Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a pachinko machine equipped with a variable winning device that can rotate a rotating winning member between a disadvantageous state and a profitable state for the player. It is something.

<Prior art> In a conventional pachinko machine, when a player shoots a game ball and enters a variable prize winning device or winning device while it is flowing down while hitting an obstacle nail, the ball opens due to the weight of the winning game ball. When a game ball enters the ball again, the ball closes and the player is awarded a prize ball each time.

<Problems to be Solved by the Invention> However, in the conventional pachinko machine described above, the state change of the variable prize winning device cannot be arbitrarily selected and controlled, and is only controlled mechanically. It was not possible to proceed with the game while grasping the state of the prize-winning member used to win the prize.

<Means for Solving the Problems> The present invention has been proposed in view of the above, and includes a base plate that includes a rotatable winning member that can be rotated between a disadvantageous state for the player and a profitable state for the player. a variable winning device which is installed on the front side of the machine and whose state can be changed by an electric drive source, and a specific gaming state detection signal generator which detects when a preset specific gaming state has been entered and generates a specific gaming state detection signal. and driving the electric drive source of the variable winning device based on the specific gaming state detection signal from the specific gaming state detection signal generating means to disadvantage the rotary winning member based on predetermined conditions set in advance. drive control means for driving the conversion from a state to a profit state; and a state detection means for a rotary winning member, which is provided in the variable winning device and detects that the rotary winning member has changed to a profit state. It is something that

<Function> For example, when a game ball enters a specific winning state such as winning a prize in a specific winning device, the specific winning state detection means generates a specific gaming state detection signal, and based on this signal, the drive control means performs electrical drive. The variable prize winning device is converted into a profit state based on predetermined conditions set in advance by driving the source. In this case, for example, since the state detection means for the rotating winning member detects whether or not the rotating winning member is in the profit state, by using this detection signal, the state of the rotating winning member is reliably changed. be done.

<Example> Hereinafter, an example of the present invention will be described in detail with reference to the drawings. Reference numeral 1 indicates a variable winning device as a whole, which is composed of a rotating winning member 2 and a winning device main body 3. The rotating winning member 2 has a relatively narrow first socket 6A facing outward at one end around the shaft hole 5, and
At the other end position on the shaft hole 5 and the center line X passing through this shaft hole 5, a relatively wide second
The socket 6B is formed facing outward. Thus, when the first socket 6A faces upward, the player is at a disadvantage, and when the second socket 6B faces upward, the player is at a disadvantage.

In this embodiment, the sockets 6A and 6B are the front wall 7,
It has left and right walls 8L and 8R and a bottom wall 9, and when in the upper rotation position, game balls are received through an upwardly facing receiving opening and guided rearward through a rear opening 10.

The winning device main body 3 has a base plate 13 extending in the vertical direction, and a fixed shaft 14 extending forward is installed in the center of the base plate 13. At the base of the fixed shaft 14,
For example, a vertically elongated rectangular positioning piece 1
5 is fixed, and a locking groove 1 having an inner surface shape similar to the outer shape of the positioning piece 15 is located on the back side of the rotary winning member 2 facing the positioning piece 15.
6 is formed. The length of the fixed shaft 14 is set longer than the front and back thickness of the rotating winning member 2, so that when the rotating winning member 2 slides to the rear position close to the base plate 13, the positioning piece 15 fits into the locking groove 16. The sockets 6A and 6B are locked and fixed with the sockets 6A and 6B facing up and down. When the rotating winning member 2 separates from the base plate 13 and slides to the forward position from this state, the locking groove 16 escapes from the locked state of the positioning piece 15 and the rotating winning member 2 freely moves on the fixed shaft 14. It becomes possible to rotate.

A permanent magnet 17 serving as a weight is attached to an eccentric position of the rotating winning member 2, and when the rotating winning member 2 changes from a state with its sockets 6A and 6B facing up and down to a freely rotating state, the weight The permanent magnet 17 allows rotation to be started in either the left or right rotation direction.

Two permanent magnets 18L and 18R are provided at left and right positions symmetrical to the center line X across the shaft hole 5 on the back surface of the rotating winning member 2. The permanent magnets 18L and 18R have mutually different polarities, for example, N and S magnetic poles, respectively, exposed toward the back side. At positions on the base plate 13 facing these magnetic poles 18L and 18R, two magnetic poles 21L and 21R of an electromagnet 20 provided as an electric drive source are installed.
is located.

The electromagnet 20 has a U-shaped core 21, and this core 21 is fixed by a mounting bracket 25 to a lower chamber 24 of a guide gutter plate 23 that divides the case 22 into upper and lower parts, which is attached to the back surface of the base plate 13. . core 21
A coil 26 is wound around the center of the cord 27.
and is electrically led out to the outside of the case 22 via the connector 28.

Thus, when a positive excitation current is applied to the coil 26, the N and S polarities are applied to the magnetic poles 21L and 21R, respectively, and when a negative excitation current is applied, the S polarity is applied to the magnetic poles 21L and 21R, respectively.
and the polarity of the north pole are given. At this time, if the permanent magnets 18L and 18R of the same polarity face each other, the repulsive force forces the rotary winning member 2 to slide outward on the shaft 14, thereby bringing it into a freely rotating state and causing it to rotate further. On the other hand, when the magnetic poles 21L and 21R are opposed to the permanent magnets 18L and 18R of different polarity, the rotating winning member 2 is pulled inward on the shaft 14 by the attractive force and slides inward, thus moving the locking groove 16 into the positioning piece. 15 to lock it.

A central chamber 35 separated by a partition plate 34 is formed in the space above the guide gutter plate 23 of the case 22.
A game ball introduction port 30 is provided in the base plate 13 portion of the central chamber 35 so as to communicate with the rear opening 10 of the socket 6A or 6B of the rotating winning member 2. The game balls thus entering the upwardly facing sockets 6A or 6B are introduced into the central chamber 35 through the inlet 30 and are discharged through the outlet 36 provided at the rear of the central chamber 35.

In the case of this embodiment, the rear half of the lower chamber 24 is partitioned off by a partition plate 37, leaving the front half, and a game ball discharge lever 38 is provided in this rear half. The lever 38 has an L-shaped cross section, and a guide plate 39 extends rearward at approximately the same height as the guide gutter plate 23.
One end is rotatably supported on a shaft 40 just below the rear end of.

Also, when the case 22 is viewed from the back, an internal winning detector 45 configured as a micro switch, for example, is provided as a specific game state detection signal generating means at the clockwise rotating position of the lever 38, and the lever 38 is normally operated as an internal winning detector. 45 and is pushed by the actuating piece 46 to rotate counterclockwise as shown by the solid line. When the game ball 41 enters the guide gutter plate 23 from this state,
This falls from the guide piece 39 onto the lever 38 and moves it to the clockwise position. At this time, the internal winning detector 45 operates and electrically sends the winning detection signal D ₁ to the outside of the case 22 via the cord 47 and the connector 28 . When the lever 38 rotates clockwise, the game ball 41 that has fallen onto the lever 38 is discharged to the outside through the discharge port 36 provided on the left side of the case 22 when viewed from the front using this as a guide.

In addition, in FIG. 3, 48 is a magnetic shielding material.

Furthermore, an upper chamber 51 of the case 22 is formed above the partition plate 34 that forms the central chamber 35 . This upper chamber 51 connects an inlet 53 that communicates with an external specific winning device via a guide gutter 52 to the case 2.
A game ball discharge lever 56 is provided on the upper plate of the case 22 and discharges game balls 54 falling from the introduction port 53 to an outlet 55 formed in the back plate of the case 22. The lever 56 has an L-shaped cross section, and one end is rotatably supported on a support shaft 57.

At the clockwise rotation position of the lever 56 when viewed from the back side of the upper chamber 51, an external winning detector 58 configured as a micro switch, for example, is provided as a specific game state detection signal generating means. Pushed by the operating piece 59 of the detector 58, the fourth
In the figure, it is in a counterclockwise rotation state indicated by a solid line. When the game ball 54 comes from this state through the guide gutter 52 and falls onto the lever 56,
The lever 56 rotates to the clockwise position to operate the external winning detector 58. This external winning signal _D2 is
It is electrically led out of the case 22 via the cord 60 and further via the connector 28 . At this time, the game ball 52 that has fallen onto the lever 56 is discharged to the outside from the outlet 55 using the clockwise rotation of the lever 56 as a guide.

The guide gutter 52 can be connected to the specific winning device as shown in FIG. 5, for example. In this case, the specific winning device 63 is provided at the upper center of the game board, and has a pair of ejection ports 63A and 63B at the lower left and right positions of the winning tool. The game balls that have entered the specific winning device 63 in this way are discharged from either the discharge port 63A or 63B.

As shown in FIG. 5, the discharge ports 63A and 63B are connected to guide channels 65A and 65B of a pair of variable prize winning devices 64A and 64B, so that game balls 66 passing through the guide channels 65A or 65B
is configured to operate the external winning detector 58 of the variable winning device 64A or 64B, and then to be discharged from the discharge port 55 (FIG. 4).

However, the discharge ports 55 of these pair of variable prize winning devices 64A and 64B are further provided with guide channels 66A and 66B, and these guide channels 66A and 66
Inlet 53 of third variable winning device 67 through B
is connected to. In this way, the game balls that have passed through the pair of variable winning devices 64A or 64B operate the external winning detector 58 of the third variable winning device 67, and then fall from the discharge port 55 into the safe ball recovery gutter 68 of the back mechanism of the pachinko machine. It is done like this.

The detector 58 is the outlet 6 of the specific winning device 63.
It may be provided so as to communicate with 3A and 63B.

In addition to the above configuration, the socket 6A of the rotating winning member 2
The rotating position detector 70 detects which of the rotating winning member 2 and 6B is in the upward receiving position, that is, whether the rotating winning member 2 is in a profitable state or a disadvantageous state. The rotation position detector 70 functions as a state detection means for the rotation winning member, and is located on the back side of the right side wall 8R of the first socket 6A on the base plate 13.
A permanent magnet 17 is provided to face the permanent magnet 17 (FIGS. 1 and 2), and a reed switch 71 is attached to the lower left side of the base plate 13 (FIGS. 1, 2, and 3). , and the rotating winning member 2 is the second
The reed switch 71 is closed when the reed switch 71 reaches a rotation position in which the socket 6B is facing downward. At this time, the rotational position detection output D ₃ sent from the reed switch 71 means that the variable winning device 1 is in a disadvantageous state with a low winning rate, and is electrically connected to the case via the cord 72 and further via the connector 28. 22 to the outside.

The detection outputs D ₁ , D ₂ , D ₃ of the winning prize detectors 45, 58 and the rotational position detector 70, which are led out through the connector 28 in this way, are fed to a control circuit 75 as shown in FIG. The control circuit 75 electrically selects the state conversion of the variable prize winning device from the control circuit 75 to the coil 26 of the electromagnet 20 via the connector 28 based on predetermined conditions based on the detection outputs D ₁ and D ₂ . Excitation current is supplied.

The control circuit 75 has a 3-input AND circuit configuration.
Fourth rotation command circuits 76A to 76D and electromagnet 2
The coils 26 are connected in antiparallel to each other. It is connected to an AC power source 78 via thyristors 77A and 77B.

First, the first rotation command circuit 76A directly receives the internal winning detection signal D ₁ and also receives the external winning detection signal D ₂ and rotational position detection signal D ₃ via inverters 79B and 79C, respectively. Thus, as shown in the column of state 1 in FIG. 7, when the rotary winning member 2 is at the rotational position where the winning rate is small as shown in FIG. 1, if the internal winning detection signal _D1 arrives, the logic is "1" Generates output and outputs OR circuit 80
is applied to the gate of the positive direction excitation current thyristor 77A to turn it on, thereby causing the positive direction excitation current I to flow through the coil 26. The left and right magnetic poles 21L and 21R of the electromagnet 20 are excited to N and S poles, respectively, and the permanent magnets 18L and 18
Since R (N and S poles) are facing each other,
A repulsive force is applied to the rotary winning member 2 and it rotates. Therefore, the rotary winning member 2 is reversed from a disadvantageous state to a profitable state for the player.

Second, the second rotation command circuit 76B directly receives the external winning detection signal D ₂ and also receives the internal winning detection signal D ₁ and the rotational position detection signal D ₃ via the inverters 79A and 79C, respectively. Thus, as shown in the column of state 2 in FIG. 7, when the rotary winning member 2 is in a disadvantageous state for the player in FIG. 1, if the external winning detection signal _D2 arrives,
A logic "1" output is generated and applied to the positive excitation current thyristor 77A via the OR circuit 80 to turn it on, thereby causing the positive excitation current I to flow through the coil 26. Therefore, similarly to the first case described above, the rotary winning member 2 is reversed from a disadvantageous state to a profitable state for the player.

Thirdly, the third rotation command circuit 76C directly receives the internal winning detection signal D ₁ and the external winning detection signal D ₂ and also receives the rotational position detection signal D ₃ via the inverter 79C. Thus, as shown in the column of state 3 in FIG. 7, when the rotary winning member 2 is in a disadvantageous state for the player, if the internal and external winning detection signals D ₁ and D ₂ arrive at the same time, the logic "1'' output to the positive direction excitation current thyristor 77A via the OR circuit 80, the rotating winning member 2 is changed from a disadvantageous state to a profitable state for the player in the same manner as in the first case described above. Invert it so that

Fourthly, the fourth rotation command circuit 76D directly receives the internal winning detection signal _D1 and the rotational position detection signal _D3 , and also sends the external winning detection signal _D2 to the inverter 7.
Receive via 9B. Thus, as shown in the column of state 4 in FIG. 7, when the rotary winning member 2 is in the profit state for the player as shown in FIG. 2, if the internal winning detection signal _D1 arrives, the logic "1"'' output is generated and applied to the negative excitation current thyristor 77B to cause the negative excitation current I to flow through the coil 26. At this time, the left and right magnetic poles 21L and 21 of the electromagnet 20
R is excited to the S pole and N pole, respectively, and since the permanent magnets 18R and 18L (S and N poles) are facing each other at this time, a repulsive force is given to the rotating winning member 2 and it rotates.

On the other hand, the control circuit 75 controls the coil 26 in states 5 and 6 in FIG.
Do not apply excitation current to. Therefore, the rotating winning member 2 remains in its current state.

That is, when the rotational position detection signal D ₃ and the external winning detection signal D ₂ arrive at the same time, no excitation current flows to the coil 26, regardless of whether the internal winning detection signal D ₁ arrives. Therefore, when the rotary winning member 2 is in a profitable state for the player as shown in FIG. 2, if the external winning detection signal _D2 arrives, the rotary winning member 2 does not rotate and the player This means that the company will maintain its profit status.

In the control circuit 75 of FIG. 6, a holding circuit 8 including capacitors 81A and 81B is installed at the gates of the thyristors 77A and 77B, respectively.
2A and 82B are connected, and the logic "1" on signal is no longer given to the gate, so the logic "0"
It is assumed that the thyristors 77A and 77B can be maintained in the on state until the discharge of the capacitors 81A and 81B is completed when the voltage falls.

In the above configuration, the coil 26 of the electromagnet 20
When the positive direction current I is flowing through the electromagnet 20
The left and right magnetic poles 21L and 21R are excited to N and S poles, respectively. Therefore, as shown in FIG. 2, if the rotating winning member 2 is in a profitable state for the player, the permanent magnets 18R and 1 of the rotating winning member 2
8L is attracted by magnetic poles 21L and 21R,
Therefore, the rotary winning member 2 is attracted to the base plate 13 side, and the positioning piece 15 fits into the locking groove 16. Thus, the rotary winning member 2 is locked in such a state that the socket 6B faces upward and can receive game balls flowing down. At this time, since the permanent magnet 17 of the rotational position detector 70 is in a state facing the reed switch 71 (FIG. 2), the rotational position detection signal D ₃ has arrived at the control circuit 75 (the sixth
figure).

This state is maintained even if the exciting current I to the coil 26 stops flowing.

In such a state, the socket 6B of the variable prize winning device 1
When a game ball enters, as shown in state ₄ in FIG. occurs, and a negative excitation current I flows through the coil 26.

At this time, the polarities of the magnetic poles 21L and 21R of the electromagnet 20 are reversed, and the permanent magnets 18 facing each other are
The polarities are the same as the S and N poles of R and 18L (Fig. 2), and a repulsive force is generated between them. Therefore, the rotary winning member 2 is pushed away from the base plate 13 on the fixed shaft 14, and the locking groove 16 is pushed away from the positioning piece 1.
5 and becomes free to rotate. Therefore, the rotary winning member 2 begins to rotate due to the permanent magnet 17 serving as a weight.

When the magnets 18L and 18R eventually rotate to a position that coincides with the introduction port 30, the rotary winning member 2 continues to rotate due to inertia. So magnets 18L and 1
8R begins to generate an attractive force between the magnetic poles 21R and 21L, and continues to rotate until it reaches the state shown in FIG. 1 with the socket 6A facing upward. During this operation, the permanent magnet 17 of the rotational position detector 70 comes out of the state facing the reed switch 71, so that the control circuit 75
The rotational position detection signal _D3 cannot be obtained for
The output of the fourth rotation command circuit 76D falls to logic "0". However, the ON signal to thyristor 77B is held until the charge in capacitor 81B of holding circuit 78B is discharged.

Eventually, when the locking groove 16 of the rotating winning member 2 reaches a position where it engages with the positioning piece 15, the rotating winning member 2 is attracted in the direction approaching the base plate 13, and the locking groove 16 engages with the positioning piece 15. be stopped.

In this way, the rotary winning member 2 is reversed from a profitable state for the player as shown in FIG. 2 to a disadvantageous state for the player as shown in FIG. It is maintained as it is even after the negative direction excitation current I is no longer applied.

In this state, as shown in state 2 of FIG. 7, a game ball enters the specific winning device and an external winning detection signal _D2 is generated, or as shown in state 1, a gaming ball enters the variable winning device 1 and an internal winning is generated. Signal D ₁
occurs, or as shown in state 3, both signals D ₁
When D 2 and D ₂ occur simultaneously, a logical “1” output is generated from the rotation command circuit 76A, 76B, or 76C of the control circuit 75, and a positive excitation current I flows through the coil 26.

At this time, the polarities of the magnetic poles 21L and 21R of the electromagnet 20 are reversed, and the permanent magnets 18 facing each other are
The polarities of L and 18R are the same as the N and S poles, and a repulsive force is generated between them. Then, the rotating winning member 2 is pushed away from the base plate 13 again,
The locking groove 16 comes out of the fitted state with the positioning piece 15 and becomes in a state where it can freely rotate, and the rotating winning member 2
begins to rotate due to the permanent magnet 17 serving as a weight.

Therefore, in the same way as in the above case, the permanent magnets 18R and 18L of the rotating winning member 2 attract the magnetic poles 21L and 21R, and the locking groove 16 is inserted into the positioning piece 1.
The rotary winning member 2 rotates to a state where it is fitted with the member 5. Thus, the rotary winning member 2 returns to the profitable state for the player in FIG.

In this way, the rotary winning member 2 is configured to operate either the external specific winning device or the variable winning device 1 itself when the player in FIG. Even if the game ball enters the ball, it rotates and turns into a profit state for the player in FIG. 2.

On the other hand, when the player in FIG. 2 is in a profit state, only when a game ball enters only the variable prize winning device 1 itself, as in state 4 in FIG. The situation is reversed to a disadvantageous situation for the player in Figure 1.

Therefore, once the player takes the variable prize winning device 1 and rotates it to the profit state, the player will not be returned to the disadvantage state until he/she receives the profit. The interest in playing pachinko can be further improved.

In this embodiment, the variable winning device was explained as a so-called rotating ticket, but it is not limited to this, and a rotating winning device that can be electrically converted into a disadvantageous state and a profitable state for the player may be used. If equipped, it may be a variable winning device with two opposing winning members or a variable winning device with a door plate-shaped winning member, or an electromagnet as an electric drive source to change the state of the variable winning device. However, the present invention is not limited to this, and any device that operates electromagnetically, such as a solenoid or a motor, may be used.

<Effects of the Invention> As described above, according to the present invention, since the rotating winning member state detection means of the variable winning device detects that the rotating winning member is in the profit state, the drive control means When converting and driving the state of the rotating winning member of the variable winning device based on the specific gaming state detection signal from the specific gaming state detection signal generating means, the state of the rotating winning member can be grasped. Therefore, even if the predetermined conditions set in advance are complicated, the state of the rotary winning member can be reliably changed when, for example, a condition that makes the variable winning device in a profitable state and a condition that makes it in a disadvantageous state overlap. be able to. Furthermore, it is possible to notify the player of the conversion state of the variable prize winning device and to notify the management device of the game parlor. Therefore, it is possible to eliminate troubles between the gaming parlor and the player caused by the variable winning device continuing to be in a disadvantageous state when it should be in a profitable state. To provide a pachinko machine that allows users to play games with peace of mind.
