Description

  The present invention relates to a gaming machine such as a slot machine installed and used in a game hall such as a pachinko parlor.

  Slot machines that are installed and used in amusement halls such as pachinko parlors are called pachislot machines, and medals earned by playing games (games) are given a certain value to the medals that are the game media. Can be exchanged for various prizes. In such a slot machine, a plurality of winning tables having different lottery and lottery probabilities of a plurality of types of winning combinations are provided in advance, and one of these winning tables is used during the game. Each of these winning tables is assigned a setting value. By changing the setting value, the corresponding winning table is selected.

  This setting value can be changed, for example, by inserting the setting key into a key cylinder provided in the power supply device and rotating it in a predetermined direction, while referring to the setting value displayed on the display device provided on the front door. Operate the setting change button. When the setting change button is operated, the setting value displayed on the display device is changed, and when the setting value intended by the person to change the setting is displayed, the operation unit for confirming the start lever or the like is operated. To confirm the set value. Thereby, in the game after the setting change, a winning table corresponding to the determined set value is selected, and a game using the selected winning table is performed. Note that because the winning table and the lottery probability of multiple types of winning combinations differ for each winning table, changing the set value changes the payout probability (payout rate) of the game medium to be paid out when playing a game. .

Since the setting change in this slot machine can be performed only by a specific person who owns the setting key described above, such as a game hall manager, the game shop clerk or player cannot change the setting. Yes. However, there are players who open the front door and change settings illegally. As a method of preventing such unauthorized setting change, for example, a detection means for detecting opening / closing of the front door is provided, and when the front door is opened illegally, an alarm sound is reproduced or a warning is displayed on the host computer. (Patent Document 1).
JP 2004-135844 A

  However, recently, there is a problem that a key for locking the front door or a setting key owned only by a specific person is duplicated, and unauthorized setting change is performed using the duplicated key or setting key. For example, since the control device that controls the slot machine cannot determine the authenticity of the key or setting key for locking the front door, it is easy to change the settings if the player who goes to the game hall obtains these keys and setting keys. There is a problem that can be done.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a gaming machine that can prevent an unauthorized setting change using a duplicated key or setting key.

  In order to achieve the above object, the gaming machine of the present invention rotates a plurality of reels at the start of a game, and based on the result of a lottery performed at the start of the game when a reel stop signal is output. In the lottery, each of the plurality of reels is stopped, and one of a plurality of symbols arranged on each of the plurality of reels is displayed from the display window, and the game mode for performing the game is shifted to the setting change mode. In a gaming machine in which probability setting can be changed, in any one of the plurality of reels, an authentication symbol storage means for previously storing a symbol displayed from the display window when the reel is stopped as an authentication symbol And a symbol identifying means for identifying a symbol displayed from the display window when the reel is stopped based on the output of the reel stop signal. And a symbol determination means for determining whether or not the symbol obtained by the symbol identification means matches the authentication symbol stored in the authentication symbol storage means, and the determination result of the symbol determination means is And a mode transition permission means for permitting transition to the setting change mode when they match. Note that the reel stop signal is, for example, a stop signal that is output when a stop button that is operated when stopping the rotation of the reel is operated, for example, a predetermined time after the reel starts rotating. Even when the stop button is not operated, a stop signal that is output when the reel is automatically stopped is also included.

  In addition, it is preferable that a reel determination unit that determines a reel for identifying a symbol displayed from the display window from the plurality of reels is provided.

  It is preferable that an authentication symbol changing unit for changing the authentication symbol stored in the authentication symbol storage unit is provided.

  Further, the authentication symbol storage means is provided in a game control device that executes game control in a gaming machine, and the connection between the power supply device that supplies power to the game control device and the game control device is released. It is preferable that the authentication symbol stored in the authentication symbol storage means is deleted.

  And an initialization unit that initializes the authentication symbol stored in the authentication symbol storage unit, and a condition determination unit that determines whether or not a condition for operating the initialization unit is satisfied. Is preferred.

  According to the gaming machine of the present invention, the plurality of reels are rotated at the start of the game, and the plurality of reels are stopped based on the result of the lottery performed at the start of the game when the reel stop signal is output. The probability setting in the lottery can be changed by displaying from the display window one of a plurality of symbols arranged on each of the plurality of reels and shifting from the game mode in which the game is played to the setting change mode. In any one of the plurality of reels, an authentication symbol storage means for previously storing a symbol displayed from the display window when the reel is stopped as an authentication symbol, and the reel stop signal A symbol identifying means for identifying a symbol displayed from the display window when the reel is stopped based on the output of the symbol; When the determination result of the symbol determination means and the symbol determination means for determining whether or not the symbol obtained by the above and the symbol for authentication stored in the authentication symbol storage means match, Since there is a mode transition permission means that allows transition to the setting change mode, when changing the setting, authentication work is required to shift to the setting change mode, and the duplicated locking key and setting key are used. It is possible to prevent unauthorized setting changes.

  In addition, since a reel determining means for determining a symbol for identifying the symbol displayed from the display window is provided from among the plurality of reels, it is necessary for authentication according to the number of reels for identifying the symbol. The combination of symbols will change, and the level of security can be set for each game hall.

  Further, since the authentication design changing means for changing the authentication design stored in the authentication design storage means is provided, the authentication design stored in the authentication design storage means is periodically changed, or By making random changes, security against unauthorized setting changes can be maintained at a high level.

  The authentication symbol storage means is provided in a game control device that executes game control in the gaming machine, and the electrical connection between the power supply device that supplies power to the game control device and the game control device is released. As a result, the authentication symbol stored in the authentication symbol storage means is erased. For example, even if the authentication symbol stored in the authentication symbol storage means is forgotten, the connection between the game control device and the power supply device is established. It is possible to perform authentication setting or setting change work only by releasing it once.

  Further, there are provided initialization means for initializing the authentication symbol stored in the authentication symbol storage means, and condition determination means for determining whether or not a condition for operating the initialization means is satisfied. For example, even if the user forgets the authentication symbol stored in the authentication symbol storage unit, the authentication symbol stored in the authentication symbol storage unit is initialized if the condition for operating the initialization unit is satisfied. Therefore, even if the user forgets the authentication symbol, the authentication symbol can be easily set or changed.

  The slot machine 2 according to the present invention includes a game mode for playing a game and a setting change mode for changing settings such as the probability of a lottery in a game in the game mode.

  As shown in FIG. 1, the slot machine 2 includes a first reel 10 and a second reel, which will be described later, inside a housing 3 including a storage box 4 and a front door 5 provided on the front surface of the storage box 4. 11, the third reel 12, a power supply device 35 (see FIG. 2), a hopper device 36 (see FIG. 2), and the like.

  The front door 5 is composed of two doors, an upper door 6 and a lower door 7. A display window 8 is provided on the upper door 6. A first reel 10, a second reel 11, and a third reel 12 are disposed at the back of the display window. As is well known, a plurality of types of symbols, for example, are arranged on the outer peripheral surfaces of the first reel 10, the second reel 11, and the third reel 12. When the first reel 10, the second reel 11, and the third reel 12 are stopped, three symbols arranged on the first reel 10, the second reel 11, and the third reel 12 via the display window 8. Displayed. As a result, a total of nine symbols are displayed through the display window 8, and three straight winning lines that are a combination of the symbols of the first reel 10, the second reel 11, and the third reel 12 are horizontally arranged with two diagonal lines 2. A total of five books are set. Hereinafter, a winning line that is valid when a bet is placed on the medal is referred to as a winning effective line. The medal betting includes betting using a credited medal, in addition to placing a medal directly from the medal insertion slot 28 and making a bet.

  A display device 14 is provided below the display window 8. For example, the display device 14 displays the number of games in the BB (Big Bonus) mode and the RB (Regular Bonus) mode that make it easier to win a game than the game in the normal mode. Is displayed.

  Various operation buttons such as a single bet button 20, a MAX bet button 21, and a payout button 22 that are operated at the start of the game are provided on the upper portion of the lower door 7.

  The single bet button 20 is a button that is pressed when a game is played using one inserted medal. The inserted medals include medals that have been credited in addition to directly inserting medals from the medal insertion slot 28. The MAX bet button 21 is pressed when a game is played using three inserted medals, which is the maximum usable number.

  In the vicinity of these buttons, a start lever 23, a first stop button 25, a second stop button 26, and a third stop button 27 are provided. The start lever 23 is operated when a game is executed. In the setting change mode, the start lever 23 is operated to confirm the changed set value.

  The first stop button 25 is a button that is pressed when stopping the rotating first reel 10. Similarly, the second stop button 26 and the third stop button 27 are buttons that are pressed when the rotating second reel 11 and the third reel 12 are stopped.

  The lower door 7 is provided with a medal slot 28 for inserting medals when playing a game. A selector is incorporated in the back of the medal insertion slot 28, and inappropriate medals are discharged to the medal tray 30 through the medal payout opening 29. In addition, when the medal is inserted at an improper timing such as when the selector is inserted in the middle of a game or in a state where various operation buttons are pressed, the selector receives the inserted medal as the medal tray 30. To discharge. In addition, since the number of medals to be inserted prior to the start of the game is limited to 1 to 3, medals inserted after the fourth one are discharged to the medal tray 30 when the credit function is not used.

  On the other hand, when the credit function is on, medals inserted after the fourth sheet are detected by the medal sensor 82 (see FIG. 3) provided in the selector, and then, for example, the inside of the slot machine 2 is limited to 50 sheets. It is stored in. When this credit function is used, a medal insertion operation is performed by operating the one-bet button 20 or the MAX bet button 21 described above, and the bet number is sequentially subtracted from the credit number. Further, when a winning is obtained as a result of the game, a medal that becomes a payout is also credited, and a medal credited when the payout button 22 is operated is paid out to the medal tray 30.

  As shown in FIG. 2, in addition to the first reel 10, the second reel 11, and the third reel 12, there is a power source for supplying power to the slot machine 2 inside the storage box 4 constituting the housing 3. The device 35, the hopper device 36, and the like are assembled. In FIG. 2, a plurality of symbols arranged on the outer periphery of the first reel 10, the second reel 11, and the third reel 12 are omitted in order to prevent the drawing from being complicated.

  The power supply device 35 is provided to supply power to the slot machine 2. In addition to the power switch 40 for switching the main power on / off, an initial setting input unit 45 is provided on the front surface of the power supply device 35. The initial setting input unit 45 includes a key cylinder 46, a setting change button 47, and a slide switch 48. The key cylinder 46 includes a key switch (not shown), and the key switch can be turned on / off by rotating a setting key 50 inserted into the key cylinder 46. When the power switch 40 is turned on after the key switch is turned on while the power switch 40 is turned off, the setting change mode is entered. Note that the operation for shifting to the setting change mode is merely an example, and need not be limited to the present embodiment.

  The setting change button 47 is a button that is operated when the winning table is selected. There are a plurality of winning tables in the slot machine 2, and a set value is assigned to each. In the present embodiment, the setting values are “1” to “6”, and the setting value displayed on the display device 14 every time the setting change button 47 is operated when the setting is changed is “1 → 2 →.・ → 5 → 6 → 1 →... The slide switch 48 is provided for switching whether to end or continue the game when the BB mode ends. The order of changing the setting values displayed when the setting change button 47 is operated need not be limited to the above description.

  The hopper device 36 is provided in the lower part of the storage box 4. As described above, the hopper device 36 operates when a game is obtained in the slot machine 2 and a winning is obtained, and medals for the winning are continuously paid out to the medal tray 30. In addition, when paying out a credited medal, the operation is performed by operating the payout button 22, and the credited medal is continuously paid out to the medal tray 30. A storage tank 55 that stores medals for payout is provided on the upper portion of the hopper device 36. In the storage tank 55, medals inserted from the medal insertion slot 28 are stored. The overflow storage box 56 stores medals discharged from the storage tank 55 when the number of medals stored in the storage tank 55 of the hopper device 36 exceeds a predetermined amount.

  FIG. 3 is a functional block diagram showing an electrical configuration of the slot machine. In FIG. 3, the power supply device is omitted. The slot machine 2 includes a game control device 70 that performs basic control in the game of the slot machine 2 and an effect control device 71 that performs an effect in the game being progressed by the game control device 70. In this case, a signal is output only from the game control device 70 to the effect control device 71. In the following, an example in which the game control device 70 and the effect control device 71 are separately configured is shown, but the game control device 70 and the effect control device 71 may be configured as a single control device.

  The game control device 70 includes a CPU 75, a ROM 76, and a RAM 77. When power is supplied to the slot machine 2, the CPU 75 reads the activation program stored in the ROM 76 and executes the program. Further, when an ON signal is input from the medal sensor 82, the bet program stored in the ROM 76 is read to perform bet processing and credit processing. In response to the game start signal output from the start switch sensor 85, the CPU 75 reads out the game control program stored in the ROM 76 and starts game processing.

  Indexes 10a, 11a, and 12a are provided at the reference positions of the first reel 10, the second reel 11, and the third reel 12, respectively, and the photosensors 90, 91, and 92 are used for each rotation, respectively. The passage of the indexes 10a, 11a, 12a is photoelectrically detected. Detection signals from the photosensors 90, 91, and 92 are output to the CPU 75 as a reset signal for each reel. Note that drive shafts of stepping motors 95, 96, and 97 are press-fitted into the first reel 10, the second reel 11, and the third reel 12, respectively. The reel 10, the second reel 11, and the third reel 12 rotate. In FIG. 5, for convenience, the first reel 10 and the stepping motor 95, the second reel 11 and the stepping motor 96, and the third reel 13 and the stepping motor 97 are surrounded by solid lines. Reference numerals 98, 99, and 100 denote drivers for driving the stepping motors 95, 96, and 97, respectively.

  The CPU 75 is provided with a pulse counter (not shown) for each stepping motor, and counts the number of drive pulses supplied to each stepping motor. As a result, each time a reset signal is input from the photosensors 90, 91, 92, it is cleared and up-counted again. By monitoring the count value of the pulse counter for each reel, the CPU 75 can identify, for example, which symbol has moved on the center winning effective line, and how much the reel should be rotated. It is possible to predict whether the target symbol will move on the winning line.

  A stop switch sensor is provided inside the first stop button 25, the second stop button 26, and the third stop button 27. When an ON signal from each stop switch sensor is input to the CPU 75, the CPU 75 stores in the ROM 76. With reference to the stored symbol table 105, a drive pulse is supplied to the corresponding stepping motor so that the target symbol is stopped from the display window 8. The symbol table 105 includes a table in which symbols arranged on each reel, an arrangement number, and the number of drive pulses from the reference position are associated with each other.

  The CPU 75 includes a control unit 120, a random number extraction unit 121, a winning combination determination unit 122, a symbol determination unit 123, and the like. Based on the game control program stored in the ROM 76, the control unit 120 executes, for example, rotation / stop control of the first reel 10, the second reel 11, and the third reel 12, a payout control in the case of winning, etc. .

  When power supply to the slot machine 2 is started, the random number extraction unit 121 starts a random number update process, and acquires a random number at the time when the ON signal from the start switch sensor 85 is output. The winning combination determination unit 122 selects a winning table based on the set value stored in the RAM 77 from the first to sixth winning tables 130 to 135 stored in the ROM 76, and extracts a random number using the selected winning table. It is determined whether the random number acquired by the unit 121 is one of a plurality of types of winning combinations and losers set in advance.

  In the first to sixth winning tables 130 to 135, random numbers are distributed to each of a plurality of types of winning combinations and lost. Among these winning tables, the distribution of random numbers to the winning combination increases in the order of the first winning table 130 → the second winning table 131 →... → the fifth winning table 134 → the sixth winning table 133. Thereby, for example, the winning probability of the winning combination is the lowest in the first winning table 130 and the highest in the sixth winning table 135. When the setting value is “1” in the setting change, the first winning table 130 is selected, and when the setting value is “2”, the second winning table 131 is selected. Similarly, in the case of the setting value “6”, the sixth winning table 135 is selected.

  The symbol determination unit (symbol determination means) 123 operates every time all of the first reel 10, the second reel 11, and the third reel 12 are stopped. Since the stop control of the first reel 10, the second reel 11, and the third reel 12 is performed by the control unit 120, the first reel 10, the second reel 11, and the third reel 12 displayed from the display window 8 are controlled. A total of nine symbols per reel (hereinafter referred to as an outcome) are grasped by the control unit (symbol identifying means) 120. Thus, when the first reel 10, the second reel 11, and the third reel 12 are stopped, the control unit 120 outputs the output displayed from the display window 8 to the symbol determination unit 123. Note that the RAM 77 stores in advance an outcome used for authentication when the mode is changed to the setting change mode (hereinafter referred to as an authentication outcome). Then, it is determined whether or not the outcome displayed from the display window 8 matches. The determination result is stored in the RAM 77. For example, when the game mode is changed to the setting change mode, if the determinations match, the control unit (mode change permission unit) 120 permits the change to the setting change mode. The determination result stored in the RAM 77 is overwritten for each game.

  In addition to the game control program, the ROM 76 stores a mode change program, the above-described symbol table 105, the first to sixth winning tables 130 to 136, and the like, which are used by the control unit 120.

  A RAM (authentication symbol storage means) 77 stores data for the control during the game, and stores a set value at the time of setting change and an authentication outcome. As described above, this authentication outcome is used by the symbol determination unit 123 when shifting to the setting change mode. The authentication outcome is set from the outcomes that are not won among the outcomes displayed from the display window 8. Further, when the mode is changed to the setting change mode and the changed setting value is confirmed, the output displayed from the display window 8 when the mode is changed to the setting change mode is stored as the authentication output.

  The effect control device 71 includes a CPU 140, a ROM 141, a RAM (stop position storage means) 142, and the like. The CPU 140 receives the signal from the game control device 70, refers to the effect program stored in the ROM 141, operates the effect device 155 such as a speaker or LED provided in the slot machine 2, and effects control in the game I do. In addition, when the symbol determination unit 123 of the game control device 70 determines that the outcome displayed from the display window 8 does not match the authentication outcome stored in the RAM 77, the control unit 120 In response to the output warning signal, the control unit 144 reads the warning display program stored in the ROM 141 and operates the effect device 150, for example, to reproduce the warning sound and control the light emission of the lamp.

  Next, the effect | action of this embodiment is demonstrated based on the flowchart of FIG. When the setting is changed in the slot machine 2, a medal is inserted and a medal bet is performed in the same manner as in the game operation. Thereafter, when the start lever 23 is operated, the first reel 10, the second reel 11, and the third reel 12 rotate. When the administrator presses the first stop button 25, the second stop button 26, and the third stop button 27, the reels corresponding to the pressed stop buttons stop and all the reels stop. . The control unit 120 performs reel stop control. When all the reels are stopped, the control unit 120 outputs the output displayed from the display window 8 to the symbol determination unit 123. In response to this, the symbol determination unit 123 reads out the authentication output stored in the RAM 77 and determines whether or not the output displayed from the display window 8 matches the authentication output. The determination result is stored in the RAM 77.

  When the output displayed from the display window 8 when all the reels are stopped is the output intended by the administrator, the administrator opens the lower door 7 and turns off the power switch 40. Then, the setting key 50 is inserted into the key cylinder 46 and rotated until the key switch is turned on. In this state, the power switch 40 is turned on. If all the reels are stopped and the outcome displayed from the display window 8 is not the outcome intended by the administrator, the above operation is repeated until the outcome intended by the administrator is displayed. Thus, for example, in the case of a player who cannot press the stop reel by pressing the stop button so as to stop and display the intended symbol from the display window, the so-called authentication outcome is known. However, since the authentication output cannot be easily displayed on the display window, even if the copy key is temporarily held, unauthorized setting change using the copy key can be prevented.

  When the power switch 40 is turned on, a key switch on signal is output to the controller 75. In response to this, the control unit 75 refers to the determination result stored in the RAM 77. For example, when the determination result stored in the RAM 77 matches the analyzed output corresponding to the authentication output stored in the RAM 77, the control unit 75 reads out the mode change program stored in the ROM 76 and The mode in the machine 2 is shifted to the setting change mode.

  When shifting to the setting change mode, the control unit 120 causes the display device 14 to display the current setting value via the driver 155. In this state, when the administrator presses the setting change button 47, the display of the setting value on the display device 14 is changed. For example, when the display of the set value is “3”, the display on the display device 14 is “4 → 5 → 6 → 1 →...” Every time the setting change button 47 is pressed. It will be changed. Then, when the setting value intended by the administrator is displayed, the pressing operation of the setting change button 47 is stopped and the start lever 23 is operated. By operating the start lever 23, the set value displayed on the display device 14 is confirmed as a new set value. After confirming the setting value, the administrator rotates the setting key 50 so that the key switch is turned off, and pulls out the setting key 50 from the key cylinder 46. As a result, the setting change mode is shifted to the game mode, and a game using the winning table corresponding to the newly set value is performed.

  When the start lever 23 is operated, the control unit 120 stores the setting value displayed on the display device 14 in the RAM 77 and determines the output displayed from the display window 8 when it is confirmed. The result is stored in the RAM 77. When changing to the setting change mode and changing the setting, the upper door 6 is not opened, so that the first reel 10, the second reel 11, and the third reel 12 are not rotated accidentally, There is no need to change the display. If any of the first reel 10, the second reel 11, and the third reel 12 can be rotated due to the configuration of the slot machine 2, it is displayed from the display window 8 by the determination in the symbol determination unit 123. If the result is the same as the authentication pattern, it is possible to store the authentication output at that time.

  On the other hand, when the determination result stored in the RAM 77 does not match the analyzed output with the authentication output stored in the RAM 77, the control unit 75 outputs a warning signal to the effect control device 71. In the case of this determination result, the transition to the setting change mode is not performed. When the production control device 71 receives the warning signal, it reads out the warning program stored in the ROM 141, and reproduces the warning sound by the speaker as the production device 150 and displays the warning by controlling the lighting of the LED. Or you may make it output a warning signal to the hall computer which manages the slot machine 2 of a game hall. Accordingly, even if a player who attempts to change the setting illegally attempts to change to the setting change mode using the duplicated setting key 50, the setting value is changed illegally. Actions can be prevented.

  For example, if the administrator forgets the authentication output even though the setting of the slot machine 2 is being changed, all the data stored in the RAM 77 is initialized. As shown in FIG. 5, the game control device 70 is electrically connected to the power supply device 35 by a cable (connection means) 160. When initializing the data stored in the RAM 77, after the power switch 40 is turned off, the connector 161 provided at one end of the cable 160 is removed from the power supply device 35, and for example, for a predetermined time such as 30 minutes. Leave in condition.

  Although not shown, the game control device 70 keeps electricity supplied from the power supply device 35, and, for example, when a temporary power interruption occurs, the data stored in the RAM 77 is not initialized. For example, a storage battery such as a capacitor for supplying electricity is provided. For example, when the supply of electricity from the power supply device 35 is stopped by removing the connector 161 from the power supply device 35, the game control device 70 supplies electricity from the capacitor. When the electricity stored in this capacitor is exhausted, the RAM 77 is initialized. After leaving for a predetermined time, the connector 161 is attached to the power supply device 35, and the power switch 40 is turned on.

  In this case as well, as in the case where the initialization is not performed, the administrator performs the medal bet, the operation of the start lever 23, and the pressing operation of the stop button until the intended outcome is displayed from the display window 8, and then the power Switch 40 is turned off. Note that when the RAM 77 is initialized, the data for authentication stored in the RAM 77 is also initialized, so that the determination in the symbol determination unit 123 is not performed. When the set value is confirmed by operating the start lever 23 in the setting change mode, the output displayed from the display window 8 is stored in the RAM 77 as the output for authentication.

  Note that the method for initializing the RAM 77 is an example. For example, the power supply device 35 is provided with buttons and switches that are operated when initializing the data in the RAM 77, or the operation members provided in the slot machine 2 are operated. You may set suitably, such as setting it as operation different from operation in a game. When a button or switch is operated, or when an operation different from the operation in the game is performed, the control unit (condition determining means) 120 initializes the data for authentication stored in the RAM 77. It is determined that the condition is satisfied, and the control unit (initializing unit) initializes the authentication output data stored in the RAM 77. In this case, the data to be initialized may be all the data stored in the RAM 77 or only the data for authentication.

  In the present embodiment, a slot machine that does not include a liquid crystal display device has been described. However, a slot machine that includes a liquid crystal display device may be used. In this case, when the output displayed from the display window by the symbol determination unit does not match the authentication output stored in the RAM, a warning display is displayed on the liquid crystal display device when the mode is changed to the setting change mode. Can be done.

  In this embodiment, when all the reels of the first reel, the second reel, and the third reel are stopped, three reels displayed from the display window are displayed as a total of nine symbols. It is not necessary to limit to the form, and a symbol displayed from the display window when at least one of these reels is stopped may be used as the outcome. In this case, it is possible to provide reel determining means for determining a reel to be used for authentication inside the slot machine. In addition to this, a hall computer of the game hall is used as the reel determining means, and the reel used for authentication can be determined by this hall computer. Accordingly, for example, when one reel is used as an authentication reel, the security level is low, and when three reels are used as an authentication reel, the security level can be set high.

  In the present embodiment, the authentication output stored in the RAM is the output displayed from the display window when the set value is confirmed by operating the start lever. However, the present invention is not limited to this. It is also possible to arbitrarily set the output for authentication. In this case, it is necessary to provide an authentication change mode in the slot machine. The transition to the authentication change mode is executed, for example, by turning on the key switch while the power switch is on. Then, for example, by pressing the stop button (authentication pattern changing means) corresponding to the reel used for authentication, the authentication output is changed, and the start lever is operated to change the authentication output. It becomes possible. In this case, by providing a reel determination means for determining a reel to be used for authentication inside the slot machine, when changing to the authentication change mode, the reel to be used for authentication and the setting of the authentication output are set at a time. This can be done collectively, and authentication can be set easily.

  In the present embodiment, among the outcomes displayed from the display window 8, the outcome to be used as an authentication outcome is an outcome that does not become a prize. However, the present invention need not be limited to this, and the outcome that becomes a prize. Either may be sufficient. In this case, for example, it is conceivable to use a medal in which a storage medium such as an IC chip in which data for which the medal is not paid out is stored is embedded. In this case, a reading device for reading the contents of the IC chip embedded in the medal inserted into the slot machine is provided, and when the medal embedded with the IC chip is inserted, the medal is paid out. Programs that are not executed are stored in advance in the ROM of the slot machine. By adopting such a configuration, even when the authentication outcome is an outcome including winning, it is not necessary to pay out medals, and the troublesomeness at the time of changing the setting can be reduced.
