  By the way, in order to acquire more game media, some players try to acquire the game media using illegal means. For example, a gaming machine incorporates a CPU (Central Processing Unit) and a ROM (Read Only Memory) in advance by the manufacturer, and the gaming machine controls the game by the CPU based on data stored in the ROM. May be exchanged by the player and game media may be illegally paid out.

  Further, as a method that is less likely to be found than a method of replacing the ROM, there is a method of illegally changing the winning probability set in the gaming machine and paying out a large amount of gaming media. For example, when the set values are prepared in six stages from “1” to “6”, a winning table is prepared corresponding to each set value, and the display screen is displayed according to the ON of the setting change key. The current setting value is displayed among “1” to “6”, and after the setting value is newly selected and the setting change key is turned off, the game is played based on the winning table corresponding to the newly selected setting value. The winning table used by illegally changing this set value can be changed to a winning table that can be easily won by a big bonus (BB), regular bonus (RB), or the like. In this method of changing the winning probability, the suspicious operation of the player is difficult to distinguish compared with the method of exchanging the ROM, so that the game hall manager may not notice the setting change. 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.

  The setting change program 67 stored in the ROM 62 is a program used when changing the winning probability, and the power is supplied in a state where the setting change key inserted into the setting change key cylinder 55a is turned from the off position to the on position. It is read when the switch 55b is turned on. When the setting change key is turned from the on position to the off position and pulled out of 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 inside 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 1 bet button 35 and the MAX bet button 36 are pressed, a pressing signal is input to the CPU 61. The CPU 61 determines the number of 1 to 3 medals inserted prior to the start of the game in response to a detection signal from the insertion medal sensor 75 or when one of the 1 bet button 35 or the MAX bet button 36 is pressed. The number of winning lines is determined based on the input pressure signal. Further, the bet number of medals inserted at the start of the game is added up and counted by a counter provided in the CPU 61.

  The start switch sensor 76 is turned on when the start lever 38 is operated, and inputs a game start signal to the CPU 61. The CPU 61 that has received the game start signal rotates the first, second, and third reels 21 a, 21 b, and 21 c based on the game execution program stored in the ROM 62, and operates the electronic lottery unit 77.

  The control unit 60 is provided with an electronic lottery unit 77 and a winning combination determining unit 78. The electronic lottery unit 77 includes a random number generation unit and a random number extraction unit, and extracts one random value every time the 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 the winning combination determining unit 78 is a loser or a plurality of types of winning combinations.

  Driving and stopping control of the first, second, and third reels 21a, 21b, and 21c is performed by the symbol drive control unit 79. The first, second, and third reels 21a, 21b, and 21c are respectively fixed to the drive shaft of the stepping motor 80, and the symbol drive control unit 79 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, and the stepping motor 80 is driven based on this supplied current.

  The CPU 61 is provided with a pulse counter for each stepping motor 80 and counts the number of drive pulses supplied to each stepping motor 80. When the reset signal is input from the photo sensor 82, the count value of the corresponding pulse counter is cleared. Thus, each pulse counter monitors the driving of each reel 21a-21c based on the number of drive pulses corresponding to the rotation angle within one rotation of each reel 21a-21c.

  The symbol table 68 stored in the ROM 62 includes a symbol code indicating the number of drive pulses corresponding to the rotation angle from the reference position of each reel 21a to 21c and the symbols arranged on the reels 21a to 21c at a constant pitch. Are associated with each other. As a result, by counting the count value of the pulse counter for each reel, it is possible to identify which symbol has moved on a predetermined winning line, and how much the reel is rotated to achieve a predetermined symbol. It can be predicted whether it will move on the winning line.

  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.

  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. The setting change key cylinder 55a and the power switch 55b constitute changeable means 55d that enables the operation of the setting value change button 55c. The setting change key is inserted into the setting change key cylinder 55a and turned on from the off position. When the key is operated to the position and the power switch 55b is turned on, a setting change signal is input from the setting change board 55e to the control unit 60 accordingly. As a result, the set value can be changed by pressing the set value change button 55c. A setting change signal transmitted from the setting change board 55e when the power switch 55b is turned on is further transmitted from the control unit 60 to the hall computer 7 via the communication I / F 92.

  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 15 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”. The set value displayed on the 7-segment display device 25 is confirmed according to the operation of the start lever 38, and the set value displayed on the 7-segment display device 25 is newly set by returning the setting change key from the on position to the off position. Is done. Thereafter, any one 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 controlled with the winning probability corresponding to the set value. 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 communication I / F 92 is connected to the hall computer 7 via the communication cable 5 and exchanges various data with the hall computer 7. For example, the setting change signal when starting the change of the setting value and the setting value signal when the setting value is changed are recognized by the control unit 60, and the communication I / F 92 responds to the setting change signal and the setting value signal. Is sent to the hall computer 7.

  FIG. 5 is a block diagram schematically showing the electrical configuration of the hall computer 7. The hall computer 7 includes a central processing unit 100, a RAM 102, a hard disk 104, a display control unit 106, an alarm control unit (an illegal signal transmission unit of the present invention) 108, an input interface (hereinafter referred to as input I / F) 110, communication Interface (hereinafter referred to as “communication I / F”) 112, external interface (hereinafter referred to as “external I / F”) 114, fraud determination unit 116 as a determination means, and the gaming machine is specified when fraud is performed. A game machine specifying unit 117 and a time measuring circuit 118 are provided as specifying means.

  The hard disk 104 stores the operating system of the hall computer 7 and various application programs, and these programs are read and executed by the central processing unit 100. When the program is executed, the RAM 102 is appropriately used so that the program is executed smoothly. Operating devices such as a keyboard 120 and a mouse 122 are connected to the input I / F 110, and a signal is input from the input I / F 110 to the central processing unit 100 in accordance with the operation of the key board 120 and the mouse 122. For example, an information recording device or printer having a connector conforming to the USB standard can be connected to the external I / F 114, and management information or the like is recorded in the external storage device or printer via the external I / F 114. Or can be printed.

  The display screen 7a is controlled by the display control unit 106, and displays various videos according to the operation of the administrator. The alarm control unit 108 controls the hall computer 7 and the alarm 126 of each slot machine 3, and issues a warning to the outside by the alarm 126 when alerting the administrator or when an abnormality occurs. The notification device 126 is composed of, for example, red and blue LEDs, and the notification device control unit 108 has a program for turning on / flashing the red LED and blue LED of the notification device 126 (an illegal signal of the present invention). It is remembered. If any abnormality occurs in the slot machine 3, this is communicated to the hall computer 7 via the communication cable 5, and the alarm control unit 108 outputs an illegal signal based on the command of the central processing unit 100, and the red color of the alarm 126. Alternatively, control is performed so that the blue LED or the LEDs of both colors are lit and blinked. The alarm 126 may be a so-called patrol light that rotates as the LED emits light.

  The fraud determination unit 116 determines whether the setting change is illegal based on the setting change signal input from the slot machine 3. In fraud determination unit 116, a time zone in which the setting change is allowed and a time zone in which the setting change is prohibited are determined in advance based on a timing signal from timing circuit 118, and other than the time zone in which the setting change is allowed. If a setting change signal is received, it is determined to be illegal. As a time zone in which it is determined that the setting change is illegal, for example, a game hall business time zone is determined in advance, and it is not determined to be illegal in other time zones. Normally, the setting is not changed during the business hours of the amusement hall. For this reason, when the setting change signal is input during the business hours, the fraud determination unit 116 determines that the setting is illegal, so that the illegal setting change is ensured. You can recognize that is going to be done. Based on the identification number tag included in the setting change signal determined to be illegal by the fraud determination unit 116, the illegal slot machine determined to be illegal by the gaming machine specifying unit 117 is identified, and the slot machine in which fraud is not performed is identified. Identify at least one normal slot machine for each island. The normal slot machine can be identified by randomly selecting each island from the identification number tag excluding the identification number tag of the illegal slot machine determined to be illegal, or identifying the illegal slot machine. A method of selecting a slot machine having an identification number tag obtained by adding a certain numerical value to the number tag may be used. This selection method may be set in advance as a program in the gaming machine specifying unit 117 so that the slot machine 3 that lights / flashes the alarm device 126 can be changed every day according to a parameter. It is also possible to set in advance an island at a position that can be easily monitored by the game hall manager and select a normal slot machine included in the island. In this way, it is difficult for the player to predict which slot machine's alarm 126 will be lit / flashed, making it difficult to perform fraud.

  The communication cable 5 is connected to the communication I / F 92 of the slot machine 3 and the communication I / F 112 of the hall computer 7, and data is input / output between the slot machine 3 and the hall computer 7. From the slot machine 3, the jackpot information indicating the number of jackpots, the jackpot information indicating the number of jackpots, an abnormal signal in the case of fraud is input to the hall computer 7 via the communication cable 5.

  When a setting change signal is input from the slot machine 3 and this is determined to be illegal by the fraud determination unit 116, the central processing unit 100 identifies the illegal slot machine in the gaming machine identification unit 117 and a normal slot for each island. At least one of the machines 3 is selected. Alternatively, at least one machine is selected from normal slot machines 3 included in an island set in advance by a game hall manager. Then, an unauthorized signal is transmitted from the alarm control unit 108 to the selected slot machine 3 and the alarm 126 of the hall computer 7. The hall computer 7 that has received the illegal signal and the alarm 126 of the slot machine 3 notify that the illegal signal has been received.

  The operation of the present invention will be described with reference to the flowchart of FIG. When changing the setting value in the slot machine 3, the lock 28 is unlocked, the lower door 17 is opened, and the setting change key is inserted into the setting change key cylinder 55a provided in the setting change device 55 and turned on. When the setting change key cylinder 55a is turned on and the power switch 55b is turned on, the current setting value is displayed on the 7-segment display device 25. At the same time, a setting change signal is transmitted from the slot machine 3 to the hall computer 7. The set value is changed by pressing the set value change button 55c and performing a predetermined setting change operation. To confirm the set value, the start lever 38 is operated.

  The hall computer 7 receives a setting change signal from each slot machine 3 according to the setting change operation. The hall computer 7 determines whether or not this setting change is illegal based on the setting change signal from each slot machine 3. If it is determined that the setting change is illegal, the slot machine 3 in which the illegal setting change is made is determined. For example, the hall computer 7 determines that the setting change signal is invalid when it is input within business hours, and determines that it is valid when the setting change signal is input outside business hours, The illegal slot machine 3 is identified from the identification number tag included in the setting change signal determined to be illegal among the setting change signals input from the respective slot machines 3. At the same time, at least one slot machine 3 is selected from normal slot machines for each island. The hall computer 7 causes the alarm control unit 108 to generate, for example, an illegal signal that causes the red LED of the alarm 126 to blink, causing the alarm 126 of the hall computer 7 itself to blink red and the island via the communication I / F 112. An illegal signal is transmitted to at least one normal slot machine 3 selected every time, and the indicator 126 blinks in red. When an island including a slot machine to be notified by the game hall manager is set in advance, an illegal signal is transmitted to at least one normal slot machine on the island, and the alarm 126 of the slot machine 3 Flashes red. Therefore, the manager of the game hall can confirm from the arbitrary position in the game hall that the illegal act has been performed. The hall computer 7 receives the setting change signal before the setting change button 55c is operated. Therefore, if the setting change signal is illegal, the hall computer 7 can transmit the illegal signal before the setting value is changed. , Damage can be minimized.

  FIG. 7 is a flowchart showing a second embodiment of the present invention. When the setting is changed in the business hours in the slot machine 3, an illegal slot machine in which an illegal act has been performed is specified by the hall computer 7, and at least one normal slot machine is selected for each island. Then, in the alarm controller 108, an alarm signal that causes the alarm 126 provided in the hall computer 7 itself and the alarm device 126 of the selected normal slot machine to blink in blue, and the alarm device 126 of the specified unauthorized slot machine are identified. And a specific illegal signal that flashes red. The illegal signal and the specific illegal signal are transmitted from the communication I / F 112 to the selected normal slot machine and the specified illegal slot machine via the communication cable 5, and the alarm 126 of the hall computer 7 and the normal slot machine are notified. The indicator 126 flashes blue and only the illegal slot machine alarm 126 flashes red. As a result, it is possible to easily confirm that the illegal act has been performed and the illegal slot machine itself from an arbitrary position in the game hall.

  As described above, in the game management system of the present invention, since the setting change signal is transmitted when the setting change key cylinder 55a is turned on and the power switch 55b is turned on, before the setting change button 55c is operated. Since the misconduct is judged and the slot machine where the misconduct is made is distinguished and notified, the slot machine and the misconducted player who have been misconducted can be identified quickly, and the damage caused by the misconduct is minimized. Can be prevented as much as possible.

  In the above embodiment, the alarm 126 and the alarm 126 of the normal slot machine blink in blue, the illegal slot machine alarm 126 flashes in red, and the illegal slot machine is promptly identified. Although it is confirmed, the type of color and the method of blinking are not limited as long as it is a method that can quickly confirm that the fraud has been made and the unauthorized slot machine. In addition, although the alarm is a warning light in which the LED is turned on / flashing, a speaker that emits a warning by sound may be used. In such a case, a speaker is provided instead of the alarm 126 to issue a warning. In addition, both a warning light and a speaker may be provided as an alarm so as to issue a warning by both light and sound. These alarms may also serve as a liquid crystal display device 23 or a speaker provided in advance in the slot machine in order to enhance the fun of the game.

It is a perspective view which shows the slot machine of this invention. FIG. 5 is a partial cross-sectional view showing the inside of the slot machine cut into parts. It is the enlarged view to which the setting change apparatus provided in the inside of a slot machine and its periphery were expanded. FIG. 4 is a block diagram schematically showing an electrical configuration of the slot machine. It is the block diagram which showed schematically the electric constitution of the hall computer. It is a flowchart which shows the effect | action of this invention. It is a flowchart which shows the effect | action of the 2nd Example of this invention.
