  As shown in FIG. 19, 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 with respect to a winning placed in the gaming state (time-short gaming state, probability-changing 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.

  [Timer Interrupt Processing] As shown in FIG. 5, in the timer interrupt processing, the main control unit 30 performs a special winning opening SW processing (in addition to a start opening SW processing (S101) and a gate SW processing (S102) described later) S103) and a normal winning opening SW process (S104). 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 (S105), a normal symbol process (S106), a big prize opening process (S107), and an electric chew process (S108) 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 (S109) for clearing the counter to zero is performed, and an output process (S110) 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.

  [Starting Port SW Process] As shown in FIG. 6, in the starting port SW process, the main control unit 30 determines the starting prize based on the starting port SW signal input via the input port 35. Specifically, the main control unit 30 reads the start port SW signal from the first start port SW 54a twice at a predetermined interval, and determines that the winning is confirmed to the first start port 51a if both are ON (S201). If YES, it is determined that the winning is not confirmed (NO in S201). The reason why the signal is read twice in this manner and the winning is confirmed (that is, it is determined that the winning is surely made) is for noise countermeasures. Then, if the winning is not confirmed, the process proceeds to step S206, but if the winning is confirmed, the process proceeds to step S202, and the first start port holding counter counts the number of jackpot random numbers stored in the first holding storage unit 27a. It is determined whether or not the value U1 is less than the upper limit of 4. If it is not less than 4, the process proceeds to step S206. If it is less than 4, 1 is added to U1 (S203), and then held in the latch register 40. The jackpot random number is acquired from the latch register 40 and stored in the first hold storage unit 27a, the jackpot symbol random number is acquired and stored in a predetermined storage area (S204), and the first hold number increase command is set. Then (S205), the process proceeds to step S206.

  In step S206, the main control unit 30 determines whether or not the start winning is determined based on the starting port SW signal from the second starting port SW54b as in the case of the first starting port SW54a, and determines that the winning is determined. If so, the process proceeds to step S207, and if it is determined that the winning is not confirmed, the start port SW process is terminated. In step S207, it is determined 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, and if not less than 4, the process is started. When the mouth SW processing is finished and the number is less than 4, 1 is added to U2 (S208), and the jackpot random number held in the latch register 40 at that time is acquired from the latch register 40 to obtain the second hold storage unit 27b. Are stored in a predetermined storage area (S209), a second reserved number increase command is set (S210), and the start port SW process is terminated. Note that the length of the start port SW signal (the length of the ON period) generated when a game ball wins the first start port 51a or the second start port 51b is the start port during any timer interruption process. The length of the timer interruption process is equal to or longer than one time so that the start winning is always confirmed in the SW process. Also, the level of the start port SW signal read in the previous start port SW process and the start port SW signal read in the current start port SW process are set so that the start winning is not confirmed multiple times with the same start port SW signal. Only when a rise from OFF to ON is detected by comparing with the level, the start prize is confirmed.

  [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, 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 jackpot (YES in S502), the jackpot symbol random number stored in step S204 or S209 indicates which jackpot symbol indicates if it is a jackpot based on winning in the first starting port 51a. 20 (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. 20 (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 time-short gaming state or the probability variation gaming state) is selected (S807) The normal symbol change 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 not in operation, the process proceeds to step S905, and if 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.

  [Latch Interrupt Processing] In the latch interrupt processing, as shown in FIG. 15, the main control unit 30 latches (holds) the numerical value generated at that time in the counter 39 by the latch register 40 (S1201). Then, measurement of the shift time Δt between the latch signal and the start port SW signal is started (S1202). Although a configuration for measuring Δt is not illustrated, for example, a configuration in which a counter for measuring a deviation time 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 or not the corresponding start port SW signal is ON, that is, the latch signal that triggered the current latch interrupt processing is input to the first latch terminal. If so, whether or not the start port SW signal from the first start port SW54a is ON, and if it is input to the second latch terminal, whether or not the start port SW signal from the second start port SW54b is ON. Is determined (S1203). If the corresponding start port SW signal is not ON, the main control unit 30 returns to the determination in step S1203. That is, the determination in step S1203 is repeated while the measurement of Δt is continued until the corresponding start port SW signal is turned ON. On the other hand, if the corresponding start port SW signal is ON, the measurement of Δt is terminated (S1204), and it is determined whether Δt exceeds a predetermined upper limit time (S1205). In the latch signal and the start port SW signal based on the same signal output from the first start port SW54a or the second start port SW54b, since the start port SW signal passes through the input port 35, it is delayed from the latch signal. Although it will be input to the control unit 30, the degree of deviation between the two can be estimated by the configuration of the pachinko gaming machine. Therefore, the time that is apparently abnormal if the deviation is further exceeded is determined in advance as the upper limit time.

  If Δt does not exceed the predetermined upper limit time (NO in S1205), the main control unit 30 finishes the latch interrupt process and returns to the timer interrupt process. If it exceeds (YES in S1205), the main control unit 30 After performing the error processing (S1206), the latch interrupt processing is finished and the processing returns to the timer interrupt processing. In the present embodiment, the error process is a notification process to the outside. Here, the main control unit 30 sends predetermined information indicating an error to an external device via an output port and an interface (not shown) provided on the main control board 20. The processing is output to a device (for example, a lamp device connected to a pachinko gaming machine and provided above the pachinko gaming machine, or a hall computer connected to the pachinko gaming machine via the lamp device).

  Referring to FIG. 4, the main control unit 30 repeats the timer interrupt process including the start port SW process, but when the latch signal is turned ON, the timer interrupt process is interrupted and the latch interrupt process is performed. In the latch interrupt process, the main control unit 30 holds the big hit random number in the latch register 40, and measures the deviation time Δt until the ON of the start port SW signal is detected. If Δt does not exceed the predetermined upper limit time, the latch interrupt process is terminated and the process returns to the timer interrupt process. In the start port SW process during the timer interrupt process, the main control unit 30 reads the start port SW signal twice, and if both are ON, determines the start winning (switch confirmation) and holds it in the latch register 40 The stored jackpot random number is stored in the holding storage unit 27. In the jackpot determination process (not shown in FIG. 4) during the timer interrupt process, the main control unit 30 determines whether or not it is a jackpot using the jackpot random number stored in the hold storage unit 27. On the other hand, if the main control unit 30 determines that Δt exceeds a predetermined upper limit time in the latch interrupt processing, after performing error processing to output predetermined information indicating an error to an external device, Return to timer interrupt processing. 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.

  Since the pachinko gaming machine of this embodiment performs error processing when the time difference between the latch signal and the start port switch signal exceeds a predetermined upper limit time, the latch signal or the start port SW signal may be input illegally. The act can be discovered. That is, when the latch signal and the start port SW signal are illegally inputted, it is difficult to input them taking into account their deviation time, and thus the deviation time may exceed the normal normal range. According to the pachinko gaming machine of this embodiment, it is possible to detect such fraud.

  If the latch interrupt process is executed according to the flow shown in FIG. 15, the error process will not be performed until the corresponding start port SW signal is turned ON even if the deviation time has already exceeded the upper limit time. Therefore, the latch interrupt process may be performed according to the flow shown in FIG. In the flow of FIG. 16, the main control unit 30 holds the numerical value generated at that time in the counter 39 in the latch register 40 (S1301), and starts measuring the shift time Δt between the latch signal and the start port SW signal. (S1302). Next, the main control unit 30 determines whether or not the corresponding start port SW signal is ON (S1303). If it is ON, the measurement of Δt is terminated (S1304), and Δt is a predetermined value. It is determined whether or not the upper limit time has been exceeded (S1305). If it has not exceeded, the latch interrupt process is terminated, and if it exceeds, a predetermined error process is performed (S1306), and the latch interrupt process is terminated. On the other hand, if it is determined in step S1303 that it is not ON, it is determined whether or not Δt at that time exceeds a predetermined upper limit time (S1307). If not exceeded, the process returns to the determination in step S1303. If exceeded, the measurement of Δt is terminated (S1308), a predetermined error process is performed (S1309), and the latch interrupt process is terminated. In this way, when the deviation time exceeds the predetermined upper limit time before the corresponding start port SW signal is turned ON, error processing is performed promptly.

  <Second Embodiment> Next, a pachinko gaming machine according to a second embodiment will be described with a focus on differences from the first embodiment. In addition, about the same component as 1st Embodiment, the same code | symbol is used and the description is abbreviate | omitted suitably.

  As shown in FIG. 17, the pachinko gaming machine of the second embodiment includes delay circuits 41 and 42 as delay means for delaying the input of the start port SW signal to the main control unit 30. The delay circuit 41 is on the path of a signal input from the first start port SW54a to the input port 35, and the signal from the first start port SW54a is input to the input port 35, and the first latch terminal It is provided after the branch point that branches to the one that is input to. The delay circuit 42 is on the path of the signal input from the second start port SW54b to the input port 35, and the signal from the second start port SW54b is input to the input port 35, and the second latch terminal It is provided after the branch point that branches to the one that is input to. That is, the delay circuits 41 and 42 delay the start port SW signal, but do not delay the latch signal. The time for which the input of the start port switch signal is delayed by the delay circuits 41 and 42 (hereinafter referred to as “delay time”) is shorter than the above-described upper limit time of the shift time. The configuration of the main control board 20 of the second embodiment is the same as that of the first embodiment except that the delay circuits 41 and 42 are provided.

  Since the operation of the main control unit 30 in the second embodiment is the same as that of the first embodiment except for the latch interrupt process, the latch interrupt process of the second embodiment will be described below with reference to FIG. The main control unit 30 latches the numerical value generated at that time in the counter 39 by the latch register 40 (S1401). Then, measurement of the deviation time Δt between the latch signal and the start port SW signal is started (S1402). Next, the main control unit 30 determines whether or not the corresponding start port SW signal is ON (S1403). If the corresponding start port SW signal is not ON, the process returns to the determination in step S1403. On the other hand, if the corresponding start port SW signal is ON, measurement of Δt is ended (S1404), and it is determined whether Δt exceeds a predetermined upper limit time or whether Δt is less than a predetermined lower limit time. (S1405). In the latch signal and the start port SW signal based on the same signal output from the first start port SW54a or the second start port SW54b, the start port SW signal is input to the main control unit 30 later than the latch signal as described above. However, in the second embodiment, the start port SW signal is input to the main control unit 30 with a delay of at least the above-described delay time from the latch signal. Therefore, a time equal to or shorter than the delay time is set as the lower limit time. In the present embodiment, the delay time by the delay circuit 41 and the delay time by the delay circuit 42 have the same length, but when they are different, a time shorter than the shorter delay time is set as the lower limit time.

  If Δt does not exceed the predetermined upper limit time and is not less than the predetermined lower limit time (NO in S1405), the main control unit 30 ends the latch interrupt process and returns to the timer interrupt process. If the upper limit time is exceeded or less than the predetermined lower limit time (YES in S1405), a predetermined error process (S1406) is performed, then the latch interrupt process is terminated and the process returns to the timer interrupt process. Thus, if it is determined not only whether the deviation time Δt exceeds the upper limit time but also whether it is less than the lower limit time, the deviation time between the latch signal and the start port SW signal is normal due to fraud. Not only when it becomes larger than the range, but also when it becomes smaller than the normal range, it is possible to discover the illegal input of the latch signal and the start port SW signal.

  Also in the second embodiment, as in FIG. 16, when NO is determined in step S1403, it is determined whether or not Δt exceeds a predetermined upper limit time. If not, step S1403 is determined. However, if it exceeds, error processing may be performed to finish the latch interrupt processing.

  Further, in each of the above embodiments, the start winning is determined by reading the start port SW signal twice in one start port SW process, but the start port is only once in one start port SW process. The SW signal is read, and the start winning is confirmed when the start SW signal is continuously turned ON in a plurality of start port SW processes (that is, in a plurality of timer interrupt processes). May be. In such a case, the length of the start port SW signal needs to be a length over the plurality of timer interruption processes.

  In each of the above embodiments, 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, when a latch signal is input, the numerical value generated by the numerical value generation 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. As a result, in the start port SW process, a numerical value may be stored from the first storage unit to the hold storage unit 27 that 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. Further, in each of the above embodiments, 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 replaced with a one-chip microcomputer that does not include the numerical value generation means 37 and the one-chip microcomputer. It can also be constituted by a numerical value generating means 37 such as a connected random number generator (external random number generator).

  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 that the numerical value generation means 37.

  In each of the above embodiments, after performing error processing, 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.
