The hopper motor 50a is for rotating a disk disc (not shown) in which a plurality of circular hole portions for receiving medals one by one are arranged along the circumference. The disk has a function of pushing out and ejecting the medals accommodated in the circular hole toward the medal payout opening 44 as it rotates. When the credit function is activated, a part of the predetermined number of medals to be paid out as a bonus is stored in the storage tank 52 and credited. The payout button 37 is operated to pay out the credited medal to the receiving tray 45.

  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 changing the setting value, the game hall manager inserts the setting change key 55d into the setting change key cylinder 55a, and rotates from the OFF position to the ON position. When the power switch 55b is turned on, a setting change signal is input from the setting change board 55e to the control unit 60, and the mode is changed to the setting change mode. When the setting change mode is entered, the setting value can be changed by pressing the setting value change button 55c. When the setting value change button 55c is pressed, the control unit correspondingly corresponds to the control unit via the setting change board 55e. The set value signal is input to 60, 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 55f 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”.

  To confirm the setting value changed in the setting change mode, a confirmation operation is performed. In the slot machine 3 of the present invention, a single bet button 35, a MAX bet button 36, a start lever 38, stop buttons 40, 41, and 42 as game operation means, and a credited medal are paid out to the receiving tray 45. A confirming operation selection unit 56 is provided for selecting one of the payout buttons 37 as the payout operation means as the confirming operation means. Which operation means is the correct confirmation operation means is determined by the confirmation operation selection unit 56 by a method described later.

  On the other hand, the slot machine 3 of the present invention is provided with a determination unit 57, and the confirmation operation means selected by the confirmation operation selection unit 56 and the confirmation operation means actually operated for confirming the set value coincide. It is determined whether or not. If the two values match, the set value is confirmed. If the values do not match, a command is issued from the CPU 61, the notification control unit 91 is activated, and an error is notified by the notification device 91a. In addition, although the objective is achieved by providing a visual display device such as an LED as the alarm 91a, the liquid crystal display device 23 provided in advance for enhancing the fun of the game, a speaker (not shown), etc. May be combined.

  The confirmation operation selection unit 56 includes a lottery unit 56a. If, for example, the start lever 38, which is currently selected as the confirming operation means, is operated to confirm the set value, it is determined whether or not the actually operated start lever 38 and the selected confirming operation means match. The determination part 57 determines. In this case, since they match, the CPU 61 confirms the set value, and at the same time, the lottery unit 56a operates to select the next confirming operation means by lottery. The selected confirming operation means becomes effective after the game mode that is shifted to after the end of the current setting change mode. Thereafter, by returning the setting change key 55d inserted into the setting change key cylinder 55a from the ON position to the OFF position, the setting value displayed on the 7-segment display device 25 is newly set, and the setting change key 55d is changed from the setting change key cylinder 55a. When is removed, the setting change mode ends and the game mode is entered. In addition, it is preferable to notify the hall computer 7 of the confirmation operation means selected above so that the manager of the game hall can easily manage.

  When the game is started, one of the first to sixth winning tables 63a to 63f corresponding to the newly set value is read from the ROM 62, and the game is controlled with the winning probability corresponding to the set value. When the setting change key cylinder 55a is not operated to the ON position, no setting value is displayed on the 7-segment display device 25 even when the power switch 55b is ON, and the setting value change button 55c is pressed. However, the set value is not switched. Further, in this embodiment, there are six set values “1” to “6” that can be selected, and each set value is associated with the first to sixth winning tables 63a to 63f. The number of corresponding winning tables is not limited to this, and may be more or less.

  The operation of the slot machine 3 configured as described above will be described with reference to the flowchart of FIG. The game hall manager changes the winning probability setting by operating the setting changing device 55 outside the business hours of the game hall. In order to change the setting, after the lower door 17 is unlocked, the power switch 55b provided in the setting change device 55 is temporarily turned off. Then, the setting change key 55d is inserted into the setting change key cylinder 55a and turned from the OFF position to the ON position, and the power switch 55b is turned ON. At this time, the CPU 61 can accept the change of the set value by the set value change button 55c, and shifts to the setting change mode.

  The set value is changed while the set value is displayed on the 7-segment display device 25 by operating the set value change button 55c. When the set value is determined, the start lever 38 that is currently selected as the confirmation operation means is operated. Since the determination unit 57 determines that the selected operation means selected and the actually operated confirmation operation means match, the CPU 61 determines the changed set value. At the same time, the lottery unit 56a of the confirmation operation selection unit 56 is activated, and one of the one-bet button 35, the MAX bet button 36, the payout button 37, the start lever 38, and the stop buttons 40 to 42 is determined by lottery next time. Select as operating means. For example, the payout button 37 is selected as the next confirmation operation means. The selected confirming operation means becomes effective after the game mode that is shifted to after the end of the current setting change mode. Thereafter, the setting change key 55d inserted into the setting change key cylinder 55a is turned from the ON position to the OFF position, the setting change key 55d is removed from the setting change key cylinder 55a, the setting change mode is terminated, and the game mode is entered. Transition.

  When starting the game, the player inserts a medal from the medal insertion slot 43. The medal passes through the selector and is sent to the storage tank 52. The selector detects whether or not the medal is appropriate. When the medals are inappropriate, the medals are discharged from the medal payout opening 44 to the tray 45. If the medal is appropriate, the medal passes through the inserted medal sensor 75 provided at the rear end of the selector, receives the signal from the inserted medal sensor 75, and the CPU 61 counts the number of medals inserted.

  After inserting the required number of medals for one game, the bet number is set by operating the one bet button 35 or the MAX bet button 36, and the start lever 38 is operated to start the rotation of the reels 21a to 21c.

The player operates the stop buttons 40, 41, and 42 to stop the reels 21a, 21b, and 21c, and repeats the game while expecting that a predetermined pattern is stopped and displayed on the winning effective line.

  By the way, a player plays a game in order to acquire many medals, and for this purpose, there are players who illegally attempt to acquire many medals by changing setting values illegally. For example, a player who intends to cheat while a game is being played operates the power switch 55b by opening the lower door 17 or inserting a foreign object such as a wire through a gap in the machine body or the medal slot 43. Or operating the setting change key cylinder 55a, the setting value change button 55c, the setting change board 55e, or the like.

  The start lever 38 is operated to change the setting value and confirm the setting value. When the game hall administrator performs the setting change operation, the payout button 37 is selected as a new confirmation operation means. Therefore, the determination unit 57 determines that the selected confirmation operation means and the confirmation operation means actually operated do not match. Based on this determination, the CPU 61 sends a command to the notification control unit 91 to operate the notification device 91a to notify an error. At the same time, the error signal transmission unit 93 transmits an error signal to the hall computer 7.

  The notification device 91a is stopped when the selected confirmation operation means matches the confirmation operation means actually operated. Even if the player who is cheating does not know why the error is reported, he / she repeatedly operates the start lever 38 to determine the set value. However, the set value cannot be determined, and the alarm 91a Continue to report errors.

  The manager of the amusement hall can know that an illegal act has been made by an error signal transmitted to the hall computer 7 or by an error notification in the slot machine 3 in which the illegal act has been made. The administrator goes to the slot machine 3 where the illegal act has been performed, and operates the payout button 37 as the selected confirming operation means to confirm the set value. Since the determination unit 57 determines that the confirmed operation means selected and the actually operated confirmation operation means match, the error notification of the notification device 91a is stopped.

  By configuring the slot machine of the present invention as described above, the player does not know which of the plurality of types of game operation means and payout means is the correct confirmation operation means. I can't. In addition, a determination means for determining whether or not the selected confirming operation means and the actually operated confirming operation means match is provided, and if the two do not match, an error notification is given, so that the player is illegal It is difficult to continue playing games, and damage can be kept to a minimum.

  In addition, when the selected operation means that is not the confirmation operation means is operated as the confirmation operation means, an error signal is transmitted to the monitoring means for monitoring the gaming machine, and the administrator determines the gaming machine that is about to be cheated. It can be easily discovered and the effect of the present invention can be further enhanced.
