【0001】
【発明の属する技術分野】
本発明は、銀行券、パスポート、有価証券、カード、印紙類等の偽造防止、改竄防止が必要とされる貴重印刷物に適用する真偽判別形成体に関するものである。
【0002】
【従来の技術】
銀行券、パスポート、有価証券、カード、印紙類等の貴重印刷物は、その性質上、偽造、変造されにくいことが要求される。この防止策として、これらの貴重印刷物の基材に、複数の穿孔で数字等を形成することは知られている。また、複数の穿孔を有する基材を傾けて観察することにより潜像画像を視認できるようにして真偽判別を行う技術も知られている。
【0003】
前者は、スイスの銀行券に用いられており、数字を穿孔によって表現している。また、孔の直径は、反射状態においては裸眼でそれらのなすパターンが見えない点に特徴を有する、 安全マークが、透過状態においては見える文書面のパターンを形成する複数個の孔からなる、偽造を防止するための安全マークを備える安全保管文書が開示されている(例えば、特許文献1参照)。
【0004】
【特許文献1】
特表2000−501036号公報(第2頁、第1−2図)
【0005】
後者は、基材を有し、該基材に形成され、背景部と特定のパターンから成る情報部とを形成する目視しにくい多数の微細な穿孔を有する真偽判別形成体であって、上記背景部を形成する穿孔と上記情報部を形成する穿孔とは、穿孔の形状、寸法及び配列方向の少なくとも一つ以上が異なるように形成されていることを特徴とする真偽判別形成体が開示されている(例えば、特許文献2参照)。
【0006】
【特許文献2】
特開2000−233561号公報(第2頁、第1−2図)
【0007】
また、特定のパターンで配列されて情報を付与する多数の微細穿孔が形成されたカード基材を有する微細穿孔カードであって、上記微細穿孔は、レーザ加工機により、上記カード基材に対して特定の傾斜角度で貫通して形成された穿孔であり、上記微細穿孔カードの一面側から光を上記微細穿孔カードに対して上記特定の傾斜角度と同じ角度で投光して、上記微細な穿孔を透過させることにより、上記情報がチェックされる構成であることを特徴とする微細穿孔カードが開示されている(例えば、特許文献3参照)
【0008】
【特許文献3】
特開2002−160477号公報(第2頁、第1図)
【0009】
また、異なった角度で貫通した穿孔で画像を形成することによって両眼視差によって画像が立体的に視認されることが考えられる。
【0010】
【発明が解決しようとする課題】
上記の従来技術は総じて、基材に穿孔によって数字等を形成するものや、基材に一部の穿孔の形状を異ならせて、透過光で傾けて観察した場合に潜像画像が視認されるものであった。特表2000−501036号公報は、穿孔によって数字等を形成しているだけであって、偽造防止技術としては単純で改良の余地があった。また、特開2000−233561号公報は、情報部と背景部を組み合わせることで、穿孔群の中に情報部を隠し入れる構成であるため、基材を透過光で傾けて観察したときに傾ける角度を深めなければ潜像画像が明瞭に出現されない恐れがあり、複数の潜像画像を形成することは困難であった。また、特開2002−160477号公報は、基材に複数の穿孔からなる穿孔群を設け、穿孔群の一部の穿孔を基材に対して斜めに開けて潜像画像を構成し、基材を透過光で観察することにより潜像画像を視認できるものであり、レーザを垂直に照射し、且つ、基材を水平方向に自動搬送するような大量生産ラインを構成することは容易であるが、基材に斜め穿孔を形成することは、加工機の構成が複雑となり、作製上困難であった。また、異なった角度で貫通した穿孔で画像を形成することによって両眼視差によって画像が立体的に視認されることが考えられるが、異なった角度で貫通した穿孔だけの構成では、鮮明な立体画像を得ることができなかった。
【0011】
以上のことから、本発明は前述した問題点を解決することを目的としたもので、基材に貫通する穿孔群からなる画像と、これらの穿孔と基材を貫通しない穿孔群からなる潜像画像を形成し、画像を形成する基材を貫通する穿孔位置と、潜像画像を形成する基材を貫通しない穿孔位置を対応して配置することによって、透過光で観察した場合に明瞭な潜像画像の出現、多方向から異なる潜像画像の出現、鮮明な立体的な潜像画像の出現がされることを見出した。よって、本発明は真偽判別効果の高い、改ざん、複製防止効果のある真偽判別形成体を提案するものである。
【0012】
また、第1の基材に貫通する穿孔群からなる画像と、これらの穿孔と第2の基材を貫通する穿孔群からなる潜像画像を形成し、画像を形成する第1の基材を貫通する穿孔位置と、潜像画像を形成する第2の基材を貫通する穿孔位置を対応して配置して、第1の基材と第2の基材を積層することによって、透過光で観察した場合に明瞭な潜像画像の出現、多方向から異なる潜像画像の出現、鮮明な立体的な潜像画像の出現がされることを見出した。よって、本発明は真偽判別効果の高い、改ざん、複製防止効果のある真偽判別形成体を提案するものである。

【発明の実施の形態】
本発明に係る真偽判別形成体の実施の形態を基づいて図面を参照して説明する。本発明の真偽判別形成体の特徴は基材に形成した2次元に配列された基材を貫通する穿孔により形成した穿孔群からなる画像と、基材に形成した2次元に配列された基材を貫通しない穿孔により形成した穿孔群からなる潜像画像を設け、潜像画像を形成する基材を貫通しない穿孔群の個々の穿孔位置は、画像を形成する基材を貫通する穿孔群の個々の穿孔位置に対応して配置されることによって、透過光で特定の観察方向から観察した場合に、基材を貫通しない穿孔により形成した潜像画像が観察可能とするものである。また、第1の基材に形成した2次元に配列された第1の基材を貫通する穿孔により形成した穿孔群からなる画像と、第2の基材に形成した2次元に配列された第2の基材を貫通する穿孔により形成した穿孔群からなる潜像画像及び第2の基材を貫通する穿孔により形成した穿孔群からなる第1の基材に形成した画像と同一の画像を設け、潜像画像及び同一の画像を形成する第2の基材を貫通する穿孔群の個々の穿孔位置は、画像を形成する第1の基材を貫通する穿孔群の個々の穿孔位置に対応して配置されることによって、透過光で特定の観察方向から観察した場合に、第2の記載に形成した潜像画像が観察可能とするものである。

図1に基材(1a)に画像(2a)を穿孔(3a)により形成した図及びそのX−X’断面図を示す。図1に示すように穿孔(3a)は基材を貫通している必要がある。図2に基材(1a)に潜像画像(2c)のみを穿孔(3c)により形成した図及びそのX−X’断面図を示す。図2に示すように穿孔(3c)は基材を貫通することなく、一定の深さ又は複数に定められた深さに形成する必要がある。図1及び図2に示した穿孔(3a)により形成した画像(2a)及び穿孔(3c)により形成した潜像画像(2c)が施された真偽判別形成体(4a)及びそのX−X’断面図を図3に示す。図3に示すように基材(1a)を貫通しない穿孔(3c)が、基材(1a)を貫通する穿孔(3a)に一部が重なるようにして規則的に配置される必要がある。この場合は、基材(1a)を貫通しない穿孔(3c)は、基材(1a)を貫通する穿孔(3a)に対して、左部に規則的に配置されているが、右部、上部又は下部等、つまり、基材(1a)を貫通する穿孔(3a)の周辺領域に対して一部重なるように規則的に配置されていれば良い。

図5(a)は、真偽判別形成体(4a)を反射光で観察した場合、図5(b)は、真偽判別形成体(4a)を基材に対して垂直方向から透過光で観察した場合の図を示す。図5(a)に示すように、潜像画像(2c)を形成する基材(1a)を貫通しない穿孔(3c)は、基材と同じ色であるため、反射光で観察した場合は、観察者は、基材(1a)を貫通する穿孔による画像(2a)だけを認識することになる。また、図5(b)に示すように、真偽判別形成体(4a)を基材に対して垂直方向から透過光で観察した場合は、観察者は、基材(1a)を貫通する穿孔(3a)を透過してくる光を強く感じるため、基材(1a)を貫通する穿孔(3a)による画像(2a)をだけを認識することになる。上記どちらの場合も、潜像画像(2c)を視認することができない。
【0033】
図6は、真偽判別形成体(4a)を、図4に示したX方向から透過光で観察した場合の図を示す。図6に示すように基材(1a)を貫通する穿孔(3a)による画像(2a)内に、基材(1a)を貫通しない穿孔(3c)による潜像画像(2c)をはっきりと視認することができる(この場合は数字の1である)。これは、基材(1a)に設けた潜像画像(2c)を構成する穿孔(3c)が、基材(1a)に設けた画像(2a)を構成する穿孔(3a)に一部重なるように規則的に配置されているため、図4に示すような透過光が観察できる方向から観察することによって、穿孔(3a)と穿孔(3c)が重なっているように視認される領域からは透過光量が強く、穿孔(3a)と穿孔(3c)が重なっていない領域からはほとんど透過光量が認識されないため、このコントラストの差によって、図6に示したように画像(2a)内に、潜像画像(2c)を視認することができる。
【0034】
観察可能な方向については、図7に示すように潜像画像(2c)を構成する基材(1a)を貫通しない穿孔(3c)と、画像(2a)を構成する基材(1a)を貫通する穿孔(3a)との配置規則に依存する。つまり、図7のX−X’断面図に示すように、画像(2a)を構成する基材(1a)を貫通する穿孔(3a)に対して、潜像画像(2c)を構成する基材(1a)を貫通しない穿孔(3c)がY1側に規則的に配置された場合は、X1方向に傾けて透過光で観察することが必要であり、Y2側に規則的に配置された場合は、X2方向に傾けて透過光で観察することが必要である。また、基材の表裏どちらの面からも上記記載の同一方向から観察可能である。
【0035】
次に、透過光で異なる4方向から、それぞれ異なる潜像画像が見える真偽判別形成体(4b)を基材を貫通しない穿孔が形成されていない面から見た場合について図9に示す。基材には図1に示した画像を穿孔によって形成した基材を用いる。透過光で異なる4方向から、それぞれ異なる画像が視認できるようにするためには、基材を貫通しない穿孔と基材を貫通する穿孔に規則性を持たせる必要がある。例えば、図8(a)乃至図8(d)に示すように潜像画像(2c1)、潜像画像(2c2)、潜像画像(2c3)、潜像画像(2c4)の4つの潜像画像を出現させたい場合に、これらの4つの画像を合成して、基材(1a)に潜像画像(2c)を形成する必要があり、基材(1a)に設ける潜像画像(2c)を構成した穿孔(3c)は、基材(1a)を穿孔する穿孔(3a)に一部重なって規則的に配置する必要がある。基材(1a)を貫通しない穿孔(3c)が、図9に示すように穿孔(3a)に対してY1位置に規則的に配置(この場合、潜像画像2c1)された場合は、X1方向に傾けて透過光で観察することが必要であり、Y2位置に規則的に配置(この場合、潜像画像2c2)された場合は、X2方向に傾けて透過光で観察することが必要であり、Y3位置に規則的に配置(この場合、潜像画像2c3)された場合は、X3方向に傾けて透過光で観察することが必要であり、Y4位置に規則的に配置(この場合、潜像画像2c4)された場合は、X4方向に傾けて透過光で観察することが必要である。また、基材の表裏どちらの面からも上記記載の同一方向から観察可能である。
【0036】
よって、このような基材(1a)を貫通しない穿孔によって潜像画像(2c)を設けた真偽判別形成体(4b)は、図10(a)に示すように、図9に示した基材を貫通しない穿孔が形成されていない面からX1方向に傾けて透過光で観察する場合はY1に規則的に配置された潜像画像(2c1)(この場合は数字の2)が視認され、図10(b)に示すように、図9に示したX2方向に傾けて透過光で観察する場合はY2に規則的に配置された潜像画像(2c2)(この場合は数字の3)が視認され、図10(c)に示すように、図9に示したX3方向に傾けて透過光で観察する場合はY3に規則的に配置された潜像画像(2c3)(この場合は数字の4)が視認され、図10(d)に示すように、図9に示したX4方向に傾けて透過光で観察する場合はY4に規則的に配置された潜像画像(2c4)(この場合は数字の5)が視認される。つまり、透過光で異なる4方向から傾けて異なる4つの画像が視認できることとなる。また、基材の表裏どちらの面からも上記記載の同一方向から観察可能である。
【0037】
上記の真偽判別形成体(4b)は、4つの画像を出現されているが、言うまでもなく、2つ、3つの画像を出現させることもできる。また、潜像画像(2c1)、潜像画像(2c2)、潜像画像(2c3)、潜像画像(2c4)の4つの潜像画像は、穿孔(3a)に対して上下左右に規則的に配置されているが、斜め方向に規則的に配置させてもよく、この場合、上下左右に規則的に配置された穿孔と斜めに規則的に配置させて穿孔を組み合わせて8つの潜像画像を出現させることも可能である。また、このような複数の潜像画像を用いて、動画的にそれぞれの潜像画像の一部を異ならせ、真偽判別形成体を作製することによって、透過光で傾けて真偽判別形成体を回転させて観察することによって潜像画像が動画像のように動いて観察することができる。また、潜像画像(2c1)、潜像画像(2c2)、潜像画像(2c3)、潜像画像(2c4)の4つの潜像画像は、すべて異なっている画像を用いているが、同一の画像を用いても、同一の画像と異なった画像を組み合わせても良い。
【0038】
以上、真偽判別形成体(4a)、(4b)をまとめると、基材を貫通しない穿孔による潜像画像が、n個の異なった潜像画像を合成した穿孔によって構成され、n1の潜像画像を構成する穿孔が、基材を貫通する穿孔による画像を構成する穿孔に対して、一部重なるように規則性をもって配置され、n2、n3、n4…の潜像画像を構成する穿孔が、基材を貫通する穿孔による画像を構成する穿孔に対して、n1の潜像画像を設けた領域以外で、基材を貫通する穿孔による画像を構成する穿孔に、一部重なるように規則性をもって配置される必要がある。
【0039】
次に、基材に対して垂直方向から透過光で観察した場合に立体的な画像が視認できる場合を示す。基材を貫通する穿孔による画像は図1に示したものを用いる。基材に対して垂直方向から透過光で観察した場合に立体的な像が視認できるようにするためには、基材を貫通しない穿孔の配置に規則性を持たせる必要がある。図11に示すように、基材を貫通しない穿孔(3c)による一対の潜像画像(2c1、2c2)は、基材を貫通する穿孔(3a)と、一部重なるように、基材を貫通する穿孔(3a)に対して規則性をもって左右、上下等の対称に設ける必要がある。さらに、基材を貫通しない穿孔(3c)による一対の潜像画像(2c1、2c2)を配置する位置は、両眼視差を考慮した位置に配置する必要がある(図11)。
【0040】
基材を貫通しない穿孔(3c)による一対の潜像画像(2c1、2c2)を、基材を貫通する穿孔(3a)と、一部重なるように、基材を貫通する穿孔(3a)に対して対称に設けて作製した真偽判別形成体(4c)は、図12に示すように基材に対して垂直方向から透過光で観察した場合に、観察者の左眼には、基材を貫通する穿孔(3a)の右側に設けた、基材を貫通しない穿孔(3c)による潜像画像(2c1)が視認され、観察者の右眼には、基材を貫通する穿孔(3a)の左側に設けた、基材を貫通しない穿孔(3c)による潜像画像(2c2)が視認されることによって、基材を貫通しない穿孔による潜像画像が立体的に視認される。つまり、基材を貫通しない穿孔による一対の潜像画像(2c1、2c2)は、基材を貫通する穿孔による画像(2a)をパララックスバリアとする位置に配置する必要がある。
【0041】
本発明の穿孔はレーザ穿孔装置等で付与でき、大きさは50〜1000ミクロンが好ましい。穿孔の大きさは基材の厚みと表現したい画像の解像度や数と関係がある。当然、特定の領域に高い解像度の画像を表現する場合にはできるだけ小さな径の穿孔が必要であるが、数十ミクロン以下であると穿孔を作成する上で困難となる。また、大きな径の穿孔を用いる場合は、表現できる画像が粗いものとなってしまう。
【0042】
本発明の画像を形成する穿孔と潜像画像を形成する穿孔の重なる度合いは、潜像画像を形成する穿孔の直径の0%〜70%が好ましい。潜像画像を形成する穿孔の直径は、設ける潜像画像の数と関係があり、画像を形成する穿孔の直径の50%〜100%が好ましい。
【0043】
本発明に用いる基材は、特に限定されることはなく、紙葉類、フィルム、プラスティック等を利用することができる。また、基材の厚さについても特に限定されることはないが、0.1mmから1.0mm程度が好ましい。
【0044】
本発明の穿孔の形状は、特に限定されることはなく、円形、多角形及び特殊な形状の穿孔の少なくとも一つで形成する必要がある。多角形又は特殊な形状の穿孔を用いることによって、複製されにくくなるため偽造防止効果が向上する。
【0045】
本発明の画像を構成する穿孔及び潜像画像を構成する穿孔が、基材に対して直角及び特定の角度で斜めの形状の少なくとも一つで形成することができる。特定の角度で斜めに形成した場合、複製されにくくなるため偽造防止効果が向上する。特定の角度で斜めの角度を深めると潜像が視認される観察角度も多少深くなる。
【0046】
本発明の穿孔が、深さ方向に伴って、穿孔の直径が同一及び穿孔の直径が小さくなる形状の少なくとも一つで形成することによって、複製されにくくなるため偽造防止効果が向上する。
【0047】
本発明の潜像画像が、文字、数字、記号及び絵柄の少なくとも1つであることにより、透過光で傾けて観察した場合に真偽判別効果が向上する。
【0048】
本発明の基材を貫通しない穿孔により形成した穿孔群からなる潜像画像をカモフラージュするために基材を貫通しない穿孔により形成した穿孔群からなる潜像画像を形成した面に貫通しない穿孔を設けることによって、裏面から潜像画像が視認されてしまうことを防ぐことができる。カモフラージュの穿孔については図23に示す。
【0049】
本発明の穿孔の粗密、大きさ及び配置の少なくとも一つで潜像画像又は/及び画像を形成することによって潜像画像又は/及び画像に階調を付与することができる。
【0050】
以上の構成中の画像と潜像画像の配置関係を概念的に簡単に整理すると、図19に示す通りである。本発明の画像と潜像画像を形成する穿孔が基材に対して特定の角度で斜めに形成した場合の図を図20に示す。穿孔の角度以外は真偽判別形成体(4a)と同様な構成を示す構成を図20(a)に示す。穿孔の角度以外は真偽判別形成体(4b)と同様な構成を示す構成を図20(b)に示す。穿孔の角度以外は真偽判別形成体(4c)と同様な構成を示す構成を図20(c)に示す。図20(a)、図20(b)の効果は、真偽判別形成体(4a、4b)とは異なり、垂直方向から透過光で観察した場合に画像は観察できないが、傾けて観察した場合に画像が観察され、更に傾けると潜像画像が観察される。図20(c)の効果は真偽判別形成体(4c)とは異なり、垂直方向から透過光で観察した場合に画像は観察できないが、傾けて観察した場合に潜像画像が立体的に観察される。本発明の穿孔が、深さ方向に伴って、穿孔の径が小さくなる形成する場合の図を図21に示す。図21は、切頭円錐の一例を示す。また、本発明の画像と基材を潜像画像を形成する穿孔の大きさが同一の場合でも、穿孔の配置位置によっては基材を斜めから観察した場合に階調ある潜像画像を視認することができる。
【0051】
上記記載の真偽判別形成体(4a、4b、4c)は1枚の基材に形成されているが、本発明はこれに限定されることなく、次の構成によっても本発明の効果を奏することができる。図22(a)乃至(c)に示すように第1の基材(11a)と第2の基材(11b)を設ける2層構造にしても良い。この場合、画像および潜像画像は基材を貫通する穿孔を用いる。図22(a)は真偽判別形成体(4a)と同様な効果を示し、第1の基材(11a)に画像(2a)を構成する基材を貫通する穿孔(3a)を設け、第2の基材(11b)に潜像画像(2c)及び第1の基材(11a)に設けた画像(2a)と同一の画像(2a’)を構成する基材を貫通する穿孔(3c)を設けた構成である。図22(b)は真偽判別形成体(4b)と同様な効果を示し、第1の基材(11a)に画像(2a)を構成する基材を貫通する穿孔(3a)を設け、第2の基材(11b)に潜像画像(2c)及び第1の基材(11a)に設けた画像(2a)と同一の画像(2a’)を構成する基材を貫通する穿孔(3c)を設けた構成である。図22(c)は真偽判別形成体(4c)と同様な効果を示し、第1の基材(11a)に画像(2a)を構成する基材を貫通する穿孔(3a)を設け、第2の基材(11b)に潜像画像(2c)及び第1の基材(11a)に設けた画像(2a)と同一の画像(2a’)を構成する基材を貫通する穿孔(3c)を設けた構成である。第1の基材(11a)と第2の基材(11b)は接着剤等で接着されても良い。ただし、真偽判別形成体(4a、4b、4c)を2層構造で形成した場合、第1の基材を貫通する穿孔で構成された画像と第2の基材を貫通する穿孔で構成された画像が同一であり、且つ、第1の基材を貫通する穿孔で構成された画像と第2の基材を貫通する穿孔で構成された画像が重なるように、第1の基材と第2の基材が積層されている必要がある。また、穿孔の形状、大きさ、ピッチ、カモフラージュ等は真偽判別形成体(4a、4b、4c)と同様な要素を用いることができる。

【0054】
(実施例2)
厚さ約0.15mmの紙を1枚用意し、この紙に、直径0.1mmの穿孔を0.8mmの一定間隔で格子状に、レーザ加工機によって紙を貫通させて図柄(A)を施した(図15参照)。またこの紙に、直径0.1mmの穿孔を0.8mmの一定間隔で、レーザ加工機によって紙を貫通させることなく一定の深さで異なる4つの潜像図柄(B1)、潜像図柄(B2)、潜像図柄(B3)、潜像図柄(B4)が形成されている潜像図柄(B)を施した(図15参照)。紙に施した図柄(A)の穿孔と、紙に施した潜像図柄(B)を形成する穿孔が、図柄(A)の穿孔を基準として、潜像図柄(B1)を形成している穿孔が右側(上側を0度とした場合、90度)に規則的に配置し、潜像図柄(B2)を形成している穿孔が左側(上側を0度とした場合、270度)に規則的に配置し、潜像図柄(B3)を形成している穿孔が下側(上側を0度とした場合、180度)に規則的に配置し、潜像図柄(B4)を形成している穿孔が上側(上側を0度とした場合、0度)に規則的に配置して真偽判別形成体(C2)を作成した(図15参照)。この真偽判別形成体(C2)を反射光で観察した場合には、図柄(A)のみが視認され、透過光で図15に示す基材を貫通しない穿孔が形成されていない面からX1方向から観察した場合には、図16(a)に示すように図柄(A)内に潜像図柄(B1)が視認でき、透過光で図15に示すX2方向から観察した場合には、図16(b)に示すように図柄(A)内に潜像図柄(B2)が視認でき、透過光で図15に示すX3方向から観察した場合には、図16(c)に示すように図柄(A)内に潜像図柄(B3)が視認でき、透過光で図15に示すX4方向から観察した場合には、図16(d)に示すように図柄(A)内に潜像図柄(B4)が視認できた。また、基材の表裏どちらの面からも上記記載の同一方向から観察できた。
【0055】
(実施例3)
厚さ約0.3mmの紙を1枚用意し、この紙に、直径0.08mmの穿孔を0.8mmの一定間隔で格子状にレーザ加工機によって紙を貫通させて図柄(A)を施した(図17参照)。またこの紙に、直径0.08mmの穿孔を0.8mmの一定間隔で、レーザ加工機によって紙を貫通させることなく深さ約0.15mmで一対の潜像図柄(B1、B2)を施した(図17参照)。このとき、紙に施した図柄(A)の穿孔と、紙に施した一対の潜像図柄(B1、B2)を形成する穿孔が、図柄(A)の穿孔の中心から左側および右側0.04mmずらして規則的に配置し、真偽判別形成体(C3)を作成した(図17参照)。この真偽判別形成体(C3)を反射光で観察した場合には、図柄(A)のみが視認され、図18に示すように、基材に対して垂直方向から透過光で、約300mm離れた距離から観察した場合には、左眼と右眼にそれぞれ潜像図柄(B1)と潜像図柄(B2)が見えることから、図柄(A)内に立体的な潜像画像が視認することができた。
【0056】
以上、本発明の実施例に基づいて説明したが、本発明はこの実施例に限定されるものではなく、特許請求の範囲記載における技術的思想の範囲内であれば、その他のいろいろな実施の形態が考えられる。
【0057】
【発明の効果】
基材に貫通する穿孔群からなる画像と、これらの穿孔と基材を貫通しない穿孔群からなる潜像画像を形成し、画像を形成する基材を貫通する穿孔位置と、潜像画像を形成する基材を貫通しない穿孔位置を対応して配置することによって、透過光で観察した場合に明瞭な潜像画像の出現、多方向から異なる潜像画像の出現、鮮明な立体的な潜像画像の出現がされるため、真偽判別効果の高い、改ざん、複製防止効果のある真偽判別形成体と成り得、銀行券、パスポート、有価証券、カード、印紙類等の偽造、複写、改ざんを防止する必要性のある貴重印刷物に適用することができる。
【0058】
また、第1の基材に貫通する穿孔群からなる画像と、これらの穿孔と第2の基材を貫通する穿孔群からなる潜像画像を形成し、画像を形成する第1の基材を貫通する穿孔位置と、潜像画像を形成する第2の基材を貫通する穿孔位置を対応して配置して、第1の基材と第2の基材を積層することによって、透過光で観察した場合に明瞭な潜像画像の出現、多方向から異なる潜像画像の出現、鮮明な立体的な潜像画像の出現がされるため、真偽判別効果の高い、改ざん、複製防止効果のある真偽判別形成体と成り得、銀行券、パスポート、有価証券、カード、印紙類等の偽造、複写、改ざんを防止する必要性のある貴重印刷物に適用することができる。
【0059】
デザイン上、異なる複数の観察方向により第2の画像を出現させることが可能であり、真偽判別装置等を用いることなく誰でもその場で真偽判別することができる。また、本デバイスを偽造、改竄しようとした場合、基材を貫通する穿孔と基材を貫通しない穿孔の位置関係、又は、第1の基材を貫通する穿孔と第2の基材を貫通する穿孔の位置関係を忠実に再現する必要があり、微細な穿孔自体の再現のみならず、それらの配置までも再現することは非常に困難となる。
【0060】
本発明の真偽判別形成体はレーザを垂直に照射し、且つ、基材を水平方向に自動搬送するような大量生産ラインを構成する装置でも作製でき、基材に斜め穿孔を形成しなくとも潜像画像を形成できるため、複雑な加工機を用いることなく作製できる。

BACKGROUND OF THE INVENTION
The present invention relates to a true / false discrimination forming body applied to valuable printed matter that needs to be prevented from forgery and tampering such as banknotes, passports, securities, cards, and stamps.
[0002]
[Prior art]
Due to the nature of precious printed matter such as banknotes, passports, securities, cards, and stamps, they are required to be difficult to forge or alter. As a preventive measure, it is known to form numbers or the like on a substrate of these valuable printed materials by a plurality of perforations. There is also known a technique for performing authenticity determination by allowing a latent image to be visually recognized by tilting and observing a substrate having a plurality of perforations.
[0003]
The former is used for Swiss banknotes, and the numbers are expressed by perforations. In addition, the hole diameter is characterized in that the pattern formed by the naked eye cannot be seen in the reflective state, and the safety mark is composed of a plurality of holes that form a pattern on the document surface that is visible in the transparent state. A safekeeping document provided with a safety mark for preventing this is disclosed (for example, see Patent Document 1).

DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the authenticity determination forming body according to the present invention will be described with reference to the drawings. The true / false discrimination formed body of the present invention is characterized by an image comprising a group of perforations formed by perforations penetrating through a two-dimensionally arranged substrate formed on the substrate, and a two-dimensionally arranged base formed on the substrate. A latent image composed of a perforation group formed by perforation not penetrating the material is provided, and each perforation position of the perforation group not penetrating the base material forming the latent image is determined by the perforation group penetrating the base material forming the image. Arrangement corresponding to each perforation position makes it possible to observe a latent image formed by perforation that does not penetrate the substrate when observed from a specific observation direction with transmitted light. In addition, an image including a group of perforations formed by perforations penetrating the first base material formed on the first base material and the second base material formed on the second base material. A latent image formed by a perforation group formed by perforation penetrating through the second base material and an image identical to the image formed on the first base material formed by perforation group formed by the perforation penetrating the second base material are provided. The individual perforation positions of the perforation group penetrating the latent image and the second substrate forming the same image correspond to the individual perforation positions of the perforation group penetrating the first substrate forming the image. Thus, the latent image formed in the second description can be observed when observed from a specific observation direction with transmitted light.
[0031]
FIG. 1 shows a view in which an image (2a) is formed on a substrate (1a) by perforation (3a) and a sectional view taken along line XX ′. As shown in FIG. 1, the perforations (3a) need to penetrate the substrate. FIG. 2 shows a view in which only the latent image (2c) is formed on the substrate (1a) by perforation (3c) and a cross-sectional view taken along line XX ′. As shown in FIG. 2, the perforations (3c) need to be formed at a certain depth or a predetermined depth without penetrating the substrate. Authenticity discrimination formed body (4a) on which image (2a) formed by perforation (3a) shown in FIGS. 1 and 2 and latent image (2c) formed by perforation (3c) are applied, and its XX 'A cross-sectional view is shown in FIG. As shown in FIG. 3, the perforations (3c) that do not penetrate through the base material (1a) need to be regularly arranged so as to partially overlap the perforations (3a) that penetrate through the base material (1a). In this case, the perforations (3c) that do not penetrate the substrate (1a) are regularly arranged on the left side with respect to the perforations (3a) that penetrate the substrate (1a). Or what is necessary is just to arrange | position regularly so that it may partially overlap with the lower part etc., ie, the peripheral region of the piercing | piercing (3a) which penetrates a base material (1a).
[0032]
FIG. 5A shows a case where the authenticity determination formed body (4a) is observed with reflected light, and FIG. 5B shows a case where the authenticity determination formed body (4a) is transmitted with light from a direction perpendicular to the substrate. The figure when observed is shown. As shown in FIG. 5A, the perforations (3c) that do not penetrate the base material (1a) forming the latent image (2c) are the same color as the base material. An observer will recognize only the image (2a) by the perforation which penetrates a base material (1a). Further, as shown in FIG. 5B, when the authenticity determination formed body (4a) is observed with transmitted light from a direction perpendicular to the base material, the observer perforates through the base material (1a). In order to feel strongly the light transmitted through (3a), only the image (2a) by the perforations (3a) penetrating the substrate (1a) is recognized. In either case, the latent image (2c) cannot be visually recognized.
[0033]
FIG. 6 shows a view when the authenticity determination formed body (4a) is observed with transmitted light from the X direction shown in FIG. As shown in FIG. 6, the latent image (2c) by the perforation (3c) not penetrating the base material (1a) is clearly visible in the image (2a) by the perforation (3a) penetrating the base material (1a). (In this case the number 1). This is because the perforations (3c) constituting the latent image (2c) provided on the substrate (1a) partially overlap the perforations (3a) constituting the image (2a) provided on the substrate (1a). 4 is transmitted from a region where the perforations (3a) and the perforations (3c) are visually recognized by observing from the direction in which the transmitted light can be observed as shown in FIG. Since the amount of transmitted light is hardly recognized from a region where the amount of light is strong and the perforation (3a) and the perforation (3c) do not overlap, the difference in contrast causes a latent image in the image (2a) as shown in FIG. The image (2c) can be visually recognized.
[0034]
As to the observable direction, as shown in FIG. 7, the perforation (3c) that does not penetrate the base material (1a) constituting the latent image (2c) and the base material (1a) that constitutes the image (2a) are penetrated. Depends on the arrangement rule with the perforation (3a) to be performed. That is, as shown in the XX ′ sectional view of FIG. 7, the base material constituting the latent image (2c) with respect to the perforations (3a) penetrating the base material (1a) constituting the image (2a). When the perforations (3c) that do not penetrate (1a) are regularly arranged on the Y1 side, it is necessary to incline in the X1 direction and observe with transmitted light, and when they are regularly arranged on the Y2 side, It is necessary to incline in the X2 direction and observe with transmitted light. Moreover, it can be observed from the same direction as described above from either the front or back surface of the substrate.
[0035]
Next, FIG. 9 shows a case where the authenticity determination formed body (4b) in which different latent image images can be seen from four different directions with transmitted light is viewed from the surface where the perforations that do not penetrate the substrate are formed. As the substrate, a substrate in which the image shown in FIG. 1 is formed by perforation is used. In order to be able to visually recognize different images from four different directions with transmitted light, it is necessary to provide regularity to the perforations that do not penetrate the substrate and the perforations that penetrate the substrate. For example, as shown in FIGS. 8A to 8D, four latent image images, that is, a latent image (2c1), a latent image (2c2), a latent image (2c3), and a latent image (2c4). When these four images are desired to appear, it is necessary to form a latent image (2c) on the substrate (1a), and the latent image (2c) provided on the substrate (1a) The configured perforations (3c) need to be regularly arranged so as to partially overlap the perforations (3a) for perforating the substrate (1a). When the perforations (3c) that do not penetrate the substrate (1a) are regularly arranged at the Y1 position with respect to the perforations (3a) as shown in FIG. 9 (in this case, the latent image 2c1), the X1 direction It is necessary to observe with transmitted light tilted in the direction of X2, and when arranged regularly at the Y2 position (in this case, the latent image 2c2), it is necessary to observe with transmitted light tilted in the X2 direction. , Regularly arranged at the Y3 position (in this case, the latent image 2c3), it is necessary to incline in the X3 direction and observe with transmitted light, and regularly arranged at the Y4 position (in this case, the latent image 2c3). In the case of the image 2c4), it is necessary to incline in the X4 direction and observe with transmitted light. Moreover, it can be observed from the same direction as described above from either the front or back surface of the substrate.
[0036]
Therefore, the authenticity determination formed body (4b) provided with the latent image (2c) by the perforation that does not penetrate the base material (1a) has the base shown in FIG. In the case of observing with transmitted light tilted in the X1 direction from a surface where no perforations that do not penetrate the material are formed, a latent image (2c1) (in this case, the number 2) regularly arranged in Y1 is visually recognized, As shown in FIG. 10B, when observing with transmitted light tilted in the X2 direction shown in FIG. 9, the latent image (2c2) (in this case, the number 3) regularly arranged in Y2 is obtained. As shown in FIG. 10 (c), the latent image (2c3) regularly arranged in Y3 (in this case, a numerical number) when tilted in the X3 direction shown in FIG. 4) is visually recognized, and as shown in FIG. 10 (d), it is tilted in the X4 direction shown in FIG. Latent images which are regularly arranged in Y4 (2c4) (5 in this case is a number) it is visible when the Judging. That is, four different images can be visually recognized by tilting from four different directions with transmitted light. Moreover, it can be observed from the same direction as described above from either the front or back surface of the substrate.
[0037]
In the authenticity discrimination formation body (4b), four images have appeared. Needless to say, two or three images can also appear. The four latent image images of the latent image (2c1), the latent image (2c2), the latent image (2c3), and the latent image (2c4) are regularly arranged vertically and horizontally with respect to the perforation (3a). However, it may be arranged regularly in an oblique direction. In this case, eight latent image images are formed by combining the holes regularly arranged vertically and horizontally and the holes regularly arranged obliquely. It is also possible to make it appear. Further, by using such a plurality of latent image images, a part of each latent image is differentiated in a moving image to produce a true / false discriminating body, which is tilted by transmitted light, and an authenticity discriminating body. By rotating and observing, the latent image can move and be observed like a moving image. The four latent image images of the latent image (2c1), the latent image (2c2), the latent image (2c3), and the latent image (2c4) are all different images. Even if an image is used, a different image may be combined with the same image.
[0038]
As described above, when the authenticity determination formed bodies (4a) and (4b) are put together, the latent image formed by the perforations that do not penetrate the base material is formed by the perforations obtained by synthesizing n different latent image images. The perforations constituting the image are arranged with regularity so as to partially overlap the perforations constituting the image by the perforations penetrating the substrate, and the perforations constituting the latent image of n2, n3, n4. With respect to the perforations constituting the image by the perforation penetrating the base material, with regularity so as to partially overlap the perforations constituting the image by the perforation penetrating the base material, except for the region where the n1 latent image is provided. Need to be deployed.
[0039]
Next, a case where a three-dimensional image can be visually recognized when observed with transmitted light from a direction perpendicular to the substrate will be described. The image shown in FIG. 1 is used as an image by drilling through the substrate. In order to make a three-dimensional image visible when observed with transmitted light from a direction perpendicular to the substrate, it is necessary to provide regularity in the arrangement of the perforations that do not penetrate the substrate. As shown in FIG. 11, the pair of latent image images (2c1, 2c2) by the perforations (3c) that do not penetrate the substrate penetrates the substrate so as to partially overlap the perforations (3a) that penetrate the substrate. It is necessary to provide regularity symmetrically with respect to the perforation (3a) to be performed, such as left and right and up and down. Furthermore, the position where the pair of latent image (2c1, 2c2) by the perforation (3c) that does not penetrate the base material needs to be arranged at a position that takes binocular parallax into consideration (FIG. 11).
[0040]
A pair of latent image (2c1, 2c2) by a perforation (3c) that does not penetrate the base material is compared with a perforation (3a) that penetrates the base material so as to partially overlap the perforation (3a) that penetrates the base material. As shown in FIG. 12, the true / false discrimination formed body (4c) prepared symmetrically is observed with the transmitted light from the direction perpendicular to the base material. The latent image (2c1) provided by the perforation (3c) provided on the right side of the perforation (3a) that does not penetrate the base material is visually recognized, and the right eye of the observer has the perforation (3a) that penetrates the base material. The latent image (2c2) provided on the left side by the perforation (3c) that does not penetrate the base material is visually recognized, so that the latent image by the perforation that does not penetrate the base material is viewed three-dimensionally. That is, the pair of latent image images (2c1, 2c2) formed by the perforations that do not penetrate the base material needs to be arranged at positions where the images (2a) formed by the perforations that penetrate the base material are used as the parallax barrier.
[0041]
The perforation of the present invention can be applied with a laser perforation apparatus or the like, and the size is preferably 50 to 1000 microns. The size of the perforation is related to the thickness of the substrate and the resolution and number of images to be expressed. Naturally, when a high-resolution image is expressed in a specific area, a hole having a diameter as small as possible is necessary. However, if it is several tens of microns or less, it is difficult to create the hole. In addition, when a large-diameter perforation is used, an image that can be expressed becomes rough.
[0042]
The overlapping degree of the perforations that form the image of the present invention and the perforations that form the latent image is preferably 0% to 70% of the diameter of the perforations that form the latent image. The diameter of the perforations that form the latent image is related to the number of latent images that are provided, and is preferably 50% to 100% of the diameter of the perforations that form the image.
[0043]
The substrate used in the present invention is not particularly limited, and paper sheets, films, plastics and the like can be used. The thickness of the substrate is not particularly limited, but is preferably about 0.1 mm to 1.0 mm.
[0044]
The shape of the perforation of the present invention is not particularly limited, and it is necessary to form at least one of a circular shape, a polygonal shape, and a special shape. By using polygonal or specially shaped perforations, the anti-counterfeiting effect is improved because it becomes difficult to be duplicated.
[0045]
The perforation constituting the image of the present invention and the perforation constituting the latent image can be formed in at least one of a right angle and a specific angle with respect to the substrate. When it is formed obliquely at a specific angle, it becomes difficult to replicate, so the forgery prevention effect is improved.
