Further, the slant wall 128 is configured to prevent the pachinko ball from moving upstream. Specifically, the inclined wall 128 is provided above the outer edge of the detection unit 33 so that the inner surface faces the detection unit 33 (specifically, the inner side of the detection hole H). For this reason, when the pachinko sphere PB that has flowed into the evacuation passage 127 hits the inclined wall 128, or other pachinko spheres that have flowed down from the second passage 125 contact the pachinko sphere PB that has hit the inclined wall 128. At this time, a reaction force toward the detection unit 33 (inside the opening of the detection hole 33H) acts on the pachinko sphere PB (indicated by an arrow F in FIG. 7B), and the pachinko sphere PB is detected by the detection unit. 33 (detection hole 33H) is easily guided. In other words, by forming the inclined wall 128 to be inclined so that a reaction force toward the detecting portion 33 (detection hole 33H) acts on the pachinko ball PBa that has come into contact, the occurrence of ball clogging in the retreat passage portion 127 is prevented. It is preventing.

  Further, as shown in FIG. 7B, the retracting passage 127 is provided so that the inclined wall 128 and the rear edge (opening edge) 33a of the detection unit 33 in the normal winning detection sensor SE1 face each other vertically. In the state where the pachinko ball PB is in contact with the rear edge 33a of the detection unit 33 and the inclined wall 128, the center of gravity (that is, the center) G of the pachinko ball is located inside the opening edge of the detection hole 33H. It is configured to do. That is, the longitudinal dimension from the opening edge of the detection hole 33H formed by the rear edge portion 33a of the detection portion 33 to the inclined wall 128 is set to be in a range equal to or less than the radius of the pachinko sphere. For this reason, the gravity acting on the pachinko sphere PB is directed to the inside of the detection hole 33H, so that the pachinko sphere does not stop in contact with the rear edge portion 33a of the detection portion 33 and the inclined wall 128. .

  As shown in FIG. 6 (b), the retracting passage portion 127 defines the inclined wall 128 that defines the rear side of the retracting passage portion 127 and the inclined wall 128 that defines the front side of the retracting passage portion 127. The passage width (front-rear dimension) L1 between the first and second walls 124 and 125 is slightly larger than the diameter of the pachinko ball PB in the front-rear direction in the first passage 124 and the second passage 125. In comparison with the diameter of the pachinko sphere. In other words, the retreat passage portion 127 can retreat only a part of the pachinko balls that are in contact with the inclined wall 128 in the retraction passage portion 127 to the rear side from the first passage portion 124 and the second passage portion 125. In addition, the pachinko sphere cannot be positioned behind the first passage portion 124 and the second passage portion 125, so that the first passage portion 124 and the second passage portion 125 with respect to the pachinko sphere. It is configured so that pachinko spheres flowing down are in contact. Thereby, even if the pachinko ball stays in the retracting passage portion 127 in contact with the inclined wall 128, the pachinko ball stays in the retracting passage portion 127 (ball clogging) by contact with the subsequent pachinko ball. To get. Further, in the retracting passage portion 127, the passage width (front-rear dimension) L1 between the inclined wall 128 and the opposing wall is equal to or larger than the diameter of the pachinko sphere and less than twice the diameter of the pachinko sphere. Accordingly, it is possible to prevent a problem that a plurality of pachinko balls are held between the inclined wall 128 and the wall facing the inclined passage 128 in a state in which the plurality of pachinko balls are arranged in the front-rear direction in the retreat passage portion 127.

  An opening portion 129 that penetrates the discharge passage forming member 100 is formed below the inclined wall 128 in the discharge passage forming member 100, and the downstream end portion of the retracting passage portion 127 and the outside of the passage through the opening portion 129. It is configured to communicate. The opening 129 is formed so that the vertical dimension is smaller than the diameter of the pachinko sphere (indicated by symbol PB in FIG. 7B), and the pachinko sphere in the retracting passage 127 passes through the opening 129. While not discharging to the outside, an operation tool or the like is inserted through the opening 129 to remove foreign matter around the detection portion 33 of the normal winning detection sensor SE1 or the retreat passage portion 127, or to eliminate the clogging of the ball.
