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 shop. More specifically, the present invention relates to a gaming machine provided with a non-gameable means that makes it impossible to play a game in the gaming machine when an illegal act is performed in the gaming machine.

  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 general, a game room is provided with a game medium lending device that lends a dedicated game medium to be used in a gaming machine, and a player inserts a bill or a prepaid card into the game medium lending device to obtain an amount necessary for the game. Receive a loan of the corresponding game media. For example, in the case of a slot machine, the player inserts a medal or pachinko ball as a rented game medium into the slot machine, and then places a symbol of a reel that rotates in accordance with the game start operation on the winning line. The game is played with the aim of acquiring game media to be paid out as a bonus when the predetermined symbols are arranged in a stopped display. 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 more game media.

  In the slot machine, there are two methods for inserting medals, one of which is to insert the required number of medals from the medal slot provided on the front surface of the slot machine each time a game is played. The other method is to accumulate a predetermined number of medals in the slot machine and credit it (electrically store), and use this as a source to operate the bet buttons provided on the front of the slot machine. This is a method of automatically inserting.

  The player inserts three medals required for one game from the medal slot and operates the start lever. When the start lever is operated, the three reels start to rotate, and a lottery means performs a lottery. The winning lottery (winning) by the lottery means that a winning symbol is awarded when a predetermined symbol is lined up on the winning line when the rotating reel is stopped, and a predetermined number of medals corresponding to the winning symbol. Is paid out to the tray as a bonus. When the credit function is working, a part of a predetermined number of medals to be paid out as a bonus is credited inside the slot machine without being paid out to the tray.

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, there is a method of illegally changing a set winning probability and illegally paying out medals as game media. Specifically, a player who aims to gain profits illegally operates to open a hole in the front door provided on the front of the gaming machine or to change the setting by forcibly opening the front door The setting is changed by operating the setting change operation unit, or by inserting a wire from the gap between the gaming machine body and the front door, the medal slot, and the medal outlet to short-circuit the power supply unit etc. The value is changed. 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. Patent Document 2 proposes a method for preventing fraud by providing a medal selector for detecting whether or not the inserted medal is legitimate.
JP 2004-135844 A Japanese Patent Laid-Open No. 2004-166806

  However, in the proposal described in the above-mentioned patent document, a game can be played even if the illegal act can be prevented, so that the player who tried the illegal act can play the game as it is.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to propose a gaming machine provided with a non-gameable means that makes it impossible to play a game in the gaming machine when an illegal act is performed.

  In order to achieve the above object, in the present invention, a medal slot for inserting medals, a storage tank for storing medals, and a medal inserted from the medal slot in communication with the medal slot are stored. In a gaming machine provided with an inserted medal passage leading to a tank, an unauthorized determination means for determining whether fraud has been performed, a medal flow stop means for stopping the flow of medals in the inserted medal path, and an unauthorized determination means And a medal flow control means for operating the medal flow stop means so as not to guide the medal inserted from the medal slot to the storage tank when it is determined that fraud has been made. And

  The medal flow stop means has a dam member that is displaceable between a projecting position that protrudes into the insertion medal passage and a retreat position that retracts, and when the dam member projects, the medal insertion port The medal inserted from the abutment against the dam member stops the flow down, and among the medals that have stopped flowing down, the rear end in the flow direction of the medal closest to the medal insertion port is inside the medal insertion port. And is stopped at a close position.

  Further, the credit means for detecting and electrically storing medals inserted from the medal slot, and when the fraud determination means determines that fraud has been made, the credit means electrically stores the medal. And a credit control means for deleting the number of medals.

  According to the gaming machine of the present invention, when an illegal act is performed, medals inserted from the medal insertion slot are clogged in the insertion medal passage, and medals located closest to the medal insertion slot among the clogged medals. Since the rear end of the flow direction at the inside of the medal slot is stopped and close to the medal slot, it can not be removed even if the clogged state of the medal can be seen, and the clogging of the medal is resolved. The player will call the game hall manager. Therefore, the manager of the game hall can catch an unauthorized player. In addition, since it is not possible to insert medals on a gaming machine that is still packed with medals, it is possible to prevent new players from starting the game and call the game hall manager to quickly eliminate clogging of medals. As a result, damage to the amusement hall can be minimized.

  In addition, if an illegal act is performed, the number of electrically stored medals is erased and a game using the stored medals cannot be started, so that the effect of the present invention is enhanced. .

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 medal sensor 75, a start switch sensor 76, a display control unit 90, a solenoid drive control unit (medal flow control means of the present invention) 91, a communication interface (hereinafter referred to as communication). I / F) 92, a credit control unit (credit control means of the present invention) 93, a power supply unit 94, and the like are provided.

  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 from the ON position, returned 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 of the medal selector 43b, and detects the appropriate medal 10 distributed by the medal selector 43b among the medals 10 inserted from the medal slot 43. A detection signal output from the inserted medal sensor 75 is input to the CPU 61, whereby the CPU 61 detects the number of inserted medals 10. In the slot machine 3 of the present embodiment, a credit in which a part of the number of medals inserted from the medal insertion slot 43 and a part of a predetermined number of medals 10 paid out as a bonus are electrically stored up to a specified number. Unit (credit means) 93a, which is counted by the credit control unit 93 and automatically credited up to a specified number. The credit control unit 93 also has a function of erasing credits of the present invention described later.

  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 detects the number of 1 to 3 medals 10 inserted prior to the start of the game, 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 is counted based on the pressing signal input accordingly, thereby determining the number of winning effective lines. Further, the number of bets placed on the medals 10 when the game is started is added up and counted by a counter (not shown) 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 21a, 21b, and 21c and activates the electronic lottery unit 77 based on the game execution program stored in the ROM 62.

  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 from the power supply unit 94, 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 effective line. It is possible to predict whether or not the vehicle will move on a predetermined winning active 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. 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 circumference of each reel 21a to 21c, "Watermelon", "7", "BAR", "Bell", "Cherry", "Replay Symbol", etc. are arranged, and the symbol corresponding to the winning combination is valid for winning When stopped on the line, 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 winning is determined. When the big win is displayed on the winning line, a big bonus (BB) is generated in addition to the payout of a predetermined number of medals 10, and for example, 30 special games can be played. When the small win is displayed on the winning line, a regular bonus (RB) is generated in addition to the payout of a predetermined number of medals 10, and a predetermined number of special games can be played.

  The hopper device 50 pays out the number of medals 10 corresponding to the winning combination determined by the winning combination determining unit 78 as a bonus. Since the credit function is working, up to a predetermined number, for example, 50 medals 10 are credited to the credit unit 93a of the slot machine 3, and the remaining number of medals are paid out to the tray 45. 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 turned 90 degrees clockwise and is operated from the OFF position to the ON position, and the power switch 55b is turned ON, the setting change board is accordingly received. A setting change signal is input to the control unit 60 from 55e. As a result, the set value can be changed by pressing the set value change button 55c.

  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”. 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 55d from the ON position to the OFF position. Is set. 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.

  FIG. 5A schematically shows the vicinity of the medal slot 43. FIG. 5B is a front sectional view thereof. As shown in FIG. 5, a medal blocker (medal flow stop means of the present invention) 46 is provided in the medal passage 43 a communicating with the medal slot 43. The medal blocker 46 is arranged between a solenoid 46a and an insertion position (protruding position) inserted (projected) in a direction perpendicular to an opening 43c provided on the wall surface of the medal passage 43a by the solenoid 46a and a retracted position retracted. And a metal rod-like stopper (damming member) 46b that is driven and displaced in a freely displaceable manner. The solenoid 46a and the stopper 46b are engaged by a fastening member (not shown) such as a screw, and the solenoid 46a is driven and controlled by a solenoid drive control unit 91. When the solenoid 46a is excited, the stopper 46b is displaced in a direction perpendicular to the wall surface of the medal passage 43a and inserted into the opening 43c. When the solenoid 46a is demagnetized, the stopper 46b is returned to the retracted position. When the stopper 46b is inserted into the opening 43c by the solenoid 46a, the medal 10 inserted from the medal slot 43 is prevented from flowing down by the stopper 46b, and the medal passage 43a is blocked.

  As shown in FIG. 5B, the opening 43c provided in the wall surface of the medal passage 43a has a circular shape, and the stopper 46b inserted into the opening 43c has a circular cross section whose diameter is just inserted into the opening 43c. It has become a stick. The center of the opening 43c is, for example, the center line of the flow trajectory of the medal 10 flowing down in the medal passage 43a (Note: in this embodiment, the medal 10 flows when the medal 10 flows down along the medal passage 43a). The center of 10 is defined as a trajectory drawn) and the medal insertion port 43 and the flow down from the contact point Q of the medal 10 and the stopper 46b when the medal 10 stops when the stopper 46b is inserted into the opening 43c. A distance L1 on the downflow trajectory centerline C to the intersection P with the trajectory centerline C is a distance corresponding to approximately three medals 10. More specifically, when the stopper 46 b is inserted, up to three medals 10 can be inserted from the medal insertion slot 43, and the distance L1 is the third medal 10 closest to the medal insertion slot 43 and the center line of the downflow trajectory. It is provided at a position slightly longer than the distance L2 on the flow path center line C from the intersection R with C to the contact point Q with the stopper 46b of the first medal 10 in contact with the stopper 46b. Note that the flow path of the medal 10 is not necessarily a straight line, and the position where the stopper 46b is inserted is not necessarily limited to the flow path center line C of the medal 10, and therefore, from the intersection R to the contact point Q. Is not necessarily an integral multiple of the diameter of the medal 10.

  When the stopper 46b is inserted into the opening 43c, up to three medals 10 inserted from the medal insertion slot 43 are blocked in the medal passage 43a, and the fourth or more cannot be inserted. Of the jammed medals 10, the medal 10 closest to the medal insertion slot 43, that is, the third medal 10, stops so that the rear end in the flow direction is located slightly inside the medal insertion slot 43. Therefore, the medal 10 can be visually recognized from the medal slot 43 but cannot be taken out. It should be noted that the distance L1 from the intersection point P to the contact point Q and the distance L2 from the intersection point R to the contact point Q are the same, that is, the rear end in the flow-down direction of the medal 10 stopped at the position closest to the medal insertion slot 43 is just the medal insertion. You may make it stop in the same position as the opening | mouth 43. FIG.

  On the other hand, the medal selector 43b determines whether or not the inserted medal 10 is an appropriate medal 10. If the medal 10 is inappropriate, the medal 10 is discharged from the medal payout outlet 44 to the tray 45 through the discharge passage (not shown) before reaching the storage tank 52, and the appropriate medal 10 passes the inserted medal sensor 75. And stored in the storage tank 52. A signal from the inserted medal sensor 75 is transmitted to the CPU 61, and the CPU 61 counts the number of medals.

  By the way, the setting change operation for setting the winning probability is normally performed outside the business hours by the manager of the game hall. In order to change the setting, after the lower door 17 is opened, the setting change key cylinder 55a, the power switch 55b, the set value change button 55c, etc. in the setting change device 55 are operated. The determination unit 65 determines whether the setting change is illegal based on the setting change signal and the timing signal from the timing circuit 66. In the timer circuit 66, 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, and the determination unit 65 outputs a setting change signal other than the time zone in which the CPU 61 is allowed to change the setting. If 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 business hours business hours are predetermined, and are not determined to be illegal outside the business hours. Normally, the setting is not changed during the business hours of the amusement hall. For this reason, when the setting change signal is input to the CPU 61 during the business hours, the determination unit 65 determines that the setting change is illegal. It is possible to reliably recognize that a setting change is about to be made.

  When the determination unit 65 determines that the setting change is illegal, the CPU 61 of the control unit 60 issues a command to the solenoid drive control unit 91 to excite the solenoid 46a of the medal blocker 46 provided in the medal passage 43a. The solenoid 46a displaces the stopper 46b in the direction perpendicular to the wall surface of the medal passage 43a and inserts it into the opening 43c. Since the position of the medal blocker 46 is provided at a distance of about three medals 10 from the medal slot 43, up to three medals 10 inserted from the medal slot 43 cannot be inserted. At the same time, the credit control unit 93 in the control unit 60 deletes the number of medals 10 credited. Therefore, the medal 10 cannot be inserted from the medal slot 43, and the credited medal 10 cannot be used, and the player cannot start the game.

  The operation of the slot machine 3 configured as described above will be described with reference to the flowchart of FIG. When starting the game, the player inserts the medal 10 through the medal slot 43. The medal 10 is sent to the storage tank 52 through the medal passage 43a. The medal selector 43b detects whether or not the medal 10 is appropriate. If the medal 10 is inappropriate, the medal 10 is discharged from the medal payout opening 44 to the tray 45 before reaching the storage tank 52. If the medal 10 is appropriate, the medal 10 passes the inserted medal sensor 75 provided at the rear end of the medal selector 43b, receives the signal from the inserted medal sensor 75, and determines the number of medals inserted by the CPU 61. Count.

  By the way, a player plays a game in order to obtain a lot of medals, but there are players who try to obtain a lot of medals 10 by performing various cheating acts for that purpose. In this embodiment, a case where a player attempts to change the setting illegally will be described as an example. For example, a player who tries to cheat while a game is being played operates the setting change device 55 by opening the lower door 15b or inserting a foreign object such as a wire from the gap of the machine body or the medal slot 43. And try to change the settings illegally. When the setting change device 55 is operated, the setting change board 55e transmits a setting change signal to the CPU 61 of the control unit 60.

  The CPU 61 confirms the time zone when the setting change signal is received by the timer circuit 66, and since the setting change signal is a signal received within the business hours, the determination unit 65 determines that the setting change is illegal. To do. The determination unit 65 sends a signal determined to be illegal to the CPU 61. Based on the signal from the determination unit 65, the CPU 61 sends a command to the solenoid drive control unit 91 to excite the solenoid 46a. At the same time, a command is sent to the credit control unit 93 to erase the number of medals 10 credited.

  The solenoid 46a displaces the stopper 46b in a direction perpendicular to the surface of the medal passage 43a and inserts it into the opening 43c. The player inserts the medal 10 through the medal insertion slot 43. Since the medal blocker 46 is located at a distance of about three medals 10 from the medal insertion slot 43, the medal 10 flows down from the medal insertion slot 43 as if it was inserted up to the second sheet. Eventually, the third piece will clog and stop flowing. Moreover, since the rear end of the third medal in the flow direction stops at a position slightly inside the medal slot 43, the player can see the medal 10 but cannot take it out from the medal slot 43. The player inevitably calls the game hall manager to clear the clogging of medals. At this stage, it is possible to catch a player who has committed fraud.

  On the other hand, when the medal 10 is clogged at the medal slot 43, the player presses the single bet button 35 or the MAX bet button 36 to start the game using the credited medal 10. However, since the number of medals credited at the time when it is determined that fraud has been made, the game cannot be started using the medals 10 that should have been credited.

  The slot machine 3 is connected to a hall computer (not shown) via the communication I / F 92, and constantly monitors the gaming state of the slot machine 3, and the determination unit 65 determines that the setting change is illegal and performs solenoid drive control. The slot machine 3 in which the solenoid 46a is actuated by the portion 91 and the game is disabled can be identified.

  The manager of the game hall goes to the slot machine 3 where the fraud is made, unlocks and opens the lower door 15b, and exposes the setting change device 55. The setting change device 55 is provided with a release button 56. The release button 56 is set, for example, when the power switch 55b is temporarily turned OFF, the dedicated key 55d is inserted into the setting change key cylinder 55a, rotated 90 degrees counterclockwise from the OFF position, and the power switch 55b is turned ON. A signal is transmitted from the change board 55 e to the control unit 60, and the CPU 61 is controlled so as to be able to receive a signal from the release button 56. When the release button 56 is pressed in this state, a release signal is transmitted from the setting change board 55e, and the CPU 61 sends a command to the solenoid drive controller 91 to demagnetize the solenoid 46a. The game hall administrator inserts four or more medals 10 from the medal insertion slot 43, the medal 10 can be inserted, and the fourth and subsequent medals 10 are credited and the number of medals 10 credited is correct. After confirming that the setting is displayed, the setting change key 55d is rotated 90 degrees clockwise to return to the OFF state, and the setting change key 55d is removed from the setting change key cylinder 55a. The game of the slot machine 3 can be started by closing and locking the lower door 15b.

  As described above, according to the slot machine according to the present invention, when an illegal act is performed, the medals inserted from the medal slot become clogged and the game becomes impossible and the clogged medals can be visually recognized. Can not be removed, the fraudulent player can catch the fraudulent player by calling the game hall manager to resolve the clogging of medals, thus minimizing the damage of the game hall be able to. Also, even if a new player tries to play a game with a slot machine that has been filled with medals, the medals cannot be inserted, so the game cannot be started, and in this case, the manager of the game hall will be called, The effect of the present invention will be enhanced.

  And since the number of medals credited at the time when fraud is determined, the game cannot be started using the credited medals, and the effect of the present invention is further enhanced.

  In the above embodiment, the medal blocker is provided at a position approximately three distances from the medal insertion slot so that the medal is clogged at the medal insertion slot when an illegal act is performed. It is not limited to one minute, it may be one or more than three, and the rear end of the medal that is clogged when the medal blocker is activated is slightly inside the medal slot or the same position as the medal slot It is good to set it to come. In other words, if the player can clog the medals that can be visually recognized but cannot be removed, the number of medals to be clogged and the clogging positions are limited to the example described in this embodiment. is not.

  In addition, as an example of the medal flow stop means, the medal blocker in which a rod-like stopper is inserted by a solenoid in a direction perpendicular to the wall surface of the medal passage has been described. However, the stopper may be inserted from either the upper or lower direction of the medal passage. . Further, as long as the medal flow is stopped, the shutter is not limited to the rod-shaped stopper, and may be a flat shutter.

  Further, the credit is erased when the fraud is made, but this timing may be erased when the bet button is pressed after the fraudulent act is performed. In this way, since the display of the number of credited medals remains even if a medal clogging occurs at the medal slot according to the determination of fraud, the player can play with the credited medals. Operate the bet button to start. Since the credit is erased at that time, it is possible to attract the player in front of the slot machine, such as calling the game hall manager feeling suspicious.

  In addition, the player's fraudulent act is an act of changing the setting within the business hours, but this is not limited to this, and the fraudulent act is performed when the lower door is opened or the power switch is turned off during the business hours. You may judge.

  Then, as a method of canceling the game disable means, a method has been described in which a release button is provided at the position of the setting change device, and a dedicated key is inserted into the setting change key cylinder and rotated 90 degrees counterclockwise to turn on the power switch. However, this is not the case as long as it is a method that prevents a player who has committed fraud from being released 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. Anyway. By doing in this way, it is possible to prevent the unauthorized game means from being illegally released as part of the illegal act.

  Further, in the above-described embodiment, the present invention has been described by taking a slot machine using medals as a game medium as an example. However, the present invention can also be applied to a slot machine using pachinko balls. In addition to slot machines, pachinko machines installed in amusement halls, for example, when a fraudulent act is made by opening the front door or operating a winning device during business hours, etc. It may be adapted so that the pachinko balls stored in can not be launched from the launching device.

It is a perspective view which shows the external appearance of the slot machine of this invention. It is a perspective view which shows the state which opened the lower door of the slot machine. It is a perspective view showing the setting change device of the slot machine. FIG. 4 is a block diagram schematically showing an electrical configuration of the slot machine.
