Description

  The present invention includes an accessory device that is mounted on a game board surface and provided with a ball discharge port, and a winning port that is positioned below the ball discharge port and into which game balls discharged from the ball discharge port are guided. It relates to pachinko machines.

  Conventionally, in this type of pachinko gaming machine, for example, a display device having a display unit that displays a variable display of characters, numbers, symbols, etc. is mounted as a bonus device at the center of the game board, and below that Is a start winning opening as a winning opening that changes the information on the display unit when a game ball wins, and the information on the display unit stops below it and the information when it stops is, for example, “777”. In such a case, a configuration in which a winning device that is a big hit state and can obtain a large number of winning balls at a time under certain conditions is gaining popularity (see, for example, Patent Document 1).

  Usually, the display device is provided with a stage projecting forward at the front lower side of the display unit, and on both sides of the display unit, there are ball guide paths for receiving the game balls flowing down the game board surface and guiding them to the upper surface of the stage. Is provided. The upper surface of the stage is formed into a gentle chevron, a guide groove whose bottom surface is inclined downward is provided at the approximate center, and an opening through which a game ball flows is formed at the rear end. The opening communicates with a discharge passage provided therebelow, and the lower end of the discharge passage communicates with a ball discharge port positioned directly above the start winning port.

Then, for example, a game ball flowing down the game board surface and received in the ball guide passage is guided to the upper surface of the stage and falls downward from its front edge while moving on the upper surface. Among these, a lucky game ball will win the start winning opening, but the possibility is very low. On the other hand, while playing on the upper surface of the stage, the game ball that happens to enter the opening from the guide groove is discharged from the ball discharge port via the discharge passage. The game balls discharged from the ball discharge port are set so that the probability of winning at the start winning port is very high. Therefore, when a game ball enters the opening, the player has a strong sense of expectation that he will win the start winning port through the ball discharge port.

  Next, the display device 7 will be described in detail. As shown in FIGS. 2 and 3, the display device 7 includes an attachment plate 18 having an opening 17 in the center and attached to the surface of the game board 5. On the rear side of the mounting plate 18, an inner frame 19 is provided integrally with the mounting plate 18 so as to be spaced apart slightly wider than the outer diameter of the game ball. In addition, a display 7 b is disposed on the rear side of the inner frame 19, and a display portion 7 a on the front surface thereof faces a square-shaped through hole 19 a opened in the inner frame 19.

  A stage 20 is provided on the rear side of the mounting plate 18 along which the game ball B that has jumped in along the lower side of the opening 17 is placed and freely moves to some extent. Sphere guide passages 21 and 21 called so-called warp passages are provided along both sides of the opening 17. A ball inflow port 22 is formed at the upper end of each ball guide passage 21 to allow the game balls B flowing down the surface of the game board 3 to flow into the ball guide passage 21. A sphere outlet 23 connected to the upper surface 20 is opened.

  The upper surface of the stage 20 is formed so that the central portion protrudes in a gentle mountain shape, and a guide groove 24 whose bottom surface is inclined downward is provided at the highest portion, and the game ball B is formed in the inner frame 19 at the rear end. Is opened. The opening 25 communicates with a discharge passage 26 provided therebelow, and the lower end of the discharge passage 26 communicates with a ball discharge port 27 formed at the lower center of the front surface of the mounting plate 18. The start winning port 8 is projected and located on the same vertical line as the ball discharge port 27 and is mounted on the game board 5 surface below it. The standing position where the game ball is difficult to win and the game ball easy to win are reversed. It has a pair of movable wing pieces 8a, 8a that rotate to an inclined position that becomes an eight-letter shape. The game ball B discharged from the ball discharge port 27 is set so that the probability of winning the start winning port 8 is very high.

  Therefore, for example, the game ball B that flows down the surface of the game board 5 and flows into the ball guide passage 21 from the ball inlet 22 is guided to the upper surface of the stage 20 from the ball outlet 23 at the lower end, and the upper surface is To move. During this time, the game ball B that happens to fit in the guide groove 24 and enters the opening 25 is discharged from the ball discharge port 27 through the discharge passage 26.

  Protection for reliably guiding the game ball B discharged from the ball discharge port 27 behind the ball discharge port 27 below the discharge passage 26 to the start winning port 8 without being obstructed by other game balls. A member 28 is disposed. As shown in FIG. 4, the protective member 28 is disposed on the lower edge of the ball discharge port 27 in parallel with the game board 5 surface and horizontally, and a support shaft 29 that rotates freely in the front-rear direction and both ends of the support shaft 29. It consists of a pair of protective plates 30, 30 fixed to the support shaft 29 at right angles. Each guard plate 30 has a side fan shape and a size that can hide one game ball, and a support shaft 29 is fixed to one side thereof. In the mounting plate 18, vertically long holes 31, 31 are formed on both sides of the ball discharge port 27, and each protection plate 30 is moved back and forth through each vertically long hole 31 along with the rotation of the support shaft 29 to the front side. Advancing and retreating in the direction, more precisely rotating in the front-rear direction, moving forward or backward, encloses both sides of the ball outlet 27.

  More specifically, a weight 32 having a predetermined weight is embedded in each of the protection plates 30 at an eccentric position, and the protection member 28 is always urged to rotate backward. In addition, a pair of projecting pieces 33 a and 33 b are integrally provided on the outer peripheral surface of the support shaft 29 so that the positions thereof are changed by approximately 180 degrees. When the protective member 28 rotates rearward and the one projecting piece 33 a comes into contact with the lower edge of the ball discharge port 27 and the protective member 28 stops, the other projecting piece 33 b serves as the bottom surface of the discharge passage 26. It protrudes slightly upward.

  Therefore, when the game ball B flowing down in the discharge passage 26 is discharged from the ball discharge port 27, the game ball B pushes down the other protruding piece 33b. As a result, the protective member 28 is rotated to the front side against the urging thereof, and the protective plates 30, 30 are simultaneously moved forward from the vertically elongated holes 31, 31 simultaneously with the discharge of the game ball B from the ball discharge port 27. It stops when the other protruding piece 33b comes into contact with the lower end edge of the ball discharge port 27. Further, when the game ball B is detached from the other protrusion 33b and dropped, the protection member 28 is rotated to the rear side by its own weight and returned to the original position.

  The pachinko gaming machine P according to the present invention has the above configuration, and the operation will be described next. A game ball B that flows down on the surface of the game board 5 as shown in FIG. 3, and is received by the inner frame 19 of the display device 7 from the opening 25 of the stage 20 to the discharge passage 26 as shown in FIG. The inflowing game ball B is discharged from the ball discharge port 27 to the game board 5 surface and guided to the lower start winning port 8.

  At this time, as shown in FIG. 5 (b), when the game ball B reaches the ball discharge port 27, the game ball B pushes down the other projecting piece 33b of the support shaft 29 and biases the protective member 28. Turn it to the front side. As a result, as shown in FIG. 5C, simultaneously with the discharge of the game ball B, the two protection plates 30, 30 protrude forward from both the long holes 31, 31 to surround both sides of the game ball B. Therefore, even if another game ball B flies from the lateral direction in this state and attempts to contact the game ball B, it is blocked by the protection plates 30 and 30, and the game ball B is placed at the lower start winning opening. 8 is surely guided.

  When the game ball B comes off the other projecting piece 33b and reaches the start winning opening 8, the protective member 28 rotates rearward by its own weight and returns to its original position as shown in FIG. ing.

  Thus, in the pachinko gaming machine P according to the present invention, the game ball B discharged from the ball discharge port 27 is protected by the protective member 28 and is surely guided to the starting winning port 8 below it. Therefore, it is possible to enjoy the game without betraying the player's expectation, thereby improving the game service. The protective plate 30 is provided on each of both ends of the support shaft 29. However, the protective plate 30 is fixed to only one end of the support shaft 29 depending on the gauge condition of the game board 5 surface. You may do it.

  In the present embodiment, the protection member 28 is rotated to the rear stop position by its own weight. However, as shown in FIG. A tension spring 35 may be interposed between the one projecting piece 33 a projecting from 29 and the support plate 34 projecting from the rear surface of the mounting plate 18. Then, when the game ball B reaches the ball discharge port 27 as shown in FIG. 6B, the game ball B pushes down the other protrusion 33b of the support shaft 29, and the protection member 28 is pulled to the spring of the spring 35. Rotate forward against the force. As a result, simultaneously with the discharge of the game ball B, the two protection plates 30, 30 protrude forward from both the vertically long holes 31, 31 and surround both sides of the game ball B.

  In addition, after the game ball B is discharged, the protection member 28 rotated to the front side by the tension spring 35 is returned to the rear stop position again. The spring force of the tension spring 35 is such that the protection member 28 rotates depending on the game ball B discharged from the ball discharge port 27, and after the game ball B is discharged, the protection member 28 returns to the original position on the rear side. Its strength is set to return.

  FIGS. 7A and 7B also show other embodiments. In this embodiment, as shown in FIG. 7 (a), a hook-shaped hook rod 37 is projected from the outer peripheral surface of the support shaft. On the other hand, a horizontal shaft rod 39 is pivotally supported on a support plate 38 extending rearward from the rear surface of the mounting plate 18, and an action rod 40 that rotates freely back and forth within a vertical plane is integrated with the shaft rod 39. Is provided. In addition, a solenoid 41 is attached to the rear surface of the game board 5 as an electrical driving means in which the plunger 41a slides in the vertical direction.

  One end (front end) of the working rod 40 is locked to the hook rod 37, and the other end (rear end) is locked to the upper end of the plunger 41 a of the solenoid 41. Further, a ball detector 42 (for example, a photo switch) for detecting the game ball B discharged therefrom is disposed at a predetermined position of the discharge passage 26. Then, by detecting the game ball B flowing down the discharge passage 26 by the ball detector 42, as shown in FIG. 7B, the solenoid 41 is excited to rotate the protective member 28 forward. . Further, after a lapse of a predetermined time (for example, 1 second) after the ball detector 42 detects the game ball B, the solenoid 41 is demagnetized and the protective member 28 is rotated rearward to return to the original position. To.

  In any of these other embodiments, the game ball B discharged from the ball discharge port 27 may temporarily come in contact with the game ball B by another game ball flying from the lateral direction. Is prevented by the protection plates 30 and 30 and is surely guided to the lower start winning opening 8. In the other embodiments, since the configuration is almost the same as that of the present embodiment, the same parts are denoted by the same reference numerals, and detailed description thereof is omitted.
