When the operation handle 51 is rotated clockwise by the player, the touch sensor 51a is turned on and the resistance value of the variable resistor changes in accordance with the amount of rotation operation, and the resistance value of the variable resistor is changed. The ball is fired at an intensity (firing intensity) corresponding to (i), whereby the ball is hit on the front surface of the game board 13 with a flying amount corresponding to the operation of the player. When the operation handle 51 is not operated by the player, the touch sensor 51a and the firing stop switch 51b are off.

  At the lower front part of the lower plate 50, a ball release lever 52 for operating when discharging the balls stored in the lower plate 50 downward is provided. The ball-pulling lever 52 is always urged in the front direction. By sliding the ball-pulling lever 52 in the rearward direction against the urging, the bottom opening formed on the bottom surface of the lower plate 50 is opened. The ball falls naturally from the bottom opening and is discharged. The operation of the ball removing lever 54b is usually performed in a state where a box (generally referred to as a "thousand boxes") for receiving the balls discharged from the lower plate 50 is placed below the lower plate 50.

  As shown in FIG. 2, the game board 13 has a base plate 60 cut into a substantially square shape in a front view, a number of ball guide nails (not shown), a windmill, rails 61 and 62, and a general prize. The opening 63, the first winning opening 64, the second winning opening 640, the variable winning device 65, the through gate 67, the variable display device unit 80, etc. are assembled, and the periphery thereof is the back surface of the inner frame 12 (see FIG. 1). Attached to the side. The base plate 60 is made of a light-transmissive resin material, and is formed so that a player can visually recognize various structures disposed on the back side of the base plate 60 from the front side. The general winning opening 63, the first winning opening 64, the second winning opening 640, the variable winning device 65, and the variable display device unit 80 are disposed in through holes formed in the base plate 60 by router processing. It is fixed with a tapping screw or the like from the front side.

  The front center portion of the game board 13 can be visually recognized from the front side of the inner frame 12 through the window 14c (see FIG. 1) of the front frame 14. Hereinafter, the configuration of the game board 13 will be described mainly with reference to FIG.

  An outer rail 62 formed by bending a band-shaped metal plate into a substantially arc shape is planted on the front surface of the game board 13, and a band-shaped metal plate similar to the outer rail 62 is provided inside the outer rail 62. The arc-shaped inner rail 61 formed by the above is planted. The inner rail 61 and the outer rail 62 surround the outer periphery of the front of the game board 13, and the front and rear are surrounded by the game board 13 and the glass unit 16 (see FIG. 1). A game area in which a game is played is formed by the behavior of. The game area is an area defined by two rails 61 and 62 and a resin outer edge member 73 connecting the rails (a winning opening and the like are provided and fired) on the front surface of the game board 13. The area where the falling ball flows down).

  The two rails 61 and 62 are provided to guide the ball fired from the ball firing unit 112a (see FIG. 4) to the upper part of the game board 13. A return ball preventing member 68 is attached to a tip portion (upper left portion of FIG. 2) of the inner rail 61 to prevent a situation in which a ball once guided to the upper portion of the game board 13 returns to the ball guide passage again. Is done. A return rubber 69 is attached to the tip of the outer rail 62 (upper right portion in FIG. 2) at a position corresponding to the maximum flight portion of the ball, and the ball fired at a predetermined momentum strikes the return rubber 69 and momentum. Is rebounded toward the center while being attenuated.

  First symbol display devices 37A and 37B each including a plurality of LEDs as light-emitting means and a 7-segment display are provided at a lower left portion of the game area as viewed from the front (a lower left portion in FIG. 2). The first symbol display devices 37A and 37B are for performing display according to each control performed by the main control device 110 (see FIG. 4), and mainly display the game state of the pachinko machine 10. In the present embodiment, the first symbol display devices 37A and 37B are configured to be selectively used according to whether the ball has won the first winning opening 64 or the second winning opening 640. Specifically, when the ball wins the first winning opening 64, the first symbol display device 37A operates, while when the ball wins the second winning opening 640, the first symbol display device 37A operates. The symbol display device 37B is configured to operate.

  In addition, the first symbol display devices 37A and 37B use LEDs to indicate whether the pachinko machine 10 is in the process of probable change, during working hours, or during normal operation, or to indicate whether or not the pachinko machine 10 is fluctuating. Whether the stop symbol is a symbol corresponding to a probable jackpot or a symbol corresponding to an ordinary jackpot is indicated by an illuminated state, the number of retained balls is indicated by an illuminated state, and a round during a jackpot is displayed by a 7-segment display device. Display number and error. In addition, the plurality of LEDs are configured so that the emission colors (for example, red, green, and blue) of each LED are different, and the combination of the emission colors may indicate various game states of the pachinko machine 10 with a small number of LEDs. it can.

  In the pachinko machine 10, the lottery is performed when the first winning port 64 and the second winning port 640 have a winning. In the lottery, the pachinko machine 10 determines whether or not it is a big hit (big hit lottery), and when it is determined to be a big hit, also determines the big hit type. As the jackpot type determined here, a 15R certain-variable jackpot, a 4R certain-variable jackpot, and a 15R regular large jackpot are prepared. The first symbol display devices 37A and 37B not only indicate whether or not the result of the lottery is a jackpot as a stop symbol after the end of the change, but if the jackpot is a jackpot, a symbol corresponding to the jackpot type is displayed. .

  Here, “15R probability variable jackpot” means a probability variable jackpot in which the maximum number of rounds shifts to the high probability state after 15 rounds of jackpot, and “4R probability variable jackpot” means a maximum round number of four rounds. Is a probable jackpot that transitions to a high probability state after. The “15R normal jackpot” refers to a jackpot in which the maximum number of rounds shifts to the low probability state after 15 rounds of jackpots and the time saving state is reached during a predetermined number of changes (for example, 100 changes). is there.

  The “high-probability state” refers to a state in which the subsequent jackpot probability increases as an added value after the end of the jackpot, that is, a state in which the probability is changing (probable change), in other words, a game that is easily shifted to the special game state. State. The high probability state (probable change) in the present embodiment includes a game state in which the winning probability of a second symbol, which will be described later, increases and a ball can easily enter the second winning opening 640. The “low-probability state” refers to a state in which the probability of a jackpot is normal, that is, a state in which the jackpot probability is lower than that in the case of a probability change. The time saving state (medium time saving) in the “low probability state” is a state in which the jackpot probability is a normal state, and the jackpot probability of the second symbol is increased while the jackpot probability remains unchanged. This refers to a game state in which the ball is easy to win. On the other hand, the state where the pachinko machine 10 is in the normal state is a state of the game in which the probability is not changed or the time is not reduced (a state in which neither the big hit probability nor the second symbol hit probability is increased).

  During probable change or during working hours, not only the probability of hitting the second symbol increases, but also the time during which the electric accessory 640a attached to the second winning opening 640 is opened is changed. Is set. When the electric accessory 640a is in the open state (open state), the ball wins in the second winning opening 640 as compared to when the electric accessory 640a is in the closed state (closed state). It will be in an easy state. Therefore, during a probability change or during a shortened working hours, the ball can easily enter the second winning opening 640, and the number of jackpot lotteries can be increased.

  In addition, during the probable change or during working hours, instead of changing the opening time of the motorized accessory 640a attached to the second winning opening 640, or in addition to changing the opening time, the power A change may be made to increase the number of times that the accessory 640a is released from the normal number. In addition, during the probability change or during working hours, the winning probability of the second symbol is not changed, and the electric accessory 640a associated with the second winning opening 640 is opened and the electric accessory 640a is opened once. At least one of the number of times may be changed. In addition, during probable change or during working hours, the time during which the motorized accessory 640a associated with the second winning opening 640 is opened or the number of times the electric accessory 640a is opened per hit is not determined. Only the probability may be changed so as to increase as compared with the normal state.

  In the game area, a plurality of general winning openings 63 are provided in which 5 to 15 balls are paid out as winning balls when the balls win. Further, a variable display device unit 80 is provided in a central portion of the game area. In the variable display device unit 80, the winning of the first winning opening 64 and the second winning opening 640 (start winning) as a trigger, while synchronizing with the fluctuation display on the first symbol display device 37A, 37B, the third symbol. A third symbol display device 81 composed of a liquid crystal display (hereinafter simply abbreviated as “display device”) that performs variable display, and an LED that varies and displays the second symbol when the ball of the through gate 67 passes through as a trigger. A second symbol display device (not shown) is provided.

  Further, a center frame 86 is arranged in the variable display device unit 80 so as to surround the outer periphery of the third symbol display device 81. The third symbol display device 81 can be visually recognized from an opening opening at the center of the center frame 86.

  The third symbol display device 81 is composed of a large 9-inch liquid crystal display. The display content is controlled by the display control device 114 (see FIG. 4), so that, for example, the upper, middle and lower 3 One symbol column is displayed. Each symbol row is composed of a plurality of symbols (third symbols), and these third symbols are horizontally scrolled for each symbol row, and the third symbol is variably displayed on the display screen of the third symbol display device 81. It has become. In the third symbol display device 81 of the present embodiment, the display of the game state accompanying the control of the main control device 110 (see FIG. 4) is performed by the first symbol display devices 37A and 37B. The decorative display corresponding to the display of the symbol display devices 37A and 37B is performed. Note that the third symbol display device 81 may be configured using, for example, a reel or the like instead of the display device.

  The second symbol display device alternately lights a symbol “O” and a symbol “X” as a display symbol (second symbol (not shown)) for a predetermined time each time the ball passes through the through gate 67. The variable display is performed. In the pachinko machine 10, when it is detected that the ball has passed through the through gate 67, a winning lottery is performed. If the result of the winning lottery is a winning, the symbol "O" is stopped and displayed on the second symbol display device after the variation display of the second symbol. If the result of the winning lottery is off, the symbol "x" is stopped and displayed on the second symbol display device after the variation display of the third symbol.

  In the case of the pachinko machine 10, when the variable display on the second symbol display device is stopped at a predetermined symbol (in this embodiment, a symbol of “○”), the electric accessory 640a attached to the second winning opening 640 is moved for a predetermined time. Only the operating state (opened).

  The time required for the fluctuation display of the second symbol is set to be shorter during the probable change or during the time reduction than during the normal game state. Thus, during the probable change and during the time reduction, the fluctuation display of the second symbol is performed in a short time, so that the winning lottery can be performed more than during the normal time. Therefore, since the chance of winning in the winning lottery increases, the player can be given many opportunities to open the electric accessory 640a of the second winning opening 640. Therefore, the ball can easily enter the second winning opening 640 during probable change and during working hours.

  In addition, during the probability change or during the working hours, the probability of winning is increased, and the opening time and the number of times of opening of the electric accessory 640a per hit are increased. When the ball is in a state where it is easy to win, the time required for the variable display of the second symbol may be constant regardless of the game state. On the other hand, in the case where the time required for the fluctuation display of the second symbol is set shorter during the probability change or during the time reduction, the hit probability may be constant irrespective of the game state, or one hit may be performed. The opening time and the number of times of opening of the electric accessory 640a may be constant regardless of the gaming state.

  The through gate 67 is assembled to the game board on the right side in the lower area of the variable display unit 80, and among the balls fired on the game board, a part of the ball flowing down the right side of the game board can pass through. Is configured. When the ball passes through the through gate 67, a winning lottery of the second symbol is performed. After the winning lottery, the variable display is performed on the second symbol display device, and if the result of the winning lottery is a hit, a symbol of “○” is displayed as a stop symbol of the variable display, and if the result of the winning lottery is out. For example, a symbol "x" is displayed as a stop symbol of the variable display.

  The number of times the ball has passed through the through gate 67 is retained up to a total of four times, and the number of retained balls is displayed by the above-mentioned first symbol display devices 37A and 37B and at the second symbol retaining lamp (not shown). Is also lit. Four second symbol holding lamps are provided for the maximum number of holdings, and are arranged symmetrically below the third symbol display device 81.

  The variable display of the second symbol is performed by switching on and off of a plurality of lamps in the second symbol display device as in the present embodiment, and is also performed by the first symbol display devices 37A and 37B and the third symbol display device. This may be performed using a part of the symbol display device 81. Similarly, the lighting of the second symbol holding lamp may be performed by a part of the third symbol display device 81. Further, the maximum number of reserved balls for passing the ball through the through gate 67 is not limited to four, but may be set to three or less, or five or more (for example, eight). The number of through gates 67 is not limited to one, but may be plural (for example, two). Further, the mounting position of the through gate 67 is not limited to the right side of the variable display unit 80, but may be, for example, the left side of the variable display unit 80. Further, since the number of reserved balls is indicated by the first symbol display devices 37A and 37B, the second symbol retaining lamp may not be lit.

  Below the variable display unit 80, a first winning port 64 in which a ball can win is provided. When a ball wins in the first winning opening 64, a first winning opening switch (not shown) provided on the back side of the game board 13 is turned on, and the main control device 110 is turned on by turning on the first winning opening switch. A jackpot lottery is performed in (see FIG. 4), and a display corresponding to the lottery result is shown on the first symbol display device 37A.

  On the other hand, on the right side of the first winning opening 64 in a front view, a second winning opening 640 where a ball can win is provided. When a ball wins in the second winning opening 640, a second winning opening switch (not shown) provided on the back side of the game board 13 is turned on, and the main control device 110 is turned on by turning on the second winning opening switch. A jackpot lottery is performed in (see FIG. 4), and a display corresponding to the lottery result is shown on the first symbol display device 37B.

Accordingly, when the game nail YK is driven into the recess 312, the contact resistance between the game nail YK and the recess 312 can be reduced, and the game nail YK can be held on the inner surface of the recess 312.

  Note that the gaming nail YK is driven upward into the base member 310 (winning opening unit 300) at an angle of 5 degrees upward (upward in FIG. 7A). Therefore, the recessed portion 312 is recessed and inclined 5 degrees downward from the front side to the back side.

  Two game nails YK are provided on the base member 310, and the head side of the nail protrudes into the game area. The two game nails YK are arranged above the upper ends of the side walls 321 of the ball winning member 320, which will be described later, and are set at the same height. Thereby, by adjusting the interval between the two game nails YK, the number of balls flowing into the first winning opening 64 can be adjusted with respect to the number of game balls flowing down the game area.

  The through holes 313 are through holes into which screws for fastening and fixing the winning opening unit 300 to the base plate 60 are inserted, and four through holes are formed in the peripheral portion of the base member 310. The through hole 313 is formed such that the diameter of the front surface is enlarged. Thereby, when the tip side (screw portion side) of the flathead screw is inserted from the front side of the through hole 313 and screwed to the base plate 60, it is possible to suppress the head of the flathead screw from projecting to the front side. Therefore, when the game ball flows down the game area, it is possible to suppress the flow of the game ball from being hindered by the plate screw. As a result, it is possible to stabilize the flow of the game ball flowing down the game area.

  The protrusions 314 are positioning protrusions for positioning the base plate 60 and the winning opening unit 300, and are formed on the left and right with the opening 310 interposed therebetween. A recess 60b (see FIG. 5) is formed in the base plate 60 at a position facing the projection 314. The concave portion 60b is formed to be concave in a circular shape having substantially the same inner diameter as the outer shape of the projection 314. Thereby, when the winning opening unit 300 before fastening is arranged on the base plate 60, the projection 314 is inserted inside the concave portion 60b when the winning opening unit 300 is fastened to the base plate 60. Can be positioned.

  The ball winning member 320 is formed of a side wall 321 protruding from the periphery of the through hole 311 to the front side (the right side in FIG. 7A) and a front wall 322 connecting the protruding tip side of the side wall 321. A first winning opening 64 is formed in a region surrounded by the front wall 322.

  The side wall 321 is formed in a U-shaped cross section with an open top, and the distance between opposing inner walls is formed larger than the diameter of the game ball. The front wall 322 is formed so as to close the protruding tip of the side wall 321. Therefore, the first winning opening 64 is formed in a mode in which the upper portion is opened.

  The side wall 321 is provided with a rolling portion 323 that is erected upward on the bottom surface (the lower surface in FIG. 7B). The rolling portion 323 is formed to have a constant thickness from the rear side (left side in FIG. 7B) end of the passage forming member 330 described later to the front wall 322.

  The rolling portion 323 is formed to be inclined upward toward the front side (front wall 322 side), and is formed at an intermediate position between the opposing side walls 321. As a result, the game balls flowing into the first winning opening 64 are thrown to the upper surface of the rolling portion 323 and rolled by the inclination of the rolling portion 323 to be thrown to the rear side.

  The passage forming member 330 is formed to protrude from the periphery of the opening 311 of the base member 310 to the rear side. The passage forming member 330 is formed in a substantially D-shape whose lower side is curved in a rear view, and a space large enough to allow a game ball to pass therethrough is formed inside. Thereby, the game balls flowing into the first winning port 64 can be sent to the back side of the passage forming member 330 and can be sent to the passage member (not shown) connected to the back side of the passage forming member 330.

  The passage forming member 330 has two bent portions (portions indicated by phantom lines S1 (see FIGS. 6 (b) and 7 (a)) located above (upper portion in FIG. 6) in rear view. It is located on the back side of the center position on the concave base end side of the setting portion 312. Further, bulging portions 331 bulging radially outward around the imaginary line S1 are formed at the two bent portions of the passage forming member 330. Thereby, the rigidity around the concave portion 312 can be increased. As a result, it is possible to prevent the winning opening unit 300 from being damaged by an impact when the gaming nail YK is driven into the recessed portion 312.

  Further, as described above, the gaming nail YK is provided in a direction non-parallel to the direction orthogonal to the plane of the base member 310 (in a direction inclined downward toward the distal end driven into the base member 310). Therefore, the tip portion is located below the virtual line S1. Thereby, the thickness of the bulging portion 331 located at the upper portion on the tip side of the gaming nail YK is increased. Therefore, the tip side of the gaming nail YK can be hardly displaced upward.

  Here, since the winning opening unit 300 is provided in the middle of the flow of the game ball from above, the game ball flowing down to the upper side of the game nail YK protruding toward the game area is more likely to collide. Therefore, an upward displacement force is likely to act on the tip portion of the game nail YK due to the impact of the game ball colliding with the upper portion of the game nail YK. Therefore, it is necessary to make the back side of the winning opening unit 300 in which the game nail YK is implanted thick, and there is a problem that the manufacturing cost of the winning opening unit 300 increases.

  On the other hand, in the present embodiment, the virtual line S1 (the bent portion at the upper end of the passage forming member 330) is arranged on the back side of the position where the gaming nail YK is driven, and bulges around the axis of the virtual line S1. Since the portion 331 is formed, it is not necessary to make the bulging portion 331 larger than necessary. As a result, an increase in the manufacturing cost of the winning opening unit 300 can be suppressed.

  In addition, the passage forming member 330 includes a guide portion 333 that is located below (the lower part in FIG. 6) (curved portion in a D-shape in rear view) and guides the rolling of the game ball that has won the first winning opening 64. The guide part 333 and the bulging part 331 are connected by the first connecting part 334.

  Thereby, the rigidity of the bulging portion 331 in the vertical direction can be increased. Therefore, when a game ball flowing down the game area collides with an upper part of the game nail YK protruding to the game area side, the displacement of the game nail YK in the vertical direction can be suppressed.

  Further, the passage forming member 330 includes a second connecting portion 335 that connects between the two bulging portions 331. Thereby, the rigidity of the bulging portion 331 in the direction (the left-right direction in FIG. 6B) connecting the two bulging portions 331 can be increased.

  The winning opening unit 300 is disposed below the central opening of the base plate 60 to which the center frame 86 is attached, as described above. Therefore, when a game ball flowing down around the center frame 86 flows into the first winning port 64, the game ball is sent from both left and right (left and right in FIG. 2) of the base plate 60 (game board 13). Therefore, when the game ball collides with the game nail YK, a force for displacing the game nail YK to the left and right is likely to act.

  When adjusting the amount of game balls flowing into the first winning opening 64, the game nail YK needs to change the gap between the two, and at this time, it is bent in the left and right direction. Therefore, from this point, a force in the left-right direction is likely to act on the gaming nail YK.

  In the present embodiment, since the two bulging portions 331 are connected by the second connecting portion 335, when a game ball flowing down from both left and right sides of the base member 60 collides with a game nail projecting into the game area. Also, when adjusting the interval between the two game nails YK, it is possible to suppress the game nails YK from being displaced in the left-right direction (the left-right direction in FIG. 6B) due to the impact.

  In the winning opening unit 300 configured as described above, the gaming nail YK disposed above the first winning opening 64 is driven into the base member 310 and disposed as described above. Therefore, when the game nail YK is broken or the game nail YK comes out of the base member 310 and a normal game cannot be performed, the countersunk screw inserted into the through hole 313 of the base member 310 is removed. By removing the winning opening unit 300 from the base plate 60 and attaching the winning opening unit 300 in a normal state to the base plate 60, a normal game can be performed.

  That is, the game nail YK, which is located above the first winning opening 64 and adjusts the number of game balls flowing into the first winning opening 64, is highly likely to break or fall off due to the adjustment. In this case, if only the game nail YK is replaced, the new game nail YK is driven into the same prepared hole (recessed portion 312), so that the force for holding the game nail YK is insufficient and the new game nail YK falls out immediately. There is fear.

  On the other hand, in the present embodiment, when the gaming nail YK is broken or dropped, the base member 310 in which the prepared hole (the concave portion 312) is formed can be replaced. Can be prevented from falling off immediately.

  Next, a second embodiment will be described with reference to FIGS. In the first embodiment, the case where the winning opening unit 300 is formed from one member has been described. However, in the second embodiment, the winning opening unit 2300 is formed from two members. The same parts as those in the above-described embodiments are denoted by the same reference numerals, and description thereof will be omitted.

  First, an arrangement position of the winning opening unit 2300 in the second embodiment will be described with reference to FIGS. FIG. 9 is a front view of the pachinko machine 10 according to the second embodiment. FIG. 10 is an exploded perspective front view of the pachinko machine 10. 9 and 10 illustrate a part of the game nail provided on the base plate 60. FIG. 10 shows a state where the center frame 86 and the winning opening unit 2300 are removed from the base plate 60.

  As shown in FIGS. 9 and 10, the base plate 60 in the second embodiment has a recess 2060 c penetrating below the center opening (FIG. 9 side) of the base plate 60 to which the center frame 86 is attached. It is formed. The winning opening unit 2300 is partially inserted into the recessed portion 2060c, and is fixed from the front side of the base plate 60 (on the front side in FIG. 9) with a tapping screw or the like.

  A recess 2360d is formed around the center opening side of the recess 2060c from the front side to the back side of the base plate 60. The recess 2360d has an outer shape in a front view substantially the same as an outer shape of a second winning member 2500 described later. Thus, the second winning member 2500 can be disposed inside the recess 2360d.

  In the recessed portion 2360d, a plurality of annular protrusions 2060d1 that are formed in an annular shape and protrude toward the front side are formed. The annular projection 2360d1 is formed such that a screw having the second winning member 2500 inserted therein can be fastened to its inner edge. In the present embodiment, four annular projections 2060d1 are formed in the recess 2360d.

  Next, the configuration of the winning opening unit 2300 will be described with reference to FIGS. 11A is a front view of the winning opening unit 2300, and FIG. 11B is a cross-sectional view of the winning opening unit 2300 along the line XIb-XIb in FIG. 11A, and FIG. 14 is a cross-sectional view of the winning opening unit 2300 taken along the line XIc-XIc in FIG. FIG. 12 is an exploded perspective front view of the winning opening unit 2300, and FIG. 13 is an exploded perspective rear view of the winning opening unit 2300. In FIG. 11C, the illustration of the second winning member 2500 is omitted.

  As shown in FIGS. 11 to 13, the winning opening unit 2300 is provided on the front side of the base plate 60 and has a first winning member 2400 into which the game nail YK is driven, and the front side of the first winning member 2400. And a second winning member 2500 having a first winning opening 64.

  The first winning member 2400 includes a main body 2410 formed of a substantially rectangular plate-like body in a front view, and a bulging portion 2420 bulging from the back side of the main body 2410. Further, a gaming nail YK is driven into the first winning member 2400 from the front side.

  The main body 2410 has a first recess 2411 recessed inward from both ends in the horizontal direction (left and right directions in FIG. 11A) when viewed from the front, and a recess formed inward from both ends in the gravity direction when viewed from the front. And a through hole 2413 penetrating in the thickness direction at four corners. Further, the distance dimension in the plate thickness direction of the main body 2410 is formed to be substantially the same as or smaller than the concave dimension of the concave portion 2060d of the base plate 60 on the back side. Thus, when the first winning member 2400 is disposed on the base plate 60, the front side of the main body 2410 can be suppressed from protruding toward the game area. As a result, it is possible to prevent the flow of the game ball from being hindered by the first winning member 2400.

  The first concave portion 2411 is formed at an intermediate position of the main body portion 2410 in the direction of gravity (the vertical direction in FIG. 11A). Thus, when the first winning member 2400 is fitted into the recess 2460d of the base plate 60, the contact surface between the first winning member 2400 and the base plate 60 can be increased. Therefore, it is possible to prevent the first winning member 2410 from being displaced in the direction of gravity with respect to the base plate 60.

  The second recessed portion 2412 is formed at an intermediate position in the horizontal direction (the left-right direction in FIG. 11A) of the main body 2410. Thus, the distance between the center frame 86 and the first winning opening 64 can be reduced. As a result, game balls flowing down from above the center frame 86 can easily flow into the first winning opening 64.

  The through hole 2413 is a hole into which the tip of the screw is inserted when the first winning member 2400 is fastened to the base plate 60. The diameter of the through hole 2413 is increased toward the front side (the right side in FIG. 11B). Accordingly, when a countersunk screw is inserted into the through hole 2413 from the front side of the first winning member 2400, the head of the screw can be inserted into the through hole 2413.

  Further, the through-hole 2413 includes a diameter-enlarging portion 2413a whose diameter is increased on the back side from the middle position in the thickness direction. The enlarged diameter portion 2413a is formed to have an inner diameter larger than the outer diameter of the above-described annular protrusion 2060d1, and has a concave dimension in the plate thickness direction (distance from the back surface of the main body portion 2410 to the concave bottom surface of the enlarged diameter portion 2413a). Are formed smaller than the projecting dimension of the annular projection 2060d1.

  Accordingly, when the first winning member 2400 is disposed inside the recessed portion 2360d, the annular projection 2360d1 can be inserted inside the enlarged diameter portion 2413a, and the concave bottom surface of the enlarged diameter portion 2413a and the annular projection 2360 can be inserted. Can be in contact with the protruding tip surface of As a result, the screw fastening position can be positioned on the front side by the protruding distance of the annular projection 2360d1, and the length of the tip end side of the screw can be shortened. In addition, since the concave bottom surface of the enlarged diameter portion 2413a and the protruding distal end surface of the annular projection 2360 are in contact with each other, the length of screwing can be increased accordingly, and the fastening force when fastening the screw is increased. Can be secured.

  The bulging portion 2420 is formed at a position overlapping the concave portion 2060c of the base plate 60 in the front-rear direction (the left-right direction in FIG. 11B). Further, the game nail YK is driven into a position overlapping the bulging portion 2420 in the front-rear direction. Thereby, the rigidity of the first winning member 2400 at the position where the gaming nail YK is driven can be increased. As a result, when the gaming nail YK is driven into the first winning member 2400, or when a game ball flowing down the downflow area collides with the gaming nail YK, it is possible to suppress the first winning member 2400 from being damaged.

  The second winning member 2500 mainly includes a base member 2510 formed of a rhombic plate in a front view, and a ball winning member 320 protrudingly formed on the front side (the right side in FIG. 11B) of the base member 2510. The base plate 2510 and the ball winning member 320 are integrally formed of a resin material.

  The size of the base member 2510 in the horizontal direction (the left-right direction in FIG. 11A) is set to be larger in the front view than the above-described recessed portion 2060c. Accordingly, the base member 2510 is arranged on the front side (the right side in FIG. 11B) of the recessed portion 2060c, and both ends of the base member 2510 in the horizontal direction are brought into contact with the front surface (front surface) of the base plate 60. it can.

  The base member 2510 has an opening 311 that is recessed downward from the upper end (the upper end in FIG. 11A), and a sheet thickness direction (in the vertical direction in FIG. 11B). 11 (b) (left and right directions)). The opening 311 in the second embodiment is formed so as to be continuous with the outer edge of the base member 2510. Further, the through holes 313 are formed at two places.

  Next, assembling of the winning opening unit 2300 to the base plate 60 will be described with reference to FIGS. FIG. 14A and FIG. 15A are front views of the game board 13. FIG. 14B is a cross-sectional view of the game board 13 taken along line XIVb-XIVb in FIG. 14A, and FIG. 15B is a cross-section of the game board 13 taken along line XVb-XVb in FIG. FIG. FIG. 14C is a cross-sectional view of the game board 13 along the line XIVc-XIVc in FIG. 14A, and FIG. 15C is a cross-section of the game board 13 along the line XVc-XVc in FIG. FIG.

  14A to 14C show a state in which the first winning member 2400 is provided on the base plate 60 (a state before the first winning member 2500 is provided). 15 (a) to FIG. 15 (c), a state where the winning opening unit 2300 is assembled to the base plate 60 is shown.

  As shown in FIG. 14, in assembling the winning opening unit 2300 to the base plate 60, first, the first winning member 2400 before driving the gaming nail YK is attached to the base plate 60. In this case, by inserting the first winning member 2400 along the concave portion 2060d of the base plate 60, as described above, the circular projection 2060d1 of the base plate 60 is formed inside the enlarged diameter portion 2413a formed in the through hole 2413. Is inserted.

  With the circular projection 2060d1 inserted inside the enlarged diameter portion 2413a, the tip of the countersunk screw is inserted into the through hole 2413 from the front side, and the tip of the countersunk screw is inserted into the inner peripheral surface of the circular projection 2060d1. Screw together. Thus, the first winning member 2400 before the driving of the gaming nail YK is attached to the base plate 60. In addition, the front surface of the first winning member 2400 is set to a position substantially the same as the front surface of the base plate 60.

  The game nail YK is driven into the first winning member 2400 from the front side in a state where the first winning member 2400 is fastened and fixed to the base plate 60. Thereby, it is easy to drive the gaming nail YK into the first winning member 2400 formed relatively small. Further, the relative position with the nail driven into the base plate 60 can be adjusted.

  Next, as shown in FIG. 15, the second winning member 2500 is attached to the front side. As a result, the distance between the first winning port 64 and the game nail can be reduced. That is, in a state where the first winning opening 64 (ball winning member 320) is formed in the first winning member 2400 into which the gaming nail YK is driven, a machine for driving the gaming nail YK when driving the gaming nail and the first winning opening 64 are used. It is necessary to separate the game nail YK from the first winning port 64 by a predetermined distance in order to avoid interference with the first winning port 64. The first winning port 64 is different from the first winning member 2400 into which the game nail YK is driven. Since the second prize member 2500 is formed in a later process than the first prize member 2400, the first prize port 64 is arranged closer to the game nail YK after the game nail YK is driven into the first prize member 2400. Can be set up.

  Next, a third embodiment will be described with reference to FIGS. In the second embodiment, a screw to be fastened when the first winning member 2400 is replaced with a new member is screwed into the same screw hole (female screw formed on the annular projection 2060d1) before and after replacement. Although the case has been described, in the third embodiment, when the first winning member 3400 is replaced, the screws for fastening the first winning member 3400 are different between before and after the replacement with different screw holes (in different annular projections 2060d1). Female screw). The same parts as those in the above-described embodiments are denoted by the same reference numerals, and description thereof will be omitted.

  FIG. 16A is a front view of the game board 13 in the third embodiment, and FIG. 16B is a cross-sectional view of the game board 13 along the line XVIb-XVIb in FIG. 16A. FIG. 17 is a perspective front view of the game board 13, and FIG. 18 is an exploded perspective front view of the game board 13. FIG. 18 shows a state in which the center frame 86 has been removed. 16 to 17, the external shapes of the winning opening unit 3300 and the base plate 60 are illustrated in a simplified manner.

  As shown in FIGS. 16 to 18, the winning opening unit 3300 in the third embodiment has a part (first winning member 3400) inserted into the inside of the recessed portion 2060 c and a front side of the base plate 60. (See FIG. 16 (a) on the front side of the drawing) and fixed with a tapping screw or the like.

  Around the center opening (center frame 86) side of the recessed portion 2060c, from the front side (front side in FIG. 16A) of the base plate 60 toward the rear side (back side in FIG. 16 (a)). A recess 3060d to be recessed is formed. The recess 3060d is formed so that the outer shape in a front view is substantially the same as the outer shape of a first winning member 3400 described later. Thereby, the first winning member 3400 can be disposed inside the recessed portion 3060d.

  Further, the recess 3060d is formed in an annular shape and has an annular protrusion 2060d1 protruding toward the front side, and a chamfered portion 3060d6 and an annular protrusion 2060d1 formed on the left and right edges on the front side. The inclined surface 3060d2 is inclined from the lower part of the plane (FIG. 16 (b)) to the upper part (FIG. 16 (b)) to the rear side (the left side in FIG. 16 (b)). Note that the inclined surface 3060d2 is formed to be inclined 5 degrees toward the back side from the lower side to the upper side.

  The annular projection 2060d1 has two sets formed at two locations in such a manner that the recessed portion 2060c is sandwiched between the same height in the horizontal direction (left and right directions in FIG. 16A). The screw holes (female screws) are formed at two positions (in the vertical direction) (i.e., two sets of four positions in total).

  The chamfered portion 3060d6 is formed by cutting out the front (front side in FIG. 16) edges of the left and right sides (the left and right sides in FIG. 16A) where the first winning member 3400 is disposed. The chamfered portion 3060d1 is formed so as to be inclined rearward toward the center in the left-right direction, and has a cut-out area from a lower portion (FIG. 16A) to an upper portion (FIG. 16A). Be enlarged. Further, the chamfered portion 3060d6 is formed such that the left and right inner ends are inclined 5 degrees upward on the back side with respect to the front surface of the base plate 60. That is, the cutout is formed at substantially the same angle as the inclined surface 3060d2.

  The winning opening unit 3300 includes a first winning member 3400 provided inside the concave portion 2060c of the base plate 60, and a second winning member provided on the front side of the first winning member 3400 and the base plate 60. 3500.

  The first winning member 3400 includes a main body 3410 formed from a substantially rectangular plate-like body that is horizontally long in front view, a swelling portion and 2420 swelling from the back side of the main body portion 3410, and a game nail driven from the front side. YK is mainly formed. In addition, the first winning member 3400 is disposed such that the short direction of a main body portion 3410 described later is parallel to the tilt direction of the above-described inclined surface 3060d2. Therefore, when the first winning member 3400 is disposed on the base plate 60, the first winning member 3400 is disposed so as to be inclined rearward with respect to the plane of the base plate 60.

  The main body part 3410 is provided with two through holes 3413 penetrating in a circular cross section in the plate thickness direction, and is concavely formed in a circular cross section from the back side (the left side in FIG. 16B) to the front side (the right side in FIG. 16B). And two concave portions 3414 to be formed. The concave portion 3414 is set to have the same shape as the enlarged diameter portion 3413a of the through hole 3413 described later (the concave size and the inner diameter are substantially the same). Further, the gaming nail YK is driven at a position in the lateral direction of the main body 3410 at an intermediate position between the axis of the through hole 3413 and the axis of the recess 3514. That is, a distance dimension L1 from the axis of the through hole 3413 to the axis of the game nail YK (see FIG. 16B) and a distance dimension L2 from the axis of the recess 3414 to the axis of the game nail YK (see FIG. 16B). ) Are set to the same distance.

  The through hole 3413 is a hole into which the tip of the screw is inserted when the first winning member 3400 is fastened to the base plate 60. The diameter of the through hole 3413 is increased toward the front side (the right side in FIG. 16B). Accordingly, when a countersunk screw is inserted into the through hole 3413 from the front side of the first winning member 3410, the head of the screw can be inserted into the through hole 2413.

  Further, the through hole 3413 includes an enlarged diameter portion 3413a whose diameter is enlarged on the back side (left side in FIG. 16B) from the substantially middle position in the plate thickness direction. The enlarged diameter portion 3413a is formed to have an inner diameter larger than the outer diameter of the annular projection 2060d1, and has a recess dimension in the plate thickness direction smaller than the projection dimension of the annular projection 2060d1.

  When the first winning member 3400 is disposed on the base plate 60, the through-holes 3413 are formed in two circles formed above (the upper part in FIG. 16B) out of the four annular protrusions 2060d1 described above. It is formed at a position facing the ring projection 2060d1. On the other hand, a concave portion 3414 is formed at a position facing the two annular projections 2060d1 formed below (the lower part in FIG. 16B) among the four annular projections 2060d1.

  Therefore, when the first winning member 3400 is provided inside the recessed portion 2360d, two annular protrusions 2060d1 disposed above the four annular protrusions 2060d1 are provided inside the enlarged diameter portion 3413a. Can be inserted, and the annular projection 2060d1 can be in contact with the inside of the enlarged diameter portion 3413a.

  Thereby, the two annular projections 2060d1 formed above among the four annular projections 2060d1 and the through holes formed in the first winning member 3400 can be fastened and fixed by the flathead screws. .

  In addition, when the first winning member 3400 is disposed inside the recessed portion 2360d, two annular projections 2060d1 disposed below the four annular projections 2060d1 inside the concave portion 3414 can be inserted. At the same time, the projecting distal end surface of the annular projection 2060d1 can abut on the concave bottom surface of the concave portion 3414.

  As described above, the through hole 3413 and the concave portion 3414 are formed at positions in the short direction of the first winning member 3400 that are separated by the same distance with respect to the gaming nail YK. Therefore, when the first winning member 3400 is detached from the base plate 60, the lower annular projection 2060 d 1 is inserted inside the enlarged diameter portion 3413 a of the through hole 3413 by turning the first winning member 3400 upside down. At the same time, the upper annular projection 2060d1 can be inserted inside the recess 3414. That is, by turning the first winning member 3400 upside down, the first winning member 3400 can be attached to the base plate 60. As described above, in the present embodiment, the first winning member 3400 can be attached to the base plate 60 in two different postures.

  Therefore, in the first winning member 3400 of the winning opening unit 3300, the gaming nail YK is implanted at the same position in the first posture and the second posture obtained by turning the first posture upside down. Even if the posture of the member 3400 is changed, the position of the game nail YK with respect to the base plate 60 can be maintained at a predetermined position.

  Further, as described above, the base plate 60 is formed with the chamfered portion 3060d6 cut out toward the front edge of the first winning member 3400 of the winning opening unit 3300. The front surface of the one winning member 3400 can be smoothly connected. That is, by forming the inclined surface 3060d2 on the base plate 60, it is possible to suppress a step from being formed between the front surface of the base plate 60 and the front surface of the first winning member 3400. Therefore, in order to suppress such a step, it is not necessary to arrange another member (for example, a part of the second winning member 2500) on the front of the base plate 60 or the front of the first winning member 3300.

  The second winning opening 3500 includes a base member 3510 formed of a horizontally long rectangular plate-like body as viewed from the front, a ball winning member 320 protrudingly formed on the front side (the right side in FIG. 16B) of the base member 4510, Formed mainly.

  The width of the base member 3510 in the longitudinal direction (the left-right direction in FIG. 16A) is formed larger than the width of the recessed portion 2060c in a front view. Accordingly, the base member 3510 can be disposed on the front side of the recessed portion 2060c, and both ends in the longitudinal direction of the base member 3510 can abut on the front surface of the base plate 60.

  The base member 3510 mainly includes an opening 311 penetratingly formed on the back side of the ball winning member 320 and through holes 313 penetrating both ends in the longitudinal direction (left and right directions in FIG. 19A).

  According to the winning opening unit 3300 configured as described above, when the gaming nail YK of the first winning member 3400 is broken or when the gaming nail YK falls off from the first winning member 3400, the second winning member 3500 is formed. Can be repaired by removing the defective first winning member 3400 and attaching a new (normal) first winning member 3400.

  Here, a gaming machine including a first gaming board member (base plate 60) and a second gaming board member fastened and fixed to the first gaming board member and forming a gaming board together with the first gaming board member is known. ing. An insertion hole (through hole 2413) is formed in the second game board member, and an internal thread (the inner edge portion of the annular projection 2060d1) is formed in the first game board member, and inserted into the insertion hole of the second game board member. The screw member (counterhead screw N2) is screwed into the female screw of the first game board member, whereby the second game board member is fastened and fixed to the second game board member. According to such a gaming machine, the second game board member can be attached to and detached from the first game board member. That is, when a failure or breakage occurs in the second game board member, only the second game board member is replaced, and the replacement of the entire game board can be unnecessary. However, in the conventional gaming machine described above, every time the second game board member is replaced, the screwing of the female screw and the screw member is repeated, and the thread of the female screw is set (abrasion or galling). However, if the number of replacements increases, the reliability of fastening and fixing decreases.

  On the other hand, according to the third embodiment, a plurality of (four in this embodiment) annular projections 2060d1 for fastening and fixing the first winning member 3400 of the winning opening unit 3300 to the base plate 60 are provided. In the first winning member 3400 of 3300, a plurality of (two in this embodiment) through holes 2413 through which the countersunk screw N2 can be inserted are formed, and the number is smaller than the number of annular projections 2060d1 (two in this embodiment). ), The first winning member 3400 is fastened and fixed to the base plate 60 by the countersunk screw N2. Therefore, when the thread of one female screw is set (abrasion or galling), another annular projection 2060d1 is formed. Can be used. Therefore, even when the number of replacements of the first winning member 3300 increases, the reliability of fastening and fixing can be ensured.

  Further, in the third embodiment, the first winning member 3400 of the winning opening unit 3300 is formed so as to be able to select at least a first posture with respect to the base plate 60 or a second posture obtained by inverting the first posture. In the first posture and the second posture, the inner edge of the annular projection 2060d1 connected to the through hole 2413 is the inner edge of the different annular projection 2060d1, so that the inner edge of the one annular projection 2060d1 has a thread. Is generated, the female screw of another annular projection 2060d1 can be used by changing the attitude of the first winning member 3400. Therefore, even when the number of replacements increases, the reliability of fastening and fixing can be ensured.

  For example, as shown in FIG. 16 to FIG. 18, when the first winning member 3400 is disposed on the base plate 60 with the through hole 2413 positioned above the first winning member 3400, the first winning member 3400 Countersunk screws N2 for fastening 3400 to base plate 60 are screwed into two annular projections 2060d1 formed above base plate 60. When the first winning member 3400 has a defect and is to be replaced, the through-hole 2413 of the first winning member 3400 after replacement is disposed on the base plate 60 in a state positioned below the first winning member 3400. Thus, the countersunk screw N2 for fastening the first winning member 3400 to the base plate 60 is screwed into the two annular projections 2060d1 formed below the base plate 60.

  Further, the first winning member 3400 has a smaller number of through holes 2413 than the number of annular projections 2060d1, so that the first winning member 3400 can be visually arranged on the front of the base plate 60. In this case, the number of through holes 3400 that can be visually recognized by the player in a state where the countersunk screw N2 is not inserted can be reduced. Therefore, the area of another member (for example, the second winning member 3500) for covering the through hole 3400 can be suppressed. It is preferable that the first winning member 3300 is fastened and fixed to the base plate 60 by the base plate 60 by the same number of countersunk screws N2 as the number of the through holes 3400. In this case, it is possible to eliminate the through hole 2413 that is visually recognized by the player in a state where the flathead screw N2 is not inserted. Therefore, it is not necessary to cover the through hole 3400 with another member.

  In addition, by reducing the number of through holes 2413, the strength of the first winning member 3400 can be ensured accordingly. Here, since the first winning member 3400 is relatively small, it is difficult to secure its strength. On the other hand, in the case where the first winning member 3400 is formed assuming that the game nail YK is to be implanted, when the game nail is implanted, or when the game ball is played during the game, It is necessary to secure the strength against the impact at the time of collision. Therefore, in the first winning member 3400 in which the game nail YK is implanted, it is particularly effective to reduce the number of the through holes 2412 from the viewpoint of securing strength.

  In addition, the base plate 60 is provided with a predetermined inclination angle (5 degrees in the present embodiment) on the inclined surface 3060d2 that supports the first winning member 3400 of the winning opening unit 3300, and the first winning member 3400 has an inclination. Since the nail is implanted perpendicularly to the main body 3410 supported by the surface 3060d2, even if the posture (the first posture or the second posture) of the first winning member 3400 is changed, the nail is placed on the base plate 60. The inclination angle can be kept constant.

  Next, a fourth embodiment will be described with reference to FIGS. In the second embodiment, the case where the screw to be fastened when the first winning member 2400 is replaced is screwed into the same female screw portion (annular projection 2060d1) before and after the replacement is described. In the embodiment, when the first winning member 3400 is replaced, a screw for fastening the first winning member 3400 is screwed into a different female screw portion (annular protrusion 2061d1) before and after replacement.

In the second embodiment, the case where the countersunk screw N2 for fastening the first winning member 2400 is inserted from the front side of the game board 13 has been described, but in the sixth embodiment, the countersunk screw N2 is inserted from above. . The same parts as those in the above-described embodiments are denoted by the same reference numerals, and description thereof will be omitted.

  FIG. 23A is a front view of the game board 13 in the sixth embodiment, and FIG. 23B is a cross-sectional view of the game board 13 taken along line XXIIIb-XXIIIb in FIG. FIG. 24 is an exploded perspective front view of the game board 13. 23 (a) and 23 (b) show a state in which the second winning member 2500 has been removed, and FIG. 24 shows a state in which the center frame 86 has been removed. 23 and 24, the external shapes of the winning opening unit 6300 and the base plate 60 are simplified and shown.

  As shown in FIG. 23 and FIG. 24, the base plate 60 in the sixth embodiment is arranged such that the recessed portion 2060c is positioned from the front side (front side in FIG. 23A) toward the center opening (center frame 86) side. A recess 6060d that is recessed toward the side is formed.

  The outer shape of the recessed portion 6060d in a front view is substantially the same as the outer shape of the first winning member 2400. Thus, the first winning member 6400 can be inserted and disposed inside the recess 6060d. Further, a plurality of fastening holes 6060d4 that are recessed downward are formed on the lower surface where the recess 6060d is formed.

  The fastening hole 6060d4 is formed in a circular shape when viewed from above, and is formed coaxially with the axis of the through hole 6413 of the first winning member 6400 in a state where the first winning member 6400 is provided on the base plate 60.

  The winning opening unit 6300 includes a first winning member 6400 provided inside the recessed portion 2060c of the base plate 60, and a second winning member provided on the front side of the first winning member 6400 and the base plate 60. 2500.

  The first winning member 6400 includes a main body portion 6410 formed from a rectangular plate-like body that is horizontally long in front view, a bulging portion 2420 bulging from the back side of the main body portion 6410, and a gaming nail YK driven from the front side. Formed from

  The main body portion 6410 and the bulging portion 2420 are formed with a plurality of through holes 6413 that penetrate vertically (FIG. 23A, vertical direction). The through hole 6413 is a hole for inserting a screw N4 for fastening the first winning member 5400, and is formed to be larger than the outer diameter of the tip of the screw N4. In addition, the diameter of the through hole 6413 is enlarged at the upper end so that the head of the screw N4 can be inserted. Thus, when the first winning member 5400 is fastened, it is possible to suppress the head of the screw N4 from projecting upward (the center frame 86).

  The through-holes 6413 are formed at both ends in the longitudinal direction (the left-right direction in FIG. 23A) of the first winning member 6400 (three in total). As described above, the through hole 6413 of the first winning member 6400 is formed coaxially with the fastening hole 6060d4 of the base plate 60. Therefore, the first winning member 6400 is fastened and fixed to the base plate 60 by inserting the screw N4 into the through hole 6413 and screwing it into the fastening hole 6060d4.

  According to the winning opening unit 6300 configured as described above, the center frame 86 is used as a base when the gaming nail YK of the first winning member 6400 is broken or when the gaming nail YK falls off from the first winning member 6400. After removal from the plate 60, the defective first winning member 540 can be removed and repaired by installing a new (normal) first winning member 6400.

  As described above, the through holes 6413 are formed at a plurality of locations (six locations) in the first winning member 6400. Therefore, when replacing the first winning member 6400, after disposing the first winning member 6400 after replacement on the base plate 60, it is coaxial with the fastening hole 6060d4 in which the screw N4 has never been screwed. The screw N4 is inserted into the located through hole 6413, and the screw N4 is screwed into the fastening hole 6060d4. Thus, the female screw for fastening the screw N4 can be made different before and after the replacement of the first winning member 6400.

  Accordingly, the female screw (fastening hole 6060d4) to which the screw N4 is screwed can be changed with the replacement of the first winning member 6400, so that the female screw can be prevented from being slackened. As a result, it is possible to prevent the screw N4 screwed to the base plate 60 from being removed due to an impact or the like.

  Further, since the through-hole 6413 and the fastening hole 6060d4 extend substantially parallel to the front surface of the base plate 60, the through-hole 6413 or the head of the screw N4 can be prevented from being exposed to the front surface (game surface) of the game board 13. Therefore, the through hole 6413 through which the screw N4 is not inserted can be hardly visually recognized by the player, and the area of another member for covering the through hole 6413 can be suppressed or eliminated. Further, since the head of the screw N4 is not exposed to the rolling surface (game surface) of the game ball, it is not necessary to use the flat head screw for the screw N4 or to provide a counterbore (recess) for accommodating the head of the screw N4. And the structure can be simplified.

  Next, a seventh embodiment will be described with reference to FIGS. In the second embodiment, the case where the countersunk screw N2 is screwed into the annular projection 2060d1 formed on the base plate 60 has been described. However, in the seventh embodiment, a screwed portion (circle) with which the countersunk screw N2 is screwed. An annular projection 2060d1) is formed on the first winning member 7400. The same parts as those in the above-described embodiments are denoted by the same reference numerals, and description thereof will be omitted.

  FIG. 25 (a) is a front view of the game board 13 in the seventh embodiment, and FIG. 25 (b) is a cross-sectional view of the game board 13 along the line XXVb-XXVb in FIG. 25 (a). FIG. 26 is an exploded perspective front view of the game board 13. FIG. 26 shows a state in which the center frame 86 has been removed. 25 and 26, the outer shapes of the winning opening unit 7300 and the base plate 60 are simplified and shown. Further, in FIGS. 25 (a) and 25 (b), the first winning member 2500 of the winning opening unit 7300 is seen transparently, and its outer shape is shown by a chain line.

  As shown in FIGS. 25 and 26, the base plate 60 according to the seventh embodiment is arranged such that the recessed portion 2060c has a central opening (center frame 86) side from the rear side (the back side in FIG. 25A). A recess 7060d is formed on the side (the front side in FIG. 25A), and a game board overhang 7060k is formed on a non-recessed portion on the front side of the recess 7060d.

  The outer shape of the recess 7060d in a rear view is formed to be substantially the same as the outer shape of the first winning member 7400. Thus, the first winning member 7400 can be inserted and disposed inside the recess 7060d. In the recess 7060d, a plurality of through holes 7060e penetrating to the front side are formed.

  The through hole 7060e is formed in a circular shape when viewed from the front, and is formed coaxially with the axis of the annular projection 7414 of the first winning member 7400 when the first winning member 7400 is provided on the base plate 60. . The through hole 7060e is formed so that the front side has an enlarged diameter to accommodate the head of the countersunk screw N2, and the back side has an enlarged diameter to accommodate the annular projection 7414. That is, the enlarged diameter portion 7060e includes an enlarged diameter portion 7060e1 on the back side.

  The enlarged diameter portion 7060e1 is formed to be larger than the outer diameter of an annular protrusion 7414 described later, and is formed to have a recessed size on the front side smaller than the projected size of the annular protrusion 7414 described later. Accordingly, in a state where the first winning member 7400 is arranged on the base plate 60, the annular projection 7414 can be inserted inside the enlarged diameter portion 7060e1, and the protruding distal end surface of the annular projection 7414 can be inserted into the enlarged diameter portion 7060e1. It can be brought into contact with the concave bottom surface.

  That is, in a state where the first winning member 7400 is fastened and fixed to the base plate 60, a state in which a gap is formed between the back surface of the first winning member 7400 and the front surface of the base plate 60 can be formed. Therefore, the first winning section 7400 can be easily displaced relative to the base plate 60 by utilizing the elastic deformation of the annular projection 7414. As a result, for example, when the game nail YK is implanted in the first winning member 7400, the vibration when the game ball collides with the game nail YK during the game is absorbed, and the game nail YK is damaged (broken). ) Can be suppressed.

  In this case, it is preferable that the annular protrusion 7414 is set to a size smaller than the inner size of the enlarged diameter portion 7060e1. It is preferable that the first winning member 7400 and the base plate 60 do not abut on other portions except for the protruding tip of the annular protrusion 7414 and the concave bottom surface of the enlarged diameter portion 7060e1. Thus, the annular protrusion 7414 can be more easily elastically deformed.

  The winning opening unit 7300 includes a first winning member 7400 provided inside the concave portion 2060c of the base plate 60, and a second winning member provided on the front side of the first winning member 7400 and the base plate 60. 2500.

  The first winning member 7400 includes a main body 7410 formed of a horizontally long rectangular plate-like body in front view, a bulging portion 7420 bulging from the front side of the main body 7410, and a bulging portion 7420 side (front side). ) Is mainly provided with game nails YK driven from the above.

  The bulging portion 7420 is formed at a substantially central position in the longitudinal direction (the left-right direction in FIG. 25A) of the main body 7410 and is shorter than the main body 7410 in the longitudinal direction of the main body 7410. As a result, on the outer side in the longitudinal direction of the main body portion 7410, a main body side overhang portion 7437 that protrudes outside the bulging portion 7420 is formed. An annular projection 7414 is formed on the main body-side bulging portion 7437 of the main body 7410 so as to protrude in an annular shape on the base plate 60 side on the front side.

  Two annular projections 7414 are formed on both ends in the longitudinal direction of the main body 7410 (a total of four annular projections are formed). The annular projection 7414 is a portion to which the countersunk screw N2 is screwed, and a female screw is formed in an annular inner peripheral portion.

  The four countersunk screws N2 for fastening the first winning member 7400 are inserted through the through holes 7060e of the base plate 60 and screwed into the annular projections 7414 of the first winning member 7400. Thereby, the first winning member 7400 can be fastened and fixed to the base plate 60.

  According to the winning unit 7300 configured as described above, when the gaming nail YK of the first winning member 7400 is broken or when the gaming nail YK falls off the first winning member 7400, the second winning member 7500 is removed. After being removed from the base plate 70, the defective first winning member 7400 can be removed and a new (normal) first winning member 7400 can be attached for repair.

  Here, a first game board member (base plate 60) and a second game board member (winning winning unit 3300) fastened and fixed to the first game board member to form a game board together with the first game board member are provided. Gaming machines are known. An insertion hole (through hole 2413) is formed in the second game board member, and an internal thread (the inner edge portion of the annular projection 2060d1) is formed in the first game board member, and inserted into the insertion hole of the second game board member. The screw member (counterhead screw N2) is screwed into the female screw of the first game board member, whereby the second game board member is fastened and fixed to the first game board member. According to such a gaming machine, the second game board member can be attached to and detached from the first game board member. That is, when a failure or breakage occurs in the second game board member, only the second game board member is replaced, and the replacement of the entire game board can be unnecessary. However, in the conventional gaming machine described above, every time the second game board member is replaced, the screwing of the female screw and the screw member is repeated, and the thread of the female screw is set (abrasion or galling). However, if the number of replacements increases, the reliability of fastening and fixing decreases.

  On the other hand, according to the seventh embodiment, the through hole 7060e into which the flathead screw N2 is inserted is formed in the base plate 60, and the flathead screw N2 inserted through the through hole 7060e of the base plate 60 is screwed. Since the female screw (annular projection 7414) is formed on the first winning member 7400, a new female screw can be used when the first winning member 7400 is replaced. Therefore, even when the number of replacements increases, the reliability of fastening and fixing can be ensured.

  Also, an annular projection 7414 protruding from the front surface of the first winning member 7400, and an enlarged diameter portion 7060e1 recessed on the rear surface of the base plate 60 so as to receive the annular projection 7414 are provided. Since the through hole 7060e is formed so as to communicate with the enlarged diameter portion 7060e1 of the base plate 60, the length of the screw portion (shaft portion) of the female screw can be secured. . Therefore, the axial force of the countersunk screw N2 can be increased accordingly, and the first winning member 7400 can be easily firmly fixed and fixed to the base plate 60.

  Since the first member 7400 is relatively small in size, it is difficult to secure its strength. However, by forming a female screw on the annular projection 7141 and securing the length of the screw portion, the flat head screw N2 is formed. The load on the first winning member 7400 can be dispersed while a predetermined axial force can be applied to the first winning member 7400. That is, the configuration in which the female screw is provided on the annular protrusion 7141 is particularly effective from the viewpoint of achieving both strong fastening and preventing damage to the constituent members.

  In addition, since the first winning member 7400 has the recess 7060d recessed from the rear side to the front side, it is possible to prevent the base plate 60 from being damaged when the game nail YK is driven.

  That is, in the above-described second embodiment, since the depression 2060d is recessed from the front side to the back side, the impact when the gaming nail YK is driven into the first winning member 2400 is reduced. Is transmitted to the base plate 60 at the back side portion (the portion thinned by the recess portion 2060d) of the recess portion 2060d. Accordingly, a force acts on the thinned portion of the base plate 60 in a direction away from the recessed portion 2060d (backward direction). As a result, the force concentrates on the corners of the recess 2060d, and the base plate 60 may be damaged.

  On the other hand, in the seventh embodiment, the impact when the game nail YK is driven is transmitted from the countersunk screw N2 to the base plate 60 in the front side portion (the portion thinned by the recess 2060d) of the recess 7060d. You. Therefore, a force acts on the thinned portion of the base plate 60 in a direction approaching the concave portion 7060d side. As a result, it is possible to suppress the concentration of the force on the corners of the recess 7060d, and to prevent the base plate 60 from being damaged.

  Further, a central opening (window portion) for making the third symbol display device 81 visible and a concave portion 2060c for disposing the first winning member 7400 are formed in the base plate 60, Since the central opening and the recessed portion 2060c communicate with each other, when replacing the first winning member 7400, the operator uses the central opening of the base plate 60 to grip (grasp) the first winning member 7400. ). Therefore, the workability of the replacement work of the first winning member 7400 can be improved. For example, when the game nail YK is implanted in the first winning member 7400, the replacement work can be performed without gripping the game nail YK, so that the game nail YK of the newly installed first winning member 7400 is gripped. It can be suppressed that the game nail is bent or the interval between the game nails YK is changed by suppressing the holding.

  Also, two game nails YK are implanted in the first winning member 7400, and a female screw is not formed on an extension of an imaginary line connecting the two game nails YK. Cracks can be suppressed. That is, since the strain (elastic deformation of the first winning member 7400) due to the implantation of the two game nails YK overlaps in the direction of the virtual line connecting the two game nails YK, in the region on the extension of the virtual line, Where the first winning member 7400 is apt to crack, the female screw is not formed in such a region, so that the strain caused by the installation of the game nail YK and the load caused by the screwing of the countersunk screw N2 are further applied. The overlapping can be suppressed. As a result, cracking of the first winning member 7400 can be suppressed.

  The distance between the extension of the imaginary line and the female screw may be set to be equal to or larger than the reference dimension (nominal diameter of the screw) of the outer diameter of the countersunk screw N2 from the viewpoint of suppressing cracking of the first winning member 7400. More preferably, it is more preferably set to be at least twice the reference dimension of the outer diameter of the flathead screw N2.

  Next, an eighth embodiment will be described with reference to FIG. In the second embodiment, the case where the first winning member 2400 is formed to be detachable from the front side with respect to the base plate 60 has been described. However, in the eighth embodiment, the first winning member 8400 is attached to the base plate 60. And is formed so as to be removable from above. The same parts as those in the above-described embodiments are denoted by the same reference numerals, and description thereof will be omitted.

  FIG. 27A is a cross-sectional view of the game board 13 in the eighth embodiment. Note that FIG. 27A corresponds to the cross-sectional view of FIG. Also, in FIG. 27A, the external shapes of the winning opening unit 8300 and the base plate 60 are simplified and shown. Further, in FIG. 27A, the second winning member 2500 of the winning opening unit 8300 is seen transparently, and its outer shape is shown by a broken line.

  As shown in FIG. 27 (a), the base plate 60 in the eighth embodiment is formed at a recess 7060d recessed toward the front side on the back surface of the base plate 60, and at the opposite side of the recess 7060d. The second recess 8060f (which is recessed toward the rear side on the front surface of the base plate 60), the protrusion 8060g formed between the recess 7060d and the second recess 8060f, and the base from the recess 7060d A through hole 7060e formed through the front surface of the plate 60 is mainly provided.

  The second recess 8060f is formed so as to be continuous with the recess 2060c, and the distance dimension in the left-right direction (the left-right direction in FIG. 27A) is smaller than the left-right dimension of the recess 7060d. The through-hole 7060e is formed on the front side where the recess 7060d is formed, and is positioned outside the second recess 8060f in the left-right direction.

  The protruding portion 8060g is a plate that is inserted into a groove portion 8414 of a first winning member 8400 described later, and has substantially the same dimension as the up-down direction (the direction from the near side of the drawing to the far side of the drawing) of the recess 7060d. They are formed in the same vertical dimension.

  The winning opening unit 7300 includes a first winning member 8400 provided inside the concave portion 2060c of the base plate 60, and a second winning member provided on the front side of the first winning member 8400 and the base plate 60. 3500.

  The first winning member 8400 includes a main body 8410 formed of a rectangular plate-like body that is horizontally long in front view, a bulge 8420 bulging from the front side of the main body 8410, and a bulge 8420 side (front side). ) Is mainly provided with game nails YK driven from the above.

  The bulging portion 8420 is formed at a substantially central position in the longitudinal direction of the main body portion 8410 (the left-right direction in FIG. 27A), and is shorter than the main body portion 8410 in the longitudinal direction of the main body portion 8410. Further, a groove portion 8421 is formed (recessed) from the side surface in the left-right direction (the left-right direction in FIG. 27A) on the side of the connection portion with the main body portion 8410 in the bulging portion 8420.

  A female screw (fastening hole 8415) into which the flathead screw N2 can be screwed is formed on the main body portion 8410 outside the bulging portion 8420 in the longitudinal direction. The fastening hole 8415 is formed coaxially with the through hole 7060e of the base plate 60 in a state where the first winning member 8400 is disposed on the base plate 60. Therefore, the first winning member 8400 is fastened and fixed to the base plate 60 by inserting the countersunk screw N2 into the through hole 7060e and screwing it into the fastening hole 8415.

  The groove portion 8421 is formed in the entire area in the short direction of the main body portion 8410 (the direction connecting the near side in FIG. 27A and the far side in FIG. 27A). Also, the groove 8421 is formed so that the distance between the opposing sides in the front-rear direction (the vertical direction in FIG. 27A) is larger than the front-rear dimension of the above-described protrusion 8060g, and the recess dimension in the left-right direction is the protrusion 8060g. Is formed so as to be larger than the protrusion dimension.

  As a result, the first winning member 8400 is displaced from above (the near side in FIG. 27 (a) paper) to below (in the back side in FIG. 27 (a) paper) the concave portion 2060c, and at the same time, protrudes inside the groove 8421. 8060 g can be inserted and arranged on the base plate 60. That is, the projection 8060g and the groove 8421 are engaged.

  According to the winning opening unit 8300 configured as described above, the center frame 86 is used as a base when the gaming nail YK of the first winning member 8400 is broken or when the gaming nail YK falls off from the first winning member 8400. After removal from the plate 60, the defective first winning member 8400 can be removed and repaired by installing a new (normal) first winning member 8400.

  As described above, the fastening hole 8415 for fastening the first winning member 8400 to the base plate 60 is formed in the first winning member 8400. Therefore, when the first winning member 8400 is replaced, the fastening hole 8415 for fastening the first winning member 8400 is also replaced, so that each time the first winning member 8400 is replaced, the female screw portion is worn. It is possible to suppress dripping. As a result, it is possible to prevent the countersunk screw N2 to be fastened to the fastening hole 8415 of the first winning member 8400 from being removed (loose) by an impact or the like.

  In the eighth embodiment, as described above, the protrusion 8060g protruding from the inner surface of the recess 2060c of the base plate 60, and the protrusion 8060g is recessed on the outer surface of the first winning member 8400 so as to accept the protrusion 8060g. And a groove 8421 extending continuously along a direction parallel to the front surface (game surface) of the base plate 60 and connected to the central opening (window portion). The first winning member 8400 can be prevented from falling off from the base plate 60 even when the flathead screw N2 is loosened or removed due to vibrations caused by the game or due to improper means, while allowing the player to remove the first winning member 8400 from the central opening side. .

  That is, since the projection 8060g and the groove 8421 are engaged with each other, if the flathead screw N2 comes out of the fastening hole 8415 due to an impact or the like, the engagement between the projection 8060g and the groove 8421 causes the first. The movement of the winning member 8400 in the front-rear direction with respect to the base plate 60 can be suppressed.

  Further, a game board overhanging portion 7060k in which an insertion hole 7060e is formed to protrude from the inner surface of the recessed portion 2060c of the base plate 60, and a main body side overhang in which a female screw is formed to protrude from the outer surface of the first winning member 8400. A projection 8060g is projected from the game board overhanging portion 7060k of the base plate 60, and the main body side overhanging portion 7437 of the first winning member 8400 is not formed (the outer surface of the bulging portion 8420). Since the groove portion 8421 is recessed in (1), the length of the screw portion (completely threaded portion) of the female screw can be secured. Accordingly, the axial force of the countersunk screw N2 can be increased accordingly, and the first winning member 8400 can be easily firmly fixed and fixed to the base plate 60.

  Since the first winning member 8400 is relatively small in size, it is difficult to secure the strength. However, the projecting portion 8060g projects from the game board overhanging portion 7060k of the base plate 60 to reduce the length of the screw portion. By securing, the load on the first winning member 8400 can be dispersed while a predetermined axial force can be applied to the flathead screw N2. That is, the configuration in which the projecting portion 8060g is projected from the game board overhanging portion 7060g of the base plate 60 is particularly effective from the viewpoint of achieving both firm fastening and prevention of damage to the first winning member 8400.

  Next, a ninth embodiment will be described with reference to FIG. In the second embodiment, the case where the first winning member 2400 is formed to be detachable from the front side with respect to the base plate 60 has been described. However, in the ninth embodiment, the first winning member 9400 is attached to the base plate 60. It is formed so as to be removable from the upper side. The same parts as those in the above-described embodiments are denoted by the same reference numerals, and description thereof will be omitted.

  FIG. 27B is a sectional view of the game board 13 in the ninth embodiment. Note that FIG. 27B corresponds to the cross-sectional view of FIG. Also, in FIG. 27B, the external shapes of the winning opening unit 8300 and the base plate 60 are simplified and shown. Further, in FIG. 27B, the second winning member 2500 of the winning opening unit 8300 is shown in a transparent view, and the outline thereof is shown by a broken line.

  As shown in FIG. 27B, the base plate 60 in the ninth embodiment has a recessed portion that is recessed from the rear side (the upper side in FIG. 27B) to the front side (the lower side in FIG. 27B). 9060d. In the recess 9060d, a protrusion 9060g is formed to protrude inward from the inner wall at the rear end of the base plate 60.

  The protruding portion 9060g is a wall portion for forming a facing surface between the back surface of the recess portion 9060d and the protruding portion 9060g, and is formed at a predetermined interval from the back surface of the recess portion 9060d. As a result, an engaging portion 9417 of the first winning member 9400 described later can be inserted between the back surface of the concave portion 9060d and the facing portion of the projecting portion 9060g.

  In the protruding portion 9060g, the protruding tip position in the width direction of the base plate 60 (the left-right direction in FIG. 27B) is set outside the through-hole 7060e in the width direction of the base plate 60. Thereby, the screwing distance between the countersunk screw N2 and the first winning member 8400 can be secured.

  The winning opening unit 9300 includes a first winning member 9400 provided inside the recessed portion 2060c of the base plate 60, and a second winning member provided on the front side of the first winning member 9400 and the base plate 60. 2500.

  The first winning member 9400 includes a main body portion 9410 formed from a horizontally long rectangular plate-like body in front view, a bulging portion 9420 bulging from the front side of the main body portion 9410, and a bulging portion 9420 side (front side). ) Is mainly provided with game nails YK driven from the above.

  The bulging portion 9420 is formed at a substantially central position in the longitudinal direction of the main body portion 9410 (the left-right direction in FIG. 27B), and is formed shorter than the main body portion 9410 in the longitudinal direction of the main body portion 9410. Further, a female screw (fastening hole 8415) to which the countersunk screw N2 can be screwed is formed on the outside of the main body portion 9410 in the longitudinal direction. The fastening hole 8415 is formed coaxially with the through hole 7060e of the base plate 60 in a state where the first winning member 9400 is arranged on the base plate 60. Therefore, the first winning member 9400 is fastened and fixed to the base plate 60 by inserting the countersunk screw N2 into the through hole 7060e and then screwing it into the fastening hole 8415.

  The main body portion 9410 is formed with a recessed portion 9416 that is recessed inward from both ends in the longitudinal direction (the left and right direction in FIG. 27B) on the back side (the upper side in FIG. An engaging portion 9417 that partially projects outward in the left-right direction is formed on the front side of the setting portion 9146.

  The concave portion 9416 is formed at the outer end in the left-right direction, and is formed in the entire vertical direction. Further, the recessed portion 9416 is set such that the recessed size in the left-right direction is set larger than the protrusion size in the left-right direction of the protrusion 9060g of the base plate 60, and the recessed size in the front-rear direction is set to The dimension is set larger than the longitudinal dimension of the portion 9060g. As a result, the first winning member 9400 is displaced downward from above the recessed portion 2060c (on the front side of the drawing in FIG. 27A), and the engaging portion 9417 is provided between the opposing portion of the projecting portion 9060g and the concave portion 9060d. Can be inserted and arranged. As a result, a state can be achieved in which the protruding portion 9060g and the concave portion 9060d are opposed to each other and the engaging portion 9417 is engaged.

  According to the winning opening unit 9300 configured as described above, when the gaming nail YK of the first winning member 9400 is broken or when the gaming nail YK falls off from the first winning member 9400, the center frame 86 is used as a base. After removal from the plate 60, the defective first winning member 9400 can be removed and repaired by attaching a new (normal) first winning member 9400.

  As described above, the fastening hole 8415 for fastening the first winning member 9400 to the base plate 60 is formed in the first winning member 9400. Therefore, when the first winning member 9400 is replaced, the fastening hole 8415 for fastening the first winning member 9400 is also replaced, so that the female screw portion is worn out every time the first winning member 9400 is replaced. It is possible to suppress dripping. As a result, it is possible to prevent the countersunk screw N2 fastened to the fastening hole 9415 of the first winning member 9400 from being removed (loose) by an impact or the like.

  Further, in the ninth embodiment, as described above, the engaging portion 9417 protruding from the outer surface of the first winning member 9400 and the inner peripheral portion of the recessed portion 2060c of the base plate 60 can receive the engaging portion 9417. And a depression 9060d extending continuously along a direction parallel to the front surface (game surface) of the base plate 60 and connected to the central opening, so that the first winning member 9400 can be attached to the base plate 60. The first winning member 9400 can be prevented from falling off from the base plate 60 even when the countersunk screw N2 is loosened or removed due to vibrations caused by the game or by improper means, while making it possible to remove the first winning member 9400 from the central opening side. .

  That is, since the projecting portion 9060g and the recessed portion 9060d are engaged with each other, if the countersunk screw N2 comes out of the fastening hole 8415 due to an impact or the like, the first winning member 8400 moves back and forth with respect to the base plate 60. The movement in the direction can be suppressed.

  A game board overhang 7060k in which a through hole 7060e is formed from the inner surface of the recessed portion 2060c of the base plate 60, and a main body side overhang 7437 in which a female screw is formed from the outer surface of the first winning member 9400. Since the engaging portion 9417 protrudes from the main body side overhanging portion 7437 of the first winning member 9400, and the recess 9060g is recessed at a portion of the base plate 60 where the game board overhanging portion 7060k is not formed. , The length of the threaded portion (completely threaded portion) of the female screw can be ensured. Accordingly, the axial force of the countersunk screw N2 can be increased accordingly, and the first winning member 9400 can be easily firmly fixed and fixed to the base plate 60.

  Since the first winning member 9400 is relatively small in size, it is difficult to secure its strength. However, the engaging portion 9417 protrudes from the main body side overhanging portion 7437 of the first winning member 9400 to form a screw portion. By ensuring the length, the load on the first winning member 9400 can be dispersed while a predetermined axial force can be applied to the flathead screw N2. That is, the configuration in which the engaging portion 9417 protrudes from the main body-side overhanging portion 7437 of the first winning member 9400 is particularly effective from the viewpoint of achieving both strong fastening and prevention of damage to the first winning member 9400.

  Next, a tenth embodiment will be described with reference to FIGS. In the second embodiment, the case where the left and right surfaces of the bulging portion 2420 of the first winning member 2400 are continuously extended in the up-down direction (that is, not protruded to the back side of the main body 2410) has been described. A protruding portion 10422 protruding outward in the left-right direction is formed on the bulging portion 10420 of the first winning member 10400 of the tenth embodiment. The same parts as those in the above-described embodiments are denoted by the same reference numerals, and description thereof will be omitted.

  FIG. 28A is a rear perspective view of the first winning member 10400 in the tenth embodiment, and FIG. 28B is an exploded perspective front view of the first winning member 10400 and the base plate 60. FIG. 29A is a front view of the game board 13, and FIG. 29B is a cross-sectional view of the game board 13 taken along line XXIXb-XXIXb in FIG. 28A and FIG. 28B, the outer shapes of the first winning member 10400 and the base plate 60 are illustrated in a simplified manner. FIGS. 29A and 29B show a state in which the second winning member 2500 has been removed.

  As shown in FIG. 28, the base plate 60 in the tenth embodiment has a concave portion 2060c that is recessed downward from below the center opening of the base plate 60, and a concave portion formed by being connected to the concave portion 2060c. And a notch 10060h formed by notch formation (opening formation) from the part of the recess 2060d to the back side.

  The notch 10060h is an opening for receiving a protruding portion 10422 formed on a first winning member 10400 described later. The notch 10060h is formed as an opening communicating with the recessed portion 2060c by forming a notch on the remaining portion of the base plate 60 where the recessed portion 2060d is formed toward the outside in the left-right direction (the left-right direction in FIG. 29A).

  The winning opening unit 10300 includes a first winning member 10400 disposed inside the recess 2060c of the base plate 60, and a second winning member 2500 (disposed on the front side of the first winning member 10400 and the base plate 60). FIG. 12).

  The first winning member 10400 includes a main body 2410 formed of a rectangular plate-like body that is horizontally long in front view, a bulge 2420 bulging from the back side of the main body 2410, and a bulge 2420 extending from the bulge 2420. The main part 2410 is formed mainly with a protruding portion 10422 protruding outward in the longitudinal direction (the left-right direction in FIG. 29A) and a game nail YK driven from the front surface of the main body 2410.

  The protruding portion 10422 extends from an intermediate portion obtained by equally dividing the bulging portion 2420 in the short direction of the main body portion 2410 (vertical direction in FIG. 29A) from the longitudinal direction of the main body portion 2410 (horizontal direction in FIG. 29A). It is protruded. The protruding portion 10422 is formed and set such that the outer side of the protruding tip (left and right ends) is substantially flush with both longitudinal end surfaces (outer peripheral surfaces) of the main body portion 2410, and is set from the main body portion 2410 side. It is formed along an extension of an imaginary line connecting the two game nails YK to be implanted.

  Further, the size of the bulging portion 10400 in the direction (vertical direction (vertical direction in FIG. 29B)) orthogonal to the virtual line connecting the two game nails YK is larger than the size of the protruding portion 10422. In addition, it is possible to increase the rigidity of the first winning member 10400 in a direction orthogonal to the virtual line connecting the two game nails YK, thereby suppressing the damage of the first winning member 10400.

  The through-holes 2413 formed in the main body 2410 are formed at upper, lower, left and right ends of the main body 2410 when viewed from the front, and two upper and lower portions are formed at positions sandwiching the projecting portion 10422. Accordingly, both a region for increasing the rigidity of the first winning member 10400 and a region for fastening and fixing the first winning member 10400 to the base plate 60 can be efficiently secured. As a result, it is possible to achieve both suppression of breakage of the first winning member 10400 and miniaturization of the first winning member 10400.

  The notch 10060h described above is formed in substantially the same shape as the outer shape of the protruding portion 10422 in a front view, and when the first winning member 10400 is arranged on the base plate 60, the protruding portion 10422 is notched. Part 10060h. This allows the base plate 60 to hold the projecting portion 10422. That is, the configuration of the first winning member 10400 can be enhanced by utilizing the rigidity of the base plate 60 by at least a part of the protruding portion 10422 being held. As a result, damage to the first winning member 10400 can be suppressed.

  The game nail YK is driven into the main body 2410 at an intermediate position in the short direction. Accordingly, since the protruding portion 10422 is formed along an extension of the virtual line connecting the two game nails YK implanted on the main body portion 2410 side, the damage of the first winning member 10400 can be suppressed. That is, since the strain (elastic deformation of the first winning member 10400) due to the vegetation of the two game nails YK overlaps in the direction of the virtual line connecting the two game nails, the first area in the extension of the virtual line is the first area. By forming the protruding portion 10422 in such a place where the winning member 10400 is apt to crack, it is possible to alleviate the distortion accompanying the implantation of the gaming nail YK. Therefore, it is possible to prevent the load associated with the collision of the game ball with the game nail YK from further overlapping with the strain associated with the implantation of the game nail YK.

  According to the winning opening unit 10300 configured as described above, when the gaming nail YK of the first winning member 10400 is broken or when the gaming nail YK falls off from the first winning member 10400, the first winning member 2500. Can be repaired by removing the defective first winning member 10400 and attaching a new (normal) first winning member 10400 after removing the first winning member 10400 from the base plate 60.

  Here, a first game board member (base plate 60) and a second game board member (first winning member 2400) removably disposed on the first game board member and forming a game board together with the first game board member. ), And a gaming machine in which a nail (gaming nail YK) is planted on a gaming surface of a second gaming board member is known. According to such a gaming machine, when the nail of the second gaming board member is broken, the replacement of the entire gaming board can be made unnecessary by replacing only the second gaming board member. However, in the conventional gaming machine described above, since the second game board member is formed relatively small, it is difficult to secure the rigidity of the second game board member. Therefore, when an external force is applied to the nail due to the collision of the game ball, there is a problem that the second game board member is easily damaged.

  On the other hand, in the tenth embodiment, since the first winning member 10400 is formed so as to be able to suppress the damage of the first winning member 10400 due to the action of the external force on the game nail YK, the external force is applied to the game nail YK by the collision of the game ball. In this case, the damage of the first winning member 10400 can be suppressed.

  That is, the first winning member 10400 has a bulged portion 2420 in which the game nail YK is implanted, and a main body side which has a smaller thickness than the bulged portion and is abutted and fixed to the base plate 60. The main body side overhanging portion 2437 is provided so as to protrude from the contact surface with the base plate 60 and has the protruding portion 10422 connected to the bulging portion 2420. The rigidity of the portion 2420 can be increased. Therefore, it is possible to prevent the first winning member 10400 from being damaged when an external force is applied to the gaming nail YK due to the collision of the gaming ball.

  Further, as described above, the cutout portion 10060h is formed to have substantially the same shape as the outer shape of the protruding portion 10422 in a front view, so that the first winning member 10400 is disposed on the base plate 60 when the first winning member 10400 is disposed on the base plate 60. The upper and lower surfaces of the setting portion 10422 can be brought into contact with the notch portion 10060h. This can prevent the first winning member 10400 from being damaged when a game ball comes into contact with the game nail YK.

  That is, when a game ball collides with the game nail YK from above, the impact of the collision pushes the head side of the game nail YK downward around the connection portion between the game nail YK and the first winning member 2400. Rotational force acts. In the tenth embodiment, the upper and lower surfaces of the protruding portion 10422 can be brought into contact with the notch portion 10060h at the rear side portion where the game nail YK is driven. Therefore, it is possible to bring the surfaces into contact with each other with respect to the rotational force pushing down the head side of the game nail YK about the connection portion between the game nail YK and the first winning member 2400. Therefore, it is possible to disperse the force by contacting the impact of the game balls with each other. As a result, breakage of the first winning member 10400 can be suppressed.

  Next, an eleventh embodiment will be described with reference to FIG. In the second embodiment, the case where the first winning member 2400 is directly fixed to the base plate 60 has been described. However, the first winning member 10400 of the eleventh embodiment has the base plate Indirectly attached to 60. The same parts as those in the above-described embodiments are denoted by the same reference numerals, and description thereof will be omitted.

  FIG. 30A is an exploded perspective front view of the first winning member 11400 and the base plate 60 in the eleventh embodiment, and FIG. 30B is a cross-sectional view of the first winning member 11400 and the base plate 60. . Note that the cross-sectional view of FIG. 30B corresponds to the cross-sectional view of FIG. Further, in FIGS. 30A and 30B, the outer shapes of the first winning member 11400 and the base plate 60 are illustrated in a simplified manner.

  As shown in FIG. 30, the base plate 60 in the eleventh embodiment includes a recess 2060c that is recessed downward from below the center opening of the base plate 60, and a base plate 60 that is connected to the recess 2060c. And a recessed portion 2060d formed in the front of the main body.

  Further, the outer peripheral surface (gap forming surface 11060d5) of the recessed portion 2060d in a front view is formed as an inclined surface inclined outward toward the front side. Thus, a gap can be formed between the first winning member 11400 and the recess 2060d. A fastening hole 6060d4 that penetrates in the front-rear direction and has an internal thread formed in the inner surface is formed in the recessed portion 2060d. Thereby, the first winning member 11400 can be fastened to the base plate 60.

  The winning opening unit 11300 includes a first winning member 11310 provided inside the concave portion 2060c of the base plate 60, and a first winning member 10400 and a second winning member 2500 provided on the front side of the base plate 60. FIG. 12).

  The first winning member 11400 includes a main body 11410 formed of a rectangular plate-like body that is long in a front view, a swelling portion 2420 that swells from the back side of the main body 11410, and a main body 11410 (front side). It is formed mainly with a game nail YK to be driven.

  The main body portion 11410 is formed of a horizontally long rectangular plate-shaped body as viewed from the front, and has an insertion hole 11418 formed through the same axis as the fastening hole 6060d4 of the base plate 60. The insertion hole 11418 is a hole through which the screw N3 for fastening the first winning member 11400 is inserted. The insertion hole 11418 is formed such that the front side is enlarged in diameter, and a large-diameter side head of a rubber collar GC described later can be inserted into the inside thereof. Further, the inner diameter of the insertion hole 11418 is formed larger than the outer diameter of the trunk portion on the small diameter side of the rubber collar GC. Thereby, the small diameter side of the rubber collar GC can be inserted inside the insertion hole 11418.

  The rubber collar GC is formed in an annular shape, and has a large-diameter portion that expands outward on one side in the axial direction of the trunk portion. The rubber collar GC is formed from a rubber-like elastic body, and can be elastically deformed by the action of an external force. Further, one rubber collar GC is provided on the front side and the back side of the insertion hole 11418 of the first winning member 11400, and the small diameter side (body portion) is inserted inside the insertion hole 11418.

  The first winning member 11400 is attached to the base plate 60 by inserting the screw N3 from the front side and screwing into the fastening hole 6060d4 of the base plate 60 in a state where the rubber collar GC is disposed inside the insertion hole 11418. It is attached. Therefore, an elastic member (rubber color GC) can be provided between the first winning member 11400 and the base plate 60.

  As described above, the gap forming surface 11060d5 is formed in the base plate 60, and the gap is formed between the recessed portion 2060d and the first winning member 11400, so that the elastic displacement of the elastic member (the color member GC) is performed. Accordingly, the collision between the first winning member 11400 and the base plate 60 when the first winning member 11400 is displaced relative to the base plate 60 can be suppressed.

  According to the winning opening unit 11300 configured as described above, the first winning member 11400 is broken when the gaming nail YK of the first winning member 11400 is broken, or when the gaming nail YK falls off from the first winning member 11400. After the first winning member 2500 is removed from the base plate 60, the defective first winning member 11400 can be removed and a new (normal) first winning member 11400 can be attached for repair.

  Further, as described above, the base plate 60 and the first winning member 11400 are provided with the rubber color GC made of a material having a smaller elastic coefficient than the first winning member 11400, and the first winning member 11400 is provided on the base plate 60 via the rubber color GC. Therefore, the first winning member can be easily displaced relative to the base plate 60 by utilizing the elastic deformation of the rubber collar GC. That is, due to the relative displacement (elastic deformation), the external force accompanying the collision of the game ball with the game nail YK is absorbed, and the damage of the first winning member 11400 can be suppressed.

  Further, as described above, since the gap forming surface 11060d5 is formed to be inclined outward toward the front side, the gap forming surface 11060d5 below the first winning member 11400 is lowered outward (to the front). It can be an inclined surface. Therefore, dust and the like between the first winning member 11400 and the base plate 60 can be dropped to the front side by utilizing the downward inclination of the gap forming surface 11060d5. Therefore, it is possible to prevent the dust or the like from being clogged between the first winning member 11400 and the base plate 60 and hindering the movement of the first winning member 11400.

  Further, the head of the screw N3 can be brought into close contact with the rubber collar GC. Therefore, the screw N3 can be hardly rotated, so that the screw N3 can be prevented from rotating and loosening due to an impact or the like when a game ball collides with the game nail YK.

  Further, since the rubber collar GC is formed in a substantially cylindrical shape and is interposed between the through hole and the axis of the screw N3, the displacement direction when the first winning member 11400 is relatively displaced with respect to the base plate 60. The degree of freedom can be increased. That is, relative displacement can be easily performed not only in a direction perpendicular to the axis of the screw N3 but also in a direction (twisting direction) inclined with respect to the axis of the screw N3. As a result, the external force caused by the collision of the game ball with the game nail YK is absorbed, and the damage of the first winning member 11400 can be suppressed.

  The rubber collar GC disposed on the back side of the first winning member 11400 has a large-diameter portion interposed between the base plate 60 and the first winning member 11400. The member 11400 can be connected only with the rubber collar GC (that is, at least a part of the vibration transmission path from the first winning member 11400 to the base plate 60 can be formed with only the rubber collar GC). Therefore, the first winning member 11400 can be easily displaced relative to the base plate 60, and the external force accompanying the collision of the game ball with the game nail YK can be easily absorbed.

  In addition, relative displacement can also be performed in the axial direction of the screw N3, and the degree of freedom in the relative displacement direction of the first winning member 11400 with respect to the base plate 60 can be increased. Therefore, also from this point, it is possible to easily absorb the external force caused by the collision of the game ball with the game nail YK.

  Further, since the outer diameter portion of the rubber collar GC is interposed between the base plate 60 and the first winning member 11400, it is possible to suppress the first winning member 11400 from tilting with respect to the base plate 60 by its own weight. . This is particularly effective when the rubber color GC is deteriorated (set) with the passage of time.

  Next, a twelfth embodiment will be described with reference to FIGS. In the second embodiment, the case where the entire front surface of the first winning member 2400 is formed as a flat surface has been described, but the front surface of the first winning member 12400 in the twelfth embodiment has a part thereof formed of the base plate 60. It is projected to the front side. The same parts as those in the above-described embodiments are denoted by the same reference numerals, and description thereof will be omitted.

  FIG. 31A is an exploded perspective front view of a first winning member 12400 in the twelfth embodiment, and FIG. 31B is an exploded top view of the first winning member 12400 of FIG. 32A is a top view of the first winning member 12400, and FIG. 32B is a partially enlarged top view of the first winning member 12400 in a range XXXIIb of FIG. 32A.

  As shown in FIGS. 31 and 32, the first winning member 12400 in the twelfth embodiment has a main body 12410 formed of a horizontally long rectangular plate-like body as viewed from the front, and swells from the back side of the main body 12410. It is mainly provided with a bulging portion 2420 and a game nail YK driven from the front side of the main body portion 12410.

  The main body part 12410 is formed of a plate-like body having a horizontally long rectangular shape in a front view, and mainly includes a through hole 2413 through which the flathead screw N2 is inserted, and an annular part 12419 projecting from the periphery of the hole into which the game nail YK is driven to the front side. It is formed in preparation for.

  Therefore, since the first winning member 11400 is formed so as to be able to suppress the damage of the first winning member 11400 due to the action of the external force on the gaming nail YK, the first winning member 10400 is formed when an external force is applied to the gaming nail YK by the collision of the game ball. Can be prevented from being damaged.

  In other words, the first winning member 12400 protrudes from the main body 12420 where the game nail YK is implanted and includes the annular portion 12419 surrounding the root of the game nail YK, so that the rigidity of the portion holding the game nail YK is increased. The height can be increased by the annular portion 12419. Therefore, it is possible to prevent the first winning member from being damaged when an external force is applied to the game nail due to the collision of the game ball.

  The inner diameter of the annular portion 12419 is set to be substantially the same as or slightly smaller than the outer diameter of the tip portion of the gaming nail YK. The width L4 from the inner edge to the outer edge of the annular portion 12419 (see FIG. 32B) and the protrusion L5 of the annular portion 12419 to the front side (see FIG. 32B) are defined as an annular shape. The outer surface of the part 12419 is set to a size that is located in the inner space N (see FIG. 32B) in a state where the game ball T is in contact with the front surface of the first winning member 12400 and the game nail YK. . In the present embodiment, the width L4 from the inner edge to the outer edge and the protrusion L5 of the annular portion 12419 to the front side are set to be substantially the same (L4 = L5).

  Thereby, it can suppress that the game ball T collides with the ring part 12419. As a result, it is possible to prevent the game ball flowing down the game area from colliding with the annular portion 12419 and damaging the annular portion 12419. In addition, the area for supporting the game nail YK can be increased by the amount that the annular portion 12419 protrudes toward the front side. As a result, it is possible to prevent the game ball T flowing down the game area from hitting the game nail YK and damaging the first winning member 12400.

  That is, since the ring portion 12419 is located on the first winning member 12400 side from the outer surface of the game ball abutting on the game nail YK and the planting surface 12419, the game ball T collides with the ring portion 12419. By doing so, it is possible to prevent the annular portion 12419 from being damaged.

  In addition, an inclined portion 12419a whose diameter increases toward the front side is formed on the inner edge of the protruding tip portion of the annular portion 12419. Thus, when the game nail YK is driven into the first winning member 12400, the tip of the game nail YK can be guided inside the annular portion 12419.

  Here, the first winning member 12400 is formed of a member different from the base plate 60, and when the gaming nail YK is broken or when the gaming nail YK falls off from the first winning member 12400, a new (normal) second winning member is formed. It can be replaced with one winning member 12400. Therefore, when forming a replacement part for the first winning member 12400, an operation of driving the gaming nail YK into only the first winning member 12400 is performed.

  Since the first winning member 12400 is a part smaller than the base plate 60, it is necessary to reliably position the first winning member 12400 when driving the gaming nail YK. Therefore, there is a possibility that the jig for driving the game nail YK into the first winning member 12400 may be complicated.

  On the other hand, in the twelfth embodiment, since the inclined portion 12419a is formed, it is possible to absorb a displacement when the gaming nail YK is driven into the first winning member 12400. As a result, the jig for driving the game nail YK into the first winning member 12400 can be simplified.

  The size of the inclined portion 12419a in the front-rear direction (the front-rear direction in FIG. 32B) is set smaller than the protrusion size of the annular portion 12419. Therefore, the formation of the annular portion 12419 can prevent the first winning member 12419 from being damaged, and can simplify a jig for driving the game nail YK into the first winning member 12400.

  Further, the annular portion 12419 has a larger cross-sectional area toward the main body portion 12410 and toward the main body portion 12410, so that the game ball can be prevented from colliding with the annular portion 12419, and the game nail YK can be prevented. Stiffness of the part holding the pressure can be further increased. That is, both the damage of the annular portion 12419 due to the direct collision of the game nail YK with the annular portion 12419 and the damage of the first winning member 12410 due to the collision of the game ball T with the game nail YK can be effectively reduced. Can be suppressed.

  Note that the cross-sectional area of the annular portion 12419 means a cross section obtained by cutting the annular portion 12419 on a plane orthogonal to the installation direction of the gaming nail YK. In this case, the cross-sectional shape of the annular portion is arbitrary, and examples thereof include a circle, an ellipse, and a polygon. However, it is preferable that the cross-sectional shape of the annular portion 12419 be circular. This is because it is possible to maximize the volume of the annular portion 12419 and further increase its rigidity while avoiding collision with the game ball.

  Next, a thirteenth embodiment will be described with reference to FIGS. In the second embodiment, the case where the second winning member 2400 is attached from the front side of the base plate 60 has been described. However, in the thirteenth embodiment, the second winning member 13400 is attached from the back side of the base plate 60. The same parts as those in the above-described embodiments are denoted by the same reference numerals, and description thereof will be omitted.

  FIG. 33A is a cross-sectional view of the game board 13 in the thirteenth embodiment, and FIG. 33B is a cross-sectional view of the game board 13 taken along the line XXXIIIb-XXXIIIb in FIG. FIG. 34 is an exploded perspective front view of the game board 13. 33 and 34 show a state where the second winning opening 2500 has been removed. 33 and 34, the outer shapes of the first winning member 13400 and the base plate 60 are illustrated in a simplified manner.

  As shown in FIGS. 33 and 34, the base plate 60 in the thirteenth embodiment has a concave portion that is recessed from the rear side (upper side in FIG. 33B) to the front side (lower side in FIG. 33B). 13060d. The recessed portion 13060d is formed to be large in the left-right direction in a stepwise manner toward the back side, and has a first housing portion 13060d7 located on the front side and a base plate 60 located on the back side of the first housing portion 13060d7. And a second accommodating portion 13060d8 connected to the rear surface of the main body.

  The first accommodating portion 13060d7 is a recess for accommodating a main body portion 13410 of a first winning member 13400 described later inside, and is formed to have a slightly larger outer shape than the outer shape of the main body portion 13410 in a front view. Further, the depth dimension of the first housing portion 13600d7 in the front-rear direction (the vertical direction in FIG. 33B) is substantially the same as or slightly larger than the thickness dimension of the main body portion 13410 in the front-rear direction. Accordingly, when the first winning member 13400 is disposed inside the recessed portion 2060c, it is possible to suppress the main body portion 13410 from protruding toward the second housing portion 13060d8.

  The second accommodating portion 13060d8 is a recess for accommodating a back member 13700 described later inside, and is formed to have a slightly larger outer shape than the outer shape of the back member 13700 in a front view. Further, the depth dimension of the second housing portion 13060d8 in the front-rear direction (vertical direction in FIG. 33B) is substantially the same as or slightly larger than the thickness dimension of the back member 13700 in the front-rear direction.

  The back member 13700 is formed in a horizontally long rectangle in a front view, and is formed integrally with the center frame 86. The longitudinal dimension of the back member 13700 is formed larger than the longitudinal dimension of the main body 13410 of the first winning member 13400.

  The first winning member 13400 includes a main body 13410 formed from a horizontally long rectangular plate-like body in front view, a bulge 7420 bulging from the front side of the main body 13410, and a bulge 7420 side (front side). ) Is mainly provided with game nails YK driven from the above.

  The main body part 13410 is formed with fastening holes 8415 for screwing screws for fastening the first winning member 13400 to the base plate 60 at both left and right ends. Thus, the first winning member 13400 and the base plate 60 can be fastened and fixed by inserting the flathead screw N2 into the inside of the through hole 7060e of the base plate 60 and screwing it into the fastening hole 8415.

  In this case, the first winning member 13400 is attached to the base plate 60 before the center frame 86 is attached to the base plate 60. That is, after the first winning device 13400 is fastened and fixed (arranged) to the base plate 60, the center frame 86 is attached to the base plate 60. Thus, the first winning member 13400 is disposed (sandwiched) between the front of the first housing 13060d7 of the base plate 60 and the front of the back member 13700. The bottom surface of the center frame 86 faces the upper end surface of the first winning member 13060d7.

  According to the gaming board 13 configured as described above, the center frame 86 is attached to the base plate 60 when the gaming nail YK of the first winning member 13400 is broken or when the gaming nail YK falls off from the first winning member 13400. , The defective first winning member 13400 can be removed and a new (normal) first winning member 13400 can be attached to repair the defective member.

  Here, a first game board member (base plate 60) and a second game board member (first winning member 13400) fastened and fixed to the first game board member to form a game board with the first game board member. A game machine equipped with a game machine is known. According to this gaming machine, the second gaming board member can be attached to and detached from the gaming board. Therefore, when a failure or breakage occurs in the second game board member, only the second game board member is replaced, and the replacement of the entire game board can be made unnecessary. However, in the above-described conventional gaming machine, for example, the fastening and fixing of the second gaming board member to the first gaming board member may be released (loose) due to vibration accompanying the game. However, there is a problem that the second game board member may fall off from the first game board member.

  On the other hand, in the thirteenth embodiment, since the removal of the first winning member 13400 from the base plate 60 can be regulated, for example, the fastening and fixing of the first winning member 13400 to the base plate 60 are released (loose). Even in this case, it is possible to prevent the first winning member 13400 from falling off from the first winning member 13400.

  That is, when the center frame 86 is disposed on the base plate 60, the bottom surface of the center frame 86 and the back member 13700 are at positions where the movement of the first winning member 13400 in the removal direction (upward and rear sides) can be restricted. Will be arranged. Accordingly, even when the fastening and fixing of the first winning member 13400 to the base plate 60 is released, the first winning member 13400 falls off the base plate 60 using the center frame 86 (the back member 13700). Can be suppressed.

  Since the back member 13700 is provided on the inner surface on the lower edge side of the central opening in the base plate 60, even if the holding (for example, fastening and fixing) of the back member 13700 with respect to the base plate 60 is released, the back member is removed. By utilizing its own weight, it can be maintained in a state of being placed on the inner surface on the lower edge side of the central opening. That is, it is possible to maintain a state in which the back member 13700 is provided at a position where the movement of the first winning member 13400 in the removal direction can be restricted. As a result, it is possible to prevent the first winning member 13400 from falling off the base plate 60.

  Next, a fourteenth embodiment will be described with reference to FIGS. In the second embodiment, the case where the second winning member 2500 is arranged on the front side of the first winning member 2400 has been described. However, the first winning member 14400 of the fourteenth embodiment has the second winning member on the front side. In addition to the arrangement of 2500, the passage forming member 13800 is arranged in an engaged state. The same parts as those in the above-described embodiments are denoted by the same reference numerals, and description thereof will be omitted.

  FIG. 31 is an exploded perspective front view of the game board 13 and the passage forming member 13800 in the fourteenth embodiment. 32A and 32B are cross-sectional views of the game board 13 and the passage forming member 13800. Note that FIG. 32A and FIG. 32B correspond to the cross-sectional view of FIG. In addition, FIG. 32A illustrates a state before the passage forming member 13800 is attached to the game board 13, and FIG. 32B illustrates a state after the passage forming member 13800 is attached to the game board 13. . In FIG. 31, the illustration of the second winning member 13500 is omitted, and the outer shape is illustrated by a chain line.

  As shown in FIGS. 35 and 36, the first winning member 14400 in the fourteenth embodiment includes a main body 2410 formed of a horizontally long rectangular plate-shaped body as viewed from the front, and a rear side of the main body 2410 (see FIG. a) It mainly includes a bulging portion 2420 bulging from the left side) and a game nail YK driven from the front side of the main body portion 2410.

  The bulging portion 2420 includes a concave portion 14423a. The recess 14423a is recessed upward (upward in FIG. 36 (a)) on the lower surface (lower surface in FIG. 36 (a)) on the base side (right side in FIG. 36 (a)) of the bulging portion 2420. You.

  The concave portion 14423a is a concave portion into which a projecting portion 14812 of the passage member 14800 described later is inserted, and the inside shape is set to be substantially the same as the external shape of the projecting portion 14812. Further, the recessed dimension of the recessed portion 14423a is set to be larger than the projecting dimension of the projecting portion 14812. Therefore, the projecting portion 14812 can be inserted inside the recessed portion 14423a.

  The passage member 14800 is formed to have a rectangular shape whose outer shape is long in the vertical direction, and has an internal space inside. The passage member 14800 is formed mainly at the upper end of the front side (the first winning member 14400 side) with an opening 14811 that allows communication between the internal space and the outside, and a projecting portion 14812 that protrudes upward from the upper end surface. You.

  The opening 14811 is formed on the back side (the left side in FIG. 36B) of the first winning opening 64 in a state where the passage member 14800 is arranged on the game board 13. Thus, the game balls sent from the first winning opening 64 to the back side can be sent inside the passage member 14800 through the opening 14811.

  The protruding portion 14812 is formed to protrude upward (upward in FIG. 36B) from an end on the opening 14811 side (right side in FIG. 36B). Insertion of the projecting portion 14812 into the recessed portion 14423a involves displacing the passage member 14800 on the back side of the base plate 60 and upward while the first winning member 14400 is disposed on the base plate 60. Done in

  The passage member 14800 is attached to the base plate 60 by inserting a screw (not shown) from the back side and screwing the screw to the back side of the base plate 60.

  According to the gaming board 13 configured as described above, when the gaming nail YK of the first winning member 14400 is broken or when the gaming nail YK falls off from the first winning member 14400, the passage member 14800 is removed. Later, the defective first winning member 13400 can be removed and a new (normal) first winning member 14400 can be attached to repair the defective member.

  Here, if the first winning member 14400 can be removed only by working from the front side, when the front frame 14 is opened due to the wrongdoing of the player, the first winning member 14400 is exchanged for the first winning member 14400 brought in by the player. It is easy to be.

  On the other hand, a projecting portion 14812 is formed on the first winning member 14400, a recessed portion 14423a capable of receiving the projecting portion 14812 is recessed in the passage member 14800, and the projecting portion 14812 is recessed. The engagement with the portion 14423a regulates the movement of the first winning member 14400 in the removal direction, so that the projecting portion 14812 can be shielded from the outside by the recessed portion 14423a. Therefore, it is possible to prevent the engagement between the projecting portion 14812 and the recessed portion 14423a from being illegally released.

  Furthermore, as described above, since the passage member 14800 is attached to the back of the base plate 60 from the back of the game board 13 by screws (not shown), it is possible to prevent unauthorized removal of the first winning member 14400.

  That is, since the projecting portion 14812 of the first winning member 14400 and the recessed portion 14423a of the passage member 14423 are engaged via the recessed portion 2060c, the passage member 14423 is used from the front using the base plate 60. It can be difficult to access. Therefore, it is possible to prevent the engagement between the projecting portion 14812 and the recessed portion 14423a from being illegally released.

  Further, since the first winning member 14400 can be engaged with the passage member 14800, if the flathead screw N2 for fastening and fixing the first winning member 14400 to the base plate 60 comes off due to an impact or the like, the first winning member 14400 becomes the first member. The winning member 14400 can be prevented from moving to the front side or the rear side of the base plate 60 and dropping from the base plate 60.

  Next, a first winning member 15400 in the fifteenth embodiment will be described with reference to FIG. In the second embodiment, the case where only the first winning member 2400 is fastened and fixed to the base plate 60 has been described. However, in the fifteenth embodiment, the hook portions 15431 of the first winning member 15400 engage with the base plate 60. Is done. The same parts as those in the above-described embodiments are denoted by the same reference numerals, and description thereof will be omitted.

  FIG. 37 (a) is a perspective front view of a first winning member 15400 in the fifteenth embodiment, and FIG. 37 (b) is a cross-sectional view of the game board 13. FIG. 37 (b) corresponds to the cross-sectional view of FIG. 14 (c) and shows a state in which the second winning member 2500 has been removed.

  As shown in FIG. 37, the first winning member 15400 in the fifteenth embodiment includes a main body 2410 formed of a rectangular plate-like body that is long in a front view, and a rear side of the main body 2410 (the upper side in FIG. 37B). ), And a game nail YK driven from the front side of the main body 2410.

  The bulging portion 2420 protrudes rearward (upward in FIG. 37 (b)) of both ends in the longitudinal direction (FIG. 37 (b) left-right direction) of the main body 2410, and its protruding tip is in the longitudinal direction (FIG. 37 (b)). FIG. 37 (b) (left-right direction) is provided with a hook-shaped portion 15431 that is bent outward.

  The hook-shaped portion 15431 is arranged at a position where its tip overlaps the rear side of the base plate 60 (above the upper part of FIG. 37B) in a state where the first winning member 15400 is arranged on the base plate 60. Therefore, the first winning member 15400 can be brought into a state of being engaged with the base plate 60. Therefore, when the countersunk screw N2 for fastening the first winning member 15400 to the base plate 60 comes off due to an impact or the like, the first winning member 15400 falls to the front side of the base plate 60 (the lower side in FIG. 37B). Can be prevented. As a result, when the countersunk screw N2 comes off during the game of the player, the player can continue the game.

  The hook-shaped portion 15431 is formed at substantially the same height position as the through-hole 2413 formed above the four through-holes 2413 formed in the main body portion 2410, and the back surface of the bent portion of the protruding tip is formed. 37B is formed at a position overlapping with the axis of the through hole 2413. That is, the back surface of the bent portion of the hook-shaped portion 15431 covers the through hole 2413 opened in the base plate 60.

  Also, the hook-shaped portion 15431 has an inclined surface 15431a formed on the outer surface of the protruding tip (the outer surface in the longitudinal direction of the main body portion 2410). The inclined surface 15431a is formed so as to be inclined such that the width thereof becomes narrower toward the protruding tip.

  Accordingly, when the first winning member 15400 is disposed on the base plate 60, the first winning member 15400 can be disposed by being inserted from the front side of the base plate 60. That is, as described above, the width of the bulging portion 2420 in the longitudinal direction of the main body 2410 is reduced by the amount of bending of the hook-shaped portion 15431 in the longitudinal direction of the main body 2410 (the left-right direction in FIG. 37B). Is larger than the distance between the opposing concave portions 2060c, so that when the first winning member 15400 is provided, the hook-shaped portion 15431 cannot be inserted between the opposing concave portions 2060c. Since the inclined surface 15431 is formed in the portion 15431, the hook-shaped portion 15431 can be elastically deformed inward by bringing the inclined surface 15431a into contact with the wall surface of the recessed portion 2060c. From the front side of the base plate 60.

  Therefore, with the attachment of the first winning member 15400 to the base plate 60, the base plate 60 and the first winning member 15400 are directly engaged via the hook-shaped portion 15431a, and the first winning member 15400 is moved in the removal direction. Is regulated, it is not necessary to separately perform a step for preventing the first winning member 15400 from falling off. Therefore, the work of replacing the first winning member 15400 can be simplified, and the step of preventing the first winning member 15400 from falling out can be prevented from being forgotten.

  In addition, since the hook portion 15431 is formed on the first winning member 15400, a new hook portion 15431 can be used when the first winning member 15400 is replaced. That is, in the configuration in which the hook-like portion 16541 is disposed on the base plate 60 and the claw portion is engaged with the first winning member 15400, the elastic deformation of the hook-like portion 16541 is repeated when the number of replacements increases, and the elastic force is reduced. Because of the decrease, the engagement is easily released. On the other hand, according to the fifteenth embodiment, even when the number of replacements increases, a new hook-shaped portion 15431 can be used for each replacement, so that the reliability of engagement can be ensured.

  On the other hand, when the first winning member 15400 is to be removed from the base plate 60, as described above, the end of the hooked portion 15431 on the bending tip side is formed at the same height position as the hooked portion 15431. Since it is formed at a position overlapping the axis of 2413, after removing the countersunk screw N2 that fastens the first winning member 15400 and the base plate 60, the outer shape of the through hole 2413 of the first winning member 15400 is smaller than that of the through hole 2413. By inserting a cylindrical jig having a small size, the hook-shaped portion 15431 can be elastically deformed and removed.

  That is, for example, there is no need to open the game board 13 and perform an operation of releasing the engagement of the hook-shaped portion 15431 from the back side thereof, and release the engagement of the hook-shaped portion 15431 while the game board 13 is closed. it can. Therefore, the workability of the work of removing the first winning member 15400 from the game board 13 can be improved, that is, it is not necessary to open the game board 13 to release the engagement of the hook-shaped portion 15431. The exchange of the first winning member 15400 can be completed from the front with the game board 13 kept closed.

  In addition, in the normal game state, the inside of the hole for releasing the engagement of the hook-shaped portion 15431a can be hidden from the player, so that the design of the game board 13 can be ensured.

  Next, a first winning member 16400 in the sixteenth embodiment will be described with reference to FIG. In the second embodiment, the case where the rear side of the bulging portion 2420 of the first winning member 2400 is arranged on substantially the same plane as the rear surface of the base plate 60 has been described. The bulging portion 16420 of 16400 protrudes to the back side of the base plate 60. The same parts as those in the above-described embodiments are denoted by the same reference numerals, and description thereof will be omitted.

  FIGS. 38A and 38B are cross-sectional views of the game board 13 and the front frame 14 in the sixteenth embodiment. 38 (a) and 38 (b), the illustration of the second winning member 2500 is omitted. FIGS. 38 (a) and 38 (b) correspond to the cross-sectional view of FIG. 14 (c). Further, FIG. 38 (a) illustrates a state where the first winning member 16400 is attached to the base plate 60, and FIG. 38 (b) illustrates a state where the first winning member 16400 is removed from the base plate 60. Is done.

  As shown in FIG. 38 (a), in the sixteenth embodiment, the first winning member 16400 is formed from a horizontally long rectangular plate-like body in a front view, and a rear side of the main body 2410 (see FIG. 38 (a) (upper side), and a game nail YK driven from the front side of the main body 2410.

  The bulging portion 16420 is formed to bulge toward the back side of the main body portion 2410, and a width dimension L7 (see FIG. 38A) in the front-rear direction (FIG. 38A vertical direction) is formed on the base plate 60. The distance dimension L8 (see FIG. 38 (a)) from the head of the gaming nail YK to the glass unit 16 of the front frame 14 in a state where the first winning member 16400 is provided (L7> L8).

  Accordingly, as shown in FIG. 38B, the countersunk screws N1 and N2 for fastening the first winning member 16400 and the second winning member 2500 to the base plate 60 are removed, and the first winning member 16400 is moved to the front side (FIG. 38). (B) When it is displaced to the lower side, the first winning member 16400 can be prevented from falling out of the base plate 60.

  More specifically, since the width dimension L7 of the bulging portion is set to be larger than the distance dimension L8 from the head of the game nail YK to the glass unit 13, the head of the game nail YK and the glass unit 13 abut. When the first winning member 16400 is displaced by the maximum distance, at least a part of the bulging portion 16420 can be located between the opposing concave portions 2060c. As a result, even when the fastening of the first winning member 16400 to the base plate 60 is released, the first winning member 16400 can be prevented from falling off the base plate 60 by using the glass unit 13.

  Further, in this case, the tip of the gaming nail YK of the first winning member 16400 abuts on the glass unit 13, so that the first winning member 16400 can be prevented from falling off the base plate 60. That is, the thickness dimension (dimension in the removal direction) of the first winning member 16400 can be reduced by the length of the gaming nail YK that can be used.

  Next, a seventeenth embodiment will be described with reference to FIGS. In the second embodiment, the case where only the first winning member 2400 is fastened and fixed to the base plate 60 has been described.

Located at the location.

  The center frame 86 has a bent portion 17086a bent at the rear side at the lower end (the lower end in FIG. 40B). The lower surface of the bent portion 17086 is formed with an inclined surface 17086a1 that is inclined upward toward the back side.

  In addition, the facing distance L9 from the substantially center position of the inclined surface 17086a1 in the front-rear direction (the left-right direction in FIG. 40B) to the end surface of the base plate 60 is set such that the first winning member 17400 is disposed on the base plate 60. In this state, the first winning member 17400 is formed to be smaller than the vertical dimension (the vertical direction in FIG. 40B). Therefore, when the first winning member 17400 is provided on the base plate 60, the sphere 17452 can be inserted into the inside of the holding portion 17451.

  In this case, as described above, since the inclined surface 17086a1 is inclined upward toward the back side, the force of the sphere 17452 being pushed up by the spring member 17453 causes the entire first winning member 17400 to move toward the back side (FIG. 40B). (Left side).

  Therefore, when the countersunk screw N2 for fastening and fixing the first winning member 17400 to the base plate 60 is removed by impact or the like, the first winning member 17400 falls to the front side of the base plate 60 (D09 (b) right side). Can be suppressed. As a result, if the dish screw N2 comes off during the game, the player can continue the game.

  In addition, since the ball 17452 is in a state where the ball 17452 is elastically supported by the spring member 17453, the ball plunger 17450 causes the ball 17452 to act as a mass when the game ball hits the game nail YK. Can be. That is, the ball plunger 17450 can function as a dynamic damper. As a result, the vibration caused by the collision of the game ball with the game nail YK can be suppressed, and the damage of the game nail YK and the first winning member 17400 can be suppressed. In particular, since the expansion and contraction direction of the spring member 17453 (the direction of elastic support of the sphere 17452) is set to the up-down direction and coincides with the falling direction of the game ball (that is, the direction of collision with the game nail YK), the above-described game ball The function (prevention of breakage) as a dynamic damper against a collision can be effectively exhibited.

  Next, an eighteenth embodiment will be described with reference to FIGS. In the second embodiment, the case where it is necessary to remove the second winning member 2500 when removing the first winning member 2400 from the base plate 60 is described. However, in the eighteenth embodiment, the first winning member 18400 is removed. When removing the second winning member 2500 from the base plate 60, the operation of removing the second winning member 2500 is unnecessary. The same parts as those in the above-described embodiments are denoted by the same reference numerals, and description thereof will be omitted.

  First, the overall structure of the game board 13 in the eighteenth embodiment will be described with reference to FIGS. FIG. 41 (a) is a front view of the game board 13 in the eighteenth embodiment, and FIG. 41 (b) is a cross-sectional view of the game board 13 along the line XLIb-XLIb in FIG. 41 (a). FIG. 42 is an exploded perspective front view of the game board 13. FIG. 42 shows a state in which the center frame 86 has been removed. 41 and 42, the outer shapes of the first winning member 18400 and the base plate 60 are shown in a simplified manner.

  As shown in FIGS. 41 and 42, the base plate 60 in the eighteenth embodiment includes a recessed portion 18060c that is recessed downward (downward in FIG. 41A) from the center opening side to which the center frame 86 is attached. A recessed portion connected to both ends in the left-right direction (left-right direction in FIG. 41A) of the recessed portion 18060c and recessed from the front side (right side in FIG. 41B) to the back side (left side in FIG. 41B). 18060d, and a second recess 18060j that is recessed downward so as to be continuous with the center in the left-right direction of the recess 18060c.

  The recessed portion 18060c is formed to be recessed from the center opening side in a rectangular shape that is horizontally long in front view, and the shape in front view is substantially the same as the shape of the bulging portion 18420 of the first winning member 18400 described later in rear view. Is set.

  The recessed portion 18060d is formed so as to be continuous with both left and right ends of the recessed portion 18060c, and is recessed from the front side to the rear side of the base plate 60 to a substantially central position in the plate thickness direction. The recess 18060d is a portion for accommodating a part of the main body portion 18410 (a portion projecting downward from the bulging portion 18420) of the first winning member 18400, which will be described later, and extends downward from the bulging portion 18420 in a front view. It is recessed downward with substantially the same recess dimension as the amount of projection of the projecting main body portion 18410.

  A fastening hole 1860d4 penetrating from the front side to the back side is formed in the recess 18060d. A female screw for screwing a countersunk screw N2 for fastening and fixing the first winning member 18400 to the base plate 60 is formed inside the fastening hole 18060d4.

  The second recessed portion 18060j is an opening that allows the game balls flowing into the first winning opening 64 of the second winning member 2500 to flow to the back side of the base plate 60, and the first winning of the second winning member 2500. It is recessed below 64.

  The winning opening unit 18300 includes a first winning member 18400 disposed inside the recessed portion 18060c of the base plate 60, and a front side (the right side in FIG. 41B) of the first winning member 18400 and the base plate 60. The second winning member 2500 is provided.

  The first winning member 18400 includes a main body portion 18410 formed from a rectangular plate-like body that is horizontally long in front view, a bulging portion 18420 that bulges from the back side (the left side in FIG. 41B) of the main body portion 18410, It is mainly provided with a game nail YK driven from the portion 18410 side (front side).

  The main body portion 18410 has a through hole 18413 formed in the longitudinal direction (the left-right direction in FIG. 41A) at both ends of the lower end (the lower side in FIG. 41A) in the front-rear direction. You. The through hole 18413 is formed coaxially with the fastening hole 1860d4 formed in the recess 18060d. Thereby, the countersunk screw N2 inserted through the through hole 18413 is screwed into the fastening hole 1860d4, and the first winning member 18400 can be fastened and fixed to the base plate 60.

  Further, the through hole 18413 is formed so as to increase in diameter toward the front surface side into which the flathead screw N2 is inserted. Thereby, the head of the flathead screw N2 can be inserted into the inside of the through hole 18413. Thereby, when the first winning member 18413 is fastened to the base plate 60, it is possible to suppress the tip of the gaming nail YK from protruding into the gaming area.

  The upper end of the bulging portion 18420 is formed flush with the upper end of the main body portion 18410, and the lower end of the main body portion 18400 protrudes downward from the lower end of the bulging portion 18420. The bulging portion 18420 is formed over the entire area of the main body 18400 in the left-right direction.

  When the first winning member 18400 is provided on the base plate 60, a part of the center frame 86 provided at the central opening of the base plate 60 is partially upper end portion of the first winning member 18400 (FIG. 41 (b)). ) Upper end) and a portion (front projection) that overlaps in the front-rear direction (left-right direction in FIG. 41B). Therefore, the movement of the first winning member 18400 in the pulling-out direction can be restricted by the center frame 86, so that the shape of the base plate 60 can be simplified and its formation can be facilitated. It is preferable that the second winning member 2500 and the center frame 86 are disposed on both sides of the first winning member 18400 in the direction of gravity. This is because the shape of the base plate 60 can be simplified.

  Further, in a state where the first winning member 18400 is disposed on the base plate 60, the center frame 86 is located at a position separated by a predetermined distance from the upper end surface of the first winning member 18400, and is located on the rear side from the front projection. A protruding projection 18086b is formed.

  In the state where the first winning member 18400 is provided on the base plate 60, the distance L10 between the protrusion 18086b and the facing of the first winning member 18400 (see FIG. 41B) is determined by the first winning member. The vertical dimension L11 (see FIG. 41B) of the region where the 18400 and the second winning member 2500 overlap in the front-back direction is set to be larger.

  Next, a procedure for removing the first winning member 18400 from the base plate 60 will be described with reference to FIG. 43 (a) to 43 (c) are cross-sectional views of the game board 13. FIG. FIGS. 43 (a) to 43 (c) correspond to the cross-sectional view of FIG. 41 (b). FIGS. 43 (a) to 43 (c) sequentially show transition states when the first winning member 18400 is removed.

  First, as shown in FIG. 43A, when removing the first winning member 18400, the countersunk screw N2 that fastens and fixes the first winning member 18400 to the base plate 60 is removed.

  Second, as shown in FIG. 43 (b), the first winning member 18400 is lifted upward with respect to the base plate 60. As described above, the distance dimension L10 between the facing of the projecting portion 18086b and the first winning member 18400 is larger than the vertical dimension L11 of the region where the first winning member 18400 and the second winning member 2500 overlap in the front-rear direction. Therefore, by lifting the first winning member 18400 upward, the lower end (the lower part in FIG. 43B) of the first winning member 18400 can be positioned higher than the second winning member 2500.

  Therefore, by rotating the lower end of the first winning member 18400 forward from the state shown in FIG. 43 (b), the lower end of the first winning member 18400 is rotated as shown in FIG. 43 (c). Can be located forward of the front of the base plate 60. Finally, by pulling out the lower end of the first winning member 18400 in the lateral direction of the main body 18410, the upper end of the first winning member 18400 can be pulled out from the base plate 60. When the first winning member 18400 is attached, the first winning member 18400 can be attached to the base plate 60 by performing the reverse procedure.

  Therefore, when the gaming nail YK of the first winning member 18400 is broken or when the gaming nail YK falls off from the first winning member 18400, the defective first winning member 18400 is removed and a new (normal) first winning member is removed. It can be repaired by attaching 18400.

  Here, a first game board member (base plate 60) and a second game board member (first winning member 18400) disposed on the first game board member and forming a game board together with the first game board member. A game machine equipped with a game machine is known. According to such a gaming machine, since the second game board member is fastened and fixed to the first game board member by the screw member (counterhead screw N2), the screw member is incorrectly removed or inadvertently caused by vibration during the game. When loosened, the second game board member may fall off from the first game board member. On the other hand, the present applicant disposes the second member on the first game board member in a state of being superimposed on a part of the second game board member, so that the engagement of the two by the superimposed portion is achieved. Utilizing the technique, the present inventor has conceived a technique for preventing the second game board member from falling off the first game board member (not known at the time of filing the present application).

  However, in the above-described technique, when performing the replacement work of the second game board member, not only the second game board member but also the second member needs to be removed from the game board, so that the man-hour is increased accordingly. However, it has been found that there is a problem that the replacement work of the second game board member becomes complicated.

  On the other hand, according to the eighteenth embodiment, the first winning member 18400 is detachably formed in a state where the second winning member 2500 is held by the base plate 60. The replacement work of the first winning member 18400 can be simplified. That is, since it is not necessary to remove the second winning member 2500 from the base plate 60, not only the number of steps in the process of reattaching the second winning member 2500 is suppressed, but also the worker loses the second winning member 2500. In addition, it is possible to suppress a mistake in mounting the second winning member 2500.

  In other words, the second winning member 2500 is disposed at a position where the movement in the direction in which the first winning member 18400 is pulled out can be restricted, and the first winning member 18400 is pulled out by moving it upward in a direction different from the pulling direction. Since the movement in the direction is allowed, the first winning member 18400 can be removed without removing the second winning member 2500 from the base plate 60. In addition, the first winning member 18400 can be attached while the second winning member is provided on the base plate 60. Accordingly, the number of steps can be reduced correspondingly, and the replacement work of the first winning member 18400 can be simplified.

  In addition, since the moving direction in allowing the movement of the first winning member 18400 in the pulling-out direction is parallel to the direction of gravity, the movement of the first winning member 18400 in the pulling-out direction is restricted by the second winning member 2500. The state in which the first winning member 18400 is arranged at a possible position can be maintained by the weight of the first winning member 18400 (action of gravity). That is, even if the countersunk screw N2 that fixes the first winning member 18400 to the base plate 60 is incorrectly removed or unnecessarily loosened due to vibration during the game, the first winning member 18400 partially removes the second winning member 18400 from the second winning member 18400. Since the position is superimposed on the winning member 2500 (the position where the movement in the pull-out direction is restricted), the first winning member 18400 falls off the base plate 60 due to the engagement of the two by the superposed portion. Can be suppressed.

  Furthermore, since the first winning member 18400 has the lower end portion of the main body portion 18410 disposed between the back of the base member 2510 of the second winning member 2500 and the front of the recess 18060d, the first winning member 18400 When the countersunk screw N2 for fastening and fixing the 18400 is removed by an impact or the like, it is possible to prevent the first winning member 18400 from dropping to the front side (the right side in FIG. 41B) of the base plate 60. As a result, even if the countersunk screw N2 comes off during the game, the player can continue the game.

  Next, a nineteenth embodiment will be described with reference to FIGS. In the second embodiment, the case where it is necessary to remove the second winning member 2500 when removing the first winning member 2400 from the base plate 60 is described. However, in the nineteenth embodiment, the first winning member 19400 is removed. When removing the second winning member 19500 from the base plate 60, an operation of removing the second winning member 19500 is unnecessary. The same parts as those in the above-described embodiments are denoted by the same reference numerals, and description thereof will be omitted.

  First, the overall structure of the game board 13 according to the nineteenth embodiment will be described with reference to FIGS. FIG. 44 is an exploded perspective front view of the game board 13 in the nineteenth embodiment. FIG. 45 (a) is a front view of the game board 13, and FIG. 45 (b) is a cross-sectional view of the game board 13 along the line XLVb-XLVb in FIG. 45 (a). FIG. 44 shows a state in which the center frame 86 has been removed. In FIGS. 44 and 46, the outer shapes of the first winning member 18400 and the base plate 60 are simplified.

  As shown in FIGS. 44 and 45, the winning opening unit 19300 in the nineteenth embodiment includes a first winning member 2400 disposed inside the recessed portion 2060c of the base plate 60, and the first winning member 2400 and the first winning member 2400. The second winning member 19500 is provided on the front side of the base plate 60 (the right side in FIG. 45B).

  The second winning member 19500 includes a base member 19510 formed of a rhombic plate-like body in a front view, a ball winning member 320 protruding from the front side (the right side in FIG. 45B) of the base member 19510, and a base. It is formed mainly with a passage forming member 19330 located on the opposite side of the ball winning member 320 with the member 19510 interposed therebetween.

  The size of the base member 19510 is set to be larger in the left-right direction (the left-right direction in FIG. 45A) when viewed from the front than the recessed portion 2060 c of the base plate 60. Thus, the base member 19510 can be arranged on the front side (the right side in FIG. 45B) of the recessed portion 2060c, and both ends in the left-right direction of the base member 2510 can be brought into contact with the front surface of the base plate 60.

  The base member 19510 includes an opening 311 that is opened at a substantially central position in the plate thickness direction (left and right directions in FIG. 45B) as viewed from the front, and a sliding groove 19512 that penetrates both ends in the left and right direction in the plate thickness direction. It is formed mainly in preparation.

  The sliding groove 19512 is formed so as to extend in the vertical direction (vertical direction in FIG. 45 (a)), and has its inner surface facing inward from the front side to the rear side (back side in FIG. 45 (a)). It is formed inclined. The sliding groove 19512 is an opening through which a countersunk screw N1 for fastening and fixing the second winning member 19500 to the base plate 60 is inserted. The width of the inner surface of the sliding groove 19512 is smaller than the outer shape of the tip (shaft) of the countersunk screw N1. Largely formed.

  In the sliding groove 19512, an accommodation portion 19512a is formed at a lower end portion (a lower end portion in FIG. 45A) formed on an inclined surface having an outer shape larger than the head of the flathead screw N2. Furthermore, when the second winning member 19500 is disposed at the position where the base plate 60 is disposed (the position shown in FIG. 45), the accommodation portion 19512a is set on the same axis as the axis of the flathead screw N2. Thereby, the position where the second winning member 19500 is attached can be determined. Further, since the sliding groove 19512 extends in the up-down direction, the second winning member 19500 can be moved downward from the position shown in FIG. 45 by weakening the fastening of the countersunk screw N1.

  The passage forming member 19330 is formed to protrude rearward from the periphery of the opening 311 of the base member 19310. The passage forming member 19330 is formed in a substantially U-shape whose lower side is curved in a rear view, and a space large enough to allow a game ball to pass therethrough is formed inside. Thus, the game ball flowing into the first winning port 64 can be sent to the back side of the passage forming member 19330 and can be sent to the passage member 19800 communicated with the back side of the passage forming member 19330.

  In addition, the passage forming member 19330 includes an extended portion 19340 that protrudes into a later-described passage member 19800 from the rear end of the left and right sides (the left and right sides in FIG. 45A). The extending portion 19340 includes a pair of rod-shaped protrusions 19341 protruding from both ends of the left and right wall surfaces of the passage forming member 330 to the rear side (the left side in FIG. 45B), and protruding tips of the pair of protrusions 19341. And a metal body 19343 connected to the connecting portion 19342 and extending downward.

  The protruding portion 19341 protrudes from the upper end of the passage forming member 19330 to the rear side, and the protruding tip side is inserted into an opening 19811 of a passage member 19800 described later. The protruding portion 19341 has its protruding tip located substantially at the center in the front-rear direction of the space formed inside the passage member 19800.

  The connecting portion 19342 is formed of a rod-shaped body, and both ends are connected to the projecting tips of the pair of projecting portions 19341, respectively. Further, a groove to which a metal body 19343 described later is press-fitted and connected is formed on the lower surface of the connecting portion 19342. The connection between the connecting portion 19342 and the metal body 19343 is not limited to press-fitting, but may be performed by bonding, screwing, or the like.

  The metal body 19343 is a plate member formed of a metal material (in the present embodiment, iron), and has a width dimension in the left-right direction (FIG. 45 (a) left-right direction) that is equal to the width of the internal space of the passage member 19800 described later. It is set smaller than the size. Further, the metal body 19343 is disposed so as to be inclined downward (left side in FIG. 45 (b)) toward the lower side (lower side in FIG. 45 (b)) in a state where it is connected to the connecting portion 19342.

  The metal body 19343 is located above the lower end surface of the passage forming member 19330 when the second winning member 19500 is fastened and fixed to the base member 60, and has the shortest distance to the lower surface of the opening 19811 of the passage member 19800. The distance dimension L11 (see FIG. 45 (b)) is set to be larger than the outer diameter of the game ball. Thereby, when the game ball flowing into the first winning opening 64 of the second winning member 19500 rolls on the passage forming member 19330 and is thrown inside the passage member 19800, the game ball is transferred to the passage forming member 330. It can collide with the front side.

  Therefore, it is not necessary to change the throwing direction of the game balls by causing the game balls to collide with the inner wall of the passage member 19800, so that the passage member 19800 can be prevented from being damaged. Further, since metal body 19343 is formed of iron and has higher rigidity than the resin forming passage member 19800, breakage of passage member 19800 can be suppressed. Further, when the metal body 19343 is damaged, the metal body 19343 can be replaced by removing the flathead screw N1 for fastening the second winning member 19500 to the base plate 60. Therefore, repair of the metal body 19343 can be simplified.

  Note that the metal body 19343 is not limited to iron. Other members may be employed as long as the material is detected by the sensor device SE described later. For example, it may be formed of aluminum or stainless steel.

  The passage member 19800 has a rectangular shape whose outer shape is long in the up-down direction, and is formed with an internal space inside. The passage member 19800 is provided at an upper end on the front side (the right side in FIG. 45B) and is provided at an upper end side of the internal space of the passage member 19800 extending in the up-down direction, with an opening 19811 communicating the internal space with the outside. And a sensor device SE.

  The opening 19811 is formed on the back side (the left side in FIG. 45B) of the first winning opening 64 in a state where the passage member 19800 is disposed on the game board 13. Thereby, the game balls sent from the first winning member 64 to the back side can be sent to the inside (inner space) of the passage member 19800 through the opening 19811.

  The sensor device SE is a member that detects the number of game balls passing through the inside of the passage member 19800, and has an opening that has an inner diameter larger than the outer diameter of the game balls and penetrates vertically.

  The passage member 19800 is attached to the base plate 60 by inserting a screw (not shown) from the rear side and screwing the screw to the rear side of the base plate 60.

  Next, the displacement of the second winning member 19500 will be described with reference to FIG. FIG. 46 (a) is a front view of the game board 13, and FIG. 46 (b) is a cross-sectional view of the game board 13 along the line XLVIb-XLVIb in FIG. 46 (a). 46 (a) and 46 (b) show a state in which the countersunk screw N1 for fastening the second winning member 19500 to the base plate 60 is loosened.

  As shown in FIG. 46, when the countersunk screw N1 for fastening the second winning member 19500 is loosened, the head of the countersunk screw N1 is slightly separated from the front surface of the second winning member 19500, so that the tip end of the countersunk screw N1 ( Shaft portion) can slide inside the sliding groove 19512, and the second winning member 19500 can be displaced downward.

  Thus, the first winning member 2400 and the second winning member 19500 can be arranged at positions where they do not overlap in the front-rear direction. Therefore, when the game nail YK of the first winning member 2400 is broken or when the game nail YK falls off from the first winning member 2400, the second first winning member 19500 is not removed from the base member 60, and the defective first nail is removed. Repair can be performed by removing the winning member 2400 and attaching a new (normal) first winning member 2400.

  That is, the second winning member 19500 is disposed on the base plate 60 so as to be displaceable between a restriction position for restricting the removal of the first winning member 2400 and an allowable position for permitting the removal of the first winning member 2400. The first winning member 2400 can be removed without removing the second winning member 19500 from the game board 13. Further, the first winning member 2400 can be attached while the second winning member 19500 is provided on the base member. Therefore, the man-hour can be reduced correspondingly, and the work of replacing the first winning member 2400 can be simplified. Further, since the second winning member 19500 is not removed from the base plate 60, it is possible to prevent the user from forgetting to attach the second winning member 19500 when the first winning member 2400 is replaced.

  Further, since the allowable position of the second winning member 19500 that allows the removal of the first winning member 2400 is set below the regulated position in the direction of gravity, the second winning member 19500 is maintained at the allowable position by its own weight. be able to. That is, when replacing the first winning member 2400, the operator does not need to hold the second winning member 19500 at the allowable position. Therefore, the number of steps can be reduced, and the work of replacing the first winning member 2400 can be simplified.

  When the second winning member 19500 is displaced downward, the shortest distance dimension L12 between the front surface of the metal body 19343 and the lower surface of the opening 19811 of the passage member 19800 (see FIG. 46 (b)) It is made smaller than the outer diameter of the game ball. This can prevent a game ball from passing through the passage member 19800 when the second winning member 19500 is forgotten to be returned to a normal position after the first winning member 2400 is replaced. As a result, it is possible to prevent a state in which a player can play a game in an advantageous state.

  In addition, as a state in which the player is advantageous, the second prize member 19500 is located at a lower position, is separated from the game nail YK driven into the first prize member 2400, and a game ball flowing down the game area is provided. A state in which the first winning port 64 is won without being disturbed by the gaming nail YK is exemplified.

  Further, when the second winning member 19500 is displaced downward, the metal body 19343 of the extending portion 19340 connected to the second winning member 19500 is moved downward, and is disposed inside the opening of the sensor device SE. You. Since the metal body 19343 is formed from a material that can be detected by the sensor device SE, when the second winning member 19500 is forgotten to return to the normal position (the position shown in FIG. 45) after the first winning member 2400 is replaced. , A state where the sensor device SE can detect the metal body 19343 can be formed. Therefore, the pachinko machine 10 monitors the detection state of the sensor device SE, and can detect a state in which the second winning member 19500 has been forgotten to be returned to the predetermined position if the detection is continued for a predetermined time or more. Thereby, the pachinko machine 10 can notify the clerk of the abnormal state (for example, abnormal sound or special light emission).

  Therefore, when the second winning member 19500 is arranged at the allowable position, the metal body 19343 is arranged at a position that can be detected by the sensor device SE. Therefore, the detection state (for example, waveform) of the sensor device SE is monitored. , It can be detected that the second winning member 19500 remains in the allowed position (that is, the second winning member 19500 has forgotten to return to the restricted position). In other words, the time during which the sensor device SE is turned on (or off) when the ball passes is made relatively short, while the sensor device is kept in the state where the second winning member 19500 is arranged at the allowable position. Since the time during which the SE is turned on (or off) is continued, when the sensor device SE is turned on (or off) for more than a predetermined time (threshold), the second winning member 19500 is arranged at the allowable position. It can be judged that it is in the state as it is.

  This can prevent the second winning member 19500 from being returned to the normal position after the first winning member 2400 is replaced. In addition, even when the countersunk screw N1 is loosened during the game and the second winning member 19500 is displaced downward, it is possible to notify the clerk. Therefore, the player does not notice that an abnormal state has occurred. Even if you do not, you can inform the clerk. Therefore, when the countersunk screw N1 is loosened and the second winning member 19500 is at an abnormal position, it is possible to prevent the player from continuing to play the game, thereby preventing the player from being disadvantaged.

  Further, in a state where the detecting portion is formed of a metal material and the second winning member 19500 is arranged at the regulation position, part of the inner wall of the passage through which the game ball passes is formed by the metal body 19343, so that the durability of the passage is improved. Performance can be improved.

  A part of the second passage in the first passage and the second passage bent downstream of the first passage (a game ball flowing down from the first passage collides). Site) is preferably formed of the metal body 193943. This is because a portion that is likely to be damaged can be reinforced and the durability can be effectively improved.

  Next, the second winning member 20500 in the twentieth embodiment will be described with reference to FIGS. In the second embodiment, the case where the first winning member 2400 and the second winning member 2500 are separately removed has been described. However, in the twentieth embodiment, the first winning member 20400 and the second winning member 20500 are simultaneously removed. It is. The same parts as those in the above-described embodiments are denoted by the same reference numerals, and description thereof will be omitted.

  FIG. 47A is a front view of the game board 13 in the twentieth embodiment, and FIG. 47B is a cross-sectional view of the game board 13 along the line XLVIIb-XLVIIb in FIG. FIG. 48 is an exploded perspective front view of the game board 13. FIG. 48 shows a state in which the center frame 86 has been removed.

  As shown in FIGS. 47 and 48, the winning opening unit 20300 in the twentieth embodiment includes a first winning member 20400 disposed inside the recessed portion 2060c of the base plate 60, and a first winning member 20400 and a first winning member 20400. The second winning member 20500 is provided on the front side of the base plate 60 (the lower side in FIG. 47B).

  The first winning member 20400 includes a main body 20410 formed of a rectangular plate-like body in a front view, a bulging portion 2420 bulging from the rear side (the upper side in FIG. 47B) of the main body 20410, and a main body. It is mainly provided with a game nail YK driven from the 20410 side (front side).

  The main body part 20410 and the bulging part 2420 are provided with concave portions 20432 that are recessed upward from below at substantially the center in the left-right direction (left-right direction in FIG. 47B). A through hole 2413 through which a flathead screw N2 for fastening the first winning member 20400 to the base plate 60 is formed.

  The concave portion 20432 is formed to be larger than the left-right direction (the left-right direction in FIG. 47 (b)) dimension of the passage forming member 330 of the second winning member 20500 described later, and extends from the front side to the back side of the first winning member 20400. It is formed continuously. Thus, when the second winning member 20500 is disposed in front of the first winning member 20400, the passage forming member 330 can be disposed by being inserted inside the recess 20432.

  In addition, since the concave portion 20432 is formed by opening the lower portion, by passing through the open portion, the concave portion 20432 is integrated with the base plate 60 (that is, the concave portion 20432 and the later-described engaging portion 20513 are engaged). The operation of disassembling the first winning member 20400 and the second winning member 20500 removed by the above can be easily performed.

  The second winning member 20500 includes a base member 20510 formed of a rhombic plate-like body when viewed from the front, a ball winning member 320 protrudingly formed on the front side (the lower side in FIG. 47B) of the base member 2510, It is formed mainly with a passage forming member 330 located on the opposite side of the ball winning member 320 with the base member 2510 interposed therebetween.

  The base member 2510 is formed with an engagement portion 20513 protruding rearward from left and right edges on the upper end side of the opening 311. The engagement portions 20513 are formed above both ends of the passage forming member 330 in the left-right direction (the left-right direction in FIG. 47B). The engaging portion 20513 is formed so as to protrude from the rear surface of the base plate 2510 toward the rear surface (upper side in FIG. 47B), and has a protruding tip bent outward in the left-right direction.

  Also, the protrusion L13 (see FIG. 47 (b)) of the engaging portion 20513 protruding to the rear side is set to be substantially the same as the thickness dimension of the first winning member 20500 in the front-rear direction (vertical direction in FIG. 47 (b)). You. The engaging portion 20513 has a distance L14 (see FIG. 47B) in the left-right direction on the base end side (the side of the base member 20510 of the second winning member 20500), which is the concave portion 20432 of the first winning member 20400 described above. And the distance L15 (see FIG. 47 (b)) in the left-right direction on the bent front end side is formed to be larger than the length of the recess 20432 in the left-right direction. You. Thereby, the second winning member 20500 can be engaged with the first winning member 20400.

  Further, the engaging portion 20513 includes an elastic piece 20513b formed so as to be elastically deformable, a claw portion 20513c protruding from the elastic piece, and an inclined surface 20513a inclined from the back side to the front side toward the bent end. Are formed. Thereby, by making the inclined surface 20513a of the engaging portion 20513 abut against the inner wall of the concave portion 20432, the second winning member 20500 can be arranged (inserted) from the front side of the first winning member 20400, and can be disposed on the back surface. By reaching, the engaging portion 20513 can be engaged with the first winning member 20400.

  According to the winning opening unit 20300 configured as described above, when the two gaming nails YK of the first winning member 20300 are broken to replace the first winning member 20400, the second winning member 20500 is connected to the base plate 60. By removing the first winning member 20400 from the base plate 60, the first winning member 20400 can be removed from the base plate 60.

  Here, a gaming machine including a first gaming board member (base plate 60) and a second gaming board member fastened and fixed to the first gaming board member and forming a gaming board together with the first gaming board member is known. ing. According to such a gaming machine, the second gaming board member can be attached to and detached from the first gaming board member. Therefore, if a failure or breakage occurs in the second gaming board member, only the second gaming board member is replaced. Thus, it is not necessary to replace the entire game board. However, the conventional gaming machine described above has a problem that the second gaming board member is difficult to remove from the first gaming board member. For example, in the second game board member where nails are planted, the worker can remove the second game board member from the game board by gripping the nail, but when the nail is broken, Since there is no portion to be gripped by the second game board member, removal becomes difficult. Such a problem is particularly remarkable when the second game board member is embedded in the first game board member so that the game surfaces of the second game board member and the first game board member are flush with each other. Becomes

  On the other hand, in the twentieth embodiment, when at least the countersunk screw N2 is removed, the first winning member 20400 is formed so that the operator can directly or indirectly grip the first winning member 20400. It can be easily removed.

  That is, in the twentieth embodiment, the first prize member 20400 and the second prize member 20500 are arranged in a state of being engaged by the engagement portion 20513, and therefore, both of the two game nails YK of the first prize member 20400 are provided. In the case of breaking, by removing the countersunk screws N1 and N2, holding the second winning member 20500 disposed on the front side from the base plate 60 with a finger, and pulling out the front side, the first winning member is obtained. 20400 can be removed from base plate 60 at the same time. As a result, replacement of the first winning member 20400 can be simplified.

  Further, the engaging portion 20513 includes an elastic piece 205513b formed to be elastically deformable, and a claw 20513c protruding from the elastic piece, and the claw 20513c is formed to be engageable with the recess 20432. Therefore, even when the first winning member 20400 and the second winning member 20500 are separately mounted, the engaging portion 20513 and the concave portion 20432 can be engaged by utilizing the elastic deformation of the elastic elastic piece 20513b. . Therefore, there is no need to attach the first winning member 20400 or the second winning member 20500 to the base plate 60 because the first winning member 20400 or the second winning member 20500 does not need to be attached to the base plate 60 in an integrated state. Performance can be improved.

  When the first winning member 20400 needs to be removed, the first winning member 20400 can be removed from the base plate 60 by holding and pulling out the second winning member 20500 without holding the first winning member 20400 with a finger. Since it can be removed, it is possible to prevent the game nail YK of the first winning member 20400 from being held by the operator. As described above, since the game nail YK is a portion adjusted to a size that allows a game ball to be inserted between the two, the game nail YK is held with a finger when the first winning member 20400 is removed. In other words, the adjustment may be out of order (the gaming nail YK may bend).

  On the other hand, in the winning opening unit 20300, since the second winning member 20500 and the first winning member 20400 can be removed at the same time, the first winning member 20400 can be removed from the base plate 60 without holding the gaming nail YK. Can be removed. Therefore, when the first winning member 20400 is removed, it is possible to prevent the game nail YK from being misaligned (the game nail YK is bent).

  Next, a base plate 60 according to a twenty-first embodiment will be described with reference to FIGS. In the second embodiment, the case where the first winning member 2400 is directly provided on the base plate 60 has been described. However, the first winning member 2400 of the twenty-first embodiment has the elastic member 21510 between the first winning member 2400 and the base plate 60. Intervened. The same parts as those in the above-described embodiments are denoted by the same reference numerals, and description thereof will be omitted.

  FIG. 49 (a) is a front view of the game board 13 in the twenty-first embodiment, and FIG. 49 (b) is a cross-sectional view of the game board 13 along the line XLIXb-XLIXb in FIG. 49 (a). FIGS. 50 (a) and 50 (b) are cross-sectional views of the game board 13 taken along the line La-La in FIG. 49 (a). 49 and 50 show a state in which the second winning member 2500 has been removed.

  As shown in FIG. 49 and FIG. 50, the base plate 60 in the twenty-first embodiment is arranged such that the recessed portion 2060c is positioned from the front side (front side in FIG. 49 (a)) toward the center opening (center frame 86) side. A concave portion 21060d that is recessed toward the side is formed.

  The outer shape of the recessed portion 21060d when viewed from the front is substantially the same as the outer shape of the first winning member 2400. Thus, the first winning member 2400 can be inserted and disposed inside the recess 21060d. The recess 21060d mainly includes an annular projection 2060d1 protruding to the front and a curved portion 21060d9 recessed in a semicircular shape from the front to the back.

  The curved portion 21060d9 is a concave portion into which an elastic member 21510 described later is inserted inside, and is formed to be curved in the left-right direction (the left-right direction in FIG. 50A). Further, the curved portion 21060d9 is set such that the maximum recessed distance to the back side is larger than the radius of an elastic member 21510 described later. Further, the curved portion 21060d9 is formed such that upper and lower ends (upper and lower ends in FIG. 49A) (inner walls) are planes parallel to the horizontal direction.

  The elastic member 21510 is formed in a cylindrical shape from a rubber material. The elastic member 21510 has an axial dimension smaller than the vertical dimension of the curved portion 21060d9. Therefore, the elastic member 21510 can be disposed inside the curved portion 21060d9 in a vertical posture.

  Further, as described above, the elastic member 21510 is formed to have a radius smaller than the maximum recessed distance of the curved portion 21060d9 on the back side. Therefore, when the elastic member 21510 is disposed inside the curved portion 21060d9, the elastic member 21510 can be disposed by being placed on the lower surface (lower wall surface) of the curved portion 21060d9. Therefore, the elastic member 21510 can be easily arranged, and the elastic member 21510 can be made independent until the main body 2410 is arranged.

  Further, the elastic member 21510 is formed so that its diameter is larger than the maximum recessed distance of the curved portion 21060d9 to the back side. Accordingly, when the elastic member 21510 is provided inside the curved portion 21060d9, a part of the elastic member 21510 can be projected forward of the recess 2060d.

  The first winning member 2300 is disposed inside the recessed portion 2060c from the front side in a state where the elastic member 21510 is disposed on the base plate 60. Accordingly, the first winning member 2300 can be disposed on the base plate 60 while the elastic member 21510 is elastically compressed and deformed.

  According to the gaming board 13 configured as described above, when the first winning member 2400 is disposed on the base plate 60 and the flathead screw N2 is fastened and fixed, the elastic member 21510 is formed by the main body 2410 of the first winning member 2400. Is pressed and elastically deformed. Therefore, when replacing the first winning member 2400, when the countersunk screw N2 for fastening the first winning member 2400 is removed, the main body 2410 of the first winning member 2400 is pushed forward by the elastic recovery force of the elastic member 21510. It is. Therefore, the first winning member 2400 can be made to protrude from the base plate 60 to form a step between them. Therefore, since the operator can directly or indirectly hold the step, the first winning member 2400 can be easily removed from the base plate 60.

  When the two game nails YK of the first winning member 2400 are both broken and the first winning member 2400 is to be detached from the base plate 60, the countersunk screw N2 is removed so that the first winning member 2400 is pushed forward. As a result, a portion where the first winning member 2400 is grasped by a finger can be formed. As a result, the first winning member 2400 can be easily removed from the base plate 60.

  Further, when the first winning member 2400 is removed, a portion other than the gaming nail YK can be grasped, so that when the first winning member 2400 is removed, the bending of the gaming nail YK can be suppressed.

  Next, with reference to FIGS. 51 and 52, a winning opening unit 22300 in the twenty-second embodiment will be described. In the second embodiment, the case where the front surface of the main body 2410 is disposed on the same plane as the front surface of the base plate 60 has been described. However, in the twenty-third embodiment, the protruding portion 22433 protruding to the front surface side is provided on the main body 2410. Is formed.

  FIG. 51 (a) is an exploded perspective view of the winning opening unit 22300 in the twenty-second embodiment, and FIG. 51 (b) is a front view of the game board 13. FIG. 52 (a) is a cross-sectional view of the game board 13 along the line LIIa-LIIa in FIG. 51 (b), and FIG. 52 (b) is a cross-section of the game board 13 along the line LIIb-LIIb in FIG. 52 (a). FIG. In FIG. 51 (b), FIG. 52 (a) and FIG. 52 (b), the second winning member 22300 is seen transparently, and the outer shape is shown by a chain line.

  As shown in FIGS. 51 and 52, the winning opening unit 22300 in the twenty-second embodiment includes a first winning member 22400 disposed inside the recessed portion 2060c of the base plate 60, and a first winning member 22400 and a first winning member 22400. The second winning member 22500 is provided on the front side of the base plate 60 (the right side in FIG. 47A).

  The first winning member 22400 includes a main body portion 22410 formed of a rectangular plate-like body in a front view, a bulging portion 2420 bulging from the back side of the main body portion 22410 (the left side in FIG. 52A), and a main body portion. It is mainly provided with a game nail YK driven from the side 22410 (front side).

  The first winning member 22400 is located below the gaming nail YK, and has an opening 22434 that opens in the front-rear direction to have a shape larger than the outer diameter of the game ball, and protrudes forward from the lower end of the inner edge of the opening 22434. It mainly includes a projecting portion 22433 and through holes 2413 formed at both ends in the left-right direction of the main body portion 22410 and through which flat head screws N2 for fastening the first winning member 22400 to the base plate 60 are inserted.

  The opening 22434 is formed on the back side of an opening 311 of a second winning member 22,500 described later, and allows the game balls flowing into the first winning opening 64 to pass through the opening 22434 so that the back surface of the base plate 60 is formed. You can send the ball to the side.

  The protruding portion 22433 is formed so as to protrude from the opening portion 22434 to the front side, and the upper surface thereof is formed to be inclined downward toward the back side. Further, the projecting portion 22433 has a projecting dimension set to a size that abuts against the rear side of the front surface 322 of the ball winning member 320.

  The second winning member 22500 mainly includes a base member 2510 formed of a rhombic plate in a front view, and a ball winning member 320 protruding from the front side (the right side in FIG. 52A) of the base member 2510. It is formed in preparation for.

That is, the groove 22322a is formed on the front side of the above-described protrusion 22433, and the outer shape in a front view is set to be substantially the same as the outer shape of the protrusion 22433. Accordingly, when the second winning member 22500 is disposed on the front side of the first winning member 22400, the second winning member 22500 can be positioned with respect to the first winning member 22400 by the protrusion 22433 and the groove 22321a.

  Therefore, in the gaming state, the protruding portion 22433 is hidden from the player by the second winning member 22500 to improve the appearance, and in a state where the second winning member 22500 is removed, the worker can grip the protruding portion 22433. The components can be easily removed from the game board.

  Further, as described above, since the upper surface of the protruding portion 22433 is formed to be inclined downward toward the rear side, the game ball that has flowed into the first winning opening 64 is placed on the upper surface and rolls to the rear side. Can be done. Therefore, it is not necessary to separately provide the groove portion 22321a and the protruding portion 22433, and it can be used as a portion for forming a passage, so that the product cost can be reduced accordingly.

  According to the ball winning unit 22300 formed as described above, when both of the gaming nails YK of the first winning member 22400 are broken and the first winning member 22400 is replaced, the first winning member 22400 is removed from the base plate 60. Can be easily removed.

  More specifically, since the first winning member 22400 is disposed on the same plane as the front surface of the base plate 60, a portion for holding the first winning member 22400 with a finger when both of the gaming nails YK are removed. Disappears. Therefore, it is difficult to remove the first winning member 22400 from the base plate 60 when both of the gaming nails YK are broken.

  On the other hand, in the twenty-second embodiment, since the first winning member 22400 is formed with the protruding portion 22433 projecting to the front side, when both of the gaming nails YK of the first winning member 22400 are broken, By removing the second winning member 22500, the protruding portion 22433 can protrude from the front surface of the base plate 60. Therefore, the first winning member 22400 can be removed from the base plate 60 while holding the protrusion 22433 with a finger. As a result, replacement of the first winning member 22400 can be simplified.

  Further, when the first winning member 22400 is removed, a portion other than the gaming nail YK can be grasped, so that when the first winning member 22400 is removed, the bending of the gaming nail YK can be suppressed.

  In addition, as described above, the protrusion 22433 can be positioned (fitted) into the groove 22321a, thereby positioning the second winning member 22400, and playing the game ball flowing into the first winning opening 64 on the back surface. It can be used as a rolling surface to roll to the side. Accordingly, since it is not necessary to newly form a portion for positioning the second winning member 22400 and a portion for rolling the game ball, the manufacturing cost of the winning opening unit 22300 can be reduced.

  Here, in the present embodiment, since the relative position between the game nail YK implanted in the first winning member 22400 and the protrusion 22433 is constant, a stable game can be provided to the player. That is, in the conventional product in which the protruding portion 22433 is formed integrally with the winning opening unit 22300, the mounting position of the winning opening unit 22300 with respect to the first winning member 22400 due to the dimensional tolerance of each part and the working tolerance at the time of the mounting operation. , The relative position between the protruding portion 22433 and the gaming nail YK is not constant. Therefore, depending on their positional relationship, even if the ball passes between the pair of gaming nails YK of the first winning member 22400 and enters the first winning opening 64, it rebounds depending on the collision position with the protrusion 22433. As a result, the player sometimes jumps out of the first winning opening 64.

  On the other hand, in the present embodiment, since the protrusion 22433 is provided (integrally formed) on the first winning member 22400, the relative position between the game nail YK implanted on the first winning member 22400 and the protrusion 22433. The position can be fixed. Therefore, the above-described rebound can be suppressed, and a stable game can be provided to the player.

  The large diameter portion 23435a is a through hole into which a head 23451 of a holding member 23450 described later is inserted, and is formed to have an inner diameter larger than the outer diameter of the head 23451. The small diameter portion 23435b is a through hole through which a shaft portion 23452 of a holding member 23450 described later is inserted, and is formed to have an inner diameter with a large outer diameter prediction of the shaft portion 23452.

  The holding member 23450 has a head 23451 formed in a columnar shape, and a shaft portion formed coaxially with the head 23451 and formed in a column shape having an outer diameter smaller than the outer diameter of the head 23451. 234542 and a groove 23453 recessed on the back side of the shaft portion 23452.

  The head 23451 is formed smaller in the axial direction (length in the left-right direction in FIG. 54A) than the axial length of the large-diameter portion 23435a. Further, the outer diameter is formed larger than the coil spring SP disposed around the shaft portion 23452. Thereby, when the head 23451 is inserted into the second through hole 23435, the coil spring SP can be prevented from coming off to the front side.

  As described above, the shaft portion 23452 is a member that is inserted into the second through hole 23435 and slides in the front-rear direction inside the small diameter portion 23435b, and is formed longer in the axial direction than the axial length of the second through hole 23435. Is done.

  The groove 23453 is a groove in which the E-ring 23454 is mounted, and is formed over the circumferential direction of the shaft 23452 with a width slightly larger than the thickness of the E-ring 23454. The groove portion 23453 is formed on the back side of the shaft portion 23452, and the E-ring 23454 is attached in a state where the groove portion 23453 protrudes from the back side of the second through hole 23453 (the left side in FIG. 54A).

  The E-ring 23454 has a larger outer diameter than the small-diameter portion 23435b of the second through hole 23453. Thereby, the state where the holding member 23450 is disposed inside the second through hole 23435 can be maintained. A coil spring SP is provided around the shaft portion 23452. Therefore, the head 23451 is held in a state of being urged to the front side (the right side in FIG. 54) by the elastic recovery force of the coil spring SP.

  Therefore, the first winning member 23400 is formed at a position where the axis of the second through hole 23435 overlaps the second winning member 2500 in the front-rear direction, so that the second winning member 2500 is fastened and fixed to the base plate 60. The head 23451 of the holding member 23450 is pressed to the back by the base member 2510 of the second winning member 2500. As a result, the coil spring SP is contracted, and the head 23451 of the holding member 23450 is placed inside the large diameter portion 23435a.

  On the other hand, as shown in FIG. 54B, when the second winning member 2500 is detached from the base plate 60, the head 23451 of the holding member 23450 is pushed out to the front side by the elastic recovery force of the coil spring SP. Thereby, the holding member 23450 can be displaced to the front side.

  Therefore, when the two gaming nails YK of the first winning member 23400 are broken and the first winning member 23400 is replaced, the first nail member 23400 can be easily removed from the base plate 60.

  More specifically, since the first winning member 23400 is disposed on the same plane as the front surface of the base plate 60, a portion for holding the first winning member 23400 with a finger when both of the gaming nails YK are removed. Disappears. Therefore, it is difficult to remove the first winning member 23400 from the base plate 60 when both of the gaming nails YK are broken.

  On the other hand, in the twenty-third embodiment, a holding member 23450 provided so as to be able to protrude and retract from the first winning member 23400, a coil spring SP for urging the holding member 23450 in the protruding direction, and a base member 60 are provided. Since the second winning member 2500 is provided at a position where the holding member 23450 of the first winning member 23400 is immersed, the holding member 23450 is moved by the second winning member 2500 in the gaming state. In a state in which the second winning member 2500 is removed while the appearance is improved while being hidden from the player, the holding member 23450 can be gripped by the worker so that the first winning member 23400 can be easily removed from the base plate 60. it can.

  Also, since the direction in which the second winning member 2500 is fastened to the game board is set in a direction parallel to the direction in which the holding member 23450 emerges, the holding member 23450 is immersed while the second winning member 2500 is fastened and fixed to the game board. Can be done. That is, since it is not necessary to separately perform the work process of immersing the holding member 23450 and the work process of fastening and fixing the second winning member 2500 to the game board, the man-hour can be reduced, and the first winning member 23400 and the The workability of the work of attaching the second winning member 2500 to the game board can be improved.

  Further, when removing the first winning member 23400, a portion other than the gaming nail YK can be grasped, so that when removing the first winning member 23400, the bending of the gaming nail YK can be suppressed.

  In addition, since the holding member 23450 has a head 23451 having a larger outer diameter than the shaft portion 23452, the head 23451 can be easily hooked on a finger. Therefore, the first winning member 23400 can be easily removed from the base plate 60 accordingly.

  Next, a first winning member 24400 in the twenty-fourth embodiment will be described with reference to FIG. In the second embodiment, when removing the first winning member 24400, the case where the finger can be locked on the back surface of the first winning member 24400 has been described. However, the first winning member 24400 of the twenty-fourth embodiment is different from the first embodiment. , Is formed so that a finger can be locked on the inner wall of the opening 24434. The same parts as those in the above-described embodiments are denoted by the same reference numerals, and description thereof will be omitted.

  FIG. 55 (a) is a front view of the game board 13 in the twenty-fourth embodiment, and FIG. 55 (b) is a cross-sectional view of the game board 13 along the line LVb-LVb in FIG. 55 (a). In FIG. 55 (a) and FIG. 55 (b), the second winning member 2500 is seen transparently, and the outer shape is shown by a broken line.

  As shown in FIG. 55, the first winning member 24400 in the twenty-fourth embodiment includes a main body 24410 formed of a rectangular plate-shaped body as viewed from the front, and a rear side of the main body 24410 (the left side in FIG. 55B). It is formed mainly with a bulging portion 2420 bulging out of the main body and a game nail YK driven from the main body portion 24410 side (front side).

  The main body portion 24410 is located below the gaming nail YK, and has an opening portion 24434 that opens in the front-rear direction (the left-right direction in FIG. 55) in a shape larger than the outer diameter of the game ball, and downward from the upper end of the inner edge of the opening portion 24434. It mainly includes a protruding wall 24434a and a through hole 2413 formed at both ends in the left-right direction and through which a countersunk screw N2 for fastening the first winning member 24400 to the base plate 60 is inserted.

  The opening 24434 is formed on the back side of the opening 311 of the second winning member 2500, and the game ball flowing into the first winning opening 64 is inserted through the opening 24434 and the back side of the base plate 60. Can be sent to

  The protruding wall 24434a is a wall formed to protrude downward from the front side of the upper end of the inner edge of the opening 24434. Since the projecting wall 24434a with the step surface facing the back side of the base plate 60 is formed on the inner wall of the opening 24334, the first winning member 24400 can be pulled out of the base plate 60 using the step surface. That is, there is no need to insert the finger into the passage until the finger reaches the back of the first winning member 24400, and it is not necessary to lock the finger on the back of the first winning member 24400, and the finger is engaged on the step surface at a relatively shallow position. The first winning member 24400 can be easily removed from the base plate 60 because it can be stopped.

  In addition, the first winning member 24400 has a notch 24436 formed on the rear side of the lower end portion thereof, which is formed by notching the entire area of the first winning member 24400 in the width direction (the left-right direction in FIG. 55A). The notch portion 24436 is formed to be inclined upward toward the rear side. Accordingly, when the first winning member 24400 is detached from the base plate 60 by hooking a finger on the protruding wall 24434a, the opening portion is used to pull out the first winning member 24400 from the base plate 60 using the notch portion 24436. A mode in which the first winning member 24400 is rotated with the outer side surface (the upper surface in FIG. 55B) of the first winning member 24400 located on the inner wall side where the step surface of 24434 is formed can be formed. Therefore, the first winning member 24400 can be easily removed (pulled out) from the base plate 60.

  Next, the fastening direction of the first winning member 25400 to the base plate 60 in the twenty-fifth embodiment will be described with reference to FIGS. In the second embodiment, the case where the countersunk screw N2 is screwed into the annular projection 2060d1 formed on the base plate 60 has been described. However, in the 25th embodiment, the countersunk screw N2 is located on the back side of the first winning member 25400. It is screwed into the fastening member 25470 provided. The same parts as those in the above-described embodiments are denoted by the same reference numerals, and description thereof will be omitted.

  FIG. 56 is an exploded perspective front view of the game board 13 in the twenty-fifth embodiment. FIG. 57 (a) is a front view of the game board 13, and FIGS. 57 (b) and 57 (c) are cross-sectional views of the game board 13 along the line LVII-LVII in FIG. 57 (a). FIG. 57 (b) shows a state before the game nail YK is driven into the bulging portion 25420, and FIG. 57 (c) shows a state after the game nail YK is driven into the bulging portion 25420. Illustrated. 56 and 57 show a state in which the second winning member 2500 has been removed from the game board 13.

  As shown in FIGS. 56 and 57, the base plate 60 in the twenty-fifth embodiment is arranged such that the recessed portion 2060c surrounds the center opening (center frame 86) side from the rear side (the upper side in FIG. 56B) to the front side. (FIG. 56 (b), lower side).

  The outer shape of the recess 25060 in rear view is substantially the same as the outer shape of the first winning member 25060. Thus, the first winning member 25400 can be provided inside the recess 25060d. In addition, an insertion hole 25060d3 penetrating in the front-rear direction is formed in the recess 25060d.

  The insertion hole 25060d3 is formed in a circular shape in a front view, and is formed coaxially with the insertion hole 25418 of the first winning member 25400 in a state where a first winning member 25400 described later is disposed on the base plate 60. Further, the insertion hole 25418 is formed such that the front side is enlarged to a size that can accommodate the head of the countersunk screw N2.

  The first winning member 25400 is formed by a main body 25410 formed from a horizontally elongated rectangular plate, a bulge 25420 bulging from the front side of the main body 25410, and a first prize member 25400 driven from the bulge 25420. It is mainly provided with a game nail YK.

  The bulging portion 25420 is formed at a substantially central position in the longitudinal direction (the left-right direction in FIG. 57B) of the main body portion 25410, and has an outer dimension shorter than the main body portion 257410 in the longitudinal direction of the main body portion 25410. The main body 25410 has insertion holes 25410 formed at both ends in the longitudinal direction so as to penetrate in the front-rear direction (vertical direction in FIG. 57B).

  The insertion hole 25418 is a hole through which the tip of the countersunk screw N2 for fastening and fixing the first winning member 25400 is inserted, and has an inner diameter larger than the outer diameter of the tip end (shaft) of the countersunk screw N2. The insertion hole 25418 has its axis formed coaxially with the axis of the insertion hole 25060d3 formed in the base plate 60. This allows the flathead screw N2 to be inserted through the insertion hole 25418 after the insertion hole 25060d3 of the base plate 60 is inserted.

  The fastening member 25470 is formed of an iron material, and is also formed in a horizontally long rectangular plate shape in a front view. The fastening member 25470 has its longitudinal dimension L16 (see FIG. 57 (b)) set to be larger than the longitudinal dimension L17 (see FIG. 57 (b)) of the first winning member 25400, and has a longitudinal central position. The main body 25400 is provided at the same position in the longitudinal center and the front-rear direction (FIG. 57).

  In addition, the fastening member 25470 has an intermediate position in the short direction (the vertical direction in FIG. 57 (a)) set on the back side of the connection portion between the game nail YK and the first winning member 25400, and at both left and right ends. A fastening hole 25471 penetrating in the front-rear direction is provided. It is arranged on the back side of the connection portion between the game nail YK and the first winning member 25400. That is, the fastening member 25470 can be positioned on an extension of the game nail YK in the planting direction. Therefore, since the support rigidity of the first winning member 25400 can be effectively increased while suppressing the area of the fastening member 25470, the game nail YK is planted on the front surface of the first winning member 25400 while suppressing the product cost. At the time of installation, the first winning member 25400 can be prevented from being damaged such as a crack.

  In the fastening hole 25471, a female screw into which the countersunk screw N2 can be screwed is formed inside. The fastening hole 25471 has its axis formed coaxially with the above-described insertion hole 25418 of the first winning member 25400 and the insertion hole 254060d3. Thereby, the countersunk screw N2 inserted through the insertion holes 25400d3 and 25418 can be screwed into the fastening hole 25471 of the fastening member 25470.

  Therefore, in a state where the first winning member 25400 is disposed on the base plate 60, the countersunk screw N2 is inserted from the front side of the base plate 60 through the insertion holes 25060d3 and 25418, and screwed into the fastening holes 25471. The first winning member 25400 can be fastened and fixed to the base plate 60.

  Here, a first game board member (base plate 60) and a second game board member disposed on the first game board member and forming a game board with the first game board member are provided, and the second game board is provided. 2. Description of the Related Art A gaming machine in which a nail (game nail YK) is implanted in a member is known. According to such a gaming machine, since the second game board member can be attached to and detached from the game board, for example, when the nail of the second game board member is broken, only the second game board member is replaced, and the game is played. It is not necessary to replace the entire board. However, the conventional gaming machine described above has a problem that the workability for implanting nails is poor. That is, since a step of implanting a nail in the second game board member is required separately from a step of implanting a nail in the first game board member, the number of steps increases accordingly. Further, since the second game board member is relatively small, in order to implant nails within a predetermined tolerance in the second game board member, the holding accuracy of the second game board member is increased and the speed of the planting operation is increased. Is required, and the number of man-hours is increased as compared with the case where a nail is planted on a relatively large game board.

  On the other hand, according to the twenty-fifth embodiment, since the first winning member 25400 pressed from the front side of the base plate 60 is formed so as to be supported, the first winning member 25400 is disposed on the base plate 60. Thus, the game nail YK can be planted in the first winning member 25400. Therefore, the workability of implanting the game nail YK in the first winning member 25400 can be improved.

  That is, a pair of countersunk screws N2 and a fastening member 25470 formed of a material having a higher rigidity than the base plate 60 and the first winning member 25400 are formed with fastening holes 25471 into which the pair of countersunk screws N2 are screwed. The countersunk screw N2, which is inserted through the through hole 2560d3 of the base plate 60 and protrudes to the rear side of the first winning member 25400, is screwed into the female screw of the fastening member 25470. In a state where 25400 is provided, the first winning member 25400 can be supported by the fastening member 25400 from the back side. Therefore, when a game nail is planted on the game surface of the first winning member 25400, it is possible to prevent the first winning member 25400 from being damaged or the like.

  In this case, as described above, the fastening member 25470 has a longitudinal dimension L16 smaller than the longitudinal dimension L17 of the main body 25410, and is disposed at the left-right central position of the first winning member 25400. Therefore, it is possible to prevent the fastening member 25470 from riding on the rear side of the base plate 60. Therefore, the fastening member 25470 can be easily brought into close contact with the back surface of the first winning member 25400, and the rigidity of the first winning member 25400 supported by the fastening member 25470 can be increased. As a result, when implanting the game nail YK on the game surface of the first winning member 25400, it is possible to prevent the first winning member 25400 from being damaged such as a crack.

  Next, a first winning member 26400 in the twenty-sixth embodiment will be described with reference to FIGS. In the second embodiment, the case where the side surfaces at both ends in the left-right direction of the bulging portion 2420 are formed parallel to the front-rear direction (the vertical direction in FIG. 15C), but in the 26th embodiment, the bulging portion 26420 is formed. Are inclined toward the center in the left-right direction toward the back side. The same parts as those in the above-described embodiments are denoted by the same reference numerals, and description thereof will be omitted.

  FIG. 58 is an exploded perspective front view of the game board 13 in the twenty-sixth embodiment, and FIGS. 59 (a) and 59 (b) are cross-sectional views of the game board 13. FIGS. 59A and 59B correspond to the cross-sectional view of FIG. FIG. 59A shows a state before the game nail YK is driven into the main body 2410. Further, FIGS. 58 and 59 show a state in which the second winning member 2500 has been removed from the game board 13.

  As shown in FIGS. 58 and 59, the base plate 60 in the twenty-sixth embodiment has a concave portion 26060 c formed continuously below the center opening of the base plate 60 to which the center frame 86 is attached. The first winning member 26400 is partially inserted into the recessed portion 26060c, and is fixed from the front side of the base plate 60 with the countersunk screw N2.

  The recessed portion 26060c is formed with an inclined surface 26060c1 whose inner end surface is inclined toward the center in the left-right direction toward the back side. The inclined surface 26060c1 is formed to extend vertically. The length of the inclined surface 26060c1 in the front-rear direction is set smaller than the length in the front-rear direction of a bulging portion 26420 of a first winning member 26400 described later.

  The first winning member 25400 includes a main body portion 2410 formed of a plate-like body having a horizontally long rectangular shape in front view, a bulging portion 26420 bulging out from the rear side (FIG. 59 (upper)) of the main body portion 2410, and a main body portion. It is formed mainly with a game nail YK driven from the 2410 side.

  In the main body 2410, through holes 26413 penetrating in the front-rear direction are formed at both left and right ends. The through hole 26413 is formed coaxially with the fastening hole 26060d4 formed in the base plate 60. With the first winning member 26400 arranged on the base plate 60, the countersunk screw N2 is inserted into the through hole 26413 from the front side. The first winning member 26400 can be fastened and fixed to the base plate 60 by being inserted and screwed into the fastening hole 26060d4.

  The bulging portion 26420 is formed at a substantially central position in the longitudinal direction of the main body portion 2410 (the left-right direction in FIG. 59B), and is formed to have a dimension shorter than the main body portion 2410 in the longitudinal direction of the main body portion 2410.

  The bulging portion 26420 has contact surfaces 26424 that are located at both ends in the left-right direction (the left-right direction in FIG. 59A) of the bulging portion 26420 and are formed to be inclined inward in the left-right direction toward the back side. . The contact surface 26424 has an inclination angle substantially equal to the inclination angle described above. Further, the size of the bulging portion 26420 on the main body portion 2410 side (front side) in the left-right direction (the left-right direction in FIG. 59 (a)) is determined by the left and right sides of the inclined surface 26060c1 of the base plate 60 on the front side (boundary with the recess 2060d) The dimension is set to be larger than the direction dimension. Accordingly, when the first winning member 26400 is disposed on the base plate 60, the contact surface 26424 is brought into contact with the inclined surface 26060c1, and a gap is formed between the back surface of the main body 2410 and the front surface of the recess 2060d. Can be provided.

  When the first winning member 26400 is disposed on the base plate 60 from the front side, the contact surface 26424 of the first winning member 26400 is displaced rearward while being in contact with the inclined surface 26060c1. The surface 26424 is guided to the inclined surface 266060c1. Therefore, the positioning of the first winning member 26400 on the base plate 60 can be simplified.

  Further, in a state where the first winning member 26400 is disposed on the base plate 60, the contact surface 26424 and the inclined surface 26060c1 can be brought into contact with each other, so that the first winning member 26400 pressed from the front side can be obtained. Are formed so that the force acting on the base member 60 can be dispersed in a direction orthogonal to the thickness of the base plate 60. Therefore, the workability of implanting the game nail YK in the first winning member 26400 can be improved.

  More specifically, the contact surface 26424 where the first winning member 26400 and the base plate 60 contact each other is formed as an inclined surface 26060c1 that is inclined with respect to the driving direction of the game nail YK. The pressing force when the nail YK is implanted is adjusted by using the inclination (taper angle) of the contact surface 26424 and the inclined surface 26060c1 in the thickness direction of the base plate 60 (vertical direction in FIG. 59A). It can be dispersed in the direction perpendicular to the thickness (the left-right direction in FIG. 59A). As a result, the burden on the base plate 60 can be reduced, and the base plate 60 can be prevented from being damaged such as cracks.

  As described above, the present invention has been described based on the above embodiments. However, the present invention is not limited to the above embodiments, and various modifications and improvements can be made without departing from the spirit of the present invention. Can easily be inferred.

  In each of the above embodiments, a gaming machine may be configured by replacing or combining some or all of one embodiment with some or all of other one or more embodiments.

  In each of the above-described embodiments, the case where the target that is removably provided on the base plate 60 is the winning opening unit 300 or the like, but is not necessarily limited to this, and other members or devices may be used. good. Examples of the other members and devices include a movable accessory, an attacker, and a center frame. Similarly, the case where the game nail YK is implanted or the case where a passage through which the game ball can pass is formed in the first winning member 2400 or the like has been described, but the present invention is not necessarily limited to this. One or both of the gaming nail YK and the passage may be omitted, and another member or device may be provided. Examples of other members and devices include a windmill and a sensor device.

  In each of the above embodiments, the case where the base plate 60 (the first game board component member) is formed from a light-transmissive resin material has been described, but the present invention is not necessarily limited to this. For example, the base member 60 may be formed in a form that does not transmit light by painting or sticking a seal. Further, the base plate 60 may be formed from another material. As another material, wood (for example, plywood represented by plywood) is exemplified. When the base plate 60 is made of wood, it is difficult to secure the fastening strength, and it is not suitable for a plurality of fastenings. Therefore, the configuration in each of the above embodiments is particularly effective. The same applies to the material of the first winning member 2400 and the like (the second game board constituting member).

  In the third embodiment, the case where the head of the countersunk screw N2 for fastening the first winning member 3400 is made visible from the player side is not limited to this. For example, the cover portion 4511 of the second winning member 4500 of the fourth embodiment may be formed in the main body 3510 so that the head of the countersunk screw N2 is hard to be visually recognized by the player.

  In the above-described sixth embodiment, the case where the recessed portion 6060d is recessed on the front surface side (around the recessed portion 2060c) of the base member 60 has been described. However, the present invention is not limited to this, and the recessed portion 6060d is not limited to this. The setting may be omitted. That is, it is only necessary that a surface forming the fastening hole 6060d4 be formed on the lower surface of the concave portion 2060c. Accordingly, the processing cost of the base member 60 can be reduced and the product cost can be reduced because the formation of the recess 6060d can be omitted. At the same time, the outer shape of the first winning member 6400 can be simplified (in the sixth embodiment, a rectangular parallelepiped shape in which the outer shape of the main body portion 6410 and the bulging portion 2420 is the same in a front view). Can be planned.

  In the seventh embodiment, the case where the cross-sectional shape of the through-hole 7060e is circular is described, but the present invention is not necessarily limited to this. For example, a circle, an ellipse, a polygon, or a combination thereof may be used. The through hole 7060e only needs to be formed so that at least the countersunk screw N2 can be inserted, and a part of the peripheral surface may be opened. The open portion may be continuous along the insertion direction of the flathead screw N2, or may be only a part of the insertion direction.

  In the above-described seventh embodiment, the case has been described where the enlarged diameter portion 7060e1 is formed such that the recessed dimension thereof is smaller than the projection dimension of the annular projection 7414. However, the present invention is not necessarily limited to this. For example, the recessed dimension of the enlarged diameter portion 7060e1 may be formed larger than the projected dimension of the annular projection 7414. In this case, in a state where the first winning member 7400 is fastened and fixed to the base plate 60, a state where the front surface of the first winning member 7400 and the back surface of the base plate 60 are in contact can be formed. That is, a state can be formed in which a gap is formed between the protruding tip of the annular projection 7414 and the concave bottom surface of the enlarged diameter portion 7060e1. Therefore, the first winning member 7400 can be firmly fixed to the base plate 60 while securing the contact area.

  In the seventh embodiment, the case where the center frame 86 is provided in the center opening (window portion) of the base plate 60 has been described, but the present invention is not necessarily limited to this.

A gaming machine A1 characterized by being performed.

  Here, there is known a gaming machine including a first gaming board member and a second gaming board member fastened and fixed to the first gaming board member and forming a gaming board together with the first gaming board member (for example, JP-A-2003-310905). An insertion hole is formed in the second game board member, and an internal thread is formed in the first game board member. A screw member inserted into the insertion hole of the second game board member is inserted into a female screw of the first game board member. By being screwed together, the second game board member is fastened and fixed to the first game board member. According to such a gaming machine, the second game board member can be attached to and detached from the first game board member. That is, when a failure or breakage occurs in the second game board member, only the second game board member is replaced, and the replacement of the entire game board can be unnecessary. However, in the conventional gaming machine described above, every time the second game board member is replaced, the screwing of the female screw and the screw member is repeated, and the thread of the female screw is set (abrasion or galling). However, if the number of replacements increases, the reliability of fastening and fixing decreases.

  On the other hand, according to the gaming machine A1, the first gaming board member includes one or more screw members for fastening and fixing the second gaming board member, and the first gaming board member side can be screwed with the screw member. And a plurality of female screws are formed in the second game board member, and one or a plurality of insertion holes through which the screw members can be inserted are formed, and the second game board member is formed by a smaller number of screw members than the number of female screws. Is fastened and fixed to the first game board member, so that when the thread of one female thread is set (wear or galling), another female thread can be used. Therefore, even when the number of replacements increases, the reliability of fastening and fixing can be ensured.

  The cross-sectional shape of the insertion hole is arbitrary, and examples thereof include a circular shape, an elliptical shape, a polygonal shape, and a combination thereof. Further, the insertion hole only needs to be formed so that at least the screw member can be inserted, and a part of the peripheral surface may be opened. The open portion may be continuous along the insertion direction of the screw member, or may be only a part of the insertion direction.

Therefore, even when the number of replacements increases, the reliability of fastening and fixing can be ensured.

  In particular, according to the gaming machine A2, since the number of insertion holes is smaller than the number of female screws, when the second game board member is disposed in front of the first game board member so as to be visible, the screw member Can be reduced when the player is not inserted. Therefore, the area of another member for covering the insertion hole can be suppressed. It is preferable that the second game board member is fastened and fixed to the first game board member by the same number of screw members as the number of insertion holes. In this case, it is possible to eliminate the insertion hole visually recognized by the player in a state where the screw member is not inserted. Therefore, it is not necessary to cover the insertion hole with another member.

  Further, since the number of insertion holes can be reduced, the strength of the second game board member can be ensured accordingly. Here, since the second game board member is relatively small, it is difficult to secure its strength. On the other hand, when the second game board member is formed as a nail is implanted, the second game board member is formed when the nail is implanted or when a game ball collides with the nail during a game. On the other hand, it is necessary to secure strength. Therefore, in the second game board member in which nails are planted, it is particularly effective to reduce the number of insertion holes from the viewpoint of securing strength.

It can be prevented from being exposed on the front surface (game surface) of the board member. Therefore, the insertion hole in which the screw member is not inserted can be made difficult for the player to visually recognize, and the area of another member for covering the insertion hole can be suppressed or unnecessary. Also, since the head of the screw member is not exposed to the rolling surface (game surface) of the game ball, it is not necessary to provide a countersunk screw or to provide a counterbore (recess) for accommodating the head, thereby simplifying the structure. .

  The gaming machine A9, further comprising a member to be fastened which is displaceably supported on a back surface of the first gaming board member and in which the plurality of female threads are formed.

  According to the gaming machine A9, in addition to the effect achieved by the gaming machine A1, the fastening member provided with the plurality of female screws formed on the back surface of the first game board member so as to be displaceable is provided. In the case where the set thread is set (abrasion or galling), another female screw can be used by displacing the member to be fastened. Therefore, even when the number of replacements increases, the reliability of fastening and fixing can be ensured.

  In particular, according to the gaming machine A9, the member to be fastened is supported on the back surface of the first game board member, so that when the second game board member is removed, the member to be fastened does not fall off, or (2) When attaching the game board member, the operator does not need to manually hold the member to be fastened from the back of the first game board member in order to screw the screw member into the female screw of the member to be fastened. Therefore, when exchanging the second game board member, it is not necessary to open the first game board member (game board), and the second game board member (game board) is kept closed while the second game board member is closed. A game board member can be exchanged. Therefore, the workability of replacing the second game board member can be improved.

<About the concept of the invention with the winning opening unit 7300 as an example>
In a gaming machine comprising a first gaming board member and a second gaming board member fastened and fixed to the first gaming board member and forming a gaming board together with the first gaming board member, the first gaming board member includes A screw member for fastening and fixing the second game board member is provided, and an insertion hole through which the screw member is inserted is formed in the first game board member side, and is inserted through the insertion hole on the first game board member side. A gaming machine B1 wherein a female screw to which the formed screw member is screwed is formed on the second game board member.

  Here, there is known a gaming machine including a first gaming board member and a second gaming board member fastened and fixed to the first gaming board member and forming a gaming board together with the first gaming board member (for example, JP-A-2003-310905). An insertion hole is formed in the second game board member, and an internal thread is formed in the first game board member. A screw member inserted into the insertion hole of the second game board member is inserted into a female screw of the first game board member. By being screwed together, the second game board member is fastened and fixed to the first game board member. According to such a gaming machine, the second game board member can be attached to and detached from the first game board member. That is, when a failure or breakage occurs in the second game board member, only the second game board member is replaced, and the replacement of the entire game board can be unnecessary. However, in the conventional gaming machine described above, every time the second game board member is replaced, the screwing of the female screw and the screw member is repeated, and the thread of the female screw is set (abrasion or galling). However, if the number of replacements increases, the reliability of fastening and fixing decreases.

  On the other hand, according to the gaming machine B1, the insertion hole through which the screw member is inserted is formed on the first game board member side, and the screw member inserted through the insertion hole on the first game board member side is screwed. Since the combined female screw is formed in the second game board member, a new female screw can be used when the second game board member is replaced. Therefore, even when the number of replacements increases, the reliability of fastening and fixing can be ensured.

  The cross-sectional shape of the insertion hole is arbitrary, and examples thereof include a circular shape, an elliptical shape, a polygonal shape, and a combination thereof. Further, the insertion hole only needs to be formed so that at least the screw member can be inserted, and a part of the peripheral surface may be opened. The open portion may be continuous along the insertion direction of the screw member, or may be only a part of the insertion direction.

  The gaming machine B1 includes a protrusion protruding from the first surface of the second game board member, and a concave portion recessed on the second surface of the first game board member so as to receive the protrusion. The gaming machine B2, wherein the female screw is formed at a projecting portion of the second game board member, and the insertion hole is formed to communicate with a recess of the first game board member.

  According to the gaming machine B2, in addition to the effect provided by the gaming machine B1, a protrusion protruding from the first surface of the second game board member, and the second surface of the first game board member capable of receiving the protrusion. The female screw is formed in the protrusion of the second game board member, and the insertion hole is formed in communication with the concave portion of the first game board member. The length of the part (completely threaded part) can be secured. Therefore, the axial force of the screw member can be increased accordingly, and the second game board member can be easily fastened and fixed firmly to the first game board member.

  Since the second game board member is relatively small, it is difficult to secure its strength. However, as in the gaming machine B2, a female screw is formed on the protruding portion to secure the length of the screw portion. By doing so, it is possible to distribute the load on the second game board member while allowing a predetermined axial force to be applied to the screw member. In other words, the configuration in which the internal thread is provided on the projection is particularly effective from the viewpoint of achieving both strong fastening and fixing and prevention of damage to the second game board member.

  In the gaming machine B2, the projecting dimension of the projection is set to be larger than the dimension of the recessed section.

  According to the gaming machine B3, in addition to the effect of the gaming machine B2, the projecting dimension of the protrusion is set to be larger than the recess dimension of the concave portion, so that the second gaming board member is replaced with the first gaming board member. On the other hand, in the state of being fixed and fixed, a state can be formed in which the protruding tip of the protruding portion and the concave bottom surface of the concave portion are in contact. That is, a state in which a gap is formed between the first surface of the second game board member and the second surface of the first game board member can be formed. Therefore, the second game board member can be easily displaced relative to the first game board member by utilizing the elastic deformation of the projection. As a result, for example, when a nail is implanted in the second game board member, the vibration when the game ball collides with the nail during the game can be absorbed, and breakage (breakage) of the nail can be suppressed.

  In this case, it is preferable that the inner diameter of the recess is set to be smaller than the outer diameter of the protrusion. In addition, it is preferable that the second game board member and the first game board member do not abut on other portions except for the protruding tip of the protrusion and the concave bottom surface of the recess. This is because the protrusions can be more easily elastically deformed.
