It is integrally molded with a peripheral edge reinforcing rib 73 erected in the above.

Next, the cross-sectional shape of the game board 30 will be described with reference to FIG. FIG. 8 is an end view of the cut portion of the game board 30 on the line VIII-VIII of FIG. As shown in FIG. 8, the game board 30 is formed on the board surface side (front side, lower side in FIG. 8) as a flat surface, and the wall thickness portion 70 is formed on the back surface side (upper side in FIG. 8) to have a plate thickness. It is set to be almost constant. The inclined surface portion 71 is connected to the wall thickness portion 70 and is formed so that the plate thickness gradually decreases as it approaches the peripheral edge of the game board 30 (toward the outer periphery). The thin portion 72 is continuously provided around the inclined surface portion 71 and is set to a plate thickness smaller than the plate thickness of the thick portion 70. The outer peripheral edge reinforcing rib 73 is a portion for improving the rigidity of the thin portion 72, and is continuously provided around the thin portion 72 and projects from the outer peripheral edge of the thin portion 72 to the back surface side. Since the height of the outer peripheral edge reinforcing rib 73 (vertical direction in FIG. 8) is set to a value larger than the thickness of the wall thickness portion 70, the game board 30 is outside to be mounted on the resin base 20 of the main body frame 3. It is possible to prevent the thick portion 70 from interfering with the resin base 20 when the back surface side end portion of the peripheral edge reinforcing rib 73 is brought into contact with the front surface of the resin base 20.

It will be described back to FIG. The wall thickness portion 70 is located at a substantially central portion on the back surface side of the game board 30, and a game region PE is formed on the front surface side of the wall thickness portion 70. Since nails that interfere with the game ball are planted in the game area PE, a wall thickness 70 is formed in the substantially central portion of the game board 30 on which the game area PE is formed to secure the plate thickness. The holding power of the nail to be planted in the portion 70 can be secured.

Further, since the plate thickness of the wall thickness portion 70 of the game board 30 is set to be smaller than the height of the outer peripheral edge reinforcing rib 73, the game board 30 has a uniform thickness with the height of the outer peripheral edge reinforcing rib 73 as the plate thickness. It can be lighter than the board. Since a space can be provided on the back side of the thick portion 70 by the amount that the plate thickness of the thick portion 70 is set smaller than the height of the outer peripheral edge reinforcing rib 73, decorations and the like are arranged in the space on the back side. It becomes possible to do. Since it is possible to arrange a light emitting element such as an LED in the space on the back side thereof, it is possible to improve the effect of the effect.

Further, since a thin portion 72 having a thickness smaller than that of the thick portion 70 is formed between the thick portion 70 and the outer peripheral edge reinforcing rib 73, the thickness of the thick portion 70 and the thickness of the thin portion 72 are formed. The amount of synthetic resin can be reduced by the difference from. As a result, the game board 30 can be further reduced in weight. Further, since a space can be provided on the back side of the thin portion 72 by the amount that the plate thickness of the thin portion 72 is set smaller than the height of the outer peripheral edge reinforcing rib 73, decorations and the like are arranged in the space on the back side. It becomes possible. Since it is possible to arrange a light emitting element such as an LED in the space on the back side thereof, it is possible to improve the effect of the effect.

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. As a result, the flatness of the board surface of the game board 30 can be ensured.

An inclined surface portion 71 is formed on the outer periphery of the thick portion 70. The inclined surface portion 71 is set so that the thickness gradually decreases from the thick portion 70 toward the outside, and is coupled to the thin portion 72. As a result, it is possible to prevent deformation due to the difference in thickness between the thick portion 70 and the thin portion 72 during molding of the game board 30. That is, the game board 30 is molded by melting and filling the cavity of the molding die with a synthetic resin, 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 thin portion 72 having a small thickness than in the thick portion 70 having a large thickness, residual stress is generated due to the difference in the cooling rate, and the game board 30 is likely to be deformed such as warped. However, the inclined surface portion 71 coupled between the thin portion 72 and the thick portion 70 can buffer the generation of residual stress due to the difference in the cooling rate. As a result, the game board 30 can be less likely to be deformed such as warped.

The hole 68 formed at the boundary between the thick portion 70 and the inclined surface portion 71 is a portion where a spot-welded fitting pin (described later) is inserted into the inner rail portion 32. The holes 68 formed in the thin portion 72 and the peripheral edge reinforcing rib 73, which are located on the outer peripheral edge side of the game board 30 from the boundary between the thick portion 70 and the inclined surface portion 71, are spot-welded to the outer rail portion 31. This is the part where the matching pin (described later) is inserted. The hole portion 68 is continuously provided with a cylindrical protruding portion 68a that rises from the periphery of the hole portion 68 toward the back surface side. The hole 68 penetrates the game board 30 in the thickness direction.

Since the protrusion 68a is formed around the hole 68, the plate thickness around the hole 68 can be increased. As a result, the load per unit area applied by the fitting pin to the inner circumference of the hole 68 can be reduced, so that cracks are less likely to occur around the hole 68 (particularly the thin portion 72). Further, since the depth of the hole 68 (in the front-rear direction of the game board 30) can be increased by the protruding portion 68a, the holding force of the fitting pin can be increased. As a result, the outer rail portion 31 and the inner rail portion 32 can be firmly fixed to the board surface of the game board 30.

Further, the protruding portion 68a (hole portion 68) into which the fitting pin spot-welded to the inner rail portion 32 is inserted is formed at the boundary between the thick portion 70 and the inclined surface portion 71, and the thickness is formed on the outer periphery of the protruding portion 68a. The portion 70 and the inclined surface portion 71 are connected 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 protruding length of the protruding portion 68a with respect to the thick portion 70 and the inclined surface portion 71 is set from the protruding length of the protruding portion 68a with respect to the thin portion 72. Can be made smaller. As a result, the bending moment of the protruding portion 68a with respect to the thick portion 70 and the inclined surface portion 71 can be made smaller than the bending moment of the protruding portion 68a with respect to the thin portion 72, so that the protruding portion protruding from the thick portion 70 and the inclined surface portion 71 can be made smaller. The bending strength of 68a can be improved from the bending strength of the protruding portion 68a projecting from the thin portion 72.

In addition, a fitting pin spot-welded to the inner rail portion 32 is fitted into the hole portion 68 formed in the protruding portion 68a formed at the boundary between the thick portion 70 and the inclined surface portion 71. By providing the thick portion 70 inside the inner rail portion 32 in which the game area PE is formed, it is possible to secure the holding force of nails, wind turbines, and the like. The area of the thick portion 70 is excessive by providing a protruding portion 68a (hole portion 68) into which a spot-welded fitting pin is fitted into the inner rail portion 32 at the boundary between the thick portion 70 and the inclined surface portion 71. Can be prevented from increasing to. By preventing the thick portion 70 from expanding outside the region where the game region PE is formed (inside the inner rail portion 32), 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 at the lower position of the game board 30 and the inclined surface portion 71, and penetrates in the thickness direction of the game board 30. Reinforcing ribs 39a are erected around the out port 39 toward the back surface side, and the reinforcing ribs 39a are integrally formed with the game board 30. The reinforcing rib 39a constitutes a passage for the game ball that has entered the out port 39 from the game area PE, and can reinforce the periphery of the out port 39 to improve the rigidity.

The hole portion 69 is a portion into which the fitting convex portion 55 (described later) of the guide portion reinforcing member 50 is fitted, and is formed through the thin portion 72. Since the protrusion 69a 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 circumference of the hole portion 69 can be reduced, so that cracks can be less likely to occur around the hole portion 69 (thin portion 72). Further, since the depth of the hole 69 (in the front-rear direction of the game board 30) can be increased by the protruding portion 69a, the holding force of the fitting convex portion 55 can be increased. As a result, the guide portion reinforcing member 50 can be firmly fixed to the board surface of the game board 30.

The outer peripheral edge reinforcing rib 73 is formed with recesses 73a, 73b, 73c in which a part of the end surface on the back surface side (front side of the paper surface in FIG. 7) is recessed in the height direction (the height of the rib is lowered). .. The recessed portions 73a and 73c are formed at positions facing the outer peripheral edge reinforcing ribs 73 (left and right ribs), and the recessed portion 73b intersects with the outer peripheral edge reinforcing ribs 73 (left and right ribs) on which the recessed portions 73a and 73c are formed. It is formed on the outer peripheral edge reinforcing rib 73 (lower rib). Since the recesses 73a and 73c are formed at the positions facing the outer peripheral edge reinforcing ribs 73, the molded game board 30 is placed with the outer peripheral edge reinforcing ribs 73 facing downward on a table having a flat surface formed on the upper surface. When placed (with the back side facing down), a gap is formed between the flat surface and the game board 30 (outer peripheral edge reinforcing rib 73) by the amount of the recesses 73a and 73c. The fingertips of the hand or the like are inserted into the gap, and the game board 30 placed on the flat surface can be lifted by using the inserted fingertips or the like as clues.

On the other hand, when the recessed portions 73a, 73b, 73c are not formed on the end surface of the outer peripheral edge reinforcing rib 73 on the back surface side, the outer peripheral edge reinforcing rib 73 is placed on a table having a flat surface formed on the upper surface. When the game board 30 is placed toward the surface (with the back surface facing downward), the entire circumference of the end surface of the outer peripheral edge reinforcing rib 73 on the back surface side is in close contact with the flat surface (no gap is formed). In that case, since it is difficult to insert the fingertips of the hand or the like between the outer peripheral edge reinforcing rib 73 and the flat surface (table), 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 73a, 73b, 73c in the outer peripheral edge reinforcing rib 73.

The openings 62 are through holes to which the protruding pins 60 are attached, and are formed at two diagonal positions of the game board 30. Reinforcing ribs 62a are erected around the opening 62 toward the back surface side, and the reinforcing ribs 62a are coupled to the outer peripheral wall reinforcing ribs 62a.

The heights of the reinforcing ribs 39a and 62a and the protruding portions 68a and 69a are set to be substantially the same as the height of the peripheral portion reinforcing ribs 73. As a result, the board surface of the game board 30 (with the back side facing down) is placed on the table on which the flat surface is formed on the upper surface with the outer peripheral edge reinforcing ribs 73 facing down. When a load is applied to the front surface), the load can be received by the reinforcing ribs 39a, 62a, the protruding portions 68a, 69a, and the peripheral portion reinforcing rib 73.

On the other hand, when the reinforcing ribs 39a and 62a and the protruding portions 68a and 69a are not formed, when the game board 30 receives a load on the board surface, the thick portion 70 and the thin portion 72 are bent and deformed. When the deformation becomes large, the vicinity of the boundary between the peripheral edge reinforcing rib 73 and the thin portion 72 may be cracked. According to the present embodiment, by setting the heights of the reinforcing ribs 39a and 62a and the protruding portions 68a and 69a to be substantially the same as the height of the peripheral portion reinforcing ribs 73, the wall thickness portion 70 and the wall thickness are thin due to the load applied to the board surface. Since it is possible to suppress bending deformation of the portion 72, this problem can be solved.

In particular, the protruding portions 68a for fixing the outer rail portion 31 and the inner rail portion 32 are located on a substantially semicircular annular line and are widely scattered on the game board 30, so that a specific location on the board surface of the game board 30 is specified. Even when a concentrated load is applied to the game board 30, it is possible to prevent a large bending deformation from occurring on the board surface 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 parts are attached.

Next, the opening 62 and the protruding pin 60 will be described with reference to FIG. FIG. 9 is an end view of the cut portion of the game board 30 in the IX-IX line of FIG. As shown in FIG. 9, the projecting pin 60 is a substantially columnar member formed of a member different from the game board 30, and includes a flange portion 60a projecting from the outer peripheral surface in the radial direction (horizontal direction in FIG. 9). An insertion / insertion portion 60b extending from the flange portion 60a to the other side in the axial direction is continuously provided. The fitting portion 60b is a portion to be fitted into the opening 62, and the flange portion 60a is a portion for regulating the insertion depth of the fitting portion 60b to be fitted into the opening 62. On the other hand, a recessed portion 62b for receiving the collar portion 60a is formed on the surface of the game board 30. The recessed portion 62b is continuously provided around the opening 62 at a depth substantially equal to the thickness of the flange portion 60a. The diameter of the protruding pin 60 is formed to be slightly smaller than the diameter of the fitting portion 60b (inner diameter of the opening 62).

The end surface of the reinforcing rib 62a on the back surface side (lower side in FIG. 9) is set at a height position substantially the same as the end surface on the back surface side (lower side in FIG. 9) of the peripheral edge reinforcing rib 73. As a result, the depth of the opening 62 (vertical direction in FIG. 9) can be increased, so that the insertion depth at which the fitting portion 60b is fitted into the opening 62 can be increased. On the other hand, when the reinforcing rib 62a is not formed, the depth of the opening 62 is the same as the plate thickness of the thin portion 72. In that case, as compared with the present embodiment, the holding force for holding the fitting portion 60b in the opening 62 becomes smaller, and the protruding pin 60 tends to rattle or come off. By providing the reinforcing rib 62a as in the present embodiment, it can be prevented.

Further, since the game board 30 in which the fitting / inserting portion 60b is fitted into the opening 62 has a flange portion 60a, the protruding pin 60 projects from the board surface of the game board 30 by a predetermined length. On the other hand, the reinforcing rib 62a is set so that a recess (hole) deeper than the protrusion length from the board surface of the protrusion pin 60 is formed on the back surface side (lower side in FIG. 9). Since the diameter of the protruding pin 60 is formed to be slightly smaller than the diameter of the fitting portion 60b (inner diameter of the opening 62), when a plurality of game boards 30 are stacked, the board surface of one game board 30 can be used. The protruding protruding pin 60 is inserted into the recess (hole) in the reinforcing rib 62a from the back surface side of the other game board 30. As a result, it is possible to prevent the game boards 30 stacked in a flat state from being displaced in the board surface direction.

By configuring the protruding pin 60 as a separate member from the game board 30 as in the present embodiment, the game board is formed after the game board 30 is formed until the protruding pin 60 is fitted into the opening 62. The protruding pin 60 can be prevented from protruding from the board surface of the 30. As a result, it is possible to prevent the protruding pin 60 from hindering the transportation of the game board 30 or damaging the protruding pin 60 until the protruding pin 60 is fitted into the opening 62 after molding the game board 30. it can. Further, if the protruding pin 60 is no longer needed when assembling the pachinko machine 1 after fitting the protruding pin 60 into the opening 62, the protruding pin 60 can be pulled out from the opening 62. As a result, the pachinko machine 1 can be assembled smoothly.

It is also possible to form the protruding pin 60 integrally with the game board 30 at the time of molding the game board 30. When the protruding pin 60 is fitted (inserted) into the game board 30 as in the present embodiment, it is necessary to prepare the protruding pin 60 as a separate member and insert the protruding pin 60 into the game board 30. On the other hand, by forming the protruding pin integrally with the game board, it is not necessary to prepare the protruding pin 60 as a separate member, so that the number of parts can be reduced. Further, the work of inserting the protruding pin 60 into the game board 30 can be eliminated.

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 melt-filling a molding die with synthetic resin, and an outer peripheral edge reinforcing rib 73 is erected on the back side of a flat board surface (front surface). When the synthetic resin game board 30 is stacked and transported, there is a problem that the position of the synthetic resin game board 30 is displaced and the game board is easily slipped off as compared with the case where the conventional wooden plywood game board is stacked and transported. This is because the synthetic resin game board 30 is slippery because the surface smoothness of the board surface is high and the friction coefficient is small as compared with the wooden plywood game board.

On the other hand, according to the present embodiment, the game boards 30 are stacked by inserting the protruding pins 60 of one game board 30 into the recesses (holes) in the reinforcing ribs 62a of the other game boards 30. Can be easily transported. Further, since the fingertips of the hand or the like can be easily inserted into the gap formed by the recessed portion 73a formed on the end surface of the outer peripheral edge reinforcing rib 73, the game board 30 can be easily lifted. Further, since the recesses 73a and 73c are formed at positions facing the outer peripheral edge reinforcing ribs 73, the fingertips of the hands and the like can be inserted into the recesses 73a and 73c from the left and right to lift them in a well-balanced manner. Further, since the recessed portion 73b is formed in the outer peripheral edge reinforcing rib 73 (located in the lower part of FIG. 7) intersecting with the outer peripheral edge reinforcing rib 73 (located in the left and right sides of FIG. 7) in which 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 conveyed in a well-balanced manner.

Next, the guide portion reinforcing member 50 will be described with reference to FIGS. 11 to 14. FIG. 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. 13 is a partially enlarged rear view of the guide portion reinforcing member 50. It is a perspective view of. The guide portion reinforcing member 50 is a member for preventing the outer rail portion 31 that first collides with the game ball launched from the game ball launching device 21 from swinging. By addressing the guide portion reinforcing member 50 to the outer rail portion 31, the outer rail portion 31 is prevented from swinging. 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 metal (stainless steel) strip-shaped thin plate, and fitting pins 31a are spot-welded to the side edges of the outer rail portion 31 in the longitudinal direction at appropriate intervals. The outer rail portion 31 is erected on the game board 30 by inserting the fitting pin 31a into the hole portion 68 formed in the game board 30.

Further, the outer rail portion 31 includes a bent portion 31b whose end edge in the longitudinal direction is bent and folded back in 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 guides the outer rail portion 31 to which the game ball launched from the game ball launching device 21 is guided. It is bent to the opposite surface side (back surface side) of the surface 31c. As a result, when the game ball launched from the game ball launching device 21 collides with the guide surface 31c of the outer rail portion 31, the edge side of the outer rail portion 31 tilts to the opposite surface side (back surface side) of the guide surface 31c. Can be prevented from doing so.

The guide portion reinforcing member 50 is provided at a position where the fitting pin 31a is arranged between the bent portion 31b and the guide portion reinforcing member 50. That is, the guide portion reinforcing member 50 is arranged between the fitting pins 31a. Since the fitting pin 31a is fixed to the outer rail portion 31 at an appropriate interval, the outer rail portion 31 easily swings between the fitting pins 31a. However, by arranging the guide portion reinforcing member 50 between the fitting pins 31a, it is possible to prevent 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 synthetic resin, and is formed in a substantially trapezoidal shape when viewed from the front (when viewed from the board surface side of the game board 30) and has an outer rail portion. The direction in which the base portion 51 located on the opposite surface side of the guide surface 31c of 31, the opposite surface side projecting portion 52 erected on the substrate portion 51, and the opposite surface side projecting portion 52 are erected. It is mainly provided with a fitting convex portion 55 projecting from the base portion 51 in the opposite direction.

The base portion 51 is a plate-shaped portion that is in close contact with the board surface of the game board 30 and is arranged along the outer rail portion 31, and the projecting portion 52 on the opposite surface side stands substantially perpendicular to the base portion 51. It is a portion that is provided and is provided in a wall shape on the edge of the base portion 51. The opposite surface side projecting portion 52 is provided along the outer rail portion 31, and the base portion 51 extends from the rear end side in a direction away from the outer rail portion 31. As a result, the base portion 51 and the projecting portion 52 on the opposite surface side are formed in a substantially L-shape when viewed from the side.

The opposite surface side projecting portion 52 is connected to an inclined portion 52a that inclines downward from the top toward the base portion 51 side (board surface side) and the inclined portion 52a, and at least one facing the outer rail portion 31. It is provided with a contact portion 52b with which the portions come into contact. A fitting convex portion 55 is projected on one side edge of the base portion 51 and the protruding portion 52 on the opposite surface side. Further, a rod-shaped columnar portion 53 is erected along the opposite surface side projecting portion 52 on the other side edge facing the one side edge of the base portion 51 and the opposite surface side projecting portion 52. The columnar portion 53 is a portion for improving the bending rigidity of the opposite surface side projecting portion 52, is formed integrally with the base portion 51 and the opposite surface side projecting portion 52, and is located on the back surface side of the contact portion 52b. As a result, the projecting portion 52 on the opposite surface side with respect to the axial direction of the columnar portion 53 can be made less likely to be bent and deformed as compared with the case where the columnar portion 53 is not formed.

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

In the columnar portion 53, a substantially triangular reinforcing portion 54 is extended 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 to the bottom side, and the bottom portion is set so as to be in close contact with the board surface of the game board 30. To. Since the substantially triangular reinforcing portion 54 is extended to the columnar portion 53 and the bottom portion of the columnar portion 53 is set so as to be in close contact with the board surface of the game board 30, the columnar portion 53 can be further prevented from being bent and deformed.

The base portion 51 is set so that the length of one side edge on which the fitting convex portion 55 is projected is shorter than the length of the other side edge facing the one side edge. By connecting the other side edge of the base portion 51 to the bottom side of the columnar portion 53 and the reinforcing portion 54, the bottom area of the base portion 51 gradually increases from one side edge of the base portion 51 toward the other side edge. It is set to be. By making the bottom area of the base portion 51 far from the fitting convex portion 55 larger than the bottom area of the base portion 51 located near the fitting convex portion 55, the bottom at a position far from the fitting convex portion 55 Area shortage can be prevented. As a result, it is possible to suppress the swing of the projecting portion 52 on the opposite surface side at a position far from the fitting convex portion 55.

Since the guide portion reinforcing member 50 includes the base portion 51 arranged along the outer rail portion 31, as shown in FIG. 11, the base portion 51 with respect to the position of the axis of the fitting convex portion 55. The position of can be shifted to the end portion (bending portion 31b) 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 and the position of the opposite surface side projecting portion 52 (contact portion 52b) can be brought close to each other. By bringing the contact portion 52b closer to the fitting pin 31a that fixes the outer rail portion 31, the outer rail portion 31 can be made 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 to be fitted into the hole portion 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 a substantially circular shape. It is formed in a columnar shape. The fitting convex portion 55 is formed with a reduced diameter portion 55a having a rounded tip. The reduced diameter portion 55a is a portion set so that the area of the cross section orthogonal to the axis becomes gradually smaller toward the tip side. Since the reduced diameter portion 55a is formed, the fitting convex portion 55 can be easily fitted and inserted into the hole portion 69. Further, since the fitting convex portion 55 and the hole portion 69 are formed in a substantially circular cross section, the fitting convex portion 55 can be made rotatable with respect to the hole portion 69, and the guide portion reinforcing member 50 can be formed. Fine position adjustment when inserting into the hole 69 can be omitted. As a result, the workability of the work 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 in which the guide portion (outer rail portion 31) and the guide portion reinforcing member 50 are installed. In addition, in FIG. 12, the position of the outer rail portion 31 arranged on the board surface of the game board 30 is illustrated by an imaginary line (dashed line).

As shown in FIG. 12, the fitting convex portion 55 includes a concave portion 56 in which a part of the outer peripheral surface is formed in a recessed shape. Since a part of the outer peripheral surface of the fitting convex portion 55 is formed in a concave shape by the concave portion 56, when the fitting convex portion 55 is fitted into the hole portion 69, the outer peripheral surface of the fitting convex portion 55 and the hole portion 69 are formed. The contact area with the inner peripheral surface of the can be reduced. As a result, the vertical effect per unit area of the hole portion 69 and the fitting convex portion 55 when the fitting convex portion 55 is fitted to the hole portion 69 can be increased. As a result, when the fitting convex portion 55 is fitted to the hole portion 69, the hole portion 69 or the fitting convex portion 55 can be easily deformed (elastic deformation or plastic deformation), so that the fitting convex portion 55 can be formed. It can be easily fitted to the hole 69.

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. Further, since the recess 56 is formed from the tip of the fitting convex portion 55 to the base end, the effect of the recess 56 can be obtained from the tip of the fitting convex portion 55 to the base end.

In the present embodiment, the concave portion 56 is formed in a sliding shape from the tip end of the fitting convex portion 55 toward the base end. As a result, the fitting convex portion 55 can be fitted to the hole portion 69 by utilizing the elastic deformation of the fitting convex portion 55 due to rubbing. As a result, the fitting convex portion 55 can be easily fitted into the hole portion 69. Further, by utilizing the elastic deformation of the fitting convex portion 55, it is possible to prevent a gap from being generated between the hole portion 69 and the fitting convex portion 55. As a result, the fitting convex portion 55 fitted in the hole portion 69 can be made less likely to rattle.

Further, in the present embodiment, the sliding direction of the recess 56 as seen from the axial direction of the fitting convex portion 55 (vertical direction on the paper surface in FIG. 12) is arranged non-parallel to the longitudinal direction of the outer rail portion 31. As a result, when the guide surface 31c is pushed to the opposite surface side (lower side in FIG. 12) by the game ball traveling toward the game area PE along the guide surface 31c of the strip-shaped outer rail portion 31, the fitting convex The portion 55 can be made difficult to elastically deform. As a result, the guide portion reinforcing member 50 can be made difficult to tilt.

That is, the fitting convex portion 55 is unlikely to be elastically deformed by a load parallel to the sliding direction, and is easily elastically deformed by a load orthogonal to the sliding direction. This is because when a load parallel to the sliding direction is applied to the fitting convex portion 55, the fitting convex portion 55 is deformed so as to reduce the gap between the slit-shaped concave portions 56. Therefore, if the guide portion reinforcing member 50 is arranged so that the sliding direction 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 surface side. When this is done, the outer rail portion 31 is likely 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 so that the sliding direction 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 opposite. When pushed to the side, the fitting convex portion 55 can be made difficult to elastically deform. As a result, the guide portion reinforcing member 50 can be made difficult to tilt.

In particular, by making the longitudinal direction of the outer rail portion 31 and the sliding direction of the concave portion 56 orthogonal to each other, it is possible to make the fitting convex portion 55 most difficult to elastically deform by a load parallel to the sliding direction. As a result, it is possible to prevent the guide portion reinforcing member 50 from tilting together with the tilt of the outer rail portion 31. As a result, it is possible to suppress the outer rail portion 31 from tilting as the game ball advances, and it is possible to stabilize the trajectory and flight distance of the game ball traveling along the outer rail portion 31.

By making the longitudinal direction of the outer rail portion 31 and the sliding direction of the recess 56 non-orthogonal, it is possible to utilize the elastic deformation of the fitting convex portion 55 by a load parallel to the sliding direction. is there. In particular, by making the longitudinal direction of the outer rail portion 31 parallel to the sliding direction of the recess 56, the elastic deformation of the fitting convex portion 55 can be most positively utilized. 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 projecting portion 52) is tilted together to elastically deform the fitting convex portion 55, and the fitting convex portion 55 is elastically deformed. By the restoring force, the guide portion reinforcing member 50 (opposite surface side projecting portion 52) and the outer rail portion 31 can be restored to their original positions. By utilizing the elastic deformation of the fitting convex portion 55, it is possible to prevent the guide portion reinforcing member 50 from being damaged by the repeatedly input load (load by the game ball). As a result, it is possible to prevent the guide portion reinforcing member 50 from being unable to regulate the tilt of the outer rail portion 31, and it is possible to stabilize the trajectory and flight distance of the game ball traveling along the outer rail portion 31.

Further, the fitting convex portion 55 is formed with a recess portion 56a having a substantially circular cross section connected to the concave portion 56 along the axis (vertical direction on the paper surface in FIG. 12) at substantially the center of the fitting convex portion 55. ing. Since the recessed portion 56a is formed, the cross-sectional area of the substantially center (near the axis) of the fitting convex portion 55 can be reduced. As a result, the cross-sectional shape of the fitting convex portions 55 on both sides of the concave portion 56 in the axial direction can be made substantially fan-shaped. As a result, when a load parallel to the sliding 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. As a result, the fitting convex portion 55 can be fitted to the hole portion 69 by utilizing the elastic deformation of the fitting convex portion 55 by the concave portion 56a. As a result, the fitting convex portion 55 can be easily fitted into the hole portion 69.

Since the elastic deformation amount of the fitting convex portion 55 by the concave portion 56a is smaller than the elastic deformation amount of the fitting convex portion 55 by the concave portion 56, the fitting convex portion in the sliding direction (substantially 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 orthogonal to the sliding (approximately the left-right direction in FIG. 12). Specifically, the amount of elastic deformation of the fitting convex portion 55 in the sliding direction (substantially vertical direction in FIG. 12) is the elastic deformation of the fitting convex portion 55 in the direction orthogonal to the sliding (substantially horizontal direction in FIG. 12). Can be smaller than the amount. Therefore, it is possible to prevent the effect of making the guide portion reinforcing member 50 difficult to tilt when the recessed portion 56a is formed from being impaired.

A part of the end face is recessed from the hole 68 (inner peripheral surface) to the outer peripheral surface on the end surface of the protruding portion 68a into which the fitting pin 31a fixed to the outer rail portion 31 is fitted and inserted into the hole portion 68. The end face groove portion 68b is formed. The end face groove portion 68b is formed in a direction along the longitudinal direction of the outer rail portion 31 arranged on the board surface of the game board 30. Since the end face groove portion 68b is formed on the end surface of the protruding portion 68a, it is possible to make it difficult to mistake the direction in which the outer rail portion 31 is arranged when the outer rail portion 31 is arranged on the game board 30.

It will be described back to FIG. As shown in FIG. 11, the guide portion reinforcing member 50 is arranged on the guide surface 31c side of the outer rail portion 31 facing the opposite surface side protrusion 52, and is provided on the guide surface side that contacts the guide surface 31c. The unit 57 is provided. As shown in FIGS. 11 and 13, the guide surface side projecting portion 57 projects from a part of the fitting convex portion 55 on the base end side (front side of the paper surface in FIG. 11) in the axial direction. A groove 58 into which the outer rail portion 31 is inserted is formed between the guide surface side protrusion 57 and the opposite surface side protrusion 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 in line XIV-XIV of FIG. As shown in FIG. 14, the guide surface side projecting portion 57 is arranged so as to face the opposite surface side projecting portion 52 at a distance substantially equal to the thickness of the outer rail portion 31. The opposite surface side projecting portion 52 is set to substantially the same height as the height of the outer rail portion 31, but the guide surface side projecting portion 57 is set 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 and the guide surface side projecting portion 57 of the guide portion reinforcing member 50, tilting of the outer rail portion 31 can be reliably prevented.

Further, since the guide surface side projecting portion 57 arranged on the guide surface 31c side of the outer rail portion 31 is set lower than the height of the opposite surface side projecting portion 52, the game ball B along the guide surface 31c It is possible to prevent the guide surface side projecting portion 57 from interfering with the progress of the guide surface. When the game ball B interferes with the guide surface side projecting portion 57, the kinetic energy of the game ball B is lost and the flight distance of the game ball B guided to the game area PE becomes unstable, but this can be prevented. , It is possible to prevent the flight distance of the game ball B guided to the game area PE from becoming unstable.

As shown in FIG. 14, the recess 56 is slidable from the tip (lower side of FIG. 14) of the fitting convex portion 55, leaving the base end (base end portion 55b) of the fitting convex portion 55 in a solid state. It is formed. As a result, the base end portion 55b of the solid fitting convex portion 55 can be fitted to the hole portion 69 (board surface side). By fitting the base end portion 55b of the solid fitting convex portion 55 to the hole portion 69 (board surface side), it is possible to prevent the fitting convex portion 55 from rattling with respect to the hole portion 69. Further, since the concave portion 56 is formed on the tip end side of the fitting convex portion 55, the fitting convex portion 55 or the hole portion 69 can be easily elastically deformed or plastically deformed, and the fitting convex portion 55 can be formed into the hole portion. It can be easily fitted to 69.

The gap between the outer peripheral surface of the fitting convex portion 55 (base end portion 55b) and the hole portion 69 is held in the groove portion 58 between the opposite surface side projecting portion 52 and the guide surface side projecting portion 57. The value is set to be smaller than the gap between the rail portion 31 and the protruding portion 52 on the opposite surface side or the protruding portion 57 on the guide surface side. While preventing rattling of the fitting convex portion 55 (base end portion 55b) fitted and inserted into the hole portion 69, when the outer rail portion 31 is fixed to the game board 30, 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 projecting portions 57. Even if a gap is formed between the opposite surface side projecting portion 52 or the guide surface side projecting portion 57 and the outer rail portion 31, the outer rail portion 31 is fixed to the game board 30 by the fitting pin 31a. It is possible to prevent the outer rail portion 31 from rattling with respect to the game board 30.

As described above, the guide portion reinforcing member 50 that regulates the tilt of the outer rail portion 31 includes a fitting convex portion 55 that fits into the hole portion 69 formed in a recess shape on the board surface of the game board 30, and a fitting convex portion 55 thereof. It is provided with a projecting portion 52 on the opposite surface side that is projected from the portion 55 and is in contact with the opposite surface side of the guide surface 31c of the outer rail portion 31. In the guide portion reinforcing member 50, the fitting convex portion 55 is fitted into the hole portion 69 formed in a recess shape on the board surface of the game board 30, and the opposite surface side protruding portion is projected from the fitting convex portion 55. 52 comes into contact with the opposite surface side of the guide surface 31c of the outer rail portion 31. As a result, it is possible to prevent the guide surface 31c from being pushed toward the opposite surface side and the band-shaped outer rail portion 31 from tilting outward due to the game ball traveling toward the game area PE along the guide surface 31c. Since the tilt of the outer rail portion 31 that guides the game ball to the game area PE can be suppressed, the trajectory and flight distance of the game ball that is guided to the game area PE can be stabilized.

That is, when the guide surface 31c is pushed toward the opposite surface side by the game ball traveling toward the game area PE along the guide surface 31c and the band-shaped outer rail portion 31 tilts, the trajectory of the game ball changes or the game ball. Kinetic energy loss occurs. As a result, the trajectory and flight distance of the game ball guided to the game area PE may become unstable.

On the other hand, according to the present embodiment, the guide surface is provided by arranging the guide portion reinforcing member 50 so that the opposite surface side projecting portion 52 comes into contact with the opposite surface side of the guide surface 31c of the outer rail portion 31. It is possible to prevent the outer rail portion 31 from tilting due to the game ball traveling toward the game area PE along the 31c. As a result, the trajectory and flight distance of the game ball guided to the game area PE can be stabilized.

Further, since the fitting convex portion 55 includes a concave portion 56 in which a part of the outer peripheral surface is formed in a recessed shape, the fitting convex portion 55 when the fitting convex portion 55 is fitted into the hole portion 69 The contact area between the outer peripheral surface and the inner peripheral surface of the hole 69 can be reduced. As a result, the vertical effect per unit area of the hole portion 69 and the fitting convex portion 55 when the fitting convex portion 55 is fitted to the hole portion 69 can be increased. As a result, when the fitting convex portion 55 is fitted to the hole portion 69, the hole portion 69 or the fitting convex portion 55 can be easily deformed (elastic deformation or plastic deformation), so that the fitting convex portion 55 can be formed. It can be easily fitted to the hole 69.

Further, since the concave portion 56 is formed in a sliding shape from the tip of the fitting convex portion 55 toward the proximal end (base end portion 55b), the elastic deformation of the fitting convex portion 55 due to the sliding is utilized. , The fitting convex portion 55 can be fitted into the hole portion 69. As a result, the fitting convex portion 55 can be easily fitted to the hole portion 69, and a gap is prevented from being generated between the hole portion 69 and the fitting convex portion 55 by utilizing the elastic deformation of the fitting convex portion 55. Therefore, the fitting convex portion 55 fitted in the hole portion 69 can be prevented from rattling.

Further, since the sliding direction of the recess 56 when viewed from the axial direction of the fitting convex portion 55 is arranged non-parallel to the longitudinal direction of the outer rail portion 31, the strip-shaped outer rail portion 31 is along the guide surface 31c. When the guide surface 31c is pushed toward the opposite surface side by the game ball traveling toward the game area PE, the fitting convex portion 55 can be made difficult to elastically deform. As a result, it is possible to prevent the outer rail portion 31 from tilting. As a result, the trajectory and flight distance of the game ball guided to the game area PE can be further stabilized.

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

Further, the opposite surface side projecting portion 52 is connected to an inclined portion 52a that inclines downward from the top portion toward the outside in the axial direction of the fitting convex portion 55, and the inclined portion 52a, and is connected to the inclined portion 52a and is connected to the opposite surface of the outer rail portion 31. Since it is provided with the contact portion 52b which is in contact with at least a part of the opposite surface while facing the guide portion reinforcing member 50, the work of arranging the guide portion reinforcing member 50 and the outer rail portion 31 on the board surface of the game board 30 can be facilitated.

That is, when the guide portion reinforcing member 50 and the outer rail portion 31 are arranged 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 is set on the game board 30. It is inserted into the hole 69. Since the fitting convex portion 55 is formed with a sliding concave portion 56, when the fitting convex portion 55 is inserted into the hole portion 69 of the game board 30, the fitting convex portion 55 is formed so as to narrow the interval between the sliding concave portions 56. Deform. Therefore, it is possible to easily insert about half the length of the fitting convex portion 55 into the hole portion 69 of the game board 30.

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

When the outer rail portion 31 is moved in the direction orthogonal 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 comes into contact with the inclined portion 52a, the outer rail As the portion 31 approaches the game board 30, the inclined portion 52a is pushed in the horizontal direction with respect to the board surface, and the guide portion reinforcing member 50 rotates about the fitting convex portion 55. When the outer rail portion 31 separates from the inclined portion 52a and faces the contact portion 52b, no force is generated to rotate the guide portion reinforcing member 50, so that the position of the guide portion reinforcing member 50 is determined.

Further, while accommodating the outer rail portion 31 in the groove portion 58 between the contact portion 52b and the guide surface side projecting portion 57, the fitting pin 31a fixed to the outer rail portion 31 is fitted and inserted into the hole portion 68. I will go. As the fitting pin 31a is inserted into the hole portion 68, the base end side end surface of the fitting convex portion 55 is pushed against the side edge of the outer rail portion 31, and the fitting convex portion 55 is gradually fitted into the hole portion 69. .. As a result, the workability of the arrangement work of arranging the outer rail portion 31 on the board surface of the game board 30 can be improved.

Since the base end portion 55b of the fitting convex portion 55 is formed in a solid state, the base end portion 55b is fitted into the hole portion 69. As a result, it is possible to prevent the fitting convex portion 55 from rattling in the hole portion 69.

Further, since the protruding portion 69a protrudes toward the back surface side from the thin portion 72 of the game board 30, and the hole portion 69 is formed through the protruding portion 69a and the thin portion 72, it is fitted into the hole portion 69. The fitting depth of the fitting protrusion 55 can be secured. As the fitting depth of the fitting convex portion 55 fitted to the hole portion 69 increases, the fitting convex portion 55 fitted to the hole portion 69 tends to be less likely to swing in the direction orthogonal to the axial direction. Therefore, by ensuring the fitting depth of the fitting convex portion 55 fitted in the hole portion 69, it is possible to make it difficult for the guide portion reinforcing member 50 fixed to the game board 30 to swing. By making it difficult for the guide portion reinforcing member 50 fixed to the game board 30 to swing, the tilt of the outer rail portion 31 that guides the game ball to the game area PE can be suppressed, so that the game ball guided to the game area PE can be suppressed. The trajectory and flight distance of the vehicle can be further stabilized.

Further, since the protruding portion 69a is coupled to the thin portion 72 and the hole portion 69 is formed through the protruding portion 69a and the thin portion 72, the area of the thick portion 70 is expanded in order to form the hole portion 69. Can be unnecessary. The mass of the game board 30 increases by the amount of the protruding portion 69a (excluding the hole 69) coupled to the thin portion 72, but since it is not necessary to increase the area of the thick portion 70, the mass of the game board 30 The increase can be suppressed. Further, since the protruding portion 69a through which the hole portion 69 is formed penetrates the function of a rib that increases the rigidity of the thin portion 72 around the hole portion 69, the rigidity of the thin portion 72 around the hole portion 69 can be ensured. Therefore, the nails can be planted in the thick portion 70 to secure the holding force of the nails, and the weight of the game board 30 can be reduced while ensuring the rigidity of the game board 30. In addition, the trajectory and flight distance of the game ball guided to the game area PE can be further stabilized.

Next, with reference to FIG. 15, the guide portion reinforcing member 50 in another embodiment will be described. The same parts as those in the first embodiment are designated by the same reference numerals, and the following description will be omitted. FIG. 15 (a) is a partially enlarged rear view of the game board 30 in which the guide portion reinforcing member 80 in another embodiment is installed, and FIG. 15 (b) is a game in which the guide portion reinforcing member 90 in another embodiment is installed. It is a partially enlarged rear view of a board 30. In addition, in FIGS. 15A and 15B, the fitting convex portions 85, 95 of the guide portion reinforcing members 80, 90 are fitted into the hole portion 69 formed in the game board 30 from the board surface (front surface) side. However, the state seen from the back side of the game board 30 is shown.

The guide portion reinforcing member 80 shown in FIG. 15A is a part of the outer peripheral surface along the axial direction (the direction perpendicular to the paper surface in FIG. 15A) at two locations at axially symmetric positions on the outer peripheral surface of the fitting convex portion 85. Is provided with a recess 86 formed in a recessed shape. Since the fitting convex portion 85 includes a concave portion 86 in which a part of the outer peripheral surface is formed in a recessed shape, the outer peripheral surface of the fitting convex portion 85 when the fitting convex portion 85 is fitted into the hole portion 69. The contact area between the hole 69 and the inner peripheral surface of the hole 69 can be reduced. As a result, the vertical effect per unit area of the hole portion 69 and the fitting convex portion 85 when the fitting convex portion 85 is fitted to the hole portion 69 can be increased. As a result, when the fitting convex portion 85 is fitted to the hole portion 69, the hole portion 69 or the fitting convex portion 85 can be easily deformed (elastic deformation or plastic deformation), so that the fitting convex portion 85 can be formed. It can be easily fitted to the hole 69.

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

In particular, since the concave portion 86 is formed in a shape in which two portions are cut off along the axial direction of the fitting convex portion 85, it is possible to prevent the outer peripheral surface of the fitting convex portion 85 from becoming excessively small. A contact area with the inner peripheral surface of the hole 69 can be secured. Since it is possible to prevent the vertical effect of the outer peripheral surface of the fitting convex portion 85 from becoming excessive per unit area, it is possible to suppress deformation such as buckling of the outer peripheral surface of the fitting convex portion 85. As a result, it is possible to prevent problems such as rattling of the fitting convex portion 85 due to a gap between the outer peripheral surface of the fitting convex portion 85 and the inner peripheral surface of the hole portion 69.

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 in FIG. 15 (b)) at four locations at axially symmetric positions on the outer peripheral surface of the fitting convex portion 95. Is provided with a recess 96 formed in a recessed shape. Since the fitting convex portion 95 includes a concave portion 96 in which a part of the outer peripheral surface is formed in a recessed shape, the outer peripheral surface of the fitting convex portion 95 when the fitting convex portion 95 is fitted into the hole portion 69. The contact area between the hole 69 and the inner peripheral surface of the hole 69 can be reduced. As a result, the vertical effect per unit area of the hole portion 69 and the fitting convex portion 95 when the fitting convex portion 95 is fitted to the hole portion 69 can be increased. As a result, when the fitting convex portion 95 is fitted to the hole portion 69, the hole portion 69 or the fitting convex portion 95 can be easily deformed (elastic deformation or plastic deformation), so that the fitting convex portion 95 can be formed. It can be easily fitted to the hole 69.

Further, a concave portion 95a having a circular cross section is formed at substantially the center of the fitting convex portion 95 from the tip of the fitting convex portion 95 along the axial direction of the fitting convex portion 95. By reducing the cross-sectional area of the fitting convex portion 95 by the recessed portion 95a, the fitting convex portion 95 can be easily elastically deformed by the vertical effect acting on the fitting convex portion 95. As a result, the fitting convex portion 95 can be more easily fitted into the hole portion 69, so that workability when the fitting convex portion 95 is fitted and inserted into the hole portion 69 can be improved. Further, by making the fitting convex portion 95 elastically deformed, it is possible to prevent the fitting convex portion 95 from rattling with respect to the hole portion 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 through the game board 30 in the thickness direction 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 161 is formed through the game board 130 in the thickness direction and a part of the outer peripheral edge of the game board 130 is opened will be described. The same parts as those in the first embodiment are designated by the same reference numerals, and the following description will be omitted. FIG. 16 is a front view of the game board 130 and the structure 170, which are the main configurations of the pachinko machine 1 in the second embodiment.

As shown in FIG. 16, the game board 130 has an opening 161 that is formed through the game board 130 in the thickness direction (vertical direction on the paper surface of FIG. 16) and a part of the outer peripheral edge of the game board 130 is opened, and an opening 161 thereof. It includes a structure 170 that connects the peripheral edges of the opening 161 to each other. In the present embodiment, a part of the outer peripheral edge of the game board 130 located on the right side when viewed from the front is opened by the opening 161. By forming the opening 161 the board surface of the game board 130 is formed in a substantially C shape.

The structure 170 is connected between one predetermined portion 161a of the peripheral edge of the opening 161 of the game board 130 and the other predetermined portion 161b. In the present embodiment, the structure 170 is formed in a substantially rectangular shape when viewed from the front, and two openings 161 are connected along the outer peripheral edge of the game board 130. The game board 130 and the structure 170 are made of a translucent synthetic resin, similarly to the game board 30 described in the first embodiment. Further, a symbol display device 43a (see FIG. 5) is arranged inside the opening 161 in which a part of the outer peripheral edge is closed by the structure 170, as in the first embodiment.

Next, the connection structure between the game board 130 and the structure 170 will be described with reference to FIG. FIG. 17 is a perspective view of the game board 130 and the structure 170. Note that FIG. 17 shows a state in which the structure 170 is separated from the game board 130. As shown in FIG. 17, the structure 170 projects from the front side of the main body 172 formed in a box shape of a substantially rectangular parallelepiped and the main body 172 to the upper and lower sides (in a direction substantially parallel to the board surface of the game board 30). It is mainly provided with an engaging portion 171 formed in a brim shape.

A symbol display device (not shown) that variablely displays a plurality of symbols is built in the main body 172, and a symbol display unit 173 (decorative portion) such as a liquid crystal display is arranged on the front surface of the main body 172. .. The symbol display unit 173 is not limited to the liquid crystal display, and other display screens such as CRT, dot matrix, and 7 segments can be appropriately selected.

The engaging portion 171 is formed through an insertion hole 174 into which a shaft-shaped member such as a screw for fixing the structure 170 to the game board 130 is screwed.

In the game board 130, a connecting portion (engaged portion) 131 for receiving the engaging portion 171 provided in the structure 170 is formed on a part of the peripheral edge of the opening 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 stepped flat surface set one step lower than the board surface of the game board 130. The depth of the connecting portion 131 with respect to the board surface of the game board 130 (FIG. 17 left-right direction) is set to be substantially the same as the thickness of the engaging portion 171 (FIG. 17 left-right direction).

Further, a light scattering portion 132 is provided on the back surface side of the connecting portion 131. The light scattering unit 132 is a portion for scattering the light emitted from the light emitting unit 181 (described later) such as an LED arranged on the back surface side of the game board 130 to the game board 130. The light scattering portion 132 is formed by a ridge provided in a vertical or horizontal direction, a ridge provided in a direction intersecting vertically and horizontally, a wavy protrusion, or the like.

The connecting portion 131 is formed through an insertion hole 133 in which an insertion hole 174 formed in the structure 170 (engagement portion 171) is connected in the axial direction and a shaft-shaped member such as a screw is screwed into the connecting portion 131. The structure 170 can be connected to the game board 130 by connecting the connecting portion 131 and the engaging portion 171 with a shaft-shaped member such as a screw screwed into the insertion holes 133 and 174.

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

The light emitted from the light emitting unit 181 (indicated by a two-point chain line in FIG. 18) enters and exits the light scattering unit 132 (engaged unit 131) due to the difference in the refractive index between the air and the light scattering unit 132. Sometimes refracted. Therefore, if the light emitting unit 181 is made to emit light, it is possible to realize an illumination in which the light is dispersed in a large number or in a state with a three-dimensional effect. As a result, in addition to the effect of the symbol display unit 173 (decorative unit), the effect of the light from the light emitting unit 181 can be improved.

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

Further, when the board surface (surface) of the game board 130 is processed into a ridge or a protrusion to provide the light scattering part 132, the unevenness of the light scattering part 132 interferes with the movement of the game ball. When the light scattering unit 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 game ball due to the light scattering unit 132 (unevenness). As a result, the flexibility of the design of the game board 130 can be ensured.

Further, when the light scattering portion 132 is provided on the back surface side (back surface) of the game board 130 (connecting portion 131), the shape of the light scattering portion 132 can be designed relatively freely. Since the outer peripheral edge reinforcing rib 73 (see FIG. 17) that stands up toward the back surface side is provided on the outer peripheral edge of the game board 130, the outer peripheral edge reinforcing rib 73 is provided on the back surface side (back surface side) of the game board 130. This is because space can be secured.

Further, by scattering the light by the light scattering portion 132, the shadow of a shaft-shaped member (not shown) such as a screw screwed into the insertion holes 133 and 174 is cast from the board surface of the game board 130 and the front surface of the structure 170. It can be prevented from being visually recognized. This is because the light can be circulated in front of the shaft-shaped member (not shown) by scattering the light by the light scattering unit 132. As a result, the joint portion (connecting portion 131 and engaging portion 171) between the game board 130 and the structure 170 can be made difficult to see by the light scattered by the light scattering part 132, and the game board 130 and the structure 170 can be combined with each other. The effect of the seam can be improved.

According to the pachinko machine 1 configured as described above, a part of the outer peripheral edge of the game board 130 is opened in the opening 161 formed through the game board 130 in the thickness direction, and 2 of the peripheral edge of the opening 161 is opened. The locations are connected by a structure 170. As a result, the structure 170 can be made into a three-dimensional structure using the space in the thickness direction of the game board 130. Since the structure 170 includes a symbol display portion 173 (decorative portion), it is possible to carry out a three-dimensional effect using the space in the thickness direction of the game board 130. As a result, the interest of the game can be greatly enhanced.

Here, in the conventional structure in which parts such as a display device and an accessory are attached to the board surface of the game board, the spread in the depth direction is poor, so that a similar effect is easily adopted, and it is difficult to enhance the interest of the game. In addition, in the game board made of conventional wooden plywood (veneer), considering the workability and mechanical strength of the wooden plywood, a structure with an opening that opens a part of the outer peripheral edge of the game board is adopted. hard.

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

Further, a symbol display device 43a (see FIG. 5) having a display unit for variablely displaying the symbol is provided in the opening 161 and the structure 170 is arranged around the symbol display device 43a. The symbol display unit 173 (decorative portion) of the 170 can realize not only a flat design effect of the symbol display device 43a but also a three-dimensional effect using the space in the thickness direction of the game board 130. Further, since the structure 170 is unitized as a game part having a symbol display portion 173 (decorative portion), the structure 170 can be easily attached to or replaced with the game board 130.

When projected in the direction), it is provided at a position that does not interfere with the projected line of the inner rail portion 32 shown on the orthogonal plane (paper surface in FIG. 29 (a)) 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 the hole portion 68 for mounting the outer rail portion 31 is formed to penetrate along the axial direction (the direction perpendicular to the paper surface in FIG. 29A). ing. As shown in FIG. 29B, the rail receiving portion 533 has a flat surface-shaped receiving portion 533a formed on the end surface in the axial direction. The distance from the board surface 530a to the receiving portion 533a (height of the rail receiving portion 533) is set to a value smaller than the distance from the board surface 530a to the end surface 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 530a to the receiver portion 532c of the rail receiver 532 (height of the receiver portion 532c).

It should be noted that the end faces formed on the axial end surface of the projecting portion 69a holding the fitting convex portion 55 of the guide portion reinforcing member 550 and the axial end surface of the projecting portion 68a holding the fitting pin 31a of the outer rail portion 31. The groove portion 68b (see FIG. 12) also functions as a receiving portion of the rail receiver (a part of the back surface side contact portion). The height from the board surface 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 the portion shown by XXXa in FIG. 26 in an enlarged manner, and FIG. 30 (b) is a game board seen from the direction of arrow XXXb in FIG. It is a partially enlarged side view of 530. In FIG. 30A, the outer rail portion 31 arranged on the board surface of the game board 530 (the surface on the back side of the paper surface in FIG. 30A) is shown by a broken line.

As shown in FIGS. 30A and 30B, the rail receiver 532 is provided on the inclined surface portion 71 of the game board 530, and the hole portion 68 for mounting the outer rail portion 31 is provided in the axial direction. It is formed through (in the direction perpendicular to the paper surface in FIG. 30A). The protrusions 532a and 532b projecting from the axial end faces of the rail receiver 532 have the outer rail portions 31 arranged on the board surface 530a side in the thickness direction of the game board 530 from the board surface side 530a (FIG. 29 (a) perpendicular to the paper surface). When projected in the direction), it is provided at a position that does not interfere with the projected line of the outer rail portion 31 shown on the orthogonal plane (paper surface in FIG. 29 (a)) orthogonal to the thickness direction of the game board 530.

The rail receiver 534 is formed in the vicinity of the reference hole 534a (see FIG. 30), which serves as a positioning reference in the manufacturing process of the game board 530, and is coupled 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 the other game board 530 when a plurality of game boards 530 on which the outer rail portion 31 and the inner rail portion 32 are mounted are stacked. The rail receiver 534 has a semi-cylindrical shape, and projects from the back surface of the game board 530 along the thickness direction of the game board 530 (FIG. 30 (a) in the vertical direction on the paper surface).

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

As shown in FIG. 30B, the distance from the board surface 530a to the axial end face of the rail receiver 534 (height of the rail receiver 534) is the distance from the board surface 530a to the end face of the outer peripheral edge reinforcing rib 531 (outer peripheral edge reinforcement). The height of the rib 531) is set to be the same. Further, the distance from the board surface 530a to the receiving portion 534c (height of the receiving portion 534c) is set to a value smaller than the height of the outer peripheral edge reinforcing rib 531. Further, 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 (height of the receiving portion 532c). Since the receiving portion 534c is coupled to the upper side of the outer peripheral edge reinforcing rib 531 of the game board 530, it is excellent in stability that regulates the position when the game boards 530 are stacked.

Next, FIG. 31 (a) is a partially enlarged rear view of the game board 530 in which the portion shown by XXXIa in FIG. 26 is enlarged, and FIG. 31 (b) is the line XXXIb-XXXIb in FIG. 31 (a). It is a top view of the cut portion. In FIG. 31 (a), the inner rail portion 32 arranged on the board surface of the game board 530 (the surface on the back side of the paper surface in 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 portion 71 of the game board 530, and the hole portion 68 for mounting the inner rail portion 32 is provided in the axial direction (FIG. 31 (a)). It is formed through along the vertical direction of the paper surface). An annular reinforcing rib 535 is erected on the back surface of the game board 530 around the out port 39, and holes 68 are formed on both the left and right sides of the out port 39. As a result, the inner rail portions 32 can be firmly fixed to the game board 530 on both sides of the out port 39 into which the game balls that could not enter the ball entry portion provided in the game area PE flow.

The inner rail portion 32 includes a bay exit 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 bay exit portion 32a is a portion for facilitating the inflow of the game ball into the out port 39, and the game ball that has flowed down the game area PE and reached the lower end of the inner rail portion 32 is exited by the bay exit portion 32a. It can be quickly flowed into 39.

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 erected on both sides of the relief portion 535a. The relief portion 535a has the thickness of the game board 530 when the inner rail portion 32 arranged on the board surface 530a side is projected from the board surface side 530a in the thickness direction of the game board 530 (FIG. 31 (a) in the direction perpendicular to the paper surface). It is provided at a position intersecting the projection line of the inner rail portion 32 shown on the orthogonal plane (paper surface shown in FIG. 31 (a)) orthogonal to the direction. The width of the relief portion 535a defined by the wall portion 535b (vertical direction in FIG. 31A) is set to be larger than the width of the receiving portion 532c.

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

Next, with reference to FIGS. 32 and 33 (a), a state when a plurality of game boards 530 are stacked will be described. 32 and 33A are end view views of the cut portion schematically showing a state in which a plurality of game boards 530 are stacked. In the manufacturing process of the game board 530, first, a hole 68 for attaching the fitting pins 31a, 32a, etc. and a nail (obstacle nail) 536 are inserted into the plate material for the game board made of synthetic resin. A pilot hole (mounting hole) is formed. Next, a nail 536 is planted, and a small part (not shown) such as a wind turbine, an outer rail portion 31 and an inner rail portion 32 are attached. Next, large parts (not shown) such as a large winning device and a control circuit board are assembled. Assembling large parts complicates the work and reduces the process capability. Due to the imbalance of process capability, the game board 530 in the middle of manufacturing may temporarily stay between processes. In such a case, the game board 530 in the middle of manufacturing to which the nail 536, the outer rail part 31 and the inner rail part 32 are attached is temporarily stacked, and the stagnant game board 530 waiting for the next process is made to stand by.

In the game board 530, the height of the outer peripheral edge reinforcing rib 531, the height of the rail receivers 532, 534, and the height of the reinforcing rib 535 are set to the same values with respect to the board surface 530a, so that the game board 530 It can be placed flat on the flat surface G of the waiting place with the back side facing down. Further, the outer peripheral edge reinforcing rib 531 is projected from the entire circumference of the thin portion 72, and the rail receivers 532, 534 and the reinforcing rib 535 are dispersed around the thick portion 70 formed in a substantially circular shape. , The outer peripheral edge reinforcing rib 531 and the rail receivers 532, 534 and the reinforcing rib 535 can be distributed and burdened.

When stacking another game board 530 on the game board 530 placed flat on the flat surface G, the other game board 530 is placed on the side edge of the outer rail portion 31 and the inner rail portion 32 erected on the board surface 530a of the game board 530. The rail receivers 532, 533, 534 of the game board 530 are brought into contact with the receiving portions 532c, 533a, 534c. 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 531c and 531d (see FIG. 33) of the other game board 530. Since the strip-shaped 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 receiving 531c, 531d.

By repeating this, the game boards 530 can be stacked one after another. As a result, since the outer rail portion 31 and the inner rail portion 32 receive the load of the stacked upper game board 530, the nail 536 planted on the board surface 530a of the game board 530 does not come into contact with the back surface of the game board 530. In this case, the load of the upper game board 530 applied to the nail 536 of the stacked lower game board 530 can be reduced to zero. Further, even when the nail 536 planted on the board surface 530a of the game board 530 comes into contact with the back surface 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 is applied to the rail. It can be made smaller by being dispersed in the receivers 532, 533, 534, the outer peripheral rail receivers 531c, 531d, the outer rail portion 31, and the inner rail portion 32. As a result, when the game boards 530 are stacked, it is possible to prevent adverse effects such as bending of the nails 536 planted in the game board 530.

Since the outer rail portion 31 and the inner rail portion 32 are arranged on the board surface 530a of the game board 530 while being curved in an arc shape when the board surface 530a is viewed from the front, the thickness direction of the game board 530 (vertical direction in FIG. 32). ) Rigidity can be secured. Therefore, when the load of the stacked upper game boards 530 is applied to the outer rail portion 31 and the inner rail portion 32, it is possible to prevent problems such as bending of the outer rail portion 31 and the inner rail portion 32. Therefore, it is possible to stack the game board 530 without adversely affecting the nail 536, the outer rail portion 31 and the inner rail portion 32 planted on the board surface 530a.

Further, the rail receivers 532, 533, 534 (receivers 532c, 533a, 534c) are used when a plurality of game boards 530 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 height of the game board 530 in the thickness direction is set so that the nail 536 planted on the board surface 530a does not come into contact with the back surface of the game board 530. As a result, the load of the upper game board 530 applied to the nail 536 of the stacked lower game board 530 can be reduced to zero. As a result, when the game boards 530 are stacked, it is possible to reliably prevent adverse effects such as bending of the nails 536 planted in the game board 530.

Further, since the rail receivers 532, 533, 534 (reception portions 532c, 533a, 534c) (rear side contact portions) are provided on the back surface of the game board 530, the protruding length of the nail 536 from the board surface 530a is outside. The height of the rail portion 31 and the inner rail portion 32 can be equal to or larger than the height. In that case, when the game board 530 is attached to the main body frame 3 (see FIG. 2) and the front door frame 4 is closed to configure the pachinko machine 1, the back surface 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 prevent a problem that the game ball is caught between the back surface of the glass 14 and the tip of the nail 536 during the game.

Further, in the rail receivers 532 and 534, the receiving surfaces 532a1,532b1,534b along the longitudinal side surfaces 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. Has been done. As a result, when the positions of the stacked game boards 530 shift 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 become the outer rail portion 31 and the inner rail portion 32. At the end, further misalignment of the game board 530 is prevented. As a result, the side edges of the outer rail portion 31 and the inner rail portion 32 can be maintained in contact with the receiving portions 532c and 534c, so that the stacked upper game boards 530 can be prevented from slipping down.

Further, the outer rail portion 31 and the inner rail portion 32 have fitting pins 31a and 32a projecting from their side edges toward the outer side in the width direction of the outer rail portion 31 and the inner rail portion 32. On the other hand, in the game board 530, a hole 68 into which the fitting pins 31a and 32a are fitted is formed, and the fitting pins 31a and 32a are fitted and inserted into the hole 68 so that the outer rail portion 31 and the inside of the game board 530 are fitted. The rail portion 32 is mounted. Since the hole 68 is formed at the position of the rail receiver 532, 533, the depth of the hole 68 can be secured by the height of the rail receiver 532, 533 in the thickness direction of the game board 530. As a result, the holding force of the fitting pins 31a and 32a fitted and inserted into the hole 68 can be increased. Therefore, by firmly fixing the fitting pins 31a and 32a to the game board 530, the outer rail portion 31 and the inner rail portion 32 can be firmly fixed to the game board 530.

Further, since relief portions 535a wider than the receiving portion 532c are formed on the left and right sides of the reinforcing rib 535 (see FIG. 31 (a)), the bay out portions 32a formed on the inner rail portion 32 are stacked. It is possible to prevent the game board 530 from interfering with the reinforcing rib 535. Further, since the height of the relief portion 535a (see FIG. 31B) from the board surface 530a is set lower than that of the receiving portion 532c, the height of the bay exit portion 32a (FIG. 31 (a) in the vertical direction of the paper surface). Is set to a value larger than the height of the inner rail portion 32, it is possible to prevent the bay exit portion 32a from interfering with the relief portion 535a of the stacked game boards 530. As a result, it is possible to prevent the curved portion 32a from having an adverse effect such as the bay out portion 32a being plastically deformed to change its shape while the plurality of game boards 530 are stacked and waiting.

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

On the other hand, when the height of the outer peripheral rail receivers 531c and 531d in the thickness direction of the game board 530 is set to a value larger than the height of the outer peripheral reinforcing rib 531, it is placed on the flat surface G. The smashed game board 530 rattles. The game board 530 can solve this problem, and the game board 530 placed flat on the flat surface G with the outer peripheral edge reinforcing rib 531 facing downward can be prevented from rattling and can be stably placed. Further, when lifting the flatly placed game board 530, the fingertips and the like inserted into the outer peripheral rail receivers 531c and 531d can be used as clues to improve the handleability of the game board 530 in the middle of manufacture and the completed game board 530. Can be improved.

Further, since the heights of the outer peripheral edge rail receivers 531c and 531d in the thickness direction of the game board 530 are set to the same values as the rail receivers 532, 533, 534 (receivers 532c, 533a, 534c). 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 made substantially parallel. As a result, a plurality of game boards 530 can be stacked substantially vertically, and the stacked game boards 530 can be made difficult to slide down. Further, it is prevented that the outer rail portion 31 of the game board 530 interferes with the outer peripheral rail receivers 531c and 531d of the stacked game board 530. As a result, it is possible to prevent adverse effects such as deformation of the outer rail portion 31 while the plurality of game boards 530 are stacked and stand by.

Further, when a plurality of game boards 530 are stacked, the outer rail portion 31 includes a protruding portion (rail receiver) 69a provided on the other game board 530, a rail receiver 533 (standing on the thin portion 72), and a rail. It abuts on the receivers 532 and 534 and the outer peripheral rail receivers 531c and 531d. On the other hand, the inner rail portion 32 comes into contact with the rail receiver 532 (the one erected on the inclined surface portion 71) provided on the other game board 530.

Here, the game ball launched from the game ball launching device 21 moves along the outer rail portion 31 by centrifugal force and is guided to the game area PE. Therefore, the curvature of the outer rail portion 31 and the like affect the trajectory of the game ball driven into the game area PE. On the other hand, since the inner rail portion 32 is arranged inside the outer rail portion 31, the influence of the curvature of the inner rail portion 32 on the trajectory of the game 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 receiver 532 and the like coming into contact with the inner rail portion 32 and the outer rail 31, so that the load of the stacked game boards 530 is applied to the outer rail portion 31. It is prevented that the load is concentrated on the rail. That is, by distributing 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. As a result, it is possible to prevent the outer rail portion 31 from being plastically deformed by stacking the game boards 530. Therefore, the trajectory of the game ball driven into the game area PE can be stabilized.

Further, the contact area between the rail receiver 534 and the outer peripheral rail receivers 531c and 531d 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 by the rail receiver 534 and the outer peripheral rail receivers 531c and 531d can be reduced. As a result, the 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 driven from the game ball launching device 21 into the game area PE. This is because the game ball moves along the outer rail portion 31 facing the inner rail portion 32 due to centrifugal force. On the other hand, the region U (see FIG. 24) of the outer rail portion 31 located on the right side of the reference hole 534a when the game board 530 is viewed from the front has a relatively small influence on the trajectory of the game ball driven into the game area PE. .. This is because the trajectory of the game ball moving along the region U is restricted by the shape and arrangement of not only the outer rail portion 31 but also the board surface parts such as the center frame 47.

Therefore, when a plurality of game boards 530 are stacked, the height of the rail receivers 532 and 534 is such that the rail receivers 532 and 534 located in the region U of the outer rail portion 31 and its vicinity abut on the outer rail portion 31. It is valid to set. This is because even if the outer rail portion 31 (region U) is plastically deformed by the load of the stacked game boards 530, the influence on the trajectory of the game ball is small.

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 parts other than the area U are not in contact with the rail receiver 532 or the like of the other game board 530. Set the height of the receiver 532 and so on. The height of the inner rail portion 32 is set so that the rail receiver 532 or the like of the other game board 530 is in contact with the rail receiver 532 or the like. As a result, the region U of the outer rail portion 31 and the inner rail portion 32 come into contact with the rail receiver 532 or the like of the other game board 530, so that the plurality of game boards 530 are stacked. As a result, in the outer rail portion 31, the load of the stacked game board 530 is applied to the portion (the portion other than the region U) that greatly affects the trajectory of the game ball driven from the game ball launching device 21 into the game area PE. It can be prevented from being done. As a result, it is possible to prevent a portion (a portion other than the region U) that greatly affects the trajectory of the game ball driven into the game region PE from being adversely affected by the load of the stacked game boards 530.

Further, in addition to the rail receiver 532 arranged in the region U of the outer rail portion 31, the rail receiver 534 (see FIG. 26) arranged in the vicinity of the region U of the outer rail portion 31 is used to stack the game boards 530. 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 receiving portion 534c (FIG. 30) can be secured. Therefore, when the outer rail portion 31 is supported, it is compared with the case where the rail receiver 534 is not used. Therefore, the load acting per unit area of the outer rail portion 31 can be reduced. As a result, as compared with the case where the rail receiver 534 is not used, the load of the stacked game boards 530 can make it less likely that the region U of the outer rail portion 31 is adversely affected.

In the present embodiment, the region U of the outer rail portion 31 comes into contact with the rail receiver 532 of the other game board 530, and the portion other than the region U (outer rail portion 31) is the rail receiver 532 of the other game board 530. Although the case where the height of the rail receiver 532 or the like is set so as to be non-contact with the above is described, the area U of the outer rail portion 31 is also a rail so as to be non-contact with the rail receiver 532 of the other game board 530. Of course, it is possible to set the height of the receiver 532. As a result, it is possible to prevent the load of the stacked game boards 530 from being applied to the outer rail portion 31, and thus it is possible to prevent the outer rail portion 31 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 have almost no effect on 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 will be described with reference to FIG. 33 (b). 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 531d and the rail receiver 532 has been described. On the other hand, in another embodiment shown in FIG. 33B, a 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 designated by the same reference numerals, and the following description will be omitted. FIG. 33B is an end view of a cut portion schematically showing a state in which a plurality of game boards 560 in another embodiment are stacked.

As shown in FIG. 33 (b), the game board 560 is mounted on the pachinko machine 1 (see FIG. 2), and the outer rail portion 31 projects from the outer peripheral edge on the left side when the game board 560 is viewed from the front. A passage forming member 538 (a type of rail member) is arranged in the vicinity of the outer peripheral edge on the right side of the board surface. The passage forming member 538 is a member made of synthetic resin for partitioning the game area PE by being continuously provided with the inner rail portion 32, and is fixed to the right side of the board surface of the game board 560 with screws or the like. The height of the passage forming member 538 from the board surface is set to be substantially the same as the height of the outer rail portion 31 and the inner rail portion 32 from the board surface.

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

The game board 560 includes a hole 68 formed through the hole 68 in the thickness direction, and a protrusion 537 is provided around the hole 68. The axial length of the protrusion 537 (vertical direction in FIG. 33 (b)) is set to a value shorter than the axial length of the rail receiver 532 (see FIG. 33 (a)). Therefore, when a 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 protruding portion 537 are in a non-contact state. Therefore, the game board 560 is placed on and stacked on the outer rail portion 31 and the passage forming member 538 by the outer peripheral rail receivers 531d and 531f. Since the outer peripheral edge reinforcing ribs 531 are provided with the outer peripheral edge rail receivers 531d and 531f, even if the outer rail portion 31 and the passage forming member 538 are arranged so as to project from the outer peripheral edge of the game board 560, the game board 560 The outer rail portion 31, the passage forming member 538, and the outer peripheral edge reinforcing rib 531 can be prevented from interfering with each other when the outer rail portion 31 and the passage forming member 538 are stacked. As a result, the game area PE of the game board 560 can be greatly expanded.

Next, another embodiment of the rail receiver 532 will be described with reference to FIG. 34. In the sixth embodiment, a case where projecting portions 532a and 532b facing each other are projected 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, a case where one of the protrusions 532a and 532b is projected from the receiving portion 532c will be described. The same parts as those in the sixth embodiment are designated by the same reference numerals, and the following description will be omitted. 34 (a) and 34 (b) are end view views of a cut portion schematically showing a state in which a plurality of game boards 570 and 580 are stacked in another embodiment.

As shown in FIG. 34 (a), each rail receiver 542 is provided with a protrusion 532b located on the thick portion 70 side (center side of the game board). Since the protruding portion 532b (receiving surface 532b1) faces the outer rail portion 31 and the inner rail portion 32, it is possible to prevent the stacked game boards 570 from shifting in position and prevent the game board 570 from slipping down.

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 (outer peripheral side of the game board). Since the protruding portion 532a (receiving surface 532a1) faces the outer rail portion 31 and the inner rail portion 32, it is possible to prevent the stacked game boards 580 from shifting in position and prevent the game board 580 from slipping down.

Next, the guide portion reinforcing member 550 fixed to the board surface 530a of the game board 530 will be described with reference to FIGS. 35 and 36. 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 with the contact portion 52b of the guide portion reinforcing member 50 is formed to have substantially the same width with respect to the distance away from the fitting convex portion 55 when viewed from the front. The case was explained. On the other hand, in the present embodiment, the case where the inclined portion 553 is formed so that the width in the front view increases as the distance from the fitting convex portion 55 increases will be described. The same parts as those described in the first embodiment are designated by the same reference numerals, and the following description 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 the line XXXVb-XXXVb of FIG. 35 (a). It is a cut end view of the guide portion (outer rail portion 31) and the guide portion reinforcing member 550 in the above.

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

The opposite surface side projecting portion 551 is coupled to the contact portion 552 and the contact portion 552 thereof, which are in contact with 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. It also includes an inclined portion 553 that inclines downward from the top portion toward the outward side in the axial direction of the fitting convex portion 55. The inclined portion 553 is provided so as to offset the fitting convex portion 55 radially outward with the fitting convex portion 55 as the center of rotation with respect to the fitting convex portion 55. Further, the inclined portion 553 is formed so that the distance from the contact portion 552 increases in the front view as the distance from the fitting convex portion 55 increases. In other words, the inclined portion 553 is formed so 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 mounting the guide portion reinforcing member 550 and the outer rail portion 31 on 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) shows the guide portion (outer rail portion 31) and the guide portion reinforcing member 550 fixed. It is a partially enlarged front view of the game board 530 which shows the state of doing. In FIG. 36A, the position of the outer rail portion 31 arranged on the game board 530 is shown by a two-dot chain line.

As shown in FIG. 36A, when the guide portion reinforcing member 550 and the outer rail portion 31 are arranged on the board surface 530a of the game board 530, first, the fitting convex portion 55 of the guide portion reinforcing member 550 is played. It is temporarily placed by inserting it into the hole 69 of the board 530 to a length of about half. In the case of temporary arrangement, the position of the inclined portion 553 is overlapped with the position where the outer rail portion 31 is arranged (two-dot chain line) in front view.

Next, as shown in FIG. 36 (b), in order to arrange the outer rail portion 31, the side edge of the outer rail portion 31 (the back edge of the paper surface in FIG. 36 (b)) is abutted against the inclined portion 553 and is placed on the board surface 530a. Get closer. Since the inclined portion 553 is provided so as to be offset radially outward with respect to the fitting convex portion 55 centered on the hole portion 69, as the outer rail portion 31 is brought closer to the board surface 530a, the inclined portion 553 is provided so as to be offset radially outward. 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 edge of the paper surface in FIG. 36B) is separated from the inclined portion 553, the rotation of the guide portion reinforcing member 550 is stopped, and the position of the guide portion reinforcing member 550 is determined.

Further, when the outer rail portion 31 is brought closer 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 projecting portion 57. When the outer rail portion 31 is further brought closer to the board surface 530a in this state, the base end side end surface (bottom surface of the groove portion 58) of the fitting convex portion 55 is pushed against the side edge of the outer rail portion 31, and the fitting convex portion 55 becomes It is gradually fitted into the hole 69. As a result, the workability of the arrangement work of arranging the outer rail portion 31 on the board surface 530a of the game board 530 can be improved.

In this way, the fitting convex portion exerts a force that brings the outer rail portion 31 closer to the board surface 530a by the inclined portion 553 provided so as to offset the fitting convex portion 55 that is the center of rotation outward in the radial direction. It can be converted into a force that rotates the guide portion reinforcing member 550 around 55. As a result, 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 it before arranging the outer rail portion 31, the position of the inclined portion 553 is set to the outer rail. It suffices to overlap with the position where the part 31 is arranged. Therefore, the accuracy of the alignment of the guide portion reinforcing member 550 (the angle alignment of the contact portion 552 with respect to the fitting convex portion 55 which is the center of rotation) in the temporarily arranging work can be made almost unnecessary. 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 their placement work can be improved.

Further, the inclined portion 553 is formed so that the distance from the contact portion 552 increases in the front view as the distance from the fitting convex portion 55 increases. That is, the inclined portion 553 is formed so that the width of the fitting convex portion 55 side is narrowed in the front view, while the width is widened as the distance from the fitting convex portion 55 is increased. As a result, the width of the inclined portion 553 on the side opposite to the fitting convex portion 55 can be increased by the amount that the guide portion reinforcing member 550 is temporarily arranged on the game board 530. The accuracy of the angle adjustment of the contact portion 552 with respect to 55) can be reduced. As a result, the time required for positioning the work of temporarily arranging the guide portion reinforcing member 550 on the game board 530 can be shortened, and the arranging work of the outer rail portion 31 and the guide portion reinforcing member 550 can be made more efficient.

There is a pachinko machine as a typical example of a game machine that plays a game using a game ball. The pachinko machine has a game board in which a game area is formed on the front surface. The game area is provided with a ball entry section where a game ball can enter, and when a ball enters the entry section, for example, whether or not to generate a special gaming state advantageous to the player. Benefits such as lottery and payout of game balls will be given to the players.
In this type of game machine, the conventional game board is generally one in which a synthetic resin film on which a pattern is printed is attached to the surface of wooden plywood (veneer). In recent years, a game board made of synthetic resin has been adopted from the viewpoint of designability and recyclability (for example, Patent Document 1: Japanese Patent Application Laid-Open No. 10-11342 (particularly FIG. 5)).
In such pachinko machines, it is common that a game board is detachably attached to the main body of the pachinko machine so that the game board can be replaced with respect to the main body of the pachinko machine as needed, such as when changing models. Therefore, in general, the game board is produced through a manufacturing process separate from the pachinko machine main body. In the manufacturing process of the synthetic resin game board, first, nails (obstacle nails) are planted on the board material for the synthetic resin game board. After that, small parts such as a wind turbine and rail members (guidance rails) are attached to the plate material, and then large parts such as a large winning device and a control circuit board are assembled. Assembling large parts complicates the work and reduces the process capability. Due to the imbalance of process capability, the game board in the middle of manufacturing may temporarily stay between processes. In such a case, in order to make the stagnant game boards stand by, the game boards in the process of being manufactured may be temporarily stacked.
