0110 "is shown.

The data check of the record data of the ticket 14 thus constructed will be described with reference to the flowchart of FIG. That is, the CRC calculation is executed based on the ticket data 14b read by the magnetic head 33 and is stored in a predetermined area of the RAM 30 (steps n1 and n2). Convert (step n3).

Next, the CRC code of the check data 14c read from the recording track (the CRC shown in (a) of FIG. 4)
(See code) and the calculated CRC code are compared to determine whether or not they match (step n4). When the CRC codes match (YES in step n4), the A company series The ticket 14 is determined, and then the data of the railway company name (name of the issuing agency of the ticket) is read from the ticket data 14b to determine whether or not the ticket 14 is for the company A (step n5). When it is determined (YES in step n5), the data required for the ticket of the ticket data 14b, that is, whether the boarding section, the fare are valid, or whether the ticket is valid or not is valid. It is determined whether or not (step n6), and if the determination of each of these matters is OK (step n7), it is determined that the ticket 14 inserted in the automatic ticket gate 10 is a valid genuine ticket of the company A, Allow passage through the ticket gates.

When the ticket data is determined to be NO in step n7, for example, the riding section is invalid, the fare is invalid,

Prohibit passage.

Further, the CRC code of the method of the company A calculated in step n4 and the C of the check data 14c are calculated.
When the RC code does not match (NO in step n4 is determined), CRC calculation is executed based on the ticket data 14b, and this is converted by the method of company B according to the above-mentioned equation 2 (step n9) and checked. It is again compared with the CRC code of the data 14c (see the CRC code shown in (b) of FIG. 4) (step n10). If the CRC codes match in this comparison determination (YES determination in step n4), B
When it is determined that the ticket is a company-affiliated ticket 14, the process proceeds to step n8 to execute the processing of the other company's ticket.

On the other hand, in the above determination (step n10),
If they do not match, the ticket data 14b is erroneous, or the reading is defective. In either case, it is determined as an abnormal ticket, and the guide display 17 displays that the ticket is an abnormal ticket, and the ticket gate passage is displayed. The opening / closing door 12 is controlled to be closed so as to prohibit passage.

According to the above-described embodiment, if the CRC code of the company A does not match in the judgment of step n4, the CRC code of the company B is changed to the CRC code of the company B in step n9.
In step 10, since the determination is made again by a different method, the B-company ticket 14 is not determined as an abnormal ticket, but can be determined as another company's ticket and displayed on the guide display 17, and the user understands the reason why it is invalid. Therefore, it is possible to deal with the customer smoothly, provide more detailed guidance to the customer, and improve the service.

In the above-mentioned embodiment, referring to the flow chart of FIG. 6, for the data check of the record data of the ticket 14 when the company A and the company B have mutual access and share one automatic ticket gate 10, for example. explain. Since the data check of the company A is the same as the process shown in FIG. 5, detailed description thereof will be omitted. However, in the determination of step n10 (see step n10 of FIG. 5) in FIG. If the CRC code converted by the company's method and the CRC code read from the ticket 14 (see the CRC code shown in (b) of FIG. 4) are compared again and they match (YES in step n10), B It is determined that the ticket is a company-affiliated ticket 14, and then the data of the electric railway company name (name of the issuing agency of the ticket) is read from the ticket data 14b.
It is determined whether or not the company ticket 14 (step n11), B
When it is determined that the company is a company (YE in step n11)
Next, it is determined whether or not the data required for the ticket of the ticket data 14b, that is, whether the boarding section, the boarding fare is valid, or whether the ticket is valid or not (step n1).
2) If the determination of each of these matters is OK (step n13), the ticket 14 inserted into the automatic ticket gate 10 is B.
The ticket is judged to be valid by the company and allowed to pass through the ticket gate passage.

In step n13 described above, the ticket data 14b
Is determined to be NO, for example, when it is determined that the ticket is not valid as a ticket such as invalid boarding section, invalid fare, or expired, and the ticket is invalid, the guidance display 17
In addition to displaying that the ticket is invalid, the opening / closing door 12 is controlled to be closed so as to prohibit passage through the ticket gate passage.

In step n11 described above, the ticket data 14b
When the data of the electric railway company name (name of the issuing organization of the ticket) read from the company B is not company B, the check data method is the company B series, but the issuing of the ticket 14 is A. Since it is another company other than Company B, it is determined to be another company's ticket (step n8), and the ticket is treated as an invalid ticket whose use is illegal. Prohibition of passage in the passage. In this way, the data check by the automatic ticket gate 10 shared by the companies A and B can be effectively processed as in the previous embodiment.
