A sphere that flows down the upper surface of the body 17 in the other direction from the rear side to the front side is formed in a convex shape, and the sphere that flows down the upper surface of the upper sphere sorting body 17 from the front side to the rear side The trapped sphere is trapped in the concave shape of the front portion 21a, and the upper sphere sorting body 17 flows down from the rear side to the front side as the upper sphere sorting body 17 changes from the forward tilted shape to the backward tilted shape. The sphere flowing down from the rear side to the front side of the upper sphere sorting body 17 may be distributed to the left and right by the convex rear portion 21 b of the sorting protrusion 21.

  The chance that the sphere hits from both the upper sphere allocating body 17 and the lower sphere allocating body 29 and is taken into the sphere intake section 30 is reduced as compared with the best mode, but the sphere intake drive mechanism 31 is not provided, The ball-intake unit 30 can take in the balls that fall from the upper ball sorter 17 to the rear side and the balls that fall from the rear side of the lower ball sorter 29 without the ball-intake unit 30 moving in the left-right direction. If possible, if the hit ball intake portion 30 is fixedly provided over the rear side of the upper ball sorter 17 and the rear side of the lower ball sorter 29, the structure can be obtained without providing the ball intake drive mechanism 31. It will be easy.

  In the best mode, the front surface of the hit ball intake portion 30 is configured as a vertically long groove shape having an opening extending over the upper ball sorter 17 and the lower ball sorter 29, but the hit ball intake portion 30 is the upper ball sorter. 17 and the lower sphere allocating body 29 are formed in a vertically long cylindrical shape. From the upper sphere allocating body 17 to the front surface corresponding to the upper sphere allocating body 17 and the front surface corresponding to the lower sphere allocating body 29 in the cylindrical shape. You may form the through-hole which the ball | bowl discharged | emitted on the rear side or the ball | bowl discharged | emitted on the rear side from the lower ball | bowl allocating body 29 can be made into the ball-intake part 30 separately.

  The winning ball receiving portion 30 and the off-ball receiving portion 32 may be provided with their positions shifted in the front-rear direction. The winning ball receiving portion 30 may be set as a falling ball receiving portion, and the falling ball receiving portion 32 may be set as a winning ball intake portion, whereby the falling ball receiving portion may be disposed inside the winning ball receiving portion. In this case, if the lateral width of the falling ball intake portion 32 set as the hitting ball intake portion is formed wider than the horizontal width of the hitting ball intake portion 30 set as the falling ball intake portion, The ball is more easily taken into the hitting ball intake unit 30 set as the dislodged ball intake unit than the ball is separated from the ball sorter 29 and taken into the hitting ball intake unit 30 set as the ball offtake unit. The hitting ball receiving part 30 disposed inside the falling ball receiving part 32 is driven to reciprocate in the left-right direction by the ball intake driving mechanism 31, but the falling ball receiving part 32 arranged inside the hitting ball receiving part is The ball take-in drive mechanism 31 may be driven so as to reciprocate in the left-right direction.

  The opening / closing body 8 may not be provided. That is, the structure may be such that the ball enters the inner region surrounded by the front partition wall 6 from the game region 108 via the ball inlet portion 7. The lower ball distribution body 29 may be omitted.
