Note that the setting change prohibition time zone switch 205b may be provided with a time setting function by using a dial switch or the like for inputting the time by a numerical value.

  A real-time clock 210 outputs time information or time information and date calendar information. The date, day of the week, and time when some operation is performed can be determined by the output of the real-time clock 210. Reference numeral 212 denotes a setting change time zone storage unit that stores in advance information related to time zones in which setting changes are prohibited. 213 is a setting for performing the determination when the setting of the time zone for prohibiting the setting change is ON, that is, when the permission or non-permission of the setting change is determined with reference to the table of the setting change time zone storage unit 212. It is a change time zone determination unit. The setting change time zone storage unit 212 may be realized by a memory (for example, an EEPROM) independent of the main board 200 or may be realized by a memory on the main board 200. The real-time clock 210 and the setting change time zone determination unit 213 may be realized by hardware independent of the main board 200, or may be realized by software by the CPU of the main board 200.

Next, an apparatus / method according to Embodiment 1 of the invention will be described.
As described above, the gaming machine basically pays out medals when the patterns are aligned, but whether or not the patterns are aligned depends on the result of a lottery by a computer inside the main board. Various prizes, such as big bonuses, regular bonuses, and small roles, also follow the results of internal computer lottery. The contents of the lottery process can be set within a predetermined range. The setting change is executed by a predetermined procedure such as opening the door of the gaming machine, turning on the setting key switch 2054 provided in the power supply unit 205, and pressing the setting change switch 2055.

  The main point of the first embodiment of the present invention is that a time zone in which setting change can be prohibited is set in advance, and the time zone is monitored to prevent a setting change due to fraudulent activity during business. That is, the setting change is usually performed before or after the hall business. Therefore, a time zone corresponding to business hours is set in advance as a setting change-impossible time zone, and when a setting change is performed during that time zone, it is determined that the act is an illegal act and an error state is explicitly expressed.

  A specific procedure executed by the CPU of the main board 200 will be described with reference to the flowchart of FIG.

S1: In FIG. 5, in order to monitor the setting change time, the power switch 2051 of the power supply unit 205 is turned on. As a result, energization of the main board 200 and the sub board 201 is started.

S2: It is determined whether or not to set a setting change time zone. This setting is performed as follows, for example. One or more of the following (1) to (4) can be selected.
(1) When the power is turned on, the setting change prohibition time zone switch 205b is enabled or the setting key switch 2054 is turned on. When the setting change prohibition time zone switch 205b is invalid or the setting key switch 2054 is off, the permission or non-permission determination based on the setting change time zone is not performed.
(2) The setting change / reset switch 2055 is turned on. When the setting change / reset switch 2055 is OFF, whether to permit or not permit based on the setting change time zone is not determined.
(3) Or the stop switch 2053 is turned ON. When the stop switch 2053 is OFF, whether to permit or not permit based on the setting change time zone is not determined. As will be described later, the stop switch 2053 may be used to switch between entering and not entering the setting change time zone setting mode.
(4) By pressing all or part of the switches of the operation unit 202, for example, the start bar, stop switch, and bet switch in a specific order within a certain period of time after turning on the power, permission or disapproval based on the setting change time zone Make a decision. For example, the setting may be performed by pressing the first, second, or third stop switch of the stop switch 140 in this order. Furthermore, it is also possible to determine permission or disapproval based on the setting change time zone by turning on the power while pressing a predetermined switch of the operation unit 202.

  As in (2) to (4), the above setting can be performed using an existing switch. Alternatively, it is of course possible to add a new setting switch as in (1).

  In the first embodiment of the present invention, for example, monitoring is performed so that the setting cannot be changed during business hours. However, when this monitoring is canceled as necessary, the setting change disabled time zone is not set. It is possible to make a setting not to execute the fraud prevention method according to the first embodiment. In addition, when canceling the setting for performing the fraud prevention method once performed, the setting may be performed after turning off the power, or by setting a predetermined switch operation.

  S3: A setting change time zone is set. For example, if the stop switch 2053 is turned on when the power is turned on, the setting change time zone setting mode is entered. That is, a setting change impossible time zone is set in the setting change time zone storage unit 212.

The procedure for setting the setting change permission time zone is, for example, as follows.
(11) If the stop switch 2053 is turned on when the power is turned on, the setting change permission time zone setting mode is entered. In the above examples (1), (2), and (4), if the stop switch 2053 is set to OFF when the power is turned on, the setting change permission time zone setting mode is not entered. In this case, the setting change time zone determination unit 213 determines based on the table already stored in the storage unit 212.
(12) When the setting change permission time zone setting mode is entered, the start lever 134 is pressed to change the start time of the time zone (similar to the setting of the digital clock). The set contents are displayed on the liquid crystal display device of the effect display unit 204. Alternatively, the lamp of the display unit 204 blinks a predetermined number of times according to what time. The start time may be changed by pressing the stop switch 140. At this time, the first, second, and third stop switches may be set switches for setting the date (day of the week), hour, and minute, respectively.
(13) The end time of the time zone is changed by pressing the start lever 134 again. The changing method is the same as in the case of (12).
(14) Press this start lever again to end this setting change procedure.

Needless to say, (11) to (14) are examples, and the present invention is not limited thereto.
In addition, although the permission or non-permission is determined based on the setting change time zone, the change of the setting change permission time zone may be skipped (determination is performed based on a table already stored in the storage unit 212). A process for determining whether or not to change the setting change permission time zone may be provided between S2 and S3 in FIG.

  FIG. 6 is a schematic diagram illustrating an example of the setting change time zone table that is already stored in the storage unit 212, that is, a setting change impossible time zone and a setting change available time zone. Normally, setting changes are made before the hall starts or after it closes. Therefore, as shown in FIG. 6, the opening time of the hall corresponding to the opening of the hall and before and after the opening time are set in the setting change impossible time zone A, and other times are set in the setting changeable time zone B. As shown in FIG. 4, a real-time clock (RTC) 210 that functions as a timer is connected to the main board. Once the time is set, the real-time clock 210 can keep ticking with power supplied from a backup power source (not shown) even when the power is turned off. There is no need to reset the time, which is suitable for real-time time management.

S4: It is determined whether a setting change request, specifically, an ON signal of the setting key switch 2054 in FIG. 3 has been received. Up to now, when the main board 200 receives the ON signal of the setting key switch 2054, it always shifts to the setting change state. For this reason, even if the setting is changed due to fraud during hall operation, the same operation as the normal setting change is performed. However, in the present invention, the time zone when the setting change request, in this example, the ON signal from the setting key switch 2054 is received, is monitored.

S5: It is determined whether the received setting change request is the setting change unavailable time zone A or the setting change available time zone B. Since the time when the setting change request is received can be specified by the real time clock 210, the setting change time zone determination unit 213 compares this time with the time preset in the setting change time zone storage unit 212.

S6: If the time is within the setting changeable time zone B, it is determined that the setting change process is normal, and the process at the time of setting change is performed.

S7: On the other hand, if the above time is within the range of the setting change impossibility time zone A, it is determined that the setting change processing is invalid and error processing is performed. For example, a command is sent to the sub-board 201, and the buzzer of the effect display unit 204 is sounded and the lamp blinks. This state continues until the reset switch 2055 is pressed. Processing may be performed so that the main board 200 does not accept a game together with the error notification by the sub board 201 or instead. In this way, the gaming machine is frozen and the game cannot be continued. In this way, it seems that fraudulent acts are strongly discouraged, which is effective in preventing fraud.

  In the embodiment of the invention described above, the case where the real-time clock 210, the setting change time zone storage unit 212, the setting change time zone determination unit 213, and the like are provided on the main board 200 has been described. You may make it provide.

  According to the gaming machine and the fraud prevention method according to the first embodiment of the present invention, by setting a time zone in which setting change is prohibited and monitoring the time at which the setting change is performed, a predetermined appropriate time zone. Change the settings only in. As a result, if the setting change operation is performed illegally during business hours when normal setting change is not performed, the setting change is not permitted and a buzzer or the like may be notified that the fraud has occurred. it can. As a result, fraud can be effectively prevented.

Embodiment 2 of the Invention
In the first embodiment of the invention, the setting change time zone setting is monitored in real time using the real-time clock 210. However, in the second embodiment of the invention, the real-time clock 210 includes the time function and the day of the week or the year / month / day. Have a calendar function. Then, the information regarding the day of the week or the year, month, and day is stored in the setting change time zone storage unit 212 as information regarding whether or not the setting change regarding the internal operation is possible. The setting change time zone determination unit 213 also compares and determines the day of the week and the date of the month together with the time. By configuring in this way, it is possible to link the information of the setting change unavailable time zone with the calendar information including information such as the day of the week, the date of the month, and the like, thereby enabling the long-term setting change time zone to be monitored. .

  FIG. 7 is a diagram illustrating a case where the setting change time zone is set in units of one week. In the figure, the setting change impossible time zone A and the setting changeable time zone B are managed in units of one week. For example, when Monday is a regular holiday, it can be set as the setting changeable time zone B in the same way as the hall closing time. . In this case, the entire Monday can be set as the setting changeable time zone B, or a part of the time can be set as the setting changeable time zone B. Further, the entire day of the week other than the regular holiday may be set as the setting change impossible time zone A. Further, FIG. 8 is a diagram illustrating a case where the setting change time zone is set in units of one month. In the figure, the setting change impossible time zone A and the setting changeable time zone B are managed in units of one month. For example, when Monday is a regular holiday, it can be set as the setting changeable time zone B in the same way as the hall closing time. . The entire day of the week other than a regular holiday may be set as the setting change impossible time zone A. Further, the 31st day in FIG. 8 is a temporary closing day, and can be set as a setting changeable time zone B (indicated by “OK *” in the figure). It is also possible to set the setting change time zone in units of one month in units of one year or more, year, month, and day.

  In the second embodiment of the present invention described above, the case where a holiday is set as the setting changeable time zone B has been described. However, according to the situation of the hall, the holiday is appropriately set as the setting change impossible time zone A. Of course it is possible.

  In the first and second embodiments of the present invention described above, it was impossible to change the setting in the setting change impossible time zone A, but a special setting change procedure different from the normal procedure (for example, an error always occurs when trying to change the setting). When you are notified and a reset operation is required, or when you follow a specific complicated process (such as pressing the left button, middle button, start lever, setting change switch, etc. in order) May be. For this, refer to the description of the third embodiment of the invention.

Embodiment 3 of the Invention
In the first and second embodiments of the present invention, a time zone or day of the week in which settings can be changed or a time zone or day of the week in which settings cannot be changed is provided. In this way, the time zone can be fixed or fixed. On the other hand, in the third embodiment of the present invention, a timer is set when the power is turned on or when the setting is changed, and a predetermined time from the start of the timer operation is set as a setting change impossible time zone. In this method, a fixed time interval is provided between setting changes, and the time zone can be set separately from the business hours, which can be made variable.

  FIG. 9 is a functional block diagram of the slot machine according to Embodiment 3 of the invention. This figure corresponds to FIG. 4, in which the same reference numerals indicate the same or corresponding parts. A description of the same reference numerals will be omitted.

  In FIG. 9, 214 is a timer for setting a fixed time interval between setting changes. Typically, a predetermined time is set in advance in the timer 214, and the output of the timer 214 becomes zero after the predetermined time has elapsed since the start. With this, it can be known that a certain time has passed since the previous setting change. The timer 214 can be said to correspond to the setting change time zone storage unit 212 of FIG. Therefore, the setting change time zone determination unit 213 determines whether it is a time zone in which setting change is prohibited based on the output of the timer 214 (specifically, whether the output is zero), and causes the setting change according to the result. .

  Reference numeral 215 denotes a special procedure storage unit for setting change. In the special procedure storage unit 215 for setting change, special procedures for specially changing the setting even during a setting change impossible time zone (left button, middle button, start lever, setting change switch,. Etc.) are stored. Since this special procedure can be input from the operation unit 202 of the gaming machine, a special procedure can be defined for each hall so that only those who are familiar with the situation (for example, the store manager) can change the setting.

  A specific procedure relating to the embodiment of the present invention will be described with reference to the flowchart of FIG. The power switch 2051 of the power supply unit 205 is turned on. As a result, energization of the main board 200 and the sub board 201 is started, and the setting change time monitoring process is started.

S10: It is determined whether or not a setting change request, specifically, an ON signal of the setting key switch 2054 in FIG. 3 has been received. For example, the time zone in which the ON signal is received from the setting key switch 2054 is monitored.

S11: It is determined whether the received setting change request is the setting change unavailable time zone A or the setting change available time zone B. An example of this is shown in FIG. FIG. 12A shows a case where the time zone is set with reference to the power-on time during the hall opening preparation. Since the timer 214 is set slightly longer than the hall opening time, the setting change time zone A is set during the hall opening. FIG. 12B shows the case where the time zone is set based on the normal setting change after the hall is closed in addition to FIG. In this case, even after the hall is closed, the setting change impossible time zone A is set. The setting change time zone determination unit 213 checks the output of the timer 214 when a setting change request is received. If this is zero, the setting change time zone determination unit 213 determines that the setting change time zone B is not. judge.

S12: If the time is within the setting changeable time zone B, it is determined that the setting change process is normal, and the process at the time of setting change is performed.

S13: The timer 214 is reset and the setting change impossibility time zone A is set.

S14: On the other hand, if the time is within the range of the setting change impossibility time zone A, it is determined that the setting change process is invalid and error processing is performed.

S15: If an operation is performed in this case, this is compared with the special procedure stored in the special procedure storage unit 215 for setting change. If the two match, the setting is specially changed. For example, pressing the left button, middle button, start lever, setting change switch, etc. in order.

  Next, the setting procedure of the timer 214 when the power is turned on will be described with reference to FIG.

S20: It is determined whether the memory (RAM) of the main board 200 has been backed up after the power is turned on. If not backed up (NO in S20), the timer 214 needs to be initialized, and the process proceeds to step S22.

S21: It is determined whether the output of the timer 214 is zero. If zero (YES in S21), the timer 214 needs to be initialized, and the process proceeds to step S22. If it is not zero (NO in S21), the timer 214 is not initialized so as to make use of the setting.

S22: The timer 214 is initialized. A count of a predetermined time is started by initialization.

  In the embodiment of the present invention described above, the case where the setting change time zone determination unit 213, the timer 214, and the setting change special procedure storage unit 215 are provided on the main board 200 has been described. You may do it.

  According to the third embodiment of the invention, since it is determined by the timer whether setting is possible or impossible, the time period is not fixed. Regardless of whether the hall is opened or closed, the interval between setting changes can be kept for a certain time or more, and frequent setting changes can be prevented.

  In addition, since a special procedure is set in advance and the setting can be changed even in a setting change impossible time zone by the special procedure, the setting change is enabled even in a setting change impossible time zone if it is unavoidable. Security can be improved by making the special procedure more complicated than the normal procedure.

  The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the invention described in the claims, and these are also included in the scope of the present invention. Needless to say.
