The second control board unit 46 is a unit including a payout control device (payout control board), a launch control device (fire launch control board), and a power supply device (power supply board).

  Next, the game board 30 on which various game parts and the like are arranged will be described with reference to FIG. FIG. 5 is a front view of the game board 30 on which game parts and the like are arranged. The game board 30 is a light-transmitting synthetic resin member integrally formed by injection molding, and has a plurality of large and small openings penetrating in the front-rear direction at the time of injection molding. Each opening is provided with a through gate 34, a variable winning device 35, a through chucker (starting port) 36, a winning port 37, a general winning port 38, a variable display unit 43, a center frame 47, and the like. These are mounted on the surface of the game board 30 by screwing a screw or the like into a prepared hole (screw insertion hole) formed by a drill or the like.

  In the present embodiment, the variable display unit 43 is arranged substantially at the center of the game board 30, a through-chucker (starting opening) 36 is arranged below the variable display unit 43, and a winning opening 37 is arranged further below. Further, a through gate 34 is disposed on the right side of the variable display unit 43, and a plurality of general winning openings 38 are disposed on both lower sides of the game board 30, respectively. The winning opening 37 is additionally provided with an electric accessory that is activated (opened) under predetermined conditions.

  When a game ball enters the variable winning device 35, the winning opening 37, and the general winning opening 38, it is detected by a detection switch (not shown), and based on the detection result, the upper plate 6 (or the lower plate 8 in some cases). A predetermined number of prize balls are paid out. In addition, an out port 39 is provided at a lower portion of the game board 30, and game balls that have not entered various winning ports or the like are guided to a ball discharge path (not shown) through the out port 39. The out port 39 is formed so as to penetrate in the thickness direction when the game board 30 is formed by the design of a forming die.

  In addition, the variable display unit 43 is provided with a symbol display device 43a that displays symbols variably with a winning in the starting port 36 as a trigger. The symbol display device 43a is configured as a liquid crystal display device having a relatively large 8-inch liquid crystal display, and the display content is controlled by a display control device. On the symbol display device 43a, symbols are displayed side by side, for example, on the left, center and right, and these symbols are variably displayed as scrolled up and down. The symbol display device 43a may be a display device having a liquid crystal display of 10 inches or 7 inches other than 8 inches, a display device of a wide size, or a CRT, dot matrix, 7 segment, or other type of display screen. May be configured. A center frame 47 is provided so as to surround the symbol display device 43a.

  The center frame 47 has a frame shape penetrating in the front-rear direction, and various decorations are provided on a front surface. The center frame 47 surrounds the symbol display device 43a to prevent the game balls from entering the opening 61 in which the variable display unit 43 is mounted, and to allow the game balls to enter the center frame 47 from the board of the game board 30. To the board again.

  In addition, a large number of nails are planted on the game board 30 in order to appropriately disperse and adjust the falling direction of the game ball, and various members (accessories) such as a windmill (not shown) are provided. ing. A nail or a windmill is attached to the game board 30 by drilling a prepared hole (a nail insertion hole) in the game board 30 with a drill or the like and driving the hole into the prepared hole. This is to prevent the gaming board 30 from being cracked by driving nails or windmills.

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

  On the surface of the game board 30, a film made of a synthetic resin having a light-transmitting property is attached. The film has a plurality of printed portions colored by printing. The plurality of printing portions are provided with a difference in light transmission, and opaque portions having no light transmission are also provided. Thus, when light is irradiated from the back side of the game board 30 toward the game board 30, light and darkness is generated in the printing section due to a difference in translucency of the printing section, so that the rendering effect can be enhanced.

  Next, the game board 30 will be described with reference to FIGS. FIG. 6 is a front view of the game board 30, and FIG. 7 is a rear view of the game board 30. 6 and 7 show a state before a pilot hole (a screw insertion hole) into which a screw or the like is inserted and a pilot hole (a nail insertion hole) into which a nail or a windmill is driven are drilled in the game board 30. 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 port) 36 is attached, the opening 66 is a through hole to which a winning opening 37 is attached, and the opening 67 is a general winning opening 38 to be attached. Through hole.

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

  As shown in FIG. 7, the game board 30 is located at a substantially central portion on the back surface of the game board 30 and has a thick portion 70 whose outer shape in a rear view is formed in a substantially circular shape, and is formed around the thick portion 70. A slanted surface portion 71 having a substantially circular outer shape in a rear view, a thin portion 72 formed around the slanted surface portion 71 and having a substantially rectangular outer shape in a rear view, and a periphery of the thinned portion 72 And a peripheral edge reinforcing rib 73 erected at the bottom.

  Next, a cross-sectional shape of the game board 30 will be described with reference to FIG. FIG. 8 is a sectional end view of the game board 30 taken along the line VIII-VIII in FIG. As shown in FIG. 8, the game board 30 is formed with a flat surface on the board side (the front side, the lower side in FIG. 8), and the thick portion 70 is formed on the back side (the upper side in FIG. 8), and the thickness is reduced. It is set almost constant. The inclined surface portion 71 is formed continuously with the thick portion 70 and is formed so that the plate thickness becomes gradually smaller as approaching the periphery of the game board 30 (toward the outer periphery). The thin portion 72 is provided continuously around the inclined surface portion 71 and has a thickness smaller than the thickness 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 provided continuously around the thin portion 72, and projects rearward from the outer peripheral edge of the thin portion 72. In addition, since the height (vertical direction in FIG. 8) of the outer peripheral edge reinforcing rib 73 is set to a value larger than the thickness of the thick portion 70, the game board 30 needs to be externally attached to the resin base 20 of the main body frame 3. When the rear end portion of the peripheral edge reinforcing rib 73 is brought into contact with the front surface of the resin base 20, the thick portion 70 can be prevented from interfering with the resin base 20.

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

  Further, in the game board 30, since the thickness of the thick portion 70 is set to be smaller than the height of the outer peripheral edge reinforcing ribs 73, the game board 30 has a uniform thickness in which the height of the outer peripheral edge reinforcing ribs 73 is the thickness. It can be lighter than a board. A space can be provided on the back side of the thick portion 70 by the thickness of the thick portion 70 set to be smaller than the height of the outer peripheral edge reinforcing ribs 73, so that decorations and the like are arranged in the space on the back side. It is possible to do. Since a light-emitting element such as an LED can be arranged in the space on the back side, the effect can be improved.

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

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

  An inclined surface portion 71 is formed on the outer periphery of the thick portion 70. The inclined surface portion 71 is set so that the thickness is gradually reduced from the thick portion 70 toward the outside, and is connected to the thin portion 72. Thereby, at the time of forming the game board 30, it is possible to suppress the occurrence of deformation due to the difference in thickness between the thick portion 70 and the thin portion 72. That is, the game board 30 is molded by melting and filling a cavity of a molding die with a synthetic resin, and after curing, a molded body is taken out from the molding die. Since the cooling rate of the compact is higher in the thinner portion 72 having a smaller thickness than in the thicker portion 70 having a larger thickness, residual stress is generated due to the difference in cooling rate, and the game board 30 is liable to be deformed such as warpage. However, the generation of the residual stress due to the difference in the cooling rate can be buffered by the inclined surface portion 71 coupled between the thin portion 72 and the thick portion 70. As a result, deformation such as warpage of the game board 30 can be suppressed.

  The hole 68 formed at the boundary between the thick portion 70 and the inclined surface 71 is a portion into which a fitting pin (described later) spot-welded to the inner rail 32 is fitted. The hole 68 formed on the outer peripheral side of the game board 30 from the boundary between the thick part 70 and the inclined surface part 71 and formed in the thin part 72 and the peripheral part reinforcing rib 73 is spot-welded to the outer rail part 31. This is a portion where a mating pin (described later) is inserted. The hole 68 is provided with a cylindrical protrusion 68a standing upright 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 68 a is formed around the hole 68, the plate thickness around the hole 68 can be increased. As a result, the load per unit area applied by the fitting pin to the inner periphery of the hole 68 can be reduced, so that cracks around the hole 68 (particularly, the thin portion 72) can be hardly generated. Further, since the depth of the hole 68 (the front-rear direction of the game board 30) can be increased by the protruding portion 68a, the holding force of the fitting pin can be increased. 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 projection 68a (hole 68) into which a fitting pin spot-welded to the inner rail portion 32 is inserted is formed at a boundary between the thick portion 70 and the inclined surface portion 71, and a thick portion is formed on the outer periphery of the projection 68a. The portion 70 and the inclined surface portion 71 are provided continuously. Since the thickness of the thick portion 70 and the inclined surface 71 is greater than the thickness of the thin portion 72, the projecting length of the projecting portion 68 a with respect to the thick portion 70 and the inclined surface 71 is larger than the projecting length of the projecting portion 68 a with respect to the thin portion 72. Can be smaller. As a result, the bending moment of the protruding portion 68a with respect to the thick portion 70 and the inclined surface portion 71 can be made smaller than the bending moment of the protruding portion 68a with respect to the thin portion 72. The bending strength of the projection 68 a protruding from the thin portion 72 can be improved.

  In addition, a fitting pin spot-welded to the inner rail 32 is inserted into a hole 68 formed in a protrusion 68a formed at a boundary between the thick part 70 and the inclined surface part 71. By providing the thick portion 70 inside the inner rail portion 32 where the game area PE is formed, it is possible to secure a holding force for nails, windmills, and the like. By providing a projection 68a (hole 68) into which a fitting pin spot-welded to the inner rail portion 32 is inserted at a boundary between the thick portion 70 and the inclined surface portion 71, the area of the thick portion 70 becomes excessive. Can be prevented from increasing. By preventing the thick portion 70 from expanding outside the region (in the inner rail portion 32) where the game region 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. Unnecessarily large size can be prevented.

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

  The hole 69 is a portion into which a fitting convex portion (described later) of the guide portion reinforcing member 50 is fitted, and is formed through the thin portion 72. Since the protrusion 69 a is formed around the hole 69, the plate thickness around the hole 69 can be increased. As a result, the load per unit area applied by the fitting projection to the inner periphery of the hole 69 can be reduced, so that cracks around the hole 69 (thin portion 72) can be less likely to occur. In addition, since the depth of the hole 69 (the front-rear direction of the game board 30) can be increased by the protrusion 69a, the holding force of the fitting projection can be increased. Thereby, 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 provided with recessed portions 73a, 73b, 73c in which a part of the end face on the back side (front side in FIG. 7) is recessed in the height direction (the height of the rib is reduced). . The concave portions 73a and 73c are formed at positions facing the outer peripheral edge reinforcing ribs 73 (left and right ribs), and the concave portions 73b intersect with the outer peripheral edge reinforcing ribs 73 (left and right ribs) where the concave portions 73a and 73c are formed. It is formed on the outer peripheral edge reinforcing rib 73 (lower rib). Since the recessed portions 73a and 73c are formed at positions opposed to the outer peripheral edge reinforcing ribs 73, the molded game board 30 is placed on a base having a flat surface formed on the upper surface with the outer peripheral edge reinforcing ribs 73 downward. In the case where the game board 30 is placed with its back side facing down, there is a gap between the flat surface and the game board 30 (the outer peripheral edge reinforcing rib 73) by the amount of the recesses 73a and 73c. A fingertip or the like of a hand can be inserted into the gap, and the gaming board 30 placed on a flat surface can be lifted using the inserted fingertip or the like as a clue.

  On the other hand, when the concave portions 73a, 73b, and 73c are not formed on the rear end surface of the outer peripheral edge reinforcing rib 73, the outer peripheral edge reinforcing rib 73 is placed on a base having a flat surface formed on the upper surface. When the game board 30 is placed with the rear side facing downward, the entire periphery of the rear side end face of the outer peripheral edge reinforcing rib 73 comes into close contact with a flat surface (a gap cannot be formed). In such a case, it is difficult to insert a fingertip or the like between the outer peripheral edge reinforcing rib 73 and the flat surface (table), so that there is 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 recesses 73a, 73b, 73c in the outer peripheral edge reinforcing rib 73.

  The openings 62 are through holes to which the protruding pins 60 are attached, and are formed at two diagonal positions of the game board 30. A reinforcing rib 62a is provided upright 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 and 62a and the protrusions 68a and 69a are set to be substantially the same as the height of the peripheral edge reinforcing rib 73. Thereby, in a state where the game board 30 is placed on the base having a flat surface formed on the upper surface with the outer peripheral edge reinforcing ribs 73 facing down (back side facing down), 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 and 62a, the protrusions 68a and 69a, and the peripheral edge reinforcing rib 73.

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

  In particular, the protrusions 68a for fixing the outer rail portion 31 and the inner rail portion 32 are located on a substantially semi-annular line and are widely scattered on the game board 30. Even when a concentrated load is applied to the game board 30, large bending deformation can be prevented from being generated on the board surface of the game board 30. This prevents the game board 30 from being damaged by the load applied to the game board 30 when a nail is planted in the game board 30 or various game parts are attached.

  Next, the opening 62 and the protruding pin 60 will be described with reference to FIG. FIG. 9 is a sectional end view of the gaming board 30 along the line IX-IX in FIG. As shown in FIG. 9, the protruding pin 60 is a substantially columnar member formed of a member separate from the game board 30, and has a flange portion 60 a projecting radially from the outer peripheral surface (the horizontal direction in FIG. 9). A fitting insertion portion 60b extending from the flange portion 60a to the other axial side is continuously provided. The insertion portion 60b is a portion that is inserted into the opening 62, and the flange portion 60a is a portion that regulates the insertion depth of the insertion portion 60b that is inserted into the opening 62. On the other hand, a recess 62b for receiving the flange 60a is formed on the board surface of the game board 30. The concave portion 62b is continuously provided around the opening 62 at substantially the same depth as the thickness of the flange portion 60a. 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).

  The end face of the reinforcing rib 62a on the back side (lower side in FIG. 9) is set at substantially the same height position as the end face on the back side (lower side in FIG. 9) of the peripheral edge reinforcing rib 73. Thus, the depth of the opening 62 (vertical direction in FIG. 9) can be increased, so that the insertion depth at which the insertion portion 60b is inserted into the opening 62 can be increased. On the other hand, when the reinforcing ribs 62 a are not formed, the depth of the opening 62 is the same as the thickness of the thin portion 72. In this case, the holding force for holding the fitting portion 60b in the opening 62 is smaller than in the present embodiment, and the protruding pin 60 is likely to rattle or come off. By providing the reinforcing rib 62a as in the present embodiment, it is possible to prevent that.

  Further, since the game board 30 in which the fitting portion 60b is inserted into the opening 62 has the flange 60a, the projecting pin 60 projects from the board surface of the game board 30 by a predetermined length. On the other hand, the reinforcing rib 62a is set such that a recess (hole) deeper than the protruding length of the protruding pin 60 from the board surface is formed on the back side (the lower side in FIG. 9). Since the diameter of the protruding pin 60 is formed to be 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, the diameter of one game board 30 increases. The protruding protruding pins 60 are inserted into the recesses (holes) in the reinforcing ribs 62a from the back side of another game board 30. As a result, it is possible to prevent the game boards 30 stacked in a flat state from being displaced in the board surface direction.

  By forming the protruding pin 60 as a separate member from the game board 30 as in the present embodiment, the game board is formed until the protruding pin 60 is fitted into the opening 62 after the game board 30 is formed. The projecting pin 60 can be prevented from projecting from the board surface of the panel 30. This prevents the protruding pins 60 from hindering the transport of the game board 30 and from damaging the protruding pins 60 until the protruding pins 60 are fitted into the openings 62 after the game board 30 is formed. it can. Further, after the projecting pin 60 is fitted into the opening 62, if the projecting pin 60 becomes unnecessary when assembling the pachinko machine 1 or the like, the projecting pin 60 can be removed from the opening 62. This makes it possible to smoothly assemble the pachinko machine 1 and the like.

  Further, when the game board 30 is formed, the protruding pins can be formed integrally with the game board. When fitting (inserting) the protruding pin 60 to the game board 30 as in the present embodiment, it is necessary to prepare the protruding pin 60 as a separate member and insert the protruding pin 60 into the game board 30. On the other hand, by forming the projecting pin integrally with the game board, it is not necessary to prepare the projecting pin 60 as a separate member, so that the number of components can be reduced. Further, the operation of inserting the protruding pin 60 into the game board 30 can be omitted.

  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 synthetic resin into a molding die, and an outer peripheral edge reinforcing rib 73 is erected on the rear side of a flat board surface (front surface). When the game boards 30 made of synthetic resin are stacked and conveyed, there is a problem in that the position is shifted and the slide-down easily occurs as compared with the case where game boards made of wooden plywood are stacked and conveyed. This is because the game board 30 made of synthetic resin has higher surface smoothness and a smaller friction coefficient than the game board made of wooden plywood, so that it is easier to slide.

  On the other hand, according to the present embodiment, the game boards 30 are stacked by inserting the protruding pins 60 of one game board 30 into the recesses (holes) in the reinforcing ribs 62a of the other game boards 30. It can be easily transported. In addition, the fingertips of the hand can be easily inserted into the gap formed by the concave portion 73a formed on the end surface of the outer peripheral edge reinforcing rib 73, so that the gaming board 30 can be easily lifted. In addition, since the depressions 73a and 73c are formed at positions facing the outer peripheral edge reinforcing ribs 73, the fingertips of the hands and the like can be lifted in a well-balanced manner by inserting the fingertips of the hands into the depressions 73a and 73c from the left and right. Further, the concave portion 73b is formed on the outer peripheral edge reinforcing rib 73 (located on the lower side in FIG. 7) intersecting with the outer peripheral edge reinforcing rib 73 (located on the left and right in FIG. 7) in which the concave portions 73a and 73c are formed. The game board 30 can be supported from three sides of the game board 30, and the game board 30 can be transported in a well-balanced manner.

  Next, the guide portion reinforcing member 50 will be described with reference to FIGS. 11 is a partially enlarged front view of the game board 30 to which the guide portion (outer rail portion 31) and the guide portion reinforcing member 50 are fixed, FIG. 12 is a partially enlarged rear view thereof, and FIG. 13 is a guide portion reinforcing member 50. It is a perspective view of. The guide portion reinforcing member 50 is a member for preventing the outer rail portion 31 that the game ball fired from the game ball firing device 21 first collides with from swinging. Since the guide portion reinforcing member 50 is addressed to the outer rail portion 31, swing of the outer rail portion 31 is prevented. As a result, the trajectory of the game ball and the flight distance of the game ball to the game area PE can be stabilized.

  First, the outer rail portion 31 will be described with reference to FIG. The outer rail portion 31 is formed of a metal (stainless steel) band-shaped 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 31 is erected on the game board 30 by fitting the fitting pin 31 a into a hole 68 formed in the game board 30.

  Further, the outer rail portion 31 includes a bent portion 31b whose end in the longitudinal direction is bent and bent in a substantially U-shape. The bent portion 31b is a portion for preventing the edge of the outer rail portion 31 in the longitudinal direction from swinging, and guides the outer rail portion 31 through which a game ball fired from the game ball firing device 21 is guided. It is bent to the opposite side (back side) of the surface 31c. Thereby, when a game ball fired from the game ball launching device 21 collides with the guide surface 31c of the outer rail portion 31, the edge of the outer rail portion 31 tilts toward the opposite surface side (back surface 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. That is, the guide portion reinforcing member 50 is disposed between the fitting pins 31a. Since the fitting pins 31a are fixed to the outer rail 31 at appropriate intervals, the outer rail 31 easily swings between the fitting pins 31a. However, by arranging the guide portion reinforcing member 50 between the fitting pins 31a, it is possible to 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 (when viewed from the board side of the game board 30), and is opposite to the guide surface 31 c of the outer rail portion 31. The base portion 51 located on the surface side, the opposite-side projecting portion 52 erected on the base portion 51, and the base portion 51 in a direction opposite to the direction in which the opposite-side projecting portion 52 is erected. It mainly comprises a protruding fitting projection 55.

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

  The opposite surface side protruding portion 52 has an inclined portion 52a which is inclined downward from the top toward the base portion 51 side (board surface side), and is provided at least one at a position facing the outer rail portion 31 and connected to the inclined portion 52a. And a contact portion 52b with which the portion contacts. A fitting projection 55 is protruded from one side edge of the base portion 51 and the opposite surface side protruding portion 52. A rod-shaped columnar portion 53 is provided upright along the opposite surface side protruding portion 52 on the other side edge facing one side edge of the base portion 51 and the opposite surface side protruding portion 52. The columnar portion 53 is a portion for improving the bending rigidity of the opposite surface side protruding portion 52, is formed integrally with the base portion 51 and the opposite surface side protruding portion 52, and is located on the back side of the contact portion 52b. Accordingly, the protruding portion 52 on the side opposite to the axial direction of the columnar portion 53 can be hardly bent and deformed as compared with the case where the columnar portion 53 is not formed.

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

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

  The length of one side edge of the base portion 51 at which the fitting projection 55 protrudes is set shorter than the length of the other side edge facing the one side edge. Since the other side edge of the base portion 51 is continuously provided on the bottom side of the columnar portion 53 and the reinforcing portion 54, the bottom area of the base portion 51 gradually increases from one side edge of the base portion 51 to the other side edge. It is set to be. By making the bottom area of the base part 51 located far from the fitting projection 55 larger than the bottom area of the base part 51 located near the fitting projection 55, the bottom part located far from the fitting projection 55 is formed. Area shortage can be prevented. As a result, the swing of the opposite-side projecting portion 52 at a position far from the fitting projection 55 can be suppressed.

  Since the guide portion reinforcing member 50 includes the base portion 51 disposed along the outer rail portion 31, as shown in FIG. Can be shifted to the end (bent portion 31b) side of the outer rail portion 31. As a result, the position of the fitting pin 31a for fixing the outer rail portion 31 to the game board 30 can be made closer to the position of the opposite surface side protruding portion 52 (contact portion 52b). By bringing the contact portion 52b closer to the fitting pin 31a for fixing the outer rail portion 31, the outer rail portion 31 can be hardly bent between the fitting pin 31a and the contact portion 52b. As a result, the outer rail portion 31 can be effectively reinforced by the guide portion reinforcing member 50.

  The fitting projection 55 is a portion that is fitted into a hole 69 formed in the game board 30 in order to fix the guide portion reinforcing member 50 to the game board 30. In the present embodiment, the fitting projection 55 is substantially circular. It is formed in a column 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 set so that the area of the cross section orthogonal to the axis gradually decreases toward the distal end side. Since the reduced diameter portion 55a is formed, the fitting projection 55 can be easily inserted into the hole 69. Further, since the fitting projection 55 and the hole 69 are formed in a substantially circular cross section, it is possible to omit a fine position adjustment when the guide portion reinforcing member 50 is inserted into the hole 69. As a result, the workability of inserting the guide portion reinforcing member 50 into the hole 69 can be improved.

  With reference to FIG. 12, the fitting projection 55 will be described. FIG. 12 is a partially enlarged rear view of the game board 30 provided with the guide portion (outer rail portion 31) and the guide portion reinforcing member 50. In FIG. 12, the position of the outer rail portion 31 arranged on the board surface of the game board 30 is shown by an imaginary line (two-dot chain line).

  As shown in FIG. 12, the fitting projection 55 includes a concave portion 56 in which a part of the outer peripheral surface is formed in a concave shape. Since the concave portion 56 forms a part of the outer peripheral surface of the fitting convex portion 55 in a concave shape, when the fitting convex portion 55 is fitted into the hole portion 69, the outer peripheral surface of the fitting convex portion 55 and the hole portion 69 are formed. Can be reduced in contact area with the inner peripheral surface. As a result, the vertical effectiveness per unit area of the hole 69 and the fitting protrusion 55 when the fitting protrusion 55 is fitted into the hole 69 can be increased. Thereby, when the fitting protrusion 55 is fitted into the hole 69, the hole 69 or the fitting protrusion 55 can be easily deformed (elastic deformation or plastic deformation). 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 base end. As a result, the fitting protrusion 55 can be fitted into the hole 69 by utilizing the elastic deformation of the fitting protrusion 55 due to the sliding. Thereby, the fitting projection 55 can be easily fitted into the hole 69. Further, by utilizing the elastic deformation of the fitting projection 55, it is possible to prevent a gap from being formed between the hole 69 and the fitting projection 55. As a result, the fitting projection 55 fitted into the hole 69 can be made less likely to rattle.

  Further, in the present embodiment, the sliding direction of the concave portion 56 as viewed from the axial direction of the fitting convex portion 55 (the direction perpendicular to the plane of FIG. 12) is non-parallel to the longitudinal direction of the outer rail portion 31. Thereby, when the guide surface 31c is pushed to the opposite surface side (the lower side in FIG. 12) by the game ball proceeding toward the game area PE along the guide surface 31c of the belt-shaped outer rail portion 31, the fitting projection is formed. The portion 55 can be hardly elastically deformed. Thereby, the guide portion reinforcing member 50 can be hardly tilted.

  That is, the fitting projection 55 is hardly elastically deformed by a load parallel to the sliding direction, and is easily elastically deformed by a load perpendicular to the sliding direction. This is because when a load parallel to the sliding direction is applied to the fitting protrusion 55, the fitting protrusion 55 is deformed so as to reduce the gap between the slit-shaped recesses 56. Therefore, if the guide portion reinforcing member 50 is arranged so that the sliding direction of the fitting convex portion 55 is parallel to the longitudinal direction of the outer rail portion 31, the guide surface 31c of the outer rail portion 31 is pushed to the opposite surface side. When this is done, the outer rail portion 31 tends to tilt due to the elastic deformation of the fitting projection 55. On the other hand, if the guide portion reinforcing member 50 is arranged so that the sliding direction of the fitting convex portion 55 is not parallel to the longitudinal direction of the outer rail portion 31, the guide surface 31c of the outer rail portion 31 becomes the opposite surface. When pushed to the side, the fitting projection 55 can be made less likely to be elastically deformed. Thereby, the guide portion reinforcing member 50 can be hardly tilted.

  In particular, by making the longitudinal direction of the outer rail portion 31 perpendicular to the sliding direction of the concave portion 56, the fitting convex portion 55 can be made most difficult to be elastically deformed by a load parallel to the sliding direction. Accordingly, it is possible to suppress the guide portion reinforcing member 50 from tilting together with the tilting of the outer rail portion 31. As a result, it is possible to suppress the outer rail portion 31 from tilting with the progress of the game ball, and to stabilize the trajectory and flight distance of the game ball traveling along the outer rail portion 31.

  Note that by making the longitudinal direction of the outer rail portion 31 and the sliding direction of the concave portion 56 non-perpendicular, it is possible to use the elastic deformation of the fitting convex portion 55 by a load parallel to the sliding direction. is there. In particular, by making the longitudinal direction of the outer rail portion 31 parallel to the sliding direction of the concave portion 56, the elastic deformation of the fitting convex portion 55 can be used most actively. As the outer rail portion 31 tilts due to the progress of the game ball, the guide portion reinforcing member 50 (the opposite protruding portion 52) is tilted together to elastically deform the fitting convex portion 55, and the fitting convex portion 55 By the restoring force, it is possible to restore the guide portion reinforcing member 50 (the opposite protruding portion 52) and the outer rail portion 31 to their original positions. By utilizing the elastic deformation of the fitting projection 55, it is possible to prevent the guide portion reinforcing member 50 from being damaged by a load (a load by a game ball) 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 to stabilize the trajectory and flight distance of the game ball traveling along the outer rail portion 31.

  In addition, the fitting protrusion 55 has a concave notch 56a having a substantially circular cross-section and connected to the recess 56 along the axis (perpendicular to FIG. 12) substantially at the center of the fitting protrusion 55. ing. Since the concave notch 56a is formed, the cross-sectional area of substantially the center (near the axis) of the fitting projection 55 can be reduced. Thereby, the cross-sectional shape of the fitting protrusion 55 on both sides of the recess 56 in the axial direction can be made substantially fan-shaped. As a result, when a load parallel to the sliding direction is applied to the fitting protrusion 55, the fitting protrusion 55 can be deformed so as to reduce the cross-sectional area of the recess 56a. Thus, the fitting protrusion 55 can be fitted into the hole 69 by utilizing the elastic deformation of the fitting protrusion 55 caused by the concave notch 56a. Thereby, the fitting projection 55 can be easily fitted into the hole 69.

  Since the amount of elastic deformation of the fitting protrusion 55 due to the recess 56a is smaller than the amount of elastic deformation of the fitting protrusion 55 due to the recess 56, the fitting protrusion in the sliding direction (substantially the vertical direction in FIG. 12). The amount of elastic deformation of the fitting projection 55 in the direction orthogonal to the sliding (the substantially right-left direction in FIG. 12) can be made different from the amount of elastic deformation of the fitting 55. Specifically, the amount of elastic deformation of the fitting protrusion 55 in the sliding direction (substantially up and down direction in FIG. 12) is determined by changing the amount of elastic deformation of the fitting protrusion 55 in a direction perpendicular to the sliding (substantially left and right direction in FIG. 12). Can be smaller than quantity. Therefore, it is possible to prevent the effect that the guide portion reinforcing member 50 is hardly tilted from being impaired when the concave portion 56a is formed.

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

  Returning to FIG. 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 protrusion portion 52, and is provided on the guide surface side protrusion contacting the guide surface 31c. A portion 57 is provided. As shown in FIGS. 11 and 13, the guide surface side protruding portion 57 is protruded from a part of the fitting convex portion 55 in the axial direction on the base end side (the near side in FIG. 11). A groove 58 into which the outer rail 31 is inserted is formed between the guide surface side projecting portion 57 and the opposite surface side projecting portion 52.

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

  Since the guide portion reinforcing member 50 includes the guide surface side projecting portion 57, the outer rail portion 31 is held in the groove 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 protruding portion 52 and the guide surface side protruding portion 57 of the guide portion reinforcing member 50, the tilting of the outer rail portion 31 can be reliably prevented.

  Further, since the guide surface side protruding portion 57 provided on the guide surface 31c side of the outer rail portion 31 is set lower than the height of the opposite surface side protruding portion 52, the game ball B along the guide surface 31c is provided. Can be prevented from being obstructed by the guide surface side protruding portion 57. When the game ball B interferes with the guide surface side projecting portion 57, the kinetic energy of the game ball B is lost, and the flight distance of the game ball B guided to the game area PE becomes unstable, but this can be prevented. 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 slit shape from the distal end (the lower side in FIG. 14) of the fitting convex portion 55 except for the base end (the proximal end portion 55b) of the solid fitting convex portion 55. Is formed. Thereby, the base end portion 55b of the solid fitting projection 55 can be fitted into the hole 69 (board side). By fitting the base end 55b of the solid fitting projection 55 into the hole 69 (board side), it is possible to prevent the fitting projection 55 from rattling with the hole 69. Further, since the concave portion 56 is formed on the tip end side of the fitting convex portion 55, the fitting convex portion 55 or the hole 69 can be easily elastically or plastically deformed. 69 can be easily fitted.

  The gap between the outer peripheral surface of the fitting convex portion 55 (the base end portion 55b) and the hole portion 69 is formed by the groove 58 between the opposite surface side protruding portion 52 and the guide surface side protruding portion 57. It is set to a value smaller than the gap between the rail portion 31 and the projecting portion 52 on the opposite surface side or the projecting portion 57 on the guide surface side. While the fitting projection 55 (base end 55b) fitted in the hole 69 is prevented from rattling, when the outer rail portion 31 is fixed to the game board 30, the opposite surface side projecting portion 52 and the guide are provided. This is for facilitating the insertion of the outer rail portion 31 into the groove portion 58 between the surface side projecting portions 57. In addition, even if a gap is formed between the opposite surface side protruding portion 52 or the guide surface side protruding portion 57 and the outer rail portion 31, the outer rail portion 31 is fixed to the game board 30 by the fitting pin 31a. The play 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 that regulates the tilting of the outer rail portion 31 includes the fitting protrusion 55 that fits into the hole 69 formed in the recessed surface of the game board 30, and the fitting protrusion 55. A protruding portion 52 that protrudes from the portion 55 and contacts the opposite surface of the outer rail portion 31 from the guide surface 31c. The guide portion reinforcing member 50 is formed on the opposite surface side protruding portion in which the fitting convex 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 fitting convex portion 55 is provided. 52 contacts the opposite side of the guide surface 31c of the outer rail portion 31. Accordingly, it is possible to prevent the guide surface 31c from being pushed to the opposite surface side and the belt-shaped outer rail portion 31 from tilting outward due to a game ball traveling toward the game area PE along the guide surface 31c. Since the 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 proceeding 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 changes or the game ball changes. Or a 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, the guide surface reinforcing member 50 is arranged such that the opposite surface side protruding portion 52 is in contact with the opposite surface of the outer rail portion 31 from the guide surface 31c, so that the guide surface is provided. It is possible to suppress the outer rail portion 31 from tilting due to a game ball traveling toward the game area PE along 31c. Thereby, the trajectory and flight distance of the game ball guided to the game area PE can be stabilized.

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

  Further, since the concave portion 56 is formed in a slit shape from the distal end of the fitting convex portion 55 toward the base end (the base end portion 55b), the elastic deformation of the fitting convex portion 55 due to the sliding is utilized. The fitting projection 55 can be fitted into the hole 69. As a result, the fitting projection 55 can be easily fitted into the hole 69, and a gap is prevented from being formed between the hole 69 and the fitting projection 55 by utilizing the elastic deformation of the fitting projection 55. Since it is possible, the fitting protrusion 55 fitted into the hole 69 can be made less likely to rattle.

  In addition, since the direction of the sliding of the concave portion 56 as viewed from the axial direction of the fitting convex portion 55 is arranged non-parallel to the longitudinal direction of the outer rail portion 31, along the guide surface 31 c of the strip-shaped outer rail portion 31. When the guide surface 31c is pushed to the opposite side by the game ball which advances toward the game area PE, the fitting convex portion 55 can be hardly elastically deformed. Thereby, it can suppress that the outer rail part 31 inclines. As a result, the trajectory and flight distance of the game balls 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. Thereby, the tilting of the outer rail portion 31 can be reliably prevented. As a result, the trajectory and flight distance of the game balls guided to the game area PE can be further stabilized. Further, since the guide surface side projecting portion 57 is set lower than the height of 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. it can.

  Also, the opposite surface side protruding portion 52 is provided with an inclined portion 52 a which is inclined downward from the top toward the outside in the axial direction of the fitting convex portion 55, and is provided continuously with the inclined portion 52 a and opposite to the outer rail portion 31. 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 and the outer rail portion 31 can be easily arranged on the board surface of the game board 30.

  That is, when arranging the guide portion reinforcing member 50 and the outer rail portion 31 on the board surface of the game board 30, first, about half the length of the fitting convex portion 55 of the guide portion reinforcing member 50 is reduced. Insert into the hole 69. Since the fitting projection 55 has a slot-shaped recess 56, when the slot is inserted into the hole 69 of the game board 30, the fitting projection 55 is formed so as to reduce the interval between the slot-shaped recesses 56. Deform. Therefore, the work of inserting about half the length of the fitting projection 55 into the hole 69 of the game board 30 can be facilitated.

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

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

  Since the base end 55b of the fitting projection 55 is formed in a solid shape, the base end 55b is fitted into the hole 69. Thereby, it is possible to prevent the fitting protrusion 55 from rattling in the hole 69.

  Further, the projection 69a is protruded toward the rear side from the thin portion 72 of the game board 30, and the hole 69 is formed through the projection 69a and the thin portion 72 so that the projection 69a is fitted into the hole 69. The fitting depth of the fitting projection 55 can be secured. 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 a direction orthogonal to the axial direction. Since the fitting depth of the fitting projection 55 fitted into the hole 69 is ensured, the guide portion reinforcing member 50 fixed to the game board 30 can be made difficult to swing. By making the guide portion reinforcing member 50 fixed to the game board 30 difficult to swing, the tilting of the outer rail portion 31 that guides the game ball to the game area PE can be suppressed, so that the game ball guided to the game area PE Orbit and flight distance can be further stabilized.

  Further, since the projecting portion 69a is coupled to the thin portion 72 and the hole 69 is formed through the projecting portion 69a and the thin portion 72, it is necessary to increase the area of the thick portion 70 in order to form the hole 69. Can be unnecessary. Although the mass of the game board 30 is increased by the protrusion 69 a (excluding the hole 69) coupled to the thin portion 72, it is not necessary to increase the area of the thick portion 70. The increase can be suppressed. Further, the projection 69 a formed with the hole 69 therethrough functions as a rib for increasing the rigidity of the thin portion 72 around the hole 69, so that the rigidity of the thin portion 72 around the hole 69 can be secured. Therefore, a nail can be implanted in the thick portion 70 to secure the holding force of the nail, and the game board 30 can be reduced in weight while securing the rigidity of the game board 30. In addition, the trajectory and flight distance of the game ball guided to the game area PE can be further stabilized.

  Next, a guide portion reinforcing member 50 according to another embodiment will be described with reference to FIG. The same parts as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. FIG. 15A is a partially enlarged rear view of a game board 30 provided with a guide portion reinforcing member 80 according to another embodiment, and FIG. 15B is a game provided with a guide portion reinforcing member 90 according to another embodiment. It is a partial enlarged rear view of the board 30. 15 (a) and 15 (b), fitting protrusions 85, 95 of guide portion reinforcing members 80, 90 are fitted into holes 69 formed in game board 30 from the board surface (front) side. Then, a state viewed from the back side of the game board 30 is illustrated.

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

  A concave notch 85 a having a circular cross section is formed substantially at the center of the fitting protrusion 85 along the axial direction of the fitting protrusion 85 from the tip of the fitting protrusion 85. By reducing the cross-sectional area of the fitting projection 85 by the concave notch 85a, the fitting projection 85 can be easily elastically deformed by the vertical force acting on the fitting projection 85. Thereby, the fitting protrusion 85 can be more easily fitted into the hole 69, so that the workability when fitting the fitting protrusion 85 into the hole 69 can be improved. Further, by making the fitting projection 85 easily elastically deform, it is possible to prevent the fitting projection 85 from rattling with the hole 69.

  In particular, since the concave portion 86 is formed in such a shape that two portions are cut out along the axial direction of the fitting convex portion 85, the outer peripheral surface of the fitting convex portion 85 is prevented from being excessively small, A contact area with the inner peripheral surface of the hole 69 can be secured. Since the vertical effect per unit area of the outer peripheral surface of the fitting convex portion 85 can be prevented from being excessive, deformation such as buckling of the outer peripheral surface of the fitting convex portion 85 can be suppressed. Thereby, it is possible to suppress a problem that a gap is formed between the outer peripheral surface of the fitting convex portion 85 and the inner peripheral surface of the hole portion 69, and the fitting convex portion 85 is loose.

  The guide portion reinforcing member 90 shown in FIG. 15B has a portion of the outer peripheral surface at four axially symmetrical positions on the outer peripheral surface of the fitting projection 95 along the axial direction (perpendicular to the paper surface of FIG. 15B). Is provided with a concave portion 96 formed in a concave shape. Since the fitting protrusion 95 has the concave portion 96 in which a part of the outer peripheral surface is formed in a concave shape, the outer peripheral surface of the fitting protrusion 95 when the fitting protrusion 95 is fitted into the hole 69. The contact area between the hole and the inner peripheral surface of the hole 69 can be reduced. As a result, the vertical effectiveness per unit area of the hole 69 and the fitting protrusion 95 when the fitting protrusion 95 is fitted into the hole 69 can be increased. Thereby, when the fitting projection 95 is fitted into the hole 69, the hole 69 or the fitting projection 95 can be easily deformed (elastic deformation or plastic deformation). It can be easily fitted into the hole 69.

  At the approximate center of the fitting projection 95, a concave notch 95a having a circular cross section is formed 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 by the concave notch 95a, the fitting projection 95 can be easily elastically deformed by the vertical effect acting on the fitting projection 95. Thereby, the fitting projection 95 can be more easily fitted into the hole 69, so that the workability when fitting the fitting projection 95 into the hole 69 can be improved. Furthermore, by making the fitting projection 95 easily elastically deform, it is possible to prevent the fitting projection 95 from rattling with the hole 69.

  Next, a second embodiment will be described with reference to FIG. In the first embodiment, the outer peripheral edge of the opening 61 penetratingly formed in the thickness direction of the game board 30 is continuous inside the outer peripheral edge of the game board 30 (the outer peripheral edge of the game board 30 is closed). The case has been described. On the other hand, in the second embodiment, a case will be described in which the opening 161 is formed to penetrate in the thickness direction of the game board 130 and a part of the outer peripheral edge of the game board 130 is opened. The same parts as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. FIG. 16 is a front view of a game board 130 and a structure 170 which are 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 so as to penetrate in the thickness direction of the game board 130 (perpendicular to the paper surface of FIG. 16) and partially opening the outer peripheral edge of the game board 130. And a structure 170 for connecting the peripheral edges of the opening 161 to each other. In the present embodiment, a part of the outer peripheral edge of the game board 130 located on the right side when viewed from the front is opened by the opening 161. By forming the opening 161, the 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 of the periphery of the opening 161 of the game board 130. In the present embodiment, the structure 170 is formed in a substantially rectangular shape when viewed from the front, and connects two portions of the opening 161 along the outer peripheral edge of the game board 130. The game board 130 and the structure 170 are formed of a light-transmitting synthetic resin, similarly to the game board 30 described in the first embodiment. A symbol display device 43a (see FIG. 5) is arranged inside the opening 161 in which a part of the outer peripheral edge is closed by the structure 170, as in the first embodiment.

  Next, a connection structure between the game board 130 and the structure 170 will be described with reference to FIG. FIG. 17 is a perspective view of the game board 130 and the structure 170. 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 has a main body 172 formed in a substantially rectangular parallelepiped box shape, and protrudes from the front side of the main body 172 on both sides up and down (in a direction substantially parallel to the board surface of the game board 30). It mainly comprises an engagement portion 171 formed in a flange shape.

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

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

  In the game board 130, a connecting portion (engaged portion) 131 that receives the engaging portion 171 provided on the structure 170 is formed at a part of the periphery of the opening 161. The connection part 131 is a part for positioning the structure 170 by engaging with the engagement part 171 provided on the structure 170.

  In the present embodiment, the connecting portion 131 is provided as a step-shaped flat surface that is 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 gaming board 130 (in the left-right direction in FIG. 17) is set substantially equal to the thickness of the engaging portion 171 (in the left-right direction in FIG. 17).

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

  The connecting portion 131 is formed with an insertion hole 133 through which an insertion hole 174 formed in the structure 170 (engaging portion 171) is connected in the axial direction, into which a shaft 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 by a shaft-like member such as a screw that is screwed into the insertion holes 133 and 174.

  Next, the light scattering section 132 will be described with reference to FIG. The light scattering portion 132 is formed on the rear side of the connecting portion 131 as a ridge or a projecting portion. A support 180 is provided 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.

  The light (indicated by a two-dot chain line in FIG. 18) emitted from the light emitting portion 181 enters and exits the light scattering portion 132 (the engaged portion 131) due to the difference in refractive index between the air and the light scattering portion 132. Sometimes refracted. Therefore, if the light emitting section 181 emits light, it is possible to realize an electric decoration in a state where a large number of lights are dispersed or a state with a three-dimensional effect. Thereby, in addition to the effect produced by the symbol display unit 173 (decorative portion), the effect produced by the light from the light emitting unit 181 can be improved.

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

  Also, when the light scattering portion 132 is provided by processing the board surface (surface) of the game board 130 into a ridge or projection, the unevenness of the light scattering portion 132 interferes with the movement of the game ball, In the case where the light scattering portion 132 is provided on the back surface (back surface) of the game board 130, it is not necessary to consider the interference of the movement of the game ball by the light scattering portion 132 (unevenness). Thereby, the flexibility of the design of the game board 130 can be ensured.

  When the light scattering portion 132 is provided on the back side (back surface) of the game board 130 (the connecting portion 131), the shape of the light scattering portion 132 can be designed relatively freely. The outer peripheral edge of the gaming board 130 is provided with an outer peripheral reinforcing rib 73 (see FIG. 17) standing up toward the rear side. This is because space can be secured.

  In addition, the light scattering part 132 scatters light, so that a shadow of a shaft-like member (not shown) such as a screw inserted into the insertion holes 133 and 174 is cast from the board surface of the game board 130 and the front face of the structure 170. It can be prevented from being visually recognized. This is because the light can be scattered in front of the shaft member (not shown) by scattering the light by the light scattering section 132. This makes it difficult to visually recognize the joint (the connecting portion 131 and the engaging portion 171) between the game board 130 and the structure 170 due to the light scattered by the light scattering section 132, and also allows the game board 130 and the structure 170 The staging effect can be improved.

  According to the pachinko machine 1 configured as described above, the opening 161 penetratingly formed in the thickness direction of the game board 130 has a part of the outer peripheral edge of the game board 130 opened, and the peripheral edge of the opening 161 has two edges. The points are connected by the structure 170. Thereby, the structure 170 can be made three-dimensional using a space in the thickness direction of the game board 130. Since the structure 170 includes the symbol display portion 173 (decorative portion), a three-dimensional effect using a space in the thickness direction of the game board 130 can be implemented. Thereby, the interest of the game can be greatly enhanced.

  Here, in a conventional structure in which components such as a display device and an accessory are attached to the surface of a game board, since the spread in the depth direction is poor, similar effects are easily adopted, and it is difficult to enhance the interest of the game. Also, in the conventional game board made of wooden plywood (veneer), in consideration of the workability and mechanical strength of the wooden plywood, a structure in which an opening for opening a part of the outer peripheral edge of the game board is adopted. hard.

  On the other hand, according to the present embodiment, by using the game board 130 made of a synthetic resin in which the opening 161 that opens a part of the periphery (the periphery reinforcement rib 73) is formed, the game board 130 is formed. A three-dimensional structure 170 using a space in the thickness direction can be adopted. As a result, a three-dimensional effect utilizing the space in the thickness direction of the game board 130 can be implemented. Thereby, the interest of the game can be greatly enhanced.

  In addition, a symbol display device 43a (see FIG. 5) having a display unit for variably displaying symbols is provided in the opening 161 and the structure 170 is arranged around the symbol display device 43a. By the symbol display unit 173 (decorative portion) of 170, not only a two-dimensional symbol effect of the symbol display device 43a but also a three-dimensional effect using the space in the thickness direction of the game board 130 can be realized. Further, since the structure 170 is unitized as a game component having the symbol display portion 173 (decorative portion), it is possible to easily mount the structure 170 on the game board 130, exchange work, and the like.

  Next, a game board 130 and a structure 190 in another embodiment will be described with reference to FIGS.

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

  A game ball launching device for launching a game ball, a game board made of synthetic resin forming a game area in which a game ball fired by the game ball launching device flows down, and the game ball launching device arranged on the board of the game board And a belt-shaped guide portion for guiding a game ball fired by the device to the game area along a guide surface, comprising a guide portion reinforcing member fixed to the board surface of the game board, and reinforcing the guide portion. The member has a fitting protrusion fitted into a recess formed in the board surface of the game board, and a member protruding from the fitting protrusion and contacting the opposite side of the guide surface of the guide portion. A gaming machine A1 comprising: a protruding portion on the opposite side.

  According to the gaming machine A1, a game area in which a game ball fired by the game ball firing device flows is formed by a game board made of synthetic resin. On the board of the game board, a belt-like guide portion for guiding a game ball fired by the game ball launching device to a game area along a guide surface is arranged. A guide reinforcing member is fixed to the board surface of the game board. The guide portion reinforcing member is configured such that a fitting protrusion fits into a hole formed in a recessed shape on the board surface of the game board, and a projecting portion on the opposite surface protrudingly provided in the fitting protrusion guides the guide portion. Contact the opposite side of the surface. Accordingly, it is possible to suppress the tilting of the belt-shaped guide portion due to the guide surface being pushed to the opposite surface side by the game ball proceeding toward the game area along the guide surface. Since the tilting of the guide portion for guiding 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 surface side by the game ball traveling toward the game area along the guide surface and the belt-shaped guide portion tilts, the trajectory of the game ball changes or the kinetic energy of the game ball is lost. May occur. As a result, the trajectory and flight distance of the game ball guided to the game area may become unstable.

  On the other hand, according to the gaming machine A1, by arranging the guide portion reinforcing member so that the opposite surface side protruding portion contacts the opposite surface of the guide surface of the guide portion, the game area is extended along the guide surface. It is possible to suppress the guide portion from tilting due to the game ball traveling toward. Thereby, the trajectory and flight distance of the game ball guided to the game area can be stabilized.

  The gaming machine A2 according to the gaming machine A1, wherein the fitting projection has a concave portion in which a part of an outer peripheral surface is formed in a concave shape.

  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 when the fitting convex portion is fitted into the hole portion is formed. The contact area with the inner peripheral surface of the hole can be reduced. As a result, it is possible to increase the vertical effectiveness per unit area of the hole and the fitting protrusion when the fitting protrusion is fitted into the hole. This makes it easy to deform (elastic deformation or plastic deformation) the hole or the fitting protrusion when the fitting protrusion is fitted to the hole. There is an effect that the mating projection can be easily fitted into the hole.

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

  According to the gaming machine A3, since the concave portion is formed in a sliding manner from the distal end to the base end of the fitting convex portion, the fitting portion is fitted into the hole portion by utilizing the elastic deformation of the fitting convex portion due to the sliding. The mating projections can be fitted. As a result, in addition to the effect of the gaming machine A1 or A2, the fitting protrusion can be easily fitted into the hole, and the hole and the fitting protrusion can be formed by utilizing the elastic deformation of the fitting protrusion. Since the formation of the gap can be prevented, there is an effect that the fitting protrusion fitted in the hole can be made less likely to rattle.

  In the gaming machine A3, the guide portion reinforcing member may be arranged such that a direction of the groove of the concave portion viewed from an axial direction of the fitting convex portion is not parallel to a longitudinal direction of the guide portion. Gaming machine A4.

  According to the gaming machine A4, since the guide portion reinforcing member is arranged in such a manner that the sliding direction of the concave portion viewed from the axial direction of the fitting convex portion is not parallel to the longitudinal direction of the guide portion, the guide of the belt-shaped guide portion is provided. When the guide surface is pushed to the opposite surface side by a game ball which advances toward the game area along the surface, the fitting convex portion can be hardly elastically deformed. Thereby, it can suppress that a guide part tilts. As a result, in addition to the effect played by the gaming machine A3, there is an effect that the trajectory and flight distance of the game ball guided to the game area can be further stabilized.

  That is, the fitting convex portion is not easily elastically deformed by a load parallel to the sliding direction, and is easily elastically deformed by a load orthogonal to the sliding direction. Therefore, if the guide portion reinforcing member is arranged so that the sliding direction of the fitting protrusion is parallel to the longitudinal direction of the guide portion, when the guide surface of the guide portion is pushed to the opposite surface side, the fitting protrusion is formed. The guide portion is easily tilted by the elastic deformation of the portion. On the other hand, if the guide portion reinforcing member is arranged so that the sliding direction 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 surface side, The fitting projection can be made less likely to be elastically deformed. This makes it difficult to tilt the guide portion toward the opposite surface side of the guide surface.

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

  According to the gaming machine A5, the guide surface side protrusion provided on the guide surface side of the guide portion facing the opposite surface protrusion portion comes into contact with the guide surface of the guide portion. The guide portion is held between the portion and the guide surface side protruding portion. Since the guide portion is held from both the guide surface and the opposite surface by the guide portion reinforcing member, the tilting of the guide portion can be reliably prevented in addition to the effect of any of the gaming machines A1 to A4. As a result, there is an effect that the trajectory and flight distance of the game ball guided to the game area can be further stabilized.

  Also, since the guide surface side protruding portion provided on the guide surface side of the guide portion is set lower than the height of the opposite surface side protruding portion, the progress of the game ball along the guide surface is guided by the guide surface side protruding portion. The installation can be prevented from interfering. When the game ball interferes with the guide surface side protruding portion, the kinetic energy of the game ball is lost and the flight distance of the game ball guided to the game area becomes unstable. This can be prevented, so the guide to the game area can be prevented. It is possible to prevent the flying distance of the played game ball from becoming unstable.

  In any one of the gaming machines A1 to A5, the opposite surface-side protruding portion is provided with an inclined portion inclined downward from the top toward the fitting convex portion side, and is connected to the inclined portion and the guide portion is provided. A gaming machine A6 comprising: a contact portion facing at least a part of the opposite surface while facing the opposite surface.

  According to the gaming machine A6, when the guide portion reinforcing member and the guide portion are arranged on the board surface of the game board, first, the fitting convex portion of the guide portion reinforcing member is inserted into the hole of the game board. Next, the guide portion is arranged along the inclined portion of the protruding portion on the opposite surface side such that the opposite surface faces the contact portion of the guide portion reinforcing member. The inclined portion is inclined downward from the top toward the fitting convex portion, and the contact portion is provided continuously with the inclined portion, so that the guide portion can be smoothly arranged along the inclined portion to the contact portion. it can. Thus, in addition to the effect of any one of the game boards A1 to A5, the guide portion can be smoothly arranged on the board surface of the game board, and the effect of improving the workability of arranging the guide portion on the board surface can be improved. is there.

  In any one of the gaming machines A1 to A6, the gaming board is located on the back side of the gaming area, and a nail is implanted on the board surface. A thin portion having a thickness smaller than that of the thin portion, an outer peripheral edge reinforcing rib erected from the outer peripheral edge of the thin portion to the rear side, and a projection formed by projecting rearward from a predetermined portion of the thin portion. A gaming machine A7, characterized in that the gaming machine A7 includes a hole, and the hole is formed through the thin portion and the protruding portion.

  According to the gaming machine A7, since the nails are implanted on the wall of the thick portion located on the back side of the game area in the gaming machine A7, the nail holding force can be secured by securing the nail driving depth. In addition, since a thin portion having a thickness smaller than that of the thick portion is connected to the thick portion, a game board having no thin portion (game board formed uniformly with the thickness of the thick portion) The game board can be reduced in weight as compared with. Further, since the outer peripheral edge reinforcing ribs are provided upright 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, the game board can be reduced in weight while securing rigidity, and the holding power of nails implanted on the board surface can be increased.

  In addition, since the protruding portion is connected to the thin portion and protrudes from the predetermined portion to the back side, and the hole is formed through the thin portion and the protruding portion, the fitting of the fitting protrusion fitted into the hole is performed. The depth can be secured. As the fitting depth of the fitting projection fitted into the hole increases, the fitting projection fitted into the hole tends to be less likely to swing in a direction orthogonal to the axial direction. By ensuring the fitting depth of the fitting projection fitted into the hole, the guide portion reinforcing member fixed to the game board can be made difficult to swing. By making it difficult for the guide portion reinforcing member fixed to the game board to swing, the tilt of the guide portion for guiding the game ball to the game area can be suppressed, so that the trajectory and flight distance of the game ball guided to the game area can be reduced. Further stabilization is possible.

  In addition, since the projecting portion is formed by projecting from the predetermined portion of the thin portion to the back side and connecting the projecting portion, and the hole is formed through the projecting portion and the thin portion, the area of the thick portion is increased to form the hole. Can be eliminated. The mass of the game board increases by the protruding portion (excluding the hole) coupled to the thin portion, but 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 protrusion having the hole formed therethrough exhibits a rib function of increasing the rigidity of the thin portion around the hole, the rigidity of the thin portion around the hole can be secured.

  As described above, according to the gaming machine A7, in addition to the effect of any one of the gaming machines A1 to A6, the game board can be reduced in weight while securing the rigidity of the game board, and the holding of nails implanted on the board surface can be achieved. In addition to being able to increase the power, there is an effect that the trajectory and flight distance of the game ball guided to the game area can be further stabilized.

  A game board made of a synthetic resin forming a game area in which game balls flow down, an opening formed through the game board in a thickness direction thereof, and a part of an outer peripheral edge of the game board being opened; And a structure arranged in the section, wherein the structure includes a member that interferes with the movement of the game ball, a member that the game ball passes through, or a member that is used for announcement and production of the game. Gaming machine B1.

  According to the gaming machine B1, a game area in which a game ball flows down is formed by a game board made of synthetic resin, and an opening is formed through the game board in a thickness direction thereof. In the opening, a part of the outer peripheral edge of the game board is opened, and in the opening, a structure as a member that interferes with the movement of the game ball, a member through which the game ball passes, or a member used for announcement or production of a game. Be placed. As a result, the structure can be arranged less likely to be restricted by the game board. As a result, there is an effect that the degree of freedom of the game effect can be improved, and the interest of the game can be greatly enhanced.

  That is, conventionally, as this type of gaming machine, a pachinko machine in which a game ball is fired at a game area and a predetermined number of game balls are paid out when a game ball is won at various winning ports in the game area. is there. In a pachinko machine, for example, a symbol display unit such as a liquid crystal display device is arranged at the center of the game area, and symbols in a plurality of rows are variably displayed by the symbol change unit. The symbol display by the symbol display unit is started by the winning of the predetermined winning opening (start winning opening) as a trigger, and thereafter, the variable display of the symbol is stopped via the variable display by the predetermined variation pattern. When the stopped symbol is determined, if the combination of the symbols is a predetermined combination set in advance, the game shifts to a special game state (big hit state) and a large amount of game balls are paid out.

  In recent years, in order to enhance the interest of the game, the display contents displayed on the display screen of the liquid crystal display device are complicated, or the display screen is enlarged to improve the power of the display image, and so on. Various ideas have been applied. However, the impression given to the player tends to be similar even if various measures are taken for the symbol display. In order to attract the player's interest, it is necessary to adopt a new structure and perform a new production by the structure.

  However, in a conventional structure in which parts such as a display device and an accessory are attached to the surface of a game board, similar effects are likely to be adopted since the depth direction is poor. In addition, in a game board made of conventional wooden plywood (veneer), it is difficult to adopt a new structure in consideration of workability and mechanical strength.

  On the other hand, according to the gaming machine B1, by using a synthetic resin game board having an opening formed by opening a part of the peripheral portion, the structure of the game board is less likely to be restricted. can do. As a result, the degree of freedom in producing a game can be improved. Thereby, there is an effect that the interest in the game can be greatly enhanced.

  The gaming machine B1, further comprising a symbol display device provided in the opening and having a display portion for variably displaying symbols, wherein the structure is arranged around the symbol display device. B2.

The plurality of printing portions are provided with a difference in light transmission, and opaque portions having no light transmission are also provided. Thus, when light is irradiated from the back side of the game board 30 toward the game board 30, light and darkness is generated in the printing section due to a difference in translucency of the printing section, so that the rendering effect can be enhanced.

  Next, the game board 30 will be described with reference to FIGS. FIG. 6 is a front view of the game board 30, and FIG. 7 is a rear view of the game board 30. 6 and 7 show a state before a pilot hole (a screw insertion hole) into which a screw or the like is inserted and a pilot hole (a nail insertion hole) into which a nail or a windmill is driven are drilled in the game board 30. 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 port) 36 is attached, the opening 66 is a through hole to which a winning opening 37 is attached, and the opening 67 is a general winning opening 38 to be attached. Through hole.

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

  As shown in FIG. 7, the game board 30 is located at a substantially central portion on the back surface of the game board 30 and has a thick portion 70 whose outer shape in a rear view is formed in a substantially circular shape, and is formed around the thick portion 70. A slanted surface portion 71 having a substantially circular outer shape in a rear view, a thin portion 72 formed around the slanted surface portion 71 and having a substantially rectangular outer shape in a rear view, and a periphery of the thinned portion 72 And a peripheral edge reinforcing rib 73 erected at the bottom.

  Next, a cross-sectional shape of the game board 30 will be described with reference to FIG. FIG. 8 is a sectional end view of the game board 30 taken along the line VIII-VIII in FIG. As shown in FIG. 8, the game board 30 is formed with a flat surface on the board side (the front side, the lower side in FIG. 8), and the thick portion 70 is formed on the back side (the upper side in FIG. 8), and the thickness is reduced. It is set almost constant. The inclined surface portion 71 is formed continuously with the thick portion 70 and is formed so that the plate thickness becomes gradually smaller as approaching the periphery of the game board 30 (toward the outer periphery). The thin portion 72 is provided continuously around the inclined surface portion 71 and has a thickness smaller than the thickness 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 provided continuously around the thin portion 72, and projects rearward from the outer peripheral edge of the thin portion 72. In addition, since the height (vertical direction in FIG. 8) of the outer peripheral edge reinforcing rib 73 is set to a value larger than the thickness of the thick portion 70, the game board 30 needs to be externally attached to the resin base 20 of the main body frame 3. When the rear end portion of the peripheral edge reinforcing rib 73 is brought into contact with the front surface of the resin base 20, the thick portion 70 can be prevented from interfering with the resin base 20.

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

  Further, in the game board 30, since the thickness of the thick portion 70 is set to be smaller than the height of the outer peripheral edge reinforcing ribs 73, the game board 30 has a uniform thickness in which the height of the outer peripheral edge reinforcing ribs 73 is the thickness. It can be lighter than a board. A space can be provided on the back side of the thick portion 70 by the thickness of the thick portion 70 set to be smaller than the height of the outer peripheral edge reinforcing ribs 73, so that decorations and the like are arranged in the space on the back side. It is possible to do. Since a light-emitting element such as an LED can be arranged in the space on the back side, the effect can be improved.

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

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

  An inclined surface portion 71 is formed on the outer periphery of the thick portion 70. The inclined surface portion 71 is set so that the thickness is gradually reduced from the thick portion 70 toward the outside, and is connected to the thin portion 72. Thereby, at the time of forming the game board 30, it is possible to suppress the occurrence of deformation due to the difference in thickness between the thick portion 70 and the thin portion 72. That is, the game board 30 is molded by melting and filling a cavity of a molding die with a synthetic resin, and after curing, a molded body is taken out from the molding die. Since the cooling rate of the compact is higher in the thinner portion 72 having a smaller thickness than in the thicker portion 70 having a larger thickness, residual stress is generated due to the difference in cooling rate, and the game board 30 is liable to be deformed such as warpage. However, the generation of the residual stress due to the difference in the cooling rate can be buffered by the inclined surface portion 71 coupled between the thin portion 72 and the thick portion 70. As a result, deformation such as warpage of the game board 30 can be suppressed.

  The hole 68 formed at the boundary between the thick portion 70 and the inclined surface 71 is a portion into which a fitting pin (described later) spot-welded to the inner rail 32 is fitted. The hole 68 formed on the outer peripheral side of the game board 30 from the boundary between the thick part 70 and the inclined surface part 71 and formed in the thin part 72 and the peripheral part reinforcing rib 73 is spot-welded to the outer rail part 31. This is a portion where a mating pin (described later) is inserted. The hole 68 is provided with a cylindrical protrusion 68a standing upright 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 68 a is formed around the hole 68, the plate thickness around the hole 68 can be increased. As a result, the load per unit area applied by the fitting pin to the inner periphery of the hole 68 can be reduced, so that cracks around the hole 68 (particularly, the thin portion 72) can be hardly generated. Further, since the depth of the hole 68 (the front-rear direction of the game board 30) can be increased by the protruding portion 68a, the holding force of the fitting pin can be increased. 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 projection 68a (hole 68) into which a fitting pin spot-welded to the inner rail portion 32 is inserted is formed at a boundary between the thick portion 70 and the inclined surface portion 71, and a thick portion is formed on the outer periphery of the projection 68a. The portion 70 and the inclined surface portion 71 are provided continuously. Since the thickness of the thick portion 70 and the inclined surface 71 is greater than the thickness of the thin portion 72, the projecting length of the projecting portion 68 a with respect to the thick portion 70 and the inclined surface 71 is larger than the projecting length of the projecting portion 68 a with respect to the thin portion 72. Can be smaller. As a result, the bending moment of the protruding portion 68a with respect to the thick portion 70 and the inclined surface portion 71 can be made smaller than the bending moment of the protruding portion 68a with respect to the thin portion 72. The bending strength of the projection 68 a protruding from the thin portion 72 can be improved.

  In addition, a fitting pin spot-welded to the inner rail 32 is inserted into a hole 68 formed in a protrusion 68a formed at a boundary between the thick part 70 and the inclined surface part 71. By providing the thick portion 70 inside the inner rail portion 32 where the game area PE is formed, it is possible to secure a holding force for nails, windmills, and the like. By providing a projection 68a (hole 68) into which a fitting pin spot-welded to the inner rail portion 32 is inserted at a boundary between the thick portion 70 and the inclined surface portion 71, the area of the thick portion 70 becomes excessive. Can be prevented from increasing. By preventing the thick portion 70 from expanding outside the region (in the inner rail portion 32) where the game region 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. Unnecessarily large size can be prevented.

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

  The hole 69 is a portion into which a fitting convex portion (described later) of the guide portion reinforcing member 50 is fitted, and is formed through the thin portion 72. Since the protrusion 69 a is formed around the hole 69, the plate thickness around the hole 69 can be increased. As a result, the load per unit area applied by the fitting projection to the inner periphery of the hole 69 can be reduced, so that cracks around the hole 69 (thin portion 72) can be less likely to occur. In addition, since the depth of the hole 69 (the front-rear direction of the game board 30) can be increased by the protrusion 69a, the holding force of the fitting projection can be increased. Thereby, 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 provided with recessed portions 73a, 73b, 73c in which a part of the end face on the back side (front side in FIG. 7) is recessed in the height direction (the height of the rib is reduced). . The concave portions 73a and 73c are formed at positions facing the outer peripheral edge reinforcing ribs 73 (left and right ribs), and the concave portions 73b intersect with the outer peripheral edge reinforcing ribs 73 (left and right ribs) where the concave portions 73a and 73c are formed. It is formed on the outer peripheral edge reinforcing rib 73 (lower rib). Since the recessed portions 73a and 73c are formed at positions opposed to the outer peripheral edge reinforcing ribs 73, the molded game board 30 is placed on a base having a flat surface formed on the upper surface with the outer peripheral edge reinforcing ribs 73 downward. In the case where the game board 30 is placed with its back side facing down, there is a gap between the flat surface and the game board 30 (the outer peripheral edge reinforcing rib 73) by the amount of the recesses 73a and 73c. A fingertip or the like of a hand can be inserted into the gap, and the gaming board 30 placed on a flat surface can be lifted using the inserted fingertip or the like as a clue.

  On the other hand, when the concave portions 73a, 73b, and 73c are not formed on the rear end surface of the outer peripheral edge reinforcing rib 73, the outer peripheral edge reinforcing rib 73 is placed on a base having a flat surface formed on the upper surface. When the game board 30 is placed with the rear side facing downward, the entire periphery of the rear side end face of the outer peripheral edge reinforcing rib 73 comes into close contact with a flat surface (a gap cannot be formed). In such a case, it is difficult to insert a fingertip or the like between the outer peripheral edge reinforcing rib 73 and the flat surface (table), so that there is 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 recesses 73a, 73b, 73c in the outer peripheral edge reinforcing rib 73.

  The openings 62 are through holes to which the protruding pins 60 are attached, and are formed at two diagonal positions of the game board 30. A reinforcing rib 62a is provided upright 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 and 62a and the protrusions 68a and 69a are set to be substantially the same as the height of the peripheral edge reinforcing rib 73. Thereby, in a state where the game board 30 is placed on the base having a flat surface formed on the upper surface with the outer peripheral edge reinforcing ribs 73 facing down (back side facing down), 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 and 62a, the protrusions 68a and 69a, and the peripheral edge reinforcing rib 73.

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

  In particular, the protrusions 68a for fixing the outer rail portion 31 and the inner rail portion 32 are located on a substantially semi-annular line and are widely scattered on the game board 30. Even when a concentrated load is applied to the game board 30, large bending deformation can be prevented from being generated on the board surface of the game board 30. This prevents the game board 30 from being damaged by the load applied to the game board 30 when a nail is planted in the game board 30 or various game parts are attached.

  Next, the opening 62 and the protruding pin 60 will be described with reference to FIG. FIG. 9 is a sectional end view of the gaming board 30 along the line IX-IX in FIG. As shown in FIG. 9, the protruding pin 60 is a substantially columnar member formed of a member separate from the game board 30, and has a flange portion 60 a projecting radially from the outer peripheral surface (the horizontal direction in FIG. 9). A fitting insertion portion 60b extending from the flange portion 60a to the other axial side is continuously provided. The insertion portion 60b is a portion that is inserted into the opening 62, and the flange portion 60a is a portion that regulates the insertion depth of the insertion portion 60b that is inserted into the opening 62. On the other hand, a recess 62b for receiving the flange 60a is formed on the board surface of the game board 30. The concave portion 62b is continuously provided around the opening 62 at substantially the same depth as the thickness of the flange portion 60a. 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).

  The end face of the reinforcing rib 62a on the back side (lower side in FIG. 9) is set at substantially the same height position as the end face on the back side (lower side in FIG. 9) of the peripheral edge reinforcing rib 73. Thus, the depth of the opening 62 (vertical direction in FIG. 9) can be increased, so that the insertion depth at which the insertion portion 60b is inserted into the opening 62 can be increased. On the other hand, when the reinforcing ribs 62 a are not formed, the depth of the opening 62 is the same as the thickness of the thin portion 72. In this case, the holding force for holding the fitting portion 60b in the opening 62 is smaller than in the present embodiment, and the protruding pin 60 is likely to rattle or come off. By providing the reinforcing rib 62a as in the present embodiment, it is possible to prevent that.

  Further, since the game board 30 in which the fitting portion 60b is inserted into the opening 62 has the flange 60a, the projecting pin 60 projects from the board surface of the game board 30 by a predetermined length. On the other hand, the reinforcing rib 62a is set such that a recess (hole) deeper than the protruding length of the protruding pin 60 from the board surface is formed on the back side (the lower side in FIG. 9). Since the diameter of the protruding pin 60 is formed to be 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, the diameter of one game board 30 increases. The protruding protruding pins 60 are inserted into the recesses (holes) in the reinforcing ribs 62a from the back side of another game board 30. As a result, it is possible to prevent the game boards 30 stacked in a flat state from being displaced in the board surface direction.

  By forming the protruding pin 60 as a separate member from the game board 30 as in the present embodiment, the game board is formed until the protruding pin 60 is fitted into the opening 62 after the game board 30 is formed. The projecting pin 60 can be prevented from projecting from the board surface of the panel 30. This prevents the protruding pins 60 from hindering the transport of the game board 30 and from damaging the protruding pins 60 until the protruding pins 60 are fitted into the openings 62 after the game board 30 is formed. it can. Further, after the projecting pin 60 is fitted into the opening 62, if the projecting pin 60 becomes unnecessary when assembling the pachinko machine 1 or the like, the projecting pin 60 can be removed from the opening 62. This makes it possible to smoothly assemble the pachinko machine 1 and the like.

  Further, when the game board 30 is formed, the protruding pins can be formed integrally with the game board. When fitting (inserting) the protruding pin 60 to the game board 30 as in the present embodiment, it is necessary to prepare the protruding pin 60 as a separate member and insert the protruding pin 60 into the game board 30. On the other hand, by forming the projecting pin integrally with the game board, it is not necessary to prepare the projecting pin 60 as a separate member, so that the number of components can be reduced. Further, the operation of inserting the protruding pin 60 into the game board 30 can be omitted.

  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 synthetic resin into a molding die, and an outer peripheral edge reinforcing rib 73 is erected on the rear side of a flat board surface (front surface). When the game boards 30 made of synthetic resin are stacked and conveyed, there is a problem in that the position is shifted and the slide-down easily occurs as compared with the case where game boards made of wooden plywood are stacked and conveyed. This is because the game board 30 made of synthetic resin has higher surface smoothness and a smaller friction coefficient than the game board made of wooden plywood, so that it is easier to slide.

  On the other hand, according to the present embodiment, the game boards 30 are stacked by inserting the protruding pins 60 of one game board 30 into the recesses (holes) in the reinforcing ribs 62a of the other game boards 30. It can be easily transported. In addition, the fingertips of the hand can be easily inserted into the gap formed by the concave portion 73a formed on the end surface of the outer peripheral edge reinforcing rib 73, so that the gaming board 30 can be easily lifted. In addition, since the depressions 73a and 73c are formed at positions facing the outer peripheral edge reinforcing ribs 73, the fingertips of the hands and the like can be lifted in a well-balanced manner by inserting the fingertips of the hands into the depressions 73a and 73c from the left and right. Further, the concave portion 73b is formed on the outer peripheral edge reinforcing rib 73 (located on the lower side in FIG. 7) intersecting with the outer peripheral edge reinforcing rib 73 (located on the left and right in FIG. 7) in which the concave portions 73a and 73c are formed. The game board 30 can be supported from three sides of the game board 30, and the game board 30 can be transported in a well-balanced manner.

  Next, the guide portion reinforcing member 50 will be described with reference to FIGS. 11 is a partially enlarged front view of the game board 30 to which the guide portion (outer rail portion 31) and the guide portion reinforcing member 50 are fixed, FIG. 12 is a partially enlarged rear view thereof, and FIG. 13 is a guide portion reinforcing member 50. It is a perspective view of. The guide portion reinforcing member 50 is a member for preventing the outer rail portion 31 that the game ball fired from the game ball firing device 21 first collides with from swinging. Since the guide portion reinforcing member 50 is addressed to the outer rail portion 31, swing of the outer rail portion 31 is prevented. As a result, the trajectory of the game ball and the flight distance of the game ball to the game area PE can be stabilized.

  First, the outer rail portion 31 will be described with reference to FIG. The outer rail portion 31 is formed of a metal (stainless steel) band-shaped 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 31 is erected on the game board 30 by fitting the fitting pin 31 a into a hole 68 formed in the game board 30.

  Further, the outer rail portion 31 includes a bent portion 31b whose end in the longitudinal direction is bent and bent in a substantially U-shape. The bent portion 31b is a portion for preventing the edge of the outer rail portion 31 in the longitudinal direction from swinging, and guides the outer rail portion 31 through which a game ball fired from the game ball firing device 21 is guided. It is bent to the opposite side (back side) of the surface 31c. Thereby, when a game ball fired from the game ball launching device 21 collides with the guide surface 31c of the outer rail portion 31, the edge of the outer rail portion 31 tilts toward the opposite surface side (back surface 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. That is, the guide portion reinforcing member 50 is disposed between the fitting pins 31a. Since the fitting pins 31a are fixed to the outer rail 31 at appropriate intervals, the outer rail 31 easily swings between the fitting pins 31a. However, by arranging the guide portion reinforcing member 50 between the fitting pins 31a, it is possible to 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 (when viewed from the board side of the game board 30), and is opposite to the guide surface 31 c of the outer rail portion 31. The base portion 51 located on the surface side, the opposite-side projecting portion 52 erected on the base portion 51, and the base portion 51 in a direction opposite to the direction in which the opposite-side projecting portion 52 is erected. It mainly comprises a protruding fitting projection 55.

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

  The opposite surface side protruding portion 52 has an inclined portion 52a which is inclined downward from the top toward the base portion 51 side (board surface side), and is provided at least one at a position facing the outer rail portion 31 and connected to the inclined portion 52a. And a contact portion 52b with which the portion contacts. A fitting projection 55 is protruded from one side edge of the base portion 51 and the opposite surface side protruding portion 52. A rod-shaped columnar portion 53 is provided upright along the opposite surface side protruding portion 52 on the other side edge facing one side edge of the base portion 51 and the opposite surface side protruding portion 52. The columnar portion 53 is a portion for improving the bending rigidity of the opposite surface side protruding portion 52, is formed integrally with the base portion 51 and the opposite surface side protruding portion 52, and is located on the back side of the contact portion 52b. Accordingly, the protruding portion 52 on the side opposite to the axial direction of the columnar portion 53 can be hardly bent and deformed as compared with the case where the columnar portion 53 is not formed.

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

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

  The length of one side edge of the base portion 51 at which the fitting projection 55 protrudes is set shorter than the length of the other side edge facing the one side edge. Since the other side edge of the base portion 51 is continuously provided on the bottom side of the columnar portion 53 and the reinforcing portion 54, the bottom area of the base portion 51 gradually increases from one side edge of the base portion 51 to the other side edge. It is set to be. By making the bottom area of the base part 51 located far from the fitting projection 55 larger than the bottom area of the base part 51 located near the fitting projection 55, the bottom part located far from the fitting projection 55 is formed. Area shortage can be prevented. As a result, the swing of the opposite-side projecting portion 52 at a position far from the fitting projection 55 can be suppressed.

  Since the guide portion reinforcing member 50 includes the base portion 51 disposed along the outer rail portion 31, as shown in FIG. Can be shifted to the end (bent portion 31b) side of the outer rail portion 31. As a result, the position of the fitting pin 31a for fixing the outer rail portion 31 to the game board 30 can be made closer to the position of the opposite surface side protruding portion 52 (contact portion 52b). By bringing the contact portion 52b closer to the fitting pin 31a for fixing the outer rail portion 31, the outer rail portion 31 can be hardly bent between the fitting pin 31a and the contact portion 52b. As a result, the outer rail portion 31 can be effectively reinforced by the guide portion reinforcing member 50.

  The fitting projection 55 is a portion that is fitted into a hole 69 formed in the game board 30 in order to fix the guide portion reinforcing member 50 to the game board 30. In the present embodiment, the fitting projection 55 is substantially circular. It is formed in a column 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 set so that the area of the cross section orthogonal to the axis gradually decreases toward the distal end side. Since the reduced diameter portion 55a is formed, the fitting projection 55 can be easily inserted into the hole 69. Further, since the fitting projection 55 and the hole 69 are formed in a substantially circular cross section, it is possible to omit a fine position adjustment when the guide portion reinforcing member 50 is inserted into the hole 69. As a result, the workability of inserting the guide portion reinforcing member 50 into the hole 69 can be improved.

  With reference to FIG. 12, the fitting projection 55 will be described. FIG. 12 is a partially enlarged rear view of the game board 30 provided with the guide portion (outer rail portion 31) and the guide portion reinforcing member 50. In FIG. 12, the position of the outer rail portion 31 arranged on the board surface of the game board 30 is shown by an imaginary line (two-dot chain line).

  As shown in FIG. 12, the fitting projection 55 includes a concave portion 56 in which a part of the outer peripheral surface is formed in a concave shape. Since the concave portion 56 forms a part of the outer peripheral surface of the fitting convex portion 55 in a concave shape, when the fitting convex portion 55 is fitted into the hole portion 69, the outer peripheral surface of the fitting convex portion 55 and the hole portion 69 are formed. Can be reduced in contact area with the inner peripheral surface. As a result, the vertical effectiveness per unit area of the hole 69 and the fitting protrusion 55 when the fitting protrusion 55 is fitted into the hole 69 can be increased. Thereby, when the fitting protrusion 55 is fitted into the hole 69, the hole 69 or the fitting protrusion 55 can be easily deformed (elastic deformation or plastic deformation). 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 base end. As a result, the fitting protrusion 55 can be fitted into the hole 69 by utilizing the elastic deformation of the fitting protrusion 55 due to the sliding. Thereby, the fitting projection 55 can be easily fitted into the hole 69. Further, by utilizing the elastic deformation of the fitting projection 55, it is possible to prevent a gap from being formed between the hole 69 and the fitting projection 55. As a result, the fitting projection 55 fitted into the hole 69 can be made less likely to rattle.

  Further, in the present embodiment, the sliding direction of the concave portion 56 as viewed from the axial direction of the fitting convex portion 55 (the direction perpendicular to the plane of FIG. 12) is non-parallel to the longitudinal direction of the outer rail portion 31. Thereby, when the guide surface 31c is pushed to the opposite surface side (the lower side in FIG. 12) by the game ball proceeding toward the game area PE along the guide surface 31c of the belt-shaped outer rail portion 31, the fitting projection is formed. The portion 55 can be hardly elastically deformed. Thereby, the guide portion reinforcing member 50 can be hardly tilted.

  That is, the fitting projection 55 is hardly elastically deformed by a load parallel to the sliding direction, and is easily elastically deformed by a load perpendicular to the sliding direction. This is because when a load parallel to the sliding direction is applied to the fitting protrusion 55, the fitting protrusion 55 is deformed so as to reduce the gap between the slit-shaped recesses 56. Therefore, if the guide portion reinforcing member 50 is arranged so that the sliding direction of the fitting convex portion 55 is parallel to the longitudinal direction of the outer rail portion 31, the guide surface 31c of the outer rail portion 31 is pushed to the opposite surface side. When this is done, the outer rail portion 31 tends to tilt due to the elastic deformation of the fitting projection 55. On the other hand, if the guide portion reinforcing member 50 is arranged so that the sliding direction of the fitting convex portion 55 is not parallel to the longitudinal direction of the outer rail portion 31, the guide surface 31c of the outer rail portion 31 becomes the opposite surface. When pushed to the side, the fitting projection 55 can be made less likely to be elastically deformed. Thereby, the guide portion reinforcing member 50 can be hardly tilted.

  In particular, by making the longitudinal direction of the outer rail portion 31 perpendicular to the sliding direction of the concave portion 56, the fitting convex portion 55 can be made most difficult to be elastically deformed by a load parallel to the sliding direction. Accordingly, it is possible to suppress the guide portion reinforcing member 50 from tilting together with the tilting of the outer rail portion 31. As a result, it is possible to suppress the outer rail portion 31 from tilting with the progress of the game ball, and to stabilize the trajectory and flight distance of the game ball traveling along the outer rail portion 31.

  Note that by making the longitudinal direction of the outer rail portion 31 and the sliding direction of the concave portion 56 non-perpendicular, it is possible to use the elastic deformation of the fitting convex portion 55 by a load parallel to the sliding direction. is there. In particular, by making the longitudinal direction of the outer rail portion 31 parallel to the sliding direction of the concave portion 56, the elastic deformation of the fitting convex portion 55 can be used most actively. As the outer rail portion 31 tilts due to the progress of the game ball, the guide portion reinforcing member 50 (the opposite protruding portion 52) is tilted together to elastically deform the fitting convex portion 55, and the fitting convex portion 55 By the restoring force, it is possible to restore the guide portion reinforcing member 50 (the opposite protruding portion 52) and the outer rail portion 31 to their original positions. By utilizing the elastic deformation of the fitting projection 55, it is possible to prevent the guide portion reinforcing member 50 from being damaged by a load (a load by a game ball) 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 to stabilize the trajectory and flight distance of the game ball traveling along the outer rail portion 31.

  In addition, the fitting protrusion 55 has a concave notch 56a having a substantially circular cross-section and connected to the recess 56 along the axis (perpendicular to FIG. 12) substantially at the center of the fitting protrusion 55. ing. Since the concave notch 56a is formed, the cross-sectional area of substantially the center (near the axis) of the fitting projection 55 can be reduced. Thereby, the cross-sectional shape of the fitting protrusion 55 on both sides of the recess 56 in the axial direction can be made substantially fan-shaped. As a result, when a load parallel to the sliding direction is applied to the fitting protrusion 55, the fitting protrusion 55 can be deformed so as to reduce the cross-sectional area of the recess 56a. Thus, the fitting protrusion 55 can be fitted into the hole 69 by utilizing the elastic deformation of the fitting protrusion 55 caused by the concave notch 56a. Thereby, the fitting projection 55 can be easily fitted into the hole 69.

  Since the amount of elastic deformation of the fitting protrusion 55 due to the recess 56a is smaller than the amount of elastic deformation of the fitting protrusion 55 due to the recess 56, the fitting protrusion in the sliding direction (substantially the vertical direction in FIG. 12). The amount of elastic deformation of the fitting projection 55 in the direction orthogonal to the sliding (the substantially right-left direction in FIG. 12) can be made different from the amount of elastic deformation of the fitting 55. Specifically, the amount of elastic deformation of the fitting protrusion 55 in the sliding direction (substantially up and down direction in FIG. 12) is determined by changing the amount of elastic deformation of the fitting protrusion 55 in a direction perpendicular to the sliding (substantially left and right direction in FIG. 12). Can be smaller than quantity. Therefore, it is possible to prevent the effect that the guide portion reinforcing member 50 is hardly tilted from being impaired when the concave portion 56a is formed.

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

  Returning to FIG. 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 protrusion portion 52, and is provided on the guide surface side protrusion contacting the guide surface 31c. A portion 57 is provided. As shown in FIGS. 11 and 13, the guide surface side protruding portion 57 is protruded from a part of the fitting convex portion 55 in the axial direction on the base end side (the near side in FIG. 11). A groove 58 into which the outer rail 31 is inserted is formed between the guide surface side projecting portion 57 and the opposite surface side projecting portion 52.

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

  Since the guide portion reinforcing member 50 includes the guide surface side projecting portion 57, the outer rail portion 31 is held in the groove 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 protruding portion 52 and the guide surface side protruding portion 57 of the guide portion reinforcing member 50, the tilting of the outer rail portion 31 can be reliably prevented.

  Further, since the guide surface side protruding portion 57 provided on the guide surface 31c side of the outer rail portion 31 is set lower than the height of the opposite surface side protruding portion 52, the game ball B along the guide surface 31c is provided. Can be prevented from being obstructed by the guide surface side protruding portion 57. When the game ball B interferes with the guide surface side projecting portion 57, the kinetic energy of the game ball B is lost, and the flight distance of the game ball B guided to the game area PE becomes unstable, but this can be prevented. 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 slit shape from the distal end (the lower side in FIG. 14) of the fitting convex portion 55 except for the base end (the proximal end portion 55b) of the solid fitting convex portion 55. Is formed. Thereby, the base end portion 55b of the solid fitting projection 55 can be fitted into the hole 69 (board side). By fitting the base end 55b of the solid fitting projection 55 into the hole 69 (board side), it is possible to prevent the fitting projection 55 from rattling with the hole 69. Further, since the concave portion 56 is formed on the tip end side of the fitting convex portion 55, the fitting convex portion 55 or the hole 69 can be easily elastically or plastically deformed. 69 can be easily fitted.

  The gap between the outer peripheral surface of the fitting convex portion 55 (the base end portion 55b) and the hole portion 69 is formed by the groove 58 between the opposite surface side protruding portion 52 and the guide surface side protruding portion 57. It is set to a value smaller than the gap between the rail portion 31 and the projecting portion 52 on the opposite surface side or the projecting portion 57 on the guide surface side. While the fitting projection 55 (base end 55b) fitted in the hole 69 is prevented from rattling, when the outer rail portion 31 is fixed to the game board 30, the opposite surface side projecting portion 52 and the guide are provided. This is for facilitating the insertion of the outer rail portion 31 into the groove portion 58 between the surface side projecting portions 57. In addition, even if a gap is formed between the opposite surface side protruding portion 52 or the guide surface side protruding portion 57 and the outer rail portion 31, the outer rail portion 31 is fixed to the game board 30 by the fitting pin 31a. The play 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 that regulates the tilting of the outer rail portion 31 includes the fitting protrusion 55 that fits into the hole 69 formed in the recessed surface of the game board 30, and the fitting protrusion 55. A protruding portion 52 that protrudes from the portion 55 and contacts the opposite surface of the outer rail portion 31 from the guide surface 31c. The guide portion reinforcing member 50 is formed on the opposite surface side protruding portion in which the fitting convex 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 fitting convex portion 55 is provided. 52 contacts the opposite side of the guide surface 31c of the outer rail portion 31. Accordingly, it is possible to prevent the guide surface 31c from being pushed to the opposite surface side and the belt-shaped outer rail portion 31 from tilting outward due to a game ball traveling toward the game area PE along the guide surface 31c. Since the 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 proceeding 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 changes or the game ball changes. Or a 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, the guide surface reinforcing member 50 is arranged such that the opposite surface side protruding portion 52 is in contact with the opposite surface of the outer rail portion 31 from the guide surface 31c, so that the guide surface is provided. It is possible to suppress the outer rail portion 31 from tilting due to a game ball traveling toward the game area PE along 31c. Thereby, the trajectory and flight distance of the game ball guided to the game area PE can be stabilized.

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

  Further, since the concave portion 56 is formed in a slit shape from the distal end of the fitting convex portion 55 toward the base end (the base end portion 55b), the elastic deformation of the fitting convex portion 55 due to the sliding is utilized. The fitting projection 55 can be fitted into the hole 69. As a result, the fitting projection 55 can be easily fitted into the hole 69, and a gap is prevented from being formed between the hole 69 and the fitting projection 55 by utilizing the elastic deformation of the fitting projection 55. Since it is possible, the fitting protrusion 55 fitted into the hole 69 can be made less likely to rattle.

  In addition, since the direction of the sliding of the concave portion 56 as viewed from the axial direction of the fitting convex portion 55 is arranged non-parallel to the longitudinal direction of the outer rail portion 31, along the guide surface 31 c of the strip-shaped outer rail portion 31. When the guide surface 31c is pushed to the opposite side by the game ball which advances toward the game area PE, the fitting convex portion 55 can be hardly elastically deformed. Thereby, it can suppress that the outer rail part 31 inclines. As a result, the trajectory and flight distance of the game balls 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. Thereby, the tilting of the outer rail portion 31 can be reliably prevented. As a result, the trajectory and flight distance of the game balls guided to the game area PE can be further stabilized. Further, since the guide surface side projecting portion 57 is set lower than the height of 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. it can.

  Also, the opposite surface side protruding portion 52 is provided with an inclined portion 52 a which is inclined downward from the top toward the outside in the axial direction of the fitting convex portion 55, and is provided continuously with the inclined portion 52 a and opposite to the outer rail portion 31. 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 and the outer rail portion 31 can be easily arranged on the board surface of the game board 30.

  That is, when arranging the guide portion reinforcing member 50 and the outer rail portion 31 on the board surface of the game board 30, first, about half the length of the fitting convex portion 55 of the guide portion reinforcing member 50 is reduced. Insert into the hole 69. Since the fitting projection 55 has a slot-shaped recess 56, when the slot is inserted into the hole 69 of the game board 30, the fitting projection 55 is formed so as to reduce the interval between the slot-shaped recesses 56. Deform. Therefore, the work of inserting about half the length of the fitting projection 55 into the hole 69 of the game board 30 can be facilitated.

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

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

  Since the base end 55b of the fitting projection 55 is formed in a solid shape, the base end 55b is fitted into the hole 69. Thereby, it is possible to prevent the fitting protrusion 55 from rattling in the hole 69.

  Further, the projection 69a is protruded toward the rear side from the thin portion 72 of the game board 30, and the hole 69 is formed through the projection 69a and the thin portion 72 so that the projection 69a is fitted into the hole 69. The fitting depth of the fitting projection 55 can be secured. 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 a direction orthogonal to the axial direction. Since the fitting depth of the fitting projection 55 fitted into the hole 69 is ensured, the guide portion reinforcing member 50 fixed to the game board 30 can be made difficult to swing. By making the guide portion reinforcing member 50 fixed to the game board 30 difficult to swing, the tilting of the outer rail portion 31 that guides the game ball to the game area PE can be suppressed, so that the game ball guided to the game area PE Orbit and flight distance can be further stabilized.

  Further, since the projecting portion 69a is coupled to the thin portion 72 and the hole 69 is formed through the projecting portion 69a and the thin portion 72, it is necessary to increase the area of the thick portion 70 in order to form the hole 69. Can be unnecessary. Although the mass of the game board 30 is increased by the protrusion 69 a (excluding the hole 69) coupled to the thin portion 72, it is not necessary to increase the area of the thick portion 70. The increase can be suppressed. Further, the projection 69 a formed with the hole 69 therethrough functions as a rib for increasing the rigidity of the thin portion 72 around the hole 69, so that the rigidity of the thin portion 72 around the hole 69 can be secured. Therefore, a nail can be implanted in the thick portion 70 to secure the holding force of the nail, and the game board 30 can be reduced in weight while securing the rigidity of the game board 30. In addition, the trajectory and flight distance of the game ball guided to the game area PE can be further stabilized.

  Next, a guide portion reinforcing member 50 according to another embodiment will be described with reference to FIG. The same parts as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. FIG. 15A is a partially enlarged rear view of a game board 30 provided with a guide portion reinforcing member 80 according to another embodiment, and FIG. 15B is a game provided with a guide portion reinforcing member 90 according to another embodiment. It is a partial enlarged rear view of the board 30. 15 (a) and 15 (b), fitting protrusions 85, 95 of guide portion reinforcing members 80, 90 are fitted into holes 69 formed in game board 30 from the board surface (front) side. Then, a state viewed from the back side of the game board 30 is illustrated.

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

  A concave notch 85 a having a circular cross section is formed substantially at the center of the fitting protrusion 85 along the axial direction of the fitting protrusion 85 from the tip of the fitting protrusion 85. By reducing the cross-sectional area of the fitting projection 85 by the concave notch 85a, the fitting projection 85 can be easily elastically deformed by the vertical force acting on the fitting projection 85. Thereby, the fitting protrusion 85 can be more easily fitted into the hole 69, so that the workability when fitting the fitting protrusion 85 into the hole 69 can be improved. Further, by making the fitting projection 85 easily elastically deform, it is possible to prevent the fitting projection 85 from rattling with the hole 69.

  In particular, since the concave portion 86 is formed in such a shape that two portions are cut out along the axial direction of the fitting convex portion 85, the outer peripheral surface of the fitting convex portion 85 is prevented from being excessively small, A contact area with the inner peripheral surface of the hole 69 can be secured. Since the vertical effect per unit area of the outer peripheral surface of the fitting convex portion 85 can be prevented from being excessive, deformation such as buckling of the outer peripheral surface of the fitting convex portion 85 can be suppressed. Thereby, it is possible to suppress a problem that a gap is formed between the outer peripheral surface of the fitting convex portion 85 and the inner peripheral surface of the hole portion 69, and the fitting convex portion 85 is loose.

  The guide portion reinforcing member 90 shown in FIG. 15B has a portion of the outer peripheral surface at four axially symmetrical positions on the outer peripheral surface of the fitting projection 95 along the axial direction (perpendicular to the paper surface of FIG. 15B). Is provided with a concave portion 96 formed in a concave shape. Since the fitting protrusion 95 has the concave portion 96 in which a part of the outer peripheral surface is formed in a concave shape, the outer peripheral surface of the fitting protrusion 95 when the fitting protrusion 95 is fitted into the hole 69. The contact area between the hole and the inner peripheral surface of the hole 69 can be reduced. As a result, the vertical effectiveness per unit area of the hole 69 and the fitting protrusion 95 when the fitting protrusion 95 is fitted into the hole 69 can be increased. Thereby, when the fitting projection 95 is fitted into the hole 69, the hole 69 or the fitting projection 95 can be easily deformed (elastic deformation or plastic deformation). It can be easily fitted into the hole 69.

  At the approximate center of the fitting projection 95, a concave notch 95a having a circular cross section is formed 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 by the concave notch 95a, the fitting projection 95 can be easily elastically deformed by the vertical effect acting on the fitting projection 95. Thereby, the fitting projection 95 can be more easily fitted into the hole 69, so that the workability when fitting the fitting projection 95 into the hole 69 can be improved. Furthermore, by making the fitting projection 95 easily elastically deform, it is possible to prevent the fitting projection 95 from rattling with the hole 69.

  Next, a second embodiment will be described with reference to FIG. In the first embodiment, the outer peripheral edge of the opening 61 penetratingly formed in the thickness direction of the game board 30 is continuous inside the outer peripheral edge of the game board 30 (the outer peripheral edge of the game board 30 is closed). The case has been described. On the other hand, in the second embodiment, a case will be described in which the opening 161 is formed to penetrate in the thickness direction of the game board 130 and a part of the outer peripheral edge of the game board 130 is opened. The same parts as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. FIG. 16 is a front view of a game board 130 and a structure 170 which are 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 so as to penetrate in the thickness direction of the game board 130 (perpendicular to the paper surface of FIG. 16) and partially opening the outer peripheral edge of the game board 130. And a structure 170 for connecting the peripheral edges of the opening 161 to each other. In the present embodiment, a part of the outer peripheral edge of the game board 130 located on the right side when viewed from the front is opened by the opening 161. By forming the opening 161, the 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 of the periphery of the opening 161 of the game board 130. In the present embodiment, the structure 170 is formed in a substantially rectangular shape when viewed from the front, and connects two portions of the opening 161 along the outer peripheral edge of the game board 130. The game board 130 and the structure 170 are formed of a light-transmitting synthetic resin, similarly to the game board 30 described in the first embodiment. A symbol display device 43a (see FIG. 5) is arranged inside the opening 161 in which a part of the outer peripheral edge is closed by the structure 170, as in the first embodiment.

  Next, a connection structure between the game board 130 and the structure 170 will be described with reference to FIG. FIG. 17 is a perspective view of the game board 130 and the structure 170. 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 has a main body 172 formed in a substantially rectangular parallelepiped box shape, and protrudes from the front side of the main body 172 on both sides up and down (in a direction substantially parallel to the board surface of the game board 30). It mainly comprises an engagement portion 171 formed in a flange shape.

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

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

  In the game board 130, a connecting portion (engaged portion) 131 that receives the engaging portion 171 provided on the structure 170 is formed at a part of the periphery of the opening 161. The connection part 131 is a part for positioning the structure 170 by engaging with the engagement part 171 provided on the structure 170.

  In the present embodiment, the connecting portion 131 is provided as a step-shaped flat surface that is 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 gaming board 130 (in the left-right direction in FIG. 17) is set substantially equal to the thickness of the engaging portion 171 (in the left-right direction in FIG. 17).

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

  The connecting portion 131 is formed with an insertion hole 133 through which an insertion hole 174 formed in the structure 170 (engaging portion 171) is connected in the axial direction, into which a shaft 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 by a shaft-like member such as a screw that is screwed into the insertion holes 133 and 174.

  Next, the light scattering section 132 will be described with reference to FIG. The light scattering portion 132 is formed on the rear side of the connecting portion 131 as a ridge or a projecting portion. A support 180 is provided 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.

  The light (indicated by a two-dot chain line in FIG. 18) emitted from the light emitting portion 181 enters and exits the light scattering portion 132 (the engaged portion 131) due to the difference in refractive index between the air and the light scattering portion 132. Sometimes refracted. Therefore, if the light emitting section 181 emits light, it is possible to realize an electric decoration in a state where a large number of lights are dispersed or a state with a three-dimensional effect. Thereby, in addition to the effect produced by the symbol display unit 173 (decorative portion), the effect produced by the light from the light emitting unit 181 can be improved.

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

  Also, when the light scattering portion 132 is provided by processing the board surface (surface) of the game board 130 into a ridge or projection, the unevenness of the light scattering portion 132 interferes with the movement of the game ball, In the case where the light scattering portion 132 is provided on the back surface (back surface) of the game board 130, it is not necessary to consider the interference of the movement of the game ball by the light scattering portion 132 (unevenness). Thereby, the flexibility of the design of the game board 130 can be ensured.

  When the light scattering portion 132 is provided on the back side (back surface) of the game board 130 (the connecting portion 131), the shape of the light scattering portion 132 can be designed relatively freely. The outer peripheral edge of the gaming board 130 is provided with an outer peripheral reinforcing rib 73 (see FIG. 17) standing up toward the rear side. This is because space can be secured.

  In addition, the light scattering part 132 scatters light, so that a shadow of a shaft-like member (not shown) such as a screw inserted into the insertion holes 133 and 174 is cast from the board surface of the game board 130 and the front face of the structure 170. It can be prevented from being visually recognized. This is because the light can be scattered in front of the shaft member (not shown) by scattering the light by the light scattering section 132. This makes it difficult to visually recognize the joint (the connecting portion 131 and the engaging portion 171) between the game board 130 and the structure 170 due to the light scattered by the light scattering section 132, and also allows the game board 130 and the structure 170 The staging effect can be improved.

  According to the pachinko machine 1 configured as described above, the opening 161 penetratingly formed in the thickness direction of the game board 130 has a part of the outer peripheral edge of the game board 130 opened, and the peripheral edge of the opening 161 has two edges. The points are connected by the structure 170. Thereby, the structure 170 can be made three-dimensional using a space in the thickness direction of the game board 130. Since the structure 170 includes the symbol display portion 173 (decorative portion), a three-dimensional effect using a space in the thickness direction of the game board 130 can be implemented. Thereby, the interest of the game can be greatly enhanced.

  Here, in a conventional structure in which components such as a display device and an accessory are attached to the surface of a game board, since the spread in the depth direction is poor, similar effects are easily adopted, and it is difficult to enhance the interest of the game. Also, in the conventional game board made of wooden plywood (veneer), in consideration of the workability and mechanical strength of the wooden plywood, a structure in which an opening for opening a part of the outer peripheral edge of the game board is adopted. hard.

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

  A game ball launching device for launching a game ball, a game board made of synthetic resin forming a game area in which a game ball fired by the game ball launching device flows down, and the game ball launching device arranged on the board of the game board And a belt-shaped guide portion for guiding a game ball fired by the device to the game area along a guide surface, comprising a guide portion reinforcing member fixed to the board surface of the game board, and reinforcing the guide portion. The member has a fitting protrusion fitted into a recess formed in the board surface of the game board, and a member protruding from the fitting protrusion and contacting the opposite side of the guide surface of the guide portion. A gaming machine A1 comprising: a protruding portion on the opposite side.

  According to the gaming machine A1, a game area in which a game ball fired by the game ball firing device flows is formed by a game board made of synthetic resin. On the board of the game board, a belt-like guide portion for guiding a game ball fired by the game ball launching device to a game area along a guide surface is arranged. A guide reinforcing member is fixed to the board surface of the game board. The guide portion reinforcing member is configured such that a fitting protrusion fits into a hole formed in a recessed shape on the board surface of the game board, and a projecting portion on the opposite surface protrudingly provided in the fitting protrusion guides the guide portion. Contact the opposite side of the surface. Accordingly, it is possible to suppress the tilting of the belt-shaped guide portion due to the guide surface being pushed to the opposite surface side by the game ball proceeding toward the game area along the guide surface. Since the tilting of the guide portion for guiding 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 surface side by the game ball traveling toward the game area along the guide surface and the belt-shaped guide portion tilts, the trajectory of the game ball changes or the kinetic energy of the game ball is lost. May occur. As a result, the trajectory and flight distance of the game ball guided to the game area may become unstable.

  On the other hand, according to the gaming machine A1, by arranging the guide portion reinforcing member so that the opposite surface side protruding portion contacts the opposite surface of the guide surface of the guide portion, the game area is extended along the guide surface. It is possible to suppress the guide portion from tilting due to the game ball traveling toward. Thereby, the trajectory and flight distance of the game ball guided to the game area can be stabilized.

  The gaming machine A2 according to the gaming machine A1, wherein the fitting projection has a concave portion in which a part of an outer peripheral surface is formed in a concave shape.

  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 when the fitting convex portion is fitted into the hole portion is formed. The contact area with the inner peripheral surface of the hole can be reduced. As a result, it is possible to increase the vertical effectiveness per unit area of the hole and the fitting protrusion when the fitting protrusion is fitted into the hole. This makes it easy to deform (elastic deformation or plastic deformation) the hole or the fitting protrusion when the fitting protrusion is fitted to the hole. There is an effect that the mating projection can be easily fitted into the hole.

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

  According to the gaming machine A3, since the concave portion is formed in a sliding manner from the distal end to the base end of the fitting convex portion, the fitting portion is fitted into the hole portion by utilizing the elastic deformation of the fitting convex portion due to the sliding. The mating projections can be fitted. As a result, in addition to the effect of the gaming machine A1 or A2, the fitting protrusion can be easily fitted into the hole, and the hole and the fitting protrusion can be formed by utilizing the elastic deformation of the fitting protrusion. Since the formation of the gap can be prevented, there is an effect that the fitting protrusion fitted in the hole can be made less likely to rattle.

  In the gaming machine A3, the guide portion reinforcing member may be arranged such that a direction of the groove of the concave portion viewed from an axial direction of the fitting convex portion is not parallel to a longitudinal direction of the guide portion. Gaming machine A4.

  According to the gaming machine A4, since the guide portion reinforcing member is arranged in such a manner that the sliding direction of the concave portion viewed from the axial direction of the fitting convex portion is not parallel to the longitudinal direction of the guide portion, the guide of the belt-shaped guide portion is provided. When the guide surface is pushed to the opposite surface side by a game ball which advances toward the game area along the surface, the fitting convex portion can be hardly elastically deformed. Thereby, it can suppress that a guide part tilts. As a result, in addition to the effect played by the gaming machine A3, there is an effect that the trajectory and flight distance of the game ball guided to the game area can be further stabilized.

  That is, the fitting convex portion is not easily elastically deformed by a load parallel to the sliding direction, and is easily elastically deformed by a load orthogonal to the sliding direction. Therefore, if the guide portion reinforcing member is arranged so that the sliding direction of the fitting protrusion is parallel to the longitudinal direction of the guide portion, when the guide surface of the guide portion is pushed to the opposite surface side, the fitting protrusion is formed. The guide portion is easily tilted by the elastic deformation of the portion. On the other hand, if the guide portion reinforcing member is arranged so that the sliding direction 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 surface side, The fitting projection can be made less likely to be elastically deformed. This makes it difficult to tilt the guide portion toward the opposite surface side of the guide surface.

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

  According to the gaming machine A5, the guide surface side protrusion provided on the guide surface side of the guide portion facing the opposite surface protrusion portion comes into contact with the guide surface of the guide portion. The guide portion is held between the portion and the guide surface side protruding portion. Since the guide portion is held from both the guide surface and the opposite surface by the guide portion reinforcing member, the tilting of the guide portion can be reliably prevented in addition to the effect of any of the gaming machines A1 to A4. As a result, there is an effect that the trajectory and flight distance of the game ball guided to the game area can be further stabilized.

  Also, since the guide surface side protruding portion provided on the guide surface side of the guide portion is set lower than the height of the opposite surface side protruding portion, the progress of the game ball along the guide surface is guided by the guide surface side protruding portion. The installation can be prevented from interfering. When the game ball interferes with the guide surface side protruding portion, the kinetic energy of the game ball is lost and the flight distance of the game ball guided to the game area becomes unstable. This can be prevented, so the guide to the game area can be prevented. It is possible to prevent the flying distance of the played game ball from becoming unstable.

  In any one of the gaming machines A1 to A5, the opposite surface-side protruding portion is provided with an inclined portion inclined downward from the top toward the fitting convex portion side, and is connected to the inclined portion and the guide portion is provided. A gaming machine A6 comprising: a contact portion facing at least a part of the opposite surface while facing the opposite surface.

  According to the gaming machine A6, when the guide portion reinforcing member and the guide portion are arranged on the board surface of the game board, first, the fitting convex portion of the guide portion reinforcing member is inserted into the hole of the game board. Next, the guide portion is arranged along the inclined portion of the protruding portion on the opposite surface side such that the opposite surface faces the contact portion of the guide portion reinforcing member. The inclined portion is inclined downward from the top toward the fitting convex portion, and the contact portion is provided continuously with the inclined portion, so that the guide portion can be smoothly arranged along the inclined portion to the contact portion. it can. Thus, in addition to the effect of any one of the game boards A1 to A5, the guide portion can be smoothly arranged on the board surface of the game board, and the effect of improving the workability of arranging the guide portion on the board surface can be improved. is there.

  In any one of the gaming machines A1 to A6, the gaming board is located on the back side of the gaming area, and a nail is implanted on the board surface. A thin portion having a thickness smaller than that of the thin portion, an outer peripheral edge reinforcing rib erected from the outer peripheral edge of the thin portion to the rear side, and a projection formed by projecting rearward from a predetermined portion of the thin portion. A gaming machine A7, characterized in that the gaming machine A7 includes a hole, and the hole is formed through the thin portion and the protruding portion.

  According to the gaming machine A7, since the nails are implanted on the wall of the thick portion located on the back side of the game area in the gaming machine A7, the nail holding force can be secured by securing the nail driving depth. In addition, since a thin portion having a thickness smaller than that of the thick portion is connected to the thick portion, a game board having no thin portion (game board formed uniformly with the thickness of the thick portion) The game board can be reduced in weight as compared with. Further, since the outer peripheral edge reinforcing ribs are provided upright 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, the game board can be reduced in weight while securing rigidity, and the holding power of nails implanted on the board surface can be increased.

  In addition, since the protruding portion is connected to the thin portion and protrudes from the predetermined portion to the back side, and the hole is formed through the thin portion and the protruding portion, the fitting of the fitting protrusion fitted into the hole is performed. The depth can be secured. As the fitting depth of the fitting projection fitted into the hole increases, the fitting projection fitted into the hole tends to be less likely to swing in a direction orthogonal to the axial direction. By ensuring the fitting depth of the fitting projection fitted into the hole, the guide portion reinforcing member fixed to the game board can be made difficult to swing. By making it difficult for the guide portion reinforcing member fixed to the game board to swing, the tilt of the guide portion for guiding the game ball to the game area can be suppressed, so that the trajectory and flight distance of the game ball guided to the game area can be reduced. Further stabilization is possible.

  In addition, since the projecting portion is formed by projecting from the predetermined portion of the thin portion to the back side and connecting the projecting portion, and the hole is formed through the projecting portion and the thin portion, the area of the thick portion is increased to form the hole. Can be eliminated. The mass of the game board increases by the protruding portion (excluding the hole) coupled to the thin portion, but 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 protrusion having the hole formed therethrough exhibits a rib function of increasing the rigidity of the thin portion around the hole, the rigidity of the thin portion around the hole can be secured.

  As described above, according to the gaming machine A7, in addition to the effect of any one of the gaming machines A1 to A6, the game board can be reduced in weight while securing the rigidity of the game board, and the holding of nails implanted on the board surface can be achieved. In addition to being able to increase the power, there is an effect that the trajectory and flight distance of the game ball guided to the game area can be further stabilized.

Gaming machine B1.

  According to the gaming machine B1, a game area in which a game ball flows down is formed by a game board made of synthetic resin, and an opening is formed through the game board in a thickness direction thereof. In the opening, a part of the outer peripheral edge of the game board is opened, and in the opening, a structure as a member that interferes with the movement of the game ball, a member through which the game ball passes, or a member used for announcement or production of a game. Be placed. As a result, the structure can be arranged less likely to be restricted by the game board. As a result, there is an effect that the degree of freedom of the game effect can be improved, and the interest of the game can be greatly enhanced.

  That is, conventionally, as this type of gaming machine, a pachinko machine in which a game ball is fired at a game area and a predetermined number of game balls are paid out when a game ball is won at various winning ports in the game area. is there. In a pachinko machine, for example, a symbol display unit such as a liquid crystal display device is arranged at the center of the game area, and symbols in a plurality of rows are variably displayed by the symbol change unit. The symbol display by the symbol display unit is started by the winning of the predetermined winning opening (start winning opening) as a trigger, and thereafter, the variable display of the symbol is stopped via the variable display by the predetermined variation pattern.
