Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a continuous winning hole for updating a special game cycle, and is advantageous to a player in a first state which is disadvantageous to the player due to a ball introducing means such as a movable piece. The present invention relates to a central winning device of a pachinko machine that can be converted into a second state.

[0002]

2. Description of the Related Art In recent pachinko games, the contents of games have been adopted that include special games in which the profits received by the player are expanded more than in the normal game state. In such special games, the contents are expanded. One cycle in which the profit state is maintained is set under a certain condition, and the cycle can be updated when a predetermined condition is satisfied. Then, it is general to set a special game cycle update condition that a ball is won in the continuous winning opening in the central winning device while the special game cycle continues (before the cycle end condition is satisfied). . Therefore, in order to use the pachinko machine having such a game content, various types of central winning devices of the pachinko machine, which are provided with a continuous winning hole for updating the special game cycle, have been proposed by the applicant of the present application (for example, JP-A-58-112571 and JP-A-59-103685).

In the above-described conventional central winning apparatus, a continuous winning port is provided at the center of the lowermost part of the concave chamber forming the winning space, and the continuous winning is performed after flowing down the winning space through an appropriate route. By providing a relatively small model decorative member at a position (for example, the center of the back of the concave chamber) that does not significantly impede the flow down state of the ball , Care has been taken to enhance the decorative effect of the central winning device. In addition, in the central prize winning device, when a specific game state (such as a state where a ball is won in the continuation winning opening), by making the light emitting member provided in the central winning device itself emit light, There is also a system in which the fact that the game state has occurred is visually displayed.

[0004]

However, as in the conventional central winning device, merely providing a small model decorative member in the recessed chamber is not sufficient for decorative effect, and it is not a decoration that can enhance the enjoyment of the game. I couldn't say that it was working. In other words, in the central prize winning device that functions as the main game device in the special game and is the focus of attention of the player, it is expected to enhance the entertainment of the game with a certain amount of glitz, but in the concave chamber. It is very difficult to sufficiently enhance the decorative effect of the entire central winning apparatus by only providing a relatively small model decorative member.

In addition, a large number of various light emitting members for decoration are provided on the game board, front frame, etc. of the pachinko machine, and these are repeatedly lit and blinked at any time. There is also a point that it cannot be said that the player is effectively informed that a specific game state has occurred just by turning on the member. For example, a beginner who is unfamiliar with pachinko games cannot distinguish the operating state of the light emitting source for the purpose of decoration from the operating state of the light emitting source for the purpose of suggesting the occurrence (or disappearance) of a specific game state. In some cases, since the change in the gaming state cannot be clearly recognized, a great disadvantage may occur, or the original entertainment of the pachinko game may not be enjoyed.

Therefore, the present invention aims to further enhance the decorative effect for the player and the notification effect of the specific game state, and the basic technical idea thereof is the decorative effect of the central winning apparatus as a whole. The present invention focuses on the substrate as an arrangement configuration that enhances the position of the substrate, and provides a pair of dynamic decorative members on the left and right sides of the concave chamber of the substrate that have not been effectively used in the past.

[0007]

In order to solve the above-mentioned problems, a central winning device of a pachinko machine according to the present invention has a continuous winning opening (for example, a second winning opening 25) for updating a special game cycle. In a central winning device (6) of a pachinko machine, which has a ball introduction means (for example, a pair of movable pieces 15, 15) and can be converted into a first state that is disadvantageous to the player and a second state that is advantageous to the player , A recess chamber (19) with a depth width is formed from an opening (12) opened in a substrate (11) attached to a game board (1), and dynamic decoration is provided on both left and right sides of the recess chamber of the substrate. A member (for example, a pair of left and right dynamic decoration members 34, 34) is provided, and based on the game being in a predetermined specific game state, drive means (for example, a partition member drive mechanism including a motor 45, a cam 47, etc.). ) Drive Dynamic decorative member and so as to operate.

[0008]

By providing the dynamic decoration member separately from the recessed chamber in which the ball flows down, the dynamic decoration member does not affect the flow down of the ball. In the central winning device attached to the game board, the dynamic decorative members on the left and right sides of the recessed chamber enter the suitable visual range of the player during the game, and make the player clearly understand the operating state of the dynamic decorative member. be able to.

Further, as described above, the bottom surface 20 is formed with a concave chamber 19 in which the bottom surface 20 is slightly inclined downward toward the opening 12, and the support shaft 30 is provided on the front wall of the concave chamber 19.
A doll 31 is provided so as to be movable up and down by 30, and a shelf-shaped ball guide plate 32 is provided in front of the doll 31 so as to be slightly inclined downward toward the back of the recess chamber 19, and the sphere 31 is provided on both left and right sides of the recess chamber of the substrate 11. Semi-cylindrical dynamic decorative members 34, 34 are rotatably provided on the back sides of the formed pair of windows 33, 33, respectively. On the back side of the recessed chamber 19, the movable piece 15 described above is provided.
A movable piece drive mechanism for driving the first partition member 21 and the second partition member 21.
Partition member driving mechanism for driving the partition member 22, and the doll 31
A doll drive mechanism for driving the doll and a variable display member drive mechanism for driving the hanging curtain 35 as the variable display member hanging from above are provided in the concave chamber 19.

As shown in FIGS. 3 and 4, the movable piece drive mechanism is provided with two first solenoids 37, 37 as electric drive sources on a drive source attachment plate 36 provided on the back side of the recessed chamber 19. The rod 38 is connected to the plunger 38 of the first solenoid 37.
9 is fixed and one end of a spring 40 is connected to the connecting rod 39 for biasing, and a crank-shaped turning rod 41 is fixed to the other end of the support shaft 16 having a movable piece 15 attached to one end thereof. The pin 42 of the moving rod 41 is loosely fitted in the hole 43 of the connecting rod 39 described above. Therefore, in a state where each first solenoid 37 is demagnetized, each movable piece 15 is erected by the bias of the spring 40 to prevent the ball from entering the concave chamber 19, that is, it flows down in the game section 3. The first state is achieved in which the sphere is not introduced into the recess chamber 19. In this way, each movable piece 15
In the first state, the armor portion 13 extends downward from the left and right sides and the blocking wall 17 to function as a blocking member.

On the other hand, when each of the first solenoids 37 is excited, the plunger 38 is raised against the bias of the spring 40, and the rotary rod 41, the support shaft 16 and the movable piece 15 are moved to about 90 degrees.
Rotate once. In this way, when each movable piece 15 is rotated in the direction in which the upper end is tilted outward, the ball that has flowed down in the game section 3 is received on the movable piece 15 and guided to the ball guide plate 32, that is, the ball is received. Convert to easy second state. In the second state, the sphere received by each movable piece 15 rolls on the sphere guide plate 32 toward the back of the recess chamber 19, and then the inclined lower end of the sphere guide plate 32 and the front wall of the recess chamber 19 are separated. It falls on the bottom surface 20 of the concave chamber 19 through the gap between them, rolls toward the opening 12 due to the downward inclination of the bottom surface 20, and enters any of the first to third winning openings 24, 25, 26. . Thus, each movable piece 15 functions as a sphere introducing means for introducing the sphere into the concave chamber 19 in the second state. When each of the first solenoids 37 is demagnetized, the plunger 38 is lowered by the bias of the spring 40 to rotate the support shaft 16 back, so that the movable piece 15 rotates back and receives the ball easily. It returns from the 2 state to the 1st state in which the sphere is not upright.

The partition member driving mechanism shown in the drawings not only drives the first partition member 21 and the second partition member 22, but also drives the dynamic decoration members 34, 34 provided on the left and right sides of the recessed chamber of the substrate 11. The base plate 4 provided on the back side of the concave chamber 19
4, a motor with speed reducer 45 is attached as an electric drive source, a cam 47 is attached to an output shaft 46 of the motor 45, and drive pins 48 projectingly provided at the rear ends of the first partition member 21 and the second partition member 22, respectively. , 48 are loosely fitted in the substantially oval groove 49 of the cam 47 at a position where the phase is changed by about 180 degrees about the output shaft 46.

A first photo sensor 50 is provided as a stop position detector on the cam 47, and the first photo sensor 5 is provided by a projecting piece 51 projecting from the outer peripheral surface of the cam 47.
0 is activated. Therefore, the cam 47 always stops with the minor axis portion of the groove 49 oriented vertically and the major axis portion laterally oriented. In this state, since the drive pins 48 of the first partition member 21 and the second partition member 22 are fitted in the long diameter portions of the groove 49, the tip end portion of the first partition member 21 and the tip end of the second partition member 22. The part is closest to each other, so that the width of the second winning opening 25 is minimized and the first winning opening 2 is
4 and the third winning opening 26 have the maximum width. It should be noted that the second winning opening 25 is slightly wider than the diameter of the sphere even if it has the smallest width, and can sufficiently win the sphere.

The cam 47 is operated by the operation of the motor 45.
Is rotated, the drive pin 48 of the first partition member 21 and the second
The groove 49 into which the drive pin 48 of the partition member 22 fits is moved, and both drive pins 48 and 48 fit into the groove 49 while relatively moving to the short diameter portion of the groove 49. Therefore, both drive pins 4
The distance between the first and second partition members 2 and 8 is reduced.
The first and second partition members 22 rotate about the shafts 23, 23 in different directions, respectively, and the distance between the tip portion of the first partition member 21 and the tip portion of the second partition member 22 is gradually expanded.
When the cam 47 rotates about 90 degrees, the above-mentioned interval, that is, the width of the second winning opening 25 becomes maximum, and accordingly, the widths of the first winning opening 24 and the third winning opening 26 are reduced and become minimum. Becomes Then, when the cam 47 further rotates, the first partition member 2
The interval between the tip portion of No. 1 and the tip portion of the second partition member 22 is gradually reduced, that is, the width of the second winning opening 25 is gradually reduced, and accordingly, the first winning opening 24 and the third winning opening 26 are separated. The width gradually expands.

When the cam 47 is rotated approximately 180 degrees in this way, the width of the second winning opening 25 is minimized and the first winning opening 25 is
The maximum width of the winning openings 24 and the third winning openings 26 is almost 2
Rotating 70 degrees maximizes the width of the second winning opening 25 and minimizes the width of the first winning opening 24 and the third winning opening 26, and when rotating about 360 degrees, the first winning opening 24 and the second winning opening 26. The widths of the mouth 25 and the third winning opening 26 respectively return to the initial state. Therefore, when the cam 47 rotates, the second winning opening 25
The width of the first winning opening 24 and the third winning opening 26 gradually decrease and the ball that has flowed down on the bottom surface 20 of the concave chamber 19 is very easy to enter the second winning opening 25. That is, as the probability of winning increases, it is difficult to enter the first winning opening 24 and the third winning opening 26, that is, the probability of winning decreases. The probability of winning the second winning opening 25 is highest when the cam 47 rotates 90 degrees or 270 degrees,
At this time, the probability of winning the first winning opening 24 and the third winning opening 26 is the lowest.

In order to drive the pair of dynamic decoration members 34, 34, the partition member driving mechanism has support pins 52, 52 projectingly provided on the base plate 44 slightly above the cam 47,
The support pins 52, 52 are loosely fitted in the long holes 54, 54 of the horizontally long interlocking member 53 provided along the front surface of the base plate 44,
The receiving pin 56 is provided substantially at the center of the interlocking member 53 with which the claw piece 55 protruding from the outer peripheral surface of the cam 47 abuts, and one end of the spring 57 is connected to the base end hook portion of the receiving pin 56 to interlock. The member 53 is biased to one side, and the tips of the interlocking rods 58 protruding forward from the left and right end portions of the interlocking member 53 are loosely fitted into the holes of the arm portion 59 of the dynamic decoration member 34. Therefore, when the cam 47 rotates due to the operation of the motor 45, the claw piece 55 that rotates integrally with the cam 47 contacts the receiving pin 56, and the receiving pin 56 resists the bias of the spring 57. Press to the left. When the receiving pin 56 is pressed and the interlocking member 53 moves to the left side in FIG. 5, the interlocking rod 58 pivots the arm portion 59, whereby the dynamic decorative member 34 gently pivots around the shaft 60. . Then, when the cam 47 further rotates to move the interlocking member 53 sufficiently, the claw piece 55 moves the receiving pin 56.
As a result, the interlocking member 53 is returned to the right side in FIG. 5 by the bias of the spring 57, whereby the dynamic decoration member 34 is returned and rotated about the shaft 60.

As described above, the motor 4 of the partition member drive mechanism
When the cam 47 is rotated by the operation of 5, the first and second partition members 21 and 22 move to change the width of the second winning port 25, and the interlocking member 53 reciprocates left and right to perform both dynamics. The decorative members 34, 34 are reciprocally rotated.

As described above, according to the central winning device 6 of the present invention, the dynamic decorative members 34, especially on the left and right sides of the recessed chamber of the substrate 11 in the central winning device 6 which have not been effectively utilized in the past. 34, and these dynamic decorative members 3
Since the window portions 33, 33 for visually recognizing the visible portions 4, 34 are provided, the pair of dynamic decorative members 34, 34 do not affect the flow of the sphere in the recessed chamber 19, and therefore the dynamic decorative member 34. , 34 can be formed in an appropriate size (in the present embodiment, a semi-cylindrical shape that is long in the vertical direction). Moreover, the dynamic decoration members 34, 34 are within the suitable visual range of the player who is playing the game, and the player can clearly recognize the operating state of the dynamic decoration members 34, 34. Therefore, when these dynamic decorative members 34, 34 are activated,
The decorative effect is surprisingly expressed over the entire left and right sides of the central winning device 6, and the decorative effect for the player can be further enhanced.

The partition member driving mechanism is the second winning opening 2
As long as the first partition member 21 and the second partition member 22 that form part 5 can be moved to change the effective widths of the first to third winning openings 24, 25, 26, it is not limited to driving the cam 47. The configuration may be adopted, and for example, it may be driven by a solenoid via a link mechanism.

As shown in FIG. 4, the doll driving mechanism has a second solenoid 6 as an electric driving source on the back side of the base plate 44.
1 is provided, the swing rod 63 is swingably attached by the shaft 62 in the middle of the length while penetrating the base plate 44, and one end of the swing rod 63 is attached to the plunger of the second solenoid 61. The front end of the support shaft 30 protruding rearward from the doll 31 is engaged with the other end of the swing rod 63.
Therefore, when the second solenoid 61 is intermittently excited, the plunger reciprocates up and down to reciprocally swing the swing rod 63, and the swing of the swing rod 63 causes the doll 31 to move up and down. In this way, when the doll 31 is moved up and down by driving the second solenoid 61, when the game state is changed in the game, the doll 31 is moved up and down to visually display the fact to the player. Not only can it be done, but the decorative effect can be enhanced.

Further, in the embodiment shown in the drawings, the player can be informed of the change of the game state by hanging the hanging curtain 35 as the variable display member in the concave chamber 19. The variable display member drive mechanism for driving the hanging curtain 35 has a long lower plate 64 and an upper plate 65 shorter than the lower plate 64 on the upper surface of the concave chamber 19, and the lower plate separated from the upper plate 65. A guide member 67 having a guide groove 66 formed on 64 is provided in the front-rear direction, and a slide plate 68 is provided in the guide groove 66 so as to be movable in the front-rear direction.
One end of the curtain 35 is connected to the tip of the pinion gear 70, and the output shaft of the geared motor 69 provided as an electric drive source is connected to the pinion gear 70.
, And the pinion gear 70 is meshed with the rack gear 71 on the upper surface of the slide plate 68. Then, the second photosensor 72 and the third photosensor 73 for detecting the position of the slide plate 68 are provided at the rear end of the upper plate 65 and the rear end of the lower plate 64, and the second photosensor 72 acting on the second photosensor 72 is detected. The first blocking piece 74 is provided in the middle of the slide plate 68, and the second blocking piece 75 acting on the third photosensor 73 is attached to the slide plate 68.
Installed at the rear end of

The above-mentioned slide plate 68 is always located at the rear end portion in the guide groove 66, and is stopped with the second blocking piece 75 acting on the third photosensor 73. In this state, the hanging curtain 35 is pulled up by the slide plate 68 and stored in the front portion inside the guide groove 66.
Therefore, the player cannot see the curtain 35.
On the other hand, the operation of the geared motor 69 causes the pinion gear 7 to move.
When 0 rotates, the rack gear 71 that meshes with the pinion gear 70 moves forward with the slide plate 68, that is, the substrate 1
When the slide curtain 68 moves, the hanging curtain 35 hangs down into the concave room 19 from the slit hole of the ceiling surface of the concave room 19, and when the hanging curtain 35 hangs down sufficiently, the first blocking piece 74 moves. Acts on the second photo sensor 72. If the weight 76 is fixed to the tip of the hanging curtain 35, the hanging curtain 35 descends smoothly. Second photo sensor 72
Is activated, this causes the geared motor 69 to reverse. Therefore, the slide plate 68 retracts and the hanging curtain 35 is pulled up. When the slide plate 68 is fully retracted, the second blocking piece 75 acts on the third photo sensor 73, and the geared motor 69 is stopped. In this way, the curtain 35 is actuated by the geared motor 69 so that the recessed chamber 1
Since it appears and disappears inside 9, when the geared motor 69 is actuated when changing the game state, the hanging curtain 35 can hang in the recessed chamber 19 to inform the player of that fact, and the appearance and disappearance of the hanging curtain 35 can provide a decorative effect. Can be increased.

Next, a game in a pachinko machine provided with the central winning device 6 having the above-mentioned structure will be described.
In the normal state, both movable pieces 15 of the central winning device 6,
15 is the first state in which the ball is stopped upright and does not accept the ball, and the second winning hole 25 which functions as a special game right generation and continuous winning hole (so-called V hole) is in the narrowest state. is there.

In the above-mentioned state, the ball flowing down in the game section 3 enters the first specific winning opening 7 and the first specific winning detector 9 detects this ball and sends a signal to the control device 77.
Excites each of the first solenoids 37 of the central winning device 6 only once for a predetermined short time (for example, 0.5 seconds), and the ball is the second.
When entering the specific winning opening 8 and the second specific winning detector 10 detects this sphere and sends a signal to the control device 77, the control device 77 turns on each first solenoid 37 for a predetermined time (for example, 0.8 seconds).
Excite only two times. Therefore, when the ball enters the first specific winning opening 7, the movable piece 15 of the central winning device 6 is moved for 1 second for 0.5 seconds.
The movable piece 15 is rotated only twice to be converted to the second state, and when it enters the second specific winning port 8, the movable piece 15 is converted to the second state only twice for 0.8 seconds.

In this way, the movable piece 1 of the central winning apparatus 6
When the balls flowing down in the game unit 3 flow down on the movable pieces 15 and 15 when 5, 15 are converted from the first state to the second state, the balls roll on the ball guide plate 32 and then are recessed. Room 19
Rolls toward the opening 12 on the bottom surface 20 and enters any of the first to third winning openings 24, 25, 26. Sphere is first
When entering the winning opening 24 or the third winning opening 26, this ball flows out to the back side of the game board 1 and becomes a winning ball, but the gaming state does not change. On the other hand, when the ball that has flowed down on the bottom surface 20 of the recessed chamber 19 is lucky to enter the second winning opening 25, the continuous winning detector 27 detects the ball and the control device 77 is given the right to the special game. Send a signal. The ball that has acted on the continuous winning award detector 27 is discharged to the back side of the game board 1 and becomes a winning ball.

When the control device 77 receives a signal from the continuous winning detector 27, the second solenoid 61 is intermittently excited to move the doll 31 up and down and the geared motor 6
9 is actuated to hang the curtain 35 into the recessed chamber 19, thereby visually displaying to the player the start of the special game. The doll 31 keeps moving up and down during the special game,
The hanging curtain 35 is immediately lifted after hanging in the concave chamber 19.

The special game in this embodiment is that the movable pieces 15, 15 of the central winning device 6 are converted from the first state to the second state for a predetermined number of times and a predetermined number of times (for example, 0.8 seconds, 18 times). Is set as one cycle, and the cycle is updated on the condition that the ball enters the second winning opening 25 during this cycle, and the cycle can be updated up to eight times. Then, during the continuation of the cycle (movable piece 1
5 and 15 convert from the first state to the second state up to the 18th time, until the number of balls to be received by the central winning device 6 reaches 10, or whichever of the earliest conditions is satisfied) When the player does not enter the second winning opening 25, the special game ends with the cycle regardless of the number of remaining cycles.

Further, in a preset state in a certain cycle (in the present embodiment, when five balls enter the first and third winning openings 24, 26 or when 10 seconds have elapsed after the start of the cycle). Then, by moving the first partition member 21 and the second partition member 22, the width of the second winning opening 25 is expanded, and at the same time, the width of the first and third winning openings 24, 26 is reduced, so that the sphere becomes second. This makes it easier for the player to enter the winning opening 25 and makes it difficult for the ball to enter the first and third winning openings 24, 26. That is, when the preset special game state is reached, the ball enters the second winning opening 25 that functions as a continuous winning opening rather than the probability that the ball enters the first and third winning openings 24 and 26 that function as general winning openings. By increasing the probability, it is made easy to move to the next cycle, and it is set so as to facilitate the continuation of the special game advantageous to the player.

Thus, as described above, in the present embodiment, it is assumed that the dynamic decoration members 34, 34 are operated by the partition member driving mechanism for driving the first and second partition members 21, 22. Therefore, when a specific game state is reached, the motor 45 is operated to move the first partition member 21 and the second partition member 22, and at the same time, the dynamic decoration members 34 provided on the left and right sides of the substrate 11, The driving of 34 is started (starting the rotating operation), and the fact is visually displayed to the player.
Thus, in the central winning device 6 according to the present invention,
Since the specific game state is notified by the driving state of the highly visible decoration members 34, 34, it is possible for a player who is unfamiliar with the game to clearly recognize the change in the game state, and the game state is unclear. It is possible to prevent as much as possible a situation in which the player suffers a great disadvantage due to the recognition or cannot enjoy the interest in the game.

Moreover, if a predetermined game progress state in the special game is set as a specific game state, the player can clearly recognize the game progress state during the cycle in the special game, and accordingly, depending on the game progress state. It becomes easier for the player to create a game strategy. That is, if the end condition of one cycle is satisfied, the cycle update will not be performed, and if the cycle update condition is satisfied early, the player will not be able to obtain a sufficient game profit and the special game When the ball is accepted by the central winning system 6 and hits the general winning award close to 10 balls, the winning award is continued until the final cycle. The player's game profit will be high. Therefore, as in the above embodiment, the latter half of the cycle is reached (for example, the first and third winning openings 2
If 5 balls enter 4 or 26, or 10 seconds have passed since the cycle started, it is set as the predetermined game progress state in the special game, and the player is efficient based on that information. It is possible to promote the progress of the game.

Incidentally, during the cycle, the balls are lucky to enter the second winning opening 25, and when the requirement for the special game cycle update is satisfied, the continuous winning detector 27 for detecting the balls entering the second winning opening 25. A signal is sent to the control device 77, and the control device 77 which receives the signal operates the geared motor 69 to hang the curtain 35 into the recess chamber 19. In this way, it is possible to clearly and visually display to the player that the ball has entered the second winning opening 25 as the continuous winning opening and the right to continue has been generated, that is, the cycle is updated.

Next, the control device 7 for controlling the above-mentioned game
Example 7 will be described.

The control device 77, as shown in FIG.
The first specific winning a prize detector 9, 9 is connected to the input side of the flip-flop 78. Therefore, when the ball enters the first specific winning opening 7, the first flip-flop 78 is set by the signal from the first specific winning detector 9, and the Q output is converted from "L" to "H". The Q output of the first flip-flop 78 is sent to the other input side of the first AND gate 80 whose one input is the Q0 output of the first counter 79. The first counter 79 receives the signal from the oscillator 81 and outputs the outputs at the Q _{0 to} Q ₄ outputs at the time intervals as shown in FIG. 9. Therefore, the first AND gate 80, which receives the Q ₀ output of the first counter 79 as one input, opens 0.8 seconds after the reset of the first counter 79 is released and outputs “H”, The first solenoids 37, 37 are excited via the drive circuit 82. When the first solenoids 37, 37 are excited, the central winning device 6
It is easy to receive the ball by rotating both movable pieces 15, 15 of the second
Convert to state.

Then, 1.3 seconds after the reset of the first counter 79 is released, the Q ₂ output becomes “H”, and this “H” causes the inverted Q output of the second flip-flop 83 to go to one side. Second AND gate 84, which is the input of
It is sent to the reset side of the first flip-flop 78 via the OR gate 85 to reset the first flip-flop 78. When the first flip-flop 78 is reset, the Q output is converted from “H” to “L”, so that the first AND gate 80 is closed and the first solenoids 37, 37 are demagnetized. That is, when the ball enters the first specific winning opening 7, the central winning device 6 rotates the movable pieces 15, 15 only once for 0.5 seconds to easily accept the ball from the first state in which the ball cannot be received. Convert to 2 states.

When the ball enters the second specific winning opening 8, the second flip-flop 83 is set by the signal from the second specific winning detector 10, and the first flip-flop is output by the Q output of the second flip-flop 83. 78 is set. When the first flip-flop 78 is set, the first AND gate 80 is opened by the Q ₀ output of the first counter 79 and the first solenoids 37, 37 are excited, as described above. Then, as shown in FIG. 9, after 3.2 seconds, Q
_{Since 1} is converted to “H”, this “H” resets the first flip-flop 78 and the second flip-flop 83 via the first OR gate 85. Therefore, when the ball enters the second specific winning opening 8, the central winning device 6 converts the ball into the second state where it is easy to accept the ball only twice for 0.8 seconds. When the second flip-flop 83 is set, the inverted Q output is converted to “L” and this “L” output is sent to one input side of the second AND gate 84. Even if the Q ₂ output of the 1-counter 79 is converted to “H”, the second flip-flop 83 is not reset by this.

When the central winning device 6 is in a second state where it is easy to receive a ball, when the ball flowing down on the movable piece 15 is lucky to enter the second winning hole 25 and a special game right is generated, the continuous winning detector 27 is activated. The ball is detected and the third AND gate 86 is detected.
Send a signal to one input side of. Third AND gate 86
Uses the output of the second OR gate 88 that inverts and inputs the Q ₃ output of the second counter 87 as the other input, and in this state, Q ₃ is “L” and the second OR gate 88 outputs “H”. Since it has been sent out, when it receives a signal from the continuous winning award detector 27, it opens and outputs "H". This "H"
Sets the third flip-flop 89, and the Q output of the third flip-flop 89 intermittently excites the second solenoid 61 via the second drive circuit 90. Therefore, the doll 3 provided in the concave chamber 19 of the central winning device 6
1 starts moving up and down to visually display to the player that the special game has started.

When the third AND gate 86 is opened,
The “H” output sets the fourth flip-flop 91, and the Q output of the fourth flip-flop 91 causes the geared motor 69 to normally rotate through the motor normal rotation drive circuit 92. Therefore, the hanging curtain 35 hangs down in the recessed chamber 19 of the central payout device 6 and visually displays that the player has the right to the special game. Then, when the curtain 35 is sufficiently lowered, the first blocking piece 74 of the slide plate 68 is moved to the second photo sensor 72.
The signal from the second photosensor 72 sets the fifth flip-flop 93. Fifth
When the flip-flop 93 is set, the Q output is converted to "H", and this "H" output resets the fourth flip-flop 91 to stop the operation of the motor forward rotation drive circuit 92, and at the same time, reversely drive the motor. Activate circuit 94.

When the motor reverse rotation drive circuit 94 is operated, the geared motor 69 is reversely rotated and the hanging curtain 35 is pulled up. When the slide plate 68 that has lifted the hanging curtain 35 in this way returns to the initial standby position, the second blocking piece 75 of the slide plate 68 acts on the third photosensor 73, and a signal from the third photosensor 73 The 5 flip-flop 93 is reset. Therefore, the operation of the geared motor 69 is stopped. In this way, when the ball enters the second winning opening 25, the geared motor 69 is actuated to cause the curtain 35 to appear in the recessed chamber 19 only once, thereby visually displaying to the player that the game state has been changed. .

When the third AND gate 86 opens,
“H” is transferred to the first counter 79 via the third OR gate 95.
Is once reset. The first counter 79 outputs Q ₁ output “H” 3.2 seconds after the reset, and this “H” sets the sixth flip-flop 96. The Q output of the sixth flip-flop 96 is sent to the other input side of the fourth AND gate 97 which inverts the Q ₀ output of the first counter 79 to form one input. Therefore,
The fourth AND gate 97 opens every time the Q ₀ output of the first counter 79 becomes “L”, and outputs “H” to excite the first solenoids 37, 37. Therefore, the central winning device 6
Converts to the second state for 0.8 seconds each time the Q ₀ output of the first counter 79 becomes “L”.

Then, the Q ₄ output of the first counter 79 outputs “H”, and this “H” resets the third flip-flop 89 via the fourth OR gate 98, and the inverted Q of the third flip-flop 89. Output 5th OR gate 9
When the sixth flip-flop 96 is reset via 9 the other input side of the fourth AND gate 97 becomes "L", so that the first solenoids 37, 37 maintain the demagnetized state thereafter. That is, when the ball enters the second winning opening 25, the central winning device 6 is at 0 from the Q ₁ output of the first counter 79 sending “H” to the Q ₄ output sending “H”. .8
Repeat the movable pieces 15, 15 up to 18 times per second first
The state can be converted to the second state.

When the movable pieces 15, 15 of the central payout device 6 are repeatedly converted to the second state as described above, the game section 3
A ball flowing down flows down onto the movable pieces 15 and 15, and the concave chamber 1
Enter within 9. And, this ball is the first to third winning openings 2
Any one of 4, 25, and 26 is entered, and one is detected by the counting detector 28. When the counting detector 28 detects a sphere,
A signal is sent to the third counter 100. Third counter 100
Q _{0 to} Q ₃ each time the signal from the counting detector 28 is received.
The output is sequentially converted, and the lamp display circuit 10 is output by this output.
The lamps 102 ... Arranged in the concave chamber 19 of the central winning apparatus 6 are lit via 1 to visually display the number of winning balls to the player. When ten winning balls enter the first to third winning openings 24, 25, 26, Q ₁ output of the third counter 100 and Q ₃
Since the output becomes “H”, the fifth AND gate 103 having the Q ₁ output and the Q ₃ output as inputs is opened, and the output of the fifth AND gate 103 is passed through the fourth OR gate 98 to the third flip-flop 89. To reset. That is, when 10 balls are won in the first to third winning openings 24, 25 and 26 of the central winning device 6, the special game is finished.

Thus, in the special game, the movable piece 1
When 5 and 15 rotate 18 times or when 10 balls are won, the special game end condition is satisfied and the special game ends regardless of the number of remaining cycles. However, if the ball enters the second winning opening 25 before the special game ending condition is satisfied, the cycle is updated and the special game can be continued. Then, in the present invention, when the preset condition is satisfied, the respective tip portions of the first partition member 21 and the second partition member 22 move to expand the width of the second winning opening 25, and at the same time, the first winning opening. The width of 24 and the third winning opening 26 is reduced so that the ball easily enters the second winning opening 25 which functions as a continuous winning opening.

In the present embodiment, the condition is that the movable pieces 15 and 15 are opened and closed 10 times or that 5 balls are won in the central winning apparatus 6. Therefore, the Q ₃ output of the first counter 79 is connected to one input side of the sixth OR gate 104, and the output of the sixth AND gate 105 that receives the Q ₀ output and the Q ₂ output of the third counter 100 is input. Is connected to the other input side of the sixth OR gate 104, and the output side of the sixth OR gate 104 is connected to the set input side of the seventh flip-flop 106. Therefore, the movable pieces 15, 15
When is opened and closed 10 times, the Q ₃ output of the first counter 79 is converted to “H”, and this “H” output sets the seventh flip-flop 106 via the sixth OR gate 104.

When five balls are won in the central winning device 6, the Q ₀ output and the Q ₂ output of the third counter 100 are “H”.
Then, the sixth AND gate 105 is opened, and the “H” output of the sixth AND gate 105 sets the seventh flip-flop 106 via the sixth OR gate 104. In any case, when the seventh flip-flop 106 is set, the Q output is converted into “H”, and this “H” sets the eighth flip-flop 107, and the Q output of the eighth flip-flop 107 causes the The motor 45 is started via the drive circuit 108. When the motor 45 operates, the first partition member 21 and the second partition member 22 gently rotate, and the width of the second winning opening 25 gradually expands. Along with this, the first winning opening 24 and the third winning opening 25. The width of 26 is gradually reduced. Therefore, it is converted into a state in which the ball easily enters the second winning opening 25.

Then, when the cam 47 for rotating the first partition member 21 and the second partition member 22 rotates and the projecting piece 51 provided on the outer peripheral surface of the cam 47 acts on the first photo sensor 50, "H" is sent to the other input side of the seventh AND gate 109 which receives the inverted Q output of the 7 flip-flop 106 as one input. The inverted Q output of the seventh flip-flop 106 is converted from “L” to “H” when the ball enters the second winning opening 25 and the continuation condition is satisfied and the third AND gate 86 is opened (described later). To do. Therefore, the seventh AND gate 109 is opened when the ball enters the second winning opening 25 and the projecting piece 51 of the cam 47 acts on the first photo sensor 50, and resets the eighth flip-flop 107.
Therefore, the first partition member 21 and the second partition member 22 stop at a predetermined position when the cam 47 rotates n times (n is an integer).

When the width of the second winning hole 25 is expanded as described above, or when the ball enters the second winning hole 25 before the width of the second winning hole 25 is expanded, the continuous winning detector 27 is provided. Detects the sphere and sends a signal to one input side of the third AND gate 86. The other input side of the third AND gate 86 is the second
Since "H" from the OR gate 88 is input, it immediately opens when a signal from the continuous winning award detector 27 is input to one input side and outputs "H" output. Third AND gate 8
The “H” output from 6 resets the first counter 79 once via the third OR gate 95. Therefore, the central payout device 6 ends the first cycle at that time, and after the Q ₁ output of the first counter 79 is converted to “H” in the same manner as described above, the movable piece 15 is moved to the first position by converting the Q ₀ output. The opening / closing operation is restarted from the first time. Further, the "H" output from the third AND gate 86 is sent to the fourth flip-flop 91, so that the geared motor 69 is actuated to lower the curtain 35 once in the recessed chamber 19 and cycle it to the player. Visually indicate that the update was done.

As described above, when the movable piece 15 is opened and closed 18 times, and the balls enter the second winning opening 25 before 10 balls are won in the central winning device 6, the cycle of the cycle is successively repeated. Updates are made. Updating of this cycle, since "H" is sent to the second counter 87 each time the third AND gate 86 is opened, central game through the lamp display circuit 110 by Q ₀ to Q ₃ output of the second counter 87 The lamps 111 ... Of the armor portion 13 of the device 6 are lit or blinked, and are visually displayed to the player. In addition, the above-mentioned lamps 102 and 111
Can be any lighting or blinking as long as it can notify the player by emitting light.
You may use D etc.

When the cycles are updated one after another and the number of cycles changes to eight, Q _{0 to} Q of the second counter 87.
_{The 2} output becomes “L” and the Q ₃ output becomes “H”, which converts the output of the second OR gate 88 into “L”. Therefore, the other input side of the third AND gate 86 becomes “L”, and the third AND gate 86 then continues to the continuous winning detector 2
It remains closed even when it receives the "H" signal from 7. Therefore, the movable piece 15 is opened and closed 18 times to open the first counter 79.
Or Q ₄ output of becomes "H", or central game device 6
10 balls are won and the Q ₁ output and the Q ₃ output of the third counter 100 become “H”, and the fifth AND gate 103
Of the third flip-flop 8 via the fourth OR gate 98 when either of the above "H" is output.
9 is reset. Therefore, the special game ends at this point.

Although the first partitioning member 21 and the second partitioning member 22 which are long in the front-rear direction are configured to be swingable in the above-described embodiment, the first partitioning member 21 and the second partitioning member in the present invention are arranged. 22 expands the width of the second winning opening 25 formed by both partition members, and accordingly, the first winning opening 24 and the third winning opening 2
Any configuration may be used as long as the width of 6 can be reduced. Then, the condition for moving the first partition member 21 and the second partition member 22 to increase the width of the second winning opening 25 is not limited to the above, but can be appropriately set by setting the game content.

Further, in the above embodiment, the movable piece 15 which functions as a part of the blocking member or the ball introducing means is rotatably mounted on the shaft, and the movable piece 15 introduces the ball into the concave chamber 19. In addition, although it has been described as a so-called second-type winning device in which the ball enters the second winning opening 25 as a requirement for generating a right for a special game and a requirement for continuation, the present invention is not limited to this. For example, the left and right sides of the opening 12 are surrounded by fixed wall-shaped blocking members, and a ball is introduced into the concave chamber 19 by a ball introducing means such as a guide trough from another prize opening provided, and this ball is the second prize. When a player enters the mouth 25, the right to play a special game is generated, and a variable prize device such as an attacker is converted into a state in which the ball is easy to enter on condition that the ball enters the starting opening provided elsewhere. It may be configured as a device.
