Abstract

PURPOSE: To easily find out tampering with printing contents and prevent forgery of a card by previously recording characters and numeral characters corresponding to a part of the printing contents in a setting area as a non-printing part on a heat reversible thermal recording layer in a printing area as concealed characters and numerals. CONSTITUTION: To a white printing part 61 of a printing area 60, concealed characters and numerals 70 which coincide with a part of a printing contents 51 in a setting area 50 are added. Also in the white printing part 61, on a heat reversible thermal recording layer 40 arranged at the lower part of the printing part 61, an opaque part 41 which coincides with a part of the printing contents 51 is formed. With only a glance at the white printing part 61, the presence of the concealed characters and numerals 70 can not be recognized. However, when they are scrutinized, by the contrast between the opaque part 41 and a transparent part 42 on the heat reversible thermal recording layer 40, the presence of the concealed characters and numerals 70 can be recognized on the surface of the white printing part 61, so that the printing contents do not coincide if the printing contents 51 in the setting area 50 is tampered, thereby finding out forgery immediately.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rewritable thermosensitive recording type card using a thermoreversible thermosensitive recording material, and more particularly to a thermosensitive recording type card capable of preventing tampering of print contents.

[0002]

2. Description of the Related Art For example, as a card used for a cash card, a credit card, a magnetic ticket, etc., the applicant of the present invention has previously described in Japanese Patent Application No. 63-61829 that it can be rewritten using a thermoreversible material. We have proposed a thermal recording card.

This one uses a thermoreversible material effective as a material for the information display portion of a card. This thermoreversible material uses an organic low molecular weight substance and a resin, and is transparent and opaque when heated. It has the characteristic of reversibly changing the state and maintaining the two forms even at room temperature.

Recently, this type of heat-sensitive recording type card has been widely used as a point card and a gift exchange ticket at a playground.

FIGS. 6 and 7 show a front view and a sectional view of a conventional point card. In the drawings, the point card 1 is a vacuum-deposited aluminum deposition layer 3 on the surface of a card base 2 made of polyester resin or the like. , A thermoreversible thermosensitive recording layer 4 is laminated on the surface thereof.

The surface of the thermoreversible thermosensitive recording layer 4 is divided into a printing area 5 and a printing area 6,
In the printing area 6, white printing 6a and color printing 6b are printed.

As the printing method for the point card 1, a thermal printer is used for the thermoreversible thermosensitive recording layer 4 in the transparent state in order to display the printing contents 5a such as date and score in the printing area 5. Form a transparent portion and a cloudy portion.

That is, as shown in FIG. 8, a cloudy portion 4a is formed on the thermoreversible thermosensitive recording layer 4 by a thermal printer.
In the transparent portion 4b, the silver color of the aluminum vapor-deposition layer 3 becomes the background color of the printing area 5, and the portion corresponding to the cloudy portion 4a is a blank portion as the printing content 5a such as date and score. Emerges like this,
By operating the thermal printer, desired print contents 5a are printed and erased, and used as the rewritable point card 1.

[0009]

However, in the conventional point card 1, the point card 1
Although it is possible to easily erase and record the print contents in, the point display on the point card 1 or the ball display on the gift exchange ticket can be easily tampered with, and the reliability of the card is lowered. Was pointed out.

The present invention has been made in view of the above circumstances, and it is possible to easily find out the tampering of the printed contents in a thermosensitive recording type card using a thermoreversible thermosensitive material such as a point card or a gift exchange ticket. It is an object of the present invention to provide a thermal recording type card that can improve the reliability of the card by preventing the card from being forged.

[0011]

In order to achieve the above object, the present invention has a thermoreversible thermosensitive recording layer laminated on the surface of a card base, and a non-printed portion on the thermoreversible thermosensitive recording layer surface. In a thermosensitive recording type card in which a printing area and a printing area are set, a character and a number corresponding to a part of the printing contents of the printing area are recorded as a hidden character and a number in the thermoreversible thermosensitive recording layer in the printing area. It is characterized by

[0012]

As apparent from the above construction, in the heat-sensitive recording type card according to the present invention, the characters and numbers corresponding to a part of the printing contents in the printing area are hidden characters and numbers, and the thermoreversible printing in the printing area is performed. Since it is recorded on the thermosensitive recording layer, if the print contents in the print area are tampered with,
Since the falsified content and the hidden characters and numbers recorded on the printed portion do not match, the forgery of the card can be found immediately.

Furthermore, since the hidden characters and numbers are recorded in the thermoreversible thermosensitive recording layer in the printed portion, the printed contents such as hidden characters and numbers are covered by the printing layer, and at first glance, the existence of them can be confirmed. I can't confirm.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a thermal recording type card according to the present invention will be described below by exemplifying a point card.

FIG. 1 is a plan view of a point card, and FIGS. 2 to 4 are sectional views of the point card. The point card 10 is a card base 2 made of polyester resin or the like.
The aluminum vapor deposition layer 30 is formed on the entire surface of No. 0 by the vacuum vapor deposition method, the sputtering method, the ion plating method, and the thermoreversible thermosensitive recording layer 40 is further formed on the surface thereof.
Are laminated.

Then, a part of the surface of the thermoreversible thermosensitive recording layer 40 is printed so as to be divided into a printing area 50 (non-printing portion) and a printing area 60 (printing portion), and a book. In the embodiment, as the printing area 60, the white printing portion 61 set on the outer periphery of the printing area 52 and the color printing portion 62 overcoated on the surface of the white printing portion 61.
Is set.

Further, in order to display a predetermined print content 51 in the print area 50 of the point card 10, as shown in FIG.
As shown in FIG. 5, in the thermoreversible thermosensitive recording layer 40 corresponding to the print area 50, a cloudy portion 41 that matches the print content 51 such as letters and numbers is formed by a thermal printer or the like not shown. Due to the contrast with the transparent portion 42, the white print content 51 is displayed on the silver background portion which is the surface color of the aluminum vapor deposition layer 30.

By the way, the point card 10 according to the present invention can immediately detect falsification of the print content 51 in the print area 50, and is very effective in preventing forgery of the point card 10.

That is, a characteristic is that a hidden character, numeral 70, which matches a part of the print content 51 in the print area 50, is added to the white print portion 61 of the print area 60 other than the print area 50.

As shown in FIG. 4, even in the white printing portion 61 of the printing area 60, the thermoreversible thermosensitive recording layer 40 located below the white printing portion 61 has the printing content 5 in the printing area 50.
A white turbid portion 41 corresponding to a part of 1 is formed.

Therefore, the presence of the hidden characters and the numbers 70 cannot be confirmed only by looking at the white printing portion 61 in the printing area 60. However, upon careful observation, the white turbid portion 41 and the transparent portion in the thermoreversible thermosensitive recording layer 40 are transparent. Due to the contrast with the portion 42, it is possible to confirm the presence of the hidden character and the numeral 70 on the surface of the white printing portion 61, and by any chance, the printing content 51 of the printing area 50 of the point card 10 is printed.
When tampered with, the printed content 51 does not match the hidden character and the numeral 70, so that the forgery of the point card 10 can be immediately found.

Further, in this embodiment, by adding a hidden character or numeral 70 to the white printing portion 61 adjacent to the printing area 50, the printed content 51 of the printing area 50 is compared with the hidden character or numeral 70. Easy and white printing part 6
Since the print content of hue white is 1, the hidden character, number 70
Although it is not obvious at first glance, it is designed so that you can see it immediately with your eyes.
There is an advantage that the contrast work with the numeral 70 can be easily performed.

FIG. 5 shows another embodiment of the heat-sensitive recording type card according to the present invention. In this embodiment, the printing area 60 is composed of only the color printing section 62, and the color printing section 62 has hidden characters, The number 70 is added.

In the case of this embodiment, the hidden characters and numerals 70 may be set at arbitrary positions of the color printing section 62, but it is preferable to set them at the light-colored printing section for contrasting work.

In this embodiment, it is almost difficult for a third party to identify the existence of the hidden character / numeral 70, so that the function of the hidden character / numeral 70 can be effectively utilized.

Although the above-mentioned embodiment is applied to the point card 10, the heat-sensitive recording type card according to the present invention can be widely used such as a gift exchange ticket in a playground.

Further, in addition to preventing the counterfeiting of the card, a hidden number such as the management number of the issuing side can be printed so that the history of the card can be confirmed, thereby effectively managing the card. It is valid.

[0028]

As described above, the heat-sensitive recording type card according to the present invention is provided with the printing area which is the non-printing portion and the printing area, and the printing contents of the printing area in the white printing portion or the color printing portion Since hidden characters and numbers that match a part are added, when the display in the print area is tampered with, the contents of the print area can be compared with the hidden characters and numbers to immediately tamper with the print contents. It can be found and has a great effect on preventing counterfeiting of cards.

Further, when a hidden character and a hidden number added as a number to the printed portion of the card and the number of times of passing are set, there is an effect that the card can be efficiently managed.
