Description

The present invention relates to a retack sheet used for manufacturing a jigsaw puzzle and a manufacturing method thereof, and more particularly to a retack sheet used for manufacturing a jigsaw puzzle in which separated puzzle pieces can be easily fitted and a manufacturing method thereof. ..

Jigsaw puzzles are made by cutting a mount with a pattern on at least one side with irregularities in the vertical and horizontal directions to form multiple puzzle pieces, and then fitting the individual puzzle pieces that are separated into pieces while matching the irregularities on each side. It completes the design of the mount. And this jigsaw puzzle has a function as a plaything that is a puzzle to complete the pattern of the mount, and as an interior decoration item that decorates the room by holding the completed pattern in a holder such as a frame or a panel. It has a function.

As a jigsaw puzzle motif, in order to enjoy a jigsaw puzzle game with a unique motif, for example, in Patent Document 1, a plain flat plate is cut out in a jigsaw puzzle shape, and many of these cut out puzzle pieces are restored to their original shape. It is disclosed that an original jigsaw puzzle is created by freely forming a desired motif in a state of being combined with.

However, in the process of creating the original jigsaw puzzle pattern, when carrying the jigsaw puzzle, it easily scatters from the plate (bottom plate) on which each puzzle piece is placed even with a small impact, and it takes a lot of time and effort to refit it. .. Further, in the original jigsaw puzzle, an image of an original motif is often used without considering the work at the time of fitting. For this reason, if there are many puzzle pieces such as the sky expressed in a small number of colors, only the shape of the puzzle piece can be used as information when fitting, and the fitting work is very difficult. In particular, in jigsaw puzzles with several hundred pieces or more, if each puzzle piece is separated once, it may not be assembled and may be left unattended or thrown away.

Therefore, as disclosed in Patent Document 2, the inventor forms a puzzle piece in a separated state by forming an ultraviolet visualization image showing the position information of the puzzle piece together with a picture image on the surface of the puzzle piece. We proposed a jigsaw puzzle that can be easily fitted and a manufacturing method thereof.

It is a figure for demonstrating the means for suppressing the influence of reflection on the surface of a jigsaw puzzle.

Hereinafter, a suitable embodiment of the jigsaw puzzle, which serves as a reference example for better understanding the present invention, will be described first with reference to the drawings, and then embodiments of the present invention will be described. In the following description, the configurations with the same reference numerals may be omitted because the configurations with the same reference numerals are the same in different drawings.

First, the principle of means for solving a problem in a jigsaw puzzle, which is a reference example for better understanding the present invention, will be described. FIG. 21 is a diagram for explaining the influence of reflection on the surface of the jigsaw puzzle, and FIG. 22 is a diagram for explaining means for suppressing the influence of reflection on the surface of the jigsaw puzzle.

In the jigsaw puzzle shown in FIG. 21, the picture toner image 101 is formed on the surface of the blank paper 100, and the UV toner image 102 containing a fluorescent agent is formed on the surface of the picture toner image 101. In this case, only the portion of the picture toner image 101 is easily affected by minute irregularities and hues on the surface of the blank paper 100 and the gradation of the color, and diffuse reflection is caused by irradiation with light. On the other hand, in the UV toner image 102 formed on the picture toner image 101, the surface of the UV toner is temporarily melted by heating at the time of fixing, so that the UV toner image 102 is not affected by the unevenness of the surface of the blank paper 100. The surface becomes almost mirror-like, and specular reflection is caused by irradiation with light. Therefore, the intensity of the light from the light source that is not absorbed by the pattern toner image 101 or the UV toner image 102 differs between the diffuse reflection portion and the specular reflection portion depending on the visual direction, and the UV toner image 102 is glossy. It is considered that the UV toner image 102 can be visually recognized due to the difference in gloss.

In order to prevent this, the jigsaw puzzle, which is a reference example for better understanding the present invention, prevents the occurrence of diffuse reflection and specular reflection on the surface of the puzzle piece. Specifically, as shown in FIG. 22, a transparent overcoat layer 103 is provided on the surface of the blank paper 100 and the surfaces of the picture toner image 101 and the UV toner image 102. The overcoat layer 103 has a mirror-like surface with a substantially flat surface and is glossy. Light from a light source that is not absorbed by the blank paper 100, the picture toner image 101, and the UV toner image 102 through the overcoat layer 103 causes specular reflection on the surface of the overcoat layer 103, so that depending on the visual direction, The UV toner image 102 will no longer be visible. This is similar to the surface ferro-finishing of photographic images.
When the ultraviolet visualization image is formed with ink having a low viscosity that penetrates the blank paper 100, the surface of the ultraviolet visualization image causes diffuse reflection, so that it cannot be visually recognized and is placed on the pattern toner image 101. The inconvenience that occurs in the formed UV toner image 102 does not occur.

(First form according to the reference example)
Hereinafter, as a first embodiment according to a reference example, a method of creating a jigsaw puzzle as a reference example for better understanding the present invention by using a toner image will be described.
FIG. 1 is a cross-sectional view of an example of a pattern forming paper used in the method for manufacturing a jigsaw puzzle of the present embodiment. The pattern forming paper 1 is provided with a water-soluble layer 3 on the surface of the support 2. The support 2 is made of a material having good water absorption, for example, paper, synthetic paper, a water-soluble film such as polyvinyl alcohol, and the water-soluble layer 3 is made of a material that dissolves by adding water, for example, polyvinyl alcohol, starch, etc. It can be made from a water-soluble substance such as dextrin.

Next, a method of forming an image on the pattern forming paper 1 and attaching the image to the surface of the mount of the plain jigsaw puzzle to be attached will be described. In this embodiment, the image formed on the pattern forming paper 1 is transferred to the retack sheet, and further transferred onto the mount of the jigsaw puzzle.
First, as an image forming step, as shown in FIG. 2, for example, an image data created by a personal computer (not shown) is used to form a toner image 4 on a pattern forming paper 1 using a laser printer or an MFP. In this case, the pattern formed on the pattern forming paper 1 does not need to be inverted, and a non-inverted image which is a normal image is formed.

Here, in this embodiment, the image formed as the toner image 4 is characterized. The toner image 4 has an image 4a in which a required picture image and an ultraviolet visualization image showing position information of a puzzle piece are superimposed, and a transparent overcoat layer 4b further superimposed on the entire surface of the image 4a. .. Ultraviolet visualization images can be seen because they emit light due to weak fluorescence when irradiated with ultraviolet rays or near-ultraviolet rays, but they cannot be seen under normal sunlight or electric lights, and emit light when irradiated with ultraviolet light or black light. An image appears and can be visually recognized. Further, the overcoat layer 4b has a gloss.

In order to form an image 4a in which a required picture image and an ultraviolet visualization image are superimposed and a toner image 4 in which an overcoat layer 4b is provided on the image 4a, for example, a transparent toner image is formed corresponding to a color toner image. Using an image forming apparatus having a transparent toner image forming means for superimposing on a color toner image (see, for example, Japanese Patent Application Laid-Open No. 2002-82508), the transparent toner is not visible in visible light but emits light when exposed to ultraviolet light. By using UV toner, it is possible to superimpose and produce an ultraviolet visualization image. UV toner reacts to ultraviolet light and is also called invisible toner, which is invisible under normal sunlight. As will be described later, the image formed by the UV toner is an image showing the position information of the puzzle pieces, and the position information data given to each puzzle piece based on the arrangement data of each puzzle piece of the jigsaw puzzle used in advance. Is created, imported into an information processing device (personal computer), and printed together with the pattern image data.

Further, in order to provide the overcoat layer 4b, the transparent hot melt material (thickness: 10 to 50 μm) 4b is thermally transferred with a commercially available transparent hot melt transfer paper in the state shown in FIG. 2, or the above-mentioned A transparent toner image forming means can be used. Therefore, as the toner image forming unit, each color (or colorless) of yellow (Y), magenta (M), cyan (C), black (K), transparent UV toner (UV), and transparent toner (T) is used. 6 units may be arranged side by side. If the number of toner image forming units of the image forming apparatus is insufficient, for example, a pattern image is first formed on the pattern forming paper 1, and then the units of the image forming apparatus are replaced to obtain a transparent UV toner (UV). The ultraviolet visualization image by the above and the overcoat layer 4b by the transparent toner (T) may be formed. The transparent toner (T) is also called a clear toner. In the following description of the first and second embodiments, the toner image 4 is the entire surface of the image 4a in which the required pattern image and the ultraviolet visualization image showing the position information of the puzzle piece are superimposed, as described above. It will be described as an image in which a transparent overcoat layer 4b is further formed.

Next, as shown in FIG. 3, as a step of attaching the retack sheet, the retack sheet 7 is placed on the toner image 4 formed on the pattern forming paper 1 and the air is evacuated, while crimping with a spatula or using a thermal roller such as a laminator. Heat crimp and paste. As the retack sheet 7, a transparent resin film 5 provided with a removable pressure-sensitive adhesive 6 on the surface can be used, as will be described later. As the resin film 5, a film using polyvinyl chloride (PVC) having a high thermoplasticity is suitable.

Then, in the state shown in FIG. 3, as a support peeling step, the support 2 of the pattern forming paper 1 is impregnated with water by using a spray or the like. As a result, the water applied to the surface of the water-absorbent support 2 permeates the support 2 and reaches the water-soluble layer 3, while the water-soluble layer 3 is transmitted from the surface of the support 2 to the side surface of the pattern-forming paper 1. It also penetrates from the side.

Since the water-soluble layer 3 is composed of a substance whose material is dissolved by adding water, it is dissolved by the permeated water. Therefore, the support 2 is peeled off from the retack sheet 7, and at that time, the toner image 4 formed on the water-soluble layer 3 is transferred to the re-peelable adhesive 6 of the retack sheet 7.

4A and 4B are views showing a state in which a non-inverted image formed on the pattern forming paper of FIG. 3 is transferred to a retack sheet, FIG. 4A is a sectional view thereof, and FIG. 4B is a diagram. A plan view of 4 (A) seen from the retack sheet side is shown. By the support peeling step, the pattern transfer sheet 10 to which the toner image 4 is transferred can be obtained on the retack sheet 7. After the support peeling step, if necessary, the water and water-soluble substances left on the pattern transfer sheet 10 are removed and dried.

Next, a jigsaw puzzle mount, which is an object to be attached to the toner image 4 of the pattern transfer sheet 10, is prepared. As a jigsaw puzzle mount, a jigsaw puzzle is used in which a plain mount is punched out to form multiple puzzle pieces with the required unevenness on each side, and the irregularities of each puzzle piece are fitted together to form a flat surface. Be done.

As a method for manufacturing this jigsaw puzzle, first, as shown in the cross section in FIG. 5, two sheets of corrugated cardboard 22 having a blank paper 21 adhered to one side and a hot melt type adhesive 23 only on the peripheral portion to be the frame portion 26 are applied. A jigsaw puzzle material 24 is produced by providing the jigsaw puzzle material 24 so that the blank paper 21 side is on the outside. Here, the corrugated cardboard 22 to which the upper blank paper 21 is attached corresponds to the plain mount of this embodiment. As the mount, regardless of the corrugated cardboard 22, a cork material or a wooden board may be used in addition to other papers, and it is not essential to provide the blank paper 21. In addition, in the jigsaw puzzle which is a reference example for better understanding of the present invention, the plain means the one without a pattern on the surface, and the one with a ground pattern such as Japanese paper or cork is also included in the plain. Is done.

After that, as shown in FIG. 5, the jigsaw puzzle material 24 is placed on the upper surface of the cutting table 31 in a predetermined position, and the cutting table 31 is placed on the cutting table 32 for cutting the upper puzzle piece. By moving up and down in the direction of the arrow 33, only the upper blank paper 21 and the corrugated cardboard 22 are die-cut into a predetermined shape and divided into a puzzle piece 25 and a frame portion 26.

6A and 6B are views showing a plain jigsaw puzzle produced in this manner, FIG. 6A shows a plan view, and FIG. 6B shows a partial cross-sectional view.
In the jigsaw puzzle 20, a plain mount is cut out and divided into a plurality of puzzle pieces 25. Each puzzle piece 25 has unevenness of a required shape on each side, and the puzzle piece 25 can be made flat by fitting these unevennesses even after being separated into pieces. Further, the peripheral portion is adhered to the lower corrugated cardboard 22 to form the frame portion 26. The lower corrugated cardboard 22 serves as a bottom plate 28, and together with the frame portion 26, functions as a work plate or holder for assembling the separated puzzle pieces. Further, a cut groove recess 27 created by die cutting is formed between the individual puzzle pieces 25 and between the puzzle piece 25 and the frame portion 26.

Next, a transfer step of transferring the image transferred to the retack sheet 7 onto the mount of the jigsaw puzzle 20 will be described. First, the pattern transfer sheet 10 is aligned and superimposed on the jigsaw puzzle 20 so that the toner image 4 side of the pattern transfer sheet 10 comes to the surface side of the puzzle piece 25 of the jigsaw puzzle 20. FIG. 7 is a diagram showing a state in which the jigsaw puzzle 20 and the pattern transfer sheet 10 are overlapped with each other. In this state, the pattern transfer sheet 10 is on a flat surface, and the toner image 4 is held on the pattern transfer sheet 10 side. Up to.

In this state, the pattern transfer sheet 10 is heated and pressed against the surface of the puzzle piece 25. As a method of heating and pressing, for example, as shown in FIG. 8, a wet cloth 41 is applied onto the pattern transfer sheet 10, and heat and pressure are applied to the pattern transfer sheet 10 from above using an iron 40. The method can be used. Instead of the wet cloth 41, a soft silicone rubber foam sheet or the like may be used.

FIG. 9 is a cross-sectional view showing the relationship between the cut groove recess 27 of the puzzle piece 25 and the pattern transfer sheet 10 when the pattern transfer sheet 10 is heated and pressed against the surface of the puzzle piece 25 in the fixing step. By applying heat and pressure to the pattern transfer sheet 10, the thermoplastic pattern transfer sheet 10 thermally expands, and the stress of the thermal expansion allows the pattern transfer sheet 10 to penetrate deep into the cut groove recess 27 of the puzzle piece 25. As a result, it becomes wrinkled along the pattern of the cut groove recess 27.

On the other hand, since the toner image 4 held on the pattern transfer sheet 10 is heated and pressed against the puzzle piece 25, the toner image 4 is re-fused (re-fixed) to the surface of the puzzle piece 25, and the pattern transfer sheet 10 is used. Transferring is performed by the difference in the fusion force of the toner image 4 from the jigsaw puzzle 20 to the jigsaw puzzle 20. At that time, since the pattern transfer sheet 10 tries to penetrate deep into the cut groove recess 27 of the puzzle piece 25, the toner image 4 of the cut groove recess 27 held in the pattern transfer sheet 10 is also the cut groove of the puzzle piece 25. It is well re-fixed to the entrance portion of the recess 27, that is, the corner portion around the outside of the puzzle piece 25.

As described above, the resin film 5 of the pattern transfer sheet 10 having a high thermoplasticity is a material that expands due to heat and does not melt depending on the re-fixing temperature of the toner image 4. By using a material that does not melt, the cut groove recess 27 Toner images can be transferred up to. As such a material, for example, polyvinyl chloride is suitable. In the state shown in FIG. 9, of the toner image 4 of the pattern transfer sheet 10, the toner image 4 of the portion of the cut groove recess 27 that is not in contact with the puzzle piece 25 is not transferred to the puzzle piece 25 and has a pattern. It will remain on the transfer sheet 10 side.

In the above embodiment, the pattern transfer sheet 10 is heated and pressed by using an iron 40, but the method is not limited to the iron 40. For example, a jigsaw puzzle 20 on which the pattern transfer sheets 10 are overlapped is sandwiched between a pair of holding bodies. , A constant pressure may be applied to heat and press. The sandwiching body may be made of a flexible silicone rubber foam, and a heating element may be provided on at least one of the sandwiching bodies. Further, a pair of rollers may be used as the holding body.

FIG. 10 is a plan view showing the state of the jigsaw puzzle after the fixing process is completed, and is a jigsaw puzzle in a state where the pattern transfer sheet 10 having the transparent retack sheet 7 is attached to the surface of the jigsaw puzzle 20 on which the pattern of the normal image is formed. 20 can be obtained. The jigsaw puzzle 20 obtained as described above can be used as an interior decoration item in a room, and since the retack sheet 7 is attached to the surfaces of the plurality of puzzle pieces 25 and the frame portion 26, each puzzle The pieces 25 do not fall apart and scatter. Further, when the jigsaw puzzle 20 obtained as described above is used as a game puzzle, each puzzle piece 25 can be separated into pieces by peeling off the retack sheet 7. In this embodiment, the retack sheet 7 functions as a transparent resin film for preventing the puzzle pieces from scattering.

FIG. 11 is a diagram showing a state when the retack sheet is peeled off from the jigsaw puzzle of the present embodiment, and FIG. 12 is a cross-sectional view showing a state when the retack sheet is peeled off from the puzzle piece of the present embodiment. A transferred and re-fixed toner image 4 is formed on the surface of the puzzle piece 25 of the jigsaw puzzle 20, and each puzzle piece 25 is in a state where it can be separated by a cut groove. On the other hand, a part of the toner image 4'of the toner image 4 that was not transferred to the surface of the puzzle piece 25 in the transfer process remains on the pattern transfer sheet 10 side. The remaining toner image 4'is a pattern along the minute cut groove portion of each puzzle piece 25 of the jigsaw puzzle 20, that is, the cut groove portion formed by fitting the unevenness of each puzzle piece.

In this way, when the retack sheet 7 is peeled off from the jigsaw puzzle 20, a part of the toner image 4 is stolen by the retack sheet 7, but the stolen toner image 4'is a toner image along the cut groove portion. Since it is 4, the influence is small. Since the toner image 4 is well re-fixed to the corners around the outside of the surface of each puzzle piece 25, even when the unevenness of the puzzle piece 25 is fitted again to reproduce the pattern, a good pattern is obtained. It will be possible to reproduce.

The toner image 4 is an image in which a transparent overcoat layer is further formed on an image in which a required picture image and an ultraviolet visualization image showing position information of a puzzle piece are superimposed. Therefore, under visible light, the ultraviolet visualization image cannot be visually observed with the naked eye, but when the jigsaw puzzle 20 is irradiated with ultraviolet light, the position information of the puzzle piece 25 formed as the ultraviolet visualization image can be seen.

FIG. 13 is a diagram when an ultraviolet light is applied to a jigsaw puzzle which is a reference example for better understanding the present invention. The irradiation range of ultraviolet light is spot S. Then, the position information 53 of each puzzle piece 25 is visualized and appears on the puzzle piece 25 irradiated with ultraviolet light, so that it can be seen. Various types of position information 53 can be used as the position information 53 of each puzzle piece 25, but in this embodiment, the row information 51 of A, B, C, D ... As the coordinate information in the frame portion 26 of the jigsaw puzzle 20. The column information 52 of 01, 02, 03, 04 ... Is formed as an ultraviolet visualization image, and A01, A02, A03, A04 ... Which is a combination of these row information and column information is formed in each puzzle piece 25. It is used as position information 53.

Therefore, even if the retack sheet 7 is peeled off from the jigsaw puzzle 20 and the puzzle pieces 25 are separated from each other, the position by the ultraviolet visualization image formed on the surface of the puzzle piece by irradiating the puzzle piece 25 with ultraviolet light. The puzzle piece 25 can be easily fitted with reference to the information and the coordinate information formed in the frame portion.

It is desirable that the ultraviolet visualization image showing the position information formed on the puzzle piece is formed on the upper surface rather than the pattern image in order to make it easier to see when irradiated with ultraviolet light. Therefore, when forming a toner image using a laser printer or an MFP, the image showing the position information by the UV toner on the surface of the pattern forming paper 1 should be on the upper surface than the pattern image, and the uppermost layer should be transparent. Since it is necessary to form the overcoat layer 4b with toner, it is necessary to determine the arrangement relationship of each toner with respect to the transfer belt in consideration of the order in which the color toner, the UV toner, and the transparent toner are transferred to the pattern forming paper. desirable.
In some cases, the image forming process is performed twice, the pattern image is formed on the upper surface of the pattern forming paper 1, and the image showing the position information by the UV toner and the overcoat layer are formed on the image. You may.

Further, in the above-described form, as the toner image 4, an ultraviolet visualization image showing a required pattern image and position information of a puzzle piece and an image in which an overcoat layer is further superimposed are formed, but the plain jigsaw puzzle (white) shown in FIG. A plain image with an ultraviolet visualization image showing the position information is transferred to the surface of the puzzle) with an ultraviolet visualization image showing the position information of each puzzle piece and a toner image 4 without a pattern image having an overcoat layer on the surface. You may create a jigsaw puzzle. Then, a desired pattern may be drawn on this plain jigsaw puzzle. In this case, even if each puzzle piece is separated at the stage of a plain jigsaw puzzle, the puzzle piece 25 can be easily fitted by irradiating the puzzle piece 25 with ultraviolet light with reference to the position information. Further, even after drawing the pattern, by irradiating the puzzle piece 25 with ultraviolet light, the ultraviolet visualization image comes under the pattern, so that the position information can be seen although the visibility is inferior, so that the conventional jigsaw puzzle can be seen. It will be possible to fit in much easier than.
