However, since prepaid cards are usually made of materials such as plastic and polyester,
In order to incinerate this, it is necessary to raise the temperature in the incinerator to a temperature that is considerably higher than that of ordinary garbage, and as a result, the prepaid card will not be burned together with the garbage that burns over a long period of time. When incinerated in an incinerator, finally,
There are problems such as damage to the incinerator, and generation of harmful substances when burned with burning dust, which leads to environmental damage such as air pollution. In addition, recently, prepaid cards such as used telephone cards have been modified,
It is also a big social problem that it is forged and used illegally.

Therefore, it is urgently necessary to collect and reuse the prepaid card currently in use after it is used, instead of simply discarding it as garbage, to reduce environmental damage and adverse effects on society.

For that purpose, it is necessary to destroy only the magnetic surface of the prepaid card to prevent forgery or alteration, and to collect the card as it is without damaging the card body, especially the decorative surface of the card. Conventionally, as a device for destroying the magnetic surface of this kind of prepaid card, the magnetic surface of the telephone card is destroyed by cutting the magnetic surface of the telephone card linearly in the lateral direction with a cutting blade. Things are known.

[0006]

However, in the conventional device for cutting and destroying the above-mentioned telephone card, the cutting blade wears quickly and the number of used telephone cards that can be cut with one cutting blade is large. The number of cutting blades is small, and the cutting blades must be replaced frequently, so the work efficiency is not good, the cost of the cutting blades is high, and the device is complicated, large, and expensive. However, there is a problem in that the range of use of is limited only to telephone cards, and other prepaid cards cannot be processed.

The present invention has been made in order to solve the above problems, and it does not damage visible information such as advertisements and pictures drawn on the surface thereof, and only a large amount of information is recorded on the magnetic surface of the prepaid card. And it's easy and cheap to destroy, to prevent forgery and alteration of used prepaid cards,
It is an object of the present invention to provide a prepaid card magnetic surface destruction device that can be reused without damaging the commercial value.

[0008]

In order to achieve the above object, the present invention comprises a substrate on which a back surface of a prepaid card on which a magnetic surface is formed is slid, and a conveying means for transferring the prepaid card along the substrate. A pressing unit that presses the magnetic surface of the prepaid card transferred by the transfer unit against the substrate; a position restricting unit that restricts the lateral position of the prepaid card transferred by the transfer unit; and a predetermined position from the surface of the substrate. Destruction means for destroying the information recording portion on the magnetic surface transferred by the conveying means by protruding by the size.

In the second aspect of the invention, it is desirable that the breaking means is a metal brush, a grindstone, or sandpaper.

In the invention according to claim 3, the destruction means may be provided on at least the outer peripheral portion of the rotary plate having a predetermined width which rotates in the direction orthogonal to the transfer direction of the prepaid card.

In the invention of claim 4, the destruction means may be provided on at least the outer peripheral portion of the rotary plate having a predetermined width which rotates in the same direction as the transfer direction of the prepaid card.

The invention according to claim 5 is characterized in that the destruction means are provided on both sides of the information recording portion of the magnetic surface of the prepaid card and a position facing the information recording portion.

The invention according to claim 6 is characterized in that the projecting dimension of the destruction means from the surface of the substrate is larger than the thickness dimension of the magnetic layer of the prepaid card.

In the invention according to claim 7, the breaking means may include a protrusion position adjusting mechanism for adjusting a protrusion dimension from the surface of the substrate.

The invention according to claim 8 is characterized in that the carrying means is a carrying belt made of rubber which comes into close contact with the surface of the prepaid card.

According to a ninth aspect of the present invention, the pressing means comprises a rotating roller for rotatably pressing the surface of the prepaid card, and the rotating roller has a back surface at a point where the breaking means contacts the magnetic surface of the prepaid card. It is characterized by being placed in.

[0017]

According to the prepaid card magnetic surface destruction apparatus of the present invention, the prepaid card is transported on the surface of the substrate by the conveying means. When the prepaid card reaches the position of the destruction means, the information of the magnetic surface is destroyed by the destruction means. The recording portion is destroyed to a predetermined depth, and the information recorded on the magnetic surface is destroyed. When the magnetic surface is destroyed by the destruction means, since the prepaid card is pressed against the surface of the substrate, the prepaid card does not float up from the surface of the substrate during the destruction and is laterally displaced by the position regulation means. Without doing so, the magnetic surface is continuously destroyed to a predetermined depth, and a fracture groove is formed in the information recording portion of the magnetic surface.

Since at least the outer peripheral portion of the rotating plate is constituted by the metal brush, the grindstone, and the sandpaper as the destructive means, the magnetic surface of the prepaid card is efficiently ground and destroyed, and the destructive means is not affected by abrasion. It will not be received and the life of the destruction means will be extended.

When the destruction means rotates in a direction orthogonal to the direction of transfer of the prepaid card, a longitudinal destruction groove is formed on the magnetic surface, which is destroyed in the lateral direction of the prepaid card. Further, when the breaking means rotates in the transfer direction of the prepaid card, the magnetic surface is formed with a broken groove which is broken in the longitudinal direction of the prepaid card.

Further, since the destruction means is provided in two places, that is, the information recording portion on the magnetic surface of the prepaid card and the position where the information recording portion faces each other, even if the prepaid card is transferred left and right, The information recording portion on the magnetic surface is always destroyed by either of the destroying means. Further, since the projecting dimension of the destruction means from the substrate surface is set deeper than the magnetic layer of the prepaid card, the information formed on the magnetic surface is completely destroyed. Further, the projecting position adjusting mechanism of the breaking means adjusts the projecting dimension of the breaking means according to the wear state of the breaking means, whereby the breaking depth of the breaking groove formed on the magnetic surface is maintained constant.

Since the conveying means is a rubber conveying belt that adheres closely to the surface of the prepaid card, a large abrasion resistance is generated between the magnetic surface of the prepaid card and the surface opposite to the magnetic surface, that is, the surface, which causes the prepaid card. The surface of the prepaid card is securely caught, and the prepaid card slides smoothly along the surface of the substrate.

Since the pressing means is composed of a rotating roller, and the rotating roller presses the back surface of the magnetic surface to be destroyed by the destroying means, the destroying means prevents the prepaid card from floating above the surface of the substrate, and the prepaid card. Destruction grooves having a certain depth are formed on the magnetic surface of the magnetic recording medium to completely destroy the information recorded on the magnetic surface.

In this embodiment, the destruction means 7 has a width of 4 to 5 which rotates in the direction orthogonal to the transfer direction of the prepaid card 2.
A metal brush is provided on the outer peripheral portion 7b of the rotating plate 7a of mm, and is driven to rotate by a driving means (not shown) such as a motor. This destruction means 7 is located at the position where the information recording portion of the magnetic surface 2a of the prepaid card 2 is provided (FIG. 1).
2) and the relative position (dimension b in FIG. 1) of the information recording portion on the magnetic surface are provided side by side. The position dimension a of the destroying means depends on where on the magnetic surface 2a of the prepaid card 2 the information recording section is provided.
It only has to be decided, and the size b is the prepaid card 2
It may be provided at a position symmetrical to the position at which the information recording unit is provided with the center line in the lateral direction of as the axis. In this way, by providing the destruction means 7 on both sides of the prepaid card 2, the information recording section is always destroyed even when the prepaid card is inserted from the insertion slot to the left and right.

Further, the metal brush 7 as the destruction means is
The prepaid card 2 is made of a material that is sufficiently harder than the magnetic layer 2c of the prepaid card 2 and the material of which the material is made of plastic or polyester. As shown in FIG. 4, the protruding dimension is slightly larger than the thickness dimension c of the magnetic layer 2c formed on the back surface of the prepaid card 2. The protrusion size of the metal brush 7 can be adjusted as appropriate by providing a protrusion position adjusting mechanism that brings the rotary plate 7a closer to or farther from the substrate 3, and the metal brush that constitutes the destruction means. The grinding depth of 7 can be kept constant or adjusted. Thereby, along the longitudinal direction of the prepaid card 2, the destruction grooves 10 ground to the desired width and depth are formed at two positions, that is, the information recording portion of the magnetic surface 2a and the position opposite thereto.

The transfer means 4 is composed of a rubber transfer belt, and the transfer belt 4 is rotationally driven along the longitudinal direction of the substrate 2 by being rotationally driven by a driving means (not shown). The surface of the conveyor belt 4 is brought into close contact with the surface 2a of the prepaid card 2 to generate abrasion resistance between the prepaid card 2 and the prepaid card 2.
I try to slide along a. It should be noted that the moving speed of the conveyor belt 4 may be determined by appropriately selecting the optimum speed for grinding and breaking the magnetic surface.

The pressing means 5 is composed of a rotary roller 5b rotatably supported by a rotary shaft 5a, and at least the surface of the rotary roller 5b is made of a material such as hard rubber or resin. Then, by positioning the rotary roller 5b on the central axis of the rotary plate 7a of the breaking means 7, the breaking point of the prepaid card 2 due to grinding is rotatably pressed from its surface 2d via the prepaid card 2. As a result, even if the prepaid card 2 is transferred onto the substrate 3 while being ground and destroyed, the magnetic surface 2a does not rise above the surface 3a of the substrate 3. The pressing roller 5 is also provided with the rotating roller 5b on the substrate 2.
It is also possible to provide a position adjusting mechanism that separates and contacts in the direction of.

As described above, according to the prepaid card magnetic surface destruction apparatus 1 of this embodiment, the prepaid card 2 is used.
When the prepaid card 2 is inserted through the insertion port, the prepaid card 2 is transported while sliding on the surface 3a of the substrate 3 by the rubber conveyor belt 4. The prepaid card 2 that slides on the surface of the substrate 3 reaches the position of the destruction means 7 without being displaced in the lateral direction because the lateral position of the prepaid card 2 is regulated by the guide member 6. Then, at this position, the metal brush 7 rotating in the direction orthogonal to the moving direction of the prepaid card 2.
As a result, the information recording portion of the magnetic surface 2a is ground and destroyed.

In this case, the metal brush 7 constituting the breaking means rotates in a direction orthogonal to the traveling direction of the prepaid card 2 as shown in FIG. Although a force acts in the lateral direction, since this force is supported by the guide member 6, it has little influence on the moving direction of the prepaid card 2, and the prepaid card 2 smoothly transfers the surface 3a of the substrate 3 and grinds it. Is destroyed. Further, since the metal brush 7 projects from the surface 3a of the substrate 3 by the dimension c, the magnetic layer 2c is completely scraped off and reaches the cloth 2b of the prepaid card 2. Therefore, a material such as plastic is exposed in white on the back surface of the prepaid card 2 which is ground and destroyed. Therefore, the information recording section is also completely destroyed.

When the magnetic layer 2c is ground and broken by the metal brush 7, the prepaid card 2 is movably pressed by the rotary roller 5b from the back surface of the breaking point, that is, the front surface 2d side of the prepaid card 2. Since the prepaid card 2 does not float up from the front surface 3a of the substrate 3 even during grinding and destruction, the back surface of the prepaid card 2 is continuously ground to a certain depth and destroyed. Two parallel fracture grooves 10 are formed on the back surface of 2.

Furthermore, the metal brush 7 as a destruction means
Has a sufficient hardness, so it has high wear resistance,
Even if it wears to some extent, it does not become sharp like a conventional cutting blade, the grinding destruction efficiency does not decrease, and the life of the destruction means can be maintained for a long time. The magnetic surface 2a of the card 2 can be efficiently ground and destroyed. Also, destruction means 7
Since the prepaid card 2 is provided at two places, the information recording part and the relative position thereof, even if the prepaid card 2 is inserted from the insertion slot to the left and right and transferred, by any of the destruction means 7, The information recording part is always destroyed.

Since the conveying means 4 is constituted by a rubber conveying belt and the rotating roller 5b of the pressing means 5 is constituted by a material such as hard rubber or resin, it is applied to the surface of the prepaid card 2. Without damaging the visible information
The prepaid card 2 can be reliably run along the surface 3a of the substrate 3.
