Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an information card that can electrically process data at low cost.

BACKGROUND OF THE INVENTION In recent years, there has been remarkable progress in electrical processing technology for information and data and its substantial practical application.

However, if we focus on individual information or data, we can see that some parts are still being left out. One of them is business card information.

Conventionally, business card holders with many storage pockets have been mainly used to organize business card information. However, searching through business cards to get the information you need can take quite a while, depending on how you organize them. A common method to reduce search time is to store each business card information in a data file that can be controlled by a computer, but storing the information generally requires keystrokes as in the case of using a word processor. However, there was still the problem that it took time and effort. In order to solve such problems, the business card information is encoded and drawn on the card using printing technology such as screen printing or a printer controlled by electrical signals, etc. There is a method of reading with an image sensor or the like.

Problems to be Solved by the Invention However, with the above configuration, when trying to draw encoded character information etc. on a card, it is difficult to draw coded information such as character information on a card using a printing machine such as a screen printer or a controller such as a personal computer. It required fairly costly equipment such as a controlled printer, and had the problem of being disadvantageous in terms of cost when trying to produce large quantities of identical items such as business cards. .

In view of the above-mentioned problems, the present invention provides an inexpensive information card that can be manufactured using a simple manufacturing method and that allows information data to be read 9 easily.

Means for Solving the Problems In order to solve the above problems, the information card of the present invention includes a plurality of characters, coded character information corresponding to each character, and coded character information attached to each character information. Identification codes are arranged on the same surface or both sides, and the plurality of coded character information and the corresponding identification codes are constructed using a pressure-sensitive coloring material.

Effects of the Invention With the above-described configuration, the present invention allows character information encoded on a card to be created in a simple manner, and the information data to be read easily.

Embodiment Hereinafter, an information card according to an embodiment of the present invention will be described with reference to the drawings. "FIG. 1 shows a plan view of an information card according to an embodiment of the present invention.

In FIG. 1, 1Fi.

This is the information card itself. 2 is a string of characters indicating kanji, kana, alphanumeric characters, simple symbols, etc., and 3 is a 2-byte code, timing code, and error check code for each character in the string. The code block shown is shown below.

The reason why the code blocks 3 are arranged around the information card 1 as shown in FIG. 1 is to make it easier to read when using a reading device such as an image sensor that takes several seconds to read.

FIG. 2 is a code pattern diagram showing a detailed example of a part of the code block 3 in FIG. The 1st and 2nd lines indicated by 6.7 show the timing code, and the 16 lines from the 3rd and 4th line to the 18th line shown by 6.7 show the 2-byte character code corresponding to each character. Line 19 shows an error check code for even or odd parity check,
Each column corresponds to each character.

In Figure 2, the length of the code corresponding to each character is ft2
The reason for using byte is that the reading address of kanji ROMs with about 3000 characters used in recent zero-person devices, personal computers, etc. is often specified in 2 bytes, so it is better to match with these devices. This is because we took this into consideration.

FIG. 3 shows a cross-sectional view of the person-to-person part shown in the code pattern diagram of FIG. 2, where 8 is a color developer layer and 9
10 is a microcapsule containing a color former solution, and 10 is a card base material. Reference numeral 11 denotes a pressure section that applies pressure to the card to cause it to develop color when producing coded character information or the like on the card.

In FIG. 3, when pressure is applied to the card by the pressure applying unit 11, the card is in a colorless state before the pressure is applied;
The microcapsules 9 in the convex portion of the pressurizing part 11 are destroyed and the coloring agent solution is released.

Then, in contact with the color developer of the color developer layer 8 in the same layer, only the portion facing the convex portion of the pressure member 11 develops color. In other words, it is sufficient to prepare the pressurizing section 11 corresponding to the character code, use it to apply pressure to the card, color it in a predetermined code pattern, and read this with a reader such as an image sensor. Become.

As the above-mentioned color-forming materials, combinations of materials that change color from colorless to colored when they react are known, such as a color-forming reaction between a dithiooxamide compound and nickel, or a chelate color-forming reaction between iron or vanadium compounds and tannic acid or gallic acid. ing. If any one of these color-forming materials is contained in the microcapsules 9 and combined, a pressure-sensitive color-forming material can be obtained. Furthermore, a pressure-sensitive coloring material made from a colorless dye precursor (leuco dye) can also be used. On the other hand, the color developer used in combination with this coloring material includes specially treated acid clay, an initial polymer of phenol-formalin resin, an aromatic carboxylic acid derivative, and the like.

The microcapsules 9 are made of natural polymers such as gelatin and gum arabic, synthetic polymers such as polyamide and polyurethane, or thermosetting resins such as urea-formalin resin. In addition, the solvent for the coloring agent contained in the microcapsules must be one that dissolves the coloring agent well, is nonvolatile and stable, and has almost no solubility in water for encapsulation. Synthetic oils such as biphenyl, diphenylalkane, and dibutyl phthalate are used.

As described above, according to this embodiment, character information encoded on the card can be obtained by a simple method such as applying pressure, and an information card whose information code can be easily read can be obtained.

In addition, in the above embodiment, an application in which a plurality of character strings and information codes are mixed together, such as a business card, was explained, but the information code is provided on the entire surface of the information card, and for example, a program for a personal computer can be coded. It is also possible to obtain an inexpensive program card by

Further, in the above embodiment, the length of one code is 2 bytes, but the length is not particularly limited to 2 bytes, and may be, for example, 1 byte.

Effects of the Invention As described above, the present invention provides a method in which a plurality of characters, coded character information corresponding to each character, and an identification code attached to each character information are arranged on the same side or on both sides,
The above-mentioned pieces of encoded character information and their corresponding identification codes are constructed using a pressure-sensitive coloring material, so the character information encoded on the card can be easily read by applying pressure. This provides an excellent effect of providing an information card whose information code can be easily read.
