The pachinko gaming machine 80 is connected to the power source, and the power circuit 28
When power is supplied to each circuit from (see FIG. 4), CP
U24 initializes the stored contents of the winning storage display circuit 134 (step S1) and waits for the next signal.

When a game is started on the pachinko gaming machine 80 and a pachinko ball wins any of the start winning holes 92a, 92b, 92c, one of the detection switches 110a, 110b, 110c detects the winning ball and the starting winning circuit 136. The winning signal is given to the CPU 24 from the input / output interface 36. The CPU 24, based on this signal,
The winning memory display signal is given to the winning memory display circuit 134.
At the same time, the ramp signal is given to the ramp circuit 138,
The lamp is blinked during rotation (step S3). Further, a signal is given to the sound generation circuit 30 to generate a sound at the time of rotation (step S4). Further, a drum rotation control signal is given to the drum rotation control circuit 140 so that the rotating drums 112a, 1a
Start rotation of 12b and 112c (step S
5).

Then, in step S6, the CPU 24 determines whether or not 5.055 seconds have elapsed since the rotation of the rotary drum was started. If 5.055 seconds has elapsed, the CPU 24 randomly selects from 9 types of time. To choose one time. For example, 53.28ms, 106.496ms, 163.840
ms, 217.088 ms, 274.4432 ms, 327.6
80 ms, 380.680 ms, 438.272 ms, 49
Randomly choose one time from 1.520 ms.
Then, the process proceeds to step S10.

In addition, from the beginning 5. x s, 5. x s, 5. x s,
, 5, x s, one may be randomly selected and it may be determined whether or not the time elapses.

In step S6, if 5.055 seconds have not elapsed after the start of rotation of the rotary drum, the CPU 24
Determines whether the stop button 102 is turned on (step S7). That is, it is determined whether or not a stop signal is input from the stop circuit 142. When the step signal is not input, the CPU 24 repeats the control operation of steps S6 and S7.

When the stop signal is received, one time is randomly selected from the five types of time in step S8. For example, 196.608 ms, 397.312 ms, 598.
One time is randomly selected from 016 ms, 798.720 ms, and 946.179 ms, and the next step S10
Proceed to.

In step S10, step S8 or step S9
Wait for the next control for the time selected in. Then, after the selected time has elapsed, step S11
Go to.

In step S11, after the above time has elapsed, first, the left rotary drum 112a is stopped. This is the CPU 24
Applies a drum rotation control signal to the drum rotation control circuit 140 to deactivate the solenoid 116a.

Then, a timer is set to open a predetermined time until the central rotating drum 112b is stopped (step S12), and, for example, 1.21 seconds elapse (step S13), and the central rotating drum 112b is stopped. Is stopped (step S14).

When the rotation of the central rotating drum 112b is stopped, the drum rotation control circuit 140 causes the projectors 118a and 118b to project.
Is turned on. Then, in step S16, a timer is set to stop the right rotating drum 112c, and waits for 1.21 seconds, for example (step S17),
The rotation of the right rotary drum 112c is stopped (step S18). It is not always necessary to set the same time from the stop of rotation of the left rotary drum 112a to the stop of rotation of the central rotary drum 112b to the stop of rotation of the right rotary drum 112c. You can change to.

Then, in this state, based on the output of the pattern determination circuit 144, the display state of the rotary drums 112a, 112b, 112c is three, that is, "7", or the number of "BAR" is three.
So-called "Fever (registered trademark)" in a complete state
It is determined whether or not it is in the state (step S19).

If it is not in the "fever" state, the projector 118a,
118b is turned off (step S20), and the sound generation circuit 30
The sound output from the speaker 108 is switched to the small hit sound (step S21), and the small hit opening process is performed (step S22). For example, the opening / closing plate 88 of the variable winning ball device 90 is opened for about 0.2 seconds. Then, each lamp is turned off (step S23), and the winning prize memory display circuit 1
The winning count stored in 34 is decremented by 1, and the process returns to step S22.

In step S19, the CPU 24 causes the "fever".
When the state is determined, the light projectors 118a and 118b are turned off (step S25), a sound signal is given to the sound generation circuit 30, and a "fever" sound is output from the speaker 108. Further, a signal is given to the lamp circuit 138 to turn on or blink each lamp (step S26).

Next, in step S27, the opening / closing plate 88 of the variable winning ball device 90 is opened. This is done by the CPU 24 giving a signal to the opening control circuit 146 to turn on the solenoid 126. Then, the digital display circuit 14
A signal is supplied to 8 and the number of "fever" is displayed for 1.5 seconds by the digital display unit 96 provided in the variable display device 86. The "fever" number of times indicates how many times the open / close plate 88 of the variable winning ball device 90 has been opened.

If it is the first time, "1" is displayed for 1.5 seconds (step S28).

Then, the control of steps S29 to S34 is repeated for a predetermined time or until a predetermined number of prize balls, for example, 10 prize balls are won. That is, after the opening / closing plate 88 is opened, 3
It is determined whether or not 0 second has elapsed (step S29), 30
If the second has not elapsed, the output of the prize-winning ball detection switch 132 is given to the 1
It is determined whether or not 0 winning balls have been counted (step S30). When the number of winning balls is less than 10, each time a winning ball is detected, it is cumulatively counted, and the number is given to the 10-count display circuit 152 and displayed on the digital display 104 (step S31). ).

Further, it is determined whether or not the "fever" state is the 10th time (step S32), and if it is not the 10th time, it is determined whether or not there is a V winning (step S33). When the V winning signal is given from the V winning detection circuit 154 and the V winning is determined, the V winning lamp is turned on (step S34). The lamps are provided on both sides of the opening / closing plate 88 of the variable winning ball device 90, for example.

In step S29 or S30, the opening time of the opening / closing plate 88 has reached 30 seconds, or during that time the number of winning balls is 1
When the number of 0 has been counted, the control operation proceeds to step S35.

In step S35, the opening / closing plate 88 is closed, the "fever" state is terminated, and it is determined whether or not the "fever" state is the tenth time (step S36).

If it is not the tenth time, it waits, for example, for 1.8 seconds whether or not a signal is given from the V detection switch 130 to the V winning detection circuit 154. That is, even after the opening / closing plate 88 is closed, it waits for 1.8 seconds whether or not the V detection signal is given. (Step S37). This is because the pachinko ball that has won the winning opening 124 of the variable winning ball device 90 is
This is because it takes time to be caught by some cause, temporarily stopped, and detected by the V winning ball sensing plate 128. For example, when the pachinko ball finally wins the central portion of the variable winning ball device 90 and the player feels that there is a V winning, and the pachinko ball happens to be caught, the "fever" state is not continued. In that case, there is a possibility that a trouble may occur between the player and the clerk of the game hall where this game machine is placed, but such trouble is prevented in advance.

Then, in step S38, it is determined whether or not a V detection signal is given from the V winning detection circuit 154, and when it is determined that the V winning is performed, the sound generating circuit 30 is controlled to generate a "fever" sound. After switching, a sound during rest is output and rest time processing is performed (step S40). The pause time process is to close the opening / closing plate 88 for a predetermined time, for example, 2 seconds. During that time, the V winning lamp is turned off.

Then, the operation from step S26 is continued.

In step S36, the CPU 24 causes the "fever".
When it is determined that the state has continued for 10 times, the sound from the speaker 108 is turned off, each lamp and display are turned off,
The "fever" state is ended (step S42), and if there is a winning number stored in the winning storage display circuit 134, the winning number is decremented by 1 and the process from step S2 is continued.

The CPU 24 performs the series of processes described above and
Based on the signal interrupted by the interrupt clock circuit 156 every 4 ms, as shown in FIG.
The process of S54 is being performed.

That is, the pachinko ball in the game is the starting winning hole 92a,
Whether or not one of the 92b and 92c is won is determined based on a signal from the starting winning circuit 136, and if a pachinko ball is won in any of the starting winning holes 92a, 92b and 92c, the winning memory is stored. It is determined whether "5" is stored in the display circuit 134 (step S52), and "5" is stored.
If is not stored, the value is incremented by 1 (step S53). Then, in response thereto, the prize storing LEDs 98a, 98b, 98c, 98d are sequentially turned on from the left side to the right side. That is, these L
The EDs 98a, 98b, 98c, 98d display the number of memories stored in the winning storage display circuit 134. Then, after this interrupt processing is completed, the process returns to the routine of steps S1 to S43.

Further, in response to the operation of the operation lever 168, a drive signal is given to the drive motor, or a signal for stopping the rotary drum 162 based on an input stop signal or a signal indicating that a predetermined time has elapsed is sent to the slot machine. It is centrally given from the control board 172 provided. This control board 172 is connected to the common circuit board 1 as described in FIG.
The circuit board 14 is divided into two and the type-specific circuit board 14, and both are electrically connected.

The variable display device 86, the variable winning ball device 90, the speaker 108, or the drive motor that rotationally drives the rotary drum 162 constitutes an electric component provided in the gaming machine. The control boards 10 and 172 constitute control means for controlling electric parts provided in the gaming machine. In addition, the common circuit board 12 or the common circuit board 50 and the power supply circuit board 48 constitute a common portion that can be commonly used in a plurality of types of gaming machines. The type-specific circuit board 14 and the ROM 26 or the type-specific circuit board 52 constitute a type-specific portion specific to each type of gaming machine. Further, the connectors 16, 18 or the connectors 58, 60 constitute a connecting means for connecting the common part and the other divided parts (specific parts for each type) to electrically connect them. Since these connecting means enable data to be transmitted between the common part and the type-specific part, these connecting means allow the common part and the other divided parts (type-specific part) to be transmitted. A data transmission means that enables data transmission is configured.

With the above configuration, the following effects can be obtained. That is, when it is necessary to replace the control circuit due to a game board replacement or a minute change in the game content, it is possible to replace only the parts specific to each type, at low cost and while saving circuit components. A control circuit can be provided. This type-specific portion may be configured by a recording medium or the like in which type-specific data is stored. Further, no matter how many kinds of gaming machines, the common part can be mass-produced in one kind, so that the production cost can be reduced. Further, the divided portion other than the common portion may include a part of the common portion, and in this case, the production cost can be reduced as compared with the conventional case. Generally, various electronic circuit elements mounted on the control board are soldered by a jet method (for example, R
There are a dip type such as OM26) and a soldering method (for example, a flat type) in which a paste-like solder is printed by a reflow method. Based on such a difference in the soldering process, a control board is formed. It may be divided.

In this embodiment of the slot machine, the control board 172 is divided into the common circuit board 12 and the type-specific circuit board 14 as described with reference to FIG. By changing the separate circuit board 14, the rotation state of each rotary drum 162 can be changed, and the probability that a predetermined combination of figures displayed in the display windows 164a, 164b, 164c appears can be changed. it can. Therefore, it is possible to provide a slot machine in which it is easy to adjust the game contents while weighing the profit of the game center and the service to the customer in accordance with the business contents in the game hall, the trends of the customers, and the like.
