Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a variable prize winning device for a pachinko machine.

[Prior Art] Conventionally, this type of pachinko machine is known to be equipped with a variable prize winning device, an opening/closing drive command signal generation means, an opening/closing drive means, and a stop control means (for example, Japanese Patent Laid-Open No. 78975/1983). Publication No. and JP-A-56-
Publication No. 85376).

[Problems to be Solved by the Invention] However, in conventional pachinko machines, when a specific gaming state is achieved, the variable winning device is repeatedly opened and closed for a predetermined time or until a predetermined number of winning balls are generated. Therefore, there was a problem that the conversion conditions of the variable prize winning device were simple and did not vary much.

In other words, in conventional pachinko machines, the variable winning device closes when a predetermined time elapses or a predetermined number of winning balls are generated, so a specific gaming state is not achieved. After that, you don't have to demonstrate your gaming skills anymore, you just wait for a predetermined number of winning balls to win, and everyone receives almost the same benefits, lacks a sense of thrill and tension, and has no profit. It ends up being a game with no hope for expansion.

In addition, if a predetermined number of winning balls do not occur within a certain period of time, the repeated opening/closing operation of the variable winning device is extended and controlled, but in this case, the predetermined number of winning balls is guaranteed. The game becomes even less thrilling and tense.

Therefore, the present invention is intended to solve the above-mentioned conventional problems, and its purpose is to provide a thrilling and tense experience, to have fun in which one can gradually expand the benefits that one can receive, and to provide a continuous experience. By limiting the maximum number of times a game can be played, it is possible to maintain a balance between the profits of the gaming parlor and the profits of the players, while also preventing profits from being unevenly distributed to a very limited number of players. By setting benefit conditions that are relatively difficult to achieve, we provide the opportunity to increase the maximum number of continuations, and if we are lucky enough to achieve this benefit condition, we aim to further expand the benefits that we can receive. It is an object of the present invention to provide a pachinko machine that is rich in variety and can give a sense of expectation and a sense of accomplishment as well as a sense of satisfaction from the profits obtained.

[Means for Solving the Problems] Therefore, the present invention is aimed at achieving the above object, and the contents thereof will be explained below using embodiments shown in the drawings.

The present invention includes a gaming section 7 surrounded by guide rails 5, and a first
a variable prize winning device 13 having at least a continuation opening 28 that can convert the state into a second state advantageous to the player, and in which the received batted ball can win a prize; A variable prize winning device is set in advance based on a specific gaming state detection means (for example, the discrimination circuit 44) that detects a specific gaming state achieved based on a hit ball, and a specific gaming state detection signal from the specific gaming state detection means. A conversion drive control means (for example, a flip-flop 49a, a timer 55a, etc.) converts the game into a second state advantageous to the player according to predetermined conditions, and a batted ball that enters the continuation slot of the variable winning device. a continuation condition detection means (for example, the special switch 31) that detects a continuation condition, and a privilege condition detection means (for example, a special switch 31) that detects a privilege condition that is achieved based on a ball fired into the gaming section and is more difficult to achieve than the continuation condition. For example, bonus switch 33)
and a continuous drive in which, based on the continuous condition detection signal from the continuous condition detection means, the conversion drive control means repeatedly converts the variable prize winning device into a second state advantageous to the player according to predetermined conditions. The control means (for example, the flip-flop 58, etc.) counts the number of continuations by the continuation drive control means, and when the number of continuations reaches a preset maximum number of continuations, a continuation condition detection signal is sent from the continuation condition detection means. Regardless, the maximum number of consecutive times regulating means (for example, the N-ary counter 6
2, etc.), and a benefit grant control means for increasing the maximum number of continuations preset in the maximum number of continuations regulating means in accordance with preset profit conditions based on a benefit condition detection signal from the benefit condition detection means. (for example, AND gate 63, etc.);

[Operation] Therefore, when a specific gaming state is detected by the specific gaming state detection means 44, the conversion drive control means 49 and the like operate the variable winning device 13 under predetermined conditions set in advance based on the specific gaming state detection signal. Accordingly, the state is converted to a second state advantageous to the player.

Then, while the variable prize winning device 13 is converting to the second state advantageous to the player, the continuation condition is detected by the continuation condition detection means 31 based on the hit ball that has won in the continuation slot 28 of the variable prize winning device. Then, based on the continuation condition detection signal, the continuation drive control means 58 etc.
The conversion drive control means repeatedly converts the variable prize winning device into a second state advantageous to the player according to predetermined conditions.

The number of continuations is counted by the maximum number of continuations regulating means 62, etc., and when the count reaches the preset maximum number of continuations, regardless of the continuation condition detection signal from the continuation condition detection means, the conversion drive control means to put the variable prize winning device into a first state disadvantageous to the player.

While the variable winning device 13 is converting to the second state advantageous to the player, if no ball enters the continuation slot of the variable winning device and the continuation condition is not detected by the continuation condition detection means, the continuation condition is not detected. cannot receive the benefits of

On the other hand, when the privilege condition detecting means 33 detects a privilege condition that is more difficult to achieve than the continuation condition based on the ball hit in the gaming section, the privilege granting control means 63 and the like increase the maximum number of continuations preset in the maximum number of continuations regulating means in accordance with preset profit conditions.

[Example] The present invention will be described below based on an example shown in the drawings.

In FIG. 1, a pachinko machine 1 has a ball supply tray 2 on its surface, and when a player puts a ball into the supply tray 2 and operates the operating section 3, a firing device 4 is activated, so that the ball is sent to the supply tray 2. The balls you put in are fired one after another.

The fired ball is guided above the game part 7 on the surface of the game board 6 through the guide rail 5, and flows down the game part 7 while hitting an obstacle nail. And, if you enter 8 winning holes on the way down, it will be safe.
A prize ball discharging mechanism (not shown) provided on the back side of the game board 6 is operated, and a certain number of prize balls are discharged into the supply tray 7 or the receiving tray 2' provided below the surface of the Pachinko machine 1. However, if the batted ball flowing down the gaming section 7 does not enter any of the winning holes 8, it enters the out opening 9 provided at the lower end of the gaming section 7 and is confiscated.

In the gaming section 7 described above, a first condition to be achieved by hitting a ball is set. According to the embodiment of the drawings, the first condition is that the ball enters either the left or right specific winning openings 10a, 10b provided above the gaming section 7, or that the ball enters the specific winning openings 10a and 10b provided below the gaming section 7. This is achieved by the ball passing through the frame 10c.
Since it is preferable that this first condition is not easily achieved, the specific winning openings 10a and 10b are
It is preferable to make it difficult for a batted ball to enter the special winning slot 10c or to make it difficult for a batted ball to pass through the specific prize winning slot 10c. In addition, a switch mechanism faces each of the specific winning slots 10a, 10b and the specific winning slot 10c, and when a batted ball enters or passes through, the switch mechanism is momentarily turned on and detects that the first condition is met.

As mentioned above, if the batted ball happens to enter either of the specific winning slots 10a, 10b or the specific winning slot 10
When the first condition is achieved by passing step c, another game is started by the electric control device.

According to the embodiment shown in the drawings, this separate game is played by rapidly changing the three variable displays 11a to 11c. These variable indicators 11a to 11c
may be performed mechanically, for example by rotating a drum or disk at high speed, displaying 10 numbers from 1 to 0, or by displaying a segmented display of 7 segments arranged in a diagonal pattern. This may be done by electrically controlling the device to rapidly change the numbers from 1 to 0.

In any case, if the ball meets the first condition,
A separate game is started by the variable display, and this separate game continues for a predetermined period of time (for example, 7 seconds).

If the player operates the stop switch 12 on the surface of the pachinko machine within this predetermined time, the high-speed changes of the variable indicators 11a to 11c will stop in sequence, and any number from 1 to 0 will be displayed in the window. . Further, if the player does not operate the stop switch 12 within a predetermined time during another game, the high-speed change of each variable display 11a to 11c will be stopped in sequence by the timer of the electric control device immediately after the predetermined time ends. , the state is the same as when the player operates the stop switch 12.

As a result of completing another game in this way, when a specific game state is achieved, a special game will start and there will be a chance to bring great profits to the player.
If a specific gaming state is not achieved, only a small profit can be brought to the player.

The above-mentioned specific game state corresponds to, for example, a case where all the numbers "7" are aligned and stopped in the window holes of each variable display 11a to 11c, and in other cases, the specific game state is not achieved.

In the special game, in the embodiment shown in the drawings, the variable prize winning device 13 provided in the game section 7 does not accept the batted ball, or is difficult to accept the batted ball, and easily accepts the batted ball from the first state, which is disadvantageous to the player, and is advantageous to the player. This is performed by converting to the second state and continuing this state under preset conditions, for example, for a certain period of time (30 seconds).

The variable prize winning device 13 in this embodiment has a horizontally elongated opening 14, and guide pieces 15a and 15b are provided at a certain distance below the opening 14 on the left and right sides, and guide pieces 15a and 15b are provided on the upper left and right sides of the opening 14 for assistance. Guide pieces 16a and 16b are provided.

The guide pieces 15a and 15b described above are connected to the game board 6.
It is connected to electromagnets 17a and 17b provided on the back side of the. That is, the rod 1 of each electromagnet 17a, 17b
Connect the tips of 8a and 18b to actuating rods 19a and 19b.
Pins 22a, 22 of swing rods 21a, 21b, which are pivoted at their base ends and pivoted at their base ends to operating frames 20a, 20b provided at the tips of the operating rods 19a, 19b.
b, and the support pins 23a, 23b provided at the tips of the rotating rods 21a, 21b are attached to the game board 5.
This support pin 23a,
Guide pieces 16a, 16b are attached to the protruding ends of 23b, and these support pins 23a, 23b pass through arcuate holes 24a, 24b.

In the configuration of the back side of the pachinko machine 1 described above,
When the electromagnets 17a and 17b are in a demagnetized state, the support pins 23a and 23b are located at one end of the arcuate holes 24a and 24b, and the guide pieces 15a and 15b are located below the opening 14 and spaced apart from each other. Therefore, the batted ball flowing down the gaming section 7 cannot enter the opening 14, resulting in the first situation disadvantageous to the player.

On the other hand, when each electromagnet 17a, 17b is energized, the rods 18a, 18b are attracted, and the rotating rod 21 is rotated by the rotation of the operating rods 19a, 19b.
Each guide piece 15a, 15 at the tip of a, 21b
b moves along the arcuate holes 24a, 24b, and each guide piece 15a, 15b is located at the lower edge of the opening 14 (dashed line in FIGS. 2 and 3). This state is the second state that is advantageous to the player. In this second state, the hit ball flowing down the gaming section 7 rides on the guide pieces 15a, 15b and rolls into the opening 14, becoming a safe ball.

Therefore, the special game starts when each electromagnet 17a, 17b is excited, and the electromagnet 17
When the electromagnets 17a and 17b are demagnetized, each guide piece 1 is energized by the force of a spring (not shown) or by its own weight.
5a and 15b return to their original states.

The auxiliary guide pieces 16a, 16b, like the guide pieces 15a, 15b, are attached to auxiliary actuating rods 26a, 26b and auxiliary turning rods 27a, 2 to auxiliary electromagnets 25a, 25b provided on the back side of the game board.
7b, auxiliary electromagnets 25a, 25
b is demagnetized, each auxiliary guide 16a, 16
Both openings 1 and b are located at the top of the opening 14, but when the auxiliary electromagnets 25a and 25b are energized, each opening 1
Located on the side edge of 4. This auxiliary guide 16a, 1
The action of 6b will be described later.

As described above, in this embodiment, when a specific game state is achieved by another game, the electromagnets 17a, 17
b is excited, and each guide piece 15 is attached to the lower side of the opening 14.
a, 15b are positioned to change the state to a second state where it is easy to accept a batted ball, and a special game is started, and the batted balls flowing down the game section 7 continuously enter the opening 14 and become safe balls.

The opening 14 has at least a continuation opening 28 into which a batted ball can enter relatively easily, a bonus winning opening 29 into which it is difficult for a batted ball to enter, etc.
When the ball that has entered the continuation port 28 enters the continuation port 28, the ball flows down the special flow path 30 and is detected by a special switch 31 as continuation condition detection means.

When the special switch 31 detects a ball flowing down the special channel 30, a second special game starts based on conditions such as that the special game has elapsed for a certain period of time.

That is, the electromagnets 17a and 17b, which were energized based on the achievement of the special conditions when a batted ball enters the continuation port 28 during the special game, are energized again immediately after being demagnetized, and the second special game is started when the predetermined conditions are met. repeated under.

If a ball enters the continuation slot 28 during the second special game, the third special game is repeated after the second special game ends.

Therefore, if the continuation condition is achieved during a certain period of time, the special game will be repeated many times.

However, if the continuation condition is not achieved by a batted ball that enters the opening 14 during a special game within a certain period of time, the special game ends when the special game ends. As a result, the player has no chance to increase profits in the special game.

In this way, if the ball hits the first condition in the game section, a separate game will occur, and if a preset specific game state is achieved in the separate game, this is a special game that gives the player a chance to make a significant profit. The special game starts, and if the continuation condition is achieved during the continuation of the special game for a certain period of time, the special game is repeated again after the special game ends.

Therefore, as long as the continuation conditions are met, the special game will be repeated as many times as necessary, resulting in extremely large profits for the players, making it impossible to maintain a balance between the profits of the pachinko game parlor and the profits of the players.

Therefore, a special game mode is configured in which the special game is repeated a preset number of times (for example, 10 times or 5 times) at the maximum, and if the special game is repeated this maximum number of times, even if the continuation condition is achieved, the special game is The special game mode is ended by restricting the game from being repeated.

However, if the ball hit during the special game achieves a bonus condition that is more difficult to achieve than the continuation condition, the preset profit conditions, such as the number of continuations of the special game that has been played so far, will be initialized and a new one will be played. A special game mode is generated and the special game is played again from the first time, thereby increasing the maximum number of continuations.

The above privilege condition is such that during a special game, the ball happens to enter the privilege winning hole 29 and flow down the privilege channel 32, and the privilege switch 33 as a means for determining the privilege condition is activated.
This is achieved by being detected. Incidentally, an obstacle nail 34 is planted in front of the bonus winning hole 29 to make it difficult for the ball to enter, thereby making it more difficult to achieve the bonus condition compared to the continuation condition.

Next, explanation will be made using the control block diagram shown in FIG.

The batted ball flowing down the gaming section 7 enters the specific winning hole 10a,
10b, or when the first condition is achieved by passing through the specific winning slot 10c, each winning slot 10a,
Detector 1 facing 10b or winning slot 10c
Either output of 0a'...10c' is OR gate 35
is input to the register 36, and the flip-flops 37a to 37c are set.

As a result, each flip-flop 37a to 37
The Q output of c becomes a high level from a low level, and these high level signals are individually connected. Since it is given to one input of AND gates 38a to 38c,
Every time there is a signal from each oscillator 39a-39c, a check signal is input to decimal counters 40a-40c.

Upon receiving this check signal, each decimal counter 40a to 40c transmits an output of 1, 2,...9, 0 at a speed corresponding to the frequency of each oscillator, and this output is sent to a variable display via a driver. 11a-11
given to c.

Therefore, each of the variable indicators 11a to 11c changes rapidly with the numbers 0 to 9 invisible.

This state is a separate game, and this separate game continues for a certain period of time (for example, 7 seconds).

When the player operates the stop switch 12 within a certain period of time, this separate game is input to the reset side of the flip-flop 37c via the OR gate 41. When input to the reset side, the Q output of the flip-flop 37c becomes low level, so the AND gate 38c whose input is connected to this Q output
is closed, decimal counter 40c is AND gate 38
c stops at the number it was counting just before closing,
The variable display 11c is in a state where the number is displayed.

On the other hand, since the output becomes a high level due to the state reversal of the flip-flop 37c, the timer 42b connected to this output operates, and when a predetermined time elapses, for example, 1 second, a high level output is generated. .

Since this output is given to the reset input of the flip-flop 37b, the decimal counter 40b is stopped by the same effect as the flip-flop 37c, and the number is displayed on the variable display 11b, and the output of the flip-flop 37b is Another timer 42a is activated by reversal. The output of this timer 42a is the remaining flip-flop 3.
Since it is connected to the reset input of the timer 7a, when the required time set in the timer 42a, for example 1 second, has elapsed, the high level output generated by the timer 42a causes the state of the flip-flop 37a to be reversed as well. Therefore, as before, the decimal counter 40a
counts a certain number and stops while outputting, so the corresponding variable display 11a also displays that number and stops.

A timer 43 is connected to the Q output of the flip-flop 37c, which is first reset by the operation of the stop switch 12, and this output is connected to the OR gate 4.
1 to the reset input of the flip-flop 37c, the timer 4 is connected at the same time as the flip-flop 37c is set.
3 is in operation. After a certain period of time set in the timer 43 has elapsed (for example, after 7 seconds), the state of the flip-flop 37c is forcibly reversed, causing the above-described circuit operation. This is caused by the player inadvertently or intentionally turning on the stop switch 1.
Even if 2 is not pressed, the circuit system including the counter is returned to the initial state after the set time of the timer 43 has elapsed, in other words, the other game is ended.
If the timer 43 were not provided, another game would continue unless the stop switch 12 is operated.

As described above, each decimal counter 40a to 40
When c outputs a predetermined count value and stops,
The binary coded decimal output, that is, each 4-bit output having a weight of 1-2-4-8, is input to a comparator or discriminator 44 as a means for detecting a specific game state by a combination of ordinary matching circuits.

This discriminator 44 emits first, second, and third outputs. For example, the first output 45a is a decimal value such that all counter outputs are a predetermined decimal value, such as "7".
(all three digits on the display are set to "7"), the second output 45b is output to the counters 40c and 40b.
The decimal value of the output of only is the same (i.e. variable display 1
If only 1c and 11b are the same numbers (such as "1" and "1", "4" and "4", etc.), the third output 45c is transmitted in other cases.

When the first output 45a is issued, indicating the start of a special game, this output is applied to one input of an AND gate 46a, the other input of which is the flip-flop 37a that is last reset with respect to the counter. connected to the output. Therefore, the AND gate 46a is opened and a high level is applied to one input of the other AND gate 48a via the OR gate 47. This AND gate 48
The other input receives the Q output of a flip-flop 49a which is a component of the conversion drive control means whose set input is connected to the output of the AND gate 48a, so the AND gate 48a takes an AND and the flip-flop 49a is inverted. to set the Q output to a high level.

Of course, at the same time, the Q output of the flip-flop 49a becomes low level, so the AND gate 48a that set the flip-flop 49a is closed at this point.

When flip-flop 49a is set in this manner, a high level Q output is applied to one input of three-input AND gate 50a.

On the other hand, the other input, which is the inverting input of this AND gate 50a, is connected to the AND gate 50a.
From the most significant bit (No. 3) of the shift register 51a, which has a 4-bit parallel output terminal (numerals 0, 1, 2, and 3 are assigned from the least significant one for convenience), the clock input is connected to the output of the shift register 51a. Since the shift register 51a which is receiving feedback and whose input is an inverting input has been previously inverted and reset by the low level Q output of the flip-flop 49a in the non-set state, the AND gate 50a is
is determined by the remaining input.

And the last input of the AND gate 50a is
Since the output of the oscillator 52, which generates a high-level pulse signal at an appropriate frequency, is connected, the output of the AND gate 50a becomes high level according to this frequency, and each time the shift register 51a changes the output to "1", one bit at a time. ” or raise it to a high level. This continues until the most significant bit (No. 3), and in this process, the driver 54b operates via the OR gate 53a at the No. 1 output, and the electromagnet 17a is excited. Then, with a slight delay, the driver 54c is activated via the OR gate 53b due to the high level transition of the No. 2 output, and the electromagnet 17b is excited. Further, when the No. 3 output becomes high level, the inverting input of the AND gate 50a is inverted, so the AND gate 50a is closed, and the shift register 51a stops with the most significant bit becoming "1".

Therefore, both electromagnets 17a and 17b continue to be excited, so that each guide piece 15a and 15b closes to the opening 1.
4, the variable prize winning device changes to the second state advantageous to the player, and a special game starts.

It is the timer 55a, which is a component of the conversion drive control means, that is activated by the high level transition of the No. 3 output of the shift register 51a, which ends the continuation of this special game after a certain period of time.

That is, after the timer 55a is activated (electromagnet 17a,
17b) for a set period of time (e.g. 30
seconds), a high level output is emitted. This output is given to one input of an AND gate 56a whose output is connected to the reset input of the flip-flop 49a, and the other input of the AND gate 56a is already at a high level at this point due to the feedback of the Q output of the flip-flop 49a. Therefore, both inputs can be ANDed, and the flip-flop 49a is reset by the output of the gate 56a. At the same time as this reset, the reset AND gate 56a is closed and returns to its original state.

By resetting the above flip-flop 49a, the shift register 51a, which inverts the Q output and uses it as a reset input, is reset, and all bits become 0 or low level. As a result, the shift register 51a also returns to its initial state, so both electromagnets 1
7a and 17b are demagnetized and the special game ends.

In addition, the fixed time during which the special game continues in the example is the set time (30 seconds) of the timer 55a plus the operating time of each circuit (shift time, etc.), but the operating time of each circuit is is negligible compared to the set time of the timer 55a, so both electromagnets 1
It is recognized that the excitation time of 7a and 17b (the fixed time during which the special game continues) is determined by the timer 55a.

As described above, when the detectors 10a' to 10c' are turned on, the decimal counters 40a to 40c are stopped by operating the stop switch 12 or counting up the timer 43, and the output numbers are all set to "7" (i.e. Weight output of 1-2-4 is "1" and output of weight 8 is "0") Both electromagnets 17a and 17b are energized and until demagnetized after 30 seconds, that is, one cycle operation of one special game. is concretely understood.

However, if the batted ball that entered the opening 14 during this one-cycle operation continues enters the continuation port 28, flows down the special flow path 30, and turns on the special switch 31 as a continuation condition detection means, the continuation condition is not achieved. Therefore, both electromagnets 17a and 17b are excited again for 30 seconds as the predetermined condition, and the special game is repeated.

That is, the Q output of the flip-flop 49a before being reset by the timer 55a is applied to the other input of the AND gate 57, which has the output of the special switch 31 as one input. Therefore,
When the special switch 31 is turned on while both electromagnets 17a and 17b are on, the AND gate 57 opens.
A flip-flop 58 is set as a component of the continuous drive control means. This flip-flop 58 is connected to the next electromagnet 17a, 17.
In the storage circuit until the information on the excitation operation of b arrives, a signal for exciting both electromagnets 17a and 17b is sent as a high level Q output to one input of the AND gate 59 and kept on standby.

Then, the first special game ends after a certain period of time (30 seconds) and the AND
When the output of gate 56a goes high, one-shot multivibrator circuit 60 emits one pulse, which is applied to AND gate 59. Therefore, the AND gate 59 receives the high level signal of the flip-flop 58, which is already on standby as described above.

If this happens, the same operation as that based on the first output 45a from the discriminator 44 described above will start, and therefore the time set by the timer 55a will be determined as when both electromagnets 17a and 17b achieve the predetermined condition. The special game is repeated by energizing only.

The output of the OR gate 47 resets the flip-flop 58 via another OR gate 61, and the reset flip-flop 58 is activated when the continuation condition is achieved during repeated special games and the special switch 31 is turned on. This means that you will remember the signal you received when the signal occurred.

On the other hand, if the continuation condition is not achieved, since there is no signal from the special switch 31, all the circuits return to their original state after the special game ends.

Further, in the figure, 62 is an N-ary counter 62 as a means for regulating the maximum number of special games. The flip-flop 58, which serves as a special switch signal storage circuit, is reset via the OR gate 61 by the high signal. The N-ary counter 62 counts once from the basic unit of the first special game, and counts this basic unit 10 times.

Therefore, the carry signal from the N-ary counter 62 is not output until the 9th basic unit, so every time an output is output from the special switch 31 for each special game, the flip-flop 58, which is a memory circuit, memorizes this fact. When the special game ends, the next special game is played. However, when the 10th special game is played, the N-ary counter 62 continues to issue a carry signal to keep the reset input of the flip-flop 58 at a high level.
Even if there is an output from flip-flop 5
The Q output of 8 is pulled to a low level. Therefore, even if there is an output from the special switch 31 during the continuation of the special game, that is, even if the continuation condition is achieved, it is equivalent to no output from the special switch 31, and the 11th special game will not occur.

In order to cause such an operation, the N-ary (decimal) counter 62 requires the following conditions.
That is, it is necessary that the count be reset before the first count of the start of the special game, and that the count must be incremented by "1" every time the special game is played.

First, the reset of the counter 62 is based on the first output 45 of the discriminator 44, which is the starting condition for the first special game.
The special game is repeatedly counted using the time-up signal (signal to the AND gate 56a) of the timer 55a, which is activated after the electromagnets 17a and 17b are excited, as input to the counter.

Therefore, before the first start of the special game, the N-ary counter 62 is reset by the first output 45a, the special game is repeated 10 times, and the timer 55a is reset.
When the signal is given 10 times, a carry signal is issued to reset the flip-flop 58, so the 11th special game is not played.

Also, during a special game, the ball you hit just happened to be in the bonus winning slot 2.
9, when the benefit condition is detected by the benefit switch 33 as a benefit condition detection means, the benefit condition is achieved;
From the privilege switch 33 as a privilege grant control means
An output is given to AND gate 63. AND gate 6
3 receives the Q output from the flip-flop 49a, so it opens when receiving the output from the bonus switch 33 during a special game where the Q output is at a high level, and the AND output passes through the OR gate 64 to the N-ary counter 62. Reset. When the N-ary counter 62 is reset, the first output 45a from the discriminator 44
It returns to the same state as when it was received, ie, the initial state of achieving the special gaming state.

Therefore, the N-ary counter 62 starts counting again from the first time, and when it receives the signal from the timer 55a ten times, it issues a carry signal to reset the flip-flop 58.

In addition, for convenience during maintenance and inspection,
A monitor switch 65 is provided on the back of the pachinko machine, and when operated, each decimal counter 40a to
The output of this switch is put into the preset input of each decimal counter so that all 40c output the decimal number "7". However, each detector 10a' to 10
The flip-flops 37a to 37c, which operate the respective counters 40a to 40c when c' is turned on, can be monitored only when they are all in the reset state. AND with the Q outputs of the corresponding flip-flops 37a to 37c.
AND gates 66a to 66c are provided.

The explanation up to this point has been based on the case where the first condition is achieved by hitting a ball and a separate game is started, and in this separate game, a specific game state is achieved and a special game occurs, and the first output 45a is transmitted from the discrimination circuit 44. This makes everything work.

However, if the first profit game occurs without achieving the specific game state in another game, that is, the counters 40a and 4 of the decimal counters 40a to 40c
A case will be described in which the discriminator 44 issues the second output 45b when the decimal values of only 0b are present.

In this case, the profit level for the player is much lower than that of the special game, and the second output 45
b and the output of the flip-flop 37a, which has been reset as explained above, is
The AND output is taken by AND gate 46b, and the AND output is given to one input of another AND gate 48b. Since the other input of this gate 48b receives the Q output of the flip-flop 49b which uses this gate output as the set input, the AND gate 48b is also opened, and the flip-flop 49b is opened.
9b is set and the Q output becomes high level. At the same time, the output becomes low level and the AND gate 48
b is closed.

On the other hand, the Q due to the setting of flip-flop 49b
The output high level signal is three inputs with one inverting input.
to one non-inverting input of AND gate 50b;
The inverting input receives the most significant bit output of a shift register 51b which has a 4-bit parallel output terminal that receives the output of this gate 50b as a clock, and since this output is at a low level, it ends up being connected to the remaining non-inverting input. Every time the output of the oscillator 52 is input, the AND gate 50b passes it through, and the shift register 50b sequentially sets the parallel bit output from "1" to high level from LSB to MSB.

As a result, the auxiliary electromagnet 25a is excited via the driver 54a, then the electromagnet 17a is excited via the OR gate 53a and the driver 54b, and then
The electromagnet 17b is excited via the OR gate 53b and the driver 54c, and finally the auxiliary electromagnet 25b is excited. And shift register 51
If b follows and the MSB output is “1”,
This output closes the AND gate 50b and the output of the oscillator 52 is no longer given to this register 51b, so each electromagnet 25a, 17a, 17b, 2
5b is continuously excited.

This state is the mode of the first profit game, and when each electromagnet 17a, 17b, 25a, 25b is excited, the guide pieces 15a, 15b are located at the lower side of the opening 14 as described above, and the auxiliary guide piece 1
6a and 16b are located on the left and right sides of the opening 14. Therefore, the batted ball flowing down the gaming section 7 is caused by the opening 1.
When the ball reaches 4, it is guided by one of the guide pieces and enters the inside, becoming a winning ball, so the winning probability of the hit ball increases.

The first profit game described above does not continue indefinitely, but only for the set time of the timer 55b.

This timer 55b controls the shift register 51b.
The operation starts with the MSB output and the set time (e.g. 15
When the time has elapsed (seconds), the AND gate 56b performs an AND operation with the Q output of the flip-flop 49b that has been set, and the output of the AND gate 5
6b returns the flip-flop 49b to its initial state, and at the same time, the low-level Q output is applied to the reset input of the shift register 51b having an inverted reset input via the OR gate 67a, and the shift register 51b is reset. All the electromagnets 25a, 17a, 17b, 25b are demagnetized.

Therefore, the first profit game lasts only for example, 15 seconds set by the timer 55b, and does not have a repeat function like the special game described above, and when it ends, returns to the initial state with the second output 45b. .

In addition, the structure of the code|symbol which added b to the number in the circuit of the 1st profit game is the same as the structure of the circuit in the previous special game.

On the other hand, if the ball hit by the player achieves the first condition in the gaming section, but the specific gaming state is not achieved in another game, and the determination circuit 44 issues the third output 45c, it becomes a second profit game.

This second profit game has even less profit status for the player than the first profit game, and
The circuit configuration of the profit game is as shown in the drawing.
The circuit configuration is almost the same as the profit game.

To explain the electrical processing mode of this second profit game, the third output 45c and the flip-flop 37a
The AND gate 46c performs an AND with the Q output of the
It is given to one input of c. This AND gate 48
Since the other input of the flip-flop c receives the Q output of the flip-flop 49c, the flip-flop 49c is set and the Q output becomes high level. The high level signal of this Q output is sent to one non-inverting input of a three-input AND gate 50c which also has one inverting input, and the inverting input is a shift register having a 4-bit parallel output terminal that receives the output of this gate 50c as a clock. Receives the most significant bit output of 51c, and since this output is at a low level,
Each time the output of the oscillator 52 enters the other non-inverting input
The AND gate 50c passes this, and therefore the shift register 51c sequentially changes the parallel bit output from "1" to high level from LSB to MSB.

As a result, the electromagnet 17a is first excited via the OR gate 53a and the driver 54b, and then
The electromagnet 17b is excited via the OR gate 53b and the driver 54c, and then
When the MSB output is set to "1", this output closes the AND gate 50c and the output of the oscillator 52 is transferred to the register 5.
1c, so both electromagnets 17a,
17b is continuously excited.

This state is the mode of the second profit game, and both the guide pieces 15a and 15b are positioned at the lower side of the opening 14 by the excitation of both the electromagnets 17a and 17b, and a part of the hit ball is moved to the opening by both the guide pieces 15a and 15b. 14 and becomes the winning ball.

Therefore, in the second profit game, the electromagnet 17
Guide pieces 15a, 15b are activated by excitation of a, 17b.
is positioned at the lower side of the opening 14 to receive the batted ball flowing down the gaming section, and continues for the time set by the timer 55c (for example, 5 seconds). The timer 55c is connected to the shift register 5 similarly to the timer 55b.
It operates with the MSB output of 1c, and when the time-up elapses after 5 seconds, the AND gate 5
6c, the flip-flop 49c is reset by the output of the AND gate 56c and returns to the initial state, and the low level Q output is given to the reset input of the shift register 51c via the OR gate 67b, and the output of the shift register 51c is reset. 51c is reset and both electromagnets 17a and 17b are demagnetized.

In this way, the second profit game continues for, for example, 5 seconds set by the timer 55c, and like the first profit game, there is no repeat function.

In addition, in the second profit game, the configuration of the symbol with a suffix "c" is the same as the circuit configuration in the special game.

In addition, in the circuits for the first profit game and the second profit game, OR gates 67a and 67b are provided in the reset signal lines to the shift registers 51b and 51c,
The reason why the other inputs of the OR gates 67a and 67b are connected to the reset signal line to the shift register 51a for the special game is that even when the circuit system is operating due to the first profit game or the second profit game, the special game is reset at the same time. , I first demagnetized all the electromagnets.

Next, a case will be described in which the probability of occurrence of a special game is electrically adjusted.

Now, assuming that the outputs of the three decimal counters 40a to 40c are not modified in any way, in terms of decimal numbers, the probability that all of these output numbers will be a single number, for example "7", is 10 ³ This is 1/1000, and the specific game state is achieved only 1 out of 1000 times in another game. 10 each in this case
Considering the state of the weighted bits of the forward counter,
The weight 8 is "0111".

However, the output of any one of the three counters (for example, the decimal counter 40a), for example, the LSB, that is, the output with a weight of 1, is pulled up to the power supply potential +Vcc and set to "1" as shown by the connection line 68a. If fixed, the value for which the remaining 8-4-2 bits are "011" is "6" (0110) in addition to the decimal number "7" (0111). That is, actually counter 4
Even if 0a outputs "6", it is output as "7", so if counter 40a outputs "7" or "6", it can be considered that it is outputting "7". Therefore, the probability that this counter 40a outputs "7" is greater than that of the other counters 40b and 40c.
It becomes one-fifth compared to one-tenth. Therefore, the probability that all the counters 40a to 40c are set to "7" is 1/5 x 1/10 x 1/10 = 1/500, which increases the probability that a special game will occur.

In exactly the same way, if the LSB of the two decimal counters 40a and 40b is pulled up to the power supply potential +Vcc using the connection line 68b and fixed to "1", the probability that "7" will appear in each counter is 1/5 x 1. /5×1/10=1/250, which is 1/250, and each counter 40a to 4
If the LSB of both 0c and 0c is pulled up by the connection line 68c, 1/5 x 1/5 x 1/5 = 1/125, and the specific game state will be achieved only once out of 125 times in another game.

Of course, this probability adjustment can be done on either bit output, or instead of pulling it up to supply potential, one of the bits can be pulled down to ground potential, i.e. fixed at binary ``0''. This can also be done by doing the following:

In the embodiment shown in the drawings, electrical control is performed using a circuit, but the invention is not limited to this, and control may be performed using a microcomputer or the like.

Further, the variable prize winning device 13 is not limited to the embodiment shown in the drawings, and can be converted into a first state disadvantageous to the player and a second state advantageous to the player, and can also be converted into an acceptance state. Any structure may be used as long as it has at least a continuation opening 28 through which a hit ball can win.

On the other hand, in the embodiment shown in the drawings, the specific game state is achieved by the result mode of another game, but the invention is not limited to this. The ball enters one of the following, or the ball passes through the special winning frame 10c,
The system may be established by being detected by any one of the detectors 10a' to 10b', or
In addition to this, the winning may be achieved by a ball hitting the continuation opening 28 of the variable winning device 13 and being detected by the special switch 31.

Also, a certain period of time set in the timer 55a (for example,
30 seconds), the variable winning device 13 is continuously changed to the second state advantageous to the player, but the variable winning device 13 may be changed to the second state intermittently. . The predetermined conditions for converting the variable winning device 13 to the second state advantageous to the player include not only time control using the timer 55a, but also limiting the number of winning balls in the variable winning device 13, or When the variable prize winning device 13 converts intermittently, the number of times of conversion may be limited and combinations may be made as appropriate.

Furthermore, in the embodiment shown in the drawings, the timer 55
After the time set in a has elapsed, the next special game is started on the condition that the continuation condition is achieved. However, the present invention is not limited to this. Even if the set time remains, the next special game may be started immediately.

On the other hand, the privilege condition is achieved when the ball that enters the variable winning device 13 enters the internal privilege winning hole 29, flows down the privilege channel 32, and is detected by the privilege switch 33 as a privilege condition determining means. However, the present invention is not limited to this, and the privilege condition may be any condition as long as it is achieved based on the batted ball fired into the gaming section 7 and is more difficult to achieve than the continuation condition. It may be provided in the gaming section 7 outside the variable prize winning device 13, and a separate game is started on the condition that it is detected by the bonus switch 33.
The result may be achieved depending on the mode, or the detection timing of the continuation condition detection means for detecting the hit ball that enters the continuation slot 28 of the variable winning device 13 and the conversion drive end timing of the conversion drive control means. The benefit condition detecting means may detect both timings so that the bonus condition is achieved based on the bonus condition.

In addition, the profit condition when the benefit condition is achieved is to clear the count of the N-ary counter 62,
Although the count is restarted, the present invention is not limited to this, and it is also possible to allow several special games to be played after the maximum number of continuations has ended, or the special game after the maximum number of continuations has been completed is not limited to this. Conditions different from the special game, such as changing the set time of the timer 55a, limiting the number of winning balls in the variable winning device 13, or intermittently converting the variable winning device 13, The number of conversions may be made variable.

[Effects of the Invention] As explained above, according to the present invention, by setting the continuation condition in the conversion control that puts the variable winning device into the second state advantageous to the player, the continuation condition is achieved by winning the winning ball. If this is not possible, the variable prize winning device will be placed in the first state that is disadvantageous to the player, so it will be full of thrill and tension along with the expectation of achieving the continuation condition, and conversely, as long as the continuation condition is achieved. Since the player can continue playing the game in the second state that is advantageous to the player, the player can enjoy and feel motivated to gradually expand the profits he or she can receive.

In addition, by limiting the maximum number of times that the game can be repeated, it is possible to prevent profits from being unevenly distributed to only a limited number of highly skilled players, thereby distributing profits fairly to the players. Not only is this possible, but it is also possible to maintain an appropriate balance of profits between players and game parlors.

Furthermore, by setting bonus conditions, players are given the chance to increase the maximum number of continuations, and if they are lucky enough to meet the bonus conditions, they can further expand the benefits they receive. Not only can it give an unprecedented sense of expectation, but the bonus conditions are made more difficult to achieve than the continuation conditions, so the profit balance between the players and the gaming parlors is not disrupted, and it is beneficial for the players. The sense of accomplishment is high, and the profits gained from doing so provide a sense of satisfaction.

In addition to this, instead of simply awarding prize balls based on the operation of the prize ball ejecting device, the player is given the benefit of increasing the maximum number of consecutive wins with the variable prize winning device, so even in bonus games. It is possible to provide the original enjoyment of a pachinko game in which the player can demonstrate his/her gaming skills and expand the profits that he or she can receive.
