【発明の実施の形態】本発明における基本的な実施の形態は、図1に示すように、着色又は無着色の透明基板B The basic embodiment of the DETAILED DESCRIPTION OF THE INVENTION The present invention, as shown in FIG. 1, a colored or uncolored transparent substrate B
(以下「基板」と略す)の表面に、凸レンズの役割を果す透明性を有する着色又は無着色の多数の凸状集光素(以下「集光素」と略す)Aを一定ピッチにて規則正しい配列状態に印刷し、該基板Bの裏面に、前記表面の集光素Aと同配列状態の多数の着色画素(以下「画素」と略す)Cを表面の集光素Aに対し交差角を少しずらせて印刷することにより、前記画素Cが、表面から見て立体感を有する拡大画像として現出し視点を移動させると該拡大画像が揺らぎ感を呈する点描画模様の装飾体が得られる。 On the surface (hereinafter referred to as "substrate"), a number of convex condensing element of colored or uncolored having transparency to fulfill the role of a convex lens (hereinafter referred to as "light condensing element") ordered at constant pitch A printed on arrangement state, the rear surface of the substrate B, and the crossing angle with respect to a large number of colored pixels (hereinafter referred to as "pixels") C the surface of the light condensing elements a light condensing element a and the arrangement of said surface by printing is slightly shifted, the pixel C is decorations drawing pattern that exhibits the current out when the viewpoint is moved the enlarged image fluctuation feeling as an enlarged image having a stereoscopic effect when viewed from the surface.

【0013】本発明により現出される点描画模様とは、 [0013] and the point drawing pattern which is to appear in accordance with the present invention,
画素Cが一色の円形ドットの場合には、一定配列の画素Cと一定配列の集光素Aの交差角のずれにより、大きさ、濃淡が変化し、規則性のある立体感を有する拡大された水玉模様が基板Bの上面に現出し、視点を移動させることにより前記拡大された水玉模様が移動して揺らぎ感のある模様となるものである(図5参照)。 If the pixel C is the color of the circular dots, the shift of the intersection angle of the light condensing elements A constant array with the pixel C of the constant array, the size, shading changes are magnified with a stereoscopic effect having regularity was polka dots out current on the upper surface of the substrate B, the enlarged polka dots and serves as a pattern with a sense of fluctuation moved by moving the viewpoint (see FIG. 5).

【0014】さらに、基板Bの裏面に2種以上の一定配列の画素Cを用い、この画素Cに対し一定配列の集光素Aの交差角を変化させて重ねると、画素Cを構成する色彩の点模様が交差点を中心として対称的に組み込みまれ、規則正しく配列した縞模様等種々の組み込み点描画となり、しかも、これらの点模様が視野を変えると揺らぎ感を生じる。 Furthermore, using the pixel C of the back to two or more predetermined sequences of substrate B, and overlapped by changing the crossing angle of the light condensing elements A constant array to the pixel C, the color constituting the pixel C point pattern symmetrically embedded rare around the intersection, becomes regularly arranged the stripes like various built-point drawing, moreover, results in fluctuations sense when these points pattern changing field of view.

【0015】また、本発明における別の実施形態として、前記図1と同様に、着色又は無着色の基板Bの表面に、凸レンズの役割を果す透明性を有する着色又は無着色の多数の集光素Aを一定ピッチにて規則正しい配列状態に印刷すると共に、該基板Bの裏面にも、前記図1の画素Cに代えて表面の集光素Aと同形状で同配列状態又は異形状で同配列状態の凸レンズの役割を果す透明性を有する着色又は無着色の多数の集光素A'(図示せず) Further, as another embodiment of the present invention, similar to FIG. 1, colored or non-colored surface of the substrate B, the number of condensing colored or uncolored having transparency play a role of a convex lens with printing the element a to the regular array state at a constant pitch, also the rear surface of the substrate B, and the surface instead of the pixel C of Figure 1 light condensing element a and the arrangement state or irregular shape in the same shape the multiple light condensing element a colored or uncolored having transparency play a role of the convex lens array state '(not shown)
を、表面の集光素Aに対し交差角を少しずらせて印刷することにより、表裏いずれの面から見ても前記凸状集光素Aと凸状集光素A′が合成された形態の立体感を有する拡大画像が現出し、視点を移動させると該拡大画像が揺らぎ感を呈する点描画模様の装飾体が得られる。 And by printing slightly by shifting the crossing angle with respect to light condensing elements A surface, front and back either be seen from the surface the convex condensing element A and a convex condenser element A 'is form synthesis out larger image current having a three-dimensional effect, decorations points drawing pattern exhibits a sense moving the enlarged image fluctuation viewpoint is obtained.

【0016】前記の拡大された点描画模様の揺らぎ現象は、レンズ効果を有する集光素A又はA'を介して見える残像効果による錯覚により生じると考えられる。 [0016] The fluctuation phenomenon of the expanded terms drawn pattern is believed to be caused by the illusion by afterimage effect visible through the light condensing element A or A 'has a lens effect. 又、 or,
点描画模様の立体感は、基板Bに一定ピッチにて規則正しい配列状態に印刷された集光素Aのレンズ効果により、画素Cと視点(目)間に焦点の異なる像を形成する結果、ドット輪郭が拡大されてぼやけた特殊な模様になると考えられる。 Point stereoscopic effect of drawing pattern is by the lens effect of the regular printed arrangement state the light condensing element A at a predetermined pitch on the substrate B, result in the formation of focal different image between the pixel C and the viewpoint (eye), dot It is considered to be a special pattern contours blurred been enlarged.

【0017】本発明における基板Bの材質としては、可視光が透過すれば良く、着色されたものでも透明であれば無機質、有機質に限定されず、ガラス板、樹脂板、フィルム等任意のものが利用でき、入手や加工のしやすい点でポリエステルフィルム、アクリルフィルム、ポリカーボネート板等が便利であるが特に制限されない。 [0017] As material of the substrate B in the present invention may be transmitted visible light, be transparent even those that are colored inorganic, is not limited to organic, glass plate, a resin plate, those films any available, the polyester film in that easily availability and processing, an acrylic film, although a polycarbonate plate or the like is convenient not particularly limited.

【0018】本発明の基板Bで重要なことは厚みである。 [0018] In the substrate B of the present invention it is important it is the thickness. この基板Bの厚みは、画素Cの直径、集光素Aの直径と高さ等により点描画像の形態に大きく影響するため特定出来ないが、画素Cや集光素Aの直径より厚い方が望ましい。 The thickness of the substrate B, the diameter of the pixel C, but can not be specified to greatly affect the form stippled image by the diameter and height, etc. of the light condensing element A, it is thicker than the diameter of the pixel C and light condensing element A desirable.

【0019】この基板Bは、厚ければ厚いほど揺らぎが顕著になるが、厚すぎると画像がぼやけたり、色がうすくなったり、又、取り扱いが不便となり、逆に薄すぎると点描効果が現れにくく、平印刷の感じとなり揺らぎも少なくなる。 [0019] The substrate B is The thicker fluctuation becomes noticeable, or blurred too thick image, or color becomes thin, and the handling becomes inconvenient, appear with stippled effect it is too thin Nikuku, fluctuations become a feeling of flat printing is also reduced.

【0020】従って、基板Bの厚さとしては10μm 〜 [0020] Therefore, as the thickness of the substrate B 10μm ~
10mmのものが適用できるが、好ましくは50μm 〜5 Can be applied include the 10 mm, preferably 50 [mu] m to 5
mmのものが実用的である。 Those mm is practical.

【0021】本発明における画素Cには、図2に示すような円形、四角形、星形をはじめ三角形、楕円形、線形その他任意形状のものが適用可能であるが、画素Cの長径が0.1μm 〜1mm、好ましくは1μm 〜100μm [0021] pixel C in the present invention can be circular as shown in FIG. 2, square, star-shaped and began triangular, elliptical, although linear any other shape that is applicable, the major axis of the pixel C 0. 1μm ~1mm, preferably 1μm ~100μm
で、基板Bの厚みの1/2以下、好ましくは1/5以下であり、画素Cが大きすぎると点描画の像が乱れ、あまり小さいのは印刷技術上の問題から制限される。 In, half or less of the thickness of the substrate B, preferably 1/5 or less, disturbed image stippled image with pixel C is too large, the too small is limited from problems on the printing technology.

【0022】この画素Cの高さは特に制限されないが、 The height of the pixel C is not particularly limited,
印刷適性の関係から画素Cの直径の1/10〜1/2程度が通常利用できる高さである。 About 1 / 10-1 / 2 of the diameter of the pixel C from the relationship of printability is height usually available.

【0023】集光素A及び画素Cは、基板Bの平面に一定ピッチにて規則正しく多数配列されており、この集光素Aと画素Cとの交差角(θ)は、45°以上になると同じパターンの繰り返しとなるため、0<θ<45°の範囲に限られる。 The light condensing element A and pixel C are plane are arranged regularly number at a constant pitch of the substrate B, the crossing angle between the light condensing element A and the pixel C (theta) is, at the 45 ° or higher since the repetition of the same pattern, 0 <θ <limited to the range of 45 °.

【0024】なお、画素Cを2種以上印刷する場合、隣接する画素C同志は互いに接していても、離れていても良いが、その間隔が画素Cの長径の2倍以上になると、 [0024] In the case of printing a pixel C 2 or more, even if the adjacent pixels C comrades in contact with each other, may be separated, but when the interval is more than 2 times the diameter of the pixel C,
点描画の像が乱れやすいのでそれ以内にすべきである。 Since the pointillist painting of the image is easily disturbed it should be within it.

【0025】また、前記2種以上の画素Cの組み合わせに際しては、同じ配向性でも又異なった配向性でもよいが、配向性を異なったものとすると集光素Aとの交差角によっては画素Cの形状の明瞭さがなくなり複雑な模様となる。 Further, when a combination of the two or more pixel C may be also different orientation even with the same orientation, but the pixel C is the intersection angle between the light condensing element A when made to different orientation clarity of shape is a complicated pattern no longer of.

【0026】なお、本発明では、2種以上の画素Cを組み合わせて用いる場合には、同一の基板Bの裏面に重ね刷りする方式でも良いが、図3に示すように、別の基板B'に印刷したものを基板Bの裏面に重ねても良い。 [0026] In the present invention, when used in combination of two or more pixels C, or in a manner that overprinting on the back surface of the same substrate B, but as shown in FIG. 3, another substrate B ' the may be superimposed on the back surface of the substrate B that is printed on.

【0027】集光素Aの形状・配列は、画素同様任意であり所望する点描画模様により決定されるが、一般に画素Cと同形状で同配列のものとするのが印刷上簡単であり、この場合でも、画素Cと集光素Aとの交差角をずらす量により点描画模様として見える画素Cの大きさや輪郭の状態は変化する。 The light condensing element A shape and arrangement of, but is determined by the drawing pattern points to the desired a pixel similar optional, generally to those of the same sequence in the pixel C and the same shape is simple typographical even in this case, the size and contour of the state of the pixel C appear as stippled image pattern by the amount of shifting the crossing angle between the pixel C and the light condensing element a varies.

【0028】したがって、本発明においては基板Bの裏面に複数の画素Cを印刷する際、画素Cの形状として、 [0028] Therefore, when printing a plurality of pixels C on the back surface of the substrate B in the present invention, the shape of the pixel C,
各種の文字や図柄の部分とそれ以外の地部分とに、例えば同一ピッチにて同形状で同配列の画素Cを相互の角度を少しずらせて印刷し、基板Bの表面には前記裏面の複数の画素Cのうちいずれかの画素Cと同形状で同配列の集光素Aを、前記複数の画素Cのいずれとも少し交差させて印刷することにより、前記文字や図柄の部分とそれ以外の地の部分とで図5に示すように異った大きさの拡大された点描画模様が得られ、かつ、それぞれの点描画模様における立体感と揺らぎ感についても異った状態を呈するものが得られる。 To the various characters and symbols portion and the other land portion, for example by printing slightly by shifting the mutual angle pixel C of the same sequence in the same shape at the same pitch, a plurality of the back on the surface of the substrate B of the light condensing elements a in sequence in one of the pixel C and the same shape of the pixels C, by printing with any and also to slightly intersections of the plurality of pixels C, the letters and figures parts and other land portions and enlarged points drawn pattern size were different Tsu as shown in FIG. 5 is obtained, and those that exhibit a state also Tsu different stereoscopic feeling and fluctuation feeling in each point drawing pattern can get.

【0029】前記の場合、文字や図柄(図5中央の星形)の輪郭部分Fをベタ刷にて縁取して文字や図柄を引き立つようにしてもよいし、又、集光素Aの印刷範囲を文字や図柄の部分の上面のみに設ければ、文字や図柄の部分のみに拡大された立体感と揺らぎ感を呈する点描画模様が得られる。 In the case of the character and patterns to the contour portion F (Fig. 5 middle of the star) may be sets off the characters and patterns and edging in solid printing, and printing of the light condensing element A by providing a range only on the upper surface of the portion of the character or symbol, drawing pattern that exhibits only stereoscopic feeling and fluctuation feeling which is enlarged in a portion of the character or pattern is obtained.

【0030】集光素Aの材質は、前記基板Bと同様に可視光が透過すればよく、無色でも着色されたものでもよいが、印刷により凸状に設ける必要があるため、前記基板Bに対する印刷特性の良いインキであることが条件となる。 The material of the light condensing element A, the substrate B and may be visible light transmission as well, may be one which is colored in a colorless, but it is necessary to provide a convex shape by printing, for the substrate B it is a condition which is a good ink by the print properties. 従って、本発明においては密着性、透明性及び厚盛性のよいインキであれば特に限定されない。 Therefore, it not particularly limited as long as adhesion, transparency and AtsuSakari having good ink in the present invention.

【0031】また、この集光素Aについても、2種以上の形状のものを重ならないように配列しても良いが、この場合画素Cとの組み合せにより複雑で多様な点描画模様となる。 Further, this light condensing elements A may also be arranged so as not to overlap those of two or more shape, becomes complicated and diverse points drawing pattern by the combination of this case pixel C.

【0032】さらに、集光素Aとして着色透明インキを用いた場合や、基板Bとして着色透明基板を用いた場合には、それぞれ画素Cの色と合成された色彩の点描画模様が得られる。 Furthermore, and in the case of using a colored transparent ink as light condensing element A, in the case of using a colored transparent substrate as the substrate B is a point drawing pattern colors that are respectively combined with the color of the pixel C is obtained.

【0033】なお、基板Bに対する集光素Aや画素Cの形成手段としては、周知のスクリーン印刷や転写印刷が適用できる。 [0033] As the means for forming the light condensing element A and pixel C with respect to the substrate B, it can be applied well-known screen printing or transfer printing.

【0034】本発明により現出する点描画模様については、将来は光学理論により解明され、集光素や基板の屈折率、集光素の形状や高さ、基板の厚み、画素の形状、 [0034] For drawing pattern points to emerge by the present invention, the future is solved by the optical theory, the refractive index of the light condensing element and the substrate, light condensing element the shape and height, substrate thickness, the shape of the pixel,
画素と集光素の配列や交差角により計算可能と考えられるが、現段階ではあまりにも複雑であり経験則に頼らざるを得ない。 Considered it can be calculated by sequencing and crossing angle of the pixel and light condensing element, but must rely on too complicated heuristics at this stage.

【0035】しかし、点描画模様の決定法として、以下の方法が便利である。 [0035] However, as a method of determining the point drawing pattern, the following method is convenient. まず、2枚の薄い基板に集光素と画素を別々に印刷したものを用意し、画素面側に集光素を印刷した基板側の裏面が接する様に重ね、どちらか片方をずらして配向軸を交差させると模様が種々変化するので所望の点描画模様となる交差角を定め、製品としては、同一基板の表裏両面に、画素と集光素を前記交差角と同じだけずらせて直接印刷することにより前記と同様の点描画模様を再現させる。 First, the light condensing elements and pixels two thin substrates Prepare a printed separately, stacked as contact is the back surface of the substrate were printed light condensing element side to the pixel side, oriented by shifting either one since the cross the axis pattern is changed variously define the crossing angle as the desired point drawing pattern, printed as the product, on both sides of the same substrate, directly by shifting the pixel and light condensing element by the same and the cross angle wherein a to reproduce the same point drawing pattern by.

【0036】この場合、2種の画素を利用するときには、まず、薄い2枚の基板に2種の画素を別々に印刷し、これを適宜ずらせて重ねると共に、この重ねた画素の上面に、集光素を印刷した基板の裏面を重ね、各基板をずらせて画素と集光素の交差角を変えることにより所望の点描画模様を決定し、製品としては、同一基板の裏面に2種の画素をずらせて重ね刷りし、その基板の表面に集光素を印刷して前記と同様の点描画模様を再現させる。 [0036] In this case, when utilizing the two pixels, first, thin two substrates were printed separately two pixels, with overlap to be shifted so as appropriate, on the top surface of the overlapping pixels, collecting overlapping the rear surface of the substrate printed with light element, each substrate by shifting to determine the desired point drawing pattern by changing the crossing angle of the pixel and the focusing element, as a product, the two pixels on the rear surface of the same substrate the overprinted by shifting, by printing a light condensing element to reproduce the point drawing pattern similar to the the surface of the substrate.

【0037】更に、これら集光素A、基板B、画素Cの組み合せについては任意の組み合せ形態が可能であり、 Furthermore, these condensing element A, the substrate B, and combinations of pixel C is capable of any combination form,
例えば図4に示すように基板Dの表面に画素Cを印刷し、その上部に透明インキEを全面印刷し、その上面に集光素Aを印刷する構成としても、前記と同様の点描画模様が得られる。 For example to print a pixel C on the surface of the substrate D as shown in FIG. 4, the entire surface printed transparent ink E thereon, be configured to print a light condensing element A on its upper surface, by the same point drawing pattern It is obtained.

【0038】本発明においては、レンズ効果を果す集光素Aを印刷により設けることができるため、前述のように1枚の基板Bに対し、部分的に集光素Aの直径、高さ、色、形状、配列状態など任意、かつ容易に変えることができるため、装飾体としてのデザインの自由度が増す。 [0038] In the present invention, it is possible to provide by printing light condensing element A to play a lens effect with respect to one substrate B as described above, partially diameter of light condensing element A, height, color, shape, it is possible to change such as any, and easily arranged state, the degree of freedom of design of the decorative member is increased.

【0039】なお、前記原理を用い、画素側基板と集光素側基板の一方、又は双方を回転させる機構を採用することにより、動く点描画模様を得ることができるので玩具などに利用することも出来る。 It should be noted, using the principle, one pixel-side substrate and the condensing Motogawa substrate, or by employing a mechanism for rotating both, be utilized such as toys it is possible to obtain a point drawing pattern moving can also.

【0040】以下、本発明の前記基本形態における各構成要素の種々の組み合せ条件による、点描画模様の立体感、画像の鮮明度、揺らぎ感、模様の大きさ等につき実験した結果を示す。 [0040] Hereinafter, according to the various combinations condition of each component in the basic mode of the present invention, three-dimensional appearance of the point drawing pattern, the sharpness of the image, the fluctuation sense, the results of the experiments per size of the pattern.

【0041】表1は、厚さ1mmのポリカーボネート製基板Bの表面に、集光素Aとして十条化成(株)製410 [0041] Table 1, the polycarbonate substrate surface B having a thickness of 1 mm, Jujo Kasei as light condensing element A (KK) 410
0番シリーズの透明インキを用い、ドットが30線で直径250μm 、60線で直径120μm 、120線で直径60μm 、高さをそれぞれ30μm の円弧状とし、画素としてそれぞれ前記と同じ直径で、高さ3μm の円形ドットを印刷した場合における集光素Aと画素Cの一軸交差による点描画模様の大きさを示す表で、この表をグラフ化したのが図6に示すものである。 A transparent ink zeroth series, dot diameter 250μm at 30 wire diameter 120μm in 60 lines, diameter 60μm at 120 lines, and a height of each 30μm arcuate, with the same diameter as defined above as a pixel, the height in table showing the size of the drawing pattern point by uniaxial intersection light condensing element a and the pixel C in the case of printing a circular dot of 3 [mu] m, for this table was graphed is as shown in FIG.

【0042】 [0042]

【表1】 [Table 1]

【0043】このグラフから、集光素Aと画素Cの交差角度が同じ場合、模様の大きさは線数(ドットの数)に対して反比例すること、及び線数とパーセント(単位面積当りの集光素又は画素の占める割合)が同じ場合、模様の大きさは交差角に対して反比例することがわかる。 [0043] From this graph, when the crossing angle of the light condensing element A and pixel C are the same, the size of the pattern is the number of lines to be inversely proportional to (number of dots) of, and the number of lines and percentage (per unit area light condensing element or proportion of pixels) if the same, it can be seen that the size of the pattern is inversely proportional to the intersection angle.

【0044】表2は、ポリカーボネート製基板Bの厚みによる点描画模様の見え方を示すもので、集光素Aと画素Cが60線30%の条件にて形成された円形ドットを約30cm離れて垂直方向から見た状態を示すものである。 [0044] Table 2 shows the appearance of the drawing pattern point by the thickness of the polycarbonate substrate B, about 30cm away a circular dot light condensing element A and the pixel C are formed in 60 lines of 30% conditions It shows a state viewed from the vertical direction Te.

【0046】この表から拡大画像としての点描画模様の立体感については、基板Bの厚みが3mmより厚くても、 [0046] For stereoscopic effect of point drawing pattern as an enlarged image from the table, even if the thickness of the substrate B is thicker than 3 mm,
又、0.188mmより薄くても悪くなり、揺らぎ感については、薄いものより厚いものの方が大きくなるが、視点がずれるにつれて画像の確認が困難になる。 In addition, even worse thinner than 0.188mm, for the fluctuation sense, but more of thicker than thin ones increases, the confirmation of the image becomes difficult as the viewpoint shifts.

【0047】なお、前記実験の際、集光素Aの形態を半球状に近ずける程、立体感や揺らぎ感が大きくなることを確認した。 [0047] At the time of the experiment, near-not a Keru extent to form hemispherical light condensing element A, it was confirmed that the three-dimensional effect or vibration sensation increases. 従って、この集光素Aの高さと基板Bの厚みにより点描画模様の立体感や揺らぎ感は影響を受ける。 Thus, three-dimensional appearance or vibration sensation stippled image pattern by the height and thickness of the substrate B in the light condensing element A is affected.

【0048】表3は、厚さ1mmのポリカーボネート製基板Bにおける集光素A及び画素Cの線数とパーセントの関係による点描画模様の鮮明度を示すものである。 [0048] Table 3 shows the definition of the drawing pattern point by the line number and percentage of the relationship between light condensing elements A and pixel C in polycarbonate substrate B having a thickness of 1 mm.

【0051】しかし、これら表2、表3における良し悪しの評価は、複数の研究者の個人的な主感によるもので:表中△にて表示されたものでも画像の輪郭は多少ぼけるが、使用目的によっては利用価値を有するものである。 [0051] However, these Table 2, the evaluation of the good and bad in Table 3, due to the personal main sense of multiple researchers: the outline of the also image which has been displayed in the table △ is somewhat blurred, in some applications and has a utility value.

【0052】前記の結果は、集光素Aとして、透明インキによりドットが30線で直径250μm 、60線で直径120μm 、120線で直径60μm 、高さをそれぞれ30μm の円形ドットを円弧状に印刷し、画素Cとして、それぞれ前記と同じ直径で、高さ3μm の円形ドットを印刷した場合のものについて実験したものであるが、画素を図2の(B)に示す四角形や図2の(C)に示す星形にしても同じ傾向を示した。 [0052] The results, as light condensing element A, the dot diameter 250μm in 30 lines of a transparent ink, the diameter 120μm in 60 lines, print diameter 60μm at 120 lines, each circular dot of 30μm height arcuately and, as a pixel C, and the same diameter as defined above, but is obtained by experiment for those in the case of printing a circular dot height 3 [mu] m, in FIG. 2 pixels square and in Figure 2 shown in (B) (C even if the star-shaped as shown in) showed the same trend.
