The front end portion of 43 is fitted. In addition, a spring 44 is attached to the plunger 43 at a portion located between the rotary lever 46 and the solenoid 40. The spring 44 is for pushing the plunger 43 outward when the energization of the solenoid 40 is interrupted. An engaging piece 45 is formed at the tip of the plunger 43. The engaging piece 45 engages with the rotating lever 46 when the plunger 43 is attracted by the solenoid 40, and rotates the rotating lever 46. It is what makes it work.
[0021]
The start winning device 5 configured as described above is mounted on the surface of the game board 2 by screws (not shown) inserted through mounting holes 23 drilled in two places on the side of the mounting plate 10.
[0022]
In the start winning device 5 mounted on the surface of the game board 2, when the solenoid 40 is excited and the plunger 43 is sucked, the rotating lever 46 is turned by the engagement piece 45 of the sucked plunger 43 as shown in FIG. When the engaging recesses 48a and 48b move upward, the connecting pins 31a and 31b are lifted upward. When the connecting pins 31a and 31b are lifted upward, the pair of opening and closing members 30a and 30b are opened, and the start winning device 5 is inclined, and can accept a pachinko ball as shown in FIG.
[0023]
Next, when the energization of the solenoid 40 is interrupted from the inclined state, the excitation of the solenoid 40 is released, so that the attractive force to the plunger 43 is lost, and the plunger 43 is pushed out by the spring 44. When the plunger 43 is pushed outward, as shown in FIG. 4, the rotating lever 46 rotates counterclockwise, and the engaging recesses 48a and 48b move downward, so that the connecting pins 31a and 31b move downward. When the connecting pins 31a and 31b are lowered downward, the pair of opening and closing members 30a and 30b are closed, and the start winning device 5 is in a standing state and cannot accept the pachinko balls.
[0024]
The structure and operation of the start winning device 5 according to the embodiment have been described above. However, in the start winning device 5 according to the present embodiment, as shown in FIG. 5, the tips of the pair of opening / closing members 30a and 30b in the standing state. Since the pair of opening and closing members 30a and 30b are pivotally supported so that the distance is substantially the same as the width of the switch mounting portion 11 to which the detection switch 24 is attached, as shown in FIG. Without increasing the distance between the tip of the switch 30b and the switch mounting part 11, the distance B between the end face of the switch mounting part 11 and the opening / closing members 30a, 30b in the inclined state can be sufficiently secured, and the pachinko ball can be easily Can accept.
[0025]
Further, as in the present embodiment, the pair of opening / closing members 30a, 30b is pivotally supported so that the distance between the tips of the pair of opening / closing members 30a, 30b is substantially the same as the width of the switch mounting portion 11 to which the detection switch 24 is attached. In this case, the gap inside the shaft support portion of the opening / closing members 30a and 30b is considerably larger than the diameter of the pachinko ball (however, smaller than twice the diameter of the pachinko ball), so as shown in FIG. When two pachinko balls are received simultaneously from the left and right opening / closing members 30a, 30b, the two pachinko balls may be sandwiched between the lower ends of the opening / closing members 30a, 30b, which may cause clogging. Therefore, in the start winning device 5 according to the present embodiment, as shown in FIG. 5, the pachinko balls received between the pair of opening and closing members 30a and 30b in an inclined state are guided toward the one opening and closing member 30a. When the two pachinko balls win the start winning device 5 from the left and right directions at the same time by projecting the guiding projection 21 to be projected in the vicinity of the shaft support portion of the one opening / closing member 30a, the guiding projection 21 is formed as shown in FIG. Since the pachinko balls on the projecting side have a stepped shape placed on the upper part of the pachinko balls on the side on which the guide protrusion 21 is not projecting, two pachinko balls are jammed in the opening / closing members 30a and 30b. Never become. The guide protrusion 21 may be provided in the vicinity of the shaft support portion of the other opening / closing member 30b.
[0026]
Further, as in the present embodiment, the guide protrusion 21 that guides the pachinko ball received in an inclined state between the pair of opening and closing members 30a and 30b toward the one opening and closing member 30a is supported by the shaft support portion of the one opening and closing member 30a. When projecting in the vicinity, as shown by a two-dot chain line in FIG. 6, the curved radius on the side where the guiding projection 21 is not provided across the center line of the guiding bottom surface 38 is set, and the guiding projection 21 is located across the center line. When formed with the same dimension as the curved surface radius of the provided side, the pachinko ball on the side where the guide projection 21 is projected is placed on the upper part of the pachinko ball on the side where the guide projection 21 is not projected. The lower pachinko balls are pressed in a substantially vertical direction with respect to the guide bottom surface 38 by the pressure from the upper pachinko balls, so that it is difficult for the lower pachinko balls to escape along the guide bottom surface 38. Ku, there is fear that becomes difficult to introduce into the ball inlet 13. For this reason, in the start winning device 5 according to the present embodiment, as shown in FIG. 5, the lower pachinko ball can easily escape along the guide bottom surface 38 even if the lower pachinko ball is pressed against the guide bottom surface 38 by the pressure of the upper pachinko ball. In addition, a guide bottom surface 38 that is provided below the pair of opening and closing members 30a and 30b and guides the pachinko balls received in the inclined state toward the rear is formed in an arc shape, and the guide protrusion 21 is sandwiched between the center lines. By forming the curved surface radius on the side not provided larger than the curved surface radius on the side on which the guide projection 21 is provided across the center line, the start winning device 5 is won and guided as shown in FIG. The pachinko balls merged on the side where the protrusions 21 are not provided can be smoothly introduced into the ball inlet 13.
[0027]
In the above-described embodiment, the winning device 5 has been described as the starting winning device 5 having a starting function with respect to the variable display device 3, but it is not always necessary to use the winning device 5 having the starting function, and another accessory is activated. May be used as a prize-winning device. Further, the arrangement position may be any position on the game board 2.
