TECHNICAL FIELD The present invention relates to a pachinko ball socket which is attached to a board surface of a pachinko machine or the like.

[Conventional technology]

Various pachinko ball receivers are arranged on the board surface of the pachinko machine, and the pachinko ball receiver, which is called a tulip, is popular among players. This tulip is provided with a pair of wings that can be opened and closed, and when a ball enters between the wings, the tulip is opened and catches the ball flowing down the board surface.

By the way, the opening and closing control of this tulip wing piece
As described in JP-A 62-101585, a weight is attached to a rotatable blade piece opening / closing member for opening / closing the blade piece, and the blade piece opening / closing member is rotated to a closed position for closing the blade piece by balance. I am trying. Then, the wing piece opening / closing member is rotated to the open position for opening the wing piece by the weight of the ball entering between the wing pieces, and is held at this position by the attractive force of the magnet.

[Problems to be Solved by the Invention]

However, in the above-described conventional device, if the weight is made heavy to stably hold the winglet opening / closing member at the closed position, the wingpiece opening / closing member cannot be rotated to the open position by the weight of the ball. It is difficult to stably hold the winglet opening / closing member in the closed position by increasing the weight. Therefore, there is a problem that the winglet opening / closing member in the closed position is rotated by the vibration applied to the pachinko machine and the winglet is opened.

The present invention solves the above-mentioned drawbacks of the conventional device, smoothly rotates the winglet opening / closing member, and stably holds the winglet opening / closing member not only in the open position but also in the closed position. An object of the present invention is to provide a tulip capable of reliably controlling opening / closing of a wing piece.

[Means for Solving the Problems]

In order to achieve the above object, the present invention fixes a first magnetic body to a blade opening / closing member that opens and closes a pair of blades that are openably and closably supported between an open position and a closed position. Since the second magnetic body is arranged in the middle of the moving range of the body, when this winglet opening / closing member is rotated by the weight of the sphere, the urging force due to the repulsive force generated between the winglet opening / closing member and the first and second magnetic bodies causes The winglet opening / closing member is selectively urged to one of a first position for moving the winglet to the open position and a second position for moving the winglet to the closed position, and the first and second The positions are alternately positioned.

Further, in order to achieve the same object, another invention is a pair of wing pieces that are openably and closably supported, and a sphere that is inserted between the wing pieces when closed to rotate the wing pieces to a first position. An opening lever, an opening / closing control lever for rotating the opening lever to a second position for receiving the ball entering between the blades when the blade is opened, and closing the blade, and the opening lever. The first magnetic body fixed to the first magnetic body is disposed so as to face the middle of the moving range of the first magnetic body, and a repulsive force is applied to the first magnetic body to move the release lever to the first and second positions. And second magnetic bodies that are alternately positioned.

[Action]

According to the above configuration, when the winglet opening / closing member is moved to the first position by the sphere that has entered between the winglets, it is stably held at the first position by the repulsive force of the first and second magnetic bodies. It In addition, the winglet opening / closing member rotated from the first position to the second position by the ball captured by the wingpiece is stably held at the second position by the repulsive force of the first and second magnetic bodies. Will be done. Therefore, the wing pieces can be controlled to open and close without causing a malfunction due to vibration or the like applied to the pachinko machine during the game. Also,
According to another invention, when the opening / closing lever is moved to the first position by the ball entering between the winglets, it is stably held at the first position by the repulsive force of the first and second magnetic bodies. . Then, the opening / closing control lever that rotates by receiving the ball captured by the wing pieces moves the opening lever moved to the second position to the second position stably by the repulsive force of the first and second magnetic bodies. Will be retained.

An embodiment of the present invention will be described below with reference to the drawings.

〔Example〕

In FIG. 5 showing the appearance of the pachinko machine, the pachinko ball fired by operating the handle 2 flows down on the board surface 3. In the process of this flow down, the pachinko ball changes its route variously by obstacle nails, windmills, etc. and wins the winning hole 4, tulip 5, starting hole 6 or is collected in the out hole 7. In addition,
At the center of the board 3, a winning ball device 10 including a display 8 and an attacker 9 is attached. When the digital number displayed on the display unit 8 satisfies a specific condition, the attacker 9 is opened. When this attacker 9 is opened, a large number of pachinko balls launched thereafter win the prize, and many prize balls are paid out.

FIG. 1 shows a tulip 5 of the present invention. The tulip 5 is fixed to the board surface 3 with screws or the like via a substrate 15. A vertically long rectangular opening 16 is formed in the center of the substrate 15. A pair of openings 17 are formed so as to sandwich the opening 16, and a colored plastic lens 18 is fitted into the opening 17. A lamp 19 is mounted behind the plastic lens 18. When the colored plastic lens 18 is used, the color of the wing piece 20 described later is preferably milky white.

Pins 21 are planted below the openings 17, and a pair of wing pieces 20 are rotatably attached to the pins 21. A cover 26 is attached to the substrate 15 so as to cover the pair of wings 20. And this cover 26 and wings
A flow path for a pachinko ball is formed by the R surface 22 formed on the side surface facing 20. The pachinko ball that has entered between the pair of closed wing pieces 20 is sent to the upper surface of the opening / closing lever 23 protruding in the center of the opening 16 through the flow path. The opening / closing lever 23 engages with the lower end of the blade 20 to hold the blade 20 in a closed state. An arm having a ball receiving portion 24 is formed below the opening 16.
25 is protruding. The arm 25 interlocks with the opening / closing lever 23. The ball receiving portion 24 is an open wing piece.
It receives the pachinko ball captured by 20 and sends it into the opening 16. In this embodiment, the arm 25 is connected to the opening / closing lever 23.
However, it may be formed integrally.

An L-shaped box frame 30 as shown in FIG. 4 is attached to the back surface of the substrate 15 so as to cover the opening 16.
A pair of bosses 32, 33 for holding the printed circuit board 31 are formed on the side surface of the box frame 30. A shaft 34 that pivotally supports the arm 25 is inserted into the box frame 30 so as to be sandwiched between the pair of bosses 32 and 33. A shaft 35 that pivotally supports the opening / closing lever 23 is provided above the shaft 34. On the right side of the shaft 35, a magnet 36 that holds the opening / closing lever 23 by being repulsed from a magnet described later is attached.

A pin 38 planted on the opening / closing lever 23 projects into a notch 37 formed on the front side of the box frame 30.
A magnet 39 is fixed to the tip of the. A hall element 40 is attached to the printed circuit board 31 facing the magnet 39. By moving the magnet 39, the Hall element 40
A pachinko ball passing between the winglets 20 is detected. Further, below the opening / closing lever 23, a pin 41 that abuts on the opening / closing lever 23 and restricts a turning end is attached.

FIG. 2 shows the inside of the box frame 30 with the wing pieces 20 closed. On the upper surface of the opening / closing lever 23 located in the center of the box frame 30, a guide portion 42 is provided along the longitudinal direction thereof.
A stopper 43 is formed at the right end. Then, the guide portion 42 has a protrusion 44 formed inside the box frame 30.
Are in contact. Further, a magnet 45 is attached to the opening / closing lever 23 so as to face the lower half of the magnet 36. The magnets 36 and 45 are arranged so as to face each other with the same polarity so as to repel each other.

Due to the repulsive force of the magnets 36 and 45, the opening / closing lever 23 tries to rotate counterclockwise, but the opening / closing lever 23 comes into contact with the protrusion 44 and is prevented from rotating, so it stops at the position shown in the figure. Like At this time, the right end portion of the arm 25 is in contact with the lower right end portion of the opening / closing lever 23, and the ball receiving portion 24 is located below the opening 16.

The operation of the tulip 5 of the present invention thus configured will be described. In FIG. 2 showing a state in which the winglets 20 are closed, the pachinko balls that have entered between the winglets 20 are the winglets 20.
And is sent to the upper surface of the opening / closing lever 23 via the flow path formed by the cover 26. This sent pachinko ball rolls on the upper surface of the opening / closing lever 23 that descends to the right, and is a stopper formed at the right end.
Stopped at 43.

At this time, the weight of the pachinko ball overcomes the repulsive force of the magnets 36 and 45, and the open / close lever 23 rotates clockwise. By this rotation, the arm 25 engaged with the opening / closing lever 23 also rotates clockwise. The rotation of the opening / closing lever 23 and the arm 25 is continued until the opening / closing lever 23 comes into contact with the pin 41, and the ball receiving portion 24 is located above the inside of the cover 26 and the wing piece 20 disengaged from the opening / closing lever 23. Shifts to the open state by its own weight and stops at the position shown in FIG. The pachinko ball rolls forward on the slope formed on the opening / closing lever 23 and is discharged to the outside of the box frame 30. At this time, the Hall element 40 facing the magnet 39 generates a voltage. This change in voltage is detected and used as a lighting signal or a winning signal of the lamp 19.

In this state, the lower half of the magnet 45 faces the upper half of the magnet 36, so that the repulsive force between the magnet 45 and the magnet 36 acts to rotate the opening / closing lever 23 in the clockwise direction. Therefore, even if the pachinko ball rolls down from the opening / closing lever 23, the opening / closing lever 23 is stably maintained in the illustrated state.

In Fig. 3, the pachinko ball captured by the wing piece 20 is the R plane.
It is guided by 22 and falls on the ball receiving portion 24. The ball receiving portion 24 on which the pachinko ball is placed overcomes the repulsive force of the magnet 36 and the magnet 45 to rotate the arm 25 in the counterclockwise direction and presses the engaging open / close lever 23. The pressed open / close lever 23 rotates counterclockwise until it engages with the protrusion 44. At the time of this rotation, the opening / closing lever 23 engages with the lower end of the wing piece 20 and pushes it downward. Due to this pressing, the wing pieces 20 rotate about the pins 21 respectively and shift to the closed state.

By the way, the tulip 5 of the present invention uses the repulsive force of the magnet to prevent the opening / closing lever 23 from rotating and holds the wing piece 20 in the closed position. It is possible to control the opening and closing of the wing pieces more accurately than a conventional tulip in which a weight is incorporated in the opening and closing lever and the wing piece is closed by its own weight.

〔The invention's effect〕

As described above, according to the pachinko ball receiver of the present invention, the pair of wing pieces that are supported to be openable and closable, and the first position where the wing pieces are opened by the ball that is inserted between these wing pieces. And a second position for closing the wing piece, the wing piece opening / closing member that is alternately rotated, the first magnetic body fixed to the wing piece opening / closing member, and the moving range of the first magnetic body. It is arranged facing the middle,
Since the winglet opening / closing member is provided with a second magnetic body that alternately positions the winglet opening / closing member to the first and second positions by moving the first magnetic body, the sphere moves to the first position and the second position. The winglet opening / closing member thus formed can be stably held by the repulsive force of the first and second magnetic bodies. Therefore, it is possible to prevent erroneous operation of opening and closing the wing piece due to vibration applied to the pachinko machine. Further, in another invention, since the winglet opening / closing member is composed of the opening / closing lever and the opening / closing control lever, the weight of the opening / closing lever can be reduced. Therefore, the opening / closing lever can be more stably held at the first and second positions even with the same repulsive force of the magnetic body.
