Description

  The present invention relates to a large winning opening device of a pachinko gaming machine configured to have a large winning opening that allows a player to win a game ball at a big hit.

  Conventionally, in a pachinko gaming machine, a big winning opening is opened and a prize ball is awarded to a player by winning the big winning opening at the time of a big win by a lottery accompanying winning at a starting opening. However, it is not desirable that the number of winnings in the big winning opening is larger than a predetermined number. For this reason, with conventional pachinko machines, the number of winning balls at the time of a big hit is not made different, and a predetermined number of winnings can be immediately controlled after a predetermined number of winnings are detected so that excessive winning balls are not allowed. In some cases, the blade member or the ball passage is arranged at a difficult-to-win position of the game ball (see, for example, Patent Documents 1 and 2).

  Alternatively, in a conventional pachinko gaming machine, a wing member or an open / close door is used as a game ball so as to quickly detect a game ball at the time of winning a big prize opening and prevent a predetermined number or more of the prize winning holes from being won. Some of them are moved to a position where it is difficult to win a prize to shift to the next round or the like (for example, see Patent Documents 3 and 4).

  However, in the conventional pachinko gaming machines described in Patent Documents 1 and 2, the blade member or the ball passage is moved to a position where it does not receive the game balls that flow down, so that excessive game balls can enter the big prize opening. Although it can block the ball, it does not speed up the detection of the game ball at the time of winning.

  In addition, in the pachinko gaming machines described in the conventional patent documents 3 and 4, the moving distance of the gaming ball from entering the big winning opening to the winning detection part is shortened, or the moving speed is increased, Although it can be detected quickly, there is room for improvement in that it eliminates the game balls immediately before the detection part immediately after counting the specified number of game balls to be won when the big prize opening is opened so as not to win. was there.

  The present invention solves the above-described problems, and an object of the present invention is to provide a large winning opening device for a pachinko machine that can quickly detect a winning at a large winning opening and can stabilize the number of winning pieces. And

  The term “opening” refers to a period from the occurrence of a jackpot to the start of the first round of jackpot.

  If YES in step S2, the process proceeds to step S3, where it is determined whether or not the opening time, that is, the time from the occurrence of the jackpot to the start of the first round of the jackpot has elapsed. If the process is finished and has elapsed (YES in step S3), the round number R is incremented by “1” (step S4), and then the winning number C to the big prize opening 65 is set to “ After clearing to “0” (step S5), an operation signal is output to the large winning opening solenoid 71, the guide surface portion 61 of the opening / closing member 60 is moved from the non-winning state CL to the winning possible state OP, and then to the winning hole 55. The game ball B that flows down is rolled on the guide surface portion 61 so as to be in an open state in which it can win a prize winning opening 65 (step S6), and the process proceeds to step S7.

  Further, in the above-described step S9, when it is determined whether or not the special winning opening 65 is open, if it is open (YES in step S9), the process proceeds to step S7, and if not open (in step S9). NO), it is determined whether or not ending, and if it is ending (YES in step S12), the process proceeds to step S16, and if not ending (NO in step S12), whether or not the interval time has elapsed. Is determined (step S13). If the interval time has elapsed (YES in step S13), the process proceeds to step S4. If the interval time has not elapsed (NO in step S13), the process ends.

  Note that “ending” means when the jackpot end effect is performed in the image display device 3 after the fifteenth round is ended. The interval time refers to a preset time from the time when the big prize opening 65 is opened until the time when the big prize opening 65 is opened to start the next round.

  Then, in step S7, it is determined whether or not a time period during which the large winning opening 65 in one land can be kept open has elapsed. If not (NO in step S7), the large winning opening 65 is determined. It is determined whether or not the winning number C is a predetermined value “9” (step S8). If the winning number C is not “9”, the process is terminated.

  In step S7, if the opening time has elapsed (YES in step S7), or if the winning number C is “9” (YES in step S8), the process proceeds to step S10 to the big prize opening solenoid 71. The operation signal is stopped and the guide surface 61 of the opening / closing member 60 is placed from the winning state OP to the non-winning state CL so that the game ball B does not win the big winning opening 65 (step S10). Then, the process proceeds to step S11.

  At this time, even if the game ball B is placed on the guide surface portion 61 immediately before the opening portion 66 of the special winning opening 65, the game ball B moves forward from the lower surface of the game ball B and comes off. Therefore, it will fall down without winning the big prize opening 65.

  In step S11, it is determined whether or not the number of rounds R is “15”. If the number of rounds R is not “15” (NO in step S11), the process is terminated and the number of rounds R is “15”. If so (YES in step S11), the round number R is cleared to “0” (step S14), and ending is started (step S15). Thereafter, when the ending time elapses (step S16), the ending ends and the jackpot ends (step S17).

(2) Grand prize opening SW processing (FIG. 16)
In FIG. 16, the game control board 20 adds the winning number C by “1” when the big winning opening SW67 is turned on (step S21), and is a big hit (step S22, step S23), and 15 prize balls commands Is set and transmitted to the payout control board 22 (step S24). The payout control board 22 that has received the 15 prize balls command outputs an operation signal to the payout drive motor 32, and the payout drive motor 32 is driven to pay out 15 prize balls.

  And in the big prize opening device 40 of embodiment, as shown to B of FIG. 6, FIGS. 7-9, B of FIG. 10, B of 11 and B of 12, 12, the opening / closing member 60 is the big prize opening of the drive means 70. If the game ball B flows down from above with the solenoid 71 and the motion conversion mechanism 75 moving to the winning state OP, the game ball B enters the entrance 55 of the frame 50. A large winning opening 65 on the lower side of the guide surface portion 61 is placed on the guide surface portion 61 of the opening / closing member 60, and further the front and rear positions of the front frame portion 51 and the rear frame portion 54 (including the decorative lamp 42) are restricted. Rolling to the side of the opening 66 and winning a prize winning port 65, and also being detected by a prize winning port SW67 as a detecting member, and then passing through a ball passage 69 to a predetermined discharge basket in the game board 1. Will be discharged to the side. Similarly, the succeeding game ball B rolls on the guide surface portion 61 and wins the big prize opening 65 and is detected by the big prize opening SW 67, and then passes through the ball passage 69 and is discharged within the game board 1. It is discharged to the heel side.

  Thereafter, if the game control board 20 as the control means of the pachinko gaming machine P counts a predetermined number C of winning balls to “9” based on the signal of the big winning opening SW 67, the big winning opening solenoid of the driving means 70. 71 moves the opening / closing member 60 to the no-winning state CL under the control of the game control board 20.

  At this time, as shown in FIGS. 9 and 4, even if the game ball B is placed on the guide surface portion 61 of the opening / closing member 60 and is positioned immediately before winning the winning prize opening 65, the guide surface portion 61 is still in the entrance hole. Since the game ball B placed on the guide surface portion 61 does not have the guide surface portion 61 used as the rolling surface 61a, the game ball B placed on the guide surface portion 61 disappears. The player immediately falls downward from the entrance 55 without winning. Therefore, even if the game ball B is placed on the guide surface portion 61 immediately before winning the prize winning opening 65, if the guide surface portion 61 moves, the game ball B is immediately won't win the prize winning opening 65. Since it falls, it is possible to stabilize the number of winning prizes to the big winning opening 65.

  In addition, the detection of the game ball B by the big prize opening SW as a detection means that triggers the movement from the prize winning state OP to the no prize winning state CL is a frame in which the big prize opening SW itself protrudes forward from the game board 1. It is arranged in the opening part 66 of the big prize opening 65 arranged on the left frame part 51 side of the body part 50 on the side where the guide surface part 61 is lowered.

  Therefore, in the big prize opening device 40 of the embodiment, it is possible to quickly detect the prize winning to the big prize opening 65 and to stabilize the number of winning prizes.

Thus, the cam frame 77 of the driving means 70 is connected so as to be in the winning state OP.

  Therefore, when the opening / closing member 60 moves the guide surface portion 61 from the non-winning state CL to the winable state OP, even if the game ball B is located in the entrance 55, the game surface B is moved by the guide surface portion 61. It can be prevented from hitting the glass frame 12 in front of the game board 1, and abnormal noise is hardly generated.

  If the above points are not taken into account, the opening / closing member 60 stores the guide surface portion 61 on the rear frame portion 54 side on the game board 1 side when placed in the no-winning state CL, and when placed in the winning-open state OP, The guide surface portion 61 may be extended forward. In this case, the guide surface portion 61 may be drawn out to the vicinity of the middle of the entrance 55 in the front-rear direction, and the guide surface portion 61 at that time may be a flat plate shape in the front-rear direction, and gaps HF and HB are provided in the front-rear direction.
