Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a variable prize winning device for a pachinko machine in which a rotating body located on the surface of a game board is rotated by the action of a permanent magnet, and can be changed between a state in which it is difficult for a ball to enter and a state in which it is easy to enter the ball. It is something.

Conventionally, as a variable winning device for pachinko machines that converts between a first state in which it is difficult for a ball to enter and a second state in which it is easy to enter a ball,
There is a so-called tulip-shaped winning device. However, this type of winning device only converts between the first state and the second state by opening and closing the left and right movable wings each time a ball is hit, so there is little change due to the conversion operation. Furthermore, the tip of the swinging bottom plate is exposed between the two rotating blades, and the state of both rotating blades is changed by the swinging of the swinging bottom plate, making the structure complex and requiring high precision in assembly. Also, since the tip of the swinging bottom plate is in direct contact with the lower end of the movable wing piece and pressed, the frictional resistance is large, so when converting by electrical means, a powerful large electric A physical driving source is required.

The present invention has been proposed in view of the above, and includes providing a first receiving part and a second receiving part in a back-to-back manner on a rotatable body provided on the surface of a substrate, and fixing permanent magnets on the left and right sides. A conversion frame with a permanent magnet fixed inside the guide frame on the back of the board is rotatably arranged, and the conversion frame is rotated by the ball entering the guide frame and the external operation of the lever extending outside. The rotating body is rotated by the magnetic action of a permanent magnet, and the receiving state of the ball is changed by the large rotational movement of the rotating body, thereby increasing the interest of the game and diversifying the game contents.

The present invention will be described below based on embodiments shown in the drawings.

The ball has a first receiving part 5 which is vertically long and has a narrow width so that it is difficult for the ball to enter, and a second receiving part 6 which is horizontally long and which is easy for the ball to enter.
At the center of the height is a first permanent magnet 7 with its tip facing the rear surface.
, 7' are provided. This first permanent magnet 7゜7' is attached to the support shaft 3
The ends facing the rear surface of the rotating body q have different magnetic poles, for example, if the first permanent magnet 7 is the N pole, the other first permanent magnets
Permanent magnet 7' has an S pole.

A guide frame is provided on the back surface of the above-mentioned board, and a shaft 9 extending through the entire interior is installed in the center of the guide frame, and a conversion frame 10 is rotatably attached to this shaft.

The conversion frame 10 includes a tilting plate /2 provided with a bearing tube // through which a shaft passes through the front end, and left and right first receiving pieces /3, /3' extending forward from the front end of the tilting plate /2. 1st receiving piece/3゜13'
The second receiving pieces 13 and 73 have left and right second receiving pieces 13 and 73 located below the bearing tube 73 and extending forward from the bearing tube 73.
The width of the first gap 15 between `` and `` is longer than the diameter of the pachinko ball;
6 has a width shorter than the diameter of a pachinko ball. And if necessary, the first receiver pieces i, y, i3' and the I22 receiver/

On the other hand, second permanent magnets /9, /9' are provided on the lower surface of each first receiving piece /3, /3', and each second receiving piece /3' is provided with a second permanent magnet /9, /9'.
lI.

A third permanent magnet 20, 20' is provided on the lower surface of /≠'. This second permanent magnet /9, /9' is the first receiving piece /3
, /J' have different magnetic poles, for example, if the second permanent magnet 19 is the S pole, the other second permanent magnet l'
is the north pole. Furthermore, the third permanent magnets 20 and 20' not only have different magnetic poles, but also have second permanent magnets arranged one above the other.
19' have different magnetic poles, and if the third permanent magnet 20 is the north pole, the other third permanent magnet 20' is the south pole.

The conversion frame IO described above has the bearing tube l/ inserted through the shaft 9, so it can rotate freely within the guide frame, but the rotation range is restricted by the stoppers 27 and 2/' protruding from the side of the guide frame r. There is. The rotation range of the conversion frame 10 is such that the lower surface of the second receiving piece/Hiro hits the stopper 2/' and the first receiving piece/J is'
And tilting plate/2 Kaha! The first state of being horizontal and the tilting plate 1
The lower surface of the second receiving piece /l hits the stopper λ/,
/F' is between the second state where it becomes horizontal. When the conversion frame io is in the first state, the second permanent magnet /
iq' faces the first permanent magnets 7, 7' of the rotating body, and when the conversion frame 10 is in the second state, the third permanent magnets 20, 2
0' faces the first permanent magnet 7°7'.

A shallow groove-shaped guide piece is provided on the back surface of the substrate and is positioned at the center of the lower side of the through hole 2 and gently slopes downward toward the rear.

This guide piece n is in the first state when the conversion frame 10 is in the first state.
When the conversion frame 10 is in the second state, the converting frame 10 is located within the second interval part/O, and sends the batted ball flowing in from the through hole 2 backward. In addition, a hit ball outlet 23, #' is formed on the rear lower end and bottom surface of one side wall of the guide frame t, and the hit balls entering the guide frame l from the through hole 2 are collected from the outlet 23 or 23' to collect winning balls on the back side of the game board. Discharge into gutter (not shown).

The present invention is constructed as described above, and the conversion frame 10
When is in the first state, since the opposing first permanent magnets 7, 7' and second permanent magnets /9, /9' have different magnetic poles, the rotating body Hiroshi is in the first state due to the attractive action of both permanent magnets. It is stationary with the receiving part j facing upward. In this state, the first
Uke piece/,? , /3' and tilting plate /2! It is horizontal, and the guide piece 22 is located within the first interval lj.

When a batted ball enters the first receiving portion S in this state, the batted ball passes through the through hole 2, rolls on the guide piece n, passes through the first spacing portion 15, and is placed on the tilting plate 12. In this case, since the width of the first receiving part S is narrow, most of the batted ball that enters the first receiving part j will land on the guide piece n, but if necessary, the first receiving part /3, /J
A wall portion may be provided on the surface of the ball so that the ball that enters the first receiving portion rolls on the guide piece n and lands on the tilting plate 12.

When a batted ball is placed on the tilting plate 12, the conversion frame IO converts from the first state to the second state due to the weight of the batted ball, and the batted ball on the tilting plate 12 is ejected from the outlet 3 and becomes a winning ball.

When the conversion frame 10 enters the second state, the first permanent magnet 7°7' and the third permanent magnet 20, 20' will face each other,
Opposed left and right first permanent magnets 7, 7' and third permanent magnets,
2 (7, 20') have the same magnetic poles. Therefore, the rotating body Hiroshi moves away from the substrate l due to the repulsive force of the same magnetic poles, and rotates around the support shaft 3 as a fulcrum. As the magnetic poles approach, the magnet rotates due to the attractive force, and when the magnet rotates half a turn as a whole, the opposing first and third permanent magnets have different magnetic poles, so they are attracted and stopped.

Therefore, in this state, the second receiving part 6 faces upward, the first receiving part 5 faces downward, and the conversion frame 10 has the second receiving piece /V, /≠'
Kaha! The guide piece n is horizontally located in the second spacing part 16.

Since the second receiving part 6 has a long width, the ball that enters the guide piece n
It rests on either of the second receiving pieces /lI, /<4'.

If a batted ball that enters the second receiver part B lands on the guide piece n, it will be transferred, pass through the first interval part IS, be guided to the almost upright tilting plate 12, and be ejected from the ejection port 23 to become the winning ball. becomes. Therefore, in this case, the rotating body ψ does not rotate and the second receiving portion 6 remains in a state facing upward, so that the ball can easily enter the ball. However, the batted ball that entered the second receiving part B is either the second receiving piece /ll, /! When the ball lands on the ball, the conversion frame 10 rotates under the weight of the ball and enters the first state, and the ball is ejected from the lower outlet 23' and becomes a winning ball.

When the conversion frame io is in the first state, the first permanent magnets 7゜7' are opposed to the second permanent magnets /ri, /ri', and the first permanent magnets 7,
Since the left and right positions of 7' are different from the above, the first permanent magnets 7,
The second permanent magnets /9 and /9' facing 7' have the same magnetic pole. Therefore, the rotating body≠ rotates half a rotation while moving forward due to the repulsive force of both permanent magnets, and stops with the first receiving portion S facing upward.

With the second receiver 6 facing upward in this way, if the batted ball lands on the guide piece n and rolls, the rotating body will return to its original state.
However, when placed on the second receiving piece, the conversion frame 10 rotates by half a rotation, and the first receiving part 5 faces upward. Therefore, the rotating body may or may not rotate depending on the manner in which the ball is hit into the second receiver.

In addition, small protrusions J are provided above and below the support shaft 3 on the surface of the substrate, and shallow depressions 25 are formed on the top and bottom of the back surface of the rotating body ≠ to receive the support shaft 3, to improve the sharpness of rotation and rest of the rotating body. . In other words, the rotating body stands still due to the attractive force of the permanent magnet and rotates due to the repulsive force of the permanent magnet, so when it is stationary, the protrusion engages with the depression 2S and becomes stable, and when rotating, the rotating body moves forward due to the repulsive force. Moving. Therefore, the protrusions and the depressions do not cause any trouble when the rotating body rotates, and especially when the rotation is stopped, the protrusions engage with the depressions due to the attraction of the permanent magnet, so that the rotation body stops smoothly.

In addition, a lever is provided on one side of the conversion frame that protrudes from the outer surface of the guide frame, and this lever is pushed down from above or pushed up from below using an electromagnet, etc., to forcibly rotate the conversion frame and rotate the rotating body. Make it.

FIGS. 6 and 7 show a specific example of this, in which a lever 2B bent in the shape of a crank is provided on one side of the conversion frame 10 and protrudes from the outer surface of the guide frame t, and this lever 2B is provided with an electric drive source, For example, the tip of the electromagnetic solenoid 27 has an actuator U bent in an L-shape, which faces from above. The electromagnetic solenoid 27 is electrically connected to an electric control device that centrally controls each operation of the pachinko machine. For example, when a ball hits a particular winning hole on the game board, the electric control device The electromagnetic solenoid 27 is excited by this. When the electromagnetic solenoid 27 is excited, the actuator 2g engages with the lever 2B from above and pushes down the lever 26. When the lever 26 is pushed down, the conversion frame 10 rotates around the shaft as a fulcrum, converting the conversion frame 10 from the first state to the second state, so that the rotating body ψ rotates and the second receiving part 6 is raised. Turn the ball towards the target and convert it into a state where it is easier to receive the ball.

Therefore, according to this embodiment, when the first receiving part 5 faces upward and is in a state where it is difficult to receive a batted ball, even if the ball does not enter the first receiving part j at all, the conversion frame 10 is moved through the lever 26. It is rotated by external operation. Therefore, the conversion frame 10 can be rotated by the d-ball that has entered the guide frame and by the external operation of the lever arm.

In addition, the conversion frame may be converted from the second state to the first state by external operation of the lever, or the conversion frame may be alternately convertible between the first state and the second state.

Furthermore, the conversion frame may have any configuration as long as it has a permanent magnet and rotates a rotating body, for example, depending on the size, shape, etc.
The design may be changed as appropriate, such as the direction of rotation.

As is clear from the above, according to the present invention, a rotating body provided on the surface of a board is connected to a ball that enters the inside of the guide frame through a through hole formed in the board, and an external actuation of a lever that extends to the outside of the guide frame. By using the magnetic action of permanent magnets installed in the conversion frame that can be rotated with respect to each other, the rotating body is rotated to greatly change the state in which the ball enters, so the state of change of the rotating body each time a ball enters can be changed. Not only can the game be enjoyed, but by appropriately setting the conditions for externally operating the lever, the game can be diversified and the game can be made even more interesting.

In addition, the rotation of the rotating body is made to indirectly follow the rotation of the conversion frame by using the mutual magnetic action of the permanent magnets provided on the rotation body and the conversion frame, so the conversion frame can be rotated by simply applying a small force. Therefore, the electric drive source and mechanical interlocking mechanism that actuate the lever provided on the conversion frame can be made compact and have a simplified structure.
