Description

The present invention relates to a gaming machine in which a gaming area in which a gaming ball can flow down is formed on the front surface of the gaming board.

In the gaming machine of Patent Document 1, the reversion of the gaming ball to the guide path for guiding the gaming ball launched from the launching device to the gaming area is regulated by the ball return regulating member.

Patent No. 4485513 (Fig. 1)

However, the gaming machine of Patent Document 1 has a problem that the ball return regulating member is easily damaged.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a gaming machine capable of suppressing damage to a ball return regulating member.

The first invention is a game board having a game area on the front surface through which a game ball can flow down, and an inside of an opening through which a game ball protruding from the front surface of the game board and flowing down the game board penetrates the game board. An entry control frame that regulates entry into the game, an outer rail portion that surrounds the game area and has an arc-shaped upper portion, and an inner rail that is curved in an arc shape and faces the left side portion of the outer rail from the inside. A guide path formed between the outer rail portion, the outer rail portion, and the inner rail portion to guide the game ball launched from the launching device to the game area, and regulate the backflow of the game ball to the guide path. In a game machine provided with a ball return restricting member, the approach restricting frame includes an upper arc wall extending in an arc shape along the upper portion of the outer rail portion on an extension line of the inner rail portion, and the upper arc wall. The ball return restricting member is a support base fixed to the inner rail portion, including a flow-down guide wall that extends downward from the left end portion of the ball and is capable of guiding the flowing game ball downward. An opening / closing member that is rotatably supported by the support base, moves along the front surface of the game board to open / close the guide path, and is normally urged to a closed position that closes the guide path. In the game area, a resin base plate laid on the front surface of the game board and an opposed resin protrusion portion protruding from the base plate and arranged to face the ball return restricting member are provided and opened. The distance between the ball return restricting member in the state and the facing resin protrusion is larger than one game ball, and the distance between the flow guide wall and the facing resin protrusion is larger than one game ball. A nail member is provided adjacent to a distance of less than one game ball on the right side of the support base of the ball return restricting member, which is 5 or less, below the lower end of the facing resin protrusion. The upper edge portion of the base plate is arranged on an imaginary arc line connecting the inner rail portion and the upper arc wall, and the right end portion of the upper edge portion of the base plate is adjacent to the upper arc wall. The left end portion of the upper edge portion of the base plate is bent so as to avoid the ball return restricting member .

In the first invention, since the opposing resin protrusions are provided so as to face the ball return restricting member, the game ball is less likely to collide with the ball return restricting member, and damage to the ball return regulating member is suppressed. Further, since the distance between the ball return restricting member in the open state and the facing resin protrusion is larger than that of one game ball, when the game ball collides with the ball return restricting member, the game ball faces the ball return regulating member. It is possible to flow down between the resin protrusion and the resin protrusion.

In the present invention, since the opposing resin protrusions are provided so as to face the ball return restricting member, the game ball is less likely to collide with the ball return restricting member, and damage to the ball return regulating member is suppressed.

A launch mechanism unit 60 is provided in the lower right corner of the front surface of the game machine main body 10H, and a game ball launched from the launch device 61 of the launch mechanism unit 60 is placed on the front surface of the game board 11 in the game area YR1. A guide path 13 for guiding to the upper left is formed. Further, as shown in FIG. 4, a return ball recovery duct 68 is provided on the left side of the launch mechanism unit 60. The return ball recovery duct 68 is arranged between the launch rail 61R provided in the launch mechanism unit 60 and the guide path 13, and does not reach the game area YR1 due to the weak launch force, and the return ball recovery duct 68 returns to the guide path 13. Then, the game balls that have not reached the guide path 13 are collected and discharged to the lower plate 28.

As shown in FIG. 5, the launch mechanism unit 60 is mainly composed of a launch device 61 and a ball supply device 62. Specifically, the launch mechanism unit 60 is formed by assembling parts such as a ball supply device 62, a launch rail 61R, a striking mallet 63, and a launch motor 64 to a base plate 61A of the launch device 61. The ball supply device 62 supplies the game balls housed in the upper plate 27 one by one on the launch rail 61R. The launch rail 61R extends diagonally downward to the right from a position near the upper left end of the base plate 61A, and the game ball supplied on the launch rail 61R is received by the ball receiving member 65. The launch motor 64 is driven by the rotation operation of the launch handle 28. The striking mallet 63 rotates by receiving the driving force of the launching motor 64. When the batting mallet 63 is rotated and placed at the batting position, the mallet tip 63S of the batting mallet 63 repels the game ball received by the ball receiving member 65. As a result, the game ball is launched diagonally upward along the launch rail 61R.

As shown in FIG. 2, a guide rail 12 surrounding the game area YR1 projects from the front surface of the game board 11. The guide rail 12 is formed by a first rail 12A and a second rail 12B curved in an arc shape, and a cushioning member 12C. The first rail 12A is arranged along the upper peripheral portion of the game area YR1 excluding the approximately 1/4 circumference. A part of the second rail 12B (the upper part of the second race 12B) extends along a substantially 1/4 circumference of the upper side in the peripheral portion of the game area YR1, and the remaining part (the upper part of the second rail 12B). The left side) is arranged so as to face the left side of the first rail 12A from the outside. One end of the second rail 12B is arranged on the left side with respect to the lowermost portion of the first rail 12A, and the other end of the second rail 12B is the game ball 1 with respect to the right end 12AR of the first rail 12A. It is placed at a position offset upward by ~ 2 pieces. The guide path 13 described above is formed between the left side portion of the first rail 12A and the second rail 12B. The cushioning member 12C is attached to the right end portion 12AR of the first rail 12A and closes between the first rail 12A and the second rail 12B.

Further, a gap for one or two game balls is provided between the left end portion 12AL of the first rail 12A and the intermediate portion of the second rail 12B, thereby guiding the guide rail 12 to the upper left portion. An entrance 12K for allowing the game ball to enter the exit of the road 13, that is, the game area YR1 is formed. Then, the portion of the second rail 12B arranged above the entrance 12K forms an arc-shaped guide portion 12E capable of guiding the game ball that has entered the game area YR1 from the entrance 12K diagonally upward to the right. There is.

As shown in FIGS. 6, 7 and 8, in the gaming machine 10 of the present embodiment, a ball that restricts the gaming ball that has entered the gaming area YR1 from returning to the guide path 13 on the first rail 12A. The return restricting member 50 is attached. Hereinafter, the ball return restricting member 50 will be described in detail.

As shown in FIGS. 8A and 8B, the ball return restricting member 50 is rotatably supported by the support base 51 attached to the left end portion 12AL of the first rail 12A and the support base 51. It is mainly composed of an opening / closing member 53 that opens and closes the entrance 12K. Then, the ball return restricting member 50 is in the closed state when the opening / closing member 53 is arranged in the closed position where the entrance 12K is closed, and is in the open state when the opening / closing member 53 is arranged in the open position where the entrance 12K is opened.

The opening / closing member 53 is a return ball contact surface (not shown) with which the launch ball contact surface 54A to which the game ball passing through the guide path 13 contacts and the game ball from the game area YR1 to the guide path 13 side. The rotating shaft portion 55 is composed of a movable piece 54 having the above and two sides, a rotating shaft portion 55, and a weight portion 56 arranged on the opposite side of the movable piece 54 with the rotating shaft portion 55 interposed therebetween. Rotates around. Then, the opening / closing member 53 enters by rotating so as to widen the distance between the movable piece 54 and the second rail 12B from the closed position (see FIG. 13A) in which the movable piece 54 closes the entrance 12K. It is arranged at an open position (see FIG. 13B) that opens the mouth 12K. The weight portion 56 is for urging the opening / closing member 53 to the closed position. Specifically, the weight portion 56 is formed with a mounting hole 56A into which the core material 57 is mounted in parallel with the rotation shaft portion 55, and the core material 57 is mounted in the mounting hole 56A. The center of gravity of the opening / closing member 53 is biased toward the weight portion 56. When the opening / closing member 53 is arranged in the closed position, the movable piece 54 is arranged substantially vertically, and when the opening / closing member 53 is arranged in the open position, the movable piece 54 faces diagonally upward to the right from the rotating shaft portion 55. Arranged to extend.

As shown in FIG. 8B, the support base 51 is provided with a storage recess 51A capable of accommodating the rotation shaft portion 55 and the weight portion 56 of the opening / closing member 53. On both sides of the accommodating recess 51A, there are a rear wall 52A arranged to face the game board 11 when the support base is attached to the first rail 12A, and a front wall 52B arranged to face the game board 11. Is formed, and a pin insertion hole 58A is formed in the rear wall 52A so that a rotation pin 58 penetrating the rotation shaft portion 55 of the opening / closing member 53 can be inserted from the outside.

As shown in FIG. 2, a display opening 11H is formed through the center of the game area YR1 in the game board 11, and the display device 30 faces the display opening 11H from the back surface side of the game board 11. There is. The display device 30 is composed of, for example, a liquid crystal module, and has a display screen 30G on the front surface for producing an effect related to the game.

A display decorative frame 23 is attached to the center of the front surface of the game board 11 so as to surround the display screen 30G. The display decorative frame 23 is fitted into the display opening 11H from the front side of the game board 11 and projects forward from the front side of the game board 11. As a result, the game ball flowing down the game area YR1 is prevented from passing over the display decoration frame 23 and entering the inside of the display decoration frame 23.

Specifically, the display opening 11H is arranged closer to the upper side in the middle portion in the lateral direction of the game area YR1, and game balls are arranged on the left side, the right side side, and the lower side of the display decoration frame 23 in the game area YR1, respectively. A flowable left flow area YR2, a right flow area YR3, and a lower flow area YR4 are formed. Further, an upper arc wall 25 extending in an arc shape along the upper portion (specifically, the second rail 12B) of the guide rail 12 is provided at the upper end portion of the display decorative frame 23, and the upper arc wall 25 is provided. An upper connecting flow path 25R through which game balls can pass is formed between the 25 and the guide rail 12. Further, the display decorative frame 23 fills the space between the display opening 11H and the right side portion of the guide rail 12 (specifically, the right end portion 12AR of the first rail 12A) without a gap, and also fills the upper connecting flow path 25R and the right side flow down. The right side connecting flow path 24R that communicates with the region YR3 is provided with a right side connecting flow path component 24 formed inside.

A wind turbine 19 is provided at the lower end of the left flow area YR2. The wind turbine 19 changes the course of the game ball that has flowed down the left flow-down area YR2 to the center side, and guides the game ball to the lower flow-down area YR4.

A first starting winning opening 14A is provided at the center of the lower flow area YR4 in the lateral direction. Further, a plurality of general winning openings 20 are provided along the guide rail 12 (specifically, the first rail 12A) in the portion of the lower flow area YR4 on the left side of the first starting winning opening 14A.

A large winning opening 15 is provided in a portion of the lower flow area YR4 on the right side of the first starting winning opening 14A. Further, in the right flow area YR3, a start gate 18 and a second start winning opening 14B are provided side by side in the vertical direction. Specifically, the starting gate 18 and the second starting winning opening 14B are located above the large winning opening 15. A side winning opening 21 is provided in a portion of the lower flowing area YR4 located diagonally above the right of the large winning opening 15.

A game ball enters any of the general winning opening 20, the side winning opening 21, the first starting winning opening 14A, the second starting winning opening 14B, and the large winning opening 15, and the winning ball is not shown. When detected by the ball detection sensor, a predetermined number of prize balls are paid out to the upper plate 26. Further, at the lower end of the game area YR1, an out port 16 for discharging the game ball to the outside of the game area YR1 is provided, and the game ball that has not entered any of the winning ports is out. It is collected from the mouth 16 by a ball collecting device (not shown). Further, in the game area YR1, a large number of obstacle nails 17 for randomly changing the flow direction of the game ball are planted.

Next, the details of the winning openings 14A, 14B, 15, 20, 21 and the starting gate 18 will be described. The general winning opening 20 and the side winning opening 21 have a so-called pocket structure and are opened upward in a size capable of inserting one game ball at a time.

The starting gate 18 has a gate-shaped structure through which a game ball can dive. When the game ball passes through the starting gate 18, a normal symbol hit / miss determination is performed. Here, in the gaming machine 10, the probability that the normal symbol winning / failing determination will be a hit in the normal gaming state is set low, and after the "big hit game" described later, when a predetermined condition is satisfied, the normal symbol winning / failing determination is made. A "short-time game" is executed in which the probability of winning is high. Therefore, in the normal gaming state, the gaming machine 10 launches a game ball so as to flow down the left flow-down area YR2, so-called “left-handed”, and flows down the right-side flow-down area YR3 during the “time saving game”. It is configured to be able to provide the player with two types of hitting methods, such as hitting a game ball as if to hit, so-called "right hitting". In the "time saving game", after the end of the "big hit game", the number of winnings to the first and second starting winning openings 14A and 14B reaches the specified upper limit number (for example, 100 times), or the number of winnings thereof It ends when a big hit occurs during the "short-time game".

Like the general winning opening 20 and the side winning opening 21, the first starting winning opening 14A has a pocket structure and is open upward with a size that allows one game ball to enter. The second starting winning opening 14B is opened to the right side with a size that allows game balls to enter one by one, and is opened and closed by the movable member 14C. Normally, the movable member 14C is arranged substantially vertically to close the second start winning opening 14B, and when the above-mentioned normal symbol winning / failing determination is successful, the movable member 14C rotates in the left-right direction around the lower end portion. When the movable member 14C rotates and inclines downward to the left, a game ball can enter (win) the second starting winning opening 14B. When a game ball enters (wins) the first and second starting winning openings 14A and 14B, a special symbol winning / failing determination is performed. Then, when the special symbol winning / failing determination is successful, the normal gaming state shifts to the jackpot gaming state, and the jackpot game is executed.

The large winning opening 15 has a horizontally long rectangular shape, and is closed by the movable door 15T in the normal gaming state. Then, when the game state becomes the big hit game state and the big hit game is executed, the movable door 15T is tilted forward for a predetermined period. Then, the large winning opening 15 opens forward, and a large number of game balls can be won in the large winning opening 15 by guiding the movable door 15T.

As shown in FIG. 9, in the upper left portion of the display decorative frame 23, a flow-down guide wall 32 that receives the game ball flowing down from the arc-shaped guide portion 12E side of the guide rail 12 and can guide it downward is provided. There is. The flow guide wall 32 includes a vertical wall 33 extending downward from the left end of the upper arc wall 25, a horizontal wall 34 extending downward from the lower end of the vertical wall 33, and a guiding inclined wall 35 extending downward from the left end of the horizontal wall 34. It is composed of and has a crank shape as a whole. Specifically, the vertical wall 33, the horizontal wall 34, and the guide inclined wall 35 all incline downward to the left, the downward slope of the vertical wall 33 is larger than the downward slope of the horizontal wall 34, and the downward slope of the guided inclined wall 35 is the horizontal wall 34. It is larger than the downward slope of. The downward slope of the guided inclined wall 35 is smaller than the downward slope of the vertical wall 33.

A ball introduction area YR5 is formed in a portion of the game area YR1 sandwiched between the flow-down guide wall 32 and the arc-shaped guide portion 12E, and the ball introduction area YR5 is provided separately from the display decorative frame 23. The resin body 40 is fixed. The resin body 40 includes a base plate 40A laid on the front surface of the game board 11 and a resin protrusion 40T protruding forward from the base plate 40A. Then, in the portion of the ball introduction region YR5 excluding the resin protrusion 40T, a nailless region YR6 is formed in which the game ball can flow down without having the obstacle nail 17. The resin body 40 is fixed to the game board 11 by screwing the base plate 40A with the bolts 40B. Further, the resin body 40 is made of a transparent resin so that the rear side of the base plate 40A can be seen through.

The display decorative frame 23 is provided with an overhanging piece 36 that projects outward from the flow-down guide wall 32 and is overlapped with the front surface of the game board 11, and the portion of the base plate 40A facing the flow-down guide wall 32 side is provided. A boundary edge portion 40F (see FIGS. 10 to 12) having a shape corresponding to the overhanging piece 36 is provided. The boundary edge portion 40F is arranged along the overhanging piece 36. As a result, it is possible to prevent the game ball from entering between the overhanging piece 36 and the base plate 40A. Specifically, both the overhanging piece 36 and the boundary edge portion 40F are formed in a crank shape corresponding to the flow-down guide wall 32.

As shown in FIG. 14, the portion of the overhanging piece 36 facing the boundary edge portion 40F is formed in a tapered shape that becomes thinner as it approaches the boundary edge portion 40F, and is inclined to the rear side as it approaches the boundary edge portion 40A. It has an inclined surface 36K on the front surface. Therefore, after the display decorative frame 23 is attached to the display opening 11H of the game board 11, the base plate 40A can be arranged next to the overhang piece 36 by using the tapered portion of the overhang piece 36 as a guide. .. Further, the portion of the boundary edge portion 40F of the base plate 40A facing the overhanging piece 36 is formed in a cliff shape, and has a cliff 40S orthogonal to the front surface of the game board 11 as an end face. Therefore, it is possible to reduce the dent formed between the overhanging piece 36 and the base plate 40A, and the game ball can flow smoothly.

Further, as shown in FIG. 9, the upper edge portion of the base plate 40A is arranged in an arc shape along the extension line of the first rail 12A. Then, between the base plate 40A and the second rail 12B, a ball passage path through which the game ball can pass is formed along the second rail 12B. As a result, it is suppressed that the game ball that has entered the game area YR1 from the entrance 12K comes into contact with the base plate 40A and the momentum of the game ball is reduced.

As shown in FIG. 14, the upper edge portion of the base plate 40A becomes thinner as it approaches the second rail 12B, and has an inclined surface 40K that inclines rearward as it approaches the second rail 12B on the front surface. There is. As a result, in the present embodiment, the game ball moving along the arc-shaped guide portion 12E is smoothly flowed down to the nailless region YR6 in front of the base plate 40A by guiding the upper edge portion of the base plate 40A. Can be done.

As shown in FIG. 2, the gaming machine 10 includes a first resin protrusion 41, a second resin protrusion 42, and a third resin protrusion 43 as the resin protrusion 40T. The first resin protrusion 41, the second resin protrusion 42, and the third resin protrusion 43 are arranged along the arc-shaped guide portion 12E in order from the side closer to the vertical wall 33, that is, from the right side.

As shown in FIG. 10, the first resin protrusion 41 faces the upper end of the vertical wall 33 from the left side, that is, from the entrance 12K side, and one game ball passes between the first resin protrusion 41 and the vertical wall 33. A possible first flow path R1 is formed. The first resin protrusion 41 has a substantially rectangular shape in front view, and has a ceiling surface 41U extending along an arc-shaped guide portion 12E and a substantially horizontal bottom surface 41S.

The right side surface of the first resin protrusion 41 is composed of an upper right-facing flow path forming surface 41RA and a lower right-facing flow path forming surface 41RB. The upper right-facing flow path forming surface 41RA extends substantially vertically, and the lateral width of the first flow path R1 narrows as it goes downward. This makes it possible to reduce the momentum of the game ball flowing down the first flow path R1. Further, the lower right-facing flow path forming surface 41RB is inclined so as to be separated from the vertical wall 33 from the lower end of the upper right-facing flow path forming surface 41RA toward the lower side, and the width of the first flow path R1 is widened toward the lower side. .. As a result, the game ball that has flowed down the first flow path R1 can be swiftly flowed downward.

The left side surface of the first resin protrusion 41 is composed of a left-facing flow path forming surface 41L extending substantially vertically.

As shown in FIG. 10, the second resin protrusion 42 is arranged diagonally downward to the left with respect to the first resin protrusion 41, and a game ball can pass between the second resin protrusion 42 and the first resin protrusion 41. 1 The inter-protrusion flow path TR1 is formed. Here, the right side surface of the second resin protrusion 42 is composed of a right-facing flow path forming surface 42R that is inclined downward to the right. Further, as described above, the left-facing flow path forming surface 41L of the first resin protrusion 41 is substantially vertical. As a result, the flow path TR1 between the first protrusions is formed to be narrower as it goes downward. As a result, it is possible to reduce the momentum of the game ball flowing down the first inter-projection flow path TR1, and the game ball flowing down from the first inter-projection flow path TR1 is along the second flow path R2 described later. It becomes easy to flow down.

Further, the second resin protrusion 42 is arranged above the side wall 34, and forms a second flow path R2 through which the game ball can pass between the second resin protrusion 42 and the side wall 34. The second resin protrusion 42 has a substantially triangular shape pointed upward and has a bottom surface 42S substantially parallel to the side wall 34. As a result, the game ball passing through the second flow path R2 can be easily moved along the lateral wall 34, and the game ball can easily collide with the third resin protrusion 43 and flow down to the third flow path R3 described later. .. The distance between the bottom surface 42S of the second resin protrusion 42 and the side wall 34, that is, the flow path width (vertical distance) of the second flow path R2 is 2 or more and less than 3 game balls. ing.

The left side surface of the second resin protrusion 42 is composed of a left-facing flow path forming surface 42L extending substantially vertically.

As shown in FIG. 11, the third resin protrusion 43 is arranged diagonally downward to the left with respect to the second resin protrusion 42, and a game ball can pass between the third resin protrusion 43 and the second resin protrusion 42. The flow path TR2 between the two protrusions is formed. Specifically, the right side surface of the third resin protrusion 43 is provided with an upper right-facing flow path forming surface 43RA that inclines downward to the right, and the upper right-facing flow path forming surface 43RA and the second resin of the third resin protrusion 43. A second inter-protrusion flow path TR2 is formed between the protrusion 42 and the left-facing flow path forming surface 42L.

Here, as described above, since the left-facing flow path forming surface 42L of the second resin protrusion 42 is substantially vertical, the second protrusion-to-protrusion flow path TR2 is configured to become narrower as it goes downward. .. As a result, it is possible to reduce the momentum of the game ball flowing down the second inter-projection flow path TR2, and the game ball flowing down from the second inter-projection flow path TR2 is moved along the second inter-projection flow path R2. It becomes easy to let it flow down or to flow down along the third flow path R3 described later.

Further, the third resin protrusion 43 is arranged on an extension line of the lateral wall 34, and forms a third flow path R3 with the induction inclined wall 35. Specifically, the right side surface of the third resin protrusion 43 is provided with a lower right-facing flow path forming surface 43RB extending from the lower end of the upper right-facing flow path forming surface 43RA along the induction inclined wall 35, and the third resin protrusion 43. A third flow path R3 is formed between the lower right-facing flow path forming surface 43RB of the portion 43 and the induction inclined wall 35. The lower right-facing flow path forming surface 43RB is substantially parallel to the induction inclined wall 35.

As described above, the third resin protrusion 43 is arranged on the extension line of the side wall 34, and is configured to collide with the game ball flowing down along the side wall 34 so that the flow direction of the game ball can be changed. As a result, the momentum of the game ball flowing down along the side wall 34 is suppressed, and the game ball is prevented from moving to the outer edge of the game area YR1 and colliding with the guide rail 12, or the game nail. By suppressing the direct contact with the (obstacle nail 17), the nail breakage of the game nail is suppressed, and the game ball can flow smoothly. Moreover, since the lower right-facing flow path forming surface 43RB arranged on the extension line of the third resin protrusion 43 extends along the induction inclined wall 35, the game ball flowing down along the side wall 34 can be seen. It is possible to collide with the lower right-facing flow path forming surface 43B and flow down along the induction inclined wall 35.

Here, the distance between the third resin protrusion 43 (lower right-facing flow path forming surface 43RB) and the induction inclined wall 35, that is, the width of the third flow path R3 is larger than one game ball and 1 It is less than .5 pieces. As a result, the fluttering of the game ball passing through the third flow path R3 is suppressed, and the game ball can flow smoothly.

Further, as shown in FIG. 12, the third resin protrusion 43 is arranged on the right side of the left end portion 12AL of the first rail 12A and faces the ball return restricting member 50 from the right side. The distance between the third resin protrusion 43 and the ball return restricting member 50 is larger than one game ball, and the third resin protrusion 43 is in the fourth flow between the third resin protrusion 43 and the ball return restricting member 50. The road R4 is formed. Specifically, the left side surface of the third resin protrusion 43 has an upper left-facing flow path forming surface 43LA that inclines downward to the left and a support base 51 of the ball return regulating member 50 that extends downward from the upper left-facing flow path forming surface 43LA. It is composed of a lower left-facing flow path forming surface 43LB that surrounds the circumference in an arc shape. Then, an upstream portion of the fourth flow path R4 is formed between the upper left-facing flow path forming surface 43LA and the opening / closing member 53 of the ball return restricting member 50, and the lower left-facing flow path forming surface 43LB and the ball return regulating member 50. A downstream portion of the fourth flow path R4 is formed between the support base 51 and the support base 51 of the fourth flow path R4.

Here, the lower left-facing flow path forming surface 43LB is formed in an arc shape surrounding the support base 51 of the ball return restricting member 50 from the outside, and the downstream portion of the fourth flow path R4 is outside the support base 51. It extends in an arc shape so as to trace the left side. As a result, the game ball is prevented from colliding with the support base 51 that rotatably supports the opening / closing member 53, and the opening / closing member 53 can be smoothly rotated. Further, the distance between the lower left-facing flow path forming surface 43LB and the support base 51 (that is, the flow path width of the downstream portion of the fourth flow path R4) is larger than one game ball and 1.5 or less. It has become. As a result, the game ball passing between the support base 51 and the third resin protrusion 43 can be smoothly flowed down.

Further, as described above, the opening / closing member 53 is placed between the closed position where the entrance 12K is closed (see FIG. 13A) and the opening position where the entrance 12K is opened (see FIG. 13B). Rotates along the front of the. Therefore, the flow path width of the upstream portion of the fourth flow path R4 changes depending on the arrangement of the opening / closing member 53. Specifically, the flow path width of the upstream portion of the fourth flow path R4 is narrower when the opening / closing member 53 is arranged at the open position than when the opening / closing member 53 is arranged at the closed position. ..

The distance between the movable piece 54 and the upper left-facing flow path forming surface 43LA when the opening / closing member 53 is arranged in the open position (that is, when the ball return restricting member 50 is in the state where the entrance / exit 12K is opened to the maximum). Is larger than one game ball and 1.5 or less. This makes it possible to suppress the fluttering of the game ball passing through the upstream portion of the fourth flow path R4. Further, since the upper left-facing flow path forming surface 43LA is arranged substantially parallel to the movable piece 54 when the opening / closing member 53 is arranged in the open position, the opening / closing member 53 is arranged in the open position and the fourth flow path R4. Even if the width of the flow path is narrowed, it is possible to prevent the game balls from repelling each other between the opening / closing member 53 and the third resin protrusion 43, so that the game balls can smoothly flow down to the fourth flow path R4. It becomes.

Further, as shown in FIG. 13A, when the opening / closing member 53 is arranged at the closed position, the movable piece 54 and the upper left-facing flow path forming surface 43LA become formed on the upstream side portion of the fourth flow path R4 (that is, the movable piece 54 and the upper left direction flow path forming surface 43LA). The width of the flow path of the sandwiched portion) becomes narrower toward the downstream side. As a result, it is possible to reduce the momentum of the game ball flowing down the fourth flow path R4 and allow the game ball to flow down smoothly.

As shown in FIGS. 9 and 12, a plurality of obstacle nails 17 are provided in a portion of the game area YR1 located below the third resin protrusion 43. The plurality of obstacle nails 17 are arranged on the extension line of the lower right-facing flow path forming surface 43RB of the third resin protrusion 43, and have a space between the third resin protrusion 43 and the guide inclined wall 35 so that the game ball can pass through. A passable nail 17A is included. As a result, when the game ball flows down the third flow path R3 between the induction inclined wall 35 and the lower right-facing flow path forming surface 43RB, it is possible to prevent the obstacle nail 17 from hindering the flow of the game ball. .. The ball passage allowable nail 17A may be arranged away from the guide inclined wall 35 with respect to the extension line of the lower right-facing flow path forming surface 43RB.

A gap larger than one game ball and smaller than two game balls is formed between the third resin protrusion 43 and the ball passage allowable nail 17A. Then, the game ball that has flowed down the fourth flow path R4 between the ball return restricting member 50 and the third resin protrusion 43 can be moved toward the induction inclined wall 35.

As shown in FIGS. 9 to 13, in the game machine 10 of the present embodiment, the ball return suppressing unit 45 that suppresses the game ball once entering the game area YR1 from returning to the guide path 13 in the resin protrusion 40T. Is provided. The ball return suppressing portion 45 is provided in the second resin protrusion 42 and the third resin protrusion 43, but is provided in any one of the second resin protrusion 42 and the third resin protrusion 43. Just do it. In any case, the ball return suppressing portion 45 is provided in the resin protrusion 40T arranged on the side closer to the guide path 13 among the plurality of resin protrusions 40T.

As shown in FIG. 10, the ball return suppressing portion 45 provided in the second resin protrusion 42 is composed of an upper end protrusion 42T protruding from the upper end portion of the right-facing flow path forming surface 42R. The upper end protrusion 42T projects toward a region of the ball introduction region YR5 through which a game ball moving along the arc-shaped guide portion 12E can pass.

As shown in FIG. 11, the ball return suppressing portion 45 provided in the third resin protrusion 43 is composed of an upper end protrusion 43T protruding from the upper end portion of the upper right-facing flow path forming surface 43RA. Like the upper end protrusion 42T, the upper end protrusion 43T protrudes toward a region of the ball introduction region YR5 through which a game ball moving along the arc-shaped guide portion 12E can pass.

As described above, in the gaming machine 10, the ball return suppressing portion 45 is formed in a protruding shape toward the region of the ball introduction region YR5 through which the gaming ball moving along the arc-shaped guide portion 12E can pass. , The ball return suppressing unit 45 collides with the game ball heading toward the guide path 13, and it becomes possible to suppress the reversion of the game ball. Further, in the gaming machine 10, since the ball return suppressing portion 45 is provided in the second resin protrusion 42, it is possible to suppress the reversion of the game ball bounced back to the guide path 13 side by the first resin protrusion 41. it can. Moreover, as described above, the distance between the left-facing flow path forming surface 41L of the first resin protrusion 41 and the right-facing flow path forming surface 42R of the second resin protrusion 42, that is, the flow path TR1 between the first protrusions. Since the width of the flow path becomes narrower toward the lower side, it is possible to reduce the momentum of the game ball flowing down the flow path TR1 between the first protrusions and prevent the game ball from heading toward the guide path 13.

Further, in the gaming machine 10, since the ball return suppressing portion 45 is provided in the third resin protrusion 43, it is possible to suppress the reversion of the game ball bounced back to the guide path 13 side by the second resin protrusion 42. it can. Moreover, as described above, the distance between the left-facing flow path forming surface 42L of the second resin protrusion 42 and the upper right-facing flow path forming surface 43RA of the third resin protrusion 43, that is, the flow path between the second protrusions. Since the width of the flow path of the TR2 becomes narrower toward the lower side, it is possible to reduce the momentum of the game ball flowing down the flow path TR2 between the second protrusions and prevent the game ball from heading toward the guide path 13. ..

Further, in the gaming machine 10, the ball return suppressing portion 45 is inclined downward to the right, that is, an inclined surface (with the right-facing flow path forming surface 42R of the second resin protrusion 42) which is inclined downward as the distance from the guide path 13 is increased. Since it protrudes from the upper end of the upper right-facing flow path forming surface 43RA) of the third resin protrusion 43, the ball return suppressing portion 45 is applied to the game ball that is going toward the guide path 13 side without being received by the inclined surface. Collision with each other makes it possible to suppress the reversion of the game ball. Moreover, since the game ball received on the inclined surface can be moved to the side away from the guide path 13, the reversion of the game ball can be further suppressed.

Further, the ball return suppressing portion 45 projects from the upper end portion of the right-facing flow path forming surface 42R forming the first inter-projection flow path TR1 and the upper right-facing flow path forming surface 43RA forming the second inter-projection flow path TR2. Therefore, it is possible to suppress the reversion of the game ball while ensuring the flow path width in which the game ball can smoothly flow down in the flow paths TR1 and TR2 between the protrusions. In a configuration in which the ball return suppressing portion 45 is not provided on the flow path forming surfaces 42R and 43RA, a sufficient flow path width can be secured for the flow paths TR1 and TR2 between the protrusions, but the ball returns to the game ball. Is likely to occur.

By the way, in the game machine 10, for example, as shown in FIG. 17, a state in which two game balls are connected by a thread S and one of the game balls is left in the player's hand (that is, the upper plate 26 and the lower plate 27). The other game ball is driven into the game area YR1 in the state left in the above), which is a so-called thread hanging goto, which may be a fraudulent act. In the thread suspension goto, when one game ball is operated, the other game ball is guided to the winning openings 14A, 14B, 20, 21 in the game area YR1, and the right to judge whether the special symbol is correct or not or the prize ball is illegally given. Will be acquired.

In order to prevent such thread hanging goto, in the conventional gaming machine, for example, a fraud prevention member (not shown) is attached to the launch mechanism unit 60 (see, for example, Japanese Patent No. 5285728). This fraud prevention member is provided with a V-shaped cutting blade, and when a game ball is launched obliquely upward from the launching device 61 toward the game area YR1, the thread S attached to the game ball is used as the cutting blade. To capture or disconnect. However, the fraud prevention member is premised on the fact that the launching force of the gaming ball is strong enough to reach the gaming area YR1, and the thread S pulled diagonally upward by the gaming ball launched from the launching device 61 is cut. The cutting blade is placed in. Therefore, for example, the thread S attached to the game ball collected in the ball collection duct 68 due to its weak firing force could not be captured or cut. As a result, the firing force of one of the two game balls connected by the thread S is weakened, one of the game balls is intentionally discharged to the lower plate 28, and then the other game ball is discharged to the game area. There was a case where another thread hanging goto was performed to drive into YR1. In this other thread hanging goto, since one game ball is on the lower plate 28 when the other game ball is launched, the thread S is pulled downward, and the thread S is not caught or cut by the cutting blade.

In the gaming machine 10 of the present embodiment, in order to prevent the other thread hanging goto described above, an anti-fraud member that captures or cuts the thread S is attached to the first rail 12A (see FIGS. 6 and 7). Specifically, as shown in FIG. 15, a metal cover 70 made of, for example, a stainless steel metal plate is attached to the support base 51 of the ball return regulating member 50, and the metal cover 70 is attached to the metal cover 70. Two types of fraud prevention members, 1 fraud prevention member 81 and 2nd fraud prevention member 82, are provided. The metal cover 70 includes a main cover portion 71 that covers a portion of the support base 51 that faces the inside of the guide path 13, a rear cover portion 72A that covers the rear surface of the rear wall 52A of the support base 51, and a front wall 52B of the support base 51. It has a front cover portion 72B that covers the front surface, a first fraud prevention member 81 is formed on the main cover portion 71, and a second fraud prevention member 82 is formed on the front cover portion 72B.

First, the first fraud prevention member 81 will be described. As shown in FIGS. 15 and 16, the main cover portion 71 is formed in a vertically long rectangular shape, and has a notch 73 extending upward from the lower end at substantially the center in the front-rear direction of the main cover portion 71 and a notch 73. It has a front blade portion 74 and a rear blade portion 75 that are divided back and forth as boundaries. Then, the front blade portion 74 bends toward the inside of the guide path 13 so that the tips of the front blade portion 74 and the rear blade portion 75 are separated from each other, so that the front blade portion 74 and the rear blade portion 75 are separated from each other. A first fraud prevention member 81 having a V-shaped cutting portion 76 is formed. Further, each lower end edge of the front blade portion 74 and the rear blade portion 75 is provided with an inclination guide portion 77 that is inclined toward the cutting portion 76 toward the upper side.

As described above, in the first fraud prevention member 81, as shown in FIGS. 7, 15, and 16 (B), the front blade portion 74 is bent so as to plunge into the guide path 13 to cut the first fraud prevention member 81. The portion 76 is formed in a V shape when viewed from the front side. As a result, in the first fraud prevention member 81, the thread attached to the game ball is easily inserted into the V-shaped cutting portion 76. Further, in the first fraud prevention member 81, since the tilt guide portion 77 formed in each of the front blade portion 74 and the rear blade portion 75 is in contact with the cutting portion 76, the tilt guide portion 77 makes the game ball. The attached thread can be guided into the cutting portion 76.

Next, the second fraud prevention member 82 will be described. As shown in FIGS. 15 and 16 (A), the metal cover 70 penetrates the corner portion composed of the main cover portion 71 and the front cover portion 72B so as to straddle both the cover portions 71 and 72B. It has a hole 70A. As a result, notches 71K and 72BK are formed in the main cover portion 71 and the front wall portion 72. Further, the front cover portion 72B is formed with a pair of notches 83, 83 extending from the notch portion 72BK to the side opposite to the main cover portion 71 (that is, the side away from the guide path 13). Then, the inner blade portion 84 sandwiched between the pair of notches 83, 83 bends forward with respect to the outer blade portion 85 arranged on the outside of the pair of notches 83, 83, thereby forming the inner side. A second fraud prevention member 82 having a V-shaped cutting portion 86 is formed between the blade portion 84 and the outer blade portion 85.

As described above, in the second fraud prevention member 82, the inner blade portion 84 is bent forward, so that the cut portion 86 is formed in a V shape when viewed from the direction along the guide path 13. As a result, in the second fraud prevention member 82, when the thread S attached to the game ball rides on the front side of the first rail 12A, the thread S is easily inserted into the V-shaped cutting portion 86. It has become.

In the gaming machine 10 of the present embodiment, when the other thread hanging goto described above is performed, the thread S is pulled downward by one of the gaming balls on the lower plate 28, and the other gaming ball is moved into the gaming area YR1. Be driven in. Then, when the other game ball flows down in the game area YR1, the thread S is guided by the cutting portion 76 of the first fraud prevention member 81 or the cutting portion 86 of the second fraud prevention member 82 to be captured or cut. .. Note that FIG. 18 shows a state in which the thread S is captured by the first fraud prevention member 81, and FIG. 19 shows a state in which the thread S is captured by the second fraud prevention member 82. There is. This makes it possible to prevent another thread hanging goto.

The gaming machine 10 of the present embodiment may be configured to include only the second fraud prevention member 82. In this case, the main cover portion 71 may be provided with an guiding portion that guides the thread toward the cutting portion 86 of the second fraud prevention member 82 instead of the first fraud prevention member 81. The guide portion is provided with, for example, an inclined surface of the main cover portion 71 facing the guide path 13 side, which is inclined forward toward the downstream side of the guide path 13 (that is, the side approaching the entrance 12K). It is formed by.

According to the gaming machine 10 of the present embodiment described above, the following effects can be achieved.

In the gaming machine 10, the gaming ball launched from the launching device 61 is driven into the gaming area YR1 through the guide path 13. Here, when the game ball collides with a member (for example, the first resin protrusion 41 or the second resin protrusion 42) arranged in the game area YR1 and is bounced off, the game ball moves to the guide path 13. It is possible to go back. However, in the gaming machine 10 of the present embodiment, the gaming ball in the gaming area YR1 goes to the guide path 13 in the resin protrusion 40T (specifically, the second resin protrusion 42 and the third resin protrusion 43). Since the ball return suppressing unit 45 for suppressing the reversion is provided, the reversion of the game ball is suppressed.

Further, in the gaming machine 10, the resin protrusions 40T may be replaced for the purpose of maintenance of the resin protrusions 40T, change in the number and arrangement of the resin protrusions 40T, and the like. Here, in a configuration in which the resin protrusion 40T projects from the flange portion (overhanging piece 36) that projects outward from the display decoration frame 23 and is overlapped with the front surface of the game board 11, it is necessary to replace the entire display decoration frame 23. Therefore, it is considered that it takes time and effort to replace the resin protrusion 40T. However, in the gaming machine 10 of the present embodiment, since the resin body 40 having the resin protrusion 40T is provided separately from the display decorative frame 23, the resin protrusion 40T can be easily replaced. Become.

Further, in the game machine 10, the third resin protrusion 43 arranged on the extension line of the side wall 34 of the display decorative frame 23 collides with the game ball flowing down along the side wall 34 and changes the flow direction of the game ball. Since it is possible, the momentum of the flow of the game ball is suppressed, the game ball is prevented from moving to the outer edge of the game area YR1 and colliding with the guide rail 12, or the game nail (obstacle nail). By suppressing direct contact with 17), it is possible to suppress the breakage of the game nail and allow the game ball to smoothly flow downward.

Further, in the gaming machine 10, since the third resin protrusion 43 is arranged to face the ball return regulating member 50, the game ball is less likely to collide with the ball returning regulating member 50, and damage to the ball returning regulating member 50 is suppressed. .. Further, the distance between the ball return restricting member 50 in the open state (specifically, the movable piece 54 of the opening / closing member 53 arranged at the closed position) and the third resin protrusion 43 is larger than that of one game ball. Therefore, when the game ball collides with the ball return restricting member 50, the game ball can flow down between the ball return restricting member 50 and the third resin protrusion 43.
