2. Description of the Related Art Conventionally, in this type of gaming machine, control of a gaming state and control of an effect performed in relation to this gaming state have been performed by one control board. However, since the memory capacity of the memory mounted on the control board has a certain limit, it has been extremely difficult to diversify the game and the diversification of the effects.

Therefore, a sub control board separate from the main control board for controlling the game state is provided, and the main control board sends a production control command to the sub control board.
Many game machines have been put into practical use in which the sub control board receives the effect control command to control the effect according to the game state controlled by the main control board.

Further, in this main gaming machine, the information transmitted to the sub control board is inconveniently transmitted in synchronization with the control state of the main control board (for example, in the case of a slot machine). Delays the information transmitted to the sub-control board in order to avoid the inconvenience that the push assist effect is performed by transmitting the command in synchronization with the rotation state of the reel. It is generally sent.

In a gaming machine having a main control board and a sub-control board separately as described above, when the power-off is backed up, the main control board monitors the power supply status. When the power supply condition becomes less than a certain voltage and the power-off condition is satisfied, the game state backup process is performed and the sub-control board is requested to back up the production state accordingly. Send a backup command to that effect,
In response to the reception of this backup command, the sub control board is performing backup processing of the effect state. However, since the backup command is also transmitted with a delay as described above, the drive power may drop before the main control board completes the transmission of the backup command, and the operation may stop. However, there is a problem that the sub control board cannot receive the backup command at the time of power off and cannot perform the backup process.

The present invention has been made by paying attention to such a problem, and even when the backup request from the main control board is delayed and transmitted, the sub control board can be surely backed up. The purpose is to provide a machine.

Then, a predetermined number of medals corresponding to the winning content are paid out to the player as credits, and the credit number displayed on the credit display unit 31 is added and updated. When the number of credits reaches the upper limit, medals are paid out directly from the medal payout holes. The number of payouts of these medals is displayed on the payout display section 33.

In addition, particularly when a combination of predetermined special symbols is displayed and a big hit (special prize) is won, medals are paid out, and
In addition to the normal game state, a special game state that is advantageous for the player, that is, a large amount of medals is generated, and a big bonus (hereinafter referred to as BB) or a regular bonus (hereinafter referred to as RB) as described later occurs. The game value is given to the player.

The "gaming value" given to the player by winning in this way is not limited to the valuable value such as medals and credits, but is given to the player when the jackpot is won as described above. It includes all the benefits related to the game such as BB and RB that are granted to the game.

In the slot machine 1 of this embodiment, for example, "BAR" is displayed on any of the pay lines L1, L2, L2 ', L3, L3' which are activated according to the bet number.
If the symbols "-BAR-BAR" are aligned, it is a big hit RB
In this case, 15 coins are paid out in consideration of the fact that the "BAR-BAR-BAR" symbols are aligned, and the RB (regular bonus) state, which is a game state advantageous to the player, is obtained. The regular bonus game that is generated and described below is given to the player as a game value. In this RB, a Jac game in which a predetermined number of medals are paid out due to the alignment of plum symbols with a high probability of winning a Jac prize is provided at a maximum of 12 times, and this Jac game is 1 times.
The game is executed twice, or when the Jac prize is won eight times before the Jac game reaches twelve times, or when either condition is satisfied, the process ends. Therefore, the player can get up to eight Jac prize winning opportunities during the 12 Jac games.

On the other hand, the activated pay lines L1 and L

If you have "Black 7" or "White 7-White 7-White 7", you have won the big hit BB (Big Bonus).
For example, 15 medals are paid out as a consideration for having the symbols of "black 7-black 7-black 7" or "white 7-white 7-white 7", and in a special game state advantageous to the player. A certain BB (big bonus) state occurs, and a small winning game described below is given to the player as a game value. More specifically, in this BB, there is a high probability that the small winning symbols (watermelons, bells, plums in the embodiment) are aligned with a high probability and a small winning combination accompanied by the payout of a predetermined number of medals is highly likely. A small winning game that is generated is provided at most 30 times, and when the JacIn prize is won with a complete set of plum symbols until the small winning game is executed 30 times, it is a special game state. The above-mentioned RB state occurs and a regular bonus game is provided. This RB has a predetermined maximum number of times that it can occur in the BB, and in the present embodiment, it can occur up to three times. Then, this BB is provided when RBs are provided 3 times when the small winning combination game is executed and ended, or before the small winning combination game is executed 30 times.
Among the cases where the RB for the second time is completed, the process is completed when at least one of the conditions is satisfied.

Further, in the case of a normal game state (base game) other than the special game state, when a predetermined prize is established in line on one activated line in which symbols of the same kind are activated, , A predetermined number of medals predetermined according to the type of the symbol are given to the player. The "cherry" drawn on each reel 51L, 51C, 51R
The symbol is a mark called a single symbol, and when this single symbol is stopped and displayed on one effective line, it is 2
The number of medals is given to the player. If there are multiple activated lines activated according to the number of bets, and if the combination of symbols for which medals are paid out is simultaneously established on multiple winning lines as described above, each winning line is As a general rule, medals corresponding to the total number of medals given by the combination of symbols on the line are given. However, since the upper limit of the medals to be given to the player in one game is set to 15, the 16th and subsequent medals are invalidated when the number exceeds 15.

In this embodiment, black 7-black 7-black 7 (black 7 award), white 7-white 7-white 7 in the normal game state.
(White 7 Award), BAR-BAR-BAR (BAR Award), Watermelon-Watermelon-Watermelon (Watermelon Award), Cherry (Cherry Award), Bell-Bell-Bell (Bell Award), or Plum-

The small role notification lamps 140a to 140c and the reel lamp 55 do not affect the progress of the game itself even if they do not function as compared with various indicators controlled by the game control board 200. With a focus on the effect of production, it can be called, so to speak, a "production device (peripheral device for production in the present invention)". Therefore, even if the production control board 201 fails, the player is not provided with a disadvantageous situation, and the control load of the control unit 210 is reduced.

Returning to FIG. 5, the detection signal of the start switch 102 is sent to the control unit 210 via the switch circuit 215.
And the sampling circuit 222. The control unit 210 receives the detection signal of the start switch 102 and outputs a reel control signal via the motor circuit 216. This reel control signal is sent to the reel relay board 2
It is input to the reel motors 54L, 54C, 54R provided separately for the respective reels 51L, 51C, 51R via 03. Further, the reel control signal is output to the outside of the slot machine 1 via the reel relay board 203 and the external output board 205.

As a result, each reel 51L, 51C, 5
1R begins to fluctuate. In addition, the reel control signal transmission path is the reel motor 54 in the reel relay board 203.
The reel control signal is branched to the L, 54C, 54R side and the external output board 205 side, and the reel control signal output to the external output board 205 side is output from the external output board 205 to the slot machine 1.
Is also output to outside. In this way, the external output board 20
The reel control signal output from 5 is not a signal processed for external output, but reel motors 54L, 54C, 5
It is the signal itself for controlling the drive of the 4R.

On the other hand, the sampling circuit 222 samples one random number from the random number generation circuit 221 at the timing when the detection signal of the start switch 102 is input,
The random number is delivered to the CPU 211. The CPU 211 is
By referring to the sampled random numbers and the winning determination table stored in the ROM 213, it is determined whether or not the winning is permitted for each winning combination, and the RAM 212 stores the determination result. As a result, the internal lottery process described later is performed at a timing substantially equal to the timing at which the start operation is performed, and it is determined whether or not the winning combination is won. After that, the control unit 210 controls the reels according to the winning result for each winning combination.

Further, each stop switch 103L, 10L
The stop switch signals output from 3C and 103R are transmitted through a signal path that reciprocates between the game control board 200, the reel relay board 203, and the external output board 205, and then input to the switch circuit 215 of the game control board 200. . Furthermore, the stop switches 103L, 103C,
The stop switch signal output from 103R is directly
It is configured to be output to the outside via the external output board 205.

Upon receiving the stop switch signal, the control unit 210 receives the stop switch signal from the reel motors 54L, 54C, 54R via the motor circuit 216.
And outputs a reel control signal for stopping. This reel control signal is supplied to the reel motors 54L, 54C, 54R.
And is output to the outside of the slot machine 1 via the external output board 205.

The signal output from the external output board 205 can be used, for example, when a third party organization performs a type test. In this type test, for example, it is confirmed whether or not each reel 51L, 51C, 51R corresponding to each stop button 40L, 40C, 40R is stopped within 190 ms after the operation of each stop button 40L, 40C, 40R. In the case of this slot machine 1, since the stop switch signals output from the stop switches 103L, 103C, 103R are directly output from the external output board 205, the stop buttons 40L, 40C, 4
The timing when the 0R is operated can be accurately grasped outside the slot machine. Similarly, since the reel control signal output from the motor circuit 216 is directly output from the external output board 205, the start and stop timings of the reels 51L, 51C, and 51R can be accurately grasped outside the slot machine. Therefore, by using the signal output from the external output board 205, “each stop button 40L, 4L
Each reel 51 corresponding to each stop button 40L, 40C, 40R within 190 ms from the operation of 0C, 40R
An accurate test result can be obtained when the "test for whether L, 51C, 51R stops" is performed. In addition, “a configuration in which the control unit 210 of the game control board 200 once receives the signal and then outputs the signal to the external output board 205”
In such a case, there is a possibility that a fraud such as processing and outputting a signal is made on the game control board 200 side, but according to the present embodiment, such fraud can also be prevented.

In addition, the DC voltage of + 24V is supplied to the game control board 200 and is used as a drive power source for the reel motors 54L, 54C, 54R and the passage switching solenoid 107.
Further, + 24V DC voltage is supplied to the production control board 201 via the game control board 200, and is used as a drive power source for a lamp, a speaker, or a fluorescent lamp which is directly or indirectly connected to the production control board 201. It

FIG. 8 shows the CP in the game control board 200.
It is a circuit diagram showing an example of 1 composition around U211. As shown in FIG. 8, + 8V output from the power supply board 202 is DC
-Supplied to the DC converter 223. The DC-DC converter 223 generates + 5V to generate the CPU 211, the RAM 212, and a power supply monitoring IC as a power cutoff determination unit.
To 224. This + 5V is used as a driving power source for these devices. Further, + 5V generated by the DC-DC converter 223 is output to the effect control board 201 and used as a drive power source for each device of the effect control board 201 as described later.

The + 5V line from the DC-DC converter 223 is branched to form a main backup + 5V line. A large-capacity capacitor 226 is connected between the main backup + 5V line and the ground level. The condenser 226 is the slot machine 1
When the power supply to the RAM 212 is cut off, it serves as a backup power supply that supplies power to the RAM 212 so that the storage state of the backup RAM area can be maintained. Also,
A backflow prevention diode 225 is inserted between the + 5V line and the main backup + 5V line. still,
As a backup power source, a battery or the like that can be charged from a + 5V power source may be used.

The power supply monitoring IC 224 is the power supply board 202.
The voltage of + 8V output from, that is, the device of the game control board 200, especially the CPU 21 that controls each part
The occurrence of power failure is detected by introducing the voltage which is the source of the driving power source of No. 1 and monitoring the + 8V voltage. In this embodiment, the voltage drop signal is output when the + 8V voltage becomes equal to or lower than a predetermined value. This voltage drop signal is sent to the CPU 2
11 is input to the non-maskable interrupt terminal (NMI terminal). That is, the CPU 211 uses the power supply monitoring IC 224.
It is possible to confirm the occurrence of power failure by the interrupt processing based on the input of the voltage drop signal from.

The voltage for the power monitoring IC 224 to detect the power failure is higher than the operating voltage of the CPU 211 at the normal time, and in this embodiment, the power failure occurs when the voltage drops to + 7.2V. To detect. Further, the power supply monitoring IC 224 has a voltage higher than a voltage (+ 5V in this embodiment) for driving the CPU 211, that is, DC.
It is configured to monitor the voltage of + 8V supplied to the −DC converter 223, and the monitoring range can be expanded with respect to the voltage required by the CPU 211, and more precise monitoring can be performed.

Further, in this embodiment, the CPU 211, RA
The M212 and the power supply monitoring IC 224 are normally driven by a power supply voltage of +5 V, and at the same time, the power supply monitoring IC2
24 outputs a voltage drop signal when it drops to + 7.2V which is a voltage higher than + 5V for driving each of these devices, and remains + 5V for a while after the occurrence of power failure is detected. Since the voltage is supplied to the device such as the CPU 211, it is possible to sufficiently secure the time necessary for the CPU 211 to perform the main power interruption interrupt process described later based on the input of the voltage drop signal.

Further, in this embodiment, the power supply monitoring IC 22 is used.
4 is a DC that is a source of the drive voltage of the CPU 211, that is, DC in order to generate +5 V that drives the CPU 211.
The + 8V voltage supplied to the −DC converter 223 is monitored, and a stable voltage is monitored as compared with a drive voltage that easily fluctuates depending on the driving status of each device. It is possible to prevent malfunctions such as the occurrence of power failure due to a large voltage drop, and a main power interruption interrupt process to be described later being performed.

The present invention is not limited to this, and is a source of a power supply voltage for driving game peripheral devices such as switches, sensors, lamps, and displays connected to the game control board 200. A voltage, for example, the voltage supplied to the DC-DC converter 303 may be introduced and monitored to generate + 8V, + 12V, + 24V for driving these gaming peripherals, whereby
Depending on the driving situation of these gaming peripherals, a stable voltage will be monitored compared to the driving voltage that easily goes up and down, so it is determined whether power is cut off due to a temporary voltage drop, and the main power failure described later. It is possible to prevent malfunctions such as time interruption processing being performed.

FIG. 9 shows the CP in the effect control board 201.
It is a circuit diagram showing an example of composition of the circumference of U231. As shown in FIG. 9, the game control board 20 is provided on the effect control board 201.
+ 5V generated by the DC-DC converter 223 of 0
Is supplied and used as a driving power source for the CPU 231 and the RAM 232.

The + 5V line from the game control board 200 is branched to form a sub backup + 5V line. A large-capacity capacitor 240 is connected between the sub backup + 5V line and the ground level. The capacitor 240 serves as a backup power supply that supplies power to the RAM 232 so that the storage state of the backup RAM area can be maintained when the power supply to the slot machine 1 is cut off. Further, a diode 239 for preventing backflow is inserted between the + 5V line and the sub backup + 5V line. A battery or the like that can be charged from a + 5V power source may be used as the backup power source.

Further, in this embodiment, the power supply monitoring IC 22 is used.
Even after the occurrence of power failure is detected by 4, the supply of + 5V voltage is maintained for a while for each device of the game control board 200 and each device of the effect control board 201. Specifically, the voltage supplied to the DC-DC converter 223 of the game control board 200 is the power supply monitoring IC 22.
4 drops to + 7.2V that detects the occurrence of power failure, and then drops to + 5V or less required to generate a voltage for driving each device of the game control board 200 and each device of the production control board 201. Until the voltage drop time elapses, the + 5V voltage output from the DC-DC converter 223 is held, and each device of the game control board 200 and each device of the effect control board 201 are in an operable state.

This voltage drop time, the game control board 200
The CPU 211 receives a voltage drop signal from the power supply monitoring IC 224 and then has sufficient time to complete the main power interruption interrupt process described later. That is, even if the power is cut off, the drive voltage of each device in the game control board 200 is held until the main power interruption interrupt processing performed by the CPU 211 is completed.

Further, the voltage drop time is the game control board 20.
After the CPU 211 of 0 receives the voltage drop signal from the power monitoring IC 224, the CPU 2 of the effect control board 201
It is set to a time sufficient for 31 to complete the sub-backup process at the time of power failure described later. In other words, even if the power is cut off, the drive voltage of each device in the effect control board 201 is maintained until the CPU 231 completes the power failure sub-backup process.

In the case of this embodiment, the game control board 200
The time required for the CPU 211 to receive the voltage drop signal and complete the main power interruption interrupt processing is the transmission delay time (maximum of about 3 at the time of transmitting a power cut command described later).
7ms) is about 40ms, and the time required from the CPU 211 of the game control board 200 receiving the voltage drop signal until the CPU 231 of the effect control board 201 completes the sub-backup process at power failure, Approximately 56 ms even considering the above-mentioned transmission delay time (maximum of approximately 37 ms)
(Approximately 40 ms by the time the power-off command is received + approximately 16 ms by the time of power failure sub-backup processing), whereas the voltage drop time is approximately 100 ms. It should be noted that the present invention is not limited to this, and at least when the power is cut off, the drive voltage of each device in the game control board 200 is held until the main power interruption interrupt process performed by the CPU 211 is completed. It should be set at such a time.

Next, the game control board 20 in this embodiment.
Various control contents executed by the CPU 211 of the control unit 210 mounted on the 0 will be described below based on the flowcharts of FIGS. 10 to 15.

As shown in FIG. 10, when the power is turned on, it is first confirmed whether or not the setting key switch 82 is on (Sa1). That is, it is confirmed whether the power is turned on based on an operation for changing the set value or initializing the game state.

When the setting key switch 82 is on, the main initialization process as the game information initialization execution process for initializing the game state is executed (Sa
2) Then, a setting change process is executed that can change the setting value of the winning probability (Sa3).

In the main initialization process, as shown in FIG. 11, a process of clearing the register and the RAM 212 (Sb
After performing 1), an initialization command for instructing initialization of the effect state is set in the command table (Sb2),
A command sending process (Sb3) for sending the set initialization command to the effect control board 201 is performed, and a necessary initial value setting process (Sb4) is performed. As will be described in detail later, by transmitting this initialization command, the performance control board 2
The effect state controlled by 01 is also initialized. That is, the main initialization process also functions as an initialization command transmission process.

Further, in the command transmission process performed in Sb3, as shown in FIG. 13, the transmission delay time is 0 to 37 ms.
It is randomly selected from among the above and determined (Sd1), and when the determined transmission delay time elapses, the command set in the command table is transmitted to the effect control board 201 (Sd2, Sd3).

As will be described later, this command sending process is a process that is similarly executed when sending various commands capable of specifying the game state, and the effect control board 2
This is a process for transmitting a command to 01 with a predetermined delay.

In the setting change process, as shown in FIG.
The system waits in the detection waiting state of the setting switch 83 or the start switch 102 (Sc1, Sc3), and in this state, each time the setting button 67 is operated and the setting switch 83 is detected, the set value of the winning probability is changed by one. (Sc1, S
c2). Further, the start lever 38 is operated in the states of Sc1 and Sc3 and the start switch 102 is detected (Sc3), so that the set value is determined. Next, wait until the setting key switch 82 is turned off (Sc4),
When the setting key switch 82 is turned off, the process ends. In this way, the setting key switch 82 is turned on.
By turning on the power in this state, the winning probability setting can be changed. Also, when the power is turned on with the setting key switch 82 turned on, the game state is always initialized. Therefore, when simply initializing the game state, the power is turned on with the setting key switch on. After inputting, the process may be terminated without changing the setting value.

Returning to FIG. 10, when the setting key switch 82 is off at Sa1, it is confirmed whether or not it is at the time of recovery from a power failure (Sa4). Whether or not the power was restored from the power failure is confirmed by a power-off flag set when the power is turned off.

When the power is restored from the power failure, RA
A data check (parity check in this embodiment) of the backup RAM area in M212 is performed (Sa
5, Sa6). If the power is restored after an unexpected power failure, the main backup data must have been saved in the backup RAM area of the RAM 212.
The check result will be normal.

If the check result is normal, the RAM 21
The main backup data of the backup areas 1 to 3 in 2 is compared to confirm whether or not the correct data is backed up by whether at least two main backup data match (Sa7, Sa8).

If the comparison result is normal, all the registers are restored from the main backup data in the backup area in the RAM 212 (Sa9), the power-off flag is cleared (Sa10), and the process returns to the routine before power-off. That is, the game state when the power is cut off is restored.

If the data check result and the comparison result are not normal, the game state cannot be returned to the state when the power was cut off, so an error code indicating that the game state cannot be returned to the state before the power was cut off is displayed. Game count display unit 32
Is displayed and displayed to the outside (Sa11), and the same main initialization process as that executed in the step of Sa2 described above is executed (Sa12) to initialize the game state. Incidentally, if it is confirmed in Sa4 that the power is not restored, that is, if the power-off flag is not set, the main initialization process is executed (Sa12).

When the setting change process described above is completed or the main initialization process in step Sa12 is completed, the process shifts to a loop process for repeatedly executing the game control process (Sa13).

As shown in FIG. 14, in the game control processing, first, initial setting for preparing for the game start is executed (Se1).

Next, when the start lever 38 is pressed, a BET process for fixing the bet amount is executed (Se).
2). Specifically, one or more credits are used when waiting for medals or credits to be received, when one or more medals are inserted, or when one BET button 36a or MAXBET button 36b is pressed. When the start lever 38 is pressed, the bet number of medals is determined and the game is started. Further, when the replay is won in the previous game, the same number of bets as in the previous game is set, the pressing operation of the start lever 38 is possible, and the bet number is calculated when the start lever 38 is pressed. Is confirmed and the game starts.

It is to be noted that the maximum bet number (3BE in the present embodiment) until the start lever 38 is pressed.
When more medals are inserted from the state in which T) is set, the valuable value corresponding to the number of inserted medals is stored as a credit in the RAM 212, and this is displayed on the credit display unit 31.

Next, the start lever 3 at Se2
When the game is started by pressing 8, the internal lottery process is executed to determine whether or not to allow the winning of any of the above-mentioned prizes (BB, RB, and other small prizes which are small profits for the player). Yes (Se3). This internal lottery process is executed to determine whether or not to win any prize in a stage before all the reels 51L, 51C, 51R are stopped. That is, winning is allowed only when the internal winning flag corresponding to any prize won by this lottery is set. That is, the control unit 210 has a function as a pre-determination unit that determines whether or not to allow any prize to be won.

Next, when the internal lottery process of Se3 is completed, a reel rotation process for rotating each reel 51L, 51C, 51R is carried out (Se4). In this reel rotation process, the error check by the reference position check during the rotation of the reels 51L, 51C, 51R is confirmed at any time by a timer interruption every predetermined time. Also, all reels 5
When 1L, 51C, and 51R rotate, the pressing operation of the stop buttons 40L, 40C, and 40R is validated, the operation valid lamps 122L, 122C, and 122R are turned on, and the reel stop timer count is started.

Next, the stop button 40L by the player,
Whether the pressing operation of 40C, 40R is performed or each reel 51
L, 51C, 51R from the start of rotation, without pressing the stop button 40L, 40C, 40R by the player, 30 seconds which is a predetermined time has elapsed and the condition for displaying the symbol is satisfied. At this time, the stop flags of the reels 51L, 51C, 51R are set, and the operation valid lamps 122L, 122C, 122R corresponding to the stop buttons 40L, 40C, 40R that have been pressed based on the setting of the stop flags. Is turned off, and reel stop processing for stopping the rotation of the corresponding reels 51L, 51C, 51R is performed (Se5).

Further, in this embodiment, only when the internal winning flag corresponding to any prize is set by the above-mentioned internal lottery processing, the combination of symbols corresponding to the prize is displayed on the predetermined effective line. Stop control so that they are aligned,
Further, when the internal winning flag corresponding to any prize is not set, stop control is performed so that the combination of symbols corresponding to the prize is not finally aligned on the activated activated line. That is, unless any of the prizes is internally won by the internal lottery process, the prizes are not won, and the prizes are averagely generated during the repeated game.

Next, at Se5, all reels 51 are
When it is determined that the rotation of L, 51C, and 51R is stopped, the display content displayed on the variable display device 50 and Sa3 are displayed.
In step S6, the winning determination process is performed to determine the winning content by collating with the contents of the internal winning flag that has been set and the like (Se6). Further, particularly when it is determined that one of the prizes has been won, various settings corresponding to the winning contents are executed. As the setting contents, for example, there are settings such as the number of payout medals corresponding to the winning contents, the game state, and the re-play.

The processing based on the setting content set corresponding to the winning content determined in Se6 is executed (Se
7). Specifically, it executes the process of paying out the set number of medals and changing the gaming state (changing from the normal gaming state to the special gaming state, or from the special gaming state to the normal gaming state). To do.

As described above, in the game control processing, various controls according to the progress of the game are performed. In addition, in this game control process, various commands that can specify the game state at that time according to the progress of the game are given to the effect control board 20.
The process of transmitting to 1 is performed. These production control board 2
The various commands transmitted to 01 are transmitted by the command transmission process, similarly to the initialization command described above. These various commands are also transmitted with a delay of a predetermined period in the range of 0 to 37 ms.

In this way, various commands to the effect control board 201 are transmitted with a delay for a predetermined period, so that a command capable of specifying this game state is transmitted in synchronization with the game state controlled by the game control board 200. Inconvenience associated with that, for example, the symbol display state of the reels and the like are synchronously transmitted to the effect control board 201, and the timing for aligning a specific symbol or the like is informed, that is, so-called push-assist is executed. It is possible to prevent the occurrence of inconvenience due to the storage.

Further, in the present embodiment, the command transmission delay time in the command transmission processing is in the range of 0 to 37 ms in which the reel of the variable display device 50 moves by one symbol (about 36 ms in this embodiment) or more. Since it is variably determined by, it is possible to reliably prevent the symbol display state of the reels from being synchronously transmitted to the effect control board 201.

FIG. 15 is a flow chart showing a main power failure interrupt process as a main backup process executed in response to the NMI based on the voltage drop signal from the power supply monitoring IC 224. That is, the main power interruption interrupt process is a process executed when the + 8V power supply voltage supplied from the power supply board 202 to the game control board 200 becomes equal to or lower than a predetermined voltage of 7.2V due to the power failure. .

In the main power interruption interrupt process, first,
It is set to interrupt prohibition (Sf1). In the main power interruption interrupt process, a checksum generation process is performed to ensure that the data in the RAM 212 is saved. If another interrupt process is performed during that process, the voltage may drop to a voltage at which the CPU 211 cannot operate before the checksum generation process is completed. Is set so that no

Next, a power-off command for instructing the backup of the effect state due to the power-off is set in the command table (Sf2), and the command sending process for sending the set power-off command to the effect control board 201. (Sf3) is performed. The command sending process performed here is
The process is the same as the process shown in FIG. 13, the transmission delay time is determined in the range of 0 to 37 ms, and the power-off command is transmitted after the determined transmission delay time has elapsed.

Then, it is confirmed whether or not the power-off flag is already set (Sf4). If the power-off flag has already been set, the subsequent processing is not performed. As a result, it is possible to avoid the inconvenience that the NMI occurs and the main backup data is overwritten after the power-off flag is cleared before the power-off flag is cleared, that is, before the return of the game state is completed.

If the power-off flag is not set,
The following processing is executed.

First, all output ports are turned off (Sf5). Then, the contents of each register, that is, the main backup data as game information capable of specifying the game state at that time is the backup RAM of the RAM 212.
The data is stored in areas 1 to 3 (Sf6 to Sf8). At this time, R
The same main backup data is stored in the backup RAM areas 1 to 3 in the AM 212. This makes it possible to more reliably back up the gaming state at the time of power failure. Further, parity data is generated based on the data of the entire backup RAM area in the RAM 212 (Sf9), and the generated parity data is stored in the parity data storage area (Sf10). Then, the power-off flag is set (Sf11). As described above, this power-off flag is used when it is determined whether power is restored from a power failure when the power is turned on. Then
The RAM 212 is set in the access prohibited state (Sf12).
When the power supply voltage decreases, the levels of various signal lines may become unstable and the contents of the RAM 212 may be garbled. However, if the access to the RAM 212 is prohibited in this way, the backup RAM The data will not be corrupted. Then, a loop process is performed in which no process is performed. That is, the operation is stopped internally. Therefore, the CPU 211 surely stops operating when the power is turned off.
In the main power interruption interrupt processing of the present embodiment, the program is looped in the final part, but it may be configured to issue a halt (HALT) instruction.

Next, various control contents executed by the CPU 231 of the control unit 230 mounted on the effect control board in this embodiment will be described below with reference to the flowcharts of FIGS. 16 to 19.

As shown in FIG. 16, when the power is turned on, it is first confirmed whether or not backup data is stored (Sg1). Whether or not the backup data is stored is confirmed by whether or not the data is stored in the backup RAM area of the RAM 232.

When the backup data is stored, the system waits in the waiting state for receiving the initialization command transmitted from the game control board 200 until the command receiving waiting time elapses (Sg2, Sg3). The command reception waiting time is the CP of the game control board 200 after the power is turned on.
The time is sufficient to surely receive the initialization command transmitted to the production control board 201 when U211 executes the main initialization process.

If the initialization command is not received even after the command reception waiting time has elapsed, a data check (parity check in this embodiment) of the backup RAM area in the RAM 232 is performed (Sg4, Sg5). When the power is restored after an unexpected power failure, RAM232
Since the sub-backup data should have been saved in the backup RAM area of, the check result is normal.

If the check result is normal, the RAM 23
By comparing the sub backup data of the backup areas 1 to 3 in No. 2, it is confirmed whether or not the correct data is backed up by whether at least two sub backup data match (Sg6, Sg7).

If the comparison result is normal, all the registers are restored from the sub-backup data in the backup area in the RAM 232 (Sg8), and the routine before the power-off is returned. That is, it returns to the state of effect when the power is cut off.

If the data check result and the comparison result are not normal, the effect state cannot be returned to the state when the power was turned off. Therefore, a sub initialization process for initializing the effect state is executed (Sg9). ). In addition, when it is confirmed that the sub backup data is not stored in Sg1, or in Sg2 and Sg3, the game control board 200
When the initialization command is received from, that is, when the CPU 211 of the game control unit 210 instructs the initialization of the effect state, the sub initialization process is executed.

In the sub initialization process, as shown in FIG. 17, a process of clearing the register and the RAM 232 (Sh
After performing 1), necessary initial value setting processing (Sh2) is performed. Furthermore, the output state of various lamps, indicators, speakers, etc. controlled by the production control board 201 is set to the initial state (S
h3). That is, the output state of the production peripheral device is also initialized with the initialization of the register and the RAM 232.

When the sub-initialization process is completed, a loop process (Sg10 to Sg1) for executing an effect in accordance with the game state specified by the command received from the game control board 200.
Go to 3).

In this loop processing, the game control board 200
Waiting for reception of various commands transmitted from (Sg10), when a command is received from the game control board 200, it is confirmed whether the received command is a power off command (Sg11), power off If it is not a command, after performing a normal time sub-backup process that saves the effect state at that time as sub-backup data (Sg12), various lamps and indicators according to the game state specified by the received command, The output state of the production peripheral device such as a speaker is controlled, and production control processing (Sg13) for performing various productions is executed.

Further, in the loop processing of Sg10 to Sg13, when a power-off command transmitted from the game control board 200 due to the occurrence of power-off is received, a power failure for saving the effect state at that time as sub-backup data When sub backup processing is executed.

FIG. 18 is a flow chart showing a normal sub-backup process which is executed each time a command indicating a game state is received from the game control board 200.

In the normal sub-backup processing,
First, the prohibition of interruption is set (Si1). In the normal sub-backup process, a checksum generation process is performed to ensure the storage of data in the RAM 232. If another interrupt process is performed during that process, a power failure may occur before the checksum generation process is completed, and the voltage may drop to a voltage at which the CPU 231 cannot operate. First, settings are made so that other interrupts do not occur.

Next, the contents of each register, that is, the sub-backup data as effect information capable of specifying the effect state at that time is stored in the backup RAM areas 1 to 3 of the RAM 232 (Si2 to Si4). At this time, RA
The same sub backup data is stored in the backup RAM areas 1 to 3 of M232. This makes it possible to back up the effect state more reliably. Further, parity data is generated based on the data of the entire backup RAM area in the RAM 232 (S
i5), the generated parity data is stored in the parity data storage area (Si6). After that, the interruption prohibition is released and the process proceeds to the effect control process of Sg13.

FIG. 19 is a flow chart showing a power backup sub-backup process which is executed when the power-off command transmitted from the game control board 200 is received.

In the power failure sub-backup processing,
First, the interruption is set to be prohibited (Sj1). In the power failure sub-backup process, a checksum generation process is performed to ensure that the data in the RAM 232 is saved. If another interrupt process is performed during that process, the voltage may drop to a voltage at which the CPU 231 cannot operate before the checksum generation process is completed. Is set so that no

Next, all output ports are turned off (Sj2). Then, the contents of each register, that is, the sub-backup data as the effect information that can specify the effect state at that time is stored in the backup RAM of the RAM 232.
The data is stored in areas 1 to 3 (Sj3 to Sj5). At this time, R
The same sub backup data is stored in the backup RAM areas 1 to 3 of the AM 232. As a result, it becomes possible to more reliably back up the performance state during a power failure. Further, the parity data is generated based on the data of the entire backup RAM area in the RAM 232 (Sj6), and the generated parity data is stored in the parity data storage area (Sj7). Then RAM2
32 is set in the access prohibited state (Sj8). When the power supply voltage decreases, the levels of various signal lines may become unstable and the contents of the RAM 232 may be corrupted. However, if the access to the RAM 232 is prohibited in this way, the backup RAM The data will not be corrupted. Then, a loop process is performed in which no process is performed.
That is, the operation is stopped internally. Therefore, the CPU 231 surely stops operating when the power is turned off. Although the program is looped in the final part in the sub power interruption interrupt process of the present embodiment, it may be configured to issue a halt command.

As described above, in the slot machine 1 of the present embodiment, when the occurrence of power cutoff is detected, the game control board 200 operates until the transmission of the power cutoff command to the effect control board 201 is completed. Since the production control board 201 can reliably receive the power-off command and execute the sub-backup process during a power failure, the production control board 201 reliably backs up the production state. be able to.

Since the production state is backed up in the production control board 201, the game control board 200
In, there is no need to back up the information on the effect state, and the burden on the backup capacity of the game control board 200 can be greatly reduced.

Furthermore, after the power is turned on, the game control board 200
In the case of initializing the register or RAM 212 to initialize the game state, an initialization command is transmitted to the effect control board 201, and the effect control board 201 also initializes the register or RAM 232 to initialize the effect state. As a result, the consistency between the two can be achieved, and when the production control board 201 can return to the production state before the power is turned off after the power is turned on, the sub backup data stored in the RAM 232 is used.

The + 5V line from the DC-DC converter 921 is branched to form a main backup + 5V line. A large-capacity capacitor 923 is connected between the main backup + 5V line and the ground level. The condenser 923 is a pachinko machine 600.
When the power supply to the RAM is shut off, the RAM 655 serves as a backup power supply that supplies power so that the storage state of the backup RAM area can be maintained. Also,
A backflow prevention diode 922 is inserted between the + 5V line and the main backup + 5V line. still,
As a backup power source, a battery or the like that can be charged from a + 5V power source may be used.

The power supply monitoring IC 902 is a power supply board 910.
+ 8V voltage output from the main board 631
The voltage that is the source of the drive power source of the CPU 656 for controlling the devices, especially the respective units, is introduced, and the occurrence of power failure is detected by monitoring the + 8V voltage. In this embodiment, the voltage drop signal is output when the + 8V voltage becomes equal to or lower than a predetermined value. This voltage drop signal is input to the non-maskable interrupt terminal (NMI terminal) of the CPU 656. That is, the CPU 656 can confirm the occurrence of power failure by the interrupt processing based on the input of the voltage drop signal from the power monitoring IC 902.

The voltage for the power monitoring IC 902 to detect the power failure is higher than the operating voltage of the CPU 656 at the normal time, and in this embodiment, the power failure occurs when the voltage drops to + 7.2V. To detect. Further, the power supply monitoring IC 902 has a voltage higher than the voltage (+ 5V in this embodiment) for driving the CPU 656, that is, DC.
It is configured to monitor the voltage of + 8V supplied to the -DC converter 921, the monitoring range can be expanded with respect to the voltage required by the CPU 656, and more precise monitoring can be performed.

Also, in this embodiment, the CPU 656 and RA
The M655 and the power supply monitoring IC 902 are normally driven by a power supply voltage of +5 V, and at the same time, the power supply monitoring IC 9
02 outputs a voltage drop signal when it drops to + 7.2V, which is a voltage higher than + 5V that drives each of these devices, and remains + 5V for a while after the occurrence of power failure is detected. Since the voltage is supplied to the device such as the CPU 656, it is possible to secure a sufficient time required for the CPU 656 to perform the main power interruption interrupt process described later based on the input of the voltage drop signal.

Further, in this embodiment, the power source monitoring IC 90 is used.
2 is a DC that is the source of the drive voltage of the CPU 656, that is, DC in order to generate +5 V that drives the CPU 656.
The + 8V voltage supplied to the −DC converter 921 is monitored, and a stable voltage is monitored as compared with a drive voltage that easily fluctuates depending on the driving status of each device. It is possible to prevent malfunctions such as the occurrence of power failure due to a large voltage drop, and a main power interruption interrupt process to be described later being performed.

Note that the present invention is not limited to this, and a voltage which is a source of a power supply voltage for driving a game peripheral device such as a switch, a sensor, a lamp, and a display connected to the main board 631. , DC- for generating + 12V and + 21V for driving these gaming peripherals, for example
The voltage supplied to the DC converter 913 may be introduced and monitored, so that a stable voltage is monitored as compared with the drive voltage that easily rises and falls depending on the driving status of these gaming peripheral devices. Therefore, it is possible to prevent the malfunction such as the occurrence of the power interruption due to the temporary voltage drop is determined, and the below-described main power interruption interrupt processing is performed.

FIG. 25 is a block diagram showing the configuration around the CPU for power supply monitoring and power backup in the variable display control board 680, the sound control board 670, and the lamp control board 635. Since the configuration around the CPU for power supply monitoring and power supply backup in each of these control boards is almost the same, here, the variable display control board 680 is used.
Will be described as an example.

As shown in FIG. 25, the variable display control board 6
80 includes a DC-DC converter 902 on the main board 631.
The + 5V generated in the above is supplied and used as a driving power source for the CPU 681a and the RAM 681b.

Further, the + 5V line from the main board 631 is branched to form a sub-backup + 5V line. A large-capacity capacitor 925 is connected between the sub backup + 5V line and the ground level. The capacitor 925 serves as a backup power supply that supplies power to the RAM 681b so that the storage state of the backup RAM area can be maintained when the power supply to the pachinko machine 600 is cut off. Further, a backflow prevention diode 924 is inserted between the + 5V line and the sub-backup + 5V line. A battery or the like that can be charged from a + 5V power source may be used as the backup power source.

Further, in this embodiment, the power source monitoring IC 90 is used.
Even after the occurrence of power failure is detected by 2, the main board 63
Supply of + 5V voltage to each device of No. 1 and each device of the variable display control board 680, the sound control board 670, and the lamp control board 635 is maintained for a while. Specifically, after the voltage supplied to the DC-DC converter 921 of the main board 631 drops to +7.2 V at which the power supply monitoring IC 902 detects the occurrence of power failure, each device of the main board 631 and variable From the DC-DC converter 921 until the voltage drop time until the voltage drops to +5 V or less required to generate the voltage for driving the devices of the display control board 680, the sound control board 670, and the lamp control board 635, elapses. The output + 5V voltage is held, and each device of the main board 631 and each of the variable display control board 680, the sound control board 670, and the lamp control board 635 are brought into an operable state.

This voltage drop time is equal to CP of the main substrate 631.
It is set to a time sufficient for U656 to complete the main power interruption interrupt process described later after receiving the voltage drop signal from the power supply monitoring IC 224. That is, even if the power is cut off, the drive voltage of each device on the main substrate 631 is
It is held until the main power interruption interrupt process performed by the CPU 656 is completed.

Further, the voltage drop time is C of the main board 631.
After the PU 656 receives the voltage drop signal from the power supply monitoring IC 902, the CPUs 681 a and 67 of the variable display control board 680, the sound control board 670, and the lamp control board 635.
It is set to a time sufficient for 1a and 636a to complete the sub-backup process at the time of power failure described later. That is, even if the power is cut off, the drive voltage of each device on the variable display control board 680, the sound control board 670, and the lamp control board 635 is maintained until the power failure sub-backup processing performed by the CPUs 681a, 671a, 636a is completed. Will be retained.

In the case of this embodiment, the CP of the main substrate 631
The time required from the reception of the voltage drop signal by U656 to the completion of the main power interruption interrupt process is the transmission delay time (maximum of about 37 m when transmitting the power cut command described later).
s) is about 40 ms, and the main substrate 631
After the CPU 656 receives the voltage drop signal, the variable display control board 680, the sound control board 670, the lamp control board 6
The time required for the 35 CPUs 681a, 671a, 636a to complete the sub-backup process at the time of power failure is about 5 even if the above-mentioned sending delay time (about 37 ms at maximum) is taken into consideration.
6ms (Approximately 40ms before receiving the power-off command + About 16ms until the completion of sub-backup processing at power failure)
On the other hand, the voltage drop time is about 100 ms. The present invention is not limited to this,
It suffices if the drive voltage of each device on the main board 631 is set to such a time that it is held until the completion of the main power interruption interrupt process performed by the CPU 656, at least when the power is cut off.

Next, various control contents executed by the CPU 656 mounted on the main board 631 in this embodiment will be described below. Note that the control content of the CPU 656 is almost the same as the control content other than the game control processing (see FIGS. 10 to 13 and 15) among the control content performed by the CPU 211 of the above-described embodiment, and therefore will be briefly described here. .

When the power is turned on, the CPU 656 first turns on the power based on the operation for changing the set value or initializing the game state, that is, the reset switch 62.
Check if 9 is on. When the reset switch 629 is on, the main initialization process as the game information initialization execution process for initializing the game state is executed, and the setting change process that can change the set value of the jackpot probability is executed. To execute.

In the main initialization process, a command sending process for sending an initialization command to the variable display control board 680, the sound control board 670, and the lamp control board 635 is performed. By transmitting this initialization command, the variable display control board 68 is
The effect state controlled by 0, the sound control board 670, and the lamp control board 635 is also initialized.

In the present embodiment, the commands transmitted from the main board 631 to the variable display control board 680, the sound control board 670, and the lamp control board 635 are in the range of 0 to 37 ms as in the first embodiment. The data is transmitted after being delayed by the transmission delay time variably determined by.

When the power is turned on, the reset switch 62 is
If 9 is off, it is confirmed whether or not it was at the time of recovery from a power failure.

When the power is restored from the power failure, RA
The data of the backup RAM area in M655 is checked, and the main backup data of the backup areas 1 to 3 are compared to confirm whether or not the correct data is backed up by checking whether at least two main backup data match.

If these results are normal, the RAM 65
All registers are restored from the main backup data of the backup area in 5 and the routine before the power-off is returned. That is, the game state when the power is cut off is restored.

If the data check result and the comparison result are not normal, the game state cannot be returned to the state when the power was cut off, so the main initialization process is executed.
Initialize the game state. Even if it is confirmed that the power is not restored, the main initialization process is executed.

When the setting change process described above is completed, or when the main initialization process is completed, the random number value updating process used in the jackpot lottery described above and a timer executed every predetermined period (2 ms in this embodiment) are executed. Whether or not there is a timer interrupt flag set by the interrupt process is confirmed, and when the timer interrupt flag is set, the game control process and a loop process for repeatedly executing the process are performed.

[0246] Further, a power failure occurs and the power source monitoring IC 90
When the NMI based on the voltage drop signal from 2 is input, the main power interruption interrupt process is executed. In the main power interruption process, the variable display control board 680 and the sound control board 6
70, the lamp control board 635 is transmitted with a power-off command to instruct backup of the effect state due to power-off. This power-off command is also delayed and sent by the sending delay time like the initialization command and the command sent in the game control process described above. After transmitting this power-off command, the contents of each register, that is, the main backup data as game information capable of specifying the game state at that time is stored in the backup RAM areas 1 to 3 of the RAM 655 and the entire backup RAM area. Parity data is generated on the basis of the data and stored in the parity data storage area. At this time, the same main backup data is stored in the backup RAM areas 1 to 3. This makes it possible to more reliably back up the gaming state at the time of power failure.

Next, various control contents executed by the CPUs 681a, 671a and 636a mounted on the variable display control board 680, the sound control board 670 and the lamp control board 635 in this embodiment will be described below. In addition, these CPU6
The control contents of 81a, 671a, and 636a are almost the same as the control contents (FIGS. 16 to 19) performed by the CPU 231 of the above-described embodiment, and therefore will be briefly described here.

The CPUs 681a, 671a and 636a are
When the power is turned on, first, it is confirmed whether or not the backup data is saved. When the backup data is stored, the standby state is awaited for receiving the initialization command transmitted from the main board 631 until the command reception waiting time elapses.

When the initialization command is not received even after the command reception waiting time has elapsed, the RAMs 681b and 67
1b and 636b, the data of the backup RAM area is checked, the sub backup data of the backup areas 1 to 3 are compared, and it is confirmed whether or not the correct data is backed up by whether at least two sub backup data match. .

If these results are normal, the RAM 68
All the registers are restored from the sub-backup data in the backup areas 1b, 671b, 636b, and the routine returns to the routine before the power was cut off. That is, it returns to the state of effect when the power is cut off.

If the data check result and the comparison result are not normal, the production state cannot be returned to the state when the power was turned off, so the sub initialization process is executed to initialize the production state. Even when it is confirmed that the backup data is not saved, the sub initialization process is executed.

In the sub initialization process, the variable display control board 6
The output state of the display device, the lamp, the speaker, etc. controlled by the sound control board 80, the sound control board 670, and the lamp control board 635 is set to the initial state. That is, registers and RAMs 681b and 671
With the initialization of b and 636b, the output state of the production peripheral device is also initialized.

When the sub initialization process is completed, the main substrate 63
Command is received from the main board 631. Whenever a command is received from the main board 631, the normal state sub-backup process of saving the presentation state at that time as sub-backup data is executed, and then the received command is received. Depending on the more specified gaming state, the output state of the production peripheral devices such as various lamps, indicators, and speakers are controlled, and the process proceeds to loop processing for performing production control processing for performing various productions.

In addition, in this loop processing, when a power-off command transmitted from the main board 631 due to the occurrence of power-off is received, the effect state at that time is saved as sub-backup data. To execute.

In the normal sub-backup processing executed each time a command indicating the game state is received from the main board 631, the contents of each register, that is, the sub-backup data as the production information capable of specifying the production state at that time is stored. The parity data is stored in the backup RAM areas 1 to 3 of the RAMs 681b, 671b, 636b, and parity data is generated based on the data in the entire backup RAM area and stored in the parity data storage area. At this time, the same main backup data is stored in the backup RAM areas 1 to 3. This makes it possible to more reliably back up the gaming state at the time of power failure.

Further, in the power-off sub-backup process executed when the power-off command transmitted from the main board 631 is received in response to the power-off, the contents of each register, that is, the effect state at that time can be specified. Sub-backup data as the performance information is RAM 681b, 6
The data is stored in the backup RAM areas 1 to 3 of 71b and 636b, and parity data is generated based on the data of the entire backup RAM area and stored in the parity data storage area. At this time, backup RAM
The same main backup data is stored in areas 1 to 3. This makes it possible to more reliably back up the gaming state at the time of power failure. After that, access to the RAM is prohibited, and the process proceeds to a loop process in which nothing is executed.

As described above, in the pachinko machine 600 of this embodiment, when the occurrence of power failure is detected, the power cut command is transmitted to the variable display control board 680, the sound control board 670, and the lamp control board 635. The main board 631 is operatively energized until completion of the process, and the variable display control board 680, the sound control board 670, and the lamp control board 635 reliably receive the power-off command to perform the sub-backup processing at the time of power failure. Therefore, the variable display control board 680, the sound control board 670, and the lamp control board 635 can reliably back up the effect state.

Further, since the effect state is backed up in the variable display control board 680, the sound control board 670, and the lamp control board 635, it is not necessary to back up the effect state information in the main board 631. The burden of backup capacity can be greatly reduced.

Furthermore, when the register and RAM 655 are initialized on the main board 631 after the power is turned on to initialize the game state, the variable display control board 680 and the sound control board 67 are used.
0, the initialization command is transmitted to the lamp control board 635, the variable display control board 680, the sound control board 670,
The lamp control board 635 also has a register, a RAM 681b,
Since 671b and 636b are initialized to initialize the effect state, the consistency of each board can be achieved, and after the power is turned on, the variable display control board 680, the sound control board 670, and the lamp control board 635 are When it is possible to return to the effect state before the power is turned off, RAM 681b, 671
b, 636b, the variable display control board 680, the sound control board 670, and the lamp control board 6 can be returned to the effect state before the power is turned off based on the sub-backup data stored in
35 can be independently returned without receiving an instruction from the main board 631, and the variable display control board 680, the sound control board 670, and the lamp control board 635 can be returned without burdening the main board 631. .

Further, in the pachinko machine 600 of this embodiment, when the jackpot probability, that is, the payout rate is set, the main substrate 631 is subjected to the main initialization process, and the variable display is performed accordingly. An initialization command is transmitted to the control board 680, the sound control board 670, and the lamp control board 635, which causes the variable display control board 68.
0, the sound control board 670, and the lamp control board 635 are also subjected to the sub-initialization processing. Therefore, when the set value is changed, the main board 631 and the variable display control board 680, the sound control board 670, and the lamp control board 635 are changed. All of them can be returned to the initial state, and the consistency of each substrate can be achieved.

Further, in the pachinko machine 600 of this embodiment, when the operation for initializing the game state is performed, the main initialization process is performed on the main board 631 and the variable display control is performed accordingly. An initialization command is transmitted to the board 680, the sound control board 670, and the lamp control board 635, so that the variable display control board 680, the sound control board 670, and the lamp control board 635 are also subjected to sub-initialization processing. Therefore, when the game state initialization operation is performed, the main board 631 and the variable display control board 680, the sound control board 670, the lamp control board 635.
Can be returned to the initial state, and the consistency of each substrate can be achieved.

In the pachinko machine 600 of this embodiment, when the power is turned on, if the game state controlled by the main board 631 can be returned to the state before the power is turned off, the state before the power is turned off is automatically set. The game state can be restored, and it is not necessary to perform an extra operation, so that the game state can be easily restored.

Further, in the pachinko machine 600 of this embodiment, when the game state controlled by the main board 631 cannot be restored to the state before the power is turned off when the power is turned on, that effect is displayed as an error code in the variable display portion 609. Is displayed, it is possible to notify the outside that an error has occurred, and quick response is possible. In the present embodiment, the variable display unit 609 notifies the error, but the present invention is not limited to this.
The fact that an error has occurred may be displayed on another display, or the error may be notified by lighting a lamp or outputting a notification sound.

Further, in the pachinko machine 600 of this embodiment, when the sub-initialization processing is performed on the variable display control board 680, the sound control board 670, and the lamp control board 635, the registers and RAMs 681b, 671b, 63 are used.
6b is initialized and the variable display control board 6
80, the sound control board 670 and the lamp control board 635 control the output state of the display peripherals such as indicators, lamps, speakers, etc. so that the output state is also set to the initial state.
In 31, the initialization command is sent to the variable display control board 680,
Only by transmitting to the sound control board 670 and the lamp control board 635, the output state of the production peripheral device can be controlled to the initial state.

Further, in the pachinko machine 600 of this embodiment, each time the variable display control board 680, the sound control board 670, and the lamp control board 635 receive a command, which is production control information, from the main board 631, the current time point is displayed. A normal sub-backup process for saving the effect state is executed, and the variable display control board 680 and the sound control board 67 are used.
0, the backup of the effect state performed by the lamp control board 635 can be performed more reliably.

The present invention is not limited to this. For example, when a command indicating a specific game state is received, or when a command is received a predetermined number of times, the normal sub-backup process is performed. Is also good.

Further, in the main board 631 of the pachinko machine 600 of this embodiment, when it is determined that the power is cut off, the variable display control board 680, the sound control board 670,
After transmitting the power-off command to the lamp control board 635, the game state is backed up. By doing so, the variable display control board 680,
