Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention provides a movable member that can be converted into a first state that is disadvantageous to a player and a second state that is advantageous to the player, and is guided by the movable member. The present invention relates to a variable winning device for a pachinko machine having a general winning opening for receiving a hit ball that has flowed into the variable winning device to generate a general prize mode and a special winning port for generating a special prize mode.

(Prior Art) Conventionally, in a pachinko machine, in order to increase the interest of the game by changing the content of the game, a number of electric prize winning devices called so-called accessory have been developed.

For example, an opening / closing wing as a movable member is provided on both sides of the variable winning device, which is convertible into a disadvantageous state for the player, for example, a first state in which a hit ball is not accepted, and a favorable state for the player, for example, a second state in which a hit ball is easily accepted. In addition, it has a special winning opening in the center of the lower part of the device, and a normal winning opening as a general winning opening that receives a hit ball that has flowed into both sides and generates a general prize mode. Although it is closed from the game area, a ball hitting a specific winning opening in the game area, that is, a game ball winning, opens and closes the opening and closing wings once or twice to communicate with the game area, at which time the game ball jumps into the device. If you win inside the special prize hole, it will be a big hit, and it will shift to a special game mode as a special prize mode, for example, a game state where a maximum of 18 times of opening and closing blades in one cycle is one cycle, and the winning rate will be large. Increased It is configured variation winning device as.

(Problems to be solved by the invention) However, as a result of the special winning opening and the normal winning openings as the general winning openings on both sides thereof being located below the opening / closing blades, in the known variable winning device, from the substrate opening. Although it has a recessed chamber toward the rear, the hit ball that is guided by the opening / closing blades and jumps into the device often directly wins the special winning opening or the normal winning opening.

In other words, there was no time to give the player the pleasure of winning a special prize or a normal prize.

Originally, the hit ball enters the inside of the recessed chamber, flows down the flow-down guide surface of the recessed chamber over time, and whether it is a special prize mode prize or a general prize mode normal prize at the destination is played. It can be said that it is desirable that the prize winners be decided after the players have fully enjoyed the fun.

In this sense, the known variable winning apparatus often lacks the interest of pachinko games because the winning destination is often decided at the moment the ball hits.

Also, forcibly ending the special game mode as the special prize mode,
In other words, the unfortunate situation that a maximum of 18 times of continuous opening and closing blades does not win the special winning opening once in one cycle is likely to occur, and even if you have a hard time generating special game mode rights, you can get the prize you want It was often not possible to get the number of balls. This point also resulted in killing the interest of pachinko games.

The present invention has been made in view of the above problems, and guides the hit ball that has been thrown into the device to the inside of the concave chamber to allow the player to enjoy the enjoyment of winning the special prize mode over time. The purpose of the present invention is to provide a variable winning device for a pachinko machine that makes it relatively easy to continue the special game mode.

(Means for Solving Problems) The present invention provides a movable member (12) that can be converted into a first state that is disadvantageous to the player and a second state that is advantageous to the player.
A general winning opening (1) that receives a hit ball guided by the movable member and flows into the variable winning device to generate a general prize mode (1
In a variable winning device of a pachinko machine having 9) and a special winning opening (20) for generating a special prize mode, a concave chamber (15) is provided in the variable winning device, and a bottom surface (21) of the concave chamber is provided. Is formed diagonally downward toward the special winning opening and the general winning opening, and extends from the front surface of the recessed chamber to the recessed chamber, and the recessed chamber is vertically moved to the first winning area (15A) and the second winning area (15B). The downflow guide shelf (23) is divided into two parts, and in the vicinity of the downflow end of the downflow guide shelf, there is a general winning opening (28) for receiving the winning balls flowing down the side portion of the downflow guide shelf, and the downflow guide. A communication port (24) for guiding the winning ball flowing down the center of the shelf to the second winning area is provided, and the action position for blocking the passage of the ball and the passage of the ball are allowed for the communication port. The distribution member (27A, 27B, 27C) that circulates between the non-acting position is configured to face from above the communication port. Than it is.

(Operation) All of the hit balls that have jumped into the apparatus by the downflow guide shelf that divides the concave chamber into the first prize area and the second prize area are vertically picked up by the downflow guide shelf. Flow down the side on the guide shelf to enter the general winning opening, or flow down the center on the flow down guide shelf toward the communication port.

If the prize ball enters the communication port, it is guided to the second prize region below and flows down the bottom of the recessed chamber to win the special prize hole or the general prize hole.

Therefore, since there is a flow of balls from the first winning area to the second winning area, it is possible to continue to give the player the expectation of winning the special winning opening during that time.

Moreover, the distribution member is made to face above this communication port, and in normal games, it is circulated between the working position which blocks the passage of the ball to the communication port and the non-working position which allows the passage of the ball. Therefore, some of the prize balls that have flowed down the center of the flow-down guide shelf cannot pass through the communication port.

That is, it is divided into those which pass through the communication port and those which cannot pass and are brought to the side portion on the downflow guide shelf.

Therefore, for the player, the prize-winning ball needs to be generated at the center of the downflow guide shelf at the timing when the sorting member is in the non-acting position where the ball can pass, which enhances the enjoyment of the pachinko game.

On the other hand, for the game store, the winning probability itself to the variable winning device can be adjusted loosely, and the enjoyment of the variable winning device itself can be enjoyed by the player.

(Embodiment) Hereinafter, the present invention will be described based on an illustrated embodiment.

In FIG. 1 and FIG. 2, 10 is a main frame of the variable winning device 1, and the main frame 10 has a mounting board 11 provided with an opening window 11A (FIG. 4) in the middle and an opening. It has two opening / closing blades 12, which are movable members arranged on both sides of the window 11A.

The mounting substrate 11 has an armor portion 11B above the opening window 11A, and has jump-in prevention plates 11C and 11D above and below the opening / closing blade 12 so as to surround the opening window 11A. Also, on the back surface of the mounting substrate 11,
In order to form the recessed chamber 15 from the opening window 11A toward the rear, the recessed chamber frame portion 13 is extended, and the first auxiliary chamber frame portion 13A is provided on the side portion thereof.
However, the second auxiliary chamber frame portion 13B is connected to the further side portion thereof.

Reference numeral 14A in the drawing is an upper plate that forms the upper surface of the concave chamber 15, and 14B is a rear plate that forms the rear surface of the concave chamber 15.

The first auxiliary chamber frame portion 13A and the second auxiliary chamber frame portion 13B of the main frame body 10 are provided with illumination lamps, colored plates, etc., respectively, and illuminate the internal space, and at the same time, inside the recessed chamber 15. Is made to appear.

This is to increase the depth of the interior space of the recessed chamber 15, the first auxiliary chamber frame portion 13A, and the second auxiliary chamber frame portion 13B.

Furthermore, the first auxiliary chamber frame portion 13A and the second auxiliary chamber frame of the main frame body 10 and the mounting substrate 11 are arranged so that the internal spaces of the first auxiliary chamber frame portion 13A and the second auxiliary chamber frame portion 13B can be visually recognized. A portion corresponding to the portion 13B is formed as the transparent portion 10A.

In this way, by providing auxiliary chambers on both sides of the recessed chamber 15 and making it visible from the front, the expansion of the opening window 11A can be prevented, and the reduction of the game area can be prevented, while expanding as if there were a large recessed chamber. It has the effect of showing it to the player.

On the armor portion 11B of the mounting board 11, the winning prize hole 16 and the number-of-rights indicator 1
7 is provided, and the second auxiliary chamber frame portion 13B on the left and right of the mounting substrate 11
General winning holes 18 are provided on the outer side. The number-of-rights indicator 17 consists of a 7-segment LED digital indicator.

On the lower part of the front surface of the mounting board 11, along the lower side of the opening window 11A, on both sides, as a general winning hole for receiving a hit ball that has been guided by a movable member and has flowed into the variable winning device, to generate a general prize mode. The regular winning openings 19 of, and the special winning openings 20 are juxtaposed in the center of these. The bottom surface of the recessed chamber 15 is composed of a recessed chamber bottom surface member 21 which is arranged to incline obliquely downward toward the special winning opening 20 and the normal winning opening 19. Below the concave chamber bottom member 21, there is provided a winning ball flow-down frame 22 (FIG. 4) for winning balls that have entered the concave chamber 15.

Inside the recessed chamber (a) Distributing prize balls In FIGS. 1 and 4, reference numeral 23 is a flow-down guide shelf provided in the recessed chamber 15, and the flow-down guide shelf 23 receives the recessed chamber 15 as the first prize. region
It functions as a partition member that is divided into 15A and the second winning area 15B.

The flow-down guide shelf 23 does not exist only inside the recessed chamber 15, but the front end portion of the flow-down guide shelf 23 projects from the recessed chamber 15 to a position near substantially the front surface of the opening / closing blade 12.

Therefore, the hit ball guided in the apparatus by the opening / closing blade 12 as the overbody member is directly below the normal winning opening 19 or the special winning opening 20 as in the case where it exists only from the opening window 11A of the mounting substrate 11. Without entering, all are picked up by the downflow guide shelf 23, and flow down toward the back of the concave chamber 15 on the upper surface of the downflow guide shelf 23.

At the center near the lower end of the flow-down guide shelf 23, a winning ball that flows down the center on the flow-down guide shelf 23, the second winning area of the concave chamber 15
A communication port 24 for leading to 15B is provided in the notch of the downflow guide shelf 23.

On the upper surface of the flow-down guide shelf 23, from the middle of this, this communication port 24
A guide recess 23A that is inclined toward is formed.

In this embodiment, a background model 25 simulating a tank is arranged inside the recessed chamber 15. The background model 25 includes a rotating disc 26 arranged in front of the interior of the concave chamber 15 and a rotating disc 26 having a surface 1
It has distribution members 27A, 27B, and 27C that imitate three missiles arranged at regular intervals along one arc.

The distribution members 27A, 27B, and 27C are above the communication port 24 formed in the vicinity of the lower end of the flow-down guide shelf 23, and allow the passage of the ball and the action position of blocking the passage of the ball with respect to the communication port. The distribution member that circulates between the non-acting position and the non-acting position is positioned so as to face from above the communication port.

In normal games, this sorting member 27A, 27B, 27C
Circulates between the “acting position” that blocks the passage of the sphere to the communication port 24 and the “non-acting position” that allows the passage of the sphere with the rotation of the rotating disk 26. The sphere that has flowed down on the guide shelf 23 is distributed to the first prize area 15A above the flow down guide shelf 23 or the second prize area 15B below.

More specifically, as shown in FIG. 5 (A), any one of the distribution members 27A, 27B, and 27C is now in the rotational position (operating position) within the lateral width of the communication port 24. It is assumed that the winning ball has flowed down into the guide recess 23A in the center of the downflow guide shelf 23. If this winning ball enters the downstream side of the distribution member 27A in the rotation direction, that is, if it enters the right side of the distribution member 27A as seen in FIG. 5 (A), it is allowed to pass through the communication port 24.
If it enters the downstream side of the rotation direction of 27A, that is, the left side of the distribution member 27A, the passage to the communication port 24 is rejected. This is because as the distribution member 27A rotates, the right side of the distribution member 27A becomes wider and the left side becomes narrower with respect to the lateral width of the communication port 24. Therefore, as long as the distribution members 27A, 27B, and 27C circulate with the rotation of the rotary disc 26, the distribution member at that time is a winning ball that has also flowed down in the center of the flow-down guide shelf 23. Depending on the rotation position of 27A, etc., the first prize area 15 above the recessed chamber 15 may exist when the prize ball is present.
When it is in A again, it is distributed to the second prize area 15B below.

In this embodiment, a guide recess 23A that is a flow path to the communication port 24 is provided in front of the communication port 24, and a raised portion 23B is provided on the upper surface of the downflow guide shelf 23 on both sides of the guide recess 23A. hand,
The flow path (guide recess 23A) to the communication port 24 and the other side flow path 23C are clearly distinguished. Therefore, the downflow guide shelf 23
When the winning ball that has flowed down the center of the is distributed to the side flow passage 23C without entering the communication port 24, the winning ball exceeds the raised portion 23B by the distribution member 27A and the side flow passage 23C.
Will be pushed to.

FIG. 5 (B) shows a rotational position (non-acting position) in which any two 27A, 27C of the sorting members 27A, 27B, 27C exist at the lateral edge of the communication port 24. In this non-acting position,
The winning ball that has flowed down into the guide recess 23A of the downflow guide shelf 23 is
All are permitted to pass through the access port 24. The appearance of this inactive position occurs three times for each rotation of the rotary disc 26. Further, when the special game mode occurs, the rotating disk 26 is stopped in a state where the sorting members 27A, 27B, 27C are in the non-acting position, and facilitates the continuation of the special game mode.

The winning ball that has passed through the communication port 24 falls inside the concave chamber 15 to the second winning region 15B below and is picked up by the concave chamber bottom member 21. Then, it flows down on the bottom member 21 of the concave chamber and is a normal winning opening on the front side.
19 or the special winning opening 20. On the other hand, in the concave chamber 15, on both sides of the communication port 24, the side flow path 23 on the flow-down guide shelf 23 is provided.
General prize opening 28 that accepts prize balls coming down C,
It is provided independently from the communication port 24. In this embodiment, the background model 25 simulating a tank has a caterpillar 25A and a fender 25B above the caterpillar 25A, and a general winning opening 28 is formed in the fender 25B. The winning ball flowing down on the side flow path 23C of the downflow guide shelf 23 is delivered to the general winning opening 28 of the fender 25B, and the first winning opening 28
Discharge hole 28A that enters the auxiliary recess chamber frame 13A and is provided on the lower surface
It goes out of the main frame 10 from (Fig. 3).

In this way, all the hit balls guided into the device by being guided by the opening / closing blades 12 flow down on the flow-down guide shelf 23, and a part thereof further flows down on the bottom surface member 21 of the recessed chamber to start normal operation. Winning hole 19
Or reach the special winning opening 20. Therefore, the hit ball stays in the recess chamber 15 for a long time, and while the hit ball flows down in the recess chamber 15,
The player can be expected to win the special winning opening 20, and the player can fully enjoy the special winning until reaching the special winning opening 20. Downflow guide shelf
When 23 does not protrude from the recessed chamber 15, the hit ball received by the opening / closing blade 12 has a higher rate of falling immediately downward, which is not enough to raise the expectation for the right generation, The contents of the game are enriched as compared with such a configuration.

(B) Reservation of prize balls In FIG. 1, FIG. 3 and FIG. 6, the general winning opening 28 in the concave chamber 15 is opened on the inner side of the concave chamber 15 in the normal game. When the special game mode occurs, the general winning opening 28 is closed to prevent the winning ball from flowing down to the general winning opening 28, and the winning ball falls within the first winning area. A storage ball control member 30 for storing is provided.

More specifically, the storage ball control member 30 has a rear surface of the concave chamber 15,
That is, it consists of an elongated plate material that penetrates two holes 29 (Fig. 3) provided in the rear plate 14B, and its rear end is U-shaped as shown in Fig. 6.
It is integrally connected by a character-shaped base portion 30A and is connected to the plunger 31A of the storage ball control solenoid 31. Energize the reservoir control solenoid 31 to return the plunger 31A Spring 3
By suctioning against 1B, the stored sphere control member 30 moves from the solid line position in FIG. 6 to the dotted line position. The solid line position is the position where the reserved ball control member 30 opens the general winning opening 28,
The dotted line position is a position where the reserved ball control member 30 closes the general winning opening 28 and prevents the winning ball from flowing down to the general winning opening 28. Therefore, when the storage ball control member 30 is in the blocking position of the dotted line, the winning ball that will flow down to the general winning opening 28,
As shown in FIG. 6, the side flow passages 23C of the flow-down guide shelf 23 are sequentially arranged.
Will be stored in one row. In this embodiment, a maximum of 3 flow-downs are blocked, and a total of 6 by the two stored-sphere control members 30.
Up to individual winning balls are stored. However, the reservoir control member
Since the recesses 30 are only located on both sides in the recessed chamber 15, a space where the winning balls can flow down is still left between the storage ball control members 30. The presence of the storage balls 32 up to a maximum of 6 changes the flow of the winning balls on the downflow guide shelf 23, so that the winning balls flow down to the central guide recess 23A by bypassing the side flow passage 23C. The probability of winning the special winning opening 20 through the contact opening 24 increases. Then, by returning the storage ball control member 30 to the open position of the solid line, all of the storage balls are the general winning opening.
Taken in 28.

In the variable winning device that does not have a movable member in the recessed chamber 15, if the probability of generating the right to win the special winning opening 20 is kept low at the beginning, it is inevitable that the continuous winning of the special winning opening 20 will occur after the right is generated. The probability is also fixed to a low level to the same extent, but by configuring the storage ball control member 30 to change from the open position to the blocking position as described above, the probability of the right being generated can be kept low while the right is generated. It is possible to increase the continuous winning probability.

(C) Prize winning number display, etc. In FIG.
There is a prize number indicator 45 consisting of 5 LEDs vertically arranged above the LED. These LED1 to LED5, LED6 to LED1
0 is a printed circuit board 45A provided on the back surface of the rear plate 14B of the recessed chamber 15.
(FIG. 3). In this embodiment, these left and right LEDs are modeled on a cannon mounted on a background model 25 tank. An illumination lamp 46 is provided in a model of a tank headlight.

The winning balls that have entered the special winning opening 20 flow out from the winning ball flow-down frame 22, are detected by the special winning detector SW3 suggested in FIG. 8, and then enter the collecting trough (not shown). The special winning balls flowing out from the winning ball flow-down frame 22 are collected together with the normal winning balls flowing out from the normal winning opening 19 in the collecting trough, and are counted by the count detector SW4 (FIG. 8) located at the lower end of the collecting trough. , Are counted without distinguishing both.

Drive Device A first drive device frame 40, to which a motor M for circulating the distribution member 27 is attached, is attached to the rear of the recessed chamber frame portion 13, and an opening / closing blade is attached to the rear of the first drive device frame 40. A second drive device frame 50 to which a first solenoid SOL1 for opening and closing 12 is attached is attached.

(A) Driving of distribution member In FIGS. 3 and 4, on the back surface of the rear plate 14B of the concave chamber 15, two gears meshed with each other for rotating the rotary disk 26 of the distribution member 27. 33 and 34 are arranged, the shaft of the gear 33 is connected to the rotary shaft of the rotary disc 26, and the shaft 34A of the gear 34 is connected to the output shaft of the motor M provided in the first drive device frame 40.
Therefore, by energizing the motor M, the rotary disk 26 rotates via the gears 33 and 34, and the distribution member 27 circulates in one direction. Since it is possible to detect that the distributing member 27 is in the non-acting position as shown in FIG. 5 (B) and stop it at the non-acting position, the shaft 34A of the gear 34 has three
A position detection disk 35 having one notch 35A is fixed.
The three notches 35A are respectively provided at the rotational positions where the sorting member 27 is in the non-acting position as shown in FIG. 5 (B). Reference numeral 36 is a photo interrupter as a position detector that detects the notch 35A of the position detection disk 35, and is attached to a support member 37 protruding from the rear plate 14B of the recess chamber 15. The position detector 36 determines that the sorting member 27 is in the non-acting position of FIG. 5B when the light blocking is released by the notch 35A of the position detecting disk 35.

(B) Operation of the open / close blade In FIG. 3, the rotary shaft 12A of the open / close blade 12 is supported by bearings 38 that extend long rearward through both sides of the recessed chamber 15 and the rear plate 14B. At the rear end of the rotary shaft 12A, the opening / closing blade 12
Operation lever 3 with pin 39A implanted to open and close
9 is fixed. The pin 39A of the operating lever 39 is the first
Drive lever 52 fixed to plunger 51 of solenoid SOL1
Is loosely fitted in the engagement hole 52A.

Normally, the plunger 51 and the drive lever 52 are in the lower position as shown in FIG. 3 by the action of their own weight and the return springs 51A and 53, and at this time, the left and right opening / closing blades 12 are as shown in FIG. It remains in the first state where it does not accept hits. The return springs 51A and 5A are driven by the force of the first solenoid SOL1.
When pulled up against 3, the operating lever 39 shown in FIG. 3 rotates from the outside to the inside, and the opening / closing blade 12 does not accept the hit ball.
The state is changed to the second state in which the hit ball is easily received.

In FIG. 3, in addition to the motor M and the storage ball control solenoid 31, the second solenoid SOL2 is provided in the first drive device frame 40.
Is provided. This second solenoid SOL2 is a plunger 51 of the first solenoid SOL1 provided in the second drive device frame 50.
This is for limiting the stroke, and therefore the opening of the opening / closing blade 12, to about half. In this embodiment, since the second solenoid SOL2 is collectively provided on the same first drive device frame 40 together with the motor M and the stored ball control solenoid 31, the stored ball control solenoid 31 is attached to one side from the center, As a result, the second solenoid SOL2 is vertically mounted in the space created on the other side, and the motor M is connected to the second solenoid SOL2.
It is provided below the stored-ball control solenoid 31.

In FIG. 7, a support member 54 is provided on the front surface of the second drive device frame 50.
The control claw 55 is attached by. The control claw 55 is a support
It is rotatably supported about a shaft 56 provided laterally between two ears 54A of 54, and has an operating lever 57 extending obliquely upward from the shaft 56 portion in a dogleg shape. . A rod 57A extends laterally at a right angle from the tip of the operating lever 57, and the tip of the rod 57A is exactly the lower end of the plunger 41 of the second solenoid SOL2 attached to the first drive device frame 40. Is in contact with the lower surface of a disc 41A provided at the lower end of the plunger 41. The rod 57A of the operating lever 57 is constantly pulled upward by the spring 58 within the movement range of the plunger 41 of the second solenoid SOL2.

In the normal state shown in FIG. 7, the control pawl 55 is on the front surface side of the second drive device frame 50, and the stroke of the plunger 51 of the first solenoid SOL1 on the rear surface side of the second drive device frame 50. Has nothing to do with. However, when the second solenoid SOL2 is urged, the plunger 41 is attracted and the plunger 41 moves downward against the return spring 58. The control claw 55 rotates counterclockwise around the shaft 56 in FIG. 7 via the operation lever 57, and projects rearward from the opening 50A provided in the second drive device frame 50. The control claw 55 is restricted from rotating by abutting on the tongue 54B of the support body which also projects from the opening 50A. When the control claw 55 reaches the limit position and projects to the back surface of the second drive device frame 50, the stroke of the plunger 51 of the first solenoid SOL1 is restricted to about half. That is, when the plunger 51 of the first solenoid SOL1 is attracted, the drive lever 52 fixed to the plunger 51 also tries to move upward, but the upper end of the drive lever 52 comes into contact with the lower surface of the control pawl 55 and moves. Is blocked by the drive lever 52
Cannot move above the control claw 55.

Thus, the stroke of the plunger 51 of the first solenoid SOL1, and thus the opening degree of the opening / closing blade 12, is limited to about half.

Application Example FIG. 8 shows an example of a pachinko machine to which the variable winning device 1 is applied.

As described above, the special prize detector SW3 is provided in the special prize opening 20 of the variable prize device 1, and the normal prize hole 19, the general prize hole 28 and the special prize are provided in the prize ball collecting gutter for the variable prize device 1. A count detector SW4 for counting the winning balls from the mouth 20 without distinguishing them is provided.

Control Device The control operation of the pachinko machine will be described below with reference to the circuit diagram of FIG. 9 and the timing diagram of FIG.

Reference numeral 70 is a reference time generation unit having a clock oscillation circuit 71 and a counter circuit 72. The counter circuit 72 includes a multi-stage frequency divider for the oscillation clock and a logic circuit connected to the frequency divider.
It produces different types of time signals T0 to T6. T0 is 0.8 seconds, T
5 is a time signal with a repeating period of 0.2 seconds, T6 is 0.25 seconds, T1
1.3 seconds later, T2 3.2 seconds later, T4 3.0 seconds later, T3 31.
It is a time signal that rises after 0 seconds. However, T6 is independently generated regardless of the reset system of the count circuit 72.

Next, the operation will be described.

Control of normal game state Normally, the open / close wing 12 is in a closed state (first state) that does not accept hitting balls.
And the variable winning device 1 is closed to the game ball. However, when a hit ball is won in the specific winning openings 8 and 9, the first solenoid SOL1 is actuated in the following manner to cause the opening / closing blade 12 not to accept the hit ball and the second state in which the hit ball easily projects from the first state. Is converted once or twice.

(A) Winning to the first specific winning opening The first operation detection switch SW1 after winning the specific winning opening 8, 8
When is turned on (point a in FIG. 10), the flip-flop FF1 is set via the waveform shaping circuit 73, and its output terminal Q is inverted to H level and L level. The output of the AND gate 78 which has been at the H level until then disappears, the reset state of the counter circuit 72 is released via the OR gate 79, and the counting operation of the counter in the counter circuit 72 is started.

An output pulse (T5) is generated at the output terminal Q5 of the counter circuit 72, and the lamp of the background model 25 is passed through the lamp drive circuit 80.
46 etc. are lit with a blinking cycle of 0.2 seconds. Further, when 0.8 seconds has elapsed after the start of counting (point b in FIG. 10), an output pulse (T0) is generated at the output terminal Q0 of the counter circuit 72, and the two-input AND gate 81 opened by the output of the flip-flop FF3. , OR gate 82 is sent to the solenoid drive circuit 83 as an opening / closing blade actuation signal S0, and the first solenoid SOL1 is energized. The open / close blade operation signal S0 is for the following reason.
The width is shortened to 0.5 seconds and the opening / closing blade 12 is opened and closed once.

That is, 1.3 seconds after the start of counting (point c in FIG. 10),
An output pulse (T1) is generated at the output terminal Q1 of the counter circuit 72 and is applied to the reset terminal of the flip-flop FF1 via the two-input AND gate 84 and OR gate 85 opened by the output of the flip-flop FF2 and resets it. The initial state. When the flip-flop FF1 is reset, the output of the flip-flop FF1 returns to the H level, the output of the AND gate 78 goes to the H level, and the counter circuit 72 returns to the reset state.

On the other hand, when the flip-flop FF1 is reset, the flip-flop is passed through the rising differentiating circuit 74 and the OR gate 75.
When FF6 is set and its output terminal becomes L level, the reset state of the valid time creation timer 76 composed of a counter is released, and the timer 76 starts the time counting operation for treating the winning ball as valid. . The flip-flop FF6 is returned to the reset state via the OR gate 77 when the timer time is up.

The opening / closing operation of the opening / closing blade 12 is performed by the second solenoid SOL2.
Is done by about half the stroke. That is, AND
The gate 87 is established, and the output of the gate 87 causes the second solenoid SOL2 to be 1. through the AND gate 89 and the solenoid drive circuit 90.
Energized for 3 seconds. Therefore, the control claw 55 (FIG. 7) projects to control the movement of the drive lever 52, and the stroke thereof, and accordingly the opening degree of the opening / closing blade 12, is halved.

(B) Winning in the second specific winning opening The second specific winning opening 9 is won, and the second operation detection switch SW
When 2 is operated, the opening / closing blade 12 is opened / closed only twice under the control described below.

First, when the second operation detection switch SW2 operates (point d in FIG. 10), the flip-flop FF is passed through the waveform shaping circuit 86.
2 is set. The flip-flop FF1 is also set by the Q output of the flip-flop FF2, and the counter circuit 7
The reset state of 2 is released. Therefore, the process in which the opening / closing blade operating signal is generated 0.8 seconds after the start of counting and the opening / closing blade 12 opens and closes once is the same as in the case of winning the first specific winning opening.

However, in the case of winning the second specific winning opening, the output of the flip-flop FF2 is at the L level, so a two-input AND
Gate 84 is closed. Therefore, even if the output pulse (T1) is generated at the output terminal Q1 of the counter circuit 72 after the lapse of 1.3 seconds, the two-input AND gate 84 does not accept this. Therefore, the counting of the counter circuit 72 progresses, and an output pulse (T2) is generated at the output terminal Q2 of the counter circuit 72 3.2 seconds after the counting starts (point e in FIG. 10). This pulse is
It is added to the reset input terminal R of the flip-flops FF1 and FF2 through the OR gate 85, and both flip-flops FF1 and FF2 are added.
To reset. Since the outputs of both flip-flops FF1 and FF2 return to the H level, the output of the AND gate 78 goes to the H level, and the counter circuit 72 returns to the reset state.

Until the counter circuit 72 returns to the reset state, the second pulse is generated at the output terminal Q0 of the counter circuit 72, and the first solenoid SOL1 becomes 0.8 through the two-input AND gate 81 and the solenoid drive circuit 83. Energized for a second. Therefore, the opening / closing blade 12 performs opening / closing operation twice in total.

(C) Simultaneous winning of the first and second specific winning openings Simultaneous winning of the first and second specific winning openings 8 and 9,
When the flip-flop FF2 is also set while the flip-flop FF1 is set, the AND gate 87 is not established and the AND gate 89 is prohibited. Therefore, the second
The solenoid SOL2 is not energized and the control pawl 55 (Fig. 7) does not act as a blocking. Therefore, the opening / closing blade 12 is independently the second
When the specific winning opening 9 is won, the opening / closing operation is performed twice by the same full width stroke.

(D) Blinking the LED Under normal gaming conditions, the flip-flop FF3 is reset, so its output is AND gate 111 and AND
Gate 113 is open. Therefore, the counter circuit 72
Pulse T6 (independent of reset system) is AND gate 1
It is output from 13 and drives the even numbered LED of the winning number display 45 through the OR gate 114 while blinking, while the inverter 1
The pulse inverted by 10 is output from the AND gate 111, and the odd-numbered LEDs are driven to blink via the OR gate 112. That is, the winning number display 45 functions as a decorative lamp in the normal gaming state.

Special mode Conversion to game state During the period when the opening / closing blade 12 is performing one or two opening / closing operations as described above, a ball that wins with the opening / closing blade as a guide is a special winning of the variable winning device 1. When the player wins in the mouth 20 and is detected by the special prize detector SW3, the opening / closing operation is continuously performed up to 18 times. In order to convert to this special mode game state, in the circuit of FIG. 9, it is necessary to turn on the special winning award detector SW3 while the AND gate 92 is opened by the output from the OR gate 93. To be more precise, the AND gate 92 is the Q output of the flip-flop FF1 provided through the OR gate 93 or the flip-flop FF1.
Is opened by the Q output of the flip-flop FF6 after the inversion of, and the special prize detector SW3 is O
It is necessary to do N.

(A) Start of wait time Now, when the special winning award detector SW3 is turned on (f in FIG. 10).
Point), a pulse is applied to the AND gate 92 via the waveform shaping circuit 91. AND gate 92 is now open by the Q output of flip-flop FF1 or flip-flop FF6. Therefore, the pulse enters the flip-flop FF3 through the AND gate 92 to set it,
The Q output of the flip-flop FF3 becomes H level and the output becomes L level. At this time, the same pulse once sets the flip-flop FF6 via the OR gate 77, the counter circuit 72 via the OR gate 79, and the flip-flop FF5 via the OR gate 95 to the initial state.

The flip-flop FF3 is set and its output is inverted to the L level, whereby the reset state of the counter circuit 72, the flip-flops FF4, FF5, the number-of-rights counter 103, and the winning number counter 108 is released. Counter circuit 7
2 starts its counting function and each flip-flop FF4, FF
5 is in a state in which it expects that a pulse will be sent from the counter circuit 72. That is, the "wait time" of 3.0 seconds described later starts. The AND gates 111 and 113 are prohibited by the output of the flip-flop FF3 dropping to the L level, and the winning number display 45 returns to its original function.

(B) Stopping the distribution member 27 The distribution member 27 stops at the non-acting position in FIG. 5 (B) as follows.

Normally, the distribution member 27 of the background model 25 circulates between the operating position and the non-operating position, and the position detector 36, which is a motor switch, repeats ON / OFF. Then, since the AND gate 61 having the flip-flop FF3 and the Q output of the flip-flop FF3 as two inputs is not established and the AND gate 62 is prohibited, the AND gate from the position detector 36 through the waveform shaping circuit 60. Input applied to 62 is ignored.

However, the special prize detector SW3 turns on and the flip-flop F
When F3 is set (point f in Fig. 10), at that point, 3
When the binary counter 63 is released from the reset state, AND
The output of the gate 61 becomes H level. Therefore, at the same time as converting to the special game mode, the AND gate 62 is established, and the pulse from the position detector 36 is shaped by the waveform shaping circuit 60 and the AND gate 6.
It is input to the ternary counter 63 through 2 and counted. When a total of three pulses from the position detector 36 are input (point g in FIG. 10), an output is generated in the ternary counter 63, and the motor that has been rotating up to that point is output via the motor drive circuit 64. Stop M. The stop position of the motor M is determined by the position detector 36.
Is the position where the cutout 35A was detected and turned OFF.
The position where 27 came to the non-acting position coincides.

In this way, the reason why the motor M is stopped after waiting for the position detector 36 to detect the notch 35A three times is that the special prize detector SW3 for the sorting member 27 that is constantly rotating.
This is because the time of turning ON is different each time, and the instability of the stopping operation seen from the player is eliminated. Therefore, depending on the circumstances, the motor M can be stopped by the first detection of the notch 35A.

When the distribution member 27 of the background model 25 completes the operation of shifting to the non-acting position and standing still during the wait time, the hitting balls picked up by the flow-down guide shelf 23 of the concave chamber 15 after that are distributed to the distribution member. Than when 27 is spinning
It is much easier to enter the communication port 24. Therefore, the probability of winning in the special winning opening 20 is increased by advancing from the first winning area 15A in the concave chamber 15 to the second winning area 15B.

Since the number-of-rights indicator 17 is still the first time, the right-number counter 103 displays "1".

(C) Temporary prohibition of opening / closing operation During the waiting time, the opening / closing operation of the opening / closing blade 12 is temporarily prohibited. This is because the AND gate 97 is prohibited by the Q output of the flip-flop FF5.

(D) End of wait time When 3.0 seconds have elapsed after the start of counting, a pulse (T4) is generated at the output terminal Q4 of the counter circuit 72, and this pulse is input to the clock input terminal of the flip-flop FF5, FF5 is set. That is, the Q output of the flip-flop FF5 is switched to the H level and the output is switched to the L level. AND gate by the Q output of flip-flop FF5
97 is opened. The pulse generated at the output terminal Q0 of the counter circuit 72 is inverted by the inverter 96, and the inverted signal is applied to the solenoid drive circuit 83 through the AND gate 97. As a result, the continuous opening / closing operation of the opening / closing blade 12 is started for the first time.

(E) Actuation of reservoir control member When the Q output of flip-flop FF5 becomes H level (point h in FIG. 10), reservoir control solenoid 31 is energized via AND gate 99 and drive circuit 100. To be done. Therefore, the stored-ball control member 30 of the background model 25 changes from the retracted position shown by the solid line in FIG. 6 to the projected position shown by the dotted line in FIG.

The reset state of the winning number counter 108 is released via the OR gate 106 when the output of the flip-flop FF5 falls to the L level. Also, flip-flop FF
5 Q output through AND gate 94 and OR gate 93
AND gate 92 is also opened.

Special mode game state control After conversion to the above special mode game state, the opening and closing wings 12 are at maximum
Open and close 18 times. Here, "maximum" 18 times is written as 18 times is a unit cycle of a special mode game, one cycle, and during this cycle, if the special winning opening 20 is further won, even if the opening / closing blade 12 This is because the cycle is interrupted and the first cycle of the next new cycle is started even before the 18 times of opening / closing operations have been completed.

(B) Operation before update When the wait time of 3.0 seconds has elapsed as described above (first
Occurs at the output terminal Q0 of the counter circuit 72.
The pulse every 0.8 seconds is inverted by the inverter 96, applied to the solenoid drive circuit 83 through the AND gate 97. The first solenoid SOL1 is energized for each pulse of the inversion signal, and the opening / closing blade 12 repeats a maximum of 18 continuous opening / closing operations in the first cycle.

Storage of Spheres by Storage Ball Control Member The storage ball control member 30 of the background model 25 is in the projecting position shown by the dotted line in FIG. 6 until four winning balls are detected as described later.

As a result of the storage sphere control member 30 being in the projecting position, each of the storage sphere control members 30 of the side channel 23C on one side can store three spheres, and the storage sphere control members 30 on both sides can store up to six spheres. Become. The existence of the storage balls stored on both sides of the recessed chamber 15 means that the winning balls after that are guided by these storage balls, and the downward movement of the balls in the first winning area 15A of the recessed chamber 15 is It works to direct to the contact port 24 of. Since the distribution member 27 is stopped in the non-acting position, they all enter the second winning area through the communication port 24. The ball passing through the communication port 24 flows down on the bottom member 21 of the recessed chamber, and the normal winning hole 19 or the special winning hole
You will be awarded one of the 20 prizes. Therefore, compared to the case where the storage ball control member 30 is in the retracted position, the special winning opening is far more.
Probability of winning 20 is improved, and continuous operation is promised by cycle update.

In the conventional variable winning device that does not have such a prize probability changing member, if the probability of generating the right to win the special winning opening 20 is first held low, the special winning opening 20 will inevitably continue after the right is generated. The odds of winning are fixed at a low level. However, as described above, if the distribution member 27 that is a movable body and the storage ball control member 30 are provided in the recessed chamber 15 and appropriately converted, the probability of the right being generated can be kept low and the continuous winning probability after the right is generated. Can be much higher than before.

Displaying the number of winning prizes While performing the above-mentioned opening / closing operation, many game balls will win the variable winning device 1 through the opening / closing wings 12. The total of the winning balls is counted by the count switch SW4, and it is checked whether it is within a predetermined number. More specifically, regardless of whether the winning ball that has entered the variable winning device 1 is a winning ball from the normal winning hole 19 or a special winning hole 20, the count on the back surface of the game board. Collected in switch SW4 and turn on the count switch.

Each time the count switch SW4 is turned on, a pulse is input to the winning number counter 108 through the waveform shaping circuit 107.
The winning number counter 108 includes an OR gate 112 or an OR gate 114.
Through, the lamps LED1 to LED9 of the winning number indicator 45 are sequentially turned on. The pulse from the waveform shaping circuit 107 is also applied to the sound effect generator 115 and causes the speaker 116 to generate an artificial sound.

Operation in the latter half of one cycle When the number of winning prizes reaches the number obtained by subtracting the maximum number of stored balls from the predetermined number, here 4 (point i in Fig. 10), the winning number counter
The Q3 output (fourth) of 108 becomes the H level and is input to the flip-flop FF4 as a first half end signal to set the flip-flop FF4.

The Q output of the flip-flop FF4 inhibits the AND gate 99 via the inverter 98, and the storage ball control solenoid 3
1 is turned off. The stored sphere control member 30 returns from the projected position to the retracted position and releases the sphere that has been stored until then. As a result, the storage balls 32 (FIG. 6) stored in the side flow passage 23C of the downflow guide shelf 23, up to a maximum of six, are placed in the recessed chamber 15 from the side flow passage 23C. It is taken in by and is counted by the count switch SW.

As described above, the probability of winning the special winning opening 20 is increased by projecting the storage ball control member 30 and storing the winning balls until the number of winning balls reaches four in one cycle. , The chance of continuation can be increased.

The sound effect generator 115 receives a pulse from the count detector SW4 and causes the speaker 116 to generate a winning effect sound each time.

(B) Cycle renewal Under the constraint of the total number of winning balls of up to 10 coins that occur in the above-mentioned one cycle, and before the above-mentioned 18 times of opening / closing operations are completed, fortunately, the special winning opening 20 If there is a winning ball to
Updated to a new cycle. If the special prize detector SW3 performs the detection operation again during this new cycle, this cycle is updated to the next cycle by the same operation as described above. Otherwise, the prize number counter 108 outputs the pulse number "10". At the time of counting, the circuit returns to the initial state accompanying the end of one cycle.

Fortunately, during the first cycle, the special prize detector SW
When 3 is turned on, the counter circuit 72, the flip-flop FF5, and the winning number counter 108 are once returned to the initial state by the pulse generated at the AND gate 92 at this time,
Enter a new wait time.

By resetting the flip-flop FF5, the opening / closing operation of the opening / closing blades is temporarily prohibited, the distribution member 27 is stopped at the non-acting position, and the like at the same time as the transition to the special game state in the middle. Further, the pulse generated in the AND gate 92 is added to the right counter 103, and the display content of the right display 17 is incremented by +1.
And set it to "2". As a result, the first cycle is updated to the second cycle, and the display content of the right count display 17 indicates the number of times the right has been exercised.

This is the same when the special winning opening 20 is won again in the transition to the second cycle, and the same operation is repeated. At that time, each re-update point, that is, a break of each cycle is clearly perceived by the player by the wait time in which the opening / closing blade 12 is closed for 3.0 seconds. In addition, special prize detector SW3
The right number counter 103 immediately advances its contents at the same time as the cycle is updated every time the detection operation is performed.

Fortunately, in the case of updating to the 8th time, which is the final cycle, by performing the opening and closing operation of 18 times promised in the cycle, or by generating 10 winning balls in total,
The special mode game state is completed.

That is, when the special winning opening 20 is won in the middle of the seventh cycle, the number-of-rights counter 103 indicates "8" indicating the final cycle.
Turns into. At the same time, the Q3 output terminal of the right counter 103 becomes H level, the output of the inverter 105 drops to L level, and the AND gate 92 is prohibited. Therefore, in the eighth cycle (final cycle) that is currently in progress, the AND gate 92 does not accept the ON signal of the special prize detector SW3 thereafter.

When a total of 18 opening / closing operations promised in the eighth cycle are performed, the counter circuit 72 determines that when the total 18 opening / closing operations are completed, or more accurately, 31.0 seconds have elapsed after the start of counting, A pulse (T3) is generated at its output terminal Q3. Also, the total
If 10 winning balls are generated, the winning number counter 10
A termination signal is generated at the overflow terminal of 8. These pulses or signals reset the flip-flop FF3 through the OR gate 109.

When the output of the flip-flop FF3 returns to the H level, the counter circuit 72, the flip-flops FF4 and FF5, the right number counter 103, and the winning number counter 108 are reset. Also, the output of this flip-flop FF3
The ND gate 125 is opened. Therefore, the number-of-rights indicator 17 returns to "0", and the LED of the winning number indicator 45 returns to the normal state in which it is blinked by the pulse T6 of 0.25 seconds from the clock generator 71. Further, when the ternary counter 63 is reset, the prohibition command of the motor drive circuit 64 is released and the motor M is started.

Thus, the entire circuit system is returned to the initial state, and the pachinko machine is changed from the special mode game state to the normal game state.

Forcibly switching to the normal game state Unfortunately, if one cycle in the middle ends without being updated, that is, 18 opening / closing operations in total with 3.0 seconds as one opening / closing operation end In this case (point k in FIG. 10), a pulse is generated at the output terminal Q6 of the counter circuit 72 when 31.0 seconds have elapsed after the counter circuit 72 started counting, and as described above, the entire circuit system is Is returned to the initial state, the special mode game state is forcibly released, and returns to the normal game state. Therefore, thereafter, again, the first and second specific winning openings 8, 9
Only after a series of operations from winning the prize to the special mode game state can be achieved. This disadvantageous situation for the player occurs because there is no winning in the special winning opening 20 after that in one cycle in which the above 18 times are set as one unit.

On the other hand, while performing the opening and closing operation, when a large number of game balls enter the variable winning device 1 through the opening and closing wings 12, and the total number of the winning balls reaches 10 (point j in FIG. 10). The content of the winning number counter 108 becomes “10”, an end signal is generated at the overflow output terminal, and the flip-flop FF3 is reset through the OR gate 109. Therefore, the special mode game state is forcibly released.

(Effects of the Invention) As described above, in the present invention, all the hit balls that have jumped into the device are picked up by the downflow guide shelf and flow down the side portion on the downflow guide shelf to become the general winning opening. Enter, or flow down the center of the downflow guide shelf toward the communication port, and if the winning ball enters the communication port, it will be guided to the second prize area below and flow down the bottom of the recessed chamber, where Further again, there is a possibility of winning in the general winning opening or the special winning opening. Therefore, the first
During the relatively long sphere flow-down period from the winning area to the second winning area, it is possible to continue to give the player an expectation of winning at the special winning opening, thereby enhancing the fun of the game.

Also, in normal games, whether or not it can pass through this communication port is determined by whether the distribution member facing above is in the operating position or the non-operating position, and it is not constant, but the communication port. Since it is divided into those that pass through and those that can not pass and are brought to the side on the downflow guide shelf,
For the player, it is necessary to generate a winning ball in the center of the downflow guide shelf at the timing when the sorting member comes to a non-acting position that allows the ball to pass, and it requires a technique there, which makes the pachinko game more interesting. To be

Further, since the distribution member of the present invention is located above the communication port formed in the flow-down plan shelf that divides the concave chamber into upper and lower parts, the player can move the distribution member, that is, It is easy to visually recognize the timing when the ball reaches the non-acting position that allows passage of the ball, and you can hone your skill.
