Description

  The present invention relates to a slot machine.

  In the slot machine, when the start lever is operated after the insertion of medals or the operation of the bet button, three reels each having a plurality of kinds of symbols arranged on the peripheral surface thereof start to rotate all at once. In addition, a plurality of winning combinations are set, and a lottery (internal lottery) relating to the winning combinations is performed when the start lever is operated. Thereafter, when a reel stop button provided corresponding to each reel is operated, the reel corresponding to the operated reel stop button stops. When all reels stop, one game is over. When a combination of symbols corresponding to any combination is arranged on the winning line when all the reels are stopped, the combination becomes a winning combination, and a predetermined number of medals are paid out depending on the combination.

  The mainstream slot machines in recent years have an AT (Assist Time) function. In the state where the AT function is operating (AT state), when a specific winning combination is won in the internal lottery, a notification for guiding an operation (such as pressing order of three reel stop buttons) for winning the winning combination Is made. By making this notification, it is possible to prevent so-called oversight, such that a winning combination for a role cannot be obtained even though the winning combination is won in the internal lottery.

  The entry into the AT state is determined by AT lottery. The AT lottery is performed, for example, on a sub-board that is communicably connected to the main board on which the internal lottery is performed when a rare small role with a low winning probability is won in the internal lottery. In this case, information related to the winning combination in the internal lottery is transmitted from the main board to the sub board as information necessary for execution of the AT lottery. Then, when a signal indicating that the rare combination is won by the internal lottery is received by the sub-board, the AT lottery is performed on the sub-board using this as a trigger.

  In such a slot machine, there is a risk of so-called hanging gossip. In other words, connect unauthorized parts to cables and connectors for connecting the main board and the sub board, and in a short time, repeatedly send a signal indicating that the illegal part was elected to the sub board from the unauthorized parts, By repeatedly performing the AT lottery on the sub-board, there is a risk that an illegal act of entering the AT state may be performed. If such a fraudulent act is performed, an unexpected ball (medal paid out by winning) in the hall where the slot machine maker or the slot machine is installed is illegally obtained.

  An object of the present invention is to provide a slot machine that can prevent hanging hanging.

  In order to achieve the above object, a slot machine according to the present invention has a plurality of symbol arrangements, a plurality of symbol display means for variably displaying and stopping the symbol, and after a predetermined condition is satisfied, A start instructing unit operated to instruct the start of symbol variation display by a plurality of symbol display units, and corresponding to each of the symbol display units, and instructing to stop symbol variation display by the symbol display unit A plurality of stop instructing means operated to perform, a main board electrically connected to the symbol display means, the start instructing means and the stop instructing means, and a main board communicably connected to the main board, And a sub-board that unilaterally receives a signal from the board and executes control based on the received signal.

In the slot machine according to one aspect of the present invention, a period from when the predetermined condition is satisfied until an end signal indicating the end of the game is output is defined as one game. A condition establishment signal indicating that a predetermined condition has been established, a start operation signal indicating that the start instruction means has been operated, a change start signal indicating that a start of symbol change display by the symbol display means has been commanded, and the plurality A plurality of stop operation signals indicating that each of the stop instruction means is operated are transmitted to the sub-board in this order, and after all the stop instruction means are operated, the end signal is transmitted to the sub-board. A predetermined signal other than the start operation signal, the fluctuation start signal, the stop operation signal, and the end signal is transmitted to the sub-board. Validity / invalidity of the input of the predetermined signal is set between each signal input of the condition establishment signal, the start operation signal, the variation start signal, the plurality of stop operation signals, and the end signal, and the specific signal Between the signal inputs, the number of the predetermined signals that enable the input is limited to a predetermined number, and the input of the predetermined signals between the signal inputs in which invalidity of the input of the predetermined signals is set was invalid, it invalidates the input of the predetermined signal, wherein exceeds the number of predetermined between the specific of the signal input.

  The slot machine is provided with a plurality of symbol display means. Each symbol display means has an array of a plurality of types of symbols, and these symbols are variably displayed and stopped. Further, the slot machine is provided with start instruction means and stop instruction means. When the start instructing unit is operated after the predetermined condition is established, the symbol variation display by each symbol display unit is started. The stop instructing means is provided corresponding to each symbol display means. When the stop instructing means is operated after the symbol variation display is started, the symbol displaying means corresponding to the operated stop instructing means. The change display of the symbol is stopped (the symbol is stopped). When all stop instruction means are operated, one game is finished.

  Each symbol display means, start instruction means and stop instruction means are connected to the main board. In addition, a sub board is connected to the main board so as to be communicable.

  The main board indicates that during one game, a condition establishment signal indicating that a predetermined condition has been established, a start operation signal indicating that the start instruction means has been operated, and the start of symbol variation display by the symbol display means have been commanded. A change start signal and a plurality of stop operation signals indicating that the plurality of stop instruction means are respectively operated are transmitted to the sub-board in this order, and then an end signal indicating the end of one game is transmitted to the sub-board. Further, the main board transmits a predetermined signal other than the start operation signal, the fluctuation start signal, the stop operation signal, and the end signal to the sub board at a predetermined timing.

  On the sub-board, validity / invalidity of input of a predetermined signal is set between signal inputs of a condition establishment signal, a start operation signal, a fluctuation start signal, a plurality of stop operation signals, and an end signal. Even if a predetermined signal is input to the sub-board between signal inputs in which the input of the predetermined signal is set to be invalid (hereinafter referred to as “invalid period” in this section), all the inputs are invalidated. .

  In addition, between specific signal inputs, the number of predetermined signals that validate the input is limited to a predetermined number. Therefore, even if a predetermined number of signals exceeding a predetermined number are input between specific signal inputs, all inputs of the predetermined signals exceeding the predetermined number are invalidated.

  When the input of the predetermined signal is invalidated, the control by the sub-board is not performed based on the predetermined signal.

  Therefore, even if an unauthorized part is connected to the sub board and a predetermined signal is repeatedly transmitted from the unauthorized part to the sub board in a short time, the predetermined signal is not input from the unauthorized part to the sub board during the invalid period. Since all are invalidated, the control based on the input of a predetermined signal from the unauthorized part is not performed. Further, since only a predetermined number of predetermined signals are input between specific signal inputs, the number of controls exceeding the predetermined number is not performed.

  In this way, the period during which the input of a predetermined signal to the sub-board is valid is limited, and more than a predetermined number of controls are not performed between specific signal inputs. Even if the components are connected, the number of times of control based on the input of a predetermined signal performed on the sub-board during one game cannot be increased so much. Therefore, there is no advantage in connecting unauthorized parts to the sub-board. As a result, it is possible to prevent an unauthorized act of connecting an unauthorized part to the sub-board, that is, a so-called hanging iron.

  The main board is provided with a lottery means for executing a lottery for a lottery and out of play for each game, and a predetermined signal indicates information on the winning combination in the lottery by the lottery means A signal may be included.

  In this case, a period from the input of the start operation signal to the input of the fluctuation start signal is included between the specific signal inputs, and the number of winning combination signals that validate the input is limited to 1 in this period. It is preferable.

  As a result, if one winning combination signal is transmitted from the main board to the sub board during the period from the start operation signal input to the fluctuation start signal input, the further input of the winning combination signal to the sub board is invalidated. To be. Therefore, even if an unauthorized part that repeatedly transmits a winning combination signal is connected to the sub board, the input of the winning combination signal from the unauthorized part to the sub board can be invalidated.

  The main board is provided with gaming state setting means for setting a plurality of gaming states with different lottery tables used for lottery in the lottery means, and the gaming state set by the gaming state setting means in the predetermined signal A gaming state signal representing information about the game may be included.

  In this case, a period from the input of the condition satisfaction signal to the input of the start operation signal is included between the specific signal inputs, and the number of gaming state signals for which the input is valid is limited to 1 in this period. It is preferable.

  As a result, if one gaming state signal is transmitted from the main board to the sub-board during the period from the input of the condition satisfaction signal to the input of the start operation signal, the further input of the gaming state signal to the sub-board is invalidated. To be. Therefore, even if an unauthorized part that repeatedly transmits a gaming state signal is connected to the sub-board, the input of the gaming state signal from the unauthorized part to the sub-board can be invalidated.

  In the lottery object, when the pushing order of the plurality of stop instructing means coincides with the predetermined correct pushing order, the drawing is advantageous to the player as compared with the case where the pushing order does not coincide with the correct pushing order. The combination in which the combination is stopped and displayed by a plurality of symbol display means may be included. The predetermined signal includes a signal related to the push order notification lottery, and the sub-board determines whether or not to acquire the right to notify the information related to the correct push order based on the signal related to the push order notification lottery. The push order notification lottery execution means for executing the push order notification lottery may be provided.

  In this case, in the period from the start operation signal input to the fluctuation start signal input (between specific signal inputs), only one signal related to the push order notification lottery is transmitted from the main board to the sub-board, and the input to the sub-board. It is preferable that the number of signals relating to the push order notification lottery that is effective is limited to one.

  During the invalid period, all signals related to the push order notification lottery to the sub-board are invalidated, so the push order notification lottery is not executed. Also, during the period from the input of the start operation signal to the input of the fluctuation start signal, only the input of the signal relating to one push order notification lottery is valid, and the further inputs are invalidated. Is not performed more than once. Therefore, even if an unauthorized part is connected to the sub board and a signal related to the push order notice lottery is repeatedly transmitted from the unauthorized part to the sub board in a short time, the push order notice lottery performed in one game is only once. . Therefore, it is not possible to illegally acquire the right to notify information related to the correct answer pressing order due to the hanging goto. As a result, it is possible to effectively prevent dangling from being performed in a model in which information on the correct answer pressing order is notified.

  The sub-board is preferably provided with order determining means for determining whether a condition establishment signal, a start operation signal, and a variation start signal are input in this order for each game.

  If the condition satisfaction signal, the start operation signal, and the fluctuation start signal are not input in this order, it is determined that an abnormality such as a signal being transmitted from an unauthorized part to the sub board has occurred, and, for example, to the sub board The input of the predetermined signal can be invalidated.

In the slot machine according to another aspect of the present invention, a period from when the predetermined condition is satisfied until an end signal indicating the end of the game is output as one game. A condition establishment signal indicating that a predetermined condition has been established, a start operation signal indicating that the start instruction means has been operated, a change start signal indicating that a start of symbol change display by the symbol display means has been commanded, and the plurality A plurality of stop operation signals indicating that each of the stop instruction means is operated are transmitted to the sub-board in this order, and after all the stop instruction means are operated, the end signal is transmitted to the sub-board. In addition, a predetermined signal other than the start operation signal, the fluctuation start signal, the stop operation signal, and the end signal is transmitted to the sub board. Matter establishing signal, the start operation signal, the change start signal, the and valid / invalid is set in the input of a predetermined signal between the respective signal inputs of said plurality of stop operation signal and the end signal, the predetermined The input of the predetermined signal is invalidated between the signal inputs in which invalidity of signal input is set, and the condition establishment signal, the start operation signal, and the variation start signal are displayed on the sub-board for each game. Are included in this order, and the sub-board does not input the condition establishment signal, the start operation signal, and the variation start signal in this order by the order determination unit. If, it invalidates the input of the predetermined signal.

  On the sub-board, validity / invalidity of input of a predetermined signal is set between signal inputs of a condition establishment signal, a start operation signal, a fluctuation start signal, a plurality of stop operation signals, and an end signal. Even if a predetermined signal is input to the sub-board during the invalid period, all the inputs are invalidated.

  When the input of the predetermined signal is invalidated, the control by the sub-board is not performed based on the predetermined signal.

  Further, in the sub board, it is determined for each game whether or not the condition establishment signal, the start operation signal, and the variation start signal are input in this order.

  If the condition satisfaction signal, the start operation signal, and the fluctuation start signal are not input in this order, it is determined that an abnormality such as a signal being transmitted from an unauthorized part to the sub board has occurred, and, for example, to the sub board The input of the predetermined signal can be invalidated.

  Thus, the period during which the input of the predetermined signal to the sub-board is validated is limited, and further, the condition establishment signal, the start operation signal, and the fluctuation start signal need to be input to the sub-board in this order. Even if an unauthorized part is connected to the sub board, the number of times of control based on the input of a predetermined signal performed on the sub board during one game cannot be increased so much. Therefore, there is no advantage in connecting unauthorized parts to the sub-board. As a result, it is possible to prevent an unauthorized act of connecting an unauthorized part to the sub-board, that is, a so-called hanging iron.

  An illegal component that transmits a condition establishment signal, a start operation signal, a fluctuation start signal, a plurality of stop operation signals, an end signal, and a predetermined signal in the same order as the transmission sequence from the main board is connected to the sub board and It is conceivable that those signals are repeatedly input to the sub-board in a short time.

  Therefore, the sub-board is provided with a re-input determination unit that determines whether or not the variation start signal is input again after the minimum time required for digesting one game has elapsed since the input of the variation start signal. It is preferable that

  When the change start signal is input again after the input of the change start signal until the minimum time required for one game to elapse, it can be determined that an unauthorized part is connected to the sub-board. The input of a predetermined signal from the unauthorized component to the sub-board can be invalidated. As a result, even if a plurality of start operation signals, fluctuation start signals, a plurality of stop operation signals, end signals, and predetermined signals are input from the unauthorized part to the sub board during one game, the sub board is based on the predetermined signals. It is possible to prevent the control from being performed multiple times.

  Therefore, it can prevent more effectively that hanging goto is performed.

  According to the present invention, even if an unauthorized part that repeatedly transmits a predetermined signal in a short time is connected to the sub board, the number of times of control based on the input of the predetermined signal performed on the sub board during one game is increased so much. I can't. Therefore, it is possible to prevent a fraudulent act of connecting a fraudulent part to the sub-board, so-called hanging goto.

To do. Moreover, the output of the sound effect from the speakers 23 and 25 is controlled.

  FIG. 3 is a flowchart showing a flow of main control executed by the main control board.

  In the main control board 31, the CPU 41 repeatedly executes the main control shown in FIG.

  Prior to the start of the game, the presence / absence of an operation signal input from the MAX bet button 15, the 1-sheet bet button 16 and the 2-sheet bet button 17 and the presence / absence of a detection signal input from the medal insertion sensor 55 are repeatedly examined ( Step S1).

  If any operation signal or detection signal is input, it is determined that a medal is bet (YES in step S1), and it is checked whether or not an operation signal is input from the start lever 18 (step S2). If no operation signal is input from the start lever 18 (NO in step S2), whether or not the operation signal is input from the MAX bet button 15, the 1-bet button 16 and the 2-bet button 17 and the medal insertion sensor 55 The presence / absence of the detection signal is checked again (step S1).

  When an operation signal from the start lever 18 is input, that is, when the start lever 18 is operated (YES in step S2), the medal block solenoid 53 is controlled to discharge the medal to be inserted from the medal insertion slot 14. Is placed in the tray 21 and subsequent insertion of medals is prohibited (step S3).

  In addition, when the start lever 18 is operated, a combination lottery with a plurality of types of combinations and outliers as lotteries is performed (step S4).

  The role includes a watermelon role, which is a rare role with a relatively low probability of winning, a bell role, which is a push order small role in which the number of medals paid out varies depending on the push order, and one game is executed without a bet of medals Replay roles that are permitted are included.

  When winning the watermelon role, it is allowed that a combination of symbols of “watermelon”-“watermelon”-“watermelon” is arranged on the winning line.

  When winning the role of Bell, the combination of symbols "Bell A"-"Bell A"-"Bell A" and the combination of symbols "Bell A"-"Bell B"-"Bell B" are arranged on the winning line. It is acceptable. “Bell A” and “Bell B” are the same kind of designs with a bell as a motif, but they are not the same. When the pressing order of the left stop button 19L, the middle stop button 19C and the right stop button 19R matches a predetermined correct answer pressing order, the combination of symbols "Bell A"-"Bell A"-"Bell A" is on the winning line A relatively large number (for example, 12) of medals are paid out. On the other hand, when the left stop button 19L, the middle stop button 19C, and the right stop button 19R are operated in a different order from the correct pressing order, the combination of symbols "Bell A"-"Bell B"-"Bell B" is the winning line. A relatively small number (for example, three) of medals are paid out in line. When the game state is an RT (replay time) state in which the winning probability of the replay role is relatively high, a combination of symbols “Bell A”-“Bell B”-“Bell B” is on the winning line. The game state shifts from the RT state to the normal state where the winning probability of the replay role is relatively low.

  When winning the replay role, a combination of symbols “Replay A”-“Replay A”-“Replay A” and a combination of symbols “Replay A”-“Replay B”-“Replay B” are arranged on the winning line. It is acceptable. “Replay A” and “Replay B” are the same type of symbols, but are not the same. When the pressing order of the left stop button 19L, middle stop button 19C, and right stop button 19R matches the predetermined correct answer pressing order, the combination of symbols of "Replay A"-"Replay A"-"Replay A" is on the winning line The execution of one game is permitted without betting medals. If the gaming state is the normal state, the gaming state shifts from the normal state to the RT state. On the other hand, when the left stop button 19L, the middle stop button 19C, and the right stop button 19R are operated in a different order from the correct pressing order, the combination of symbols “Replay A”-“Replay B”-“Replay B” is the winning line. The execution of one game is permitted with no medals bet.

  In the role lottery, a random number value is acquired from a random number counter in response to the start lever 18 being operated. Then, a lottery table corresponding to the gaming state is read from the ROM 42, and a winning combination or a loss is determined based on the random number value and the lottery table. For example, when the gaming state is the normal state, the first lottery table 57 is read from the ROM 42. When the gaming state is the RT state, the second lottery table 58 is read from the ROM 42. In the first lottery table 57, the winning probability of the replay role is set to 1 / 7.3, and in the second lottery table 58, the winning probability of the replay role is set to 1 / 1.5.

  Thereafter, a drive pulse signal is supplied to the stepping motors 51L, 51C, 51R, and rotation of the reels 4L, 4C, 4R is started (step S5). When the rotation speed of the reels 4L, 4C, 4R becomes constant, operation signals from the left stop button 19L, the middle stop button 19C, and the right stop button 19R can be received.

  Thereafter, it is repeatedly checked whether or not the left stop button 19L, middle stop button 19C and right stop button 19R are operated (step S6).

When the left stop button 19L, middle stop button 19C, and right stop button 19R are selectively operated (YES in step S6), the supply of drive pulse signals to the stepping motors 51L, 51C, 51R is stopped. Thereby, the rotation of the reels 4L, 4C, 4R is stopped (step S7). The timing for stopping the supply of the drive pulse signal to the stepping motors 51L, 51C, 51R is controlled based on the timing when the left stop button 19L, the middle stop button 19C and the right stop button 19R are operated, and the result of the lottery drawing. The

  When the rotation of all the reels 4L, 4C, 4R is stopped (YES in step S8), it is determined whether or not a combination of symbols corresponding to the winning combination is arranged on the activated pay line, that is, the winning combination Whether or not is established is determined, and if the winning combination is established, it is determined that a winning is achieved (step S9). The number of medals set for each winning combination is paid out for winning.

  Thereafter, if the number of credits has not reached 50, the medal block solenoid 53 is controlled so that the discharge destination of medals inserted from the medal insertion slot 14 is set as the medal storage section, and the insertion of medals from the medal insertion slot 14 is performed. Allowed (step S10).

  Thus, the main control ends. One game in the slot machine 1 is from the bet of medals to the end of the main control.

  FIG. 4 is a diagram illustrating a transmission order of signals from the main control board to the effect control board during one game.

  When a medal is bet, a bet signal LINEBET indicating that a game start condition is satisfied is transmitted from the main control board 31 to the effect control board 32. The same number of bet signals LINEBET as the number of medals bet are input.

  Next, when the start lever 18 is operated, a lever-on signal START0 indicating that the start lever 18 has been operated is transmitted from the main control board 31 to the effect control board 32.

  Thereafter, when the supply of the drive pulse signal from the main control board 31 to the stepping motors 51L, 51C, 51R is started, the reels 4L, 4C, 4R start to rotate from the main control board 31 to the effect control board 32. A reel rotation start signal START1 indicating that the start of symbol variation display by rotation of the reels 4L, 4C, 4R has been commanded is transmitted.

  Thereafter, when the left stop button 19L, the middle stop button 19C and the right stop button 19R are operated, the left stop button 19L, the middle stop button 19C or the right stop button is moved from the main control board 31 to the effect control board 32 for each operation. A stop operation signal STOP indicating that the button 19R has been operated is transmitted.

  When the main control shown in FIG. 3 ends, a game end signal GENTRY indicating the end of one game is transmitted from the main control board 31 to the effect control board 32.

  Also, during one game, the main control board 31 to the effect control board 32, a winning combination signal ENS indicating information related to the lottery on the main control board 31, and a gaming state indicating what state the gaming state is. Signal RT is transmitted.

  One winning combination signal ENS is transmitted in a period from transmission of the lever-on signal START0 to transmission of the reel rotation start signal START1, and is not transmitted in any other period.

  One gaming state signal RT is transmitted between the transmission of the bet signal LINEBET and the transmission of the lever-on signal START0, and from the transmission of the stop operation signal STOP during the period from the transmission of the lever-on signal START0 to the transmission of the reel rotation start signal START1. It may be transmitted after the period until the game end signal GENTRY is transmitted and after the game end signal GENTRY is transmitted.

  FIG. 5 is a flowchart showing the flow of processing executed on the effect control board.

  In the effect control board 32, the CPU 61 repeatedly checks whether or not the winning combination signal ENS is input from the main control board 31 (step S11).

  When the winning combination signal ENS is input to the effect control board 32 (YES in step S11), the CPU 61 performs a watermelon combination that is a rare small combination in the combination lottery performed on the main control board 31 based on the winning combination signal ENS. It is determined whether or not is won (step S12).

  If the watermelon combination is not won (NO in step S12), the processing shown in FIG. 5 is immediately terminated.

  If the watermelon combination is won (YES in step S12), an AT lottery for determining whether or not to enter the AT state is executed (step S13).

  Then, it is determined whether or not the AT lottery is won (step S14).

  If the AT lottery is not won (NO in step S14), the process shown in FIG. 5 is immediately terminated.

  When the AT lottery is won (YES in step S14), the AT state is entered (step S15).

  In addition, in response to the winning of the AT lottery, the AT state may be entered immediately, or the entry into the AT state is stocked (held), and a predetermined timing thereafter (for example, after the bonus game ends) You may enter the AT state.

  In the AT state, when the bell role is won in the role lottery performed on the main control board 31, the drive circuit 65 is controlled by the effect control board 32, and the correct answer push order regarding the bell role is displayed on the liquid crystal display 22. The Further, when the replay combination is won in the combination lottery performed on the main control board 31, the drive circuit 65 is controlled by the effect control board 32, and the correct push order regarding the replay combination is displayed on the liquid crystal display 22.

  In this way, in the AT state, the correct push order is notified by display on the liquid crystal display 22, so that the left stop button 19L, the middle stop button 19C and the right stop button 19R are operated in the correct push order. Despite the fact that the role of Bell is elected, the combination of symbols "Bell A"-"Bell A"-"Bell A" is not lined up on the winning line, or the replay role is won In addition, it is possible to prevent so-called spillage that the symbol combinations “Replay A”-“Replay A”-“Replay A” are not arranged on the winning line. Therefore, the AT state is an advantageous state for the player, and the AT lottery for determining whether or not to enter the AT state is an important lottery related to the profit of the player.

  For example, the AT state ends when a predetermined number of games (for example, 50 games) are consumed after the gaming state shifts from the normal state to the RT state and enters the so-called ART state. In the effect control board 32, the CPU 61 knows whether the current gaming state is the normal state or the RT state based on the gaming state signal RT input from the main control board 31. Then, after entering the ART state, the CPU 61 starts counting the number of games as a criterion for determining whether or not to end the AT state.

  Therefore, the winning combination signal ENS and the gaming state signal RT input from the main control board 31 to the effect control board 32 are important signals related to the AT state.

  Therefore, as shown in FIG. 4, in the effect control board 32, between the input of the bet signal LINEBET and the input of the lever-on signal START0, between the input of the lever-on signal START0 and the input of the reel rotation start signal START1, the reel rotation. Between the input of the start signal START1 and the input of the first stop operation signal STOP, between the input of the first stop operation signal STOP and the input of the second stop operation signal STOP, the second stop Between the input of the operation signal STOP and the input of the third stop operation signal STOP, between the input of the third stop operation signal STOP and the input of the game end signal GENTRY, and the input of the game end signal GENTRY and the bet signal The validity / invalidity of the input of the winning combination signal ENS and the gaming state signal RT with respect to the input of LINEBET is set.

  Specifically, between the input of the bet signal LINEBET and the input of the lever-on signal START0, the input of the winning combination signal ENS is set to be invalid, and even if the winning combination signal ENS is input to the effect control board 32, The input is invalidated. In addition, during this signal input, the number of gaming state signals RT for which input to the effect control board 32 is valid is limited to one. Therefore, when two or more gaming state signals RT are input to the effect control board 32 during this signal input, the input of the second gaming state signal RT is invalidated.

  Between the input of the lever-on signal START0 and the input of the reel rotation start signal START1, the number of winning combination signals ENS for which the input to the effect control board 32 is valid is limited to one. Therefore, if two or more winning combination signals ENS are input to the effect control board 32 during this signal input, the input of the second winning combination signal ENS is invalidated. In addition, the input of the game state signal RT is set valid between the signal inputs.

  Between the input of the reel rotation start signal START1 and the input of the first stop operation signal STOP, between the input of the first stop operation signal STOP and the input of the second stop operation signal STOP, and the second The input of the winning combination signal ENS and the gaming state signal RT is both invalid between the signal inputs between the input of the stop operation signal STOP and the input of the third stop operation signal STOP. Therefore, even if the winning combination signal ENS and the gaming state signal RT are input between the signal inputs, the inputs are invalidated.

  Between each signal input between the input of the third stop operation signal STOP and the input of the game end signal GENTRY and between the input of the game end signal GENTRY and the input of the bet signal LINEBET, the winning combination signal ENS is input. Even if the winning combination signal ENS is input to the effect control board 32, the input is disabled. In addition, the input of the game state signal RT is set valid between the signal inputs. For example, when a combination of symbols “Bell A”-“Bell B”-“Bell B” or a combination of symbols “Replay A”-“Replay A”-“Replay A” is arranged on the winning line, the gaming state is changed. Therefore, in this case, the game state signal RT is transmitted from the main control board 31 to the effect control board 32.

  Normally, one gaming state signal RT is input to the effect control board 32 between the input of the bet signal LINEBET and the input of the lever-on signal START0, the input of the lever-on signal START0 and the input of the reel rotation start signal START1. In the meantime, one winning combination signal ENS is input to the effect control board 32. Therefore, normally, the bet signal LINEBET, the gaming state signal RT, the lever-on signal START0, the winning combination signal ENS, and the reel rotation start signal START1 are input to the effect control board 32 in this order.

  Therefore, in the effect control board 32, whether or not the bet signal LINEBET, the gaming state signal RT, the lever-on signal START0, the winning combination signal ENS, and the reel rotation start signal START1 are input in this order by the CPU 61 after the bet signal LINEBET is input. Is determined. If the bet signal LINEBET, the gaming state signal RT, the lever-on signal START0, the winning combination signal ENS and the reel rotation start signal START1 are not input in this order, the CPU 61, for example, receives the winning combination signal ENS to the effect control board 32 and The input of the gaming state signal RT is invalidated. Further, under the control of the CPU 61, the fact that an error has occurred is displayed on the liquid crystal display 22, and a sound for notifying the error is output from the speakers 23, 25.

  As described above, the main control board 31 has a bet signal LINEBET indicating that the game start condition is satisfied during one game, a lever-on signal START0 indicating that the start lever 18 is operated, and the reels 4L, 4C, and 4R. Reproduction start board START1 indicating that the motor has started rotating, three stop operation signals STOP indicating that the left stop button 19L, the middle stop button 19C or the right stop button 19R are each operated in this order. Is transmitted, a game end signal GENTRY indicating the end of one game is transmitted.

  In the effect control board 32, the winning combination signal ENS and the gaming state signal RT are inputted between the signal inputs of the bet signal LINEBET, the lever-on signal START0, the reel rotation start signal START1, the three stop operation signals STOP, and the game end signal GENTRY. Valid / invalid is set. Even if the winning combination signal ENS is input to the sub-board between signal inputs in which the input of the winning combination signal ENS is set to be invalid, all the inputs are invalidated. Further, even if the gaming state signal RT is input to the sub-board between signal inputs in which the input of the gaming state signal RT is set to be invalid, all the inputs are invalidated.

  The lottery for the role lottery on the main control board 31 includes the correct push order when the push order of the left stop button 19L, the middle stop button 19C, and the right stop button 19R matches the predetermined correct push order. Compared to the case where they do not match, a combination of symbols “Bell A”-“Bell A”-“Bell A”, which is a symbol combination advantageous to the player, is included on the winning line. Further, when the pressing order of the left stop button 19L, the middle stop button 19C, and the right stop button 19R matches a predetermined correct pressing order, the pressing order does not match the correct pressing order. A replay combination in which a combination of symbols “Replay A” — “Replay A” — “Replay A”, which is a symbol combination advantageous to the user, is included. Then, the effect control board 32 executes AT lottery for determining whether or not to enter the AT state in which the correct pressing order is notified based on the winning combination signal ENS.

  Between the input of the lever-on signal START0 and the input of the reel rotation start signal START1, the number of winning combination signals ENS for which the input to the effect control board 32 is valid is limited to one. Therefore, if two or more winning combination signals ENS are input to the effect control board 32 during this signal input, the input of the second winning combination signal ENS is invalidated.

  Between the signal inputs in which the input of the winning combination signal ENS is set to be invalid, the input of the winning combination signal ENS to the effect control board 32 is all invalidated, so that the AT lottery is not executed. Also, between the input of the lever-on signal START0 and the input of the reel rotation start signal START1, only the input of one winning combination signal ENS is valid, and the input beyond that is invalidated. It will not be performed once. Therefore, even if an unauthorized part is connected to the effect control board 32, and the winning combination signal ENS (the winning combination signal ENS indicating that the watermelon role has been won) is repeatedly transmitted in a short time from the unauthorized part to the effect control board 32, There is only one AT lottery performed during one game. Therefore, it is not possible to illegally enter the AT state where the correct answer pressing order is notified by the hanging goto. As a result, it is possible to effectively prevent the hanging machine 1 from being hung in the slot machine 1.

  In the effect control board 32, whether or not the bet signal LINEBET, the gaming state signal RT, the lever-on signal START0, the winning combination signal ENS, and the reel rotation start signal START1 are input in this order by the CPU 61 after the bet signal LINEBET is input. Is determined. If the bet signal LINEBET, the gaming state signal RT, the lever-on signal START0, the winning combination signal ENS and the reel rotation start signal START1 are not input in this order, the winning combination signal ENS to the effect control board 32 and the gaming state signal RT Input is invalidated. Therefore, it is possible to more effectively prevent the hanging machine 1 from being hung in the slot machine 1.

  FIG. 6 is a diagram for explaining a process that is preferably executed by the effect control board.

  As described above, even if the bet signal LINEBET, the gaming state signal RT, the lever-on signal START0, the winning combination signal ENS, and the reel rotation start signal START1 are determined in this order, The illegal parts that transmit the signal LINEBET, the gaming state signal RT, the lever-on signal START0, the winning combination signal ENS, and the reel rotation start signal START1 in this order are connected to the effect control board 32, and these signals are transmitted from the illegal parts for a short time In response to the input of the winning combination signal ENS (the winning combination signal ENS indicating that the watermelon role has been won) because the number of signals input to the effect control board 32 and the input order of the signals are correct. There is a risk of AT lottery.

  Therefore, in the effect control board 32, the CPU 61 measures the time after the reel rotation start signal START1 is input. At the time when the next reel rotation start signal START1 is input (now_time), the minimum time required for one game, for example, 4.1 seconds has elapsed since the input of the previous reel rotation start signal START1. If not, the CPU 61 determines that an error (connection of illegal parts) has occurred, and the input of the winning combination signal ENS and the gaming state signal RT to the effect control board 32 is invalidated.

  Thus, even if a bet signal LINEBET, a gaming state signal RT, a lever-on signal START0, a winning combination signal ENS, and a reel rotation start signal START1 are repeatedly input in this order from the unauthorized part to the effect control board 32 during one game. It is possible to prevent the AT lottery from being performed a plurality of times on the effect control board 32.

  Therefore, it can prevent more effectively that hanging goto is performed.

  As mentioned above, although embodiment of this invention was described, this invention can also be implemented with another form.

  For example, as the predetermined signals input from the main control board 31 to the effect control board 32, the winning combination signal ENS and the gaming state signal RT are exemplified, but the reels 4L and 4C are delayed from the operation of the start lever 18 than usual. , 4R, in a model in which an effect of notifying that a predetermined combination has been won by a so-called freeze is performed, the predetermined signal may be a freeze signal indicating that execution of the freeze has been determined. .
