Description

  The present invention relates to a gaming machine having a mechanism for detecting opening and closing of a front door of a gaming machine such as a slot machine.

  Conventionally, in gaming machines, there has been a case in which a fraudulent act that illegally operates various devices provided in the housing is performed. In order to prevent such illegal acts, the gaming machine is provided with a sensor such as a mechanical contact switch or a photo sensor on the front door. There is something that has been announced to open.

  In addition, as disclosed in Patent Document 1, a gyroscope is installed on the front door that opens and closes the opening on the front surface of the housing, and the open / closed state of the front door is determined based on the rotation angle detected by the gyroscope. is there.

JP 2010-99404 A (see paragraphs 0053 to 0062, FIGS. 3 to 5)

  However, when the above-described mechanical contact switch or photosensor is used, the opening of the front door may not be reliably detected by using a jig that invalidates the sensor. Specifically, in the case of the above-mentioned mechanical contact switch, the front door is closed when the switch is on (hereinafter referred to as the closed state), and the front door is open when the switch is off (hereinafter referred to as the following). If the switch is kept turned on by an incorrect jig when it is determined that the sensor is open, the sensor will not turn off, but will remain on even though the front door is open. As a result, the front door is not determined to be in an open state, and during that time, illegal acts on the equipment inside the gaming machine may be performed.

  In the photosensor, the light from the light emitting unit is blocked by a light blocking member or the like and is not received by the light receiving unit, and the closed state is determined. The light is received without being blocked by a light blocking member or the like is determined as an open state. However, if a light-shielding member different from the original light-shielding member is improperly inserted and the state is always misrecognized as a closed state, the front door is detected by the sensor even though the front door is determined to be closed. May be in an open state, and during that time, there is a risk that cheating can easily be performed inside the gaming machine.

  Further, when a gyroscope is used as in the gaming machine described in Patent Document 1, in order for the gyroscope to detect the rotation angle, vibration and acceleration applied to the object are required, but the front door is opened slowly. In such a case, since the gyroscope does not react, it is impossible to detect a change in the rotation angle of the front door that is slowly opened, and it may not be possible to detect the opening of the front door.

  Therefore, the present invention has been made in view of the above-described problems, and an object of the present invention is to provide a gaming machine that can reliably detect the opening and closing of the front door and prevent fraud.

In order to achieve the above object, the present invention provides a gaming machine including a housing having an opening on a front surface and a front door provided on the housing to open and close the opening. The azimuth detector that detects the direction of the magnetic field and detects the azimuth angle, and the front detected by the azimuth detector when there is a specific operation for turning the door key of the front door in a direction opposite to the direction of turning when unlocking. Based on the reference azimuth storage means for storing the azimuth of the door as a reference azimuth, the current azimuth of the front door detected by the azimuth detector and the reference azimuth stored by the reference azimuth storage means Te, a closing determining means for determining the opening and closing state of the front door, when the front door by the closing determination means determines that the open state, and a notification means for notifying the open state of the front door The opening / closing judgment means In addition to the determination of the open / closed state of the front door, the difference between the current azimuth angle of the front door and the reference azimuth angle stored by the reference azimuth angle storage means is an opening range from the closed state of the front door in advance. When it is within the predetermined range, it is determined that the specific operation is performed in the closed state of the front door, and when the specific operation is not within the predetermined range, the specific operation is not in the closed state of the front door. When it is determined that the notification is performed, in addition to the notification of the open state of the front door, the opening / closing determination unit determines that the specific operation is performed when the front door is not closed. The fact is notified (claim 1).

  The “azimuth detector” is an object that detects an angle with respect to an azimuth with reference to true north in the direction of geomagnetism such as an electronic compass as an azimuth angle. Moreover, the magnetic sensor which can detect an azimuth using not only geomagnetism but magnetism may be used. Here, the “azimuth angle” represents a relationship with a reference azimuth using geomagnetism. Further, the “notification means” may be any means for notifying that when the opening / closing determination means determines that the front door is in an open state. For example, an effect lamp, a liquid crystal display, a speaker, etc. Applicable.

  Further, the open / close determining means has the front door open when the current azimuth angle of the front door detected by the azimuth detector is different from the reference azimuth angle stored by the reference azimuth angle storage means. It is good to judge (Claim 2).

  The open / close determination means includes derivation means for deriving a difference between the current front door azimuth angle detected by the azimuth detector and the reference azimuth angle stored by the reference azimuth angle storage means. It may be determined that the front door is open when the derivation result by the means reaches a predetermined threshold (claim 3).

  Further, the reference azimuth angle storage means may store the reference azimuth angle on condition that there is a specific operation excluding the unlocking operation of the front door by a door key.

According to the first aspect of the present invention, since the change in the azimuth angle of the front door can be accurately detected by the azimuth detector, it is possible to detect a minute movement of the front door, and to open and close the front door. The state can be detected reliably. In addition, since the orientation detector detects the direction of the magnetic field such as the geomagnetism, it is almost impossible to bend the magnetic field lines in an unauthorized manner, and an incorrect jig as in the case of using a conventional photosensor is used. Therefore, it is possible to provide a gaming machine that is less susceptible to detection interference due to and that can prevent fraud. Furthermore, in the gaming machine described in Patent Document 1, in order for the gyroscope to detect the rotation angle, vibration and acceleration applied to the object are necessary, and the gyroscope reacts when the front door is opened slowly. The opening of the front door may not be detected. However, by using an azimuth detector that detects the direction of a magnetic field such as geomagnetism, it is possible to reliably detect the opening of the front door without the need for vibration or acceleration. In addition, direction detection on the condition that there is a reset operation (specific operation) to turn the door key held only by those who are in the position of managing gaming machines such as store clerk in the direction opposite to the direction to turn when unlocking The reference azimuth angle by the body is stored in the reference azimuth angle storage means. In this way, it is possible to prevent the azimuth angle that is not the original reference azimuth angle from being illegally stored by an outside party unrelated to the game store that does not have the door key, and the front door is always closed normally. The reference azimuth angle by the azimuth detector at the reference position can be stored in the reference azimuth angle storage means, so that it is possible to prevent an injustice from occurring on the reference azimuth angle itself that is a reference for opening / closing determination of the front door. Further, the open / close determining means, in addition to determining the open / closed state of the front door, determines whether the difference between the current front door azimuth and the reference azimuth angle stored by the reference azimuth angle storage means is the front door closed state. If the predetermined range is not within the predetermined range as the opening range, it is determined that the specific operation was performed when the front door was not closed. In this way, not only whether the front door is opened or closed, but also whether the reference azimuth is stored in the closed state of the front door, that is, whether the reference azimuth is stored in a normal state. Can also be done.

  According to the invention described in claim 2, the front door is opened depending on whether or not the current azimuth angle of the front door detected by the azimuth detector differs from the reference azimuth angle stored in the reference azimuth angle storage means. Can be easily determined.

According to the third aspect of the invention, the difference between the reference azimuth angle stored in the reference azimuth angle storage means and the current azimuth angle of the front door detected by the azimuth detector is derived by the derivation means, and the derivation result Can reach the predetermined threshold value, it can be determined that the front door is in an open state, and in determining the open / closed state of the front door, the accuracy can be improved in consideration of errors that cannot be covered by the invention of claim 2. A high open / close state can be determined.

  At this time, by setting a threshold value in the derivation result of the derivation means as described above, it is possible to eliminate misperception due to the detection error of the azimuth detector itself and to operate the player according to the progress of the game (such as a stop button or It is possible to prevent misperception of vibration caused by chance buttons. In other words, some players who are enthusiastic about the game are enthusiastically struck when there is a person who operates the stop button with great effort to stop a specific symbol, or when there is an effect of repeatedly hitting the chance button. There are various players such as those who enter a special game such as a bonus game or the like, and who finish the game in a short time and beat the game machine with much stress to give vibration to the game machine. The gaming machine is firmly fixed to the island facility of the amusement store by nailing, but the front door and the housing itself vibrate due to the player's power, and the momentary shift of the front door due to the vibration is released. There is a risk of detection. Therefore, by providing a threshold as in the present claim, it is possible to prevent the player from erroneously determining that the front door has been opened even if the player is vibrated due to a gaming operation.

The main control device 5 is provided.

(Direction detector 31)
For example, an electronic compass can be used for the orientation detector 31. Such an azimuth detector (hereinafter also referred to as an electronic compass) 31 can handle the azimuth as an electrical signal. The azimuth detector (electronic compass) 31 detects “north” of geomagnetism by a magnetic sensor, ”As a reference azimuth, it is detected in which azimuth the object to which the azimuth detector (electronic compass) 31 is attached is directed. As shown in FIG. 4, if the object is oriented in the northeast direction, the object is oriented at 45 degrees from “north” to “east” which is the reference orientation, so the orientation of the object is “Northeast”. At this time, 45 degrees is the azimuth angle of the current object. By attaching such an electronic compass 31 to the upper right end (or lower right end) of the front door 3, the azimuth angle of the front door 3 that is opened and closed can be detected. The electronic compass 31 detects the azimuth angle at a certain period, and transmits a signal corresponding to the detected azimuth angle to the main control device 5.

(Reference azimuth storage means 52)
The reference azimuth storage means 52 stores, as a reference azimuth angle θa, the azimuth angle of the front door 3 that has been confirmed to be closed under a predetermined situation that is not illegal. The operation of the door key for locking / unlocking the front door locking device 24 possessed by a person in the position of managing the slot machine 1 such as a store clerk of the company is normally performed without being illegal. That is, a photo sensor is provided in the vicinity of the front door locking device 24 on the back side of the front door 3, and the optical path of the photo sensor is interrupted by a protrusion interlocked with the movement of the door key by rotating the door key in reverse (locking). With the interruption of the optical path of this photosensor, the azimuth angle transmitted from the electronic compass (azimuth detector) 31 is stored in the reference azimuth angle storage means 52 as the reference azimuth angle θa, and under normal conditions that are not illegal. In addition, the reference azimuth angle θa is set. In this embodiment, in order to simplify the description, it is assumed that the reference azimuth angle storage means 52 stores “reference azimuth angle θa = 90 degrees” as shown in FIG.

(Closed state setting judging means 53)
The closed state setting determination means 53 determines whether or not the closed state setting for storing the reference azimuth angle θa of the front door 3 in the closed state in the reference azimuth angle storage means 52 by the specific operation of the door key is performed. If it is determined that the closed state has not been set, a notification that the closed state is set by the effect lamp 9, the liquid crystal display 10, and the speakers 23L and 23R is made based on the determination result. . On the other hand, when it is determined that the closed state has been set, such notification is stopped.

(Opening / closing judgment means 54)
The open / close determining means 54 determines whether the front door 3 is opened or closed based on the current azimuth angle of the front door 3 detected by the electronic compass (azimuth detecting body) 31. As described above, the open / close determining means 54 calculates Means 54a are provided. The calculation means 54a includes a reference azimuth angle θa (hereinafter referred to as θa only when a mathematical expression is used) and a current azimuth angle θb (hereinafter, current azimuth angle θb) detected by the electronic compass 31. The difference Δθ is calculated only when the mathematical expression is used.

  When the difference Δθ calculated by the calculation unit 54a reaches a predetermined threshold value θt (hereinafter referred to as θt only when using mathematical formulas), the open / close determination unit 54 determines that the open state is detected and transmits an open signal. To do. This threshold value θt is within an allowable range in consideration of not detecting a slight error of the electronic compass 31, for example, vibration applied to the housing 2 by the player or movement when the front door 3 is strongly closed. Set to a numeric value.

<Description of operation>
The procedure for setting the closed state will be described with reference to the operation explanatory diagram of FIG. 5 and the flowchart of FIG.

  First, as shown in FIG. 7, when the power is turned on in S101, it is next determined whether or not the closed state is set by the closed state setting determining means 53, and the closed state is set in S102. If it is determined that the closed state is set, the closed state setting process is terminated. On the other hand, if it is determined that the closed state setting is not performed, the process proceeds to S103, and the effect lamp 9, the liquid crystal display 10, and the speakers 23L and 23R are notified to perform the closed state setting and the closed state is set. A setting request is made. At this time, lighting and blinking of the production lamp 9, a message display such as “Please set the door closed” on the liquid crystal display 10, and “Door setting” from the speakers 23L and 23R Please notify the user that the closed state is set by voice output or the like, and then proceed to the next S104.

  In S104, it is determined whether or not the closed state is set, that is, whether the door key is reversely rotated (specific operation). If the determination result indicates that the door key is not reversely rotated (specific operation), the determination in S104 is repeated. On the other hand, if it is a determination result that the door key is reversely rotated (specific operation), the process proceeds to the next S105, and the azimuth angle by the electronic compass 31 at that time is acquired as the reference azimuth angle θa and acquired in the next S106. The reference azimuth angle θa is stored in the reference azimuth angle storage means 52.

  More specifically, as shown in FIG. 5, the slot machine 1 enters the amusement store with the front door 3 closed so that the direction of the front door 3 detected by the electronic compass 31 becomes “east”. Assuming the case where it is installed, the current azimuth is “east” with respect to “north” which is the reference azimuth of geomagnetism, so the azimuth is 90 degrees, and a signal such as a voltage signal corresponding to 90 degrees Output from the electronic compass 31 to the main controller 5. At this time, by reversely rotating (locking) the door key, “90 degrees” is stored in the reference azimuth angle storage means 52 as the reference azimuth angle θa.

  In the next S107, the notification (closed state setting request) for prompting the closed state setting performed in S103 is stopped, and the closed state setting process ends.

  Such a closed state setting action may be performed when the slot machine 1 is installed in an amusement store, so it does not have to be performed every day and can be performed less frequently than the daily operation of the store clerk. Never become.

  Next, the opening / closing determination process will be described with reference to the operation explanatory diagram of FIG. 6 and the flowchart of FIG.

  First, as shown in FIG. 8, the current azimuth angle θb is acquired by the electronic compass 31 in S201, and in the next S202, the reference azimuth angle θa stored in the reference azimuth angle storage means 52 in S106 of FIG. The difference Δθ with respect to the current azimuth angle θb acquired in S201 is calculated by the calculation means 54a, and the process proceeds to the next S203, where the determination of whether the calculated difference Δθ is zero, that is, θb−θa = 0 is the open / close determination means 54 Is done.

  If the determination result in S203 is θb−θa = 0, that is, if the reference azimuth angle θa and the current azimuth angle θb match, it is determined that the front door 3 is not open, and S201. The process up to this point is repeated. On the other hand, if θb−θa = 0, that is, if the reference azimuth angle θa and the current azimuth angle θb are different, it is determined that the front door 3 is open, and the process proceeds to the next S204.

  Specifically, this is illustrated in FIG. The front door 3 when the reference azimuth angle θa is set is indicated by a dotted line, and the front door 3 when the current azimuth angle θb is acquired is indicated by a solid line. When the reference azimuth angle θa is “90 degrees”, when “southeast” is detected as the current azimuth by the electronic compass 31 when the front door 3 is opened, the current azimuth angle θb is “135 degrees”. The calculation means 54a calculates (135 degrees-90 degrees) as the difference Δθ (θb−θa) between the current azimuth angle θb (= 135 degrees) and the reference azimuth angle θa (= 90 degrees). . Here, since 135 degrees−90 degrees = 45 degrees, that is, θb−θa ≠ 0, the reference azimuth angle θa and the current azimuth angle θb do not match, and the front door 3 is in the open state. It is judged that there is. On the other hand, when “east” is detected as the current azimuth by the electronic compass 31, the current azimuth angle θb at that time is “90 degrees”, so the calculation unit 54 a causes the current azimuth angle θb (= 90 degrees). And the reference azimuth angle θa (= 90 degrees), a calculation of “90 degrees−90 degrees” is performed, resulting in a calculation result of θb−θa = 0, and the reference azimuth angle θa and the current azimuth angle θb Therefore, it is determined that the front door 3 is in the closed state.

  Then, in S204 shown in FIG. 8, in response to the determination result that the front door 3 in S203 is open, the effect lamp 9, the liquid crystal display 10, the speakers 23L, 23R, etc. are controlled, and the front door 3 Is notified that is open, and then the process proceeds to the next S205. Although it may be possible to set the closed state by mistake when the front door 3 is not locked, in that case, since the front door 3 is closed, the open state will be notified, As a result, the store clerk at the amusement store can recognize that the wrong closed state has been set.

  In S205, the current azimuth angle θb is acquired, and in the next S206, the difference between the reference azimuth angle θa stored in S106 of FIG. 7 and the current azimuth angle θb acquired in S205 is again calculated by the calculation means 54a. The calculation proceeds to S207, and it is determined whether θb−θa = 0.

  Here, in S201 to S203, it is determined whether or not to start notification that the front door 3 is open, but S205 to S207 determines whether or not to stop notification that the front door 3 is open. It is a process for.

  If the result of determination in S207 is not θb−θa = 0, that is, if the reference azimuth angle θa does not match the current azimuth angle θb, it is determined that the front door 3 is still open. Then, the process returns to S305, and the current azimuth angle θb is acquired again. On the other hand, if the determination result in S207 is θb−θa = 0, that is, if the reference azimuth angle θa and the current azimuth angle θb match, the front door 3 is not opened and is closed. The process proceeds to the next S208.

  In S208, the determination result that the front door 3 in S207 is not opened is received, and the notification that the front door 3 is opened in S204 is stopped. The azimuth angle θb is acquired, and the operations after S202 are repeated.

  As described above, in the slot machine of the first embodiment, by using the azimuth detector (electronic compass) 31, the reference azimuth angle θa differs from the current azimuth angle θb based on the azimuth using the geomagnetism. Since the opening / closing of the front door 3 is determined, the opening / closing of the front door 3 can be determined based on a simple calculation result. At this time, it is almost impossible to bend the geomagnetism illegally, and unlike conventional photosensors, it is less susceptible to detection interference by unauthorized jigs and can prevent fraud. it can.

[Second Embodiment]
Next, a slot machine which is a second embodiment of the gaming machine according to the invention will be described. Since the basic configuration of the slot machine of the present embodiment is the same as that of the first embodiment, differences from the first embodiment will be described.

In the first embodiment described above, the notification of the open state and the notification of the abnormal closed state setting are performed in the same manner in S204 of FIG. 8, but in the second embodiment, the notification of the open state and the abnormality are performed. The notification is made separately from the notification of the closed state setting.
The procedure of opening / closing determination of the present embodiment will be described in detail with reference to FIGS. 6A to 6C and the flowchart of FIG.

  In the second embodiment, the reference azimuth angle θa set in S106 of FIG. 7 is the origin (for example, 0 degree), and the angle calculated from the current azimuth angle θb of the front door 3 and the origin is Δθ. .

  In S301, the current azimuth angle θb is acquired. In the next S302, Δθ is calculated from the origin which is the reference azimuth angle θa and the current azimuth angle θb acquired in S301. In next step S303, in order to determine whether or not the closed state has been set correctly, it is determined whether or not Δθ calculated in S302 is within a range of 0 ≦ Δθ ≦ 100. Here, “100” means 100 degrees which is the opening range of the front door 3. Although the opening range is slightly different depending on the gaming machine, in this embodiment, the specific opening range is defined as “100” for easy understanding. The reason why 0 ≦ Δθ is set is 0 ≦ Δθ in order to detect such an abnormal situation because when Δθ becomes a negative numerical value, it is an abnormal situation such as an erroneous closed state setting. ing. In addition, it is not always necessary to satisfy 0 ≦ Δθ, and a slight negative value such as −1 ≦ Δθ may be appropriately determined in consideration of vibrations generated when the front door 3 is strongly closed.

  Specifically, as shown in FIG. 6A, when the origin which is the reference azimuth angle θa is “90 degrees” and the current azimuth angle θb of the front door 3 is “135 degrees”, Δθ is “45 degrees”. Therefore, since it is within the range of 0 ≦ Δθ ≦ 100, it is determined that the correct closed state is set, and the process proceeds to S304.

  Next, a case where an erroneous closed state setting is performed will be described. As shown in FIG. 6B, the closed state is set even though the front door 3 is open, and the origin, which is the reference azimuth angle θa, is set to “180 degrees”. When the azimuth angle θb is “90 degrees”, Δθ is “−90 degrees”. Therefore, since it is out of the range of “0 ≦ Δθ ≦ 100”, it is determined that an incorrect closed state is set, and the process proceeds to S310. Depending on the specifications of the electronic compass 31, Δθ may be detected as “270 degrees” as illustrated in FIG. 6C, but even in this case, it is outside the range of 0 ≦ Δθ ≦ 100. If it is determined that the wrong closed state has been set, the process proceeds to S310.

  In S304, it is determined whether or not Δθ (= 45 degrees) is greater than or equal to the threshold θt, that is, whether or not Δθ ≧ θt. As a result of this determination, if Δθ ≧ θt is not satisfied, that is, if Δθ has not reached the threshold value θt, it is determined that the front door 3 is not opened, and the process returns to S301, and the processing so far is repeated. On the other hand, if Δθ ≧ θt, that is, if Δθ has reached the threshold value θt, it is determined that the front door 3 is open, and the process proceeds to S305. In S305, the effect lamp 9, the liquid crystal display 10, The speakers 23L, 23R and the like are controlled to notify that the front door 3 is open, and then the process proceeds to S306. In S306, the current azimuth angle θb is acquired again, and in the next S307, Δθ is calculated from the origin that is the reference azimuth angle θa and the current azimuth angle θb acquired in S306, and in the next S308, the calculation is performed in S307. It is determined whether Δθ is 0 ≦ Δθ <θt. Here, in S301 to S304, it is determined whether or not the front door 3 has been correctly closed and whether or not to start the opening notification, but in S306 to S308, the front door 3 is open. This is a process for determining whether to stop the notification.

  If the determination result in S308 is not 0 ≦ Δθ <θt, it is determined that the front door 3 is still in the open state, the process returns to S306, and the current azimuth angle θb is acquired again. On the other hand, if the determination result in S308 is 0 ≦ Δθ <θt, it is determined that the front door 3 is not open and is closed, and the process proceeds to the next S309. In S309, the front door 3 in S308 is In response to the determination result that the door has not been opened, the opening notification of the front door 3 in S305 is stopped.

  By the way, in S310, in response to the determination result that the wrong closed state is set in S303, the production lamp 9, the liquid crystal display 10, the speakers 23L, 23R, and the like are controlled, and the closed state is set correctly. Announces that it is not broken. At this time, lighting and blinking of the production lamp 9, a message display such as “Please set the door closed” on the liquid crystal display 10, and “Door setting” from the speakers 23L and 23R Please notify the user of the closing state by voice output or the like, and then proceed to the next S311.

  In S311, it is determined whether the closed state is set, that is, whether the door key is reversely rotated. If the determination result indicates that the door key is not reversely rotated (specific operation), the determination in S311 is repeated. On the other hand, if it is a determination result that the door key is reversely rotated (specific operation), the process proceeds to the next S312 and the azimuth angle by the electronic compass 31 at that time is acquired as the reference azimuth angle θa, and the process proceeds to the next S306. The operations of S306 to S309 described above are performed.

  As described above, in the second embodiment, the reference azimuth angle θa is the origin, the angle calculated from the origin and the current azimuth angle θb of the current front door 3 is Δθ, and Δθ is 0 ≦ Δθ ≦. By determining whether or not the distance is within the range of 100, it is possible not only to determine whether the front door 3 is opened or closed, but also to determine whether or not the correct closed state has been set.

However, the present invention is not limited to this. It may be a condition that it cannot be done.

  Further, in the first embodiment and the second embodiment, the case where the closed state setting (memory of the reference azimuth angle) is performed when the slot machine is installed in the game shop has been described. Instead, the closed state may be set every time the power is turned on at the start of business or every other time the power is turned on.
