DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game machine such as a pachinko game machine, and more particularly, to a game machine having a variable display device including a drum, a belt, and the like on which identification information is arranged.

[0002]

2. Description of the Related Art In a gaming machine such as a pachinko gaming machine, a plurality of types of identification information (hereinafter, referred to as symbols) are variably displayed on a plurality of columns of display portions of a variable display device, and a combination of symbols at the time of stopping is previously determined. In some cases, a specific game state (big hit game state) is generated when the combination with a predetermined big hit symbol combination is reached. In the specific game state, a player is given an opportunity to generate a large number of winning balls in a short time.

[0003] The variable display of the display unit in the variable display device is started based on winning in the starting winning opening, but the display speed during the variable display is constant in order to increase a player's expectation of a big hit. is not. In the variable display device, a stepping motor is often used to variably display each display unit such as a drum and a belt on which symbols are arranged. When rotating the stepping motor at high speed,
It is necessary to quickly raise the current of the drive coil in order to prevent loss of synchronism. Therefore, a relatively high voltage is applied to the drive coil. However, if the stepping motor is rotated at a low speed, a relatively low voltage is applied to the drive coil because the efficiency at the time of the low-speed rotation is poor as it is.

In order to supply a plurality of types of motor drive voltages, for example, a motor drive circuit that outputs a high voltage and a low voltage has been used. Such a motor drive circuit inputs a control signal indicating a fluctuation speed of a drum or a belt on which symbols are arranged, and applies a relatively high voltage to a drive coil of the stepping motor when the stepping motor rotates at a high speed, thereby performing stepping. When the motor rotates at a low speed, a relatively low voltage is applied to the drive. In this way, step-out prevention at high speed and high efficiency of the stepping motor have been attempted.

[0005] In order to switch the effective drive voltage, a method of driving a stepping motor by PWM has also been proposed. That is, the pulse width duty ratio (on period / full period) of the pulse for driving the drive coil of the stepping motor is increased when the drum, belt, or the like is rotated at a high speed, and the pulse width duty ratio is decreased when the drum or belt is rotated at a low speed. According to such control, the effective drive voltage supplied to the stepping motor can be set freely, and more efficient stepping motor drive control is realized.

[0006]

However, in general, the voltage applied to the drive coils of the respective stepping motors for rotating a plurality of drums and belts is common. For example, when each stepping motor for rotating three drums is provided, when one drum is rotated at high speed, even when the other two drums are rotated at low speed, three stepping motors are used. A high voltage is applied to the drive coil of the motor. Then, a high voltage is also applied to the drive coils of the two stepping motors to which a low voltage is preferably applied. Therefore, the rotation of the drum rotating at a low speed may not be smooth.

In the PWM drive system, for example, +30
A PWM waveform based on the power supply voltage of V is applied to the drive coil of each stepping motor. However, if the power supply voltage fluctuates, a desired control state is deviated. For example, when the power supply voltage becomes +28 V while the effective predetermined current is controlled to flow through the drive coil, the effective current value flowing through the drive coil becomes smaller than a desired value.

In view of the above, the present invention provides a drive motor that is always supplied with a stable drive current irrespective of the rotation speed of a drum or a belt for variably displaying symbols, and performs stable motor control even when the power supply voltage fluctuates. It is an object of the present invention to provide a gaming machine that can perform the game.

Next, the operation of the gaming machine will be described. FIG.
Is a flowchart showing a game control operation executed by the CPU 356 on the main board 331 according to the game control program. This process is activated by a reset pulse generated by the periodic reset circuit 66, for example, every 2 ms. When the CPU 356 is activated, the CPU 356 first sets the clock monitor control to an operable state.
The clock monitor register built in the CPU 356 is set to the clock monitor enable state (step S1). Note that the clock monitor control means that when a decrease or stop of the input clock signal is detected, the CPU 35
6 automatically generates a reset.

Next, the CPU 356 performs a stack setting process for setting the designated address of the stack pointer (step S2). In this example, 00FFH is set in the stack pointer. Then, a system check process is performed (step S3). In the system check processing, the CPU 356 determines whether or not the RAM 355 contains an error.
Processing such as initializing the AM 355 is performed.

Next, after processing for setting command data sent to the display control board 165 to a predetermined area of the RAM 355 is performed (display control data setting processing: step S
4) Perform processing for outputting command data as a display control command (display control data output processing: step S)
5).

Next, processing for outputting the contents of the storage area for various output data to each output port is performed (data output processing: step S6). Further, the lamp timer is decremented by one, and when the lamp timer times out (when it becomes 0), the lamp data pointer is updated and a new value is set in the lamp timer (lamp timer processing: step S7).

Further, output data setting processing for setting output data such as data of the address indicated by the lamp data pointer, jackpot information, start information, and probability variation information output to the hall management computer in the storage area is performed (step S8). ). Further, various abnormality diagnosis processes are performed by a self-diagnosis function provided inside the pachinko gaming machine 1, and an alarm is issued if necessary according to the result (error process: step S9).

Next, a process of updating each counter indicating each random number for determination, such as a random number for determining a jackpot used for game control, is performed (step S10).

Next, the CPU 356 performs a special symbol process (step S11). In the special symbol process control, a corresponding process is selected and executed according to a special symbol process flag for controlling the pachinko gaming machine 1 in a predetermined order according to a gaming state. Then, the value of the special symbol process flag is updated during each processing according to the gaming state. Further, a normal symbol process is performed (step S12). In the normal symbol process process, a corresponding process is selected and executed according to a normal symbol process flag for controlling the normal symbol display 44 in a predetermined order. Then, the value of the normal symbol process flag is updated during each process according to the gaming state.

Further, the CPU 356 includes the switch circuit 3

The CPU 356 further performs a process of updating the display random number (step S15). CPU3
56 performs signal processing with the award ball control board 98 (step S16). That is, when a predetermined condition is satisfied, a prize ball control command indicating the number of prize balls is output to the prize ball control board 98. The prize ball control CPU mounted on the prize ball control board 98 drives the ball payout device 97 in accordance with the received number of prize balls. After that, the basic circuit 53 repeats the display random number updating process in step S17 until the next reset pulse is given from the periodic reset circuit 66.

FIG. 10 is a flowchart showing an example of a special symbol processing program executed by the CPU 356. The special symbol processing shown in FIG.
Is a specific process of step S11 in the flowchart of FIG. When performing the special symbol process processing, the CPU 356 performs any one of steps S300 to S309 shown in FIG. 10 according to the internal state. In each process, the following processes are performed.

Special symbol change waiting processing (step S30)

Wait for 0 to turn on. When the starting port switch 50 is turned on, if the number of stored start winnings is not full, the number of stored starting winnings is incremented by one, and a random number for determining a big hit is determined for determining whether or not to make a big hit.

Special symbol determination processing (step S301):
When a state in which the variable display of the special symbol can be started on the variable display device 26 is started, the number of start winning storages is confirmed. If the starting prize storage number is not 0, it is determined whether to make a big hit or a non-big hit according to the value of the extracted big hit determining random number.

Stop symbol setting processing (step S302):
The stop symbol of the left and right middle symbols is determined.

Reach operation setting processing (step S30)
3): Determine whether or not to perform the reach operation according to the value of the random number for determining whether to reach or not, and determine the fluctuation period at the time of reach according to the value of the random number for determining the type of reach. I do.

All symbols change start processing (step S30)
4): The variable display device 26 is controlled so that all symbols start to change. At this time, the right and left final stop symbols and information instructing a change period are transmitted to the display control board 165.

All symbols stop waiting processing (step S30)
5): After a predetermined time has elapsed, control is performed so that all symbols displayed on the variable display device 26 are stopped. If the stop symbol is a combination of big hit symbols, the internal state (process flag) is updated so as to shift to step S306. If not, the internal state is updated to shift to step S300.

Big hit display processing (step S306): Control for notifying the player of the big hit is performed.

Grand opening opening process (step S30)
7): Control for opening the special winning opening is started. Specifically, the counter and the flag are initialized, and the solenoid 54 is driven to open the special winning opening.

Processing during opening of the special winning opening (step S30)
8): Monitor the count switch 56 and display the winning number display 5
Control such as updating the display number of 8 is performed. When the final closing condition of the special winning opening is satisfied, the internal state is updated so as to shift to step S309.

Big hit end processing (step S309): Control is performed to notify the player that the big hit gaming state has ended. After that, the internal flags etc. are returned to the initial state,
The internal state is updated so as to shift to step S300.

FIG. 11 is an explanatory diagram showing a configuration example of display control command data based on 8-bit data transmitted from the main board 331 to the display control board 165. As shown in FIG. 11, for example, the upper 4 bits of the 8 bits indicate the type of control, and the lower 4 bits indicate the specific control content. For example, in this example, the upper 4 bits are [0,
[0, 0, 1], the lower four bits of the numerical value indicate the symbol change period, stop all symbols, and the like. If the upper 4 bits are [1, 0, 0, 0], the stop symbol of the left symbol variably displayed on the variable display device 26 is indicated by the numerical value of the lower 4 bits.

FIG. 12 is an explanatory diagram showing signal lines of a display control command transmitted from the main board 331 to the display control board 165. As shown in FIG. 12, in this embodiment, the display control command is the display control command data D0.
The signal is transmitted from the main board 331 to the display control board 165 by eight signal lines of D7 to D7. A signal line for a display control INT signal for transmitting a strobe signal and a signal line for supplying a ground level are also provided between the main board 331 and the display control board 165.

FIG. 13 is a timing chart showing an example of the transmission timing of the display control command given from the main board 331 to the display control board 165. In this example, when the display control command data is output, as shown in FIG.
The INT signal goes low for a short period (for example, 5 μs). The display control CPU 401 can fetch the display control command data by, for example, an interrupt process based on the INT signal.

Note that, when a display control command data transmission request is generated, the CPU 356 of the main board 331 outputs the display control command data to the output port 571 only once and outputs the INT signal only once. Therefore, the load required for command transmission of the game control means does not increase so much.

Is sent to each of. The display control board 165 further sends a symbol designating command indicating a fixed symbol of the left and right middle symbols.

When the symbol variation is determined, a variation stop command is sent to each of the display control board 165, the sound control board 97, and the lamp control board 85. Each CPU mounted on the display control board 165, the sound control board 97, and the lamp control board 85 performs display control, sound generation control, and lamp lighting control according to the variation mode designated by the variation start command. The change start command includes information indicating the change time.

FIG. 15 shows a switching circuit 191.
Although only the configuration example of A is shown, the switching circuit 1
The configuration of 91B and the switching circuit 191C is the same as the configuration of the switching circuit 191A.

The display control CPU 401 monitors the +30 voltage via the AD converter 410. When the value deviates from +30 V, the switching circuit 191A,
The duty ratio of the switching signal provided to 191B and 191C is adjusted.

Further, the display control CPU 401 sends the drum motors 200 A, 200 A through the output port 511.
A motor drive signal for driving each of the drive coils B and 200C is output. Motor drive signals from the output port 511 are supplied to drive circuits (amplifier circuits) 176A, 176B,

This is a drive control circuit that controls 200C.

9C is installed. Drum sensors 139A, 139
The detection signals of B and 139C are input to the display control CPU 401 via the amplifier circuit 177 and the input port 521. The drum sensors 139A, 139B, 139
C is supplied with a +12 V voltage from a power supply substrate.

FIG. 16 is a block diagram showing an example of a configuration of a portion related to driving of the drum lamps 151A to 151C in the display control board 165. In this example, each of the drum lamps 151A to 151C includes three white lunar lights (hot cathode tubes) and two red lunar lights.

One of the two filament-side terminals of each lunar light is grounded, and a heater drive voltage is applied to the other. The anode is connected to the output port 511 and the drive circuit (amplifier circuit) 17 from the display control CPU 401.
Lighting signals are applied via 8A, 178B, 178C. The lunar light emits light when a lighting signal is applied to the anode while the heater drive voltage is being applied and the filament is being heated.

As shown in FIG. 16, in this embodiment, the heater driving voltages of the three white lunar lights and the heater driving voltages of the two red lunar lights in each of the drum lamps 151A to 151C are controlled by different systems. Have been. In this example, a control signal for driving a red lunar light and a control signal for driving a white lunar light are independently output from a built-in output port of the display control CPU 401. Further, all the filaments of the white lunar light of each of the drum lamps 151A to 151C are driven by one heater driving voltage, and all the filaments of the red lunar light are driven by one heater driving voltage. In this embodiment, all the white Luna lights blink synchronously and all the red Luna lights blink synchronously. Therefore, there is no problem even if all the white lunar lights and all the red lunar lights are each driven by one heater driving voltage.

The control signal for driving the red lunar light from the CPU 401 for display control becomes a switching signal of the switching circuit 178D. The switching circuit 178D supplies +
A 5.4V voltage is supplied to or cut off from the red lunarite filament of each of the drum lamps 151A to 151C. The white luna light drive control signal is a switching signal of the switching circuit 178E. The switching circuit 178E applies the + 5.4V voltage supplied from the power supply board to each of the drum lamps 15 according to the switching signal.
It feeds or blocks filaments of white lunarite from 1A to 151C. The switching circuit 178
D and 178E are heater voltage control means for the lunar light which is a light emitting element.

Next, the rotation control of the drum motors 200A to 200C will be described with reference to FIG. 17 and FIGS.
This will be described with reference to the waveform diagram of FIG. In this embodiment, as shown in FIG.
From 1, a change start command indicating a change period and a symbol designating command indicating a fixed symbol in the left and right are transmitted to the display control board 165. The display control CPU 401 of the display control board 165 independently selects one variation pattern from a plurality of variation patterns defined according to the variation period specified by the received variation start command. Then, according to the selected variation pattern, the rotating drum 122A
Drum motors 200A-200 for rotating ~ 122C
The driving of C is controlled.

As an example, assume that a variation pattern as shown in FIG. 17A is selected. That is, the left and right middle drums start low-speed rotation (actually, the rotation gradually increasing in speed), and then shift to high-speed constant speed rotation in the left-right middle order, and then low-speed rotation in the left-right middle order ( In practice, the rotation shifts so that the speed gradually decreases. Then, the left and right drums stop. Furthermore, the middle drum rotates again at a high speed, and then stops at a low speed (actually, the speed gradually decreases).

In realizing such a fluctuation pattern,
The switching circuits 191A, 191B, and 191C first output a high-duty PWM waveform having a long on-period as shown in FIG. 17B in response to a switching signal from the display control CPU 401. That is, a high voltage is applied to the drive coils of the drum motors 200A to 200C. At the start of rotation, a high torque is required, so that a high voltage is first applied to the drive coils of the drum motors 200A to 200C.

Thereafter, the display control CPU 401 switches the switching circuits 191A, 191B, 191C according to the rotation speeds of the respective drum motors 200A to 200C.
Are instructed as to whether the duty is high or low. Therefore, the switching circuit 1
Each of the switching circuits 91A, 191B, and 191C outputs a low-duty PWM waveform when the corresponding drum rotates at a low speed, and outputs a high-duty PWM waveform when the corresponding drum rotates at a high speed, independently of the other switching circuits. Therefore, a high voltage is applied to a drive coil of a drum motor that drives a high-speed rotating drum, and a low voltage is applied to a drive coil of a drum motor that drives a low-speed rotating drum.

As described above, the rotation speed (variation speed)
When the speed is high or when high torque is required, FIG.
8, the drum motors 200A, 200B, 2
A PWM waveform having a long ON period is applied to the drive coil of 00C. When the fluctuation speed is slow or low torque is sufficient, a PWM waveform with a short ON period is applied. A PWM waveform having a long ON period corresponds to a in FIG. 18, and a PWM waveform having a short ON period corresponds to b in FIG. 18.

Note that the display control CPU 401 determines that the fluctuation speed is fast when the fluctuation speed is 20 ms / step or less, for example, and judges that the fluctuation speed is slow when the fluctuation speed exceeds 20 ms / step. judge. However, this value is merely an example value, and fast / slow is determined according to the model or drum type applied.

From the above description, equivalently, when the motor rotates at a high speed or when a high torque is required, the high voltage is applied to the drum motor 2.
00A to 200C are applied to the drive coil, and a low voltage is applied to the drive coil during low-speed rotation.

Further, the display control CPU 401 controls the driving circuits 176A, 176B, 17 via the output port 511.
6C is supplied with a motor drive signal for driving the drum motor. The drive circuits 176A, 176B, and 176C amplify the motor drive signal from the output port 511 and drive the respective drive coils of the drum motors 200A, 200B, 200C.

FIG. 19 is a timing chart showing an example of a motor drive signal for the drum motor 200A and an effective drive voltage. When rotating the drum motor 200A at a high speed, the display control CPU 401 gives a high duty switching signal to the switching circuit 191A. Therefore, a +30 V pulse having a long ON period is output from the switching circuit 191A. Therefore, the effective drive voltage for the drum motor 200A is high.

In this state, the display control CPU 401
A motor drive signal of a predetermined frequency is output to drive circuit 176A via output port 511. The predetermined frequency is a frequency corresponding to the rotation speed of the drum motor 200A. For example, if there are 20 symbols on the rotating drum 122A that is driven to rotate by the drum motor 200A and it takes eight steps to change one symbol, when changing one symbol in 0.2 seconds, it is equivalent to 40 steps / second. And outputs a motor drive signal of the desired frequency.

When the drum motor 200A is rotated at a low speed, the display control CPU 401 supplies a low duty switching signal to the switching circuit 191A.
Therefore, a +30 V pulse with a short ON period is output from the switching circuit 191A. Therefore, the drum motor 2
The effective drive voltage for 00A is low. In that state,
The display control CPU 401 outputs a motor drive signal having a frequency corresponding to the low-speed rotation to the drive circuit 176A via the output port 511.

As described above, the display control CPU 401
Supplies a high-duty switching signal to the switching circuit 191A when outputting a high-frequency motor drive signal, and supplies a low-duty switching signal to the switching circuit 191A when outputting a low-frequency motor drive signal. Therefore, during high-speed rotation, a high voltage is applied to the drum motor 200A, and the drum motor 200A
Rotates stably. On the other hand, during low-speed rotation, a low voltage is applied to the drum motor 200A, and power consumption is reduced.

The display control CPU 401 supplies a high-duty switching signal to the switching circuit 191A even at the start of motor rotation requiring high torque, and controls the drum motor 200A to start rotating stably. Also, the control related to the drum motor 200A has been described here, but the drum motors 200B and 200B are not described.
C is similarly controlled.

Further, in this embodiment, as shown in FIG. 19, at each of the high speed and the low speed, each drum motor 200
The drive coils of A, 200B, and 200C are two-phase excited, but may use a 1-2-phase excitation method.

In this embodiment, the switching circuits 191A, 191B, and 191C are provided corresponding to the respective drum motors 200A, 200B, and 200C, so that step-out occurs for each of the drum motors 200A, 200B, and 200C. It is possible to perform a stable control that does not cause the like. As a result, the rotating drums 122A, 12A
2B and 122C always rotate stably, and the interest of the game is not spoiled.

For example, even when one variable display device 26 includes rotating drums having different inertia, that is, even when rotating drums having different drum diameters exist, the switching circuits 191A, 191B,
191C is each drum motor 200A, 200B, 200
C is provided so that appropriate speed control and torque control can be performed for each rotating drum.

In this embodiment, the display control C
The PU 401 is connected to the drive circuit 17 via the output port 511.
Motor drive signals are given to 6A, 176B and 176C.
Therefore, even if an abnormality occurs on the side of the drum motors 200A, 200B, 200C, its influence is not affected by the display control CPU 40.
It does not pass to one. That is, the display control CPU 4
01 can be protected.

Further, as shown in FIG. 20, the speed can be easily switched. That is, when the display CPU 401 shifts from the high-speed rotation to the low-speed rotation, as shown in FIG.
Duty ratio P1 intermediate between duty ratio P2 at low speed
Is output. By doing so, the drum motors 200A, 200
0B and 200C rotate, a current suitable for the rotation is supplied to the drum motor 2
00A, 200B, and 200C.

Therefore, in the conventional case, even when a motor drive signal that causes step-out occurs, the current applied to the drive coils of the drum motors 200A, 200B, 200C can be freely changed by PWM control. As a result, step-out can be prevented, and switching of the fluctuation speed is smoothly performed. Also, an appropriate current can be supplied depending on the time, heat generation of the coil due to overcurrent or the like can be suppressed, and an efficient current can be supplied. For example, if the drum motors 200A, 200B, and 200C are controlled to generate high torque at low speed rotation, idling will occur, and if the drum motors 200A, 200B, and 200C are controlled to generate low torque at high speed rotation, step-out and the like will occur. However, in this embodiment, it is possible to perform control such that high torque is generated at high speed rotation and low torque is generated at low speed rotation.
0C always rotates stably.

Therefore, compared to the conventional case, many types of variation patterns can be realized. This makes it possible to realize a gaming machine that gives the player a sense of expectation. Further, when driving a rotary drum having a different inertia due to a change in a game machine or the like, it is not necessary to change the motor to match the rotary drum to be used, so that a versatile gaming machine can be realized.

FIG. 21 is a waveform diagram for explaining the operation of the AD converter 410. The A / D converter 410 converts the value of the power supply voltage into a corresponding digital value and provides the digital value to the display control CPU 401. The display control CPU 401 includes:
A value corresponding to a regular power supply voltage (reference voltage) is compared with a conversion value from the A / D converter 410. When the conversion value from the A / D converter 410 is smaller than the value corresponding to the reference voltage, that is, when the actual power supply voltage is lower than the normal power supply voltage, as shown in FIG. And PW
The ON period of the M waveform 211 is lengthened. When the conversion value from the A / D converter 410 is larger than the value corresponding to the reference voltage, that is, when the actual power supply voltage is higher than the normal power supply voltage, FIG. As shown, the ON period of the PWM waveform 211 is shortened.

By controlling as described above, the current waveform applied to the drive coils of the drum motors 200A, 200B, 200C is changed as shown in FIGS. 21 (B), (D) and (F). Even at this time, the current value can be kept constant. That is, the torque of the drum motors 200A, 200B, and 200C becomes constant irrespective of the fluctuation of the power supply voltage, and more stable symbol fluctuation is realized.

As described above, in this embodiment, A-
Since the D converter 410 is provided, the display control CP
U401 creates the PWM waveform 211 based on both the symbol fluctuation speed and the conversion value from the A / D converter 410. The display control CPU 401 may always monitor the conversion value from the AD converter 410, or may monitor the conversion value at predetermined time intervals.

In the above-described embodiment, the display control CPU 401 determines a specific symbol variation pattern based on a display control command that can specify the variation time received from the main board 331. In other words, one out of a plurality of fluctuation patterns determined for the same fluctuation time
The two fluctuation patterns. Although the determined fluctuation pattern includes a plurality of fluctuation periods of different speeds, the display control CPU 401 determines the fluctuation pattern by itself, so that the PWM waveform 21 corresponding to each speed in the fluctuation pattern is displayed.
1 can be determined immediately.

That is, the display control CPU 401 determines a specific variation pattern from the received display control command, and sets the drum motors 200A, 200B, 200C.
Is configured to generate a PWM waveform for performing PWM control of the drum motors 200A, 200B, and 200C while providing a pulse-shaped motor drive waveform to the The appropriate duty ratio of the PWM waveform can be immediately determined from the fluctuation speed in each fluctuation period.
Therefore, the motor control program executed by the display control CPU 401 is not complicated, and various effects such as easy maintenance of the program can be obtained.

In the above embodiment, the case where the variable display device 26 having the rotating drum is used has been described. However, the present invention can be applied to a variable display device having another structure. For example, even when a belt-type variable display device that rotates a belt on which a pattern is drawn is used, if the switching circuits 191A, 191B, and 191C are provided corresponding to the stepping motors for driving each belt, each belt can be used. Appropriate speed control and torque control can be performed. Also, the AD converter 41
An appropriate PWM waveform corresponding to the output of 0 can be generated.

Further, the present invention can be applied to a case where a variable display device other than the drum type or belt type variable display device is used. That is, as long as the game machine has a variable display device in which a symbol is changed by a stepping motor, the present invention can be applied to a gaming machine having a variable display device of another method. Further, in the above embodiment, the case where the stepping motor is used has been described, but the motor is not limited to the stepping motor. A servo motor, a DC motor, or the like may be used.

Next, the lighting control of the lunar light used as the drum lamps 151A to 151C will be described. As described above, the lunar light emits light when a lighting signal is applied to the anode in a state where the heater driving voltage is applied and the filament is heated. In this embodiment, as shown in FIG.
The heater drive voltages of the three white lunar lights and the heater drive voltages of the two red lunar lights in 51A to 151C are controlled by different systems. That is, the control signal for driving red luna light and the control signal for driving white luna light are output independently from the built-in output port of the display control CPU 401.

The display control CPU 401 includes a main board 331
The specific variation pattern is determined based on the display control command received from, but it is also determined whether or not to execute various game effects other than the variation pattern. For example,
It is also determined whether or not to perform a notice effect for notifying the player of the possibility of a big hit. In this embodiment, it is assumed that the announcement effect is performed by blinking the red lunar light. Also, it is assumed that the white lunar light blinks during the rotation of the rotating drums 122A to 122C and is used as one that enhances the game effect.

FIG. 22 is a flowchart showing the main processing executed by the display control CPU 401. When the power is turned on, the display control CPU 401 first executes initialization processing for performing processing such as initializing a RAM and an output port (step S701). Then, it waits until the timer interrupt flag becomes 1 (step S702).
When the timer interrupt flag becomes 1, the timer interrupt flag is cleared (step S703), and the display control process (step S704) is executed. Step S
In the initialization processing of 701, initialization is also performed such that the internal timer of the display control CPU 401 repeatedly times up at a predetermined interval (for example, 2 ms).

In the initialization process, each drum lamp 1
The setting to start supplying the heater drive voltage for heating the filament of white lunarite in 51A to 151C is also made. That is, a signal for turning on the switching circuit 178E is output (see FIG. 16).

FIG. 23 is a flowchart showing the timer interrupt processing. In the timer interrupt processing, the display control CPU
401 sets a timer interrupt flag (step S
711). In this embodiment, since the timer interrupt occurs at a predetermined interval such as every 2 ms, the display control process of step S704 is restarted at a predetermined interval. If it is not possible to set the internal timer to repeat the time-up,
The timer setting process is performed again. Further, the display control process may be executed by a timer interrupt process.

FIG. 24 shows a display control process (step S70).
It is a flowchart which shows the display control process process which is an example of 4). In the display control process, steps S720 to S840 are performed according to the value of the display control process flag.
Is performed. In each process,
The following processing is executed.

Display control command reception waiting process (step S720): It is confirmed whether or not a display control command capable of specifying the fluctuation time has been received from the main board 331.

Reach operation setting processing (step S75)
0): At the time of the reach, which of the fluctuation patterns determined as the reach mode is used is determined. In addition, it is determined whether or not to perform the jackpot notice, and if it is determined to perform the notice, the type of the notice is determined.

All symbols change start processing (step S78)
0): Control is performed so that the change of the middle left and right symbols is started.
That is, the drum motors 200A, 200B, 200C
Circuit 191A, 1 for supplying a PWM waveform to
91B and 191C are turned on.

Symbol change processing (step S810): The switching timing of each change state (change speed) constituting the change pattern is controlled, and the end of the change time is monitored. Also, stop control of the left and right symbols is performed.

All symbols stop wait setting processing (step S84)
0): At the end of the fluctuation time, if a display control command instructing to stop all the symbols has been received, the fluctuation of the symbols is stopped and the rotating drums 122A to 122A are stopped at the final stopped symbol (fixed symbol).
Control to stop C is performed.

FIG. 25 is an explanatory diagram showing the relationship between the jackpot announcement random number and the jackpot announcement among the display random numbers handled by the display control CPU 401. As shown in FIG. The display random numbers include a reach type determination random number and a jackpot announcement random number. The reach type determination random number is used to determine a fluctuation pattern (reach type), and the jackpot announcement random number is used to determine whether or not to perform a jackpot announcement.

FIG. 26 is a flowchart showing the reach operation setting process (step S750). In the reach operation setting process, the display control CPU 401 determines from the display control command that can specify the fluctuation time whether or not it is out of reach (step S751).

If so, it is checked whether or not the left and right stop symbols (stop symbols specified by the display control command) are different (step S752). If they match, the right stop symbol is assumed to be shifted by one symbol (step S753). Then, the left and right stopped symbols are stored in a predetermined storage area (step S754).

If it is determined in step S751 that there is no loss, it is checked whether the left and right stopped symbols are the same (step S755). If not, the right stop symbol is made the same as the left stop symbol (step S756). Then, the left and right middle stop symbols are stored in a predetermined storage area (step S757). Also, the display control CPU 401
Determines the reach type, that is, the fluctuation pattern (step S758). In addition, it is determined whether or not to perform the big hit notice (step S759).

As described above, in this embodiment, the display control CPU 401 contradicts the command sent from the main board 331 and the received left and right middle stop symbol when starting the variable display of the symbol. Sometimes stop symbols are corrected. Therefore, even if an error occurs in the display control command designating the left and right middle stop symbol for some reason, the error is corrected. The error is, for example, a case in which noise is present on the cable from the main board 331 to the display control board 165 and a bit error occurs in the command. As a result,
The display of the fixed symbol inconsistent with the loss / reach determined by the game control means is prevented.

In this embodiment, it is assumed that the symbol variation control, that is, the speed control of the drum motors 200A, 200B, 200C is performed using a process table corresponding to the selected variation pattern. The process table contains
Information indicating the speed switching timing and the speed after the switching is set. Therefore, in the reach operation setting process, it is also determined to use a process table corresponding to the selected variation pattern. Then, the display control CPU 401 changes the value of the display control process flag to a value corresponding to the all symbol variation start processing (step S780) (step S76).
0).

FIG. 27 is a flowchart showing the reach mode determination processing in step S758. In the reach mode determination process, the display control CPU 401 first extracts a reach type determination random number (step S758a).
Then, the reach type is determined using the table in which the relationship between the random number value and the variation pattern is described (step S7).
58b).

FIG. 28 is a flowchart showing the jackpot announcement determination process in step S759. In the jackpot announcement determination process, the display control CPU 401 first extracts a jackpot announcement random number (step S759a). Then, it is confirmed whether or not to make a big hit (step S759)
b). The confirmation is performed using a display control command indicating a left and right middle stop symbol received from the main board 331. If a big hit is not to be made, it is determined whether or not to make a big hit notice using the table shown on the right side of FIG. 25, and if a big notice is to be made, the mode of the notice is determined (step S759c). If a big hit is to be made, it is determined whether or not to make a big hit notice using the table shown on the left side of FIG. 25, and if a big notice is to be made, the mode of the notice is determined (step S75).
9d).

If it is determined that the big hit notice should be given, the big hit notice start time determination timer is started (steps S759e and S759f). The big hit notice start time determination timer is a timer that determines the time from the start of the symbol change to the start of the big hit notice 1 mode. In the embodiment of the big hit notice 1, in this embodiment, the red lunar lights of the drum lamps 151A to 151C are blinked and displayed.

Then, the display control CPU 401 starts the red lunar light lighting preparation timer (step S).
759 g). The red lunar light lighting preparation timer is for setting a timing to start supplying a heater driving voltage for heating the filament of the red lunar light in each of the drum lamps 151A to 151C. When the red lunar light lighting preparation timer times out, the display control C
The PU 401 outputs a signal for turning on the switching circuit 178D (see FIG. 16). In this embodiment, the setting is made such that the red lunar light lighting preparation timer times out two seconds earlier than the big hit notice start time determination timer times out.

FIG. 29 is a diagram showing a process during symbol change (step S8).
It is a flowchart which shows 10). In the symbol variation processing, the display control CPU 401 checks whether the red lunar light lighting preparation timer has timed out (step S811). If it has timed out, the switching circuit 17 for heating the filament of red lunarite
8D is turned on (step S81)
2). The switching circuit 178D applies + 5.4V to the non-ground side of the two terminals of the filament of each red lunar light according to the signal.

Further, it is confirmed whether or not the timer for determining the jackpot notice start time has timed out (step S81).
3). If the timeout has occurred, the flashing control of each red lunar light is started so that the mode of the big hit notice 1 is performed (step S814). More specifically, the output port 511 and the driving circuits 178A, 178 at a predetermined blinking interval.
B and 178C (see FIG. 16), an ON signal and an OFF signal are repeatedly applied to the anode of each red lunar light.

If it is determined that the notice by the jackpot notice 2 is to be performed (step S815),
The big hit notice 2 start time determination timer is started (step S816). In this embodiment, the jackpot notice 2
Is a development of jackpot notice 1. Accordingly, the announcement by the jackpot announcement 2 is performed a predetermined time after the announcement by the jackpot announcement 1 is started (until the timeout of the jackpot announcement 2 start time determination timer).

The display control CPU 401 checks whether or not the big hit notice 2 start time determination timer has timed out (step S817). If the timeout has occurred, the drum motors 200A, 200B, and 200C are controlled so that the display according to the big hit notice 2 is performed (step S818). The mode of the big hit notice 2 will be described later.

Next, the display control CPU 401 checks whether or not the process timer has timed out (step S819). When the process timer times out, the pointer indicating the data in the process table is set to +
3 is performed (step S820). The reason for adding +3 is that, in the process table, information indicating each fluctuation period constituting the fluctuation pattern is described in 2 bytes, and information indicating the fluctuation speed in that period is described in 1 byte.

Then, it is determined whether or not the data in the area pointed to by the pointer is an end code (step S821).
If it is not the end code, the drum motors 200A, 200B, 200C are based on the data indicating the fluctuation speed set in the third byte of the process data indicated by the pointer.
And the drive signal for the drive coil is controlled (step S822). For example, if the data indicating the fluctuation speed indicates a high-speed fluctuation, the duty ratio of the PWM waveform is increased and a motor drive signal having a frequency corresponding to the fluctuation speed is output. Further, the timer is started with the process timer value set in the first and second bytes (step S823).

At step S821, if it is the end code, the rotating drum 122A, 1
After performing the control to stop 22B and 122C (step S824), the value of the display control process flag is changed to a value corresponding to the display control command reception waiting process (step S720) (step S825).

As described above, the rotating drum 122A,
The fluctuation control of the symbol based on the rotation of 122B and 122C is performed, and during this time, if it is determined to perform the jackpot announcement, the jackpot announcement effect by blinking the red lunar light is executed.

FIG. 30 is an explanatory diagram showing the relationship between the jackpot announcement effect and the rotation of the rotary drums 122A, 122B, 122C in this embodiment. FIG. 30 (A) is an example of a case where the big hit notice 1 is executed. As shown in the figure, when a predetermined time has elapsed from the start of the fluctuation, the filament heating control of red lunalite is started. As described above, in this embodiment, the predetermined time is a period in which the start of heating is two seconds before the start of the big hit announcement effect.

Accordingly, two seconds after the start of filament heating of the red lunar light, the display control CPU 401 starts blinking control of the red lunar light. Then, at the end of the flashing control of the red lunar light, the display control CPU 401 releases the heating of the filament of the red lunar light. That is, the switching circuit 178D shown in FIG. 16 is turned off. In this example, the white lunar light is always set to a blinking state while the symbol is changing. The flashing control method is the same as in the case of the red lunar light.

FIG. 30 (B) shows an example of the case where the big hit notice 2 is made. In the big hit notice 2, the left and right rotating drums 122A and 122C for changing the left and right symbols rotate after a predetermined time has elapsed after the red lunar light starts blinking. Same as in the case.

As described above, according to this embodiment,
When the red lunar light does not blink, the heating of the red lunar light filament is stopped. Therefore, power consumption can be reduced and the life of the lunar light can be extended.

Specifically, the heating of the filament is started a predetermined time before the flashing of the red lunar light starts, that is, since the filament is preheated, the luminous energy rises immediately, and the luminous energy is insufficient at the start of the flashing. I haven't. Therefore, the interest of the game is not spoiled.

As shown in FIG. 16, all the white lunar lights of the left and right drum lamps 151A to 151C are controlled by one heater driving signal, and all the red lunar lights are controlled by one heater driving signal. Therefore, the control can be simplified and the circuit scale can be reduced.

Further, in this embodiment, the display control CPU 401 determines whether or not to perform the jackpot notice, and performs the preheating start control and the anode on / off control (flashing control) of the red lunar light used in the jackpot notice. The display control CPU 401
Can determine immediately the preheating start timing and the anode ON / OFF control start timing when it is determined to perform the jackpot notice. Accordingly, the drum lamps 151A to 151A
Control of 51C is easy. Further, since the game control means does not control the drum lamps 151A to 151C at all, the load on the game control means is reduced.

Although the present embodiment has been described with respect to the case where a big hit notice is given, a reach notice may be given. In addition, the notice effect was illustrated as a use form of the lunar light in which the heater heating is turned off when not in use,
The mode of use of Lunalight is not limited to notice production. The present invention can be applied to lunar lights that are used only for a specific period during the game, regardless of the purpose of using the lunar lights. For example, when the fluctuation pattern determined by the display control CPU 401 is a specific fluctuation pattern such as super reach, a usage method of deciding to use a specific lunar light (for example, red lunar light) during the fluctuation period is adopted. You can also.

Further, in the above-described embodiment, the lunar light mounted in the variable display device or in the vicinity of the variable display device has been described as an example. In this case, the present invention can be applied.

Further, the scope of application of the present invention is not limited to lunar lights, and is applicable to a light emitting element used in a game machine, which has an input terminal for controlling heating and the like in addition to an input terminal for controlling blinking. The present invention can be applied to the light emitting element of the above.
