Abstract

<P>PROBLEM TO BE SOLVED: To enable the alteration of set values attributed to dishonest acts. <P>SOLUTION: With the shift to a setting alteration mode, a setting selection switch is depressed to allow the selection of a set value. After the end of the selection of the set value, a start lever is depressed and a start sensor is turned on, a defined time timer is actuated. When the depression of the start lever is released and the start sensor is turned off, the actuation of the defined time timer is stopped. This accomplishes the measurement of the time required for the depression of the start lever. Thereafter, in reference to a defined time table, it is determined whether the required depression time for the start lever is within the range of the reference time corresponding to the set value or not. When affirmative, the set value is defined. When the required depression time of the start lever exceeds the reference time, an error processing is conducted. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

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

  In this specification, a pachislot machine is described as an example of one of the gaming machines. Therefore, a description will be given using a medal as a gaming medium for playing a game, but the gaming medium may be other media such as a pachinko ball. Including. In addition, the lottery to determine one of the losers and multiple types of winning roles will be selected as the winning role lottery, and the symbols that make up the winning roles will be placed on the winning active line. The state until winning is the internal winning.

  Slot machines used in pachinko parlors are called pachislot machines. As is well known, in the pachislot machine, a plurality of types of payout rates with different winning probabilities are set. When the payout rate is changed, the probability that a profit is given to the player varies. Each payout rate is associated with a value called a set value on a one-to-one basis. When the set value is increased, the winning probability of the winning combination is increased accordingly. For example, the setting value is selected by turning on the power after turning the setting key to the ON position to shift to the setting change mode and pressing the setting change button in the setting change mode. When the start lever is pressed after selection of the set value is completed, the selected set value is confirmed, and it becomes possible to play a game under the selected set value. Thus, by setting the set value for each pachislot machine, there is an advantage that the operating profit can be predicted for the game hall and the game can be played fairly for the player. Furthermore, since there is a pleasure for a player to guess a pachislot machine with a set value having a high payout rate, the set value is important in terms of excitement of the game.

By the way, in recent years, a so-called goto act has been carried out in which the setting value is illegally changed by a method different from the regular method, and the pachinko parlor may lose profits. When a goth act is performed, the fairness of the game is lost, so there is a possibility that the game hall may suffer a loss of profit due to a decrease in players in addition to a direct loss of profit due to the goth act. For this reason, it is one of the important issues for each pachislot machine manufacturer to take countermeasures against the goto action. For example, in the pachislot machine of Patent Document 1, the set value is not changed within a predetermined time. It has been proposed to invalidate the selected setting value in the event of a failure.
JP 2006-254993 A

  However, Goto acts are becoming more and more malicious every year, and their methods are diversifying. As one of the methods of gotoing, for example, a method is known in which the door is unlocked using a foreign object such as a duplicated door key or wire, and the unlocked door is opened to change the set value. If this method is used, it is impossible for the pachislot machine to determine whether the set value has been changed normally or whether the set value has been changed by the goto action. I have to. However, it is difficult to find the goto action from the player's behavior, and confirming whether or not the goto action is being performed to the player who plays the game in a regular way The interest in gaming was lost, which was one of the reasons why the number of players playing games at pachinko parlors decreased.

  In order to solve the above-described problems, an object of the present invention is to provide a gaming machine that can prevent a set value from being changed due to a got action.

  In order to achieve the above object, the gaming machine of the present invention is used in a lottery for determining win or lose, and includes a plurality of winning lottery tables having different winning probabilities, and the selection operation of the winning lottery table is performed. In a gaming machine in which a game is performed using a selected winning lottery table when a predetermined confirmation operation is performed after the operation is performed, an operation required for at least one of the selection operation and the confirmation operation An operation time measuring means for measuring the required time and a confirmation operation enabling means for comparing the required operation time with a reference time set in advance and determining whether or not to validate the confirmation operation according to the comparison result It is equipped with.

  A plurality of the reference times having different lengths are set, and the confirmation operation enabling means is selected when the winning lottery table having a higher winning probability than the other winning lottery tables is selected. The reference time that is relatively longer than the other reference times is preferably used for the comparison.

  Further, it is preferable that the confirmation operation enabling means uses the reference time that is relatively longer than the reference time other than the reference time in the predetermined time zone for the comparison.

  Moreover, it is preferable to provide a notification signal output means for outputting a notification signal for notifying the reference time.

  According to the present invention, the setting value is changed because it is determined whether or not the confirmation operation is to be validated according to the operation time required for at least one of the setting value selection operation and the confirmation operation. It is possible to increase the labor at the time, and it is possible to prevent the setting value from being changed due to the goto action. In addition, since the goto action can be prevented by a software change, it is possible to reliably prevent the goto action while suppressing an increase in the manufacturing cost of the game machine without modifying the conventional game machine.

  Also, the higher the set value, the longer the time required for the operation, so it is difficult to raise the set value (to increase the winning probability per win) and make it difficult to gain profits from the goto action Can do.

  Also, in order to change the set value in a given time zone, the operation time must be longer than other times, so if you set the given time zone as the game hall business hours, Makes it difficult to goto, and employees can change the set values efficiently during non-business hours, making it difficult to perform goto acts while changing the set values properly Convenience can be improved.

  In addition, since the reference time to be compared with the operation time required to change the set value is notified, it becomes possible to use it as a guide when the game hall employee changes the set value. Convenience when changing the can be improved.

  As shown in FIG. 1, a slot machine (game machine) 11 installed in a pachinko parlor includes a slot machine main body 12 and a front door 13. The slot machine body 12 includes a storage box 12a. The storage box 12a stores a reel unit, a control board, a hopper device, and the like. The front door 13 is vertically divided into an upper door 13a and a lower door 13b. The inside of the slot machine body 12 is opened and closed by an upper door 13a and a lower door 13b.

  A display window 14 is provided on the upper door 13a. In the back of the display window 14, a first reel 15a, a second reel 15b, and a third reel 15c that are rotatable are provided. A plurality of types of symbols are arranged on the outer peripheral surfaces of the first to third reels 15a to 15c. When the first to third reels 15a to 15c are stopped, three symbols are displayed per reel through the display window 14. The In the slot machine 11, a total of five winning effective lines 16, consisting of three laterally and two diagonally, are set. Then, whether or not the winning combination has been won is displayed by the combination of symbols stopped on the winning winning line 16 when the first to third reels 15a to 15c are stopped.

  A liquid crystal display 17 is provided on the side of the display window 14. From the liquid crystal display 17, an effect image suggesting the result of the winning combination lottery, a mode image indicating that the mode is changing to the setting change mode, various error images, various setting images, and the like are displayed. Below the display window 14 is provided a 7-segment type display device 18 that displays the number of credited medals in the game mode and displays the set value in the setting change mode.

  The slot machine 11 includes six types of lottery tables used in the winning combination lottery. The lottery tables have different winning probabilities for winning combinations (winning). Then, depending on which lottery table is used to perform the winning combination lottery, the ratio of the number of medals paid out with respect to the number of medals inserted, that is, the payout rate, changes in a range of six stages. Each payout rate is associated with a value called a set value. The set value is composed of six stages of settings 1-6. The set values are associated with each payout rate so that the payout rate increases in the order of setting 1 → setting 2 → setting 3 → setting 4 → setting 5 → setting 6. In order to change the setting, it is necessary to shift from a game mode in which a game is performed to a setting change mode in which a setting value selection operation is performed.

  The lower door 13b has a medal slot 19 for inserting medals, a start lever 20 for starting rotation of the first to third reels 15a to 15c, and first to third stops for stopping the reels rotating during the game. Buttons 21a to 21c, a bet button 22 for betting a credited medal, and the like are provided.

  In the slot machine 11, a game start condition is to insert three medals. The third medal inserted from the medal insertion slot 19 is betted simultaneously with the insertion, and the fourth and subsequent medals are credited. When there are four or more medal credits, it is possible to bet three medals at a time by pressing the bet button 22. When the start lever 20 is pressed after betting a medal, a winning combination lottery is performed and the first to third reels 15a to 15c rotate all at once. In the winning combination lottery, one of a plurality of types of winning combinations or a loss is determined. The plurality of types of winning combinations are composed of a BB that shifts to the BB mode, which is more advantageous to the player than the normal mode, a small role in which medals are paid out, and a replay that allows the next game to be performed without inserting medals.

  When the first to third reels 15a to 15c start rotating and the first to third stop buttons 21a to 21c are operated and then pressed, the corresponding first to third reels 15a to 15c are pressed. Stops individually. A cancel button 23 is provided on the side of the first to third stop buttons 21a to 21c. When the cancel button 23 is pressed before the start lever 20 is pressed, the inserted medal is returned to the medal tray 25 through the payout port 24. The medal is paid out to the medal tray 25 through the payout port 24 even when the small role or BB wins.

  As shown in FIG. 2, a power supply box 30 is provided in the storage box 12 a of the slot machine body 12. The power supply box 30 is exposed to the outside when the lower door 13b is opened. The power supply box 30 is used not only to turn on the slot machine 11 but also to select a setting value in the setting change mode.

  As shown in FIG. 3, the power supply box 30 is formed in a box shape. On the front surface of the power supply box 30, there are provided a setting key switch 31 for switching whether or not to shift to the setting change mode, a power switch 33 for switching on / off the power, and a setting selection switch 34 for selecting a setting value. Yes.

  The setting key switch 31 is composed of a key cylinder. When shifting to the setting change mode, the setting selection key 32 is inserted into the setting key switch 31. After the setting selection key 32 is inserted, when the setting selection key 32 is turned from the off position to the on position and the power switch 33 is turned on, the game mode is changed to the setting change mode. When the mode is changed to the setting change mode, the operation (selection operation) of the setting selection switch 34 is validated, and medals inserted from the medal insertion slot 19 are not accepted and it becomes impossible to play a game.

  When the setting selection switch 34 is pressed in the setting change mode and the setting selection switch 34 is turned on, the setting value in six steps is set for each push. Setting 1 → setting 2 → setting 3 → setting 4 → setting 5 → setting 6 → Select one by one in a sequence of settings 1 ... Then, after the setting value is selected with the setting selection switch 34, when the start lever 20 is pressed (confirmation operation), the setting value is confirmed. When the setting selection key 32 is turned to the off position after the set value is confirmed, the setting change mode is shifted to the game mode, and the game is played under the confirmed set value.

  As shown in FIG. 4, the operation of the slot machine 11 is basically controlled by the control board 60. The control board 60 includes a CPU 60a and a working memory 61. The CPU 60a includes a control unit (confirming operation validating means, notification signal output means) 62 for controlling the operation of the CPU 60a, a winning combination determining unit 63 for executing a winning combination lottery, and a time required for a setting value determining operation and a comparison with this. A fixed time table 64 in which the reference time is associated with each other, and a fixed time timer (operation time measuring means) 65 for measuring the time required for the setting value determining operation.

  The ROM area of the working memory 61 stores a game execution program and game execution data used in the game execution process, and a setting change program and setting change data used in the process in the setting change mode. The control unit 62 reads out a game execution program and game execution data from the working memory 61 to perform processing related to the operation of the slot machine 11. The RAM area of the working memory 61 is used for temporary storage and rewriting of flags and data used for each game.

  The medal sensor 66 detects a medal inserted from the medal slot 19. When a medal is detected by the medal sensor 66, the detection signal is input to the control unit 62. In response to the medal detection signal from the medal sensor 66, the control unit 62 activates the winning payline 16.

  The start sensor 67 detects that the start lever 20 has been pressed. The start sensor 67 includes a photoelectric sensor that includes a light emitting element and a light receiving element. When the start lever 20 is pressed, the start sensor 67 is turned off by blocking light from the light emitting element. When the start lever 20 is released and returned to the initial position, the light receiving element receives the light from the light emitting element. Turn on. When the start sensor 67 is turned on from off, a start signal is output to the control unit 62. Therefore, on / off of the start sensor is identified by the presence / absence of the start signal. If three or more medals are not bet, the control unit 62 cancels even if a start signal is input. Thereby, the activation / invalidation of the operation of the start lever 20 is switched. When the start signal is input, the control unit 62 operates the winning combination determination unit 63 to perform the winning combination lottery, and then rotates the first to third reels 15a to 15c to rotate the first to third stops. The operation of the buttons 21a to 21c is validated. In the setting change mode, the control unit 62 determines whether or not to confirm the set value in response to the start signal.

  The pressing of the first to third stop buttons 21a to 21c is detected by the first to third stop sensors 68 corresponding to the respective buttons. When pressing of the stop button is detected by the first to third stop sensors 68, a stop signal is input to the control unit 62.

  When the stop signal is input, the control unit 62 operates the reel drive controller 69 and starts stop control of the first to third reels 15a to 15c corresponding to the stop sensor to which the stop signal is input.

  The first to third reels 15a to 15c are attached to the drive shafts of the stepping motors 70a to 70c, respectively. The control unit 62 performs stop control of the first to third reels 15a to 15c by controlling driving of the stepping motors 70a to 70c.

  The stepping motors 70a to 70c rotate at a rotation angle corresponding to the number of drive pulses supplied from the control unit 62. Therefore, the control unit 62 controls the rotation angle of the first to third reels 15a to 15c by controlling the number of drive pulses supplied to the stepping motors 70a to 70c, and stops the supply of the drive pulses. Stop. The first to third reels 15a to 15c are integrally formed with reflection signal portions 71a to 71c at their reference positions. Then, every time the first to third reels 15a to 15c make one rotation, the photosensors 72a to 72c detect passage of the respective reflection signal portions 71a to 71c. Detection signals from the photosensors 72a to 72c are input to the control unit 62 as a reset signal indicating the reference position of the reel.

  The control unit 62 is provided with a pulse counter that counts the number of drive pulses supplied to each of the stepping motors 70a to 70c. When the reset signal is input from the photosensors 72a to 72c, the control unit 62 clears the count value of the corresponding pulse counter. Therefore, the number of drive pulses corresponding to the rotation angle within one rotation of each reel is stored in each pulse counter while being sequentially updated.

  The outer peripheral surfaces of the first to third reels 15a to 15c are divided into a plurality of frames for each predetermined range (21 frames will be described as an example in this embodiment), and one symbol is assigned to each frame. Yes. Each frame is assigned a frame number of “1” to “21”. In the ROM area of the working memory 61, each frame number and the number of drive pulses corresponding to the rotation angle from the reference position of each reel are displayed. Are stored in association with the symbol table. The control unit 62 can identify the frame number on the winning effective line 16 by monitoring the value of the pulse counter for each reel while referring to the symbol table. The type can be identified.

  When the rotation of the first to third reels 15a to 15c is started and the rotation speed of the first to third reels 15a to 15c reaches the steady speed, the control unit 62 sets the first to third stop buttons 21a to 21c. Enable the operation. When the first to third stop buttons 21a to 21c are pressed, the control unit 62 and the reel drive controller 69 perform known pull-in control. As a result, when the symbols corresponding to the winning combination won in the winning combination lottery are within the pull-in range, the winning symbols stop on the winning winning line 16 when the first to third stop buttons 21a to 21c are pressed. .

  The control unit 62 operates the winning combination determining unit 64 in response to the start lever 20 being pressed. The winning combination determining unit 64 includes a random number generator and a random number sampling circuit, and extracts a random number every time the start lever 20 is pressed.

  The winning combination determining unit 64 is provided with first to sixth setting tables 73a to 73f. In the first to sixth setting tables 73a to 73f, all random number values generated by the random number generator of the winning combination determining unit 64 are grouped into a plurality of numerical ranges, and each group includes one of a plurality of types of winning combinations or Loss is assigned. Then, the type of lost or winning combination is determined depending on which group the extracted random number value belongs to.

  Each of the first to sixth setting tables 73a to 73f is associated with six levels of setting values. In the first to sixth setting tables 73a to 73f, the numerical ranges of the grouped random numbers are different from each other, and thus the winning probabilities of the winning combinations are different from each other. For this reason, the payout rate of the slot machine 11 changes depending on which of the first to sixth setting tables 73a to 73f is compared with the random number value sampled by the winning combination determining unit 64.

  Of the first to sixth setting tables 73a to 73f, the first setting table 73a has the lowest payout rate, and the winning is such that the payout rate increases in the order of the second, third, fourth, fifth and sixth setting tables. The winning probability of the role is set. The first setting table 73a is selected when setting 1 is selected, the second setting table 73b is selected when setting 2 is selected, the third setting table 73c is selected when setting 3 is selected, and the fourth setting table 73c is selected when setting 4 is selected. The fifth setting table 73e is used when the setting table 73d and setting 5 are selected, and the sixth setting table 73f is used when setting 6 is selected.

  An ON or OFF signal is input to the control unit 62 from the setting key switch 31, the power switch 33, and the setting selection switch 34. The ON signal from the setting selection switch 34 is input when the setting selection switch 34 is pressed. The control unit 62 shifts from the game mode to the setting change mode when there is input of both the ON signal of the power switch 33 and the ON signal of the setting key switch 31, and no ON signal is input to the setting key switch 31. Then, the setting change mode is terminated and the game mode is entered.

  The control unit 62 causes the display device 18 to display the setting value being selected when the setting change mode is entered. For example, the setting value is “−1−” when setting 1 is set, “−2” when setting 2 is set, and “−3−3” when setting 3 is set. “−4” when setting 4 is set, “−5−” when setting 5 is set, “−6−” when setting 6 is set, and so on. (Set value)-"is displayed. Then, every time an ON signal of the setting selection switch 34 is input, the control unit 62 displays these indications as “−1−” → “−2” → “−3−3” → “−4−” → “ The display is switched in the order of “−5” → “−6” → “−1−” →. When the selected setting value is confirmed by pressing the start lever 20, the control unit 62 displays the confirmed setting value from the display device 18 in the form of "(setting value)" (-is not displayed). .

  In addition, the control unit 62 identifies the first to sixth setting tables 73a to 73f corresponding to the setting value selected by the setting selection switch 34. When the start lever 20 is pressed, the types of the selected first to sixth setting tables 73a to 73f are written in the RAM area of the working memory 61, and the set values are determined. Thereby, the selection of the set value is completed. When a game is played, the control unit 62 refers to the RAM area of the memory 61 and identifies the type of setting table for collating the random value sampled by the winning combination determining unit 64. Then, the winning combination lottery is performed using the identified first to sixth setting tables 73a to 73f.

  When the start lever 20 is pressed in the setting change mode, the time required for pressing is measured by the fixed time timer 65. The fixed time timer 65 operates when the start sensor 67 is turned on and stops when the start sensor 67 is turned off. Thereby, the time required for pressing the start lever 20 (time required for operation) is measured. When the time required for pressing is measured, whether or not to confirm the set value selected by the setting selection switch 34 is determined with reference to the confirmed time table 64.

  As shown in FIG. 5, in the fixed time table 64, the required time T for pressing the start lever 20, a plurality of reference times to be compared with the required press time T, and setting values are associated with each other. The reference time is different between the business hours AM10: 0 to PM11: 00 of the pachinko shop where the slot machine 11 is installed and the PM11: 0 to AM9: 59 hours outside the business time of the pachinko shop, PM11: 01 to AM9: 59 are relatively longer than AM10: 0 to PM11: 00. In any time zone, the reference time becomes longer as the set value becomes higher. The CPU 60 a includes a clock 74, and the business hours of the pachinko parlor are identified by the control unit 62 monitoring the clock 74.

  In the business hours AM10: 0 to PM11: 00, when the setting 1 is selected, the set value is confirmed when the time T required to press the start lever 20 is less than 1 second, which is the reference time. When setting 2 is selected, the set value is fixed when the time T required to press the start lever 20 is not less than 1 second and less than 3 seconds, which is the reference time, and when setting 3 is selected, the start lever 20 When the required pressing time T is 3 seconds or more and less than 5 seconds, which is the reference time, the set value is confirmed. When setting 4 is selected, the pressing required time T of the start lever 20 is 5 seconds or more, which is the reference time. When the setting value is confirmed when the setting time is less than 7 seconds and setting 5 is selected, the setting value is confirmed when the time T required to press the start lever 20 is 8 seconds or more and less than 10 seconds, which is the reference time. If is selected, Pressing duration T Trevor 20 set values of less than 12 seconds 13 seconds which is the reference time is determined.

  Further, in the time zone PM11: 01 to AM9: 59 other than business hours, when setting 1 is selected, the set value is determined when the time T required to press the start lever 20 is less than 5 seconds which is the reference time. When setting 2 is selected, the set value is determined when the required time T of pressing the start lever 20 is 5 seconds or more and less than 7 seconds, which is the reference time. When setting 3 is selected, the start lever When the required pressing time T of 20 is 7 seconds or more and less than 9 seconds, which is the reference time, the set value is confirmed, and when setting 4 is selected, the required pressing time T of the start lever 20 is 9 seconds, which is the reference time. When the setting value is confirmed when the setting time is less than 11 seconds and setting 5 is selected, the setting value is confirmed and set when the time T required to press the start lever 20 is 12 seconds or more and less than 14 seconds, which is the reference time. If 6 is selected, Set value is determined when pressing time required Tatoreba 20 T is less than 17 seconds 16 seconds or more, which is the reference time.

  The slot machine 11 is connected to a hall computer 75 installed in a pachinko parlor. The hall computer 75 includes a monitor 75a. In the setting change mode, the content of the fixed time table 64 is transmitted as a display signal (notification signal) from the control unit 62 to the hall computer 75. For this reason, employees of the pachinko parlor can check the reference time on the monitor 75a of the hall computer 75.

  Next, the flow of processing executed in the setting change mode configured as described above will be described.

  As shown in FIG. 6, when the operator who selects the setting value opens the lower door 13b and turns on the power switch 33, the slot machine 11 is turned on. If an ON signal is input to the setting key switch 31 when the power switch 33 is turned on, the control unit 62 shifts to the setting change mode.

  When the setting change mode is entered, the content of the fixed time table 64 is transmitted as a display signal to the hall computer 75, and the content is displayed from the monitor 75a of the hall computer 75. When the mode is changed to the setting change mode, the setting selection switch 34 is pressed to select a setting value. When the start lever 20 is pressed and the start sensor 67 is turned on after selection of the set value is finished, the fixed time timer 65 is operated. When the start lever 20 is released and the start sensor 67 is turned off, the fixed time timer 65 is turned on. Stops working. Thereby, the time required for pressing the start lever 20 is measured. Thereafter, the fixed time table 64 is referred to, and it is determined whether or not the time required for pressing the start lever 20 is within the range of the reference time corresponding to the set value. If the time required for pressing the start lever 20 is within the reference time range, the set value is confirmed. If the time required for pressing the start lever 20 exceeds the reference time, an error is detected from the liquid crystal display 17 as error processing. A screen is displayed. The error screen is canceled when the game mode is once shifted to the setting change mode again.

  In the above embodiment, it is determined whether or not to confirm the set value by comparing the operation required time of the setting value confirming operation with the reference time. However, the operation required time of the setting value selecting operation is compared with the reference time. It may be determined whether or not to confirm the set value. This example will be described below, but the same reference numerals are used for the same parts and members as in the above embodiment, and detailed description thereof is omitted.

  As shown in FIG. 7, in this embodiment, a setting selection time table 80 and a setting selection time timer (operation time measuring means) 81 are provided in place of the confirmation time table 64 and the confirmation time timer 65.

  The setting selection time timer 81 operates when the setting selection switch 34 is turned on in the setting change mode, and stops when the setting selection switch 34 is turned off. Thereby, the time required for pressing the setting selection switch 34 is measured.

  In the setting selection time table 80, the required pressing time T of the setting selection switch 34, the reference time compared with this, and the setting value are associated with each other. The associated reference times are the time zone AM10: 0 to PM11: 00 of the pachinko store where the slot machine 11 is installed and the time zone PM11: 01 to AM9: 59 outside the business time of the pachinko store. The reference time is relatively longer in PM11: 01 to AM9: 59 than in AM10: 0 to PM11: 00. In any time zone, the reference time becomes longer as the set value becomes higher. Note that the reference time in the setting selection time table 80 is the same as that in the fixed time table 64, and thus detailed description thereof is omitted.

  Next, the flow of processing executed in the setting change mode configured as described above will be described, but description of the same processing as in FIG. 6 will be omitted.

  As shown in FIG. 8, the setting selection time timer 81 is activated when the setting selection switch 34 is turned on in the setting change mode, and the operation of the setting selection time timer 81 is stopped when the pressing of the setting selection switch 34 is turned off. Thereby, the time required for pressing the setting selection switch 34 is measured. Since the setting selection switch 34 may be pressed a plurality of times, each time the setting selection button 34 is pressed, the time required for the pressing is individually written in the RAM area of the working memory 61. When the start lever 20 is pressed, the setting selection time table 80 is referred to and it is determined whether or not the time required for pressing the setting selection switch 34 is within the reference time range. If the time required for pressing the setting selection switch 34 is within the range of the reference time, the set value is confirmed. If the time required for pressing the setting selection switch 34 exceeds the reference time, the liquid crystal display 17 is processed as error processing. Will display an error screen. The error screen is canceled when the game mode is once shifted to the setting change mode again.

  In the above embodiment, the reference time is displayed from the monitor 75a of the hall computer 75, but it may be displayed from another slot machine or may be displayed by its own slot machine. When displaying on its own slot machine, encryption is preferable. Further, the reference time may be notified in an appropriate manner such as not only display on the monitor but also notification by voice. Furthermore, the time measured by the fixed time timer 65 or the setting selection time timer 81 may be counted up.

  In the above embodiment, the error screen is displayed from the liquid crystal display 17 as the error process. However, for example, an appropriate process such as disabling the game or performing voice notification may be performed.

  In the above embodiment, the setting value selection operation is performed by the setting selection switch 34 and the setting value confirmation operation is performed by the start lever 20, but these operations are performed by, for example, the bet button 22 and the first to third stop buttons 21a to 21c. The operation may be performed in an appropriate manner such as with the cancel button 23.

  In the above embodiment, a reel drive type slot machine has been described as an example. However, other gaming machines such as a slot machine that displays a symbol on a liquid crystal display, a slot machine that uses a game ball, and a pachinko machine, for example. The present invention may also be applied.
