  The game board is provided with image display means at substantially the center of the game area. In recent years, this image display means has a tendency to become very large, and accordingly, the opening for the image display means provided in the approximate center of the game board also becomes very large, and the rigidity of the game board itself tends to decrease. is there.

  Therefore, in the case of a game board used for such a game board, after press-fitting each molding punch into the game board in the punch hole forming process, when raising and lowering the lifting platform, each molding punch is withdrawn from the game board, The center part of the game board is elastically deformed so that the center part of the game board curves upward due to the pulling resistance when each molded punch is pulled out from the game board, and a part of the decorative sheet peels off in the vicinity of the related punch hole such as a mounting punch hole. There is a problem such as rising up.

  That is, the mounting punch hole and the positioning punch hole are larger in diameter and depth than the game nail punch hole and have a larger pull-out resistance. Therefore, when the molded punch is removed from the game board, Pulling force is applied. For this reason, when a mounting punch hole or the like is formed around the opening for the image display means on the center side of the game board, the game board is greatly elastically deformed upward by the pulling force, and the punch is formed with respect to the game board. Will be inclined obliquely, and there will be problems such as the decorative sheet tearing or rising up in the vicinity of the periphery of the mounting punch hole or the like due to distortion of the game board accompanying the inclination.

  And if the decorative sheet is damaged in this way, the appearance of the parts that are not hidden by the game parts such as the image display means is lowered, and in the subsequent game nail nailing process by the nailing machine, Since the game nail held by the hitting head moves vertically and horizontally in the vicinity of the surface of the decorative sheet, there is a concern that the damaged portion of the decorative sheet is caught by the tip of the game nail.

The present invention, such view of the conventional problems, when forming the associated punch holes associated with the mounting of the game components to the game board, can minimize the elastic deformation of the gaming board by pulling force of the forming punch, An object of the present invention is to provide a ball game machine capable of preventing the decorative sheet from being damaged near the periphery of the associated punch hole.

The present invention includes a game board in which an opening part is disposed in and game territory region decorative sheet is attached to the front surface, and a game unit article is inserted into the opening is attached to the front surface of the game board, the game comprising a game board which in realm and a plurality of gaming nails provided on the front surface of the game board, associated punch holes pinball game machine provided relating to the mounting of the gaming unit products in front of the game board in, the game area by remote outside the front of the game board, with the associated punch hole the decorative sheet damage preventing punch holes to prevent damage in the surrounding vicinity of, for preventing the damage The punch hole is formed by a molding punch that operates integrally with the molding punch for the related punch hole and suppresses elastic deformation of the game board due to pulling resistance of the molding punch when the punch hole is pulled out .

According to the present invention, when forming the associated punch holes associated with the mounting of the gaming unit goods to the game board, you can minimize the elastic deformation of the gaming board by pulling force of the formed shape Pont Ji, near the relevant punches holes it is possible to prevent damage to the decorative sheet in the vicinity.

  An opening 31 for the special symbol starting means 19 and an opening 32 for the special winning means 20 are provided below the opening 30 for the image display means 18. The opening 34 for the normal symbol starting means 22 is provided on the left side of the opening 30 for the image display means 18 and above the opening 33 for the normal winning means 21.

  As shown in FIGS. 3 and 4, the game board 14 is provided with an associated punch hole 36 related to the attachment of the game component in the vicinity of the periphery of each opening 30 to 33, and the game nail corresponding to each game nail 24. Punch holes 37 are provided, and a plurality of damage prevention punch holes 38 are formed outside the game area 9 at a predetermined interval.

  In this embodiment, a large number of punch holes 36 and 37 are intensively arranged on the left side from the upper left part to the lower center part of the game board 14. Therefore, damage prevention punch holes 38 are provided in a substantially straight line in the vicinity of the left and right side edges of the game board 14, and each damage prevention punch hole 38 corresponds to the distribution of the left and right punch holes 36 and 37. The number of the punch holes 38 for preventing damage on the left side where the plurality of punch holes 36 and 37 are concentrated unevenly is larger than the number on the right side. The damage prevention punch hole 38 is covered with the outer periphery decoration member 29 when the outer periphery decoration member 29 is attached.

  In the related punch hole 36, when each game component such as the image display means 18 is attached to the game board 14 as illustrated in FIG. There are a positioning punch hole 41 for positioning by inserting the protruding positioning protrusion 40 and a mounting punch hole 43 for facilitating screwing of the mounting screw 42 to the outer peripheral flange 39.

  For example, in the case of the large-sized image display means 18, as can be seen from FIG. 3, the outer peripheral collar portion 39 is positioned on the game board 14 at a plurality of locations in the circumferential direction, and the outer peripheral collar portion at a plurality of locations larger than the positioning locations. It is necessary to fix 39 to the game board 14. Therefore, in the vicinity of the outer periphery of the opening 30 for the image display means 18, there are mounting punch holes 43 at a plurality of positions at predetermined intervals in the circumferential direction, and close to the mounting punch holes 43 at some of the plurality of positions. Thus, a positioning punch hole 41 is arranged. A part of these punch holes 41 and 43 is provided in a projecting portion 44 projecting inside the opening 30.

  The game nail punch hole 37 is for making it easy to pierce the tip of the game nail 24 when nailing. The damage prevention punch holes 38 are formed in the vicinity of the periphery of the punch holes 41 and 43 when forming a large number of positioning punch holes 41 and mounting punch holes 43 in the game area 9 in the punch hole forming process. Are provided on the left and right side portions of the game board 14 outside the game area 9 at predetermined intervals in the longitudinal direction.

  As shown in FIG. 6, the positioning punch hole 41 and the mounting punch hole 43 have a substantially cylindrical inner peripheral surface 46 that is substantially perpendicular to the front surface of the game board 14 and has a substantially conical shape. The diameter and depth are larger than that of the game nail punch hole 37. Similarly, the damage preventing punch hole 38 also has a substantially cylindrical inner peripheral surface 47 that is substantially perpendicular to the front surface of the game board 14, and its diameter is larger than that of the positioning punch hole 41 and the mounting punch hole 43. It is. The depth of the damage preventing punch hole 38 is approximately the same as that of the positioning punch hole 41 and the mounting punch hole 43.

  In the punch hole forming step, when each of the formed punches 59 to 62 (see FIG. 8) is pulled out from the game board 14, the pulling resistance at each damage preventing punch hole 38 is determined by the positioning punch holes 41 and the mounting punch holes. 43, and the sum of the pull-out resistances of the damage prevention punch holes 38 is larger than the sum of the pull-out resistances of the positioning punch holes 41 and the mounting punch holes 43.

  Accordingly, each damage preventing punch hole 38 has a force for pulling the forming punches 61 and 62 from the positioning punch hole 41 and the mounting punch hole 43 when the forming punch 60 is removed from the damage preventing punch hole 38. It can be stored in the game board 14 and is necessary for the molding punches 61 and 62 to be removed from the positioning punch hole 41 and the mounting punch hole 43 substantially simultaneously when the molding punch 60 is removed from the damage prevention punch holes 38. Power is accumulated in the game board 14.

  The gauge press apparatus used in the punch hole forming step is configured as shown in FIG. This gauge press device is arranged in the middle of the transport means 50 for transporting the game board 14, a cradle 51 that receives the game board 14 from below, and a cradle that is provided on the upper side of the cradle 51 so as to be movable up and down. 52 and a gauge tool 53 attached to the lower side of the lifting platform 52. The lifting platform 52 is movable up and down with respect to the support frame 54 via a lifting guide mechanism 56 and is driven by a lifting cylinder 57. As shown in FIG. 8, the gauge tool 53 has a large number of formed punches 59 to 62 corresponding to the punch holes 37, 38, 41, and 43 on the game board 14 side, and a support that supports the formed punches 59 to 62. Plate 63.

  The forming punches 59 to 62 include a forming punch 59 for forming the game nail punch hole 37, a forming punch 61 for forming the positioning punch hole 41, a forming punch 62 for forming the mounting punch hole 43, and a damage preventing punch. There is a forming punch 60 for forming the hole 38, and the forming punches 59 to 62 are arranged corresponding to the punch holes 37, 38, 41, 43 shown in FIG.

  Each of the formed punches 59 to 62 has a mounting portion 65 inserted into the support plate 63, a large diameter portion 66 that contacts the lower side of the support plate 63, and protrudes downward from the large diameter portion 66 and includes punch holes 37, The punching holes 37, 38, 41, 43 are formed by press-fitting the forming part 67 into the game board 14.

  A molding punch 59 for the game nail 24 has a molding portion 67 formed in a conical shape. The molding portions 67 of the other molding punches 60 to 62 include a right cylindrical portion 69 corresponding to the substantially cylindrical inner peripheral surfaces 46 and 47 of the punch holes 38, 41 and 43, and a tip of the right cylindrical portion 69. And a conical sharpened portion 70.

  The axial dimensions of the large-diameter portion 66 of the molding punches 59, 61, 62 are substantially the same. The dimension in the axial direction of the large-diameter portion 66 of the molding punch 60 is larger than that of the other molding punches 59, 61, 62, and the lower surface thereof serves as a stopper when the molding punches 59 to 62 are press-fitted. The protruding amount of the forming punch 60 from the support plate 63 to the tip of the forming portion 67 is substantially the same for the forming punches 61 and 62. A holding member 71 is provided on the fixed side of the transport means 50 to press the left and right ends of the game board 14 when the molding punches 59 to 62 are pulled out from the game board 13.

  When the punch holes 37, 38, 41, 43 are formed in the game board 14, the game board 14 to which the decorative sheet 13 is attached and the openings 30 to 34 are provided is transferred to the gauge press device by the transport means 50. Supply. And after the game board 14 stops on the receiving stand 51, the raising / lowering stand 52 is lowered | hung with the raising / lowering cylinder 57, and the lower surface of the large diameter part 66 of the shaping | molding punch 60 contacts the game board 14 as shown in FIG. The molding punches 59 to 62 are press-fitted into the game board 14 to the position. The press-fitting amounts of the molding punches 60 to 62 at this time are substantially the same.

  Next, the lifting platform 52 is moved up by the lifting cylinder 57 and the molded punches 59 to 62 are pulled out from the game board 14, whereby predetermined punch holes 37, 38, 41, 43 are formed at predetermined positions on the game board 14. Can be molded. The game board 14 after forming the punch holes 37, 38, 41, 43 is transported to the next process by the transport means 50.

  When the lifting platform 52 is raised after the press-fitting of the forming punches 59 to 62, each of the forming punches 60 to 62 is press-fitted into the game board 14 with a predetermined pulling resistance, so that the game board is passed through the forming punches 60 to 62. 14 is lifted and its left and right ends abut against the lower side of the presser member 71, and the left and right ends of the game board 14 are pressed downward by the presser member 71.

  Even after the left and right ends of the game board 14 are pressed by the pressing member 71, the molding punches 60 to 62 are integrally lifted as the lifting platform 52 is raised, so that the pulling resistance of the molding punches 60 to 62 is reduced. A corresponding upward force is applied to the game board 14 via the respective molding punches 60 to 62, and when the pulling force exceeds the pulling resistance, the respective molding punches 60 to 62 are pulled out from the game board 14. The pulling resistance of the forming punch 59 is practically negligible.

  Accordingly, when the molding punches 60 to 62 are removed from the game board 14 in a microscopic manner, if there is no damage prevention molding punch 60, the positioning punches 61 and 62 are positioned. Since the pull-out resistance is relatively small, the pulling force exceeding the pull-out resistance is applied to each of the positioning and mounting molding punches 61 and 62, so that the lift 52 is raised from the side closer to the presser member 71 to the center side sequentially. The molding punches 61 and 62 are removed from the game board 14 with a time difference synchronized with the speed.

  At this time, until the last molding punches 61 and 62 come out, the game board 14 is elastically deformed so that the center side becomes higher due to the pulling resistance of the molding punches 61 and 62, and in particular, the opening is formed at the center side of the game board 14. The protrusions 44 and the like that protrude into the 30 and are structurally weak are greatly elastically deformed upward. As a result, for example, in the protruding portion 44, the game board 14 is inclined with respect to the molded punches 61 and 62 as shown in FIG. A damaged portion 72 such as a raised surface was formed.

  However, by providing a plurality of damage prevention forming punches 60 on the outer peripheral portion of the game board 14 so that the sum of the pulling resistances is larger than the sum of the forming punches 61 and 62 in the game area 9, the decorative sheet is provided. It is possible to prevent damage such as 13 swells.

  This is because, as shown in FIG. 8, a molding punch 60 having a large pull-out resistance is press-fitted into the game board 14 in the vicinity of the left and right presser members 71. The punches 60 to 62 are raised together. For this reason, even if the game board 14 abuts against the holding member 71, the forming punches 61 and 62 in the game area 9 will not come off unless the forming punch 60 in the vicinity of the holding member 71 comes off.

  Moreover, each molding punch 60 in the vicinity of the pressing member 71 does not come out of the game board 14 unless a pulling force equal to or greater than the sum of its pulling resistances is applied. A force larger than the sum of the pull-out resistances 61 and 62 is rapidly accumulated in the game board 14.

  Then, when the force exceeding the sum of the pulling resistances of the respective molding punches 60 is accumulated and the pulling force applied to the respective molding punches 59 exceeds the pulling resistance, the respective molding punches 60 are pulled out from the game board 14 almost simultaneously.

On the other hand, when the molding punch 60 starts to come off from the game board 14, the molding punch 60 and the game board 14 are brought into a sliding contact state, and the pull-out resistance is rapidly reduced. A large force equal to or greater than the sum of the pull-out resistances 61 and 62 is instantaneously applied to the molding punches 61 and 62 at substantially the same time or at very short time intervals. Therefore, each of the molded punches 61 and 62 cannot resist the pulling force due to the large force, and as shown in FIG. 10, after the molded punch 60 starts to be pulled out, it starts to slide with respect to the game board 14 almost at the same time. It is pulled out from the game board 14 at a stretch without any allowance.

  Therefore, even the molding punches 61 and 62 in a relatively weak portion such as the protruding portion 44 can be removed from the game board 14 while maintaining a substantially vertical state with respect to the game board 14, and the punch holes 41 and 43 are formed. The conventional decorative sheet 13 can be prevented from being damaged, and the nailing operation can be easily performed in the subsequent nailing process.

  Further, the damage preventing punch hole 38 is covered with the outer peripheral decorative member 29 attached to the outside of the game area 9 and is not exposed to the front surface. Accordingly, since the damage preventing punch hole 38 is not visible from the transparent window 10 of the glass door 4, the appearance of the game board 11 is also determined when determining the size of the damage preventing punch hole 38 and the molded punch 60. It can be easily determined in consideration of necessary pull-out resistance regardless of the above. Moreover, even if a part of the decorative sheet 13 is damaged around the damage preventing punch hole 38 when the forming punch 60 is press-fitted, there is no particular problem.

  When the molded punches 61 and 62 are pulled out of the game board 14, the game board 14 due to the pull-out resistance of the molded punches 61 and 62 is also obtained by, for example, pressing the center portion of the game board 14 downward by causing the pressing member to protrude from the lifting platform 52. However, in this case, the structure of the gauge press apparatus is complicated, for example, by providing a pressing member avoiding the molding punches 61 and 62 on the lower side of the lifting platform 52. In addition, there is a problem that the decorative sheet 13 on the front surface of the game board 14 is damaged by the pressing member. However, according to this embodiment, it is only necessary to provide the molding punch 60 on the lower side of the lifting platform 52 in the same manner as the other molding punches 61 and 62. Therefore, the structure of the gauge press device can be facilitated, and the game There is no problem of damaging the decorative sheet 13 in the region 9.

  FIG. 11 illustrates a second embodiment of the present invention. In this embodiment, the damage preventing punch hole 38 is provided only on the left side where a large number of punch holes 36, 37 are concentrated and uneven, and the damage preventing punch hole 38 is provided on the right side where there are few punch holes 36. Not.

  A plurality of damage prevention punch holes 38 are provided along the longitudinal direction on the left side of the game board 14, but a plurality of damage prevention punch holes 38 are concentrated on the upper side A at predetermined intervals. Has been.

  On the other hand, on the lower side B, there is an opening 33 that is long in the vertical direction between the inner punch holes 36 and 37, so that the damage preventing punch holes correspond to the upper and lower ends of the opening 33 or the vicinity thereof. A damage preventing punch hole 38 is provided corresponding to a portion other than the substantially central portion in the vertical direction of the long opening 33, such as 38 is disposed.

  When there is a large opening 33 between the inner punch holes 36 and 37 as described above, the damage preventing punch hole 38 may be disposed so as to avoid the central portion in the vertical direction of the opening 33. This is because even if the damage preventing punch hole 38 corresponding to the central portion of the opening 33 is disposed, the force accumulated in the game board 14 when the damage preventing punch hole 38 is formed is absorbed by the opening 33. This is because the inner punch holes 36 and 37 are not sufficiently added.

  In addition, there is an associated punch hole 36 on the upper right side and the upper and lower center part on the right side of the game area 9, but the associated punch hole 36 is close to the right edge pressed by the pressing member 71, so that the surrounding decorative sheet 13 may be damaged. There are few. Therefore, the damage preventing punch hole 38 on the right side of the game board 14 may be omitted.

  FIG. 12 illustrates a third embodiment of the present invention. In this embodiment, the upper side A and the lower side B of the game board 14 are arranged with different intervals between the damage preventing punch holes 38. The associated punch holes 36 on the upper side A of the game board 14 are arranged in a narrow area C on the left side of the game area 6 that is relatively close to the left edge of the game board 14, and the number thereof is also relatively small. On the other hand, the related punch holes 36 on the lower side B are arranged in a region D far from the left edge of the game board 14 and beyond the center in the left-right direction of the game region 6, and the number thereof is very large compared to the upper side A. It is increasing.

  Therefore, the upper side A where the related punch holes 36 are arranged in the near region C and the number thereof is small increases the interval between the damage preventing punch holes 38, and the punch holes 36 and 37 are arranged in the far region D and the number of the lower portions is large. On the side B, the interval between the punch holes 38 for preventing damage is reduced to increase the number.

  Further, the sum of the pull-out resistance of each damage prevention punch hole 38 is determined to be closer to the damage prevention punch hole 38 than the lower rigidity portion (low rigidity portion) 14d of the upper side portion 14a and the lower side portion 14b of the game board 14. The sum of the pull-out resistances of the related punch holes 37 is set to be greater than or equal to the sum.

  Also in this case, when the forming punch 60 is pulled out from the game board 14, force is accumulated in the game board 14 due to the pull-out resistance, but damage prevention punch holes 38 are formed on the upper side A and the lower side B of each game board 14. The accumulated force is different depending on the difference in the interval, and a larger force is accumulated on the lower side B than on the upper side A. And when each shaping | molding punch 60 begins to detach simultaneously, the force accumulate | stored in the upper side A and the lower side B will be added to the shaping punches 61 and 62 of each area | region C, D.

  For this reason, on the lower side B of the game area 9, the plurality of molding punches 61 and 62 are located far from the damage preventing punch hole 38, and the lower part B is concentrated in a narrow area. The force accumulated in the game board 14 can be reliably applied to the molding punches 61 and 62 on the side B without being attenuated.

  Further, when the force accumulated when the forming punch 60 is pulled out is applied to the forming punches 61 and 62, the force is absorbed by the portion 14d having a small rigidity of the upper side portion 14a and the lower side portion 14c of the game board 14. Therefore, even when there are related punch holes 36 on both sides of the portion 14d with low rigidity, the sum of the pull-out resistance of the punch holes 38 for damage prevention is related to the respective punch holes 36 on the side closer to the portion 14d with low rigidity. The sum of the pull-out resistances may be greater than the total.

  Even when there are related punch holes 36 on both sides of the small rigidity portion 14d and a plurality of damage prevention punch holes 38 are provided in the vicinity of the left and right side edges of the game board 14, each damage prevention on the left and right sides is also provided. The sum of the pull-out resistances of the punch holes 38 may be equal to or greater than the sum of the pull-out resistances of the related punch holes 36 on the side closer to the portion 14d having a small rigidity.

  FIG. 13 illustrates a fourth embodiment of the present invention. This embodiment exemplifies a case where game parts such as the big winning means 20 are mounted on the game board 14 with a plurality of press-fitting protrusions 74. In addition to the opening 32 disposed in the game area 9 and the plurality of mounting punch holes 75 disposed in the vicinity of the periphery of the opening 32, the game board 14 is provided on both the left and right sides outside the game area 9. A damage preventing punch hole 38 is arranged. The big winning means 20 has a press-fitting protrusion 74 for attachment on the back side of the outer peripheral flange 39, and is fixed by press-fitting the press-fitting protrusion 74 into the attachment punch hole 75.

  Even in such a case, by providing the damage prevention punch hole 38 outside the game area 9 of the game board 14, as in the first embodiment, when the attachment punch hole 75 is formed, the vicinity of the periphery thereof is formed. Damage to the decorative sheet 13 can be prevented. Therefore, the related punch hole 36 is not limited to the positioning punch hole 41 and the mounting punch hole 43 exemplified in the first embodiment.

  FIG. 14 illustrates a fifth embodiment of the present invention. The diameters of the positioning punch hole 41 and the damage prevention punch hole 38 are made substantially the same, and the depth of the damage prevention punch hole 38 is made larger than the depth of the positioning punch hole 41. Also in this case, since the depth of the damage preventing punch hole 38 is deep, the punch pull-out resistance at the damage preventing punch hole 38 is larger than that at the positioning punch hole 61 side, which is the first embodiment. The same effect as the form can be achieved.

  Accordingly, if the pull-out resistance on the damage prevention punch hole 38 side is larger than the punch pull-out resistance on the other punch holes 41 and 43, the diameter of the damage prevention punch hole 38 is the other punch hole. 41 or 43 may be substantially the same or slightly smaller.

  FIG. 15 illustrates a sixth embodiment of the present invention. In this embodiment, a plurality of damage prevention punch holes 38 are provided in the vicinity of the left edge of the game board 14 so as to avoid the through hole 35. Since the damage preventing punch hole 38 has a larger pulling resistance than the related punch hole 36, when it is provided in the vicinity of the through hole 35, the game board 14 is damaged at the peripheral portion of the through hole 35 by the pulling resistance. Or a predetermined pulling resistance may not be ensured.

  Therefore, it is necessary to arrange the damage preventing punch hole 38 so as to avoid the related punch hole 36. In that case, as shown in FIG. 15, the damage preventing punch holes 38 may be partially spaced as necessary. Further, it is desirable that the damage preventing punch holes 38 be arranged linearly along the pressing member 71, but they may be arranged with their positions slightly changed in the left-right direction.

  FIG. 16 illustrates a seventh embodiment of the present invention. As shown in (a) to (c), the damage preventing punch hole 38 may have a substantially star shape, a substantially oval shape, a substantially rectangular shape, or the like. Further, when a plurality of damage preventing punch holes 38 are provided on the outer peripheral portion, the damage preventing punch holes 38 do not have to have the same shape, and may be appropriately changed according to the conditions of the peripheral portion.

  As mentioned above, although each embodiment of this invention was explained in full detail, this invention is not limited to this each embodiment, A various change is possible in the range which does not deviate from the meaning of this invention. For example, in the embodiment, the pull-out resistance of the gaming nail punch hole 37 that is conical is practically negligible, so that the related punch hole 36 is used for positioning related to the attachment of a gaming part such as the image display means 18. The punch hole 41 and the attachment punch hole 43 are illustrated. However, when the game nail punch hole 37 has a right cylindrical inner peripheral surface, the size and number of damage prevention punch holes 38 on both the left and right sides are determined in consideration of the game nail punch hole 37. do it.

  The left and right damage prevention punch holes 38 may be any one that can accumulate in the game board 14 a force for pulling out the other formation punches 61 and 62 when the damage prevention formation punch 60 is removed from the game board 14. , The force may not be a force necessary to pull out all the forming punches 61 and 62. For example, the sum of the pull-out resistances of the left and right damage prevention punch holes 38 is preferably larger than the sum of the pull-out resistances of the related punch holes 36, but may be slightly smaller than the sum. This is because if the lifting speed of the lifting platform 52 is increased, a large pulling force can be applied to each of the forming punches 61 and 62 by the lifting of the lifting platform 52 immediately thereafter.

  If the sum of the pullout resistance of each damage prevention punch hole 38 is larger than the sum of the pullout resistances of the related punch holes 36, the pullout resistance of each damage prevention punch hole 38 is larger than the pullout resistance of the related punch holes 36. Small.

  The individual pullout resistances in the damage prevention punch holes 38 arranged on the left and right sides of the game board 14 are made substantially the same as the pullout resistances in the other punch holes 41 and 43 distributed in the game area 9. The number of punch holes 38 for damage prevention in the outer peripheral portion is made larger than the number of punch holes 41 and 43 in the game area 9, and the sum of the pullout resistance of the punch holes 38 for damage prevention is the same as that of the punch holes 41 and 43 in the game area 9. You may make it become larger than the sum total of drawing resistance. The material of the game board 14 is not a problem.

  When the plurality of damage prevention punch holes 38 are arranged along the side edge of the game board 14, the damage prevention punch holes 38 are near the edge of the holding member 71 and are substantially parallel to the edge along the edge. It is desirable to arrange the punch holes 38 for use. However, the damage prevention punch holes 38 may be arranged at slightly different positions in the left-right direction depending on the situation around the place where the damage prevention punch holes 38 are arranged.
