As shown in FIGS. 4A and 4B, the movable blades 15a and 15b are fixed to the tips of the support shafts 16a and 16b, and the cranks 17a and 17b are fixed to the rear ends of the support shafts 16a and 16b. It is installed. Reference numerals 18a and 18b are electric actuators (solenoids) fixed vertically inside the center accessory 4, and 19a and 19b are operating pieces fixed to plungers of the electric actuators 18a and 18b. Reference numerals 20a and 20b denote tilting pieces that are supported so as to be tiltable by pivotally supporting the bearing portions 21a and 21b. The pins 22a and 22b protruding from the tilting pieces 20a and 20b are loosely fitted into the laterally long holes 23a and 23b formed in the operating pieces 19a and 19b, and the pins 24a protruding from the tips of the cranks 17a and 17b. , 24b are loosely fitted into the long holes 25a, 25b formed in the tilting pieces 20a, 20b.

  When the electric actuators 18a and 18b are excited and the operating pieces 19a and 19b are moved upward, the tilting pieces 20a and 20b are tilted upward to rotate the support shafts 16a and 16b in the direction of the arrow as shown in FIG. The movable blades 15a and 15b change from the standing shape shown in FIG. Accordingly, the ball inlets 14a and 14b are opened as shown in FIG. 2 by chain lines, and the game balls can flow into the center accessory 4 from the ball inlets 14a and 14b. Reference numeral 26 denotes a ball floating passage formed in a mountain shape in the center accessory 4 and inside the ball inlets 14a and 14b. Reference numerals 27a and 27b denote ball detection switches provided at both ends of the ball play passage 26 for detecting the game balls flowing into the center accessory 4 from the ball inlets 14a and 14b. The game balls are the ball detection switches. It falls from the annular holes 27a and 27b to the concave passage 28 formed in the lower stage thereof.

  Further, as shown in FIG. 2, a window hole 29 having a width that allows three game balls to pass side by side is formed in the central portion of the rear side wall of the concave passage 28. A ball stop device 30 is provided. As shown in FIGS. 5 (a) and 5 (b), the ball stopping device 30 is fixed vertically to the inner center of the center member 4 and the distributing member 31 pivotally mounted at the upper end and swinging freely back and forth. An electric actuator (solenoid) 32 provided, and a regulating member 33 fixed to the plunger of the electric actuator 32 and linked to the distributing member 31. The sorting member 31 is provided with a lid piece 31a for opening and closing the upper surface of a ball drop opening 38, which will be described later, at the lower end, and a pin 34a is provided at the tip of an arm piece 34 protruding rearward from the shaft support portion. On the other hand, the regulating member 33 is provided with a movable piece 35 protruding forward at the upper end thereof, and the pin 34a of the arm piece 34 is engaged with a bifurcated portion 36 at the distal end of the movable piece 35. Further, the lower end of the regulating member 33 is bent forward and a ball stop piece 37 is provided. The front end portion of the ball stop piece 37 is located below the ball drop opening 38. When the restricting member 33 is raised, the ball stop piece 37 is positioned directly below the ball drop opening 38 and its lower surface is closed to support the game ball that has entered the ball stop piece 37 from below. In this state, when the regulating member 33 is lowered, the lower surface of the ball drop opening 38 is opened, and the game ball loses its support and falls.

  Below the sorting member 31 in the ball stopping device 30, a ball drop opening 38 that opens and closes so as to receive a game ball by the swinging motion of the sorting member 31 is provided. The annular hole of the switch 39 (not shown in FIG. 5) is matched. The ball outlet 38 is opened on the bottom wall corresponding to the branch point of the warp passages 40a, 40b extending to the left and right sides. These warp passages 40a and 40b are bent downward on both sides, and provided at the lower ends thereof are ball outlets 41a and 41b located on both upper surfaces of the inclined shelf 52 described later. The parts surrounded by these warp passages 40a and 40b are a pair of front and rear transparent parts spaced apart by a width slightly wider than the diameter of the game ball so that the player can visually recognize the display 48 located on the rear side from the front side. The light-transmitting region 42 is stretched with a resin plate.

  A central vertical passage 43 is formed between the transparent resin plates in the light-transmitting region 42 and is located below the ball outlet 38 and guides a game ball falling from the ball outlet 38 downward. The central vertical passage 43 is provided with a first ball receiving piece 44a that temporarily receives a game ball that protrudes inward and drops in the middle of the passage, and a second ball receiving piece 44b that is positioned below the first ball receiving piece 44b. These first and second ball receiving pieces 44a and 44b are provided in different positions, and their upper surfaces are inclined downward toward the center of the central longitudinal passage 43, so that even if a game ball gets on the upper surface, it cannot be stopped. It comes to fall. Further, the upper surface of the second ball receiving piece 44b is recessed in an arc shape, and the lower end discharge port 43a for discharging the game ball is located on either side along the longitudinal direction of the ball rolling passage 45, in this case, on the right side in FIG. , A third ball receiving piece 44c is provided.

  A ball rolling passage 45 that receives a game ball falling from the lower end of the central vertical passage 43 is provided at a lower portion between both transparent resin plates. The ball rolling passage 45 has a bottom wall whose upper surface is the lowest at the central portion, which is a position directly below the central vertical passage 43, and both sides thereof are gently inclined downward toward the central portion. In addition, a ball feeding port 46 is provided on the rear side wall of the central portion of the central vertical passage 43 to allow the game ball to drop to the substantially central portion in the left-right width direction of the inclined shelf 52.

  When the electric actuator 32 of the ball retaining device 30 is demagnetized, as shown in FIG. 5 (a), the plunger projects downward, the restricting member 33 stops at the lowered position, and the distributing member 31 moves forward. It swings and protrudes to block the upper surface of the ball outlet 38. Therefore, in this state, the game ball guided from the concave passage 28 through the window hole 29 is distributed to the left or right by the distribution member 31, flows in the warp passages 40a and 40b, and has a ball outlet 41a at the lower end thereof. , 41b and fall on the upper surface of the inclined shelf 52. In this state, the ball stop piece 37 at the lower end of the restricting member 33 intervenes in the central vertical passage 43 through the vertical groove 47 formed in the rear side wall of the central vertical passage 43, and the first ball receiving piece 44a. The game ball on the upper surface of the first ball receiving piece 44a is supported so that it does not fall below it.

  On the other hand, when the electric actuator 32 is energized, the plunger contracts upward as shown in FIG. 5 (b), the restricting member 33 stops at the raised position, and at the same time the distribution member 31 swings backward. The upper surface of the ball outlet 38 is opened so that a game ball can enter. Therefore, the game ball guided rearward from the concave passage 28 through the window hole 29 in this state easily enters the ball outlet 38. The game ball that has entered the ball drop opening 38 is supported at its lower surface by a ball stop piece 37 at the lower end of the regulating member 33 so that it does not fall into the central longitudinal passage 43 unless the electric actuator 32 is demagnetized and the regulating member 33 is lowered. It has become. The game balls that enter the window hole 29 after that are distributed by the game balls held in the ball drop opening 38 and flow into one of the warp passages 40a and 40b.

  In this state, when the electric actuator 32 is demagnetized, the restricting member 33 is lowered, and the game ball held in the ball drop opening 38 by the restricting member 33 falls onto the upper surface of the first ball receiving piece 44a. At the same time, the sorting member 31 protrudes forward and closes the upper surface of the ball outlet 38. At this time, the game ball is supported by the regulating member 33 and held on the upper surface of the first ball receiving piece 44a. When the electric actuator 32 is energized again, the regulating member 33 rises and the sorting member 31 moves backward to open the upper surface of the ball drop opening 38. At the same time, the game ball that has been on the upper surface of the first ball receiving piece 44a is released from the restricting member 33, and temporarily rides on the upper surface of the second ball receiving piece 44b, and further on the upper surface of the third ball receiving piece 44c below it. As shown in FIG. 6 (a), it falls from the lower end discharge port 43a to the upper surface of the bottom wall of the ball rolling passage 45.

  Since the lower end discharge port 43a of the third ball receiving piece 44c faces the right side when the ball rolling passage 45 is viewed from the front as shown in FIG. 2, the game balls discharged from the ball rolling passage 45 are likely to gain momentum. Therefore, since the upper surface of the bottom wall of the ball rolling passage 45 is gently inclined downward toward the central portion, the game ball is left and right centered on the central portion as shown by the chain line in FIG. Reciprocates while decaying to the side. Then, the game ball finally approaches the center and falls to the center of the upper surface of the inclined shelf 52 through the ball feed port 46. Both side edges along the central vertical passage 43 of the ball feeding port 46 protrude forward as shown in FIG. 6 (b), and both front sides starting from both protrusions respectively follow the ball rolling passage 45. The taper surface 45a is gradually inclined backward as it goes outward.

  Thereby, the game ball that reciprocates left and right around the ball rolling passage 45 about the ball rolling passage 46 is guided so as to come into contact with the tapered surface 45a and be separated from the ball feeding port 46 as it approaches the ball feeding port 46. The Therefore, for example, the game ball stops by hitting both inner edges of the ball feeding port 46, and the reciprocation does not stop there, and the player can enjoy the movement of the game ball for a long time.

  A game room 50 is formed below the ball rolling passage 45 in the center accessory 4 so that the inside can be seen from the front side so as to communicate with a window opening 49 formed in the mounting board 12. As shown in FIG. 7, in the game room 50, a doll 51 as a decorative body is provided in a protruding shape at the center of the rear side front wall 50a. In addition, an inclined shelf 52 that is arranged in a transverse shape and gently tilts downward is provided at an intermediate height position in the game room 50. The rear edge of the inclined shelf 52 is opposed to the doll 51 with a gap 53 at which the game ball can fall. The floor surface 54 of the game room 50 is formed in a gentle forward inclined shape, and a special winning opening 55 is provided at the center of the front edge of the game room 50, and slightly wide ordinary winning openings 56, 56 are provided on both sides of the special winning opening 55. It is formed. The special winning opening 55 is provided with a ball detection switch 57. In the normal winning openings 56, 56, a ball detection switch (not shown) is disposed on the downstream side thereof.

  As shown in FIG. 8, a pocket-shaped advance / retreat type electric member 58 provided so as to be able to repeatedly advance forward is attached to the abdomen of the doll 51. The advancing / retracting type electric member 58 is horizontally disposed and is provided with a pocket portion 58a having an upper surface opened at the front end. On the rear side of the rear front wall 50a, an electric actuator (solenoid) 59 connected to the forward / backward movement type electric member 58 and operating the forward / backward movement type electric member 58 is horizontally disposed. Further, a passage 60 through which a game ball can pass is formed on the back side of the rear front wall 50 a corresponding to the rear side of the doll 51, and the passage 60 communicates with a discharge port 61 opened in the crotch portion of the doll 51. Yes. A stop lever 62 is disposed below the floor surface 54 and is supported so as to tilt up and down in the vertical plane with the pivot 64 as a fulcrum by the operation of the electric actuator (solenoid) 63. Then, the tip 62a of the stop lever 62 appears and disappears from the floor surface 54 so that the tip 62a of the stop lever 62 faces the discharge port 61 due to the upward / downward tilt, and the game ball released from the discharge port 61 is temporarily stopped by the stop lever 62. It is supposed to be. In addition, sub discharge ports 65 communicating with the passage 60 are opened on both sides of the discharge port 61 and on the rear front wall 50a.

  As shown in FIGS. 2 and 7, hemispherical rotary electric members 66 are provided on both sides of the doll 51 and on both sides of the inclined shelf 52. The rotary electric member 66 shown in FIG. 9 is arranged on the right side when the center accessory 4 is viewed from the front as shown in FIG. 2, but the rotary electric member 66 arranged on the left side is arranged on the right side. Since the configuration is the same as that described, the illustration is omitted. The spherical surface of the rotary electric member 66 is supported by a rotary shaft 67 and a motor 68 with a speed reducer is connected to the rear end of the rotary shaft 67. The rotary electric member 66 has a through-hole 69 through which a game ball can pass at equal intervals. Further, a rotating disk 81 is fixed to the rotating shaft 67 so as to be perpendicular to the rotating shaft 67, and radially and equidistantly around the rotating shaft 67 around the outer peripheral edge of the rotating disk 81. A plurality of slits 82 are provided. A detector 83 provided with a projector and a light receiver is disposed on one side of the rotating disk 81 so as to sandwich the outer peripheral edge of the rotating disk 81 from the front side and the rear side.

  The rotary electric member 66 is always rotated in the direction of the arrow in FIG. 9, that is, in the clockwise direction when the center accessory 4 is viewed from the front, by driving the motor 68 with a speed reducer. The rotating electric member 66 that is rotating can be stopped by detecting the slit 82 with the detector 83, but is always stopped at the same position. As described above, the rotation-type electric member 66 is always stopped at the same position so that there is no variation in the winning probability of winning the special winning opening 55 of the game ball that has entered the center accessory 4. This is for the purpose of illustration. On the other hand, the rotary electric member 66 arranged on the left side rotates in the counterclockwise direction when the center accessory 4 is viewed from the front as shown in FIG. Then, the game ball that has dropped onto the upper surface of the inclined shelf 52 falls to the floor surface 54 from the interval 53, enters the inner side through the through hole 69 of the rotary electric member 66, and either through hole 69. To the floor surface 54 via the curved shelf 70 below.

  Further, push members 71 are arranged on both sides of the doll 51 on the rear front wall 50 a of the game room 50. Since these push-out members 71 have the same structure, FIGS. 10 (a) and 10 (b) show only the center accessory 4 as shown in FIG. The push-out member 71 has a support shaft 74 projecting from the front surface of a sliding frame 73 having a support hole 72 penetrating at both ends, and a contact piece 75 imitating a human hand at the tip, that is, the front end of the support shaft 74. It is composed by fixing. On the other hand, a support frame 76 is fixed to the rear side front wall 50a of the game room 50. The support frame 76 is provided with a shaft hole 77 penetrating horizontally in the front-rear direction of the rear front wall 50a. Further, on the rear surfaces of both sides of the support frame 76, support rods 79 that are parallel to the central axis of the shaft hole 77 and wound with the compression springs 78 are protruded rearward. Then, the support shaft 74 is inserted into the shaft hole 77, and both support rods 79 are inserted into the support holes 72. An electric actuator (solenoid) 80 that pushes the sliding frame 73 forward against the bias of the compression spring 78 is disposed horizontally on the rear side of the sliding frame 73.

  Therefore, when the electric actuator 80 is demagnetized, the sliding frame 73 is retracted by the bias of the compression spring 78 as shown in FIG. Close to the front of 50a. On the other hand, when the electric actuator 80 is excited, the plunger moves forward and pushes the sliding frame 73 forward against the biasing force of the compression spring 78 as shown in FIG. Thereby, the contact piece 75 protrudes forward and approaches the rear end edge of the inclined shelf 52. The gap between the rear edge and the contact piece 74 has a dimension that the game ball cannot pass through, and the game ball that hits the contact piece 75 that rolls backward on the upper surface of the inclined shelf 52 and moves is inclined. The upper surface of the shelf 52 is pushed back to the front side. The front surfaces of the two abutting pieces 75 are set to face the central doll 51 side rather than facing the front. Therefore, the game ball pushed back to the corresponding piece 75 is provided with a glass plate (not shown) of the transparent plate holding frame (not shown) covering the front surface of the pachinko gaming machine. When there is a front transparent wall to be closed, it is easy to flow down toward the pocket portion 85a by hitting the front transparent wall.

  The center accessory 4 of the pachinko gaming machine according to the present invention has the above-described configuration. For example, when a game ball driven into the surface of the game board 1 wins the start winning opening 7a, 7b or the electric opening / closing start winning opening 8, Patterns such as numbers, characters, and figures detected and displayed on the display 48 start to fluctuate. The player can see the design through the light-transmitting area 42. In the electric opening / closing start winning opening 8, a lottery is performed when the game ball passes through the upper passage gate 8a, and when the lottery is won, the electric opening / closing starting winning opening 8 is opened and closed once.

  Then, the fluctuating symbol stops at a specific symbol (for example, “111”, “222”, “777”). Therefore, when the specific symbol stops at “111”, the movable blades 15a and 15b perform the opening / closing operation once. When the specific symbol stops at “222”, the movable blades 15a and 15b perform the opening / closing operation twice. On the other hand, when the specific symbols are aligned to “777”, it becomes a special gaming state advantageous to the player, and the movable blades 15a and 15b repeat opening and closing a predetermined number of times per round, and then the round is continued a predetermined number of times. You can get many prize balls at once. After the round, the original state is restored.

  When the movable blades 15a and 15b are opened once or twice, if a game ball is won at the ball inlets 14a and 14b, the game ball is detected by passing through the ball detection switches 27a and 27b. As a result, except for the electric actuators 18a and 18b that operate the movable blades 15a and 15b, the other electric actuators 32, 59, 63, and 80 are driven, and the distribution member 31, the regulating member 33, and the forward and backward movement type electric member 58 are driven. The stop lever 62 and the pushing member 71 are appropriately operated according to the set time. In addition, the pushing member 71 repeats a forward projecting operation a plurality of times at the same time on the left and right sides from when the game ball is won to the center accessory 4 until it is discharged.

  The game balls detected through the ball detection switches 27 a and 27 b at the ball inlets 14 a and 14 b enter the concave passage 28. Next, this game ball flows backward from the window hole 29, but when the electric actuator 32 is demagnetized and the upper surface of the ball drop opening 38 is blocked by the distribution member 31, the game ball is distributed by the lid piece 31a. Then, it flows into one of the warp passages 40a, 40b, and falls onto the upper surface of the inclined shelf 52 from the ball outlets 41a, 41b at the lower end thereof. On the other hand, when the electric actuator 32 is excited to swing the sorting member 31 rearward and the upper surface of the ball drop opening 38 is opened, the game ball entered from the window hole 29 enters the ball drop opening 38 in a timely manner. The game ball is temporarily held while the electric actuator 32 is excited. Therefore, the subsequent game ball inevitably does not win the ball drop opening 38 and flows into one of the warp passages 40a and 40b.

  When the electric actuator 32 is demagnetized, the regulation member 33 is lowered and the game ball held in the ball drop opening 38 loses support and falls into the central longitudinal passage 43 and is supported by the regulation member 33. It is held on the upper surface of the first ball receiving piece 44a. Further, when the electric actuator 32 is energized, the regulating member 33 rises and the game ball on the upper surface of the first ball receiving piece 44a loses its support and falls, and passes through the second and third ball receiving pieces 44b and 44c to move the ball rolling path. 45 Drops on top. On the upper surface of the ball rolling passage 45, the game ball reciprocates along the ball rolling passage 45 while being attenuated to the left and right around the central portion. The game ball finally attenuated falls from the ball feed port 46 to the upper surface of the inclined shelf 52.

  A game ball that rolls backward on the upper surface of the inclined shelf 52 falls in front of the doll 51 from the interval 53 or contacts the rotating electric member 66 that is positioned on both sides of the upper surface of the inclined shelf 52 and is rotating. It is repelled or enters the through-hole 69 and falls as it is from one of the through-holes 69 onto the curved shelf 70 and is discharged onto the floor surface 54. Then, the game ball rolls forward and wins the normal winning slot 56 or the special winning slot 55. Among these, when the game ball falls from the interval 53, when the electric actuator 59 is excited and the advance / retract type electric member 58 advances and enters the opened pocket portion 58a as shown by the chain line in FIG. Flows down the passage 60 and is led to the discharge port 61 at the crotch part of the doll 51. At this time, when the electric actuator 63 is excited and the upper end of the stop lever 62 protrudes upward from the floor surface 54 as shown by the chain line in FIG. 1, the game ball at the discharge port 61 is held as it is. However, when the electric actuator 63 is demagnetized and the upper end of the stop lever 62 is positioned below the floor 54, the game ball flows down straight and easily wins the special winning opening 55. In this case as well, a special gaming state is established, and the movable blades 15a and 15b are repeatedly opened and closed a predetermined number of times per round, and then the round is continued a predetermined number of times, so that many prize balls can be obtained at one time. After the round, the original state is restored.

  In addition, when the electric actuator 63 is excited and the game ball is held by the stop lever 62 at the discharge port 61, the game ball that enters over the passage 60 through the passage 60 enters the floor surface 54 from the sub discharge port 65. It is discharged and almost wins the normal winning opening 56.

  Therefore, in the middle of the game, the game ball that rolls backward on the upper surface of the inclined shelf 52 but does not approach the center of the inclined shelf 52 where the doll 51 is located falls from the rear edge of the inclined shelf 52. When the pushing member 71 protrudes forward at this time, as shown by a chain line in FIG. 11, the pushing member 71 is pushed against the contact piece 75 and the upper surface of the inclined shelf 52 is pushed back to the front side. In this way, as long as the game ball is pushed back by the contact piece 75, the time for which the game ball stays on the upper surface of the inclined shelf 52 by reciprocating back and forth on the upper surface of the inclined shelf 52 becomes longer. Therefore, the opportunity for the game ball to enter the forward / backward movement type electric member 58, that is, the special winning opening 55 is increased, and the thrill or expectation of whether or not to win the special winning opening 55 can be maintained. This will increase the fun of the game.
