The jackpot random number counter is used for jackpot determination by the hit determination means, and consists of numerical values (0) to "629" (jackpot random number). The value of the jackpot random number counter (jackpot random number) starts from “0” when the gaming machine is turned on, and is incremented by 1 for each of the normal symbol / special symbol main random number update processing described later. Is set to “0” and the addition is repeated again. The jackpot random number is acquired due to winning at the start winning opening 42, and if the acquired value matches one of '77' and '78' set as the jackpot success value in the low probability state, the jackpot is random. On the other hand, in the high probability state, if it matches any one of “77” to “96” set as the jackpot value, it is a jackpot.

  The jackpot symbol random number counter determines a jackpot symbol combination that is confirmed and stopped in the special symbol display unit 11 when the jackpot winning / failing determination result is a hit, and is a numerical value of “0” to “8” ( Jackpot symbol random number). The value of the jackpot symbol random number counter (jackpot symbol random number) is incremented by 1 every time a normal symbol / special symbol main random number update process described later starts from “0” when the power is turned on. It is set to “0” and the addition is repeated again. The jackpot symbol random number is acquired due to winning at the start winning opening 42. The jackpot symbol random number is assigned a jackpot symbol combination that is stopped and displayed on the special symbol display unit 11 when the jackpot winning / failing determination result is a hit. In the present embodiment, when it is “0”, it is one grove (all the same symbols) where the jackpot symbol combination is “1,1,1”, and when it is “1”, it is “2,2,2”. 2 slots, if '2', 3 slots, '3, 3, 3'; if '3', 4 slots, '4, 4, 4' 5 for eyes, 4 for 5 and 5 for 5; 6 for 6; 6, 6 for 6; 7 in the case of '7,7,7', 8 in the case of '7', 8 in the case of '8,8,8', A jackpot symbol combination consisting of 9 slots 9 and 9 'is assigned.

  The reach random number counter is used for determining whether or not a reach state is reached when the jackpot determination result of the jackpot random number is out of reach, and is a numerical value of “0” to “126” ( Reach random number). The reach state in the present embodiment excludes the special symbol (for example, the middle special symbol) that is stopped and displayed last among the left special symbol, the middle special symbol, and the right special symbol that are displayed with the variable symbol stopped on the special symbol display unit 11. When other special symbols (for example, left special symbol and right special symbol) are the same (excluding the final stop symbol, the state is equal to the jackpot special symbol combination, and finally the jackpot special symbol combination) And a case where a special symbol combination is included. The random number of the reach random number counter (reach random number) starts from “0” when the gaming machine 1 is turned on, and is incremented by 1 every time a normal symbol / special symbol main random number update process described later is performed. Then, it is set to “0” and the addition is repeated again. The reach random number is acquired due to winning at the start winning opening 42, and when the result of the determination is wrong, the numerical value is compared with a predetermined reach establishment value to determine the presence or absence of reach. In this embodiment, reach establishment values are “5”, “17”, “28”, “40”, “51”, “63”, “74”, “86”, “97”, “109”, “ 120 '.

  The special symbol data random number counter is used for determining a special symbol combination to be stopped and displayed on the special symbol display unit 11 when the jackpot determination result based on the jackpot random number value is out, The special symbol data 1 random number counter for determining the left special symbol to be stopped and displayed on the display unit 11, the special symbol data 2 random number counter for determining the middle special symbol, and the special symbol data 3 for determining the right special symbol. Each special symbol data random number counter is composed of numerical values (random numbers) from “0” to “8”.

The random number of the special symbol data 1 starts from “0” when the power is turned on, and is incremented by “1” every time the normal symbol / special symbol main random number update process described later is performed. And the addition is repeated again. The random number of the special symbol data 2 starts from “0” when the power is turned on, and is incremented by “1” when the random number of the special symbol data 1 is rewritten to “0”, and reaches “8”. Then, it is rewritten to “0” and the addition is repeated again. Further, the random number of the special symbol data 3 starts from “0” when the power is turned on or after the reset process, and is incremented by “1” when the random number of the special symbol data 2 is rewritten to “0”. When it reaches', then it is rewritten to '0' and the addition is repeated again. Thereby, even if the random number ranges of the special symbol data 1 to 3 are the same, the random numbers of the special symbol data 1 to 3 can be prevented from being synchronized (added in the same combination).

  Each of the random numbers of the special symbol data 1 to 3 is “1” when “0”, “2” when “1”, and “3” when “2”. Identification information including a left special symbol, a middle special symbol, and a right special symbol that are stopped and displayed on the display unit 11 is assigned. The random numbers of the special symbol data 1 to 3 are acquired due to winning at the start winning opening 42, and the special symbol display unit 11 is stopped when the special symbol data 1 to 3 is lost due to the combination of the random numbers of the acquired special symbol data 1 to 3. The left special symbol, middle special symbol, and right special symbol to be displayed are determined.

  The variation mode random number counter is used when the variation mode of the special symbol in the special symbol display unit 11 is selected from the variation mode table, and includes a numerical value (variation mode random number) of “0” to “198”. . The random number of the variation mode starts from “0” when the gaming machine 1 is turned on, and is incremented by 1 every time a normal symbol / special symbol main random number update process to be described later is reached. It is set to 0 'and the addition is repeated again. The numerical value (variation mode random number) of the variation mode random number counter is acquired due to winning at the start winning opening 42.

  The variation mode table of the present embodiment includes a first variation mode table that is selected when the determination result is a win and a second variation mode table that is selected when the determination result is incorrect. Each variation mode table includes a plurality of variations of the special symbol displayed on the special symbol display unit 11 and is stored in the ROM of the main control board 200. In each variation mode, a variation mode random value (a numerical value of the variation mode random number counter) is set, and a variation mode random value (for variation mode random number) corresponding to the variation mode random value acquired from the variation mode random number counter is set. The variation mode in which the value of the counter) is set is selected. In addition, a variation time is set for each variation mode, and the special symbol varies in the special symbol display unit 11 according to the variation time set for the selected variation mode.

  The obtained random numbers are stored in the corresponding areas in the RAM of the main control board 200 in correspondence with the number of reserved balls and used sequentially.

The normal symbol random number counter is used for determination per ordinary symbol, and when the gaming machine 1 is turned on, it starts from “0” and is incremented by “1” for each of the normal symbol / special symbol main random number update processing described later, When it reaches “9”, it is rewritten to “0” and the addition is repeated again. The numerical value of the normal symbol random number counter (ordinary symbol random number) is acquired by detecting the game ball that has passed through the normal symbol variation starting gates 55 and 56 with the normal symbol variation starting switch. When the value of the acquired normal symbol random number is an odd number, it is per normal symbol, and when the value is an even number, it is off. In addition, a symbol that is stopped and displayed on the normal symbol display unit 50 is assigned to the normal symbol random number. For example, a normal symbol that is stopped and displayed on the normal symbol display unit 50 is assigned to the normal symbol random number “0”, such as the normal symbol “0”, and the normal symbol random number “1” to the normal symbol “1”. Yes.

  The control by the main control board 200 will be described. As main flags provided on the main control board (main control circuit) 200, in this embodiment, a big hit flag, a big hit end flag, a probability change flag, a power-off flag, and the like can be cited. These flags are all turned OFF at the time of initial setting.

  In the main control board 200, the CPU performs a main process M in accordance with a program stored in the ROM. FIG. 10 is a flowchart of the main process M.

  In the main process M, initial setting process (S10) of the CPU, abnormality determination of RAM contents (S20), RAM initialization process (S30), interrupt prohibition process (S40), normal symbol / special symbol main random number update Processing (S50) and interrupt permission processing (S60) are performed, and interrupt processing (S100) is executed every 4 ms while loop processing is performed in the final processing.

  In the initial setting process (S10) of the CPU and the like, stack setting, interrupt time setting, CPU setting, SIO, PIO, CTC setting and the like are performed. Next, it is determined whether or not the RAM clear switch is ON, or whether or not the power-off flag is ON and the RAM contents are normal (S20). If it is determined abnormal, the RAM is initialized (S30). Although the main process M is repeatedly performed, the initial setting process (S10) of the CPU or the like, the RAM content abnormality presence / absence determination (S20), and the initialization of the RAM (S30) are the initial control procedures necessary only when the power is turned on. Yes, it is executed only in the first round, and not executed after that. However, since it is well known, the details are omitted. In the interrupt prohibition process (S40), even if the interrupt process (S100) is entered every 4 msec, the interrupt is prohibited until the interrupt is permitted. In the normal symbol / special symbol main random number update process (S50), various random numbers are added by 1 for each normal symbol / special symbol main random number update process (S50), and when the set upper limit value of each random number is reached as described above, Return to '0' and the addition is performed again. The updated random number is stored in the RAM of the main control board 200. In the interrupt permission process (S60), the interrupt process (S100) that enters every 4 msec is permitted.

  In the interrupt process (S100), as shown in FIG. 11, an output process (S110) is first performed. In the output process (S110), a command (control signal) or the like stored in the output buffer of the main control board 200 by each process is output to the corresponding control board or the like. The commands (control signals) and the like output here include jackpot symbol data, jackpot determination data, missed symbol data, variation commands, and the like. In the subsequent input process (S120), signal input is performed when various sensors (such as detection switches for each winning opening) detected in the gaming machine 1 are detected. In the next normal symbol / special symbol main random number update process (S130), the same process as the normal symbol / special symbol main random number update process (S50) performed in the loop process in the main process M is performed. .

  In the start winning opening switch detection process (S140), as shown in FIG. 12, first, whether or not a game ball has won the start winning opening 42, that is, there is a game ball entering the start winning opening 42 and the start is started. It is determined whether or not a game ball is detected by the winning opening detection switch (S140-1), and if the winning winning opening 42 has not been won, the start winning opening switch detection process (S140) is terminated. On the other hand, if the winning winning opening 42 has been won, it is next confirmed whether the number of reserved balls for special symbols stored in the RAM of the main control board 200 is four or more (S140-). 2). If the number of reserved balls for the special symbol is 4 or more, the start winning port switch detection process (S140) is terminated. If the number of reserved balls for the special symbol is less than 4, the start winning port switch is set to the number of reserved balls for the special symbol. The game ball detection number 1 detected in (1) is added (S140-3). Subsequently, a special symbol-related random number acquisition process (S140-4) is performed, and then the start winning a prize opening switch detection process (S140) ends. In the special symbol related random number acquisition process (S140-4), an updated random number related to the special symbol stored in the RAM is acquired, and the acquired random number is saved in the RAM address corresponding to the current number of reserved balls for special symbols ( Remembered). The random value acquired here is a jackpot random number value, a jackpot symbol random number value, a reach random number value, a special symbol data random value, a variation mode random number value, or the like. The acquired random number value is saved in the RAM address corresponding to the current number of reserved balls for special symbols. For example, when the number of reserved balls for special symbols is 1, this corresponds to the number of reserved balls for special symbols 1. The acquired random number value is saved in the RAM address to be stored. When the number of reserved balls for special symbol is 2, this means that the acquired random number value is saved in the RAM address corresponding to the number of reserved balls for special symbol 2.

  In the normal operation process (S150), the updated normal symbol random number stored in the RAM is acquired, the normal symbol per unit determination, the normal symbol stop display on the normal symbol display unit 50, and the start winning opening 42 are displayed. Although processing related to normal symbols such as opening and closing is performed, it is not important for understanding the present invention, and thus detailed description thereof is omitted.

In the special operation process (S160), as shown in FIG. 13, first, a special out symbol creation process (S160-1) is performed.
In the special off symbol creation process (S160-1), as shown in FIG. 14, the address value of the special symbol data 1 acquired in the start winning a prize opening switch detection process (S140) and stored in the RAM is the storage source address. Is set to a value (S160-1-1), and then the special symbol data 3 acquired in the start winning a prize opening switch detection process (S140) and stored in the RAM is loaded as a determination value (S160-1). -2), it is determined whether or not the random value of the special symbol data 3 as the determination value matches the random value of the special symbol data 1 stored in the storage source address value (S160-1-3). . If there is a match, the special out symbol design processing (S160-1) is completed and the special out symbol data is not updated. If they do not match, the data storage destination address value of the special out symbol in the RAM and the special out symbol are stored. Are set as the address values of the special symbol data 1 to 3 (S160-1-4), and the special symbol assigned to the random value of the special symbol data 1 to 3 is The special out symbol data is updated by being transferred to the data storage destination and stored as special out symbols 1 to 3 (S160-1-5), and then the special out symbol generating process (S160-1) is finished. . The special symbol 1 is stopped and displayed on the special symbol display unit 11 when the jackpot determination result is lost, and the special symbol 2 is stopped and displayed on the special symbol display unit 11 when the jackpot determination result is off. The middle special symbol and the special out symbol 3 correspond to the right special symbol which is stopped and displayed on the special symbol display unit 11 when the jackpot determination result is out.

  As shown in FIG. 13, in the special operation process (S160), it is determined whether the special operation status is 1 to 4 after the special out symbol creation process (S160-1) (S160-2 to 160). -4). When the special operation status is 1, a special symbol standby process (S160-5) is performed. On the other hand, when the special operation status is 2, a changing process (S160-6) is performed. When the operation status is 3, a special symbol confirmation process (S160-7) is performed, and when the operation status is 4, a special electric accessory process (S160-8) is performed.

  In the special symbol standby process (S160-5), as shown in FIG. 15, it is determined whether or not the number of reserved balls for special symbols is 0 (S160-5-1), and the number of reserved balls for special symbols is 0. In this case, it is determined whether or not the special symbol display unit 11 is on a standby screen (standby screen) where the special symbol is not changing (S160-5-7). When the symbol standby process (S160-5) is completed, but the standby screen (standby screen) is not in progress, a setting process for setting the special symbol display unit 11 to the standby screen (standby screen) is performed (S160-5). -8) After that, the special symbol standby process (S160-5) ends. In the setting process for setting the standby screen, a command for setting the standby screen is output to the sub-control board 205 when a game ball does not win the start winning opening 42 for a predetermined time after the setting process is performed. It is processing to do.

  On the other hand, if it is determined in S160-5-1 that the number of reserved balls for special symbols is not 0, special symbol jackpot determination processing (S160-5-2) is performed. In the special symbol jackpot determination process (S160-5-2), as shown in FIG. 16, first, the updated jackpot random number value stored in the RAM of the main control board 200 is loaded as a determination value (160-). Along with 5-2-1), the address of the RAM storing the jackpot determination value table that defines the jackpot value at the time of high probability and low probability is set (S160-5-2-2). Subsequently, it is determined whether or not the current probability change is in progress (high probability state) (S160-5-2-3). Whether or not the probability change is in progress is determined by whether the probability change flag provided on the main control board 200 is ON (high probability state) or OFF (low probability state). When the probability change is in progress, it is determined whether or not the jackpot is based on whether or not the jackpot value in the high probability state matches the loaded jackpot random value (S160-5-2-4). If it is not medium, that is, in the low probability state, whether or not the jackpot is established is determined by whether or not the jackpot value in the low probability state matches the loaded jackpot random number value (S160-5-2-5). Then, it is determined that a big hit is made, and the big hit flag provided on the main control board 200 is set to ON (S160-5-2-6). Thereafter, the special symbol jackpot determination process (S160-5-2) ends. If it is determined in S160-5-2-4 or S160-5-2-5 that there is no big hit, this special symbol big hit determination process (S160-5-2) without turning on the big hit flag. Ends.

  After the special symbol jackpot determination process (S160-5-2), a special symbol selection process (S160-5-3) is performed. In the special symbol selection process (S160-5-3), as shown in FIG. 17, it is determined whether or not the big hit flag is ON (big hit) (S160-5-3-1), and the big hit flag is ON (big hit). In this case, a symbol based on the jackpot symbol random number is set as a jackpot symbol to be stopped and displayed on the special symbol display unit 11 (S160-5-3-2), and then this special symbol selection process (S160- 5-3) ends.

  On the other hand, when the jackpot flag is OFF (disconnected), the reach random number value acquired in the start winning a prize opening switch detection process (S140) and stored in the RAM of the main control board 200 is loaded, and the reach It is confirmed whether or not it agrees with the established numerical value (S160-5-3-4), and if it agrees, there is a reach, and is acquired in the start winning a prize opening switch detection process (S140) and stored in the RAM of the main control board 200 The special symbol data 1 is set as the left and right special symbols to be stopped and displayed on the special symbol display unit 11 (S160-5-3-5), and then 1 is added to the special symbol data 1 (S160- 5-3-6), and the added one is set as a medium special symbol that is stopped and displayed on the special symbol display unit 11 (S160-5-3-7). Thereafter, the special symbol selection process (S160-5-3) is completed.

  On the other hand, when the loaded reach random number value does not coincide with the reach establishment value, that is, when it is determined that there is no reach, the special out symbol 1 to 1 created in the special out symbol creation process (S160-1). 3 is set (stored) as the storage source address value (S160-5-3-8), and then the special stop symbols 1 to 3 are set as the storage destination address value (S160). -5-3-9), data is transferred from the respective storage source addresses to the corresponding storage destination addresses (S160-5-3-10), and then this special symbol selection processing (S160-5-3) is completed. To do. The special stop symbol 1 is the left special symbol that is stopped and displayed on the special symbol display unit 11, the special stop symbol 2 is the middle special symbol that is stopped and displayed on the special symbol display unit 11, and the special stop symbol 3 is the special symbol. This corresponds to the right special symbol that is stopped and displayed on the display unit 11.

  Subsequent to the special symbol selection process (S160-5-3), a special symbol variation mode selection process (S160-5-4) is performed. In the special symbol variation mode selection process (S160-5-4), as shown in FIG. 18, it is determined whether the jackpot flag is ON (S160-5-4-1), and when the jackpot flag is ON (win) When the variation mode is selected from the first variation mode table based on the random number value of the variation mode (S160-5-4-2), on the other hand, when the jackpot flag is OFF (out), the second variation mode table is selected. Then, the variation mode is selected based on the random number value of the variation mode (S160-5-4-3), and thereafter, the other processing (S160-5-4-4) is performed, and this processing ends.

  Subsequent to the special symbol variation mode selection processing (S160-5-4), special symbol random number shift processing (S160-5-5) is performed. In this special symbol random number shift process (S160-5-5), in the data storage area for the number of reserved balls for special symbols in the RAM, for special symbols stored in the storage area of the address with the highest load (reading) order. Due to the fact that the data on the number of reserved balls is loaded and vacant due to the previous processing, the loading order of the data on the number of reserved balls for special symbols stored at the second and subsequent addresses is the same. The address is shifted up one by one. Specifically, as shown in FIG. 19, first, 1 is subtracted from the number of reserved symbols for special symbols stored in the RAM of the main control board 200 (for example, the number of reserved balls of 2 is set to 1 and 3 (S160-5-5-1), and then the data corresponding to each number of reserved balls is shifted to the RAM address of the number of reserved balls obtained by subtracting 1 from each number of reserved balls (S160). -5-5-2) Subsequently, 0 is set to the RAM address corresponding to the number of reserved balls for special symbols at the top (the last in the loading order, the fourth in this embodiment) (S160-5-5). -3).

  Following the special symbol random number shift process (S160-5-5), a special symbol variation start process (S160-5-6) is performed. In the special symbol variation start process (S160-5-6), the special operation status is set to 2 and other processing necessary for starting the variation of the special symbol is performed. After the special symbol variation start process (S160-5-6), the special symbol standby process (S160-5) ends.

  In the changing process (S160-6) performed when the special operation status is 2, as shown in FIG. 20, it is first determined whether or not the changing time of the special symbol has ended (S160-6-1). If the time has not ended, the changing process (S160-6) ends. On the other hand, if the fluctuation time is over, the variable stop symbol table is set (S160-6-2), and the variable stop symbol data is stored (S160-6-3), followed by the special operation status. Is set to 3 (S160-6-4), and after other necessary processing (S160-6-5) is performed, this in-fluctuation processing (S160-6) ends.

It is determined whether it is the opening time of the big prize opening 15 (S160-8-4). In the case of the opening time of the special winning opening 15, the opening process of the special winning opening is performed (S160-8-5), and then the special electric accessory processing (S160-8) is finished. On the other hand, when it is not the opening time of the special winning opening 15, this special electric accessory processing (S160-8) ends.

  On the other hand, if it is determined in S160-8-3 that the big prize opening 15 is open, ten game balls are won in the big prize opening 15 (S160-8-6) or the round end time (in this embodiment). 30 seconds) is determined (S160-8-7), and if it is none, the special electric accessory processing (S160-8) is terminated as it is, and a special prize opening is received. In the case where 10 game balls are won in 15 or the end of the round end time has elapsed, the special winning opening closing process (S160-8-8) and the process of subtracting 1 from the value of the round counter (S160-8-) 9) is performed. In the special winning opening closing process (S160-8-8), a special winning opening closing command is set in the output buffer. Subsequently, it is determined whether or not the round counter is 0 (S160-8-10). If the round counter is not 0, the special electric accessory processing (S160-8) is finished as it is, and the round counter is processed. When the counter is 0, the jackpot end process (S160-8-11) is performed, and then the jackpot end flag is turned ON (S160-8-12), and this special electric accessory process (S160-8) Ends.

  On the other hand, when it is determined in S160-8-2 that the jackpot end flag is ON, that is, when the jackpot end flag is determined, the process of setting the jackpot end flag to OFF (S160-8-13) and the process of turning the jackpot flag off. (S160-8-14) is performed, and then it is determined whether the stop symbol is a probabilistic symbol (an odd number in the present embodiment) (S160-8-15). In the case of the probability variation symbol, the probability variation flag is turned ON (S160-8-16) and the special operation status is set to 1 (S160-8-17), while the probability variation symbol is different from the probability variation symbol.

  In the other processing (S180), various other processing necessary for the game is performed, but description of processing that is not particularly relevant in the present invention is omitted.

  In the winning voltage monitoring process (S190, S190A), a process in the case of abnormality detection is performed. FIG. 25 shows a winning voltage monitoring process (S190) performed in the case of the first reference example in the abnormality detection. In the winning voltage monitoring process (S190), it is confirmed whether or not the CPU of the main control means 200 has received the detected voltage interruption signal from the voltage abnormality detection circuit (detection voltage monitoring means) 203 (S190-1). If not, the winning voltage monitoring process (S190) ends. On the other hand, if the detected voltage interruption signal is received, the fact that the detected voltage interruption signal has been received (that is, abnormality) is indicated by the speaker 38 and A detection signal (L bell) is received when a command for notification by at least one of the display device 10 or the like is set (S190-2) and a winning is detected by the winning opening detection switch (detecting means). ) Is invalidated (S190-3), and then the winning voltage monitoring process (S190) is terminated.

  FIG. 26 shows a winning voltage monitoring process (S190A) performed in the case of the second reference example in the abnormality detection. In the winning voltage monitoring process (S190A), it is confirmed whether the CPU of the main control means 200 has received the detected voltage interruption signal from the voltage abnormality detection circuit (detection voltage monitoring means) 203 (S190A-1), and has not been received. In this case, the winning voltage monitoring process (S190A) ends. On the other hand, if the detected voltage power-off signal is received, it is confirmed whether the power-off signal is received from the power board 250 (S190A-2). If the power-off signal is not received, A command for notifying that the detected voltage power-off signal has been received (that is, an abnormality) is set by at least one of the speaker 38 or the display device 10 (S190A-3), and the winning prize detection switch (detecting means) The winning detection invalidation process (S190A-4) for invalidating the detection signal (L level) received when a winning is detected is performed, and then the winning voltage monitoring process (S190A) ends. On the other hand, if it is determined in S190A-2 that a power-off signal has been received, the detection signal (L level) received when a winning is detected by the winning opening detection switch (detecting means) is invalidated. Without performing the process (S190A-4), that is, the received detection signal (L level) is validated, and the winning voltage monitoring process (S190A) is terminated.

  Although the winning voltage monitoring process in the third reference example in the abnormality detection is not shown, it is first confirmed whether or not a power-off signal is received, and if it is received, the voltage abnormality detection circuit (detection voltage) is detected. Monitoring means) 203 so as not to permit the output of the detection voltage power interruption signal from 203, while when the power supply interruption signal has not been received, the detected voltage power interruption from said voltage abnormality detection circuit (detection voltage monitoring means) 203 Allow signal output. Next, it is confirmed whether the detected voltage power interruption signal has been received. If it has been received, the notification command is set, and then the winning detection invalidation process is performed.

  In addition, the winning voltage monitoring process in the case of the embodiment in the abnormality detection is not shown, but it is confirmed whether the detection voltage interruption signal is received from the voltage abnormality detection circuit (detection voltage monitoring means) 203 and is received. In this case, DC12Vs (second voltage) supplied by the sub power supply board (sub power generation means) 251 from the DC12Va supplied by the power supply board 250 to the monitoring circuit (sub detection power means) 205. The notification command is set by switching to the value) and supplying it to the various winning opening detection switches (detecting means).

  In the power-off monitoring process (S200), as shown in FIG. 27, it is determined whether a power-off signal has been input (S200-1). If not input, the power-off monitoring process (S200) ends. On the other hand, when the power-off signal is input, the current data (state) is stored in the RAM of the main control board 200 (S200-2), and then the power-off flag is turned on (S200-3). Thereafter, loop processing is performed.

  Thus, the gaming machine according to the present embodiment generates DC34V (first voltage value) from the AC24V supplied to the gaming machine from the outside by the power supply board (power generation means), and the power supply board (power generation means). Are provided with second voltage converters A and B and a third voltage converter. The second voltage converter B generates DC 12 Vb used as a power source for at least electric decoration (decorative lamp etc.) from the DC 34 V, and the second voltage The converter A generates at least DC 12Va used as a power source for a winning opening detection switch (detection means) from the DC 34V, while the third voltage converter at least from the DC 34V at least a main control board (control means), a sub control board, etc. DC5V used for the power supply for the control board is generated, and the voltage drop of the DC34V (first voltage value) is monitored by the power supply monitoring means DC34V (first voltage value) so as to output from the power monitoring unit the power disconnection signal when it becomes less than a predetermined voltage value to the main control board CPU (control means) Te.

  On the other hand, in the conventional gaming machine, the power source of the gaming machine is monitored with respect to DC12V, and when the DC12V becomes a predetermined voltage value or less, a power-off signal is output. When power is monitored with DC12V, one of DC12Va and DC12Vb supplies power to the prize opening detection switch and the like, so that the output voltage is not lowered until the reset signal is input when the power is cut off. Since it is necessary to keep it stable, power supply monitoring is performed at DC 12 Vb. However, DC12Vb is supplied to electrical decorations and display devices, and depending on the state of the gaming machine, the output may not be stable, and there is a risk of frequent power interruptions. Therefore, in the gaming machine of this embodiment, stable power supply monitoring can be performed by performing power supply monitoring on the original DC34V (first voltage value) generating DC12V (second voltage value). Yes.

  Further, since the entrance detection switch (detection means) outputs a winning signal (detection signal) when the signal level changes from H → L, a specific frequency is generated when power is monitored at DC34V. By reducing the operation of only the DC12V converter (second voltage converters A and B) using a device or the like, it becomes possible to detect a prize by changing the signal level from H to L even though no prize has actually been won. End up. Therefore, in this embodiment, in order to prevent such injustice, when DC12Va (second voltage value) supplied to the entrance detection switch (detection means) is monitored and DC12Va becomes equal to or lower than a predetermined voltage value. A detection voltage interruption signal is output.

  In this embodiment, DC34V (first voltage value) is generated from the AC24V supplied to the gaming machine from the outside by the power supply board (power generation means), and the second voltage converter is applied to the power supply board (power generation means). A and B are provided, and the second voltage converter B generates DC 12 Vb used as a power source for at least an electric decoration (decorative lamp or the like) from the DC 34 V, while the second voltage converter A receives at least a prize opening from the DC 34 V. DC12Va used for the power supply for the detection switch (detection means) is generated, the voltage drop of the DC34V (first voltage value) is monitored by the power supply monitoring means, and the DC34V (first voltage value) becomes below a predetermined voltage value. In this case, a power-off signal is output from the power monitoring means to the CPU (control means) of the main control board, and the power is shut off by the reset output means. The reset signal is output to the CPU (control means) of the main control board with a predetermined time delay from the output of the signal, and the voltage of DC12Va generated by the second voltage converter A is output from the output of the power-off signal to the output of the reset signal. A voltage maintaining means for maintaining the supply without decreasing is provided.

  In this embodiment, as described above, when the power supply is monitored with DC12Vb as described above, it becomes unstable depending on the state of the gaming machine (usage of lighting (number of lighting, etc.)), and the power supply is frequently cut off. Therefore, stable power supply monitoring is possible by avoiding the possibility of power failure, and DC12Va is output from the output of the power-off signal to the output of the reset signal without reducing the voltage. Thus, it is possible to operate stably until a winning opening switch (detection means) or the like is reset, and it is possible to prevent malfunction such as erroneous winning due to malfunction.

  In addition, this invention is not limited to the said Example. For example, in the embodiment, the second voltage (DC12V) and the third voltage (DC5V) are generated from the first voltage value (DC34V), but the second voltage (DC12V) from AC24V supplied to the gaming machine from the outside A third voltage (DC5V) may be generated. Further, other modifications can be made without departing from the spirit of the present invention.
