Description

  The present invention relates to a gaming ball displacement detection device for a gaming machine capable of detecting that the course of a gaming ball launched by an external force applied by a player is illegally changed.

  Conventionally, illegal acts on gaming machines (so-called pachinko machines) are continually over, and it is essential to take preventive measures against illegal acts on gaming machines. One of the illegal acts on a gaming machine is an act of illegally changing the course of the gaming ball by hitting the gaming machine in order to guide the launched gaming ball (pachinko ball) to a desired winning opening. In addition, as a countermeasure against such illegal acts, it has been proposed to provide a game machine with a sensor that can detect vibration (for example, Patent Documents 1 and 2).

Japanese Patent Publication No. 6-85816 JP 2004-223004 A

  However, in the above-described conventional configuration, although it is an original purpose to detect that the path of the game ball that has been launched is illegally changed and guided to the winning a prize opening, this is not detected directly. The vibration that is the factor is detected. For this reason, an over-detection occurs in which even a vibration that does not change the path of the game ball illegally is detected. Moreover, if the detection sensitivity is set so as to detect only a sufficiently large vibration that can illegally change the course of the game ball in fear of such a false detection, there is an increased risk of fraud. .

  The present invention has been made in view of such a situation, and makes it possible to detect without overdetection and without omission that the path of a game ball that has been launched is illegally changed and guided to the winning a prize opening. .

  In order to solve the above-described problems, a gaming ball displacement detection device for a gaming machine according to the present invention is mounted on a gaming machine and contains a sphere having the same weight and size as the gaming sphere, and the sphere by an external force applied to the gaming machine. Is a gaming ball displacement detection device that detects that the path of a game ball that has been launched has been illegally changed in the vicinity of the winning opening of the gaming machine due to displacement, and a container that houses the sphere inside, The spherical body is disposed inside the container, and the spherical body is movably mounted, and has a concave bottom having a cone shape constricted in a bowl shape in the center and the stationary spherical body at the bottom of the concave bottom. A restricting member for restricting the moving direction of the sphere by contacting the sphere moving on the dish by an external force applied to the gaming machine, a detecting means for detecting the sphere, and a plate having a stationary hole; Toward the stationary hole A pair of regulating members arranged symmetrically as viewed in the direction from which the external force is directed from the center of the stationary hole, on the side to which the external force that illegally changes the course of the game ball is directed. A detection region of the detection means is provided in a region between the pair of restricting members and outside an arc passing through the apexes of the pair of restricting members and concentric with the stationary hole. Is larger than the diameter of the sphere, and the linear distance between the vertices of the pair of restricting members is smaller than the diameter of the sphere.

  According to the above configuration, the sphere in the container is stationary on the stationary hole of the plate portion when the player is playing a normal game, but the player is launched against the gaming machine. When an external force that illegally changes the course of the game ball is applied, it rolls on the plate in the direction in which the external force is directed. Since the external force is applied exclusively by hitting the gaming machine from the front, the sphere rolls in the direction from the front side to the back side of the gaming machine.

  The sphere rolling on the dish part rolls up on the dish part to the back side of the gaming machine so as to go up the concave bottom, comes into contact with the pair of regulating members, and its movement direction is regulated and rebounded. When the sphere is bounced back in contact with the pair of regulating members, a part of the sphere instantaneously enters the detection area of the detection means, and the detection means detects the sphere that has instantaneously entered the detection area, Outputs detection pulse.

  The sphere bounced back in contact with the pair of regulating members is weakened by contacting the regulating member, and the direction of the bounce is regulated to the center of the concave bottom. Therefore, even if the sphere that has come into contact with the pair of regulating members and returned to the concave bottom again hits the wall surface of the container across the concave bottom and is returned to the concave bottom again, it does not come into contact with the pair of regulating members again. . Further, even if the applied external force is strong and the detection means is detected by contacting the pair of regulating members again, the momentum is further weakened by the contact with the regulating members again, so that the contact is not repeated many times. , Can be quickly returned to the stationary hole.

  In other words, according to the above configuration, the detection pulse output from the detection means is output only for a short period immediately after the external force for illegally changing the course of the game ball is applied, and continuously for a short time. Actions such as hitting a gaming machine can also be accurately detected according to the number of times the player is hit.

  In the gaming ball displacement detecting device of the gaming machine of the present invention, the side toward which an external force that illegally changes the course of the gaming ball is a back side of the gaming machine in a state of being attached to the gaming machine, The restricting member may be arranged in parallel with the back surface of the gaming machine.

  As described above, the external force that illegally changes the path of the launched game ball is applied by the action of hitting the game machine from the front, and the sphere rolls in the direction from the front side to the back side of the game machine. Therefore, as in the configuration described above, it is preferable that the pair of regulating members be arranged on the back side of the gaming machine in parallel with the back side.

  In this case, an attachment piece for attaching to the gaming machine is further provided, and the pair of restricting members are arranged in parallel with the attachment surface of the attachment surface, and the attachment piece is attached to the gaming machine. It is preferable that the mounting surface be mounted so as to be parallel to the back surface of the gaming machine.

  With such a configuration, a pair of regulating members can be mounted side by side on the back side of the gaming machine in parallel with the back surface only by attaching the mounting piece so that the mounting surface is parallel to the back surface of the gaming machine. it can.

  In the gaming ball displacement detecting device for a gaming machine according to the present invention, when the pair of regulating members is a first pair of regulating members, the side opposite to the side to which an external force that illegally changes the course of the gaming ball is directed. In addition, the second pair of restricting members may be arranged symmetrically as viewed in the direction in which the external force is applied from the center of the stationary hole.

  According to this, even if the sphere returned to the concave bottom in contact with the first pair of regulating members rolls to the opposite side beyond the concave bottom, the second pair of regulation arranged on the opposite side By contacting the member, the momentum is further weakened and the direction of rebound is also regulated to the center of the concave bottom. Therefore, the sphere can be returned to the stationary hole more quickly.

  In the gaming ball displacement detecting device of the gaming machine of the present invention, it is further preferable that the cone shape of the concave bottom is a polygonal pyramid shape, and / or the stationary hole for stopping the sphere is a polygonal shape. .

  The sphere rotates on the inner surface of the concave bottom and eventually rests on the stationary hole at the center of the concave bottom due to its own weight. When the conical shape of the concave bottom is a conical shape, the sphere smoothly rotates on the inner surface of the concave bottom, so that it takes time to stop. On the other hand, when the cone shape of the concave bottom is a polygonal pyramid shape, the sphere rotates while colliding with a plurality of surfaces of the concave bottom, so the kinetic energy decays faster than the cone shape, and the sphere Can be quickly rested on the stationary hole.

  In addition, when the shape of the stationary hole is also circular, the sphere that rotates on the stationary hole may be repelled by the edge of the stationary hole, and the stationary state may be delayed. The sphere to be moved can be easily stopped by the action of the corners of the stationary hole, and the sphere can be rested on the stationary hole more quickly.

  In the gaming ball displacement detection device for a gaming machine according to the present invention, the detection means further includes a coil and a high-frequency oscillation circuit that oscillates a high-frequency signal that is amplified by moving the sphere away from the vicinity of the coil. It is also possible to adopt a configuration in which a high-frequency oscillation circuit is provided in the annular coil characterized by

  According to this, the said detection means can be comprised easily.

  Further, the present invention is a fraud that determines that a fraud that illegally changes the course of a launched game ball has been made based on the result of the game ball displacement detection device of the present invention and the detection means of the game ball displacement detection device. A gaming machine including a determination unit, and a gaming machine of the present invention, an information processing apparatus that performs information processing using a determination result by a fraud determination unit notified from the gaming machine, and an information processing system including It is in that category.

  The present invention has an effect that it is possible to detect without overdetection and without omission that the path of the game ball that has been launched is illegally changed and guided to the winning opening.

  Hereinafter, embodiments of the present invention will be described in detail. FIG. 1 is an external view of a gaming machine according to an embodiment of the present invention. This gaming machine 1 is a so-called feathered object that is classified into two types in the former wind management law. However, the present invention can also be applied to gaming machines other than feathers.

  A pair of blades 13 and an accessory 12 are provided at the center of the board surface 21 of the gaming machine 1. The blade 13 guides the game ball to the accessory 12. While the blades 13 are opened, the game ball is guided into the accessory 12. The opening of the blades 13 is performed by the game balls entering the plurality of chuckers 11 provided at the lower part of the board surface 21. The bonus item 12 is provided with a V zone 14 which is a big hit when a game ball enters and a non-winning zone 15 which is not a big hit. Hereinafter, the chucker 11, the accessory 12, the V zone 14, and the like are collectively referred to as a winning opening, and a game ball entering the winning opening is described as winning.

  In the gaming machine 1 described above, the handle 17 is gripped by the player and rotated at a predetermined angle in the clockwise direction in the figure, so that the game ball is placed on the surface of the board surface 21 by a launching device (not shown). Fired (on the surface where the nail 22 is disposed). The game ball is fired on the surface of the board surface 21 and then hits the nail 22 driven into the surface of the board surface 21 and falls in various trajectories in the downward direction in the figure due to the action of gravity. Some items win the goods 12, the V zone 14, etc., and some items are collected in the collection hole at the bottom in the figure without winning.

  Even if a game ball wins a prize in the bonus item 12, if it enters the non-winning zone 15 instead of the V zone 14, it will not be a big hit. Therefore, from the psychology that somehow the game ball that has entered the bonus item 12 but not in the V zone 14 or the non-winning zone 15 is to be introduced into the V zone 14, A fraud may occur in which an external force is applied by hitting the main body and the path of the game ball is illegally displaced.

  In order to detect such fraud, the gaming machine 1 is equipped with a game ball displacement sensor (game ball displacement detection device) 23 for detecting an unauthorized displacement of the path of the game ball. As shown in FIGS. 1 and 2, here, the game ball displacement sensor 23 is attached at a position close to the V zone 14 on the back side of the board surface 21. FIG. 2 is a diagram schematically showing the mounting position of the game ball displacement sensor 23 in the gaming machine 1. Note that the position at which the game ball displacement sensor 23 is attached is not limited to the position close to the V zone 14, but is illegally displaced in the course of the game ball such as the chucker 11 on the back surface of the accessory 12 or the back surface of the board surface 21. It is good also as a position where is likely to occur. Moreover, you may attach to the front side of the board surface 21. FIG. Further, a plurality of game ball displacement sensors 23 may be attached.

  Next, a configuration example of the gaming machine 1 will be described with reference to FIG. FIG. 3 is a block diagram illustrating a configuration example of the gaming machine 1. In addition to the game ball displacement sensor 23, the gaming machine 1 includes a main control unit 31, an external interface (I / F) 32, a speaker 34, a voice control unit 33, a symbol display unit 36, a display control unit 35, an electric lamp 38, A lamp control unit 37, an operation unit 40, an operation control unit 39, and a notification unit 41 are provided.

  The main control unit 31 controls the entire gaming machine 1. The external interface (I / F) 32 is connected to the main control unit 31 and the hall computer 43 to communicate predetermined signals. The voice control unit 33 outputs voice from the speaker 34 in response to winning of an external game ball or the like. The symbol display unit 36 displays symbols corresponding to a winning of a game ball, etc., provided inside the accessory 12, and includes a liquid crystal display or the like. The display control unit 35 changes the screen display of the symbol display unit 36. The lamp control unit 37 blinks the electric lamp 38 provided on the board surface 21 in response to winning of a game ball or the like. The operation unit 40 detects the game ball in the above-described chucker 11, the accessory 12, the V zone 14, and the non-winning zone 15, the operation of the blade 13 depending on the presence / absence of a winning, and the mechanical effect in the accessory 12, etc. Detects game balls and performs mechanical operations. The operation control unit 39 transmits the detection result of the operation unit 40 to the main control unit 31 and controls the operation of the operation unit 40 based on an operation instruction from the main control unit 31. Based on an instruction from the main control unit 31, the notification unit 41 notifies the user of the occurrence of fraud in the gaming machine 1.

  Each gaming machine 1 installed in a game store (so-called pachinko store) is connected to a hall computer 43 provided for management of the game store. The hall computer 43 is notified of information such as the occurrence of an action. The hall computer 43 includes a display unit 44 that visually displays the status of each gaming machine 1 and a warning unit 45 that notifies a user (such as a store clerk of a game store) of the occurrence of an illegal act by a player. (An example of an information processing system including a gaming machine 1 and an information processing apparatus that performs information processing using a result of fraud determination notified from the gaming machine 1).

  When an unauthorized displacement is detected in the course of the game ball, the game ball displacement sensor 23 outputs a detection signal indicating that to the main control unit 31. Based on the detection signal from the game ball displacement sensor 23, the main control unit 31 determines the presence of an illegal act that illegally changes the course of the game ball and instructs the notification unit 41 to notify the user of the occurrence of the illegal act. Let me know. Further, the main control unit 31 notifies the hall computer 43 of a fraud detection signal indicating the occurrence of fraud via the external I / F 32. In response to the fraud detection signal being notified from each gaming machine 1, the hall computer 43 controls the warning unit 45 to notify the user (such as a store clerk of the amusement store) of the occurrence of the fraud.

  Next, a configuration example of the game ball displacement sensor 23 will be described with reference to FIGS. 4 is an external view of the game ball displacement sensor 23, FIG. 5 is an exploded perspective view of the game ball displacement sensor 23, and FIG. 6 is a partial cross-sectional view of the game ball displacement sensor 23. FIG. 7 is a diagram showing the arrangement of the metal ball 51, the coil 54, the concave bottom 60, and the stationary hole 66 in the game ball displacement sensor 23. FIG. 8 is a diagram showing the positional relationship between the detection regions of the rib 62, the metal ball 51, and the coil 54 in the game ball displacement sensor 23.

  The game ball displacement sensor 23 includes a metal ball 51, an upper cover 52, a case 53, a coil 54, a detection unit 55, and a bottom cover 56. The metal ball 51 has the same weight and size as the game ball. However, the weight and size of the metal ball 51 may not be exactly the same as that of the game ball. The metal ball 51 is placed on the top surface 61 of the case 53 so as to be movable (slidable). The top surface 61 of the case 53 has a substantially circular shape, and has a concave bottom 60 formed of a mortar-shaped or concave depression at the center. In addition, a circular stationary hole 66 for stationary the metal sphere 51 is provided at the lowermost part of the recess in the center of the concave bottom 60.

  The upper cover 52 is a bottomed cylindrical member fitted from above to the case 53 in a state where the metal ball 51 is placed. On the inner peripheral surface of the upper cover 52, a portion facing the metal ball 51 placed on the top surface 61 is an elongated projecting shape in contact with the metal ball 51 that moves (rolls) on the top surface 61. Ribs 62 are provided. The rib 62 is a regulating member that regulates the moving direction of the metal ball 51 when the metal ball 51 moving on the top surface 61 comes into contact with the rib 62.

  In the present embodiment, the four ribs 62 are in a cross (cross) direction centered on the center (central axis) 70 of the stationary hole 66 and are used for attachment to the gaming machine 1 (attachment) The piece is evenly arranged in the direction of the cross rotated 45 degrees with respect to the normal direction of the mounting surface of 69. Moreover, the shape of the cross section (cross section cut in the direction orthogonal to the longitudinal direction) in the rib 62 is, for example, a triangular shape with rounded vertices. Note that the cross-sectional shape of the rib 62 is not limited to this.

  The coil 54 varies the amplitude of the high-frequency signal in accordance with the displacement of the metal sphere 51 that moves on the top surface 61. The detection unit 55 generates a detection signal based on the amplitude fluctuation of the high-frequency signal. The coil 54 and the detection unit 55 are accommodated inside the case 53, and a bottom cover 56 is fitted to the bottom of the case 53.

  As shown in FIG. 7, the metal sphere 51, the coil 54, the concave bottom 60, and the stationary hole 66 are placed in the center 70 of the stationary hole 66 with the metal sphere 51 stationary on the stationary hole 66. The center axis of each of the coil 54 and the concave bottom 60 is configured to substantially coincide.

  Further, as shown in FIG. 8A, the detection region (hatched region) 65 of the coil 54 is an arc L1 (two-dot chain line) passing through the apex of each rib 62 and concentric with the stationary hole 66. Provided outside, the inside of the arc L1 is a non-detection region. The diameter of the arc L <b> 1 is larger than the diameter of the metal sphere 51, and the length of the straight line L <b> 2 (dashed line) connecting the vertices of the adjacent ribs 62 is set smaller than the diameter of the metal sphere 51. . As shown in FIG. 8B, when the metal ball 51 comes into contact with the pair of ribs 62 and a part of the metal ball 51 enters the outer peripheral portion of the arc L1 and moves onto the detection region 65, as shown in FIG. The displacement of the metal sphere 51 is detected, and the amplitude of the high frequency signal is varied.

  Such a game ball displacement sensor 23 is attached to the gaming machine 1 using the attachment flange 69 so that the top surface 61 of the case 53 is horizontal. In other words, the game ball displacement sensor 23 is mounted such that the mounting surface of the mounting flange 69 is parallel to the back surface of the gaming machine 1. The metal ball 51 placed on the top surface 61 is stationary on the stationary hole 66 by its own weight when no external force is applied. When an external force such as vibration is applied to the gaming machine 1, it swings on the concave bottom 60 around the stationary hole 66. When a force of a magnitude that causes the path of the game ball to be illegally displaced is applied, the metal ball 51 having the same weight and size as the game ball behaves in the same way as the game ball, and in the direction of the applied force. Accordingly, it rolls on the concave bottom 60 and comes into contact with the ribs 62 arranged around it.

  Due to the structure in which the gaming machine 1 is installed, the force for illegally displacing the path of the gaming ball is in the direction from the front to the back of the gaming machine 1. Therefore, the metal ball 51 rolls toward the back side, contacts the both of the pair of ribs 62 (first pair of restricting members) arranged on the back side almost simultaneously, and the direction of movement is regulated and rebounded.

  When the metal sphere 51 is bounced back almost simultaneously with both of the pair of ribs 62 arranged on the back side, a part of the metal sphere 51 instantaneously enters the detection region 65 of the coil 54, and the coil 54 The metal sphere 51 that instantaneously enters the detection region 65 is detected and a detection pulse is output (see (c) of FIG. 10).

  The metal sphere 51 bounced back in contact with both of the pair of ribs 62 arranged on the back side almost simultaneously causes the kinetic energy to be converted into frictional energy or absorbed by the rib 62. Become smaller and lose momentum. Moreover, the direction of the rebound is restricted to the center of the concave bottom 60 by contacting both of the pair of ribs 62 arranged on the back side almost simultaneously. The metal ball 51 bounced back and returned to the concave bottom 60 is almost simultaneously or both of the pair of ribs 62 (second pair of ribs) disposed on the front side opposite the concave bottom 60. In this case, the direction of rebound is restricted to the concave bottom 60 and is returned to the center of the concave bottom 60 again.

  Since the momentum of the metal sphere 51 weakens every time it contacts the rib 62, the metal sphere 51 bounced back by hitting both of the pair of ribs 62 on the front side almost simultaneously, or one by one in turn is again on the back side. There is little contact with both of the pair of ribs 62 almost simultaneously. Further, even if the applied external force is strong and again comes into contact with both of the pair of ribs 62 arranged on the back side almost simultaneously and is detected by the coil 54, the momentum is weakened by the contact with the ribs 62. In this case, the metal ball 51 is quickly returned onto the stationary hole 66 without being detected by the coil 54 repeatedly at almost the same time.

  9A to 9D show an example of the behavior of the metal ball 51 at times T1 to T4 when a force for illegally displacing the path of the game ball is applied, and a rib 62 is provided. The behavior is shown. (A) shows the state at time T1, and shows a state (solid line) in which the metal ball 51 is moved from the stationary position (one-dot chain line) and is in contact with both the pair of ribs 62 arranged on the back side. (B) shows the state at time T2, and from the state at time T1 (dashed line), the metal ball 51 is in contact with one rib 62 on the right side as viewed from the front side opposite to the back side (front side). Indicates the state (solid line). (C) shows a state at time T3, and shows a state (solid line) in which the metal ball 51 is in contact with one rib 62 on the left side when viewed from the front on the back side from the state at time T2 (dashed line). (D) shows a state at time T4, and shows a state (solid line) in which the metal ball 51 is in contact with the other rib 62 on the right side as viewed from the front on the back side from the state at time T3 (dashed line). Indicates. Moreover, in (a)-(d) of FIG. 9, the magnitude | size and direction of the force (external force) applied to the metal ball | bowl 51 are shown by the arrow.

  On the other hand, (a) to (d) in FIG. 10 show an example of the behavior of the metal ball 51 at times T1 to T4 when a force for illegally displacing the path of the game ball is applied. The behavior when it is not provided is shown. The magnitude and direction of the force applied to the metal ball 51 are the same as those in FIG. (A) shows the state at time T1, and shows a state (solid line) in which the metal ball 51 is moved from the stationary position (dashed line) and is in contact with the back side of the inner peripheral surface of the upper cover 52. (B) shows the state at time T2, and shows a state (solid line) where the metal sphere 51 returns from the state at time T1 (dashed line) to the center of the concave bottom 60. (C) shows the state at time T3, from which the metal ball 51 is in contact with the right side as seen from the front side of the inner peripheral surface of the upper cover 52 (solid line) from the state at time T2 (dashed line). Indicates. (D) shows a state at time T4, and shows a state (solid line) in which the metal ball 51 is in contact with the left side when viewed from the back side of the inner peripheral surface of the upper cover 52 from the state at time T3 (dashed line).

  As shown in FIGS. 9 and 10, the metal ball 51 has a top surface 61 due to a slight displacement in the left-right direction as viewed from the front, even when a force in the direction from the front to the back of the gaming machine 1 is applied. Rotate the top clockwise or counterclockwise and eventually stop. 9 and FIG. 10, the kinetic energy of the metal sphere 51 is absorbed quickly by repeatedly contacting the rib 62, and can be quickly stopped as compared with the configuration in which the rib 62 is not provided. Will be.

  Next, with reference to FIG. 11 and FIG. 12, a configuration in which the coil 54 and the detection unit 55 detect the metal ball 51 and detect that an illegal displacement has occurred in the course of the game ball based on the metal ball 51 will be described. To do.

  As shown in FIG. 11, the detection unit 55 includes an oscillation circuit unit 72, a comparison circuit unit 73, and an output circuit unit 74. FIG. 11 is a diagram illustrating a functional configuration of the detection unit 55. FIG. 12 is a diagram illustrating waveforms of output signals of the circuits constituting the detection unit 55. The oscillation circuit unit 72 generates a high-frequency signal and outputs the high-frequency signal to the coil 54, and oscillates a high-frequency signal whose amplitude is changed by moving the metal sphere 51 away from the vicinity of the coil 54 ((a in FIG. 12). )reference). The comparison circuit unit 73 generates a peak signal indicating fluctuations in the amplitude of the high-frequency signal, and compares the peak signal with a predetermined threshold value (two-dot chain line in FIG. 12A) and outputs a comparison signal. (See (b) of FIG. 12). The output circuit unit 74 outputs a detection signal including a detection pulse indicating that an illegal displacement has occurred in the course of the game ball based on the output of the comparison circuit unit 73 (see FIG. 12C). ). The detection signal is transmitted to the main control unit 31.

  FIG. 13 shows the relationship between the detection signal output from the output circuit unit 74 and the magnitude of the impact. In the case of a weak impact, even if the game ball has a size for illegally displacing it, the metal ball is bounced back by contacting a pair of ribs 62 arranged on the back side and returned to the center of the concave bottom 60 51 swings the non-detection region in the concave bottom 60 around the stationary hole 66, but does not contact the pair of ribs 62 again, and no detection pulse is output. Even if a very small portion of the metal sphere 51 enters the detection region 65 of the coil 54 without contacting the pair of ribs 62, the peak of the high-frequency signal in which the amplitude is changed in that case has a threshold value. Since it does not exceed, no detection pulse is output.

  On the other hand, in the case of a strong impact having a size for illegally displacing the game ball, the metal ball 51 bounced back in contact with the pair of ribs 62 arranged on the back side exceeds the concave bottom 60 and is on the front side. It collides with a pair of ribs 62 arranged on and is bounced back. In that case, a second detection pulse indicating the presence or absence of fraud is output. After that, when a pair of ribs 62 arranged on the back side is further contacted, a third detection pulse is output.

  However, as described above, the momentum of the metal sphere 51 is surely attenuated by coming into contact with the rib 62, so there is no possibility that a detection pulse will be generated beyond a predetermined time. Here, the predetermined time is a time shorter than a time corresponding to an interval between actions of continuously hitting the gaming machine. Therefore, according to such a configuration, the detection pulse output from the output circuit unit 74 is output only for a short period immediately after the external force for illegally changing the course of the game ball is applied, and the time is short. It is also possible to accurately detect an action such as hitting a gaming machine continuously according to the number of times of hitting.

  In the present embodiment, four ribs 62 are provided. However, only two ribs 62 may be provided corresponding to the direction in which the movement of the metal ball 51 due to unauthorized vibration is overwhelmingly generated. Specifically, in a state in which the game ball displacement sensor 23 is attached to the gaming machine 1, a direction in which the external force is applied in the direction in which the external force applied to illegally displace the path of the game ball is directed from the center of the stationary hole 66. The detection region of the coil 54 only needs to be provided outside a circular arc that is concentric with the stationary hole 66 and passes through the apexes of the pair of ribs 62.

  In the present embodiment, the rib 62 is provided on the inner peripheral portion of the upper cover 52. However, the rib 62 may be provided directly on the top surface 61, or may be formed of a separate member and disposed on the top surface 61. Also good.

  In addition, the detection unit 55 generates a peak signal indicating a variation in the amplitude of the high-frequency signal whose amplitude has been changed by the metal ball 51 entering the detection region of the coil 54, and compares the peak signal with a predetermined threshold value. The comparison signal is output, but by differentiating the peak signal, a differential signal indicating the speed of the amplitude change of the high-frequency signal is generated, and this is compared with a threshold value and the comparison signal is output. It is good.

  As another embodiment of the present invention, as shown in FIG. 14, the concave bottom 60A may be a polygonal pyramid shape and / or the stationary hole 66A may be a polygonal shape. With such a configuration, the metal ball 51 rolling so as to rotate in the concave bottom 60A can be returned to the stationary hole 66A more quickly.

  Specifically, the metal ball 51 rotates on the inner surface of the concave bottom 60 and eventually stops on the stationary hole 66 at the center of the concave bottom 60 by its own weight. When the concave bottom 60 has a conical shape, the metal sphere 51 smoothly rotates on the inner surface of the concave bottom 60, so that it takes time until the metal ball 51 stops. On the other hand, by making the concave bottom 60 into a polygonal pyramid shape, the metal sphere 51 rotates while colliding with a plurality of surfaces of the concave bottom 60, so that the kinetic energy decays faster than in the case of the conical shape. The sphere 51 can be quickly stopped on the stationary hole 66.

  Further, when the shape of the stationary hole 66 is also circular, the metal ball 51 rotating on the stationary hole 66 may be bounced to the edge of the stationary hole 66, and the stationary state may be delayed. The metal sphere 51 rotating on the stationary hole 66 is easily stationary by the action of the corners of the stationary hole 66, and the metal sphere 51 can be rested on the stationary hole 66 more quickly.

  As another embodiment of the present invention, as shown in FIG. 15, the coil 54A may have an oval shape instead of a circular shape. In the elliptical coil 54A, the sensitivity in the minor axis direction can be increased as compared with the sensitivity in the major axis direction. According to the configuration of FIG. 15, the sensitivity in the left-right direction is increased when viewed from the front, with the gaming ball displacement sensor 23 </ b> A attached to the gaming machine 1.

  The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope shown in the claims, and embodiments obtained by appropriately combining technical means disclosed in different embodiments. Is also included in the technical scope of the present invention.
