Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pachinko game machine, and more particularly to a pachinko game machine with improved drive control of a variable winning ball device.

In general, pachinko gaming machines that use pachinko balls to play games are widely used and are popular among players as one of the convenient cash registers. As is well known, pachinko machines have multiple safe holes and winning ball devices (Yakumono, commonly known as tulips) on the game board.
is set up, and when a player hits a pachinko ball,
If a ball lands in the safe hole or the Yakumono with a certain probability, a certain number of prize balls will be released. Conventional pachinko machines, for the purpose of providing services to players, open a predetermined number of yakumonos when a ball lands in a specific safe hole or winning area, or open a certain yakumono for a short period of time. Ta.
For this reason, conventionally, even if prize balls are awarded depending on the gaming state, a predetermined number of Yakumono are only created for a short period of time based on winning balls in a specific winning area, so players can If you want to win a large amount of prize balls by playing until the machine stops, you need excellent gaming skills and the patience to play continuously for a long time. For this reason, many experienced pachinko players, known as pachinko players, were able to win a large number of prize balls on a single pachinko game machine until the game was stopped. However, there is a desire for a gaming hall to provide many players with the opportunity to win a large amount of prize balls.

Therefore, the applicant of this application first filed the patent application No. 54-145643.
No. 1 and Japanese Patent Application No. 145644/1989, a variable winning ball device such as a Yakumono is made to be in a state where it is easy to win a prize for a relatively long time based on a specific gaming state, and 1.
We proposed a pachinko game machine that allows you to win a large amount of prize balls each time. However, the previously proposed system simply puts the variable winning ball device in a state where it is easy to win for a relatively long time, so the variable winning ball device is made variable by adjusting the adjustment state of the nail installed near the variable winning ball device. There are some winning balls that produce more than a dozen winning balls during one opening period of the winning ball device, and others that have almost no winning balls.
The winning probability varied more than expected depending on the machine. For this reason, in the previous proposal, even if a specific game state is entered, the number of prize balls that can be won varies widely depending on the machine, and once a specific game state is entered, a relatively large number of prize balls can be obtained. In some cases, it was not possible to give the bonus to the player.

Therefore, an object of the present invention is to make a variable winning ball device into a state where it is easy to win a prize based on a specific gaming state, and to ensure that a certain number of wins are achieved when the variable winning ball device is brought into a state where it is easy to win once. To provide a pachinko game machine that can guarantee the number of balls, prevent variations among pachinko game machines, and provide uniform service to players.

To summarize, this invention is such that when the variable winning ball device is set in a state where it is easy to win based on a specific game state, the state is maintained until a certain number of winning balls are generated.

Hereinafter, specific embodiments of the present invention will be described with reference to the drawings.

Next, with reference to Figures 3 to 5, the variable winning balls and
The configuration of the variable display device 30 will be explained. The variable winning ball/variable display device 30 is constructed by integrally mounting the variable winning ball device 40 and the variable display device 50 on a mounting plate 31. More specifically, the mounting plate 31 has an opening 32 formed therein. The opening 32 is selected to be a rectangular hole so that it becomes a winning area when the opening/closing plate 41 of the variable winning ball device 40 is opened. Also,
The mounting plate 31 is provided with display windows 33a, 33b, and 33c for displaying identification information drawn on the rotating drum included in the rotating drum display mechanism 50A. Additionally, a frame member 3 is provided at the upper position of the mounting plate 31.
4 is installed. A segment display 50B is attached to the frame member 34, and an inverted V-shaped ball receiving plate 341 is formed on the upper part of the segment display 50B. The balls received by this ball receiving plate 341 are guided to the back side through a hole that becomes the winning area 3a. The frame member 35 has passage areas 342, 3 for passing the balls in a laterally extending portion.
43 is formed. Furthermore, a plurality of obstruction nails 35 are installed in the mounting plate 31 at the upper position of the opening 32. A guide member 36 is installed between the obstacle nail 36 and the opening 32. The guide member 36 forms guide plates along the vertical direction at a plurality of locations in the lateral direction, and functions to allow the balls to fall while being guided in the vertical direction.

The variable winning ball device 40 opens the opening/closing plate 41 to the front to receive balls in a first state that is advantageous to the player, and in a second state that is disadvantageous to the player.
As an example of this state, the opening/closing plate 41 is closed to make it impossible to receive balls. To explain more specifically, the variable winning ball device 4 is connected to the opening 32.
0 is set. The variable winning ball device 40 is a frame member 4
2 (i.e. the part related to the opening 32)
An opening/closing plate 41 is rotatably attached to the opening/closing plate 41. That is,
Triangular side walls 411, 4 are provided on both sides of the opening/closing plate 41.
12 is formed. The side walls 411 and 412 are the shaft 41

is formed. The back of the frame member 42 is a cover 423
covered with When the opening/closing plate 41 is opened, the opening 32 becomes a winning area 43 where balls can be won. The winning area 43 is laterally divided into a plurality of winning areas 43a to 43c as necessary. The winning area 43a has conditions such that the opening/closing plate 41 can be opened again by a winning ball during the opening of the opening/closing plate 41 in a specific game state to put the variable winning ball device 40 in a state where it is easy to win a prize, as necessary. determined. For that purpose, the ball that has won a prize in the winning area 43a is guided to the back side, and the detection switch 44 provided below
Detected at a. The winning balls in the winning areas 43a to 43c are guided downward via paths 421 and 422, respectively.

An alignment path 37 is provided below the paths 421 and 422. This alignment path 37 has a width that is slightly larger than the diameter of one ball, and a length that is approximately similar to the length of a predetermined number of balls lined up that was allowed during the opening period of the variable winning ball device 40. Selected by On the front surface of the alignment path 37, a thin hole slightly smaller than the diameter of one ball is formed along the alignment direction, so that the winning balls stored in the alignment path 37 can be seen through from the front of the game board 1. do. An outlet 371 is formed below the alignment path 37 . Also,
An exit (a hole through which balls can pass) 372 is formed on the back surface near the upper entrance of the alignment path 37. This outlet 372 is configured to release the ball when a certain number (for example, the 10th ball) enters the alignment path 37 when the number of balls that is one less than a certain number is stored in the alignment path 37. Lead to the back side. A path 373 is formed on the back side of the outlet 372. A detection switch 44b for detecting a certain number of winning balls is provided at the end of the path 373.

Note that on the front cover of the alignment path 37, numbers corresponding to the number of balls that are aligned sequentially from the bottom may be drawn. In order to be able to see through the balls stored in the alignment path 37, instead of the slots, small holes may be bored at intervals equal to the diameter of the balls. In yet another modification, the width of the slot formed on the front surface of the alignment path 37 may be selected to be approximately equal to or greater than the diameter of the ball, and a transparent cover may be formed in front of it.

A winning ball storage and release mechanism 38 is provided on the back side of the alignment path 37 in association with the winning ball storage and release mechanism 38. The winning ball storage and release mechanism 38 is constructed by fixing a sliding lever 383 to a plunger 382 of a solenoid 381 and slidably supporting the sliding lever 383 with a support portion 384. The tip of the sliding lever 383 is bent into an L shape and faces the lower outlet 371 of the alignment path 37 . When the solenoid 381 is energized, the sliding lever 383 is slid upward to open the outlet 371 and release the winning balls stored in the alignment path 37. When the solenoid 381 is deenergized, the sliding lever 383 is slid downward to close the outlet 371 and store the winning balls in the alignment path 37. This state is shown in FIG. 4B.

In connection with the opening/closing plate 41, an opening/closing drive mechanism 45 is provided.
is provided. The opening/closing drive mechanism 45 includes a T-shaped lever 453 on a plunger 452 of a solenoid 451.
It is constructed by connecting parts of. The lever 453 is rotatably supported at its center by a pin 454 fixed to the mounting plate 31. At one end of the lever 453,
One end of rod 455 is engaged. Rod 455
The other end is a pin 4 formed on the side wall of the opening/closing plate 41.
Connected with 13. The other end of the short side of the lever 453 is tension-biased by a spring 456. By this,
When the solenoid 451 is electrically deenergized, the lower end of the lever 453 is pulled by the spring 456, and the tip of the long side is pulled down, thereby closing the opening/closing plate 1. Conversely, when the solenoid 451 is energized, the lever 453 rotates clockwise and pulls up the rod 455 to open the opening/closing plate 41 to the front.

In addition, in the illustration, as an example of a variable winning ball device, there is a state in which balls are easily won as a state that is advantageous to the player, and a state that does not allow balls to win as a state that is disadvantageous to the player. However, it goes without saying that various other variable winning ball devices may be used. For example, as another example of a variable winning ball device, there is a so-called chulip, in which a pair of ball receiving pieces are opened on the left and right sides to make it easier for the player to win the ball, and the player can easily win the ball. As a disadvantageous condition for the player, the ball receiving piece may be closed to make it difficult for the player to win a prize. Further, as yet another example of the variable prize winning ball device, an opening/closing plate that can be opened to the front of the game board 1 is provided, and a ball entrance for receiving one ball is formed at the top of the opening/closing plate. The opening/closing plate may be in a closed state, and the opening/closing plate may be opened based on a certain game state.

Next, details of the variable display device 50 will be described. Variable display device 50 includes a rotating drum display mechanism 50A and a segment display 50B. The rotating drum display mechanism 50A is constructed as shown in FIG.
That is, the rotating drum group 51 includes multiple rows of rotating drums 51a, 51b, and 51c. Identification information such as a picture pattern, a symbol, or a number (for example, a picture pattern such as a bell, a star, a yacht, or a number or a symbol such as an alpha alphabet) is drawn on the outer periphery of the rotating drums 51a to 51c in each row. Ratchet gears 52a to 52c (only 52c is shown in the figure) having the number of teeth corresponding to the number of identification information drawn on the outer periphery are fixed to the respective side surfaces of the rotating drums 51a to 51c in each row. Rotating drum 51 in each row
Each of a to 51c is loosely fitted onto the drum shaft 53 and supported so as to be individually rotatable by its frictional force. The drum shaft 53 is pivotally supported on both sides of the box 54. A gear 551 included in the rotational force transmission mechanism 55 is provided at one end of the drum shaft 53.
is fixed. The gear 551 is meshed with a transmission gear 552. A motor 56 for driving the rotating drum is attached to the side surface of the box 54. The motor 56 is a geared motor,
The drive gear is coupled to gear 552. The rotational force of the motor 56 is transmitted to the drum shaft 53 via gears 552 and 551, and drives the rotating drum group 51 to rotate. Furthermore, solenoids 57a to 57c are fixed to the rear rear surface of the box 54 for individually controlling rotation or stopping of the rotating drums 51a to 51c in each row. Plungers 571 of these solenoids 57a to 57c
are connected to one end of each of the locking levers 58a to 58c by a pin. These locking levers 58a~
A substantially central portion of 58c is supported by a shaft 581.
Both sides of the shaft 581 are fixed to both sides of the box 54. A claw-like portion 582 is formed at the tip of each of the locking levers 58a to 58c. The claw-like portions 582 of each of the locking levers 58a-58c engage with the corresponding ratchet gears 52a-52c, respectively, to stop the rotating drums in each row and maintain the locked state.

The specific game state that allows the variable winning ball device 40 to be in the first state for a relatively long time is a combination of identification information such as a picture pattern in each row displayed on the rotary drum display mechanism 50A. It is determined by a combination of the alignment state and the display state of numerical information displayed on the segment display 50B.

Other examples of the specific gaming state include only the display state of the rotary drum display mechanism 50A, only the display state of the segment display 50B when a plurality of digits are provided, or a specific winning state provided on the game board 1. The case may be based on any case where there is a ball passing through the area.

FIG. 6 is a game control circuit diagram of an embodiment of the present invention. In the configuration, the game control circuit 60 includes a variable display possible condition detection circuit 61, a rotating drum drive control circuit 62, a display drive circuit 63, a specific game state detection circuit 64, a predetermined number of winning balls detection circuit 65, and a drive control circuit 70. . In addition, if necessary, the game control circuit 60 may
6. Includes a numerical information display drive circuit 67.

Here, the variable display enable condition detection circuit 61 detects a condition that allows the variable display device 50 to display a variable display. The rotating drum drive control circuit 62 drives and controls the rotating drum display mechanism 50A based on variable display enable conditions. The display drive circuit 63 drives the segment display 50B to display based on variable display enable conditions. The specific game state detection circuit 64 detects the display state of the rotating drum display mechanism 50A and the segment display 50B.
Based on the combination with the display state of , it is detected that a predetermined specific gaming state has been entered. Note that the specific gaming state detection circuit 65 preferably includes a function of detecting not only the specific gaming state but also other gaming states and a condition that allows the variable winning ball device 40 to be in the first state. The predetermined winning ball number detection circuit 65 is
It is detected that there is a predetermined number of balls that can be won in the variable winning ball device 40 in a specific game state. The predetermined value provision state detection circuit 66 detects a state in which a predetermined value is given in a specific game state (for example, a state in which a relatively large number of prize balls set as the number of stoppages is given).

FIG. 7 is a detailed circuit diagram of the drive control circuit 70 and the predetermined winning ball number detection circuit 65. The drive control circuit 70 includes timers 711 to 714, an OR gate 72, a driver 73, a flip-flop 74, an AND gate 75, a timer 76, a differential circuit 77, and a driver 78. including. Here, the driver 73 drives the variable winning ball device 40 to the first state by energizing the solenoid 451 during the output period of the OR gate 72. The flip-flop 74 is set by the determination signal j0 and reset by the output of the predetermined value provision state detection circuit 66. That is, the drive control circuit 70 of this embodiment repeats the variable winning ball device 40 during the period from the time when the determination signal j0 is received until it gives a predetermined value (that is, reaches the end) to select the first ball that is easy to win. It guarantees that a certain number of winning balls will be produced at that time.
The alignment path 3 serves as a predetermined winning ball number detection circuit 65.
7 shows a case where a detection switch 44b is used to detect that a predetermined number of winning balls (for example, 10 balls) have been won.

Next, with reference to FIGS. 1 to 7, specific operations when playing a game with the pachinko game machine 10 of this embodiment will be described. The player puts the ball borrowed from the ball lending machine into the ball waiting gutter 13, adjusts the strength of the ball by rotating the ball hitting handle 14, and then turns the ball hitting switch 14.
Press s. Electric power is supplied to the motor 241 in response to the depression of the ball hitting switch 14s. depending on,
A motor 241 is rotationally driven, and a ball hitting cam 242 intermittently rotates a ball hitting hammer 243 to sequentially hit one ball into the game board 1. When a player is playing a ball hitting game in this way, when a ball lands in either the safe holes 2a to 2c or the Yakumono 4a, 4b, the prize ball release mechanism is activated and a predetermined number of balls are released for each winning ball. Control the release of prize balls.
On the other hand, when the ball hits any of the winning areas 3a to 3c, the corresponding detection switch 22a to 22
b derives a high level and supplies it to the drive circuit 621 via the OR gate 611, and the timer 6
Give to 22. Furthermore, the output of OR gate 611 causes flip-flop 631 included in display drive circuit 63 to be set. Accordingly, the drive circuit 621
By energizing the solenoids 57a to 57c to disengage the claw-like portions 582 of the locking levers 58a to 58c from the corresponding latch gears 52a to 52c, and rotating the motor 56, The display states of the rotating drums are varied by rotating the rotating drums 51a to 51c in each row. At the same time, the set output of flip-flop 631 is provided as one input of AND gate 632. The output clock pulse of the clock oscillator 633 is always applied to the AND gate 632 as the other input. For this reason, and gate 63
2 derives a clock pulse according to the set output of the flip-flop 631, and outputs the clock pulse to the ring counter 63.
Give to 4. The ring counter 634 responds to the clock pulse input to the segment display 50B.
The decoder driver 635 cyclically counts the numerical values 0 to 9 that can be displayed in the decoder driver 635.
and is applied to a determination circuit 645 included in the specific game state detection circuit 64. Decoder driver 635
decodes the count value of the ring counter 634 and displays the segment display 50 based on the count value.
The numbers displayed at B are sequentially changed in synchronization with the period of the clock pulse. In this manner, the rotary drums 51a to 51c are rotationally driven and the segment display 50B is variably displayed, whereby mechanically variable display and electrically variable display are performed simultaneously.

As described above, the rotating drums 51a to 51c
In a state where the segment display 50B is variably displayed, the player presses the stop command switch 17 so that the combination of display states of the rotating drums 51a to 51c in each row becomes a specific game state. Note that timer 6 starts after variable display starts.
If the stop command switch 17 is not pressed within a certain period of time set by the timer 622, a stop command is issued by the output of the timer 622. In response, the drive circuit 621 deenergizes the solenoids 57a-57c in a predetermined order (or in an irregular order) to sequentially stop the rotating drums 51a-51c. and,
The drive circuit 621 stops the rotation of the motor 56 after a short delay and also derives a high level signal indicating that all rotating drums have stopped. This high level signal resets the flip-flop 631 and is applied to the display state determination circuit 643 as a determination command signal. In response, AND gate 632 stops deriving clock pulses. Therefore, the count value of the ring counter 634 is not incremented, and therefore the count value of the ring counter 634 is not incremented.
Numbers corresponding to the count value counted at 34 are continuously displayed on the segment display 50B.

The display state determination circuit 643 determines the combination of identification information displayed on the rotating drums in each row based on the outputs provided from the sensors 641 and 642 in response to the determination command signal. By the way, as the sensors 641 and 642, for example, a photoelectric sensor having a light projecting section and a light receiving section is used. Each sensor 6
The light projecting portions and light receiving portions 41 and 642 are provided facing each other on both axially outer sides of all the rows of rotating drums. Although not shown in FIG. 5, on each side surface of the rotating drums 51a to 51c, first circles with different radii and angles corresponding to the identification information displayed on each rotating drum are formed. A portion with a through hole and a portion without a through hole are provided at positions on the circumference and the second circumference. This makes it possible to identify four types of identification information based on the combination of portions with and without holes. For example, if the part with a hole is set to logic ``1'' and the part without a hole is set to logic ``0'', four types of 2-bit codes ``00'' and ``01'' are generated. ，
By "10" and "11", it is possible to detect the combination of identification information of the rotating drums in each row. The display state determination circuit 643 then determines whether the rotating drum 51
A score is determined based on the combination of identification information displayed in a to 51c, and determination signals j1 to j4 corresponding to the score are sent to the drive control circuit 70 and the determination circuit 6.
Give to 45.

If the combination of identification information displayed on the rotating drums 51a to 51c is a combination of a specific game state,
That is, unless the combination is determined to give the maximum value (for example, all symbols are A), the display state determination circuit 643 determines that a value smaller than the maximum value should be given based on the combination at that time. One of the representing determination signals j2 to j4 is derived. Each judgment signal j2 to j4 corresponds to the corresponding timer 7.
12-714. Each timer 712, 7
13 and 714 are respective corresponding determination signals j
2, j3, and j4, high-level signals are derived for predetermined fixed times t2, t3, and t4. Here, timers 712 to 714
The fixed time set in is selected so that t2≧t3≧4, for example, t2=10 seconds, t3=6
seconds, t4=4 seconds. Note that the determination circuit 64
5, the judgment signal is other than j1 (i.e. j2 to j
4), the display state of the segment display 50B is not determined at all.

For example, assuming that the display state determination circuit 643 derives the determination signal j2, the timer 712 derives a high level signal for a certain period of time t2. This high level signal is applied to the driver 73 via the OR gate 72. In response, the driver 73 continuously energizes the solenoid 451 for a certain period of time t2. Therefore, the variable winning ball device 4
0 opening/closing plate 41 is opened for a certain period of time t2,
Driving balls are allowed to win. At this time, when a ball enters the winning area 43a to 43c, the prize ball releasing mechanism releases a predetermined number of prize balls according to the winning ball.

Next, a case will be described in which the combination of identification information displayed on the rotating drums 51a to 51c in each row is determined to give the maximum value. In this case, the display state determination circuit 643 uses the determination signal j1
is derived and provided to the determination circuit 645. Judgment circuit 6
45 is a ring counter 6 according to the determination signal j1.
It is determined whether the count value of 34 is in a display state (for example, a state in which 7 is displayed) in which the maximum value set by the combination setting section 644 should be given.
At this time, the determination circuit 645 determines whether the rotating drum 51a
Even if the combination of display states of ~51c is the state that gives the maximum value, if the segment display 50B does not display 7, the maximum value giving command signal j
0 (high level) is not derived. In this case, the timer 11 operates for a certain period of time t1 in response to the determination signal j1.
, and a high level signal is derived during that period. Here, the fixed time t1 is the timer 7
longer than the fixed time t2 set in 12,
In addition, even if the number of balls that can be hit per unit time (i.e., the batting speed) is taken into account, there is a period of time (for example, 20 seconds). The output of timer 711 is given to driver 73 via OR gate 72. In response, the driver 73 energizes the solenoid 451 to close the opening/closing plate 41.
to be established. Then, the timer 71 is activated for a certain period of time t1.
When the time is measured, the output is set to a low level, and the opening/closing plate 41 is closed.

Further, in accordance with the output of the OR gate 72, a differentiating circuit 77 derives a differentiated pulse and supplies it to the driver 78. In response, driver 78 energizes solenoid 381 for a period of time to
71 is opened to release the stored balls. These stored balls are used to release the prize balls.

Next, when a specific game state is reached, which is a feature of this invention, that is, the combination of display states of the rotating drums 51a to 51c becomes a predetermined state that can give the maximum value (all display states with the symbol A), and When the display state of the segment display 50B reaches a state where 7 is displayed, the following operation is performed. That is, the determination circuit 645 derives a high level signal indicating that a specific gaming state has been established and supplies it to the AND gate 646. At this time, the AND gate 646 detects the predetermined value provision state detection circuit 66
Since the low level of the output of is inverted to the high level, a high level judgment signal j0 is derived. This judgment signal j0 causes flip-flop 74 to be set. Therefore, when a specific gaming state is entered, the set output (high level signal) of the flip-flop 74 is given as one input of the AND gate 75. The other input of the AND gate 75 is provided with the output of the timer 76 (in this case, a low level signal) inverted to a high level. Therefore, the AND gate 75 continuously derives a high level signal during the set output period of the flip-flop 74 and supplies it to the driver 73 via the OR gate 72. The driver 73 opens the opening/closing plate 41 by continuously energizing the solenoid 451 during the period when the high level signal is applied from the OR gate 72 in the same manner as described above. In this state, the balls hit into the winning areas 43a to 43c with a relatively high probability, and the balls hit the alignment path 3.
It is stored within 7. Then, when there is a certain number of winning balls allowed during one opening period of the variable winning ball device 40 after a specific gaming state, the winning balls go to the back side via the exit 372 at the upper part of the alignment path 37. The detection switch 4 is guided through the path 373.
This will lead you to 4b. Accordingly, the detection switch 44b detects a certain number of winning balls and sets its output to a high level. In response, the timer 76 sets its output to high level for a certain period of time, and the AND gate 75
make it immobile. Therefore, the driver 73 temporarily closes the opening/closing plate 41. At this time, the differentiating circuit 77 differentiates the output of the OR gate 72 and provides a differentiated pulse to the driver 78. In response, driver 78 energizes solenoid 381 for a shorter time than the fixed time set by timer 76 . In response, solenoid 381 attracts plunger 382 to pull up slide lever 383 and open outlet 372. For this reason, the winning balls that had been stored in the alignment path 37 until then are released to the path 213, and 1
It is used for discharging a predetermined number of prize balls for each winning prize ball.

After the detection switch 44b derives the detection output, when the timer 76 measures a certain period of time, the output is set to a low level and the AND gate 75 is activated. In response, the AND gate 75 again derives a high level signal and drives the opening/closing plate 41 to open in the same manner as described above. In this way, once the specific game state is entered, the state where the variable winning ball device 40 is easy to win continues until a certain number of winning balls are generated, and once a certain number of winning balls have been generated, the variable winning ball device 40 continues to be in a state where it is easy to win. After the winning ball device 40 is driven to a state in which it is difficult to win, it is again controlled to be in a state in which it is easy to win. With this, the player can reliably generate a certain number of winning balls in a state where the variable winning ball device 40 is easy to win once,
It has the advantage that a certain number of winning balls can be reliably won regardless of variations in the winning probability from machine to machine due to nail adjustments, etc.

After the specific game state, each time the variable winning ball device 40 opens the opening/closing plate 41 and enters a state where it is easy to win, a certain number of winning balls are guaranteed.
The number of stops is reached much faster than in normal pachinko games. In this case, the predetermined value provision state detection circuit 66 detects that the number of stops has been reached, and the flip-flop 74 is reset with this output. Therefore, the AND gate 75 does not derive a high level from now on, and the repeated opening drive operation of the variable winning ball device 40 ends.

In addition, in the above-mentioned embodiment, the number of winning balls that can be stored in the alignment path 37 is set to be a relatively small number (10 pieces), and the variable winning ball device 40 is set in a state where it is easy to win a winning ball until a certain number of winning balls is generated. , the case where the state is changed to a state in which it is difficult to win after that has been explained, but the number of winning balls that can be stored in the alignment path 37 is selected to be a relatively large number (for example, 50), and the detection switch 44b detects a certain number of balls. The flip-flop 74 may be reset based on the Furthermore, in the above-mentioned embodiment, after the judgment signal j0 is received, the variable winning ball device 40 is activated every time there is a certain number of winning balls until the predetermined value imparting state detection circuit 66 detects that the number of winning balls has been reached. Although the case where the opening/closing drive is repeated has been described, other conditions may be selected as the repeating opening/closing driving conditions. for example,
A detection switch 44a for detecting a winning ball in the winning area 43a may be provided, and the flip-flop 74 may be reset by the output of the detection switch 44a.

By the way, in the above-mentioned embodiment, a detection switch 44b is provided as a predetermined number of winning balls detecting means for detecting that a certain number of winning balls have arrived in the alignment path 37, and a detection switch 44b is provided as a means for detecting the number of winning balls in order to display the number of winning balls in the winning area 43. Although the case where the winning ball itself is shown has been described, various other embodiments are possible.

FIG. 8 is a circuit diagram showing another embodiment of the predetermined winning ball number detection circuit. In this embodiment, a detection switch 651 for detecting a winning ball in the winning area 43 is provided in place of the detection switch 44b. The output of the detection switch 651 is given as one input of an AND gate 652. The other input of AND gate 652 receives the set output of flip-flop 74. The output of AND gate 652 is given to counter 653 as an addition command signal. This counter 653 counts the number of winning balls that have entered the winning area 43 when the variable winning ball device 40 is in a state where it is easy to win after a specific game state. The count value of the counter 653 is given to the comparison circuit 654, and
The signal is supplied to the numerical information display drive circuit 67 and displayed on the numerical information display 6. The comparison circuit 654 compares the constant number set in the setting section 655 with the counter 653.
When the counted value reaches a certain number, an operation command signal is given to the timer 656. The timer 656 derives a high level signal for a certain period of time in response to the coincidence output of the comparator circuit 654, and outputs a high level signal for a certain period of time,
5 is disabled and the counter 653 is reset. The configuration of the drive control circuit 70 is the same as that in FIG. 7, so the same parts are indicated by the same reference numerals and detailed explanation thereof will be omitted.

Incidentally, the embodiments shown in FIGS. 6 and 7 described above show a case in which a hardware circuit is used to achieve the operation of the present invention, but the technical idea of the present invention is that a program is implemented using a microprocessor. This can also be done by treatment. In that case,
Those skilled in the art will easily be able to set a program to perform the operations of the circuits shown in FIGS. 6 and 7, so a detailed explanation thereof will be omitted.

The variable winning ball device can be driven to a state where it is easy to win a prize until a certain number of winning balls is generated, and it is possible to prevent variations in the number of winning balls from machine to machine or from player to player when the variable winning ball device is in a state where it is easy to win a prize. A unique effect is produced. In addition, since it is possible to prevent variations in the number of winning balls when the variable winning ball device is in a state where winning is easy, it is possible to equalize the service to many players without giving a large amount of prize balls only to a specific player. There is also.

Furthermore, when the variable winning ball device is in a state where it is easy to win a prize after a specific gaming state, if a repeat condition is satisfied until a certain number of winning balls is generated, the variable winning ball device is repeatedly set in a state where it is easy to win a prize. Therefore, the variable winning ball device can be put in a state where it is easy to win many times, and the player can play the game in a state where it is easy to win for a relatively long time, and there is also the effect that the player can enjoy the exciting feeling for a long time.
