Description

  The present invention relates to a gaming machine including a frame-shaped cover member that exposes a display area of a display device, and a plurality of game nails that change the direction of a game ball flowing down in the game area.

A pachinko machine wins a prize when a game ball enters a prize opening. In order to guide the game ball or change the path of the game ball in the game area, a plurality of game balls are placed in the game area. Has game nails. However, in recent pachinko machines, since the display area of the display device tends to be enlarged, the area where game nails are implanted is becoming smaller. As a result, the number of game nails decreases and the number of game ball paths decreases, so that the game balls pass through a specific path. When the display device is a rectangular device such as a liquid crystal display device, a frame-shaped cover member (center accessory) is attached to protect the display device. The game ball rolling passage gradually lowers from the center to the left side. For this reason, a part of the game ball flowing down in the game area may roll on the game ball rolling path and collide with a specific game nail located on the left side of the lower end of the game ball rolling path. Get higher. In particular, in recent years when the display device has become larger, the cover member is also enlarged and the game ball rolling path becomes longer, so the momentum of the game ball tends to increase. As a result, the load applied to the specific game nail at the time of the collision increases, so that the specific game nail may be damaged. Moreover, since a large number of game balls collide with the game nails every day, there is a high possibility that the game nails will be damaged. If the game nail is broken, the set value intended by the producer is not obtained, which leads to a disadvantage to the player or the game store. Thus, in recent years, various techniques have been proposed in view of these circumstances (see, for example, Patent Documents 1 to 4).
JP-A-6-210052 (Claim 1, [0019] to [0023], [0036], [0037], FIG. 7, etc.) JP-A-10-328368 ([0015], [0018], FIG. 3 etc.) JP 2000-24190 A ([0029], [0031], [0033], etc.) JP 2003-47705 A ([0017], FIG. 4 etc.)

  However, in the conventional techniques described in Patent Documents 1, 2, and 4, the cover member is provided with a structure for weakening the momentum of the game ball. Conversely, the cover member has a function of weakening the momentum of the game ball. It is a structure that depends only on the game nails and does not rely on game nails. In this case, since the momentum of the game ball cannot be sufficiently reduced, the burden on the game nail when the game ball collides cannot be reduced much. Further, in the prior art described in Patent Document 3, the game ball dropped from the cover member is made to collide with the game nail after weakening the momentum of the game ball with the structure (projection) provided on the cover member. The momentum has been further weakened. However, even if the momentum of the game ball is once weakened, the momentum increases again when the game ball falls from the cover member. Not. Therefore, the burden on the game nail cannot be reduced much.

  The present invention has been made in view of the above problems, and its purpose is to reduce the burden on the game nail near the lower end of the game ball rolling passage by reliably reducing the momentum of the game ball. It is to provide a gaming machine that can be used.

  In order to solve the above-mentioned problem, the invention according to claim 1, after the game ball launched by the launching device passes through the launch path generated between the inner rail and the outer rail on the game board surface, The player enters the game area via a ball return prevention member present at the end of the launch path, and the game ball that has entered the game area enters a winning opening provided in the game area to obtain a prize. A gaming machine comprising a frame-shaped cover member provided at an approximately central portion of the gaming area and provided with an opening for exposing a display area of a display device disposed on a rear side of the gaming board; A plurality of game nails that are implanted in the game area and change the direction of a game ball flowing down in the game area, and the upper left portion of the cover member has a substantially arc shape in a front view substantially parallel to the outer rail. And is formed on the left side from the center of the cover member. A first surface located on the upstream side of the gaming ball rolling passage and a second surface located on the downstream side of the gaming ball rolling passage on the gaming ball rolling passage that becomes lower according to The plurality of game nails have protrusions having a substantially triangular cross section in which the area of one surface is larger than the area of the second surface, and the plurality of game nails are arranged in a region on the right side of the ball return prevention member. A plurality of ball return prevention nails that are planted so as to be orthogonal to the direction in which the movement path extends, and that prevent the game balls that have passed therethrough from returning to the firing path, and the plurality of ball return prevention nails A guide nail that guides the game ball that has reached the right side of the plurality of ball return prevention nails onto the game ball rolling passage, and is implanted in a region on the left side and above the tip of the protrusion, Rolls on the ball rolling path, passes over the first surface of the protrusion, and jumps up A speed reduction nail that weakens the momentum of the game ball by the collision of the game ball, and the distance between the tip of the protrusion and the speed reduction nail is greater than 1.0 times the diameter of the game ball and less than 1.5 times And the length of the line connecting the speed-reducing nail and the game ball rolling passage perpendicular to the extension line when the first surface of the protrusion is viewed from the front is 1 of the diameter of the game ball. The gist of the game machine is characterized in that the distance between the intersection of the line segment and the extension line and the speed-down nail is less than 1.0 times the diameter of the game ball.

  Therefore, according to the first aspect of the present invention, the game ball that has passed over the ball return prevention nail is guided by the guide nail onto the game ball rolling passage at the upper left of the cover member, and on the game ball rolling passage. The momentum is weakened by colliding with the protrusion provided on the. Furthermore, since the speed reduction nail is planted in a region on the left side and above the tip of the protrusion, the game ball that has bounced and collided with the protrusion can be made to collide with the speed reduction nail. Be weakened. As a result, since the momentum of the game ball is surely weakened, it is possible to reduce the burden on the game nail when the game ball falls from the downstream end of the game ball rolling passage and collides with the game nail. Therefore, it is possible to prevent the game nail from being damaged due to the impact at the time of the collision, and it is also possible to prevent problems caused by the game nail being damaged.

  Further, the distance between the protrusion and the speed reduction nail is greater than 1.0 times the diameter of the game ball and 1.5 times or less. If the distance between the protrusion and the speed reduction nail is 1.0 times or less the diameter of the game ball, the game ball cannot pass between the protrusion and the speed reduction nail. On the other hand, if the distance between the protrusion and the speed reduction nail is larger than 1.5 times the diameter of the game ball, it becomes difficult for the game ball to collide with the speed reduction nail, making it difficult to weaken the momentum of the game ball with the speed reduction nail. Become. Also, even if the speed of the game ball is weakened by the speed reduction nail, the power of the game ball becomes stronger again when falling on the game ball rolling passage, so that the effect obtained even if the game ball collides with the speed reduction nail Will become smaller.

  Here, examples of the winning opening include a starting winning port of the starting winning device, other winning ports of the normal winning device, and a large winning port of the large winning device. It should be noted that there may be only one winning opening through which game balls enter or a plurality of winning holes may be provided.

  According to a second aspect of the present invention, in the first aspect, the game ball rolling passage includes a first protrusion that allows a game ball that has rolled in the game ball rolling passage to jump up, and the first protrusion. A plurality of the decelerations that are arranged at locations spaced apart from the tip of the ball by a distance that is greater than 1.0 times the diameter of the game ball and less than 1.5 times, and that the game ball that is thrown up by the first protrusion collides with A nail and a game ball which is disposed substantially directly below the speed reduction nail on the downstream side of the game ball rolling passage by an amount substantially equal to the diameter of the game ball from the first protrusion, and has fallen in collision with the speed reduction nail. The gist is to have a second projecting portion that collides.

  Therefore, according to the second aspect of the present invention, after the game ball bounced up from the first protrusion collides with the speed reduction nail, it further falls and collides with the second protrusion. That is, since the momentum of the game ball can be weakened more reliably by causing the game ball to collide in the order of the first protrusion → the decelerating nail → the second protrusion, the game ball starts from the downstream end of the game ball rolling passage. When the ball falls and collides with the game nail, the burden on the game nail can be more reliably reduced. In addition, since a plurality of speed-reducing nails are arranged at a location separated from the first protrusion by a distance greater than 1.0 times the diameter of the game ball and not more than 1.5 times, it jumps up at the first protrusion. This makes it easier to hit the game ball against the speeding nail. Therefore, the momentum of the game ball can be weakened more reliably.

  In addition, since the second protrusion is arranged almost immediately below the speed reduction nail, it is easy to cause the game ball that collides with the speed reduction nail to fall to the second protrusion, and the momentum of the game ball is more reliably ensured. Be weakened. The first protrusion and the second protrusion may have different shapes or the same shape.

  The invention according to claim 3 is the game according to claim 1 or 2, wherein the protrusion is covered on the front upper left side of the cover member so as not to be visible from the front, and the game ball rolling passage is rolled. The gist of the invention is that a flip-up prevention plate is provided to prevent the ball from jumping forward.

  Therefore, according to the third aspect of the present invention, even when the game ball rolling on the game ball rolling path jumps forward, the game ball bounces back on the splash-up preventing plate and again enters the game ball rolling path. Led. Therefore, it is possible to prevent damage caused by the splashed game ball coming into contact with the display device or the like. In addition, by providing the flip-up prevention plate, it is possible to conceal a projection that does not look good so that it cannot be viewed from the front. It should be noted that if the front surface of the spring-up preventing plate is decorated, the appearance will be further improved.

  It is preferable that the splash prevention plate does not cover the plurality of ball return prevention nails, the guide nails, and the speed reduction nails. In this way, it is possible to show the player the complicated movement of the game ball that rebounds to the ball return prevention nail, the guide nail, and the speed reduction nail, so that the interest can be improved.

  As described in detail above, according to the first to third aspects of the present invention, by reducing the momentum of the game ball with certainty, the burden on the game nail in the vicinity of the lower end of the game ball rolling passage is reduced. It is possible to provide a gaming machine that can be used. In particular, according to claim 2, the momentum of the game ball can be weakened more reliably.

Hereinafter, an embodiment in which the present invention is embodied in a gaming board 11 of a gaming machine (pachinko machine) will be described with reference to the drawings.
(1) Configuration of the game board 11

  As shown in FIG. 1, an inner rail 13 a and an outer rail 13 b that divide the game area 12 are laid in a substantially circular shape on the game board surface 11 a of the game board 11. Further, a game ball A1 (see FIG. 6 and the like) launched by the launching device when an operation handle (not shown) is operated passes through the launch path 14 formed between the inner rail 13a and the outer rail 13b. It has become. Then, the game ball A1 that has passed through the launch path 14 spreads the ball return prevention member 15 present at the end portion of the launch path 14 and enters the game area 12, and flows down in the game area 12. . Further, a windmill 16 is disposed in the game area 12, and a plurality of game nails 41 are planted in almost the entire game area 12. The windmill 16 and each game nail 41 change the direction of the game ball A <b> 1 flowing down in the game area 12.

  As shown in FIG. 1, on the rear side of the game board 11, there is disposed a symbol display device 18 for performing a symbol variation game by variably displaying a plurality of types of symbols. Further, a center accessory 31 as a “cover member” is disposed at a substantially central portion of the game area 12. The center accessory 31 is a frame-like member for decorating the symbol display device 18. As shown in FIG. 2, FIG. 3, etc., the front surface of the synthetic resin accessory body 32 constituting the center accessory 31 is generally decorated, and a substantially rectangular shape is formed at the substantially central portion thereof. The opening 33 is provided. The opening 33 is formed corresponding to the size of the display area H so as to expose the display area H of the symbol display device 18. Further, a flange portion 34 that protrudes from the outer peripheral portion of the accessory main body 32 and comes into contact with the game area 12 when attached to the game board 11 is provided. And the center combination 31 is attached to the game board 11 by fixing the several location of the flange part 34 with the screw which is not shown in figure (refer FIG. 1).

  As shown in FIG. 1, the center bonus 31 is arranged in a state biased to the upper right of the game area 12, and the area of the installation area of the center bonus 31 including the opening 33 is the area of the game area 12. It accounts for about 65%. For this reason, most of the game balls A1 that have entered the game area 12 flow down the area on the left side of the center accessory 31. That is, the game area 12 in which the game ball A1 can flow is substantially limited to the upper side, the left side, and the lower side of the center accessory 31. Further, since the shortest distance between the center accessory 31 and the inner rail 13a is set to about twice the diameter of the game ball A1, the region where the distance between the center accessory 31 and the inner rail 13a is the shortest distance is , It is difficult to install an accessory (such as a windmill).

  A start winning device 22 in which a first start winning port 22a and a second starting winning port 22b are formed is disposed below the center accessory 31. A game ball A1 flowing down in the game area 12 can win a prize at the first start winning opening 22a and the second starting winning opening 22b. When the symbol display game 18 is started by the symbol display device 18 in response to the winning of the game ball A1 at the first start winning opening 22a, a predetermined number (three in this embodiment) of winning balls is paid out. It has come to be. Similarly, when the symbol change game is started by the symbol display device 18 triggered by the winning of the game ball A1 to the second start winning opening 22b, a predetermined number (four in this embodiment) of payout balls is paid out. It has come to be.

  As shown in FIG. 1, the second start winning opening 22b is a winning opening that is arranged directly below the first start winning opening 22a, and in which a normal electric accessory is integrally formed. The ordinary electric combination is composed of a pair of blade members 22c, and the game ball A1 is allowed to win the second start winning opening 22b by opening the second starting winning opening 22b by an exciting action of a solenoid (not shown). It is like that.

  Also, below the start winning device 22, a large winning device 24 having an opening / closing door that is opened and closed by a solenoid (not shown) is disposed. The big winning device 24 is configured to pay out a predetermined number (15 in this embodiment) of winning balls when a game ball wins a big winning opening. Further, in the game area 12, a lower left outside winning port 23 a and a lower left inner winning port 23 b are arranged on the left side of the big winning device 24. In the game area 12, a lower right outside winning port 23 c and a lower right inner winning port 23 d are arranged on the right side of the big winning device 24. These winning holes 23a, 23b, 23c, and 23d are designed to pay out a predetermined number (10 in this embodiment) of winning balls in response to winning of gaming balls. In the lowermost part of the game area 12 (the lower end portion of the inner rail 13a), an out port 25 for collecting the game balls A1 that have not won any of the winning ports 22, 23a to 23d, 24 is disposed. ing.

  As shown in FIG. 1 and the like, a gate 26 having a function of detecting the passage of the game ball A1 is integrally provided on the left side of the center accessory 31. The gate 26 is opened in the vertical direction, and the game ball A1 flowing down in the game area 12 can pass from above. Behind the gate 26 is provided a gate switch 27 (see FIGS. 9 and 10) for detecting the game ball A1 that has passed. A random number is acquired when the game ball A1 is detected by the gate switch 27, and the solenoid of the ordinary electric accessory is driven based on whether or not the acquired random number is a predetermined random value. Since the pair of blade members 22c of the ordinary electric accessory is opened by such opening determination, the game ball A1 can easily win the second start winning opening 22b.

  As shown in FIG. 1, FIG. 2, and the like, the lower right portion of the center accessory 31 is provided with a visible display portion indicating a winning symbol “◯” and a visible display portion indicating a lost symbol “X”. A normal symbol display unit 35 is provided. In the normal symbol display unit 35, when the game ball A1 is detected by the gate switch 27, a normal symbol variation game in which the normal symbol is changed and displayed ("○" and "x" are alternately lit) is started. As a result of the normal symbol variation game, a normal symbol indicating the result of the random number lottery is displayed (one visible display portion is lit). When the winning symbol is derived (when the normal symbol variation game is won), the solenoid of the ordinary electric accessory is driven for a predetermined time, and the pair of blade members 22c are opened.

  In addition, a normal symbol holding display device F is disposed at the upper right of the normal symbol display unit 35. The normal symbol hold display device F is constituted by a plurality of (four) light emitting means including a first hold lamp, a second hold lamp, a third hold lamp, and a fourth hold lamp. The holding lamp is turned on when the game ball A1 (ordinary symbol holding ball) stored by the passage of the gate 26 is present, and is turned off when the normal symbol holding ball does not exist. Each holding lamp is for indicating the number of normal symbol holding balls (the number of normal symbol holding balls). For example, when there are two normal symbol holding balls, two holding lamps are lit.

Here, the “ordinary symbol reserved ball count” is a value stored in the range of a predetermined maximum value (4 in the present embodiment) of the number of game balls A1 that have passed through the gate 26. The number of normal symbol reserved balls is “+1” when the game ball A1 passes to the gate 26, and is “−1” when the release determination is made.
(2) Configuration of the upper left part of the center accessory 31

  As shown in FIGS. 1 to 8, the upper left portion of the center accessory 31 is formed in a substantially arc shape in front view substantially parallel to the outer rail 13 b, and goes to the left from the center of the center accessory 31. An arcuate arcuate game ball rolling passage 91 that becomes lower in accordance with this is provided. The game ball rolling passage 91 flows down to the left side of the center accessory 31 along the game ball rolling passage 91 after the game ball A1 is launched at the upper position of the gaming area 12 and flows down to the game ball rolling passage 91. It is designed to guide you.

  As shown in FIGS. 3 and 6 to 8, the upstream protrusion 92, the first protrusion 93, and the second protrusion 94 are disposed on the game ball rolling passage 91 in a state of being separated from each other. ing. The upstream protrusion 92, the first protrusion 93, and the second protrusion 94 are for jumping up the game ball A <b> 1 that has rolled on the game ball rolling passage 91. The upstream protrusion 92 is a protrusion arranged on the most upstream side in the game ball rolling passage 91. The first protrusion 93 is disposed downstream of the game ball rolling passage 91 by a diameter corresponding to approximately four game balls A <b> 1 from the upstream protrusion 92. The second protrusion 94 is arranged on the downstream side of the game ball rolling passage 91 by an amount substantially equal to the diameter of the game ball A1 from the first protrusion 93. Further, the upstream protrusion 92, the first protrusion 93, and the second protrusion 94 are positioned on the first surface 95 located on the upstream side of the game ball rolling passage 91 and on the downstream side of the game ball rolling passage 91. The second surface 96 has a substantially triangular cross section. In each protrusion 92, 93, 94, the area of the first surface 95 is larger than the area of the second surface 96. Further, the protruding amount of the upstream protrusion 92 from the game ball rolling passage 91 is set to about one-seventh of the diameter of the game ball A1, and the first protrusion 93 and the first protrusion 93 from the game ball rolling passage 91 are set. The protrusion amount of the two protrusions 94 is set to about 1/6 of the diameter of the game ball A1. Furthermore, the length of each protrusion 92,93,94 in the depth direction (direction orthogonal to the game ball rolling passage 91) is equal to each other. The first protrusion 93 and the second protrusion 94 have the same shape. Further, the inclination angle with respect to the horizontal surface of the first surface 95 of the first protrusion 93 is smaller than the inclination angle of the first surface 95 of the upstream protrusion 92 with respect to the horizontal surface, and the second protrusion The inclination angle with respect to the horizontal plane of the first surface 95 included in 94 is smaller than the inclination angle with respect to the horizontal plane of the first surface 95 included in the first protrusion 93. In other words, the inclination angle of the first surface 95 with respect to the horizontal plane becomes larger as going to the protrusion on the downstream side.

As shown in FIGS. 1 to 5, a flip-up preventing plate 97 extending along the game ball rolling passage 91 is attached to the front left side of the center accessory 31. The splash prevention plate 97 is for preventing the game ball A1 rolling in the game ball rolling passage 91 from jumping forward. The flip-up prevention plate 97 covers the protrusions 92, 93, 94 so that they cannot be seen from the front. That is, the amount of protrusion of the splash prevention plate 97 from the game ball rolling passage 91 in the direction away from the center accessory 31 is greater than the amount of protrusion of each of the protrusions 92, 93, 94 from the game ball rolling passage 91. Is also getting bigger. Further, the length in the longitudinal direction of the flip-up preventing plate 97 is longer than the distance from the upstream protrusion 92 to the second protrusion 94. In addition, decorations such as letters and pictures are provided on the front surface of the flip-up prevention plate 97. Further, light emission for causing a light emitting diode (light emitting means) (not shown) behind the splash prevention plate 97 to emit light at a position on the back side (rear side) of each protrusion 92, 93, 94 in the center accessory 31. A control board 98 is provided (see FIG. 2).
(3) Arrangement of game nails 41

  As shown in FIGS. 1 to 5, a part of each game nail 41 is a ball return prevention nail 42, a guide nail 43, and speed reduction nails 44 a, 44 b, 44 c.

More specifically, the speed reduction nail 44a in the vicinity of the upstream protrusion 92 is on the left side and above the tip of the upstream protrusion 92 (specifically, the connection portion between the first surface 95 and the second surface 96). One is planted in this area. The speed reduction nail 44a rolls on the game ball rolling passage 91, and weakens the momentum of the game ball A1 by the collision of the game ball A1 that has passed through the first surface 95 of the upstream projection 92 and is bounced up. It is like that. Further, the speed reduction nails 44b and 44c in the vicinity of the protrusions 93 and 94 are on the left side and above the tip of the first protrusion 93 (specifically, the connection portion between the first surface 95 and the second surface 96). In the region above the tip of the second protrusion 94 (specifically, the connecting portion between the first surface 95 and the second surface 96). That is, the second projecting portion 94 is disposed substantially immediately below the speed reduction nails 44b and 44c. The speed reduction nail 44b, 44c rolls on the game ball rolling passage 91, and the momentum of the game ball A1 is generated by the collision of the game ball A1 that has passed through the first surface 95 of the first protrusion 93 and bounced up. Has come to weaken. The game ball A1 that has collided with the deceleration nails 44b and 44c falls and collides with the second protrusion 94.

Of the three movable body covers 54, the two movable body covers 54 are respectively disposed below the three effect movable bodies 53, and the remaining one movable body cover 54 is disposed between the two movable body covers 54. Has been. Each movable body cover 54 and the stage 81 constitute a game ball passage through which the game ball A1 passes. Further, since the lower surface of each movable body cover 54 has a curved undulation shape as a whole, the movement of the game ball A1 falling from the stage 81 to the game area 12 can be changed.

  Each effect movable body 53 can swing in the vertical direction via a rotation shaft 55 on the upper side of the unit main body 52. Each effect movable body 53 includes a light emitting portion 56, and the light emitting portion 56 is formed by a light emitting diode (not shown) of an LED substrate 57 disposed on the back side of the light emitting portion 56 in the effect movable body 53. Lights up and blinks.

  As shown in FIGS. 16 to 19 and the like, each effect movable body 53 swings as the movable body motor 58 built in the unit main body 52 rotates. More specifically, a motor gear 59 is attached to the rotation shaft of the movable body motor 58, and the first rib 60 is provided on the motor gear 59. The effect movable body 53 is provided with an arm 61 extending in the vertical direction so as to be rotatable via a rotation shaft 61 a, and a second rib 62 protruding toward the motor gear 59 is provided at the lower end of the arm 61. Is formed. Then, when the movable body motor 58 and the motor gear 59 rotate, the first rib 60 provided on the motor gear 59 pushes down the second rib 62, so that one of the effect movable bodies 53 of each effect movable body 53 swings. It moves (refer FIG.18 and FIG.21 (a), (b)). Accordingly, the doll 63 that is swingably attached to the production movable body 53 is suspended from the production movable body 53 by its own weight (see FIGS. 18 and 21A). ). Further, a spring 64 having one end attached to the arm 61 and the other end attached to the unit main body 52 extends. After that, when the movable body motor 58 and the motor gear 59 further rotate and the first rib 60 moves away from the second rib 62, the effect movable body 53 and the doll 63 are returned to the original positions by the restoring force of the spring 64. (See FIGS. 20A and 20B). The mechanism for swinging the other effect movable body 53 is the same as the mechanism movable body 53 that swings by the first rib 60 of the motor gear 59.

Specifically, in the position detection sensor 69, the first rib 60 is not in contact with the second rib 62, and the light from the light emitting portion is blocked by the light blocking plate 67, so that the light receiving portion cannot receive light. In this case (see FIGS. 22A and 22B), the light shielding plate 67 is detected (turned on). In this case, the position detection sensor 69 outputs a detection signal indicating that the effect movable body 53 is in the initial position before swinging to a CPU (central processing unit) of a general control board (not shown) provided in the pachinko machine. To do. On the other hand, when the light receiving unit can receive light from the light emitting unit, the position detection sensor 69 does not detect the light shielding plate 67 (becomes off) and does not output a detection signal.

  Next, the movement of the game ball A1 passing through the game ball rolling passage 91 will be described.

  For example, when the game ball A <b> 1 that is launched by the launching device and enters the game area 12 passes over the ball return prevention nail 42, the game ball A <b> 1 reaches near the upper center of the center accessory 31. The game ball A1 is guided onto the game ball rolling passage 91 while colliding with the guide nail 43 and the like.

  When the game ball A1 flows down on the game ball rolling passage 91 and reaches the upstream protrusion 92 (see FIGS. 6 and 7A), the game ball A1 collides with the upstream protrusion 92. Momentum is weakened. Further, the game ball A1 passes over the first surface 95 of the upstream projection 92 and is bounced up to collide with the speed reduction nail 44a (see FIG. 7B). As a result, the momentum of the game ball A1 is weakened and the direction of the game ball A1 is changed, so that the game ball A1 falls into a region on the downstream side of the upstream protrusion 92 in the game ball rolling passage 91. And game ball A1 flows down on game ball rolling passage 91 again.

  Next, when the game ball A1 flows down on the game ball rolling passage 91 and reaches the first protrusion 93 (see FIG. 6), the game ball A1 collides with the first protrusion 93 to weaken the momentum. It is done. Further, the game ball A1 passes over the first surface 95 of the first protrusion 93 and is bounced up to collide with the speed reduction nails 44b and 44c (see FIG. 8A). As a result, the momentum of the game ball A1 is weakened and the direction of the game ball A1 is changed, and the game ball A1 falls and collides with the second protrusion 94 to further weaken the momentum (FIG. 8B). reference). Furthermore, the game ball A <b> 1 is bounced up after passing over the first surface 95 of the second protrusion 94, and falls to the downstream side of the second protrusion 94 in the game ball rolling passage 91. Thereafter, the game ball A1 again flows down on the game ball rolling passage 91 and falls from the left end portion (downstream end portion) of the game ball rolling passage 91.

  Next, the movement of the game ball A1 flowing down the left side of the center accessory 31 will be described.

  The game ball A1 that has flowed down to the vicinity of the left end portion of the center accessory 31 in the game area 12 by dropping from the left end portion of the game ball rolling passage 91 or the like is 1. 1. path to enter gate 26; 2. a route entering the detour route 76 from the first ball entrance 72; It passes through one of the paths on the left side of the gate 26. 1. When the path is taken, the game ball A1 flows through the area below the gate 26 in the game area 12 after passing through the gate 26 (see FIG. 10A). Note that when the game ball A1 reaches the area below the gate 26 and contacts the first ball outlet side protrusion 73a, the direction is changed and the left ball flows downward, but the first ball outlet side protrusion 73a. If it does not touch, it will flow down. On the other hand, 2. In this case, the game ball A1 enters the detour path 76 from the first ball inlet 72, passes through the detour path 76, and is guided from the first ball outlet 73 to the area below the gate 26 (FIG. 9). reference). At this time, the game ball A1 is guided in the left direction by the first ball outlet side protruding piece 73a and can collide with the guide nail 45 (see FIG. 10A). When the game ball A1 collides with the guide nail 45, the direction of the game ball A1 is changed by the guide nail 45 and is guided to the second ball entrance 74 side. 3. When the path of the game ball A1 is taken, the game ball A1 flows down in the game area 12 while changing the direction by the game nail 41. And if it collides with the guidance nail 45, direction will be changed by the guidance nail 45 and the possibility that the game ball A1 will be guided to the 2nd ball entrance 74 side becomes high.

  After that, ~ 3. When the game ball A1 that has passed the path reaches the second ball inlet-side protruding piece 74a, the game ball A1 rolls on the second ball inlet-side protruding piece 74a and passes from the second ball inlet 74 to the ball guide path. Enter 75 (see FIG. 12). The game ball A <b> 1 moves downward in the ball guide passage 75 and is guided onto the rolling surface 82 of the stage 81 from the ball outlet 79.

  Next, a method for distributing the game balls A1 by the stage 81 will be described.

  As shown in FIG. 14, the game ball A1 guided onto the rolling surface 82 repeats acceleration / deceleration as it passes through the convex portion 83, the left concave portion 84a, and the right concave portion 84b, while rolling the rolling surface 82. Move back and forth in the left-right direction. When the momentum of the game ball A1 is lost, the game ball A1 is discharged to the game area 12 from any one of the convex portion discharge portion 85, the left concave portion 84a, and the right concave portion 84b. Specifically, the game ball A1 that has reached the convex portion discharge portion 85 enters the ball path via the drop hole 86 and is discharged from the discharge port 88 to the game area 12. As shown in FIG. 1, the game ball A1 guided to the drop hole 86 falls from directly above the start winning device 22, and therefore enters the first start winning port 22a of the start winning device 22 with high probability. . On the other hand, the game ball A1 guided to the left recess 84a and the right recess 84b is directly discharged to the game area 12. As shown in FIG. 14, even when the game ball A1 flowing down the game area 12 bounces back to the game nail 41 and is guided onto the rolling surface 82, the game ball A1 rolls on the rolling surface 82. Then, the light is discharged into the game area 12 from any one of the convex discharge portion 85, the right concave portion 84b, and the right concave portion 84b.

  Therefore, according to the present embodiment, the following effects can be obtained.

  (1) In the pachinko machine according to the present embodiment, the game ball A1 guided on the game ball rolling passage 91 includes an upstream projection 92, a first projection 93, and the like provided on the game ball rolling passage 91. By colliding with the second protrusion 94, the momentum of the game ball A1 is weakened. Further, the speed reduction nail 44a is planted in a region on the left side and above the tip of the upstream protrusion 92, and the speed reduction nails 44b and 44c are planted in a region on the left side and above the tip of the first projection 93. Yes. For this reason, the game ball A1 that has collided with the upstream protrusion 92 and the second protrusion 94 can be caused to collide with the speed-down nails 44a to 44c, and the momentum of the game ball A1 is further weakened by the collision. As a result, the momentum of the game ball A1 is surely weakened, so that the game ball A1 falls from the downstream end of the game ball rolling passage 91 and hits a specific game nail 41a (see FIG. 1). The burden on the nail 41a can be reduced. Therefore, it is possible to prevent the game nail 41a from being damaged due to the impact at the time of the collision, and it is also possible to prevent problems caused by the game nail 41a being damaged.

  (2) In the present embodiment, the first protrusion 93 is disposed on the downstream side of the game ball rolling passage 91 by a diameter corresponding to approximately four diameters of the game ball A1 from the upstream protrusion 92, and the second protrusion 94 is arranged on the downstream side of the game ball rolling passage 91 by the approximate diameter of the game ball A1 from the first protrusion 93. That is, the protrusions 92, 93, 94 are not arranged at equal intervals. This complicates the movement of the game ball A1 that has collided with the protrusions 92, 93, 94. As a result, the player becomes interested in the movement of the game ball A1 passing through the game ball rolling passage 91, so that the player can be given a fresh taste and the entertainment can be improved.

  (3) As another method for suppressing the burden on the game nail 41a, it is conceivable to increase the route of the game ball A1, and for that purpose, it is necessary to increase the game nail 41. Further, since the diameter of the game ball A1 is 11.0 mm, the interval between the game nails 41 needs to be equal to or larger than the diameter of the game ball A1. However, when the area of the installation area of the center accessory 31 occupies about 65% of the area of the game area 12 as in the present embodiment, the space where the game nail 41 can be implanted in the game area 12 is limited. Therefore, it is difficult to increase the route of the game ball A1. Therefore, in the present embodiment, the protrusions 92, 93, and 94 are provided on the game ball rolling passage 91, and the speed reduction nail 44a to 44c is implanted in the game area 12, thereby reducing the momentum of the game ball A1. Therefore, the burden on the game nail 41a can be suppressed without increasing the game nail 41.

  In addition, you may change embodiment of this invention as follows.

  In the above embodiment, the three protrusions 92, 93, 94 are provided on the game ball rolling passage 91, but the number of protrusions may be two or less, or four or more. May be.

  In the above embodiment, only one set of the first protrusion 93 and the second protrusion 94 is arranged on the game ball rolling passage 91, but a plurality of sets may be arranged.

  In the above embodiment, the speed reduction nail 44a is planted in the area on the left side and above the tip of the upstream protrusion 92, and the speed reduction nails 44b and 44c are in the area on the left side and above the tip of the first protrusion 93. It was planted. However, speed reduction nails may also be planted in a region on the left side and above the tip of the second protrusion 94. In this way, the momentum of the game ball A1 can also be weakened by the collision of the game ball A1 with the speed-down nail planted in the region on the left side and above the tip of the second protrusion 94.
