A forming layer may be formed, and the image forming medium may be provided on a lenticular sheet or a plano-convex lens sheet.

  FIG. 5 is a cross-sectional view of an image display sheet provided in the image display body.

  The image display sheet 100 is formed with the lenticular sheet 1 and the image forming layer 3 as essential components. In the present embodiment, an example in which the image forming layer 3 is formed on the image forming medium 2 such as paper will be described. Below, each layer which comprises the image display sheet 100 is demonstrated.

  The lenticular sheet 1 is configured by arranging a plurality of cylindrical lenses 1a in parallel. A cylindrical lens 1a formed on the lenticular sheet 1 is shown in the upper part of the drawing. The material of the lenticular sheet 1 is not particularly limited as long as it is a lens sheet conventionally used for an image display sheet, but is a transparent resin material such as PET (polyethylene terephthalate), PP, PETG (glycol-modified polyethylene terephthalate), and acrylic. Is used.

  The image forming medium 2 is provided on the side of the lenticular sheet 1 that does not have the convex shape of the cylindrical lens 1a, and the image forming layer 3 is formed on the lenticular sheet 1 side. The material of the image forming medium 2 is not particularly limited as long as it is an image forming medium conventionally used for an image display sheet, but is not limited to coated paper, synthetic paper, fine paper, medium paper, impregnated paper, laminated paper, metal vapor deposition. Paper, paper such as coated paper for printing, coated paper for recording, polyethylene terephthalate film, polyethylene film, polypropylene film, plastic film such as polycarbonate film, metal foil, wood, metal, or a composite thereof is used. . The material of the image forming medium 2 can be appropriately selected according to the strength and application required for the image display sheet 100.

  The image forming layer 3 is a layer in which an image 3a such as a pattern or a character, which is a virtual image observation image, is formed by printing or transfer. The image forming layer 3 is provided on the lenticular sheet 1 side of the image forming medium 2. The material of the image forming layer 3 is not particularly limited as long as it can adhere to the image forming medium 2. For example, a conventionally known ink material is used. The ink material may be phosphorescent ink, fluorescent ink, or the like.

  Further, as a method of laminating the lenticular sheet 1 and the image forming medium 2 provided with the image forming layer 3, a known method such as adhesion or adhesion is used depending on the material of the image forming medium 2 and the image forming layer 3. Done. It is sufficient that the lenticular sheet 1 and the image forming layer 3 can be laminated while maintaining transparency. That is, it is only necessary that the observer can observe the image 3 a formed on the image forming layer 3 from the side of the cylindrical lens 1 a having the convex shape of the lenticular sheet 1. Specifically, it is only necessary to observe a movement based on the image 3a formed on the image forming layer 3, or a virtual image accompanied by movement and deformation.

  FIG. 6 is an explanatory diagram of a configuration of an image display sheet provided in the image display body. 6A is a cross-sectional explanatory view of the lenticular sheet, and FIG. 6B is a plan view of the image forming layer. FIG. 7 is a plan view of an image display sheet provided in the image display body.

  In the example of FIG. 6A, when the observer changes the viewing angle and moves the line of sight, the state of the focus by each cylindrical lens 1a when the observer observes from directly above each cylindrical lens 1a is shown. The focusing surface of the cylindrical lens 1 a is in the image forming layer 3. In other words, the cylindrical lens 1a is configured to focus on the image 3a. In practice, the observer is not limited to seeing from just above, but can change the viewing angle and confirm the smooth movement or movement and deformation of the virtual image.

  As shown in FIG. 6B, a plurality of images 3 a are formed on the image forming layer 3. In the example of FIGS. 6A and 6B, the image 3a is repeatedly formed so as to substantially correspond to the cylindrical lens 1a. Each of the six eyeball images 3a corresponds to the cylindrical lens 1a.

  The difference between the arrangement pitch length A of the cylindrical lens 1a and the pitch length B of the image 3a is in a range of 0% to 10% with respect to the arrangement pitch length A of the cylindrical lens 1a or the pitch length B of the image 3a. . That is, when the arrangement pitch length A of the cylindrical lenses 1a and the pitch length B of the image 3a are equal (A = B), the difference is 0%, and when the difference is different (A <B or A> B). The difference is in the range of more than 0% and not more than 10%.

  In the example shown in FIG. 6, the arrangement pitch length A of the cylindrical lenses 1a and the pitch length B of the image 3a are configured to be different, and the difference between the arrangement pitch length A of the cylindrical lenses 1a and the pitch length B of the image 3a is It is configured to be 10% or less with respect to the arrangement pitch length A of the cylindrical lenses 1a or the pitch length B of the image 3a.

  When the pitch length B of the image 3a is smaller than the arrangement pitch length A of the cylindrical lenses 1a (A> B), the observer sinks the virtual image 4 based on the cylindrical lens 1a and the image 3a below the lenticular sheet 1. Looks three-dimensional. When the line of sight is moved to the right, the virtual image 4 also appears to move to the right, and when it moves to the left, the virtual image 4 appears to move to the left. That is, the virtual image 4 appears to move in the same direction as the line of sight movement.

  When the pitch length B of the image 3a is larger than the arrangement pitch length A of the cylindrical lenses 1a (A <B), the observer floats the virtual image 4 based on the cylindrical lens 1a and the image 3a above the lenticular sheet 1. Looks three-dimensional. When the line of sight is moved to the right, the virtual image 4 appears to move to the left, and when the line of sight is moved to the left, the virtual image 4 appears to move to the right. That is, the virtual image 4 appears to move in the direction opposite to the line of sight movement.

The pitch length x of the virtual image 4 shown in FIG. 7 is determined based on Expression (1). The width y in the arrangement direction of the cylindrical lenses 1a of the virtual image 4 is determined based on Expression (2). A is the arrangement pitch length of the cylindrical lenses 1a, B is the pitch length of the image 3a, and C is the width (lateral size) of the cylindrical lenses 1a in the arrangement direction of the image 3a. The height z (vertical size) of the virtual image 4 in the direction orthogonal to the arrangement direction of the cylindrical lenses 1a is the same as the height D (vertical size) of the image 3a in the direction orthogonal to the arrangement direction of the cylindrical lenses 1a. (Formula (3)).

  Thus, by appropriately adjusting and changing the arrangement pitch length A of the cylindrical lenses 1a, the pitch length B of the images 3a, the width C of the arrangement directions of the cylindrical lenses 1a of the images 3a, and the heights D of the images 3a, the above formulas are obtained. The size of the virtual image 4 observed based on (1) to Expression (3) can be freely set.

  FIG. 8 is an explanatory diagram of a virtual image. As the observer changes the viewing angle and moves the line of sight, the image 3a formed on the image forming layer 3 and the virtual image 4 based on the cylindrical lens 1a can be observed from above the lenticular sheet 1 as a pseudo-dynamic image.

  Specifically, when the pitch length B of the image 3a is smaller than the arrangement pitch length A of the cylindrical lenses 1a (A> B), the virtual image 4 sinks below the lenticular sheet 1 and looks three-dimensional. Furthermore, the virtual image 4 is observed as a virtual image that moves smoothly with the movement of the observer's line of sight.

  On the other hand, when the pitch length B of the image 3a is larger than the arrangement pitch length A of the cylindrical lenses 1a (A <B), the virtual image 4 floats above the lenticular sheet 1 and looks three-dimensional. Furthermore, the virtual image 4 is observed as a virtual image that moves smoothly with the movement of the observer's line of sight.

  In Expressions (1) and (2), the smaller the value of | A−B |, the faster the movement speed of the observer relative to the line of sight movement. Therefore, it is preferable to set the value of | A−B | according to the usage state of the image display sheet 100, that is, in consideration of the speed of the actual observer's line-of-sight movement. In other words, when the observer moves the line of sight and observes the virtual image 4, it is desirable to set the moving speed of the virtual image 4 to match the speed of the line of sight movement.

  According to the present embodiment, a plurality of images 3 a for causing the image forming layer 3 to act with the cylindrical lens 1 a to display a virtual image are repeatedly formed so as to substantially correspond to the cylindrical lens 1 a of the lenticular sheet 1. The difference between the arrangement pitch length A of the cylindrical lens 1a and the pitch length B of the image 3a is in a range of 0% to 10% with respect to the arrangement pitch length A of the cylindrical lens 1a or the pitch length B of the image 3a. Since it comprised, the image display sheet which can observe the virtual image 4 with a smooth movement or a movement and a deformation | transformation is realizable. In addition, since the size (width C, height D) of the image 3a is about several hundred μm to several tens of mm, general-purpose equipment (for example, general-purpose printing apparatus, transfer apparatus, etc.) can be used without using dedicated equipment. The image forming layer 3 can be printed and transferred to the image forming medium 2 using general-purpose image software.

  Moreover, according to the image display body of the first embodiment to the sixth embodiment provided with such an image display sheet 100, the lenticular sheet 1 and the image forming layer 3 configured by the arrangement of the plurality of cylindrical lenses 1a are laminated. An image display sheet 100 configured such that an image formed on the image forming layer 3 can be moved or observed as a virtual image accompanied by movement and deformation from the side having the convex shape of the cylindrical lens 1a of the lenticular sheet 1 A plurality of images 3a for displaying a virtual image by acting on the cylindrical lens 1a on the image forming layer 3 of the image display sheet 100 are substantially paired with each cylindrical lens 1a. Are formed so as to correspond to one, and the arrangement pitch length A of the cylindrical lenses and the pitch length B of the image 3a Is configured to be in a range of 0% to 10% with respect to the arrangement pitch length A of the cylindrical lenses 1a or the pitch length B of the image 3a, and the base material and the image display sheet 100 are configured to be laminated. Therefore, it is possible to realize an image display body to which a smooth pseudo moving image is realized and an image display sheet that can be observed with reduced discomfort is attached.

  Further, according to the image display body of the seventh embodiment to the eleventh embodiment provided with such an image display sheet 100, the lenticular sheet 1 and the image forming layer 3 configured by the arrangement of the plurality of cylindrical lenses 1a are provided. An image display sheet 100 configured to be laminated and configured so that an image formed on the image forming layer 3 can be moved or observed as a virtual image with movement and deformation from the side of the cylindrical lens 1a having the convex shape of the lenticular sheet 1a. And a plurality of images 3a for displaying a virtual image by acting on the cylindrical lens 1a on the image forming layer 3 of the image display sheet 100, which is substantially the same as each cylindrical lens 1a. It is repeatedly formed so as to correspond one-to-one, the arrangement pitch length A of the cylindrical lenses, and the pitch length B of the image 3a. The difference is configured to be in a range of 0% to 10% with respect to the arrangement pitch length A of the cylindrical lenses 1a or the pitch length B of the image 3a, and the base material has a cut-out mounting portion, and the mounting portion Since the image display sheet 100 is attached to the image display sheet 100, it is possible to realize an image display body to which an image display sheet that can be observed while realizing a smooth pseudo moving image and reducing discomfort.

  The image 3a is repeatedly formed so as to substantially correspond to the cylindrical lens 1a, but when the arrangement pitch length A of the cylindrical lenses 1a and the pitch length B of the image 3a are different, the corresponding positions are gradually shifted. Go. Therefore, some cylindrical lenses 1a and the image 3a do not correspond one to one. A smooth virtual image can be observed when the arrangement pitch length A of the cylindrical lenses 1a and the pitch length B of the image 3a are different.

Since other configurations are the same as those of the image forming layer 3 or the image forming layer 6 described above, the description thereof is omitted.

  As described above, the image forming layer 3 or the image forming layer 6 may be directly formed on the lenticular sheet 8.

(Other embodiment 3)
The image display sheet provided in the image display body of the present invention can be combined with a stereoscopic sheet. As another embodiment 3, an embodiment in which an image display sheet is combined with a stereoscopic sheet will be described.

  FIG. 14 is an explanatory diagram of a configuration of an image display sheet according to another embodiment 3. (A) is sectional drawing of an image display sheet, (B) is a top view of an image forming layer.

  The image display sheet 400 includes a virtual image display unit 40a and an observed image display unit 40b.

  The virtual image display unit 40a includes the lenticular sheet 10 common to the observed image display unit 40b, the image forming medium 11 common to the observed image display unit 40b, and the image forming layer 12. The observed image display unit 40b includes the lenticular sheet 10 that is common to the virtual image display unit 40a, the image forming medium 11 that is common to the virtual image display unit 40a, and the image forming layer 13.

  The configuration of the lenticular sheet 10 is the same as that of the lenticular sheet 1 described above, the configuration of the image forming medium 11 is the same as that of the image forming medium 2 described above, and the configuration of the image forming layer 12 is the image forming layer 3 or the image forming layer described above. Since it is the same as that of the layer 6, description is abbreviate | omitted. In the example of FIG. 14, an image 12 a as a virtual image observation image is formed on the image forming layer 12.

  The image forming medium 11 is an image forming medium common to the virtual image display unit 40a and the observed image display unit 40b. The image forming layers 12 and 13 are formed on the lenticular sheet 10 side. Since the other configuration of the image forming medium 11 is the same as that of the image forming medium 2 described above, description thereof is omitted.

  The observed image display unit 40b has the configuration and effects of a conventionally known lenticular display. The image forming layer 13 of the observed image display unit 40b is a layer in which one or a plurality of other images different from the virtual image observation image (the image 12a in the present embodiment) are formed by printing or transfer. The other image is an image such as a pattern or a character which is a stereoscopic image, a changing image, an animation image, or the like. In the example of FIG. 14B, a left-eye image 13a and a right-eye image 13b that display an image to be observed by acting with the cylindrical lens 10a of the lenticular sheet 10 are arranged in stripes. The material of the image forming layer 13 is not particularly limited as long as it can adhere to the image forming medium 11. For example, a conventionally known ink material or the like is used.

  The lamination method of the lenticular sheet 10 and the image forming medium 11 is performed using a known method such as adhesion or adhesion depending on the materials of the image forming medium 11 and the image forming layers 12 and 13. It is sufficient that the lenticular sheet 10 and the image forming layers 12 and 13 can be laminated while maintaining transparency.

  When the observer changes his / her line of sight by changing the viewing angle from above the lenticular sheet 10, the virtual image display unit 40a can observe the virtual image by the action of the image on the image forming layer 12 and the cylindrical lens 10a, and the observed image display unit 40b. Then, the image on the image forming layer 13 and the cylindrical lens 10a act to observe the observed image.

  As described above, the image display sheet 400 can be configured by combining the virtual image display unit 40a capable of observing a virtual image and the observed image display unit 40b capable of observing the observed image. In FIG. 14, the case of using two virtual image display units 40 a and three observed image display units 40 b has been described as an example in order to simplify the description and illustration. However, a desired number of ( A plurality of (single or plural) virtual image display units 40a and a desired number (single or plural) of observed image display units 40b may be combined.

  According to the image display sheet 400 of the third embodiment, since the virtual image display unit 40a and the observed image display unit 40b are configured by the same image forming medium 11, a simpler and more stable sheet can be realized. For example, when creating an image display sheet representing the face (face) of a Kabuki actor, the part of both eyes is formed by the virtual image display part 40a, and the part other than both eyes is formed by the observed image display part 40b. Thus, it is possible to express the surface of a three-dimensional kabuki actor in which only both eyes move smoothly.

(Other embodiment 4)
It is also possible to constitute an image display sheet provided in the image display body of the present invention using a plano-convex lens sheet. As another embodiment 3, an embodiment in which a plano-convex lens sheet is used will be described.

  FIG. 15 is a cross-sectional view of an image display sheet according to another embodiment 4.

  The image display sheet 500 is formed with the plano-convex lens sheet 15 and the image forming layer 17 as essential components. Here, an example in which the image forming layer 16 is formed on an image forming medium such as paper will be described. Below, each layer which comprises the image display sheet 500 is demonstrated.

  The plano-convex lens sheet 15 is configured by a honeycomb arrangement or a square arrangement of a plurality of plano-convex lenses 15a. The plano-convex lens 15a configured on the plano-convex lens sheet 15 is shown in the upper part of the drawing. The material of the plano-convex lens sheet 15 is not particularly limited as long as it is a lens sheet conventionally used for an image display sheet, but is a transparent resin such as PET (polyethylene terephthalate), PP, PETG (glycol-modified polyethylene terephthalate), and acrylic. Material is used.

  The image forming medium 16 is provided on the side of the plano-convex lens sheet 15 that does not have the convex shape of the plano-convex lens 15a, and the image forming layer 16 is formed on the plano-convex lens sheet 15 side. Since other configurations of the image forming medium 16 are the same as those of the image forming medium 2 described above, description thereof will be omitted.

  The image forming layer 17 is a layer in which an image 17a such as a pattern or a character, which is a virtual image observation image, is formed by printing or transferring. The image forming layer 17 is provided on the plano-convex lens sheet 15 side of the image forming medium 16. The material of the image forming layer 3 is not particularly limited as long as it can adhere to the image forming medium 2. For example, a conventionally known ink material is used. The ink material may be phosphorescent ink, fluorescent ink, or the like. Since the other structure of the image forming layer 17 is the same as that of the image forming layer 3 described above, the description thereof is omitted.

  The focus surface of the plano-convex lens 15 a is in the image forming layer 17. In other words, the plano-convex lens 15a is configured to focus on the image 17a. The lamination method of the plano-convex lens sheet 15 and the image forming medium 16 provided with the image forming layer 17 uses a known method such as adhesion or adhesion depending on the material of the image forming medium 16 and the image forming layer 17. Done. It is only necessary that the plano-convex lens sheet 15 and the image forming layer 17 can be laminated while maintaining transparency. That is, it is only necessary that the observer can observe the image 17a formed on the image forming layer 17 from the side of the planoconvex lens sheet 15 having the convex shape of the planoconvex lens 15a. Specifically, it is only necessary to observe a movement based on the image 17a formed on the image forming layer 17, or a virtual image accompanying movement and deformation.

  FIG. 16 is an explanatory diagram of a configuration of an image display sheet according to another embodiment 4. (A) is a plan view of a plano-convex lens sheet, and (B) is a plan view of an image forming layer. FIGS. 17 and 18 are diagrams illustrating the configuration of a virtual image according to the fourth embodiment.

  A plurality of plano-convex lenses 15 a are formed on the plano-convex lens sheet 15. FIG. 16A shows an example of a plano-convex lens sheet 15 having a honeycomb arrangement. As shown in FIG. 16B, a plurality of images 17 a are formed on the image forming layer 17. The image 17a is repeatedly formed so as to substantially correspond to the plano-convex lens 15a. In the example of FIGS. 16A and 16B, 30 eyeball images 17a correspond to the plano-convex lens 15a, respectively.

The arrangement pitch length of the plano-convex lens 15a and the pitch length of the image 17a are different, and the difference between the arrangement pitch length of the plano-convex lens 15a and the pitch length of the image 17a is the pitch of the arrangement pitch length of the plano-convex lens 15a or the pitch of the image 17a. It is configured to be 10% or less with respect to the length. In the example of FIG. 16, configured to pitch length B ₁ of FIG arrangement pitch length A ₁ and the image 17a in the figure next to the plano-convex lens 15a (horizontal) lateral differ, and the difference is plano-convex lens 15a to pitch length _{B 1} of the array pitch length _{a 1} or the image 17a and configured to be 10% or less, the pitch of FIG lateral array pitch length _{a 2} and the image 17a of the vertical in the figure in the plano-convex lens 15a (vertical direction) configured to length _{B 2} are different, and, with respect to pitch length _{B 2} of the arrangement pitch length _{a 2} or the image 17a of the difference is a plano-convex lens 15a is configured to be 10% or less.

When the pitch length B ₁ (B ₂ ) of the image 17a is smaller than the arrangement pitch length A ₁ (A ₂ ) of the plano-convex lens 15a (A ₁ > B ₁ and A ₂ > B ₂ ), the observer The virtual image 18 based on the plano-convex lens 15a and the image 17a sinks below the plano-convex lens sheet 15 and appears three-dimensionally. Then, as shown in FIG. 17, when the line of sight is moved to the right, the virtual image 18 also appears to move to the right, and when it moves to the left, the virtual image 18 also appears to move to the left. That is, the virtual image 18 appears to move in the same direction as the line of sight movement.

When the pitch length B ₁ (B ₂ ) of the image 17a is larger than the arrangement pitch length A ₁ (A ₂ ) of the plano-convex lens 15a (A ₁ <B ₁ and A ₂ <B ₂ ), the observer The virtual image 18 based on the plano-convex lens 15 a and the image 17 a floats above the plano-convex lens sheet 15 and appears three-dimensionally. When the line of sight moves to the right, the virtual image 18 appears to move to the left, and when the line of sight moves to the left, the virtual image 18 appears to move to the right. That is, the virtual image 18 appears to move in the direction opposite to the line-of-sight movement.

  As shown in FIGS. 17 and 18, when the observer changes his / her line of sight, the virtual image 18 based on the image 17 a formed on the image forming layer 17 and the plano-convex lens 15 a is formed on the plano-convex lens sheet 15. Observable from above. FIG. 17 shows a state of the virtual image 18 when the line of sight is moved in the horizontal direction. FIG. 17 shows a state of the virtual image 18 when the line of sight is moved in the vertical direction.

Pitch length _{x 1} of the virtual image 18 shown in FIG. 18 is determined based on equation (1). The horizontal width y ₁ of the virtual image 18 is determined based on Expression (2). In this case, A is the array pitch length _{A 1} of the plano-convex lens 15a, B is the pitch length _{B 1} of the horizontal direction of the image 17a, C is the width _{C 1} in the horizontal direction of the image 17a (horizontal size).

Pitch length _{x 2} of the virtual image 18 shown in FIG. 18 is determined based on equation (1). The vertical width y ₂ of the virtual image 18 is determined based on Expression (2). At this time, A is the arrangement pitch length A ₂ of the plano-convex lenses 15a, B is the vertical pitch length B ₂ of the image 17a, and C is the vertical height C ₂ (vertical size) of the image 17a. .

  In Expressions (1) and (2), the smaller the value of | A−B |, the faster the movement speed of the observer relative to the line of sight movement. Therefore, it is preferable to set the value of | A−B | in accordance with the usage state of the image display sheet 500, that is, in view of the speed of the actual observer's line-of-sight movement. In other words, when the observer moves the line of sight and observes the virtual image 18, it is desirable to set the moving speed of the virtual image 18 to match the speed of the line of sight movement.

  With the configuration described above, it is possible to realize the image display sheet 500 that can observe a virtual image that moves smoothly even if a plano-convex lens sheet is used. When the observer changes the viewing angle and moves the line of sight, the virtual image 18 based on the image 17a formed on the image forming layer 17 and the plano-convex lens 15a can be observed.

  Although the image forming layer 17 is formed on the image forming medium 16, it may be directly formed on the surface opposite to the surface having the plano-convex lens of the plano-convex lens sheet 15 according to the other embodiment 2 described above. Further, the image display sheet 500 is configured in combination with a conventionally known stereoscopic sheet according to the other embodiment 3 described above, and can observe an observed image by the action of a stereoscopic image, a changing image, an animation image, or a combination thereof. You can also In this case, the image 17a functions as the virtual image observation image of the present invention.

Furthermore, the image display sheet 500 can constitute an image display sheet for observing only one virtual image according to the other embodiment 1 described above. Hereinafter, this will be described in detail as another embodiment 5.
(Other embodiment 5)
An image forming layer when observing only one virtual image using a plano-convex lens sheet will be described. The plano-convex lens sheet and the image forming medium have the same configurations as those of the other embodiment 4.

  FIG. 19 is a plan view of an image forming layer of an image display sheet according to another embodiment 5.

  On the image forming layer 19, a predetermined number of images 19a and 19b, which are virtual image observation image groups, are formed. The image 19a in the vicinity of the center of the image group is an image that is not missing, and the other images 19b other than the image 19a in the vicinity of the center have a notch 19c on the side of the image 19a near the center. The images 19a and 19b are formed so as to substantially correspond to a plano-convex lens (not shown).

  In the example of FIG. 19, the image group includes an image 19a near the center and a plurality of images 19b having a notch 19c. The notch portion 19c of the image 19b becomes larger as the distance from the image 19a increases. Although FIG. 19 shows the case where there is one image 19a near the center, the number of images 19a near the center may be plural.

The arrangement pitch length of the plano-convex lens is different from the pitch length of the images 19a and 19b, and the difference between the arrangement pitch length of the plano-convex lens and the pitch length of the images 19a and 19b is the arrangement pitch length of the plano-convex lens or the image 19a. And 19b with respect to the pitch length of 19b. Specifically, a plano-convex lens in the horizontal direction of the array pitch lengths A ₁ and the pitch length B ₁ in the horizontal direction constitute different image 19a, the horizontal arrangement pitch length A ₁ or the image 19a of the difference is a plano-convex lens constituting the horizontal pitch length B ₁ to so as to be 10% or less. The pitch length B ₂ in the vertical direction is configured differently plano vertical arrangement pitch length A ₂ and the image 19a, the vertical direction of the difference is a plano-convex lens in the vertical direction of the arrangement pitch length A ₂ or the image 19a configuring such that the relative pitch length _{B 2} 10% or less. The pitch length _{B 1} and _{B 2} between the image 19a and the image 19b, the pitch length _{B 1} and _{B 2} between the image 19b, the pitch length between the image 19b, assuming that there is no out portion 19c is the image 19b B and ₁ and _{B 2.}

Pitch length x ₁ in the horizontal direction of the virtual image (not shown) is determined based on equation (1). The horizontal width y ₁ of the virtual image is determined based on Expression (2). At this time, A is the arrangement pitch length A ₁ of the plano-convex lenses, B is the horizontal pitch length B ₁ of the images 19a and 19b, and C is the horizontal width C ₁ (horizontal size) of the image 19a. .

The pitch length x ₂ in the vertical direction of the virtual image (not shown) is determined based on equation (1). The vertical width y ₂ of the virtual image is determined based on Expression (2). At this time, A is the arrangement pitch length A ₂ of the plano-convex lenses, B is the vertical pitch length B ₂ of the images 19a and 19b, and C is the vertical height C ₂ (vertical size) of the images 19a and 19b. ).

  With the configuration described above, it is possible to realize an image display sheet that can observe only one virtual image that moves smoothly even if a plano-convex lens sheet is used. As the observer changes the viewing angle and moves the line of sight, one virtual image in which the center image is prominently displayed can be observed based on the images 19a and 19b formed on the image forming layer 19 and the plano-convex lens.

  The above-described embodiments can be implemented in combination. For example, in another embodiment 3, the image forming layer may be provided directly on the surface of the lenticular sheet opposite to the surface having the convex shape of the cylindrical lens in accordance with the other embodiment 2. Further, in other embodiment 4 and other embodiment 5, the image forming layer may be directly provided on the surface of the plano-convex lens sheet opposite to the surface having the convex shape of the plano-convex lens according to other embodiment 2. .

  In the above-described embodiment, description has been made along the example in which the centerpiece is a virtual image observation image. However, not only the centerpiece but also a virtual image based on various images such as patterns and characters can be observed. In particular, if a closed eyeball image and an open eyeball image are used as the virtual image observation image, a virtual image with deformation that opens and closes the eyes can be observed. In addition, if an image of an open mouth and an image of a closed mouth, or an image of an open flower and an image of a closed flower are used as virtual image observation images, there are a wide variety of movements and deformations. A virtual image can be realized. Hereinafter, the case where the image of the arrow is a virtual image observation image will be described with reference to FIG.

(Other embodiment 6)
FIG. 20 is a plan view of an image forming layer of an image display sheet according to another embodiment 6. FIG. 20A and FIG. 20B are examples of an image forming layer in which an arrow is a virtual image observation image.

  A plurality of images 20a as virtual image observation images are formed on the image forming layer 20 shown in FIG. The image 20a is repeatedly formed so as to substantially correspond to a cylindrical lens (not shown) of the lenticular sheet. The arrangement pitch length of the cylindrical lenses and the pitch length B of the image 20a are configured to be different, and the difference is configured to be 10% or less with respect to the arrangement pitch length of the cylindrical lenses or the pitch length B of the image 20a. The image forming layer 20 may be formed on an image forming medium (not shown), or may be directly formed on a lenticular sheet as in the second embodiment. When the image forming layer 20 is formed on the image forming medium, the configuration of the image forming medium may be the same as that of the image forming medium 2 described above.

  A virtual image indicating an arrow based on the image 20a and the cylindrical lens can be observed from above the lenticular as a pseudo dynamic image. Also, by appropriately adjusting and changing the arrangement pitch length of the cylindrical lenses, the pitch length B of the image 20a, the width C of the image 20a in the arrangement direction of the cylindrical lenses, and the height D of the image 20a, the above formulas (1) to (1) The size of the virtual image observed based on (3) can be freely set.

  A plurality of images 21a as virtual image observation images are formed on the image forming layer 21 shown in FIG. Since the configuration of the image 21a is the same as the configuration of the image 20a, description thereof is omitted.

  A virtual image indicating an arrow based on the image 21a and a cylindrical lens (not shown) can be observed from above the lenticular as a pseudo dynamic image. Further, by appropriately adjusting and changing the arrangement pitch length of the cylindrical lenses, the pitch length B of the image 20a, the width C of the image 21a in the arrangement direction of the cylindrical lenses, and the height D of the image 21a, the above expressions (1) to (1) The size of the virtual image observed based on (3) can be freely set.

  When the pitch length B of the image 20a (or the image 21a) is smaller than the arrangement pitch length A (not shown) of the cylindrical lenses (A> B), the observer can see the cylindrical lens and the image 20a (or the image 21a). A virtual image showing an arrow based on it sinks below the lenticular sheet and appears three-dimensional. When the line of sight is moved to the right, the virtual image indicating the arrow appears to move to the right, and when the line of sight is moved to the left, the virtual image indicating the arrow also appears to move to the left. That is, a virtual image indicating an arrow appears to move in the same direction as the line of sight movement. Since the virtual image indicating the arrow along with the direction of movement of the person appears to move in the same direction, it can be effectively used for guiding the direction of travel.

  On the other hand, when the pitch length B of the image 20a (or the image 21a) is larger than the arrangement pitch length A (not shown) of the cylindrical lenses (A <B), the observer can connect the cylindrical lens and the image 20a (or the image 21a). A virtual image showing an arrow based on () floats above the lenticular sheet and appears three-dimensional. At this time, the observer sees a virtual image having a shape obtained by rotating the image 20a (or the image 21a) by 180 degrees. When the line of sight is moved to the right, the virtual image indicating the arrow appears to move to the left, and when the line of sight is moved to the left, the virtual image indicating the arrow appears to move to the right. That is, the virtual image indicating the arrow appears to move in the direction opposite to the line-of-sight movement. A person can be effectively used for guidance in the direction opposite to the traveling direction.

  A convex body such as a plano-convex lens or a meniscus lens may be provided above the lenticular sheet. Hereinafter, description will be given with reference to the drawings.
