Description

【0001】
【発明の属する技術分野】
本発明は、肉眼では見えない図柄が所定の器具を用いることにより見えるようになる被観察体に関するものである。本発明に係る被観察体は、限定はされないが、例えば、玩具、販売促進用品、教材等に適用できるほか、広告手段、真偽判定手段として用いることもできる。
【0002】
【従来の技術】
教育玩具等に適用して好適な装飾体として、万線フィルムと言われるフィルムを重ねると絵(隠し図柄)が出てくる形式のものが知られている(例えば、非特許文献1参照)。
【0003】
【非特許文献1】
共同印刷株式会社編「特殊印刷はやわかり図鑑」
(社)日本印刷技術協会 2001年10月発行
【0004】
【発明が解決しようとする課題】
前記従来のものにおいては、確かに、前記万線フィルムを用いることにより、前記隠し図柄が見やすくはなる。しかし、前記万線フィルムを用いなくても、前記隠し図柄を視認することは可能であり、意図された意外性や面白さ等が十分に発揮されているとは言えなかった。
【0005】
本発明は、このような事情に鑑みてなされたもので、隠し図柄の発現に意外性のある、被観察体を提供しようとするものである。
【0006】
【課題を解決するための手段】
前記課題を解決するため、本発明の一実施の形態に係る被観察体は、肉眼では視認困難な同一の微細図柄が面上の少なくとも一部に二次元的に多数配列されていて、レンズが二次元的に多数配列されている視認器具によって前記微細図柄と相似する拡大図柄が視認可能となるものである(請求項1)。
【0007】
前記被観察体においては、肉眼では視認困難な同一の微細図柄が、前記面上に二次元的に多数配列されている。観察者が肉眼で見た場合には、個々の微細図柄を認識することは勿論、前記被観察体の前記面上に、前記微細図柄が二次元的に配列されていることさえも気づかれない。一方、前記視認器具を用いて前記被観察体を見た場合には、前記レンズの配列方向と前記微細図柄の配列方向とが所定の関係となったときに、前記微細図柄と相似する拡大図柄が観察者の目で認識可能となる。よって、前記拡大図柄の発現に十分な意外性がある。
【0008】
前記被観察体の具体的な適用範囲は広く、例えば、玩具、販売促進用品、教材等のほか、広告手段や真偽判定手段としても用いることができる。広告手段として用いる場合には、例えば、前記被観察体に対して、前記視認器具を、変位自在に配設しておく。このようにすれば、前記微細図柄が見えたり消えたりを繰り返すので、大衆の注目を引き易く、大きな広告効果が得られる。また、真偽判定手段として用いる場合には、前記微細図柄を、あらかじめ真正品に二次元的に多数配列させておく。前記視認器具を用いて拡大図柄の有無をチェックすることにより、被検査物が真正品であるかどうかを容易に判別することができる。
【0009】
本発明において、個々のレンズの大きさは、必ずしも同じでなくとも良い。同様に、個々の微細図柄の大きさも、必ずしも同じでなくても良い。さらに、レンズと微細図柄の大小関係は不問である。
【0010】
また、本発明において、前記レンズの二次元的配列態様と、前記微細図柄の二次元的配列態様は、必ずしも互いに同一である必要はなく、前記レンズシートとの組み合わせで前記拡大図柄が表出可能なものであれば、互いに異なっていても良い。
【0011】
さらに、本発明において、「微細図柄」とは、絵や図形だけでなく、文字も含むものとする。
【0012】
好適な実施の一形態として、前記面上に、肉眼で視認可能な図柄を備え、該肉眼可視図柄を有する領域と前記微細図柄を有する領域の双方が、いずれも、イエロー、マゼンタ、シアン、ブラックの四色のうちの少なくとも一つの色版を用いて形成され、前記肉眼可視図柄を有する領域と前記微細図柄を有する領域を形成するための互いに異なる線数を合体させて作った版を印刷に使用して形成したものとすることもできる(請求項2)。
【0013】
このようにすれば、前記視認器具を用いないときには、前記肉眼可視図柄のみが見え、前記視認器具を用いると、前記肉眼視認図柄に加えて、前記拡大図柄も見える。よって、芸術性が向上するとともに、面白みも増大して、好適である。加えて、前記肉眼可視図柄を有する領域と前記微細図柄を有する領域を形成するための互いに異なる線数を合体させて作った版を印刷して作るので、低コストで提供することができる。
【0014】
好適な実施の一形態として、前記微細図柄が、二次元的に多数配列された第一の微細図柄と第二の微細図柄とからなり、前記第一の微細図柄と前記第二の微細図柄が、互いに重なり合うように配置されているものとすることもできる(請求項3)。このようにすれば、前記視認器具なしでの前記微細図柄の認識可能性は全く無くなる。それは、前記第一又は第二のいずれか一方の微細図柄だけでも、小さすぎて肉眼では視認困難であるのに、それに他方の微細図柄が重なり合うように配置され、両者が交錯した状態となっているからである。よって、前記拡大図柄発現の意外性が一層向上する。
【0015】
前記構成は、前記視認器具なしでの前記微細図柄の認識可能性をほとんどゼロにせしめることから、前記被観察体を、偽造品検査手段等の真偽判定手段として用いる場合に、特に有効である。
【0016】
好適な実施の一形態として、前記第一の微細図柄が、前記レンズの配列ピッチとは異なるピッチで配列され、前記第二の微細図柄が、前記レンズの配列ピッチと同一のピッチで配列され、さらに、前記第一の微細図柄の配列方向と前記第二の微細図柄の配列方向とが互いに同一とされたものとすることもできる(請求項4)。
【0017】
この場合、前記視認器具を用いて前記被観察体を見たときには、前記第一の微細図柄の拡大図柄は視認できるが、その時には、前記第二の微細図柄の拡大図柄は全く見えない。
【0018】
好適な実施の一形態として、前記第一の微細図柄の配列方向と前記第二の微細図柄の配列方向とが互いに異なっていて、前記第一の微細図柄が、前記視認器具を前記被観察体に対して第一の角度で組み合わせた時に視認可能となり、前記第二の微細図柄が、前記視認器具を前記第一の角度とは異なる第二の角度で前記被観察体に対して組み合わせた時に視認可能となるものとすることもできる(請求項5)。
【0019】
この場合、前記被観察体上で前記視認器具を回転させて、前記被観察体に対する前記視認器具の組み合わせ角度を変えていくと、前記視認器具の配列方向と一致した配列の微細図柄のみが、拡大図柄として視認できる。よって、異なる図柄を探す楽しみが増す。
【0020】
好適な実施の一形態として、前記第一の微細図柄が、前記レンズの配列ピッチより小さいピッチで配列され、前記第二の微細図柄が、前記レンズの配列ピッチより大きいピッチで配列されたものとすることもできる(請求項6)。この場合、前記視認器具で前記被観察体を見ると、前記第一の微細図柄の拡大図柄は引っ込んで見える一方、前記第二の微細図柄の拡大図柄は飛び出して見えるので、立体感が十分に楽しめる。
【0021】
さらに、前記第一の微細図柄の配列方向と、前記第二の微細図柄の配列方向とを、互いに同一とすることもできる(請求項7)。このようにすれば、前記第一の微細図柄の拡大図柄と前記第二の微細図柄の拡大図柄の双方が、一方が引っ込み他方が飛び出した状態で同時に観察者の目に入るため、両者のコントラストにより、立体感がより強調される利点がある。
【0022】
【発明の実施の形態】
以下、添付図面を参照して、本発明の好適な一実施の形態について説明する。
【0023】
図1は、本実施の形態に係る被観察体としての図柄シート(図柄カード)の構成及び使用方法を示す平面図であり、(a)は、図柄シート自体の平面図、(b)は、前記図柄シートと組み合わせて使用する隠し図柄視認器具としてのレンズシートの平面図、(c)は、前記図柄シートに前記レンズシートを重ね合わせた状態を示す平面図である。図2は、前記レンズシートの一部拡大断面図である。
【0024】
図1(a)に示すように、本実施の形態では、本発明に係る被観察体を、肉眼では見えない隠し図柄を有する図柄シート(図柄カード)10として具体化してある。この図柄シート10は、肉眼では視認困難な同一の微細図柄11(図1の例では、「あ」の文字)が、面上の少なくとも一部に、二次元的に多数配列されたものである。そして、微細なレンズ2が二次元的に多数配列されている視認器具としてのレンズシート3(図1(b)参照)を用いることによって、図1(c)に示すように、前記微細図柄11と相似する拡大図柄11aが視認可能となる。
【0025】
図1(a)において、被観察体としての図柄シート10の表面には、肉眼で視認可能な肉眼可視図柄4(一例として、バラの花)と、肉眼では視認困難な微細図柄11が、印刷等の適宜の方法で形成されている。微細図柄11は、絵、図形、文字のいずれでも良いが、図1の例では、肉眼では見えないほどきわめて小さい「あ」の文字を、縦横に二次元的に規則的に配列したものとされている。視認器具としてのレンズシート3を用いないで図柄シート10を見ると、観察者には、肉眼可視図柄4のみが見え、微細図柄は、一つ一つが小さく、しかもきわめて小さなピッチで二次元的に配列されているので、微細図柄11自体は勿論、それが図柄シート10の表面にあることさえも、観察者には認識できない。
【0026】
一方、図1(c)に示すように、図柄シート10にレンズシート3を重ねて上から観察すると、レンズシート3の作用によって、微細図柄11と相似する拡大図柄11aが視認可能となる。レンズシート10は透過性を有するので、図柄シート10上に重ねても、肉眼可視図柄4の見え方は変わらない。
【0027】
前記レンズシート3は、図1(b)及び図2に示すように、一例として、透明なシート状基材5の表面に、多数のレンズ、具体的にはドーム状又は凸状のレンズ2を、縦横に二次元的に規則的に配列したものとされている。個々のレンズ2はきわめて小さいものであるが、その厚みTLが大きければ大きいほど、前記微細図柄11の拡大視認性が向上する。凸レンズ2の配列ピッチP(L)も、隣接する凸レンズ同士が干渉し合わない範囲で、小さいことが望ましい。限定はされないが、一例として数値を与えるとすれば、例えば、凸レンズの厚みTLを60μm、平面視での大きさ(直径)Dを400μm、縦横の配列ピッチP(L)を500μmとすることができる。この場合、個々の凸レンズ2を網点と考えれば、凸レンズ2は、50.8線(/インチ)で配列又は形成されていると言える。前記シート状基材5の厚みTBは、例えば、0.8〜1.2mmとする。
【0028】
なお、前記レンズシート3は、それ自体公知のものであり、例えば、プラスチック製等の透明なシート状基材5の表面に、スクリーン印刷の手法を用いて、紫外線硬化樹脂インク等の透明材料をドーム状に付着せしめることにより、前記凸レンズ2を形成することができる。
【0029】
図1の例では、前記微細図柄11の配列ピッチPが、前記凸レンズ2の配列ピッチP(L)とは異なる大きさとされている。限定はされないが、具体的には、個々の微細図柄11を網点と考えると、前記レンズシート3の凸レンズ2の線数を50.8線とした場合、前記微細図柄11は、前記凸レンズ2の線数より小さい、例えば、44〜49線(/インチ)、又は、前記凸レンズの線数より大きい、例えば、52〜55線(/インチ)で、配列又は形成することができる。なお、線数が大きいことは、二次元的配列ピッチが小さいことと同義であり、線数が小さいことは、二次元配列ピッチが大きいことと同義である。
【0030】
一般に、レンズシートを用いて微細図柄を見る場合、レンズシートにおける凸レンズの配列ピッチと、図柄シートにおける微細図柄の配列ピッチと、の間の大小関係がどのようなものとなっているかにより、微細図柄の見え方が変わってくる。本発明の発明者等が、様々な態様の実物を作成して試験した結果、次の事実が確認できた。
【0031】
(イ)微細図柄の配列ピッチが、凸レンズの配列ピッチより大きい場合には、凸レンズの配列方向と微細図柄の配列方向とが互いに一致するように両者を重ね合わせると、微細図柄の拡大図柄は、飛び出して見える。
【0032】
(ロ)微細図柄の配列ピッチが、凸レンズの配列ピッチより小さい場合には、凸レンズの配列方向と微細図柄の配列方向とが互いに一致するように両者を重ね合わせると、微細図柄の拡大図柄は、引っ込んで見える。
【0033】
(ハ)微細図柄の配列ピッチが、凸レンズの配列ピッチと同一である場合には、凸レンズの配列方向と微細図柄の配列方向とが互いに一致するように両者を重ね合わせると、微細図柄の拡大図柄は発現しない。
【0034】
なお、本発明の発明者等の実験によれば、図柄シートに付された微細図柄をレンズシートで拡大図柄として視認し得るための条件として、レンズシートの個々のレンズの大きさは、必ずしも厳密に同じでなくとも良い。また、個々のレンズの平面形状は円形には限定されず、四角形や六角形等の他の形状であっても良い。同様に、個々の微細図柄の大きさも、必ずしも厳密に同じでなくても良い。さらに、個々のレンズと個々の微細図柄の大小関係も不問である。さらにまた、レンズ及び微細図柄の二次元的配列ピッチは、互いに直交する第一の方向(例えば縦方向)と第二の方向(例えば横方向)との間で、互いに同一とするのが普通であるが、必ずしも互いに同一でなくても良い。要するに、本発明においては、面上における肉眼では見えないほど小さな実質的に同一の微細図柄の集合を、面上における微細レンズの集合を通して見たときに、前記微細図柄と相似する拡大図柄が観察者の目に見えるものであれば良い。
【0035】
前記図柄シート10は、限定はされないが、例えば、次のようにして作成することができる。まず、前記肉眼可視図柄4を有する領域に対応する版を、イエロー、マゼンタ、シアン、ブラックの四色のうちの少なくとも一つの色版を用いて形成する。前記肉眼可視図柄4を形成する線数に限定はないが、印刷後、肉眼で見たときにその図柄が鮮明に美しく見える線数、例えば、175線(/インチ)等で作成することができる。
【0036】
前記微細図柄11を有する領域に対応する版も、イエロー、マゼンタ、シアン、ブラックの四色のうちの少なくとも一つの色版を用いて形成する。例えば、前記微細図柄を黒色で表示したい場合には、ブラックのフィルムに前記微細図柄を黒で表示すれば良い。一方、前記微細図柄11を地色で表示したい場合には、使用する色のフィルムにおいて、前記微細図柄11に対応する形状を抜けば良い。また、前記微細図柄11を他の色彩で表示したい場合には、その色彩を得るのに必要な色のフィルムに、前記微細図柄11を表示すれば良い。
【0037】
次いで、前記肉眼可視図柄4を有する領域を形成するための線数と、前記微細図柄11を有する領域を形成するための線数の、互いに異なる線数を合体させた版を作り、それを、例えば、オフセット印刷機にかけて、図柄シートを構成するための基材上に印刷する。このような作成方法によれば、互いに異なる線数を有する微細図柄11部分と肉眼可視図柄4部分とが、一度の印刷で基材上に同時に印刷されるので、前記図柄シート10を低コストで提供することができる。
【0038】
前記図柄シート10により、隠し図柄発現の意外性や多様性を楽しむことができるので、前記図柄シート10は、おもちゃ、販売促進用品、教材等として用いることができる。しかし、本発明の適用範囲は、これらに限定されるものではなく、広告手段や偽造品検査手段(真偽判定手段)等として適用することもできる。
【0039】
広告手段として用いる場合には、例えば、被観察体を大きく形成し、それに対して視認器具が重なったり外れたりを繰り返すように自動化しておく。このようにすれば、広告を見るものにとって、微細図柄が拡大図柄として見えたり消えたりするので、観者の興味や注目を引き易く、大きな広告効果が得られる。
【0040】
また、偽造品検査手段として用いる場合には、微細図柄を、あらかじめ真正品に二次元的に多数配列させておく。視認器具を用いて拡大図柄発現の有無をチェックすることにより、被検査物が真正品であるかどうかを容易且つ確実に判別することができる。
【0041】
次に、図3〜図5を参照して、本発明の他の実施の形態について説明する。
【0042】
図3〜図5は、いずれも、本発明の他の実施の形態に係る図柄シート及びその使用方法を示す平面図である。以下、これらの図柄シートを見るためのレンズシートは、図1(b)及び図2を参照して説明した前記のものと同じものとする。
【0043】
図3〜図5に示す三つの図柄シート30,40,50には、一つの共通点がある。すなわち、これらの図柄シート30,40,50の表面には、それぞれの図の(a)に拡大状態で示されているように、肉眼では視認困難な同一の第一の微細図柄31,41,51が二次元的に多数配列されるとともに、肉眼では視認困難な同一の第二の微細図柄32,42,52も、二次元的に多数配列されている。しかも、前記第一の微細図柄31,41,51と前記第二の微細図柄32,42,52は、個々のものが互いに重なり合うように配置されている。このため、前記レンズシート3なしでの前記微細図柄の認識可能性は全く無くなる。すなわち、前記第一又は第二のいずれか一方の微細図柄だけでも、小さすぎて、それがあることさえも肉眼では視認困難であるのに、それに他方の微細図柄が重なり合うように配置され、両者が交錯した状態になっているからである。よって、図柄シート30,40,50にレンズシート3を重ねて見た時の、図柄発現の意外性が一層向上し、玩具や販売促進用品としての使用に適している。
【0044】
また、図3〜図5に共通の前記構成は、本発明に係る被観察体を 偽造品検査手段等の真偽判定手段として用いる場合にも、好適である。すなわち、真正品には、あらかじめ、第一の微細図柄と第二の微細図柄を、既に述べた前記条件を満たす態様で付しておく。第一の微細図柄と第二の微細図柄は、それぞれが肉眼では見えないほど微小なものである上に、それらが互いに重なり合うように配置されているから、偽造品製造者にとって、レンズシートなしで、真正品における微細図柄の存在及びその具体的形状を見破ることは、ほとんど不可能である。よって、真正品を真似た偽造品には、微細図柄は付し得ないことになる。被検査物が真正品であれば、検査者が前記レンズシートを用いて見ることにより、第一の微細図柄の拡大図柄を確認することができるが、被検査物が偽造品である場合には、何の図柄も発現しない。
【0045】
なお、図3〜図5の例では、いずれも、微細図柄の種類を第一及び第二の二つとしているが、三つ以上としてもよいことは言うまでもない。
【0046】
次に、図3〜図5の図柄シートのそれぞれに特有な構成について説明する。
【0047】
図3(a)の図柄シート30においては、第一の微細図柄31として、数字の「2」が、前記凸レンズ2の配列ピッチP(L)とは異なるピッチP1で二次元的に配列されている。加えて、第二の微細図柄として、数字の「6」が、前記凸レンズ2の配列ピッチP(L)と同一のピッチP2で二次元的に配列されている。さらに、前記第一の微細図柄31の配列方向と前記第二の微細図柄の配列方向とが、互いに同一とされている。
【0048】
図3(b)に示すように、図3(a)の図柄シート30と前記レンズシート3を、凸レンズ2の配列方向と微細図柄31,32の配列方向とが互いに一致するように互いに重ね合わせると、第一の微細図柄31としての数字の「2」のみが、拡大図柄31aとなって見える。第二の微細図柄32としての数字の「6」は、全く見えない。これは、第二の微細図柄32の配列ピッチと、前記レンズシート3の凸レンズ2の配列ピッチと、の関係が、前記(ハ)に該当するからである。
【0049】
なお、図3の例では、第二の微細図柄32としての数字の「6」は、レンズシート3を、図3(b)の状態から少し斜めにすれば、拡大図形として発現する。これは、前記図柄シート30と前記レンズシート3の組み合わせ角度を、微細図柄と凸レンズの配列方向が互いに少しだけずれるように変更することにより、前記第二の微細図柄32の配列ピッチを、前記凸レンズ2の配列ピッチとは異ならせたことと同じ効果が得られるからである。
【0050】
次に、図4(a)の図柄シート40においては、第一の微細図柄41として、数字の「2」が、レンズシート3における凸レンズ2の配列ピッチP(L)とは異なるピッチP1で二次元的に配列されている。同様に、第二の微細図柄42として、数字の「6」が、レンズシート3における凸レンズ2の配列ピッチP(L)とは異なるピッチP2で二次元的に配列されている。しかし、前記第一の微細図柄41の配列方向X1−Y1と前記第二の微細図柄42の配列方向X2−Y2は、互いに異なっている。
【0051】
その結果、前記第一の微細図柄41は、前記レンズシート3を前記図柄シート40に対して、図4(b)に示す第一の角度で組み合わせた時に、拡大図柄41aとなって視認可能となる。一方、前記第二の微細図柄42は、前記レンズシート3を、図4(c)に示すように、前記第一の角度とは異なる第二の角度で前記図柄シート42に対して組み合わせた時に、拡大図柄42aとして視認可能となる。
【0052】
図4の図柄シート40によれば、その面上に重ねたレンズシート3を回転させ、図柄シート40に対するレンズシート3の組み合わせ角度を変えていくと、レンズシート3における凸レンズ2の配列方向と一致した配列の微細図柄のみが、拡大図柄として視認できる。よって、隠されている図柄を探す楽しみが増し、玩具や販売促進用品や教材として適用する場合に、好適である。
【0053】
また、図4の構成は、本発明に係る被観察体を、広告手段として用いる場合にも、有効である。具体的には、例えば、前記条件を満たすように複数種類の微細図柄を付した広告を作成する。そして、前記レンズシート3に相当する視認器具を、前記広告の面上で自動的にゆっくりと回転するように配設する。このようにすれば、複数種類の図柄が時をおいて代わる代わる現れたり消えたりすることを繰り返すので、大衆の目を引き易く、大きな広告効果が得られる。
【0054】
なお、図4の図柄シート40において、前記第一の微細図柄41の配列ピッチP1と、前記第二の微細図柄42の配列ピッチP2は、互いに同じであっても違っていても良いし、それらと、前記レンズシート3における凸レンズ2の配列ピッチP(L)との大小関係も、等しくない限り、任意である。
【0055】
次に、図5(a)の図柄シート50においては、第一の微細図柄51として、数字の「2」が、レンズシート3における凸レンズ2の配列ピッチP(L)より小さいピッチP1で配列されている。加えて、第二の微細図柄52として、ハート形の図形が、レンズシート3における凸レンズ2の配列ピッチP(L)より大きいピッチP2で配列されている。さらに、前記第一の微細図柄51の配列方向と、前記第二の微細図柄52の配列方向とが、互いに同一とされている。
【0056】
図5(a)の図柄シート50と前記レンズシート3を、凸レンズ2の配列方向と微細図柄51,52の配列方向とが一致するように互いに重ね合わせると、図5(b)に示すように、第一の微細図柄51としての数字の「2」の拡大図柄51aと、第二の微細図柄52としてのハート形の図形の拡大図柄52aの双方が、その配列方向に沿って互いの重合状態をごく僅かずつずらしながらも、互いに重なり合った状態で見える。しかも、第一の微細図柄51としての数字の「2」の拡大図柄51aは引っ込んで見え、第二の微細図柄52としてのハート形の図形の拡大図柄52aは飛び出して見える。これは、第一及び第二の微細図柄51,52の配列ピッチP1,P2と、前記レンズシート3の凸レンズ2の配列ピッチP(L)と、の関係が、前記(イ)及び(ロ)に該当するからである。
【0057】
図5の図柄シート50によれば、前記第一の微細図柄51と前記第二の微細図柄52が、互いに重なり合った状態で同時に発現する。引っ込んで見える拡大図柄51aと飛び出して見える拡大図柄52aとが同時に見えるので、それらの相互作用によって、立体感が一層強調される利点がある。

[Problems to be solved by the invention]
In the above-mentioned conventional art, the hidden design is certainly easy to see by using the line film. However, it was possible to visually recognize the hidden design without using the line film, and it could not be said that the intended unexpectedness and fun were sufficiently exhibited.
[0005]
The present invention has been made in view of such circumstances, and an object of the present invention is to provide an object to be observed, which is unexpected in the appearance of a hidden symbol.
[0006]
[Means for Solving the Problems]
In order to solve the above-described problems, the observation target according to an embodiment of the present invention includes a large number of the same microscopic patterns that are difficult to see with the naked eye, two-dimensionally arranged on at least a part of the surface, and a lens. An enlarged design similar to the fine design can be visually recognized by a plurality of visual recognition devices arranged two-dimensionally (claim 1).
[0007]
In the object to be observed, a large number of the same fine patterns that are difficult to visually recognize with the naked eye are two-dimensionally arranged on the surface. When the observer sees with the naked eye, not only recognizes individual fine patterns, but also does not notice that the fine patterns are two-dimensionally arranged on the surface of the observed object. . On the other hand, when the object to be observed is viewed using the visual recognition device, when the arrangement direction of the lenses and the arrangement direction of the fine design have a predetermined relationship, an enlarged design similar to the fine design Can be recognized by the observer's eyes. Therefore, the expression of the enlarged design is sufficiently surprising.
[0008]
The specific range of application of the observed object is wide, and for example, it can be used as toys, sales promotion supplies, educational materials, etc., as advertising means and authenticity determination means. When used as advertising means, for example, the visual recognition device is disposed so as to be displaceable with respect to the observed object. By doing so, the fine design is repeatedly seen and disappeared, so that it is easy to attract the public's attention and a great advertising effect can be obtained. When used as authenticity determination means, a large number of the fine symbols are two-dimensionally arranged in advance on authentic products. By checking the presence or absence of an enlarged symbol using the visual recognition device, it is possible to easily determine whether or not the inspection object is a genuine product.
[0009]
In the present invention, the size of each lens is not necessarily the same. Similarly, the sizes of the individual fine designs do not necessarily have to be the same. In addition, the size relationship between the lens and the fine design is irrelevant.
[0010]
Further, in the present invention, the two-dimensional arrangement of the lens and the two-dimensional arrangement of the fine design need not necessarily be the same as each other, and the enlarged design can be expressed in combination with the lens sheet. May be different from each other.
[0011]
Further, in the present invention, the “fine design” includes not only pictures and figures but also characters.
[0012]
As a preferred embodiment, the surface is provided with a design that is visually recognizable by the naked eye, and both the region having the visual design and the region having the fine design are all yellow, magenta, cyan, and black. Formed by using at least one color plate of the four colors of, and printing a plate made by combining different line numbers for forming the region having the visual pattern and the region having the fine pattern It can also be formed by using (claim 2).
[0013]
With this configuration, when the visual recognition device is not used, only the naked visual design is visible, and when the visual recognition device is used, the enlarged graphic is visible in addition to the visual visual design. Therefore, the artistry is improved and the fun is increased, which is preferable. In addition, since a plate made by combining different numbers of lines for forming the region having the visual visible design and the region having the fine design is printed and produced, it can be provided at low cost.
[0014]
As a preferred embodiment, the fine design is composed of a first fine design and a second fine design arranged in a large number two-dimensionally, and the first fine design and the second fine design are , May be arranged so as to overlap each other (claim 3). In this way, the possibility of recognizing the fine design without the visual recognition device is completely lost. That is, even if only one of the first or second fine pattern is too small to be visually recognized by the naked eye, it is arranged so that the other fine pattern overlaps, and the two are in a crossed state. Because there is. Therefore, the unexpectedness of the expression of the enlarged symbol is further improved.
[0015]
The configuration is particularly effective when the object to be observed is used as authenticity determination means such as a fake product inspection means, since the recognizability of the fine pattern without the visual recognition instrument is reduced to almost zero. .
[0016]
As a preferred embodiment, the first fine design is arranged at a pitch different from the arrangement pitch of the lenses, and the second fine design is arranged at the same pitch as the arrangement pitch of the lenses, Furthermore, the arrangement direction of the first fine design and the arrangement direction of the second fine design may be the same as each other (claim 4).
[0017]
In this case, when the object to be observed is viewed using the visual recognition device, the enlarged design of the first fine design is visible, but at that time, the enlarged design of the second fine design is not visible at all.
[0018]
As a preferred embodiment, the arrangement direction of the first fine design and the arrangement direction of the second fine design are different from each other, and the first fine design makes the visual recognition instrument the observation object. Becomes visible when combined at a first angle, the second microscopic pattern, when the visual recognition device is combined with the object under observation at a second angle different from the first angle It can also be made visible (claim 5).
[0019]
In this case, by rotating the visual recognition instrument on the observation target, and changing the combination angle of the visual inspection instrument with respect to the observation target, only the fine pattern of the array that matches the arrangement direction of the visual inspection instrument, You can see it as an enlarged design. Therefore, the pleasure of searching for a different symbol increases.
[0020]
As a preferred embodiment, the first fine design is arranged at a pitch smaller than the arrangement pitch of the lenses, and the second fine design is arranged at a pitch larger than the arrangement pitch of the lenses. (Claim 6). In this case, when viewing the observed object with the visual recognition instrument, the enlarged design of the first fine design appears to be retracted, while the enlarged design of the second fine design appears to pop out, so that the three-dimensional effect is sufficient. Enjoy.
[0021]
Furthermore, the arrangement direction of the first fine design and the arrangement direction of the second fine design may be the same (claim 7). With this configuration, both the enlarged design of the first fine design and the enlarged design of the second fine design enter the observer's eyes at the same time with one retracted and the other protruding. Thereby, there is an advantage that the three-dimensional effect is further emphasized.
[0022]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a preferred embodiment of the present invention will be described with reference to the accompanying drawings.
[0023]
FIGS. 1A and 1B are plan views showing the configuration and use of a design sheet (design card) as an object to be observed according to the present embodiment, wherein FIG. 1A is a plan view of the design sheet itself, and FIG. FIG. 3C is a plan view of a lens sheet as a hidden design visual recognition tool used in combination with the design sheet, and FIG. 3C is a plan view showing a state where the lens sheet is overlaid on the design sheet. FIG. 2 is a partially enlarged sectional view of the lens sheet.
[0024]
As shown in FIG. 1A, in the present embodiment, the observed object according to the present invention is embodied as a symbol sheet (symbol card) 10 having a hidden symbol that is invisible to the naked eye. The design sheet 10 has a large number of the same fine design 11 (in the example of FIG. 1, the character “A”) that is difficult to be visually recognized by the naked eye, at least partially on the surface. . Then, by using a lens sheet 3 (see FIG. 1B) as a visual recognition tool in which a large number of fine lenses 2 are two-dimensionally arranged, as shown in FIG. An enlarged symbol 11a similar to the above becomes visible.
[0025]
In FIG. 1A, on the surface of a design sheet 10 as an object to be observed, a visual design 4 (for example, a rose flower) visually recognizable by the naked eye and a fine design 11 that is difficult to visually recognize are printed. And the like. The fine pattern 11 may be any of a picture, a figure, and a character, but in the example of FIG. 1, the character “A”, which is extremely small so as not to be seen by the naked eye, is regularly and horizontally two-dimensionally arranged. ing. When looking at the design sheet 10 without using the lens sheet 3 as a visual recognition device, the observer can see only the visible design 4 with the naked eye, and each fine design is two-dimensional at a very small pitch. Since they are arranged, the observer cannot recognize not only the fine design 11 itself but also that it is on the surface of the design sheet 10.
[0026]
On the other hand, as shown in FIG. 1C, when the lens sheet 3 is superimposed on the design sheet 10 and observed from above, an enlarged design 11a similar to the fine design 11 becomes visible by the action of the lens sheet 3. Since the lens sheet 10 has transparency, the appearance of the visible pattern 4 does not change even when it is superimposed on the design sheet 10.
[0027]
As shown in FIGS. 1B and 2, the lens sheet 3 has, for example, a large number of lenses, specifically, a dome-shaped or convex lens 2 on a surface of a transparent sheet-shaped base material 5. , And are arranged two-dimensionally and regularly. Although the individual lenses 2 are extremely small, the larger the thickness TL is, the more the enlarged visibility of the fine design 11 is improved. It is desirable that the arrangement pitch P (L) of the convex lenses 2 is also small as long as the adjacent convex lenses do not interfere with each other. Although not limited, as an example, if a numerical value is given, for example, the thickness TL of the convex lens is 60 μm, the size (diameter) D in plan view is 400 μm, and the vertical and horizontal arrangement pitch P (L) is 500 μm. it can. In this case, if the individual convex lenses 2 are considered as halftone dots, it can be said that the convex lenses 2 are arranged or formed with 50.8 lines (/ inch). The thickness TB of the sheet-like substrate 5 is, for example, 0.8 to 1.2 mm.
[0028]
The lens sheet 3 is known per se. For example, a transparent material such as an ultraviolet-curable resin ink is coated on the surface of a transparent sheet-like base material 5 made of plastic or the like by using a screen printing method. The convex lens 2 can be formed by attaching the convex lens 2 in a dome shape.
[0029]
In the example of FIG. 1, the arrangement pitch P of the fine patterns 11 is different from the arrangement pitch P (L) of the convex lenses 2. Although not limited, specifically, considering that each fine pattern 11 is a halftone dot, when the number of lines of the convex lens 2 of the lens sheet 3 is 50.8 lines, the fine pattern 11 , For example, 44 to 49 lines (/ inch) or larger than the number of lines of the convex lens, for example, 52 to 55 lines (/ inch). Note that a large number of lines is synonymous with a small two-dimensional array pitch, and a small number of lines is equivalent to a large two-dimensional array pitch.
[0030]
In general, when a fine design is viewed using a lens sheet, the fine design depends on the magnitude relationship between the arrangement pitch of the convex lenses in the lens sheet and the arrangement pitch of the fine designs in the design sheet. The appearance of changes. As a result of the inventors of the present invention creating and testing various actual products, the following facts were confirmed.
[0031]
(A) When the arrangement pitch of the fine design is larger than the arrangement pitch of the convex lenses, when the two are overlapped so that the arrangement direction of the convex lens and the arrangement direction of the fine design coincide with each other, the enlarged design of the fine design becomes Looks popping out.
[0032]
(B) When the arrangement pitch of the fine patterns is smaller than the arrangement pitch of the convex lenses, when the two are overlapped so that the arrangement direction of the convex lenses and the arrangement direction of the fine patterns coincide with each other, the enlarged pattern of the fine patterns becomes Looks retracted.
[0033]
(C) When the arrangement pitch of the fine patterns is the same as the arrangement pitch of the convex lenses, when the two are overlapped so that the arrangement direction of the convex lenses and the arrangement direction of the fine patterns coincide with each other, an enlarged pattern of the fine patterns is obtained. Does not appear.
[0034]
According to the experiments performed by the inventors of the present invention, the size of each lens in the lens sheet is not always strict as a condition for allowing the fine design attached to the design sheet to be visually recognized as an enlarged design on the lens sheet. It does not have to be the same. The planar shape of each lens is not limited to a circle, but may be another shape such as a square or a hexagon. Similarly, the size of each fine design is not necessarily strictly the same. Further, the magnitude relationship between each lens and each fine pattern is not questionable. Furthermore, the two-dimensional arrangement pitch of the lens and the fine design is usually the same between a first direction (for example, a vertical direction) and a second direction (for example, a horizontal direction) orthogonal to each other. However, they are not necessarily the same. In short, in the present invention, a set of substantially the same fine patterns that are so small as to be invisible to the naked eye on the surface, when viewed through the set of fine lenses on the surface, an enlarged pattern similar to the fine pattern is observed. Anything that is visible to the person is acceptable.
[0035]
The design sheet 10 is not limited, but can be created, for example, as follows. First, a plate corresponding to the region having the visible visual pattern 4 is formed using at least one color plate of four colors of yellow, magenta, cyan, and black. The number of lines forming the visible pattern 4 is not limited. However, after printing, the pattern can be formed with the number of lines that can be seen clearly and beautifully when viewed with the naked eye, for example, 175 lines (/ inch). .
[0036]
The plate corresponding to the region having the fine pattern 11 is also formed using at least one of the four colors of yellow, magenta, cyan, and black. For example, when it is desired to display the fine design in black, the fine design may be displayed in black on a black film. On the other hand, if it is desired to display the fine design 11 in the ground color, the film of the color to be used only needs to pass through the shape corresponding to the fine design 11. When it is desired to display the fine design 11 in another color, the fine design 11 may be displayed on a film of a color necessary to obtain the color.
[0037]
Next, a plate in which the numbers of lines different from each other of the number of lines for forming the region having the visual visible design 4 and the number of lines for forming the region having the fine design 11 are made, For example, an offset printing machine is used to print on a base material for forming a design sheet. According to such a production method, since the fine design 11 portion and the visible design 4 portion having different numbers of lines are printed simultaneously on the base material by one printing, the design sheet 10 can be manufactured at low cost. Can be provided.
[0038]
The symbol sheet 10 allows the user to enjoy the unexpectedness and variety of hidden symbol expression, so that the symbol sheet 10 can be used as a toy, a sales promotion article, a teaching material, or the like. However, the scope of application of the present invention is not limited to these, and can be applied as advertising means, counterfeit inspection means (authenticity determination means), and the like.
[0039]
When used as an advertising means, for example, the observation object is formed large, and automation is performed so that the visual recognition device repeatedly overlaps and separates from the observation object. In this way, a fine design is seen or disappeared as an enlarged design by an observer of the advertisement, so that the viewer's interest and attention can be easily drawn, and a large advertisement effect can be obtained.
[0040]
When used as a fake product inspection means, a large number of fine designs are two-dimensionally arranged in advance on a genuine product. By checking the presence or absence of the appearance of an enlarged symbol using a visual recognition device, it is possible to easily and reliably determine whether or not the inspection object is a genuine product.
[0041]
Next, another embodiment of the present invention will be described with reference to FIGS.
[0042]
3 to 5 are plan views each showing a design sheet according to another embodiment of the present invention and a method of using the same. Hereinafter, the lens sheet for viewing these design sheets is the same as that described above with reference to FIGS. 1B and 2.
[0043]
The three symbol sheets 30, 40, and 50 shown in FIGS. 3 to 5 have one common feature. That is, as shown in the enlarged state of (a) in each figure, the same first fine patterns 31, 41, 41, which are hardly visible to the naked eye, are provided on the surfaces of these pattern sheets 30, 40, 50. A large number of 51s are two-dimensionally arranged, and a large number of the same second fine patterns 32, 42, 52 which are difficult to visually recognize with the naked eye. Moreover, the first fine patterns 31, 41, 51 and the second fine patterns 32, 42, 52 are arranged such that the individual patterns overlap each other. For this reason, the possibility of recognizing the fine pattern without the lens sheet 3 is completely lost. That is, even if only one of the first or second fine pattern is too small, even though it is difficult to see with the naked eye, it is arranged so that the other fine pattern overlaps, This is because they are intersected. Therefore, when the lens sheet 3 is superimposed on the design sheets 30, 40, and 50, the unexpectedness of the appearance of the design is further improved, and the lens sheet 3 is suitable for use as a toy or a sales promotion article.
[0044]
The configuration common to FIGS. 3 to 5 is also suitable for the case where the observed object according to the present invention is used as authenticity determination means such as counterfeit inspection means. That is, a genuine product is provided with a first fine design and a second fine design in advance in such a manner as to satisfy the above-described conditions. The first fine pattern and the second fine pattern are so small that each is invisible to the naked eye, and because they are arranged so as to overlap each other, for a counterfeit manufacturer, without a lens sheet It is almost impossible to detect the presence of a fine pattern in a genuine product and its specific shape. Therefore, a fine design cannot be attached to a counterfeit product imitating a genuine product. If the inspected object is a genuine product, the inspector can confirm the enlarged design of the first fine design by looking at using the lens sheet, but if the inspected product is a counterfeit product, , No pattern is expressed.
[0045]
In addition, in each of the examples of FIGS. 3 to 5, the types of the fine symbols are the first and second types, but it is needless to say that three or more types may be used.
[0046]
Next, a configuration unique to each of the symbol sheets of FIGS. 3 to 5 will be described.
[0047]
In the symbol sheet 30 of FIG. 3A, the number “2” is two-dimensionally arranged as a first fine symbol 31 at a pitch P1 different from the array pitch P (L) of the convex lenses 2. I have. In addition, as a second fine design, the numeral "6" is two-dimensionally arranged at the same pitch P2 as the arrangement pitch P (L) of the convex lenses 2. Further, the arrangement direction of the first fine symbols 31 is the same as the arrangement direction of the second fine symbols.
[0048]
As shown in FIG. 3B, the design sheet 30 of FIG. 3A and the lens sheet 3 are overlapped so that the arrangement direction of the convex lenses 2 and the arrangement direction of the fine designs 31 and 32 coincide with each other. Only the numeral “2” as the first fine symbol 31 appears as the enlarged symbol 31a. The number “6” as the second fine pattern 32 is not visible at all. This is because the relationship between the arrangement pitch of the second fine symbols 32 and the arrangement pitch of the convex lenses 2 of the lens sheet 3 corresponds to the above (c).
[0049]
In the example of FIG. 3, the numeral “6” as the second fine pattern 32 appears as an enlarged figure when the lens sheet 3 is slightly inclined from the state of FIG. 3B. This is because by changing the combination angle of the design sheet 30 and the lens sheet 3 so that the arrangement direction of the fine design and the convex lens is slightly shifted from each other, the arrangement pitch of the second fine design 32 is changed to the convex lens. This is because the same effect as that obtained by making the arrangement pitch different from the second arrangement pitch can be obtained.
[0050]
Next, in the design sheet 40 of FIG. 4A, as the first fine design 41, the numeral “2” is set at a pitch P 1 different from the arrangement pitch P (L) of the convex lenses 2 in the lens sheet 3. They are arranged in a dimension. Similarly, as the second fine pattern 42, the numeral “6” is two-dimensionally arranged at a pitch P2 different from the arrangement pitch P (L) of the convex lenses 2 in the lens sheet 3. However, the arrangement direction X1-Y1 of the first fine design 41 and the arrangement direction X2-Y2 of the second fine design 42 are different from each other.
[0051]
As a result, the first fine pattern 41 becomes visible as an enlarged pattern 41a when the lens sheet 3 is combined with the pattern sheet 40 at a first angle shown in FIG. 4B. Become. On the other hand, as shown in FIG. 4C, the second fine pattern 42 is formed when the lens sheet 3 is combined with the pattern sheet 42 at a second angle different from the first angle. , And become visible as the enlarged symbol 42a.
[0052]
According to the design sheet 40 of FIG. 4, when the lens sheet 3 superimposed on the surface is rotated and the combination angle of the lens sheet 3 with respect to the design sheet 40 is changed, the arrangement direction of the convex lenses 2 in the lens sheet 3 matches. Only the fine symbols in the arrangement are visible as enlarged symbols. Therefore, the pleasure of searching for a hidden pattern increases, and it is suitable when applied as a toy, a sales promotion article, or a teaching material.
[0053]
The configuration shown in FIG. 4 is also effective when the observed object according to the present invention is used as an advertising unit. Specifically, for example, an advertisement with a plurality of types of fine symbols is created so as to satisfy the above condition. Then, a visual recognition device corresponding to the lens sheet 3 is disposed so as to automatically and slowly rotate on the surface of the advertisement. In this way, the plural kinds of symbols alternately appear and disappear alternately with time, so that the public can be easily noticed and a great advertisement effect can be obtained.
[0054]
In the design sheet 40 of FIG. 4, the arrangement pitch P1 of the first fine design 41 and the arrangement pitch P2 of the second fine design 42 may be the same or different from each other. And the arrangement pitch P (L) of the convex lenses 2 in the lens sheet 3 are also arbitrary as long as they are not equal.
[0055]
Next, in the design sheet 50 of FIG. 5A, the number “2” is arranged at a pitch P1 smaller than the arrangement pitch P (L) of the convex lenses 2 in the lens sheet 3 as the first fine design 51. ing. In addition, a heart-shaped figure is arranged at a pitch P2 larger than the arrangement pitch P (L) of the convex lenses 2 on the lens sheet 3 as the second fine symbol 52. Further, the arrangement direction of the first fine symbols 51 and the arrangement direction of the second fine symbols 52 are the same as each other.
[0056]
When the design sheet 50 and the lens sheet 3 of FIG. 5A are overlapped with each other so that the arrangement direction of the convex lenses 2 and the arrangement direction of the fine designs 51 and 52 match, as shown in FIG. Both the enlarged design 51a of the number “2” as the first fine design 51 and the enlarged design 52a of the heart-shaped graphic as the second fine design 52 are in a state of being overlapped with each other along the arrangement direction. Appear to overlap each other, even if they are slightly shifted. In addition, the enlarged design 51a of the number “2” as the first fine design 51 appears to be retracted, and the enlarged design 52a of the heart-shaped graphic as the second fine design 52 appears to pop out. This is because the relationship between the arrangement pitches P1 and P2 of the first and second fine patterns 51 and 52 and the arrangement pitch P (L) of the convex lenses 2 of the lens sheet 3 is as described in (a) and (b) above. This is because
[0057]
According to the design sheet 50 of FIG. 5, the first fine design 51 and the second fine design 52 are simultaneously expressed in a state where they overlap each other. Since the enlarged design 51a that is seen to be retracted and the enlarged design 52a that is seen to pop out are seen at the same time, there is an advantage that the three-dimensional effect is further emphasized by their interaction.
