Description

  The present invention relates to a gaming machine having a key mechanism for locking a glass door and opening and closing thereof, and an alarm control device thereof.

  In a gaming machine such as a pachinko machine, the front glass door plays a role in preventing the game ball falling on the gaming board surface from being dissipated outside the gaming machine, and prevents the player from making fraud by touching the gaming board surface. It also plays a role for Since this glass door is openable and closable for maintenance work of the objects and nails provided on the game board surface, many mechanisms related to opening and closing of the glass door while maintaining the above role Is given to gaming machines.

  First, as a mechanism for ensuring the role of the glass door for preventing the game ball from being dissipated outside the game machine, there is a mechanism related to a game ball launching device. For example, if a game ball is caught between nails planted on the game board surface, or if a ball is caught between the movable pieces of an electric tulip, Opened the glass door and manually removed the game ball. If a game ball is fired while the hall clerk is opening the glass door, the game ball is dissipated outside the game machine and is wasted. On the other hand, in Patent Document 1, a micro switch is provided on the back side of the glass door so that the opening of the glass door can be detected, and the operation of the game ball launching device is stopped according to the detection signal. A gaming machine provided with a device is disclosed. According to the gaming machine having such a device, even when the launching knob is rotated by the player when the glass door is opened, the gaming ball is not fired, so that the gaming ball is prevented from dissipating outside the gaming machine. It can be done.

Furthermore, as a mechanism for ensuring the role of the glass door to prevent the player from making fraud such as bending a nail by touching the game board surface, there is a mechanism related to a key for locking the glass door. . Generally, the glass door is provided with a key mechanism for locking the glass door so that only a hall attendant can open and close it. However, the glass door may be opened by means such as breaking the key, and the game board surface may be illegally contacted. On the other hand, Patent Document 2 discloses a gaming machine provided with a device that issues an alarm when a glass door is opened without using a key. The gaming machine has a sensor for detecting the opening of the glass door and a sensor for detecting that a key is set in the keyhole. When the glass door is opened without setting the key in the keyhole, the gaming machine 2 A signal from two sensors determines that this is illegal and issues an alarm.

  The game ball falling on the game board finally reaches the discharge port at the bottom of the game area while colliding with a nail or an accessory. Accordingly, it takes a considerable amount of time until the game ball launched into the game area on the game board surface is collected into the game machine from the discharge port or the like. Therefore, even if the game ball launching device is stopped after the glass door is opened, the game ball that has already been launched into the game area may be dissipated from the open gap of the glass door to the outside of the gaming machine. is there. Therefore, there is a need for a mechanism for preventing the game balls that have already been launched into the game area when the glass door is opened from being dissipated outside the game machine.

  Moreover, when a key leaks out from the hall | hole which stores the key for locking the opening and closing of a glass door, or when the copy of a key is circulated, a glass door may be opened using this. In such a case, since the sensor that detects that the key is set in the keyhole reacts normally, even if the glass door is opened, fraud cannot be detected. Therefore, there is a need for a reliable mechanism that makes it difficult for anyone other than the hall attendant to illegally contact the game board surface.

  The present invention has been made from the background as described above, and a gaming machine in which game balls are not dissipated to the outside of the gaming machine, and other than a staff member of the hall cannot easily touch the gaming board surface illegally, and for the same The purpose is to provide an alarm control device.

  A gaming machine according to the present invention is a gaming machine that operates a handle having a glass door that protects a gaming board and a door opening detection sensor that detects the opening of the glass door to launch a gaming ball onto the gaming board surface. A lock that maintains the closed state of the glass door, a key mechanism that releases the lock state of the lock, and a key insertion detection sensor that detects insertion of a key into a key hole of the key mechanism. And

  According to the present invention, since it can be detected that a key has been inserted into the keyhole of the key mechanism, even if the player tries to open the glass door while operating the handle, this can be detected at the time of inserting the key. Can do it. Therefore, since the player can stop the launch of the game ball before the glass door is opened, the game ball can be prevented from being dissipated outside the game machine. In addition, it is possible to detect that the key has been inserted into the keyhole of the key mechanism and to detect the opening of the glass door, so it is possible to detect fraud in opening the glass door without using the key. is there. Also, it is possible to detect fraud faster by detecting that a key has been inserted into the keyhole of the key mechanism. Therefore, it is possible to make it difficult for anyone other than the staff in the hall to illegally contact the game board surface.

  The alarm control device according to the present invention includes a glass door that protects the game board, a door opening detection sensor that detects the opening of the glass door, and a touch that detects a player's contact with a handle that fires a game ball. A sensor, a lock mechanism that maintains the closed state of the glass door, a key mechanism that releases the lock state of the lock mechanism, and a key insertion detection sensor that detects insertion of a key into a key hole of the key mechanism. An alarm control device for a gaming machine, wherein a fraud alarm means for issuing a fraud alarm in response to a door opening detection signal from the door opening detection sensor when there is no key insertion detection signal from the key insertion detection sensor, and the key First alarm means for issuing a first alarm in response to a key insertion detection signal from the insertion detection sensor and a touch detection signal from the touch sensor, and a key from the key insertion detection sensor And incoming detection signal and the second warning means for issuing a second warning in response to the touch detection signal from the touch sensor, and having a.

  According to the present invention, it is possible to detect the player's contact with the handle for launching the game ball, and to detect that the key has been inserted into the keyhole of the key mechanism and to issue the first alarm. It is possible to detect at the time of inserting the key that the user tries to open the glass door while operating the handle. Therefore, the launch of the game ball can be stopped before the glass door is opened, and the game ball can be prevented from being dissipated outside the game machine. In addition to detecting the opening of the glass door, it can also detect that a key has been inserted into the keyhole of the key mechanism and issue a fraud alarm, so it can detect fraud that opens the glass door without using a key. Can do it. Therefore, it is possible to make it difficult for anyone other than the staff in the hall to illegally contact the game board surface. Furthermore, since the alarm control device can be provided inside or outside the gaming machine, the installation location of the alarm control device can be freely determined according to the type of alarm.

BEST MODE FOR CARRYING OUT THE INVENTION

  The gaming machine according to the present invention has a glass door that protects the game board, a door opening detection sensor including a micro switch and an optical switch that detects opening of the glass door, and a player's contact with a handle that fires a game ball. A game machine having a touch sensor to detect. The gaming machine includes a lock that maintains the closed state of the glass door, a key mechanism that releases the lock state of the lock, and a key insertion detection sensor that detects insertion of a key into the key hole of the key mechanism.

  Here, the gaming machine has a fraud alarm means for issuing a fraud alarm in response to the door opening detection signal from the door opening detection sensor when there is no key insertion detection signal from the key insertion detection sensor. As a result, fraud such as opening the glass door without using a key, for example, opening a hole in the main body of the gaming machine and inserting a jig from the hole to unlock the glass door and opening the glass door An alarm can be issued in such a case. Since such a warning has already been opened, a warning with a high degree of urgency is given.

  The gaming machine has first alarm means for issuing a first alarm in response to a key insertion detection signal from the key insertion detection sensor and a touch detection signal from the touch sensor. As a result, it is possible to quickly detect at the point of insertion of the key that a player in the hall tries to open the glass door while operating the handle. Therefore, it is possible to prevent dissipating these balls, including game balls that have already been launched into the game board, from outside the gaming machine. A mechanism for stopping the launch of the game ball together with the first alarm may be provided.

  The gaming machine includes second alarm means for issuing a second alarm in response to a door opening detection signal from the door opening detection sensor and a touch detection signal from the touch sensor. As a result, following the first alarm, an alarm can be issued for actually trying to open the glass door while operating the handle. Therefore, it is possible to reliably prevent the game ball from being dissipated outside the game machine. Since such an alarm has already been opened, an alarm with a higher degree of urgency than the first alarm is given. Similarly to the first alarm, a mechanism for stopping the launch of the game ball together with the second alarm may be provided. This is because if the handle is not operated at the time of key insertion, the first alarm is not issued, but only the second alarm is issued when the handle is operated when the door is opened thereafter.

  The gaming machine has third alarm means for issuing a third alarm in response to the key insertion detection signal from the key insertion detection sensor when there is no touch detection signal from the touch sensor. As a result, it can be confirmed at an earlier stage whether or not the key is inserted due to a valid reason such as a staff member of the hall, and fraud can be prevented. Such an alarm is mainly an alarm for prompting the staff in the hall to confirm, and should be a mild alarm in consideration of the influence on surrounding players, but should be an alarm for an unauthorized person. For example, the third alarm may be strongly issued in an alarm control device provided outside the gaming machine, and may prompt the staff to confirm.

  Note that the key insertion detection sensor may react only when a regular key is inserted. That is, even if a foreign object is inserted into the keyhole, the key insertion detection sensor does not react. At this time, when a foreign object is inserted into the keyhole, the door does not open, so that the first alarm need not be issued. Further, since it is not necessary to consider the useless balls until the door is opened due to the insertion of the foreign object, the first alarm need not be issued. On the other hand, when a foreign object is inserted into the keyhole and the door is opened, a fraud alarm can be issued.

  By the way, the fraud alarm means, the first alarm means, the second alarm means, and the third alarm means may be provided in an alarm control device at a position separated from the gaming machine. The alarm control device is installed at a position away from the gaming machine that is in a state where an alarm should be issued, so that only the staff in the hall can receive the alarm without being noticed by those around the gaming machine. . In addition, there may be a plurality of gaming machines managed by the alarm control device. At this time, the alarm control device receives detection signals from the key insertion detection sensor, the door opening detection sensor, and the touch sensor of each gaming machine. Thus, the necessity of the fraud alarm, the first alarm, the second alarm, and the third alarm is determined for each gaming machine. It is preferable that the alarm control device has a means for specifying a gaming machine that is determined to need an alarm. This eliminates the need to provide an alarm control device for each gaming machine, thereby reducing costs.

  An embodiment of a gaming machine according to the present invention will be described in detail with reference to FIGS.

  In particular, as shown in FIGS. 1 and 2, the gaming machine 1 is a gaming machine that launches a game ball such as a pachinko machine toward the game area of the game board 2 and plays a game. The gaming machine 1 includes a main body 31 and a front glass door 32 attached to the main body 31 so as to be freely opened. A central accessory device 3 is provided at the center of the game board 2. The central accessory device 3 has a concave portion 4 at the central portion thereof, and a substantially rectangular display portion 3a is attached to the rear of the concave portion 4, that is, at the bottom portion, substantially parallel to the surface of the game board 2. The display unit 3a is composed of a liquid crystal panel or the like, and displays various game information. There is a stage 5 that extends in a substantially horizontal plane and retains a game ball on the lower part of the recess 4 of the central accessory device 3. A central portion of the stage 5 has a groove portion 5 a formed so as to extend in a direction perpendicular to the game board 1. On both sides of the central accessory device 3, there is a prize opening device 6 that guides the game ball into the recess 4 of the central accessory device 3. The winning opening device 6 has an opening directed upward so as to receive the game ball falling on the game board 1, and the opening is formed on the side wall of the recess 4 of the central player device 3 by a game ball guide passage (not shown). It communicates with the opening. That is, the game ball that has entered the opening of the winning opening device 6 is guided to the inside of the recess 4 from the opening of the side wall (not shown) through the communication passage (not shown) and falls onto the stage 5. This part of the game balls falls into the groove 5 a, travels along the groove 5 a, and falls from the central accessory device 3 in a direction perpendicular to the game board 2. A part of the game balls falls from the portion other than the groove 5a to the lower side of the central accessory device 3. Below the fall path from the groove 5a is a start winning opening (chucker) 7 having an opening directed upward. When a game ball enters the start winning opening 7, a sensor (not shown) detects this and a lottery is performed inside a game control CPU 91 (see FIG. 4) of the game control unit 101 described later.

  Below the start winning port 7, a large winning port device 8 is provided. The big prize opening device 8 is opened for a predetermined time when a game ball enters the starting prize opening 7 and a “win” is obtained as a result of an internal lottery performed by the game control CPU 91 of the game control unit 101. As a result, the game ball can enter the inside. When a game ball enters the big prize opening, a certain number of prize balls are paid back to the player. At the bottom of the game area of the game board 2, a discharge port 9 for collecting the game balls inside the game machine 1 as a final “disconnection” is provided.

  A grip-like handle 11 for launching a game ball into the game area is provided on the right hand when the gaming machine 1 is viewed from the front. A ring 12 is rotatably fitted to the handle 11, and when the player rotates the ring 12, the speed of the game ball launched into the game area of the game board 2 can be adjusted according to the rotation angle. It is. The ring 12 is provided with a touch sensor 51 (see FIG. 4) for detecting that a player is touching the ring 12. A signal from the touch sensor 51 is sent to an alarm control CPU 92 of the alarm control unit 102 described later.

  A hinge 33 is attached to the left side of the front glass door 32 when the gaming machine 1 is viewed from the front, and the front glass door 32 is pivotally attached to the left side of the main body 31. The front glass door 32 and the main body 31 are provided with a key mechanism for maintaining these closed states.

  Referring to FIG. 3 in particular, vertically extending through holes 31a are provided at two locations on the right side of the chassis 31 'of the main body 31. Since the structures of the two key mechanisms are the same, only one of the key mechanisms will be described here. A claw member 17 which is a plate-like member and has a substantially rectangular cutout portion 17a in the vicinity of one end thereof is inserted into the through hole 31a. The claw member 17 is pivotally supported so that the chassis 31 ′ is positioned inside the notch 17 a so that the chassis 31 ′ can be opened around the rotation pin 17 b near the center. The rotating pin 17b is on the back side of the chassis 31 '. In the vicinity of the rear end of the claw member 17 located on the back side of the chassis 31 ', a spring 19 having one end fixed to a stay 18 standing on the back side of the chassis 31' is attached. By this spring 19, the claw member 17 is urged counterclockwise in FIG. At this time, the bottom 17a 'of the notch 17a abuts on the peripheral edge of the through hole 31a, and the claw member 17 is stopped. Further, an inclined portion 17c is formed in front of the notch 17a of the claw member 17 so as to be inclined so as to reduce the width in the distal direction.

  Here, when the front glass door 32 approaches the main body 31 around the hinge 33, the hook 20 attached to the back side of the front glass door 32 contacts the inclined portion 17 c at the tip of the claw member 17. Further, when the front glass door 32 moves toward the main body 31, the hook 20 rotates the claw member 17 clockwise around the rotation pin 17 b while slidingly contacting the inclined portion 17 c of the claw member 17. When the hook 20 exceeds the inclined portion 17c, the hook 20 enters the inside of the notch 17a, and the claw member 17 rotates about the rotation pin 17b in the counterclockwise direction by the contraction force of the spring 19. Then, the notch 17a ′ of the claw member 17a again comes into contact with the peripheral edge of the through hole 31a and stops. As a result, the hook 20 is in the notch 17 a ′ of the claw member 17, and the front glass door 32 is restricted from moving away from the main body 31. That is, it will be in the locked state which maintains the closed state of the front glass door 32. FIG.

  Further, when the key 22 is inserted into the key hole 21 provided in the chassis 31 'on the right side of the main body 31 and turned, a spring near the rear end of the claw member 17 on the back side of the chassis 31' is connected by a link mechanism (not shown). A force F in such a direction as to extend 19 is applied. As a result, the claw member 17 rotates about the rotation pin 17b in the clockwise direction in FIG. 3, and a part of the notch 17a ′ of the claw member 17 contacts the back side of the chassis 31 ′ (FIG. (See dashed line 3). As a result, the hook 20 is positioned outside the notch 17a ', so that the engagement between the claw member 17 and the hook 20 is released. That is, the front glass door 32 is rotatable with respect to the main body 31.

  Here, when the hook 20 and the claw member 17 are separated from each other, a door opening detection sensor 52 that detects this and generates a signal is provided in the gaming machine 1 (see FIG. 4). The door opening detection sensor 52 is an electrical continuity sensor that detects contact between the claw member 17 and the hook 20, and sends a signal to the alarm control CPU 92 of the alarm control unit 102 when the claw member 17 and the hook 20 are separated. . The door opening detection sensor 52 may be any sensor that can detect that the front glass door 32 has been opened, and may be a micro switch or an optical detection switch. However, if it is an electrical continuity sensor, it can react even if the opening angle of the front glass door 32 is small, and this can be detected quickly and reliably.

  The keyhole 21 is provided with a key insertion detection sensor 53 that emits a detection signal when a proper key 22 corresponding to the keyhole 21 is inserted (see FIG. 4). That is, even if a foreign object is inserted into the keyhole 21, a detection signal from the key insertion detection sensor 53 is not issued. The keyhole 21 and the key 22 may be electric locks. In such a case, it is preferable because it becomes easy to obtain a detection signal indicating whether or not the regular key 22 has been inserted into the keyhole 21. If the key 22 is an electric lock, the force F for moving the claw member 17 is preferably given by a motor, a solenoid or the like.

  Referring particularly to FIG. 4, the game control unit 101 that determines the game content includes a game control CPU 91. A RAM 91 a and a ROM 91 b are connected to the game control CPU 91. The alarm control unit 102 includes an alarm control CPU 92. A RAM 92a and a ROM 92b are connected to the alarm control CPU 92. The alarm control CPU 92 is connected to three sensors: a touch sensor 51, a door opening detection sensor 52, and a key insertion detection sensor 53. Further, the alarm control CPU 92 is connected to an alarm device 61 including a speaker that emits an audio alarm according to the type of the alarm signal, an optical flash that emits a visual alarm, and the like.

  Next, the operation of the gaming machine 1 according to the present invention will be described with reference to FIGS.

  In particular, referring to FIGS. 4 and 5, the alarm control CPU 92 of the alarm control unit 102 always executes a detection routine. First, it is detected whether or not a key insertion detection signal notifying the key insertion from the key insertion detection sensor 53 is received (S01). When the signal is received, the parameter K is set to 1, and when the signal is not received, the parameter K is set to 0 and the value is transferred to the RAM 92b connected to the alarm control CPU 92. Next, it is detected whether or not a door opening detection signal notifying the opening of the door from the door opening detection sensor 52 is received (S02). When the signal is received, the parameter T is set to 1, and when the signal is not received, the parameter T is set to 0 and the value is transferred to the RAM 92b. Further, it is detected whether or not a touch detection signal notifying whether or not the player is touching the handle 11 from the touch sensor 51 is received (S03). When the signal is received, the parameter H is set to 1, and when the signal is not received, the parameter H is set to 0 and the value is transferred to the RAM 92b. The procedure for acquiring parameters by signals from the key insertion detection sensor 53, the door opening detection sensor 52, and the touch sensor 51 may be performed in any order.

  4 and 6 in particular, the alarm control CPU 92 of the alarm control unit 102 executes an alarm routine following the detection routine.

  First, it is determined whether the parameters K, T, and H in the RAM 92a are the same as the parameters K ′, T ′, and H ′ in the previous detection routine that are also stored in the RAM 92a (S11). . If they match, the alarm routine is terminated because the same alarm has already been issued. When the detection routine is executed for the first time, the parameters K ′, T ′ and H ′ are not stored in the RAM 92a, so the parameters K, T and H are changed to the parameters K ′, T ′ and H ′. There is no coincidence, and the process always proceeds to the next step.

  Next, it is determined whether or not (K, T) = (0, 1) for the parameters K and T in the RAM 92a (S12). That is, the fraud in which the front glass door 32 is opened even though the key 22 is not inserted into the keyhole 21 is detected. When this condition is detected, the alarm control CPU 92 acquires a fraud alarm signal stored in advance in the ROM 92b and sends the signal to the alarm device 61. At this time, the alarm device 61 functions as a fraud alarm means, and issues a fraud alarm upon receiving such a signal. In addition, it is preferable to continue issuing an alarm without being reset until the power is turned off when the alarm device 61 issues a fraud alarm. The fraud alarm is an alarm for notifying the staff in the hall of the fraud, and may be a voice alarm such as “The door has been opened without using a key” or a siren. On the other hand, when the above conditions are not satisfied, the process proceeds to the next step.

  It is determined whether or not (T, H) = (1, 1) for the parameters T and H in the RAM 92a (S13). That is, a case is detected where the front glass door 32 is opened while the handle 11 is operated and the game ball is likely to be dissipated to the outside of the gaming machine 1. When this condition is detected, the alarm control CPU 92 acquires a corresponding second alarm signal stored in advance in the ROM 92 b and sends it to the alarm device 61. At this time, the alarm device 61 functions as a second alarm means, and receives the signal to issue a second alarm. The second alarm is an audio alarm such as “The front door is open. Please release the handle.” It is an alarm for prompting the player to release the handle 11. Since this is an alarm that is more urgent than the first alarm described later, the player should be alerted more strongly than the first alarm. For example, the volume should be higher than that of the first alarm, or a visual alarm by flash should be combined. When the alarm control CPU 92 sends a signal to the alarm device 61, the parameters K, T and H are substituted for the parameters K ', T' and H ', respectively, and overwritten in the RAM 92a (S17). This terminates the alarm routine. On the other hand, when the above conditions are not satisfied, the process proceeds to the next step.

  Next, it is determined whether or not (K, H) = (1, 1) for the parameters K and H in the RAM 92a (S14). In other words, the case where the key 22 is inserted into the keyhole 21 while the handle 11 is being operated and the front glass door 32 is about to be opened, and the game ball is likely to be dissipated to the outside of the gaming machine 1 is detected. -ing When this condition is detected, the alarm control CPU 92 acquires a corresponding first alarm signal stored in advance in the ROM 92 b and sends it to the alarm device 61. At this time, the alarm device 61 functions as a first alarm means, and receives the signal to issue a first alarm. The first alarm is an audio signal such as “A key has been inserted. Please release the handle.” This is a signal for prompting the player to release the handle 11. When the alarm control CPU 92 sends a signal to the alarm device 61, the parameters K, T and H are substituted for the parameters K ', T' and H ', respectively, and overwritten in the RAM 92a (S17). This terminates the alarm routine. On the other hand, when the above conditions are not satisfied, the process proceeds to the next step.

  Next, it is determined whether or not K = 1 for the parameter K in the RAM 92a (S15). That is, this is a case where the key 22 is inserted into the keyhole 21 and the front glass door 32 is about to be opened. Here, since this step is executed when the first alarm is not issued, H is always 0. That is, the handle 11 is not operated. The reason why the key 22 is inserted into the keyhole 21 without operating the handle 11 may be that a person in charge of the hall opens the front glass door 32 without permission due to a clogged ball or the like, or a player may open it illegally. . When this condition is detected, the alarm control CPU 92 acquires a corresponding third alarm signal stored in advance in the ROM 92 b and sends it to the alarm device 61. At this time, the alarm device 61 functions as a third alarm means, and receives the signal to issue a third alarm. The third alarm is an audio signal such as “A key has been inserted.” When an attendant in the hall opens the front glass door 32, the player's game around the gaming machine is not disturbed. Must be an alarm. In the case of fraud, an alarm is provided to prevent the front glass door from being opened. Here, since the fraud is performed after the glass door is opened, the third alarm is made earlier so that the hall staff can confirm whether the insertion of the key 22 into the keyhole 21 is fraudulent. It can be done. When the alarm control CPU 92 sends a signal to the alarm device 61, the parameters K, T and H are substituted for the parameters K ', T' and H ', respectively, and overwritten in the RAM 92a (S17). This terminates the alarm routine. On the other hand, when the above conditions are not satisfied, the process proceeds to the next step.

  When the conditions are not satisfied in the above steps, the alarm is not issued or the alarm should be canceled. Therefore, a signal for canceling the alarm is sent to the alarm device 61 (S16). Then, the parameters K, T, and H are assigned to the parameters K ′, T ′, and H ′, respectively, and overwritten in the RAM 92a (S17). This terminates the alarm routine.

  In the above alarm routines, the alarms with higher urgency are given priority. Therefore, even if a state where a certain alarm is generated is healed, the alarm is continuously generated if a milder alarm is generated.

Table 1 summarizes sensor signals and alarm types.

  Further, another embodiment of the alarm control device according to the present invention will be described with reference to FIG.

  One alarm control device 71 is provided for a plurality of gaming machines 1. The alarm control device 71 is separated from the gaming machine 1 and is installed, for example, in a control room of a hall. Each of the plurality of gaming machines 1 has a touch sensor 51, a door opening detection sensor 52, and a key insertion detection sensor 53, and outputs thereof are sent to a repeater 93 for each gaming machine 1. The details of the sensor are the same as in the case of the gaming machine 1 of the first embodiment, and will not be described in detail. The alarm control device 71 includes an alarm control CPU 92, a RAM 92 a and a ROM 92 b connected thereto, and an alarm device 61. The detection signals of the touch sensor 51, the door opening detection sensor 52 and the key insertion detection sensor 53 of each gaming machine 1 are sent to the alarm control CPU 92 of the alarm control device 71 via the relay device 93 of each gaming machine 1 or directly. Sent out. The alarm control CPU 92 executes a detection routine and an alarm routine for each gaming machine 1 that has sent out these signals. When it is necessary to issue an alarm, the alarm device 61 issues an alarm while displaying this on the display device that identifies the gaming machine 1 that has issued the alarm.

  The detection routine and alarm routine are the same as described above, and will not be described in detail.

  In the alarm control device 71 described above, the alarm device 61 may be a wireless portable terminal that receives a signal by radio waves. In this case, a plurality of portable terminals may be provided and the hall staff may have. Such a portable terminal is preferable because the place for receiving the alarm is not limited.
