Description

  The present invention relates to a game machine represented by a pachinko machine and a slot machine (pachislot).

  A gaming table represented by a pachinko machine is configured to obtain a predetermined profit by firing a ball from a launching device and entering a predetermined winning opening provided in a predetermined gaming area. Such a game machine is generally controlled by a microcomputer. Specifically, a program is stored in the ROM, and data that temporarily occurs under control and data that changes as the game progresses are stored in the RAM. For this reason, when the power is cut off due to a power failure or the like in the game table, the data in the RAM is lost, which causes a disadvantage to the player. For example, if a power interruption occurs during a jackpot game, the contents of the RAM will be cleared, so that even if restarted, the player cannot enjoy the benefits based on the jackpot.

  In order to eliminate such problems, a game machine that backs up necessary data when a power failure such as a power failure occurs, restores the backed up data when the power is turned on, and returns to the state when the power failure occurred It has been known. For example, a RAM area checksum is created and saved when the power is turned off, and the RAM area checksum is recreated when power is restored, and the contents of the recreated checksum and the saved checksum contents are compared. Thus, a gaming machine is provided in which the contents of the RAM are inspected, and when the contents of the RAM are identical, the game table is restored to the power-off state (see, for example, Patent Document 1).

JP 2007-125420 A

  However, the game machine described in Patent Document 1 has a problem that the reliability of the check is not sufficient because the contents of the RAM area are inspected only once.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a game machine that improves the reliability of checking the storage contents of a RAM.

  In order to achieve the above object, a game machine according to the present invention is configured as follows.

As an aspect of the gaming machine according to the present invention, when the first condition is satisfied, the numerical value for inspection of the data stored in the first storage area is calculated, and the calculated numerical value for inspection is stored in a predetermined storage unit. Calculating the numerical value for inspection of the data stored in the second storage area that overlaps at least a part of the first storage area when the first condition is satisfied and the first inspection numerical value storage means Second inspection numerical value storage means for storing the inspection numerical value in a predetermined storage unit, and when the second condition is satisfied, the inspection numerical value of the data stored in the first storage area is calculated, and the calculated inspection value First inspection for verifying the content of data stored in the first storage area based on a numerical value and a first inspection numerical value stored in a predetermined storage unit in the first inspection numerical value storage means Numerical verification means and the second storage when the second condition is satisfied An inspection numerical value of the data stored in the area is calculated, and based on the calculated inspection numerical value and the inspection numerical value stored in a predetermined storage unit in the second inspection numerical value storage means, the second Verification for making a predetermined determination based on the verification results of the second inspection numerical verification means for verifying the contents of the data stored in the storage area, and the first inspection numerical verification means and the first inspection numerical verification means And a result judging means.

As a result, the first storage area, which is a large area, can be inspected based on the inspection result, and the second storage area included in the first storage area can be inspected. It can be performed. For example, unnecessary re-inspection can be omitted, and an important area can be re-inspected.

  When the verification result is abnormal in the first inspection numerical verification means, the second inspection numerical verification means is verified, and the verification result determination means is the first inspection numerical verification means. If the verification result is normal, the data stored in the first storage area is restored using the data stored when the first condition is satisfied, and the first inspection numerical verification means If the verification result is abnormal and the verification result is normal in the second inspection numerical verification means, the data stored in the second storage area is stored when the first condition is satisfied. The first storage area excluding the second storage area is initialized, the verification result is abnormal in the first inspection numerical verification means, and the second inspection numerical value is obtained. Validation If the verification result in step is abnormal with respect to the first storage area is characterized by initializing. Thereby, even if the verification result of the first storage area is abnormal, if the verification result of the second storage area is normal, the data stored in the second storage area is It is possible to recover using the stored data.

  Further, the verification result determination means is configured to store the second storage when the verification result is abnormal in the first inspection numerical verification means and the verification result is normal in the second inspection numerical verification means. Also regarding the area, if the verification result is abnormal in the first inspection numerical verification means and the verification result is abnormal in the second inspection numerical verification means, further error notification is performed. It is characterized by. Thereby, a stricter inspection can be performed on the first storage area and the second storage area.

  The verification result determination means is stored in the first storage area when both of the verification results are normal in the first inspection numerical verification means and the second inspection numerical verification means. With respect to the data, the data is restored using the data stored when the first condition is satisfied, and one of the verification results in the first numerical verification unit for inspection and the second numerical verification unit for inspection was abnormal. In this case, the first storage area is initialized. Thereby, a stricter inspection can be performed on the first storage area and the second storage area.

  The overlapping area of the first storage area and the second storage area is a part of the first storage area and a part of the second storage area. As a result, a particularly accurate inspection can be performed with respect to the overlapping portion of the first storage area and the second storage area.

  Further, the verification result judging means is the data stored in the state when the first condition is satisfied for the data in the area where the verification result is normal in the first numerical verification means and the second numerical verification means. It returns by using. As a result, only the area in which correct data is stored is returned to the state in which the first condition is satisfied, so there is no disadvantage to the player.

  The overlapping area between the first storage area and the second storage area stores at least one of information relating to a game or information relating to a player's profit. As a result, important data is stored in the overlap area between the first storage area and the second storage area, and the important data is checked twice. Can be improved.

Upon receiving this signal, the counter circuit 316 latches the value of the counter corresponding to the first special figure starting port 126 at that timing, and stores the latched value in the built-in counter value corresponding to the first special figure starting port 126. Store in the register. Similarly, when the counter circuit 316 receives a signal indicating that the ball has won the second special figure starting port 128, the counter circuit 316 latches the value at the timing of the counter corresponding to the second special figure starting port 128. The latched value is stored in a built-in counter value storage register corresponding to the second special figure starting port 128.

  Further, an information output circuit 334 is connected to the basic circuit 302, and the main control unit 300 is connected to an information input circuit 652 provided in an external hall computer (not shown) or the like via this information output circuit 334. The game information (for example, game state) of the machine 100 is output.

  The main control unit 300 includes an output interface for transmitting a command to the sub-control unit 400 and an output interface for transmitting a command to the payout control unit 550. With this configuration, the sub-control unit 400 In addition, communication with the payout control unit 550 is enabled.

<Sub control unit>
Next, the sub control unit 400 of the pachinko machine 100 will be described.

  The sub-control unit 400 includes a basic circuit 402 that controls the entire sub-control unit 400 mainly based on commands transmitted from the main control unit 300.

The sub-control unit 500 is connected to a chance button detection circuit 380 that detects the pressing of the chance button 146 and outputs a signal.

<Discharge control unit, launch control unit, power supply management unit>
Next, the payout control unit 550, the launch control unit 600, and the power supply management unit 650 of the pachinko machine 100 will be described.

  The payout control unit 550 controls the payout device 552 mainly based on a signal such as a command transmitted from the main control unit 300, and the payout of the winning ball or the rental ball is completed based on a control signal output from the payout sensor 554. It is detected whether or not the card unit 654 is provided separately from the pachinko machine 100 via the interface unit 556.

  The firing control unit 600 determines the amount of operation of the launch handle 148 by the player, which is output from the control signal instructing permission or stop of launch output from the payout control unit 550, or the launch intensity output circuit provided in the operation handle 148. Based on the control signal instructing the corresponding launch intensity, the launch motor 602 that drives the launcher 138 and the launcher 140 is controlled, and the ball feeder 604 that supplies the ball from the storage plate 144 to the launch rail 142 is controlled. .

  The power management unit 650 converts the AC power supplied from the outside to the pachinko machine 100 into a direct current, converts it into a predetermined voltage, and controls the control units such as the main control unit 300 and the sub control unit 400, and the devices such as the dispensing device 552. To supply. Further, the power management unit 650 supplies a power storage circuit (for example, a power supply circuit) for supplying power to a predetermined part (for example, the RAM 308 of the main control unit 300) for a predetermined period (for example, 10 days) even after the external power supply is cut off. Capacitor).

<Data table of main control unit>
Next, a data table stored in the ROM 306 of the main control unit 300 of the pachinko machine 100 will be described with reference to FIG. 2A is an example of a jackpot determination table, FIG. 1B is an example of a high probability state transition determination table, and FIG. 2C is an example of a timer number determination table. is there.

  The jackpot determination table shown in FIG. 6A is the type of information stored in the gaming state storage area provided in the RAM 308 (hereinafter simply referred to as “gaming information”) and the first special figure starting port 126. Lottery data (first special figure starting port lottery data) used when a predetermined ball detection sensor detects that the ball has won, and a predetermined ball indicating that the ball has won the second special figure starting port 128 It is the data table which stored the lottery data (2nd special figure starting port lottery data) used when a detection sensor detects in association with each other. The basic circuit 302 of the main control unit 300 uses these pieces of information to determine whether the special figure variation game is won (big hit) or wrong (miss), that is, “big hit determination”. Note that the “game information” includes information indicating a low probability state in which the special figure variable game is determined to be won with a predetermined low probability, and a high probability state in which the special figure variable game is determined to be a high probability with a higher probability than the low probability. Hereinafter, these are simply referred to as “low probability state” and “high probability state”. Further, the information stored in the game state storage area includes other information, which will be described later.

  The lottery data for the first special figure starting port is used to determine the result of the special figure variable game that starts when a predetermined ball detection sensor detects that a ball has won the first special figure starting port 126. It is lottery data. For example, when the gaming state is in a low probability state, if the acquired special figure winning random number value (the random number value will be described later) is 10001 to 10187, it is determined that the special figure variable game is won. On the other hand, when the acquired special figure winning random number is a numerical value other than 10001 to 10187, it is determined that the special figure variable game is out of play. In the present embodiment, the numerical value range that the special figure winning random number value can take is 0 to 65535 (the numerical value range is 65536), and the numerical value range indicated by the lottery data for the first special figure starting port in the low probability state is 10001. -10187 (the numerical range is 187), the winning probability of the special figure variable game based on the winning of the ball to the first special figure starting port 126 in the low probability state is about 1 / 350.4 (= 187/65536). On the other hand, since the numerical range indicated by the lottery data for the first special figure starting port in the high probability state is 30001 to 13310 (the numerical range is 1310), the first special figure starting port 126 in the high probability state. The winning probability of the special figure variable game based on the winning of the special ball is about 1 / 50.0 (= 1310/65536), and the winning of the special figure variable game based on the winning of the ball to the first special figure starting port 126 is won. The probability is set so that the high probability state is higher than the low probability state.

  The lottery data for the second special figure start port is used to determine the result of the special figure variable game that starts when a predetermined ball detection sensor detects that a ball has won the second special figure start port 128. It is lottery data. For example, when the gaming state is a low probability state and the acquired special figure winning random number value is 20001 to 20187, it is determined that the special figure variable game is won. On the other hand, when the acquired special figure winning random number is a numerical value other than 20001 to 20187, it is determined that the special figure variable game is out of play. In the present embodiment, the numerical value range that the special figure winning random number value can take is 0 to 65535 (the numerical value range is 65536), and the numerical value range indicated by the lottery data for the second special figure starting port in the low probability state is 20001. Since it is ˜20187 (the size of the numerical range is 187), the winning probability of the special figure variable game based on the winning of the ball to the second special figure starting port 128 in the low probability state is about 1 / 350.4 (= 187/65536). On the other hand, since the numerical range indicated by the lottery data for the second special figure starting port in the high probability state is 40001 to 41310 (the numerical range is 1310), the second special figure starting port 128 in the high probability state. The winning probability of the special figure variable game based on the winning of the special ball is about 1 / 50.0 (= 1310/65536), and the winning of the special figure variable game based on the winning of the ball to the second special figure starting port 128 is won. The probability is set so that the high probability state is higher than the low probability state.

  The high-probability state transition determination table shown in FIG. 6B is a data table storing lottery data used when it is determined that the jackpot is determined as a result of the jackpot determination.

  The basic circuit 302 of the main control unit 300 uses this high probability state transition determination table to determine whether to start a jackpot game or a special jackpot game after the end of the special figure variable game, that is, a probability change transition determination. I do. For example, if the acquired special figure random number value (the random number value will be described later) is a numerical value of 64 to 127, in the storage area of the probability change (probability fluctuation) flag provided in the RAM 308, after the special figure fluctuation game ends. Information indicating that the special jackpot game is started is set (here, setting the special jackpot game start information in the storage area for the probability change flag is referred to as turning on the probability change flag). On the other hand, when the acquired special figure random number value is other than a numerical value of 64 to 127, information indicating that the jackpot game is started is set in the above-described probability variation flag storage area (where the probability variation flag is stored). Setting the jackpot game start information in the area is referred to as setting the probability variation flag off). In the present embodiment, the numerical value range that the special figure random number value can take is 0 to 127 (the numerical value range is 128), and the lottery data migration determination random number range is 64 to 127 (the numerical value range is 64). Therefore, when the result of the jackpot determination is winning, the probability of winning the result of the probability change transition determination, that is, the probability of starting the special jackpot is 1/2 (= 64/128).

  The timer number determination table shown in FIG. 6C is used for a lottery for determining a timer number indicating a variation time from the start of the variation display of the special diagram by the special diagram display device 114 to the stop display. It is a data table which memorize | stored lottery data. The basic circuit 302 of the main control unit 300 determines a timer number based on this information, the above jackpot determination result (a value of a jackpot flag described later), and a timer random number value described later. In the present embodiment, the range of numerical values that can be taken by the special figure timer random number value (the random number value will be described later) is 0 to 65535 (the size of the numerical range is 65536), and the above jackpot determination result is unfair Since the range of the timer random number of timer 1 is 0 to 60235 (the size of the numerical range is 60236), the probability of selecting timer 1 (fluctuation time 5 seconds, no reach) as the timer number is 60236/65536. As a timer number, the probability of selecting timer 2 (variation time 10 seconds, normal reach) is 4250/65536, the probability of selecting timer 3 (variation time 20 seconds, long reach) is 800/65536, timer 3 (variation time) The probability of selecting 40 seconds, multiline reach) is 250/65536. On the other hand, if the jackpot determination result is winning, the timer random number range of timer 2 is 0 to 15535 (the numerical range is 15536), so timer 2 (variation time 10 seconds, normal reach) is selected as the timer number The probability of doing is 15535/65536. As a timer number, the probability of selecting timer 3 (variation time 20 seconds, long reach, normal reach (revariation)) is 9000/65536, and the probability of selecting timer 4 (variation time 40 seconds, multiline reach) is 38000. The probability of selecting / 65536, timer 5 (variation time 50 seconds, full rotation reach) is 3000/65536.

<Data table of sub-control unit>
Next, a data table stored in the ROM 406 of the sub-control unit 400 of the pachinko machine 100 will be described with reference to FIGS.

  FIG. 7A shows an example of a variable number selection table used when the result of the jackpot determination is unsuccessful (a jackpot flag to be described later is off), and FIG. 7B shows the jackpot described above. It shows an example of a variable number selection table used when the result of the determination is winning (a jackpot flag to be described later is on).

  The variation number selection tables shown in FIGS. 4A and 4B are data tables for determining the effect display mode in the decorative symbol display device 110, and the timer number and the result of the above-described probability variation transition determination (the probability variation described later). Flag value) and a change number based on a change determination random number value to be described later. In the column corresponding to the item “variation mode” of the variation number selection table, the variation mode corresponding to the variation number is described for reference. For example, when the variation 11 of the variation number is selected, When the display control of the decorative symbol display device 110 is performed in a variation mode “long reach” described later and the variation number variation 19 is selected, the display control of the decoration symbol display device 110 in a variation mode “full rotation reach” described later. Shows you to do.

  For example, when the result of the jackpot determination is incorrect, the timer number is timer 1, and the probability variation flag is on (or off), the variation number selection table shown in FIG. 7A when the jackpot flag is off. Refer to In this case, since the numerical range of the random number for variation determination corresponding to timer number = timer 1 is 0 to 127 (the numerical range has a size of 128), the probability is 100% (= 128/128) as the variation number. That is, the variation 1 is selected regardless of the obtained variation determining random value, and information indicating that the selection result is variation 1 is stored in the variation number storage area provided in the RAM 408. Also, when the jackpot determination result is won and the timer number is timer 2 and the probability variation flag is off, the variation number selection table shown in FIG. 7B when the jackpot flag is on is referred to. In this case, the numerical range of the random number for variation determination corresponding to timer number = timer 2 and probability variation flag = off is 0 to 47 (the numerical range is 48) and 48 to 127 (the numerical range is 80). Therefore, as a variation number, variation 6 is selected with a probability of 48/128, and variation 7 is selected with a probability of 80/128.

  8 to 9 show combinations of temporary stop symbols to be temporarily stopped by the decorative symbol display device 110 based on the variable number determined using FIG. 7, the value of a random number for determining symbols to be described later, and the stop symbols to be stopped and displayed. FIG. 8A is a diagram showing an example of a symbol determination table for determining a combination. FIG. 8A is used when the variation number is variation 1, and determines the type of decoration symbol combination to be temporarily stopped and stopped. (B) shows an example of a symbol determination table corresponding to fluctuations 2 to 5, and (c) shows a symbol corresponding to fluctuations 6, 10, 13, 14, and 18. FIG. 4D shows an example of the determination table, and FIG. 4D shows an example of the symbol determination table corresponding to the variation 7. 9A shows an example of the symbol determination table corresponding to the variation 9, FIG. 9B shows an example of the symbol determination table corresponding to the variations 11, 15, 16, and 19, and FIG. An example of the symbol determination table corresponding to the variations 8, 17, and 20 is shown in FIG. 9D, and an example of the symbol determination table corresponding to the variation 12 is shown. The temporary stop symbol combination indicates a temporary stop symbol combination that temporarily stops before the symbol becomes the stop symbol combination, and the stop symbol combination indicates the stop symbol combination that is finally stopped. Is shown.

  Moreover, the symbol determination table corresponding to the fluctuations 1 to 5 shown in FIGS. 8A and 8B is a table to be selected when the jackpot determination is unsuccessful (in the case of losing), and FIG. ) And (d), the symbol determination table corresponding to the fluctuations 6, 10, 14, 18, and 7 is a table that is selected when the jackpot determination is a win and the probability change transition determination is an incorrect selection (in the case of a jackpot). 9 (a) to 9 (d), the symbol determination table corresponding to the fluctuations 9, 11, 15, 16, 19, 8, 17, 20, and 12 has won the jackpot determination and the winning change transition determination has also been won. It is a table to select in case (special jackpot). Here, the tables shown in FIGS. 9A to 9D are configured to be selected only in the case of a special jackpot. When a combination of stop symbols is selected using this table, a symbol display is displayed. The area 110a to 110c includes a case where the symbol combination corresponding to the jackpot is stopped and displayed instead of the symbol combination corresponding to the special jackpot. Of course, a special jackpot game is started after the stop display, and a high probability state is set after the jackpot operation is finished.

  For example, when the variation number is variation 6, the sub control unit 400 refers to the symbol determination table shown in FIG. In this case, the numerical value range of the symbol determining random value corresponding to the variation 6 (the random value will be described later) is 0 to 25 (the numerical value range is 26), and 26 to 51 (the numerical value range is 26). ) 52 to 77 (the numerical range size is 26), 78 to 102 (the numerical range size is 25), and 103 to 127 (the numerical range size is 25). As a combination, “decoration 2—decoration 2—decoration 2”, “decoration 4—decoration 4—decoration 4”, “decoration 6—decoration 6—decoration 6”, “decoration 8—decoration” with a probability of about 1/5 each. Either “8-decoration 8” or “decoration 10-decoration 10-decoration 10” is selected.

<Main control unit main processing>
Next, main control unit main processing executed by the CPU 304 of the main control unit 300 will be described with reference to FIG. This figure is a flowchart showing the flow of main processing of the main control unit.

  The main controller 300 is provided with a start signal output circuit (reset signal output circuit) that outputs a start signal (reset signal) when the power is turned on. The CPU 304 of the basic circuit 302 to which this activation signal has been input starts reset by a reset interrupt and executes processing in accordance with a control program stored in advance in the ROM 306.

  In step S101, initial setting 1 is performed. In the initial setting 1, the stack initial value is set in the stack pointer (SP) of the CPU 304, the interrupt mask is set, the initial setting of the I / O port 310, the initial setting of various variables stored in the RAM 308, and the initial value in the WDT. Set up. In the present embodiment, a numerical value corresponding to 32.8 ms is set as the initial value in WDT.

  In step S102, WDT is reset and time measurement by WDT is restarted.

  In step S103, whether or not the low voltage signal is on, that is, the voltage value of the power source supplied from the power management unit 650 to the main control unit 300 by the voltage monitoring circuit 336 provided in the main control unit 300 is determined. It is monitored whether or not a low voltage signal indicating that the voltage has decreased is output when it is less than a predetermined value (9v in the present embodiment). If the low voltage signal is on (when the CPU 304 detects that the power supply has been shut off), the process returns to step S102. If the low voltage signal is off (if the CPU 304 has not detected the power supply being cut off), the process proceeds to step S102. The process proceeds to S104.

  In step S104, initial setting 2 is performed. In this initial setting 2, a process for setting a numerical value for determining a cycle for executing a main control unit timer interrupt process, which will be described later, in the counter timer 312 and a predetermined port of the I / O 310 (for example, a test output port, a sub-port) Processing for outputting a clear signal from the output port to the control unit 400, setting for permitting writing to the RAM 308, and the like are performed.

  In step S105, a RAM area inspection process is performed. In this RAM area inspection process, the RAM area is inspected to determine whether or not to return to the state before the power is shut off (before the power interruption). Specifically, a checksum (a check for checking whether there is an error in data) is performed by adding all 1-byte data stored in a predetermined area (for example, all areas) of the RAM 308 to a 1-byte register. Numerical value) is calculated, and whether or not the result of the calculated checksum matches the checksum calculated and stored at the time of power interruption is determined to return to the state before the power interruption. Determine whether or not.

  When the state before power interruption is not restored (when the basic circuit 302 of the main control unit 300 is set to the initial state), initialization processing is performed. In the initialization process, interrupt prohibition setting, stack initial value setting to the stack pointer, initialization of all storage areas of the RAM 308, and the like are performed. Further, when returning to the state before the power interruption, a power recovery process is performed. In the power recovery process, the stack pointer stored in the stack pointer save area provided in the RAM 308 at the time of power failure is read and reset to the stack pointer. In addition, the value of each register stored in the register save area provided in the RAM 308 at the time of power interruption is read out, reset to each register, and then the interrupt permission is set. Thereafter, as a result of the CPU 304 executing the control program based on the reset stack pointer and registers, the pachinko machine 100 returns to the state when the power is turned off. That is, the processing is restarted from the instruction next to the instruction (predetermined in steps S106 and S107) performed immediately before branching to the timer interrupt processing (described later) immediately before the power interruption. The RAM area inspection process in step S105 will be described in detail later.

    In step S106, the basic random number initial value update process is performed after setting the interrupt inhibition. In this basic random number initial value update process, two initial value generation random number counters for generating the initial values of the normal figure winning random number counter and the special figure random value counter, the normal figure timer random number value, and the special figure timer random number counter, respectively. Two random number counters for generating numerical values are updated. For example, if the range of values that can be taken as normal timer random numbers is 0 to 20, a value is acquired from a random number counter storage area for generating a normal timer random value provided in the RAM 308, and 1 is added to the acquired value. Then, it is stored in the original random number counter storage area. At this time, if the result of adding 1 to the acquired value is 21, 0 is stored in the original random number counter storage area. Other initial value generation random number counters and random number counters are similarly updated. Further, after this basic random number initial value update process is completed, an interrupt permission is set, and the process proceeds to step S107.

  In step S107, effect random number update processing is performed. In this effect random number update process, a random number counter for generating an effect random number used by the main control unit 300 is updated.

  The main control unit 300 repeatedly executes the processes of steps S106 and S107 except during the timer interrupt process starting every predetermined period.

<Main controller timer interrupt processing>
Next, main control unit timer interrupt processing executed by the CPU 304 of the main control unit 300 will be described with reference to FIG. This figure is a flowchart showing the flow of main controller timer interrupt processing.

  The main control unit 300 includes a counter timer 312 that generates a timer interrupt signal at a predetermined cycle (in this embodiment, about once every 2 ms). The timer interrupt signal is used as a trigger to perform main control unit timer interrupt processing. Start with a period of

  In step S201, timer interrupt start processing is performed. In this timer interrupt start process, a process of temporarily saving the value of each register of the CPU 304 to the stack area is performed.

  In step S202, the WDT count value exceeds the initial setting value (32.8 ms in the present embodiment) and does not generate a WDT interrupt (so as not to detect a processing abnormality). In the embodiment, the restart is performed once every about 2 ms, which is the period of the main control unit timer interrupt.

  In step S203, input port state update processing is performed. In this input port state update process, detection signals of various sensors 318 including the above-described glass frame opening sensor, front frame opening sensor, lower pan full sensor, and a plurality of ball detection sensors are input via the input port of the I / O 310. Then, the presence or absence of a detection signal is monitored and stored in a signal state storage area provided for each of the various sensors 318 in the RAM 308. In this embodiment, information on the presence or absence of the detection signal of each sphere detection sensor detected in the timer interruption process of the last time (about 4 ms before) is stored in the RAM 308 for each previous sphere detection sensor. This information is read from the area, and this information is stored in the RAM 308 in the detection signal storage area provided in advance for each sphere detection sensor, and the detection of each sphere detection sensor detected by the previous timer interruption process (about 2 ms before). Information on the presence or absence of a signal is read from the current detection signal storage area provided in the RAM 308 for each sphere detection sensor, and this information is stored in the previous detection signal storage area. Further, the detection signal of each sphere detection sensor detected this time is stored in the above-described current detection signal storage area.

  In step S203, the information on the presence / absence of the detection signal of each sphere detection sensor stored in each storage area of the detection signal recording area, the previous detection signal recording area, and the current detection signal recording area is compared. It is determined whether or not the information on the presence / absence of detection signals for the past three times in the sphere detection sensor of the two sphere detection sensors matches. The information on the presence / absence of detection signals for the past three times in each sphere detection sensor is predetermined winning determination pattern information (in this embodiment, no previous detection signal, previous detection signal, current detection signal) In the case of a match to the winning opening (the general winning opening 122, the variable winning opening 130) or the starting opening (the first special figure starting opening 126, the second special drawing starting opening 128), It is determined that the starting port 124 has passed. For example, if the information on the presence / absence of detection signals for the past three matches with the above-described winning determination pattern information in the ball detection sensor that detects the winning at the general winning opening 122, it is assumed that the player has entered the general winning opening 122. After determining and performing the process associated with the subsequent entry to the general winning opening 122, if the information on the presence or absence of the detection signals for the past three times does not match the above-described winning determination pattern information, The process branches to the subsequent process without performing the process associated with entering the mouth 122.

  In step S204 and step S205, basic random number initial value update processing and basic random number update processing are performed. In these basic random number initial value update processing and basic random number update processing, the value of the initial value generation random number counter performed in step S108 is updated, and then the normal winning random number value and special value used in the main control unit 300 are updated. The two random number counters for generating the figure random number values are updated. For example, if the range of values that can be taken as a random number value for a normal winning number is 0 to 100, a value is acquired from a random number counter storage area for generating a normal winning random number value provided in the RAM 308 and 1 is added to the acquired value. Then, it is stored in the original random number counter storage area. At this time, if the result of adding 1 to the acquired value is 101, 0 is stored in the original random number counter storage area. If it is determined that the random number counter has made one round as a result of adding 1 to the acquired value, the value of the initial value generating random number counter corresponding to each random number counter is acquired and stored in the storage area of the random number counter. set. For example, a value is acquired from a random number counter for generating a regular winning random number that fluctuates in a numerical range of 0 to 100, and a result obtained by adding 1 to the acquired value is stored in a predetermined initial value storage area provided in the RAM 308. If the value is equal to the previously set initial value (for example, 7), the value is acquired as an initial value from the initial value generation random number counter corresponding to the random number counter for generating the random number for winning the normal number, The initial value set this time is stored in the above-described initial value storage area in order to determine that the random number counter for generating the winning random number value has made one round next time, in addition to setting it in the random number counter for generating the winning random value Keep it. In addition to the above-described initial value storage area for determining that the random number counter for generating the regular-winning random number next makes one round, it is determined that the random number counter for generating the special figure random number has made one round. An initial value storage area is provided in the RAM 308.

  In step S206, effect random number update processing is performed. In this effect random number update process, a random number counter for generating an effect random number used by the main control unit 300 is updated.

  In step S207, timer update processing is performed. In this timer update process, a normal symbol display symbol update timer for timing the time for the symbol to be changed / stopped on the normal symbol display device 112, and a time for the symbol to be changed / stopped to be displayed on the special symbol display device 114. Various timers including a special figure display symbol update timer, a timer for measuring a predetermined winning effect time, a predetermined opening time, a predetermined closing time, a predetermined end effect period, and the like are updated.

  In step S208, winning prize counter updating processing is performed. In this winning opening counter updating process, when there is a winning (winning) in the winning opening (the general winning opening 122, the first and second special figure starting openings 126, 128, and the variable winning opening 130), The value of the winning ball number storage area provided for each winning opening is read, and 1 is added to set the original winning ball number storage area.

  In step S209, a winning acceptance process is performed. In this winning acceptance process, if there is a prize at the first and second special figure starting ports 126 and 128 and the number of special figure variable games held is less than four, it corresponds to the winning starting port. The value is acquired from the counter value storage register of the counter circuit 316 to be a special figure winning random number value. In addition, a value is acquired as a special figure random value from the random number counter for generating the special figure random value described above, and stored in a random value storage area provided in the RAM 308 together with the special figure winning random number value. In addition, when it is detected that the ball has passed through the general figure starting port 124, and the number of the general figure variable games held is less than two, the random number counter for generating the normal figure winning random number value at that timing Is obtained as a random number value for normal winning, and is stored in a random number value storage area provided in the RAM 308 different from that for the above special figure. In this winning acceptance process, if a predetermined ball detection sensor detects a winning (winning) at the first and second special figure starting ports 126, 128, the ordinary starting port 124, or a variable winning port, In the transmission information to be transmitted to the control unit 400, winning acceptance information indicating presence / absence of winning (winning) of the first and second special figure starting ports 126 and 128, the universal drawing starting port 124, and the variable winning port is set. .

  In step S210, a payout request number transmission process is performed. The output schedule information and the payout request information output to the payout control unit 550 are composed of 1 byte, strobe information in bit 7 (indicating that data is set when on), and power supply in bit 6 Input information (when ON, indicates that this is the first command transmission after power-on), bits 4-5 indicate the current processing type (0-3), and bits 0-3 indicate the number of payout requests after processing I am doing so.

  In step S211, a normal state update process is performed. This normal state update process performs one of a plurality of processes corresponding to the normal state. For example, in a normal diagram state update process during a normal map change (the value of the general-purpose general-purpose timer is 1 or more), lighting / extinguishing drive control for repeatedly turning on and off the 7-segment LED constituting the universal map display device 112 is performed.

  Further, in the general chart state update process at the timing when the normal map change display time has elapsed (the timing when the value of the general map display symbol update timer has changed from 1 to 0), when the hit flag is on, FIG. When the 7-segment LED constituting the universal display device 112 is controlled to be turned on / off so as to be in the form shown in FIG. 1 and the hit flag is off, the normal figure shown in FIG. In the RAM 308, in order to maintain the display for a predetermined stop display period (for example, 500 msec), the 7-segment LED constituting the ordinary display device 112 is controlled to be turned on / off so as to be in the second mode. In addition, information indicating the stop period is set in the storage area of the normal stop time management timer. With this setting, the usual figure is stopped and the result of the usual figure variable game is notified to the player.

  Further, in the normal state update process that starts at the timing when the predetermined stop display period ends (when the value of the normal stop time management timer value changes from 1 to 0), if the hit flag is on, the predetermined state is displayed. During the opening period (for example, 2 seconds), a signal for holding the blade member in an open state is output to the solenoid 330 for opening and closing the blade member of the second special figure starting port 128, and the blade opening time management provided in the RAM 308 is controlled. Information indicating the release period is set in the storage area of the timer.

  In the usual state update process that starts at the timing when the predetermined opening period ends (the timing when the value of the blade opening time management timer is changed from 1 to 0), the blade member has a predetermined closing period (for example, 500 milliseconds). A signal for holding the blade member in a closed state is output to the opening / closing drive solenoid 330, and information indicating the closing period is set in the storage area of the blade closing time management timer provided in the RAM 308.

  In the normal state update process that starts at the timing when a predetermined closing period has elapsed (the timing when the value of the blade closing time management timer changes from 1 to 0), the normal state is set to inactive. In the normal state update process when the normal state is inactive, the process proceeds to the next step S212 without doing anything.

  In step S212, a general drawing related lottery process is performed. In this general map-related lottery process, the open / close control of the general map variable game and the second special map start port 128 is not performed (the state of the general map is not in operation), and the pending general map variable game is not held. When the number is 1 or more, it is decided whether to win or not to win the result of the variable figure game by random lottery based on the random number value stored in the random number value storage area. When the winning judgment is made and the winning is made, the winning flag provided in the RAM 308 is set to ON. If unsuccessful, turn off the winning flag. Regardless of the result of the hit determination, next, the value of the random number counter for generating the normal figure timer random value is acquired as the normal figure timer random number value, and a plurality of fluctuation times are obtained based on the acquired general figure timer random number value. One time for displaying the variable map on the general map display device 112 is selected from among them, and this variable display time is stored in the general map variable time storage area provided in the RAM 308 as the normal map variable display time. In addition, the number of pending general figure variable games is stored in the usual figure pending number storage area provided in the RAM 308, and from the number of pending custom figure variable games each time a hit determination is made. The value obtained by subtracting 1 is re-stored in the usual figure number-of-holds storage area. Also, the random number value used for the hit determination is deleted.

  In step S213, special figure state update processing is performed. This special figure state update process performs one of a plurality of processes corresponding to the special figure state. For example, in the special figure state update process during the special figure fluctuation (the special figure general-purpose timer value is 1 or more), the lighting / extinguishing drive control for repeatedly turning on and off the 7-segment LED constituting the special figure display device 112 is performed.

  Also, in the special figure state update process that starts at the timing when the special figure change display time has elapsed (when the special figure display symbol update timer value changes from 1 to 0), the jackpot flag is on and the probability change flag is off When the special figure display device 114 has the special figure 1 shown in FIG. 4A and the jackpot flag is on and the probability variation flag is on, the special figure display device 114 has the special figure 2 shown in FIG. When the flag is OFF, the 7 segment LED constituting the special figure display device 112 is controlled to be turned on / off so that the special figure display device 112 shown in FIG. In order to maintain the display period (for example, 500 milliseconds), information indicating the stop period is set in the storage area of the special figure stop time management timer provided in the RAM 308. With this setting, the special figure is stopped and displayed, and the result of the special figure variable game is notified to the player. Further, 02H is additionally stored as transmission information (general information) in the transmission information storage area described above in order to execute the general command rotation stop setting transmission process in the command setting transmission process (step S215).

  Further, in the special figure state update process that starts at the timing when the predetermined stop display period ends (the timing at which the special figure stop time management timer value changes from 1 to 0), if the jackpot flag is on, a predetermined value is displayed. A special figure waiting time management timer provided in the RAM 308 for waiting for a period during which an image for notifying the player that a big hit by the decorative symbol display device 110 is started, that is, a bonus winning period (for example, 3 seconds) is displayed. Information indicating the winning effect period is set in the storage area. Further, 04H is additionally stored as transmission information (general information) in the transmission information storage area described above in order to execute the general command winning effect setting transmission process in the command setting transmission process (step S215).

  Also, in the special figure state update process that starts at the timing when the predetermined winning effect period ends (the timing when the special figure standby time management timer value changes from 1 to 0), a predetermined release period (for example, 29 seconds or A signal for holding the door member in an open state is output to the solenoid 330 for opening and closing the door member of the variable prize opening 130 (until a winning of a game ball of a predetermined number (for example, 10 balls) is detected in the variable prize opening 130). At the same time, information indicating the opening period is set in the storage area of the door opening time management timer provided in the RAM 308. Further, 10H is additionally stored as transmission information (general information) in the above-described transmission information storage area in order to execute the general command big prize opening release setting transmission process in the command setting transmission process (step S215).

  In the special figure state update process that starts at the timing when the predetermined opening period ends (the timing when the door opening time management timer value changes from 1 to 0), the predetermined closing period (for example, 1.5 seconds) is variable. A signal for holding the door member in the closed state is output to the solenoid 330 for opening and closing the door member of the winning opening 130, and information indicating the closing period is set in the storage area of the door closing time management timer provided in the RAM 308. To do. Further, 20H is additionally stored as transmission information (general information) in the above-described transmission information storage area in order to execute the general command big prize opening closing setting transmission process in the command setting transmission process (step S215).

  Further, in the special figure state update processing which is repeated at predetermined timing (for example, 15 rounds) and the opening / closing control of the door member is repeated a predetermined number of times (for example, 15 rounds), Information indicating the effect standby period is set in the storage area of the effect standby time management timer provided in the RAM 308 in order to set to wait for a period during which an image for informing the player that the jackpot is to be ended is displayed. Further, 08H is additionally stored as transmission information (general information) in the above-described transmission information storage area in order to execute the general command end effect setting transmission process in the command setting transmission process (step S215).

  Further, in the special figure state update process which starts at the timing when the predetermined end production period ends (the timing when the production standby time management timer value changes from 1 to 0), the special figure state is set to inactive. . In the special figure state update process when the special figure is in a non-operating state, nothing is done and the process proceeds to the next step S214.

  In step S214, special drawing related lottery processing is performed. In this special drawing-related lottery process, the opening / closing control of the special drawing variable game and the variable winning opening 130 is not performed (the state of the special drawing is inactive), and the number of the special drawing variable games held is 1 In the case of the above, among the various lotteries using the jackpot determination table in FIG. 6A, the high probability state transition determination table in FIG. 6B, the timer number determination table in FIG. First, a jackpot determination is performed. Specifically, whether or not the special figure winning random number value stored in the random value storage area in step S203 is within the numerical range of the first special figure starting port lottery data in the jackpot determination table shown in FIG. If the special figure winning random number value is within the numerical range of the lottery data for the first special figure starting port, it is determined that the special figure variable game is won and the jackpot flag stored in the RAM 308 is stored in the big hit flag storage area. (In this case, setting the jackpot information in the RAM 308 is setting the jackpot flag to ON). On the other hand, when the special figure winning random number value is outside the numerical range of the lottery data for the first special figure starting port, it is determined that the special figure variable game is out of the game, and the jackpot flag storage area provided in the RAM 308 is out of the storage area. (In this case, setting outlier information in the RAM 308 is setting the jackpot flag off). Note that the number of special figure variable games held is stored in the special figure hold number storage area provided in the RAM 308. Each time a hit determination is made, the number of special figure variable games held is determined. The value obtained by subtracting 1 is stored again in this special figure reservation number storage area. In addition, the random number value used for the hit determination is deleted.

  As a specific example, when the gaming state is a low probability state, and the special figure winning random number value acquired based on the detection of the ball winning to the first special figure starting port 126 is 10100, the jackpot flag is set to ON, When the special figure winning random number is 10200, the jackpot flag is set to OFF. In addition, when the special figure winning random number acquired based on the detection of the ball winning at the second special figure starting port 128 is 20100, the jackpot flag is set to ON, and when the special figure winning random number is 20200, the jackpot flag is set. Set to off.

  If the jackpot flag is set to ON, then the probability variation transition determination is performed. Specifically, it is determined whether or not the special figure random value stored in the random value storage area in step S209 is within the numerical range of the transition determination random number shown in FIG. Is set in the storage area of the probability variation (probability variation) flag provided in the RAM 308, information indicating that the special jackpot game is started. (Here, setting the special jackpot game start information in the RAM 308 is referred to as turning on the probability variation flag). On the other hand, if the special figure random number value is outside the numerical range of the lottery data, information indicating that the jackpot game is started is set in the storage area of the probability variation flag (here, the information on the start of the jackpot game is set). Setting in the RAM 308 is referred to as setting the probability variation flag off). For example, when the acquired special figure random number value is 20, the probability variation flag is set to OFF. On the other hand, when the acquired special figure random value is 80, the probability variation flag is set to ON.

  Regardless of the result of the jackpot determination, the process for determining the timer number is performed next. Specifically, the value of the random counter for generating the special figure timer random value described above is acquired as the special figure timer random value. A timer number corresponding to the numerical value range of the timer random number shown in FIG. 6C including the value of the jackpot flag and the acquired special figure timer random number value is selected and stored in a predetermined timer number storage area provided in the RAM 308. Further, the fluctuation time corresponding to the timer number is stored as the special figure fluctuation display time in the special figure display symbol update timer, and the general command rotation start setting transmission process is executed in the command setting transmission process (step S215). Therefore, the process is terminated after additionally storing as transmission information (general information) in the transmission information storage area described above.

  For example, when the jackpot flag is off and the acquired special figure timer random number value is 50000, the special figure timer random number value is in the range of 0 to 60235, and therefore 1 corresponding to those conditions of the timer number determination table. The timer 1 indicating the timer number stored in the line and 5 indicating the variation time are selected and stored in the respective storage areas provided in the RAM 308. On the other hand, when the jackpot flag is on and the acquired special figure timer random number value is 64000, the special figure timer random number value is not in the range of 0 to 15535, so the timer 2 is not selected and is not 15536 to 24535. Timer 3 is not selected, and timer 4 is not selected because it is not 24536 to 62535. However, since it is within the range of 62536 to 65535, it is stored in the eighth line corresponding to those conditions in the timer number determination table. The timer 5 indicating the timer number and the variable time 50 are selected and stored in the respective storage areas provided in the RAM 308. In consideration of 2 ms which is the start cycle of the interrupt processing, a value obtained by multiplying the selected variation time value by 500 (1000 ms / 2 ms) is set in the variation time storage area. For example, when the variation time is 5 seconds, a value of 2500 is set as an initial value in the variation time storage area, and the value of the variation time storage area is set to 1 each time the timer update process in step S207 is executed. By subtracting, the passage of time can be measured by the number of execution times of interrupt processing. Further, when the value of the variable time storage area is subtracted every time (for example, five times) the timer interrupt process is executed (for example, 2 ms cycle), if the variable time is 10 seconds, 10 seconds is required. Since it is 10000 ms, dividing by the period (2 ms × 5) sets 1000 to the variable time storage area.

  In step S215, command setting transmission processing is performed. The output schedule information transmitted to the sub-control unit 400 is composed of 16 bits, bit 15 is strobe information (indicating that data is set when ON), bits 11 to 14 are command types ( 00H is the basic command, 01H is the symbol variation start command, 04H is the symbol variation stop command, 05H is the winning effect start command, 06H is the end effect start command, and 07H is the number of jackpot rounds Designated command, information that can specify the type of command such as a power recovery command in the case of 0EH and a RAM clear command in the case of 0FH), and bits 0 to 10 are command data (predetermined information corresponding to the command type) It is composed.

  Specifically, the strobe information is turned on and off in the command transmission process described above. If the command type is a symbol variation start command, the command data includes information indicating the value of the jackpot flag, the probability variation flag, the timer number selected in the special symbol related lottery process, etc. If it is a case, it includes the value of the jackpot flag, the probability variation flag, etc. If it is a winning effect command and an end effect start command, it includes the value of the probability variation flag, etc. If it is a jackpot round number designation command The value of the probability variation flag, the number of jackpot rounds, etc. are included. When the command type indicates a basic command, device information in the command data, presence / absence of winning at the first special figure starting port 126, presence / absence of winning at the second special figure starting port 128, winning of the variable winning port 130 Includes presence or absence.

  In the general command rotation start setting transmission process described above, the command type is 01H, the jackpot flag value stored in the RAM 308 as the command data, the probability variation flag value, the timer number selected in the special drawing related lottery process, the pending Information indicating the number of special figure variable games being set is set. In the general command rotation stop setting transmission process described above, 04H is set as the command type, and information indicating the value of the jackpot flag, the value of the probability variation flag, etc. stored in the RAM 308 is set as the command data. In the above-described general command winning effect setting transmission process, the effect control information to be output to the decorative symbol display device 110, various lamps 420, and the speaker 416 during the winning effect period stored in the RAM 308 as the command type and 05H as command type Information indicating the value of the flag, the number of special figure variable games that are held, and the like are set. In the general command end effect setting transmission process described above, the effect control information to be output to the decorative symbol display device 110, various lamps 420, and the speaker 416 during the effect standby period stored in the RAM 308 as the command type is stored in the command type 06H. Information indicating the value of the flag, the number of special figure variable games that are held, and the like are set. In the general command big prize opening release transmission process described above, the information indicating the command type is 07H, the number of big hits stored in the RAM 308 as the command data, the value of the probability variation flag, the number of the special figure variable games held, etc. Set. In the above-described general command big prize closing setting transmission process, the information indicating the command type is 08H, the number of jackpot rounds stored in the RAM 308 as the command data, the value of the probability variation flag, the number of the special figure variable games held, etc. Set. In the sub-control unit 400, it is possible to determine the effect control according to the change of the game control in the main control unit 300 by the command type included in the received output schedule information, and the command data included in the output schedule information Based on this information, the contents of the effect control can be determined.

  In step S216, an external output signal setting process is performed. In this external output signal setting process, the game information stored in the RAM 308 is output to the information input circuit 652 that is separate from the pachinko machine 100 via the information output circuit 334.

  In step S217, device monitoring processing is performed. In this device monitoring process, the signal states of various sensors stored in the signal state storage area in step 203 are read to monitor whether there is a glass frame opening error, a front frame opening error, or a lower pan full error. When a glass frame open error, front frame open error, or lower pan full error is detected, the transmission information to be transmitted to the sub-control unit 400 includes a glass frame open error, a front frame open error, a lower pan Set device information that indicates whether a full error has occurred. In addition, the solenoids 330 are driven to control the opening and closing of the second special figure starting port 128 and the variable prize opening 130, and the general diagram display device 112 and the special figure display device 114 are provided via the display circuits 322, 324, and 328. The display data to be output to the various status display units 326 and the like is set in the output port of the I / O 310. Further, the output schedule information set in the payout request number transmission process (step S210) is set in the output port of the I / O 310.

  In step S218, it is monitored whether or not the low voltage signal is on. Then, when the low voltage signal is on (when power supply shutoff is detected), the process proceeds to step S219, and when the low voltage signal is off (power supply shutoff is not detected), the process proceeds to step S220.

  In step S219, timer interrupt end processing is performed. In this timer interrupt end process, the value of each register temporarily saved in step S201 is set in each original register, or interrupt permission is set.

  In step S220, the voltage monitoring circuit that monitors the voltage value of the power supplied from the power management unit 650 to the main control unit 300 outputs a voltage drop signal indicating that the voltage has dropped when it is equal to or lower than a predetermined value. Whether or not a power-off is detected. If a power-off is detected, a specific variable or stack pointer for returning to the power-off state at the time of power recovery is displayed. The return data is saved in a predetermined area of the RAM 308, and power interruption processing such as initialization of the input / output port is performed. Details of the power interruption process in step S220 will be described later.

  In step S401, the contents of a command storage area to be described later are confirmed, and it is determined whether or not an unprocessed command remains. If an unprocessed command remains in the command storage area, the process proceeds to step S402. If an unprocessed command does not remain in the command storage area, the process ends and returns to the sub-control unit main process. .

  FIG. 12C is a flowchart showing the flow of the variation pattern selection process, and FIG. 12D is a flowchart showing the flow of the symbol stop process. In step S402, based on the type of unprocessed command to be processed next among the unprocessed commands stored in the command storage area, the variation pattern selection process shown in FIG. This is executed based on the change start command) and the symbol stop process shown in FIG. There are other processes based on unprocessed commands. For example, a round start command that is output from the main control unit 300 every time the opening control of the variable winning opening 130 is started during the jackpot and includes information indicating the number of opening of the variable winning opening 130 after the jackpot start is an unprocessed command. For example, a round start process is performed. Other processing is omitted here.

  In step S501 of the variation pattern selection process, the value of the jackpot flag, the probability variation flag, and the timer number included in the unprocessed command are extracted and stored in the respective storage areas of the RAM 408. Further, referring to the variation number selection table in FIG. 7A or 7B and the symbol determination table shown in FIGS. 8 to 9, the effect data (in this embodiment, the combination of variation number, temporary stop symbol / stop symbol) And the like are stored in the storage area provided in the RAM 408, and the process is terminated.

  In step S601 of the symbol stop process, the three decorative symbols constituting the combination of the stopped symbols stored in the symbol storage area are displayed in the three displays of the left, middle and right symbol display areas 110a to 110c of the decorative symbol display device 110. The setting is made to display in the area, and the process ends. In the round start process, information indicating the number of times the variable winning opening 130 is opened after the jackpot start included in the unprocessed command is extracted and stored in the storage area of the RAM 408.

Next, the sub-control unit variable update interrupt process executed by the CPU 404 of the sub-control unit 400 will be described with reference to FIG. This figure is a flowchart showing the flow of the sub-control unit variable update interrupt process.

  The sub-control unit 400 includes a hardware timer that generates a timer interrupt at a predetermined cycle (in this embodiment, once every 2 ms). With this timer interrupt, the sub-control unit timer interrupt processing is performed at a predetermined cycle. Run with.

  In step S901 of the sub-control unit variable update interrupt process, 1 is added to the value of the timer variable storage area of the RAM 408 and the result is stored in the original timer variable storage area. Therefore, in step S304, the value of the timer variable is determined to be 10 or more every 20 ms (2 ms × 10).

<Double checksum processing>
Next, double checksum processing performed in the pachinko machine 100 of the present embodiment will be described. In the double checksum process, in the RAM area inspection process (see step S105 in FIG. 10) executed when the power is turned on, a part of the RAM 308 of the main control unit 300 (for example, important data is stored). (Regarding the stored area) In a predetermined case (for example, when the entire checksum verification result is different), the checksum processing is executed twice, and based on the two inspection results, This is a process of executing initialization processing (not returning to the state before power interruption) and power recovery processing (returning to the state before power interruption). Specifically, as will be described later, the RAM area inspection is performed because it is determined which area of the RAM 308 data is initialized and which area data is to be restored based on the results of the two inspections. In addition to improving the reliability of the player, important data is restored as much as possible so as not to give a disadvantage to the player. Here, the important data includes, for example, information related to the game result (number of paid-out prize balls, gaming status, information related to errors, etc.) and information related to the player's profit (number of paid-out prize balls, gaming status, number of held balls, Information that would be detrimental to the player if the number of short-time games is cleared.

  FIG. 13 shows the relationship between each control unit (main control unit 300, sub-control unit 400, payout control unit 550, sub-control unit 500 (generally divided into an effect control unit and a liquid crystal control unit)) and the power management unit 650. It is a figure which shows the relationship of power supply. As shown in FIG. 13, the power management unit 650 supplies power to each control unit from the main power source when the power is turned on, and supplies power to each control unit from the backup power source when power is interrupted. Yes. The backup power source is a power storage circuit (for example, a capacitor) for supplying power for a predetermined period (for example, 10 days), and has a function of storing the contents of the RAM of each control unit when power is interrupted. That is, the contents of the RAM are not cleared within a predetermined period even if power interruption occurs.

  In the double checksum processing of the pachinko machine 100 having such a data backup mechanism, power-on processing (RAM area inspection processing; step S105 in FIG. 10), power-off processing (power-off processing; FIG. 11) This will be described in the following example.

(First embodiment)
<RAM area inspection processing>
FIG. 14 is a flowchart showing in detail the RAM area inspection process in step S105 of FIG. In the first embodiment, as shown in FIG. 16, the first area is changed from the entire RAM area of the RAM 308 (more precisely, from the entire RAM area for storing game information, the first checksum storage unit and the second The second area is a part of the RAM 308 (an area for storing information relating to the player's profit, such as a probability variation state storage unit and a payout request counter). That is, in the first embodiment, the second area is included in the first area, and the overlapping portion of the first area and the second area is the second area. The checksum related to the first area is stored in the first checksum storage unit as the first checksum, and the checksum related to the second area is stored as the second checksum in the second checksum storage unit. Is remembered.

  In step S1001, it is determined whether or not a RAM clear switch is detected. Specifically, whether or not the RAM clear signal transmitted when a store clerk or the like of the game shop operates the operation unit provided on the power supply board is on (indicating that there is an operation), that is, the RAM clear is Determine whether it is necessary. When the RAM clear switch is detected, the process proceeds to step S1008. When the RAM clear switch is not detected, the process proceeds to step S1002.

  In step S1002, the RAM total value of the first area of the RAM 308 is calculated as the first checksum. Specifically, a value calculated by adding 1-byte data stored in the entire RAM area of the RAM 308 is set as a first checksum.

  In step S1003, the first checksum calculated in step S1002 and the first checksum stored in the first checksum storage unit (the checksum of the first area calculated and stored at the time of power failure; this Are compared and determined in the process during power interruption). It is determined whether or not the data content stored in the first area has changed between power interruption and power on.

  In step S1004, when the check results of the two match in the determination result in step S1003, the process proceeds to step S1010. Otherwise, the process proceeds to step S1005.

  In step S1005, the total RAM value of the second area of the RAM 308 is calculated as the second checksum. Specifically, a value calculated by adding 1-byte data stored in a partial specific area of the RAM 308 is set as a second checksum.

  In step S1006, the second checksum calculated in step S1005 and the second checksum stored in the second checksum storage unit (the checksum of the second area calculated and stored at the time of power failure; this Are compared and determined in the process during power interruption). It is determined whether or not the data content stored in the second area has changed between power interruption and power on.

  In step S1007, when the check results of the two match in the determination result in step S1006, the process proceeds to step S1009. Otherwise, the process proceeds to step S1008.

  In step S1008, the first area of the RAM 308 is initialized. That is, when the RAM clear switch is detected, the entire RAM area of the RAM 308 is cleared. If the checksums of the first area and the second area do not match, the entire RAM area of the RAM 308 is cleared. This is because the check sum of the entire RAM area does not match and the check sum of the area storing particularly important data also does not match, so the identity of the contents of the RAM (particularly in the area storing important data) It is determined that the content is not secured, and the entire RAM 308 is cleared.

  In step S1009, the first area (see FIG. 16) excluding the second area is initialized. In other words, the checksums of the first area did not match, but when the checksums of the second area match, the identity of the content is guaranteed for the second area with the matching checksum. Therefore, the state before the power interruption is restored, and the other areas are initialized because the identity of the contents is not ensured. Thereby, since the information regarding the profit of the player is not cleared, even in such a case, the player does not suffer a disadvantage.

  In step S1010, the state before power interruption is restored. In other words, since the check sums of the first area match, it is determined that the content of the entire RAM area is identical, and the process is resumed in the state of the RAM 308 before power interruption.

  Thus, in the RAM area inspection process of the first embodiment, the second area is inspected based on the inspection result of the first area. Even if the checksums of the first area do not match, if the second checksums match, the second area can be returned to the state before the power interruption. Even if it is determined that the identity of the data contents is not secured, important data for the player is not cleared, and there is no disadvantage to the player.

  Also, factors that do not match the checksum include abnormal voltage generation due to lightning strikes, static electricity, etc., abnormal storage of RAM due to power reduction of the backup power supply that occurs because power is not supplied to the game machine for a predetermined period, etc. These usually don't happen very often. In the present embodiment, if it is normal, it recovers from the power interruption by a single inspection. Therefore, for example, an overlapping area is not provided, and a configuration in which high-priority data and low-importance data are separately inspected is used. The time required for the inspection of the RAM area can be shortened.

<Processing during power interruption>
FIG. 15 is a flowchart showing in detail the power interruption process in step S220 of FIG.

  In step S1101, the value of each register is saved in the RAM 308.

  In step S1102, the RAM total value of the first area of the RAM 308 is calculated as the first checksum. Specifically, a value calculated by adding 1-byte data stored in the entire RAM area of the RAM 308 is set as a first checksum.

  In step S1103, the first checksum calculated in step S1102 is stored in the first checksum storage unit of the RAM 308.

  In step S1104, the RAM total value of the second area of the RAM 308 is calculated as the second checksum. Specifically, a value calculated by adding 1-byte data stored in a partial specific area of the RAM area of the RAM 308 is set as the second checksum.

  In step S1105, the second checksum calculated in step S1104 is stored in the second checksum storage unit of the RAM 308.

  As described above, in the power interruption process of the first embodiment, not only the checksum of the first area but also the checksum of the second area is stored. Checksum processing can be performed, and the RAM area can be checked more accurately.

  From the above, according to the double checksum processing of the first embodiment, in addition to the determination result of the checksum processing of the entire RAM area of the RAM 308 of the main control unit 300, the checksum processing of a specific RAM area is also performed. The inspection related to the RAM area can be performed more accurately. Even if the checksums of the entire RAM area do not match, if the checksum of the specific RAM area in which the data related to the player's profit matches, the specific RAM area is not initialized. Since the state before the power interruption is restored, the player is not disadvantaged even in such a case.

  Various variations can be considered for the double checksum processing (RAM area inspection processing) of the first embodiment. That is, there are various variations as to what action should be taken based on the determination result of the two checksums. A modification of the RAM area inspection process according to the first embodiment will be described below. In the modification described below, only the RAM area inspection process is different, and the power interruption process is the same as that of the first embodiment, and thus the description of the power interruption process is omitted.

(Modification 1)
FIG. 17 is a flowchart illustrating the RAM area inspection process according to the first modification.

  In step S1201, it is determined whether or not a RAM clear switch is detected. When the RAM clear switch is detected, the process proceeds to step S1210. When the RAM clear switch is not detected, the process proceeds to step S1202.

  In step S1202, the RAM total value of the first area of the RAM 308 is calculated as the first checksum. Specifically, a value calculated by adding 1-byte data stored in the entire RAM area of the RAM 308 is set as a first checksum.

  In step S1203, the first checksum calculated in step S1202 and the first checksum stored in the first checksum storage unit (the checksum of the first area calculated and stored at the time of power interruption) are stored. Judge by comparison. It is determined whether or not the data content stored in the first area has changed between power interruption and power on.

  In step S1204, if both checksums match in the determination result in step S1203, the process proceeds to step S1211. Otherwise, the process proceeds to step S1205.

  In step S1205, the total RAM value of the second area of the RAM 308 is calculated as the second checksum. Specifically, a value calculated by adding 1-byte data stored in a partial specific area of the RAM 308 is set as a second checksum.

  In step S1206, the second checksum calculated in step S1205 and the second checksum stored in the second checksum storage unit (the checksum of the second area calculated and stored at the time of power failure) are stored. Judge by comparison. It is determined whether or not the data content stored in the second area has changed between power interruption and power on.

  In step S1207, when the checksums of the two match in the determination result in step S1206, the process proceeds to step S1210. Otherwise, the process proceeds to step S1208.

  In step S1208, error notification is performed. In other words, if the checksum and the second checksum of the first area do not match, there is a possibility of fraudulent acts on the second area related to the player's interest. , To ask for instructions from the store clerk of the amusement store.

  In step S1209, it is determined whether there has been an error cancel input. If there is an error cancel input, the process proceeds to step S1210. If not, step S1209 is repeated. That is, as long as there is no reset button operation by the game store clerk to cancel the error, the error notification is continued.

  In step S1210, the first area of the RAM 308 is initialized. That is, when the RAM clear switch is detected, the entire RAM 308 is cleared. If the checksums of the first area do not match, the entire RAM 308 is scanned regardless of the checksum result of the second area (whether or not the checksums of the second area match). clear. This is a stricter inspection than the RAM area inspection described in the first embodiment, and even if the checksums of the second area in which important data is stored match, Since the checksums do not match, it is determined that the data stored in the RAM 308 is not reliable data, and the entire RAM 308 is cleared.

  In step S1211, the state before power interruption is restored. In other words, since the check sums of the first area match, it is determined that the content of the entire RAM area is identical, and the process is resumed in the state of the RAM 308 before power interruption.

  As described above, in the RAM area inspection process according to the first modification, if the checksums of the first area do not match, it is determined that the data contents of the entire RAM area are not identical, so the second checksum. Regardless of the result, a strict inspection is performed to initialize the first region. Further, when the checksums of the second area do not match, an error notification is performed because there is a possibility of fraud in the area in which the information related to the player's profit is stored.

  From the above, according to the double checksum processing of the first modification of the first embodiment, in addition to the checksum processing for the entire RAM area of the RAM 308 of the main control unit 300, the checksum processing for a specific RAM area is also performed. In this way, it is possible to more accurately check the RAM area. In addition, since the inspection is performed more strictly than the double checksum processing described in the first embodiment, the reliability of the RAM area inspection processing can be further improved.

  In the first modification, when the first checksum does not match and the second checksum matches (step S1207: YES), the first area is initialized (step S1210). Instead of or in addition to the first initialization, error notification may be performed. A more rigorous inspection will be conducted, and in this case as well, an instruction from an amusement shop clerk will be requested.

(Modification 2)
FIG. 18 is a flowchart showing a RAM area inspection process according to the second modification of the present embodiment.

  In step S1301, it is determined whether or not a RAM clear switch is detected. If the RAM clear switch is detected, the process proceeds to step S1309. If the RAM clear switch is not detected, the process proceeds to step S1302.

  In step S1302, the RAM total value of the first area of the RAM 308 is calculated as the first checksum. Specifically, a value calculated by adding 1-byte data stored in the entire RAM area of the RAM 308 is set as a first checksum.

  In step S1303, the first checksum calculated in step S1302 and the first checksum stored in the first checksum storage unit (the checksum of the first area calculated and stored during power interruption) are stored. Judge by comparison. It is determined whether or not the data content stored in the first area has changed between power interruption and power on.

  In step S1304, when the checksums of the two match in the determination result in step S1303, the process proceeds to step S1305. Otherwise, the process proceeds to step S1309.

  In step S1305, the RAM total value of the second area of the RAM 308 is calculated as the second checksum. Specifically, a value calculated by adding 1-byte data stored in a partial specific area of the RAM area of the RAM 308 is set as the second checksum.

  In step S1306, the second checksum calculated in step S1305 and the second checksum stored in the second checksum storage unit (the checksum of the second area calculated and stored at the time of power failure) are stored. Judge by comparison. It is determined whether or not the data content stored in the second area has changed between power interruption and power on.

  In step S1307, if both checksums match in the determination result in step S1306, the process proceeds to step S1308; otherwise, the process proceeds to step S1309.

  In step S1308, the state before power interruption is restored. That is, since the check sum of the first area and the check sum of the second area match, it is determined that the same content in the entire RAM area and the same in the specific area are secured. The processing is resumed in the state of the RAM 308.

  In step S1309, the first area of the RAM 308 is initialized. That is, when the RAM clear switch is detected, the entire RAM 308 is cleared. If the checksums of the first area do not match, the entire RAM 308 is cleared. This is because the checksums of the entire RAM area do not match, and therefore, it is determined that the identity of the contents of the RAM is not secured and the entire RAM 308 is cleared. If the checksums of the second area do not match, the entire RAM 308 is scanned regardless of the checksum result of the first area (whether or not the checksums of the first area match). clear. This is a stricter inspection than the RAM area inspection described in the first embodiment. If the checksum of the second area in which important data is stored does not match, an illegal act on this area will not occur. Since it can be considered, the entire RAM 308 is cleared.

  As described above, in the RAM area inspection process of the second modification, only when both the checksum of the first area and the second checksum match, the state before power interruption is restored, and in other cases, A strict inspection is performed to initialize the first area.

  As described above, according to the double checksum process of the second modification of the first embodiment, in addition to the checksum process for the entire RAM area of the RAM 308 of the main control unit 300, the checksum process for a specific RAM area is also performed. In this way, it is possible to more accurately check the RAM area. In addition, since the inspection is performed more strictly than the double checksum processing described in the first embodiment, the reliability of the RAM area inspection processing can be further improved.

(Second embodiment)
Next, the double checksum process of the second embodiment will be described. FIG. 19 is a flowchart showing the RAM area inspection process of the second embodiment. In the second embodiment, only the RAM area inspection process is different, and the power interruption process is the same as that of the first embodiment, and therefore the description of the power interruption process is omitted. Further, in the second embodiment, as shown in FIG. 20, the first area is stored in a part of the RAM 308 (specifically, information related to a special figure such as a special figure holding number storage unit and a special figure game state storage unit is stored. Area P1 and area P2 for storing information not related to the usual figure / special drawing, such as a time-saving state storage unit and a time-saving game number storage unit), and the second area is a partial area of the RAM 308 (details) Stores an area P3 for storing information related to the general figure such as the general figure hold number storage part and the general figure game state storage part, and information related to the general figure and special figure such as the short time state storage part and the short time game number storage part. It is composed of a region P2. That is, in the second embodiment, both the first area and the second area have a part of the area (area P2) as an overlapping part, and the first area and the second area make the entire RAM area (exactly accurate). Constitutes a portion excluding the first checksum storage unit and the second checksum storage unit from the entire RAM area). The checksum related to the first area is stored in the first checksum storage unit as the first checksum, and the checksum related to the second area is stored as the second checksum in the second checksum storage unit. Is remembered.

  In step S1401, it is determined whether or not a RAM clear switch is detected. If the RAM clear switch is detected, the process proceeds to step S1408. If the RAM clear switch is not detected, the process proceeds to step S1402.

  In step S1402, the RAM total value in the first area of the RAM 308 is calculated as the first checksum. Specifically, a value calculated by adding 1-byte data stored in some areas P1 and P2 of the RAM 308 is set as a first checksum.

  In step S1403, the first checksum calculated in step S1402 and the first checksum stored in the first checksum storage unit (the checksum of the first area calculated and stored during power interruption) are stored. Judge by comparison. It is determined whether or not the data content stored in the first area has changed between power interruption and power on.

  In step S1404, the total RAM value of the second area of the RAM 308 is calculated as the second checksum. Specifically, a value calculated by adding the 1-byte data stored in the partial areas P2 and P3 of the RAM 308 is set as the second checksum.

  In step S1405, the second checksum calculated in step S1404 and the second checksum stored in the second checksum storage unit (the checksum of the second area calculated and stored at the time of power failure) are obtained. Judge by comparison. It is determined whether or not the data content stored in the second area has changed between power interruption and power on.

  In step S1406, when both the first checksum and the second checksum match, the process proceeds to step S1410. Otherwise, the process proceeds to step S1407.

  In step S1407, when either one of the first checksum and the second checksum matches, the process proceeds to step S1409, and both the first checksum and the second checksum do not match. If YES, go to step S1408.

  In step S1408, the first area and the second area of the RAM 308 are initialized. That is, when the RAM clear switch is detected, the entire RAM area of the RAM 308 is cleared. If the checksums of the first area and the second area do not match, the entire RAM area of the RAM 308 is cleared. This is because the check sum of the entire RAM area does not match and the check sum of the area storing particularly important data also does not match, so the identity of the contents of the RAM (particularly in the area storing important data) It is determined that the content identity is not secured, and the entire RAM 308 is cleared.

  In step S1409, the RAM area of the RAM 308 is initialized except for the area where the checksums match. That is, when the checksum of the first area matches, the RAM area excluding the first area is initialized, and when the checksum of the second area matches, the RAM area excluding the second area is initialized. To do. The area where the checksums match is determined to have the same content, and the area returns to the state before the power interruption. Therefore, the overlapping area (common area) P2 is returned to the state before power interruption if either the checksum of the first area or the checksum of the second area matches.

  In step S1410, the state before power interruption is restored. That is, since both the checksum of the first area and the checksum of the second area match, it is determined that the content of the entire RAM area is identical, and the state of the RAM 308 before power interruption is determined. Resume processing.

  Thus, in the RAM area inspection process of the second embodiment, the RAM 308 is inspected twice, that is, the first area and the second area. When the checksums of the first area match, the RAM area excluding the first area is initialized, and when the checksums of the second area match, the RAM area excluding the second area is initialized. Therefore, the area where the checksums match can be restored to the state before the power interruption.

  From the above, according to the double checksum processing of the second embodiment, the checksum processing of one specific area of the RAM 308 of the main control unit 300 and the other specific area partially overlapping with one specific area. Since the checksum process is performed, it is possible to more accurately check the RAM area.

  Note that the configurations of the first and second modifications may be adopted for the second embodiment as well as the first embodiment.

(Third embodiment)
Next, the double checksum process of the third embodiment will be described. In the third embodiment, not only the RAM area of the main control unit 300 is inspected, but the RAM area is inspected across two control boards (main control unit 300 and payout control unit 550). . In the third embodiment, as shown in FIG. 26, the first area is divided into the entire RAM area of the RAM 308 and the entire RAM area of the payout control unit 550 (more precisely, the first area from the entire RAM area of the payout control unit 550). And the second area is the entire RAM area of the RAM 308. That is, in the third embodiment, the second area is included in the first area, and the overlapping portion of the first area and the second area is the second area. The checksum related to the first area is stored in the first checksum storage unit provided in the RAM of the payout control unit 550 as the first checksum, and the checksum related to the second area is the second checksum. A checksum is stored in a second checksum storage unit (included in the first area) provided in the RAM of the payout control unit 550.

  In the third embodiment, the case where the RAM area is inspected across the two control boards of the main control unit 300 and the sub control part 550 will be described. However, the RAM area is inspected across the two control boards. The combination is not limited to this, and may be a combination of two other control boards. For example, a combination of the main control unit 300 and the sub control unit 400 or a combination of the sub control unit 400 and the sub control unit 500 may be used.

<Processing of main control unit>
FIG. 21 is a flowchart showing power interruption processing (corresponding to step S220 in FIG. 11) of the main control unit 300 of the third embodiment.

  In step S1501, the value of each register is saved in the RAM 308.

  In step S1502, the RAM total value of the second area is calculated as the second checksum. Specifically, a value calculated by adding 1-byte data stored in the entire RAM area of the RAM 308 is set as the second checksum.

  In step S1503, the second checksum calculated in step S1502 is transmitted to the payout control unit 550. This is because the second checksum is stored in the second checksum storage unit provided in the RAM area of the payout control unit 550 as described above.

  As described above, in the power interruption process of the main control unit 300 according to the third embodiment, unlike the above embodiment, the second checksum is transmitted to the payout control unit 550 and is not stored in the RAM 308 of the main control unit 300. .

  FIG. 22 is a flowchart showing the RAM area inspection process (corresponding to step S105 of FIG. 10) of the main control unit 300 of the third embodiment.

  In step S1601, it is determined whether a RAM clear switch is detected. When the RAM clear switch is detected, the process proceeds to step S1606. When the RAM clear switch is not detected, the process proceeds to step S1602.

  In step S1602, the RAM total value of the second area is calculated as the second checksum. Specifically, a value calculated by adding 1-byte data stored in the entire RAM area of the RAM 308 is set as the second checksum.

  In step S1603, the second checksum calculated in step S1602 is transmitted to the payout control unit 550. This is because the second checksum storage unit is provided in the RAM area of the payout control unit 550 and the second checksum comparison / determination process is performed by the payout control unit 550 in this embodiment.

  In step S1604, it is determined whether a RAM clear command has been received from the payout control unit 550. The RAM clear command is a command for initializing the entire RAM area of the RAM 308 of the main control unit 300. When the RAM clear command is received, the process proceeds to step S1606. When the RAM clear command is not received, the process proceeds to step S1605.

  In step S1605, it is determined whether a return command has been received from the payout control unit 550. The return command is a command for restarting the process in the state before the power interruption of the RAM 308 of the main control unit 300. When the return command is received, the process proceeds to step S1607. When the return command is not received, the process returns to step S1604.

  In step S1606, the second area is initialized. That is, when the RAM clear switch is detected, the entire RAM area of the RAM 308 is cleared. When the RAM clear command is received from the payout control unit 550, the entire RAM area of the RAM 308 is cleared. This is because a RAM clear command indicating that the checksums in the second area do not match is received from the payout control unit 550 that has performed the second checksum comparison determination process (details will be described later).

  In step S1607, the state before power interruption is restored. That is, when a return command is received from the payout control unit 550, the entire RAM area of the RAM 308 is set to the state before power interruption, and the process is resumed. This is because a return command indicating that the checksums in the second area match is received from the payout control unit 550 that has performed the second checksum comparison determination process (details will be described later).

  As described above, in the RAM area inspection process of the main control unit 300 of the third embodiment, unlike the above-described embodiment, the second checksum comparison determination process (check process) is not executed in the main control unit 300. That is, the second checksum is calculated and transmitted to the sub-control unit 550, and initialized based on a command based on the second checksum comparison determination process executed by the payout control unit 550, or Decide whether to return.

<Processing of payout control unit>
FIG. 23 is a flowchart showing main processing of the payout control unit 550 of the third embodiment. The payout control unit 550 is provided with a reset signal output circuit that outputs a reset signal when the power is turned on. The CPU of the basic circuit to which this reset signal is input starts reset by a reset interrupt and executes processing in accordance with a control program stored in advance in the ROM.

  In step S1701, initial setting 1 is performed. In the initial setting 1, a stack initial value is set in the stack pointer (SP) of the CPU.

  In step S1702, whether or not the low voltage signal is ON, that is, the voltage value of the power supply that the voltage monitoring circuit supplies from the power supply management unit 650 to the payout control unit 550 is a predetermined value (9v in this embodiment). ), It is monitored whether or not a low voltage signal indicating that the voltage has dropped is output. If the low-voltage signal is on (when power-off is detected), step S1702 is repeated. If the low-voltage signal is off (when power-off is not detected), step S1702 is performed. The process proceeds to S1703.

  In step S1703, initial setting 2 is performed. In this initial setting 2, processing for setting a value for determining a cycle for executing the payout control unit timer interrupt processing at regular intervals in the counter / timer, setting for permitting writing to the RAM, initial setting for the I / O port, etc. I do.

  In step S1704, RAM area inspection processing is performed. In this RAM area inspection process, the RAM area is inspected to determine whether or not to return to the state before the power is shut off (before the power interruption). Specifically, a checksum is calculated by adding all 1-byte data stored in a predetermined area (for example, all areas) of the RAM of the payout control unit 550 to a 1-byte register, and the calculated check Whether or not the result of the sum matches the checksum calculated and stored at the time of power failure is determined as to whether the contents of the RAM are the same, and whether or not the state before power failure is restored is determined.

  When the state before power interruption is not restored (when the basic circuit of the dispensing control unit 550 is set to the initial state), initialization processing is performed. In the initialization process, interrupt prohibition setting, stack initial value setting for the stack pointer, initialization of all storage areas of the RAM, and the like are performed. Further, when returning to the state before the power interruption, a power recovery process is performed. In the power recovery process, the stack pointer stored in the stack pointer save area provided in the RAM at the time of power failure is read and reset to the stack pointer. In addition, the value of each register stored in the register save area provided in the RAM at the time of power interruption is read, and after resetting to each register, interrupt permission is set. The RAM area inspection process in step S1704 will be described later in detail.

  In step S1705, initial setting 3 is performed. In the initial setting 3, information other than the illegal payout error and the payout excess error among the error statuses stored in the error status storage area provided in the RAM is cleared, interrupt permission is set, and the like.

  In step S1706, it is determined whether or not there is unanalyzed data in the data input from the main control unit 300. If there is unanalyzed data, command analysis processing is performed in step S1707, and there is no unanalyzed data. Then, the process proceeds to step S1708.

  In step S1708, it is monitored whether or not the low-voltage signal is off. If the low-voltage signal is off (when power-off is not detected), the process returns to step S1706, and the low-voltage signal is on. In the case of detecting a power shutdown, the process proceeds to step S1709.

  In step S1709, a power interruption process is performed. That is, the voltage monitoring circuit that monitors the voltage value of the power supplied from the power management unit 650 to the payout control unit 550 outputs a voltage drop signal indicating that the voltage has dropped when the voltage is less than a predetermined value. Whether or not power-off is detected, and if power-off is detected, return a specific variable or stack pointer to return to the power-off state when power is restored Are saved in a predetermined area of the RAM, and power interruption processing such as initialization of the input / output port is performed. The power interruption process in step S1709 will be described in detail later.

  In step S1710, it is monitored whether or not the low voltage signal is on. When the low voltage signal is on (when power-off is detected), the process of step S1710 is repeatedly executed to turn off the low voltage signal. When the low-voltage signal is off (when power-off is not detected), the process returns to step S1701 to start the payout control unit main process from the beginning. That is, in step S1710, after the low voltage signal is input in step S1708 (after detecting the power supply shutoff), it is detected that the output of this low voltage signal has stopped (when the power supply is detected to be restored). ) Performs initialization processing for initializing the payout control circuit 402.

  FIG. 24 is a flowchart showing in detail the RAM area inspection processing in step 1704 of FIG.

  In step S1801, it is determined whether a RAM clear switch has been detected. When the RAM clear switch is detected, the process proceeds to step S1813. When the RAM clear switch is not detected, the process proceeds to step S1802.

  In step S1802, it is determined whether the second checksum is received from the main control unit 300 (see step S1603 in FIG. 22). When the second checksum is received from the main control unit 300, the process proceeds to step S1803. Otherwise, step S1802 is repeated. Note that the reception of the second checksum is performed in the command reception interrupt process shown in FIG. In the command reception interrupt process, the information received from the main control unit 300 in step S2001 (information regarding the number of payout requests; the second checksum is also included) is stored.

  In step S1803, the RAM total value of the first area excluding the second area is calculated. Specifically, the RAM total value is calculated by adding 1-byte data stored in the entire RAM area of the payout control unit 550 (exactly, the first checksum storage unit is excluded).

  In step S1804, the first checksum is calculated by adding the second checksum received in step S1802 and the RAM total value calculated in step S1803.

  In step S1805, the first checksum calculated in step S1804 and the first checksum stored in the first checksum storage unit (the checksum of the first area calculated and stored at the time of power failure; this Are compared and determined later in the process during power interruption of the payout control unit 550). It is determined whether or not the data content stored in the first area has changed between power interruption and power on.

  In step S1806, if both checksums match in the determination result in step S1805, the process proceeds to step S1807, and if not, the process proceeds to step S1808.

  In step S1807, the state before power interruption is restored. That is, since the checksums of the first area match, it is determined that the content of the entire RAM area of the payout control unit 550 is secured, and the process of the payout control unit 550 is performed in the state of the RAM before power interruption. To resume.

  In step S1808, the second checksum received in step S1802 and the second checksum stored in the second checksum storage unit (the checksum of the second area calculated and stored at the time of power failure; this Are compared and determined later in the process during power interruption of the payout control unit 550). It is determined whether or not the data content stored in the second area has changed between power interruption and power on.

  In step S1809, if the checksums of the two match in the determination result in step S1808, the process proceeds to step S1010, and if not, the process proceeds to step S1812.

  In step S1810, the first area (see FIG. 26) excluding the second area is initialized. That is, when the checksums of the first area do not match, even if the checksums of the second area match, the first area excluding the second area is initialized. In this case, since it can be determined that the content of the first area excluding the second area, that is, the RAM area of the payout control unit 550 is not secured, the RAM area of the payout control unit 550 is initialized. Is.

  In step S1811, a return command is transmitted to the main control unit 300. That is, when the checksums in the first area match, a return command is transmitted to the main control unit 300. In addition, the checksums of the first area do not match, but when the checksums of the second area match, a return command is transmitted to the main control unit 300. In any case, it can be determined that the identity of the contents of the second area, that is, the RAM area of the main control unit 300 is secured.

  In step S1812, the first area excluding the second area (see FIG. 26) is initialized. That is, when the check sum of the first area does not match and the check sum of the second area does not match, the first area excluding the second area is initialized. In this case, since it can be determined that the content of the first area excluding the second area, that is, the RAM area of the payout control unit 550 is not secured, the RAM area of the payout control unit 550 is initialized. Is.

  In step S1813, a RAM clear command is transmitted to main controller 300. That is, when the check sums of the first area do not match and the check sums of the second area do not match, a RAM clear command is transmitted to the main control unit 300. This is because it can be determined that the identity of the contents of the second area, that is, the RAM area of the main controller 300 is not secured.

  Thus, in the RAM area inspection process of the payout control unit 550 of the third embodiment, the RAM areas of the main control unit 300 and the payout control unit 550 are inspected, and the RAM area of the main control unit 300 is also inspected. At this time, the main control unit 300 does not perform the checksum processing (checksum comparison / determination processing) of the RAM area of the main control unit 300 to the payout control unit 550, and therefore the main control unit 300 does not start when the power is turned on. Can be made faster.

  FIG. 25 is a flowchart showing in detail the power interruption process in step 1709 of FIG.

  In step S1901, it is determined whether the second checksum has been received from the main control unit 300 (see step S1503 in FIG. 21). If the second checksum is received from the main control unit 300, the process proceeds to step S1902, and if not, step S1901 is repeated. Note that the reception of the second checksum is performed in the command reception interrupt process shown in FIG. In the command reception interrupt process, the information received from the main control unit 300 in step S2001 (information regarding the number of payout requests; the second checksum is also included) is stored.

  In step S1902, the second checksum received in step S1901 is stored in the second checksum storage unit.

  In step S1903, the RAM total value of the first area excluding the second area is calculated. Specifically, the RAM total value is calculated by adding 1-byte data stored in the entire RAM area of the payout control unit 550 (exactly, the first checksum storage unit is excluded).

  In step S1904, the first checksum is calculated by adding the second checksum received in step S1901 and the RAM total value calculated in step S1903.

  In step S1905, the first checksum calculated in step S1904 is stored in the first checksum storage unit.

  As described above, in the power interruption process of the payout control unit 550 of the third embodiment, the checksum of the first area and the checksum of the second area are also stored. That is, since the checksum of the entire RAM area of the main control unit 300 and the checksum of the entire RAM area including the main control unit 300 and the payout control unit 550 are stored, in the RAM area inspection process at power-on, Checksum processing can be performed, and the RAM area can be checked more accurately.

  From the above, according to the double checksum processing of the third embodiment, the checksum processing of the entire RAM area of the main control unit 300 and the checksum processing of the entire RAM area combining the main control unit 300 and the payout control unit 550 As a result, it is possible to more accurately inspect the RAM area across the two control boards. Further, even if the check sum of the entire RAM area including the main control unit 300 and the payout control unit 550 does not match, the entire RAM area of the main control unit 300 (data relating to the player's profit is also stored) is checked. If the thumbs match, the entire RAM area of the main control unit 300 is not initialized and the state before power interruption is restored, so that even in such a case, the player does not suffer a disadvantage.

  Note that the configuration of the first and second modifications may be adopted for the third embodiment as well as the first embodiment.

<Other embodiments>
As mentioned above, although embodiment of this invention has been described, various deformation | transformation and change can be performed with respect to embodiment of this invention in the range which does not deviate from the summary of this invention.

  For example, an inspection method different from the inspection method of the double checksum processing in the above embodiment may be used. As an example, the RAM area total value is calculated by adding all 1-byte data stored in a predetermined area (for example, all areas) of the RAM 308 to a 1-byte register at the time of power interruption. A value that becomes 256 (= 0; because a 1-byte register capable of storing 0 to 255) is combined with the total RAM area value may be stored in the checksum storage unit. Then, when the power is turned on, the RAM area total value is calculated, the calculated RAM area total value and the numerical value stored in the checksum storage unit are totaled, and whether or not the total numerical value is 256 (0), You may make it judge the identity of the content of RAM308. Further, the inspection method for the first region and the inspection method for the second region may be different. For example, the inspection method of the first area is the inspection method described in the above embodiment, and the inspection method of the second area is the checksum of the entire target RAM area including the data stored in the checksum storage unit. It is good also as the inspection method which becomes 0.

  In the above embodiment, the predetermined RAM area is checked twice, but it goes without saying that it may be checked in triple or quadruple as long as it is checked multiple times.

  In the above embodiment, the double checksum processing is performed at the time of power interruption and power-on, but the execution time is not limited to this. For example, when information is transmitted from a first control unit (for example, a main control unit) to a second control unit (for example, a sub-control unit), the information is stored after the second control unit receives and stores the information. There is a case where information stored due to noise or the like changes before the determination and an error occurs. In order to avoid such a situation, a configuration in which the checksum of the storage area at the time of reception is stored and the received information is verified by comparison with the checksum calculated at the time of determination can be considered. It may be applied in the configuration.
