Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a so-called scratch card in which a concealing layer is removed by rubbing or the like to visually check confidential information, and more particularly to a telephone card for international calls and a prepaid card for personal computer communication. The present invention relates to a scratch card suitable for sale at vending machines and the like.

[0002]

2. Description of the Related Art Conventionally, a so-called scratchable printing layer which can be scraped off by rubbing a fragile silver-colored concealing layer with a coin or the like is formed on a lottery result ("hit", "losing", etc.). The provided cards are known (JP-B-48-28453, JP-B-2-3897, JP-A-1-257100, JP-A-2-297).
482, JP-A-7-108751, etc.).

[0003] Conventionally, this type of scratch card has been
It is mainly used as treasure lottery cards and lottery lottery cards. These lottery cards are exchanged for cash or prizes as soon as the card user confirms the lottery results.
The card is not required to be durable, and is often a paper card because it is manufactured at low cost. In this paper lottery card, thick paper is used to maintain a certain degree of rigidity. For this reason, even when the paper lottery card is carried from the manufacturer to a store or the like, a large number of cards are not bundled, and a small number of cards are bundled with a rubber band. Have been broken. Also, these lottery cards were handed out and were not sold at vending machines.

On the other hand, recently, with the spread of international telephone and personal computer communication, prepaid cards used for them have begun to be used. In a conventional prepaid card such as a telephone card, balance information is read from a magnetic recording layer provided on the card, and new balance information obtained by subtracting the used amount is written in the magnetic recording layer. In this method, unauthorized tampering, forgery, and the like occur frequently because the balance information is easily updated.

For this reason, a prepaid card for an international call or the like employs another system. In other words, only the personal identification number is displayed on the card, and when making an international call, the personal identification number is input and connected to the host computer. Since all the balance information is managed by the host computer, it is unlikely that the balance information is tampered with. Such a prepaid card employs a scratch card that is highly confidential and can be easily viewed in order to conceal the personal identification number.

[0006]

However, the scratch card used for international calls and the like cannot use the scratch card conventionally used for the lottery as it is because of the difference in the usage method and the like. Such a problem has arisen.

That is, unlike the lottery card, the scratch card for international calls is often carried for a long period of time. Therefore, a thin plastic card is mainly used to improve portability and durability. Since such a scratch card is thin, a large number of cards can be bundled, and when the card is carried from a manufacturer to a store or the like, a large number of cards are stacked and carried. However, if a relatively thick scratch layer is provided, the card is inclined due to the thickness of the scratch layer of the bundled cards during such carrying (see FIG. 7). However, because of the smoothness and low frictional resistance, the bundled cards collapsed and the transportability was poor.

[0008] Scratch cards used for international calls and the like are often sold by vending machines, unlike lottery cards handed by hand. At least 300 or more cards are stacked and stored in the stacker in the vending machine, but also in this case, the stacked cards are inclined due to the thickness of the scratch layer (FIG. 7).
(See Reference.) The balance became poor, causing resistance when unloading from the stacker, causing card jams and the like.

It is an object of the present invention to provide a scratch card which does not collapse or cause card jam even when many cards are stacked.

Embodiments of the present invention will be described below in more detail with reference to the drawings. (First Embodiment) FIG. 1 is a plan view showing a scratch card according to a first embodiment of the present invention, and FIG. 2 is a sectional view taken along line BB. The scratch card 10 includes a card base 11 and
A secret information display section 12, a protective layer 13, a concealing layer 14,
And a tilt suppression layer 15.

The card substrate 11 is a substrate serving as a carrier of the card. In a predetermined area of the card base material 11, a pattern 1
1a etc. are printed. As a material of the card base material 11, a commonly used plastic material (for example,
Vinyl chloride, PMMA, PET, ABS, polyolefin, PET-G, polycarbonate, acrylonitrile-styrene copolymer, cellulose propionate, cellulose acetate butyrate, etc.), alloy material, or paper (for example, art paper, coated paper, Synthetic paper) is preferably used. The thickness of the card base material 11 is, for example, P
When ET is used, it is about 125 μm.

The picture 11a can be printed by one or a combination of two or more of offset printing, screen printing, gravure printing, contact / non-contact toner fixing method and the like.

The confidential information display section 12 is a display section formed on the card base 11, and the confidential information 12 to be kept secret.
a is displayed. The secret information display section 12 is formed along a side 11b parallel to the direction in which the scratch card 10 is carried by the carrying device.

The secret information 12a is often variable information that differs for each card, such as a personal identification number that is input when using an international call, but may be fixed information. In the case of variable information, it may be printed by a printer or the like. Also,
In the case of variable information, it may be formed by normal printing or the like. Specifically, printers for variable information include dot impact printers, thermal printers, thermal transfer printers, inkjet printers, electrostatic toner printers, and the like. In addition, as printing in the case of fixed information,
Offset printing, silk printing, live plate printing, etc.

The secret information 12a is character data, an image, a code, a mark, and the like. Furthermore, the secret information 12a
Since confidentiality is required, it is desirable that the surface has few irregularities. In other words, if the surface has irregularities, even if the surface is concealed by the concealment layer 14, there is a possibility that the confidential information 12a can be seen from above the concealment layer 14 by light reflection. Specifically, the unevenness is desirably within 5 μm. Furthermore, the secret information 12a is preferably printed or printed in a color similar to that of the concealing layer 14. A combination of the background (card base material 11), the secret information 12a, and the color of the concealing layer 14 may be used to select a color in which the confidential information 12a is least visible when the concealing layer 14 is formed.

The protective layer 13 is a layer that gives the exfoliation suitability of the concealing layer 14 when the concealing layer 14 is scraped off, and protects the secret information display section 12 so that the secret information 12a does not peel off. The material of the protective layer 13 is preferably polyvinyl chloride, but may be polyethylene terephthalate, polycarbonate, or the like. The thickness of the protective layer 13 is, for example, about 50 μm when using polyvinyl chloride. The protective layer 13 is formed by being attached to the card base material 11. As an adhesive for bonding the protective layer 13, a phenol resin,
Epoxy resin, melamine resin, urea resin, polyurethane, natural rubber, PMMA, and the like are preferably used, and are formed using a method such as a miller coat, a gravure coat, a flow coat, a comma coat, and a roll coat. Protective layer 1
3 has a thickness of 5 to 30 μm.

The concealing layer 14 is a concealing layer formed on the secret information display section 12 along the entire length of the side 11b parallel to the direction in which the scratch card 10 is carried by the carrying device. Further, the concealing layer 14 is formed of a base (secret information 1).
It has the concealing property (opacity) of 2a) and is scraped off by rubbing with a nail or a coin (it can be scratched). Further, it can be peeled off using a cellophane tape, a mending tape, or the like. In the state where the concealing layer 14 is formed, the secret information 12a is invisible from the outside even if the vehicle is illuminated with the headlights of a car.
When the concealing layer 14 is scratched, the secret information 12a becomes visible from outside.

The ink forming the concealing layer 14 is a vehicle (pigment) made of rubber and a thermoplastic resin (natural rubber, synthetic rubber, chlorinated polyethylene, chlorinated polypropylene, chlorinated rubber, ethylene vinyl acetate copolymer resin, ABS resin, etc.). For transferring and fixing to the printing surface). Further, in order to obtain the hiding property of the base, inorganic and organic pigments (iron oxide, titanium oxide, cobalt oxide, pearlescent pigment, phthalocyanine blue, insoluble azo, soluble azo, dye lake, etc.) and / or metal powder (bronze) , Aluminum, etc.), and also contains an appropriate plasticizer, stabilizer, release agent and solvent.

Representative examples of such inks include, for example, Sericol RU manufactured by Teikoku Ink Mfg. Co., Ltd.
B ink and the like.

The concealing layer 14 is printed by silk screen printing. The thickness of the concealing layer 14 is particularly 10 to 20 μm.
m is preferable, but may be about 5 to 30 μm. Thickness 5
When the thickness is less than μm, the base material is transparent and the concealing property is poor.
If the thickness is 30 μm or more, printing suitability and transport suitability are poor.

The inclination suppressing layer 15 is a layer formed on the card substrate 11 and is formed symmetrically with respect to the concealing layer 14 about the center of gravity 11G of the card substrate 11. The inclination suppressing layer 15 has substantially the same thickness as the concealing layer 14. Further, the inclination suppressing layer 15 has substantially the same frictional resistance as the concealing layer 14.

As the ink for forming the inclination suppressing layer 15, the ink for forming the concealing layer 14 which is obtained by removing pigments added for obtaining the concealing property of the base is preferably used.
Alternatively, the same ink as the ink forming the concealing layer 14 may be used. Using such an ink, the inclination suppressing layer 15
Is printed by silk screen printing. Incline suppression layer 1
The thickness of 5 is substantially equal to that of the concealing layer 14.

FIG. 3 is a diagram showing a use state of the first embodiment of the scratch card according to the present invention. According to the present embodiment, the inclination suppressing layer 15 is provided at the center of gravity 1 of the card base material 11.
Since the scratch cards 10 are formed symmetrically with respect to the concealing layer 14 and about the same thickness as the concealing layer 14 around 1G, even if a large number of the scratch cards 10 are stacked, the scratch cards 10 do not collapse and collapse. Can be stacked.

The concealing layer 14 is formed along the entire length of the side 11b parallel to the direction in which the concealing layer 14 is conveyed by the conveying device. Because of the resistance, the scratch card 10 is transported smoothly. That is, the concealing layer 14 is
b is formed along the entire length of the scratch card 10, so that the concealing layer 14 is in contact with the card base material 11 of the scratch card 10 stacked on or below during transportation of the scratch card 10.
Scratch card 1
This is because 0 can be transported with a substantially constant force. Concealment layer 14
Since the frictional resistance is greater than the frictional resistance of the surface of the card substrate 11, if the concealing layer 14 and the card substrate 11
If the card comes in contact with the card base material 11 alternately, the frictional resistance changes with each change, and chatter or the like may occur at the time of carrying the card, and the card may not be smoothly carried. However, in the scratch card 10 of the present embodiment, since the concealing layer 14 is in contact with the card substrate 11 over substantially the entire area,
Such chatter and the like hardly occur, and the paper is smoothly transported.

If the frictional resistance of the inclination suppressing layer 15 is small, the concealing layer 14 has a large frictional resistance, so that the card is rotated in a plan view due to the frictional resistance of the concealing layer 14 during transport of the card. Movement occurs. However, in the present embodiment, the frictional resistance of the inclination suppressing layer 15
, The frictional resistance of the inclination suppressing layer 15 and the frictional resistance of the concealment layer 14 are balanced, and such rotation does not occur, so that the conveyance can be performed smoothly.

Further, the concealing layer 1 of the scratch card 10
Even if it is set in a stacker with the surface on which the layer 4 is formed downward, the concealing layer 14 is not damaged. That is, the transporter of a stacker usually has a structure in which a card is transported by rollers near the center, but the scratch card 10
Has a concealing layer 14 near the edge of the card,
Since the roller does not contact the concealing layer 14, the concealing layer 14
Does not damage.

(Second Embodiment) FIG. 4 is a plan view showing a scratch card according to a second embodiment of the present invention. Note that the same reference numerals are given to portions that perform the same functions as in the above-described first embodiment, and overlapping descriptions will be omitted as appropriate. The concealing layer 14 is formed in a rectangular shape in parallel with the direction in which the concealing layer 14 is carried by the carrying device. In addition, the inclination suppressing layer 15
Are formed symmetrically on the concealing layer 14 around the center of gravity 11G of the card base material 11.

As in the present embodiment, the inclination suppressing layer 15
If the shape and position are determined according to the concealing layer 14, the same effects as in the first embodiment can be obtained.

(Third Embodiment) FIG. 5 is a plan view showing a scratch card according to a third embodiment of the present invention. The concealing layer 14 is formed in a rectangular shape in parallel with the direction in which the concealing layer 14 is carried by the carrying device. Moreover, if the inclination suppressing layer 15 is formed so as to surround the center of gravity 11G of the card base material 11 together with the concealing layer 14, the inclination suppressing layer 15 may be formed in a dot shape.

According to the present embodiment, even when a large number of scratch cards 10 are stacked, the scratch cards 10 do not tilt and collapse.

(Modifications) Various modifications and changes are possible without being limited to the above-described embodiment, and these are also within the equivalent scope of the present invention. For example, the protective layer 1
3 is deleted when the secret information display section 12 has sufficient adhesion to the card base material 11 and the concealing layer 14 has sufficient peelability to the card base material 11. (FIG. 6). When the above-mentioned suitability cannot be obtained with a single layer, the protective layer 13 may be formed by lamination. Further, the protective layer 13 may be formed by printing an OP ink. As a printing method, offset printing, silk screen printing, gravure printing, or the like is used. At this time, it is preferable to use a radiation-curable resin such as a UV-curable resin or an EB-curable resin as a binder for the OP ink. This is because a dense film can be formed, so that the protection of the secret information display section 12 and the releasability of the concealing layer 14 can be satisfied.

The inclination suppressing layer 15 may be formed on the entire surface of the card substrate 11 so as to surround the concealing layer 14.
In addition, the inclination suppressing layer 15 may transfer a foil having substantially the same thickness as the concealing layer 14 by hot stamping. Further, the inclination suppressing layer 1
5 may be formed as a design such as a character or a mark.

[0039]

As described in detail above, according to the first aspect of the present invention, since the inclination suppressing layer is provided, the scratch cards can be stacked.

According to the second aspect of the present invention, the inclination suppressing layer comprises:
Since it is formed on the opposite side of the concealing layer with respect to the center of gravity of the card base material, it is possible to stack many scratch cards.

According to the third aspect of the present invention, the concealing layer is formed parallel to the direction in which the card is conveyed by the conveying device, so that the card can be smoothly conveyed.

According to the fourth aspect of the present invention, the inclination suppressing layer comprises:
Since the concealing layer is formed symmetrically with respect to the center of gravity of the card base, the card can be stably conveyed.

According to the fifth aspect of the present invention, the inclination suppressing layer comprises:
Since the card has substantially the same frictional resistance as the concealing layer, the card can be transported more stably.

According to the sixth aspect of the present invention, the inclination suppressing layer comprises:
Since the concealing layer is formed of the same material as the concealing layer, the inclination suppressing layer can be formed simultaneously with the concealing layer.
