[0002]

2. Description of the Related Art In this type of gaming machine, there has been one generally known in the past, for example, as shown in FIG.

FIG. 14 shows a case of a pachinko game machine as an example of a game machine, and a game control board 8 provided with a game control computer for controlling the game machine.
0 is provided in the pachinko gaming machine, and a pachinko machine is provided with a display control board 81 provided with a display control computer for controlling a variable display device whose display state can be changed. The computer for game control provided on the game control board 80 is provided with a random counter as an example of numerical data updating means. If the random counter counts up from 0 and counts up to its upper limit of 377, it will be restarted. It was configured to count up from 0 again.

When a hit ball hit into the game area wins the start winning area and is detected by the start winning ball detection switch 25 as an example of the start winning ball detecting means, the detection signal is transmitted to the game control computer. Is input to The count value of the random counter is extracted at the timing of the input of the signal, and when the extracted value is, for example, “7”, it is determined in advance to generate a specific game state (big hit state). A display control command signal is output to the display control computer 81 to change the display result of the variable display device to a specific display mode of, for example, “777”, so that it is possible to control to a gaming state advantageous to the player. I was

[0005] From the game control computer of the game control board 80 to the display control computer of the display control board 81, CD0 to CD7, INT as display control command signals.
Is output. This INT is an interrupt signal, and INT is
Is received, the display control computer enters an interrupt state and performs control to take in the command data of CD0 to CD7. Conventionally, the INT signal has been output one pulse at a time each time the random counter is updated by adding "1".

[0006]

On the other hand, there has been an inconvenience that a specific gaming state (big hit state) is frequently generated by remodeling a gaming machine. As shown in FIG. 14, this illegal remodeling is performed by assembling a game machine with an illegal board 80 'on which a computer similar to the game control computer provided on the game control board 80 is mounted. Is detected once by the illegal board 8
0 'is input to the game control computer, and an output signal from the game control computer is sent to the game control board 8
0 is input to the input port of the start winning ball detection signal in the game control computer. Then, as shown in FIG. 14, a part of the signal line from the start winning ball detection switch 25 to the game control board 80 is cut off (see the crosses in FIG. 14).

On the other hand, similarly to the game control computer of the game control board 80, the game control computer provided on the illegal board 80 'counts up from 0, counts up to the upper limit of 377, and then returns to 0 again. A random counter similar to the above is provided, which starts counting up again. When the game machine is powered on, the game control computer of the game control board 80 and the unauthorized board 80 '
Both of the game control computer and the computer start up at the same time,
Both random counters simultaneously start counting up from “0”. However, although the same type of crystal oscillator is used for the crystal oscillator for generating a clock signal for the game control computer of the game control board 80 and the game control computer for the illegal board 80 ', some individual oscillators are used. Generally, due to the difference, the update periods of both random counters are slightly shifted. Therefore, FIG.
As shown in the figure, the INT signal output every time the random counter of the game control board 80 is updated by adding "1" is modified to be taken into the game control microcomputer of the illegal board 80 '. Correcting the addition operation of the random counter of the illegal board 80 ', the game control board 8
The random counter on the fraudulent substrate 80 'is counted up so as to be accurately synchronized with the 0 random counter.

[0008] The jackpot determination value of the random counter of the gaming machine targeted for unauthorized remodeling is, for example, "7".
In this case, if the start winning ball detection signal from the start winning ball detection switch 25 is input to the game control microcomputer of the fraudulent board 80 ', the fraudulent board 80'
At the timing immediately before the count value of the random counter on the side becomes "7", a fraudulent signal is output from the fraudulent board 80 'side to the input port of the start winning prize ball detection signal of the game control microcomputer of the game control board 80. You. Then, the game control computer receiving the illegal signal extracts the count value of the random counter at the input timing of the illegal signal. As a result, a random value of “7” is always extracted, and the specific game state (big hit state) frequently occurs.

Then, the value is incremented and updated by one every 2 msec, counted up from 0, counted up to its upper limit of 12, and then counted up again from 0. The WC RNDC is used to predetermine a scheduled stop symbol displayed by the middle variable display unit 2b when it is preliminarily determined to be out, and is added and updated by one every 2 msec and uses the reset waiting time. And is updated in an infinite loop. Then, it counts up from 0, counts up to its upper limit of 15, and then counts up again from 0. WCR
NDR is the right variable display unit 2 when it is determined in advance that it is off.
This is for predetermining the scheduled stop symbol displayed by c. Then, the value is incremented and updated by one at every carry of the WC RNDC, counted up to 0, which is the upper limit of 12, and then counted up from 0 again.

The WC RND ACT is for predetermining the type of reach. Then, the value is incremented and updated by one every 2 msec, counted up from 0, counted up to its upper limit of 14, and then counted up again from 0.

The WC RND SLW is for determining the symbol deceleration number in advance. The WC RND AC
If the reach for performing the symbol deceleration display control is previously selected and determined by T, the left variable display section 2a and the right variable display section 2c stop to enter the reach display state, and then the middle variable display section 2b Before the stop, a scroll display is performed in a state of being decelerated by a plurality of symbols, and then a stop display is performed. The number of symbols for deceleration scroll display is
It is randomly determined in advance by the WC RND SLW. This WC RND SLW is 2mse
The value is incremented by one for each c, counted up from 0, counted up to its upper limit of 2, and then counted up again from 0.

FIG. 5B is a schematic flowchart showing the variable display control of the variable display device 1. This FIG. 5 (b)
Shows an example of setting 1 among setting 1, setting 2, and setting 3 described above. Therefore, as shown in the figure, it is shown that WC RND1 counts up within the range of 0 to 353. In the case of the setting 2, this is 0 to 377, and in the case of the setting 3, it is only 0 to 395. Since there is no change in other cases, the illustration and description are omitted.

In the normal game state where the probability is not high, W
When the extracted value of C RND1 is “7”, it is determined in advance that a big hit is to be generated, the count value of WC RNDL is extracted, and a symbol of a type corresponding to the extracted value (random number) is displayed on the left variable display section 2a, Right variable display 2c, middle variable display 2
b. Control is performed to stop and display each. As a result, the stop display symbols of the left, right, and middle variable display portions 2a, 2c, and 2b become random symbols, and a symbol combination in which a big hit occurs is displayed.

On the other hand, when the extracted value of WC RND1 is other than "7", the left variable display section 2a, the middle variable display section 2b, and the right variable display section 2c are stopped and displayed by the extracted values of WC RNDL, C and R. Let it. In addition, in this case, if it is random and coincides with the big hit symbol, WC RND
1 is subtracted by 1 to set the scheduled stop symbol of the middle variable display section 2b to 1
Stop display control by shifting only the symbol.

On the other hand, at the time of high probability, if the extracted value of WC RND1 is any one of 7, 71, 131, 197, 263, 331, it is determined in advance that a big hit will occur, and Stop display control is performed according to the extracted value. Then, at high probability, WCR
When the extracted value of ND1 is 7, 71, 131, 197, 263,
331, the WC RNDL, C,
Stop display control is performed according to the extracted value of R.

As described above, at the time of the high probability, the probability of occurrence of the big hit is improved six times as compared with the time of the normal game. In the normal gaming state, the probability of occurrence of a big hit is 1/354 in the case of the setting 1, 1/378 in the case of the setting 2, and 1/396 in the case of the setting 3.

FIG. 6 shows command data CD0 to CD7,
5 is a timing chart illustrating an operation of transmitting an INT signal. The command data is composed of eight pieces of data, and a set of display command signals is composed of the eight pieces of command data. Then, a periodic reset signal from the periodic reset circuit 34 is input to the basic circuit 30 every 2 msec. Then, the CPU (main control CPU) of the basic circuit 30 outputs eight command data of 0 to 7. The display control signal INT is output in accordance with the output of each command data. This display control signal INT
Is an interrupt signal, and the display control microcomputer receiving the interrupt signal enters an interrupt state, and fetches the transmitted command data CD0 to CD7 one by one.

In this INT, as shown in FIG. 6, one pulse is 3.9 μm, and an interval from a certain pulse to an adjacent pulse is 68.4 μs.

When the next periodic reset signal is input, the main control CPU does not output any command and INT. Further, when the next periodic reset signal is input, the main control CPU compares the previously transmitted command data with the command data to be transmitted this time, and when the two do not agree with each other, that is, attempts to transmit this time. If the present command data is new command data, the command data is output in the same manner as the previous one. On the other hand, if the command data to be output this time is exactly the same as the previous data, the main control CPU does not output any command data.

As described above, when the contents of the command data are different every time, the main control CPU sets the command data every 4 msec.
A set of command data consisting of blocks is output. By transmitting the display control command data within one interrupt, the display control microcomputer can immediately respond to the switching of the display contents. In addition, since the output of the command data is performed not every one interrupt but every two interrupts, that is, once for a plurality of interrupts, the interrupt is executed every time the command data is output. The other processing contents (display control processing and the like) that could not be processed before the processing can be reliably performed next time, and the processing load on the display control microcomputer can be reduced.

FIG. 7 is a main flowchart showing the operation of the basic circuit 30 of the game control circuit shown in FIG. First, a stack pointer address is set in step S (hereinafter simply referred to as S) 1 and initialization processing is performed in S2. Next, the process proceeds to S3, where a probability setting process is performed. This probability setting process is a process of determining which of setting 1, setting 2, and setting 3 has been set by operating means that can be operated only by a game hall attendant, and storing the set value. Next, the program proceeds to S4, in which hit ball signal processing is performed. The hit ball signal processing pays out based on the hit ball signals A and B transmitted from the payout control microcomputer for paying out the balls and the detection signals from the specific winning ball detection switch 8 and the count switch 26. The control operation is performed to return the number of prize balls to the payout control microcomputer.

Then, the program proceeds to S5, in which a process for calculating a symbol average rotation time is performed, the process proceeds to S6, an output data control process is performed, the process proceeds to S7, a process for setting output data is performed, and the process proceeds to S8, where data output is performed. The process proceeds to S9, where a display control process is performed. This display control process is a process for transmitting command data for display control to the variable display control circuit shown in FIG. 3 for controlling the variable display device 1. Next, the process proceeds to S10, where an alarm process is performed.
This alarm processing is to display an alarm or an alarm sound when an abnormal situation such as a short-circuit of the count switch 26 or an undetectable state such as a shift of the count switch 26 to a position where a ball cannot be detected occurs. This is a control for generating or the like.

Next, the process proceeds to S11, where a random update process is performed. Next, in S12, a switch process is performed, and the detection signals of the start winning ball detection switch 25, the count switch 26, the special winning ball detection switch 28, and the normal symbol starting gate detection switch 27 are processed in this step. Next, the process proceeds to S13, where processing is performed, and then S
The process proceeds to S14, where the normal symbol process process is performed, the process proceeds to S15, the sound process is performed, and the process proceeds to S16, where the information output process is performed.

Next, the process proceeds to S17, where a process of adding "1" to the reset counter is performed. Next, the process proceeds to S18, where it is determined whether or not the reset counter is "2". If so, a process of clearing the reset counter, that is, setting the reset counter to "0" is performed in S19. On the other hand, if the reset counter is not "2", the process of FIG.
Proceeding to S20 shown in (b), a display symbol random update process is performed.

As a result, the value of the reset counter changes to 0 or 1 every time a periodic reset signal is input from the periodic reset circuit 34 every 2 msec. As described with reference to FIG. 6, this is a process performed to transmit command data for display control once for a plurality of interrupts, and by changing the upper limit value of the reset counter (S18). By changing the numerical value of (1), the state of once for every two interrupts can be changed to once for every three interrupts and the like.

FIG. 8 is a flowchart showing a subroutine program of the display control processing shown in S9 of FIG. 7A. At S21, it is determined whether or not the value of the above-described reset counter is "0". If the value is "1", the subroutine program is terminated as it is.
On the other hand, if the value of the reset counter is "0", the process proceeds to S22, where the previous command data CD0-CD
7 and whether the contents of the current command data CD0 to CD7 match, and if they match, this subroutine program ends. A specific example of the case where the contents of the previous command data and the current command data match is, for example, a case where a demonstration screen (a demonstration screen) before the execution of the game is displayed on the variable display device 1. When it is not necessary to change and output the command data, when the symbol is stopped and displayed on the variable display device 1, or the number of executions of the repetition continuation control of the variable winning ball device 4 during the big hit control, that is, the number of rounds is displayed. And so on.

On the other hand, the command data D0 to be transmitted this time
If D7 is new command data and does not completely match the previous command data, the process proceeds to S23, where processing for outputting a command corresponding to the value of the transmission counter is performed. This transmission counter is a counter for counting each command data consisting of 0 to 7 shown in FIG. 6, and is for counting which command CD is currently being transmitted. This transmission counter is S31
Is cleared to “0” and becomes “1” by S29.
It is incremented and updated.

The process advances to S24 to determine whether or not the value of the current transmission counter is "7". If the value is not "7", the process advances to S25 to update the checksum.
The display control command signal is composed of data of seven blocks CD0 to CD6.
6 is the data in which the command data of 6 are added, a 1's complement is taken, and the most significant bit (7th bit) is masked with 0,
The CD 7 is transmitted as a checksum to the display control microcomputer. In S25, a process of updating the checksum and calculating the checksum is performed.

On the other hand, when the transmission counter is “7”,
Since the command output in S23 is CD7 and the checksum data itself, the checksum update processing in S25 is not performed.

Next, the flow advances to S26, where the INT signal is set to 3.9 μm.
m is output, the process proceeds to S27, and it is determined whether 68.4 μs has elapsed from the command output.
Wait for the time to elapse. After that, the process proceeds to S28, and a process of stopping the command output process in S23 is performed. Next, the process proceeds to S29, where a process of adding "1" to the transmission counter is performed, and the process proceeds to S32, where it is determined whether or not the transmission counter is "8". If the transmission counter has not yet reached "8", Proceed to S23, and from S23
The process of S30 is repeatedly executed. Then, when the transmission counter reaches "8", YES is determined in S30, and the transmission counter is cleared to "0" in S31.
And a process of clearing the checksum is performed. As described above, in S22, it is determined whether or not the command data to be transmitted this time has the same content as the previous command data. If the same, the command data is again transmitted to the display control microcomputer. , And in such a case, the command data transmission processing after S23 is not performed. As a result, unnecessary command data output is skipped, and the command data output interval is irregular.

FIG. 9 is a flowchart showing a subroutine program of the output data setting process shown in S7 of FIG. 7A. This subroutine program converts each output data into an output format and sets it.
First, in S32, a process of adding and updating the general-purpose timer by “1” is performed. Next, the process proceeds to S33, in which processing for clearing unnecessary data of the port B / C is performed, and then the process proceeds to S34,
Processing for setting data to port B is performed, and then S3
The process proceeds to S5 to calculate and set the data of the port C, and then proceeds to S36 to determine whether the probability is not fluctuating. S3 if the probability is not changing
The process proceeds to step S9, but if the probability is changing, the process proceeds to step S37.
A determination is made as to whether a big hit is in progress. If a big hit is in progress, the process proceeds to S39.
Proceeding to 38, a process of setting the lamp control data during the probability fluctuation is performed.

Next, in S39, a process of setting data to the port C is performed, and the flow advances to S40 to determine whether or not the specific area switch has not been won. If the hit ball that has entered the variable winning ball device 4 wins in the specific winning area (V pocket) and is detected by the specific winning ball detection switch 8, a NO determination is made in S40, and in S41,
The state where the V display LED is set and the fact that the V prize has been won is displayed. On the other hand, if the pachinko ball has not yet won the specific winning area, the process proceeds to S42 without performing the V display LED setting process, and the number display LE
It is determined whether or not display is to be performed by D13. If display is to be performed by the number display LED 13, digit 4 output data is set by DG4 in S43.
(See FIG. 2) becomes a high level state.

On the other hand, when the display by the number display LED 13 is not performed, the process proceeds to S44 and the two storage display LEDs
It is determined whether display is to be performed by at least one of the fourteen. If not, the process directly proceeds to step S46. If not, the process proceeds to step S45, where digit 3 output data is set and DG3 (see FIG. 2) Becomes a high level state.

Next, in S46, it is determined whether or not display is to be performed by the left side LED 22b. If not, the process directly proceeds to S48. If not, the process proceeds to S47 to set digit 5 output data. DG5
(See FIG. 2) becomes a high level state. Next, in S48, it is determined whether or not display is to be performed by the left side LED 22a. If not, the process directly proceeds to S50. If not, the process proceeds to S49, where the digit 6 output data is set and DG6 ( 2) becomes a high level state.

Then, the program proceeds to S50, in which a process for calculating the normal symbol display data is performed. In S51, it is determined whether or not an error is occurring, and an illegal act such as pulling out of a 10-count detection switch is performed. If it is detected, the process proceeds to S52, where the error display address is set. If it is determined that the error is not occurring, the process proceeds to S53 without setting the error display address,
A determination is made as to whether or not display is to be performed by the normal symbol variable display device 7. When the display by the ordinary symbol variable display device 7 is not performed, the subroutine program is terminated. When the display is performed, however, the process proceeds to S54, where the digit 1 output setting process is performed and the DG1 (see FIG. 2) is set to the high level state. Become.

As described above, the LED (light emitting diode)
L for displaying among 7, 11 to 14, 26a and 26b
Since only the digit output data corresponding to the ED is set, and the digit output data corresponding to the LED that does not perform display is not set, the output of the digit data is irregular.

FIG. 10 is a flowchart showing a subroutine program of the random update process shown in S11 of FIG. This subroutine program adds and updates a random counter WC RND1 for a big hit determination, a random counter WC RND2 for a normal symbol hit determination, and a random counter WC RNDL for a left scheduled stop symbol every 2 msec. It is. In addition, the variable display result of the variable display device 1 becomes a symbol of a slot, and when a big hit occurs, the high probability state described above is obtained depending on the type of the symbol constituting the slot, and therefore, the left scheduled stop The symbol determination random counter WC RNDL also functions as a probability variation random counter.

First, in step S55, a process of updating the left symbol and random fluctuation determination random counter WC RNDL is performed. In step S56, a process of adding "1" to the big hit determination random counter WC RND1 is performed, and then in step S57. To determine whether or not the big hit determination random counter is less than the maximum value. If the value is less than the maximum value, the process proceeds to S59. If the value has reached the maximum value, the process proceeds to S58, and the big hit determination random counter 1
Is cleared to "0". Next, S59
Then, a process of setting the random counter 1 for jackpot determination is performed, and then, in S60, a process of updating the random symbol WC RND2 for ordinary symbol determination is performed.

Next, in the EFF6H, a process of setting a random counter for big hit determination is performed.
, The random symbol WC RND for normal symbol determination
2 is updated.

FIG. 11 is a flowchart showing a subroutine program of the switch process shown in S21 of FIG. 7A. This subroutine program performs a logic determination process for each switch.
Thus, it is determined whether or not the probability is being set. It is determined in S61 whether or not the probability of the jackpot occurrence probability (setting 1, setting 2, setting 3) is being set by the operating means that can be operated only by the staff at the above-mentioned amusement arcade. If it is determined, the process proceeds to S62, and it is determined whether an error is occurring. If the illegal winning warning flag set when a 10 count error or the like occurs is not set, it is determined that no error has occurred, and the flow advances to S63 to perform the first-class start-up opening switch process, ie, the winning of the start winning ball detection switch 25. Perform judgment processing,
Next, the process proceeds to S64, in which a normal symbol switch process, that is, a winning determination process of the normal symbol start gate detection switch 27 is performed, and then the process proceeds to S65. On the other hand, if it is determined that the probability is being set or if it is determined that there is an error, the process proceeds to S65 without performing the processes of S63 and S64, and the winning determination process of the count switch 26 is performed.
Next, in S66, a winning process of the specific winning ball detection switch 8 is performed. In the case of an error in which the warning flag is set as described above, the switch check process is not performed even if a ball is hit in the starting winning opening 3 or the ordinary symbol starting gate 6, so that the variable display device 1 or Usually, the symbol variable display device 7 is not variably displayed.

FIG. 12 is a flowchart showing a subroutine program of the first type start-up switch processing shown in S63 of FIG. This subroutine program
The first type start port switch, that is, the switch of the start winning ball detection switch 25 is determined to win, and a random storage process is executed. First, in S67, a switch check process of the start winning detection switch 25 is performed.
At step S8, it is determined whether or not the switch is turned off as a result of the check processing. If the switch is turned off, the subroutine program is terminated as it is. A process of adding and updating the counter by “1” is performed, and then the process proceeds to S70,
A process of adding and updating the electric accessory winning counter by “1” is performed. The electric accessory is a variable winning ball device constituting the starting winning opening 3 (see FIG. 1), and the starting winning memory is performed by the electric accessory winning counter.

Next, in S71, it is determined whether or not the prize memory is equal to or more than the maximum value. If the count value of the electric accessory prize counter is equal to or more than the maximum value "4", it is determined. The subroutine program ends as it is, but if not, the process proceeds to S72, where a random storage bank is calculated, and in S73, a process of storing the extracted value (random number) of WC RND1 in the calculated storage bank is performed. . The WC RND1 is extracted when the detection signal of the start winning ball detection switch 25 is input, and stores the extracted value (random number) corresponding to the start winning memory associated with the detection signal of the starting winning ball detection switch. Because In addition, the starting prize memory can store up to “4” in chronological order, and the extracted value (random number) of WC RND1
Are also configured to be able to store four items in order from the oldest. The storage location is calculated in S72, and the extracted value (random number) is stored in the calculated storage location (S7).
3). Then, in the calculated storage bank,
Random counter WC RND for determining the planned left stop symbol
The extracted value (random number) of L is also stored. Next, proceed to S75,
The winning storage counter is updated by adding “1”. The start prize storage is performed by the prize storage counter.

FIG. 13 is a flowchart showing the control operation of the control circuit shown in FIG.
9 is a flowchart of a subroutine program showing input processing of .about.CD7. First, the interrupt signal is set to O by SA1.
It is determined whether or not N has been reached. If it has not been turned ON, the subroutine program ends. On the other hand, from the microcomputer for game control,
If T has been transferred, a determination of YES is made by SA1 and the process proceeds to SA2, where it is determined whether or not the input counter is "7". This input counter is for counting the transmitted command data,
The number of command data transmitted at the present time is counted. And cleared by SA8, "0"
And “1” is added each time the processing of SA4 is executed.

If the transmitted command data has not yet reached "7", that is, has not reached the checksum data, a determination of NO is made by SA2 and the process proceeds to SA3, where the inputted command data is stored in the spare storage area. Is performed. This spare storage area is an area for temporarily storing transmitted command data. Next, the process proceeds to SA4, where the input counter is incremented by “1”.

On the other hand, if the input counter has reached "7", that is, if the transmitted command data is the checksum data of CD7, a determination of YES is made by SA2 and the process proceeds to SA5 to store the spare storage area. Processing for calculating a data checksum is performed. That is, a process is performed in which the command data of CD0 to CD6 stored in the spare storage area are added, a 1's complement is taken, and the most significant bit (seventh bit) is masked with 0. Next, the process proceeds to SA6, where it is determined whether the checksum of the calculation result matches the checksum received this time, that is, CD7. In the normal case, the process proceeds to SA7 because they match, and the storage data CD0 to
Processing for storing the CD 7 in the command data storage area is performed. The command data storage area is defined as the command data CD0 determined to be correct as a result of the checksum.
This is an area for storing the CD 6 properly, and the display control microcomputer performs a display control operation based on the command data stored in this area.

On the other hand, if the command data is out of order due to noise or the like during the transmission of the command data, the SA
A determination of NO is made in step 6 and the process proceeds to SA8 without performing the process of SA7, where the data in the spare storage area is cleared, and the input counter is cleared to "0". As a result, when command data that is out of order due to noise or the like is received, the out-of-order command data that is received and stored in the spare storage area is cleared and discarded, and is normally stored in the command data storage area. Never. As a result, the display control microcomputer continues the display control of the variable display device based on the correct command data transmitted last time.

Next, features, modifications, and the like of the above-described embodiment will be enumerated below. (1) Although the variable display device 1 has been described as being composed of a liquid crystal display device, a device using a CRT, electroluminescence, light emitting diode, or the like may be used instead. It may be. The first state of the variable prize ball device 4 is the open / close plate 9
May be repeatedly opened and closed, and the second state of the variable prize ball device 4 may be a state in which hitting is possible but difficult to win.

(2) R provided in the basic circuit 30
The OM constitutes a program storage means for storing a control program. The CPU provided in the basic circuit 30 constitutes a control center means that operates according to the program stored in the program storage means. The computer for game control shown in FIG. 2 performs the process of executing the control program from the beginning to the end within a predetermined period (within the input period of the reset signal from the periodic reset circuit 34), and performs the process. The game state of the gaming machine is controlled by repeating the above-described processing every predetermined period. The periodic reset circuit 34 constitutes periodic reset means for periodically resetting the control center means. The control center means performs a process of executing the control program from the beginning to the end within a reset cycle by the periodic reset means, and controls the game state of the gaming machine by repeating the process for each reset cycle. I do. As described with reference to FIG. 6, the game control computer including the control circuit shown in FIG. 2 transmits the display control command data (display control command signal) within a regular reset cycle of the regular reset means. Send it out.

Further, the computer for game control includes:
A necessity determining means (S22) for determining whether or not to output an output signal (command signal for display control) every time the reset by the periodic reset means is performed a plurality of times is included. That is,
When the content of command data (command signal for display control) is changed, the computer for game control outputs an output signal (command signal for display control) once for each of a plurality of resets by the periodic reset means. ) Is sent. The game control computer includes a display control command signal (IN
T, CD0 to 7) and transmission timing control means (S26 to S28) for controlling the transmission timing.

(3) As described above, in the present embodiment, if the command data to be transmitted this time has the same content as the previous command data, the command data is not transmitted. Instead, command data having the same content may be transmitted a predetermined number of times (for example, twice). By doing so, the display control microcomputer side discards the received command data even if it determines that the command data is out of order as a result of the checksum and discards the received command data.
For example, after 4 msec, since the same command data is transmitted again, there is an advantage that the transmitted command data can be received and the variable display control can be performed based thereon.
