A display device 13 that is turned on or blinks at the same time as 12b is provided. Further, on the left side of the display device 13, there is provided a segment-type winning number display 14 for displaying the number of balls won when the variable winning device 30 is opened. Reference numeral 15 is a discharge display lamp that is lit when the prize ball is discharged, and 16 is a completion display lamp that is lit when the prize ball is stopped.

Furthermore, the auxiliary gaming device 5 is provided on the holding frame 20 of the pachinko gaming machine.
An operation switch 17 for giving a command to, and a display device 18 that is turned on when a special game mode occurs are provided.

Next, an example of the configuration of the auxiliary game device 5 will be described in detail with reference to FIGS. 2 to 4.

A fan-shaped cover part 52 is provided on the upper part of the component board 51 of the auxiliary game device 5, and an armor part 53 is provided below the cover part 52 at appropriate intervals. Then, a specific winning opening 54 is formed in the center of the upper surface of the armor portion 53, and a pair of guide pieces 55a, 55b project on both sides of the specific winning opening 54 so as to face the lower slope of the cover portion 52. A flow path toward the specific winning opening 54 is formed between the two.

In addition, in the armor portion 53, several game balls (5 in the embodiment)
A ball holding section 56 as a ball holding means having a space for entering is provided, and the game balls that have won the specific winning opening 54 flow down into the ball holding section 56 and are temporarily held and the ball holding section is also held.
The front surface of 56 is opened and closed by a transparent plate 57. That is, the number of spheres inside can be visually confirmed. Further, an opening portion 56a facing the end of the connection gutters 9a, 9b for guiding the game balls won in the above-mentioned jump-in type special winning openings 6a, 6b is formed in the inner portion of the ball holding portion 56.

On the bottom surface of the ball retaining portion 56, there is slidably arranged a movable plate 58 as a flow-down preventing member which is normally closed, and behind the ball retaining portion 56 is a driving means for the movable plate 58. A solenoid 59 is provided. When the solenoid 59 is excited, the plunger 59a contracts and the movable plate 58 moves rearward. When the solenoid 59 is demagnetized, the movable plate 58 is moved forward by the return spring 59b to close the bottom surface of the ball retaining portion 56. The solenoid 59 is provided with a mounting piece on the upper wall of the recess forming wall 60 formed integrally with the component substrate 51 below the ball retaining portion 56.
It is fixed at 61.

Two inclined plates 62, 63 are arranged in the recess forming wall 60, and the first inclined plate 62 on the upper side is gently inclined downward toward the rear. In addition, the upper surface of the first inclined plate 62 has a plurality of obstacle protrusions that randomly change the flow direction of the sphere.
62a is formed, and a space between the rear end of the first inclined plate 62 and the rear end of the recess forming wall 60 is equal to or more than one sphere.

As a result, the movable plate 58 is retracted, and the winning ball that has flowed down from the ball retaining portion 56 onto the first inclined plate 62 collides with the obstacle protrusion 62a and moves rearward while changing its direction at random and moves downward. Of the second inclined plate 63. In the center of the second inclined plate 63, a V winning opening (right occurrence winning opening) 64 that is a condition for generating a special game mode is provided. 65 is projected. The lower end of the rotary body 65 is coupled to a rotary shaft 66a of a motor 66 fixed to the bottom wall of the recess forming wall 60, and is always rotated by the motor 66 around a vertical shaft.

Therefore, the winning ball flowing down on the second inclined plate 63 is the rotating body 65.
As shown in Fig. 4, when it flows downwards, it can collide with its inner surface and flow into the V winning opening 64, but when the rotating body 65 faces sideways or forward. When it comes down, it collides with the outer peripheral surface of the rotating body 65 and cannot flow into the inside V winning opening 64, so it flows down forward as it is.

A prize winning frame 67 is attached to the lower part of the front end of the recess forming wall 60. A flow dividing portion 68 is provided at the center of the prize receiving frame 67, and general winning openings 69 are formed on both sides thereof. Second inclined plate 63
Game balls that flowed up and could not win the V prize hole 64 in the center wins in one of the general prize holes 69 on the left and right, and is the target of one-time prize ball discharge like a normal prize ball. Becomes

On the other hand, when the game ball flowing down on the second inclined plate 63 wins the V winning opening 64 in a timely manner, a special game mode (a right to open the variable winning device) is generated. In the special game mode, for example, the special winning opening 31 on both sides of the variable winning device described above
On condition that the prize a or 31b is won, the opening / closing door 33 of the variable winning device 30 is temporarily opened, and a lot of winning balls can be generated in a short time. Variable winning device 30 opened
Is controlled so as to be closed when a fixed time (for example, 10 seconds) elapses or when a fixed number of winnings (for example, 10) is reached.

In addition, a segment type display 70 is arranged in the center of the front surface of the winning prize frame 67, and by this display 70, the number of stored winning balls in the special winning openings 31a, 31b during the special game mode and the fluctuation thereof The number of times the winning device 30 has been opened can be displayed. Further, a display lamp 71 that blinks or lights up when a special game mode occurs is provided inside the cover portion 52, and a lens member 72 is mounted in front of it.

Further, in this embodiment, a prize detection device is provided in the specific winning opening 54.
21 is provided, and the game ball that has passed through the specific winning opening 54 can be immediately detected. Further, each of the dive-type specific winning openings 6a and 6b is also provided with a prize detector, and the signals from these detectors allow the control device to know how many balls are held in the ball holding unit 56. Is able to.

In the pachinko gaming machine (FIG. 1) of the above embodiment, when the operation switch 17 is turned on, the solenoid 59 in the auxiliary gaming device 5 is excited and the movable plate 58 is retracted. Therefore, the player has a specific winning opening 6a, 6
When a suitable number of game balls are accumulated in the ball holding section 56 by winning from b or 54, if the movable plate 58 is moved by operating the operation switch 17 as a hold releasing means, a plurality of balls can be moved at a time. Since the game ball flows down onto the lower inclined plate 62, the game ball can easily enter the V winning opening 64. Moreover, at that time, if the operation switch 17 is pushed at an appropriate timing while watching the movement of the rotating body 65, the game ball in the ball holding portion 56 can be flown toward the V winning opening 64. That is, the player can technically intervene in the game with his / her technique. As a result, it is possible to prevent the game from becoming monotonous and deteriorating in interest.

Further, in the pachinko gaming machine of this embodiment, when a fixed number (for example, 5) of winning balls are accumulated in the ball holding portion 56, the solenoid 59 is automatically excited by the control device to move downward on the inclined plate 62. It is designed to be made to flow down.

FIG. 6 shows an example of a control device that enables such control of the solenoid 59.

In the figure, the symbols S1 and S2 correspond to the specific winning a prize detectors disposed inside the jump-type specific winning a prize ports 6a and 6b, and S3 corresponds to the detector 21 inside the specific award winning hole 54. Further, S4 is an operation switch 17.

In this circuit, the detection signals from the specific winning prize detectors S1 to S3 are input to the counter CNT via the differentiating circuit DIF, and the number of winning balls to the specific winning port is counted. When a certain number is reached, a count-up signal is formed and supplied to the flip-flop FF via the OR gate G to set it. Then, the output Q drives the transistor Tr to excite the solenoid 59. At this time, the timer TM is started at the same time as the excitation of the solenoid 59 is started, and a time-up signal is output after a fixed time (1 second) to reset the flip-flop FF. Therefore, the movable plate 58 moved by the solenoid 59 opens the bottom surface of the sphere retaining section 56 for a fixed time. In the meantime, all the balls inside flow down.

On the other hand, when the operation switch S4 (17) is operated, the signal is supplied to the flip-flop FF via the OR gate G,
In order to set this, the solenoid 59 is excited regardless of the count value of the counter CNT, and the movable plate 58 is
Is released.

Further, when the timer TM resets the flip-flop FF and the excitation of the solenoid 59 ends, the output of the flip-flop FF clears the counter CNT. Therefore, even if the operation switch S4 (17) is operated before the maximum number of specific winning balls reaches 5,
The counter CNT starts counting from "0" again. Therefore, the content of the counter CNT always matches the number of balls in the ball holding unit 56.

FIG. 5 shows another configuration example of the auxiliary game device 5. In the figure, the same parts as those of the auxiliary game machine 5 of FIG.

The auxiliary game machine of this embodiment is one in which game elements are added to the embodiment of FIG.
A housing portion 81 formed so as to expand rearward is provided above the specific winning opening 24 having 21. A general winning opening 91 and a winning frame 92 thereof are provided above the housing portion 81.
Then, in the inner part of the side wall of the housing portion 81, the connection gutters 9a, 9b for guiding the game balls won in the jump-type specific winning openings 6a, 6b.
The terminal end 82 is open. Moreover, the bottom wall of the housing portion 81 is inclined forward (toward the front) and a plurality of flow path changing members 81a are provided in a protruding manner.

In addition, a pair of guide pieces 83 are provided on the front surface of the component board 51 so as to be positioned in the middle of the front end opening of the housing 81 in the height direction.
a and 83b are fixedly provided, and the guide pieces 83a and 83b are arranged so as to be spaced apart from each other by at least one sphere, and are gradually inclined toward the center. Winning frame
The game ball that has flowed down on the guide pieces 83a, 83b through the first flow path A between the 92 and the guide pieces 83a, 83b moves toward the center and continues downwards through the gap between the two. It is divided into one that flows down and one that enters the rear housing 81.

The game ball that has entered the housing 81 is directed toward the specific winning opening (54) while randomly changing the direction by the flow path changing member 81a, thereby improving the thrill of the game. That is, in this embodiment, the jump-type specific winning opening 6a, 6
Even if a game ball is won in b, it does not always flow into the ball holding section 56. However, in the upper part of the auxiliary game device 5, in addition to the first flow path A, the guide piece 83
Also from the second flow path B between the a, 83b and the armor portion 53, the specific winning opening 54
To the game ball can be won. Therefore, the winning rate to the specific winning port 54 as a whole game board is the first
It is almost the same as the example. However, since the number of game balls entering the housing 81 is several steps higher than the number of specific winning balls generated in the first embodiment, the flow path A,
It is possible to technically intervene by shooting a game ball aiming at B. Moreover, it enters the specific winning opening 54 by the way the game ball flows down in the housing part 81, and returns to the external main game part again. As a result, the thrill of the game is improved.

Further, in this embodiment, if two game balls are held in the ball holding section 56, or if the operation switch 17 is turned on, the movable plate 58 is automatically retracted, and the game ball inside the 1 It is designed to flow down onto the inclined plate 62. And
A through hole 62b is provided substantially in the center of the first inclined plate 62, and a V winning opening 64 is provided in the center of the prize receiving frame 67. The game ball flows down from the first inclined plate 62 to the second inclined plate 63. Is the V winning opening 64
Or you will win either one of the general winning openings 69 on both sides, but the game ball that has successfully flowed into the through hole 62b in the center on the first inclined plate 62 has a very high probability of winning in the V winning opening 64. It is a mechanism that can do.

In the above embodiments, the movable plate 58 has been described as being structured to slide in the front-rear direction, but it is rotated downward by 90 ° so that the game balls in the ball retaining portion 56 flow down. It can be structured.

Next, an example of a control circuit for controlling the entire game board including the auxiliary game device 5 as shown in FIG. 2 or 5 will be described with reference to FIG.

Note that the switch S5 in FIG.
In the figure, a V winning ball detector that detects a game ball that has won a V winning hole 64, switches S6 and S7 are special winning ball detectors that detect a ball that has won a special winning hole 31a or 31b, and switch S8 is a variable winning device. It is a prize detector in 30. Also,
LED1 and LED2 are indicators 70 for storing winnings and displaying the number of times of continuation, LED3 is a prize number indicator 14 on the upper part of the game board, lamp L ₁
Is a display lamp 71, a lamp provided in the auxiliary game device 5.
L ₂ , L ₃ , L ₄ , and L ₅ correspond to the display devices 13 and 18 on the upper part of the game board and the display devices 12a and 12b on both sides of the game board, respectively.

In this embodiment, when a game ball is won in the V winning opening 64 in the auxiliary gaming device 5, the V winning ball detector S5 detects it,
The flip-flop FF ₁ is set, its output Q is changed to the high level, and this state is held.

When the output Q of the flip-flop FF ₁ is set to the high level, the AND gate G ₁ is opened and the output of the oscillator OSC ₁ changes to the ramp L.
The indicator lamp 71 of the auxiliary game device 5 is blinked by being supplied to ₁ to notify that a special game mode (big hit) has occurred. Further, the sound effect generation circuit 73 is driven by the output Q of the flip-flop FF _{1, and} a sound effect such as a fanfare is generated from the speaker SPK.

On the other hand, a special game mode (big hit) in the auxiliary game device 5
Occurs, AND is generated by the output Q of the flip-flop FF _1.
Since the gate G ₂ is opened, when the game ball wins the special winning opening 31a or 31b during the occurrence of the specific game mode, the detectors S6, S7
Is detected, and the detected signal is waveform-shaped by the waveform shaping circuit 74 and is input to the winning memory counter CNT ₁ . In this way, the special winning hole during the special game mode
31a, with the number of winning ball to 31b are sequentially stored in the counter CNT _1, by the output of the counter CNT ₁ decoder DEC ₁ decodes, displays the special winning ball number segmented stored device LED ₁ Is displayed in.

The output of the prize memory counter CNT ₁ is supplied to the comparator COMP and compared with the output of the continuation number counter CNT ₂ , and the prize memory number M is larger than the continuation number S (M
> S), a high level signal is output. This is OR
It is supplied to the flip-flop FF ₂ through the gate G ₃ and the AND gate G ₄ .

Since the output of both counters CNT ₁ and CNT ₂ are all zero when the special game mode occurs, the first special prize hole
The counter CNT ₁ is first incremented by winning the prize in 31a, 31b. Then, in the comparator COMP, M
> S is determined, and the output becomes high level. This triggers the flip-flop FF ₂ and its output Q
Becomes high level and the timer TM is started, and the solenoid for driving the opening / closing door 33 of the variable winning device 30 SOL ₁
Is excited, the opening / closing door 33 is opened, and a game state in which a game ball can be easily won is entered. At the same time, the AND gate G ₈ is opened and the lamps L _{2 to} L ₅ are blinked by the output of the oscillator OSC ₂ .

Then, in this gaming state, when a predetermined time (for example, 10 seconds) has elapsed since the timer TM was started, a time-up signal is formed, the rising edge is detected by the differentiating circuit 75, and a one-shot pulse is formed. Is supplied to the flip-flop FF ₂ via the OR gate G ₆ ,
finish. That is, when the time-up signal is output from the timer TM, the flip-flop FF ₂ is reset, the solenoid SOL ₁ is demagnetized, and the opening / closing door 33 of the variable winning device 30 is rotated in the closing direction.

Further, when the open / close door 33 of the variable winning device 30 is open, the game ball won in the variable winning device 30 is detected by the prize detector S8, and the detection signal is waveform-shaped by the waveform shaping circuit 76 and the counter CNT. _It is fed to ₃ and counted. This count value is decoded by the decoder DEC ₃ and displayed on the segment-type winning number display LED ₃ (14). Further, the outputs Q ₁ and Q _{3 of} the counter CNT ₃ are supplied to the AND gate G ₇ to be ANDed, and the output thereof is supplied to the reset terminal of the flip-flop FF ₂ via the OR gate G _6. , When the count value of the counter CNT ₃ reaches “10”, the flip-flop
FF ₂ is reset.

Therefore, the flip-flop FF ₂ is reset and opened / closed after 10 seconds have passed after the opening / closing door 33 of the variable winning device 30 is opened, or the number of winnings to the variable winning device 30 reaches 10, whichever is earlier. Door 33 is closed.

On the other hand, when the flip-flop FF ₂ is triggered by the output of the comparator COMP and the output Q is changed to the high level, the continuation counter CNT ₂ is counted up through the differentiating circuit 77 and the decoder DEC ₂ displays the indicator LED. _The number of continuations is displayed in ₂ . Further, when the flip-flop FF ₂ is triggered and the output changes to the low level, the output of the AND gate G ₅ changes to the low level and the gate G ₄ is closed. As a result, the output of the comparator COMP becomes the flip-flop FF.
₂ will not be fed. Then, after that, the flip-flop FF ₂ is reset by the output of the timer TM or the counter CNT ₃ , and when the output is changed to the high level, the delay circuit 78 delays for about 1 second, and then
The AND gate G ₄ is opened, and the output of the comparator COMP can be supplied to the flip-flop FF ₂ again.

The value M of the prize memory counter CNT ₁ is greater than the value S of the continuation circuit counter CNT ₂ by only “1”. As the counter CNT ₂ is counted up, M = S. Therefore, the output of the comparator COMP is once changed to low level. Then, before the opening operation is finished again, there is a prize in the special prize hole 31a, 31b, and the prize memory counter CNT ₁ is counted up,
Even if the output of the comparator COMP is changed to the high level, the AND gate G ₄ is closed by the output of the flip-flop FF _2. Therefore, the flip-flop FF ₂ is not triggered, and it waits until the opening operation of the variable winning a prize device 30 is finished, the opening is finished and the flip-flop FF ₂ is reset, and the AND gate G _{4 is} opened one second later. After that, the output of the comparator COMP is supplied to the flip-flop FF ₂ , which triggers it to start the opening operation of the next time.

In this way, the opening operation of the variable winning device 30 proceeds, and when the eighth special winning ball is detected and the counter CNT ₁ becomes “8” before the opening operation is the eighth opening, the output
The flip-flop FF ₁ is reset by Q ₃ , the lamp L ₁ is turned off, and the special game mode is erased. Then, at this time, the flip-flop FF ₃ is triggered by the output of the flip-flop FF _{1, and} the output of the comparator COMP is taken in. Therefore, the eighth special winning ball enters before the opening operation reaches eight times, and the special game mode is performed. Even if disappears, the flip-flop FF ₂ is triggered by the high-level output Q of the flip-flop FF ₃ after the end of the open operation, and the open operation is executed only once.

As described above, in the gaming machine of this embodiment, if a winning ball to the V winning opening 64 occurs again in the auxiliary gaming device 5 before the number of times of opening the variable winning device 30 reaches eight, V
Flip-flop FF by the signal from the winning ball detector S5
₁ is triggered. At this time, since the output of the flip-flop FF ₁ is set to the high level by the previous trigger,
Output is the output Q of the flip-flop FF ₁ is changed to the low level by being input to the data terminal D of the flip-flop FF _1, special play mode disappears.

In other words, in this embodiment, even if a special game mode occurs,
The special game mode may disappear before the number of times of opening the variable winning device 30 reaches eight. However, if the special prize memory M is already larger than the number of continuation times S when the special game mode disappears,
The flip-flop FF ₃ takes in and holds the output of the comparator COMP, so that the opening / closing door 33 is opened only once even after M−S ≧ 2. When M = S, the special game mode disappears immediately after the ongoing opening operation ends.

The flip-flop FF ₃ is reset by being supplied with the signals from the differentiating circuits 77 and 79 through the gate G ₄ when the special game mode is generated or when the opening operation is started (from the second time onward), and the next special It is prepared to take in the comparator output to the flip-flop FF ₃ by winning memory.

[Effect] As described above, the present invention is provided with the special winning means for generating the special game mode, so that after the special game mode is generated, the variable winning device is converted into the second state advantageous to the player. The player can enjoy the increased profit and enjoy the satisfaction of the profit. On the other hand, the special winning mode is detected again by the special winning means during the special game mode so that the special game mode disappears, so that the player can play the game so that the special game mode does not disappear. Even during the special game mode, the player can enjoy the thrill of a thrilling game. Further, the auxiliary gaming device having the special winning means is provided with a ball holding means capable of temporarily holding the game ball, and a hold releasing means for generating a command signal for flowing down the game ball held in the ball holding means. As a result, the possibility of winning a game ball in the special winning means is increased by the action of the hold releasing means, and the expectation that a special game mode may occur is increased, and the interest of the game is increased even more. The effect is that you can.
