Description

  The present invention relates to a gaming machine such as a pachinko machine or a slot machine installed in a game hall such as a pachinko parlor, and more particularly, a function of disabling some functions of a gaming machine when an illegal act is performed in the gaming machine. It is related with the game machine provided with.

  Currently, there are many known gaming machines such as pachinko machines, slot machines, arrangement ball machines, sparrow ball machines, etc. that play games using game media such as game balls and medals. In these gaming machines, a game medium is awarded as a bonus according to achievement of a predetermined winning condition, such as a game ball winning in a predetermined winning slot, or a reel design that rotates in response to the insertion of medals on the winning line. Will be paid out. The paid out game media can be exchanged for goods at the prize exchange, and the player can enjoy the game even more for the purpose of acquiring the game media.

By the way, in order to acquire more game media, some players try to acquire the game media using illegal means. For example, in a slot machine that is one of the gaming machines, there is a method of illegally changing a set winning probability and illegally paying out game media. Specifically, a player who aims to gain profits illegally is operated to make a hole in the front door provided on the front of the gaming machine or forcibly open the front door to change the setting. Installed in the power supply device or setting change device, etc. by inserting a wire etc. from the gap between the game machine main body and the front door, the medal slot, the medal outlet, etc. The set value is changed by a method of short-circuiting the circuit board. For this reason, Patent Document 1 provides a detection sensor for detecting the position of the door on the front door, and invalidates the setting change operation performed when the front door is closed to prevent unauthorized setting value changes. A gaming machine is described. Further, in Patent Document 2, an enabling key is provided, and when the enabling key is not turned to the ON position, when the start lever operated to determine the setting value is operated, the setting value is the highest. Some proposals have been made to reduce the damage by setting a low setting value.
JP 2004-135844 A JP 2005-245534 A

  However, in order to confirm whether or not the setting value has been changed for the gaming machine in the gaming hall, the gaming hall manager performs a predetermined setting display operation on each gaming machine and displays the setting display provided on the gaming machine. If the set value is not displayed on the screen, it cannot be confirmed, and for this reason, it cannot be immediately known that the set value has been illegally changed. If the manager of the game hall is delayed in noticing the unauthorized setting change, the amount of damage may increase accordingly.

  Therefore, in order to keep the damage to a minimum, there can be considered a method of invalidating a part of the function of the gaming machine and making it impossible to play a game when the setting value is illegally changed. In any of the above patent documents, a method for preventing the setting value from being changed illegally has been proposed, but a method for preventing a game from being performed has not been proposed.

  The present invention has been made in view of the above circumstances, and its purpose is to minimize damage by disabling some of the functions of gaming machines whose settings have been illegally changed and making it impossible to play games. It is to provide a gaming machine that can be used.

  In order to achieve the above-mentioned object, in the gaming machine of the present invention, a game mode in which a game is performed and a winning probability of winning are selected from a plurality of types of winning probabilities, and the selected winning probability is determined by the determining means. In the gaming machine in which the setting change mode determined by is set, the determination operation of the determination means is invalidated during the setting change mode, and the determination operation of the determination means is performed when a predetermined release operation is performed. It is characterized in that a definite operation control means for validating is provided.

  Further, the confirmation means also serves as a game start means, and the confirmation operation control means determines whether or not the release operation is appropriate after the confirmation operation of the confirmation means, and the release operation is appropriate. In the game mode that has been transferred to the setting change mode, the start means starts the operation, and if the release operation is not appropriate, the game mode in the game mode that has been transferred to the setting change mode. The starting operation of the starting means is invalidated.

  According to the gaming machine of the present invention, when a setting change is made in order to change the winning probability, the function of confirming the start lever for determining the winning probability is invalidated, and a predetermined release is required to enable this. Therefore, even if the setting is changed illegally, the set value cannot be confirmed, and the player trying to perform the illegality cannot obtain many medals illegally. Can be kept to a minimum.

  The start lever also serves as a starting means for starting the game. After the setting is changed and the confirmation operation is performed, it is determined whether the release operation is different from the predetermined release operation. If it is determined that the operation is not a release operation, the player can not start the game by disabling the function of the game start operation combined with the start lever, thereby further enhancing the effect of the present invention. It will be.

To confirm the changed set value, the start lever 38 is operated (in this case, the confirmation means of the present invention).

  FIG. 4 is a block diagram showing an electrical configuration of the slot machine 3. The operation of the slot machine 3 is basically controlled by the control unit 60. The control unit 60 includes a CPU 61, a ROM 62, a RAM 64, a determination unit 65, a timing circuit 66, an electronic lottery unit 77, a winning combination determining unit 78, and a finalizing operation control unit (a finalizing operation control unit) 79. To sixth winning tables 63a to 63f, a setting change program 67, a symbol table 68, a payout table 69, and the like. For example, first to sixth winning tables 63a to 63f are prepared corresponding to the set values, and the winning probabilities are different depending on the first to sixth winning tables 63a to 63f. The winning table corresponding to the set value is read and the game is controlled. In addition to the control unit 60, the slot machine 3 includes a throw-in medal sensor 75, a start switch sensor 76, a display control unit 90, a communication interface (hereinafter referred to as communication I / F) 92, a power supply unit 94, and the like. It has been.

  The start switch sensor 76 is turned ON when the start lever 38 is operated, and transmits a signal to the CPU 61. However, when the setting change operation is performed in the setting change device 55 in the setting change mode, the start lever 38 is operated. When the start lever 38 is operated, the signal from the start switch sensor 76 is processed as a set value determination signal. When the start lever 38 is operated after betting a medal to start the game in the game mode, the start switch sensor 76 This signal is processed as a game start signal.

  The setting change program 67 stored in the ROM 62 is a program used when changing the winning probability, and the setting change key 55d inserted into the setting change key cylinder 55a is rotated from the OFF position to the ON position. It is read when the power switch 55b is turned on. When the setting change key 55d is turned 90 degrees counterclockwise, returned from the ON position to the OFF position and removed from the setting change key cylinder 55a, the execution of the setting change program 67 ends. The RAM 64 is used when the control program and the setting change program 67 are read from the ROM 62 and executed.

  The inserted medal sensor 75 is provided at the rear end portion of the selector, and detects an appropriate medal distributed by the selector among medals inserted from the medal slot 43. A detection signal output from the inserted medal sensor 75 is input to the CPU 61, and the CPU 61 detects the number of inserted medals. When the single bet button 35 and the MAX bet button 36 are pressed, a pressing signal is input to the CPU 61. The CPU 61 determines that the number of 1-3 medals inserted prior to the start of the game has been detected based on the detection signal from the inserted medal sensor 75 or one of the 1-bet button 35 and the MAX bet button 36. The number of winning lines is validated by counting based on the pressing signal input in response to this. Further, the bet number of medals inserted at the start of the game is accumulated and counted by a counter (not shown) provided in the CPU 61.

  When a medal bet is placed and the start lever 38 is operated as a game start means of the present invention, the start switch sensor 76 transmits a game start signal to the CPU 61. Receiving the game start signal, the CPU 61 rotates the first, second, and third reels 21a, 21b, and 21c based on the game execution program stored in the ROM 62, and operates the electronic lottery unit 77 and the winning combination determining unit 78. Let the lottery for the winning role start.

  The control unit 60 is provided with an electronic lottery unit 77, a winning combination determining unit 78, and a confirmation operation control unit 79. The electronic lottery unit 77 includes a random number generation unit and a random number extraction unit, and extracts one random value every time a game is started. The winning combination determination unit 78 operates in accordance with the random number extraction process in the electronic lottery unit 77, and refers to the winning table in the ROM 62 to determine whether the extracted random number is lost or a plurality of types of winning combinations. decide. Note that the lottery includes a step of extracting a random number in the electronic lottery unit 77 and a step of determining whether to become a winning combination or a plurality of types of winning combinations based on the extracted random number.

  The symbol drive control unit 82 controls the drive and stop of the first, second, and third reels 21a, 21b, and 21c. The first, second, and third reels 21a, 21b, and 21c are fixed to the drive shaft of the stepping motor 80, respectively, and the symbol drive control unit 82 controls the rotation of each of the reels 21a to 21c by controlling the drive of each stepping motor 80. To control. Each stepping motor 80 is supplied with a DC current of 24 V from the power supply unit 94, and the stepping motor 80 is driven based on this supplied current.

  When the first, second, and third stop buttons 40, 41, and 42 are pressed, a stop signal for stopping the reel drive is input to the CPU 61. The rotation of the reels 21a to 21c is started by the operation of the start lever 38. When the rotation of the reels 21a to 21c reaches a certain speed, the operation of the stop buttons 40 to 42 becomes effective.

  On the outer periphery of each reel 21a-21c, "Watermelon", "7", "BAR", "Bell", "Cherry", "Replay Symbol", etc. are arranged, and the symbol corresponding to the winning combination is the winning line When the display is stopped, the winning combination determining unit controls the winning combination. For example, when “7-7-7” is stopped and displayed on the winning line, the winning combination determining unit 78 determines the big win, and when “BAR-BAR-BAR” is stopped and displayed on the winning line, the small win is received. It is determined. When the jackpot is displayed on the winning line, in addition to paying out a predetermined number of medals, a big bonus (BB) is generated and 30 special games can be played, for example. When the small win is displayed on the winning line, in addition to paying out a predetermined number of medals, a regular bonus (RB) is generated and a predetermined number of special games can be played.

  The hopper device 50 pays out the number of medals corresponding to the winning combination determined by the winning combination determining unit 78 to the medal tray 45 as a bonus. A hopper motor 50 a is provided in the hopper device 50, and the hopper motor 50 a is driven by a CPU 61. The CPU 61 controls the hopper motor 50 a based on the payout data read from the payout table 69 stored in the ROM 62. Drive. The hopper motor 50a is supplied with a direct current of 24 V, for example, and operates in response to a drive command from the CPU 61 based on this supplied current.

  The setting change device 55 is provided with a setting change key cylinder 55a, a power switch 55b, a set value change button 55c, and a setting change board 55e that transmits a signal to the control unit 60 when these are operated. When the setting change key 55d is inserted into the setting change key cylinder 55a, is rotated 90 degrees clockwise and is keyed from the OFF position to the ON position, and the power switch 55b is turned ON, the setting change board 55e is accordingly turned on. A setting change signal is input to the control unit 60. As a result, the set value can be changed by pressing the set value change button 55c. In the slot machine 3 of the present invention, the CPU 61 that has received the setting change signal operates the start lever 38 to confirm the set value determination signal sent from the start switch sensor 76, and the confirmation operation control provided in the control unit 60. A command is sent to the unit 79 to disable the function for determining the set value by the start lever 38. The function of determining the set value of the invalidated start lever 38 is validated by performing a predetermined release operation on the release button 56.

  When the set value change button 55c is pressed, a set value signal is input to the control unit 60 via the setting change board 55e correspondingly, and the set value displayed on the 7-segment display device 25 is switched. For example, when the setting change key cylinder 55a is turned ON and the power switch 55b is turned ON, if the current setting value is “1”, for example, “1” is displayed on the 7-segment display device 25, and the setting value change button 55c The set values displayed according to the operation are switched in order of “2”, “3”, “4”, “5”, “6”.

  To confirm the set value, the start lever 38 is operated, but even if the start lever 38 is operated, the set value confirm signal from the start switch sensor 76 is held by the confirm operation control unit 79 and the function for confirming the set value is disabled. Therefore, it is necessary to activate the function of the start lever 38 by operating the release button 56. The release button 56 is a normal push button switch, which is turned on when pressed with a finger or the like and turned off when the finger is released. In order to validate the function of the start lever 38, the release button 56 is operated by a predetermined release operation. For example, in this embodiment, the setting value change button 55c is operated to set a setting value, and then the operation of turning the release button 56 on and off seven times within 5 seconds is set as a predetermined release operation. . When the release operation is performed, the determination unit 65 determines whether the release operation is a predetermined release operation according to the signal. If the determination unit 65 determines that the predetermined release operation is not performed, the setting value fixing function of the start lever 38 remains disabled. In order to solve this state, the power switch 55b is turned off again, the setting change operation is performed again from the beginning, and a predetermined release operation is performed.

  When the determination unit 65 determines that a predetermined release operation has been performed, the set value confirmation signal of the start lever 38 that has been held is received by the confirmation operation control unit 79, and the setting value confirmation function of the start lever 38 is activated. The set value is confirmed. Then, the setting value displayed on the 7-segment display device 25 is confirmed, and the setting value displayed on the 7-segment display device 25 is newly set by returning the setting change key 55d from the ON position to the OFF position.

  When the set value is newly set, any of the first to sixth winning tables 63a to 63f corresponding to the newly set value is read from the ROM 62, and the game is played with the winning probability corresponding to the set value. Be controlled. When the setting change key cylinder 55a is not operated to the ON position, no setting value is displayed on the 7-segment display device 25 even when the power switch 55b is ON, and the setting value change button 55c is pressed. However, the set value is not switched. Further, in this embodiment, there are six set values “1” to “6” that can be selected, and each set value is associated with the first to sixth winning tables 63a to 63f. The number of corresponding winning tables is not limited to this, and may be more or less.

  The operation of the slot machine 3 configured as described above will be described with reference to the flowchart of FIG. The game hall manager changes the winning probability setting by operating the setting changing device 55 outside the business hours of the game hall. In order to change the setting, after the lower door 17 is unlocked, the power switch 55b provided in the setting change device 55 is temporarily turned off. Then, the setting change key 55d is inserted into the setting change key cylinder 55a and turned from the OFF position to the ON position, and the power switch 55b is turned ON. At this time, the CPU 61 can accept the change of the set value by the set value change button 55c. At the same time, the set value confirmation signal from the start switch sensor 76 is held by the confirmation operation control unit 79, and the set value of the start lever 38 is set. Control is performed so that the confirmation function is invalidated.

  The manager of the game hall operates the set value change button 55c to change the set value while displaying the set value on the 7-segment display device 25. When the set value is determined, the release button 56 is subsequently turned ON / OFF 7 times within 5 seconds. As a result, the confirmation operation control unit 79 receives the set value confirmation signal from the start switch sensor 76, and the confirmation operation function of the start lever 38 is validated. The administrator operates the start lever 38 to determine the changed setting value. The setting change key 55d inserted in the setting change key cylinder 55a is rotated from the ON position to the OFF position and extracted, the setting change operation is terminated, and the lower door 17 is closed. The setting change mode ends and the game mode is entered. If the release operation is not performed as prescribed, the setting value confirmation function of the start lever 38 remains disabled, and the power switch 55b is turned off again to perform the setting change operation, so that the release button 56 is correctly operated. I need to start over.

  When starting the game, the player inserts a medal from the medal insertion slot 43. The medal passes through the selector and is sent to the medal storage tank 52. The selector detects whether or not the medal is appropriate. When the medals are inappropriate, the medals are discharged from the medal payout port 44 to the tray 45. If the medal is appropriate, the medal passes through the inserted medal sensor 75 provided at the rear end of the selector, receives the signal from the inserted medal sensor 75, and the CPU 61 counts the number of medals inserted.

  After inserting the required number of medals for one game, the bet number is set by operating the one bet button 35 or the MAX bet button 36, and the start lever 38 is operated to start the rotation of the reels 21a to 21c. To do. At the same time, the electronic lottery unit 77 and the winning combination determining unit 78 draw the winning combination. The player operates the stop buttons 40, 41, and 42 to stop the reels 21a to 21c, and repeats the game while expecting that a predetermined pattern is stopped and displayed on the winning line.

  By the way, a player plays a game in order to acquire many medals, and for this purpose, there are players who illegally attempt to acquire many medals by changing the winning probability setting. For example, a player who intends to cheat while playing a game illegally opens the lower door 17 or inserts a foreign object such as a wire from a gap in the machine body or the medal slot 43 to cheat the setting change device 55. To change the setting. For example, the power switch 55b is operated with a foreign object such as a wire to operate the setting change key cylinder 55a, or the corresponding part of the setting change board 55e is short-circuited, as if the power switch 55b or the setting change key cylinder 55a is operated. Try to change the setting as if it were. Then, at this stage, the setting change board 55e transmits a setting change signal to the CPU 61 of the control unit 60.

  Receiving the setting change signal, the CPU 61 issues a command to hold the setting value confirmation signal transmitted from the start switch sensor 76 in the confirmation operation control unit 79 and invalidates the setting value confirmation function of the start lever 38. Although the set value can be changed by operating the set value change button 55c, the set value confirmation signal by the start lever 38 is suspended, and the set value cannot be confirmed. A player who is cheating further cheats to activate the function of the start lever 38, but after setting the set value by operating the set value change button 55c, it is canceled by a predetermined canceling operation. Unless the button 56 is operated, the set value confirmation function of the start lever 38 is not validated. For example, even if the presence of the release button 56 is found and operated, the predetermined release operation is ignorant, so the operation is performed randomly.

  If the release operation for enabling the set value confirming function of the start lever 38 is not performed in a predetermined manner, the set value is not confirmed because the set value confirming signal remains on hold. Even if the player turns off the power switch 55b and attempts to change the setting again in an attempt to solve this problem, the setting value confirmation function of the start lever 38 is provided unless the predetermined release operation of the release button 56 is performed. Since the invalidated cycle is entered, the set value cannot be determined, and therefore the damage to the playground can be minimized.

  A second embodiment of the present invention will be described based on the flow of FIG. It is to be noted that the operation until the setting change operation is performed and the function for determining the set value of the start lever 38 is disabled is the same as in the previous embodiment, and the description thereof is omitted. Even if the player performs the setting change operation illegally and operates the setting value change button 55c, the setting change key 55d is returned from the ON position to the OFF position in the setting change key cylinder 55a, and the release operation is performed. Is not a predetermined release operation, the game start signal transmitted from the start switch sensor 76 by operating when the game of the start lever 38 is started is also held, and the game start function of the start lever 38 is also invalidated. When both the setting value confirmation function of the start lever 38 and the game start function are disabled, the setting change operation must be performed again after the power switch 55b is turned off again. Since the player operates the release button 56 unnecessarily, the player cannot perform a predetermined release operation. Therefore, if the set value cannot be determined by the start lever 38, the game cannot be started. Therefore, fraudulent acts can be prevented and damage to the playground can be minimized.

  As described above, according to the slot machine of the present invention, when a setting value change is made in the setting change device as the setting change means, the set value confirmation signal transmitted from the start switch sensor is suspended and for the confirmation operation. The setting value confirmation function of the start lever is disabled, so the setting value cannot be confirmed. In addition, if the release button for enabling the function for determining the set value of the start lever is not operated by a predetermined release operation, the function for determining the set value of the start lever remains disabled and the game of the start lever The game cannot be started by disabling the start function. Therefore, it is possible not only to prevent fraud but also to prevent the game from being lost because the game cannot be performed.

  In the above embodiment, the function for determining the set value of the start lever cannot be enabled unless the release operation is correctly performed, and the method for disabling the function for starting the game has been described. If the function for confirming the value remains disabled, the setting change mode will not be terminated, and medals will not be accepted at the medal slot, or the game mode such as disabling the bet button operation will be It is also possible to disable all functions for starting so that the game mode cannot be entered. Alternatively, for example, if the release operation is not correct, the slot machine may be turned off when the start lever is operated to confirm the set value.

  In the above embodiment, the setting value confirmation function of the start lever is disabled when the setting change key cylinder is operated and the power switch is turned on. However, when the setting change key cylinder is operated. May be invalidated, and further, it may be invalidated when a setting change is attempted within the business hours of the game hall. In addition, as a method of invalidating the setting value confirmation function or game start function of the start lever, the setting value confirmation signal or game start signal transmitted from the start switch sensor when the start lever is operated is ignored. It may not be possible to transmit the value confirmation signal or the game start signal itself.

  In addition, as a predetermined release operation for operating the release button, the method for repeating ON / OFF of the release button 7 times within 5 seconds after the set value change button has been operated has been described. If the rear release button is not operated and the start lever is operated, it is possible that the predetermined release operation is not performed. And it is not this limitation if it is the operation method which a player cannot notice easily. For example, a means for registering and recognizing a password or fingerprint may be provided in advance, and the release button may be operable only when the password or fingerprint matches.

  Furthermore, the release button does not have to be provided on the main body of the gaming machine, and can be released only at a position that cannot be easily found by the player, for example, a hall computer that monitors the gaming state of the slot machine.
