They are attached to the surface of the game board 30 by screwing screws into prepared holes (screw insertion holes) drilled by a drill or the like.

In this embodiment, the variable display unit 43 is arranged substantially in the center of the game board 30, a through chucker (starting opening) 36 is arranged below it, and a winning opening 37 is arranged below it. A through gate 34 is arranged on the right side of the variable display unit 43, and a plurality of general prize winning openings 38 are arranged on both sides of the lower portion of the game board 30, respectively. The prize-winning port 37 is additionally provided with an electric accessory that is in an operating state (open state) under a predetermined condition.

When a game ball enters the variable prize winning device 35, the prize winning port 37 and the general prize winning port 38, it is detected by a detection switch (not shown), and based on the detection result, the upper tray 6 (or the lower tray 8 in some cases). A predetermined number of prize balls are paid out to In addition, an out port 39 is provided at the bottom of the game board 30, and game balls that do not enter various winning ports are guided to a ball discharge path (not shown) through the out port 39. The out port 39 is formed through the thickness direction of the game board 30 when the game board 30 is molded due to the design of the mold.

Also, the variable display unit 43 is provided with a symbol display device 43a that variably displays symbols triggered by the winning of the starting port 36. FIG. The pattern display device 43a is constructed as a liquid crystal display device having a relatively large 8-inch liquid crystal display, and the display contents are controlled by a display control device. On the pattern display device 43a, for example, patterns are displayed side by side on the left, middle and right, and these patterns are variably displayed by being scrolled vertically. The pattern display device 43a has a liquid crystal display of 10 inches, 7 inches, etc., other than 8 inches, a wide size display, or a display screen of other types such as CRT, dot matrix, 7 segments, etc. may be configured. A center frame 47 is arranged so as to surround the pattern display device 43a.

The center frame 47 has a frame shape penetrating in the front-rear direction, and various decorations are provided on the front surface thereof. The center frame 47 surrounds the pattern display device 43a to prevent the game ball from entering the opening 61 to which the variable display unit 43 is mounted, and also to prevent the game ball from entering the center frame 47 from the board surface of the game board 30. It has a function to derive again to the board surface.

In addition, the game board 30 is provided with a large number of nails for properly dispersing and adjusting the falling direction of the game balls, and various members (accessories) such as windmills (not shown). ing. The nails and pinwheels are attached to the game board 30 by drilling pilot holes (nail insertion holes) in the game board 30 with a drill or the like and driving them into the pilot holes. This is to prevent the game board 30 from cracking due to hammering of nails or pinwheels.

A guide portion reinforcing member 50 for reinforcing the outer rail portion 31 (a game ball guide portion) is fixed to the outside of the outer rail portion 31 (on the side opposite to the inner rail portion 32). The configuration of the guide portion reinforcing member 50 will be described later. Protruding pins 60 are erected at two diagonal positions near the periphery of the game board 30 .

A light-transmitting synthetic resin film is attached to the surface of the game board 30 . The film is formed with a plurality of printed portions that are colored by printing. The plurality of printed portions are provided with a difference in translucency, and an opaque portion having no translucency is also provided. As a result, when the game board 30 is irradiated with light from the back side of the game board 30, light and darkness are generated in the printed part due to the difference in translucency of the printed part, so that the performance effect can be enhanced.

Next, the game board 30 will be described with reference to FIGS. 6 and 7. FIG. 6 is a front view of the game board 30, and FIG. 7 is a rear view of the game board 30. As shown in FIG. FIGS. 6 and 7 show a state before the game board 30 is provided with pilot holes (screw insertion holes) into which screws or the like are screwed and pilot holes (nail insertion holes) into which nails or pinwheels are driven. ing.

As shown in FIG. 6, openings 61 to 67 and holes 68 and 69 are formed through the game board 30 in the thickness direction. The opening 61 is a through hole to which the variable display unit 43 and the center frame 47 are attached, and the opening 62 is a through hole to which the protruding pin 60 is attached. The opening 63 is a through hole to which the through gate 34 is attached, and the opening 64 is a through hole to which the variable winning device 35 and the general winning opening 38 are attached. The opening 65 is a through hole to which a through chucker (starting opening) 36 is attached, the opening 66 is a through hole to which a winning opening 37 is attached, and the opening 67 is a through hole to which a general winning opening 38 is attached. through-holes.

The hole portion 68 is a through hole into which a fitting pin (to be described later) spot-welded to the outer rail portion 31 and the inner rail portion 32 is inserted. They are scattered at predetermined intervals on a substantially circular curve. The hole portion 69 is a through-hole into which the guide portion reinforcing member 50 is mounted, and is formed through the hole portion 69 at a lower position on the left side of the left and right center when the game board 30 is viewed from the front. Since the holes 68 and 69 have a small inner diameter (hole diameter), they are drilled with a drill or the like after the game board 30 is molded.

As shown in FIG. 7, the game board 30 has a thick portion 70 which is positioned substantially in the center of the back surface of the game board 30 and has a substantially circular outer shape when viewed from the rear, and a thick portion 70 formed around the thick portion 70 . An inclined surface portion 71 having an approximately circular outer shape in rear view, a thin portion 72 formed around the inclined surface portion 71 and having an approximately rectangular outer shape in rear view, and a periphery of the thin portion 72 It is integrally formed with a peripheral edge reinforcing rib 73 erected on the .

Next, referring to FIG. 8, the cross-sectional shape of the game board 30 will be described. FIG. 8 is a cut end view of the game board 30 taken along line VIII-VIII of FIG. As shown in FIG. 8, the game board 30 has a flat surface on the board surface side (front side, lower side in FIG. 8), and a thick portion 70 is formed on the back side (upper side in FIG. 8) and has a thickness of It is set approximately constant. The inclined surface portion 71 is connected to the thick portion 70 and is formed such that the thickness of the inclined surface portion 71 gradually decreases toward the periphery of the game board 30 (toward the outer periphery). The thin portion 72 is continuous around the inclined surface portion 71 and has a thickness smaller than that of the thick portion 70 . The outer peripheral edge reinforcing rib 73 is a part for improving the rigidity of the thin portion 72 , is continuously provided around the thin portion 72 , and protrudes from the outer peripheral edge of the thin portion 72 toward the rear side. In addition, since the height of the outer peripheral edge reinforcing rib 73 (in the vertical direction in FIG. 8) is set to a value larger than the thickness of the thick portion 70, the game board 30 is attached to 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 side end portion of the peripheral edge reinforcing rib 73 is brought into contact with the front surface of the resin base 20 .

Returning to FIG. 7, description will be made. The thick part 70 is positioned substantially in the center of the back side of the game board 30, and a game area PE is formed on the front side of the thick part 70. As shown in FIG. Since a nail that interferes with a game ball is planted in the game area PE, a thick part 70 is formed in a substantially central portion of the game board 30 on which the game area PE is formed to secure the board thickness. It is possible to secure the holding power of the nail implanted in the portion 70 .

In addition, since the thickness of the thick 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 thickness. It can be lighter than a board. Since the thickness of the thick portion 70 is set to be smaller than the height of the outer peripheral edge reinforcing rib 73, a space can be provided on the back side of the thick portion 70, so decorations or the like can be arranged in the space on the back side. It becomes possible to Since it is also possible to dispose a light-emitting element such as an LED in the space on the back side, the production effect can be improved.

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

Further, since the outer peripheral edge reinforcing rib 73 is erected on the outer peripheral edge of the thin portion 72, the rigidity of the thin portion 72 can be improved, and deformation such as warping of the thick portion 70 and the thin portion 72 can be prevented. Thereby, 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 connected to the thin portion 72 so that the thickness of the inclined surface portion 71 gradually decreases toward the outside from the thick portion 70 . As a result, when the game board 30 is molded, it is possible to suppress deformation due to the difference in thickness between the thick portion 70 and the thin portion 72 . That is, the game board 30 is molded by filling a cavity of a molding die with molten synthetic resin, and after hardening, the molding is removed from the molding die. Since the cooling speed of the compact is faster for the thin portion 72 with a smaller thickness than for the thick portion 70 with a larger thickness, residual stress is generated due to the difference in cooling speed, and the game board 30 tends to warp or otherwise deform. However, the slanted surface portion 71 connected between the thin portion 72 and the thick portion 70 can buffer the generation of residual stress due to the difference in cooling rate. As a result, deformation such as warping of the game board 30 can be prevented.

A hole portion 68 formed at the boundary between the thick portion 70 and the inclined surface portion 71 is a portion into which a fitting pin (described later) spot-welded to the inner rail portion 32 is inserted. Positioned on the outer peripheral side of the game board 30 from the boundary between the thick portion 70 and the inclined surface portion 71, the holes 68 formed in the thin portion 72 and the peripheral edge reinforcing ribs 73 are fitted to the outer rail portion 31 by spot welding. This is a portion into which a dowel pin (to be described later) is inserted. The hole 68 has a cylindrical protrusion 68a that rises from the periphery of the hole 68 toward the rear 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, since the load per unit area applied by the fitting pin to the inner periphery of the hole 68 can be reduced, cracks are less likely to occur around the hole 68 (in particular, the thin portion 72). In addition, since the depth of the hole 68 (in the front-rear direction of the game board 30) can be increased by the projecting portion 68a, the holding force of the fitting pin can be increased. Thereby, the outer rail portion 31 and the inner rail portion 32 can be firmly fixed to the board surface of the game board 30 .

A protruding portion 68a (hole portion 68) into which a 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. A portion 70 and an inclined surface portion 71 are continuously provided. Since the plate thicknesses of the thick portion 70 and the inclined surface portion 71 are larger than the plate thickness of the thin portion 72, the projecting length of the projecting portion 68a with respect to the thick portion 70 and the inclined surface portion 71 is larger than the projecting length of the projecting portion 68a with respect to the thin portion 72. can be made smaller. As a result, the bending moment of the projecting 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 projecting portion 68a with respect to the thin portion 72. The bending strength of 68a can be improved more than the bending strength of the projecting portion 68a protruding from the thin portion 72. As shown in FIG.

In addition, a fitting pin spot-welded to the inner rail portion 32 is inserted into a hole portion 68 formed in a projecting portion 68 a 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 a holding force for nails, pinwheels, and the like. A projecting portion 68a (hole 68) into which a fitting pin spot-welded to the inner rail portion 32 is inserted is provided at the boundary between the thick portion 70 and the inclined surface portion 71, so that the area of the thick portion 70 is excessive. can be prevented from increasing to By not expanding the thick portion 70 outside the area (inside the inner rail portion 32) where the game area PE is formed, the amount of synthetic resin forming the game board 30 is reduced, and the mass of the game board 30 is reduced. 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 portion of the game board 30 and the inclined surface portion 71 and penetrates the game board 30 in the thickness direction. A reinforcing rib 39 a is erected around the out port 39 toward the rear side, and the reinforcing rib 39 a is formed integrally with the game board 30 . The reinforcing rib 39a constitutes a passage for a 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 rigidity.

The hole portion 69 is a portion into which a fitting protrusion (described later) of the guide portion reinforcing member 50 is inserted, and is formed so as to pass 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, since the load per unit area applied to the inner periphery of the hole 69 by the fitting protrusion can be reduced, cracks are less likely to occur around the hole 69 (thin portion 72). In addition, 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 protrusion 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 recessed portions 73a, 73b, and 73c (the height of the rib is lowered) in which part of the end face on the back side (the front side of the paper surface of FIG. 7) is recessed in the height direction. . The recessed portions 73a and 73c are formed at opposing positions of 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) in which the recessed portions 73a and 73c are formed. It is formed in the outer peripheral edge reinforcing rib 73 (lower rib). Since recessed portions 73a and 73c are formed at positions facing the outer peripheral edge reinforcing ribs 73, the molded game board 30 is placed on a platform having a flat upper surface with the outer peripheral edge reinforcing ribs 73 facing downward. When the game board is placed on its back side (with the back side facing downward), a gap corresponding to the depressions 73a and 73c is formed between the flat surface and the game board 30 (peripheral edge reinforcement rib 73). A fingertip or the like of a hand is inserted into the gap, and the game board 30 placed on a flat surface can be lifted by using the inserted fingertip or the like as a handhold.

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

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

The heights of the reinforcing ribs 39a, 62a and the protruding portions 68a, 69a are set substantially equal to the height of the peripheral reinforcing rib 73. As shown in FIG. As a result, the board surface of the game board 30 ( When a load is applied to the front surface), the load can be received by the reinforcing ribs 39a, 62a, the protrusions 68a, 69a, and the peripheral edge reinforcing rib 73.

On the other hand, if the reinforcing ribs 39a, 62a and the projecting portions 68a, 69a are not formed, the thick portion 70 and the thin portion 72 are bent and deformed when the game board 30 receives a load on the board surface. If the deformation becomes large, cracks may occur near the boundary between the peripheral edge reinforcing rib 73 and the thin portion 72 . According to this embodiment, 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 edge reinforcing rib 73, so that the thick portion 70 and the thin portion 70 can be separated from each other by the load applied to the board surface. This problem can be solved because the occurrence of bending deformation in the portion 72 can be suppressed.

In particular, the projecting portions 68a for fixing the outer rail portion 31 and the inner rail portion 32 are positioned on a substantially semi-circular line and widely scattered on the game board 30. Even when a concentrated load is applied to the surface of the game board 30, it is possible to prevent the board surface of the game board 30 from undergoing a large bending deformation. As a result, the game board 30 can be prevented from being damaged by the load applied to the game board 30 when a nail is implanted in the game board 30 or various game parts are attached.

Next, referring to FIG. 9, the opening 62 and the projecting pin 60 will be described. FIG. 9 is a cut end view of the game board 30 taken along line IX-IX in FIG. As shown in FIG. 9, the protruding pin 60 is a substantially cylindrical member configured separately from the game board 30, and includes a flange portion 60a protruding radially (horizontally in FIG. 9) from the outer peripheral surface, A fitting portion 60b extending from the collar portion 60a to the other side in the axial direction is continuously provided. The fitting portion 60b is a portion that is fitted into the opening portion 62, and the collar portion 60a is a portion that regulates the insertion depth of the fitting portion 60b that is fitted into the opening portion 62. As shown in FIG. On the other hand, the board surface of the game board 30 is formed with a concave portion 62b for receiving the collar portion 60a. The recessed portion 62b is continuously provided around the opening 62 to a depth substantially equal to the thickness of the flange portion 60a. The diameter of the protruding pin 60 is slightly smaller than the diameter of the insertion portion 60b (the inner diameter of the opening 62).

The reinforcing rib 62 a has a rear end face (lower side in FIG. 9 ) set at substantially the same height as the end face of the peripheral edge reinforcing rib 73 on the rear side (lower side in FIG. 9 ). As a result, the depth of the opening 62 (vertical direction in FIG. 9) can be increased, so that the insertion depth of the insertion portion 60b 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. As shown in FIG. In this case, the holding force for holding the fitting portion 60b in the opening portion 62 becomes smaller than in the present embodiment, and the protruding pin 60 becomes loose or easily comes off. By providing the reinforcing ribs 62a as in the present embodiment, this can be prevented.

In addition, since the game board 30 having the fitting portion 60b inserted into the opening 62 has the collar portion 60a, the protruding pin 60 protrudes from the board surface of the game board 30 by a predetermined length. On the other hand, the reinforcing rib 62a is formed with a recess (hole) deeper than the protruding length of the protruding pin 60 from the board surface on the rear side (lower side in FIG. 9). Since the diameter of the protruding pin 60 is formed slightly smaller than the diameter of the insertion portion 60b (the inner diameter of the opening 62), when a plurality of game boards 30 are stacked, one game board 30 can be projected from the board surface. The projected projecting pin 60 is inserted from the back side of the other game board 30 into the depression (hole) in the reinforcing rib 62a. As a result, it is possible to prevent the game boards 30 stacked in a flat state from being displaced in the direction of the board surface.

By configuring the projecting pin 60 as a separate member from the game board 30 as in the present embodiment, after the game board 30 is molded, until the projecting pin 60 is fitted into the opening 62, the game board The protruding pin 60 can be prevented from protruding from the board surface of 30.例文帳に追加This prevents the projecting pin 60 from interfering with the transportation of the game board 30 or from being damaged until the projecting pin 60 is fitted into the opening 62 after the game board 30 is molded. can. After fitting the projecting pin 60 into the opening 62, the projecting pin 60 can be removed from the opening 62 if the projecting pin 60 is no longer needed when assembling the pachinko machine 1 or the like. As a result, the pachinko machine 1 can be assembled smoothly.

Further, when molding the game board 30, it is possible to form the protruding pins integrally with the game board. When fitting (inserting) the projecting pin 60 into the game board 30 as in the present embodiment, it is necessary to prepare the projecting pin 60 as a separate member and insert the projecting pin 60 into the game board 30 . On the other hand, by integrally forming the projecting pin with the game board, it is possible to eliminate the need to prepare the projecting pin 60 as a separate member, thereby reducing the number of parts. Also, the work of inserting the protruding pin 60 into the game board 30 can be eliminated.

FIG. 10 is a schematic diagram showing a state in which a plurality of game boards 30 are stacked. The game board 30 is integrally formed by melting and filling a molding die with a synthetic resin, and an outer peripheral edge reinforcing rib 73 is erected on the rear side of the flat board surface (front surface). When the synthetic resin game board 30 is stacked and transported, there arises a problem that the position of the synthetic resin game board 30 shifts and slips easily compared to the case where the conventional wooden plywood game board is stacked and transported. This is because the synthetic resin game board 30 is more slippery than the wooden plywood game board because the surface smoothness of the board surface is high and the coefficient of friction is small.

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 recesses (holes) in the reinforcing ribs 62a of the other game board 30. Can be easily transported. In addition, since it is easy to insert a fingertip or the like 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. In addition, since the recessed portions 73a and 73c are formed at positions facing the outer peripheral edge reinforcing rib 73, the fingertips of the left and right hands can be inserted into the recessed portions 73a and 73c to lift the object in a well-balanced manner. Furthermore, since the recessed portion 73b is formed in the outer peripheral edge reinforcing rib 73 (located at the bottom in FIG. 7) that intersects the outer peripheral edge reinforcing rib 73 (located on the left and right in FIG. 7) in which the recessed portions 73a and 73c are formed. , the game board 30 can be supported from three sides, and the game board 30 can be transported in good balance.

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 the guide portion reinforcing member 50. is a perspective view of the. The guide portion reinforcing member 50 is a member for preventing the outer rail portion 31 on which the game ball launched from the game ball launching device 21 first collides from swinging. By attaching 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. 11 . The outer rail portion 31 is formed of a strip-shaped metal (made of stainless steel) thin plate, and fitting pins 31a are spot-welded to the longitudinal side edges of the outer rail portion 31 at appropriate intervals. The outer rail portion 31 is erected on the game board 30 by fitting the fitting pin 31 a into the hole 68 formed in the game board 30 .

In addition, the outer rail portion 31 includes a bent portion 31b in which the longitudinal edge is bent and folded back into a substantially U shape. The bent portion 31b is a portion for preventing the longitudinal edge of the outer rail portion 31 from swinging, and guides the outer rail portion 31 through which the game ball fired from the game ball launching device 21 is guided. It is bent to the opposite surface side (rear surface side) of the surface 31c. As a result, when the game ball shot 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 side) of the guide surface 31c. can be prevented.

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. As shown in FIG. That is, the guide portion reinforcing member 50 is arranged between the fitting pins 31a. Since the fitting pins 31a are fixed to the outer rail portion 31 with an appropriate space therebetween, the outer rail portion 31 can easily swing between the fitting pins 31a. However, by arranging the guide portion reinforcing member 50 between the fitting pins 31a, it is possible to suppress the outer rail portion 31 from swinging between the fitting pins 31a.

Next, a 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 formed in a substantially trapezoidal shape when viewed from the front (as viewed from the board surface side of the game board 30), and is opposite to the guide surface 31c of the outer rail portion 31. A base portion 51 positioned on the surface side, an opposite surface side projecting portion 52 erected from the base portion 51, and a projection from the base portion 51 in the direction opposite to the direction in which the opposite surface side projecting portion 52 is erected. It is mainly provided with the fitting convex part 55 protrudingly provided.

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

The opposite surface side projecting portion 52 includes an inclined portion 52a that slopes downward from the top toward the base portion 51 side (board surface side), and an inclined portion 52a that is continuous with the inclined portion 52a and faces the outer rail portion 31 at least one side. and a contact portion 52b with which the portion contacts. A fitting convex portion 55 is projected from one side edge of the base portion 51 and the projecting portion 52 on the opposite surface side. A rod-like columnar portion 53 is erected along the opposite surface side projecting portion 52 on the other side edge of the base portion 51 and the opposite surface side projecting portion 52 facing one side edge. 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 positioned on the back side of the contact portion 52b. As a result, bending deformation of the opposite surface side projecting portion 52 with respect to the axial direction of the columnar portion 53 can be made less likely to occur, as compared with a case in which the columnar portion 53 is not formed.

In the present embodiment, the columnar portion 53 is formed in a cylindrical shape with a hole (vertical hole portion 53a) formed substantially in the center along the axis of the columnar portion 53 . By making the columnar portion 53 cylindrical with the vertical hole portion 53a, the torsional rigidity is improved compared to a solid columnar portion (with the same outer diameter) without the vertical hole portion 53a. In addition, the weight of the columnar portion 53 can be reduced. As a result, the torsional rigidity of the opposite-surface-side projecting portion 52 is improved (difficult to deform) and the mass is excessively increased compared to the case where the columnar portion is solid without the vertical hole portion 53a. can be prevented.

The columnar portion 53 has a substantially triangular reinforcing portion 54 extending in the axial direction of the outer peripheral edge. The reinforcement part 54 is a member for reinforcing the columnar part 53, and is set so that the cross-sectional area gradually increases from the top side to the bottom side, and the bottom part is set so as to be in close contact with the board surface of the game board 30. be. A substantially triangular reinforcing part 54 is extended to the columnar part 53, and the bottom part of the columnar part 53 is set so as to be in close contact with the board surface of the game board 30, so that the columnar part 53 can be made more difficult to bend and deform.

The length of one side edge of the base portion 51 from which the fitting convex portion 55 protrudes is set to be 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 to the other side edge of the base portion 51. is set to be By making the bottom area of the base portion 51 farther from the fitting convex portion 55 larger than the bottom area of the base portion 51 at the position close to the fitting convex portion 55, the bottom of the position far from the fitting convex portion 55 is made larger. It can prevent area shortage. As a result, it is possible to suppress the swinging of the opposite surface side projecting portion 52 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, the base portion 51 is positioned relative to the position of the axis of the fitting convex portion 55 as shown in FIG. can be shifted toward the end portion (bent portion 31b) of the outer rail portion 31 . As a result, the position of the fitting pin 31a that fixes the outer rail portion 31 to the game board 30 can be brought closer to the position of the opposite surface side projecting portion 52 (contact portion 52b). By bringing the contact portion 52b closer to the fitting pin 31a that fixes the outer rail portion 31, the outer rail portion 31 can be made difficult to bend between the fitting pin 31a and the contact portion 52b. As a result, the guide portion reinforcing member 50 can effectively reinforce the outer rail portion 31 .

The fitting convex portion 55 is a portion that is fitted into a hole portion 69 formed in the game board 30 in order to fix the guide portion reinforcing member 50 to the game board 30. It is formed in a columnar shape. The fitting convex portion 55 has a rounded reduced diameter portion 55a formed at the tip. The reduced-diameter portion 55a is a portion that is set so that the area of the cross section perpendicular to the axis gradually decreases toward the distal end side. Since the diameter-reduced portion 55 a is formed, the fitting protrusion 55 can be easily fitted into the hole portion 69 . Further, since the fitting convex portion 55 and the hole portion 69 are formed to have a substantially circular cross section, fine position adjustment when inserting the guide portion reinforcing member 50 into the hole portion 69 can be omitted. As a result, the workability 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. 12 . FIG. 12 is a partially enlarged rear view of the game board 30 on which the guide portion (the outer rail portion 31) and the guide portion reinforcing member 50 are installed. In FIG. 12, the position of the outer rail portion 31 arranged on the board surface of the game board 30 is indicated by imaginary lines (double-dot chain lines).

As shown in FIG. 12, the fitting convex portion 55 has a concave portion 56 formed in a concave shape on a part of the outer peripheral surface. Since a part of the outer peripheral surface of the fitting projection 55 is formed in a concave shape by the recess 56 , when the fitting projection 55 is fitted into the hole 69 , the outer peripheral surface of the fitting projection 55 and the hole 69 are aligned. The contact area with the inner peripheral surface of the can be reduced. As a result, the vertical force per unit area of the hole portion 69 and the fitting projection portion 55 when fitting the fitting projection portion 55 into the hole portion 69 can be increased. As a result, the hole portion 69 or the fitting projection portion 55 can be easily deformed (elastic deformation or plastic deformation) when fitting the fitting projection portion 55 into the hole portion 69. It can be easily fitted into 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 . Furthermore, since the concave portion 56 is formed from the distal end to the proximal end of the fitting convex portion 55 , the effect of the concave portion 56 can be obtained from the distal end to the proximal end of the fitting convex portion 55 .

In the present embodiment, the concave portion 56 is formed in a slot shape from the distal end of the fitting convex portion 55 toward the proximal end. As a result, the fitting convex portion 55 can be fitted into the hole portion 69 by utilizing the elastic deformation of the fitting convex portion 55 due to the slot. This makes it easier to fit the fitting protrusion 55 into the hole 69 . Furthermore, by utilizing the elastic deformation of the fitting convex portion 55 , it is possible to prevent the gap from being generated between the hole portion 69 and the fitting convex portion 55 . As a result, the fitting protrusion 55 fitted in the hole 69 is less likely to rattle.

Furthermore, in the present embodiment, the direction of the slot of the concave portion 56 seen from the axial direction of the fitting convex portion 55 (perpendicular to the paper surface of 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 advancing toward the game area PE along the guide surface 31c of the belt-shaped outer rail portion 31, the fitting convex The elastic deformation of the portion 55 can be made difficult. This makes it difficult to tilt the guide portion reinforcing member 50 .

That is, the fitting convex portion 55 is difficult to be elastically deformed by a load parallel to the direction of the slot, and is likely to be elastically deformed by a load perpendicular to the direction of the slot. This is because when a load parallel to the direction of the slot is applied to the fitting convex portion 55, the fitting convex portion 55 is deformed so as to reduce the gap of the slit-shaped concave portion 56. FIG. Therefore, if the guiding portion reinforcing member 50 is arranged so that the slotted direction of the fitting convex portion 55 is parallel to the longitudinal direction of the outer rail portion 31, the guiding surface 31c of the outer rail portion 31 is pushed to the opposite 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 guiding portion reinforcing member 50 is arranged so that the direction of the slot of the fitting convex portion 55 is not parallel to the longitudinal direction of the outer rail portion 31, the guiding surface 31c of the outer rail portion 31 becomes the opposite surface. The elastic deformation of the fitting convex portion 55 can be made difficult when pushed to the side. This makes it difficult to tilt the guide portion reinforcing member 50 .

In particular, by making the longitudinal direction of the outer rail portion 31 perpendicular to the slotted direction of the recessed portion 56, it is possible to make elastic deformation of the fitting convex portion 55 most difficult due to a load parallel to the slotted direction. Accordingly, it is possible to prevent the guide portion reinforcing member 50 from tilting together with the tilting of the outer rail portion 31 . As a result, the tilting of the outer rail portion 31 as the game ball advances can be suppressed, and the trajectory and flight distance of the game ball traveling along the outer rail portion 31 can be stabilized.

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

In addition, a cutout portion 56a having a substantially circular cross section is formed in the fitting convex portion 55 along the axis (perpendicular to the paper surface of FIG. 12) substantially in the center of the fitting convex portion 55. ing. Since the cutout portion 56a is formed, the cross-sectional area of the approximate center (near the axis line) of the fitting convex portion 55 can be reduced. As a result, the cross-sectional shape of the fitting protrusions 55 on both sides of the recess 56 when viewed in the axial direction can be substantially fan-shaped. As a result, when a load parallel to the direction of the slot is applied to the fitting convex portion 55, the fitting convex portion 55 can be deformed so as to reduce the cross-sectional area of the recessed portion 56a. Thereby, the fitting convex portion 55 can be fitted into the hole portion 69 by utilizing the elastic deformation of the fitting convex portion 55 by the recessed cutout portion 56a. This makes it easier to fit the fitting protrusion 55 into the hole 69 .

Since the amount of elastic deformation of the fitting convex portion 55 by the concave/cut portion 56a is smaller than the amount of elastic deformation of the fitting convex portion 55 by the concave portion 56, the fitting convex portion in the direction of the slot (approximately vertical direction in FIG. 12) The amount of elastic deformation of 55 can be made different from the amount of elastic deformation of fitting projection 55 in the direction orthogonal to the slot (substantially left-right direction in FIG. 12). Specifically, the amount of elastic deformation of the fitting convex portion 55 in the direction of the slot (generally vertical direction in FIG. 12) is calculated as It can be smaller than the quantity. Therefore, it is possible to prevent the effect of making it difficult to tilt the guide portion reinforcing member 50 when the recessed portion 56a is formed.

The end surface of the projecting portion 68a into which the fitting pin 31a fixed to the outer rail portion 31 is inserted is recessed from the hole portion 68 (inner peripheral surface) to the outer peripheral surface. An end face groove portion 68b is formed. The end face groove portion 68b is formed along the longitudinal direction of the outer rail portion 31 arranged on the board surface of the game board 30. As shown in FIG. Since the end surface groove portion 68b is formed on the end surface of the protruding portion 68a, it is difficult to make a mistake in the direction of arranging the outer rail portion 31 when arranging the outer rail portion 31 on the game board 30. - 特許庁

Returning to FIG. 11, description will be made. As shown in FIG. 11, the guide portion reinforcing member 50 is disposed on the guide surface 31c side of the outer rail portion 31 so as to face the opposite surface side projecting portion 52, and is a guide surface projecting portion contacting the guide surface 31c. A portion 57 is provided. As shown in FIGS. 11 and 13 , the guide surface-side protruding portion 57 protrudes from a portion of the fitting protruding portion 55 in the axial direction on the base end side (the front side of the paper surface of FIG. 11 ). A groove portion 58 into which the outer rail portion 31 is inserted is formed between the guide surface side projecting portion 57 and the opposite surface side projecting portion 52 .

Next, with reference to FIG. 14, the guide surface side projecting portion 57 and the groove portion 58 will be described. FIG. 14 is a sectional view of the game board 30 along line XIV-XIV in FIG. As shown in FIG. 14 , the guide-surface-side projecting portion 57 is arranged to face the opposite-surface-side projecting portion 52 with an interval substantially equal to the thickness of the outer rail portion 31 . The opposite surface side projecting portion 52 is set to have substantially the same height as the outer rail portion 31 , but the guide surface side projecting portion 57 is set lower than 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 has 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.

In addition, since the guide surface side projecting portion 57 disposed 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 is moved along the guide surface 31c. can be prevented from being obstructed by the guide surface side projecting portion 57.例文帳に追加If 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. , the flight distance of the game ball B guided to the game area PE can be prevented from becoming unstable.

In addition, as shown in FIG. 14, the concave portion 56 is formed in a slot shape from the tip of the fitting convex portion 55 (lower side in FIG. 14) while leaving the base end (base end portion 55b) of the solid fitting convex portion 55. formed. As a result, the base end portion 55b of the solid fitting convex portion 55 can be fitted into the hole portion 69 (board surface side). By fitting the base end portion 55b of the solid fitting projection 55 into the hole 69 (on the board surface side), the fitting projection 55 can be prevented from rattling with respect to the hole 69 . Furthermore, since the concave portion 56 is formed on the tip side of the fitting convex portion 55, the fitting convex portion 55 or the hole portion 69 can be easily elastically or plastically deformed, and the fitting convex portion 55 can be easily deformed into the hole portion. 69 can be easily fitted.

A gap between the outer peripheral surface of the fitting convex portion 55 (base end portion 55b) and the hole portion 69 is held by the groove portion 58 between the opposite surface side projecting portion 52 and the guide surface side projecting portion 57. It is set to a value smaller than the gap between the rail portion 31 and the opposite surface side projecting portion 52 or the guide surface side projecting portion 57 . While preventing rattling of the fitting convex portion 55 (base end portion 55b) inserted in the hole portion 69, when fixing the outer rail portion 31 to the game board 30, the opposite surface side projecting portion 52 and the guide This is for facilitating the insertion of the outer rail portion 31 into the groove portion 58 between the surface-side projecting portions 57 . Note that 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. The looseness of the outer rail portion 31 with respect to the game board 30 can be prevented.

As described above, the guide portion reinforcing member 50 for restricting the tilting of the outer rail portion 31 includes the fitting convex portion 55 that fits into the hole portion 69 formed in the board surface of the game board 30 and the fitting convex portion. An opposite-surface-side projecting portion 52 that protrudes from the portion 55 and contacts the opposite surface side of the guide surface 31c of the outer rail portion 31 is provided. The guide portion reinforcing member 50 has a projection portion on the opposite side of the game board 30. The projection portion 55 is fitted into a hole portion 69 formed in a recessed shape on the board surface of the game board 30, and the projection portion on the opposite side projects from the projection portion 55. 52 contacts the side opposite to the guide surface 31c of the outer rail portion 31 . As a result, it is possible to prevent the belt-shaped outer rail portion 31 from tilting outward due to the guide surface 31c being pushed to the opposite surface side by the game ball advancing toward the game area PE along the guide surface 31c. Since tilting 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 guided to the game area PE can be stabilized.

That is, when the guide surface 31c is pushed to the opposite surface side by the game ball advancing toward the game area PE along the guide surface 31c and the belt-shaped outer rail portion 31 is tilted, the trajectory of the game ball is changed or the game ball is tilted. loss of kinetic energy. 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, by arranging the guide portion reinforcing member 50 so that the opposite surface side projecting portion 52 is in contact with the opposite surface side of the guide surface 31c of the outer rail portion 31, the guide surface It is possible to suppress tilting of the outer rail portion 31 by a game ball traveling along the 31c toward the game area PE. As a result, the trajectory and flight distance of the game ball guided to the game area PE can be stabilized.

In addition, since the fitting protrusion 55 has a concave portion 56 in which a part of the outer peripheral surface is formed in a concave shape, the fitting protrusion 55 can be easily displaced when the fitting protrusion 55 is fitted into the hole 69 . The contact area between the outer peripheral surface and the inner peripheral surface of the hole portion 69 can be reduced. As a result, the vertical force per unit area of the hole portion 69 and the fitting projection portion 55 when fitting the fitting projection portion 55 into the hole portion 69 can be increased. As a result, the hole portion 69 or the fitting projection portion 55 can be easily deformed (elastic deformation or plastic deformation) when fitting the fitting projection portion 55 into the hole portion 69. It can be easily fitted into the hole 69 .

In addition, since the concave portion 56 is formed in a slot shape from the tip of the fitting convex portion 55 toward the proximal end (base end portion 55b), elastic deformation of the fitting convex portion 55 due to the slot is utilized to , 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 into the hole portion 69, and the elastic deformation of the fitting convex portion 55 is used to prevent a gap from being formed between the hole portion 69 and the fitting convex portion 55. Therefore, it is possible to prevent the fitting protrusion 55 fitted in the hole 69 from rattling.

In addition, since the direction of the slot of the concave portion 56 seen 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 guide surface 31c of the belt-shaped outer rail portion 31 can move along the guide surface 31c. When the guide surface 31c is pushed to the opposite surface side by a game ball advancing toward the game area PE, the fitting convex portion 55 can be made difficult to be elastically deformed. As a result, tilting of the outer rail portion 31 can be suppressed. 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 projecting portion 57 facing the opposite surface side projecting portion 52, the outer rail portion 31 is held from both the guide surface 31c and the opposite surface. 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. Furthermore, since the guide surface side projecting portion 57 is set lower than the opposing opposite surface side projecting portion 52, interference between the game ball along the guide surface 31c and the guide surface side projecting portion 57 is prevented. can.

The opposite surface side projecting portion 52 includes an inclined portion 52a that slopes down from the top portion toward the outside in the axial direction of the fitting convex portion 55, and the opposite surface of the outer rail portion 31 that is continuous with the inclined portion 52a. Since the contact portion 52b is provided so that at least a part of the opposite surface is in contact with 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 attached to the game board 30. Insert into hole 69 . Since the recessed portion 56 is formed in a slot shape in the fitting projection portion 55, when the fitting projection portion 55 is inserted into the hole portion 69 of the game board 30, the fitting projection portion 55 is adjusted so as to narrow the interval between the slotted recessed portions 56. transform. Therefore, the operation of inserting about half the length of the fitting protrusion 55 into the hole 69 of the game board 30 can be facilitated.

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 . The slanted portion 52a is slanted 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 connected to the slanted portion 52a. can be smoothly arranged on the contact portion 52b.

Further, while the outer rail portion 31 is accommodated 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 inserted into the hole portion 68. go. As the fitting pin 31 a is inserted into the hole 68 , the side edge of the outer rail portion 31 presses the proximal end surface of the fitting projection 55 , and the fitting projection 55 is gradually fitted into the hole 69 . . Thereby, the workability of the arrangement work for 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 shape, the base end portion 55b is fitted into the hole portion 69. As shown in FIG. This can prevent the fitting convex portion 55 from rattling in the hole portion 69 .

Also, a projecting portion 69a projects toward the rear side from the thin portion 72 of the game board 30, and a hole portion 69 is formed through the projecting portion 69a and the thin portion 72, so that the hole portion 69 is fitted. The fitting depth of the fitting protrusion 55 can be ensured. As the fitting depth of the fitting projection 55 fitted into the hole 69 increases, the fitting projection 55 fitted into the hole 69 tends to be less likely to swing in the direction perpendicular to the axial direction. Therefore, by securing the fitting depth of the fitting convex portion 55 fitted in the hole portion 69, the guiding portion reinforcing member 50 fixed to the game board 30 can be made difficult to swing. By making it difficult to swing the guide portion reinforcing member 50 fixed to the game board 30, it is possible to suppress the tilting of the outer rail portion 31 that guides the game ball to the game area PE, so that the game ball is guided to the game area PE. The trajectory and flight distance of can be further stabilized.

In addition, since the projecting portion 69a is connected to the thin portion 72 and the hole portion 69 is formed through the projecting portion 69a and the thin portion 72, it is possible to increase the area of the thick portion 70 in order to form the hole portion 69. can be made unnecessary. Although the mass of the game board 30 increases by the amount of the projecting portion 69a (excluding the hole portion 69) connected to the thin portion 72, there is no need to increase the area of the thick portion 70, so the mass of the game board 30 can be reduced. increase can be suppressed. Furthermore, since the projecting portion 69a through which the hole portion 69 is formed functions as a rib that enhances 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 nail is implanted in the thick portion 70 to secure the holding power of the nail, and the rigidity of the game board 30 can be secured while the weight of the game board 30 can be reduced. In addition, the trajectory and flight distance of the game ball guided to the game area PE can be further stabilized.

Next, referring to FIG. 15, a guide portion reinforcing member 50 in another embodiment will be described. The same reference numerals are given to the same parts as in the first embodiment, and the following description is omitted. FIG. 15(a) is a partially enlarged rear view of a game board 30 on which a guide portion reinforcing member 80 is installed in another embodiment, and FIG. 15(b) is a game board on which a guide portion reinforcing member 90 is installed in another embodiment. 3 is a partially enlarged rear view of the board 30; FIG. 15(a) and 15(b), the fitting protrusions 85 and 95 of the guide reinforcing members 80 and 90 are fitted into the holes 69 formed in the game board 30 from the board surface (front) side. , and the state seen from the back side of the game board 30 is illustrated.

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

Further, a recessed portion 85 a having a circular cross section is formed substantially in the center of the fitting protrusion 85 from the tip of the fitting protrusion 85 along the axial direction of the fitting protrusion 85 . By reducing the cross-sectional area of the fitting protrusion 85 with the concave and cut portion 85a, the fitting protrusion 85 can be easily elastically deformed by the vertical force acting on the fitting protrusion 85. As shown in FIG. As a result, the fitting protrusion 85 can be fitted into the hole 69 more easily, and the workability of fitting the fitting protrusion 85 into the hole 69 can be improved. Further, by facilitating elastic deformation of the fitting protrusion 85 , it is possible to prevent the fitting protrusion 85 from rattling with respect to the hole 69 .

In particular, since the concave portion 86 is formed in such a shape that two portions are cut along the axial direction of the fitting convex portion 85, the outer peripheral surface of the fitting convex portion 85 is prevented from becoming excessively small. A contact area with the inner peripheral surface of the hole portion 69 can be ensured. Since it is possible to prevent the vertical force per unit area of the outer peripheral surface of the fitting protrusion 85 from becoming excessively large, deformation such as buckling of the outer peripheral surface of the fitting protrusion 85 can be suppressed. As a result, it is possible to prevent problems such as rattling of the fitting convex portion 85 caused by 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 provided at four axially symmetrical positions on the outer peripheral surface of the fitting convex portion 95 along the axial direction (the direction perpendicular to the paper surface of FIG. 15(b)). is provided with a recess 96 that is recessed. Since the fitting projection 95 has a concave portion 96 in which a part of the outer peripheral surface is recessed, the outer peripheral surface of the fitting projection 95 when fitting the fitting projection 95 into the hole 69 is and the inner peripheral surface of the hole 69 can be reduced. As a result, the vertical force per unit area of the hole portion 69 and the fitting projection portion 95 when fitting the fitting projection portion 95 into the hole portion 69 can be increased. As a result, the hole portion 69 or the fitting projection portion 95 can be easily deformed (elastic deformation or plastic deformation) when the fitting projection portion 95 is fitted into the hole portion 69 . It can be easily fitted into the hole 69 .

Further, a recess 95 a having a circular cross section is formed substantially in the center of the fitting projection 95 from the tip of the fitting projection 95 along the axial direction of the fitting projection 95 . By reducing the cross-sectional area of the fitting projection 95 with the concave and cutout portion 95a, the fitting projection 95 can be easily elastically deformed by the vertical force acting on the fitting projection 95 . As a result, the fitting protrusion 95 can be fitted into the hole 69 more easily, and workability when fitting the fitting protrusion 95 into the hole 69 can be improved. Further, by facilitating elastic deformation of the fitting protrusion 95 , it is possible to prevent the fitting protrusion 95 from rattling with respect to the hole 69 .

Next, with reference to FIG. 16, a second embodiment will be described. 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). explained the case. On the other hand, in the second embodiment, the opening 161 is formed through the game board 130 in the thickness direction and the outer peripheral edge of the game board 130 is partly opened. The same reference numerals are given to the same parts as in the first embodiment, and the following description is omitted. FIG. 16 is a front view of the game board 130 and the structure 170, which are the main components of the pachinko machine 1 according to the second embodiment.

As shown in FIG. 16, the game board 130 has an opening 161 formed through the thickness direction of the game board 130 (perpendicular to the paper surface of FIG. 16) and a part of the outer peripheral edge of the game board 130 opened. and a structure 170 that connects the peripheral edges of the openings 161 . In this embodiment, a part of the outer peripheral edge of the game board 130 located on the right side as viewed from the front is opened by the opening 161 . By forming the opening 161, the game board 130 has a substantially C-shaped board surface.

The structure 170 is connected between one predetermined portion 161a and another predetermined portion 161b on the periphery of the opening 161 of the game board 130. As shown in FIG. In this embodiment, the structure 170 is formed in a substantially rectangular shape when viewed from the front, and connects two openings 161 along the outer peripheral edge of the game board 130 . Note that the game board 130 and the structure 170 are made of translucent synthetic resin, like the game board 30 described in the first embodiment. Further, inside the opening 161 whose outer periphery is partly closed by the structure 170, the pattern display device 43a (see FIG. 5) is arranged as in the first embodiment.

Next, referring to FIG. 17, the connection structure between the game board 130 and the structure 170 will be described. FIG. 17 is a perspective view of the game board 130 and the structure 170. FIG. 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 includes a main body portion 172 formed in a substantially rectangular parallelepiped box shape, and a main body portion 172 extending from the front side of the main body portion 172 to both upper and lower sides (in a direction substantially parallel to the board surface of the game board 30). It mainly includes an engaging portion 171 formed in a flange shape.

A pattern display device (not shown) for variably displaying a plurality of patterns is built into the body portion 172, and a pattern display portion 173 (decorative portion) such as a liquid crystal display is arranged on the front surface of the body portion 172. . The pattern display unit 173 is not limited to a liquid crystal display, and it is possible to appropriately select a display screen such as a CRT, dot matrix, 7-segment display, or the like.

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

The game board 130 has a connecting portion (engaged portion) 131 formed at a part of the periphery of the opening 161 to receive the engaging portion 171 provided on the structure 170 . The connecting portion 131 is a portion for engaging with an 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 (horizontal direction in FIG. 17) is set to be substantially the same as the thickness of the engaging portion 171 (horizontal direction in FIG. 17).

A light scattering portion 132 is provided on the back side of the connecting portion 131 . The light scattering portion 132 is a portion for scattering light emitted from a light emitting portion 181 (described later) such as an LED arranged on the back side of the game board 130 and irradiated onto the game board 130 . The light scattering portion 132 is formed of a vertical or horizontal projection, a vertical and horizontal projection, or a wave-like projection.

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

Next, the light scattering section 132 will be described with reference to FIG. 18 . The light scattering portion 132 is formed on the back side of the connecting portion 131 as a portion such as a ridge or protrusion. A support 180 is installed on the back side of the connecting portion 131 (game board 130), and a plurality of light emitting units 181 such as LEDs are scattered in the surface direction of the support 180. FIG.

Light emitted from the light emitting portion 181 (indicated by a two-dot chain line in FIG. 18) enters and exits the light scattering portion 132 (engaged portion 131) due to the difference in refractive index between the air and the light scattering portion 132. sometimes bend. Therefore, by causing the light-emitting portion 181 to emit light, it is possible to realize an electric decoration 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 presentation effect of the pattern display portion 173 (decorative portion), the presentation effect of the light from the light emitting portion 181 can be improved.

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

In addition, when the board surface (surface) of the game board 130 is processed into ridges or protrusions to provide the light scattering section 132, the unevenness of the light scattering section 132 interferes with the movement of the game ball. When the light scattering portion 132 is provided on the rear surface (rear 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 portion 132 (unevenness). As a result, the flexibility in designing the game board 130 can be ensured.

Further, when the light scattering portion 132 is provided on the back side (rear 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 of the game board 130 is provided with an outer peripheral edge reinforcing rib 73 (see FIG. 17) that stands up toward the back side, the outer peripheral edge reinforcing rib 73 provides a back side (rear side) of the game board 130. This is because space can be secured.

In addition, by scattering light with the light scattering portion 132, the shadow of shaft-like members (not shown) such as screws screwed into the insertion holes 133 and 174 is projected from the board surface of the game board 130 and the front surface of the structure 170. You can prevent being seen. This is because the light scattering portion 132 scatters the light so that the light can flow forward of the shaft-shaped member (not shown). As a result, the light scattered by the light scattering portion 132 can make it difficult to visually recognize the joint portion (the connecting portion 131 and the engaging portion 171) between the game board 130 and the structure 170, and the gap between the game board 130 and the structure 170 can be The production effect of the seam portion can be improved.

According to the pachinko machine 1 configured as described above, the opening 161 formed through the game board 130 in the thickness direction is partly opened at the outer peripheral edge of the game board 130, and two parts of the peripheral edge of the opening 161 are opened. The locations are connected by structures 170 . Thereby, the structure 170 can be made three-dimensional using the space in the thickness direction of the game board 130 . Since the structure 170 is provided with the pattern display portion 173 (decorative portion), a three-dimensional presentation can be performed using the space in the thickness direction of the game board 130 . As a result, the amusement of the game can be greatly enhanced.

Here, in the conventional structure in which parts such as display devices and accessories are attached to the board surface of the game board, the depth direction is poor, so similar effects are likely to be adopted, and it is difficult to increase the interest of the game. In addition, in conventional game boards made of plywood (veneer), considering the machinability and mechanical strength of wooden plywood, we did not adopt a structure with an opening that opens a part of the outer periphery of the game board. hard.

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

In addition, a pattern display device 43a (see FIG. 5) having a display portion that displays a pattern in a variable manner is provided in the opening 161, and the structure 170 is arranged around the pattern display device 43a. With the pattern display portion 173 (decorative portion) of 170, not only the two-dimensional pattern effect of the pattern display device 43a but also the three-dimensional effect using the space in the thickness direction of the game board 130 can be realized. Furthermore, since the structure 170 is unitized as a game part having the pattern display portion 173 (decorative portion), the structure 170 can be easily attached to the game board 130 or replaced.

Next, with reference to FIGS. 19 and 20, a game board 130 and a structure 190 in another embodiment will be described. The same reference numerals are given to the same parts as those of the configuration described in the first embodiment and the second embodiment, and the following description will be omitted. FIG. 19 is a front view of a game board 130 and a structure 190 in another embodiment, and FIG. 20 is a schematic diagram showing the internal structure of the structure 190. As shown in FIG.

As shown in FIG. 19, the structure 190 is a member for connecting two peripheral edges of an opening 161 formed through the game board 130. It is arranged along the peripheral edge (right edge in FIG. 19). A pattern display device 43a (see FIG. 5) is arranged inside the opening 161 in which part of the outer periphery of the game board 130 is closed by the structure 190, as in the first embodiment. The structure 190 includes a body portion 171 formed in a rectangular shape when viewed from the front, and a rotating body portion 171 arranged on the front side of the body portion 171 (the front side of the paper surface of FIG. 19) and configured to be rotatable with respect to the body portion 171 . It is configured with a body 192 (movable production member).

As shown in FIG. 20, the rotating body 192 is supported by a shaft portion 193 provided at the center. The shaft portion 193 extends to the rear side (the right side in FIG. 20) of the rotating body 192 and is rotatably supported by the main body portion 191 by a supporting member (not shown). The shaft portion 193 is fitted in the gear 194 , and the rotating body 192 and the shaft portion 193 are configured to be rotatable together with the gear 194 . The gear 194 is engaged with a worm 195 , which is rotatable by a motor 196 . Therefore, when the motor 196 rotates, the worm 195 rotates, and the gear 194 engaged with the worm 195 rotates, so that the shaft portion 193 and the rotor 192 rotate.

If the rotation of the motor 196 is set to be triggered by the entry of a game ball into the through chucker (starting port) 36 or the like, various effects can be produced by the symbol display device 43a and the rotating body 192 (movable effect member). Realization is possible.

In addition to the gaming machine of the present invention, concepts of various inventions included in the above-described embodiments are shown below.

A game ball launching device for shooting game balls, a synthetic resin game board forming a game area in which the game balls launched by the game ball launching device flow down, and the game ball shooting arranged on the board surface of the game board. A game machine comprising a belt-shaped guide part for guiding game balls shot by the device to the game area along the guide surface, comprising a guide part reinforcing member fixed to the board surface of the game board, and reinforcing the guide part The member includes a fitting protrusion that fits into a recessed hole formed in the board surface of the game board, and a member that protrudes from the fitting protrusion and contacts the opposite side of the guide surface of the guide part. A game machine A1 characterized by comprising a projecting part on the opposite side of the game machine A1.

According to the game machine A1, the game area in which the game balls shot by the game ball shooting device flow down is formed by the synthetic resin game board. A strip-shaped guide portion is arranged on the board surface of the game board for guiding the game balls shot by the game ball shooting device to the game area along the guide surface. A guide portion reinforcing member is fixed to the board surface of the game board. In the guide portion reinforcing member, the fitting convex portion is fitted in a hole formed in a concave shape on the board surface of the game board, and the opposite surface side projecting portion protruding from the fitting convex portion serves as a guide for the guide portion. Contact the opposite side of the face. As a result, it is possible to suppress tilting of the strip-shaped guide portion due to the game ball traveling along the guide surface toward the game area, which pushes the guide surface toward the opposite surface side. Since tilting of the guide portion that guides the game ball to the game area can be suppressed, there is an effect that the trajectory and flight distance of the game ball guided to the game area can be stabilized.

That is, when the guide surface is pushed to the opposite side by the game ball advancing toward the game area along the guide surface and the band-shaped guide portion is tilted, the trajectory of the game ball changes and the kinetic energy of the game ball is lost. occurs. As a result, the trajectory and flying distance of the game ball guided to the game area may become unstable.

On the other hand, according to the game machine A1, by arranging the guide part reinforcing member so that the opposite surface side projection part contacts the opposite surface side of the guide surface of the guide part, the game area is moved along the guide surface. It is possible to suppress the tilting of the guide part due to the game ball advancing towards it. As a result, the trajectory and flight distance of the game ball guided to the game area can be stabilized.

A gaming machine A2 in the gaming machine A1, characterized in that the fitting projection has a recess formed in a recessed shape on a part of the outer peripheral surface.

According to the gaming machine A2, since the concave portion is formed in a concave shape in a part of the outer peripheral surface of the fitting convex portion, the outer peripheral surface of the fitting convex portion and the fitting convex portion when fitting the fitting convex portion into the hole The contact area with the inner peripheral surface of the hole can be reduced. As a result, the vertical effectiveness per unit area of the hole and the fitting protrusion when fitting the fitting protrusion into the hole can be increased. As a result, the hole or the fitting projection can be easily deformed (elastic deformation or plastic deformation) when fitting the fitting projection into the hole. There is an effect that it is possible to easily fit the mating portion into the hole.

A gaming machine A3 in the gaming machine A1 or A2, characterized in that the concave portion is formed in a slot shape from the distal end of the fitting convex portion toward the base end.

According to the game machine A3, since the concave portion is formed in a slot shape from the tip of the fitting convex portion toward the base end, the elastic deformation of the fitting convex portion due to the slot is used to fit into the hole. The mating protrusions can be fitted. As a result, in addition to the effects of the game machine A1 or A2, it is possible to easily fit the fitting convex portion into the hole, and by utilizing the elastic deformation of the fitting convex portion, the hole and the fitting convex portion can be easily aligned. Since it is possible to prevent the occurrence of a gap, there is an effect that the fitting protrusion fitted in the hole is less likely to rattle.

In the gaming machine A3, the guiding portion reinforcing member is arranged such that the direction of the slot of the concave portion viewed from the axial direction of the fitting convex portion is non-parallel to the longitudinal direction of the guiding portion. Game machine A4.

According to the game machine A4, since the guide portion reinforcing member is arranged so that the direction of the slot of the concave portion viewed from the axial direction of the fitting convex portion is non-parallel to the longitudinal direction of the guide portion, the guiding portion of the strip-shaped guide portion When the guide surface is pushed to the opposite surface side by a game ball traveling along the surface toward the game area, the fitting projection can be made difficult to be elastically deformed. As a result, tilting of the guide portion can be suppressed. As a result, in addition to the effects of the game machine A3, there is an effect that the trajectory and flying distance of the game ball guided to the game area can be further stabilized.

That is, the fitting convex portion is difficult to be elastically deformed by a load parallel to the direction of the slot, and is likely to be elastically deformed by a load perpendicular to the direction of the slot. Therefore, by arranging the guide portion reinforcing member so that the direction of the slot of the fitting projection is parallel to the longitudinal direction of the guide portion, when the guide surface of the guide portion is pushed to the opposite side, the fitting projection The guide portion is likely to tilt due to elastic deformation of the portion. On the other hand, if the guide portion reinforcing member is arranged so that the direction of the slot of the fitting convex portion is not parallel to the longitudinal direction of the guide portion, when the guide surface of the guide portion is pushed to the opposite side, Elastic deformation of the fitting projection can be made difficult. This makes it difficult for the guide portion to tilt toward the side opposite to the guide surface.

In any one of the game machines A1 to A4, the guide portion reinforcing member is arranged on the guide surface side of the guide portion so as to face the opposite surface side projecting portion, and is located on the guide surface side in contact with the guide surface. A gaming machine A5 comprising a protruding portion, wherein the height of the protruding portion on the guide surface side is set lower than the height of the protruding portion on the opposite surface side.

According to the game machine A5, since the guide surface side projecting portion arranged on the guide surface side of the guide portion facing the opposite surface side projecting portion contacts the guide surface of the guide portion, the opposite surface side projecting portion The guide portion is held between the portion and the guide surface side projecting portion. Since the guide portion is held by the guide portion reinforcing member from both the guide surface and the opposite surface, it is possible to reliably prevent the guide portion from tilting in addition to the effect of any one of the game machines A1 to A4. As a result, there is an effect that the trajectory and flying distance of the game ball guided to the game area can be further stabilized.

In addition, since the height of the guide surface side projecting portion disposed on the guide surface side of the guide portion is set lower than the height of the opposite surface side projecting portion, the progress of the game ball along the guide surface is prevented by the guide surface side projecting portion. It is possible to prevent the setting part from interfering. If the game ball interferes with the projecting part on the guide surface side, the kinetic energy of the game ball is lost and the flight distance of the game ball guided to the game area becomes unstable. It is possible to prevent the flying distance of the game ball hit from becoming unstable.

In any one of the gaming machines A1 to A5, the opposite surface side projecting portion includes an inclined portion inclined downward from the top portion toward the fitting convex portion side, and a guide portion connected to the inclined portion and connected to the inclined portion. A gaming machine A6 comprising a contact portion facing the opposite surface and contacting at least a part of the opposite surface.

According to the gaming machine A6, when the guiding portion reinforcing member and the guiding portion are arranged on the board surface of the game board, first, the fitting convex portion of the guiding portion reinforcing member is inserted into the hole of the game board. Next, the guide portion is arranged along the inclined portion of the projecting portion on the opposite surface side so that the opposite surface faces the contact portion of the guide portion reinforcing member. Since the slanted portion is slanted downward from the apex toward the fitting convex portion side, and the contact portion is connected to the slanted portion, the guide portion can be smoothly arranged on the contact portion along the slanted portion. can. As a result, in addition to the effect of any one of the game boards A1 to A5, the guide part can be smoothly arranged on the board surface of the game board, and the effect of improving the workability of the arrangement work of arranging the guide part on the board surface. be.

According to the game machine A7, since nails are planted in the board surface of the thick part located on the back side of the game area of the game board, nail holding power can be ensured by ensuring the driving depth of the nails. In addition, since the thin portion, which is set smaller in thickness than the thick portion, is connected to the thick portion, the game board does not have the thin portion (the game board is uniformly formed with the thickness of the thick portion). Compared to , the game board can be made lighter. Furthermore, since the outer peripheral edge reinforcing ribs are erected from the outer peripheral edge of the thin portion to the back side, the rigidity of the thin portion can be ensured. As a result, it is possible to reduce the weight of the game board while ensuring its rigidity, and to increase the holding power of the nails planted on the board surface.

In addition, since the projecting portion is continuously formed by protruding from a predetermined portion of the thin portion toward the back side, and the hole portion is formed through the thin portion and the projecting portion, the fitting convex portion to be fitted into the hole portion can be fitted. Depth can be secured. As the fitting depth of the fitting projection fitted into the hole increases, there is a tendency that the fitting projection fitted into the hole is less likely to swing in the direction perpendicular to the axial direction. By securing the fitting depth of the fitting protrusion fitted in the hole, the guide part reinforcing member fixed to the game board can be made difficult to swing. By making it difficult to swing the guide portion reinforcing member fixed to the game board, it is possible to suppress the tilting of the guide portion that guides the game ball to the game area. can be further stabilized.

Further, since the projecting portion is continuously formed by protruding from a predetermined portion of the thin portion toward the back side, and the hole portion is formed through the projecting portion and the thin portion, the area of the thick portion must be increased to form the hole portion. can be made unnecessary. Although the mass of the game board increases by the amount of the projecting portion (excluding the hole) connected to the thin portion, it is not necessary to increase the area of the thick portion, so the increase in the mass of the game board can be suppressed. . Furthermore, since the protruding portion through which the hole is formed functions as a rib that enhances the rigidity of the thin portion around the hole, the rigidity of the thin portion around the hole can be ensured.

As described above, according to the game machine A7, in addition to the effects of any one of the game machines A1 to A6, it is possible to reduce the weight of the game board while ensuring the rigidity of the game board, and to hold the nails planted on the board surface. In addition to increasing the force, there is an effect that the trajectory and flying distance of the game ball guided to the game area can be further stabilized.

In this type of game machine, the conventional game board is generally made of a wooden plywood (veneer) with a synthetic resin film printed with a pattern attached to the surface. In recent years, synthetic resin game boards have been adopted from the viewpoint of design and recyclability (for example, Patent Document 1: JP-A-10-113428 (especially FIG. 5)). In the technique disclosed in Patent Document 1, a game ball is shot by operating a handle, and the game ball is guided to a game area by a game ball rail arranged on the board surface of the game board.
However, in the gaming machine as described above, when a game ball is launched, after the game ball collides with the game ball rail (guide portion), it advances along the game ball rail, and the energy of the game ball causes the game ball rail to travel. tilts so that it spreads outward. When the game ball rail (guide portion) tilts, the trajectory of the game ball changes or the kinetic energy of the game ball is lost. As a result, there may arise a problem that the trajectory and flight distance of the game ball guided to the game area become unstable.
This technical idea was made to solve the above-mentioned problems, etc., and aims to provide a game machine that can stabilize the trajectory and flying distance of a game ball guided to a game area. and
