Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a toll collection method for collecting tolls by reading and determining magnetic recording information recorded on a magnetic recording medium.

(Prior Art) Conventionally, bank cards, railway tickets, etc. have been known as magnetic card-type automated tickets (recording media), but recently, punch card-type toll road passes, etc., have also been used. A magnetic card type system is being considered.

(Problem to be solved by the invention) However, conventionally used magnetic card-type automated tickets are weak against external magnetic fields due to the low magnetic coercive force of the magnetic recording layer, and recorded information is demagnetized by external magnetic fields. The problem is that it is often overlooked. When such an automated ticket is used as a toll road ticket, the ticket issuing machine at the road entrance gate magnetically records entrance information such as the entrance interchange number and vehicle model number, and the ticket is handed to the passing vehicle. There is a risk that the magnetic recording may be demagnetized or demagnetized by being fixed with magnetic thumbtacks in the vehicle, being affected by the vehicle's magnetic field, or even being broken.

Therefore, it has been proposed that the magnetic recording layer of such a magnetic card-type pass be formed of a material with high coercive force that is resistant to external magnetic fields to prevent the magnetic recording from being demagnetized by the external magnetic field. However, even if this is done, it is not possible to completely prevent magnetic recording from being demagnetized by an external magnetic field, and recording defects may occur during magnetic recording.
For this reason, even if an attempt is made to calculate the toll by reading the magnetically recorded information on the pass received from the vehicle at the exit gate using a pass ticket verification machine, the read information is unreliable and may cause various troubles. Ta. Similarly, if the recorded data on a pass ticket that has been used once is lost, there is a risk that it will be reused, which may cause trouble.

The present invention has been made in view of the above-mentioned points, and its purpose is to realize that most of the demagnetization of magnetically recorded information occurs partially;
Furthermore, we focused on the fact that recording defects that occur during magnetic recording are only a few bits, unless they are caused by equipment failure, and they almost never occur repeatedly, and we recorded the same information multiple times on the magnetic recording layer. The present invention aims to provide a fee collection method that enables highly reliable reading/discrimination of magnetically recorded information and allows recording media to withstand long-term storage.

[Structure of the Invention] (Means for Solving the Problems) In order to solve the above problems, the present invention, as a first invention, magnetically stores entrance information on a rectangular recording medium provided with a magnetic recording layer at the entrance of a paid facility. In the method of collecting fees by recording and reading entrance information from the recording medium and identifying it, an entrance information code is magnetically recorded and issued multiple times on the magnetic recording layer of the recording medium at the entrance, and the information is read at the exit. After calculating the fare based on the entrance information that has been correctly read from among the information recorded multiple times, the exit information is written multiple times on the magnetic recording layer of the recording medium, and the exit information is further printed and stored. It is characterized by:

A second invention is a method of magnetically recording entrance information on a rectangular recording medium provided with a magnetic recording layer at the entrance of a paid facility, and collecting fees by reading and determining the entrance information from the recording medium at the exit. The entrance information code is magnetically recorded and issued multiple times on the magnetic recording layer of the recording medium, the information is read at the exit, and the fee is calculated based on the entrance information that is correctly read from among the information recorded multiple times. After deleting all of the multiple entrance information magnetically recorded at the entrance and writing the correctly read entrance information and the calculation result information once on the magnetic recording layer of the recording medium,
The present invention is characterized in that the exit information is written multiple times on the magnetic recording layer of the recording medium, and the exit information is further printed and stored.

(Function) That is, by having the above configuration, the present invention magnetically records and issues an entrance information code multiple times on the magnetic recording layer of a recording medium at the entrance of a toll road, reads the information at the exit, and confirms that the code is correctly read. Fees are calculated based on entrance information. Then, the exit information is written multiple times on the magnetic recording layer of the recording medium, and the exit information is printed and stored. Preferably, the read entrance information and the calculation result information are written in the magnetic recording layer of the recording medium.

(Example) The present invention will be described below based on an example shown in FIGS. 1 to 3. Figure 1 shows a magnetic card-type toll road pass, in which 1 is a rectangular piece of paper made of high-quality paper, and 2 is provided on one side of the surface of this piece of paper 1 along the longitudinal direction of the piece of paper. This magnetic recording layer 2 is a striped magnetic recording layer.
is a magnetic material with high coercive force (e.g. BaO−
6Fe ₂ O ₃ ) on the surface of a piece of paper 1. In addition to the magnetic recording layer 2, the surface of this pass has a printed record of information for each entrance and exit, including a printed recording section such as an attendant number, serial number, vehicle model number, interchange number, time, month, and date. Part 3 is provided, and the name of the interchange where the pass issuance, notes, etc. are printed in the margin.

This ticket is stored in the magnetic recording layer 2 by a ticket issuing machine at the entrance gate of the interchange, including entrance information such as the staff number, serial number, vehicle model number, etc.
Information such as the interchange number, time, date, etc. is magnetically recorded, and the same information as the magnetic information recorded on the magnetic recording layer 2 is printed and handed to passing vehicles. Magnetic recording of the above-mentioned entrance information is carried out, for example, by the FM recording method as follows.

That is, FIG. 2 shows the format of the magnetic recording recorded on the magnetic recording layer 2 of the pass.
The magnetic recording device (recording head) built into the ticket issuing machine is installed in the middle of the conveyance path that transports the ticket from the ticket storage section to the ticket issuing port (retrieval port). ), then the start signal, the entry information signal starting from the first character, the end signal, and the BCC signal are sequentially recorded to perform the first magnetic recording, and then the start signal is recorded. By repeatedly recording the
After the third and final magnetic recording is completed, a timing signal is recorded to the end of the magnetic recording layer 2, and the magnetic recording is completed. That is, three blocks of entrance information are magnetically recorded at the entrance interchange.

In the ticket verification machine at the exit interchange, all the magnetic information magnetically recorded on the ticket is read by a reading head, and a discrimination control circuit (not shown) checks whether the magnetic information in each block has been read correctly. The toll is calculated and displayed using the magnetic information of the correctly read block. Then, the write head magnetically records one block of the entry information normally read by the read head. Furthermore, exit information at the exit interchange, i.e., attendant number, serial number, vehicle model number, interchange number, time,
It is configured so that two blocks of information such as month and date and the toll calculated by the discrimination control circuit are written.

In addition, Fig. 3 shows the record number of the FM system, and the timing signals mentioned above are all “0” signals, and the start signal and end signal are all “1” signals.
It is considered to be a signal.

Therefore, at the entrance interchange, the same entrance information code is magnetically recorded three times on the magnetic recording layer 2, and the entrance information is printed and recorded on the information printing recording section 3, and the pass ticket handed to the passing vehicle is transferred to the exit interface. It will be handed over to the toll collector at Chienji. Then, when the ticket collector inserts the ticket into the ticket verification machine, the entrance information magnetically recorded on the magnetic recording layer 2 is read. The entrance information read by the magnetic recording information reading device of this ticket verification machine is sent to a data processing device, where it is checked whether it has all the necessary entrance information. If the entered entrance information is complete, the read information signal is sent to the fare meter and recorded in the data processing device.

However, some of the same information magnetically recorded on the magnetic recording layer 2 is partially demagnetized due to the influence of an external magnetic field, or has a partially recorded defective portion. Therefore, if the first recorded information is incomplete, a second reading of the recorded information is performed following the first information reading, and if that information is also incomplete, the next The recorded information is read three times, and the complete one of the entrance information magnetically recorded three times is picked up, and the information is recorded in the data processing device as the read entrance information and is sent to the charge calculator. The toll amount calculated by the toll calculator is displayed on the toll display, and the toll amount is collected from passing vehicles by the attendant.

The pass ticket whose entrance information has been read in this way has the entrance information, exit information, toll information, and other necessary information that were normally read by the ticket verification machine stored in the magnetic recording layer 2 (previous entrance information record). (is erased), and the exit information is printed and recorded in the information printing and recording section 3 and stored as a data card.

Therefore, since the exit information is recorded multiple times on the used ticket once it has passed through the exit, the possibility of the exit information being lost is extremely low and there is no risk of unauthorized use. Also, since the exit information is not lost, it can be effectively used as a data card. In addition, the pass ticket stored as a data card can be prevented from being reused, and even after the pass ticket has been used, it is possible to check whether the pass ticket was used illegally or whether the fare calculation was performed correctly.

In addition, in the above embodiment, a method for determining magnetic information on automated tickets used as toll road passes has been described, but the present invention is applicable to reading and determining magnetic information recorded on magnetic bank cards, railway tickets, etc. The magnetic recording method is not limited to the FM method, but may also be the NRZ or PM method.

[Effects of the Invention] As explained above, according to the present invention, highly reliable information processing can be performed with less influence from external magnetic fields and handling, and moreover, the recording medium can be stored as a data card. It has excellent effects.
