[0006]

Embodiments of the present invention will be described below with reference to the drawings. First, the configuration of the gaming board 1 of the pachinko machine according to the embodiment will be described with reference to FIG. In the figure, a special winning device 4 is arranged substantially at the center of a game area 3 surrounded by a guide rail 2 of a game board 1.
The special prize winning device 4 has a plurality of passing areas 5, 6 a, 6 b including a special device operating area 5, turns a hit ball received from above using a spiral disk, and passes any one of the passing balls during the turning. It is to be dropped on the areas 5, 6a, 6b. The left and right passing areas 6a and 6b are configured as a winning passing area in which a predetermined number (for example, 15) of prize balls are discharged by dropping a hit ball. The special device operating area 5 in the center is guided downward as it is when the hit ball falls, and the special winning opening 7 arranged below the special winning device 5 is made to win. When a hit ball is won in the special winning opening 7, a predetermined number of prize balls are discharged in the same manner as described above, and the special winning ball detection switch 24 (see FIG. 9) built in the special winning opening 7 is turned on. The ON signal of the special winning ball detection switch 24 is used as a signal for detecting occurrence and disappearance of the right generation state. In the illustrated embodiment, only the hit ball guided by the electric winning device 16 described later is guided to the special winning device 4.

Below the special winning device 4, a variable winning device 8 is arranged. This variable winning device 8
It has an attacker opening / closing plate 9 driven to be opened and closed by an attacker solenoid 29 (see FIG. 9), and receives a hit ball falling in the game area 3 with the attacker opening / closing plate 9 opened. However, the opening of the attacker opening / closing plate 9 is executed based on the fact that the right generation state is continued and a hit ball is won in the starting winning opening 11 described later, and one opening is performed by a predetermined number (for example, Until ten winning balls are generated, or for a certain period of time (for example, 9.7)
Seconds) has elapsed. In order to count the above-mentioned predetermined number, the variable winning device 8 is provided with a winning ball number detecting switch 26 (see FIG. 9) and detects the number of winning balls detected by the winning ball number detecting switch 26. A winning number indicator 10 is built in for displaying.

[0008] Below the variable winning device 8, there is a starting winning opening 1
1 is provided. The start winning opening 11 opens the attacker opening / closing plate 9 based on the fact that the right generation state is continued as described above and the hit ball wins. Board 9
Therefore, when the attacker opening / closing plate 9 is open, the hit ball is unlikely to win the starting winning opening 11. The starting winning opening 11 is provided with a starting winning ball detection switch 25 (see FIG. 9) for detecting a winning of a hit ball. Furthermore, during the right generation state, the starting winning opening 1
The number of balls that have won 1 is displayed on a start winning number display 17 provided on one side (the right side in the figure) of the special winning device 4. The start winning number display 17 indicates the number equal to the number of times the attacker opening / closing plate 9 is opened in many cases. When the numerical value displayed on the start winning number display 17 becomes 16, the right generation state ends. Note that the number of prize balls discharged by hitting the starting winning opening 11 with a hit ball is set to a smaller number (for example, 7) than the number of prize balls discharged by the other winning openings.

[0009] Gate winning ports 12a and 12b are arranged substantially at the center and left and right of the game area 3, respectively. The gate winning ports 12a, 12b are not configured to discharge prize balls merely because a hit ball falling in the game area 3 passes therethrough, but the gate winning ports 12a, 12b.
This is expressed as a winning opening in the sense that the variable display of the symbol display device 13 provided on one side (the left side in the drawing) of the special winning device 4 is controlled by the passing of the hit ball through b. Of course, in this case, a winning opening from which a prize ball is discharged may be used. The gate winning ports 12a and 12b are provided with a gate winning ball detection switch 23 (see FIG. 9), and the symbol display device 13 performs variable display based on the detection signal.

The symbol display device 13 includes a plurality (two in the illustrated embodiment) of symbol indicators 14a and 14b (comprising 7-segment LEDs) and a gate winning memory display 15. I have. Symbol display 14a, 14b
Starts a fluctuating display based on the fact that a hit ball has been won in the gate winning openings 12a and 12b, and after a predetermined time (for example, 6 seconds) elapses, the left symbol display 14a stops, and then a slight time delay occurs. The right symbol display 14b is controlled to stop. Further, as the symbols displayed on the left symbol display 14a, for example, ten types of numeric symbols from 0 to 9 are variably displayed, and the right symbol display 1 is displayed.
The symbols displayed in 4b are, for example, 0-9, A, C,
Nineteen kinds of numbers and alphabetic symbols from E, F, H, J, L, P and U are displayed in a variable manner. And
When the combination of the symbols when both of the symbol indicators 14a, 14b are stopped is a combination of "3, 3" or "7, 7", it is determined that a hit has occurred, and the electric winning device 16 described later is opened and driven. It has become. Also, symbol display 1
4a and 14b use a two-color light emitting segment LED, and when a variable display is performed with a low probability described later, for example,
In the case of performing a variable display in red and a variable display with a high probability, for example, display control is performed so as to perform variable display in green. In this way, the player can immediately know at what probability the symbol display device 13 is variably displaying.

Further, the gate prize storage display 15 provided in the symbol display device 13 is provided with the gate prize opening 12a, 1
This informs that up to four hit balls that have passed through 2b have been stored. Even if the hit balls pass through the gate winning openings 12a and 12b with all four of the gate winning storage indicators 15 lit, it does not matter. Treated as invalid.

By the way, the symbol indicators 14a, 14b
When the combination at the time of stop becomes a winning symbol combination, the electric winning device 16 arranged above the special winning device 4 is opened for a predetermined time (for example, 6 seconds). The illustrated electric winning device 16 is a so-called tulip-type winning device, and includes a tulip solenoid 28 (see FIG. 9).
Is driven to open. Then
When the tulip solenoid 28 is excited and the electric winning device 16 is opened, the hit ball falling in the game area 3 is easily accepted, and the hit ball received by the electric winning device 16 is guided to the special winning device 4, and It falls into any of the above-mentioned passage areas 5, 6a and 6b. It should be noted that when one hit ball is won in the electric winning device 16, the tulip solenoid 28 is turned off and closed even before a certain time has elapsed. Further, in the illustrated electric winning device 16, an obstacle nail is provided so that a hit ball does not win at all when the electric winning device 16 is closed, but the electric winning device 16 is closed. At any time, a hit ball may be won.

Further, in addition to the above-described configuration, a plurality of winning ports 18, 19a, 19b, 2
0a, 20b, operation lamps 21a, 21b, and out port 2
2 are provided. Of these, the operation lamps 21a, 21
b mainly informs that the right is in the state of occurrence of the right, but the lamp display and the lamp group (not shown) that inform that the symbol display device 13 and the variable winning device 8 are being driven have respective winnings. The device and the winning ports 19a, 19
b, 20a, 20b, etc.

The configuration of a control device for controlling the operations of the symbol display device 13, the special winning device 4, the variable winning device 8 and the like described above will be described with reference to FIG. FIG. 9 is a block diagram showing an electrical configuration of the control device. The control device uses a microcomputer 30. An external ROM 31 and an external RAM 34 are connected to the microcomputer 30. The ROM 31 has an outlier numerical value table 32 for determining numerical values to be displayed on the symbol displays 14a and 14b in the off mode shown in FIG. 7, and a symbol display 14a and 14b in the hit mode shown in FIG.

Has a memory for the number of reserved winning balls of the gate winning ports 12a and 12b + 1. The numerical value for mode determination for each retained winning prize ball is determined at the time of winning (passing), and the numerical value is stored in each determination memory 38. As described later, the maximum value of the mode determination counter 35 is changed to change the occurrence probability of the hit mode.

Start winning prize ball detecting switch 25 for detecting a ball, winning prize ball detecting switch 2 for detecting a winning ball on the attacker opening / closing plate 9
6 and a tulip detection switch 27 for detecting a winning ball in the electric winning device 16 are connected to the microcomputer 30 via a waveform shaping circuit 39 composed of a flip-flop for preventing chattering.

The clock generation circuit 41 outputs an external interrupt signal via the frequency divider 40 to the IN of the microcomputer 30.
Output to T terminal. Then, the microcomputer 30 executes the main program shown in FIGS. 1 to 4 in synchronization with the external interrupt signal. The timing signal output from the timing signal generation circuit 42 is input to the RST1 terminal of the microcomputer 30, and the numerical value generation program shown in FIG. 6 is started in synchronization with the timing signal. The reset signal output from the reset signal generation circuit 43 by the ON operation of the power supply circuit 44 is input to the RST2 terminal of the microcomputer 30, and the reset signal activates the initial program shown in FIG.

A display drive circuit 45, a display selection circuit 46, and a driver 47 are connected to each output port of the microcomputer 30. The display drive circuit 45 and the display selection circuit 46 include the symbol displays 14a and 14 described above.
b, gate winning memory display 15, winning number display 10,
The start winning number display 17 is connected. These displays are dynamically driven by outputting selected data and display data from the microcomputer 30 at regular intervals. That is, each display unit is selected by the display selection circuit 46 and displayed according to the output signal of the display drive circuit 45 at that time. The driver 47 is provided with a tulip solenoid 28, an attacker solenoid 29, and an operation lamp 21 in accordance with a signal from the microcomputer 30.
a, 21b, and a lamp display and a lamp group (not shown) are driven and controlled.

Next, the operation controlled by the above-described control device will be described with reference to a flowchart showing a processing procedure of the microcomputer 30. (1) Initial setting at power-on When the power circuit 44 is turned on, power is supplied to the microcomputer 30 and the reset signal generating circuit 43
Outputs a reset signal to the RST2 terminal. Then
Microcomputer 30 (hereinafter referred to as CPU 30)
Executes the processing shown in FIG. That is, the symbol display 14
The two-digit numerical registers X1 and X2 displayed on a and 14b are set to the initial values (1, 5). In addition, gate winning opening 12
The gate winning counter C for counting the number of reserved balls awarded to the a and 12b is set to “0”, and the starting winning ball counter D for counting the number of winning balls to the starting winning opening 11.
To “0”, a winning ball counter E for counting the number of balls winning the attacker opening / closing plate 9 to “0”, a tulip winning counter B for detecting a ball winning to the electric winning device 16 to “0”, An opening number counter G for counting the number of times the attacker opening / closing plate 9 is opened is initialized to "0", and an operation number counter L for counting the number of operating times of the special device is initialized to "0". Also, status registers F, which store the control status,
H is set to "0" and timers T1, T2, T3 and T4 are set to "0".
Initialize to. Then, the numerical value I of the mode determination counter 35 is set to the initial value “1”, and the outlier numerical value table 3
The address J of No. 2 and the address K of the hit numerical value table 33 are each set to the initial value “1”. Although not shown, the probability increase flag and the right generation flag are reset at the time of the initial setting, and the green flag is also reset.

(2) Step of the mode determination counter and rotation of the numerical value table The numerical value generating program shown in FIG. 6 is started in synchronization with the timing signal input from the RST1 terminal. That is, it is determined in step 300 whether or not the probability increase flag is set. If not, Imax = 190 is set in step 302 as the final value of the numerical value incremented by the mode determination counter 35. If it is set, as the final value of the numerical value incremented by the mode determination counter 35, Imax =
19 is set. Then, in the next step 306, it is determined whether or not the value of the numerical value I of the mode determination counter 35 is equal to or greater than the final value set in step 302 or 304. If not, in step 308, the mode determination counter 35 is determined. Is incremented by one. If it is determined in step 306 that the numerical value I of the mode determination counter 35 is equal to or greater than the final value, the process proceeds to step 310 and the numerical value I of the mode determination counter 35 is set to the initial value of 1. In this way, the mode determination counter 35 generates a mode determination numerical value that is sequentially incremented in the range from the initial value 1 to the final value at an arbitrary time after the power is turned on. The generation speed of the numerical value at this time is determined by the timing signal output from the timing signal generation circuit 42.

Similarly, in step 312, the numerical value stored at the address J is read out from the numerical value table 32 for display in the deviating mode, and the numerical value is stored in each of the two digits of the deviating numerical value memory 37. It is memorized. Then, in the next step 314, it is determined whether or not the value of the address J is out of range and the final value of the address in the numerical value table 32. If not, the address J is incremented by 1 in step 316. If it is determined in step 314 that the value of the address J is the final value, the process proceeds to step 318, where the value of the address J is set to 1 as the initial value. Similarly, in steps 320 to 326, the numerical value stored in the address K of the hit numerical table 33 for display in the hit mode is stored in the hit numerical memory 37 as the hit mode display numerical value, and the address K is updated. When the value exceeds the final address of the hit numerical value table 33, the process of setting the initial value 1 is performed. In this way, every time a timing signal is input, the numerical value for display in the out-of-off mode is stored in the out-of-value memory 36, and
The display numerical value in the hit mode is stored. Each memory may store the address of the table so that the numerical value of the table at that address is read at the time of display.

(3) Main Program After the initial setting, each time an external interrupt signal output from the frequency divider 40 is input, the CPU 30 executes the main program shown in FIGS. In FIG. 1, the timer is updated in step 100, and the state signals S1, S2, S3, S4, and S5 of the switch group are read in step 102. These status signals are configured by negative logic, and when the signal is at a low level, the switch is in the ON state, indicating that a winning ball has been detected.

When the falling of the gate winning signal S1 is detected in step 104, step 106
It is determined whether or not the number of pending winning balls is smaller than four. Only when the number is smaller, the gate winning counter C is determined in step 108.
Is updated by 1 and the value of the mode determination counter 35 at that time is stored in the determination memory M (c) 38 at step 110. That is, when there is no pending winning ball, the gate winning opening 12
When a prize is detected in a or 12b, the gate prize counter C becomes 1, and the value of the mode determination counter 35 at that time is stored in the determination memory M (1). When the gate winning counter C is 1 or more, the gate winning port 12 is further increased.
When the player wins a or 12b, the winning ball becomes a reserved winning ball, and the gate winning counter C is incremented by one. Then, the value of the mode determination counter 35 at the time of winning is stored in the determination memory M (c) corresponding to the held winning ball. In this way, when the winning in the gate winning openings 12a and 12b is achieved, the numerical value for determining the winning mode is determined.

In step 112, a special winning signal S2
Is detected, it is determined in step 114 whether or not the right generation flag has been set. If not, the right generation flag is set in step 116. As a result, a right is generated. Then, when the right is generated, step 11 is executed.
If it is determined in step 8 that the probability increase flag is set, the probability increase flag is reset in step 120, and the green flag is reset in order to indicate that the symbol displays 14a and 14b are to be displayed with a low probability. This allows
The symbol display displayed on the symbol indicators 14a and 14b is displayed in red, thereby informing the player that the probability that the symbol is displayed is low. Then, thereafter, in step 122, the operation number counter L is incremented by one. On the other hand, when it is determined in step 114 that the right occurrence flag has already been set, the special winning signal S2 is treated as a signal for extinguishing the right occurrence state, and the process proceeds to step 132 described later.

In FIG. 2, when the falling of the start winning signal S3 is detected at step 124, it is determined at step 126 whether or not the right occurrence flag is set. Steps 128 to 136 are not performed. on the other hand,
When the right occurrence flag is set, the start winning ball counter D is incremented by 1 at step 128, and thereafter, the value of the starting winning ball counter D is incremented by 15 at step 130.
It is determined whether it is greater than. If the value is greater than 15, the right generation flag is reset in step 132 to end the right generation state, and it is determined in step 134 whether the value of the operation counter L at that time is an odd number. When the value of the operation number counter L is odd,
In step 136, a probability increase flag is set, and a green flag is set in order to indicate that the subsequent symbol displays 14a and 14b are to be displayed with a high probability of change.
As a result, the symbol displayed on the symbol indicators 14a and 14b is displayed in green, thereby notifying the player that the probability that the symbol is displayed is high.

Steps 112 to 122 described above
And Steps 132 to 136 are executed when the right generation state ends based on the passage of a hit ball to the special device operation area 5 and the predetermined number of hit balls to the starting winning opening 11 during the right generation state, and the end is an odd number. This indicates that the probability of the winning mode of the symbol display device 13 at the end of the round increases, and that the probability increase state is resolved at the start of the next right generation state. Since there is a tendency that the gaming state in which the right is generated and the gaming state in which the right is not continuously generated tend to occur alternately, the game can be inflected and the interest of the player can be attracted. Further, since the change in the probability of the hit mode can be distinguished by the color of the variable display of the symbol indicators 14a and 14b, the player can immediately know at what probability the symbol display device 13 has the variable indicator. Can be.

Further, in step 138, the winning ball number signal S4
Is detected, at step 140, the winning ball counter E is incremented by one. Step 1
When the falling of the tulip winning signal S5 is detected at 42, the value of the tulip winning counter B is set to 1 at step 144.

Next, steps 146 to 146 shown in FIGS.
The processes up to 174 and 206 are processing steps according to each state of the symbol display device 13 and the electric winning device 16, and steps 176 to 206 correspond to each state of the variable winning device 8 during the right generation state. This is a processing step.
The processing steps of the symbol display device 13 and the electric winning device 16 are performed irrespective of whether or not the right is being generated.

First, processing steps corresponding to the states of the symbol display device 13 and the electric winning device 16 will be described. (A) Processing when there is no gate winning ball When there is no gate winning ball, that is, when the gate winning counter C is 0, steps 100 to 150 and 17 are performed.
6 to 206 are performed, whereby the symbol display 1
4a, 14b, a lamp display, a lamp group, and each solenoid perform predetermined display or driving.

(B) Variation display processing In step 150, the value of the counter C is determined. When a winning is detected, the value of the counter C is decremented by one, and the register F is set to 1 to indicate the variation display state. The timer T1 is set to a predetermined value (for example, 6 seconds) (steps 152, 1
54). Then, as the gate winning counter C is decremented in step 156, the contents of the determination memory M (c) 38 are incremented by one and updated. Then step 15
It is determined at 8 whether or not the timer T1 has timed out. If it is determined that the time has expired, at step 160, the hit mode is determined from the numerical value stored in the determination memory M (0). For example, when the value of the mode determination counter is “3”, it is determined that a hit has occurred, and when the value is any other value, it is determined that the hit has occurred. And step 1
If it is determined at step 62 that it is not a hit, the process proceeds to step 164 and the values of the respective digits of the out-of-place numerical value memory 36 storing the display values in the out-of-place mode are set in the numerical value display registers X1 and X2. By doing so, the symbol display 14
In a and 14b, display numerical values in the out-of-off mode stored in the out-of-office memory 36 are displayed. On the other hand, when it is determined that a hit has occurred, the process proceeds to step 166, where the value of each digit of the hit numerical value memory 37 storing the display numerical value in the hit mode is set in the numerical display registers X1 and X2. On the symbol displays 14a and 14b, the display numerical values in the hit mode stored in the hit numerical memory 37 are displayed.

In this way, the symbol indicators 14a, 14
In b, a numerical value for display generated by a numerical value table for exclusive use and a numerical value table for hitting, which is different from the numerical value generating means for determining the mode, is displayed. Also,
Since the maximum value of the mode determination counter 35 is changed as shown in FIG. 6, the probability that the numerical value stored in the determination memory M (c) is a hit value is determined when the probability increase flag is set. It is 1/19, and when the probability increase flag is not set, it is 1/190. Until the timer T1 expires, steps 100 to 1 are executed.
46, 158, and 176 to 206 are repeated.

(C) Processing at the time of hitting If the result of the determination at step 162 is a hit, the tulip solenoid flag is set at step 168 to indicate that the tulip is being opened.
And a predetermined time (for example, 6 seconds) is set in the timer T2. The tulip solenoid 28 is energized until it is determined in step 170 that the timer T2 has timed out or in step 172 that the value of the tulip winning counter has become 1, so that the hit ball is electrically driven. The winning device 16 is kept in a state where it is easy to win. Thus, when the predetermined time has elapsed or when the value of the tulip winning counter B is set to 1, the tulip solenoid flag is reset in step 174, and the status register F and the tulip winning counter B are set to 0. As described above, when it is determined that a hit has occurred, the electric winning device 16 accepts one hit ball or opens the ball until a certain time elapses, so that the possibility that the hit ball is guided to the special winning device 4 increases. As a result, the possibility that the hit ball passes through the special device operation area 5 and becomes a right generation state is also increased. In addition, after the open state of the electric winning device 16 ends, after a predetermined interval, the variable display of the next symbol display device 13 may be started.

Next, the processing steps of the variable winning device 8 will be described. (D) Processing during the right generation state When it is determined in step 180 and step 182 that the value of the starting winning ball counter D is 1 or more and smaller than 17 and larger than the value of the opening counter G, the attacker solenoid is determined in step 184. The flag is set, and the status register H indicating that the attacker opening / closing plate 9 is being opened is set to 1. Thereafter, in step 186, the opening counter G is increased by 1. Then, in a step 188, a timer T3 for regulating the opening time of the attacker opening / closing plate 9 is set to a predetermined value (for example, 9.7 seconds).
Until it is determined that the time is up at 0 or step 192
Then, the attacker solenoid 29 is excited until the winning ball counter E reaches 10. Thereafter, when a predetermined time has elapsed or when the winning ball counter E reaches 10, the attacker solenoid flag is reset in step 194 to release the excitation state of the attacker solenoid 29, and the winning ball counter E is reset. Set to 0.

When one opening / closing state of the attacker opening / closing plate 9 is completed, an interval time is provided until the next opening / closing.
Steps 196 and 198 are performed. Then
If the interval time has elapsed, step 200
Sets the register H to 0, and determines whether or not the right generation flag is set at that time. If the right occurrence flag is set, the process immediately proceeds to step 206. If not, the value of the starting winning ball counter D and the number of open counters G is set to 0 in step 204, and the process proceeds to step 206. I do.

In step 206, the symbol display 14a,
14b, a lamp indicator and a lamp group (not shown), a tulip solenoid 28, and an attacker solenoid 29 are driven according to the state of the flag or the register. During the variable display of the symbol indicators 14a and 14b, the contents of the out-of-place numerical value table 32 are displayed in a variable manner at a speed that cannot be identified in order.

Although the embodiment has been described above, in the above embodiment, the segment LEDs are illustrated as the symbol displays 14a and 14b, but other displays may be used.
Also, numerical values of the high probability and the low probability may be arbitrarily set.
Also, the number of changes to the high probability is not limited to the end of the odd number, but may be the end of an arbitrary number or a random number.

As is apparent from the above description, in the present invention, the winning rate of the hit ball to the special winning device depends on the opening / closing drive of the electric winning device provided above the special winning device, and the winning ratio of the electric winning device is controlled. Since the opening / closing drive is only driven by the appearance of the hit symbol displayed on the symbol display device, and the appearance probability of the hit symbol is changed at the end of the predetermined number of operations of the special device. In addition, the probability that the special device operates can be changed, and the game can be inflected, and the interest of the player can be attracted.
