In addition, there is an image forming body in which glossy ink is formed in a convex shape and light reflection is used to make it possible to visually recognize different images depending on the viewing angle.

  The technology using these parallax barriers and lenticular lenses allows a pattern formed with ink to be viewed three-dimensionally with a lens having a considerable thickness, etc. Or, on the line with color flip-flop characteristics, the image inside the frame divided from the base image is compressed in a predetermined direction, and the latent image elements with different shapes are regularly raised without overlapping. By disposing it on the line that it has, the base image can be dynamically visually recognized when the observation angle is continuously changed without using a discriminating tool and without having the thickness of a parallax barrier or lenticular lens. An image print product has been filed (for example, see Patent Document 1).

  In addition, the present applicant regularly arranges a plurality of convex image lines with high gloss ink, divides the convex image lines into n or more, and provides a step in the divided area to at least two. Two low-gloss latent image lines are formed, and the latent image lines are arranged in parallel at the same pitch as the convex image lines, so that at least two latent image images are formed. A difference in reflectance occurs between the surface layer of the convex image line and the low-gloss latent image line, so that one latent image can be visually recognized, and at least two latent image images are switched and viewed according to changes in the angle of incident light. An application has been filed for a latent image print using a possible gloss difference (see, for example, Patent Document 2).

  DESCRIPTION OF EMBODIMENTS Embodiments for carrying out the present invention will be described with reference to the drawings. However, the present invention is not limited to the embodiments described below, and includes various other embodiments within the scope of the technical idea described in the scope of claims.

  In FIG. 1, the gift certificate of the three-dimensional display formation body (henceforth "formation body") (1) in this invention is shown. As shown in FIG. 1, the formed body (1) has a glossy image forming area (3) in at least a part of the substrate (2), and the image forming area (3) At least a stereoscopic display image (4) is formed.

  Although the details of the stereoscopic display image (4) will be described later, since the base (2) is formed in a concave shape or a convex shape, the concave shape or the convex shape of the base material (2) is displayed. If the image (4) can be formed, it can be paper, plastic, metal or the like. However, as described above, the image forming region (3) where the stereoscopic display image (4) is formed needs to have gloss. Therefore, the base material (2) itself may be a glossy material, or only the image forming region (3) may be glossy.

  In order for the whole substrate (2) to have a gloss, the substrate (2) itself is made of a glossy metal material (for example, a metal deposition film such as aluminum in the security field) or a plastic (for example, a card substrate). Polyvinyl chloride, PETG, polycarbonate, etc.) can be used. In addition, for paper or plastic that originally has no gloss, the surface of the substrate (2) may be given gloss by printing or coating. For example, pearl ink can be printed.

  Further, to give gloss only to a part of the image forming region (3) of the substrate (2), as described above, a glittering material such as pearl ink can be applied by printing or the like. In the formed body (1) shown in FIG. 1, glossiness is imparted with pearl ink only in a part of the image forming region (3) of the paper base (2).

(First embodiment)
FIG. 2 shows an enlarged view of the first stereoscopic display image (4) of the first embodiment in the stereoscopic display formation of the present invention. The first stereoscopic display image (4) is a first stereoscopic display image group in which a plurality of first stereoscopic display images (6) that form the first original image (5) to appear are regularly arranged. (7). As shown in FIG. 2A, the first stereoscopic display image (4) has a first stereoscopic display image line (6) formed in a convex shape with respect to the base material (2). In the case where it is configured by a plurality of first stereoscopic display image groups (7) regularly arranged in the direction (S1), as shown in FIG. 2 (b), the substrate (2) is recessed. When the first 3D display image line (6 ′) formed in the shape is composed of a first 3D display image group (7 ′) regularly arranged in the first direction (S1). In either case, the effects of the present invention are achieved. In the present invention, the fact that a plurality of lines are regularly arranged in the same direction and at the same pitch is hereinafter referred to as “arranged in a line”.

  The image forming area (3) is divided into a first pattern portion (20) where the first stereoscopic display image line group (7) is formed and a first background portion (21) other than that. Yes.

  The first stereoscopic display image group (7 and 7 ') will be described in detail. First, the first stereoscopic display image line group (7) formed in the convex shape shown in FIG.

  FIG. 3A is a plan view schematically showing a first stereoscopic display image (4) formed using the first stereoscopic display image line group (7) formed in a convex shape and its plan view. It is XX 'sectional drawing in the inside. As shown in the cross-sectional view of FIG. 3A, the first stereoscopic display image line (6) has a convex shape with respect to the base material (2) and a part of which is missing. Further, FIG. 3B shows an enlarged cross-sectional view of a portion surrounded by a dotted line. As shown in FIG. 3B, the first stereoscopic display image line (6) has a bowl shape in which the surface of the image line has a curved surface. Details of the first stereoscopic display image line (6) will be described in detail in the description of the manufacturing method, but the image lines in the first stereoscopic display image group (7) are all different shapes. Adjacent lines are the most approximate shapes. Although details will be described later, FIG. 3 illustrates a state in which the stereoscopic display image group (7) is formed by printing on the base material (2). Alternatively, an embossed plate (9) for processing the shape of the substrate (2) may be used.

  What is most important in the present invention is that the surface shape of the first stereoscopic display image is a bowl-shaped curved surface, regardless of the convex shape described above or the concave shape described later. . With this curved surface, the light is reflected around the surface of the image line that is normal to the incident light with respect to the incident light. In other words, depending on the angle of the incident light, the first stereoscopic display image line ( Of the surface of 6), the region that strongly reflects light changes. Therefore, as an effect of the present invention, in order for an image to be visually perceived three-dimensionally and dynamically, the reflected light needs to move smoothly. It becomes a change of light.

  In the technique described in Patent Document 2 described above, a step is provided for a convex image line. By providing this step, the surface of the image line does not become a curved surface, and the image can be changed. However, it is not possible to produce an effect that allows the image to move smoothly and be visually recognized. This point is a big difference between a technique for changing an image and a technique for producing a dynamic effect even if a part of the same convex or concave image line has a step.

  As described with reference to FIG. 2, the first stereoscopic display image (4) may be a convex line, but can also be formed as a concave line. Will be described.

  FIG. 4A is a plan view schematically showing a first stereoscopic display image (4) formed using the first stereoscopic display image group (7 ′) formed in a concave shape and its plane. It is XX 'sectional drawing in a figure. As shown in the cross-sectional view of FIG. 4A, the first stereoscopic display image line (6 ') has a concave shape with respect to the base material (2) and a part thereof is missing. Further, FIG. 4B shows an enlarged cross-sectional view of a portion surrounded by a dotted line. As shown in FIG. 4B, the first stereoscopic display image line (6 ') has a bowl shape in which the surface of the image line corresponding to the bottom surface of the recess has a curved surface. This is the reverse of the so-called convex first stereoscopic display image (6) described above. Also in the first stereoscopic display image line group (7 '), all the image lines have different shapes, and adjacent image lines have the most approximate shapes.

  Also for the concave three-dimensional display image line (6 ′), the surface of the image line (the bottom surface of the concave portion) needs to have a bowl-shaped curved surface. Since the formation of 4) is the same as the convex three-dimensional display image line (6) described above, the description thereof is omitted.

  The first stereoscopic display image line (6 ′) in FIG. 4 and the first stereoscopic display image line (6) in FIG. 3 will be described in detail when the production method is described. Since the lines (6, 6 ′) are formed by embossing, the shape of the embossed plate (9) for that is reversed in the case of the first three-dimensional display image line (6) of FIG. In the case of the first stereoscopic display image line (6 ′) in FIG. 4, the shape is as shown in FIG. 3, and the so-called negative / positive relationship is established.

  As described above, the first stereoscopic display image line (6, 6 ′) constituting the first stereoscopic display image group (7, 7 ′) is concave or convex with respect to the base material (2). It is formed into a shape. Although a specific production method and the like will be described later, any shape is formed by pressing the substrate (2) using the embossed plate (9). The embossed plate (9) can be produced by laser processing using image data obtained by producing the stereoscopic display image group (7, 7 ') to be formed. In addition, an embossed plate (9) may be produced by printing image data on a photosensitive resin plate, and the first three-dimensional display image group (7, 7 ') can be formed in an uneven state. If so, there is no particular limitation on the method for producing the embossed plate (9).

  Regarding the height of the image line when the first stereoscopic display image line (6, 6 ') is a convex shape and the depth of the image line when it is a concave shape, it depends on the thickness and material of the base material (2). Although it is different, it is preferable to form in the range of 2-100 micrometers with respect to a base material (2). When the height or depth of the image line is less than 2 μm, the difference between the reflected light with respect to the incident light from the light source (Q) and the reflected light with respect to the base material (2) disappears, and the first solid Since it cannot be recognized as the display image line (6, 6 '), the desired three-dimensional and dynamic effects cannot be achieved. In addition, when the height or depth of the image line is larger than 100 μm, there is no problem in producing a visual effect. However, if it is considered to be added to the product as an anti-counterfeiting element, it is manufactured. Since it is not suitable for ease and form, it is not preferable.

  In order to produce an effect that the first stereoscopic display image (4) of the present invention can be viewed stereoscopically and dynamically, the first stereoscopic display image line (6) described above has a curved surface with a bowl-like surface. It is necessary to have glossiness. Therefore, the first three-dimensional display image line (6) and a saddle-shaped image line (8) described later are formed by an image line having glitter. The glitter in the present invention means light / dark flip-flop and / or color flip-flop, and the saddle-shaped image line (8) has the characteristics of light / dark flip and / or color flip-flop. Become.

  Brightness / darkness flip-flop property means that brightness changes due to a change in observation angle, and color flip-flop property means that hue changes due to a change in observation angle. In the present invention, a stereoscopically and dynamically viewed image includes a portion that regularly reflects incident light with respect to an image line having a bowl-shaped curved surface. Since the contrast between the specularly reflected incident light and the diffusely reflected incident light is large, it becomes possible to make a three-dimensional and dynamic image with the naked eye. Therefore, the 3D display image (6) or the bowl-shaped image (8) having a curved surface has a characteristic of light / dark flip property and / or color flip-flop property, which is a material having a predetermined amount of reflected light with respect to the light source. It is necessary to have.

  Examples of materials having light / dark flip properties and / or color flip flop properties include common metal pigments such as aluminum powder, copper powder, zinc powder, tin powder, brass powder or iron phosphide, iris pearl pigments and scales. Inks containing general pearl pigments such as pigments, transparent inks, and gloss-based inks can be used. These inks are printed or applied on at least the entire image forming area (3) on a general paper base material, and a concave or convex three-dimensional display image (6) or a bowl-like shape by embossing or the like as will be described later. An image line (8) may be formed.

  In addition, the material having the light / dark flip property and / or the color flip-flop property that can be used for the substrate (2) itself includes a general metal material such as aluminum or stainless steel, or a resin material such as a film or plastic. In addition, there is a base material (2) coated with pearl ink, a paint capable of forming a smooth surface, etc., but the three-dimensional display line (6) or the saddle-shaped line (8) has bright and dark flipping properties and / or Alternatively, a material to be formed is not limited as long as it has color flip-flop properties.

(Second embodiment)
Next, a second embodiment of the formed body of the present invention will be described. In the first embodiment described above, the first stereoscopic display image (6) itself is concave or convex, and the surface has a bowl-shaped curved surface. A first stereoscopic display image line (6) is formed on a part of the glittering moth-like image line (8), and the surface of the moth-like image line (8) has a curved surface, but the first three-dimensional image image is displayed. The image line (6) has a shape that reduces the glossiness by having a step from the bowl-shaped curved surface. This will be specifically described with reference to FIGS.

  In FIG. 5, ridge-like image lines (8) having glitter are arranged in a line in the image forming area (3). A first stereoscopic display image line (6) is formed on a part of the saddle-shaped image line (8). Since the first stereoscopic display image line (6) is the same as that of the first embodiment described above, the description thereof is omitted. The image forming area (3) includes a first pattern portion (20) including a plurality of bowl-shaped image lines (8) on which the first three-dimensional display image line (6) is formed, and a first three-dimensional display. It is divided into a first background portion (21) composed of a plurality of bowl-shaped image lines (8) in which the image line (6) is not formed. In addition, the 1st pattern part (20) in 2nd embodiment will be the same as the 1st three-dimensional display image line group (7) in 1st embodiment.

  FIGS. 5B and 5C are X-X ′ cross-sectional views in the plan view of the image forming region (3) shown in FIG. As shown in FIG. 5B, the first background portion (21) has a bowl shape in which the surface of the image line has a curved surface. Moreover, as shown in FIG.5 (c), the 1st pattern part (20) has the saddle-shaped image line (8) which has a level | step difference (lack) in a part of the saddle-shaped image line. . A portion where a part of the image line is stepped (missed) is where the first stereoscopic display image line (6) is formed.

  In the first stereoscopic display image line (6) of FIG. 3B in the first embodiment described above, it has been explained that the curved surface of the surface of the image line itself has a shape that exhibits the effects of the present invention. However, the first stereoscopic display image line (6) shown in FIG. 5C is a bowl-shaped image line (8) having a curved surface around the first stereoscopic display image line (6). The region that strongly reflects light is outside the image line, and the first stereoscopic display image line (6) is not glossy. Therefore, FIG. 3B and FIG. 5C have a negative-positive relationship. The first three-dimensional display image (4) can be confirmed three-dimensionally by the difference in glossiness between the first three-dimensional display image line (6) and the bowl-shaped image line (8), and dynamic by changing the observation angle. It will have a great effect.

  For example, the saddle-like image line (8) having a convex saddle-shaped curved surface shown in FIG. 5 (c) has the first stereoscopic display image line (6) having a step in a part thereof as the base material. Although it is formed with the same height as (2), it may be formed at a position higher than the base material (2) as shown in FIG. ), It is sufficient that a difference in gloss is generated. Therefore, in order to reduce the glossiness of the first 3D display image line (6), it may be in a jagged state. The first three-dimensional display image line (6) in FIG. 6B is formed in a jagged state at a position lower than the surface of the saddle-shaped image line (8). There is no limitation in particular about, For example, you may form in the position substantially equivalent to the curvature of the surface of a bowl-shaped image line (8). Anyway, the glossiness of the first stereoscopic display image line (6) should be lower than the glossiness of the surface of the bowl-shaped image line (8).

  Furthermore, in the first stereoscopic display image line (6 ′) shown in FIG. 6C, a step (convex portion) is provided in a part of the concave bowl-shaped image line (8 ′), and the step portion is This is the first stereoscopic display image line (6 ′). In the first stereoscopic display image line (6 ′) shown in FIG. 4 described above, it has been described that the curved surface on the surface of the image line itself has a shape that exerts the effect of the present invention. The first stereoscopic display image line (6 ′) shown in FIG. 6 is a bowl-shaped image line (8 ′) having a curved surface on the surface around the first stereoscopic display image line (6 ′). The reflective area is outside the image line, and the first stereoscopic display image line (6 ′) is not glossy. Therefore, FIG. 4B and FIG. 6C are in a negative / positive relationship.

  Regarding the first stereoscopic display image line (6 ′) of FIG. 6C, the first 3D display image line (6) of FIG. 3B and the convex shape of FIG. Similarly to the relationship with the first stereoscopic display image line (6 ′), the shape of the embossed plate (9) in the case of the first stereoscopic display image line (6) in FIG. The shape of the embossed plate (9) of the first three-dimensional display image line (6 ′) in FIG. 6 (c) becomes the shape as shown in FIG. 5 (c).

  As described above, the first stereoscopic display image group (7, 7 ') constituting the first stereoscopic display image (4) and the first stereoscopic display image group (7, 7') are further configured. The first three-dimensional display image line (6, 6 ′) and the saddle-shaped image line (8, 8 ′) have been briefly described. How these image lines are formed will be described below with reference to FIG. A block diagram relating to the production system of FIG. 8 and the production flowcharts of FIGS. The description will be given first using the convex stereoscopic display image line (6) shown in FIG.

  As shown in FIG. 7, the system (S) for producing the formed body (1) includes at least an input unit (101), a processing unit (102), and a processing unit (103), and the processing unit (102). ) May include a storage unit (104).

  Using the above-described system, first, the processing unit (102) creates or determines an original image (5) that is a basis of a pattern to be viewed three-dimensionally and dynamically (Step 1). The original image (5) is not particularly limited, and can be an arbitrary image such as characters, designs, and patterns.

  In addition, the original image (5) may be directly produced in the processing unit (102). The processing unit may be arbitrarily selected from a plurality of original images (5) stored in the storage unit (104) in advance. It may be determined in (102). In the present embodiment, as shown in FIG. 10, an example of an image of “Sakura no Hana” will be described as the original image (5).

  In addition to the creation or determination of the original image (5), the original image setting is performed until data corresponding to the original image (5) to appear under specular reflection light is input from the input unit (101). It becomes a process. The data here constitutes the first stereoscopic display image (4) such as the compression rate of the original image (5) described later, the line width and pitch of the first stereoscopic display image line (6), and the like. This is data necessary for the production of the first stereoscopic display image line group (7).

  Next, in the processing unit (102), a first stereoscopic display image group (7) is created from the original image (5) (Step 2). A specific method of producing the first stereoscopic display image line group (7) will be described below including FIG.

  As shown in FIG. 11, the first stereoscopic display image group (7) includes the first stereoscopic display image lines (6-1, 6) formed based on the pattern of “cherry blossoms” in the original image (5). −2,..., 6-n (n is a natural number equal to or greater than 2)) in a first direction (W1) with a constant first pitch (P1) and a constant stereoscopic display image line width (W1). S1) is regularly arranged. The first direction (S1) in the present invention is the S1 direction in the drawing and is a direction orthogonal to the first stereoscopic display image line (6).

  FIG. 12 shows the configuration of the first stereoscopic display image lines (6-1, 6-2,..., 6-n) forming the first stereoscopic display image group (7). Among the plurality of first stereoscopic display image lines (6), in the first 3D display image line group (7), the first 3D display image line (6-1) located on the leftmost side of the drawing, The first stereoscopic display image line (6-i) located at the center and the first stereoscopic display image line (6-n) located on the right side of the drawing will be extracted and described.

  The first stereoscopic display image line (6-1, 6-i, 6-n) is a frame (F-1, F-i, F-n) is applied to divide the original image (5), and the divided original image (5) is used as each intra-frame image (10-1, 10-i, 10-n). Extracted and formed by compressing the in-frame images (10-1, 10-i, 10-n) to the stereoscopic display image line width (W1). Note that the stereoscopic display image line width (W1) in the present invention includes the image line part of the pattern of “Sakura no Hana” as the original image (5) and the blank part to which the image line part is not added. This is the width formed by compressing the in-frame image (F).

  The height of the frame (F) applied to the original image (5) may be equal to or higher than the height of the original image (5), and the width (W2) of the frame shown in FIG. 12 is the width of the original image (5). Must be: Therefore, the first stereoscopic display image line (6-1) positioned at the left end of the first stereoscopic display image group (7) includes only the image of the left end portion of the original image (5), and the first The first stereoscopic display image line (6-i) located at substantially the center of the 3D display image line group (7) includes only the image of the central portion of the original image (5), and the first stereoscopic display image The first stereoscopic display image line (6-n) located at the right end of the image line group (7) includes only the image of the right part of the original image (5).

  As for the method of creating the first stereoscopic display image group (7), as shown in FIG. 9, first, the position of the leftmost frame (F-1) serving as a reference for all frame positions is determined (Step 2). -1). The position of the leftmost frame (F-1) serving as a reference is a position where the right side of the frame (F-1) slightly overlaps the left edge of the original image (5). The “slightly overlapping position” here refers to a position where the frame (F-1) and the original image (5) overlap even a little, and excludes a position where they do not overlap at all. Yes (Step 2-2). The original image (5) included in the frame (F-1) is used as the in-frame image (10-1), and the in-frame image (10-1) is compressed to the stereoscopic display image line width (W1) (Step 2 -3) The first stereoscopic display image line (6-1) is formed and arranged.

  Next, the position of the next frame (F-2) is determined by shifting the frame (F-1) to the right by a certain pitch. For the determined frame (F-2), the first stereoscopic display image line (6-2) is formed and arranged in the same manner as the leftmost frame (F-1) described above. Thereafter, similarly to the first frame (6-3, 6-4), the frame is sequentially moved to the right (F-3, F-4,..., Fn) while gradually shifting to the right. ,..., 6-n) are arranged and arranged to complete the first stereoscopic image line group (7). The position of the reference frame (F) is the left end of the original image (5). However, the position is not limited to this, and the center or the right end of the original image (5) may be used as a reference point. .

  In this way, the first stereoscopic display image line (6) is a compression of the in-frame image (10) divided based on the original image (5) at a predetermined reduction ratio in the horizontal direction, the vertical direction, or both directions. The first three-dimensional display lines (6) are all formed at the same reduction ratio.

  In the present invention, the “in-frame image (10) divided based on the original image (5)” means the center point of the original image (5) and the center point of the first stereoscopic display image line (6). Is specified at the center of the line width (W1) direction of each first stereoscopic display image line (6) forming the first stereoscopic image line group (7). When the center in the width direction of the frame (F) having a size of is fitted, it is the original image (5) that is contained in the frame (F). Therefore, since the original image (5) is not simply divided into a plurality of parts, for example, one intra-frame image (10-2) includes a part of the adjacent intra-frame image (10-1). In addition, another frame image (10-3) includes a part of the adjacent frame image (10-2). In this way, a part of the overlapping original image (5) exists in the adjacent intra-frame image (10).

  In addition, the compression direction of the in-frame image (10) is one that compresses the image in one direction such as the vertical direction or diagonal direction, and the compression in both the vertical and horizontal directions (simple reduction) is possible. It is. The “predetermined reduction ratio” in the present invention means that a plurality of first stereoscopic display image lines (6) forming one first stereoscopic display image line group (7) are all at the same reduction ratio. It means that there is. However, when compressing in both the vertical direction and the horizontal direction, the vertical reduction ratio and the horizontal reduction ratio may be different.

  As mentioned above, although the process (Step 2) for producing the 1st three-dimensional display image line group (7) in this invention was demonstrated easily, the further details are the patent 5200284 which this applicant has already disclosed. It is described in the gazette.

  Next, as shown in FIG. 13, in the processing unit (102), the hook-like basic image line (11) that is the basis of the first stereoscopic display image line (6) and the hook-like image line (8) is fixed. A saddle-like base line group forming step (Step 3) for forming a saddle-like base line group (12) arranged in the first direction (S1) at intervals is performed.

  The saddle-shaped base line group (12) has the same stroke width as the stroke width (W1) of the first stereoscopic display stroke (6) and has a predetermined stroke height (h). A plurality of lines (11) are regularly arranged in the first direction (S1) at the first pitch (P1) having the same pitch as the first stereoscopic display image line (6).

  The size of the saddle-shaped base line group (12) may be at least as large as the size of the first stereoscopic display line group (7). Accordingly, the size of the first direction (S1) is such that the first three-dimensional display image group (7) and the saddle-shaped basic image line group (12) have the same size. (11) may be arranged in a line, and in the second direction (S2) perpendicular to the first direction (S1), the longitudinal direction of the so-called saddle-shaped basic line (11), The first stereoscopic display image group (7) may have the same length as the size (T) in the height direction, but may be slightly longer than the first stereoscopic display image group (6). However, if it is shorter than the first stereoscopic display image line (6), the original image (5) cannot be accurately formed as the stereoscopic display image (4), which is not preferable.

  Next, in the processing unit (102), it is determined in what shape the 3D display image line (6) is to be formed on the embossed plate (9) (Step 4). As described with reference to FIGS. 3 to 6, the embossed plate (9) has a total of four shapes: a convex shape and two concave shapes. Whether the embossed plate (9) has a convex shape or a concave shape may be determined according to the shape of the embossed plate (9) formed on the formed body (1).

  When it is desired to form the first stereoscopic display image line (6) itself on the formed body (1) in a convex shape, the embossed plate (9) has the concave shape shown in FIG. In addition, in order to make the periphery of the first stereoscopic display image line (6) convex, it is determined whether the embossed plate (9) has a shape as shown in FIG.

  When it is desired to form the first stereoscopic display image line (6) itself on the formed body (1) in a concave shape, the embossed plate (9) has the convex shape shown in FIG. In addition, in order to make the periphery of the first stereoscopic display image line (6) concave, it is determined whether the embossed plate (9) has a shape as shown in FIG.

  Next, in the processing unit (102), an image line composition step (Step 5) in which the produced saddle-shaped basic image line group (12) and the first stereoscopic display image line group (7) are superimposed as shown in FIG. I do. Here, the length in the second direction (S2) of the above-described saddle-shaped base line (11) is illustrated again. As shown in FIG. 12, at least the saddle-shaped base line (11) is formed in the same size as the size (T) of the stereoscopic display line (6) in the second direction (S2). However, it may be slightly longer (for (K) and (L) in FIG. 12) than the size (T) for the stereoscopic display image line (11). In this step, in the case of the shape shown in FIGS. 3 and 4 in which the surface of the stereoscopic display image (6) itself has a bowl-shaped curved surface, height information is given to the composite image (13). To do.

  Further, as shown in FIGS. 5 and 6C, when the first stereoscopic display image line (6) is formed on the bowl-shaped image line (8), the above-described image line synthesis step (Step 5). Instead of the embossed plate (9), the saddle-like basic line group (12) produced in the saddle-like basic line group forming step (Step 3) is used as the concave or convex shape determined in the visual line shape determining step (Step 4). A saddle-shaped line drawing process (Step 5) is performed. It is important at this time that the surface layer of the image line is always formed to have a bowl-shaped curved surface.

  As a method of forming the concave or convex saddle-shaped image line (8) on the embossed plate (9), it can be processed by a known laser processing machine or an engraving machine using a cutting tool as described above. As the material of the embossed plate (9), for example, iron, copper, brass, stainless steel, aluminum alloy, and hard plastic can be used, but the substrate (2) can be pressed, and has a concave or convex shape. The material is not particularly limited as long as it can form a shape.

  After the image line synthesis step (Step 5) is finished, the embossed plate is produced by actually forming the convex or concave first stereoscopic display image line (6) on the embossed plate (9) by the processing unit (103). (Step 6), or the first three-dimensional display image on the embossed plate (9) on which the concave or convex saddle-shaped line group (12) has already been formed after the step (Step 5) is completed. A line (6) is formed to produce an embossed plate (Step 6).

  Finally, embossing for forming the first three-dimensional display image line (6) in the image forming area (3) on the base material (2) is performed using the produced embossed plate (9) (Step 7). . As a method for forming the first three-dimensional display image line (6) using the embossed plate (9) on the substrate (2), a known press working machine may be used. In addition, since the intaglio printing method uses strong pressure, the first three-dimensional display image line (6) of the present invention is formed on the intaglio plate surface, and blank printing without using ink can be performed. It is also possible to form the first stereoscopic display image line (6) on the top. Further, the first stereoscopic display image line (6) may be formed by using an ultraviolet curable resin.

  The configuration and the manufacturing method of the formed body (1) of the present invention have been described above. Next, the effect of the formed body (1) of the present invention will be described based on the principle.

  FIG. 15 shows the effect of the formed body (1) of the present invention. The shape of the first stereoscopic display image line (6) will be described as the convex shape shown in FIG. As shown in FIG. 15, by observing the formed body (1) of the present invention while changing the inclination with respect to the incident light (14), the position of the first stereoscopic display image (4) moves in the left-right direction. Looks like. This is because the observer's viewpoint (15) is slightly changed from FIG. 15 (a) to FIG. 15 (c), and the viewpoint (15) shown in FIG. The pattern of “cherry blossoms” that was slightly to the right of the center on the stereoscopic display image line (6) is closer to the center in the viewpoint (15 ′) shown in FIG. 15B, and further to FIG. 15C. From the viewpoint (15 ″) shown, the phase changes slightly to the left and is observed. The movement of this pattern is extremely smooth, and the right eye and the left eye appear to have different pattern positions, resulting in a stereoscopic effect due to binocular parallax. In the embodiment for carrying out the present invention, when the right eye is watching the pattern of FIG. 15C, the left eye is watching the pattern of FIG. The pattern "" is observed as if it protrudes toward the front side of the substrate surface. This principle will be described later.

  The principle that produces the above effects will be described. For example, when light is incident from the direction of the A side of the formed body (1), the surface of the first stereoscopic display image line (6) having a convex shape forming the first stereoscopic display image group (7) Of these, light is specularly strongly reflected only on the surface of the image line corresponding to the A side from the center of each image line. Conversely, when light is incident from the direction of the A ′ side of the formed body (1), Of the surface of one stereoscopic display image line (6), only the surface of the image line corresponding to the A ′ side direction from the center of each image line strongly reflects light.

  As described above, when an image line having a convex shape, such as the first stereoscopic display image line (6), reflects light, the surface of the image line that is normal to the incident light is centered on the incident light. In other words, the region where the light is strongly reflected on the surface of the image line having a bulge changes according to the angle of the incident light.

  The first stereoscopic display image line (6) is formed in a state where it is combined with the bowl-shaped base image line (11) and leaves only a common portion, and the surface of each image line is bowl-shaped. It is a curved surface. Therefore, the reflection of light is different between the place where the first stereoscopic display image line (6) having a bowl-shaped curved surface strongly reflects light and the position where a convex image line is substantially interrupted to form a step. Thus, the color changes to a different color (brightness or brightness), and the stereoscopic display image (4) is visualized by the difference in color (brightness or brightness).

  In this case, the first stereoscopic display image (4) to be visualized is only the first stereoscopic display image line (6) that strongly reflects light with respect to the viewpoint (15) of the observer, and the other three-dimensional display image (4). One stereoscopic display image line (6) remains unrecognized.

  For this reason, when light is incident, since the surface of the first stereoscopic display image line (6) is a bowl-shaped curved surface, a region that strongly reflects light is formed only on a part of the surface, Only the region that strongly reflects this light is sampled (taken out) and visualized. As a result of sampling, the same image as the first original image (5) is reproduced as a latent image.

  At this time, the latent image that appears when the width to be sampled, that is, the width of the region where each first stereoscopic display image line (6) strongly reflects light is narrower is the first original image ( Close to 5), the outline is sharp and the entire image is clearly reproduced.

  On the other hand, when the width is wide, the image is closer to the first stereoscopic display image line (6), and the outline is blurred and reproduced in an unclear state. In order to prevent this state, it is necessary to narrow the area where the image line having each bulge reflects light strongly, and the height of the image line having the bulge (increasing the curvature of the curved surface of the line) is increased. It is effective to do.

  When the observer's viewpoint moves or the formed body (1) is tilted, the angle at which the light enters changes, so that the first stereoscopic display image line (6) having a bowl-shaped curved surface on the surface is changed. Among them, the region where light is reflected is moved, and the region where the stereoscopic display image (4) is sampled is moved accordingly, so that the observer sees the first original image (5) that appears.

  In addition, when viewed directly facing the substrate (2), the right eye and the left eye are slightly different in the angle at which the incident light is reflected by the formed body (1) and enters the eye. The surface of the image line that reflects the light of the display image line (6) is also slightly different. For this reason, the appearing latent image has different horizontal phases when viewed from the right eye and when viewed from the left eye, thereby producing a stereoscopic visual effect due to binocular parallax.

  For example, when the first stereoscopic display image (4) is on the right when viewed from the left eye than when viewed from the right eye, the first stereoscopic display image (4) is the formed body (1 ) It seems to be in front of the surface. Conversely, when the first stereoscopic display image (4) is on the left when viewed from the left eye than when viewed from the right eye, the first stereoscopic display image (4) is the formed body ( It seems to be deeper than the surface of 1).

  In order to generate this three-dimensional visual effect, it is essential to have an effect that the image appears to move in the horizontal direction when viewed from the observer. Therefore, the first three-dimensional display image line (6) has an angle close to the vertical direction ( More specifically, this effect is enhanced by arranging in the direction orthogonal to the direction connecting the left and right eyes of the observer.

  As described above, in the formed body (1) of the present invention, when the formed body (1) strongly reflects light, the first original image (5) appears as a stereoscopic image, and the moving image effect and the stereoscopic visual effect are obtained. The resulting principle and effect.

  Next, a modified example of the formed body (1) will be described.

  FIG. 16 is a plan view showing a modification of the formed body (1). Note that the same points as those of the above-described embodiment will be omitted. Although this modification also has a three-dimensional and dynamic effect, it has a configuration in which the dynamic effect is improved as compared with the embodiment described above.

  As shown in FIG. 16, the formed body (1) has a first stereoscopic display image (4) and a second stereoscopic display image (16). Since the first stereoscopic display image (4) is the same image as the above-described stereoscopic display image, description thereof is omitted. As shown in FIG. 16, the second stereoscopic display image (16) is formed at a position close to or adjacent to the first stereoscopic display image (4). The first stereoscopic display image (4) is the same as the above-described embodiment, and the first original image (5) is “cherry blossoms”. Since the original image also exists for the display image (16), the original image for the second stereoscopic display image (16) is set as the second original image (19). In this modification, the first original image (5) and the second original image (19) are the same image “cherry blossoms”.

  The adjacent position is that the first stereoscopic display image (4) and the second stereoscopic display image (16) are formed adjacent to each other, and the adjacent position is the first stereoscopic display image. (4) and the second stereoscopic display image (16) are formed at positions close to the base material (2).

  It should be noted that, in the proximity or adjacent position, the first stereoscopic display image (4) and the second stereoscopic display image (16) are matched with the observer's visual field, the distance between the left and right eyes, and the first stereoscopic display image (16). Both the one stereoscopic display image (4) and the second stereoscopic display image (16) are set within a range of a distance (M) at which stereoscopic viewing is possible.

  The second stereoscopic display image line (18) constituting the second stereoscopic display image (16) and the first stereoscopic display image line (6) constituting the first stereoscopic display image (4). As shown in the enlarged view of FIG. 16, the mirror is inverted about the reference line (K) in the first direction (S1). A second stereoscopic display image (16) is formed by arranging a plurality of the second stereoscopic display image lines (18) which are mirror-inverted to form a second stereoscopic display image line group (17).

  The second stereoscopic display image (18) having the mirror-inverted shape is converted into each second stereoscopic display image (18) in the in-frame image forming step (Step 2-2) in the stereoscopic display image creation step (Step 2). ) Should be reversed.

  The dynamic effect on the first stereoscopic display image (4) is as described above, but the basic visual principle is the same for the dynamic effect on the second stereoscopic display image (16). Detailed description is omitted. In FIG. 17A, the first stereoscopic display image (4) in the present modification and the second stereoscopic display image (16) are formed at positions close to the first stereoscopic display image (4). The schematic diagram is shown. The second stereoscopic display image line (18) constituting the second stereoscopic display image (16) is the first stereoscopic display image group (7) forming the first stereoscopic display image (4). ) Is a mirror-inverted relationship in the left-right direction.

  FIG. 17B shows a diagram for explaining the dynamic effect. As described above, since the first stereoscopic display image group (7) and the second stereoscopic display image line (18) have a mirror-inverted relationship, the first original image (5) and the first The two original images (19) move in opposite directions, and a further dynamic effect is recognized by the synergistic effect of the two images moving in the opposite directions.

  In this modification, the first original image (5) that is the basis of the first stereoscopic display image (4) and the second original image (19) that is the basis of the second stereoscopic display image (16). Are described as the same image, but different images may be used.

  Hereinafter, examples of the specifically formed body (1) will be described in detail according to the above-described embodiment for carrying out the invention, but the present invention is not limited to these examples.

  As shown in FIG. 10, the first original image (5) uses “cherry blossoms” of about 10 mm long × 10 mm wide, and the width (F) of the first original image (5) when it is divided ( W2) was set to 5 mm, and this was compressed in the horizontal direction, and the width (W1) of the first stereoscopic display image line (6) was set to 0.5 mm. At this time, the first original image (5) is divided into a total of 29 frames (F) by setting the amount of shift of the frame (F) to 0.5 mm, and these frames (F) are compressed in the horizontal direction. The three-dimensional display image line (6) was arranged in the first direction (S1) at a pitch (P) of 0.5 mm and 29 sheets were arranged to create a first three-dimensional display image group (7).

  Next, a saddle-shaped basic line (11) having a length of 12 mm, a width of 0.5 mm, a cross-sectional shape of a radius of 2.4 mm, and an arcuate surface with an opening angle of 14 degrees has a pitch of 0 in the first direction (S1). 29 pieces were arranged at 5 mm to create a saddle-shaped basic line group (12). At this time, a rectangle having different widths was repeatedly engraved in accordance with the processing depth at the time of embossed plate engraving, so that a method of forming a bowl-shaped cross-sectional shape was used. A path was also created.

  Next, the first stereoscopic display image line group (7) and the saddle-shaped basic image line group (12) were superimposed and synthesized so that the left and right ends and the center of the group were aligned. At this time, the left and right ends and the centers of the first stereoscopic display image lines (6) and the saddle-shaped base image lines (11) are arranged to coincide with each other.

  Next, in order to form the first 3D display image line (6) having the same convex shape as in FIG. 3B, the area for forming the “cherry blossoms” of the first 3D display image line (6). All of the saddle-shaped base lines (11) overlapping with the plate were extracted and used as processing data for forming the embossed plate (9). As shown in FIG. 18 (a), the cross section of the embossed plate in the portion where the area forming the “cherry blossoms” of the first stereoscopic display image line (6) overlaps with the bowl-shaped basic image line (11) is The portion having a concave ridge shape without a chip and having a partially overlapping portion has a concave ridge-shaped cross section only in the overlapping portion.

  Next, based on the data for forming the embossed plate (9), a laser marker (MD-V9910 manufactured by Keyence) is used to make an iron plate with a matte surface of about 2 mm thickness, laser output 70%, scan speed 200 mm / s. Then, processing was repeatedly performed under the condition of a frequency of 20 kHz to form a concave first stereoscopic display image line (6) as shown in FIG. The deepest part of the concave shape of the embossed plate (9) was about 13 μm.

  When the embossed plate (9) after laser engraving is observed under appropriate illumination, the same “cherry blossoms” as the first original image (5) can be observed as a bright image at a position where the illumination light is regularly reflected. It was confirmed that the appearance position of the cherry blossoms that can be seen by changing the observation angle to the left and right also changes to the left and right.

  Finally, using the embossed plate (9), the multilayer interference film (REVI-SD900 manufactured by Lintec) was embossed at 120 ° C. and 20 kN, and the first three-dimensional display image having a convex shape as shown in FIG. When (6) was formed, it was confirmed that the appearance position of “Sakura no Hana” changed from side to side in accordance with the observation angle, as in the embossed plate (9).

  As shown in FIG. 10, the first original image (5) uses “cherry blossoms” of about 10 mm long × 10 mm wide, and the width (F) of the first original image (5) when it is divided ( W2) was set to 5 mm, and this was compressed in the horizontal direction, and the width (W1) of the first stereoscopic display image line (6) was set to 0.5 mm. At this time, the first original image (5) is divided into a total of 29 frames (F) by setting the amount of shift of the frame (F) to 0.5 mm, and these frames (F) are compressed in the horizontal direction. The three-dimensional display image line (6) was arranged in the first direction (S1) at a pitch (P) of 0.5 mm and 29 sheets were arranged to create a first three-dimensional display image group (7).

  Next, a saddle-shaped basic line (11) having a length of 12 mm, a width of 0.5 mm, a cross-sectional shape of a radius of 2.4 mm, and an arcuate surface with an opening angle of 14 degrees has a pitch of 0 in the first direction (S1). 29 pieces were arranged at 5 mm to create a saddle-shaped basic line group (12). At this time, a rectangle having different widths was repeatedly engraved in accordance with the processing depth at the time of embossed plate engraving, so that a method of forming a bowl-shaped cross-sectional shape was used. A path was also created.

  Next, the first stereoscopic display image line group (7) and the saddle-shaped basic image line group (12) were superimposed and synthesized so that the left and right ends and the center of the group were aligned. At this time, the left and right ends and the centers of the first stereoscopic display image lines (6) and the saddle-shaped base image lines (11) are arranged to coincide with each other.

  Next, in order to form a stereoscopic display image line having a convex shape similar to that of FIG. 6C, a saddle shape that does not overlap with the area where the “cherry blossoms” of the first stereoscopic display image line (6) is formed. The base line (11) leaves a sculpture path that forms a hook-shaped cross-sectional shape, and all the hook-shaped base lines (11) of the area forming the “cherry blossoms” are processed data for engraving at the same depth. As shown in FIG. 19 (a), the cross section of the embossed plate in the portion where the area forming the “cherry blossoms” of the first stereoscopic display image line (6) overlaps with the bowl-shaped basic image line (11), It is a flat rectangular convex shape, and the partially overlapping portion has a rectangular convex shape in the overlapping portion and a convex saddle-shaped cross section in the non-overlapping portion.

  Next, based on the data for forming the embossed plate (9), a laser marker (MD-V9910 manufactured by Keyence) is used to make an iron plate with a matte surface of about 2 mm thickness, laser output 70%, scan speed 200 mm / s. Then, processing was repeated under the condition of a frequency of 20 kHz to form a convex first stereoscopic display image line (6) as shown in FIG. The highest part of the convex shape of the embossed plate (9) was about 13 μm.

  When the embossed plate (9) after laser engraving is observed under appropriate illumination, the parts other than the same “cherry blossoms” as the original image are bright and the “cherry blossoms” are observed as dark images at the position where the illumination light is regularly reflected. It was also possible to confirm that the appearance position of the cherry blossoms that can be seen by changing the observation angle in the horizontal direction also changes in the horizontal direction.

  Finally, using the embossed plate (9), the multilayer interference film (REVI-SD900 manufactured by Lintec) was embossed at 120 ° C. and 20 kN, and the first stereoscopic display image having a concave shape as shown in FIG. When (6) was formed, it was confirmed that the appearance position of “Sakura no Hana” changed from side to side in accordance with the observation angle, as in the embossed plate (9).
