As shown in FIG. 2, a ball discharge device 17 and a ball for guiding a ball flowing down by the ball discharge device 17 to a ball supply tray 15 are provided on a back mechanism board 16 disposed on the back side of the game board 3. A back mechanism such as a discharge gutter 18 is provided. In the present embodiment, the number of prize balls discharged is set to seven regardless of which prize hole the ball hits, ie, the prize area. In addition, ball discharge device 1
7 may have not only a function of discharging prize balls but also a function of discharging game balls lent out by inserting a prepaid card. Further, a setting operation section 19 and the like for setting the probability of the special symbol display device 6 and setting a base value are provided below the rear side of the front frame 2. Also, keys 20a and 20b are provided to prevent these settings from being changed during business hours and to prevent anyone other than a specific administrator from performing unauthorized operations.

The hitting ball firing device 11 may be of any type as long as it has a function of firing a game ball supplied to a firing position formed at the inclined lower end of the firing rail 21.
For example, a firing rod having a resilient portion at the distal end may be rotated by driving a motor or a rotary solenoid, or may be driven by driving a plunger solenoid to reciprocate the resilient portion at the distal end and fire.

The hit ball fired by the hit ball firing device 11 reaches the upper end portion of the game section 5 from the shooting rail 21 via the guide rail 4 and is provided for an actual game, but reaches the game section 5. It acts on the shooting sphere sensor 22 on the way. The shooting ball sensor 22 detects a disadvantage required for the game by the player and sends a disadvantage signal, and detects a hit ball fired by the hit ball firing device 11 and sends a signal to an electric control device 23 described later. Any structure may be used as long as it has the function of performing the following. For example, a photo sensor type detector, a non-contact type detector, or the like may be provided facing the firing rail 21, and the passing of a hit ball may be detected by the detector.

The hit ball shot by the hit ball firing device 11 does not necessarily enter the game section 5 and is provided for the game, and may return from the middle and foul. For this reason, a foul ball detector 25 is provided in the middle of a foul ball recovery path 24 which extends downward from the inclined upper end of the firing rail 21 and communicates with the lower plate 13, and when the shot ball becomes foul, the foul ball is detected. A foul ball is detected by the detector 25 and a foul signal is sent to the electric control device 23. In addition, the foul sphere detector 25 is
This is for correcting data sent as a disadvantage to the player by the shooting ball sensor 22. If a foul ball can be detected and a foul signal can be transmitted, the structure and the mounting position are not limited.

The first specific winning opening 8 provided in the game section 5
In the present embodiment, is usually for satisfying the starting condition of the symbol display device 10, and is constituted by a gate having a ball passage opening through which a hit ball can pass downward from above,
A detector (normal symbol start winning switch) 26 for detecting a passing ball and sending a signal to the electric control device 23 is provided as first specific winning signal generation means. Therefore, when the ball flowing down in the game section 5 wins the first specific winning opening 8, the detector 26 detects the ball and the electric control device 23 detects the ball.
The ball passes through the special winning opening 8 and flows down inside the game section 5 again. Therefore, no prize ball is ejected. In the present embodiment, the signal sent from the detector 26 of the specific winning opening 8 is a starting condition establishment signal (first specific winning signal) of the ordinary symbol display device 10 described later. The specific winning opening 8 may have any configuration as long as it can detect a hit ball by the detector 26 and transmit a signal, and is not limited to the structure and the mounting position of the detector 26, and captures the detected hit ball as a winning ball. In such a configuration, the prize ball may be discharged.

Normally, the symbol display device 10 converts and displays symbols (identification symbols) such as symbols and numerals at a speed that cannot be identified by the naked eye under the control of the electric control device 23, and displays the symbols when the conversion display is stopped. particular the stop display mode has been set in advance
If the display mode (prize mode) is set, a bonus is given to the player. The ordinary symbol display device 10 shown in the drawings
It is composed of a 7-segment display, and displays a high-speed conversion of the numbers "0" to "9" by a signal from the electric control device 23, and sets the number displayed beforehand when the variable display is stopped. If a certain number, for example, “7”, a prize mode is formed, and as a privilege, a condition for converting the first variable winning device 7 into a state advantageous to the player according to the value of the prize mode is established. That is, the ordinary symbol display device 10 in the present embodiment determines the formation of the operating condition of the first variable winning device 7 based on the first specific winning signal from the first specific winning signal generating means (detector 26). It functions as a part of the winning device operating condition forming means. In this embodiment, it is set so that the prize mode of “7” has the highest value, the prize mode of “5” has the next highest value, and the value of the prize mode of “3” has the lowest value. is there. Also, the ordinary symbol display device 1
0 indicates not only that the symbol is variably displayed, but also that a plurality of lamps are sequentially blinked and moved, and a blinking form is formed when the blinking movement is stopped at a predetermined lamp and continuously lit. .

The first variable winning device 7 functioning as a starting winning device is a normal variable winning device that can be converted into a first state disadvantageous to the player and a second state advantageous to the player. The first variable winning device 7 shown in FIG.
A pair of left and right movable members 29, 29 are axially mounted in an open top pocket frame 28 provided on the surface of the mounting board 27, and driven by an electric drive source such as a solenoid (not shown) provided on the back side of the mounting board 27. By reciprocating the movable members 29, 29, the movable members 29, 29 are almost upright, the upper end interval is narrow, and it is difficult to hit a ball, and the upper ends of the movable members 29, 29 are tilted outward. The configuration is such that the upper end interval is widened so that the state can be changed to the second state (FIG. 5) in which a hit ball can easily enter. Then, a detector 30 that detects a hit ball that has won the first variable winning device 7 and sends a signal to the electric control device 23.
Is provided facing the flow path in which the winning ball flows down. In the present embodiment, in addition to detecting the number of winning balls of the hit balls that have won the first variable winning device 7, the first variable winning device 7
, And the detector 30 functions as a second specific winning signal generating means (special symbol starting winning switch) for generating a second specific winning signal which is a starting condition of the special symbol display device 6.

Accordingly, when a hit ball is won while the first variable winning device 7 is in the first state or the second state, the detector 30 as a second specific winning signal generating means detects the winning ball and the electric control device. 23, a second specific winning signal is sent out, the hit ball that has won is processed as a winning ball, and a predetermined number (seven in this embodiment) of balls are set as prize balls in the ball supply tray 15 by operating the ball discharging device 17. Is discharged. As described above, when a hit ball is won in the first variable winning device 7, a predetermined number of prize balls are given, and a privilege is given based on the second specific winning signal from the detector 30. However, when the first variable winning device 7 is in the second state, the probability of winning a hit ball is higher than in the first state, and in this embodiment, the prize in the ordinary symbol display device 10 is used. Since the time during which the first variable winning device 7 is changed to the second state changes in accordance with the value of the mode, the number of prize balls discharged based on winning in the first variable winning device changes in accordance with the prize mode, As a result, the current base value approaches the reference base value.

For example, when the value of the prize mode on the ordinary symbol display device 10 is stopped and displayed at "7", the first variable prize apparatus 7 continues the second state for 6 seconds, which is an average prize mode. The second state is configured to be continued for 4 seconds in the case of “5”, and for 2 seconds in the case of stop display at the lowest value “3”. When the prize mode is formed by displaying “7”, “5” is displayed.
Since the second state continuation time of the first variable prize device 7 is longer than 6 seconds as compared with the prize mode by displaying “3” or “3”, the number of hit balls prize to the first variable prize device 7 also increases. Therefore, even if the prize mode is formed in the ordinary symbol display device 10 itself, in the case of “7”, the number of prize balls discharged increases, thereby increasing the current base value. Therefore, if the current base value is lower than the reference base value, "7"
Is controlled to increase the current base value.

When the prize mode is formed by displaying "5", the second state continuation time of the first variable prize device 7 is 4 seconds. The second state time of the single variable winning device 7 is short. Therefore, in the case of “5” as compared with the case of “7”, the number of winning hits to the first variable winning device 7 decreases, and the number of prize balls discharged also decreases in the case of “7”. . And "5"
The second state continuation time is based on the current base value as long as the number of shot balls continues to increase and the number of shot balls increases even if prize balls are discharged several times based on winning in the first variable winning device 7. The time that hardly changes the time is selected. Therefore, when the prize mode is formed when the current base value is substantially the same as the reference base value, the prize mode by “5” is formed to maintain the current base value.

When a prize mode is formed by displaying "3", the first
The second state duration time of the variable winning device 7 is 2 seconds,
Since the second state continuation time of the first variable prize device 7 is shorter than in the case of “7” or “5”, the number of prize balls discharged by prize to the first variable prize device 7 is naturally small. The second state continuation time of “3” is set as long as the number of effective fired balls increases even if the hit balls are continuously fired even if the prize balls are discharged based on the winning in the first variable winning device 7. It is the time when the current base value gradually decreases. Therefore, when the prize mode is formed when the current base value is higher than the reference base value, the prize mode of “3” is formed to reduce the current base value. Since the second state time of the first variable winning device 7 varies depending on the model, the experiment is repeated in advance, and the time required to increase the base value, the time required to maintain the base value, and the decrease of the base value are performed. Select and set the time that is sufficient.

In the present embodiment, a special game can be played by the special symbol display device 6 as a privilege of winning the first variable winning device 7, and when a prize mode is formed by the different game, the winning probability is reduced. Extremely high special games (special fluctuation prize winning device)
The second variable winning device 9 is opened according to a predetermined rule.
Conversion game machine) .

The special symbol display device 6 converts and displays symbols (identification symbols) such as symbols and numerals at a speed at which the symbols cannot be identified by the naked eye, and presets a stop display mode by combining symbols when the conversion display is stopped. If it is in a certain mode, a privilege is given to the player. The special symbol display device 6 shown in the drawing is a display 31a, 31b, which can display a number or the like vertically and horizontally by scrolling a number of LEDs vertically.
31c is attached to the substrate 32, and three are arranged in the case 33 side by side. When the special symbol display device 6 is activated by a signal from the electric control device 23, the three indicators 31a, 3
The numbers "0" to "9" are displayed at high speed on 1b and 31c, respectively, and after a predetermined time, the conversion display on each display 31 is sequentially stopped. And three display devices 31
The combination of the numbers displayed on a, 31b, and 31c is a prize, for example, “3, 3, 3”, “5, 5, 5”,
If it is "7, 7, 7", the right for special game is generated. As will be described later, the probability of the formation of the prize mode is configured in this embodiment so that the probability can be appropriately selected from several levels of probabilities and set in advance.

It should be noted that the special symbol display device 6 is not limited to the above-described configuration, but may have any configuration as long as a plurality of identification symbols can be converted and displayed at an indistinguishable speed.
For example, as shown in a special symbol display device 6 'shown in FIGS. 7 and 8, the drums 34a, 3a having a plurality of symbols on the outer peripheral surface.
4b and 34c may be rotated by driving a pulse motor.

In the special game, the second variable winning device 9 is changed from the first state, which is disadvantageous to the player, to the second, which is advantageous to the player.
The state is converted until the predetermined end condition is satisfied.

The second variable winning device 9 shown in FIG. 9 is a variable winning device called a so-called attacker.
5, a horizontally long ball entrance 36 is opened as a winning area, and a horizontally long door member 37 is rotatably mounted on the ball entrance 36, and a concave chamber whose front face communicates with the ball entrance 36 on the back side of the mounting substrate 35. 38, a continuous winning opening 39 and general winning openings 40, 40 are provided in the recessed chamber 38, and a solenoid (not shown) is provided on the back side of the mounting board 35 as an electric drive source. The door member 37 is opened and closed by driving to convert the state into a first state in which a hit ball is not received and a second state in which a hit ball is easily received. That is, when the solenoid is demagnetized, the door member 37 is urged by a spring or the like.
When the solenoid rises and closes the ball entrance 36 and does not accept a hit ball (first state disadvantageous to the player) and the solenoid is energized by a signal from the electric control device 23, the upper end of the door member 37 moves forward. The ball entrance 36 is opened by turning in the direction in which the ball is tilted, and the ball is converted into a second state (a state shown in FIG. 9) in which the ball can be easily received. Further, a counting detector 41 that detects all the balls that have won the second variable winning device 9 and sends a signal to the electric control device 23, and an electric control device that detects the ball that has won the continuous winning opening 39. 23 is provided with a continuation detector 42 for transmitting a continuation signal. The second variable winning device 9
The configuration is not limited to the so-called attacker type described above, and any configuration may be used as long as it can be converted into a first state disadvantageous to the player and a second state advantageous to the player. For example, the receiving state of a hit ball may be changed by rotating a pair of left and right movable members.

The special game is performed by changing the second variable winning device 9 from the first state disadvantageous to the player to the second state favorable to the player, and a predetermined time (for example, 28 seconds) elapses. Alternatively, the cycle until one of the conditions until a predetermined number (for example, 10) of hit balls is won is defined as one cycle, and the cycle is updated on condition that the hit ball wins the continuous winning opening 39 during this cycle. This cycle can be updated up to a predetermined number of times (for example, 16 times).

Next, the game will be described, and the electrical control unit 23 having a microcomputer structure for controlling the game will be described. The player operates the firing handle 1
When the hit ball launching device 11 is operated by operating the ball 2, the ball introduced from the ball supply tray 15 is fired one by one, supplied to the upper part in the game section 5, and provided for an actual game. When the hitting ball firing device 11 fires one ball after another (for example, 100 balls per minute), the firing ball sensor 22 detects one ball and sends a firing ball signal each time the electrical control device 23 effectively fires the ball. The ball is sent to the number-of-balls calculating means 51, and when the hit ball becomes foul, a foul-ball signal is sent to the effective number-of-launched-balls calculating means 51 each time the foul-ball sensor 25 detects a foul ball.

Upon receiving the launch sphere signal and the foul sphere signal, the effective launch sphere number calculating means 51 calculates the effective launch sphere number based on these signals, and sends the calculated value to the base value calculating means 52. The base value calculation means 52
To calculate the actual base value at the present time, that is, the current base value. Therefore, the base value comparison determination means 53
By comparing the calculated base value (current base value) with a preset reference base value, it can be determined whether or not the operation of the gaming machine 1 is currently as planned. The reference base value may be variably set by an external operation at the game store, as described later, while the value once stored is fixed.

When the hit ball shot into the game section 5 hits the obstacle nail and drops while changing the flowing direction, and when the hit ball passes through the first specific winning opening 8, a detector as a normal symbol start winning detecting switch is provided. 26 detects this hit ball and sends a first specific winning signal to the electric control device 23. When hit balls pass one after another in the special winning opening 8, a predetermined number may be stored in the electric control device 23, and the stored number may be visually displayed to the player.

When the electric control unit 23 receives the first specific winning signal, the ordinary symbol display control means 54 operates to activate the ordinary symbol display device 10 to start variable display, and the ordinary symbol random number generating means 55 Generates a random number, and determines whether or not the random number is a hit.
If the judgment result is out of order, it is sent to the ordinary symbol display control means 54, and if it is a hit, it is sent to the hit symbol selecting means 57.

When the ordinary symbol display control means 54 receives a signal indicating that it is out of the ordinary symbol hit determination means 56, when a predetermined time set in the ordinary symbol display control means 54 elapses, the ordinary symbol display control means 54 Is selected in advance, and the conversion display of the ordinary symbol display device 10 is stopped and displayed with the selected symbol. For example, "1", "2",
The display symbol is selected so as to stop at any one of "4", and the variable display is stopped at this symbol. In addition, even if the symbol design display device 10 is stopped at a symbol that has come off, there is no change in the subsequent game.

On the other hand, when the hit symbol selecting means 57 receives a signal indicating that a hit has occurred from the normal symbol hit determining means 56, the winning symbol is selected based on the determination result from the base value comparing / determining means 53. That is, in the present embodiment, when the current base value is lower than the reference base value, the hit symbol selecting means 57 selects a hit symbol of "7", and sends a signal to that effect to the opening time as the time control means. While sending to the control means 58,
It is sent to the ordinary electric accessory drive control means 59 and the ordinary symbol display control means 54. When the ordinary symbol display control means 54 receives the above signal from the hit symbol selection means 57, the variable display of the ordinary symbol display device 10 is stopped after a lapse of a predetermined time set in the ordinary symbol display control means 54, and "7" Is displayed,
The operating conditions of the first variable winning device 7 are formed. When the ordinary electric accessory drive control means 59 receives the above signal, the variable display of the ordinary symbol display device 10 is stopped, and then the solenoid of the first variable winning device 7 is excited and the hit ball is hit from the first state in which the hit ball is not accepted. Is converted to a second state that is easy to receive, and a signal is sent to the ordinary electric accessory opening display control means 60, which emits an ordinary electric accessory opening display 61 such as an LED. Display to the player. Opening time control means 58 is hit symbol design means 57
When the first variable winning device 7 receives the above signal from the control unit 5 for a predetermined time (6 seconds) corresponding to the value of the prize mode by "7", the first variable winning device 7 outputs a signal to continue the second state.
Send to 9. Therefore, the ordinary electric accessory drive control means 59
Excites the solenoid of the first variable winning device 7 until 6 seconds set by the opening time control means 58 elapse.

When the first variable winning device 7 is converted into the second state, the hit ball that has flowed down easily enters the first variable winning device 7. When the hit ball actually wins, the hit ball is converted into a second specific winning signal. Special symbol start winning detector 3 as generating means
0 is detected and a second specific winning signal is sent to the ordinary electric accessory drive control means 59, the base value calculation means 52 and the start storage control means 62 of the electric control device 23. Then, since the winning ball is processed as a winning ball, the ball discharging device 17 is operated to discharge a predetermined number of balls to the ball supply plate 15 as prize balls. When the prize ball is discharged, the base value at that time changes.
Base value calculating means 5 receiving the second specific winning signal from 0
2 calculates and calculates the number of ejected prize balls, and sends it to the base value comparison determination means 53. When the normal symbol display device is stopped and displayed at “7” to form a prize mode, the first variable prize device 7 continues the second state for 6 seconds, and the first variable prize device 7 successively receives a hit ball. It is possible to discharge a prize ball every time a prize is won. Therefore, the first variable winning device 7
If there is a prize ball discharge after winning one after another, the actual base value becomes higher in a shorter time than before. For this reason, in a state where the actual base value is lower than the reference base value, if the number of the normal symbol display device 10 is controlled to be a hit of “7”, repeated winnings and degrees to the first variable winning device 7 are repeated. Overlapping prize balls are discharged, resulting in an increase in the actual base value. Then, the opening time control means 58
After a lapse of the predetermined 6 seconds set by the above, the ordinary electric accessory drive control means 59 demagnetizes the solenoid of the first variable prize device 7 and moves the first variable prize device 7 from the second state in which hitting is easy to win. The hit ball is returned to the first state in which no prize is won.

When the current base value is substantially the same as the reference base value, the hit symbol selecting means 57 selects a hit symbol of "5" and sends a signal to that effect to the opening time control means 58. It is sent to the electric accessory drive control means 59 and the normal symbol display control means 54. Normal symbol display control means 54
Receives the signal from the hit symbol selection means 57, the variable display of the normal symbol display device 10 is stopped at "5" after a predetermined time set in the normal symbol display control means 54 has elapsed. When the ordinary electric accessory drive control means 59 receives the above signal, the variable display of the ordinary symbol display device 10 is stopped, and then the solenoid of the first variable winning device 7 is excited and the hit ball is hit from the first state in which the hit ball is not accepted. Is converted to a second state that is easy to receive, and a signal is sent to the ordinary electric accessory opening display control means 60, and the ordinary electric accessory opening display control means 6
0 emits an ordinary electric accessory opening indicator 61 such as an LED to visually display to the player. When the opening time control means 58 receives the above signal from the hit symbol selection means 57, the first variable winning device 7 continues the second state for a predetermined time (4 seconds) corresponding to the value of the prize mode by "5". Is sent to the ordinary electric accessory drive control means 59. Therefore, the ordinary electric accessory drive control means 59 excites the solenoid of the first variable winning device 7 until four seconds from the opening time control means 58 elapse.

When the first variable winning device 7 is converted to the second state, the hit ball that has flowed down easily enters the first variable winning device 7. When the hit ball actually wins, the hit ball is detected as a special symbol start winning detection. And the base value calculation means 52 of the electric control device 23.
Is transmitted to the start storage control means 62. Then, since the winning ball is processed as a winning ball, the ball discharging device 17 is operated to discharge a predetermined number of balls to the ball supply plate 15 as prize balls. When the prize ball is discharged, the base value at that time changes. Therefore, this base value is calculated by the base value calculation means 52 which has received the second specific prize signal from the special symbol starting prize detector 30. The number of balls is calculated and then sent to the base value comparison / determination means 53. When the normal symbol display device stops at "5" and forms a prize mode, the first
Since the variable winning device 7 continues the second state for only 4 seconds,
The first variable winning device 7 is capable of winning a plurality of hit balls, although less than in the case of "7", and discharges a prize ball every time a win is made. However, even during these winnings, hit balls are fired one after another, and the number of effective fired balls increases. Therefore, even if a hit ball wins in the first variable winning device 7 and a prize ball is ejected, the actual base value hardly changes compared to before. Therefore, in a state where the reference base value and the actual base value are almost the same, if the number of the normal symbol display device 10 is controlled to be a hit of “5”, the winning in the first variable winning device 7 and the prize ball Even if the discharge is performed, the actual base value hardly changes. Then, when the predetermined four seconds set by the opening time control means 58 elapse, the ordinary electric accessory drive control means 59 demagnetizes the solenoid of the first variable winning device 7, and the first variable winning device 7 is hit by a ball. It returns from the second state in which it is easy to win to the first state in which the hit ball does not win.

When the actual base value is higher than the set reference base value, the hit symbol selecting means 57 selects a hit symbol of "3" and sends a signal to that effect to the opening time control means 58. , And sent to the ordinary electric accessory drive control means 59 and the ordinary symbol display control means 54. When the ordinary symbol display control means 54 receives the above signal from the hit symbol selection means 57, the variable display of the ordinary symbol display device 10 stops at "3" after a predetermined time set in the ordinary symbol display control means 54 has elapsed. I do. When the ordinary electric accessory drive control means 59 receives the above signal, the variable display of the ordinary symbol display device 10 is stopped, and then the solenoid of the first variable winning device 7 is excited and the hit ball is hit from the first state in which the hit ball is not accepted. Is converted to a second state that is easy to receive, and a signal is sent to the ordinary electric accessory opening display control means 60, which emits the ordinary electric accessory opening display 61 and emits a signal. Is displayed on the screen. When the opening time control means 58 receives the signal from the hit symbol selection means 57, the first variable winning device 7 continues the second state for a predetermined time (2 seconds) corresponding to the value of the prize mode by "3". Is sent to the ordinary electric accessory drive control means 59. Therefore, the ordinary electric accessory drive control means 59 outputs the two
The solenoid of the first variable winning device 7 is excited until the second has elapsed.

When the first variable winning device 7 is converted to the second state, the hit ball that has flowed down easily enters the first variable winning device 7. When the hit ball actually wins, the hit ball is detected as a special symbol start winning detection. And the base value calculation means 52 of the electric control device 23.
Is transmitted to the start storage control means 62. Then, since the winning ball is processed as a winning ball, the ball discharging device 17 is operated to discharge a predetermined number of balls to the ball supply plate 15 as prize balls. When a prize ball is ejected, the base value at that time changes, and the base value is calculated by the base value calculation means 52 which has received the second specific prize signal from the special symbol starting prize detector 30. After calculating the number, it is calculated and sent to the base value comparison determination means 53. When the normal symbol display device is stopped and displayed at “3” to form a prize mode, the first variable prize device 7 keeps the second state for 2 seconds. A smaller number of hit balls can win, and if the player wins, the prize ball is discharged. However, even if the first variable prize device 7 converts to the second state for 2 seconds, the second state continuation time is much shorter than in the case described above, so the prize is not necessarily won. The number is also extremely small. Also, while the first variable winning device 7 is converting to the second state, hit balls are fired one after another, and the number of effective fired balls increases. Therefore,
Even if the first variable winning device 7 does not receive a hit ball, of course, even if the player wins and the prize ball is ejected, the actual base value hardly rises as compared to before.
It tends to fall. For this reason, when the actual base value is higher than the reference base value, the number of the normal symbol display device 10 is controlled to be a hit of “3”. When the predetermined two seconds set by the opening time control means 58 elapse, the ordinary electric accessory drive control means 59 demagnetizes the solenoid of the first variable winning device 7, and the first variable winning device 7 is hit by a ball. It returns from the second state in which it is easy to win to the first state in which the hit ball does not win.

As described above, the second state time of the first variable winning device 7 is indirectly controlled by directly controlling the hit of the symbol display device 10 based on the comparison result between the actual base value and the reference base value. In this case, the actual base value gradually approaches the reference base value.

That is, the above-mentioned ordinary drawing hit determination means 5
6, per symbol selection means 57, the opening-time control means 58, by Hiroshiden drive control means 59 cooperate, "normal symbol display
Based on the establishment of the starting condition for variably displaying the device,

Is determined, and after the normal symbol display device is variably displayed,
A stop display mode related to the determination is derived and stopped, and the stop
The stop display mode has become a predetermined specific display mode
In connection with the above, the normal variable winning device corresponds to the specific display mode
The required time is converted to the second state.
This ordinary symbol display device 10 functions as "skill control means".
The stop display mode of the second variable as a normal variable winning device
To the first specific display mode in which the conversion time of the dynamic prize device 9 to the second state is 2 seconds (first time), and to the second variable prize device 9

Cooperate with each other to act on the above-mentioned normal symbol game control means, so that the starting rate which can be corrected and controlled so that the winning rate of the effective launch sphere to the first variable winning device 7 becomes a predetermined predetermined winning rate. It functions as a winning rate correction control means.

[0044] Thus to, start winning factor correction control unit, when the winning rate to the first variation winning device 7 to the effective shot ball is lower than a predetermined winning rate defined as the base value, Prussian
The first variation winning device 7 to passing symbol game control means second
The second conversion time for converting to the state is set to the second time .
Instructs to derive a specific display mode and displays normal symbols
When the stop symbol of the device 10 is "7", and the winning rate of the effective launch ball to the first variable winning device 7 is higher than a predetermined winning rate determined as a base value, a normal symbol game is performed. > first specific display state conversion time for converting a first variation winning device 7 to the control unit to the second state so as to obtain first hour
It was instructed to derive the like, the normal symbol display device 10
By setting the stop symbol to “3” , the prize rate to the normal variable prize apparatus 7 is corrected so as to approach a predetermined prize rate. When the winning rate of the effective launch ball to the first variable winning device 7 is substantially equal to the predetermined winning rate determined as the base value, the conversion time can be maintained so that the winning rate can be maintained. (For example, the ordinary symbol display device 10
(4 seconds based on the stop symbol "5"), the start winning rate correction control means may include a function of instructing the control means to control the conversion time of the first variable winning device 7.

In this embodiment, the number of prize balls discharged by the prize in the first variable prize device 7 is used as a basis for calculating the base value. It is desirable to arrange or adjust the obstacle nail.

As described above, when the prize mode is formed by the ordinary symbol display device 10, the possibility of hitting the first variable prize device 7 with a hit ball increases, and when the prize is won, the special symbol start prize detector which detects the prize ball. 30 sends a second specific winning signal to the start storage control means 62. Even if the first variable winning device 7 returns to the first state, there is a possibility that the hit ball wins,
When a hit ball is won in the first variable winning device 7 in the state, the special symbol table start winning detector 3 is used in the same manner as the above-mentioned winning.
0 detects a winning ball and transmits a second specific winning signal.

When the start storage control unit 62 receives the second specific winning signal from the special symbol start winning detector 30, it stores the start signal and the start storage display control unit 6 based on this storage.
5, a special symbol display device start right signal is sent, and the start storage display control means 65 is controlled by a start storage display 66 comprising an LED or the like.
To cause the player to visually display the special symbol display device start right. Therefore, when a hit ball is successively won in the first variable winning device 7, the start storage control means 62 stores the second specific winning signal one after another, and the stored number is visually displayed on the start storage display 66. You.

When the start storage control means 62 receives and stores the second specific winning signal from the special symbol start winning detector 30, the special symbol display control means 67 based on this storage.
Is sent to the random number extracting means 68.

When the special symbol display control means 67 receives a signal from the start storage control means 62, the operation of the special symbol display device 6 is started based on this signal, and the three displays 31
Numbers are variably displayed on a, 31b and 31c.

When the random number extracting means 68 receives the signal from the start storage control means 62, the random number extracting means 68 extracts a random number from the random number table set by the set random number selecting means 69 and sends it to the big hit determination means 70. In the present embodiment, the probability of establishment of the prize mode in another game performed using the special symbol display device 6 can be set in advance to six stages, and another game is performed based on the set random number table. It is configured.

To set the probability of the special symbol display device 6, a key is inserted into a keyhole of a key 20a provided in the setting operation section 19. When the key is inserted, the key insertion detector 71 detects the key insertion and sends out an activation signal to the special symbol probability setting storage control means 72 and the probability setting display control means 73 to send the special symbol probability setting storage control. The means 72 is set to a state where it can effectively receive the signal from the special symbol probability setting switch 74, and the probability setting display control means 73 is operated to start the display on the special symbol probability setting display 75 consisting of a 7-segment display. .

When the administrator operates the specific symbol display device probability setting switch 74 to send a signal to the specific symbol probability setting storage control means 72, the specific symbol probability setting storage control means 72 receiving this signal selects the set random number. A signal is sent to the means 69 and a signal is sent to the probability setting display control means 73. Note that the specific symbol probability setting switch 74 may be turned on and off by rotating the key,
It may be constituted by a dial type switch provided separately from the key.

Upon receiving the signal from the special symbol probability setting storage control means 72, the set random number selecting means 69 receives a signal from the special symbol display device random numbers 1 to 6 which are stored in advance according to the probability in accordance with the signal. One random number for the symbol display device is selected. These random numbers for the special symbol display device are random number tables in which the probability of winning (forming a prize mode) is changed stepwise. For example, the random number 1 for the special symbol display device is 1/15.
0, random number 2 for special symbol display device is 1/200, random number 3 for special symbol display device is 1/220, random number 4 for special symbol display device is 1/250, random number 5 for special symbol display device is 1/3.
00, the random number 6 for the special symbol display device is adjusted to a probability of 1/350. Therefore, for example, when the dial-type specific symbol probability setting switch 74 is set to “1”, the setting random number selecting means 69 selects the special symbol display device random number 1 having a probability of 1/150, and sets the special symbol probability setting accordingly. "1" is displayed on the display 75, and the specific symbol probability setting switch 7
When 4 is set to "2", the set random number selecting means 69 selects the random number 2 for the special symbol display device having a probability of 1/200, and accordingly, "2" is displayed on the special symbol probability setting display 75. ,..., A specific symbol probability setting switch 74
By operating, it is possible to freely select any random number from the special symbol display device random numbers prepared in advance,
The type of the selected random number is visually displayed on the special symbol probability setting display 75. Then, when a key is pulled out after selecting and operating a random number having a desired probability (for example, a random number 2 for a special symbol display device having a probability of 1/200) in accordance with the business policy, the selected random number is fixed. Therefore, business can be performed on that day in this state.

After the setting, the random number extracting means 68 receives a signal from the starting storage control means 62, and thereby the random number for the special symbol display device having a probability of 1/200 selected by the set random number selecting means 69. 2, one random number is extracted and sent to the big hit determination means 70 to make a determination.

When the big hit determination means 70 determines that the pattern is "missing", that is, that no prize mode is formed, a signal is sent to the stop symbol selection means 76, and the stop symbol selection means 76 comes off the symbol generation means 77 (for example, a symbol). , "3, 1, 5"), and sends a signal to the special symbol display control means 67 so that the variable display stops at this symbol. The variable display is stopped at "3, 1, 5".

On the other hand, if the big hit determination means 70 determines that a "hit", that is, a prize mode is formed, a big hit signal is sent to the big hit control means 78 and a signal is sent to the stop symbol selecting means 76 to stop the big hit. The symbol selecting means 76 receives the winning symbol from the winning symbol generating means 79 (for example, “7, 7,
7 ") and sends a signal to the special symbol display control means 67 so that the variable display stops at this symbol, whereby the special symbol display control means 67 changes the variable display of the special symbol display device 6 to" 7, Stop at 7,7 ".

When the big hit control means 78 receives the big hit signal, it sends a signal to the base value calculating means 52 to temporarily stop the calculation of the base value until the special game ends. As a result, the number of effective firing balls and the number of prize balls discharged during the special game are invalidated, and the significance of calculating the base value can be maintained. During the special game, the base value calculation means 52 does not calculate the current base value, and stores a predetermined number of signals from the detector 26 even if a hit ball passes through the first specific winning opening 8. The variable display of the normal symbol display device 10 may be configured not to be started until the above-mentioned special game is over, or the base value is not calculated but the normal symbol display device 10
May be configured to operate even during a special game.

When the jackpot control unit 78 receives the jackpot signal, it sends a signal to the jackpot drive control unit 81. Based on this signal, the jackpot drive control unit 81 activates the solenoid of the second variable winning device 9. Exciting and changing from the first state in which the hit ball is not accepted to the second state in which the hit ball is easily accepted, starts the first cycle special game. Upon receiving the jackpot signal, the jackpot control means 78 visually displays the cycle number, for example, “1” on the cycle number display 82.

In the first cycle of the special game, when a game ball wins the second variable winning device 9, the counting detector 41 detects one of these winning balls, and the special winning opening drive control means 81 and the big hit. A signal is sent to the control means 78, and based on this signal, the big hit control means 78 counts the number of winning balls in the cycle and visually displays it on the winning number display 83. Until the number of winnings in the second variable winning device 9 in the first cycle reaches a predetermined number (for example, 10) or a predetermined time (for example, 28 seconds) set in a timer in the jackpot control means 78 elapses. If the hit ball does not win in the continuous winning opening 39, the jackpot control means 78 ends the special game based on either one of the end conditions being satisfied, but the hit ball is hit before these end conditions are satisfied. Wins the continuous winning opening 39, the continuous detector 42 detects a winning ball in the continuous winning opening 39, and the large winning opening drive control means 81
And a continuation signal to the jackpot control means 78, and the continuation display 4
3 indicates to the player that the continuation condition is satisfied. Note that when the end condition is satisfied and the special game is finished without hitting the continuous winning opening 39 with a hit ball, the big hit control means 78 sends a signal to the base value calculation means 52 to restart the calculation of the base value, and Return to the playing state.

On the other hand, when the continuation condition is satisfied by the hitting of the ball into the continuous winning opening 39, the special winning opening drive control means 81 demagnetizes the solenoid of the second variable winning device 9 to return to the first state, and returns to the first state. After the wait time elapses, the solenoid of the second variable winning device 9 is again excited to convert to the second state. The big hit control means 78 returns the winning number display 83 to zero and updates the display of the cycle number display 82 to, for example, visually display "2".

In this way, the cycle is updated and the special game is continued by the hit ball winning the continuous winning opening 39, and the cycle is updated a predetermined number of times (for example, 16 times).
), The special game ends when either of the winning number reaches a predetermined number or a predetermined time elapses in the final cycle. When the special game is over, the base value calculation means 52 starts operating in response to a signal from the big hit control means 78 and returns to the normal game state, similarly to the case where the special game is over in the middle cycle.

As described above, in this embodiment, a base value which is a reference is set in advance, a base value in an actual game is calculated, and both base values are compared. When the base value in the game is low, when the normal symbol display device 10 wins the game, the second state of the first variable winning device 7 is set to a long prize mode, and the winning probability is long. The number of award ball discharges is increased by increasing the time, and control is performed so that the actual base value increases and approaches the reference base value. On the other hand, when the base value in the actual game is higher than the reference base value, the winning in the prize mode in which the second state of the first variable winning device 7 is short in a short time when the game is hit in the game of the ordinary symbol display device 10. Thereby, the increase in the number of winnings to the first variable winning device 7 is suppressed and the number of prize balls discharged is suppressed, whereby the actual base value is controlled so as to gradually decrease and approach the reference base value.
Also, when the reference base value and the actual current base value are almost the same, the first variable winning device 7 converts to the second state when a hit in a game of the ordinary symbol display device 10 and the hit ball is hit. The prize is won in a prize mode of a predetermined time that the base value does not change as much as possible even if a prize is won. Therefore, the base value obtained as an actual sales result approaches the base value set in advance without adjusting the obstacle nail (especially a nail that normally determines the winning probability of the first variable prize device 7), and the sales of the sales are reduced. Stabilization can be achieved. And since the prize form formation probability of the special symbol display device 6 can be set to a desired probability, the personality of each gaming machine 1 can be created by this setting,
The adjustment of the payout rate and the division number can be adjusted by this.

In the above-described embodiment, the base value serving as a reference remains fixed, and a desired base value cannot be set.
A desired value may be freely set according to the business policy for each case, or a base value prepared in stages may be selected and set. For example, as shown in FIG. 10, a reference base value variable setting means 85 having a base value serving as a reference in advance is provided, and the base value is set by operating a key inserted into a keyhole of the key 20 b provided in the setting operation unit 19. The switch 86 may be operated to select and set from base values prepared in advance in the reference base value variable setting means 85.

When the administrator operates the base value setting switch 86 connected to the key to send a signal to the reference base value variable setting means 85, the base value changes from the base values 1 to 6 stored in advance according to the signal. Selected one of the base values. For example, the base value 1 is “3”
5 ", base value 2 is" 45 ", base value 3 is" 50 ",
The base value 4 is "55", the base value 5 is "60", and the base value 6 is "70". Therefore, for example, when the display of the base value setting display 87 is adjusted to “1” by the base value setting switch 86, the reference base value 1 of “35” is selected, and “3” is displayed on the base value setting display 87. By selecting the reference base value 3 of "50", an arbitrary base value can be selected from the reference base values prepared in advance by operating the base value setting switch 86. , The selected base value is sent to the reference base value comparison determination means 53. Therefore, the base value comparison determination means 53 compares this reference base value with the current base value in the actual game.

In the gaming machine 1 described above, the combination of the reference base value selected by the reference base value variable setting means 85 and the special symbol display device random number selected by the probability setting random number selection means 69 is 6 × 6. = 36 combinations, and this combination can be appropriately selected. In this case, when a random number with a high probability is selected as the random number for the special symbol display device (for example, a random number 1 for the special symbol display device with a probability of 1/150), the probability that the right to the special game is generated increases, and the number of prize balls discharged Significantly increases in a short period of time, and the payout rate (fraction) increases, in other words, the profit obtained by the player in a short time sharply increases, and the profit obtained by the game store rapidly decreases. If a random number with a low probability is selected as the random number for the special symbol display device (for example, a random number 6 for the special symbol display device with a probability of 1/350), the probability that the right to the special game is generated becomes extremely low, and the prize is reduced. The number of balls ejected significantly increases within a short time, and the payout rate (fraction) hardly increases sharply. In other words, the profit obtained by the player in a short time sharply increases, and the game store side Profits rapidly decrease It will not become almost the state, such as Kunar. Also, if a high base value (for example, base value “70”) is selected as the reference base value, 70 prize balls will be discharged if 100 balls are fired on average, even if no special game is performed. Since the game can be played at a ratio, a state in which the game can be continued for a relatively long time (a state in which the ball has good mochi) is achieved, and a low base value (for example, the base value “35”) is used as the reference base value. ), The game can be played at a rate of 35 prize balls being discharged if an average of 100 balls are fired, so that the game is completed in a relatively short time (the ball stretches out). Bad state).
Therefore, it is necessary to select the special symbol display device random number and the reference base value of each gaming machine 1 according to the business policy.

For example, when a newly opened store is opened, the base value is increased to improve the ball mochi, and the probability of the random number for the special symbol display device is increased so that the right to the special game is easily generated. In the case of setting based on a business policy that allows a game to be played over a long period of time, the reference base value is increased to lower or set the probability of the random number for the special symbol display device to a medium level, and the game can be played in a short time. In order to make it a gaming machine, set the reference base value low and set the probability of the special symbol display device random number high, and use up the gaming balls in a short time and aim for one-sided profit acquisition on the amusement store side To do so, the reference base value is set low and the probability of the special symbol display device random number is set low.

As described above, the random number for the special symbol display device and the reference base value of each gaming machine 1 may be set by a separate operation according to the business policy, but a plurality of combinations (business mode) may be set in advance. A configuration may be made so that when this business mode is selected by an external operation of a business mode selection switch (not shown), a random number for the special symbol display device and a reference base value can be automatically set.

For example, the random number 1 for the special symbol display device (probability 1/15)
0) and the reference base value 6 of “70”, the “mode 2”, also known as “play mode 1”, has a special symbol display device random number 5 (probability 1/300) and the reference base value 5 of “6”.
In combination with “0”, a random number for special symbol display device 4 (probability 1/250)
The combination of "55" of the reference base value 4 and the "game 4", which is another name of the "mode 4", is a random number 1 for the special symbol display device (probability 1/150) and "35" of the reference base value 1 The combination of the random number 2 for special symbol display device (probability 1/200) and the reference base value 2 of “45” is referred to as “mode 5”. In the "collection mode", a combination of the special symbol display device random number 6 (probability 1/350) and the reference base value 1 of "35" is set in advance.

When the business mode setting switch is operated, any one of the business modes "mode 1" to "mode 6" can be selected by a signal from the business mode setting switch. When one business mode (for example, “mode 2”) is selected in this way, a signal indicating the business mode is sent to the probability setting random number selection means 69 and the reference base value variable setting means 85.

When the probability setting random number selecting means 69 receives the mode setting signal, it selects a special symbol display device random number corresponding to the mode setting signal. For example, when "mode 2" is set, the special symbol display device random number 5 (probability 1/300) is selected.

When the reference base value variable setting means 85 receives a mode setting signal, it selects a reference base value corresponding to the signal. For example, when “mode 2” is set, “60” of the reference base value 5 is selected, and this reference base value is sent to the base value comparison determination means 53.

Therefore, when business is started in this business mode, the base value comparison / judgment means 53 sets the base value “6”.
The open time of the first variable prize device 7 is adjusted by performing a comparison determination with the current base value based on "0", and the first variable prize device 7 is awarded and a second specific prize signal is sent to send a special symbol. The result of the variable display on the display device 6 is controlled by the special symbol display device random number 5 having a probability of 1/300.

In each of the above-described embodiments, when the current base value is calculated by the base value calculating means 52, the first variable winning signal is detected based on the second specific winning signal detected by the first variable winning device 7. The ratio between the number of prize balls ejected based on winning in the device 7 and the number of effective launch balls from the effective launch ball number calculation means 51 has been calculated. However, the calculation of the base value in the present invention is not limited to this. The base value may be calculated based on the number of prize balls discharged in the normal game state and the number of effective fired balls excluding the number of prize balls discharged and the number of effective fired balls in the special game state in which the winning probability is significantly increased. For example,
As shown in FIG. 4, a ball detector 91 is also provided in each of the general winning ports 63 where a prize ball is discharged when a hit ball is won, or a winning ball that has flown in these winning ports 63 flows down. A ball detector 91 may be provided in the flow path, and the number of prize balls discharged in the normal game state may be calculated based on signals from the detectors 91..., And the base value may be calculated using the prize ball discharge number. . As described above, when the base value is calculated by taking into account the number of prize balls discharged by winning other than the first variable winning device 7, the original base value can be calculated more accurately. However, most of the prizes in the first variable prize device 7 and the gaming machine 1 in which obstacle nails are arranged so that prizes in other prize ports 63 are extremely small, the first variable prize device. 7 can be achieved even if the winning of the prize 7 is detected and the base value is calculated using the number of prize balls discharged based on the winning of the first variable prize device 7.

In the case of the gaming machine 1 in which the number of prize balls discharged for one prize is the same, the number of prize balls × n
(For example, n = 13), the prize ball discharge number is calculated. When the winning value differs depending on the winning opening and the prize ball discharge number also differs, the respective prize ball discharge numbers are calculated and added.
If the ball discharge device 17 is provided with a discharged ball detector (not shown), the number of prize balls actually discharged is detected based on a signal from the discharged ball detector, and based on the detected signal. May be used to calculate the current base value.

In calculating the base value, the number of effective firing balls is used as the denominator (the number that is the base of the base value) as a disadvantageous number for the player required for the game. The number is not limited to this, and the number is not limited to that the number of effective shots is detected by the shot ball sensor 22 and the foul ball sensor 25 and the effective shot number is calculated based on signals from these sensors 22 and 25. For example, an out ball detector that detects one out ball (a ball that did not win any prize device) discharged from the gaming machine 1 and a safe ball (a ball that has won any prize device) And a safe sphere detector for detecting the number of effective spheres may be calculated based on the sum of signals from both detectors as the recovered sphere detecting means.

In the embodiment described so far, the condition that the variable display of the special symbol display device 6 is stopped and the prize mode is formed is set as the condition for generating the right of the special game. However, the present invention is limited to this game content. It is not something to be done. For example, when a hit ball wins a specific start winning opening, the variable winning device 9 changes from a first state in which the hit ball is not received for a relatively short predetermined time or a predetermined number of times to a second state in which the hit ball is easily received, and this second state.
In the state, the hitting ball wins a specific right generation winning opening, thereby generating a special game right. In the special game, the variable winning device easily receives a hitting ball from the first state in which the hitting ball is not received for a predetermined time or a predetermined number of times. The game may be converted to the second state, and the special game may be continued on condition that the hit ball wins the continuous winning opening 39 (which may be the same as the right generating winning opening) in the second state. In this case, a variable winning device is used for the starting winning opening, and a normal symbol display device for performing variable display by hitting or passing the specific winning opening and the specific winning opening is provided in the specific winning opening, and a reference base value and an actual symbol display device are provided. By comparing the base value of the game with the current base value and controlling the appearance of the ordinary symbol display device based on the comparison result, the variable winning device is converted from the first state in which the hit ball is difficult to enter to the second state in which the hit ball is easy to enter. The current base value may be controlled, or the duration and the number of conversions of the second state of the variable winning device as a starting point may be forcibly controlled without providing a normal symbol display device.

Further , the present invention is not limited to the one in which the second variable winning device is directly converted from the first state disadvantageous to the player to the second state advantageous to the player due to the right of the special game being generated and the special game is started. Instead, the second variable winning device may be changed from the first state to the second state on condition that a hit ball wins in the opening opening where the opening condition is established after the right for the special game is generated.

In the present invention, the setting operation section 19 for setting the probability of the special symbol display device 6 and setting the reference base value is not limited to the above-described embodiment.

Configured as a normal variable winning device that can be converted to
When the starting condition is satisfied when the game ball passes through the specific winning area
The control of the normal symbol game control means is started is variably displayed in normal symbol display device, when the variable display stop results aspects in normal symbol display device is a particular display mode, Normal
By the symbol game control means, the normal variable winning device is the first
It is assumed that the state is converted from the state to the second state. At this time, when the winning rate of the game ball provided for the game to the normal variable winning apparatus is lower than a predetermined winning rate,
The longer the second time relatively time conversion time when converting to the normal symbol game control means the ordinary variation winning device to the second state by starting winning factor correction control means
In the case where the instruction to derive the second specific display mode is given while the winning rate of the game ball provided for the game to the normal variable winning apparatus is higher than a predetermined winning rate, From the start winning rate correction control means, the normal symbol play
Short the first hour of the relatively time conversion time when it relative skill control means for converting the common variation winning device to the second state
Since it is assumed that the instruction to derive the first specific display mode is given, the prize rate to the normal variable prize apparatus approaches a predetermined prize rate. Based on the game ball prize winning in the normal variable prize winning device, the rate at which the variable display in the special symbol display device is started also approaches a constant value, the stop result mode of the variable display becomes the special display mode, and the special variable prize device is closed. Is also converted to an open state based on a predetermined rule.

Therefore, unlike the conventional game machine, the fine adjustment of the obstacle nail which requires a highly skilled technique can be performed without making a fine adjustment.
A gaming machine that can provide a player with an opportunity to obtain profits equally and can enjoy a game regardless of the skill of the player.
