Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a pachinko game machine, and in detail,
This invention relates to a pachinko game machine equipped with a variable winning ball device that can freely change between a first state that is advantageous to the player and a second state that is disadvantageous to the player.

[Prior Art] In this type of pachinko game machine, the variable winning ball device, which is generally known from the past, is configured such that, for example, when a ball hits a predetermined first winning area, the variable winning ball device is controlled to a first state in a manner that can give a relatively small gaming value, and a ball that enters the variable winning ball device controlled in the first state enters a specific winning area and is preliminarily When a predetermined gaming state is reached, a specific gaming state is generated and the variable prize winning ball device is controlled to be in the first state for a second predetermined period during which a relatively large gaming value can be given, thereby providing great satisfaction to the player. There was something that made me feel. In this type of pachinko gaming machine, the second predetermined period of time associated with the occurrence of the specific gaming state is set so that the player can repeatedly experience the excitement associated with the occurrence of the specific gaming state. If a predetermined repetition condition is satisfied, the control of the specific gaming state is repeatedly and continuously performed.

[Problems to be Solved by the Invention] However, in this type of conventional pachinko gaming machine, if the repetition condition is satisfied during the second predetermined period associated with the occurrence of the specific gaming state, the current game is stopped. The control associated with the occurrence of the specified game state was discontinued, and a new repeating continuation control of the first state of the variable winning ball device was performed. As a result, the control of the variable winning ball device to the first state due to the occurrence of the specific game state that is currently being carried out is discontinued midway through, and the control of the first state is not effectively utilized until the end. Since the player cannot play the game, there is a risk that the player may feel dissatisfied with the game. The drawback was that the purpose could not be fully achieved.

In view of the above circumstances, the present invention prevents the control of the first state of the variable winning ball device from being interrupted midway due to repeated continuous control, and terminates the first state of the variable winning ball device once generated. To provide a pachinko game machine that can be used effectively up to and fully achieve the original purpose of repeated and continuous control.

[Means for Solving the Problems] A pachinko game machine according to the present invention includes a variable winning ball device that can freely change into a first state that is advantageous to the player or a second state that is disadvantageous to the player. , a first variable prize ball device determined to be able to maintain the variable prize winning ball device in a first state for a first predetermined period during which a relatively small gaming value can be awarded based on winnings of balls hit;
a winning area, a winning ball detection means for detecting a winning ball that has entered the first winning area, and a gaming state that can be generated by a hit ball entering the variable winning ball device, specific gaming state determining means for determining that a predetermined gaming state has been reached so that the variable winning ball device can be in the first state for a second predetermined period during which a relatively large gaming value can be awarded; a repetition condition determining means for repeatedly bringing the variable winning ball device into the first state during a second predetermined period; and a repetition condition storage means for storing that a determination output has been derived from the repetition condition determining means. and, based on the detection by the entered prize ball detection means, the variable winning ball device is controlled to be in the first state for the first predetermined period, and based on the output of the specific game state determination means, the variable winning ball device is controlled to be in the first state. The variable winning ball device is controlled to be in the first state for a predetermined period of time, and after the second predetermined period has elapsed, the variable winning ball device is controlled to be in the first state again if there is memory in the repeating condition storage means. and a game control means for controlling the state.

[Function] According to the present invention, if a hit ball wins in the first winning area, the first state becomes advantageous for the player in a manner in which the variable winning ball device can provide a relatively small gaming value. controlled by. A variable winning ball device for a second predetermined period that can provide a relatively large gaming value if a specific gaming state occurs based on a hit ball that enters the variable winning ball device that is controlled to the first state. is controlled to the first state. In addition, if a predetermined repetition condition is satisfied during the second predetermined period, it is stored that the repetition condition has been satisfied, and the control of the first state of the variable winning ball device that is currently being performed is After the end, the first state is repeatedly and continuously controlled again based on the storage of the repetition condition.

In other words, the repeated continuation control of the first state repeatedly provides the player with the excitement associated with the specific gaming state, and when starting the repeated continuation control, the first state currently being performed is Since the game is controlled so as to wait until the control is finished and then start after that, the game can be played by effectively utilizing the first state of the variable prize winning ball device that has once occurred until the end.

FIG. 3A is a perspective view of an example of a winning ball device,
FIG. 3B is an exploded perspective view of the winning ball device. In the figure, the variable winning ball device 30 includes a decorative frame 31. A rectangular through hole 3 is provided in the center of the decorative frame 31.
11 is formed. This through hole 311 becomes a winning area 32 in which a ball can be won. An opening/closing plate 33 is provided on the front surface of the through hole 311 so as to be openable and closable. On both sides of the opening/closing plate 33, there are U-shaped protrusions 331,
332 is formed. A shaft hole 333 is formed in a part of both the protrusions 331 and 332. Decorative frame 31
A frame member 34 is provided on the back surface of. Frame member 3
A through hole 341 is bored on both sides of 4. The opening/closing plate 33 connects the shaft 35 to the through hole 341 and the shaft hole 3.
33, it is rotatably supported toward the front side. An engagement pin 334 is formed at the tip of the protrusion 332 . Frame member 34 corresponding to protrusion 332 on which engagement pin 334 is formed
An elongated hole 342 is bored in the side wall of. The engagement pin 334 is engaged with a long hole at one end of a lever 364 included in the opening/closing drive mechanism 36, which will be described later, via a long hole 342.

The opening/closing drive mechanism 36 includes a solenoid 361. The plunger 362 of the solenoid 361 has
One end of rod 363 is engaged. Rod 363
The other end is a pin 365 formed on the lever 364.
engaged with. The other end of the lever 364 is connected to the support shaft 3
43. As a result, the solenoid 361 attracts the plunger 362 by its electrical bias, pulls up the rod 363 and rotates the lever 364 upward, thereby opening the opening/closing plate 33. When the solenoid 361 is deenergized, the return force of a spring 366 associated with the plunger 362 causes the plunger 36 to
2 is pulled down. As a result, the opening/closing plate 33 is closed.

Safe holes 37a and 37b are provided on both the left and right sides of the decorative frame 31 as required. The safe holes 37a, 37b accept balls only when the opening/closing plate 33 is open, whereas the safe holes 37a, 37b accept balls even when the opening/closing plate 33 is closed and lead them to the back side as winning balls.

The entry award area 32 is divided into three areas in the horizontal direction as necessary. That is, a winning area 32a through which one ball can pass is formed in the center of the winning area 32, and the winning area 32a on both left and right sides of the winning area 32a is formed in the center of the winning area 32.
b, 32c are formed. This winning area 32a
is used as a special prize area where a predetermined specific condition can be established in response to the winning of a ball during opening of the opening/closing board 33, in other words, a special prize area where a specific gaming state can be generated. . Therefore, in the following explanation, the winning area 32a will be referred to as a special prize area, and the specific gaming state will be referred to as a specific condition. A guide member 38 is provided on the back side of the special prize area 32a in association with the frame member 34. The guide member 38 functions to guide the winning balls into the special prize area 32a to a path 213 shown in FIG. 2.

Furthermore, if necessary, a light emitting diode 39
a and 39b are provided in relation to the decorative frame 31.
However, the decorative frame 31 is transparent. The light emitting diodes 39a and 39b are driven to display in response to the ball landing in the special prize area 32a during the opening operation of the opening/closing plate 33 to notify that a predetermined specific condition has been met.

The variable winning ball device 30 shown in FIGS. 3A and 3B opens the opening/closing plate 33 as an example of a first state that is advantageous to the player, and opens and closes the opening/closing plate 33 as an example of a second state that is disadvantageous to the player. The plate 33 is closed to make it impossible to receive balls. However, the winning ball device to which this invention is applied is not limited to this, and may be a conventionally known winning ball device, such as a chulip, which has a second state in which it is difficult for balls to enter, or a ball device that will be developed in the future. I would like to point out that it can be any of a variety of things.

FIG. 4 is a game control circuit diagram of an embodiment of the present invention. The game control circuit 50 of this embodiment includes a winning ball detection means 22, a special prize ball detector 23 which is an example of a specific condition detection means, a first signal generation circuit 41, a second signal generation circuit 42, a drive circuit 43, and a timer. It includes a changing means 44, a display circuit 45, and an n-ary counter 46, which is an example of a counting means.

The first signal generating circuit 41 is connected to the winning ball detection means 2.
In response to the output of 2, a signal is generated to open the variable winning ball device 30 at least once. The second signal generating circuit 42 generates a variable winning ball again after the variable winning ball device 30 is closed in response to the output of the special prize ball detector 23 during the period when the variable winning ball device 30 is open. device 30
A signal is generated to repeatedly and alternately drive within a certain period of time (for example, a certain number of opening/closing times or a certain opening time, ie, a second predetermined period). The drive circuit 43 opens the variable winning ball device 30 according to the output of the first signal generation circuit 41 or the second signal generation circuit 42. Therefore, the first signal generation circuit 41 and the drive circuit 43 constitute a first drive control means. Second signal generation circuit 4
2 and the drive circuit 43 constitute a second drive control means. Further, the first drive control means and the second drive control means drive the winning ball device to the first state at least once in response to the output of the winning ball detecting means, and the specific condition detecting means A drive control means is configured to continuously and alternately drive the winning ball device to a first state and a second state a plurality of times in response to the output.

When the variable winning ball device 30 is continuously and alternately driven to the first state and the second state multiple times based on specific conditions (i.e., opened/closed driven), the time changing means 44 determines how many times the variable winning ball device 30 is driven open/closed. The opening time of the variable winning ball device 30 is changed depending on the situation. Prior to explaining the operation of this embodiment, the driving conditions of the pachinko machine 10 of this embodiment will be briefly explained. When the hit ball enters the safe hole 13a or 13b, the opening/closing plate 33 of the variable winning ball device 30
is opened only once for a relatively short fixed period of time. When the hit ball enters the safe hole 13c, the variable winning ball device 30 is opened and closed twice. When a hit ball enters the special prize area 32a during opening of the variable winning ball device 30, a specific condition is satisfied. This specific condition is a condition that allows the variable winning ball device 30 to be opened and closed a predetermined number of times (for example, 18 times). As the number of times of opening and closing of the variable winning ball device 30 increases, the opening time per time is increased stepwise or sequentially.

Next, with reference to FIGS. 1 to 4, the operation of this embodiment will be described together with the specific circuit configuration of FIG. 4.

First, the case where the ball hits the safe hole 13a or 13b will be described. In this case, the winning ball detectors 22a and 22b corresponding to the safe holes 13a and 13b in which the winning balls have won derive a high level and provide it to the holding circuit 411 via the OR gate 221.
The holding circuit 411 stores the fact that a winning ball has been won in response to the winning ball detection output, and derives a high level until a reset signal is given from a reset pulse generating circuit 428, which will be described later. This high level is applied to the timer 412 and also to the driver 432 via the OR gate 431. The timer 412 operates in response to the rise of the output of the holding circuit 411, and operates for a predetermined period of time (for example,
0.6 seconds). The driver 432 energizes the solenoid 361 for a certain period of time set by the timer 412. In response, the solenoid 361 attracts the plunger 362 to pull up the rod 363 and rotate the lever 364.
The opening/closing plate 33 is opened. As a result, the variable winning ball device 30 becomes in an open state (that is, a state where it is easy to win a prize). During the opening period of the opening/closing plate 33, if no balls hit into the special prize area 32a, the time-up output of the timer 412 is given to the AND gate 414 via the OR gate 413. At this time, since there is no special prize ball detection output, the holding circuit 421 keeps its output at a low level. The low level is inverted to high level and applied to AND gate 414. Therefore, AND gate 414 derives a high level and applies it to reset pulse generation circuit 428. In response, the reset pulse generating circuit 428 generates a reset pulse for a short period of time to reset the memory holding state of the holding circuit 411. As a result, the opening/closing plate 33 of the variable winning ball device 30 is closed.

Next, the operation when the ball hits the safe hole 13c will be described. In this case, the winning ball detector 22
c derives a high level and supplies it to the holding circuit 416. The holding circuit 416 stores and holds the output of the winning ball detector 22c until a reset pulse is applied, and derives a high level representing the state. This high level is applied as an activation signal to the binary counter 417 and also to the AND gate 434 via the OR gate 433. The output pulse from the frequency divider 443 is applied to the AND gate 434 as the other input. Frequency divider 443 divides the output pulse of slice circuit 444 . In this case, the holding circuit 421
Since the output of the time control circuit 4 is low level, the time control circuit 4
41 indicates that the frequency divided pulse p1 of the frequency divider 443 is, for example,
The period and positive pulse width of the output pulse of the slice circuit 443 are controlled so that the pulse duration is 0.8 seconds. Note that the details of the time control circuit 441 will be described later.

Therefore, the AND gate 434
During the period when the output of 16 is at high level, the frequency division pulse p
1 is derived and given to the driver 432 via the OR gate 431. The driver 432 operates the solenoid 361 in synchronization with the output pulse of the AND gate 434.
is intermittently energized to drive the variable winning ball device 30 to open and close. At this time, during the period in which the activation signal is applied, the binary counter 417 performs a counting operation every time a pulse p1' synchronized with the divided pulse p1 of the output of the frequency divider 443 is applied.
1' is given, a count up output is derived. The count up output is applied to a reset pulse generation circuit 428 via an OR gate 413 and an AND gate 414. Therefore, the reset pulse generating circuit 428 derives a reset pulse with a certain time delay from the rising edge of the frequency-divided pulse p1, and supplies it to the holding circuit 416.
In response, holding circuit 416 releases its stored state and sets its output to low level. In this manner, the holding circuit 416 outputs a high level until the AND gate 434 derives two frequency-divided pulses p1, so the solenoid 361 is intermittently energized only twice. Therefore, the opening/closing plate 33 of the variable winning ball device 30 is driven to open and close only twice.

By the way, as mentioned above, the opening/closing plate 33 is
In the state where it is opened and closed once or twice,
If the ball does not land in the special prize area 32a, the predetermined specific condition will not be detected. In that case, the variable winning ball device 30 based on the detection of specific conditions
No alternating driving operation is performed.

FIG. 5 is a diagram schematically showing the relationship between the count value of the n-ary counter 46 and the opening time of the variable winning ball device 30 based on specific conditions.

FIG. 6 is a waveform diagram of each part for explaining the operation of the time varying means 44. In particular, (a) is when the opening time is T1, (b) is when the opening time is T2, (c) is when the opening time is T3, and (d) is when the opening time is T4. Waveform of output x of sawtooth wave generation circuit 442 and slice circuit 4
44 shows the waveform of output pulse y.

Next, with reference to FIGS. 1 to 6, the operation when changing the alternate driving time of the winning ball device 30 based on the specific conditions that characterize this embodiment will be described. As described above, when the ball hits the special prize area 32a while the opening/closing plate 33 is opening once or twice, a specific condition is detected and the following operation is performed. In other words, the special prize ball detector 2
3 detects the special prize ball and sets the flip-flop 422 with its output. flipflop 42
The set output Q of 2 is given as one input of an AND gate 423. At this time, the holding circuit 421
Since the output of delay circuit 425 is at low level, the output of delay circuit 425 is also at low level, and this low level is inverted and given as the other input of AND gate 423. Therefore, and gate 4
23 derives a high level and supplies it to a holding circuit 421 and a differentiating circuit 424. The differentiation circuit 424 is
Differentiate the rising edge of the specific condition detection output to derive a differentiated pulse. The differential pulse is given to the flip-flop 422 and the n-ary counter 46 as a reset pulse, and is given to the n-ary counter 46 as an addition pulse.
It is given to the advance counter 427. Further, the differential pulse is applied to a reset pulse generation circuit 428. In response, the reset pulse generation circuit 428 derives a reset pulse with a minute time width and outputs the reset pulse to the holding circuit 4.
11, 416 and 421 are momentarily reset. However, since the pulse time width given from the AND gate 427 is longer than the reset pulse time, the holding circuit 421 is
The high level of the output No. 3 (that is, the specific condition detection output) is stored and held, and the output is set to the high level. In this way, at the start of a specific condition, the reset pulse generation circuit 428 controls the holding circuit 411,
The reason why 416 is reset is to give priority to operations based on specific conditions.

The high level of the output of the holding circuit 421 enables the n-ary counter 46 and the display drive circuit 451, disables the AND gate 414, and is further provided as one input of the AND gate 434 via the OR gate 433. In addition, the holding circuit 42
The output of 1 is delayed by a delay circuit 425 for a certain period of time to disable AND gate 423. In this way, the reason why the specific condition detection output is temporarily stored in the flip-flop 422 and the AND gate 423 is disabled while the output of the holding circuit 421 is at a high level is based on the detection of the special prize condition once. This is because when the opening/closing drive is repeated for a fixed number of times, when a special prize ball is generated again, it is stored and the opening/closing drive is repeated again after completing the repeated opening/closing drive for a fixed number of times.
The special prize ball detector 23 constitutes a repetition condition determining means for repeatedly bringing the variable winning ball device into the first state during the second predetermined period. In addition, the flip-flop 422
This constitutes a repetition condition storage means that stores information that a determination output has been derived from the repetition condition determination means. This repeated continuous control and the first repeated opening/closing drive control are performed when a predetermined specific combination is established between the detection output from the special prize ball detection means and the display result of a separately provided digital display. Control may be started when the condition is established. Further, the specific conditions and the repetition conditions may be different. For example, winning area 32
b, 32c or Yakumono 14a, 14b may be repeated as a condition.

The n-ary counter 46 is activated while the output of the holding circuit 421 is at a high level, and counts the pulse p1 given from the frequency divider 443. In other words, the n-ary counter 46 counts the number of times the variable winning ball device 30 is alternately driven in the first state and the second state (the number of times it is repeatedly opened and closed). In this embodiment, for example, 18
The variable winning ball device 30 can be opened and closed only once. The count value of this n-ary counter 46 is calculated by the time changing means 44.
is applied to a time control circuit 441 included in the.
Now, assuming that the count value of the n-ary counter 46 is 5 or less, the opening time of the variable winning ball device 30 is T.
1=0.3 seconds. However, in this embodiment, the closing time of the variable winning ball device 30 in the alternate drive operation is constant (for example, Tc = 0.8 seconds) regardless of the count value of the n-ary counter 46. Time control circuit 4
41 controls the oscillation frequency of the sawtooth wave generation circuit 442 so that the period becomes F1 based on the count value of the n-ary counter 46 being 5 or less. In this way, in order to change the frequency of the sawtooth wave, the sawtooth wave generation circuit 442 is configured with a voltage controlled oscillator, and the voltage control output thereof is changed based on the count value of the n-ary counter 46. good. Output x of sawtooth wave generation circuit 442
is applied to slice circuit 444. The slice circuit 444 is given a signal from the time control circuit 441 for determining the slice level L1.
Therefore, the slicing circuit 444 slices the sawtooth wave at level L1 and derives the pulse y.
Note that a level discrimination circuit may be used in place of the slice circuit 444. If the frequency division ratio of the frequency divider 443 is dd, the high level time of the pulse y is T.
It becomes 1/d. Therefore, the pulse frequency-divided by the frequency divider 443 is applied to the driver 432 via the AND gate 434 and the OR gate 431. This causes the driver 432 to
The solenoid 3 has a cycle of Tc and a time T1.
61 is electrically energized. As a result, the opening/closing plate 33 of the variable winning ball device 30 is opened for an opening time T1 (=0.3 seconds)
and is driven to open and close alternately five times with a closing time Tc (=0.8 seconds). And the n-ary counter 46
If the count value is 6 or more and 10 or less, the opening time is T2 (=0.5 seconds) and the closing time is
It is driven to open and close alternately so that Tc (=0.8 seconds). In that case, the time control circuit 441 controls the oscillation period of the sawtooth wave generation circuit 442 to F2 (however, F2>F1), and the slice circuit 444
Set the slice level to L2 (L2<L1)
This is done by controlling the

Similarly, when the count value of the n-ary counter 46 is 11 to 15, the time control circuit 441 controls the period of the sawtooth wave generation circuit 442 to F3, and the slice level is set to L3 (in this case, the opening time and the closing time). Since the times are equal, by controlling L3=0), the opening time of the variable winning ball device 30 becomes T3(=
0.8 seconds) and the closing time is Tc (=0.8 seconds).

Furthermore, if the count value of the n-ary counter 46 is 16 or
18, the time control circuit 441 controls the period of the sawtooth wave to F4 and the slice level to -L4.
By controlling the variable winning ball device 30, the opening time is T4 (=2 seconds) and the closing time is
The drive is controlled alternately so that Tc.

Therefore, according to this embodiment, when the variable winning ball device 30 is alternately and repeatedly driven to open and close based on one specific condition, the opening time is changed in stages according to the increase in the number of repeated opening and closing drives. It can be controlled so that it becomes longer. However, the n-ary counter 46
The product of the opening time for each count value and the number of times, that is, the time that can be opened based on one specific condition is:
This is a legally regulated fixed period of time (for example, 30 seconds).
Further, the alternating driving time of the variable winning ball device 30 may be configured to change depending on the number of winning balls to the variable winning ball device 30. Furthermore, the alternating driving time can be changed (longer or shorter) by satisfying the condition that the earlier of the winning of a predetermined number of balls to the variable winning ball device 30 or the opening and closing of the variable winning ball device 30 a predetermined number of times is satisfied. ) may be done.

By the way, in the above embodiment, in order to change the alternate driving time of the variable winning ball device 30 based on the count value of the n-ary counter 46, the sawtooth wave generation circuit 442 and the slice circuit 444 are provided, and the oscillation frequency of the sawtooth wave is changed. Although the case where the slice level is changed has been described, the opening time is not limited to this, and the opening time may be changed by various means. For example, you can keep the slice level constant and change only the frequency, or keep the frequency constant and change only the slice level, or generate a clock pulse at a constant frequency and change the division ratio for dividing the clock pulse. Various methods can be considered, such as a method to
Furthermore, in the above-described embodiments, a case has been described in which the closing time is constant and the opening time is varied, but both the closing time and the opening time may be varied.

Then, when the count value of the n-ary counter 46 reaches a certain number (for example, 18), a count-up output is derived. The count up output is provided to a reset pulse generation circuit 428. In response, the reset pulse generating circuit 428 derives a reset pulse, and the holding state of the holding circuit 421 is released. Therefore, the output of the holding circuit 421 becomes low level and the AND gate 434 is disabled, so that the alternate opening and closing operation of the variable winning ball device 30 is thereafter completed. In addition, the variable winning ball device 30 is configured to alternate between winning a fixed number of pachinko balls to the variable winning ball device 30 or opening and closing the variable winning ball device 30 a certain number of times, whichever comes first. The opening/closing operation may be controlled to end.

By the way, as mentioned above, during the period when the variable winning ball device 30 is being driven to open and close based on the specific conditions, at least one hit ball is in the special prize area 32a.
When a prize is won, the special prize ball detector 23 detects it and sets the flip-flop 422.
Therefore, in this case, after the completion of the repeated opening/closing operation based on the previous specific conditions, the AND gate 423 is opened again after a certain period of time set by the delay circuit 425.
derives the high level. As a result, the repeated opening/closing operation based on the specific conditions is performed again. In this way, the possible number of alternate driving based on the specific conditions is determined to be eight times, for example. In that case,
As the m-ary counter 427, an octal counter is used. Then, the count value of the m-ary counter 427 is given to the decoder driver 452. The decoder driver 452 displays the count value of the m-ary counter 427 on the segment display 453. Also,
The count value of the m-adic counter 427 is given to the special prize state prohibition circuit 426. Special prize state prohibition circuit 426
includes a circuit that detects that the count value of the m-adic counter 427 has reached a permissible constant number (8), and a circuit that generates a prohibition signal based on the detection output.
Then, when the count value of the m-adic counter 427 reaches a certain number, the special prize state prohibition circuit 426 disables the holding circuit 429 from now on, and performs alternate driving in accordance with the detection of a special prize ball, for example. prohibited. In this way, if the number of operations based on specific conditions is limited to a certain number, there is an advantage that the game center can be prevented from being disadvantaged undesirably. The game control circuit 40 controls the variable winning ball device to be in the first state for the first predetermined period based on the output of the winning prize ball detection means, and controls the variable winning ball device in the first state for the first predetermined period based on the output of the specific game state determining means. The variable winning ball device is controlled in the first state for the second predetermined period, and after the second predetermined period has elapsed, the variable winning ball device is controlled again if the repeating condition storage means has a memory. A game control means is configured to control the ball device to a first state.

In addition, although the above-mentioned embodiment shows the case where the game control circuit 40 is configured by a hardware circuit, it is possible to configure the game control circuit 40 by using a microprocessor by assembling a program to perform the same operation as in this embodiment. Similar operations can also be performed by software processing.

[Effects of the Invention] According to the present invention, by repeating and continuing control, it is possible to repeatedly and continuously make the player experience the great excitement that accompanies the provision of a relatively large gaming value, giving the player a great sense of satisfaction. Moreover, since the first state of the variable winning ball device once generated is continued until the end without being discontinued midway due to repeated continuation control, the first state is valid until the end. It has now been possible to provide a pachinko game machine that can fully achieve the original purpose of repeated continuous control, which is to provide a great sense of satisfaction, without giving the player a sense of dissatisfaction. .
