  Hereinafter, in order to clarify the present invention more specifically, embodiments of the present invention will be described in detail with reference to the drawings. In the following description, in principle, the left-right direction refers to the left-right direction viewed from the player.

  FIG. 1 shows a pachinko machine 10 according to an embodiment of the present invention. The pachinko machine 10 includes an outer frame 12 that is framed in a vertically long rectangular shape, and an intermediate frame 14 is assembled to the outer frame 12 in a state of being pivotally supported so as to be freely opened and closed on one side thereof. . Further, on the front side of the middle frame 14, there are a glass frame 18 provided with a glass plate for protecting the game board 16 attached to the middle frame 14 and a dish plate 22 provided with an upper plate 20, respectively. In addition, it is assembled to one side of the middle frame 14 so as to be pivotally supported so as to be freely opened and closed. Furthermore, a lower plate 24 is provided below the upper plate 20, and a firing handle 26 projects from the right side of the lower plate 24. Then, when the player rotates the launch lever 28 that is rotatably attached to the launch handle 26, the game balls stored in the upper plate 20 are passed through a ball feeding mechanism (not shown). After being sent to a launching device (not shown), it is fired toward a game area 30 formed on the game board 16.

  Next, the structure of the game board 16 will be described. The game board 16 includes a game board with a synthetic resin sheet attached to the surface, and a substantially circular game area 30 surrounded by a guide rail 32 fixed to the surface side of the game board includes: A liquid crystal display 34, a start winning device 36, a special variable winning device 38, and the like are provided. Although not shown, the game area 30 of the game number 16 is provided with a large number of game nails, windmills, and the like as is well known.

  When a game ball that has been launched toward the game area 30 and then flowed down the game area 30 wins the start winning device 36, a plurality of special symbols (not shown) are displayed on the display screen of the liquid crystal display 34. The variable display is started, and the variable display of the plurality of special symbols is performed for a predetermined time. After that, when a plurality of special symbols are stopped and displayed in a specific stop display mode, the door 40 that has blocked the entrance of the special variable prize-winning device 38 until then can be opened and closed in accordance with predetermined operating conditions. ing. As a result, the entrance of the special variable prize-winning device 38 is opened, and it is possible to win a game ball in the special variable prize-winning device 38. As a result, the player can obtain profits (prize balls) that cannot be obtained in normal games ) Can be obtained.

  Further, a center decoration 42 as a center accessory for decorating the periphery of the liquid crystal display 34 is disposed around the display screen of the liquid crystal display 34. As shown in FIGS. 2 and 3, the center ornament 42 is integrally formed at an appropriate number of locations on the periphery of the main body frame 44 so that the plate-like mounting portions 46 protrude outward. The structure is structured such that the main body frame 44 is inserted into an attachment hole (not shown) formed in the game board, and is attached from the surface side of the game board by the attachment portion 46. Therefore, in the present embodiment, the size and shape of the cross section of the other opening end of the through hole 48 formed in the main body frame 44 correspond to the size and shape of the display screen of the liquid crystal display 34. The display screen of the liquid crystal display 34 disposed on the back side of the game board 16 (game board) is visible through the through hole 48.

  Furthermore, a flange 50 is formed at one end of the main body frame 44 so as to protrude from the upper side of the through hole 48 to the front side, thereby allowing the front of the display screen of the liquid crystal display 34 to be displayed. The game ball is prevented from flowing down.

  In addition, a warp passage 52 is formed in the center ornament 42 using the inside of the collar 50 and the inside of the main body frame 44, and is formed outside the portion of the collar 50 that is positioned on the left side of the through hole 48. A game ball entered from the warp inlet 54 passes through the warp passage 52 and is guided from the warp outlet 56 to a stage 58 formed on the inner peripheral surface of the lower end of the main body frame 44.

  The stage 58 is formed from one side of the main body frame 44 to an intermediate portion of the main body frame 44 on the inner peripheral surface of the lower end of the main body frame 44. Therefore, the stage 58 of the present embodiment is divided into one side and the other side of the main body frame 44 at the intermediate portion in the depth direction, and the other side is higher than the one side of the main body frame 44. It has become. In the following description, one side of the main body frame 44 in the stage 58 will be referred to as the near side floor 60, and the other side of the main body frame 44 in the stage 58 will be referred to as the back side floor 62.

  The back floor 62 includes a floor surface 64 that extends in the left-right direction and is curved in a wavy shape that is a right-left object centering on the center portion in the left-right direction, and the center portion in the left-right direction of the floor surface 64 is a mountain-shaped portion. On the other hand, the left and right sides of the mountain-shaped portion 66 are valley-shaped portions 68. That is, in the present embodiment, the floor surface 64 of the back floor 62 includes one mountain-shaped portion 66 and two valley-shaped portions 66, 66. Also, a warp outlet 56 is positioned near the left end of the back floor 62 so that the game ball guided from the warp outlet 56 to the stage 58 can roll on the back floor 62. It has become.

  Furthermore, the back side floor 62 is formed with a back side guiding inclined surface 70 that descends toward the back in the mountain-shaped portion 66, and the game ball can roll on the back side guiding inclined surface 70. Thus, the player can enter the entrance 72 formed on the back side with respect to the back side floor 62.

  In this way, the game ball entered into the entrance 72 is guided to the front floor 60 through the ball path 74 as a guide path formed in the main body frame 44. Yes. Therefore, in the present embodiment, the outlet opening 76 as the outlet of the ball passage 74 is formed on the far side in the center in the left-right direction of the front floor 60.

  Further, the back side floor 62 is formed with a front side guide inclined surface 78 that descends toward the front side floor 60 with respect to each of the valley-shaped portions 68, and the front side guide inclined surface 78 forms a back side floor. A game ball that is allowed to roll 62 is guided to the front floor 60.

  Furthermore, a vertical wall 80 that protrudes upward and extends along the left-right direction of the back floor 62 is formed at the end on the near side of the back floor 62. A notch 82 is formed only at a location corresponding to the position where 78 is formed. Thus, the game ball that can roll on the back floor 62 is guided to the front floor 60 only by passing through the front guide inclined surface 78.

  The near-side floor 60 includes a floor surface 84 that is inclined downward from the left and right sides toward the center in the left-right direction. The depth dimension of the floor surface 84 is larger than the floor surface 64 of the back-side floor 62. It is big enough. In addition, a rotating body 86 is disposed at the center in the left-right direction of the back floor 62.

  As shown in FIGS. 4 and 5, the rotating body 86 has a large-diameter outer cylindrical portion 90 with respect to the lower surface of the shade-shaped rotating plate 88 that gradually decreases in diameter from the lower side in the axial direction to the upper side. The small-diameter inner cylindrical portion 92 is integrally formed on the same central axis. In this case, it is desirable that the inclination given to the upper surface 94 of the rotating plate 88 in a direction descending from the center toward the outer peripheral edge is 5 to 10 degrees with respect to the horizontal direction. If the inclination applied to the upper surface 94 of the rotating plate 88 is smaller than 5 degrees and the game ball riding on the rotating body 86 has no momentum to roll, There is a possibility that the ball will stop, and if the inclination attached to the upper surface 94 of the rotating plate 88 is larger than 10 degrees, it becomes difficult for the game ball to ride on the rotating body 86, or This is because even if it rides on the rotator 86, it may not roll toward the opposite side of the rotator 86. Incidentally, in this embodiment, the angle of inclination attached to the upper surface 94 of the rotating plate 88 is set to 6 degrees. A plurality (four in this embodiment) of protrusions 96 are formed on the upper surface 94 of the shade-shaped rotating plate 88 so as to protrude upward.

  Therefore, in the present embodiment, the protrusions 96 that are formed to protrude from the rotating plate 88 are positioned at a predetermined interval in the circumferential direction at the outer peripheral edge of the rotating plate 88 and are adjacent to each other in the circumferential direction. The interval between the two protrusions 96 is set sufficiently larger than the diameter of the game ball. In the present embodiment, each protrusion 96 is formed so as to extend from the outer peripheral edge of the rotating plate 88 toward the center, and the dimension in the extending direction is approximately half the diameter of the rotating plate 88. The size is assumed. As a result, there is a space where the protrusion 96 is not formed in the vicinity of the center of the upper surface 94 of the rotating plate 88, and the space is wide enough to allow the game ball to roll. Therefore, in the present embodiment, the game ball can pass over the entire portion of the upper surface 94 of the rotating plate 88 where the protrusion 96 is not formed.

  Further, each projection 96 is slightly curved in the extending direction, so that the surface on one side in the circumferential direction of each projection 96 is a concave curved surface, while the surface on the other side in the circumferential direction is The surface is a convex curved surface.

  The rotating body 86 having such a structure is inserted into the recess 98 formed in the front side floor 60 from the side where the outer cylinder portion 90 and the inner cylinder portion 92 are formed. It can be accommodated in 98. Therefore, in the present embodiment, the recess 98 is formed in front of the outlet side opening 76 of the ball passage 74, whereby the rotating body 86 is arranged in front of the outlet side opening 76 of the ball passage 74. Yes. Thus, in a state where the rotating body 86 is accommodated in the recess 98, the inner cylindrical portion 92 of the rotating body 86 is extrapolated to the protrusion 100 provided in the recess 98, and the protrusion The tip of the part 100 is brought into contact with the lower surface of the rotating plate 88. Thereby, the rotating body 86 is supported in the recess 98 so as to be rotatable around the central axis of the protrusion 100. Therefore, in the present embodiment, the central axis of the protrusion 100 extends in a substantially vertical direction, and thereby the rotating body 86 is rotatable around a rotation central axis extending in a substantially vertical direction.

  Further, in a state where the rotating body 86 is accommodated in the recess 98, the upper surface 94 of the rotating plate 88 in the rotating body 86 is a position where the outer peripheral edge portion is slightly higher than the floor surface 84 of the near-side floor 60. And the clearance dimension between the outer peripheral surface of the rotating plate 88 and the inner peripheral surface of the recess 98 is sufficiently smaller than the diameter of the game ball, whereby the floor surface 84 of the floor 60 on the front side of the game ball. To the upper surface 94 of the rotating plate 88 and from the upper surface 94 of the rotating plate 88 to the floor surface 84 of the near-side floor 60 can be easily performed.

  Furthermore, a locking tooth 102 is formed on the outer peripheral surface of the outer cylindrical portion 90 of the rotating body 86. Under the state where the rotating body 86 is housed in the recess 98 as described above, the outer cylinder. A relay gear 104 is meshed with the locking teeth 102 formed on the outer peripheral surface of the portion 90. An output gear 108 fixed to the output shaft of the drive motor 106 is meshed with the relay gear 104. As a result, the driving force of the drive motor 106 is transmitted to the rotating body 86 via the output gear 108 and the relay gear 104. As a result, the rotating center shaft extends in the substantially vertical direction. It can be rotated around. In the present embodiment, a conventionally known DC motor is employed as the drive motor 106.

  Therefore, in the present embodiment, the rotating body 86 is rotated toward the direction in which the concave curved surface of the projection 96 is formed. As a result, in the present embodiment, the rotating body 86 is rotated in the counterclockwise direction. In the present embodiment, the rotation speed of the rotating body 86 is 10 to 15 rotations per minute.

  In addition, by rotating the rotating body 86 in this way, the front side of the outlet opening 76 of the ball passage 74 is positioned between two protrusions 96 that are adjacent in the circumferential direction on the upper surface 94 of the rotating plate 88. Rotating body crossing passage 110 configured to include a portion that is squeezed and opposed to each other across the center of rotating plate 88 and a portion that is not formed with projection 96 near the center of upper surface 94 of rotating plate 88. However, at every predetermined period (in this embodiment, every time the rotator rotates 1/4), the rotator 86 is sandwiched from the exit side opening 76 of the sphere passage 74 and is opposite to the exit side opening 76 of the sphere passage 74. It is designed to appear so as to extend linearly.

  The drive motor 106 is fixed with respect to the main body frame 44. In addition, the relay gear 104 is arranged in a state of being rotatable around a support pin fixed by, for example, the main body frame 44 and an attachment member fixed to the main body frame 44, although not explicitly shown in the drawing. It has become so.

  Furthermore, a vertical wall 112 that protrudes upward and extends along the left-right direction of the front floor 60 is formed at the front-side end portion of the front-side floor 60. Thus, three notches 114, 116, and 118 are formed. In particular, in the present embodiment, the middle notch 116 among these three notches 114, 116, 118 is formed on the opposite side of the exit opening 76 of the spherical passage 74 with the rotating body 86 interposed therebetween, and the notch A start winning device 36 is arranged below the position where 116 is formed. Therefore, in this embodiment, the game ball released from the notch 116 to the game area 30 is easy to win the start winning device 36. In addition, the notches 114 and 118 formed at both ends of the three notches 114, 116, and 118 are formed at positions that sandwich the rotating body 86 when the center ornament 42 is viewed from the front.

  Further, although not necessarily clear in the drawing, the floor surface 84 of the front side floor 60 is a central portion in the left-right direction, and around the recess 98 in which the rotating body 86 is accommodated, the vertical wall 112. Of the game balls that are allowed to roll on the front floor 60, the game area 30 passes through the middle notch 116 and is inclined to each of the two formed notches 114 and 118. A game ball that has not been released passes through one of the notches 114 and 118 at both ends, and is released into the game area 30. The game ball released to the game area 30 through any one of these notches 114 and 118 has no start winning device 36 positioned below these notches 114 and 118. It is difficult to win 36.

  By the way, in the present embodiment, the driving of the rotating body 86 by the drive motor 106 as described above is started when power is supplied to the pachinko machine 10, and power is supplied to the pachinko machine 10. As long as it is, the drive of the rotating body 86 by the drive motor 106 is continued.

  More specifically, the pachinko machine 10 of the present embodiment includes a main control configured to include a CPU that executes control processing, a ROM that stores control programs, and a RAM that stores data necessary for the control processing. The CPU which comprises the circuit and constitutes the main control circuit generates data necessary for the control processing based on the input signal from the start winning switch provided in the start winning device 36 and the like. A game process is executed by transmitting to a display control circuit or the like that controls the variation display or the like of the special symbol on the liquid crystal display 34 and causing the display control circuit to perform variation display or the like of the special symbol based on the transmitted data. It is like that. Such game processing is performed according to a control program stored in the ROM each time an interrupt signal generated every predetermined period (for example, 4 ms) is input.

  Then, when the power is turned on to the pachinko machine 10, the CPU prohibits interrupts, performs initial setting of devices around the CPU, etc., and then executes processing performed at the time of power-on to permit interrupts. The game process as described above is executed. In this embodiment, apart from such a process by the CPU, the pachinko machine 10 is driven when the power is supplied to the pachinko machine 10 through the board on which the main control circuit is formed. Supply of power to the motor 106 is started. In other words, in the present embodiment, after the power to the pachinko machine 10 is turned on, the rotating body 86 always rotates in one direction at a constant speed. As is clear from the above description, in the present embodiment, the main control unit is configured by the CPU.

  Subsequently, the operation of the pachinko machine 10 of the present embodiment will be described. In the pachinko machine 10 according to the present embodiment, the game ball is launched toward the game area 30 by the player turning the launch lever 28, and thus the game area 30 is guided to the game area 30. The played game balls are allowed to flow down the game area 30.

  In this case, when a game ball flows down the game area 30 and enters the warp inlet 54 formed in the center ornament 42, the game ball is discharged from the warp outlet 56 to the stage 58 through the warp passage 52. It has become. The game balls discharged from the warp outlet 56 to the stage 58 are allowed to roll on the back floor 62, and when the back floor 62 is rolled, The floor surface 64 curved in a wave shape at 62 gradually reduces the momentum of rolling.

  When the position where the momentum of rolling in the left-right direction on the back side floor 62 is weakened is the position where the back side guide inclined surface 70 is attached, the game ball is moved by the back side guide inclined surface 70. It rolls toward the entrance 72 and enters the entrance 72.

  The game ball that has entered the entrance 72 in this way is guided to the front floor 60 through the ball passage 74. When guided to the front side floor 60, the rotating body crossing passage 110 is straight from the exit side opening 76 of the ball path 74 to the opposite side of the exit side opening 76 of the ball path 74 across the rotating body 86. When the game ball is developed so as to be extended and when the game ball rolls vigorously, the game ball passes through the rotating body crossing passage 110, thereby exiting the ball passage 74. From the side opening 76, the rotating body 86 is sandwiched so as to reach the side opposite to the outlet side opening 76 of the ball passage 74. In this way, the game ball that has reached the opposite side of the outlet passage 76 of the ball passage 74 across the rotating body 86 is discharged from the middle notch 116 to the game area 30 and positioned below the middle notch 116. It is easy to win a winning start winning device 36.

  When the game ball is guided to the near-side floor 60 through the ball passage 74, the rotating body crossing passage 110 is inserted into the ball passage 74 from the outlet opening 76 of the ball passage 74 with the rotating body 86 interposed therebetween. When the protrusion 96 is not expressed so as to extend linearly toward the side opposite to the side opening 76, specifically, when the projection 96 is positioned in front of the outlet side opening 76 of the ball passage 74. The game balls are bounced by the protrusions 96 and guided to the left side of the rotating body 86 on the near-side floor 60 without passing through the rotating body crossing passage 110.

  Further, when the rotor crossing passage 110 is inclined with respect to the depth direction of the near-side floor 60, the game ball has a notch 116 formed in the middle even when passing through the rotor crossing passage 110. The position does not reach, but reaches either of the notches 114 and 118 on both sides. The game balls that have reached either of the notches 114 and 118 on both sides in this way are not positioned on the start winning device 36 because the notches 114 and 118 on both sides are respectively positioned above the starting winning device 36. Winning has become difficult.

  On the other hand, if the position where the momentum of rolling in the left-right direction on the back floor 62 is weakened is the position where the front guide inclined surface 78 is attached, the game ball is moved by the front guide inclined surface 78. It is rolled toward the front side floor 60 and guided to the front side floor 60.

  In this way, the game ball guided to the front floor 60 is provided with the central portion in the left-right direction of the front floor 60, that is, the rotating body 86 due to the inclination applied to the floor surface 84 of the front floor 60. It is designed to roll toward the desired position. Then, when the rolling momentum is weak and it is impossible to ride on the rotating body 86, or although there is momentum in rolling, it hits the protrusion 96 formed on the rotating body 86 so as to ride on the rotating body 86. If not, the game ball is guided toward the position where the notches 114 and 118 are formed along the slope applied to the floor surface 84 of the front floor 60. 114 and 118 are released to the game area 30.

  On the other hand, when there is momentum in rolling and the rider can ride on the rotary body 86 without hitting the protrusion 96 formed to protrude from the rotary body 86, the game ball is on the upper surface 94 of the rotary plate 88 in the rotary body 86. Will be rolled.

  And when there is no momentum in rolling, or there is momentum in rolling, when the upper surface 94 of the rotating body 86 is rolled, the momentum is reduced by hitting the projection 96 or the rolling direction is changed. In the case where it is swollen, it is rolled toward the outer peripheral edge side by the inclination attached to the upper surface 94 of the rotating plate 88 in the rotating body 86, and the protrusion formed on the rotating plate 88 in the middle thereof. Even if it does not hit 96 or hits the projection 96, if it hits the convex curved surface side, the game ball will roll again on the floor surface 84 of the near-side floor 60. . Such a game ball loses the momentum of rolling so that it can ride on the rotating body 86 again, and it does not ride on the rotating body 86 again, and the inclination is given to the floor surface 84 of the front floor 60. The notches 114 and 118 are rolled toward the positions where the notches 114 and 118 are formed, and are discharged from the notches 114 and 118 to the game area 30.

  In this case, when the game ball is rolled on the upper surface 94 of the rotary plate 88 toward the outer peripheral edge side, the rotary body 86 is rotated. Therefore, the game ball is also rotated in the rotational direction of the rotary body 86. Can be moved. Therefore, even if the game ball that has run on the rotating body 86 from the left side of the rotating body 86 on the near-side floor 60 does not hit the protrusion 96, it may be guided to the notch 116 in the middle. The game ball guided to the position where the middle notch 116 is formed in this way is discharged to the game area 30 through the middle notch 116 and passes through the rotating body crossing passage 110. Similarly to the game ball that has reached the position where the middle notch 116 is formed, it is easy to win the start winning device 36 positioned below the middle notch 116. That is, in the present embodiment, even when the entrance floor 72 is not entered when the back floor 60 is rolled, as with the game balls entered into the entrance 72, The game ball may be guided to the position where the middle notch 116 is formed.

  On the other hand, the game ball that hits the concave curved surface side of the projection 96 when the roller is rolled toward the outer peripheral edge side by the inclination applied to the upper surface 94 of the rotating plate 88 is the concave curved surface of the projection 96. When rotating toward the outer peripheral edge of the rotating plate 88 while hitting, the rotating body 86 is rotated, so that the rotating body 86 is also moved in the rotating direction. In this case, the game ball riding on the rotating body 86 from the portion on the left side of the front floor 60 where the rotating body 86 is disposed faces the left side portion of the front floor 60 of the rotating body 86 toward the middle notch 116. However, there is a case where it is guided toward the middle notch 116, but a game that rides on the rotating body 86 from a portion on the right side of the position on the front floor 60 where the rotating body 86 is disposed. Since the right portion of the front floor 60 of the rotating body 86 is rotated toward the opposite side of the notch 116, that is, toward the exit opening 76 of the ball passage 74, the sphere is directed toward the notch 116 in the middle. There is no case of being guided.

  The game ball guided to the middle notch 116 by the projection 96 formed to protrude from the rotating body 86 is discharged from the middle notch 116 to the game area 30.

  In addition, a game ball that rides on the rotating body 86 from a portion on the right side of the front floor 60 where the rotating body 86 is disposed may be guided toward the exit opening 76 of the ball passage 74 by the protrusion 96. is there. In this case, the game ball once enters the ball passage 74 from the outlet opening 76 of the ball passage 74, but is guided to the front floor 60 by the inclination attached to the ball passage 74. . At this time, when the game ball is vigorous and reaches the position where the middle notch 116 is formed through the rotating body crossing passage 110, the game ball is released from the middle notch 116 to the game area 30. It has become.

  In addition, the game ball which has momentum in rolling and rolls toward the side opposite to the one riding on the rotating body 86 hits the projection 96 in the middle, and moves along the concave curved surface of the projection 96. However, the rotating body 86 may be guided in the rotation direction. In this case, the game ball riding on the rotating body 86 from the portion positioned on the left side of the position on the front floor 60 where the rotating body 86 is disposed is from the position on the front floor 60 where the rotating body 86 is disposed. In this case, the right side portion of the front floor 60 of the rotating body 86 is rotated toward the side opposite to the side where the middle notch 116 is formed. Therefore, the game ball is not guided to the middle notch 116. On the other hand, the game ball riding on the rotating body 86 from the portion positioned on the right side of the position on the front floor 60 where the rotating body 86 is disposed is from the position on the front floor 60 where the rotating body 86 is disposed. In this case, the left side portion of the front floor 60 of the rotating body 86 is rotated toward the side where the middle notch 116 is formed. The sphere may be guided in the middle notch 116.

  Furthermore, if the game ball does not hit the protrusion 96 while it is rolling toward the opposite side of the rotating body 86, the gaming ball will run on the rotating body 86. The front side floor 60 on the opposite side to the one is rolled.

  In the pachinko machine 10 having the above-described structure, a game ball that is rolled on the floor surface 64 of the back side floor 62 that is curved in a wave shape is guided by the back side guide inclined surface 70 to enter the entrance 72. , And is guided to the front floor 60 through the ball passage 74 and further guided to the position where the middle notch 116 is formed through the rotating body crossing passage 110. Since it is easy to win a prize, it is fun to see the movement of a game ball rolled on the floor surface 64 of the back floor 62, and the game ball guided to the front floor 60 through the ball passage 74 It is possible to give the player both enjoyment of watching the movement of the player.

  In the present embodiment, even a game ball guided to the front floor 60 by the front guide inclined surface 78 is located at the position where the rotating body 86 is disposed on the floor surface 84 of the front floor 60. Since the downward slope is attached, the game ball may be guided toward the position where the middle notch 116 is formed by the protrusion 96 provided on the rotating body 86, and thereby the front side The player can enjoy watching the movement of the game ball guided to the near-side floor 60 by the guide inclined surface 78.

  Further, in the present embodiment, the rotational drive of the rotating body 86 by the drive motor 106 is started when the pachinko machine 10 is turned on, and the gaming operation of the pachinko machine 10 is entirely performed. When the CPU that controls the CPU executes the game process based on the interrupt signal, the CPU does not monitor the operation control of the drive motor 106, and the CPU executes the game process. The burden on the occasion can be reduced.
