The result of the internal lottery performed based on the display is clearly shown. In other words, in this pachinko machine 10, the winning to the upper working port 33 and the winning to the lower working port 34 are not distinguished in the internal lottery, and are performed based on the winning to the upper working port 33 or the lower working port 34. The result of the internal lottery is displayed on the main display unit 43 which is a common display area. When the result of the internal lottery based on the winning to the upper operating port 33 or the lower operating port 34 is a winning result corresponding to the shift to the opening / closing execution mode, a predetermined stop result is displayed on the main display unit 43. After the display and the change display are stopped, the mode shifts to the opening / closing execution mode. In addition, when the probability of winning / failing lottery is high after the opening / closing execution mode and when the probability of winning / losing lottery is low after the opening / closing execution mode, stop when the variable display is ended on the main display unit 43. The result is different.

  By the way, based on the winning of one of the operating ports 33, 34, the display of variation is started on the main display unit 43, a predetermined stop result is displayed, and the variation display is stopped once. It corresponds to. In addition, as a pattern variably displayed on the main display unit 43, a configuration in which a plurality of types of characters are variably displayed, a configuration in which a plurality of types of symbols are variably displayed, a configuration in which a plurality of types of characters are variably displayed, or a plurality A configuration in which the color of the seed is switched and displayed can be considered.

  The accessory display unit 44 displays a variation of the picture triggered by a winning to the through gate 35. As a result of stopping the variation display, the result of the internal lottery performed based on the winning to the through gate 35 is displayed. Explicit by display. If the result of the internal lottery based on the winning to the through gate 35 is a winning result corresponding to the transition to the state where the electric role is opened, a predetermined stop result is displayed on the accessory display unit 44 and displayed in a variable manner. After is stopped, it shifts to the electric utility open state. In the electric combination open state, the electric combination 34a provided in the lower working port 34 is opened in a predetermined manner.

On the other hand, in the middle symbol row Z2, nine types of main symbols “1” to “9” are arranged in ascending numerical order, and then between the main symbol “9” and the main symbol “1”. In addition, a main symbol “4” is additionally arranged, and one sub symbol is arranged between each main symbol. In other words, only the middle symbol row Z2 is composed of 20 symbols by arranging 10 main symbols.

  As shown in FIG. 5B, on the display surface G, three symbols are stopped and displayed for each symbol row, and as a result, a total of nine symbols of 3 × 3 are stopped and displayed. It is like that. On the display surface G, five effective lines, that is, a left line L1, a middle line L2, a right line L3, a right lowering line L4, and a right uppering line L5 are set.

  When a game-turning effect is performed on the display surface G based on winning at the upper operating port 33 or the lower operating port 34, the symbols in the symbol rows Z1 to Z3 are scrolled in a predetermined direction with periodicity. The variable display is started. Then, the display is switched from the variable display to the standby display in the order of the upper symbol row Z1 → the lower symbol row Z3 → the middle symbol row Z2, and finally the game is used in a state where a predetermined symbol is statically displayed in each of the symbol rows Z1 to Z3. The production of is ended.

  In addition, when the same game combination is stopped and displayed on one active line when the game round effect is finished, the variable winning device 32 is opened and closed for a predetermined number of times and a large number of game balls are displayed. It will shift to the opening / closing execution mode that enables acquisition. In this case, in the effect for game times corresponding to the case where the probability of winning / failing lottery becomes high after the opening / closing execution mode, a combination of symbols in which the same odd number is attached to any one of the active lines is formed. . On the other hand, in the effect for game times corresponding to the case where the probability of winning / failing lottery becomes low after the opening / closing execution mode, a combination of symbols in which the same even number is attached to any one of the active lines is formed.

  Further, the variation display mode of the symbol in the symbol display device 41 is not limited to the above, and is arbitrary, such as the number of symbol columns, the direction of symbol variation display in the symbol column, the number of symbols in each symbol column, etc. Can be appropriately changed.

The time required for reading is faster than that of the ROM 103 when compared with the data capacity. The RWM 104 temporarily stores various data and the like when executing the control program stored in the ROM 103.

  In addition to the above elements, the MPU 102 or the main control board 101 is provided with an interrupt circuit, a timer circuit, a data input / output circuit, and the like. Note that it is not essential that the ROM 103 and the RWM 104 are made into one chip with respect to the MPU 102, and each may be made into a chip individually.

  The MPU 102 is provided with an input / output port. On the input side of the MPU 102, a power failure monitoring board 105, a payout control device 97, various winning detection sensors 106a to 106h, a magnet detection sensor 109, and the like are connected.

  A power supply and launch control device 98 is connected to the power failure monitoring board 105, and power is supplied to the MPU 102 via the power failure monitoring board 105. In addition, based on the detection results of the various winning detection sensors 106a to 106h, the MPU 102 performs a winning determination (a winning determination) for each winning portion. In addition, the MPU 102 executes a lottery lottery based on a winning at the upper operating port 33 or the lower operating port 34 and also executes a support lottery based on a winning at the through gate 35.

  The magnet detection sensor 109 is installed on the back side of the game board 24 around the upper working port 33. As described above, since the upper operating port 33 is a trigger for the internal lottery, an act of inducing the game ball to the upper operating port 33 illegally by bringing a magnet near the upper operating port 33 in front of the window panel 62. is assumed. On the other hand, when the magnet detection sensor 109 is provided, it is possible to detect an unauthorized act using the magnet. The MPU 102 specifies whether or not the illegal act has occurred based on the detection result of the magnet detection sensor 109.

  On the output side of the MPU 102, a power failure monitoring board 105, a payout control device 97, and a sound and light control device 82 are connected.

  For example, a prize ball command is output to the payout control apparatus 97 based on the winning determination result for the above-mentioned winning part. Various commands such as a change command, a type command, a final stop command, an opening command, and an ending command are output to the sound control device 82.

  Further, on the output side of the MPU 102, the variable winning drive unit 107 that opens and closes the opening / closing door 32 b of the variable winning device 32, the accessory driving unit 108 that opens and closes the electric accessory 34 a of the lower working port 34, and the main display unit 43. And an accessory display 44 is connected. The main control board 101 is provided with various driver circuits, and the MPU 102 performs drive control of various drive units through the driver circuits. Moreover, although explanation by illustration is abbreviate | omitted, light emission control of the 1st reservation light emission part 45 and the 2nd reservation light emission part 46 is also performed by MPU102.

  The power failure monitoring board 105 relays between the main control board 101 and the power supply and launch control device 98, and monitors the voltage of 24 VDC which is the maximum voltage output from the power supply and launch control device 98. The payout control device 97 performs payout control of prize balls and rental balls by the payout device 96 based on the prize ball command input from the main control device 81.

  The power source and launch control device 98 is connected to, for example, a commercial power source (external power source) in a game hall or the like. Based on the external power supplied from the commercial power supply, necessary operating power is generated for each of the main control board 101, the payout control device 97, etc., and the generated operating power is supplied through a predetermined power path. To do. The power supply and launch control device 98 is responsible for launch control of the game ball launch mechanism 53 and drives the game ball launch mechanism 53 based on the fact that a predetermined launch operation on the launch handle 54 has been specified.

  The sound light control device 82 controls the display control device 111 and controls the light emitting unit 63 and the speaker unit 64 provided on the front door frame 14 based on various commands input from the main control device 81. is there. The display control device 111 executes display control of the symbol display device 41 based on the command input from the sound light control device 82.

<Electrical configuration for performing various lotteries in the MPU 102>
Next, an electrical configuration for performing various lotteries in the MPU 102 will be described with reference to FIG.

  The MPU 102 uses lots of counter information during the game to perform jackpot occurrence lottery, setting the display of the main display unit 43, setting the symbol display of the symbol display device 41, setting the display of the accessory display unit 44, and the like. Specifically, as shown in FIG. 7, when the jackpot random number counter C1 used for the lottery occurrence lottery, the jackpot type counter C2 used for determining the jackpot type, and the symbol display device 41 are changed. A reach random number counter C3 used for reach generation lottery, a first initial value counter CN1 used for setting an initial value of the big hit random number counter C1, and a second initial value counter CN2 used for setting an initial value of the big hit type counter C2. And a variation type counter CS that determines the display duration in the main display unit 43 and the symbol display device 41. It is set to. Furthermore, an electric random number counter C4 used for the lottery to determine whether or not the electric combination 34a of the lower working port 34 is in the electric open state, and a third initial value counter used for setting an initial value of the electric random number counter C4. CN3 is used. The counters C1 to C3, CN1, CN2, CS, C4, and CN3 are provided in the lottery counter area 104a of the RWM 104.

  Each of the counters C1 to C3, CN1, CN2, CS, C4, and CN3 is a loop counter that adds 1 to the previous value every time it is updated, and returns to 0 after reaching the maximum value. Each counter is updated at short intervals. The information corresponding to the jackpot random number counter C1, the jackpot type counter C2 and the reach random number counter C3 is stored in the RWM 104 as an acquisition information storage means when a winning to the upper working port 33 or the lower working port 34 occurs. It is stored in the area 104b.

  The holding storage area 104b includes a holding area RE and an execution area AE. The holding area RE includes a first holding area RE1, a second holding area RE2, a third holding area RE3, and a fourth holding area RE4, and matches the winning history to the upper operating port 33 or the lower operating port 34. The numerical information of the jackpot random number counter C1, the jackpot type counter C2 and the reach random number counter C3 is stored in one of the holding areas RE1 to RE4 as holding information.

  In this case, in the first reservation area RE1 to the fourth reservation area RE4, when the winning to the upper operation port 33 or the lower operation port 34 is continuously generated a plurality of times, the first reservation area RE1 → the second reservation area. Each numerical information is stored in time series in the order of RE2 → third reserved area RE3 → fourth reserved area RE4. By providing the four holding areas RE1 to RE4 as described above, up to four game balls winning histories to the upper operating port 33 or the lower operating port 34 are stored on hold.

  Note that the number that can be reserved and stored is not limited to four, but may be any other number such as two, three, or five or more.

  The execution area AE is an area for moving each value stored in the first holding area RE1 of the holding area RE when starting the variable display on the main display unit 43, and at the start of one game round. Based on various numerical information stored in the execution area AE, determination of whether or not is made is performed.

  Each counter will be described in detail.

  The jackpot random number counter C1 is configured such that one by one is added in order within a range of 0 to 599, for example, and after reaching the maximum value, returns to 0. When the jackpot random number counter C1 makes one round, the value of the first initial value counter CN1 at that time is read as the initial value of the jackpot random number counter C1. The first initial value counter CN1 is a loop counter similar to the big hit random number counter C1 (value = 0 to 599). The big hit random number counter C1 is periodically updated and stored in the holding storage area 104b at the timing when the game ball wins the upper operation port 33 or the lower operation port 34.

  The value of the random number for winning the big hit is stored as a success / failure table in a success / failure table storage area as a success / failure information group storage means in the ROM 103. As the success / failure table, a success / failure table for the low probability mode and a success / failure table for the high probability mode are set. That is, in the pachinko machine 10, the low probability mode and the high probability mode are set as the lottery modes in the success / failure lottery means.

  In the gaming state in which the winning / failing table for the low probability mode is referred to at the time of the lottery, the number of random numbers that win the jackpot is two. On the other hand, in the gaming state in which the winning / failing table for the high probability mode is referred to at the time of the lottery, the number of random numbers that will win the jackpot is 20. If the winning probability in the high probability mode is higher than that in the low probability mode, the number of random numbers to be won is arbitrary.

  The jackpot type counter C2 has a numerical range different from that of the jackpot random number counter C1, and is set to be narrower than the jackpot random number counter C1. Specifically, 1 is added in order within the range of 0 to 29, and after reaching the maximum value, it returns to 0. When the jackpot type counter C2 makes one round, the value of the second initial value counter CN2 at that time is read as the initial value of the jackpot type counter C2. The second initial value counter CN2 is a loop counter similar to the big hit type counter C2 (value = 0 to 29). The big hit type counter C2 is periodically updated and stored in the holding storage area 104b at the timing when the game ball wins the upper operation port 33 or the lower operation port 34.

  In the pachinko machine 10, a plurality of jackpot results are set. Specifically, (1) a mode of opening / closing control of the variable winning device 32 in the opening / closing execution mode, (2) a lottery mode in the winning lottery means after the opening / closing execution mode ends, and (3) a lower operation port after the opening / closing execution mode ends. A plurality of jackpot results are set by providing a difference in the three conditions of the support mode in the 34 electric accessories 34a.

  As an aspect of the opening / closing control of the variable prize winning device 32 in the opening / closing execution mode, it is possible to increase the occurrence frequency of winning in the variable prize winning device 32 between the start and end of the opening / closing execution mode relatively high. A frequency winning mode and a low frequency winning mode are set. Specifically, in any of the high-frequency winning mode and the low-frequency winning mode, the game is executed with a predetermined number of round games as an upper limit.

  Here, the round game is continued until either one of a predetermined upper limit continuation time elapses and a predetermined upper limit number of game balls win a prize winning opening 32a is satisfied. It is a game to play. In addition, the number of round games in the opening / closing execution mode triggered by the jackpot result is the same for a fixed number of rounds regardless of the type of jackpot result triggered by the transition. Specifically, the upper limit number of round games is set to 15 rounds regardless of which jackpot result is obtained.

  Moreover, in this pachinko machine 10, a plurality of types of opening modes of the variable winning device 32 are set with different opening durations from when the big winning opening 32a is opened until it is closed. Specifically, a long-time mode set to 29 sec, which is a long open duration, and a short-time mode set to 0.6 sec, which is a short time shorter than the above long time, are set. Has been.

  In the pachinko machine 10, in a situation where the launch handle 54 is operated by the player, the game ball launching mechanism 53 is driven and controlled so that one game ball is launched toward the game area in 0.6 sec. . In the round game, the upper limit number of end conditions is set to nine. Then, in the long time mode among the above open modes, the open duration time is set longer than the product of the game ball firing period and one round game. On the other hand, in the short-time mode, an opening continuation time is set that is shorter than the product of the game ball launch cycle and one round game, more specifically, shorter than the game ball launch cycle. Therefore, when the variable winning device 32 is opened once in a long-time manner, it is expected that the maximum number of winnings in one round game will be generated at the large winning opening 32a. When the variable winning device 32 is opened once in a short-time manner, it is expected that no winning will be made to the big winning opening 32a or even if a winning will occur.

  In the high-frequency winning mode, the large winning opening 32a is opened once in a round manner in each round game. On the other hand, in the low frequency winning mode, the large winning opening 32a is opened once in each round game in a short time mode.

  It should be noted that the number of times of opening / closing the large winning opening 32a in the high frequency winning mode and the low frequency winning mode, the number of round games, the opening duration for one open and the upper limit number in one round game are those in the high frequency winning mode. However, the value is not limited to the above value as long as the frequency of occurrence of winning in the variable winning device 32 is higher than that in the low-frequency winning mode until the opening / closing execution mode starts and ends. It is.

  As a support mode for the electric combination 34a of the lower working port 34, the electric combination 34a of the lower working port 34 is compared when the game ball is continuously being fired in the same manner with respect to the game area. High frequency support mode (high frequency support state or high frequency guide state) and low frequency support mode (low frequency support state or low frequency guide state) so that the frequency of the open state per unit time is relatively high or low. And are set.

  Specifically, in the low-frequency support mode and the high-frequency support mode, the probability of winning in the power combination open state in the power combination open lottery using the power combination random number counter C4 is the same (for example, both 4/5). However, in the high-frequency support mode, the number of times that the electric accessory 34a is opened when the electrified open state is won is set more than in the low-frequency support mode. Is set longer. In this case, in the high frequency support mode, when the electrified open state is selected and the open state of the electric accessory 34a occurs a plurality of times, the closure from the end of one open state until the start of the next open state is performed. The time is set shorter than one opening time. Furthermore, in the high frequency support mode, a shorter time is secured as a minimum secured time after the next electric character opening lottery is performed after the electric character object opening lottery is performed than in the low frequency support mode. Is set to be selected.

  As described above, in the high frequency support mode, there is a higher probability of winning a prize for the lower working port 34 than in the low frequency support mode. In other words, in the low frequency support mode, there is a higher probability that a prize will be given to the upper working port 33 than to the lower working port 34, but in the high frequency support mode, the lower working port 34 is connected to the lower working port 34. The probability of winning a prize increases. When a winning is made to the lower working port 34, a predetermined number of game balls are paid out. Therefore, in the high frequency support mode, the player plays a game while not reducing the number of possessed balls so much. be able to.

  The configuration for increasing the frequency at which the high frequency support mode is set to the power release state per unit time as compared with the low frequency support mode is not limited to the above-described configuration, for example, the electric component release lottery It is good also as a structure which makes high the probability that it will be elected in the electric character open state in. In addition, a secured time (e.g., on the display part 44 for an accessory based on a winning to the through gate 35) that is secured after the next electric character opening lottery is performed after the electric character releasing lottery is performed once. In the configuration in which multiple types of variable display time) are prepared, the short support time is more easily selected in the high frequency support mode or the average secure time is shorter than in the low frequency support mode. May be. Further, the number of times of opening is increased, the opening time is lengthened, and the secured time that is secured when the next electric winning combination opening lottery is performed after the first electric winning combination releasing lottery is shortened (that is, , Shorten the one time variable display time in the display 44 for an accessory), shorten the average time of the reserved time and increase the winning probability, apply any one condition or any combination of conditions Thus, the advantage of the high frequency support mode over the low frequency support mode may be increased.

  The game result distribution destination for the big hit type counter C2 is stored in the distribution table storage area as the distribution information group storage means in the ROM 103 as a distribution table. And as such a distribution destination, a low probability big hit result, a low winning high probability big hit result, and the most advantageous big hit result are set.

  The low probability big hit result is a big hit result in which the open / close execution mode becomes the high-frequency winning mode, and after the open / close execution mode ends, the win / fail lottery mode becomes the low probability mode and the support mode becomes the high frequency support mode. However, the high-frequency support mode shifts to the low-frequency support mode when the number of games reaches the end reference number (specifically, 100 times) after the shift.

  The low-winning high-probability jackpot result is a jackpot result in which the opening / closing execution mode becomes the low-frequency winning mode, and after the opening / closing execution mode ends, the winning lottery mode becomes the high probability mode and the support mode becomes the high-frequency support mode is there. These high-probability mode and high-frequency support mode are continued until the lottery result in the success / failure lottery becomes a big hit state win and shifts to the big win state by that.

  The most advantageous jackpot result is a jackpot result in which the opening / closing execution mode becomes the high-frequency winning mode, and after the opening / closing execution mode ends, the winning / raising lottery mode becomes the high probability mode and the support mode becomes the high-frequency support mode. These high-probability mode and high-frequency support mode are continued until the lottery result in the success / failure lottery becomes a big hit state win and shifts to the big win state by that.

  Note that the normal game state in relation to each of the above-described game states refers to a state in which the success / failure lottery mode is the low probability mode and the support mode is the low frequency support mode, not the open / close execution mode. Moreover, it is good also as a structure in which the low prize-winning high probability hit result is not set as a game result.

  In the distribution table, among the values of the big hit type counter C2 of “0 to 29”, “0 to 9” corresponds to the low probability big hit result, and “10 to 14” corresponds to the low winning high probability big hit result. “15 to 29” corresponds to the most favorable jackpot result.

  As a kind of high-accuracy big hit result, the open / close execution mode becomes the low-frequency winning mode, and after the open / close execution mode ends, the winning lottery mode becomes the high probability mode, and the support mode is maintained in the previous mode. An unspecified low-winning high-precision jackpot result may be included. In this case, the jackpot result can be further diversified.

  Furthermore, as a kind of losing result in the winning / losing lottery, there may be included a special losing result that shifts to the opening / closing execution mode of the low-frequency winning mode and that does not shift to the winning / losing lottery mode and the support mode after the completion. . In the configuration in which both the above-mentioned non-explicit low winning high probability winning result and the special outlier result are set, the opening / closing execution mode shifts to the low frequency winning mode, and the support mode is changed to the previous mode. It is common to be maintained in the mode, but the transition mode of the winning / failing lottery mode is different, so that, for example, in the normal gaming state, one of the unclear low winning high probability winning result or the special outage result When it occurs, it is possible to make the player predict which result it actually corresponds to.

  The reach random number counter C3 has a numerical range different from that of the big hit random number counter C1 and the big hit type counter C2, and the numerical range is narrower than that of the big hit random number counter C1, and the numerical range is set wider than that of the big hit type counter C2. Specifically, 1 is added in order within the range of 0 to 238, and after reaching the maximum value, the configuration returns to 0. The reach random number counter C3 is periodically updated, and stored in the holding storage area 104b at the timing when the game ball wins the upper operation port 33 or the lower operation port 34.

  Here, in the pachinko machine 10, reach display is set as a kind of display effect in the symbol display device 41. The reach display includes a symbol display device 41 that can perform variable display of symbols, and in game times in which the open / close execution mode of the variable winning device 32 is the high-frequency winning mode, the stop display result after the variable display is specially displayed. In the resulting gaming machine, the player is assumed to be in the variable display state in which the special display result is likely to be obtained before the stop display result is derived and displayed after the variable display of the symbol on the symbol display device 41 is started. The display state for this purpose.

  In the reach display, a combination of jackpot symbols corresponding to the occurrence of the high-frequency winning mode is achieved by stopping and displaying the symbols for some of the symbol rows displayed on the display surface G of the symbol display device 41. A display state is displayed in which combinations of reach symbols that are likely to be established are displayed, and in that state, symbols in the remaining symbol rows are displayed in a variable manner. In addition, in the state where the combination of reach symbols is displayed as described above, the variation display of symbols is performed in the remaining symbol columns, and a reach effect is performed by displaying a predetermined character or the like as a moving image in the background image. In addition, there are those that perform a reach effect by displaying a predetermined character or the like as a moving image on substantially the entire display surface after reducing or not displaying a combination of reach symbols.

  The reach display is executed regardless of the value of the reach random number counter C3 in the game times that shift to the opening / closing execution mode that becomes the high-frequency winning mode. Further, in the game times that do not shift to the opening / closing execution mode, the reach random number counter C3 acquired at a predetermined timing with reference to the reach table stored in the reach table storage area of the ROM 103 corresponds to the occurrence of the reach display. It is executed when

  The variation type counter CS has a numerical range different from that of the big hit random number counter C1 and the big hit random number counter C2, and has a smaller numerical range than the big hit random number counter C1 and a wider numerical range than the big hit type counter C2. Specifically, 1 is added in order within the range of 0 to 198, and after reaching the maximum value, it returns to 0. The variation type counter CS is used when the MPU 102 determines the variation display time on the main display unit 43 and the symbol variation display time on the symbol display device 41. The variation type counter CS is updated in each of a main process and a timer interrupt process, which will be described later. The variation type counter CS is used for determining a variation pattern at the start of variation display in the main display unit 43 and at the time of variation variation of the symbol by the symbol display device 41. The value of CS is acquired. In determining the variable display time, the variable display time table stored in advance in the variable display time table storage area of the ROM 103 is referred to.

  The electric role random number counter C4 is different in numerical range from the big hit random number counter C1 and the big hit random number counter C2, has a smaller numerical range than the big hit random number counter C1, and has a larger numerical range than the big hit type counter C2. . Specifically, 1 is added in order within the range of 0 to 250, and after reaching the maximum value, it returns to 0. Further, when the electric random number counter C4 makes one round, the value of the third initial value counter CN3 at that time is read as the initial value of the electric random number counter C4. The third initial value counter CN3 is a loop counter similar to the electric random number counter C4 (value = 0 to 250). The electric role random number counter C4 is periodically updated and stored in the electric role reservation area 104c provided in the RWM 104 at the timing when a game ball wins the through gate 35. Then, at a predetermined timing, a lottery is performed as to whether or not to control the electric accessory 34a to the open state based on the value of the stored electric random number counter C4.

<About various processes executed by the MPU 102>
Next, each process performed in order to advance a game in MPU102 is demonstrated. The processing of the MPU 102 is roughly classified into main processing that is started when the power is turned on and timer interrupt processing that is periodically started.

<Main processing>
First, the main process will be described with reference to the flowchart of FIG.

  First, in step S101, power-on wait processing is executed. In the power-on wait process, for example, the process waits without progressing to the next process until 1 sec elapses after the main process is activated. In the subsequent step S102, access to the RWM 104 is permitted, and the internal function register of the MPU 102 is set in step S103.

  Thereafter, in step S104, it is determined whether or not the RWM deletion switch provided in the power supply and launch control device 98 is manually operated. In subsequent step S105, whether or not the power failure flag of the RWM 104 is set to “1” is determined. Determine whether. In step S106, a checksum calculation process for calculating a checksum is executed. In subsequent step S107, whether or not the checksum matches the checksum stored when the power is turned off, that is, the validity of the stored data is checked. judge.

  In the pachinko machine 10, for example, when the RWM data is initialized when the power is turned on, such as when the game hall is started, the power is turned on while the RWM erase switch is pressed. Therefore, if the RWM erase switch is pressed, the process proceeds to step S108. Similarly, when the information on occurrence of power shutdown is not set, or when an abnormality of data stored and held is confirmed by the checksum, the process proceeds to step S108. In step S108, the RWM 104 is cleared as initialization of the RWM 104. Thereafter, the process proceeds to step S109.

  On the other hand, if the RWM erase switch has not been pressed, “1” is set in the power failure flag and the checksum is normal, and the process of step S109 is not executed without executing the process of step S108. Proceed to In step S109, a power-on setting process is executed. In the power-on setting process, a predetermined area of the RWM 104 such as initialization of a power failure flag is set to an initial value, and a command corresponding to the current gaming state is transmitted to the sound control device 82 in order to recognize the current gaming state. To do. Also, a payout initialization command indicating that the RWM initialization of the payout control device 97 should be executed is transmitted to the payout control device 97. Furthermore, an interrupt permission is set to permit the generation of timer interrupt processing.

  Thereafter, the process proceeds to the remaining process of steps S110 to S115. That is, the MPU 102 is configured to periodically execute the timer interrupt process, but a remaining time is generated between one timer interrupt process and the next timer interrupt process. The remaining time varies depending on the processing completion time of each timer interrupt process, but the remaining processes in steps S110 to S115 are repeatedly executed using such irregular time. In this regard, it can be said that the remaining processes in steps S110 to S115 are non-periodic processes executed irregularly.

  In the remaining process, first, in step S110, an interrupt prohibition setting is performed to prohibit the generation of the timer interrupt process. Thereafter, in step S111, a first initial value update process for updating the first initial value counter CN1 is executed, and in step S112, a second initial value update process for updating the second initial value counter CN2 is executed. In step S113, a third initial value update process for updating the third initial value counter CN3 is executed. In step S114, an update process for the variation type counter CS is executed.

  In these update processes, the current numerical information is read from the corresponding counter of the RWM 104, the process of adding 1 to the read numerical information is executed, and then the process of overwriting the reading source counter is executed. In this case, each counter value is cleared to “0” when it reaches the maximum value.

  Thereafter, in step S115, an interrupt permission setting for switching from a state in which the generation of timer interrupt processing is prohibited to a state in which the timer interrupt processing is permitted is performed. If the process of step S115 is performed, it will return to step S110 and will repeat the process of step S110-step S115.

<Timer interrupt processing>
Next, timer interrupt processing will be described with reference to the flowchart of FIG.

  Here, a hardware configuration for periodically executing timer interrupt processing in the MPU 102 will be described. The main control board 101 is provided with a clock circuit as pulse signal output means for outputting a pulse signal at a predetermined cycle, and further, a frequency dividing circuit so as to exist in the middle of a signal path between the clock circuit and the MPU 102. Is provided.

  The frequency dividing circuit functions as a frequency changing unit that changes the cycle of the pulse signal from the clock circuit, and is configured to output a pulse signal for specifying the start timing of the timer interrupt processing by the MPU 102. In other words, the pulse signal is supplied from the frequency dividing circuit to the MPU 102 at intervals of a specific cycle of 4 msec. The MPU 102 executes a process for confirming the occurrence of a specific signal form such as the rise or fall of the pulse signal, and starts and executes the timer interrupt process with at least one condition that the occurrence of the specific signal form is confirmed. To do.

  In this case, when the occurrence of the specific signal form is confirmed in the situation where the start of timer interrupt processing is prohibited, the timer is changed when the interrupt is permitted from the state where the interrupt is prohibited. Interrupt processing is started. In other words, depending on the execution status of the process in the MPU 102, there is a case where the next timer interrupt process is started after 4.1 msec from the start of the previous timer interrupt process. The timer interrupt process may be started after 3.9 msec from the start of the immediately preceding timer interrupt process.

  The case where the timer interrupt process is not started even though 4 msec has elapsed is when the interrupt prohibition is set in step S110 and 4 msec elapses while the remaining process is being executed. . Therefore, the start timing of the timer interrupt process varies depending on the execution status of the residual process.

  However, since the output of the pulse signal from the frequency dividing circuit is performed at a specific cycle of 4 msec regardless of the progress of the processing in the MPU 102, the timer interrupt processing is basically started at a specific cycle. Furthermore, the processing configuration of the MPU 102 is such that the timer interrupt process at a predetermined timing is the timing next to the predetermined timing even if the timer interrupt process is started after a period exceeding a specific period since the previous timer interrupt process was started. In the timer interrupt processing at, the portion exceeding the specific period is absorbed, and the timer interrupt processing at the next timing is set to be started at the timing when the input of the pulse signal is confirmed.

  Note that the mode in which the timer interrupt processing is periodically started is not limited to the above mode and is basically started at a predetermined cycle such as 4 msec. Even if a new timer interrupt process is started after the elapse of the time corresponding to the predetermined period due to the fact that the timing corresponding to the period of the elapses is in the middle of the remaining process, the next timer The interrupt processing may be configured not to be started at a timing before the elapse of time corresponding to a predetermined period after the new timer interrupt processing is started. In other words, the timer interrupt processing is basically started at a predetermined cycle and may be started at an interval exceeding the predetermined cycle in relation to the remaining processing, It is good also as a structure which is not started by an interval. Even in this case, the start interval of the timer interrupt process can vary in relation to the remaining process.

  In the timer interrupt process, first, a power failure information storage process is executed in step S201. In the power outage information storage process, it is monitored whether a power outage signal corresponding to the occurrence of power interruption is received from the power outage monitoring board 105 through the input / output port provided in the MPU 102. Execute time processing.

  In subsequent step S202, a lottery random number update process is executed. In the lottery random number updating process, the big hit random number counter C1, the big hit type counter C2, the reach random number counter C3, and the electric random number counter C4 are updated. Specifically, after executing the process of sequentially reading the current numerical information from the jackpot random number counter C1, the jackpot type counter C2, the reach random number counter C3, and the electric random number counter C4, and adding 1 to each of the read numerical information, A process of overwriting the reading source counter is executed.

  In this case, for the counter whose numerical information reaches the maximum value, the numerical information is cleared to “0” which is the minimum value. Further, for the jackpot random number counter C1, the jackpot type counter C2 and the electric utility random number counter C4, when the numerical information is updated once, the initial value information is read from the corresponding initial value counters CN1 to CN3 and read. The initial value information is overwritten as the initial value for a new lap.

  Here, the jackpot random number counter C1, the jackpot type counter C2 and the reach random number counter C3 will be described later in a state where the game is normally progressing (specifically, a negative determination is made in step S206 described later). It is configured to be executed once for each execution of the special figure special electric control process in step S214. In the special figure special power control process, a process of monitoring a winning at the operating ports 33 and 34 is executed, and when a winning at the operating ports 33 and 34 occurs, a big hit random number counter C1 and a big hit type Processing for obtaining numerical information from the counter C2 and the reach random number counter C3 is executed. Then, based on the acquired numerical information, a success / failure determination process for determining whether or not the jackpot is won, a distribution determination process for distributing the jackpot type, and a reach determination process for determining whether or not a reach has been won are executed.

  In other words, each of the jackpot random number counter C1, the jackpot type counter C2 and the reach random number counter C3 is configured such that the update process of the numerical information is performed once for each opportunity that the numerical information can be acquired. ing. As described above, each of the jackpot random number counter C1, the jackpot type counter C2 and the reach random number counter C3 is assumed that the update cycle is completed once when all target numerical information is set once. Determined. Therefore, if the jackpot winning is generated with the probability set in the design stage of the pachinko machine 10, and if the jackpot winning is generated, the ratio set in the design stage of the pachinko machine 10 is set to any of the jackpot results. Sorted. In addition, when the jackpot is not won, the reach display is generated with the probability set in the design stage of the pachinko machine 10.

  In addition, the electric random number counter C4 is in the normal power transmission control process of step S215 to be described later in a state where the game is normally progressing (specifically, a negative determination is made in step S206 to be described later). It is configured to be executed once for each execution. In the ordinary power transmission control process, a process for monitoring a winning to the through gate 35 is executed, and if a winning to the through gate 35 occurs, numerical information is acquired from the electric random number counter C4. Is executed. Then, based on the acquired numerical information, a determination process is performed as to whether or not the electric accessory 34a is to be opened.

  That is, the electronic random number counter C4 is configured such that the update process of the numerical information is performed once in response to one time when the numerical information can be acquired. Then, as described above, the electronic random number counter C4 determines that the update cycle has been completed once when all target numerical information is set once. Therefore, the winning combination of the electric accessory 34a occurs with the probability set in the design stage of the pachinko machine 10.

  Thereafter, in step S203, various initial value update processes are executed. In various initial value update processing, processing similar to that in steps S111 to S113 is executed. In step S204, the update process of the variation type counter CS is executed as in step S114.

  In a succeeding step S205, a game stop determination process is executed. In the game stop determination process, the detection result in the magnet detection sensor 109 is read through an input / output port provided in the MPU 102, and it is determined whether or not the detection result corresponds to the occurrence of fraud. Further, it is determined whether or not fraud is detected in step S211 in the previous timer interrupt process. If an affirmative determination is made in any of these determination processes, it is specified that the game progress should be stopped, and if a negative determination is made in both of these determination processes, the game progress Identify that the situation should not be stopped.

  Thereafter, in step S206, it is determined whether or not the progress of the game is stopped, and the processing after step S207 is executed on the condition that the progress of the game is not stopped.

  In step S207, port output processing is executed. In the port output process, when the output information is set in the previous timer interrupt process, a process for performing output corresponding to the output information to the various drive units 107 and 108 is executed. For example, when the information for switching the special winning opening 32a to the open state is set, the output of the drive signal to the variable winning drive unit 107 is started, and when the information for switching to the closed state is set. The output of the drive signal is stopped. When the information for switching the electric accessory 34a of the lower working port 34 to the open state is set, the output of the drive signal to the accessory driving unit 108 is started, and the information to be switched to the closed state is set. If so, output of the drive signal is stopped.

  In a succeeding step S208, a reading process is executed. In the reading process, signals other than the power failure signal and the winning signal are read, and the read information is stored for use in future processing.

  In subsequent step S209, a winning detection process is executed. In the winning detection process, the signals received from the winning detection sensors 106a to 106h are read, and the general winning port 31, the large winning port 32a, the upper operating port 33, the lower operating port 34 and the through gate 35 are used for winning. A process for identifying the presence or absence is executed.

  In the subsequent step S210, timer update processing for updating the numerical information of a plurality of types of timer counters provided in the RWM 104 is executed. In this case, the timer counter that is updated by subtracting the stored numerical information is handled in an integrated manner. However, both the updating of the subtracting timer counter and the updating of the adding timer counter are performed collectively. It is good also as a structure.

  In subsequent step S211, a fraud detection process for monitoring whether or not a predetermined event set as a fraud monitoring target has occurred is executed. In the fraud detection process, the occurrence of a plurality of types of events is monitored, and a predetermined event has occurred (for example, a vibration detection sensor (not shown) detects vibration, or a radio detection sensor (not shown) By confirming that the game has been detected), the game stop is set in step S205 in the next timer interruption process, and an affirmative determination is made in step S206.

  In the subsequent step S212, a launch control process for controlling the launch of the game ball is executed. In a situation where the firing operation is continued with respect to the firing handle 54, as already described, one game ball is launched at a predetermined firing period of 0.6 sec.

  In the subsequent step S213, as the input state monitoring process, the disconnection confirmation of the winning detection sensors 106a to 106h and the opening confirmation of the gaming machine main body 12 and the front door frame 14 are confirmed based on the information read in the reading process in step S208. Do.

  In the subsequent step S214, special figure special electric control processing for performing execution control of game times and execution control of the opening / closing execution mode is executed. The contents of the special figure special electric control process will be described later.

  In the subsequent step S215, the ordinary power control process is executed. In the ordinary map / electric power control process, when a winning to the through gate 35 is generated, a process for acquiring the retained information on the ordinary map side is executed and the retained information on the ordinary map side is stored. In addition, a release determination is performed on the hold information, and a process for performing an effect for a normal diagram is executed using the release determination as a trigger. Moreover, the process which opens and closes the electrically-driven accessory 34a of the lower working port 34 based on the result of opening determination is performed.

  In subsequent step S216, based on the processing results of immediately preceding step S214 and step S215, setting of output information for reflecting the increase / decrease number of the hold information related to the main display unit 43 in the first hold light emitting unit 45, and The output information for reflecting the increase / decrease number of the hold information related to the accessory display unit 44 to the second hold light emitting unit 46 is set. In step S216, the output information for updating the display content of the main display unit 43 is set based on the processing results of the immediately preceding steps S214 and S215, and the display content of the accessory display unit 44 is set. Set the output information to be updated.

  In the subsequent step S217, a demonstration display process is performed to make the display content of the symbol display device 41 for standby display in a situation where neither the game times nor the opening / closing execution mode is executed, and in step S218, Then, the contents of the command and signal received from the payout control device 97 are confirmed, and a payout state receiving process for performing a process corresponding to the confirmation result is executed. In step S219, a payout output process for setting a prize ball command as an output target is executed.

  In subsequent step S220, an external information setting process for controlling the start and end of the output of the external signal in accordance with the processing results of the various processes executed in the current timer interrupt process is executed. In step S221, a process for editing the test fire test information is executed.

  When an affirmative determination is made in step S206, or after the processing of steps S207 to S221 is executed, the process proceeds to step S222. In step S222, an interrupt end declaration is set. The MPU 102 stipulates that once timer interrupt processing is started, an interrupt end declaration is set as one of the conditions for starting the next timer interrupt processing. In step S222, the next timer interrupt processing is set. Set interrupt termination declaration to enable execution of interrupt processing. In step S223, interrupt permission is set. In the MPU 102, once the timer interrupt processing is started, the interrupt is disabled. Therefore, in step S223, interrupt permission is set to enable execution of the next timer interrupt processing. Thereafter, the timer interrupt process is terminated.

<Special Figure Special Electric Control Process>
Next, the special figure special power control process executed in step S214 of the timer interrupt process (FIG. 9) will be described with reference to the flowchart of FIG.

  In the special figure special electric control process, when a winning to the upper working port 33 or the lower working port 34 is generated, a process for acquiring the holding information is executed and when the holding information is stored, the holding is performed. A determination is made as to whether or not the information is correct, and further, a process for performing an effect for game times is executed using the determination as to whether or not the information is correct. In addition, based on the result of the determination, the processing for shifting to the opening / closing execution mode after the effect for playing the game is executed, and the processing during the opening / closing execution mode and at the end of the opening / closing execution mode is executed.

  Specifically, first, hold information acquisition processing is executed in step S301. In the hold information acquisition process, it is determined whether or not a prize has been generated for the upper working port 33 or the lower working port 34. If a winning has occurred, the reserved information is stored in the reserved number storage area NA in the reserved storage area 104b. The stored number of holds is read, and it is determined whether or not the number of holds is less than the upper limit value (“4” in the present embodiment). When the number of holds is less than the upper limit, the number of holds is incremented by 1 and the numerical information of the jackpot random number counter C1, the jackpot type counter C2 and the reach random number counter C3 updated in the previous step S202 is used for holding. Stored in the first reserved area among the empty reserved areas RE1 to RE4 of the area RE.

  In addition, when winning to the upper working port 33 and the lower working port 34 occurs at the same time, the process for obtaining the hold information is performed a plurality of times within a range in which the hold information obtaining process is executed once. Run.

  After executing the hold information acquisition process in step S301, the process proceeds to step S302. In step S <b> 302, a process of reading information of a special figure special electricity counter provided in the RWM 104 is executed. In a succeeding step S303, a process of reading the special figure special power address table from the ROM 103 is executed. In step S304, a process of acquiring a start address corresponding to the information of the special figure special power counter from the special figure special electric address table is executed.

  Here, the processing content of step S302-step S304 is demonstrated.

  As already described, the special figure special power control process includes a process related to a game-playing effect and a process related to an opening / closing execution mode. In this case, as processing related to the effect for game times, special figure variation start processing (step S306) which is processing for starting the effect for game times and processing for proceeding the effect for game times. A special figure changing process (step S307) and a special figure finalizing process (step S308) which is a process for ending the effect for the game round are set.

  In addition, as processing related to the opening / closing execution mode, special electricity starting processing (step S309) which is processing for controlling the opening of the opening / closing execution mode, and special electricity which is processing for controlling the open state of the special winning opening 32a. Opening process (step S310), special electricity closing process (step S311) which is a process for controlling the closed state of the special winning opening 32a, opening / closing execution mode ending and gaming state at the end of the opening / closing execution mode Special electric power ending process (step S312), which is a process for controlling the transition, is set.

  In such a processing configuration, the special figure special power counter is a counter for the MPU 102 to grasp which of the above-mentioned plural types of processing should be executed. Corresponding to the numerical information of the special electric counter, the start address of the program for executing the above-mentioned plural types of processing is set.

  In this case, the start address SA0 is the start address of the program for executing the special figure variation start process (step S306), and the start address SA1 is the program address for executing the special figure variation process (step S307). The start address SA2 is the start address of the program for executing the special figure finalizing process (step S308), and the start address SA3 is the program address for executing the special electricity start process (step S309). The start address SA4 is a start address of a program for executing the special power open process (step S310), and the start address SA5 is a program for executing the special power close process (step S311). This is the start address, and the start address SA6 A start address of a program for executing (step S312).

  The special figure special electric power counter is the special figure special electric power control in the next processing time when the condition for updating the numerical information is satisfied when the processing corresponding to the numerical information currently stored is completed. Corresponding to the processing executed in the processing, 1 addition, 1 subtraction, or “0” is cleared (initialized). Therefore, in the special figure special power control process at each processing time, a process corresponding to the numerical information set in the special figure special electric power counter may be executed.

  According to the above configuration, it is possible for the MPU 102 to grasp which process is to be executed as the special figure special power control without checking the presence or absence of various flags. For example, an effect for game times starts when no other game times effect is executed and is not in the opening / closing execution mode. In the process related to the effect, before starting the effect for the game turn, whether or not the flag indicating that the effect for the game turn is being executed is set, and the opening / closing execution mode is being executed. It is necessary to check whether or not a flag indicating that is set. In addition, during the execution of the game-turn effect, a flag indicating that the flag indicating that the game-turn effect is being executed is set and a confirmation display is set. It is necessary to check whether or not

  In addition, the opening / closing execution mode is started when the effect for the game round is finished and the other opening / closing execution modes are not executed. In the process, before starting the opening / closing execution mode, it is confirmed whether or not a flag indicating that the effect for playing the game has ended is set, and a flag indicating that the opening / closing execution mode is being executed is set. It is necessary to confirm whether or not it is being performed. Further, when the opening is being performed, it is necessary to confirm whether or not a flag indicating that the opening is being performed is set. In addition, after the opening, it is confirmed whether or not a flag indicating that the opening / closing execution mode is being executed is set, and whether or not a flag indicating that the special winning opening 32a is being opened is set. It is necessary to confirm whether or not. Furthermore, when the ending is in progress, it is necessary to check whether or not a flag indicating that the ending is in progress is set.

  On the other hand, if a special figure special electricity counter is used, it is not necessary to prepare various flags, and information for checking the execution timing of each process is also collected. Therefore, the process can be simplified.

  After executing the process of step S304, a process of jumping to the process indicated by the start address acquired in step S304 is executed in step S305. Specifically, if the acquired start address is SA0, the process jumps to the special figure change start process in step S306.

  In the special figure change start process, on the condition that the hold information is stored on hold, if the hold information corresponds to the jackpot winning, and if the hold information corresponds to the jackpot winning Executes a distribution determination process for determining which jackpot result the hold information corresponds to. In the determination process, whether or not the numerical information acquired from the jackpot random number counter C1 in the hold information is numerical information corresponding to the jackpot winning is determined. In the distribution determination process, it is determined whether the numerical information acquired from the jackpot type counter C2 in the hold information corresponds to which jackpot result category.

  In addition to the success / failure determination process and the distribution determination process, when the hold information does not correspond to the big win, the reach determination process is performed to determine whether or not the hold information corresponds to the occurrence of reach. Then, the duration selection process for selecting the duration of the game times is executed using the numerical information of the variation type counter CS at that time. In the reach determination process, it is determined whether or not the numerical information acquired from the reach random number counter C3 in the hold information corresponds to the numerical information on the occurrence of reach.

  When the duration information is selected, the variation command including the duration information and the type command including the game result information are transmitted to the sound control device 82, and the variation of the pattern in the main display unit 43 is transmitted. Start display. As a result, one game is started, and an effect for the game is started on the main display unit 43 and the symbol display device 41.

  By the way, when the effect for the game round is started in this way, the numerical information of the special figure special electric counter is incremented by 1 so that the numerical information of the counter corresponds to the special figure variation start process. Update to the one corresponding to the changing process.

  If the acquired start address is SA1, the process jumps to the special figure changing process of step S307. In the special figure changing process, a process of determining whether or not it is during the game time duration and before the fixed display is performed, and before the fixed display, the display mode of the picture on the main display unit 43 A process for regularly changing is executed.

  By the way, instead of waiting in the special figure changing process until it is the timing to display the fixed figure, if it is not the timing to make a fixed display, the process for changing the regular figure is executed and then the special figure is changing. The process ends. Therefore, after the game-turn effect is started, the special-figure changing process is started every time the special-figure special-electric control process is started until the timing for final display is reached. In addition, when it is time to confirm and display, the numerical information of the special figure special electric counter is incremented by 1, so that the numerical information of the counter corresponds to the special figure in-flight process from the one corresponding to the special figure changing process Update to what you did.

  If the acquired start address is SA2, the process jumps to the special figure determining process in step S308. In the special figure finalizing process, the final display command is transmitted to the sound control device 82 in order to cause the symbol display device 41 to display the final stop result of the current game round, and the main display unit 43 displays the pattern. The mode is a display mode corresponding to the result of the current game round. In the special figure confirmation process, it is determined whether or not the period during confirmation display has elapsed, and if the period has elapsed, it is determined whether or not the transition to the opening / closing execution mode occurs. When the transition to the opening / closing execution mode occurs, the mode transition process is executed.

  By the way, instead of waiting in the special figure determination process until the fixed display period elapses, this special figure determination process is terminated if the period has not elapsed. Therefore, after the fixed display is started, the special figure determination process is started each time the special figure special power control process is started until the period during the fixed display elapses. In addition, when the period during the fixed display has elapsed, in a situation where the transition to the opening / closing execution mode does not occur, the numerical information of the special figure special counter is initialized (that is, “0” is cleared) and the transition to the opening / closing execution mode is performed. In such a situation, by adding 1 to the numerical information of the special figure special power counter, the numerical information of the counter is updated from the one corresponding to the special figure determination process to the one corresponding to the special electric power start process.

  If the acquired start address is SA3, the process jumps to the special electricity start process in step S309. In the special electricity start process, an opening command indicating that the opening / closing execution mode is started is transmitted to the sound control device 82. In the special electricity start process, it is determined whether or not the opening period of the opening / closing execution mode has elapsed. When the opening period has not elapsed, this special power start process is terminated instead of waiting in the special power start process. Therefore, after the opening effect in the opening / closing execution mode is started, the special power start process is started each time the special figure special power control process is started until the opening period elapses. In addition, when the opening period has elapsed, the numerical information of the special figure special power counter is incremented by 1, thereby updating the numerical information of the counter from the one corresponding to the special power start process to the one corresponding to the special power open process. .

  If the acquired start address is SA4, the process jumps to the special power release releasing process in step S310. In the special electric release opening process, one round game is started, and it is determined whether or not the end condition of the round game is satisfied. When the end condition is not satisfied, the process is not waited for in the special electricity release process, but the process for monitoring the establishment of the end condition is executed, and then the special electricity release process is terminated. When the above termination condition is satisfied, the numerical information of the special figure special power counter is incremented by 1, so that the numerical information of the counter is changed from the one corresponding to the special electric power open process to the one corresponding to the special electric power closed process. Update.

  If the acquired start address is SA5, the process jumps to the special electricity closing process in step S311. In the special electricity closing process, a process of ending one round game is executed. Further, in the interval period between round games, it is determined whether or not the interval period has elapsed. When the interval period has not elapsed, this special electric power closing process is terminated instead of waiting in the special electric power closing process. Therefore, when the interval period is started, the special power closing process is started each time the special figure special electric control process is started until the period elapses. In addition, when the interval period has elapsed, by subtracting 1 from the numerical information of the special figure special electricity counter, the numerical information of the counter is updated from the one corresponding to the special electric current closing process to the one corresponding to the special electric current opening process. To do.

  On the other hand, in the special power shut-off process for the last round game, after executing the process of ending one round game, the numerical information of the special figure special power counter is incremented by 1 so that the numerical information of the counter is changed to the special power shut-off process. Update from the corresponding one to the one corresponding to the special electricity termination processing.

  If the acquired start address is SA6, the process jumps to the special power end process in step S312. In the special electric power end process, an ending command indicating that the open / close execution mode is ended is transmitted to the sound control device 82. In the special electric power end process, it is determined whether or not the ending period of the opening / closing execution mode has elapsed. If the ending period has not elapsed, the special electric power end processing is terminated instead of waiting in the special electric power end processing. Therefore, after the ending effect in the opening / closing execution mode is started, the special electric power end process is started every time the special figure special electric control process is started until the ending period elapses. In addition, when the ending period has elapsed, after executing processing for setting the gaming state (open / close lottery mode and support mode) after the opening / closing execution mode, the numerical information of the special figure special electricity counter is initialized. Then, the numerical information of the counter is updated from the one corresponding to the special electricity end process to the one corresponding to the special figure change start process.

<Countermeasures against fraudulent actions regarding the acquisition of numerical information>
Here, in the pachinko machine 10, the fact that the jackpot random number counter C1 is predetermined numerical information is illegally read, and further, based on the read result, the numerical information of the jackpot random number counter C1 corresponds to the numerical information corresponding to the jackpot. At this timing, it is assumed that an act of illegally shifting to the opening / closing execution mode is performed by setting a state as if a winning to the operation ports 33 and 34 has occurred. Hereinafter, a configuration for preventing the fraud will be described.

  Prior to the description of the configuration for countermeasures against the fraud, how the fraud is performed will be described with reference to FIG. FIG. 11 is a block diagram for explaining an electrical configuration when a signal is input from the outside of the MPU 102 in the MPU 102.

  As shown in FIG. 11, the MPU 102 is provided with an input / output port 102 a for receiving a signal from the outside of the MPU 102 and transmitting a signal to the outside of the MPU 102. The input / output port 102a is provided with a predetermined number (specifically, eight) of terminals, and the input / output port 102a is used for input according to the state of a predetermined flag provided in a register in the MPU 102. Switching between the state and the state for output.

  In a situation where the input / output port 102 a is in an input state, the MPU 102 receives various signals from outside the MPU 102. The type of this signal is as described above, and a signal corresponding to the presence or absence of the occurrence of a power failure is received from the power failure monitoring board 105, and the winning detection result is received from each of the various winning detection sensors 106a to 106h (see FIG. 6). And a signal corresponding to the magnetism detection result is received from the magnet detection sensor 109. Besides these, signals are received. The number of types of signals to be input is larger than the number of terminals provided in the input / output port 102a.

  Corresponding to this, the main control board 101 is provided with a first port driver 101a and a second port driver 101b, and signals to be input are input to the port drivers 101a and 101b. It is the composition which becomes. The number of types of signals input to the first port driver 101a is equal to or less than the number of terminals of the input / output port 102a, and the number of types of signals input to the second port driver 101b is also the input / output. The number is less than or equal to the number of terminals of the port 102a.

  In this case, the power failure monitoring board 105 is electrically connected to the first port driver 101a through the first signal path LN1, and a power failure signal from the power failure monitoring board 105 (when no power failure is detected). One of HI and LOW, or the other of HI and LOW when a power failure is detected) is input to the first port driver 101a. In addition, the magnet detection sensor 109 is electrically connected to the second port driver 101b through the second signal path LN2, and the magnet detection signal from the magnet detection sensor 109 (when magnetism is not detected). Is one of HI and LOW, and is the other of HI and LOW when magnetism is detected) is input to the second port driver 101b.

  The first port driver 101a and the second port driver 101b are electrically connected to the input / output port 102a through the third signal path LN3. In this case, in the third signal path LN3, the signal path continuing from the first port driver 101a and the signal path continuing from the second port driver 101b merge at a midway position, and the signal path after the merge is the input / output port. 102a.

  The MPU 102 is electrically connected to the first port driver 101a through a fourth signal path LN4 different from the third signal path LN3, and is a fifth signal path LN5 different from the third signal path LN3. Through the second port driver 101b. When a signal is output from the MPU 102 to the first port driver 101a through the fourth signal path LN4, a signal output source in which a signal to be received by the MPU 102 is connected to the first port driver 101a. It becomes the signal from. On the other hand, when the MPU 102 outputs a signal to the second port driver 101b through the fifth signal path LN5, the signal to be received by the MPU 102 is connected to the second port driver 101b. It is a signal from the output source.

  In the above configuration, when illegally reading that the jackpot random number counter C1 is predetermined numerical information, for example, the unauthorized device A is electrically connected to each of the fourth signal path LN4 and the fifth signal path LN5. , It is possible to specify whether the MPU 102 is receiving a signal through the first port driver 101a or the MPU 102 is receiving a signal through the second port driver 101b. . Incidentally, when the unauthorized device A existing outside the main controller 81 is electrically connected to the fourth signal path LN4 and the fifth signal path LN5, the unauthorized device A is illegally connected to the board box 83 of the main controller 81. Incorrect connection is made through the holes formed in the above or through the vent holes formed in the substrate box 83.

  In this case, in the above-described timer interrupt process (FIG. 9), there is a power failure information storage process (step S201) and a game stop determination process (step S205) with a lottery random number update process (step S202) interposed therebetween. When the unauthorized device A is electrically connected as described above, the state in which signal output is performed through the fourth signal path LN4 and the state in which signal output is performed through the fifth signal path LN5 It is possible to grasp the time required for the random number update process for lottery (step S202).

In the lottery random number update process, as already described, the update process of the numerical information of the jackpot random number counter C1 is executed.
1. 1. When 1 is added to the numerical information so that the numerical information becomes the numerical information in the next order. 2. When clearing to the minimum value when the result of adding 1 to the numerical information exceeds the maximum value so that the numerical information becomes the numerical information in the next order When the result of adding 1 to the numerical information so that the numerical information becomes the numerical information in the next order is the initial value in the update cycle of the current numerical information, the initial value is newly set from the first initial value counter CN1. When obtaining and setting 1. ~ 3. There are three types of update modes.

  The processing time required for each of these update modes is different. Specifically, the above 1. <2. <3. The processing time becomes longer in this order. Therefore, the above 1. ~ 3. Depending on which one is executed, the processing time required from the execution of the power failure information storage process (step S201) to the execution of the game stop determination process (step S205) also varies.

  Under such circumstances, when the time required for the random number update process for lottery (step S202) is grasped by the unauthorized device A as described above, the update process of the numerical information of the jackpot random number counter C1 is performed as described above. ~ 3. It is possible to specify which one of them is being executed. In particular, the above 2. And 3. In the case of 1. Since the processing time is largely different from that in the case of 1. It is possible to easily specify that other than the above is executed.

  2. Is specified, it is specified that the numerical information of the jackpot random number counter C1 is “0” which is the minimum value. Then, if the ROM 103 of the main control device 81 is illegally acquired, and if the type of numerical information that is won and the update period of the jackpot random number counter C1 is grasped in advance, the jackpot random number counter C1 is set as described above. If the timing at which the numerical information becomes “0” can be acquired, the MPU 102 indicates that the winning detection sensor of the operation ports 33 and 34 has detected a winning at the timing at which the numerical information of the jackpot random number counter C1 becomes the numerical information corresponding to the big win. It becomes possible to specify. In this case, a big win will be generated illegally. It should be noted that the illegal device A is electrically connected to the signal path between the winning detection sensor of the operating ports 33 and 34 and the MPU 102, so that the winning detection sensor of the operating ports 33 and 34 detects the winning at the above timing. Then, the MPU 102 can be specified.

  In the following, a plurality of patterns of the configuration serving as countermeasures against the above fraud will be described.

<First pattern>
First, the configuration of the first pattern that serves as a countermeasure against the fraud will be described.

  FIG. 12 is a flowchart showing the lottery random number update process (step S202) in the first pattern.

  In the lottery random number update process, first, in step S401, a jackpot random number update process for periodically updating the numerical information of the jackpot random number counter C1 is executed. Details of the jackpot random number update process will be described later.

  In step S402, a jackpot type update process for periodically updating the numerical information of the jackpot type counter C2 is executed, and in step S403, a reach random number update for periodically updating the numerical information of the reach random number counter C3. The process is executed, and in step S404, the electric random number update process for periodically updating the numerical information of the electric random number counter C4 is executed. The details of the processing contents in steps S402 to S404 are the same as the processing contents described in step S202. Thereafter, the lottery random number update process is terminated.

  Next, the jackpot random number update process will be described with reference to the flowchart of FIG.

  First, in step S501, the numerical information held in the jackpot random number counter C1 is read to the register of the MPU 102, and in step S502, 1 is added to update the read numerical information to become the next numerical information. After that, in step S503, it is determined whether or not the numerical value information updated in step S502 exceeds the maximum value (specifically “599”) of the jackpot random number counter C1 (specifically “ It is determined whether or not “600” or more).

  If the maximum value is not exceeded (step S503: NO), the time adjustment process (or delay process) is executed in step S504, while if the maximum value is exceeded (step S503: YES), In step S505, the numerical information updated in step S502 is set to the numerical information of the minimum value, specifically “0”.

  Here, the processing for time adjustment in step S504 described above requires processing time when updating the numerical information of the jackpot random number counter C1 by one according to the update order, that is, when adding 1 to the numerical information of the jackpot random number counter C1. When the numerical information exceeding one boundary of the numerical range is set as the other boundary after updating the numerical information by one according to the update order, that is, the numerical information of the jackpot random number counter C1 is set to the minimum value “0” This is a process for bringing the processing time of the jackpot random number update process in the former case closer to the processing time of the jackpot random number update process in the latter case, in a configuration shorter than the processing time required for the case. More specifically, this is a process for making the processing time of the jackpot random number update process in the former case the same or substantially the same as the processing time of the jackpot random number update process in the latter case.

  Specific contents of the time adjustment process will be described in relation to a program counter provided in the register of the MPU 102. FIG. FIG. 13B is an explanatory diagram for explaining the contents of the time adjustment processing in relation to the program counter.

  As shown in FIG. 13B, in the state in which the jackpot random number update process is activated, the data of the program counter is “m”. In this case, the MPU 102 executes the process of step S501 by executing the instruction 1. When the execution of the instruction 1 is completed, the program counter data is incremented by 1 to “m + 1”. In this case, the MPU 102 executes the process of step S502 by executing the instruction 2.

  When the execution of the instruction 2 is completed, the program counter data is incremented by 1 to “m + 2”. In this case, the MPU 102 executes the determination process in step S503 by executing the conditional jump instruction JR.

  When the condition specified by the conditional jump instruction JR is satisfied, the jump instruction JP is executed with the data of the program counter set to “n”. As a result, the MPU 102 reads the instruction 4 corresponding to the program counter data “n” from the ROM 103 and executes the instruction 4. In this case, the process of step S505 is executed. Thereafter, the data of the program counter is incremented by 1 to “n + 1”. In this case, the MPU 102 executes the jump instruction JP1 that sets the data of the program counter to “m + 14”. Thereby, the process after the instruction 3, that is, the process after step S506 is executed.

  When the numerical information is set to the minimum value as described above, first, rewriting the program counter is executed as an instruction, so that the address when reading the program from the ROM 103 is changed to an address different from the address according to the previous order. It needs to be changed. In this process, T is the time required when the program counter is simply incremented by 1 in accordance with the sequence up to that time without executing any process for reading the instruction, that is, the time required for NOP. In some cases, p × T. Further, it is necessary to execute the jumped instruction (step S505). The time required for such processing is q × T. In addition, after executing the instruction, it is necessary to execute the jump instruction again to change the address when the program is read from the ROM 103 to an address different from the address according to the previous order. The time required for such processing is r × T. That is, after making an affirmative determination in step S503 and executing the process of step S505, the time required to shift to the process of step S506 is (p + q + r) × T.

  On the other hand, when the condition specified by the conditional jump instruction JR is not satisfied, 1 is added to the data of the program counter to obtain “m + 3”. In this case, since NOP is set as the instruction, no processing is executed. Thereafter, the NOP is read each time the program counter data is sequentially incremented by 1, so that the state in which no processing is executed is continued. That is, until the program counter data reaches “m + 13”, the MPU 102 simply adds 1 to the program counter data without executing any processing. Then, when the data of the program counter becomes “m + 14”, the process proceeds to step S506.

  The program counter data “m + 3” to “m + 13” corresponds to the time adjustment processing in step S504. In other words, the time adjustment process does not execute the setting process for the data to be referred to by the MPU 102 when the game is advanced, in other words, it affects the content of the signal transmitted from the MPU 102. In this state, the program counter data is simply incremented by one. By the time adjustment process, the time required to make a negative determination in step S503 and shift to the process in step S506 is the same as (p + q + r) × T.

  Specifically, in order to make a negative determination in step S503 and shift to step S504, it is necessary to add 1 to the program counter data, and thus time T is required. Accordingly, in step S504, by executing the program counter instructions “m + 3” to “m + 13”, the progress of the process is waited for a time of (p + q + r−1) × T (note that This time includes the time required to move from step S504 to step S506).

  Returning to the description of FIG. 13A, after the processing of step S504 or step S505 is executed, the numerical information read out by the MPU 102 in step S506 is the current update cycle of the jackpot random number counter C1. It is determined whether or not the numerical information is the same as the initial numerical value. Specifically, the initial value information in the current update cycle stored in the RWM 104 is read, and the numerical information after the processing in step S502 or the numerical information after the processing in step S505 is the same as the initial value information. It is determined whether or not.

  If a negative determination is made in step S506, the numerical value information after the processing in step S502 or the numerical information after the processing in step S505 is overwritten in the big hit random number counter C1 in step S507. Thereafter, the big hit random number update process is terminated.

  On the other hand, if an affirmative determination is made in step S506, the current numerical information held in the first initial value counter CN1 is read in step S508, and the numerical information is read in step S502 in step S509. The numerical information after processing or the numerical information after processing in step S505 is overwritten, and the area for storing the initial value of the update cycle in the RWM 104 is overwritten. Thereafter, in step S507, the numerical information after the processing in step S509 is set by overwriting the big hit random number counter C1, and then the big hit random number update process is terminated.

  According to the configuration of the first pattern, the processing time of the jackpot random number update processing in the case where the numerical information of the jackpot random number counter C1 is sequentially updated toward the maximum value which is one boundary of the numerical range, and the jackpot The processing time of the jackpot random number update processing when the numerical information of the random number counter C1 exceeds one boundary of the numerical range and the numerical information is set to the minimum value that is the other boundary is determined from the outside of the MPU 102. Difficult to identify or impossible to identify. Therefore, even if the processing time required for step S201 to step S205 is illegally read using the illegal device A, the numerical information of the jackpot random number counter C1 is one boundary of the numerical range. It is difficult to specify or cannot be specified. Therefore, even if an illegal profit is obtained based on illegal reading of numerical information of the jackpot random number counter C1, it can be prevented.

  In particular, according to this configuration, the processing time when the numerical information of the jackpot random number counter C1 is set to the minimum value is the processing when the numerical information of the jackpot random number counter C1 is sequentially updated toward one boundary. Even if the processing time required for step S201 to step S205 is read illegally using the unauthorized device A, it is difficult to specify for the time or cannot be specified. It is not possible to specify which numerical information is. Therefore, it is possible to substantially invalidate the fraud.

  Further, the numerical value of the jackpot random number counter C1 is simply increased by increasing the processing time of the jackpot random number update process when the numerical information of the jackpot random number counter C1 is sequentially updated toward the maximum value which is one boundary of the numerical range. Since the specific method for updating the information is the same, it is possible to achieve the excellent effects as described above while adopting the conventional processing method.

  In the time adjustment process, the NOP command is only read a plurality of times, so that the processing time is not easily changed. Therefore, it is possible to achieve the excellent effects as described above while suppressing fluctuations in processing time in the MPU 102. Further, it is possible to add a delay time while suppressing the influence on the progress of the game. Furthermore, since the NOP is the smallest unit instruction having the smallest number of states among the instructions executed by the MPU 102, it is easy to design the uniform processing time in the design stage of the pachinko machine 10.

  The configuration of the first pattern may be changed as follows.

  (1-1) A time adjustment process (step S504) based on the processing time T when the numerical information of the program counter is incremented by 1 without reading the NOP instruction and executing any processing for the reading. ) Is not limited to the configuration in which the time adjustment processing is set, and the time adjustment processing may be set on the basis of the time T ′ of one state corresponding to one cycle of the clock circuit.

  Specifically, when the time required to shift to the process of step S506 after executing the process of step S505 after making an affirmative determination in step S503 is s × T ′, the time adjustment process is performed. The time required needs to be set to s × T′−T. In this case, s × T ′ may not be a multiple of the processing time T in the case where the numerical information of the program counter is incremented by 1 without reading the NOP instruction and executing any processing for the reading. Conceivable. In this configuration, when only NOP is repeated in the time adjustment process, the processing time when the numerical information of the jackpot random number counter C1 is set to the minimum value and the numerical information of the jackpot random number counter C1 are one of the values. Although the processing time when sequentially updated toward the boundary cannot be made the same, the time difference between the two can be reduced.

  On the other hand, in a configuration in which s × T ′ is not a multiple of the processing time T, an instruction other than NOP is set as at least a part of the instruction set in the time adjustment process. The processing time when the numerical information of C1 is set to the minimum value may be the same as the processing time when the numerical information of the jackpot random number counter C1 is sequentially updated toward one boundary. However, this instruction other than NOP does not perform setting processing for data to be referred to by the MPU 102 when the game is advanced, that is, it affects the contents of the signal transmitted from the MPU 102. It is preferable that it is not given. For example, a process of resetting the program counter data as the current data as an instruction, a process of setting “1” to an area that is a general-purpose register and does not affect the subsequent process of the MPU 102, and the like can be considered.

  It should be noted that the processing time required for such a configuration in which an instruction other than NOP is set as described above in the first pattern to make an affirmative determination in step S503 and shift to the processing in step S506 is as described above. The present invention may be applied to a configuration that is a multiple of the processing time T.

  (1-2) In order to equalize the processing time, when a negative determination is made in step S503 and the process proceeds to the process of step S506, the first time adjustment process is executed, and an affirmative determination is made in step 503. In this case, the second time adjustment process may be executed when the process proceeds to step S506, and the delay time may be different between the first time adjustment process and the second time adjustment process.

  (1-3) After the time adjustment process makes a negative determination in step S503 and is not executed before shifting to step S506, but after step S506 and before step S205. It is good also as a structure performed by these. In this case, for example, when a negative determination is made in step S503, “1” is set in the corresponding flag, and after the process of step S507 is executed and before the process of step S203 is performed, In the middle of S203, the time adjustment process may be executed between step S203 and step S204 or between step S204 and step S205 on condition that “1” is set in the flag. Good. In this case, in consideration of the time required for setting the flag and the time required for flag determination, it is necessary to set the time to be delayed in the time adjustment process.

<Second pattern>
Next, the configuration of the second pattern serving as a countermeasure against the above fraud will be described. The lottery random number update process (step S202) has the same processing configuration as that of the first pattern.

  FIG. 14A is a flowchart showing the jackpot random number update process in the second pattern.

  First, in step S601, the numerical information held in the jackpot random number counter C1 is read into the register of the MPU 102, and in step S602, 1 is added to update the read numerical information to become the next numerical information. Thereafter, in step S603, it is determined whether or not the numerical information obtained as a result of the update in step S602 is less than or equal to the maximum value (specifically, it is determined whether or not it is less than or equal to “599”).

  If it is equal to or less than the maximum value (step S603: YES), the process proceeds to step S606 without executing the processes of steps S604 and S605. On the other hand, if it exceeds the maximum value (step S603: NO), the process proceeds to step S604, and the numerical information updated in step S602 is changed to the numerical information of the minimum value, specifically, similar to step S505. Set to “0”.

  Here, in this pattern 2, when the numerical information of the jackpot random number counter C1 is sequentially updated toward the maximum value that is one boundary of the numerical range, an affirmative determination is made in step S603. That is, as a result of reading and executing the conditional jump instruction JR, the program counter jump instruction is executed. On the other hand, when the numerical information of the jackpot random number counter C1 exceeds one boundary of the numerical range, when the numerical information is set to the minimum value that is the other boundary, a negative determination is made in step S603. . That is, as a result of reading and executing the conditional jump instruction JR, the program counter data is incremented by 1 without executing the jump instruction.

  In this case, the processing time required for making an affirmative determination in step S603 and proceeding directly to step S606 is longer than the processing time required for making a negative determination in step S603 and completing step S604. Yes. Therefore, the time adjustment process of step S605 is set after the execution of step S604 and before the execution of step S606. This time adjustment processing delays the processing time required to make a negative determination in step S603 and execute step S604 and then proceed to step S606. The processing time of the delayed result is positive in step S603. It is set to be the same or substantially the same as the processing time required for making the determination and proceeding to step S606 as it is.

  Incidentally, the processing contents of the time adjustment process are the processing time when an affirmative determination is made in step S603 and the process proceeds to step S606, and the negative determination is made in step S603 and the process of step S604 is completed. In order to fill in the time difference between the processing time required and the processing time required to move from step S605 to step S606, it may be configured to repeat the NOP instruction read and the processing not executed as in step S504. It is good also as a structure which performs the command which does not perform the setting process about the data which will be referred by MPU102, when a game is advanced except it.

  Since the processing contents of steps S606 to S609 are the same as the processing contents of steps S506 to S509, the description thereof is omitted.

  According to the configuration of the second pattern, as a result of the determination process in step S603, the program counter jump instruction is executed, so that the address when the program is read from the ROM 103 is different from the address according to the sequence up to that point. The target to be changed to the address is the side that leaves the updated numerical information in step S602. On the other hand, as a result of the determination processing in step S603, the target when the address in the case where the program is read from the ROM 103 without executing the jump instruction of the program counter is the address according to the previous order is the updated numerical value in step S602. It becomes the side which rewrites information to the minimum value. Of these two processing flows, the time adjustment processing is executed on the latter side, which is the side on which the processing time is shortened. As a result, it is possible to prevent an act of obtaining an illegal profit based on illegal reading of numerical information of the jackpot random number counter C1 while shortening the time required for each process of the jackpot random number update process. .

  Furthermore, according to this configuration, by using the processing time required to execute the jump instruction of the program counter, the processing time when the numerical information of the jackpot random number counter C1 is set to the minimum value, and the numerical information are Since the time difference from the processing time when sequentially updating is reduced, the number of NOP repetitions set for the time adjustment processing can be reduced accordingly. Therefore, it is possible to prevent such illegal activities while reducing the program capacity.

  The configuration of the second pattern may be changed as follows.

  (2-1) After making a positive determination in step S603 and executing a jump instruction of the program counter, the processing time required for shifting to step S606 is determined negative in step S603, and the program counter If it is shorter than the processing time required to move to step S606 after executing step S604 without executing the jump instruction, an affirmative determination is made in step S603 as shown in FIG. The time adjustment processing in step S605 may be executed on the destination side where the counter jump instruction has been executed, and then the program counter jump instruction may be executed to move to step S606. Even in this case, while attempting to shorten the time required for each process of the big hit random number update process, the act of trying to obtain an illegal profit based on illegal reading of the numerical information of the big hit random number counter C1 is prevented. Is possible.

  (2-2) Affirmative determination is made in step S603, and the processing time required for proceeding to step S606 as it is after executing the jump instruction of the program counter makes a negative determination in step S603. In a configuration that is the same as or substantially the same as the processing time required when the process proceeds to step S606 after executing step S604 without executing the jump instruction, the time adjustment process in step S605 may not be executed. .

  (2-3) A configuration similar to (1-2) above may be applied to the configuration of the second pattern, and a configuration similar to (1-3) above may be applied to the configuration of the second pattern. You may apply to.

<Third pattern>
Next, the configuration of the third pattern serving as a countermeasure against the above fraud will be described. The lottery random number update process (step S202) has the same processing configuration as that of the first pattern.

  FIG. 15 is a flowchart showing the big hit random number update process in the third pattern.

  First, in step S701, the numerical information held in the jackpot random number counter C1 is read into the register of the MPU 102, and in step S702, 1 is added to update the read numerical information to become the next numerical information. Thereafter, in step S703, it is determined whether or not the numerical information obtained as a result of the update in step S702 exceeds the maximum value (specifically “599”) of the jackpot random number counter C1 (specifically “ It is determined whether or not “600” or more).

  If the maximum value is not exceeded (step S703: NO), the process proceeds to step S706 as it is. In this case, the program counter jump instruction is not executed, and the program counter data is incremented by 1, and the process proceeds to step S706.

  On the other hand, if the maximum value is exceeded (step S703: YES), the numerical information updated in step S702 in step S704 is set to the numerical information of the minimum value, specifically “0”. Then, after executing the time adjustment process in step S705, the process proceeds to step S706. The contents of this time adjustment process will be described later. Incidentally, the program counter jump instruction is executed when the process proceeds to step S704 and the process proceeds to step S706.

  In step S706, it is determined whether or not the numerical information read by the MPU 102 is the same as the numerical information that has become the initial value in the current update round of the big hit random number counter C1. Specifically, the information on the initial value in the current update cycle stored in the RWM 104 is read, and the numerical information after the processing in step S702 or the numerical information after the processing in step S704 is the same as the initial value information. It is determined whether or not.

  If a negative determination is made in step S706, the process proceeds to step S707. In this case, the program counter jump instruction is not executed, and the program counter data is incremented by 1, and the process proceeds to step S707. In step S707, the numerical value information after processing in step S702 or the numerical information after processing in step S704 is set by overwriting the jackpot random number counter C1. Thereafter, the big hit random number update process is terminated.

  On the other hand, if a positive determination is made in step S706, the process proceeds to step S708. In this case, when the jump instruction of the program counter is executed, the process proceeds to step S708. In step S708, the current numerical information held in the first initial value counter CN1 is read, and in subsequent step S709, the numerical information is converted into numerical information after processing in step S702 or numerical information after processing in step S705. In addition to overwriting, an area for storing the initial value of the update cycle in the RWM 104 is overwritten. Thereafter, in step S707, the numerical value information after the processing in step S709 is set by overwriting the big hit random number counter C1, and then the big hit random number update process is terminated.

  Here, in the time adjustment processing in step S705, the numerical information read from the jackpot random number counter C1 is updated by one according to the update order, and numerical information that exceeds one boundary of the numerical range is set as the other boundary. In other words, the processing time required for setting the numerical information of the jackpot random number counter C1 to the minimum value “0” is the result of updating the numerical information read from the jackpot random number counter C1 by one according to the update order. The processing time of the jackpot random number update process in the former case is shorter than the processing time required when setting the initial value of the new update loop in the big hit random number counter C1 when the initial value in the update round is set to This is a process for approaching the processing time of the big hit random number update process in the latter case. More specifically, this is a process for making the processing time of the jackpot random number update process in the former case the same or substantially the same as the processing time of the jackpot random number update process in the latter case.

  Incidentally, the processing contents of the time adjustment processing are the processing time required to make an affirmative determination in step S703 and proceed to step S704, the processing time required to complete the processing in step S704, and after completion of step S705. In step S703, the sum of the processing time required to move to step S706 and the processing time required to make a negative determination in step S706 and move to step S707 (hereinafter also referred to as first time) Processing time required to make a negative determination and shift to step S706, processing time required to make an affirmative determination in step S706 and shift to step S708, processing time required to complete the process of step S708, step The processing time required to complete the process of S709 and after the completion of step S709 As in step S504, the NOP instruction is read and the process is not executed so as to fill the time difference with the sum of the processing times required to move to step S707 (hereinafter also referred to as second time). A configuration other than NOP may be used, and a command that does not execute a setting process for data to be referred to by the MPU 102 when the game is advanced may be executed.

  According to the configuration of the third pattern, the processing time of the jackpot random number update process when the numerical information of the jackpot random number counter C1 is set to the minimum value, and the numerical value information of the jackpot random number counter C1 as the initial value of the new update cycle The processing time of the jackpot random number update process when set to “1” is difficult to identify from the outside of the MPU 102 or cannot be identified. Therefore, even if the processing time required for step S201 to step S205 is illegally read using the illegal device A, it is difficult to specify or specify that the numerical information of the jackpot random number counter C1 has become the initial value. It becomes impossible. Therefore, even if an illegal profit is obtained based on illegal reading of numerical information of the jackpot random number counter C1, it can be prevented.

  Further, according to this configuration, the processing time of the big hit random number update processing when the numerical information of the big hit random number counter C1 is sequentially updated toward one boundary of the numerical range is longer than that in the conventional configuration. It is possible to prevent the illegal acts as described above without making them.

  The configuration of the third pattern may be changed as follows.

  (3-1) When the first time is longer than the second time, a time adjustment process is performed when an initial value of a new update cycle is set as numerical information of the jackpot random number counter C1. May be executed.

  (3-2) In step S706, it is determined whether or not the numerical information is different from the current initial value. If a negative determination is made in step S706, that is, as a result of the determination process in step S706, the program counter In the configuration in which the process of step S708 and step S709 is executed when the jump instruction is not executed and the program counter data is incremented by 1, the second time corresponding thereto is the first time and It can be the same or substantially the same. In this case, the time adjustment process in step S705 may not be executed.

  (3-3) The same configuration as the above (1-2) may be applied to the configuration of the third pattern, and the same configuration as the above (1-3) is configured of the third pattern. You may apply to.

<Fourth pattern>
Next, the structure of the 4th pattern used as the countermeasure against the said fraud is demonstrated.

  FIG. 16 is a flowchart showing lottery random number update processing in the fourth pattern.

  First, in step S801, a jackpot random number update process for periodically updating the numerical information of the jackpot random number counter C1 is executed. In this case, the jackpot random number update process has a processing configuration in which the time adjustment process in step S504 is not executed in the jackpot random number update process (FIG. 13A) in the first pattern. That is, the processing time of step S201 to step S205 when the numerical information of the jackpot random number counter C1 is set to the minimum value, the numerical information of the jackpot random number counter C1 is sequentially updated, or the numerical information of the jackpot random number counter C1 is The processing for making the processing time the same as or substantially the same as the processing time of steps S201 to S205 in the case where the initial value is set is not executed.

  Instead, in steps S802 to S804, processing for making the processing times of steps S201 to S205 irregular is executed. Specifically, first, in step S802, information on the number of repetitions is acquired and stored in the register of the MPU 102.

  The information on the number of repetitions is stored in a repetition number counter provided in the RWM 104, and this repetition number counter is a loop counter that loops within a predetermined numerical range. In this case, the minimum value in the numerical range of the repetition counter is “0”, but the minimum value may be 1 or more. By setting the minimum value to 1 or more, the delay time is surely set in the delay processing in steps S802 to S804.

  The numerical information of the repetition number counter is updated in the remaining process of steps S110 to S115 in the main process (FIG. 8). In this case, as described above, since the remaining processing is performed irregularly, the information on the number of repetitions is irregular.

  In order to make the information on the number of repetitions irregular, it is not limited to the configuration in which the repetition number counter is used and the numerical information is updated by the residual process as described above. Alternatively, the information on the number of repetitions may be sequentially updated by a circuit that operates separately, and the information on the number of repetitions held at that time may be provided to the control unit of the MPU 102 at the timing of step S802. This circuit may be implemented as a single chip as the MPU 102 or may be implemented as a separate chip from the MPU 102. Further, it may be configured to sequentially update the information on the number of repetitions using a refresh register.

  In the subsequent step S803, the obtained information on the number of repetitions is updated so as to be decremented by 1. In step S804, it is determined whether or not the information on the number of repetitions after the update is “0”. If a negative determination is made in step S804, the processes of step S803 and step S804 are executed again. On the other hand, if an affirmative determination is made in step S804, the process of steps S805 to S807 is executed. The lottery random number update process is terminated. Each processing content in steps S805 to S807 is the same as each processing content in steps S402 to S404.

  As described above, the irregularity delay processing is executed in steps S802 to S804 by using the information on the number of repetitions, and the timing when the numerical information of the big hit random number counter C1 is set to the minimum value is incorrect. Even if device A tries to identify the device by grasping the processing time of steps S201 to S205, it is difficult to do so.

  Here, in order to make it difficult to specify the timing at which the numerical information of the jackpot random number counter C1 is set to the minimum value based on executing the irregular delay processing as described above, it is selected by the delay processing. Among multiple types of delay time, the processing time of the big hit random number update process when the numerical information of the big hit random number counter C1 is set to the minimum value, and the case where the numerical value information of the big hit random number counter C1 is set to the minimum value It is preferable that a delay time that is equal to or greater than the time difference from the processing time of the jackpot random number update process when set in a different manner is included.

  More preferably, the processing time of the jackpot random number update processing when the numerical information of the jackpot random number counter C1 is set to the minimum value among the plurality of types of delay times selected in the delay processing, and the jackpot random number counter C1 This is a configuration that includes a delay time that is equal to or greater than the time difference from the processing time of the jackpot random number update process when the numerical information is sequentially updated toward the maximum value.

  Also, instead of or in addition to the configuration, the processing time of the big hit random number update process when the numerical information of the big hit random number counter C1 is set to the minimum value among a plurality of types of delay times selected in the delay process. And a delay time that is equal to or greater than a time difference from the processing time of the big hit random number update process when the numerical information of the big hit random number counter C1 is set to an initial value. Thereby, even if the unauthorized device A illegally reads the processing time of steps S201 to S205, either the setting of the minimum value of the big hit random number counter C1 or the setting of the initial value of the big hit random number counter C1 is executed. It becomes impossible to specify.

  The configuration of the fourth pattern may be changed as follows.

  (4-1) The irregular delay process shown in steps S802 to S804 is not necessarily performed immediately after the process of step S801, and may be performed within the range of steps S201 to S205. Is optional. For example, the irregular delay process may be executed at the start of the lottery random number update process, and the irregular delay process may be executed at the end of the lottery random number update process.

<Fifth pattern>
Next, the configuration of the fifth pattern serving as a countermeasure against the above fraud will be described. The lottery random number update process (step S202) has the same processing configuration as that of the first pattern.

  FIG. 17A is a flowchart showing a jackpot random number update process in the fifth pattern, FIG. 17B is a flowchart showing a reach random number update process in the fifth pattern, and FIG. It is a flowchart which shows the electric role random number update process in the pattern.

  As shown in FIG. 17A, in the jackpot random number update process of this pattern, a processing configuration in which the time adjustment process in step S504 is not executed in the jackpot random number update process in the first pattern (FIG. 13A). It has become. That is, in steps S901 to S903, processing similar to that in steps S501 to S503 is executed. In step S904, processing similar to that in step S505 is executed. In steps S905 to S908, steps S506 to S509 are performed. A similar process is executed.

  As shown in FIG. 17 (b), in the reach random number update process of this pattern, first, in step S911, the numerical information held in the reach random number counter C3 is read to the register of the MPU 102, and is read in step S912. 1 is added to update the numerical information to be the next numerical information. Thereafter, in step S913, it is determined whether or not the numerical information obtained as a result of the update in step S912 exceeds the maximum value (specifically “238”) of the reach random number counter C3 (specifically, “ 238 "or more).

  If the maximum value is not exceeded (step S913: NO), the process proceeds directly to step S914. In this case, the program counter jump instruction is not executed, and the program counter data is incremented by 1, and the process proceeds to step S914. In step S914, the numerical information after the processing in step S912 is set by overwriting the reach random number counter C3. Thereafter, the reach random number update process is terminated.

  If it exceeds the maximum value (step S913: YES), in step S915, the numerical information updated in step S912 is set to the numerical information of the minimum value, specifically “0”. In the subsequent step S916, reach side time adjustment processing is executed. The processing content of the time adjustment processing will be described later. Thereafter, in step S914, the numerical value information after the processing in step S915 is set by overwriting the reach random number counter C3, and then the reach random number update process is terminated. Incidentally, the program counter jump instruction is executed when the process proceeds to step S915 and the process proceeds to step S914.

  As shown in FIG. 17 (c), in the electric random number update process of this pattern, first, in step S921, the numerical information held in the electric random number counter C4 is read into the register of the MPU 102, and in step S922, The read numerical information is incremented by 1 to be updated to become the next numerical information. Thereafter, in step S923, it is determined whether or not the numerical value information updated in step S922 exceeds the maximum value (specifically, “250”) of the electric utility random number counter C4 (specifically, It is determined whether or not “250” or more).

  If the maximum value is not exceeded (step S923: NO), the process proceeds to step S926 as it is. In this case, the jump instruction of the program counter is not executed, and the program counter data is incremented by 1, and the process proceeds to step S926.

  If the maximum value is exceeded (step S923: YES), in step S924, the numerical information updated in step S922 is set to the numerical information of the minimum value, specifically “0”. In subsequent step S925, a time adjustment process on the electric role side is executed. The processing content of the time adjustment processing will be described later. Thereafter, the process proceeds to step S926. Incidentally, the program counter jump instruction is executed when the process proceeds to step S924 and the process proceeds to step S926.

  In step S926, it is determined whether or not the numerical information read by the MPU 102 is the same as the numerical information that has become the initial value in the current update cycle of the electronic random number counter C4. Specifically, information on the initial value in the current update cycle stored in the RWM 104 is read, and the numerical information after the processing in step S922 or the numerical information after the processing in step S925 is the same as the initial value information. It is determined whether or not.

  If a negative determination is made in step S926, in step S927, the numerical value information after the processing in step S922 or the numerical information after the processing in step S925 is set by overwriting the electronic random number counter C4. Thereafter, the big hit random number update process is terminated.

  On the other hand, if an affirmative determination is made in step S926, the current numerical information held in the third initial value counter CN3 is read in step S928, and the numerical information is processed in step S922 in step S929. Overwrite the subsequent numerical information or the numerical information after the processing in step S925, and overwrite the area for storing the initial value of the update cycle in the RWM 104. Thereafter, in step S927, the numerical value information after the processing in step S929 is set by overwriting the electric utility random number counter C4, and then the big hit random number update processing is terminated.

  The reach-side time adjustment processing in step S916 is performed in steps S201 to S205 when the numerical information of the jackpot random number counter C1 is not set to the initial value and the numerical information of the reach random number counter C3 is set to the initial value. To reach the processing time of steps S201 to S205 when the numerical information of the jackpot random number counter C1 is set to the initial value and the numerical information of the reach random number counter C3 is not set to the initial value. This is a process for delaying the processing time of the reach random number update process when the numerical information of C3 is set to the initial value. More specifically, this is processing for making the former processing time and the latter processing time the same or substantially the same.

  Further, the time adjustment process on the electric role side in step S925 is a step in the case where the numerical information of the electric random number counter C4 is set to the initial value without the numerical information of the jackpot random number counter C1 being set to the initial value. To approximate the processing time of S201 to Step S205 to the processing time of Step S201 to Step S205 when the numerical information of the jackpot random number counter C1 is set to the initial value and the numerical information of the electric random number counter C4 is not set to the initial value. Furthermore, this is a process for delaying the processing time of the electric random number update process when the numerical information of the electric random number counter C4 is set to the initial value. More specifically, this is processing for making the former processing time and the latter processing time the same or substantially the same.

  The jackpot random number counter C1 is set to 2 bytes in the RWM 104, whereas the reach random number counter C3 and the electric random number counter C4 are set to 1 byte in the RWM 104, respectively. In this case, when the numerical information of the jackpot random number counter C1, the reach random number counter C3, and the electric random number counter C4 is set to the minimum value, the “0” clear process is executed. Processing is performed in bytes, not bits. Then, the processing time for setting the jackpot random number counter C1 to the minimum value (step S904) is longer than the processing time for setting the reach random number counter C3 to the minimum value (step S915). This is longer than the processing time of the process (step S924) for setting the electric random number counter C4 to the minimum value. The same applies to the jackpot type counter C2, and since 1 byte is also set in the RWM 104 for the jackpot type counter C2, the processing time for setting the jackpot random number counter C1 to the minimum value is the jackpot type counter C2. Is longer than the processing time for setting the value to the minimum value. Therefore, by reading the processing time of step S201 to step S205 using the unauthorized device A, in the lottery random number update process (step S202), the big hit random number counter C1, the big hit type counter C2, the reach random number counter C3, and When any one of the electric random number counters C4 is set to the minimum value, it is possible to specify whether or not it is for the big hit random number counter C1.

  On the other hand, when the reach side time adjustment process (step S916) and the power side time adjustment process (step S925) are executed as described above, the lottery random number update process (step S202) is performed. Thus, only the jackpot random number counter C1 is set to the minimum value, only the reach random number counter C3 is set to the minimum value, and only the electric random number counter C4 is set to the minimum value. Even if the processing time of step S201 to step S205 is illegally read, it cannot be specified. Therefore, even if an illegal profit is obtained based on illegal reading of numerical information of the jackpot random number counter C1, it can be prevented.

  Incidentally, the specific processing content of each time adjustment process does not execute the process by reading the NOP instruction in the same manner as in step S504 so as to fill the time difference between the processing times for equalizing the processing time. It may be configured to repeat this, or may be configured to execute an instruction that does not execute a setting process for data to be referred to by the MPU 102 when the game is advanced except for the NOP.

  The configuration of the fifth pattern may be changed as follows.

  (5-1) Only one of the time adjustment process on the reach side and the time adjustment process on the power role side may be executed.

  (5-2) Also in the jackpot type update process, when the numerical information of the jackpot type counter C2 is set to the minimum value, the time adjustment process on the type side may be executed. In this case, the time adjustment processing on the type side is performed in steps S201 to S205 when the numerical information of the jackpot type counter C2 is set to the initial value without the numerical information of the jackpot random number counter C1 being set to the initial value. In order to approach the processing time of steps S201 to S205 when the numerical information of the jackpot random number counter C1 is set to the initial value and the numerical information of the jackpot type counter C2 is not set to the initial value. What is necessary is just to delay the processing time of the big hit type update process when the numerical information of C2 is set to the initial value. More specifically, as the process for making the former process time and the latter process time the same or substantially the same, the time adjustment process on the type side may be set. When the time adjustment processing on the type side is executed in this way, the time adjustment processing on the reach side and the time adjustment processing on the power role side may not be executed, but the numerical information of the jackpot random number counter C1 is minimized. In order to make it difficult to specify the timing set in the value, it is preferable that either one of the time adjustment process on the reach side and the time adjustment process on the power side is executed. Both of these processes are executed. It is more preferable to adopt a configuration.

  (5-3) By making the number of bytes allocated as the jackpot random number counter C1 in the RWM 104 equal to the number of bytes allocated as the reach random number counter C3 in the RWM 104, the time required for the processing in step S904 and the step S915 The time required for this processing may be the same or substantially the same. In this case, whether the jackpot random number counter C1 is set to the minimum value or only the reach random number counter C3 is set to the minimum value without executing the process of step S916. Cannot be specified even if the processing time of steps S201 to S205 is illegally read. Note that this configuration may be applied to the jackpot type counter C2 or the electric random number counter C4.

  (5-4) In place of the configuration for executing the process of step S916, in step S915, the process of setting the reach random number counter C3 to the minimum value, that is, the process of clearing the corresponding 1-byte area in the RWM 104 twice. It may be configured to execute. In this case, when the reach random number counter C3 is set to the minimum value, the number of bytes to be cleared is the same as the number of bytes to be cleared when the big hit random number counter C1 is set to the minimum value. Accordingly, whether the jackpot random number counter C1 is set to the minimum value or only the reach random number counter C3 is set to the minimum value without executing the process of step S916. Even if the processing time of step S201 to step S205 is illegally read, it cannot be specified. Note that this configuration may be applied to the jackpot type counter C2 or the electric random number counter C4.

<Sixth pattern>
Next, the configuration of the sixth pattern serving as a countermeasure against the above fraud will be described.

  In the sixth pattern, the processing configuration of the timer interrupt processing is different from the processing configuration of the timer interrupt processing (FIG. 9) already described. FIG. 18 is a flowchart showing timer interrupt processing in this pattern.

  As shown in FIG. 18, in this timer interrupt process, first, a lottery random number update process is executed in step S1001, and then a power failure information storage process is executed in step S1002. Thereafter, in steps S1003 to S1023, processing similar to that in steps S203 to S223 in the timer interrupt processing (FIG. 9) is executed.

  That is, in this pattern, the lottery random number update process is not included between the power failure information storage process (step S1002) and the game stop determination process (step S1005). Therefore, even if the processing time between these processes is read illegally, the timing at which the numerical information of the jackpot random number counter C1 is set to the minimum value cannot be specified. Also, the lottery random number update process is not included in the process for the MPU 102 to input / output through the input / output port 102a within the range of one processing time of the timer interrupt process. Therefore, the processing time between the process related to one input / output and the process related to the subsequent input / output is illegal except between step S1002 and step S1005 within the range of one processing time of the timer interrupt process. Even when read, the timing at which the numerical information of the jackpot random number counter C1 is set to the minimum value cannot be specified.

  However, if the processing time between the processing related to one input / output in one processing time of the timer interrupt processing and the processing related to input / output that is the same as or different from that in the next processing time is illegally read, the processing The lottery random number update process is included in the time. On the other hand, the lottery random number update process is set to be executed at a timing before the process related to the first input / output in the timer interrupt process. That is, after the residual process in steps S110 to S115 of the main process (FIG. 8), before the process related to input / output (process related to at least one of input and output) executed first thereafter. The lottery random number update process is executed.

  As described above, the remaining process is a non-periodic process in which the presence or absence of execution and the number of executions between two timer interrupt processes fluctuate irregularly according to the process completion time of each timer interrupt process. The processing time from the completion of the timer interrupt processing of the first time to the execution of the processing related to the first input / output in the timer interrupt processing of the next processing time varies irregularly. Then, even if the processing time between the processing related to one input / output in one processing time of the timer interrupt processing and the processing related to input / output that is the same as or different from that in the next processing time is read illegally, It becomes difficult to specify whether or not the numerical information of the big hit random number counter C1 is set to the minimum value in the lottery random number update process, or cannot be specified.

  In this configuration, the timing at which the jackpot random number counter C1 is set to the initial value, the timing at which the jackpot type counter C2 is set to the minimum value, the timing at which the jackpot type counter C2 is set to the initial value, the reach random number counter Regarding the timing when C3 is set to the minimum value, the timing when the electronic random number counter C4 is set to the minimum value, and the timing when the electronic random number counter C4 is set to the initial value, the processing time is incorrect as described above. It is difficult to specify or cannot be specified only by reading.

  Incidentally, the lottery random number update process in this pattern is the same as that in the first pattern. In addition, the time adjustment process as described in each of the above patterns including the big hit random number update process is not executed.

  Note that the configuration of the sixth pattern may be changed as follows.

  (6-1) In a configuration in which a lottery random number update process (that is, a big hit random number update process) is included between the residual process and the process related to input / output that is first executed thereafter, the lottery random number update It is not essential that the process is executed at the first timing of the timer interrupt process, and a process related to input / output, that is, a signal for selecting an input driver or a signal for selecting an output driver is output from the MPU 102. Random number random number update process on condition that it is not a process, a process in which a command is not output from MPU 102 to another control device, and a process in which a signal is not output from MPU 102 to the management computer of the game hall Another process may be performed before the other. For example, the process of reading predetermined data from the ROM 103 may be executed before the lottery random number update process.

  (6-2) In the timer interruption process shown in FIG. 19, first, in step S1101, a power failure information storage process is executed in the same manner as in step S201. Thereafter, in steps S1102 to S1120, processing similar to that in steps S203 to S221 is executed. Then, after the lottery random number update process is executed in step S1121, an interrupt end declaration is set in step S1122, and interrupt permission is set in step S1123. Thereafter, the timer interrupt process is terminated. In the case of this processing configuration, in the configuration in which the remaining processing can be executed without executing the processing related to the other input / output after the processing related to the predetermined input / output (step S1119) is executed, A lottery random number update process is executed between the process and the remaining process. As a result, similarly to the above pattern 6, the processing time between the processing related to one input / output in one processing time of the timer interrupt processing and the processing related to input / output that is the same as or different from that in the next processing time. Even if it is illegally read, it becomes difficult or impossible to specify whether or not the numerical information of the big hit random number counter C1 is set to the minimum value in the lottery random number update process.

  (6-3) As shown in FIG. 20 and FIG. 21, a game is given to each of a normal process in which the first process is periodically executed and a timer interrupt process in which the first process is also periodically executed. In a processing configuration in which processing necessary for progressing is set in a distributed manner, the same countermeasure as in the sixth pattern may be adopted.

  Specifically, the normal process is executed after the process of step S109 in the main process (FIG. 8) is executed. Then, as shown in FIG. 20, the same processing as step S207 is executed in step S1201, the same processing as steps S203 to S204 is executed in steps S1202 to S1203, and steps S1204 to S120 are executed. In S1213, processing similar to that in steps S212 to S221 is executed. Thereafter, in step S1214, it is determined whether or not “1” is set in the power failure flag. The power failure flag is set to “1” when the occurrence of a power failure is specified in the power failure information storage process in step S1302 in the timer interrupt process (FIG. 21).

  If “1” is not set in the power failure flag, it is determined in step S1215 whether or not it is the execution timing of the next normal process, that is, a predetermined time (specifically 4 msec) from the start of the previous normal process. It is determined whether or not it has elapsed. Then, the remaining processes in steps S1216 to S1219 are repeatedly executed until the normal process start timing is reached. The processing contents in steps S1216 to S1219 are the same as those in steps S110 to S115.

  On the other hand, if it is determined in step S1214 that “1” is set in the power failure flag, the power failure processing after step S1220 is executed. That is, in step S1220, the generation of timer interrupt processing is prohibited, and then the RWM determination value is calculated and stored in step S1221, and after the access of the RWM 104 is prohibited in step S1222, the power supply is completely shut down and processed. Continue infinite loop until no longer runs.

  In the timer interruption process, as shown in FIG. 21, a lottery random number update process is first executed in step S1301. The contents of this process are the same as in step S1001. Thereafter, processing similar to that in step S201 is executed in step S1302, processing similar to that in step S205 is executed in step S1303, and processing similar to that in steps S208 to S211 is performed in steps S1304 to S1307. After executing, this timer interrupt processing ends.

  With the above processing configuration, in the configuration in which the processing for controlling the progress of the game is distributed to each of the normal processing and the timer interrupt processing, it is executed after the remaining processing and first after that. The lottery random number update process (big hit random number update process) is executed before the process related to input / output (process related to at least one of input and output). As a result, even if the processing time between the processing related to one input / output in one processing time of the timer interrupt processing and the processing related to input / output same as or different from that in the next processing time is read illegally In the lottery random number update process, it becomes difficult or impossible to specify whether or not the numerical information of the big hit random number counter C1 is set to the minimum value.

  The lottery random number update process may be executed after the last input / output process in the timer interrupt process (FIG. 21).

  (6-4) In the big hit random number update processing, the processing when the numerical information of the big hit random number counter C1 is sequentially updated toward the maximum value and the minimum when the numerical information of the big hit random number counter C1 exceeds the maximum value The process for setting the value may be set separately, and a process different from the process related to the update of the jackpot random number counter C1 may exist between the processes. In this case, at least the process for setting the minimum value is after the residual process in steps S110 to S115, and the process related to input / output that is executed first after that (related to at least one of input and output) It is preferable to be executed before (processing). Alternatively, in the configuration in which the remaining process can be executed without executing the process related to another input / output after the process related to the predetermined input / output is executed, the process related to the predetermined input / output and the remaining process In the meantime, it is preferable that at least the process for setting the minimum value is executed.

  As described above, by adopting any one of the first pattern to the sixth pattern, it is possible to use the unauthorized device A to perform one input / output after the process related to one input / output in the MPU 102. Even if the processing time up to the processing related to this is illegally read, it becomes difficult to specify the timing when the numerical information of the jackpot random number counter C1 becomes the minimum value, or it becomes impossible to specify.

  Further, if any of the first pattern to the sixth pattern is used, the numerical information of the jackpot random number counter C1 is not directly manipulated in order to suppress the fraud. Since only delay or irregularization is performed, inconvenience is less likely to occur with respect to the determination of success / failure using the numerical information of the jackpot random number counter C1.

  In this case, the pachinko machine 10 has any one of the first to sixth patterns, but may have a plurality of patterns at the same time. For example, any of the configuration according to the first pattern, the configuration according to the second pattern, the configuration according to the third pattern, the configuration according to the fifth pattern, and the configuration according to the fourth pattern And at least one of the configurations according to the sixth pattern may be included at the same time.

  In addition, it is not limited to the description content of embodiment mentioned above, A various deformation | transformation improvement is possible within the range which does not deviate from the meaning of this invention. For example, you may change as follows. Incidentally, the configuration of another embodiment described below may be applied individually or in combination to the configuration of the above embodiment.

  Instead of the configurations of the first to sixth patterns, a CPU or dedicated circuit for updating the numerical information of the jackpot random number counter C1 is provided separately from the control unit of the MPU 102, and the numerical value of the jackpot random number counter C1 The configuration may be such that the updating of information, the setting of the minimum value, and the setting of the initial value when starting the updating cycle are executed independently of the control unit of the MPU 102. In the case where the control unit of the MPU 102 executes the determination process using the numerical information of the jackpot random number counter C1, the numerical information at that time may be acquired from the separate control unit. In this configuration, the time required for providing numerical information from the separate control unit to the MPU 102 is constant (same or substantially the same between different provision timings), so that the predetermined device is used by using the unauthorized device A. Even if the processing time between these processes is acquired, it is possible to make it difficult or impossible to specify the timing at which the numerical information of the jackpot random number counter C1 becomes the minimum value.

  Further, in this configuration, the separate control unit may be provided as a separate chip from the control unit of the MPU 102, but the numerical value after the update of the separate control unit by illegally accessing both communication paths. In order to prevent an act of illegally acquiring information, it is preferable that the separate control unit and the control unit of the MPU 102 are integrated into one chip.

  Hereinafter, the configuration using the separate control unit as described above is also referred to as a seventh pattern.

  -Instead of the configurations of the first to seventh patterns described above, a configuration that directly suppresses the act of specifying the timing at which processing related to input / output is executed in the MPU 102 by illegal acquisition of signals may be adopted. Good. Specifically, a fourth signal path LN4 (see FIG. 11) that electrically connects the MPU 102 and the first port driver 101a, and a fifth signal that electrically connects the MPU 102 and the second port driver 101b. The signal corresponding to the signal is transmitted to the path LN5 in spite of the fact that the process of receiving the signal is not actually executed in the MPU 102. Further, when the dummy signal is transmitted, the MPU 102 receives the signal reception result. It is good also as a structure which does not confirm or invalidates. In this case, the signal may be transmitted periodically or irregularly. Further, the signal may be transmitted from a dedicated element provided on the path between the MPU 102 and the port drivers 101a and 101b, or may be transmitted by the MPU 102 itself.

  In addition, the target for transmitting the dummy signal as described above is not limited to one or both of the signal path LN4 and the signal path LN5, and in addition to or instead of the signal path LN1, the signal path LN2, and A configuration may be adopted in which at least one of the signal paths LN3 is a target. For example, when it is attempted to read the presence / absence of execution of processing related to input / output illegally through the signal path LN1 and the signal path LN2, it is conceivable to read a change in current flowing through the signal paths LN1 and LN2. Therefore, an element may be provided that periodically or irregularly generates changes in the currents flowing through the signal paths LN1 and LN2 at timings different from when the MPU 102 actually receives signals. .

  Hereinafter, the configuration that directly suppresses unauthorized acquisition of signals as described above is also referred to as an eighth pattern.

  It is assumed that an illegal act using the unauthorized device A is performed by illegally reading a processing time between two processes related to signal output from the MPU 102 to the external device. Therefore, any one of the first to eighth patterns may be applied to such a configuration. Specifically, the processing time between two processes related to command output from the MPU 102 to the other control devices (sound light control device 82, payout control device 97, power supply and launch control device 98) is determined by the unauthorized device A. It is assumed that it is read illegally. In this case, for example, when the jackpot random number update process or lottery random number update process is executed between the process related to one command output and the process related to the next command output, the jackpot random number update process or lottery Any one of the first to eighth patterns may be adopted for the random number update process.

  In order to make it difficult or impossible to specify the timing at which the numerical information of the jackpot random number counter C1 becomes the minimum value, the jackpot random number counter is not adopted, but the configuration of any of the first to eighth patterns is adopted. In order to make it difficult or impossible to specify the timing at which the numerical information of C1 is set as the initial value of a new update cycle, the configuration of any of the first to eighth patterns may be adopted.

  For example, when the first pattern or the second pattern is adopted, the processing time when the numerical information of the jackpot random number counter C1 is set to the initial value and the numerical information of the jackpot random number counter C1 are the numerical values. The processing configuration such as the time adjustment processing is set as in the first pattern or the second pattern so that the processing time in the case of sequentially updating toward one boundary of the range is the same or substantially the same. do it.

  When the fifth pattern is adopted, the processing time when the numerical information of the jackpot random number counter C1 is set to the initial value and the numerical value of at least one of the jackpot type counter C2 and the electric random number counter C4 are used. The processing configuration such as the time adjustment processing may be set like the first pattern or the second pattern so that the processing time when the information is set to the initial value is the same or substantially the same. .

  In addition to adopting the configuration of any one of the first to eighth patterns in order to make it difficult or impossible to specify the timing at which the numerical information of the jackpot random number counter C1 becomes the minimum value or the initial value. Alternatively, the timing at which the numerical information becomes the minimum value or the initial value is specified for at least one of the counter used in other privilege grant processing, specifically, the jackpot type counter C2 and the electric random number counter C4. In order to make it difficult or unspecified, any one of the first to eighth patterns may be adopted.

  The jackpot random number counter C1 is configured such that when the numerical information is sequentially updated toward one boundary of the numerical value range, the numerical information is incremented by 1, but the numerical information is sequentially updated. The numerical information may be subtracted by one. In this case, the maximum value is set when the numerical information is subtracted by 1 and falls below the minimum value. Even in this configuration, when the numerical information that is below the minimum value is set to the maximum value, the processing time becomes longer than when the numerical information is sequentially updated. It is preferable to adopt any configuration of patterns.

  The jackpot random number counter C1 is not limited to a configuration in which the numerical value changes by 1 when the numerical information is sequentially updated. For example, “2” → “4” → “6” → “8” → It is good also as a structure which changes by 2 like this. Moreover, it is good also as a structure which changes every 2 like "1"-> "3"-> "5"-> "7"-> .... Further, the change amount of the numerical value is not limited to “1” or “2”, and may be configured to change by another predetermined amount such as “3” or “4”. Even in these cases, if one boundary is exceeded, it is necessary to set numerical information corresponding to the other boundary, and the processing time for this setting is sequentially updated as described above. It may be different from the processing time. Therefore, even in this configuration, it is preferable to employ any one of the first to eighth patterns.

  A configuration in which the setting of the numerical value range from one boundary side to the other boundary side is performed a plurality of times in one update round of the big hit random number counter C1. For example, first, numerical information is sequentially updated in the order of “2” → “4” → “6” → “8” →... When the maximum value is exceeded, “1” is set to the minimum value side. After that, the numerical information is sequentially updated again in the order of “1” → “3” → “5” → “7” →. And when all the numerical information is set once, it is good also as a structure which sets a new initial value and starts a new update round. Even in this case, if one boundary is exceeded, it is necessary to set numerical information corresponding to the other boundary, and the processing time when the processing time for this setting is sequentially updated as described above It may be different from time. Therefore, even in this configuration, it is preferable to employ any one of the first to eighth patterns.

  The jackpot random number counter C1 is not limited to a configuration in which the numerical value is changed by the same numerical value when the numerical information is sequentially updated, and the numerical value information is sequentially updated at a predetermined update timing when the numerical information is sequentially updated. A configuration may be adopted in which one predetermined number changes, while at another update timing, a second predetermined number different from the first predetermined number changes. However, the numerical information is sequentially updated according to a predetermined order. Even in this case, when one boundary is exceeded, it is necessary to set numerical information corresponding to the other boundary, and processing when the processing time for this setting is sequentially updated as described above It may be different from time. Therefore, even in this configuration, it is preferable to employ any one of the first to eighth patterns.

  -Other types of pachinko machines different from the above embodiment, such as pachinko machines that release the electric game a predetermined number of times when a game ball enters a specific area of a special device, or a game ball enters a specific area of a special device The present invention can also be applied to a pachinko machine that generates a big hit when a right is generated, a pachinko machine equipped with other objects, an arrangement ball machine, a sparrow ball, and other gaming machines.

  Also, a non-ball-type gaming machine, for example, a plurality of reels with a plurality of types of symbols attached in the circumferential direction, starts rotation of the reel by inserting a medal and operating a start lever, and a stop switch is operated. If a specific symbol or a combination of specific symbols is established on the effective line visible from the display window after the reel has stopped after a predetermined time has passed, a privilege such as paying out medals is given to the player The present invention can also be applied to a slot machine.

  In addition, the gaming machine main body supported by the outer frame so as to be openable and closable is provided with a storage unit and a capture device, and the start lever is operated after a predetermined number of game balls stored in the storage unit are captured by the capture device. Thus, the present invention can also be applied to a gaming machine in which a pachinko machine and a slot machine are started to start rotating a reel.

  When applied to a slot machine or when applied to a gaming machine in which a pachinko machine and a slot machine are fused, with regard to updating the numerical information of the lottery counter used for executing the winning / failing lottery of the role in the main control device, Any configuration of the first pattern to the eighth pattern may be adopted, and a privilege (specifically, to the player) in the sub-control device that controls the display device based on an instruction from the main control device. Even if the configuration of any one of the first pattern to the eighth pattern is adopted for updating the numerical information of the lottery counter used for executing the lottery that affects the grant rate of the medal payout) Good.

<Second Embodiment>
The act of illegally reading that the numerical information storage means such as the jackpot random number counter C1 is the predetermined numerical information is an unauthorized device A for each of the fourth signal path LN4 and the fifth signal path LN5 (see FIG. 11). In addition to the action based on the electrical connection of the two, the electromagnetic wave noise accompanying the transmission of the signal through the fourth signal path LN4 and the fifth signal path LN5 (that is, accompanying a predetermined current flowing through the specific electrical path) An act based on picking up (electromagnetic noise) is assumed (hereinafter, an illegal act by the act is also referred to as a specific illegal act).

  The specific fraud will be described in detail. First, a fraudulent jig provided with a detection unit for detecting electromagnetic noise at the tip of a long member such as a cell is provided on the back side of the pachinko machine 10. insert. This insertion is performed by pushing the gaming machine main body 12 upward to create a slight gap between the lower end portion of the gaming machine main body 12 and the lower frame portion of the outer frame 11, and using the gap. Is called. Then, the inserted incorrect jig is operated so that the tip portion reaches the back side of the pachinko machine 10, and reaches the main controller 81 side present above the lower end of the gaming machine main body 12. Operate as follows. After the leading end portion of the fraudulent jig is guided to the main control device 81 side, the leading end portion of the fraudulent jig is disposed at a position behind the pachinko machine 10 with respect to the area where the MPU 102 is provided in the main control device 81. .

  In this state, by detecting electromagnetic wave noise when a signal is output through the fourth signal path LN4 with an unauthorized jig, the power failure information storage process (step S201) in the timer interrupt process (FIG. 9) is performed. The game stop determination process in the timer interrupt process (FIG. 9) can be performed by illegally grasping the execution timing and detecting the electromagnetic wave noise when the signal is output through the fifth signal path LN5 by the illegal jig. The execution timing of (step S205) can be grasped illegally. Then, by reading the time between these processes, it is possible to grasp the time required for the lottery random number update process (step S202) in the timer interrupt process (FIG. 9).

  The specific fraud can be suppressed by the fraud countermeasure configuration shown in the first embodiment. However, in the present embodiment, the configuration of the countermeasure against fraud is different from that in the first embodiment. Hereinafter, the configuration of the fraud countermeasure will be described. In addition, about the same structure as the said 1st Embodiment, while attaching | subjecting the same number as the case of the said 1st Embodiment, the description is abbreviate | omitted fundamentally.

  FIG. 22 is a rear view of the gaming machine main body 12 in the present embodiment. FIG. 23 (a) is a perspective view of the gaming machine main body 12 as seen from the back side, and FIG. 23 (b) is an exploded perspective view showing a state in which the anti-fraud component is removed in the state of FIG. 23 (a). FIG. 23A and 23B show a state where the front door frame 14 is removed.

  As shown in FIGS. 22, 23 (a) and 23 (b), the main control device 81 is provided on the back side of the inner frame 13 (game board 24), as in the first embodiment. . In this case, the main control device 81 has a substantially rectangular parallelepiped box shape having a rectangular front surface and back surface, and the surface of the main control device 81 faces the back of the pachinko machine 10 and has the long side portion of the rectangular shape. It is fixed to the inner frame 13 so that the direction is the horizontal direction. Further, the position at which the main control device 81 is disposed is below the center in the vertical direction of the pachinko machine 10 and above the lower end of the gaming machine main body 12.

  The main control device 81 includes a main control board 101 and a board box 83 that accommodates the main control board 101, as in the first embodiment. The board box 83 is formed to be transparent, specifically colorless and transparent so that the main control board 101 can be seen from the outside of the board box 83. As shown in FIG. 22, the main control board 101 is equipped with an MPU 102 and electrically connects the main control board 101 to the payout control device 97, the power source and launch control device 98, and various sensors. Connectors 121a to 121e are provided as connection portions. These connectors 121a to 121e are exposed to the outside of the main control device 81 through openings 122a to 122e formed in portions of the board box 83 that constitute the surface of the main control device 81. Further, the main control device 81 is provided with an initialization switch 123 that is operated when the RWM 104 is initialized. The initialization switch 123 also constitutes the surface of the main control device 81 in the substrate box 83. It is exposed to the outside of the main control device 81 through the opening 124 formed in the portion to be operated.

  The substrate box 83 is provided with trace means for leaving a trace when the internal space is opened. As one of the trace means, a seal seal 125 is attached so as to straddle a plurality of case bodies constituting the substrate box 83. In order to open the internal space of the substrate box 83, it is necessary to separate the plurality of case bodies, and it is necessary to peel off the sealing seal 125 for the separation. When the seal seal 125 is peeled off from the pasted portion, the adhesive layer of the seal seal 125 remains on the substrate box 83 side, and the trace remains.

  In addition, the seal seal 125 is provided with an IC tag that transmits a response wave including identification information in response to a ringing wave transmitted from a reader device held by the manager of the game hall. The IC tag is provided such that when the seal seal 125 is peeled off, the antenna of the IC tag is cut and the response wave cannot be transmitted. Therefore, it is possible to easily confirm whether or not the board box 83 is illegally opened by transmitting a calling wave from the reader device in a state where the gaming machine main body 12 is rotated forward with respect to the outer frame 11. It becomes possible. The seal seal 125 is provided on one short side of the substrate box 83 and is present at one end in the horizontal direction of the main controller 81 in a state where the main controller 81 is mounted on the pachinko machine 10. doing.

  A back pack unit 15 is rotatably supported on the back side of the inner frame 13 on which the main control device 81 is mounted. The back pack unit 15 includes a back pack 91 that covers the back side of the inner frame 13, and a protective cover portion 94 is integrally formed on the back pack 91 so as to bulge behind the pachinko machine 10. The protective cover portion 94 covers the game board 24 of the inner frame 13 from the rear in the closed state of the back pack unit 15. However, as shown in FIG. 23B, the main controller 81 does not cover the whole, but covers only a part of the main controller 81, specifically, the upper edge of the main controller 81. And only one side edge portion is covered.

  The one side edge is the side where the seal seal 125 is not provided. Therefore, the seal seal 125 is not covered by the back pack unit 15 and is sealed when the gaming machine body 12 is rotated forward with respect to the outer frame 11 to expose the back side of the gaming machine body 12. It becomes easy to bring the reader device closer to the seal 125 side.

  As shown in FIG. 22, a part of the plurality of connectors 121a to 121e is provided on the upper edge portion of the main controller 81 covered with the protective cover portion 94. These connectors 121a to 121c are The main control board 101 is electrically connected to a device such as the magnet detection sensor 109 provided on the game board 24 side. Therefore, the work for performing the electrical connection is basically performed in a state where the back pack unit 15 is opened, and there is a problem even if the connectors 121a to 121c are covered by the protective cover portion 94. Does not occur.

  On the other hand, the remainder of the plurality of connectors 121a to 121e is provided at the lower edge of the main controller 81. These connectors 121d and 121e are used for electrical connection between the main control board 101 and devices provided on the back pack unit 15 side such as the payout control device 97 and the power supply and launch control device 98. . Accordingly, by preventing the connectors 121d and 121e from being covered with the protective cover portion 94, it is possible to easily connect the wires to the connectors 121d and 121e even when the back pack unit 15 is closed. It becomes possible. Further, the area that is not covered by the protective cover portion 94 in the main control device 81 includes the rear area of the MPU 102.

  Incidentally, the protective cover part 94 is formed to be transparent, specifically, colorless and transparent so that the area covered by the protective cover part 94 can be seen from the outside in a state where the back pack unit 15 is closed. Yes. Therefore, even if the upper edge or the like of the main controller 81 is covered with the protective cover 94 as described above, the covered area can be visually observed with the back pack unit 15 closed. .

  As shown in FIGS. 22 and 23 (a), a large number of heat radiation holes 94a are formed in the protective cover portion 94 so as to penetrate the protective cover portion 94 inward and outward. The shield plate 130 is provided so as to be supported by the protective cover portion 94 by being hooked on the lower end side heat radiation hole 94a among the large number of heat radiation holes 94a. The shield plate 130 will be described in detail below with reference to FIGS. 24 (a) to 24 (c).

  As shown in FIG. 24A, the shield plate 130 is formed by attaching a noise suppression sheet 132 to a base portion 131 that determines the shape of the shield plate 130. The base 131 and the noise suppression sheet 132 are transparent so that the area covered by the shield plate 130, that is, the main control device 81 and the inside thereof can be seen with the shield plate 130 attached, specifically, colorless and transparent. Is formed. Moreover, the noise suppression sheet | seat 132 suppresses that the said electromagnetic wave noise permeate | transmits and reflects the noise suppression sheet | seat 132 by converting electromagnetic wave noise into heat.

  24 (b) and 24 (c), the shield plate 130 is identical to the plate-like portion 133 that overlaps the surface of the main controller 81 from the back of the pachinko machine 10 and the peripheral portion of the plate-like portion 133. A plurality of standing wall portions 134a and 134b formed to stand in the direction and a hook portion 135 for hooking on the heat radiation hole 94a are integrally formed. The hook portions 135 are provided in a pair of left and right at the upper edge of the plate-like portion 133. As shown in FIG. 22, the pair of hook portions 135 are respectively formed on the lower edge side of the protective cover portion 94. The heat radiating hole 94a is hooked and supported.

  Although description by illustration is abbreviate | omitted, although the shield board 130 is being fixed to the protective cover part 94 using not only the hook part 135 but double-sided tape, it is arbitrary whether the fixation by the said double-sided tape is performed. It is. In addition, the shield plate 130 may be fixed to the protective cover portion 94 using a fixing tool such as a screw, or may be fixed using an adhesive.

  However, the shield plate 130 is not fixed to the main controller 81 and is not fixed to the inner frame 13 and the game board 24 side. Thereby, when the back pack unit 15 is rotated with respect to the inner frame 13, it is not necessary to remove the shield plate 130. Therefore, it is necessary to rotate the back pack unit 15 during maintenance of the main controller 81. In this case, workability does not deteriorate.

  In the state where the shield plate 130 is supported as described above, the plate-like portion 133 is located in a region (hereinafter also referred to as a lower region 94b) below the hooked heat radiation hole 94a in the protective cover portion 94. On the other hand, it overlaps from the back of the pachinko machine 10 and overlaps from the back of the pachinko machine 10 to the area of the surface of the main controller 81 that is not covered by the protective cover 94. That is, the shield plate 130 is provided so that the range covered from the rear by the protective cover portion 94 is extended to substantially the entire main controller 81.

  As described above, the shield plate 130 overlaps the lower region 94b of the protective cover portion 94 from the rear of the pachinko machine 10, and further extends in the protective cover portion 94 to overlap one side edge of the main controller 81. The pachinko machine 10 also overlaps from behind. The adhesive fixing with the double-sided tape is performed on the lower region 94b and the extended region 94c. Therefore, even if an attempt is made to insert an unauthorized jig on the main controller 81 side through a boundary portion between the lower region 94b and the shield plate 130 or a boundary portion between the extended region 94c and the shield plate 130, it is difficult to do so. .

  In addition, on the back surface of the plate-like portion 133, a ridge portion 136 that stands up toward the main control device 81 side and extends along the long side portion of the main control device 81 is integrally formed. As shown in FIG. 23 (b), the main controller 81 has a stepped surface 126 formed on its surface so that the upper end side is recessed on the backside, and the protrusion 136 from above the stepped surface 126 is formed from above. It is in a contact state. Thereby, the weight load of the shield plate 130 is also received by the main controller 81, and the shield plate 130 can be supported in a stable state.

  In the region where the shield plate 130 overlaps on the surface of the main controller 81, the MPU 102 and its surroundings (first port driver 101a, second port driver 101b, third signal path LN3, fourth signal) on the surface of the substrate box 83. An area that is opposite to the area provided with the path LN4 and the fifth signal path LN5 is included. Therefore, the MPU 102 and its periphery are covered not only by the board box 83 but also by the shield plate 130. In this case, the noise suppression sheet 132 is provided at least in the facing area so as to constitute the surface of the shield plate 130. More specifically, the noise suppression sheet 132 is provided on the entire surface or substantially the entire surface of the shield plate 130. The noise suppression sheet 132 is formed so as to be impermeable to electromagnetic waves generated with signal output from the MPU 102. As a result, even if an illegal jig is inserted and the tip portion thereof is disposed behind the shield plate 130, it becomes possible to disable detection of noise accompanying the signal output from the MPU 102.

  The shield plate 130 does not cover the connectors 121 d and 121 e for electrical connection with the payout control device 97 in the main control device 81, the power supply and launch control device 98, and the initialization switch 123. A plurality of exposed hole portions 137a to 137c are formed. These exposure holes 137a to 137c are formed to correspond to the respective connectors 121d and 121e and the initialization switch 123 on a one-to-one basis, thereby narrowing the exposed area. As shown in FIGS. 24B and 24C, some of the exposed holes 137 a to 137 c are formed as through holes spaced from the peripheral edge of the plate-shaped part 133, and the rest Is formed as a recess recessed from the peripheral edge of the plate-like portion 133.

  As shown in FIGS. 23 (a) and 23 (b), the standing wall portions 134a and 134b formed on the shield plate 130 have side surfaces that are not covered by the protective cover portion 94 in the main controller 81, and Each lower surface is formed so as to cover from the outside.

  With respect to the side surface covering, the standing wall portion 134 a is formed so as to cover the side surface of the bulging portion that bulges to the front side in the case body on the front side of the substrate box 83. This makes it difficult to insert an unauthorized jig between the shield plate 130 and the main control device 81 from the side of the main control device 81 that is not covered by the protective cover 94. However, the seal seal 125 is not covered by the side wall 134a, that is, the shield plate 130. Thereby, it is possible to prevent the shield plate 130 from obstructing the operation of reading the identification information from the IC tag of the seal seal 125 using the reader device.

  As for the lower surface covering, the exposed wall portions 134b for the lower surface are formed due to the fact that some exposed hole portions 137a and 137b are formed so as to be recessed from the peripheral edge portion of the plate-like portion 133 as described above. Are formed intermittently. By forming the standing wall portion 134 b for the lower surface, it is difficult to insert an unauthorized jig between the shield plate 130 and the main control device 81 from the lower surface side of the main control device 81. In particular, as described above, the illegal jig is inserted from the lower end side of the gaming machine main body 12 and the leading end portion of the illegal jig is further guided upward toward the main control device 81. It is easy to reach the tip of the illegal jig. On the other hand, since the standing wall part 134b is formed so as to cover the lower surface, the leading end portion of the illegal jig that has reached the lower surface of the main control device 81 is further connected to the main control device 81 and the shield plate 130. It is suppressed that it enters between.

  Further, as described above, the lower surface standing wall portion 134b is formed intermittently in relation to the exposed hole portions 137a and 137b. However, the exposed hole portions 137a and 137b are provided with the dispensing control device 97, the power source and the firing control. It is provided with respect to connectors 121d and 121e for main controller 81 to make electrical connection with device 98. Since the payout control device 97 and the power supply / launch control device 98 exist below the main control device 81, the wires connected to the connectors 121d and 121e are downward with reference to the connectors 121d and 121e. It extends. Therefore, even if the standing wall portion 134b for the lower surface is formed intermittently, the intermittent portion is substantially covered with the wiring, and the main controller 81 is connected to the intermittent portion using the intermittent portion. Even if an illegal jig is inserted between the shield plate 130 and the shield plate 130, it is difficult to do so.

  In this embodiment, the processing configurations of the first to eighth patterns described in the first embodiment are not provided, but the processing configurations of any of these first to eighth patterns are not provided. May be provided.

  According to the present embodiment described in detail above, since the shield plate 130 is provided so as to cover the main controller 81 from the back of the pachinko machine 10, the fraudulent conducts lottery in the timer interruption process (FIG. 9). In order to illegally grasp the time required for the random number update process (step S202), even if an illegal jig is inserted behind the pachinko machine 10 of the main controller 81 to detect noise associated with signal output from the MPU 102, Can be disabled.

  By the way, according to the above-described configuration in which the shield plate 130 is provided, the electromagnetic wave noise accompanying the signal output from the MPU 102 is detected, and the processing time and processing timing other than the time required for the lottery random number update processing are illegally grasped. Actions can also be disabled. Further, it is possible to cope with an act of obtaining an unauthorized privilege by causing an abnormality in the operation of the MPU 102 by applying electromagnetic noise to the MPU 102 from the outside of the main control device 81.

Trying to identify it is difficult to do. In particular, even if the processing time is illegally read as described above, it cannot be specified whether the processing time corresponds to the specific update mode or the sequential update mode. It corresponds to all numerical information included in the numerical range. If it does so, even if it tries to manipulate the progress of a game illegally using the processing time, it becomes substantially impossible. Therefore, it is difficult to illegally manipulate the progress of the game through reading the processing time.

  According to the processing configuration of feature A8, numerical information is sequentially updated toward one boundary in a predetermined numerical range, and when one boundary in a predetermined numerical range is exceeded, the other boundary is supported. The processing for setting the numerical information can be suitably carried out, but the processing time required for setting the numerical information is considered to be longer in the latter. Then, an illegal act is assumed in which the processing time between the first processing timing and the second processing timing is illegally read and the timing at which the numerical information corresponding to the other boundary is obtained is specified.

  According to the feature A9, since the time difference between the first processing time and the second processing time does not exist or is indistinguishable, it is specified from the processing time between the first processing timing and the second processing timing. Even if it is attempted to specify whether the update mode or the sequential update mode is specified, it is impossible or difficult to perform.

  Feature A10. The adjustment unit executes the boundary setting process when the numerical value update process is completed in the sequential update mode without executing the boundary setting process as a result of the boundary determination process, and when the boundary determination process is performed as a result of the boundary determination process. By adding a delay time in a situation where the process branches according to the determination result of the boundary determination process, at least when the numerical information update process is completed in the specific update mode, The gaming machine according to Feature A9, wherein a time difference between the first processing time and the second processing time is prevented from occurring or is reduced.

  According to the feature A10, the above-described excellent effect can be achieved with a relatively simple processing configuration of adding a delay time. Further, according to this configuration, the processing time is adjusted on the destination side where the processing branches according to the determination result by the boundary determination processing, so that the processing configuration for adjusting the processing time can be simplified.

When the boundary setting process is executed as a result of the boundary determination process, the adjustment unit executes the determination destination process of the boundary determination process by changing the data of the program counter by the first data. On the other hand, if the boundary setting process is not executed as a result of the boundary determination process, the data of the program counter is changed by the second data having a larger data amount than the first data. The gaming machine according to any one of features A8 to A10, wherein the time difference is eliminated or reduced while the determination destination process of the boundary determination process is executed.

  When the process according to the result of the determination process is executed, the time required to start the process of the determination destination becomes longer as the data amount of the program counter is changed. In this case, according to the feature A11, in view of the fact that the former processing time is longer between the case where the boundary setting process is executed and the case where the boundary setting process is not executed, the result of the determination process is When the above process is executed, the amount of data changed in the program counter is smaller than in the latter case. As a result, it is possible to suppress the illegal acts as described above while suppressing the processing time of each processing time of the numerical information update processing from being prolonged.

  The inventions of the feature A group to the feature E group are effective for the following problems.

  A gaming machine such as a pachinko gaming machine is known as a kind of gaming machine. Such a gaming machine, for example, performs a random lottery on the condition that a ball enters the operation port, and in the case of winning, a privilege such as opening a big winning port is given to the player. Here, in the case of lottery, the numerical information is acquired from numerical information storage means such as a random number counter that sequentially updates the numerical information in a predetermined numerical range, and whether or not the numerical information corresponds to the predetermined numerical information. This is done by determining.

  As numerical information storage means, a configuration is known that uses an area for a predetermined number of bits in a read / write memory provided attached to a control means such as a CPU. In this case, for example, +1 is updated every minute time unit such as several ms, and when the maximum value is reached, the value is returned to the minimum value.

  More specifically, if the predetermined numerical range is 0 to 299, the numerical information starts from 0 and returns to 0 when it reaches 299. Such numerical information is acquired at the timing of entering the operation port, and when the numerical information is numerical information corresponding to the jackpot, it is processed as winning (see, for example, JP-A-2003-245455).

  However, since the numerical information storage means that loops as described above periodically changes the numerical information periodically, there is no end to fraudulent acts that intentionally target the numerical information corresponding to the winning.

  As a countermeasure against such an illegal act, there is considered a method of irregularly changing the initial value of the next lap when the numerical information is updated once. According to this method, the periodicity of numerical information is lost, and it is relatively difficult to intentionally acquire numerical information corresponding to winning.

For example, even when the initial value of each lap is irregular as described above, processing required for updating when updating to predetermined numerical information, such as when the minimum value becomes “0”, etc. It is conceivable that the time fluctuates as compared to other cases, and a fraudulent act in which the fluctuation of the processing time is read from the outside and the numerical information corresponding to the winning is intentionally targeted is assumed.

There is.

  In addition, it is conceivable that the numerical information used for the lottery different from the jackpot lottery is fraudulent with respect to the acquisition, and such numerical information has the same problem.
