Description

  The present invention relates to a gaming machine represented by a pachinko machine or the like.

  There is a pachinko machine as a typical example of a gaming machine that uses a game ball to play a game. The pachinko machine has a game board in which a game area is formed on the front surface. In the game area, there is a entrance part where a game ball can enter, and if the entrance into the entrance part occurs, for example, whether or not to generate a special game state advantageous to the player Benefits such as a lottery and game ball payout are given to the player.

  In this type of gaming machine, a conventional gaming board is generally one in which a synthetic resin film on which a pattern is printed is attached to the surface of a wooden plywood (veneer). In recent years, a game board made of synthetic resin is being adopted from the viewpoint of designability and recyclability (for example, Patent Document 1).

  In such a pachinko machine, a game board is generally detachably attached to the pachinko machine body so that the game board can be exchanged for the pachinko machine body as necessary, such as changing the model. Therefore, generally, the game board is produced through a manufacturing process separate from the pachinko machine body. In the manufacturing process of the synthetic resin game board, first, nails (obstacles) are planted on the board material for the synthetic resin game board. Then, after attaching small parts, such as a windmill, and a rail member (guidance rail) to a board material, large parts, such as a large prize-winning device and a control circuit board, are assembled. Assembling large parts complicates the work, so the process capability decreases. Due to the imbalance of the process capability, a game board that is being manufactured may stay temporarily between processes. In such a case, in order to make the staying game board stand by, the game board in the middle of manufacture may be temporarily stacked.

  Next, a cross-sectional shape of the game board 30 will be described with reference to FIG. FIG. 8 is a cut 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 as a flat surface on the board side (front side, lower side in FIG. 8), and the thick portion 70 is formed on the rear side (upper side in FIG. 8) and has a plate thickness. It is set almost constant. The inclined surface portion 71 is connected to the thick portion 70 and is formed such that the plate thickness gradually decreases as it approaches the peripheral edge of the game board 30 (towards 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 part 72, and is provided continuously around the thin part 72 and protrudes from the outer peripheral edge of the thin part 72 to the back side. Since the height of the outer peripheral reinforcing rib 73 (vertical direction in FIG. 8) is set to a value larger than the thickness of the thick portion 70, the outer peripheral reinforcing rib 73 is externally attached to the resin base 20 of the main body frame 3. It is possible to prevent the thick portion 70 from interfering with the resin base 20 when the rear end portion of the peripheral reinforcing rib 73 is brought into contact with the front surface of 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 the game ball is planted in the game area PE, a thick portion 70 is formed at a substantially central portion of the game board 30 on which the game area PE is formed to ensure the thickness. The holding power of the nail implanted in the part 70 can be ensured.

  Further, in the game board 30, the thickness of the thick portion 70 is set to be smaller than the height of the outer peripheral edge reinforcing rib 73, so that the game has a uniform thickness in which the height of the outer peripheral edge reinforcing rib 73 is the plate thickness. The weight can be reduced compared to the board. Since a space can be provided on the back side of the thick portion 70 by the amount that the thickness of the thick portion 70 is set to be smaller than the height of the outer peripheral reinforcing rib 73, an ornament or the like is arranged in the space on the back side. It becomes possible to do. Since it becomes possible to arrange light emitting elements such as LEDs in the space on the back side, it is possible to improve the production effect.

  Furthermore, since a thin portion 72 having a thickness smaller than that of the thick portion 70 is formed between the thick portion 70 and the outer peripheral edge reinforcing rib 73, the thickness of the thick portion 70 and the thickness of the thin portion 72 are formed. The amount of synthetic resin can be reduced by the difference between the two. Thereby, the game board 30 can be further reduced in weight. Further, since the space can be provided on the back side of the thin portion 72 by the amount that the thickness of the thin portion 72 is set to be smaller than the height of the outer peripheral edge reinforcing rib 73, a decoration or the like is arranged in the space on the back side. It becomes possible. Since it becomes possible to arrange light emitting elements such as LEDs in the space on the back side, it is possible to improve the production effect.

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

  An inclined surface portion 71 is formed on the outer periphery of the thick portion 70. The inclined surface portion 71 is set so as to gradually decrease in thickness from the thick portion 70 toward the outer side, and is coupled to the thin portion 72. Thereby, at the time of shaping | molding the game board 30, it can suppress that the deformation | transformation by the difference in the thickness of the thick part 70 and the thin part 72 arises. That is, the game board 30 is molded by melting and filling synthetic resin into the cavity of the molding die, and after being cured, the molded body is taken out from the molding die. The cooling rate of the molded body is faster in the thin portion 72 having a smaller thickness than the thick portion 70 having a larger thickness, so that residual stress is generated due to the difference in cooling rate, and the game board 30 is likely to be deformed such as warpage. However, the occurrence of residual stress due to the difference in 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, the game board 30 can be hardly deformed such as warpage.

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

  Since the protrusion 68a is formed around the hole 68, the plate thickness around the hole 68 can be increased. As a result, the load per unit area applied by the fitting pin to the inner periphery of the hole 68 can be reduced, so that it is difficult for cracks to occur around the hole 68 (particularly the thin portion 72). Moreover, since the depth of the hole 68 (the front-back direction of the game board 30) can be increased by the protrusion 68a, the holding force of the fitting pin can be increased. Thereby, the outer rail part 31 and the inner rail part 32 can be firmly fixed to the board surface of the game board 30.

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

  In addition, a fitting pin spot-welded to the inner rail portion 32 is inserted into a hole 68 formed in the protrusion 68 a formed at the boundary between the thick portion 70 and the inclined surface portion 71. By providing the thick portion 70 on the inner side of the inner rail portion 32 where the game area PE is formed, it is possible to secure a holding force such as a nail or a windmill. By providing a protrusion 68a (hole 68) into which a fitting pin spot welded to the inner rail portion 32 is inserted at the boundary between the thick portion 70 and the inclined surface portion 71, the area of the thick portion 70 is excessive. Can be prevented from increasing. By preventing the thick portion 70 from expanding outside the area where the game area PE is formed (inside the inner rail portion 32), the amount of synthetic resin forming the game board 30 is reduced, and the mass of the game board 30 is reduced. It can prevent becoming larger than necessary.

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

  The hole 69 is a portion into which a fitting convex portion 55 (described later) of the guide portion reinforcing member 50 is inserted, and is formed through the thin portion 72. Since the protrusion 69a is formed around the hole 69, the plate thickness around the hole 69 can be increased. As a result, since the load per unit area applied by the fitting convex portion to the inner periphery of the hole 69 can be reduced, it is difficult for cracks to occur around the hole 69 (thin portion 72). Further, since the depth of the hole 69 (the front-rear direction of the game board 30) can be increased by the protruding portion 69a, the holding force of the fitting convex portion 55 can be increased. Thereby, the guide part reinforcement member 50 can be firmly fixed to the board surface of the game board 30.

  The outer peripheral edge reinforcing rib 73 is formed with recessed portions 73a, 73b, 73c in which a part of the end surface on the back side (the front side in FIG. 7) is recessed in the height direction (the height of the rib is reduced). . The depressions 73a and 73c are formed at positions opposed to the outer peripheral reinforcement ribs 73 (left and right ribs), and the depression 73b intersects with the outer peripheral reinforcement ribs 73 (left and right ribs) formed with the depressions 73a and 73c. The outer peripheral edge reinforcing rib 73 (lower rib) is formed. Since the depressions 73a and 73c are formed at positions opposite to the outer peripheral reinforcement rib 73, the molded game board 30 is placed with the outer peripheral reinforcement rib 73 facing down on a table having a flat surface on the upper surface. (With the back side facing down), a gap is formed between the flat surface and the game board 30 (outer peripheral edge reinforcing rib 73) by the recessed portions 73a and 73c. A fingertip or the like of a hand can be inserted into the gap, and the game board 30 placed on the flat surface can be lifted using the inserted fingertip or the like as a clue.

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

  The opening 62 is a through hole to which the protruding pin 60 is attached, and is formed at two positions on the game board 30 at diagonal positions. A reinforcing rib 62a is erected around the opening 62 toward the back side, and the reinforcing rib 62a is continuous with the outer peripheral wall reinforcing rib 62a.

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

  On the other hand, when the reinforcing ribs 39a and 62a and the protrusions 68a and 69a are not formed, when the game board 30 receives a load on the board surface, bending deformation occurs in the thick part 70 and the thin part 72. When the deformation becomes 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, the height of the reinforcing ribs 39a and 62a and the protrusions 68a and 69a is set to be substantially the same as the height of the peripheral edge reinforcing rib 73, so Since it can suppress that bending deformation arises in the part 72, 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 in the game board 30, so a specific place on the board surface of the game board 30 Even when a concentrated load is applied, it is possible to prevent a large bending deformation from occurring on the surface of the game board 30. Thereby, it is possible to prevent the game board 30 from being damaged by a load applied to the game board 30 when a nail is implanted 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 an end view of the cut portion of the game board 30 taken along the line IX-IX in FIG. As shown in FIG. 9, the projecting pin 60 is a substantially columnar member formed by a member separate from the game board 30, and a flange portion 60 a that projects in the radial direction (left and right direction in FIG. 9) from the outer peripheral surface; A fitting insertion portion 60b extending from the flange portion 60a to the other side in the axial direction is continuously provided. The fitting part 60 b is a part that is inserted into the opening part 62, and the flange part 60 a is a part for regulating the insertion depth of the fitting part 60 b that is inserted into the opening part 62. On the other hand, the board surface of the game board 30 is formed with a recessed part 62b for receiving the flange part 60a. The recessed portion 62b is continuously provided around the opening 62 with a depth substantially the same as the thickness of the flange portion 60a. In addition, the diameter of the protruding pin 60 is formed slightly smaller than the diameter of the fitting insertion portion 60b (the inner diameter of the opening 62).

  The reinforcing rib 62a has an end surface on the back side (lower side in FIG. 9) set to a height position substantially the same as an end surface on the rear side (lower side in FIG. 9) of the peripheral portion reinforcing rib 73. Thereby, since the depth (FIG. 9 up-down direction) of the opening part 62 can be enlarged, the insertion depth by which the fitting insertion part 60b is inserted by the opening part 62 can be enlarged. On the other hand, when the reinforcing rib 62 a is not formed, the depth of the opening 62 is the same as the plate thickness of the thin portion 72. In that case, as compared with the present embodiment, the holding force for holding the fitting insertion portion 60b in the opening portion 62 is reduced, and the protruding pin 60 is likely to rattle or come off. By providing the reinforcing rib 62a as in the present embodiment, it can be prevented.

  Further, since the gaming board 30 in which the insertion part 60b is inserted into the opening 62 has the flange part 60a, the protruding pin 60 protrudes from the board surface of the gaming 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 (lower side in FIG. 9). Since the diameter of the protruding pin 60 is slightly smaller than the diameter of the fitting insertion portion 60b (inner diameter of the opening 62), when a plurality of game boards 30 are stacked, the board surface of one game board 30 is The protruding projecting pins 60 are inserted into the recesses (holes) in the reinforcing ribs 62a from the back side of the other game boards 30. As a result, it is possible to prevent displacement of the game boards 30 stacked in a flat state in the board surface direction.

  It should be noted that by configuring the projecting pin 60 as a separate member from the game board 30 as in the present embodiment, the game board after the game board 30 is molded until the projecting pin 60 is fitted into the opening 62 is provided. The protruding pins 60 can be prevented from protruding from the 30 board surfaces. This prevents the projecting pin 60 from interfering with the transport of the game board 30 or the projecting pin 60 from being damaged until the projecting pin 60 is fitted into the opening 62 after the game board 30 is molded. it can. In addition, after the projecting pin 60 is fitted into the opening 62, the projecting pin 60 can be removed from the opening 62 if the projecting pin 60 is not necessary when the pachinko machine 1 is assembled. Thereby, the assembly etc. of the pachinko machine 1 can be performed smoothly.

  Further, when the game board 30 is formed, the protruding pins 60 can be formed integrally with the game board 30. When the projecting pin 60 is fitted (inserted) into the game board 30 as in the present embodiment, it is necessary to prepare the projecting pin 60 as a separate member and insert the projecting pin 60 into the game board 30. On the other hand, by forming the protruding pin integrally with the game board, it is not necessary to prepare the protruding pin 60 as a separate member, so the number of parts can be reduced. Moreover, the operation | work which inserts the protrusion pin 60 in the game board 30 can be made unnecessary.

  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 in a molding die, and an outer peripheral edge reinforcing rib 73 is erected on the back side of a flat board surface (front surface). When the game board 30 made of synthetic resin is stacked and transported, there is a problem that the position shifts easily and the game board 30 made of wooden plywood stacks and transports. This is because the synthetic resin game board 30 is more slippery because it has a higher surface smoothness and a smaller friction coefficient than a wooden plywood game board.

  On the other hand, according to the present embodiment, the game board 30 is stacked by inserting the protruding pin 60 of one game board 30 into the recess (hole) in the reinforcing rib 62a of the other game board 30. Easy to carry. Moreover, since it is easy to insert a fingertip or the like of the hand into the gap formed by the recess 73a formed on the end surface of the outer peripheral reinforcing rib 73, the game board 30 can be easily lifted. Moreover, since the recessed parts 73a and 73c are formed in the opposing position of the outer periphery reinforcement rib 73, it can lift with good balance by inserting the fingertip etc. of a hand from right and left to the recessed parts 73a and 73c. Furthermore, since the recessed part 73b is formed in the outer periphery reinforcement rib 73 (located in FIG. 7 lower side) which cross | intersects the outer periphery reinforcement rib 73 (located in FIG. 7 right and left) in which the recessed parts 73a and 73c were 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 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. FIG. The guide portion reinforcing member 50 is a member for preventing the outer rail portion 31 that the game ball launched from the game ball launching device 21 collides first from swinging. Since the guide part reinforcing member 50 is addressed to the outer rail part 31, the swinging of the outer rail part 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) belt-like thin plate, and a fitting pin 31a is spot-welded to the side edge in the longitudinal direction of the outer rail portion 31 at an appropriate interval. The fitting pin 31 a is inserted into a hole 68 formed in the game board 30, whereby the outer rail part 31 is erected on the game board 30.

  Moreover, the outer rail part 31 is provided with the bending part 31b by which the edge of the longitudinal direction was bent and it was return | folded by the substantially U shape. The bent portion 31b is a portion for preventing the end edge in the longitudinal direction of the outer rail portion 31 from swinging, and guides the outer rail portion 31 through which the game ball launched from the game ball launching device 21 is guided. It is bent to the opposite surface side (back surface side) of the surface 31c. Thereby, when the game ball launched from the game ball launching device 21 collides with the guide surface 31c of the outer rail portion 31, the edge side of the outer rail portion 31 tilts to the opposite surface side (back side) of the guide surface 31c. Can be prevented.

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

  Next, the detailed structure of the guide part reinforcement member 50 is demonstrated. As shown in FIGS. 11 and 13, the guide portion reinforcing member 50 is a synthetic resin member, and is formed in a substantially trapezoidal shape when viewed from the front (as viewed from the board surface side of the game board 30) and the outer rail portion. The base part 51 located on the opposite surface side of the guide surface 31c of 31, the opposite surface side protruding part 52 standing on the base part 51, and the direction in which the opposite surface side protruding part 52 stands. It mainly includes a fitting convex portion 55 protruding from the base portion 51 in the opposite direction.

  The base portion 51 is a plate-like portion that is in close contact with the board surface of the game board 30 and is disposed along the outer rail portion 31, and the opposite-side protruding portion 52 stands substantially perpendicular to the base portion 51. It is a site | part provided in the edge part of the base | substrate part 51 at the same time as it is provided. The opposite-surface-side projecting portion 52 is provided along the outer rail portion 31, and the base portion 51 extends on the rear end side in a direction away from the outer rail portion 31. As a result, the base portion 51 and the opposite-surface-side protruding portion 52 are formed in a substantially L-shape when viewed from the side.

  The opposite-surface-side projecting portion 52 has at least one inclined portion 52a that slopes downward from the top toward the base portion 51 side (board surface side), and is connected to the inclined portion 52a and faces the outer rail portion 31. A contact portion 52b with which the portion comes into contact. A fitting convex portion 55 projects from one side edge of the base portion 51 and the opposite surface side projecting portion 52. Further, a rod-like columnar portion 53 is erected along the opposite surface side protruding portion 52 on the other side edge facing the base portion 51 and one side edge of 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 surface side of the contact portion 52b. Accordingly, it is possible to make it difficult to bend and deform the opposite-surface-side protruding portion 52 with respect to the axial direction of the columnar portion 53 as compared with the case where the columnar portion 53 is not formed.

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

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

  In the base portion 51, the length of one side edge on which the fitting convex portion 55 is projected is set shorter than the length of the other side edge facing the one side edge. By connecting the other side edge of the base part 51 to the bottom side of the columnar part 53 and the reinforcing part 54, the bottom area of the base part 51 gradually increases from one side edge to the other side edge of the base part 51. It is set to be. By making the bottom area of the base portion 51 far from the fitting convex portion 55 larger than the bottom area of the base portion 51 near the fitting convex portion 55, the bottom of the base portion 51 far from the fitting convex portion 55 is obtained. Insufficient area can be prevented. As a result, it is possible to suppress the swing of the opposite-side protruding portion 52 at a position far from the fitting convex portion 55.

  Since the guide portion reinforcing member 50 includes the base portion 51 disposed along the outer rail portion 31, the base portion 51 is located with respect to the position of the axis of the fitting convex portion 55 as shown in FIG. Can be shifted to the end (bending portion 31 b) side of the outer rail portion 31. As a result, the position of the fitting pin 31a that fixes the outer rail portion 31 to the game board 30 and the position of the opposite-surface-side protruding portion 52 (contact portion 52b) can be brought closer. By bringing the contact portion 52b closer to the fitting pin 31a that fixes the outer rail portion 31, the outer rail portion 31 can be 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 convex portion 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. It is formed in a column shape. The fitting convex part 55 is formed with a rounded reduced diameter part 55a at the tip. The reduced diameter portion 55a is a portion that is set so that the area of the cross section perpendicular to the axis gradually decreases as it goes toward the tip side. Since the reduced diameter portion 55 a is formed, the fitting convex portion 55 can be easily inserted into the hole 69. Moreover, since the fitting convex part 55 and the hole part 69 are formed in cross-sectional substantially circular shape, the fitting convex part 55 can be rotated with respect to the hole part 69, and the guide part reinforcement member 50 is made. Fine position adjustment when inserting into the hole 69 can be omitted. As a result, the workability of the insertion work of the guide portion reinforcing member 50 into the hole 69 can be improved.

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

  As shown in FIG. 12, the fitting convex part 55 is equipped with the recessed part 56 in which a part of outer peripheral surface was formed in the hollow shape. Since a part of the outer peripheral surface of the fitting convex portion 55 is formed in a hollow shape by the concave portion 56, when the fitting convex portion 55 is fitted into the hole 69, the outer peripheral surface of the fitting convex portion 55 and the hole portion 69 are formed. The contact area with the inner peripheral surface can be reduced. As a result, the vertical effectiveness per unit area of the hole 69 and the fitting convex 55 when fitting the fitting convex 55 into the hole 69 can be increased. Thereby, when fitting the fitting convex portion 55 into the hole 69, the hole 69 or the fitting convex portion 55 can be easily deformed (elastically deformed or plastically deformed). It can be easily fitted into the hole 69.

  Moreover, since the recessed part 56 is formed along the axial direction of the fitting convex part 55, the effect of the recessed part 56 mentioned above can be acquired along the axial direction of the fitting convex part 55. FIG. Furthermore, since the concave portion 56 is formed from the distal end of the fitting convex portion 55 to the proximal end, the effect of the concave portion 56 can be obtained from the distal end of the fitting convex portion 55 to the proximal end.

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

  Further, in the present embodiment, the sliding direction of the concave portion 56 viewed from the axial direction of the fitting convex portion 55 (the vertical direction in FIG. 12) is arranged 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 traveling toward the game area PE along the guide surface 31c of the belt-shaped outer rail portion 31, the fitting protrusion The part 55 can be hardly elastically deformed. Thereby, it is difficult to tilt the guide portion reinforcing member 50.

  That is, the fitting convex portion 55 is hardly elastically deformed by a load parallel to the sliding direction, and is easily elastically deformed by a load orthogonal to the sliding direction. This is because when a load parallel to the sliding direction is applied to the fitting convex portion 55, the fitting convex portion 55 is deformed so as to reduce the gap between the slit-like concave portions 56. Therefore, if the guide portion reinforcing member 50 is arranged so that the sliding direction of the fitting convex portion 55 is parallel to the longitudinal direction of the outer rail portion 31, the guide surface 31c of the outer rail portion 31 is pushed to the opposite surface side. When this is done, the outer rail portion 31 tends to tilt due to the elastic deformation of the fitting convex portion 55. On the other hand, if the guide portion reinforcing member 50 is arranged so that the sliding direction of the fitting convex portion 55 is not parallel to the longitudinal direction of the outer rail portion 31, the guide surface 31c of the outer rail portion 31 is the opposite surface. It is possible to make the fitting convex portion 55 difficult to elastically deform when pushed to the side. Thereby, it is difficult to tilt the guide portion reinforcing member 50.

  In particular, by making the longitudinal direction of the outer rail portion 31 and the sliding direction of the concave portion 56 orthogonal, the fitting convex portion 55 can be hardly elastically deformed by a load parallel to the sliding direction. Thereby, it can suppress that the guide part reinforcement member 50 tilts together as the outer rail part 31 tilts. As a result, the outer rail portion 31 can be prevented from tilting with the progress of the game ball, and the trajectory and flight distance of the game ball traveling along the outer rail portion 31 can be stabilized.

  By making the longitudinal direction of the outer rail portion 31 and the sliding direction of the concave portion 56 non-orthogonal, 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 and the sliding direction of the concave portion 56 parallel, the elastic deformation of the fitting convex portion 55 can be most actively utilized. As the outer rail portion 31 tilts due to the progress of the game ball, the guide reinforcing member 50 (opposite side protruding portion 52) is tilted together to elastically deform the fitting convex portion 55, and the fitting convex portion 55 With the restoring force, it is possible to restore the guide portion reinforcing member 50 (opposite surface side protruding portion 52) and the outer rail portion 31 to their original positions. By utilizing the elastic deformation of the fitting convex portion 55, it is possible to suppress the guide portion reinforcing member 50 from being damaged by a load that is repeatedly input (a load by the game ball). As a result, the tilt of the outer rail portion 31 can be prevented from being restricted by the guide portion reinforcing member 50, and the trajectory and flight distance of the game ball traveling along the outer rail portion 31 can be stabilized.

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

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

  Note that a part of the end surface is recessed from the hole 68 (inner peripheral surface) to the outer peripheral surface at the end surface of the protrusion 68a in which the fitting pin 31a fixed to the outer rail portion 31 is inserted into the hole 68. An end face groove 68b is formed. The end surface groove portion 68 b is formed in a direction along the longitudinal direction of the outer rail portion 31 disposed on the board surface of the game board 30. Since the end surface groove portion 68b is formed on the end surface of the protruding portion 68a, it is difficult to make a mistake in the direction in which the outer rail portion 31 is disposed when the outer rail portion 31 is disposed 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 31 c side of the outer rail portion 31 so as to face the opposite surface side projecting portion 52 and is in contact with the guide surface 31 c. A portion 57 is provided. As shown in FIGS. 11 and 13, the guide surface side protruding portion 57 protrudes from a part of the base end side (front side in FIG. 11) of the fitting convex portion 55 in the axial direction. A groove portion 58 into which the outer rail portion 31 is inserted is formed between the guide surface side protruding portion 57 and the opposite surface side protruding portion 52.

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

  Since the guide portion reinforcing member 50 includes the guide surface side protruding portion 57, the outer rail portion 31 is held in the groove portion 58 between the opposite surface side protruding portion 52 and the guide surface side protruding portion 57. Since the outer rail portion 31 is held from both sides by the opposite surface side protruding portion 52 and the guide surface side protruding portion 57 of the guide portion reinforcing member 50, it is possible to reliably prevent the outer rail portion 31 from tilting.

  Further, since the guide surface side protruding portion 57 disposed on the guide surface 31c side of the outer rail portion 31 is set lower than the height of the opposite surface side protruding portion 52, the game ball B along the guide surface 31c. Can be prevented from being obstructed by the guide surface side protruding portion 57. If the game ball B interferes with the guide surface side projecting portion 57, the kinetic energy of the game ball B is lost and the flight distance of the game ball B guided to the game area PE becomes unstable, but this can be prevented. The flight distance of the game ball B guided to the game area PE can be prevented from becoming unstable.

  As shown in FIG. 14, the concave portion 56 is formed in a slit shape from the front end (lower side in FIG. 14) of the fitting convex portion 55, leaving the base end (base end portion 55b) of the solid fitting convex portion 55. Is formed. Thereby, the base end part 55b of the solid fitting convex part 55 can be fitted to the hole 69 (board surface side). By fitting the base end portion 55 b of the solid fitting convex portion 55 into the hole portion 69 (board surface side), it is possible to prevent the fitting convex portion 55 from rattling with respect to the hole portion 69. Furthermore, since the concave portion 56 is formed on the distal 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 clearance between the outer peripheral surface of the fitting convex portion 55 (base end portion 55 b) and the hole 69 is an outer portion held in the groove portion 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 opposite surface side protruding portion 52 or the guide surface side protruding portion 57. While preventing the fitting convex portion 55 (base end portion 55 b) inserted in the hole 69 from rattling, when the outer rail portion 31 is fixed to the game board 30, the opposite side protruding portion 52 and the guide are provided. This is for facilitating insertion of the outer rail portion 31 into the groove portion 58 between the surface side protruding portions 57. 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 reinforcing member 50 that restricts the tilting of the outer rail portion 31 includes the fitting convex portion 55 that fits into the hole 69 that is formed in a hollow shape on the board surface of the game board 30, and the fitting convex portion. And an opposite-surface-side protruding portion 52 that protrudes from the portion 55 and contacts the opposite surface side of the guide surface 31 c of the outer rail portion 31. The guide portion reinforcing member 50 is configured so that the fitting convex portion 55 is fitted into a hole 69 formed in a hollow shape on the board surface of the game board 30, and the opposite surface side protruding portion is projected from the fitting convex portion 55. 52 contacts the opposite surface side of the guide surface 31 c of the outer rail portion 31. Thereby, it can suppress that the guide surface 31c is pushed by the other surface side by the game ball which progresses toward the game area | region PE along the guide surface 31c, and the strip | belt-shaped outer rail part 31 tilts outside. Since the tilt of the outer rail portion 31 that guides the game ball to the game area PE can be suppressed, the trajectory and flight distance of the game ball 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 traveling toward the game area PE along the guide surface 31c and the belt-shaped outer rail portion 31 tilts, the trajectory of the game ball changes or the game ball 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 so that the opposite surface side protruding portion 52 contacts the opposite surface of the guide surface 31c of the outer rail portion 31. It is possible to suppress the outer rail portion 31 from being tilted by a game ball that progresses along the 31c toward the game area PE. Thereby, the trajectory and flight distance of the game ball guided to the game area PE can be stabilized.

  Moreover, since the fitting convex part 55 is equipped with the recessed part 56 in which a part of outer peripheral surface was formed in the hollow shape, the fitting convex part 55 when fitting the fitting convex part 55 in the hole 69 is carried out. 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 convex 55 when fitting the fitting convex 55 into the hole 69 can be increased. Thereby, when fitting the fitting convex portion 55 into the hole 69, the hole 69 or the fitting convex portion 55 can be easily deformed (elastically deformed or plastically deformed). It can be easily fitted into the hole 69.

  Moreover, since the recessed part 56 is formed in the shape of a slide from the front-end | tip of the fitting convex part 55 toward the base end (base end part 55b), it utilizes the elastic deformation of the fitting convex part 55 by sliding. The fitting projection 55 can be fitted into the hole 69. As a result, the fitting convex portion 55 can be easily fitted into the hole 69, and a gap between the hole 69 and the fitting convex portion 55 is prevented by utilizing the elastic deformation of the fitting convex portion 55. As a result, the fitting convex portion 55 fitted in the hole 69 can be made less likely to rattle.

  In addition, since the sliding direction 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, it follows the guide surface 31 c of the belt-like outer rail portion 31. Thus, when the guide surface 31c is pushed to the opposite surface side by the game ball traveling 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 tilts. As a result, the trajectory and flight distance of the game ball guided to the game area PE can be further stabilized.

  Moreover, since the guide part reinforcement member 50 is provided with the guide surface side protrusion part 57 which opposes the opposite surface side protrusion part 52, the outer rail part 31 is hold | maintained from both the guide surface 31c and an opposite surface. Thereby, tilting of the outer rail part 31 can be prevented reliably. As a result, the trajectory and flight distance of the game ball guided to the game area PE can be further stabilized. Further, since the guide surface side projecting portion 57 is set to be lower than the height of the opposing surface side projecting portion 52, the interference between the game ball along the guide surface 31c and the guide surface side projecting portion 57 is prevented. it can.

  Further, the opposite-surface-side protruding portion 52 has an inclined portion 52a that is inclined downward from the top toward the axially outer side of the fitting convex portion 55, and an opposite surface of the outer rail portion 31 that is connected to the inclined portion 52a. Since the contact portion 52b that contacts at least a part of the opposite surface is provided, the operation of arranging the guide portion reinforcing member 50 and the outer rail portion 31 on the board surface of the game board 30 can be facilitated.

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

  Next, the outer rail portion 31 is disposed along the inclined portion 52 a of the opposite-side protruding portion 52 so that the outer rail portion 31 faces the contact portion 52 b of the guide portion reinforcing member 50. The inclined portion 52a is inclined downward from the top toward the axially outer side of the fitting convex portion 55, and the contact portion 52b is connected to the inclined portion 52a. Therefore, the outer rail portion 31 extends along the inclined portion 52a. Can be smoothly arranged on the contact portion 52b.

  In addition, when the outer rail portion 31 is moved in the direction orthogonal to the board surface of the game board 30 to bring the outer rail portion 31 closer to the game board 30, if the side edge of the outer rail portion 31 comes into contact with the inclined portion 52a, the outer rail As the part 31 approaches the game board 30, the inclined part 52 a is pushed in the horizontal direction with respect to the board surface, and the guide part reinforcing member 50 rotates around the fitting convex part 55. When the outer rail portion 31 is separated from the inclined portion 52a and faces the contact portion 52b, a force for rotating the guide portion reinforcing member 50 is not generated, so that the position of the guide portion reinforcing member 50 is determined.

  Further, while fitting the outer rail portion 31 in the groove portion 58 between the contact portion 52b and the guide surface side protruding portion 57, the fitting pin 31a fixed to the outer rail portion 31 is inserted into the hole 68. Go. As the fitting pin 31 a is inserted into the hole 68, the proximal end surface of the fitting convex portion 55 is pushed to the side edge of the outer rail portion 31, and the fitting convex portion 55 is gradually inserted into the hole 69. . Thereby, workability | operativity of the arrangement | positioning operation | work which arrange | positions the outer rail part 31 on the board surface of the game board 30 can be improved.

  In addition, since the base end part 55 b of the fitting convex part 55 is formed in a solid shape, the base end part 55 b is fitted into the hole 69. Thereby, it can prevent that the fitting convex part 55 rattles in the hole part 69. FIG.

  Further, the thin portion 72 of the game board 30 has a protruding portion 69a protruding toward the back side, and the protruding portion 69a and the thin portion 72 have a hole 69 formed therethrough, so that the hole 69 is fitted into the protruding portion 69a. The fitting depth of the fitting convex part 55 can be ensured. As the fitting depth of the fitting convex portion 55 fitted into the hole 69 increases, the fitting convex portion 55 fitted into the hole 69 tends not to swing in the direction orthogonal to the axial direction. Therefore, by securing the fitting depth of the fitting convex portion 55 fitted in the hole 69, the guide portion reinforcing member 50 fixed to the game board 30 can be made difficult to swing. By making it difficult for the guide portion reinforcing member 50 fixed to the game board 30 to swing, 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 The trajectory and flight distance can be further stabilized.

  Further, since the protrusion 69a is coupled to the thin portion 72, and the hole 69 is formed through the protrusion 69a and the thin portion 72, the area of the thick portion 70 is increased in order to form the hole 69. It can be made unnecessary. Although the mass of the game board 30 increases by the amount of the protrusion 69a (excluding the hole 69) coupled to the thin part 72, it is not necessary to increase the area of the thick part 70. The increase can be suppressed. Furthermore, since the protruding portion 69a through which the hole 69 is formed has a function of a rib that increases the rigidity of the thin portion 72 around the hole 69, the rigidity of the thin portion 72 around the hole 69 can be secured. Therefore, the game board 30 can be reduced in weight while securing the holding power of the nail by planting the nail in the thick portion 70 and 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, with reference to FIG. 15, the guide part reinforcement member 50 in other embodiment is demonstrated. In addition, about the part same as 1st Embodiment, the same code | symbol is attached | subjected and the following description is abbreviate | omitted. FIG. 15A is a partially enlarged rear view of the game board 30 in which the guide portion reinforcing member 80 is installed in another embodiment, and FIG. 15B is a game in which the guide portion reinforcing member 90 in another embodiment is installed. 3 is a partially enlarged rear view of the board 30. FIG. 15 (a) and 15 (b), the fitting convex portions 85 and 95 of the guide portion reinforcing members 80 and 90 are fitted into the hole 69 formed in the game board 30 from the board surface (front surface) side. And the state seen from the back side of game board 30 is illustrated.

  The guide portion reinforcing member 80 shown in FIG. 15A is a part of the outer peripheral surface along the axial direction (FIG. 15A perpendicular direction to the paper surface) at two axially symmetrical positions on the outer peripheral surface of the fitting convex portion 85. Is provided with a recess 86 formed in a hollow shape. Since the fitting convex part 85 is provided with the recessed part 86 in which a part of outer peripheral surface was formed in the hollow shape, the outer peripheral surface of the fitting convex part 85 when fitting the fitting convex part 85 into the hole 69. And the contact area between 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 fitting the fitting protrusion 85 into the hole 69 can be increased. Thereby, when fitting the fitting convex portion 85 into the hole 69, the hole 69 or the fitting convex portion 85 can be easily deformed (elastic deformation or plastic deformation). It can be easily fitted into the hole 69.

  In addition, a recessed portion 85 a having a circular cross section is formed at the approximate center of the fitting convex portion 85 from the tip of the fitting convex portion 85 along the axial direction of the fitting convex portion 85. By reducing the cross-sectional area of the fitting convex portion 85 by the recessed portion 85a, the fitting convex portion 85 can be easily elastically deformed by the vertical effect acting on the fitting convex portion 85. Thereby, since the fitting convex part 85 can be further easily fitted in the hole part 69, workability | operativity when fitting the fitting convex part 85 in the hole part 69 can be improved. Furthermore, by making the fitting convex portion 85 easily elastically deformed, it is possible to prevent the fitting convex portion 85 from rattling with respect to the hole 69.

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

  A guide reinforcing member 90 shown in FIG. 15 (b) has a part of the outer peripheral surface along the axial direction (FIG. 15 (b) perpendicular to the paper surface) at four positions of the axially symmetrical position of the outer peripheral surface of the fitting convex portion 95. Is provided with a recess 96 formed in a hollow shape. Since the fitting convex part 95 is provided with the recessed part 96 by which a part of outer peripheral surface was formed in the hollow shape, the outer peripheral surface of the fitting convex part 95 when fitting the fitting convex part 95 in the hole 69 And the contact area between 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 fitting the fitting protrusion 95 to the hole 69 can be increased. Accordingly, when fitting the fitting convex portion 95 into the hole 69, the hole 69 or the fitting convex portion 95 can be easily deformed (elastically deformed or plastically deformed). It can be easily fitted into the hole 69.

  In addition, a recessed portion 95 a having a circular cross section is formed at the approximate center of the fitting projection 95 from the tip of the fitting projection 95 along the axial direction of the fitting projection 95. By reducing the cross-sectional area of the fitting convex portion 95 by the recess 95a, the fitting convex portion 95 can be easily elastically deformed by the vertical effect acting on the fitting convex portion 95. Thereby, since the fitting convex part 95 can be further easily fitted in the hole part 69, workability | operativity when fitting the fitting convex part 95 in the hole part 69 can be improved. Furthermore, by making the fitting convex portion 95 easily elastically deformed, it is possible to prevent the fitting convex portion 95 from rattling with respect to the hole 69.

  Next, a second embodiment will be described with reference to FIG. In the first embodiment, the outer peripheral edge of the opening 61 penetrating 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). Explained the case. 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. In addition, about the part same as 1st Embodiment, the same code | symbol is attached | subjected and the following description is abbreviate | omitted. FIG. 16 is a front view of a game board 130 and a structure 170, which are the main components of the pachinko machine 1 in the second embodiment.

  As shown in FIG. 16, the gaming board 130 has an opening 161 that is formed through the gaming board 130 in the thickness direction (perpendicular to the plane of FIG. 16) and a part of the outer peripheral edge of the gaming board 130 is opened. The structure 170 which connects the periphery of the opening part 161 is provided. 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 at the periphery of the opening 161 of the game board 130 and another predetermined portion 161b. In the present embodiment, the structure 170 is formed in a substantially rectangular shape when viewed from the front, and connects two locations of the opening 161 along the outer peripheral edge of the game board 130. Note that the game board 130 and the structure 170 are made of a synthetic resin having translucency, similarly to the game board 30 described in the first embodiment. In addition, a symbol display device 43a (see FIG. 5) is arranged inside the opening 161 whose outer peripheral edge is partially 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. In FIG. 17, the structure 170 is shown separated from the game board 130. As shown in FIG. 17, the structure 170 has a main body portion 172 formed in a substantially rectangular parallelepiped box shape, and projects from the front side of the main body portion 172 up and down (in a direction substantially parallel to the board surface of the game board 30) on both sides. It is mainly provided with an engaging portion 171 formed in a bowl shape.

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

  An insertion hole 174 through 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 in the structure 170 is formed on a part of the periphery of the opening portion 161. The connection part 131 is a part for engaging the engaging part 171 provided in the structure 170 to position the structure 170.

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

  A light scattering portion 132 is provided on the back side of the connecting portion 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 by a protrusion provided in a vertical direction or a horizontal direction, a protrusion provided in a direction intersecting the vertical and horizontal directions, or a wavy protrusion.

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

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

  Light emitted from the light emitting unit 181 (indicated by a two-dot chain line in FIG. 18) enters and exits the light scattering unit 132 (the engaged portion 131) due to a difference in refractive index between air and the light scattering unit 132. Sometimes refracts. Therefore, if the light emission part 181 is made to light-emit, the electrical decoration of the state by which many light was disperse | distributed or the state with a three-dimensional effect is realizable. Thereby, in addition to the effect by the symbol display part 173 (decoration part), the effect by the light from the light emission part 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 portion 132 can be integrally formed with the game board 130 when the game board 130 is formed. As a result, the light scattering portion 132 can be easily manufactured.

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

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

  Further, by scattering light at the light scattering portion 132, the shadow of a shaft-like member (not shown) such as a screw that is screwed into the insertion holes 133 and 174 is caused from the board surface of the game board 130 or the front surface of the structure 170. It can prevent being visually recognized. This is because the light can be circulated in front of an axial member (not shown) by scattering the light with the light scattering portion 132. Thereby, it is possible to make it difficult to visually recognize the joint portion (the connecting portion 131 and the engaging portion 171) between the game board 130 and the structure 170 due to the light scattered by the light scattering portion 132, and between the game board 130 and the structure 170. The production effect of the seam portion can be improved.

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

  Here, in the conventional structure in which components such as a display device and an accessory are attached to the surface of the game board, since the breadth in the depth direction is scarce, it is easy to adopt a similar effect, and it is difficult to enhance the interest of the game. In addition, in a game board made of conventional wooden plywood (veneer), considering the workability and mechanical strength of the wooden plywood, a structure that provides an opening that opens a part of the outer periphery of the game board is adopted. hard.

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

  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. The 170 symbol display unit 173 (decoration unit) can realize not only a planar 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. Furthermore, since the structure 170 is unitized as a game part having the symbol display part 173 (decoration part), the structure 170 can be easily attached to the game board 130, replaced, or the like.

  Next, with reference to FIG.19 and FIG.20, the game board 130 and structure 190 in other embodiment are demonstrated.

The shaft portion 193 is fitted into the gear 194, and the rotating body 192 and the shaft portion 193 are configured to be rotatable integrally with the gear 194. The gear 194 is engaged with a worm 195, and the worm 195 is configured to be rotatable by a motor 196. Accordingly, when the motor 196 is rotated, the worm 195 is rotated, and the gear 194 engaged with the worm 195 is rotated, so that the shaft portion 193 and the rotating body 192 are rotated.

  If the rotation of the motor 196 is set so as to be triggered by the winning of a game ball to the through chucker (starting port) 36, etc., various effects by the symbol display device 43a and the rotating body 192 (movable effect member) can be produced. It can be realized.

  In addition, since the drive unit (motor 196) of the rotating body 192 is arranged using the space in the thickness direction of the game board 130, the space for arranging the drive unit (motor 196) in the limited space of the pachinko machine 1 Can be used effectively. As a result, the degree of freedom in designing the rotating body 192 (movable effect member) visually recognized by the player who plays the game facing the game board 130 can be improved, and various effects can be realized.

  Further, the structure 190 is provided with a ball passage 197 through which a game ball passes in the vertical direction. The ball passage 197 communicates with a ball passage 162 (a game ball passes) provided in the game board 130. Since the game ball can be guided to the structure 190 by the ball passage 197, the interest of the game can be improved.

  The ball passage 197 interferes with the movement of the game ball to reduce the flow velocity of the game ball or change the flow direction of the game ball (such as a clown or a stage, a nail, a windmill, a warp). Route, etc.) can be provided.

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

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

  In addition, the end surface formed in the axial direction end surface of the protrusion part 69a holding the fitting convex part 55 of the guide part reinforcement member 550, and the axial direction end surface of the protrusion part 68a holding the fitting pin 31a of the outer rail part 31. The groove portion 68b (see FIG. 12) also functions as a receiving portion for the rail receiver (a part of the back-side contact portion). The height from the board surface 530a is also set to the same value as the height of the receiving portion 532c.

  Next, FIG. 30 (a) is a partially enlarged rear view of the game board 530 showing an enlarged portion indicated by XXXa in FIG. 26, and FIG. 30 (b) is a game board seen from the direction of arrow XXXb in FIG. FIG. 530 is a partially enlarged side view of 530. In FIG. 30A, the outer rail portion 31 arranged on the surface of the game board 530 (the surface on the back side of FIG. 30A) is indicated by a broken line.

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

  The rail receiver 534 is formed in the vicinity of a reference hole 534a (see FIG. 30) that serves as a positioning reference in the manufacturing process of the game board 530 and the like, and is continuous with the outer peripheral edge reinforcing rib 531. The rail receiver 534 is a part for receiving a side edge of the outer rail portion 31 of another game board 530 when a plurality of game boards 530 having the outer rail portion 31 and the inner rail portion 32 mounted thereon are stacked. The rail receiver 534 has a semi-cylindrical shape, and protrudes from the back surface of the game board 530 along the thickness direction of the game board 530 (FIG. 30A, the direction perpendicular to the paper surface).

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

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

  Next, FIG. 31A is a partially enlarged rear view of the game board 530 showing the portion indicated by XXXIa of FIG. 26 in an enlarged manner, and FIG. 31B is a line XXXIb-XXXIb of FIG. 31A. It is a cutting part end view. In FIG. 31 (a), the inner rail portion 32 arranged on the board surface of the game board 530 (FIG. 31 (a) the back surface of the paper surface) is indicated by a broken line.

  As shown in FIG. 31A, the rail receiver 532 is provided on the inclined surface portion 71 of the game board 530, and the hole 68 for mounting the inner rail portion 32 is provided in the axial direction (FIG. 31A). (Perpendicular to the paper surface). Around the out port 39, annular reinforcing ribs 535 are erected on the back surface of the game board 530, and the holes 68 are formed on the left and right sides of the out port 39. Thereby, the inner rail part 32 can be firmly fixed to the game board 530 on both sides of the out port 39 into which the game balls that could not enter the entrance part provided in the game area PE flow.

  The inner rail portion 32 includes a bay portion 32 a where the inner rail portion 32 is bent toward the outer peripheral edge of the game board 530 at the position of the out port 39. The bay exit portion 32a is a part for facilitating the flow of game balls into the out port 39, and the game balls that have flowed down the game area PE and reached the lower end of the inner rail portion 32 are output by the bay output portion 32a. 39 can be quickly introduced.

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

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

  Next, a state when a plurality of game boards 530 are stacked will be described with reference to FIG. 32 and FIG. FIG. 32 and FIG. 33 (a) are end views of a cut portion schematically showing a state in which a plurality of game boards 530 are stacked. In the manufacturing process of the game board 530, first, holes 68 for attaching the fitting pins 31a, 32a and the like and nails (fault nails) 536 are inserted into a board material for a game board made of synthetic resin. A pilot hole (mounting hole) is formed. Next, the nail 536 is planted, and a small part (not shown) such as a windmill, the outer rail portion 31 and the inner rail portion 32 are attached. Next, large components (not shown) such as a large winning device or a control circuit board are assembled. Assembling large parts complicates the work, so the process capability decreases. Due to the imbalance of the process capability, the game board 530 in the middle of manufacture may temporarily stay between processes. In such a case, the game board 530 in the middle of manufacture to which the nail 536, the outer rail part 31, and the inner rail part 32 are attached is temporarily stacked, and the game board 530 that has been waiting for the next process is put on standby.

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

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

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

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

  The rail receivers 532, 533, and 534 (receiving portions 532c, 533a, and 534c) are stacked when a plurality of game boards 530 are stacked so that the back surface of the game board 530 and the board surface 530a of another game board 530 face each other. The height in the thickness direction of the game board 530 is set so that the nail 536 planted on the board surface 530a is not in contact with the back surface of the game board 530. As a result, the load on the upper game board 530 applied to the nail 536 of the lower game board 530 stacked can be reduced to zero. As a result, when the game boards 530 are stacked, it is possible to reliably prevent adverse effects such as bending of the nail 536 implanted in the game board 530.

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

  In addition, the rail receivers 532 and 534 have receiving surfaces 532a1, 532b1 and 534b extending in the thickness direction of the game board 530 from the receiving portions 532c and 534c along the longitudinal side surfaces of the outer rail portion 31 and the inner rail portion 32. Has been. As a result, when the positions of the stacked game boards 530 are shifted in the direction orthogonal to the longitudinal direction of the outer rail portion 31 and the inner rail portion 32, the receiving surfaces 532 a 1, 532 b 1, and 534 b become the outer rail portion 31 and the inner rail portion 32. At the end, further misalignment of the game board 530 is prevented. As a result, it is possible to maintain the state in which the side edges of the outer rail portion 31 and the inner rail portion 32 are in contact with the receiving portions 532c and 534c, so that it is possible to suppress the upper gaming board 530 stacked from sliding down.

  In addition, the outer rail portion 31 and the inner rail portion 32 are provided with fitting pins 31 a and 32 a protruding from the side edges of the outer rail portion 31 and the inner rail portion 32 toward the outer side in the width direction of the outer rail portion 31 and the inner rail portion 32. On the other hand, the game board 530 is formed with a hole 68 into which the fitting pins 31a and 32a are fitted, and the fitting pins 31a and 32a are fitted and inserted into the hole 68 so that the outer rail part 31 and the inner rail are inserted into the game board 530. The rail part 32 is attached. Since the hole 68 is formed at the position of the rail receivers 532 and 533, the depth of the hole 68 can be secured by the height of the rail receivers 532 and 533 in the thickness direction of the game board 530. Thereby, the holding force of fitting pin 31a, 32a inserted by the hole 68 can be enlarged. Therefore, the outer rail portion 31 and the inner rail portion 32 can be firmly fixed to the game board 530 by firmly fixing the fitting pins 31 a and 32 a to the game board 530.

  Further, since the relief portions 535a wider than the receiving portion 532c are formed on the left and right sides of the reinforcing rib 535 (see FIG. 31A), the protruding portions 32a formed on the inner rail portion 32 are stacked. Interference with the reinforcing rib 535 of the game board 530 can be prevented. Moreover, since the escape part 535a (refer FIG.31 (b)) is set so that the height from the board surface 530a is lower than the receiving part 532c, the height of the baying part 32a (FIG. 31 (a) perpendicular | vertical direction of a paper surface). Can be prevented from interfering with the escape portion 535a of the stacked game board 530 even if the value is set to a value larger than the height of the inner rail portion 32. Accordingly, it is possible to prevent the curved portion 32a from having an adverse effect such as the bay portion 32a being plastically deformed and changing its shape while the plurality of game boards 530 are stacked and waiting.

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

  On the other hand, when the height of the outer peripheral rail receivers 531c and 531d in the thickness direction of the game board 530 is set to a value larger than the height of the outer peripheral reinforcing rib 531, the game board 530 is placed on the flat surface G. The game board 530 is rattled. The game board 530 can solve this problem, and can prevent the play board 530 placed flat on the flat surface G with the outer peripheral edge reinforcing rib 531 downward and can be stably placed. Further, when lifting the flat game board 530, the fingertips inserted into the outer peripheral rail receivers 531c and 531d can be used as clues, and the handling of the game board 530 being manufactured or the completed game board 530 can be improved. It can be improved.

  Further, the outer peripheral rail receivers 531c and 531d are set to have the same height in the thickness direction of the game board 530 as the rail receivers 532, 533 and 534 (receiving portions 532c, 533a and 534c). When a plurality of game boards are stacked such that the back surface of the game board 530 and the board surface 530a of another game board 530 face each other, the board surfaces 530a of the plurality of game boards 530 can be made substantially parallel. As a result, the plurality of game boards 530 can be stacked substantially vertically, and the stacked game boards 530 can hardly be slid down. Further, the outer rail portion 31 of the game board 530 is prevented from interfering with the outer peripheral rail receivers 531c and 531d of the stacked game boards 530. As a result, it is possible to prevent adverse effects such as deformation of the outer rail portion 31 while the plurality of game boards 530 are stacked and waited.

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

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

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

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

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

  In this case, the outer rail portion 31 is railed so that only the region U is in contact with the rail receiver 532 of the other game board 530, and the portion other than the area U is not in contact with the rail receiver 532 of the other game board 530. Set the height of the receiver 532 and the like. The inner rail portion 32 sets the height of the rail receiver 532 or the like so as to abut on the rail receiver 532 or the like of another game board 530. As a result, the area U of the outer rail portion 31 and the inner rail portion 32 come into contact with the rail receiver 532 and the like of other game boards 530, so that a plurality of game boards 530 are stacked. Thereby, in the outer rail portion 31, the load of the stacked game boards 530 is applied to a portion (a portion other than the region U) that greatly affects the trajectory of the game ball that is driven from the game ball launching device 21 into the game region PE. Can be prevented. As a result, it is possible to prevent a part (part other than the area U) that has a great influence on the trajectory of the game ball to be driven into the game area PE from being adversely affected by the load of the stacked game boards 530.

  Further, in addition to the rail receiver 532 arranged in the region U of the outer rail portion 31, a rail receiver 534 (see FIG. 26) arranged in the vicinity of the region U of the outer rail portion 31 is used to stack the gaming boards 530. It is possible to support the outer rail portion 31. Since the rail receiver 534 is provided in the reference hole 534a and the area of the receiver 534c (FIG. 30) can be secured, when supporting the outer rail 31, the rail receiver 534 is compared with the case where the rail receiver 534 is not used. Thus, the load acting on the unit area of the outer rail portion 31 can be reduced. Thereby, compared with the case where the rail receiver 534 is not used, the area U of the outer rail portion 31 can be hardly adversely affected by the load of the stacked game boards 530.

  In the present embodiment, the region U of the outer rail portion 31 abuts on the rail receiver 532 of the other game board 530, and the portion other than the region U (outer rail portion 31) is the rail receiver 532 of the other game board 530. In the above description, the height of the rail receiver 532 is set so as to be non-contact with the rail receiver 532. However, the region U of the outer rail portion 31 is also configured to be non-contact with the rail receiver 532 of the other game board 530. It is naturally possible to set the height of the receiver 532. Thereby, since the load of the stacked game boards 530 can be prevented from being applied to the outer rail portion 31, it is possible to prevent the outer rail portions 31 from being adversely affected by the load of the stacked game boards 530. Since the game board 530 is supported by the inner rail portion 32, the rail receiver 532, and the like that hardly affect the trajectory of the game ball, the trajectory of the game ball can be stabilized even if the inner rail portion 32 is plastically deformed. .

  Next, another embodiment will be described with reference to FIG. In 6th Embodiment, the case where the game board 530 was mounted on the outer rail part 31 and the inner rail part 32 by the outer periphery rail receiver 531d and the rail receiver 532 was demonstrated. In contrast, in another embodiment shown in FIG. 33 (b), the case where the game board 560 is placed on the outer rail portion 31 and the passage forming member 538 by the outer peripheral rail receivers 531d and 531f will be described. In addition, about the part same as what was demonstrated in 6th Embodiment, the same code | symbol is attached | subjected and the following description is abbreviate | omitted. FIG. 33B is a cut end view schematically showing a state in which a plurality of game boards 560 according to another embodiment are stacked.

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

The outer peripheral rail receiver 531f is a part for receiving a passage forming member 538 fixed to the board surface of another game board 560 when a plurality of game boards 560 are stacked, and the height from the board surface is the outer peripheral rail. It is set to the same value as the receptacle 531d.

  The game board 560 includes a hole 68 formed so as to penetrate in the thickness direction, and a protrusion 537 is provided around the hole 68. The axial length (FIG. 33B, vertical direction) of the protrusion 537 is set to a value shorter than the axial length of the rail receiver 532 (see FIG. 33A). Therefore, when a plurality of game boards 530 are stacked, the side edge (upper end) of the inner rail portion 32 provided on the game board 560 and the protruding portion 537 are not in contact with each other. Accordingly, the game board 560 is placed on and stacked on the outer rail portion 31 and the passage forming member 538 by the outer peripheral rail receivers 531d and 531f. Since the outer peripheral rail receiving members 531d and 531f are provided on the outer peripheral reinforcing rib 531, even if the outer rail portion 31 and the passage forming member 538 are arranged so as to protrude to the outer peripheral edge of the game board 560, the game board 560 Can be prevented from interfering with the outer rail portion 31 and the passage forming member 538 and the outer peripheral edge reinforcing rib 531. Thereby, the game area PE of the game board 560 can be greatly expanded.

  Next, another embodiment of the rail receiver 532 will be described with reference to FIG. In the sixth embodiment, a case has been described in which the protrusions 532a and 532b facing each other are provided on the receiving portion 532c formed on the end surface in the axial direction of the rail receiver 532. On the other hand, FIG. 34 demonstrates the case where one of the protrusions 532a and 532b protrudes from the receiving part 532c. In addition, about the part same as 6th Embodiment, the same code | symbol is attached | subjected and the following description is abbreviate | omitted. 34 (a) and 34 (b) are cut end views schematically showing a state in which a plurality of game boards 570 and 580 according to another embodiment are stacked.

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

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

  Next, with reference to FIGS. 35 and 36, the guide portion reinforcing member 550 fixed to the board surface 530a of the game board 530 will be described. The guide portion reinforcing member 550 is a member for reinforcing the outer rail portion 31. In the first embodiment, the inclined portion 52a coupled to the contact portion 52b of the guide portion reinforcing member 50 is formed with substantially the same width with respect to the distance away from the fitting convex portion 55 when viewed from the front. Explained the case. In contrast, in the present embodiment, a case will be described in which the inclined portion 553 is formed so that the width in the front view increases as the distance from the fitting convex portion 55 increases. In addition, about the part same as what was demonstrated in 1st Embodiment, the same code | symbol is attached | subjected and the following description is abbreviate | omitted. FIG. 35A is a partially enlarged front view of the game board 530 to which the guide portion (outer rail portion 31) and the guide portion reinforcing member 550 are fixed, and FIG. 35B is a line XXXVb-XXXVb of FIG. It is a cutting part end view of the guide part (outer rail part 31) and the guide part reinforcement member 550 in FIG.

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

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

  Next, with reference to FIG. 36, a method of mounting the guide portion reinforcing member 550 and the outer rail portion 31 to the game board 530 will be described. 36 (a) is a partially enlarged front view of the game board 530 showing a state in which the guide portion reinforcing member 550 is fixed, and FIG. 36 (b) fixes the guide portion (outer rail portion 31) and the guide portion reinforcing member 550. It is the elements on larger scale of game board 530 which shows the state to do. In FIG. 36A, the position of the outer rail portion 31 arranged on the game board 530 is indicated by a two-dot chain line.

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

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

  Further, when the outer rail portion 31 is brought close to the board surface 530a, the outer rail portion 31 is accommodated in the groove portion 58 between the contact portion 552 and the guide surface side protruding portion 57. In this state, when the outer rail portion 31 is further brought closer to the board surface 530a, the base end side end surface (the bottom surface of the groove portion 58) of the fitting convex portion 55 is pushed to the side edge of the outer rail portion 31, and the fitting convex portion 55 is It is gradually inserted into the hole 69. Thereby, workability | operativity of the arrangement | positioning operation | work which arrange | positions the outer rail part 31 to the board surface 530a of the game board 530 can be improved.

  Thus, the force that causes the outer rail portion 31 to approach the board surface 530a by the inclined portion 553 provided so as to be offset radially outward with respect to the fitting convex portion 55 serving as the rotation center is used as the fitting convex portion. The force can be changed to a force for rotating the guide reinforcing member 550 around 55. As a result, before the outer rail portion 31 is arranged, in the operation of temporarily placing the fitting convex portion 55 of the guide portion reinforcing member 550 into the hole 69 of the game board 530, the position of the inclined portion 553 is set to the outer rail. What is necessary is just to make it overlap with the position where the part 31 is arrange | positioned. Therefore, it is possible to hardly require the accuracy of the alignment of the guide portion reinforcing member 550 (the angle adjustment of the contact portion 552 with respect to the fitting convex portion 55 serving as the rotation center) in the temporarily arranging operation. As a result, the outer rail part 31 and the guide part reinforcing member 550 can be smoothly arranged on the board surface 530a of the game board 530, and the workability of the arrangement work can be improved.

  In addition, the inclined portion 553 is formed so that the distance from the contact portion 552 increases as the distance from the fitting convex portion 55 increases. That is, the inclined portion 553 is formed to have a narrower width on the fitting convex portion 55 side when viewed from the front, and to increase in width as the distance from the fitting convex portion 55 increases. As a result, the alignment in the operation of temporarily placing the guide portion reinforcing member 550 on the game board 530 by the extent that the width of the inclined portion 553 opposite to the fitting convex portion 55 can be increased (the fitting convex portion serving as the rotation center). The accuracy of the angle adjustment of the contact portion 552 with respect to 55 can be reduced. As a result, it is possible to shorten the time required for the positioning of the work of temporarily placing the guide portion reinforcing member 550 on the game board 530, and the placement work of the outer rail portion 31 and the guide portion reinforcing member 550 can be made efficient.

A guide reinforcement member is fixed to the surface of the game board. The guide part reinforcing member has a fitting convex part fitted into a hole formed in a hollow shape on the board surface of the game board, and the opposite side protruding part protruding from the fitting convex part is a guide part of the guide part. Touch the opposite side of the surface. Thereby, it can suppress that a guide surface is pushed by the other surface side by the game ball which progresses toward a game area | region along a guide surface, and a strip | belt-shaped guide part tilts. Since the tilting of the guide unit that guides the game ball to the game area can be suppressed, the trajectory and flight distance of the game ball guided to the game area can be stabilized.

  In other words, when the guide surface is pushed to the opposite side by the game ball moving 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 side of the guide surface of the guide portion, the game area is moved along the guide surface. It can suppress that a guide part tilts with the game ball which advances toward. Thereby, the trajectory and flight distance of the game ball guided to the game area can be stabilized.

  In the gaming machine A1, the fitting convex portion includes a concave portion in which a part of the outer peripheral surface is formed in a hollow shape.

  According to the gaming machine A2, since the concave portion is formed in a hollow shape in a part of the outer peripheral surface of the fitting convex portion, the outer peripheral surface of the fitting convex portion when fitting the fitting convex portion into the hole portion and The contact area with the inner peripheral surface of the hole can be reduced. As a result, the vertical effect per unit area of the hole and the fitting protrusion when fitting the fitting protrusion into the hole can be increased. This makes it easy to deform (elastic deformation or plastic deformation) the hole or fitting protrusion when fitting the fitting protrusion into the hole, so that in addition to the effect of the gaming machine A1, the fitting There exists an effect which can make a fitting convex part fit easily in a hole.

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

  According to the gaming machine A3, since the concave portion is formed in a sliding shape from the front end to the base end of the fitting convex portion, it is fitted into the hole portion using the elastic deformation of the fitting convex portion due to the sliding. The mating convex portion can be fitted. As a result, in addition to the effects of the gaming machine A1 or A2, the fitting convex portion can be easily fitted into the hole portion, and the hole and the fitting convex portion can be obtained by utilizing the elastic deformation of the fitting convex portion. Since it can prevent that a clearance gap arises, there exists an effect which can make it difficult to rattle the fitting convex part fitted by the hole.

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

  According to the gaming machine A4, the guide portion reinforcing member is arranged so that the sliding direction of the concave portion viewed from the axial direction of the fitting convex portion is arranged in non-parallel to the longitudinal direction of the guide portion. When the guide surface is pushed to the opposite surface side by the game ball that progresses 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 the flight distance of the game ball guided to the game area can be further stabilized.

  That is, the fitting convex portion is hardly 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 part reinforcing member is arranged so that the sliding direction of the fitting convex part is parallel to the longitudinal direction of the guiding part, when the guide surface of the guiding part is pushed to the opposite side, the fitting convex part The guide part tends to tilt due to the elastic deformation of the part. 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, the guide surface of the guide portion is pushed to the opposite surface side. The fitting convex portion can be made difficult to elastically deform. Thereby, it is possible to make it difficult to tilt the guide portion to the opposite surface side of the guide surface.

  In any one of the gaming machines A1 to A4, the guide portion reinforcing member is disposed on the guide surface side of the guide portion so as to face the opposite surface side projecting portion and contacts the guide surface. A gaming machine A5 comprising a projecting portion, the guide surface side projecting portion being set lower than the height of the opposite surface side projecting portion.

  According to the gaming machine A5, the guide surface side projecting portion disposed on the guide surface side of the guide portion facing the opposite surface side projecting portion contacts the guide surface of the guide portion. The guide part is held between the guide part and the guide surface side projecting part. Since the guide portion is held from both the guide surface and the opposite surface by the guide portion reinforcing member, 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 the flight distance of the game ball guided to the game area can be further stabilized.

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

  In any one of the gaming machines A1 to A5, the opposite-surface-side protruding portion is connected to a contact portion that faces the opposite surface of the guide portion and contacts at least a part of the opposite surface, and the contact portion. And an inclined portion that descends downward from the top toward the outside of the fitting convex portion in the axial direction.

  According to the gaming machine A6, when the guide part reinforcing member and the guide part are arranged on the board surface of the game board, first, the fitting convex part of the guide part reinforcing member is inserted into the hole part of the game board. Subsequently, a guide part is arrange | positioned along the inclination part of an opposing surface side protrusion part so that an opposite surface may face the contact part of a guide part reinforcement member. The inclined part is inclined downward from the top part toward the outside of the fitting convex part in the axial direction, and the contact part is connected to the inclined part, so that the guide part is smoothly arranged on the contact part along the inclined part. Can be made. As a result, in addition to the effect of any of the game boards A1 to A5, the guide part can be smoothly arranged on the board surface of the game board, and the workability of arranging work for arranging the guide part 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 has a thick part where nails are planted on the board surface, and the thick part is connected to the thick part. A thin portion whose thickness is set to be smaller than the portion, an outer peripheral reinforcing rib standing on the back side from the outer periphery of the thin portion, and a protrusion that is coupled to protrude from the predetermined portion of the thin portion to the back side A gaming machine A7, wherein the hole is formed through the thin portion and the protruding portion.

  According to the gaming machine A7, since the nail is planted on the board surface of the thick portion located on the back side of the game area, the nail holding power can be secured by securing the nail driving depth. In addition, since a thin part that is set to be thinner than the thick part is connected to the thick part, a game board that does not have a thin part (a game board that is uniformly formed with the thickness of the thick part) Compared to, the game board can be reduced in weight. Furthermore, since the outer peripheral edge reinforcing rib is erected from the outer peripheral edge of the thin part to the back side, the rigidity of the thin part can be ensured. Thereby, while ensuring rigidity, a game board can be reduced in weight and the retention strength of the nail implanted by the board surface can be improved.

  In addition, the protrusion protrudes from the predetermined part of the thin part to the back side, and the protrusion is coupled, and the hole is formed through the thin part and the protrusion, so that the fitting convex part that fits into the hole is fitted. 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 the direction perpendicular to the axial direction. By securing the fitting depth of the fitting convex portion 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 part reinforcing member fixed to the game board to swing, it is possible to suppress tilting of the guide part that guides the game ball to the game area, so the trajectory and the flight distance of the game ball guided to the game area can be reduced. It can be further stabilized.

  In addition, since the protrusion protrudes from the predetermined part of the thin part to the back side and the protrusion is formed and the hole is formed through the protrusion and the thin part, the area of the thick part is increased to form the hole. Can be made unnecessary. Although the mass of the game board increases by the amount of the protrusion (excluding the hole) coupled to the thin part, it is not necessary to increase the area of the thick part, so an increase in the mass of the game board can be suppressed. . Furthermore, since the projecting portion through which the hole is formed has the function of a rib that enhances the rigidity of the thin portion around the hole, the rigidity of the thin portion around the hole can be ensured.

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

  In the gaming machine A6, the inclined portion is provided so as to be offset with respect to the fitting convex portion radially outward with the fitting convex portion as a rotation center.

  According to the gaming machine A8, 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 portion of the game board and temporarily arranged. . At the time of temporary arrangement, the position of the inclined portion is overlapped with the position where the guide portion is arranged. Next, in order to arrange the guide portion, the side edge of the guide portion is brought close to the board surface while abutting against the inclined portion. Since the inclined part is provided so as to be offset radially outward with respect to the fitting convex part as the rotation center, as the guide part is brought closer to the board surface, the inclined part is pushed by the guide part and is fitted. The guide reinforcing member rotates about the joint convex portion. When the side edge of the guide part is separated from the inclined part, the rotation of the guide part reinforcing member stops, and the guide part and the guide part reinforcing member are arranged on the board surface.

  In this way, the inclined portion provided so as to be offset radially outward with respect to the fitting convex portion serving as the rotation center causes the guide portion to be guided around the fitting convex portion with the force that brings the guide portion close to the board surface. It can be replaced with a force for rotating the reinforcing member. As a result, in the operation of temporarily placing the fitting convex portion of the guide portion reinforcing member into the hole portion of the game board before arranging the guide portion, the position of the inclined portion overlaps with the position where the guide portion is arranged. You can do that. For this reason, it is possible to hardly require the accuracy of the alignment of the guide portion reinforcing member (the angle adjustment of the contact portion with respect to the fitting convex portion serving as the rotation center) in the temporarily arranging operation. As a result, in addition to the effects achieved by the game board A6, the guide part and the guide part reinforcing member can be smoothly arranged on the board surface of the game board, and the workability of the arrangement work of arranging the guide part and the guide part reinforcing member on the board surface There is an effect that can be improved.
