Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention includes a first magnetic track that prints visual information such as departure and arrival stations on the front side and records magnetic information for automatic ticket gates on the back side. The present invention relates to useful magnetic cards such as train tickets, designated tickets, and commuter passes (hereinafter referred to as train tickets) that are equipped with a second magnetic track for recording other information.

[Technical background of the invention]

In recent years, automatic ticket gates have become widely used as part of streamlining the ticket gate operations of railways, etc. ! Among the conventional tickets used in automatic ticket gates like this one, when the size is the size of a commuter pass, visual information such as the departure station and arrival station is printed on the front, while the back side is printed with visual information such as the departure station and arrival station. As shown in Figure 1, K
For example, ten magnetic tracks 6 to 6 are provided, of which the middle two tracks e and f are empty tracks], and the remaining eight magnetic tracks 1 to d and ! are provided. Necessary magnetic information such as start date, end date, departure station code, destination station code, transit code, etc. is recorded in ~, and when this magnetic information is read by the automatic ticket gate, / It was designed to determine whether it was possible to get on or off the train.

By the way, these types of commuter pass-sized tickets include those that are purchased once at a time, such as train tickets and reserved seat tickets.
There are things like commuter passes that are purchased continuously,
In the former case, the cancellation/refund process due to reservation cancellation is streamlined, and in the latter case, the issuing process to continuing purchasers is streamlined! ], by recording the information necessary for the cancellation or the information necessary for continued purchase on the empty truck, a single issuing machine can issue multiple tickets. [Problems with the background art] Magnetic track g of such a vehicle roll having the width of a commuter pass
As the material for -j, for example, a magnetic material such as F2O3 designated by the Japan Cybernetics Council was used. This type of magnetic material does not have a very high coercive force of about 300 degrees, so if you leave a magnetic card on a TV, for example, the recorded contents will fade in a short period of time. In particular, if a commuter pass has information necessary for issuance to continuing purchasers recorded on a magnetic track other than the magnetic track for automatic ticket gates, if this information disappears, the commuter pass cannot be reissued. However, there is also the drawback that this information may be tampered with. [Objective of the Invention] This invention was made based on the above circumstances, and it is intended that magnetic It is an object of the present invention to provide a magnetic card that prevents magnetic information recorded on a track from being easily erased.

[Summary of the invention]

In order to achieve the above-mentioned object, the present invention consists of a magnetic track (second magnetic track) other than the magnetic track (first magnetic track) for checking when the card is used, made of a magnetic material with high coercive force. This prevents the recorded information from disappearing and has nine characteristics.
