Description

[Detailed description of the invention] This invention is based on a pair of opening and closing blades that are pivoted on both sides of the front side of a vertically long ball inlet provided on a base plate, and which are capable of standing parallel and tilting in the opposite direction. A chuck is attached to the lower part, the bottom of which matches the bottom of the ball inlet, and when the opening/closing vane pair is erected within a guiding frame fixed to the back surface of the board behind the ball inlet, the front end of the blade is fixed to the bottom of the ball inlet. A ball guiding plate that intervenes below the supporting axis of the plate to maintain the upright position is pivotally supported, and when the pair of opening and closing blades is raised from one side of the lower surface of the ball guiding plate, the lower bottom of the chutka The conventionally known safe ball socket is improved and tilted by providing a contact piece that almost touches the top and faces immediately below between the horizontally opposing lower edges of the opening/closing blade pair when tilting. When a hit ball is captured on the pair of opening and closing blades, the ball is dropped into the gap formed by the notch formed on the lower edge of each pair of blades, and the ball that falls into the gap is prevented from standing up. The balls come into contact with the contact piece of the ball guide plate, and the weight of the ball lowers the contact piece until it almost touches the bottom plate of the chutzker.At the same time, the rear side of each of the above-mentioned notches of the opening/closing vane pair is attached to the left and right side edges of the front end of the ball guide plate. This is an improved device in which the sliding piece provided on the blade is rubbed, and the sliding blade pair is guided and maintained in the upright position only by the sliding action, unlike the conventional method where the opening and closing blade pair was tilted. When the ball is in contact with the ball, the weight of the ball causes the pair of vanes to rise and the contact piece of the ball guide plate is pushed down, thereby causing the front end of the ball guide plate to lower. The object of this invention is to make the ball contact the contact piece first and to cause the pair of opening/closing vanes to rise only by the lowering action of the front end of the ball guide plate, without being affected by the weight of the ball.

To explain one embodiment of the present invention, reference numeral 1 in the figure is a board to be attached to the front surface of a plywood board of a pachinko machine, and a pair of opening/closing wing boards 3, 3 are attached to the left and right sides of the front face of a vertically long ball entrance 2. It is supported by support shafts 4, 4.

In addition, a lower bottom 6 is attached to the ball inlet 2 at the lower part of the opening/closing vane pair 3, 3.
Attach the chucker 5 that matches the bottom of the ball inlet 2, and fix the guide frame 1 to the back side of the board 1 behind the ball entrance 2, and then The ball guide plate 9, which is pivotally supported by the shaft 8, is provided with a front end 10 that slightly protrudes from the ball inlet 2 when in the lower position as shown in FIG. 11, 11 are provided.

In addition, on the ball guide plate 9, a lower projecting piece 12 that projects downward from one side of the lower surface near the front side of the horizontal shaft 8 has a third opening/closing wing plate pair 3゜3.
It stands up as shown in the figure, and the ball guide plate 9 supports the front end 10 on the support shaft 4,
4, and the blade pair 3 is lowered by the sliding edge 11°11.
, 3 is in the state of standing up, the bottom of the chutka 5 6
A contact piece 13 is provided that is substantially in contact with the top.

In this embodiment, in the above-mentioned well-known structure, a pair of opening/closing vanes 3,
A notch 14, which forms a gap 15 in which the ball falls onto the contact piece 13 when the ball is tilted as shown in FIGS.
14 is provided at the rear of each notch, and the sliding edges 11, 11 of the ball guide plate 9 lowering the front end 10 from the posture shown in FIG. 2 to the position shown in FIG. Wing plate pair 3,
The pieces 16, 16 to be rubbed and rubbed that guide the parts 3 to stand up are formed in the form of protruding pieces.

In the embodiment described above, the opening/closing blade pair 3, 3 stands up as shown by the chain line in FIG. 1 and FIG. The ball a1 that enters when
The ball guide plate 9 passes through the ball inlet 2 from above the support shafts 4, 4.
The ball flows upward and roughly from the rear end of the iron plate 9 to the outside of the guide frame 7, and due to the weight of the balls at that time, the front end of the ball guide plate 9 springs up as shown in Fig. 2, and the center of gravity shifts to the supporting axis. 4, by tilting the opening/closing vane pair 3, 3 which are located above and outward from the notches 14.14.
As clearly shown in FIG. 4, a gap 15 is formed through which the next ball can freely flow down from the center.

At that time, the sliding pieces 16, 16 are turned upside down together with the opening/closing vane pair 3, 3, and the sliding edges 11, 11 of the ball guide plate 9 are placed on top of them.
corresponds, and at the same time, the contact piece 13, which would have faced the immediate lower part between the horizontally opposed lower edges of the opening/closing vane pair 3, 3 if there were not the notches 14, 14, is now exposed due to the notches 14, 14. As clearly shown in FIG. 4, it is located below the center of the gap 15.

In this state, when the ball a2 enters the pair of opening and closing vanes 3, 3 and is captured, it falls through the gap 15.

For this reason, normally, the weight of the hit ball a2 causes the opening and closing blade pair 3,
3 begins to stand up due to the presence of the notches 14, 14 at the central portion beyond the support shafts 4, 4 of the pair of vanes 3, 3, substantially at the opposing lower end edges of the pair of opening/closing vanes 3, 3. Since no weight is applied to the pair of blades 3, 3, the blade pair 3, 3 is not given any opportunity to start standing up on its own, so the ball a2 falling into the gap 15 comes into contact with the contact piece 13, and at that time Due to the weight of the ball, the contact piece 13 is lowered onto the bottom plate 6 of the chucker 5 as shown in FIG.

For this reason, the front end of the ball guide plate 9 is also lowered, and while the sliding edges 11, 11 are pushing down the sliding pieces 16, 16, the six pieces 16, 1
6 Slide the top downward.

As a result, the weight of the ball a2 does not act on the pair of opening/closing vanes 3, 3, and the rubbed pieces of the sliding edges 11, 11 of the ball guiding plate 9 lower the front end 10 due to the weight of the ball a2. It stands up only by the action of pressure and rubbing against 16 and 16.

Therefore, the sliding edges 11, 11 do not follow the opening/closing vanes 3, 3 that rise due to the action of the ball, unlike the conventional ones, but the sliding edges 11, 11 move the pieces 16, 16 to be rubbed by the sliding edges 11, 11. Since it is pushed downward from the support shafts 4 and 4, the opening/closing wing plate 3゜3 is the ball guiding plate 9.
As a result, the robot stands up as described above, and is maintained in the standing position at the end when the state shown in FIG. 3 is reached.

As clarified by the description of the above embodiments, the present invention has the following features:
Notches 14, 14 forming a gap 15 through which a ball gently flows down between the opposing lower edges when the opening/closing blades 3, 3 are tilted in the opposite direction, and the sliding portion on the rear side of each of the notches. Piece 16,1
6, the ball caught on the tilted opening/closing blades 3, 3 first comes into contact with the contact piece 13 of the ball guide plate 9, and the contact piece 13 descends and the ball guide plate 9 The sliding edges 11 on both sides of the front end of the iron plate 9 are lowered, thereby lowering the front end of the iron plate 9.
The sliding blade pair 3, 3 is configured to apply a sliding pressure of Ll to the rubbed pieces 16, 16 to make the pair of opening/closing blades 3, 3 stand up without being affected by the direct pressure of the ball. This has the effect that the mechanism for forcing the player to stand up can be configured without being based on direct contact with the ball.
