JP5243986B2 - Variable image display - Google Patents

Description

  The present invention relates to a variable image display capable of sequentially switching and displaying a plurality of types of images on the same display unit by a simple operation.

  A striped screen in which thin-line perspective parts and concealment parts are alternately arranged is superimposed on a composite thin-line image in which multiple types of original images are divided into thin lines and arranged periodically. The variable image display body that is displayed so that the image displayed on the display unit changes into a completely different image instantaneously by sliding, or is displayed as a moving image that continuously changes is disclosed in Patent Documents 1 to 3. As is shown in FIG. Such a variable image display is a toy, a picture book, a hobby / entertainment product, an advertisement as a display that can change images and display videos without the need for any special materials, power supply / control device, etc. with a simple structure. It is used for promotional materials and other various purposes.

  The relative sliding between the composite thin line image and the striped screen in the variable image display body is not a simple one, for example, as shown in Patent Documents 1 to 3, the composite thin line image carrier and the screen carrier. In many cases, this is performed by a manual operation directly held by a person. However, with this method, it is difficult to precisely align the two or slide them smoothly, so that only the desired image can be displayed cleanly from multiple types of images, Smooth display is somewhat difficult because it requires careful manual operation. In particular, in order to increase the number of patterns of image change or to display moving images more smoothly, the number of original images is increased while the fineness of the displayed image is reduced in order not to reduce the definition of the displayed image. The problem becomes more prominent as the line is thinned and the screen period is made finer.

  Therefore, as a solution to such a problem, a linear shape perpendicular to the sliding direction is provided at one end of the mount in the relative sliding direction between the composite thin line image and the screen of the mount in the variable image display body. A hinge mechanism having a swingable operating piece extending so as to be bent through the folding line, and a position at a slight predetermined distance from the folding line in the operating piece (the folding curve) Than the end portion side of the operation piece portion, and a portion of the operation piece portion that extends beyond the folding line to the side opposite the end portion side). A composite thin line image or one carrier of the screen is connected, and the other carrier is structured so that its position with respect to the mount is fixed, holding the operation piece by hand, and swinging operation (hinge operation) around the folding line By doing so, the composite thin line image and the screen are relatively slid. Variable image display body in which the so that also, as shown in Patent Document 5-8, have already been proposed.

  In the variable image display body having the above-described structure, the displacement of the swing side end portion of the operation piece portion by the hinge operation is greatly reduced to the composite thin line image or the screen support body connected to the operation piece portion. Compared to the case where the composite thin line image or the screen carrier itself is directly moved by hand, the alignment between the composite thin line image and the screen is much more precise. Therefore, it is easy to display only the image to be observed neatly, and even when the composite thin line image and the screen are relatively slid at a low speed, Since it can be slid smoothly, there is an advantage that it is possible to easily display a moving image more smoothly.

  However, in order to increase the number of image change patterns and to display moving images more smoothly, the number of original images is increased while the fineness of the displayed image is reduced in order not to reduce the definition of the displayed image. If you try to make the screen finer, the screen cycle will become finer. In addition to the accuracy of alignment between the composite thin-line image and the screen and the smoothness of relative sliding, there will be problems that greatly affect the quality of the displayed image. Come on. If the composite thin-line image carrier and the screen carrier are not in close contact with each other and a gap is generated between them, even if both are accurately aligned in the horizontal direction, In addition to the fine line image that should originally be seen, a part of the fine line image adjacent to it can be seen together, so that the image that should be observed is not clearly observed and becomes cloudy. It is a problem that it is observed as blurred or blurred.

  As described above, a phenomenon in which a part of adjacent thin line images can be seen together occurs even when the number of original images is small and the screen cycle is wide. In this case, Compared with the thin line image to be seen, the appearance of the thin line image adjacent to the thin line image is relatively small, so that the appearance of the observed image is not significantly affected. However, when the screen period is fine, that is, when the width of the fluoroscopic part of the screen is narrow, the appearance of the fine line image that should be seen is small, so the appearance of the adjacent thin line image becomes relatively large, and observation The effect on the appearance of the image to be displayed becomes large and cannot be ignored.

  The above-described new problem occurs more remarkably in the variable image display body using the hinge mechanism described above than in the case where it is not. In order to slide one carrier of the composite thin line image or the screen with respect to the mount using the hinge mechanism, the operation piece portion in the hinge mechanism is positioned at a certain angle from the horizontal position with respect to the mount. As a result, the carrier of one of the composite thin line images or the screen connected to the operation piece is slid horizontally with respect to the mount and simultaneously lifted in the vertical direction. Therefore, a gap is generated between the other carrier and this can be said to be a structural problem in the variable image display using the hinge mechanism. Of course, even in a normal variable image display body that does not use the hinge mechanism, a gap may be generated between the carrier for the composite thin line image and the carrier for the screen for some reason. The same problem occurs.

  Due to the above circumstances, in a variable image display that displays image changes and moving images by relative sliding between the composite thin line image carrier and the screen carrier, the smooth sliding between the two is hindered. Therefore, there has been a demand for the development of technical means that can effectively prevent the occurrence of a gap between the two and thereby enable clear display of images.

  Hereinafter, specific embodiments of the variable image display of the present invention will be described in detail with reference to the drawings.

<First Embodiment>
The variable image display according to the first embodiment of the present invention includes a composite thin line image carrying sheet 20 (FIG. 1) that also serves as a mount 10, a screen carrying sheet 30 (FIG. 2), and a windowed sheet 40 (FIG. 3). It is comprised from.

  On the surface of the composite thin line image carrying sheet 20, each original image is divided into predetermined thin line image widths based on three kinds of original images respectively representing the characters “A”, “B”, and “C”. From the thin line image, the thin line image based on the original image representing the character “A” is first, fourth, seventh,... For the thin line image based on the original image representing the character “C”, the third, sixth, ninth,... From the left end side. In this manner, the thin line images selected every two lines are arranged in order from the left end side, the first of “A”, the second of “B”, the third of “C”, the fourth of “A”, and “B”. For each of the three types of original images, such as No.5, No.6 of “C”, etc. Fine line images come in the order as it appears every two respectively, the composite fine line image 21 is provided constructed by arranging it adjacent to the other.

Further, at the right end of the mount 10, which is also the composite thin line image carrying sheet 20, the folding mechanism 11 is formed via a folding line 11 formed linearly in the vertical direction in order to constitute a hinge mechanism 50 described later. An operation piece 12 that can swing in a direction perpendicular to the paper surface with the curve 11 as an axis is extended. As the mount 10 to the composite thin line image carrying sheet 20, as in the case of the conventionally known variable image display of the same type, for example, thick paper (basis weight of about 150 to 400 g / m ² ) such as card paper or paperboard, Synthetic paper, plastic sheets (thickness of about 100 to 300 μm), and the like can be used. The composite thin line image 21 can be formed by a conventionally known method such as a normal printing method, an electrophotographic method, or an ink jet method.

  The screen carrying sheet 30 includes a see-through see-through portion 32 having a width equal to the thin line image width, which is a division unit of the composite thin line image 21 described above, and a thin line image width that is smaller than the number of the original images of the thin line image, that is, three times. The non-perspective concealment part 33 having a narrow width, that is, a width equal to twice the thin line image width, is adjacent to each other in the same direction as the arrangement direction of the thin line images constituting the composite thin line image 21 described above, that is, in the left-right direction. Thus, the striped screens 31 are alternately arranged. The screen 31 has a size larger than the size of the image to be displayed, that is, a size that can completely include the contour shape of the image to be displayed inside the contour shape of the screen 31. It is necessary to have As long as this condition is satisfied, the size of the screen 31 is not particularly limited. However, the screen 31 is inserted between the mount 10 and the windowed sheet 40 joined at the top and the ground and is slid in the left-right direction. Therefore, the width in the vertical direction needs to be narrower than the width in the vertical direction of the mount 10 and the sheet 40 with window.

  As in the case of the conventionally known variable image display of the same kind, a screen 31 in which a concealing portion is printed on the surface of a transparent plastic film with an opaque printing ink can be used as the screen 31. The screen carrying sheet 30 may be entirely constituted by the screen 31 or may have a sheet portion other than the screen 31 (whether it is transparent or opaque). In the illustrated example, the screen carrying sheet 30 is connected to an extending portion 34 made of an opaque material similar to that of the mount 10 described above, such as card paper, at a joint portion 35 at the right end portion of the screen 31. The extending portion 34 is provided with a cut line 36, folding lines 37 and 38, and an operation piece portion 39 for constituting a hinge mechanism 50 described later. The folding curve 38 that connects the extended portion 34 and the operation piece portion 39 so as to be foldable is the same as the operation piece portion 12 at the right end of the mount 10 when the screen carrying sheet 30 is placed on the mount 10. The part on the top and bottom of the cut line 36 of the operation piece 12 (this part) is located at a position on the opposite side (right side) to the composite thin line image 21 side with respect to the folding line 11 that is the connecting part of Are also formed at positions that are at the same position as the folding line 11 of the mount 10.

  The windowed sheet 40 is made of the same material as that of the mount 10 described above, such as card paper, and the outer dimensions thereof are not particularly limited, but do not hinder the operation of the hinge mechanism 50 described later. In addition, it is preferable that the dimensions are such as not to cover the bent portions 11, 37, and 38 of the mount 10 and the screen carrying sheet 30 when fixed on the mount 10. The windowed sheet 40 is displayed so that an image displayed by the cooperation of the composite thin line image 21 carried on the composite thin line image carrying sheet 20 and the screen 31 carried on the screen carrying sheet 30 can be observed. A window 41 having a size equal to or larger than the size of the power image, that is, a size that can completely include the shape of the contour of the image to be displayed inside the shape of the contour. Yes. The “image to be displayed” refers to an image of a part intended by the producer to be observed by an observer among images that can be displayed by the cooperation of the composite thin line image 21 and the screen 31. In particular, the composite thin line image 21 may be the whole or a part thereof.

  The sheet 40 with a window in the variable image display body of the present invention further includes a non-window portion 42 in the vicinity of the window portion 41 (a portion other than the window portion 41, that is, a portion where the sheet is present), and a screen carrying sheet. A pressing means 43 that elastically presses the screen carrying sheet 30 is provided on the surface on the side facing the 30. In the illustrated example, the pressing means 43 has a certain width across a contour line 44 of the window 41 and a part of the non-window 42 near the window 41 of the windowed sheet 40. By extending the extended piece 45 with the contour line 44 as a broken line, the elastic repulsive force of the constituent material of the windowed sheet 40 against the return is utilized. Thus, the folded portion (folded piece 46; see FIGS. 4 and 5) serves as the pressing means 43 that elastically presses the screen carrying sheet 30 described above.

In the present invention, the pressing means 43 is not limited to the above-described folded piece 46, and other examples include a string spring, a leaf spring, rubber, a sponge, an air bag (bubble cushioning material), and the like. It is also possible to apply. However, when the pressing means 43 is formed by the folded piece 46 described above, there is an advantage that it can be manufactured easily and inexpensively without adding a special material or a special process. In order to obtain a sufficient pressing effect for the purpose of the present invention by the folded piece 46, it is desirable to use a sheet material that can be bent and has a certain degree of waist as the material of the windowed sheet 40. For example, it is desirable to use paper such as card paper or paperboard having a basis weight of about 150 to 400 g / m ² , synthetic paper or plastic sheet having a thickness of about 100 to 300 μm.

  The screen carrying sheet 30 and the windowed sheet 40 are arranged in this order on the above-described mount 10 (composite thin line image carrying sheet 20), and the mount 10 and the windowed sheet 40 are not separated from each other, and In the meantime, the mount 10 and the windowed sheet 40 are joined (not shown) at the top and bottom so that the screen 31 portion of the screen carrying sheet 30 can slide in the left-right direction. By joining the operation piece part 12 extended to the part via the folding line 11 and the operation piece part 39 connected to the right side of the extension part 34 in the screen carrier sheet 30 via the folding line 38, The variable image display body according to the first embodiment of the present invention is completed (FIG. 4).

  In this variable image display body, a hinge mechanism 50 is formed by folding lines 11, 37, and 38, operation piece portions 12 and 39, and an extending portion 34 provided on the mount 10 and the screen carrying sheet 30 described above. When the operation piece 52 in the hinge mechanism 50 is swung from a state horizontal to the mount 10 (FIG. 6) so that the right end of the operation piece 52 is lifted upward with the folding line 51 as an axis ( 7), the screen carrying sheet 30 on the mount 10 moves slightly to the left due to the hinge action, whereby the screen 31 carried on the screen carrying sheet 30 is moved to the mount 10 (composite thin line image carrying sheet 20). The composite thin line image 21 formed above slides slightly to the left.

  When the sliding distance becomes equal to the width of each thin line image (thin line image width) constituting the composite thin line image 21, the character “A” is displayed instead of the image of the character “A” displayed in the initial state. The image of the character “C” formed by the adjacent thin line images on the left side of the thin line images constituting the image “” is displayed. When the image is further slid by a distance corresponding to the thin line image width, the image of the character “B” is displayed instead of the image of the character “C”. When the image is further slid by a distance corresponding to the width of the thin line image, the character “C” is displayed again. The image “A” is displayed, and this is repeated thereafter. On the other hand, when the right end portion of the operation piece 52 is swung upward from the state where it is lifted upward, the character “B” is changed from the image of the character “A” to the image of the character “B”. The displayed images are sequentially switched from the image to the image of the character “C” and from the image of the character “C” to the image of the character “A”.

  By the way, in the case of the conventional variable image display body in which the pressing means 43 (folding piece 46) is not provided when the right end portion of the operation piece portion 52 is swung upward, the screen carrying sheet 30 is Simultaneously with the movement in the left direction, the portion on the hinge mechanism 50 side is lifted upward, thereby forming the screen 31 portion of the screen carrying sheet 30 and the composite thin line image 21 of the composite thin line image carrying sheet 20 (mounting sheet 10). A gap 60 is generated between the formed portion (FIG. 8). On the other hand, the variable image display body of the present invention is provided with the pressing means 43 (folding piece 46) on the screen carrying sheet 30 side surface of the non-window portion 42 in the vicinity of the window portion 41 of the windowed sheet 40. Since the pressing means 43 (folding piece 46) elastically presses the screen carrier sheet 30 toward the composite thin line image carrier sheet 20 (FIG. 5), in the window part 41 which is a variable image display part, A gap 60 is not generated between the composite thin line image carrying sheet 20 and the screen carrying sheet 30, and a good state in which both are in close contact is maintained (FIG. 7), and a clear image can be displayed. .

  In order to most effectively prevent the generation of the gap 60 between the composite thin line image carrying sheet 20 and the screen carrying sheet 30 in the window 41 which is a variable image display unit, the entire window 41 of the windowed sheet 40 is completely prevented. It is most desirable to provide the pressing means 43 over the circumference. However, the gap 60 between the composite thin line image carrying sheet 20 and the screen carrying sheet 30 is formed on the side of the hinge mechanism 50 due to the undulation in the sliding direction accompanying the relative sliding of the two, and the action of the hinge mechanism 50 described above. Although it often occurs non-uniformly in the sliding direction due to lifting or the like, it is rare that it occurs non-uniformly in the direction orthogonal to the sliding direction. Therefore, the object of the present invention can be substantially achieved if the pressing means 46 is provided on both sides of the top and bottom so as to cover at least the substantially entire length of the variable image display portion in the sliding direction. That is, when the above-described folded piece 46 is used as the pressing means 43, the window portion 41 of the windowed sheet 40 has a relative shape between the composite thin line image carrying sheet 20 and the screen carrying sheet 30 such as a rectangular shape or a shape close thereto. In the case of having two opposite sides that are linear along the sliding direction, the object of the present invention can be substantially achieved by providing the folding piece 46 over almost the entire length of the two sides. it can.

  The variable image display according to the first embodiment of the present invention can be implemented with various modifications in addition to the illustrated one. For example, in the illustrated example, the operation piece 52 is formed to have a narrower width than the mount 10 (the portion on the left side of the folding line 51), but the operation piece 52 and the mount 10 have substantially the same shape and shape. A folded card in which an image is changed and displayed by an opening / closing operation can be obtained. In addition, by binding the folded card-like structure into a booklet so that it becomes a double-page spread, it is possible to obtain a booklet such as a book or a magazine whose image is changed and displayed by opening and closing the page. Furthermore, by preparing a plurality of variable image display bodies having a folded card-like structure and sequentially binding them while joining the back surface of the mount 10 of the adjacent variable image display body and the back surface of the operation piece 52. A picture book may be provided in which each variable page is provided with a variable image display in which an image is changed and displayed by opening and closing the page.

  On the other hand, the operation piece portion 52 remains narrow, and the end (left end portion) opposite to the operation piece portion 52 side of the mount 10 is bound into the booklet body as a binding portion side, whereby a page edge is obtained. It is also possible to use a booklet in which an image is changed and displayed by a swinging operation of the side end. In this case, as shown in the figure, the variable image display body having the operation piece 52 on the right side is arranged on the right side of the double-page spread, and the operation piece 52 is arranged on the left side as a structure symmetrical to that shown in the figure. By binding the variable image display body into the booklet so as to be arranged on the left side of the spread page, a booklet having the variable image display body on both the left and right pages of the spread page can be obtained. Further, in this case, even if another variable image display body having a right / left target structure is pasted back to back on the back side of the variable image display body, each can function as an independent variable image display body. A booklet having a variable image display on both sides can also be used.

  In the variable image display according to the first embodiment of the present invention, the composite thin line image carrying sheet 20 is also used as the mount 10, that is, instead of forming the composite thin line image 21 directly on the mount 10, Alternatively, a composite thin line image 21 may be formed on a separate composite thin line image carrying sheet 20 and inserted between the mount 10 and the screen carrying sheet 30 and fixed on the mount 10. . In this way, by preparing a plurality of types of composite thin line image carrying sheets 20 and replacing them as necessary, it is possible to display more types of images using one variable image display. It is possible to increase the types of image change patterns or moving images that can be displayed.

  Moreover, the illustrated composite thin line image 21 and the screen 31 are schematic examples to the point of being tired, and the present invention is not limited thereto. The type of the original image constituting the composite thin line image 21 is not particularly limited. In addition to characters and symbols, for example, characters such as people, animals and plants, comics or animation, vehicles, robots and other machinery, landscapes, abstract paintings, etc. Images that represent any object such as a combination of multiple types can be used, and a moving image can be expressed by using multiple original images that represent the situation in which the object sequentially transitions over time You can also The number of original images to be used is not particularly limited. Technically, the number of original images can be up to about ten. However, if the number is too large, the number of the original images is concealed by the concealing unit 33 of the screen 31 occupying the area of the displayed image. Since the ratio of the area of the portion to be displayed becomes high and the displayed image becomes unclear and difficult to observe, the number of original images is preferably in the range of about 2 to 6. In addition, even if the fine line image width is too narrow, the displayed image becomes unclear. On the other hand, if the fine line image width is too wide and the repetition period is too long, the displayed image is too coarse to be recognized as an image. Therefore, assuming that the observer observes the variable image display body of the present invention while holding it by hand, the fine line image width is about 0.2 to 1 mm, more preferably about 0.3 to 0.6 mm. It is desirable to design the repetition period to be approximately in the range of about 0.5 to 5 mm, more preferably about 1 to 3 mm.

  Further, the concealing unit 33 in the screen 31 passes through the thin line image and the concealing unit 33 observed through the see-through unit 32 of the screen 31 when the composite thin line image 21 is observed through the screen 31. It is sufficient that the thin line image to be observed is observed with sufficient contrast so that the image is substantially concealed so that the observer can recognize an image composed only of the former thin line image. To this extent, it is not always necessary to be completely light-impermeable. That is, in the present invention, the fact that the concealing portion 33 is “not transparent” does not necessarily mean that the optical portion is not completely transparent, and can be said to be substantially impossible to see in comparison with the transparent portion 32. In general, the light transmittance of the concealing portion 33 is approximately 1/5 or less, more preferably 10 minutes, of the light transmittance of the see-through portion 32. It may be about 1 or less. There is no particular limitation on the color of the concealing unit 33, and it is generally desirable that the color is an achromatic color such as black, white, or gray. However, depending on the type of image, a chromatic color such as red, blue, or green is also used. Sometimes you can. Further, the concealing unit 33 is chromatically transparent, that is, a color that conceals only light in a specific wavelength range and transmits light in other wavelength ranges, so that a specific color component in the colors constituting the composite thin line image 21 is obtained. It is also possible to provide a variable image display body that has a variable image display effect only for, and always displays other color components.

  Furthermore, in the illustrated example, the fine line image constituting the composite thin line image 21 and the shape of the thin lines such as the see-through part 32 and the concealing part 33 constituting the screen 31 are the composite thin line image carrying sheet 20 and the screen carrying sheet 30. However, the present invention is not limited to this, for example, at a certain angle that is neither parallel nor perpendicular to the sliding direction. Crossing diagonal planes, arcs, "", "" zigzag ", sinusoidal, and other wavy lines, etc. Any shape is possible as long as it is possible. However, the uniformity of the image quality of the image displayed by the cooperation of the composite thin line image 21 and the screen 31, the ease of manufacturing the composite thin line image 21 and the screen 31, and the composite thin line image support when the variable image display is assembled. Considering the ease of alignment between the sheet 20 and the screen carrying sheet 30 and the like, it is most desirable that the shape of the thin line is a straight line (including a diagonal line).

<Second Embodiment>
In the variable image display according to the first embodiment of the present invention described above, the operation piece 52 in the hinge mechanism 50 has its end opposite to the mount 10 side upward from a horizontal position with respect to the mount 10. In this hinge mechanism 50, the folding line 51 (11, 37) between the mount 10 and the operation piece 52, the extending portion 34 of the screen carrying sheet 30, and the like are lifted. By reversing the positional relationship in the sliding direction (left-right direction) with the folding line 38 between the operation piece 39 and the operation piece 39, the operation piece 52 is swung in a direction that pushes it downward. You can also. That is, as shown in FIG. 9, the mount 10 (composite thin line image carrying sheet 20) moved to the right along the folding line 11 from that shown in FIG. 1, and as shown in FIG. The folding line 37 is moved to the right side and the folding line 38 is moved to the left side, and the same as that in the first embodiment of the present invention described above, for example, as shown in FIG. By using the windowed sheet 40 similar to the one, a variable image display body according to the second embodiment of the present invention as shown in FIG. 11 can be obtained.

  In the variable image display body having the hinge mechanism 50 having such a structure, when the operation piece 52 of the hinge mechanism 50 is swung down so as to be lowered, the screen 31 carried on the screen carrying sheet 30 is Since the sheet 10 slides slightly to the right with respect to the mount 10 (composite thin line image carrying sheet 20), the image displayed on the window 41 is an image of the letter “B” from the original letter “A”. The image is repeatedly switched in the order of the image of the character “C” and then the image of the character “A” again. Then, when the operation piece portion 52 is swung in a direction to return to the original horizontal position from the state where the operation piece portion 52 is pushed down, the displayed images are sequentially switched in the reverse order.

  Even in the variable image display body having the hinge mechanism 50 having such a structure, in the case of a conventional variable image display body in which the pressing means 43 (folding piece 46) is not provided, the right end portion of the operation piece portion 52 is provided. When the screen carrying sheet 30 is slid so as to be pushed downward, simultaneously with the sliding in the right direction, the portion on the hinge mechanism 50 side is lifted upward so that the screen 31 of the screen carrying sheet 30 A gap 60 is generated between the portion and the portion where the composite thin line image 21 of the composite thin line image carrying sheet 20 (mounting sheet 10) is formed (FIG. 13). On the other hand, the variable image display body of the present invention is provided with the pressing means 43 (folding piece 46) on the screen carrying sheet 30 side surface of the non-window portion 42 in the vicinity of the window portion 41 of the windowed sheet 40. Since the pressing means 43 (folding piece 46) elastically presses the screen carrying sheet 30 toward the composite thin line image carrying sheet 20, the composite thin line image carrying is carried out in the window 41 which is a variable image display unit. A gap 60 is not generated between the sheet 20 and the screen carrying sheet 30, and a good state in which both are in close contact is maintained (FIG. 12), so that a clear image can be displayed.

  The variable image display according to the second embodiment of the present invention can be implemented with various modifications in addition to the illustrated one. However, unlike the case of the variable image display body of the first embodiment described above, it is impossible to fold the mount 10 and the operation piece 52 with the variable image display portion inside, and on the opposite side. Even when folded and closed, a part of the extended portion 34 of the screen carrying sheet 30 protrudes from the end of the mount 10 on the folding curve 51 side, so that the image is changed and displayed by the opening / closing operation. It is not suitable for use as a two-fold card or a booklet in which an image is changed and displayed by opening and closing a page. In addition, when the variable image display bodies having a symmetrical structure are pasted back to back, the operation pieces 52 of the variable image display bodies on the front and back sides interfere with each other so that the swing operation cannot be performed. It is also unsuitable for use as a structure having a variable image display on both sides. However, the variable image display according to the second embodiment can be bound into the booklet with the end opposite to the operation piece 52 of the mount 10 as the binding portion, and the left and right A variable image display body having the same structure which is not symmetrical is pasted back to back in a positional relationship where each operation piece 52 does not overlap the other mount 10 and used as a single structure having a variable image display body on both the front and back sides. It is also possible to do.

<Third Embodiment>
In the variable image display of the present invention, in order to make the composite thin line image carrying sheet 20 and the screen carrying sheet 30 slide relative to each other, the composite thin line image carrying is carried out as in the first and second embodiments described above. Instead of fixing the position of the sheet 20 and moving the screen carrying sheet 30, it is also possible to adopt a structure in which the position of the screen carrying sheet 30 is fixed and the composite thin line image carrying sheet 20 is moved instead. is there. The variable image display body according to the third embodiment of the present invention, which is an example of the variable image display body having such a structure, includes a mount 10 (FIG. 14) and a composite thin line image carrying sheet 20 (FIG. 14) separate from the mount 10 (FIG. 14). 15), a screen carrying sheet (FIG. 16), and a windowed sheet 40 (FIG. 3).

  The mount 10 (FIG. 14) in the variable image display body of the third embodiment has the same structure as the mount 10 (FIG. 1) in the variable image display body of the first embodiment described above. The composite thin line image 21 is not formed on the surface. Instead, the composite thin line image carrying sheet 20 (FIG. 15) having a structure similar to the screen carrying sheet 30 (FIG. 2) in the variable image display of the first embodiment described above, which is separate from the mount 10. A composite thin line image 21 is formed on the surface. On the other hand, the screen support sheet 30 (FIG. 16) is not provided with the extending portion 34, the cut line 36, the folding lines 37 and 38, and the operation piece 39 for forming the hinge structure 50 later. The outer dimension is formed so that the whole fits within the range of the outer dimension of the windowed sheet 40. The screen carrier sheet 30 is entirely constituted by a screen 31. In this embodiment, the screen carrier sheet 30 does not slide with respect to the windowed sheet 40, and therefore is a part that is detached from the window frame 41. May be made of a sheet material other than the screen 31. The windowed sheet 40 (FIG. 3) is the same as that in the variable image display of the first embodiment described above.

  Then, the composite thin line image carrying sheet 20, the screen carrying sheet 30, and the windowed sheet 40 are arranged in this order on the above-described mount 10, and thereafter, the variable image display of the above-described first embodiment is performed. In the same manner as in the case of the body, except that the operation piece 12 connected to the mount 10 has a folding line 24 formed on the composite thin line image carrying sheet 20 instead of the operation piece 39 connected to the screen carrying sheet 30. By joining the operation piece portions 25 that are connected to each other, the variable image display body according to the third embodiment of the present invention is completed (FIG. 17).

  The variable image display according to the third embodiment of the present invention lifts the operation piece 52 of the hinge mechanism 50 upward, as in the case of the variable image display according to the first embodiment of the present invention described above. The image displayed on the window portion 41 can be changed by swinging in any direction. However, in this case, it is not the screen carrier sheet 30 but the composite thin line image carrier sheet 20 that slides in the left direction by the swinging operation. This is the reverse of the case of the variable image display of the first embodiment of the invention. That is, when the operation piece 52 is swung in a direction that lifts upward, the image displayed on the window 41 is changed from the original image of the character “A” to the image of the character “B”, and further to the character “C”. ”And then to the image of the letter“ A ”again in order, and when the operation piece 52 is swung in a direction to return it to the original horizontal position from the state where it is lifted upward, it is displayed. The images to be switched are sequentially switched in the reverse order.

  Even in the variable image display body having the hinge mechanism 50 having such a structure, in the case of a conventional variable image display body in which the pressing means 43 (folding piece 46) is not provided, the right end portion of the operation piece portion 52 is provided. When the composite thin line image carrying sheet 20 is slid so as to be lifted upward, the hinge mechanism 50 side portion is lifted upward simultaneously with the sliding in the left direction. However, the screen carrying sheet 30 is deformed so as to be convexly curved downward, while the screen carrying sheet 30 is maintained in a substantially planar state without receiving a force that causes the entire screen to bend. Is lifted upward by the composite thin line image carrying sheet 20, so that the screen carrying sheet 30 as a whole is lifted from the surface of the composite thin line image carrying sheet 20, or For a difference in bending state between the sheet 30 and the composite image carrying sheet 20 occurs, a gap 60 is generated between them (Figure 20).

  On the other hand, in the variable image display of the third embodiment of the present invention, the screen carrying sheet 30 is provided on the screen carrying sheet 30 side surface of the non-window portion 42 in the vicinity of the window portion 41 of the windowed sheet 40. Pressing means 43 (folding piece 46) that elastically presses the image toward the composite thin line image carrying sheet 20, and the pressing means 43 places the screen carrying sheet 30 and the composite thin line image carrying sheet 20 together on the mount 10. 18 (FIG. 18), the window 41 serving as the variable image display unit does not generate a gap 60 between the composite thin line image carrying sheet 20 and the screen carrying sheet 30. Is kept in a good state (FIG. 19), and a clear image can be displayed.

  The variable image display according to the third embodiment of the present invention is also not very practical if it is technically impossible to replace the composite thin line image 21 carried on the composite thin line image carrying sheet 20. For example, as in the case of the variable image display of the first embodiment described above, the aspect can be variously changed. In addition, the hinge mechanism 50 in the variable image display according to the third embodiment of the present invention can be replaced with a mechanism similar to that in the variable image display according to the second embodiment described above. The range in which the embodiment can be changed in this case is substantially the same as that of the variable image display of the second embodiment described above.

  In the variable image display according to the third embodiment of the present invention, the composite thin line image carrying sheet 20 is also relative to the windowed sheet 40 by the swinging operation of the operation piece 52 of the hinge mechanism 50. Therefore, when the distance that the composite thin line image carrying sheet 20 can slide by the swinging operation of the operation piece 52 exceeds the period of the screen 31, the composite thin line image 21 and the screen 31 are moved. Images appearing in cooperation can appear at two or more different positions depending on the swing position of the operation piece 52. Further, if the distance that the composite thin line image carrying sheet 20 can slide is several times the period of the screen 31 or more, the composite thin line image 21 and the screen 31 cooperate with each other based on the same original image. Part of the image that appears is outside the window portion 41 of the windowed sheet 40 and is not displayed in some cases due to the swinging position of the operation piece 52. The portion displayed in the window portion 41 of the image based on the same original image can be sequentially changed along the sliding direction of the composite thin line image carrying sheet 20. In this case, the size of the window 41 is such that when the operation piece 52 is in one swing position among the images that can be displayed by the cooperation of the composite thin line image 21 and the screen 31, that is, the composite thin line image carrying sheet. What is necessary is just to set it as the dimension which can contain at least the shape of the image of the part which the producer intended to have an observer observe when 20 exists in one sliding position.

<Fourth Embodiment>
In the variable image display of the present invention, it is also possible to use the windowed sheet 40 as it is as a member for covering the variable image display part. In this case, the surface of the non-window part 42 of the windowed sheet 40 is used. Alternatively, it is possible to form an arbitrary pattern related to or unrelated to the image displayed on the window 41 that is the variable image display unit. However, the variable image display body of the present invention is not limited to such a structure, and on the sheet 40 with a window, as a separate member for the cover, similarly to the sheet 40 with a window. It is also possible to provide a cover sheet 70 with a window made of a sheet body in which a window 71 for allowing the variable image display unit to be observed. In this case, if a design for the cover is required, it may be provided on the cover sheet 70 with a window, and it is not necessary to provide a pattern on the sheet 40 with a window.

  What is shown in FIG. 22 is a book in which the cover sheet with window 70 shown in FIG. 21 is provided on the window sheet 40 of the variable image display body of the third embodiment of the invention shown in FIG. It is an example of the variable image display body of the 4th Embodiment of invention. Of course, the variable image display of the fourth embodiment of the present invention is not limited to this, and the variable image display of the first embodiment of the present invention shown in FIG. 4 and the variable image display shown in FIG. On the basis of the variable image display body according to the second embodiment of the present invention, or the variable image display body according to an embodiment obtained by further appropriately modifying them, an appropriate cover sheet with window 70 is provided on the window sheet 40. Can be configured.

  The cover sheet 70 with a window can be formed from the same material as the sheet 40 with a window, and the size of the window 71 is the same as that of the window 41 of the sheet 40 with a composite thin line image. The image displayed by the cooperation of the composite thin line image 21 carried on the sheet 20 and the screen 31 carried on the screen carrying sheet 30 can be observed at least equal to or larger than the size of the image to be displayed. On the other hand, in order to prevent a portion of the non-window portion 42 of the window sheet 40 below from being seen near the outline of the window portion 71 and making it unsightly, The dimension equal to or smaller than the dimension of the window portion 41, that is, the contour shape of the window portion 71 of the cover sheet 70 with window may be completely included in the contour shape of the window portion 41 of the window sheet 40. like It is desirable that the law. It is not necessary to provide the pressing means 43 such as the folded piece 46 as in the case of the windowed sheet 40 described above on the cover sheet with window 70.

  Various cases are conceivable as technical reasons for providing the windowed cover sheet 70 on the windowed sheet 40 as described above. For example, when the pressing means 43 in the variable image display body of the present invention is constituted by the folded piece 46 of the windowed sheet 40, the elastic repulsive force that is the basis of the pressing force is the thickness of the material constituting the windowed sheet 40. And the elastic modulus (rigidity) and the like. Generally, the thicker the thickness, the stronger the pressing force. On the other hand, since the surface mounting member of the variable image display body of the present invention is required to have sufficient durability against friction during use, it is desirable to use a sheet having a certain thickness. Therefore, if a sheet having a sufficient thickness is employed, the pressing force as the pressing means 43, that is, the elastic repulsive force of the folded piece 46 becomes too strong, and the relative relationship between the composite thin line image bearing sheet 20 and the screen bearing sheet 30 is increased. May interfere with general sliding. In such a case, the function of the cover member is assigned to the cover sheet 70 with a window separate from the window sheet 40, and a sheet having a sufficient thickness is used for this. By adopting a sheet having an appropriate thickness for generating an appropriate pressing force as the pressing means 43, the sheet 40 has the strength and durability of the member for covering and the appropriate pressing force of the pressing means 43. There is an advantage that both can be easily achieved.

  Further, as in the case of the variable image display of the fourth embodiment of the present invention shown in FIG. 22, when the structure in which the screen carrying sheet 30 is fixed and the composite thin line image carrying sheet 20 is slid is adopted, the sliding The screen carrying sheet 30 is fixed to the mount 10 or the windowed sheet 40 so that the screen carrying sheet 30 is not moved by the composite thin line image carrying sheet 20. It is desirable to adopt the latter structure so that the composite thin-line image carrying sheet 20 does not hinder sliding on the mount 10, and in this case, the window of the windowed sheet 40 is used. In the vicinity of the portion 41, the pressing means 43 (folded piece 46) provided on the windowed sheet 40 acts to keep the screen carrying sheet 30 away from the windowed sheet 40. Therefore, the surface of the windowed sheet 40 does not become flat and is inclined in a certain direction (in particular, when the screen carrying sheet 30 is fixed to the windowed sheet 40 only on one side of the window portion 41 of the windowed sheet 40) 23, or curved so as to swell like a drum (particularly when the screen carrying sheet 30 is fixed to the windowed sheet 40 on both sides of the window 41 of the windowed sheet 40). See). Even in such a case, by providing the windowed sheet 70 with a separate window on the windowed sheet 40, the windowed sheet 70 is flat when the windowed sheet 40 is inclined or curved. This has the advantage that it is possible to maintain a good appearance.

  The variable image display body according to the fourth embodiment of the present invention is also variously modified in the same manner as in the case of the variable image display body according to each of the embodiments described above in which the cover sheet with window 70 is omitted. Can be implemented.

<Fifth Embodiment>
In each of the variable image displays of the embodiments of the present invention described above, the mount 10, the composite thin line image carrying sheet 20, the screen carrying sheet 30, the windowed sheet 40 and the windowed cover sheet 50 are included in the present invention. Except that the mount 10 also serves as a composite thin line image carrying sheet in the first and second embodiments, each was constituted by a separate sheet, but the present invention is not limited to this, Any number of sheets selected from these sheets may be composed of one blank sheet connected to each other.

  FIG. 24 shows an example of a development view of the blank sheet. The mount 10, the composite thin line image carrying sheet 20, and the windowed sheet 40 (the folded pieces 46 provided along the top and bottom sides of the window 41 are shown in FIG. The cover sheet 70 with a window and the cover sheet 70 with a window is composed of a single blank sheet connected to each other. Then, the screen 31 (partially cut out and displayed in FIG. 24) is placed on the upper surface side of the windowed sheet 40, and at the top and bottom ends of the window 41 of the windowed sheet 40. After fixing the screen 31 to the windowed sheet 40 by fitting, fitting or any other appropriate method, the windowed sheet 40 to which the screen 31 is fixed is opened by a folding line 73 between the windowed sheet 70 and the windowed sheet 70. On the other hand, the composite thin line image carrying sheet 20 is folded back to the back side of the mount 10 along the folding line 13 between the mount sheet 10 and the operation piece 12 connected to the mount 10 and the composite thin line. The operation piece 25 connected to the image carrying sheet 20 is joined to the back surface thereof, and then the mount 10 and the composite thin line image display sheet 20 are placed between the mount 10 and the cover sheet 70 with a window. It is folded back to the back side of the cover sheet with window 70 by the folding line 14, and the ends of the open side opposite to the folding line 14 of the backing sheet 10 and the window mounting sheet 70 are bonded, fixed by fitting or other appropriate methods. Then, the variable image display body according to the fifth embodiment of the present invention is completed.

  According to the structure of this development view, the printing of the cover pattern on the surface of the cover sheet with window 70 and the printing of the composite thin line image 21 on the surface of the composite thin line image carrying sheet 20 are performed on the same surface of the same sheet material. In addition, since each sheet (excluding the screen carrying sheet 30) constituting the variable image display body is formed by punching and bending one sheet material, the manufacturing is simple, There is an advantage that the variable image display of the present invention can be easily manufactured without requiring any special device for alignment when assembling the sheet.

  The variable image display body according to the fifth embodiment of the present invention can be implemented with various modifications as in the case of the variable image display bodies according to the respective embodiments described above. For example, on the left side or the lower side of the cover sheet with window 70 in the developed view shown in FIG. 24, or on the left side or the upper side of the mount 10, the same size as the cover sheet with window 70 or the mount 10, or the cover sheet with window 70. Further, by connecting the cover pieces that are the same size as the shape of the operation piece portion 12 to the mount 10 so as to be bendable, the variable image display portion can be covered or exposed by opening and closing the cover 2. A foldable card-like variable image display can be obtained. Further, instead of the cover piece, the window cover sheet or the right end side of the mount in another variable image display body symmetrical with the entire variable image display body is used as the window cover sheet in the variable image display body. By connecting to the left end of 70 or the mount 10 so as to be foldable, an openable and foldable card-like variable image display body having variable image display bodies on both the left and right sides in an open state can be obtained. Furthermore, such a variable image display body is bound as a part of a booklet, or a plurality of the above-described two-fold card-like variable image display bodies are prepared, and the back surfaces of adjacent variable image display bodies are joined to each other. However, it is also possible to obtain a picture book in which a variable image display is provided on each spread page by sequentially binding.
