Description

DETAILED DESCRIPTION OF THE INVENTION The present invention rotates a rotating body integrally formed with triangular protrusions to fix one apex corner of the protrusions at a vertically upper position or a vertically lower position, and thereby This invention relates to a ball entry guiding device for a pachinko machine that is capable of changing the winning interval and winning path of balls hitting a winning opening arranged in a pachinko machine.

As is well known, in a pachinko machine, a large number of obstacle nails are arranged on the game board surface, and the distance between the obstacle nails determines how well the balls hit and the winning path. In other words, machines with a high winning rate and machines with a low winning rate are determined from the beginning, and for this reason, those who can read the spacing between nails like pachinko professionals will always make money on the machines with a high winning rate. On the other hand, ordinary players end up sitting on empty machines with a low payout rate and often lose money in a short period of time, making pachinko games uninteresting.

The present invention eliminates the above-mentioned inconveniences by providing a ball guiding device that allows you to easily change the winning interval and winning path of the balls hit into the winning slot during play. One of its purposes is to significantly increase the interest of the game.

An embodiment of the present invention will be described below with reference to the drawings. In the figure, reference numeral 1 denotes a mounting plate integrally provided with a ball socket 2 having an open top on the front surface, and a circular recess 3 is formed approximately at the center of the front surface of this mounting plate 1. A support shaft 4 is provided protruding from the center of this recess 3, a fitting protrusion 5 is formed at the base of the support shaft 4, and small through holes 6 are drilled in the center on both sides of the support shaft 4. Small circular recesses 7, 7 are formed. A rotating body 8 is supported on the support shaft 4 so as to be rotatable and slidable back and forth.

The rotating body 8 has a circular plate 9 facing the recess 3 of the mounting plate 1, and has a cylindrical hole 10 in the center thereof, through which the spindle 4 is inserted, and small recesses 7, 7 on the back side on both sides around the cylindrical hole 10.
A permanent magnet 11 and a permanent magnet 12 that are fitted with the cylindrical hole 10 have different magnetic properties and are buried so as to slightly protrude toward the mounting plate 1, and a fitting convex portion 5 is provided at the base of the cylindrical hole 10.
A fitting recess 13 is provided for fitting. Regarding the permanent magnets 11 and 12, for example, in FIG. 5, if the protruding end of the right permanent magnet 11 is the north pole, the protruding end of the left permanent magnet 12 is the south pole.

Reference numeral 15 denotes a box frame connected to the back of the mounting plate 1, and an operating member 17 shown as a fixed control means for the rotating body 8 is pivoted to a horizontal shaft 16 extending inside the box frame so as to be tiltable up and down. ing. The actuating member 17 is made of synthetic resin, and an upper holding cylinder 18 and a lower holding cylinder 19 are vertically arranged at the tip thereof, and the upper holding cylinder 18 and the lower holding cylinder 19 have different magnetic pole arrangements. A permanent magnet 20 and a permanent magnet 21 are housed and held in a state in which they protrude from both ends. For example, if the right end of the permanent magnet 20 of the upper holding cylinder 18 is an N pole and the left end is an S pole, the permanent magnet 21 of the lower holding cylinder 19 has an S pole at its right end and an N pole at its left end. In addition, the operating member 1
A lever piece 22 protrudes from the rear end of the lever 7 and is linked to an appropriate interlocking operation member. When the actuating member 17 is in the forward upward position shown in FIG. 3 or in the forward downward position shown in FIG.
2, respectively. Also,
When the actuating member 17 is in the forward upward position, the apex portion 14a of the protrusion 14 of the rotating body 8 is fixedly held in the vertically upward position, and when the actuating member 17 is in the forward downward position, the rotating body 8
The apex portion 14a of the protrusion 14 is fixedly held in a vertically downward position.

Next, the effect will be explained. As shown in FIGS. 3 and 5, when the actuating member 17 is in the forward upward position, the right end magnetic pole (S pole) of the permanent magnet 21 of the lower holding cylinder 19 is the magnetic pole of the right permanent magnet 11 of the rotating body 8. (N pole) and the permanent magnet 2 of the lower holding cylinder 19.
The leftmost magnetic pole (N pole) of the rotor 8 corresponds to the magnetic pole (S pole) of the left permanent magnet 12 of the rotor 8 and attracts each other, restraining the rotor 8 so that it does not rotate. The apex portion 14a of is fixed at a vertically upper position.

Next, in this state, when the lever piece 22 is pulled upward and the actuating member 17 is moved forward and downward as shown in FIGS. 4 and 6, the right end magnetic pole (N The leftmost magnetic pole (S pole) of the permanent magnet 20 of the upper holding cylinder 18 corresponds to the magnetic pole of the left permanent magnet 12 of the rotating body 8. (S pole) and repel each other, and due to the repulsive force, the rotating body 8 moves forward on the support shaft 4 to engage the fitting convex portion 5.
and the fitting recess 13 and the small recesses 7, 7 and the permanent magnet 1
At the same time as the engagement with 1 and 12 is released, a rotational moment is applied, and the rotating body 8 rotates. When the apex portion 14a of the protrusion 14 of the rotating body 8 is reversed to the vertically downward position, the magnetic pole (S pole) of the permanent magnet 12 that has moved to the right of the rotating body 8 is connected to the permanent magnet of the upper holding cylinder 18. The magnetic pole (N pole) of the permanent magnet 11 moved to the left of the rotating body 8 corresponds to the rightmost magnetic pole (N pole) of the permanent magnet 20 of the upper holding cylinder 18, and the magnetic pole (S pole) of the permanent magnet 20 of the upper holding cylinder 18 corresponds to the leftmost magnetic pole (S pole) of the permanent magnet 20. The protrusions 14 are attracted to each other, restraining the rotating body 8 from rotating and fixing the apex portion 14a of the protrusion 14 in a vertically downward position.

In this way, the tilting operation of the actuating member 17 generates attraction and repulsion between the permanent magnets 11 and 12 of the rotating body 8, thereby rotating the rotating body 8 and moving the apex corner of the protrusion 14. 14a is fixed in a vertically upper position or a vertically lower position. Incidentally, the tilting operation of the operating member 17 is performed by linking the lever piece 22 with an electrical interlocking operation mechanism such as a solenoid, or with a mechanical interlocking operation mechanism such as a link motion operated by the weight of the ball. All you have to do is let them do it.

FIGS. 7 and 8 show an embodiment in which the present device having such a configuration and operation is placed above the prize opening 23 provided on the game board a. Therefore, when the apex portion 14a of the protrusion 14 of the rotating body 8 is fixedly held in the vertically upward position as shown in FIG. As a result, the winning path to the winning opening 23 is essentially closed, and the probability of winning is extremely low. In addition, since both corners of the bottom of the protrusion 14 are located above the obstacle nails 24, 24 of the winning hole 23, and the interval between the balls passing through is narrowed, the balls entering from the direction of the arrow C can win. is also very difficult.

In this state, when the rotating body 8 rotates and the apex portion 14a of the protrusion 14 is reversed to the vertically downward position and fixedly held as shown in FIG. 8, the ball _B1 falling from the arrow direction A' is You can enter the winning slot 23 without changing your course. In addition, the distance between the protrusion 14 and the obstacle nails 24, 24 where the ball passes is widened, making it easier for the ball to win from the direction of the arrow C'.

As described above, the ball guiding device according to the present invention rotates the rotating body and inverts the apex corner of one of the triangular protrusions protruding from the front surface of the rotating body to the vertically upward position or vertically downward position. Fix it. In particular, since it is possible to easily change the winning interval and winning path of the balls hit into the winning opening, the probability of winning can be changed and the interest of the game can be significantly increased.

In addition, since it is possible to change the winning rate while playing, the winning rate is determined from the beginning by how the obstacle nails are hit, unlike in conventional pachinko machines. Unlike other players, the average player can also enjoy the game to the fullest.
