Description

[Detailed description of the invention] The present invention consists of a pair of movable wing pieces that can stand up and tilt, and a movable wing piece that intervenes below the axis of the movable wing piece with its front end upright to maintain its upright position or to flip up the front end of the movable wing piece. A winning pachinko machine comprising: a ball guiding plate that causes a tilting motion; and a locking member that engages with an engaging member to hold the ball guiding plate in a position where its front end is interposed below the axis of a movable wing. Regarding the ball device, its purpose is to form a recessed step on the upper surface of the rear end of the ball guide plate, and to prevent the safe balls flowing backward on the upper surface of the ball guide plate by forming the recessed step. By making the ball contact the locking member while floating above the upper surface of the ball guide plate, the ball weight of the safe ball can be effectively applied to the locking member to ensure that the safe ball is disengaged from the engaging member. Thus, the raising and tilting operations of the movable blades can be performed accurately using the ball guide plate.

As mentioned above, in the case of a winning ball device configured to hold the ball guiding plate in the upright position of the movable wing by engagement between the locking member and the engaging member, the upper surface of the ball guiding plate is moved backward. If the speed of the safe ball flowing is fast, the lock member cannot be loaded with enough ball weight and it flows out from the outlet of the guide box, or conversely, if the speed of the safe ball is slow, the lock member If the locking member and the engaging member cannot be disengaged, for example, the ball may come into contact with the ball guide plate and get stuck on the top surface of the ball guide plate.
There is a risk of malfunction occurring in the tilting operation of the movable blade.

One object of the present invention is to eliminate such inconveniences, and an example of implementing the present invention will be described below with reference to the drawings. In the figure, reference numeral 1 denotes a mounting plate, on which a pair of movable blades 3, 3 are pivoted by shafts 4, 4 below the center on both sides of the front surface of a vertically long ball inlet 2 provided approximately in the center. A chuck car 5 is fixed so as to cover the front surface and lower portions of both sides of the chucks 3 and 3. Reference numeral 6 denotes a guide box that covers the rear part of the ball inlet 2 and is fixed to the mounting plate 1. Inside the guide box 6, there is a see-saw ball guiding plate 8 having a ball receiving piece 7 at the tip.
is pivotally supported by a horizontal shaft 9, and the ball guide plate 8 is in a substantially horizontal position with its tip lowered, and its tip is attached to the movable wing pieces 3, 3.
The movable blades 3, 3 are intervened below the shafts 4, 4 to hold them in the upright position shown by solid lines in FIG. Note that the ball guide plate 8 is formed so that a weight 10 is provided on the lower surface of the rear end so that the rear portion is heavier than the front portion.

An outflow port 11 is formed at the rear of the guide box 6, and a ratchet gear 12 shown as an engaging member is mounted on the outer surface of the side wall opposite to the outflow port 11 with a horizontal shaft 9.
It is coaxially supported. Reference numeral 13 denotes a reverse rotation prevention pawl that controls rotation of the ratchet gear in one direction.
Further, a lock member 14 is pivotally supported by a shaft 15 on the side surface of the rear end of the ball guide plate 8 so as to be swingable.
This locking member 14 integrally includes a lever piece 16 that protrudes into the inside of the guide box 6 and faces the upper surface of the rear end of the ball guide plate 8, and an engagement pin 17 that projects outward from the side of the guide box 6. The engaging pin 17 is always urged to rotate so as to come into pressure contact with the teeth of the ratchet gear 12. Further, the ratchet gear 12 has three tooth spaces 19, 19a, 19b, 19.
c, 19d are provided, and when the engagement pin 17 of the locking member 14 is engaged with this tooth groove 19 as shown in FIGS. 3 and 6, the tip of the ball guiding plate 8 is movable. The blades 3, 3 are held in a substantially horizontal position below the axes 4, 4.

In the winning ball device with such a configuration, when a safe ball enters between the upright movable wing pieces 3, 3, it flows backward from the ball inlet 2 on the upper surface of the ball guide plate 8 and is locked into the locking member 14.
The locking member 14 comes into contact with the lever piece 16 and flows out from the outlet 11 while swinging backward as shown by the chain line in FIG. 3 against the spring 18. As a result, the engagement pin 17 of the lock member 14 is removed from the tooth grooves 19, 19a of the ratchet gear 12, and the ball guide plate 8 is moved by the action of the weight 10 as shown in FIGS.
As shown in the figure, the movable wing pieces 3 are tilted by lowering the rear end and flipping up the front end. At the same time that the lever piece 16 is released from the weight of the ball, the lock member 14 returns to the position shown in solid line in FIG.
9, 19a, which engages the tooth 12' located immediately below.

Next, when the safe ball enters the tilted movable wing pieces 3, 3, it rides on the ball receiving piece 7, and the weight of the ball becomes the weight 1.
0, the leading end of the ball guide plate 8 is lowered and the rear end is raised to raise the movable blades 3, 3 one step. At this time, the engagement pin 17 engaged with the teeth 12' of the ratchet gear 12 causes the ratchet gear 12 to move to the fourth position.
It is rotated by one tooth in the clockwise direction shown by the arrow in the figure. Then, when the safe balls flow backward from the ball receiving piece 7 and the ball guiding plate 8 is released from the ball weight, the ball guiding plate 8 lowers its rear end again by the action of the weight 10 and the movable wing piece 3 , 3. When the ball guide plate 8 lowers its rear end, the locking member 14 follows and descends, and the engagement pin 17 slides on the tooth 12' against the spring 18 and is removed from the tooth 12', and at the same time the spring is released again. 18 and engages with the next tooth 12''.Then, each time a safe ball enters between the tilted movable blades 3, 3, the ball guide plate 8 repeats the same seesaw action as described above. Ratchet gear 1 each time
2 is rotated one tooth at a time, the tilting state of the movable blades 3, 3 is continued until the engagement pin 17 engages with the next tooth groove 19, 19b.

Therefore, in the winning ball device configured to hold the ball guiding plate 8 in the upright position of the movable wing pieces 3, 3 by the engagement between the lock member 14 and the engaging member such as the ratchet gear 12 as described above. In order to ensure accurate operation, it is absolutely necessary to ensure that the locking member 14 is disengaged by the weight of the ball.

In view of the above, the present invention forms a concave stepped portion 20 on the upper surface of the rear end of the ball guide plate 8, so that the lever piece 16 of the locking member 14 faces above the concave step 20, so that the safe balls can be placed on the ball guide plate 8. When flowing backward on the upper surface, the water comes into contact with the lever piece and disengages the locking member 14 from the ratchet gear 12, which is the engaging member, and falls into the recessed step 20 and exits from the outlet 11 of the guide box 6. The gist of this is that it was designed to flow out. The recessed step 20 is arranged so that the distance between the front step edge 21 and the lever piece 16 is at least shorter than the diameter of the safe ball, and the bottom surface is formed as an inclined surface facing the outlet 11.

Therefore, the safe balls flowing backward on the upper surface of the ball guide plate 8 are received by the step edge 21 of the recessed step 20 and the lever piece 16 in a state that they are raised from the bottom surface, and the lever piece You can strongly add ball weight to 16. For this reason, lock member 1
It is possible to reliably carry out the release operation of No. 4, and to obtain a prize winning ball device that operates accurately and does not cause any malfunction in the tilting operation of the movable wing.
