Description

  The present invention relates to a decorative body.

  As is well known, as one of decorative bodies used for advertising boards, an image is obtained by laminating a pixel layer formed by aligning a plurality of pixels and a plano-convex lens layer formed by aligning a plurality of plano-convex lenses. Decorative bodies that appear are known.

  For example, in the following Patent Document 1, a large number of independent colored or non-colored convex condensing elements A having regularity are regularly arranged on a surface of a colored or non-colored transparent substrate B at a constant fine pitch. A plurality of colored pixels C having the same shape as the convex condensing element A on the front surface or the same arrangement state or different shape on the back surface of the transparent substrate B are printed on the back surface of the transparent substrate B. When the colored pixel C is printed with a crossing angle shifted with respect to the photoelement A, the moiré phenomenon in which the enlarged image exhibits a sense of fluctuation when the appearance point is moved as an enlarged image having a stereoscopic effect when viewed from the surface. A decorative body with a point drawing pattern is disclosed.

Further, in Patent Document 1 described later, a plano-convex lens-shaped condensing element layer formed by arranging a large number of plano-convex lens-shaped condensing elements having the same shape and the same size vertically and horizontally, and the plano-convex lens-shaped condensing element layer Each of the above-mentioned plano-convex lens shapes, comprising a transparent substrate layer laminated below and a pixel layer formed by aligning a number of pixels of the same shape and size laminated below the transparent substrate layer vertically and horizontally. The light condensing element and each pixel at least one set overlaps the upper and lower sides completely, and another pixel equidistant from the overlapping pixel is a plano-convex lens condensing element corresponding to the other pixel. Thus, the plano-convex lens-shaped collection is arranged so that the pixels shifted radially outward (or inward) with the same width from the center of the overlapping pixels and shifted toward the outer pixels from the center pixel become larger. The photoelement layer and the pixel layer are arranged Virtual image displaying decorative body to emerge above the plano-convex lens-like condenser arsenide layer around the pixel enlarged virtual image of the same shape of the pixels overlap the (or lower) is disclosed.
Japanese Patent Laid-Open No. 10-35083 JP-A-2001-55000

  However, in the decorative body disclosed in the above-mentioned patent documents, a clear image cannot be produced unless a transparent layer having a certain thickness is laminated between the pixel layer and the plano-convex lens layer. As a result, it cannot be used for articles with a limited thickness such as a packaging box, and the decoration object is limited. Moreover, since the unevenness of the plano-convex lens appears on the surface, the surface treatment was difficult. Furthermore, when considering the formation by printing, it is difficult to form a transparent layer that requires a certain thickness by printing. For this reason, if a transparent plate made of a synthetic resin or the like is used as the transparent layer, the transparent layer is flat with the pixel layer. It was necessary to print the convex lens layer on a separate surface of the transparent plate, which was troublesome to manufacture. In addition, some commercially available transparent plates have a hard coat treatment or adhesive treatment on one side, and printing cannot be performed on the surface subjected to the treatment, so printing on both sides of the transparent plate is possible. Necessary decorations disclosed in the above-mentioned patent documents could not be employed.

Therefore, the present invention can make a clear image appear even though it is thin enough to be applied to an article having a limited thickness, and even when considering formation by printing, As a technical issue, to obtain a decorative body that can be stacked by printing, the prototype and experiment were repeated, and as a result, a pixel layer formed by aligning multiple pixels and a pixel layer below In a decorative body having a plano-convex lens layer formed by aligning a plurality of positioned plano-convex spherical lenses (plano-convex lenses), each plano-convex lens constituting the plano-convex lens layer faces the pixel layer so that the plane side faces each other. If a reflective surface that reflects light incident from the flat side is formed on the spherical side of the convex lens, a clear image can be obtained while maintaining a thin laminated structure without laminating a transparent layer between the pixel layer and the plano-convex lens layer. Present Obtained a finding should Katsumoku that can be, is obtained by achieving the technical problems.

  The technical problem can be solved by the present invention as follows.

That is, the decorative body according to the present invention includes a pixel layer formed by aligning a plurality of pixels and a plano-convex spherical lens layer formed by aligning a plurality of plano-convex spherical lenses positioned under the pixel layer, Each plano-convex spherical lens constituting the plano-convex spherical lens layer faces the plane side with respect to the pixel layer, and each plano-convex spherical lens has a reflecting surface that reflects light incident from the plane side on the spherical side , The pixels constituting the pixel layer and the plano-convex spherical lens constituting the plano-convex spherical lens layer are arranged in the same arrangement, and the arrangement of the pixels constituting the pixel layer and the plano-convex spherical lens constituting the plano-convex spherical lens layer The pixel is formed by concentrating the light reflected by the reflective layer by the plano-convex spherical lens, which is positioned so as to intersect with the lens arrangement and can be seen through the pixel when viewed from the plane side of the plano-convex spherical lens. An image consisting of a collection of A.

Further, the present invention, prior KiSo Kazaritai, those reflective surface is a reflective layer laminated on the spherical surface of the planoconvex spherical lens.

Further, the present invention, prior KiSo Kazaritai, those reflective surface is a reflective layer positioned under planoconvex spherical lens layer.

  According to the present invention, in any one of the decorative bodies, the pixel layer and the plano-convex spherical lens layer are laminated below the transparent layer.

  According to the present invention, the plane of the plano-convex lens constituting the plano-convex lens layer under the pixel layer is positioned with the plane facing the pixel layer side, and the reflection that reflects the light incident from the plane side of the plano-convex lens under the plano-convex lens layer Because the surface is formed, when the decorative body is irradiated with light, the light is reflected by the reflective layer, and the reflected light is condensed and shined by the plano-convex lens with a small overlap with the pixels. Therefore, the image formed by the aggregate of pixels that largely overlap with the plano-convex lens and blocks the incidence of light on the plano-convex lens positioned below is emphasized, and the image appears substantially on the decorative body. By adopting a spherical lens as the plano-convex lens, an image having a shape due to the shape of the pixel can be displayed. By adopting the laminated structure, it is not always necessary to laminate a transparent layer between the pixel and the plano-convex lens layer, and a clear image can be displayed. Even if a transparent layer is laminated, it is transparent. Since the thickness of the layer is not particularly limited, a clear image can be displayed even if a transparent layer having an arbitrary thickness is laminated. Further, since the surface of the decorative body is formed smoothly, surface treatment such as hard coat treatment can be easily performed. Furthermore, when considering the formation by printing, when laminating the pixel layer, the plano-convex lens layer, and the reflective layer on the transparent substrate (transparent layer), all the layers are sequentially stacked on one side of the transparent substrate. Since they may be laminated, the present invention can be applied to a commercially available transparent substrate that has been subjected to a hard coat treatment or an adhesive treatment on one side, and the object of decoration is greatly expanded.

  Therefore, it can be said that the industrial applicability of the present invention is very high.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  At this time, when the decorative body 1 is viewed from the X direction, a pair of pixel columns 17 whose positional relationship between the pixel 3 and the plano-convex lens 5 is equidistant from the reference pixel column 10 corresponds to the pixel column 17. 18 is shifted inward with respect to the reference pixel column 10 as a center, and the width shifted by the pixel column 17 outside the reference pixel column 10 is larger, so that the image is decorated with the reference pixel 8 as the center. It seems to sink in the back (downward).

  On the other hand, when the decorative body 1 is viewed from the Y direction, a pair of pixel rows 20 whose positional relationship between the pixels 3 and the planoconvex lens 5 is equidistant from the reference pixel row 19 corresponds to the pixel row 20. Is shifted inward with respect to the reference pixel row 19 and the width shifted by the pixel row 20 outside the reference pixel row 19 is increased. On the other hand, it appears to sink in the back (downward).

  Since the difference in the vertical pitch between the pixel 3 and the plano-convex lens 5 is smaller than the difference in the horizontal pitch between the pixel 3 and the plano-convex lens 5, an image having a shape stretched along the pixel row 17 appears. Further, as shown in FIGS. 18A and 18B, an image 33 that appears when the decorative body 1 is viewed from the Y direction rather than an image 32 that appears when the decorative body 1 is viewed from the X direction. Appears to sink to the upper height.

  Therefore, by rotating the decorative body 1 by 90 degrees, the images 32 and 33 appearing after sinking at different height positions can be visually recognized.

Yes.

  Next, the positional relationship between the pixel 3 and the plano-convex lens 5 will be described.

  The pixel layer 4 and the plano-convex lens layer 6 are one pixel row (pixel row located at the left end in FIG. 19) 34 in the pixel layer 4 and one plano-convex lens row in the plano-convex lens layer 6 (at the left end in FIG. 19). The plano-convex lens row 36 is parallel to each other, and the pixel 3 and the plano-convex lens 5 are stacked so as to have a pair of the reference pixel 8 and the reference plano-convex lens 9 that overlap most vertically. Then, the pixels 3 corresponding to the plano-convex lens 5 that are equidistant on the diagonal line with the reference plano-convex lens 9 as the center are laterally shifted symmetrically with respect to the plano-convex lens 5 about the reference plano-convex lens 9 and radially outward. The width is shifted toward the other pixel 3 outside the reference pixel 8 and is larger.

  Next, an image appearing on the decorative body 1 will be described.

  First, when light is irradiated from above the decorative body 1, the planoconvex lens 5 having a small overlap with the pixel 3 collects the light reflected by the reflective layer 7 and shines, as in the first embodiment. The image formed by the pixels 3 having a large overlap with 5 is emphasized, and the image appears on the decorative body 1.

  At this time, the pixels 3 corresponding to the plano-convex lens 5 that are equidistant on the diagonal line centered on the reference plano-convex lens 9 are laterally shifted symmetrically with respect to the plano-convex lens 5 about the reference plano-convex lens 9, and radially outward. Since the width of the other pixel 3 outside the reference pixel 8 is larger than the reference pixel 8, the image appears to float forward (upward) with respect to the decorative body 1 with the reference pixel 8 as the center. .

  Since the pixels 3 corresponding to the plano-convex lens 5 that are equidistant from the reference plano-convex lens 9 are not overlapped to the same extent, an image having a shape obtained by enlarging and deforming the shape of the pixel 3 appears.
