Description

  The present invention relates to a gaming machine such as a slot machine, and more particularly to an improved security related to a change in settings related to a lottery process.

  In a gaming machine such as a slot machine, a player can enjoy a game by inserting a predetermined number of medals and game media such as a game ball into the gaming machine. The game media necessary for the game can be borrowed at a game media rental machine or the like provided in the game hall, and the game can be started by inserting it into the game media slot of the desired game machine.

  The slot machine basically pays out medals as prizes when the symbols are arranged, but whether or not the symbols are arranged depends on the result of a lottery by an internal computer. Also, various prizes such as a big bonus (BB), regular bonus (RB), and small role follow the result of the lottery by the internal computer. The content of the lottery process (internal operation) can be changed within a predetermined range, and the setting operation is performed by the store in a hall where a gaming machine is installed.

  A normal slot machine is previously provided with a plurality of lottery tables having different lottery probabilities such as BB, RB, and small roles. In the slot machine lottery, one of the plurality of lottery tables is set, and the winning / losing determination by lottery is made based on the set lottery table. Changing a setting relating to which of a plurality of lottery tables is used is referred to as a setting change (hereinafter referred to as “setting change”).

  Conventionally, for example, in a gaming machine such as a slot machine, when changing a setting value (usually 1 to 6), the door of the gaming machine is opened and a setting key is inserted into a setting key switch provided in a power supply unit. With the switch turned on, the game machine is turned on so that the setting can be changed. Each time the setting change button (push button) is pressed once, the setting value displayed on the 7-segment display or the like is incremented. Then, the values from 1 to 6 are cyclically changed, and the desired setting value is determined by operating the start switch when the desired setting value is displayed on the display.

Is not limited to this. A dedicated power source (for example, a battery) may be provided and supplied from now on. When the main power source is used, the current is supplied to the setting key switch 2054 only when the main power source of the gaming machine is on and the on / off device 2060 is on. Since the key switch 2054 is off, current may not be supplied. In the case of a dedicated power supply, the supply of current to the setting key switch 2054 can be turned on and off regardless of whether the main power supply of the gaming machine is turned on or off. The embodiment of the present invention can be applied to any configuration.
For example, the setting key switch power supply control unit 200a turns on the on / off device 2060 when the door opening detection sensor DS detects the opening of the front door 130 of the gaming machine. The ON timing will be described in detail later.

  The main board 200 is set based on a signal from the switch 2054 when the supply of current is turned on by the on / off device 2060 (the setting key switch 2054 is activated) and the setting key switch 2054 is turned on. Make a change.

  Reference numeral 200b denotes a power-on timer that starts timing from power-on. The setting key switch power supply control unit 200a turns on the on / off device 2060 after a predetermined time has elapsed since power-on based on the output of the power-on timer 200b.

  A gaming machine basically pays out medals when symbols are arranged, but whether or not symbols are arranged depends on the result of a lottery by an internal computer. Also, various prizes such as a big bonus (BB), regular bonus (RB), and small role follow the result of the lottery by the internal computer. The lottery process can be set within a predetermined range (the probability of winning can be increased or decreased), and the setting operation is performed by the store in a hall where a gaming machine is installed. A normal gaming machine includes a plurality of (for example, six) lottery tables having different lottery probabilities such as BB, RB, and small roles in advance. In the lottery of gaming machines, one of the plurality of lottery tables is set, and the winning / losing determination by lottery is made based on the set lottery table. Changing the setting relating to which of a plurality of lottery tables is used is referred to as setting change.

  FIGS. 5A and 5B are conceptual diagrams of internal connections of the power supply unit 205 according to the embodiment of the invention.

  In FIG. 5A, an ON / OFF device 2060 such as a relay is connected in series between the setting key switch power source 2061 and the setting key switch 2054. When the setting key switch 2054 is turned on (ON), a current from the setting key switch power source 2061 needs to be supplied to the setting key switch 2054 so that a signal to that effect is input to the main board 200. For example, when the main board 200 executes a setting change process when a high level (H level) signal having a voltage of about 5 V is input to the main board 200 as the setting key switch signal, the on / off device 2060 If the setting key switch 2054 is turned off and no current is supplied, the setting key switch signal does not become H level even if the setting key switch 2054 is turned on. Therefore, in order to enable the setting key switch 2054 to be turned on, the on / off device 2060 needs to be turned on.

  FIG. 5B shows a case where the main board 200 executes a setting change process when a low level (L level) signal whose voltage is about the ground voltage (0 V) is input to the main board 200 as the setting key switch signal. An example of a circuit that can be applied in this case is shown. In FIG. 5B, an ON / OFF device 2060 is connected in series between the setting key switch 2054 and the ground (GND), and the electric wire for the setting key switch signal (the common terminal of the setting key switch 2054) is a resistor. It is connected to the setting key switch power source 2061 via R (note that the resistor R is not necessary when the input terminal of the main board 200 is pulled up to H level). If the on / off device 2060 is off and the setting key switch 2054 is not grounded, the setting key switch signal does not become L level even if the setting key switch 2054 is turned on. Therefore, in order to enable the setting key switch 2054 to be turned on, the on / off device 2060 needs to be turned on.

  5A and 5B, the operation of the gaming machine according to the embodiment of the invention is the same.

FIG. 6 shows a setting change flowchart.
FIG. 6 shows the entire setting change procedure. First, the power of the gaming machine is turned off (S10), and the setting key switch 2054 is turned on (S11). Then, the gaming machine is turned on (S12). In the past, the setting change mode was entered immediately, but in the embodiment of the invention, the setting change mode is entered only when the on / off device 2060 is on. When the on / off device 2060 is off, the setting change mode is not entered, and the normal game mode is entered. When the setting change mode is entered, the setting is changed in the same procedure as before (S13). Specifically, the setting change / reset switch 2055 is pressed to set the setting value to a desired value. When the desired set value is reached, the start switch 134 is pressed to confirm the set value (S14). When the setting key switch 2054 is turned off (S15), the normal game mode is entered.

  FIG. 7 shows a setting key switch power on / off process flowchart according to the embodiment of the present invention.

  The setting key switch power supply control unit 200a determines whether it is time to turn on the setting key switch power supply (turn on / off device 2060 on) (S20). If the setting key switch power is turned on (YES in S21), the setting key switch is turned on by turning on the on / off device 2060 (S22). Otherwise (NO in S21), the on / off device 2060 remains off (S23).

  Next, a description will be given of the timing (predetermined timing) at which the on / off device 2060 should be turned on.

(1) After a certain time has elapsed since the power was turned on After a certain time has elapsed since the power was turned on, the on / off device 2060 is turned on. The setting key switch power supply control unit 200a makes a determination based on the output of the power-on timer 200b.

(2) When the front door is opened When the front door 130 is opened, the on / off device 2060 is turned on. The setting key switch power supply control unit 200a makes a determination based on the output of the door opening detection sensor DS.

(3) During reel rotation When at least one of the three reels of the reel unit 203 is rotating, the on / off device 2060 is turned on. Since the main board 200 controls the drive of the reel unit 203, the on / off device 2060 is turned on / off according to the state of the drive control.

(4) Outside business hours Information regarding a setting changeable time zone in which the setting can be changed is stored in advance in the setting change time zone storage unit 200d. The main board 200 compares the current time by the real-time clock 200c with the information in the setting change time zone storage unit, and turns on / off the on / off device 2060 based on the result of this comparison.

  A specific procedure executed by the CPU of the main board 200 in (4) above will be described with reference to the flowchart of FIG.

S30: The power switch 2051 of the power supply unit 205 is turned on.
S31: It is determined whether or not to set a setting change time zone. For example, the setting cannot be changed during business hours.
S32: 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 200d. The contents of the setting change unavailable time zone will be described in detail later.

S33: When the setting change time zone is set, the current time is acquired from the real-time clock 200c, and it is determined whether the current time is the setting change impossible time zone or the setting change time zone. Since the current time can be specified by the real-time clock 200c, the main board 200 compares this time with the time preset in the setting change time zone storage unit 200d.

S34: If the current time is within the setting changeable time zone, the on / off device 2060 is turned on.
S35: If the current time is within the setting change impossible time zone, the on / off device 2060 is turned off.

  9 to 12 are explanatory diagrams showing an example of setting of a setting change time zone table stored in advance in the setting change time zone storage unit 200d, that is, a setting change impossible time zone and a setting changeable time zone.

  Normally, setting changes are made before the hall starts or after it closes. Therefore, as shown in FIG. 9, the opening time of the hall corresponding to the opening of the hall and its surroundings are set in the setting change impossible time zone A, and other times are set in the setting changeable time zone B.

  FIG. 10 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.

  FIG. 11 is a diagram illustrating a case where a 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. 11 is a day of temporary closure, 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.

  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.

  According to the first embodiment of the invention, the setting key switch power supply 2061 that supplies current to the setting key switch 2054 and the current supply from the setting key switch power supply 2061 to the setting key switch are turned on or off, or via the switch. Since the on / off device 2060 for turning on / off the grounding of the current is provided, the setting key switch 2054 can be validated only at a predetermined timing. When the on / off device 2060 is off, the setting change process is not started even if the setting key switch 2054 is illegally operated. Even if the terminal of the setting key switch 2054 is improperly shorted to the power supply or ground, the setting change process is not started because the power supply is turned off. Accordingly, unauthorized setting changes can be prevented.

Embodiment 2 of the Invention
FIG. 13 shows a conceptual diagram of connection of the setting key switch 2054 according to the second embodiment of the invention. FIG. 13 corresponds to FIG. 5A, and the same or corresponding parts are denoted by the same reference numerals.

  A setting key switch signal source 2062 outputs a specific type of signal (for example, an analog signal having a specific voltage and a specific frequency, a digital signal that becomes 0 or 1 at random), and the like. In order to generate a digital signal that becomes 0 or 1 at random, for example, a shift register that performs parallel-serial conversion is prepared, and a random number for lottery generated by the main board 200 is loaded thereon, and a specific clock signal is generated. Then, the contents of the shift register (random numbers) may be output.

  Reference numeral 200 e denotes a comparator that compares a signal from the setting key switch 2054 with a specific type of signal from the setting key switch signal source 2062. Based on the output of the comparator 200e, the main board 200 starts a setting change process. The comparator 200e is configured by, for example, a combination of a filter that passes only a specific frequency and an analog comparator, or an exclusive OR (XOR) gate. In order to compare a digital signal that becomes 0 or 1 at random, an exclusive OR (XOR) of the signal from the setting key switch 2054 and the output of the setting key switch signal source 2062 is obtained and is continuously set to 0. What is necessary is just to determine whether it is.

  In FIG. 13, the output of the setting key switch signal source 2062 is input to the comparator 200e and also input to the setting key switch 2054 via the on / off device 2060. An ON / OFF device 2060 such as a relay is connected in series between the setting key switch signal source 2062 and the setting key switch 2054. When the setting key switch 2054 is turned on (ON), the on / off device 2060 must be turned on in order for the signal of the setting key switch signal source 2062 to be input to the main board 200.

  In the second embodiment of the invention, a setting key switch signal source 2062 for outputting a specific type of signal is provided instead of the setting key switch power source 2061. In the second embodiment of the invention, the comparator 200e compares the signal from the setting key switch 2054 with a specific type of signal from the setting key switch signal source 2062, thereby determining whether the setting key switch 2054 is on or off.

  When the on / off device 2060 is off or the setting key switch 2054 is off, the comparison result in the comparator 200e is inconsistent (one input of the comparator 200e is the signal of the specific type, but the other is no signal) (Typically no change at L or H level). In this case, the main board 200 does not perform setting change processing. When the on / off device 2060 is on and the setting key switch 2054 is on, the comparison results in the comparator 200e are the same. At this time, the main board 200 performs setting change processing.

  The second embodiment of the invention has the same effects as the first embodiment.

  In Embodiments 1 and 2, the setting key switch 2054 is turned on / off by the on / off device 2060 (valid / invalid is switched), but the present invention is not limited to this. It can also be applied to other switches used when changing settings. For example, instead of the setting key switch 2054, a setting change / reset switch 2055 or a start switch 134 can be used.

  Specifically, an on / off device 2060 may be connected to a setting change / reset switch 2055 used when changing the setting value. Since the connection is the same as that of the setting key switch 2054, the description thereof is omitted.

  An on / off device 2060 may be connected to the start switch 134 used when determining the set value. An example of the connection is shown in FIG. The on / off device 2060 is provided between the start switch 134 and the main board 200.

  When applied to the setting change / reset switch 2055 and the start switch 134, the same operational effects as those of the first and second embodiments of the invention can be obtained.

  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.
