  Next, as shown in FIG. 8, the second area 56 is an area included in the first area 55, and includes the vertical line L <b> 1 and the first and second arc lines L <b> 3 and L <b> 4 and the axis of the opening / closing member 42. This is an area surrounded by a 45 degree line L5 passing through m. The distribution adjustment nail 10 </ b> A is disposed in the second region 56. Furthermore, the distribution adjusting nail 10A is disposed in the vicinity of the center n of the vertical line L1 and the second vertical line L6 passing through the tip of the opening / closing member 42 at the open position.

  The distribution adjusting nail 10A is also a position near the bisecting line L7 that bisects the angle formed by the vertical line L1 and the 45-degree line L5, and is between the ball receiving port 40 and the second vertical line L6. It is also a position in the vicinity of the middle and a height position substantially the same as the upper end of the ball receiving port 40. The distribution adjusting nail 10 </ b> A may be arranged at an arbitrary position in the first region 55 or the second region 56 in addition to the above arrangement.

  The distribution device 16 is configured to be able to guide the game ball B received from the ball receiving port 40 by hitting the distribution adjusting nail 10A to the second ball distribution port 41B without contacting the opening / closing member 42. Therefore, the game ball B that hits the distribution adjusting nail 10A and bounces to the right can directly ride on the stage portion 44e. The stage portion 44e extends to the vicinity of the ball receiving port 40, and the game ball B is connected to the stage portion. If it gets on 44e, it will be guided to the 2nd ball distribution mouth 41B.

  Here, by arranging the distribution adjustment nail 10A in the first region 55, the distribution adjustment nail 10A and the opening / closing member 42 are prevented from interfering with each other, and hit the distribution adjustment nail 10A and bounced to the right. The game ball B can be directly placed on the stage portion 44e through the distribution adjusting nail 10A, between the vicinity of the upper end of the ball receiving member 44 and the frame-like portion 14a of the center accessory 14. Furthermore, by arranging the distribution adjusting nail 10A in the second region 56, it is possible to increase the possibility that the game ball B is directly placed on the stage portion 44e as compared with the case where it is arranged outside the second region 56.

  The distribution adjusting nail 10A can adjust the distribution rate by which the game ball B is alternatively distributed to either the first or second ball distribution port 41A or 41B by adjusting the inclination thereof. When it is realized that the game ball B enters the second ball distribution opening 41B mainly by directly riding on the stage portion 44e, the game ball B is moved to the second ball distribution opening as the distribution adjustment nail 10A is tilted to the right side. The rate of entering 41B increases, and the tilt of the distribution adjustment nail 10A to the left increases the rate of game ball B entering the first ball distribution port 41A.

  Further, the distribution adjusting nail 10A can adjust the entrance rate of the game ball B into the ball receiving port 40 by adjusting the inclination thereof. The game ball B launched on the game board 4 hits the sorting adjustment nail 10A from the left side (that is, jumps to the left side) rather than hitting the sorting adjustment nail 10A from the right side (that is, jumps to the left side). In many cases, the entrance rate increases as the distribution adjustment nail 10A is tilted to the right, and the entrance rate decreases as the distribution adjustment nail 10A is tilted to the left.

  The first and second ball guiding passages 46A and 46B extend along the left and lower portions of the center accessory 14 from the first and second ball distribution ports 41A and 41B, respectively. It is arranged to extend to the lottery device 17). The first and second ball guiding passages 46A and 46B are provided with first and second ball sorting ports SW41Aa and 41Ba for detecting the game balls B that have entered the first and second ball sorting ports 41A and 41B. Yes. The first and second ball guiding passages 46A and 46B are used to guide the game balls B that have entered the first and second ball distribution ports 41A and 41B so as not to flow back to the lower part of the center accessory 14, respectively. The height position becomes lower on the downstream side.

  As shown in FIGS. 1, 2, and 9 to 11, the mechanical lottery device 17 is attached to the sorting device 16 and is provided inside the lower part of the center accessory 14. The mechanical lottery device 17 performs lottery by the game balls B being guided in the first and second ball guide passages 46A and 46B, respectively, and when the game balls B are guided in the second ball guide passage 46B, There is a higher possibility of deriving a lottery result that is advantageous to the player than when guided by the one-ball guide passage 46A.

  This mechanical lottery device 17 has a specific winning opening 60 for generating a big hit gaming state by winning a game ball B. When the game ball B guided by the first and second ball guide passages 46A and 46B is introduced into the mechanical lottery device 17, and the game ball B is introduced from the second ball guide passage 46B, the first is selected. The probability of winning in the specific winning opening 60 is higher than when introduced from the ball guide passage 46A (for example, the probability of winning in the specific winning opening 60 in the former case is halved and specified in the latter case) The probability of winning at the winning opening 60 is 1/8).

  A specific example of the mechanical lottery device 17 will be described. The lottery rotator 60 is provided so as to rotate around the vertical axis, and its bottom surface and outer peripheral surface are slidable on the bottom wall and outer peripheral wall of the rotator tray 61. Abut. In the outer peripheral side portion of the lottery rotator 60, in cooperation with the rotator tray 61, there are one hit ball mounting portion 60a and seven off-ball mounting portions 60b each capable of mounting and holding the game balls B. A total of eight ball mounting portions 60a and 60b are formed so as to be partitioned at equal intervals in the circumferential direction.

  In the lottery rotator 60, the bottom of each of the ball mounting portions 60a and 60b is formed to have a lower height toward the outside in the radial direction, and an opening 60c is formed at the bottom of the hitting ball mounting portion 60a. A special winning hole 63 is formed at the bottom of the front portion of the rotating body receiving tray 61 so as to be positioned below the outer peripheral side portion of the lottery rotating body 60, and the receiving tray protrusion that protrudes forward from the front portion of the rotating body receiving tray 61. A non-specific winning opening 64 is formed at the bottom of 61a.

  The lottery rotator 60 has a hit guide path 60d inclined downward from the center of the lottery rotor 60 toward the hit ball mounting portion 60a, and one off-ball mount on the opposite side of the hit ball mounting portion 60a from the center. A detachment guide path 60e that is inclined downward toward the mounting portion 60b is formed. The lottery rotary motor 62 is driven so that the lottery rotary body 60 rotates regularly. For this reason, the lottery rotary motor 62 is disposed on the lower side of the rotary body tray 61, and its output shaft 62a is The rotating body tray 61 is inserted and fixedly fitted to the center of the lottery rotating body 60.

  Is the game ball B introduced from the first ball guiding passage 46A transferred directly from any fixed position to any one of the eight ball mounting portions 60a and 60b and transferred to the hit ball mounting portion 60a? Whether it is transferred to the off-sphere mounting portion 60b is determined by the rotational position of the rotating body receiving tray 61, and is transferred to the hitting ball mounting portion 60a with a probability of 1/8. In addition, the game ball B introduced from the second ball guide passage 46B is first dropped from the fixed position to the boundary between the hit guide path 60d and the release guide path 60e, and from there, the rotational position of the rotating body tray 61 is related. Instead, it is transferred to either the hit ball mounting part 60a or one outlier ball mounting part 60b, and transferred to the hit ball mounting part 60a with a probability of 1/2.

  The game ball B placed on the winning ball placement portion 60a passes through the opening 60c and wins the special winning opening 63 at a position where the hit ball placement portion 60a coincides with the specific winning opening 63, and then comes off. The game ball B placed on the ball placing portion 60b moves to the saucer projecting portion 61a at the position where the off-ball placing portion 60b coincides with the saucer projecting portion 61a and wins a non-specific winning opening 64. The game balls B that have won the winning openings 63 and 64 are discharged to the outside through the ball discharge paths 65 and 66, respectively. The game ball B that has won the specific winning opening 63 is detected by the specific winning opening SW67.

  By the way, as shown in FIG. 12, the main control device 21 (game control board 22) performs random number acquisition means 21a, random number determination means 21b, distribution opening / closing control means 21c, opening / closing operation pattern storage means 21d, winning prize opening / closing control. Means 21e are configured.

  The random number obtaining unit 21a obtains a random value when the game ball B is won at the start port 11, and the random number judging unit 21b judges the type of the symbol based on the random value obtained by the random number obtaining unit 21a. . The type of symbol determined by the random number determination means 21b is displayed on the symbol display 19a after the change. The distribution opening / closing control means 21c is included in the distribution apparatus 16, and when the specific symbol determined by the random number determination means 21b is displayed on the symbol display 19a, the opening / closing member 42 of the distribution apparatus 16 is provided. The distribution opening / closing SOL 55 is controlled so as to be opened / closed.

  Here, as shown in FIG. 13, the random number determination means 21b uses any one of a plurality of types of specific symbols (a first specific symbol, a second specific symbol, a third specific symbol,...) As a specific symbol. The opening / closing operation pattern storage means 21d stores the opening / closing operation patterns of the opening / closing members 42 that are different depending on the type of the specific symbol. The sorting opening / closing SOL 55 is controlled by the sorting opening / closing control means 21c so as to obtain an opening / closing operation pattern corresponding to the type of the specific symbol displayed. The big prize opening / closing control means 21e sets the big prize opening SOL12d so that a big hit gaming state in which the big prize opening 12a opens and closes over a plurality of rounds when the game ball B is detected by the specific prize opening SW67 is generated. Control.

The operation and effect of the sorting device 16 of the pachinko gaming machine 1 will be described.
Normally, the player operates the launch handle 7 and launches the game ball B aiming at the start port 11 to play a game. When the game ball B wins the start opening 11, a lottery can be received, and when the winning is won by the lottery (when a specific symbol is displayed on the symbol display 19 a), the sorting device 16 is activated to open and close the opening / closing member 42. Opens and closes the ball receiving port 40 one or more times in a relatively short time.

  When the ball receiving port 40 is opened, the game balls B received from the ball receiving port 40 by hitting the distribution adjusting nail 10A are alternatively distributed to either the first or second ball distributing port 41A or 41B. Thus, the game ball B can be guided to the second ball distribution opening 41 </ b> B without contacting the opening / closing member 42. Here, the game hall side selectively distributes the game ball B to one of the first and second ball distribution ports 41A and 41B by adjusting the inclination of the distribution adjustment nail 10A as described above. The distribution rate can be adjusted. When the game ball B enters the first ball distribution slot 41A, a jackpot gaming state occurs with a probability of 1/8, and when the game ball B enters the second ball distribution slot 41B, 1/2 A jackpot gaming state occurs with a probability of.

  For the game balls B that have entered the first and second ball distribution openings 41A and 41B (that is, guided by the first and second ball guide passages 46A and 46B, respectively), the first and second balls Since it can be detected by the distribution openings SW46Aa and 46Ba, when this detection is performed, an effect is executed using the image display 15 or the like. In this case, when the game ball B enters the second ball distribution opening 41B, It is possible to execute a game effect that can be expected to generate a big hit gaming state as compared with the case of entering the one-ball distribution slot 41A.

  In particular, the distribution adjusting nail 10A is provided outside the ball receiving port 40 and in the vicinity of the ball receiving port 40 so as not to interfere with the opening / closing member 42. The distribution adjusting nail 10A hits the distribution adjusting nail 10A and is received from the ball receiving port 40. The game balls B can be alternatively distributed to one of the first and second ball distribution ports 41A and 41B, and the distribution ratio can be adjusted. Thereby, it is possible to adjust the gaming performance (for example, the expected average number of occurrences of the big hit gaming state with respect to the total number of game balls B fired on the gaming board 4), and therefore the adjustment range of the gaming performance And the distribution rate can be stabilized (stablely set to a desired distribution rate).

  Since the distribution adjusting nail 10A can adjust the entrance rate of the game ball B to the ball receiving port 40 together with the allocation rate, both the allocation rate and the entrance rate are applied to the distribution adjusting nail 10A. Can be provided with an adjustable function, which is convenient in adjusting game performance.

  Since the distribution adjusting nail 10A is disposed in the first region 55 surrounded by the vertical line L1, the horizontal line L2, and the first and second arc lines L3 and L4, the ball receiving port 40 hits the distribution adjusting nail 10A. It is also possible to guide the game ball B received from the second ball distribution port 41B without contacting the opening / closing member 42, and to distribute the distribution adjustment nail 10A to the reception port 40 together with the distribution rate. It is possible to make the entrance rate of the game balls B adjustable, and it is possible to secure the function of the sorting adjustment nail capable of adjusting the sorting rate.

  Moreover, since the distribution adjusting nail 10A is disposed in the second region 52 surrounded by the vertical line L1, the first and second arc lines L3, L4, and the 45 degree line L5, the distribution ratio can be adjusted. The distribution adjusting nail 10A is more reliably secured, and the distribution adjusting nail 10A is disposed in the vicinity of the center n between the vertical line L1 and the second vertical line L6. The distribution adjusting nail 10A can be provided so that the function of the adjustable distribution adjusting nail can be exhibited most.

  When the game balls B are guided in the first and second ball guide passages 46A and 46B, respectively, a mechanical lottery device 17 for lottery is attached, and the game balls B are guided in the second ball guide passage 46B. Since there is a higher possibility of deriving a lottery result that is advantageous to the player than when guided by the first ball guide passage 46A, it is possible to improve the game performance. In addition, since the distribution ratio can be stably set to a desired distribution ratio, the average number of occurrences of the predicted jackpot gaming state is stabilized with respect to the total number of game balls B fired on the game board 4. Thus, the desired gaming performance of the pachinko gaming machine 1 can be exhibited.

  Since the mechanical lottery device 17 is a lottery device having a specific winning opening 63 that generates a big hit gaming state by winning the game ball B, unlike a random number lottery, the player performs a lottery operation by the mechanical lottery device 17. You can see and enjoy it, and you can further enhance your gameplay.

  In addition, various modifications can be added without departing from the spirit of the present invention. For example, when the game ball B is introduced into the mechanical lottery device 17 from the first ball guide passage 46A, the probability that the game ball B is won through the second ball guide passage 46B is higher than the case where the game ball B is introduced from the second ball guide passage 46B. You may comprise.
