  There is a pachinko machine as a representative example of a game machine which plays a game using a game ball. A pachinko machine has a game board in which a game area is formed on the front. The game area is provided with a ball entry portion into which game balls can enter, and when the ball entry into the ball entry portion occurs, for example, whether or not to generate a special game state advantageous to the player The player is provided with benefits such as the lottery and the payout of the game ball.

  In this type of gaming machine, conventional gaming boards are generally produced by sticking a synthetic resin film on which a pattern has been printed on the surface of a wooden plywood (veneer). In recent years, a game board made of synthetic resin is being adopted from the viewpoint of designability and recyclability (for example, Patent Document 1).

  In such pachinko machines, it is common to detachably attach the game board to the pachinko machine main body and to make it possible to replace the game board with the pachinko machine main body if necessary, such as model change. Therefore, in general, the game board is produced through a manufacturing process that is separate from the pachinko machine main body. In the manufacturing process of the synthetic resin game board, first, a nail (obstacle nail) is planted on a synthetic resin game board plate. Then, after attaching small parts, such as a windmill, and a rail member (induction rail) to a plate material, large parts, such as a large winning device and a control circuit board, are assembled. In assembling large parts, the process becomes complicated because the work becomes complicated. Due to the imbalance of the process capability, the game board in the process of manufacture may temporarily stagnate between processes. In such a case, the game boards in the process of manufacture may be temporarily stacked in order to make the stagnated game boards stand by.

In addition, since the height (the vertical direction in FIG. 8) of the outer peripheral edge reinforcing rib 73 is set to a value larger than the thickness of the thick portion 70, the outer side for attaching the game board 30 to the resin base 20 of the main body frame 3 When the rear end of the peripheral reinforcing rib 73 is brought into contact with the front surface of the resin base 20, the thick portion 70 can be prevented from interfering with the resin base 20.

  Referring back to FIG. The thick portion 70 is located substantially at the center on the back side of the game board 30, and the game area PE is formed on the front side of the thick portion 70. Since a nail that interferes with the game ball is implanted in the game area PE, the thick portion 70 is formed substantially at the center of the game board 30 where the game area PE is formed, and the thickness is secured. The holding power of the nail implanted in the part 70 can be secured.

  In addition, since the thickness of the thick portion 70 of the gaming board 30 is set smaller than the height of the outer peripheral reinforcing rib 73, the game of uniform thickness in which the height of the outer peripheral reinforcing rib 73 is the plate thickness It can be lightweight compared to the board. A space can be provided on the back side of the thick portion 70 by the setting of the plate thickness of the thick portion 70 to be smaller than the height of the outer peripheral reinforcing rib 73. Therefore, ornaments and the like are arranged in the space on the back side. It is possible to Since it is also possible to dispose a light emitting element such as an LED in the space on the back side, the rendering effect can be improved.

  Furthermore, since the thin portion 72 having a smaller plate thickness than the thick portion 70 is formed between the thick portion 70 and the outer peripheral reinforcing rib 73, the plate thickness of the thick portion 70 and the plate thickness of the thin portion 72 The amount of synthetic resin can be reduced by the difference between Thereby, the game board 30 can be further reduced in weight. In addition, since a space can be provided on the back side of the thin portion 72 by an amount corresponding to the thickness of the thin portion 72 set smaller than the height of the outer peripheral reinforcing rib 73, a decoration or the like is disposed in the space on the back side. It becomes possible. Since it is also possible to dispose a light emitting element such as an LED in the space on the back side, the rendering effect can be improved.

  Further, since the outer peripheral edge reinforcing rib 73 is erected on the outer peripheral edge of the thin portion 72, the rigidity of the thin portion 72 can be improved, and deformation such as warpage of the thick portion 70 and the thin portion 72 can be prevented. Thereby, the flatness of the board of the game board 30 can be secured.

  An inclined surface portion 71 is formed on the outer periphery of the thick portion 70. The inclined surface portion 71 is set to be gradually smaller in thickness as it goes from the thick portion 70 to the outside, and is connected to the thin portion 72. Thereby, it is possible to suppress the occurrence of deformation due to the difference in thickness between the thick portion 70 and the thin portion 72 when the game board 30 is formed. That is, the game board 30 is molded by melting and filling a synthetic resin in a cavity of a molding die, and after curing, the molded body is taken out from the molding die. Since the cooling rate of the molded body is faster in the thinner portion 72 with a smaller thickness than in the thick portion 70 with a larger thickness, residual stress occurs due to the difference in the cooling rate, and deformation such as warpage is likely to occur in the game board 30 However, the inclined surface portion 71 coupled between the thin portion 72 and the thick portion 70 can buffer the occurrence of residual stress due to the difference in cooling rate. As a result, it is possible to make it difficult for the gaming board 30 to be deformed such as warp.

  The hole 68 formed at the boundary between the thick portion 70 and the inclined surface 71 is a portion into which a fitting pin (described later) spot-welded to the inner rail 32 is inserted. The hole 68 which is located on the outer peripheral side of the game board 30 from the boundary between the thick portion 70 and the inclined surface 71 and formed in the thin portion 72 and the peripheral portion reinforcing rib 73 is spot-welded to the outer rail portion 31. It is a part where a mating pin (described later) is inserted. In the hole 68, a cylindrical protrusion 68a standing from the periphery of the hole 68 toward the rear surface side is provided in a row. The hole 68 penetrates the game board 30 in the thickness direction.

  Since the protrusion 68 a is formed around the hole 68, the plate thickness around the hole 68 can be increased. As a result, since the load per unit area applied by the fitting pin to the inner periphery of the hole 68 can be reduced, it is possible to prevent cracks from occurring around the hole 68 (particularly, the thin portion 72). Further, since the depth of the hole 68 (the front-rear direction of the game board 30) can be increased by the protrusion 68a, the holding force of the fitting pin can be increased. Thereby, the outer rail portion 31 and the inner rail portion 32 can be firmly fixed to the board of the game board 30.

  Further, a protrusion 68a (hole 68) into which the fitting pin spot-welded to the inner rail 32 is inserted is formed at the boundary between the thick portion 70 and the inclined surface 71, and the thickness of the protrusion 68a is increased. The portion 70 and the inclined surface portion 71 are provided in series. Since the plate thickness of the thick portion 70 and the inclined surface portion 71 is larger than the plate thickness of the thin portion 72, the projection length of the projection 68 a with respect to the thick portion 70 and the inclined surface portion 71 is greater than the projection length of the projection 68 a with respect to the thin portion 72 It can be made smaller. As a result, the bending moment of the projecting portion 68 a with respect to the thick portion 70 and the inclined surface portion 71 can be made smaller than the bending moment of the projecting portion 68 a with respect to the thin portion 72. The bending strength of 68 a can be improved more than the bending strength of the protrusion 68 a provided in the thin portion 72.

  In addition, a fitting pin spot-welded to the inner rail portion 32 is inserted into the hole 68 formed in the projecting portion 68 a formed at the boundary between the thick portion 70 and the inclined surface 71. By providing the thick portion 70 on the inner side of the inner rail portion 32 in which the game area PE is formed, the holding power of nails, a windmill, etc. can be secured. The area of the thick portion 70 is excessive by providing a projection 68a (hole 68) into which the fitting pin spot-welded to the inner rail 32 is inserted at the boundary between the thick portion 70 and the inclined surface 71. Can be prevented from increasing. By not enlarging the thick portion 70 outside the area (inside the inner rail portion 32) where the game area PE is formed, the amount of synthetic resin forming the game board 30 is reduced, and the mass of the game board 30 is increased. It can be prevented from becoming larger than necessary.

  The out port 39 is formed at the boundary between the thick portion 70 and the inclined surface portion 71 at the lower position of the gaming board 30 and penetrates in the thickness direction of the gaming board 30. A reinforcing rib 39a is erected toward the back side around the out port 39, and the reinforcing rib 39a is integrally formed with the game board 30. The reinforcing rib 39a forms a passage for gaming balls having entered the out slot 39 from the gaming area PE, and can reinforce the periphery of the out slot 39 to improve rigidity.

  The hole 69 is a portion into which the fitting convex portion 55 (to be described later) of the guide portion reinforcing member 50 is inserted and is formed to penetrate the thin portion 72. Since the protrusion 69 a is formed around the hole 69, the plate thickness around the hole 69 can be increased. As a result, the load per unit area applied by the fitting convex portion to the inner periphery of the hole 69 can be reduced, so that it is possible to prevent the occurrence of cracks around the hole 69 (thin portion 72). Further, since the depth of the hole 69 (the front-rear direction of the game board 30) can be increased by the projection 69a, the holding power of the fitting projection 55 can be increased. Thus, the guide portion reinforcing member 50 can be firmly fixed to the board of the game board 30.

  In the outer peripheral edge reinforcing rib 73, recessed portions 73a, 73b, 73c are formed in which a part of the end face on the back side (the front side in FIG. 7) is recessed in the height direction (the height of the rib is lowered). . Recesses 73a and 73c are formed at opposite positions of outer peripheral edge reinforcing ribs 73 (left and right ribs), and recessed portion 73b intersects outer peripheral edge reinforcing ribs 73 (left and right ribs) in which recessed portions 73a and 73c are formed. It is formed in the outer periphery reinforcing rib 73 (lower rib). Since the recessed portions 73a and 73c are formed at the opposing positions of the outer peripheral reinforcing ribs 73, the outer peripheral reinforcing ribs 73 are directed downward onto the table having the flat surface formed on the upper surface thereof. In the case where the rear surface is turned downward, a gap is formed between the flat surface and the game board 30 (the outer peripheral edge reinforcing rib 73) by the amount of the recessed portions 73a and 73c. A fingertip or the like of a hand can be inserted into the gap, and the gaming board 30 placed on the flat surface can be lifted using the inserted fingertip or the like as a clue.

  On the other hand, when the recessed portions 73a, 73b and 73c are not formed on the end face of the outer peripheral surface reinforcing rib 73 on the back surface side, the outer peripheral reinforcing rib 73 is lowered on a table having a flat surface on the upper surface. When the game board 30 is placed facing the rear side (the rear side faces down), the entire circumference of the rear side end face of the outer peripheral reinforcing rib 73 is in close contact with the flat surface (no gap is formed). In that case, since it is difficult to insert a fingertip or the like between the outer peripheral reinforcing rib 73 and the flat surface (base), there arises a problem that it is difficult to lift the game board 30. According to the present embodiment, this problem can be solved by forming the recessed portions 73 a, 73 b and 73 c in the outer peripheral edge reinforcing rib 73.

  The openings 62 are through holes to which the projecting pins 60 are attached, and are formed at two diagonal positions of the game board 30. A reinforcing rib 62a is erected toward the back side around the opening 62, and the reinforcing rib 62a is connected to the outer peripheral wall reinforcing rib 62a.

  The heights of the reinforcing ribs 39a and 62a and the protrusions 68a and 69a are set to be substantially the same as the height of the peripheral edge reinforcing rib 73. Thus, with the gaming board 30 being placed with the outer peripheral reinforcing rib 73 facing downward (the back side facing down) on the table having the flat surface formed on the upper surface, When a load is applied to the front surface, the load can be received by the reinforcing ribs 39a and 62a, the protrusions 68a and 69a, and the peripheral edge reinforcing rib 73.

  On the other hand, when the reinforcing ribs 39a and 62a and the projecting portions 68a and 69a are not formed, when the game board 30 receives a load from the board surface, bending deformation occurs in the thick portion 70 and the thin portion 72. When the deformation is large, the vicinity of the boundary between the peripheral portion reinforcing rib 73 and the thin portion 72 may be broken. According to the present embodiment, by setting the heights of the reinforcing ribs 39a and 62a and the projecting portions 68a and 69a to be substantially the same as the height of the peripheral portion reinforcing rib 73, the thick portion 70 and the thin portion can be thin Since the occurrence of bending deformation in the portion 72 can be suppressed, this problem can be solved.

  In particular, since the protrusions 68a for fixing the outer rail portion 31 and the inner rail portion 32 are located on a substantially semicircular line and widely dispersed on the game board 30, a specific location on the board of the game board 30 Even when the concentrated load is applied to the game board, it is possible to prevent the occurrence of a large bending deformation on the board of the game board 30. This makes it possible to prevent the game board 30 from being damaged by the load applied to the game board 30 when a nail is planted on the game board 30 or various game components are attached.

  The opening 62 and the projecting pin 60 will now be described with reference to FIG. FIG. 9 is an end view of the cutting portion of the game board 30 taken along line IX-IX in FIG. As shown in FIG. 9, the projecting pin 60 is a substantially cylindrical member formed of a separate member from the gaming board 30, and includes a collar 60a projecting in the radial direction (the left and right direction in FIG. 9) from the outer peripheral surface. A fitting and inserting portion 60b extending from the collar portion 60a to the other side in the axial direction is provided in a row. The insertion portion 60b is a portion to be inserted into the opening 62, and the collar portion 60a is a portion for regulating the insertion depth of the insertion portion 60b to be inserted into the opening 62. On the other hand, on the surface of the game board 30, a recessed portion 62b for receiving the hook 60a is formed. The recessed portion 62 b is continuously provided around the opening 62 at a depth substantially the same as the thickness of the flange portion 60 a. The diameter of the protruding pin 60 is slightly smaller than the diameter of the insertion portion 60b (the inner diameter of the opening 62).

  The end face of the reinforcing rib 62a on the back side (the lower side in FIG. 9) is set at the same height position as the end face on the back side (the lower side in FIG. 9) of the peripheral edge reinforcing rib 73. Thus, the depth (vertical direction in FIG. 9) of the opening 62 can be increased, so that the insertion depth of the insertion portion 60b inserted into the opening 62 can be increased. On the other hand, when the reinforcing rib 62 a is not formed, the depth of the opening 62 is the same as the thickness of the thin portion 72. In that case, compared with the present embodiment, the holding force for holding the insertion portion 60b in the opening 62 becomes smaller, and the protrusion pin 60 is easily rattled or detached. By providing the reinforcing rib 62a as in the present embodiment, this can be prevented.

  In addition, since the gaming board 30 in which the fitting and inserting portion 60b is inserted into the opening 62 has the hook portion 60a, the projecting pin 60 protrudes from the face of the gaming board 30 by a predetermined length. On the other hand, the reinforcing rib 62a is set on the back surface side (the lower side in FIG. 9) so as to form a depression (hole) deeper than the projection length of the projecting pin 60 from the plate surface. The diameter of the projecting pin 60 is formed slightly smaller than the diameter of the insertion portion 60b (the inner diameter of the opening 62), so when a plurality of gaming boards 30 are stacked, from the board surface of one gaming board 30 The protruding protruding pin 60 is inserted into the recess (hole) in the reinforcing rib 62 a from the back side of the other gaming board 30. As a result, it is possible to prevent the positional deviation of the game board 30 stacked in the flat state in the direction of the board surface.

  In addition, by forming the projecting pin 60 as a separate member from the gaming board 30 as in the present embodiment, after the gaming board 30 is formed, the gaming board is engaged until the projecting pin 60 is fitted to the opening 62. The projecting pins 60 can be made not to protrude from the plate surface 30. As a result, after the game board 30 is formed, the projection pins 60 prevent the transportation of the game board 30 from being interrupted or the projection pins 60 are broken until the projection pins 60 are fitted into the opening 62. it can. Further, after the projecting pin 60 is fitted to the opening 62, if the projecting pin 60 is not necessary when assembling the pachinko machine 1 or the like, the projecting pin 60 can be removed from the opening 62. Thereby, assembly etc. of the pachinko machine 1 can be performed smoothly.

  In addition, it is possible to form the projecting pins 60 integrally with the gaming board 30 when the gaming board 30 is formed. When the projecting pin 60 is fitted (inserted) into the game board 30 as in the present embodiment, it is necessary to prepare the projecting pin 60 as a separate member and insert the projecting pin 60 into the game board 30. On the other hand, by forming the projecting pin integrally with the game board, it is not necessary to prepare the projecting pin 60 as a separate member, so that the number of parts can be reduced. Further, the work of inserting the projecting pin 60 into the game board 30 can be made unnecessary.

  FIG. 10 is a schematic view showing a state in which a plurality of game boards 30 are stacked. The game board 30 is integrally molded by melting and filling a synthetic resin in a molding die, and an outer peripheral edge reinforcing rib 73 is provided upright on the back side of a flat board surface (front side). When the game boards 30 made of synthetic resin are stacked and transported, there is a problem that the position is shifted and it is easy to slide off as compared with the case where the conventional game boards made of wooden plywood are stacked and transported. The game board 30 made of synthetic resin is slippery because the surface smoothness of the board is high and the coefficient of friction is small as compared with the game board made of wooden plywood.

  On the other hand, according to the present embodiment, the game board 30 is stacked by inserting the projecting pin 60 of one game board 30 into a recess (hole) in the reinforcing rib 62 a of the other game board 30. It can be easily transported. In addition, since it is easy to insert a fingertip or the like into the gap formed by the recess 73a formed on the end face of the outer peripheral reinforcing rib 73, the game board 30 can be easily lifted. Further, since the recessed portions 73a and 73c are formed at the opposing positions of the outer peripheral edge reinforcing rib 73, it is possible to lift in a well-balanced manner by inserting the fingertips or the like of the hand from the left and right into the recessed portions 73a and 73c. Furthermore, since the recessed portion 73b is formed in the outer peripheral edge reinforcing rib 73 (located below FIG. 7) intersecting the outer peripheral edge reinforcing rib 73 (located at the right and left in FIG. 7) where the recessed portions 73a and 73c are formed. The game board 30 can be supported from three sides of the game board 30, and the game board 30 can be transported in a well-balanced manner.

  Next, the guide portion reinforcing member 50 will be described with reference to FIGS. 11 to 14. 11 is a partially enlarged front view of the game board 30 to which the guide portion (outer rail portion 31) and the guide portion reinforcing member 50 are fixed, FIG. 12 is a partially enlarged rear view thereof, and FIG. FIG. The guide portion reinforcing member 50 is a member for preventing the outer rail portion 31 on which the game ball launched from the game ball launch device 21 first collides from swinging. By the guide portion reinforcing member 50 being applied to the outer rail portion 31, swinging of the outer rail portion 31 is prevented. As a result, the trajectory of the game ball and the flight distance of the game ball to the game area PE can be stabilized.

  First, the outer rail portion 31 will be described with reference to FIG. The outer rail portion 31 is formed of a band-shaped thin plate made of metal (stainless steel), and fitting pins 31a are spot-welded at side edges in the longitudinal direction of the outer rail portion 31 with an appropriate interval. The outer rails 31 are erected on the game board 30 by inserting the fitting pins 31 a into the holes 68 formed in the game board 30.

  Further, the outer rail portion 31 is provided with a bent portion 31 b which is bent in a longitudinal end edge and turned back into a substantially U shape. The bent portion 31b is a portion for preventing the end edge of the outer rail portion 31 in the longitudinal direction from swinging, and a guide of the outer rail portion 31 to which the game ball fired from the game ball launching device 21 is guided. It is bent to the opposite surface side (rear surface side) of the surface 31c. Thereby, when the game ball fired from the game ball launching device 21 collides with the guide surface 31c of the outer rail portion 31, the edge of the outer rail portion 31 tilts to the opposite surface side (back side) of the guide surface 31c. Can be prevented.

  The guide portion reinforcing member 50 is provided at a position where the fitting pin 31 a is disposed between the bent portion 31 b and the guide portion reinforcing member 50. That is, the guide portion reinforcing member 50 is disposed between the fitting pins 31a. Since the fitting pins 31a are fixed to the outer rail portion 31 at appropriate intervals, the outer rail portion 31 is likely to swing between the fitting pins 31a. However, by arranging the guide portion reinforcing member 50 between the fitting pins 31a, it is possible to suppress the outer rail portion 31 from swinging between the fitting pins 31a.

  Next, the detailed configuration of the guide portion reinforcing member 50 will be described. As shown in FIGS. 11 and 13, the guide portion reinforcing member 50 is a member made of a synthetic resin, and formed in a substantially trapezoidal shape (as viewed from the side of the board of the game board 30) as viewed from the front 31. A base 51 positioned on the side opposite to the guide surface 31c, an opposite side projection 52 erected on the base 51, and a direction in which the opposite side projection 52 is erected. It is mainly provided with the fitting convex part 55 protrudingly provided from the base | substrate part 51 in the opposite direction.

  The base portion 51 is a plate-like portion that is in close contact with the surface of the game board 30 and disposed along the outer rail portion 31, and the opposite surface side protruding portion 52 stands substantially vertically to the base portion 51. It is a portion provided in the form of a wall at the edge of the base portion 51 as well as being provided. The opposite surface side projecting portion 52 is provided along the outer rail portion 31, and the base portion 51 is extended at the rear end side in the direction away from the outer rail portion 31. As a result, the base portion 51 and the opposite surface side protruding portion 52 are formed in a substantially L-shape in a side view.

  The opposite surface side projecting portion 52 is connected to the inclined portion 52a which is inclined downward from the top toward the base portion 51 side (panel surface side), and is connected to the inclined portion 52a and faces the outer rail portion 31 to at least one. And a contact portion 52b with which the portion contacts. A fitting convex portion 55 is provided in a projecting manner at one side edge of the base portion 51 and the opposite surface side projecting portion 52. Further, a rod-like columnar portion 53 is provided upright along the opposite surface side protruding portion 52 at the other side edge opposed to one side edge of the base portion 51 and the opposite surface side protruding portion 52. The columnar portion 53 is a portion for improving the bending rigidity of the opposite surface side protruding portion 52, is integrally formed with the base portion 51 and the opposite surface side protruding portion 52, and is located on the back surface side of the contact portion 52b. Thereby, compared with the thing in which the columnar part 53 is not formed, it can be made hard to bend and deform the opposite surface side projecting part 52 with respect to the axial direction of the columnar part 53. FIG.

  In the present embodiment, the columnar part 53 is formed in a cylindrical shape in which a hole (vertical hole 53 a) is formed substantially at the center along the axis of the columnar part 53. By forming the columnar portion 53 in a cylindrical shape in which the vertical hole portion 53a is formed, the torsional rigidity is improved as compared with a solid columnar portion (having the same outer diameter) in which the vertical hole portion 53a is not formed. At the same time, the columnar part 53 can be reduced in weight. As a result, as compared with the case where the columnar portion is formed in a solid shape in which the vertical hole portion 53a is not formed, the mass is excessively increased while the torsional rigidity of the opposite surface side projecting portion 52 is improved (hard to be deformed). Can be prevented.

  The columnar portion 53 has a substantially triangular reinforcing portion 54 extending in the axial direction of the outer peripheral edge. The reinforcing portion 54 is a member for reinforcing the columnar portion 53, and is set so that the cross-sectional area gradually increases from the top side toward the bottom side, and the bottom is set to be in close contact with the board of the game board 30. Ru. Since the substantially triangular reinforcing portion 54 is extended to the columnar portion 53 and the bottom of the columnar portion 53 is set in close contact with the surface of the game board 30, the columnar portion 53 can be further hardly bent and deformed.

  The base portion 51 is set such that the length of one side edge where the fitting convex portion 55 is provided is shorter than the length of the other side edge facing the one side edge. Since the other side edge of the base portion 51 is continuously provided on the bottom side of the columnar portion 53 and the reinforcing portion 54, the bottom area of the base portion 51 is gradually increased from one side edge to the other side edge of the base portion 51. It is set to become. By making the bottom area of the base 51 at a position far from the fitting projection 55 larger than the bottom area of the base 51 at a position near the fitting projection 55, the bottom of the position away from the fitting projection 55 Insufficient area can be prevented. As a result, it is possible to suppress the swing of the opposite surface side projecting portion 52 at a position far from the fitting convex portion 55.

  In addition, since the guide portion reinforcing member 50 is provided with the base portion 51 disposed along the outer rail portion 31, as shown in FIG. Can be shifted to the end (bent portion 31 b) side of the outer rail portion 31. As a result, the position of the fitting pin 31a for fixing the outer rail portion 31 to the game board 30 can be brought close to the position of the opposite surface side projecting portion 52 (contact portion 52b). By bringing the contact portion 52b closer to the fitting pin 31a for fixing the outer rail portion 31, it is possible to make the outer rail portion 31 less likely to bend between the fitting pin 31a and the contact portion 52b. As a result, the outer rail portion 31 can be effectively reinforced by the guide portion reinforcing member 50.

  The fitting convex portion 55 is a portion fitted to the hole 69 formed in the game board 30 in order to fix the guide portion reinforcing member 50 to the game board 30, and in the present embodiment, it is substantially circular. It is formed in a columnar shape. The fitting convex portion 55 is formed with a rounded reduced diameter portion 55a at its tip. The reduced diameter portion 55a is a portion set so that the area of the cross section orthogonal to the axis gradually decreases toward the tip end. Since the reduced diameter portion 55 a is formed, the fitting convex portion 55 can be easily inserted into the hole 69. Further, since the fitting convex portion 55 and the hole portion 69 are formed in a substantially circular shape in cross section, the fitting convex portion 55 can be made rotatable relative to the hole portion 69, and the guide portion reinforcing member 50 can be obtained. Fine positional adjustment when inserting into the hole 69 can be omitted. As a result, the workability of the operation of inserting the guide portion reinforcing member 50 into the hole portion 69 can be improved.

  The fitting convex portion 55 will be described with reference to FIG. FIG. 12 is a partially enlarged rear view of the game board 30 on which the guide portion (outer rail portion 31) and the guide portion reinforcing member 50 are installed. In FIG. 12, the position of the outer rail portion 31 disposed on the board of the game board 30 is illustrated by an imaginary line (two-dot chain line).

  As shown in FIG. 12, the fitting protrusion 55 includes a recess 56 in which a part of the outer peripheral surface is formed in a recess. Since a part of the outer peripheral surface of the fitting convex portion 55 is formed in a recessed shape by the concave portion 56, when the fitting convex portion 55 is fitted to the hole 69, the outer peripheral surface of the fitting convex portion 55 and the hole 69 The contact area with the inner circumferential surface of can be reduced. As a result, it is possible to increase the vertical effectiveness per unit area of the hole 69 and the fitting convex portion 55 when the fitting convex portion 55 is fitted in the hole 69. As a result, when fitting the fitting convex portion 55 into the hole 69, the hole 69 or the fitting convex portion 55 can be easily deformed (elastically or plastically deformed). The hole 69 can be easily fitted.

  Further, since the concave portion 56 is formed along the axial direction of the fitting convex portion 55, the effect of the concave portion 56 described above can be obtained along the axial direction of the fitting convex portion 55. Furthermore, since the recess 56 is formed from the distal end to the proximal end of the fitting projection 55, the effect of the recess 56 can be obtained from the distal end to the proximal end of the fitting projection 55.

  In the present embodiment, the concave portion 56 is formed in a slip shape from the tip end of the fitting convex portion 55 toward the proximal end. As a result, the fitting convex portion 55 can be fitted in the hole 69 by utilizing the elastic deformation of the fitting convex portion 55 due to the abrasion. Thereby, the fitting convex portion 55 can be easily fitted into the hole 69. Furthermore, by utilizing the elastic deformation of the fitting convex portion 55, it is possible to prevent a gap from being generated between the hole 69 and the fitting convex portion 55. As a result, it is possible to prevent the fitting convex portion 55 fitted in the hole 69 from rattling.

  Furthermore, in the present embodiment, the rubbing direction of the recess 56 as viewed from the axial direction (vertical direction in FIG. 12) of the fitting convex portion 55 is disposed non-parallel to the longitudinal direction of the outer rail portion 31. Thereby, when the guide surface 31c is pushed to the opposite surface side (the lower side in FIG. 12) by the gaming ball advancing toward the game area PE along the guide surface 31c of the belt-like outer rail portion 31, the fitting convex It is possible to make elastic deformation of the portion 55 difficult. This makes it difficult to tilt the guide portion reinforcing member 50.

  That is, the fitting convex portion 55 is unlikely to be elastically deformed by a load parallel to the rubbing direction, and is easily elastically deformed by a load orthogonal to the rubbing direction. When a load parallel to the rubbing direction is applied to the fitting convex portion 55, the fitting convex portion 55 is deformed so as to reduce the gap of the slit-like concave portion 56. Therefore, if the guide portion reinforcing member 50 is arranged such that the direction of friction of the fitting convex portion 55 is parallel to the longitudinal direction of the outer rail portion 31, the guide surface 31c of the outer rail portion 31 is pushed to the opposite side. When being done, the outer rail portion 31 tends to tilt due to the elastic deformation of the fitting convex portion 55. On the other hand, if the guide portion reinforcing member 50 is arranged such that the direction of the slip of the fitting convex portion 55 is not parallel to the longitudinal direction of the outer rail portion 31, the guide surface 31c of the outer rail portion 31 is the opposite surface. When pressed to the side, the fitting convex portion 55 can be made difficult to elastically deform. This makes it difficult to tilt the guide portion reinforcing member 50.

  In particular, by making the longitudinal direction of the outer rail portion 31 orthogonal to the rubbing direction of the concave portion 56, the fitting convex portion 55 can be most hardly elastically deformed by a load parallel to the rubbing direction. Thereby, as the outer rail portion 31 tilts, it is possible to suppress the guide portion reinforcing member 50 from tilting together. As a result, tilting of the outer rail portion 31 can be suppressed as the gaming ball advances, and the trajectory and flight distance of the gaming ball proceeding along the outer rail portion 31 can be stabilized.

  By making the longitudinal direction of the outer rail portion 31 and the direction of abrasion of the concave portion 56 non-orthogonal, it is possible to utilize elastic deformation of the fitting convex portion 55 by a load parallel to the direction of abrasion. is there. In particular, by making the longitudinal direction of the outer rail portion 31 parallel to the rubbing direction of the concave portion 56, it is possible to most actively utilize the elastic deformation of the fitting convex portion 55. As the outer rail portion 31 is tilted due to the progress of the game ball, the guide portion reinforcing member 50 (opposite surface side protruding portion 52) is tilted together to elastically deform the fitting convex portion 55, and the fitting convex portion 55 By the restoring force, it is possible to restore the guide portion reinforcing member 50 (opposite surface side protruding portion 52) and the outer rail portion 31 to their original positions. By utilizing the elastic deformation of the fitting convex portion 55, it is possible to suppress that the guide portion reinforcing member 50 is broken by the load (the load by the game ball) which is repeatedly input. As a result, it is possible to suppress that the guiding portion reinforcing member 50 can not restrict the tilting of the outer rail portion 31, and it is possible to stabilize the trajectory and the flight distance of the gaming ball traveling along the outer rail portion 31.

  Further, in the fitting convex portion 55, a concave portion 56a having a substantially circular cross section continuously formed with the concave portion 56 is formed at substantially the center of the fitting convex portion 55 along the axis (vertical direction in FIG. 12). ing. Since the concave portion 56a is formed, the cross-sectional area of the approximate center (near the axis) of the fitting convex portion 55 can be reduced. Thereby, the cross-sectional shape of the fitting convex part 55 of the both sides of the recessed part 56 in an axial direction view can be made into substantially fan shape. As a result, when a load parallel to the rubbing direction is applied to the fitting convex portion 55, the fitting convex portion 55 can be deformed so as to reduce the cross-sectional area of the recessed portion 56a. Thereby, the fitting convex part 55 can be fitted in the hole 69 by utilizing the elastic deformation of the fitting convex part 55 due to the concave portion 56a. Thereby, the fitting convex portion 55 can be easily fitted into the hole 69.

  The amount of elastic deformation of the fitting projection 55 due to the recess 56a is smaller than the amount of elastic deformation of the fitting projection 55 due to the recess 56. Therefore, the fitting projection in the rubbing direction (approximately vertical direction in FIG. 12) The amount of elastic deformation of 55 can be made different from the amount of elastic deformation of the fitting convex portion 55 in the direction (generally the left and right direction in FIG. 12) orthogonal to rubbing. Specifically, the elastic deformation amount of the fitting convex portion 55 in the rubbing direction (the substantially vertical direction in FIG. 12) is the elastic deformation of the fitting convex portion 55 in the direction orthogonal to the rubbing (the substantially horizontal direction in FIG. 12). It can be smaller than the amount. Therefore, it is possible to prevent loss of the effect of making it difficult to tilt the guide portion reinforcing member 50 when the recessed portion 56a is formed.

  In the end face of the projecting portion 68a in which the fitting pin 31a fixed to the outer rail portion 31 is inserted in the hole 68, a part of the end face is recessed from the hole 68 (inner peripheral surface) to the outer peripheral surface An end face groove 68b is formed. The end face grooves 68 b are formed in a direction along the longitudinal direction of the outer rail portion 31 disposed on the board surface of the game board 30. Since the end face groove 68b is formed on the end face of the projecting portion 68a, when the outer rail portion 31 is disposed on the game board 30, it is possible to make the direction in which the outer rail portion 31 is disposed erroneous.

  Referring back to FIG. As shown in FIG. 11, the guide portion reinforcing member 50 is disposed on the guide surface 31 c side of the outer rail portion 31 so as to face the opposite surface side projecting portion 52 and to be in contact with the guide surface 31 c. A section 57 is provided. As shown in FIG. 11 and FIG. 13, the guide surface side projecting portion 57 is projectingly provided on a part in the axial direction of the base end side (the front side in FIG. 11) of the fitting convex portion 55. A groove portion 58 into which the outer rail portion 31 is inserted is formed between the guide surface side projecting portion 57 and the opposite surface side projecting portion 52.

  Next, with reference to FIG. 14, the guide surface side projecting portion 57 and the groove portion 58 will be described. FIG. 14 is a cross-sectional view of the game board 30 taken along line XIV-XIV of FIG. As shown in FIG. 14, the guide surface side projecting portion 57 is disposed facing the opposite surface side projecting portion 52 at an interval substantially equal to the thickness of the outer rail portion 31. The opposite surface side projecting portion 52 is set to a height substantially the same as the height of the outer rail portion 31, but the guiding surface side projecting portion 57 is set to be lower than the height of the opposite surface side projecting portion 52 There is. Specifically, the height is set so as not to interfere with the game ball B moving along the outer rail portion 31.

  Since the guide portion reinforcing member 50 includes the guide surface side projecting portion 57, the outer rail portion 31 is held in the groove portion 58 between the opposite surface side projecting portion 52 and the guide surface side projecting portion 57. Since the outer rail portion 31 is held from both sides by the opposite surface side projecting portion 52 of the guide portion reinforcing member 50 and the guide surface side projecting portion 57, tilting of the outer rail portion 31 can be reliably prevented.

  Further, since the guide surface side projecting portion 57 disposed on the guide surface 31c side of the outer rail portion 31 is set to be lower than the height of the opposite surface side projecting portion 52, the game ball B along the guide surface 31c The guide surface side projecting portion 57 does not disturb the movement of the guide surface. When the game ball B interferes with the guide surface side projecting portion 57, a loss of kinetic energy of the game ball B occurs and the flight distance of the game ball B guided to the game area PE becomes unstable, but this can be prevented. The flight distance of the game ball B guided to the game area PE can be prevented from becoming unstable.

  In addition, as shown in FIG. 14, the concave portion 56 is scraped from the tip end (lower side in FIG. 14) of the fitting convex portion 55 while leaving the base end (base end 55 b) of the solid fitting convex portion 55. It is formed. Thus, the base end 55b of the solid fitting projection 55 can be fitted into the hole 69 (panel side). By fitting the base end 55b of the solid fitting convex portion 55 into the hole 69 (panel surface side), it is possible to prevent the rattling of the fitting convex portion 55 from occurring with respect to the hole 69. Furthermore, since the concave portion 56 is formed on the tip end side of the fitting convex portion 55, the elastic deformation or plastic deformation of the fitting convex portion 55 or the hole 69 can be facilitated, and the fitting convex portion 55 can be made into the hole 69 can be easily fitted.

  The gap between the outer peripheral surface of the fitting convex portion 55 (base end portion 55b) and the hole 69 is held by the groove 58 between the opposite surface side projecting portion 52 and the guide surface side projecting portion 57. The clearance is set to a smaller value than the clearance between the rail portion 31 and the opposite surface side projecting portion 52 or the guiding surface side projecting portion 57. When the outer rail portion 31 is fixed to the game board 30 while preventing rattling of the fitting convex portion 55 (base end portion 55b) inserted into the hole portion 69, the opposite surface side projecting portion 52 and the guide This is to facilitate the insertion of the outer rail portion 31 into the groove portion 58 between the surface side protruding portions 57. Since the outer rail portion 31 is fixed to the game board 30 by the fitting pins 31a even if a gap is formed between the opposite surface side protruding portion 52 or the guide surface side protruding portion 57 and the outer rail portion 31, The rattling of the outer rail portion 31 with respect to the game board 30 can be prevented.

  As described above, the guide portion reinforcing member 50 for restricting the tilting of the outer rail portion 31 has the fitting convex portion 55 fitted in the hole portion 69 formed in the recess shape on the board surface of the game board 30, and the fitting convex portion thereof. An opposite surface side projecting portion 52 is provided to project from the portion 55 and to be in contact with the opposite surface side of the guide surface 31 c of the outer rail portion 31. In the guide portion reinforcing member 50, an opposite surface side projecting portion in which the fitting convex portion 55 is fitted in the hole portion 69 formed in a depression shape on the surface of the game board 30, and the projecting portion 55 is provided. 52 contacts the opposite surface side of the guide surface 31 c of the outer rail portion 31. Accordingly, it is possible to suppress the belt-like outer rail portion 31 from being tilted outward by the guide surface 31c being pushed to the opposite surface side by the gaming ball advancing toward the game area PE along the guide surface 31c. Since tilting of the outer rail portion 31 for guiding the game balls to the game area PE can be suppressed, it is possible to stabilize the trajectory and the flight distance of the game balls guided to the game area PE.

  That is, when the guide surface 31c is pushed to the opposite surface side by the game ball advancing toward the game area PE along the guide surface 31c and the belt-like outer rail portion 31 tilts, the trajectory of the game ball changes or the game ball Loss of kinetic energy occurs. As a result, the trajectory and flight distance of the gaming ball guided to the gaming area PE may be unstable.

  On the other hand, according to the present embodiment, the guide surface reinforcing member 50 is disposed such that the opposite surface side protruding portion 52 is in contact with the surface opposite to the surface 31c of the outer rail portion 31. It is possible to suppress tilting of the outer rail portion 31 by the game balls advancing toward the game area PE along 31c. This makes it possible to stabilize the trajectory and flight distance of the gaming ball guided to the gaming area PE.

  In addition, since the fitting convex portion 55 includes the concave portion 56 in which a part of the outer peripheral surface is formed in a dent shape, the fitting convex portion 55 when the fitting convex portion 55 is fitted in the hole 69 The contact area between the outer peripheral surface and the inner peripheral surface of the hole 69 can be reduced. As a result, it is possible to increase the vertical effectiveness per unit area of the hole 69 and the fitting convex portion 55 when the fitting convex portion 55 is fitted in the hole 69. As a result, when fitting the fitting convex portion 55 into the hole 69, the hole 69 or the fitting convex portion 55 can be easily deformed (elastically or plastically deformed). The hole 69 can be easily fitted.

  In addition, since the concave portion 56 is formed in a shape of rubbing from the tip end of the fitting convex portion 55 toward the base end (proximal end portion 55b), using elastic deformation of the fitting convex portion 55 due to rubbing. The fitting protrusion 55 can be fitted in the hole 69. As a result, the fitting convex portion 55 can be easily fitted into the hole 69, and by utilizing elastic deformation of the fitting convex portion 55, generation of a gap between the hole 69 and the fitting convex portion 55 is prevented. Since this can be done, it is possible to make the fitting convex portion 55 fitted in the hole 69 less likely to rattle.

  In addition, since the direction of abrasion of the concave portion 56 viewed from the axial direction of the fitting convex portion 55 is disposed not in parallel with the longitudinal direction of the outer rail portion 31, along the guide surface 31 c of the belt-like outer rail portion 31 When the guide surface 31c is pushed to the opposite surface side by the game ball advancing toward the game area PE, the fitting convex portion 55 can be made difficult to elastically deform. Thereby, tilting of the outer rail portion 31 can be suppressed. As a result, it is possible to further stabilize the trajectory and flight distance of the gaming ball guided to the gaming area PE.

  Further, since the guide portion reinforcing member 50 is provided with the guide surface side projecting portion 57 facing the opposite surface side projecting portion 52, the outer rail portion 31 is held from both the guide surface 31c and the opposite surface. Thereby, tilting of the outer rail portion 31 can be reliably prevented. As a result, it is possible to further stabilize the trajectory and flight distance of the gaming ball guided to the gaming area PE. Furthermore, since the guide surface side projecting portion 57 is set to be lower than the height of the opposing surface side projecting portion 52 facing each other, interference between the game ball and the guide surface side projecting portion 57 along the guide surface 31 c is prevented. it can.

  Further, the opposite surface side protruding portion 52 is connected to the inclined portion 52a which is inclined downward from the top toward the axial direction outer side of the fitting convex portion 55, and the inclined portion 52a and the opposite surface of the outer rail portion 31. Since it is provided with the contact part 52b which at least one part of an opposite surface contacts while facing it, the operation | work which arrange | positions the guide part reinforcement member 50 and the outer rail part 31 on the board surface of the game board 30 can be facilitated.

  That is, when arranging the guide portion reinforcing member 50 and the outer rail portion 31 on the board surface of the game board 30, first, about half the length of the fitting convex portion 55 of the guide portion reinforcing member 50 Insert in the hole 69. Since the concave portion 56 is formed in the fitting convex portion 55 in a slip shape, the fitting convex portion 55 is formed so as to narrow the gap between the concave portions 56 when inserted into the hole 69 of the game board 30. Deform. Therefore, the operation of inserting about half of the length of the fitting projection 55 into the hole 69 of the game board 30 can be facilitated.

  Next, the outer rail portion 31 is disposed along the inclined portion 52 a of the opposite surface side protruding portion 52 so that the outer rail portion 31 faces the contact portion 52 b of the guide portion reinforcing member 50. The inclined portion 52a is inclined downward from the top toward the axial direction outer side of the fitting convex portion 55, and the contact portion 52b is provided continuously with the inclined portion 52a, so the outer rail portion 31 is formed along the inclined portion 52a. Can be smoothly disposed to the contact portion 52b.

  When the outer rail portion 31 is moved in a direction perpendicular to the board surface of the game board 30 to bring the outer rail portion 31 closer to the game board 30, if the side edge of the outer rail portion 31 abuts the inclined portion 52a, the outer rail As the section 31 approaches the game board 30, the inclined part 52a is pushed in the horizontal direction with respect to the board surface, and the guiding part reinforcing member 50 rotates around the fitting convex part 55. When the outer rail portion 31 separates from the inclined portion 52a and faces the contact portion 52b, no force for rotating the guide portion reinforcing member 50 is generated, so the position of the guide portion reinforcing member 50 is determined.

  Further, while fitting the outer rail portion 31 in the groove portion 58 between the contact portion 52b and the guide surface side protruding portion 57, the fitting pin 31a fixed to the outer rail portion 31 is inserted into the hole portion 68. Go. As the fitting pin 31a is inserted into the hole 68, the base end face of the fitting protrusion 55 is pushed to the side edge of the outer rail portion 31, and the fitting protrusion 55 is gradually fitted into the hole 69 . Thereby, the workability of the arrangement operation of arranging the outer rail portion 31 on the board of the game board 30 can be improved.

  In addition, since the base end 55 b of the fitting convex portion 55 is formed in a solid shape, the base end 55 b is fitted into the hole 69. Thereby, it is possible to prevent the fitting convex portion 55 from rattling in the hole 69.

  Further, since the protrusion 69a is projected toward the back side in the thin portion 72 of the game board 30, and the hole 69 is formed through the protrusion 69a and the thin portion 72, the protrusion 69a is fitted in the hole 69. The fitting depth of the fitting convex portion 55 can be secured. As the fitting depth of the fitting projection 55 fitted in the hole 69 increases, the fitting projection 55 fitted in the hole 69 tends to be less likely to swing in the direction orthogonal to the axial direction. Since it can be seen, securing the fitting depth of the fitting convex portion 55 to be fitted in the hole 69 makes it difficult for the guide portion reinforcing member 50 fixed to the game board 30 to swing. By making it difficult to swing the guide portion reinforcing member 50 fixed to the game board 30, tilting of the outer rail portion 31 for guiding the game ball to the game area PE can be suppressed, so the game ball guided to the game area PE The trajectory and flight distance can be further stabilized.

  Further, since the projection 69a is coupled to the thin portion 72 and the hole 69 is formed to penetrate through the projection 69a and the thin portion 72, the area of the thick portion 70 is enlarged to form the hole 69. It can be unnecessary. Although the mass of the game board 30 is increased by the amount of the protrusion 69a (excluding the hole 69) coupled to the thin portion 72, it is not necessary to widen the area of the thick portion 70. The increase can be suppressed. Furthermore, since the protrusion 69a in which the hole 69 is formed penetrates and functions as a rib that enhances the rigidity of the thin portion 72 around the hole 69, the rigidity of the thin portion 72 around the hole 69 can be secured. Therefore, it is possible to implant the nail in the thick portion 70 to secure the holding power of the nail and to reduce the weight of the game board 30 while securing the rigidity of the game board 30. In addition, the trajectory and flight distance of the gaming ball guided to the gaming area PE can be further stabilized.

  Next, referring to FIG. 15, a guide reinforcing member 50 in another embodiment will be described. The same parts as those in the first embodiment are given the same reference numerals, and the description thereof will be omitted. FIG. 15 (a) is a partially enlarged rear view of the game board 30 on which the guide portion reinforcing member 80 according to the other embodiment is installed, and FIG. 15 (b) is a game on which the guide portion reinforcing member 90 according to the other embodiment is installed. FIG. In FIGS. 15 (a) and 15 (b), the fitting convex portions 85 and 95 of the guide portion reinforcing members 80 and 90 are fitted in the holes 69 formed in the game board 30 from the board surface (front side) side. And the state seen from the back side of the game board 30 is illustrated.

  The guide portion reinforcing member 80 shown in FIG. 15 (a) is a part of the outer peripheral surface along the axial direction (the direction perpendicular to the paper surface of FIG. 15 (a)) at two axially symmetrical positions of the outer peripheral surface of the fitting projection 85. Is provided with a recess 86 formed in the shape of a recess. Since the fitting convex portion 85 includes the recess 86 in which a part of the outer peripheral surface is formed in a dent shape, the outer peripheral surface of the fitting convex portion 85 when the fitting convex portion 85 is fitted in the hole 69 The contact area between the inner surface and the inner peripheral surface of the hole 69 can be reduced. As a result, it is possible to increase the vertical effectiveness per unit area of the hole 69 and the fitting convex portion 85 when the fitting convex portion 85 is fitted in the hole 69. Thus, when fitting the fitting convex portion 85 into the hole 69, the hole 69 or the fitting convex portion 85 can be easily deformed (elastically or plastically deformed). The hole 69 can be easily fitted.

  In addition, a recessed portion 85a having a circular cross section is formed substantially at the center of the fitting protrusion 85 along the axial direction of the fitting protrusion 85 from the tip of the fitting protrusion 85. By reducing the cross-sectional area of the fitting convex portion 85 by the concave portion 85a, the fitting convex portion 85 can be easily elastically deformed by the vertical force acting on the fitting convex portion 85. As a result, the fitting convex portion 85 can be further easily fitted to the hole 69, so that the workability when the fitting convex portion 85 is fitted to the hole 69 can be improved. Furthermore, by making the fitting convex portion 85 easily elastically deformable, it is possible to prevent the rattling of the fitting convex portion 85 with respect to the hole 69.

  In particular, since the recess 86 is formed in such a shape that two places are cut out along the axial direction of the fitting protrusion 85, the outer peripheral surface of the fitting protrusion 85 is prevented from becoming excessively small, A contact area with the inner peripheral surface of the hole 69 can be secured. Since the vertical effectiveness per unit area of the outer peripheral surface of the fitting convex portion 85 can be prevented from being excessive, deformation such as buckling of the outer peripheral surface of the fitting convex portion 85 can be suppressed. As a result, a gap is generated between the outer peripheral surface of the fitting convex portion 85 and the inner peripheral surface of the hole 69, and the occurrence of problems such as rattling of the fitting convex portion 85 can be suppressed.

  The guide portion reinforcing member 90 shown in FIG. 15 (b) is a part of the outer peripheral surface along the axial direction (the direction perpendicular to the paper surface of FIG. 15 (b)) at four positions in axial symmetry of the outer peripheral surface of the fitting projection 95 Is provided with a recess 96 formed in the shape of a recess. Since the fitting convex portion 95 includes the concave portion 96 in which a part of the outer peripheral surface is formed in a dent shape, the outer peripheral surface of the fitting convex portion 95 when the fitting convex portion 95 is fitted in the hole 69 The contact area between the inner surface and the inner peripheral surface of the hole 69 can be reduced. As a result, it is possible to increase the vertical effectiveness per unit area of the hole 69 and the fitting convex 95 when the fitting convex 95 is fitted in the hole 69. Thus, when fitting the fitting convex portion 95 into the hole 69, the hole 69 or the fitting convex portion 95 can be easily deformed (elastically or plastically deformed). The hole 69 can be easily fitted.

  In addition, a concave portion 95a having a circular cross section is formed at substantially the center of the fitting convex portion 95 along the axial direction of the fitting convex portion 95 from the tip of the fitting convex portion 95. By reducing the cross-sectional area of the fitting convex portion 95 by the concave portion 95 a, the fitting convex portion 95 can be easily elastically deformed by the vertical force acting on the fitting convex portion 95. As a result, the fitting convex portion 95 can be further easily fitted into the hole 69, so that the workability when the fitting convex portion 95 is fitted into the hole 69 can be improved. Furthermore, the elastic deformation of the fitting convex portion 95 makes it possible to prevent the rattling of the fitting convex portion 95 with respect to the hole 69.

  Next, a second embodiment will be described with reference to FIG. In the first embodiment, the outer peripheral edge of the opening 61 formed in the thickness direction of the game board 30 is continuous inside the outer peripheral edge of the game board 30 (the outer peripheral edge of the game board 30 is closed) The case was explained. On the other hand, in the second embodiment, the case where the opening portion 161 is formed to penetrate in the thickness direction of the gaming board 130 and a part of the outer peripheral edge of the gaming board 130 is opened will be described. The same parts as those in the first embodiment are given the same reference numerals, and the description thereof will be omitted.

In the present embodiment, a part of the outer peripheral edge of the game board 130 located on the right side in a front view is opened by the opening 161. By forming the opening 161, the game board 130 is formed to have a substantially C-shaped board surface.

  The structure 170 is connected between one predetermined portion 161 a of the periphery of the opening 161 of the game board 130 and the other predetermined portion 161 b. In the present embodiment, the structure 170 is formed in a substantially rectangular shape as viewed from the front, and connects two places of the opening 161 along the outer peripheral edge of the game board 130. In addition, the game board 130 and the structure 170 are formed of the synthetic resin which has translucency similarly to the game board 30 demonstrated in 1st Embodiment.

  A symbol display device (not shown) for variably displaying a plurality of symbols is incorporated in the main body portion 172, and a symbol display portion 173 (decorative portion) such as a liquid crystal display is disposed on the front surface of the main body portion 172 . The symbol display portion 173 is not limited to the liquid crystal display, and a CRT, a dot matrix, a 7-segment display, and other display screens can be appropriately selected.

  An insertion hole 174 into which an axial member such as a screw for fixing the structure 170 to the game board 130 is screwed is formed in the engaging portion 171.

  In the game board 130, a connecting portion (engaged portion) 131 for receiving an engaging portion 171 provided on the structure 170 is formed on a part of the periphery of the opening portion 161. The connecting portion 131 is a portion for engaging with the engaging portion 171 provided on the structure 170 to position the structure 170.

  In the present embodiment, the connecting portion 131 is provided as a step-like flat surface set one step lower than the board surface of the game board 130. The depth (lateral direction in FIG. 17) of the connecting portion 131 with respect to the board of the gaming board 130 is set to be substantially the same as the thickness (lateral direction in FIG. 17) of the engaging portion 171.

  In addition, a light scattering portion 132 is provided on the back side of the connecting portion 131. The light scattering portion 132 is a portion for scattering light emitted from the light emitting portion 181 (described later) such as an LED disposed on the back side of the game board 130 to the game board 130.

  The light emitted from the light emitting portion 181 (indicated by a two-dot chain line in FIG. 18) enters and leaves the light scattering portion 132 (engaged portion 131) due to the difference in the refractive index between air and the light scattering portion 132. When it refracts. Therefore, by causing the light emitting portion 181 to emit light, it is possible to realize lighting in a state in which light is dispersed in a large number or in a state with a three-dimensional effect. Thereby, in addition to the rendering effect by the symbol display portion 173 (decoration portion), the rendering effect by the light from the light emitting portion 181 can be improved.

  Further, by providing the light scattering portion 132 on the back side (back side) of the game board 130 (connecting portion 131), the light scattering portion 132 can be integrally formed with the game board 130 when the game board 130 is formed. As a result, the light scattering portion 132 can be easily manufactured.

  When the light scattering portion 132 is provided by processing the surface (front surface) of the game board 130 into a protrusion or a projection, the unevenness of the light scattering portion 132 interferes with the movement of the game ball, When the light scattering portion 132 is provided on the back surface (back surface) of the game board 130, it is not necessary to consider the interference of the movement of the gaming ball by the light scattering portion 132 (concave and convex). Thereby, flexibility of design of the game board 130 can be secured.

  Further, when the light scattering portion 132 is provided on the back surface side (back surface) of the game board 130 (connection portion 131), the shape of the light scattering portion 132 can be designed relatively freely. Since the outer periphery reinforcing rib 73 (see FIG. 17) standing up toward the back side is provided on the outer periphery of the game board 130, the outer periphery reinforcing rib 73 is used on the back side (back side) of the game board 130.

It can be prevented from being viewed. By scattering the light by the light scattering portion 132, it is possible to cause the light to wrap around in front of the axial member (not shown). Thus, it is possible to make it difficult to visually recognize the joint portion (connecting portion 131 and engaging portion 171) between the game board 130 and the structure 170 by the light scattered by the light scattering portion 132. It is possible to improve the rendering effect of the joint portion.

The protrusions 532a and 532b provided on the end face in the axial direction of the rail receiver 532 are disposed on the side of the board surface 530a from the board side 530a to the thickness direction of the game board 530 (FIG. 29 (a) perpendicular to the paper surface) When projected in the direction, it is provided at a position which does not interfere with the projection line of the inner rail portion 32 shown in the orthogonal plane (the plane of FIG. 29A) orthogonal to the thickness direction of the game board 530.

  The rail receiver 533 is provided in the thin portion 72 of the game board 530, and a hole 68 for mounting the outer rail portion 31 is formed to penetrate along the axial direction (vertical direction in FIG. 29A). ing. As shown in FIG. 29 (b), the rail receiver 533 has a flat-surfaced receiver 533 a formed on the end face in the axial direction. The distance from the panel surface 530a to the receiving portion 533a (the height of the rail receiver 533) is set to a value smaller than the distance from the panel surface 530a to the end face of the outer peripheral edge reinforcing rib 531 (height of the outer peripheral edge reinforcing rib 531) . Further, the height of the rail receiver 533 is set to the same value as the distance from the board surface 530 a to the receiver 532 c of the rail receiver 532 (the height of the receiver 532 c).

  The end face in the axial direction of the projecting portion 69a holding the fitting convex portion 55 of the guide portion reinforcing member 550 and the end face formed in the axial direction end face of the projecting portion 68a holding the fitting pin 31a of the outer rail portion 31 The groove 68b (see FIG. 12) also functions as a receiving portion of the rail receiving portion (a part of the rear side contact portion). The height from the board 530a is also set to the same value as the height of the receiving portion 532c.

  Next, FIG. 30 (a) is a partially enlarged rear view of the game board 530 showing a portion shown by XXXa in FIG. 26 in an enlarged manner, and FIG. 30 (b) is a game board viewed from the direction of arrow XXXb in FIG. FIG. 53 is a partial enlarged side view of 530. In FIG. 30 (a), the outer rail portion 31 disposed on the board of the game board 530 (the surface on the back side of the plane of FIG. 30 (a)) is shown by a broken line.

  As shown in FIGS. 30 (a) and 30 (b), the rail receiver 532 is provided on the inclined surface 71 of the game board 530, and the hole 68 for mounting the outer rail 31 is in the axial direction. It is penetratingly formed along (FIG. 30 (a) vertical direction in the drawing). The protrusions 532a and 532b provided on the end face in the axial direction of the rail receiver 532 are disposed on the side of the board surface 530a from the board side 530a to the thickness direction of the game board 530 (FIG. 29 (a) perpendicular to the paper surface) When projected in the direction, it is provided at a position which does not interfere with the projection line of the outer rail portion 31 shown in the orthogonal plane (the plane of FIG. 29A) orthogonal to the thickness direction of the game board 530.

  The rail receiver 534 is formed in the vicinity of a reference hole 534a (see FIG. 30) serving as a positioning reference in the manufacturing process of the game board 530 and the like, and is connected to the outer peripheral edge reinforcing rib 531. The rail receiver 534 is a portion for receiving the side edge of the outer rail portion 31 of another game board 530 when stacking a plurality of game boards 530 on which the outer rail portion 31 and the inner rail portion 32 are mounted. The rail receiver 534 has a semi-cylindrical shape, and protrudes from the back surface of the game board 530 along the thickness direction of the game board 530 (vertical direction in FIG. 30A).

  The rail receiver 534 has a flat receiving surface 534b as a surface substantially parallel to the outer peripheral reinforcing rib 531 along the thickness direction of the game board 530 (the direction perpendicular to the sheet of FIG. 30A). Is formed. At the lower end of the receiving surface 534b, a receiving portion 534c is extended toward the inside of the game board 530. The receiving portion 534c has a thickness of the game board 530 when the outer rail portion 31 disposed on the board surface 530a is projected from the board surface 530a in the thickness direction of the game board 530 (the vertical direction in FIG. 30A). It is provided so as to overlap a part of the projection line of the outer rail portion 31 shown in the orthogonal plane orthogonal to the direction (the plane of FIG. 30A).

  As shown in FIG. 30 (b), the distance from the panel surface 530a to the axial end surface of the rail receiver 534 (height of the rail receiver 534) is the distance from the panel surface 530a to the end surface of the outer peripheral edge reinforcing rib 531 (outer peripheral edge reinforcement (The height of the rib 531). Further, the distance from the board surface 530a to the receiving portion 534c (the height of the receiving portion 534c) is set to a value smaller than the height of the outer peripheral edge reinforcing rib 531. The height of the receiving portion 534c is set to the same value as the distance from the board surface 530a to the receiving portion 532c of the rail receiving portion 532 (the height of the receiving portion 532c). Since the receiving portion 534c is coupled to the upper side of the outer periphery reinforcing rib 531 of the game board 530, the stability of regulating the position when stacking the game board 530 is excellent.

  Next, FIG. 31 (a) is a partially enlarged rear view of the game board 530 showing a portion shown by XXXIa in FIG. 26 in an enlarged manner, and FIG. 31 (b) is at the line XXXIb-XXXIb in FIG. 31 (a). It is a cutting part end view. In FIG. 31 (a), the inner rail portion 32 disposed on the surface of the game board 530 (the surface on the back side of the plane of FIG. 31 (a)) is shown by a broken line.

  As shown in FIG. 31 (a), the rail receiver 532 is provided on the inclined surface 71 of the game board 530, and the hole 68 for mounting the inner rail 32 has an axial direction (FIG. 31 (a)). (Perpendicular to the paper surface). Annular reinforcing ribs 535 are erected on the back of the game board 530 around the out port 39, and holes 68 are formed on the left and right sides of the out port 39, respectively. As a result, the inner rail portion 32 can be firmly fixed to the game board 530 on both sides of the out-port 39 where game balls that can not enter the ball are provided in the game area PE.

  The inner rail portion 32 is provided with a protruding portion 32a in which the inner rail portion 32 is bent toward the outer peripheral edge side of the game board 530 at the position of the out port 39. The overhanging portion 32a is a part for facilitating the flow of the gaming ball into the out port 39, and the gaming ball which has flowed down the gaming area PE and reached the lower end of the inner rail portion 32 is outported by the overhanging portion 32a. It can flow into 39 quickly.

  The reinforcing rib 535 is provided with relief portions 535a at the left and right positions of the out port 39, and wall portions 535b are provided upright on both sides of the relief portion 535a. The relief portion 535a has a thickness of the game board 530 when the inner rail portion 32 disposed on the board surface 530a is projected from the board surface 530a in the thickness direction of the game board 530 (the vertical direction in FIG. 31A). It is provided at a position intersecting with the projection line of the inner rail portion 32 shown in the orthogonal plane orthogonal to the direction (the plane of FIG. 31 (a)). The width of the relief 535a defined by the wall 535b (the vertical direction in FIG. 31A) is set to be larger than the width of the receiving portion 532c.

  As shown in FIG. 31 (b), the relief 535 a is provided closer to the board surface 530 a than the receiving portion 532 c of the rail receiver 532. The distance from the panel surface 530a to the axial end surface of the rail receiver 532 (height of the rail receiver 532) is set to be the same as the distance from the panel surface 530a to the end surface of the reinforcing rib 535 (height of the reinforcing rib 535). Further, the distance from the board surface 530a to the relief part 535a (the height of the relief part 535a) is set to the same value as the distance from the board surface 530a to the receiving part 532c (the height of the receiving part 532c).

  Next, with reference to FIG. 32 and FIG. 33 (a), the state when the plurality of game boards 530 are stacked will be described. FIG. 32 and FIG. 33 (a) are end views of the cutting section schematically showing a state in which a plurality of gaming boards 530 are stacked. In the manufacturing process of the game board 530, first, the hole 68 for attaching the fitting pins 31a, 32a and the like and the nail (obstacle nail) 536 are inserted into the board material made of synthetic resin for the game board. A pilot hole (mounting hole) is formed. Next, a nail 536 is implanted, and a small part (not shown) such as a wind turbine, and the outer rail portion 31 and the inner rail portion 32 are attached. Next, large parts (not shown) such as a large winning device and a control circuit board are assembled. In assembling large parts, the process becomes complicated because the work becomes complicated. Due to the imbalance of the process capability, the game board 530 in the process of manufacture may temporarily stay between processes. In such a case, the game board 530 in the process of manufacture to which the nail 536, the outer rail portion 31 and the inner rail portion 32 are attached is temporarily stacked, and the stagnated game board 530 waiting for the next process is made to wait.

  In the game board 530, the height of the outer peripheral reinforcing rib 531, the heights of the rail receivers 532 and 534, and the height of the reinforcing rib 535 are set to the same value with respect to the board surface 530a. It can be placed flat on the flat surface G of the waiting place with the back side facing downward. Further, the outer peripheral reinforcing rib 531 is provided so as to protrude all around the thin portion 72, and the rail receivers 532 and 534 and the reinforcing rib 535 are dispersed around the thick portion 70 formed in a substantially circular shape. The load can be dispersed and carried on the outer peripheral reinforcing rib 531, the rail receivers 532 and 534, and the reinforcing rib 535.

  When stacking another game board 530 on the game board 530 placed flat on the flat surface G, the other side of the outer rail portion 31 and the inner rail portion 32 erected on the board surface 530 a of the game board 530 The receivers 532c, 533a, 534c of the rail receivers 532 533 534 of the game board 530 are brought into contact. Further, the side edges of the outer rail portion 31 and the inner rail portion 32 are brought into contact with the outer peripheral rail receivers 531 c and 531 d (see FIG. 33) of the other game boards 530. The belt-like outer rail portion 31 and the inner rail portion 32 are configured to have the same width, and the receiving portions 532c, 533a, 534c and the outer peripheral rail receivers 531c, 531d are set to the same height with respect to the board surface 530a. The game board 530 can be stably placed on the side edges of the outer rail portion 31 and the inner rail portion 32 via the receiving portions 532c, 533a, 534c and the outer peripheral rail receivers 531c, 531d.

  By repeating this, the game boards 530 can be stacked one after another. As a result, the outer rail portion 31 and the inner rail portion 32 receive the load of the stacked upper game board 530, so the nails 536 implanted on the board surface 530a of the game board 530 do not contact the back of the game board 530. In this case, the load on the upper game board 530 applied to the nails 536 of the stacked lower game board 530 can be made zero. In addition, even when the nail 536 implanted on the board surface 530a of the game board 530 contacts the back of the game board 530, the load of the upper game board 530 applied to the nail 536 of the stacked lower game board 530 can be It can be dispersed and made small in the receivers 532, 533, 534, the outer peripheral rail receivers 531c, 531d, the outer rail portion 31, and the inner rail portion 32. Thereby, when the game boards 530 are stacked, it is possible to prevent an adverse effect such as bending of a nail 536 implanted on the game board 530.

  The outer rail portion 31 and the inner rail portion 32 are arranged on the board surface 530a of the game board 530 by curving them in an arc shape when the board surface 530a is viewed from the front, so the thickness direction of the game board 530 (FIG. 32 vertical direction The rigidity of) can be secured. Therefore, when the load of the stacked upper game board 530 is applied to the outer rail portion 31 and the inner rail portion 32, it is possible to prevent the occurrence of a defect such as bending of the outer rail portion 31 and the inner rail portion 32. Therefore, it is possible to stack the game boards 530 without adversely affecting the nails 536, the outer rails 31, and the inner rails 32 embedded in the board 530a.

  In addition, the rail receptacles 532 533 534 (receiving parts 532 c 533 a 534 c) are formed when the plurality of game boards 530 are stacked such that the back surface of the game board 530 and the board surface 530 a of another game board 530 face each other. The height of the game board 530 in the thickness direction is set such that the nails 536 implanted on the board surface 530 a do not contact the back surface of the game board 530. As a result, the load on the upper game board 530 applied to the nails 536 of the stacked lower game board 530 can be made zero. As a result, when the gaming boards 530 are stacked, it is possible to reliably prevent an adverse effect such as bending of the nail 536 implanted on the gaming board 530.

  Further, since the rail receivers 532, 533, 534 (receivers 532c, 533a, 534c) (rear side contact portions) are provided on the back surface of the game board 530, the projection length of the nail 536 from the board surface 530a is The height of the rail portion 31 and the inner rail portion 32 can be the same or larger. In that case, when the game board 530 is attached to the main frame 3 (see FIG. 2) and the front door frame 4 is closed to constitute the pachinko machine 1, the back of the glass 14 attached to the front door frame 4 and the nail 536 The gap with the tip (end) can be reduced. Therefore, it is possible to suppress occurrence of a problem that the gaming ball is caught between the back surface of the glass 14 and the tip of the nail 536 during the game.

  In the rail receivers 532 and 534, receiving surfaces 532a1, 532b1 and 534b along side surfaces in the longitudinal direction of the outer rail portion 31 and the inner rail portion 32 project from the receiving portions 532c and 534c in the thickness direction of the game board 530 It is done. Thus, when the positions of the stacked game boards 530 are shifted in the direction orthogonal to the longitudinal direction of the outer rail portion 31 and the inner rail portion 32, the receiving surfaces 532a1, 532b1, 534b form the outer rail portion 31 and the inner rail portion 32. At the end, further positional deviation of the game board 530 is prevented. As a result, the state in which the side edges of the outer rail portion 31 and the inner rail portion 32 abut on the receiving portions 532 c and 534 c can be maintained, so that sliding of the stacked upper game boards 530 can be suppressed.

  Further, in the outer rail portion 31 and the inner rail portion 32, fitting pins 31a and 32a are provided protruding outward in the width direction of the outer rail portion 31 and the inner rail portion 32 from their side edges. On the other hand, the game board 530 is formed with a hole 68 into which the fitting pins 31a and 32a are fitted, and the fitting pin 31a and 32a is fitted into the hole 68, whereby the outer rail 31 and the inside of the game board 530 are formed. The rail portion 32 is attached. Since the holes 68 are formed at the positions of the rail receivers 532 533, the depth of the holes 68 can be secured by the height of the rail receivers 532 533 in the thickness direction of the game board 530. Thus, the holding force of the fitting pins 31a and 32a inserted into the hole 68 can be increased. Therefore, the outer rails 31 and the inner rails 32 can be firmly fixed to the game board 530 by firmly fixing the fitting pins 31 a and 32 a to the game board 530.

  Further, since the relief portions 535a wider than the receiving portion 532c are formed on the left and right of the reinforcing rib 535 (see FIG. 31A), the protruding portions 32a formed in the inner rail portion 32 are stacked. Interference with the reinforcing rib 535 of the game board 530 can be prevented. Further, the clearances 535a (see FIG. 31 (b)) have the height from the board surface 530a set lower than the receiving portions 532c, so the height of the protruding portions 32a (the vertical direction in FIG. 31 (a)). Can be prevented from interfering with the relief portion 535a of the stacked game board 530 even when the value is set to a value larger than the height of the inner rail portion 32. This makes it possible to prevent the bending portion 32a from producing an adverse effect such as plastic deformation of the overhanging portion 32a and a change in shape while the plurality of game boards 530 are stacked and waiting.

  Further, since the height of the outer peripheral rail receivers 531 c and 531 d in the thickness direction of the game board 530 is set to a value smaller than that of the outer peripheral reinforcing rib 531, the outer peripheral reinforcing rib 531 is formed on the flat surface G. When the game board 530 is placed downward, a gap is created between the flat surface G and the game board 530 by the amount of the outer peripheral rail receivers 531 c and 531 d. A fingertip or the like of a hand can be inserted into the gap, and the gaming board 530 placed on the flat surface G can be lifted using the inserted fingertip or the like as a clue.

  On the other hand, when the heights of the outer peripheral rail receivers 531 c and 531 d in the thickness direction of the game board 530 are set to a value larger than the height of the outer peripheral reinforcing rib 531, A rattling occurs on the set game board 530. The game board 530 can solve this problem, and the outer peripheral reinforcing rib 531 faces downward, and the play of the game board 530 placed flat on the flat surface G can be prevented, and the game board can be stably set. Furthermore, when lifting the game board 530 placed flat, it is possible to use the fingertips inserted in the outer peripheral rail receivers 531 c and 531 d as a clue, and the handling of the game board 530 in the middle of manufacturing and the completed game board 530 It can improve.

  Further, the heights of the outer peripheral rail receivers 531 c and 531 d in the thickness direction of the game board 530 are set to the same values as the rail receivers 532, 533 and 534 (receivers 532 c, 533 a and 534 c), When a plurality of game boards are stacked so that the back surface of the game board 530 and the board surface 530a of another game board 530 face each other, the board surfaces 530a of the plurality of game boards 530 can be substantially parallel. As a result, the plurality of game boards 530 can be stacked substantially vertically, and it is possible to make it difficult for the stacked game boards 530 to slide down. Furthermore, the outer rail portion 31 of the game board 530 is prevented from interfering with the outer peripheral rail receivers 531 c and 531 d of the stacked game board 530. As a result, it is possible to prevent an adverse effect such as deformation of the outer rail portion 31 while the plurality of game boards 530 are stacked and waiting.

  In addition, when a plurality of game boards 530 are stacked, the outer rail portion 31 is provided with a projection (rail receiver) 69a provided on another game board 530, a rail receiver 533 (provided upright on the thin portion 72), a rail It abuts on the receivers 532 and 534 and the outer peripheral rail receivers 531 c and 531 d. On the other hand, the inner rail portion 32 abuts on a rail receiver 532 (provided erect on the inclined surface portion 71) provided on another game board 530.

  Here, the gaming balls fired from the gaming ball launching device 21 move along the outer rail portion 31 by centrifugal force and are guided to the gaming area PE. Therefore, the curvature or the like of the outer rail portion 31 affects the trajectory of the game ball driven into the game area PE. On the other hand, since the inner rail portion 32 is disposed on the inner side of the outer rail portion 31, the influence of the curvature or the like of the inner rail portion 32 on the trajectory of the gaming ball is smaller than that of the outer rail portion 31. When the game boards 530 are stacked, the game board 530 is supported by the rail receivers 532 and the like coming into contact with the inner rail portion 32 and the outer rails 31, so the load of the stacked game boards 530 is the outer rail portion 31. Concentrated loads are prevented. That is, by dispersing the load applied to the outer rail portion 31 to the inner rail portion 32, the load applied to the outer rail portion 31 can be reduced. Thus, plastic deformation of the outer rail portion 31 can be prevented by stacking the game boards 530. Thus, the trajectory of the game ball driven into the game area PE can be stabilized.

  Further, the contact area between each of the rail receivers 534 and the outer peripheral rail receivers 531 c and 531 d and the outer rail portion 31 is larger than the contact area between each of the rail receivers 532 and 533 and the inner rail portion 32. Therefore, the load per unit area applied to the outer rail portion 31 can be reduced by the rail receivers 534 and the outer peripheral rail receivers 531 c and 531 d. As a result, plastic deformation of the outer rail portion 31 due to the load of the stacked game boards 530 can be suppressed.

  Here, in the outer rail portion 31, the portion facing the inner rail portion 32 (left side in FIG. 24) has a great influence on the trajectory of the game ball hit from the game ball launch device 21 into the game area PE. This is because the gaming ball moves along the outer rail portion 31 opposed to the inner rail portion 32 by centrifugal force. On the other hand, the area U (see FIG. 24) of the outer rail portion 31 located to the right of the reference hole 534a when the gaming board 530 is viewed from the front has a relatively small influence on the trajectory of the gaming ball driven into the gaming area PE. . This is because the trajectory of the gaming ball moving along the area U is restricted not only by the outer rail portion 31 but also by the shape and arrangement of the surface components such as the center frame 47 and the like.

  Therefore, when stacking the plurality of game boards 530, the heights of the rail receivers 532 and 534 are such that the rail receivers 532 and 534 located in the area U of the outer rail unit 31 and in the vicinity thereof abut the outer rail unit 31. It is effective to set Even if the outer rail portion 31 (area U) is plastically deformed by the load of the stacked game board 530, it has little influence on the trajectory of the game ball.

  In this case, in the outer rail portion 31, only the area U is in contact with the rail receiver 532 of the other game board 530, and the region other than the area U is noncontact with the rail receiver 532 of the other game board 530 or the like. The height of the receiver 532 is set. The inner rail portion 32 sets the height of the rail receiver 532 or the like so as to abut on the rail receiver 532 or the like of another game board 530. As a result, when the area U of the outer rail portion 31 and the inner rail portion 32 abut on the rail receivers 532 and the like of the other game boards 530, the plurality of game boards 530 are stacked. Thereby, in the outer rail portion 31, the load of the stacked game board 530 is applied to a part (a part other than the area U) which greatly affects the trajectory of the game ball hit from the game ball launch device 21 to the game area PE. Can be prevented. As a result, it is possible to prevent a portion (a portion other than the area U) which greatly affects the trajectory of the gaming ball driven into the game area PE from being adversely affected by the load of the stacked game boards 530.

  Also, in addition to the rail receptacles 532 disposed in the area U of the outer rail portion 31, a rail receptacle 534 (see FIG. 26) disposed in the vicinity of the area U of the outer rail portion 31 is used. It is possible to support the outer rail portion 31. The rail receiver 534 is provided in the reference hole 534a, and the area of the receiver 534c (FIG. 30) can be secured. Therefore, when supporting the outer rail portion 31, compared to the case where the rail receiver 534 is not used. Thus, the load acting on the unit area of the outer rail portion 31 can be reduced. Thereby, compared with the case where the rail receptacle 534 is not used, it can be hard to have a bad influence on the area | region U of the outer rail part 31 by the load of the accumulated game board 530. FIG.

  In the present embodiment, the area U of the outer rail portion 31 abuts the rail receiver 532 of the other game board 530, and the portion (outer rail portion 31) other than the area U is the rail receiver 532 of the other game board 530. Although the case of setting the height of the rail receiver 532 or the like to be noncontact with the etc. has been described, the area U of the outer rail portion 31 is also noncontact with the rail receiver 532 of another game board 530 It is of course possible to set the height of the receptacle 532. Thus, the load of the stacked game boards 530 can be prevented from being applied to the outer rail portion 31, and thus the outer rail portion 31 can be prevented from being adversely affected by the load of the stacked game boards 530. Since the game board 530 is supported by the inner rail portion 32 and the rail receiver 532 which hardly affect the trajectory of the game ball, the trajectory of the game ball can be stabilized even if the inner rail portion 32 is plastically deformed. .

  Next, another embodiment is described with reference to FIG. In the sixth embodiment, the case where the game board 530 is placed on the outer rail portion 31 and the inner rail portion 32 by the outer peripheral rail receiver 531 d and the rail receiver 532 has been described. On the other hand, in another embodiment shown in FIG. 33 (b), the case where the game board 560 is placed on the outer rail portion 31 and the passage forming member 538 by the outer peripheral rail receivers 531d and 531f will be described. The same parts as those described in the sixth embodiment are assigned the same reference numerals and explanation thereof will be omitted. FIG. 33 (b) is a cutting section end view schematically showing a state in which a plurality of gaming boards 560 in another embodiment are stacked.

  As shown in FIG. 33 (b), in the state where the gaming board 560 is mounted on the pachinko machine 1 (see FIG. 2), the outer rail portion 31 protrudes on the left outer edge when the gaming board 560 is viewed from the front. The passage forming member 538 (a kind of rail member) is disposed in the vicinity of the outer peripheral edge on the right side of the board. The passage forming member 538 is a member made of a synthetic resin continuously connected to the inner rail portion 32 to partition the game area PE, and is fixed on the right side of the board of the game board 560 with a screw or the like. The height from the surface of the passage forming member 538 is set to be substantially the same as the height from the surface of the outer rail portion 31 and the inner rail portion 32.

  The outer peripheral edge reinforcing rib 531 (right side when viewed from the game board 560) located at a position facing the outer peripheral edge reinforcing rib 531 (left from the front view of the game board 560) where the outer edge rail receiver 531d is formed is An outer peripheral rail receiver 531 f is formed on the rear end surface. The outer peripheral rail receiver 531 f is a portion for receiving the passage forming member 538 fixed to the other game board 560 when the plurality of game boards 560 are stacked, and the height from the board is the outer peripheral rail It is set to the same value as the receiving 531 d.

  The game board 560 has a hole 68 which is formed to penetrate in the thickness direction, and a protrusion 537 is provided around the hole 68. The axial length (the vertical direction in FIG. 33B) of the protrusion 537 is set to a value shorter than the axial length of the rail receiver 532 (see FIG. 33A). Therefore, when the plurality of game boards 530 are stacked, the side edge (upper end) of the inner rail portion 32 provided on the game board 560 and the projecting part 537 are in a non-contact state. Therefore, the game board 560 is placed and stacked on the outer rail portion 31 and the passage forming member 538 by the outer peripheral rail receivers 531 d and 531 f. Since the outer peripheral rail receivers 531 d and 531 f are provided on the outer peripheral reinforcing rib 531, even if the outer rail portion 31 and the passage forming member 538 are arranged so as to project over the outer peripheral edge of the game board 560, the game board 560 Can be prevented from interfering with the outer rail portion 31 and the passage forming member 538 and the outer peripheral reinforcing rib 531. Thereby, the game area PE of the game board 560 can be greatly expanded.

  Referring now to FIG. 34, another embodiment of the rail receptacle 532 will be described. In the sixth embodiment, the case where the protrusions 532a and 532b, which are opposed to each other, project from the receiving portion 532c formed on the axial end surface of the rail receiver 532 has been described. On the other hand, in FIG. 34, the case where one of the protrusions 532a and 532b is provided in the receiving portion 532c will be described. The same parts as those in the sixth embodiment are given the same reference numerals, and the description thereof will be omitted. FIGS. 34 (a) and 34 (b) are cutting end views schematically showing a state in which a plurality of gaming boards 570, 580 according to another embodiment are stacked.

  As shown in FIG. 34 (a), each rail receiver 542 is provided with a protrusion 532b located on the thick portion 70 side (the center side of the game board). Since the projection 532b (the receiving surface 532b1) faces the outer rail portion 31 and the inner rail portion 32, positional deviation of the stacked game boards 570 can be prevented, and sliding of the game boards 570 can be prevented.

  Further, as shown in FIG. 34 (b), each rail receiver 543 is provided with a protrusion 532a located on the outer peripheral edge reinforcing rib 531 side (the outer peripheral side of the game board). Since the projection 532a (the receiving surface 532a1) faces the outer rail portion 31 and the inner rail portion 32, positional deviation of the stacked game boards 580 can be prevented, and sliding of the game boards 580 can be prevented.

  Next, referring to FIG. 35 and FIG. 36, the guide portion reinforcing member 550 fixed to the board surface 530a of the game board 530 will be described. The guide portion reinforcing member 550 is a member for reinforcing the outer rail portion 31. In the first embodiment, the inclined portion 52a coupled to the contact portion 52b of the guide portion reinforcing member 50 is formed to have substantially the same width with respect to the distance separating from the fitting convex portion 55 when viewed from the front. Case was explained. On the other hand, in the present embodiment, the case where the inclined portion 553 is formed so as to increase in width in a front view as being away from the fitting convex portion 55 will be described. The same parts as those described in the first embodiment are given the same reference numerals, and the description thereof will be omitted. FIG. 35 (a) is a partially enlarged front view of the game board 530 to which the guide portion (outer rail portion 31) and the guide portion reinforcing member 550 are fixed, and FIG. 35 (b) is a line XXXVb-XXXVb in FIG. FIG. 16 is an end view of the guide (the outer rail 31) and the cut portion of the guide reinforcing member 550 in FIG.

  As shown in FIGS. 35 (a) and 35 (b), the guide portion reinforcing member 550 is formed into a substantially trapezoidal shape in a front view (as viewed from the board side of the game board 530) and the outer rail portion 31. Body 51 located on the opposite surface side of the guide surface 31c, the opposite surface side projecting portion 551 erected on the substrate portion 51, and the direction opposite to the direction in which the opposite surface side projecting portion 551 is erected It is mainly provided with the fitting convex part 55 protrudingly provided from the base | substrate part 51 in direction. The guide portion reinforcing member 550 is a member made of synthetic resin.

  The opposite surface side projecting portion 551 is connected to a contact portion 552 which contacts at least a part of the opposite surface of the outer rail portion 31 while facing the opposite surface of the outer rail portion 31, and the contact portion 552 And an inclined portion 553 which is inclined downward toward the axial direction of the fitting protrusion 55 from the top. The inclined portion 553 is provided so as to be offset with respect to the fitting convex portion 55 radially outward with the fitting convex portion 55 as a rotation center. Furthermore, the inclined portion 553 is formed such that the distance from the contact portion 552 increases in a front view as the distance from the fitting convex portion 55 increases. In other words, the sloped portion 553 is formed such that the width in the front view increases as the distance from the fitting convex portion 55 increases.

  Next, with reference to FIG. 36, a method of attaching the guide portion reinforcing member 550 and the outer rail portion 31 to the game board 530 will be described. FIG. 36 (a) is a partially enlarged front view of the game board 530 showing a state in which the guide portion reinforcing member 550 is fixed, and FIG. 36 (b) is a portion in which the guide portion (outer rail portion 31) and the guide portion reinforcing member 550 are fixed. 3 is a partially enlarged front view of the game board 530 showing a state of playing. In FIG. 36 (a), the position of the outer rail portion 31 disposed on the game board 530 is shown by a two-dot chain line.

  As shown in FIG. 36 (a), in the case where the guide portion reinforcing member 550 and the outer rail portion 31 are disposed on the board surface 530a of the game board 530, the fitting convex portion 55 of the guide portion reinforcing member 550 is A half of the length is inserted into the hole 69 of the disc 530 and temporarily arranged. At the time of temporary arrangement, the position of the inclined portion 553 is made to overlap the position (two-dot chain line) where the outer rail portion 31 is arranged in a front view.

  Next, as shown in FIG. 36 (b), in order to dispose the outer rail portion 31, the side edge of the outer rail portion 31 (the rear side edge in the paper surface of FIG. 36 (b)) Get closer. Since the inclined portion 553 is provided so as to be offset radially outward with respect to the fitting convex portion 55 which is the rotation center with respect to the hole 69, as the outer rail portion 31 approaches the board surface 530a, The inclined portion 553 is pushed by the outer rail portion 31, and the guide portion reinforcing member 550 rotates around the fitting convex portion 55. When the side edge of the outer rail portion 31 (the back side edge in FIG. 36B) leaves the inclined portion 553, the pivoting of the guide portion reinforcing member 550 is stopped and the position of the guide portion reinforcing member 550 is determined.

  Furthermore, when the outer rail portion 31 is brought close to the board surface 530a, the outer rail portion 31 is accommodated in the groove portion 58 between the contact portion 552 and the guide surface side protruding portion 57. When the outer rail portion 31 is further brought close to the board surface 530a in that state, the base end side end face (bottom surface of the groove portion 58) of the fitting convex portion 55 is pushed to the side edge of the outer rail portion 31. The holes 69 are gradually inserted. Thereby, the workability of the arrangement operation of arranging the outer rail portion 31 to the board surface 530 a of the game board 530 can be improved.

  As described above, the inclined portion 553 provided to be offset radially outward with respect to the fitting convex portion 55 serving as the center of rotation causes the force to cause the outer rail portion 31 to approach the board surface 530a. It can be converted to a force for pivoting the guide portion reinforcing member 550 around 55. As a result, before the outer rail portion 31 is disposed, in the work of inserting the fitting convex portion 55 of the guide portion reinforcing member 550 into the hole portion 69 of the game board 530 and temporarily arranging, the position of the inclined portion 553 is the outer rail It may be made to overlap with the position where the portion 31 is disposed. Therefore, it is possible to hardly require the accuracy of the position alignment (angle alignment of the contact portion 552 with the fitting convex portion 55 which is the rotation center) in the temporarily arranging operation. As a result, the outer rail portion 31 and the guide portion reinforcing member 550 can be smoothly arranged on the board surface 530a of the game board 530, and the workability of the arranging operation can be improved.

  Further, the inclined portion 553 is formed such that the distance from the contact portion 552 increases in a front view as the distance from the fitting convex portion 55 increases. That is, in the front view, the sloped portion 553 is formed to have a narrow width on the side of the fitting convex portion 55, and is formed so as to widen as it is separated from the fitting convex portion 55. Thereby, the position alignment in the operation of temporarily arranging the guide portion reinforcing member 550 on the game board 530 by an amount that can increase the width of the inclined portion 553 on the opposite side to the fitting convex portion 55 The accuracy of the angular alignment of the contact portion 552 with respect to 55 can be reduced. As a result, the time required for alignment of the operation of temporarily arranging the guide portion reinforcing member 550 on the game board 530 can be shortened, and the operation of arranging the outer rail portion 31 and the guide portion reinforcing member 550 can be streamlined.

The holding power of the nail implanted in the part 70 can be secured.

  In addition, since the thickness of the thick portion 70 of the gaming board 30 is set smaller than the height of the outer peripheral reinforcing rib 73, the game of uniform thickness in which the height of the outer peripheral reinforcing rib 73 is the plate thickness It can be lightweight compared to the board. A space can be provided on the back side of the thick portion 70 by the setting of the plate thickness of the thick portion 70 to be smaller than the height of the outer peripheral reinforcing rib 73. Therefore, ornaments and the like are arranged in the space on the back side. It is possible to Since it is also possible to dispose a light emitting element such as an LED in the space on the back side, the rendering effect can be improved.

  Furthermore, since the thin portion 72 having a smaller plate thickness than the thick portion 70 is formed between the thick portion 70 and the outer peripheral reinforcing rib 73, the plate thickness of the thick portion 70 and the plate thickness of the thin portion 72 The amount of synthetic resin can be reduced by the difference between Thereby, the game board 30 can be further reduced in weight. In addition, since a space can be provided on the back side of the thin portion 72 by an amount corresponding to the thickness of the thin portion 72 set smaller than the height of the outer peripheral reinforcing rib 73, a decoration or the like is disposed in the space on the back side. It becomes possible. Since it is also possible to dispose a light emitting element such as an LED in the space on the back side, the rendering effect can be improved.

  Further, since the outer peripheral edge reinforcing rib 73 is erected on the outer peripheral edge of the thin portion 72, the rigidity of the thin portion 72 can be improved, and deformation such as warpage of the thick portion 70 and the thin portion 72 can be prevented. Thereby, the flatness of the board of the game board 30 can be secured.

  An inclined surface portion 71 is formed on the outer periphery of the thick portion 70. The inclined surface portion 71 is set to be gradually smaller in thickness as it goes from the thick portion 70 to the outside, and is connected to the thin portion 72. Thereby, it is possible to suppress the occurrence of deformation due to the difference in thickness between the thick portion 70 and the thin portion 72 when the game board 30 is formed. That is, the game board 30 is molded by melting and filling a synthetic resin in a cavity of a molding die, and after curing, the molded body is taken out from the molding die. Since the cooling rate of the molded body is faster in the thinner portion 72 with a smaller thickness than in the thick portion 70 with a larger thickness, residual stress occurs due to the difference in the cooling rate, and deformation such as warpage is likely to occur in the game board 30 However, the inclined surface portion 71 coupled between the thin portion 72 and the thick portion 70 can buffer the occurrence of residual stress due to the difference in cooling rate. As a result, it is possible to make it difficult for the gaming board 30 to be deformed such as warp.

  The hole 68 formed at the boundary between the thick portion 70 and the inclined surface 71 is a portion into which a fitting pin (described later) spot-welded to the inner rail 32 is inserted. The hole 68 which is located on the outer peripheral side of the game board 30 from the boundary between the thick portion 70 and the inclined surface 71 and formed in the thin portion 72 and the peripheral portion reinforcing rib 73 is spot-welded to the outer rail portion 31. It is a part where a mating pin (described later) is inserted. In the hole 68, a cylindrical protrusion 68a standing from the periphery of the hole 68 toward the rear surface side is provided in a row. The hole 68 penetrates the game board 30 in the thickness direction.

  Since the protrusion 68 a is formed around the hole 68, the plate thickness around the hole 68 can be increased. As a result, since the load per unit area applied by the fitting pin to the inner periphery of the hole 68 can be reduced, it is possible to prevent cracks from occurring around the hole 68 (particularly, the thin portion 72). Further, since the depth of the hole 68 (the front-rear direction of the game board 30) can be increased by the protrusion 68a, the holding force of the fitting pin can be increased. Thereby, the outer rail portion 31 and the inner rail portion 32 can be firmly fixed to the board of the game board 30.

  Further, a protrusion 68a (hole 68) into which the fitting pin spot-welded to the inner rail 32 is inserted is formed at the boundary between the thick portion 70 and the inclined surface 71, and the thickness of the protrusion 68a is increased. The portion 70 and the inclined surface portion 71 are provided in series. Since the plate thickness of the thick portion 70 and the inclined surface portion 71 is larger than the plate thickness of the thin portion 72, the projection length of the projection 68 a with respect to the thick portion 70 and the inclined surface portion 71 is greater than the projection length of the projection 68 a with respect to the thin portion 72 It can be made smaller. As a result, the bending moment of the projecting portion 68 a with respect to the thick portion 70 and the inclined surface portion 71 can be made smaller than the bending moment of the projecting portion 68 a with respect to the thin portion 72. The bending strength of 68 a can be improved more than the bending strength of the protrusion 68 a provided in the thin portion 72.

  In addition, a fitting pin spot-welded to the inner rail portion 32 is inserted into the hole 68 formed in the projecting portion 68 a formed at the boundary between the thick portion 70 and the inclined surface 71. By providing the thick portion 70 on the inner side of the inner rail portion 32 in which the game area PE is formed, the holding power of nails, a windmill, etc. can be secured. The area of the thick portion 70 is excessive by providing a projection 68a (hole 68) into which the fitting pin spot-welded to the inner rail 32 is inserted at the boundary between the thick portion 70 and the inclined surface 71. Can be prevented from increasing. By not enlarging the thick portion 70 outside the area (inside the inner rail portion 32) where the game area PE is formed, the amount of synthetic resin forming the game board 30 is reduced, and the mass of the game board 30 is increased. It can be prevented from becoming larger than necessary.

  The out port 39 is formed at the boundary between the thick portion 70 and the inclined surface portion 71 at the lower position of the gaming board 30 and penetrates in the thickness direction of the gaming board 30. A reinforcing rib 39a is erected toward the back side around the out port 39, and the reinforcing rib 39a is integrally formed with the game board 30. The reinforcing rib 39a forms a passage for gaming balls having entered the out slot 39 from the gaming area PE, and can reinforce the periphery of the out slot 39 to improve rigidity.

  The hole 69 is a portion into which the fitting convex portion 55 (to be described later) of the guide portion reinforcing member 50 is inserted and is formed to penetrate the thin portion 72. Since the protrusion 69 a is formed around the hole 69, the plate thickness around the hole 69 can be increased. As a result, the load per unit area applied by the fitting convex portion to the inner periphery of the hole 69 can be reduced, so that it is possible to prevent the occurrence of cracks around the hole 69 (thin portion 72). Further, since the depth of the hole 69 (the front-rear direction of the game board 30) can be increased by the projection 69a, the holding power of the fitting projection 55 can be increased. Thus, the guide portion reinforcing member 50 can be firmly fixed to the board of the game board 30.

  In the outer peripheral edge reinforcing rib 73, recessed portions 73a, 73b, 73c are formed in which a part of the end face on the back side (the front side in FIG. 7) is recessed in the height direction (the height of the rib is lowered). . Recesses 73a and 73c are formed at opposite positions of outer peripheral edge reinforcing ribs 73 (left and right ribs), and recessed portion 73b intersects outer peripheral edge reinforcing ribs 73 (left and right ribs) in which recessed portions 73a and 73c are formed. It is formed in the outer periphery reinforcing rib 73 (lower rib). Since the recessed portions 73a and 73c are formed at the opposing positions of the outer peripheral reinforcing ribs 73, the outer peripheral reinforcing ribs 73 are directed downward onto the table having the flat surface formed on the upper surface thereof. In the case where the rear surface is turned downward, a gap is formed between the flat surface and the game board 30 (the outer peripheral edge reinforcing rib 73) by the amount of the recessed portions 73a and 73c. A fingertip or the like of a hand can be inserted into the gap, and the gaming board 30 placed on the flat surface can be lifted using the inserted fingertip or the like as a clue.

  On the other hand, when the recessed portions 73a, 73b and 73c are not formed on the end face of the outer peripheral surface reinforcing rib 73 on the back surface side, the outer peripheral reinforcing rib 73 is lowered on a table having a flat surface on the upper surface. When the game board 30 is placed facing the rear side (the rear side faces down), the entire circumference of the rear side end face of the outer peripheral reinforcing rib 73 is in close contact with the flat surface (no gap is formed). In that case, since it is difficult to insert a fingertip or the like between the outer peripheral reinforcing rib 73 and the flat surface (base), there arises a problem that it is difficult to lift the game board 30. According to the present embodiment, this problem can be solved by forming the recessed portions 73 a, 73 b and 73 c in the outer peripheral edge reinforcing rib 73.

  The openings 62 are through holes to which the projecting pins 60 are attached, and are formed at two diagonal positions of the game board 30. A reinforcing rib 62a is erected toward the back side around the opening 62, and the reinforcing rib 62a is connected to the outer peripheral wall reinforcing rib 62a.

  The heights of the reinforcing ribs 39a and 62a and the protrusions 68a and 69a are set to be substantially the same as the height of the peripheral edge reinforcing rib 73. Thus, with the gaming board 30 being placed with the outer peripheral reinforcing rib 73 facing downward (the back side facing down) on the table having the flat surface formed on the upper surface, When a load is applied to the front surface, the load can be received by the reinforcing ribs 39a and 62a, the protrusions 68a and 69a, and the peripheral edge reinforcing rib 73.

  On the other hand, when the reinforcing ribs 39a and 62a and the projecting portions 68a and 69a are not formed, when the game board 30 receives a load from the board surface, bending deformation occurs in the thick portion 70 and the thin portion 72. When the deformation is large, the vicinity of the boundary between the peripheral portion reinforcing rib 73 and the thin portion 72 may be broken. According to the present embodiment, by setting the heights of the reinforcing ribs 39a and 62a and the projecting portions 68a and 69a to be substantially the same as the height of the peripheral portion reinforcing rib 73, the thick portion 70 and the thin portion can be thin Since the occurrence of bending deformation in the portion 72 can be suppressed, this problem can be solved.

  In particular, since the protrusions 68a for fixing the outer rail portion 31 and the inner rail portion 32 are located on a substantially semicircular line and widely dispersed on the game board 30, a specific location on the board of the game board 30 Even when the concentrated load is applied to the game board, it is possible to prevent the occurrence of a large bending deformation on the board of the game board 30. This makes it possible to prevent the game board 30 from being damaged by the load applied to the game board 30 when a nail is planted on the game board 30 or various game components are attached.

  The opening 62 and the projecting pin 60 will now be described with reference to FIG. FIG. 9 is an end view of the cutting portion of the game board 30 taken along line IX-IX in FIG. As shown in FIG. 9, the projecting pin 60 is a substantially cylindrical member formed of a separate member from the gaming board 30, and includes a collar 60a projecting in the radial direction (the left and right direction in FIG. 9) from the outer peripheral surface. A fitting and inserting portion 60b extending from the collar portion 60a to the other side in the axial direction is provided in a row. The insertion portion 60b is a portion to be inserted into the opening 62, and the collar portion 60a is a portion for regulating the insertion depth of the insertion portion 60b to be inserted into the opening 62. On the other hand, on the surface of the game board 30, a recessed portion 62b for receiving the hook 60a is formed. The recessed portion 62 b is continuously provided around the opening 62 at a depth substantially the same as the thickness of the flange portion 60 a. The diameter of the protruding pin 60 is slightly smaller than the diameter of the insertion portion 60b (the inner diameter of the opening 62).

  The end face of the reinforcing rib 62a on the back side (the lower side in FIG. 9) is set at the same height position as the end face on the back side (the lower side in FIG. 9) of the peripheral edge reinforcing rib 73. Thus, the depth (vertical direction in FIG. 9) of the opening 62 can be increased, so that the insertion depth of the insertion portion 60b inserted into the opening 62 can be increased. On the other hand, when the reinforcing rib 62 a is not formed, the depth of the opening 62 is the same as the thickness of the thin portion 72. In that case, compared with the present embodiment, the holding force for holding the insertion portion 60b in the opening 62 becomes smaller, and the protrusion pin 60 is easily rattled or detached. By providing the reinforcing rib 62a as in the present embodiment, this can be prevented.

  In addition, since the gaming board 30 in which the fitting and inserting portion 60b is inserted into the opening 62 has the hook portion 60a, the projecting pin 60 protrudes from the face of the gaming board 30 by a predetermined length. On the other hand, the reinforcing rib 62a is set on the back surface side (the lower side in FIG. 9) so as to form a depression (hole) deeper than the projection length of the projecting pin 60 from the plate surface. The diameter of the projecting pin 60 is formed slightly smaller than the diameter of the insertion portion 60b (the inner diameter of the opening 62), so when a plurality of gaming boards 30 are stacked, from the board surface of one gaming board 30 The protruding protruding pin 60 is inserted into the recess (hole) in the reinforcing rib 62 a from the back side of the other gaming board 30. As a result, it is possible to prevent the positional deviation of the game board 30 stacked in the flat state in the direction of the board surface.

  In addition, by forming the projecting pin 60 as a separate member from the gaming board 30 as in the present embodiment, after the gaming board 30 is formed, the gaming board is engaged until the projecting pin 60 is fitted to the opening 62. The projecting pins 60 can be made not to protrude from the plate surface 30. As a result, after the game board 30 is formed, the projection pins 60 prevent the transportation of the game board 30 from being interrupted or the projection pins 60 are broken until the projection pins 60 are fitted into the opening 62. it can. Further, after the projecting pin 60 is fitted to the opening 62, if the projecting pin 60 is not necessary when assembling the pachinko machine 1 or the like, the projecting pin 60 can be removed from the opening 62. Thereby, assembly etc. of the pachinko machine 1 can be performed smoothly.

  In addition, it is possible to form the projecting pins 60 integrally with the gaming board 30 when the gaming board 30 is formed. When the projecting pin 60 is fitted (inserted) into the game board 30 as in the present embodiment, it is necessary to prepare the projecting pin 60 as a separate member and insert the projecting pin 60 into the game board 30. On the other hand, by forming the projecting pin integrally with the game board, it is not necessary to prepare the projecting pin 60 as a separate member, so that the number of parts can be reduced. Further, the work of inserting the projecting pin 60 into the game board 30 can be made unnecessary.

  FIG. 10 is a schematic view showing a state in which a plurality of game boards 30 are stacked. The game board 30 is integrally molded by melting and filling a synthetic resin in a molding die, and an outer peripheral edge reinforcing rib 73 is provided upright on the back side of a flat board surface (front side). When the game boards 30 made of synthetic resin are stacked and transported, there is a problem that the position is shifted and it is easy to slide off as compared with the case where the conventional game boards made of wooden plywood are stacked and transported. The game board 30 made of synthetic resin is slippery because the surface smoothness of the board is high and the coefficient of friction is small as compared with the game board made of wooden plywood.

  On the other hand, according to the present embodiment, the game board 30 is stacked by inserting the projecting pin 60 of one game board 30 into a recess (hole) in the reinforcing rib 62 a of the other game board 30. It can be easily transported. In addition, since it is easy to insert a fingertip or the like into the gap formed by the recess 73a formed on the end face of the outer peripheral reinforcing rib 73, the game board 30 can be easily lifted. Further, since the recessed portions 73a and 73c are formed at the opposing positions of the outer peripheral edge reinforcing rib 73, it is possible to lift in a well-balanced manner by inserting the fingertips or the like of the hand from the left and right into the recessed portions 73a and 73c. Furthermore, since the recessed portion 73b is formed in the outer peripheral edge reinforcing rib 73 (located below FIG. 7) intersecting the outer peripheral edge reinforcing rib 73 (located at the right and left in FIG. 7) where the recessed portions 73a and 73c are formed. The game board 30 can be supported from three sides of the game board 30, and the game board 30 can be transported in a well-balanced manner.

  Next, the guide portion reinforcing member 50 will be described with reference to FIGS. 11 to 14. 11 is a partially enlarged front view of the game board 30 to which the guide portion (outer rail portion 31) and the guide portion reinforcing member 50 are fixed, FIG. 12 is a partially enlarged rear view thereof, and FIG. FIG. The guide portion reinforcing member 50 is a member for preventing the outer rail portion 31 on which the game ball launched from the game ball launch device 21 first collides from swinging. By the guide portion reinforcing member 50 being applied to the outer rail portion 31, swinging of the outer rail portion 31 is prevented. As a result, the trajectory of the game ball and the flight distance of the game ball to the game area PE can be stabilized.

  First, the outer rail portion 31 will be described with reference to FIG. The outer rail portion 31 is formed of a band-shaped thin plate made of metal (stainless steel), and fitting pins 31a are spot-welded at side edges in the longitudinal direction of the outer rail portion 31 with an appropriate interval. The outer rails 31 are erected on the game board 30 by inserting the fitting pins 31 a into the holes 68 formed in the game board 30.

  Further, the outer rail portion 31 is provided with a bent portion 31 b which is bent in a longitudinal end edge and turned back into a substantially U shape. The bent portion 31b is a portion for preventing the end edge of the outer rail portion 31 in the longitudinal direction from swinging, and a guide of the outer rail portion 31 to which the game ball fired from the game ball launching device 21 is guided. It is bent to the opposite surface side (rear surface side) of the surface 31c. Thereby, when the game ball fired from the game ball launching device 21 collides with the guide surface 31c of the outer rail portion 31, the edge of the outer rail portion 31 tilts to the opposite surface side (back side) of the guide surface 31c. Can be prevented.

  The guide portion reinforcing member 50 is provided at a position where the fitting pin 31 a is disposed between the bent portion 31 b and the guide portion reinforcing member 50. That is, the guide portion reinforcing member 50 is disposed between the fitting pins 31a. Since the fitting pins 31a are fixed to the outer rail portion 31 at appropriate intervals, the outer rail portion 31 is likely to swing between the fitting pins 31a. However, by arranging the guide portion reinforcing member 50 between the fitting pins 31a, it is possible to suppress the outer rail portion 31 from swinging between the fitting pins 31a.

  Next, the detailed configuration of the guide portion reinforcing member 50 will be described. As shown in FIGS. 11 and 13, the guide portion reinforcing member 50 is a member made of a synthetic resin, and formed in a substantially trapezoidal shape (as viewed from the side of the board of the game board 30) as viewed from the front 31. A base 51 positioned on the side opposite to the guide surface 31c, an opposite side projection 52 erected on the base 51, and a direction in which the opposite side projection 52 is erected. It is mainly provided with the fitting convex part 55 protrudingly provided from the base | substrate part 51 in the opposite direction.

  The base portion 51 is a plate-like portion that is in close contact with the surface of the game board 30 and disposed along the outer rail portion 31, and the opposite surface side protruding portion 52 stands substantially vertically to the base portion 51. It is a portion provided in the form of a wall at the edge of the base portion 51 as well as being provided. The opposite surface side projecting portion 52 is provided along the outer rail portion 31, and the base portion 51 is extended at the rear end side in the direction away from the outer rail portion 31. As a result, the base portion 51 and the opposite surface side protruding portion 52 are formed in a substantially L-shape in a side view.

  The opposite surface side projecting portion 52 is connected to the inclined portion 52a which is inclined downward from the top toward the base portion 51 side (panel surface side), and is connected to the inclined portion 52a and faces the outer rail portion 31 to at least one. And a contact portion 52b with which the portion contacts. A fitting convex portion 55 is provided in a projecting manner at one side edge of the base portion 51 and the opposite surface side projecting portion 52. Further, a rod-like columnar portion 53 is provided upright along the opposite surface side protruding portion 52 at the other side edge opposed to one side edge of the base portion 51 and the opposite surface side protruding portion 52. The columnar portion 53 is a portion for improving the bending rigidity of the opposite surface side protruding portion 52, is integrally formed with the base portion 51 and the opposite surface side protruding portion 52, and is located on the back surface side of the contact portion 52b. Thereby, compared with the thing in which the columnar part 53 is not formed, it can be made hard to bend and deform the opposite surface side projecting part 52 with respect to the axial direction of the columnar part 53. FIG.

  In the present embodiment, the columnar part 53 is formed in a cylindrical shape in which a hole (vertical hole 53 a) is formed substantially at the center along the axis of the columnar part 53. By forming the columnar portion 53 in a cylindrical shape in which the vertical hole portion 53a is formed, the torsional rigidity is improved as compared with a solid columnar portion (having the same outer diameter) in which the vertical hole portion 53a is not formed. At the same time, the columnar part 53 can be reduced in weight. As a result, as compared with the case where the columnar portion is formed in a solid shape in which the vertical hole portion 53a is not formed, the mass is excessively increased while the torsional rigidity of the opposite surface side projecting portion 52 is improved (hard to be deformed). Can be prevented.

  The columnar portion 53 has a substantially triangular reinforcing portion 54 extending in the axial direction of the outer peripheral edge. The reinforcing portion 54 is a member for reinforcing the columnar portion 53, and is set so that the cross-sectional area gradually increases from the top side toward the bottom side, and the bottom is set to be in close contact with the board of the game board 30. Ru. Since the substantially triangular reinforcing portion 54 is extended to the columnar portion 53 and the bottom of the columnar portion 53 is set in close contact with the surface of the game board 30, the columnar portion 53 can be further hardly bent and deformed.

  The base portion 51 is set such that the length of one side edge where the fitting convex portion 55 is provided is shorter than the length of the other side edge facing the one side edge. Since the other side edge of the base portion 51 is continuously provided on the bottom side of the columnar portion 53 and the reinforcing portion 54, the bottom area of the base portion 51 is gradually increased from one side edge to the other side edge of the base portion 51. It is set to become. By making the bottom area of the base 51 at a position far from the fitting projection 55 larger than the bottom area of the base 51 at a position near the fitting projection 55, the bottom of the position away from the fitting projection 55 Insufficient area can be prevented. As a result, it is possible to suppress the swing of the opposite surface side projecting portion 52 at a position far from the fitting convex portion 55.

  In addition, since the guide portion reinforcing member 50 is provided with the base portion 51 disposed along the outer rail portion 31, as shown in FIG. Can be shifted to the end (bent portion 31 b) side of the outer rail portion 31. As a result, the position of the fitting pin 31a for fixing the outer rail portion 31 to the game board 30 can be brought close to the position of the opposite surface side projecting portion 52 (contact portion 52b). By bringing the contact portion 52b closer to the fitting pin 31a for fixing the outer rail portion 31, it is possible to make the outer rail portion 31 less likely to bend between the fitting pin 31a and the contact portion 52b. As a result, the outer rail portion 31 can be effectively reinforced by the guide portion reinforcing member 50.

  The fitting convex portion 55 is a portion fitted to the hole 69 formed in the game board 30 in order to fix the guide portion reinforcing member 50 to the game board 30, and in the present embodiment, it is substantially circular. It is formed in a columnar shape. The fitting convex portion 55 is formed with a rounded reduced diameter portion 55a at its tip. The reduced diameter portion 55a is a portion set so that the area of the cross section orthogonal to the axis gradually decreases toward the tip end. Since the reduced diameter portion 55 a is formed, the fitting convex portion 55 can be easily inserted into the hole 69. Further, since the fitting convex portion 55 and the hole portion 69 are formed in a substantially circular shape in cross section, the fitting convex portion 55 can be made rotatable relative to the hole portion 69, and the guide portion reinforcing member 50 can be obtained. Fine positional adjustment when inserting into the hole 69 can be omitted. As a result, the workability of the operation of inserting the guide portion reinforcing member 50 into the hole portion 69 can be improved.

  The fitting convex portion 55 will be described with reference to FIG. FIG. 12 is a partially enlarged rear view of the game board 30 on which the guide portion (outer rail portion 31) and the guide portion reinforcing member 50 are installed. In FIG. 12, the position of the outer rail portion 31 disposed on the board of the game board 30 is illustrated by an imaginary line (two-dot chain line).

  As shown in FIG. 12, the fitting protrusion 55 includes a recess 56 in which a part of the outer peripheral surface is formed in a recess. Since a part of the outer peripheral surface of the fitting convex portion 55 is formed in a recessed shape by the concave portion 56, when the fitting convex portion 55 is fitted to the hole 69, the outer peripheral surface of the fitting convex portion 55 and the hole 69 The contact area with the inner circumferential surface of can be reduced. As a result, it is possible to increase the vertical effectiveness per unit area of the hole 69 and the fitting convex portion 55 when the fitting convex portion 55 is fitted in the hole 69. As a result, when fitting the fitting convex portion 55 into the hole 69, the hole 69 or the fitting convex portion 55 can be easily deformed (elastically or plastically deformed). The hole 69 can be easily fitted.

  Further, since the concave portion 56 is formed along the axial direction of the fitting convex portion 55, the effect of the concave portion 56 described above can be obtained along the axial direction of the fitting convex portion 55. Furthermore, since the recess 56 is formed from the distal end to the proximal end of the fitting projection 55, the effect of the recess 56 can be obtained from the distal end to the proximal end of the fitting projection 55.

  In the present embodiment, the concave portion 56 is formed in a slip shape from the tip end of the fitting convex portion 55 toward the proximal end. As a result, the fitting convex portion 55 can be fitted in the hole 69 by utilizing the elastic deformation of the fitting convex portion 55 due to the abrasion. Thereby, the fitting convex portion 55 can be easily fitted into the hole 69. Furthermore, by utilizing the elastic deformation of the fitting convex portion 55, it is possible to prevent a gap from being generated between the hole 69 and the fitting convex portion 55. As a result, it is possible to prevent the fitting convex portion 55 fitted in the hole 69 from rattling.

  Furthermore, in the present embodiment, the rubbing direction of the recess 56 as viewed from the axial direction (vertical direction in FIG. 12) of the fitting convex portion 55 is disposed non-parallel to the longitudinal direction of the outer rail portion 31. Thereby, when the guide surface 31c is pushed to the opposite surface side (the lower side in FIG. 12) by the gaming ball advancing toward the game area PE along the guide surface 31c of the belt-like outer rail portion 31, the fitting convex It is possible to make elastic deformation of the portion 55 difficult. This makes it difficult to tilt the guide portion reinforcing member 50.

  That is, the fitting convex portion 55 is unlikely to be elastically deformed by a load parallel to the rubbing direction, and is easily elastically deformed by a load orthogonal to the rubbing direction. When a load parallel to the rubbing direction is applied to the fitting convex portion 55, the fitting convex portion 55 is deformed so as to reduce the gap of the slit-like concave portion 56. Therefore, if the guide portion reinforcing member 50 is arranged such that the direction of friction of the fitting convex portion 55 is parallel to the longitudinal direction of the outer rail portion 31, the guide surface 31c of the outer rail portion 31 is pushed to the opposite side. When being done, the outer rail portion 31 tends to tilt due to the elastic deformation of the fitting convex portion 55. On the other hand, if the guide portion reinforcing member 50 is arranged such that the direction of the slip of the fitting convex portion 55 is not parallel to the longitudinal direction of the outer rail portion 31, the guide surface 31c of the outer rail portion 31 is the opposite surface. When pressed to the side, the fitting convex portion 55 can be made difficult to elastically deform. This makes it difficult to tilt the guide portion reinforcing member 50.

  In particular, by making the longitudinal direction of the outer rail portion 31 orthogonal to the rubbing direction of the concave portion 56, the fitting convex portion 55 can be most hardly elastically deformed by a load parallel to the rubbing direction. Thereby, as the outer rail portion 31 tilts, it is possible to suppress the guide portion reinforcing member 50 from tilting together. As a result, tilting of the outer rail portion 31 can be suppressed as the gaming ball advances, and the trajectory and flight distance of the gaming ball proceeding along the outer rail portion 31 can be stabilized.

  By making the longitudinal direction of the outer rail portion 31 and the direction of abrasion of the concave portion 56 non-orthogonal, it is possible to utilize elastic deformation of the fitting convex portion 55 by a load parallel to the direction of abrasion. is there. In particular, by making the longitudinal direction of the outer rail portion 31 parallel to the rubbing direction of the concave portion 56, it is possible to most actively utilize the elastic deformation of the fitting convex portion 55. As the outer rail portion 31 is tilted due to the progress of the game ball, the guide portion reinforcing member 50 (opposite surface side protruding portion 52) is tilted together to elastically deform the fitting convex portion 55, and the fitting convex portion 55 By the restoring force, it is possible to restore the guide portion reinforcing member 50 (opposite surface side protruding portion 52) and the outer rail portion 31 to their original positions. By utilizing the elastic deformation of the fitting convex portion 55, it is possible to suppress that the guide portion reinforcing member 50 is broken by the load (the load by the game ball) which is repeatedly input. As a result, it is possible to suppress that the guiding portion reinforcing member 50 can not restrict the tilting of the outer rail portion 31, and it is possible to stabilize the trajectory and the flight distance of the gaming ball traveling along the outer rail portion 31.

  Further, in the fitting convex portion 55, a concave portion 56a having a substantially circular cross section continuously formed with the concave portion 56 is formed at substantially the center of the fitting convex portion 55 along the axis (vertical direction in FIG. 12). ing. Since the concave portion 56a is formed, the cross-sectional area of the approximate center (near the axis) of the fitting convex portion 55 can be reduced. Thereby, the cross-sectional shape of the fitting convex part 55 of the both sides of the recessed part 56 in an axial direction view can be made into substantially fan shape. As a result, when a load parallel to the rubbing direction is applied to the fitting convex portion 55, the fitting convex portion 55 can be deformed so as to reduce the cross-sectional area of the recessed portion 56a. Thereby, the fitting convex part 55 can be fitted in the hole 69 by utilizing the elastic deformation of the fitting convex part 55 due to the concave portion 56a. Thereby, the fitting convex portion 55 can be easily fitted into the hole 69.

  The amount of elastic deformation of the fitting projection 55 due to the recess 56a is smaller than the amount of elastic deformation of the fitting projection 55 due to the recess 56. Therefore, the fitting projection in the rubbing direction (approximately vertical direction in FIG. 12) The amount of elastic deformation of 55 can be made different from the amount of elastic deformation of the fitting convex portion 55 in the direction (generally the left and right direction in FIG. 12) orthogonal to rubbing. Specifically, the elastic deformation amount of the fitting convex portion 55 in the rubbing direction (the substantially vertical direction in FIG. 12) is the elastic deformation of the fitting convex portion 55 in the direction orthogonal to the rubbing (the substantially horizontal direction in FIG. 12). It can be smaller than the amount. Therefore, it is possible to prevent loss of the effect of making it difficult to tilt the guide portion reinforcing member 50 when the recessed portion 56a is formed.

  In the end face of the projecting portion 68a in which the fitting pin 31a fixed to the outer rail portion 31 is inserted in the hole 68, a part of the end face is recessed from the hole 68 (inner peripheral surface) to the outer peripheral surface An end face groove 68b is formed. The end face grooves 68 b are formed in a direction along the longitudinal direction of the outer rail portion 31 disposed on the board surface of the game board 30. Since the end face groove 68b is formed on the end face of the projecting portion 68a, when the outer rail portion 31 is disposed on the game board 30, it is possible to make the direction in which the outer rail portion 31 is disposed erroneous.

  Referring back to FIG. As shown in FIG. 11, the guide portion reinforcing member 50 is disposed on the guide surface 31 c side of the outer rail portion 31 so as to face the opposite surface side projecting portion 52 and to be in contact with the guide surface 31 c. A section 57 is provided. As shown in FIG. 11 and FIG. 13, the guide surface side projecting portion 57 is projectingly provided on a part in the axial direction of the base end side (the front side in FIG. 11) of the fitting convex portion 55. A groove portion 58 into which the outer rail portion 31 is inserted is formed between the guide surface side projecting portion 57 and the opposite surface side projecting portion 52.

  Next, with reference to FIG. 14, the guide surface side projecting portion 57 and the groove portion 58 will be described. FIG. 14 is a cross-sectional view of the game board 30 taken along line XIV-XIV of FIG. As shown in FIG. 14, the guide surface side projecting portion 57 is disposed facing the opposite surface side projecting portion 52 at an interval substantially equal to the thickness of the outer rail portion 31. The opposite surface side projecting portion 52 is set to a height substantially the same as the height of the outer rail portion 31, but the guiding surface side projecting portion 57 is set to be lower than the height of the opposite surface side projecting portion 52 There is. Specifically, the height is set so as not to interfere with the game ball B moving along the outer rail portion 31.

  Since the guide portion reinforcing member 50 includes the guide surface side projecting portion 57, the outer rail portion 31 is held in the groove portion 58 between the opposite surface side projecting portion 52 and the guide surface side projecting portion 57. Since the outer rail portion 31 is held from both sides by the opposite surface side projecting portion 52 of the guide portion reinforcing member 50 and the guide surface side projecting portion 57, tilting of the outer rail portion 31 can be reliably prevented.

  Further, since the guide surface side projecting portion 57 disposed on the guide surface 31c side of the outer rail portion 31 is set to be lower than the height of the opposite surface side projecting portion 52, the game ball B along the guide surface 31c The guide surface side projecting portion 57 does not disturb the movement of the guide surface. When the game ball B interferes with the guide surface side projecting portion 57, a loss of kinetic energy of the game ball B occurs and the flight distance of the game ball B guided to the game area PE becomes unstable, but this can be prevented. The flight distance of the game ball B guided to the game area PE can be prevented from becoming unstable.

  In addition, as shown in FIG. 14, the concave portion 56 is scraped from the tip end (lower side in FIG. 14) of the fitting convex portion 55 while leaving the base end (base end 55 b) of the solid fitting convex portion 55. It is formed. Thus, the base end 55b of the solid fitting projection 55 can be fitted into the hole 69 (panel side). By fitting the base end 55b of the solid fitting convex portion 55 into the hole 69 (panel surface side), it is possible to prevent the rattling of the fitting convex portion 55 from occurring with respect to the hole 69. Furthermore, since the concave portion 56 is formed on the tip end side of the fitting convex portion 55, the elastic deformation or plastic deformation of the fitting convex portion 55 or the hole 69 can be facilitated, and the fitting convex portion 55 can be made into the hole 69 can be easily fitted.

  The gap between the outer peripheral surface of the fitting convex portion 55 (base end portion 55b) and the hole 69 is held by the groove 58 between the opposite surface side projecting portion 52 and the guide surface side projecting portion 57. The clearance is set to a smaller value than the clearance between the rail portion 31 and the opposite surface side projecting portion 52 or the guiding surface side projecting portion 57. When the outer rail portion 31 is fixed to the game board 30 while preventing rattling of the fitting convex portion 55 (base end portion 55b) inserted into the hole portion 69, the opposite surface side projecting portion 52 and the guide This is to facilitate the insertion of the outer rail portion 31 into the groove portion 58 between the surface side protruding portions 57. Since the outer rail portion 31 is fixed to the game board 30 by the fitting pins 31a even if a gap is formed between the opposite surface side protruding portion 52 or the guide surface side protruding portion 57 and the outer rail portion 31, The rattling of the outer rail portion 31 with respect to the game board 30 can be prevented.

  As described above, the guide portion reinforcing member 50 for restricting the tilting of the outer rail portion 31 has the fitting convex portion 55 fitted in the hole portion 69 formed in the recess shape on the board surface of the game board 30, and the fitting convex portion thereof. An opposite surface side projecting portion 52 is provided to project from the portion 55 and to be in contact with the opposite surface side of the guide surface 31 c of the outer rail portion 31. In the guide portion reinforcing member 50, an opposite surface side projecting portion in which the fitting convex portion 55 is fitted in the hole portion 69 formed in a depression shape on the surface of the game board 30, and the projecting portion 55 is provided. 52 contacts the opposite surface side of the guide surface 31 c of the outer rail portion 31. Accordingly, it is possible to suppress the belt-like outer rail portion 31 from being tilted outward by the guide surface 31c being pushed to the opposite surface side by the gaming ball advancing toward the game area PE along the guide surface 31c. Since tilting of the outer rail portion 31 for guiding the game balls to the game area PE can be suppressed, it is possible to stabilize the trajectory and the flight distance of the game balls guided to the game area PE.

  That is, when the guide surface 31c is pushed to the opposite surface side by the game ball advancing toward the game area PE along the guide surface 31c and the belt-like outer rail portion 31 tilts, the trajectory of the game ball changes or the game ball Loss of kinetic energy occurs. As a result, the trajectory and flight distance of the gaming ball guided to the gaming area PE may be unstable.

  On the other hand, according to the present embodiment, the guide surface reinforcing member 50 is disposed such that the opposite surface side protruding portion 52 is in contact with the surface opposite to the surface 31c of the outer rail portion 31. It is possible to suppress tilting of the outer rail portion 31 by the game balls advancing toward the game area PE along 31c. This makes it possible to stabilize the trajectory and flight distance of the gaming ball guided to the gaming area PE.

  In addition, since the fitting convex portion 55 includes the concave portion 56 in which a part of the outer peripheral surface is formed in a dent shape, the fitting convex portion 55 when the fitting convex portion 55 is fitted in the hole 69 The contact area between the outer peripheral surface and the inner peripheral surface of the hole 69 can be reduced. As a result, it is possible to increase the vertical effectiveness per unit area of the hole 69 and the fitting convex portion 55 when the fitting convex portion 55 is fitted in the hole 69. As a result, when fitting the fitting convex portion 55 into the hole 69, the hole 69 or the fitting convex portion 55 can be easily deformed (elastically or plastically deformed). The hole 69 can be easily fitted.

  In addition, since the concave portion 56 is formed in a shape of rubbing from the tip end of the fitting convex portion 55 toward the base end (proximal end portion 55b), using elastic deformation of the fitting convex portion 55 due to rubbing. The fitting protrusion 55 can be fitted in the hole 69. As a result, the fitting convex portion 55 can be easily fitted into the hole 69, and by utilizing elastic deformation of the fitting convex portion 55, generation of a gap between the hole 69 and the fitting convex portion 55 is prevented. Since this can be done, it is possible to make the fitting convex portion 55 fitted in the hole 69 less likely to rattle.

  In addition, since the direction of abrasion of the concave portion 56 viewed from the axial direction of the fitting convex portion 55 is disposed not in parallel with the longitudinal direction of the outer rail portion 31, along the guide surface 31 c of the belt-like outer rail portion 31 When the guide surface 31c is pushed to the opposite surface side by the game ball advancing toward the game area PE, the fitting convex portion 55 can be made difficult to elastically deform. Thereby, tilting of the outer rail portion 31 can be suppressed. As a result, it is possible to further stabilize the trajectory and flight distance of the gaming ball guided to the gaming area PE.

  Further, since the guide portion reinforcing member 50 is provided with the guide surface side projecting portion 57 facing the opposite surface side projecting portion 52, the outer rail portion 31 is held from both the guide surface 31c and the opposite surface. Thereby, tilting of the outer rail portion 31 can be reliably prevented. As a result, it is possible to further stabilize the trajectory and flight distance of the gaming ball guided to the gaming area PE. Furthermore, since the guide surface side projecting portion 57 is set to be lower than the height of the opposing surface side projecting portion 52 facing each other, interference between the game ball and the guide surface side projecting portion 57 along the guide surface 31 c is prevented. it can.

  Further, the opposite surface side protruding portion 52 is connected to the inclined portion 52a which is inclined downward from the top toward the axial direction outer side of the fitting convex portion 55, and the inclined portion 52a and the opposite surface of the outer rail portion 31. Since it is provided with the contact part 52b which at least one part of an opposite surface contacts while facing it, the operation | work which arrange | positions the guide part reinforcement member 50 and the outer rail part 31 on the board surface of the game board 30 can be facilitated.

  That is, when arranging the guide portion reinforcing member 50 and the outer rail portion 31 on the board surface of the game board 30, first, about half the length of the fitting convex portion 55 of the guide portion reinforcing member 50 Insert in the hole 69. Since the concave portion 56 is formed in the fitting convex portion 55 in a slip shape, the fitting convex portion 55 is formed so as to narrow the gap between the concave portions 56 when inserted into the hole 69 of the game board 30. Deform. Therefore, the operation of inserting about half of the length of the fitting projection 55 into the hole 69 of the game board 30 can be facilitated.

  Next, the outer rail portion 31 is disposed along the inclined portion 52 a of the opposite surface side protruding portion 52 so that the outer rail portion 31 faces the contact portion 52 b of the guide portion reinforcing member 50. The inclined portion 52a is inclined downward from the top toward the axial direction outer side of the fitting convex portion 55, and the contact portion 52b is provided continuously with the inclined portion 52a, so the outer rail portion 31 is formed along the inclined portion 52a. Can be smoothly disposed to the contact portion 52b.

  When the outer rail portion 31 is moved in a direction perpendicular to the board surface of the game board 30 to bring the outer rail portion 31 closer to the game board 30, if the side edge of the outer rail portion 31 abuts the inclined portion 52a, the outer rail As the section 31 approaches the game board 30, the inclined part 52a is pushed in the horizontal direction with respect to the board surface, and the guiding part reinforcing member 50 rotates around the fitting convex part 55. When the outer rail portion 31 separates from the inclined portion 52a and faces the contact portion 52b, no force for rotating the guide portion reinforcing member 50 is generated, so the position of the guide portion reinforcing member 50 is determined.

  Further, while fitting the outer rail portion 31 in the groove portion 58 between the contact portion 52b and the guide surface side protruding portion 57, the fitting pin 31a fixed to the outer rail portion 31 is inserted into the hole portion 68. Go. As the fitting pin 31a is inserted into the hole 68, the base end face of the fitting protrusion 55 is pushed to the side edge of the outer rail portion 31, and the fitting protrusion 55 is gradually fitted into the hole 69 . Thereby, the workability of the arrangement operation of arranging the outer rail portion 31 on the board of the game board 30 can be improved.

  In addition, since the base end 55 b of the fitting convex portion 55 is formed in a solid shape, the base end 55 b is fitted into the hole 69. Thereby, it is possible to prevent the fitting convex portion 55 from rattling in the hole 69.

  Further, since the protrusion 69a is projected toward the back side in the thin portion 72 of the game board 30, and the hole 69 is formed through the protrusion 69a and the thin portion 72, the protrusion 69a is fitted in the hole 69. The fitting depth of the fitting convex portion 55 can be secured. As the fitting depth of the fitting projection 55 fitted in the hole 69 increases, the fitting projection 55 fitted in the hole 69 tends to be less likely to swing in the direction orthogonal to the axial direction. Since it can be seen, securing the fitting depth of the fitting convex portion 55 to be fitted in the hole 69 makes it difficult for the guide portion reinforcing member 50 fixed to the game board 30 to swing. By making it difficult to swing the guide portion reinforcing member 50 fixed to the game board 30, tilting of the outer rail portion 31 for guiding the game ball to the game area PE can be suppressed, so the game ball guided to the game area PE The trajectory and flight distance can be further stabilized.

  Further, since the projection 69a is coupled to the thin portion 72 and the hole 69 is formed to penetrate through the projection 69a and the thin portion 72, the area of the thick portion 70 is enlarged to form the hole 69. It can be unnecessary. Although the mass of the game board 30 is increased by the amount of the protrusion 69a (excluding the hole 69) coupled to the thin portion 72, it is not necessary to widen the area of the thick portion 70. The increase can be suppressed. Furthermore, since the protrusion 69a in which the hole 69 is formed penetrates and functions as a rib that enhances the rigidity of the thin portion 72 around the hole 69, the rigidity of the thin portion 72 around the hole 69 can be secured. Therefore, it is possible to implant the nail in the thick portion 70 to secure the holding power of the nail and to reduce the weight of the game board 30 while securing the rigidity of the game board 30. In addition, the trajectory and flight distance of the gaming ball guided to the gaming area PE can be further stabilized.

  Next, referring to FIG. 15, a guide reinforcing member 50 in another embodiment will be described. The same parts as those in the first embodiment are given the same reference numerals, and the description thereof will be omitted. FIG. 15 (a) is a partially enlarged rear view of the game board 30 on which the guide portion reinforcing member 80 according to the other embodiment is installed, and FIG. 15 (b) is a game on which the guide portion reinforcing member 90 according to the other embodiment is installed. FIG. In FIGS. 15 (a) and 15 (b), the fitting convex portions 85 and 95 of the guide portion reinforcing members 80 and 90 are fitted in the holes 69 formed in the game board 30 from the board surface (front side) side. And the state seen from the back side of the game board 30 is illustrated.

  The guide portion reinforcing member 80 shown in FIG. 15 (a) is a part of the outer peripheral surface along the axial direction (the direction perpendicular to the paper surface of FIG. 15 (a)) at two axially symmetrical positions of the outer peripheral surface of the fitting projection 85. Is provided with a recess 86 formed in the shape of a recess. Since the fitting convex portion 85 includes the recess 86 in which a part of the outer peripheral surface is formed in a dent shape, the outer peripheral surface of the fitting convex portion 85 when the fitting convex portion 85 is fitted in the hole 69 The contact area between the inner surface and the inner peripheral surface of the hole 69 can be reduced. As a result, it is possible to increase the vertical effectiveness per unit area of the hole 69 and the fitting convex portion 85 when the fitting convex portion 85 is fitted in the hole 69. Thus, when fitting the fitting convex portion 85 into the hole 69, the hole 69 or the fitting convex portion 85 can be easily deformed (elastically or plastically deformed). The hole 69 can be easily fitted.

  In addition, a recessed portion 85a having a circular cross section is formed substantially at the center of the fitting protrusion 85 along the axial direction of the fitting protrusion 85 from the tip of the fitting protrusion 85. By reducing the cross-sectional area of the fitting convex portion 85 by the concave portion 85a, the fitting convex portion 85 can be easily elastically deformed by the vertical force acting on the fitting convex portion 85. As a result, the fitting convex portion 85 can be further easily fitted to the hole 69, so that the workability when the fitting convex portion 85 is fitted to the hole 69 can be improved. Furthermore, by making the fitting convex portion 85 easily elastically deformable, it is possible to prevent the rattling of the fitting convex portion 85 with respect to the hole 69.

  In particular, since the recess 86 is formed in such a shape that two places are cut out along the axial direction of the fitting protrusion 85, the outer peripheral surface of the fitting protrusion 85 is prevented from becoming excessively small, A contact area with the inner peripheral surface of the hole 69 can be secured. Since the vertical effectiveness per unit area of the outer peripheral surface of the fitting convex portion 85 can be prevented from being excessive, deformation such as buckling of the outer peripheral surface of the fitting convex portion 85 can be suppressed. As a result, a gap is generated between the outer peripheral surface of the fitting convex portion 85 and the inner peripheral surface of the hole 69, and the occurrence of problems such as rattling of the fitting convex portion 85 can be suppressed.

  The guide portion reinforcing member 90 shown in FIG. 15 (b) is a part of the outer peripheral surface along the axial direction (the direction perpendicular to the paper surface of FIG. 15 (b)) at four positions in axial symmetry of the outer peripheral surface of the fitting projection 95 Is provided with a recess 96 formed in the shape of a recess. Since the fitting convex portion 95 includes the concave portion 96 in which a part of the outer peripheral surface is formed in a dent shape, the outer peripheral surface of the fitting convex portion 95 when the fitting convex portion 95 is fitted in the hole 69 The contact area between the inner surface and the inner peripheral surface of the hole 69 can be reduced. As a result, it is possible to increase the vertical effectiveness per unit area of the hole 69 and the fitting convex 95 when the fitting convex 95 is fitted in the hole 69. Thus, when fitting the fitting convex portion 95 into the hole 69, the hole 69 or the fitting convex portion 95 can be easily deformed (elastically or plastically deformed). The hole 69 can be easily fitted.

  In addition, a concave portion 95a having a circular cross section is formed at substantially the center of the fitting convex portion 95 along the axial direction of the fitting convex portion 95 from the tip of the fitting convex portion 95. By reducing the cross-sectional area of the fitting convex portion 95 by the concave portion 95 a, the fitting convex portion 95 can be easily elastically deformed by the vertical force acting on the fitting convex portion 95. As a result, the fitting convex portion 95 can be further easily fitted into the hole 69, so that the workability when the fitting convex portion 95 is fitted into the hole 69 can be improved. Furthermore, the elastic deformation of the fitting convex portion 95 makes it possible to prevent the rattling of the fitting convex portion 95 with respect to the hole 69.

  Next, a second embodiment will be described with reference to FIG. In the first embodiment, the outer peripheral edge of the opening 61 formed in the thickness direction of the game board 30 is continuous inside the outer peripheral edge of the game board 30 (the outer peripheral edge of the game board 30 is closed) The case was explained. On the other hand, in the second embodiment, the case where the opening portion 161 is formed to penetrate in the thickness direction of the gaming board 130 and a part of the outer peripheral edge of the gaming board 130 is opened will be described. The same parts as those in the first embodiment are given the same reference numerals, and the description thereof will be omitted. FIG. 16 is a front view of the game board 130 and the structure 170 which are the main components of the pachinko machine 1 according to the second embodiment.

  As shown in FIG. 16, the game board 130 is formed through in the thickness direction (vertical direction in FIG. 16) of the game board 130 and at the same time an opening 161 where a part of the outer periphery of the game board 130 is opened And a structure 170 for connecting the peripheries of the opening 161. In the present embodiment, a part of the outer peripheral edge of the game board 130 located on the right side in a front view is opened by the opening 161. By forming the opening 161, the game board 130 is formed to have a substantially C-shaped board surface.

  The structure 170 is connected between one predetermined portion 161 a of the periphery of the opening 161 of the game board 130 and the other predetermined portion 161 b. In the present embodiment, the structure 170 is formed in a substantially rectangular shape as viewed from the front, and connects two places of the opening 161 along the outer peripheral edge of the game board 130. In addition, the game board 130 and the structure 170 are formed of the synthetic resin which has translucency similarly to the game board 30 demonstrated in 1st Embodiment. Further, inside the opening 161 in which a part of the outer peripheral edge is closed by the structure 170, a symbol display device 43a (see FIG. 5) is disposed as in the first embodiment.

  Next, with reference to FIG. 17, the connection structure between the game board 130 and the structure 170 will be described. FIG. 17 is a perspective view of the game board 130 and the structure 170. As shown in FIG. In addition, in FIG. 17, the state which isolate | separated the structure 170 with respect to the game board 130 is shown. As shown in FIG. 17, the structure 170 projects from both the upper and lower sides (substantially parallel to the board of the game board 30) from the front side of the main body 172 formed in a substantially rectangular box shape and the front side of the body 172 It mainly comprises an engaging portion 171 formed in a bowl shape.

  A symbol display device (not shown) for variably displaying a plurality of symbols is incorporated in the main body portion 172, and a symbol display portion 173 (decorative portion) such as a liquid crystal display is disposed on the front surface of the main body portion 172 . The symbol display portion 173 is not limited to the liquid crystal display, and a CRT, a dot matrix, a 7-segment display, and other display screens can be appropriately selected.

  An insertion hole 174 into which an axial member such as a screw for fixing the structure 170 to the game board 130 is screwed is formed in the engaging portion 171.

  In the game board 130, a connecting portion (engaged portion) 131 for receiving an engaging portion 171 provided on the structure 170 is formed on a part of the periphery of the opening portion 161. The connecting portion 131 is a portion for engaging with the engaging portion 171 provided on the structure 170 to position the structure 170.

  In the present embodiment, the connecting portion 131 is provided as a step-like flat surface set one step lower than the board surface of the game board 130. The depth (lateral direction in FIG. 17) of the connecting portion 131 with respect to the board of the gaming board 130 is set to be substantially the same as the thickness (lateral direction in FIG. 17) of the engaging portion 171.

  In addition, a light scattering portion 132 is provided on the back side of the connecting portion 131. The light scattering portion 132 is a portion for scattering light emitted from the light emitting portion 181 (described later) such as an LED disposed on the back side of the game board 130 to the game board 130. The light scattering portion 132 is formed by a ridge provided in the vertical direction or the horizontal direction, a ridge provided in the direction crossing the vertical and horizontal directions, or a wavelike protrusion.

  In addition, in the connecting portion 131, an insertion hole 133 in which an insertion hole 174 formed in the structure 170 (engagement portion 171) is axially connected and an axial member such as a screw is screwed is formed. The structure 170 can be connected to the game board 130 by connecting the connecting portion 131 and the engaging portion 171 by shaft-like members such as screws screwed into the insertion holes 133 and 174.

  Next, the light scattering portion 132 will be described with reference to FIG. The light scattering portion 132 is formed on the back side of the connecting portion 131 as a portion such as a protrusion or a protrusion. A support 180 is installed on the back side of the connecting portion 131 (game board 130), and light emitting portions 181 such as a plurality of LEDs are scattered in the surface direction of the support 180.

  The light emitted from the light emitting portion 181 (indicated by a two-dot chain line in FIG. 18) enters and leaves the light scattering portion 132 (engaged portion 131) due to the difference in the refractive index between air and the light scattering portion 132. When it refracts. Therefore, by causing the light emitting portion 181 to emit light, it is possible to realize lighting in a state in which light is dispersed in a large number or in a state with a three-dimensional effect. Thereby, in addition to the rendering effect by the symbol display portion 173 (decoration portion), the rendering effect by the light from the light emitting portion 181 can be improved.

  Further, by providing the light scattering portion 132 on the back side (back side) of the game board 130 (connecting portion 131), the light scattering portion 132 can be integrally formed with the game board 130 when the game board 130 is formed. As a result, the light scattering portion 132 can be easily manufactured.

  When the light scattering portion 132 is provided by processing the surface (front surface) of the game board 130 into a protrusion or a projection, the unevenness of the light scattering portion 132 interferes with the movement of the game ball, When the light scattering portion 132 is provided on the back surface (back surface) of the game board 130, it is not necessary to consider the interference of the movement of the gaming ball by the light scattering portion 132 (concave and convex). Thereby, flexibility of design of the game board 130 can be secured.

  Further, when the light scattering portion 132 is provided on the back surface side (back surface) of the game board 130 (connection portion 131), the shape of the light scattering portion 132 can be designed relatively freely. Since the outer periphery reinforcing rib 73 (see FIG. 17) standing up toward the back side is provided on the outer periphery of the game board 130, the outer periphery reinforcing rib 73 is used on the back side (back side) of the game board 130. It is because a space can be secured.

  In addition, by scattering light by the light scattering portion 132, the shadow of a shaft-like member (not shown) such as a screw screwed into the insertion holes 133 and 174 is from the front surface of the game board 130 or the front surface of the structure 170. It can be prevented from being viewed. By scattering the light by the light scattering portion 132, it is possible to cause the light to wrap around in front of the axial member (not shown). Thus, it is possible to make it difficult to visually recognize the joint portion (connecting portion 131 and engaging portion 171) between the game board 130 and the structure 170 by the light scattered by the light scattering portion 132. It is possible to improve the rendering effect of the joint portion.

  On the other hand, according to the present embodiment, the game board 130 is manufactured by using the synthetic resin game board 130 in which the opening portion 161 in which the peripheral portion (the peripheral portion reinforcing rib 73) is opened is formed. A three-dimensional structure 170 using a space in the thickness direction can be adopted. As a result, it is possible to implement a three-dimensional effect utilizing the space in the thickness direction of the game board 130. This makes it possible to greatly enhance the interest of the game.

  In addition, a symbol display device 43a (see FIG. 5) having a display portion for variably displaying symbols is provided in the opening portion 161, and the structure 170 is arranged around the symbol display device 43a. The three-dimensional effect utilizing the space in the thickness direction of the game board 130 can be realized by the symbol display portion 173 (decorative portion) 170 as well as the planar symbol effect of the symbol display device 43a. Furthermore, since the structure 170 is unitized as a game component having the symbol display portion 173 (decoration portion), attachment of the structure 170 to the game board 130, replacement work, and the like can be easily performed.

It is penetratingly formed along (FIG. 29 (a) vertical direction in the drawing). The protrusions 532a and 532b provided on the end face in the axial direction of the rail receiver 532 are disposed on the side of the board surface 530a from the board side 530a to the thickness direction of the game board 530 (FIG. 29 (a) perpendicular to the paper surface) When projected in the direction, it is provided at a position which does not interfere with the projection line of the inner rail portion 32 shown in the orthogonal plane (the plane of FIG. 29A) orthogonal to the thickness direction of the game board 530.

  The rail receiver 533 is provided in the thin portion 72 of the game board 530, and a hole 68 for mounting the outer rail portion 31 is formed to penetrate along the axial direction (vertical direction in FIG. 29A). ing. As shown in FIG. 29 (b), the rail receiver 533 has a flat-surfaced receiver 533 a formed on the end face in the axial direction. The distance from the panel surface 530a to the receiving portion 533a (the height of the rail receiver 533) is set to a value smaller than the distance from the panel surface 530a to the end face of the outer peripheral edge reinforcing rib 531 (height of the outer peripheral edge reinforcing rib 531) . Further, the height of the rail receiver 533 is set to the same value as the distance from the board surface 530 a to the receiver 532 c of the rail receiver 532 (the height of the receiver 532 c).

  The end face in the axial direction of the projecting portion 69a holding the fitting convex portion 55 of the guide portion reinforcing member 550 and the end face formed in the axial direction end face of the projecting portion 68a holding the fitting pin 31a of the outer rail portion 31 The groove 68b (see FIG. 12) also functions as a receiving portion of the rail receiving portion (a part of the rear side contact portion). The height from the board 530a is also set to the same value as the height of the receiving portion 532c.

  Next, FIG. 30 (a) is a partially enlarged rear view of the game board 530 showing a portion shown by XXXa in FIG. 26 in an enlarged manner, and FIG. 30 (b) is a game board viewed from the direction of arrow XXXb in FIG. FIG. 53 is a partial enlarged side view of 530. In FIG. 30 (a), the outer rail portion 31 disposed on the board of the game board 530 (the surface on the back side of the plane of FIG. 30 (a)) is shown by a broken line.

  As shown in FIGS. 30 (a) and 30 (b), the rail receiver 532 is provided on the inclined surface 71 of the game board 530, and the hole 68 for mounting the outer rail 31 is in the axial direction. It is penetratingly formed along (FIG. 30 (a) vertical direction in the drawing). The protrusions 532a and 532b provided on the end face in the axial direction of the rail receiver 532 are disposed on the side of the board surface 530a from the board side 530a to the thickness direction of the game board 530 (FIG. 29 (a) perpendicular to the paper surface) When projected in the direction, it is provided at a position which does not interfere with the projection line of the outer rail portion 31 shown in the orthogonal plane (the plane of FIG. 29A) orthogonal to the thickness direction of the game board 530.

  The rail receiver 534 is formed in the vicinity of a reference hole 534a (see FIG. 30) serving as a positioning reference in the manufacturing process of the game board 530 and the like, and is connected to the outer peripheral edge reinforcing rib 531. The rail receiver 534 is a portion for receiving the side edge of the outer rail portion 31 of another game board 530 when stacking a plurality of game boards 530 on which the outer rail portion 31 and the inner rail portion 32 are mounted. The rail receiver 534 has a semi-cylindrical shape, and protrudes from the back surface of the game board 530 along the thickness direction of the game board 530 (vertical direction in FIG. 30A).

  The rail receiver 534 has a flat receiving surface 534b as a surface substantially parallel to the outer peripheral reinforcing rib 531 along the thickness direction of the game board 530 (the direction perpendicular to the sheet of FIG. 30A). Is formed. At the lower end of the receiving surface 534b, a receiving portion 534c is extended toward the inside of the game board 530. The receiving portion 534c has a thickness of the game board 530 when the outer rail portion 31 disposed on the board surface 530a is projected from the board surface 530a in the thickness direction of the game board 530 (the vertical direction in FIG. 30A). It is provided so as to overlap a part of the projection line of the outer rail portion 31 shown in the orthogonal plane orthogonal to the direction (the plane of FIG. 30A).

  As shown in FIG. 30 (b), the distance from the panel surface 530a to the axial end surface of the rail receiver 534 (height of the rail receiver 534) is the distance from the panel surface 530a to the end surface of the outer peripheral edge reinforcing rib 531 (outer peripheral edge reinforcement (The height of the rib 531). Further, the distance from the board surface 530a to the receiving portion 534c (the height of the receiving portion 534c) is set to a value smaller than the height of the outer peripheral edge reinforcing rib 531. The height of the receiving portion 534c is set to the same value as the distance from the board surface 530a to the receiving portion 532c of the rail receiving portion 532 (the height of the receiving portion 532c). Since the receiving portion 534c is coupled to the upper side of the outer periphery reinforcing rib 531 of the game board 530, the stability of regulating the position when stacking the game board 530 is excellent.

  Next, FIG. 31 (a) is a partially enlarged rear view of the game board 530 showing a portion shown by XXXIa in FIG. 26 in an enlarged manner, and FIG. 31 (b) is at the line XXXIb-XXXIb in FIG. 31 (a). It is a cutting part end view. In FIG. 31 (a), the inner rail portion 32 disposed on the surface of the game board 530 (the surface on the back side of the plane of FIG. 31 (a)) is shown by a broken line.

  As shown in FIG. 31 (a), the rail receiver 532 is provided on the inclined surface 71 of the game board 530, and the hole 68 for mounting the inner rail 32 has an axial direction (FIG. 31 (a)). (Perpendicular to the paper surface). Annular reinforcing ribs 535 are erected on the back of the game board 530 around the out port 39, and holes 68 are formed on the left and right sides of the out port 39, respectively. As a result, the inner rail portion 32 can be firmly fixed to the game board 530 on both sides of the out-port 39 where game balls that can not enter the ball are provided in the game area PE.

  The inner rail portion 32 is provided with a protruding portion 32a in which the inner rail portion 32 is bent toward the outer peripheral edge side of the game board 530 at the position of the out port 39. The overhanging portion 32a is a part for facilitating the flow of the gaming ball into the out port 39, and the gaming ball which has flowed down the gaming area PE and reached the lower end of the inner rail portion 32 is outported by the overhanging portion 32a. It can flow into 39 quickly.

  The reinforcing rib 535 is provided with relief portions 535a at the left and right positions of the out port 39, and wall portions 535b are provided upright on both sides of the relief portion 535a. The relief portion 535a has a thickness of the game board 530 when the inner rail portion 32 disposed on the board surface 530a is projected from the board surface 530a in the thickness direction of the game board 530 (the vertical direction in FIG. 31A). It is provided at a position intersecting with the projection line of the inner rail portion 32 shown in the orthogonal plane orthogonal to the direction (the plane of FIG. 31 (a)). The width of the relief 535a defined by the wall 535b (the vertical direction in FIG. 31A) is set to be larger than the width of the receiving portion 532c.

  As shown in FIG. 31 (b), the relief 535 a is provided closer to the board surface 530 a than the receiving portion 532 c of the rail receiver 532. The distance from the panel surface 530a to the axial end surface of the rail receiver 532 (height of the rail receiver 532) is set to be the same as the distance from the panel surface 530a to the end surface of the reinforcing rib 535 (height of the reinforcing rib 535). Further, the distance from the board surface 530a to the relief part 535a (the height of the relief part 535a) is set to the same value as the distance from the board surface 530a to the receiving part 532c (the height of the receiving part 532c).

  Next, with reference to FIG. 32 and FIG. 33 (a), the state when the plurality of game boards 530 are stacked will be described. FIG. 32 and FIG. 33 (a) are end views of the cutting section schematically showing a state in which a plurality of gaming boards 530 are stacked. In the manufacturing process of the game board 530, first, the hole 68 for attaching the fitting pins 31a, 32a and the like and the nail (obstacle nail) 536 are inserted into the board material made of synthetic resin for the game board. A pilot hole (mounting hole) is formed. Next, a nail 536 is implanted, and a small part (not shown) such as a wind turbine, and the outer rail portion 31 and the inner rail portion 32 are attached. Next, large parts (not shown) such as a large winning device and a control circuit board are assembled. In assembling large parts, the process becomes complicated because the work becomes complicated. Due to the imbalance of the process capability, the game board 530 in the process of manufacture may temporarily stay between processes. In such a case, the game board 530 in the process of manufacture to which the nail 536, the outer rail portion 31 and the inner rail portion 32 are attached is temporarily stacked, and the stagnated game board 530 waiting for the next process is made to wait.

  In the game board 530, the height of the outer peripheral reinforcing rib 531, the heights of the rail receivers 532 and 534, and the height of the reinforcing rib 535 are set to the same value with respect to the board surface 530a. It can be placed flat on the flat surface G of the waiting place with the back side facing downward. Further, the outer peripheral reinforcing rib 531 is provided so as to protrude all around the thin portion 72, and the rail receivers 532 and 534 and the reinforcing rib 535 are dispersed around the thick portion 70 formed in a substantially circular shape. The load can be dispersed and carried on the outer peripheral reinforcing rib 531, the rail receivers 532 and 534, and the reinforcing rib 535.

  When stacking another game board 530 on the game board 530 placed flat on the flat surface G, the other side of the outer rail portion 31 and the inner rail portion 32 erected on the board surface 530 a of the game board 530 The receivers 532c, 533a, 534c of the rail receivers 532 533 534 of the game board 530 are brought into contact. Further, the side edges of the outer rail portion 31 and the inner rail portion 32 are brought into contact with the outer peripheral rail receivers 531 c and 531 d (see FIG. 33) of the other game boards 530. The belt-like outer rail portion 31 and the inner rail portion 32 are configured to have the same width, and the receiving portions 532c, 533a, 534c and the outer peripheral rail receivers 531c, 531d are set to the same height with respect to the board surface 530a. The game board 530 can be stably placed on the side edges of the outer rail portion 31 and the inner rail portion 32 via the receiving portions 532c, 533a, 534c and the outer peripheral rail receivers 531c, 531d.

  By repeating this, the game boards 530 can be stacked one after another. As a result, the outer rail portion 31 and the inner rail portion 32 receive the load of the stacked upper game board 530, so the nails 536 implanted on the board surface 530a of the game board 530 do not contact the back of the game board 530. In this case, the load on the upper game board 530 applied to the nails 536 of the stacked lower game board 530 can be made zero. In addition, even when the nail 536 implanted on the board surface 530a of the game board 530 contacts the back of the game board 530, the load of the upper game board 530 applied to the nail 536 of the stacked lower game board 530 can be It can be dispersed and made small in the receivers 532, 533, 534, the outer peripheral rail receivers 531c, 531d, the outer rail portion 31, and the inner rail portion 32. Thereby, when the game boards 530 are stacked, it is possible to prevent an adverse effect such as bending of a nail 536 implanted on the game board 530.

  The outer rail portion 31 and the inner rail portion 32 are arranged on the board surface 530a of the game board 530 by curving them in an arc shape when the board surface 530a is viewed from the front, so the thickness direction of the game board 530 (FIG. 32 vertical direction The rigidity of) can be secured. Therefore, when the load of the stacked upper game board 530 is applied to the outer rail portion 31 and the inner rail portion 32, it is possible to prevent the occurrence of a defect such as bending of the outer rail portion 31 and the inner rail portion 32. Therefore, it is possible to stack the game boards 530 without adversely affecting the nails 536, the outer rails 31, and the inner rails 32 embedded in the board 530a.

  In addition, the rail receptacles 532 533 534 (receiving parts 532 c 533 a 534 c) are formed when the plurality of game boards 530 are stacked such that the back surface of the game board 530 and the board surface 530 a of another game board 530 face each other. The height of the game board 530 in the thickness direction is set such that the nails 536 implanted on the board surface 530 a do not contact the back surface of the game board 530. As a result, the load on the upper game board 530 applied to the nails 536 of the stacked lower game board 530 can be made zero. As a result, when the gaming boards 530 are stacked, it is possible to reliably prevent an adverse effect such as bending of the nail 536 implanted on the gaming board 530.

  Further, since the rail receivers 532, 533, 534 (receivers 532c, 533a, 534c) (rear side contact portions) are provided on the back surface of the game board 530, the projection length of the nail 536 from the board surface 530a is The height of the rail portion 31 and the inner rail portion 32 can be the same or larger. In that case, when the game board 530 is attached to the main frame 3 (see FIG. 2) and the front door frame 4 is closed to constitute the pachinko machine 1, the back of the glass 14 attached to the front door frame 4 and the nail 536 The gap with the tip (end) can be reduced. Therefore, it is possible to suppress occurrence of a problem that the gaming ball is caught between the back surface of the glass 14 and the tip of the nail 536 during the game.

  In the rail receivers 532 and 534, receiving surfaces 532a1, 532b1 and 534b along side surfaces in the longitudinal direction of the outer rail portion 31 and the inner rail portion 32 project from the receiving portions 532c and 534c in the thickness direction of the game board 530 It is done. Thus, when the positions of the stacked game boards 530 are shifted in the direction orthogonal to the longitudinal direction of the outer rail portion 31 and the inner rail portion 32, the receiving surfaces 532a1, 532b1, 534b form the outer rail portion 31 and the inner rail portion 32. At the end, further positional deviation of the game board 530 is prevented. As a result, the state in which the side edges of the outer rail portion 31 and the inner rail portion 32 abut on the receiving portions 532 c and 534 c can be maintained, so that sliding of the stacked upper game boards 530 can be suppressed.

  Further, in the outer rail portion 31 and the inner rail portion 32, fitting pins 31a and 32a are provided protruding outward in the width direction of the outer rail portion 31 and the inner rail portion 32 from their side edges. On the other hand, the game board 530 is formed with a hole 68 into which the fitting pins 31a and 32a are fitted, and the fitting pin 31a and 32a is fitted into the hole 68, whereby the outer rail 31 and the inside of the game board 530 are formed. The rail portion 32 is attached. Since the holes 68 are formed at the positions of the rail receivers 532 533, the depth of the holes 68 can be secured by the height of the rail receivers 532 533 in the thickness direction of the game board 530. Thus, the holding force of the fitting pins 31a and 32a inserted into the hole 68 can be increased. Therefore, the outer rails 31 and the inner rails 32 can be firmly fixed to the game board 530 by firmly fixing the fitting pins 31 a and 32 a to the game board 530.

  Further, since the relief portions 535a wider than the receiving portion 532c are formed on the left and right of the reinforcing rib 535 (see FIG. 31A), the protruding portions 32a formed in the inner rail portion 32 are stacked. Interference with the reinforcing rib 535 of the game board 530 can be prevented. Further, the clearances 535a (see FIG. 31 (b)) have the height from the board surface 530a set lower than the receiving portions 532c, so the height of the protruding portions 32a (the vertical direction in FIG. 31 (a)). Can be prevented from interfering with the relief portion 535a of the stacked game board 530 even when the value is set to a value larger than the height of the inner rail portion 32. This makes it possible to prevent the bending portion 32a from producing an adverse effect such as plastic deformation of the overhanging portion 32a and a change in shape while the plurality of game boards 530 are stacked and waiting.

  Further, since the height of the outer peripheral rail receivers 531 c and 531 d in the thickness direction of the game board 530 is set to a value smaller than that of the outer peripheral reinforcing rib 531, the outer peripheral reinforcing rib 531 is formed on the flat surface G. When the game board 530 is placed downward, a gap is created between the flat surface G and the game board 530 by the amount of the outer peripheral rail receivers 531 c and 531 d. A fingertip or the like of a hand can be inserted into the gap, and the gaming board 530 placed on the flat surface G can be lifted using the inserted fingertip or the like as a clue.

  On the other hand, when the heights of the outer peripheral rail receivers 531 c and 531 d in the thickness direction of the game board 530 are set to a value larger than the height of the outer peripheral reinforcing rib 531, A rattling occurs on the set game board 530. The game board 530 can solve this problem, and the outer peripheral reinforcing rib 531 faces downward, and the play of the game board 530 placed flat on the flat surface G can be prevented, and the game board can be stably set. Furthermore, when lifting the game board 530 placed flat, it is possible to use the fingertips inserted in the outer peripheral rail receivers 531 c and 531 d as a clue, and the handling of the game board 530 in the middle of manufacturing and the completed game board 530 It can improve.

  Further, the heights of the outer peripheral rail receivers 531 c and 531 d in the thickness direction of the game board 530 are set to the same values as the rail receivers 532, 533 and 534 (receivers 532 c, 533 a and 534 c), When a plurality of game boards are stacked so that the back surface of the game board 530 and the board surface 530a of another game board 530 face each other, the board surfaces 530a of the plurality of game boards 530 can be substantially parallel. As a result, the plurality of game boards 530 can be stacked substantially vertically, and it is possible to make it difficult for the stacked game boards 530 to slide down. Furthermore, the outer rail portion 31 of the game board 530 is prevented from interfering with the outer peripheral rail receivers 531 c and 531 d of the stacked game board 530. As a result, it is possible to prevent an adverse effect such as deformation of the outer rail portion 31 while the plurality of game boards 530 are stacked and waiting.

  In addition, when a plurality of game boards 530 are stacked, the outer rail portion 31 is provided with a projection (rail receiver) 69a provided on another game board 530, a rail receiver 533 (provided upright on the thin portion 72), a rail It abuts on the receivers 532 and 534 and the outer peripheral rail receivers 531 c and 531 d. On the other hand, the inner rail portion 32 abuts on a rail receiver 532 (provided erect on the inclined surface portion 71) provided on another game board 530.

  Here, the gaming balls fired from the gaming ball launching device 21 move along the outer rail portion 31 by centrifugal force and are guided to the gaming area PE. Therefore, the curvature or the like of the outer rail portion 31 affects the trajectory of the game ball driven into the game area PE. On the other hand, since the inner rail portion 32 is disposed on the inner side of the outer rail portion 31, the influence of the curvature or the like of the inner rail portion 32 on the trajectory of the gaming ball is smaller than that of the outer rail portion 31. When the game boards 530 are stacked, the game board 530 is supported by the rail receivers 532 and the like coming into contact with the inner rail portion 32 and the outer rails 31, so the load of the stacked game boards 530 is the outer rail portion 31. Concentrated loads are prevented. That is, by dispersing the load applied to the outer rail portion 31 to the inner rail portion 32, the load applied to the outer rail portion 31 can be reduced. Thus, plastic deformation of the outer rail portion 31 can be prevented by stacking the game boards 530. Thus, the trajectory of the game ball driven into the game area PE can be stabilized.

  Further, the contact area between each of the rail receivers 534 and the outer peripheral rail receivers 531 c and 531 d and the outer rail portion 31 is larger than the contact area between each of the rail receivers 532 and 533 and the inner rail portion 32. Therefore, the load per unit area applied to the outer rail portion 31 can be reduced by the rail receivers 534 and the outer peripheral rail receivers 531 c and 531 d. As a result, plastic deformation of the outer rail portion 31 due to the load of the stacked game boards 530 can be suppressed.

  Here, in the outer rail portion 31, the portion facing the inner rail portion 32 (left side in FIG. 24) has a great influence on the trajectory of the game ball hit from the game ball launch device 21 into the game area PE. This is because the gaming ball moves along the outer rail portion 31 opposed to the inner rail portion 32 by centrifugal force. On the other hand, the area U (see FIG. 24) of the outer rail portion 31 located to the right of the reference hole 534a when the gaming board 530 is viewed from the front has a relatively small influence on the trajectory of the gaming ball driven into the gaming area PE. . This is because the trajectory of the gaming ball moving along the area U is restricted not only by the outer rail portion 31 but also by the shape and arrangement of the surface components such as the center frame 47 and the like.

  Therefore, when stacking the plurality of game boards 530, the heights of the rail receivers 532 and 534 are such that the rail receivers 532 and 534 located in the area U of the outer rail unit 31 and in the vicinity thereof abut the outer rail unit 31. It is effective to set Even if the outer rail portion 31 (area U) is plastically deformed by the load of the stacked game board 530, it has little influence on the trajectory of the game ball.

  In this case, in the outer rail portion 31, only the area U is in contact with the rail receiver 532 of the other game board 530, and the region other than the area U is noncontact with the rail receiver 532 of the other game board 530 or the like. The height of the receiver 532 is set. The inner rail portion 32 sets the height of the rail receiver 532 or the like so as to abut on the rail receiver 532 or the like of another game board 530. As a result, when the area U of the outer rail portion 31 and the inner rail portion 32 abut on the rail receivers 532 and the like of the other game boards 530, the plurality of game boards 530 are stacked. Thereby, in the outer rail portion 31, the load of the stacked game board 530 is applied to a part (a part other than the area U) which greatly affects the trajectory of the game ball hit from the game ball launch device 21 to the game area PE. Can be prevented. As a result, it is possible to prevent a portion (a portion other than the area U) which greatly affects the trajectory of the gaming ball driven into the game area PE from being adversely affected by the load of the stacked game boards 530.

  Also, in addition to the rail receptacles 532 disposed in the area U of the outer rail portion 31, a rail receptacle 534 (see FIG. 26) disposed in the vicinity of the area U of the outer rail portion 31 is used. It is possible to support the outer rail portion 31. The rail receiver 534 is provided in the reference hole 534a, and the area of the receiver 534c (FIG. 30) can be secured. Therefore, when supporting the outer rail portion 31, compared to the case where the rail receiver 534 is not used. Thus, the load acting on the unit area of the outer rail portion 31 can be reduced. Thereby, compared with the case where the rail receptacle 534 is not used, it can be hard to have a bad influence on the area | region U of the outer rail part 31 by the load of the accumulated game board 530. FIG.

  In the present embodiment, the area U of the outer rail portion 31 abuts the rail receiver 532 of the other game board 530, and the portion (outer rail portion 31) other than the area U is the rail receiver 532 of the other game board 530. Although the case of setting the height of the rail receiver 532 or the like to be noncontact with the etc. has been described, the area U of the outer rail portion 31 is also noncontact with the rail receiver 532 of another game board 530 It is of course possible to set the height of the receptacle 532. Thus, the load of the stacked game boards 530 can be prevented from being applied to the outer rail portion 31, and thus the outer rail portion 31 can be prevented from being adversely affected by the load of the stacked game boards 530. Since the game board 530 is supported by the inner rail portion 32 and the rail receiver 532 which hardly affect the trajectory of the game ball, the trajectory of the game ball can be stabilized even if the inner rail portion 32 is plastically deformed. .

  Next, another embodiment is described with reference to FIG. In the sixth embodiment, the case where the game board 530 is placed on the outer rail portion 31 and the inner rail portion 32 by the outer peripheral rail receiver 531 d and the rail receiver 532 has been described. On the other hand, in another embodiment shown in FIG. 33 (b), the case where the game board 560 is placed on the outer rail portion 31 and the passage forming member 538 by the outer peripheral rail receivers 531d and 531f will be described. The same parts as those described in the sixth embodiment are assigned the same reference numerals and explanation thereof will be omitted. FIG. 33 (b) is a cutting section end view schematically showing a state in which a plurality of gaming boards 560 in another embodiment are stacked.

  As shown in FIG. 33 (b), in the state where the gaming board 560 is mounted on the pachinko machine 1 (see FIG. 2), the outer rail portion 31 protrudes on the left outer edge when the gaming board 560 is viewed from the front. The passage forming member 538 (a kind of rail member) is disposed in the vicinity of the outer peripheral edge on the right side of the board. The passage forming member 538 is a member made of a synthetic resin continuously connected to the inner rail portion 32 to partition the game area PE, and is fixed on the right side of the board of the game board 560 with a screw or the like. The height from the surface of the passage forming member 538 is set to be substantially the same as the height from the surface of the outer rail portion 31 and the inner rail portion 32.

  The outer peripheral edge reinforcing rib 531 (right side when viewed from the game board 560) located at a position facing the outer peripheral edge reinforcing rib 531 (left from the front view of the game board 560) where the outer edge rail receiver 531d is formed is An outer peripheral rail receiver 531 f is formed on the rear end surface. The outer peripheral rail receiver 531 f is a portion for receiving the passage forming member 538 fixed to the other game board 560 when the plurality of game boards 560 are stacked, and the height from the board is the outer peripheral rail It is set to the same value as the receiving 531 d.

  The game board 560 has a hole 68 which is formed to penetrate in the thickness direction, and a protrusion 537 is provided around the hole 68. The axial length (the vertical direction in FIG. 33B) of the protrusion 537 is set to a value shorter than the axial length of the rail receiver 532 (see FIG. 33A). Therefore, when the plurality of game boards 530 are stacked, the side edge (upper end) of the inner rail portion 32 provided on the game board 560 and the projecting part 537 are in a non-contact state. Therefore, the game board 560 is placed and stacked on the outer rail portion 31 and the passage forming member 538 by the outer peripheral rail receivers 531 d and 531 f. Since the outer peripheral rail receivers 531 d and 531 f are provided on the outer peripheral reinforcing rib 531, even if the outer rail portion 31 and the passage forming member 538 are arranged so as to project over the outer peripheral edge of the game board 560, the game board 560 Can be prevented from interfering with the outer rail portion 31 and the passage forming member 538 and the outer peripheral reinforcing rib 531. Thereby, the game area PE of the game board 560 can be greatly expanded.

  Referring now to FIG. 34, another embodiment of the rail receptacle 532 will be described. In the sixth embodiment, the case where the protrusions 532a and 532b, which are opposed to each other, project from the receiving portion 532c formed on the axial end surface of the rail receiver 532 has been described. On the other hand, in FIG. 34, the case where one of the protrusions 532a and 532b is provided in the receiving portion 532c will be described. The same parts as those in the sixth embodiment are given the same reference numerals, and the description thereof will be omitted. FIGS. 34 (a) and 34 (b) are cutting end views schematically showing a state in which a plurality of gaming boards 570, 580 according to another embodiment are stacked.

  As shown in FIG. 34 (a), each rail receiver 542 is provided with a protrusion 532b located on the thick portion 70 side (the center side of the game board). Since the projection 532b (the receiving surface 532b1) faces the outer rail portion 31 and the inner rail portion 32, positional deviation of the stacked game boards 570 can be prevented, and sliding of the game boards 570 can be prevented.

  Further, as shown in FIG. 34 (b), each rail receiver 543 is provided with a protrusion 532a located on the outer peripheral edge reinforcing rib 531 side (the outer peripheral side of the game board). Since the projection 532a (the receiving surface 532a1) faces the outer rail portion 31 and the inner rail portion 32, positional deviation of the stacked game boards 580 can be prevented, and sliding of the game boards 580 can be prevented.

  Next, referring to FIG. 35 and FIG. 36, the guide portion reinforcing member 550 fixed to the board surface 530a of the game board 530 will be described. The guide portion reinforcing member 550 is a member for reinforcing the outer rail portion 31. In the first embodiment, the inclined portion 52a coupled to the contact portion 52b of the guide portion reinforcing member 50 is formed to have substantially the same width with respect to the distance separating from the fitting convex portion 55 when viewed from the front. Case was explained. On the other hand, in the present embodiment, the case where the inclined portion 553 is formed so as to increase in width in a front view as being away from the fitting convex portion 55 will be described. The same parts as those described in the first embodiment are given the same reference numerals, and the description thereof will be omitted. FIG. 35 (a) is a partially enlarged front view of the game board 530 to which the guide portion (outer rail portion 31) and the guide portion reinforcing member 550 are fixed, and FIG. 35 (b) is a line XXXVb-XXXVb in FIG. FIG. 16 is an end view of the guide (the outer rail 31) and the cut portion of the guide reinforcing member 550 in FIG.

  As shown in FIGS. 35 (a) and 35 (b), the guide portion reinforcing member 550 is formed into a substantially trapezoidal shape in a front view (as viewed from the board side of the game board 530) and the outer rail portion 31. Body 51 located on the opposite surface side of the guide surface 31c, the opposite surface side projecting portion 551 erected on the substrate portion 51, and the direction opposite to the direction in which the opposite surface side projecting portion 551 is erected It is mainly provided with the fitting convex part 55 protrudingly provided from the base | substrate part 51 in direction. The guide portion reinforcing member 550 is a member made of synthetic resin.

  The opposite surface side projecting portion 551 is connected to a contact portion 552 which contacts at least a part of the opposite surface of the outer rail portion 31 while facing the opposite surface of the outer rail portion 31, and the contact portion 552 And an inclined portion 553 which is inclined downward toward the axial direction of the fitting protrusion 55 from the top. The inclined portion 553 is provided so as to be offset with respect to the fitting convex portion 55 radially outward with the fitting convex portion 55 as a rotation center. Furthermore, the inclined portion 553 is formed such that the distance from the contact portion 552 increases in a front view as the distance from the fitting convex portion 55 increases. In other words, the sloped portion 553 is formed such that the width in the front view increases as the distance from the fitting convex portion 55 increases.

  Next, with reference to FIG. 36, a method of attaching the guide portion reinforcing member 550 and the outer rail portion 31 to the game board 530 will be described. FIG. 36 (a) is a partially enlarged front view of the game board 530 showing a state in which the guide portion reinforcing member 550 is fixed, and FIG. 36 (b) is a portion in which the guide portion (outer rail portion 31) and the guide portion reinforcing member 550 are fixed. 3 is a partially enlarged front view of the game board 530 showing a state of playing. In FIG. 36 (a), the position of the outer rail portion 31 disposed on the game board 530 is shown by a two-dot chain line.

  As shown in FIG. 36 (a), in the case where the guide portion reinforcing member 550 and the outer rail portion 31 are disposed on the board surface 530a of the game board 530, the fitting convex portion 55 of the guide portion reinforcing member 550 is A half of the length is inserted into the hole 69 of the disc 530 and temporarily arranged. At the time of temporary arrangement, the position of the inclined portion 553 is made to overlap the position (two-dot chain line) where the outer rail portion 31 is arranged in a front view.

  Next, as shown in FIG. 36 (b), in order to dispose the outer rail portion 31, the side edge of the outer rail portion 31 (the rear side edge in the paper surface of FIG. 36 (b)) Get closer. Since the inclined portion 553 is provided so as to be offset radially outward with respect to the fitting convex portion 55 which is the rotation center with respect to the hole 69, as the outer rail portion 31 approaches the board surface 530a, The inclined portion 553 is pushed by the outer rail portion 31, and the guide portion reinforcing member 550 rotates around the fitting convex portion 55. When the side edge of the outer rail portion 31 (the back side edge in FIG. 36B) leaves the inclined portion 553, the pivoting of the guide portion reinforcing member 550 is stopped and the position of the guide portion reinforcing member 550 is determined.

  Furthermore, when the outer rail portion 31 is brought close to the board surface 530a, the outer rail portion 31 is accommodated in the groove portion 58 between the contact portion 552 and the guide surface side protruding portion 57. When the outer rail portion 31 is further brought close to the board surface 530a in that state, the base end side end face (bottom surface of the groove portion 58) of the fitting convex portion 55 is pushed to the side edge of the outer rail portion 31. The holes 69 are gradually inserted. Thereby, the workability of the arrangement operation of arranging the outer rail portion 31 to the board surface 530 a of the game board 530 can be improved.

  As described above, the inclined portion 553 provided to be offset radially outward with respect to the fitting convex portion 55 serving as the center of rotation causes the force to cause the outer rail portion 31 to approach the board surface 530a. It can be converted to a force for pivoting the guide portion reinforcing member 550 around 55. As a result, before the outer rail portion 31 is disposed, in the work of inserting the fitting convex portion 55 of the guide portion reinforcing member 550 into the hole portion 69 of the game board 530 and temporarily arranging, the position of the inclined portion 553 is the outer rail It may be made to overlap with the position where the portion 31 is disposed. Therefore, it is possible to hardly require the accuracy of the position alignment (angle alignment of the contact portion 552 with the fitting convex portion 55 which is the rotation center) in the temporarily arranging operation. As a result, the outer rail portion 31 and the guide portion reinforcing member 550 can be smoothly arranged on the board surface 530a of the game board 530, and the workability of the arranging operation can be improved.

  Further, the inclined portion 553 is formed such that the distance from the contact portion 552 increases in a front view as the distance from the fitting convex portion 55 increases. That is, in the front view, the sloped portion 553 is formed to have a narrow width on the side of the fitting convex portion 55, and is formed so as to widen as it is separated from the fitting convex portion 55. Thereby, the position alignment in the operation of temporarily arranging the guide portion reinforcing member 550 on the game board 530 by an amount that can increase the width of the inclined portion 553 on the opposite side to the fitting convex portion 55 The accuracy of the angular alignment of the contact portion 552 with respect to 55 can be reduced. As a result, the time required for alignment of the operation of temporarily arranging the guide portion reinforcing member 550 on the game board 530 can be shortened, and the operation of arranging the outer rail portion 31 and the guide portion reinforcing member 550 can be streamlined.

  In each of the above-described embodiments, a part or a plurality of parts of the configuration of the other embodiment are added to the embodiment or replaced with a part or the plurality of parts of the configuration of the embodiment. The embodiment may be modified.

  Hereinafter, in addition to the gaming machine of the present invention, the concept of various inventions included in the above embodiment will be shown.

  A game ball launch device for firing a game ball, a synthetic resin game board forming a game area in which a game ball fired by the game ball launch device flows, and the game ball launch disposed on the board surface of the game board In a gaming machine comprising: a strip-like guiding portion for guiding a game ball fired by a device to the playing area along a guiding surface, the gaming machine further comprising a guiding portion reinforcing member fixed to the board surface of the gaming board The member is provided with a fitting convex portion fitted in a hole formed in a depression on the surface of the game board, and the convex portion is in contact with the side opposite to the guiding surface of the guiding portion A game machine A1 characterized by comprising an opposite surface side projecting portion.

  According to the gaming machine A1, the gaming area in which the gaming balls fired by the gaming ball launching device flow down is formed by the gaming board made of synthetic resin. On the board surface of the gaming board, a band-like guide portion is arranged for guiding the game balls fired by the game ball launching device to the game area along the guide surface. The guide reinforcing member is fixed to the board surface of the game board. In the guiding part reinforcing member, the fitting convex part is fitted in the hole formed in the recess shape on the board surface of the game board, and the opposite surface side protruding part protruding from the fitting convex part guides the guiding part Contact the opposite side of the surface. As a result, it is possible to prevent the guide surface from being pushed to the opposite side by the gaming ball advancing toward the game area along the guide surface and tilting of the strip-shaped guide portion. Since the tilting of the guiding portion for guiding the gaming balls to the gaming area can be suppressed, there is an effect that the trajectory and the flying distance of the gaming balls guided to the gaming area can be stabilized.

  That is, when the guide surface is pushed to the opposite side by the game ball advancing toward the game area along the guide surface and the belt-like guide portion tilts, the trajectory of the game ball changes or the motion energy loss of the game ball Will occur. As a result, the trajectory and flight distance of the gaming ball guided to the gaming area may be unstable.

  On the other hand, according to the gaming machine A1, by arranging the guide portion reinforcing member so that the opposite surface side protruding portion is in contact with the side opposite to the guide surface of the guide portion, It is possible to suppress the tilting of the guiding portion by the game ball advancing toward. This makes it possible to stabilize the trajectory and flight distance of the game ball guided to the game area.

  In the gaming machine A1, a gaming machine A2 characterized in that the fitting convex portion is provided with a recess in which a part of the outer peripheral surface is formed in a recess.

  According to the gaming machine A2, the recess is formed in a part of the outer peripheral surface of the fitting convex portion, and therefore, the outer peripheral surface of the fitting convex portion when the fitting convex portion is fitted in the hole The contact area with the inner peripheral surface of the hole can be reduced. As a result, it is possible to increase the vertical effectiveness per unit area of the hole and the fitting protrusion when the fitting protrusion is fitted in the hole. Thus, when the fitting convex portion is fitted in the hole, the hole or the fitting convex portion can be easily deformed (elastically or plastically deformed), so that the fitting in addition to the effects of the gaming machine A1 can be achieved. The joint convex portion can be easily fitted in the hole.

  In the gaming machine A1 or A2, the recessed portion is formed in a scraped shape from a tip end of the fitting convex portion toward a base end.

  According to the gaming machine A3, since the concave portion is formed in the form of a slip toward the proximal end from the tip of the fitting projection, the hole is fitted using the elastic deformation of the fitting projection due to the rubbing. The fitting convex portion can be fitted. As a result, in addition to the effects of the gaming machine A1 or A2, the fitting convex portion can be easily fitted into the hole, and by utilizing the elastic deformation of the fitting convex portion, the hole and the fitting convex portion can be obtained. Since generation of a gap can be prevented, it is possible to make the fitting convex portion fitted in the hole portion less likely to rattle.

In this case, it is possible to make the upper game board load applied to the stacked lower game board nails zero. In addition, when the nail implanted on the board of another game board contacts the back of the game board, the load of the upper game board applied to the nails of the stacked lower game board can be determined by the rail support and the outer edge. It can be made smaller by distributing it to the rail holder. Thus, in addition to the effects of any one of the game boards D1 to D3, when the game boards are stacked, it is possible to prevent an adverse effect such as bending of a nail planted on the game board.

  In the gaming machine D4, the height of the rail receptacle in the thickness direction of the gaming board is set to the same value as that of the outer peripheral rail receptacle.

According to the gaming machine D5, the height of the rail receptacle in the thickness direction of the gaming board is set to the same value as the height of the outer peripheral rail receptacle in the thickness direction of the gaming board. When the game board and the other game board are stacked such that the board of the other game board faces the other, the board of the game board and the board of the game board of the other game board can be substantially parallel. As a result, in addition to the effects of the gaming machine D4, the game boards can be stacked substantially vertically, and it is possible to make it difficult for the stacked game boards to slide down.

In this type of gaming machine, conventional gaming boards are generally produced by sticking a synthetic resin film on which a pattern has been printed on the surface of a wooden plywood (veneer). In recent years, a game board made of synthetic resin is being adopted from the viewpoint of designability and recyclability (for example, JP-A-10-113428 (in particular, FIG. 5)).
In such pachinko machines, it is common to detachably attach the game board to the pachinko machine main body and to make it possible to replace the game board with the pachinko machine main body if necessary, such as model change. Therefore, in general, the game board is produced through a manufacturing process that is separate from the pachinko machine main body. In the manufacturing process of the synthetic resin game board, first, a nail (obstacle nail) is planted on a synthetic resin game board plate. Then, after attaching small parts, such as a windmill, and a rail member (induction rail) to a plate material, large parts, such as a large winning device and a control circuit board, are assembled. In assembling large parts, the process becomes complicated because the work becomes complicated. Due to the imbalance of the process capability, the game board in the process of manufacture may temporarily stagnate between processes. In such a case, the game boards in the process of manufacture may be temporarily stacked in order to make the stagnated game boards stand by.
