Description

  The present invention is a decoration applied to decoration of various products such as business cards, photo frames, outer panels of game machines and game machines, packaging boxes, advertising bodies, ornaments, display devices, stationery, souvenirs, structures, teaching materials, etc. This relates to the display body.

  Traditionally, it has been used as a decoration for various products such as business cards, photo frames, outer panels of game machines and game machines, packaging boxes, advertising bodies, ornaments, display devices, stationery, souvenirs, structures, teaching materials, etc. It is known to apply a decorative display body that makes an enlarged virtual image of a pixel appear from the surface of various products (for example, see Patent Documents 1 to 5 below).

  The decorative display bodies disclosed therein are two-dimensionally arranged at a predetermined arrangement pitch by providing a plurality of convex lens-shaped light condensing elements on the surface of a sheet-like or plate-like transparent material with the directionality of each light condensing element. The light condensing element pattern is formed by arranging the plurality of pixels on the back surface of the transparent material with the same directionality as the light condensing element pattern of each pixel and at a different arrangement pitch from each light condensing element. By forming a pixel pattern in a two-dimensional arrangement, an enlarged virtual image of the pixel appears above or below the transparent material.

  However, recently, decorative display bodies have been widely applied to various products and become familiar to general consumers, so that an enlarged virtual image of a pixel has a new visual effect. . In this regard, all of the conventional decorative display bodies only allow the enlarged virtual image to be viewed in a static state without being limited by the viewing position.

  The present invention has been made in view of the above-described technical background, and an object thereof is to provide a decorative display body capable of visually recognizing an enlarged virtual image in a dynamic state.

  In order to achieve the above object, the present invention provides a plurality of convex lens-shaped light condensing elements on the surface side of a sheet-like or plate-like transparent material with a predetermined arrangement pitch with the directivity of each light condensing element. The light condensing element pattern is formed by two-dimensionally arranging the plurality of pixels on the back surface side of the transparent material with the same directionality as the light condensing element pattern of each pixel. A reference point is set on the back side of a transparent material in a decorative display that displays an enlarged virtual image of the pixel above or below the transparent material by forming a pixel pattern in a two-dimensional array at different arrangement pitches. The pixel pattern is formed such that the pixel diameter gradually increases toward the reference point.

  According to this, as the pixel diameter of each pixel gradually increases toward the reference point, the enlarged virtual image of each pixel that appears by the light condensing element also gradually increases toward the reference point. For this reason, at the position close to the reference point, the peripheral portions of the enlarged virtual images of adjacent pixels overlap and merge with each other, and the degree of the overlap gradually increases toward the reference point. The overall shape also changes gradually. When the direction in which the decoration display body is viewed is changed using this fact, the entire shape of the enlarged virtual image gradually changes, so that the enlarged virtual image can be viewed in a dynamic state.

  Further, it is preferable that a pixel pattern region having a predetermined shape is provided on the back side of the transparent material, and the pixel pattern is disposed in the pixel pattern region. According to this, the enlarged virtual image can be visually recognized in the pixel pattern region.

  Moreover, it is preferable that a plurality of pixel pattern regions having a predetermined shape are provided on the back side of the transparent material. According to this, a plurality of enlarged virtual images can be visually recognized simultaneously in a dynamic state.

  The pixel pattern regions are preferably arranged in a grid pattern in the plane direction on the back side of the transparent material. According to this, since the enlarged virtual image visually recognized in a dynamic state is regularly arranged, it is possible to improve the overall design as a decorative display body.

  The pixel pattern region is preferably formed with a size within a range of 50 mm. According to this, one enlarged virtual image appears in the vicinity of the reference point in the pixel pattern region, and dynamically changes so that the outline of the enlarged virtual image gradually changes as the direction of viewing the decorative display body is changed. It can be visually recognized.

  According to the present invention, as the pixel diameter of each pixel gradually increases toward the reference point, the enlarged virtual image of each pixel that appears by the light condensing element also gradually increases toward the reference point. For this reason, at the position close to the reference point, the peripheral portions of the enlarged virtual images of adjacent pixels overlap and merge with each other, and the degree of the overlap gradually increases toward the reference point. The overall shape also changes gradually. When the viewing direction of the decoration display body is changed by utilizing this, the entire shape of the enlarged virtual image gradually changes, so that the enlarged virtual image can be visually recognized in a dynamic state, and thus a new decoration effect is achieved. It becomes possible.

  Next, an embodiment of a decorative display body according to the present invention will be described with reference to FIGS.

  As shown in FIGS. 1 and 2, the decorative display body 1 according to the present embodiment includes a transparent material 10 made of a synthetic resin such as an acrylic plate, and a light collecting element made of a light collecting element 11 a on the surface of the transparent material 10. An elementary pattern 11 is formed, and pixel patterns 12 and 12 ′ including a plurality of pixels 12 a and 12 a ′ are formed on the back surface of the transparent material 10. The transparent material 10 used here is a plate-like member that is formed in a square shape in plan view and has a thickness d of 2.0 mm.

  As shown in FIG. 1, the light condensing element pattern 11 is formed by directly printing a plurality of convex lens-shaped light condensing elements 11a on the surface of the transparent material 10 using a colorless and transparent ink such as an ultraviolet curable resin. It has been done. As shown in FIG. 4, the light condensing element pattern 11 is formed by two-dimensionally arranging the light condensing elements 11a in the same direction as the light condensing elements 11a. The light condensing elements 21 are regularly arranged in a matrix with the same arrangement pitch p in the x direction inclined by 45 degrees clockwise and the y direction orthogonal thereto.

  In this embodiment, the diameter of each light condensing element 11a is set to 0.6 mm, and the arrangement pitch p is set to 0.7 mm. Further, the arrangement of the light condensing elements 11a is not necessarily an orthogonal pattern, and the other arrangement direction with respect to one arrangement direction may form an angle smaller than 90 degrees or an angle larger than 90 degrees.

  As shown in FIG. 2, the pixel patterns are respectively arranged in a plurality of pixel pattern regions having a predetermined shape provided on the back surface of the transparent material 10. These pixel pattern areas have a first pixel pattern area S1 having a rectangular shape (square in the present embodiment) with a first color (for example, white) as a background and a second color (for example, black) as a background. And a second pixel pattern region S2 having a rectangular shape (square in this embodiment) in plan view. The first pixel pattern 12 is disposed in the first pixel pattern region S1, and the second pixel pattern 12 ′ is disposed in the second pixel pattern region S2. The pixel pattern regions S1, S2 Are arranged in a grid pattern in the plane direction in an alternating manner in the vertical direction and the horizontal direction.

  As shown in FIG. 3A, the overall shape of the first pixel pattern 12 is circular inside the first pixel pattern region S1. As shown in FIG. 4, this first pixel pattern 12 is directly arranged by two-dimensionally arranging a plurality of black pixels 12a in the same direction as the light condensing element pattern 11 of each pixel 12a. It is formed by printing. That is, the first pixel pattern 12 is formed by equally arranging the pixels 12a in a matrix in one direction and a direction orthogonal thereto, and the arrangement direction of the pixels 12a is the arrangement direction of the light condensing element pattern 11. It is formed in a manner that matches the x direction and the y direction.

  In the first pixel pattern 12, as shown in FIG. 4, the pixels 12a are arranged at an arrangement pitch q larger than the arrangement pitch p of the light condensing elements 11a. In this embodiment, the arrangement pitch q of the pixels 12a is arranged. Is set to 0.71 mm. As a result, in the light condensing element pattern 11 and the first pixel pattern 12, in a plan view, every portion where the light condensing elements 11a and the pixels 12a completely overlap with each other, and the surrounding pixels 12a sequentially from the light condensing element 11a. A portion that is displaced outwardly is generated.

  Further, as shown in FIG. 3A, the first pixel pattern 12 is such that the pixel diameter L of each pixel 12 a gradually increases from the peripheral edge of the first pixel pattern 12 toward the reference point 13. As a result, the density of the pixels 12 a gradually increases from the peripheral edge of the first pixel pattern 12 toward the reference point 13. The reference point 13 is virtually set inside the pixel pattern region S1 where the first pixel pattern 12 is formed. In the present embodiment, the reference point 13 is set at the center of the pixel pattern region S1. .

  Specifically, as shown in FIG. 4A, the pixel diameter L of the pixel 12a on the outer side (right side of FIG. 4A) is sequentially shifted toward the reference point 13 (left side of FIG. 4A). Assuming L1, L2, L3, L4, and L5, the pixel diameter L of the pixel 12a gradually increases as the distance from the reference point 13 becomes L1 <L2 <L3 <L4 <L5. Therefore, the pixel pattern 12 is formed in such a manner that adjacent pixels 12 a are separated from each other at a position far from the reference point 13, and adjacent pixels 12 a are overlapped at a position close to the reference point 13.

  On the other hand, the second pixel pattern 12 'has basically the same configuration as the first pixel pattern 12 described above except that the background color and the color of the pixel 12' are different. That is, the second pixel pattern 12 ′ has a circular shape inside the second pixel pattern region S2 as shown in FIG. 3B, and a plurality of white patterns as shown in FIG. The pixels 12a ′ are two-dimensionally arranged at an arrangement pitch q with the same directionality as the light condensing element pattern 11 of each pixel 12a ′, and are formed by direct printing.

  Further, as shown in FIGS. 3B and 4, the second pixel pattern 12 ′ has a pixel diameter L of the pixel 12a ′ toward the reference point 13 provided at the center of the second pixel pattern region S2. It is formed so as to increase gradually.

  In the present embodiment, the arrangement pitch p of the light condensing elements 11a is set to 0.7 mm, whereas the arrangement pitch q of the pixels 12a and 12a ′ is set to 0.71 mm. This is because when 10 has a thickness of 2.0 mm, the value satisfies the condition for clearly displaying the enlarged virtual image Z of the pixels 12a and 12a ′.

  According to the above, the light condensing element pattern 11 is formed on the front surface of the transparent material 10, the first pixel pattern 12 is disposed in the first pixel pattern region S1 provided on the back surface of the transparent material 10, and the first The second pixel pattern 12 ′ is arranged in the second pixel pattern region S2. Therefore, as shown in FIG. 5, the enlarged virtual image Z of the pixel 12 a and the enlarged virtual image Z ′ of the pixel 12 a ′ can appear above the transparent material 10.

  Here, paying attention to the appearance of the enlarged virtual image Z1 by the first pixel pattern 12, as shown in FIG. 3A, the first pixel pattern 12 has a pixel diameter L of the pixel 12a toward the reference point 13. As a result, the enlarged virtual image Z of each pixel 12 a that appears by the light condensing element 11 a gradually increases toward the reference point 13. For this reason, at the position close to the reference point 13, the peripheral portions of the enlarged virtual images Z of the adjacent pixels 12a are overlapped and merged, and the degree of overlap gradually increases toward the reference point 13, Along with this, the overall shape of the enlarged virtual image Z of the pixel 12a gradually changes.

  This will be specifically described with reference to FIG. 6. Since the pixel diameter L of the pixel 12 a is small at a position far from the reference point 13 as shown in FIG. 6A, the enlarged virtual image Z of the adjacent pixel 12 a is Appears in a single, independent state. At the position approaching the reference point 13, as shown in FIG. 6B, the pixel diameter L of the pixel 12 a is large, so that the peripheral portions of the enlarged virtual images Z of the adjacent pixels 12 a overlap and merge. Appears in a state of being. Further, at a position closer to the reference point 13, as shown in FIG. 6C, the pixel diameter L of the pixel 12a is larger, so that the peripheral portions of the enlarged virtual images Z of the adjacent pixels 12a overlap. And the overall shape of the enlarged virtual image Z of the pixel 12a changes. Thus, the entire shape of the enlarged virtual image Z of the pixel 12a appearing by the light condensing element 11a can be gradually changed toward the reference point 13. Although the enlarged virtual image Z of the pixel 12a illustrated in FIG. 6 has a clear outline, the actual enlarged virtual image Z is visually recognized with the outline blurred, and the enlarged virtual image Z of the pixel 12a Even in a state where the peripheral portions are united, the contour is visually blurred.

  In the above description, the appearance of the enlarged virtual image Z by the first pixel pattern 12 has been described. However, the mechanism is the same for the appearance of the enlarged virtual image Z ′ of the pixel 12a ′ in the second pixel pattern 12 ′. Therefore, the description is omitted.

  Utilizing the above, the position of viewing the decoration display 1 is changed, and the peripheral portions of the enlarged virtual image Z of the adjacent pixels 12a and the peripheral portions of the enlarged virtual image Z ′ of the adjacent pixels 12a ′ are overlapped. The combined virtual image Z of the pixels 12a and 12a ′ is changed by changing the overall shape of the enlarged virtual images Z and Z ′ of the pixels 12a and 12a ′ by changing the overlapping degree. , Z ′ can be visually recognized in a dynamic state.

  This will be described below with reference to FIG. In FIG. 7A, the direction of viewing the decoration display body 1 is indicated by arrows A1 to A3. 7B is a decorative display when viewed from the direction of arrow A1, FIG. 7C is viewed from the direction of arrow A2, and FIG. 7D is a decorative display when viewed from the direction of arrow A3. Shows the enlarged virtual image that appears. Further, in FIGS. 7B to 7D, a plurality of pixel pattern areas arranged in 3 rows × 3 columns, the first pixel pattern area S1 is arranged in the center, and the first pixel pattern area S1 is used as a reference. The pixel pattern region S1 and the second pixel pattern region S2 are arranged in a grid pattern in the plane direction so as to be alternated.

  As shown in FIGS. 7B to 7D, the enlarged virtual images Z11, 12, 13, 21, 22, 23, 31, appearing in the first pixel pattern region S1 and the second pixel pattern region S2, respectively. As for 32 and 33, the whole shape is changing by changing directions A1-A3 which look at this decoration display body 1, respectively. This appears in the state where the enlarged virtual images Z and Z ′ of the pixels 12a and 12a ′ adjacent to each other toward the reference point 13 are overlapped and merged, and the peripheral portion of the enlarged virtual image Z of the adjacent pixels 12a. Since the degree of overlap between each other is large, the overall shape of the magnified virtual images Z and Z ′ appearing by the light condensing element 11a is dynamically recognized so as to gradually change as the viewing direction changes. It is thought that.

  Here, only the three viewing directions indicated by arrows A1 to A3 have been described. However, when the viewing direction is continuously changed, the overall shapes of the enlarged virtual images Z and Z ′ of the pixels 12a and 12a ′ are gradually and continuously increased. It can be visually recognized as if it changes.

  In the decorative display body 1, since the pixel patterns 12, 12 ′ are arranged in the pixel pattern areas S1, S2, the enlarged virtual images Z of the pixels 12a, 12a ′ are floated in the pixel pattern areas S1, S2. It can be made to visually recognize as if.

  In addition, since a plurality of pixel pattern areas (pixel pattern areas S1, S2) are provided, a plurality of enlarged virtual images Z, Z 'can be visually recognized simultaneously in a dynamic state.

  In addition, since the plurality of pixel pattern areas S1 and S2 are arranged in a lattice pattern, the enlarged virtual images Z and Z ′ that are visually recognized in a dynamic state are regularly arranged. Overall design can be improved.

  Further, by forming the pixel pattern area with a size within the range of 20 mm, only one enlarged virtual image 12, 12 'appears in the vicinity of the reference point 13 in the pixel pattern areas S1, S2. And it can be made to visually recognize so that the outline of this expansion virtual image Z and Z 'changes gradually as the direction which sees this decoration display body 1 is changed.

  For reference, it can be seen that referring to the photograph of one product of the decorative display according to the present invention shown in FIG. 8, it can be seen from this photograph that the entire shape of the enlarged virtual image of the pixel changes.

  In addition, although this embodiment demonstrated the case where the thickness of the transparent raw material 10 was 2.0 mm, other thickness may be sufficient and a thin sheet form may be sufficient.

  Moreover, although the case where the arrangement pitch q of the pixels 12a and 12a 'is larger than the arrangement pitch p of the light condensing elements 11a has been described, it may be smaller than the arrangement pitch p. In this case, the enlarged virtual images Z and Z ′ of the pixels 12 a and 12 a ′ appear on the back side (the lower side in FIG. 5) of the transparent material 10.

  Moreover, although the case where the reference point 13 is set at the center of the first pixel pattern region S1 and the second pixel pattern region S2 has been described, it may be other than the center in each of the regions S1 and S2.

  In addition, the pixel pattern region S1 and the second pixel pattern region S2 have been described as being arranged in a lattice shape. However, the pixel pattern region S1 and the second pixel pattern region S2 do not necessarily have to be regularly arranged as in a lattice shape, and may be arranged at arbitrary positions. Also good.

  Moreover, although the case where two types of pixel pattern regions are provided, the pixel pattern region S1 and the second pixel pattern region S2, has been described, one or more types may be used.

  Moreover, although the case where a plurality of pixel pattern regions are provided has been described, one pixel pattern region may be provided.

  Further, although the case where the pixel pattern region is rectangular has been described, other shapes may be used.

  Moreover, although the size of the pixel pattern region is set to 20 mm on a side, it may be formed in other sizes. However, in order to dynamically recognize one enlarged virtual image in one pixel pattern region, it is necessary to set the size of the pixel pattern region within a range of 50 mm.

  Further, the case where the arrangement pitch p of the light condensing elements 11a and the arrangement pitch q of the pixels 12a and 12a ′ are constant has been described, but either one or both of the arrangement pitch p and the arrangement pitch q change. Also good.

  Further, the case where the light condensing element 11a and the pixels 12a and 12a 'are circular has been described, but other shapes may be used.

  In addition, the case where the shape of the pixels 12a and 12a ′ does not change is described except that the pixel diameters of the pixels 12a and 12a ′ are not changed. However, the pixels 12a and 12a ′ are changed depending on the outline, color, and other elements. Also good.

  Further, although the light condensing element pattern 11 is formed by printing directly on the front surface of the transparent material 10 and the pixel patterns 12 and 12 'are respectively printed on the back surface of the transparent material 10, they are formed by other methods. It may be a thing.

  For example, a transparent sheet-like or plate-like member in which a light condensing element pattern is previously formed on the surface side of a transparent material is provided, and a sheet-like or plate-like member in which a pixel pattern is previously formed on the back side of the transparent material. It may be provided to constitute a decorative display body. In addition, a condensing element pattern and a pixel pattern are provided on the surface side of one transparent material, and the transparent element is folded into two or more so that the condensing element pattern and the pixel pattern are opposed to each other through the transparent material. You may make up your body.

  Moreover, although the case where the pixel 12 is black and the pixel 12 'is white has been described, other colors may be used.

  In addition, the reference point 13 is preferably set at the central portion of the pixel pattern region S1, but may not necessarily be set at the central portion. In short, it is sufficient that each pixel of the first pixel pattern 12 is formed so as to gradually increase toward the reference point 13 set in the pixel pattern region S1.

  As mentioned above, although embodiment of this invention was described with reference to drawings, this invention is not limited to the thing of embodiment shown in figure. Various modifications and variations can be made to the illustrated embodiment within the same range or equivalent range as the present invention.
