Abstract

PROBLEM TO BE SOLVED: To provide a variable image display body in which a clear image can be displayed by continuously making a carrier of composite fine line images and a screen carrier stick together, and which can prevent clogging of foreign substances in a gap and deterioration of appearance by decreasing a step between a surface of the screen carrier and a surface of a sheet with window to be placed on the screen carrier, in the variable image display body due to relative sliding of the composite fine line images and a stripe-like screen.SOLUTION: A composite fine line image carrier sheet 20 and a screen carrier sheet 30 are arranged on a pasteboard 10 so as to be relatively slidable. The sheet 40 with window is arranged thereon. Pressing means 15 for elastically pressing the composite fine line image carrier sheet 20 and the screen carrier sheet 30 toward the sheet 40 with window is arranged on the pasteboard 10.

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. For example, Patent Document 1 discloses a variable image display body that is displayed so that an image displayed on a display unit changes into a completely different image instantaneously by sliding, or is displayed as a moving image that continuously changes. As is shown in -6, it is well known to moths. 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 2 to 5, 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 orthogonal to the sliding direction is provided at one end of the relative sliding direction of 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 7 and 15, 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.

  Therefore, in view of such problems, the present inventors have already extended from the outline of the window portion to the inner side of the window on the lower surface in the vicinity of the window portion of the windowed sheet placed on the carrier of the screen. A folded piece is formed by folding the set piece downward with the outline as a broken line, and the carrier of the screen is elastically pressed toward the carrier of the composite fine line image by the folded piece, thereby supporting the composite fine line image. A variable image display body has been proposed that prevents the occurrence of a gap between the body and the screen carrier and always displays an image clearly (Patent Document 16).

  However, in the variable image display body having the above-described structure, a level difference of at least two sheets or more is inevitably generated between the surface of the windowed sheet and the surface of the screen carrier. Therefore, a foreign object may be caught in the gap caused by the step to reduce the appearance, and in the case of a booklet such as a picture book using the variable image display body, the screen carrier or the surface of the adjacent page is not covered when the page is opened or closed. It may be hurt. In addition, when a ridge is sandwiched between pages, the tip of the ridge is sandwiched between the window sheet and the screen carrier, and the operability when opening the page is reduced. In some cases, the screen carrier may be damaged. Furthermore, when a pattern related to the image displayed by the variable image display is formed on the surface of the windowed sheet, the pattern displayed on the surface of the windowed sheet is displayed between the image displayed on the variable image display. Since the level difference of at least two sheets (including the windowed sheet itself) is inevitably generated, the latter is clearly seen as a recess with respect to the former, or when viewed from an oblique direction, it is horizontal between the two. There is a problem that the sense of unity between the two is hindered due to the misalignment of the direction, and the overall interest may be diminished.

  Due to the above circumstances, in a variable image display that displays a change in image or a moving image by relative sliding between the composite thin line image carrier and the screen carrier, the two images are always kept in close contact with each other so that the image is clear. Development of technical means that can display and reduce the level difference between the surface of the screen carrier and the surface of the windowed sheet placed on it, and reduce the contamination of foreign objects and the deterioration of appearance. Was requested.

  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 mount 10 (FIG. 1), a composite thin line image carrying sheet 20 (FIG. 2), a screen carrying sheet 30 (FIG. 3), and a windowed sheet 40 ( 4).

  As the mount 10, for example, thick paper such as card paper or paperboard, synthetic paper, plastic sheet, or the like can be used as in the case of the conventionally known variable image display of the same type. In order to constitute a hinge mechanism 50 to be described later, a fold line 11 formed linearly in the vertical direction is formed at the right end portion of the mount 10, and the fold line 11 is used as an axis in a direction perpendicular to the paper surface. A swingable operation piece 12 is extended.

  Further, the mount 10 in the variable image display body of the present invention further includes dimensions of the window portion 41 in the vertical direction so as to be substantially along the left and right vertical sides of the region corresponding to the window portion 41 of the windowed sheet 40 described later. And a cut line 14 connecting the top and bottom ends of the folding line 13 so as to form an isosceles trapezoidal shape having the folding line 13 as a base along with the folding line 13. Folded pieces 15 surrounded by are provided. The folded piece 15 is folded on the surface of the mount 10 by a fold line 13, thereby utilizing the elastic repulsive force of the constituent material of the mount 10 against the folded, and a composite thin line image carrying sheet 20 and a screen described later. The pressing means 16 is configured to elastically press the carrier sheet 30 toward the windowed sheet 40.

In the present invention, the pressing means 16 is not limited to the folded piece 15 described above. For example, a string spring, a leaf spring, rubber, a sponge, an air bag (bubble cushioning material), etc. It is also possible to apply. However, when the pressing means 16 is formed by the folded piece 15 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 15, it is desirable to use a sheet material that can be bent and has a certain degree of stiffness as the material of the mount 10, 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.

  Further, in the illustrated example, the pressing means 16 has a longitudinal direction (extending direction of the folding line 13) in the vertical direction of the mount 10, that is, a relative relationship between the composite thin line image carrying sheet 20 and the screen carrying sheet 30 described later. Although provided so as to extend in a direction orthogonal to the sliding direction, the present invention is not limited to this, and an effective display area of the variable image display body of the present invention, that is, a windowed sheet 40 to be described later. In the area corresponding to the window portion 41, it is only necessary that the composite thin line image carrying sheet 20 and the screen carrying sheet 30 can be uniformly pressed toward the windowed sheet 40. When the pressing means 16 is formed by folding the folded piece 15 formed on the mount 10 as in the illustrated example, a plurality of the pressing means 16 are mutually connected so that the longitudinal direction thereof is perpendicular or parallel to the sliding direction. It is desirable to provide them in parallel. In particular, it is most desirable to provide two in parallel along the vertical or horizontal side of the region.

  The composite thin line image carrying sheet 20 is made of the same material as that of the mount 10 described above, such as card paper, for example, and the characters “A”, “B”, and “C” are represented on the surface thereof, respectively. From the thin line image obtained by dividing each original image into a predetermined thin line image width based on the three kinds of original images, the thin line image based on the original image representing the character “A” is first, fourth, 7 from the left end side. As for the thin line image based on the original image representing the character “B”, the second, fifth, eighth,... From the left end side, the original image representing the character “C”. For the thin line image based on, the thin line images selected every second line, such as the third, sixth, ninth,... From the left end side, in order from the left end side, the first of “A”, “B” , Second of "C", fourth of "A", "B No.5, No.6 of "C", etc., arranged so that they are adjacent to each other in such an order that every two thin line images from each of the three types of original images appear. The composite thin line image 21 is provided.

  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. Further, a cut line 22, folding lines 23 and 24, and an operation piece 25 for constituting a hinge mechanism 50 described later are provided at the right end of the composite thin line image carrying sheet 20, and this operation is performed. The piece 25 is formed to be swingable in a direction perpendicular to the paper surface with the folding line 24 as an axis. The left part of the folding line 24 of the composite thin line image carrying sheet 30 is inserted between the mount 10 and the window sheet 40 joined together at the top and the ground together with the screen carrying sheet 30 to be described later. Since it is slid in the direction, the width in the vertical direction needs to be narrower than the width in the vertical direction of the mount 10 and the windowed sheet 40. Furthermore, as will be described later, when the screen carrying sheet 30 is bonded to the mount 10 at the portions near both ends in the vertical direction, the width in the vertical direction of the left portion from the folding line 24 of the composite thin line image carrying sheet 30 is The screen support sheet 30 needs to be formed narrower than the vertical width.

  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 carrying sheet 30 is not particularly limited, but is inserted between the mount 10 and the windowed sheet 40 joined at the top and the ground. The width in the direction needs to be formed narrower than the width in the vertical direction of the mount 10 and the windowed sheet 40.

  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). Further, when the composite thin line image carrying sheet 20 slides with respect to the mount 10, the screen carrying sheet 30 is fixed to the front surface of the mount 10 or the back surface of the windowed sheet 40. In the illustrated example, a joining portion 34 for joining to the surface of the mount 10 is provided on the back surface of the blank portion provided in the vicinity of both ends of the screen carrying sheet 30 in the vertical direction.

  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 that the folded portions 11, 23, and 24 of the mount 10 and the composite thin line image carrying sheet 20 are not covered 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. Joint portions 42 for joining to the mount 10 are provided at both ends of the windowed sheet 40 in the vertical direction. Furthermore, on the surface of the windowed sheet 40, an arbitrary pattern related to or unrelated to the image displayed in the window 41 can be formed by a printing method or the like by the mechanism of the variable image display body of the present invention. .

  The folding piece 15 of the mount 10 is folded back on the surface of the mount 10 by the folding line 13 to form the pressing means 16, and the composite thin line image carrying sheet 20, the screen carrying sheet 30, the window on the mount 10. The attached sheet 40 is arranged in this order, so that the mount 10 and the screen carrying sheet 30 are not separated, and the composite thin line image carrying sheet 20 can slide in the horizontal direction between them. 30 is joined to the surface of the mount 10 by the joint portions 34 provided in the vicinity of both ends in the vertical direction on the back surface, and both of the mount 10 and the windowed sheet 40 are separated from each other so that the mount 10 and the windowed sheet 40 are not separated from each other. The operation piece portion 12 joined at the joining portion 42 provided at both ends of the top and bottom direction, and further extended to the right end portion of the mount 10 via the folding line 11, and the composite thin wire The variable image display body according to the first embodiment of the present invention is completed by joining the operation piece portion 24 connected to the right end portion of the image carrying sheet 20 via the folding line 24 (FIG. 5). . It should be noted that if the hole of the trace of the folded piece 15 is left open on the back surface of the mount 10, the appearance is unsightly, and foreign matter may enter from this hole and cause a failure. When used in applications where there is a particular concern, the hole may be concealed by covering the back surface of the mount 10 with a separate cover sheet (not shown).

  In this variable image display body, a hinge mechanism 50 is formed by folding lines 11, 23, 24 and operation pieces 12, 25 provided on the mount 10 and the composite thin line image carrying sheet 20 described above. When the operation piece 52 in the hinge mechanism 50 is swung from the horizontal state with respect to the mount 10 so as to lift the right end of the operation piece 52 upward with the folding line 51 as an axis (FIG. 6), The composite thin line image carrying sheet 20 on the mount 10 is slightly moved leftward by the hinge action, whereby the composite thin line image 21 carried on the composite thin line image carrying sheet 20 is screened on the mount 10. The screen 31 is slightly slid leftward with respect to the screen 31 carried on the carrying sheet 30.

  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 letter “B” constituted by the adjacent thin line images on the right side of the thin line images constituting the image “” is displayed. When the image is further slid by the distance corresponding to the thin line image width, the image of the character “C” is displayed instead of the image of the character “B”. When the image is further slid by the distance corresponding to the thin line image width, the character “B” is displayed again. The image “A” is displayed, and this is repeated thereafter. On the other hand, if the right end portion of the operation piece 52 is swung upward from the lifted state, the character “C” is changed from the image of the character “A” to the image of the character “C”. The displayed images are sequentially switched from the image to the image of the character “B” and from the image of the character “B” 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 16 (folded piece 15) is not provided when the right end portion of the operation piece 52 is swung upward, the composite thin line image carrying sheet. At the same time as sliding to the left, 20 is lifted upward on the hinge mechanism 50 side, and as a result, it is deformed so as to be convexly curved slightly downward as a whole. The sheet 30 is lifted upward by the composite thin line image carrying sheet 20 while the end of the operation piece 52 side is lifted upward while maintaining a substantially flat state without receiving a stress that causes the entire sheet to be curved. The carrier sheet 30 as a whole floats from the surface of the composite thin line image carrier sheet 20, or the curved state of the screen carrier sheet 30 and the composite thin line image carrier sheet 20 The difference is generated, a gap 60 is generated between them (Figure 7).

  On the other hand, the variable image display of the present invention is provided with pressing means 16 (folded piece 15) on the surface of the mount 10, and this pressing means 16 (folded piece 15) is the composite thin line image carrying sheet. 20 and the screen carrying sheet 30 are elastically pressed toward the windowed sheet 40, so that a gap 60 is provided between the composite thin line image carrying sheet 20 and the screen carrying sheet 30 in the window 41 that is a variable image display unit. Is not generated, and a good state in which both are in close contact with each other can be maintained, so that a clear image can be displayed (FIG. 6). In addition, the extended support piece which has already been proposed by the present inventors and extends from the contour line of the window portion 41 of the windowed sheet 40 to the inside of the window is folded downward with the contour line as a broken line, and the screen carrier is composite thin wire. A variable image display body (Patent Document 16) serving as a pressing means that elastically presses the image bearing body toward the image bearing body is the same as that of the present invention with respect to ensuring the close contact between the composite thin-line image bearing sheet 20 and the screen bearing sheet 30. Although almost the same effect can be obtained, a step exceeding two sheets of paper is inevitably generated between the surface of the windowed sheet 40 and the surface of the screen carrying sheet 30, so foreign matter is caught in this step. The appearance of the window portion 41 is reduced, or when the pattern associated with the display image by the variable image display is formed on the surface of the windowed sheet 40, the pattern may be discontinuous in the outline of the window portion 41. There is a case for or remember. On the other hand, in the variable image display body of the present invention, the surface of the screen carrying sheet 20 is always pressed against and closely adhered to the back surface of the windowed sheet 40 by the pressing means 16, and therefore the step between the surfaces of both is Since it is minimized to one sheet of paper (sheet 40 with a window), there is an advantage that the above-described deterioration in appearance due to the inclusion of foreign matter and the sense of discomfort due to discontinuity of the pattern can be minimized.

  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.

  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).

  In the variable image display body configured to slide the composite thin line image carrying sheet 20 as described above, the composite thin line image carrying sheet 20 is moved to the windowed sheet 40 by the swinging operation of the operation piece 52 of the hinge mechanism 50. In contrast, since the sliding movement of the operation piece 52 causes the slidable distance of the composite thin line image carrying sheet 20 to exceed the period of the screen 31, the composite thin line image 21 is slid relative to the screen. The images appearing in cooperation with the screen 31 can appear at two or more positions that differ 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.

<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 mechanism 51 (11, 23) between the mount 10 and the operation piece 52 and the main body ( By reversing the positional relationship in the sliding direction (left-right direction) between the folding line 24 between the portion carrying the composite thin line image 21 and the operation piece portion 25, the operation piece portion 52 is lowered downward. It is also possible to have a structure that swings in the direction of pushing down. That is, as shown in FIG. 8, the mount 10 has moved the folding line 11 to the right than the one shown in FIG. 1, and the folding line 23 is moved to the right than the one shown in FIG. On the other hand, the composite thin line image carrying sheet 20 moved to the left of the folding line 24, and the same screen carrying as in the first embodiment of the present invention described above, for example, the same as shown in FIG. Using the sheet 30 and the windowed sheet 40 similar to that shown in FIG. 4, a variable image display body according to the second embodiment of the present invention as shown in FIG. 10 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 downwardly, the composite thin line carried on the composite thin line image carrying sheet 20 is swung. Since the image 21 slides slightly to the right with respect to the mount 10, the image displayed on the window 41 is the same as that of the variable image display according to the first embodiment of the present invention described above. On the contrary, the original image of the character “A” is repeatedly switched from the image of the character “C” to the image of the character “B” and then to 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 16 (folded piece 15) 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 pushed downward, the portion on the hinge mechanism 50 side is lifted upward simultaneously with the sliding in the right direction. However, while the screen carrying sheet 30 is deformed so as to be convexly curved downward, the screen carrying sheet 30 is maintained in a substantially planar state without being subjected to a stress that causes the whole to bend, while the operation piece portion 52 side thereof is maintained. 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 screened. A difference in the bent state of the carrying sheet 30 and the composite fine line image carrying sheet 20 occurs, a gap 60 is generated between them (Figure 12).

  On the other hand, the variable image display of the present invention is provided with pressing means 16 (folded piece 15) on the surface of the mount 10, and this pressing means 16 (folded piece 15) is the composite thin line image carrying sheet. 20 and the screen carrying sheet 30 are elastically pressed toward the windowed sheet 40, so that a gap 60 is provided between the composite thin line image carrying sheet 20 and the screen carrying sheet 30 in the window 41 that is a variable image display unit. Is not generated, and a good state in which both are in close contact with each other can be maintained, so that a clear image can be displayed (FIG. 11). Further, the surface of the screen carrying sheet 20 is always pressed against and closely adhered to the back surface of the windowed sheet 40 by the pressing means 16, and therefore the level difference between both surfaces is as small as one sheet of paper (windowed sheet 40). Since it is limited to the limit, it is possible to minimize deterioration in appearance due to foreign matter caught in the step (gap) and discomfort due to discontinuity of the pattern.

  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 composite thin line image carrying sheet 20 protrudes from the end of the mount 10 on the folding curve 51 side. It is not suitable for use as a card or a booklet in which an image is changed and displayed by opening and closing the 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 relatively slide the composite thin line image carrying sheet 20 and the screen carrying sheet 30, the screen carrying sheet 30 is used as in the first and second embodiments described above. However, instead of sliding the composite thin line image carrying sheet 20, the position of the composite thin line image carrying sheet 20 may be fixed and the screen carrying sheet 30 may be slid. Is possible. A variable image display according to the third embodiment of the present invention, which is an example of a variable image display having such a structure, includes a mount 10 similar to that shown in FIG. 1 and a score line as shown in FIG. 22, a composite thin line image carrying sheet 20 having no folding lines 23 and 24 and an operation piece 25, and a structure similar to the composite thin line image carrying sheet 20 shown in FIG. The screen carrying sheet 30 on which the line 36, the folding lines 37 and 38, and the operation piece 39 are formed, and the windowed sheet 40 similar to that shown in FIG.

  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. The composite thin-line image carrying sheet 20 is fixed to the mount 10 (or the windowed sheet 40) instead of the screen carrying sheet 30 and the operation piece 12 connected to the mount 10 is used in the same manner as in the case of the body. In the third embodiment of the present invention, the operation piece portion 39 connected to the screen support sheet 30 via the folding line 38 is joined to the screen support sheet 30 instead of the operation piece portion 25 connected to the composite thin line image holding sheet 20. The variable image display body is completed (FIG. 15).

  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 composite thin line image carrying sheet 20 but the screen carrying sheet 30 that slides in the left direction by the swing 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 “C” and further to the character “B”. ”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 16 (folded piece 15) is not provided, the right end portion of the operation piece portion 52 is provided. When the screen carrying sheet 30 is swung so as to be lifted upward, the screen carrier sheet 30 is slid in the left direction and at the same time the portion on the hinge mechanism 50 side is lifted upward. 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 is formed (FIG. 17). On the other hand, the variable image display of the present invention is provided with pressing means 16 (folded piece 15) on the surface of the mount 10, and this pressing means 16 (folded piece 15) is the composite thin line image carrying sheet. 20 and the screen carrying sheet 30 are elastically pressed toward the windowed sheet 40, so that a gap 60 is provided between the composite thin line image carrying sheet 20 and the screen carrying sheet 30 in the window 41 that is a variable image display unit. Is not generated, and a good state in which both are in close contact with each other can be maintained, so that a clear image can be displayed (FIG. 16). Further, the surface of the screen carrying sheet 20 is always pressed against and closely adhered to the back surface of the windowed sheet 40 by the pressing means 16, and therefore the level difference between both surfaces is as small as one sheet of paper (windowed sheet 40). Since it is limited to the limit, it is possible to minimize deterioration in appearance due to foreign matter caught in the step (gap) and discomfort due to discontinuity of the pattern.

  In the variable image display according to the third embodiment of the present invention, the display position of the image appearing by the cooperation of the composite thin line image 21 and the screen 31 is moved or made to appear depending on the swing position of the operation piece 52. Except that it is not possible, the aspect can be variously changed and implemented as in the case of the variable image display of the first embodiment described above. 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. Further, in the case of the variable image display body in such a form that the screen carrying sheet 30 is slid in this way, a plurality of types of composite thin line image carrying sheets 20 are prepared and replaced as necessary. It is possible to display more types of images using two variable image displays, and to increase the types of image change patterns or moving images that can be displayed.

<Fourth Embodiment>
In any 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, and the windowed sheet 40 are each constituted by separate sheets. However, the present invention is not limited to this, and any number of sheets selected from these sheets may be composed of one blank sheet connected to each other.

  FIG. 18 is an expanded view of an example of such a blank sheet. This blank sheet includes a windowed sheet 40, a mount 10, a cover outer sheet 70, a cover inner sheet 80, and a composite thin line image carrying sheet 20. In this order, they are connected to each other via folding lines 45, 71, 81 and 26. As in each of the embodiments of the present invention described above, a folding piece 15 is formed on the mount 10 by the folding line 13 and the cut line 14, and this is also provided at the center of the windowed sheet 40. As in each of the embodiments of the present invention, a window 41 serving as a variable image display is formed. The mount 10 and the cover outer sheet 70 are substantially the same shape and size, but the windowed sheet 40, the cover inner sheet 80, and the composite thin line image carrying sheet 20 are slightly narrower in the left-right direction than the mount 10 and the cover outer sheet 70. It is formed in width. Further, the width of the composite thin line image sheet 20 in the vertical direction is formed to be narrower than other portions, and the composite thin line image 21 is formed on the back surface of the composite thin line image sheet 20. Further, in this example, an extension piece 43 having a narrow width is extended in the vertical direction via a folding line 44 at the center in the vertical direction on the side opposite to the mount 10 of the windowed sheet 40. A cutout 27 that is slightly wider than the extension piece 43 is formed in the vertical direction at the center in the vertical direction at the end on the folding line 26 side of the thin line image carrying sheet 20.

  On the other hand, the screen carrying sheet 30 is formed separately from the blank sheet described above, and the dimensions thereof are smaller than the mount 10 in both length and width, but the pressing means 16 formed on the mount 10 fits in the plane. The vertical and horizontal widths are wider than the vertical width of the composite thin line image carrying sheet 20. The screen 31 is formed so as to include an effective display area at the center of the screen carrying sheet 30, and a blank portion is formed on the four circumferences thereof, and the top and bottom sides of the composite thin line image carrying sheet 20 are formed on the top and bottom sides. The coupling claws 35 to be coupled to the edges of the two are formed into a total of two pairs of left and right pairs by cutting into the screen carrier sheet 30. The distance between the pair of coupling claws 35 in the vertical direction is substantially equal to the vertical width of the composite thin line image carrying sheet 20 (strictly speaking, the composite thin line image carrying sheet 20 is joined to the main body portion of the screen carrying sheet 30. The composite thin-line image carrying sheet is formed in a width with a slight margin necessary for smoothly sliding the composite thin line image carrying sheet in the left-right direction with respect to the screen carrying sheet while being sandwiched between the claws 35.

  First, the folded piece 15 formed on the mount 10 in the blank sheet is folded on the surface of the mount 10 by the folding line 13 to form the pressing member 16, and then the cover inner surface sheet 80, the composite thin line image carrying sheet 20, The cover inner surface sheet 80 overlaps the cover outer surface sheet 70 and the composite thin line image carrying sheet 20 overlaps the mount 10 by the folding curve 81 of the connecting portion between the cover outer surface sheet 70 and the cover inner surface sheet 80, respectively. The cover outer surface sheet 70 and the cover inner sheet 80 are joined to each other on the facing surfaces (FIG. 19). As a result, the cover outer sheet 70 and the cover inner sheet 80 are integrated to form the cover 90, and at the same time, the width of the cover inner sheet 80 in the left-right direction is slightly narrower than that of the cover outer sheet 70. The folding line 26 between the cover inner sheet 80 and the composite thin line image carrying sheet 20 is located slightly to the right of the folding line 71 between the mount 10 and the cover outer sheet 70, and thereby the cover 90 Is formed with a hinge mechanism that slides the composite thin-line image carrying sheet 20 in the left-right direction with respect to the mount 10 when the sheet is swung in the vertical direction with respect to the mount 10 with the folding line 71 as an axis. .

  Next, the screen carrying sheet 30 is placed on the composite thin line image carrying sheet 20 that is folded back on the mount 10, and extends outward in the top and bottom direction beyond both the top and bottom edges of the composite thin line image carrying sheet 20. The back surface of the screen carrying sheet 30 is joined to the surface of the mount 10 at the margin of the screen carrying sheet 30 (FIG. 20). At that time, two pairs of connecting claws 35 formed on the screen carrying sheet 30 are inserted between the composite thin line image carrying sheet 20 and the mount 10, and the composite thin line image carrying sheet 20 is connected to the main body portion of the screen carrying sheet 30. It is made to pinch between the joint claws 35. Accordingly, when the composite thin line image carrying sheet 20 is slid in the left-right direction with respect to the screen carrying sheet 30 bonded to the mount 10 by the action of the hinge mechanism described above, the composite thin line image carrying sheet 20 is moved to the screen carrying sheet. Since it slides accurately in the left-right direction without bending in an oblique direction with respect to 30, the fine line direction of the composite fine line image 21 and the fine line direction of the screen 31 are always kept parallel, thereby always displaying a clear image. It becomes possible.

  Finally, the windowed sheet 40 is folded back so as to be overlapped on the mount 10 by a folding line 45 between the mount 10 and the mount 10 and the windowed sheet 40 are joined at both ends in the vertical direction. The extension piece 43 connected to the composite thin line image carrying sheet 20 is inserted between the composite thin line image carrying sheet 20 and the mount 10 through the notch 27 of the composite thin line image carrying sheet 20 while being bent along the folding line 44. Are joined on the opposite surfaces to complete the variable image display of the fourth embodiment of the present invention (FIG. 21).

  According to the structure of the blank sheet in this development view, all the components except for the screen carrying sheet 30 can be manufactured by a single printing / punching process using a single material, and they are connected in one direction. As the body is made, the manufacturing efficiency and material utilization efficiency are high, as well as the shape and position of each component, folding lines, windows, notches, etc. Therefore, a variable image display that can operate stably and with high accuracy can be easily obtained without requiring any special device for alignment of each component during assembly. Obtainable. Further, when a pattern related to or not related to the variable image is formed on the back surface (the surface after folding) of the windowed sheet 40, the pattern is formed on the back surface (the surface after folding). ) Can be performed in the same process as the formation of the composite thin line image 21, so that the alignment accuracy between the two is high. In particular, when both are related to each other, the design is excellent in that there is no sense of incongruity due to misalignment of both. There is an advantage that a product can be easily obtained.

  The variable image display body of the fourth embodiment of the present invention thus completed can be used as it is as a half-folded card-like product, but a trace hole formed by folding the folded piece 15 on the back surface of the mount 10 is left open. If it is, the appearance may be unsightly, and foreign matter may enter through this hole and cause a failure. The above-mentioned cover paper (not shown) may be covered to conceal the hole. This cover sheet only needs to have a size that at least covers the above-described hole on the back surface of the mount 10, but may be larger than that, for example, a size that covers the entire back surface of the mount 10, The dimensions may cover the entire back surface of the mount 10 and the cover 90.

  The variable image display body according to the fourth embodiment of the present invention can be implemented by variously changing the aspect thereof as in the case of the variable image display body according to each embodiment described above. For example, the cover outer sheet 70 and the cover inner sheet 80 are made narrower in the left-right direction than the mount 10 and are tab-shaped as illustrated as the operation piece 52 in the first to third embodiments of the present invention described above. Moreover, it can also be set as the flat card-like variable image display body as a whole. In the case of such a flat card-like variable image display body, the horizontal width relationship between the cover outer sheet 70 and the cover inner sheet 80 is reversed, similarly to the case of the second embodiment of the present invention. In addition, a variable image display body that can be operated by swinging the cover 90 downward in the drawing surface of the drawing can also be used.
