Description

  The present invention relates to a gaming machine island in which a plurality of gaming machines form a group, and particularly relates to a storage tank that stores gaming media provided in the gaming machine island.

  A game arcade where game machines such as pachinko machines and slot machines are installed is generally configured to include a plurality of game machine groups (so-called game machine islands) in which a plurality of game machines form a group (hereinafter referred to as “game machine islands”). I will focus on the pachinko machine and explain it). And inside each gaming machine island, in order to smoothly operate each group of pachinko machines, a transport path for transporting game balls (hereinafter simply referred to as spheres) and a storage for temporarily storing the balls A tank (island tank), a ball polishing device, a lifting device, and the like are provided.

  By the way, the supply of the balls to the pachinko machines on the gaming machine island is performed as needed from an island tank disposed higher than the position where the pachinko machines are installed. In other words, the island tank is always controlled in such a way that a predetermined amount (for example, about 20,000 balls) is stored so that it can always meet the demand from the pachinko machine. Therefore, the island tank on the gaming machine island is always in a state where the mass of one sphere (about 5.5 g) × the total sphere mass calculated by the predetermined amount of formula is generated.

  In this way, in gaming machine islands, a large amount of balls can be stored in advance in the island tanks and respond quickly to requests from each pachinko machine, which is efficient from the viewpoint of smoothing the game. It can be said that this is a simple configuration.

  However, in view of the structural balance of gaming machine islands, it is not necessarily a preferable configuration. In other words, the island tank has a higher center of gravity of the entire gaming machine island than the state where the ball is not stored. It can be said that the structure is easily affected by shaking such as an earthquake. In this way, this type of gaming machine island has a high center of gravity due to the island tank, and thus is highly likely to amplify shaking such as an earthquake. Therefore, if a large shaking earthquake occurs and the swing of the gaming machine island itself is amplified by the island tank, the gaming machine island may collapse and cause a human disaster caused by the gaming machine island. It was.

  In order to solve such a problem, Patent Document 1 discloses a technique for installing a heavy object at a low position on the gaming machine island and adjusting the balance of the center of gravity of the entire gaming machine island downward. In other words, Patent Document 1 is configured to improve the earthquake resistance of the gaming machine island by changing the center of gravity of the gaming machine island downward to reduce the influence of shaking such as an earthquake. Thereby, the possibility that the gaming machine island itself collapses due to a shake such as an earthquake is reduced.

JP 9-327570 A

However, in the gaming machine island of Patent Document 1, there is a high possibility that the island tank will fall on the floor of the game hall.
To describe this in detail, Patent Document 1 is a measure for preventing the collapse of the gaming machine island itself using heavy objects, and even if a large shake is observed, a sphere remains in the tank on the island, The weight of the entire island tank remains heavy. Therefore, the burden caused by the shaking to the support portion that supports the island tank is large, and the proof stress of the support portion is likely to reach the limit as compared with the case of supporting a lightweight supported member. Therefore, in Patent Document 1, since the weight of the island tank is heavy when the shaking occurs, there is still a high possibility that the island tank will fall on the floor of the game hall. As described above, Patent Document 1 can reduce the possibility of collapse of the gaming machine island itself, but has a problem that the tank on the island falls, and further improvement is desired.

  Therefore, in the present invention, in view of the problems of the prior art, it is possible to greatly reduce the possibility of the island tank falling to the floor when a large earthquake occurs, and even if the island tank falls, it is reduced in weight. An object is to provide an amusement machine island that can suppress the occurrence of human disasters.

  The invention according to claim 1, which is provided in order to solve the above-mentioned problem, is configured such that a plurality of ball game machines are installed in groups and are arranged at positions higher than the installation positions of the ball game machines. A gaming machine island having an upper storage tank for supplying game balls to a ball game machine, wherein the game ball is discharged downward from the upper storage tank, and the inflow of game balls to the discharge channel When the acceleration sensor detects an acceleration of a predetermined value or more, the restriction means for limiting and the acceleration sensor for detecting the vibration are released, the restriction of the inflow to the discharge channel is canceled, and the game ball stored in the upper storage tank is It is a gaming machine island characterized by discharging through a discharge channel.

The gaming machine island of the present invention is configured such that the position of the center of gravity of the entire gaming machine island can be changed to the safe side in order to avoid a catastrophe that may occur due to an earthquake or the like. That is, in the present invention, an acceleration sensor that detects vibration is provided, and when the acceleration sensor detects an acceleration of a predetermined value or more, the upper storage disposed at a position higher than the installation position of the ball game machine. The game ball is forcibly discharged from the tank.
Here, generally, when a shake with a seismic intensity of less than 5 (strong shake) is observed due to an earthquake, the acceleration sensor detects a numerical value of about 80 to 250 in acceleration (gal).
That is, in the present invention, for example, when such a shake with a seismic intensity of less than 5 is observed, the game ball can be forcibly discharged from the upper storage tank. Therefore, in the present invention, a predetermined reference is set in advance for the numerical value detected by the acceleration sensor, and when the numerical value is exceeded, the gaming ball in the upper storage tank can be discharged. Even if vibrations that occur when flowing, vibrations caused by vehicles traveling on the road, or vibrations that occur during construction work in the vicinity are detected, there is no possibility that gaming balls will be accidentally discharged from the upper storage tank due to the vibrations. .

  As described above, the gaming machine island of the present invention discharges the gaming balls in the upper storage tank and moves the center of gravity of the entire gaming machine island downward when a so-called large earthquake occurs. Can do. As a result, it is possible to prevent the swing of the gaming machine island itself from being amplified. Further, in the present invention, when the acceleration sensor detects an acceleration equal to or higher than a predetermined value, the weight of the upper storage tank is reduced, so that the burden on the portion supporting the upper storage tank due to shaking can be reduced. Therefore, according to the present invention, it is possible to reduce the possibility that the upper storage tank will fall on the floor surface when an earthquake of a predetermined magnitude or larger occurs, and even if the upper storage tank falls to the floor surface. Even if it occurs, the damage of man-made disasters can be reduced because the upper storage tank is lighter.

  The invention according to claim 2 is based on the same knowledge as in claim 1, wherein a plurality of ball game machines are installed in groups, and the position of the ball game machine is set more than that. A gaming machine island having an upper storage tank that is arranged at a high position and supplies a game ball to each ball game machine, a discharge flow path for discharging the game ball downward from the upper storage tank, and a discharge flow path A limiting means for restricting the inflow of game balls to the vehicle, an acceleration sensor for detecting vibrations, and a time measuring means. The acceleration sensor first detects an acceleration of a predetermined value or more, and further after a certain period of time has passed. The game machine island is characterized in that when it is detected one or more times, the inflow restriction to the discharge channel is canceled and the game balls stored in the upper storage tank are discharged through the discharge channel.

  According to this configuration, when the acceleration sensor first detects an acceleration of a predetermined value or more and then detects one or more times during a predetermined time, the game ball stored in the upper storage tank is discharged. The possibility of causing false detection of vibration can be reduced. That is, when a single vibration occurs for some reason and the vibration is not an earthquake, it is possible to prevent a problem that the game ball is accidentally discharged from the upper storage tank. Therefore, in the present invention, the game ball stored in the upper storage tank can be discharged with high accuracy by ensuring the earthquake detection by the acceleration sensor.

  The invention according to claim 3 is provided at a position lower than the installation position of the ball game machine, a lower storage tank into which a game ball that has passed above the installation position of the ball game machine is introduced, The gaming machine island according to claim 1 or 2, wherein the game ball that has passed through the discharge channel is introduced into a lower storage tank.

  According to this configuration, since the game ball that has passed through the discharge channel is introduced into the lower storage tank that is normally installed on the gaming machine island, the game ball can be placed at a predetermined place without newly providing a dedicated tank. You can save it. As a result, in the present invention, the capital investment cost can be minimized. Therefore, according to this invention, it can be set as the rational structure using the existing installation.

  In the invention according to claim 4, a lower storage tank into which a game ball that has passed above the installation position of the ball game machine is introduced at a position lower than the installation position of the ball game machine; The gaming machine island according to claim 1 or 2, wherein a temporary tank to be used is provided, and the game ball that has passed through the discharge channel is introduced into the temporary tank.

  According to such a configuration, a temporary tank is newly provided, and the game ball that has passed through the discharge channel is introduced into the temporary tank. For example, the temporary tank is placed at a position lower than the installation position of the ball game machine. If it is provided near the upper storage tank, the game ball can be sent to the lower side of the gaming machine island in a short time. That is, according to the present invention, even in the case where shaking continuously occurs in a short time, the game balls in the upper storage tank are discharged to a predetermined location below in a short time. Therefore, the possibility of occurrence of the amplified vibration is extremely low.

Here, generally, the upper storage tank is configured to always store a predetermined amount or more of game balls. That is, if the game balls stored in the upper storage tank are discharged and reduced due to a request from the ball game machine side or the like, the upper storage tank is lifted and replenished from below. Therefore, even when the game ball in the upper storage tank is discharged through the discharge channel, it is conceivable that the reduced amount is replenished.
Therefore, in order to solve such a problem, the invention according to claim 5 is characterized in that when the game ball is passed through the discharge channel, the operation of introducing the game ball into the upper storage tank is stopped. It was set as the gaming machine island according to any one of claims 1 to 4.

  According to such a configuration, when a game ball is caused to flow through the discharge channel, the reduced amount of the game ball discharged from the upper storage tank is not replenished into the upper storage tank via the discharge channel. . That is, since a meaningless circulation cycle is prevented, the game ball can be efficiently discharged from the upper storage tank.

  In the gaming machine island of the present invention, if the acceleration fluctuation of a predetermined value or more is detected, the game balls stored in the upper storage tank are discharged from the discharge flow path, so that the weight of the upper storage tank can be reduced. it can. Thereby, since the center of gravity of the entire gaming machine island can be lowered, it is possible to prevent the shaking of the gaming machine island itself from being amplified. Furthermore, the weight of the upper storage tank is greatly reduced because the load on the portion that supports the upper storage tank is greatly reduced, so that the possibility of the upper storage tank falling onto the floor surface can be reduced. Even if the upper storage tank falls to the floor, the upper storage tank is reduced in weight, so that the occurrence of human disasters can be suppressed.

Below, game machine island 1 concerning the embodiment of the present invention is explained.
In the gaming machine island 1 of this embodiment, a plurality of ball game machines (hereinafter referred to as pachinko machines) 30 form one group, and a plurality of such groups are installed to form a game hall. Is.
In the following description, in order to facilitate understanding, description will be made with attention paid to one gaming machine island 1.

The gaming machine island 1 is formed by attaching a pachinko machine 30 to a frame-shaped gaming machine mounting portion 31 provided on the island structure 28.
The island structure 28 is a substantially rectangular parallelepiped box-shaped structure, and includes a pillar member (not shown) and a beam member (not shown) as bone members, and a decorative member 32 as a wall surface forming member. That is, in the island structure 28, a framework is formed by a bone member, and the decorative member 32 is attached so as to surround the framework.

The gaming machine attachment portion 31 is an opening-shaped frame portion formed so as to communicate the inside and outside of the gaming machine island 1 at the position of the decorative member 32 having no framework. A plurality of gaming machine mounting portions 31 are provided side by side on the side surface in the longitudinal direction of the island structure 28. That is, the gaming machine mounting portions 31 as the frame portions are provided in two rows (only one row is shown in the figure). In other words, the gaming machine mounting portion 31 is arranged so that the pachinko machines 30 can be provided in two rows.
Therefore, an inner space 27 (FIG. 2) surrounded by the pachinko machine 30 and the decorative member 32 is formed in the gaming machine island 1.

  The internal space 27 is a device installation space in which members, devices, and the like necessary for smoothly operating the pachinko machines 30 are arranged. Specifically, inside the gaming machine island 1, a transport path 23 for transporting game balls (hereinafter simply referred to as balls), an island tank 24 for temporarily storing the balls, and a polishing apparatus for polishing the balls 25 and a lifting device 26 for lifting a ball are provided.

The conveyance path 23 is roughly divided into a longitudinal conveyance path 20 extending in the longitudinal direction of the gaming machine island 1, that is, a parallel arrangement direction of the pachinko machines 30, and a vertical conveyance path 21 extending in the height direction of the gaming machine island 1. There is.
The island tank 24 is similar to a known one, and is higher than the installation position of the two island tanks 14 and 15 disposed at a position lower than the installation position of the pachinko machine 30 and the pachinko machine 30. There is one island tank 16 arranged at the position. The island tank 24 is provided with a sphere amount detection sensor (not shown), and the sphere amount in the tank is monitored.

The polishing device 25 is the same as a known one, and is a device that removes dirt adhering to the sphere and further polishes it. Further, the polishing device 25 is provided at a position lower than the installation position of the pachinko machine 30 and substantially at the center in the longitudinal direction of the gaming machine island 1.
The lifting device 26 is the same as that known in the art and is a part of the vertical conveying path 21 and conveys the sphere upward. Further, the lifting device 26 is located lower than the position where the pachinko machine 30 is installed, and is provided at a substantially central position in the longitudinal direction of the gaming machine island 1 and downstream of the polishing device 25 in the conveying direction of the balls. .

  Further, the pachinko machine 30 and the electric devices that constitute the gaming machine island 1 are electrically connected to the hall computer 67 (FIG. 8) of the amusement hall, and the operation status of each device is managed.

  With the above configuration, in the gaming machine island 1, the balls polished by the polishing device 25 are introduced into the lifting device 26 and lifted upward. The ball lifted by the lifting device 26 is once introduced into the island tank 16 and then transported to a desired place. That is, if there is a request from each pachinko machine 30, a ball is supplied from the island tank 16 to the pachinko machine 30 via the horizontal conveyance path 20, and if the island tank 16 overflows, the excess ball is generated. It is transported to the longitudinal direction end side of the gaming machine island 1 and returned to the island tanks 14 and 15. Furthermore, if there is a request from an adjacent gaming machine island, a ball is supplied to the adjacent gaming machine island through another flow path (not shown).

  In the gaming machine island 1, as described above, the ball quantity in the island tank 24 is monitored by a ball quantity detection sensor (not shown). In particular, with respect to the island tank 16, if there is a request from the pachinko machine 30, it is necessary to quickly supply the balls. For this reason, the island tank 16 is always controlled so that more than a predetermined amount (about 20,000 in this embodiment) of balls are stored in the tank.

  In this way, in the gaming machine island 1, in order to facilitate the game, a state where a predetermined amount or more of balls are stored in the island tank 16 is always maintained as described above. Therefore, the island tank 16 has a considerable weight (mass per sphere (about 5.5 g / piece) × amount stored in the island tank 16) due to the stored sphere. The center of gravity of the entire gaming machine island 1 is relatively high compared to the state where there is no ball. Specifically, the gaming machine island 1 in this state has a center of gravity substantially in the center in the height direction of the gaming machine island 1 or slightly higher than that. For this reason, the gaming machine island 1 has a poor structural balance. Thus, when an earthquake is observed and the gaming machine island 1 itself shakes, the shake is amplified due to the poor balance. Along with that, the burden on the shaking received by the support portion (not shown) that supports the island tank 16 is increased, and the support portion is easily damaged. As a result, there is a high possibility that the island tank 16 in which the balls are stored will fall on the floor of the game hall, which may cause a catastrophe in the game hall.

Therefore, in this embodiment, in order to solve such a problem, a function of discharging a sphere from the island tank 16 is provided when a shake due to an earthquake is observed.
That is, the gaming machine island 1 of the present embodiment has a temporary opening 7 (FIG. 3) provided in the island-top tank 16, the discharge flow path 2, and the restriction means 3 that restricts the introduction of the sphere into the discharge flow path 2. And a temporary tank 5 that temporarily stores a sphere that has passed through the discharge flow path 2 and an acceleration sensor 6 (FIG. 8) that detects shaking due to an earthquake.

  The temporary openings 7 are two openings provided in the bottom 33 of the box-shaped island tank 16 shown in FIG. 3, and the vertical direction (member thickness direction) of the bottom 33 communicates with the openings. The temporary opening 7 is set so that a large amount of spheres can pass through at one time. Further, as shown in FIG. 4, the bottom 33 of the island tank 16 is provided with a central opening 35 through which the overflowed sphere passes almost at the center, and the temporary opening 7 is located between the central opening 35 ( One on each side).

  The discharge channel 2 is a long sphere channel formed of a hard resin (for example, polypropylene or the like). And the discharge flow path 2 is installed so that the ball | bowl discharged | emitted from the island tank 16 can be flowed linearly. More specifically, as shown in FIG. 2, the discharge flow path 2 is a flow path that connects the island tank 16 to a temporary tank 5 described later in a straight line.

  The restricting means 3 is an open / close device having a known rack and pinion mechanism and serving as a valve for restricting the passage of a sphere. That is, as shown in FIG. 4, the restricting means 3 includes an opening / closing member 10, a rack and pinion 11 that opens and closes the opening / closing member 10, and a case member 12 that accommodates them.

First, each member constituting the limiting unit 3 will be described.

Each protrusion 45 is formed by a pair of protrusions 46. The protruding pieces 46 are arranged so that the planes of the plates face each other, and the distance between them is set to be sufficiently shorter than the side t. Specifically, the interval between the protruding pieces 46 is set to such a size that the rack 11b of the rack and pinion 11 can be disposed. And the rotation side holding | maintenance part 41 is provided so that it may be located in the approximate center of the plane of each protrusion piece 46. As shown in FIG. More specifically, the rotation-side holding portion 41 is provided in such an arrangement that the longitudinal side edge of the opening is orthogonal to the side t and substantially parallel to the plane 36. That is, the rotation side holding portions 41 provided on the pair of protrusion pieces 46 are a pair of shaft holes whose opening edge portions overlap each other when projected in the penetrating direction. The rotation-side holding portion 41 has a short side opening width that is substantially the same as the outer diameter of the shaft member 53, and a long-side opening width that is approximately two to three times the outer diameter of the shaft member 53. It has been sized.

The rack and pinion 11 is substantially the same as a known one, and has a gear-like pinion 11a connected to a drive source and a rod-like rack 11b having a tooth surface. In the present embodiment, a motor built-in roller 50 in which a motor is built in a cylindrical body is employed as a drive source to which the pinion 11a is connected. Then, one pinion 11a is inserted into each end of the rotation shaft of the motor built-in roller 50. The rack 11b is provided with a rack-side shaft hole 51 communicating with the rotation-side holding portion 41 of the opening / closing member 10 on one end side in the longitudinal direction.
That is, in the present embodiment, the opening / closing member 10 is opened / closed by connecting the opening / closing member 10 via the rack-side shaft hole 51 of the rack 11b and moving the rack 11b linearly by the driving force transmitted to the pinion 11a. It is said that.

  As shown in FIGS. 4 and 5, the case member 12 is a case in which a large rectangular parallelepiped 55 and a small rectangular parallelepiped 56 are combined, as shown in FIGS. Specifically, the case member 12 is positioned on one lower rectangular parallelepiped 55 having an outer flange portion 66 having an open upper surface and projecting outward from an edge of the open portion, and a lower side surface of the large rectangular parallelepiped 55. The large rectangular parallelepiped 55 is formed with one small rectangular parallelepiped 56 communicating with the inside and outside. That is, the case member 12 has one opening on each of the upper part and the side part, and these openings communicate with each other through the internal spaces of the large rectangular parallelepiped 55 and the small rectangular parallelepiped 56.

  The rectangular parallelepiped 55 is provided with a pair of cutouts 48 on the side wall so as to hold the shaft member 52 inserted into the reference holding portion 40 of the opening / closing member 10. Specifically, the notch 48 is a pair of side walls (hereinafter referred to as intersecting side walls) k that intersects (substantially orthogonal in the present embodiment) j with a side wall (hereinafter referred to as a joined side wall) j to which the small rectangular parallelepiped 56 is joined. Therefore, it is provided closer to the side wall (hereinafter referred to as the opposite side wall) 1 facing the bonding side wall j. The notch 48 has a long hole shape directed downward from the open side end of the large rectangular parallelepiped 55, and the bottom is formed in a substantially circular shape.

  Further, as shown in FIGS. 4 to 6, an inclined portion 57 that extends from the large rectangular parallelepiped 55 to the small rectangular parallelepiped 56 is provided on the bottom wall of the case member 12. Specifically, the inclined portion 57 is a portion inclined downward from an intermediate position between the joining side wall j and the opposing side wall 1 toward the opening communicating with the outside in the small rectangular parallelepiped 56. On the other hand, the remaining portion of the bottom wall of the case member 12, that is, the bottom wall excluding the inclined portion 57 in the large rectangular parallelepiped 55 is a substantially horizontal horizontal portion 58. Therefore, a boundary line B serving as a boundary between the inclined portion 57 and the horizontal portion 58 is located on the bottom wall of the case member 12 and on the bottom wall of the large rectangular parallelepiped 55. Note that the boundary line B extends linearly along the joining side wall j or the opposing side wall 1 on the bottom wall of the case member 12.

  Further, as shown in FIG. 6, the case member 12 is provided with a partition wall 60 that rises toward the open side (upward) on the boundary line B of the bottom wall. Specifically, the partition wall 60 is erected almost vertically upward with respect to the horizontal portion 58 and bisects the space in the case member 12. That is, the partition wall 60 is a space dividing wall which is located inside the large rectangular parallelepiped 55 and bisects the internal space by connecting a pair of intersecting side walls k. The partition wall 60 is configured such that the height (length in the standing direction) is lower (shorter) than any of the side walls.

Then, the positional relationship of each member which comprises the limitation means 3 is demonstrated.
The restricting means 3 performs the valve function by moving the opening / closing member 10 in the rotational direction by using the mechanism of the rack and pinion 11, and the rack and pinion 11 disposed inside the case member 12 and the case member 12 It is comprised with the opening-and-closing member 10 arrange | positioned rotatably at the open part side. Specifically, as shown in FIGS. 5 and 6, the rack and pinion 11 is arranged inside the case member 12 so as to be located in a space on the horizontal portion 58 side (hereinafter, referred to as a horizontal space). . More specifically, the rack and pinion 11 is arranged in the horizontal space so that the longitudinal side surface of the rack 11b extends along the partition wall 60, and the tooth surface of the pinion 11a engages with the tooth surface of the rack 11b. Is arranged.

In the present embodiment, the motor built-in roller 50 having the pinion 11 a inserted therein is fixed to the case member 12 side, and the rack 11 b is attached so as to move relative to the case member 12. That is, the rack and pinion 11 is arranged in the case member 12 so that the rack 11b can be moved up and down along the partition wall 60 by the driving force transmitted to the pinion 11a.
In this embodiment, as shown in FIGS. 6 and 7, the position of the pinion 11 a is positioned higher than the horizontal portion 58 so that the movement range of the rack 11 b is accommodated in the case member 12. A gantry 63 is fixed to the motor, and the motor built-in roller 50 is fixed via the gantry 63.

The opening / closing member 10 is connected to the rack 11 b of the rack and pinion 11. Specifically, as shown in FIG. 6, the rack 11 b is arranged so that the rack side shaft hole 51 communicates with the shaft hole of the rotation side holding portion 41 of the opening / closing member 10, and the shaft 11 is connected to the shaft hole in the communication state. The member 53 is inserted. The shaft member 53 is provided with a drop-off prevention ring (not shown) so that the shaft member 53 does not fall out of the shaft hole itself.
Further, the opening / closing member 10 is inserted into the reference holding portion 40 so that the case member 12 supports the shaft member 52, and both end sides of the shaft member 52 are disposed in the notches 48 of the case member 12. That is, as shown in FIGS. 5 to 7, the opening / closing member 10 is supported in a state of being rotatable relative to the case member 12 via the shaft member 52 inserted through the reference holding portion 40. As with the shaft member 52, a drop-off prevention ring (not shown) is also mounted.
Therefore, the opening / closing member 10 attached in this way is rotated with reference to the closing posture parallel to the horizontal portion 58 and the shaft member 52 inserted into the reference holding portion 40 by the limiting means 3 from the closing posture. The posture can be changed to a tilted open posture.

In the present embodiment, the planar size of the opening / closing member 10 can close the temporary opening 7 of the island tank 16 as shown in FIGS. 5 and 7 in the closed posture, and in the open posture, The flat surface 36 on the rotation side holding portion 41 side is sized so as to contact the upper end of the partition wall 60. That is, when the opening / closing member 10 is in the open posture, the upper portion on the horizontal portion 58 side can be almost closed, and the size of the ball discharged from the island tank 16 does not flow into the horizontal space.
The above is the description of the limiting unit 3.

  The temporary tank 5 is a metal casing having an open upper surface, and is arranged at a position lower than the installation position of the pachinko machine 30. A connection portion (not shown) for connecting the discharge flow path 2 is provided in any of the cases of the temporary tank 5. That is, the sphere that has passed through the discharge channel 2 is introduced into the temporary tank 5 through the connection portion.

  The acceleration sensor 6 is a known seismometer and employs a sensor that has sensitivity in the vicinity of the period of the seismic wave and suppresses detection of vibrations other than earthquakes (those shorter than the period of the earthquake). And this acceleration sensor 6 is installed in any position of the floor surface in a game hall, and is monitoring the shake by an earthquake.

Next, the positional relationship of each member and each device on the gaming machine island 1 will be described.
As shown in FIG. 2, the gaming machine island 1 of the present embodiment is arranged at an island tank 16 disposed higher than the installation position of the pachinko machine 30 and at a lower position than the installation position of the pachinko machine 30. The restricting means 3 and the discharge channel 2 are arranged so as to connect the temporary tanks 5. Specifically, as shown in FIG. 6, the restricting means 3 is arranged such that the opening / closing member 10 in the closed posture closes the temporary opening 7 of the island tank 16, and the outer flange portion 65 of the case member 12 and the island top The bottom portion 33 of the tank 16 is connected using a fastening element (not shown) such as a screw.

  Then, one end of the discharge channel 2 is connected to the restriction means 3. Specifically, one end of the discharge channel 2 is connected to the opening of the small rectangular parallelepiped 56 of the restricting means 3 as shown in FIG. The other end of the discharge channel 2 is connected to a connection portion (not shown) of the temporary tank 5. That is, as shown in FIG. 2, the discharge flow path 2 is installed so as to have a downward slope from the island tank 16 side toward the temporary tank 5.

  Further, the limiting means 3 is electrically connected to the acceleration sensor 6. More specifically, as shown in FIG. 8, the limiting means 3 is electrically connected to the hall computer, and the hall computer 67 and the acceleration sensor 6 are electrically connected. That is, in the present embodiment, the operation of the limiting unit 3 is controlled based on the information of the acceleration sensor 6 received by the hall computer 67.

Next, the function of the gaming machine island 1 of this embodiment will be described.
The gaming machine island 1 of the present embodiment has a function of avoiding catastrophic events in the game hall that may occur when a large earthquake occurs. That is, when the acceleration sensor 6 detects an acceleration value greater than or equal to a predetermined value, the sphere in the island tank 16 is discharged downward. More specifically, the limiting means 3 is driven when the acceleration sensor 6 detects an acceleration value of 250 or more, preferably 80 to 250 or more, more preferably 80 or more, indicating a shaking with a seismic intensity of 5 or less. . That is, when an acceleration value equal to or greater than a predetermined value is detected, a signal for driving the rack and pinion 11 of the limiting means 3 is generated in the hall computer 67 that has received the information. The limiting means 3 that has received this signal moves the rack 11 b of the rack and pinion 11 downward along the partition wall 60. As a result, the opening / closing member 10 rotates downward with respect to the reference holding portion 40 to take an open posture. That is, the opening / closing member 10 of the restricting means 3 is changed from a state where the temporary opening 7 of the island tank 16 is closed to an opened state as shown in FIG. At this time, the opening / closing member 10 is in a state in which the flat surface 36 on the rotation side holding portion 41 side is close to the upper end of the partition wall 60 of the case member 12 and the upper portion of the horizontal space is substantially closed. That is, since the temporary opening 7 of the island tank 16 is opened by changing the posture of the opening / closing member 10, the sphere in the island tank 16 flows into the discharge channel 2 from the temporary opening 7 and faces downward. Discharged. And it introduce | transduces into the temporary tank 5 connected with the downstream end part of the discharge flow path 2. FIG.

  In this way, in this embodiment, if the earthquake shake is greater than or equal to a predetermined value, the ball in the island tank 16 can be discharged toward the temporary tank 5 below in order to avoid danger. The center of gravity of the island 1 can be changed to a stable position where the swing of the gaming machine island 1 itself cannot be amplified (a position lower than the center of the gaming machine island 1 in the height direction). As a result, the weight of the island tank 16 is reduced, so that the burden caused by the shaking received by the support member that supports the island tank 16 is reduced, and the island tank 16 falls to the floor side of the game hall due to the earthquake shake. The possibility of coming can be lowered. Moreover, in this embodiment, even if the situation which the island tank 16 falls by the shaking of an earthquake occurs, since the island tank 16 is reduced in weight by discharge | emission of a ball | bowl, damage can be suppressed small.

  In the above-described embodiment, the temporary tank 5 is prepared and the sphere that has passed through the discharge channel 2 is guided to the temporary tank 5. However, the present invention is not limited to this. For example, as shown in FIG. 10, the discharge channel 2 leads from the island tank 16 to the existing island tanks 14 and 15, or, as shown in FIG. It may be the structure which is not connected also to this member but discharges inside the gaming machine island. In short, if an acceleration value equal to or greater than a predetermined value is detected by the acceleration sensor 6, the ball stored in the island tank 16 may be discharged below the gaming machine island to change the center of gravity of the gaming machine island downward.

  In the above embodiment, when the acceleration sensor 6 observes a shake with a seismic intensity of 5 or less, the limiting means 3 is driven and the ball in the island tank 16 is discharged downward. The present invention is not limited to this, and for example, when a tremor with a seismic intensity of about 4 which is less than seismic intensity 5 or a seismic intensity of 5 is observed, the limiting means 3 may be driven.

  In the above embodiment, the configuration has been described in which the limiting unit 3 is driven when the acceleration sensor 6 detects an acceleration of a predetermined value or more even once. However, the present invention is not limited to this, and for example, a timing unit is provided. If the acceleration sensor 6 detects an acceleration value greater than or equal to a predetermined value for the first time and detects an acceleration value greater than or equal to the predetermined value once more during a certain period of time (for example, 30 seconds elapses) A configuration for driving the means 3 may be used. Thereby, the possibility of erroneously detecting an earthquake can be reduced as much as possible.

  In the above embodiment, the rack and pinion 11 is used as the driving device for the restricting means 3. However, the present invention is not limited to this, and for example, an actuator using hydraulic pressure, pneumatic pressure, electromagnet or the like is used. It does not matter.

  In the said embodiment, although the structure which employ | adopted the discharge flow path 2 using hard resin was shown, this invention is not limited to this, Even if it is the structure which employ | adopted the discharge flow path using soft resin, I do not care. However, when the discharge flow path having this configuration is adopted, if the discharge flow path becomes long, the flow path may be bent and the sphere may be clogged. It is desirable to use when discharging downward.
