  As shown in FIG. 16, the pachinko gaming machine according to the embodiment has five game states: a normal game state, a jackpot game state, a time-saving game state, a probability variation game state, and a latent probability game state. In the normal gaming state, the special symbol winning probability (probability of winning the jackpot lottery) is 1/300, the normal symbol winning probability (probability of winning the normal symbol lottery) is 1/11, the normal symbol variation time is 4.0 seconds, The operation pattern of the electric Chu 50 is set to open once for 0.15 seconds. In the short-time gaming state, the special symbol winning probability is 1/300, the normal symbol winning probability is 11/11, the normal symbol variation time is 1.5 seconds, and the operation pattern of the electric Chu 50 is 1.80 seconds. The probable game state has a special symbol winning probability of 1/30, a normal symbol winning probability of 11/11, a normal symbol fluctuation time of 1.5 seconds, and an operation pattern of the electric Chu 50 of 1.80 seconds. In the latent game state, the special symbol winning probability is 1/30, the normal symbol winning probability is 1/11, the normal symbol variation time is 4.0 seconds, and the operation pattern of the electric Chu 50 is 0.15 seconds. In the short-time gaming state and the probability variation gaming state, the so-called electric support (electric chew support) in which the normal symbol winning probability is high, the normal symbol variation time is short, the opening time of the electric chew 50 is long, and the electric chew 50 is easy to open. ) Yes. On the other hand, the normal gaming state and the latent gaming state are states without electric support, and the latent gaming state has a higher probability of winning the special symbol than the normal gaming state, but is it a latent gaming state or a normal gaming state? Is hard to understand. The jackpot game state is a state in which a jackpot game is executed that opens and closes the big prize opening 71 a predetermined number of times, the normal symbol winning probability is 1/11, the normal symbol variation time is 4.0 seconds, and the operation pattern of the electric Chu 50 is 0.15. The opening of the second is one time. Also, in the big hit gaming state, even if a game ball wins the first starting port 51a or the second starting port 51b, the big hit lottery is not executed, and if the holding number is less than the upper limit, the winning is held, and then Since the jackpot lottery is executed for a winning placed in the gaming state (short-time gaming state, probability variation gaming state, or latent probability gaming state) transitioned to, the special symbol winning probability is not displayed in FIG.

  The pachinko gaming machine according to the embodiment is in a normal gaming state at the start of the game, and transitions to a gaming state corresponding to the type of jackpot through the jackpot gaming state. The types of jackpots include 15R (round) normal jackpots, 15R probability variation jackpots, 2R latent probability (latency probability variation) jackpots, and 2R sudden hit jackpots. In addition to these jackpots, there is a jackpot. The round means the opening period of the big winning opening 71. If the 15R probability variation jackpot, after performing the jackpot game that opens the big winning opening 71 15 times, transition to the probability variation gaming state, if 15R normal jackpot, After performing a jackpot game that opens the big prize opening 71 15 times, transitions to the short-time gaming state, and if 2R sudden hit big hit, after performing the jackpot game that opens the big prize opening 71 twice in a very short time, the probability change If it changes to a gaming state and is 2R latent probability big hit, after performing the big hit game which opens the big winning opening 71 twice for a very short time, it changes to the latent gaming state. 15R probability variable jackpot and 15R normal jackpot are long hits, 2R latent chance big hits and 2R sudden hit big hits are short hits. In long hits, a player can win a large number of prize balls, but in short hits, he wins a big prize 71 Since there are almost no winnings, the player can hardly get a prize ball. In addition, if it is a small hit, a small hit game is performed in which the big winning opening 71 is opened twice in a very short time, but the game state does not change. As with short wins, players can hardly win prize balls. Hereinafter, the jackpot game and the jackpot game are referred to as hit games. In addition, when the symbol variation effect is performed 100 times without generating a big hit on the way in the short-time gaming state, the game state transitions to the normal gaming state. Although not shown in the figure, when the symbol variation effect is performed 10,000 times without generating a big hit in the middle in the probability variation gaming state or the latent probability gaming state, the game state transitions to the normal gaming state.

  Next, the operation of the main control unit 30 will be described. As shown in FIG. 4, the main control unit 30 repeats the timer interrupt process every short time, for example, 4 msec. However, when a latch signal is input to the first latch terminal or the second latch terminal (the latch signal is ON). In the case of (), the latch interrupt process is performed in preference to the timer interrupt process. That is, after interrupting the timer interrupt process and performing the latch interrupt process, the process returns to the timer interrupt process. Details will be described below.

  [Latch Interrupt Processing] As shown in FIG. 5, in the latch interrupt processing, the main control unit 30 latches (holds) the numerical value generated at that time in the counter 39 by the latch register 40 (S1201). Based on the latch signal, the start winning prize is determined. Specifically, the main control unit 30 reads the latch signals of the first start port SW54a and the second start port SW54b twice at a predetermined interval (S1202), and the latch signal from the first start port SW54a is both ON. If there is, the winning confirmation to the first starting opening 51a is confirmed, and if it is not even once, it is determined that the winning confirmation to the first starting opening 51a is not confirmed (S1203), and the latch signal from the second starting opening SW54b is both ON. If there is, it is determined that the winning is confirmed at the second starting opening 51b, and if it is not ON even once, the winning is confirmed at the second starting opening 51b (S1210). The reason for reading the signal twice and confirming the winning (ie, determining that the winning has been surely made) is for noise countermeasures.

  If it is determined in step S1203 that the winning for the first starting port 51a is confirmed, the process proceeds to step S1204, and whether or not the starting port SW signal is input from the first starting port SW54a (ON). Determine. The latch signal and the start port SW signal are input to the main control unit 30 later than the former because the latter passes through the input port 35, but the interval when the latch signal is read twice. Is set to be equal to or longer than the time difference between the latch signal and the start port SW signal, the start port SW signal should be input when the start winning is determined by the latch signal. The deviation time between the latch signal and the start port SW signal in a normal state can be estimated by the configuration of the pachinko gaming machine. When the start port SW signal is input, the main control unit 30 proceeds to step S1206. When the start port SW signal is not input, the main control unit 30 performs predetermined error processing (S1205), and then proceeds to step S1206. In step S1206, the main control unit 30 determines whether or not the value U1 of the first start port hold counter that counts the number of jackpot random numbers stored in the first hold storage unit 27a is less than the upper limit value of 4, If it is not less than 4, the latch interrupt process is terminated. If it is less than 4, 1 is added to U1 (S1207), and the jackpot random number held in the latch register 40 is obtained from the latch register 40 at that time. While storing in the 1st pending | holding memory | storage part 27a, a jackpot symbol random number etc. are acquired and memorize | stored in a predetermined storage area (S1208), a 1st pending | holding number increase command is set (S1209), and a latch interruption process is complete | finished.

  On the other hand, if the main control unit 30 determines in step S1210 that the winning to the second starting port 51b is confirmed, the main control unit 30 proceeds to step S1211. If it is determined that the winning is not confirmed, the main control unit 30 ends the latch interruption process. In step S1211, it is determined whether or not the start port SW signal is input from the second start port SW54b. If it is input, the process proceeds to step S1213. If not, predetermined error processing is performed. After going (S1212), the process proceeds to step S1213. In step S1213, the main control unit determines whether or not the value U2 of the second start port hold counter that counts the number of jackpot random numbers stored in the second hold storage unit 27b is less than the upper limit value of 4; If it is not less, the latch interrupt processing is terminated. If it is less than 4, 1 is added to U2 (S1214), and the jackpot random number held in the latch register 40 at that time is obtained from the latch register 40 to 2 In addition to storing in the reserved storage unit 27b, the jackpot symbol random number and the like are acquired and stored in a predetermined storage area (S1215), the second increase in the number of reserved numbers is set (S1216), and the latch interrupt process is terminated.

  In the present embodiment, the error process is a notification process to the outside, and the main control unit 30 sends predetermined information indicating an error to an external device (for example, via an output port and an interface (not shown) provided on the main control board 20). The processing is to output to a lamp device connected to the pachinko gaming machine and provided above the pachinko gaming machine, or a hall-side computer connected to the pachinko gaming machine via the lamp device. If an external device receives predetermined information indicating an error, it is possible that the person on the hall side has been improper if it is notified by lighting the lamp or displaying it on the screen. For example, when such notification is made a plurality of times, there is a high possibility of fraud, so that the operation of the pachinko gaming machine is stopped and the inside can be investigated.

  [Timer Interrupt Processing] As shown in FIG. 6, in the timer interrupt processing, the main control unit 30 performs, in addition to a gate SW processing (S101), which will be described later, a big winning opening SW processing (S102) and a normal winning opening SW processing. (S103) is performed. In the big winning opening SW process, if the big winning opening SW 74 is ON, it is determined whether or not a winning game (a winning game flag described later is ON) is determined. In this process, 1 is added to C and 1 is added to the value of the big prize counter. The normal winning opening SW process is a process of adding 1 to the value of the normal winning opening counter if the normal winning opening SW 91 is ON. Subsequently, the main control unit 30 performs a special symbol process (S104), a normal symbol process (S105), a big prize opening process (S106), and an electric chew process (S107) which will be described later. Then, the main control unit 30 sets a command for paying out the number of prize balls according to the value of the big prize mouth counter and the number of prize balls according to the value of the normal prize mouth counter, A prize ball process (S108) for clearing the counter to zero is performed, and an output process (S109) for outputting the command set in each of the above processes to the payout control board 21 and the effect control board 22 is performed.

  [Gate SW Processing] As shown in FIG. 7, in the gate SW processing, the main control unit 30 determines whether or not the gate SW 81 is turned on (S301). For example, it is determined whether or not the value G of the gate hold counter is less than the upper limit of 4 (S302). If it is not less than 4, the gate SW process is terminated. If it is less than 4, 1 is added to G (S303), a winning random number is acquired and stored in a predetermined storage area (S304), and the gate SW process is terminated. .

  [Special Symbol Processing] As shown in FIG. 8, in the special symbol processing, the main control unit 30 makes a winning game flag indicating whether or not a winning game is being played (that is, a small winning game flag, a long winning game flag, or a short game flag). It is determined whether or not the winning game flag) is ON (S401). If it is ON, the special symbol variation cannot be started and the process is terminated. If it is not ON, it is determined whether or not the special symbol is changing (S402). ). Then, if it is changing, the process proceeds to step S411. If it is not changing, since the change of the special symbol can be started, it is determined whether or not the value U2 of the second start port holding counter is 1 or more (S403). If U2 is 1 or more, the main control unit 30 uses the jackpot random number stored first in the second reserved storage unit 27b, which is stored first in the jackpot determination process (S407) described later. , 1 is subtracted from U2 (S404). On the other hand, if U2 is not 1 or more, it is determined whether or not the value U1 of the first start port holding counter is 1 or more (S405). If U1 is not 1 or more, the process ends, but U1 is 1 or more. If this is the case, the first jackpot random number stored in the first hold storage unit 27a is used for the jackpot determination process (S407), and 1 is subtracted from U1 (S406).

  The main control unit 30 performs jackpot determination processing described later in step S407, performs variation pattern selection processing for selecting a variation pattern of the special symbol (S408), starts variation of the special symbol (S409), and initiates a variation start command Is set (S410), and the process proceeds to step S411. In step S411, it is determined whether or not the variation time of the special symbol has elapsed, and if it has not elapsed, the special symbol processing is terminated, but if it has elapsed, the variation of the special symbol is stopped and the jackpot determination processing is performed. A special symbol is fixedly displayed with the set symbol (S412), a variable stop command is set (S413), a stop process (S414) described later is performed, and the special symbol process is completed.

  [Big jackpot determination process] As shown in FIG. 9, in the big hit determination process, the main control unit 30, as shown in FIGS. Using the jackpot determination table in which the random number value to be won is stored, it is determined whether or not the jackpot random number stored in the first hold storage unit 27a or the second hold storage unit 27b is a jackpot as described above. Perform (S501). For example, if the current gaming state is a probability variation gaming state and the jackpot random number is “7”, it is a jackpot. If it is a big hit (YES in S502), the big hit symbol random number stored in step S1208 or S1215 indicates which jackpot symbol indicates if it is a big hit based on winning in the first starting port 51a. 17 (c), if it is a big hit based on the winning to the second starting port 51b, it is determined using the big hit symbol determination table shown in FIG. 17 (d) (S503), and the big hit symbol is set (S504). The jackpot design is determined by the jackpot design. For example, if the jackpot is based on a winning at the first start port 51a and the jackpot symbol random number is “200”, the 2R latent probability symbol is set and the 2R latent probability jackpot is reached. As can be seen from the jackpot symbol determination table, the jackpot based on the winning at the second starting port 51b has a higher ratio per long than the jackpot based on the winning at the first starting port 51a. It is easy to win a large number of prize balls. On the other hand, if the jackpot random number is not a jackpot (NO in S502), but if it is a small hit (YES in S505), a small hit symbol is set (S506), if it is not a small hit (NO in S505), a lost symbol is set. (S507). The main control unit 30 deletes the jackpot random number used for the determination from the holding storage unit 27.

  [In-stop processing] As shown in FIG. 10, in the in-stop processing, the main control unit 30 determines whether or not the short-time game flag indicating whether or not the short-time game state is ON (S701). The process proceeds to step S705. If ON, the value J of the hour fluctuation counter that counts the number of times the special symbol is changed in the hourly gaming state is decremented by 1 (S702). If J is 0, the hourly gaming state is terminated. The time-saving game flag is turned off (S703, 704), and the process proceeds to step S705.

  In step S705, the main control unit 30 determines whether or not the probability variation game flag indicating whether or not the probability variation game state or the latent probability game flag indicating whether or not the latent probability game state is ON. If this is the case, the process proceeds to step S709. If either is ON, the value X of the high probability variation counter that counts the number of variations of the special symbol in the probability variation gaming state or the latent probability gaming state is decremented by 1 (S706). If it is 0, in order to end the probability variation gaming state or the latent certainty gaming state, the probability variation gaming flag or the latent certainty gaming flag that was ON is turned off (S712, 713), and the process proceeds to step S709.

  In step S709, it is determined whether or not the jackpot (that is, whether or not the stopped special symbol is a jackpot symbol) (S709). If it is not a long hit, the short hit game flag is turned on (S710, 711). Then, the time variation counter value J and the high probability variation counter value X are set to 0 (S713), the time variation game flag, the probability variation game flag, and the latent probability game flag are turned off (S714), and the opening starts ( S717), an opening command is set (S718), and the stop process is finished.

  On the other hand, if it is not a big hit (NO in S709), the main control unit 30 determines whether or not it is a small hit (S715). The winning game flag is turned ON (S716), the opening is started (S717), the opening command is set (S718), and the stop process is finished.

  [Normal Symbol Processing] As shown in FIG. 11, in the normal symbol processing, the main control unit 30 determines whether or not an auxiliary game flag indicating whether or not an auxiliary game is in progress (S801). If the normal symbol processing is finished, and if it is not ON, it is determined whether or not the normal symbol is changing (S802). If it is changing, the process proceeds to step S809. If it is not changing, it is determined whether the value G of the gate hold counter is 1 or more (S803). If G is not 1 or more, normal symbol processing is performed. When G is 1 or more, 1 is subtracted from G (S804), it is determined whether or not the winning random number stored in step S304 is hit (S805), and a stop symbol is selected (S806). ). Then, the variation time corresponding to the gaming state (in this embodiment, 4.0 seconds for the normal gaming state or the latent probability gaming state, 1.5 seconds for the short-time gaming state or the probability variation gaming state) is selected (S807). The change of the symbol is started (S808), and the process proceeds to step S809.

  In step S809, the main control unit 30 determines whether or not the variation time has elapsed. If the variation time has not elapsed, the main control unit 30 finishes the normal symbol processing. Is displayed (S810). If the stop symbol is a symbol indicating winning (YES in S811), the auxiliary game flag is turned ON (S812). If the symbol indicating a loss is determined (NO in S811), the normal symbol processing is terminated.

  [Big winning mouth process] As shown in FIG. 12, in the big winning hole process, the main control unit 30 first determines whether or not the winning game flag is ON (S901). If it is ON, it is determined whether or not opening is in progress (S902). The opening is a period from the start of the jackpot game to the start of the first round. If it is determined that the opening is in progress, the main control unit 30 determines whether or not the opening time has elapsed (S903). A maximum R number (round number) and an operation pattern are set according to the type (S904). Here, if it is per long, the number of R is 15, and the operating pattern during 1 round is 29.5 seconds, and if it is short, the number of R is 2, and the operating pattern during 1 round is 0.8 seconds. In the case of a small hit, the R number is 1, and the operation pattern in one round is 0.8 seconds and the opening is 2 times. Then, the value C of the winning number counter is cleared to zero (S905), and 1 is added to the value R of the round counter (S906). If it is once open, if it is a short hit, an operation is started once for 0.8 seconds, and if it is a small hit, it is started twice for 0.8 seconds (S907).

  Next, the main control unit 30 determines whether or not the operation time of the big winning opening 71 (time required for execution of the operation pattern of one round) has passed (S908). When the operation is finished (S910) and the time has not elapsed, it is determined whether or not the value C of the winning number counter is a specified number (9 in this case) (S909). After the mouth processing is finished, the operation of the special winning opening 71 is finished if the number is the prescribed number (S910). In the case of short wins and small wins, since the opening time of the big winning opening 71 is extremely short, a prescribed number of winnings are not won in the big winning opening 71.

  Then, the main control unit 30 determines whether or not the value R of the round counter is the maximum number of Rs (S911). If it is not the maximum number of Rs, the big winning opening process is finished. Is started (S912), an ending command is set (S913), and the value R of the round counter is cleared to zero (S914). Ending refers to the period from the end of the final round to the end of the jackpot game. Next, the main control unit 30 determines whether or not the ending time has elapsed (S917), and if it has not elapsed, finishes the big prize opening process, and if it has elapsed, performs a game state setting process to be described later. (S918), the winning game flag is turned OFF.

  On the other hand, when the main control unit 30 determines in step S902 that the opening is not in progress, the main control unit 30 determines whether or not the special winning opening 71 is in the ending (S915). If the ending is in progress, the process proceeds to step S917. If it is not ending, it is determined whether or not the special winning opening is in operation (S916). If it is not in operation, the process proceeds to step S905. If it is in operation, the process proceeds to step S908.

  [Game State Setting Process] As shown in FIG. 13, in the game state setting process, if the winning game that has just ended is a small hit (YES in S1001), the game state is not changed, so the game is not changed. If the state setting process is completed and the game is normally a big hit (YES in S1002), the time-short game flag is turned ON (S1003) and the value J of the time-variation counter is set to 100 (S1004). If it is a probable big hit (YES in S1005), the game state is changed to the probable gaming state, so the probable gaming flag is turned on (S1006). In order to make a transition to the probable gaming state, the latent promising game flag is turned on (S1007), and the value X of the high probability variation counter is set to 10000 (S1008).

  [Electric Chu Process] As shown in FIG. 14, in the electric Chu process, the main control unit 30 determines whether or not the auxiliary game flag is ON (S1101). On the other hand, if it is determined to be ON, it is determined whether or not the electric chew 50 is in operation (S1102). If it is in operation, the process proceeds to step S1105. The operation pattern (in this embodiment, if the normal game state or the latent probable game state, release 0.15 seconds once, if it is the short-time game state or the probable game state, 3 times 1.80 seconds release) (S1103), the operation according to the operation pattern is started (S1104), and the process proceeds to step S1105. In step S1105, the main control unit 30 determines whether or not the operating time has elapsed (S1105). If it has not elapsed, the electric chew process is terminated, and if it has elapsed, the auxiliary game flag is turned OFF (S1106). ), The electric chew process is finished.

  Referring to FIG. 4, the main control unit 30 repeats timer interrupt processing including special symbol processing every predetermined time. However, when the latch signal is turned ON, the timer interrupt processing is interrupted and the latch interrupt processing is performed. Is called. In the latch interrupt process, the main control unit 30 holds the jackpot random number in the latch register 40, reads the latch signal twice as indicated by the dotted arrow in FIG. 4, and determines whether or not the start prize is confirmed. If it is determined that the start prize is confirmed for the first start port 51a, it is determined whether or not the start port SW signal from the first start port SW54a is ON. If not, error processing is performed. Does not perform error handling. If the number of jackpot random numbers stored in the first hold storage unit 27a is not the upper limit, the jackpot random number held in the latch register 40 is stored in the first hold storage unit 27a. The same applies to the case where it is determined that the starting prize has been confirmed for the second starting port 51b. Then, the main control unit 30 finishes the latch interrupt process and returns to the timer interrupt process. In the special symbol process during the timer interrupt process, the main control unit 30 stores the jackpot determination process, that is, if the jackpot random number is stored in the first reserved storage section 27a or the second reserved storage section 27b. Judgment is made whether or not the big hit using the big hit random number.

  The pachinko gaming machine according to the present embodiment determines whether or not the start port switch signal is inputted when the winning to the start port is confirmed based on the latch signal in the latch interrupt process. In the pachinko gaming machine in which the winning at the starting port is confirmed based on the latch signal, the numerical value acquired from the numerical value generating means is stored in the storage area for the big hit determination, and the big hit determination is performed. It is possible to detect fraud that makes a jackpot determination by inputting only a latch signal.

  Note that latch interrupt processing may be performed as shown in FIG. Hereinafter, a description will be given based on FIG. The main control unit 30 latches the numerical value generated at that time in the counter 39 by the latch register 40 (S1301). Then, the main control unit 30 sets the latch signals of the first start port SW54a and the second start port SW54b to a predetermined interval (the interval at this time may be shorter than the normal deviation time between the latch signal and the start port SW signal). .) Is read twice (S1302), and if the latch signal from the first start port SW54a is both ON, the winning confirmation to the first start port 51a is confirmed, and if not once, the first start port 51a is determined. If the latch signal from the second starting port SW54b is both ON, the winning determination to the second starting port 51b is confirmed, and if it is not once, the second starting port 51b is determined. It is determined that the winning is not confirmed (S1312).

  If it is determined in step S1303 that the first start opening 51a has been confirmed, the process proceeds to step S1304, and measurement of an elapsed time Δt from the confirmed winning is started (S1304). Although a configuration for measuring Δt is not shown, for example, a configuration in which a counter for Δt measurement is provided and a reference clock signal from the oscillation circuit 36 is input to the counter and counted can be considered. Next, the main control unit 30 determines whether Δt is less than a predetermined time (S1305). This predetermined time is a time that is apparently abnormal when the input of the start port SW signal is further delayed after the winning is confirmed, and the interval when the latch signal is read twice is normal between the latch signal and the start port SW signal. If it is shorter than the gap time, the start port SW signal may not be input yet at the time of winning, so that it can be checked whether the start port SW signal is input within a normal time. is there. For example, the predetermined time can be a time obtained by subtracting an interval time when the latch signal is read twice from a normal deviation time between the latch signal and the start port SW signal. If Δt is less than the predetermined time, the main control unit 30 determines whether or not a start port SW signal is input from the first start port SW 54a (S1306), and if it is input, the process proceeds to step S1308. If not, the process returns to step S1305. If Δt is not less than the predetermined time, predetermined error processing is performed (S1307), and the process proceeds to step S1308. In step S1308, the main control unit 30 determines whether or not the value U1 of the first start port hold counter is less than the upper limit value of 4, and if not less than 4, terminates the latch interrupt process and if less than 4, Adds 1 to U1 (S1309), acquires the jackpot random number held in the latch register 40 at that time from the latch register 40 and stores it in the first holding storage unit 27a, and also acquires the jackpot symbol random number and the like Then, it is stored in a predetermined storage area (S1310), the first pending number increase command is set (S1311), and the latch interrupt process is terminated.

  On the other hand, the main control unit 30 proceeds to step S1313 when it is determined in step S1312 that the winning to the second starting port 51b is confirmed, and ends the latch interruption process when it is determined that the winning is not confirmed. In steps S1313 to 1315, as in steps S1304 to 1306, it is determined whether or not the start port SW signal is input from the second start port SW54b within a predetermined time. The process proceeds to S1317, and if it is not input within a predetermined time, a predetermined error process is performed (S1316), and then the process proceeds to Step S1317. In step S1317, the main control unit determines whether or not the value U2 of the second start port hold counter is less than the upper limit value of 4, and if it is not less than 4, finishes the latch interrupt process and if less than 4, 1 is added to U2 (S1318), and the jackpot random number held in the latch register 40 at that time is acquired from the latch register 40 and stored in the second holding storage unit 27b, and the jackpot symbol random number is acquired. And store it in the predetermined storage area (S1319), set the second pending number increase command (S1320), and end the latch interrupt process.

  In the latch process shown in FIG. 15, when a winning at the starting port is confirmed, it is determined whether or not the starting port switch signal is input within a predetermined time after the winning is confirmed. In a pachinko gaming machine in which a winning at the starting port is determined based on the latch signal, the numerical value obtained from the numerical value generating means is stored in the jackpot determination storage area, and the jackpot determination is performed. It is possible to detect fraud that makes a big hit determination by inputting only a signal. In addition, when a latch signal is read twice at intervals shorter than the deviation time from the start port SW signal and a winning is confirmed, or when a winning is confirmed without reading the latch signal twice, a winning by a latch signal is performed. The present invention is also applicable to the case where the start port SW signal may not be input at the time of confirmation.

  If it is known from the first start port SW54a or the second start port SW54b that the latch signal that triggered the start of the latch interrupt process is within the latch interrupt process, Then, instead of reading the latch signal twice, it is also possible to read the latch signal of the one that triggered it once and confirm the winning, or if you do not take noise countermeasures in the latch interrupt process, In the interrupt process, the winning may be confirmed without reading the latch signal.

  In the above embodiment, the first storage unit is the latch register 40, but the first storage unit may be a storage area in the RAM 33 (however, an area different from the reserved storage unit 27). That is, in the latch interrupt process, the numerical value generated by the numerical value generating means 37 is temporarily held in the latch register 40 and further stored in the first storage unit in the RAM 33 from the latch register 40, thereby confirming the start winning prize. Thereafter, numerical values may be stored from the first storage unit to the hold storage unit 27 which is the second storage unit.

  In the above embodiment, the oscillation circuit 36 is not included in the numerical value generation unit 37. However, the numerical value generation unit 37 may include the oscillation circuit 36. In such a case, the main control unit 30 also includes the oscillation circuit 36, and the main control unit 30 is constituted by the one-chip microcomputer and the oscillation circuit 36 described above. Furthermore, in the above embodiment, the main control unit 30 is a one-chip microcomputer provided with the numerical value generation means 37. However, the main control unit 30 is connected to a one-chip microcomputer that does not include the numerical value generation means 37 and the one-chip microcomputer. The numerical value generating means 37 such as a generated random number generator (external random number generator) can also be used.

  Further, the numerical value generated by the numerical value generating unit 37 may be random or sequential.

  When a numerical value of a plurality of bits (for example, 8 bits) is input from the latch register 40 to the CPU 31 via a signal line that transmits the value of each bit, the order of the bits in the latch register 40 is changed on the CPU 31 side. By connecting each signal line, the numerical value held in the latch register 40 may be randomized and input to the CPU 31, and the CPU 31 may store the randomized numerical value in the holding storage unit 27. That is, the numerical value stored in the first storage unit is not directly stored in the hold storage unit 27 as the second storage unit, but the numerical value stored in the first storage unit. The numerical value generated from the above may be stored in the second storage unit.

  Further, as described above, each signal line is connected so that the order of each bit in the latch register 40 is changed on the CPU 31 side, and the first storage unit is held in the latch register 40 as a storage area in the RAM 33. When the numerical value is randomized and input to the CPU 31 and the CPU 31 stores the randomized numerical value in the first storage unit, the value of each bit in the latch register 40 is included up to each signal line that transmits to the CPU 31. Thus, it can be said to be the numerical value generation means 37.

  Further, in the above embodiment, after error processing is performed, the processing is returned to the original flow (flow when error processing is not performed). This is because if the pachinko machine operation is stopped every time error processing is performed, even if error processing is performed due to noise, the operation of the pachinko machine may be stopped and the interest of the game may be impaired. Of course, the pachinko gaming machine may be configured to stop operating after error processing, or the pachinko gaming machine may be stopped during error processing.
