[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game machine such as a pachinko game machine or a coin game machine, and more particularly to a game machine including a variable display device whose display state can be changed, wherein a display result on the variable display device is predetermined. The present invention relates to a gaming machine in which a predetermined game value can be given when the display mode is changed to the display mode.

[0002]

2. Description of the Related Art As a gaming machine, a variable display device having a variable display portion whose display state can be changed is provided, and when a display result of the variable display portion becomes a predetermined specific display mode, the player is provided with a variable display device. Some are configured to shift to an advantageous jackpot game state. The variable display device includes a plurality of variable display units, and is generally configured to display the display results of the plurality of variable display units at different times.
On the variable display section, for example, a plurality of identification information such as symbols are variably displayed. Usually, that the display result of the variable display unit is a combination of predetermined specific display modes,
It is called "big hit." In addition, the game value is a right to make the state of the variable prize ball device provided in the game area of the gaming machine advantageous for a player who is easy to win a hit ball, or a right for the player to be in an advantageous state. Or to generate.

[0003] When a big hit occurs, for example, a big winning opening is opened a predetermined number of times, and the state shifts to a big hit game state in which a hit ball is easy to win. Then, in each open period, when a predetermined number (for example, 10) of winning prizes is won, the winning prize opening is closed. The number of opening of the special winning opening is fixed to a predetermined number (for example, 16 rounds). An opening time (for example, 29.5 seconds) is determined for each opening, and if the opening time elapses even if the number of winnings does not reach a predetermined number, the winning opening is closed. If the predetermined condition (for example, winning in the V zone provided in the special winning opening) is not satisfied at the time when the special winning opening is closed, the big hit gaming state ends.

[0004] In addition, among the combinations of the display modes of "outside" other than the combination of "big hit", at the stage where a part of the display results of the plurality of variable display portions has not been derived and displayed yet, the display results are already displayed. The state in which the display mode of the variable display unit that is derived and displayed satisfies the display condition that is a combination of the specific display modes is referred to as “reach”. A player plays a game while enjoying how to generate a big hit.

The progress of a game in a game machine is controlled by game control means such as a microcomputer. The identification information, the character image, and the background image displayed on the variable display device are controlled by display control means operating according to display control command data from the game control means.
The identification information, the character image, and the background image displayed on the variable display device generally include a display control microcomputer and a video display processor (FIG. 1) that generates image data in accordance with instructions from the microcomputer and transfers the image data to the variable display device side. VDP), and the display control microcomputer has a large program capacity. Therefore, the microcomputer of the game control means having a limited program capacity cannot control the identification information or the like displayed on the variable display device, and the display control microcomputer (microcomputer) is different from the microcomputer of the game control means. Display control means).

Therefore, the game control means for controlling the progress of the game needs to transmit a command for display control to the display control means. The generation of image data such as identification information is performed by the display control means, but the display position of the changing identification information on the screen every moment is preferably performed by the game control means for controlling the progress of the game. Is determined by the game control means. Therefore, the game control means determines the display position of the identification information at an appropriate timing and transmits the display position to the display control means.

[0007]

As described above, in the conventional gaming machine, since the display position of the changing identification information is determined by the game control means, the burden of control on the display of the identification information by the game control means is reduced. There is a problem in that the processing time that can be spent for other game control is limited in the game control means.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a gaming machine capable of reducing the control load on display of identification information by game control means.

As shown in FIG. 1, the pachinko gaming machine 1
It has a glass door frame 2 formed in a frame shape. On the lower surface of the glass door frame 2, there is a hit ball supply tray 3. Below the hitting ball supply tray 3, a surplus ball receiving tray 4 for storing prize balls overflowing from the hitting ball supply tray 3 and a hitting operation handle (operation knob) 5 for firing a hitting ball are provided. Behind the glass door frame 2,
The game board 6 is detachably attached. A game area 7 is provided on the front of the game board 6.

In the vicinity of the center of the game area 7, a variable display section 9 for variably displaying a plurality of types of symbols and a 7-segment L
A variable display device 8 including a variable display 10 using an ED is provided. In this embodiment, the variable display section 9 has three symbol display areas of “left”, “middle”, and “right”. On the side of the variable display device 8, a passing gate 11 for guiding a hit ball is provided. The hit ball that has passed through the passing gate 11 is guided to the starting winning opening 14 via the ball exit 13. In a passage between the passage gate 11 and the ball outlet 13, there is a gate switch 12 for detecting a hit ball that has passed through the passage gate 11. In addition, the winning ball that entered the starting winning port 14 is
It is guided to the back of the game board 6 and is detected by the starting port switch 17. In addition, a variable winning ball device 15 that performs opening and closing operations is provided below the starting winning port 14. The variable winning ball device 15 is opened by the solenoid 16.

Below the variable winning ball device 15, there is provided an opening / closing plate 20 which is opened by a solenoid 21 in a specific game state (big hit state). In this embodiment, the opening and closing plate 20 serves as a means for opening and closing the special winning opening. The winning ball that enters one (V zone) of the winning balls guided from the opening / closing plate 20 to the back of the game board 6 is detected by the V count switch 22. The winning ball from the opening / closing plate 20 is detected by the count switch 23. Variable display device 8
A start winning prize storage display 18 having four display sections for displaying the number of winning balls entering the starting winning prize port 14 is provided below. In this example, the start winning prize storage display 18 increases the number of lit display units by one each time there is a starting prize, with the upper limit being four. Then, each time the variable display of the variable display unit 9 is started, the number of the lit display units is reduced by one.

The game board 6 is provided with a plurality of winning ports 19 and 24. Decorative lamps 25 are provided around the left and right sides of the game area 7 so as to blink during the game.
There is an out port 26 for absorbing a hit ball that does not win. In addition, two speakers 27 that emit sound effects are provided at upper left and right sides outside the game area 7. A game effect LED 28a and a game effect lamp 2

Further, when a hit ball enters the starting winning opening 14 and is detected by the starting opening switch 17, the symbol in the variable display section 9 starts rotating if the symbol can be changed. If it is not possible to start changing the symbol, the start winning memory is increased by one. The start winning memory will be described later in detail. The rotation of the image in the variable display unit 9 stops when a certain time has elapsed. If the combination of images at the time of stop is a combination of big hit symbols, the game shifts to a big hit game state. That is, the opening and closing plate 20
Is released until a predetermined time elapses or until a predetermined number (for example, 10) of hit balls is won. Then, when a hit ball wins in the specific winning area while the opening and closing plate 20 is opened and is detected by the V count switch 22, a continuation right is generated and the opening and closing plate 20 is opened again. The generation of the continuation right is permitted a predetermined number of times (for example, 15 rounds).

If the combination of images in the variable display section 9 at the time of stoppage is a combination of big hit symbols with probability fluctuation, the probability of the next big hit becomes high. That is, a high probability state, which is more advantageous for the player, is obtained. Also, when the stop symbol on the variable display 10 is a predetermined symbol (hit symbol), the variable winning ball device 15 is opened for a predetermined time. Further, in the high probability state, the probability that the stop symbol on the variable display 10 hits the symbol is increased, and the opening time and the number of times the variable winning ball device 15 is opened are increased.

Next, the structure of the back surface of the pachinko gaming machine 1 will be described with reference to FIG. On the back of the variable display device 8, as shown in FIG. 2, a prize ball tank 38 is provided above the mechanism plate 36, and when the pachinko gaming machine 1 is installed on the gaming machine installation island, a prize ball is provided from above.

0 is provided. Of the prize balls guided to the prize ball collection cover 40, those that have won through the opening and closing plate 20 are controlled so that the ball payout device 97 pays out a relatively large number of prize balls (for example, 15). The winnings through the starting winning opening 14 are controlled so that a ball payout device (not shown in FIG. 3) pays out a relatively small number of prize balls (for example, six). Then, the winnings through the other winning ports 24 and the winning ball device are controlled so that the ball payout device pays out a relatively medium number of prize balls (for example, 10). Note that FIG. 3 illustrates the relay board 33 as an example.

Signals from the winning ball detection switch 99, the starting port switch 17 and the V count switch 22 are sent to the main control board 31 to perform the winning ball payout control. When the ON signal of the prize ball detection switch 99 is sent to the main control board 31, a prize ball number signal is sent from the main control board 31 to the prize ball board 37. The winning is detected by the winning ball detection switch 99. In this case, the main control board 31 sends a winning ball number signal to the winning ball board 37. For example, when the winning ball detection switch 99 is turned on in response to the turning on of the starting port switch 17, "6" is output as the winning ball number signal, and the winning ball detection is performed in response to the turning on of the count switch 23 or the V count switch 22. When the switch 99 is turned on, “15” is output as the prize ball number signal. And
If the winning ball detection switch 99 is turned on when those switches are not turned on, "10" is output as the winning ball number signal.

That is, the circuit on the firing control board 91 is controlled so that the hit ball is fired at a speed corresponding to the operation amount of the operation knob 5.

FIG. 5 is a block diagram showing the circuit configuration in the display control board 80 together with the CRT 82 for realizing the variable display section 9 and the output buffer circuit 63 of the main control board 31. The display control CPU 101 includes a control data ROM
When a strobe signal is input from the main control board 31 via the Schmitt trigger inverting circuits 105b and 105c of the input buffer circuit 105, display control command data is received via the input buffer 105a. I do. Then, display control of a screen displayed on the CRT 82 is performed according to the received display control command data. Specifically, a command corresponding to the display control command data is given to the VDP 103. VDP10

Even if a circuit in the display control board 80 is tampered with, a signal output by the tampering is not transmitted to the main control board 31 side.

Next, the operation of the gaming machine will be briefly described. FIG. 6 is a flowchart showing the operation of the basic circuit 53 in the main control board 31. As described above, this process is started, for example, every 2 ms by the reset pulse generated by the periodic reset circuit 66. Basic circuit 53
Is activated, the basic circuit 53 first performs a stack setting process for setting a designated address of a stack pointer (step S1). Next, an initialization process is performed (step S2). In the initialization process, the basic circuit 53
Determines whether an error is included in the RAM 55, and if an error is included, performs processing such as initializing the RAM 55. Then, after performing a process of setting a command code sent to the display control board 80 in a predetermined area of the RAM 55 (step S3), a process of outputting the command code as display control data is performed (step S3).
4).

Next, a process for transmitting a predetermined command for sound generation and LED lighting control to the lamp control board 35 and the voice control board 70 is performed, and a big hit to the hall management computer via the information output circuit 64. A process for transmitting data such as information, start information, and probability variation information is performed (data output process: step S5). In addition, various abnormality diagnosis processes are performed by the self-diagnosis function provided inside the pachinko gaming machine 1, and an alarm is issued if necessary according to the result (error process: step S6).

Next, a process of updating each counter indicating each random number for determination used in the game control is performed (step S).
7). In step S7, the basic circuit 53 counts up (adds 1) the big hit determination random number or the like as the determination random number. FIG. 7 is an explanatory diagram showing each random number. Each random number is used as follows. (1) Random 1: Determines whether or not to generate a big hit (for big hit determination) (2) Random 2-1 to 2-3: For left and right middle out-of-design symbol determination (3) Random 3: Design of big hit Determining a combination (for determining a big hit symbol = for determining a specific symbol) (4) Random 4: determining whether or not to reach at the time of a loss (for determining a reach) (5) Random 5: determining a reach type (determining a reach operation) for)

Incidentally, random numbers other than the above-mentioned random numbers (1) to (5) are also used to enhance the game effect. The variable display unit 9 also displays images other than the symbols, for example, a background, a character that moves in a predetermined manner, and the like, in order to enhance the gaming effect. In step S7, the basic circuit 53
Performs the count-up (addition of 1) of the random number for jackpot determination of (1) and the random number for specific symbol determination of (3). That is, they are the random numbers for determination.

Next, the basic circuit 53 performs a special symbol process (step S8). In the special symbol process control, a corresponding process is selected and executed according to a special symbol process flag for controlling the pachinko gaming machine 1 in a predetermined order according to a gaming state. Then, the value of the special symbol process flag is updated during each processing according to the gaming state. Further, a normal symbol process is performed (step S9). In normal symbol processing, 7 segment LE
A corresponding process is selected and executed according to a normal symbol process flag for controlling the variable display device 10 by D in a predetermined order. Then, the value of the normal symbol process flag is updated during each process according to the gaming state. Further, the basic circuit 53 inputs the states of the gate sensor 12, the starting port sensor 17, and the count sensor 23 via the switch circuit 58, and determines whether or not each of the winning openings and the winning devices has been won (step S10). .

The basic circuit 53 further performs processing for updating the display random number (step S11). That is,
The random number for determining a lost symbol in (2), the random number for reach determination in (4), and the random number for reach operation in (5) are counted up (addition of 1). However, random 2-2 is
The count is incremented when the carry of the random 2-1 occurs, that is, when the value of the random 2-1 becomes "15" and is returned to "0". Also, random 2-3
Is incremented when a carry of random 2-2 occurs, that is, when the value of random 2-2 becomes "15" and is returned to "0".

Further, the basic circuit 53 performs signal processing with the award ball substrate 37 (step S12). That is, when a predetermined condition is satisfied, a prize ball number signal is output to the prize ball substrate 37. CP for controlling the prize ball mounted on the prize ball substrate 37
U drives the ball payout device 97 according to the prize ball number signal. After that, the basic circuit 53 next executes the periodic reset circuit 6.
Step S1 until the reset pulse is given from Step S1
3 is repeated.

Next, a method for determining a symbol variably displayed on the variable display section 9 based on winning in the starting winning opening 14 will be described with reference to the flowcharts of FIGS. FIG. 8 shows a process for determining that the hit ball has won the start winning opening 14, and FIG. 9 shows a process for determining the stop symbol of the variable display of the variable display unit 9.

When the hit ball wins the starting winning port 14 provided in the game board 6, the starting port sensor 17 is turned on. In the switch processing of step S10, the basic circuit 53
Determines that the starting port sensor 17 has been turned on via the switch circuit 58 (step S41), and checks whether or not the number of stored starting winnings has reached the maximum value of 4 (step S42). If the start winning prize memory number has not reached 4, the starting prize storing number is increased by 1 (step S4).
3) Extract the value of the specific symbol determination random number. Then, it is stored in the random number value storage area corresponding to the value of the number of stored winning prizes (step S44). If the number of stored start winnings has reached 4, the process of increasing the number of stored start winnings is not performed. That is, in this embodiment, the number of hit balls that have won the maximum of four starting winning openings 17 can be stored.

The basic circuit 53 checks the value of the number of stored winning prizes in the special symbol process of step S8 (step S50). If the starting prize memory number is not 0,
While reading out the value stored in the random number value storage area corresponding to the number of start winning storages = 1 (step S51),
The value of the number of stored start winnings is reduced by one, and the value of each random number value storage area is shifted (step S52). That is,
The value stored in the random number value storage area corresponding to the number of start winning memorandums = n (n = 2, 3, 4) is calculated as follows:
It is stored in the random value storage area corresponding to n-1.

The jackpot determining means of the basic circuit 53 determines the hit / miss based on the value read in step S51, that is, the value of the extracted specific symbol determining random number (step S53). Here, the specific symbol determination random number takes a value in the range of 0 to 249. For example, when the probability is low, if the value is "3", it is determined as "big hit", and if it is any other value, it is determined as "out". When the probability is high, the value is "3",
If it is one of "7", "79", "103", and "107", it is determined as "big hit", and if it is any other value, it is determined as "out".

When it is determined that a big hit has occurred, the basic circuit 53 determines the stop symbol based on the value of the specific symbol determination random number. Here, if the limiter is not working,
A stop symbol is determined from a table including all symbols according to the value of the specific symbol determination random number (steps S54 and S55).
When the limiter is operating, the basic circuit 53 determines a stop symbol from a symbol table that does not include a symbol combination (probable symbol) that causes a probability change according to the value of the specific symbol determination random number (step S54, S56). The limiter is for restricting the occurrence of the jackpot due to the probable symbol continuously, that is, the continuation of the high probability state continuously. For example, if the high probability state continues four times in a row, the limiter is activated. Therefore, in the limiter operating state, the stop symbol is determined from the table that does not include the special symbol in which the probability change is performed.

Further, the basic circuit 53 extracts a reach operation random number (random 5) and determines a reach type based on the extracted value (step S57).

If it is determined that there is a loss, the basic circuit 5
3 determines whether or not to reach (step S5)
8). For example, when the value of the random number 4 which is a random number for reach determination is any one of “105” to “1530”, it is determined not to reach. Then, when the value of the reach determination random number is any of “0” to “104”, it is determined to be reach. When it is decided to reach, the basic circuit decides the reach symbol. In this embodiment, the left and right symbols are determined according to the value of the random 2-1 (step S59). Also, the middle symbol is determined according to the value of the random 2-2 (step S6).
0). That is, random 2-1 and random 2-2
Any symbol corresponding to the value of 0 to 15 is determined as the stop symbol. Here, when the determined middle symbol matches the left and right symbols, the symbol corresponding to the value obtained by adding 1 to the value of the random number corresponding to the middle symbol is set as the fixed symbol of the middle symbol so that it does not match the big hit symbol. I do. Further, the basic circuit determines a reach type according to the value of the random number 5 (step S57).

If it is determined in step S58 that no reach is made, the left and right middle symbols are determined according to the values of random 2-1 to 2-3 (step S61). As described above, it is determined whether the display mode of the symbol change based on the winning start is a big hit, a reach mode, or a loss, and the combination of the respective stop symbols is determined.

In the high probability state, the probability of the next big hit increases, the time until the variable display of the variable display 10 is determined by the 7-segment LED is shortened, and the variable display of the variable display 10 is reduced. The pachinko gaming machine 1 may be configured to increase the number of times and the opening time of the variable winning ball device 15 at the time of hitting based on the result, or the probability of hitting based on the variable display result of the variable display 10 is high. It may be constituted so that it may become.
Further, the present invention is also applicable to the pachinko gaming machine 1 in which only one or a plurality of these states occur.

For example, when the combination of symbols stopped on the variable display section 9 becomes a specific symbol, the probability of a big hit does not increase, but the variable winning ball device 15 at the time of hitting based on the variable display result of the variable display 10 does not increase. Even in a gaming machine in which the number of times of opening and the opening time are increased, if it is determined that the reach is to be made, it is determined whether or not the left and right stopped symbols match the display mode of the specific symbol, that is, which symbol is used to generate the reach state. The present invention is also applicable to gaming machines determined by means such as a predetermined random number. Further, the range of the random numbers and the random number values used in this embodiment is an example, and any random numbers may be used, and the range setting is arbitrary.

As described above, when a ball is hit in the starting winning opening 14, the basic circuit 53 determines in the special symbol process process of step S8 (see FIG. 6) whether to make a big hit or a non-hit, and a stop symbol. The display control command data according to the determination is displayed.
To the display control CPU 101. Basic circuit 5
3 performs a change speed changing process of each symbol in a subsequent special symbol process process. Then, display control command data corresponding to each process is given to the display control CPU 101 of the display control board 80. The display control CPU 101
The display of the variable display section 9 is controlled in accordance with each display control command data from the basic circuit 53.

FIG. 10 is a flowchart showing an example of a program for the special symbol process in the basic circuit 53. The special symbol process process shown in FIG. 10 is a specific process of step S8 in the flowchart of FIG. When performing the special symbol process process, the CPU 56 of the basic circuit 53 performs any one of steps S300 to S309 shown in FIG. 10 according to the internal state. In each process, the following processes are performed.

Special symbol change waiting process (step S30)
0): The start winning port 14 (in this embodiment, the winning port of the variable winning ball device 15) is hit and the start port sensor 17 is turned on. When the starting port sensor 17 is turned on, the starting winning memory number is increased by + if the starting winning memory number is not full.
1 and a big hit determination random number is extracted. That is, the processing shown in FIG. 8 is executed. Special symbol determination processing (step S301): When a state in which the variable display of the special symbol can be started, the number of start winning prizes is confirmed. If the number of start winning prizes is not 0, it is determined whether to make a jackpot or not according to the value of the extracted jackpot determination random number. That is, the first half of the processing shown in FIG. 9 is executed. Stop symbol setting process (step S302): A stop symbol for the left and right middle symbols is determined. That is, the middle half of the processing shown in FIG. 9 is executed.

Reach operation setting processing (step S30)
3): Whether or not the reach operation is performed is determined according to the value of the reach determination random number, and the variation mode of the reach operation is determined according to the value of the reach random number. That is, the latter half of the process shown in FIG. 9 is executed.

All symbols change start processing (step S30)
4): In the variable display section 9, control is performed so that all symbols start to change. At this time, with respect to the display control board 80,
Information for commanding the variation mode is transmitted. When a background or a character is also displayed on the variable display unit 9, control is performed so that display control command data corresponding to the background or character is transmitted to the display control board 80.

Waiting process for stopping all symbols (step S30)
5): Control is performed so that all symbols displayed on the variable display section 9 are stopped after a predetermined time has elapsed. Also, control is performed so that the left and right symbols are stopped at a predetermined timing until the timing of stopping all symbols. As will be described later in detail, in this embodiment, information such as the changed symbol variation speed is transmitted to the display control board 80 at the timing when the symbol variation speed of each symbol variation changes. Further, control is performed so that display control command data corresponding to a background or a character displayed on the variable display unit 9 is transmitted to the display control board 80 as appropriate.

Big hit display processing (step S306):
If the stop symbol is a combination of jackpot symbols,
The display control command data of the jackpot display is controlled to be sent to the display control board 80, and the internal state (process flag) is updated so as to shift to step S307. Otherwise, the internal state is changed to step S3.
Update to shift to 09. The combination of the big hit symbols is a combination in which the right and left middle symbols are aligned.
Further, the display control CPU 101 of the game control board 80 performs a big hit display on the variable display unit 9 according to the display control command data. The jackpot display is made to notify the player of the occurrence of the jackpot. Big winning opening opening process (step S307): Control for opening the big winning opening is started. Specifically, the counter and the flag are initialized, and the solenoid 21 is driven to open the special winning opening.

Processing during opening of the special winning opening (step S30)
8): Control for transmitting display control command data of the special winning opening round display to the display control board 80, processing for confirming establishment of the closing condition of the special winning opening, and the like are performed. If the closing condition of the special winning opening is satisfied, the internal state is updated to shift to step S307 unless the end condition of the big hit gaming state is satisfied. If the jackpot gaming state end condition is satisfied, the internal state is updated to shift to step S309.

Big hit end processing (step S309):
A display for notifying the player that the jackpot gaming state has ended is performed. When the display is completed, the internal flags and the like are returned to the initial state, and the internal state is updated so as to shift to step S300.

A module (step S4 in FIG. 6) for performing processing for transmitting display control command data in the game control program in accordance with the processing in each of the above-described steps includes:
The corresponding display control command data is output to the output port 57, and the strobe signal is output to the output port 57.

Next, the variation of the symbol will be described using a specific example. FIG. 11 is an explanatory diagram showing an example of the middle left and right symbols used in this embodiment and the order of change. As shown in FIG. 11, in this embodiment, each of the symbols displayed as the left and right middle symbols is the same 15 symbols in the left and right. Further, in this embodiment, after the symbol starts changing in the variable display section 9 of the variable display device 8, the middle symbol stops last.

In this embodiment, Reach 1 to Reach 5 are exemplified as reach modes. Of course, many reach modes other than the reach modes 1 to 5 illustrated below may be prepared.

FIG. 12 is an explanatory diagram for explaining an example of a symbol variation pattern. FIG. 13 is a timing chart showing an example of the change of the symbol at the time of the out of reach. FIG. 14 is a timing chart showing an example of the change of the symbol at the time of the reach (the case of the big hit and the case of the big hit).

As described above, when the basic circuit 53 detects the winning in the starting winning opening 14, when the symbol change can be started, the basic circuit 53 decides whether to make a big hit or lose, and the variable display section 9 The stop symbol in is determined.
Then, while giving display control command data according to the variation mode to the display control board 80, the lamp control board 35
And command data to the voice control board 70. The display control CPU 101 of the display control board 80 analyzes the display control command data received from the basic circuit 53, and controls the display of the CRT 82 constituting the variable display unit 9 in a mode instructed by the display control command data. Also,
The CPU mounted on the lamp control board 35 and the CPU mounted on the sound control board 70
The sound corresponding to the mode instructed by the command data received from the speaker 27 is emitted from the speaker 27, and the game effect lamps / LEDs 28a, 29b, 28c are controlled to blink.

If the basic circuit 53 decides not to generate a jackpot or reach, the display control CP
In accordance with the display control command data from the basic circuit 53, U101 and VDP 103
A signal is given to the variable display unit 9 so that the left and right symbols are changed as shown in (C) and (D).

In this example, “left” in the image display section 9

Then, when 6.800 seconds have elapsed, the symbols are controlled so that the symbol two symbols before the stopped symbol is displayed, and then the symbols are varied for 0.900 seconds according to the variation pattern b.

If the basic circuit 53 determines to generate a jackpot based on the winning start, or not to generate a jackpot but to reach, the display control circuit 81 determines the figure according to the command data from the basic circuit 53. Display control command data is given to the variable display unit 9 so that the left and right symbols as shown in FIGS. 14 (A) and (B) are changed.

Then, in the "left" symbol display area 9a in the image display section 9, as shown in FIG. 14A, the symbol is first changed for 5.000 seconds according to the change pattern a. Further, in the "right" symbol display area 9c in the image display section 9, as shown in FIG. 14B, the symbol is changed for 5.900 seconds according to the change pattern a. When 5.900 seconds have elapsed, the symbol is controlled so that the symbol two symbols before the stopped symbol is displayed, and the symbol is changed for 0.900 seconds according to the variation pattern b.

FIG. 14 (C) shows the pattern fluctuation at the time of the reach (both in the case of a big hit and in the case of no big hit).
It is a timing chart which shows the aspect of each fluctuation | variation of a middle symbol in FIG. As shown in FIG. 14C, in the reach 1, in the “medium” symbol display area 9 b in the image display unit 9,

, The symbol is changed for 6.800 seconds. Further, the symbol fluctuates according to the pattern e for 6.000 seconds, and then fluctuates for 0.600 seconds according to the fluctuation pattern d. The fluctuation pattern e is a pattern in which the fluctuation speed is gradually reduced for 0.680 seconds, and thereafter the fluctuation is performed at a constant speed such that the fluctuation is performed in 0.300 seconds per symbol. The fluctuation pattern d is 0.60
This is a pattern in which the fluctuation speed is gradually reduced for 0 second to stop the fluctuation.

In Reach 3, in the "medium" symbol display area 9b in the image display section 9, first, the symbols are changed for 6.800 seconds according to the change pattern a. Subsequently, the fluctuation is performed for 5.656 seconds according to the fluctuation pattern d. The fluctuation pattern d is a pattern that is gradually delayed and stops. Further, with the symbol being paused for 0.300 seconds, the fluctuation with the fluctuation pattern a is performed for 3.400 seconds, and the fluctuation with the fluctuation pattern d is performed for 5.656 seconds.

In Reach 4, after the fluctuation is performed in the same manner as in Reach 1, the fluctuation of the symbol is stopped for 0.380 seconds from the timing (R) shown in FIG.
The fluctuation is performed according to the fluctuation pattern g for 00 seconds. The fluctuation pattern g is a fluctuation pattern in which the fluctuation in the forward direction and the fluctuation in the reverse direction for 0.9 symbols are performed.

Further, the symbol fluctuates in accordance with the pattern e for 5.656 seconds, and thereafter, with a symbol pause for 0.300 seconds, a so-called frame feed pattern is performed. In the change by the frame feed, the change of one symbol in 0.450 seconds is performed 9 to 15 times, and the symbol pause of 0.318 seconds is performed 8 to 14 times. Then, the fluctuation is performed in accordance with the fluctuation pattern f for 1.050 seconds with the symbol pause for 0.300 seconds. The variation pattern f is 0.
This is a constant speed fluctuation pattern in which one symbol fluctuates in 075 seconds, and 14 symbols fluctuate in 1.050 seconds.

FIG. 15 is an explanatory diagram showing display control command data transmitted from the main control board 31 to the display control board 80. As shown in FIG. 15, in this embodiment,
The display control command data includes display control signals CD0 to CD
7 from the main control board 31 to the display control board 8
Sent to 0. Further, between the main control board 31 and the display control board 80, a signal line of a display control signal INT for transmitting a strobe signal, a supply line of + 5V and + 12V serving as a power supply of the display control board 80, and a ground level Are also wired.

FIG. 16 is a timing chart showing an example of transmission timing of display control command data given from the main control board 31 to the game control board 80. In this example, the 2-byte display control data making up the display control command data is transmitted every 2 ms as shown in FIG.
Then, a strobe signal (display control signal INT) is output in synchronization with each display control data. Display control CP
The U101 receives an NMI interrupt (non-maskable interrupt) at the rising edge of the strobe signal.
The display 101 can capture each display control data by the NMI interrupt processing program.

As will be described in detail later, in this embodiment, the main control board 31 sends the display control board 80 from the main control board 31 at the changing point of the changing speed of the symbol change and the display changing point of the background and the character. , Display control command data indicating the changed display mode is transmitted only once. Accordingly, the display control can be started immediately in the display control board 80, and the load related to the display control of the basic circuit 53 of the main control board 31 is greatly reduced. On the other hand, if a display omission of display control command data occurs, display control deviates from normal control. Therefore, the strobe signal is input to the NMI terminal of the display control CPU 101 so that the display control command data is not missed.

FIGS. 17 to 23 are explanatory diagrams showing examples of the structure of the display control command data. FIG. 17 shows display control command data for instructing symbol fluctuation and symbol stop for the left symbol. As shown in FIG. 17, display control command data composed of 2-byte display control data CMD1 and CMD2 allows each variation pattern
It is specified that the left symbol should fluctuately stop and the left stop symbol at that time. In these designations, the value of the display control data CMD1 in the first byte is “80 (H)”.
It is.

FIG. 18 shows display control command data for instructing symbol fluctuation and symbol stop for the right symbol. As shown in FIG. 18, the display control command data composed of the 2-byte display control data CMD1 and CMD2 specifies each variation pattern, that the right symbol should be stopped and the right stop symbol at that time. . In these designations, the value of the display control data CMD1 in the first byte is “81 (H)”. FIG.

FIGS. 20 and 21 are explanatory diagrams showing display control command data for instructing the display of each of the left and right symbols and display control command data for instructing the display position of the left and right symbols on the screen. is there. FIG. 20 shows display control command data for instructing display of a left symbol and a right symbol. When receiving the display control command data, the display control CPU 101 controls to display the designated left and right symbols regardless of the immediately preceding display symbol. FIG. 21 shows display control command data for instructing display of a medium symbol. Display control C
When receiving these display control command data, the PU 101 controls to display the designated middle symbol regardless of the immediately preceding display symbol. The value of the display control data CMD1 in the first byte for the left symbol is “84 (H)”.
And the first byte of display control data C for the right symbol
The value of MD1 is “85 (H)”, and the value of the first byte of display control data CMD1 for the middle symbol is “86”.
(H) ".

FIG. 21 also shows display control command data indicating the display position of the middle left and right symbols on the screen.
When the display control CPU 101 receives the display control command data, the display control CPU 101 sets the display area of the middle left and right symbols on the display screen to a normal position (approximately the center in this embodiment) or a lower part of the screen. The value of the display control data CMD1 of the display control command data indicating the display position of the middle left and right symbols is “87 (H)”.

FIG. 22 is an explanatory diagram showing display control command data for instructing a character, background, and error display. When the value of the display control data CMD1 is “88”
(H) "indicates data relating to a character, and the value of the display control data CMD1 is" 89 ".
(H) "indicates data related to the background, and the value of the display control data CMD1 is" F8 ".
The display control command data of “(H)” indicates data related to error display.

FIG. 23 shows display control command data for instructing display contents in the big hit game state. The display control command data in which the value of the display control data CMD1 is “90 (H)” is data that specifies the display screen in each round, and the value of the display control data CMD1 is “91 (H)”.
The display control command data of “(H)” is data for specifying the number of rounds to be displayed in each round. The display control command data in which the value of the display control data CMD1 is “92 (H)” is data for specifying the display of the big hit symbol, and the value of the display control data CMD1 is “93 (H)”.
The display control command data of “(H)” is data for indicating that a prize has been won in a specific area (V zone) and for erasing it.

The above-described display control command data is transmitted from the main control board 31 to the display control board 80 only once at a predetermined timing. As is clear from the description of FIGS. 17 to 23, the display control command data is transmitted at the time of switching the display such as the symbol variation speed. Note that each value shown in FIGS. 17 to 23 is an example, and the value of the display control command data is determined in consideration of ease of control and ease of design in each gaming machine.

The operation of a specific example will be described below with reference to the explanatory diagram of FIG. 24 and the flowchart of FIG. Here, as an example, a case where the reach 4 fluctuates will be described. C in the basic circuit 53 of the main control board 31
It is assumed that the PU 56 decides to perform the symbol change in the mode of the reach 4 due to the big hit in the special symbol process processing.

Then, for example, display control command data of “stage and dim distant view” and “Daimyo appears” are sequentially transmitted to the display control board 80. Further, display control command data of “left symbol low-speed fluctuation”, “right symbol low-speed fluctuation”, and “middle symbol low-speed fluctuation” are sequentially transmitted based on a predetermined priority. In the display control board 80,
When the display control CPU 101 sequentially receives the display control command data, the display control CPU 101 first gives a display instruction of “stage and dim distant view” to the VDP 103, and the character “Daimyo” is displayed.
Is given. The VDP 103 displays the background corresponding to the screen and the character “Daimyo” at a predetermined position on the screen in response to these instructions. In addition,
After that, the VDP 103 performs control to move the character in accordance with a predetermined motion order. Also,
This timing corresponds to the timing (b) in FIG. The variation of the background, the character, and the design is, for example, as shown in FIG.

The CPU 56 of the main control board 80 sends “left symbol middle speed fluctuation” and “right symbol middle speed variation” to the display control board 80 at predetermined timings between timings (b) to (c) in FIG. Display control command data of "speed fluctuation" and "medium symbol medium speed fluctuation" are sequentially transmitted. After that, "Left symbol high speed fluctuation", "Right symbol high speed fluctuation", "Medium symbol high speed fluctuation"
Are sequentially transmitted. When receiving the display control command data, the display control CPU 101 instructs the VDP 103 to change the fluctuation speed.
The VDP 103 controls the symbol change speed according to the instruction. By such control, a fluctuation pattern a (gradually increasing the speed and then changing at a constant speed) is realized.

In this example, the middle left and right symbols "n", "n",
It is assumed that a big hit is generated by "n". Therefore, at the timing (c), the CPU 56 of the main control board 80
The display control command data instructing to display “12” two symbols before “n” on the left symbol is transmitted, and then,
The display control command data of “left symbol middle speed fluctuation” is transmitted. Then, at a predetermined timing, the “left symbol low-speed fluctuation”
Is transmitted. Here, the predetermined timing is a timing at which the two symbols fluctuate when 0.9 seconds elapse from the timing (c) if the fluctuation speed is reduced at that timing. Then, at timing (d), display control command data for instructing that the left symbol stops at "n" is transmitted. With the above control, the fluctuation pattern b for the left symbol (0.9 seconds gradually slowed down and stopped (two symbol fluctuations))
And the stop symbol "n" is realized.

The CPU 56 of the main control board 80
The display control command data instructing to display "twelfth" two symbols before "n" on the right symbol is transmitted, and then,
The display control command data of “right symbol middle speed fluctuation” is transmitted. Then, at a predetermined timing, the “right symbol low-speed fluctuation”
Is transmitted. At timing (e), display control command data instructing that the right symbol stops at "n" is transmitted. With the above control, the fluctuation pattern b and the stop symbol “n” are realized for the right symbol.

When the right symbol is stopped, the left and right symbols stop at "n" and "n", so that the reach is achieved. Further, in this example, a character of “big feet” appears in the reach 4. Therefore, the CPU 56 of the main control board 80
Transmits the display control command data of "Big foot appears". When the display control CPU 101 sequentially receives the display control command data, the display control CPU 101 gives the VDP 103 a display instruction of the character “big feet”. The VDP 103 displays the character “big feet” at a predetermined position on the screen according to the instruction. Further, the display control CPU 101
The display control command data of “move the special symbol display area downward” is transmitted. When the display control CPU 101 sequentially receives the display control command data, the VDP 103
Is instructed to change the symbol display position. The VDP 103 moves the symbol display position downward on the screen according to the instruction. With the control described above, the display state of the screen is
The state shown in FIG. 24A changes to the state shown in FIG.

Then, the CPU 56 of the main control board 80
First, display control command data for instructing “medium symbol medium speed fluctuation” is transmitted in order to realize the fluctuation pattern c (stop gradually and slowly) for the medium symbol. Then, the display control command data of “medium symbol low-speed fluctuation” is transmitted at a predetermined timing. Timing shown in FIG.
Then, the CPU 56 of the main control board 80 transmits the display control command data instructing that the middle symbol stops at "n". And when it comes to the timing (re '),
The display control command data of "the middle symbol performs the swinging operation" is transmitted.

Further, after 1.100 seconds (at timing (nu)), display control command data for instructing that the middle symbol stops at "n" is transmitted. When the display control CPU 101 receives the display control command data of “the middle symbol performs a swinging operation”, the display control CPU 101 first sets 0.55
VDP so that the middle symbol fluctuates forward by 0.9 symbol in seconds
Instruct 103, 0.55 seconds later, medium symbol 0.9
An instruction is issued to the VDP 103 to reversely change by the symbol. As a result, the display state is as shown in FIG.

Thereafter, the big hitting game state is entered, and the CPU 56 of the main control board 80 executes the “screen before opening the first big winning opening”.
Is transmitted to the display control board 80, and in accordance with the progress of the big hit game, the display control command data of the "large win opening screen of each round" and the display control command data indicating the "number of rounds" are appropriately changed. It is transmitted to the display control board 80. In addition, display control command data relating to the “V” display is appropriately transmitted to the display control board 80, and if necessary, display control command data for designating a new background or character is displayed at a predetermined timing.
Send to

As described above, the CPU 5 of the main control board 80
Numeral 6 transmits display control command data at the timing of changing the speed of changing the symbol, the timing of switching the background, the appearance timing of the character, and the like. In this embodiment, at these timings, the display control command data composed of 2 bytes is transmitted only once, so that the load required for the display control of the CPU 56 is reduced. Also, since one display control command data specifies only one operation, the display control command data creation process of the CPU 56 is also simplified. At the same time, display control CP
The display control command data analysis process in U101 is also simplified.

On the display control board 80 side, display control is performed in accordance with the latest command received in the past, for portions other than those specified by the received display control command data. For example, at a timing (c) shown in FIG. 14, display control command data for instructing a middle speed change of the left symbol is transmitted, but the right symbol, the middle symbol, the character, and the background are affected by the display control command data. Instead, the variation of the middle right symbol and the background display state are in accordance with the latest command received before that.

Further, when it is necessary to transmit a plurality of display control command data at one timing, they are transmitted according to a predetermined priority. As is clear from the above description, in this embodiment, the background → character →
The priority is lower in the order of left symbol → right symbol → middle symbol.

FIG. 26 is a flowchart showing the display control command data receiving process of the display control CPU 101 in the display control board 80. As described above, the strobe signal from the main control board 31 is used for the display control CPU 10.
No. 1 is input to the NMI interrupt terminal, so that whatever process the display control CPU 101 is performing,
Display control command data is received by the NMI interrupt process. Each display control data from the main control board 31 is input to an input port in the display control CPU 101. Note that an NMI interrupt is applied to the display control CPU 101 at the rising edge of the signal.

In the NMI interrupt processing, the display control CP
U101 first checks whether the data receiving flag is set (step S701). If not set, this interrupt is an interrupt caused by the transmission of the first byte of display control data in the display control command data. Therefore, the pointer is cleared (step S702), and the data receiving flag is set (step S703). The pointer indicates which byte in the display control command data storage area in the RAM built in the display control CPU 101 stores the received data.

When the data receiving flag is set, the display control CPU 101 inputs data from the input port and stores the input data at the address indicated by the pointer in the display control command data storage area. (Step S705).

Then, the display control CPU 101 increments the value of the pointer by one (step S706). Then, when the value of the pointer becomes 2, it means that the reception of the display control command data composed of 2 bytes has been completed, so that the data reception completion flag is set and the data reception flag is reset. (Step S708,
S709). With the above processing, the display control data CMD1 and CMD2 are received by the display control board 80.

FIG. 27 is a flowchart showing a schematic operation of the display control CPU 101 relating to display control. Upon receiving the display control command data in which CMD1 is 80 (H) or 84 (H) (step S801), the display control CPU 101 instructs the VDP 103 on the change state of the left symbol according to the display control command data (step S801). Step S802). When the display control command data in which the CMD1 is 81 (H) or 85 (H) is received (step S803), the control unit instructs the VDP 103 to change the right symbol according to the display control command data (step S804). Further, when the display control command data whose CMD1 is 82 (H) or 86 (H) is received (step S805), the control unit instructs the VDP 103 to change the middle symbol according to the display control command data (step S806).

When display control command data in which CMD1 is 87 (H) is received (step S807), VDP
103 is instructed to change the symbol variation area on the screen (step S808). When the display control command data in which CMD1 is 88 (H) is received (step S80)
9) While instructing the VDP 103 to change the display of the character (step S810), receiving the display control command data in which CMD1 is 89 (H) (step S810)
811) The VDP 103 is instructed to change the display of the background (step S812). Then, upon receiving the display control command data in which CMD1 is F8 (H) (step S8)
13) Instruct the VDP 103 to display an error (step S814).

FIG. 28 is an explanatory diagram for describing an error display method according to this embodiment. For example, FIG.
It is assumed that a display as shown in FIG. 8A has been made on the display unit of the CRT 82. In this state, when the CPU 56 of the main control board 80 detects an abnormality (disconnection or short circuit) of the count switch 23, CMD1 = F8 (H), CMD2 =
Display control command data of 03 (H) to the display control board 8
Send to 0. Upon receiving the display control command data, the display control CPU 101 instructs the VDP 103 to display an abnormality of the count switch 23. V
In response to the instruction, the DP 103 performs a display indicating an abnormality of the count switch 23 in a predetermined area in the screen as shown in FIG.

As described above, in this embodiment, the display control is performed in accordance with the latest command received in the past for portions other than those specified by the received display control command data. Therefore, even if the display control command data of CMD1 = F8 (H) is received, the display state of the background, the character, and the pattern does not change.

When the CPU 56 of the main control board 80 detects that the count switch 23 has been restored to the normal state,
The display control command data of “erase error display” in which CMD1 = F8 (H) and CMD2 = 00 (H) is transmitted to the display control board 80. The display control CPU 101
Upon receiving the display control command data, the VDP 10
3 is instructed to erase the display of the abnormality of the count switch 23. The VDP 103 deletes the error display according to the instruction. As a result, the display state is as shown in FIG.
The state returns to the state shown in FIG.

If the VDP 103 can manage a plurality of sprites, the background is displayed on one sprite and the error is displayed on another sprite, so that the error display can be easily superimposed on a part of the screen. Screens can be generated. Note that the VDP 103 can also control to insert an error display screen in a part of the background screen when an error display is instructed.

As described above, when the display control command data for instructing the error display is received from the main control board 31, the display control CPU 101 performs the error display while maintaining the display state at that time. . Therefore, an error display is promptly performed. When the display control command data of “erase error display” is received, the display control CPU 101 can immediately reproduce the screen before the occurrence of the error only by erasing the error display. Therefore, the recovery from the error display is quick.

In the pachinko gaming machine 1 according to each of the above-described embodiments, when a special symbol variably displayed on the variable display section 9 based on a start winning prize becomes a predetermined symbol combination, a predetermined game value is obtained. Although it was a first-class pachinko gaming machine that can be given to a player, a predetermined game value that can be given to a player when there is a prize in a predetermined area of an electric accessory that is opened based on a start winning prize. Two types of pachinko machines,
A third-type pachinko gaming machine in which a predetermined right is generated or continued when there is a prize in a predetermined electric accessory which is opened when a stop symbol of a symbol variably displayed based on a start winning prize is a predetermined combination of symbols. Even so, the present invention can be applied.

[0107]

As described above, according to the present invention, the gaming machine is configured to transmit only the control command relating to the portion where the game control means changes at the display change timing to the display control means. This has the effect of reducing the burden of controlling the identification information display of the means.

When the display control means receives a control command, display portions other than the portion based on the control command are configured to perform display control based on the latest command received in the past. The display control is normally performed even if only the control command relating to is transmitted.

When the game control means needs to transmit a plurality of control commands at the same timing, the game control means is configured to transmit each control command in time series based on a predetermined display priority. In this case, display control can be normally performed even when a plurality of display control changes must be made at one change timing.

When the game control means is configured to transmit the control command only once at the change timing, the display control means can promptly start the display control based on the control command. When the display control means is configured to receive the control command by the non-maskable interrupt, the display control means is configured to receive the control command reliably and to transmit the control command only once. The display control is normally performed even when the user is in the display.
