The opening / closing body is detected to be opened based on a change in charge amount of the first power storage means and the second power storage means.

According to the present invention, even when the opening / closing body is opened / closed in a state where the power supply to the gaming machine is cut off, it can be found that the opening / closing has occurred.

First, the invention that can be extracted from the present embodiment will be described while showing effects and the like as necessary.

The following means are as follows: “A pachinko machine, which is a kind of gaming machine, includes a main body frame that can be opened and closed with respect to an outer frame, and a front door that can be opened and closed with respect to the main body frame. The pachinko machine is provided with a control device and an opening switch for detecting opening of the main body frame with respect to the outer frame and opening of the front door with respect to the main body frame. Are opened by the opening switch, and the detection result is input to the control device, which opens the front door and the body frame based on the detection result from the opening switch. If it is determined that the alarm has occurred, a notification to that effect is executed using the speaker unit or the lamp unit, etc. Here, in the pachinko machine, the front door is opened and the game area provided on the front side of the main body frame is Fraud In addition, it is also assumed that the main body frame is opened and the control device mounted on the back side of the main body frame is fraudulent. In this situation, as described above, the opening of the front door and the main body frame is grasped by the control device, and notification processing etc. is executed for it. However, in game halls, the pachinko machine is usually turned off after the store is closed in order to suppress the deterioration of gaming parts, etc. caused by the continuous energization of the pachinko machine and to realize energy saving. After the power of the pachinko machine is cut off, the power supply to the control device is stopped and the control device cannot grasp that the front door or the main body frame has been opened and closed. Information office Therefore, it has been difficult for conventional pachinko machines to cope with the above fraudulent acts while the power is cut off.The above problem does not occur only with pachinko machines, This may occur in other gaming machines having an opening / closing body such as a main body frame, for example, slot machines, parrots, etc. " in order to solve the technical background and problems.

Means 1. An opening / closing body (game machine main part 12 or front door frame 14) supported to be openable / closable with respect to a support target (outer frame 11 or main body frame 13);
An electric device (main control device 162, payout control device 242 and the like) that is provided on the back side or rear of the opening / closing body and operates based on electric power supplied from an external power source;
Closure detection means (first monitoring device 250, second monitoring device 290, etc.) for detecting that the opening / closing body is closed when the opening / closing body is closed at least,
When the closing detection means detects that the opening / closing body has been closed in a state where the opening / closing body is provided on the rear side or rear of the opening / closing body and at least the power supply from the external power supply is stopped. A gaming machine comprising storage means for storing the detection result (for example, the first counter circuit 320 or the second counter circuit 330 of the main controller 162).

  In the gaming machine of means 1, the fact that the opening / closing body is closed can be detected by the closing detection means when the opening / closing body is closed at least with respect to the support target. That is, by detecting the fact that it has been closed, it is possible to grasp the fact that the opening / closing body has been opened indirectly. At least in the state where the supply of power from the external power supply is stopped, the detection result of the detection means, that is, the closing fact of the opening / closing body is stored in the storage means. The fact that the opening / closing body was opened and closed in the state where the supply of electric power is stopped by checking the detection result stored in this way, for example, when the supply of electric power is started (the fact that it is at least closed) ).

  Especially in this means, when the opening / closing body is closed, the opening / closing fact is memorized. For this reason, the memory | storage of an opening / closing fact can be preserve | saved suitably. Assuming that the opening / closing fact is memorized only when the opening / closing body is opened, the opening / closing body can be opened in the state of being stored. When the opening / closing body is opened as described above, access to the inside of the gaming machine (specifically, the storage means) is facilitated. That is, it is assumed that fraud to the storage means and the like is also facilitated in a state in which fraud is easily performed on an electrical device or the like provided on the back side or rear of the opening / closing body. In such a case, there is a possibility that the storage means or the like is accessed and the storage of the closing detection is improperly tampered. If such alteration of memory is performed, there is a possibility that the opening / closing fact of the opening / closing body may be concealed.

  In this regard, when the opening / closing body is closed as described above, the opening / closing fact (specifically, the closing fact) is memorized. Access to the means and the like can be prevented. Therefore, it is possible to prevent the inconvenience that the opening / closing fact of the opening / closing body is concealed by altering the memory stored by the storage means. As a result, it is possible to suitably detect the closing of the opening / closing body in a state where the power supply is stopped, and it is possible to contribute to the improvement of crime prevention. For example, the closing detection may be performed when the opening / closing body is set in advance and reaches the closed position.

  The “detection result” indicates a state (for example, information) in which the closing fact of the opening / closing body detected by the closing detection unit can be stored in the storage unit. For example, in addition to including information such as a signal output from the closing detection means, if the information is changed or converted to a different information form before being stored in the storage means, the information form after the change or conversion is changed. Is included.

Mean 2. Limiting means (for example, a locking device) that restricts movement of the opening / closing body in the opening direction when the opening / closing body is located within a predetermined range including a closed position with respect to the support target in the entire movable range of the opening / closing body. 170 collar 189 and collar bracket 190),
2. The gaming machine according to claim 1, wherein the closing detection means detects the closing in a state where the movement of the opening / closing body in the opening direction is restricted by the restriction means.

  According to the means 2, when the opening / closing body is located in a predetermined range in the entire movable range of the opening / closing body, the opening / closing body is restricted by the restricting means. In such a state, detection by the detection means is performed, and the opening / closing fact (specifically, the closing fact) is stored by the storage means. Since the opening / closing of the opening / closing body is restricted in the state in which the opening / closing fact is stored in this way, the opening / closing body is opened to the extent that re-detection is not performed after the closing is detected, and unauthorized access to the storage means or the like is made. Such inconveniences can be suitably suppressed.

  In addition, when the opening / closing body is moved outside the predetermined range and the stored data has been tampered with, the opening / closing body is again moved into the predetermined range and the release thereof is restricted. The opening / closing fact will be memorized. Thereby, the concealment act of the opening and closing fact can be made difficult, and it can contribute to the improvement of crime prevention.

  “Restricting movement in the opening direction” indicates that the movement of the opening / closing body in the opening direction within the predetermined range is completely suppressed, and the opening operation within the predetermined range is permitted. This includes suppressing movement (opening operation) to a position out of the range.

  Means 3. When the opening / closing body is located in the predetermined range, a restriction portion is provided that restricts access to the back side and the rear side of the opening / closing body via a boundary portion between the support target and the opening / closing body. A gaming machine according to means 2, characterized by:

  According to the means 3, when the opening / closing body is located within the predetermined range, access to the back side and the rear side of the opening / closing body is restricted. Thereby, in the state where the detection result is stored in the storage unit, it is possible to suitably avoid the occurrence of inconvenience such as unauthorized access to the storage unit. For example, as the restricting portion, at least one of the opening / closing body and the support target may be provided with a shielding portion that covers a boundary portion with the other. Specifically, when the opening / closing body is provided so as to be rotatable with respect to the support target, the shielding portion (the outer periphery of the outer frame 11) covers at least the outer peripheral edge of the opening front side of the opening / closing body from the side of the gaming machine. A surface) may be provided, and the overlap between the shielding portion and the opening / closing body may be maintained within the predetermined range. Thereby, in a state where the opening / closing body is within a predetermined range, access to the storage means and the like from the outside of the gaming machine is blocked by the shielding unit, and alteration of the detection result can be suitably avoided.

  Means 4. A locking device that locks the opening / closing body in a closed state with respect to the support object, and the closure detecting means is moved when the opening / closing body and the support object are shifted to a locked state by the locking device. The gaming machine according to the means 1, wherein the closing is detected by.

  A practically preferable configuration can be realized by using a configuration that is normally provided in a gaming machine called an opening / closing body locking device. Specifically, when the opening / closing body and the support target are shifted to the locked state by the locking device, the closing is detected, and the detection result is stored in the storage means. Thus, in the state where the detection result is stored, since the opening / closing body is shifted to the locked state, it is difficult to access the storage means. Therefore, it is possible to suitably suppress the occurrence of inconvenience that the detection result is falsified. For example, the locking device includes a first locking portion provided on one of the opening / closing body and the support target and a second locking portion provided on the other, and the both locking portions are in an unlocked state. It is preferable that the closure is detected by the closure detection means when shifting from the locked state to the locked state.

  Means 5. The storage means is provided in at least one of the power storage means capable of accumulating the supplied charge and releasing the stored charge, the opening / closing body and the support target, and based on at least the closing operation of the opening / closing body, The gaming machine according to any one of means 1 to means 4, comprising charge amount varying means for changing the charge amount of the power storage means.

  According to the means 5, the charge amount of the power storage means changes based on at least the closing operation of the opening / closing body. Specifically, when the open / close body is opened in a state where the power supply is interrupted at night or the like, a difference occurs in the charge amount of the power storage means before and after the open / close body is opened / closed. Specifically, the charge amount of the power storage means increases or decreases. That is, the fact that the open / close body is opened and closed while the power supply is shut off (at least the fact that it is closed) can be stored as a change in the charge amount. Based on the change in the charge amount, it is possible to discover the opening / closing fact of the opening / closing body. Therefore, it is possible to improve crime prevention while avoiding continuous power supply at night or the like, that is, while contributing to energy saving (energy saving).

Means 6. The power storage means stores charges in a state where power is supplied from the external power source,
6. The gaming machine according to claim 5, wherein the variable charge amount reduces the charge amount of the power storage means based on the operation of the opening / closing body in a state where power supply from the external power source is cut off. .

  According to the means 6, the power storage means stores electric charges in a state where electric power is supplied from an external power source, and reduces the electric charges stored based on the operation of the opening / closing body in a state where electric power supply is cut off. It is done. That is, it is possible to realize a change in the amount of charge in a state where the power supply is interrupted by using (specifically, releasing) the charge stored in itself during the power supply. For this reason, it is not necessary to increase the amount of charge by additional supply of power or the like, and it is possible to suitably realize a change in the amount of charge of the power storage means in a state where the power supply is interrupted.

  In addition, if it is configured to detect closing of the opening / closing body by increasing the amount of charge of the power storage means, the charge of the power storage means may decrease due to natural discharge or the like, which may make it difficult to detect the closure. There is. Specifically, if the amount of charge is reduced based on the operation of the opening / closing body and then the amount of charge decreases to the same state as before storage due to natural discharge, etc., there is a possibility that the amount of charge has not been changed. There is. In such a case, there is a possibility that the closing fact may not be grasped even though the opening / closing body is closed. On the other hand, as shown in this means, when it is configured to detect the closing of the opening and closing body by a decrease in the charge amount of the power storage means, even if the charge amount is reduced to a predetermined amount or less due to natural discharge or the like, A difference will occur between the original charge amount. For this reason, it is possible to easily grasp the change in the charge amount. In such a case, it is difficult to identify whether the cause of the change in the charge amount is due to the opening / closing of the opening / closing body, but at least the opening / closing body may have been opened, It can be inspired. Thereby, even if it is a case where fraud is performed with respect to a game machine by opening and closing an opening-closing body, the inconvenience that such fraud is overlooked can be suppressed.

  In general, when determining the change in the charge amount, the initial charge amount at the time of power interruption is compared with the final charge amount at power-on, or the final charge amount is compared with a predetermined threshold value. It is thought that. In addition, it is assumed that the information on the amount of charge is sent to a determination device (for example, main controller 162) through a signal line or the like. In such a case, when the supply of information is interrupted by cutting the signal lines or the like, the amount of power stored in the determination device can be determined to be zero. As described above, if the configuration is such that the closing is stored by reducing the charge amount, even if the information supply is interrupted, it can be understood that the closing has been performed. That is, when it is determined that the charge amount is 0, it is considered that the charge amount has decreased at least below the terminal charge amount or the threshold value, and it is possible to suggest that the opening / closing may be performed illegally. . From the above, it can contribute more favorably to the improvement of crime prevention by performing the closure detection based on the decrease in the charge amount than performing the closure detection based on the increase in the charge amount of the power storage means. it is conceivable that.

Means 7. An opening / closing body (game machine main part 12 or front door frame 14) supported to be openable / closable with respect to a support target (outer frame 11 or main body frame 13);
An electric device (main control device 162, payout control device 242 and the like) that is provided on the back side or rear of the opening / closing body and operates based on electric power supplied from an external power source;
Closure detection means (first monitoring device 250, second monitoring device 290, etc.) for detecting that the opening / closing body is closed when the opening / closing body is closed at least,
When the closing detection means detects that the opening / closing body has been closed in a state where the opening / closing body is provided on the rear side or rear of the opening / closing body and at least the power supply from the external power supply is stopped. Storage means for storing the closing fact (for example, the first counter circuit 320 and the second counter circuit 330 of the main controller 162),
When the opening / closing body is open with respect to the support object, the rear side and the rear side of the opening / closing body are exposed, and when the opening / closing body is closed with respect to the support object, A gaming machine characterized in that exposure of the rear side and the rear side of the opening / closing body is suppressed.

  According to the means 7, when the opening / closing body is opened, the back side and the rear side of the opening / closing body are exposed. In such a state, the storage means provided on the back side or the rear side of the opening / closing body can be confirmed. Since the storage means can be confirmed by opening the opening / closing body in this way, it is easy to ensure workability when performing inspections such as maintenance and fraud. That is, it is possible to suitably realize a configuration that achieves the same effects as the means 1 while suitably avoiding the occurrence of inconvenience such as deterioration of maintainability.

  Note that the “exposed state” means that the opening / closing body is opened and the back side of the opening / closing body is exposed in front of the gaming machine, and that the opening side of the gaming machine is opened to the gaming machine. The state which became visible from the front of is shown. More specifically, a state in which the opening / closing body is opened for the person on the front side of the gaming machine to access the back side of the opening / closing body and the rear of the opening / closing body is shown.

Means 8. A first opening / closing body (main body frame 13 of the gaming machine main part 12) that is supported directly or indirectly with respect to the support target (outer frame 11) and that can be opened and closed;
A game area (a front portion of the game board 81) provided on the front side of the first opening / closing body, and from which a game ball flows down;
A second opening / closing body (of the game machine main part 12) that is supported directly or indirectly with respect to the support target and is provided so as to be able to open and close the front side of the first opening / closing body and covers at least the gaming area. Front door frame 14),
A first closing detection means (such as a first monitoring device 250) for detecting that the first opening / closing body has been closed when the first opening / closing body is closed;
Second closing detection means (second monitoring device 290 etc.) for detecting that the second opening / closing body has been closed;
An electrical device (main control device 162, payout control device 242 and the like) that is provided on the back side or rear of the first opening / closing body and operates based on electric power supplied from an external power source;
Provided on the back side or the rear side of the first opening / closing body, and at least one of the opening / closing bodies is detected by the both closing detection means in a state where power supply from the external power source is stopped at least. Storage means (for example, the first counter circuit 320 or the second counter circuit 330 of the main control device 162) for storing the opening / closing fact in the case of
When the first opening / closing body is open, the back side and the rear side of the first opening / closing body are exposed, and when the first opening / closing body is closed, the back side of the first opening / closing body. And a gaming machine characterized in that exposure to the rear is suppressed.

  According to the means 8, the fact that the first opening / closing body is closed can be detected by the first closing detection means when the first opening / closing body is at least closed with respect to the support target. At least in the state where the supply of electric power from the external power supply is stopped, the detection result in the first closing detection means, that is, the opening / closing fact of the first opening / closing body is stored in the storage means. The fact that the first opening / closing body was opened / closed in a state where the supply of electric power is stopped (at least closed) by checking the detection result stored in this way, for example, when the supply of electric power is started That fact).

  In this means, in particular, when the first opening / closing body is closed, the opening / closing fact is stored. For this reason, the memory | storage of an opening / closing fact can be preserve | saved suitably. Assuming that the opening / closing fact is memorized only when the first opening / closing body is opened, the first opening / closing body can be opened in the stored state. Thus, in a state where the first opening / closing body is opened, access to the inside of the gaming machine (specifically, the storage means) is facilitated. That is, it is assumed that fraud with respect to the storage means and the like is also facilitated in a state where fraud is easily performed on the electrical equipment or the like provided on the back side or the rear of the first opening / closing body. In such a case, there is a possibility that the storage means or the like is accessed and the storage of the closing detection is improperly tampered. If such memory alteration is performed, there is a possibility that the opening / closing fact of the first opening / closing body may be concealed.

  In this regard, if the first opening / closing body is memorized when the first opening / closing body is closed as described above, the first opening / closing body itself is in a closed state, so that the first opening / closing body itself stores the storage means, etc. It becomes possible to prevent access to. Therefore, it is possible to prevent the inconvenience that the opening / closing fact of the first opening / closing body is concealed by falsifying the storage stored by the storage means. As a result, the closing detection of the first opening / closing body in a state where the power supply is stopped can be suitably performed, which can contribute to the improvement of crime prevention.

  In addition to the effects described above, the following excellent effects can be obtained. In a gaming machine having a gaming area where a game ball flows down, not only the inside of the gaming machine (specifically, a control device or the like) but also the gaming area itself is likely to be illegal. If the second opening / closing body is opened and fraud is performed on the game area, the opening / closing of the second opening / closing body may be detected by the second closing detection means, and there is a possibility that the fraud has been performed. I can understand that there is. In addition, when the second opening / closing body is opened in this way, the storage means is provided behind or behind the first opening / closing body, so that access to the storage means is blocked by the first opening / closing body. It is done. On the other hand, in a state where the first opening / closing body is open to the support target, the back side and the rear side of the first opening / closing body are exposed. In such a state, it is possible to access the storage means provided on the back side or the rear side of the first opening / closing body. As described above, if the first opening / closing body is opened and the detection record in the storage means is falsified, it is difficult to grasp the fact of opening / closing of the second opening / closing body. However, in this means, the closing of the first opening / closing body is detected as described above, and the fact of opening / closing of the first opening / closing body can be grasped by closing the first opening / closing body with respect to the support target. It is possible. That is, by storing and storing the closing detection result of the first opening / closing body, it is possible to grasp at least the fact that the first opening / closing body is opened / closed (the fact that it is at least closed). And when grasping | ascertaining the opening / closing fact of such a 1st opening / closing body, it can be suggested that the 2nd opening / closing body may have been opened and closed collectively. Thereby, even if it has the structure which has several opening-and-closing bodies, concealment of an opening-and-closing fact can be made difficult, and it can contribute to the improvement of crime prevention.

  Note that “supported directly or indirectly with respect to the support target” indicates that it is supported by the support target or is supported via another configuration with respect to the support target. For example, in the case of the second opening / closing body, it may be directly supported by the support object, or when the first opening / closing body is supported by the support object, it may be supported by the first opening / closing body.

  In addition, the “exposed state” means that the first opening / closing body is opened and the back side of the first opening / closing body is exposed in front of the gaming machine, and the game is performed by opening the first opening / closing body. The state where the back side of the machine is visible from the front of the gaming machine is shown. More specifically, a state in which the first opening / closing body is opened for the person on the front side of the gaming machine to access the back side of the first opening / closing body and the rear of the first opening / closing body is shown.

  The technical ideas that can be extracted within the scope of disclosure of the present specification are described below.

(A1). An opening / closing body (game machine main part 12 or front door frame 14) supported to be openable / closable with respect to a support target (outer frame 11 or main body frame 13);
An electric device (main control device 162, payout control device 242 and the like) that is provided on the back side or rear of the opening / closing body and operates based on electric power supplied from an external power source;
A movable portion (a metal fitting 185) that is displaced based on an opening / closing operation of the opening / closing body;
Electromotive force generating means (monitoring devices 250, 290) for generating an electromotive force by displacement of the movable part;
An gaming machine comprising opening / closing detection means (counter circuits 320, 330, etc.) for detecting opening / closing of the opening / closing body based on the electromotive force of the electromotive force generation means.

  In the gaming machine of A1, the movable part is displaced based on the opening / closing operation of the opening / closing body. An electromotive force is generated by the electromotive force generating means due to the displacement of the movable part, and the opening / closing detection of the opening / closing body is performed by the opening / closing body detection device. Thus, in the electromotive force generating means, an electromotive force is generated by the displacement of the movable part without requiring the supply of power from the external power source. For this reason, the fact that the opening / closing body is opened and closed can be grasped by the electromotive force even when power is not supplied to the gaming machine outside the business hours of the game hall. Specifically, opening / closing detection of the opening / closing body can be realized based on the generated electromotive force. Even if the opening / closing body is opened at the time of power interruption and unauthorized access to an electrical device or the like is performed, it is possible to grasp the fact that such unauthorized operation has been performed. Therefore, it is possible to improve crime prevention while avoiding continuous power supply at night or the like, that is, while contributing to energy saving (energy saving).

  The “electromotive force generating means” means means for converting the kinetic energy of the movable part into electric energy. Incidentally, the electromotive force of the electromotive force generating means may be used as a signal, or may be used as the driving power of the open / close detecting means.

  Further, the “opening / closing detection means” may be configured to store the fact of the opening / closing detection of the opening / closing body while the power supply is cut off. In such a case, the open / close detection means can also be referred to as open / close storage means.

(A2). The electromotive force generating means is
A conductor (coil 271, 295) that conducts electricity while producing a potential difference by changing the magnetic flux,
A magnetic body (magnetic bodies 261 and 293) that changes the magnetic flux,
The gaming machine according to A1, wherein the relative position of the magnetic body and the moving body is displaced in accordance with the displacement of the movable portion.

  In order to generate an electromotive force by the displacement of the movable part, it is preferable that a potential difference is generated in the conductor due to the displacement of the relative position between the magnetic body and the conductor as shown in A2. An electromotive force can be generated by electromagnetic induction because the relative position of the magnetic body and the conductor is displaced in accordance with the displacement of the movable portion. Thus, by generating an electromotive force using electromagnetic induction, it is possible to generate an electromotive force even during power interruption.

  Note that the magnetic body and the movable portion are not necessarily separate bodies, and both may be integrated. In such a case, the magnetic body can also be referred to as a movable part, and the movable part can also be referred to as a magnetic body. It is also possible to use the conductor and the movable part in an integrated manner.

(A3). A drive mechanism for displacing the movable part in a predetermined direction based on an opening / closing operation of the opening / closing body;
The drive mechanism generates power different from the power of the opening / closing body itself generated by the opening / closing operation of the opening / closing body,
The gaming machine according to A2, wherein an electromotive force is generated in the electromotive force generating means based on the displacement of the movable portion in the predetermined direction.

  According to (A3), the movable portion moves in a predetermined direction based on the opening / closing operation of the opening / closing body. In such a case, the movable part is displaced by the power generated by the drive mechanism. Since power is supplied using a power source (driving mechanism) other than the opening / closing operation of the opening / closing body, it is easy to ensure a desired displacement speed of the movable part regardless of the opening / closing speed of the opening / closing body.

  The generated electromotive force changes according to the displacement speed of the relative position between the magnetic body and the conductor. In such a case, if the displacement speed of the relative position between the magnetic body and the conductor is reduced, it may be difficult to ensure a sufficient electromotive force. For example, when the displacement of the relative position between the opening and closing body and the support object is directly used for the displacement of the relative position between the magnetic body and the conductor, the relative speed of the magnetic body and the conductor depends on the opening and closing speed of the opening and closing body. Become. For this reason, when the opening and closing body is opened and closed slowly, there is a problem that a sufficient change in magnetic field cannot be obtained and generation of electromotive force can be suppressed. Thus, if generation | occurrence | production of an electromotive force is suppressed, it will estimate | forecast that the opening / closing detection of an opening / closing body by an opening / closing detection means will become difficult. However, in A3, the displacement speed of the movable part is determined depending on the power generated by the drive mechanism. That is, the displacement speed of the relative position between the magnetic body and the conductor depends on the power of the operating mechanism. Without depending on the opening / closing speed of the opening / closing body, the displacement speed of the relative position between the magnetic body and the conductor is secured by the operation mechanism, and an electromotive force having a desired magnitude is easily generated. More specifically, the inconvenience that the desired electromotive force cannot be obtained due to variations in the opening / closing speed of the opening / closing body is avoided. Therefore, the certainty of opening / closing detection can be increased and it can contribute to further improvement of crime prevention.

  (A4). The movable part is set to be movable from the first position to the second position, and an electromotive force is generated in the electromotive force generating means based on the movement of the movable part from the first position to the second position. The game machine according to A3, wherein the drive mechanism includes urging means (coil springs 192 and 193) for urging the movable portion toward the second position.

  According to A4, an electromotive force is generated when the movable portion moves from the first position to the second position. The movable part is biased to the second position by the biasing means, and is actively moved to the second position by the biasing force of the biasing means.

(A5). In a state where the movable portion is in a predetermined range of the entire opening / closing range of the opening / closing body, the movable portion is moved to the first position against the biasing force of the biasing means in accordance with the opening / closing operation of the opening / closing body. Provided with guide portions (guide inclined portions 65a, 189b),
The game machine according to A4, wherein after the movement of the movable part by the guide part is finished, the movable part is moved from the first position to the second position.

  According to A5, the movable part is moved to the first position by the guide part in accordance with the opening / closing operation of the opening / closing body. The movable part is moved to the second position by the urging force of the urging means after reaching the first position, that is, after the movement by the guide part is completed. In A5, in particular, preparation for generating an electromotive force can be performed by moving the movable portion to the first position using the opening / closing operation of the opening / closing body. A practically preferable configuration can be realized by enabling a preliminary operation for generating an electromotive force by the guide portion.

(A6). A support target (outer frame 11 or main body frame 13);
An opening / closing body (game machine main part 12 or front door frame 14) supported to be openable and closable with respect to the support object;
An electric device (main control device 162, payout control device 242 and the like) that is provided on the back side or rear of the opening / closing body and operates based on electric power supplied from an external power source;
A locking device that locks the opening / closing body with respect to the support object when the opening / closing body is closed;
As the magnetic flux changes, a potential difference is generated, and a conductor (coils 271 and 295) that conducts electricity and a magnetic body (magnetic bodies 261 and 293) that changes the magnetic flux are provided. Electromotive force generating means (monitoring devices 250, 290) for generating an electromotive force when the relative positions of the magnetic body and the conductor are displaced,
An gaming machine comprising opening / closing detection means (counter circuits 320, 330, etc.) for detecting opening / closing of the opening / closing body based on the electromotive force of the electromotive force generation means.

  In the A6 gaming machine, the locking device operates when the opening / closing body is closed, and the opening / closing body and the support target are locked. With the operation of the locking device, the relative position between the magnetic body and the conductor is displaced, and an electromotive force is generated by electromagnetic induction. Based on this electromotive force, opening / closing of the opening / closing body is detected.

  In A6, as described above, the relative position between the magnetic body and the conductor is displaced with the operation of the locking device. That is, the relative position of the magnetic body and the conductor is displaced depending on an operation different from the operation of the opening / closing body in the closing direction. Thereby, it is easy to ensure the desired displacement speed of the relative position between the magnetic body and the conductor, regardless of the moving speed of the opening / closing body in the closing direction.

  Thus, if the displacement of the relative position of the magnetic body and the conductor is realized by utilizing the operation of the locking device assumed to be normally provided in the gaming machine, it is unnecessary to add a mechanism or the like for displacing the relative position. Become. That is, by adding a function for operating the electromotive force generating means to the locking device, it is possible to suppress complication of the configuration that may occur due to the introduction of the opening / closing detection function.

(A7). The locking device is
A fixing latch (a saddle fitting 63 or a saddle fitting 190) fixed to either the support object or the opening / closing body;
The opening / closing body is mounted on the other in a state where it can move between two different positions of a locking position and a locking release position with respect to the fixed locking tool, and locked with the fixed locking tool. A movable locking tool (a hook receiving member 180 and a hook metal 185) that locks the supporting object;
Biasing means (coil springs 192, 193) for biasing the movable latch toward the side latched with the fixed latch;
The gaming machine according to A6, wherein a relative position of the magnetic body and the conductor is displaced with the movement of the movable locking tool between the locking position and the locking release position. .

  According to A7, the movable locking tool is biased from the locking release position toward the locking position. Depending on this biasing force, the movable locking tool moves toward the fixed locking tool. Thus, by making the movement of the movable locking tool depend on the biasing force of the biasing means, the displacement speed of the movable locking tool can be set independently and independently without depending on the opening / closing speed of the opening / closing body. Thereby, the displacement speed of the relative position of a magnetic body and a conductor is ensured, and it becomes easy to ensure generation | occurrence | production of the electromotive force of a desired magnitude | size. More specifically, the inconvenience that the desired electromotive force is not generated due to variation in the opening / closing speed of the opening / closing body is suppressed.

  In addition, since the movable locking tool and the fixed locking tool are locked in a biased state, the locked state of both is difficult to be released. For this reason, the inconvenience that the locked state is released due to external vibration or the like is suppressed. That is, the inconvenience that the movable locking tool moves to the locking release position due to external vibration or the like is suppressed. By suppressing the movement of the movable locking tool in the state where the opening / closing body is closed in this manner, the generation of electromotive force due to the movement of the movable locking tool unexpectedly or the like can be suppressed. Therefore, it is possible to suppress erroneous detection of the open / close detection means and improve the open / close detection accuracy.

(A8). The support target has at least a shielding part (an outer peripheral surface of the outer frame 11) that covers an outer peripheral edge of the opening / closing body from the outside.
The gaming machine according to A7, wherein a trajectory when the movable locking tool moves between the two positions is set inward of the shielding portion.

  According to A8, when an electromotive force is generated, access from the outside of the gaming machine to the movable locking device is blocked by the shielding portion. Thereby, the shift to the locked state, that is, the movement of the movable part locking tool is protected, and the generation of the desired electromotive force is ensured. For example, by inserting an improper tool such as a wire on the track of the movable locking tool to prevent the movement of the movable locking tool, the displacement speed of the relative position between the magnetic body and the conductor can be suppressed, and the generated electromotive force can be reduced. Inconveniences such as being suppressed to be smaller than a predetermined size can be suppressed. That is, it is possible to ensure the opening / closing detection function.

  (A9). The gaming machine according to any one of A1 to A8, wherein the electromotive force generating means generates an electromotive force at least when the opening / closing body is closed.

  According to A9, an electromotive force is generated at least when the opening / closing body is closed, and opening / closing detection by the opening / closing detection means is performed based on the electromotive force. If the configuration is such that an electromotive force is generated and the opening / closing detection is performed when the opening / closing body is opened, the opening / closing body is opened in the state where the opening / closing detection is performed, and the inside of the gaming machine (for example, an opening / closing detection means) Access to can be possible. When the opening / closing body is opened by a fraudulent person, the opening / closing detection means or the like is accessed, and there is a possibility that the opening / closing detection state is canceled or the opening / closing detection history is deleted. However, by opening / closing detection when the opening / closing body is closed as described above, the opening / closing body is closed when the opening / closing is detected, and the opening / closing body itself suppresses access to the opening / closing detection means and the like. Is possible. Thereby, it becomes possible to suppress the inconvenience that the opening / closing fact of the opening / closing body is concealed. Therefore, further improvement in crime prevention can be expected.

  (A10). Provided with notification means (error display lamp section 24, speaker section 26, symbol display apparatus 91, etc.) that is connected to the external power source and notifies the occurrence or possibility of predetermined fraud based on the detection result of the detection means. The gaming machine according to any one of A1 to A9, characterized in that:

  According to A10, by providing the notification means in the gaming machine, detection of unauthorized opening / closing of the opening / closing body and the notification thereof can be completed by the gaming machine. Thereby, it is possible to promote the introduction of a gaming machine having a fraud countermeasure function regardless of the business form of the hall. For example, in a configuration in which a gaming machine has a picture display device (picture display device 91), a lamp unit (error display lamp unit 24), a speaker (speaker unit 26), and the like, if these picture display devices are used as notification means. Good.

(B1). An opening / closing body (game machine main part 12 or front door frame 14) supported to be openable / closable with respect to a support target (outer frame 11 or main body frame 13);
An electric device (main control device 162, payout control device 242 and the like) that is provided on the back side or rear of the opening / closing body and operates based on electric power supplied from an external power source;
Power storage means (source capacitors 353, 363, etc.) capable of accumulating the supplied charge and releasing the stored charge;
Based on at least one of an opening operation and a closing operation of the opening / closing body provided in at least one of the opening / closing body and the support target and in which power supply from the external power source is interrupted, A gaming machine comprising charge amount varying means (monitoring devices 250, 290, MOSFETs 354, 364, etc.) for changing the charge amount.

  In the gaming machine of B1, the charge amount of the power storage means changes based on at least one of the opening and closing operations of the opening / closing body. Specifically, when the open / close body is opened and closed in a state where the power supply is interrupted at night or the like, a difference occurs in the charge amount of the power storage means before and after the open / close body is opened and closed. Specifically, the charge amount of the power storage means increases or decreases. That is, the fact that the open / close body is opened and closed while the power supply is shut off can be stored as a change in the amount of charge. It is possible to discover the opening / closing fact of the opening / closing body based on the change in the charge amount. Therefore, it is possible to improve crime prevention while avoiding continuous power supply at night or the like, that is, while contributing to energy saving (energy saving).

(B2). The power storage means stores electric charges in a state where electric power is supplied from the external power source,
The gaming machine according to B1, wherein the charge amount varying means reduces the charge amount of the power storage means based on an operation of the opening / closing body in a state where power supply from the external power supply is cut off. .

  According to B2, the electric storage means stores electric charges in a state where electric power from an external power source is supplied, and in the state where electric power supply is cut off, the electric charge stored based on the operation of the opening / closing body decreases. To do. In other words, by using the charge stored in itself during power supply (specifically by releasing it), in order to realize a change in the amount of charge in a state where the power supply is interrupted, There is no need to increase the amount of charge. For this reason, it is possible to suitably realize a change in the amount of charge of the power storage means in a state where the power supply is interrupted.

  In addition, if the configuration is such that the opening / closing of the opening / closing body is detected by increasing the amount of charge of the power storage means, the charge of the power storage means may be reduced due to natural discharge or the like, which may make it difficult to detect the opening / closing. There is. Specifically, if the amount of charge is reduced based on the operation of the opening / closing body and then the amount of charge decreases to the same state as before storage due to natural discharge, etc., there is a possibility that the amount of charge has not been changed. There is. In such a case, there is a possibility that the fact of opening / closing cannot be grasped even when the opening / closing body is opened / closed. On the other hand, as shown in B2, when the opening / closing body is detected to be opened / closed by the decrease in the charge amount of the power storage means, even if the charge amount is reduced to a predetermined amount or less due to natural discharge or the like, A difference will occur between the charge amount and the charge amount. For this reason, it is possible to easily grasp the change in the charge amount. In such a case, it is difficult to identify whether the cause of the change in the charge amount is due to the opening / closing of the opening / closing body, but at least suggests that the opening / closing body may have been opened / closed, It can be inspired. Thereby, even if it is a case where fraud is performed with respect to a game machine by opening and closing an opening-closing body, the problem that this is overlooked can be suppressed.

  In general, when determining the change in the charge amount, the initial charge amount at the time of power interruption is compared with the final charge amount at power-on, or the final charge amount is compared with a predetermined threshold value. It is thought that. In addition, it is assumed that the information on the amount of charge is sent to a determination device (for example, main controller 162) through a signal line or the like. In such a case, when the supply of information is interrupted by cutting the signal lines or the like, the amount of power stored in the determination device can be determined to be zero. As described above, if the configuration is such that the unauthorized opening / closing is stored by reducing the charge amount, even if the information supply is interrupted, it can be understood that the unauthorized opening / closing has been performed. Become. That is, when it is determined that the charge amount is 0, it can be considered that the charge amount has decreased at least than the terminal charge amount or the threshold value, and it is possible that improper switching has been performed. From the above, it is possible to more appropriately contribute to the improvement of crime prevention by performing fraud detection based on the decrease in the charge amount than performing fraud detection based on the increase in the charge amount of the power storage means. it is conceivable that.

(B3). Supply control switch means (delay switches 351, 361, etc.) for opening and closing the power supply path in the power supply path connecting the power storage means and the external power source,
The supply control switch means keeps the power supply path open when the external power supply is stopped, and closes the power supply path after the predetermined condition is satisfied when the power supply is started. The gaming machine according to B2, wherein the gaming machine is held in a state.

  According to B3, when power supply from the external power source is started, power storage to the power storage unit is started, and the inconvenience that the record of opening / closing detection (that is, the charge amount of the power storage unit) is changed is suppressed. Can do. In other words, it is easy to check the amount of charge in the power storage means after starting the supply of power.

  In general, in order to determine a change in the amount of charge in the power storage means, it is assumed that it is necessary to read and compare information from the power storage means using an electric device (for example, a main control device) or the like. . In order to execute such various kinds of processing, it is considered necessary to supply electric power to an electric device or the like. Therefore, a practically preferable configuration that does not require nighttime power supply can be realized by reading the charge information held in the power storage means after the supply of power from the external power source is started. In such a case, it is desirable to provide the supply control switch means described above.

  Note that “establishment of the predetermined condition” indicates, for example, the elapse of a predetermined period set in advance, the completion of the charge amount check processing of the power storage unit, or the like.

(B4). A signal is generated based on at least one of an opening operation and a closing operation of the opening / closing body provided in at least one of the opening / closing body and the support target and in a state where power supply from the external power source is cut off. Signal generating means (monitoring devices 250, 290, etc.);
A charge release path for discharging the charge of the power storage means; and a discharge control switch means (MOSFETs 354, 364, etc.) for opening and closing the charge release path based on the signal. A gaming machine according to B3, characterized by the above.

  In the gaming machine of B4, a signal is output from the signal output means based on at least one of the opening operation and the closing operation of the opening / closing body. By inputting this signal to the discharge control switch means, the charge discharge path is closed, and the charge of the power storage means is released. In addition, it is preferable that the charge discharge path is held in a closed state until the charge of the power storage unit becomes almost zero by inputting a signal from the signal output unit to the discharge control switch. In such a configuration, the discharge of the charge is continued until the charge amount of the power storage means becomes substantially zero.

  If the charge is discharged only while a signal is being input, the amount of charge discharged varies depending on various conditions such as the number of signal inputs and the length of the signal, resulting in a desired change in charge. There is no possibility. Further, usually, the electric charge stored in the power storage means is gradually released over time (so-called spontaneous discharge). For this reason, the difference between the natural discharge and the artificial discharge based on the signal from the signal generating means may be obscured, and it may be difficult to determine whether to open or close based on the amount of change in charge.

  As shown in B4, when the signal from the signal generating means is input once, and the discharge path is held in a closed state, the electric storage means discharges the charge amount to a predetermined amount (for example, zero). Continue until As a result, for example, a clear difference can be produced between the charged state and a minute signal or a small number of inputs. Therefore, it is possible to easily confirm the difference in the charge amount, thereby contributing to the improvement of the open / close detection accuracy.

  (B5). The gaming machine according to any one of B1 to B4, wherein the charge amount of the power storage unit is changed by the charge amount varying unit when at least the opening / closing body is closed.

  According to B5, the charge amount of the power storage means changes at least when the opening / closing body is closed. If the charge amount is changed only when the opening / closing body is opened, the opening / closing body is opened when the charge amount is changed, so that access to the inside of the gaming machine (for example, an electric device) is facilitated. . In such a case, there is a possibility that the power amount, the power storage means, etc. are accessed and the charge amount is illegally manipulated. If such unauthorized access or the like is performed, the opening / closing fact of the opening / closing body may be concealed.

  However, as shown in B5, if the structure is such that the amount of charge changes when the opening / closing body is closed, the opening / closing body is in a closed state, thereby suppressing access to the power storage means and the like by the opening / closing body. Is possible. For example, it is possible to store the change in the amount of charge in the power storage means in a state isolated from the outside of the gaming machine. Therefore, it is possible to suppress inconvenience such as concealment of the opening / closing fact of the opening / closing body by falsification of the charge amount or the like.

(B6). An opening / closing body (game machine main part 12 or front door frame 14) supported to be openable / closable with respect to a support target (outer frame 11 or main body frame 13);
An electric device (main control device 162, payout control device 242 and the like) that is provided on the back side or rear of the opening / closing body and operates based on electric power supplied from an external power source;
Power storage means (source capacitors 353, 363, etc.) capable of accumulating the supplied charge and releasing the stored charge;
Based on at least one of an opening operation and a closing operation of the opening / closing body provided in at least one of the opening / closing body and the support target and in which power supply from the external power source is interrupted, Charge amount changing means (monitoring devices 250, 290, MOSFETs 354, 364, etc.) for changing the charge amount,
The power storage means stores electric charges in a state where electric power is supplied from the external power source,
The gaming machine characterized in that the charge amount varying means reduces the charge amount of the power storage means based on the operation of the opening / closing body in a state where power supply from the external power source is cut off.

  According to B6, the charge of the power storage means increases based on the operation of the opening / closing body. With the configuration in which the amount of charge accumulated in the power storage unit is increased, the possibility of erroneous detection of the opening / closing body can be suppressed. Specifically, while the amount of charge from the power storage means can be reduced due to a malfunction of the power storage means or the like, it is considered that the same amount of charge is unlikely to increase due to a malfunction of the power storage means or the like. That is, if the opening / closing detection is performed by increasing the amount of charge, it is possible to make it difficult to cause the inconvenience that the opening / closing is detected even though the opening / closing is not performed.

  It is possible to combine B6 with B4 and B5 described above. By combining these, a practically preferable configuration can be realized.

  (B7). The gaming machine according to any one of B1 to B6, further comprising determination means (CPU 310) for determining whether or not the opening / closing body has been opened / closed in accordance with a power storage state of the power storage means. .

  A practically preferable configuration can be realized by providing a determination unit that determines whether to open or close depending on the storage state of the storage unit. In such a case, for example, a configuration for determining the presence / absence of an operation of the opening / closing body by comparing a power storage state when power supply is stopped and a power storage state at the time of determination by the determination unit (for example, when power supply is started) Alternatively, the presence / absence of the operation of the opening / closing body may be determined by setting a threshold value for the charge amount in advance and comparing the threshold value with a power storage state at the time of determination by the determination means (for example, when power supply is started). It is good also as a structure which determines.

  In addition, it becomes possible to put together the structure regarding an opening / closing detection in a gaming machine by arrange | positioning a determination means in a gaming machine. Thus, it is considered that opening / closing detection can be realized without depending on a hall management system (specifically, a management system or the like), thereby contributing to promotion of introduction into the hall.

  The technical ideas A1 to B7 detailed above may be arbitrarily combined with the above-described means. It is also possible to combine a plurality of technical ideas with each of the above means.

  Below, the basic composition of various game machines which can apply each above-mentioned means and each technical thought A1-B7 is shown.

Thereafter, when the rotation operation of the operation key K is released, the interlocking rod 174 and the rod receiving member 180 are returned to the initial state by the biasing force of the coil spring 192.

  Here, the operation of the locking device 170 (specifically, the hook receiving member 180) when the front door frame 14 is closed with respect to the main body frame 13 will be described.

  By turning the front door frame 14 toward the closed position with respect to the main body frame 13 from the opened state, the flange portion 65 of the front door frame 14 hits the hook receiving member 180 of the main body frame 13. More specifically, the guide inclined portion 65a of the flange portion 65 hits the contact portion 183a of the flange receiving member 180. In this way, when the front door frame 14 is further rotated in a state where the guide inclined portion 65a and the contact portion 183a are in contact with each other, the collar receiving member 180 is moved along the inclination of the guide inclined portion 65a. As described above, the hook receiving member 180 is biased by the coil spring 192, and the hook receiving member 180 is moved against the biasing force of the coil spring 192. Specifically, it is moved downward. When the collar receiving member 180 is moved by a predetermined amount, the holding section 65b of the collar section 65 and the contact section 183b are in contact with each other. That is, the collar receiving member 180 is held in a predetermined position by the collar 65 against the urging force of the coil spring 192. Hereinafter, the position in the state where the hook receiving member 180 is held in this way is referred to as a lock standby position. In this state where the hook receiving member 180 is held by the hook 65, the front door frame 14 is further rotated, whereby the holding portion 65b and the contact portion 183b are separated from each other, and the holding state of the hook receiving member 180 is changed. Canceled. By releasing the holding state in this way, the hook receiving member 180 is moved toward the original position by the biasing force of the coil spring 192. Specifically, it is moved upward. When the hook receiving member 180 moves by a predetermined amount, the contact portion 183b of the hook receiving member 180 hits the stopper portion 64a and the movement thereof is restricted. In this case, the hook portion 65 c of the hook portion 65 is hooked on the hook receiving portion 182, and the front door frame 14 is locked to the main body frame 13. Hereinafter, the position of the hook receiving member 180 in the locked state is referred to as a locked position.

  Thus, when the collar receiving member 180 moves over the collar 65 and moves from the lock standby position to the lock position, the moving speed depends on the urging force of the coil spring 192. For this reason, even if it is a case where the rotational speed of the front door frame 14 varies, the moving speed to the locking position of the collar receiving member 180 is ensured. For example, even when the front door frame 14 is closed slowly, the hook receiving member 180 moves from the lock standby position to the lock position vigorously and at the same speed every time.

  Next, an operation of the locking device 170 (specifically, the metal fitting 185) when the gaming machine main part 12 is closed with respect to the outer frame 11 will be described. By turning the gaming machine main part 12 from the opened state toward the closed position with respect to the outer frame 11, the metal fitting 185 of the gaming machine main part 12 hits the metal fitting 190 of the outer frame 11. In such a case, the hook metal 185 moves relative to the hook receiving metal 190. The relative movement of the metal fittings 185 and 190 is opposite to the relative movement of the flange portion 65 and the flange receiving member 180 described above. That is, the heel side moves and the heel receiving side does not move. Thus, although the operation mode at the time of locking of the game machine main part 12 is substantially the same as the operation mode at the time of locking of the outer frame 13, the details will be described later.

  When the hook metal 185 moves over the hook receiving metal 190 and moves from the lock standby position to the lock position, the moving speed depends on the biasing force of the coil spring 193 as in the case of the hook receiving member 180 described above. For this reason, even if it is a case where the rotational speed of the game machine main part 12 varies, the moving speed to the locking position of the metal fitting 185 is ensured.

Thereafter, when the sealing process is performed again, the locking claws are inserted into the long holes of the other sealing portions. If the history of opening the substrate box 163 is left in the substrate box 163, it can be easily found that the unauthorized opening has been performed by looking at the substrate box 163.

  A plurality of coupling pieces 165 are provided on one short side of the substrate box 163 so as to protrude laterally. These coupling pieces 165 have a one-to-one correspondence with the plurality of coupled pieces 166 formed on the mounting table 161, and the coupling pieces 165 and the coupled pieces 166 provide a space between the board box 163 and the mounting table 161.

That is, a tank 221 opened upward is provided at the uppermost portion of the back pack 201, and the game balls supplied from the island facilities of the game hall are sequentially replenished to the tank 221. A tank rail 222 that is gently inclined toward the downstream side is connected to the lower side of the tank 221, and a case rail 223 that extends in the vertical direction is connected to the downstream side of the tank rail 222. A payout device 224 is provided at the most downstream portion of the case rail 223. The game balls paid out from the payout device 224 are supplied to the game ball distribution unit 225 provided in the base portion 211 of the back pack 201 through a payout passage (not shown) provided on the downstream side of the payout device 224.

  The game ball distribution unit 225 has a function of distributing the game balls paid out from the payout device 224 to any one of the upper plate 33, the lower plate 34, and a discharge passage described later, and the inner opening 226 has been described above. The center side opening 227 communicates with the lower plate 34 via the main body side lower plate passage 123 and the front door side lower plate passage 52 through the main body side upper plate passage 122 and the front door side upper plate passage 51.

It has become. Therefore, for example, when the power supply is turned off in the normal procedure, as in the case of the game hall being closed, the state before the interruption is stored and held, but when the power is turned on while the RAM erase switch 247 is held down, the RAM data is initialized. It is like that.

  Next, a configuration for grasping the fact when the gaming machine main part 12 and the front door frame 14 are opened and closed will be described.

  As shown in FIGS. 3 and 9, the first monitoring device 250 and the second monitoring device 290 are attached to the base frame 171 of the locking device 170. The first monitoring device 250 is disposed below the upper metal fitting 185, and the opening and closing of the gaming machine main part 12 is monitored by the first monitoring device 250. On the other hand, the second monitoring device 290 is disposed above the center saddle receiving member 180, and the opening / closing of the gaming machine main part 12 is monitored by the saddle receiving member 180.

  Here, specific configurations of the first monitoring device 250 and the second monitoring device 290 will be described. The first monitoring device 250 and the second monitoring device 290 have the same configuration, and only the mounting direction of the monitoring devices 250 and 290 and the configuration provided accompanying the monitoring devices 250 and 290 are different. ing. Therefore, first, the first monitoring device 250 will be described in detail, and then the differences described above will be described. 16 is a partially enlarged view of FIG. 9, FIG. 17 is an exploded perspective view of the first monitoring device 250, and FIG. 18 is a partial end view taken along line AA of FIG.

  The first monitoring device 250 includes a magnetic unit 260 having a magnetic body, a conductor unit 270 that generates an induced electromotive force by displacement of a relative position with the magnetic unit 260, and a housing that houses both the units 260 and 270. 280. When the housing 280 is fixed to the installation portion 171c formed on the base frame 171 with a fastener such as a screw, the first monitoring device 250 is mounted on the gaming machine main portion 12 (specifically, the locking device 170). It has become. The housing 280 is made of a transparent synthetic resin material having light permeability, and the inside thereof can be visually recognized. Thereby, the internal confirmation of the 1st monitoring apparatus 250 by maintenance etc. is facilitated. The housing 280 is configured by fixing two members of the housing case body 280a and the lid case body 280b, but is not necessarily limited thereto. For example, the housing 280 may be composed of one member, or may be composed of three or more members.

  The magnetic body unit 260 includes a columnar magnetic body 261 and a housing 262 that houses the magnetic body 261. In the present embodiment, the magnetic body 261 is configured by a magnet (bar magnet). A portion of the housing 280 that faces the metal fitting 185 (hereinafter referred to as the top wall portion 281) is formed with an opening portion 282 that penetrates inside and outside, and through this opening portion 282, the magnetic body unit 260 (more specifically, A part of the housing 262) protrudes outside the housing 280.

  The magnetic unit 260 is movable relative to the conductor unit 270 fixed in the housing 280. The housing 280 is provided with a bearing portion 283 that restricts the movement of the magnetic body unit 260. By this bearing portion 283, the movement of the magnetic unit 260 in a direction other than the axial direction is restricted. More specifically, the magnetic body unit 260 is movable only in the same direction as the longitudinal direction of the base frame 171, that is, in the same direction as the moving direction of the metal fitting 185.

  Next, the conductor unit 270 will be described in detail. The conductor unit 270 includes a conductive coil 271 and a bobbin 272 to which the coil 271 is attached. Since the bobbin 272 is fixed inside the housing 280 by a fastener such as a screw, the conductor unit 270 is attached to the housing 280. The bobbin 272 has a substantially cylindrical shape extending in the same direction as the moving direction of the magnetic unit 260, and a coil 271 is spirally wound around the outer periphery thereof. A gap defined by the inner peripheral surface of the bobbin 272 constitutes a moving region 273 of the magnetic body 261. When the magnetic body unit 260 passes through the moving region 273, the relative position between the magnetic body unit 260 (specifically, the magnetic body 261) and the conductor unit 270 (specifically, the coil 271) is changed. Due to such displacement of the relative position, an induced electromotive force is generated in the coil 271. That is, the moving region 273 constitutes a region where an induced electromotive force can be generated.

  Here, the movable range of the magnetic body unit 260 will be described with reference to FIGS. 18 and 19. The bobbin 272 is formed with a stopper portion 274 that contacts the container 262. As shown in FIG. 18 and FIG. 19D, the movement of the magnetic body unit 260 to the back side of the moving region 273 is restricted by the container 262 hitting the stopper portion 274. In such a state, the amount of protrusion of the magnetic unit 260 from the housing 280 is minimized. In addition, a stopper piece 263 as a restricting member that restricts the movement of the magnetic body unit 260 is attached to the containing body 262. As shown in FIG. 19 (e), the stopper piece 263 abuts against the housing 280 (specifically, the bearing portion 283), so that the movement of the magnetic unit 260 toward the metal fitting 185 is restricted. In such a state, the amount of protrusion of the magnetic unit 260 from the housing 280 is the maximum. The stroke (movement range) L1 of the magnetic body unit 260 is defined by the stopper portion 274, the stopper piece 263, and the like.

  As described above, one end portion of the magnetic body unit 260 (specifically, one end portion of the container 262) protrudes from the housing 280 through the opening 282. An abutting portion 264 that abuts on the metal fitting 185 is formed at the protruding end of the housing 262. The contact portion 264 has a flat plate shape orthogonal to the moving direction of the magnetic body unit 260. On the other hand, an operation portion 186 a is provided at a contact portion of the metal fitting 185 with the contact portion 264. The operation portion 186 a is formed by bending the lower end portion of the metal fitting 185 and has a plate shape extending in a direction orthogonal to the moving direction of the metal fitting 185. The operation part 186a and the contact part 264 are in a state of facing each other.

  The metal fitting 185 is movably provided and is not fixed to the base frame 171 or the like. Due to the contact with the collar receiving metal 190, for example, a positional variation in the left-right direction and the front-rear direction can occur. In the present embodiment, in the direction in which the variation in position of the metal fitting 185 is assumed, the operation unit 186a has an extent that allows such variation. Specifically, the operation unit 186a has a plate shape extending in the left-right direction and the front-rear direction. Thereby, it is easy to allow the variation in the relative position of the metal fitting 185 with respect to the contact portion 264, and the contact between the two is ensured.

  In the present embodiment, the contact portion 264 has a disk shape extending radially from the moving center axis of the magnetic body unit 260. For this reason, even if the magnetic body unit 260 rotates, the relative position of the operation part 186a and the contact part 264 is difficult to shift. In other words, the magnetic unit 260 is allowed to rotate with reference to the movement center axis. The operation unit 186a is configured to contact the contact unit 264 at a position away from the track during operation of the magnetic body unit 260. As described above, the operation portion 186a is provided on the metal fitting 185, and a reaction force when the operation portion 186a presses the contact portion 264 is transmitted to the metal fitting 185. In such a case, the contact portion between the operation portion 186a and the contact portion 264 is separated from the track, and there is a possibility that inconveniences such as displacement and deformation occur in the metal fitting 185 due to the moment caused by the reaction force. . However, in this embodiment, the contact portion 264 extends toward the metal fitting 185, so that the contact portion between the operation portion 186a and the contact portion 264 can be brought close to the track. Yes. Thereby, since the moment which the metal fitting 185 produces can be reduced, the function as an operation part of the 1st monitoring device 250 can be given, ensuring the locking function.

  The outer shape of the contact portion 264 is set larger than the outer shape of the opening 282, and a coil spring 285 is disposed between the contact portion 264 and the top wall portion 281. That is, the coil spring 285 is sandwiched between the contact portion 264 and the top wall portion 281. The container 262 is inserted through the coil spring 285, and the coil spring 285 is prevented from coming off.

  With this coil spring 285, the magnetic body unit 260 is constantly urged toward the side protruding from the housing 280. Specifically, the total length of the coil spring 285 is set to be larger than the clearance C1 between the contact portion 264 and the top wall portion 281 in the state where the stopper piece 263 shown in FIG. . For this reason, the coil spring 285 is compressed when the stopper piece 263 and the bearing portion 283 are in contact, that is, when the amount of protrusion of the magnetic unit 260 from the housing 280 is maximum, and the magnetic unit 260 is It is in a state of being biased toward 185.

  As described above, the biasing direction of the magnetic unit 260 by the coil spring 285 and the biasing direction of the metal fitting 185 by the coil spring 193 are opposite to each other. The urging force of the coil spring 285 is set to be smaller than the urging force of the coil spring 193 that urges the metal fitting 185 and can lift the magnetic body unit 260 alone upward. For this reason, in a state where the contact portion 264 is pressed by the operation portion 186a, the coil spring 285 is compressed by the urging force of the coil spring 193 being won.

  Hereinafter, the opening / closing detection operation of the gaming machine main part 12 by the first monitoring device 250 will be described with reference to FIG. Since the first monitoring device 250 is configured to operate in conjunction with the movement of the locking device 170 (specifically, the metal fitting 185) when closing the gaming machine main part 12, the movement of the metal fitting 185 is also included. explain.

  FIG. 19A shows a state in which the gaming machine main part 12 is opened, FIG. 19B shows a state immediately before the gaming machine main part 12 is closed, and FIG. FIG. 19 (d) shows the state of the first monitoring device 250 at the time of FIG. 19 (a), and FIG. 19 (e) shows the first monitoring at the time of FIG. 19 (b). The state of the apparatus 250 is shown, FIG.19 (f) shows the state of the 1st monitoring apparatus 250 at the time of FIG.19 (c). When the gaming machine main part 12 is opened and then closed, the locking device is in the order of FIGS. 19 (a), (e) → FIG. 19 (b), (f) → FIG. 19 (c), (g). 170 and the first monitoring device 250 operate.

  The first monitoring device 250 operates in conjunction with the movement of the locking device 170 when the gaming machine main part 12 is closed. Specifically, with the movement (rotation) of the gaming machine main part 12 to the closed position, the metal fitting 185 also moves toward the metal fitting 190. When the gaming machine main portion 12 reaches a predetermined position, the guide inclined portion 189b of the metal fitting 185 hits the contact portion 190c of the metal fitting 190 as shown in FIG.

  As the movement of the gaming machine main body 12 continues, the relative position in the vertical direction of the saddle bracket 185 and the saddle bracket 190 changes. Specifically, the metal fitting 185 moves (ascends) along the inclination of the guide inclined portion 189b. In such a case, the metal fitting 185 moves against the urging force of the coil spring 193. As the hook 185 moves upward as described above, the operation unit 186a also moves upward. The magnetic unit 260 (specifically, the magnetic body 261) that has been pressed by the operation unit 186a moves upward in accordance with the movement of the metal fitting 185 by the urging force of the coil spring 285. As described above, when the magnetic body 261 moves toward the side away from the coil 271, the relative position between the magnetic body 261 and the coil 271 changes, and a negative voltage is generated in the coil 271. Since the movement range of the magnetic body unit 260 is set to be smaller than the movement range of the metal fitting 185, the movement of the magnetic body unit 260 stops before the movement of the metal fitting 185. The unit 260 is separated.

  When the upward movement amount of the metal fitting 185 reaches a predetermined amount, as shown in FIG. 19B, the lower end portion of the guide inclined portion 189b, that is, the lower end portion of the flange portion 189 is put on the holding portion 190b. . That is, the metal fitting 185 is held by the holding portion 190b against the urging force of the coil spring 193.

  When the gaming machine main part 12 further moves from this state, the guide inclined part 189b is separated from the holding part 190b, and the holding state is released. Thereby, the metal fitting 185 moves downward, that is, toward the first monitoring device 250 (downward) by its own weight and the biasing force of the coil spring 193. The operation part 186a hits the contact part 264 by the downward movement triggered by the movement of the gaming machine main part 12 to the closed position. Thereby, the magnetic body unit 260 is also moved in the same direction (downward) together with the metal fitting 185. Therefore, the magnetic unit 260 (specifically, the magnetic body 261) moves in the moving region 273. Thus, when the magnetic body 261 moves toward the coil 271, the relative position between the magnetic body 261 and the coil 271 changes, and a positive voltage is generated in the coil 271.

  When the magnetic body unit 260 and the metal fitting 185 move by a predetermined amount, first, the extending portion 188 of the metal fitting 185 hits the holding portion 190b, and the movement of the metal fitting 185 stops. Almost in synchronization with this, the tip of the container 262 hits the stopper portion 274, so that the movement of the magnetic unit 260 is also stopped. When the locking device 170 is in the locked state in this way, the upward movement of the magnetic body unit 260 is restricted by the metal fitting 185, and the downward movement is restricted by the stopper portion 274. For this reason, even when vibration is applied to the pachinko machine 10, it is difficult for the inconvenience that the magnetic body unit 260 moves unexpectedly and an induced electromotive force is generated.

  As described above in detail, when the gaming machine main part 12 is closed, power in the closing direction generated in the gaming machine main part 12 itself, that is, the closing operation by the operator causes the gaming machine main part 12 itself to close. The generated rotational force in the closing direction is used as an opportunity for moving the metal fitting 185. The metal fitting 185 is moved by a power source that generates power different from the rotational force of the gaming machine main part 12, that is, a coil spring 193. In this way, the positive voltage can be stably generated by moving the gutter 185 depending on the urging force of the coil spring 193 without depending on the rotational force of the gaming machine main part 12. ing.

  On the other hand, when the gaming machine main part 12 is released from the closed state, FIGS. 19 (c), (g) → FIG. 19 (b), (f) → FIGS. 19 (a), (d). The locking device 170 and the first monitoring device 250 operate in this order. Specifically, the metal fitting 185 moves upward in accordance with the turning operation of the external key. Thereby, the magnetic body unit 260 (specifically, the magnetic body 261) pressed by the operation portion 186a moves upward in accordance with the movement of the metal fitting 185 by the urging force of the coil spring 285. Thus, when the magnetic body 261 moves toward the side away from the coil 271, the relative position between the magnetic body 261 and the coil 271 changes, and a negative voltage is generated in the coil 271. In this state, by turning the gaming machine main part 12 in the opening direction, the lower end part of the flange part 189 is put on the holding part 190b. In other words, the metal fitting 185 is held by the holding portion 190b against the urging force of the coil spring 193 (see FIG. 19B). As the gaming machine main portion 12 further rotates in the opening direction, the metal fitting 185 gradually moves (descends in detail) along the inclination of the guide inclined portion 189b. As a result, the magnetic unit 260 moves together with the metal fitting 185 in the same direction (downward), the relative position between the magnetic body 261 and the coil 271 changes, and a positive voltage is generated in the coil 271. Particularly in the present embodiment, the metal fitting 185 is gradually lowered along the guide inclined portion 189b, so that a sudden change in the relative position between the magnetic body 261 and the coil 271 is suppressed. That is, the generation of positive voltage is difficult to increase. Thereby, compared with the positive voltage generated when the gaming machine main part 12 is closed, the positive voltage generated when the gaming machine main part 12 is opened is suppressed from becoming larger.

  In addition, as described above, when the gaming machine main part 12 is opened by the external key, the position of the metal fitting 185 is moved to the unlocking position as the interlocking bar 174 moves. That is, in the state where the hook metal 185 is moved to the lock release position, the position of the interlocking bar 174 is also moved to the lock release position. For this reason, when the bar metal 185 tries to return to the original position by the urging force of the coil spring 193, the interlocking bar 174 moves along with the bar metal 185. That is, when unlocked with the external key, the metal fitting 185 moves with the interlocking rod 174 in the direction of generating a positive voltage. As described in detail above, when closing the gaming machine main part 12, only the metal fitting 185 is moved by the biasing force of the coil spring 193, while when opening the gaming machine main part 12 by an external key operation, The metal fitting 185 and the interlocking rod 174 are moved by the biasing force of the coil spring 193. As described above, the number of objects to be moved by the urging force increases, so that the displacement speed of the metal fitting 185 is difficult to increase. In other words, the increase in the number of objects that are moved by the biasing force of the coil spring 193 makes it easier to suppress the generation of positive power.

  Here, the relative positions of the gaming machine main part 12 and the outer frame 11 when the first monitoring device 250 operates will be described. The locking device 170 and the first monitoring device 250 are arranged inside the outer frame 11 with the gaming machine main part 12 being closed with respect to the outer frame 11. In other words, the locking device 170 and the first monitoring device 250 are arranged behind the boundary portion between the gaming machine main part 12 and the outer frame 11. More specifically, the resin base 71 is formed with an attachment stepped portion 71b for mounting the locking device 170 so as to protrude rearward of the pachinko machine 10, and the locking stepped portion 71b allows the locking device 170 to be mounted. Is arranged behind the boundary portion between the gaming machine main part 12 and the outer frame 11. The gaming machine main part 12 (specifically, the resin base 71) and the outer frame 11 overlap with each other by the attachment stepped part 71b. This amount of overlap is set to be larger than the amount of displacement of the gaming machine main part 12 required for the operation of the metal fitting 185, specifically, the amount of displacement in the front-rear direction at the rotating tip portion of the gaming machine main part 12. For this reason, when the saddle fitting 185 and the saddle receiving fitting 190 are shifted to the locked state shown in FIG. 19 (a) → FIG. 19 (b) → FIG. Access to the locking device 170 and the first monitoring device 250 is difficult.

  Similarly to the first monitoring device 250, the second monitoring device 290 includes a housing 291, a magnetic body unit 292 (magnetic body 293), and a conductor unit 294 (coil 295). An installation portion 171d for installing the second monitoring device 290 is formed on the base frame 171. The second monitoring device 290 is fixed to the installation portion 171d by a fastener such as a screw. Further, the second monitoring device 290 is arranged upside down with respect to the first monitoring device 250. That is, the magnetic unit 292 protrudes toward the collar receiving member 180 disposed below, and the operation direction thereof is set to be opposite to the operation direction of the first monitoring device 250. Thus, the configuration of the second monitoring device 290 is the same as the configuration of the first monitoring device 250, and only the mounting direction is different.

  The operation itself of the second monitoring device 290 is the same as that of the first monitoring device 250, but the operation of the locking device 170 accompanying it is slightly different. Hereinafter, the operation of the second monitoring device 290 accompanying the operation of the locking device 170 will be briefly described. When the front door frame 14 is closed, the hook receiving member 180 of the locking device 170 is displaced based on the movement of the hook metal 63 of the front door frame 14 in the closing direction. Specifically, when the guide inclined portion 65a of the metal fitting 63 hits the contact portion 183a of the flange receiving member 180, the flange receiving member 180 moves away from the second monitoring device 290 along the guide inclined portion 65a ( Move down). Thereby, the relative positions of the magnetic body unit 292 and the conductor unit 294 of the second monitoring device 290 change, and a negative voltage is generated in the second monitoring device 290. When the front door frame 14 further moves toward the closed position, the holding portion of the metal fitting 63 and the contact portion 183b of the metal receiving member 180 are in contact, that is, the metal receiving member 180 is held by the metal fitting 63. It becomes a state. In this state, the scissor receiving member 180 is completely separated from the second monitoring device 290, and the magnetic unit 292 of the second monitoring device 290 is in the state of most protruding from the housing 291 (FIG. 19 (similar state to (b) and (e)). As the front door frame 14 reaches the closed position, the holding state of the hook receiving member 180 is released, and the hook receiving member 180 moves toward the position before displacement by the biasing force of the coil spring 192. As a result, the magnetic body unit 292 of the second monitoring device 290 is pushed into the housing 291 and a positive voltage is generated.

  As shown in FIG. 3 and the like, a relay board 300 is provided between the first monitoring device 250 and the second monitoring device 290. The relay substrate 300 is fixed to the base frame fixing portion 171a of the base frame 171 by fastening means such as screws. Wiring (harness) (not shown) from both monitoring devices 250 and 290 is connected to the relay board 300, and the relay board 300 is connected to the main controller 162 via wiring (not shown). Details of these wirings will be described later.

  Next, the electrical configuration of the pachinko machine 10 will be described based on the block diagram of FIG. In FIG. 20, a power supply line is indicated by a double line arrow, and a signal line is indicated by a solid line arrow.

  A main control board 301 provided in the main controller 162 incorporates a main control circuit 302 and a power failure monitoring circuit 303 (power failure monitoring circuit). The main control circuit 302 is equipped with a CPU 310.

  The CPU 310 temporarily stores various control programs executed by the CPU 310 and a ROM 312 (nonvolatile information storage means) that stores fixed value data, and various data temporarily when the control program stored in the ROM 312 is executed. A RAM 313 (volatile information storage means), which is a memory for storing data, and various circuits such as an interrupt circuit, a timer circuit, and a data input / output circuit are incorporated. The CPU 310, the ROM 312 and the RAM 313 may be individually configured as one chip. The same applies to CPUs of other control devices.

  The RAM 313 is configured to retain data by supplying data storage holding power from the power supply and launch control board 314 provided in the power supply and launch control device 243 even after the pachinko machine 10 is powered off.

  The CPU 310 is provided with an input port and an output port. Connected to the input side of the CPU 310 are a power failure monitoring circuit 303 provided on the main control board 301, a payout control board 315 provided on the payout control device 242, a counter circuit described later, and other switches not shown. In this case, a power supply and launch control board 314 is connected to the power failure monitoring circuit 303, and power is supplied to the CPU 310 (main control circuit 302) via the power failure monitoring circuit 303.

  On the other hand, a power failure monitoring circuit 303, a payout control board 315, and a relay terminal board 316 are connected to the output side of the CPU 310. Various commands such as prize ball commands are output to the payout control board 315. Various commands are output from the main control circuit 302 to the sound lamp control board 317 provided in the sound lamp control device 143 via the relay terminal plate 316.

  The power failure monitoring circuit 303 relays between the main control circuit 302 and the power source and launch control board 314, and monitors a DC stable voltage of 24 volts, which is the maximum voltage output from the power source and launch control board 314. When this voltage is less than 22 volts, it is determined that the power supply has been cut off, and a power failure signal is transmitted to the main control circuit 302. In the main control circuit 302, by confirming the input of the power failure signal, a power failure process (power failure process) to be described later is executed based on the confirmation result.

  The payout control board 315 performs payout control of prize balls and rental balls by the payout device 224. The CPU 338 that is an arithmetic unit includes a ROM 339 that stores a control program executed by the CPU 338, fixed value data, and the like, and a RAM 340 that is used as a work memory or the like.

  Similar to the RAM 313 of the main control circuit 302, the RAM 340 of the payout control board 315 is configured such that the data storage holding power is supplied from the power supply and the launch control board 314 even after the power of the pachinko machine 10 is shut off. It has become.

  The CPU 338 of the payout control board 315 is provided with an input / output port. A main control circuit 302, a power and launch control board 314, and a backpack board 229 are connected to the input side of the CPU 33338. Further, the main control circuit 302 and the back pack substrate 229 are connected to the output side of the CPU 338.

  The power source and launch control board 314 includes a power source unit 314a and a launch control unit 314b. The power supply unit 314a is connected to, for example, a commercial power supply (external power supply) in a game hall or the like. Then, based on the external power supplied from the commercial power supply, necessary operating power is generated for each of the main control circuit 302, the payout control board 315, etc., and the generated operating power is indicated by a double line arrow. This is supplied to the main control circuit 302, the payout control board 315, etc. through the route. As an outline, the power supply unit 314a takes in the AC 24 volt power supplied via the backpack connection board 229, and generates + 12V power for driving various switches, motors, etc., + 5V power for logic, and the like. The + 12V power and + 5V power are supplied to the main control circuit 302, the payout control board 315, the counter circuit, and the like.

  The launch control unit 314b is responsible for launch control of the game ball launch mechanism 110 according to the operation of the game ball launch handle 41 by the player, and the game ball launch mechanism 110 is driven when predetermined launch conditions are met. The

  The power supply and launch control board 314 is equipped with a data storage holding capacitor 321c as power supply means for power interruption. A power storage unit 314a is connected to the data storage holding capacitor 314c, and is charged when the power of the pachinko machine 10 is ON (when power is supplied from an external power supply). Further, the data storage holding capacitor 314c is connected to the VBB terminal of the CPU 310 in the main control circuit 302. When the power supply of the pachinko machine 10 is in the OFF state, or when a power failure occurs in the commercial power supply, etc. In this case, the data storage holding capacitor 314c is discharged, and the data storage holding power is supplied to the RAM 313. Therefore, even in such a situation, the data stored in the RAM 313 is held without being erased while the data storage holding power is supplied from the data storage holding capacitor 314c.

  Incidentally, the electric power charged in the data storage / holding capacitor 314c is used for storing and holding data in the RAM 313 and other RAMs of the main control circuit 302, and is not used for operating devices such as an electric actuator. The capacity of the data storage capacitor 314c is relatively large, and the information stored in the RAM 313 before the power is shut off is held within a predetermined period (for example, 1 day or 2 days). Further, the power supply means for power interruption is not limited to the data storage holding capacitor, and may be a battery or a non-rechargeable battery. In the case of a non-rechargeable battery, it is not necessary to store power in the power supply means for power interruption when the power of the pachinko machine 10 is ON, but it is necessary to replace it periodically.

  Further, the power supply and launch control board 314 is provided with a power failure processing capacitor different from the data storage holding capacitor 314c. In the power supply and launch control board 314, even after the DC stable 24 volt power supply becomes less than 22 volts, by discharging from the power failure processing capacitor, a time sufficient for execution of the power failure processing described later, The output of 5 volts, which is a drive power source for the control system, is configured to maintain a normal value. Thereby, the main control circuit 302 and the like can normally execute and complete the power failure process.

  The sound lamp control board 317 controls the various lamp units 23 to 25, the speaker unit 26, and the display control device 318. The CPU 341 that is an arithmetic unit includes a ROM 342 that stores a control program executed by the CPU 341, fixed value data, and the like, and a RAM 343 that is used as a work memory or the like.

  The CPU 341 of the sound lamp control board 317 is provided with an input / output port. A main control circuit 302 is connected to the input side of the CPU 341 by relaying to the relay terminal plate 316. Based on various commands output from the main control circuit 302, various lamp units 23 to 25, a speaker unit 26, and The display control device 318 is controlled. The display control device 318 controls the symbol display device 91 based on a display command input from the sound lamp control board 317.

  In the present embodiment, a characteristic configuration is provided for opening / closing detection of the gaming machine main part 12 and the front door frame 14. Therefore, this characteristic configuration will be described based on the block circuit diagram shown in FIG. The configuration associated with the first monitoring device 250 and the configuration associated with the second monitoring device 290 are the same. Therefore, here, the configuration associated with the first monitoring device 250 will be described in detail, and the configuration associated with the second monitoring device 290 will be briefly described later.

  As described above, the first monitoring device 250 includes the coil 271 having conductivity. One end of the coil 271 is grounded (grounded) to the iron locking device 170. The other end of the coil 271 is connected to the relay substrate 300 via the signal line LN1. The signal line LN1 is detachably attached to a connector CN1 provided on the first monitoring device 250 and a connector CN2 provided on the relay board 300. Note that the signal line LN1 may be attached by fixing means such as solder without using a connector.

  The relay board 300 is connected to the main control board 301 of the main controller 162 via the harness H. More specifically, the harness H is detachably attached to a connector CN3 provided on the relay board 300 and a connector CN4 provided on the main control board 301. The signal output from the first monitoring device 250 is configured to be input to the main control board 301 via the signal line LN2 configuring the harness H.

  The main control board 301 is connected to the power supply unit 314a of the power supply device 243 via the power supply line ELN1. The power from the power supply unit 314a is supplied to the main control board 301 by the power supply line ELN1. The electric power supplied via the power supply line ELN1 is roughly divided into an operating power for the CPU 310 and an operating power for the first counter circuit 320 in the main control board 301. The CPU 310 is operated by the power branched for the CPU 310, and various processes described later are executed.

  Hereinafter, the first counter circuit 320 will be described in detail. The first counter circuit 320 has a counter function that counts the number of times a predetermined signal is input from the first monitoring device 250 via the signal lines LN1 and LN2. More specifically, the counter is composed of T flip-flops 321 and 322, and a first T flip-flop 321 to which a signal from the first monitoring device 250 is input and an output of the first T flip-flop 321 are input. The second T flip-flop 322 is connected in series.

  A Zener diode 323 is connected between the first T flip-flop 321 and the connector CN4 so as to be reverse-biased with respect to the first monitoring device 250. The Zener diode 323 is grounded, and the voltage is stabilized by the Zener diode 323. Specifically, when a positive voltage larger than a predetermined value is generated in the first monitoring device 250, the positive voltage is suppressed to a predetermined magnitude by the Zener diode 323. This avoids the disadvantage that an excessively large positive voltage is input to the first T flip-flop 321. In the present embodiment, in particular, a voltage generated by electromagnetic induction accompanying the operation of the locking device 170 is used as the open / close detection signal. As described above, by using the Zener diode 323, it is possible to prevent a voltage larger than expected due to the variation in operation of the locking device 170 from being input to the first T flip-flop 321. As a result, the first T flip-flop 321 is protected.

  Further, the voltage generated by the electromagnetic induction can be reversed in polarity depending on the operation direction of the locking device 170. Specifically, as described above, a positive voltage is generated when the magnetic body 261 moves toward the coil 271, and a negative voltage is generated when the magnetic body 261 moves away from the coil 271. When a negative voltage is generated in the first monitoring device 250, a current flows through the coil 271 via the grounded Zener diode 323, and it is difficult for the negative voltage to be input to the first T flip-flop 321.

  The first T flip-flop 321 outputs a C input terminal 321a to which the voltage is input, a T input terminal 321b to which power supplied from the power supply line ELN1 is input, and a Q output that outputs an operation result of the first T flip-flop 321. Terminal 321c. An output signal from the Q output terminal 321c, that is, a voltage generated at the Q output terminal 321c according to the voltage input from the C input terminal 321a and the input voltage (HI level or LOW level) detected at the T input terminal 321b. It has a changing structure. More specifically, when the input voltage detected at the T input terminal 321b is at the HI level, the output signal from the Q output terminal 321c is set at the HI level based on the fall of the voltage input from the C input terminal 321a. It can be switched at the LOW level. The output signal thus set is output to the input port of the CPU 310 and the second T flip-flop 322 via the Q output terminal 321c.

  The second T flip-flop 322 has the same configuration as the first T flip-flop 321. Specifically, the C input terminal 322a connected to the Q output terminal 321c of the first T flip-flop 321, the T input terminal 322b to which the power supplied from the power supply line ELN1 is input, and the operation of the second T flip-flop 322 Q output terminal 322c for outputting the result. A signal from the Q output terminal 322c (specifically, at the Q output terminal 322c) according to the signal input from the C input terminal 322a and the input voltage (HI level or LOW level) detected at the T input terminal 322b. Voltage) can be switched between the HI level and the LOW level. The signal output from the Q output terminal 322c is output to the input port of the CPU 310. In this manner, the output signals from the T flip-flops 321 and 322 are input to the CPU 310, whereby the CPU 310 can grasp the state of the first counter circuit 320 (specifically, the number of counts). Yes.

  The first counter circuit 320 is provided with a capacitor 324. The capacitor 324 is supplied with power from the power line ELN1 and stored in the state where the power of the pachinko machine 10 is ON. On the other hand, when the power supply is OFF, the capacitor 324 is discharged, so that driving power is supplied to the T flip-flops 321 and 322. Note that the capacity of the capacitor 324 is relatively large, and the T flip-flops 321 and 322 can be maintained in a state where they can be driven for a predetermined period (for example, 1 day or 2 days).

  A diode 325 is connected between the capacitor 324 and the power supply device 243 in the power supply line ELN 1 so as to be reverse-biased with respect to the capacitor 324. More specifically, the diode 325 is disposed between the capacitor 324 and the CPU 310, and the diode 325 prevents the electric charge accumulated in the capacitor 324 from being supplied to the CPU 310 or the like. That is, the charge stored in the capacitor 324 is supplied only to the first counter circuit 320 (specifically, each T flip-flop 321 and 322).

  Next, a specific example of a series of flows when the first counter circuit 320 operates will be described in detail with reference to FIG. FIG. 22 is an explanatory diagram for explaining the switching timing of the detection signal pattern from the first counter circuit 320. In the upper part of FIG. 22, the opening / closing operation with respect to the outer frame 11 of the gaming machine main part 12 is shown in a simplified manner, and below that is the operation of the first monitoring device 250 accompanying the opening / closing operation of the gaming machine main part 12. Is shown in a simplified manner. In the first monitoring device 250, the state where the magnetic body unit 260 is raised to the upper limit position is UP, and the state where the magnetic body unit 260 is lowered to the lower limit position is DOWN.

  FIG. 22A shows the operation of the first counter circuit 320 accompanying the opening operation of the gaming machine main part 12, and FIG. 22B shows the operation of the first counter circuit 320 accompanying the closing operation of the gaming machine main part 12. 22 (c) shows the operation of the first counter circuit 320 accompanying the second closing operation of the gaming machine main unit 12, and FIG. 22 (d) shows the third closing operation of the gaming machine main unit 12. The operation of the first counter circuit 320 is shown. Since the operation of the first counter circuit 320 is common when the power is turned on and when the power is turned off, the operation when the power is turned off will be described in detail, and the operation when the power is turned on will be briefly described later.

  As shown in FIG. 22 (a), the unlocking operation is performed by the operation key K in a state where the gaming machine main part 12 is closed with respect to the outer frame 11, the first monitoring device 250 Negative voltage is generated. This negative voltage is suppressed by the Zener diode 323, and a change in voltage input to the C input terminal 321a is suppressed. When the gaming machine main part 12 is rotated after the unlocking operation, a positive voltage is generated in the first monitoring device 250. Based on the generation of the positive voltage, a change occurs in the voltage at the C input terminal 321a. In such a state, a predetermined voltage is applied to the T input terminal 321b by the capacitor 324. That is, the voltage at the T input terminal 321b is maintained at the HI level. On condition that the voltage of the T input terminal 321b is at the HI level, the change of the output signal from the Q output terminal 321c is permitted. Specifically, the output signal pattern from the Q output terminal 321c can be switched between two states of a LOW level and an HI level based on a change in voltage at the C input terminal 321a, more specifically, a voltage fall. Yes. For example, in the present embodiment, since the signal from the Q output terminal 321c before the opening operation is at the LOW level, it can be switched to the HI level.

  The first T flip-flop 321 is set with a threshold value (specifically, a lower limit value of the voltage) for recognizing only a desired voltage change as a signal, avoiding misidentifying noise at the C input terminal 321a as a signal. ing. As described above, the positive voltage generated in association with the opening operation of the gaming machine main unit 12 is difficult to increase, and the voltage from the Q output terminal 321c is set on condition that the voltage is equal to or lower than a preset threshold value. Changes in the output signal are postponed. That is, the output signal from the Q output terminal 321c is held at the LOW level.

  The output signal from the Q output terminal 321c is input to the C input terminal 321a of the second T flip-flop 322. Similarly to the first T flip-flop 321, the second T flip-flop 322 is allowed to change the output signal from the Q output terminal 322c based on the fact that the voltage at the T input terminal 322b is maintained at the HI level by the capacitor 324. It is in a state. Specifically, the output signal pattern from the Q output terminal 321c can be switched between the LOW level and the HI level on the basis of a change in the voltage at the C input terminal 321a, specifically, the fall of the voltage. For example, in the present embodiment, since the signal from the Q output terminal 322c before the opening operation is at the LOW level, it can be switched to the HI level. However, switching of the output signal from the Q output terminal 321c is postponed because the signal at the C input terminal 321a is maintained at the LOW level, that is, the signal does not fall.

  When the gaming machine main unit 12 is rotated in the closing direction from the open state, a negative voltage is first generated in the first monitoring device 250 (see FIG. 22B). This negative voltage is suppressed by the Zener diode 323, and a change in voltage input to the C input terminal 321a is suppressed. When the gaming machine main part 12 is rotated to the closed position, a positive voltage is generated in the first monitoring device 250. An output signal from the Q output terminal 321c of the first T flip-flop 321 based on the fall of the positive voltage on condition that the positive voltage exceeds the threshold and the voltage of the T input terminal 321b is at the HI level. Is switched from the LOW level to the HI level. Whether the output signal from the Q output terminal 322c of the second T flip-flop 322 can be switched is determined on the condition that the signal level of the Q output terminal 321c is changed and the voltage of the T input terminal 321b is at the HI level. . Specifically, since the input signal at the C input terminal 322a rises from the LOW level to the HI level and the falling of the signal is not confirmed, the switching of the output signal from the Q output terminal 322c is postponed. That is, the output signal from the Q output terminal 322c is maintained at the LOW level. That is, by detecting the first opening of the gaming machine main part 12, the signal output from the first T flip-flop 321 is switched from the LOW level to the HI level, and the signal output from the second T flip-flop 322 is LOW. Maintains the level.

  The operation of each of the T flip-flops 321 and 322 when the second opening operation of the gaming machine main unit 12 is performed is the same as the operation when the first opening described above is performed, so the description will be given. Omit.

  As shown in FIG. 22C, when the gaming machine main unit 12 is closed again after the second opening, a negative voltage and a positive voltage are generated as in the first closing operation. On the condition that the voltage of the T input terminal 321b is at the HI level, the output signal from the Q output terminal 321a of the first T flip-flop 321 is switched from the HI level to the LOW level based on the fall of the positive voltage. The output signal from the Q output terminal 322c of the second T flip-flop 322 is changed from the LOW level on the condition that the signal changes, specifically, the fall of the signal and the voltage of the T input terminal 321b is at the HI level. Switch to HI level. That is, by detecting the second opening of the gaming machine main unit 12, the signal output from the first T flip-flop 321 is switched to the LOW level and the signal output from the second T flip-flop 322 is switched to the HI level.

  Next, the operation of each of the T flip-flops 321 and 322 based on the third opening / closing operation of the gaming machine main unit 12 will be described. Note that the operations of the T flip-flops 321 and 322 associated with the opening operation are the same as the operations at the first opening described above, and thus the description thereof is omitted.

  As shown in FIG. 22 (d), when the gaming machine main part 12 is closed again after the third opening, a negative voltage and a positive voltage are generated as in the first and second closing operations. To do. On the condition that the voltage of the T input terminal 321b is at the HI level, the output signal from the Q output terminal 321a of the first T flip-flop 321 is switched from the LOW level to the HI level based on the fall of the plus voltage. The output signal from the Q output terminal 322c of the second T flip-flop 322 is maintained at the HI level when the output signal from the first T flip-flop 321 falls. That is, by detecting the third opening of the gaming machine main part 12, the signal output from the first T flip-flop 321 is switched from the LOW level to the HI level, and the signal output from the second T flip-flop 322 is HI. The level is maintained.

  When the fourth opening of the gaming machine main unit 12 is detected based on the closing operation of the gaming machine main unit 12, the signal output from the first T flip-flop 321 is switched to the LOW level and output from the second T flip-flop 322. The signal to be switched is also switched to the LOW level. As a result, the state returns to the same state as shown in FIGS. That is, by detecting the opening of the gaming machine main part 12 four times, the mode of output from each of the T flip-flops 321 and 322 changes with (b) → (c) → (d) → (b) as one cycle. To do. When the gaming machine main part 12 is opened for the fifth time and thereafter, the mode of output from each of the T flip-flops 321 and 322 is switched based on the above cycle every time the gaming machine main part 12 is opened.

  The operation mode of the first counter circuit 320 described in detail above is the same even when the power is turned on. More specifically, the only difference is that the voltage generated at each of the T input terminals 321b and 322b when the power is turned on is not the capacitor 324 but the power supply device 243, and the output from each of the T flip-flops 321 and 322 is different. The mode is switched in the order of (b) → (c) → (d) → (b) in the same manner as when the power is turned off.

  Here, the second counter circuit 330 and the configuration associated therewith will be briefly described.

  As described above, the second monitoring device 290 includes the conductive coil 295, and one end of the coil 295 is grounded (grounded) to the iron locking device 170. The other end of the coil 295 is connected to the relay substrate 300 via the signal line LN3. The signal line LN3 is detachably attached to a connector CN5 provided on the first monitoring device 250 and a connector CN6 provided on the relay board 300. The harness H described above has a signal line LN4, and a signal from the second monitoring device 290 is supplied to the main control board 301 (specifically, the second counter circuit 330) via the signal line LN4.

  Similar to the first counter circuit 320, the second counter circuit 330 is provided with T flip-flops 331 and 332 and a Zener diode 333. The second counter circuit 330 is also configured to be supplied with power from the power supply line ELN1 in a branched manner. Specifically, both counter circuits 320 and 330 are arranged in parallel. The second counter circuit 330 is provided with a capacitor 334 that is separate from the capacitor 324, and the driving power of the T flip-flops 331 and 332 when the power supply from the power supply device 243 is OFF by the capacitor 334. It is secured. Further, a diode 335 is connected to the capacitor 334, and the electric charge stored in the capacitor 334 by the diode 335 is supplied only to the second counter circuit 330 (specifically, the T flip-flops 331 and 332). Yes.

  Next, each control process executed by the CPU 310 of the main controller 162 will be described with reference to the flowcharts of FIGS. The processing of the CPU 310 is roughly divided into main processing that is started when the power is turned on, timer interrupt processing that is started periodically (in this embodiment, at a cycle of 2 msec), and a power failure signal to the NMI terminal (non-maskable terminal). For convenience of explanation, the NMI interrupt process and the timer interrupt process will be described first, and then the main process will be described.

  FIG. 23 shows an NMI interrupt process, which is executed when the power of the pachinko machine 10 is shut off due to the occurrence of a power failure or the like. That is, when the power of the pachinko machine 10 is cut off due to the occurrence of a power failure or the like, a power failure signal is output from the power failure monitoring circuit 303 to the NMI terminal of the CPU 310, and the CPU 310 interrupts the current control and starts the NMI interrupt process. . In the NMI interrupt processing, the power failure flag is set in the power failure flag storage area provided in the RAM 313 in step S101, and this processing is terminated. Thereafter, when it is confirmed that the power failure flag is set in the normal processing described later, the power failure processing is executed.

  Next, timer interrupt processing will be described with reference to the flowchart of FIG.

  In step S201, signal reading processing from various switches, the payout control board 315, and the like is executed, and then start winning processing is executed in step S202.

  In the start winning process, it is determined whether or not the game ball has won the operating port 84 based on the signal input from the operating port switch 154. And when a game ball has won a prize in the operation slot 84, the winning is a big hit with respect to the prize, provided that the number of reserved balls in the first specific lamp section 93 and the symbol display device 91 is less than the upper limit value. A process of storing in the RAM 313 a counter value serving as an index as to whether or not to generate is executed. If the counter value is a value corresponding to the occurrence of the big win, the big win will occur in the game times corresponding to the winning. That is, in the start winning process, a lottery function (transition determination means) for transitioning to a special gaming state such as a big win is performed.

  After the start winning process, the CPU 310 once ends the timer interrupt process. In the timer interrupt process, a process of updating a counter value serving as an index as to whether or not to generate a jackpot may be executed.

  Next, the main process that is started upon reset when power is turned on will be described with reference to the flowchart of FIG.

  First, in step S301, an initial setting process associated with power-on is executed. Specifically, a wait process is executed for about 1 second, for example, to wait for the slave control board (such as the payout control board 315) to be operable. In the subsequent step S302, access to the RAM 313 is permitted.

  Thereafter, in step S303, it is determined whether or not the RAM erase switch 247 provided in the power supply and launch control device 243 is turned on. In subsequent step S304, whether or not the power failure flag is stored in the power failure flag storage buffer of the RAM 313 is determined. Determine. In step S305, a RAM determination value is calculated. In subsequent step S306, it is determined whether or not the RAM determination value matches the RAM determination value stored when the power is turned off, that is, the validity of the stored data. The RAM determination value is a checksum value at a work area address of the RAM 313, for example. It is also possible to determine the validity of the stored data based on whether or not the keywords written in a predetermined area of the RAM 313 are correctly stored.

  As described above, in the pachinko machine 10, when RAM data is initialized when the power is turned on, for example, at the start of business in the hall, the power is turned on while pressing the RAM erase switch 247. Therefore, if the RAM erase switch 247 is pressed, the process proceeds to steps S307 to S310. Similarly, when the information on occurrence of power shutdown is not set, or when an abnormality of data stored and held is confirmed by the RAM determination value (checksum value or the like), the process proceeds to steps S307 to S310.

  In step S307, an audio lamp initialization command is output to the audio lamp controller 143. Thereby, the initialization of RAM data, the abnormality of the data stored and held by the RAM judgment value, etc. are notified. In the subsequent step S308, a payout initialization command or the like is output in order to initialize the payout control board 315 or the like as the slave control board. In subsequent step S309, the used area of the RAM 313 is cleared to 0, and in step S310, initialization processing of the RAM 313 is executed. Thereafter, interrupt permission is set in step S311, and the process proceeds to normal processing described later.

  On the other hand, if the RAM erase switch 247 has not been pressed, the process proceeds to step S312 on condition that the power failure flag is stored and that the RAM determination value (checksum value, etc.) is normal. In step S312, the power failure flag stored in the power failure flag storage buffer is cleared. In the subsequent step S313, a power recovery command for returning the slave control board to the gaming state before power-off is output. Thereafter, the power recovery opening monitoring process in steps S314 to S317 is executed. The power recovery opening monitoring process will be described later in detail. Thereafter, interrupt permission is set in step S311, and the process proceeds to normal processing described later. Thereby, it returns to the state before power-off.

  Next, normal processing will be described using the flowchart of FIG. In this normal process, the main process of the game is executed.

  In the normal process, in step S401, output data such as a command updated in the previous process is output to each control board on the slave side. Specifically, the command set in the command setting process described later is output to the payout control board 315 and the like. In addition, a stop symbol command, a variation mode command, and the like are output to the voice lamp control device 143 when the symbol display device 91 displays the variation of the first symbol.

  In a subsequent step S402, a first specific lamp unit control process for switching the color displayed on the first specific lamp unit 93 is executed. In the first specific lamp unit control process, jackpot determination, on / off control of a light source switch of an LED lamp disposed in the first specific lamp unit 93, and the like are performed. Then, in the first specific lamp control process, when it is determined that the jackpot is generated based on the counter value stored in the start winning process, the gaming state is shifted to the jackpot state. That is, in the first specific lamp control process, a function for shifting to the special gaming state (transition means) is performed. In the first specific lamp unit control process, the symbol display setting by the symbol display device 91 is also performed.

  After the first specific lamp unit control process, a special winning opening opening / closing process is executed in step S403. In the big prize opening / closing process, the big prize opening of the variable prize winning device 83 is opened or closed in the case of the big hit state. That is, it is determined whether the big winning opening is opened for each round of the big hit state, and whether the maximum opening time of the big winning opening has passed or whether a predetermined number of game balls have been won in the big winning opening. The determination as to whether or not the prescribed number has been won is made by confirming the above-described counter for the big prize opening. When either of these conditions is satisfied, the special winning opening is closed. In other words, the special game state progression function (progress means) is performed in the special prize opening / closing process.

  Thereafter, in step S404, a second specific lamp unit control process for switching the color displayed on the second specific lamp unit 94 is executed. In the second specific lamp control process, switching of the display color in the second specific lamp unit 94 is started on the condition that the number of held gate balls is 1 or more. At this time, the display color switching time is also set. When the electric accessory attached to the operation port 84 is opened for a predetermined time, a stop display of a predetermined color is performed on the second specific lamp unit 94.

  After step S404, a game ball launch control process is executed in step S405. In the game ball launch control process, the game ball launch mechanism 110 is once in a predetermined period (for example, 0.6 sec) on condition that a launch permission signal is input from the launch control unit 314b of the power source and launch control board 314. The solenoid 111 is excited. Thereby, the game ball on the launch rail 112 is launched toward the game area. Incidentally, the launch permission signal is input to an input port other than the input port 311 in the CPU 310, and it is confirmed whether or not there is a launch permission signal at the input port in the game ball launch control process.

  In a succeeding step S406, it is determined whether or not a power failure flag is stored in a power failure flag storage buffer provided in the RAM 313. If the power failure flag is not stored, the last process of the plurality of processes that are repeatedly executed is completed, so whether or not the execution timing of the next normal process is reached in step S407, that is, the previous normal process It is determined whether a predetermined time (4 msec in this embodiment) has elapsed since the start of the process. If the predetermined time has not elapsed, the process returns to step S406, and if the predetermined time has elapsed, the process returns to step S401.

  On the other hand, if the power failure flag is stored in step S406, it means that the power supply has been cut off. Therefore, the power failure processing after step S408 is executed. That is, in step S408, the generation of timer interrupt processing is prohibited. In the subsequent step S409, a power interruption update process is executed. This power interruption update process will be described later. Thereafter, in step S410, a power failure command indicating that the power supply has been shut off is output to another control board. In step S411, the RAM determination value is calculated and stored. After the access to the RAM 313 is prohibited in step S412, the infinite loop is continued until the power supply is completely shut down and the process cannot be executed. Even after the power supply is completely shut down, the data storage holding power is supplied from the power supply and the data storage holding capacitor 321c of the launch control board 314. Therefore, the information stored in the RAM 313 before the power shutdown is kept as it is. In a predetermined period (for example, 1 day or 2 days).

  Next, an electrical configuration relating to monitoring of opening of the gaming machine main part 12 and the front door frame 14 will be described based on the block diagram of FIG.

  A first monitoring device 250 and a second monitoring device 290 are electrically connected to the main control device 162 (specifically, the main control board 301). More specifically, the first monitoring device 250 and the second monitoring device 290 are electrically connected to the first counter circuit 320 and the second counter circuit 330 of the main control board 301. Each of these counter circuits 320 and 330 is connected to the CPU 310 of the main controller 162, and the CPU 310 based on the signals inputted from the first counter circuit 320 and the second counter circuit 330 by the CPU 310 and the front door. The fact of opening and closing the frame 14 is grasped.

  In this case, the RAM 313 of the CPU 310 is provided with a storage area 313a for the main part of the gaming machine and a storage area 313b for the front door frame. The detection state of the first counter circuit 320 grasped during power-on is stored in the storage area 313a for the main part of the gaming machine, and the detection state of the second counter circuit 330 grasped during power-on is stored for the front door frame. It is stored in the area 313b. As described above, the RAM 313 is configured so that the power for holding data storage is supplied even when the power of the pachinko machine 10 is shut off, and the data is stored and held. The detected state that has been set is stored and held within a range in which power for holding data storage is supplied. The CPU 310 determines whether or not the gaming machine main part 12 and the front door frame 14 are opened during power-off based on the detection state information output from the counter circuits 320 and 330, and the determination result. The specific output process is executed based on the above. It should be noted that the information can be integrated by collecting the opening / closing detection states of the gaming machine main part 12 and the front door frame 14 and stored as one information in one storage area provided in the RAM 313.

  Here, each control process executed by the CPU 310 of the main controller 162 regarding the opening of the gaming machine main part 12 and the front door frame 14 will be described.

  First, the process executed in the normal process (FIG. 26) will be described.

  In the normal processing, when the power failure flag is set in the NMI interrupt processing, the processing at power failure in steps S408 to S412 is executed as described above. In the power failure process, the power interruption update process is executed in step S409 for the first counter circuit 320 and the second counter circuit 330.

  In the power interruption updating process, as shown in the flowchart of FIG. 28, first, a signal reading process is executed in step S601. In this signal reading process, signals (electric signal patterns) input from the first counter circuit 320 and the second counter circuit 330 are read. The information of the read signal is stored and held in a register of the CPU 310. In the subsequent step S602, a gaming machine main part update process is executed. It should be noted that the signal reading process from each counter circuit 320, 330 is not performed as a power interruption process, but the signal reading process from each counter circuit 320, 330 is performed in the timer interrupt process shown in FIG. It is also possible to carry out the normal processing shown in FIG.

  In the gaming machine main part updating process, the detection state information of the first counter circuit 320 grasped by the signal reading process is different from the detection state information stored in the gaming machine main part storage area 313a of the RAM 313. In this case, the detection status information is updated.

  As for the gaming machine main part update process, as shown in the flowchart of FIG. 29, a comparison process is first executed in step S701. In the comparison process, the detection state information stored in the register of the CPU 310 in the signal reading process is compared with the detection state information stored in the gaming machine main part storage area 313a of the RAM 313. In a succeeding step S702, it is determined whether or not the detection states compared in the comparison process match. As a result, if they match, the gaming machine main part update process is terminated as it is. On the other hand, if they do not match, after storing the latest detection state information, that is, the detection state information stored in the register of the CPU 310 in the storage area 313a for the gaming machine, in step S703, The game machine main part update process is terminated.

  Returning to the description of the power interruption update process, after executing the gaming machine main part update process in step S602, the front door frame update process is executed in step S603. In the front door frame update process, when the detection state information of the second monitoring device 290 grasped by the signal reading process is different from the detection state information stored in the front door frame storage area 313b of the RAM 313. Update the detection status information. Since this specific processing content is the same as the gaming machine main part update processing, description thereof is omitted here. After executing the front door frame update process in step S603, the power interruption update process is terminated.

  By executing the power interruption update process as described above, the detection state information in each of the monitoring devices 250 and 290 at the time when the power of the pachinko machine 10 is shut down is reliably stored in the RAM 313.

  Next, processing executed in the main processing (FIG. 25) will be described.

  In the main process, the power recovery opening monitoring process in steps S314 to S318 is executed for each of the counter circuits 320 and 330.

  In the power recovery opening monitoring process, first, a detection state grasping process is executed in step S314. In the detection state grasping process, signals (electric signal patterns) output from the first counter circuit 320 and the second counter circuit 330 are read. Information of the read signal is stored and held in a register of the CPU 310. In this case, the CPU 310 is provided with at least a first register and a second register, signal information of the first counter circuit 320 is stored and held in the first register, and signal information of the second counter circuit 330 is stored in the first register. It is stored and held in two registers.

  In subsequent step S315, a comparison process is executed. In the comparison process, the detection state of the first counter circuit 320 stored in the register of the CPU 310 in the detection state grasping process is compared with the information on the detection state stored in the storage area 313a for the main part of the gaming machine in the RAM 313. . In the comparison process, the detection state information of the second counter circuit 330 stored in the register of the CPU 310 in the detection state grasping process and the detection state information stored in the front door frame storage area 313b of the RAM 313 Compare

  In the subsequent step S316, it is determined whether or not the detection states of the first counter circuit 320 compared in the comparison process match, and whether or not the detection states of the second counter circuit 330 match. To do. As a result, if both match, the interrupt permission is set in step S311, and the process proceeds to normal processing. If either one does not match, it means that the gaming machine main part 12 or the front door frame 14 is opened and closed during power-off, and the process proceeds to step S317.

  In step S317, a power recovery notification process is executed. In the power recovery notification process, a power recovery notification command is output to the sound lamp control device 143. Thereby, the output of the notification sound from the speaker unit 26, the lighting of the error display lamp unit 24, and the notification display on the symbol display device 91 are performed. However, these notification modes are different from the notification mode based on the normal-time notification command. In addition, the sound lamp control device 143 continues various notifications until a notification release operation such as the state return switch 245 is performed. That is, not only the notification mode but also the notification cancellation mode differs between the normal time and the power recovery time. However, the present invention is not limited to this, and the notification mode and the notification release mode may be the same during normal operation and during power recovery.

  In the power recovery notification process, a power recovery notification signal is output to the hall computer provided in the game hall via the external terminal board 213. In this case, the hall computer is intended for processing of storing identification information such as the date and time when the power recovery notification signal is input from the pachinko machine 10 and the machine number of the pachinko machine 10 as a history, and the monitoring camera provided in the game hall. Processing such as turning to the pachinko machine 10 is executed.

  If the game machine main part 12 or the front door frame 14 is operated to be opened or closed while the power is cut off by performing the power recovery notification process, the game hall manager or the like is notified. If it is an unauthorized operation, it can be dealt with.

  In the power recovery notification process, when the gaming machine main part 12 is opened / closed and when the front door frame 14 is opened / closed, a power failure notification command or a power failure detection signal is detected. The information form may be different. In this case, the notification mode may be different in the pachinko machine 10 itself or in the hall computer depending on whether the front door frame 14 is opened or closed while the power is shut off and when the gaming machine main part 12 is opened or closed while the power is shut off. It is possible to appropriately deal with the game hall manager or the like. In addition, the power recovery notification process is not limited to the above, and only one of the power recovery notification command and the power recovery notification signal may be output. Further, as a process based on the output of the power recovery notification command, only a part of the notification sound output from the speaker unit 26, the error display lamp unit 24 lighting, or the notification display on the symbol display device 91 is executed. It is good also as a structure.

  After performing the power recovery notification process in step S317, the process proceeds to step S318. In step S318, the detection state information determined not to match in step S316 among the detection state information of the counter circuits 320 and 330 stored in the register of the CPU 310 in step S314 is stored in the corresponding storage area 313a. , 313b. Thereafter, interrupt permission is set in step S311, and the process proceeds to normal processing.

  According to the first embodiment described in detail above, the following excellent effects are obtained.

  The opening of the gaming machine main part 12 and the front door frame 14 can be monitored in a state where the power supply is cut off. Thereby, the fraud with respect to the pachinko machine 10 can be suitably suppressed while contributing to energy saving (power saving).

  Moreover, it was set as the structure by which the opening / closing detection of the game machine main part 12 and the front door frame 14 is performed separately independently. For this reason, the object by which opening / closing was performed among the gaming machine main part 12 and the front door frame 14 can be specified. Therefore, it is possible to easily identify the location that is the target of fraud in the pachinko machine 10.

  As shown in FIG. 19 and the like, the relative position between the coil 271 and the magnetic body 261 is displaced by the metal fitting 185 that is triggered by the closing operation of the gaming machine main part 12 (trigger). Thereby, the electromotive force dispersion | variation resulting from the dispersion | variation in the closing speed of the game machine main part 12 can be suppressed, and it is possible to improve the opening / closing detection precision of an opening-closing body. When the closing operation itself of the gaming machine main part 12 is used to realize the displacement of the relative position between the conductor and the magnetic body, the closing speed of the gaming machine main part 12 is directly related to the magnitude of the electromotive force. Will have a positive influence. That is, if the closing speed of the gaming machine main part 12 is low, there is a possibility that sufficient electromotive force is not generated. For this reason, for example, when the gaming machine main part 12 is slowly opened and closed by a cheating person, there is a possibility that the cheating is not found. However, as described above, by using the opening / closing operation of the gaming machine main part 12 as an opportunity for generating electromotive force, it is possible to secure the electromotive force regardless of the opening / closing speed of the gaming machine main part 12. Is possible. Thereby, it is possible to contribute to the improvement of crime prevention. Note that the same effect can be expected for opening / closing detection of the front door frame 14.

  Further, as shown in FIG. 9 and the like, the monitoring devices 250 and 290 are attached to the locking device 170 to integrate them. For this reason, compared with the case where the monitoring apparatus 250,290 and the locking apparatus 170 are assembled | attached separately, both position dispersion | variation can be suppressed suitably. Furthermore, the monitoring devices 250 and 290 are fixedly arranged in the space for securing the operation gap of the locking device 170, so that the space around the locking device 170 is effectively utilized while ensuring the operation of the locking device 170. Furthermore, by arranging the devices to be confirmed at the time of maintenance or the like, it contributes to the efficiency of the confirmation work.

  The magnetic units 260 and 292 and the conductor units 270 and 294 are unitized as monitoring devices 250 and 290, and are configured separately from the metal fitting 185 as a movable part. And in the state which the operation part 186a of the metal fitting 185 contact | abutted with respect to the contact part 264 of the 1st monitoring apparatus 250, both are displaced in connection and the induced electromotive force generate | occur | produces in the monitoring apparatus 250,290. It was. The metal fitting 185 or the like is a part that operates when the gaming machine main part 12 or the like is locked, and is considered to have a rattling to allow variation in the position of the gaming machine main part 12 or the like. For this reason, it is assumed that position variations in directions other than the preset operation direction are likely to occur. As described above, the monitoring devices 250 and 290 and the metal fitting 185 are separated from each other, and the operation portion 186a and the contact portion 264 can come into contact with each other within a predetermined range. The portion 186a, the contact portion 264 and the contact position are allowed to be displaced. As a result, it is possible to suppress the inconvenience that the positional deviation between the magnetic units 260 and 292 and the conductor units 270 and 294 is induced due to the position variation of the metal fitting 185 and the like. If, for example, the metal fitting 185 or the like is made of a magnetic material, or a magnetic material is fixed to the metal fitting 185 or the like, the interference between the magnetic body and the conductor is avoided in consideration of the positional variation of the metal fitting 185. It is necessary to set the clearance. In such a case, it is difficult not only to increase the induced electromotive force generated by the change in the relative position between the magnetic body and the conductor, but also the variation in induced electromotive force tends to occur. However, as described above, the monitoring devices 250 and 290 are unitized to suppress variations in the relative positions of the magnetic units 260 and 292 and the conductor units 270 and 294 and to stably obtain a large electromotive force. It has become.

  The opening / closing detection of the gaming machine main part 12 is performed when the gaming machine main part 12 is closed. For this reason, the inconvenience that the opening / closing detection result is tampered with is not likely to occur, and a more preferable fraud suppression effect can be expected. More specific description will be given below. If the configuration is such that opening / closing detection is performed when the gaming machine main part 12 is opened, since the gaming machine main part 12 is opened, unauthorized access to the counter circuit 320 or the like in which the opening / closing detection information is stored. May occur. In such a case, the injustice may cause the inconvenience that the opening history of the opening / closing body is deleted. If the release history is erased in this way, there is a concern that it will be difficult to find fraud. However, as described above, when the gaming machine main part 12 is closed, the opening / closing detection is performed when the gaming machine main part 12 is closed. For this reason, access to the first monitoring device 250 and the main control device 162 becomes difficult, and it becomes difficult to falsify the open / close detection history. Therefore, it can contribute to the security of the opening / closing detection function.

  As shown in FIG. 3 and the like, the monitoring devices 250 and 290 are arranged in the gaming machine main part 12. The gaming machine main part 12 is provided with a main control device 162, a power supply device 243, and the like. By arranging the main control device 162 and the control device 162 on the same mounting object, it contributes to simplification of wiring and the like. . In particular, in the present embodiment, the gaming machine main part 12 and the front door frame 14 can be opened and closed independently, and the monitoring devices 250 and 290 are arranged in the gaming machine main part 12 as described above. The independent opening / closing function of the gaming machine main part 12 and the front door frame 14 is easily secured.

  When the gaming machine main part 12 is closed, after the rotation angle of the gaming machine main part 12 reaches a predetermined range, the state where the visual recognition of the locking device 170 is prevented by the outer peripheral surface of the outer frame 11 is maintained. The That is, at the timing when the hook metal 185 contacts the hook receiving member 180, access to the hook metal 185 and the hook receiving member 180 from the outside of the pachinko machine 10 is restricted. For this reason, it is difficult to insert an unauthorized tool from the boundary portion between the gaming machine main part 12 and the outer frame 11 and to try to prevent the movement of the metal fitting 185 by the unauthorized tool. Therefore, it is possible to make an illegal act of obstructing the output of the signal by electromagnetic induction difficult by intentionally preventing the movement of the metal fitting 185.

  Further, when the front door frame 14 is closed with respect to the main body frame 13, the collar portion 65 is inserted into the insertion hole 74 of the main body frame 13, and the locking device 170 provided on the back side of the main body frame 13 is locked. The configuration is shifted to the state. Since the locking device 170 (more specifically, the hook receiving member 180) provided so as to be movable with respect to the hook portion 65 is covered with the main body frame 13, the movement of the hook receiving member 180 is hindered by an unauthorized tool or the like. It has become difficult. Therefore, it is possible to make an illegal act such as obstructing the output of the signal due to electromagnetic induction by intentionally hindering the movement of the collar receiving member 180.

  Further, when the gaming machine main part 12 is closed, after the rotation angle of the gaming machine main part 12 reaches a predetermined range, the outer peripheral surface of the outer frame 11 causes the gaming machine main part 12 and the outer frame 11 to be closed. Inconveniences such as access to the main control device 162 (specifically, the counter circuits 320 and 330) serving as storage means are suppressed through the boundary portion. Thereby, the inconvenience that an unauthorized tool or the like is inserted through the boundary portion and the memory is falsified can be suitably suppressed. In the present embodiment, in particular, the notification of opening detection is terminated by the switching operation of the power switch 229a (power ON → power OFF). That is, when the power switch 229a is switched by an unauthorized tool, the opening / closing detection result can be concealed. In this regard, in the state where the opening / closing detection is performed and the result is stored, the entry of unauthorized tools or the like is suppressed by the outer peripheral surface of the outer frame 11, so that it is preferable to conceal the detection result by the unauthorized operation of the power switch 229a. Can be suppressed.

  Opening / closing detection is performed when the gaming machine main part 12 and the front door frame 14 have reached the closed position, and accordingly, the gaming machine main part 12 and the like are shifted to the locked state by the locking device 170. For this reason, the act of reopening the gaming machine main part 12 or the like in order to conceal the opening / closing detection result involves releasing the locking state of the locking device 170. Thereby, the preliminary act of falsifying the detection result can be made difficult. Therefore, it is difficult to perform fraudulent acts, and it can contribute to the improvement of crime prevention.

  Further, in the present embodiment, it is assumed that not only the main controller 162 but also the game board 81 (specifically, the game area) is likely to be fraudulent. Even if the front door frame 14 is opened and the game board 81 is cheated, it is possible to grasp the cheating by detecting the opening and closing of the front door frame 14. Thus, when the front door frame 14 is opened, access to the main control device 162 (specifically, each counter circuit 330) and the power switch 229a is hindered by the main body frame 13 and the like. Thereby, falsification of a detection result etc. are controlled suitably. Even if the gaming machine main part 12 is additionally opened or closed to tamper with the opening / closing detection result of the front door frame 14, the opening / closing of the gaming machine main part 12 is monitored by the first monitoring device 250. For this reason, even if the opening / closing detection result of the front door frame 14 is falsified, at least the opening / closing detection result of the gaming machine main part 12 is stored and stored. Therefore, it can be suggested that the opening / closing of the front door frame 14 may have been performed based on the opening / closing detection result of the gaming machine main part 12.

  If the gaming machine is fraudulent when the power is turned off at night or the like, it is considered that the fraudulent person is required to take immediate action while being wary of fraud detection by another security system such as a security camera. In such a case, it is assumed that the gaming machine main part 12 and the front door frame 14 are immediately closed after the gaming machine main part 12 and the front door frame 14 are opened, and the work is finished. . Inviting or conspicuous time loss is likely to be a cause of fraud, and for example, it is unlikely that the gaming machine main part 12 and the front door frame 14 are opened multiple times.

  In the present embodiment, each counter circuit 320, 330 is provided with two T flip-flops 321 and the like, and detection is possible when the gaming machine main part 12 and the front door frame 14 are opened a number of times excluding multiples of 4. did. Specifically, a configuration is adopted in which detection at 4 degrees is set as one cycle and the original detection state is restored. As described above, it is considered that the number of times that the gaming machine main part 12 and the like are opened when the power is turned off is approximately one degree. Based on this, the counter circuits 320 and 330 can detect the opening of at least three degrees, thereby ensuring the unauthorized opening / closing detection function while simplifying the configuration. As shown in FIG. 22, not only the closing operation of the gaming machine main part 12 and the like but also a positive voltage is generated with the opening operation. Even if those positive voltages indicate values exceeding the threshold value, and even if the counter circuits 320 and 330 count open, the open / close detection can be performed up to three times. It is suppressed. Incidentally, it is possible to lengthen the detection cycle (specifically, increase the number of detections) by increasing the number of T flip-flops 321 and the like. Specifically, the number of detections constituting one cycle is expressed by N to the power of 2 where N is the number of T flip-flops. Therefore, by increasing the number of N, the length of one cycle is restored to the original detection state. The length may be difficult to substantially return. Thus, by lengthening one cycle, it becomes difficult to conceal the fact of opening and closing, and the reliability of the opening and closing detection function can be improved.

  In each counter circuit 320, 330, the number of times the gaming machine main part 12 is opened is counted based on the operation of the locking device 170 to the locking position of the bar bracket 185 and the like. Therefore, in order to change the detection state of the counter circuits 320 and 330 and conceal the opening / closing fact, it is necessary to release the locked state after the gaming machine main part 12 is locked. As described above, performing the unlocking operation every time the detection state of the counter circuits 320 and 330 is changed takes time and increases the possibility of detecting fraud. Therefore, by repeatedly opening and closing the gaming machine main part 12 and the like, it becomes difficult to conceal the illegal opening and closing fact, which can contribute to the improvement of crime prevention of the gaming machine.

  The counter circuit 320, 330 is configured to detect opening / closing by inputting a positive voltage generated in each of the monitoring devices 250, 290. This plus voltage is generated based on the opening and closing operations of the gaming machine main unit 12 and the like. As described above, the positive voltage generated with the closing operation is set so as to exceed the threshold value in the counter circuits 320 and 330. For this reason, reliable opening / closing detection is performed during the closing operation. On the other hand, a configuration is adopted in which the magnitude of the positive voltage changes in accordance with the rotation speed of the gaming machine main part 12 and the like during the opening operation. For this reason, it is easy to produce the dispersion | variation whether the opening / closing detection is performed whenever it opens. Therefore, by repeatedly opening and closing the gaming machine main part 12 and the like, an illegal concealing action such as returning the counter state to the state before the illegality becomes difficult. If the gaming machine main part 12 or the like is opened slowly to avoid opening / closing detection during the opening operation, it takes time to open and close the gaming machine main part 12 or the like. As a result, since the possibility of fraud detection increases, it is possible to suitably suppress taking measures such as slowly opening the gaming machine main part 12 and the like.

(Second Embodiment)
In the present embodiment, the configuration relating to holding of opening / closing records of the gaming machine main part 12 and the front door frame 14 based on signals from the monitoring devices 250 and 290 is different from that in the first embodiment. Therefore, the configuration will be described in detail below. In the following description, differences from the first embodiment will be mainly described, and description of the same configuration will be basically omitted. FIG. 30 is a block circuit diagram in the present embodiment.

  As shown in FIG. 30, in the present embodiment, a main control device 162, a power supply device 243, a relay board 300, and the monitoring devices 250 and 290 are provided as in the first embodiment. Each monitoring device 250, 290 has magnetic bodies 261, 293 and coils 271, 295. Since the configuration relating to the connection between the coils 271 and 295 and the relay substrate 300 is the same as that in the first embodiment, the description thereof is omitted. The same applies to the connection between the relay board 300 and the main controller 162.

  Here, in the present embodiment, a first record holding circuit 350 is provided instead of the first counter circuit 320, and a second record holding circuit 360 is provided instead of the second counter circuit 330. Since both the record holding circuits 350 and 360 have the same configuration, the first record holding circuit 350 will be described in detail first, and the second record holding circuit will be briefly described later.

  The power supply unit 314a of the power supply device 243 and the main control board 301 are connected by a power supply line ELN1. The power supplied via the power line ELN1 is divided into power directed to the CPU and power directed to the first record holding circuit 350 in the main control board 301. The power line branched toward the first record holding circuit 350 is provided with a delay switch 351. When this delay switch 351 is turned on, power can be supplied to the first record holding circuit 350, and the power switch is turned off. As a result, the power supply is cut off. The electric power supplied to the first record holding circuit 350 is rectified via the diode 352 and can flow into the source capacitor 353 and the source side of the MOSFET 354. The diode 352 is connected to the source capacitor 353 so as to be reverse-biased.

  The source capacitor 353 is grounded, and is configured to be charged when the pachinko machine 10 is powered on. A signal from the signal line LN 2, that is, a signal from the first monitoring device 250 is input to the gate terminal of the MOSFET 354 via the diode 355. The MOSFET 354 is of a type in which current flows between the source and drain when the input voltage of the gate terminal 354a is at the HI level, and current does not flow through the source and drain when it is at the LOW level. That is, the current flow is adjusted by a signal (specifically, a positive voltage) from the first monitoring device 250. A drain capacitor 356 having a capacity substantially equal to that of the source capacitor 353 is connected to the drain side of the MOSFET 354, and this drain capacitor 356 is grounded. A lead wire having a pull-up resistor 357 is connected between the drain capacitor 356 and the MOSFET 354, and one end of the lead wire is connected between the diode 355 and the gate terminal of the MOSFET 354. A main switch 358 as a delay means is provided between the lead wire and the gate terminal. When the main switch 358 is ON, the signal can reach the gate terminal of the MOSFET 354, and when it is OFF, the signal is blocked from reaching. Further, the drain capacitor 356 is connected to the input port of the CPU 310, and it is possible to determine whether or not electric power is stored in the drain capacitor 356 by the CPU 310. Further, a discharge switch 359 whose opening / closing of the circuit is controlled by the CPU 310 is connected to the drain capacitor 356. The discharge switch 359 is grounded, and the charge stored in the drain capacitor 356 is discharged (discharged) when the circuit is shifted to a closed state.

  In the first embodiment, power is supplied to the T flip-flop 321 or the like from the capacitor 324 or the like to save the open / close record, but in the present embodiment, the storage state of the drain capacitor 356 is stored. The configuration is such that the opening / closing record is preserved by the change itself. Hereinafter, the operation of the first record holding circuit 350 described above will be described in detail.

  When the power of the pachinko machine 10 is ON, power is supplied from the power supply device 243 to the source capacitor 353, and the source capacitor 353 is charged. When the power of the pachinko machine 10 is OFF, the source capacitor 353 is charged and the drain capacitor 356 is empty. In this state, when the gaming machine main part 12 is opened and then closed, a signal is output from the first monitoring device 250. The output signal is rectified by the diode 355 and reaches the gate terminal of the MOSFET 354. As a result, the voltage at the gate terminal 354 a becomes HI level, whereby the source capacitor 353 is discharged, and the discharged electricity flows into the drain capacitor 356 via the MOSFET 354. In this case, part of the current is guided to the gate terminal 354a of the MOSFET 354 by the pull-up resistor 357, and the voltage at the gate terminal 354a of the MOSFET 354 is maintained at the HI level. Thereby, the movement of electricity from the source capacitor 353 to the drain capacitor 356 is continued. In the state where the exchange of electricity between the two capacitors 353 and 356 is completed, the source capacitor 353 is almost empty and the drain capacitor 356 is almost full. The drain capacitor 356 is electrically connected to the input port of the CPU 310, and the voltage of the drain capacitor 356 detected by the CPU 310 is displaced (increased).

  Next, differences between the respective control processes executed by the CPU 310 of the main controller 162 will be described with reference to the flowcharts of FIGS. FIG. 31 and FIG. 32 show the main process at power-on, and FIG. 33 shows the process at power interruption.

  As shown in FIGS. 31 and 32, in the main process, after the detection state is updated in step S318, an OFF signal of the main switch 358 is output in step S319. As a result, the main switch 358 is opened, and the signal to the gate terminal 354a of the MOSFET 354 is cut off. That is, the current flow in the MOSFET 354 is cut off. Next, in step S320, an ON signal of the discharge switch 359 is output. When the charge is stored in the drain capacitor 356, the charge is discharged. Next, an ON signal of the delay switch 351 is output in step S321. Thereby, accumulation of electric charges in the source capacitor 353 is started.

  Next, the difference in the power interruption process will be described. As shown in FIG. 33, at the time of power interruption, after the main body frame update process is performed in step S603, an OFF signal of the delay switch 351 is output in step S604. As a result, the first record holding circuit 350 is disconnected from the power supply line. Next, an OFF signal of the discharge switch 359 is output in step S605. Thereby, the discharge of the drain capacitor 356 is suppressed, and the state is reached. After the OFF signals of the two switches 351 and 359 are output in this way, the ON signal of the main switch 358 is output in step S606. When the main switch 358 is turned on, input of a signal to the gate terminal 354a of the MOSFET 354 is permitted. Therefore, the first record holding circuit 350 is activated. Note that each of the switches 351, 358, and 359 may be formed of a transistor such as an FET.

  The second record holding circuit 360 has the same configuration as the first record holding circuit 350. Specifically, the second record holding circuit 360 is arranged in parallel with the first record holding circuit 350 and is configured to receive a signal from the second monitoring device 290. Similarly to the first record holding circuit 350, the second record holding circuit 360 includes a source capacitor 363, a drain capacitor 366, a MOSFET 364, a pull-up resistor 367, and various switches 361, 368, and 369. With these configurations, it is possible to grasp the fact of opening and closing the front door frame 14 in a state where power supply is interrupted at night and the like. Note that each of the switches 361, 368, and 369 may be formed of a transistor such as an FET, similarly to the switch 351 and the like.

  According to the second embodiment described in detail above, the following excellent effects can be obtained.

  By providing the record holding circuits 350 and 360, the fact that the gaming machine main part 12 and the front door frame 14 are opened and closed in a state where power supply is interrupted at night or the like can be grasped. Thereby, it can contribute to suppression of fraud, aiming at power saving.

  The game machine main part 12 and the front door frame 14 are closed, and the charge is transferred. In other words, charges are accumulated in the drain capacitor 356 using the closing operation of the gaming machine main body 12 and the front door frame 14 as a trigger. For this reason, when the gaming machine main part 12 and the front door frame 14 are opened, the record holding circuits 350 and 360 do not operate. Even if the fraudulent person tries to forcibly discharge the charge stored in the drain capacitor 356, it is a pre-stage where the charge is transferred when the gaming machine main part 12 and the front door frame 14 are opened. Such illegal discharge cannot be performed. Therefore, the configuration is such that it is easy to avoid unauthorized erasure of the opening / closing detection record (that is, concealment of fraud). Note that the CPU 310 may be configured to confirm the charge amount of the source capacitor 353 in addition to the drain capacitor 356. As a result, it is possible to grasp the fact that the supply of charge to the drain capacitor 356 is hindered when the charge stored in the source capacitor 353 is illegally discharged.

  Usually, when the power of the pachinko machine 10 is turned on again, charge is supplied to and discharged from the capacitors 353, 363, 356, and 366. That is, the opening record of the gaming machine main part 12 and the front door frame 14 is erased. Even if a fraudster turns off the power after the pachinko machine 10 is turned on in order to conceal his own fraud, the main part of the gaming machine is again to complete the fraud concealment. 12 and the front door frame 14 need to be closed. In this way, the act of closing the gaming machine main part 12 and the front door frame 14 again is newly stored by the record holding circuits 350 and 360, so that it is possible to avoid such concealment of illegal acts. .

  The configuration is such that the transfer of charge between the source capacitors 353 and 363 and the drain capacitors 356 and 366 is started by the trigger of the signal from each of the monitoring devices 250 and 290 reaching the gate terminal of the MOSFET 354. In other words, even when the signals from the monitoring devices 250 and 290 are instantaneous and are not continuously held, the charge transfer between the capacitors 353, 363, 356, and 366 is continued. This eliminates the need for a configuration for holding the signals at the HI level in each of the monitoring devices 250 and 290, thereby making it possible to avoid complication of the configuration.

  In the present embodiment, the opening is detected by a change in the capacitance of the capacitor 356 or the like. No matter how many times the opening / closing detection of the gaming machine main unit 12 or the like is performed when the power is turned off, the capacity of the capacitor 356 or the like does not return to the state before the opening / closing detection. This ensures reliable opening / closing detection regardless of the number of times of opening / closing detection. In other words, the inconvenience that the opening cannot be detected depending on the number of opening and closing of the gaming machine main part 12 or the like is avoided. As a result, the reliability of the open / close detection function is improved. Further, by eliminating the difference due to the number of times of opening / closing detection and storing only the fact that the detection of opening has been performed, the configuration related to counting the number of times of opening becomes unnecessary. For this reason, the configuration of the memory holding circuit can be contributed to simplification.

(Third embodiment)
In the second embodiment, the first record holding circuit 350 and the second record holding circuit 360 are used to grasp the fact that the main part 12 of the gaming machine and the front door frame 14 are opened and closed. In the embodiment, this configuration is simplified. Therefore, the details of each of the record holding circuits 400 and 410 will be described below with reference to FIG. FIG. 34 is a block diagram showing each record holding circuit 400, 410 in the present embodiment.

  As shown in FIG. 34, compared with the second embodiment, drain capacitors 356 and 366 and discharge switches 359 and 369 are omitted. Further, signal lines LN5 and LN6 extending from the source capacitors 353 and 363 are connected to the input port of the CPU 310, and it is possible to detect whether or not charges are stored in the source capacitors 353 and 363. .

  In such a configuration, movement of current in the MOSFETs 354 and 364 is allowed by closing the gaming machine main part 12 and the front door frame 14 in a state where the power supply is cut off. As a result, the charges of the source capacitors 353 and 363 are discharged.

  Next, differences between the respective control processes executed by the CPU 310 of the main controller 162 will be described with reference to the flowcharts of FIGS. As described above, since the discharge switches 359 and 369 are omitted, various processes associated therewith can also be omitted. Specifically, a process is set in which step S320 in FIG. 32 and step S605 in FIG. 33 are omitted. Further, in the detection state grasping process in S314, the charge amount of the source capacitors 353 and 363 is confirmed. In S315 and S316, it is determined whether or not the electric charge that is charged when the power is turned off and is almost full is changed when the power is turned on. Specifically, it is determined whether or not a threshold value set by subtracting a natural discharge amount assumed in advance from a charge amount when the power is turned off is approximately equal to a charge amount when the power is turned on. Note that, as described above, the configuration for comparing whether the threshold value and the charge amount at the time of power-on is the same is changed to determine whether the charge amount at the time of power-on is lower than the threshold value. It is also possible. In addition, the charge amount at the time of turning off the power supply is not compared, and the determination is made based on whether or not the charge amount at the time of turning on the power is below a set reference value regardless of the charge amount at the time of turning off the power supply. It is also possible. In such a case, S601 to S603 in the power interruption updating process shown in FIG. 33 can be omitted.

  According to the third embodiment described in detail above, the following excellent effects are produced.

  A configuration in which the fact that the gaming machine main part 12 and the front door frame 14 are opened and closed is stored by discharging the electric charge stored in the source capacitors 353 and 363 is used. When a fraudster tries to erase the opening / closing record of the main part 12 of the gaming machine or the front door frame 14, the charge needs to be reapplied after the charges of the source capacitors 353 and 363 are discharged. Compared to the act of discharging, the act of charging charge is considered more difficult. For this reason, it is thought that it can contribute to the further improvement of crime prevention. In addition, since the act of charging the charge needs to be performed with the gaming machine main part 12 and the front door frame 14 being closed, an illegal concealment work can be made more difficult.

  In addition, if the configuration is such that the opening / closing of the opening / closing body is detected by increasing the charge amount of the source capacitors 353, 363, the opening / closing detection is difficult because the charges of the source capacitors 353, 363 decrease due to natural discharge or the like. There is a possibility that Specifically, if the amount of charge has been reduced based on the operation of the gaming machine main unit 12 and the like, and the amount of charge has decreased to the same level as before storage due to spontaneous discharge, etc., it is mistaken that the amount of charge has not changed. There is a possibility that. In such a case, there is a possibility that the fact that the game machine main part 12 or the like has been opened or closed cannot be grasped. On the other hand, as shown in the present embodiment, when the opening / closing of the gaming machine main part 12 and the like is detected by reducing the charge amount of the source capacitors 353 and 363, the charge amount is less than a predetermined amount due to natural discharge or the like. Even if it is reduced to, the difference between the original charge amount occurs. For this reason, it is possible to easily grasp the change in the charge amount. In such a case, it is difficult to specify whether or not the cause of the change in the charge amount is due to the opening / closing of the gaming machine main part 12 etc., but at least the gaming machine main part 12 etc. may have been opened / closed. It is possible to call attention to fraud. Thereby, the oversight of fraud with respect to the pachinko machine 10 can be suppressed.

  As described above, the drain capacitor 356 and the like are omitted, and the function of grasping the fact of opening and closing of the gaming machine main part 12 and the front door frame 14 can be ensured while contributing to simplification of the configuration.

(Fourth embodiment)
In the first to third embodiments, the main control board 301 has a configuration for recording and storing the fact that the gaming machine main part 12 and the front door frame 14 are opened and closed. In the present embodiment, each of these components is configured to be mounted on each monitoring device. Therefore, the configuration will be described in detail below. In the following description, differences from the first embodiment will be mainly described, and description of the same configuration will be basically omitted. FIG. 35 is a block circuit diagram in the present embodiment.

  As shown in FIG. 35, in the present embodiment, as in the first embodiment, a main control device 162, a power supply device 243, a relay board 300, and the monitoring devices 420 and 430 are provided. Each monitoring device 420, 430 has magnetic bodies 261, 293 and coils 271, 295. Details of these components are the same as those in the first embodiment, and thus description thereof is omitted.

  In the present embodiment, the first monitoring board 421 is mounted on the first monitoring apparatus 420, and the second monitoring board 431 is mounted on the second monitoring apparatus 430. Since each of these monitoring boards 421 and 431 has the same configuration, only the first monitoring board 421 will be described here.

  The first monitor board 421 is provided with a first record holding circuit 422 having the same configuration as the record holding circuit 400 described in the third embodiment. One end of the coil 271 is fixed to the first monitoring board 421 by fixing means such as solder. A signal line LN1 for transmitting a signal to the relay board 300 is attached to the first monitoring board 421. Specifically, the signal line LN1 is detachably connected to a connector CN1 provided on the first monitoring board 421 and a connector CN2 provided on the relay board 300.

  The relay board 300 is connected to the main control board 301 via the harness H (specifically, the signal line LN2). Specifically, the harness H is detachably connected to a connector CN3 provided on the relay board 300 and a connector CN4 provided on the main control board 301.

  Inside the main control board 301, the power supplied from the power supply device 243 is divided. The divided power is supplied to the CPU and the relay board 300. A delay switch 351 that allows or cuts off the flow of current is provided in the power transmission path toward the relay board 300. A current flow is allowed when the delay switch 351 is ON, and a current flow is blocked when the delay switch 351 is OFF. A power supply line ELN2 constituting the harness H is connected between the connectors CN3 and CN4, and power supply to the relay board 300 is realized via the power supply line ELN2. A power supply line ELN3 is also connected between the connector CN2 of the relay board 300 and the connector CN1 of the first monitoring board 421, and power is supplied to the first monitoring device 250 via the power supply line ELN3. It has a configuration. That is, part of the power supplied from the power supply device 243 to the main control board 301 reaches the source capacitor of the first monitoring board 421 via the power supply line ELN2 → the relay board 300 → the power supply line ELN3. 353 is charged.

  In such a configuration, the storage state of the source capacitor 353 is output to the input port of the CPU 310 via the signal line LN1, the relay substrate 300, and the signal line LN2. The source capacitor 353 is in a state where electric charges are stored when power supply is cut off. When the gaming machine main part 12 is opened and closed when the power supply is cut off (specifically, it is closed), the charge of the source capacitor 353 is discharged. When the pachinko machine 10 is activated, it is possible to grasp the fact that the gaming machine main part 12 is opened and closed by detecting that no charge is stored in the source capacitor 353.

  Similarly, the second monitoring board 431 is connected to the relay board 300 via the signal line LN4 and the power supply line ELN4. In addition, it is connected to the main control board 301 through the signal line LN3 and the power supply line ELN2. Accordingly, the open / close detection signal output from the second record holding circuit 432 is input to the CPU 310. Since the operation of the second monitoring board 431 is the same as that of the first monitoring board 421, the description thereof is omitted.

  Note that each control process executed by the CPU 310 of the main control device 162 is the same as that in the third embodiment, and a description thereof will be omitted.

  According to the fourth embodiment described in detail above, the following excellent effects are achieved.

  It is possible to suppress fraud such as blocking the transmission of signals from the monitoring device to the record holding circuit (specifically, the MOSFET). If the signal from the monitoring device does not reach the MOSFET, the operation of the record holding circuit may not be performed normally. In the present embodiment, since the record holding circuits 422 and 432 (monitoring boards 421 and 431) are arranged in the monitoring devices 420 and 430, it is possible to make the illegal acts as described above difficult. That is, even if an illegal act such as removing the signal lines LN1 and LN3 connecting the monitoring devices 420 and 430 and the relay board 300 or removing the harness H connecting the relay board 300 and the main control board 301 is performed. Thus, it is possible to avoid the influence on the record holding circuits 422 and 432 itself. That is, even if the gaming machine main part 12 is opened and closed with the signal line LN1 and the like removed, it can be recorded.

  Moreover, it is conceivable that the signal transmission to the input port of the CPU 310 is hindered by removing the signal line LN1 and the like as described above. In the present embodiment, opening / closing of the gaming machine main part 12 and the like is detected by the CPU 310 based on the charges of the source capacitors 353 and 363. Specifically, the determination is made based on whether or not the electric charges stored in the source capacitors 353 and 363 remain when the power of the pachinko machine 10 is turned off. When the signal to the CPU 310 is interrupted due to the removal of the signal line LN1 or the like, it is considered that the electric charges of the source capacitors 353 and 363 are lost. Thereby, it is possible to indirectly grasp the fact that the gaming machine main part 12 and the like have been opened and closed. Therefore, it is possible to avoid the inconvenience that the opening / closing detection function is impaired due to the removal of the signal line LN1, etc., and to contribute to further improvement of crime prevention.

(Other embodiments)
In addition, it is not limited to the description content of embodiment mentioned above, For example, you may implement as follows.

  (A) In each of the above embodiments, the opening / closing detection information of the gaming machine main part 12 and the front door frame 14 is stored inside the pachinko machine 10, and the gaming machine owner is processed by the CPU 310 based on the stored information. It is configured to determine whether or not the part 12 etc. has been opened or closed, but this is changed, and the stored information is output to the hall computer via the external terminal board 213, and the main part of the gaming machine is It may be configured to determine whether or not 12 or the like has been opened or closed.

  (B) In each of the above-described embodiments, a reliable opening / closing detection is performed when the gaming machine main part 12 and the front door frame 14 are closed, and a variation in whether opening / closing is detected when the gaming machine main part 12 and the front door frame 14 are opened may occur. However, it may be configured to reliably detect opening and closing both when the gaming machine main part 12 and the front door frame 14 are opened and closed.

  Although not described in each of the above-described embodiments, the power supply opening / closing detection means for detecting the opening / closing of the gaming machine main part 12 and the front door frame 14 in a state where power is supplied. It is also possible. As a result, further improvement in crime prevention can be expected.

  (C) In each of the above embodiments, the locking device 170 is configured to simultaneously perform the transition of the gaming machine main part 12 to the locked state and the opening / closing detection of the gaming machine main part 12 and the front door frame 14. However, the present invention is not necessarily limited to this, and both may be implemented at different timings. For example, by providing an operation mechanism that operates independently of the locking device, the timing of the transition to the locked state of the gaming machine main part 12 by the locking device 170 and the opening / closing detection of the gaming machine main part 12 or the front door frame 14 It is also possible to shift.

  More specifically, the hook metal 185 and the hook receiving member 180 of the locking device 170 are used as the “movable part”. However, the present invention is not limited to this and may be changed as follows. That is, an operation mechanism that operates using the operation of the gaming machine main part 12 and the front door frame 14 as a trigger may be provided separately. For example, the operating mechanism includes a moving body that reciprocates in a predetermined direction, an urging member (such as a spring or rubber) that urges the moving body in the moving direction, and a restriction unit that restricts the position of the moving body. It may be configured. The moving body is set so as to be movable between two positions: an initial position arranged against the urging force of the urging member and an operating position moved by the urging force of the urging member. The restricting unit includes an allowable position that allows movement of the moving body when the gaming machine main part 12 is closed, and a restriction position that restricts movement of the moving object when the gaming machine main part 12 is opened. Provide switchable. The gaming machine main part 12 is provided with an operation part for operating the restriction part, and the restriction part is switched to the allowable position when the operation part hits the restriction part. The operation unit and the regulation unit may be configured to be hit when the gaming machine main part is closed. Further, the gaming machine main part 12 is provided with a moving body guide part that moves the moving body against the urging force of the urging member, and the moving body is guided to the initial position as the gaming machine main part 12 is opened. The configuration. In such a case, the restricting portion is switched to the restricting position when the operating portion is separated from the restricting portion. As a result, the moving body is held at the initial position. Thus, by providing an operation mechanism independently of the locking device, the transition to the locked state of the gaming machine main part 12 by the locking device 170 and the opening / closing detection of the gaming machine main part 12 and the front door frame 14 are different. It becomes possible to implement at the timing. The above-described configuration can be applied to the front door frame 14.

  (D) In each of the above embodiments, the gaming machine main part 12 as the “opening / closing body (first opening / closing body)” is configured to open and close by rotating with respect to the “support target” outer frame 11. The gaming machine main part 12 may be configured to open and close by parallel movement with respect to the outer frame 11. For example, the gaming machine main part 12 may be configured to be in a closed state with respect to the outer frame 11 by sliding the game machine main part 12 toward the outer frame 11, that is, backward. Similarly, the front door frame 14 as the “opening / closing body (second opening / closing body)” is also opened / closed by parallel movement with respect to the gaming machine main part 12 as the “support target (first opening / closing body)”. It is good also as a structure.

  (E) In each of the above embodiments, the magnetic body 261 provided so as to move is moved with respect to the coil 271 as a fixed “conductor”, so that the relative position of both is displaced. It is also possible to change this as follows. That is, it is also possible to adopt a configuration in which the relative position of the two is displaced by moving the conductor provided so as to move with respect to the fixed magnetic body. However, when the conductor is configured to move, it is desirable to lengthen the wiring extending from the conductor in anticipation of the amount of movement of the conductor itself.

  Further, although a rod-shaped magnet is used as the “magnetic material”, the present invention is not limited to this. For example, it is possible to use a U-shaped magnet, and it is also possible to use two plate-like magnetic bodies arranged opposite to each other. Hereinafter, the latter will be specifically described among the above-described modifications. Instead of the magnetic body 261, an iron rod-like body is attached to the housing body 262. Then, instead of the conductor unit 270, opposing plate-like magnetic bodies are arranged in the housing 280. What is necessary is just to set it as the structure which electromagnetic induction generate | occur | produces, when the rod-shaped body provided in the movement passes between both magnetic bodies. In such a case, it is desirable to mount the rod-shaped body so as to face the direction orthogonal to the moving direction. Thereby, the range of the magnetic field area | region which a rod-shaped body passes can be expanded, and generation | occurrence | production of electromagnetic induction can be made easy.

  (F) In each of the above embodiments, in the pair of opening / closing mechanisms of the gaming machine main part 12 and the outer frame 11, the magnetic body 261 and the coil 271 as a “conductor” are arranged together on the gaming machine main part 12 side. However, this can be changed as follows. For example, both the magnetic body and the conductor can be disposed on the outer frame 11. In addition, one of the magnetic body and the conductor can be disposed in the gaming machine main portion 12 and the other can be disposed in the outer frame 11. In such a case, it is considered that the relative position between the magnetic body and the conductor is likely to vary due to the variation in the relative position between the gaming machine main part 12 and the outer frame 11. It is assumed that the magnitude of the induced electromotive force tends to vary due to such variation in relative position. Therefore, the magnetic body and the conductor are preferably arranged on the same target such as the gaming machine main part 12 and the outer frame 11.

  (G) In each of the above embodiments, the signals from the respective monitoring devices 250 and 290 are combined on the relay board 300. However, this may be changed as follows. That is, a separate relay board may be provided for each of the monitoring devices 250 and 290. In such a case, it is also possible to arrange a relay board inside the housings 280 and 291. Further, the relay substrate 300 can be omitted.

  (H) In each of the above embodiments, the electromotive force generation means uses an electromotive force generated by electromagnetic induction due to a change in the relative position between the magnetic body and the conductor. However, this is changed to a piezoelectric element (piezo element). It is also possible to use an electromotive force generated by applying pressure to the above.

  (I) In each of the above-described embodiments, the coil 271 and the coil spring 285 in each of the monitoring devices 250 and 290 are provided with separate and independent functions. However, both functions can be provided to one coil. For example, the coil 271 may be used as a spring. More specifically, the stopper 274 of the bobbin 272 may be eliminated and the one end of the coil 271 on the magnetic unit 260 side may be fixed to the housing 262. Thereby, the coil spring 285 can be deleted. However, in such a case, since the coil 271 expands and contracts with the movement of the magnetic body unit 260, there is a concern that the relative displacement speed of both becomes small. In such a case, electromagnetic induction may not be sufficiently performed. Therefore, it is considered desirable to employ a magnet having a strong magnetic force as the magnetic body 261 or increase the number of turns of the coil 271.

  (J) In the first embodiment, the counter circuits 320 and 330 corresponding to the gaming machine main part 12 and the front door frame 14 are individually provided, but this is changed to change the gaming machine main part 12 and the front door. It is also possible to provide one counter circuit that collectively counts the number of times the frame 14 is opened and closed. In such a case, the signal lines from both the monitoring devices 250 and 290 may be collected by the relay board 300 or the main control board 301, and the collected signals may be input to the integrated counter circuit. Thereby, it can contribute to simplification of a structure, ensuring the opening / closing detection function of the game machine main part 12 and the front door frame 14. FIG.

  Similarly, in the second and third embodiments, it is also possible to detect the opening and closing of the gaming machine main part 12 and the front door frame 14 with one record holding circuit by integrating the record holding circuits 350, 360, etc. It is. In such a case, it is difficult to determine whether one of the gaming machine main part 12 or the front door frame 14 has been opened or closed, but it can be suggested that at least fraud may have been performed.

  (K) In the first embodiment, the capacitor 324 as a power supply source for both the T flip-flops 321 and 322 is combined into one, but this is changed and the respective T flip-flops 321 and 322 are changed. A separate capacitor may be set for each. Similar changes can be made for the T flip-flops 331 and 332.

  (L) In the first embodiment, the first counter circuit 320 is configured by connecting two T flip-flops 321 and 322 in series. However, the number of T flip-flops is not limited to this. It is sufficient to provide at least a plurality. By increasing the number of T flip-flops, it is possible to increase the upper limit of the number of opening / closing detections in one cycle. Therefore, by repeatedly opening and closing the gaming machine main part 12 etc., the T flip-flops are returned to the state before the unauthorized opening / closing. Cheating can be difficult. Although it is possible to adopt a configuration in which only one T flip-flop is provided, in a configuration in which a positive voltage is generated based on both the opening operation and the closing operation, the T flip-flop is operated by a single opening / closing operation. There is a possibility that the status of the loop will switch for one cycle and return to the original status. For this reason, it is desirable to provide a plurality of T flip-flops.

  Note that other flip-flops such as a JK flip-flop and a D flip-flop may be used instead of the T flip-flop 321 or the like.

  (M) In the second embodiment, the CPU 310 checks only the power storage status of the drain capacitors 356 and 366. In addition to this, the CPU 310 checks the power storage status of the source capacitors 353 and 363. It is good also as composition to do. Thereby, further improvement of crime prevention can be expected.

  (N) In the second embodiment, it is possible to provide a pull-down resistor between the discharge switches 359 and 369 and the ground (earth). Thereby, the electric charge stored in the drain capacitor 356 etc. can be discharged more suitably.

  (O) In the third and fourth embodiments, the record holding circuits 350, 420, etc. are arranged on the main control board 301 or each monitoring device 420, etc., but this is changed and arranged on the relay board 300. Is also possible.

  (P) In each of the above-described embodiments, the coil spring 192 or the like is used as the “biasing means”. However, this may be changed to a configuration using a leaf spring, rubber, or the like.

  (Q) In each of the above embodiments, the bobbin 272 is used as the attachment member of the coil 271, but it is also possible to adopt a configuration in which this is not used.

  (R) In each of the above embodiments, the signals from the monitoring devices 250 and 290 are input to the main control device 162, but this is changed so that the signals from the monitoring devices 250 and 290 are sound lamps. It is also possible to adopt a configuration in which it is input to another control device such as the control device 143. That is, it is also possible to adopt a configuration in which opening / closing of the gaming machine main part 12 or the like is detected in another control device.

  (S) In each of the above embodiments, as shown in FIG. 25 and FIG. 31, each of the detection state grasping process S314 to the detection state updating process S318 is performed only when the RAM erase switch is on. However, this can be changed as follows. That is, even when the RAM erasure switch is off, the same detection state grasping process S314 to detection state update process S318 may be performed. For example, the processes S314 to S318 may be added immediately before the output process S307 of the sound lamp initialization command.

  (T) In each of the embodiments described above, the front door frame 14 is supported by the main body frame 13. However, the front door frame 14 may be changed to be supported by the outer frame 11. It is. In addition, the rotation base end side of the front door frame 14 is configured to be on the same side as the rotation base end side of the main body frame 12. It is also possible to set the rotation base end side to the rotation front end side of the main body frame 12.

  (U) The present invention can be applied to other types of gaming machines different from the above embodiment. For example, the present invention can be applied to a ball game machine such as a pachinko machine, an arrangement ball machine, or a sparrow ball that uses a game ball as a game medium. Further, the present invention can be applied to a ball-use spinning machine (so-called parrot) that can use a game ball as a game medium and can play a game similar to a so-called slot machine.

  Each of the configurations in the embodiments described in detail above and the configurations in the different examples of (a) to (u) can be arbitrarily combined. For example, the configuration of each embodiment and a plurality of other examples may be combined.
