Description

The present invention relates to a gaming machine.

Conventionally, there is known one that can memorize that the front door has been opened and closed and can confirm the stored historical data (Patent Document 1).

Japanese Unexamined Patent Publication No. 2003-159465

However, if all the facts that the front door has been opened and closed are memorized, a person who illegally opens and closes the front door opens and closes the front door unnecessarily, increases the number of memorized cases, and causes the front door when an illegal act is performed. There was a problem that the opening and closing was overlooked.
In addition, especially when the number of stored items and the number of displayed items are limited, the opening and closing of the new front door is memorized and displayed, so that the opening and closing of the front door itself when an illegal act is performed is erased or displayed. It was also possible that it would not be done.

Therefore, in the present invention, the fraudulent act is performed by memorizing that the state of the front door has changed when the state of the front door has changed during the time when the fraudulent act is likely to have been performed. It is an object of the present invention to provide a game machine capable of memorizing only a change in the state of the front door, which is highly likely.

A display device capable of displaying a list is provided, and in the list display, the items are displayed side by side in the order of newest time, and when the number exceeds a predetermined number, the oldest one is not displayed, and the front door state storage means ( 330) refers to the time when the state of the front door (14) was changed last time, and the specified time must have elapsed from the time when the state of the front door (14) was changed last time. For example, the state of the front door (14) is not memorized regardless of the state of the front door (14), and the state of the front door (14) changes when the specified time has elapsed from the time when the state of the front door (14) changes. Then, referring to the previous state of the front door (14) that is memorized, if the state of the front door (14) has changed, the state of the front door (14) and the time are set to the front. It is memorized when the state of the door (14) changes, and the state of the front door (14) changes before the specified time elapses from the time when the state of the front door (14) changed last time. When the state of the front door (14) maintains the changed state when the specified time elapses, it is characterized in that it is stored when the specified time elapses.

This does not remember all the changes in the state of the front door (14), but only if the state of the front door (14) has changed during the time when the fraud is likely to have occurred. Provided is a gaming machine (10) capable of memorizing only the change in the state of the front door (14), which is highly likely to have been cheated, by memorizing the change in the state of the door (14). be able to.
In particular, when the number of stored items and the number of displayed items are limited, the person who commits the fraud repeatedly opens and closes the front door unnecessarily, so that the memory at the time of the fraud is erased or displayed. It is possible to prevent it from disappearing.

In addition, by promptly storing when the specified time elapses, the state of the front door (14) changes before the specified time elapses from the timing of the previous storage by the front door state storage means (330). Then, for example, when the door becomes "open" and the "open" state is maintained until the specified time elapses, the state stored by the front door state storage means (330) and the current state before the present. It is possible to minimize the period of time when there is a difference between the state of the door and the state of the door, and it is possible to update the history of the work normally performed by the clerk of the amusement shop without any particular operation.

Further, in the gaming machine (10) according to the present invention, the operation of the operating means is performed at least after the administrator of the gaming machine (10) opens the front door (14). It is characterized in that the key inserted into the keyhole provided inside 10) is rotated.

Further, the advantageous section control means 260 shifts from the “non-advantageous section” to the “advantageous section” when a predetermined combination is won by the combination lottery.

In addition, it is not limited to the case of shifting from a non-advantageous section to an advantageous section by winning a predetermined combination by a combination lottery, but a lottery executed when the winning combination is won (advantageous section transition lottery). Therefore, the transition may be made when it is determined to shift to the advantageous section.

(Transmission means 270)
The transmission means 270 is for transmitting a signal to the sub-control board 300.

(Sub-control board 300)
As shown in FIG. 8, the sub-control board 300 includes receiving means 310, effect control means 320, front door state storage means 330, and front door state display control means 340. Details of each means will be described later. The effect control means 320 may be divided into both the main control board 200 and the sub control board 300 instead of the sub control board 300.

With the above configuration, the sub control board 300 receives a signal from the main control board 200 and performs an effect as the game progresses.
Specifically, the sub-control board 300 outputs data that regulates the lighting and extinguishing of the LED to the LED drive circuit (not shown) for driving the effect lamp 78, and outputs sound from the speaker 72.

To execute.

Specifically, a plurality of images or videos (for example, "1") indicating the pressing order are displayed on the screen of the projector device 84 corresponding to the position of each stop switch 50 (specifically, the position of the rotating reel 62 corresponding to each stop switch 50). "2" "3") is displayed to notify the pressing order. After that, each time the stop switch 50 is operated, the part corresponding to the position of the operated stop switch 50 is erased (or changed to an image showing no order) in the image or video showing the pressing order.

(Front door state storage means 330)
The front door state storage means 330 uses the front door 14 when the state of the front door 14 changes regardless of the power supply state of the gaming machine, specifically, whether the second power supply device 43 is on or off. It is possible to memorize the state (open / closed) and the time when the state of the front door 14 changes in association with each other.
Here, as will be described later, the time stored by the front door state storage means 330 is the time when the state of the front door 14 changes and the time when the state of the front door 14 changes last time after the state of the front door 14 changes. This includes the case where the specified time, for example, 2 minutes, has elapsed from the time when the state of the door changes.

The front door state storage means 330 refers to the time when the state of the previous front door 14 is stored, and if the specified time has not elapsed from the time when the state of the front door 14 was changed last time, the previous door state storage means 330. I try not to remember regardless of the state of the door 14.
That is, when the front door 14 is opened and closed a plurality of times in a short time not exceeding a specified time, for example, 2 minutes, the memory is not stored.

Here, if the time when the state of the front door 14 was changed last time is not stored, that is, if the front door state storage means 330 is not stored due to RAM clearing or the like, the front door state storage means 330 is not stored for the first time regardless of the passage of the specified time. The time when the state of the door 14 changed is memorized.

Further, the front door state storage means 330 refers to the time when the state of the front door 14 was stored last time, and the state of the front door 14 is in a state where a specified time has elapsed from the time when the state of the front door 14 changed. When is changed, the state of the previous front door 14 that is memorized is referred to, and if the state of the front door 14 is changed, the state of the front door 14 and the time are changed to the state of the front door 14. I try to remember when it changes.
That is, if the specified time has elapsed, the time when the state of the front door 14 has changed is stored when the specified time has elapsed.

Further, the front door state storage means 330 refers to the time when the state of the previous front door 14 is stored and is stored before the specified time elapses from the time when the state of the previous front door 14 is changed. If the state of the front door 14 changes and the state of the front door 14 maintains the changed state when the specified time elapses, it is stored when the specified time elapses.
That is, if the state of the front door 14 has changed when the specified time has elapsed, it is stored when the specified time has elapsed.

Here, as will be described later, the time when the state of the front door 14 and the state of the front door 14 displayed on the liquid crystal display device 85 by the front door state display control means 340 changes is, for example, 10 cases. The state of the front door 14 and the time when the state of the front door 14 has changed, which exceeds 10 cases, are not displayed on the liquid crystal display device 85, but even if they are not erased from the front door state storage means 330 and are stored as they are. good.

(Front door status display control means 340)
The front door state display control means 340 uses the liquid crystal display device 85 to set the time when the state of the front door 14 and the state of the front door 14 stored by the front door state storage means 330 are changed by the operation of the operation means. The list is displayed in the order of newest.

In such a list display, the time is displayed in the order of newest time, and when the number of cases exceeds a predetermined number, for example, 10 cases, the oldest one is not displayed first.
In addition, the predetermined number of cases is not limited to 10, and the number of cases that can be displayed on the first page is 10 cases, and the number of cases that can be displayed on the second page is further 10 cases. It may be displayed as.

Further, the operation of the operating means is provided inside the game machine 10 at least after the manager of the game machine 10 (for example, a clerk of the game store where the game machine 10 is installed) opens the front door. The key (for example, the setting key) inserted into the keyhole (for example, the setting key switch 45) is rotated, but the operation is not limited to this, and any operation means that the player cannot operate. Just do it.

Further, the timing of displaying the state of the front door 14 by the front door state display control means 340 and the time when the state of the front door 14 has changed on the liquid crystal display device 85 is the state of the front door 14 by the front door state storage means 330. This is performed when the time when the state of the front door 14 changes is memorized, but the present invention is not limited to this.

For example, from the state in which the front door state display control means 340 causes the liquid crystal display device 85 to display the state of the front door 14 and the time when the state of the front door 14 has changed, the liquid crystal display is performed by some operation by the clerk of the amusement shop. Displaying the state of the front door 14 and the time when the state of the front door 14 has changed when the device 85 is changed to display other information, for example, information on the history of changing the set value of the winning combination lottery. Is permitted, and the state of the front door 14 and the time when the state of the front door 14 has changed may be reflected when the liquid crystal display device 85 is displayed again.

Further, for example, from the state in which the liquid crystal display device 85 displays the state of the front door 14 and the time when the state of the front door 14 is changed by the front door state display control means 340, the clerk of the game store can play the game. When changing to the state, it is allowed to display the state of the front door 14 and the time when the state of the front door 14 changed, and again the state of the front door 14 and the time when the state of the front door 14 changed. It may be reflected when displaying on the liquid crystal display device 85.

In this way, by delaying the display on the liquid crystal display device 85 from the timing of storage by the front door state storage means 330, it becomes difficult for an unauthorized person to confirm the information stored in the front door state storage means 330. It becomes possible.

(Example of memory of front door state and time by front door state storage means)
Next, an example of storing the state and time of the front door 14 by the front door state storage means 330 will be described with reference to FIG.

FIG. 9 is a timing chart showing the timing of storing the state and time of the front door 14 by the front door state storage means 330.
FIG. 9 shows a state in which the front door state storage means 330 is stored in the “closed” state in which the front door 14 is closed. Further, the downward arrow in FIG. 9 indicates the timing at which the front door state storage means 330 is stored. Further, the arrows in the left-right direction in FIG. 9 indicate the passage of a specified time, for example, 2 minutes from the timing when the front door state storage means 330 is stored.

First, in FIG. 9A, the state of the front door 14 changes to be “open” before the specified time elapses from the timing of the previous storage by the front door state storage means 330, and the “open” is obtained. It shows the case where the state of is maintained until the specified time elapses. In this case, since the state of the front door 14 stored by the previous front door state storage means 330 has changed (closed and open) when the specified time has elapsed, the front door is moved forward when the specified time elapses. The door state storage means 330 stores the state of the front door 14 and the time when the specified time has elapsed.

In FIG. 9B, the state of the front door 14 changes to become “open” before the specified time elapses from the timing of the previous storage by the front door state storage means 330, and the “open” state is shown. Is not maintained until the specified time elapses, and when the specified time elapses, it is in the "closed" state. In this case, since the state of the front door 14 stored by the previous front door state storage means 330 has not changed (closed and closed) when the specified time has elapsed, the front door state storage means 330 is used to move forward. The state of the door 14 and the time when the specified time has elapsed are not memorized. Further, in FIG. 9B, “x” indicates that the front door state storage means 330 does not store the memory.

In FIG. 9C, the state of the front door 14 changes a plurality of times before the specified time elapses from the timing of the previous storage by the front door state storage means 330, resulting in “open”, “closed”, and “open”. , "Closed", "Open", "Closed", "Open", and the last "Open" state is maintained until the specified time elapses. In this case, since the state of the front door 14 stored by the previous front door state storage means 330 has changed (closed and open) when the specified time has elapsed, the front door state storage means 330 is used to move forward. The state of the door 14 and the time when the specified time has elapsed are stored.

FIG. 9D shows that the state of the front door 14 does not change until the specified time elapses from the timing of the previous storage by the front door state storage means 330, and the state of the front door 14 after the specified time elapses. Shows the case where is changed to "open". In this case, when the specified time elapses, the state of the front door 14 stored by the previous front door state storage means 330 has not changed (closed and closed), but then changed from the state of the front door 14. (Closed and opened), the front door state storage means 330 stores the state of the front door 14 and the time when the state of the front door 14 changes.

As shown in FIG. 9, instead of memorizing all the changes in the state of the front door 14, only when the state of the front door 14 has changed during the time when there is a high possibility of cheating. By memorizing the change in the state of the front door 14, it is possible to provide the game machine 10 capable of memorizing only the change in the state of the front door 14 in which there is a high possibility that an illegal act has been performed.
In particular, when the number of stored items and the number of displayed items are limited, the person who commits the fraud repeatedly opens and closes the front door unnecessarily, so that the memory at the time of the fraud is erased or displayed. It is possible to prevent it from disappearing.
Further, by promptly storing the memory when the specified time has elapsed, as shown in FIG. 9A, the front door 14 is stored before the specified time elapses from the timing of the previous storage by the front door state storage means 330. When the state of is changed to "open" and the "open" state is maintained until the specified time elapses, the state stored by the front door state storage means 330 and the current front door It is possible to minimize the period in which there is a difference between the state and the state, and it is possible to update the history of the work normally performed by the clerk of the game store without any particular operation.

(Example of display by front door status display control means)
Next, with reference to FIG. 10, an example of a list display of the state of the front door 14 stored in the front door state storage means 330 by the front door state display control means 340 and the time when the state of the front door 14 changes will be described. To do.

The front door state display control means 340 lists the state of the front door 14 stored in the front door state storage means 330 on the liquid crystal display device 85 and the time when the state of the front door 14 changes as shown in FIG. indicate.
Here, the liquid crystal display device 85 displays the images in order of newest time.
Then, when the number of cases exceeds a predetermined number, for example, 10 cases, the oldest one is not displayed.

For example, the NO "1" displayed at the top is the newest time, and the NO "10" displayed at the bottom is the oldest time.
Then, when the front door state storage means 330 stores the state of the front door 14 and the time when the state of the front door 14 changes, the NO "1" displayed at the top is the second NO. The position is moved to the position of "2", and the NO "10" displayed at the bottom is no longer displayed.

When NO "1" is memorized, the front door state storage means 330 changes the state of the front door 14 by referring to the state and time of the front door 14 of the previous NO "2". It is determined whether or not the door 14 has passed, and whether or not the specified time has elapsed, and when the state of the front door 14 has changed and the specified time has passed, NO "1" is stored.

Here, when the example shown in FIG. 10 is applied to the example shown in FIG. 9 described above, the example when storing NO “5” (in the case of NO “6” to NO “5”) is shown in FIG. 9 (a). ) Or (c), and the others are the examples of FIG. 9 (d).

(Explanation of the flow of storage processing by the front door state storage means using FIG. 11)
Based on the flowchart shown in FIG. 11, a typical example of the storage process of the change in the state of the front door 14 executed by the front door state storage means 330 and the time when the state of the front door 14 changes will be described.

In step S20, whether or not the door opening / closing switch 19 has been operated by the sub control board 300, that is, the door opening / closing switch 19 is changed from on (closed) to off (open) or from off (open) to on (closed). It is determined whether or not it has become. If it is determined that the door opening / closing switch 19 has been operated, the process proceeds to the next step S21. If it is not determined that the door opening / closing switch 19 has been operated, step S20 is performed again.

In step S21, it is determined whether or not a predetermined time, for example, 2 minutes, has elapsed from the time when the state of the front door 14 stored by the previous front door state storage means 330 has changed. If it is determined that the specified time has elapsed, the process proceeds to the next step S22, and if it is not determined that the specified time has elapsed, step S21 is performed again.

Whether or not the state of the front door 14 has changed from the state of the front door 14 stored by the previous front door state storage means 330 in step S22 by the operation of the door opening / closing switch 19 determined in this step S20. Is determined. That is, it was turned off (open) when the state of the front door 14 stored by the previous front door state storage means 330 was on (closed), or before it was stored by the previous front door state storage means 330. When the state of the door 14 is off (open), it is determined whether or not the door 14 is turned on (closed). If it is determined that the state of the front door 14 has changed, the process proceeds to the next step S23, and if it is not determined that the state of the front door 14 has changed, step S22 is performed again.

Here, the processing of step S21 and the processing of step S22 are such that the current state of the front door is always memorized, so that the order of processing is reversed, that is, the processing of step S22 is performed first. It may be executed, and the process of step S21 may be executed after the process of step S22 is executed.

In step S23, the front door state storage means 330 stores the state and time of the front door 14. Then, the process ends.

The present invention is not limited to the above-described embodiment, and various modifications other than those described above can be made without departing from the spirit of the present invention.

As described above, the present invention has the following effects.
The present invention does not memorize all the changes in the state of the front door (14), but only when the state of the front door 14 has changed during the time when there is a high possibility of cheating. By memorizing that the state of 14 has changed, it is possible to provide the gaming machine 10 that can memorize only the change in the state of the front door 14 that is likely to have been cheated.
In particular, when the number of stored items and the number of displayed items are limited, the person who commits the fraud repeatedly opens and closes the front door unnecessarily, so that the memory at the time of the fraud is erased or displayed. It is possible to prevent it from disappearing.

Further, by promptly storing the memory when the specified time has elapsed, as shown in FIG. 9A, the front door 14 is stored before the specified time elapses from the timing of the previous storage by the front door state storage means 330. When the state of is changed to "open" and the "open" state is maintained until the specified time elapses, the state stored by the front door state storage means 330 and the current front door It is possible to minimize the period in which there is a difference between the state and the state, and it is possible to update the history of the work normally performed by the clerk of the game store without any particular operation.

Further, the present invention further confirms the information stored in the front door state storage means 330 by a person who commits fraud, provided that the operation cannot be performed by a player other than the clerk of the game store. It is possible to provide a game machine 10 that can be made difficult.
