The plurality of light emitting units 14 a, 14 b, and 14 c emit light having different wavelengths, and the wavelengths are selected according to the reflection characteristics of the identifier 22. Note that four or more light emitting units may be provided. The light receiving unit 16 may be configured by providing a corresponding light receiving element for each light emitting unit, or may receive light from all the light emitting units with one light receiving element. Since the detection device 10 has such a configuration, it can be determined whether or not the ink applied to the identification body 22 is a predetermined ink, as will be described later.
　検知装置１０は、識別体２２が付された被検知体２０を収容するところが設けられたものでも、又は、ペン型のもので識別体２２をなぞることで情報を判定（たとえば真贋を検知）するものであってもよい。 The detection device 10 determines the information (for example, detects authenticity) by tracing the identification body 22 with a pen-shaped one provided with a place to accommodate the detected body 20 to which the identification body 22 is attached. It may be a thing.
　検知装置１０は、図４に示すように、所定の情報を一次元または二次元のコードに変換したものの情報を読み取る読み取り部１８をさらに含んでもよい。所定の情報を一次元のコードに変換したものとしては、たとえば線の太さによって数値や文字をコード化したバーコードを挙げることができる。所定の情報を二次元のコードに変換したものとしては、たとえばドットを縦横に配列したコード（ＱＲコード（登録商標）など）を挙げることができる。読み取り部１８は、たとえば、バーコードスキャナなど公知の読み取り手段を適用することができる。検知装置１０に読み取り部１８が設けられている場合には、後述のように識別体２２が所定の情報を一次元または二次元のコードに変換した部分をさらに含む際に、特に有用である。 As shown in FIG. 4, the detection device 10 may further include a reading unit 18 that reads information obtained by converting predetermined information into a one-dimensional or two-dimensional code. Examples of the information obtained by converting the predetermined information into a one-dimensional code include a bar code in which numerical values and characters are coded according to the thickness of the line. Examples of the information obtained by converting predetermined information into a two-dimensional code include a code (QR code (registered trademark)) in which dots are arranged vertically and horizontally. For the reading unit 18, for example, a known reading unit such as a barcode scanner can be applied. When the reading unit 18 is provided in the detection device 10, it is particularly useful when the identification body 22 further includes a portion obtained by converting predetermined information into a one-dimensional or two-dimensional code as will be described later.
　検知装置１０において、光が出入する部分を光ファイバーを通じて行ってもよい。これにより、光を特定の領域に収束させて出射することができると共に、反射光をより確実に捕捉することができる。 In the detection apparatus 10, a portion where light enters and exits may be performed through an optical fiber. Thereby, the light can be converged and emitted to a specific region, and the reflected light can be captured more reliably.
　また、検知装置１０は、人にとって固有の情報（たとえば指紋、虹彩、静脈の形態）を認識する認識手段があってもよい。これによれば、検知装置１０が特定の者のみ扱うことが許可されている場合において、その者かどうかを判断することができる。また、識別体２２が付されている物に何らかの処理（たとえば当該被検知体の分解、修理）をできる者かどうかを判断させてもよい。 Further, the detection device 10 may have a recognition means for recognizing information unique to a person (for example, fingerprint, iris, vein form). According to this, when the detection apparatus 10 is permitted to handle only a specific person, it can be determined whether or not the person is that person. Moreover, you may make it judge whether it is a person who can perform a certain process (for example, decomposition | disassembly of the said to-be-detected body, repair) to the thing to which the identification body 22 is attached | subjected.
　３．識別体
　識別体２２について説明する。識別体２２には、基体にインキが付されて構成される。インキは識別体２２の基体にたとえば印刷や塗布により付される。インキは日本国特許出願の特願２００８−１９３２８３号に開示された技術等を適用することができる。インキは、少なくとも３つの異なる波長域において異なる反射特性を有する。インキは、特に、図３に示すように、波長の短い順に、第１の波長領域（たとえば光の反射率が１０％以下の波長領域）Ａ１と、第２の波長領域（たとえば光の反射率が４３~７３％、好ましくは５５~６５％の波長領域）Ａ２と、第３の波長領域（たとえば光の反射率が１３~４３％、好ましくは２３~３３％の波長領域）とを有するものが好適である。ここで、第３の波長領域の反射率は、第２の波長領域の反射率より３０~７０％の範囲にあることが好適である。特願２００８−１９３２８３号に開示された技術によれば、近赤外領域または赤外領域にこのような波長領域を作ることができる。第１の波長領域Ａ１から第３の波長領域Ａ３は連続していても、連続していなくてもよい。 3. Discriminator The discriminator 22 will be described. The identification body 22 is configured by applying ink to a base. The ink is applied to the base of the identification body 22 by, for example, printing or coating. For the ink, the technology disclosed in Japanese Patent Application No. 2008-193283, which is a Japanese patent application, can be applied. The ink has different reflection characteristics in at least three different wavelength ranges. In particular, as shown in FIG. 3, the ink has a first wavelength region (for example, a wavelength region where the reflectance of light is 10% or less) A1 and a second wavelength region (for example, the reflectance of light) in order of decreasing wavelength. Having a wavelength range of 43 to 73%, preferably 55 to 65%) A2 and a third wavelength range (for example, a wavelength range of 13 to 43%, preferably 23 to 33% of light reflectivity) Is preferred. Here, the reflectance of the third wavelength region is preferably in the range of 30 to 70% than the reflectance of the second wavelength region. According to the technique disclosed in Japanese Patent Application No. 2008-193283, such a wavelength region can be formed in the near infrared region or the infrared region. The first wavelength region A1 to the third wavelength region A3 may or may not be continuous.
　なお、この場合に、第１の発光部１４ａは第１の波長領域Ａ１にある波長の光を発光するものとし、第２の発光部１４ｂは第２の波長領域Ａ２にある波長の光を発光するものとし、第３の発光部１４ｃは、第３の波長領域Ａ３にある波長の光を発光するものとすることができる。 In this case, the first light emitting unit 14a emits light having a wavelength in the first wavelength region A1, and the second light emitting unit 14b emits light having a wavelength in the second wavelength region A2. It is assumed that the third light emitting unit 14c emits light having a wavelength in the third wavelength region A3.
　識別体２２の形状は特に限定されないが、ラベル状のものとすることで取扱いが容易となる。識別体２２の基体は、たとえば紙、樹脂フィルム、金属シート、繊維、皮革、ガラスなどからなることができる。 The shape of the identification body 22 is not particularly limited, but handling can be facilitated by using a label. The base of the identification body 22 can be made of, for example, paper, a resin film, a metal sheet, fiber, leather, glass, or the like.
　また、図４（Ａ）に示すように、識別体２２は、上記のインキを含んで構成される第１の識別部分と、所定の情報を一次元または二次元のコードに変換した第２の識別部分とを含むものであってもよい。所定の情報を一次元のコードに変換したものとしては、たとえば線の太さによって数値や文字をコード化したバーコードを挙げることができる。所定の情報を二次元のコードに変換したものとしては、たとえばドットを縦横に配列したコード（ＱＲコード（登録商標）など）を挙げることができる。これにより、たとえば、第１の識別部分を真贋判定のための情報を付与した部分とし、第２の識別部分に所定の情報（履歴情報、製造情報、特性情報、価格情報（価格、値下げ率）、配送情報など）を付与した部分とすることができ、識別体２２自体の情報の記憶量を向上させることができる。 As shown in FIG. 4A, the identification body 22 includes a first identification portion including the above-described ink, and a second obtained by converting predetermined information into a one-dimensional or two-dimensional code. And an identification part. Examples of the information obtained by converting the predetermined information into a one-dimensional code include a bar code in which numerical values and characters are coded according to the thickness of the line. Examples of the information obtained by converting predetermined information into a two-dimensional code include a code (QR code (registered trademark)) in which dots are arranged vertically and horizontally. Thereby, for example, the first identification part is a part to which information for authenticity determination is given, and predetermined information (history information, manufacturing information, characteristic information, price information (price, price reduction rate) is assigned to the second identification part. , Delivery information, etc.), and the amount of information stored in the identifier 22 itself can be improved.
　さらに、識別体２２は、図４（Ｂ）に示すように、上記のインキが付された部分と、上記のインキではないインキが付された部分とを含むことができる。これらの部分は、たとえば、ライン状のものや、ドット状に付してもよい。これらの部分の配列や組み合わせに何らかの情報（履歴情報、製造情報、特性情報、価格情報（価格、値下げ率）、配送情報など）を付与することができる。 Furthermore, as shown in FIG. 4B, the identification body 22 can include a portion to which the above ink is applied and a portion to which an ink other than the above ink is applied. These portions may be provided in a line shape or a dot shape, for example. Some information (history information, manufacturing information, characteristic information, price information (price, price reduction rate), delivery information, etc.) can be given to the arrangement or combination of these parts.
　具体的には、３本のインキが付された部分がある場合において、上記のインキの部分、上記のインキでない部分および上記のインキの部分の並びの組み合わせであれば、日本製であることを意味し、上記のインキの部分、上記のインキでない部分および上記のインキでない部分の並びの組み合わせであれば、欧州製であることを意味させるなどすることができる。この意味づけは、適宜、使用をする者が決めることができる。また、順序も考慮することで、より多くの情報を付与することができる。さらに、この組み合わせに基づき、所定の組み合わせであれば真と判定し、そうでなければ偽と判定するような真贋判定としてもよい。これにより、セキュリティー性をより向上させることができる。 Specifically, in the case where there are three ink-applied parts, if the combination of the above-mentioned ink part, the above-mentioned non-ink part and the above-described ink part is combined, it is made in Japan. In other words, if the combination of the above-described ink portion, the above-mentioned non-ink portion, and the above-not-ink portion is combined, it can mean that the portion is made in Europe. This meaning can be appropriately determined by the person who uses it. Also, more information can be given by considering the order. Further, based on this combination, authenticity determination may be made such that a predetermined combination is determined to be true, and otherwise it is determined to be false. Thereby, security can be further improved.
　また、識別体にＲＦＩＤ（Ｒａｄｉｏ　Ｆｒｅｑｕｅｎｃｙ　Ｉｄｅｎｔｉｆｉｃａｔｉｏｎ）を組み込むことで、より情報量を記憶させることができる。 Also, by incorporating RFID (Radio Frequency Identification) into the identifier, the amount of information can be stored more.
　４．情報判定の動作
　情報判定の動作例として、真贋判定を例にとり、その動作例を説明する。 4). Information Determination Operation As an example of information determination operation, an example of authenticity determination will be described, and an example of the operation will be described.
　識別体２２のインキが第１~第３の異なる３つの反射特性（たとえば反射率）を有する場合の例を説明する。ここで、第１の発光部１４ａは、識別体のインキの第１の反射特性に対応した波長の光を発光し、第２の発光部１４ｂはその第２の反射特性に対応した波長の光を発光し、第３の発光部１４ｃはその第３の反射特性に対応した波長の光を発光する例とする。 An example in which the ink of the identification body 22 has first to third different three reflection characteristics (for example, reflectance) will be described. Here, the first light emitting unit 14a emits light having a wavelength corresponding to the first reflection characteristic of the ink of the identification body, and the second light emitting unit 14b has light having a wavelength corresponding to the second reflection characteristic. The third light emitting unit 14c emits light having a wavelength corresponding to the third reflection characteristic.
　まず、第１の発光部１４ａを識別体２２に向けて発光させ、識別体２２で反射したその光を受光部１６で受光し、第１の発光部１４ａの光の波長域における識別体２２の反射特性を導出する。受光部１６がフォトダイオードの場合には、反射光を受光したときのフォトダイオードの出力電圧に基づいて反射特性（反射光の強度）を導出することができる。次に、第２の発光部１４ｂを識別体２２に向けて発光させ、識別体２２で反射したその光を受光部１６で受光し、第２の発光部１４ｂの光の波長域における識別体２２の反射特性を導出する。次に、第３の発光部１４ｃを識別体２２に向けて発光させ、識別体２２で反射したその光を受光部１６で受光し、第３の発光部１４ｃの光の波長域における識別体２２の反射特性を導出する。これら３つの波長域における識別体２２の反射特性に基づき、所定の特性を有するインキかどうかを判定し、その識別体２２が付されたものの真贋を判定する。つまり、検知した反射特性のパターンが所定の反射特性のパターンであれば、真と判断し、所定の反射特性のパターンでなければ偽と判定する。また、いずれかの発光部による光の反射率を特定して、その反射率とその他の発光部による光の反射率との相対値に基づき判定してもよい。 First, the first light emitting unit 14a emits light toward the discriminating body 22, the light reflected by the discriminating body 22 is received by the light receiving unit 16, and the light of the discriminating body 22 in the wavelength range of light of the first light emitting unit 14a is received. Derivation of reflection characteristics. When the light receiving unit 16 is a photodiode, the reflection characteristic (intensity of the reflected light) can be derived based on the output voltage of the photodiode when the reflected light is received. Next, the second light emitting unit 14b emits light toward the discriminating body 22, the light reflected by the discriminating body 22 is received by the light receiving unit 16, and the discriminating body 22 in the wavelength range of light of the second light emitting unit 14b. Deriving the reflection characteristics of. Next, the third light emitting unit 14c emits light toward the discriminating body 22, the light reflected by the discriminating body 22 is received by the light receiving unit 16, and the discriminating body 22 in the wavelength region of light of the third light emitting unit 14c. Deriving the reflection characteristics of. Based on the reflection characteristics of the discriminator 22 in these three wavelength regions, it is determined whether the ink has a predetermined characteristic, and the authenticity of the ink to which the discriminator 22 is attached is determined. That is, if the detected reflection characteristic pattern is a predetermined reflection characteristic pattern, it is determined to be true, and if it is not a predetermined reflection characteristic pattern, it is determined to be false. Further, the reflectance of light by any one of the light emitting units may be specified, and the determination may be made based on the relative value between the reflectance and the reflectance of light by the other light emitting units.
　なお、反射特性は、その受光部１６が受光した光を電圧に変換し、その出力電圧に基づき反射の度合いを導出することができる。 The reflection characteristic can be obtained by converting the light received by the light receiving unit 16 into a voltage and deriving the degree of reflection based on the output voltage.
　真贋判定は、各出力電圧の比率をみることでより正確かつ精度よく行うことができる。なお、真贋判定は、マイクロコンピュータなどのよる公知の演算装置等を実現することができる。 Authenticity can be determined more accurately and accurately by looking at the ratio of each output voltage. The authenticity determination can be realized by a known arithmetic device such as a microcomputer.
　この第１の発光部１４ａから第３の発光部１４ｃの発光のサイクルは１回でもよいし、複数回でもよい。また、上記の例では、第１の発光部１４ａ、第２発光部１４ｂ、第３の発光部１４ｃの順で発光させる例を示したが、各発光部１４ａ，１４ｂ，１４ｃを発光させる順序はこれに限定されず、とり得る発光の順序のすべてが適用可能である。 The light emission cycle from the first light emitting unit 14a to the third light emitting unit 14c may be one time or multiple times. In the above example, the example in which the first light emitting unit 14a, the second light emitting unit 14b, and the third light emitting unit 14c emit light is shown. However, the order in which the light emitting units 14a, 14b, and 14c emit light is described. The present invention is not limited to this, and all possible light emission sequences are applicable.
　また、検知装置１０と被検知体２０との間において、光導波路を設けて、光を識別体２２に導くとともに、反射光を光導波路を通じて受光部に導いてもよい。 Further, an optical waveguide may be provided between the detection device 10 and the detection target 20, and the light may be guided to the identification body 22, and the reflected light may be guided to the light receiving unit through the optical waveguide.
　なお、真贋判定の結果を表示する表示部を設けてもよい。表示部は、公知の表示装置（たとえば液晶表示装置、ＬＥＤなどの可視域の発光体）を適用することができ、たとえば、真の場合にのみ、発光体（たとえば可視域のＬＥＤ）を発光させてもよい。また、真の場合と偽の場合とで、異なる光を発光させてもよい。 It should be noted that a display unit for displaying the result of the authenticity determination may be provided. For the display unit, a known display device (for example, a liquid crystal display device, a visible light emitter such as an LED) can be applied. May be. Different light may be emitted depending on whether it is true or false.
