By extending downward from the lower surface of one end portion (here, the left end portion), the guide wall portion 82 provided below the gate portion 81 and the other end portion in the left-right direction of the gate portion 81 (here, A ball intrusion prevention wall portion 83 provided below the gate portion 81 is provided by extending downward from the lower surface of the right end portion).

  As shown in FIGS. 3 and 5, the gate portion 81 includes a gate-shaped frame portion 86 formed integrally with the base portion 80, and a gate switch 85 having a passage port 85 a through which a game ball can pass. The gate portion 81 is surrounded by the frame portion 86 and the base portion 80, thereby forming a rectangular hole 87 penetrating vertically. The gate switch 85 is inserted into the frame portion 86 from the rear of the base portion 80 through a hole (not shown) formed in the base portion 80, and the passage port 85 a is disposed in the hole 87. Therefore, the game ball passes up and down the gate portion 81 by passing through the passage opening 85a. The gate switch 85 has a portion that protrudes behind the base portion 80, but this portion is not shown. The gate switch 85 is configured to detect passage of the game ball through the passage opening 85a and transmit the detection signal to the main control board.

  As shown in FIG. 2, the guide wall portion 82 has a wall shape that is bent in the middle while extending obliquely downward to the right as a whole from the lower surface of the left end portion of the gate portion 81. A game ball guiding passage 84 (a portion marked with light ink in FIG. 2) is formed to be guided obliquely downward. Specifically, the guide wall portion 82 includes a first wall portion 82a extending obliquely downward to the right from the lower surface of the left end portion of the gate portion 81, and a second wall portion extending obliquely downward to the left from the lower end portion of the first wall portion 82a. 82b and a third wall portion 82c extending obliquely downward to the right from the lower end portion of the second wall portion 82b. Each of the first wall portion 82a and the third wall portion 82c has a substantially arc shape that swells outward (on the opposite side to the game ball guiding passage 84 side) in a front view. In addition, since the first wall portion 82a is shorter than the third wall portion 82c, the game ball that has passed through the gate portion 81 immediately reaches the third wall portion 82c and follows the third wall portion 82c. Will flow down diagonally. The third wall portion 82c extends to the right side of a vertical line passing through the center in the left-right direction of the gate portion 81 (a line indicated by a one-dot chain line A in FIG. 2; hereinafter referred to as “vertical line A”).

  The ball intrusion prevention wall portion 83 has a wall shape that extends in a diagonally downward left direction from the lower surface of the right end portion of the gate portion 81 to be shorter than the guide wall portion 82, and the guide wall portion 82 sandwiches the game ball guide passage 84. It is provided on the opposite side. The distance between the lower end 83a of the ball intrusion prevention wall 83 and the lower end of the first wall 82a (that is, the boundary between the first wall 82a and the second wall 82b) 82d is determined by the diameter of the game ball. The space between the lower end 83a and the lower end 82e of the guide wall 82 is slightly larger than the diameter of the game ball. A portion between the lower end portion 83 a of the ball intrusion prevention wall portion 83 and the lower end portion 82 e of the guide wall portion 82, that is, a portion indicated by a two-dot chain line in FIG. 2 is an outlet 84 a of the game ball guiding passage 84. That is, the game ball that has passed through the gate portion 81 passes between the lower end portion 82d and the lower end portion 83a, is guided to the third wall portion 82c, and guides the game ball from between the lower end portion 82e and the lower end portion 83a. Go out of passage 84. The game ball guiding passage 84 can also be said to be a portion surrounded by the guide wall portion 82 and the ball intrusion prevention wall portion 83.

  Further, the surface 82f of the second wall portion 82b on the side of the game ball guiding passage 84 approaches the outlet 84a of the game ball guiding passage 84 from the vertical direction (the direction indicated by the one-dot chain line B in FIG. 2) with respect to the lower end. Thus, the inclined surface is inclined. Since the surface 82f serves as a backflow prevention surface that prevents the game ball being guided to the third wall portion 82c from flowing back into the gate portion 81, the surface 82f is hereinafter referred to as a backflow prevention surface 82f. In the present embodiment, the backflow prevention surface 82f is a flat surface, but may be a curved surface such as an arc surface.

  The operation and effect of the pass gate device 8 configured as described above will be described with reference to FIG. As shown in FIG. 6A, when the game ball B1 passes through the gate portion 81 of the passing gate device 8, it is guided to the guide wall portion 82 and heads toward the outlet 84a. That is, the game ball B1 is guided obliquely downward. In the middle of this guidance, it is assumed that the game ball B2 that has passed through the gate portion 81 and exited from the game ball guide passage 84 hits the game nail 6 and bounces as shown by the arrow, and collides with the game ball B1. Then, the game ball B1 flows backward in an obliquely upward direction. However, in the middle of this backflow, the backflow prevention surface 82f is provided so as to be inclined so that the upper end approaches the outlet 84a from the vertical direction with respect to the lower end, that is, it faces obliquely downward so as to approach the outlet 84a direction. Therefore, the backflow prevention surface 82f faces the backflow direction of the game ball B1, and the backflow of the game ball B1 is blocked by the backflow prevention surface 82f as shown in FIG. 6B. Therefore, the game ball B1 is prevented from returning to the gate portion 81 and being read twice.

  Note that the intrusion of the game ball B2 into the game ball guiding passage 84 is limited to the intrusion from the outlet 84a by the ball intrusion prevention wall portion 83, so that the possibility of the invasion of the game ball B2 into the game ball guiding passage 84 is reduced. The Therefore, the possibility that the game ball B1 is read twice is also reduced by the ball intrusion prevention wall portion 83.

  Further, the lower portion of the guide wall portion 82 (that is, the third wall portion 82c) extends from the left end portion of the gate portion 81 to the right side of the vertical line A (see FIG. 2) passing through the center in the left-right direction of the gate portion 81. ing. That is, since it extends so as to cross the vertical line A, the entry of the game ball B <b> 2 into the game ball guide passage 84 from directly below is prevented by the guide wall portion 82. Therefore, the possibility that the game ball B1 that has passed through the gate portion 81 is pushed back by the game ball B2 and read twice is reduced. In addition, in this embodiment, although the guide wall part 82 has crossed the perpendicular line A diagonally, you may cross | intersect just beside.

  Next, a second embodiment of the present invention will be described with reference to FIGS. In addition, about the component corresponding to each component of 1st Embodiment, the description is abbreviate | omitted using the same code | symbol. The second embodiment has the same configuration as the first embodiment except for the shape of the guide wall portion 82. In the first embodiment, the backflow prevention surface 82f is provided in the intermediate portion (in the length direction) of the guide wall portion 82, but in the second embodiment, it is provided in the upper portion of the guide wall portion 82.

  The passing gate device 8 according to the second embodiment includes a base portion 80, a gate portion 81, a guide wall portion 82 extending downward from the lower surface of the left end portion of the gate portion 81, and the lower surface of the right end portion of the gate portion 81. And a ball intrusion prevention wall portion 83 extending downward from the bottom. A game ball guide passage 84 is formed in the lower region of the gate portion 81 by the guide wall portion 82, and the ball intrusion prevention wall portion 83 is provided on the opposite side of the guide wall portion 82 with the game ball guide passage 84 interposed therebetween. Yes.

  In the second embodiment, the guide wall portion 82 has a wall shape bent in a substantially square shape. Specifically, the guide wall portion 82 includes a first wall portion 82a extending in a diagonally downward left direction from the lower surface of the left end portion of the gate portion 81, and a second wall portion extending in a diagonally downward right direction from the lower end portion of the first wall portion 82a. 82b, and the second wall portion 82b has a substantially arc shape that swells outward (on the opposite side to the game ball guiding passage 84 side) in a front view. The first wall portion 82a is shorter than the second wall portion 82b, and the second wall portion 82b extends to the right side of the vertical line A so as to cross the vertical line A diagonally.

  The ball intrusion prevention wall portion 83 has a wall shape extending from the lower surface of the right end portion of the gate portion 81 obliquely to the left and shorter than the guide wall portion 82, and the lower end portion 83a of the ball intrusion prevention wall portion 83 and the guide wall portion. The distance between the lower end portion 82e of the game ball 82 and the lower end portion 82e is slightly larger than the diameter of the game ball, and a space between the lower end portion 83a and the lower end portion 82e serves as the outlet 84a of the game ball guiding passage 84.

  The surface 82f of the first wall portion 82a of the guide wall portion 82a on the side of the game ball guiding passage 84 has an upper end that is perpendicular to the lower end (the direction indicated by the alternate long and short dash line B in FIG. 7). The inclined surface is inclined so as to approach 84a. Since the surface 82f serves as a backflow prevention surface, it is hereinafter referred to as a backflow prevention surface 82f. In this embodiment, the backflow prevention surface 82f is a flat surface, but may be a curved surface such as an arc surface.

  The operation and effect of the pass gate device 8 of the second embodiment will be described with reference to FIG. As shown in FIG. 8A, when the game ball B1 passes through the gate portion 81 of the passing gate device 8, it is guided to the guide wall portion 82 and heads toward the outlet 84a. In the middle of this guidance, it is assumed that the game ball B2 that has passed through the gate portion 81 and exited from the game ball guide passage 84 hits the game nail 6 and bounces as shown by the arrow, and collides with the game ball B1. Then, the game ball B1 flows backward obliquely upward, but the backflow prevention surface 82f is provided so as to face the reverse flow direction, so that the reverse flow of the game ball B1 flows backward as shown in FIG. It is blocked by the prevention surface 82f. Therefore, reading of the game ball B1 twice is prevented.

  Similarly to the first embodiment, the ball intrusion prevention wall 83 also reduces the risk of the game ball B2 being invaded, so that the possibility of the game ball B1 being read twice is reduced.

  Further, as in the first embodiment, the entry of the game ball B2 from directly below is prevented by the guide wall portion 82, and the game ball B1 that has passed through the gate portion 81 is pushed back by the game ball B2 and read twice. The risk of being reduced is reduced.

  In order to further reduce the possibility of reading twice, it is preferable to provide the ball intrusion prevention wall portion 83, but of course, the ball intrusion prevention wall portion 83 may not be provided. FIG. 9 shows a modification in which the ball intrusion prevention wall portion 83 is not provided in the first embodiment. In this case, the portion marked with light ink in FIG. 9 becomes a game ball guiding passage 84 formed by the guide wall portion 82, and the lower end portion 82e of the guide wall portion 82 and the right end portion of the gate portion 81 (the guide wall portion 82 is provided). The portion that is connected to the opposite end to the side that is provided, that is, the portion indicated by the two-dot chain line in FIG. 9 is the outlet 84a.

  Also, the shape of the guide wall portion 82 can be changed as appropriate. For example, the backflow prevention surface 82f is formed by bulging or branching a part of the guide wall portion 82 toward the game ball guiding passage 84 instead of bending. It is good as well. Further, the extending length of the guide wall portion 82 can be shortened so that the guide wall portion 82 does not cross the vertical line A.

  Further, in each of the above embodiments, the backflow preventing surface 82f is an inclined surface inclined so as to approach the outlet 84a of the game ball guiding passage 84 from the vertical direction with respect to the lower end of the backflow prevention surface 82f. The game ball is prevented from flowing backward (that is, facing the backward direction so as to face the backward flow direction). However, if the gaming ball can be prevented from flowing backward, the back flow preventing surface 82f is placed with the upper end at the lower end. On the other hand, the shape of the backflow preventing surface 82f can be changed as appropriate, such as a surface that is arranged in the vertical direction (that is, a vertical surface).

  Further, the upper ends of the guide wall portion 82 and the ball intrusion prevention wall portion 83 do not necessarily need to be in contact with the gate portion 81, but between the lower surface of the gate portion 81 and the upper end of the guide wall portion 82, You may provide the clearance gap between the lower surface and the upper end of the ball | bowl penetration prevention wall part 83 so that a game ball may not pass.
