Typical examples of pipe riding include the types shown in FIGS. 2 and 3. In other words, in the type shown in Figure 2, a passenger riding from station A to station D has a regular ticket (
This is an example in which a commuter pass (P) is used between stations C and D. In addition, the type shown in Figure 3 means that if a passenger who has a commuter pass (P) between stations F and D rides from station A to station D via station C, a regular ticket between stations A and B will be used. (T), and use the above-mentioned commuter pass (
This is an example of using P). In addition, in the above two typical examples, instead of using a regular ticket (T) between A and B stations as described above, another commuter pass (T) valid only between A and B stations is used. This also includes cases where In addition, below,
In the act of riding a smoke pipe, the ticket (T) used for the starting section (between stations A and B in the above example) is called the starting side ticket (T), and the commuter pass (P) used at the station where you get off is called the one for getting off. Commuter ticket (P

As shown in Figure 4B, record the date and time of the current ride in a visible manner. In other words, ■ For a regular ticket (10) that is generally used only for one ride, the boarding date and time is recorded by regular printing, and ■ Generally used many times during the validity period. For the commuter pass (20), the boarding date and time is visually recorded magnetically by converting the magnetic powder (22) provided in the display window (21) into text so that it can be rewritten each time the boarding occurs. be done. In this way,
All tickets, whether regular tickets or commuter passes, have the boarding date and time recorded at the boarding station. Note that, as described above, the magnetically recorded boarding date and time is not erased at the exit station, but remains until the boarding date and time is recorded at the boarding station for the next boarding. In order to perform such visually visible magnetic recording, a visible magnetic recording sheet developed by Ganto Toyama (Japanese Patent Application No. 62-19665) was developed.
It is preferable to have a structure similar to No. 9). Further, it is preferable to magnetically record the current boarding station for the commuter pass (10), and it is also possible to magnetically record the boarding date and time for the regular ticket (1o).

That is, according to the present invention, first, at the ticket gate of the boarding station, the station staff receives and takes the ticket from the passenger and, as in the past, checks whether the border is a valid ticket with no fraud in the valid section. After checking the ticket, if it is determined to be a valid ticket, the boarding date and time are written on it using a writing machine, and then it is returned to the passenger. Next, at the ticket gate of the station where the passenger gets off, the station staff will check whether the commuter pass presented by the passenger is valid, based on the validity period and valid section etc., as before. At the same time, check whether the boarding date and time recorded by the writing machine is on the same day as mentioned above, and even if it is on the same day, check the time from the recorded boarding time to the actual time of getting off. Automatically or manually check whether an abnormally long time has elapsed in between. In this way, if the commuter pass is a valid ticket with no irregularities in its validity period and valid section, the boarding date and time is on the same day, and the actual time of getting off is not long, the station staff will The commuter pass is determined to be a genuine ticket without any act of smoking a pipe, and the passenger is allowed to pass.

In addition, if the boarding date and time is not from the same day, or if a long time has elapsed between the time and the actual time of getting off, it will be determined that there is a suspicion of smoking pipe riding, and the passenger will be notified about the boarding. The system requests the presentation of the start-side ticket actually used at the boarding station, and determines whether or not there is a smoking pipe ride based on the valid section of the start-side ticket and the valid section of the commuter pass for getting off. In this way, if it is determined that there is an act of smoking pipe riding, payment of the insufficient fare is requested. As described above, the method according to the present invention can effectively detect smoking pipe riding by simply recording the date and time of boarding, which proves that the boarding station has passed through the ticket gate. Since the date and time are recorded in a visible manner, it also has a psychological deterrent effect on customers who are planning to smoke pipes.

First, at the ticket gate of A Station, the boarding station, the customer
- Present the starting ticket (T) between stations B, and if the border (T) is a valid ticket, the station staff will write the ticket (T) using a writing machine as shown in Figure 4A or Figure 4B. record the date and time of the ride in a visible manner. Next, at the ticket gate of D Station, which is the station where the customer gets off, the customer attendant presents the commuter pass (P) for getting off between C and D stations and tries to take a bath, but the station staff Check the validity period, valid section, boarding date and time of the commuter pass (P) automatically or manually, or
If the boarding date and time written in P) is other than that day (i.e., it is the same as the record from the last ride), or if it is the same day but a long time has passed,
The customer service person is requested to present the ticket (T) on which the boarding date and time of the day actually used is written at the ticket gate of the boarding station.

In this way, when the customer presents the starting-side ticket (T), the station staff can distinguish between the valid section printed on the starting-side ticket (T) and the valid section of the commuter pass (P) for getting off. By referring to the section actually boarded, customer service can be improved from B to C.
It is possible to discover that the passenger was a smoker passenger who took the train between stations for free.

That is, first, at the ticket gate of A station, which is the boarding station,
When the customer presents the starting ticket (T) between stations A and B, the station staff uses a writing machine to record the boarding date and time on the border (T). Next, the passenger rides from Station A to Station C via Station D, and then passes the commuter pass for getting off between Stations F and D at the ticket gate of Station D.
), but the station staff tries to show this F-D.
Automatically or manually check the validity period, valid section, and boarding date and time of the commuter pass (P) between stations, and check if the boarding date and time written on the commuter pass (P) is other than that day, or if it is on the same day. Even if a long time has passed since the boarding date and time, the customer is requested to present the ticket actually used at the boarding station. In this way, when a passenger presents the starting ticket (T), the station staff can identify the valid section of the border (T), the valid section of the alighting commuter pass (P), and the section in which the passenger actually boarded the train. By referring to
It was discovered that the person serving the customer was a smoke pipe passenger who took the train between B and C stations for free.

In addition, in the above-mentioned procedure for finding smoke pipe passengers, even if the boarding date and time written on the alighting commuter pass (P) is on the same day, if it has been an abnormally long time, it is considered to be smoke pipe riding. For example, in the route configuration shown in Figure 2, a passenger who is judged to be suspicious may be a passenger who boarded the train from C station, which is a station within the valid section of the commuter pass (P), but who boarded the train between C and A stations. This is because, after getting off the train at A station by some method, the passenger may take the above-mentioned smoke pipe ride between A and D stations. Also, in the route configuration shown in Figure 3, a passenger who has boarded the train from C station may board the train between C and A stations, get off at A station by some method, and then take the smoke pipe ride between A and D stations as described above. Since there is a possibility that the person may have committed a crime, it is determined that the person is suspected of being a smoker.
