Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a method for displaying information on a recording medium, and more specifically, the present invention relates to a method for displaying information on a recording medium, and more specifically, information in an information recording section is displayed in response to the use of a prepaid card or a stamp service card. The present invention relates to a method for clearly displaying a measure of change in information on a recording medium that changes.

(Prior Art) Conventionally, a prepaid card such as a cash card, telephone card, ticket purchase card, etc., on which specific information is recorded in advance, is purchased, and each time the card is used at a vending machine, etc., the information is recorded. Recording media such as cards on which stored information changes have become widely used.

These prepaid cards display changes in information, such as increases and decreases in value information, as necessary during use so that the user can see changes in the information recorded therein.

Examples of the above methods for displaying changes in information include: (+) a punching method in which changes in information on a recording medium are displayed by punching holes in the recording medium; (2) a punching method in which changes in information on a recording medium are Marking methods such as maniking and displaying on media have been used.

(Problem to be solved by the invention) Among the above information display methods, the punching method generates a large amount of punch waste, which must be removed periodically.
There are maintenance issues. In addition, since the punch chips are small, there are problems such as the punch chips clogging the discharge port and causing damage to the card reader/writer.
There are many maintenance problems such as the need to replace the punch blade.

In addition, in the case of the display method using the above-mentioned marking method,
There is a method in which a thermosensitive coloring layer is formed in advance on the recording medium itself, such as a card, and marking is done by coloring it with a thermosensitive head.This method does not cause as many maintenance problems as the above-mentioned punching method, but Since there is no dye with excellent weather resistance as a heat-sensitive coloring dye, there is a problem that recording media cannot be stored for a long time, and a mark that is once colored easily fades and loses its display function.

Another method is to use a thermal transfer ribbon to transfer and print the mark on the recording medium.This display method does not have problems with weather resistance, but there are maintenance issues such as replenishing and replacing the transfer ribbon. Furthermore, since the transfer ribbon uses a very thin film, there is a problem in that the ribbon jams inside the device, which can cause malfunctions.

Therefore, there is a need for a simple display method that does not cause maintenance problems or interlayers such as weather resistance of marks, and can easily indicate changes in information on a recording medium.

(Means for Solving the Problems) The present inventor completed the present invention as a result of intensive research in order to meet the demands of the prior art as described above.

That is, the present invention provides a recording medium in which information recorded in an information recording section changes depending on use, and the change in the information is displayed by forming a concave portion and/or a convex portion in a part of the recording medium. A method for displaying information on a recording medium is characterized in that:

(Function) Changes in the information in the recording medium can be detected by creating a recess and/or a part of the recording medium.
Or by displaying by forming a convex part,
Changes in information can be easily manifested visually and tactilely without the punch debris problems, weatherability problems, and maintenance problems of the prior art.

(Preferred Embodiments) The present invention will now be described in more detail with reference to the accompanying drawings, which schematically illustrate preferred embodiments of the present invention.

FIG. 1 shows the surface of a prepaid card 1, which is an example of a recording medium used in the method of the present invention, and FIG.
'This shows a part of the cross section.

The card 1 of this embodiment has a magnetic stripe as an information recording section 2 on a card base made of polyester or polyvinyl chloride resin and having a thickness of about 0.2 to 0.8 mm. Such a magnetic card, for example,
When used as a private card, arbitrary printing is applied to the surface of the card 1, and, for example, a scale and a number 3 are printed to indicate the approximate remaining amount of the card.

The information recording section may be formed on the entire surface of the card using a normal magnetic recording material, but in this example, a 17500e magnetic stripe is used. Necessary information, for example, information equivalent to 10,000 yen, is recorded in this information recording section,
Each time it is used, the amount is subtracted according to the amount used, and new information is recorded in the information recording section. For example, with this card you can get 2,000
If you make a purchase worth 0 yen, the remaining amount will be 8,000 yen, so the information in the information recording section of the card will be rewritten to 8,000 yen, and this fact will be displayed at scale 8 on the card. This operation is repeated each time the card is used, and a mark is similarly placed at the position corresponding to the remaining amount.

The main feature of the method of the present invention is that when using a recording medium such as the one described above, changes in the information recorded in the information recording section can be changed as shown in FIGS.
As shown in the figure, there are concave and/or convex portions 4 at predetermined positions on the recording medium.
It is used to display changes in information by forming .

The method of forming the recesses and/or protrusions 4 at predetermined positions on the recording medium 1 may be any method and is not particularly limited, but in this embodiment, as shown in FIG. The molds 5 and 6 were arranged and connected to a card reader/writer, and the molds 5 and 6 were electrically operated and crimped. At this time, since the cart 1 is often made of a relatively soft thermoplastic resin, the desired recesses and/or protrusions 4 can be easily formed without applying any heat, but of course the mold must be heated. You can leave it as is. The size and height and depth of the recesses and/or protrusions to be formed may be any size and depth that can be easily determined with the naked eye or touch, for example, 0.01 to 3 m1 with a size of about 0.5 to 3 m1. The height and depth are approximately 1 mm.

4 and 5 show another preferred embodiment of the present invention, in which the portion of the card where the convex portion is to be formed is placed on the card base material 7 with a material having good elasticity, for example, on the card surface. Vinyl chloride-vinyl acetate copolymer layer 8 colored in a different color from
A layer 9 of another hue (e.g. white) is formed thereon from a relatively brittle resin, e.g. UV curable ink or paint, to hide the color of the underlying layer 8. This is an example. When a convex part is formed as described above in such a layer structure, as shown in Fig. 5, the top layer is destroyed because it is a brittle layer, while the layer below it is destroyed because it is a soft layer. This is preferable because the convex portions can be exposed on the surface without being exposed, and the convex portions can be more easily distinguished due to the color contrast with the surface layer.

Although the present invention has been described above using preferred embodiments of the present invention, the present invention is of course not limited to these embodiments, and includes various embodiments. For example, the recording medium may be limited to the form of a card. Moreover, the information recording portion does not have to be in the form of a stripe, and may be a magnetic layer over the entire surface. Further, it is natural that the information recording section is not limited to the value information described above, and can record any information such as a company code, date of issue, amount of money at the time of issue, security code, etc. Therefore, the portion where the recesses and/or projections are to be formed may also be a magnetic layer. Further, the uneven portions to be formed do not have to be convex portions, but may be concave portions, or concave portions and convex portions may be formed alternately, and the shape of the concave portions and/or convex portions may be circular or hemispherical. It is not limited to this, and may be in the shape of a triangle, square, numbers, or letters. Furthermore, even when the above-mentioned convex portions are displayed in a different color, it is not necessary to provide the intermediate colored layer 8 as long as the card base material 7 itself is colored. Furthermore, instead of providing a colored layer as described above, a coloring layer that develops color by heat or pressure can be provided at the place where the unevenness is to be formed, and the coloring can be caused by the heat or pressure when forming the unevenness.

(Effects) According to the present invention as described above, the following effects are achieved compared to the prior art.

(1) Compared to the punching method, there is no punch waste, and there is no need for maintenance or machine failure due to punch waste.
Various problems such as punch blade wear were solved at the same time.

(2) Compared to marking methods, problems such as mark resistance and loss due to wear do not occur, and a permanent mark can be formed.

(3) In a more preferred embodiment, the concave and/or convex portions can be made to have a different hue from the other portions without using any marking agent or device, making visual identification easier.

(4) Even visually impaired people can now easily distinguish by touch.
