JP 2008-206415 A

  This invention makes it a subject to improve hobby property in articles, such as a fishing rod, which has a geometric pattern.

  There is a diamond cut pattern as a geometric pattern. As one of the diamond cut patterns, there is a pattern in which rectangles divided into four triangles are continuously arranged, and it was studied to form this diamond cut pattern on the surface of a fishing rod by inkjet. As a result of extensive research, the present invention has been completed. That is, the fishing rod according to the present invention has a diamond-cut pattern composed of rectangles divided into four triangular regions by two diagonal lines, continuously formed on the surface of the housing by inkjet, and has four triangular regions. At least one of the triangular regions has a gradation.

  The fishing rod has a diamond-cut pattern formed by ink jetting, so that the decorative layer on the surface of the fishing rod can be made thin and easy to manufacture. Since at least one of the four triangular areas has a gradation, the expressive power of the diamond cut pattern is enhanced.

  In particular, it is preferable that each triangular region has a gradation different from each other, and the expression of the diamond cut pattern is further enhanced. In particular, when each region is partitioned by the gradation of each region being different from each other, the boundary between the regions can be visually recognized without drawing a boundary line between the regions.

  In particular, the gradation of each region preferably has a different change rate, and the four regions can be easily partitioned by the difference in the change rate of the gradation.

  Further, the gradation of each region is preferably such that the angle of the gradation line with respect to the rectangular side is different from each other, and the four regions can be easily partitioned by the difference in the gradation line.

  Each region preferably has a gradation in which the brightness changes from an intersection of two diagonal lines of the rectangle toward a predetermined location on each side of the rectangle. In the case of gradation in which the brightness decreases from the intersection of two diagonals of a rectangle toward a predetermined location on each side of the rectangle, it gradually protrudes from the vicinity of each side of the rectangle toward the intersection of the two diagonals of the rectangle. Looks like you are. Conversely, in the case of gradation in which the brightness increases from the intersection of two diagonal lines of a rectangle toward a predetermined location on each side of the rectangle, gradually from the vicinity of each side of the rectangle toward the intersection of the two diagonal lines of the rectangle It seems to be recessed. Therefore, a diamond cut pattern rich in unevenness and three-dimensionality can be obtained.

  The diamond-cut pattern consists of rhombuses divided into four right-angled triangle areas by two diagonal lines, and the diagonal line connecting the vertices of the obtuse corners of the rhombus is along the circumferential direction of the box, The gradation line in each region is preferably in the range of 45 to 90 degrees with respect to a diagonal line connecting the apexes of the acute angle portions of the rhombus. In this structure, it combines with the curved shape along the circumferential direction of the housing, resulting in a diamond cut pattern rich in three-dimensionality.

  In particular, the gradation line of each region of the right triangle is preferably closer to the direction of the diagonal line connecting the vertices of the obtuse corners of the rhombus than the direction orthogonal to the sides of the rhombus, and the curved shape along the circumferential direction of the housing And the diamond-cut pattern enhances the shadow, resulting in a more complex three-dimensional effect.

  In addition, the fishing rod according to the present invention is formed by continuously forming a diamond-cut pattern made of a rectangle divided into four triangular regions by two diagonal lines on the surface of the rod body by ink jet. Of the brightness near the intersection of the diagonal lines and the brightness near each side of the rectangle, one is high and the other is low.

  In the fishing rod having such a configuration, the diamond cut pattern is formed by ink jetting, so that the decoration layer on the surface of the fishing rod can be made thin and easy to manufacture. If the lightness in the vicinity of the intersection of the two diagonals of the rectangle is high and the lightness in the vicinity of each side of the rectangle is low, the vicinity of the intersection of the two diagonal lines of the rectangle appears to protrude beyond the vicinity of each side of the rectangle. It becomes a diamond cut pattern with a three-dimensional feeling. Conversely, if the lightness near the intersection of two diagonal lines of the rectangle is low and the lightness near each side of the rectangle is high, the vicinity of the intersection of the two diagonal lines of the rectangle appears to be recessed from the vicinity of each side of the rectangle. In this case, the diamond cut pattern has a three-dimensional effect.

  In addition, the article having a diamond cut pattern according to the present invention has a diamond cut pattern formed of a rectangle divided into four triangular regions by two diagonal lines, and is continuously formed on the surface by ink jet. Of these areas, at least one triangular area has gradation.

  In addition, the article having a diamond cut pattern according to the present invention has a rectangular cut pattern formed of two rectangles divided into four triangular regions continuously formed on the surface by ink jetting. One of the brightness near the intersection of the diagonal lines and the brightness near each side of the rectangle is high, and the other is low.

  As described above, the diamond cut pattern is formed by inkjet and has gradation, so that the expressive power of the design is improved while the surface pattern is thinly formed, and the hobby of the fishing rod and the article is improved. In addition, a diamond-cut pattern is formed by inkjet, and one of the lightness in the vicinity of the intersection of the two diagonal lines of the rectangle and the lightness in the vicinity of each side of the rectangle is increased and the other is decreased, thereby changing the surface pattern. The expression of the design is improved while forming it thin, and the hobby of fishing rods and articles is improved.

  Hereinafter, a fishing rod according to an embodiment of the present invention will be described with reference to the drawings. The principal part of the fishing rod in this embodiment is shown in FIG. The configuration of the fishing rod is arbitrary, and may be a total rod without a fishing line guide, or a configuration with a fishing line guide and a reel sheet. Moreover, you may be comprised from one housing and may be comprised from two or more housings. The casing 1 is made of fiber reinforced resin, and may be hollow or solid. When the casing 1 is hollow, that is, tubular, the casing 1 can be formed by winding a prepreg sheet in which a reinforcing fiber is impregnated with a synthetic resin such as an epoxy resin around a mandrel and baking it. The surface is subjected to various smoothing processes.

  A decorative layer 2 is formed on the surface of a fishing rod housing 1. The decorative layer 2 may be formed over the entire outer peripheral surface of the casing 1 or may be partially formed. The decoration layer 2 has a diamond-cut pattern portion 3 having a diamond-cut pattern. The diamond cut pattern portion 3 may be formed over the entire circumference of the housing 1 or may be formed in a part of the entire circumference. FIG. 1 shows a part of the entire circumference. It shows what was formed. The outer edge of the diamond cut pattern portion 3 may not be clear, and the diamond cut pattern may gradually become thinner at the peripheral edge of the diamond cut pattern portion 3. The shape of the outer edge of the diamond-cut pattern portion 3 may be various, and in this embodiment, the outer edge shape of the diamond-cut pattern portion 3 is a rectangular shape that is long in the axial direction of the housing 1, but other shapes are used. There may be. Moreover, although the outer edge of the diamond-cut pattern part 3 is a rhombus diagonal line to be described later, the outer edge may be a rhombus side. Moreover, a hollow part may be provided in the diamond cut pattern part 3, and a display part for displaying a logo, various characters, or the like may be provided in the hollow part. A base layer may be provided inside the decorative layer 2, and a transparent protective layer may be provided outside the decorative layer 2. The decoration layer 2 is formed by inkjet. Therefore, the diamond cut pattern portion 3 is formed by ink jetting. As the inkjet ink, UV curable ink is preferable.

  The diamond cut pattern is formed of a rhombus divided into four regions 11, 12, 13, and 14 of a right triangle. Hereinafter, the right-angled triangular regions 11, 12, 13, and 14 are simply referred to as regions 11, 12, 13, and 14, and the four regions 11, 12, 13, and 14 are defined as the first to fourth regions 11, 12, 13, and 14, respectively. 14 may be referred to. The rhombus has four sides 20 and four vertices 21 and 22 and is divided into four right triangles by two diagonal lines 23 and 24. The diamond cut pattern portion 3 is formed by continuously forming diamond cut patterns. That is, the diamond cut pattern is continuously arranged with the four sides 20 of the rhombus as boundaries.

  The aspect ratio of the rhombus is arbitrary, and it may not be a square having an aspect ratio of 1: 1. FIG. 2 shows examples of rhombuses with various aspect ratios. The rhombus has a pair of obtuse corners whose interior angle is an obtuse angle and a pair of acute angle parts whose interior angle is an acute angle. The pair of obtuse angle portions oppose each other, and the pair of acute angle portions oppose each other. The two diagonal lines 23 and 24 are composed of a first diagonal line 23 connecting the vertices 21 of the obtuse angle part and a second diagonal line 24 connecting the vertices 22 of the acute angle part. The intersection 25 of the two diagonal lines 23 and 24 is hereinafter simply referred to as a diagonal intersection 25. When the direction of the first diagonal line 23 is the vertical direction and the direction of the second diagonal line 24 is the horizontal direction, the aspect ratio of the rhombus is vertical: horizontal = length of the first diagonal line 23: length of the second diagonal line 24 It becomes length. The aspect ratio of the rhombus in FIG. 2 (a) is vertical: width = 1: 5, and the aspect ratio of the rhombus in FIG. 2 (b) is vertical: width = 2: 5, as shown in FIG. 2 (c). The aspect ratio of the rhombus is length: width = 4: 5. The aspect ratio is preferably vertical: horizontal = 1: 5 to 4: 5. The diamond-cut pattern in FIG. 1 uses the rhombus in FIG. In the diamond cut pattern portion 3 of the casing 1, the first diagonal line 23 of the rhombus is along the circumferential direction of the casing 1, and the second diagonal line 24 of the rhombus is along the direction of the center line of the casing 1. . In FIG. 1, the axial direction (the direction of the center line) of the housing 1 is indicated by the symbol X, and the circumferential direction of the housing 1 is indicated by the symbol Y. In the following example, description will be made using a rhombus having an aspect ratio of vertical: horizontal = 2: 5 as a representative.

  In FIG. 1 and FIG. 2 and the like, each side 20 and the diagonal lines 23 and 24 of the rhombus are schematically shown by solid lines, but each side 20 and the diagonal lines 23 and 24 of the rhombus are drawn by lines as patterns. Instead, it is only necessary that the borders of the adjacent regions 11, 12, 13, and 14 can be visually recognized as a line by being different from each other in the vicinity of the border. The at least one region 11, 12, 13, 14 of the rhombus preferably has a gradation, and the color is preferably changed in a predetermined direction by the gradation. The direction of gradation change is called a gradation line. The gradation may be a single color gradation or a gradation between two colors having different hues. Moreover, the structure from which lightness changes with gradation may be sufficient. It is preferable that each area | region 11, 12, 13, 14 of a rhombus has a gradation. In that case, the gradations of the regions 11, 12, 13, and 14 can be different from each other in the rate of change, and the gradations of the regions 11, 12, 13, and 14 correspond to the rhombus side 20 The angles of the gradation lines can be different from each other, or they can be combined. In any case, when the rhombus regions 11, 12, 13, and 14 have gradations, it is preferable that the types of gradations are different from each other, and the boundary line is not drawn due to the difference in gradation. However, it is preferable that the right triangles can be distinguished and visually recognized.

  In addition, it is preferable that at least one area | region 11, 12, 13, 14 of a rhombus has a part with a high dot density of an ink, and a part with a low dot density. Moreover, it is preferable that the dot density in each area | region 11, 12, 13, 14 is not uniform. The dot density in the vicinity of the rhombus diagonal intersection 25 is smaller than the dot density in the vicinity of each side 20 of the rhombus, or conversely, the dot density in the vicinity of the rhombus diagonal intersection 25 is higher than the dot density in the vicinity of each rhombus side 20. It is good also as a big structure. It is preferable that the dot density gradually increases from the diagonal intersection 25 toward each side 20 of the rhombus, that is, the hypotenuse of the right triangle due to gradation, or gradually decreases.

  The rhombus may be divided into four regions 11, 12, 13, and 14 without drawing a line on each side 20 or the diagonal lines 23 and 24 of the rhombus, but each region 11, 12, 13, and 14 may have various configurations. The rhombus is preferably divided into four regions 11, 12, 13, and 14 by changing the gradation. As a method of changing the gradation, for example, a method of changing the gradation change rate for each of the regions 11, 12, 13, and 14, or a direction (orientation) of the gradation with respect to the rhombus side 20 for each of the regions 11, 12, 13, and 14. There are ways to change it. Hereinafter, a monochrome gradation will be described as an example. That is, the case where the ink color is black will be described, but the same applies to other single ink colors.

  3 to 5 show a first example of a diamond cut pattern. FIG. 3 shows a diamond cut pattern portion 3 in which diamond cut patterns are continuously arranged, and FIG. 4 shows one diamond forming the diamond cut pattern. As shown in FIG. 4, the brightness in the vicinity of the diagonal intersection 25 of the rhombus is higher than the brightness in the vicinity of each side 20 of the rhombus. The dot density in the vicinity of the rhombus diagonal intersection 25 is smaller than the dot density in the vicinity of each side 20 of the rhombus. Therefore, the color near the diagonal line intersection 25 of the rhombus is lighter than the vicinity of each side 20 of the rhombus.

  The four regions 11, 12, 13, and 14 have low brightness due to gradation from the diagonal intersection 25 toward each side 20 of the rhombus. The four regions 11, 12, 13, and 14 each have a dot density that is increased by gradation from the diagonal intersection 25 toward each side 20 of the rhombus. The rhombus is divided into four regions 11, 12, 13, and 14 because the gradations of the four regions 11, 12, 13, and 14 are different from each other. The change rate of gradation is different for each of the regions 11, 12, 13, and 14. Specifically, each of the regions 11, 12, 13, and 14 has the lowest dot density and the highest brightness at the diagonal intersection point 25. The dot densities at the diagonal intersections 25 of the regions 11, 12, 13, and 14 are equal to each other and the brightness is equal. That is, the highest brightness values of the regions 11, 12, 13, and 14 are equal to each other. However, the maximum brightness values of the regions 11, 12, 13, and 14 may be different from each other. Each region 11, 12, 13, 14 has the lowest brightness at a predetermined location on each side 20 of the rhombus, but the lowest value of brightness is different for each region 11, 12, 13, 14. In the example illustrated in FIG. 4, the minimum value of brightness decreases in order from the first region 11 to the second region 12, the third region 13, and the fourth region 14. Therefore, the lightness gradation change rate is the smallest in the first region 11 and the largest in the fourth region 14.

  FIG. 5 shows the direction (orientation) of gradation in each of the regions 11, 12, 13, and 14 of the diamond cut pattern of FIG. FIG. 5A shows the gradation direction of each of the areas 11, 12, 13, and 14 by contour lines, and FIG. 5B shows the gradation that is the gradation direction of each of the areas 11, 12, 13, and 14. Lines 31, 32, 33, and 34 are indicated by alternate long and short dash lines with arrows. The dot density increases along the gradation lines 31, 32, 33, 34, and the brightness decreases along the gradation lines 31, 32, 33, 34. The direction of gradation with respect to the rhombus side 20 in each region 11, 12, 13, 14 is equal to each other, and the angle of the gradation lines 31, 32, 33, 34 with respect to the rhombus side 20 in each region 11, 12, 13, 14 is mutually different. equal. The gradation lines 31, 32, 33, 34 of the regions 11, 12, 13, 14 all extend from the diagonal intersection 25 toward a predetermined point on each side 20 of the rhombus.

  The angle α of the gradation lines 31, 32, 33, 34 with respect to the second diagonal line 24 is 45 degrees. Accordingly, as shown in FIG. 5A, the gradation contour line is at an angle of 45 degrees with respect to the second diagonal line 24. As shown in FIG. 5B, when a perpendicular line is drawn from the diagonal intersection 25 to the side 20 in the second region 12, the point where the perpendicular intersects the side 20 is a point P, and the gradation line 32 is the side 20. The point Q that intersects with is located between the point P and the apex 22 of the acute angle portion. Therefore, the dot density on the side 20 is not constant over the entire length of the side 20, and the brightness is not constant over the entire length of the side 20. The dot density on the side 20 is the smallest at the apex 21 of the obtuse angle part and the highest at the apex 22 of the acute angle part. The brightness at the side 20 is highest at the apex 21 of the obtuse angle portion and lowest at the apex 22 of the acute angle portion.

  6 to 8 show a second example of the diamond cut pattern. The second example differs from the first example only in the direction of gradation. In the second example, as shown in FIG. 8A, the gradation contour line is parallel to the side 20 of the rhombus, and the gradation lines 31, 32, 33, and 34 are diamond-shaped as shown in FIG. 8B. It is perpendicular to the side 20. Therefore, the point Q where the gradation lines 31, 32, 33, and 34 intersect with the side 20 coincides with the point P. The dot density at the side 20 is constant over the entire length, and the brightness at the side 20 is constant over the entire length. The angle α of the gradation lines 31, 32, 33, and 34 with respect to the second diagonal line 24 is an angle exceeding 45 degrees, specifically 68.2 degrees.

  9 to 11 show a third example of the diamond cut pattern. The third example differs from the first and second examples only in the direction of gradation. In the third example, as shown in FIG. 11 (a), the gradation contour lines are parallel to the first diagonal line 23, and the gradation lines 31, 32, 33, and 34 are shown in FIG. 11 (b). Located on the second diagonal 24. Therefore, the point Q where the gradation lines 31, 32, 33, and 34 intersect with the side 20 coincides with the vertex 22 of the acute angle portion. Further, the angle α of the gradation lines 31, 32, 33, and 34 with respect to the second diagonal line 24 is 0 degree. The gradation line 31 of the first region 11 and the gradation line 33 of the third region 13 are matched with each other, and the gradation line 32 of the second region 12 and the gradation line 34 of the fourth region 14 are matched with each other. The dot density on the side 20 is minimum at the apex 21 of the obtuse angle portion and maximum at the apex 22 of the acute angle portion. Further, the dot density in the regions 11, 12, 13, and 14 is minimum on the first diagonal line 23 including the diagonal line intersection 25. The brightness at the side 20 is highest at the apex 21 of the obtuse angle portion and lowest at the apex 22 of the acute angle portion. The brightness is highest on the first diagonal line 23 including the diagonal line intersection 25.

  12 to 14 show a fourth example of the diamond cut pattern. The fourth example differs from the first to third examples only in the gradation direction. In the fourth example, as shown in FIG. 14A, the gradation contour lines are inclined with respect to the second diagonal line 24 at an angle smaller than the angle of the rhombus side 20 with respect to the second diagonal line 24. As shown in FIG. 14B, the point Q where the gradation lines 31, 32, 33, and 34 intersect with the side 20 is located between the point P and the apex 21 of the obtuse angle portion. The dot density on the side 20 is maximum at the apex 21 of the obtuse angle portion and is minimum at the apex 22 of the acute angle portion. The brightness at the side 20 is lowest at the apex 21 of the obtuse angle part and highest at the apex 22 of the acute angle part. The angle α of the gradation lines 31, 32, 33, 34 with respect to the second diagonal line 24 is an angle α exceeding 45 degrees, specifically 85.5 degrees, which is 68.2 degrees in the second example. Is even larger, approaching 90 degrees.

  15 to 17 show a fifth example of the diamond cut pattern. The fifth example differs from the first to fourth examples only in the direction of gradation. In the fifth example, the contour lines of the gradation are parallel to the second diagonal line 24 as shown in FIG. 17A, and the gradation lines 31, 32, 33, and 34 are the first as shown in FIG. Located on the diagonal line 23. Therefore, the point Q where the gradation lines 31, 32, 33, and 34 intersect with the side 20 coincides with the vertex 21 of the obtuse angle portion. The gradation line 31 of the first region 11 and the gradation line 32 of the second region 12 are coincident with each other, and the gradation line 33 of the third region 13 and the gradation line 34 of the fourth region 14 are coincident with each other. The dot density on the side 20 is minimum at the apex 22 of the acute angle part and is maximum at the apex 21 of the obtuse angle part. Further, the dot density in the regions 11, 12, 13, and 14 is minimum on the second diagonal line 24 including the diagonal line intersection 25. The brightness at the side 20 is highest at the apex 22 of the acute angle part and lowest at the apex 21 of the obtuse angle part. The brightness is highest on the second diagonal 24 including the diagonal intersection 25. The angle α of the gradation lines 31, 32, 33, 34 with respect to the second diagonal line 24 is 90 degrees.

  As described above, since the diamond cut pattern portion 3 is formed on the surface of the fishing rod housing 1 in the present embodiment by ink jetting, the decorative layer 2 can be made thin. And since the decoration layer 2 including the part of the decoration layers 2 other than the diamond-cut pattern part 3 can be formed by one printing process with an inkjet, the manufacturing process of the decoration layer 2 becomes easy.

  Moreover, since the brightness in the vicinity of the diagonal intersection 25 is higher than the brightness in the vicinity of each side 20 of the rhombus, the vicinity of the diagonal intersection 25 seems to protrude outward in the radial direction of the housing 1 with respect to the vicinity of each side 20 of the rhombus. . Therefore, a three-dimensional decoration can be obtained. In particular, the brightness of each of the regions 11, 12, 13, and 14 is lowered by gradation from the diagonal intersection 25 toward each side 20, so that the slope is natural with the diagonal intersection 25 as the top and each side 20 as the bottom. The three-dimensional effect is further enhanced.

  In addition, since the gradation change rate is different for each of the regions 11, 12, 13, and 14, the boundary between the regions 11, 12, 13, and 14 becomes clear, and the adjacent rhombus regions 11, 12, and 13 , 14 also becomes clear. Therefore, the three-dimensional feeling of the diamond cut pattern is further increased.

  Among the first to fifth examples described above, the protruding feeling in the vicinity of the diagonal intersection 25 is particularly remarkable in the first and second examples, and the diagonal intersection 25 is the top and each side 20 is the bottom. It looks like a square pyramid. On the other hand, the third example has a feature that the diamond cut pattern looks sharp, and the boundary is emphasized to make it stand out. In the fourth example and the fifth example, each rhombus appears to be curved and raised along the first diagonal line 23 like a fish scale, and the pattern is rich in unevenness.

  The angle α of the gradation lines 31, 32, 33, and 34 of the regions 11, 12, 13, and 14 with respect to the second diagonal 24 is 45 degrees in the first example, 68.2 degrees in the second example, and third. Is 0 degrees, the fourth example is 85.5 degrees, and the fifth example is 90 degrees. When the angle α with respect to the second diagonal 24 of the gradation lines 31, 32, 33, 34 of each of the regions 11, 12, 13, 14 is in the range of 45 to 90 degrees, it becomes a diamond cut pattern particularly rich in stereoscopic effect, Moreover, when the first diagonal line 23 is along the circumferential direction of the housing 1 as in the present embodiment, the three-dimensional effect of the diamond cut pattern is further increased in combination with the curved shape of the housing 1. In particular, as in the fourth example, the gradation lines 31, 32, 33, 34 of the regions 11, 12, 13, 14 are further in the direction of the first diagonal line 23 than the direction orthogonal to the rhombus side 20. When close, since the first diagonal line 23 is along the circumferential direction of the housing 1, a complicated three-dimensional effect is obtained by the synergistic effect of the unevenness of the diamond-cut pattern and the curved shape of the outer peripheral surface of the housing 1. . In the aspect ratio of the rhombus, the angle α with respect to the second diagonal 24 of the gradation lines 31, 32, 33, and 34 of the regions 11, 12, 13, and 14 is greater than 68.2 degrees and 90 degrees or less. It is preferable.

  In the first to fifth examples, the directions of the gradations of the regions 11, 12, 13, and 14 with respect to the sides 20 are equal to each other.

  As described above, there are many combinations even in the configuration in which the directions of the gradation lines 31, 32, 33, and 34 of the regions 11, 12, 13, and 14 with respect to the sides 20 are different from each other. Even in the case where the direction of the gradation line 31, 32, 33, 34 with respect to the side 20 is different for each of the regions 11, 12, 13, 14 as in the sixth to ninth examples, the vicinity of the diagonal intersection 25 The prominent sense of protrusion is visible, and the pattern is rich in three-dimensionality.

  In the above embodiment, the fishing rod rod 1 has been described as an example. However, the present invention can be applied to the case where the decorative layer 2 having the diamond-cut pattern portion 3 is formed on the outer peripheral surface of the spinning reel spool, for example. Thus, the target article may be various, and is particularly suitable for an article having an outer peripheral surface, and a diamond-cut pattern is formed so that the first diagonal line 23 of the rhombus is along the circumferential direction of the outer peripheral surface. Then, due to the synergistic effect of the curved shape along the circumferential direction of the outer peripheral surface and the gradation of the diamond cut pattern, the shadow is enhanced, and the three-dimensional effect of the diamond cut pattern is enhanced. However, the diamond-shaped second diagonal line 24 may be along the circumferential direction of the outer circumferential surface, and the first diagonal line 23 and the second diagonal line 24 may be along the direction inclined with respect to the circumferential direction of the outer circumferential surface. May be. In addition, the target article may be various, and the portion to which the diamond cut pattern is applied may be a convex or concave curved surface that is not the outer peripheral surface, or may be a flat surface.

  In addition, the diamond cut pattern has been described as having a rhombus divided into four right-angled triangular regions 11, 12, 13, and 14 by two diagonal lines 23 and 24. However, the diamond cut pattern has various rectangles. For example, it may be various rectangles such as a parallelogram whose diagonals are not orthogonal to each other and a saddle shape whose opposite sides are not parallel. Contrary to the above example, the vicinity of the diagonal intersection 25 may be shown to be depressed by a gradation in which the brightness near the diagonal intersection 25 is low and the brightness near each side 20 is high. Various color patterns may be used instead of monochrome, and even in that case, it is preferable to change the brightness as described above. Further, not the lightness but the hue or the like may be changed from the diagonal intersection 25 toward each side 20 by gradation. The gradation line may not pass through the diagonal intersection 25.
