Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention relates to a variable prize device for a gaming machine having a movable member that can be converted into a first state disadvantageous to a player and a second state advantageous to a player. It is about.

(Prior Art) The movable member of this type of variable prize winning device guides a game ball flowing down on the game board surface into the variable prize winning device or refuses to guide the game ball depending on its conversion state.

In the variable winning device, there is a concave chamber having a depth in the direction of the back of the game board and designed to play the game ball, a game ball flowing down through the concave chamber, and a movable member passing through the concave chamber. In addition, a continuous winning opening and a general winning opening for inviting a game ball falling directly to a prize are arranged.

The movable member is generally on the front side of such a concave chamber,
It is arranged above the continuous winning opening and the general winning opening.

(Problems to be Solved by the Invention) The movable member is the first stage of introducing a game ball into the variable prize winning device. Doing is one of the real pleasures of the game, and it is a pleasure that the player pays attention to.

However, in the conventional movable member, since the movable member itself is given only a function of merely introducing the game ball,
Since many of the game balls guided to the movable member go straight in the direction of introduction, the number of balls traveling in the direction crossing the front of the concave chamber increases.

For this reason, a relatively large number of game balls fall without passing through the recessed room, and suddenly reach the final scene as to whether or not to win the continuous winning opening, and there is a remarkable lack of interest.

An object of the present invention is to solve such a problem and to provide a variable winning prize device with a rich interest.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a movable member (12) which can be converted into a first state disadvantageous to a player and a second state advantageous to a player. The variable winning device (1) of a gaming machine having a concave chamber (20) into which a game ball received by the movable member flows, and a continuous winning port (29) and a general winning port (28). The member has a configuration in which a guide portion (36) for guiding a game ball toward the concave chamber is provided on a game ball guide surface of the movable member.

(Operation) The guide ball provided on the game ball guide surface of the movable member guides the game ball flowing in while being guided by the movable member into the concave room.

(Embodiment) Hereinafter, the present invention will be described based on an embodiment shown in the drawings, taking a pachinko machine as an example of a game machine 8 and an example.

In FIG. 1 and FIG.
10, the main drive unit frame 30 and the auxiliary drive unit frame 50 are assembled.

Board Frame In FIGS. 1 and 2, the board frame 10 includes a mounting board 11 having a vertically elongated opening window 11A and a armor portion 11B, and an opening window 11.
A with an opening and closing wing 12 as a movable member provided on both sides of A,
On the back surface of the substrate 11, a concave chamber case 1 is formed so as to surround the opening window 11A.
With 3.

In the concave case 13, a main concave room 20 is formed continuously and rearwardly of the opening window 11A, and auxiliary concave rooms 24 are formed on both left and right sides of the main concave room 20.

As shown in FIG. 5, a boundary between the main recessed chamber 20 and the auxiliary recessed chamber 24 is formed by a partition plate 14 extending rearward from both side edges of the opening window 11A of the mounting board 11, and a bearing in the recessed chamber case 13. A partition plate 15 erected to support 12B is connected vertically in a single panel.

In this case, when viewed as a whole connected partition plate, the notches 14A and 15A remain at the upper rear portion (beyond the partition plate 14) and the lower front portion of the bearing 12B, and the cutaway portions 14A and 15A are inserted through the notches 14A and 15A. Both chambers are communicated with the main concave chamber 20 and the auxiliary concave chamber 24 so that the ball can freely flow.

The cutouts 14A and 15A are provided in the arms 44 of the background model 40 described later.
Function as an insertion hole that passes through the main concave chamber 20 to the auxiliary concave chamber 24 and further from the auxiliary concave chamber 24 to the main concave chamber 20.

(A) Movable Member The blade axis 12A of each open / close wing 12 as a movable member is supported by a partition plate 15 of the concave chamber case 13, that is, a bearing 12B extending along the side wall of the main concave chamber 20, An arm 16 is fixed to the rear end of the blade shaft 12A.
It is loosely fitted into a hole 32 provided in a control plate 31 of the device 30.

Accordingly, when the control plate 31 is pulled up by the force of the electromagnetic solenoid SOL1 against the spring 31A, the opening / closing lever 14 pivots from the inside to the outside in FIG.
12A rotates, and the opening / closing wing 12 moves from a first state disadvantageous to the player, for example, from a closed state shown in FIG. 3 (A) to a second state advantageous to the player, for example, as shown in FIG. 3 (B). To an open state.

The former is a non-operation state in which the player does not accept a hit ball which is extremely disadvantageous to the player, and the latter is an operation state in which the player easily accepts a hit ball which is advantageous to the player.

The opening / closing wing 12 as a movable member guides a game ball, that is, a game ball guide surface which hits the surface of the movable member, hits the tip of the upper surface of the wing when viewed in an open state as shown in FIG. A locking portion 35 is provided, and a hitting guide portion 36 is provided at the lower end of the upper surface of the wing as a guiding portion for guiding a hitting ball flowing down the upper surface of the wing toward the concave chamber 20.

Since the conventional opening / closing wing 12 has only a flat upper surface, a prize winning area formed above the opening / closing wing 12 when converted into an operation state in which a hit ball can be easily received as shown in FIG. However, there is an inconvenience that the hit ball spills even if it hits the ball.

The hit ball locking portion 35 on the tip end side of the opening / closing wing 12 is formed in view of such inconvenience, and is formed with a step so that the hit ball on the wing does not spill.

On the other hand, a ball guiding portion as a guiding portion on the lower end side of the opening / closing wing 12
36, in this embodiment, the hit ball that has flowed down the wing upper surface in the longitudinal direction is not dropped as it is, but is oblique to the downflow direction so that the downflow direction changes toward the back of the main concave chamber 20. In order to have a guide surface that closes and closes, it is formed so as to be raised above the surface of the open / close wing 12 to form a step.

As described above, guiding the hit ball received by the movable member to the rear of the concave chamber is extremely important for such a variable winning device.

Because of this, a plurality of prize areas after being received by the opening and closing wing 12 as a movable member, that is, a normal prize port 28 as a general prize area as a general prize area, and a special prize area for generating a special game state Of the special prize opening 29 as a special prize area in which the time until a prize is won in any of the prize areas and the flow length can be substantially extended, and a special game state extremely advantageous to the player is generated. This is because it is possible to increase the sense of expectation for winning of the hit ball, that is, winning in the special winning opening 29 as a continuous winning opening.

The hit ball locking portion 35 and the hit ball guiding portion 36 do not act on all hit balls that win the variable prize winning device 1, and differ depending on in what state the opening / closing wing 12 receives a hit ball.

Therefore, the opening / closing wing having the hitting portion 35 and the hitting guide portion 36
Even with 12, it is possible to balance the profit between the game store and the player.

As the movable member, the open / close wing type is shown in this embodiment, but a slide type or a so-called attacker type may be used. The guide portion 36 can be provided. (B) Number of rights indicator and winning number indicator At the lower part of the front surface of the mounting board 11, a U-shaped lower receiving frame 17 surrounding the lower side surface of the opening window 11A, and a partition wall 17A standing upright on the bottom surface. The space is partitioned by the front decorative plate 18, and a normal winning opening 28 and a special winning opening 29 are provided.

The tops of the two partition walls 17A are composed of adjustment pieces superimposed on the partition wall body with an adhesive so that fine adjustment of the winning probability of the normal winning opening 28 and the special winning opening 29 can be performed after assembly. I have to.

Five LEDs are mounted on a lower back surface of the front decorative plate 18 by a printed board so as to be positioned below the lower receiving frame 17 (see FIG. 5).

The central 19A of these LEDs is larger in diameter than the others and functions as a continuous indicator. A total of four LEDs 1 to 4 arranged on each side of the LED 19A constitute a right count display 19.

The number of rights is up to eight times, whereas half of the four LED's are in the normal lighting state for the number of rights 1 to 4 and blinking for the number of rights 5 to 8. This is because the number of display devices is reduced by displaying them.

In the concave chamber case 13, the bottom surface 21 of the main concave chamber 20 faces the winning openings 28 and 29 in a forward inclined state, and five LEs from the lower surface thereof.
The light of D is transmitted, and the winning number is displayed on the bottom surface 21.

The LEDs serving as the winning number display lamps 23 are supported on the printed circuit board 22 in a staggered manner, and both ends of the printed circuit board 22 are screwed to the bottom surface 21 of the main concave chamber 20.

The display of the winning number on the flowing bottom surface 21 and the display of the right count and the continuous display on the lower front decorative plate 18 have the following significance.

That is, in the case of the player at the time of occurrence of the special game mode,
It is of greatest concern whether the winning sphere received by the movable member follows any of the plurality of prize areas provided along the flow path.

That is, at the time of occurrence of the special game mode, the place where the line of sight of the player gathers is the lower part of the gaming machine arranged on the game board, especially near the special winning opening 29.

Therefore, here, by concentrating information such as the winning number, the number of rights, and the continuation confirmation, which are the game information at the time of the special game mode, the player can accurately grasp the progress status of the special game while changing the special game mode. It can be carried out with technical intervention, such as adjusting the resilience of the hitting ball launcher in a manner that is advantageous, ie, a cycle update.

(C) Auxiliary recessed chambers The auxiliary recessed chambers 24, 24 are provided on both left and right sides of the recessed chamber 20 so as to communicate with the recessed chamber so that the ball can freely flow between the recessed chamber 20 and serve as a mouth of the recessed chamber into which the ball can flow. The opening window 11A is present only in the main recessed chamber 20, and the portion of the mounting substrate 11 corresponding to the auxiliary recessed chamber 24 is a see-through window formed of a transparent member so that a player can see the inside thereof. Therefore, direct inflow of a hit ball from the game board side into the auxiliary concave chambers 24, 24 is prevented by the presence of the transparent member.

In this way, forming the front portion corresponding to the auxiliary concave room 24 in the see-through window portion 25 covered with the transparent member prevents the reduction of the game area due to the enlargement of the opening window 11A as the mouth of the concave room. Thus, it is possible to perform various works in which the concave chamber is substantially enlarged and a game is produced inside the concave chamber.

In the embodiment, a large movable body is arranged and shown to a player.

Reference numeral 13 in the drawing denotes a concave chamber case, which is formed by partially coloring or patterning a transparent member with a sticker or the like, and illuminating the main chamber with a lighting lamp 26 from behind.
The interior of the recessed chambers 20 and 24 is enhanced by making the interior of the recessed chambers 20 and 24 appear to be raised.

Background Model In FIGS. 1, 3 and 4, a background model 40 is disposed at the rear of the main recessed chamber 20.

The background model 40 simulates the shape of a robot, and has a head 41 having a flange 42 (second movable body) capable of opening a mouth, a torso 43 capable of moving up and down, and Two arms that can open and close both hands in synchronization with the movement (first
(Movable body) 44 and a leg 45 integral with the body 43.

Reference numerals 46 and 47 denote an inner frame and an outer frame which are assembled so as to be able to move up and down.The head 41 is fixed to the upper part of the inner frame 46, and the trunk 43 and the legs 45 are fixed to the outer frame 47. ing.

(A) Head The structure for opening and closing the flange 42 of the head 41 will be described with reference to FIGS. 6 and 7. FIG.

First, the rear end of the flange 42 is supported in the middle frame 46 so as to be rotatable about a shaft 48, and a wire 49 is fixed to an arm end extending backward from the shaft 48 by a screw.

The wire 49 passes through a guide 52 provided on a rear lid 51 constituting the middle frame 46, passes below the middle frame 46, and is connected to a pin 53. As shown in FIG. 2, this pin 53 is implanted at the tip of a lever 55 that is pulled up about a shaft 55A by an auxiliary solenoid 54 of an auxiliary drive device frame 50.

Therefore, the pin 53 is normally in the lower position (FIG. 7) due to the weight of the plunger of the auxiliary solenoid 54,
When the pin 54 is urged, the pin 53 moves to the upper position (FIG. 8), and the flange 42 goes down to open the mouth of the robot.

In FIG. 7, an LED 57 and a lamp 58 are arranged inside a head 41 by a printed circuit board 56.

LED57 is the part 57A of the helmet of the robot (Fig. 3)
The lamp 58 illuminates the eye 58A and the tongue 58B.

A printed circuit board 59A is fixed in the middle frame 46, and two lamps 59 are mounted on the printed circuit board 59A.

The lamp 59 illuminates the translucent chest portion 43A of the robot from the inside through the slit 46A of the middle frame 46.

(B) Trunk and Arm The trunk 43 of the background model 40 shown in FIG.
Is lifted up together with the outer frame 47 by the auxiliary solenoid 60 provided in the main concave chamber 20 and reciprocated vertically in the main concave chamber 20.

The arm 44 of the background model 40 reciprocates in the left-right direction of the main recessed chamber 20 via a crank mechanism in conjunction with the vertical movement of the body 43.

6, 8, and 9, the operation unit 61 extends rearward from the lower portion of the rear surface of the outer frame 47, and the operation unit 61 is formed by cutting the notch 20 </ b> A on the rear surface of the concave case 13. The operating portion 61 is fixed to the plunger of the auxiliary solenoid 60 by penetrating and extending rearward.

Therefore, the normal operation unit 61 is at the lower position (FIG. 8) due to the weight of the plunger of the auxiliary solenoid 60 and the return spring 60B. When the auxiliary solenoid 60 is energized, the plunger 60
A is sucked, and the outer frame 47 is pulled up with respect to the middle frame 46 as shown in FIG. As a result, the trunk 43 moves up and down.

The arm 44 is reciprocated right and left in conjunction with the vertical movement of the body 43.

For this reason, a vertical shoulder shaft 62 is formed in the arm portion 44, and the shoulder shaft 62 is housed in the notch 43A on the back surface of the body portion 43, and is pressed from the rear by the outer frame 47. The arm 44 is supported so as to be able to reciprocate right and left around the center.

Due to the joint structure of the arm 44, the arm 44 can maintain a stable strength and structure that can withstand the impact of a hit ball.

In order to move the arm 44, an operation claw 63 is provided on the arm 44 so as to protrude from the shoulder shaft 62 toward the inside of the outer frame 47.

When the operation claw 63 is pushed up together with the outer frame 47, the operation claw 63 is brought into contact with the middle frame 46 to move the operation claw 63 from the right position in FIG. 8 to the left position in FIG. Cam to let
64 are provided.

Accordingly, when the body 43, that is, the outer frame 47 is moved upward, the operation claw 63 moves along the cam 64 from the right position in FIG. 8 to the left position in FIG. 3 (B) from the first state of FIG. 3 (A).
To the second state.

What should be noted here is the movement position of the hand portion 44A of the arm portion 44 in particular.

That is, the hand portion 44A is a special winning area 2 which is a special winning area.
9 (FIG. 3 (A)), which is located above the special winning opening 29 and located above the normal winning opening 28 which is a general winning area after leaving the special winning opening 29. The special prize port 28 is converted to a second state (FIG. 3 (B)) in which the prize is difficult to enter the normal prize port 28 but the special prize port 29 is opened.

Accordingly, the arm portion 44 functions as a winning probability changing member for the special winning opening 29, and the winning probability for the special winning opening 29 becomes low at the moment when the hand portion 44A is in the first state, and is converted to the second state. Can be enhanced at the moment.

Conventionally, in a pachinko machine having this type of variable prize winning device, the probability of the right to win the first special prize port is kept low in order to balance the profits of the player and the game store.

In addition, the player must win a special winning opening arranged on the game board, and the game ball received by the movable member at that time must win the special winning opening.

In the conventional variable winning device without such a movable member 12, the probability of the continuous winning in the special winning opening 29 after the right is generated is inevitably fixed to the same low level. In games such as this example, in which a special game is repeated with the continuation of winning a prize again, even if the right is finally generated after a long game, since the chance element is very strong, It often ends in one cycle after the occurrence, and it lacks the interest of pachinko games, but if the structure is such that the movable body is alternately switched between the first state and the second state as described above Although the probability of the first right occurrence is kept low, the continuous winning probability after the right occurrence is greatly increased as compared with the conventional case.

In the illustrated example, the winning probability is changed depending on whether or not the hand portion 44A is on the special winning opening 29.
In the case where the bottom surface 21 is lowered toward the back and a normal winning opening 28 or a special winning opening 29 is provided at the downstream end, the normal winning opening 28 or the special winning opening 29 It is possible to change the winning probability by controlling the position of the hand portion 44A as the winning probability changing member for the normal winning area and the special winning area.

Next, an example of a pachinko machine to which the above-mentioned variable prize device 1 is applied will be described.

In FIG. 10, the above-mentioned variable prize winning device 1 is disposed substantially at the center of a game area 2A defined by a guide rail 3 of a game board.

In the game area 2A, there are further provided general winning devices 4, 5, guide nails, windmills 6, out holes 7, and the like.

Below the variable winning device 1, a total of three specific winning ports, that is, left and right first specific winning ports 8, 8 and a central second specific winning port 9 are juxtaposed.

As shown in FIG. 11, the first specific winning openings 8, 8
A first operation detector (first operation switch SW1) is provided at the second specific winning opening 9 with a second operation detector (second operation switch SW1).
2) belong to.

In FIG. 11, reference numeral 65 denotes a prize ball collecting gutter for the variable prize winning device 1. The prize ball collecting gutter 65 allows a prize ball from the normal prize port 28 of the variable prize winning device 1 and a special prize port.
The winning ball dropped from 29 through the special winning detector 66,
It is collected by the count detector 67, and the total is counted.

Control device The control operation of the pachinko machine of the above example will be described in the following.
Description will be made according to the circuit diagram shown in FIG.

Reference numeral 70 in the figure denotes a clock oscillation circuit 71 and a counter circuit 72.
And a reference time generation unit having:

The counter circuit 72 includes a multi-stage frequency divider for an oscillation clock and a logic circuit connected to the frequency divider, and receives nine types of time signals T0 to T0 necessary for operation in response to the oscillation clock.
Producing T8.

T0 is 0.8 seconds, T7 is 0.4 seconds, T8 is 0.2 seconds, T3 is a time signal with a repetition cycle of 0.1 seconds, T1 is 1.3 seconds later, T2 is 3.2 seconds later, T4 is 1.6 seconds later, T5 is 16.8 seconds later , T6 are time signals that rise after 29.6 seconds.

 Next, the operation will be described.

 Next, the operation will be described.

Control of Normal Game State Normally, the opening / closing wing 12 is in the first state in which the variable winning device 1 is closed with respect to the game ball. However, when a hit ball wins in the specific winning openings 8 and 9, the solenoid SOL is operated as follows, and in this example, the opening / closing wing 12 is in the non-operating state where the game ball as the first state does not win at all ( (Fig. 3 (A))
The state is converted into an operation state (FIG. 3 (B)) in which the hit ball as a state can be easily received.

(B) Winning the first special winning opening The first winning detecting switch SW after winning the special winning opening 8
When 1 is turned on, the flip-flop FF1 is set via the waveform shaping circuit 73, and its output terminal is at H level, and
Invert to level.

The output of the AND gate 78 which has been at the H level until that time 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.

As shown in FIG. 13 (a), an output pulse (T3) is generated at the output terminal Q3 of the counter circuit 72, and the lamps 57, 58 in the head 41 of the background model 40, Tenth
The lamps 63 and 69 indicated by hatched portions in the figure are turned on with a blinking cycle of 0.1 second. 0.8 seconds after the start of counting, an output pulse (T0) is generated at the output terminal Q0 of the counter circuit 72,
Through a two-input AND gate 81 and an OR gate 82 which are opened by the Q output of the flip-flop FF3, the signal is sent to the solenoid drive circuit 83 as a blade operation signal S0, and the solenoid SOL is energized.

The blade operation signal S0 is shortened to a width of 0.5 seconds for the following reason, and causes the opening / closing blade 12 to open / close once.

That is, after 1.3 seconds from the start of counting, the counter circuit 72
The output pulse (T1) shown in FIG. 13 (a) is generated at the output terminal Q1 of the flip-flop FF1 via the two-input AND gate 84 and the OR gate 85 which are opened by the output of the flip-flop FF2. And reset it to its initial state.

When the flip-flop FF1 is reset, the Q output of the flip-flop FF1 returns to the H level.
The output of 78 becomes 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 FF6 is set via the rising differentiating circuit 74 and the OR gate 75, and the output terminal thereof becomes L level. The state is released, and the timer 76 starts a time measuring 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 expires.

(B) Winning the second specific winning opening The second specific winning opening 9 is won and the second operation detection switch is
When SW2 operates, the opening / closing wing 12 performs the opening / closing operation only twice under the control described below.

First, when the second operation detection switch SW2 operates, the flip-flop FF2 is set through the waveform shaping circuit 86.

The flip-flop FF1 is also set by the Q output of the flip-flop FF2, and the reset state of the counter circuit 72 is released.

Therefore, the wing operation signal is generated 0.8 seconds after the start of counting, and the process of opening and closing the opening / closing wing 12 once is the same as in the case of winning the first specific winning opening.

However, in the case of a winning in the second specific winning opening, the output of the flip-flop FF2 becomes L level, so that two inputs A
ND gate 84 is closed.

Therefore, even if the output pulse (T1) shown in FIG. 13 (a) is generated at the output terminal Q1 of the counter circuit 72 at the time point when the above 1.3 seconds have elapsed, the two-input AND gate 84 does not accept this pulse. .

Accordingly, the counting of the counter circuit 72 proceeds, and the counting starts.
After a few seconds, an output pulse (T2) shown in FIG. 13 (b) is generated at the output terminal Q2 of the counter circuit 72.

This pulse is applied to the reset input terminal R of the flip-flops FF1 and FF2 through the OR gate 85, and resets both flip-flops FF1 and FF2. Both flip-flops
Since the Q outputs of FF1 and FF2 return to H level, the AND gate 78
Goes high, and the counter circuit 72 returns to the reset state.

Until this counter circuit 72 returns to the reset state,
As shown in FIG. 13 (b), the output terminal of the counter circuit 72
A second pulse is generated at Q0, and the two-input AND gate 78,
Through the solenoid drive circuit 83, the solenoid SOL is energized for 0.8 seconds.

 Therefore, the open / close wing 12 performs the open / close operation twice in total.

(C) LED flashing The number of rights display 19 LED1 to LED4, the winning number display 23
In a normal gaming state, the LEDs 1 to 5 are driven to blink by a pulse of 0.25 seconds by the operation of the AND gate 95 and the AND gate 120.

In other words, in a normal game state, it is used as a lighting device that enhances the decoration effect.

Conversion to special mode game state As described above, during the period in which the opening and closing wings 12 perform the opening and closing operations once or twice, the ball winning with the opening and closing wings as a guide is the concave chamber of the variable prize device 1. When a special prize port 29 as a continuation prize area for generating a special game state formed in 20 is won and detected by the special prize switch SW3, the operation is shifted to a continuous opening and closing operation up to 18 times. .

In order to convert to the special mode gaming state, in the circuit of FIG. 12, while the flip-flop FF6 maintains the set state, the gaming ball wins the special winning opening 29 and the special winning switch SW3 is turned on. To do, or more precisely, AND
It is necessary that the special prize switch SW3 be turned on while the gate 88 is opened by the Q output of the flip-flop FF1 provided through the OR gate 89 and the Q output of the flip-flop FF6 after the flip-flop FF1 is inverted. .

(A) Start of wait time When the special winning switch SW3 is turned on, a pulse is applied to the AND gate 88 via the waveform shaping circuit 87.

At this time, the AND gate 88 is opened by the Q output of the flip-flop FF1 or FF6.

Accordingly, the pulse passes through the AND gate 88 and is applied to the flip-flop FF3 to set it, so that the Q output of the flip-flop FF3 goes high and the output goes low.

At this time, the pulse is supplied to the flip-flop FF6 via the OR gate 77 and the counter circuit 7 via the OR gate 79.
2 and the flip-flop FF5 are temporarily initialized through the OR gate 91.

The flip-flop FF3 is set, and its output becomes L
By inverting the level, the reset state of the counter circuit 72, the flip-flops FF4 and FF5, and the right counter 92 is released.

The counter circuit 72 starts its counting function, and each of the flip-flops FF4 and FF5 enters a state in which a pulse is expected to be sent from the counter circuit 72.

That is, a “wait time” of 1.6 seconds, which will be described later, starts, and the sound effect generator 130 operates during the wait time,
A fanfare is generated from the speaker 131.

In addition, LED1 ~ LED4 of the number-of-rights display 19, winning number display
23 LEDs 1 to 5 are blinked and driven by a pulse of 0.25 seconds under the normal gaming state, but the flip-flop FF3
Is set and turned off at the same time as converting to the special prize mode,
The state returns to the state where the original functions as the number-of-rights display and the winning number display are exhibited.

(B) Operation of the background model The collar 42 of the head 41 opens and closes twice. That is, as shown in FIG. 14, the AND gate 101 includes an inverted signal of the time signal T4 from the Q4 terminal of the counter circuit 72 and a time terminal T7 from the Q7 terminal.
(0.4 seconds), two pulses are output during the wait time. This pulse is output from LE
It is sent to the center LED (continuation indicator light) 19A arranged together with D to turn on the continuation indicator light 19A twice, and the OR gate 1
The solenoid is added to the solenoid drive circuit 105 through 04, and the auxiliary solenoid 54 is energized twice. As a result, the wire 49 (the seventh
2) is the upper position twice, and the flange 42 of the head 41 is opened and closed twice.

At the same time, the output pulse from the AND gate 101 causes the four LEDs of the number-of-times display unit 19 to blink at the same time via the OR gates 96 and 94.

Further, the five LEDs of the winning number indicator 23 are simultaneously blinked via the OR gates 119 and 121.

This allows the player to know that the game has shifted to the special prize mode.

Although the output terminals Q0 to Q3 are initially at the L level, the D input is at the H level due to the operation of the inverter 93, so that each time a pulse is input, Q0 to Q3 go high in this order.

Therefore, after 1.6 seconds of the wait time ends,
The current number of exercises is displayed by the number of statically lit LEDs.

Since it is still the first time here, the number-of-rights display 19 is
Only LED1 remains lit. (C) Temporarily prohibiting the opening and closing operation As shown in Fig. 14, during the wait time, the opening and closing blades
12 opening and closing operations are temporarily prohibited.

This is because the AND gate 110 is inhibited by the Q output of the flip-flop FF5.

(D) End of wait time When 1.6 seconds have elapsed from the start of counting, a pulse (T4) is generated at the output terminal Q4 of the counter circuit 72, and the 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 switches to the H level and the output switches to the L level.

The Q output of flip-flop FF5 allows AND gate 110
Is opened.

The pulse generated at the output terminal Q0 of the counter circuit 72 is inverted via the inverter 111, and the inverted signal is
It is applied to the solenoid drive circuit 83 through 110.

Thereby, the continuous opening / closing operation of the opening / closing wing 12 is started for the first time.

In other words, as shown in FIG. 3 (A), the open / close wing 12 remains closed until 1.6 seconds have elapsed after the start of the counting.

When the output of the flip-flop FF5 falls to L level, the reset state of the winning number counter 115 is released via the OR gate 114.

Also, an AND gate is provided by the Q output of the flip-flop FF5.
90, AND gate 88 is also opened through OR gate 89.

The Q output of the flip-flop FF5 is the sound effect generator 1.
The melody is input to 30 and a predetermined melody is generated from the speaker 131 while the right is being generated.

Control of Special State Game State After the conversion to the special state game state, the opening / closing wing 12 performs the opening / closing operation up to 18 times. Here, the "maximum" of 18 times is a unit cycle of the special mode game and 1 cycle, and during this cycle, if a special winning opening 29 is further won, even if the opening / closing wing 12 This is because even though the 18 opening / closing operations have not been completed yet, the cycle is interrupted and the first new cycle is started.

For example, when the special prize switch SW3 is turned on again after the twelfth opening / closing operation is completed and the next cycle starts, the next thirteenth opening / closing operation is not the thirteenth of the previous cycle but the first of the update cycle.

The number of update cycles, that is, the number of times of exercising the right “q” of the special mode game is a maximum of 8 cycles (q = 8) in this example.
Is allowed up to.

Therefore, if the maximum number of opening / closing operations of 18 times per cycle is maintained, 18 × 8 opening / closing operations can be expected. Conversely, even in the first cycle, a prize in the special winning opening 29 is not obtained. If not, it is designed to end in that cycle. Also, in the control device of this example, a predetermined number of winnings (10
), The cycle ends.

(A) Operation before update In FIG. 14, when the 1.6-second way time elapses as described above, the signal generated at the output terminal Q0 of the counter circuit 72 is set to 0.
The inverted signal of the pulse every 8 seconds passes through the AND gate 110,
Applied to the solenoid drive circuit 83.

The solenoid SOL 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.

Operation of Background Model As described below, the torso 43 moves up and down, and the arm 44 swings left and right in conjunction with this, and the operation of hitting both hands is continuously performed.

That is, the counter circuit 72 added to the AND gate 106
Time signal T5 from Q5 rises after 1.6 seconds and AND gate 10
Open 6.

Therefore, a 0.4 second repetitive pulse T7 at the Q7 terminal of the counter circuit 72 is passed through the AND gate 106 and the OR gate 108.
Joins the solenoid drive circuit 109 and activates the auxiliary solenoid 60
Energize every 0.4 seconds.

As a result, the torso 43 moves up and down every 0.4 seconds, and the arm 44 swings right and left in conjunction with this, and the operation of hitting both hands is continuously performed.

More specifically, the hand portion 44A of the arm portion 44 is converted into the first state shown in FIG. 3A and the second state shown in FIG. The “first state”, which functions as a winning probability changing member, is a state in which the hand portion 44A is located above the special winning opening 29 which is a special winning area, making it difficult to win the special winning opening 29. The "second state" means that the hand portion 44A has left the specific winning opening 29 and is located above the normal winning opening 28 which is a general winning area, and it is difficult to win the normal winning opening 28 and the special winning opening 29 It is in a state of being opened.

The winning probability for the special winning opening 29 is that the hand part 44A is the first
It becomes low at the moment when it is in the state, and is raised at the moment it is converted to the second state.

In the conventional variable winning device without such a movable member, if the probability of the right to first win the special winning opening 29 is kept low, the special winning opening 29 in the number of right occurrences is inevitably provided. Although the probability of the continuous prize is fixed at a low level as well, the movable body is alternately switched between the first state and the second state as described above. The continuous winning probability after the right is generated will be much higher than before.

Winning Number Display During this opening / closing operation, many gaming balls win the variable winning device 1 through the opening / closing wings 12.

The total number of the winning balls is counted by the counter switch SW4, and it is checked whether it is within a predetermined number.

More specifically, the prize ball that has entered the variable prize device 1 is a prize ball from the normal prize port 28 or a special prize port 29.
Regardless of whether it is a winning ball from or not, it is collected by the count switch SW4 on the back of the game board, and the count switch is turned ON.

Each time the count switch SW4 is turned on, the waveform shaping circuit 113
, The pulse is input to the winning number counter 115.

The winning number counter 115 has its D input
, The output terminals Q0 to Q4 sequentially go high in this order up to the fifth winning ball.

Accordingly, the LEDs 1 to 5 of the winning number display lamp 23 are sequentially turned on, and the number is displayed based on the number of lights.

When the winning number reaches half of the predetermined number, here 5
Since the Q4 output of the winning counter 115 becomes H level,
The D input is switched to the L level via the inverter 116, whereby the display of the winning number from the sixth is switched to the blinking drive display. That is, the output Q of the winning counter 115 from the sixth
While 0 to Q4 sequentially fall to L level, L level output Q0
As a result, the AND gate 118 is opened through the inverter 117, so that the pulse (0.25 seconds) from the clock oscillation circuit 71 of the reference time generation unit 70 passes, and the winning number display lamps LED1 to LED5 are turned on through the OR gates 119 and 121. It is driven to blink sequentially.

Operation in the latter half of one cycle When the number of winnings reaches a half (5) of the predetermined number, the Q4 output of the winning number counter 115 becomes H level and is taken out as the first half end signal.

This first-half end signal is input to the flip-flop FF4 through the OR gate 100, and the flip-flop FF4 is set.

Also, when the open / close operation of the open / close wing 12 up to 18 times is performed up to 10 times, an output pulse (T5) is generated at the output terminal Q5 of the counter circuit 72, and the flip-flop is output through the OR gate 100. FF4 is set.

The Q output of the flip-flop FF4 allows the AND gate 102
And the AND gate 107 is opened.
Is forbidden.

Therefore, Q8 of the counter circuit 72 is passed through the AND gate 107.
The pulse T8 (0.2 seconds) is input from the terminal, and the OR gate 108
Through the solenoid driving circuit 109.

In other words, the auxiliary solenoid 60, which had been energized by a 0.4-second repetition pulse (T7), is energized by a half-repetition pulse of 0.2 second, and the trunk 43 of the background model 40 violently moves up and down. Accordingly, the arm 44 also vigorously opens and closes both hands to the left and right.

This is to instruct the player to hurry to win the special winning opening 29 even after half of one cycle has not been updated yet.

Therefore, upon receiving the set output of the flip-flop FF4, the sound effect generator 130 causes the speaker 131 to generate a melody with a tempo faster than the first half.

In the second half of this cycle, the AND gate 102,
Since the pulse (T7) from the Q7 terminal of the counter circuit 72 is input to the solenoid drive circuit 105 through the OR gate 104, the collar 42 of the head 41 also opens and closes together.

As described above, when the first half of one cycle (the winning number is 5 or the operation of the opening and closing wings is 10 times) has elapsed, by repeating the operation in which the arm 44 of the background model strikes the hand, The probability of falling into the space of the special winning opening 29 can be increased, and the chance of continuation can be increased.

(B) Updating the cycle Under the restriction of the number of winning balls of up to 10 in one cycle and before the opening and closing operations of the above 18 times are completed, fortunately, the special winning opening 29 again. When there is a winning ball in, it will be updated to a new cycle.

If the special winning switch SW3 performs the detecting operation again during this new cycle, this cycle is also updated to the next cycle with the same operation as above, otherwise the winning number counter 115 counts the number of pulses "10" At this point, the circuit returns to the initial state at the end of one cycle.

Fortunately, during the first cycle, when the special winning switch SW3 is turned on, the pulse generated in the AND gate 88 at this time causes the counter circuit 72, the flip-flop FF5 and the winning number counter 115 to temporarily return to the initial state, respectively. Returned and enter the wait time.

By resetting the flip-flop FF5, the temporary opening of the opening / closing operation of the opening / closing wing, the blinking of the lamp 19A, the opening / closing of the flange 41 of the background model 40, and the like are performed simultaneously with the transition to the special game state on the way.

During the wait time, the winning number counter 115 is reset by resetting the flip-flop FF5, and all the LEDs of the winning number display lamp 23 are turned off. Also, AND gate
The pulse generated at 88 is applied to the number-of-rights counter 92, incrementing the content of the counter, and in addition to its output terminal Q0, Q1 is additionally set to the H level.
The lighting state of only LED1 and LED2 is switched from lighting only. As a result, the first cycle is updated to the second cycle, and the content displayed on the number-of-rights display 19 indicates the number of times the right has been exercised.

The same applies to the case where the special winning opening 29 is again won in the transition to the second cycle, and the operation is similarly repeated.

At that time, each renewal point, that is, the end of each cycle, is clearly perceived by the player by the wait time in which the opening / closing wing 12 is closed for 1.6 seconds.

At the same time as the cycle update performed each time the special winning switch SW3 is detected, the right counter 92 immediately increments its content.

Fortunately, if it is updated up to the final cycle, the eighth, the special opening / closing operation of the total of 18 times as promised in the cycle or the generation of a total of 10 prize balls will occur. The game state is completed.

That is, when the special winning opening 29 is won in the middle of the seventh cycle, the output terminal Q3 of the number-of-rights counter 92 returns to the L level, and all of Q0 to Q3 become the L level, and the number-of-rights display
19 four LED1 ~ LED4 are all driven and displayed in blinking state,
Indicates that the last cycle is “8”.

At the same time, it was connected to the output terminal Q3 of the right counter 92.
The output of the NAND gate 99 falls to L level.

For this reason, in the eighth cycle (final cycle) currently in progress, the O of the special prize switch SW3 thereafter is set.
The N signal is no longer accepted by the AND gate 88.

When a total of 18 opening / closing operations promised in the eighth cycle have been performed, the counter circuit 72 sets the time when the total of 18 opening / closing operations are completed, more precisely, at the time when 29.6 seconds have elapsed after the start of counting, A pulse (T6) is generated at the output terminal Q6.

When a total of ten winning balls are generated, an end signal is generated in the NAND gate 122 as a decoder of the winning number counter 115.

The counter circuit 72, the flip-flops FF4 and FF5, the number-of-rights counter 92, and the winning counter 115 are reset when the Q output of the flip-flop FF3 returns to the H level through the OR gate 123.

The AND gates 95 and 120 are opened by the Q output of the flip-flop FF3. Therefore, the LEDs of the number-of-rights display 19 and the winning number display 23 indicate that the 0.2
With the pulse of 5 seconds, it returns to the normal state of blinking drive.

Since the output of flip-flop FF3 is at L level, AND
Gates 102 and 107 are prohibited.

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

Unfortunately, when one cycle in the middle is completed without being updated, ie, a total of 18 opening / closing operations with 1.6 seconds as one opening / closing operation unit are completed. In this case, a pulse is generated at the output terminal Q6 of the counter circuit 72 when 29.6 seconds have elapsed after the start of counting by the counter circuit 72, and as described above, all circuit systems are returned to the initial state, and special The mode gaming state is forcibly released and returns to the normal gaming state.

Therefore, after that, unless a series of operations from the winning of the first and second specific winning ports 8 and 9 are performed again, the special mode gaming state cannot be achieved.

The disadvantageous situation for this player is that during the above-mentioned cycle of 18 times as one unit,
It happens because there is no winning of 29.

On the other hand, during the opening / closing operation, when a large number of game balls win the variable winning device 1 through the opening / closing wings 12 and the total number of the winning balls reaches ten, the winning number counter 115
Becomes "10", an end signal is generated in the NAND gate 122, and the flip-flop FF3 is reset through the OR gate 123.

Therefore, the special mode gaming state is forcibly released.

(Effects of the Invention) According to the present invention, the movable member of the variable winning device is provided with a guide portion for guiding the game ball toward the concave chamber on the game ball guide surface of the movable member. Most of the game balls that flow in while being guided by the movable member are guided to the concave room by the guiding unit, so they fall without passing through the concave room and suddenly win the continuous winning opening as before. Without reaching the final scene of whether or not to play, the player will play the game ball in the concave room for a relatively long time, the game ball will follow any background, and will win a continuous winning opening or a general winning opening You can fully appreciate the real pleasure of playing.

Therefore, according to the present invention, it is possible to sufficiently increase the sense of expectation of winning a game ball to a continuous winning opening as compared with a conventional device, and to provide a variable winning device for a gaming machine which is extremely interesting.
