the mutual entry of railway companies has been performed, and if the encoding system of the card used by each railway company of the mutual entry is different, it is difficult to use the card. The passenger (passenger) cannot carry out automatic ticket gates unless he / she possesses a card for each railway company.

To solve such inconveniences, it is conceivable to install a main body for each encoding system in the ticket gate, but this increases the equipment cost and requires an extra installation space, which is not practical.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an automatic ticket gate that enables automatic ticket gates even when the card encoding system is different.

[0010]

In order to achieve the above object, an automatic ticket gate according to the present invention uses data recorded on a track provided on a magnetic card so as to be parallel to the direction of insertion into a main body. In an automatic ticket gate that reads via a magnetic head and performs an automatic ticket gate based on the result of arithmetic processing of the read data, of the data recorded in the preamble data portion of the track, a portion on the insertion direction side Extraction means for extracting a fixed amount of data, and when the data extracted by the extraction means is related to a predetermined number of tracks or more, it is determined that the magnetic card related to the extracted data is of the parallel duplex system, If there is a track in the extracted data with a lower data density than the data density of the other tracks, the magnetic card of the extracted data is non-duplex. Determines that the system, when the other magnetic card according to the extracted data is characterized by having a determining means and a series duplex scheme.

[0011]

In the above arrangement, when the data extracted by the extracting means is related to a predetermined number of tracks or more, the judging means judges that the magnetic card relating to the extracted data is of the parallel duplex system. If there is a track with a data density lower than the data density of other tracks in the extracted data, it is determined that the magnetic card of the extracted data is of a non-duplex type, otherwise,
The magnetic card according to the extracted data is determined to be of the serial duplex system.

Various devices such as sensors S, S... And a driver of the motor M are connected via the connector 1, but are omitted here.

Before describing the control operation of the present embodiment, a method of determining the encoding method of the card C will be described with reference to the explanatory diagram of FIG.

First, the judgment is made based on the fact that the card C of the parallel duplex system has a larger number of tracks than the serial duplex system and the non-duplex system.

In the card C of the non-duplex type, the data density (bit density) of one track is lower than that of the other tracks (in the case of FIG. 5C, the track C is composed of the tracks A and B).
Half of that).

A serial duplex card is determined based on the fact that it is neither a parallel duplex system nor a non-duplex system.

[0023] The above determination is (in the case of card series duplexing scheme, the preamble data portion d ₁ in the insertion direction side) preamble data portion d ₁ of the card C reads data is performed based on the data.

However, this determination cannot be made immediately after the reading of the data of the preamble data section d ₁ is started, and cannot be made after the reading is completed.

The reason is that the data writing position of each of the tracks A to G has a maximum variation of 2 mm.
Even if the reading of the preamble data section d ₁ is started on the track A, the reading of the track B may not be started yet, and the preamble data section d of the track A may be further read.
Even if completed the reading of the _first data starts reading the main data portion d _3, reading of data of preamble data portion d ₁ of the track B is because it may not ended. Therefore, in the automatic ticket gate machine according to the present embodiment, as described below, the preamble data portion d ₁ after reading a predetermined amount to determine the encoding of the card C.

Next, the control operation of the automatic ticket gate according to the present embodiment will be described with reference to the flowchart of FIG. Now, suppose that the card C is inserted into the insertion slot 1 (step 10).
0 affirmation. Hereinafter, the steps and S), the card C by the conveying path 6, is sent to the read head H _1, the synchronization data is read first synchronous data portion d _1. This allows the CPU
Reference numeral 11 denotes the posture of reading preamble data or main data to be read next (S102).

The card C, when it is further transported by the transport path 6, the head H ₁ reading starts reading of the preamble data (S104: Yes). Then, when the reading is performed by a predetermined amount, it is determined how many tracks of data have been read.

If the number of tracks is determined to be five or more in this determination, the inserted card C is determined to be a parallel duplicated card (Yes in S106, Yes in S108).

When it is determined that the number of tracks is less than five (No at S108), the card C is a serial duplex card or a non-duplex card.

As for the non-duplex card, since one of the tracks has a low data density, if any of the read data has a low density, the card is determined to be a non-duplex card (S110). If affirmative, S112), if there is no such low-density data, the card is determined to be a serial duplicated card (S110 negative, S114).

As described above, the automatic ticket gate according to the present embodiment can determine the encoding method with the card C when the predetermined amount of preamble data has been read. Since the data processing of the main data can be performed according to the system, it is possible to process cards with different encoding systems with one automatic ticket gate.

The number of tracks of the card C shown in FIG. 5 is merely an example, and it is needless to say that the number of tracks may be larger or at least better.

[0033]

According to the automatic ticket gate of the present invention, of the data recorded in the preamble data portion of the track,
Extracting means for extracting a predetermined amount of data in the insertion direction, and when the data extracted by the extracting means is related to a predetermined number of tracks or more, the magnetic card relating to the extracted data is a parallel duplex system. When it is determined that there is a track having a lower data density than the data density of other tracks in the extracted data, it is determined that the magnetic card related to the extracted data is a non-duplex system, At other times, the magnetic card relating to the extracted data comprises determination means for determining the serial duplex system, so that the reading of the main data portion and the data processing are made compatible with the encoding system of the inserted card. It becomes possible. Therefore, one automatic ticket gate can process cards with different encoding systems.
