The present invention relates to a center decoration of a pachinko machine, and more particularly to a stage structure for dropping a ball onto a winning part for starting.
[0002]
[Prior art]
FIG. 5 shows the front of a game board 101 which is a game main body of a pachinko machine disclosed in Japanese Patent Application Laid-Open No. 9-192304, and the game board 101 is surrounded by guide rails 102 on a design board surface which is a front face of the game board 101. In the inner game area, there are provided a start winning part 103, a symbol display 104, a variable winning part 105, a general winning part 106, a windmill 107, a side lamp 108, a center decoration 109, a large number of game nails (not shown), and the like. The center decoration 109 has a see-through panel 110 inserted from the front side into an opening (not shown) formed so as to penetrate the game area of the game board 101 in the front-rear direction. The symbol display device 104 is arranged on the back side of the center decoration 109 so that a display screen can be visually recognized by a player from the front side of the game board 101 through the see-through panel 110 of the center decoration 109.
[0003]
Then, in a state where the player puts the ball in a dish device (not shown) provided on the front of the game machine frame (not shown) in which the game board 101 is stored, the player can use the handle provided on the front surface of the game machine frame. When a ball shooting operation component (not shown) such as a grip is operated, a ball shooting mechanism (not shown) provided inside the gaming machine frame fires a ball supplied from the dish apparatus toward the game area, and the game area. When the ball fired at the prize wins the start prize part 103 or the general prize part 106, a start prize sphere detector (not shown) that detects the ball that has won the start prize part 103 outputs a start prize signal to a controller (not shown). Alternatively, a general winning ball detector (not shown) that detects a ball winning the general winning component 106 outputs a general winning signal to the control device.
[0004]
When the control device inputs a start winning signal or a general winning signal, the control device detects the input of the starting winning signal or the general winning signal to which input port of the input interface of the control device, and thereby the signal input by the control device. Specifies (detects) which starting prize ball detector is the starting prize signal or which general prize ball detector is the winning signal, and the control device detects (determines) the starting prize signal as a trigger. The symbol display 104 and the variable winning parts 105 execute a game advantageous to the player. Therefore, the symbol display 104 and the variable winning part 105 are game parts that execute a game advantageous to the player when the ball is won in the starting winning part 103. In addition, a start winning part 103 and a plurality of variable winning parts 105 are provided in the game area of the game board 101 so that a ball can be won from the game area, while the symbol display 104 is provided in the game area of the game board 101. It is provided so as to be visible from the front side.
[0005]
On the other hand, the center decoration 109 will be described. The center decoration 109 includes a celestial sphere inlet 111, a warp passage 112 bypassing the periphery of the see-through panel 110, a stage 113 along the lower edge of the see-through panel 110, and a stage connection formed in the warp passage 112. Port 114, a rear ball inlet 116 formed in the lower passage 115 of the warp passage 112, a front ball outlet 118 formed in the front wall 117 of the center decoration 109 located below the warp passage 112, and a rear ball inlet 116. A communication path 119 connecting the front ball outlet 118 and the front ball outlet 118, and a distribution mechanism 120 disposed at the stage communication port 114 are provided. The distributing mechanism 120 has a plurality of ball passage holes 122 also shown in FIG. 6 on the peripheral wall of the hollow cylindrical rotary body 121 shown in FIG. 6 which is rotationally driven by a motor (not shown) provided on the back side of the center decoration 109. Have.
[0006]
Then, the sphere taken in from the celestial sphere inlet 111 flows down the warp passage 112 and becomes entangled with the rotating body 121 of the distribution mechanism 120 at the stage connection port 114. The entangled ball is taken into the inside of the rotating body 121 from the ball passing hole 122, and a certain ball is discharged from the inside of the rotating body 121 to the stage 113 via the ball passing hole 122 and the stage communication port 114 in order. A certain ball is discharged from the inside of the rotating body 121 to the lower passage 115 via the ball passage hole 122. The ball discharged to the stage 113 falls from the stage 113 in the direction of the winning prize part 103, and the ball discharged to the lower passage 115 passes from the lower passage 115 to the front ball through the back ball inlet 116 and the communication passage 119 in order. It falls from the exit 118 in the direction of the starting winning part 103. Since the front ball exit 118 is closer to the start winning part 103 than the stage 113, the ball dropped from the front ball outlet 118 is more likely to win the start winning part 103 than the ball dropped from the stage 113.
[0007]
[Problems to be solved by the invention]
However, the prior art has a structure in which the distribution mechanism 120 only distributes the ball to the stage 113 or the lower passage 115 only once. Since the distance from the start winning part 103 is larger than the distance from the starting part 103, the probability that the ball distributed to the stage 113 by the distribution mechanism 120 will win the start winning part 103 will be higher than the ball distributed to the lower passage 115 by the distribution mechanism 120. Is low, and the player is less likely to win the start winning part 103 because the ball is distributed to the stage 113 by the distribution mechanism 120.
[0008]
In view of the above, the present invention provides a center decoration of a pachinko machine capable of maintaining a player's expectation of winning a winning part with a two-stage sorting function of a ball and improving playability.
[0009]
[Means for Solving the Problems]

The ball is taken into the ball sorter from the upper stage from the game area of the game board by being placed directly above the ball, and the ball dropped from at least one specific ball sorting hole in the ball sorter is introduced into the ball. From the ball outlet via the mouth to the starting winning part directly below And the ball that has fallen from the non-specific ball distribution hole falls into the connecting portion between the ball inlet and the lower stage and falls from the connecting portion into the ball inlet or flows in the direction of the lower guide. The ball that has flowed to the lower guide falls from the lower guide to the side of the starting winning part. In other words, since the ball is formed in two stages, the ball sorting function by the ball sorting body and the ball sorting function by the connection portion between the ball inlet and the lower stage, the ball has dropped from a non-specific ball sorting hole. It is possible for the ball to fall from the ball outlet to the start winning part directly below the ball outlet through the ball inlet in the same way as a ball that has fallen from a specific ball distribution hole. It can be maintained by the player, and the game performance can be improved. Further, in the present invention, the ball distributing body has a round dish shape fixed to the upper stage, and the bottom is shaped like a mortar that gradually flows toward the center while drawing a sphere of falling spheres. If a plurality of ball distribution holes are formed at the bottom while being formed on the slope of the shape, the player can properly process the ball taken in the ball distribution body into one of the multiple ball distribution holes Can be grasped. Further, in the present invention, if a projection is provided at the center of the bottom dish in the round dish-shaped ball distributing body, the projection can be used for any one of the plurality of ball sorting holes when the ball is taken in the ball distributing body. Can be reliably captured. Further, in the present invention, a ball falling from a ball distribution hole other than at least one of the plurality of ball distribution holes collides with a connection portion between the ball inlet and the lower stage. By providing a ball distribution projection and a drop area for dropping a ball from the lower stage, it is possible to make a ball fly by the ball distribution projection and drop the ball to the ball inlet by the drop area. . Also, in the present invention, if a guide rail for guiding the ball is provided at the bottom of the communication path connecting the ball discharge port and the ball introduction port, the guide rail converts the ball to a starting winning part directly below the ball discharge port. It can fall properly toward.
