It is set so that the number of game balls that roll on the upper left guide part 42 and reach the left flow area R2 is larger than the game balls that reach the left.

  More specifically, the game ball shot from the entrance 12K is guided obliquely upward to the right by the arcuate guide portion 12D from the entrance 12K by bending the flexible regulating plate 12L toward the ball introduction area R5. Here, if the launching speed of the game ball is slow (weak), it is bounced by the flexible restricting plate 12L and cannot enter the ball introduction area R5. Therefore, the game ball is restricted from flowing down substantially vertically from the entrance 12K. In general, when a stable game is performed, a ball is introduced because a stable launch cannot be performed by a launch of strength that is not received by the upper left guide part 42 from the ball introduction area R5 and immediately flows down to the left flow area R2. The game ball will be launched around the obstacle nail 17 provided in the upper part of the area R5 (specifically, the obstacle nail 17 disposed on the side of the straight part 42A and the first arc part 42B). More game balls are received by the upper left guide part 42 and reach the left flow area R2 than are game balls that are not received by the guide part 42 and reach the left flow area R2.

  The game ball received in the ball introduction area R5 is directed to the straight portion 42A or the first arc portion 42B by the flow velocity, and collides with the obstacle nail 17 disposed along the flange portion 47F before them to guide the upper left. Guided to the part 42 or passes between the obstacle nails 17 and directly collides with the upper left guide part 42 and rolls on the upper left guide part 42 to reach the left flow area R2. . Then, some of these game balls reach the left flow area R <b> 2 without rolling the upper left guide part 42 at an angle at which the game ball collides with the obstacle nail 17.

  As shown in FIG. 5, a group of obstacle nails 17 is planted along the outer edge of the flange portion 47F at the upper end of the left-side flow area R2, and the obstacle nail 17 positioned at the top of the group of obstacle nails 17F. Is a specific nail 17K. The game ball that has flowed into the left flow area R2 is located between the first rail 12A and the failure nail 17 group, and between the failure nail 17 group and the lower bulging portion 44A, with the specific nail 17K as a boundary. To the inner flow path. Further, the specific nail 17K is arranged slightly below the step reference line K2, and the game ball flowing down from the step inclined portion 43A flows down directly to the outer channel or the inner channel, or the specific nail 17K is It gives up and branches down into an outer channel or an inner channel. 5 and 6, the head portion 17H of the obstacle nail 17 is indicated by a solid line, and the shaft portion 17S is indicated by a broken line.

  Further, the step inclined portion 43 </ b> A is disposed at a position facing the plate support portion 50. Specifically, the plate support portion 50 includes a base member 51 and a support member 52 that supports the flexible regulating plate 12L. The base member 51 has a substantially rectangular planar shape and is fixed to the game board 11 with screws. A cylindrical portion 51J protruding forward is provided at a position near the lower end of the base member 51, and is engaged with the engaging portion 52J of the support member 52 so that the support member 52 can swing relative to the base member 51. Has been.

  On the support member 52, a plate support piece 52A and a hook portion 52B protrude from the engaging portion 52J. The plate support piece 52A and the hook portion 52B are inclined upwards along an imaginary arc formed by extending the first rail 12A, and the plate support piece 52A is outside the side surface of the first rail 12A on the game area R1 side. While being disposed and extending relatively long, the hook portion 52B is disposed on the inner side of the side surface on the game area R1 side of the first rail 12A and extends relatively short, and then is bent toward the plate support piece 52A. The lower portion of the flexible regulating plate 12L is locked to the L-shaped groove portion between the plate supporting piece 52A and the hook portion 52B, and the flexible regulating plate 12L extending from the tip of the plate supporting piece 52A. The upper part is supported flexibly.

  With these configurations, of the plate support portion 50, the hook portion 52B is disposed so as to face the upper end portion of the lower bulging portion 44A, while the plate support piece 52A extending upward from the hook portion 52B is a step inclined portion. It is arranged so as to face 43A. A narrowed portion S4 is formed between the plate support portion 50 and the upper end portion of the lower bulging portion 44A, and an extension portion is provided between the plate support piece 52A extending above the hook portion 52B and the step inclined portion 43A. S3 is formed. The throttling portion S4 and the expansion portion S3 are both nail-free regions that do not have the obstacle nail 17, and can suppress the clogging of the game balls heading toward the left-flow area R2. Moreover, since the obstacle nail 17 is not provided, the game ball has a high degree of freedom in the flow-down direction, and any flow-down mode can be achieved by contact during flow-down. Further, the expansion portion S3 has a width of 3 or more game balls and less than 4 balls at the widest portion, whereas the aperture portion S4 has a width of 2 or more game balls and less than 3 balls. Therefore, the flow velocity of the game ball that has entered the left flow area R2 can be reduced at the throttle portion S4, and the load on the specific nail 17K when the game ball collides with the specific nail 17K can be reduced.

  This completes the description of the configuration of the pachinko gaming machine 10. Next, the function and effect of the pachinko gaming machine 10 will be described.

  When the game ball is shot toward the left flow area R2 by the turning operation of the operation handle 28, as shown in FIG. 6, the game ball is guided obliquely upward and to the right by the arcuate guide portion 12D from the entrance 12K. Accepted in the introduction region R5. Most of the received game balls pass between the obstacle nails 17 and directly collide with the upper left guide part 42 and are received by the upper left guide part 42, or collide with the obstacle nail 17 and receive the upper left guide part. After being guided to 42 and received by the upper left guide part 42, it rolls on the upper left guide part 42 and heads for the left flow area R2.

  By the way, conventionally, a game ball that rolls on the protruding wall in the game area and flows down to the left-side down area has a high flow-down speed, and a large load is applied to game parts such as obstacle nails provided in the left-side down area. On the other hand, in the present embodiment, the stalling portion 43 is provided between the second arc portion 42C and the lower bulging portion 44A, so that the flow down speed that rolls on the upper left guide portion 42 inclined downwardly to the left is obtained. A game ball in a relatively fast state can be made to collide with the stepped inclined portion 43A of the stalling portion 43 to be stalled. Thereby, it is possible to suppress the flow speed of the game ball flowing down to the left flow area R2, and to reduce the load applied to the specific nail 17K.

  Further, in the present embodiment, the narrowed portion S4 narrower than the expanded portion S3 is provided at the upper end portion of the left flow area R2, so that the flow velocity of the game ball can be reduced at the narrowed portion S4. In addition to this, since the extended portion S3 is configured not to have the obstacle nail 17, it is possible to suppress the clogging of the game balls heading toward the left-side flow area R2. In addition, the degree of freedom in the flow direction of the game ball is high, and any flow mode can be achieved by contact at the time of flow or the like, so that the flow speed of the game ball is reduced when the game balls collide with each other.

  Further, in the present embodiment, the specific nail 17K positioned at the top of the obstacle nail 17 planted in the left-side flow area R2 is disposed below the step reference line K2, so that the game ball can be directly Since it flows down to the road or the inner flow path, or the specific nail 17K is given up and branched into the outer flow path or the inner flow path, the load applied to the specific nail 17K can be reduced.

  Thus, according to the present embodiment, the flow velocity of the game ball flowing from the upper left guide portion 42 to the left flow area R2 can be stalled by the stall portion 43, and the upper end portion of the left flow area R2 ( Since the flow-down speed of the game ball can be reduced by the throttle unit S4), it is possible to reduce the load of the game parts in the left-hand flow area R2.

  Further, in the present embodiment, the portion that has conventionally been dented by bulging the upper left part of the projecting wall in the game area toward the display opening side is bulged toward the guide rail 12, so that the display opening 11H has been made larger than before. It becomes possible to take large. Thereby, it is possible to cope with an increase in the size of the display screen 30G, and it is possible to increase the degree of freedom in arranging the movable accessory.

  Furthermore, since the first and second hollow portions 46A and 46B are provided between the straight portion 42A and the first arc portion 42B and between the first arc portion 42B and the second arc portion 42C, the upper left guide is provided. The flow speed of the game ball flowing down the portion 42 can be reduced or accelerated. Thereby, it becomes possible to make the game ball flowing down the upper left guide part 42 into a flow-down mode with high preference.
