In addition, the lower tray 26a has a function of storing game balls that become surplus in the upper tray 25a.

  FIG. 2 is a front view of the inner frame 13. The inner frame 13 is mainly composed of a resin base 31 whose outer shape is substantially the same as that of the outer frame 11. A substantially elliptical window hole 32 is formed at the center of the resin base 31. A game board 34 is detachably attached to the resin base 31 so as to be exposed to the front side of the inner frame 13 through the window hole 32. The game board 34 is attached in an upright state, and the front surface thereof faces the front of the pachinko machine 10.

  On the front surface of the game board 34, a game area PT is defined by guide rail portions 35 and 36 attached to the front surface of the game board 34 and a peripheral portion 32 a of the window hole 32 in the resin base 31. A game ball is guided to the game area PT by the guide path 37 formed by the guide rail portions 35 and 36, and the guided game ball flows down in the game area PT.

  A game ball launched by the game ball launching mechanism 38 is supplied to the game area PT. The game ball launching mechanism 38 is provided below the window hole 32 in the resin base 31. The game ball launching mechanism 38 is supplied onto the launch rail 38a extending toward the guide passage 37, a ball feeding device 38b for feeding the game ball stored in the upper plate 25a onto the launch rail 38a, and the launch rail 38a. And a solenoid 38c, which is an electric actuator for firing the game ball toward the guide passage 37. When the firing operation device 39 (see FIG. 1) provided at the lower right corner of the front door frame 14 is rotated, the solenoid 38c is driven and controlled, and a game ball is launched. The game ball launching mechanism 38 is disposed at a position biased to the right in the lower part of the resin base 31. Then, a game ball is launched from the game ball launching mechanism 38 toward the upper left.

  Incidentally, as shown in FIG. 1, the launch operation device 39 includes an operation base portion 39a provided to project forward, and an operation handle 39b provided to be rotatably supported by the operation base portion 39a. Thus, the operating intensity of the game ball from the game ball launching mechanism 38 is adjusted by rotating the operation handle 39b.

The inner rail portion 35 exists from the lower right corner side to the upper left corner side of the game board 34 at a position inside the outer rail portion 36. The inner rail portion 35 is formed in an arc shape that is convex outward like the outer rail portion 36, and the curvature of the inner rail portion 35 is the same as or substantially the same as the curvature of the outer rail portion 36. .

  The distance between the inner rail portion 35 and the outer rail portion 36 is larger than one game ball, specifically, a distance corresponding to two game balls. Here, the diameter of the game ball used in the pachinko machine 10 is 11 mm. Therefore, the distance between the inner rail part 35 and the outer rail part 36 is 22 mm. However, it is not limited to this, and the distance between the inner rail portion 35 and the outer rail portion 36 is arbitrary as long as it is equal to or longer than one game ball. For example, the distance is shorter than two game balls. The distance may be longer than two game balls.

  Since the distance between the inner rail portion 35 and the outer rail portion 36 is set as described above, the guide passage 37 is formed as described above. The ball entrance 37 a of the guide passage 37 is present at the position of the lower end of the outer rail portion 36, and the position is on the lower center side of the game board 34. The ball entrance 37 a is present on the front side of the game ball launching mechanism 38 in which the launch rail 38 a is extended in the launch direction of the game ball, whereby the game ball launched from the game ball launching mechanism 38 is placed in the guide passage 37. Can be introduced.

  The game ball introduced into the guide passage 37 moves upward along the inner wall portion of the outer rail portion 36. If the firing intensity of the game ball launched by the game ball launching mechanism 38 is equal to or greater than a predetermined strength, the game ball passes through the ball outlet 37 b of the guide passage 37. The ball outlet 37 b of the guide passage 37 is present at the position of the upper end of the inner rail portion 35, and the position is the upper left corner of the game board 34. This position is the upper left corner of the game area PT. Therefore, in a situation where a game ball is being fired by the game ball launch mechanism 38 with a firing strength of a predetermined strength or more, a game ball is introduced into the game area PT from the upper left corner of the game area PT. It becomes.

  The launch rail 38a of the game ball launching mechanism 38 and the ball entrance 37a of the guide passage 37 are laterally separated from each other, and a foul ball collection unit 33 is provided therebetween. The foul ball collection unit 33 is formed to open upward, and is a game ball that has been launched from the game ball launching mechanism 38 and has not reached the guide passage 37 or a game ball that has flowed back through the guide passage 37. Is collected by the foul ball collecting unit 33. The foul ball collection unit 33 communicates with the lower plate 26a, and the game balls collected by the foul ball collection unit 33 are discharged to the lower plate 26a.

  A configuration in the game area PT will be described. FIG. 3 is a front view of the game board 34. The game board 34 has a plurality of large and small openings penetrating in the front-rear direction. Each opening is provided with a general winning port 41, a special electricity winning device 42, a first operating port 43, a second operating port 44, a through gate 45, a variable display unit 46, a special figure unit 47, a universal figure unit 48, and the like. ing.

  Even if a ball enters the through gate 45, the game ball is not paid out. On the other hand, when a ball enters the general winning port 41, the special electricity winning device 42, the first operating port 43 and the second operating port 44, a predetermined number of game balls are paid out. Specifically, with respect to the number of prize balls, when a ball enters the first operation port 43 or a ball enters the second operation port 44, three prize balls are paid out. When a ball is entered into the general winning opening 41, 10 prize balls are paid out. When a ball enters the special electricity prize winning device 42, 15 prize balls are paid out. Executed.

  The number of prize balls may be arbitrary. For example, the second operation port 44 may have a smaller number of prize balls than the first operation port 43, and the second operation port 44 may have a first operation port. The number of prize balls may be larger than 43.

  In addition, an out port 49 is provided at the lowermost part of the game board 34, and game balls that have not entered various winning ports etc. are discharged from the game area PT through the out port 49. In addition, the game board 34 is provided with a number of nails 51 for appropriately dispersing and adjusting the falling direction of the game ball, and various members such as a windmill.

  Here, the entry ball means that the game ball passes through a predetermined opening, and is not only a mode of being discharged from the game area PT after passing through the opening, but also from the game area PT after passing through the opening. A mode in which the game area PT continues to flow down without being discharged is also included. However, in the following description, in order to clearly distinguish the game ball from entering the out port 49, the general winning port 41, the special electricity winning device 42, the first operating port 43, the second operating port 44, and the through gate 45.

  A through gate 45 is provided on the upstream side in the flow direction of the game ball from the second operation port 44. The through gate 45 has a through-hole (not shown) penetrating in the vertical direction, and a game ball won in the through gate 45 flows down the game area PT after winning. As a result, the game ball that has won the through gate 45 can win the second operating port 44.

  Based on the winning of the through gate 45, the common utility 44 a of the second operating port 44 is switched from the closed state to the open state. Specifically, an internal lottery is performed with a winning at the through gate 45 as a trigger, and a normal display of the general-purpose unit 48 provided at the lower right corner, which is a region where the game ball does not pass in the game region PT. The change display of the pattern is performed in the part 48a. Then, when the result of the internal lottery is the electrification opening winning, the stop result corresponding to the result is displayed, and the fluctuation display of the general map display section 48a is finished, the state shifts to the public power open state. In the public power open state, the public power utility 44a is opened in a predetermined manner.

  The general map display unit 48a is configured by a segment display in which a plurality of segment light emitting units are arranged in a predetermined manner, but is not limited to this, and is not limited to this. A liquid crystal display device, an organic EL display device , Or other types of display devices such as CRT or dot matrix display. In addition, as a pattern variably displayed on the general map display unit 48a, a configuration in which a plurality of types of characters are variably displayed, a configuration in which a plurality of types of symbols are variably displayed, a configuration in which a plurality of types of characters are variably displayed or A configuration in which a plurality of colors are switched and displayed is conceivable.

  In the universal map unit 48, a universal map hold display section 48b is provided at a position adjacent to the universal map display section 48a. The maximum number of game balls won in the through gate 45 is reserved, and the reserved number is displayed by turning on the general-purpose hold display section 48b.

  A lottery is performed with the winning of the first working port 43 or the second working port 44 as a trigger. Then, the lottery result is clearly shown through display effects in the symbol display device 52 of the special figure unit 47 and the variable display unit 46.

  Specifically, the special figure unit 47 is provided with a special figure display unit 47a. The display area of the special figure display unit 47 a is narrower than the display surface of the symbol display device 52. In the special figure display unit 47a, a winning lottery is performed by using a winning at the first operating port 43 or a winning at the second operating port 44 as a trigger, thereby performing a variation display or a predetermined display of the pattern. Then, a result corresponding to the lottery result is displayed. The special figure display unit 47a is configured by a segment display in which a plurality of segment light emitting units are arranged in a predetermined manner, but is not limited thereto, and is not limited thereto. A liquid crystal display device, an organic EL display device , Or other types of display devices such as CRT or dot matrix display.

  In the special figure unit 47, a special figure holding display part 47b is provided at a position adjacent to the special figure display part 47a. The number of game balls won in the first operation port 43 or the second operation port 44 is reserved up to a maximum of four, and the reserved number is displayed by lighting the special figure reservation display section 47b.

  In detail, the symbol display device 52 is configured as a liquid crystal display device including a liquid crystal display, and display contents are controlled by a display control device described later. The symbol display device 52 is not limited to a liquid crystal display device, and may be a plasma display device, an organic EL display device, or another display device having a display surface such as a CRT, and is a dot matrix display. May be.

  In the symbol display device 52, when the special symbol display unit 47a displays a variation or a predetermined display of the symbol based on the winning in the first operating port 43 or the winning in the second operating port 44, the symbol is displayed accordingly. A variable display or a predetermined display is performed. For example, on the display surface of the symbol display device 52, three symbol rows of upper, middle, and lower rows are set as a plurality of display areas, and the main symbols to which the numbers “1” to “9” are attached in each symbol row. Are scrolled and displayed in an ascending or descending order. In this scroll display, the scroll display in all the symbol sequences is started first, and the display is switched from the scroll display to the standby display in the order of the upper symbol sequence → the lower symbol sequence → the middle symbol sequence. The process ends with the symbols still displayed. For example, in the game times in which the game result is a jackpot result, a predetermined combination of symbols is stopped and displayed on the active line set in advance on the display surface of the symbol display device 52.

  In addition, the symbol display device 52 performs not only a display effect triggered by winning a prize to the first operating port 43 or the second operating port 44 but also a display effect in the opening / closing execution mode that shifts after winning the winning combination. Is called. In addition, based on the winning at any one of the operation ports 43 and 44, the display is started on the special symbol display unit 47a and the symbol display device 52, and a predetermined result is displayed until the game is completed. Equivalent to times. Further, the variation display mode of the symbols in the symbol display device 52 is not limited to the above, but is arbitrary, the number of symbol columns, the direction of symbol variation display in the symbol columns, the number of symbols in each symbol column, etc. Can be appropriately changed. Further, the pattern that is variably displayed on the symbol display device 52 is not limited to the above-described pattern. For example, only a number may be variably displayed as the pattern.

  When the big win is won in the winning lottery based on the winning to the first operating port 43 or the winning to the second operating port 44, the mode shifts to the opening / closing execution mode in which the special electric winning device 42 can be won. The special electric prize winning device 42 is provided with a large winning opening (not shown) that leads to the back side of the game board 34, and an open / close door 42a that opens and closes the special winning opening. The open / close door 42a is arranged in either a closed state or an open state. Specifically, the open / close door 42a is normally in a closed state in which a game ball cannot be won, and can be switched to an open state in which a game ball can win when winning the transition to the open / close execution mode in the internal lottery. It has become. Incidentally, the opening / closing execution mode is a mode that shifts when a hit result is obtained. Note that, in the closed state, winning may not be impossible, but it may be configured such that winning is less likely to occur than in the open state.

<Return ball prevention unit 61, 71>
Here, as already described, the game ball launched from the game ball launching mechanism 38 passes through the guide passage 37 and is led out to the game area PT. The ball exit 37b of the guide path 37 temporarily enters the game area PT.

Therefore, in a situation where an external force from the game ball is not applied to the return ball prevention pieces 63 and 73, the base portions 68 and 78 are located at the base portions 68 and 78 at the rotation positions of the return ball prevention pieces 63 and 73. It becomes the rotation position which becomes lower than.

  The rotation range of the return ball preventing pieces 63 and 73 is limited to a predetermined range by the pedestal portions 64 and 74 integrally formed with the base plate portions 65 and 75 of the base bodies 62 and 72. The pedestal portions 64 and 74 are formed so as to face the base portions 68 and 78 of the return ball preventing pieces 63 and 73 from the lead-out side of the game ball led out from the guide passage 37. In 74, positioning protrusions 64 a and 74 a are integrally formed on the surface facing the base portions 68 and 78. When the pedestal portions 64 and 74 are not formed, the return ball prevention pieces 63 and 73 are in a natural state where the metal pieces 68a and 78a of the base portions 68 and 78 are vertically downward with respect to the shaft holes 67 and 77. However, the surfaces of the base portions 68 and 78 facing the pedestal portions 64 and 74 come into contact with the positioning protrusions 64a and 74a at a midway position toward the natural position, thereby the shaft hole. Further rotation of the return ball preventing pieces 63, 73 is prevented at a position where the metal pieces 68a, 78a are in the lower left with respect to 67, 77. The position where the further rotation is prevented by the positioning protrusions 64a and 74a is the initial position of the return ball preventing pieces 63 and 73. When the return ball preventing pieces 63 and 73 are arranged at the initial positions, the ball receiving portions 69 and 79 do not stand in the vertical direction as shown by the solid line in FIG. The posture is inclined so as to extend to the upper right.

  When the return ball preventing pieces 63, 73 arranged at the initial position are rotated in the direction away from the positioning protrusions 64a, 74a, as shown by the two-dot chain lines in FIG. Contacts the upper end portions 64b and 74b of the pedestal portions 64 and 74, respectively. Thereby, the further rotation of the return ball preventing pieces 63 and 73 is prevented. This position is the rotation-side limit position of the return ball preventing pieces 63 and 73. When the return ball preventing pieces 63 and 73 are arranged at the rotation-side limit position, the ball receiving portions 69 and 79 are tilted to the right as compared with the initial position, but the shaft holes 67 and 77 still remain. The tilted posture is maintained so as to extend to the upper right with reference to.

  Incidentally, the pedestal portions 64 and 74 are formed to extend downward from the positions of the positioning protrusions 64a and 74a, and are reversed from the end portions of the base portions 68 and 78 on the side where the shaft holes 67 and 77 are formed. The pedestal portions 64 and 74 are opposed from the right side to the whole or substantially the entire surface of the pedestal portions 64 and 74 over the side end portions. This opposed state is maintained at all the rotational positions of the return ball preventing pieces 63 and 73, and the gap between the base portions 68 and 78 and the base portions 64 and 74 is less than the diameter of the game ball. . Thereby, it becomes possible to prevent a game ball from colliding with the base parts 68 and 78 from the game area PT side.

  As already described, the ball receiving portions 69 and 79 are formed to be smaller in thickness than the base portions 68 and 78 and have a thin plate shape. In this case, the left plate surface of the ball receiving portions 69 and 79 is continuous without a step with respect to the left surface opposite to the surface facing the pedestals 64 and 74 in the base portions 68 and 78. doing. However, the inclinations of these surfaces in a front view are different, and more specifically, the left plate surface of the ball receiving portions 69 and 79 is inclined to the left than the left surface of the base portions 68 and 78. Thereby, even if the game ball colliding with the left side surface of the ball receiving portion 69, 79 from the left of the ball receiving portion 69, 79 stops at the position of the ball receiving portion 69, 79, the game ball is The ball does not continue to stay at the position of the boundary between the ball receiving portions 69 and 79 and the base portions 68 and 78, and flows down smoothly in the lower left direction.

  As will be described in detail later, the ball receiving portions 69 and 79 can have a game ball collide with each of the left plate surface and the right plate surface, and with respect to each of the left plate surface and the right plate surface. Game balls can collide at the same time. On the other hand, the thickness dimension of the ball receiving portions 69 and 79 is against the collision of the game ball at least within the assumed general useful life (for example, 3 years) in relation to the hardness of the forming material. The return ball preventing pieces 63 and 73 are set so as not to be damaged. Specifically, the thickness dimensions of the ball receiving portions 69 and 79 are preferably 0.3 mm or more and 4 mm or less, more preferably 0.5 mm or more and 3 mm or less.

  As will be described in detail later, the return ball prevention pieces 63 and 73 allow the game ball to move in the direction opposite to the derived direction while allowing the game ball derived from the guide passage 37 to move forward in the derived direction. There is a need to stop. In this respect, the length dimension of the ball receiving portions 69 and 79 is such that when a game ball collides from the guide passage 37 side, the return ball prevention pieces 63 and 73 are limited from the initial position to the rotation side by external force from the game ball. It can be moved to a position, and it is set so that a game ball that has collided with the ball receiving portions 69 and 79 from the opposite direction is not moved to the guide passage 37 side. Specifically, the length dimension of the ball receiving portions 69 and 79 is preferably 5.5 mm or more and 40 mm or less which is the radius of the game ball, and is 11 mm or more and 25 mm or less which is the diameter of the game ball. The following is preferable.

  The position where the first return ball prevention unit 61 and the second return ball prevention unit 71 are provided will be described. In the following description, “first” is added to the head of the names of the members constituting the first return ball prevention unit 61, and “first” is added to the head of the names of the members constituting the second return ball prevention unit 71. 2 ”is added. FIG. 5 is an enlarged front view of the game board 34 showing an area where the first return ball prevention unit 61 and the second return ball prevention unit 71 are provided.

  First, the first return ball prevention unit 61 will be described. The first return ball prevention unit 61 is provided at a position ahead of the ball outlet 37b of the guide passage 37 in the direction in which the game ball is led out from the guide passage 37 and adjacent to the ball outlet 37b. . Specifically, the shaft portion (the first shaft member 66 and the first shaft hole 67) of the first return ball preventing piece 63 is located on the upper right side of the upper end portion of the inner rail portion 35, and the first base portion 68. The lower end portion is spaced from the upper end portion of the inner rail portion 35. However, the gap between the lower end portion of the first base portion 68 and the upper end portion of the inner rail portion 35 is a situation where the first return ball prevention piece 63 is disposed at any rotation position. Is less than the radius of the game ball, and it is impossible for the game ball to enter the gap.

  Since the shaft portion of the first return ball prevention piece 63 is set at the above position, the first ball receiving portion 69 of the first return ball prevention piece 63 is led out from the ball outlet 37b of the guide passage 37. It has entered the passage route. However, the tip end (free end) of the first ball receiving portion 69 is not in contact with the outer rail portion 36, and the tip end of the first ball receiving portion 69 and the outer rail portion 36 are separated from each other. In the situation where the first return ball prevention piece 63 is disposed at the initial position, the separated distance is less than the diameter of the game ball and greater than or equal to the radius of the game ball, and the first return ball prevention piece 63 rotates. It is larger than the diameter of the game ball in the situation where it is arranged at the moving limit position. In addition, when a game ball launched with the first launch strength or higher collides with the left side surface of the first ball receiving portion 69, the game ball is rotated from the initial position to the rotation side limit position by the external force of the game ball. A return ball prevention piece 63 is formed. Thereby, when the game ball is being fired with the first launch strength or higher, the game ball is led to the game area PT without being stopped by the first return ball prevention unit 61. On the other hand, even if the game ball collides with the right side surface of the first ball receiving portion 69, the game ball is prevented from moving toward the guide passage 37 by the first ball receiving portion 69. It becomes possible to prevent the inflow of game balls from the region PT side to the guide passage 37 side.

  When the first return ball preventing unit 61 performs the above function, the angle of the first ball receiving portion 69 at the initial position is set to 0 degrees when the first ball receiving portion 69 stands in the vertical direction. In the case where the first ball receiving portion 69 has a larger angle as it falls to the right side, it is preferably −10 degrees or more and 90 degrees or less, and is 0 degrees or more and 60 degrees or less. More preferably.

  The shortest distance between the first base portion 68 and the outer rail portion 36 in the situation where the first return ball prevention piece 63 is disposed at the initial position is shorter than twice the diameter of the game ball. Therefore, if a game ball is placed on the first base portion 68 and the next released game ball reaches the position of the ball outlet 37b of the guide passage 37, the game ball is not in the first base portion. Although it collides with the game ball placed on 68 from the upstream side, it does not directly collide with the first ball receiving portion 69 and the first base portion 68. In this case, both of the two game balls flow backward through the guide passage 37. As a result, it is possible to prevent the occurrence of an event in which the game balls whose strength has been weakened by the collision between the game balls in the guide passage 37 are led out to the game area PT as they are.

  Next, the second return ball prevention unit 71 will be described. The second return ball prevention unit 71 is provided at a position ahead of the first return ball prevention unit 61 in the direction in which the game ball is led out from the guide passage 37. In this case, the second ball receiving portion 79 of the second return ball preventing piece 73 is led out from the guide passage 37 and passes through the first return ball preventing unit 61 and further passes along the outer rail portion 36. It has entered the route. However, the tip (free end) of the second ball receiving portion 79 is not in contact with the outer rail portion 36, and the tip of the second ball receiving portion 79 and the outer rail portion 36 are separated from each other. In the situation where the second return ball prevention piece 73 is disposed at the initial position, the separated distance is less than the diameter of the game ball and greater than the radius of the game ball, and the second return ball prevention piece 73 rotates. In the situation where it is arranged at the side limit position, it is larger than the diameter of the game ball. In addition, when a game ball launched with a second launch strength or higher collides with the left side surface of the second ball receiving portion 79, the game ball is rotated from the initial position to the rotation limit position by the external force of the game ball. Two return ball prevention pieces 73 are formed. Thereby, when the game ball is being fired with the second launch strength or higher, the game ball moves to the front side in the moving direction without being stopped by the second return ball prevention unit 71. On the other hand, even if the game ball collides with the right side surface of the second ball receiving portion 79, the game ball is prevented from moving to the left by the second ball receiving portion 79. It is possible to prevent the game ball that has reached the right side of the ball prevention unit 71 from flowing backward to the first return ball prevention unit 61 side.

  In order for the second return ball prevention unit 71 to perform the above function, the angle of the second ball receiving portion 79 at the initial position is set to 0 degrees when the second ball receiving portion 79 stands up in the vertical direction. In the case where the second ball receiving portion 79 has a larger angle as it falls to the right side, it is preferably −20 degrees or more and 45 degrees or less, and −10 degrees or more and 30 degrees or less. It is more preferable that

  The shortest distance between the second base portion 78 and the outer rail portion 36 in the situation where the second return ball preventing piece 73 is disposed at the initial position is longer than twice the diameter of the game ball. If a game ball is placed on the second base portion 78 and the next released game ball reaches the position of the second return ball prevention piece 73, the game ball is placed on the second base portion 78. It does not collide with the game ball that is placed, but collides with the second ball receiving portion 79 from the left side. Accordingly, there is a possibility that the game ball led out from the guide passage 37 may directly collide with another game ball without colliding with the second return ball prevention piece 73 on the left side of the second return ball prevention piece 73. Reduced.

  The positional relationship of the second return ball prevention unit 71 with respect to the first return ball prevention unit 61 will be described. The lower end of the combination of the second return ball prevention piece 73 and the second pedestal portion 74 exists at a position above the upper end of the combination of the first return ball prevention piece 63 and the first pedestal portion 64. However, the difference in height position between the lower end of the former and the lower end of the latter is less than the diameter of the game ball.

  The second return ball prevention unit 71 has a minimum distance L1 between the second return ball prevention piece 73 of the second return ball prevention unit 71 and the first return ball prevention piece 63 of the first return ball prevention unit 61. It is set to be 11 mm or more which is the diameter of the sphere. As a result, the game ball can flow downward from the position between the first return ball prevention unit 61 and the second return ball prevention unit 71. In order to make the flow of the game ball between the first return ball prevention unit 61 and the second return ball prevention unit 71 smooth, it is preferable that the shortest distance L1 is larger than 11 mm which is the diameter of the game ball, More preferably, it is 12 mm or more.

  The second return ball preventing unit 71 includes a tip of the second ball receiving portion 79 in the second return ball preventing piece 73 disposed at the initial position and a first in the first return ball preventing piece 63 disposed at the initial position. The distance L2 from the tip of the ball receiving portion 69 is set to be 11 mm or more which is the diameter of the game ball. Further, in order to make it difficult for the first ball receiving portion 69 in the first return ball preventing unit 61 to collide with the game balls from both the left and right at the same time, the distance L2 is 8 times the diameter of the game balls. It is preferably 88 mm or less, and more preferably 66 mm or less, which is six times the diameter of the game ball.

  In the configuration in which the first return ball prevention unit 61 and the second return ball prevention unit 71 are provided as described above, a plurality of nails 51 are provided around the first return ball prevention unit 61 and the second return ball prevention unit 71. Is provided. Specifically, a plurality of nails 51 are provided from the lower side of the first return ball prevention unit 61 to the lower side of the second return ball prevention unit 71 and from the lower side of the second return ball prevention unit 71. A plurality of nails 51 are provided to the right of the return ball prevention unit 71. When a game ball collides with a nail 51 provided to the right of the first return ball prevention unit 61 and to the left of the second return ball prevention unit 71 among the plurality of nails 51, the game ball May collide with the first ball receiving portion 69 of the first return ball preventing unit 61 from the right side, but the first ball receiving portion 69 prevents the game ball from flowing into the guide passage 37. Further, when a game ball collides with a nail 51 provided on the right side of the second return ball prevention unit 71, the game ball hits the second ball receiving portion 79 of the second return ball prevention unit 71 from the right side. Although a collision may occur, the movement to the first return ball prevention unit 61 side is prevented by the second ball receiving portion 79.

  On the other hand, the nail 51 is not provided on the movement path when the game ball led out from the guide passage 37 moves along the outer rail portion 36. Further, the nail 51 is not provided in a region above the imaginary line connecting the shaft portion of the first return ball prevention unit 61 and the shaft portion of the second return ball prevention unit 71. More specifically, a nail 51 is provided in a region above the imaginary line connecting the lower end of the first pedestal portion 64 of the first return ball prevention unit 61 and the lower end of the second pedestal portion 74 of the second return ball prevention unit 71. Is not provided. Thereby, it is possible to prevent the same game ball from repeatedly colliding with the nail 51 and the return ball prevention units 61 and 71 between the first return ball prevention unit 61 and the second return ball prevention unit 71. It becomes.

  Hereinafter, not only the first return ball prevention unit 61 but also the second return ball prevention unit 71 will be described. Prior to the description of the operation, a comparative example in the case where the second return ball prevention unit 71 is not provided will be described. FIG. 6 is a front view of the game board 501 showing an enlarged region where the first return ball prevention unit 502 is provided in the pachinko machine of the comparative example in which the second return ball prevention unit 71 is not provided.

  When the second return ball prevention unit 71 is not provided, the game ball B1 that has passed through the first return ball prevention unit 502 collides with the nail 503 and hits the ball receiving portion 504 of the first return ball prevention unit 502 from the right side. In the situation of collision, it is possible that the newly launched game ball B2 collides with the ball receiver 504 from the left. In this case, the game ball B1 colliding from the right flows down the game area 505 as it is, while the game ball B2 colliding from the left flows backward through the guide passage 506. The game ball B2 that has flowed back through the guide passage 506 collides with a game ball that has been subsequently fired, and the game ball including the game ball flows back through the guide passage 506. Such a backflow of game balls can repeatedly occur. The game ball that has flowed back through the guide passage 506 is collected by the foul ball collection unit 33 and discharged to the lower plate 26a, so that the player's holding ball does not lose, but while the game ball is flowing backward, The game ball is not supplied to the area 505.

  Next, the case of the pachinko machine 10 provided with not only the first return ball prevention unit 61 but also the second return ball prevention unit 71 will be described. FIGS. 7A, 7B, and 8 are front views of the game board 34 showing an enlarged region where the first return ball prevention unit 61 and the second return ball prevention unit 71 are provided.

  As shown in FIG. 7A, the game ball B1 that has passed through the second return ball prevention unit 71 collides with the nail 51 provided at a position close to the second return ball prevention unit 71, and the second Even if it collides with the second ball receiving portion 79 of the return ball prevention unit 71 from the right side, the game ball B2 subsequently fired is positioned around the first return ball prevention unit 61. In this case, an event in which the game ball collides from both the left and right sides with respect to the first ball receiving portion 69 in the first return ball prevention unit 61 does not occur, so that the game ball does not flow backward through the guide passage 37.

  In addition, as shown in FIG. 7B, when the game ball B <b> 1 that has passed through the second return ball prevention unit 71 collides with a nail 51 provided at a position far from the second return ball prevention unit 71. In the situation where the game ball B1 collides with the second ball receiving portion 79 of the second return ball preventing unit 71 from the right, the newly launched game ball B2 is left on the second ball receiving portion 79. Can collide from one side. In this case, the game ball B1 that has collided with the second ball receiving portion 79 of the second return ball preventing unit 71 from the right side flows down from the right side of the second ball receiving portion 79, and the second ball receiving portion. The game ball B <b> 2 that collided with 79 from the left flows down from between the first return ball prevention unit 61 and the second return ball prevention unit 71. Even in this event, the game ball does not collide from both the left and right sides in the first ball receiving portion 69 of the first return ball prevention unit 61, so that the game ball does not flow backward through the guide passage 37.

  Further, as shown in FIG. 8, the game ball B <b> 1 that has passed through the first return ball prevention unit 61 is to the right of the first return ball prevention unit 61 and to the left of the second return ball prevention unit 71. In the event of a collision with the nail 51 provided on the first ball, the game ball B1 may collide with the first ball receiving portion 69 of the first return ball prevention unit 61 from the right side. In this case, since the game ball B1 bounced off at a position close to the first return ball prevention unit 61 collides with the first ball receiving portion 69 of the first return ball prevention unit 61, the game ball B1 was fired next. The game ball B2 has not yet reached the position of the first return ball prevention unit 61. Accordingly, even in this case, there is no event that the game balls collide from both the left and right sides in the first ball receiving portion 69 of the first return ball prevention unit 61, so that the game balls do not flow backward through the guide passage 37. .

<Another form of return ball prevention structure>
Next, another embodiment of the return ball preventing structure will be described.

  (1) In another embodiment shown in FIG. 9, the first return ball prevention piece 63 and the second return ball prevention piece 73 are not provided on the separate base bodies 62 and 72 but are the same base body 82. These two return ball prevention pieces 63 and 73 are provided as the same return ball prevention unit 81. And the 1st base part 64 corresponding to the 1st return ball prevention piece 63 is integrally formed with respect to the said same base body 82, and the 2nd base part 74 corresponding to the 2nd return ball prevention piece 73 is formed. It is integrally formed. Accordingly, when the first return ball prevention piece 63 and the second return ball prevention piece 73 are arranged so that the relative position becomes a predetermined position, it is only necessary to perform the installation work of one return ball prevention unit 81. Therefore, the workability can be improved.

  (2) In another embodiment shown in FIG. 10, the second pedestal portion 91 of the second return ball prevention unit 71 is opposite to the guide passage 37 side with respect to the second base portion 78 of the second return ball prevention piece 73. It is opposed not only from the right side that is the side, but also from the left side that is the guide passage 37 side. More specifically, the second pedestal portion 91 is provided so as to surround the second base portion 78 around the axis of the second return ball preventing piece 73. However, the portion of the second pedestal portion 91 that faces the left surface of the second base portion 78 is in contact with the second base portion 78 at any rotational position of the second return ball prevention piece 73. In order to avoid this, the second base portion 78 is formed apart from the second base portion 78.

  In the said structure, the shortest distance between the 2nd base part 91 and the outer rail part 36 is longer than twice the diameter of a game ball. In this case, if a game ball that has been fired next reaches the position of the second return ball prevention piece 73 in a situation where the game ball is placed on the second pedestal portion 91, the game sphere is the second pedestal portion. It does not collide with the game ball on 91, but collides with the second ball receiving portion 79 from the left side. Accordingly, there is a possibility that the game ball led out from the guide passage 37 may directly collide with another game ball without colliding with the second return ball prevention piece 73 on the left side of the second return ball prevention piece 73. Reduced.

  Here, as shown in FIG. 11A, when the second pedestal portion 74 is configured to face the second base portion 78 only from the right side, the game ball B <b> 1 is temporarily placed on the second base portion 78. In the situation, when the next released game ball B2 reaches the position of the second return ball prevention piece 73, the game ball B2 does not collide with the game ball B1 placed on the second base portion 78. The second ball receiving portion 79 collides from the left side. In this case, the rotation of the second return ball preventing piece 73 toward the rotation limit position is prevented by the game ball B1 that is temporarily on the left surface of the second base portion 78. . Then, the game ball is moved to the right at the position of the second return ball prevention piece 73 even though the operation of launching the game ball is performed aiming to the right side of the second return ball prevention piece 73. Situations can occur where this is prevented.

  On the other hand, as shown in FIG. 11B, the second pedestal portion 91 is opposed to the left side surface of the second base portion 78, so that it collides with the second ball receiving portion 79 from the left side. Even if the game ball B <b> 1 is sufficiently absorbed by the collision, the game ball B <b> 1 is temporarily placed on the second pedestal portion 91 and not placed on the second base portion 78. In this case, when a new game ball B2 collides with the second ball receiving portion 79 from the left side in this situation, the second return ball prevention piece 73 rotates to the rotation side limit position as usual, and the second return ball The movement of the game ball B2 to the right of the prevention piece 73 is not blocked.

  (3) In another embodiment shown in FIG. 12, the lower end of the combination of the second return ball prevention piece 73 and the second pedestal portion 74 is lower than the upper end of the combination of the first return ball prevention piece 63 and the first pedestal portion 64. Exists in the position. Thereby, the possibility that the game ball led out from the guide passage 37 to the game area PT will bounce off the nail 51 and collide with the first ball receiving portion 69 of the first return ball prevention piece 63 from the right side is reduced. Even in this configuration, the distance between the tip of the second ball receiving portion 79 and the outer rail portion 36 is less than the diameter of the game ball in a situation where the second return ball preventing piece 73 is disposed at the initial position. The length dimension of the second ball receiving portion 79 is set so that In this case, the length dimension of the second ball receiving portion 79 is set to be larger than the length dimension of the first ball receiving portion 69. However, when the second return ball preventing piece 73 is arranged at a position closer to the first return ball preventing piece 63 than in the case of FIG. 12, the length dimension of the second ball receiving portion 79 is set to the first ball receiving portion. The lower end of the combination of the second return ball preventing piece 73 and the second pedestal portion 74 is lower than the upper end of the combination of the first return ball preventing piece 63 and the first pedestal portion 64 while being the same as the length dimension of the portion 69. The distance between the tip of the second ball receiving portion 79 and the outer rail portion 36 is less than the diameter of the game ball in the situation where the second return ball preventing piece 73 is located at the initial position. It becomes possible. Even in this different embodiment, the lower end of the combination of the second return ball prevention piece 73 and the second pedestal portion 74 is higher than the lower end of the combination of the first return ball prevention piece 63 and the first pedestal portion 64. Exists in position.

  (4) In another embodiment shown in FIG. 13, the first return ball prevention unit 61 is provided, but the second return ball prevention unit 71 is not provided. Instead, a ball escape opening 95 is formed at a position upstream of the ball outlet 37 b of the guide passage 37 in the inner rail portion 35 from the guide passage 37. The ball escape opening 95 is formed at a position biased toward the ball outlet 37b side of the guide passage 37 in the inner rail portion 35, and the distance from the ball outlet 37b is equal to or greater than the diameter of the game ball and the diameter of the game ball. Less than twice. However, the present invention is not limited to this, and the position of the upper end portion of the inner rail portion 35 is spaced downward with respect to the first return ball prevention unit 61, so that the ball outlet 37b of the guide passage 37 and the first return The ball escape opening 95 may be formed by setting the distance from the ball prevention unit 61 to be equal to or larger than the diameter of the game ball.

  The opening area of the ball escape opening 95 is an area through which one game ball can pass and two game balls cannot pass simultaneously. In addition, the ball escape opening 95 collides with the first ball receiving portion 69 from the right side on the falling path of the game ball that flows backward through the guide passage 37 or in the middle of the game ball flowing backward along the inner rail portion 35. Exists in position. As a result, in the situation where the game ball B1 is colliding with the first ball receiving portion 69 of the first return ball preventing unit 61 from the right side, the game ball B2 that has been launched next collides with the first ball receiving portion 69 from the left side. Even so, the game ball B2 is discharged from the ball escape opening 95 to the game area PT, and it is possible to prevent the game ball B2 from flowing backward in the guide passage 37 downward. The opening area of the ball escape opening 95 may be set to an area where two or more game balls can pass simultaneously.

  The ball escape opening 95 is provided with an inflow restricting plate 96 protruding toward the game area PT. The inflow restricting plate 96 protrudes downward from the upper end of the ball escape opening 95, and the opening direction of the ball escape opening 95 with respect to the game area PT is not vertically diagonally downward, but vertically downward or diagonally downward to the left. It is regulated. Accordingly, the game ball flowing back through the guide passage 37 can be discharged to the game area PT, and the game ball flowing down the game area PT collides with the nail 51 and enters the guide passage 37 through the ball escape opening 95. It is possible to prevent the entry.

  (5) The angle of the first ball receiving portion 69 of the first return ball preventing unit 61 and the angle of the second ball receiving portion 79 of the second return ball preventing unit 71 are not limited to the same configuration. It is good also as a structure from which both angles differ. For example, the first sphere receiving portion 69 may be inclined to the right to make the first sphere receiving portion 69 have an angle extending substantially horizontally, and the second sphere receiving portion 79 may be inclined to the left or right. Alternatively, it may be configured to stand in the vertical direction.

  (6) The length of the first ball receiving portion 69 of the first return ball preventing unit 61 is limited to the same configuration as the length of the second ball receiving portion 79 of the second return ball preventing unit 71. The length dimensions of the first ball receiving portion 69 and the second ball receiving portion 79 may be different. For example, the length dimension of the second sphere receiving portion 79 may be smaller than the length dimension of the first sphere receiving portion 69, and conversely, the length dimension of the second sphere receiving portion 79 is the first sphere receiving portion. It may be greater than the length dimension of 69.

  (7) The thickness of the first ball receiving portion 69 of the first return ball prevention unit 61 is limited to the same configuration as the thickness of the second ball receiving portion 79 of the second return ball prevention unit 71. Instead, the thickness dimensions of the first sphere receiving portion 69 and the second sphere receiving portion 79 may be different. For example, the thickness dimension of the second sphere receiving portion 79 may be smaller than the thickness dimension of the first sphere receiving portion 69, and conversely, the thickness dimension of the second sphere receiving portion 79 is the thickness of the first sphere receiving portion 69. It may be larger than the dimension.

  (8) The angle of the first base portion 68 of the first return ball prevention unit 61 and the angle of the second base portion 78 of the second return ball prevention unit 71 are not limited to the same configuration. It is good also as a structure from which these differ. Further, the left side surface (that is, the surface on the first return ball prevention unit 61 side) of the second base portion 78 of the second return ball prevention unit 71 is inclined downward toward the lower left at the initial position of the second return ball prevention piece 73. It is not limited to the structure which is carrying out, It is good also as a structure which the said left surface has stood up in the perpendicular direction, or is inclined down toward the lower right. In this case, it is possible to prevent an event that a game ball rides on the second base portion 78 of the second return ball prevention piece 73.

  (9) The first return ball preventing piece 63 may be moved from the initial position to the rotation-side limit position by driving with an electric actuator. In this case, a sensor for detecting a game ball is provided on the upstream side of the guide passage 37 from the first return ball prevention piece 63, and when the game ball is detected by the sensor, the first return ball is driven by the electric actuator. The ball prevention piece 63 may be configured to move to the rotation-side limit position. Even in this configuration, in the situation where the game ball collides with the first ball receiving portion 69 from the game area PT side, the movement of the first return ball prevention piece 63 toward the rotation side limit position is disturbed, In this situation, when the next game ball collides with the first ball receiving portion 69 from the guide passage 37 side, the collided game ball flows backward through the guide passage 37. Therefore, it is preferable that the second return ball preventing piece 73 is provided even in this configuration.

  (10) The second return ball preventing piece 73 may be moved from the initial position to the rotation-side limit position by driving with an electric actuator. In this case, a sensor for detecting the game ball is provided at a position closer to the first return ball prevention piece 63 than the second return ball prevention piece 73, and is driven by the electric actuator when the game ball is detected by the sensor. The second return ball prevention piece 73 may be moved to the rotation limit position.

  Various sensors such as various winning detection sensors 107a to 107e are connected to the input side of the MPU 103. The various winning detection sensors 107a to 107e are provided on a one-to-one basis with respect to winning-corresponding balls such as the general winning port 41, the special electric winning device 42, the first operating port 43, the second operating port 44, and the through gate 45. The detection sensor is included, and the MPU 103 makes a winning determination for each winning part. Further, in the MPU 103, various lotteries are executed on the basis of winning in the first operating port 43, and various lotteries are executed on the basis of winning in the second operating port 44.

  On the output side of the MPU 103, a power failure monitoring board 106, a payout control device 112, and a sound emission control device 114 are connected. For example, a prize ball command is output to the payout control device 112 based on a winning determination result to the winning corresponding winning part. Various commands such as a variation command, a type command, and an opening command are output to the sound emission control device 114.

  Further, on the output side of the MPU 103, a special electric drive unit 42b that opens and closes the open / close door 42a of the special electric prize winning device 42, and a general electric drive unit 44b that opens and closes the electric utility item 44a of the second operating port 44 The special figure unit 47 and the universal figure unit 48 are connected. Incidentally, the special figure unit 47 is provided with a special figure display unit 47 a and a special figure hold display unit 47 b, all of which are connected to the output side of the MPU 103. Similarly, the universal map unit 48 is provided with a universal map display unit 48 a and a universal map hold display unit 48 b, all of which are connected to the output side of the MPU 103. The main control board 102 is provided with various driver circuits, and the MPU 103 performs drive control of various drive units and various display units through the driver circuits.

  That is, in the opening / closing execution mode, the MPU 103 performs drive control of the special electricity drive unit 42b so that the special electricity prize winning device 42 is opened and closed. In addition, when the power utility item 44a is won, the MPU 103 executes drive control of the power generator 44b so that the power utility item 44a is opened and closed. In each game round, the display control of the special figure display unit 47 a is executed in the MPU 103. In addition, when the lottery result indicating whether or not to open the utility model 44a is clearly indicated, the MPU 103 executes display control of the normal diagram display unit 48a. In addition, when winning is awarded to the first working port 43 or the second working port 44, or when the variable display is started in the special figure display unit 47a, the display control of the special figure holding display unit 47b is executed in the MPU 103. When the winning to the through gate 45 is generated or when the variable display is started in the general map display unit 48a, the display control of the general map hold display unit 48b is executed in the MPU 103.

  The power failure monitoring board 106 relays between the main control board 102 and the power / fire control device 113, and monitors the DC stable voltage of 24 volts, which is the maximum voltage output from the power / fire control device 113. The payout control device 112 controls payout of prize balls and rental balls by the payout device 111 based on the prize ball command received from the main control device 101.

  The power / launch control device 113 is connected to, for example, a commercial power source (external power source) in a game hall or the like. Then, based on the external power supplied from the commercial power supply, necessary operating power is generated for each of the main control board 102, the payout control device 112, and the like, and the generated operating power is supplied. Incidentally, the power supply / launch control device 113 is provided with a power supply unit for power interruption such as a backup capacitor, and even when the power of the pachinko machine 10 is in the OFF state, the power supply unit for power interruption is connected to the main power supply unit for power interruption. Power for storing and holding is supplied to the RAM 105 of the control device 101.

  Further, the power source / launch control device 113 is responsible for the launch control of the game ball launch mechanism 38, and the game ball launch mechanism 38 continues to operate the launch operation device 39 and a predetermined launch condition is satisfied. In this case, it is driven at a cycle of once every 0.6 sec. In this case, in the game ball launching mechanism 38, when the game ball is continuously supplied onto the launch rail 38a by the ball feeding device 38b, the game ball is launched at a cycle of 0.6 sec. It will be.

  In addition, when the operation of the firing operation device 39 is continued and a situation where a predetermined launch condition is satisfied, the launch cycle of the game ball (that is, the drive cycle of the solenoid 38c) is limited to 0.6 sec. It may be shorter than 0.6 sec, such as 0.4 sec or 0.5 sec, and may be longer than 0.6 sec, such as 0.7 sec or 0.8 sec. Moreover, although it is slightly longer than 0.6 sec or slightly shorter than 0.6 sec, it may be substantially the same as 0.6 sec. However, in order to make the game ball firing cycle appropriate, the game ball firing cycle is preferably 0.6 sec or more. In this case, the number of game balls fired per minute is 100 or less.

  The sound emission control device 114 controls the display control device 115 while driving and controlling the display light emitting unit 23 and the speaker unit 24 provided on the front door frame 14 based on various commands received from the main control device 101. It is. The display control device 115 executes display control of the symbol display device 52 based on the command received from the sound emission control device 114.

<Electrical Configuration for Performing Various Lottery in MPU 103 of Main Controller 101>
Next, an electrical configuration for performing various lotteries in the MPU 103 of the main controller 101 will be described with reference to FIG.

  The MPU 103 uses lots of counter information during the game to perform jackpot occurrence lottery, display setting of the special symbol display unit 47a, setting of symbol display of the symbol display device 52, setting of display of the general symbol display unit 48a, and the like. Specifically, as shown in FIG. 15, the winning random number counter C1 used for the winning lottery, the big hit type counter C2 used for determining the big hit type, and the symbol display device 52 are fluctuating and changing. When determining the reach random number counter C3 used for the reach generation lottery, the random number initial value counter CINI used for setting the initial value of the hit random number counter C1, and the display duration in the special figure display unit 47a and the symbol display device 52 The variation type counter CS to be used is used. Further, the utility power release counter C4 used for the lottery to determine whether or not the utility power item 44a of the second operating port 44 is set to the utility power release state is used. The counters C1 to C3, CINI, CS, and C4 are provided in various counter areas 105a of the RAM 105.

  Each of the counters C1 to C3, CINI, CS, and C4 is a loop counter that adds 1 to the previous value every time it is updated and returns to 0 after reaching the maximum value. Each counter is updated at short intervals. Information corresponding to the winning random number counter C1, the big hitting type counter C2 and the reach random number counter C3 is stored in the holding storage area 105b provided in the RAM 105 when a winning to the first operating port 43 or the second operating port 44 occurs. Stored.

  The holding storage area 105b includes a holding area RE and an execution area AE. The holding area RE includes a first holding area RE1, a second holding area RE2, a third holding area RE3, and a fourth holding area RE4. In the winning history to the first operating port 43 or the second operating port 44, In addition, combinations of numerical information of the hit random number counter C1, the big hit type counter C2, and the reach random number counter C3 are stored as hold information in any of the hold areas RE1 to RE4. In this case, in the first reservation area RE1 to the fourth reservation area RE4, when the winning to the first operation port 43 or the second operation port 44 is continuously generated a plurality of times, the first reservation area RE1 → second Each numerical information is stored in time series in the order of the reserved area RE2 → the third reserved area RE3 → the fourth reserved area RE4. By providing the four holding areas RE1 to RE4 as described above, up to four game balls winning histories to the first operating port 43 or the second operating port 44 are stored and stored. . Note that the number that can be reserved and stored is not limited to four, but may be any other number such as two, three, or five or more.

  The execution area AE is an area for moving each numerical information stored in the first holding area RE1 of the holding area RE when starting the variable display of the special figure display unit 47a, and starting one game round At this time, determination of success or failure is performed based on various numerical information stored in the execution area AE.

  Each of the counters will be described in detail.

  First, the general electric utility release counter C4 will be described. For example, the utility power release counter C4 is incremented by 1 in the range of 0 to 250, and returns to 0 after reaching the maximum value. The general electric utility release counter C4 is periodically updated and stored in the general electric power holding area 105c of the RAM 105 at a timing when a game ball wins the through gate 45. Then, at a predetermined timing, a lottery is performed as to whether or not to control the universal utility 44a to the open state based on the stored value of the universal utility release counter C4.

  In the pachinko machine 10, a plurality of types of support modes are set so that the modes of support by the general electric utility 44 a are different from each other. Specifically, in the support mode, when compared with a situation in which a game ball is continuously being fired in a similar manner with respect to the game area, the utility object 44a of the second operation port 44 is per unit time. The high frequency support mode and the low frequency support mode are set so that the frequency of the open state is relatively high.

  In the high frequency support mode and the low frequency support mode, the probability of winning the electric power open state in the electric power open lottery using the electric power utility opening counter C4 is the same (for example, both 4/5). In the high frequency support mode, the number of times that the power utility 44a is opened when the public power open state is elected is set more than in the low frequency support mode, and the opening time of one time is set longer. Has been. In this case, in the high frequency support mode, when the open state of the public power supply is selected and the open state of the general utility 44a occurs a plurality of times, from the end of one open state to the start of the next open state. The closing time is set shorter than one opening time. Furthermore, in the high frequency support mode, the minimum reserved time (i.e., the normal map) is required for the next open train lottery after the first open train lottery than the low frequency support mode. The display continuation time for the display unit 48a is set short.

  As described above, in the high frequency support mode, the probability of winning a prize to the second operation port 44 is higher than in the low frequency support mode. In other words, in the low frequency support mode, there is a higher probability of winning the first operation port 43 than in the second operation port 44, but in the high frequency support mode, the second operation is performed more than in the first operation port 43. The probability of winning a prize in the mouth 44 increases. When a winning in the second operation port 44 occurs, a predetermined number of game balls are paid out. Therefore, in the high-frequency support mode, the player plays a game while not reducing the number of possessed balls. It can be carried out.

  Note that the configuration for increasing the frequency at which the high frequency support mode is set to the normal power open state per unit time as compared to the low frequency support mode is not limited to the above, for example, in the general power open lottery It is good also as a structure which raises the probability that it will be elected in an open state of a public train. In addition, a secured time (for example, executed by the general map display unit 48a based on a winning to the through gate 45) is secured after the next public train opening lottery is performed. In a configuration in which a plurality of types of variable display time) are prepared, the high frequency support mode is set so that a short securing time is easily selected or the average secure time is shorter than the low frequency support mode. Also good. Furthermore, increase the number of times of opening, lengthen the opening time, and shorten the reserved time that will be secured when the next public train opening lottery is performed after the first public train opening lottery is performed, the reserved time concerned The advantage of the high-frequency support mode over the low-frequency support mode may be increased by applying any one condition or any combination of conditions among shortening the average time and increasing the winning probability.

  Next, the winning random number counter C1 will be described. For example, the winning random number counter C1 is incremented one by one within a range of 0 to 599, and after reaching the maximum value, returns to 0. In particular, when the winning random number counter C1 makes one round, the value of the initial random number counter CINI at that time is read as the initial value of the winning random number counter C1. The random number initial value counter CINI is a loop counter similar to the winning random number counter C1 (value = 0 to 599). The winning random number counter C <b> 1 is periodically updated and stored in the storage area 105 b of the RAM 105 at the timing when the game ball wins the first operation port 43 or the second operation port 44.

  The random number value for winning the big hit is stored in the ROM 104 as a success / failure table. As the success / failure table, a success / failure table for the low probability mode and a success / failure table for the high probability mode are set. That is, in the pachinko machine 10, the low probability mode and the high probability mode are set as the lottery modes in the success / failure lottery means.

  In the gaming state in which the winning / failing table for the low probability mode is referred to at the time of the lottery, the number of random numbers that win the jackpot is two. On the other hand, in the gaming state in which the winning / failing table for the high probability mode is referred to at the time of the lottery, the number of random numbers that will win the jackpot is 20. If the winning probability in the high probability mode is higher than that in the low probability mode, the number of random numbers to be won is arbitrary.

  The jackpot type counter C2 is configured so that 1 is added in order within a range of 0 to 29, and after reaching the maximum value, it returns to 0. The big hit type counter C2 is periodically updated and stored in the holding storage area 105b at the timing when the game ball wins the first operation port 43 or the second operation port 44.

  In the pachinko machine 10, a plurality of jackpot results are set. The plurality of jackpot results are as follows: (1) the mode of opening / closing control of the special prize winning device 42 in the opening / closing execution mode, (2) the lottery mode in the winning lottery means after the opening / closing execution mode ends, and (3) the second after the opening / closing execution mode ends. A plurality of jackpot results are set by making a difference in the three conditions of the support mode in the general electric utility 44a of the two operation ports 44.

  As an aspect of the opening / closing control of the special electricity prize winning device 42 in the opening / closing execution mode, the occurrence frequency of winning in the special electricity prize winning device 42 from the start to the end of the opening / closing execution mode is relatively high. A frequency winning mode and a low frequency winning mode are set. Specifically, in any of the high-frequency winning mode and the low-frequency winning mode, the game is executed with a predetermined number of round games as an upper limit.

  Here, the round game is continued until a predetermined upper limit duration elapses or a predetermined upper limit number of game balls wins the special electric prize winning device 42. It is a game to play. In addition, the number of round games in the opening / closing execution mode triggered by the jackpot result is the same for a fixed number of rounds regardless of the type of jackpot result triggered by the transition. Specifically, the upper limit number of round games is set to 15 rounds regardless of which jackpot result is obtained.

  Moreover, in this pachinko machine 10, a plurality of types of opening modes of the special electricity winning device 42 are set with different opening durations from when the special electricity winning device 42 is opened until it is closed. Specifically, a long-time mode set to 29 sec, which is a long open duration, and a short-time mode set to 0.06 sec, which is a short duration shorter than the above long time, are set. Has been.

  In the present pachinko machine 10, in a situation where the launch operation device 39 is operated by the player, the game ball launching mechanism 38 is driven and controlled so that one game ball is launched toward the game area every 0.6 sec. The In the round game, the upper limit number of end conditions is set to nine. Then, in the long time mode among the above open modes, the open duration time is set longer than the product of the game ball firing period and one round game. On the other hand, in the short-time mode, an opening continuation time is set that is shorter than the product of the game ball launch cycle and one round game, more specifically, shorter than the game ball launch cycle. Therefore, when the opening is performed once in the long-time mode, it is expected that the special electric prize winning device 42 will receive the maximum number of winnings in one round game. If the number of times is released, it is expected that no special prize winning device 42 will be awarded or even if a prize will be generated.

  In the high-frequency winning mode, the special prize winning device 42 is opened once in each round game in a long-time manner. On the other hand, in the low-frequency winning mode, the special prize winning device 42 is opened once in a round mode in each round game.

  The number of opening / closing of the special prize winning device 42 in the high frequency winning mode and the low frequency winning mode, the number of round games, the opening duration for one open and the upper limit number in one round game are those in the high frequency winning mode. As long as the occurrence frequency of the prize to the special electricity prize winning device 42 is higher than the low frequency prize winning mode between the start and end of the opening / closing execution mode, the value is not limited to the above value. It is.

  The game result distribution destination for the big hit type counter C2 is stored in the ROM 104 as a distribution table. And as such a distribution destination, a low probability big hit result, a low winning high probability big hit result, and the most advantageous big hit result are set.

  The low probability big hit result is a big hit result in which the open / close execution mode becomes the high-frequency winning mode, and after the open / close execution mode ends, the win / fail lottery mode becomes the low probability mode and the support mode becomes the high frequency support mode. However, the high-frequency support mode shifts to the low-frequency support mode when the number of games reaches the end reference number (specifically, 100 times) after the shift.

  The low-winning high-probability jackpot result is a jackpot result in which the opening / closing execution mode becomes the low-frequency winning mode, and after the opening / closing execution mode ends, the success / failure lottery mode becomes the high probability mode and the support mode becomes the high-frequency support mode. is there. These high-probability mode and high-frequency support mode are continued until the lottery result in the success / failure lottery becomes a big hit state win and shifts to the big win state by that.

  The most advantageous jackpot result is a jackpot result in which the opening / closing execution mode becomes the high-frequency winning mode, and after the opening / closing execution mode ends, the winning / raising lottery mode becomes the high probability mode and the support mode becomes the high-frequency support mode. These high-probability mode and high-frequency support mode are continued until the lottery result in the success / failure lottery becomes a big hit state win and shifts to the big win state by that.

  Note that the normal game state in relation to each of the above-described game states refers to a state in which the success / failure lottery mode is the low probability mode and the support mode is the low frequency support mode, not the open / close execution mode.

  In the distribution table, among the values of the big hit type counter C2 of “0 to 29”, “0 to 9” corresponds to the low probability big hit result, and “10 to 14” corresponds to the low winning high probability big hit result. “15 to 29” corresponds to the most favorable jackpot result.

  Next, the reach random number counter C3 will be described. For example, the reach random number counter C3 is incremented one by one within a range of 0 to 238, for example, and reaches a maximum value and then returns to 0. Here, in this pachinko machine 10, an expected effect is set as a kind of display effect in the symbol display device 52. The expected effect includes a symbol display device 52 that can perform variable display of symbols, and in a gaming machine in which a final stop result is an assignment corresponding result in a game round that results in a predetermined jackpot result, the symbol display device 52 This is a display state for making the player think that it is a variable display state that is likely to be the above-mentioned giving correspondence result at the stage before the stop result is derived and displayed after the symbol variable display is started. In addition, about the provision corresponding | compatible result, the combination of the symbol to which the same number was attached | subjected on one of the effective lines is stopped and displayed.

  In the expected effect, two types of reach display and a notice display for expecting the occurrence of reach display and the generation of the result of giving correspondence at a stage before the reach display occurs are set.

  In the reach display, a combination of reach symbols is displayed by stopping and displaying symbols for some of the symbol sequences displayed on the display surface of the symbol display device 52, and the remaining symbol sequences are displayed in that state. Includes a display state in which symbols are displayed in a variable manner. In addition, in the state where the combination of reach symbols is displayed as described above, the variation of the symbols is displayed in the remaining symbol rows, and a predetermined character or the like is displayed as a moving image on the background screen, and the reach effect is performed. In addition, there are those that perform a reach effect by displaying a predetermined character or the like as a moving image on substantially the entire display surface after reducing or not displaying a combination of reach symbols.

  In the notice display, in a situation where the symbols are variably displayed in all the symbol sequences after the symbol variation display is started on the display surface of the symbol display device 52, or in some symbol sequences, a plurality of symbols are displayed. In a situation where the symbols are displayed in a variable manner in the symbol row, a mode in which a character is displayed separately from the symbols on the symbol row is included. Moreover, what makes a background screen the predetermined aspect different from the previous aspect, and what makes the symbol on a symbol row the predetermined aspect different from the previous aspect are also included. Such a notice display can occur in any game times when reach display is performed and when reach display is not performed, but the case where reach display is performed is higher than the case where reach display is not performed. It is set to occur with probability.

  The reach display is executed regardless of the value of the reach random number counter C3 in the game times in which the combination of the same symbols is finally stopped. In addition, the game times corresponding to the jackpot result in which the same symbol combination is not stopped and displayed are not executed regardless of the value of the reach random number counter C3. Further, in the game times corresponding to the losing result, it is executed when the reach random number counter C3 acquired at a predetermined timing with reference to the reach table stored in the ROM 104 corresponds to the occurrence of reach display.

  On the other hand, the determination as to whether or not to perform the notice display is performed not by the main control device 101 but by the sound emission control device 114. In this case, the sound emission control device 114 is more likely to generate a notice display in the game times corresponding to any of the jackpot results than in the game times corresponding to the result of losing, and a notice display having a low appearance rate. A lottery process for displaying a notice is executed so as to satisfy at least one of the conditions of being easily generated. Incidentally, the lottery result is reflected when the game display effect is executed on the symbol display device 52.

  Next, the variation type counter CS will be described. The variation type counter CS is, for example, incremented by 1 within a range of 0 to 198, and returns to 0 after reaching the maximum value. The variation type counter CS is used when the MPU 103 determines the display continuation time in the special symbol display unit 47a and the symbol display continuation time in the symbol display device 52. The variation type counter CS is updated once every time a normal process to be described later is executed once, and is repeatedly updated even within the remaining time in the normal process. Then, the buffer value of the variation type counter CS is acquired when the variation pattern is determined at the start of variation display in the special symbol display unit 47a and at the time of symbol variation start by the symbol display device 52.

<About the processing configuration of the main controller 101>
Next, each process performed in order to advance a game in MPU103 of the main control apparatus 101 is demonstrated. The processing of the MPU 103 is roughly classified into main processing that is started when the power is turned on and timer interrupt processing that is started periodically (in this embodiment, at a cycle of 4 msec).

<Main processing>
First, the main process will be described with reference to the flowchart of FIG.

  In step S101, power-on wait processing is executed. In the power-on wait process, for example, the process waits without progressing to the next process until a predetermined time for wait (specifically 1 sec) elapses after the main process is activated. The operation start and initial setting of the symbol display device 52 are completed during the execution period of the power-on wait process. In the subsequent step S102, access to the RAM 105 is permitted, and in step S103, the internal function register of the MPU 103 is set.

  Thereafter, in step S104, it is determined whether or not the RAM erasure switch provided in the power / fire control device 113 is manually operated. In subsequent step S105, whether or not the power failure flag of the RAM 105 is set to “1” is determined. Determine whether. In step S106, a checksum calculation process for calculating a checksum is executed. In subsequent step S107, whether or not the checksum matches the checksum stored when the power is turned off, that is, the validity of the stored data is checked. judge.

  In the pachinko machine 10, for example, when RAM data is initialized when the power is turned on, such as when a game hall starts business, the power is turned on while the RAM erase switch is pressed. Therefore, if the RAM erase switch is pressed, the process proceeds to step S108. Similarly, when the information on occurrence of power shutdown is not set, or when an abnormality of data stored and held is confirmed by the checksum, the process proceeds to step S108. In step S108, the RAM 105 is cleared. Thereafter, the process proceeds to step S109.

  On the other hand, if the RAM erase switch has not been pressed, step S109 is executed without executing step S108 on condition that the power failure flag is set to “1” and the checksum is normal. Proceed to In step S109, a power-on setting process is executed. In the power-on setting process, a predetermined area of the RAM 105 such as initialization of a power failure flag is set to an initial value, and a command corresponding to the current gaming state is transmitted to the sound emission control device 114 in order to recognize the current gaming state. To do.

  Then, it progresses to the residual process of step S110-step S113. That is, the MPU 103 is configured to periodically execute the timer interrupt process, but a remaining time is generated between one timer interrupt process and the next timer interrupt process. The remaining time varies depending on the processing completion time of each timer interrupt process, but the remaining processes in steps S110 to S113 are repeatedly executed using such irregular time. In this regard, it can be said that the remaining processes in steps S110 to S113 are non-periodic processes that are performed irregularly.

  In the remaining process, first, in step S110, an interrupt prohibition setting is performed in order to prohibit the generation of the timer interrupt process. In the subsequent step S111, a random number initial value update process for updating the random number initial value counter CINI is executed, and a change counter update process for updating the change type counter CS is executed in step S112. In these update processes, the current numerical information is read from the corresponding counter in the RAM 105, the process of adding 1 to the read numerical information is executed, and then the process of overwriting the read-out counter is executed. In this case, each counter value is cleared to “0” when it reaches the maximum value. Thereafter, in step S113, an interrupt permission setting for switching from a state in which the generation of the timer interrupt process is prohibited to a state in which the timer interrupt process is permitted is performed. If the process of step S113 is performed, it will return to step S110 and will repeat the process of step S110-step S113.

<Timer interrupt processing>
Next, timer interrupt processing will be described with reference to the flowchart of FIG. The timer interrupt process is executed periodically (for example, at a cycle of 4 msec).

  First, in step S201, a power failure information storage process is executed. In the power outage information storage process, it is monitored whether or not a power outage signal corresponding to the occurrence of power interruption is received from the power outage monitoring board 106, and when the occurrence of a power outage is specified, the process during power outage is executed.

  In subsequent step S202, a lottery random number update process is executed. In the lottery random number update process, the big hit random number counter C1, the big hit type counter C2, the reach random number counter C3, and the universal utility release counter C4 are updated. Specifically, the current numerical information is sequentially read from the jackpot random number counter C1, the jackpot type counter C2, the reach random number counter C3, and the universal utility release counter C4, and a process of adding 1 to each of the read numerical information is executed. Later, a process of overwriting the reading source counter is executed. In this case, each counter value is cleared to “0” when it reaches the maximum value.

  Thereafter, in step S203, the random number initial value update process is executed in the same manner as in step S111, and in step S204, the variation counter update process is executed in the same manner as in step S112.

  In subsequent step S205, a fraud detection process for monitoring whether or not a predetermined event set as a fraud monitoring target has occurred is executed. In the fraud detection process, the occurrence of a plurality of types of events is monitored, and by confirming that a predetermined event has occurred, “1” is set to the game stop flag provided in the RAM 105.

  In the subsequent step S206, it is determined whether or not the progress of the game is stopped by determining whether or not “1” is set in the game stop flag. If a negative determination is made in step S206, the processing after step S207 is executed.

  In step S207, port output processing is executed. In the port output process, when output information has been set in the previous timer interrupt process, a process for performing output corresponding to the output information to the various drive units 42b and 44b is executed. For example, when the information for switching the special electric prize winning device 42 to the open state is set, the output of the drive signal to the special electric drive unit 42b is started, and when the information to be switched to the closed state is set. Stops the output of the drive signal. In addition, when the information for switching the power utility 44a of the second working port 44 to the open state is set, the output of the drive signal to the power drive unit 44b should be started and switched to the closed state. When the information is set, the output of the drive signal is stopped.

  In a succeeding step S208, a reading process is executed. In the reading process, signals other than the power failure signal and the winning signal are read, and the read information is stored for use in future processing.

  In subsequent step S209, a winning detection process is executed. In the winning detection process, signals received from the winning detection sensors 107a to 107e are read, and the general winning port 41, the special electric winning device 42, the first operating port 43, the second operating port 44, and the through gate 45 are read. A process for specifying the presence or absence of winning is executed.

  In the subsequent step S210, timer update processing for updating the numerical information of a plurality of types of timer counters provided in the RAM 105 collectively is executed. In this case, the timer counter that is updated by subtracting the stored numerical information is handled in an integrated manner. However, both the updating of the subtracting timer counter and the updating of the adding timer counter are performed collectively. It is good also as a structure.

  In the subsequent step S211, a launch control process for controlling the launch of the game ball is executed. In the situation where the launch operation to the launch operation device 39 is continued, as described above, one game ball is launched at 0.6 sec which is a predetermined launch cycle. In this case, the launch strength of the game ball is determined by the amount of rotation operation of the operation handle 39b in the launch operation device 39 as already described. For example, when the rotation operation amount of the operation handle 39b is adjusted such that the game ball launch strength in the game ball launch mechanism 38 is the first launch strength, the game ball is normally supplied to the game area PT. As a condition, the released game ball flows down from the space between the first return ball prevention unit 61 and the second return ball prevention unit 71 downward in the game area PT. In other words, the game ball passes through the first ball receiving portion 69 of the first return ball prevention unit 61, while the game area faces downward without reaching the second ball reception portion 79 of the second return ball prevention unit 71. Flow down PT. When the operation handle 39b is operated so that the firing intensity becomes less than the first firing intensity, the launched game ball is guided without passing through the first ball receiving portion 69 of the first return ball prevention unit 61. The passage 37 flows backward.

  On the other hand, when the rotation operation amount of the operation handle 39b is adjusted so that the game ball launch strength in the game ball launch mechanism 38 becomes the second launch strength, the game ball is normally supplied to the game area PT. As a condition, the released game ball passes through not only the first ball receiving portion 69 of the first return ball preventing unit 61 but also the second ball receiving portion 79 of the second return ball preventing unit 71, and the second return ball The game area PT flows down from a position on the right side of the ball prevention unit 71 downward. Within a range that is greater than or equal to the first launch intensity and less than the second launch intensity, the game ball flows downward from the side closer to the second return ball prevention unit 71 as the amount of rotation of the operation handle 39b is increased. . In addition, at the second firing strength or higher, the game ball flows downward from a position farther to the right than the second return ball prevention unit 71 as the rotation amount of the operation handle 39b is increased.

  In a situation where the player is not in the opening / closing execution mode, the player basically operates the launch operation device 39 with the aim of entering the game ball into the first operation port 43 or the second operation port 44. Further, in the situation of the opening / closing execution mode, the launch operation device 39 is basically operated with the aim of the game ball entering the special electricity prize winning device 42. In this case, depending on the situation of the nail 51 in the game area PT, the firing operation device 39 is operated so that the game ball flows down from between the first return ball prevention unit 61 and the second return ball prevention unit 71. In some cases, it is possible to increase the probability of entering the entrance part where the player is aiming to enter the game, and when the second return ball prevention unit 71 is released, the game ball will flow downward from the right side. In some cases, it is possible to increase the probability of entering the entrance portion where the operation device 39 is operated to enter the entrance. Therefore, the game ball plays a game while appropriately adjusting the operation mode of the firing operation device 39.

  In the subsequent step S212, as input status monitoring processing, disconnection confirmation of the winning detection sensors 107a to 107e and opening confirmation of the gaming machine main body 12 and the front door frame 14 are performed based on the information read in the reading processing in step S208. Do.

  In the subsequent step S213, a special figure special electric control process for performing execution control of the game times and execution control of the opening / closing execution mode is executed. In the special figure special electric control process, when a winning to the first operation port 43 or the second operation port 44 occurs in a situation where the number of the hold information stored in the hold storage area 105b is less than the upper limit number, A process of storing the numerical information of the jackpot random number counter C1, the jackpot type counter C2 and the reach random number counter C3 at the time as the hold information in the hold storage area 105b in time series is executed. Also, in the special figure special electric control process, whether or not the hold information corresponds to the big win is determined on the condition that the hold information is not stored during the game rotation and the opening / closing execution mode and is stored. If it corresponds to the process and the jackpot winning, a distribution determination process for determining which jackpot result the hold information corresponds to is executed. In addition, in the special figure special power control process, not only the success / failure determination process and the distribution determination process, but if the hold information does not correspond to the big win, whether the hold information corresponds to the occurrence of reach. A reach determination process is performed, and a process of selecting a game time duration using the numerical information of the variation type counter CS at that time is executed. Then, the variation command including the duration information corresponding to the result of each process and the type command including the game result information are transmitted to the sound emission control device 114, and the pattern in the special figure display unit 47a is displayed. Start the variable display. As a result, one game round is started, and an effect for game round is started on the special figure display unit 47a and the symbol display device 52.

  Also, in the special figure special electric control process, during the execution of one game round, it is determined whether or not it is the end timing of the game round. If it is the end timing, the display corresponding to the game result is performed. Then, the process of ending the game round is executed. In this case, a final stop command indicating that the game round should be ended is transmitted to the sound emission control device 114. Further, in the special figure special electric control process, when the result of the game times is a result corresponding to the transition to the opening / closing execution mode, a process for starting the opening / closing execution mode is executed. At the start, an opening command indicating that the opening / closing execution mode is started is transmitted to the sound emission control device 114. In the special figure special electric control process, a process for starting each round game and a process for ending each round game are executed. In each of these processes, an open command indicating that the round game is started is transmitted to the sound emission control device 114, and a close command indicating that the round game is ended is transmitted to the sound light control device 114. Further, in the special figure special electric control process, when the opening / closing execution mode is ended, an ending command indicating that is sent to the sound emission control device 114, and the success / failure lottery mode and the support mode after the opening / closing execution mode are set. Execute the process.

  After executing the special figure special electric control process of step S213 in the timer interruption process, the normal figure electric power control process is executed in step S214. In the general-purpose power control process, when a winning to the through gate 45 is generated, a process for acquiring the general-information hold information is executed and the general-purpose hold information is stored. In addition, a release determination is performed on the hold information, and a process for performing an effect for a normal diagram is executed using the release determination as a trigger. Further, based on the result of the opening determination, a process for opening and closing the utility member 44a of the second working port 44 is executed.

  In the subsequent step S215, setting of output information for reflecting the increase / decrease number of the hold information related to the special figure display unit 47a in the special figure hold display unit 47b based on the processing results of the immediately preceding steps S213 and S214 is performed. The output information for reflecting the increase / decrease number of the hold information related to the general map display section 48a to the general map display section 48b is set. In step S215, output information for updating the display content of the special figure display unit 47a is set based on the processing results of the immediately preceding steps S213 and S214, and the display content of the general map display unit 48a is set. Set the output information to be updated.

  In the following step S216, the contents of the command and signal received from the payout control device 112 are confirmed, and a payout state receiving process for performing a process corresponding to the confirmation result is executed. In step S217, a payout output process for setting a prize ball command as an output target is executed. In the subsequent step S218, an external information setting process for controlling the start and end of the output of the external signal according to the processing results of the various processes executed in the current timer interrupt process is executed. Thereafter, the timer interrupt process is terminated.

  According to the present embodiment described in detail above, the game board 34 is not only provided with the first return ball prevention piece 63 for preventing the inflow of game balls from the game area PT to the guide passage 37 but also from the guide passage 37. A second return ball prevention piece 73 is provided for preventing the game ball led to the region PT from colliding with the first ball receiving portion 69 of the first return ball prevention piece 63. This makes it difficult for the first ball receiving portion 69 of the first return ball preventing piece 63 to cause an event that the game ball collides also from the guide path 37 side in a situation where the game ball collides from the game region PT side. It becomes possible. Therefore, it is possible to reduce the possibility that the game ball will flow backward through the guide passage 37 in the situation where the game ball is being launched with the firing strength passing through the first return ball prevention piece 63.

  The second return ball prevention piece 73 is provided such that the shortest distance between the second return ball prevention piece 73 and the first return ball prevention piece 63 is equal to or greater than the diameter of the game ball. As a result, even if the game ball collides from the left side in a situation where the game ball collides with the second ball receiving portion 79 of the second return ball prevention piece 73 from the right side, Rather than staying between the ball prevention piece 63 and the second return ball prevention piece 73, it flows down from between the first return ball prevention piece 63 and the second return ball prevention piece 73. .

  It should be noted that the structure for preventing the return ball as described above is performed not from the pachinko machine 10 of the type in which the game ball is derived from the upper left of the game area PT but from the upper right of the game area PT. The present invention may be applied to a type of pachinko machine. In this case, the second return ball prevention piece 73 is arranged on the left side with respect to the first return ball prevention piece 63.

  The structure for preventing the return ball as described above may be applied to other types of pachinko machines different from the pachinko machine 10. For example, a pachinko machine that unlocks a predetermined number of times when a game ball enters a specific area of a special device, a pachinko machine that generates a right when a game ball enters a specific area of a special device, and other roles The structure for preventing the return ball as described above can also be applied to a gaming machine such as a pachinko machine, an arrangement ball machine, or a sparrow ball provided with an object.

<Example>
Hereinafter, in the situation where a game ball is being fired with a distance between the first return ball prevention piece 63 and the second return ball prevention piece 73 and with a firing strength passing through the first return ball prevention piece 63, the guide path 37 will be described in detail as an example of the relationship between the frequency at which the game ball flows backward. However, the present invention is not limited to the following examples.

  FIG. 18 is a front view of the inner frame 13 in the pachinko machine 10 used in the experiment. The configuration of the inner frame 13 is the same as the configuration described with reference to FIG. The longest lateral distance X in the gaming area PT formed on the gaming board 34 is 433 mm, and the longest longitudinal distance Y in the gaming area PT is 583 mm. The distance from the tip E of the first ball receiving portion 69 of the 1 return ball preventing piece 63 is 748 mm. When the game ball launching mechanism 38 operates, the game ball held at the launch point S passes through the guide passage 37 and presses the first ball receiving portion 69 of the first return ball preventing piece 63 to prevent the first ball receiving. The piece 63 is supplied to the game area PT by turning to the turning limit position. The game ball launching mechanism 38 performs a game ball launching operation at a predetermined cycle when the operation of the launch operation device 39 is continued and a predetermined launch condition is established.

  FIG. 19 is an enlarged front view of the game board 34 showing an area where the first return ball prevention piece 63 and the second return ball prevention piece 73 are provided in the pachinko machine 10 used in the experiment. The configuration of the game board 34 is the same as the configuration described with reference to FIGS. 3 to 5 including the first return ball prevention piece 63 and the second return ball prevention piece 73. In this case, the first return ball prevention piece 63 and the second return ball prevention piece 73 are individually provided as the first return ball prevention unit 61 and the second return ball prevention unit 71, respectively, and these first return ball prevention pieces 71 are provided. As the unit 61 and the second return ball prevention unit 71, return ball prevention units having the same configuration, size and shape are used. In this case, the length dimension of the ball receiving portions 69 and 79 is 16 mm, the thickness dimension of the ball receiving portions 69 and 79 is 1 mm, the length dimension of the base portions 68 and 78 is 13 mm, and the base portion 68, The thickness dimension of 78 is 6 mm, and the width dimension of the base parts 68 and 78 and the ball receiving parts 69 and 79 is 12 mm. Moreover, the base parts 64 and 74 are formed so that the base parts 68 and 78 may be followed, and the thickness dimension is 1 mm. The return ball preventing pieces 63 and 73 are made of polyethylene, and the base bodies 62 and 72 are made of polycarbonate. The return ball preventing pieces 63 and 73 and the base bodies 62 and 72 have a smaller rebound hardness than the nails 51a to 51g.

  In addition, a plurality of nails 51 a to 51 g are provided as nails 51 around the first return ball prevention piece 63 and the second return ball prevention piece 73. Among the plurality of nails 51a to 51g, the nails 51a to 51c are the first ball receiving portions of the first return ball preventing piece 63 from the game area PT side when the game balls led out from the guide passage 37 to the game area PT bounce off. An event that collides with 69 may occur. On the other hand, the nails 51d to 51g cause an event that the game ball led out from the guide passage 37 to the game area PT rebounds and collides with the second ball receiving portion 79 of the second return ball prevention piece 73 from the game area PT side. In other words, an event of colliding with the first ball receiving portion 69 of the first return ball preventing piece 63 is not generated.

  In this experiment, the shortest distance L1 between the combination of the first return ball prevention piece 63 and the first pedestal portion 64 and the combination of the second return ball prevention piece 73 and the second pedestal portion 74 is disposed at the initial position. The distance L2 between the tips between the tip of the first ball receiving portion 69 in the return ball preventing piece 63 and the tip of the second ball receiving portion 79 in the second return ball preventing piece 73 arranged at the initial position, the first sphere Of the nails 51a to 51c that can cause a collision of a game ball from the game area PT side to the receiving portion 69, the nail 51a and the first ball receiving portion 69 that are located closest to the first ball receiving portion 69 The shortest nail distance L3 between the tip and the position farthest from the first ball receiving portion 69 among the nails 51a to 51c that can cause the game ball to collide with the first ball receiving portion 69 from the game area PT side. Between the nail 51b existing on the tip of the first ball receiving portion 69 Each length nail distance L4 was prepared game board 34 which is a combination of experimental conditions A1~G4 as shown in FIG. 20. In this case, when the distance L2 between the tips is changed, the distance between the tip of the second ball receiving portion 79 and the outer rail portion 36 is kept constant (specifically, 4 mm), and the first return ball prevention unit 61 with respect to the first return ball prevention unit 61 is changed. 2. This was done by changing the relative position of the return ball prevention unit 71.

  Note that, in any experimental condition, a phantom line above the lower end of the first base portion 64 of the first return ball prevention unit 61 and the lower end of the second base portion 74 of the second return ball prevention unit 71 is connected. No nail 51 is provided in the area. Further, the total number of nails 51a to 51e is constant under any experimental condition. In any experimental condition, the nail 51d to 51g that can cause a collision of the game ball from the game area PT side to the second ball receiving portion 79 is present at a position closest to the second ball receiving portion 79. The distance L5 between the nail 51d and the tip of the second ball receiving portion 79 is constant at 33 mm, and the nail 51d can cause a collision of the game ball from the game area PT side to the second ball receiving portion 79. The distance L6 between the nail 51e existing at a position farthest from the second ball receiving portion 79 and the tip of the second ball receiving portion 79 is constant at 102 mm. In any experimental condition, the configuration, size, and shape of the first return ball prevention unit 61 and the second return ball prevention unit 71 are the same.

  Among the experimental conditions A1 to G4, in the experimental conditions A1 to A3, the shortest distance L1 and the tip distance L2 are changed while the shortest nail distance L3 and the longest nail distance L4 are kept constant. Also, the shortest distance L1 and the tip-to-tip distance between the groups of the experimental conditions B1 to B3, the experimental conditions C1 to C4, the experimental conditions D1 to D4, the experimental conditions E1 to E4, the experimental conditions F1 to F4, and the experimental conditions G1 to G4. The combinations of L2 are different, and the combinations of the shortest nail distance L3 and the longest nail distance L4 are different in each group. In each experimental condition A1 to G4, the maximum value of the longest nail distance L4 increases as the shortest distance L1 and the tip-to-tip distance L2 increase. The arrangement of the nails 51a to 51c that can cause a game ball collision was adjusted.

<Experiment 1>
As experiment 1, using each game board 34 of experimental conditions A1 to A3, the combination of the first return ball prevention piece 63 and the first pedestal portion 64 and the combination of the second return ball prevention piece 73 and the second pedestal portion 74 An experiment in which the game ball is continuously fired at a constant firing strength that causes the game ball to flow down to a position between the first return ball prevention piece 63 and the first pedestal portion 64 and the first By imaging between the combination of the two return ball prevention pieces 73 and the second pedestal portion 74 and visually observing the imaging result, the combination of the first return ball prevention piece 63 and the first pedestal portion 64 and the second return. It was confirmed whether or not a game ball stayed between the combination of the ball prevention piece 73 and the second pedestal 74. In this case, a cycle in which one game ball is fired in 0.4 sec, a cycle in which one game ball is fired in 0.5 sec, and a cycle in which one game ball is fired in 0.6 sec An experiment was conducted for each of the firing periods of a period in which one game ball is fired in 0.7 seconds and a period in which one game ball is fired in 0.8 seconds.

  The experimental results are shown in the explanatory diagram of FIG. In this case, as for the experimental condition A1 in which the shortest distance L1 is less than the diameter of the game ball, the combination of the first return ball prevention piece 63 and the first pedestal portion 64 and the second of course, regardless of the firing period. A game ball cannot pass between the combination of the return ball prevention piece 73 and the second pedestal portion 74, and the combination of the first return ball prevention piece 63 and the first pedestal portion 64 and the second return ball prevention piece 73. And the retention of the game ball occurred between the combination of the second pedestal 74.

  On the other hand, the combination of the first return ball preventing piece 63 and the first pedestal portion 64 and the second return for any of the firing conditions for the experimental condition A2 and the experimental condition A3 where the shortest distance L1 is larger than the diameter of the game ball. A game ball can pass between the combination of the ball prevention piece 73 and the second pedestal 74, and the combination of the first return ball prevention piece 63 and the first pedestal 64 and the second return in the experiment period of 12 hours. The retention of game balls did not occur between the combination of the ball prevention piece 73 and the second pedestal 74.

<Experiment 2>
As experiment 2, each game board 34 of experiment conditions B1 to G4 and a game board 501 for a comparative example not provided with the second return ball prevention unit 71 as shown in FIG. 6 (experiment condition H: L3 = 11 mm, L4 = 150 mm), a game ball is continuously fired over a period of 12 hours at a constant firing strength at which the game ball flows down around the nail 51g and the nail 51e in FIG. The number of game balls flowing into the guide passage 37 after being led to the PT was measured. In detail, the two photosensors are arranged so that the detection range of the game ball in the guide passage 37 is shifted in the direction of the guide passage 37 around the ball outlet 37b in the guide passage 37. Of these two photosensors, from the ball outlet 37b until 0.1 sec elapses after the game ball is detected by the photosensor closer to the ball outlet 37b (ie, the photosensor downstream of the guide passage 37). The number of times that the game ball was detected by the photo sensor on the far side (that is, the photo sensor on the upstream side of the guide passage 37) was measured. In addition, in the experiment, one game ball is fired every 0.4 sec, one game ball is fired every 0.5 sec, and one game ball is fired every 0.6 sec. Each of the firing period, the period in which one game ball is fired in 0.7 sec, and the period in which one game ball is fired in 0.8 sec.

  The result is shown in the explanatory diagram of FIG. In this case, the test conditions B1 to B3, the test conditions C1 to C4, the test conditions D1 to D4, and the test conditions E1 to E4 in which the distance L2 between the tips is 6 times or less the diameter of the game ball is any firing cycle. However, no inflow of game balls from the game area PT side to the guide passage 37 occurred.

  On the other hand, in the experimental conditions F1 to F4 and the experimental conditions G1 to G4 in which the distance L2 between the tips is 7 times or more the diameter of the game ball, the inflow of the game ball from the game area PT side to the guide passage 37 occurred. The inflow of the game ball into the guide passage 37 is caused by the fact that the game ball colliding with the left side of the second ball receiving unit 79 in the situation where the game ball collides with the right side of the second ball receiving unit 79 In the situation where it flows down downward on the left side of 79, the next game ball that has been launched collides with the game ball and collides with the right side of the first ball receiving portion 69. This is considered to be caused by the game ball launched on the left side of the first ball receiving portion 69 colliding with the left side.

  The number of game balls flowing from the game area PT into the guide passage 37 is such that the tip distance L2 is seven times the diameter of the game ball than the experimental conditions G1 to G4 where the tip distance L2 is eight times the diameter of the game ball. The experimental conditions F1 to F4, which are, tend to be less. Moreover, in any of the experimental conditions F1 to F4 and the experimental conditions G1 to G4, the number of game balls flowing into the guide passage 37 tended to increase as the firing cycle was shorter.
