Description

  The present invention relates to a piece of a jigsaw puzzle and a tray on which the pieces are arranged, and particularly relates to a technique characterized by the shape of the piece and the display on the piece.

As is well known, jigsaw puzzles are a game in which a single completed image is divided into puzzle shapes and cut, and the shapes of the irregularities on the outer edges of each piece and a part of the image drawn on each piece are relied on to combine them. is there. Many jigsaw puzzles are manufactured by printing a finished image on a cardboard surface and cutting it in various patterns.
In general, as shown in FIG. 10, it was divided into two times, (b) the mold was pulled out in the horizontal direction for the first time, (b) the mold was pulled out in the vertical direction for the second time, and (c) the block was formed in the vertical and horizontal directions. Manufactures cut pattern pieces.

  The jigsaw puzzles cut in this way have subtle differences while the shapes of the pieces are similar, and the player has the pleasure of finding a slight difference. Most jigsaw puzzles are created in this way because there are many reasoning elements and it is rare to find the place in the form of pieces even when playing repeatedly.

  Moreover, as shown in FIG. 11, there is also a method of punching a random pattern at a time. The jigsaw puzzle with such a pattern has various shapes of pieces, and has the difficulty and difficulty of predicting the shape of adjacent pieces. The applicant of the present application has also produced jigsaw puzzles of silhouette pieces that take advantage of the fact that these free shapes can be made and make each piece a special shape such as a dog or cat, which increases the fun of assembling.

In the jigsaw puzzles that have been provided in the past, piece designers have devised a line of pieces so that there is no piece of the same shape, for example 1000 pieces. The playability of the jigsaw puzzle is greatly affected by the cut pattern.
In this way, the fun of jigsaw puzzles is that they are arranged by imagining the position on the completed image from the shape of the piece and the image of the surface.

On the other hand, there is a product called puzzle mat for laying on the floor. This is a mat having a thickness of EVA (ethylene vinyl acetate) material. For example, a substantially square piece having a side of about 30 cm is spread and used. Each piece has a large number of projections and depressions provided on the periphery thereof meshed with the projections and depressions of the other pieces to prevent rubbing.
In the puzzle mat, symbols are drawn for each piece and do not combine to create a single completed image, so the pieces are often combined in any direction due to a symmetrical uneven shape. Since the puzzle mat can be combined in any direction for practical use, it is not necessary to consider the orientation in order to reach a completed image like a jigsaw puzzle.

Patent document 1 proposed from the same idea discloses a combination piece that can be connected in both a vertical direction and a horizontal direction in a jigsaw puzzle. According to this disclosure, a convex portion and a concave portion are provided near the corners of each side of the piece body. The convex part and the concave part of both piece main bodies can be fitted to any side of one piece main body in a state where any side of the other piece main body is abutted.
The object of the invention of this document is that the child can freely combine and play a part of the road drawn on the piece while changing the direction, and is an original jigsaw puzzle in which pieces are arranged toward a predetermined completed image is not. Therefore, it is necessary to know the orientation to be arranged by looking at the image on each piece.

  Patent Document 2 proposes a technique for forming piece numbers corresponding to the arrangement and fitting direction of pieces on the back surfaces of a vertical piece and a horizontal piece. This is a technique for assigning numbers in the form of A-1, B-2, etc., in order to reduce the trouble of specifying pieces. If the players are arranged according to the numbers, they can complete the jigsaw puzzle without considering the shape or pattern, but this does not contribute to improving the game playability of the puzzle.

Patent Publication No. 2001-113036 Japanese Patent Publication No. 1997-299610

  As described above, the playability of the jigsaw puzzle is that a position on a predetermined completed image can be imagined from the shape and pattern of each piece. Since the shape has been changed, the combination method of each piece cannot be changed. On the other hand, in the case of a puzzle that can be combined even if the orientation of the pieces is changed as in Patent Document 1, there is no predetermined completed image, and it can be freely assembled and does not have the playability of a jigsaw puzzle.

Furthermore, even if the conventional puzzles that can be freely combined have a side of 30 cm or more as shown in FIG. 12 or a small puzzle of 3 cm or less as shown in FIG. It was one configuration and rotated in only two directions. The number of irregularities that can be set within a certain distance in a jigsaw puzzle punch that is made by folding the steel has a physical limit, and they must be made the same shape that can be precisely combined even if the orientation is changed. Was technically difficult and not particularly necessary.
However, as in the case of the jigsaw puzzle described in this case, only a single color gradation pattern is printed on each piece, and when one image is visible when the whole is assembled, the completed image is viewed. Therefore, it is necessary to look at a certain distance, and in order to hang it on the wall and enjoy it indoors, it is required that the size of one side of the piece is about 1 to 2 cm.

And even if the arrangement of the pieces is changed, all the pieces must be congruent in order for the unevenness to mesh, and for each piece to rotate in four directions, as shown in FIG. It is necessary to attach at least one set of unevenness to the surface. In that case, if the size of the interlock is relatively large as shown in this figure, the image information in the central portion is lost.
As a result, what is required is a form in which an interlock is arranged only in the peripheral portion as shown in FIG. Thus, in this jigsaw puzzle, the size of the piece is 1 to 2 cm, one or more sets of unevenness are arranged on one side, all the pieces are congruent, point-symmetric with respect to the center of the piece, the central part In order to satisfy all the requirements to leave as wide as possible, a considerably high machining accuracy is required.

For example, pinnacle type, which is a corroded blade with melted steel and sharpened blade, can be punched with high accuracy, but this is used for punching seals, etc. Only thickness is lost. The thickness of a jigsaw puzzle is usually around 1.8 mm, and with a thickness of 1 mm, the meshing property is poor and a comfortable playability cannot be ensured.
If the piece is made of plastic, processing by mold molding is possible, but it is more expensive than paper jigsaw puzzles, has less freedom of printing, and is also superior in terms of the paper feel that jigsaw puzzle lovers require It lacks sex.
When making a punching die for punching cardboard as in this case, it can be said that the smaller the piece size is, the more difficult it is to bend precisely because the steel sheet with a total length of 20 m is bent.

  The present invention was created in view of the above-described conventional technology, and although the piece size is 1 to 2 cm, paper that can be meshed with other pieces even if each piece is replaced or rotated. An object of the present invention is to provide a jigsaw puzzle that is made by punching, and to improve the playability of the assembly and the engagement at the time of assembly in such a jigsaw puzzle.

In order to solve the above problems, the present invention proposes the following jigsaw puzzle pieces.
That is, a piece of a jigsaw puzzle that can be meshed with another piece by an interlock part composed of at least one pair of convex and concave portions provided on four sides of a quadrangle, and the shape of each side is point-symmetric with respect to the center of the quadrangle It is possible to mesh with other pieces in the four directions of the upper, lower, left and right sides of the piece. Then, the shape of each side of the piece deviates the convex side adjacent side part adjacent to the convex part toward the inside of the square with respect to the virtual reference line forming the square side, and adjacent to the concave part adjacent to the concave part. The sides are displaced outwardly of the square.
Further, the convex portion and the concave portion are moved on the virtual reference line by a distance corresponding to each deviation so that no step is generated on the side of the adjacent piece when meshing with another piece, and the convex portion is enormous. Since the maximum width of the portion is larger than the minimum width of the constricted portion of the concave portion, separation of the meshed convex portion and the concave portion is prevented.
According to this configuration, since the curvature at the connecting portion between the convex portion and the concave portion and the side can be increased by shifting the adjacent side portion, the interlock portion necessary for meshing can be easily manufactured. In particular, it contributes to the improvement of the meshing property at the time of assembling in a small piece having a side of 2 cm or less.

Also, on the surface of the piece, separately from the completed image information of the puzzle, the piece can be specified and the notation of short distance visibility (long distance invisibility) that can specify the direction of the piece can be given, thereby enhancing the gameability at the time of assembly. It is characterized by increasing.
The above short-range visibility notation is a configuration displayed by two or more kinds of reflectances or differences in gloss or surface roughness, and can be easily implemented by printing with, for example, varnish.

In the present invention, a tray for arranging a plurality of pieces described above can also be provided.
This tray has a matrix display that matches the outer edge to the size of the completed jigsaw puzzle, prepares a frame to prevent the pieces from falling off on four sides, and displays the vertical and horizontal positions of each piece. And

The present invention has the following effects by providing the above configuration.
That is, by making each side point-symmetric, a jigsaw puzzle that can be meshed with other pieces in any direction can be provided. And since the direction is given even if it is a piece that can be meshed in each direction by the short distance visibility notation, it is possible to create work corresponding to the work of aligning the direction from the conventional piece outer shape, as a jigsaw puzzle Gameability can be improved.

At the same time, even if it is a minimal uneven curve that forms a reverse taper, which was difficult with conventional small pieces, it is possible to increase the curvature of the unevenness by applying a deviation to the side adjacent to the unevenness, and to interlock Can do. Thereby, there is no dropout of the piece at the time of assembly, and it can enjoy a game comfortably.
In addition, since the curvature can be increased, the processing accuracy of the concavo-convex portion can be maintained, and a piece that can be accurately meshed can be provided even if the location and orientation are changed.

  And with the notation of short distance visibility, you can identify pieces even if they are difficult to distinguish from the picture of the piece, and even if it is a shape that can be meshed in each direction, the orientation can be determined, so when enjoying a conventional jigsaw puzzle In addition, a work corresponding to the work of assembling the whole from the image printed on the piece surface can be created, and the playability as a jigsaw puzzle can be enhanced.

  In a configuration in which the short-range visibility notation is displayed by two or more types of reflectance or gloss or surface roughness differences, these differences are almost inconspicuous when viewed from a distance, and are used to represent the finished image of the puzzle. Has no effect. On the other hand, when the piece is picked up at the time of assembly, the piece can be identified from the difference in reflection of light, the direction of the piece can be clearly recognized, and a puzzle can be assembled.

  According to the tray of the present invention, the place where each piece should be placed can be confirmed on the tray, so that the piece can be placed directly in the correct position by looking at the piece as in a conventional jigsaw puzzle. . That is, conventionally, puzzles for infants have a display showing the outer shape of the piece on the tray, and some of the puzzles can be assembled by comparing the outer shape, but the piece of the present invention has an outer shape. Because of the congruent shape, such an arrangement could not be made. In this respect, in the tray of the present invention, since the pieces can be arranged with reference to the matrix display, the pieces can be arranged in order from the locations found in the same manner as in the past, which contributes to an improvement in game playability.

It is a figure which shows the pattern of the piece surface of the jigsaw puzzle and short-distance visibility notation which concern on this invention. It is an example of the arrangement | sequence table of the piece by the short-distance visibility notation which concerns on this invention. It is an example of the piece image in a present Example, and an assembly example. It is a figure explaining the subject of this invention.

Hereinafter, embodiments of the present invention will be described based on examples shown in the drawings. The embodiment is not limited to the following.
A jigsaw puzzle piece (1) according to the present invention is shown in FIG. FIG. 1A shows the shape of the surface of the piece, and a pattern with gradation is printed as shown. FIG.1 (b) is explanatory drawing of the short-distance visibility notation printed on the surface. The short-range visibility notation will be described later.

  The first feature of the present invention is the outer shape of the jigsaw puzzle. That is, one convex part (10) and one concave part (11) continuous with the convex part are formed on each side of the quadrangle. The convex part (10) is formed so as to be able to mesh with the concave part (11), and the shape of each side is formed point-symmetrically with respect to the center point (12) of the piece (1). Can be connected vertically and horizontally. The pieces are meshed in any of the four directions.

FIG. 3 is an explanatory diagram showing an example of a surface gradation pattern in this embodiment and a completed image in which such pieces are arranged according to the arrangement table of FIG.
FIG. 3A shows a sheet on which various gradations are printed. Each piece is die-cut on cardboard, for example, about 500 pieces are prepared. Different patterns can be created by using only the necessary pieces. Since it is difficult to make a complete drawing based on the completed drawing, the short distance visibility mark and the arrangement shown in FIG. 2 are arranged based on the arrangement diagram prepared in advance.

  FIG. 3B shows a portrait of Beethoven with 300 pieces. Various patterns can be assembled by using different pieces depending on the pattern, but since the completed image is a kind of mosaic pattern, it is necessary to look at a certain distance to recognize the pattern. The larger the completed image, the more it is necessary to view it from a distance. Therefore, it is desirable to set the piece size to a certain value, for example, 2 cm or less, so that it can be viewed in a general home. Therefore, the outer shape of the piece according to the present invention will be described.

  First, problems with the prior art will be described with reference to FIG. In a piece (100) with a side of about 1 to 2 cm, if the piece is pulled out twice in the vertical and horizontal directions as shown in FIGS. It is difficult to make a point-symmetric square. Also, when pulling out once as shown in (c), it is extremely difficult to bend the punching blade of the steel so that each piece has the same shape. In this case, it is assumed that each piece is separated and pulled out as shown in FIG. 5, but in the following description, the respective pieces are illustrated as being connected.

  Now, as shown in FIG. 4A, when the convex portion (111) and the concave portion (112) are fitted, the height (113) of the convex portion (see the partial enlarged view (110)) is insufficient, and it is removed. There is a problem that the blade cannot be bent sufficiently inward at the curved portion (114). Similarly, the depth of the recess (112) is insufficient, and the punching blade cannot be folded inward.

  Since such a convex part (111) and a recessed part (112) do not have a constricted part (115), even if it fits, it will detach | leave when it pulls diagonally, and it is in the state which does not relate to an interlock. In the assembly process of a jigsaw puzzle, if vibration is applied to a piece that is not interlocked, it will easily disperse and there is a risk that the comfortable game play will be significantly impaired. Therefore, in a general jigsaw puzzle, an enormous portion having a large width is formed on the top side of the convex portion or the bottom side of the concave portion, and a constricted portion having a small width is formed in the middle position, and an interlock portion composed of a combination thereof. Is usually provided.

As described above, in the conventional cut pattern, it is only necessary to design the cut pattern with a curvature that allows bending of the punching blade without making each side symmetrical, so the problem as in the present invention does not occur. For example, as shown in FIG. 10, one side may be one concave portion or convex portion, and a free pattern in which no symmetry is considered as shown in FIG. 11 is possible.
However, in order to interlock with a point-symmetrical piece that can rotate in four directions as in the present invention, one or more sets of unevenness are required on one side, and thus the problem of the present invention arises.
Furthermore, in the case of the piece of the present invention, since the direction and position of the piece are different each time, it is necessary to satisfactorily mesh with any combination of pieces, and the shape of the concave and convex portions must be maintained with high accuracy. The conventional method does not assume meshing with other than the adjacent pieces at the time of die-cutting, and there is a problem that meshing does not work well if the combination is changed.

  One method of solving these problems is to increase the height of the convex portion (111) and the depth of the concave portion (112). However, when creating an image with gradation expression as in the present case, increasing the convex portion and the concave portion leads to reducing the central square portion as shown in FIG. 14A, resulting in the reproducibility of the completed image. Problems arise. From the viewpoint of reproducibility, it is desirable to make all the pieces only squares with no irregularities, but in that case, the comfortable gameability is impaired as described above. The purpose of the present invention is to provide an interlock portion while maintaining the largest square area in the center.

Therefore, a method is proposed in which the height from the side is increased while minimizing the change in the size of the convex portion (111) and the concave portion (112).
First, as shown in FIG. 4B, the side part (131) (see the partial enlarged view (130)) adjacent to the convex part (121) of the piece (120) is a rectangular inward from the position of the dotted line (135). The position is shifted to the upper side in the figure. If it does so, the height (132) of a convex part (121) will become long, and the curvature of a curve part (133) can be enlarged. The recess (122) is formed in the same manner.
According to this method, a portion confined by the convex portion (121) and the concave portion (122) can be formed, and an interlock can be applied.

However, the side part (131) adjacent to the convex part is displaced inward, while the side part (134) adjacent to the concave part (122) is offset to the outside of the quadrangle, so that the two come into contact with each other. There is a step in the part.
As is apparent from the partially enlarged view (140), there are steps between the side portions (141) and (142) adjacent in the left-right direction and between the side portions (143) and (144) adjacent in the vertical direction, As a result, a gap (145) is generated between the four pieces.
Furthermore, when arranged in this way, the pieces are lowered toward the right while clearly producing a step, so when arranged as a whole, a parallelogram shape is formed and the appearance is impaired.

Therefore, in the present invention, as shown in FIG. 6, in the piece (200), a pair of convex portions and concave portions are formed on each side with reference to the square virtual reference line (240), and adjacent to the convex portions. The side portion is displaced inward of the rectangle from the virtual reference line (240), and the concave adjacent side portion adjacent to the concave portion is displaced outward from the virtual reference line (240).
Explaining in the figure, the convex adjacent side portions (203) (213) (223) (233) adjacent to the convex portions (201), (211), (221), (231) are displaced inwardly to form a concave portion ( 202, (212), (222), and (232) are adjacent to the concave adjacent sides (204), (214), (224), and (234).

Further, in order to solve the above problem, the convex portion and the concave portion are moved in parallel on the virtual reference line (240). That is, the convex portion (211) and the concave portion (212) on the left side in the figure will be described as an example. The convex portion adjacent side portion (203) on the upper side and the concave portion adjacent side portion (224) on the lower side are the virtual reference line (240). The convex portion (211) and the concave portion (212) are moved downward (in the direction of the arrow) by a distance displaced downward from the first position. Similarly, all convex parts and concave parts are moved.
As a result of such movement, the lengths of all the adjacent sides of the convex portions and the length of the adjacent side portions of the concave portions become equal, so that no step is generated when the pieces are engaged with each other.

  And the maximum width (201a) of the enormous part of the convex part (201) (same for other convex parts) is larger than the minimum width (202a) of the constricted part of the concave part (202) (same for other concave parts). , Prevents the engagement of the meshed convex part and concave part, and realizes a reliable interlock.

If the outer shape of the present invention is used, there are steps on the sides in the pieces. If they are arranged continuously, the individual pieces are arranged in a slightly inclined state as shown in FIG. 3B or FIG. . However, as shown in FIG. 4B, the steps are not accumulated and are absorbed in a slight inclination of each piece, so that the appearance is the same as that in which the pieces are arranged in the normal horizontal and vertical directions.
As can be seen in FIG. 7, it is the part of the convex part and the concave part where the step is generated, and since the inclination of the piece is slight, it seems that the squares are aligned in appearance, and the appearance is not impaired. Absent.
With the above configuration, the interlock portion can be formed well even in a small piece, and the image information at the center of the piece can be maintained. Contributes to improved engagement and reduced manufacturing costs when assembling jigsaw puzzles.

In addition, when making such a precise cutting die with a size of 2 cm or less, the shape in which the pieces are adjacent to each other as shown in FIG. 10 (c) or FIG. Processing was required. Therefore, in the embodiment of the present invention, it is proposed that the pieces are separated from each other as shown in FIG. When the pieces are arranged adjacent to each other as shown in FIG. 10 (c) or FIG. 11 and extracted with a punching die, each piece is compressed inward from four directions, slightly shrinks, and assembled. This will reduce the meshing ability. When the pieces are arranged separately as in the present case, the design can be made slightly weaker than the original shape, and the engagement can be maintained even if compression occurs.
In particular, when performing gradations as in the embodiment or printing solid colors different for each piece, appropriate printing is performed for each piece by arranging them separately as shown in FIG. Can do.

Next, the display method of the piece surface according to the present invention will be described.
In the present invention, unlike a normal jigsaw puzzle, a specific image that can be recognized even if it is subdivided is not displayed on each piece, and the piece can be arranged in any direction, up, down, left, and right. However, there is a problem that it is difficult to compare and arrange the pieces based on the completed image information like a normal jigsaw puzzle. That is, the surface of each piece is only a slightly different gradation display, and there are many similar pieces, so it is difficult to identify the correct piece, and it is difficult to determine the direction from the image. There is not necessarily high playability. If anything, it would be a monotonous trial-and-error process for completion, which could cause tiredness.
Therefore, the present invention proposes a notation that identifies a piece and makes the player recognize the direction of the piece separately from the image of the piece surface.

  Usually, the notation is performed by assigning a number to the back surface as in Patent Document 2. However, in that case, when trying to assemble the pieces face up, it is troublesome to confirm the direction of the pieces. If you keep the pieces facing down, the problem will be solved, but the original fun of jigsaw puzzles that the patterns will be assembled little by little will be lost, and the pieces will break down when the whole puzzle is turned over after completion Problem arises. Printing the number on the surface solves the problem, but it detracts from aesthetics when viewing the finished image. If printing is made so small that it is not conspicuous, it will be troublesome to distinguish pieces when assembling.

  Therefore, in the present invention, in addition to the image on the surface, the notation of short-range visibility is given by the difference in two or more reflectances or gloss or surface roughness. The gradation notation corresponds to completed image information such as a landscape or a person in a normal jigsaw puzzle, but in the present invention, by adding a short-distance visibility graphic separately from the completed image information, FIG. Since the piece selection and direction are judged while comparing with such an answer diagram, the player can continue to assemble pieces in the same manner as a normal jigsaw puzzle. In the completed state, the figure for piece identification and direction identification cannot be recognized from a certain distance so that the completed image can be enjoyed.

In this embodiment, the mark portion is glossed by printing with UV varnish, and has a diffuse reflectance different from that of gradation image printing. Therefore, the mark can be clearly seen from a short distance.
The player can assemble the puzzle with reference to the short-range visibility notation along with the overall impression of the image. In addition, by printing the same notation on the back surface by a normal printing method, the corresponding piece can be found more easily. Even in that case, the direction of the piece is determined by the near-field visibility notation of the surface.

  As shown by a dotted line in FIG. 1A, a short-distance visibility notation is printed together with a pattern on the piece of this embodiment. FIG. 1B is an explanatory diagram showing only the short-range visibility notation in an easily understandable manner. As a short-distance visibility notation, for example, a cellular phone design is arranged large in the center of the piece. In this cellular phone, the vertical direction of the cellular phone can be clearly discriminated by the antenna (20), the monitor screen (21), and the dial key (22), and the orientation of the piece (1) can be recognized by the orientation of the cellular phone. Yes.

FIG. 8 shows an actual photograph of a piece according to the present invention. FIG. 8A is a photograph of the piece taken from the front, and FIG. 8B is a photograph taken from below. The surface of this piece is printed with a gradation pattern, then a matt varnish is printed on the entire surface, and a cell phone mark is printed using UV varnish.
When the light hits the varnish surface, the closer to the vertical, the lower the reflection intensity, and the print on the paper surface that has passed through the varnish will be visually recognized. Is extremely confusing. In other words, when viewing the completed puzzle, the mark is difficult to see.

  However, when light strikes from an angle, the surface coated with highly smooth UV varnish reflects light based on the law of light reflection, whereas light that strikes the mat varnish or the paper surface is scattered light. Because of this difference, when the piece is viewed obliquely, the mark can be visually recognized as shown in (b), and it can be easily used as a clue at the stage of assembling the piece.

Furthermore, when viewed at a distance after completion, the mark portion is colorless, whereas the original piece surface printing is a single color or color printing, so the mark portion is difficult to see, resulting in the original Only the jigsaw puzzle image will be visible.
In addition, since the jigsaw puzzle is generally coated with a paste of polyvinyl alcohol resin from the surface and bonded to each piece, the jigsaw puzzle becomes more difficult to see due to the glue coating. The short distance visibility notation of the present invention is a notation that is visible only when the piece is viewed from a short distance.

  As shown in FIG. 2, the mark used in the present embodiment is a single color schematic design, and includes symbols, characters, character strings, etc. in addition to animals, plants, tools, food, industrial products, vehicles, etc. ing. These designs must be easy to distinguish the direction and highly distinguishable from other pieces. Furthermore, what is given a certain meaning so that the player can see and enjoy is desirable. For example, if it is a mark, it can be moderately modeled and the design itself can be enjoyed, and if it is a symbol or character, GO! And OH! As described above, it is preferable to improve the playability by using a small word or the like. The player can enjoy the same ideas as a normal jigsaw puzzle, in which pieces are sorted in advance for each similar mark so that the correct piece can be found more easily.

  In the present invention, by assigning a mark to each piece independently as described above, while maintaining the fun of assembling based on a pattern like a normal jigsaw puzzle, different arrangements are made using the mark notation. As a result, it is characterized in that an arbitrary image can be created.

  The sequence table as shown in FIG. 2 can be generated by creating a correct image in advance by computer image processing or manual trial and error and recording the sequence. In addition, the surface image of the piece of the present invention is not limited to the present embodiment, and one completed image may be used as one correct answer as in the past.

In this example, UV varnish was used. However, if the reflectance, gloss, and surface roughness of the short-distance visibility notation part are different from those of other parts, ordinary varnish or any manufacturing method may be used. Also good. For example, the composition may be such that the gloss of the written portion is reduced by mixing and printing fine powder in the paint. Further, the surface roughness may be changed by polishing the surface of the short-distance visibility notation portion or other portions.
Utilizing such characteristics, the present invention proposes a display method for piece recognition and direction recognition that is not found in conventional jigsaw puzzles.

  FIG. 9 is a plan view of the tray (2) for arranging the jigsaw puzzle pieces described above. This tray (2) is comprised by a flat plate, and the guide line (21) which shows the external shape of a puzzle piece is printed on the surface vertically and horizontally. Further, a column display (22) indicating columns A to O corresponding to the guide line (21) and a row display (23) indicating rows 1 to 20 are displayed on the entire side portion, and the player can, for example, correct Pieces can be arranged according to the matrix display displayed in the arrangement table.

  In the piece of the present invention, since there is no feature in the outer shape, it cannot be partially created from a place where it is assembled like a normal jigsaw puzzle. However, by using this tray (2), even if the pieces are taken randomly, it becomes possible to place the pieces directly from the arrangement table at the correct positions, and the game can be enjoyed in the same way as a conventional jigsaw puzzle. .

If the peripheral part (24) which arrange | positions a piece is a paper product like a present Example, it can process to the folding shape for piece fall prevention, and can be fixed so that a piece may not move at the time of an assembly. This may be a resin or wooden tray whose periphery has been processed into a frame shape in advance.
Further, the entire H column (25) and the entire 11th row (26) are filled with the piece shape, and are displayed so that the positions of the rows and columns can be easily identified even in the middle of the part.

  This tray (2) can also be used as a substrate for a piece at the time of decoration by applying glue from above after assembling and bonding the pieces, and cutting off the matrix displays (22) and (23) after drying. A cut line may be put in advance in the matrix displays (22) and (23) so that they can be easily cut off.
