Description

[Detailed explanation of the invention] This invention consists of a rotating body that has multiple receivers that allow the ball to enter in different states, and is rotated by a predetermined angle by the action of a permanent magnet each time a ball hits the receiver, and the receivers are sequentially converted. This invention relates to a variable winning device for a pachinko machine in which the winning mode of a batted ball is changed by changing the winning mode.

As is well known, some winning devices for pachinko machines change the difficulty of winning a ball by changing the weight of the ball or by operating a cam, crank, or electromagnet.

However, the conventional award winning devices described above have little variety, are too bulky to be installed in certain types of pachinko machines, and have little decorative value.

This invention allows the rotating body to rotate by a predetermined angle every time a ball is hit into the receiving part, which brings changes and decorative effects to the game board, and also makes it compact by rotating the rotating body using a permanent magnet. It can be done.

The present invention will be described below with reference to the illustrated embodiment. A support shaft 2 is provided protruding from the surface of a substrate 1 made of a material that is not affected by magnetism, such as synthetic resin or aluminum, and the center of a rotating body 3 can be freely rotated on the support shaft 2. Support.

This rotating body 3 has a plurality of ball receiving parts 4□, 4□,
43 are formed at equal intervals.

In the example of the drawing, the width is the narrowest and it is difficult for the batted ball to enter the first part.
The receiving part 4□, the second receiving part 42 which has a relatively long width and which allows the ball to enter easily, and the third receiving part 43 which has the longest width and which allows the ball to enter most easily are spaced apart from the center by 120 degrees and are equally spaced. It's a formality.

The number of lever receivers is not limited to the illustrated embodiment, but may be two, four, etc., and in the following description, for convenience, a case will be described in which three are formed.

The rotating body 3 includes a first permanent magnet 5□ corresponding to each of the receiving portions 41, 42, and 43.

5□, 53 are provided, and a first magnetic pole portion 61 at one end of each permanent magnet is provided.
゜6□, 63 faces the substrate 1.

Each of the first magnetic pole parts 61, 62, 63 has the same pole (N pole or S pole).

On the other hand, a through hole 7 is provided in the substrate 1 to guide the saw-hit ball entering the upward receiving portion to the back surface, and a batted ball guiding gutter 8 communicating with the through hole 7 is provided on the back surface of the substrate 1.

The guide gutter 8 has a horizontal section 9 that slopes gently downward and connects the upper end of the slope to the through hole 7, and a vertical section 10 that descends perpendicularly from the lower end of the horizontal section 9. A wide bulge 11 is formed in the middle, and a blade wheel 13 fixed to a rotating shaft 12 is positioned within the bulge 11.

The impeller 13 has three blades 14 arranged radially at equal intervals, so that when a ball falling from the horizontal part 9 to the vertical part 10 lands on any of the blades, it is affected by the downward force and its own weight. The impeller 13 is rotated by 120°.

The rotating shaft 12 projects from the vertical portion 10 toward the back surface of the substrate 1 and is coaxial with the supporting shaft 2, and the actuator 15 is fixed to the projecting portion.

The actuator 15 is bobbin-shaped and has an actuation plate 16 close to the back surface of the substrate 1 and a brake plate 17 close to the wall of the vertical portion 10.
Three permanent magnets 181, 182, 183 on the operating plate 16
and three third permanent magnets 19□, 19□, 193 are arranged alternately in a circle around the rotating shaft 12 at equal intervals,
The second magnetic pole portion 20 at one end of the second permanent magnet 180, 18°, 183. ．． 202, 203 and third permanent magnet 19. ,1
9□, one end of 193 and the third magnetic pole part 21□, 21□, 21
3 toward substrate 1.

The second magnetic pole parts 201゜20□, 203 are the same pole, and 4
Furthermore, the third magnetic pole parts 211, 212 and 213 have the same polarity, but the second magnetic pole part and the third magnetic pole part have different magnetic poles.

For example, if all the second magnetic pole parts are N poles, all the third magnetic pole parts are S poles, and each second magnetic pole part and third magnetic pole part act on the first magnetic pole part.

The brake disc 17 is disc-shaped and has three recessed receiving parts 22 formed at equal intervals on its outer peripheral surface, and has a protruding tip part 24 of a locking piece 23 having a spring action and having one end fixed to the outer surface of the guide gutter 8. is pressed against the outer peripheral surface of the brake disc 17 to restrict rotation of the actuator 15.

Note that an equilateral triangular recess 25 is provided at the center of the back surface of the rotating body 3, and an equilateral triangular protrusion 26 that fits into the recess 25 is formed on the surface of the substrate 1 to regulate the rotational state of the rotating body 3.

The present invention is constructed as described above, and includes the first magnetic pole parts 6+, 62.63 and the second magnetic pole part 20. ．． 202,2
03 is a different magnetic pole, and the first magnetic pole part 6□, 6□, 63
If the and third magnetic pole parts 2L, 21□, and 213 are the same magnetic pole, and if the first magnetic pole part and the second magnetic pole part are facing each other, the rotating body 3 is kept stationary by the attractive force of both poles.

When the rotating body is at rest, either receiving portion (the first receiving portion 4 in the drawing) faces upward and is in a state where a batted ball can enter.

When a batted ball enters the first receiving part 4□ in this state, the batted ball flows down the horizontal part 9 of the guide gutter 8 from the through hole 7, falls down the vertical part 10, and rides on the wing 14 in the bulge part 11. , the impeller 13 is rotated by 120° as described above.

When the impeller 13 rotates by 120 degrees, the actuator 15 similarly rotates by the rotating shaft 12, and the protruding portion 24 fits into the receiving portion 22 to accurately restrict rotation of the actuator 15.

When the actuator 15 rotates, the brake disc 17 rotates by 12 degrees, but when the brake disc 17 rotates approximately 60 degrees, the first magnetic pole portion 6. of the same magnetic pole. ．． 6□, 63 and third magnetic pole part 21
,．． 212 and 213 face each other, and a repulsive force acts.

This repulsive force causes the rotating body 3 to protrude forward, so the recess 2
5 is removed from the protrusion portion 26 and becomes in a free rotating state, and rotates due to the repulsive action of each magnetic pole portion.

When the brake plate 17 further rotates by 60°, the first magnetic pole portion 6□
, 6□.

63 and the second magnetic pole portions 20□, 20°, and 2o3, an attractive action is generated between the rotating body 3 and the rotating body 3 to rotate by 120', and the hollow portion 25 fits into the protrusion 25 and rotates. body 3
stop rotating.

In this state, the second socket 42 faces upward and can receive the batted ball.

When a ball hits the second receiver 4□, the rotating body rotates in the same way, and the third receiver 43 faces upward.

In this way, the impeller 13 and the actuator 15 are 120
When the rotating body 3 rotates by 120° due to the action of the permanent magnet,
The receiving part changes and the difficulty of hitting the ball changes.

When a ball hits this receiver, the rotating body rotates again due to the rotation of the impeller and the actuator, and the receiver changes again.

Therefore, each time a ball hits the receiver, the rotating body rotates greatly, enhancing the decorative effect and significantly increasing the interest of the pachinko game.

The above explanation shows the case where three receiving parts are provided, but in the case of two receiving parts, each of the first, second, and third magnetic pole parts is made into two, and the impeller can be rotated by 18 degrees when the ball is hit. In the case of four magnetic poles, the number of magnetic poles may be four, and the impeller may be rotated by 90 degrees when the ball is hit.

As is clear from the above, according to the present invention, when a ball is hit, the rotating body rotates greatly and changes the difficulty of hitting a ball, thereby adding interest to the pachinko game, enhancing the decorative effect, and reducing the size and size of the game. Since it can be created, it can be installed on any pachinko machine.

In addition, since it does not use electrical devices or mechanical devices such as cams and cranks, it will not be damaged or malfunction, and will operate reliably and require no maintenance, making it a winning device with high practical value. provide.

Note that the rotating body may be rotated by forcibly rotating the impeller or the actuator by a certain angle using electrical or magnetic means.
