Description

本発明は、暗証番号を簡単に創作するのに好適な暗証番号創作具に関する。 The present invention relates to a code number creating tool suitable for easily generating a code number.

ＡＴＭ用キャッシュカ−ドに代表される各種金融カ−ドやクレジットカ−ドなどの利用に際しては、通常、個人を認証するために、暗証番号（パスワ−ド）が必要となる。
しかし、カ−ドが複数枚となると、各カ−ドに対応する暗証番号の記憶および管理が困難となる。だからといって各カ−ドに共通の暗証番号を使用したり、電話番号や生年月日を暗証番号としたりすると、第三者に容易に悪用されるおそれがある。 When using various financial cards and credit cards represented by ATM cash cards, a personal identification number (password) is usually required to authenticate an individual.
However, when there are a plurality of cards, it becomes difficult to store and manage the personal identification number corresponding to each card. However, if a common password is used for each card, or if a phone number or date of birth is used as a password, there is a possibility that it can be easily misused by a third party.

そこで、暗証番号やパスワ−ドとして、特許文献１に記載のような音声を利用するものや特許文献２に記載のような生体情報を利用するものが従来提案されている。 In view of this, as a personal identification number and password, there have conventionally been proposed ones that use voice as described in Patent Document 1 and those that use biological information as described in Patent Document 2.

特開２００５−３７７８１号公報JP 2005-37781 A 特開２００３−３０１５４号公報JP 2003-30154 A

しかしながら、特許文献１や特許文献２に示されたような、生体情報を利用するもの（生体の特徴に基づく個人認証方法）は、システムの構築に膨大な時間およびコストがかかるともに、個人の究極的な情報を利用するものであるために、この方式は一部の金融機関に利用されているにすぎない。 However, as shown in Patent Document 1 and Patent Document 2, a method using biometric information (a personal authentication method based on biometric features) takes an enormous amount of time and cost to construct a system, and is the ultimate of an individual. This method is only used by some financial institutions because it uses typical information.

本発明は、既存の認証システムを利用することができるとともに、第三者が容易に類推できない暗証番号を、カ−ド毎に簡単に創作（設定）できるとともに、その暗証番号を当該カ−ドの利用時に簡単に導き出せるようにした暗証番号創作具を提供しようとするものである。 In the present invention, an existing authentication system can be used, and a personal identification number that cannot be easily guessed by a third party can be easily created (set) for each card. It is intended to provide a PIN number creation tool that can be easily derived when using.

A square grid in the vertical direction and b square grids in the horizontal direction are drawn, which are separated by a directional ruled line and a plurality of equally spaced horizontal ruled lines. The card insert has the same number of grids of the same size as the character card in the transparent material portion in the vertical and horizontal directions, and each square-shaped grid on the surface of the character card. The characters are written in a predetermined order, and numerals are written on each square-shaped square drawn on the surface of the transparent material of the card insertion portion.

また、少なくとも一面が透明材で形成されたカ−ドの挿入体と同カ−ド挿入体に挿入可能な文字カ−ドとからなり、上記文字カ−ドの表面一杯に、ａ個の縦方向の正方形形状のマス目とｂ個の横方向の正方形形状のマス目とが描かれ、上記カ−ド挿入体の透明材の部分が上記文字カ−ドよりも縦方向および横方向に上記マス目の少なくとも一つに相当する寸法だけ広い表面積に形成されるとともに、その表面に、上記正方形形状のマス目と同一形状の、少なくともａ＋ｍ個の縦方向の正方形形状のマス目と少なくともｂ＋ｎ個の横方向の正方形形状のマス目とが描かれ、上記文字カ−ドの表面の各正方形形状のマス目に文字が所定の順序で表記され、上記カ−ド挿入部の透明材の表面に描かれた各正方形形状の各マス目に数字が表記され、上記文字カ−ドの表面の各正方形形状のマス目に表記された文字と、上記カ−ド挿入部の透明材の表面上の各正方形形状の各マス目に表記された数字との対応により、暗証番号を創作できるようにした点を特徴とする。 In addition, a card insertion body formed of a transparent material on at least one surface and a character card that can be inserted into the card insertion body. Square squares in the direction and b square squares in the horizontal direction are drawn, and the transparent material portion of the card insert is above and below the character card in the vertical and horizontal directions. The surface is formed with a large surface area by a size corresponding to at least one of the squares, and has at least a + m square squares in the vertical direction and at least b + n having the same shape as the square squares on the surface. Are drawn in a predetermined order on the surface of the transparent material of the card insertion portion. A number is written on each square of each square shape drawn, and the top By the correspondence between the characters written on each square-shaped cell on the surface of the character card and the numbers written on each square-shaped cell on the surface of the transparent material of the card insertion part, It is characterized by the ability to create a password.

また、上記文字カ−ドが、上記カ−ド挿入体の内部で縦方向および横方向に移動可能に挿入されていることを特徴とする。 Further, the character card is inserted inside the card insertion body so as to be movable in the vertical direction and the horizontal direction.

さらに、上記文字カ−ドの表面の各正方形形状のマス目に表記される文字が五十音順であり、また上記カ−ド挿入部の透明材の表面に描かれた各正方形形状の各マス目に表記された数字がアトランダム状であることを特徴とする。 Furthermore, the characters written on each square-shaped square on the surface of the character card are in the order of the Japanese syllabary, and each of the square shapes drawn on the surface of the transparent material of the card insertion portion. The numbers written in the grids are at random.

さらにまた、上記カ−ド挿入部が、携帯式カ−ドホルダ−であることを特徴とする。 Furthermore, the card insertion portion is a portable card holder.

上記文字カ−ドの表面の各正方形形状のマス目に表記された文字を上記カ−ド挿入体の透明材を通じて読み取り、そのマス目に重合するカ−ド挿入体の表面上のマス目に表記された数字と上記文字とを対応させることにより、暗証番号を創作できる。
また、同様の手法により、その暗証番号を当該カ−ドの利用時に簡単に導き出すことができる。
さらに、カ−ド挿入部を携帯式カ−ド入れ（の一部）で構成するとき、この暗証番号創作具とカ−ドとを常に同時に携帯できて便利である。 The character written on each square-shaped cell on the surface of the character card is read through the transparent material of the card insert, and the cell on the surface of the card insert is polymerized. A password can be created by associating the written numbers with the above characters.
In addition, the password can be easily derived at the time of using the card by the same method.
Furthermore, when the card insertion part is constituted by a portable card holder (part of it), it is convenient that the PIN code creating tool and the card can always be carried at the same time.

以下、本発明を図に示す実施形態により具体的に説明する。
図１において、符号１は文字カ−ドを示しており、この文字カ−ド１の表面一杯に、等間隔の複数本の縦方向の罫線と等間隔の複数本の横方向の罫線とで区切られて縦方向に５個（ａ個）の正方形形状のマス目と横方向に１０個（ｂ個）の正方形形状のマス目とが描かれている。そして、これらの各マス目に、図示の通り、右側の列から縦方向に「あ」「い」・・・・の文字が、五十音順に印字（印刷）され、残余の区画には、「−」、「半濁音」、「濁音」が印字（印刷）されている。ここで各文字は、この実施形態では、各正方形形状の区画の左側に印字されている。また、や行の「い」と「え」とはあ行の「い」、「え」と重合するので、この例ではここに「ちゃ」と「▲ハート▼」を印字してある。
文字カ−ド１に印字する文字を五十音順としたのは、所望の文字の印字されている位置の発見を容易にするためであり、五十音順に代えて「いろは」順としても良いことはいうまでもない。文字の印字順序はこれに限るものではない。
文字カ−ド１には同カ−ドの操作用のつまみ３が取り付けられている。 Hereinafter, the present invention will be specifically described with reference to embodiments shown in the drawings.
In FIG. 1, reference numeral 1 denotes a character card. The character card 1 is filled with a plurality of equally spaced vertical ruled lines and equally spaced horizontal ruled lines. Divided into 5 (a) square-shaped squares in the vertical direction and 10 (b) square-shaped squares in the horizontal direction. And, as shown in the figure, the letters “A”, “I”,... Are printed (printed) in the alphabetical order in the vertical direction from the right column, as shown in the figure. "-", "Semi-sound" and "sound" are printed (printed). Here, each character is printed on the left side of each square-shaped section in this embodiment. Also, “I” and “E” on the second line overlap with “I” and “E” on that line, so in this example, “Cha” and “▲ Heart” are printed here.
The reason that the characters printed on the character card 1 are arranged in the order of the Japanese syllabary is to facilitate the discovery of the position where the desired character is printed. It goes without saying that it is good. The character printing order is not limited to this.
The character card 1 is provided with a knob 3 for operating the card.

図２はカ−ド挿入体２を示している。このカ−ド挿入体２は表面が透明材２ａで形成されている。そしてその透明材２ａに文字カ−ド１と同じ寸法のマス目が縦方向および横方向にそれぞれ同じ数表記されている。そして、この各マス目（カ−ド挿入体２の透明材の表面に描かれた各正方形形状の各マス目）に、数字が、この実施形態では、順序不定に印字（印刷）されている。ここで各数字は、この実施形態では、正方形形状の各マス目の右側に印字されている。 FIG. 2 shows the card insert 2. The surface of the card insert 2 is formed of a transparent material 2a. The same number of squares having the same dimensions as the character card 1 are written on the transparent material 2a in the vertical and horizontal directions. In each of the squares (square squares drawn on the surface of the transparent material of the card insertion body 2), numbers are printed (printed) in an unordered order in this embodiment. . In this embodiment, each number is printed on the right side of each square-shaped square.

カ−ド挿入体２の本体部２ｂは薄い合成樹脂製シ−トからなり、その表面に透明材２ａがその左右両側端縁部と下端縁部とを本体部２ｂに溶着されて取り付けられている。符号２ｃは溶着部分を示す。透明材２ａの上端縁と本体部２ｂとの間には、文字カ−ド１の挿入口２ｄが形成されている。つまりカ−ド挿入体２は、表面が透明材２ａからなりその内側に透明材２ａからなるポケットを有する構成となっていて、このポケットに文字カ−ドが挿入できる構成となっている。ポケットに文字カ−ド１が挿入された時、文字カ−ド１の文字は挿入体２の透明材部分を通じて読み取ることが可能である。 The main body 2b of the card insertion body 2 is made of a thin synthetic resin sheet, and a transparent material 2a is attached to the surface of the card insert 2 by welding the left and right side edges and the lower edge to the body 2b. Yes. Reference numeral 2c indicates a welded portion. An insertion slot 2d for the character card 1 is formed between the upper end edge of the transparent material 2a and the main body 2b. That is, the card insertion body 2 has a structure in which the surface is made of the transparent material 2a and has a pocket made of the transparent material 2a on the inside thereof, and a character card can be inserted into this pocket. When the character card 1 is inserted into the pocket, the characters of the character card 1 can be read through the transparent material portion of the insert 2.

図３は使用状態の一例を示す。
図３の使用状態では、文字カ−ド１はカ−ドの挿入体２内に、右寄りで且つ最上のところに位置する状態、つまり文字カ−ド１の「あ」のマス目とカ−ド挿入体２の透明材の「１」のマス目とが重合する状態で挿入されている。 FIG. 3 shows an example of the usage state.
In the use state of FIG. 3, the character card 1 is located in the card insertion body 2 on the right side and at the uppermost position, that is, the “A” cell and the card of the character card 1. It is inserted in a state in which the “1” grid of the transparent material of the core insert 2 is polymerized.

この使用状態では、挿入体２の透明材部分を通じて、最右側欄は、上方のマス目から、文字カ−ド１上の文字「あ」と挿入体２の透明材上の数字「１」とを同時に読み取ることができる。同様に、以下順に、「い」と「２」とを、「う」と「３」とを、「え」と「４」とを、「お」と「５」とをそれぞれ同時に読み取ることができる。
右から２欄目では、上方のマス目から、文字「か」と数字「０」とを、以下順に、「き」と「３」とを、「く」と「２」とを、「け」と「５」とを、「こ」と「４」とをそれぞれ同時に読み取ることができる。
３欄目以降においても、図示の通り、各マス目において、文字と数字とをそれぞれ同時に読み取ることができる。 In this state of use, through the transparent material portion of the insert 2, the rightmost column shows the character “A” on the character card 1 and the number “1” on the transparent material of the insert 2 from the upper cell. Can be read simultaneously. Similarly, “I” and “2”, “U” and “3”, “E” and “4”, “O” and “5” can be read simultaneously in the following order. it can.
In the second column from the right, from the top cell, the character “ka” and the number “0”, “ki” and “3”, “ku” and “2”, “ke” And “5” and “ko” and “4” can be read simultaneously.
Also in the third column and thereafter, as shown in the figure, letters and numbers can be simultaneously read in each square.

次ぎに、図３に示す状態での、暗証番号の創作ないし導き出し操作について説明する。キャッシュカ−ドなどの利用者は、メモを別に用意し、そのメモに、Ａ銀行：夫、Ｂ銀行：長男、Ｃクレジット会社：長女というように、銀行毎にあるいはクレジットカ−ド毎に、それぞれ対応する、符牒を予め記載しておく。なお、このメモは錯誤などによる誤操作を防止するため念のために用意するものであって、記憶によりこのようなメモを必要としない場合は、メモは必要としない。符牒の内容は本人にしか分からないものが望ましい。 Next, an operation for creating or deriving a personal identification number in the state shown in FIG. 3 will be described. Users such as cash cards prepare separate memos, which correspond to each bank or credit card, such as A bank: husband, B bank: eldest son, C credit company: eldest daughter. The sign is written in advance. This memo is prepared as a precaution to prevent erroneous operations due to mistakes, etc. If the memo is not necessary due to memory, the memo is not required. It is desirable that the contents of the sign be understood only by the person himself / herself.

夫の名前が「はじめ」であったとすると、図３の状態で、「は」は６、「し」は４、「”」は６、「め」は０に対応するから、「はじめ」は４桁の数字（６４６０）に変換できる。このようにして得られた４桁の数字（６４６０）をＡ銀行に暗証番号として登録する。 If the husband's name is “beginning”, in the state of FIG. 3, “ha” corresponds to 6, “shi” corresponds to 4, “” ”corresponds to 6, and“ me ”corresponds to 0. It can be converted to a 4-digit number (6460). The 4-digit number (6460) obtained in this way is registered as a personal identification number in Bank A.

キャッシュカ−ドの利用の際、メモとこの暗証番号創作具を所有しておれば、暗証番号を忘れていても、この暗証番号創作具を上述の暗証番号登録時と同様に操作して、つまり、Ａ銀行において、「夫」なる符牒から名前「はじめ」を連想し、「はじめ」から暗証番号（６４６０）を導き出す。夫の名前「はじめ」から「６４６０」という４桁の暗証番号に変換できるのは本人だけであるから、キャッシュカ−ドが悪用されるおそれはなくなる。 If you have a memo and this PIN code creator when using the cash card, even if you have forgotten the PIN code, you can operate the PIN code generator in the same way as when registering the PIN code. The bank A associates the name “start” with the sign “husband” and derives the personal identification number (6460) from the “start”. Since only the person can convert the husband's name “start” to the four-digit password “6460”, there is no possibility that the cash card is misused.

Ｂ銀行のキャッシュカ−ドやＣクレジット会社のカ−ドについても同様である。
暗証番号としては４桁の場合が一般的である。夫、長男、長女などの名前が３文字の時、この暗証番号創作具で上述の操作を行うと暗証番号は３桁ものとなる。そのような場合は、メモに長男の後にたとえば「か」なる補助記号を記入しておき、「か」に対応する数字を暗証番号創作具で読み取って長男の名前から得られた３桁の数字の最後にこの数字を追加することで、４桁の暗証番号を創作することができる。 The same applies to the bank B card and the C credit card.
As a personal identification number, a 4-digit case is common. When the names of husband, eldest son, eldest daughter, etc. are three characters, the above-mentioned operation is performed with this PIN code creator, and the PIN number becomes three digits. In such a case, write a supplementary symbol such as “ka” after the eldest son in the memo, and read the number corresponding to “ka” with the PIN code creator to create a three-digit number obtained from the eldest son's name. You can create a 4-digit PIN by adding this number to the end of

このようにして、文字カ−ド１の各正方形形状のマス目に記載された文字と、カ−ド挿入体２の透明材上の各正方形形状の各マス目に記載された数字との対応により、暗証番号を創作することができる。 In this way, the correspondence between the characters written on each square-shaped square of the character card 1 and the numbers written on each square-shaped square on the transparent material of the card insert 2 Thus, a password can be created.

次ぎに第２実施形態について説明する。
この第２実施形態においても文字カ−ド１は先に説明した実施形態（第１実施形態）のものと同じものであるが、カ−ド挿入体２は図４に示す構成となっている。
図４に示す通り、カ−ド挿入体２は表面が透明材２ａで形成されており、このカ−ド挿入体２の透明材２ａの部分は、文字カ−ド１の表面よりも縦方向および横方向に、それぞれマス目の少なくとも一つ分に相当する寸法だけ広い表面積を有する構成となっていて、その表面に、少なくともａ＋ｍ個の縦方向の（正方形形状の）マス目と、少なくともｂ＋ｎ個の横方向の（正方形形状の）マス目とが描かれている。そして、この各マス目（カ−ド挿入体２の透明材の表面に描かれた各正方形形状の各マス目）に、数字が、この実施形態では、順序不定に印字（印刷）されている。ここで各数字は、この実施形態では、各正方形形状のマス目の右側に印字されている。 Next, a second embodiment will be described.
Also in the second embodiment, the character card 1 is the same as that of the above-described embodiment (first embodiment), but the card insert 2 has a configuration shown in FIG. .
As shown in FIG. 4, the card insert 2 has a surface formed of a transparent material 2 a, and the transparent material 2 a portion of the card insert 2 is longer than the surface of the character card 1. In the horizontal direction, the surface area has a large surface area corresponding to at least one dimension corresponding to at least one grid, and at least a + m vertical (square-shaped) grids and at least b + n are formed on the surface. A number of horizontal (square-shaped) squares are drawn. In each of the squares (square squares drawn on the surface of the transparent material of the card insertion body 2), numbers are printed (printed) in an unordered order in this embodiment. . In this embodiment, each number is printed on the right side of each square-shaped square.

文字カ−ド１をカ−ド挿入体２内に、右寄りで且つ最上のところに位置させると、第１実施形態の場合と同様の操作により暗証番号を得ることができる。
文字カ−ド１をこの状態から１マス目下方に移動させた位置に移動させると、別の暗証番号を創作することができる。
また最初の位置から左方向に１マス目移動させたり、斜め方向に１マス目移動させたりして、それぞれ別の暗証番号を作成することも可能となる。 When the character card 1 is positioned in the card insertion body 2 on the right side and at the uppermost position, the password can be obtained by the same operation as in the first embodiment.
If the character card 1 is moved to a position moved downward from the first square from this state, another password can be created.
It is also possible to create different personal identification numbers by moving the first grid to the left from the initial position or by moving the first grid in the diagonal direction.

この実施形態では、カ−ド挿入体２の透明材に表記されるマス目の数が文字カ−ド１に表記されたマス目の数よりも、縦、横それぞれ＋１となっているが、それよりも多くしておくと、同様の操作でさらに多数の暗証番号の創作が可能なことは明らかであろう。
また、文字カ−ド１に表記されるマス目を、横１０以上、縦５以上として、５０音文字だけで埋まらないマス目の数を多くし、そのマス目に絵模様〔たとえば「▲ハート▼」（ハ−トマ−ク）、「？」〕などの補助記号を表記しておき、これらの補助記号を上述の「か」に代えるようにしてもよい。 In this embodiment, the number of grids written on the transparent material of the card insert 2 is +1 in both the vertical and horizontal directions than the number of grids written on the character card 1. It will be clear that a larger number of passwords can be created with the same operation if the number is larger than that.
In addition, the squares described in the character card 1 are 10 or more in width and 5 or more in length, and the number of squares that are not filled with only 50 syllabary characters is increased. Auxiliary symbols such as “▼” (heart mark) and “?”] May be written, and these auxiliary symbols may be replaced with the above-mentioned “ka”.

次に図５に文字カ−ドの変形例を示す。
図５に示す文字カ−ド５は、横方向長さが図１に示した文字カ−ド１の２倍の長さ＋糊代の帯状の紙片５ａの全表面に、図１と同じように複数本の縦、横方向の罫線で区切って縦、横方向に複数個のマス目を描き、これらの各マス目に、上述の実施形態のものと同様に文字を、この例では五十音を２順分並べて表記する。ついで上記糊代を接合し、無端状体のものを形成し、これを縦方向の適宜なところで罫線に沿って２箇所で折り曲げて扁平状に変形して、図１の文字カード１と同じ横方向長さの平面状のカ−ド形状に形成したものである。
この変形例のカ−ド５の場合、折り曲げる位置を変えることにより、多種類の文字カ−ドを簡単に製作することが可能となる。 Next, FIG. 5 shows a modification of the character card.
The character card 5 shown in FIG. 5 has the same length as that of FIG. 1 on the entire surface of the strip-shaped paper piece 5a whose lateral length is twice the length of the character card 1 shown in FIG. A plurality of squares are drawn in the vertical and horizontal directions separated by a plurality of vertical and horizontal ruled lines, and characters similar to those of the above-mentioned embodiment are drawn in these squares. Two sounds are listed side by side. Next, the above paste margin is joined to form an endless body, which is bent at two places along a ruled line at an appropriate length in the vertical direction and deformed into a flat shape, and the same horizontal as the character card 1 in FIG. It is formed in a planar card shape having a length in the direction.
In the case of the card 5 of this modified example, it is possible to easily produce many types of character cards by changing the folding position.

また、変形例として文字と数字とを異なる色彩で印字した例を挙げることができる。この変形例では、使用時に文字と数字とが異なる色彩で表示されるので、使用時の煩わしさを抑制できるという効果を期待できる。 Moreover, the example which printed the character and the number with a different color as a modification can be given. In this modification, since characters and numbers are displayed in different colors when used, it is possible to expect an effect that the troublesomeness during use can be suppressed.
