That is, the game ball is fired about every 0.6 seconds.
The ball feed solenoid 12b is composed of a linear solenoid, and sends out the game balls on the upper plate 6a (see FIG. 1) one by one toward the launching member directly connected to the firing solenoid 12a.

The lamp control board 140 is connected to the effect control board 120 so as to be capable of bidirectional communication, and an effect button detection switch 8a provided on the effect button 8 is connected to the input side of the lamp control board 140. When a detection signal is input from 8a, it is output to the effect control board 120.
The lamp control board 140 is connected to the effect accessory device 32 and the effect lighting device 33 provided on the game board 10, and the lamp control board 140 is connected to the data transmitted from the effect control board 120. Based on this, lighting control of the lighting device for effect 33 is performed, or drive control for the motor for changing the light irradiation direction is performed. In addition, energization control is performed on a drive source such as a solenoid or a motor that operates the effect accessory device 32. In the present embodiment, the production effect device 32 includes the production buttons 8 because the production buttons 8 are configured to protrude.

  The image control board 150 is connected to the effect control board 120 so as to be capable of bidirectional communication, and the image display device 31 and the audio output device 34 are connected to the output side thereof.

<Image control board configuration>
Here, the configuration of the image control board 150 will be described with reference to FIG.
FIG. 4 is a block diagram showing the configuration of the image control board.
The image control board 150 includes a host CPU 151, host RAM 152, host ROM 153, CGROM 154, crystal oscillator 155, VRAM 156, and VDP (Video Display Processor) 200 for performing image display control of the image display device 31.
As will be described later, the VDP 200 includes a voice control circuit 300 for controlling voice output in the gaming machine.

The host CPU 151 instructs the image display device 31 to display the image data stored in the CGROM 154 on the VDP 200 based on the later-described effect pattern designation command received from the effect control board 120. Such an instruction is performed by setting data in the control register 201 of the VDP 200 and outputting a display list including drawing control command groups.
In addition, when receiving a V blank interrupt signal or a drawing end signal from the VDP 200, the host CPU 151 appropriately performs an interrupt process.

Further, the host CPU 151 also instructs the audio control circuit 300 included in the VDP 200 to output predetermined audio data to the audio output device 34 based on the effect pattern designation command received from the effect control board 120.
The host RAM 152 is built in the host CPU 151, functions as a data work area when the host CPU 151 performs arithmetic processing, and temporarily stores data read from the host ROM 153.

The host ROM 153 is composed of a mask ROM, and displays a program for controlling the host CPU 151, symbol arrangement information in which the symbol number of the effect symbol is associated with the type of the effect symbol 35, and a display for generating a display list. A list generation program, an animation pattern for displaying an animation of a production pattern, animation scene information, and the like are stored.
This animation pattern is referred to when displaying the animation of the production pattern, and stores the combination of animation scene information included in the production pattern, the display order of each animation scene information, and the like. The animation scene information stores information such as weight frame (display time), target data (sprite identification number, transfer source address, etc.), parameters (sprite display position, transfer destination address, etc.), drawing method, etc. doing.

The CGROM 154 includes a flash memory, an EEPROM, an EPROM, a mask ROM, and the like. The CGROM 154 compresses and stores image data (sprite, movie) or the like including a collection of pixel information in a predetermined range of pixels (for example, 32 × 32 pixels). ing. The pixel information is composed of color number information for designating a color number for each pixel and an α value indicating the transparency of the image.
Furthermore, the CGROM 154 stores palette data in which color number information for designating color numbers and display color information for actually displaying colors are associated with each other without being compressed.
Note that the CGROM 154 may have a configuration in which only a part of the image data is compressed without being compressed. As a movie compression method, various known compression methods such as MPEG4 can be used.
The CGROM 154 also stores a lot of audio data as will be described later.

  The crystal oscillator 155 outputs a pulse signal to the clock generation circuit 205 of the VDP 200, and divides the pulse signal to synchronize with the system clock for the VDP 200 to control by the clock generation circuit 205 and the image display device 31. A synchronization signal or the like is generated for the purpose.

The VRAM 156 is configured by an SRAM that can write or read image data at high speed.
The VRAM 156 also draws or displays an image, a display list storage area 156a that temporarily stores the display list output from the host CPU 151, a development storage area 156b that stores image data decompressed by the decompression circuit 206, and the like. Therefore, a first frame buffer 156c and a second frame buffer 156d for the main liquid crystal 31a, and a first frame buffer 156e and a second frame buffer 156f for the sub liquid crystal 31b are provided. The VRAM 156 also stores palette data.
The two sets of frame buffers (156c and 156d, 156e and 156f) are alternately switched between a “drawing frame buffer” and a “display frame buffer” every time drawing is started.

The VDP 200 is a so-called image processor, reads image data from one of the frame buffers (display frame buffer) based on an instruction from the host CPU 151, and a video signal (RGB signal or the like) based on the read image data. Is generated and output to the image display device.
However, in the gaming machine of the present embodiment, the VDP 200 is not only an image processor, but has an audio output function.
The VDP 200 includes a control register 201, a CG bus I / F 202, a CPU I / F 203, a clock generation circuit 205, a decompression circuit 206, a drawing circuit 207, a display circuit 208, a memory controller 209, and audio control. And a circuit 300.

The control register 201 is a register for the VDP 200 to control drawing and display, and drawing control and display control are performed by writing and reading data to and from the control register 201. The host CPU 151 can write and read data to and from the control register 201 via the CPU I / F 203.
The control register 201 is a system control register that performs basic settings necessary for the operation of the VDP 200, a data transfer register that performs settings necessary for data transfer, and a drawing that performs settings for controlling drawing. A register, a bus interface register for making settings necessary for bus access, a decompression register for making settings necessary for decompressing a compressed image, a display register for making settings for controlling display, and six types It has a register.

The CG bus I / F 202 is an interface circuit for communication with the CGROM 154, and image data from the CGROM 154 is input to the VDP 200 via the CG bus I / F 202.
The CPU I / F 203 is an interface circuit for communication with the host CPU 151, and the host CPU 151 outputs a display list to the VDP 200, accesses a control register, and various types of information from the VDP 200 via the CPU I / F 203. The host CPU 151 inputs an interrupt signal.

The data transfer circuit 204 performs data transfer between various devices.
Specifically, data transfer between the host CPU 151 and the VRAM 156, data transfer between the CGROM 154 and the VRAM 156, and data transfer between various storage areas (including the frame buffer) of the VRAM 156 are performed.
The clock generation circuit 205 receives a pulse signal from the crystal oscillator 155 and generates a system clock that determines the operation processing speed of the VDP 200. Also, a synchronization signal generation clock is generated, and the synchronization signal is output to the image display device via the display circuit.

The decompression circuit 206 is a circuit for decompressing the image data compressed in the CGROM 154, and stores the decompressed image data in the expanded storage area 153b.
The drawing circuit 207 is a circuit that performs sequence control based on a display list including drawing control commands.

The display circuit 208 generates an RGB signal (analog signal) indicating image color data as a video signal from the image data (digital signal) stored in the “display frame buffer” in the VRAM 156, and generates the generated video signal ( RGB signal) is output to the main liquid crystal 31a and the sub liquid crystal 31b. Further, the display circuit 208 also outputs a synchronizing signal (vertical synchronizing signal, horizontal synchronizing signal, etc.) for synchronizing with the main liquid crystal 31a and the sub liquid crystal 31b to the main liquid crystal 31a and the sub liquid crystal 31b.
In this embodiment, the video signal is output to the RGB signal main liquid crystal 31a and the sub liquid crystal 31b obtained by converting the digital signal into an analog signal. However, the video signal may be output as the digital signal.

The memory controller 209 performs control to switch between the “drawing frame buffer” and the “display frame buffer” when the host CPU 151 instructs to switch the frame buffer.
The sound control circuit 300 reads a predetermined program based on the command transmitted from the effect control board 120 and controls sound output in the sound output device 34.
The voice control circuit 300 outputs voice using the voice data stored in the CGROM 154. In this case, the CGROM 154 includes a sound source ROM for storing audio data.

Note that the audio data is not stored in the CGROM 154, but a sound source ROM may be separately provided in the VDP 200.
In this case, audio data is not stored in the CGROM 154 having a fixed capacity, and more image data can be stored. Therefore, the production using video can be made more colorful and impressive.

Further, the audio control circuit 300 may not be included in the VDP 200 but may be provided independently within the image control board 150. In that case, the sound source ROM may be included in the audio control circuit 300.
The main liquid crystal 31a and the sub liquid crystal 31b are provided with LCD drivers 36a and 36b for driving the liquid crystal, respectively, and control signals from the VDP 200 are input to these LCD drivers.

<Main control board>
Next, various operations executed by the main control board 110 that is the main control board of the pachinko machine 1 according to the present embodiment will be described.
FIG. 5 is an explanatory diagram of various random numbers acquired in the main control board 110 of the pachinko machine 1, where (a) is a special symbol determination random number, (b) is a jackpot symbol determination random number, and (c) is a reach determination. (D) is a diagram showing an example of auxiliary symbol determination random numbers.
On the main control board 110, a special symbol is determined by the special symbol determining random number shown in FIG. 5A and the jackpot symbol determining random number shown in FIG. 5B. Further, the auxiliary symbol is determined by the auxiliary symbol determining random number shown in FIG.

For the special symbol determination random number shown in FIG. 5A, one random number value is acquired from among 300 random numbers from “0” to “299”, for example, at the start opening prize.
In the case of the special symbol determining random number shown in FIG. 5A, in the low probability gaming state (normal gaming state), the jackpot ratio is set to 1/300, and the acquired special symbol determining random number value is “3”. Sometimes a jackpot is determined.
On the other hand, in the high probability gaming state, the jackpot ratio is set to 10/300, for example, 10 times that of the low probability gaming state, and the acquired special symbol determination random numbers are “3”, “7”, “37”. , “67”, “97”, “127”, “157”, “187”, “217”, “247” are determined to be big hits. In addition, in the special symbol determination random number shown in FIG. 5A, a small lottery, which is a type of loss, is also performed. Here, the small hit ratio is set to 3/300, and when the acquired special symbol determining random number values are “150”, “200”, “250”, it is determined that the small hit is.

Next, for the jackpot symbol determination random number shown in FIG. 5B, one random number value is acquired from 250 random numbers from “0” to “249”. Then, based on the acquired jackpot symbol determination random value, any one jackpot is determined from a plurality of jackpots.
In the present embodiment, as a plurality of types of big hits, there are prepared per length with a normal time, short length with a normal time, a long length with a high probability time, a short length with a high probability time, and a short time without a high probability time.
Note that the short-time gaming state refers to a gaming state in which a game ball is more likely to win the second starting port 14 than in the normal gaming state. That is, the second start port opening / closing door 14b of the second start port 14 is changed from a closed state in which a game ball is difficult to win to an open state in which a game ball is easy to win when a predetermined condition described later is satisfied. It means a gaming state with support for opening the second start opening / closing door 14b in which the probability of entering a game ball into the start opening 14 is increased.

The regular short-term long win is a relatively long opening time of the first grand prize winning hole 16 or the second big prize winning hole 17 at the time of the big hit game, and a relatively large amount of payout can be expected. This is a jackpot that gives a short-time game for a period until the special symbol changes a predetermined number of times (for example, 100 times).
In the short win with the normal time, the opening time of the first big winning opening 16 or the second big winning opening 17 at the time of the big hit game is short, and it is not expected to pay out the ball, but after the big hit game, the special symbol is given a predetermined number of times (for example, 100 times) It is a big hit that grants a short-time game for a period until it fluctuates.

The long win with high probability short-time is the longest opening time of the first grand prize winning hole 16 or the second big prize winning hole 17 at the time of the big hit game, and the expectation of paying out the largest number of balls can be expected. It is a jackpot that gives both high-probability games and short-time games.
Short wins with a high probability of shortening the winning time of the jackpot game increased after the end of the jackpot game, although the opening time of the first jackpot 16 or the second prize winning port 17 at the time of the jackpot game is short and the payout of the ball can not be expected A jackpot that grants both high-probability games and short-time games.
High probability short and short wins increased the probability of winning a big hit after the jackpot game, although the opening time of the first big winning opening 16 or the second big winning opening 17 at the time of the big hit game is short and the payout of the ball cannot be expected. A jackpot that grants high-probability games.

Further, in the pachinko machine 1 of the present embodiment, some types of jackpots are selected depending on whether a game ball enters the first start port 13 or a game ball enters the second start port 14. It is comprised so that the ratio to be performed may differ.
For example, the ratio at which the length with the normal time is selected is the same at 35/250 when the game ball wins at the first start port 13 and when the game ball wins at the second start port 14. . Similarly, the ratio at which the short win with the normal time is selected is the same at 15/250 both when the game ball wins the first start port 13 and when the game ball wins the second start port 14. .
Specifically, as shown in FIG. 5B, the jackpot symbol determination random number value acquired when the game ball wins the first start port 13 or the second start port 14 is “0” to “34”. If this is the case, the per unit with the normal time is selected, and if it is “35” to “49”, the normal unit with the short time is selected.

On the other hand, the ratio of the selection of the high probability short-time length and the high probability short-time short distance is different between the case where a game ball wins the first start port 13 and the case where a game ball wins the second start port 14. For example, the ratio at which the high probability time-shortened length is selected is 25/250 when a game ball wins the first start port 13 and 175/250 when a game ball wins the second start port 14. The
In addition, the rate at which the short win with high probability is selected is 75/250 when a game ball wins the first start port 13 and 25/250 when a game ball wins the second start port 14. The
Further, the rate at which the high probability short / short short win is selected is 100/250 only when a game ball wins the first start port 13.
Specifically, if the jackpot symbol determination random number value acquired when the game ball wins the first start port 13 is “50” to “74”, the long-probing long-term per-choice is selected, and “75 ”To“ 149 ”, a short hit with high probability is selected, and“ 150 ”to“ 249 ”is selected as a short hit without high probability.
On the other hand, if the random number for jackpot symbol determination acquired when the game ball wins at the second starting opening is “50” to “224”, the long perk with high probability is selected and “225” is selected. If it is ˜ “249”, a short chance with a short time with high probability is selected.

  Further, the reach determination random number shown in FIG. 5C is obtained by acquiring one random number value from 250 random numbers from “0” to “249” at the time of starting winning, and the acquired reach determination random number value. Is “0” to “21”, “reach is present”, and when the acquired random number for reach determination is “22” to “249”, “reach is not found”.

5D, one random number value is acquired from 10 random numbers “0” to “9” when passing through the gate.
In the low-probability gaming state in which both the short-time flag and the high-accuracy flag are OFF, or in the high-probability short-timeless gaming state in which the short-time flag is OFF and the high-accuracy flag is ON, the acquired auxiliary symbol determination random number value is “7. ""
On the other hand, in the low-probability short-time gaming state in which the short-time flag is ON and the high-accuracy flag is OFF, or in the high-probability short-time gaming state in which both the short-time flag and the high-accuracy flag are ON, the acquired auxiliary symbol determination random number value is When it is “0” to “9”, it is determined to be a hit.

  Next, main processes executed by the main control board 110 of the pachinko machine 1 according to the present embodiment will be described. Note that the processing described below can be realized by the CPU 212 of the main control board 110 executing a program stored in the ROM 213. A description of the random number update process is omitted.

[Timer interrupt processing]
FIG. 6 is a flowchart showing an example of a timer interrupt process executed by the CPU of the main control board.
As the timer interrupt process, the CPU 212 performs random number update process (S10), start port SW process (S20), gate SW process (S30), special symbol process (S40), customer waiting setting process (S50), auxiliary symbol process ( S60), a special winning opening process (S70), a second start opening process (S80) and the like are executed.

Next, various processes executed as the timer interrupt process will be described.
[Start-up SW processing]
FIG. 7 is a flowchart showing an example of the start port SW process executed by the CPU of the main control board.
In this case, in step S101, the CPU 212 determines whether or not the first start port SW13a of the first start port 13 is on. If it is determined that the first start port SW13a is on, step S102 is performed. Then, it is determined whether or not the retained number U1 of the first start port SW13a is smaller than “4”.

If it is determined that the reserved number U1 is smaller than “4”, “1” is added to the reserved number U1 in step S103. Thereafter, in step S104, a special symbol determination random number value, a jackpot symbol determination random value, a reach determination random number value, a variation pattern random number value, and the like for the special symbol are acquired and stored in the RAM 214.
In this embodiment, it is assumed that 180 (0 to 179) fluctuation pattern random number values are prepared.

  Next, in step S105, the CPU 212 increases the number of holds displayed on the first special symbol hold indicator 23 and sets a first hold number increase command. When the first hold number increase command is set, the CPU 212 transmits the first hold number increase command to the effect control board 120. If a negative result is obtained in step S102, that is, if it is determined that the hold number U1 is “4” which is the maximum holdable number, the process of steps S103 to S105 is skipped and the process proceeds to step S106.

Next, in step S106, the CPU 212 determines whether or not the second start port SW14a of the second start port 14 is on. If it is determined that the second start port SW14a is on, step S107 is performed. Then, it is determined whether or not the reserved number U2 of the second start port SW14a is smaller than “4”.
If it is determined that the reserved number U2 is less than “4”, “1” is added to the reserved number U2 in step S108. Thereafter, in step S109, the special symbol determination random number value for the special symbol, the jackpot symbol determination random number value, the reach determination random number value, the variation pattern random number value, and the like are acquired and stored in the RAM 214.

  Next, in step S110, the CPU 212 increases the number of holdings of the second special symbol holding display 24 and sets a second holding number increase command. When the second hold number increase command is set, the CPU 212 transmits the second hold number increase command to the effect control board 120 and ends the start port SW process. If a negative result is obtained in step S107, that is, if it is determined that the reserved number U2 is “4”, which is the maximum allowable number, the start port SW process is terminated.

[Gate SW processing]
FIG. 8 is a flowchart showing an example of the gate SW process executed by the CPU of the main control board.
In step S121, the CPU 212 determines whether or not the gate SW15a of the gate 15 is on. If the CPU 212 determines that the gate SW15a is on, the number of times the gate SW passes through the gate SW15a is “4” in step S122. It is determined whether or not it is less.

If it is determined in step S122 that the number of gate passages G is less than “4”, “1” is added to the number of gate passages G in step S123, and a random number for auxiliary symbol determination is acquired in subsequent step S124. And stored in the RAM 214, and the gate SW processing ends.
If it is determined in step S121 that the gate SW 15a is not turned on, or if a negative result is obtained in step S122, that is, if it is determined that the gate passage count G is “4”, which is the maximum holdable number, The gate SW process ends.

[Special symbol processing]
FIG. 9 is a flowchart showing an example of special symbol processing executed by the CPU of the main control board.
If the CPU 212 determines in step S131 whether the special game flag is ON, that is, whether the game is a big hit game or a small hit game, and determines that it is not a big hit game or a small hit game In the subsequent step S132, it is determined whether or not the special symbol of the first special symbol display device 20 or the second special symbol display device 21 is changing.
If it is determined in step S132 that the special symbol is not fluctuating, then in step S133, it is determined whether or not the retained number U2 of the second starting port SW14a to be preferentially digested is greater than “1”. If it is determined in step S133 that the reserved number U2 is greater than “1”, the reserved number U2 is decremented by “1” in step S134.

  On the other hand, if it is determined in step S133 that the reserved number U2 is not ≧ 1, that is, if the reserved number U2 is “0”, then in step S135, the reserved number U1 of the first start port SW13a is “1”. It is determined whether or not there is more, and if it is determined in step S135 that the reserved number U1 is greater than “1”, “1” is subtracted from the reserved number U1 in the subsequent step S136.

Next, in step S137, the CPU 212 turns OFF if the customer waiting flag is ON, and then executes a special game determination process (FIG. 11) described later in step S138. After execution of the special game determination process in step S138, a variation pattern selection process (FIG. 12) described later is executed in step S139. After execution of the variation pattern selection process in step S139, the variation of the corresponding first special symbol display device 20 or second special symbol display device 21 is started in step S140, and in step S141, the effect control board 120 is started. Set the variable start command to be sent to.
The variation start command includes a variation pattern command indicating the variation time of the special symbol, a jackpot or small hit command indicating the lottery result of the jackpot lottery, a jackpot symbol command indicating the lottery result of the jackpot symbol, and a reach indicating the lottery result of the reach lottery Commands, gaming state commands related to the current gaming state, and the like are included.

Next, in step S142, the CPU 212 determines whether or not the variation time of the first or second special symbol has passed a predetermined variation time.
If it is determined in step S142 that the predetermined variation time has elapsed, in the subsequent step S143, the variation of the first special symbol display device 20 or the second special symbol display device 21 is stopped and the predetermined special symbol is displayed.
Thereafter, in step S144, a variable stop command is set, and in the subsequent step S145, a stop process (FIG. 14) described later is executed to end the special symbol process.

If it is determined in step S131 that the special game flag is ON, or if it is determined in step S142 that the variation time of the special symbol has not reached the predetermined variation time, the special symbol processing is terminated.
If it is determined in step S132 that the special symbol is changing, the process proceeds to step S142, and it is determined whether or not the variation time of the special symbol has passed a predetermined variation time.
If it is determined in step S135 that the hold number U1 is not ≧ 1, that is, if it is determined that there is no hold of the hold numbers U1 and U2, in step S146, execution is performed for the customer waiting setting process shown in FIG. The special symbol process ends.

[Customer waiting setting process]
FIG. 10 is a flowchart showing an example of a customer waiting setting process executed by the CPU of the main control board.
In step S151, the CPU 212 determines whether or not the customer waiting flag is ON. If the CPU 212 determines that the customer waiting flag is ON, the customer waiting setting process ends.
On the other hand, if it is determined in step S151 that the customer waiting flag is not ON, a customer waiting command is set in step S152, and in step S153, the customer waiting flag is turned on and the customer waiting setting process is terminated.
It should be noted that the customer waiting flag is turned from OFF to ON when a state where there is no special symbol hold and no special symbol is held for a predetermined period.

[Special game determination process]
FIG. 11 is a flowchart showing an example of the special game determination process executed by the CPU of the main control board.
In step S161, the CPU 212 determines the special symbol determination random number value stored in the RAM 214, and in the subsequent step S162, determines whether or not the jackpot is won.
When it is determined in step S162 that the jackpot is won, in the subsequent step S163, the jackpot symbol determination random number value stored in the RAM 214 is determined, and in step S164, the first special symbol is determined based on the determination result. The jackpot symbol to be displayed on the display device 20 or the second special symbol display device 21 is set, and the special game determination process is terminated.

On the other hand, if it is determined in step S162 that the jackpot has not been won, in step S165, it is determined whether or not the jackpot has been won based on the special symbol determination random number value.
In step S165, if it is determined that the small win is won, in the subsequent step S166, the small special symbol displayed on the first special symbol display device 20 or the second special symbol display device 21 is set, and the special game determination process is performed. Exit.
Also, if it is determined in step S165 that the winning combination is not won, in step S167, a lost symbol to be displayed on the first special symbol display device 20 or the second special symbol display device 21 is set and special game determination processing is performed. Exit.

[Variation pattern selection processing]
FIG. 12 is a flowchart showing an example of the variation pattern selection process executed by the CPU of the main control board.
First, in step S171, the CPU 212 determines whether or not the time reduction flag indicating the time saving gaming state is ON. If it is determined in step S171 that the short time flag is ON, in the subsequent step S172, the short time gaming state table is set as the variation pattern table, and the process proceeds to step S174.

On the other hand, if it is determined in step S171 that the short time flag is not ON, in step S173, the non-short time gaming state table is set as the variation pattern table and the process proceeds to step S174.
Next, in step S174, the CPU 212 determines the previously obtained variation pattern random value, and in the subsequent step S175, sets the variation pattern based on the set variation pattern table and variation pattern random value. Then, the variation pattern selection process ends.

  FIG. 13 is a diagram showing an example of a variation pattern table, where (a) shows a variation pattern table for non-short game state, and (b) shows an example of a variation pattern table for time-short game state.

First, the non-time-saving gaming state variation pattern table shown in FIG.
In the variation pattern table for non-time-saving gaming state shown in FIG. 13A, when the random number value for special symbol determination is a big hit of “3” and the variation pattern random number value is “0 to 89”, the variation time is A fluctuation pattern 1 as long as 90 seconds is selected. When the variation pattern 1 is selected, a winning effect with reach A is performed.

When the special symbol determination random number is a big hit of “3” and the variation pattern random value is “90 to 179”, the variation pattern 2 having a variation time of 60 seconds is selected. When the variation pattern 2 is selected, a winning effect with reach B is performed.
When the special symbol determination random number value is “150, 200, 250”, the variation pattern 3 having a variation time of 60 seconds is used regardless of the variation pattern random number value “0 to 179” selected. select. When the variation pattern 3 is selected, a chance effect is performed.

Next, a case where the special symbol determination random number value is a loss other than “3, 150, 200, 250” and the gaming state is the non-short-time gaming state will be described.
When the special symbol determination random number value is lost, the variation pattern is determined based on the number of reserved balls, the reach determination random number value, the variation pattern random number value, and the like of the first special symbol.
Specifically, when the total number of reserved balls of the first and second special symbols is “0 to 2” and the reach determination random number value is “22 to 249” and there is no reach, the selected variation pattern Regardless of the random value “0 to 179”, the variation pattern 4 in which the variation time is 12 seconds is selected. When the variation pattern 4 is selected, the effect of the normal variation A is performed.

On the other hand, the total number of reserved balls of the first and second special symbols is “0 to 2”, the reach determination random number value is “0 to 21”, and the variation pattern random number value is “0 to 29”. In this case, the variation pattern 5 having a variation time of 90 seconds is selected. When the variation pattern 5 is selected, a loss effect with reach A is performed.

In this case, the variation pattern 6 having a variation time of 30 seconds is selected. When the variation pattern 6 is selected, a loss effect with reach B is performed.

Next, when the total number of reserved balls of the first and second special symbols is “3” and the reach determination random number value is “22 to 249” and there is no reach, the selected variation pattern random value “0” is selected. Regardless of “˜179”, the variation pattern 7 in which the variation time is 8 seconds is selected. When the variation pattern 7 is selected, an effect of normal variation B is performed.
In addition, when the total number of reserved balls of the first and second special symbols is “3”, the reach determination random number value is “0 to 21”, and the variation pattern random number value is “0 to 29” The variation pattern 5 in which the variation time is 90 seconds is selected.

When the total number of reserved balls of the first and second special symbols is “4 to 8” and the reach determination random number value is “22 to 249” and there is no reach, the selected variation pattern random value “ Regardless of “0 to 179”, the variation pattern 8 having a variation time of 4 seconds is selected. When the variation pattern 8 is selected, the effect of the shortened variation A is performed.
The total number of reserved balls of the first and second special symbols is “4 to 8”, the reach determination random number value is “0 to 21”, and the variation pattern random number value is “0 to 29”. In this case, the variation pattern 5 in which the variation time is 90 seconds is selected.
Further, the total number of reserved balls of the first and second special symbols is “4 to 8”, the reach determination random number value is “0 to 21”, and the variation pattern random number value is “30 to 179”. In this case, the variation pattern 6 in which the variation time is 30 seconds is selected.

  Next, the short time gaming state variation pattern table shown in FIG. 13B will be described. Note that the short-time gaming state variation pattern table shown in FIG. 13B is the same as the non-short-time gaming state variation pattern table shown in FIG. Therefore, the description is omitted, and only the case where the special symbol determination random number value is lost and the gaming state is the short-time gaming state will be described here.

If the special symbol determination random number value is lost, the variation pattern is determined based on the number of reserved balls of the second special symbol, the reach determination random number value, the variation pattern random value, and the like.
Specifically, when the total number of reserved balls of the first and second special symbols is “0 to 5” and the reach determination random number value is “22 to 249” and there is no reach, the selected variation pattern Regardless of the random value “0 to 179”, the variation pattern 4 in which the variation time is 12 seconds is selected.

In this case, the variation pattern 6 having a variation time of 30 seconds is selected. When the variation pattern 6 is selected, a loss effect with reach B is performed.

On the other hand, if the total number of reserved balls of the first and second special symbols is “6 to 8” and the reach determination random number value is “22 to 249” and there is no reach, the selected variation pattern random value “ Regardless of “0 to 179”, the variation pattern 9 having a variation time of 2 seconds is selected. When the variation pattern 9 is selected, the effect of the shortened variation B is performed.
The total number of reserved balls of the first and second special symbols is “6 to 8”, the reach determination random number value is “0 to 21”, and the fluctuation pattern random number value is “0 to 29”. In this case, the variation pattern 5 is selected.
In addition, the total number of reserved balls of the first and second special symbols is “6 to 8”, the reach determination random number value is “0 to 21”, and the variation pattern random number value is “30 to 179”. In this case, the variation pattern 6 is selected.

  In this embodiment, the variation pattern is determined based on the special symbol determination random number value and the variation pattern random value when the jackpot is won, but this is only an example, and the special symbol determination random value And a variation pattern may be determined based on a special symbol determination random value, a jackpot symbol determination random value, and a variation pattern random value.

[Processing while stopped]
FIG. 14 is a flowchart illustrating an example of a stop process executed by the CPU of the main control board.
In step S181, the CPU 212 determines whether or not the time reduction flag is ON. If it is determined that the time reduction flag is ON, the remaining number of short time games stored in the RAM 214 in the subsequent step S182. Subtract “1” from J.

Next, in step S183, the CPU 212 determines whether or not the remaining game count J is “0”. If the remaining game count J is “0”, the special symbol variation display is predetermined in the short-time game. This means that the number of times (for example, 100 times) has been performed, and therefore, in the subsequent step S184, the time reduction flag is turned OFF.
If it is determined in step S181 that the time reduction flag is not ON, or if it is determined in step S183 that the remaining game number J is not “0”, the process proceeds to step S185.

Next, in step S185, the CPU 212 determines whether or not the high-accuracy flag is ON. If it is determined that the high-accuracy flag is ON, it is stored in the RAM 214 in the subsequent step S186. “1” is subtracted from the remaining game count X of the high probability game.
Next, in step S187, the CPU 212 determines whether or not the remaining game count X is “0”. If the remaining game count X is “0”, the special symbol variation display is performed in the high-probability game. This means that it has been performed a predetermined number of times (for example, 10,000 times), so in the subsequent step S188, the high-accuracy flag is turned OFF.
If it is determined in step S185 that the high-accuracy flag is not ON, or if it is determined in step S187 that the remaining game count X is not “0”, the process proceeds to step S189.

  Next, in step S189, the CPU 212 determines whether or not it is a big win based on the special symbol set in the first special symbol display device 20 or the second special symbol display device 21, and if it is determined that it is not a big hit Next, in step S190, it is determined whether or not the set special symbol is “small hit”. If it is determined that the game is a small hit, the small hit game flag is turned ON in step S191. Thereafter, in step S192, the jackpot opening is started, and in step S193, the jackpot opening command is set, and the stopping process is ended.

On the other hand, if it is determined in step S190 that it is not a small hit, the variable stop process is terminated without turning on the small hit game flag.
If it is determined that the jackpot is a big hit in step S189, it is next determined in step S194 whether the jackpot is a long hit. If it is determined that the jackpot is a big hit, the long hit is determined in step S195. The winning game flag (special game flag) is set to ON. Otherwise, the short winning game flag (special game flag) is set to ON in step S196. Thereafter, in step S197, the remaining number J of short-time games and the remaining number X of high-probability games are set to “0”, respectively, and the remaining game number J / X is reset. Then, the high-accuracy flag is turned OFF and the process proceeds to step S192.

[Auxiliary symbol processing]
FIG. 15 is a flowchart showing an example of auxiliary symbol processing executed by the CPU of the main control board.
In step S201, the CPU 212 determines whether or not the auxiliary game flag is ON. If the CPU 212 determines that the auxiliary game flag is ON, the auxiliary symbol process ends.
On the other hand, if it is determined in step S201 that the auxiliary game flag is not ON, it is determined in step S202 whether or not the auxiliary symbol is changing. If it is determined in step S202 that the auxiliary symbol is not changing, it is determined in step S203 whether or not the gate passing number G that stores the number of times that the game ball has passed through the gate SW15a is greater than "1". When the number of gate passages G is greater than “1”, in the subsequent step S204, “1” is subtracted from the number of gate passages G and it is determined that the number of gate passages G is not greater than “1”, that is, “0”. If so, the auxiliary symbol processing is terminated.

Next, the CPU 212 determines an auxiliary symbol determination random number value in step S205, sets a stop symbol to be stopped and displayed on the auxiliary symbol display device 22 in subsequent step S206, and sets a variation time in step S207. .
Here, it is conceivable that the variation time of the auxiliary symbol is set to, for example, 4.0 seconds if the hour / hour flag is OFF, and to 1.5 seconds if the hour / hour flag is ON.

Next, in step S209, the CPU 212 determines whether or not the variation time of the auxiliary symbol has elapsed, and if it is determined that the predetermined variation time has elapsed, the CPU 212 stops the variation in step S210. On the other hand, when it is determined in step S209 that the variation time of the auxiliary symbol has not elapsed, the auxiliary symbol processing is terminated.
Next, in step S211, the CPU 212 determines whether or not the auxiliary symbol is a winning symbol. If the auxiliary symbol is a winning symbol, in step S212, the auxiliary game flag is set to ON and auxiliary symbol processing is performed. Exit.
If it is determined in step S211 that the stopped symbol is not a winning symbol, the auxiliary symbol process is terminated without turning on the auxiliary game flag.
If it is determined in step S202 that the auxiliary symbol is changing, the process proceeds to step S209, where it is determined whether or not the variation time of the auxiliary symbol has passed a predetermined variation time.

[Large winning prize processing]
FIG. 16 is a flowchart showing an example of the big prize opening process executed by the CPU of the main control board.
In step S221, the CPU 212 determines whether or not the small hit game flag or the special game flag is ON. If it is determined that the small hit game flag or the special game flag is ON, the opening is performed in step S222. It is determined whether it is in the middle. If it is determined in step S222 that the jackpot opening is in progress, then in step S223, it is determined whether or not the opening time has elapsed. If it is determined in step S223 that the opening time has elapsed, then in step S224, “0” is set to the value of the number of rounds R, and the number of rounds (number of Rs) / operation pattern is set.

FIG. 17 is a diagram showing a setting example of the number of rounds / operation pattern. For example, when the special game is per length with a normal time, the number of rounds (R number) is set to 4R, and the operation pattern in 1R is 29. Set 5 seconds open x 1 time. When the big hit is a short hit with a normal time, the number of rounds (R number) is set to 2R, 1R, and the operation pattern during 0.1R is set to 0.1 second open × 1. Furthermore, if the jackpot is per length with a high probability, the number of rounds (number of R) is set to 16R, 1R operating pattern in 29.5 seconds open × 1 time, the jackpot is a short per short with a high probability When the high probability is short and short, the number of rounds (R number) is set to 2R and 1R, and the operation pattern in 1R is set to 0.1 second open × 1.
In the case of a small hit, for example, the number of rounds (R number) is set to 1R, 1R, and the operation pattern in 1R is set to 0.1 second open × 2 times.

  Next, in step S225, the CPU 212 sets “0” in the number counter C indicating the number of winnings per round to the first big winning opening 16 or the second big winning opening 17, and in subsequent step S226, “1” is added to the value of the number of rounds R. In the subsequent step S227, the operation of the first big prize opening 16 or the second big prize opening 17 is started. That is, either the first grand prize winning opening 16 or the second big winning prize opening 17 is changed from the closed state to the open state.

Next, in step S228, the CPU 212 determines whether or not the operation time of the first big prize opening 16 or the second big prize opening 17 has passed a predetermined time, and the operation time has not passed the predetermined time. In the subsequent step S229, it is determined whether or not the value of the number counter C has reached the specified number.
If it is determined in step S229 that the value of the number counter C is the specified number C, the operation of the first big prize opening 16 or the second big prize opening 17 is ended in step S230. That is, the first grand prize winning port 16 or the second grand prize winning port 17 in the open state is closed.

On the other hand, when it is determined that the value of the number counter C has not reached the specified number, the big prize opening process is terminated.
In step S228, if the operation time of the first big prize opening 16 or the second big prize opening 17 has exceeded the predetermined operation time, the process of step S229 is skipped and the number of the number counter C is set. Without checking, the operation of the first big prize opening 16 or the second big prize opening 17 is finished in step S230.

Next, in step S231, the CPU 212 determines whether or not the jackpot round number is the maximum round number R. That is, it is determined whether or not the jackpot round is the final round.
If it is determined in step S231 that the jackpot round is the final round, ending is started in step S232, and an ending command is set in step S233.

  Next, in step S234, the CPU 212 sets the value of the number of rounds R to “0”. Thereafter, in step S235, it is determined whether or not the ending time has passed. If it is determined that the ending time has passed, a game state setting process described later is executed in step S236. Thereafter, in step S237, the special game flag is turned OFF, and the big prize opening process is ended.

  If it is determined in step S222 that the jackpot is not opening, it is determined in step S238 whether or not ending is in progress. If it is determined that ending is in progress, the process proceeds to step S235 and ending is in progress. If it is determined that it is not, it is determined in step S239 whether or not the special winning opening is in operation.

If it is determined in step S239 that the first grand prize winning port 16 or the second grand prize winning port 17 is in operation, the process proceeds to step S228, and the first grand prize winning port 16 or the second grand prize winning port 17 is in operation. If it is determined that it is not, the process proceeds to step S225.
If it is determined in step S221 that the opening time has not elapsed, the special winning opening process is terminated. Similarly, if it is determined in step S229 that the value of the number counter C has not reached the specified number, if it is determined in step S231 that the big hit round is not the final round, or the ending time has elapsed in step S235. Even if it is determined that there is not, the special winning a prize mouth process is terminated.

[Game state setting process]
FIG. 18 is a flowchart showing an example of the game state setting process executed by the CPU of the main control board.
First, in step S241, the CPU 212 determines whether or not it is a small hit, and if it is determined that it is a small hit, the gaming state setting process is terminated.
On the other hand, if it is determined in step S241 that it is not a small hit, then in step S242, it is determined whether or not it is a normal hit (per length with normal time or short per hour with normal time). In step S243, the time-shortage flag is set to ON, and in step S244, for example, “100” is set to the remaining game count J of the time-shortage game, and the gaming state setting process is terminated.

  If it is determined in step S242 that it is not a normal hit, it is a big hit for giving a high-probability game. For example, “10000” is set in X.

  Next, in step S247, the CPU 212 determines whether or not the hit is with a time reduction. If it is determined that the hit is with a time reduction, in step S248, the CPU 212 sets the time reduction flag to ON, and in step S249. Then, for example, “10000” is set in the remaining game count J of the short-time game, and the gaming state setting process is terminated. On the other hand, if it is determined in step S247 that the time is not short, the time flag is turned OFF in step S250, and the remaining game count J of the time-saving game is reset in step S251 and the gaming state setting process is terminated. .

[Second start opening process]
FIG. 19 is a flowchart showing an example of the second start port opening process executed by the CPU of the main control board.
In step S261, the CPU 212 determines whether or not the auxiliary game flag is ON. If the CPU 212 determines that the auxiliary game flag is ON, then in step S262, the second start opening / closing door 14b is activated. It is determined whether it is in the middle. In step S262, if the second start port opening / closing door 14b is not in operation (opening), the operation pattern of the second start port opening / closing door 14b is set according to the gaming state in step S263, and in step S264, (2) The operation of the start opening / closing door 14b is started.
Here, the operation pattern (time) of the second start opening / closing door 14b to be set is, for example, 0.15 second opening × 1 if the hour flag is OFF, and 1.80 seconds if the hour flag is ON. It is conceivable to set the opening to 3 times.

Next, in step S265, the CPU 212 determines whether or not the operation time of the second start opening / closing door 14b has elapsed a predetermined time, and if it is determined that the predetermined operation time has elapsed, step S266. Then, the auxiliary game flag is turned OFF, and the second start opening process is terminated.
If it is determined in step S262 that the second start-opening door 14b is operating, the process proceeds to step S265.
If it is determined in step S261 that the auxiliary game flag is not ON, or if it is determined in step S265 that the operation time of the second start port 14 has not elapsed, the second start port opening process is terminated. .

  As described above, in the pachinko machine 1 according to the present embodiment, for example, when the fluctuation of the special symbol displayed on the first special symbol display device 20 or the second special symbol display device 21 is stopped, When a game ball enters, a special symbol determination random number value, a jackpot symbol determination random number value, a reach determination random number value, and the like are obtained by lottery, and the first special symbol display device 20 first Display special symbols in a variable manner. And when it determines with the acquired random number value for special symbol determination having won the special game, the 1st special symbol of the 1st special symbol display apparatus 20 is stopped by a specific symbol. Thereafter, the special game of long hit, short hit or small hit is executed.

During the long hitting game, it is possible to obtain the outgoing ball by firing the game ball aiming at the first big winning port 16 or the second big winning port 17 which is in an open state.
On the other hand, during a short hit game, since the opening time of the grand prize opening is extremely short, even if the game ball is launched aiming at the first big prize opening 16 or the second big prize opening 17, it is possible to obtain almost all the balls. I can't do it.

Similarly, for example, when a game ball enters the second start port 14 when the variation of the special symbol displayed on the first special symbol display device 20 or the second special symbol display device 21 is stopped, The special symbol determination random number value, the jackpot symbol determination random number value, the reach determination random number value, and the like are obtained by lottery in response to the ball, and the second special symbol display device 21 displays the second special symbol in a variable manner.
And when it determines with the acquired random number for special symbol determination having won the special game, the 2nd special symbol of the 2nd special symbol display apparatus 21 is stopped by a specific symbol. Thereafter, the special game of either the big hit (long hit or short hit) or the small hit is executed. During a long hit game, it is possible to obtain an outgoing ball by firing a game ball aiming at the first grand prize winning port 16 or the second big prize winning port 17 which is in an open state for a predetermined period. On the other hand, as described above, during the short hit game, since the opening time of the grand prize opening is extremely short, even if the game ball is launched aiming at the first big prize opening 16 or the second big prize opening 17, it almost gets out You can't do that.

After the jackpot game is over, based on the lottery result of the jackpot symbol determination random number value, as a bonus game, a short-time game in which a short-time game with opening support for the second start opening / closing door 14b is performed for a predetermined period, the short-time game and the jackpot Either a high-probability short-time game (so-called probability variation game) in which a high-probability game with a high probability of winning is a predetermined period or a high-probability short-time game (so-called latent probability variation game) in which only a high-probability game is performed for a predetermined period Transition to the game state.
The high-probability game is continuously performed until the number of fluctuations of the special symbol reaches a preset number of times (for example, 10,000 times) or wins a jackpot again.

On the other hand, the short-time game continues until the number of changes in the special symbol reaches a preset number of times (for example, 100 times for normal short-time games and 10000 times for high-probability short-time games) or until a big win is won again. Done.
Also, during the short-time game, the variation time from the start of change of the special symbol to the stop of the variation is set to be shorter than that during normal game, and the winning probability of the auxiliary symbol is set to be higher than during normal game.
Further, the opening time of the second start opening / closing door 14b at the time of winning the auxiliary symbol is set longer than that during the normal game.
Therefore, during the short-time game, the winning rate of the game ball to the second start port 14 is higher than that during the normal game, so that the player can aim the second start port 14 and launch the game ball during the normal game. Compared to this, the game efficiency can be greatly increased.

  Further, in the pachinko machine 1 according to the present embodiment, when the game ball enters the second start port 14, the winning percentage that is advantageous to the player is greater than when the game ball enters the first start port 13. Therefore, during the short-time game, it is easier to win a jackpot advantageous to the player than during the normal game.

Next, processing executed by the effect control board 120 will be described.
[Timer interrupt processing]
FIG. 20 is a flowchart illustrating an example of timer interrupt processing executed by the CPU of the effect control board. Note that the timer interrupt process shown in FIG. 20 can be realized by the sub CPU 121 of the effect control board 120 executing a program stored in the ROM 223.

Next, in step S403, the sub CPU 121 determines whether or not a variation start command has been received. If it is determined that a variation start command has been received, the sub CPU 121 executes an effect selection process in the subsequent step S404.
The effect selection process in step S404 is a process of selecting an effect to be performed while the special symbol is changing.
If it is determined in step S403 that the change start command has not been received, the process proceeds to step S405 without performing the effect selection process.

Next, in step S405, the sub CPU 121 determines whether or not a variable stop command has been received. If it is determined that a variable stop command has been received, the sub CPU 121 executes a variable effect end process in subsequent step S406. .
Examples of the processing during the end of the variation effect include analysis of the variation stop command, various processing such as a mode flag change based on the analysis result, processing for setting the variation effect end command, and the like.
If it is determined in step S405 that the change stop command has not been received, the process proceeds to step S407 without executing the changing effect end process.

Next, in step S407, the sub CPU 121 determines whether or not an opening command has been received. If it is determined that the opening command has been received, the sub CPU 121 executes special game effect selection processing in a subsequent step S408.
Examples of the special game effect selection processing include opening command analysis, special game effect pattern selection processing, and processing for setting an opening effect start command.
If it is determined in step S407 that the opening command has not been received, the process proceeds to step S409 without executing the special game effect selection process.

Next, in step S409, the sub CPU 121 determines whether or not an ending command for executing an ending effect selection process has been received. If it is determined that the ending command has been received, the sub CPU 121 selects an ending effect in the subsequent step S410. Execute the process.
Examples of the ending effect selection process include analysis of an ending command, ending effect pattern selection, and a process of setting an ending effect start command.

If it is determined in step S409 that an ending command has not been received, the process proceeds to step S411 without executing the ending effect selection process.
Next, in step S411, the sub CPU 121 executes a customer waiting command reception process and ends the command reception process.

[Direction selection process]
FIG. 22 is a flowchart showing an example of the effect selection process executed by the CPU of the effect control board.
In this case, first, the sub CPU 121 analyzes the change start command in step S421, and subtracts the number of held balls stored in the RAM 224 in the subsequent step S422.
Next, in step S423, a variation effect pattern is selected based on the analysis result of the variation start command. In subsequent step S424, a variation effect start command is set, and the effect selection process is terminated.

[Processing during variation production]
FIG. 23 is a flowchart showing an example of the process during the end of the changing effect executed by the CPU of the effect control board.
In this case, the sub CPU 121 analyzes the change stop command in step S431, performs various processes such as changing the mode flag based on the analysis result, and then sets a change effect end command in the next step S432. Then, the process during the end of the variation effect is finished.

[Opening effect selection processing]
FIG. 24 is a flowchart showing an example of the hit effect selection process executed by the CPU of the effect control board.
In this case, the sub CPU 121 analyzes the opening command in step S441, and performs a winning effect pattern selection process in subsequent step S442. Thereafter, in step S443, an opening effect start command is set, and the opening effect selection process ends.

[Ending effect selection processing]
FIG. 25 is a flowchart showing an example of an ending effect selection process executed by the CPU of the effect control board.
In this case, the sub CPU 121 analyzes the ending command in step S451, and performs ending effect pattern selection in the subsequent step S452. Thereafter, in step S453, an ending effect start command is set, and the ending effect selection process is terminated.

Hereinafter, a characteristic configuration of the gaming machine of the present embodiment will be described.
Prior to the description of the configuration of the present embodiment, a basic mechanism for displaying an image (video) on an image display device (liquid crystal screen) of a gaming machine will be outlined.
FIG. 26 is a diagram illustrating a basic configuration of a liquid crystal screen.
The liquid crystal screen is composed of a large number of pixels arranged in a matrix as is well known, and one line of scanning lines (horizontal lines) is composed of pixels arranged in the horizontal direction.
Then, according to the (VGA) input signal, scanning lines (horizontal lines) are scanned one line at a time (for example, from left to right) and vertically (vertically) (pixels are driven) to display an image. Is done.
In the liquid crystal screen, a non-display area (= blank area) in the horizontal direction and the vertical direction can be set around a display area (effective pixel area) 50 including effective pixels on which an image is actually displayed.

In the example shown in FIG. 26A, the blank area set in the horizontal direction and the vertical direction of the effective pixel area 50 includes a horizontal front porch 51, a horizontal back porch 52, a vertical front porch 53, and a vertical back porch 54.
The position of the display area (effective pixel area) 50 in the liquid crystal screen can be changed by adjusting the sizes of the back porch and the front porch.
A blank area set above the effective pixel area 50 is a vertical front porch 53, and a blank area set below the effective pixel area 50 is a vertical back porch 54.
In the horizontal line including the effective pixel area 50, the blank area set on the left side (scanning start side) is the horizontal front porch 51, and the blank area on the right side (scanning end side) is the horizontal back porch 52.
The blank area does not necessarily have to be set separately above, below, and before and after the effective pixel area 50. As shown in FIG. 26B, a horizontal blank area 55 is provided on the front side or the rear side of the effective pixel area 50. May be set as a vertical blank area 56 on the upper side or the lower side.

As described above, the image display device (liquid crystal screen) includes the LCD driver that drives the pixels (liquid crystal) based on a signal input from the VDP 200.
The main liquid crystal 31a includes a driver 36a, and the sub liquid crystal 31b includes a driver 36b.
The liquid crystal screen has different operation modes (driving modes) according to the mode of signals input from the VDP 200 to the LCD driver, and is roughly divided into a DE mode and a fixed mode.
In FIG. 4, it has been described that the video signal and the synchronization signal are output from the display circuit 208. However, this is a signal in a fixed mode, which will be described later, and a data enable signal (DE signal) is used in the DE mode.

(DE mode)
Signals input from the VDP 200 mainly include a drive clock, a luminance signal based on video, a color signal (video signal), and a data enable (DATA_ENABLE, DE) signal.
FIG. 27 is a diagram showing a data enable signal used in the DE mode.
In FIG. 27, only the vertical synchronization period is shown, but in the horizontal synchronization period in which one (horizontal) line is scanned, the LCD driver displays each pixel ( Display (drive) for dot).
The pixels to be displayed constitute the effective pixel area 50.
A drive clock is input corresponding to all the pixels on the liquid crystal screen, but the driver does not display (drive) the corresponding pixels during a period in which the DE signal is invalid (t2 = horizontal blanking period).
As a result, a blank area (horizontal front porch 51 + horizontal back porch 52 or horizontal blank area 55) is formed in the screen.
When the DE signal becomes valid again after the invalid period (t2) of the DE signal continues for a certain period, the driver scans the effective pixel area of the next line.
Thus, since horizontal synchronization can be performed based on the length of the invalid period (t2) of the DE signal, a synchronization signal (H-SYNC signal) in the fixed mode described below is not necessary.
The DE mode is an operation mode in which display control can be performed by valid / invalidity of the DE signal without depending on the H-SYNC signal and a V-SYNC signal described later.

Further, as described above, a blank area (vertical front porch 53 + vertical back porch 54 or vertical blank area 56) is set before and after the effective pixel area 50 even in the vertical synchronization period.
If the invalid period continues for a longer period than the invalid period (t2) of the DE signal in the horizontal synchronization period after the DE signal becomes invalid, it is a vertical blanking period.
When a certain period (t3) elapses from the start of the vertical blanking period, the vertical back porch period corresponding to the vertical back porch 54 ends, and a vertical front porch period corresponding to the vertical front porch 53 for the next screen is reached.
On the liquid crystal screen, screen refresh (display update) is performed at a predetermined vertical synchronization timing. In the case of FIG. 27, the end point of the vertical back porch period is the screen refresh timing (display update time).
When a certain period of time elapses (t4), the vertical front porch period ends, the DE signal becomes valid again, and the LCD driver starts driving the pixels based on the drive clock.
As shown in FIG. 26 (b), when the blank area is collectively set before or after the effective pixel area, the DE signal is output after the invalid period of the DE signal continues for a certain period (t3 + t4). When becomes effective again, the effective pixel driving is started from the first line of the next screen at the screen refresh timing.
As shown in FIG. 26 (a), even when the blank area is set in the effective pixel area separately in the up / down and front / back direction, if attention is paid to the timing at which the DE signal becomes valid, the front porch period and the back porch period are distinguished. is not a problem.

(Fixed mode / HV mode)
In the fixed mode, the input signal input from the VDP 200 mainly includes a drive clock, a luminance signal and a color signal (video signal) based on video, and a synchronization signal (H-SYNC signal, V-SYNC signal, blank signal). including.
FIG. 28 is a diagram illustrating a synchronization signal used in the fixed mode.
When the V-SYNC signal is input from the VDP 200, the driver scans (drives) line by line from the first dot on the liquid crystal screen according to the state of the V-BLANK signal.
A period during which the V-BLANK signal is invalid after the V-SYNC signal is input corresponds to the vertical blank area 56 (vertical front porch 53 + vertical back porch 54).
In the effective period of the V-BLANK signal, drawing on the effective pixel region 50 is performed.
The invalid period of the H-BLANK signal (not shown) during the valid period of the V-BLANK signal corresponds to the horizontal blank area 55 (horizontal front porch 51 + horizontal back porch 52). When the H-BLANK signal is valid, actual drawing (driving of pixels) is performed using effective pixels.
When the H-SYNC signal is input during scanning of one line, the next line is scanned.
When the V-SYNC signal is input after the vertical back porch period, the next screen scan is started at the screen refresh timing.

Compared with the case of the DE mode shown in FIG. 27, the signal widths of the H-SYNC (horizontal synchronization) signal and the V-SYNC (vertical synchronization) signal are added to the horizontal blanking period and the vertical blanking period, respectively.
The vertical blanking period (vertical front porch period + vertical back porch period) is defined by the V-BLANK signal.
As shown in FIG. 26 (b), when the blank area is collectively set before or after the effective pixel area, at the end of the blanking period in which the vertical front porch 53 and the vertical back porch 54 are combined. The V-SYNC signal is input to return to the first pixel of the next screen.
This timing is the screen refresh timing.

FIG. 29 is a diagram illustrating a problem that occurs when a plurality of image display devices are provided.
As described above, the gaming machine of this embodiment includes a plurality of liquid crystal screens (main liquid crystal 31a and sub liquid crystal 31b).
The sub liquid crystal 31b differs from the main liquid crystal 31a in specifications such as the number of pixels and the refresh rate (Hz) (display update cycle).
29A shows the configuration of the main liquid crystal 31a, and FIG. 29B shows the configuration of the sub liquid crystal 31b.
Note that FIG. 29 illustrates a conceptual pixel configuration, and details such as the number of pixels do not necessarily match those of an actual image display device and the following description.
The main liquid crystal 31a includes an effective pixel area 50a, a horizontal front porch 51a, a horizontal back porch 52a, a vertical front porch 53a, and a vertical back porch 54a. The sub liquid crystal 31b includes an effective pixel area 50b, a horizontal front porch 51b, a horizontal Assume that a back pouch 52b, a vertical front pouch 53b, and a vertical back pouch 54b are provided.

In FIG. 29A, the number of effective pixels (effective pixel area 50a) of the main liquid crystal 31a is 1,280 (H) × 1,024 (V). When the blank area is included, the entire screen is 1,632 ( H) × 1,102 (V) dots (clock).
As described above, since the drive clock corresponds to all the pixels constituting the liquid crystal screen, in this case, the total drive number of the main liquid crystal 31a is 1,632 × 1,102 = 1,798,464.
When the drive clock frequency of the main liquid crystal 31a is 108 MHz, the refresh rate (drive clock frequency / total number of drives = number of screens that can be drawn per second) is 60.05124373 Hz.
It can be said that a drive clock frequency of 108 MHz is necessary to operate a liquid of 1,632 × 1,102 dots at about 60 Hz.

In FIG. 29B, the number of effective pixels (effective pixel region 50b) of the sub liquid crystal 31b is 862 (H) × 260 (V), and when the blank region is included, the entire screen is 1,056 (H) × 394. (V).
In this case, the total drive number of the sub liquid crystal 31b is 1,056 × 394 = 416,064.
When the drive clock frequency of the sub liquid crystal 31b is 25 MHz, the refresh rate is 60.08691 Hz.
It can be said that a drive clock frequency of 25 MHz is necessary for operating a liquid crystal of 1,056 × 394 dots at about 60 Hz.

The refresh rate (60.08691 Hz) of the sub liquid crystal 31b having such a specification is slightly larger than the refresh rate (60.05124373 Hz) of the main liquid crystal 31a.
This means that the time required to scan (display) one screen including the blank area (time between vertical synchronization timings = rewrite (refresh) speed) is slightly shorter in the sub liquid crystal 31b.

FIG. 29 shows scanning (driving) positions at the same timing in both (a) and (b).
At the timing when the vertical back porch period corresponding to the vertical back porch 54b in the sub liquid crystal 31b shown in FIG. 29B ends, in the main liquid crystal 31a shown in FIG. 29A, the vertical back porch corresponding to the vertical back porch 54a. The period has not expired.
The sub liquid crystal 31b returns to the first pixel immediately after the timing shown in FIG. 29 and starts displaying the next screen, but there is still time until the vertical back porch period ends for the main liquid crystal 31a.
As a result, the vertical synchronization (refresh) timing is shifted between the main liquid crystal screen 31a and the sub liquid crystal 31b.

This state will be described in more detail using a synchronization signal or the like input to two liquid crystal screens.
FIG. 30 is a diagram comparing synchronization signals input to two liquid crystal screens in the fixed mode, where (i) is a synchronization signal input to the driver 36b of the sub liquid crystal 31b, and (ii) is a driver of the main liquid crystal 31a. A synchronization signal input to 36a is shown.
The length of the blanking period (the period corresponding to the vertical front porch 53 and the vertical back porch 54) is originally different between the main liquid crystal 31a and the sub liquid crystal 31b, but in the display of FIG. 30, they are displayed as the same length for convenience.
Since the refresh rate is different between the main liquid crystal 31a and the sub liquid crystal 31b, the length of the vertical synchronization period (display period + blanking period) differs between the two liquid crystals as shown in FIG. 30, and the input timing of the V-SYNC signal Is different.
The delay in the input timing of the V-SYNC signal becomes the delay in vertical synchronization (refresh) as it is, and as a result, the vertical synchronization delay of the main liquid crystal 31a with respect to the sub liquid crystal 31b as shown in FIG. 29 occurs.

FIG. 31 is a diagram for comparing DE signals input to two liquid crystal screens in the DE mode, in which (i) is a DE signal input to the sub liquid crystal 31b, and (ii) is input to the main liquid crystal 31a. The DE signal is shown.
Although the length of the blanking period (vertical front porch and vertical back porch) is originally different between the main liquid crystal 31a and the sub liquid crystal 31b, they are displayed as the same length for convenience in the display of FIG.
The valid period and invalid period in the DE signal of the main liquid crystal 31a are displayed as the valid period t1a, invalid period t2a, t3a, and t4a, respectively.
The valid period and invalid period in the DE signal of the sub liquid crystal 31b are displayed as the valid period t1b, invalid period t2b, t3b, and t4b, respectively.

Since the refresh rate is different between the main liquid crystal 31a and the sub liquid crystal 31b, the vertical blanking periods are different between the two liquid crystals as shown in FIG.
That is, the invalid periods t3a and t3b corresponding to the vertical back porches 54a and 54b are different, respectively, and the timings when the invalid periods t4a and invalid t4b corresponding to the vertical front porches 53a and 53b are also different.
As a result, as shown in FIG. 29, a shift (delay) in vertical synchronization timing (timing to start scanning of the next screen) of the main liquid crystal 31a occurs with respect to the sub liquid crystal 31b.

  Basically, the video displayed on the image display device synchronizes its frame rate with the refresh rate of the liquid crystal screen. Therefore, no matter what video is displayed on the main liquid crystal 31a and the sub liquid crystal 31b, Needless to say, it is preferable for the video display control that the timing of the vertical synchronization is appropriate.

As described above, the gaming machine of this embodiment includes the first frame buffer 156c, the second frame buffer 156d, the first frame buffer 156e, and the second frame buffer 156f for each of the main liquid crystal 31a and the sub liquid crystal 31b. Yes.
The first frame buffer and the second frame buffer are alternately used as a display frame buffer or a drawing frame buffer.
When one frame is drawn in the drawing frame buffer, the frame buffer becomes a display frame buffer, and the VDP 200 (display circuit 208) outputs a video signal based on the image developed in the display frame buffer to the main liquid crystal 31a. , Display on the sub liquid crystal 31b.
In the meantime, the VDP 200 (drawing circuit) develops (draws) an image of the next frame using one frame buffer as a drawing frame buffer.
Thus, in the gaming machine of the present invention, two frames of images exist for each of the main liquid crystal and the sub liquid crystal on the VRAM.
As a result, the vertical synchronization timing (refresh rate) between the two liquid crystal screens is deviated, so that the problem of misalignment of the display contents between the two liquid crystal screens becomes obvious as shown in FIG.

FIG. 32 is a diagram illustrating a display state shift state between liquid crystal screens due to a difference in refresh rate between a plurality of liquid crystal screens.
Here, a fixed mode example will be described.
FIG. 32A shows the relationship between the vertical synchronization signal of the sub liquid crystal 31b and the display frame, and FIG. 32B shows the relationship between the vertical synchronization signal of the main liquid crystal 31a and the display frame.
As described above, it is assumed that the refresh rate of the sub liquid crystal 31b is 60.08961 Hz, and the refresh rate of the main liquid crystal 31a is 60.05124373 Hz.
The sub liquid crystal 31b is slightly earlier in vertical synchronization timing than the main liquid crystal 31a.
It is assumed that moving images having the same frame rate (60 fps) are displayed using the main liquid crystal 31a and the sub liquid crystal 32b having such a relationship.
On the main liquid crystal 31a and the sub liquid crystal 31b, the frames of the first frame buffer and the second frame buffer are alternately displayed in accordance with the V-SYNC signal.
The contents displayed on both liquid crystal screens are the same or related to each other.
As shown in FIG. 32, since the refresh rates are different between the two liquid crystal screens, the timing of the V-SYNC signal is shifted with the passage of time.
As a result, the content of the image displayed on the sub liquid crystal 31b and the content of the image displayed on the main liquid crystal 31a are gradually shifted.

As shown in FIGS. 32A and 32B, the main liquid crystal 31a and the sub liquid crystal 31b simultaneously display the expanded frames in the main liquid crystal first frame buffer 156c and the sub liquid crystal first frame buffer 156e. .
After the first vertical synchronization signal V-SYNC (1) is input for both liquid crystals, the main liquid crystal 31a and the sub liquid crystal 31b are developed in the main liquid crystal second frame buffer 156d and the sub liquid crystal second frame buffer 156f, respectively. Is displayed.
At this point, it can be seen that the display contents of the main liquid crystal 31a and the sub liquid crystal 31b are slightly shifted. However, since the frames of the same frame buffer are displayed, this is not a big problem.
After that, V-SYNC (2), V-SYNC (3), V-SYNC (4), V-SNYC (5) and a vertical synchronizing signal are inputted, and display by the first frame buffer and display by the second frame buffer The display shift between the main liquid crystal 31a and the sub liquid crystal 31b becomes more prominent as these are alternately repeated.
After V-SYNC (6), the display between the two liquid crystals is completely deviated.
As shown in FIG. 32, the sub liquid crystal 31b displays a frame on the first frame buffer 156e, while the main liquid crystal 31a displays a frame on the second frame buffer 156d.
In order to solve this problem, in the present invention, as shown in (c), for example, the vertical synchronization timing (V-SYNC input timing) of the main liquid crystal 31a is adjusted to the sub liquid crystal 31b, etc. Match the vertical synchronization timing of the LCD screen.
Conversely, the vertical synchronization timing (V-SYNC input timing) of the sub liquid crystal 31b may be matched with the main liquid crystal 31a.

In the gaming machine of this embodiment, when there are a plurality of liquid crystal screens having different refresh rates, the control described below is performed in order to synchronize the vertical synchronization timing of the plurality of liquid crystal screens.
Basically, the vertical synchronization timing of one liquid crystal screen is controlled to match the vertical synchronization timing of another liquid crystal screen.

FIG. 33 is a diagram (No. 1) for explaining a display mode for adjusting the vertical synchronization timing of the two liquid crystal screens included in the gaming machine of this embodiment, where (a) is the main liquid crystal 31a, and (b) is the sub liquid crystal screen. A liquid crystal 31b is shown.
In the example shown in FIG. 33, the driver 36a forcibly returns to the first pixel for the main liquid crystal 31a that is still driving a halfway pixel at the timing when the scanning of the last pixel of the sub liquid crystal 31b is completed.
That is, a liquid crystal screen (main liquid crystal) with a low refresh rate value (screen display and rewriting is slow) at the timing when scanning of one screen is finished for a liquid crystal screen (sub liquid crystal 31b) with a high refresh rate value (fast display). For 31a), the scanning is ended halfway and the process returns to the first dot.
This can be realized by configuring the synchronization signal and DE signal input to the liquid crystal screen, which is slow in screen display and rewriting, in the fixed mode and the DE mode, respectively, as follows.

FIG. 34 is a diagram for explaining a synchronization signal in the fixed mode corresponding to the case of FIG.
(I) shows a synchronizing signal inputted to the sub liquid crystal 31b, and (ii) shows a synchronizing signal inputted to the main liquid crystal 31a.
In the gaming machine of this embodiment, as shown in FIG. 34 (b), for the main liquid crystal 31a having a small refresh rate value, the timing of the V-SYNC signal is advanced (actually shortened vertical back porch period), The timing is the same as that of the V-SYNC signal of the sub liquid crystal 31b shown in FIG.
The VDP 200 outputs a V-SYNC signal obtained by matching the timing of the V-SYNC signal to the sub liquid crystal 31b to the driver 36a of the main liquid crystal 31a.
The shortening of the vertical back porch period corresponds to the interruption of scanning shown in FIG.

Further, the difference in refresh rate between the main liquid crystal 31a and the sub liquid crystal 31b is very small. At the timing when the vertical back porch period for the sub liquid crystal 31b is finished, the driving of the effective pixel region 50a is finished for the main liquid crystal 31a as well. There is a high possibility that it is a back porch period.
When the vertical back porch period ends for the sub liquid crystal 31b and the vertical front porch period starts, no problem occurs in the image display of the main liquid crystal 31a even if the main liquid crystal 31a is forcibly set as the vertical front porch period. .

As shown in FIG. 26B, when the vertical blank areas 56 are set together, it is not necessary to consider the distinction between the vertical front porch 53a and the vertical back porch 54a.
In such a case, V-SYNC is input after the vertical blank area 56, but the V-SYNC signal is input to the main liquid crystal 31a at the same time as the V-SYNC input is input to the sub liquid crystal 31b. And the vertical synchronization timing of the sub liquid crystal 31b can be matched.

FIG. 35 is a diagram for explaining a synchronization signal in the DE mode corresponding to the case of FIG.
(I) shows a DE signal inputted to the sub liquid crystal 31b, and (ii) shows a DE signal inputted to the main liquid crystal 31a.
In the DE mode, after the DE signal becomes invalid for the main liquid crystal 31a, the vertical back porch period ends at the timing when the vertical back porch period ends for the sub liquid crystal 31b, and the vertical front porch ends at the same timing as the sub liquid crystal 31b. Start the period.
The VDP 200 outputs to the main liquid crystal 31a a DE signal in which the invalid period is adjusted so that the vertical synchronization timing of the main liquid crystal 31a matches that of the sub liquid crystal 31b.
That is, as shown in FIG. 35 (ii), by reducing the length of the invalid period t3 corresponding to the vertical back porch 54a, the timing when the invalid period t4 corresponding to the vertical front porch 53 (53a, 53b) is reached. You can match.
In this way, the vertical synchronization timing of the liquid crystal screen with the low refresh rate value (main liquid crystal 31a) and the liquid crystal screen with the high refresh rate value (sub liquid crystal 31b) is synchronized, and the next screen is the same from the top pixel. Display can be started at the timing.
As shown in FIG. 26B, when the vertical blank areas are set together, it is not necessary to consider the distinction between the vertical front porch 53a and the vertical back porch 54a.
That is, when the DE signal of the sub liquid crystal 31b is validated, the DE signal of the main liquid crystal 31a may be validated.
By shortening the vertical blanking period (t3 + t4) for the main liquid crystal 31a, the timing for starting the scanning (driving) of the effective pixel region can be adjusted for the next screen.

FIG. 36 is a diagram (part 2) illustrating a display mode for adjusting the vertical synchronization timing of two liquid crystal screens included in the gaming machine of the present embodiment.
In the case of FIG. 36, the refresh rate value is increased by delaying the timing of the V-SYNC signal (in the signal) and increasing the number of lines on the liquid crystal screen (sub liquid crystal 31b) with a large refresh rate value and a fast display. The timing of vertical synchronization is adjusted to the small liquid crystal display (main liquid crystal 31a) that is slow to display and rewrite.
This can be realized by configuring the synchronization signal and DE signal input to the fast-display liquid crystal screen in the fixed mode and the DE mode as follows.

FIG. 37 is a diagram for explaining a synchronization signal in the fixed mode corresponding to the case of FIG.
(A) shows the vertical synchronizing signal of the sub liquid crystal 31b, and (b) shows the vertical synchronizing signal of the main liquid crystal 31a.
In the gaming machine of this embodiment, as shown in FIG. 34 (a), the sub-liquid crystal 31b waits after a lapse of a prescribed period corresponding to the vertical back porch 54b, and the input timing of the V-SYNC signal is set to be higher than the actual timing. Slowly, the timing is the same as the vertical synchronization signal of the main liquid crystal 31a.
This standby period corresponds to the increased line shown in FIG.
The VDP 200 transmits a vertical synchronization signal as shown in FIG. 37A in accordance with the vertical synchronization timing (input timing of the V-SYNC signal) of the main liquid crystal 31a.
As shown in FIG. 26B, when the vertical blank areas 56 are set together, it is not necessary to consider the distinction between the vertical front porch 53b and the vertical back porch 54b.
Although the V-SYNC signal is input after the vertical blank area 56, the V-SYNC signal is input to the driver 36a of the main liquid crystal 31a and at the same time the V-SYNC signal is input to the driver 36b of the sub liquid crystal 31b. The vertical synchronization timing of the liquid crystal 31a and the sub liquid crystal 31b can be matched.

FIG. 38 is a diagram illustrating a DE signal in the DE mode corresponding to the case of FIG.
(A) shows the DE signal of the sub liquid crystal 31b, and (b) shows the DE signal of the main liquid crystal 31a.
In the DE mode, after the invalid period t3 corresponding to the vertical back porch 54a is reached for the sub liquid crystal 31b, the VDP 200 ends the invalid period t3 at the timing when the scanning of the vertical back porch 54a of the main liquid crystal 31a is completed. The invalid period t4 corresponding to the vertical front porch 53b is started at the same timing as the main liquid crystal 31a.
As shown in FIG. 26B, when the vertical blank areas are set together, it is not necessary to consider the distinction between the vertical front porch 53 and the vertical back porch 54.
That is, when the DE signal is enabled for the main liquid crystal 31a, the DE signal may be enabled for the sub liquid crystal 31b.
By extending the vertical blanking period (t3 + t4) for the sub liquid crystal 31b, the timing for starting scanning (driving) of the effective pixel region can be matched.

For three or more liquid crystal screens having different refresh rates, the vertical synchronization timings of all the liquid crystal screens can be adjusted by adjusting the vertical synchronization timing of the other liquid crystal screens to the reference liquid crystal screen as described above. I can do it.
In addition, the current VDP can only supply two systems (for example, for one main liquid crystal and one sub liquid crystal) of driving clocks (+ synchronization signals).
A case where there are three or more liquid crystal screens (for example, main liquid crystal + two or more sub liquid crystals) will be described.
When displaying an image using two or more sub liquid crystals using a driving clock different from that of the main liquid crystal, an image obtained by alternately mixing the images for each sub liquid crystal is developed in the VRAM, and at the timing of each image. A driving clock is alternately supplied to the sub liquid crystal.
By doing so, it is possible to simultaneously draw on two or more sub liquid crystals.

As the image display device of the gaming machine 1, a liquid crystal display device, a rear projector, and other arbitrary display devices can be adopted.
The display mode of the image display device of the present invention can be applied not only to pachinko machines, but also to slot machines, other gaming machines having display devices, and game machines in general.
