Description

[Detailed Description of the Invention] Purpose of the Invention (Field of Industrial Application) The present invention relates to a winning device for a pachinko machine that can change the rate of winning into a specific winning opening.

(Prior Art) Conventionally, various winning devices for pachinko machines have been devised. These winning devices activate the winning device for a moment by using the chance of a ball entering a safe hole provided separately from the winning device, and then taking that chance, the ball enters a specific winning hole provided within the winning device. In some cases, the winning device is operated (hereinafter referred to as rights generation) for a predetermined period of time. Then, the winning device continues the operation of the winning device (hereinafter referred to as right continuation) if the ball enters the specific winning hole again within the certain time, and if the ball does not enter the specific winning hole within the certain time, Stopping the operation of the winning device (hereinafter referred to as extinguishment of rights)
I'm starting to let them do it. In addition, a certain number of balls entered is predetermined, and when the number of balls entered into a specific winning hole reaches that number, the operation of the winning device is similarly stopped (hereinafter, the right is also called extinguished).

Therefore, even if the right is generated, if the ball does not enter the specified winning hole within the specified period of time, the right will not continue and will expire.On the contrary, as soon as the ball enters the specified winning hole continuously, the right will expire. Since the number of balls entered is reached, the time during which the right is in effect becomes extremely short.

In other words, if you repeatedly land the ball in the specific winning hole just before the right expires after the fixed time has elapsed, you can maximize the duration of the right. The above actions are the key points when enjoying playing with this pachinko machine, and these actions are closely related to the rate at which the ball lands in the specific winning hole during the right expiration.

(Problem to be solved by the invention) However, in the pachinko machine proposed above, the drop rate into the specific winning hole is always constant;
For example, it is not possible to change the probability in advance during the continuation of the rights, and the game tends to become monotonous.

The purpose of the present invention is to provide a winning device that can vary the game by changing the probability of winning into a specific winning hole.

b is bent rearward at both left and right walls of the housing portion 1a to form a bent portion 13c. And trajectory changing member 1
3 forms an insertion space 14 between it and the rear wall of the housing portion 1a. Further, in the trajectory changing member 13, guide surfaces 13d are formed on the upper surface of the proximal end of the support arm 13b, and the guide surfaces 13d are inclined downwardly toward the outside. An inclined surface 13e serving as a collision portion is formed which is inclined downward as it goes toward the direction.

The trajectory changing member 13 is connected to a support plate 16 on the back side of the rear wall of the accommodating portion 1a through a long hole 15 formed in the rear wall in the vertical direction. The support plate 16 is supported by the main body of the winning device 1 so as to be able to move up and down, and a long hole 16a is formed in the center of the back surface of the support plate 16 in the horizontal direction, into which an interlocking pin 17a of a cam disc 17 to be described later is inserted. It is. The interlocking pin 17a of the cam disk 17 is formed at a position eccentric from the center of the front surface, and the cam disk 17 is rotatable with its outer peripheral surface guided by the main body of the winning device 1.

On the other hand, a safe hole 28 is provided above the upper blocking member 25, and a prize ball is ejected when the ball enters the safe hole 28.

Next, the electrical configuration of the pachinko machine configured as described above will be explained.

A central processing unit 29 (hereinafter referred to as a computer) as a control device controls each of the sensors 4, 10, 1.
The detection signals from 1 and 18 are input to the storage device 30.
It operates based on a control program stored in the . Furthermore, the computer 29
The calculation result is temporarily stored in the storage device 30.

The computer 29 controls the solenoid drive circuit 31 based on the detection signal from the first detection sensor 4.
The solenoid 5 is actuated via the .

Further, the computer 29 operates the solenoid 24 via the solenoid drive circuit 32 based on the detection signal from the second detection sensor 10. Further, the number of times the ball enters the ball is displayed on the display section 27.

On the other hand, the computer 29 operates a prize ball supply device (not shown) based on the detection signal from the third detection sensor 11.

Furthermore, the computer 29 operates the motor 19 via the motor drive circuit 33 based on the detection signal from the position detection sensor 18 .

Now, the operation of the pachinko winning device 1 configured as described above will be explained.

When a pachinko ball enters the safe hole 2 shown in FIG. 1, it is detected by a switch (not shown), and the solenoid 24 that drives the movable member 22 is energized. By driving this solenoid 24, the movable member 22 reciprocates once or twice through the meshing portion 23, giving a chance for the pachinko balls to enter the housing portion 1a of the prize entry device 1. At this time, storage section 1
The pachinko ball that enters a fits into the launch hole 3 or enters the safe hole 8.

As shown in Figure 3, the pachinko ball hits the launch hole 3.
When the ball is stuck in the pachinko ball, the first detection sensor 4 detects the ball, and the solenoid 5 serving as a launching device launches the pachinko ball upward. As shown in FIG. 4, this launched pachinko ball is bounced above the trajectory changing member 13 by the inclined plate 12, and when it passes through the communication space 14 of the trajectory changing member 13 on the way of falling, it hits the collision area. slope as 13
The falling direction can be changed by hitting e. At this time, the guide surface 13d bounces the pachinko ball that hits it toward the slope 13e, thereby increasing the probability that the falling ball will hit the slope 13e. The ball bounced onto the slope 13e may enter the specific winning hole 9, or may leave the winning hole 9 and enter the safe hole 8 in front of it.
When the ball enters the safe hole 8, the movable member 22 does not rotate, and the third detection sensor 11 operates the prize ball supply device to eject the prize ball. On the other hand, when the ball enters the specific winning hole 9, the solenoid 24 is actuated by the second detection sensor 10, so the movable member 22 reciprocates for a certain period of time and a right is generated. If the ball enters the winning hole 9 again within this certain period of time, the right continues, and from this time, the movable member 22 is reciprocated for a certain period of time, and if the ball does not enter the ball again after this certain period of time, the movable member 22 reciprocates. The rotation will stop and the rights will be extinguished. Furthermore, this specific winning opening 9
The number of balls entered is displayed on the display section 27,
When the number of balls entering the winning hole 9 reaches eight times, the movable member 22 stops reciprocating rotation and the right is extinguished.

On the other hand, the trajectory changing member 13 is stopped at almost the lowest position at the beginning of the right generation, but when the right continues and the number of balls entering the specific winning hole 9 exceeds five times,
The computer 29 drives the motor 19 using a motor drive circuit 33. Therefore, the trajectory changing member 13 begins to move up and down between the lowest position and the highest position, and this operation continues until the right expires.

As shown in FIG. 6a, when the trajectory changing member 13 is at the uppermost position, most of the pachinko balls that hit the slope 13e enter the specific winning hole 9, and the trajectory changing member 13 descends. As the ball enters the winning hole 9, the probability of the ball falling into the winning hole 9 decreases, and as shown in FIG. 6b, when the trajectory changing member 13 is at the lowest position, the ball hardly enters the winning hole 9.

Therefore, in the first half of the right continuation when the trajectory changing member 9 is stopped at almost the lowest position, the pachinko balls that hit the inclined surface 13e do not enter the specific winning hole 9 very much. In the second half of the continuation of the right, in which No. 13 moves up and down between the lowest position and the highest position, the probability of a pachinko ball entering the ball is higher than in the first half.

As described above, in this embodiment, the trajectory changing member 13 can be moved up and down by the motor 19, and the trajectory changing member 13 can be moved up and down by the motor 19.
A pair of inclined surfaces 13 as collision parts formed in 3.
Since the head difference between e and the specific winning hole 9 can be changed, the falling point of the ball that hits the slope 13e changes, and the probability of falling into the specific winning hole 9 provided directly below the trajectory changing member 13 is increased. Can be changed.

In this embodiment, the probability of ball entry is changed between the first half and the second half while the right is continuing, but for example, two safe holes are provided that trigger the right to occur, and the ball enters which safe hole. It is also possible to select the probability of ball entry. Furthermore, in this embodiment, the movement of the trajectory changing member 13 is divided into a state in which it is stopped at almost the lowest position and a state in which it is moved up and down between the lowest position and the highest position. The position of the trajectory changing member 13 may be sequentially raised or lowered in accordance with the increase, or may be moved in accordance with a predetermined time instead of the number of ball hits. Further, the pair of opposing inclined surfaces 13e provided on both sides of the trajectory changing member 13 do not necessarily have to be a pair, and may be only one.

Effects of the Invention As detailed above, in the present invention, the drop rate of the specific winning hole 9 in the winning device 1 can be changed, so it is possible to change the game, which is an excellent industrial application. be effective.
