It is publicly known from 94080 and the like.

[Problems to be Solved by the Invention] These conventional prize-winning devices were equipped with a detection means, but due to the structure of the oscillator, the oscillation was small, and as a result, the installation location of the detection means was restricted, making it difficult to incorporate the detection means. It was extremely difficult. In particular, in devices that use permanent magnets as detection means, the installation space is narrow and the oscillating width of the oscillating body is small, so there is a risk that the detection means may interfere with each other, which may cause malfunctions. Ta.

In view of the above-mentioned conventional problems, the present invention improves a rotary tulip-type winning device in which the ball holder rotates a rotating body to change the winning conditions by the repulsion-attraction action of a permanent magnet. The detection means are incorporated without mutual interference so that an accurate signal can be generated every time a winning ball hits.

Means for Solving Problem L] That is, the present invention includes a mounting board that opens a prize opening and has a box-shaped frame behind it, and a spindle mounted on the front surface of the mounting board that is rotatably supported. The ball bearing includes a rotating body, and a rocking body rotatably supported on a support shaft installed horizontally inside the frame, and the ball bearing is located behind the rotating body. The rotating body is equipped with at least a pair of permanent magnets with different polarities on its back side, sandwiching the spindle, and the oscillator has permanent magnets that protrude radially at an angle of about 80 degrees about the horizontal spindle. 1. The first receiving piece is provided with a second receiving piece and a guiding piece protruding from the opposite side of the first receiving piece. Each free end of the second receiving piece is equipped with a permanent magnet having different polarity on the left and right, and by bringing the free ends of these receiving pieces alternately close to the back of the rotating body, the repulsion and attraction of the permanent magnets are performed. In the prize-winning device configured to rotate and stop the rotating body, when the first and second receiving pieces of the oscillating body move away from behind the rotating body, the swing locus of the free end is set on the frame of the mounting board. A winning device for a pachinko machine is characterized in that the winning device for a pachinko machine is provided with a detection means for detecting the free end corresponding to the middle of the swinging body, and is configured to obtain a signal in accordance with the rotation of the rocking body.

Hereinafter, embodiments illustrating the present invention will be described in detail.

[Example] Fig. 1 is an exploded perspective view of a winning device according to the present invention, and Fig. 1 is an exploded perspective view of a prize winning device according to the present invention.
Figure 3 is a partially cutaway front view, and Figure 4 is a rear view. In Figure 0, numeral 1 is a mounting board that is attached to the game board, and 2 is a frame that is integrally provided on the back of this mounting board. 3 is a rocking body that is freely rotatably supported on a support shaft 4 installed horizontally inside the frame 2; 5 is a ball bearing that is freely rotatably supported on a support shaft 6 that is installed in the front surface of the mounting board 1; It’s the body! The rotating body 5 is vertically 2
It has two entry lowers a and 7b, one entry lower a has a wall 8 on the left and right to make it narrow enough to allow one pachinko ball to pass through, and the other entry lower b has walls 8 on the left and right. It is equipped with a pair of rotating blades 10 that swing around the support shaft 9, and when the entry port faces upward, it can rotate outward using its own weight around the support shaft 9 to expand the entry width. A pair of permanent magnets 12a with different polarities on the left and right are arranged on the back side of the rotating body so as to sandwich the bearing hole 11 through which the support shaft 6 is passed.
12b is buried.

On the other hand, the mounting board l has a prize opening 13 in the center of the upper part and communicates with the inside of the frame body 2 provided at the back, and the ball received through the two flying lowers a and 7b of the rotating body is passed from this prize opening. It is designed so that it can be guided inside the frame and fed into the rocking body 3.

The rocking body 3 includes a first receiving piece 3a and a second receiving piece 3b that protrude radially at an angle of approximately 90 degrees around the shaft bearing 14, and further includes a first receiving piece 3a and a second receiving piece 3b.
The first receiving piece 3a and the second receiving piece 3b have permanent magnets 15a and 15 with opposite polarity at each free end, respectively.
b is integrally buried. The guide piece 3C has an arm 16 extending from its free end and a weight 17 at the tip.

This rocking body 3 can freely rotate around the support shaft 4, and always keeps one of the receiving pieces 3a, 3b horizontal with the weight 17, and its free end The permanent magnets 15a and 15b are protruded forward and exposed to the rear of the mounting board 1, and are buried close to the back surface of the rotating body 5 which is supported on the support shaft 6. It is intended to be done.

In FIG. 5, the first receiving piece 3a of the rocking body 3 is held horizontally,
A state in which the permanent magnet 15a provided at the free end of this is brought close to the back surface of the rotating body 5 is shown. At this time, the magnet 15a of the first receiving piece 3a and the magnets 12a, 12 of the rotating body 5
b is attracted and the concave part 19 of the rotating body fits into the convex part 18 provided on the front surface of the mounting board l, and the rotating body is thereby restrained in the state shown in FIG. It faces upward and communicates with the prize opening 13.

In this state, when a batted ball enters the flying lower a and transfers onto the first receiving piece 3a through the winning hole 13, the winning ball moves onto the rear guiding piece 3C according to the slope of the receiving piece 3a, The center of gravity will be moved rearward around the support shaft 4. Therefore, the guiding piece 3C is pushed down and the second receiving piece 3b is transformed horizontally, and the permanent magnet 15 whose free end has reversed polarity.
b is brought close to the permanent magnets 12a and 12b of the rotating body 5. As a result, since the same poles face each other, there is a repulsion, and the rotating body 5 moves forward along the support shaft 6 to disengage the convex portion 18 and the concave portion 19, and the repulsive action causes the rotating body to rotate, causing a difference. Extreme.

After the permanent magnet is attracted and rotated 180 degrees, the convex portion 18 and the four portions 19 are fitted together again to restrain the rotation of the rotating body.

FIG. 3 shows the restrained state after this 180 degree rotation. By this rotation, the rotating body 5 turns the large entry lower b upward and opens the left and right rotary blades 10 to the left and right to facilitate the entry of the ball. When the ball flies into this upward flying lower b, it passes through the winning hole 13 and passes through the second receiving piece 3b.
Climb onto the top and push it down to return the first receiving piece 3a to the horizontal position again, and then remove the permanent magnet 15a and the permanent magnets 12a, 12.
The repulsion and attraction of b causes the rotating body to rotate 180 degrees again, changing its entry port from a large one to a small one.

In the figure, 20 is a Hall element as a detection means, 21 is a printed wiring board, and 22 is a lamp mounted on the front surface of this wiring board to illuminate the rotating body from behind the mounting board 1.

Here, the Hall element 20 is provided on the side wall of the frame 2 in a position corresponding to the middle of the trajectory through which the free end of the receiving piece 3b passes when it hangs down from a horizontal position about the support shaft 4.

On the other hand, the lamp 22 is arranged vertically along the left and right side walls of the frame 2.
The tip of the lamp is inserted into a cap-shaped recess 23 provided on the mounting board so that it faces behind the rotating body.
This is meant to be illuminated.

The Hall element 20 is a permanent magnet 1 provided at the free end of the receiving piece 3b.
When the oscillator 5b passes as the oscillator 3 rotates, it generates electricity due to its magnetic force and emits an electrical signal.This minute voltage is amplified in an amplifier (not shown) and the lamp 2
Assume that the switch connected to the second power supply circuit is activated.

In installing this Hall element 20, the reason why the present invention makes it face in the middle of the rotation locus of the free end of the receiving piece is as follows.
This is to act on the element by the magnetic force received momentarily when it passes during rotation, thereby preventing malfunction. Therefore, in this embodiment, the middle of the rotation locus of the receiving piece 3b, which rotates within a range of approximately 80 degrees. Please set it in position.

In this embodiment, as described above, the case where one Hall element 20 is made to correspond to the receiving piece of the oscillator is explained, but there is a second Hall element 20 in the middle of the rotation locus of the free end of the first receiving piece 3a. A second signal can be obtained by arranging Hall elements opposite to each other.

Since this second signal is obtained separately from the first signal, it can be advantageously used when controlling the winning conditions of a winning device other than the winning device of the present invention.

[Effects of the Invention] The winning device of the present invention has been described above with reference to the embodiments. As mentioned above, the winning device of the present invention has a structure in which the prize winning device of the present invention corresponds to the free end of the receiving piece of the rocking body that swings when the winning ball enters. The detecting means is placed in the middle of the rotation locus, and each time the rocking body receives the winning ball and rotates, the magnetic force of the permanent magnet provided at the free end acts on the detecting means and a signal can be obtained. In addition to being able to be used to connect to the switch of the lamp provided with the lamp, it can be used to display a light when the winning conditions become favorable.
This signal can also be used in other winning devices to open and close doors that block the winning openings.

In particular, in the device of the present invention, when facing the permanent magnet provided at the free end of the receiving piece of the oscillator, which is a Hall element serving as the detection means, the oscillator is installed in the middle of its rotation locus, thereby causing the oscillator to fly the winning ball. Accurate detection is possible because the setting is made so that when the magnet rotates due to the magnet being turned, the passing of the - moment is detected and the magnet is influenced by the magnetic force of the permanent magnet. Since the installation position of this Hall element is away from the position where the receiving piece stops when the oscillator is in a normal state, it is not always interfered with by the permanent magnet, and therefore there is no possibility of error. The danger of operation can be effectively avoided.
