  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 value is changed by a method of operating the setting change operation unit or a method of inserting a wire or the like from a gap in the machine body, a medal insertion slot, a medal discharge slot or the like to short-circuit the power supply device. 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.

To stop.

  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 18 is unlocked and the lower door 17 is opened, and the setting change key is inserted into the setting change key cylinder 55 a 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. When the start lever 38 is operated, a setting confirmation signal is transmitted from the slot machine 3 to the hall computer 7.

  The hall computer 7 receives a setting change signal from each slot machine 3 according to a setting change operation, and identifies the slot machine 3 that has output the setting change signal. Further, the hall computer 7 determines whether or not this setting change is illegal based on the setting change signal from each slot machine 3, and when it is determined that the setting change is illegal, the illegal setting change is performed. You may make it index the slot machine 3 passed. For example, the hall computer 7 determines that the setting change signal is invalid when the setting change signal is input during business hours, and determines that the setting change signal 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 slot machine 3. The hall computer 7 sends a supply stop command signal to the power supply control device 9 in order to stop the power supply to the slot machines 3 other than the specified illegal slot machine 3. The power supply control device 9 stops the supply of AC 24V AC current to the slot machine 3 designated by the supply stop command signal. In the slot machine 3, the supply of the 24V DC current and the 5V DC current is stopped in response to the supply stop of the AC 24V AC current, whereby the driving of each part of the slot machine 3 is stopped and the game cannot be continued. In this case, in order to immediately return the power supply so as not to be deceived, it is preferable that the power supply is not recovered unless a predetermined time elapses after the power supply is stopped.

  Since the setting change signal is transmitted in accordance with the operation of the changeable means 55d at the stage before the setting change button 55c is operated, the power supply to the normal slot machine 3 is also stopped at that time and can be changed. It is possible to quickly identify a slot machine that can be cheated by a player around the slot machine 3 and an administrator of the game hall, and a player who may act cheating.

  When an illegal slot machine 3 in which an illegal act has been performed is found, the manager of the game hall returns to a state in which the setting value of the illegal slot machine 3 has not been changed, and then performs an error canceling operation. When an error release button (not shown) or the like is operated, a return setting confirmation signal is transmitted to the hall computer 7. The hall computer 7 that has received the return setting confirmation signal from the found illegal slot machine 3 sends a supply return command signal to the power supply control device 9 to restore power supply to the slot machines 3 other than the found illegal slot machine 3. Send it out. The power supply control device 9 returns the supply of AC 24V AC current to the slot machine 3 designated by the supply return command signal.

  The control unit 60 of each slot machine 3 is provided with a game storage unit (storage unit and return unit of the present invention) 65 composed of a RAM 65b and a CPU 65a. The CPU 65a has a control function of reading the latest gaming state stored in the RAM 65b while storing the RAM 65b while constantly rewriting the gaming state change during the game. Further, even if the supply of power is stopped for some reason, the CPU 65a stores the gaming state at that time in the RAM 65b, and when the power supply is resumed, the gaming state at the time when the power supply is stopped is restored. A control function is also provided.

  Therefore, even when the slot machine 3 is specified by the setting change signal and the power supply to the slot machines 3 other than the specified slot machine 3 is stopped, the game at the time when the power supply is stopped by the CPU 65a of the game storage unit 65. The state is stored and saved in the RAM 65b, and when the power supply is resumed, the game state at the time when the power supply is stopped by the CPU 65a is read from the RAM 65b. When the power supply is resumed, the player can resume the game from the gaming state at the time when the power supply is stopped.

  In the above embodiment, the power supply control device 9 stops or returns the supply of the AC current, so that the slot machine 3 cannot or continues the game. However, the method of stopping or returning the slot machine Is not limited to this. For example, the function of the slot machine may be stopped or returned by stopping or returning the function of the power supply unit provided in the slot machine. The supply stop command signal or supply return command signal from the hall computer is input to the slot machine, and the power supply unit of the slot machine receives the DC current in response to the input of the supply stop command signal or the supply return command signal. Stop or restore generation. As a result, each part of the slot machine is stopped or returned so that the game cannot be continued or returned. In this way, the slot machine can be stopped or returned by controlling the power supply unit in the slot machine with the hall computer.

  Further, although the game storage unit is provided in the control unit independently of the main CPU and the main RAM, the main CPU and the main RAM may have the function of the game storage unit.
