Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gaming machine provided with a control device that performs a lottery due to establishment of a lottery condition and puts a game state in which a game is advantageous for a player when the result of the lottery is a win.

[0002]

2. Description of the Related Art For example, a gaming machine such as a pachinko machine is provided with a control device for controlling various electric devices mounted on the gaming machine. This control device is caused by establishment of a predetermined lottery condition. A lottery is performed, and when the result of the lottery is a win, various electric equipments are controlled so that a game state advantageous to the player is obtained. As a lottery method performed by this control device, a lottery using a random number is generally performed. That is, the control device is updated every predetermined time and generates a random number so as to circulate within a preset numerical range. Then, the random number generated when the lottery conditions are satisfied is acquired, and the gaming state advantageous to the player is determined by whether or not the acquired random number is a winning value (a numerical value appropriately determined within a set numerical range). Decide whether or not to do it. For the sake of concrete explanation, it is assumed that the random number is updated every 4 ms and is programmed so as to circulate within the numerical range of 0 to 249. When the control device starts the random number program, the initial value (normally 0
Is set) and the random number is generated every 4 ms while the random number is updated. When the random number reaches 249, the random number is returned to 0, and the random number is updated in the same manner as before. Then, when the lottery condition is satisfied, a random number generated at that time is acquired, and when the random number is a winning value (for example, 7), a gaming state advantageous to the player (for example, a specific winning device is opened). State).

In the lottery method using such a random number, the hit value of the random number is usually a constant value. Therefore, FIG. 7 (a)
As shown in, a program (for example, from 0 to 24 in sequence) so that the random number generated by the controller always returns to a constant initial value
9 is updated, and 0 to 249 are circulated after the next cycle)
Assuming that the random number is the initial value, the time (t1, t2) from the initial value of the random number to the generation of the hit value is always a constant time. Therefore, there is a case where a fraudulent act (a so-called aiming action of a hit random number using a sensation machine (metronome) or the like) is performed by utilizing this fact. Based on such an actual situation, an initial value changing type random number system has been developed which changes the initial value of the random number generated by the control device at every predetermined cycle. Also in the case of the initial value changing type random number system, the above-mentioned FIG.
Similar to the example shown in (a), the random number is updated every predetermined time and circulates within a preset numerical range. However, in the case of the initial value changing type random number system, when the random number circulates within a set numerical range for a predetermined period (for example, one period), it is programmed to change the initial value for starting the next update. . For the sake of concrete explanation, it is assumed that the random number is updated and circulated every 4 ms within the numerical range of 0 to 249, and the initial value is changed every one cycle (one cycle), as in the above example. . As shown in FIG. 7B, in the case of the initial value changing random number method, the random number is 0 to 24 in the first cycle.
9 cycle, the initial value is changed in the next cycle (for example,
0 to 150), and the random number circulates 150 to 249 and 0 to 149. Therefore, according to the initial value changing type random number method, the time from the initial value of the random number to the generation of the hit value changes with the change of the initial value (in the example of the figure, from t1 t2), it becomes possible to prevent the above-mentioned fraud.

[0004]

[Problems to be Solved by the Invention] However, even if the initial value changing type random number system is used, there are cases where fraud cannot be prevented. That is, also in the initial value changing type random number system, the initial value becomes a fixed value (usually 0) in the process of the first cycle when the control device starts the random number program. Therefore, if the random number program is forcibly initialized and the program is restarted, the initial value at the time of restart is always a fixed value. That is, the time when the random number becomes the hit value after the signal for initializing the random number program is input to the control device is always a constant time. Therefore,
Even with the initial value change type random number method, by forcibly restarting the random number program performed by the control device, it is possible to know the timing at which the random number becomes the winning value, and it is possible to act fraudulently. Becomes

The present invention has been made in view of the above circumstances, and an object thereof is to provide a gaming machine capable of preventing damage by fraudulent activity by facilitating discovery of fraudulent activity. .

[0006]

[Means for Solving the Problem, Action and Effect] In order to solve the above-mentioned problems, a gaming machine according to claim 1 is provided with a production device that performs a game production, and a control device that controls the production device. Is to make the production device perform the game production according to the progress of the game, and obtain a random number due to the establishment of the lottery condition, and when the obtained random number is the winning value, the game state is advantageous to the player. In the gaming machine, the random number acquired by the control device is sequentially updated from the initial value at predetermined time intervals and circulates within a preset numerical range, and the initial value is updated at predetermined time intervals and changed. The control device performs one of the game effects among the game effects performed according to the progress of the game to the effect device when the initialization signal for initializing the random number program is input. Prog to let Have been ram. Here, the "initialization signal" may be any signal as long as it is a signal for initializing and restarting the random number program, for example, a power failure signal (signal for starting power failure processing), a clear signal (power failure). A signal for clearing the information sometimes stored in the storage device) or the like corresponds to the initialization signal. In the gaming machine, when the initialization signal is input to the control device, the effect device performs a predetermined game effect. Therefore, it becomes possible for the hall clerk or the like to discover that the initialization signal has been input to the control device by the game effect performed by the effect device, and it is possible to prevent damage due to cheating. Further, since the notification that the initialization signal has been input is shared with one of the game effects performed by the effect device according to the progress of the game, it is not necessary to provide a new device for notification, and The number of man-hours for program development for notification can be reduced.

In the above gaming machine, it is preferable that the game effect that is performed when the initialization signal is input to the control device is a game effect that appears less frequently. According to such a configuration, the fact that the initialization signal has been input by the game effect having a low appearance frequency is notified, so that it is possible to easily detect fraudulent activity by a hall clerk or the like. Here, "a game effect having a low appearance frequency" refers to a game effect that does not appear in a normal game progression and is performed when a special condition is satisfied. For example, it corresponds to a game effect performed when the random number acquired by the control device is a winning value. In addition, when there are a plurality of game effects that are performed when the winning value is reached, one game effect may be selected from those game effects.

The control device described above includes a main control unit that performs a random number acquisition process and a command output process for instructing a game effect, and a sub-control unit that controls the effect device based on the output command. It may be composed of In such a case, modify the program of the sub control unit so as to invalidate the notification command output from the main control unit (command output to the sub control unit to perform the game effect when the initialization signal is input). Therefore, it is possible to make it impossible to detect fraud. However, according to the above-mentioned gaming machine, it is possible to detect fraud even in such a case. That is, in the above configuration, when the initialization signal is input to the main control unit, the main control unit outputs a command to the sub control unit to perform a predetermined game effect, and the command causes the sub control unit to perform a predetermined game effect. Let the performance device do it. Therefore, when the command output from the main control unit to the sub control unit (command for injustice notification) is invalidated, the game effect that should be performed in the normal game state is not performed. Therefore,
Since the game effect that should be performed is not performed, it is possible to detect an abnormality (illegal) in the game machine.

[0009]

(Mode 1) The above-mentioned gaming machine is equipped with an image display device that displays an image in accordance with the progress of the game, a voice output device that outputs a sound, and a lamp device that emits light as a production device. When the initialization signal is input to the control device, at least one of these effect devices performs a predetermined game effect.

[Table 1]

In the power supply device 100, a voltage transformer 106 for supplying electric power of a predetermined potential to each electric device assembled in the pachinko machine 10 and a power failure detector 104 for detecting power interruption.
In addition, various switches such as the power switch 108 and the initialization switch 102 are provided. The voltage transformer 106 is
As shown in FIG. 3, the main controller 200 and the prize ball controller 3
00, the sound control section 400, and the display control section 500 are supplied with electric power of a predetermined potential, while various electric devices (the winning ball sensor 5
0, starting port sensor 32, symbol display 22, solenoid 3
5, the prize ball device 40, the speaker 48, etc.) is supplied with electric power of a predetermined potential. That is, the voltage transformer 106 rectifies and smoothes the AC input from the Hall AC power supply with a rectifier circuit, converts the rectified and smoothed DC power supply into a voltage suitable for each electrical equipment, and supplies the voltage. . In addition, in FIG. 3, the main control unit 200 and the prize ball control unit 30 are shown.
Power supply lines to devices other than 0 are not shown. The power outage detection unit 106 continuously monitors the AC input from the AC power supply in the hall, determines that the power supply is cut off when the waveform continues to be missing for a predetermined period, and determines the main control unit 200 and the prize ball. A power failure signal is output to the control unit 300. The power switch 108 is a switch for operating ON / OFF of the AC input from the AC power supply in the hall, and is provided on the back surface of the pachinko machine as shown in FIG. The voltage transformer 106, the power failure detector 104,
The configuration of the power switch 108 may be the same as that of a conventionally known pachinko machine, and does not particularly characterize the present invention, so a detailed description thereof will be omitted.

The initialization switch 102 is a switch operated by a hall clerk at the start of business after a power failure recovery, and is operated to initialize the processing of the main control unit 200 and the prize ball control unit 300 described above. . The initialization switch 102 is provided on the back surface of the pachinko machine (specifically, on the substrate 120 of the power supply device 100) as shown in FIG. The initialization switch 102 will be described in detail with reference to FIG. The initialization switch 102 is a so-called reed switch of a type that closes the contacts when pressed. Specifically, as shown in FIG. 4B, the power supply device 1
00 is a push-type switch disposed on the substrate 120. The initialization switch 102 is housed in a casing 110 made of a plastic material having elasticity. As shown in FIG. 4A, the casing 110 is provided with a pressing portion 114 at a position facing the initialization switch 102, and cutouts 112 are provided in three directions around the pressing portion 114. On the inner surface of the pressing portion 114 (the portion facing the initialization switch 102),
A contact portion 116 that projects toward the initialization switch 102 is formed. The initialization switch 102 having such a configuration is turned on.
To enter the state, the hall clerk or the like presses the pressing portion 114 onto the substrate 1.
Press on the 20 side. When the pressing portion 114 is pressed toward the substrate 120 side and deformed as shown in FIG. 4C, the contact portion 116.
Pushes the initialization switch 102, and the initialization switch 102
Turns on. In order to turn off the initialization switch 102, the pressing of the pressing portion 114 is released. As a result, the contact portion 116 is separated from the initialization switch 102 by its elasticity, and the contacts of the initialization switch 102 are opened to be in the OFF state (state of FIG. 4B). It should be noted that the pressing portion 114 is, as shown in FIG.
By being a tlitchi without protruding from the surface of
The pressing portion 114 is prevented from being accidentally pressed.

The relationship between the initialization switch 102 configured as described above and each control unit (in the present embodiment, the main control unit 200 and the prize ball control unit 300) connected to the initialization switch 102 will be described. , FIG. 5 will be described. Figure 5
As shown in, the output signal of the initialization switch 102 is 2
It is input to each control unit via one buffer IC (indicated by A and B in the figure). As is clear from the circuit diagram shown in FIG. 5, when the initialization switch 102 is in the OFF state, the output signal of the initialization switch 102 becomes a high level signal.
A high-level signal is input to the control unit via one buffer IC. On the other hand, when the initialization switch 102 is in the ON state, the output signal of the initialization switch 102 becomes a low level signal, and the low level signal is input to the control unit via the two buffer ICs. Therefore, the main controller 20
A person who wants to initialize the random number program of 0 inserts an illegal board between the initialization switch 102 and the main control unit 200, and outputs an initialization signal from the illegal board to the main control unit 200. Become.

Next, the operation of the pachinko machine 10 constructed as described above when the power is cut off and when the initialization switch is operated (when the initialization signal is input) will be described. First, the operation when the power is cut off will be described. In the pachinko machine 10 according to the present embodiment, when the power supply to the pachinko machine 10 is cut off, the power failure detection unit 104 first determines whether or not the power shutdown has really occurred (a momentary power failure or not). To do. When it is determined that the power is shut down (when there is no AC input for a predetermined time), the main control unit 200
(At the same time, a power failure signal is output to the prize ball control unit 300).
When the main control unit 200 receives the power failure signal, the C
The power failure process is started by the PU 202. That is, RA
By prohibiting access to the M202b, the stored contents (for example, probability variation information) stored in the RAM 202b at that time are retained. Similarly, in the prize ball control unit 300, the RAM 302b is also executed by the CPU 302.
Access is prohibited, and the stored contents (for example, ball payout information and the like) stored in the RAM 302b are retained.

Next, the operation of the pachinko machine 10 when the initialization switch is operated will be described. In the pachinko machine 10 according to the present embodiment, as is apparent from the above, the RAM 202b and 302b provided in the main control unit 200 and the prize ball control unit 300 retain the stored contents when the power is cut off. . These RAMs 202b, 30
The memory contents stored in 2b need to be retained when the player playing the game at the time of power off plays the same pachinko machine even after the power is restored, but when the game is played at the time of power off It is not preferable to retain the stored contents when the player who has returned while the power is off. For example,
When the business starts with the probability variation information stored in the RAM 202b of the main control unit 100 held, the pachinko machine restarts the game in the probability variation state from the beginning, and other pachinko machines placed in the hall. There will be inequity with the players who play on the pachinko machines, and it will also be a disadvantage on the side of the hall. The RAM 30 of the prize ball control unit 300
When the business is started with the ball payout information stored in 2b being stored, since the prize balls are paid out even when no one is sitting at the start of the business, the hall clerk is paid out. It takes time to collect the pachinko balls. Therefore, in the pachinko machine 10 of the present embodiment, by operating the initialization switch 102, the RAM 202b,
It is possible to clear the stored contents of 302b.

The processing of the main controller 200 and the sound controller 400 when the initialization signal is input will be described below with reference to FIG. First, the process of the main controller 200 when the initialization signal is input will be described with reference to the flowchart shown in FIG. When the initialization signal is input, the main control unit 200 first initializes the CPU 202 (S1).
0). At this time, the random number program executed by the CPU 202 is also initialized. Then, a command for notifying that the initialization signal has been input (a command for instructing a big hit opening sound) is output to the sound control unit 400 (S12). The processing in the sound control unit 400 when receiving this command will be described later. Step S1
At 4, the stored contents stored in the RAM 202b are cleared. RAM202 by the process of step S14
When the stored contents of b are cleared, the main control unit 200
Outputs a command for displaying a predetermined screen (default screen) on the symbol display 22 to the display control unit 500 (S16). Therefore, the display control unit 500 performs processing for displaying the default screen on the symbol display 22 based on the reception of the command output in step S18. When these processes are completed, the contents stored in the RAM 202b are cleared, and the process proceeds to the main process which is a normal game process (S22). When shifting to this game processing, the above-mentioned random number program is restarted from the initial state to generate a random number, and the symbol display 22, the speaker 48, and the lamps are operated according to the progress of the game.

Next, the processing of the sound control unit 500 which receives the command output from the main control unit 200 will be described with reference to FIG. 6 (b). As shown in FIG. 6B, when the command is received, the sound control unit 500 first analyzes the received command (S20). Specifically, it analyzes which sound effect the command received is a command instructing (see Table 1). By this command analysis process, the type of sound generated from the speaker 48 (a big hit opening sound in this embodiment) is determined, and then a voice corresponding to the analyzed command is output from the speaker 48 (S22).

As is clear from the above description, in the pachinko machine of this embodiment, when the initialization signal is input to the main control unit 200, the big hit opening sound is output from the speaker 48. Therefore, if a fraudulent input of the initialization signal to the main control unit 200 is performed, the big hit opening sound is frequently output although the big hit is not made. Therefore, a hall clerk or the like can find out that an abnormality (illegal) has occurred in the gaming machine. In particular, the jackpot opening sound is a sound that is output when the result of the random number lottery is a winning value, and its appearance frequency is low, so the hall clerk, etc. can easily notice that the gaming machine is abnormal. You can In the gaming machine described above, the main control unit 200 outputs a command to the sound control unit 400, and the sound control unit 500 drives the speaker 48 to output a notification sound (big hit opening sound). For this reason,
It is conceivable that the sound control unit 400 may further act as an illegal act that invalidates the command output from the main control unit 200 when the initialization signal is input. However, in this embodiment, since the notification is made by the sound effect generated in the game effect, if the illegality for invalidating the command is activated, the sound effect is not output in the normal game state. Therefore, since the sound effect that should be output is not output, it is possible to notice the abnormality of the pachinko machine. Furthermore, since the notification sound for notifying that the initialization signal has been input is shared with the sound effect output as the game effect, it is possible to use an existing command as the command transmitted from the main control unit to the sound control unit. it can. Therefore, the sound control unit can use the existing device, processing program, and the like as they are.

In the above-mentioned embodiment, the hall clerk is notified by outputting a notification sound (big hit opening sound) from the speaker 48 that the initialization signal is input to the main controller 200. The present invention is not limited to such an example, and may be notified by operating a lamp (light emitting device), a pattern display 22 and the like, which are separately provided in the pachinko machine. In this case, it is possible to use the light emission effect or the symbol display effect performed at the time of a big hit.
Further, the above-described embodiment is an example in which the technique of the present invention is applied to a pachinko machine, but the gaming machine to which the present invention can be applied is not limited to the pachinko machine, and is advantageous to the player depending on the result of the lottery using random numbers. It can be applied to various game machines in different game states. For example, it can be applied to a slot machine or the like.
